That is, the water drained from the drain hole 18 is configured not to drop into the range of the water tank cover 35 and the inner tank 1.
- the drain hole 18 is, for example, at an angle of approximately 45 degrees (including 45 degrees), below the inner tank 1 (outer peripheral side), that is, below the front side. It is formed to open toward. As a result, the water that has entered the housing part 5 is efficiently drained before it collects in the bottom part 5a of the housing part 5. Furthermore, even when the foam containing the detergent component generated from the inner tank 1 overflows from the water tank cover 35 and travels through the back surface 5b of the housing portion 5, the foam can be guided downward by the inclined surface of the drain hole 18. . As a result, it is possible to effectively prevent bubbles from entering the housing portion 5.

- a design gap is provided between the attachment surface 28 and the fitting portion of the operation panel 8 that fits the operation panel attachment surface 28 so that the fitting portion can be attached and detached. Therefore, when clothes are taken in and out through the clothes insertion port 4, water enters from the design gap. Therefore, the design gap is designed and formed so that the total cross-sectional area S2 corresponding to the opening area of the drain hole 18 (hereinafter abbreviated as “area S2”) is larger than the total cross-sectional area S1 of the design gap. is doing.
- the total cross-sectional area S1 of the design gap is the total cross-sectional area when the weir portion 17a of the first labyrinth portion 17 is cut in the circumferential direction of the first labyrinth portion 17 configured in an annular shape.
- the total cross-sectional area S1 of the design gap through which the entering water flows is abbreviated as the area S1 of the weir portion 17a.
- FIG. 7 is a cross-sectional view of an essential part for explaining the configuration of the weir portion and the relative positional relationship in the washing machine according to the present embodiment.
- the left figure of FIG. 7 has shown the cross section of the operation panel attachment surface 28 vicinity of the dam part 17a.
- the right figure of FIG. 7 has shown the cross section of the dam part 17a which comprises the 1st labyrinth part 17. As shown in FIG.
- the flow velocity of the water flowing through the area S01 is slower than the flow velocity of the water flowing through the area S02 by the height h01 higher than the operation panel mounting surface 28.
- the area S2 of the surface perpendicular to the water flow through the drain hole 18 is made larger than the area S1 of the weir portion 17a that is the sum of the areas S01 and S02. Therefore, when the flow rate flowing into the accommodating portion 5 is Q1, the flow velocity V1 of the water flowing through the area S1 of the weir portion 17a is expressed by (Equation 3). On the other hand, when the flow rate drained from the storage unit 5 is Q2, the flow velocity V2 flowing through the area S2 of the drain hole 18 is expressed by (Equation 4).
- the flow velocity V1 of the water flowing through the dam portion 17a area S1 is expressed by (Expression 6) when the water level of the inflow portion of the dam portion 17a is H1 (corresponding to the height from the operation panel mounting surface 28).
- the water accumulated in the accommodating portion 5 is larger than the water level H1 of the water flowing through the dam portion 17a of the first labyrinth portion 17.

- the 2nd rib 30 (rib 30) which constitutes the 2nd labyrinth part 29 (labyrinth part 29) of the 2nd waterproof part (waterproof part) is pinched by the 2nd groove 31 (groove 31).
- the length of the portion (the length in the height direction) is made longer than the width of the second groove 31 (the width of the cross section).
- the weir portion 17a of the first labyrinth portion 17 has a labyrinth structure so that the design gap between the first rib 25 and the first groove 26 flows.
- the water flow path can be narrowed and lengthened with a compact configuration. For this reason, the flow rate of the first labyrinth portion 17 flowing through the weir portion 17a can be reduced, and water can be efficiently prevented from entering the operation substrate 9.
- the position of the first rib 25 of the operation panel 8 is, for example, the front of the washing machine main body 2 (FIG. 1) due to processing variations of parts constituting the operation panel 8 and the housing 5 and the like. Even when it is shifted to the left), the gap between the first rib 25 and the front side of the washing machine body 2 of the first groove 26 is narrowed. For this reason, water can be prevented from entering the housing portion 5 via the weir portion 17a of the first labyrinth portion 17, so that the waterproof effect on the operation substrate 9 is not lowered. Similarly, even when the position of the first rib 25 of the operation panel 8 is shifted to the rear of the washing machine body 2 (right side in FIG.

It can be hard to collect. Further, the second labyrinth part 29 (labyrinth part 29) constituting the second waterproof part causes scattered water generated when water entered from the weir part 17a of the first labyrinth part 17 flows, or drains water. Intrusion of foreign matter such as water vapor and insects entering through the hole 18 into the operation substrate 9 can be prevented. As a result, the operation substrate 9 need not be waterproofed by being covered with the potting agent 24.
- the operation substrate 9 is not subjected to thermal stress due to the potting agent 24 or mechanical stress due to contraction, warping of components such as the operation substrate 9 can be suppressed.
- the positional deviation between the operation panel 8 and the operation board 9 and the relative position between the operation button 7 and the display unit 6 attached to the operation panel 8 and the operation switch 10 attached to the operation board 9 can be stabilized.

そして、収容部106の底部106aには、水槽101の外周壁よりも内側に相当する位置に、水抜き孔118が設けられている。これにより、衣類を内槽100に出し入れする際に、当接部117から収容部106内に水が浸入した場合、浸入した水を水抜き孔118を介して水槽101内に排出している。
And in the bottom part 106a of the accommodating part 106, the drain hole 118 is provided in the position corresponded inside the outer peripheral wall of the water tank 101. As shown in FIG. As a result, when the clothing enters and leaves the inner tub 100 and water enters the housing portion 106 from the contact portion 117, the intruded water is discharged into the water tub 101 through the drain hole 118.
また、図10に示すように、操作装置130の一部を構成する操作基板105は、商用電源に電気的に接続された電源スイッチ119と、洗濯機の制御を行うマイクロコンピュータ120とを有している。そして、操作基板105は、第1の舟状保護ケース113aに固定された後、ポッティング剤124が充填される。これにより、操作基板105は、ポッティング剤124で被覆されて、防水される。その結果、衣類投入口104から衣類を出し入れする際に衣類から落ちる水や、洗濯機を屋外に設置した場合の降雨による水が、第1の舟状保護ケース113aに浸入した場合でも、浸入した水による操作基板105のパターン間抵抗の低下を防止できる。特に、操作基板105に実装されているマイクロコンピュータ120は、端子間の空間(ピッチ)が短いため、パターン間抵抗のわずかな変化でも、マイクロコンピュータ120の動作が影響を受ける。また、電源スイッチ119は、商用電源と接続されるので、電源スイッチ119内に水分が浸入するとショートしやすくなる。そこで、操作基板105をポッティング剤124の充填により被覆して防水・防湿対策をしている。その結果、第1の舟状保護ケース113a内に水が浸入しても、ポッティング剤124により操作基板105への水の浸入を阻止して、洗濯機の誤表示や誤動作を防止することができる。
As shown in FIG. 10, the operation board 105 constituting a part of the operation device 130 includes a power switch 119 electrically connected to a commercial power source and a microcomputer 120 that controls the washing machine. ing. The operation substrate 105 is fixed to the first boat-like protective case 113a and then filled with the potting agent 124. Thereby, the operation substrate 105 is covered with the potting agent 124 and waterproofed. As a result, even when the water falling from the clothes when the clothes are put in and out of the clothes insertion port 104 or the water due to the rain when the washing machine is installed outdoors enters the first boat-like protective case 113a, the water has entered. It is possible to prevent a decrease in resistance between patterns of the operation substrate 105 due to water. In particular, since the microcomputer 120 mounted on the operation board 105 has a short space (pitch) between terminals, even a slight change in inter-pattern resistance affects the operation of the microcomputer 120. In addition, since the power switch 119 is connected to a commercial power source, short circuiting easily occurs when moisture enters the power switch 119. Therefore, the operation substrate 105 is covered with a potting agent 124 to take measures against water and moisture. As a result, even if water enters the first boat-like protective case 113a, the potting agent 124 prevents water from entering the operation board 105, thereby preventing erroneous display and malfunction of the washing machine. .
また、図12に示すように、電源装置140を構成する電源基板111は、第2の舟状保護ケース113bを覆う第1の金属カバー121と、電源基板111に接続するコネクタ122側を覆う、第2の金属カバー123によって覆われている。そして、電源基板111は、第2の舟状保護ケース113bに固定された後、ウレタン樹脂などからなるポッティング剤124が充填される。これにより、電源基板111がポッティング剤124で被覆されて、防水される。
As shown in FIG. 12, the power supply substrate 111 constituting the power supply device 140 covers the first metal cover 121 that covers the second boat-like protective case 113 b and the connector 122 side that is connected to the power supply substrate 111. Covered with a second metal cover 123. The power supply substrate 111 is fixed to the second boat-like protective case 113b and then filled with a potting agent 124 made of urethane resin or the like. Thereby, the power supply substrate 111 is covered with the potting agent 124 and waterproofed.
以上のように従来の洗濯機は構成されている。
As described above, the conventional washing machine is configured.
以下に、従来の洗濯機の洗濯動作について、簡単に説明する。
The following briefly describes the washing operation of a conventional washing machine.
まず、内槽100に洗濯物と水および洗剤を投入する。つぎに、電源スイッチ119および操作スイッチ110の操作により、モータ112を駆動して内槽100を回転駆動する。このとき、内槽100の回転で発生した水の流れにより、洗濯物が動かされる。これにより、洗濯物同士、または内槽100との接触による擦れにより洗濯が行われる。
First, the laundry, water and detergent are put into the inner tub 100. Next, by operating the power switch 119 and the operation switch 110, the motor 112 is driven to rotationally drive the inner tank 100. At this time, the laundry is moved by the flow of water generated by the rotation of the inner tub 100. Thereby, washing is performed by rubbing due to contact between the laundry or the inner tub 100.
つぎに、脱水は、まず、内槽100に洗濯物を投入する。そして、操作スイッチ110の操作により、モータ112を駆動して内槽100を高速回転させる。このとき、高速回転する内槽100の遠心力により、洗濯物から水分が分離され、脱水が行われる。
Next, for dehydration, first, the laundry is put into the inner tub 100. Then, by operating the operation switch 110, the motor 112 is driven to rotate the inner tub 100 at a high speed. At this time, moisture is separated from the laundry by the centrifugal force of the inner tub 100 rotating at high speed, and dehydration is performed.
つぎに、脱水した洗濯物を内槽100から取り出して乾燥する。なお、乾燥機能付きの洗濯機の場合は、そのまま乾燥を行う。
Next, the dehydrated laundry is taken out from the inner tub 100 and dried. In the case of a washing machine with a drying function, drying is performed as it is.
以上の動作により、洗濯機の洗濯動作が行われる。
The washing operation of the washing machine is performed by the above operation.
しかしながら、従来の洗濯機の構成では、洗濯中に発生した泡が、内槽100から溢れ出し、さらに水槽カバー101aをも超えて溢れ出した場合、収容部水抜き孔118から収容部106に泡が浸入する。このとき、浸入した泡は、第1の舟状保護ケース113aと収容部106との隙間や、第1の舟状保護ケース113aと操作パネル109との隙間などから操作基板105の区域内に浸入する。そして、浸入した泡に含まれる洗剤水の界面活性作用により、操作スイッチ110や、マイクロコンピュータ120の端子間抵抗が低下する。その結果、表示部107が誤表示したり、商用電源に接続された電源スイッチ119の区域内でのトラッキング現象により誤動作が発生するという課題があった。
However, in the configuration of the conventional washing machine, when the foam generated during washing overflows from the inner tub 100 and further overflows beyond the water tank cover 101a, the foam is generated from the storage portion drain hole 118 to the storage portion 106. Invades. At this time, the infiltrated bubbles enter the area of the operation board 105 from the gap between the first boat-like protective case 113a and the accommodating portion 106, the gap between the first boat-like protective case 113a and the operation panel 109, or the like. To do. Then, the interfacial resistance of the operation switch 110 and the microcomputer 120 decreases due to the surface active action of the detergent water contained in the infiltrated foam. As a result, there is a problem in that the display unit 107 erroneously displays or malfunction occurs due to a tracking phenomenon in the area of the power switch 119 connected to the commercial power source.
上記課題を解決するために、本発明は、少なくとも洗濯機本体と、洗濯物を収容する内槽と、内槽を収容する水槽と、水槽の上端を覆う水槽カバーと、洗濯機本体の上部に設けられる上部外郭とを備えた洗濯機である。そして、操作が入力される操作基板と、操作基板を保護する保護ケースと、上部外郭に設けられ、保護ケースを収容する、底部を有する収容部と、底部に設けられた水抜き孔と、を備えている。さらに、収容部内部には、操作基板を防水する防水部が設けられ、水抜き孔は、水槽カバーの外周よりも外側に設けられている。
In order to solve the above-described problems, the present invention provides at least a washing machine main body, an inner tub for storing laundry, a water tub for storing an inner tub, a water tank cover for covering the upper end of the water tub, and an upper portion of the washing machine main body. It is a washing machine provided with the upper outline provided. Then, an operation board to which an operation is input, a protective case for protecting the operation board, an accommodation part having a bottom part that is provided in the upper outer shell and accommodates the protection case, and a drain hole provided in the bottom part, I have. Further, a waterproof part for waterproofing the operation board is provided inside the accommodating part, and the drain hole is provided outside the outer periphery of the water tank cover.
これにより、洗濯中に内槽で発生した泡が、水槽カバーを超えて溢れ出した場合でも、水抜き孔に到達する前に、洗濯機本体の下方に落下する。そのため、水抜き孔から収容部に泡や水が浸入しない。その結果、操作基板の区域内への泡や水の浸入を防止して、誤表示や誤動作が発生しない信頼性に優れた洗濯機を実現できる。
This allows foam generated in the inner tub during washing to fall below the washing machine body before reaching the drain hole even if it overflows beyond the water tank cover. Therefore, bubbles and water do not enter from the drain hole into the housing portion. As a result, it is possible to achieve a highly reliable washing machine that prevents bubbles and water from entering the area of the operation board and does not cause erroneous display or malfunction.

図1から図6に示すように、本実施の形態の洗濯機は、少なくとも洗濯機本体2に内包された水受け槽40(以下、「水槽」と記す)およびモータ(図示せず)の回転軸により回転自在に支持された洗濯兼脱水槽1(以下、「内槽」と記す)と、洗濯機本体2の上部全体をほぼ覆うように装着された、例えばポリプロピレンで成形された上部外郭3と、電源装置60を備える操作装置50と、から構成されている。そして、内槽1は水槽40内に回転自在に内包され、水槽40の下部にはモータが装着されている。なお、本実施の形態では、水槽40を有する洗濯機を例に説明するが、内槽1のみで水槽40のない構成の洗濯機でもよいことはいうまでもない。
As shown in FIGS. 1 to 6, the washing machine of the present embodiment has at least a water receiving tank 40 (hereinafter referred to as “water tank”) and a motor (not shown) included in the washing machine body 2. A washing and dewatering tub 1 (hereinafter referred to as an “inner tub”) rotatably supported by a shaft, and an upper shell 3 made of, for example, polypropylene, mounted so as to substantially cover the entire upper portion of the washing machine body 2. And an operating device 50 including a power supply device 60. And the inner tank 1 is included in the water tank 40 so that rotation is possible, and the motor is mounted to the lower part of the water tank 40. In the present embodiment, a washing machine having a water tub 40 will be described as an example, but it goes without saying that a washing machine having only the inner tub 1 and no water tub 40 may be used.
上部外郭3の略中央(中央を含む)には、上部外郭3に一体に衣類投入口4が成形されている。このとき、縦型洗濯機の場合、衣類投入口4は、内槽1の上方に向けて下方向に伸延して構成されている。
A clothing input port 4 is formed integrally with the upper shell 3 at the approximate center (including the center) of the upper shell 3. At this time, in the case of a vertical washing machine, the clothing input port 4 is configured to extend downward toward the upper side of the inner tub 1.
また、上部外郭3の正面側(図1の左側に相当)には、略凹状(凹状を含む)の収容部5が形成されている。収容部5は、洗濯機本体2の正面側と、衣類投入口4の間の位置で、図5に示すように、上部外郭3の全体幅(図1の紙面と直交する方向)とほぼ同じ幅で設けられている。そして、収容部5は、例えばPETシート(ポリエチレンテレフタラートシート)に印刷された表示部6および、操作ボタン7を有する、例えばポリプロピレンで成形された操作パネル8により、ほぼ全体が覆われている。なお、表示部6の裏面には、操作ボタン7に対応する部位に開けられた孔を除いて、ほぼ全体にわたって、例えば両面テープ(図示せず)が設けられ、両面テープを介して操作パネル8の表面に表示部6が貼り付けられている。
Further, on the front side of the upper shell 3 (corresponding to the left side in FIG. 1), a substantially concave (including concave) accommodating portion 5 is formed. As shown in FIG. 5, the accommodating portion 5 is substantially the same as the entire width of the upper shell 3 (in the direction orthogonal to the paper surface of FIG. 1) at a position between the front side of the washing machine body 2 and the clothing insertion port 4. It is provided in width. The accommodating portion 5 is almost entirely covered with an operation panel 8 having, for example, a display portion 6 printed on a PET sheet (polyethylene terephthalate sheet) and operation buttons 7 and formed of, for example, polypropylene. Note that, for example, a double-sided tape (not shown) is provided on the back surface of the display unit 6 except for a hole opened in a portion corresponding to the operation button 7, and the operation panel 8 is provided via the double-sided tape. The display part 6 is affixed on the surface.
また、操作パネル8の操作ボタン7と対応する位置には、操作基板9に実装された操作スイッチ10が配置されている。
Further, an operation switch 10 mounted on the operation board 9 is disposed at a position corresponding to the operation button 7 of the operation panel 8.
そして、洗濯機を操作する場合、収容部5の底部5aに相当する内側から、操作基板9の表面、操作スイッチ10、操作ボタン7、表示部6の順で部品が配置され、使用者が操作する操作面6aに達するように構成されている。つまり、使用者が操作面6aから操作ボタン7を押すことにより、操作パネル8の操作ボタン7を介して操作基板9に操作が入力される。これにより、使用者は、洗濯機の運転や洗濯動作を選択できる。
When the washing machine is operated, components are arranged in the order of the surface of the operation board 9, the operation switch 10, the operation button 7, and the display unit 6 from the inside corresponding to the bottom 5a of the storage unit 5, and are operated by the user. The operation surface 6a is configured to reach the operation surface 6a. That is, when the user presses the operation button 7 from the operation surface 6 a, an operation is input to the operation board 9 via the operation button 7 of the operation panel 8. Thereby, the user can select the operation of the washing machine and the washing operation.
また、収容部5には、電源装置60を備える操作装置50が内包されている。操作装置50は、少なくとも電源装置60と、操作パネル8と、操作基板9と、舟状保護ケース13(以下、「保護ケース13」と略記する)と、から構成されている。このとき、保護ケース13は、例えば難燃ABS樹脂により成形された、例えば断面形状が略H形(H形を含む)で少なくとも2つの凹部13a、13bを有している。操作装置50の操作基板9は、保護ケース13の凹部13aに内包されている。
In addition, the storage unit 5 includes an operation device 50 including a power supply device 60. The operation device 50 includes at least a power supply device 60, an operation panel 8, an operation board 9, and a boat-like protective case 13 (hereinafter abbreviated as “protective case 13”). At this time, the protective case 13 is formed of, for example, a flame retardant ABS resin, and has, for example, a substantially H-shaped (including H-shaped) cross-sectional shape and at least two concave portions 13a and 13b. The operation board 9 of the operation device 50 is enclosed in the recess 13 a of the protective case 13.
また、電源装置60は、少なくとも電源基板11と、電源基板11を被覆するポッティング剤24と、保護ケース13とから構成されている。具体的には、電源装置60は、保護ケース13の凹部13bに、ポッティング剤24で被覆した電源基板11を内包して構成されている。電源基板11は、内槽1の下部に装着されたモータ(図示せず)などの負荷への電力の供給を制御する。
The power supply device 60 includes at least the power supply substrate 11, the potting agent 24 covering the power supply substrate 11, and the protective case 13. Specifically, the power supply device 60 is configured by enclosing the power supply substrate 11 covered with the potting agent 24 in the recess 13 b of the protective case 13. The power supply board 11 controls the supply of electric power to a load such as a motor (not shown) attached to the lower part of the inner tank 1.
つまり、操作装置50を構成する保護ケース13の一方の面側(操作パネル8と対向する側)の凹部13aには操作基板9が内包され、例えば水などから保護している。一方、保護ケース13の他方の面側(収容部5の底部5aと対向する側)の凹部13bには、電源装置60を構成する電源基板11が内包され、例えば水などから保護している。このとき、操作基板9はポッティング剤の充填処理がされず、電源基板11のみがポッティング剤24で充填処理され被覆されている。これにより、操作基板9は、ポッティング剤24の硬化時の熱ストレスや、ポッティング剤24の収縮による機械的ストレスを受けることがない。
That is, the operation board 9 is included in the recess 13a on one surface side (the side facing the operation panel 8) of the protective case 13 constituting the operation device 50, and is protected from, for example, water. On the other hand, the power supply substrate 11 constituting the power supply device 60 is included in the recess 13b on the other surface side (the side facing the bottom portion 5a of the housing portion 5) of the protective case 13, and is protected from, for example, water. At this time, the operation substrate 9 is not filled with the potting agent, and only the power supply substrate 11 is filled and covered with the potting agent 24. Thereby, the operation substrate 9 is not subjected to thermal stress when the potting agent 24 is cured or mechanical stress due to contraction of the potting agent 24.
なお、操作基板9は、図2と図5に示すように、操作ボタン7近傍の操作パネル8に一体に成形されて設けられた操作基板取り付けボス14に、操作基板取り付けビス15により固定されている。具体的には、操作基板9は、操作基板取り付けビス15を操作スイッチ10近傍の操作基板9に開けられた孔(図示せず)を貫通させ、操作基板取り付けボス14に締め付けることにより操作パネル8と固定されている。
2 and 5, the operation board 9 is fixed to an operation board mounting boss 14 formed integrally with the operation panel 8 in the vicinity of the operation button 7 by an operation board mounting screw 15. Yes. Specifically, the operation board 9 is configured such that the operation board mounting screw 15 passes through a hole (not shown) formed in the operation board 9 near the operation switch 10 and is tightened to the operation board mounting boss 14. And are fixed.
また、図1に示すように、操作ボタン7に対応する位置の表示部6の操作面6aは、外方に向かって凸部形状で構成されている。このとき、表示部6と操作ボタン7との間は隙間g1、操作ボタン7と操作スイッチ10との間は隙間g2で設計されている。さらに、操作スイッチ10は、回路を開閉するまでのストロークs1に設定されている。そして、表示部6の凸部形状の高さh1は、下記(数1)の関係を満足するように構成されている。
Further, as shown in FIG. 1, the operation surface 6a of the display unit 6 at a position corresponding to the operation button 7 is formed in a convex shape toward the outside. At this time, the gap g1 is designed between the display unit 6 and the operation button 7, and the gap g2 is designed between the operation button 7 and the operation switch 10. Further, the operation switch 10 is set to a stroke s1 until the circuit is opened and closed. The height h1 of the convex shape of the display unit 6 is configured to satisfy the following relationship (Equation 1).
(数1)
h1×2≧g1+g2+s1 (1) (Equation 1)
h1 × 2 ≧ g1 + g2 + s1 (1)
h1×2≧g1+g2+s1 (1) (Equation 1)
h1 × 2 ≧ g1 + g2 + s1 (1)
そして、表示部6の凸部形状の操作面6aを押し下げたとき、操作面6aは、操作スイッチ10の後方に変位する。そのため、操作面6aの凸部形状は、高さh1となるようにあらかじめ材料を引き伸ばして形成されている。つまり、操作面6aを押し下げると、操作面6aの凸部形状が反転して、高さh1の凹部形状になるまで、つまり、高さh1×2の変位までは、操作面6aの材料が伸びずに、軽い操作力で操作面6aを変位させることができる。このとき、(数1)に示すように、操作面6aが高さh1×2だけ変位する距離は、隙間g1、隙間g2にストロークs1を加えた値となる。これにより、表示部6を構成する材料の伸びによらず、凸部形状の操作面6aが反転する未満のストロークで操作スイッチ10のストロークs1を押し切ることができる。
Then, when the convex shaped operation surface 6 a of the display unit 6 is pushed down, the operation surface 6 a is displaced to the rear of the operation switch 10. Therefore, the convex shape of the operation surface 6a is formed by stretching the material in advance so as to have the height h1. That is, when the operation surface 6a is pushed down, the convex shape of the operation surface 6a is reversed, and the material of the operation surface 6a is stretched until the height h1 becomes a concave shape, that is, until the height h1 × 2 is displaced. In addition, the operation surface 6a can be displaced with a light operation force. At this time, as shown in (Expression 1), the distance that the operation surface 6a is displaced by the height h1 × 2 is a value obtained by adding the stroke s1 to the gap g1 and the gap g2. As a result, the stroke s1 of the operation switch 10 can be pushed out with a stroke that is less than the inversion of the convex-shaped operation surface 6a regardless of the elongation of the material constituting the display unit 6.
さらに、操作ボタン7の一部には、操作スイッチ10のさらに下の位置まで伸延した水切り部7aが、少なくとも洗濯機の正面側に設けられている。これにより、例えば操作パネル8の裏面(収容部5側)で水蒸気が結露した場合、操作基板9に実装された操作スイッチ10に、結露した水が滴下することを防止している。
Further, a part of the operation button 7 is provided with a draining portion 7a extending to a position further below the operation switch 10 at least on the front side of the washing machine. Thereby, for example, when water vapor is condensed on the back surface (accommodating portion 5 side) of the operation panel 8, the condensed water is prevented from dripping onto the operation switch 10 mounted on the operation board 9.
また、図1に示すように、保護ケース13には電源基板11を固定する電源基板固定爪16が形成され、電源基板固定爪16を介して電源基板11の周囲が係止されて保護ケース13の凹部13bに内包されている。
Further, as shown in FIG. 1, a power supply board fixing claw 16 for fixing the power supply board 11 is formed in the protective case 13, and the periphery of the power supply board 11 is locked via the power supply board fixing claw 16 to protect the protective case 13. Is contained in the recess 13b.
また、図1に示すように、収容部5の縁部のほぼ全周には操作パネル8と当接するラビリンス構造で堰部17aを有する第1のラビリンス部17が形成されている。そして、収容部5は、例えばビスや爪などにより操作パネル8に固定されている。さらに、収容部5の底部5aには水抜き孔18が設けられ、衣類を内槽1に出し入れする際、第1のラビリンス部17から収容部5内に浸入した水を洗濯機の下方に排水する。これにより、第1の防水部が、第1のラビリンス部17と水抜き孔18とから構成される。なお、堰部17aは、第1のラビリンス部17のうち内槽1の衣類投入口4側に位置する端部側に形成された第1のラビリンス部17に相当する。
Further, as shown in FIG. 1, a first labyrinth portion 17 having a weir portion 17 a having a labyrinth structure that abuts the operation panel 8 is formed on substantially the entire circumference of the edge portion of the accommodating portion 5. And the accommodating part 5 is being fixed to the operation panel 8 with the screw | screw, the nail | claw, etc., for example. Further, a drain hole 18 is provided in the bottom 5a of the container 5, and when the clothes are taken in and out of the inner tub 1, the water that has entered the container 5 from the first labyrinth part 17 is drained below the washing machine. To do. As a result, the first waterproof part is constituted by the first labyrinth part 17 and the drain hole 18. In addition, the dam part 17a is corresponded to the 1st labyrinth part 17 formed in the edge part side located in the clothing input port 4 side of the inner tank 1 among the 1st labyrinth parts 17. FIG.
また、図3と図5に示すように、保護ケース13の一部には、商用電源に電気的に接続した電源スイッチ19が、例えば固定爪(図示せず)などを介して装着されている。そして、洗濯機の制御を行うマイクロコンピュータ20は、図1に示すように、電源基板11に装着されている。
As shown in FIGS. 3 and 5, a power switch 19 that is electrically connected to a commercial power source is attached to a part of the protective case 13 via, for example, a fixing claw (not shown). . And the microcomputer 20 which controls a washing machine is mounted | worn with the power supply board 11, as shown in FIG.

Furthermore, lead parts (not shown) of components such as the lead part 10a of the operation switch 10 and the connector 22 mounted on the operation board 9 and the power supply board 11 constituting the operation device 50 are connected to the operation board 9 and the power supply board 11. Even if it protrudes from the back surface, the first resin layer 13c and the second resin layer 13d of the protective case 13 having high insulation properties are brought into contact with the first incombustible cover 21 of the protective case 13 before contacting. Therefore, it is possible to prevent a decrease in resistance between the lead parts of the component. As a result, the operation device 50 having the power supply device 60 with excellent reliability and the washing machine capable of preventing malfunctions and display errors can be realized.
また、電源装置60は、保護ケース13に電源基板11を固定した後、例えばウレタン樹脂などからなる防湿用のポッティング剤24を、電源基板11を内包した保護ケース13の凹部13b内に充填し、電源基板11のほぼ全体を被覆して構成されている。
In addition, after fixing the power supply substrate 11 to the protective case 13, the power supply device 60 fills the recess 13 b of the protective case 13 containing the power supply substrate 11 with a moisture-proof potting agent 24 made of, for example, urethane resin. The power supply substrate 11 is configured so as to cover almost the whole.
つまり、操作装置50は、表示部6、操作パネル8の操作ボタン7、操作スイッチ10、操作基板9、隙間A、保護ケース13の第1の樹脂層13c、第1の不燃カバー21、保護ケース13の第2の樹脂層13d、ポッティング剤24を充填した空間、電源基板11、ポッティング剤24を充填した空間、コネクタ22、第2の不燃カバー23、隙間Bとから構成され、表示部6から収容部5の底部5aまで順番に配置されている。なお、隙間Aとは、操作スイッチ位置決めピン39で決められる操作基板9と保護ケース13の第1の樹脂層13cとの間の空間に相当する。隙間Bとは、第2の不燃カバー23と収容部5の底部5aとで挟まれる空間に相当する。
That is, the operation device 50 includes the display unit 6, the operation button 7 of the operation panel 8, the operation switch 10, the operation board 9, the gap A, the first resin layer 13c of the protective case 13, the first non-combustible cover 21, and the protective case. 13 of the second resin layer 13d, the space filled with the potting agent 24, the power supply substrate 11, the space filled with the potting agent 24, the connector 22, the second incombustible cover 23, and the gap B. It arrange | positions in order to the bottom part 5a of the accommodating part 5. FIG. The gap A corresponds to a space between the operation board 9 and the first resin layer 13c of the protective case 13 determined by the operation switch positioning pins 39. The gap B corresponds to a space sandwiched between the second incombustible cover 23 and the bottom portion 5a of the housing portion 5.

以下に、本実施の形態の特徴である操作装置50内に設けられる第1のラビリンス部と第2のラビリンス部(ラビリンス部)の構成および機能について、詳細に説明する。
Hereinafter, configurations and functions of the first labyrinth unit and the second labyrinth unit (labyrinth unit) provided in the operation device 50, which is a feature of the present embodiment, will be described in detail.
まず、図1に示すように、第1のラビリンス部17は、操作パネル8の一部を下方に伸延した第1のリブ25と、第1のリブ25を狭持する収容部5の端部の、例えばほぼ全周に形成された断面形状が略U字形状(U字形状を含む)の第1の溝26と、から構成されている。そして、第1のリブ25と第1の溝26との隙間を狭く設計して第1のラビリンス部17を構成することにより、収容部5内に水が入りにくい防水構造を実現している。これにより、第1の防水部が構成される。
First, as shown in FIG. 1, the first labyrinth portion 17 includes a first rib 25 that extends a part of the operation panel 8 downward, and an end portion of the housing portion 5 that holds the first rib 25. For example, the first groove 26 having a substantially U-shaped (including U-shaped) cross-sectional shape formed on substantially the entire circumference is formed. The first labyrinth part 17 is configured by designing the gap between the first rib 25 and the first groove 26 to be narrow, thereby realizing a waterproof structure in which water does not easily enter the housing part 5. Thereby, a 1st waterproof part is comprised.
なお、第1のラビリンス部17のほぼ全周とは、一部が配線やビス止めなどにより欠けているような構造を意味し、必ずしも全周にわたってラビリンス構造である必要がないことはいうまでもない。また、第1のラビリンス部17は、第1のリブ25と第1の溝26の一部が当接する構造でもよく、同様の効果を得ることができる。さらに、第1のラビリンス部17は、図5に示す洗濯機の幅方向で衣類投入口4側に設けられる堰部17aのみで構成する場合も含んでいる。
Note that the substantially entire circumference of the first labyrinth portion 17 means a structure in which a part is missing due to wiring or screwing, and it is needless to say that the labyrinth structure is not necessarily required over the entire circumference. Absent. The first labyrinth portion 17 may have a structure in which the first rib 25 and a part of the first groove 26 are in contact with each other, and the same effect can be obtained. Furthermore, the 1st labyrinth part 17 includes the case where it comprises only the dam part 17a provided in the clothing input port 4 side in the width direction of the washing machine shown in FIG.
このとき、図4と図5に示すように、衣類投入口4側の操作パネル8の左右(幅方向)両端近傍に設けたビス孔27aと対応する位置の収容部5には、操作パネル取り付け面28が形成されている。操作パネル取り付け面28は、収容部5の端部に形成された第1の溝26を切り欠いて構成され、例えば2箇所のボス部28aを有している。そして、操作パネル取り付け面28を介して、例えば2本の操作パネル取り付けビス27で、操作パネル8のビス孔27aを介してボス部28aでビス止めすることによって、操作パネル8と収容部5とが固定される。
At this time, as shown in FIGS. 4 and 5, the operation panel is attached to the accommodating portion 5 at a position corresponding to the screw holes 27 a provided in the vicinity of both the left and right (width direction) ends of the operation panel 8 on the clothing insertion port 4 side. A surface 28 is formed. The operation panel mounting surface 28 is configured by cutting out the first groove 26 formed at the end of the accommodating portion 5 and has, for example, two boss portions 28a. Then, for example, two operation panel mounting screws 27 are screwed with a boss portion 28a through a screw hole 27a of the operation panel 8 through the operation panel mounting surface 28, whereby the operation panel 8 and the accommodating portion 5 are fixed. Is fixed.
また、図1に示すように、第2のラビリンス部29(ラビリンス部29)は、操作パネル8の一部を下方に向けて伸延した第2のリブ30(リブ30)と、第2のリブ30を狭持する保護ケース13の凹部13aを構成する外周端部のほぼ全周に形成された断面形状が略U字形状(U字形状を含む)の第2の溝31(溝31)とから構成されている。そして、第2のリブ30(リブ30)と第2の溝31(溝31)との隙間を狭く設計して第2のラビリンス部29(ラビリンス部29)を構成することにより、操作基板9側の保護ケース13内に水が入りにくい防水構造を実現している。これにより、第2の防水部(防水部)が構成される。
Further, as shown in FIG. 1, the second labyrinth portion 29 (labyrinth portion 29) includes a second rib 30 (rib 30) extending a part of the operation panel 8 downward, and a second rib. A second groove 31 (groove 31) having a substantially U-shaped (including U-shaped) cross-sectional shape formed on substantially the entire circumference of the outer peripheral end portion constituting the recess 13a of the protective case 13 holding the 30; It is composed of Then, the second rib 30 (rib 30) and the second groove 31 (groove 31) are designed to have a narrow gap so that the second labyrinth portion 29 (labyrinth portion 29) is formed. A waterproof structure in which water does not easily enter the protective case 13 is realized. Thereby, a 2nd waterproof part (waterproof part) is comprised.
なお、第2のラビリンス部29(ラビリンス部29)は、第2のリブ30(リブ30)と第2の溝31(溝31)の一部が当接する構造でもよく、同様の効果を得ることができる。
The second labyrinth portion 29 (labyrinth portion 29) may have a structure in which the second rib 30 (rib 30) and a part of the second groove 31 (groove 31) are in contact with each other, and obtain the same effect. Can do.
このとき、図1、図3および図5に示すように、マイクロコンピュータ20を装着した電源基板11と、保護ケース13に装着した電源スイッチ19は、第1のラビリンス部17の内側(収容部5内)で、第2のラビリンス部29(ラビリンス部29)で防水される区域の外側の収容部5内に装着されている。そして、電源スイッチ19を商用電源に接続するためのリード線19aが引き出される電源スイッチポッティング部44は、例えばエポキシ樹脂などで部分的にポッティング処理される。これにより、電源スイッチ19は、外部から浸入する水に対して防水される。また、電源基板11と電源スイッチ19とを接続するリード線19aは、電源基板11に電気的に接続されるとともに、電源基板11を被覆するポッティング剤24で防水されている。
At this time, as shown in FIGS. 1, 3, and 5, the power supply board 11 on which the microcomputer 20 is mounted and the power switch 19 mounted on the protective case 13 are connected to the inside of the first labyrinth section 17 (the housing section 5 The inner part 5 is mounted in the accommodating part 5 outside the area to be waterproofed by the second labyrinth part 29 (labyrinth part 29). Then, the power switch potting portion 44 from which the lead wire 19a for connecting the power switch 19 to the commercial power source is drawn is partially potted with, for example, epoxy resin. Thereby, the power switch 19 is waterproofed against water entering from the outside. The lead wire 19 a that connects the power supply substrate 11 and the power switch 19 is electrically connected to the power supply substrate 11 and is waterproofed with a potting agent 24 that covers the power supply substrate 11.
これにより、特に操作基板9を、ポッティング処理せずに、第1のラビリンス部17と第2のラビリンス部29(ラビリンス部29)による簡単な構成で防水できる。
Thereby, the operation board 9 can be waterproofed with a simple configuration by the first labyrinth part 17 and the second labyrinth part 29 (labyrinth part 29) without performing the potting process.
また、本実施の形態では、商用電源に接続され、例えばモータなどの負荷に大電流を流す高電流回路を電源基板11に配置するとともに、例えばLEDなどの表示部6や操作スイッチ10などの低電流回路を操作基板9に配置する。これにより、電源基板11などの高電流回路からなる高電流区域と、操作基板9などの低電流回路からなる低電流区域とを分離して配置できる。その結果、操作パネル8と保護ケース13から形成される第2のラビリンス部29の区域内で、例えば気温低下により結露が生じる場合でも、低電流回路からなる操作基板9をポッティング剤24で充填して防水対策をする必要は、特にない。一方、電源基板11などの高電流回路は、ポッティング剤24を充填して被覆するため、水分などによるショートを容易に、より確実に防止できる。
Further, in the present embodiment, a high current circuit that is connected to a commercial power source and supplies a large current to a load such as a motor is disposed on the power supply substrate 11, and the display unit 6 such as an LED and the operation switch 10 are low. A current circuit is arranged on the operation board 9. As a result, a high current area composed of a high current circuit such as the power supply substrate 11 and a low current area composed of a low current circuit such as the operation substrate 9 can be separated from each other. As a result, in the area of the second labyrinth portion 29 formed from the operation panel 8 and the protective case 13, for example, even when condensation occurs due to a decrease in temperature, the operation substrate 9 composed of a low current circuit is filled with the potting agent 24. There is no particular need for waterproofing. On the other hand, since the high current circuit such as the power supply substrate 11 is filled and covered with the potting agent 24, a short circuit due to moisture or the like can be easily and more reliably prevented.
また、本実施の形態では、操作基板9の縁部のほぼ全周が、第2のリブ30で囲われている。そのため、例え第1のラビリンス部17から収容部5に浸入した水が収容部5に形成した水抜き孔18に向かって流れるときに飛沫を発生する場合でも、第2のラビリンス部29で囲われた操作基板9の区域内への飛沫の浸入を防止できる。さらに、収容部5に形成した水抜き孔18から、例えば昆虫などの異物が収容部5の中に入ってきた場合でも、第2のラビリンス部29(ラビリンス部29)で囲われた操作基板9の区域内への異物の浸入を防止できる。その結果、水分や異物などの浸入による操作基板9のショートを防いで、洗濯機の誤動作などを防止できる。
In the present embodiment, almost the entire circumference of the edge of the operation substrate 9 is surrounded by the second rib 30. For this reason, even when water that has entered the housing portion 5 from the first labyrinth portion 17 flows toward the drain hole 18 formed in the housing portion 5, it is surrounded by the second labyrinth portion 29. Intrusion of splash into the area of the operation substrate 9 can be prevented. Furthermore, even when a foreign substance such as an insect enters the storage unit 5 from the drain hole 18 formed in the storage unit 5, the operation substrate 9 surrounded by the second labyrinth unit 29 (labyrinth unit 29). Intrusion of foreign matter into the area can be prevented. As a result, it is possible to prevent the operation board 9 from being short-circuited due to intrusion of moisture or foreign matter, and prevent malfunction of the washing machine.
また、本実施の形態では、図2に示すように、操作装置50を構成する操作基板9と電源基板11とは、フラットケーブル32などで電気的に接続される。そこで、フラットケーブル32を引き出すために、操作基板9の外周に沿ってほぼ全周を覆う第2のリブ30(リブ30)の一部を切り欠いて、フラットケーブル引き出し口33を形成する必要がある。このとき、通常、フラットケーブル引き出し口33は、衣類投入口4の反対側、保護ケース13が下方に傾斜している洗濯機の正面側に設ける。これにより、水は自重により下方に流れるので、上方に配置された操作基板9側への水の浸入を防止できる。さらに、フラットケーブル32に、例えば独立気泡構造を有する発泡ゴムシートからなるシール材34を巻きつけて、フラットケーブル引き出し口33との間の隙間を塞ぐ構成とする。これにより、シール材34で、第2のリブ30(リブ30)の切り欠き部であるフラットケーブル引き出し口33を隙間なく塞ぐことができる。その結果、フラットケーブル引き出し口33を介して、水分が操作基板9に浸入することを防止できる。つまり、第2のリブ30(リブ30)の一部に切り欠き部を設けても、操作基板9の外周に沿って、第2のリブ30(リブ30)が全周を覆って設けられていることと同様の効果を得ることができる。その結果、信頼性に優れた電源装置60を有する操作装置50および洗濯機を実現できる。
Further, in the present embodiment, as shown in FIG. 2, the operation board 9 and the power supply board 11 constituting the operation device 50 are electrically connected by a flat cable 32 or the like. Therefore, in order to pull out the flat cable 32, it is necessary to cut out a part of the second rib 30 (rib 30) covering almost the entire circumference along the outer periphery of the operation board 9 to form the flat cable outlet 33. is there. At this time, the flat cable outlet 33 is usually provided on the opposite side of the clothes insertion port 4 and on the front side of the washing machine in which the protective case 13 is inclined downward. Thereby, since water flows downward by its own weight, it is possible to prevent water from entering the operation substrate 9 disposed above. Further, a sealing material 34 made of, for example, a foamed rubber sheet having a closed cell structure is wound around the flat cable 32 to close a gap between the flat cable 32 and the flat cable outlet 33. Thereby, the flat cable lead-out port 33 which is a notch part of the 2nd rib 30 (rib 30) can be plugged up with the sealing material 34 without gap. As a result, moisture can be prevented from entering the operation board 9 through the flat cable outlet 33. That is, even if the notch is provided in a part of the second rib 30 (rib 30), the second rib 30 (rib 30) is provided so as to cover the entire circumference along the outer periphery of the operation substrate 9. It is possible to obtain the same effect as being present. As a result, the operation device 50 and the washing machine having the power supply device 60 with excellent reliability can be realized.
また、本実施の形態では、図1、図4および図5に示すように、操作パネル取り付け面28は、衣類投入口4側の第1のラビリンス部17の一部に構成される堰部17aの第1の溝26の一部を切り欠いて設けられる。そのため、衣類投入口4側の第1の溝26において、操作パネル取り付け面28が第1の溝26の最下点となる。
Moreover, in this Embodiment, as shown in FIG.1, FIG4 and FIG.5, the operation panel attachment surface 28 is the dam part 17a comprised in a part of 1st labyrinth part 17 by the side of the clothing insertion port 4. A part of the first groove 26 is cut out. Therefore, the operation panel attachment surface 28 is the lowest point of the first groove 26 in the first groove 26 on the clothing insertion port 4 side.
そこで、第1の溝26の最下点である操作パネル取り付け面28を、第2のラビリンス部29を構成する第2の溝31の最上点31a(通常、衣類投入口4側の第2の溝31の位置に相当)の高さよりも低い位置に形成している。
Therefore, the operation panel mounting surface 28, which is the lowest point of the first groove 26, is connected to the uppermost point 31a of the second groove 31 that constitutes the second labyrinth portion 29 (usually the second point on the clothing inlet 4 side). It is formed at a position lower than the height (corresponding to the position of the groove 31).
つまり、高さが、第1の溝26の上端26a、第2の溝31の最上点31a(上端31a)、第1の溝26の一部に設けられた操作パネル取り付け面28、水抜き孔18の順に低くなるように構成する。また、衣類投入口4から、上部外郭3の正面側に向かって、第1のラビリンス部17の堰部17a、第2のラビリンス部29、操作基板9、フラットケーブル引き出し口33の順に遠くなるように構成する。
That is, the height is the upper end 26 a of the first groove 26, the uppermost point 31 a (upper end 31 a) of the second groove 31, the operation panel mounting surface 28 provided at a part of the first groove 26, and the drain hole. It is configured to be lower in the order of 18. Further, the weir portion 17 a of the first labyrinth portion 17, the second labyrinth portion 29, the operation board 9, and the flat cable lead-out port 33 are arranged in this order from the clothing insertion port 4 toward the front side of the upper shell 3. Configure.
これにより、例えば衣類投入口4から、第1の防水部を構成する第1のラビリンス部17の堰部17aを超えて水が浸入した場合、操作パネル取り付け面28が第1の溝26の最下点であるので、操作パネル取り付け面28の部分からのみ、水が収容部5に浸入して流れる。そのため、第1の溝26の最上点26a(上端26a)からは、水が浸入しない。この場合、操作パネル取り付け面28の部分から浸入した水の流れにより飛沫が発生しても、操作パネル取り付け面28より第2の溝31の最上点31aが高いので、操作基板9の区域内への水の浸入を防ぐことができる。
As a result, for example, when water enters from the clothes insertion port 4 beyond the weir portion 17a of the first labyrinth portion 17 constituting the first waterproof portion, the operation panel mounting surface 28 is positioned at the outermost portion of the first groove 26. Since it is a lower point, water enters the storage portion 5 and flows only from the portion of the operation panel mounting surface 28. Therefore, water does not enter from the uppermost point 26a (the upper end 26a) of the first groove 26. In this case, even if splashing occurs due to the flow of water that has entered from the portion of the operation panel mounting surface 28, the uppermost point 31 a of the second groove 31 is higher than the operation panel mounting surface 28, so Can prevent the ingress of water.
以上で説明したように、本実施の形態によれば、操作基板9への水の浸入を、第1の防水部を構成する堰部17aを有する第1のラビリンス部17と、第2の防水部(防水部)である第2のラビリンス部29(ラビリンス部29)の2重構造により防ぐことができる。そのため、操作基板9をポッティング剤24で被覆して防水する必要がなくなる。これにより、操作基板9は、ポッティング剤24による熱ストレスや収縮による機械的ストレスを受けることがないので、操作基板9などの部品の反りを抑制できる。その結果、操作パネル8と操作基板9との位置ずれや、操作パネル8に装着した操作ボタン7および表示部6と、操作基板9に装着した操作スイッチ10との相対的な位置を安定にできる。さらに、使用者が操作ボタン7を操作したときのストロークのばらつきを抑え、操作力を安定化できる。
As described above, according to the present embodiment, the first labyrinth part 17 having the weir part 17a that constitutes the first waterproof part and the second waterproof part are intruded into the operation substrate 9. This can be prevented by the double structure of the second labyrinth part 29 (labyrinth part 29) which is a part (waterproof part). Therefore, it is not necessary to waterproof the operation substrate 9 by covering it with the potting agent 24. Thereby, since the operation board 9 does not receive the thermal stress by the potting agent 24 or the mechanical stress by shrinkage | contraction, the curvature of components, such as the operation board 9, can be suppressed. As a result, the positional deviation between the operation panel 8 and the operation board 9 and the relative position between the operation button 7 and the display unit 6 attached to the operation panel 8 and the operation switch 10 attached to the operation board 9 can be stabilized. . Furthermore, the variation in stroke when the user operates the operation button 7 can be suppressed, and the operation force can be stabilized.
また、本実施の形態によれば、図5と図6に示すように、内槽1および水槽40の上方は、例えば円形形状に開放され、水槽40の開放部である上端には、例えばリング状の水受け槽カバー35(以下、「水槽カバー」と記す)が装着されている。このとき、第1の防水部を構成する水抜き孔18を、水槽カバー35の上方で、かつ水槽カバー35の略円縁部(円縁部を含む)より、外側の領域に配置している。つまり、水抜き孔18から排水される水が、水槽カバー35および内槽1の範囲には滴下しない構成としている。
Moreover, according to this Embodiment, as shown in FIG. 5 and FIG. 6, the upper part of the inner tank 1 and the water tank 40 is open | released, for example in circular shape, and a ring is formed in the upper end which is the open part of the water tank 40, for example. A water tank cover 35 (hereinafter referred to as “water tank cover”) is attached. At this time, the drain hole 18 constituting the first waterproof part is disposed above the water tank cover 35 and in a region outside the substantially circular edge part (including the circular edge part) of the water tank cover 35. . That is, the water drained from the drain hole 18 is configured not to drop into the range of the water tank cover 35 and the inner tank 1.
この構成によれば、例えば洗濯中に内槽1で発生した泡が、水槽カバー35を超えて溢れ出した場合、水抜き孔18に到達する前に、洗濯機本体2の下方に落下する。これにより、水抜き孔18から収容部5内への泡の浸入を防止して、保護ケース13と操作パネル8との隙間などから操作基板9の区域内に泡が浸入することを防ぐことができる。その結果、操作基板9の回路のショートを未然に防いで、洗濯機の誤動作や誤表示などを防止できる。
According to this configuration, for example, when foam generated in the inner tub 1 overflows beyond the water tank cover 35 during washing, it falls below the washing machine main body 2 before reaching the drain hole 18. Thereby, it is possible to prevent the invasion of bubbles from the drain hole 18 into the accommodating portion 5 and to prevent the intrusion of bubbles into the area of the operation substrate 9 from the gap between the protective case 13 and the operation panel 8. it can. As a result, it is possible to prevent the operation board 9 from being short-circuited, and prevent malfunctions and erroneous display of the washing machine.
また、図1と図6に示すように、水抜き孔18は、例えば略45度(45度を含む)の角度で、内槽1とは反対側(外周側)の下方、すなわち正面側下方に向かって開口して形成される。これにより、収容部5に浸入した水は、収容部5の底部5aに溜まる前に、効率よく排水される。さらに、内槽1から発生した洗剤成分を含む泡が水槽カバー35から溢れて乗り越え、収容部5の裏面5bを伝わる場合でも、水抜き孔18の傾斜面によって泡を下方に誘導することができる。その結果、収容部5内への泡の浸入を、効果的に防止できる。
As shown in FIGS. 1 and 6, the drain hole 18 is, for example, at an angle of approximately 45 degrees (including 45 degrees), below the inner tank 1 (outer peripheral side), that is, below the front side. It is formed to open toward. As a result, the water that has entered the housing part 5 is efficiently drained before it collects in the bottom part 5a of the housing part 5. Furthermore, even when the foam containing the detergent component generated from the inner tank 1 overflows from the water tank cover 35 and travels through the back surface 5b of the housing portion 5, the foam can be guided downward by the inclined surface of the drain hole 18. . As a result, it is possible to effectively prevent bubbles from entering the housing portion 5.
また、本実施の形態では、第1の防水部を構成する第1のラビリンス部17の堰部17aにおいて、第1のリブ25と第1の溝26との間、および操作パネル8と操作パネル取り付け面28との間に、操作パネル取り付け面28と嵌合する操作パネル8の嵌合部が着脱できるように設計隙間を設けている。そのため、衣類投入口4を介して衣類を出し入れするときに、設計隙間から水が浸入することになる。そこで、設計隙間の総断面積S1に対して、水抜き孔18の開口面積に相当する総断面積S2(以下、「面積S2」と略記する)が大きくなるように設計隙間を設計して形成している。なお、設計隙間の総断面積S1とは、第1のラビリンス部17の堰部17aを、環状に構成された第1のラビリンス部17の周方向に切断した場合の断面積の総和である。また、以下では、浸入する水が通流する設計隙間の総断面積S1を、堰部17aの面積S1と略記する。
Moreover, in this Embodiment, in the dam part 17a of the 1st labyrinth part 17 which comprises a 1st waterproof part, between the 1st rib 25 and the 1st groove | channel 26, and the operation panel 8 and the operation panel A design gap is provided between the attachment surface 28 and the fitting portion of the operation panel 8 that fits the operation panel attachment surface 28 so that the fitting portion can be attached and detached. Therefore, when clothes are taken in and out through the clothes insertion port 4, water enters from the design gap. Therefore, the design gap is designed and formed so that the total cross-sectional area S2 corresponding to the opening area of the drain hole 18 (hereinafter abbreviated as “area S2”) is larger than the total cross-sectional area S1 of the design gap. is doing. The total cross-sectional area S1 of the design gap is the total cross-sectional area when the weir portion 17a of the first labyrinth portion 17 is cut in the circumferential direction of the first labyrinth portion 17 configured in an annular shape. Hereinafter, the total cross-sectional area S1 of the design gap through which the entering water flows is abbreviated as the area S1 of the weir portion 17a.
以下に、水抜き孔18の面積S2を、堰部17aの面積S1より大きくする理由について、図7を用いて、具体的に説明する。
Hereinafter, the reason why the area S2 of the drain hole 18 is made larger than the area S1 of the weir part 17a will be specifically described with reference to FIG.
図7は、本実施の形態の洗濯機における堰部の構成と相対的な配置関係を説明する要部断面図である。なお、図7の左図は、堰部17aの操作パネル取り付け面28近傍の断面を示している。また、図7の右図は、第1のラビリンス部17を構成する堰部17aの断面を示している。
FIG. 7 is a cross-sectional view of an essential part for explaining the configuration of the weir portion and the relative positional relationship in the washing machine according to the present embodiment. In addition, the left figure of FIG. 7 has shown the cross section of the operation panel attachment surface 28 vicinity of the dam part 17a. Moreover, the right figure of FIG. 7 has shown the cross section of the dam part 17a which comprises the 1st labyrinth part 17. As shown in FIG.
図7に示すように、まず、第1のラビリンス部17の堰部17aを構成する第1のリブ25と第1の溝26との間を流れる水流(図7右図中の矢印)に対して垂直な面の面積をS01とする。また、操作パネル8と操作パネル取り付け面28との間を流れる水流(図7左図中の矢印)に対する垂直な面の面積をS02とする。そして、図7に示すように、第1の溝26の上端26aと操作パネル取り付け面28との高さの差をh01とする。なお、面積S01と面積S02の和が、堰部17aの面積S1に相当する。
As shown in FIG. 7, first, with respect to the water flow (arrow in the right figure of FIG. 7) which flows between the 1st rib 25 which comprises the dam part 17a of the 1st labyrinth part 17, and the 1st groove | channel 26. The area of the vertical surface is S01. Further, the area of the surface perpendicular to the water flow (arrow in the left diagram of FIG. 7) flowing between the operation panel 8 and the operation panel mounting surface 28 is S02. Then, as shown in FIG. 7, the difference in height between the upper end 26a of the first groove 26 and the operation panel mounting surface 28 is defined as h01. The sum of the area S01 and the area S02 corresponds to the area S1 of the dam portion 17a.
このとき、流量Q02の水が、(数2)を満たす場合、面積S01の第1のリブ25と第1の溝26との間から、収容部5内に流れ出すことになる。
At this time, when the water having the flow rate Q02 satisfies (Equation 2), the water flows out from the space between the first rib 25 and the first groove 26 having the area S01 into the accommodating portion 5.
(数2)
Q02>S02×√(2・g・h01) (2) (Equation 2)
Q02> S02 × √ (2 · g · h01) (2)
Q02>S02×√(2・g・h01) (2) (Equation 2)
Q02> S02 × √ (2 · g · h01) (2)
しかし、面積S01を流れる水の流速は、操作パネル取り付け面28よりも高さh01ほど高い分、面積S02を流れる水の流速より遅くなる。
However, the flow velocity of the water flowing through the area S01 is slower than the flow velocity of the water flowing through the area S02 by the height h01 higher than the operation panel mounting surface 28.
さらに、本実施の形態では、面積S01と面積S02とを合計した堰部17aの面積S1よりも、水抜き孔18を流れる水流に垂直な面の面積S2を大きくしている。そのため、収容部5に流れ込む流量をQ1とした場合、堰部17aの面積S1を流れる水の流速V1は、(数3)で表される。一方、収容部5から排水される流量をQ2とした場合、水抜き孔18の面積S2を流れる流速V2は、(数4)で表される。
Furthermore, in the present embodiment, the area S2 of the surface perpendicular to the water flow through the drain hole 18 is made larger than the area S1 of the weir portion 17a that is the sum of the areas S01 and S02. Therefore, when the flow rate flowing into the accommodating portion 5 is Q1, the flow velocity V1 of the water flowing through the area S1 of the weir portion 17a is expressed by (Equation 3). On the other hand, when the flow rate drained from the storage unit 5 is Q2, the flow velocity V2 flowing through the area S2 of the drain hole 18 is expressed by (Equation 4).
(数3)
V1=Q1/S1 (3) (Equation 3)
V1 = Q1 / S1 (3)
V1=Q1/S1 (3) (Equation 3)
V1 = Q1 / S1 (3)
(数4)
V2=Q2/S2 (4) (Equation 4)
V2 = Q2 / S2 (4)
V2=Q2/S2 (4) (Equation 4)
V2 = Q2 / S2 (4)
そして、堰部17aの面積S1から収容部5に流れ込む水の量が、すべて水抜き孔18の面積S2からのみ排水されるとすると、Q1=Q2となる。しかし、本実施の形態では、S1<S2となるように設計しているので、堰部17aの面積S1を流れる水の流速V1と、水抜き孔18の面積S2を流れる流速V2とは、(数5)に示す関係となる。
If the amount of water flowing from the area S1 of the weir part 17a into the accommodating part 5 is drained only from the area S2 of the drain hole 18, Q1 = Q2. However, since the present embodiment is designed so that S1 <S2, the flow velocity V1 of the water flowing through the area S1 of the weir portion 17a and the flow velocity V2 flowing through the area S2 of the drain hole 18 are ( The relationship shown in Equation 5) is obtained.
(数5)
V1>V2 (5) (Equation 5)
V1> V2 (5)
V1>V2 (5) (Equation 5)
V1> V2 (5)
また、堰部17a面積S1を流れる水の流速V1は、堰部17aの流入部の水位をH1(操作パネル取り付け面28からの高さに相当)とすると、(数6)で表される。
Further, the flow velocity V1 of the water flowing through the dam portion 17a area S1 is expressed by (Expression 6) when the water level of the inflow portion of the dam portion 17a is H1 (corresponding to the height from the operation panel mounting surface 28).
(数6)
V1=√(2・g・H1) (6) (Equation 6)
V1 = √ (2 · g · H1) (6)
V1=√(2・g・H1) (6) (Equation 6)
V1 = √ (2 · g · H1) (6)
同様に、水抜き孔18の面積S2を流れる水の流速V2は、収容部5の底部の流入部の水位をH2(操作パネル取り付け面28からの高さに相当)とすると、(数7)で表される。
Similarly, the flow velocity V2 of the water flowing through the area S2 of the drain hole 18 is expressed by the following equation (7) when the water level at the inflow portion at the bottom of the housing portion 5 is H2 (corresponding to the height from the operation panel mounting surface 28) It is represented by
(数7)
V2=√(2・g・H2) (7) (Equation 7)
V2 = √ (2 · g · H2) (7)
V2=√(2・g・H2) (7) (Equation 7)
V2 = √ (2 · g · H2) (7)
そのため、(数5)から、水位H1と水位H2とは、(数8)に示す関係となる。
Therefore, from (Equation 5), the water level H1 and the water level H2 have the relationship shown in (Equation 8).
(数8)
H1>H2 (8) (Equation 8)
H1> H2 (8)
H1>H2 (8) (Equation 8)
H1> H2 (8)
つまり、堰部17aの面積S1よりも、水抜き孔18の面積S2を大きくすると、第1のラビリンス部17の堰部17aを流れる水の水位H1に比べて、収容部5内に溜まる水の水位H2が必ず低くなる。これにより、収容部5に浸入する水を、水抜き孔18を介して確実に排水できる。その結果、操作基板9への水の浸入を確実に防止できる。
That is, when the area S2 of the drain hole 18 is made larger than the area S1 of the dam portion 17a, the water accumulated in the accommodating portion 5 is larger than the water level H1 of the water flowing through the dam portion 17a of the first labyrinth portion 17. The water level H2 is always low. As a result, the water that enters the housing portion 5 can be reliably drained through the drain hole 18. As a result, water can be reliably prevented from entering the operation substrate 9.
一方、もし、なんらかの原因により水位H1と水位H2とが同じ高さになった場合でも、(数6)と(数7)から、堰部17aの面積S1を流れる水の流速V1と、水抜き孔18の面積S2を流れる流速V2とは、(数9)に示す関係となる。
On the other hand, even if the water level H1 and the water level H2 become the same height for some reason, from (Equation 6) and (Equation 7), the flow velocity V1 of the water flowing through the area S1 of the weir portion 17a and the water drain The flow velocity V2 flowing through the area S2 of the hole 18 has the relationship shown in (Equation 9).
(数9)
V1=V2 (9) (Equation 9)
V1 = V2 (9)
V1=V2 (9) (Equation 9)
V1 = V2 (9)
しかし、本実施の形態では、S1<S2となるように設計している。そのため、(数3)と(数4)から、収容部5に流れ込む流量Q1と、収容部5から排水される流量Q2との関係は、(数10)で表される。
However, in this embodiment, the design is such that S1 <S2. Therefore, from (Equation 3) and (Equation 4), the relationship between the flow rate Q1 flowing into the storage unit 5 and the flow rate Q2 discharged from the storage unit 5 is expressed by (Equation 10).
(数10)
Q1<Q2 (10) (Equation 10)
Q1 <Q2 (10)
Q1<Q2 (10) (Equation 10)
Q1 <Q2 (10)
つまり、(数10)からわかるように、収容部5に流入する流量Q1より、水抜き孔18から排水される流量Q2が大きくなる。そのため、収容部5の内部の水位H2は、すぐに低くなる。これにより、水抜き孔18から単位時間あたりに排出できる水量は、第1のラビリンス部17の堰部17aから浸入できる水量よりも多くなる。その結果、仮に水位H1と水位H2とが同じ高さになる場合でも、水抜き孔18から効果的に排水して、操作基板9への水の浸入を確実に効率的に防止できる。
That is, as can be seen from (Equation 10), the flow rate Q2 drained from the drain hole 18 is larger than the flow rate Q1 flowing into the accommodating portion 5. Therefore, the water level H2 inside the accommodating part 5 becomes low immediately. As a result, the amount of water that can be discharged from the drain hole 18 per unit time is greater than the amount of water that can enter from the weir portion 17a of the first labyrinth portion 17. As a result, even if the water level H1 and the water level H2 are the same height, the water can be effectively drained from the drain hole 18 to reliably prevent water from entering the operation substrate 9.
また、本実施の形態では、図7に示すように、第1の防水部を構成する第1のラビリンス部17の堰部17aにおいて、第1のリブ25が第1の溝26に狭持される部分の長さL(高さ方向の長さ)は、第1の溝26の幅W(断面の幅)よりも長くする。これにより、第1の防水部の堰部17aを通り抜けようとする水の通路を狭くするとともに、長くすることにより水を溜める空間を増加させて、防水性能を高くできる。
Further, in the present embodiment, as shown in FIG. 7, the first rib 25 is sandwiched by the first groove 26 in the dam portion 17 a of the first labyrinth portion 17 constituting the first waterproof portion. The length L (the length in the height direction) of the portion is longer than the width W (cross-sectional width) of the first groove 26. Thereby, while narrowing the channel | path of the water which tries to pass through the dam part 17a of a 1st waterproof part, the space which stores water can be increased by lengthening, and waterproof performance can be made high.
同様に、第2の防水部(防水部)の第2のラビリンス部29(ラビリンス部29)を構成する第2のリブ30(リブ30)が第2の溝31(溝31)に狭持される部分の長さ(高さ方向の長さ)は、第2の溝31の幅(断面の幅)よりも長くする。これにより、第2の防水部(防水部)を通り抜けようとする水の通路を狭くするとともに、長くすることにより水を溜める空間を増加させて、防水性能を高くできる。
Similarly, the 2nd rib 30 (rib 30) which constitutes the 2nd labyrinth part 29 (labyrinth part 29) of the 2nd waterproof part (waterproof part) is pinched by the 2nd groove 31 (groove 31). The length of the portion (the length in the height direction) is made longer than the width of the second groove 31 (the width of the cross section). Thereby, while narrowing the channel | path of the water which tries to pass through a 2nd waterproof part (waterproof part), and making it long, the space which stores water can be increased, and waterproof performance can be made high.
以上で説明したように、本実施の形態によれば、第1のラビリンス部17の堰部17aをラビリンス構造とすることにより、第1のリブ25と第1の溝26との設計隙間を流れる水の流路を、コンパクトな構成のままで狭く、また長くできる。そのため、第1のラビリンス部17の堰部17aを流れる流量を少なくして、操作基板9への水の浸入を効率よく防止できる。
As described above, according to the present embodiment, the weir portion 17a of the first labyrinth portion 17 has a labyrinth structure so that the design gap between the first rib 25 and the first groove 26 flows. The water flow path can be narrowed and lengthened with a compact configuration. For this reason, the flow rate of the first labyrinth portion 17 flowing through the weir portion 17a can be reduced, and water can be efficiently prevented from entering the operation substrate 9.
また、本実施の形態によれば、操作パネル8や収容部5などを構成する部品の加工ばらつきなどにより、操作パネル8の第1のリブ25の位置が、例えば洗濯機本体2前方(図1の左側)にずれた場合でも、第1のリブ25と、第1の溝26の洗濯機本体2の前方側との隙間が狭くなる。そのため、第1のラビリンス部17の堰部17aを介して、収容部5への水の浸入を、より防止できるので、操作基板9への防水効果が低下することはない。同様に、操作パネル8の第1のリブ25の位置が、例えば洗濯機本体2後方(図1の右側)にずれた場合でも、洗濯機本体2の後方側の隙間が狭くなる。そのため、上記と同様の効果が得られる。つまり、ラビリンス構造により収容部5への水の浸入を効果的に防ぐことができる。その結果、第2のラビリンス部29(ラビリンス部29)で囲われている操作基板9を防水できる。
In addition, according to the present embodiment, the position of the first rib 25 of the operation panel 8 is, for example, the front of the washing machine main body 2 (FIG. 1) due to processing variations of parts constituting the operation panel 8 and the housing 5 and the like. Even when it is shifted to the left), the gap between the first rib 25 and the front side of the washing machine body 2 of the first groove 26 is narrowed. For this reason, water can be prevented from entering the housing portion 5 via the weir portion 17a of the first labyrinth portion 17, so that the waterproof effect on the operation substrate 9 is not lowered. Similarly, even when the position of the first rib 25 of the operation panel 8 is shifted to the rear of the washing machine body 2 (right side in FIG. 1), for example, the gap on the rear side of the washing machine body 2 is narrowed. Therefore, the same effect as described above can be obtained. That is, the labyrinth structure can effectively prevent water from entering the housing portion 5. As a result, the operation board 9 surrounded by the second labyrinth part 29 (labyrinth part 29) can be waterproofed.
また、本実施の形態によれば、第1の防水部を構成する第1のラビリンス部17の堰部17aと水抜き孔18により、収容部5内に浸入した水を、収容部5内に溜まりにくくできる。さらに、第2の防水部を構成する第2のラビリンス部29(ラビリンス部29)により、第1のラビリンス部17の堰部17aから入った水が流れるときに発生する飛散した水分や、水抜き孔18から入ってくる水蒸気や昆虫などの異物の操作基板9への浸入を防止できる。その結果、操作基板9をポッティング剤24の充填により被覆して防水する必要がない。
Moreover, according to this Embodiment, the water which infiltrated into the accommodating part 5 with the dam part 17a and the drain hole 18 of the 1st labyrinth part 17 which comprises a 1st waterproof part is contained in the accommodating part 5. It can be hard to collect. Further, the second labyrinth part 29 (labyrinth part 29) constituting the second waterproof part causes scattered water generated when water entered from the weir part 17a of the first labyrinth part 17 flows, or drains water. Intrusion of foreign matter such as water vapor and insects entering through the hole 18 into the operation substrate 9 can be prevented. As a result, the operation substrate 9 need not be waterproofed by being covered with the potting agent 24.
さらに、操作基板9は、ポッティング剤24による熱ストレスや収縮による機械的ストレスを受けることがないので、操作基板9などの部品の反りを抑制できる。これにより、操作パネル8と操作基板9との位置ずれや、操作パネル8に装着した操作ボタン7および表示部6と、操作基板9に装着した操作スイッチ10との相対的な位置を安定にできる。その結果、使用者が操作ボタン7を操作したときのストロークのばらつきを抑え、操作力を安定させることができる。
Furthermore, since the operation substrate 9 is not subjected to thermal stress due to the potting agent 24 or mechanical stress due to contraction, warping of components such as the operation substrate 9 can be suppressed. As a result, the positional deviation between the operation panel 8 and the operation board 9 and the relative position between the operation button 7 and the display unit 6 attached to the operation panel 8 and the operation switch 10 attached to the operation board 9 can be stabilized. . As a result, variation in stroke when the user operates the operation button 7 can be suppressed, and the operation force can be stabilized.
具体的に説明すると、従来の洗濯機の場合、操作基板9をポッティング剤24で被覆すると、操作基板や保護ケースが反るので、例えば操作ボタン7の操作力を強くする必要があるなど、操作性に課題があった。そのため、図1に示すように、例えば操作ボタン7と操作スイッチ10との隙間g2を小さく(狭く)して、操作力を軽くする必要がある。しかし、隙間g2を狭くすると、使用者が、例えば洗濯機に寄りかかるなどして、誤って操作パネル8の操作ボタン7部近傍に力を加えると、意識的に操作ボタン7を押さなくても、操作スイッチ10が押された状態になるなど、誤動作を誘引しやすかった。
Specifically, in the case of a conventional washing machine, if the operation board 9 is covered with the potting agent 24, the operation board and the protective case are warped. For example, the operation force of the operation button 7 needs to be increased. There was a problem with sex. Therefore, as shown in FIG. 1, for example, it is necessary to reduce (narrow) the gap g2 between the operation button 7 and the operation switch 10 to reduce the operation force. However, when the gap g2 is narrowed, if the user accidentally applies a force in the vicinity of the operation button 7 portion of the operation panel 8, for example, leaning on the washing machine, the user does not need to consciously press the operation button 7. It was easy to induce malfunctions, such as the operation switch 10 being pressed.
そこで、本実施の形態によれば、図2に示すように、操作基板9をポッティング剤24で充填して被覆せず、例えば操作基板9を操作スイッチ10近傍で、操作パネル8の操作基板取り付けボス14と操作基板取り付けビス15とにより、操作パネル8に直接固定する。これにより、操作基板9にポッティング剤で被覆しないので、操作基板9の変形を防止できるとともに、操作基板9を操作パネル8に直接固定しやすくなる。さらに、直接固定することにより、操作パネル8の操作ボタン7と、操作基板9の操作スイッチ10との位置ずれを生じにくくできる。その結果、操作ボタン7と操作スイッチ10との寸法や位置関係を安定させることにより、操作スイッチ10への操作力のばらつきを抑制して誤動作を低減できる。
Therefore, according to the present embodiment, as shown in FIG. 2, the operation board 9 is not filled and covered with the potting agent 24. For example, the operation board 9 is mounted near the operation switch 10 and the operation board 8 is attached to the operation panel 8. The boss 14 and the operation board mounting screw 15 are directly fixed to the operation panel 8. Thereby, since the operation substrate 9 is not covered with the potting agent, the deformation of the operation substrate 9 can be prevented and the operation substrate 9 can be easily fixed directly to the operation panel 8. Further, by directly fixing, it is possible to make it difficult for the operation button 7 on the operation panel 8 and the operation switch 10 on the operation board 9 to be displaced. As a result, by stabilizing the dimensions and positional relationship between the operation button 7 and the operation switch 10, it is possible to suppress variations in operation force on the operation switch 10 and reduce malfunctions.
また、本実施の形態によれば、端子間ピッチが狭くわずかな水分で誤動作しやすいマイクロコンピュータ20と、商用電源に接続され、トラッキング防止のために防水が必要な電源スイッチ19とは、操作基板9に装着せず、保護ケース13で分離された配置された電源基板11に装着してポッティング剤24で被覆する。そのため、マイクロコンピュータ20や電源スイッチ19を操作基板9に装着しないので、操作基板9をポッティング剤24で防水しなくても、誤動作やトラッキングの発生を容易に防止できる。
In addition, according to the present embodiment, the microcomputer 20 that has a narrow pitch between terminals and is likely to malfunction due to slight moisture, and the power switch 19 that is connected to a commercial power supply and needs to be waterproofed to prevent tracking are an operation board. It is not attached to 9 but attached to the power supply substrate 11 arranged separated by the protective case 13 and covered with the potting agent 24. Therefore, since the microcomputer 20 and the power switch 19 are not attached to the operation board 9, even if the operation board 9 is not waterproofed with the potting agent 24, it is possible to easily prevent malfunction and tracking.
さらに、本実施の形態によれば、電源基板11をポッティング剤24で被覆し、電源基板11とフラットケーブル32で接続した操作基板9をポッティング剤24で被覆する必要がない。そのため、保護ケース13に収納された操作基板9と電源基板11のうち、電源基板11のみをポッティング剤24で被覆すればよい。その結果、製造が簡単になるとともに、収容部5の中に、操作基板9と電源基板11とを収納する保護ケース13を、コンパクトに収容できる。
Furthermore, according to the present embodiment, it is not necessary to cover the power supply substrate 11 with the potting agent 24 and cover the operation substrate 9 connected to the power supply substrate 11 with the flat cable 32 with the potting agent 24. Therefore, it is only necessary to cover only the power supply board 11 with the potting agent 24 among the operation board 9 and the power supply board 11 accommodated in the protective case 13. As a result, the manufacturing is simplified, and the protective case 13 that accommodates the operation board 9 and the power supply board 11 can be accommodated in the accommodating portion 5 in a compact manner.
また、本実施の形態によれば、第1の防水部を構成する第1のラビリンス部17で収容部5に浸入する水の量を制限するとともに、水抜き孔18で排水する。これにより、浸入した水が収容部5に溜まりにくくするとともに、効率よく排水できる。さらに、第2の防水部を構成する第2のラビリンス部29(ラビリンス部29)をラビリンス構造で構成する。これにより、操作基板9へ浸入する水の量を制限することができる。このとき、第2のラビリンス部29(ラビリンス部29)から操作基板9側に水が流れ込んだ場合でも、全周囲に設けられた第2の溝を水が通り、第2のラビリンス部29(ラビリンス部29)の第2のリブ30と第2の溝31の一部で下方向に傾斜して形成したフラットケーブル引き出し口33により、浸入した水を下方向に流して排出できる。その結果、浸入した水は溝を流れ、操作基板9が収容されている区域には水が流れないため、操作基板9側に水が溜まることがないので、操作基板9を効率よく防水できる。
Further, according to the present embodiment, the amount of water that enters the housing portion 5 is limited by the first labyrinth portion 17 constituting the first waterproof portion, and the water is drained by the drain hole 18. This makes it difficult for the water that has entered into the storage portion 5 to accumulate and drains efficiently. Furthermore, the 2nd labyrinth part 29 (labyrinth part 29) which comprises a 2nd waterproof part is comprised by a labyrinth structure. Thereby, the amount of water that enters the operation substrate 9 can be limited. At this time, even when water flows from the second labyrinth portion 29 (labyrinth portion 29) to the operation substrate 9 side, the water passes through the second groove provided on the entire periphery, and the second labyrinth portion 29 (labyrinth portion 29). Part of the second rib 30 and part of the second groove 31 of the portion 29) can infiltrate the infiltrated water downward and drain it through the flat cable outlet 33 formed to be inclined downward. As a result, the infiltrated water flows through the groove, and water does not flow into the area where the operation board 9 is accommodated. Therefore, water does not accumulate on the operation board 9 side, and the operation board 9 can be efficiently waterproofed.
また、本実施の形態によれば、図3に示すように、保護ケース13の電源スイッチ19近傍に操作パネル8と一体成形した電源スイッチ取り付けボス36を設け、電源スイッチ取り付けビス37で保護ケース13を操作パネル8に固定している。このとき、保護ケース13に一体成形された電源スイッチ位置決めピン38(電源スイッチ位置決め部)を、保護ケース13の電源スイッチ19に対応する部位(位置)に設け、電源スイッチ位置決めピン38を電源スイッチ19に開けた穴と嵌合する。これにより、電源スイッチ19の位置ずれを防止できる。
Further, according to the present embodiment, as shown in FIG. 3, the power switch mounting boss 36 integrally formed with the operation panel 8 is provided in the vicinity of the power switch 19 of the protective case 13, and the protective case 13 is provided with the power switch mounting screw 37.

また、本実施に形態によれば、図1に示すように、保護ケース13に一体成形された操作スイッチ位置決めピン39(操作スイッチ位置決め部)を、保護ケース13の操作スイッチ10に対応する部位(位置)に設ける。これにより、操作スイッチ位置決めピン39は、操作スイッチ10近傍の操作基板9と当接する。その結果、使用者が操作ボタン7を押し下げたときに、操作基板9に実装された操作スイッチ10が下方向に移動することを防止できる。さらに、操作スイッチ10に加わる操作力を安定化できる。
In addition, according to the present embodiment, as shown in FIG. 1, the operation switch positioning pin 39 (operation switch positioning portion) formed integrally with the protective case 13 is connected to the portion corresponding to the operation switch 10 of the protective case 13 ( Position). Thereby, the operation switch positioning pin 39 contacts the operation board 9 in the vicinity of the operation switch 10.

Furthermore, the operation force applied to the operation switch 10 can be stabilized.
また、本実施の形態によれば、保護ケース13に電源スイッチ位置決めピン38と操作スイッチ位置決めピン39とを一体成形する。そのため、使用者が操作ボタン7を押し下げたときに、電源スイッチ19や操作スイッチ10の位置がずれない。さらに、操作基板9と保護ケース13とが、操作基板取り付けビス15および電源スイッチ取り付けビス37で、操作パネル8にビス止めされる。そのため、操作パネル8と、操作スイッチ10および電源スイッチ19との距離が、操作パネル8、操作ボタン7および保護ケース13以外の寸法ばらつきの影響を受けない。その結果、操作スイッチ10に加わる操作力を、さらに安定化できる。
Further, according to the present embodiment, the power switch positioning pin 38 and the operation switch positioning pin 39 are integrally formed in the protective case 13. Therefore, when the user depresses the operation button 7, the positions of the power switch 19 and the operation switch 10 do not shift. Further, the operation board 9 and the protective case 13 are screwed to the operation panel 8 with the operation board mounting screw 15 and the power switch mounting screw 37. Therefore, the distance between the operation panel 8 and the operation switch 10 and the power switch 19 is not affected by dimensional variations other than the operation panel 8, the operation button 7, and the protective case 13. As a result, the operation force applied to the operation switch 10 can be further stabilized.
また、本実施の形態によれば、収容部5、操作パネル8および保護ケース13の少なくともいずれか一つは、例えば難燃ABS樹脂などの難燃性樹脂で成形する。これにより、例え電源基板11が故障した場合でも、製品外への類焼などを防止できる。
In addition, according to the present embodiment, at least one of the accommodating portion 5, the operation panel 8, and the protective case 13 is formed of a flame retardant resin such as a flame retardant ABS resin. Thereby, even when the power supply board 11 breaks down, it is possible to prevent burning out of the product.
なお、本実施の形態では、耐熱材からなる第1の不燃カバー21と第2の不燃カバー23とが金属板から構成される例で説明したが、これに限られない。例えば、第1の不燃カバー21または第2の不燃カバー23のいずれか一つを、例えばABS樹脂などの難燃材料や、マイカなどの不燃材料で構成してもよい。これにより、洗濯機を製造する際に、組み立てなどの作業の順番に対する制約がなくなるため、設計が容易になる。
In the present embodiment, the first incombustible cover 21 and the second incombustible cover 23 made of a heat-resistant material have been described as being configured from a metal plate, but the present invention is not limited to this. For example, any one of the first incombustible cover 21 or the second incombustible cover 23 may be configured of a flame retardant material such as ABS resin or a non-flammable material such as mica. Thereby, when manufacturing a washing machine, since the restriction | limiting with respect to the order of work, such as an assembly, is lose | eliminated, design becomes easy.
また、本実施の形態では、操作ボタン7と操作パネル8とが一体的に成形された構成を例に説明したが、これに限られない。例えば、操作ボタンのみを透明材料などで形成して別々の部品で構成してもよい。これにより、操作ボタン7を光らせてわかりやすく表示することができるとともに、一体的に形成する必要がなくなるため、設計が容易になる。
In this embodiment, the configuration in which the operation button 7 and the operation panel 8 are integrally formed has been described as an example, but the present invention is not limited to this. For example, only the operation buttons may be formed of a transparent material or the like and may be configured by separate parts. Thus, the operation button 7 can be illuminated and displayed in an easy-to-understand manner, and it is not necessary to form it integrally, so that the design is facilitated.

FIG. 8 is a cross-sectional view of a main part around the power supply device and the operation device of the washing machine according to the second embodiment of the present invention.
つまり、本実施の形態の洗濯機は、操作装置の一部を構成する電源装置の第1の不燃カバーをインサート成形して形成する舟状保護ケースに代えて、舟状保護ケースと電源基板との間に不燃材を設けた点で、実施の形態1と異なる。なお、実施の形態1の電源装置や操作装置およびそれらを備えた洗濯機と同じ構成要素や作用などの説明は、省略する。そこで、以下では、本実施の形態の特徴である電源装置80および操作装置70について、詳細に説明する。
That is, the washing machine of the present embodiment replaces the boat-like protective case formed by insert molding the first incombustible cover of the power supply device that constitutes a part of the operation device, It differs from Embodiment 1 by the point which provided the nonflammable material between. In addition, description of the same component, an effect | action, etc. as the power supply device of Embodiment 1, an operation device, and a washing machine provided with them is abbreviate | omitted. Therefore, in the following, the power supply device 80 and the operation device 70 which are features of the present embodiment will be described in detail.
なお、操作装置70を構成する操作基板9と電源基板11とを収容し保護する舟状保護ケース13(以下、「保護ケース13」と略記する)は、実施の形態1と同様に、例えば断面形状が略H形(H形を含む)で少なくとも表裏面に設けられた2つの凹部13a、13bを有する同じ部品からなる。このとき、電源基板11は、保護ケース13の一方の凹部13bに内包されて保護され、操作基板9は他方の凹部13aに内包されて保護されている。
A boat-like protective case 13 (hereinafter abbreviated as “protective case 13”) that accommodates and protects the operation board 9 and the power supply board 11 constituting the operation device 70 is, for example, a cross-section as in the first embodiment. The shape is substantially H-shaped (including H-shaped) and is composed of the same parts having at least two concave portions 13a and 13b provided on the front and back surfaces. At this time, the power supply substrate 11 is enclosed and protected in one recess 13b of the protective case 13, and the operation substrate 9 is enclosed and protected in the other recess 13a.
すなわち、図8に示すように、本実施の形態の洗濯機の電源装置80は、少なくとも電源基板11と、電源基板11を保護する保護ケース13と、例えばマイカ材41からなる不燃材41と、少なくとも電源基板11と不燃材41とを被覆するポッティング剤24と、から構成されている。
That is, as shown in FIG. 8, the power supply device 80 of the washing machine according to the present embodiment includes at least the power supply substrate 11, the protective case 13 that protects the power supply substrate 11, and the noncombustible material 41 made of, for example, mica material 41. The potting agent 24 covers at least the power supply substrate 11 and the non-combustible material 41.
また、本実施の形態の洗濯機の操作装置70は、筐体の上部外郭3に設けられる操作パネル8と、操作を入力する操作基板9と、電源装置80を構成する電源基板11と、電源基板11および操作基板9を保護する保護ケース13と、から構成されている。
The operation device 70 of the washing machine of the present embodiment includes an operation panel 8 provided on the upper outer shell 3 of the casing, an operation board 9 for inputting an operation, a power supply board 11 constituting a power supply device 80, a power supply The protective case 13 protects the substrate 11 and the operation substrate 9.
そして、不燃材41であるマイカ材41は、保護ケース13のうち、電源基板11が収容されている一方の凹部13bの底部13eと電源基板11との間に配置され、保護ケース13の底部13eに装着されている。
The mica material 41 that is the non-combustible material 41 is disposed between the bottom portion 13e of the recess 13b in which the power supply substrate 11 is accommodated in the protective case 13 and the power supply substrate 11, and the bottom portion 13e of the protective case 13 It is attached to.
このとき、不燃材41であるマイカ材41は、例えば500℃以上の高温状態でも優れた絶縁性能を備えている。そのため、搭載される、例えば洗濯機などの製品の高出力化などにより、電源基板11に実装した部品の温度が上昇した場合でも、絶縁性能を確保できる。さらに、電源基板11に実装したマイクロコンピュータ20やコネクタ22などの部品のリード部(図示せず)が、例えマイカ材41に接触しても、リード部間の絶縁抵抗は低下しない。その結果、洗濯機などの製品の誤表示や誤動作を防止できる。また、電源基板11の商用電源に接続した高圧回路が故障して発熱した場合でも、高い耐熱性を有するマイカ材41により、絶縁性能を確保できる。その結果、例え故障時においても、高い安全性を維持し、高い信頼性を確保できる。
At this time, the mica material 41 which is the non-combustible material 41 has an excellent insulating performance even in a high temperature state of, for example, 500 ° C. or more. Therefore, insulation performance can be ensured even when the temperature of components mounted on the power supply board 11 rises due to higher output of a product such as a washing machine to be mounted. Furthermore, even if lead parts (not shown) of components such as the microcomputer 20 and the connector 22 mounted on the power supply substrate 11 contact the mica material 41, the insulation resistance between the lead parts does not decrease. As a result, erroneous display and malfunction of products such as washing machines can be prevented. Further, even when the high voltage circuit connected to the commercial power supply of the power supply substrate 11 breaks down and generates heat, the mica material 41 having high heat resistance can ensure insulation performance. As a result, it is possible to maintain high safety and ensure high reliability even in the event of a failure.
さらに、操作装置70を構成する操作基板9および電源基板11に装着した、例えば操作スイッチ10のリード部10aやコネクタ22など部品のリード部(図示せず)が、操作基板9や電源基板11の裏面から突出した場合でも、保護ケース13の樹脂層あるいはマイカ材41と接触する。そのため、部品のリード部間の抵抗の低下を防止できる。その結果、信頼性に優れた電源装置80を有する操作装置70および誤動作や誤表示を防止できる洗濯機を実現できる。
Furthermore, lead parts (not shown) of components such as the lead part 10 a of the operation switch 10 and the connector 22 mounted on the operation board 9 and the power supply board 11 constituting the operation device 70 are connected to the operation board 9 and the power supply board 11. Even when protruding from the back surface, it contacts the resin layer of the protective case 13 or the mica material 41. Therefore, it is possible to prevent a decrease in resistance between the lead portions of the component. As a result, it is possible to realize the operating device 70 having the power supply device 80 with excellent reliability and the washing machine capable of preventing malfunction and display error.
以下に、本実施の形態のマイカ材を備える電源装置80の作製方法について、簡単に説明する。
Hereinafter, a method for manufacturing the power supply device 80 including the mica material of the present embodiment will be briefly described.
まず、例えば断面形状が略H形(H形を含む)の保護ケース13の凹部13b側の底部13eを上向きにして水平に設置する。
First, for example, the protective case 13 having a substantially H-shaped cross section (including the H shape) is horizontally installed with the bottom 13e on the recess 13b side facing upward.
つぎに、不燃材41であるマイカ材41を、保護ケース13の底部13eに配置する。
Next, the mica material 41 that is the non-combustible material 41 is disposed on the bottom 13 e of the protective case 13.
そして、上記状態で、電源基板11を保護ケース13の電源基板固定爪16に固定する。
In the above state, the power supply board 11 is fixed to the power supply board fixing claw 16 of the protective case 13.
その後、例えばウレタン樹脂などのポッティング剤24を流し込んだ状態で、高温槽に入れ、例えば60℃で、ポッティング剤24を乾燥し、硬化させる。
Thereafter, the potting agent 24 such as urethane resin is poured into a high-temperature bath, and the potting agent 24 is dried and cured at 60 ° C., for example.
そして、保護ケース13の凹部13bの底部13eにマイカ材41が装着され、電源基板11とともに、ポッティング剤24で被覆されて電源装置80が作製される。
The mica material 41 is attached to the bottom 13e of the recess 13b of the protective case 13, and the power supply substrate 80 is covered with the potting agent 24 together with the power supply substrate 11 to produce the power supply device 80.
これにより、一般に、薄くて脆いマイカ材41を不燃材41として用いても、ポッティング後は、ポッティング剤24でマイカ材41が保護ケース13に固定される。そのため、マイカ材41の変形や剥離による品質の劣化を防いで、絶縁性能を長期間確保できる。
Thereby, generally, even if the thin and brittle mica material 41 is used as the noncombustible material 41, the mica material 41 is fixed to the protective case 13 by the potting agent 24 after potting. Therefore, deterioration of quality due to deformation and peeling of the mica material 41 can be prevented, and insulation performance can be ensured for a long time.
また、一般に、マイカ材41は空気中の水分を吸収すると、絶縁性能が劣化しやすい。しかし、ポッティング剤24で固定することにより、マイカ材41を空気から遮断できる。その結果、水分吸収によるマイカ材41の品質の劣化を防いで、安全で信頼性の高い電源装置80と操作装置70およびそれを備えた洗濯機を実現できる。
In general, when the mica material 41 absorbs moisture in the air, the insulating performance tends to deteriorate. However, the mica material 41 can be shielded from the air by fixing with the potting agent 24. As a result, the quality of the mica material 41 is prevented from deteriorating due to moisture absorption, and a safe and highly reliable power supply device 80 and operation device 70 and a washing machine equipped with the same can be realized.
また、保護ケース13の一方の凹部13bに、電源装置80を構成する電源基板11を収容して保護し、裏面側の凹部13aに操作基板9を収容して保護することにより、電源装置80を備えた操作装置70を作製できる。その結果、操作装置70をコンパクトに構成できるとともに、洗濯機などの製品の全体を小型化できる。
Further, the power supply substrate 11 constituting the power supply device 80 is accommodated and protected in one concave portion 13b of the protective case 13, and the operation substrate 9 is accommodated and protected in the concave portion 13a on the back surface side, whereby the power supply device 80 is protected. The provided operating device 70 can be produced. As a result, the operating device 70 can be configured compactly, and the entire product such as a washing machine can be downsized.
以下に、本実施の形態の電源装置および操作装置の別の構成について、図8を参照しながら説明する。
Hereinafter, another configuration of the power supply device and the operation device according to the present embodiment will be described with reference to FIG.
つまり、図8に示すように、本実施の形態の別の例の電源装置80および操作装置70は、電源基板11のマイカ材41が設けられる位置と対向する一部の箇所に確認窓42(通孔)を設ける点で、上記の電源装置80および操作装置70と異なる。同様に、通常、マイカ材41の一部は、電源基板11の外周の端部よりもはみ出すように設けられるので、はみ出して設けられた範囲のマイカ材41を、電源基板11の少なくとも一端から観察する確認用隙間43(通孔)を設ける点でも、上記の電源装置80および操作装置70とは異なる。他の構成は同様であるので、説明を省略する。
That is, as shown in FIG. 8, the power supply device 80 and the operation device 70 of another example of the present embodiment have a confirmation window 42 (on the part of the power supply substrate 11 facing the position where the mica material 41 is provided. It differs from the power supply device 80 and the operation device 70 in that a through hole is provided. Similarly, since a part of the mica material 41 is usually provided so as to protrude beyond the outer peripheral end of the power supply substrate 11, the mica material 41 in the protruding range is observed from at least one end of the power supply substrate 11. The difference from the power supply device 80 and the operation device 70 also in that a confirmation gap 43 (through hole) is provided. Since other configurations are the same, description thereof is omitted.
このとき、図8に示すように、確認窓42の、例えば直径d1は、電源基板11とマイカ材41との隙間g3より大きく形成する。これにより、電源装置80や操作装置70を製造する際、製造現場の照明光を、確認窓42を通してマイカ材41の表面まで到達させることができる。その結果、マイカ材41の装着の有無を確実に、確認窓42を介して、目視で確認できる。
At this time, as shown in FIG. 8, for example, the diameter d1 of the confirmation window 42 is formed larger than the gap g3 between the power supply substrate 11 and the mica material 41. Thereby, when manufacturing the power supply device 80 and the operation device 70, the illumination light of a manufacturing site can be made to reach the surface of the mica material 41 through the confirmation window 42. As a result, the presence or absence of the mica material 41 can be reliably confirmed visually through the confirmation window 42.
また、マイカ材41は略白色(白色を含む)で、保護ケース13は略黒色(黒色を含む)で、ポッティング剤24は略透明(透明を含む)な材料で構成される。なお、少なくともマイカ材41の色と、保護ケース13の色とを、異なる色で構成すれば、マイカ材41の色と保護ケース13の色との組み合わせは任意である。
The mica material 41 is substantially white (including white), the protective case 13 is substantially black (including black), and the potting agent 24 is substantially transparent (including transparent). In addition, as long as at least the color of the mica material 41 and the color of the protective case 13 are configured in different colors, the combination of the color of the mica material 41 and the color of the protective case 13 is arbitrary.
これにより、マイカ材41の一部は、確認用隙間43や確認窓42から目視で確認できる。その結果、保護ケース13の底部13eに装着されるマイカ材41の、例えば製造時における装着忘れを防止できる。
Thereby, a part of the mica material 41 can be visually confirmed through the confirmation gap 43 and the confirmation window 42. As a result, forgetting to attach the mica material 41 attached to the bottom 13e of the protective case 13 at the time of manufacture, for example, can be prevented.
すなわち、電源基板11に設けた確認窓42や確認用隙間43により、ポッティング剤24を通して、マイカ材41の装着の有無を観察できる。そのため、電源装置80および操作装置70の製造の際、マイカ材41を目視で確認したときに、保護ケース13の略黒色ではなく、マイカ材41の略白色があることを確認して、マイカ材41の装着忘れを防止できる。
That is, whether or not the mica material 41 is attached can be observed through the potting agent 24 through the confirmation window 42 and the confirmation gap 43 provided on the power supply substrate 11. Therefore, when manufacturing the power supply device 80 and the operation device 70, when the mica material 41 is visually confirmed, it is confirmed that the protective case 13 is not substantially black but the mica material 41 is substantially white. Forgetting to wear 41 can be prevented.

This makes it difficult for water to collect in the accommodating portion, and the operation board can be waterproofed more reliably. Further, it is possible to prevent foam generated in the inner tub during washing from entering the area of the operation substrate. As a result, it is possible to realize a highly reliable washing machine that prevents erroneous display and malfunction.
また、本発明の洗濯機は、操作パネルを、さらに備え、防水部は、保護ケースに設けられた溝と操作パネルに設けられたリブとが対応することにより構成されるラビリンス構造を有し、溝は、操作基板を囲む全周に渡って設けられている。
