本発明によれば、乾燥運転中の熱により洗濯に用いる液剤の加熱を抑制することができる。
According to the present invention, it is possible to suppress the heating of the liquid agent used for washing by the heat during the drying operation.
以下、図面を参照して、本発明の実施の形態(以下、「本実施形態」と称する)について詳細に説明する。なお、各図は、本発明を十分に理解できる程度に、概略的に示しているに過ぎない。よって、本発明は、図示例のみに限定されるものではない。また、各図において、共通する構成要素や同様な構成要素については、同一の符号を付し、それらの重複する説明を省略する。
Hereinafter, embodiments of the present invention (hereinafter referred to as “the present embodiments”) will be described in detail with reference to the drawings. It should be noted that each figure is merely schematically shown to the extent that the present invention can be fully understood. Therefore, the present invention is not limited to the illustrated examples. Further, in each figure, common components and similar components are designated by the same reference numerals, and duplicate description thereof will be omitted.
なお、本実施形態は、従来の洗濯乾燥機における以下の課題を解決することができる洗濯乾燥機を提供することも技術的思想にしている。例えば、従来の洗濯乾燥機において、特に縦型式の洗濯乾燥機では、乾燥運転時に比較的高温になり易い部位の上方に、タンクや自動投入部(特許文献1の洗濯処理液自動投入手段に相当)が配置されている。比較的高温になり易い部位とは、例えば、乾燥運転時に筐体の内部で循環される循環風を加熱する熱源となるヒータ(加熱部)や、ヒータで加熱された温風が通過する水槽等である。比較的高温になり易い部位からタンクや自動投入部までの距離が近いと、乾燥運転中の熱により、洗剤や柔軟剤等の洗濯に用いる液剤(洗濯処理液)が加熱される。液剤(洗濯処理液)が加熱されると、液剤(洗濯処理液)の特性が変化して、例えば、洗剤の洗浄能力が低下する現象が発生したり、柔軟剤が固まってしまって自動投入手段(特許文献1の洗濯処理液自動投入手段に相当)から水槽内に柔軟剤を良好に投入できなくなる現象が発生したりする可能性がある。そこで、縦型式の洗濯乾燥機では、比較的高温になり易い部位からタンクや自動投入部までの距離を一定以上に確保するために、比較的高温になり易い部位の上方からずらした位置にタンクや自動投入部を配置することが検討されている。この構成によれば、比較的高温になり易い部位からタンクや自動投入部までの距離が一定以上に確保されているため、液剤(洗濯処理液)が加熱されることを抑制することができる。しかしながら、この構成の縦型式の洗濯乾燥機は、タンクや自動投入部をずらした位置の分だけ、筐体サイズ(特に左右方向又は前後方向のサイズ)が増大するため、筐体サイズの小型化が阻害されてしまう、という課題が発生する。そこで、本実施形態は、このような課題を解決することができる洗濯乾燥機を提供することも技術的思想にしている。
It should be noted that the present embodiment also has a technical idea of providing a washer / dryer that can solve the following problems in the conventional washer / dryer. For example, in a conventional washer / dryer, especially in a vertical type washer / dryer, a tank or an automatic charging unit (corresponding to the washing treatment liquid automatic charging means of Patent Document 1) is located above a portion where a relatively high temperature is likely to occur during a drying operation. ) Is placed. The parts that tend to be relatively hot are, for example, a heater (heating part) that is a heat source for heating the circulating air circulated inside the housing during the drying operation, a water tank through which the warm air heated by the heater passes, and the like. Is. When the distance from the part where the temperature tends to be relatively high to the tank or the automatic charging part is short, the liquid (washing treatment liquid) used for washing such as detergent and softener is heated by the heat during the drying operation. When the liquid agent (washing treatment liquid) is heated, the characteristics of the liquid agent (washing treatment liquid) change, for example, a phenomenon that the cleaning ability of the detergent is lowered or the softener is solidified and the automatic charging means (Corresponding to the automatic washing liquid charging means of Patent Document 1), there is a possibility that a phenomenon may occur in which the softener cannot be satisfactorily charged into the water tank. Therefore, in the vertical type washer-dryer, in order to secure the distance from the part that tends to be relatively hot to the tank or the automatic loading part to a certain level or more, the tank is positioned at a position shifted from above the part that tends to be relatively hot. And the placement of an automatic loading unit is being considered. According to this configuration, since the distance from the portion where the temperature tends to be relatively high to the tank or the automatic charging portion is secured to a certain level or more, it is possible to suppress the liquid agent (washing treatment liquid) from being heated. However, in the vertical washer-dryer with this configuration, the housing size (especially the size in the left-right direction or the front-back direction) increases by the amount of the position where the tank and the automatic loading part are shifted, so the housing size is reduced. Is hindered. Therefore, the present embodiment also has a technical idea of providing a washer / dryer capable of solving such a problem.

Further, the water cooling unit 14 may be configured to abut on the detergent tank 91 to directly cool the liquid agent (washing treatment liquid) inside the detergent tank 91 or the detergent tank 91.
図2に示すように、筐体1の内部の背面付近には、乾燥ダクト接続部27により外槽3と接続された乾燥ダクト11が配置されている。乾燥ダクト11の上部には、送風を行うために送風ユニット20が配置されている。また、送風ユニット20と洗濯兼脱水槽4との間には、温風送風路25が配置されている。外槽3と乾燥ダクト接続部27と乾燥ダクト11と送風ユニット20と温風送風路25とは、乾燥運転中に空気が循環する経路を構成する。
As shown in FIG. 2, a drying duct 11 connected to the outer tank 3 by a drying duct connecting portion 27 is arranged near the back surface inside the housing 1. A ventilation unit 20 is arranged on the upper part of the drying duct 11 to blow air. Further, a warm air air passage 25 is arranged between the air blower unit 20 and the washing / dehydrating tank 4. The outer tank 3, the drying duct connecting portion 27, the drying duct 11, the air blowing unit 20, and the warm air air passage 25 form a path for air to circulate during the drying operation.
送風ユニット20は、送風ファン12、循環風温度センサ21と、温風温度センサ22と、ヒータ24(加熱部)とを有している。循環風温度センサ21は、ヒータ24(加熱部)によって加熱された後に筐体1の内部で循環してヒータ24の手前の位置に戻された空気(循環風)の温度を検知するセンサである。温風温度センサ22は、ヒータ24(加熱部)によって加熱された空気(温風)の温度を検知するセンサである。
The blower unit 20 has a blower fan 12, a circulating air temperature sensor 21, a warm air temperature sensor 22, and a heater 24 (heating unit). The circulating air temperature sensor 21 is a sensor that detects the temperature of the air (circulating air) that has been heated by the heater 24 (heating unit) and then circulated inside the housing 1 and returned to the position in front of the heater 24. .. The hot air temperature sensor 22 is a sensor that detects the temperature of the air (warm air) heated by the heater 24 (heating unit).
後記する乾燥運転工程(図5のステップS37)時において、洗濯乾燥機100の内部では、送風ユニット20により作られた風が、ヒータ24を通過することで温風となり、温風送風路25を介して洗濯兼脱水槽4の内部の洗濯物へ送られる。温風により洗濯物が温められることで、洗濯物から蒸発した水分が発生する。温風は、蒸発した水分を含んだ状態で下流側に流れ、乾燥ダクト接続部27を通過して、乾燥ダクト11へ流れ込む。さらに温風は、送風ユニット接続部28を通過して循環風として送風ユニット20に戻る。循環風は、送風ユニット20を経てヒータ24に戻り、温風として前回と同じ経路を循環する。
At the time of the drying operation step (step S37 in FIG. 5) described later, inside the washer / dryer 100, the air produced by the blower unit 20 becomes warm air by passing through the heater 24, and the warm air blower passage 25 is provided. It is sent to the laundry inside the washing / dehydrating tub 4 via the washing / dehydrating tub 4. When the laundry is warmed by the warm air, the moisture evaporated from the laundry is generated. The warm air flows downstream in a state containing evaporated water, passes through the drying duct connecting portion 27, and flows into the drying duct 11. Further, the warm air passes through the blower unit connection portion 28 and returns to the blower unit 20 as circulating air. The circulating air returns to the heater 24 via the blower unit 20 and circulates as warm air in the same path as the previous time.
また、後記する乾燥運転工程(図5のステップS37)時において、洗濯乾燥機100の内部では、水道の家庭用の水栓から取り込まれた水道水が温風の除湿を行うための冷却水として使用される。このとき、冷却水は、給水ユニット8に一時的に溜められる。そして、冷却水は、給水ユニット8から水冷部接続管13を経て水冷部14の内部に流れる。水冷部14の内部には、冷却水を流すための流路14b(図3B、並びに、図4A乃至図4C参照)が形成されている。流路14bの内部で冷却水が所定の水位を超えると(例えば、流路14bの内部が冷却水で満たされると)、冷却水が水冷部14から冷却水管15に流れ出て、乾燥ダクト11に流れ込む。乾燥ダクト11の内部では、流れ落ちる冷却水により水分を多量に含む温風が冷却されて、温風中の水分が凝縮されることで、結露水が発生して、温風が除湿される。凝縮回収された結露水は、冷却水と混合して、乾燥ダクト11を流れ落ち、乾燥ダクト接続部27、排水弁18、排水ホース19を通過して洗濯乾燥機100の外部へ排出される。乾燥ダクト11を上昇することで除湿された温風は、ヒータ24へと向かう。
Further, in the drying operation step (step S37 in FIG. 5) described later, inside the washing / drying machine 100, tap water taken in from a household faucet of tap water is used as cooling water for dehumidifying hot air. used. At this time, the cooling water is temporarily stored in the water supply unit 8. Then, the cooling water flows from the water supply unit 8 to the inside of the water cooling unit 14 via the water cooling unit connecting pipe 13. Inside the water cooling unit 14, a flow path 14b (see FIGS. 3B and 4A to 4C) for flowing cooling water is formed. When the cooling water exceeds a predetermined water level inside the flow path 14b (for example, when the inside of the flow path 14b is filled with the cooling water), the cooling water flows out from the water cooling portion 14 to the cooling water pipe 15 and enters the drying duct 11. It flows in. Inside the drying duct 11, the warm air containing a large amount of water is cooled by the cooling water that flows down, and the water in the warm air is condensed to generate dew condensation water and dehumidify the warm air. The condensed and recovered dew condensation water mixes with the cooling water, flows down the drying duct 11, passes through the drying duct connection portion 27, the drain valve 18, and the drain hose 19, and is discharged to the outside of the washing / drying machine 100. The warm air dehumidified by ascending the drying duct 11 goes to the heater 24.
洗濯乾燥機100は、後記する乾燥運転工程(図5のステップS37)時に、前記した温風(ヒータ24によって加熱された空気)の温度を温風温度センサ22で検知するとともに、前記した循環風(ヒータ24によって加熱された後に筐体1の内部で循環してヒータ24の手前の位置に戻された空気)の温度を循環風温度センサ21で検知して、温風の温度及び循環風の温度を監視しながら、乾燥運転を行う。
The washing / drying machine 100 detects the temperature of the hot air (air heated by the heater 24) described above by the warm air temperature sensor 22 during the drying operation step (step S37 in FIG. 5) described later, and the circulating air described above. The temperature of (air that has been heated by the heater 24 and then circulated inside the housing 1 and returned to the position in front of the heater 24) is detected by the circulating air temperature sensor 21, and the temperature of the warm air and the circulating air Perform drying operation while monitoring the temperature.

Further, the washer / dryer 100 drains the temperature of the warm air after passing through the laundry in the water-cooled dehumidifying / supplying water step (step S37b in FIG. 5) described later in the drying operation step (step S37 in FIG. 5) described later. The drying operation is performed while detecting with the temperature sensor 23 and monitoring the temperature of the warm air after passing through the laundry.

3A to 4C show a specific configuration of the
図3A及び図3Bに示すように、本実施形態では、水冷部14は、洗剤自動投入ユニット9の下部に装着される構成になっている。
As shown in FIGS. 3A and 3B, in the present embodiment, the water cooling unit 14 is configured to be mounted on the lower part of the detergent automatic charging unit 9.
図3B、並びに、図4A乃至図4Cに示すように、水冷部14は、給水ユニット8から供給される冷却水を内部に導入する導入口14aと、冷却水を流す流路14bと、冷却水を外部に排出する排出口14cと、を備えている。また、水冷部14は、洗剤自動投入ユニット9の洗剤投入配管92が載置され、洗剤投入配管92を冷却する投入配管冷却部14dを備えている。
As shown in FIGS. 3B and 4A to 4C, the water cooling unit 14 includes an introduction port 14a for introducing the cooling water supplied from the water supply unit 8 into the inside, a flow path 14b for flowing the cooling water, and cooling water. It is provided with a discharge port 14c for discharging the water to the outside. Further, the water cooling unit 14 is provided with a charging pipe cooling unit 14d on which the detergent charging pipe 92 of the detergent automatic charging unit 9 is placed and which cools the detergent charging pipe 92.
水冷部14は、給水ユニット8から供給される冷却水を導入口14aから内部に導入する。冷却水は、流路14bの内部を流れる。流路14bは、上下方向に複数の層構造になっている。ここでは、流路14bが上側層と下側層の2層構造になっているものとして説明する。流路14bの上側層には、下側層に通じる開口部が設けられている。水冷部14の内部に導入された冷却水は、まず流路14bの上側層に溜められる。そして流路14bの内部で冷却水が所定の水位を超えると(例えば、流路14bの内部が冷却水で満たされると)、開口部を通して冷却水が下側層に落下する。下側層に落下した冷却水は、排出口14cを通って水冷部14から冷却水管15に流れ出る。冷却水管15(図2参照)に流れ出た冷却水は、乾燥ダクト11(図2参照)に流れ込む。水冷部14は、乾燥運転の水冷除湿給水で使用される冷却水を流路14bに流すことで、液剤(洗濯処理液)を冷却する。
The water cooling unit 14 introduces the cooling water supplied from the water supply unit 8 into the inside from the introduction port 14a. The cooling water flows inside the flow path 14b. The flow path 14b has a plurality of layered structures in the vertical direction. Here, it is assumed that the flow path 14b has a two-layer structure of an upper layer and a lower layer. The upper layer of the flow path 14b is provided with an opening leading to the lower layer. The cooling water introduced into the water cooling unit 14 is first stored in the upper layer of the flow path 14b. When the cooling water exceeds a predetermined water level inside the flow path 14b (for example, when the inside of the flow path 14b is filled with the cooling water), the cooling water falls to the lower layer through the opening. The cooling water that has fallen to the lower layer flows out from the water cooling unit 14 to the cooling water pipe 15 through the discharge port 14c. The cooling water that has flowed out into the cooling water pipe 15 (see FIG. 2) flows into the drying duct 11 (see FIG. 2). The water cooling unit 14 cools the liquid agent (washing treatment liquid) by flowing the cooling water used in the water cooling / dehumidifying / supplying water in the drying operation to the flow path 14b.
水冷部14は、乾燥運転中に常に冷却水が流れ続けることで、冷却水温と同程度の温度に冷却されている。そのため、洗濯乾燥機100は、洗剤タンク91や洗剤投入配管92、洗剤自動投入ユニット9の内部の液剤(洗濯処理液)に乾燥運転中の熱の影響を与えることなく、液剤(洗濯処理液)を冷却することができる。したがって、洗濯乾燥機100は、洗剤タンク91や洗剤自動投入ユニット9の内部に溜められている液剤(洗濯処理液)の加熱を抑制することができる。
The water cooling unit 14 is cooled to a temperature similar to the cooling water temperature by constantly flowing cooling water during the drying operation. Therefore, the washing / drying machine 100 does not affect the liquid (washing liquid) inside the detergent tank 91, the detergent charging pipe 92, and the detergent automatic charging unit 9 with heat during the drying operation, and the liquid (washing liquid). Can be cooled. Therefore, the washer / dryer 100 can suppress the heating of the liquid agent (washing treatment liquid) stored inside the detergent tank 91 and the detergent automatic charging unit 9.
水冷部14は、洗剤自動投入ユニット9や洗剤自動投入ユニット9と接触している、あるいは近接して配置されることが望ましい。本実施形態では、水冷部14は、洗剤自動投入ユニット9の下部に装着され、洗剤自動投入ユニット9の洗剤投入配管92と接触するように配置されている。ただし、水冷部14は、洗剤タンク91の下部や内部に配置することで、洗剤タンク91の内部の液剤(洗濯処理液)を直接冷却することもできる。
It is desirable that the water cooling unit 14 is in contact with or in close contact with the detergent automatic charging unit 9 and the detergent automatic charging unit 9. In the present embodiment, the water cooling unit 14 is mounted on the lower part of the detergent automatic charging unit 9 and is arranged so as to be in contact with the detergent charging pipe 92 of the detergent automatic charging unit 9. However, by arranging the water cooling unit 14 at the bottom or inside of the detergent tank 91, the liquid agent (washing treatment liquid) inside the detergent tank 91 can be directly cooled.

Hereinafter, the operation of the washer /
例えば、使用者が洗濯物を洗濯兼脱水槽4に投入して操作入力部2から洗濯乾燥運転の開始を洗濯乾燥機100に指示したとする。すると、図5に示すように、洗濯乾燥機100は、以下のステップS21からステップS38までの動作を行う。
For example, suppose that the user puts the laundry into the washing / dehydrating tub 4 and instructs the washing / drying machine 100 to start the washing / drying operation from the operation input unit 2. Then, as shown in FIG. 5, the washer / dryer 100 performs the following operations from step S21 to step S38.
まず、洗濯乾燥機100は、モータ6により攪拌翼7を所定の回転パターンで駆動させ、モータ6に流れる電流値により洗濯物の量(布量)を判定(確認)する(ステップS21)。このとき、洗濯乾燥機100は、運転終了までの目安時間を表示部34に表示する。そして、洗濯乾燥機100は、洗濯物の量の判定結果(確認結果)に応じた量の洗剤(洗剤液)を洗剤自動投入ユニット9(自動投入部)により洗濯兼脱水槽4に投入する(ステップS22)。
First, the washer / dryer 100 drives the stirring blade 7 with a predetermined rotation pattern by the motor 6, and determines (confirms) the amount of laundry (cloth amount) based on the current value flowing through the motor 6 (step S21). At this time, the washer / dryer 100 displays the estimated time until the end of the operation on the display unit 34. Then, the washing / drying machine 100 charges the amount of detergent (detergent liquid) according to the determination result (confirmation result) of the amount of laundry into the washing / dehydrating tub 4 by the detergent automatic charging unit 9 (automatic charging unit) (the washing / dehydrating tank 4). Step S22).
次に、洗濯乾燥機100は、給水ユニット8を介して外部(水道の家庭用水栓)から水道水を内部に取り込み、取り込まれた水道水を洗濯兼脱水槽4の内部に供給(給水)する(ステップS23)。洗濯物の量の判定結果(確認結果)に応じた量の水道水が洗濯兼脱水槽4の内部に溜まると、洗濯乾燥機100は、モータ6により攪拌翼7を回転駆動させて、洗剤を用いた洗濯物の洗い処理を行う(ステップS24)。洗い処理が終わると、洗濯乾燥機100は、洗濯兼脱水槽4の内部の水を外部に排出(排水)し(ステップS25)、モータ6により洗濯兼脱水槽4を回転駆動させて、脱水処理を行う(ステップS26)。
Next, the washing / drying machine 100 takes in tap water from the outside (household faucet of tap water) via the water supply unit 8 and supplies (watering) the taken-in tap water to the inside of the washing / dehydrating tank 4. (Step S23). When the amount of tap water corresponding to the determination result (confirmation result) of the amount of laundry is accumulated inside the washing / dehydrating tank 4, the washer / dryer 100 rotates the stirring blade 7 by the motor 6 to drive the detergent. The used laundry is washed (step S24). When the washing process is completed, the washer / dryer 100 discharges (drains) the water inside the washing / dehydrating tub 4 to the outside (step S25), and the washing / dehydrating tub 4 is rotationally driven by the motor 6 to perform the dehydration process. (Step S26).
次に、洗濯乾燥機100は、給水ユニット8を介して外部(水道の家庭用水栓)から水道水を内部に取り込み、取り込まれた水道水を洗濯兼脱水槽4の内部に供給(給水)する(ステップS27)。洗濯物の量の判定結果(確認結果)に応じた量の水道水が洗濯兼脱水槽4の内部に溜まると、洗濯乾燥機100は、1回目のすすぎ処理を行う(ステップS28)。1回目のすすぎ処理では、モータ6により攪拌翼7を回転駆動させて洗濯物を攪拌することで、洗剤で洗濯物を洗いつつ、洗濯物に染み込んだ洗剤を洗濯兼脱水槽4に供給された水に放出させる処理が行われる。1回目のすすぎ処理が終わると、洗濯乾燥機100は、洗濯兼脱水槽4の内部の水を外部に排出(排水)し(ステップS29)、モータ6により洗濯兼脱水槽4を回転駆動させて、脱水処理を行う(ステップS30)。
Next, the washing / drying machine 100 takes in tap water from the outside (household faucet of tap water) via the water supply unit 8 and supplies (watering) the taken-in tap water to the inside of the washing / dehydrating tank 4. (Step S27). When the amount of tap water corresponding to the determination result (confirmation result) of the amount of laundry is accumulated inside the washing / dehydrating tank 4, the washer / dryer 100 performs the first rinsing treatment (step S28). In the first rinsing process, the stirring blade 7 is rotationally driven by the motor 6 to stir the laundry, so that the laundry is washed with the detergent and the detergent soaked in the laundry is supplied to the washing / dehydrating tub 4. The process of releasing it into water is performed. After the first rinsing process is completed, the washer / dryer 100 discharges (drains) the water inside the washing / dehydrating tub 4 to the outside (step S29), and the washing / dehydrating tub 4 is rotationally driven by the motor 6. , Dehydration treatment is performed (step S30).
次に、洗濯乾燥機100は、給水ユニット8を介して外部(水道の家庭用水栓)から水道水を内部に取り込み、取り込まれた水道水を洗濯兼脱水槽4の内部に供給(給水)する(ステップS31)。洗濯物の量の判定結果(確認結果)に応じた量の水道水が洗濯兼脱水槽4の内部に溜まると、洗濯乾燥機100は、洗濯物の量の判定結果(確認結果)に応じた量の柔軟剤(柔軟剤液)を洗剤自動投入ユニット9(自動投入部)により洗濯兼脱水槽4に投入する(ステップS32)。
Next, the washing / drying machine 100 takes in tap water from the outside (household faucet of tap water) via the water supply unit 8 and supplies (watering) the taken-in tap water to the inside of the washing / dehydrating tank 4. (Step S31). When the amount of tap water corresponding to the determination result (confirmation result) of the amount of laundry is accumulated inside the washing / dehydrating tub 4, the washer / dryer 100 corresponds to the determination result (confirmation result) of the amount of laundry. An amount of the softener (softener liquid) is charged into the washing / dehydrating tank 4 by the detergent automatic charging unit 9 (automatic charging unit) (step S32).
次に、洗濯乾燥機100は、給水ユニット8を介して外部(水道の家庭用水栓)から水道水を内部に取り込み、取り込まれた水道水を洗濯兼脱水槽4の内部に供給(給水)する(ステップS33)。洗濯物の量の判定結果(確認結果)に応じた量の水道水が洗濯兼脱水槽4の内部に溜まると、洗濯乾燥機100は、2回目のすすぎ処理を行う(ステップS34)。2回目のすすぎ処理では、モータ6により攪拌翼7を回転駆動させて洗濯物を攪拌することで、洗濯物を柔軟剤に漬け込みつつ、洗濯物に染み込んだ柔軟剤を洗濯兼脱水槽4に供給された水に放出させる処理が行われる。2回目のすすぎ処理が終わると、洗濯乾燥機100は、洗濯兼脱水槽4の内部の水を外部に排出(排水)し(ステップS35)、モータ6により洗濯兼脱水槽4を回転駆動させて、最終的な脱水処理を行う(ステップS36)。
Next, the washing / drying machine 100 takes in tap water from the outside (household faucet of tap water) via the water supply unit 8 and supplies (watering) the taken-in tap water to the inside of the washing / dehydrating tank 4. (Step S33). When an amount of tap water corresponding to the determination result (confirmation result) of the amount of laundry is accumulated inside the washing / dehydrating tank 4, the washer / dryer 100 performs a second rinsing process (step S34). In the second rinsing process, the stirring blade 7 is rotationally driven by the motor 6 to stir the laundry, so that the laundry is immersed in the softener and the softener soaked in the laundry is supplied to the washing / dehydrating tank 4. A treatment is performed to release the water into the water. After the second rinsing process is completed, the washer / dryer 100 discharges (drains) the water inside the washing / dehydrating tub 4 to the outside (step S35), and the motor 6 rotates the washing / dehydrating tub 4 to drive the washing / dehydrating tub 4. , The final dehydration treatment is performed (step S36).
次に、洗濯乾燥機100は、洗濯物を乾燥させる乾燥運転を行う(ステップS37)。このステップS37の工程では、洗濯乾燥機100は、加熱送風工程(ステップS37a)、水冷除湿給水工程(ステップS37b)、及び乾燥確認工程(ステップS37c)を行う。
Next, the washer / dryer 100 performs a drying operation for drying the laundry (step S37). In the step S37, the washer / dryer 100 performs a heating / blowing step (step S37a), a water-cooled dehumidifying / dehumidifying / supplying step (step S37b), and a drying confirmation step (step S37c).
ステップS37aの加熱送風工程では、洗濯乾燥機100は、ヒータ24により空気を加熱しながら、送風ユニット20により筐体1の内部の空気を循環させることで、加熱された空気(温風)を作り、温風を洗濯兼脱水槽4の内部の洗濯物に通す。
In the heating and blowing step of step S37a, the washer / dryer 100 creates heated air (warm air) by circulating the air inside the housing 1 by the blowing unit 20 while heating the air by the heater 24. , Warm air is passed through the laundry inside the washing / dehydrating tub 4.
温風により洗濯物が温められることで、洗濯物から蒸発した水分が発生する。温風は、蒸発した水分を含んだ状態で下流側に流れ、乾燥ダクト接続部27を通過して、乾燥ダクト11へ流れ込む。さらに温風は、送風ユニット接続部28を通過して循環風として送風ユニット20に戻る。循環風は、送風ユニット20を経てヒータ24に戻り、温風として前回と同じ経路を循環する。
When the laundry is warmed by warm air, moisture evaporated from the laundry is generated. The warm air flows downstream in a state containing evaporated water, passes through the drying duct connecting portion 27, and flows into the drying duct 11. Further, the warm air passes through the blower unit connection portion 28 and returns to the blower unit 20 as circulating air. The circulating air returns to the heater 24 via the blower unit 20 and circulates as warm air in the same path as the previous time.
洗濯物の温度が低いと洗濯物から蒸発する水分は少ないため、洗濯乾燥機100は、ステップS37aの加熱送風工程を概ね15分程度実施する。加熱送風により洗濯物から水分の蒸発が始まったら、洗濯乾燥機100は、ステップS37bの水冷除湿給水工程を開始する。
When the temperature of the laundry is low, the amount of water that evaporates from the laundry is small, so the washer / dryer 100 carries out the heating and blowing step of step S37a for about 15 minutes. When the evaporation of water from the laundry is started by the heating air, the washer / dryer 100 starts the water-cooled dehumidifying / supplying step of step S37b.
ステップS37bの水冷除湿給水工程では、洗濯乾燥機100は、外部(水道の家庭用水栓)から給水口10介して水道水(冷却水)を給水ユニット8に取り込み、給水ユニット8から水冷部接続管13に通水する。そして、洗濯乾燥機100は、冷却水を水冷部14に供給(給水)する。水冷部14が水で満たされると、冷却水は、冷却水管15を経由して乾燥ダクト11に流れ込む。なお、ステップS37bの水冷除湿給水工程においても、洗濯乾燥機100は、加熱送風を継続する。すなわち、洗濯乾燥機100は、ヒータ24により空気を加熱しながら、送風ユニット20により筐体1の内部の空気を循環させることを継続する。
In the water-cooled dehumidifying / supplying water step of step S37b, the washing / drying machine 100 takes in tap water (cooling water) from the outside (water supply household faucet) into the water supply unit 8 through the water supply port 10, and the water cooling unit connecting pipe from the water supply unit 8. Water is passed through 13. Then, the washer / dryer 100 supplies (supplys) cooling water to the water cooling unit 14. When the water cooling portion 14 is filled with water, the cooling water flows into the drying duct 11 via the cooling water pipe 15. Even in the water-cooled dehumidifying / supplying water step of step S37b, the washer / dryer 100 continues to heat and blow air. That is, the washer / dryer 100 continues to circulate the air inside the housing 1 by the blower unit 20 while heating the air by the heater 24.
このようにして洗濯乾燥機100は、給水ユニット8を介して外部(水道の家庭用水栓)から水道水(冷却水)を内部に取り込み、水冷部14を介して、水道水(冷却水)を乾燥ダクト11に供給する。水冷部14の内部は、水が通る空間になっている。洗濯乾燥機100は、ステップS37bの水冷除湿給水工程やステップS38の送風冷却工程で使用する冷却水を這い回して、洗剤自動投入ユニット9の一部(本実施形態では、洗剤投入配管92)を冷却する。
In this way, the washing / drying machine 100 takes in tap water (cooling water) from the outside (water supply household faucet) through the water supply unit 8 and takes in tap water (cooling water) through the water cooling unit 14. It is supplied to the drying duct 11. The inside of the water cooling unit 14 is a space through which water can pass. The washing / drying machine 100 crawls the cooling water used in the water cooling / dehumidifying / supplying step of step S37b and the blast cooling step of step S38 to crawl a part of the detergent automatic charging unit 9 (detergent charging pipe 92 in this embodiment). Cooling.
乾燥ダクト11の内部では、冷却水により乾燥ダクト11の内部を通る温風が冷却されて、温風に含まれている水分が凝縮される。これにより結露水が発生し、温風が除湿される。凝縮された結露水は、冷却水と混合して、乾燥ダクト11を流れ落ち、乾燥ダクト接続部27、排水弁18、排水ホース19を通過して洗濯乾燥機100の外部へ排出される。
Inside the drying duct 11, the warm air passing through the inside of the drying duct 11 is cooled by the cooling water, and the moisture contained in the warm air is condensed. As a result, dew condensation water is generated and warm air is dehumidified. The condensed dew condensation water mixes with the cooling water, flows down the drying duct 11, passes through the drying duct connection portion 27, the drain valve 18, and the drain hose 19, and is discharged to the outside of the washing / drying machine 100.
洗濯乾燥機100は、乾燥運転中の空気の温度を温風温度センサ22と排水温度センサ23と循環風温度センサ21とで監視している。例えば、洗濯乾燥機100は、ヒータ24で加熱された直後の空気(温風)の温度を温風温度センサ22で監視する。また、洗濯乾燥機100は、洗濯物を通過した後の温風の温度を排水温度センサ23で監視する。また、洗濯乾燥機100は、洗濯物を通過した後に、冷却水で除湿冷却されて、再び送風ユニット20へ戻ってきたときの空気(循環風)の温度を循環風温度センサ21で監視する。
The washing / drying machine 100 monitors the temperature of the air during the drying operation with the warm air temperature sensor 22, the drainage temperature sensor 23, and the circulating air temperature sensor 21. For example, the washer / dryer 100 monitors the temperature of the air (warm air) immediately after being heated by the heater 24 with the warm air temperature sensor 22. Further, the washer / dryer 100 monitors the temperature of the warm air after passing through the laundry with the drainage temperature sensor 23. Further, the washer / dryer 100 monitors the temperature of the air (circulating air) when it is dehumidified and cooled by cooling water after passing through the laundry and returned to the blowing unit 20 again with the circulating air temperature sensor 21.
ステップS37cの乾燥確認工程では、洗濯乾燥機100は、洗濯物が乾燥したことを確認する。このとき、洗濯乾燥機100は、例えば、循環風温度センサ21の測定値と排水温度センサ23の測定値とが所定温度になったことを検知することで、洗濯物が乾燥したことを確認する。
In the drying confirmation step of step S37c, the washer / dryer 100 confirms that the laundry has dried. At this time, the washing / drying machine 100 confirms that the laundry has dried by detecting, for example, that the measured value of the circulating air temperature sensor 21 and the measured value of the drainage temperature sensor 23 have reached a predetermined temperature. ..
ステップS37cで、洗濯物の乾燥が確認されると、洗濯乾燥機100は、冷却風を洗濯兼脱水槽4の内部の洗濯物に送風する(ステップS38)。このとき、洗濯乾燥機100は、ヒータ24を停止し、乾燥ダクト11に供給される冷却水で筐体1の内部を循環する空気を冷却しながら、冷却した空気(冷却風)を洗濯兼脱水槽4の内部の洗濯物に通す。
When the laundry is confirmed to be dry in step S37c, the washer / dryer 100 blows cooling air to the laundry inside the washing / dehydrating tub 4 (step S38). At this time, the washing / drying machine 100 stops the heater 24 and cools the air circulating inside the housing 1 with the cooling water supplied to the drying duct 11, while washing and removing the cooled air (cooling air). Pass it through the laundry inside the water tank 4.
洗濯乾燥機100は、ステップS21からステップS38までの処理を行うと、運転を終了する。なお、洗濯運転の場合は、ステップS36の最終脱水工程を以って、運転終了となる。これらの一連の動作では、給水口10と接続されている水道の家庭用水栓は、洗濯乾燥機100に給水可能な状態となっている。
The washer / dryer 100 ends its operation when the processes from step S21 to step S38 are performed. In the case of the washing operation, the operation is completed by the final dehydration step of step S36. In these series of operations, the household faucet of the water supply connected to the water supply port 10 is in a state where water can be supplied to the washer / dryer 100.
前記した洗濯乾燥機100の係る動作において、ステップS26,S29の脱水工程中に洗濯兼脱水槽4を収納する外槽3の振動が大きくなった場合は、加速度センサ30により振動が検出される。すると、洗濯乾燥機100は、洗濯兼脱水槽4を回転させているモータ6の脱水回転数を下げる、又は、ブレーキによりモータ6を停止する等の処置を行う。
In the above-mentioned operation of the washer / dryer 100, if the vibration of the outer tub 3 accommodating the washing / dehydrating tub 4 becomes large during the dehydration step of steps S26 and S29, the vibration is detected by the acceleration sensor 30. Then, the washer / dryer 100 takes measures such as lowering the dehydration rotation speed of the motor 6 rotating the washing / dehydrating tub 4 or stopping the motor 6 by the brake.
なお、洗濯乾燥機100は、例えば以下に説明するように、乾燥運転のみを行うことができる。
The washer / dryer 100 can only perform a drying operation, for example, as described below.
例えば、使用者が洗濯物を洗濯兼脱水槽4に投入して操作入力部2から乾燥運転の開始を洗濯乾燥機100に指示したとする。すると、図6に示すように、洗濯乾燥機100は、前記したステップS21とステップS37とステップS38の処理のみを行う。
For example, suppose that the user puts the laundry into the washing / dehydrating tub 4 and instructs the washer / dryer 100 to start the drying operation from the operation input unit 2. Then, as shown in FIG. 6, the washer / dryer 100 performs only the processes of step S21, step S37, and step S38 described above.
洗濯乾燥機100は、乾燥運転工程(ステップS37)の水冷除湿給水工程(ステップS37b)から冷却送風工程(ステップS38)までの工程において、水冷部14(冷却部)を経由して冷却水を乾燥ダクト11に送る。水冷部14は、冷却水が少なくとも洗剤投入配管92の途中部分の周囲を流れるように、構成されている。このような水冷部14は、乾燥運転時に外部から供給される冷却水を用いて、洗剤投入配管92と、洗剤投入配管92に溜まっている液剤(洗濯処理液)を冷却することができる。また、水冷部14は、洗剤投入配管92を冷却することで、洗剤投入配管92に繋がっている洗剤タンク91と、洗剤タンク91に溜まっている液剤も冷却することができる。
The washing / drying machine 100 dries the cooling water via the water cooling unit 14 (cooling unit) in the steps from the water-cooled dehumidifying / supplying water step (step S37b) to the cooling air blowing process (step S38) in the drying operation step (step S37). Send to duct 11. The water cooling unit 14 is configured so that the cooling water flows at least around an intermediate portion of the detergent input pipe 92. Such a water cooling unit 14 can cool the detergent input pipe 92 and the liquid agent (washing treatment liquid) accumulated in the detergent input pipe 92 by using the cooling water supplied from the outside during the drying operation. Further, by cooling the detergent input pipe 92, the water cooling unit 14 can also cool the detergent tank 91 connected to the detergent input pipe 92 and the liquid agent accumulated in the detergent tank 91.
また、洗濯乾燥機100は、洗剤タンク91や洗剤自動投入ユニット9を比較的高温になり易い部位(例えば、乾燥運転時に熱源となるヒータ24や、乾燥運転時に温風によって高温化される洗濯兼脱水槽4等)との間に一定以上の距離を確保しなくてもよい。つまり、洗濯乾燥機100は、洗剤タンク91や洗剤自動投入ユニット9を比較的高温になり易い部位に近接して配置できる。そのため、洗濯乾燥機100は、本体サイズ(筐体1のサイズ)を小型化できる。特に洗濯乾燥機100は、縦型式である場合に、本体サイズ(筐体1のサイズ)を小型化できる。
Further, in the washer / dryer 100, the detergent tank 91 and the detergent automatic charging unit 9 are likely to have a relatively high temperature (for example, a heater 24 which is a heat source during the drying operation, and a washing / drying machine where the temperature is raised by warm air during the drying operation. It is not necessary to secure a certain distance or more from the dehydration tank 4 etc.). That is, in the washer / dryer 100, the detergent tank 91 and the detergent automatic charging unit 9 can be arranged close to a portion where the temperature tends to be relatively high. Therefore, the washer / dryer 100 can reduce the size of the main body (the size of the housing 1). In particular, when the washer / dryer 100 is a vertical type, the size of the main body (size of the housing 1) can be reduced.
なお、洗濯乾燥機100は、乾燥運転中に、循環風の温度を循環風温度センサ21で検知したり、洗濯物を通過した後の温風の温度を排水温度センサ23で検知したりすることで、水冷部14の冷却機能(水冷機能)が正常に機能しているか否かを判定することができる。
The washing / drying machine 100 detects the temperature of the circulating air with the circulating air temperature sensor 21 during the drying operation, and detects the temperature of the warm air after passing through the laundry with the drainage temperature sensor 23. Therefore, it can be determined whether or not the cooling function (water cooling function) of the water cooling unit 14 is functioning normally.
以上の通り、本実施形態に係る洗濯乾燥機100によれば、乾燥運転中の熱により洗剤や柔軟剤等の洗濯に用いる液剤の加熱を抑制することができる。
しかも、本実施形態に係る洗濯乾燥機100によれば、ヒータ24(加熱部)の上方に洗剤タンク91(タンク)や洗剤自動投入ユニット9(自動投入部)をヒータ24(加熱部)に近接して配置することができる。そのため、設置面積の増大を抑制することができ、本体(筐体)サイズを小型化させることができる。 As described above, according to the washer /dryer 100 according to the present embodiment, it is possible to suppress the heating of the liquid agent used for washing such as the detergent and the softener due to the heat during the drying operation.
Moreover, according to the washer /dryer 100 according to the present embodiment, the detergent tank 91 (tank) and the detergent automatic charging unit 9 (automatic charging unit) are placed close to the heater 24 (heating unit) above the heater 24 (heating unit). Can be placed. Therefore, it is possible to suppress an increase in the installation area and reduce the size of the main body (housing).
しかも、本実施形態に係る洗濯乾燥機100によれば、ヒータ24(加熱部)の上方に洗剤タンク91(タンク)や洗剤自動投入ユニット9(自動投入部)をヒータ24(加熱部)に近接して配置することができる。そのため、設置面積の増大を抑制することができ、本体(筐体)サイズを小型化させることができる。 As described above, according to the washer /
