Description

本発明は、洗濯機の水槽の傾斜角度検出方法に関するものである。 The present invention relates to a method for detecting a tilt angle of a water tank of a washing machine.

一般に、洗濯機は外箱内にその四隅から吊下げ手段によって水槽を吊下げ、底部に攪拌翼を配設した洗濯兼脱水槽を前記水槽内に配設し、洗濯兼脱水槽の下方にギヤ、クラッチなどの機構を介してモータを配設したもので、外箱の上部の四隅部から、吊り棒を主体とし下部に防振部分を有する吊下げ手段によって水槽が吊持されている。 In general, a washing machine suspends a water tub from its four corners in an outer box by means of suspending, a washing / dehydration tub having a stirring blade at the bottom is provided in the water tub, and a gear below the washing / dehydration tub. The water tank is suspended from the four corners of the upper part of the outer box by suspension means having a suspension rod as a main body and a vibration-proof part at the lower part.

そして、洗濯行程や脱水行程では洗濯物である衣類の洗濯兼脱水槽内での片寄りによるアンバランスによって、洗濯兼脱水槽や水槽に大きな振動が発生するが、防振部分を備える吊り棒によってこの振動が外箱に伝わらないようにしている。 And in the washing process and dehydration process, large vibrations are generated in the washing and dehydrating tub and the water tank due to the imbalance due to the misalignment in the washing and dehydrating tank of the clothes that are the laundry, This vibration is prevented from being transmitted to the outer box.

ところで、近年、乾燥手段を備えた洗濯乾燥機が出現している。この洗濯乾燥機においても、通常の洗濯機と同じく、洗濯兼脱水槽の形状は鉛直方向に長い円筒型で、かつ、洗濯兼脱水槽の回転中心軸が鉛直方向を向いているため、洗濯乾燥時において衣類の鉛直方向への回転移動が少なくなる傾向にあり、その結果、衣類が洗濯兼脱水槽内で上下方向に入れ替りにくくなって、衣類に皺が生じたり、乾燥ムラが生じたりしやすかった。 By the way, in recent years, a washing dryer having a drying means has appeared. Also in this washing and drying machine, the shape of the washing and dewatering tub is a cylindrical shape that is long in the vertical direction, and the rotation center axis of the washing and dehydrating tub is oriented in the vertical direction, so that the washing and drying tank is washed and dried. There is a tendency that the rotational movement of the clothes in the vertical direction tends to be less at times, and as a result, it becomes difficult for the clothes to change up and down in the washing and dewatering tank, and the clothes are likely to wrinkle and dry unevenness. It was.

また、洗い行程でも、ほとんどが水平方向の単純な水流であり、洗浄効果が十分ではなかった。 In addition, most of the washing process was a simple horizontal water flow, and the washing effect was not sufficient.

さらに、洗濯兼脱水槽が長い円筒型であるため、このような形状の槽が垂直に配設されていると、槽内の衣類を取出す際、特に底部のものを取出しにくく、使い勝手がよくなかった。 Furthermore, since the washing and dewatering tub is a long cylindrical shape, when the tub with such a shape is arranged vertically, it is difficult to take out the bottom of the garment in the tub. It was.

そこで、かかる不都合を解消するものとして、乾燥行程時には洗濯兼脱水槽内の衣類が上下方向に入れ替りやすく、衣類に皺が生じたり、乾燥ムラが発生することを防止でき、また、洗い行程では水流を複雑にできてよりいっそうの洗浄効果が期待でき、さらに洗濯兼脱水槽内からの衣類の取出し作業を行いやすくできる洗濯機が提案された。 Therefore, in order to eliminate such inconvenience, clothes in the washing / dehydrating tub can be easily changed in the vertical direction during the drying process, so that wrinkles and drying unevenness can be prevented from occurring in the washing process. A washing machine has been proposed that can be made more complex and can be expected to have a higher cleaning effect, and can easily carry out the work of taking out clothes from the washing and dewatering tank.

これは、外箱内にその四隅から吊下げ手段によって水槽を吊下げ、底部に攪拌翼を配設した洗濯兼脱水槽を前記水槽内に配設し、洗濯兼脱水槽の下方にギヤ、クラッチなどの機構を介してモータを配設した洗濯乾燥機において、前記吊下げ手段は、下部に防振部分を有する吊り棒の上部に雄ネジ部分を形成し、この雄ネジ部分を駆動部で回転する雌ネジ回転体にねじ込んで吊下げ長さを調整可能としたものである。 This is because the water tank is suspended from the four corners in the outer box by means of suspension, a washing and dewatering tank having a stirring blade at the bottom is disposed in the water tank, and a gear and clutch are provided below the washing and dewatering tank. In the washing / drying machine in which the motor is arranged through a mechanism such as the above, the suspension means forms a male screw part on the upper part of the suspension rod having a vibration-proof part in the lower part, and the male screw part is rotated by the drive part. The hanging length can be adjusted by screwing into the female screw rotating body.

これにより、水槽は四隅のうちの全部または一部を吊下げ長さを自動調整可能とした吊り棒による吊下げ手段を介して外箱から吊下げられるから、この吊下げ長さを変えることで外箱内で水槽が傾斜する。よって、洗濯兼脱水槽の回転中心軸が鉛直方向ではなく、斜め方向となるから、乾燥行程時には洗濯兼脱水槽内の衣類が鉛直方向に回転移動しやすくなり、皺の発生や乾燥ムラを抑えることができる。 As a result, the aquarium can be suspended from the outer box by means of suspension means with suspension bars that can automatically adjust the suspension length of all or part of the four corners. The water tank is tilted inside the outer box. Therefore, the center axis of rotation of the washing / dehydrating tub is not in the vertical direction, but in an oblique direction, so that the clothes in the washing / dehydrating tub can be easily rotated in the vertical direction during the drying process, and generation of wrinkles and drying unevenness is suppressed. be able to.

また、洗い行程でも洗濯兼脱水槽の回転中心軸が斜め方向となることで、水流が複雑となって洗浄効果が増大する。 In addition, since the rotation center axis of the washing / dehydrating tank is inclined in the washing process, the water flow becomes complicated and the washing effect is increased.

さらに、水槽を手前に傾斜させることで、洗濯兼脱水槽内の衣類を取出す際に槽の上部開口面が使用者の方に斜めに向き、洗濯兼脱水槽の手前の高さが低くなる。これにより、槽内を見易くなって、衣類の取出し作業が行い易くなる。 Further, by tilting the water tank forward, the upper opening surface of the tank faces obliquely toward the user when taking out the clothes in the washing / dehydration tank, and the height in front of the washing / dehydration tank is lowered. Thereby, it becomes easy to see the inside of a tank and it becomes easy to take out clothing.

前記のように水槽を傾斜させる洗濯機は、例えば０〜２０度の範囲で水槽が傾斜するが、傾斜角度は例えば０度か、または２０度のいずれにしか設定されていない。 In the washing machine for tilting the water tank as described above, for example, the water tank is tilted in the range of 0 to 20 degrees, but the tilt angle is set to only 0 degrees or 20 degrees, for example.

一方、乾燥行程、洗い行程または衣類の取出し作業時などでは、最適な傾斜角度がそれぞれ異なり、また、使用者の身長などの条件によっても最適な傾斜角度は異なる。 On the other hand, in the drying process, the washing process, or the work of taking out clothes, the optimum inclination angle differs, and the optimum inclination angle also varies depending on conditions such as the height of the user.

しかしながら、前記洗濯機では、傾斜角度が一律に設定されているため、使用者の要求に対応しきれなかった。かかる不都合を解消するには、水槽の傾斜角度を無段階で可変設定できることが望まれるが、例えば単純にスイッチで検出する方法ではスイッチの数が制限されるため、実現が困難であり、また、スイッチの数が増加する分だけコストアップするという問題もあった。 However, in the washing machine, since the inclination angle is set uniformly, the washing machine cannot meet the user's request. In order to eliminate such inconvenience, it is desirable that the inclination angle of the water tank can be variably set in a stepless manner. However, for example, the method of simply detecting with a switch limits the number of switches, and is difficult to realize. There has also been a problem that the cost increases as the number of switches increases.

本発明は前記従来例の不都合を解消するものとして、水槽を傾斜角度調整自在に配設する場合に、無段階に傾斜角度を検出でき、運転条件などによって自由に希望の傾斜角度を設定できて最適な水槽傾斜角度での運転が可能となる洗濯機を提供することを目的とする。 The present invention eliminates the inconvenience of the conventional example, and when the water tank is arranged so that the tilt angle can be adjusted, the tilt angle can be detected in a stepless manner, and the desired tilt angle can be freely set according to operating conditions. An object of the present invention is to provide a washing machine that can be operated at an optimal water tank inclination angle.

本発明は前記目的を達成するものとして、外箱内にその四隅から吊下げ手段によって水槽を吊下げ、底部に攪拌翼を配設した洗濯兼脱水槽を前記水槽内に配設し、洗濯兼脱水槽の下方にギヤ、クラッチなどの機構を介してモータを配設した洗濯機において、前記吊下げ手段は、下部に防振部分を有する吊り棒の上部に雄ネジ部分を形成し、この雄ネジ部分を駆動部で回転する雌ネジ回転体にネジ込んで吊下げ長さを調整可能とするとともに、前記雄ネジ部分の外周面に摺動抵抗器を当接させ、この摺動抵抗器で検出される抵抗値の変化をもとに検出される雄ネジ部分の移動量から水槽の傾斜角度を検出することを特徴とする。 In order to achieve the above object, the present invention provides a washing / dehydration tub in which a water tub is suspended from the four corners of the outer box by means of suspending and a stirring blade is disposed at the bottom in the water tub. In a washing machine in which a motor is disposed below a dewatering tank via a mechanism such as a gear and a clutch, the suspension means forms a male screw portion on the upper portion of a suspension rod having a vibration-proof portion on the lower portion, and this male The threaded portion is screwed into a female screw rotating body that is rotated by a drive unit, so that the suspension length can be adjusted, and a sliding resistor is brought into contact with the outer peripheral surface of the male threaded portion. The inclination angle of the water tank is detected from the amount of movement of the male screw portion detected based on the detected change in resistance value.

本発明の洗濯機は、吊下げ手段の下部に防振部分を有する吊り棒の上部に雄ネジ部分を形成し、この雄ネジ部分を駆動部で回転する雌ネジ回転体にネジ込んで吊下げ長さを調整可能とするとともに、前記雄ネジ部分の外周面に摺動抵抗器を当接させ、この摺動抵抗器で検出される抵抗値の変化をもとに検出される雄ネジ部分の移動量から水槽の傾斜角度が検出される。検出される傾斜角度は雌ネジ回転体の回転角度に対応するものであるから、無段階的なものであり、任意の傾斜角度を検出でき、設定できる。 In the washing machine of the present invention, a male thread part is formed on the upper part of a suspension rod having a vibration isolating part at the lower part of the suspension means, and the male thread part is screwed into a female thread rotating body rotated by a drive unit. The length can be adjusted, and a sliding resistor is brought into contact with the outer peripheral surface of the male screw portion, and the male screw portion detected based on the change in the resistance value detected by the sliding resistor. The tilt angle of the water tank is detected from the amount of movement. Since the detected inclination angle corresponds to the rotation angle of the female screw rotating body, it is stepless, and an arbitrary inclination angle can be detected and set.

以下、図面について本発明の実施形態を詳細に説明する。図１は本発明の洗濯機の実施形態を示す側面側の説明図、図２は同上平面側の説明図、図３は同上要部である吊下げ手段の縦断正面図で、洗濯機の全体構成は既に説明したとおり、洗濯機は外箱１内にその四隅から吊下げ手段１４によって水槽３を吊下げ、図示は省略するが底部に攪拌翼を配設した洗濯兼脱水槽を前記水槽３内に配設し、洗濯兼脱水槽の下方にギヤ、クラッチなどの機構を介してモータ３３を配設している。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an explanatory view of a side surface showing an embodiment of the washing machine of the present invention, FIG. 2 is an explanatory view of a plane side of the same, and FIG. 3 is a longitudinal front view of a hanging means which is a main part of the same. As already described, the washing machine suspends the water tub 3 from the four corners of the washing machine 1 by the suspending means 14 in the outer box 1, and although not shown, the washing and dewatering tub provided with a stirring blade at the bottom is the water tub 3. A motor 33 is disposed below the washing and dewatering tub via a mechanism such as a gear and a clutch.

本発明は吊下げ手段１４として、図１に示すように、下部に防振部分１５を組み込んだ吊り棒５の上部に雄ネジ１６の部分を形成し、この雄ネジ１６の部分を駆動部１７で回転する雌ネジ回転体１８にねじ込んで吊下げ長さを自動調整可能とした。 In the present invention, as the suspending means 14, as shown in FIG. 1, a male screw 16 part is formed on the upper part of the suspension bar 5 incorporating a vibration isolating part 15 at the lower part, and this male screw 16 part is used as the drive unit 17. The hanging length can be automatically adjusted by screwing into the female screw rotating body 18 that rotates at the same time.

駆動部１７はＤＣモータによるもの、雌ネジ回転体１８はこのモータに歯合する嵌合歯車によるものであるが、これら駆動部１７と雌ネジ回転体１８とで駆動ユニット（アクチュエーター）１９が形成され、吊り棒５の上部にこれが一体物として組み込まれる。 The driving unit 17 is a DC motor, and the female screw rotating body 18 is a fitting gear that meshes with the motor. The driving unit 17 and the female screw rotating unit 18 form a driving unit (actuator) 19. This is incorporated as an integral part on the upper part of the suspension bar 5.

図中２０、２１は駆動ユニット（アクチュエーター）１９の上下位置で吊り棒５の駆動部分を埃や水分から保護する密閉ケースとしての防塵ケース、２２は駆動ユニット（アクチュエーター）１９の下面に形成する球面座である。 In the figure, reference numerals 20 and 21 denote dust-proof cases as a sealed case for protecting the drive portion of the suspension bar 5 from dust and moisture at the upper and lower positions of the drive unit (actuator) 19, and 22 a spherical surface formed on the lower surface of the drive unit (actuator) 19. The seat.

雄ネジ１６は金属製である吊り棒５に膨径部を設けて直接これに形成してもよいが、この雄ネジ１６を合成樹脂製の外周ネジ管とし、これに吊り棒５の本体に被嵌して形成するようにしてもよい。 The male screw 16 may be formed directly on the suspension rod 5 made of metal by providing an enlarged diameter portion. However, the male screw 16 is a synthetic resin outer peripheral screw tube, which is attached to the body of the suspension rod 5. You may make it form by fitting.

そして、前記球面座２２を外箱１の内側に突出させたフランジ状の吊り板２４の球形凹部（図示せず）に嵌合させ、防振部分１５を水槽３の側部から側方に突出させたフランジ２５に係止する。これにより、吊下げ手段１４が外箱１と水槽３との間に懸架される。 Then, the spherical seat 22 is fitted into a spherical recess (not shown) of a flange-like suspension plate 24 that protrudes to the inside of the outer box 1, and the vibration isolation portion 15 protrudes from the side of the water tank 3 to the side. The flange 25 is locked. Thereby, the suspending means 14 is suspended between the outer case 1 and the water tank 3.

本発明の駆動ユニット（アクチュエーター）１９を組み込んだ吊下げ手段１４は外箱１内の四隅に配置されるが、図１の例は図２に示すように四隅の全てに本発明の構成による吊下げ手段１４を配置する場合である。 The suspending means 14 incorporating the drive unit (actuator) 19 of the present invention is arranged at the four corners in the outer box 1, but the example of FIG. 1 is suspended at all four corners according to the configuration of the present invention as shown in FIG. This is a case where the lowering means 14 is arranged.

本発明はかかる構成に加えて、水槽３の傾斜角度を検出する方法の第１実施形態として図３に示すように、吊り棒５の上部に形成した雄ネジ１６の部分の外周面に摺動抵抗器２７を当接させている。これにより、駆動部１７の駆動により雌ネジ回転体１８が回転駆動すると、これに嵌合している雄ネジ１６が上下動し、吊り棒５も上下動するが、このとき雄ネジ１６の上下動を摺動抵抗器２７が抵抗値の変化で検出する。 In addition to such a configuration, the present invention slides on the outer peripheral surface of the male screw 16 formed on the upper part of the suspension bar 5 as shown in FIG. 3 as a first embodiment of the method for detecting the inclination angle of the water tank 3. The resistor 27 is in contact. As a result, when the female screw rotating body 18 is driven to rotate by driving of the driving unit 17, the male screw 16 fitted to the female screw 16 moves up and down, and the suspension bar 5 also moves up and down. The sliding resistor 27 detects the movement by a change in the resistance value.

抵抗値の変化は移動量により変化するものであり、よって、この抵抗値の変化をもって移動距離を算出し、吊り棒５の移動距離が検出できる。 The change in the resistance value changes depending on the amount of movement. Therefore, the movement distance can be calculated based on the change in the resistance value, and the movement distance of the suspension bar 5 can be detected.

第２実施形態は駆動ユニット（アクチュエーター）１９の駆動部１７への通電時間を測定し、この通電時間から吊り棒５の移動距離を推定して検出する。通電時間は例えば水が多いと長い時間を要するなど、水位や衣類の量などによって左右されるが、このような変化する条件は経験則により予め記憶させ設定しておくことで、概略の推定は可能となる。 In the second embodiment, the energization time to the drive unit 17 of the drive unit (actuator) 19 is measured, and the moving distance of the suspension bar 5 is estimated and detected from this energization time. The energization time depends on the water level and the amount of clothing, for example, it takes a long time if there is a lot of water. It becomes possible.

第３実施形態は、図４に示すように四隅の吊下げ手段１４の下部に形成される防振部分１５または水槽３本体の下部に超音波センサーなどを使用する位置センサー２８を取り付け、この位置センサー２８で防振部分１５または水槽３本体の下部と洗濯機底枠２９との間の距離を測定し、防振部分１５または水槽３本体の下部と洗濯機底枠２９との位置関係の変位量から水槽３の傾斜角度を検出する。 In the third embodiment, as shown in FIG. 4, a position sensor 28 using an ultrasonic sensor or the like is attached to the vibration-proof portion 15 formed at the lower part of the hanging means 14 at the four corners or the lower part of the main body of the water tank 3. The distance between the vibration isolating portion 15 or the lower part of the water tub 3 main body and the washing machine bottom frame 29 is measured by the sensor 28, and the positional relationship between the vibration isolating part 15 or the water tank 3 main body and the washing machine bottom frame 29 is changed. The inclination angle of the water tank 3 is detected from the amount.

第４実施形態は第３実施形態の位置センサー２８に替えて重量センサー３０を取り付けた。水槽３が傾斜すると、水槽３の四隅における水位が変化し、その結果、四隅に配設されている重量センサー３０に加わる水の重量も変化する。よって、この重量センサー３０で検出される水の重量値の変化をもって水槽３の傾斜角度を検出する。 In the fourth embodiment, a weight sensor 30 is attached in place of the position sensor 28 of the third embodiment. When the water tank 3 is inclined, the water levels at the four corners of the water tank 3 change, and as a result, the weight of water applied to the weight sensor 30 disposed at the four corners also changes. Therefore, the inclination angle of the water tank 3 is detected based on the change in the weight value of the water detected by the weight sensor 30.

第５実施形態は図５に示すように、洗濯機には、水槽３内の水位を検出する水位センサー３２が配設されているが、この水位センサー３２は、水槽３の下部に開口する導圧チューブ３１の上端に接続されている。 As shown in FIG. 5, in the fifth embodiment, the washing machine is provided with a water level sensor 32 that detects the water level in the water tank 3. The water level sensor 32 is a guide that opens at the bottom of the water tank 3. It is connected to the upper end of the pressure tube 31.

この第５実施形態では、この水位センサー３２を利用して水槽３の傾斜角度を検出するもので、図５に示すように水槽３が傾斜すると導圧チューブ３１が開口している部位における水槽３の底部と水面との距離、すなわち水位が変化する。よってこの水位変化を水位センサー３２で検出し、この水位変化から水槽の傾斜角度を検出するようにした。 In the fifth embodiment, the water level sensor 32 is used to detect the tilt angle of the water tank 3, and when the water tank 3 is tilted as shown in FIG. 5, the water tank 3 at the site where the pressure guiding tube 31 is open. The distance between the bottom of the water and the water surface, that is, the water level changes. Therefore, this water level change is detected by the water level sensor 32, and the inclination angle of the water tank is detected from this water level change.

以上のようにして水槽３の傾斜角度を０度から最大角度、例えば２０度の範囲で任意に検出して設定できるから、乾燥行程、洗い行程、脱水行程や衣類の洗濯兼脱水槽内からの取出し作業時など、運転条件によって求められる最適な水槽の傾斜角度を得ることができる。 As described above, since the inclination angle of the water tank 3 can be arbitrarily detected and set within a range of 0 degree to the maximum angle, for example, 20 degrees, the drying process, the washing process, the dehydration process, and the clothes washing / dehydrating tank from the inside. It is possible to obtain the optimum water tank inclination angle required by operating conditions, such as during take-out work.
