以下、本発明の実施の形態について、図面を参照しながら説明する。なお、従来例と同じ構成のものは同一符号を付して説明を省略する。また、この実施の形態によって本発明が限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, the same structure as a prior art example attaches | subjects the same code | symbol, and abbreviate | omits description. Further, the present invention is not limited by this embodiment.

（実施の形態１）
図１は、本発明の実施の形態１における洗濯機の操作装置を搭載した洗濯機の構成を示す図、図２は、同洗濯機の操作装置の操作手段を示す図、図３、図４、図５、図６は、洗濯機の各動作状態における静電容量式のタッチスイッチの静電容量の変化を模式的に示した図である。 (Embodiment 1)
FIG. 1 is a diagram showing a configuration of a washing machine equipped with an operation device for a washing machine according to Embodiment 1 of the present invention, FIG. 2 is a diagram showing an operation means of the operation device for the washing machine, and FIGS. FIG. 5 and FIG. 6 are diagrams schematically showing changes in capacitance of the capacitive touch switch in each operation state of the washing machine.

図１および図２において、給水手段１や洗濯脱水槽４が動作していない状態で、かつ操作手段２が操作されていない状態では、タッチスイッチ１１〜１４のそれぞれの一対の電極間の静電容量の変化値は、図３のように変化値はない状態である。使用者がタッチスイッチ１１に触れると変化値は図４のようになり、タッチスイッチ１１の変化値が判定値２１以上になると、操作手段２は、タッチスイッチ１１が操作されたと判断する。   1 and 2, when the water supply means 1 and the washing / dehydrating tub 4 are not operating and the operation means 2 is not operated, the electrostatic capacitance between each pair of electrodes of the touch switches 11 to 14 can be obtained. The change value of the capacitance is in a state where there is no change value as shown in FIG. When the user touches the touch switch 11, the change value is as shown in FIG. 4. When the change value of the touch switch 11 reaches the determination value 21 or more, the operation unit 2 determines that the touch switch 11 has been operated.

電磁弁で構成された給水手段１やモーターによって回転する洗濯脱水槽４が操作手段２の近傍で動作すると、操作手段２が操作されていない状態でもモーターや電磁弁から発生される電界の影響を受けて、タッチスイッチ１１〜１４の静電容量の変化値は、図５のように、判定値２１に近くなり、また、操作手段２周辺の電界の強さによっては、判定値２１を超えて操作手段２が操作されたと誤判断する可能性がある。   When the water supply means 1 constituted by a solenoid valve or the washing and dewatering tub 4 rotated by the motor operates in the vicinity of the operation means 2, the influence of the electric field generated from the motor or the solenoid valve is affected even when the operation means 2 is not operated. In response, the capacitance change value of the touch switches 11 to 14 is close to the determination value 21 as shown in FIG. 5, and exceeds the determination value 21 depending on the strength of the electric field around the operation means 2. There is a possibility that it is erroneously determined that the operation means 2 has been operated.

そこで、本実施の形態の洗濯機の操作装置においては、洗濯機の動作モードに応じて操作有無の判定値を変化させる。すなわち、給水手段１や洗濯脱水槽４が動作中はタッチスイッチ１１〜１４の変化値に対する判定値を上記の判定値２１よりも大きな判定値２２に変更する。この状態で使用者がタッチスイッチ１１に触れると、タッチスイッチ１１の変化値は、給水手段１や洗濯脱水槽４が発生する電界の影響を受けて、図４に比べて図６のように大きくなるため、判定値２２以上になり、操作手段２は、タッチスイッチ１１が操作されたと正しく判断できる。また、操作されていないタッチスイッチ１２〜１４が操作されたと誤検知されることもない。   Therefore, in the operating device for the washing machine according to the present embodiment, the determination value for the presence / absence of the operation is changed according to the operation mode of the washing machine. That is, while the water supply means 1 and the washing / dehydrating tub 4 are in operation, the determination value for the change value of the touch switches 11 to 14 is changed to the determination value 22 larger than the determination value 21 described above. When the user touches the touch switch 11 in this state, the change value of the touch switch 11 is influenced by the electric field generated by the water supply means 1 and the washing / dehydrating tub 4, and is larger as shown in FIG. 6 than FIG. Therefore, the determination value is 22 or more, and the operation means 2 can correctly determine that the touch switch 11 has been operated. Further, it is not erroneously detected that the touch switches 12 to 14 that are not operated are operated.

これにより、電界の影響を受けたタッチスイッチ１１〜１４の変化値と判定値が離れるため、タッチスイッチの誤検知を防止できる。   Thereby, since the change value and the determination value of the touch switches 11 to 14 affected by the electric field are separated, erroneous detection of the touch switch can be prevented.

なお、タッチスイッチ１１〜１４の静電容量の変化値の判断は、判断回路を操作手段２に備え、操作手段２によって行う構成としたが、洗濯機の運転を制御する制御手段６に判断回路を備え、制御手段６によって行ってもよい。   Note that the determination of the capacitance change values of the touch switches 11 to 14 is performed by the operation unit 2 and the determination unit includes the determination circuit. However, the determination circuit is included in the control unit 6 that controls the operation of the washing machine. And may be performed by the control means 6.

FIG. 1 is a diagram showing a configuration of a washing machine equipped with an operation device for a washing machine according to Embodiment 2 of the present invention, FIG. 2 is a diagram showing an operation means of the operation device for the washing machine, and FIGS. These are the figures which showed typically the change of the electrostatic capacitance of the electrostatic capacitance type touch switch in each operation state of a washing machine.

図１および図２において、操作手段２の近傍で強い電界が発生すると、操作手段２が操作されていない状態でも発生した電界の影響を受けて、タッチスイッチ１１〜１４の静電容量の変化値は図７のようになる。   1 and 2, when a strong electric field is generated in the vicinity of the operation unit 2, the change value of the capacitance of the touch switches 11 to 14 is affected by the generated electric field even when the operation unit 2 is not operated. Is as shown in FIG.

このとき、タッチスイッチ１１〜１４の内の複数のスイッチの変化値が基準値３１以上であると、判定値を判定値２１よりも大きな判定値２２に変更する。この状態で使用者がタッチスイッチ１１に触れると、タッチスイッチ１１の変化値は、発生した電界の影響を受けて、電界の影響を受けていないときよりも図８のように大きくなるため、判定値２２以上になり、操作手段２はタッチスイッチ１１が操作されたと正しく判断できる。また、操作されていないタッチスイッチ１２〜１４が操作されたと誤検知されることもない。   At this time, if the change values of the plurality of switches among the touch switches 11 to 14 are the reference value 31 or more, the determination value is changed to a determination value 22 that is larger than the determination value 21. When the user touches the touch switch 11 in this state, the change value of the touch switch 11 is influenced by the generated electric field and becomes larger as shown in FIG. 8 than when it is not affected by the electric field. Since the value is 22 or more, the operation means 2 can correctly determine that the touch switch 11 has been operated. Further, it is not erroneously detected that the touch switches 12 to 14 that are not operated are operated.

これにより、電界の影響を受けたタッチスイッチ１１〜１４の変化値と判定値が離れるため、タッチスイッチの誤検知を防止できる。   Thereby, since the change value and the determination value of the touch switches 11 to 14 affected by the electric field are separated, erroneous detection of the touch switch can be prevented.

図１は、本発明の実施の形態３における洗濯機の操作装置を搭載した洗濯機の構成を示す図、図２は、同洗濯機の操作装置の操作手段を示す図、図７、図８は、洗濯機の各動作状態における静電容量式のタッチスイッチの静電容量の変化を模式的に示した図である。 (Embodiment 3)
FIG. 1 is a diagram showing a configuration of a washing machine equipped with an operation device for a washing machine according to Embodiment 3 of the present invention, FIG. 2 is a diagram showing an operation means of the operation device for the washing machine, and FIGS. These are the figures which showed typically the change of the electrostatic capacitance of the electrostatic capacitance type touch switch in each operation state of a washing machine.

図１および図２において、操作手段２の近傍で強い電界が発生すると、操作手段２が操作されていない状態でも、発生した電界の影響を受けてタッチスイッチ１１〜１４の静電容量の変化値は、図７のようになる。   1 and 2, when a strong electric field is generated in the vicinity of the operation means 2, even if the operation means 2 is not operated, the change value of the capacitance of the touch switches 11 to 14 is affected by the generated electric field. Is as shown in FIG.

この状態で、使用者がタッチスイッチ１１に触れて変化値が図８のように判定値２１以上になったときに、タッチスイッチ１２〜１４の内の複数のスイッチの変化値が基準値３１以上であると、判定値を判定値２１よりも大きな判定値２２に変更する。判定値を判定値２２に変更した後でも、タッチスイッチ１１の変化値が判定値２２以上の場合には、操作手段２は、タッチスイッチ１１が操作されたと判断する。   In this state, when the user touches the touch switch 11 and the change value becomes the determination value 21 or more as shown in FIG. 8, the change values of the plurality of switches among the touch switches 12 to 14 are the reference value 31 or more. If so, the determination value is changed to a determination value 22 larger than the determination value 21. Even after changing the determination value to the determination value 22, if the change value of the touch switch 11 is equal to or greater than the determination value 22, the operation unit 2 determines that the touch switch 11 has been operated.

これにより、電界の影響を受けたタッチスイッチ１１〜１４の判定値が大きくなるためタッチスイッチの誤検知を防止できる。   Thereby, since the judgment values of the touch switches 11 to 14 affected by the electric field are increased, erroneous detection of the touch switch can be prevented.

以上のように、本発明にかかる洗濯機の操作装置は静電容量式のタッチスイッチの判定値を操作手段周辺の電界変化によって変化させることにより、タッチスイッチへの電界の影響を減らすことができ、静電容量方式タッチスイッチの誤検知を防止することができるので、静電容量方式タッチスイッチを採用した洗濯機の操作装置等として有用である。   As described above, the operation device of the washing machine according to the present invention can reduce the influence of the electric field on the touch switch by changing the determination value of the capacitive touch switch according to the electric field change around the operation means. Since it is possible to prevent erroneous detection of the capacitive touch switch, it is useful as an operating device for a washing machine that employs the capacitive touch switch.
