（洗濯運転）
以上のように構成された洗濯機１０の動作を説明する。 (Washing operation)
The operation of the washing machine 10 configured as described above will be described.

使用者は、蓋体２６を開放し、洗濯物を洗濯槽１４に投入する。使用者は、洗剤や柔軟剤を所定の場所に投入し、操作表示部３３に設けられたスタートスイッチにより洗濯運転を開始する。これにより、制御装置２７は洗い工程を開始する。給水弁（図示せず）が所定時間開成され、洗濯槽１４に洗濯水が供給される。洗濯水が所定の水位に達すると、給水弁が閉成されて給水が休止する。そして、制御装置２７は、モータ２０を駆動してパルセータ１７を回転させて洗い工程を行う。洗い工程が終了すると、汚れた洗濯水が排水される。そして、制御装置２７は、中間脱水を行い、すすぎ工程を開始する。すすぎ工程においては、給水弁が所定時間開成され、洗濯水が洗濯槽１４に供給される。所定の水位に達すると、給水弁が閉成されて給水が休止する。制御装置２７は、モータ２０を駆動してパルセータ１７を回転させてすすぎ工程を行う。すすぎ工程が終了すると、汚れた洗濯水が排水され、制御装置２７は脱水工程を開始する。 The user opens the lid 26 and puts the laundry into the washing tub 14. The user puts a detergent or a softener in a predetermined place, and starts a washing operation by a start switch provided on the operation display unit 33. As a result, the control device 27 starts the washing process. A water supply valve (not shown) is opened for a predetermined time, and washing water is supplied to the washing tub 14. When the washing water reaches a predetermined water level, the water supply valve is closed and the water supply is stopped. Then, the control device 27 drives the motor 20 to rotate the pulsator 17 to perform the washing step. When the washing process is completed, the dirty washing water is drained. Then, the control device 27 performs intermediate dehydration and starts the rinsing process. In the rinsing step, the water supply valve is opened for a predetermined time, and the washing water is supplied to the washing tub 14. When the predetermined water level is reached, the water supply valve is closed and the water supply is stopped. The control device 27 drives the motor 20 to rotate the pulsator 17 to perform the rinsing process. When the rinsing step is completed, the dirty washing water is drained, and the control device 27 starts the dehydration step.

制御装置２７は、電源基板２８上の電装部品を通じて、モータ２０を駆動し、パルセータ１７を回転させる。このとき、制御装置２７において、電源基板２８上に配設されており高電流が流れる電装部品（図示せず）が発熱する。万が一、電装部品より発火が発生した場合も、絶縁性の不燃材シート３０と金属カバー３１に囲まれた閉空間内での発火となるため、窒息消化する。すなわち、制御装置２７の温度上昇のおそれに対し、安全性がより確保される。 The control device 27 drives the motor 20 and rotates the pulsator 17 through the electrical components on the power supply board 28. At this time, in the control device 27, the electrical components (not shown) arranged on the power supply board 28 and through which a high current flows generate heat. In the unlikely event that an ignition occurs from an electrical component, the ignition occurs in a closed space surrounded by the insulating noncombustible material sheet 30 and the metal cover 31, so that the material is suffocated. That is, safety is further ensured against the risk of temperature rise of the control device 27.

（作用等）
以上説明したように、本開示の洗濯機は、本体１１と、本体１１の背面側に垂直に配設されている制御装置２７と、制御装置２７を覆い、本体１１に着脱できる樹脂カバー３２と、を備えている。制御装置２７は、本体１１の背面側に垂直に配設されるケース２９と、洗い工程、すすぎ工程、脱水工程を含む洗濯運転を実行する制御部を備え、不燃材シート３０上に配設される電源基板２８と、電源基板２８を覆い、ケース２９に装着される金属カバー３１とを備えている。制御装置２７は、さらにケース２９に収容され、ケース２９と電源基板２８の間に配設される不燃材シート３０をさらに備えている。なお、「垂直に」とは、完全に垂直であることを意味するだけでなく、実質的に垂直であることも意味する。 (Action, etc.)
As described above, the washing machine of the present disclosure includes a main body 11, a control device 27 vertically arranged on the back side of the main body 11, and a resin cover 32 that covers the control device 27 and can be attached to and detached from the main body 11. , Is equipped. The control device 27 includes a case 29 arranged vertically on the back side of the main body 11 and a control unit for executing a washing operation including a washing step, a rinsing step, and a dehydrating step, and is arranged on the noncombustible material sheet 30. A power supply board 28 and a metal cover 31 that covers the power supply board 28 and is mounted on the case 29 are provided. The control device 27 is further housed in a case 29 and further includes a noncombustible material sheet 30 disposed between the case 29 and the power supply board 28. Note that "vertically" not only means that it is completely vertical, but also that it is substantially vertical.

これにより、制御装置の温度上昇のおそれに対処でき、樹脂カバーを難燃性または不燃材料とする必要がなくなり製造コストを抑制できる。 As a result, the risk of temperature rise of the control device can be dealt with, the resin cover does not need to be a flame-retardant or non-flammable material, and the manufacturing cost can be suppressed.

また、上記実施形態のように、電源基板２８と不燃材シート３０は、ケース２９に設けられている枠体３５内に収容されてもよい。 Further, as in the above embodiment, the power supply board 28 and the noncombustible material sheet 30 may be housed in the frame body 35 provided in the case 29.

これにより、製造効率が向上する。 This improves the manufacturing efficiency.

以上のように、本開示の洗濯機は、制御装置の温度上昇に対して製品の安全性をより確保できる構成であるため、洗濯機本体に着脱する樹脂カバーは、難燃性材料または不燃材料とする必要がない。したがって、サイズが大型になった場合でも、製造コストを抑制できる。 As described above, since the washing machine of the present disclosure has a configuration that can further ensure the safety of the product against the temperature rise of the control device, the resin cover attached to and detached from the washing machine body is made of a flame-retardant material or a non-flammable material. There is no need to. Therefore, even if the size becomes large, the manufacturing cost can be suppressed.
