The clothes inlet 25 is openably and closably covered by a cover 26. An operation display unit 33 is provided at the rear of the upper housing 24, and a user operates the operation display unit 33 to set a washing course and execute washing.
The control device 27 includes a control unit (not shown) that controls an electric unit such as the motor 20 to perform a series of washing operations such as a washing step, a rinsing step, and a spin-drying step, and the control device 27 is disposed on the back surface of the washing machine main body 11. The control device 27 includes a case 29, a power supply board 28, a metal cover 31, and a noncombustible material sheet 30, which will be described below.
An opening 11a is formed in the back surface of the washing machine main body 11, and a resin cover 32 is attached so as to cover the opening 11 a.
As shown in fig. 2, the insulating incombustible material sheet 30 and the power supply board 28 are housed in a frame 35 of the case 29 formed of flame-retardant ABS.

(washing operation)
The operation of the washing machine 10 configured as described above will be described.
The user opens the lid 26 and puts the laundry into the washing tub 14. The user puts detergent or softener into a predetermined place and starts the washing operation by an activation switch provided in the operation display unit 33. Thereby, the control device 27 starts the cleaning process. The water supply valve (not shown) is opened for a predetermined time to supply the washing water to the washing tub 14. When the washing water reaches a predetermined level, the water supply valve is closed to stop the supply of the water. Then, the controller 27 drives the motor 20 to rotate the pulsator 17, thereby performing the washing process. When the washing process is completed, the dirty washing water is discharged. Then, controller 27 drives motor 20 to rotate washing tub 14 to perform intermediate dewatering, and starts the rinsing process. In the rinsing step, the water supply valve is opened for a predetermined time to supply the washing water to the washing tub 14. When a predetermined water level is reached, the water supply valve is closed to stop the supply of water. The controller 27 drives the motor 20 to rotate the pulsator 17 to perform a rinsing process. When the rinsing step is completed, the dirty washing water is discharged, and controller 27 starts the dehydration step of rotating washing tub 14 by driving motor 20.
The control device 27 drives the motor 20 via the electric components on the power supply board 28 to rotate the pulsator 17. At this time, in the control device 27, electric components (not shown) disposed on the power supply board 28 and through which a high current flows generate heat. Even if the electric components are heated to a high temperature, the temperature in the closed space surrounded by the insulating incombustible material sheet 30 and the metal cover 31 is high, and therefore, the fire is extinguished even when the ignition temperature is reached. In other words, safety can be further ensured in response to a risk of temperature rise of the control device 27.
(action, etc.)
As described above, the washing machine of the present disclosure includes: a washing machine main body 11; a control device 27 vertically disposed on the back side of the washing machine main body 11; and a resin cover 32 that covers the control device 27 and is detachable from the washing machine main body 11. The control device 27 includes: a casing 29 vertically disposed on the back surface of the washing machine main body 11; a power supply board 28 housed in the casing 29 and having a control unit that performs a washing operation including a cleaning step, a rinsing step, and a dehydration step; a metal cover 31 attached to the case 29 so as to cover the power supply board 28; and a non-combustible material sheet 30 housed in the case 29 and disposed between the case 29 and the power supply board 28. The term "vertically" means not only a case where the substrate is completely vertical but also a case where the substrate is substantially vertical.
This makes it possible to cope with the risk of temperature rise of the control device 27, and it is not necessary to use a flame retardant material or a nonflammable material for the resin cover 32, thereby suppressing the manufacturing cost.
As in the above-described embodiment, the power supply board 28 and the incombustible material sheet 30 may be housed in the frame 35 provided in the case 29.
