【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. The same components as those of the conventional example are designated by the same reference numerals and the description thereof will be omitted.

As shown in FIGS. 1 and 2, a water receiving tank 2 suspended and supported in an outer tank 1, a washing / dewatering tank 3 and a stirring blade 4 rotatably disposed in the water receiving tank 2, and Outside the water receiving tank 2, a speed reducing mechanism section 5 for driving the stirring blade 4 arranged in the center of the water receiving tank 2, a motor 6 for transmitting a driving force to the speed reducing mechanism section 5, and water supply to the water receiving tank 2. Water supply valve 7, drainage valve 8 for draining the wash water in the water receiving tub 2, a control device 9 for controlling the motor 6, the water supply valve 7, and the drainage valve 8, the motor 6, the water supply valve 7, and the drainage valve 8 and the control device 9 and the like, the power supply transformer 10 of the input power supply to the electrical components, the power supply transformer 10 is a box-shaped waterproof cover 11 having a top surface with the lower part opened, and the waterproof cover 11 And cover it with a waterproof cover lid 12 which is attached from below, and 13 is for input to the power transformer 10 and It is a lead sen for output, and the waterproof cover 11 and the waterproof cover lid 12 are formed of a flame-retardant resin, and the contact portion of the lead sen 13 of the waterproof cover lid 12 is thinned to form a comb 14. It is arranged in the outer tank 1.

Next, the operation of this embodiment will be described. It is not necessary to configure all the electric components used such as the motor 6, the water supply valve 7, the drain valve 8 and the control device 9 according to the overseas voltage specifications. For each electric component, regarding product pressure and winding specifications There is no need to consider and develop. Conventionally, since the motor 6 and the control device 9 differ depending on the product, they were configured according to the overseas voltage specifications (for example, 110V, 120V, 220V, 240V) for each product development. By using the transformer 10, it is not necessary to support the voltage of the motor 6 and the control device 9.

As described above, according to this embodiment, by mounting the power supply transformer 10 of the input power supply, it becomes possible to cope with the overseas voltage specifications, and the development schedule can be shortened. Here, the power supply transformer 10 of the input power supply may correspond to 110V, 120V, 220V, and 240V, respectively, according to overseas voltage specifications, and may be divided into low voltage and high voltage. You may respond.

Further, the waterproof cover 11 and the waterproof cover lid 12 are formed of a flame-retardant resin, and the lower portion of the waterproof cover 11 is opened to form a box having a top surface. By disposing the contact portion in a comb shape 14 in the outer tub 1, insulation deterioration due to washing water during normal use is prevented, and a fire does not occur. By making the comb shape 14, the water splashing from the floor does not need to enter the waterproof cover 11. Here, by providing the corner R at the contact portion of the lead sen 13 on the end surface of the comb-shaped 14, the occurrence of the breakage of the lead sen 13 due to the dehydration vibration of the electric washing machine is also eliminated. Since the waterproof cover 11 and the waterproof cover lid 12 are made of a flame-retardant resin and made of a metal cover, noise due to vibration during washing and dehydration of the electric washing machine can be prevented and the metal cover (the waterproof cover 11 and It is possible to eliminate noise caused by hitting the waterproof cover lid 12) and the metal and the resin (the power source transformer 10) to reduce noise.

[0013]

[Effect of device]

 As is apparent from the above description of the embodiments, the present invention does not require that all the electrical components used such as the motor, the water supply valve, the drain valve, and the control device are configured according to the overseas voltage specifications. It is not necessary to study and develop the product pressure and winding specifications for the electrical components of. Conventionally, since the motors and control devices differ depending on the product, they were configured according to the overseas voltage specifications (for example, 110V, 120V, 220V, 240V) for each product development. By using a transformer, it is not necessary to support the voltage of the motor or control device. Also, the waterproof cover and the waterproof cover lid are made of flame-retardant resin, the contact part of the lead cover on the waterproof cover lid is thinned, and it is placed in the outer tub in the shape of a comb to wash it during normal use. It is possible to prevent insulation deterioration due to water, prevent fires, and reduce noise.
