[0008]

[Action]

 As described above, according to the present invention, it is not necessary to configure all the electric components used such as the motor 6, the water supply valve 7, the drainage valve 8 and the control device 9 in accordance with the overseas voltage specifications. It is not necessary to study and develop the product pressure and winding specifications for electrical components. Further, conventionally, the motor 6 and the control device 9 are different depending on the product. Therefore, each product development is configured according to the overseas voltage specifications (for example, 110V, 120V, 220V, 240V). By using the power transformer, it is not necessary to support the voltage of the motor 6 and the control device 9.

【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 Cover with a waterproof cover lid 12 which is attached from below, and the waterproof cover 11 and the waterproof cover lid 12 Is formed of a flame-retardant resin and disposed in the outer tub 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. 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 waterproof cover 11 is opened downward to form a box having a top surface, and the waterproof cover 11 and the waterproof cover 11 are arranged in the outer tub 1. Prevents insulation deterioration due to washing water during normal use, does not lead to a fire, and because the waterproof cover 11 and the waterproof cover lid 12 are made of flame-retardant resin and made of a metal cover, washing of an electric washing machine, Noise from vibration during dehydration can be prevented, and the noise caused by hitting metal (waterproof cover 11 and cover 12), metal and resin (power transformer 10) can be eliminated, and noise can be reduced.

[0014]

[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.

In addition, since the waterproof cover 11 and the waterproof cover lid 12 are made of a flame-retardant resin and are provided in the outer tub 1, insulation deterioration due to washing water during normal use is prevented, and a fire is prevented. It is possible to reduce the noise.
