[0004]

In such a conventional configuration, all of the electrical components used, such as the motor 6, the water supply valve 7, the drain valve 8, and the control device 9, are configured in accordance with overseas voltage specifications. Therefore, for each electrical component, it was necessary to study and develop the product pressure and winding specifications. Further, since the motor 6 and the control device 9 differ depending on the product, the voltage specifications (for example, 110V, 120V, 220V,
40V).

The present invention is directed to an electric washing machine in which all the electric components used are not configured to meet overseas voltage specifications, that is, an electric power washing machine provided with a power supply transformer of an input power supply. It is.

[0006]

In order to achieve the above object, the present invention provides a water receiving tank suspended in an outer tank, a washing and dewatering tank and a stirring blade rotatably disposed in the water receiving tank. When,
A deceleration mechanism for driving the stirring blade disposed outside the water receiving tank at the center of the water receiving tank; a motor for transmitting a driving force to the deceleration mechanism; a water supply valve for supplying water to the water receiving tank; A drain valve for draining washing water in the tub, a control device for controlling the motor, the water supply valve, and the drain valve; and a power transformer for input power to electrical components such as the motor, the water supply valve, the drain valve, and the control device. And a lead cover for inputting and outputting to the power transformer, a waterproof cover covering the power transformer, and a waterproof cover lid attached to the waterproof cover from below, wherein the waterproof cover and the waterproof cover The lid is made of flame-retardant resin, and the contact portion of the waterproof cover lid with the reed sen is provided in the outer tub with a comb shape.

[0007]

As described above, according to the present invention, the motor 6, the water supply valve 7,
It is not necessary to configure all the electrical components used such as the drain valve 8 and the control device 9 according to the overseas voltage specifications, and it is not necessary to examine and develop the product pressure and winding specifications for each electrical component. . Conventionally, the motor 6 and the control device 9
In each case, the voltage specifications (for example, 110 V, 120 V, 220 V)
V, 240 V), but by using a power supply transformer of the input power supply, the voltage correspondence of the motor 6 and the control device 9 becomes unnecessary.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. The same components as those in the conventional example are denoted by the same reference numerals, and description thereof is omitted.

As shown in FIGS. 1 and 2, a water receiving tank 2 suspended in an outer tank 1; a washing / dewatering tank 3 and a stirring blade 4 rotatably disposed in the water receiving tank 2; A deceleration mechanism 5 for driving the stirring blade 4 disposed outside the water receiving tank 2 at the center of the water receiving tank 2, a motor 6 for transmitting a driving force to the deceleration mechanism 5, and a water supply for supplying water to the water receiving tank 2. A valve 7, a drain valve 8 for draining washing water in the water receiving tub 2, and a motor 6
A control device 9 for controlling a water supply valve 7 and a drain valve 8; a power transformer 10 for input power to electric components such as the motor 6, the water supply valve 7, the drain valve 8 and the control device 9; 10 is covered with a box-shaped waterproof cover 11 having a top surface opened downward and a waterproof cover lid 12 attached to the waterproof cover 11 from below, and 13 is for input and output to the power transformer 10. The waterproof cover 11 and the waterproof cover lid 12 are formed of a flame-retardant resin, and the contact portion of the waterproof cover lid 12 with the reed sensor 13 is removed to form a comb 14 so as to form the outer tank. 1

Next, the operation of this embodiment will be described. It is not necessary to configure all the electrical 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. No need to consider and develop. Conventionally, since the motor 6 and the control device 9 are different depending on the product, the overseas voltage specification (for example, 11
0 V, 120 V, 220 V, 240 V), but by using the power supply transformer 10 of the input power supply, the voltage correspondence of the motor 6 and the control device 9 becomes unnecessary.

As described above, according to the present embodiment, by mounting the power supply transformer 10 of the input power supply, it is possible to cope with overseas voltage specifications, and the development schedule can be shortened.
Here, the power supply transformer 10 of the input power supply is used for 110 V, 120 V, 220 V,
It may correspond to 0V, or may correspond to low voltage and high voltage separately.

A waterproof cover 11 and a waterproof cover lid 12 are provided.
Is formed of a flame-retardant resin, the lower part of the waterproof cover 11 is opened to form a box shape having a top surface, and the contact portion of the waterproof cover lid 12 with the lead sensor 13 is comb-shaped and disposed in the outer tank 1. By doing so, insulation deterioration due to washing water during normal use is prevented, and fire is not caused. By making the shape of the comb 14, the water rebounding from the floor does not enter the inside of the waterproof cover 11. Here, by providing the corner R at the end of the comb 14 at the contact portion of the lead wire 13, the breakage of the lead wire 13 due to the dehydration vibration of the electric washing machine is also prevented.
Since the waterproof cover 11 and the waterproof cover lid 12 are formed of a flame-retardant resin and are formed of a metal cover, noise caused by vibrations during washing and dehydration of the electric washing machine can be prevented, and the metal (the waterproof cover 11 and the waterproof It is possible to eliminate the contact noise between the cover lid 12) and the metal and the resin (the power supply transformer 10), thereby reducing the noise.

[0013]

[Effect of the Invention] As is apparent from the above description of the embodiment, in the present invention, it is necessary to configure all the electric components used, such as the motor, the water supply valve, the drain valve, and the control device, in accordance with the overseas voltage specifications. There is no need to study and develop the product pressure and winding specifications for each electrical component. Conventionally, since motors and control devices differ depending on products, overseas voltage specifications (for example, 110
V, 120 V, 220 V, and 240 V), but by using the power transformer of the input power supply of the present invention, the voltage correspondence of the motor and the control device becomes unnecessary. In addition, the waterproof cover and the waterproof cover lid are formed of a flame-retardant resin, and the contact portion of the waterproof cover lid with the lead sens is removed, and the outer cover is formed in a comb shape so that the washing water during normal use is provided. Prevents insulation deterioration due to
Low noise can be achieved.
