DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dishwasher provided with a door for opening and closing an opening of a washing tank.

[0002]

2. Description of the Related Art Conventionally, this type of dishwasher has been configured as shown in FIG. Hereinafter, the configuration will be described.

As shown in the figure, a dishwasher main body 1 has a washing tank 2 provided therein, and is placed and supported by an underframe 3.
An openable and closable door 4 is provided on the front surface, and a body 5 is provided below the door. On the back surface of the door 4, a back plate 6 having a seal portion with the cleaning tank 2 is provided, and inside the door 4, electric components 7 for controlling equipment are arranged.

A switch 8 for switching the operation of the dishwasher is provided on the electrical parts 7 for controlling the equipment so that the switch can be operated from the front of the equipment. This changeover switch 8
In order to improve the operability, it is arranged above the door 4, and the electric components 7 for controlling the equipment are also arranged above the door 4 at the same time.
Further, the electrical parts 7 for controlling the equipment are provided with a large number of connection parts 9 and are connected to load parts such as a pump 10 by wirings 11.

Further, the body 5 is fixed to the dishwasher main body 1 or the underframe 2 and requires piping when installed in a kitchen or the like, so that it can be easily removed.

[0006]

In such a conventional configuration, the electric parts 7 for controlling the equipment are provided with electric parts for controlling all the load parts such as the pump 10 and the connecting part 9. Because it is installed, it becomes large and heavy. Further, since the electrical components 7 for controlling the device are located above the door 4, the moment applied when the door 4 is opened and closed increases, and the feeling of opening and closing the door 4 deteriorates.

Further, since the number of lead wires constituting the wirings 11 is large, and among them, those having a large current value use lead wires having a large wire diameter. The bent portion of the wiring 11 below the door 4 becomes hard. Therefore, it is necessary to take some measures so that the opening / closing operation feeling of the door 4 does not deteriorate.

Further, since the back plate 6 provided on the door 4 forms a seal portion, the back plate 6 has a structure that cannot be easily removed, and is used for maintenance and maintenance while the dishwasher is installed in a kitchen or the like.
When performing an inspection, there is a problem that it takes time and effort to remove the electric components 7 for controlling the device.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and reduces the weight of the door and reduces the number of lead wires constituting the wiring inside the door, thereby improving the opening / closing operation feeling of the door.
An object of the present invention is to make it easier to take out electrical components for controlling a device necessary for inspection and to easily perform maintenance and inspection work.

[0010]

According to the present invention, in order to achieve the above object, a dishwasher body provided with a door for opening and closing an opening of a washing tank is placed on and supported by a frame, and the frame is forwardly mounted on the frame. A storage box is provided so as to be freely drawn out, and electrical components for controlling equipment are stored in the storage box.

As a result, the door opening / closing operation feeling can be improved by reducing the weight of the door and reducing the number of lead wires constituting the wiring inside the door. Electrical parts can be easily taken out, and maintenance and inspection work can be easily performed.

[0012]
