Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a dishwasher for washing dishes and the like by spraying washing water.

[0002]

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

As shown in FIG. 3, the door body 1 is openably and closably attached to the lower portion of the dishwasher main body 3 by the door support member 2 so as to cover the front opening of the dishwasher main body 3.
A handle portion 4 that is gripped when opening and closing the door body 1 and a lock means 6 that is released by a switch 5 are provided on the upper portion so that the door body 1 can be fixed in a closed state. The dishwasher main body 3 has a washing tank 7 provided therein, and the washing tank 7 has a dish basket 8 arranged therein. Reference numeral 9 is a cleaning pump, and 10 is a cleaning nozzle.

The operation of the above configuration will be described.
The user releases the lock means 6 with the switch 5, then holds the handle portion 4 to open the door body 1, and removes the dirty dishes in the dish basket 8 installed in the washing tank 7 in the dishwasher body 3. set.

Next, when the door 1 is closed and the lock means 6 is operated to start the operation, the heater (not shown) disposed at the bottom of the cleaning tank 7 heats the cleaning water,
The cleaning water is pumped to the cleaning nozzle 10 by the cleaning pump 9,
A washing process is performed in which the dishes are sprayed to remove stains from the dishes. After that, after rinsing the tableware, a drying process of drying is performed and the operation ends.

Another dishwasher is disclosed in Japanese Patent Laid-Open No. 50-
Some are described in Japanese Patent No. 26356. As shown in FIG. 4, two door bodies 1 provided in the dishwasher main body 11
Reference numerals 2 and 13 have a configuration in which the openings of the cleaning tank 16 are opened and closed by respectively rotating in the vertical direction via the door supporting members 14 and 15.
Interlocking means 17, 18 and connecting member 1 interlocking them
They are connected by 9, 20, and 21. Therefore, if the lower door body 13 is opened, the upper door body 12 is also opened at the same time,
By opening and closing individual doors at the same time, the convenience of opening and closing the doors is improved.

[0007]

With such a conventional structure, as shown in FIG. 3, the operation of the locking means 6 and the handle portion 4 for opening the door body 1 are usually provided separately. When the body 1 is opened, it is necessary to release the lock means 6 with the switch 5 and re-grip the handle portion 4. Further, since the door body 1 is biased in the closing direction, the handle portion 4 has to be grasped and opened until the end of opening, which is troublesome and inconvenient.

Further, in the configuration of FIG. 4, the door body is divided into two door bodies 12 and 13, and the amount of protrusion from the dishwasher main body 11 to the front when the door body is opened is reduced to reduce the dishwasher. Improves ease of installation when installing, and also multiple doors 1
2 and 13 are rotatably connected by an interlocking means 17 to improve the convenience of opening and closing the door body.
The opening of No. 3 had the same annoyance as the one-door.

In order to realize this conventional structure, a dishwasher is produced. At the time of assembly, a plurality of door bodies 12, 13, door support members 14, 15, interlocking means 17, 1,
It is necessary to connect and assemble many parts such as 8, and the connecting members 19, 20, and 21, respectively, and the assembling order is also complicated. Furthermore, it is necessary to store these components in the dishwasher main body 11, which causes a problem that the width dimension of the cleaning tank 16 is reduced and the dish capacity that can be accommodated is reduced.

The present invention is intended to solve the above problems, and an object of the present invention is to provide a dishwasher which realizes a door body that is convenient for opening and closing with a simple structure and a compact size.

[0011]

In order to achieve the above object, the present invention provides a washing tub in a dishwasher main body, and an opening provided in the washing tub is opened and closed by a plurality of doors. Is openably and closably supported by a plurality of door support members, and a plurality of door support members are pivotally supported by a base member so that the plurality of door support members are interlocked by the interlocking means to automatically open the door body. Configured to be biased by an elastic body,
The base member, the door support member, and the interlocking device are arranged in this order on the outer wall of the cleaning tank.

Thus, the plurality of doors can be automatically opened by a simple operation, the plurality of doors can be opened and closed very easily, the trouble in use can be eliminated, and the cleaning tank It is only necessary to assemble the base member, the door support member, and the interlocking means on the outer wall in this order, and it is possible to assemble easily with a very simple configuration. Furthermore, the base member, the door support member, and the interlocking unit can be easily unitized, and this unit can be attached to the washing tank or the dishwasher body, and the assemblability can be further improved.

Further, in order to achieve the above object, a washing tank is provided in the dishwasher main body, an opening provided in the washing tank is opened and closed by a plurality of door bodies, and these door bodies are provided by a plurality of door supporting members. Is supported by the base member to pivotally support the plurality of door support members, and the plurality of door support members are interlocked by the interlocking means, and the door body is automatically urged to open. The elastic body has the other end connected to the interlocking means and is provided on substantially the same plane as the interlocking means.

Thus, since the elastic body and the interlocking means are provided on substantially the same surface, automatic opening of a plurality of convenient door bodies can be performed by a compact structure without reducing the width of the cleaning tank. Can be realized.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION The invention according to claim 1 of the present invention comprises a dishwasher body, a washing tank provided in the dishwasher body, and a plurality of opening / closing openings provided in the washing tank. A door body, a plurality of door support members that openably and closably support the door body, a base member that pivotally supports the plurality of door support members, and an interlocking unit that interlocks the plurality of door support members,
The door supporting member is provided with an elastic body urged to automatically open the door body, and an outer wall of the cleaning tank has a base member,
The door support member and the interlocking means are arranged in this order, and a plurality of door bodies can be automatically opened by a simple operation.
Opening and closing of multiple doors is extremely easy, eliminating the hassle during use, and the outer wall of the cleaning tank has a base member,
It is only necessary to assemble the door support member and the interlocking means in this order, and it is possible to assemble easily with a very simple structure. Furthermore, the base member, the door support member, and the interlocking unit can be easily unitized, and this unit can be attached to the washing tank or the dishwasher body, and the assemblability can be further improved.

The invention according to claim 2 is a dishwasher main body, a washing tub provided in the dishwasher main body, a plurality of doors for opening and closing an opening provided in the washing tub, and the door A plurality of door support members that support the plurality of door support members in an openable and closable manner, a base member that pivotally supports the plurality of door support members, an interlocking device that interlocks the plurality of door support members, and the door support member with the door. An elastic body urged to automatically open the body, the elastic body having the other end connected to the interlocking means and provided on substantially the same plane as the interlocking means, which is convenient for use. Good automatic opening of a plurality of doors can be made more compact and can be realized without reducing the width of the cleaning tank.
