DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention 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 configured as shown in FIG. Hereinafter, the configuration will be described.

[0003] As shown in the figure, a washing tank 1 includes a tableware basket 2.
And a washing pump 4 for supplying washing water to a washing nozzle 3 arranged below the tableware basket 2. A filter 5 for collecting residual vegetables (contaminants adhering to tableware and the like is referred to as residual vegetables) is provided below the washing tank 1.

In the dishwasher configured as described above, a detergent is put into the washing tank 1 and washing water at the bottom of the washing tank 1 is jetted from the washing nozzle 3 through the filter 5 by the washing pump 4. Garbage on tableware is washed off. The washing water containing the residual vegetables is filtered by the filter 5, circulated to the washing pump 4, and is repeatedly injected from the washing nozzle 3.

[0005]

Generally, the washing tub of a dishwasher is formed entirely of metal such as stainless steel, or the entire washing tub is formed of resin. By forming a washing tank with stainless steel,
Since there is no contamination, odor, or the like due to the residual vegetables in the cleaning tank or the cleaning water containing the detergent, the cleanliness can always be maintained.

However, when a cleaning tank is formed of stainless steel, welding is necessary to form a single box with a plurality of components, and the cost of parts is high and the degree of freedom in molding is low. It is necessary to configure the electrical components, the support of the piping, and the like with separate components, and there is a problem that the entire product is increased due to the components housed therein.

On the other hand, in the case of a cleaning tank made of resin, parts can be formed relatively inexpensively, and at the same time, electrical parts such as a pump and supporting parts for piping and the like are integrally formed to reduce the number of parts. Since it is possible to simplify the configuration of the entire product, for example, to reduce the size, and to make the entire product compact, cost merit is large and space can be saved.

[0008] However, unlike stainless steel, there is a possibility that contamination, smell, etc. may be attached, and there is a problem that the appearance is inferior in cleanliness.

The present invention solves the above-mentioned problems, and simplifies the overall structure of a product by using a resin at the bottom of a washing tank while keeping the cleanliness of stainless steel, making the entire product compact and inexpensive. It is intended to be.

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a washing tank for accommodating tableware and a resin bottom component, and a cleaning tank portion above the bottom component.
The cleaning tank body that composes the body is made of metal
There is .

Thus, while maintaining the cleanliness of the stainless steel, the overall structure of the product can be simplified by using the resin at the bottom of the washing tank, and the whole product can be made compact and inexpensive.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention according to claim 1 of the present invention is directed to a washing tank for accommodating tableware and washing water in the washing tank.
Pump for circulating water and washing from the washing pump
A washing nozzle for injecting water, wherein the washing tank is
All the components and the washing tank part above the bottom component
A cleaning tank main body constituting the body, wherein the bottom component
Is made of resin, and the other members are made of metal.While maintaining the cleanliness of stainless steel, the overall structure of the product is simplified by using resin at the bottom of the washing tank, making the entire product compact. Can be made cheaper.

According to a second aspect of the present invention, in the first aspect of the present invention, the bottom component has an upwardly rising portion integrally formed on a peripheral edge thereof, and is provided inside the rising portion. A receiving portion is formed, and the cleaning tank main body is formed with a substantially U-shaped portion bent outward at the lower end thereof, and the substantially U-shaped portion is inserted into the receiving portion from above, and the rising portion is formed. On the inner surface of the portion, an engaging portion that engages with the substantially U-shaped portion with its own elasticity is formed, and a cleaning tank is formed by a resin bottom component member and a metal cleaning tank body. When configuring, there is no need for welding, screw fastening, and the like, so that an easy-to-manufacture and inexpensive cleaning tank can be obtained.

[0014]

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) As shown in FIG.
Is a table for storing and washing the dishes 7, a resin bottom component 8 constituting the bottom of the cleaning tank 6, and a metal cleaning tank such as stainless steel provided on the bottom component 8. It comprises the main body 9. The cleaning tank 6 has an opening in front of a metal cleaning tank main body 9, and this opening is opened and closed by a door 10, and a cleaning nozzle 11 for spraying cleaning water to a resin bottom component 8 is rotated. Arranged freely.
A dish basket 12 for accommodating the dishes 7 is arranged in the washing tank 6.

The bottom component member 8 made of resin includes a bearing 13 that supports the cleaning nozzle 11 inside the cleaning tank 6, a cleaning water circulation path 14 that supplies cleaning water to the bearing 13, and a cleaning tank 6. The water supply path 15 for supplying the cleaning water and the like are integrally formed. In addition, electrical components such as a cleaning pump 16 and a water supply valve 17 are provided at the lower portion on the outside and support these components.

The operation of the cleaning tank body 9 described above will be described. The cleaning tank main body 9 is made of stainless steel so that the user can easily see the side wall of the cleaning tank body 9 during use. On the other hand, since the bottom surface component member 8 made of resin constituting the bottom of the cleaning tank 6 integrally forms the water supply path 15, the cleaning water circulation path 14, and the like, the number of parts can be reduced, and the bottom part can be reduced. The component 8 can support electrical components such as the cleaning pump 16.

Therefore, the cleaning tank body 9 made of metal can keep the cleanliness of stainless steel, simplify the whole structure of the product by the bottom component member 8 made of resin, and can make the whole product compact and inexpensive. Can be

(Embodiment 2) As shown in FIG. 2, a resin bottom component 8a is provided with a cleaning tank main body 9a made of a metal such as stainless steel provided on the bottom component 8a. Make up. The bottom component 8a made of resin has a rising portion 18 integrally formed on the periphery thereof and a receiving portion 19 formed inside the rising portion 18.

On the other hand, the metal cleaning tank body 9a has a substantially U-shaped portion 20 bent outward at the lower end thereof, and this substantially U-shaped portion 20 is inserted into the receiving portion 19 from above.

0 has an engaging portion 21 that engages with its own elasticity. Other configurations are the same as those in the first embodiment.

The operation of the cleaning tank will be described. The cleaning tank is formed by inserting a metal cleaning tank main body 9a from above a resin-made bottom component 8a so that the substantially U-shaped part 20 has its own. It is engaged with the engaging portion 21 by elasticity, and the vertical direction of removal is regulated. The resin bottom component 8a and the metal cleaning tank main body 9a are joined together to form a cleaning tank. be able to.

The elasticity of the substantially U-shaped portion 20 is determined by resin and
Since the difference in thermal contraction in the horizontal direction due to a different linear expansion coefficient from that of the metal is absorbed, leakage of the washing water from the joint can be prevented. Therefore, there is no need for welding, screw fastening, and the like, and an easy-to-manufacture and inexpensive cleaning tank can be configured.
