Description

[Detailed Description of the Invention] (a) Field of industrial application The present invention relates to a dishwasher in which a pump filter is arranged at a suction port portion of a washing pump formed in a lower portion of a side plate of a washing tank. Is.

(B) Conventional technology As a conventional technology, for example, in Japanese Utility Model Publication No. 54-4377, a washing chamber is provided in the upper portion of the main body to wash the transferred dishes by spraying washing water by a washing device, and the upper portion is provided at the lower portion. In a dishwasher provided with a tank chamber for storing the cleaning water covered with a strainer, both side ends adjacent to each other are attached to one corner of the tank chamber substantially parallel to the bottom surface of the chamber, and other side ends adjacent to each other A top plate having rising pieces, and a partition plate detachably engaged with each of the rising pieces and having a large number of holes formed in the lower portion thereof,
Disclosed is a dishwasher in which a suction chamber is formed from an inner wall of a tank chamber and a suction port of a pipe faces the suction chamber.

(C) Problems to be solved by the invention Such a conventional dishwasher has a filter device configured by connecting a plurality of plates such as a top plate and a partition plate. It had to be done at the bottom of the tank, i.e. in the dirty wash water.

Here, generally, this type of dishwasher is placed in a store that handles food such as a restaurant, and a filter is attached and detached by a clerk who handles the food. Especially when the filter is removed, the filter is washed afterwards, so you can clean your hands, but when you put it on, you put your hands in the dirty water (washing water) in the wash tank. It was a hygienic problem.

The present invention has been made in view of these problems, and provides a dishwasher for easily attaching / detaching a filter, and particularly for attaching the filter without putting hands in washing water. To do.

(D) Means for Solving the Problems In order to achieve the above-mentioned object, the present invention is equipped with a removable filter on the upper surface, and a cleaning tank having a suction port formed on the lower portion of a side plate, and the cleaning tank. The main body,
A door body that opens and closes a washing chamber formed above the main body, and a washing pump that circulates the washing water in the washing tank through a washing nozzle arranged in the washing chamber and is connected to the suction port. A dishwasher comprising: a pump filter having a frame body having a handle fixed upper surface and an inclined surface; a filter surface surrounded by the frame body and having a number of small holes formed therein; and a side plate of the cleaning tank. And a filter rail which is fixed to the lower part of the side plate and is inclined in the direction of the suction port of the cleaning pump. The filter rail has a sliding surface on which the inclined surface of the frame slides. A dishwasher having a guide surface for guiding the pump filter to a predetermined position facing the suction port.

(E) Operation According to the present invention, the pump filter is guided by the guide surface of the filter rail by holding the handle on the inclined surface of the frame on the sliding surface of the filter rail and then releasing the handle. Slide into position.

(F) Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 5. (1) is a rectangular washer body with an open top surface, and above the body (1) is formed a washing chamber (3) whose front and both sides are opened by a door body (2) that can be moved up and down. Has been done. A washing nozzle (4) and a rinsing nozzle (5) are provided above and below the washing chamber (3), respectively, and are provided in the main body opening portion slightly above the lower washing nozzle (4) and the lower rinsing nozzle (5). Is provided with a rack rail (8) on which a rack (7) accommodating an article to be cleaned (6) is placed. In addition, inside the main body (1) below the cleaning chamber (3),
A cleaning tank (10) having a removable filter (9) arranged on the upper surface is equipped, and the cleaning water stored therein is circulated to the upper and lower cleaning nozzles (4) by a cleaning pump (11). (12) is a booster for rinsing, and the rinsing water heated and heated here is pumped by the rinsing pump (13) to the upper and lower rinsing nozzles (5).

Thus, the cleaning pump (11) connects the suction pipe (11A) to the suction port (14) formed in the lower part of the side plate (10B) near the rear plate (10A) of the cleaning tank (10). , The suction port (14) is equipped with a pump filter (15) detachably. This pump filter (15) has an upper surface portion (16A), a front surface portion (16B), as shown in FIG. 4 and FIG.
A frame body (16) having a rear surface portion (16C), a bottom surface portion (16D), and an inclined surface portion (16E) between the front surface portion (16B) and the bottom surface portion (16D).
And the handle (1) fixed to the upper surface (16A) of the frame (16)
7) and a large number of small holes (1
8) and the filter surface (19) which is perforated.

Further, in order to attach the pump filter (15) at a predetermined position covering the suction port (14), the side plate (10B) of the cleaning tank (10) has a filter rail which is inclined downward toward the suction port (14). (20) is fixed. The filter rail (20) has a sliding surface (20A) slightly wider than the width of the frame body (16) and a side plate (10B) formed by bending the outer side upward.
Has a guide surface (20B) facing each other, and the rear surface plate (10A) has a guide surface (21A) which is substantially coplanar with the guide surface (20B) and this tip is bent outward obliquely. The guide rail (21) having the receiving surface (21B) is fixed.

In the above structure, when attaching the pump filter (15), hold the handle (17) and attach the inclined surface portion (16E) of the frame body (16) to the filter rail (20) as shown by the dotted line in FIG. When the handle (17) is placed on the sliding surface (20A) and released, the pump filter (15) is disengaged from the filter rail (20) due to the inclination of the sliding surface (20A) and the guide surface (20B). Without sliding, the frame (16) surrounds the suction port (14), and the filter surface (19) is guided to a predetermined position facing the suction port (14). Thus, in the pump filter (15), the bottom surface portion (16D) of the frame body (16) abuts on the bottom surface plate (10C) of the cleaning tank (10), and the inclined surface portion (16E) of the filter rail (20). It stops while riding on the sliding surface (20A), and in this state, the pump filter (15) falls and the filter rail (2
It is reliably prevented by the guide surface (20B) of (0) and the guide surface (21A) of the guide rail (21). Also,
When cleaning the pump filter (15), you can easily remove the pump filter (15) from the cleaning tank (10) by holding the handle (17) and pulling the pump filter (15) toward you. .

(G) Effect of the Invention As described above, the present invention holds the handle and puts the inclined surface of the frame on the sliding surface of the filter rail, and then simply releases the handle to tilt the sliding surface and guide the surface. By the action, the pump filter can be set to the lower position of the cleaning tank, and the pump filter can be easily removed from the cleaning tank by pulling up the handle.
The pump filter can be easily attached and detached.
