Description

Description: BACKGROUND OF THE INVENTION [0001] The present invention relates to a dishwasher for washing dishes by squirting washing water onto dishes stored in a washing tank. The present invention relates to a dishwasher capable of easily and reliably removing generated residual vegetables.

[Prior art] Conventionally, a tableware in which a nozzle body is rotated by using a cleaning water supply device such as a circulation pump, and cleaning water is sprayed to tableware in a cleaning tank from a spray hole provided in the nozzle body to wash the tableware. Washers are well known. An example will be described with reference to FIG.

In FIG. 2, (1) is a washing tank in which a basket (3) containing tableware (2) is stored. In the washing tank (1), there is provided a nozzle body (5) which is rotated by hydraulic power sent by a circulation pump (4). Is sprayed toward the basket (3), and the dishes (2) are washed. The washing water used for this washing is temporarily stored in the bottom of the washing tank (1) by a water supply device (not shown), and is heated by heating means (not shown) such as a heater.
The food is returned to the circulation pump (4) via the garbage filter (8) provided in the chamber (7) and the hose (9), and is sent to the nozzle body (5) again.

After the tableware (2) is thus washed with the washing water for a certain period of time, the circulation pump (4) is stopped, the drainage pump (11) is operated, and the washing water is discharged from the drainage pipe (10). Next, fresh washing water is supplied again, and the circulation pump (4) is driven to perform rinsing, and the washing water is discharged again. Finally, a heater (not shown) is energized or hot air is blown into the washing tank (1) to dry the dishes (2). Rinsing with hot water may be performed before drying.

[Problems to be Solved by the Invention] The conventional dishwashing machine is configured as described above, and the washing water that has passed through the filter (8) in which the garbage is accumulated is jetted to remove the dishware (2). Since the rinsing is performed, the eluted residue (for example, rice grains) adheres to the tableware (2) and cannot be completely finished, and the filter (8) is structurally taken out, and thus the filter is removed. There is a problem that it is troublesome to discard the residual vegetables accumulated in (8).

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a dishwasher capable of easily and surely removing residual vegetables and beautifully rinsing the dishes.

[Means for Solving the Problems] A dishwashing apparatus according to the present invention has an inflow passage provided with a concave drainage chamber below which communicates with a drainage pump, and an opening at an upper portion to communicate with the inflow passage. An outlet channel leading to the circulation pump, and a first channel between the inlet channel and the outlet channel.
A filter disposed therein, a lid plate detachably attached to the opening of the outflow channel, and a garbage catcher detachably fitted to the drainage chamber with the second filter, The first filter is installed so as to be divided obliquely at substantially the center of the chamber, and the garbage catcher is provided below the first filter and opposed to the first filter.

[Operation] During the washing, the garbage contained in the washing water is blocked by the first filter, and only the washing water is circulated. When the drainage pump is operated after the washing, the garbage attached to the first filter is removed by the water flow and transferred to the garbage catcher provided with the second filter, and the washing water containing the small garbage is removed. Water catcher,
The relatively large garbage discharged through the drainage channel remains in the garbage catcher.

After washing and drying the dishes, remove the garbage catcher and discard the garbage.

FIG. 1 is an enlarged sectional view of a main part of an embodiment of the present invention.
The present invention will be described with reference to the drawings. In the figure, reference numeral (21) denotes a bottom plate of the cleaning tank (1), and a chamber (22) is integrally formed at a lower portion, and the chamber (22) is formed by a first filter (25) at a substantially central portion. Partitioned diagonally,
It is divided into an outflow channel (23) to the circulation pump (4) and an inflow channel (24) for the washing water. (26) is a connecting part connecting the outflow channel (23) to the circulation pump by the hose (9), (27)
Is a concave drain chamber provided below the first filter (25) at the lower part of the inflow passage (24) and opposed to the first filter, and is a connecting portion connected to a drain pipe (not shown). (28). (29) is the drain chamber (2
A concave garbage catcher detachably fitted in 7), and a second filter (30) is provided at the bottom. It is desirable that the second filter (30) has a mesh larger than that of the first filter (25). (31) is a passage leading from the cleaning tank (1) to the chamber (22), (32) is an opening provided in the bottom plate (21) above the outflow passage (23), and (33) is an opening (32). (34) is a knob. The garbage catcher (29) is attached to the first filter (25), and the first filter (25) is attached to the cover plate (33) with screws or the like. By pulling the lid plate (33) upward, these can be integrally taken out.

Next, the operation of the present invention will be described. When the basket (3) containing the tableware (2) is stored in the washing tank (1) for washing, first, washing water is supplied into the washing tank (1), and the washing water is supplied to the washing tank (1). Pool in the lower part of the chamber and in the chamber (22). Then, when washing is started, the circulation pump (4) is operated to circulate the washing water, and the washing water is ejected from the injection hole (6) of the nozzle body (5) to wash the dishes (2). . Washing water containing garnish (35) that has flowed down from tableware (2) by washing
It is drawn by the circulation pump (4) and the inflow passage (2
It is led to 4) and circulates through the first filter (25) and the outlet channel (23).

At this time, the garnish (35) contained in the washing water is blocked by the first filter (25) and does not flow into the outflow path (23).
Only the wash water circulates. On the other hand, relatively small residual vegetables (35)
Flows through the second filter (30) to the discharge pipe,
The relatively large garbage (35a) remains in the garbage catcher (29).

When the washing is completed, the circulation pump (4) is stopped, and the drainage pump is operated. This enables the cleaning tank (1) and chamber (2
