Description

Detailed Description of the Invention [Industrial Application Field] The present invention relates to a tableware washer that sprays washing water onto tableware stored in a washing tank to wash the tableware. This invention relates to a tableware washer that can easily and reliably remove leftover food.

[Prior Art] Conventionally, dishes are washed by rotating a nozzle body using a washing water supply device such as a circulation pump, and spraying washing water onto the dishes in a washing tank from an injection hole provided in the nozzle body. Washing machines are well known. An example thereof will be explained with reference to FIG.

In FIG. 2, (1) is a washing tank in which a basket (3) containing tableware (2) is accommodated. Also, the cleaning tank (1)
Inside is a nozzle body (5) that rotates by hydraulic power sent by a circulation pump (4), and this nozzle body! Cleaning water flows into the basket (3) from the plurality of injection holes (6) provided here.
), and the tableware (2) is washed. The cleaning water used for this cleaning is temporarily stored at the bottom of the cleaning tank (1) by a water supply device (not shown), and is heated by a heating means (not shown) such as a heater until it enters the chamber (7). Leftover filter (8) installed inside, hose (
9) to the circulation pump (4), and returns to the nozzle body (4) again.
5) 1ζ is sent.

After washing the tableware (2) with washing water for a certain period of time in this way, the circulation pump (4) is stopped and the drainage pump (
11) to discharge the wash water from the drain pipe (10). Next, new wash water is supplied again to drive the circulation pump (4), rinsing is performed, and the wash water is discharged again. Finally, energize or clean the heater (not shown).
! Dry tableware (2) by blowing hot air into (1). It may be rinsed with hot water before drying.

[Problem 8 to be solved by the invention] The conventional tableware washer is configured as described above.
Since the washing water that has passed through the filter (8) containing leftover food is jetted out to rinse the tableware (2), the eluted bones of leftover food (for example, rice grains) are removed from the tableware (2). The filter (8
), and therefore it is troublesome to discard the leftover food accumulated in the filter (8).

The present invention was made to solve the above problems, and an object of the present invention is to provide a dishwasher that can easily and reliably remove leftovers and rinse dishes beautifully.

[Means for Solving the Problems] A tableware washer according to the present invention has a wash water inflow path having a concave drainage chamber connected to a drain pump at the bottom, and an opening in the upper part communicating with the inflow path. and a chamber in which a first filter is disposed between the outlet passage leading to the circulation pump, a lid plate at the opening, the first filter, and a second filter, and the chamber is detachably fitted into the drainage chamber. This is connected to a leftover food trap.

[Operation] During washing, the leftover food contained in the washing water is blocked by the first filter, and only the washing water is circulated. When the drain pump is activated after washing, the wash water containing small debris is discharged through the drain channel, and relatively large debris remains in the debris catcher.

By lifting the lid plate, the first filter and the leftover food trap can be taken out together, so that the leftover food in the residual food trap can be easily discarded.

[Embodiments of the Invention] FIG. 1 is an enlarged sectional view of essential parts of an embodiment of the present invention, and the present invention will be described below with reference to FIG. 2. In the figure, (21) is the bottom plate of the cleaning tank (1), and a chamber (22) is integrally formed at the bottom. It is diagonally partitioned into an outflow path (23) to the circulation pump (4) and an inflow path (24) for washing water.

(2B) is a connection part that connects the outflow channel (23) to the circulation pump with a hose (9), and (27) is a concave drainage chamber provided at the bottom of the inflow channel (24), with a drainage pipe (not shown). (2B). (2
9) is a recessed food waste trap that is removably fitted into the drainage chamber (27), and a second filter (30) is provided at the bottom. Note that the second filter (30)
It is preferable that the mesh be coarser than that of the 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 path (23), and (33) is the opening (32).
The lid plate (34) is a knob. In addition, there is a leftover food trap (
29) is attached to the first filter (25), and the first filter (25) is attached to the cover plate (33) with screws, etc., and the cover plate (33) is attached upward from inside the cleaning tank (1). By pulling it up, these can be taken out as one piece.

Next, the present invention will be explained in detail. When washing the basket (3) containing tableware (2) in the washing tank (1), first supply washing water into the washing tank (1), and then pour the washing water into the washing tank (1). and in the chamber (22). Next, when cleaning is started, the circulation pump (4) is activated to circulate the cleaning water and spray the cleaning water from the injection hole (6) of the nozzle body (5) to clean the tableware (2). . Washing water containing leftover food (35) that has flowed down from the tableware (2) during washing is drawn by the circulation pump (4), guided from the passage (31) to the inlet passage (24), and passed through the first filter ( 25), outflow tract (
23).

At this time, the leftover food (35) contained in the wash water is blocked by the first filter (25) and does not flow into the outflow path (23), and only the wash water is circulated. On the other hand, relatively small leftovers (
35) flows out to the discharge vibrator through the second filter (30), and relatively large leftovers (35a) pass through the second filter (30) and pass through the second filter (30).
9) remain within.

When cleaning is completed, the circulation pump (4) is stopped and the drainage pump is activated. This allows the cleaning tank (1) and chamber (22
) is discharged to the outside from the drain pipe. Of the leftovers contained in the wash water, relatively small ones are discharged together with the wash water, and relatively large ones remain in the leftover catcher (29).

When draining is finished, pull up the cover plate (33) as necessary and remove the first filter (2) that is integrally attached to it.
5) and the leftover food catcher (29) is pulled up and taken out to the outside, and the leftover food (35a) accumulated in the leftover food catcher (29) is thrown away. Then, supply fresh cleaning water again and perform rinsing.

In the above description, an example was given in which the present invention is applied to a washing machine that washes tableware by jetting out washing water from an injection hole provided in a nozzle body that rotates using hydraulic power sent by a circulation pump. However, the present invention can also be applied to other types of dishwashers, such as those that wash dishes by moving a nozzle body having a spray hole horizontally to eject washing water. can do.

[Effects of the Invention] As is clear from the above description, the present invention provides a first filter that hardly allows leftovers to pass between the inflow path of the chamber and the outflow path to the circulation pump, and A waste catcher with a second filter, which allows small waste to flow out and large waste to remain, is removably fitted into the drainage chamber provided at the bottom, so that the amount of waste eluted during rinsing is reduced. This has great practical effects, as there is no risk of it re-adhering to tableware, and the leftover food trap can be easily taken out and the leftovers collected therein can be thrown away.
