Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a tableware washing apparatus, and more particularly, to a residue processing means thereof.

[Conventional technology]

Dishwashers can be roughly divided into shower type and soaking type. In the shower type, for example, a nozzle sprays cleaning water onto tableware to wash away dirt adhering to it. On the other hand, in the soaking method, dishes are soaked in washing water for a predetermined period of time to remove some dirt, and then, like the shower method, the dishes are sprayed with washing water to be washed.

[Problem to be solved by the invention]

In any case, it was washed away. To collect the residue,
A residue collection means is provided near the drain or in the washing water circulation path.

Conventionally, most of the residue collection means consist of a mesh basket, but when it is full, the basket must be taken out and thrown away, which is considered one of the troublesome tasks for housewives. Furthermore, if the residue remains stored inside the machine, its volume is limited, so it is necessary to remove the residue each time before washing dishes. In particular, if the residue is left in the container, it will rot and cause sanitary problems.

The present invention was made in view of the above-mentioned conventional circumstances, and an object thereof is to provide a cleaning device equipped with a residue processing means that can automatically discharge the washed residue to the outside of the machine.

[Means to solve the problem]

In order to achieve the above object, the present invention provides tableware comprising a washing tank for storing tableware to be washed, and a washing water supply means for supplying washing water for the tableware into the washing tank. The cleaning device is characterized in that a collection container is provided at the bottom of the cleaning tank to collect the residue by the flow of cleaning water, and the collection container is provided with a residue processing means for discharging the residue to the outside of the machine. There is.

In this case, the residue processing means includes a conveying pipe that rises upward at a predetermined angle from the bottom of the collection container, has a residue intake port at its lower end, and has a residue discharge port formed at its upper end; a screw inserted into the pipe and a drive means for rotating the screw;
and a drain pipe for discharging the wash water in the collection container.

[For production]

The residue washed away by the washing water flows into the collection container together with the washing water. Then, the waste is preferably drained by a screw of the residue processing means and dumped into, for example, a garbage storage bag outside the machine, without requiring any manual labor.

〔Example〕

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

This cleaning device includes a housing 2 having a cleaning tank 1 inside. In this embodiment, the housing 2 is installed beside the sink 3. Inside the washing tank 1, for example, two shelves 4 and 5 are provided in upper and lower stages for placing tableware to be washed. There are 3-4. In this case, the upper shelf 4 is intended to hold dishes such as dishes, and the lower shelf 5 is intended to hold heavily soiled dishes, relatively deep pots, bowls, or bowls.

A first nozzle 6 is provided on the side of the upper shelf 4 to spray washing water from the side onto the tableware placed there. Further, a second nozzle 7 is arranged on the lower shelf 5 to spray cleaning water from below to above. In this example, two nozzles 7 are arranged on the left and right. In this embodiment, a water supply pipe 26 for supplying, for example, tap water (washing water) into the washing tank l is provided at the top of the washing tank l.

On the bottom side of the cleaning tank 1, more specifically on the sink 3 side,
A collecting table 8 is connected to collect the washing water' and the residue washed away by the washing water. An eaves-shaped partition plate 9 is provided on the top of the collection container 8 to partition the collection container 8 and the inside of the cleaning tank 1 and to prevent washing water and residue from directly flowing into the collection container 8. ing. That is, this partition plate 9 forms a funnel-shaped drainage part together with the bottom wall 1a of the cleaning tank 1, and the cleaning water and residue are drained from the bottom wall 1a.
It is inclined so that it flows into the collection container 8 through the pipe.

In this embodiment, below the bottom wall 1a of the cleaning tank 1, a magnetic particulate collecting means 11 for collecting magnetic particulates 10 made of a magnetic material is provided. The collecting means 11 is composed of, for example, a belt 13 stretched between a pair of rollers 12a, 12b, and a large number of permanent magnets 14 provided at predetermined intervals.

Furthermore, a pump means 15 is provided at the lower part of the cleaning tank 1 for supplying cleaning water to the first and second nozzles 6 and 7. This pump means 15 includes a first pump 15a that supplies cleaning water to the first nozzle 6 through a pipe (not shown), and a second pump 15b that is connected to the second nozzle 7 through a discharge pipe 16a. It is equipped with In addition,
This second pump 15b has a magnetic particle recovery port 1 opened at the bottom of the cleaning tank 1 through its suction pipe 16b.
7 is connected.

The collection container 8 includes a draining basket 27 and a residue processing means 2.
0 is provided. The draining basket 27 may be of a known type, but the residue processing means 20 rises upward from the bottom of the collection container 8 at a predetermined angle, has a residue intake port 21a at its lower end, and has a residue discharge port at its upper end. It has a conveyance pipe 21 in which an outlet 2lb is formed, and a screw 22 inserted into the conveyance pipe 2l.

By rotating the same screw 22 with a motor (not shown), the residue in the recovery container 8 is taken in from the inlet 21a, conveyed to the residue outlet 2lb while preferably draining, and the residue is placed directly below the outlet 2lb. Dump it into the set garbage storage bag 23 shown in the imaginary line. In this embodiment, the drain pipe 3a of the sink 3 is also communicated with the collection container 8, so that the dishwashing device and the sink 3 share the residue processing means 20. Further, a drain pipe 24 is connected to the bottom of the collection container 8 . Although not shown in detail, the drain pipe 24 is equipped with a trap for storing a predetermined amount of cleaning water in the collection container 8, that is, for keeping the liquid level at least above the residue intake port 21a, This prevents bad odor from flowing back from the garbage storage bag 23 side.

Note that 24a is a drainage extension pipe that guides the washing wastewater that has overflowed the trap to the outside of the machine.

A two-way switching valve 25 is provided at a predetermined portion of the drain pipe 24 to switch the drain pipe 24 to either the drain extension pipe 24a side or the pump means 15. In this case, although not shown in detail, the pipe 29 leading from the two-way switching valve 25 to the pump means 15 side is branched in the middle, and one of the pipes joins the suction pipe 16b to form the second pump 15b.
It is connected to the. Also, the other one is the lth bomb 15

Cleaning water not containing magnetic particulate matter 10 is supplied from a to the first nozzle 6, and cleaning water containing magnetic particulate matter 10 is supplied to the second nozzle 7 from the second pump 15b. Therefore, the magnetic granules 10 are sprayed exclusively onto the tableware placed on the lower shelf 5, thereby cleaning off any residue such as rice grains adhering to the tableware. The magnetic granules 10 after washing are collected by a magnetic granule collecting means 1
1, and again from the second pump 15b.
is supplied to the nozzle 7 of. On the other hand, the washed residue flows into the collection container 8, and the residue processing means 20 flows from the bottom thereof.
The waste is preferably drained with a screw 22 and dumped into a waste storage bag 23. In addition, leftover food from the sink 3 is similarly dumped from the collection container 8 into the garbage storage bag 23 by the screw 22 of the residue processing means 20.

After cleaning, to drain the cleaning water, switch the two-way switching valve 25 to the drain extension pipe 24a side. As a result, the cleaning water is drained, but due to the presence of the trap, enough cleaning water remains in the collection container 8 to submerge the residue intake port 21a, preventing backflow of bad odor from the garbage storage bag 23 side. be done.

In the embodiment described above, the magnetic particles 10 are supplied only to the second nozzle 7, but depending on the situation, the magnetic particles 10 may also be supplied to the first nozzle 6. On the other hand, although the above embodiments relate to a so-called shower type, the present invention is also applicable to a soaking type.
