2. Description of the Related Art Conventionally, school lunch centers and the like use a large amount of dishes, dishes, and the like for washing a large quantity of equipment such as a high-pressure spray or a washing tank equipped with the dishes and the like. There is known a device that sequentially passes through a detergent or washing water for washing.
A device that is used when a food processor cleans a large amount of food is a device that sequentially passes through a series of water tanks by a conveyor equipped with a reversing basket or the like for storing the food. In a kitchen such as a room, a washing apparatus having a sink as shown in FIG. 8 has been used.

[0003] The cleaning apparatus shown in FIG. 8 comprises a rectangular sink 102 having a square or rectangular open top surface, and a drain port 124 at an appropriate position on the bottom surface 108 of the sink 102, for example, in the center, and an inner wall surface. An overflow drain port 112 is provided at an appropriate height to maintain a constant water depth in the sink. A net or a wire is provided at the overflow drain port 112 to prevent the outflow of a cloth or food material. In addition, a tap faucet 134 is provided for introducing cleaning water or hot water into the sink 102, and a work table surface 127 is often arranged on a side portion of the sink 102 depending on the location.

In such a conventional cleaning device, the sink 1
02, while putting water in it, put detergent in it, put dishes and cooking utensils according to kind or the same kind together, wash by hand immersion stirring for an appropriate time, for example, about 10-60 minutes, Over a predetermined amount of water, overflow drain 112
Is discharged from In particular, the fried cut vegetables are often washed only with water for each type, and the insertion and removal of utensils and ingredients into and from the sink are performed manually.

[0005]

However, cleaning of oil and dirt adhering to the surface of dishes and utensils such as cups and trays usually requires a detergent and a large amount of washing water. However, when washing in a conventional sink (washing device), since the overflow drainage port 112 is small, if the amount of water to be supplied is large, the overflow drainage port 112 is immediately blocked. The overflow drain port 112 is blocked, so that the drain port 112 is narrowed, so that the sink 102 overflows and wets the floor surface. And in order to avoid such a situation, the water supply 135 from the faucet 134 had to be reduced.

However, as shown in FIGS.
The tap water whose supply is restricted is supplied into the sink 102 with a water supply of 135.
When the water is supplied as water, first, a ripple 125 of water is generated on the surface of the washing water in the sink 102, and the ripple 125 spreads to the outer periphery, but the water flow itself breaks the surface tension and the stirring force for vigorously stirring the surface of the washing water is not sufficient. The movement range 126 of the underwater water is small, and the flushing efficiency of fresh water required for flushing the inside of the sink is low. Therefore, the flushing water in the sink has a surface tension of 135 to supply water. Rather, the ripples 125, which have no momentum, tend to push the suspended matter in the surface tension film toward the outer corner direction.
Since the overflow outlet 112 is one place and the area of the drain outlet is small, the drainage flow rate enough to break the surface tension cannot be obtained,
Suspended matter and suspended bacteria often remain suspended on the surface. In addition, under the surface of water near each corner in the sink, there is no movement of water that only pushes up and drains water containing contaminants and various bacteria. Tended to occur.

Further, in washing dishes, utensils and foodstuffs, a bactericidal surfactant, a neutral detergent and sodium hypochlorite, which are permitted as food additives, are added and washed. Bad, poor short-term cleaning effect,
Therefore, re-adhesion by the contaminants remaining in the sink is caused. Therefore, when cleaning chemicals or surfactants are used, the washing of dishes and utensils is completed with incomplete surface conditions that have not been washed off, and food poisoning bacteria and contaminants that are not sufficiently cleaned may be removed. There was a concern that the attached vegetables would appear on the table. An important issue is the merging of cut vegetables, particularly the removal of microorganisms such as Salmonella, Vibrio parahaemolyticus, Staphylococcus aureus, and E. coli such as O-157, which is currently a problem.

In addition, a conventional sink (cleaning device)
Then, besides the above-mentioned problems, for example, a table surface 127 for cooking by placing an object on the sink side or placing a cutting board or the like.
In many cases, the surface of the table is a lift that easily contaminates and deposits contaminants. When the inventors of the present invention inspected the state of contamination, they found a positive result. Staphylococci were detected. The test area of the exposed part that was not immersed in water above the overflowing water surface on the inner wall surface of the sink was also positive, and coliform bacteria and S. aureus were detected. Both are surface conditions contaminated with coliform bacteria and Staphylococcus aureus.Even if washing dishes and utensils in a sink surrounding such a contaminated area, from the surface of the contaminated territory to the water tank Tableware and utensils that are gradually washed as contaminated water flows into contaminated water can become infected and contaminated. In addition, when the overflow drainage flow rate is slow, such as when a net or slit is installed to prevent cut vegetables or cloth from flowing into the drainage pipe from the overflow drainage during sterilization cleaning, the surface tension inside the sink is formed. The film cannot be broken easily, overflow water is drained below the surface film while maintaining the surface film, and the water surface in the water tank and the drainage pipe are directly connected without steps or traps. , Bacteria that grew inside the drain pipe, food poisoning bacteria that grew in the gap where nets and slits were attached to the overflow drainage using packing material, and backflow into the sink due to the small overflow flow rate. To contaminate.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to solve the above-mentioned problems of the prior art. Use an overflow-type sink (washing device) that will not contaminate the dishes, utensils, and foodstuffs in the sink being washed because the drainage port of the wastewater will be contaminated by bringing in food and related equipment. It is intended to provide.

[0010]

SUMMARY OF THE INVENTION In accordance with this object, a food or utensil cleaning apparatus according to the present invention permits overflow of washing water at the upper end of the peripheral wall of a sink having an open top having a peripheral wall and a bottom wall. A plurality of openings and a plurality of weirs for blocking the flow of washing water are provided, and a protection member is provided to cover the upper edge by making a round along the upper edge of the peripheral wall. A gutter-shaped water receiver which is provided around the circumference and has an open top surface for receiving washing water overflowing from the opening is provided.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to the drawings showing an embodiment. 1 to 3, reference numeral 1 denotes a cleaning device. The cleaning device 1 has a sink 2. The sink 2 is an open-top water tank having a front wall 3, a rear wall 4, a left side wall 5, and a right side wall 6 and a peripheral wall 7 and a bottom wall 8 closing a bottom surface of a space surrounded by the peripheral wall 7. Perimeter wall 7
V that allows overflow 33 of washing water at the upper end 11
A plurality of opening portions 12 in the shape of a letter and a plurality of trapezoidal weir portions 13 for preventing overflow 33 of washing water are provided. It is desirable to form openings 12 at the four corners 14 of the upper end 11 of the peripheral wall 7 of the sink 2.

A protection member 16 is attached so as to make a round along the upper edge 15 of the peripheral wall 7 and cover the upper edge 15. The protection member 16 is formed of a metal or resin pipe or rod, and is attached to the upper edge 15 of the peripheral wall 7 by welding. Alternatively, the protection member 16 may be formed by curling the upper edge 15 of the peripheral wall 7 so that the opening 12 is not closed. This protective member has a function of covering the sharp edge of the upper edge 15 of the peripheral wall 5 and preventing the finger from touching the edge. A water receiver 17 is attached around the outer surface of the peripheral wall 7. The water receiver 17 has a gutter shape with an open top surface, and receives the washing water overflowing from the opening 12 of the peripheral wall 7. As shown in FIG. 3, the bottom surface 18 of the water receiver 17 is inclined from a highest position 21 to a lowest position 22, and has a drain port 23 at the lowest position 22. An openable / closable drain port 24 is provided at the center of the bottom wall 8.

In the cleaning apparatus 1 constructed as described above, when cleaning foods and dishes, the foods and dishes are put into the sink 2 and tap water is supplied directly from the upper faucet 34 or through a hose or pipe. Washing with running water in the sink. The overflow water flows down from the opening 12, falls down, is stored in the water receiver 17, flows down the bottom surface 18 to the lowest position 22, and is drained from the drain outlet 23.

In this cleaning apparatus 1, cleaning of oil and dirt adhering to the surface of dishes and utensils such as cups and trays usually requires a detergent and a large amount of cleaning water. In the case of washing with water, since the opening 17 for overflow drainage is large, even when the amount of water to be supplied is large, as shown in FIG. The cut vegetables do not block the opening 17, and a good running water is formed in the sink, so that the washing is performed well. Further, since the water of the overflow 33 is stored in the water receiver 17, there is no possibility that the floor surface is wet.

As a result of the sufficient flow of water, as shown in FIGS. 5 and 6, when tap water is supplied into the sink 2, first, a ripple 25 of water is generated on the surface of the washing water in the sink 2. Then, the ripples 25 spread to the outer circumference, the water flow itself breaks the surface tension, and the stirring force for vigorously stirring the surface of the washing water is large, and the range of the movement 26 of the water below the water surface also becomes large, so that the inside of the water tank is cleaned. Improve the flushing efficiency of required fresh water. In addition, since a large number of openings 12 that allow overflow are provided and the drainage area is large, a sufficient drainage flow rate to break the surface tension can be obtained, and floating substances and floating bacteria can remain floating and mixed on the surface. Absent.

Conventionally, there is no movement of water around the corners inside the tank below the surface of the water, which merely pushes up and drains water containing contaminants and various bacteria. However, in the cleaning device of the present invention, if the upper part of the corner of the sink 2 is an opening 12 that allows overflow water, a contaminated dead water area where water does not move does not occur. .

Further, in washing dishes, utensils and foodstuffs, a bactericidal surfactant, a neutral detergent and sodium hypochlorite, which are permitted as food additives, are added for washing. The cleaning device has a high flushing efficiency, so the short-time cleaning effect is high, so that re-adhesion by contaminants remaining in the sink does not occur, and when using cleaning chemicals or surfactants, these can be cleaned. There is no need to worry about washing dishes and utensils while the surface condition is not incomplete and the vegetables with food poisoning bacteria and contaminants that have not been sufficiently washed may come out to the table.

In addition, in the sink (cleaning device),
For example, in many cases, a place is provided on the sink side to serve as a table surface 27 for cooking with a dish or a chopping board placed thereon, but the table surface 27 is likely to be contaminated and is likely to accumulate contaminants. However, since there is a water receiver 17 between the table surface 27 and the sink 2, tableware in which contaminants gradually flow as contaminated water into the water tank from the surface of the contaminated castle and are washed. Equipment will not be contaminated. Furthermore, in the cleaning device of the present invention, even when a net or a slit is attached to the drain port 23, the overflow drain flow velocity can be increased, and the water surface in the sink and the drain pipe are isolated, so that the inside of the drain pipe is The food poisoning bacteria which propagated in the gap where the bacteria, nets and slits propagated in the overflow drain port are attached to the overflow drainage using packing material do not flow back into the water tank of the sink 2 to contaminate the inside of the sink. The upper end surface of the weir is provided with a protection member made of a round bar, a square bar or a pipe, or a curl of the weir to protect workers' fingers,
Prevent the occurrence of finger injuries.

FIG. 7 shows a cleaning apparatus according to another embodiment of the present invention. In the cleaning apparatus shown in FIG.
8 and the bottom wall 8. In such a configuration, the rectified water 32 that has passed through the punching plate cleans kitchen utensils in the tub while eliminating dead water areas in the sink 2.

[0020]

As described above, the sink of the food utensil cleaning apparatus according to the present invention has a cleaning structure in which overflow drainage is performed while breaking surface tension, so that infection contamination in the tank cannot be achieved with the conventional sink. It is possible to prevent kitchenware and kitchen utensils and ingredients for a short period of time, and it has a safety mechanism that does not hurt cooking workers. It has a sink for overflow water pools, external contaminants and various food poisoning bacteria. A sink with an inclined groove structure that does not cause internal contamination can always provide a clean environment in and around the sink.
