DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dishwasher used in the restaurant industry such as a restaurant, a bottle washer for washing beer bottles and liquor bottles, and a plastic container washing machine used for washing plastic containers. The present invention relates to a supply device for supplying a solid cleaning agent to the like.

[0002]

2. Description of the Related Art In recent years,
In the field of the food service industry and the food industry, the shortage of manpower has become serious, and studies have been made to minimize manpower and perform work safely and efficiently. In addition, today, attention is paid to environmental pollution due to industrial waste and the like, and there is a tendency to use equipment and products that do not emit pollution.

[0003] As a means for solving the labor shortage, automatic dishwashers have rapidly spread in the food service industry and the like. conventionally,
A method has been adopted in which a cleaning worker takes out a necessary amount of cleaning agent from a fiber drum containing about 50 kg of powder cleaning agent and puts it into a cleaning agent supply device. Attempts were made to avoid danger.

As one of the methods, there is a method of directly supplying a liquid cleaning agent into a cleaning tank using a pump. Although this method has been improved in that the cleaning agent does not directly touch the human body, it has a drawback that a sufficient cleaning effect cannot be obtained because the active ingredient of the liquid cleaning agent is smaller than that of the powder cleaning agent. Have.

There is also a cartridge type in which about 5 kg of a powder detergent is put in a container. This is a system in which a cleaning agent cartridge is loaded into a supply device, hot water is injected from a lower portion of the supply device to dissolve the cleaning agent, and the dissolved solution is supplied to the cleaning tank. In this case, since the powder detergent is used, the amount of the active ingredient is ensured, and sufficient detergency can be expected. However, there is a risk that the powder detergent solidifies in the container, resulting in poor dissolution of the detergent.

Further, Japanese Patent Publication No. 59-4480 and Japanese Unexamined Patent Publication No.
In JP 84500 and the like, a cartridge-type cleaning agent in which 4 to 5 kg of a solid hydration cleaning agent is cast and filled in a cleaning container has been devised. This solid hydration detergent cartridge
As in the case of the above-mentioned powder detergent cartridge, a method is adopted in which the cartridge is loaded into the supply device, hot water is injected from the lower portion of the supply device to dissolve the detergent, and the solution is supplied to the cleaning tank. However, the solid detergent has poor solubility, and in the initial stage of supplying a new detergent, there is a risk that the required amount of the detergent cannot be completely dissolved in a short time, resulting in insufficient concentration. Further, there is a problem that undissolved cleaning agent remains on the inner wall of the container.

On the other hand, the weight of both the powder detergent cartridge and the solid detergent cartridge must be suppressed to about 5 kg or less in consideration of the burden on the operator. Therefore, frequently used customers must replace the cleaning agent cartridge many times a day.

Further, since the cartridge container is usually made of plastic in consideration of durability and economy, there is a concern that the plastic may cause environmental damage.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a cleaning system which has good solubility, a sufficient concentration of a cleaning solution can be obtained, and has no trouble in changing the cleaning agent and does not use a cleaning agent container which causes environmental destruction. An object of the present invention is to provide a cleaning agent supply device for enabling the above.

[0010]

Means for Solving the Problems The present inventors have made intensive studies to solve the above-mentioned problems, and as a result, completed the present invention. The solid detergent supply device of the present invention is a supply device for distributing the solid detergent into the washing tank, and has a space for stacking and storing at least two or more solid detergents,
The bottom of the stored solid detergent at the bottom is immersed in the water or hot water that flows into the supply device, and the detergent is dissolved to produce a detergent aqueous solution. And is introduced into the washing tank through an overflow port provided in the washing tank.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. FIG. 1 is a perspective view showing an example of the solid detergent supply device of the present invention, and FIG. 2 is a sectional view thereof. FIG.
FIG. 2 is a perspective view showing an example of a solid detergent used in the solid detergent supply device of the present invention. The solid detergent of FIG. 3 is either unpackaged exposed or fully packaged with a water-soluble film.

1 and 2 show a cleaning agent supply apparatus 1 according to the present invention.
Has a space in which at least two or more solid detergents are stacked and stored, in which the basket 4 is provided inside the immersion tank 6. At least two solid detergents 3 that are not packaged or completely packaged with a water-soluble film are put into the basket 4 in the immersion tank 6 through the detergent inlet 9 so that the a or c surface faces downward. These are stacked and loaded.

Water or hot water is introduced into the immersion tank 6 by the water supply pipe 5 in order to dissolve the loaded solid detergent 3. The water or hot water introduced into the immersion tank 6 is filled in the immersion tank 6 until reaching the position of the detergent solution outlet 8.
Here, reference numeral 7 denotes a steam vent hole. From the bottom of the lowermost solid detergent among the solid detergents 3 loaded in the basket 4, 1 /
The portion having a volume of 4 to 1/2 is immersed in the water or hot water filled in the immersion tank 6, and the immersion portion of the solid cleaning agent 3 causes the water or hot water introduced from the water supply pipe 5 to swirl. The cleaning solution is dissolved in the immersion tank 6 to form a concentrated cleaning solution 10 and flows out of the cleaning solution outlet 8 into the cleaning tank through overflow.

The cleaning agent supply apparatus of the present invention exhibits good solubility even when the temperature and pressure of the supply water is low and the water pressure is low, so that a concentrated cleaning solution can be sent into the cleaning tank in a short time. In addition, the concentration of the cleaning agent in the cleaning tank can always be maintained at a predetermined concentration. Furthermore, since the solid detergent used in the present invention does not use a plastic container and uses disposable paper, vinyl, vinyl-coated paper, etc. as a packaging material, there is no fear of causing environmental destruction. preferable.

In the conventional cartridge type, 1
Each time the cleaning agent cartridge has been used, it has to be replaced with the next cartridge. However, in the cleaning agent supply device of the present invention, the solid cleaning agent is not filled, and one or two cleaning agent cartridges are used. After the use, the solid detergent can be loaded one after another, so that complicated replacement is eliminated. If the cleaning agent loading cylinder 2 is made transparent, the amount of the cleaning agent to be used can be known at a glance, so that it is easy to determine when to add the cleaning agent. In addition, since the basket 4 prevents the solid detergent from collapsing, there is no need to worry about clogging of the water supply pipe.

FIG. 4 is a perspective view showing another example of the solid detergent supply device of the present invention, and FIG. 5 is a sectional view thereof. In the method of dissolving and supplying a solid detergent with this detergent supply device, the package of the solid detergent is removed in the supply device, and the loaded solid detergent is dissolved and supplied by spraying and dipping. FIG. 6 is a perspective view showing a solid cleaning agent used in this method. The solid detergent shown in FIG. 6 is entirely packaged with a water-insoluble film or wrapping paper.

In the cleaning agent supply apparatus 1 of the present invention of this type, a column 11 is provided at the bottom of the supply apparatus, and the column type cleaning agent 3 having a central hole is inserted and loaded. That is,
The solid cleaning agent 3 entirely wrapped with a water-insoluble film or wrapping paper is placed such that the a or c surface is lowered and the support 11 in the supply device is inserted into the hollow portion d of the solid cleaning agent 3. It is loaded into the supply device from the cleaning agent inlet 9. At the time of insertion, the wrapping paper or film of the cleaning agent is partially torn by being inserted into the column 11, and further cracks are spread by pulling the wrapping paper or the film upward, and the wrapping paper or the film is peeled from the solid cleaning agent 3. At this time, the solid cleaning agent 3 is temporarily fixed by the movable claw 12 attached to the column 11, and after the wrapping paper or the film is peeled off,
Due to its own weight and / or the weight of the solid detergent superimposed thereon, it sinks downward and is loaded into the basket 4.

In order to dissolve the loaded solid detergent 3, water or hot water is sprayed from a horizontal spray spray nozzle 13 attached to the tip of the water supply pipe through the water supply pipe 5 to fill the immersion tank 6. The lowermost solid cleaning agent 3 in the basket 4 is dissolved by spraying the spray nozzle 13 and dipping in water or hot water filled in the immersion tank 6 to form a concentrated cleaning agent solution 10 and the cleaning agent. The solution flows out from the solution outlet 8 into the washing tank by overflow.

In this method, the disposable packaging material enclosing the solid cleaning agent 3 can be removed by a simple operation of pulling the solid cleaning agent 3 by inserting it into the column 11, and the solid cleaning agent 3 is supplied to the supply device 1 after it enters the supply device 1. Because it is exposed, there is no danger of touching the human body directly during the operation of removing the solid detergent. Many cleaning agents used in the food service and food industries
Sodium hydroxide and potassium hydroxide are contained in high concentration, and handling safety must be ensured, but this method is very safe. Further, by using both spraying and immersion, the dissolution of the solid detergent can be accelerated, and the concentration of the detergent in the washing tank can be brought to a predetermined concentration in a short time.

FIG. 7 is a perspective view showing still another example of the solid detergent supply device of the present invention, and FIG. 8 is a cross-sectional view thereof. In this system, the solid detergent is easily supplied from the side of the supply device. After rolling and loading, the solid detergent is dissolved and supplied by spraying and dipping. The solid detergent used in this method may be any of the detergents shown in FIG. 3 or FIG.

In this method, the solid cleaning agent 3 which is not wrapped or wrapped with a water-soluble film has its b-side face down, and is stacked and loaded into the basket 4 in the immersion tank 6 from the cleaning agent inlet 9. Is done. The loaded solid detergent 3 is
It is dissolved by water or hot water sprayed from a spray nozzle 13 attached to the side surface of the immersion tank 6, becomes a concentrated detergent solution 10, and flows out of the detergent solution outlet 8 into the washing tank by overflow.

In this method, the upper surface (a surface) of the solid detergent
It is not necessary to load the device while holding it, and the device is loaded while supporting it between the a-plane and the c-plane. A of solid detergent
The distance between the plane and the c-plane is preferably 15 cm or less, and 7 to 10 cm is the easiest to sandwich. Each piece weighs 3 kg or less, preferably 2 kg
The following is good.

Preferred (highly soluble) solid detergents used in the solid detergent supply device of the present invention include:
10 to 50% by weight (preferably 25 to 45% by weight) of an alkali hydroxide such as sodium hydroxide or potassium hydroxide, 0.1 to 10% by weight (preferably 0.5 to 3% by weight) of a surfactant, ~ 55 wt% (preferably 20-40 wt%) and water 5-40 wt% (preferably 10-25 wt%)
It contains.

[0030]

When the solid cleaning agent supply device of the present invention shown in FIGS. 1 and 2 is used, the solid cleaning agent is immersed and dissolved in a dipping bath filled with water or hot water. A cleaning solution is obtained. Further, the solid detergent may be used in a form exposed without packaging, in a form completely packaged in a water-soluble film, or in a form completely packaged in a water-insoluble film or wrapping paper. Even with the last form of solid detergent, the packaging is removed when it is loaded into the dispenser, eliminating the need to remove empty containers when loading new detergent as with conventional cartridge detergents. be able to. Further, environmental pollution caused by the plastic container can be prevented. In addition, since two or more solid detergents of 3 kg or less that are easy to handle are stacked, there is no need to replace them with a new detergent cartridge when the detergent is empty as in the cartridge type. I just need to load it,
There is an advantage that the workability is good and that the concentration of the detergent can be always kept constant. In addition, the use of the basket prevents the solid detergent from collapsing, and there is no risk of clogging the water supply pipe.

When the solid cleaning agent supply device of the present invention shown in FIGS. 4 and 5 and the donut type solid cleaning agent shown in FIG. 6 are used, the solubility of the cleaning agent is further improved. That is, the dissolution of the cleaning agent by spraying from a spray nozzle provided on the waterline of the immersion tank brings about a synergistic effect with the immersion dissolving action, and uniformly dissolves the cleaning agent from the bottom. In addition, this supply device can remove the cleaning agent wrapped in a water-insoluble film or wrapping paper at the same time as the supply, so that container pollution can be prevented while ensuring safety, and furthermore, replacement of empty containers. Work can be omitted.

When the solid detergent supply device of the present invention shown in FIGS. 7 and 8 is used, similarly to the case where the supply device of FIGS. 4 and 5 is used, the spray from the spray nozzle provided on the waterline is used. The dissolving action of the cleaning agent by spraying exerts a synergistic effect with the immersion dissolving action, which mainly functions in dissolving the cleaning agent. Further, the operation of loading the cleaning agent is significantly improved.

There are many women who are engaged in operations such as dishwashing in the food service industry, that is, users of the cleaning agent supply device. Conventional cartridge-type solid casting detergent,
Each cartridge-type powder detergent weighed 4 to 5 kg and was too heavy for a woman to wear with one hand. In order to reduce the weight of the cartridge type, the frequency of replacement of the cleaning agent is further increased, and the labor of the operator is not reduced.

In the solid detergent supply device of the present invention, the loading of the solid detergent is performed not by replacing the cartridge, but by replacing the cartridge.
Only a solid detergent that is unpacked or packaged is put in, and several solid detergents can be used continuously, so that one solid detergent can be made smaller and lighter than conventional products. .
