In addition, a liquid jet flow generating mechanism including a cleaning chips suction pipe communicated with the vicinity of the tip of the nozzle portion of the enlarged diameter pipe can be used.

The above-described mixing and spraying mechanism of the cleaning liquid and the cleaning material chips includes a nozzle section for generating a jet flow from a nozzle opening having a reduced diameter of the cleaning liquid supply pipe, an expanded pipe formed ahead of the nozzle section, and an expanding pipe. A cleaning material chips suction pipe communicated with the vicinity of the nozzle end of the diameter pipe, and an opening at one end in the vicinity of the nozzle section of the enlarged diameter pipe or at the downstream of the junction of the cleaning material chips suction pipe, and the like.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION The washing liquid used in the article washing method of the present invention can be water or hot water, as well as generally used detergent solutions. Further, by electrolyzing water, an aqueous solution of a chloride salt such as sodium chloride, or an aqueous solution of a silicate such as sodium metasilicate in a diaphragm electrolytic cell, strong alkaline water having a pH of 9.5 or more is generated in the cathode chamber of the electrolytic cell. However, the strong alkaline water has a strong detergency and is more suitable as a cleaning solution used in the cleaning method of the present invention. Accordingly, the cleaning liquid used in the cleaning method of the present invention contains water, hot water, a detergent solution or electrolytically generated strong alkaline water having a pH of 9.5 or more, and one kind thereof may be used, or two or more kinds thereof may be used. You may mix and use.

[0016] The article cleaning method according to the first aspect of the present invention comprises:
A strong alkaline water having a pH of 9.5 or more obtained by electrolyzing water, an aqueous solution of a chloride salt such as sodium chloride, or an aqueous solution of a silicate such as sodium metasilicate in a diaphragm electrolyzer is used as a cleaning solution, and air is added thereto. Is mixed to generate a gas-liquid mixed jet, and the gas-liquid mixed jet is caused to collide with the surface of the article to be cleaned for cleaning.

Strong alkaline water having a pH of 9.5 or more obtained by electrolyzing water, an aqueous solution of a chloride salt or an aqueous solution of a silicate dissolves oil and the like well and has a strong detergency. Also, with the introduction of air,
When the bubbles are mixed, a film is formed on the surface of the bubbles, thereby increasing the cleaning effect. That is, in this cleaning method, the bubbles and the cleaning liquid jetting force that is energized by the bubble pressure and the bubble surface tension act where the stain is easily dissolved by the strong alkaline water. In particular, since the collision of the cleaning water with the object to be cleaned is intermittently performed by bubbles in the cleaning jet stream, a physical cleaning effect occurs, and dirt is effectively removed without using cleaning material chips described later. You.

Generally, dirt such as oil attached to tableware and the like adheres as a layer to the surface of the tableware. Therefore, simply spraying the above-mentioned cleaning solution on the tableware slides on the surface of the dirt layer, and the dirt layer is removed. It is difficult to penetrate inside. In addition, stubborn dirt such as burnt spots cannot be removed only by spraying the cleaning liquid. Therefore, although a large amount of cleaning liquid is used and strong jetting energy is applied, dirt is not easily removed and an efficient cleaning effect cannot be obtained. Therefore, the second aspect of the invention is to provide a chemical action of the cleaning liquid and a physical action such as grinding, polishing, brushing, frictional or wiping by the surface tension of the bubbles and the cleaning material chips.

That is, the second cleaning method of the present invention comprises:
Along with water, hot water, a detergent solution, or a cleaning solution consisting of strongly alkaline water having a pH of 9.5 or more generated by electrolysis or a mixture of two or more thereof, chips (small pieces) of a cleaning material having a grinding, polishing, brush or wiping function are removed. A cleaning liquid, a cleaning material chip, and a mixture of air are used as a gas-liquid mixed jet stream to collide with the surface of the article to be cleaned.

By the way, the cleaning liquid and the cleaning material chips may be premixed and sent together with air at a high pressure to be discharged as a gas-liquid mixed jet, but a pump is generally used for high pressure feeding. Pumping a fluid containing solid cleaning material chips often causes clogging and failure of the pump, which is not preferable.

Therefore, in a more preferred embodiment of the cleaning method according to the present invention, as will be described later with reference to FIGS. 3, 4 and 5, the air is converted into a gas-liquid mixed jet by a pump or the like, and the air is generated. The cleaning material chips are sucked and fed at a high pressure by the gas-liquid mixed jet flow of the cleaning liquid and the air, and the cleaning liquid, the cleaning material chips and the air are mixed and washed with the jet pressure of the gas-liquid mixed jet flow. I try to collide with things. In this feeding method, only the cleaning liquid is pumped, and the cleaning material chips are sucked near the jet nozzle downstream of the pump and mixed with or accompanying the cleaning liquid, so that the cleaning material chips do not interfere with the operation of the pump.

In addition, as a method of joining the cleaning material chips to the flow of the cleaning solution, the cleaning solution is sent out from the high-pressure nozzle by a jet flow, and the cleaning material chips are sucked into the cleaning solution jet flow.
There is a liquid jet method to join. Although it is of course possible to adopt this method, the cleaning liquid is sent out from the nozzle by an injection (jet) flow, and air is sucked into the vicinity of the nozzle of the injection flow to generate a mixed injection flow of the cleaning liquid and air. It is more preferable to use a gas-liquid mixing jet method in which the cleaning material chips are sucked and merged. In the gas-liquid mixing jet method, a strong suction force is generated, and a stable suction / merging action of the cleaning material chips can be obtained.

Next, an embodiment of an automatic cleaning apparatus for carrying out the method of the present invention will be described with reference to the accompanying drawings. In this embodiment, an automatic cleaning apparatus for cleaning tableware will be described as an example. Generally, this type of automatic cleaning device is one that sprays a cleaning liquid from a fixed spray nozzle onto tableware conveyed along a cleaning line such as a belt conveyor or a rotary table, and one that is stationary on a support base. There is a type in which a cleaning liquid is sprayed from a movable nozzle that rotates or slides, and the apparatus of the present invention is applied to any of them.

FIGS. 1 and 2 show an automatic washing apparatus of the former type according to the present invention, which has tableware conveying means 1 such as a belt conveyor for conveying tableware along a washing line. The tableware transporting means 1 is for transporting a large number of tableware (not shown) in a direction indicated by an arrow in FIG.

A cleaning liquid composed of strong alkaline water having a pH of 9.5 or more or a mixture thereof is sent to the injection port 4.

In addition, the cleaning liquid supply pipe 6 of the apparatus of the present invention, in addition to the cleaning liquid, feeds and transports the cleaning material chips 3 described later, and the cleaning liquid 2 and the cleaning material chips 3 are supplied from the injection port 4. In a mixed state, it is sprayed toward tableware in the washing line.

For this purpose, the supply line 6 must supply a mixture of the cleaning liquid and the cleaning material chips 3. However, if the premixed product is sent out by the pump 5, clogging or failure occurs. Therefore, it is necessary to join the cleaning material chips 3 to the flow of the cleaning liquid on the downstream side of the pump 5 and eject the chips. For this reason, the apparatus of the present invention generates the cleaning liquid in the cleaning liquid supply pipe 6 into the jet flow on the downstream side of the pump 5 of the cleaning liquid supply pipe 6 by the pump 7 or the like, and the outside of the system by the suction action of the jet flow.

Are connected to each other. In this case, preferably, the suction pipe 8 is opened to a large-diameter pipe 11 near the tip of the nozzle section 10 where the velocity of the jet flow is high.

According to this configuration, a pressure difference is generated in the enlarged diameter pipe 11 ahead of the nozzle portion 10, so that air is sucked from the suction pipe 13. At this time, cavitation in the jet flow is prevented by the intake air bending around the jet flow, and the jet flow is transferred to the downstream pipe while maintaining the shape and speed at the time of injection. storm in. For this reason, the suction line 8
The cleaning material chips 3 therein are sucked up by the jet flow of the cleaning liquid supply pipe 6 with a strong suction force, and are sent out at a high speed together with the jet flow of the cleaning liquid. Therefore, the cleaning liquid 2, the air, and the cleaning material chips 3 collide with the surface of the tableware from the injection port 4 in a mixed state.

As described above, the apparatus shown in FIG. 6 has a function of recovering the cleaning material chips 3 from the cleaning casing 26, and can be used by switching to an apparatus for cleaning only with a cleaning liquid without using cleaning chips.

Further, in the apparatus shown in FIG. 6, the cleaning material chip collecting tray 15 can be vibrated from the solid line position to the imaginary line position with the pivot pin 40 as a fulcrum. When the cleaning material chips are not used, one inclined lower end of the collecting tray 15 communicates with the common suction pipe 8, and when the cleaning material chips are not used, the other inclined lower end of the collecting tray 15 faces the waste removal tray 41 of the cleaning casing 26. It is inclined.

Although the washing apparatus shown in FIGS. 1, 2 and 6 is used as an apparatus for washing tableware, the present invention is not limited to this, and can be widely used for washing foods and other general objects to be washed.
