Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning device for cleaning cutting boards, floor surfaces, etc. used for cutting foodstuffs such as meat.

[0002]

2. Description of the Related Art In a meat processing facility or the like, meat is placed on a cutting board, cut into a predetermined size by a cutting blade, and shipped. A great deal of force is applied to such cutting blades for cutting meat, and thus countless cutting tool scratches are formed on the surface of the cutting board at all angles, directions, depths, and sizes.

However, gravy, blood, etc. infiltrate and stay in the inside of such a cut wound, and even if the cutting board is simply washed with water, these cannot be completely washed off.
Even if a scrubbing brush or a brush is used, the width of the blade damage is smaller than the diameter of the hair of the scrubbing brush or the brush, so it is not possible to sufficiently wash off the gravy etc. remaining in the depth of the blade damage, which causes various germs. There was the inconvenience of urging people to become unsanitary.

On the other hand, in order to solve such inconvenience, today, after cutting meat or the like, high-pressure water sent from a high-pressure pump is jetted from the washing nozzle onto the surface of the cutting board at high pressure, A simple cleaning method that can easily and quickly wash off the meat juice or the like that has adhered to or remains in the cut wound is widely adopted.

[0005]

However, in such a conventional method for cleaning a cutting board by jetting high-pressure water, the water jetted onto the cutting board rebounds from the surface of the cutting board and is scattered around. , The surrounding walls and floors,
In addition, there is a problem in that the surrounding environment may be deteriorated because, for example, stains may be attached to the equipment and the like to make it unsanitary, and water may be accumulated in the vicinity.

The present invention focuses on the above-mentioned conventional problems and solves them. The purpose of the present invention is that water sprayed on a surface to be cleaned such as a cutting board is splashed from the surface to be cleaned to the periphery. It is an object of the present invention to provide a cleaning device capable of cleanly removing dirt adhering to the inside of minute scratches on a surface to be cleaned while preventing it from scattering.

SUMMARY OF THE INVENTION The present invention has been made in view of the above objects, and the gist of the present invention is to provide an upper cover that forms an upper chamber and the upper cover connected to the upper cover. A lower cover forming a lower chamber communicating with the chamber, an opening provided at the bottom of the lower chamber, a drain port provided at a side of the lower chamber, and an upper chamber provided at the upper cover. A cleaning nozzle for injecting a cleaning liquid onto the surface to be cleaned facing the opening through a communication portion provided between the upper chamber and the lower chamber, and the cleaning nozzle ejects the cleaning liquid to the upper chamber and the lower chamber. In the cleaning device, the generated air flow is used to collect the splashed water that bounces off the surface to be cleaned and to cause it to flow out from the drain port.

According to this aspect, the high-pressure cleaning liquid such as hot water sprayed from the cleaning nozzle is sprayed onto the surface to be cleaned such as a cutting board on which the lower cover is placed, so that the surface of the surface to be cleaned or this surface is cleaned. It is possible to completely wash off the dirt and other substances that have entered into the scratches by the jet pressure, and even if the cleaning liquid that hits the surface to be cleaned splashes at this time, it is rectified inside the lower cover to directly go outside from the lower cover. It can be prevented from scattering. Further, the splashed cleaning liquid can be promptly discharged from the drain port on the side portion of the lower cover by the air flow generated by the jetting.

Another aspect of the present invention is a cleaning device characterized in that the upper cover is provided with an intake port for introducing outside air into the upper chamber.

According to this aspect, when the cleaning liquid is sprayed from the cleaning nozzle to the lower chamber, the negative pressure in the upper chamber makes it difficult for the cleaning liquid to flow to the drain port. This can be avoided, and thus the cleaning liquid after cleaning can be prevented from staying on the surface to be cleaned in the lower chamber.

Another aspect of the present invention is that a plurality of the cleaning nozzles are installed on the upper cover so that the cleaning liquid spray patterns from the cleaning nozzles partially overlap with each other on the surface to be cleaned. The cleaning device is characterized in that

According to this aspect, by using a plurality of cleaning nozzles at the same time, it is possible to quickly and uniformly clean a large area at a time, and the cleaning work efficiency can be remarkably increased.

Another aspect of the present invention is a cleaning apparatus characterized in that a rectifying section for rectifying the splashed water reflected from the surface to be cleaned is provided in the lower cover.

According to this aspect, the droplet-shaped or granular cleaning water scattered from the surface to be cleaned is once received by the rectifying unit and then flows downward, thereby generating a water flow and promptly flowing to the drainage port. I can guide you.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below.
It will be described with reference to the drawings. FIG. 1 is a front view conceptually showing the entire cleaning apparatus of the present invention. In FIG. 1, reference numeral 1 is an upper cover, and 2 is a lower cover integrally provided under the upper cover 1. The lower cover 2 has a shape that expands downward in a skirt shape in appearance.

As shown in FIGS. 2 and 3, the upper cover 1 has a rectangular parallelepiped appearance, while the lower cover 2 has a disk shape, which are formed as a molded product of a metal plate, a metal material, a synthetic resin or the like. And welded if necessary. It should be noted that the upper cover 1 and the lower cover 2 may be integrally molded.

Further, the upper cover 1 and the lower cover 2
Form an upper chamber 3 and a lower chamber 4, respectively, as shown in FIGS. 2 and 4. Top plate 1 of the upper cover 1
A cleaning nozzle device 5 is attached to a. This cleaning nozzle device 5 includes a coupler socket 6, a cheese 7 and an elbow 8 with different diameter nipples 9 and same diameter nipples 10.
It consists of ones connected by.

Each of the cheese 7 and the elbow 8 is attached with a cleaning nozzle 11, 12 facing the inside of the upper chamber 3. Incidentally, these cleaning nozzles 11, 1
2 is arranged so that the injection axis of the cleaning liquid is directed vertically downward. Each of the cleaning nozzles 11 and 12 sprays the cleaning liquid linearly on the surface 13 to be cleaned, and the spray pattern spreads, that is, the length of the line of the cleaning liquid sprayed on the surface 13 to be cleaned is arbitrarily adjusted. You can do it. Further, the cleaning nozzles 11 and 12 are arranged such that the spray patterns of the cleaning liquid partially overlap with each other on the surface 13 to be cleaned such as the cutting board M. As a result, uneven cleaning on the surface 13 to be cleaned is eliminated, and efficient cleaning can be performed. In addition,
It is also possible to adjust the spray pattern of the cleaning liquid on the surface to be cleaned to a circular shape other than dots or other shapes.

A high pressure pump 15 is connected to the coupler socket 6 via a pressure resistant hose 14. The high-pressure pump 15 is driven by, for example, a single-phase AC 200V as a power source, and hot water supplied from the outside through a water tap 16 and a pipe 17 is washed through the coupler socket 6, the cheese 7 and the elbow 8. 11, 1
2 to supply high pressure. As a result, high-pressure hot water is jetted from the cleaning nozzles 11 and 12 at high speed into the upper chamber 3 inside the upper cover 1 and the lower chamber 4 inside the lower cover 2.

At least one side surface of the upper cover 1 is provided with an intake port 18 communicating with the inside and outside of the upper chamber 3. The intake port 18 prevents negative pressure in the upper chamber 3 and the lower chamber 4 due to hot water injection and drainage from the cleaning nozzles 11 and 12, and an injection pattern of hot water or the like injected with the negative pressure. It prevents turbulence and unstable and inefficient drainage flow.

Between the upper cover 1 and the lower cover 2, the upper chamber 3 and the lower chamber 4 are communicated with each other, and the outside air taken in from the intake port 18 is smoothly moved to the drain port 20 side described later. The communicating portion 19 for guiding is formed so as to include the passage area of the jet water. The communication part 1
Reference numeral 9 denotes a predetermined opening area capable of creating a flow of air created by the injection of the hot water.

Further, a drain port 20 communicating with the inside and outside of the lower chamber 4 is provided on the side surface (outer peripheral surface) of the lower cover 2, and the surface 13 to be cleaned is sprayed with the hot water by the drain port 20. The washed water is collected and the lower cover 2
Is discharged to the outside. The wash water is discharged (outflowed) from the drain port quickly and smoothly by using the flow of the intake air introduced into the upper chamber 3 and the lower chamber 4 as described above.

At the bottom of the lower cover 2, there is provided an opening 21 that opens to the surface to be cleaned 13 such as the cutting board M to be cleaned or the floor. This opening 21 communicates with the lower chamber 4. To do. The upper portion of the lower chamber 4 has a diameter larger than the diameter of the opening portion 21, that is, the diameter of the opening portion 21 is tapered upward to form a recess 22. There is. Therefore, the tapered recess 22 forms a rectifying unit that functions to receive splashes of the hot water splashed against the surface to be cleaned 13 and rectify the splashes, and to flow the hot water along the tapered surface T. There is.

The rectifying section for rectifying and flowing down the scattered cleaning water as the cleaning liquid is, in addition to the depression 22, a plurality of corrugated surfaces such as corrugations formed on the inner surface of the lower chamber 4. It can be arbitrarily adopted.

Therefore, in the cleaning apparatus having such a structure, in order to perform the cleaning operation, the cleaning apparatus main body including the upper cover 1 and the lower cover 2 is first cleaned with a cutting board or floor surface to be cleaned. It is placed on the surface to be cleaned such as, for example, the surface 13 to be cleaned of the cutting board M in this case.

Then, the water tap 16 is opened to feed hot water as a cleaning liquid from the external water heater to the high-pressure pump 15 side through the pipe 17. Further, the high-pressure pump 15 is driven by turning on a start switch (not shown), and hot water having a high pressure is sent to the cleaning nozzle device 5. Therefore, hot water is spread from the two cleaning nozzles 11 and 12 of the cleaning nozzle device 5 with a certain spread.
And high-pressure injection is performed vertically downward toward the lower chamber 4.

Furthermore, these upper chamber 3 and lower chamber 4
The high-pressure jetted water is sprayed linearly on the surface 13 to be cleaned, which is the surface of the cutting board M facing the opening at the bottom of the lower cover 2, with the aforementioned spread. For this reason, the high-pressure jet water will directly wash off stains remaining inside the fine grooves, deep grooves and the like formed on the surface of the cutting board M, such as blade damage.

At this time, the cleaning liquid sprayed from the two cleaning nozzles 11 and 12 partially overlaps each other on the surface of the cutting board M and becomes a longer linear shape. Therefore, in the lower cover 2, a flow of the cleaning liquid occurs around the portion where the cleaning liquid is linearly sprayed on the cutting board M, whereby the dirty cleaning liquid after cleaning is promptly and efficiently directed to the discharge port. Be guided.

In addition, the cleaning water thus cleaning the surface of the cutting board M is splashed to the periphery by spraying the hot water vertically downward to the surface of the cutting board M. However, this bounce is prevented from directly going out of the lower chamber 4 by the lower cover 2, and most of the bounce is once received in the tapered recess 22 and then flows down along the tapered surface T. Is rectified to do.

Accordingly, the cleaning water thus rectified in this manner is again sent on the surface of the cutting board M toward the drain port 20, and finally discharged to the outside of the lower chamber 4. Then, by continuing such a cleaning operation for a certain period of time, the dirt inside the blade scratches of the cutting board M covered by the lower chamber 4 can be completely washed off together with the dirt inside the lower chamber 4, which is extremely high. The hygiene level can be secured.

By the way, during such a cleaning operation, high-pressure hot water is sprayed from the cleaning nozzles 11 and 12 at a high speed and passes through the upper chamber 3, the communicating portion 19 having a small opening area, and the lower chamber 4. And is projected on the surface of the cutting board M.
At this time, since the inside of the upper chamber 3 is pulled to a negative pressure, outside air is introduced into the upper chamber 3 through the intake port 18, and this outside air is further rapidly pressed into the lower chamber 4 through the communicating portion 19.

Therefore, the outside air that is press-fitted into the lower chamber 4 collides with the surface of the cutting board M and diffuses to the surroundings, and as described above, the jet water projected onto the surface of the cutting board M is discharged. After being diffused in the direction indicated by (1), while being reflected on the inner circumference of the lower chamber 4, a water flow is formed together with the water that has flowed down from the tapered surface T, and the water flow is promptly discharged toward the drainage port 20. In this way, the cleaning operation with the jet water and the draining operation of the cleaning water after the cleaning with the intake and exhaust of the outside air can be simultaneously performed in parallel.

If the cutting board M is large, the washing machine body is moved onto the cutting board M without moving the cutting board M, so that the washing water after washing is scattered around the work place and is contaminated. It is possible to quickly and completely clean a cutting board or floor having a large surface 13 to be cleaned while preventing the above. In addition, in order to facilitate the movement operation of the main body of the washing machine, a handle (not shown) for driving operation, to which a starting switch of the high-pressure pump 15 is attached, is attached to this.

Further, in the above-described embodiment, as shown in FIG. 4, the case where the upper portion of the lower chamber 4 is tapered upward with respect to the diameter of the opening 21 has been described. The two peripheral walls (side walls) may have a uniform and thin thickness, and may be tapered downward in the lower chamber 4. In this case, the cleaning area of the surface 13 to be cleaned facing the opening 21 can be increased, and the efficiency of the cleaning operation can be improved.

Although FIG. 5 shows the direction of water flow when the inner peripheral surface of the lower chamber 4 is circular, the inner peripheral surface of the lower chamber 4 has a parabolic shape depending on the flow velocities of the wash water and the external air flow. , By selecting a polygonal shape, the drainage efficiency and the cleaning efficiency can be set arbitrarily.

Further, it is desirable to arbitrarily select and use the temperature of the cleaning water and the type of the cleaning liquid according to the type of the object to be cleaned. Furthermore, by connecting a bellows hose or the like to the drainage port 20, it is possible to guide the wash water (dirty water) after washing to a predetermined portion except the upper surface of the cutting board for proper drainage treatment.

[0037]

As described above, according to the present invention, through the communication portion provided between the upper chamber and the lower chamber, from the cleaning nozzle on the upper cover to the cutting board or the like facing the opening of the lower chamber. In addition to spraying cleaning water on the other hand, by using the air flow generated inside the upper chamber and the lower chamber to guide the cleaning water after cleaning the cutting board etc. to the outside of the lower cover, While preventing the wash water from splashing to the
It is possible to completely wash off the dirt adhering to the inside of the lower cover and the dirt that has entered the scratches on the surface of the cutting board and the like.

Further, according to the present invention, since the upper cover is provided with the intake port for introducing the outside air into the upper chamber, it is possible to prevent the upper chamber from falling into a negative pressure due to the injection pressure of the water sprayed from the cleaning nozzle. Yes, thus smoothing the flow of air to the upper and lower chambers. As a result, there is a remarkable effect that the flow of the washing water in the lower chamber is smoothed, a stable water flow is created toward the drain port, and the water can be quickly drained.

Further, according to the present invention, the plurality of cleaning nozzles are arranged on the upper cover so that the spray patterns of the cleaning liquid from the cleaning nozzles partially overlap on the surface to be cleaned. There is a remarkable effect that a large area can be washed quickly and uniformly.

Further, according to the present invention, in the lower cover,
By providing a rectifying unit that rectifies the splashed water reflected from the surface to be washed, the drop-like or granular washing water that is scattered from the surface to be washed is once received by the rectifying unit and then smoothly flows downward. As a result, a remarkable effect is produced in that a water flow can be generated and quickly guided to the drainage port.
