Japanese Patent No. 4414482

In the present invention, not only an object to be cleaned having a small specific gravity, but also an object to be cleaned having a large specific gravity can be easily turned upside down to repeatedly perform up and down inversion, and as a result, a sufficient cleaning effect can be obtained. An object of the present invention is to provide a food cleaning device.

In order to solve the above problems, the present invention employs the following configuration.
That is, the food washing apparatus according to claim 1 is:
A washing water tank (2) for containing washing water therein;
An overflow edge (22) formed at the upper edge of the washing water tank (2);
A filtered water tank (7) for allowing washing water containing dust overflowed from the overflow edge (22) to flow and filter;
A washing basket (9) provided with a bottom screen (92) at the bottom of the cylindrical body (90) and detachably mounted in the washing water tank (2);
A circulation pump (8) for pumping the filtered wash water of the filtered water tank (7);
A pressure water pipe (51) extending from the circulation pump (8) to the center of the bottom of the washing water tank (2) and having a spout (55) opening upward at the tip;
An annular air pipe (6) connected to the blower (60) at the bottom of the washing water tank (2) so as to surround the spout (55);
At least three aeration nozzles (6a) attached to the annular air pipe (6) so as to be arranged at least around the jet outlet (55) are provided.

The food washing apparatus according to claim 2 is the food washing apparatus according to claim 1, wherein the bottom screen of the washing basket (9) is positioned directly above the jet port (55) of the pressure water pipe (51). The water flow blocking plate (92a) is formed at the center of (92).

The food washing apparatus according to claim 3 is the food washing apparatus according to claim 1 or 2, wherein the inclination is for generating a vortex in the water flow inside the spout (55) formed at the tip of the pressure water pipe (51). It was set as the structure provided with the board (56).

The food cleaning device according to claim 4 is the food cleaning device according to claim 1, 2 or 3, wherein the aeration nozzle (6 a) is formed such that the upper end side is inclined in the circumferential direction to generate a vortex in the water flow. It was set as the structure.

The food washing apparatus according to claim 5 is the food washing apparatus according to any one of claims 1 to 4, wherein the water flow blocking plate (58) is configured to block the pressure water pipe (51) from above the jet port (55). It was set as the structure attached.

The food washing apparatus according to the present invention (Claim 1) extends from the circulation pump provided in the filtration water tank to the center of the bottom of the washing water tank, pipes a pressure water pipe, and opens upward at the tip of the pressure water pipe to form a spout And an annular air pipe is connected to a blower at the bottom of the washing water tank so as to surround the jet outlet, and at least three pipes are arranged in at least three directions around the jet outlet. There is a feature in the configuration with the aeration nozzle attached.

That is, the cleaning method is a combination of a water flow caused by the force of water jetted upward from the jet outlet of the pressure water pipe and bubbles jetted upward from at least three aeration nozzles around the jet outlet.

As a result, the food to be cleaned is pushed upward in the central portion of the cleaning tank by the water flow from the water jet, and then tries to sink around the cleaning water tank. In order to push up from the bottom, food is beaten by the water flow and bubbles, and the ups and downs are repeated.
Therefore, even a food having a high specific gravity and easily sinks in water can be evenly and uniformly washed, and a sufficient washing effect can be obtained.

Next, the food washing apparatus of the present invention (Claim 2) has a central portion of the bottom screen of the washing basket so that the outlet of the pressure water pipe is opened upward and is positioned directly above the outlet. A water flow blocking plate is formed.

If a jet port that opens upward is formed at the tip of the pressure water pipe, the main flow of the water flow is generated upward, making it difficult to uniformly distribute the water flow over the entire washing water tank.
Therefore, a water flow blocking plate is formed in the central portion of the bottom screen of the washing basket, and the main flow of the water flow that flows upward is blocked by the water flow blocking plate, thereby generating a radial water flow, whereby the upward water flow is generated in the washing water tank. It can be uniformly dispersed throughout, and uniform cleaning can be performed evenly.

In addition, as a means for blocking the water flow flowing upward from the jet outlet, as described above, in addition to forming the water flow blocking plate at the central portion of the bottom screen of the washing basket, the water flow cutoff is performed so that the pressure water pipe is blocked above the jet outlet. A plate may be attached (Claim 5).

Further, if an inclined plate is provided inside the jet outlet formed at the tip of the pressure water pipe (Claim 3), the water flow generated upward from the jet outlet can be rotated by a vortex.
As a result, the object to be cleaned can be dispersed from multiple directions by the upward water flow and the rotating water flow, and the cleaning effect can be further improved.

Further, when the aeration nozzle is formed so that the upper end side is inclined in the circumferential direction so as to generate a vortex in the water flow (Claim 4), the bubbles ejected from the aeration nozzle can be rotated by the vortex.
As a result, the object to be cleaned can be dispersed from multiple directions, and the cleaning effect can be further improved.

You may form in a container or a square container.

An upper end edge of the washing water tank 2 is formed at the overflow edge 22 on the entire periphery, and an outward flange surface 20 is formed on the entire outer periphery of the overflow edge 22. A water collection port 23 that is wider than the diameter is formed.

In the embodiment, an arc-shaped flange surface 20a having a certain width is formed on the half-circumferential portion of the cleaning water tank 2, and the other half-circumferential portion of the cleaning water tank 2 is extended tangentially from both ends of the arc-shaped flange portion 20a. 20b and 20b are formed, and the entire width of the parallel flange portions 20b and 20b is formed as the width of the water collecting port 23. Thereby, a water collection area can be taken widely.

The water collection port 23 is connected to a bowl-shaped flow path 24, a recovery pipe 25 is connected to the bottom of the bowl-shaped flow path 24, and the recovery pipe 25 is extended into the filtered water tank 7.

The filtered water tank 7 is made to flow by washing water containing dust and the like overflowing from the overflow edge 22 of the washing water tank 2 and is formed in a rectangular container.

Inside the filtered water tank 7, a submersible pump is installed as a circulation pump 8, and the wash water in the filtered water tank 7 is circulated to the wash water tank 2 by pressure feeding by the circulation pump 8. As this circulation pump 8, a low-pressure pump can be used.
The filtered water tank 7 is always supplied with water by a water supply pipe 73 during the cleaning operation, and dirty cleaning water is discharged from the overflow hole 72 to the outside of the apparatus.

A filtration mesh bag 71 is detachably attached to the discharge port 26 in the filtered water tank 7 of the recovery pipe 25.
The mesh bag 71 for filtration is formed of a mesh made of cotton, hemp, or synthetic resin material, and is detachably attached by covering and tying the mouth portion over the discharge port 26.

Accordingly, the overflow water (wash water) that has overflowed the overflow edge 22 of the wash water tank 2 flows through the flange surface 20 and flows into the water collection port 23, and further passes from the bowl-shaped flow path 24 through the recovery pipe 25 to the filtered water tank 7. The dust is removed and filtered by the mesh bag 71 for filtration.
In addition, illustration of the filtration water tank 7 is abbreviate | omitted in FIG.

Further, since the overflow edge 22 is formed over the entire upper edge of the washing water tank 2, it can be overflowed from anywhere in the washing water tank 2, and the washing water containing dust etc. stays without overflowing. There is no such a thing.
Moreover, since the opening width of the water collection port 23 is formed wider than the diameter of the washing water tank 2, the water collection area can be increased, and the flow of washing water including dust etc. can be smoothed and reliably filtered. It can flow into the water tank 7.

A pressure water pipe 51 is extended from the circulation pump 8 to the center of the bottom of the washing water tank 2, and an injection pipe 55 a as shown in FIG. 4 is attached to the tip of the pressure water pipe 51 by screwing of a screw portion 57. A jet outlet 55 opening upward is formed in the jet pipe 55a.

As shown in FIG. 5, an inclined plate 56 for generating a vortex in the jet water flow is provided inside the jet outlet 55.
In the embodiment, four inclined plates 56 are combined at right angles to form a cross shape in plan view, and the water flow from below is changed in the counterclockwise direction indicated by arrow A in FIG. Thus, a counterclockwise vortex is generated while preventing the screw portion 57 of the spray pipe 55a from being loosened, and the water flow generated upward from the jet outlet 55 is rotated by the vortex.
The inclined plate 56 is not always necessary, and the injection pipe 55a may be formed by a simple straight pipe.

An annular air pipe 6 is provided at the bottom of the washing water tank 2 so as to surround the periphery of the jet outlet 55, and three aerations are provided on the upper surface of the annular air pipe 6 so as to be arranged at least in three directions around the jet outlet 55. A nozzle 6a is attached.
In the embodiment, the annular air pipe 6 is formed in a square shape in a plan view, and a total of 12 aeration nozzles 6a are attached to each of the pipe portions constituting the four sides thereof.

Further, as shown in FIG. 1, the aeration nozzles are attached so that the upper end side is inclined at an angle θ in the circumferential direction to generate a vortex in the water flow.
In this case, the inclined direction is parallel to the extending direction of the annular air tube 6 and is substantially counterclockwise about the jet outlet 55 so as to be in the same direction as the vortex direction of the water flow from the jet outlet 55. It is attached so as to generate the eddy current.

If the vortex flow direction of the water flow from the jet nozzle 55 and the vortex flow direction of the bubbles from each aeration nozzle 6a are made the same direction, the force of the vortex flow can be improved and the cleaning effect can be improved, and the water flow from the jet nozzle 55 can be improved. It is also possible to reverse the vortex flow direction and the vortex flow direction of the bubbles from each of the aeration nozzles 6a. In this case, the water flow and the bubbles are turbulent and the cleaning effect can be improved.
The inclination of each aeration nozzle 6a is not always necessary, and it may be attached directly above.

The shape of the annular air tube 6 may be circular in a plan view, and the number of aeration nozzles 6a may be, for example, a total of 12 at intervals of 45 degrees in the circumferential direction. What is necessary is just to have three aeration nozzles so that it may arrange | position to the circumference | surroundings 3 of 55.

The food washing apparatus of the present invention performs washing using a washing basket 9 that is detachably mounted in the washing water tank 2.
The washing basket 9 is formed in a cylindrical basket having an outer diameter so as to be accommodated in the washing water tank 2, and a bottom screen 92 is provided at the bottom of the cylindrical body 90, and at the upper end 95 of the cylindrical body 90. A screen tube portion 93 is provided, and a handle 94 is attached to the upper end of the screen tube portion 93.
In FIG. 3, the illustration of the cleaning basket 9 is omitted.

The cleaning basket 9 is detachably mounted by placing the lower end edge of the cylindrical body 90 on a receiving plate 29 protruding from the inner peripheral surface of the bottom of the cleaning water tank 2. The upper end 95 of the body 90 is formed so as to substantially coincide with the overflow edge 22 of the washing water tank 2.

As a mounting structure for attaching and detaching the cleaning basket 9, in addition to the receiving plate 29, for example, a stopper member (not shown) is attached to the outer peripheral surface of the upper end portion of the cylindrical body portion 90, and this stopper member is attached to the cleaning water tank 2. An appropriate mounting structure such as a structure that is detachably mounted on the upper edge can be adopted.

In addition, the cylindrical trunk | drum 90 of the washing | cleaning basket 9 may be formed with a flat plate, and may be formed with a punching board, a metal net, etc.
The screen tube portion 93 of the embodiment is formed as a comb-shaped screen in which a large number of thin bars are inclined at a predetermined interval. They may be juxtaposed in the direction or formed in a lattice shape.

Further, the screen cylinder portion 93 is not limited to the comb-like screen, and may be formed of a punching plate, a metal mesh, or the like. In this case, the interval between the comb teeth, the hole diameter of the punching holes, the size of the mesh, and the like are appropriately determined according to the type of food to be cleaned.
When the cylindrical body 90 and the screen cylinder 93 are formed of a punching plate or a metal mesh, the cylindrical body 90 and the screen cylinder 93 can be formed of an integral punching plate or a metal mesh.
Further, the bottom screen 92 can also be formed of a punching plate or a wire mesh.
The screen tube portion 93 is not necessarily provided, and may be detachable so that it can be attached or detached as necessary.

Thus, by providing the cleaning basket 9 that is detachably mounted in the cleaning water tank 2, it is possible to clean the object to be cleaned while being accommodated in the cleaning basket 9. For this reason, it is possible to perform the work efficiently by facilitating handling such as the work of loading and unloading the object to be cleaned, and the labor burden on the operator can be reduced.

A water flow blocking plate 92 a is formed at the center of the bottom screen 92.
The shape of the water flow blocking plate 92a is not particularly limited as long as it has a function of blocking the water flow, such as a square, a circle, an ellipse, a rectangle, etc. The size of the water flow blocking plate 92a is such that bubbles are ejected from the aeration nozzle. It is preferable to avoid blocking as much as possible.

Further, a plurality of small water passage holes (not shown) for allowing the water flow to pass through may be formed in the central portion of the water flow blocking plate 92a. A small upward water flow that passes through the water flow blocking plate 92a is generated by the small water flow holes, and the objects to be cleaned gathered in the center of the cleaning water tank 2 by the upward water flow can be dispersed from below. .

In addition to forming the water flow blocking plate 92a at the central portion of the bottom screen 92 of the washing basket 9 as a means for blocking the water flow flowing upward from the jet outlet 55, as shown in FIG. You may make it attach the water flow interruption | blocking board 58 so that the upper direction of the jet nozzle 55 may be interrupted | blocked via the stay 59. FIG.
The injection pipe 55a shown in FIG. 7 is not provided with the inclined plate 56 shown in FIGS.

Therefore, in the food washing apparatus of the present embodiment, the food to be washed is accommodated in the washing basket 9 and submerged in the washing water tank 2 and placed.
Then, the circulating pump 8 is operated to inject the cleaning water in the filtered water tank 7 upward from the outlet 55 of the pressure water pipe 51, and the blower 60 is operated to raise the bubbles upward from the aeration nozzle 6 a of the annular air pipe 6. To erupt.
That is, cleaning can be performed by a combination of a water flow caused by the water jetting upward from the jet outlet 55 of the pressure water pipe 51 and bubbles jetted upward from at least three aeration nozzles 6a around the jet outlet 55. .

In this case, the food to be cleaned is pushed upward in the central portion of the cleaning water tank 2 by the water flow from the water injection port 55 and then sinks around the cleaning water tank 2. The air bubbles are pushed up from the bottom, so the food is beaten by the water flow and the air bubbles, and the inversion is repeated.
Therefore, even a food having a high specific gravity and easily sinks in water can be evenly and uniformly washed, and a sufficient washing effect can be obtained.

In this case, when the operation switch of the circulation pump 8 and the blower 60 is turned on during the cleaning operation, a timer (not shown) that sets the cleaning time is activated at the same time. When the time set by this timer is reached, the circulation pump 8 and the blower 60 are set. The operation switch is turned off, and the cleaning is controlled.

When the cleaning is completed in this way, the cleaning basket 9 is lifted from the cleaning water tank 2, and the internal cleaned food is taken out in a predetermined manner to complete one cleaning cycle.
