Description

The present invention relates to a food washing apparatus used for washing away dust (insects, foreign matter dirt, etc.) attached to food such as vegetables and seaweed.

2. Description of the Related Art Conventionally, a food cleaning apparatus has been proposed in which an object to be cleaned such as vegetables is cleaned in a cleaning water tank (see Patent Document 1).

This conventional food washing apparatus has been proposed by the present applicant and is a technology that forms the basis of the present invention, and includes a washing water tank and a filtration water tank. A pressure water pipe was piped between the chamber and a jet port opening upward at the tip of the pressure water pipe, and an aeration bubble generating device was provided in the middle of the pressure water pipe. An injection strainer was attached to the outlet of the pressure water pipe.
Then, cleaning water containing bubbles (air-containing water) is jetted upward in the cleaning water tank from the jet port formed at the tip of the pressure water pipe, and the object to be cleaned is washed from below.

During this cleaning, dust or the like floating on the surface of the cleaning water overflows the overflow edge together with the cleaning water and flows into the filtered water tank, where it is filtered to remove dust and the like. In order to prevent the washed product from flowing out of the washing water tank, a screen cylinder portion has been conventionally provided at the upper end of the washing water tank.

In addition, by using a cleaning basket that is detachably mounted in the cleaning water tank, it is possible to clean the object to be cleaned while it is stored in the cleaning basket. Therefore, there is an advantage that the work can be performed efficiently and the labor burden on the worker can be reduced.
Even when this washing basket is used, conventionally, a screen cylinder portion is provided at the upper end of the washing basket in order to prevent the washing object from flowing out.

Thus, if the screen cylinder part is provided at the upper end of the cleaning water tank or the upper end of the cleaning basket, the outflow of the object to be cleaned can be prevented, but the manufacturing cost is increased by the provision of this screen cylinder part, and the cleaning is troublesome. Such a problem arises.

By the way, as described above, a cleaning method for cleaning an object to be cleaned from below by injecting cleaning water containing air bubbles (air-containing water) upwards in the cleaning water tank from the outlet formed at the tip of the pressure water pipe. In the case where the object to be cleaned is a food having a small specific gravity such as leafy vegetables such as cabbage or lettuce, in order to prevent the object to be cleaned from flowing out of the cleaning water tank as in the past, It was necessary to provide a screen cylinder.
On the other hand, in the case of foods with a high specific gravity such as garlic, salted cucumber, potato, ginger, small meat pieces, cut radish, cut carrots, etc., the object to be cleaned will not flow out. It is not necessary to provide the screen cylinder portion, and the screen tube portion can be omitted.

Japanese Patent No. 4414482

The present applicant has already proposed the invention relating to the water flow blocking portion (92a) in claim 3 above, the water flow blocking portion (92a) and the water passage small hole (92b) in claim 4 prior to the present application. However, these prior applications employ a configuration in which a screen cylinder is provided at the upper end of the cleaning basket. It differs from the invention in its configuration and is not the same invention.

The food washing apparatus of the present invention (Claims 1 to 8) includes a washing water tank and a filtration water tank, and a pressure water pipe is provided between a circulation pump provided in the filtration water tank and a bottom chamber formed in the washing water tank. An aeration bubble generator is installed in the middle of the water pipe, and cleaning water containing air bubbles (air-containing water) is jetted upward in the washing water tank from the spout formed at the tip of the pressure water pipe. The basic structure is a structure that is washed and washed.

In addition, as a configuration that includes a washing basket that is detachably mounted in the washing water tank, and that corresponds to the fact that food having a high specific gravity is used as an object to be washed, the conventional screen cylinder is omitted, and the upper edge of the washing basket is It is characterized by the point formed at the outflow edge.

Thus, since the washing basket which is detachably mounted in the washing water tank is provided, it is possible to wash the object to be washed such as vegetables in the washing basket. 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.

In particular, unlike the conventional case, there is no screen cylinder at the upper end of the washing basket, and the upper edge of the washing basket is formed at the water outflow edge.
Thus, since the screen cylinder part conventionally required is omitted, it is possible to reduce the manufacturing cost and the labor for cleaning.

Further, in the food cleaning apparatus of the present invention, the dust and the like that float on the surface of the cleaning water along with the cleaning is formed on the water outflow edge formed on the upper edge of the cleaning basket together with the cleaning water and the upper edge of the cleaning tank The overflow edge overflows and flows into the filtered water tank, where it is filtered to remove dust and the like.
As described above, by providing the water outflow edge and the overflow edge, it is possible to introduce the cleaning water containing dust and the like into the filtered water tank and reliably filter it.

Further, since the aeration bubble generating device is provided in the middle of the pressure water pipe, it is not necessary to separately provide the air blowing device and the water supply device, which is advantageous in terms of cost, maintenance, and compactness.
Further, since the aeration blower constituting the air jetting device is not required, energy saving is achieved, and deterioration of the work environment due to noise can be eliminated.

Further, with the formation of the bottom surface of the cleaning water tank to the reverse conical bottom, the inside provided with the base-portion room for the central portion of the reverse pyramid shaped bottom surface, the pressure water pipe tip is open upward spout (51) (55) Therefore, the inverted conical bottom surface functions as a guide for water flow, and the scattering direction of the aerated water can be stabilized. Thereby, scattering of the aerated water in irregular directions can be prevented, and the aerated water can be effectively bathed in the food to be cleaned.

Moreover, since the food strainer of the present invention (Claim 1) is equipped with an injection strainer at the outlet of the pressure water pipe, it is possible to uniformly disperse the aerated water over the entire washing water tank. Can be washed well.

The food washing apparatus of the present invention (Claim 2) does not have an injection strainer attached to the outlet of the pressure water pipe.
If an injection strainer is attached to the outlet of the pressure water pipe, the effect of uniformly dispersing the aerated water over the entire washing water tank can be obtained, but the jet strainer becomes a resistance and the jet output is weakened. Ability tends to decline.
In order to cope with this, the present invention (Claim 2) is one in which the jet outlet is opened upward without attaching the jet strainer, whereby a strong jet power can be obtained and the cleaning ability can be improved.

Next, in the food washing apparatus of the present invention (Claim 3), the water flow blocking portion is formed at the central portion of the bottom screen of the washing basket after opening the outlet of the pressure water pipe upward.
As described above, a strong jet power can be obtained by forming a jet port that opens upward at the tip of the pressure water pipe without using a jet strainer that provides resistance to jet power.

However, if a jet port that opens upward is formed at the tip of the pressure water pipe, the main flow of the aerated water is generated upward, making it difficult to uniformly disperse the aerated water over the entire washing water tank.
Therefore, a water flow blocking portion is formed at the central portion of the bottom screen of the washing basket, and the main flow of the aerated water flowing upward is blocked by the water flow blocking portion, thereby generating a radial water flow. Air bubbles and water flow can be uniformly dispersed throughout the washing water tank.

In this way, forming a jet port that opens upward to obtain a strong jet power, forming a water flow blocking portion, and uniformly dispersing bubbles and water flow from the aerated water over the entire washing water tank, With this combination, it is possible to perform effective cleaning even for food to be cleaned having a high specific gravity.

Next, the food washing apparatus of the present invention (Claim 4) forms an upwardly opening jet at the tip of the pressure water pipe, and forms a water flow blocking part at the center of the bottom screen of the washing basket. There is a feature in a configuration in which a plurality of small water passage holes for allowing a water flow to pass through are formed in the central portion of the blocking portion.

When the water flow blocking portion is formed, a water flow is generated above the water flow blocking portion so that the objects to be cleaned are gathered in the center of the cleaning water tank, and thus there is a tendency that the objects to be cleaned are not sufficiently dispersed.

Therefore, in the present invention (Claim 4), a plurality of small water passage holes are formed in the central portion of the water flow blocking portion to allow the water flow to pass therethrough. An upward water flow is generated, and the objects to be cleaned gathered in the center of the cleaning water tank by this upward water flow are dispersed from below.

Therefore, according to the present invention (Claim 4), it is possible to perform effective cleaning such that the object to be cleaned is entirely evenly crushed from below with a sufficient jet power and floated up and down so as to be cracked.

Further, if the overflow edge is formed over the entire upper edge of the washing water tank (Claim 5), it can overflow from anywhere in the washing water tank, and the washing water containing dust etc. stays without overflowing. There is no such thing.
Moreover, since the opening width of the water collecting port is formed wider than the diameter of the washing water tank (Claim 5),
The water collection area can be increased, and the flow of cleaning water containing dust and the like can be made smooth to reliably flow into the filtered water tank.

Further, if the cleaning water containing dust introduced from the bottom chamber is also formed to flow into the filtered water tank (Claim 6), the dust floating in the water passes through the bottom screen of the cleaning basket together with the cleaning water. It can be made to flow into the filtered water tank from the bottom chamber, where it can be filtered to remove dust and the like.
In this way, the washing water overflowing the water outflow edge of the washing basket and the overflow edge of the washing tank, and the washing water from the bottom chamber flow into the filtration water tank and are filtered here, so that the washing water is surely filtered. Can do.

Further, when the aeration bubble generating device is formed so as to take in air from the air intake port by the force of water jetted from the water jet nozzle toward the inside of the throttle tube, it is used as a drive device. Is only a circulation pump, which simplifies its structure and is advantageous in terms of cost, maintenance, compactness, and safety.

Further, if an inclined plate is provided inside the jet outlet formed at the tip of the pressure water pipe (Claim 8), the water flow generated upward from the jet outlet can be rotated by a vortex, and the upward water flow and the rotary water flow Thus, the object to be cleaned can be dispersed from multiple directions, and the cleaning effect can be further improved.

The food washing apparatus according to the first embodiment corresponds to claim 4 of the present invention, and includes a washing water tank 2 and a filtered water tank 7 assembled to the machine casing 1.

The washing water tank 2 is formed in a circular container having an upper surface opened and a bottom surface formed in an inverted conical bottom surface (inverted conical bottom surface) 21.
The cleaning water tank 2 of the embodiment is formed in a circular container formed on an inverted conical bottom surface whose bottom surface is gradually reduced toward the center, but is not limited thereto, and may be formed in a rectangular container. The inverted conical bottom surface 21 is formed to have a quadrangular periphery and gradually become a circle toward the center.

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 constant width is formed on the half-circumferential portion of the washing water tank 2, and the other half-circumferential portion of the washing 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.
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 inside of the filtered water tank 7. Flow into.
In FIG. 2, the filtered water tank 7 is not shown, and the cleaning basket 9 is not shown in FIG.

A bottom chamber 29 is formed at the center (bottommost portion) of the inverted conical bottom surface 21 of the washing water tank 2, and a lower inflow pipe 34 is connected between the bottom chamber 29 and the bottom of the bowl-shaped channel 24. The lower inflow pipe 34 allows dust and the like floating in the water to flow into the filtered water tank 7 from the bottom chamber 29 together with the cleaning water, and is filtered here to remove the dust and the like.
The lower inflow pipe 34 is not necessarily provided, and is appropriately determined in consideration of the type of the object to be cleaned, cleaning conditions, and the like.
In the figure, reference numeral 35 denotes a drain drain valve for a washing water tank.

The filtration water tank 7 is made to flow by flowing washing water containing dust and the like overflowing from the overflow edge 22 of the washing water tank 2 and washing water containing dust and the like introduced by the lower inflow pipe 34. It is formed in a 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.
In the figure, reference numeral 70 denotes a drain drain valve for a filtered water tank.

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.

A pressure water pipe 51 is piped between the circulation pump 8 and the bottom chamber 29 located at the center of the washing water tank 2, and an injection pipe 55 a 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 FIGS. 5, 6, and 7, 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 number of the inclined plates 56 is considered to be appropriate from about 2 to 6, but if it is too large, it will be a resistance to weaken the water flow, and if it is too small, the effect of changing the direction of the water flow will be small. And the tilt angle is set.

An aeration foam generator 4 is attached in the middle of the pressure water pipe 51.
The aeration foam generator 4 is configured such that the upstream disk 42 and the downstream disk 43 are opposed to each other via several collars 41 arranged at equal intervals in the circumferential direction, so that both the disks 42 are connected. , 43 is opened to the outer periphery to hold the air intake port 44, the water injection nozzle 45 is attached to the upstream disk 42, and the throttle tube 46 formed by a reducer is attached to the downstream disk 43. It has become. In this case, the water level W in the washing water tank 2 is installed so as to substantially coincide with the throttle portion (small diameter portion) of the throttle pipe 46.

Then, the cleaning water pumped by the circulation pump 8 is jetted from the water jet nozzle 45 into the throttle pipe 46, so that the air is taken in from the air intake port 44 by the attracting action of the washing water. It is formed so that bubbles are included in water.
The momentum from the water jet nozzle 45 and the degree of restriction of the throttle pipe 46 are set as appropriate. In particular, if the throttle pipe 46 is excessively throttled, the washing water flows backward and overflows from the air intake port 44. However, when the aperture is small and close to straight, the bubbles become large, which is not suitable for cleaning aeration.

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 circular basket having an outer diameter so as to be accommodated in the washing water tank 2, and the bottom of the cylindrical body 90 is formed on the bottom screen 92, and the cylinder serving as the upper edge of the washing basket 9. An upper end edge 95 of the cylindrical body 90 is formed as a water outflow edge, and a handle 94 is attached to the upper end edge 95.

A stopper member 96 is attached to the outer peripheral surface of the cylindrical body portion 90 of the cleaning basket 9 and is detachably mounted by locking the stopper member 96 to the upper edge of the cleaning water tank 2. The upper edge 95 of the cleaning basket 9 is formed so as to substantially coincide with the overflow edge 22 of the cleaning water tank 2.

The cylindrical body portion 90 of the cleaning basket 9 may be formed of a flat plate, a punching plate, a mesh plate, or the like.
Further, the bottom screen 92 is not limited to the through-hole screen in which a large number of punching holes 97 are formed as in the embodiment, but can be formed by a mesh screen 97a, a wire net, or the like as shown in FIGS.

A water flow blocking portion 92a is formed in the central portion of the bottom screen 92, and a plurality of small water passage holes 92b are formed in the central portion of the water flow blocking portion 92a.

In the embodiment, the shape of the water flow blocking portion 92a is formed in a rectangular shape, but the shape is not particularly limited as long as the water flow blocking portion 92a has a function of blocking water flow, such as a square, a circle, and an ellipse. .

The small water passage holes 92b are formed at the center of the water flow blocking portion 92a, that is, almost directly above the jet outlet 55. In the embodiment, the six small water passage holes 92b are formed every 60 degrees. Are formed at equal intervals, but two water passage holes are made every 180 degrees, three water passage holes are every 120 degrees, four water passage holes are every 90 degrees, and five passage holes are made. Up to about 8 seems to be appropriate, such as forming water holes at regular intervals of 72 degrees.

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, the bubbles are aerated by the aeration bubble generator 4 provided in the middle while the washing water in the filtered water tank 7 is pumped by the pressure water pipe 51, and the aerated water is washed into the washing water tank 2. It is made to inject upward from the jet outlet 55 provided in the bottom chamber 29.

In the first embodiment, since the jet outlet 55 is opened upward, a strong jet output can be obtained, and since the water flow blocking portion 92a is formed on the bottom screen 92 of the washing basket 9, the upward flow is included. The main flow of air can be blocked to generate a radial water flow.

Furthermore, since a plurality of small water passage holes 92b for allowing the water flow to pass therethrough are formed in the central portion of the water flow blocking portion 92a, a slight upward water flow passing through the water flow blocking portion 92a is caused by the small water passage holes 92b. The objects to be cleaned that are generated and gathered in the center of the cleaning water tank 2 by this upward water flow can be dispersed from below.

Thereby, it is possible to perform effective cleaning such that the object to be cleaned is entirely evenly crushed from below and floated up and down so as to be cracked while obtaining a sufficient jet power.

Further, since the inclined plate 56 is provided inside the jet outlet 55, the water flow generated upward from the jet outlet 55 can be rotated by a vortex, and the object to be cleaned can be moved from multiple directions by the upward water flow and the rotary water flow. Thus, it can be dispersed and the cleaning effect can be further improved.
The inclined plate 56 is not always necessary.

In addition, the dust that floats on the surface of the cleaning water along with the cleaning, and the dust that floats in the water flow into the filtered water tank 7 together with the cleaning water. Inflow and dust etc. are removed.
The filtered washing water in the filtered water tank 7 is pumped to the pressure water pipe 51 by the circulation pump 8 and sprayed into the washing water tank 2 from the ejection port 55, and the food can be washed by repeating this. .

In this case, when the operation switch of the circulation pump 8 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 operation switch of the circulation pump 8 is turned off, It is controlled so that the cleaning is completed.
In FIG. 1, reference numeral 15 denotes a control box.

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.

Next, the food washing apparatus of Example 2 shown in FIG. 8 corresponds to claim 3 of the present invention.
This food washing apparatus is formed with an upwardly opening spout 55 and a water flow blocking part 92a formed at the central portion of the bottom screen 92 of the washing basket. Unlike the food washing apparatus of Example 1, In this embodiment, a plurality of small water passage holes 92b are not formed in the central portion of the water flow blocking portion 92a.

As described above, even when the small water passage hole 92b is not formed, the jet port 55 opened upward is formed to obtain a strong jet power, and the water flow blocking portion 92a is formed to contain the aerated water. By combining the air bubbles and the water flow uniformly distributed over the entire washing water tank 2, it is possible to effectively wash the food to be washed having a high specific gravity.

Next, the food washing apparatus of Example 3 shown in FIG. 9 corresponds to claim 2 of the present invention.
This food cleaning apparatus is formed with an upwardly opening jet outlet 55, and unlike the food cleaning apparatus of the first embodiment, the water flow blocking section 92 a is not formed in the central portion of the bottom screen 92 of the cleaning basket. It is an aspect.

As described above, even when the water flow blocking portion 92a is not formed, the cleaning ability can be improved by forming the jet port 55 opened upward to obtain a strong jet power.

Next, the food washing apparatus of Example 4 shown in FIG. 10 corresponds to claim 1 of the present invention.
This food washing apparatus is a mode in which the jet strainer 6 is attached to the jet outlet 55 opened at the tip of the pressure water pipe 51.
