Description

The present invention relates to a food washing apparatus used for washing away dust (insects, foreign matter dirt, etc.) adhering 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 cleaning apparatus has been proposed by the applicant of the present application, and is a technology that forms the basis of the present invention, and includes a washing water tank and a filtration water tank, and a circulation pump provided in the filtration water tank and a bottom formed in the washing water tank. A pressure water pipe was connected to the chamber, an injection strainer was attached to the outlet of the pressure water pipe, and an aeration bubble generator was provided in the middle of the pressure water pipe.

This conventional technology is configured so that cleaning water containing bubbles (air-containing water) is jetted upward from the bottom of the cleaning water tank. At this time, aeration and water flow due to the bubbles are uniform over the entire cleaning water tank. In order to disperse the water, an injection strainer was attached to the outlet of the pressure water pipe.

However, when 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 sufficiently obtained, but the injection strainer becomes a resistance and the jet output is weakened. As a result, there remains a problem that the cleaning ability is lowered. In addition, when an injection strainer is attached, there is a problem that it takes time to clean the jet strainer.

In order to solve such a problem, the applicant of the present application uses a structure in which cleaning water containing bubbles (air-containing water) is jetted upward from the bottom of the cleaning water tank, and the aeration and water flow are uniform over the entire cleaning water tank. A food cleaning device has already been proposed that can effectively wash the object to be cleaned from the bottom and spread it up and down so that it is cracked up with sufficient jet power while being dispersed. Japanese Patent Application No. 2010-70381).

This prior art forms a jet opening that opens upward at the tip of the pressure water pipe, while forming a water flow blocking portion in the central portion of the bottom screen of the washing basket and passing the water flow through the central portion of this water flow blocking portion. A plurality of small water passage holes were formed for the purpose.

In this way, a strong jet power can be obtained by opening the jet port upward, and by forming a water flow blocking part, the main flow of the aerated water flowing upward is blocked to generate a radial water flow. Can do.

However, when this 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, so that the objects to be cleaned tend to be insufficiently dispersed.
Therefore, in the prior art, a plurality of small water passage holes for passing the water flow are formed in the central portion of the water flow blocking portion, and a slight upward water flow passing through the water flow blocking portion by the water flow small holes is formed. The objects to be cleaned which are generated and gathered in the center of the cleaning water tank by this upward water flow are dispersed from below.
As a result, 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 is floated up and down so as to be cracked.

However, in the prior art, since only one outlet of the pressure water pipe is provided at the center of the washing water tank in plan view, it is necessary to make the water flow collide with the water flow blocking portion and to disperse, and this collision reduces the water flow momentum. In addition, the problem remains that the water flow is unevenly distributed.

In addition, the water flow hole formed in the water flow blocking portion also has a momentum when passing through the water flow hole because the water flow after being ejected from the outlet of the pressure water pipe is again passed through the water flow hole. The problem still remains, such as a decrease in the flow of water passing through a plurality of small holes.

Japanese Patent No. 4414482

The present invention has been made to solve the above-described problem. In the configuration in which cleaning water (air containing water) containing bubbles is jetted upward from the bottom of the cleaning water tank, the cleaning water (air containing water) is surely provided. In addition, it is possible to perform effective cleaning such that the object to be cleaned is entirely evenly scattered from below and suspended up and down so as to be cracked while being uniformly dispersed throughout the cleaning water tank.

In this way, since at least four upward nozzle tubes (6a) are arranged at equal intervals on the same radius with the center (C) in plan view of the washing water tank (2) as the center, the center in plan view ( Wash water (air-containing water) can be ejected upward at equal intervals (90-degree intervals) on the circumference centered on C).
However, when the four upward nozzle pipes (6a) are sprayed from the circumference centering on the center (C) in plan view, the water flow that collects the objects to be cleaned in the center of the cleaning water tank (2). Therefore, there is a tendency that the object to be cleaned is not sufficiently dispersed.

A plurality of small nozzles (6b) are formed in the vicinity, and the objects to be cleaned gathered at the center of the washing water tank (2) are dispersed from below by the small nozzles (6b). is there.
In addition, since the small nozzle (6b) is provided in the injection nozzle device (6), unlike the above-described prior art, a water flow blocking portion is formed in the central portion of the bottom screen (92) of the cleaning basket (9). This eliminates the need for machining to form a small water passage hole in the central portion of the water flow blocking portion, and facilitates cleaning of the washing basket.

That is, in the present invention, at least four upward nozzle pipes (6a) are arranged at equal intervals in the injection nozzle device (6) connected to the upward tip of the pressure water pipe (51), and the plan view The center (C) and / or a plurality of small jets (6b) are formed in the vicinity of the center (C) in plan view, thereby ensuring the water flow over the entire washing water tank (2). While being uniformly dispersed, it is possible to perform effective cleaning such that the object to be cleaned is entirely evenly crushed from below by a sufficient jet power and floated up and down so as to be cracked.

The food washing apparatus of the present embodiment 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.

The bottom surface of the washing water tank is not limited to the inverted conical bottom surface, and the bottom surface may be formed entirely flat. When the bottom surface of the cleaning water tank 2 is the inverted conical bottom surface 21, the center portion (the bottommost portion) described later is used. ) Bottom chamber 29 is not necessarily required.

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.
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 extended from the circulation pump 8 of the filtered water tank 7 so as to face upward at the center of the bottom surface of the washing water tank 2, and an injection nozzle device 6 is connected to the upward tip of the pressure water pipe 51. Yes.

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.

In this way, the aeration bubble generating device 4 is formed so as to take in air from the air intake port 44 by the momentum of water jetted from the water jet nozzle 45 into the throttle tube 46 and to contain the air. As the drive device, only the circulation pump 8 is required, the structure becomes simple, and it is advantageous in terms of cost, maintenance, compactness, and safety.

The spray nozzle device 6 has a water receiving plate 61 with a circular planar shape formed inside a flat chamber 60 at the upper end of the pressure water pipe 51 and is attached horizontally. A washing water tank is mounted on the upper surface of the water receiving plate 61. Two upward nozzle pipes 6a are arranged at equal intervals (60 degree intervals) on the same radius centered on the center C of the two plan views.
Further, six small jet nozzles 6b formed on the upper surface of the water receiving plate 61 with a diameter smaller than the upward nozzle tube 6a are located in the vicinity of the center C in plan view, which is an inner position of the upward nozzle tube 6a. They are arranged at intervals (60 degree intervals).

Accordingly, the aerated water from the pressure water pipe 51 flows into the flat chamber 60 of the water receiving board 61 and then is jetted upward from the upward nozzle pipe 6a around the inside of the washing water tank 2, and at the same time the central portion in the washing water tank 2 Thus, the water can be ejected upward from the small nozzle 6b, and the water flow can be generated uniformly and uniformly in the washing water tank 2 by the ejection from both the upward nozzle pipe 6a and the small nozzle 6b.

6, 7, and 8 show other examples of the injection nozzle device 6. In the injection nozzle device 6 of FIG. 6, the planar shape of the water receiving plate 61 is formed in a regular hexagon, and each corner thereof is formed. Upward nozzle tubes 6a are respectively attached to the portions, and six small jet nozzles 6b are formed at intervals of 60 degrees in the central portion.

In the spray nozzle device 6 of FIG. 7, the planar shape of the water receiving plate 61 is formed in a regular square, upward nozzle pipes 6 a are respectively attached to the respective corner portions, and one small jet outlet 6 b at the center C in plan view. Is formed. In this case, the small jet nozzle 6b is formed so as to open the pipe body upward, similarly to the upward nozzle pipe 6a.

In the injection nozzle device 6 of FIG. 8, the branch pipe 62 extends from the center in four directions to form a cross-shaped pipe shape, and an upward nozzle pipe 6a is formed at the tip of each branch pipe 62. A small jet nozzle 6b is formed in the central portion with the pipe body opened upward.

The injection nozzle device 6 in FIG. 9 has a structure in which each upward nozzle tube 6a is slightly inclined in the tangential direction (perpendicular to the radial direction) with the upper end side as the center in the plan view C.
As a result, while the object to be cleaned is uniformly dispersed, the object to be cleaned is sprayed from each upward nozzle pipe 6a in addition to the original cleaning effect that the object to be cleaned is swung up and down from the bottom with a sufficient jet power. Since rotation can be applied to the water flow, rotation can be applied to the object to be cleaned, and the cleaning effect can be further improved by the combination of up and down and rotation.

The upward nozzle pipe 6a has a nozzle pipe structure in which the pipe body is opened upward in order to stabilize the directionality of the upward water flow. However, the small jet outlet 6b is simply as shown in FIGS. It may be formed in a hole shape, or may be a nozzle tube structure in which a tube body is opened upward as shown in FIGS.
The number of upward nozzle tubes 6a is at least four, and about four to eight is considered normal.
As for the small jet outlets 6b, one is arranged at the center C in the plan view, about two to eight are arranged at equal intervals around the center C in the plan view, and one at the center C in the plan view. A plurality can be arranged around the periphery.
