DESCRIPTION OF RELATED ART Conventionally, the food washing apparatus which accommodates foods to wash | cleans, such as vegetables, in a dehydration basket (accommodating bucket) and wash | cleans in a washing water tank is known (refer patent document 1).
This food washing apparatus is equipped with a dewatering basket that can be inserted and removed inside and outside the washing water tank, and an air jet pipe is provided at the bottom of the washing water tank, and air is jetted upward from the air jet pipe. Thus, the food to be cleaned in the dehydrated basket is squeezed and washed while floating up and down so as to be broken.

JP 2005-341925 A

However, in the conventional food washing apparatus, the dehydration basket is attached so that it can be taken in and out of the inside of the washing water tank, so that there is a problem that the labor burden on the operator becomes large when the dehydration basket is taken in and out. It was.
In addition, since the air ejection pipe is fixed to the bottom of the washing water tank, when cleaning the bottom of the washing water tank, the air ejection pipe gets in the way and the corners are inaccessible and cannot be cleaned sufficiently. The problem was left.
Further, since the air ejection pipe is disposed outside the dehydration basket, that is, below the bottom of the dehydration basket, the momentum is killed when the air (bubbles) ejected from the air ejection pipe passes through the dehydration basket. As a result, there is a problem that the cleaning efficiency is lowered.

  The present invention does not allow the dewatering basket to be taken in and out of the inside and outside of the washing water tank, but raises and lowers the dewatering basket inside the washing water tank, thereby reducing the labor burden on the operator and water generated by the water jet nozzle. By making the spray inside the dewatered basket, it is possible to prevent the presence of the dehydrated basket from interfering with the spray and to efficiently wash, while further preventing the food from flowing out (escape) from the dehydrated basket An object of the present invention is to provide a food washing apparatus capable of reliably filtering washing water.

In order to solve the above problems, the food washing apparatus of the present invention is:
A washing water tank (2) for containing washing water therein;
A dewatering basket (3) that is movable up and down between the lowered position and the raised position and is detachably attached to the inside of the washing water tank,
A set position that continues to the upper surface opening of the washing water tank and presses the dewatering basket from above and holds it in the lowered position, and moves away from the upper surface opening of the washing water tank and releases the dewatering basket to the raised position. An upper cleaning cylinder (4) formed so as to be able to move up and down,
An overflow screen opening (41) opened in the body wall of the upper cleaning cylinder;
A water injection nozzle (6) attached to the upper cleaning cylinder and moving up and down between an underwater immersion position in the dehydration basket and a lifting position outside the dehydration basket in accordance with the lifting operation of the upper cleaning cylinder;
A filtered water tank (7) into which cleaning water containing dust overflowed from the screen opening of the upper cleaning cylinder flows,
The circulation water pump (8) for pumping the washing water from the filtered water tank to the water injection nozzle is provided.

  In the food washing apparatus of the present invention (Claim 1), the dewatered basket can be moved up and down between the lowered position and the raised position inside the washing water tank, and the food is stored in the dehydrated basket at the raised position. Moreover, since the food after washing can be taken out at the raised position, it is possible to work efficiently while preventing the food from escaping from the dehydrated basket and escaping, and the labor load of the operator is reduced. Can be reduced.

  Further, when washing, the dehydration basket is submerged to the lowered position. At this time, the upper washing cylinder is lowered from the separation position to the set position, and the upper washing cylinder is continuously connected to the upper surface opening of the washing water tank and the dehydration basket is placed. Hold the basket from above and hold it in the lowered position.

In this state, since the washing water tank is extended upward by the upper washing cylinder, it is possible to prevent the food from flowing out from the upper washing cylinder and escaping during washing.
In addition, dust that floats on the surface of the cleaning water accompanying the cleaning overflows with the cleaning water from the screen opening of the upper cleaning cylinder and flows into the filtered water tank, where it is filtered to remove the dust and the like. .
Thus, by providing the upper cleaning cylinder, it is possible to prevent the outflow (escape) of food even during cleaning, and it is possible to introduce cleaning water including dust etc. into the filtered water tank and reliably filter it. it can.

Further, when cleaning, the water injection nozzle descends from the lifting position outside the dewatering basket to the underwater immersion position in the dewatering basket as the upper cleaning cylinder descends, and the cleaning water in the filtered water tank is pumped and sprayed by the circulation pump. .
The food is washed while the water flow is generated in the washing water in the washing water tank by the momentum generated by the washing water.

  At this time, since the water injection nozzle is located inside the dehydration basket, water can be injected inside the dehydration basket. Unlike the conventional technique in which bubbles are injected from the outside of the dehydration basket, the presence of the dehydration basket exists. There is no hindrance to the injection, and the cleaning with the water injection nozzle can be performed efficiently.

In addition, an air intake (not shown) is formed at the upper end of the water injection nozzle 6, and the cleaning water ejected from the water injection nozzle 6 contains some bubbles to improve the cleaning effect.

The filtered water tank 7 is used to allow cleaning water containing dust and the like overflowing from the screen openings 41 and 41 of the upper cleaning cylinder 4 to flow and be filtered, and is formed in a rectangular container.
The filtered water tank 7 is disposed below a bag mounting plate 23 provided at the front end of the recovery tank 22, and a submersible pump as a circulation pump 8 is installed in the filtered water tank 7. Wash water is pumped to the water jet nozzle 6 via a water supply hose 81.
Further, the filtered water tank 7 is always supplied with water from the water supply port 71 during the cleaning operation, and the dirty cleaning water is discharged from the overflow hole 72.
In FIG. 1, reference numeral 73 denotes a drain drain valve.

A filtration mesh bag 9 is detachably attached to the bag attaching plate 23.
The filtration mesh bag 9 is formed of a mesh made of cotton, hemp, or a synthetic resin material, and is attached so as to be detachable by covering the bag mounting plate 23 with the mouth portion tied.

Therefore, in the food washing apparatus A of the present embodiment, the food to be washed is accommodated in the dewatering basket 3 held at the raised position by the spring 33 of the lifting device 30 and then the upper portion is washed by the link mechanism 5. The cylinder 4 is lowered from the separation position to the set position.
At this time, while holding the upper edge of the dewatering basket 3 from above with the flange plate 40 of the upper washing cylinder 4, the dewatering basket 3 is submerged against the spring 33, and the flange plate 40 is placed on the flange surface 20 of the washing water tank. By placing the upper cleaning cylinder 4 on the upper surface opening of the cleaning water tank 2, the upper cleaning cylinder 4 is made continuous. Thereby, it can prevent that a foodstuff flows out from the dehydration basket 3 and escapes.
The upper cleaning cylinder 4 is held at the set position by a lock claw 56 attached to the swing arm 50 of the link mechanism 5.

As the upper cleaning cylinder 4 is lowered to the set position, the water injection nozzle 6 is lowered from the lifted position to the underwater immersion position.
Then, the circulating pump 8 is operated, and the cleaning water in the filtered water tank 7 is pumped and sprayed to the water injection nozzle 6 via the water supply hose 81. The food is washed while generating a water flow in the washing water.

The direction of the water flow in this case is shown in FIGS.
The washing water jetted from the jet hole group 61 formed in the water jet nozzle 6 is jetted radially in multiple directions around the water jet nozzle 6, and the multidirectional water flow such as the water flow reflected by the dehydration basket 3 or the spiral water flow. In particular, in the vicinity of the water surface, a water flow is generated along the inner surface of the upper cleaning cylinder 4 toward the screen opening 41. Therefore, the cleaning water containing dust or the like is efficiently overflowed from the screen opening 41 on this water flow. Can be made.

Moreover, since the washing water sprayed from the lower side horizontal jet port 62 becomes a water flow along the peripheral wall of the dewatering basket 3 to generate a spiral water flow, and the washing water tank 2 is formed in an inverted truncated cone shape, There will also be a convective water flow in the direction.
The water flow from these injection hole groups 61 and the horizontal injection holes 62 rotates the food as a whole in the dewatering basket 3 and repeats ups and downs in the vertical direction. It can be bathed and stirred, and the cleaning effect can be improved.

Further, since the water injection nozzle 6 is disposed inside the dehydration basket 3, water can be injected inside the dehydration basket 3, and the presence of the dehydration basket 3 does not hinder the injection, and the water injection Cleaning with the nozzle 6 can be performed efficiently.

The cleaning water overflowed from the screen opening 41 of the upper cleaning cylinder 4 flows out into the flange surface 20 of the cleaning water tank 2 and then flows into the filtration mesh bag 9 from the discharge hole 24 through the recovery hole 25 from the inlet hole 21. At the same time, it also flows into the filtration mesh bag 9 from the collection tank 22, and after filtering and removing dust etc. with this filtration mesh bag 9, it flows into the filtered water tank 7.
The filtered washing water in the filtered water tank 7 is again pumped and injected by the circulation pump 8 to the water injection nozzle 6 through the water supply hose 81, and adheres to the food while washing the food while repeating this. It will remove dust.

  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 and the cleaning is performed. Is controlled to end.

When the cleaning operation is thus completed, the lock claw 56 is released, the swing arm 50 is lifted, and the upper cleaning cylinder 4 is raised from the set position to the separated position.
Accordingly, the water injection nozzle 6 also rises from the underwater immersion position to the lifting position.

Furthermore, since the dehydration basket 3 is also automatically raised from the lowered position to the raised position by the spring 33 of the lifting device 30, it is possible to prevent the food from flowing out from the dehydrated basket 3 and escaping.
Further, after the washing, the dehydrated basket 3 is lifted by the bias of the spring 33, so that the dehydrated basket 3 can be pulled up without touching the water, and the washed food can be easily taken out in the raised state. it can.

  In the present invention, since the dehydrated basket 3 is detachably attached, it is possible to remove the dehydrated basket 3 and directly store the food in the washing water tank 2 for cleaning. It can be removed and used as a sink.
