Further, the air nozzle 7b protruding from the vertical pipes 73 and 73 is slightly inclined forward (approximately 5 to 10 degrees forward from the vertical) so as to face the flow direction of the water flow.

In order to use the food washing apparatus 1 of this embodiment, first, the washing water is stored in the washing chamber 20 in a full tank state, and the washing water does not overflow from the overflow port 3a into the filtered water tank 3. Store.
Then, in a state where the support pins 57 of the food storage bucket 5 are fitted into the locking holes 25 of the bracket 24, the food storage bucket 5 is mounted in the cleaning chamber 20, and the cut vegetables as the food to be cleaned are put in and stored therein. .

Next, the circulation pump P and the blower 6 are operated, and the operation of the circulation pump P causes the cleaning water in the filtered water tank 3 to flow into the cleaning chamber 20 through the water supply pipe 34 and the cleaning water in the cleaning chamber 20. Is returned to the filtered water tank 3 through the drain pipe 30 and the washing water overflowing from the upper left edge 21 and the upper back edge 22 of the washing chamber 20 is collected by the collecting section 23 and then filtered through the collecting pipe 38. The washing water is circulated back to the inside.
At the same time, by the operation of the blower 6, bubbles are jetted upward from the air nozzles 7a, 7b of the air ejection pipe 7 into the cleaning chamber 20, and the upward bubbles cause a vertical flow in the cleaning chamber 20. Then, the cut vegetables can be beaten in the food storage bucket 5 and floated up and down so as to be broken.

Thus, while the cut vegetables are being washed in the food storage bucket 5, the wash water is circulated between the washing chamber 20 and the filtered water tank 3, so that floating dust generated by washing (particularly, Insects, hair, warax and food waste) flow into the filtered water tank 3 along with the washing water through the drain pipe 30 and flow into the filtered water tank 3 through the collecting pipe 38 from the recovery unit 23 together with the overflowed washing water.
At this time, since the filtering bag-like meshes 40, 40 are attached to the outlet 32 of the drain pipe 30 and the recovery outlet 39 of the collecting pipe 38, insects and foreign matters are contaminated in the filtering bag-like mesh 40, 40.

It should be noted that dust having a large specific gravity, such as mud produced by washing, sinks in the washing chamber 20 and enters the mud container 28 through the through hole 29 of the partition wall 27, and no washing water flows here. It is possible to prevent the minute from flying up in the cleaning chamber 20.

In addition, when the water supply ports 35 and 35 of the water supply pipe 34 are branched to the left and right so as to face the left and right side surfaces of the cleaning chamber 20, the water flow from the water supply ports 35 and 35 (arrow M in FIG. 4) is washed. The flow of colliding with the left and right side surfaces of the chamber 20 and returning to the inside can be generated.
Further, if the inlets 31, 31 of the drain pipe 30 are formed to branch left and right so as to face the left and right side surfaces of the cleaning chamber 20, the cleaning water flows into the drain pipe 30 from the left and right side portions of the cleaning chamber 20. Can be generated (arrow N in FIG. 5).
By such a water flow, a flow in the left-right direction is added to the flow in the cleaning chamber 20, and the cleaning effect can be improved.

Further, when the water flow guide plate 58 is provided on the outer surface of the back mesh portion 51 of the food storage bucket 5, a part of the water flow that passes through the back mesh portion 51 and flows out of the bucket to the outside of the bucket is supplied to the water flow guide plate 58. It can be applied to the inner surface of the bucket, raised along the inclination, and returned to the inside of the bucket again.
In the cleaning chamber 20, since the cleaning water flows from the front (left side in FIG. 1) to the back (right side in FIG. 1) as a whole, the cut vegetables stay on the back net 51 of the food storage bucket 5. There are things to do.
On the other hand, when the water flow is generated from the outside of the bucket to the inside of the bucket by the water flow guide plate 58 as described above, the cut vegetables attached to the back net portion 51 can be peeled off, and the washing of the cut vegetables is promoted. The effect can be improved.

Further, in the air ejection pipe 7, the air nozzle 7 a is erected substantially vertically so as to raise bubbles along the front mesh part 50 and the rear mesh part 51 of the food storage bucket 5 mounted in the cleaning chamber 20. Therefore, it is possible to expose the cut vegetables staying in a state of being stuck to the front mesh portion 50 and the back mesh portion 51 of the food containing bucket 5 from below, and to peel off the stuck cut vegetables.
Further, since the air nozzle 7b is inclined and protruded slightly forward so as to face the flow direction of the water flow, the water flow and the bubbles collide with each other, and the flow in the cleaning chamber 20 is caused to flow in the front-rear direction. Flow is added and the cleaning effect can be improved.

  Thus, in the food cleaning apparatus 1 of the present embodiment, the cleaning water is stirred up and down, left and right, and back and forth in the cleaning chamber 20, and the food to be cleaned (cut vegetables) in the food storage bucket 5 is randomly floated. Therefore, effective cleaning can be performed.

In the present invention, it is preferable to prepare several types of mesh sizes of the food storage buckets corresponding to the size of the food to be cleaned (for example, the difference between the vegetable hole and the scraped product). .
Moreover, in this invention, the thing of the shape as it is, such as leafy vegetables, root vegetables, seaweed, etc., and what was cut-processed or knurled, etc. can be used as food for washing | cleaning.
