Abstract

PROBLEM TO BE SOLVED: To provide a cleaning apparatus which separates vegetables from dust attached thereto without fail by placing a coarse net 30. SOLUTION: A groove-shape guide 31 is attached to each of both the inside wall surfaces of a water tank 10, and the coarse net 30 slides along these guides 31 and can move up and down. A pair of wires 32 joined to the upper edge of the frame of the net 30 are joined, via pulleys 33, to a reel 35 attached to a frame 34, and the reel 35 is rotated normally or inversely by a motor 36 installed at the frame 34. By rotating the reel in one direction, the net 30 shuts up the inside of the water tank 10 by borrowing the weight of a weight block 37, forming an isolation chamber 38. Vegetables contained in the isolation chamber 38 are subjected to agitation by a jet water stream 11 jetted in the direction of arrows, and only dust separated from the surfaces of the vegetables is caused to pass 43 through the net 30 to be recovered. After a certain time elapses, the net 30 is opened and the cleaned vegetables are carried by the jet stream 11 and taken out.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water-rinsing apparatus for mainly cleaning food materials. It should be noted that the term “water” described in this specification refers to the whole liquid suitable for cleaning in a broader concept, which is sometimes slightly heated.

[0002]

2. Description of the Related Art As shown in FIG. 2, this type of known automatic cleaning apparatus basically has a water tank 10 having an upper surface and having a slightly elongated shape. At one end 15 of the water tank, a jet water stream is blown from the outside of the tank toward the inside of the tank as indicated by an arrow 11, while compressed air blown from the peripheral surface of the laying pipe 12 is discharged from countless small holes formed in the tank bottom surface 13. To form bubbles 14. Then, when an appropriate number of vegetables are put into the water tank at one end 15 of the water tank 10, each of these vegetables is rotated by the jet water stream 11, and the breaking water pressure of the jet water stream 11 and the breaking pressure of each bubble 14 are respectively increased. It is configured to move in the direction of arrow 11 while washing off dust and dirt attached to the surface by the impact, and finally remove it to the outside of the tank by the carry-out conveyor 17 at the other end 16 of the water tank. On the other hand, as shown in FIG. 3, the rotary shafts 18 and 19 installed between the side walls of the water tank rotate a number of vanes 20 formed along the axis thereof, and suck the dust floating on the water surface into the hollow shaft 20. From the hole 22, the water is discharged off-axis integrally with the water.

[0003] Food materials used for washing are mainly vegetables, such as small bulbs like raccoon and large ones such as Chinese cabbage and radish. The soil that adheres to these vegetables is washed off and distributed locally, so it is rarely used for cleaning soil and sand, but is often used to remove pits or lint between vegetables and leaves. . In recent years, this type of washing device is frequently used for desalting pickled vegetables for pickles imported from foreign countries.However, imported vegetables have a higher adhesion rate of hair, insects, wood chips, and lint than domestic vegetables.
Since the removal of these dusts is not reliable in this type of conventional apparatus, there is a problem in that it is necessary to resort to manual dust removal after all.

[0004]

[MEANS FOR SOLVING PROBLEMS] The present invention injects a jet water stream toward stored water stored up to a set level in a water tank for the purpose of making the dust removal cleaning more complete and efficient, and over-flows the surplus water amount. While forming a flow in a certain direction while generating countless bubbles from the bottom of the water tank, the jet pressure impact, and the destructive impact of the bubbles, while washing the object to be washed in the storage water, In a washing machine for moving the object to be washed toward an unloading conveyor installed downstream of the flow, a coarse net is disposed in the water tank so as to be openable and closable, and the coarse net is sunk so as to partition the inside of the water tank. In the chamber, means for temporarily stopping and cleaning the object to be cleaned is provided.

[0005] In the above construction, since the coarse net is submerged in the water tank to form an isolation chamber partitioned by the coarse net, the object to be cleaned is inevitably stopped in the isolation chamber and stopped for a predetermined time. Because it is washed, the effect of dust removal increases. The coarse net refers to a mesh value through which the object to be washed does not pass but dust can pass.During the washing, dust peeling from the object to be washed passes through the net and overflows outside the tank downstream. . Thereafter, when the net is opened, the washed material flows in the downstream direction along the water flow, and is automatically removed from the tank by the carry-out conveyor. Note that the “net” described in the specification is, of course, a net, of course, but a net analog having the same effect, such as “sunoko”, is claimed as a net.

According to a second aspect of the present invention, the fine net is installed in the washing machine so that the carry-out conveyor transfer area can be opened and closed from above the stored water. In the case of this device, dust that flows together with the stored water is hooked on a fine net and removed to prevent the dust from adhering to the carry-out conveyor. Transfer can be prevented.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention is provided with a means for opening and closing a coarse net 30 in the water tank 10 shown in FIG. As shown in FIGS. 1 and 4, the means installs a groove-shaped guide 31 on each of the inner walls of the water tank 10,
The coarse net 30 can move up and down by sliding these two guides 31. The pair of wires 32 connected to the upper edge of the frame of the net 30 are engaged with the reels 35 installed on the frame 34 via the pulleys 33, so that the motor 35 installed on the frame 34 rotates the reel 35 forward and backward. As a result, the coarse net 3 is rotated in one direction.
Numeral 0 closes the inside of the water tank 10 by borrowing the load of the weight block 37 to form an isolation chamber 38 having a predetermined volume.

As shown in FIG. 5, the air pipes 40 on both sides of the water tank 10 are provided with a number of free nozzles 41, respectively. However, since it is set slightly upward, downward, further forward, rearward, and disorderly, complicated turbulence occurs in the stored water inside the isolation chamber 38, disturbing the object to be cleaned, and causing the jet water flow. Pressure 11
The dust adhering to the object to be cleaned is efficiently removed by the synergistic effect of the bubble breaking pressure boiling from the bottom and the dust passing through the coarse net 30 as indicated by an arrow 43 and carried downstream.

As shown in FIGS. 6 and 7, a fine net 47 is provided on the front surface of the conveyor 17 so as to open and close vertically with a shaft 46 as a fulcrum relative to the frame 45. This shaft 46
A gear 48 fixed to one end of the motor 3 and the motor 3 in FIG.
The gear 39 fixed to the shaft 6 is connected via an endless chain to form mechanical interlocking means by such connection. When the motor 36 is operated by the manual switch 70, the opening / closing operation of the coarse net 30 and the opening / closing operation of the fine net 47 are synchronized. When the object to be cleaned is washed in the isolation chamber 38, each dust passing through the coarse net 30 can be captured by the fine net 47 downstream. Raised bodies 71 are provided on the walls on both sides of the water tank in order to eliminate gaps on both sides of the fine net 47. Subsequent synchronization with the coarse net 30 and the fine net allows the already-washed material to be automatically carried out by the carry-out conveyor 17.
