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.

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 cleaning basket 9 is formed in a circular basket having an outer diameter so as to be accommodated in the cleaning water tank 2, and a bottom screen 92 is provided at the bottom of the cylindrical body 90, and a screen cylinder is provided at the upper end of the cylindrical body 90. A portion 93 is provided, and a handle 94 is attached to the upper end of the screen tube portion 93.

The upper end 95 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.
The screen tube portion 93 of the embodiment is formed as a comb-shaped screen in which a large number of thin bars are inclined at a predetermined interval. They may be juxtaposed in the direction or formed in a lattice shape.

Further, the screen cylinder 93 is not limited to the comb-shaped screen, and may be formed of a through-hole screen, a mesh screen, a wire net, or the like in which a number of punching holes are formed. In this case, the interval between the comb teeth, the diameter of the punching holes, the size of the mesh, and the like are appropriately determined according to the type of food to be cleaned.
Further, the bottom screen 92 can also be formed of a through-hole screen, a mesh screen, a wire net, or the like in which a large number of punching holes 97 are formed.

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. .
