BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vegetable washer, and more particularly, to a vegetable washer configured to automatically wash pesticides and various foreign matters on surfaces of fruits and vegetables by generating air bubbles in a washing tank.

Recently, with increasing consumer's desire for convenience of life and increasing awareness of various environmental problems caused by waste of detergent and water, interest in vegetable washers has increased.

The vegetable washer that is currently being developed mainly uses a method of generating micro bubbles using ultrasonic waves. However, since the ultrasonic vegetable washer is not only expensive, but also has low cleaning power, there is a problem in that an additional device is required such as generating a whirlwind in the washing tank.

The apparatus shown in FIG. 1 is a vegetable washer (hereinafter referred to as an “air drop vegetable washer”) configured to generate air bubbles in the washing tank 2 by injection of high pressure air instead of ultrasonic waves. Patent application (No. 10-1993-0013729) on 20 and patent registration (No. 10-0100365-0000) on June 7, 1996.

The operation structure of the air bubble vegetable washer will be briefly described with reference to FIGS. 1 and 2, and the vegetable washer 1 has pores 3a formed at a lower portion of the washing tank 2 having a plurality of through holes 2a. The bubble generating plate 3 is installed, so that the high pressure air introduced along the air hose 4 when the blower 5 is operated passes through the pores 3a of the bubble generating plate 3 and contains water. 2) Air bubbles are generated inside.

On the other hand, since the air bubble vegetable washer 1 is installed at a position lower than the washing tank 2 in which the blower 5 is filled with water, there is a problem that water flows back from the washing tank 2 side to the blower 5 side. Can be generated. Therefore, the air hose 4 is comprised so that the intermediate part may be bent once in the place where the level of the water filled in the washing tank 2 is higher.

The air bubble vegetable washer has the advantage of excellent cleaning power and low manufacturing price than ultrasonic vegetable washer.

However, the above vegetable washer (1) is designed and intended to be used as a built-in sink or used in a separate place, so put the vegetable washer on the sink most often kitchen work, kitchen utensils There was not enough to use it freely. For example, when the vegetable washer shown in FIG. 1 is tilted to the right, the air hose 4 is disposed at a lower position than the washing tank 2 so that the water in the washing tank 2 is moved along the air hose 4 toward the blower 5. It can be easily reversed.

In addition, the vegetable washing machine (1), the components such as drain pipes, blowers are arranged in the vertical length direction, the height is too high to be placed in the sink of the sink. Moreover, in order to prevent the backflow of water to the blower 5 side, the bending point of the air hose 4 is set higher than the upper end height of the overflow pipe 7, and the height of a vegetable washing machine is inevitably higher.

In addition, the vegetable washer (1), the overflow pipe (7) to prevent the water in the washing tank 2 overflow, and a separate drain valve for selectively draining the water in the washing tank (2) (6) The number of parts required for manufacturing the product, such as the use of a large number, and the structure is relatively complicated.

In addition, the vegetable washing machine (1), the body of the vegetable washing machine is made in one body is inconvenient when you want to clean the inside of the vegetable washing machine. In particular, in order to separate the bubble generating plate (3), it is inconvenient to separate all the drain side components of the vegetable washer.

The present invention has been proposed to solve the above problems, and to provide a vegetable washer so that water does not flow back from the washing tank to the blower even if the user tilts the vegetable washer in any direction. In order to prevent water from flowing back to the blower side, a separate valve may be installed at the air hose or the air hose connecting portion, but the present invention is intended to provide a simpler and less expensive backflow prevention structure.

In addition, when used, it can be used after simply mounted on the sink sink, and after use to provide a transportable vegetable washer configured to be stored in a separate place.
