Description

Dish washing machine with swinging plate {DISH WASHER HAVING SHAKING RACK}

The present invention relates to a dishwasher, and more particularly, the washing plate for dishwashing is installed to swing up and down so that the water sprayed during washing and rinsing is changed evenly by changing the angle of the dishwashing surface. The present invention relates to a dishwasher having a rocking wash plate that maximizes the cleaning effect and saves detergent and materials.

Generally, dishwashers are kitchen appliances that automatically wash, dry and sterilize dishes using water, electricity and detergent.

The first dishwasher, developed by Joel Houghton in 1850, was simply a wooden machine that manually rotated the wheels to water the bowl. Later, Josephine Cochrane created a hand-operated dishwasher, and when it became a huge concern after being released at the 1893 World's Fair, he started his own company and started making dishwashers. It's the first time.

In addition, the improved dishwasher has evolved into a fully automated device with heated drying, water spots prevention, noise and water usage reduction technologies.

The dishwasher sets the dishes inside the housing, replenishes the detergent and rinse, presses the washing button, performs a series of processes such as soaking, main washing and rinsing, and then drying process. After drying, the power is automatically cut off.

Meanwhile, in the case of a commercial dishwasher, a housing having a large-capacity structure capable of processing a large amount of dishes, a washing chamber having a sliding up and down link on one side of the housing, a pump located inside the housing under the washing chamber, A control circuit for controlling an operation program of the washing machine, a washing water tank, a rinsing water tank, a hot / cold water supply device, a detergent supply device, and a water injection device are provided.

In such a conventional commercial dishwasher, the water jetting device is typically a pipe shape coupled to the upper and lower rotary plates equipped with rinse jet nozzles and supplied with water to perform cleaning spraying on the vertical upper or lower portions of the upper and lower rotary plates. Have cleaning spray nozzles. And the rack or washing plate, such as a basket on which the dishes are mounted, is placed on the holder fixed to the inner surface of the washing room, thereby being disposed between the rotating plates. Thereafter, each of the rinsing spray nozzles and the washing spray nozzles rotates with the rotating plate during the operation of the dishwasher, thereby spraying hot or cold water. The sprayed water stem is applied to the inner and outer surfaces of the dishes mounted on the washing plate by a predetermined pressure and an inclination angle according to the nozzle or rotation, thereby washing and rinsing the dirt and scale of the dishes.

However, in the case of the conventional commercial dishwasher, since the water flowing from the rinse jet nozzle and the jet jet nozzle rotates correspondingly to the rotation of the rotating plate, pressure is applied only to a part of the surface of the dish placed in a fixed position in a predetermined pattern. It is also known as the 'square zone' where water pressure does not work.

Dirt and grime in these blind areas, of course, will most likely be cleaned by running the dishwasher for a long time, using a lot of detergent, increasing the hot water temperature, or waiting for the water to come into contact with the dirt on the surface of the dish, As a result, the consumption of water, detergent, and electricity, which are used as main resources for the operation of the dishwasher, has a disadvantage in that it is further increased. Such a conventional dishwasher has a relatively low operating efficiency and performance, creating a problem that the maintenance cost more than the production cost, there is a problem that brings the environment and resource waste nationally.

Accordingly, an object of the present invention is to solve the problems of the prior art, by moving the edge of the washing plate of the dishwasher up and down to the washing surface of the dish using a lifting means to move the washing plate as a whole. Water and detergent can be evenly sprayed to provide a dishwasher having a rocking wash plate to enable more efficient dishwashing.
