Dish washer and its control method

Abstract

The present invention discloses a dish washer which comprises the following parts: a dish washing cylinder which is used for washing the dish; a water tank which is used for accommodating the wash water supplied for the dish washing cylinder; and a heater which is used for heating the wash water contained in the water tank and supplies vapor to the dish washing cylinder. According to the invention mentioned above, the vapor is supplied to the dish washing cylinder accommodating the dish thereby easily eliminating the food residue stuck on the dish and simultaneously realizing the germicidal treatment to the dish and the dish washing cylinder. Besides, additional heater, water feeding device or nozzle for supplying the vapor is not required to be installed thereby the dish washer can be easily manufactured and the expense can be greatly reduced.

Description

technical field [0001] The present invention relates to a dishwasher, and more specifically, to a dishwasher capable of further improving the washing performance of dishes. Background technique [0002] In general, a dishwasher is a device that sprays high-pressure washing water onto bowls contained inside and washes foreign substances such as food residues stuck on the surface of the bowls. [0003] The dishwasher is provided with a water supply device for supplying washing water from the outside, and a drain device for discharging the washing water to the outside. In addition, a dishwashing tub is formed inside the dishwasher, and the dishwashing tub forms a space for accommodating and washing dishes, and a nozzle capable of spraying washing water at high pressure is installed in the dishwashing tub. [0004] The washing water sprayed to the above-mentioned dish-washing tub is stored in the sump provided on the lower side of the above-mentioned dish-washing tub, and the f...

AI Technical Summary

Problems solved by technology

[0006] However, the dishwashers in the prior art have not been able to fully improve their washing efficiency even though the aforementioned improvements have been suggested.

In particular, if the bowl is left for a long time after use and the food sticks firmly to the bowl, it will be difficult to remove it only by spraying high-pressure washing water

[0007] In order to overcome the above-mentioned problems, a pre-washing operation that performs the function of swelling will be included as mentioned before, however, this will not completely solve the above-mentioned existing problems

Also, in order to perform the above-mentioned swelling function, it will take more time and thus lengthen the washing process

[0008] And, under the situation that the used bowl is placed for a long time and the bacteria multiply, it will be difficult to remove it by the dishwasher in the prior art

Of course, a dishwasher that achieves a sterilizing effect by irradiating ultraviolet rays was introduced later, but it is only limited to the part irradiated by ultraviolet rays to achieve a sterilizing effect. In this case, it will not be able to completely solve the above problems
