Dish-washing machine steam washing device and control method thereof

Abstract

The invention discloses a dish-washing machine steam washing device and a control method thereof. The dish-washing machine steam washing device comprises a steam generator for providing steam for an inner container, and a water inlet metering assembly for controlling the water inlet flow is arranged on the inner container and connected with a tap water device; water flow channels among the tap water device, the inlet water metering assembly and the steam generator are communicated through pipelines; and a temperature sensor for detecting the temperature of the steam generator is arranged on the steam generator. The temperature sensor is provided with the anti-dry-burning temperature value K4 for triggering the water inlet metering assembly to be opened, when the temperature of the steam generator is larger than or equal to the anti-dry-burning temperature value K4, the water inlet metering assembly is opened, water is fed into the steam generator under the condition that the water flowis controlled, and when the temperature of the steam generator is too high in the heating process, water can be supplemented to the steam generator in time, and dry burning of the steam generator isprevented.

Description

technical field [0001] The invention relates to a dishwasher, in particular to a dishwasher steam washing device and a control method thereof. Background technique [0002] Before some tableware is put into the dishwasher, the pollutants on the surface of the tableware will solidify due to the air environment. Therefore, a steam generator will be installed on the inner tank of the dishwasher, and the steam generator will provide steam to the inner tank of the dishwasher. , the steam enters the inner tank and contacts the tableware, gradually softening the solid pollutants on the surface of the tableware, and then starts the spray arm in the dishwasher inner tank, and the spray arm sprays water to clean the pollutants on the tableware, so that the pollutants are separated from the surface of the tableware; but the steam occurs During the heating process of the steam generator, the temperature may be too high. If the steam generator cannot be replenished with water in time, it...

[0002] Before some tableware is put into the dishwasher, the pollutants on the surface of the tableware will solidify due to the air environment. Therefore, a steam generator will be installed on the inner tank of the dishwasher, and the steam generator will provide steam to the inner tank of the dishwasher. , the steam enters the inner tank and contacts the tableware, gradually softening the solid pollutants on the surface of the tableware, and then starts the spray arm in the dishwasher inner tank, and the spray arm sprays water to clean the pollutants on the tableware, so that the pollutants are separated from the surface of the tableware; but the steam occurs During the heating process of the steam generator, the temperature may be too high. If the steam generator cannot be replenished with water in time, it will lead to safety accidents; or during the water replenishment process, excessive water replenishment will prolong the washing time of the dishwasher , which increases the consumer load
