Embodiment 1

[0048] Such as Figure 1-2 As shown, a dishwasher includes a processing chamber 100 for washing dishes with washing water, a cooling device 301, and a cooling system, and the cooling system carries a heat exchange material and cools the processing chamber wall 101 after being cooled by the cooling device 301, so that The water vapor in the processing chamber 100 condenses on the processing chamber wall 101 to realize the drying of the tableware.

[0049] By setting up a cooling system, the cooling system carries the heat exchange material through the cooling device, and uses the cooling function of the cooling device 301 to cool down the heat exchange material passing through the cooling device 301, and the cooled heat exchange material exchanges heat with the processing chamber wall 101, The temperature of the heat-exchanging substance rises, the temperature of the processing chamber wall 101 decreases, and the water vapor in the cooling chamber encounters the lower temperatu...

Embodiment 2

[0052] Such as Figure 1-2 As shown, this embodiment is a further limitation of Embodiment 1. The dishwasher also includes a heat pump cycle system. The heat pump cycle system includes a compressor 302, a condenser 303, a throttling device 304, and an evaporator 301. The compressor 302, condenser The device 303, the throttling device 304 and the evaporator 301 are connected to each other to form a refrigerant circuit. The cooling device 301 is an evaporator 301 of a heat pump cycle system. The cooling system carries a heat exchange substance through the evaporator 301 , and the heat exchange substance cools down the temperature of the processing chamber wall 101 after being cooled by the evaporator 301 .

[0053] The compressor 302 is turned on, the cooling system carries the heat exchange material through the evaporator 301, the refrigerant absorbs the energy of the heat exchange material outside the evaporator 301 and evaporates itself, so that the temperature of the heat ex...

Embodiment 3

[0089] Such as Figure 1-2 As shown, this embodiment is a specific implementation of Embodiment 1 and Embodiment 2. A dishwasher includes a door body 103, a body 102, a drainage system, a spray system, a heat pump circulation system and a cooling system. A processing chamber 100 is provided in the body, and the processing chamber includes a coverable body and a cover, and the body and the cover are closed to form a closed processing chamber. The washing water enters the treatment chamber 100 through a water inlet pipeline, on which a water inlet valve 400 and a respirator 401 are arranged. The user opens the door body and places the tableware to be washed into the processing chamber 100 through the opening. According to needs, a shelving basket or a shelving rack may also be provided in the processing chamber 100, and the tableware is placed on the shelving basket or the shelving rack.

[0090] A circulating water channel 307 is provided at the bottom of the dishwasher, and ...

Abstract

The invention belongs to the field of dish washing machines and specifically relates to a dish washing machine and a control method. The dish washing machine comprises a processing chamber, a coolingdevice and a cooling system, wherein the processing chamber is used for washing tableware with wash water; a heat exchange substance carried by the cooling system is cooled by the cooling device, andthen the wall of the processing chamber is cooled, so that water vapor in the processing chamber is condensed on the wall of the processing chamber, and the tableware can be dried. The dish washing machine has the beneficial effects that the heat exchange substance of the cooling device is cooled by utilizing a cooling function of the cooling device and by arranging the cooling system, heat exchange is performed between the cooled heat exchange substance and the wall of the processing chamber, the temperature of the heat exchange substance is increased, the temperature of the wall of the processing chamber is decreased, the water vapor in a cooling chamber is condensed on the inner wall of the processing chamber when touching the wall of the processing chamber at lower temperature, so thatair in the processing chamber is dried, and water on the tableware is evaporated, therefore, a function of drying the tableware is achieved.

Description

technical field [0001] The invention belongs to the field of dishwashers, and in particular relates to a dishwasher and a control method. Background technique [0002] Dishwasher is a device that automatically cleans tableware such as bowls, chopsticks, plates, plates, knives, forks, etc. It has the characteristics of saving time and effort, and strong decontamination ability. The first patent for machine dishwashing appeared in 1850. In 1929, the German company Miele produced the first electric household dishwasher in Europe. Japan was the first to research dishwashers in Asia. [0003] At present, the fully automatic dishwashers on the market can be divided into two categories: household and commercial. Household fully automatic dishwashers are only suitable for households, mainly including cabinet type, desktop type and integrated sink type. According to the structure, commercial dishwashers can be divided into two categories: box type and conveyor type, which reduce lab...
