Embodiment Construction
[0030] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.
[0031] see figure 1 As shown, it shows a structural block diagram of an embodiment of the dishwasher of the present invention. Such as figure 1 As shown in , the dishwasher 1 of the present invention includes a dishwasher treatment chamber 2 for washing tableware, and an upper spray arm 3 , a middle spray arm 4 and a bottom spray arm 5 are arranged in the treatment chamber 2 . A water collection tank 6 is formed at the bottom of the treatment chamber 2, and a water inlet valve 7 communicates with the water collection tank 6, through which cleaning water can be injected into the water collection tank 6 of the treatment chamber. A circulating water pump 8 is communicated with the sump 6 , and the circulating water pump 8 pumps the cleaning water in the sump 6 into the upper spray arm 3 , the middle spray arm 4 and the bottom spray arm 5 . An electric h...

The invention provides a heat pump dish washing machine and a control method thereof. The dish washing machine comprises a process chamber provided with tableware cleaning space, a drying condenser used for conducting condensation on air of the process chamber and a first fan used for leading the air of the process chamber to the drying condenser, the dish washing machine further comprises a heat pump system, the heat pump system comprises a compressor, a condenser, a throttling device and an evaporator which are connected to form a refrigerant circulation loop, and the condenser of the heat pump can heat cleaning water of the process chamber; the dish washing machine further comprises a second fan used for leading cooling air after heat exchange of the evaporator of the heat system is conducted to the drying condenser. The dish washing machine is heated by the heat pump, when drying is conducted, heat exchange between the dish washing machine and the drying condenser through the cooled air of the evaporator is conducted, the drying process can be accelerated, and the energy is saved.
Description
[0001] 【Technical field】 [0002] The invention belongs to the field of dishwashers, in particular to a dishwasher with a heat pump system and a control method thereof. [0003] 【Background technique】 [0004] When the existing dishwasher washes the tableware, it usually cleans the tableware by filling water into the dishwasher, and then pumping the water into the spray pipe in the dishwasher through a water pump. Because tableware greasy dirt needs to use hot water to clean, existing dishwasher usually adopts the mode of electric heating, and electric heater is set on the pipeline that water pump pumps water into spray pipe to heat water. [0005] Because electric heating needs to consume a lot of electric energy, a dishwasher using a heat pump heating system appeared later. This dishwasher includes a heat pump system, wherein the heat pump system includes a compressor, a condenser, a throttling device and an evaporator. Heat exchange cycle system. The refrigerant becomes a ...
