In some embodiments of the present invention, the heating device 3 comprises a compressor 31, a condenser 32, a throttling device 33 and an evaporator 34 which are connected end to end in sequence to constitute a refrigerant cycle. That is, according to some embodiments of the present invention, the dishwasher 100 is a heat pump heating type dishwasher 100, and the refrigerant undergoes the processes of compression, condensation heat release, throttling expansion, and evaporation heat absorption in the heat pump system, and after the low-grade energy is converted into the high-grade heat energy, the high-grade heat energy is released into the washing water, so as to achieve the purpose of high-efficiency and low-energy heating. Compared with the traditional electric heating, the coefficient of performance of the heat pump heating system is 3-4 times or even higher than that of the common electric heating technology. The dishwasher 100 adopting the heat pump heating technology has obvious energy-saving effect, can greatly reduce the use energy consumption of the dishwasher 100, and is an effective means for reducing the use energy consumption of the dishwasher 100.

In addition, in order to improve the heat exchange efficiency between the washing water and the refrigerant, the first liquid flow channel and the second liquid flow channel may be designed to be relatively complicated, so that the flow resistance of the first liquid flow channel may be increased, and thus, the direct connection of the condenser 32 to the flow path of the original washing system may cause problems such as the decrease of the spraying pressure of the spray arm 2 of the dishwasher 100 or the increase of the power consumption of the washing pump 4, especially during the non-heating period. For this reason, by using the dishwasher 100 according to the embodiment of the present invention, by providing the shunt valve assembly 6, it is possible to solve the problem that the flow resistance is large due to the flow of the washing water through the condenser 32 during the non-heating period. In addition, the water diversion valve assembly 6 of the dish washing machine 100 is assembled with the water collection tank 5 to form an assembly whole 5-6, so that a connecting pipe between the water diversion valve assembly 6 and the water collection tank 5 is omitted, and the overall structure of the dish washing machine 100 is compact.
