Abstract

The invention provides a heat pump type tableware washer and a control method thereof. The washer is added with a heat pump device comprising a compressor, a condenser, a throttle device, an evaporator and an evaporator fan. The condenser is disposed on a line where a circulating water pump is located; a heating heat-exchange passage is also disposed between a housing and a treatment chamber, the evaporator and the evaporator fan of the heat pump device are received in the heating heat-exchange passage, and both an air inlet and an air outlet of the heating heat-exchange passage are arranged in the front of the housing. The heat pump device provides hot water in a washing stage, decreasing energy consumption; both the air inlet and the air outlet are arranged in the front of a body, enabling air to circulate more smoothly, avoiding the problem that unsmooth air circulation in a cupboard where the washer is mounted may cause poor heat dissipation of a chamber of the compressor; a guarantee is given to both timely discharge of heat of the chamber of the compressor and reduction of exhaust temperature, thus prolonging life of the compressor.

Description

technical field [0001] The present invention relates to a dishwasher for domestic or commercial use. Background technique [0002] Existing household or commercial dishwashing machines are usually electric heating, and the typical structure is as follows: figure 1 As shown, the machine housing is provided with a treatment chamber 2, and a plurality of spray arms (3, 4, 5) are arranged in the treatment chamber 2, and the tableware to be cleaned is put into a fixed basket located in the treatment chamber, and the bottom of the treatment chamber A water collection tank 10 is provided; a drying condenser 6, a water inlet valve 9, a circulating water pump 11, an electric heater 12 and a drainage pump 13 are arranged in the gap between the processing chamber and the machine shell. [0003] The cleaning process of this washing machine is divided into two stages: the washing stage and the drying stage. [0004] The washing stage includes four steps of pre-washing-main washing-pre-...
