Problems solved by technology

[0005] However, the above-mentioned patent has the following problems: the design uses a single fan to improve the working efficiency of the evaporator, but in order to improve the working effect of the fan, the size of the fan needs to be greatly increased, which takes up a lot of installation space
At the same time, the wind flow direction of the fan is easily blocked, which affects the heat exchange efficiency of the evaporator, so that the matching between the fan and other equipment has to be fully considered when installing and designing other components of the heat pump system, which increases the difficulty of system design.

Embodiment 1

[0051] Such as figure 1 as shown in figure 1 As shown, a heat pump dishwasher is disclosed in this embodiment. The dishwasher includes a processing chamber not shown in the figure; the processing chamber is provided with a spray port, and the spray port is provided with washing water through a washing water channel to spray and clean the tableware located in the processing chamber. The washing water circuit is connected with a water inlet valve, a respirator, a drainage pump, a circulating pump and a spray port. The washing water enters the washing water channel through the water inlet valve, flows into the treatment chamber equipped with tableware, circulates the washing water in the washing water channel through the circulation pump, and sprays the tableware on the tableware through the spray port. After cleaning, the dirty water is discharged through the drain pump, and the respirator is used to prevent siphoning of the washing water channel.

[0052] In order to improve...

Embodiment 2

[0068] Such as Figure 1 to Figure 4 As shown, the evaporator 5 of the present embodiment is located at the bottom of the processing chamber, and the bottom of the processing chamber has a protrusion protruding from the lower surface, such as Figure 13 and Figure 14 As shown, the surface of the evaporator 5 has an inner concave portion 52 that cooperates with the convex portion and is depressed inward. The protruding portion is a protruding surface formed by protruding outward from the lower surface of the processing chamber, and / or a component installed outside the processing chamber and fixed to the lower surface of the processing chamber. The components are different according to design requirements, and may be a sump 9 for collecting washing water in the treatment chamber, and / or a water diversion valve 11 for controlling washing water in a dishwasher.

[0069] In this embodiment, the protrusion is the sump 9 . The sump 9 is located at the bottom of the dishwasher, an...

Embodiment 3

[0077] In this embodiment, the latent heat released by the condenser is used to heat the washing water. When washing, tap water enters the dishwasher after being softened by the softener through the water inlet valve. The circulation pump drives the washing water to wash the tableware through the shower. When the washing water needs to be heated, the circulating pump drives the water through the condenser (casing heat exchanger), and then the tableware is washed through the shower. Such as Figure 5 As shown, the condenser of the present invention is a jacketed heat exchanger, such as Figure 7 As shown, the sleeve-and-tube heat exchanger includes a plurality of heat exchange sleeves 1 bent in the same direction; The water pipelines communicate with each other, and the outer pipe 101 communicates with the heat pump working medium. When the washing water flows through the inner tube 102 of the sleeve-and-tube heat exchanger, the heat pump working fluid in the tube of the co...

Abstract

The invention discloses a dish-washing machine with a heat pump. The dish-washing machine comprises a heat pump system mounted in the dish-washing machine; and the heat pump system comprises an evaporator, and a plurality of fans used for accelerating air flowing on the surface of the evaporator are arranged outside the evaporator, wherein the two or more adjacent fans are arranged at intervals. By adopting the multiple fans arranged in a split mode, the requirement of equipment compactness is met, the overall size of the heat pump system is decreased, and meanwhile through the fans arranged in the split mode, the problems that air is blocked by large-size components in the wind flowing direction, and consequently air flowing is influenced, and the working efficiency of the evaporator is lowered are solved.

Description

technical field [0001] The invention belongs to the field of kitchen equipment, and in particular relates to a heat pump dishwasher. Background technique [0002] Dishwashers are equipment used to automatically clean tableware such as bowls, chopsticks, plates, plates, knives, forks, etc. According to the structure, they can be divided into two categories: box type and conveyor type. It reduces labor intensity, improves work efficiency, and improves cleanliness and sanitation for the cooks in restaurants, hotels, and canteens of government agencies. Now, a variety of small dishwashers are on the market and are gradually entering ordinary families. [0003] Existing dishwashers all use heating tubes for the dishwasher. The heating tubes are built into the water tank at the bottom of the liner. When washing, the heating tubes are used to heat while the circulating pump circulates water to wash the dishes. But this method consumes a lot of power and the drying is not complete...
