Problems solved by technology

[0005] However, the above-mentioned patent has the following problems: the design of the evaporator does not consider the matching problem with other parts near the evaporator
However, due to functional requirements, the bottom of the dishwasher will be equipped with large parts connected to many water pipes. Such parts themselves take up a relatively large space. , it is bound to greatly increase the overall size of the dishwasher
Not only can it not meet the requirements of compact equipment, but the air flowing in the air duct will also be blocked by these components, reducing the air flow speed and reducing the heat exchange efficiency of the evaporator

Embodiment 1

[0052] Such as 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.

[0053] In order to improve the cleaning effect o...

Embodiment 2

[0065] Such as Figure 1 to Figure 4 As shown, the exterior of the evaporator in this embodiment is provided with a plurality of fans 4 for accelerating the air flow on the surface of the evaporator 6, wherein at least two adjacent fans 4 are arranged at intervals. In this embodiment, the number of fans is two, and the size and / or power and / or model of the fans are the same.

[0066] Such as figure 1 As shown, two fans 4 arranged at intervals are arranged side by side on the same side of the heat exchange surface of the evaporator 5 to accelerate the air flow velocity on the heat exchange surface of the evaporator 5 near the fans 4 . The side-by-side arrangement of the fans ensures the area of ​​the accelerated air flow, thereby ensuring the working efficiency of the evaporator. At the same time, fan gaps 14 are formed between the fans arranged at intervals.

[0067]The dishwasher of the present invention comprises a treatment chamber for washing dishes, said treatment cham...

Embodiment 3

[0078] 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 heat pump type dish washing machine. The heat pump type dish washing machine comprises a treatment chamber used for washing tableware and a heat pump system; and the heat pump system comprises an evaporator, the evaporator is located at the bottom of the treatment chamber, a protruding part protruding out of the lower surface is arranged at the bottom of the treatment chamber, and an inward-sunken part matched with the protruding part and sunken inwards is arranged on the surface of the evaporator. By improvement in the evaporator, the dish washing machine is matched with other parts to meet the compact requirement for the heat pump type dish washing machine, the overall size of the heat pump system is decreased, meanwhile, through an inward-sunken air duct in the evaporator, the kinetic energy loss caused by air flowing between the protruding part and the evaporator is also reduced, and the requirement for heat exchanging on the surface of the evaporator is ensured.

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...
