Problems solved by technology

Later, air-energy water heaters appeared that rely on compressors, cold medium pipelines and other components to cooperate with the cold medium to heat water. This type of water heater needs to be equipped with a water storage tank and a device that uses air to exchange heat for the cold medium. The fins that increase the contact area with the air are connected to the upper part, which makes the volume of the device larger, and there are more components in the entire mechanism, and the connection method between the components is also more complicated, and it is impossible to use some available heat energy to heat the cold medium. , although the heating coefficient is higher than that of gas water heaters and electric water heaters, the heating coefficient is still not ideal

Embodiment Construction

[0018] Such as figure 1 As shown, the present invention is a compact heat pump water heater, including a compressor 1, a throttling device 3, a double-layer casing 4 in which the inner pipe is a refrigerant pipe 5 and the outer pipe is a water pipe 6. The present invention also includes The evaporator 2, the evaporator 2, the throttling device 3 and the compressor 1 are sequentially connected by the refrigerant medium tube 5 of the double-layer casing 4 to form a closed refrigerant medium circulation passage, and the evaporator 2 is flat and hollow , the evaporator 2 is connected in the circulation path, and its two ends are connected with the refrigerant medium pipeline. According to the reverse Carnot principle, when the compressor 1 starts to work, the refrigerant medium runs in the circulation path, the refrigerant medium enters the hollow part of the evaporator 2 from one end of the evaporator 2, and the refrigerant medium flows through the evaporator in a flat manner. A...

Abstract

The invention relates to a compact type heat-pump water heater fully utilizing remaining heat of wastewater generated by a shower. The compact type heat-pump comprises a compressor, a throttle device, a two-layer bushing and an evaporator; a circulation loop is formed by connecting the evaporator, the throttle device and the compressor through a cold medium pipe; the evaporator appears as flat and hollow form and two ends of the evaporator are respectively connected with the cold medium pipe, and then the cold medium can flow through the hollow part of the evaporator; and the evaporator is arranged at a position where the showering can reach after showering with hot water. The water heater has the advantages of high heating coefficient, compact volume, safe performance and environment-friendly property.

Description

【Technical field】 [0001] The invention relates to a heat pump water heater, in particular, it is a compact heat pump water heater which can fully utilize the residual heat energy of waste water produced by showers and is used for showers. 【Background technique】 [0002] A water heater is a device that provides hot water for people in daily life and work. The water heater is almost used in every aspect of life and work, for example, it can be used for showering. Water heaters used for showers generally have the following types according to their heating methods. The common common gas water heaters appeared earlier and are the most widely used ones. Water is heated; electric water heaters mainly rely on electric heating components to directly contact water to heat water; both of the above two water heaters have the disadvantages of low heating coefficient, low safety performance and poor environmental protection performance. In terms of safety, there are still occasional repo...
