Embodiment Construction

[0025] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0026] The invention provides a water tank, such as figure 2 and image 3 As shown, the water tank includes an inner tank 1, an outer coil heat exchanger 2 is wrapped on the outer wall of the inner tank 1, and a spiral water inlet pipe 3 in a spiral structure is arranged inside the inner tank 1, and the spiral water inlet pipe 3 is attached and installed On the inner wall of the liner 1.

[0027] In this embodiment, the above-mentioned water tank is introduced into the bottom of the inner tank 1 through the spiral water inlet pipe 3 , specifically, the inlet of the spiral water inlet pipe 3 is located at the upper end of the inner tank 1 , and the outlet is located at the bottom of the inner tank 1 .

[0028] A hot water outlet pipe 5 is arranged on the top of the inner tank 1, and the hot water ...

Abstract

The invention belongs to the technical field of water heaters, and discloses a water tank. The water tank comprises an inner container, the outer wall of the inner container is wrapped with an outer coil pipe heat exchanger, the inner wall of the inner container is provided with a spiral water inlet pipe in an attaching manner, and water enters the water tank, passes through the spiral water inletpipe and then is led into the inner container. The spiral water inlet pipe is arranged on the inner wall of the inner container of the water tank in the attaching manner, after the water enters the water tank, and enters through an inlet of the spiral water inlet pipe, under the water supplementing pressure effect, the ware and the outer coil pipe heat exchanger are subjected to forced convectionheat exchange, the heat exchange coefficient and the heat exchange efficiency are improved, cold water entering the spiral water inlet pipe directly exchanges heat with the outer coil pipe heat exchanger, the temperature of a refrigerant medium in the outer coil pipe heat exchanger does not need to be very high, the heat exchange needs can be met, the energy consumption is effectively reduced, the heat exchange property is improved, and the burdens on a heat pump water heater compressor are reduced.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a water tank and a heat pump water heater. Background technique [0002] At present, nearly 90% of household air source heat pump water heaters in the market are static heating air source heat pump water heaters, and its mainstream structure is that the heat exchanger 100 is wrapped on the outside of the water tank liner 101 and separated from the water to prevent the heat exchanger 100 from corroding and scaling (see figure 1 ), the lower end of the water tank is provided with a cold water inlet pipe 102, and the upper end is provided with a hot water outlet pipe 103. During the process of making hot water, the cold water enters the inner tank 101 through the cold water inlet pipe 102, and the heated water side is connected with the inner tank by natural convection. The heat exchanger 100 wrapped outside the inner tank 101 exchanges heat so that the water temperature grad...
