Abstract

The invention relates to a device for making hot water, specifically to a pressure-bearing water tank for a heat pump water heater, comprising a tank body and more than one refrigerant pipe. A water outlet is arranged at the top end of the tank body. A water inlet is arranged at bottom of the tank body. The tank body is internally provided with a cylindrical body in an aerial way. The cylindrical body is provided with a column body axially. A plurality of positioning plates are arranged in a gap between the external wall of the column body and the internal wall of the cylindrical body and are spirally arranged along the gap at intervals. The refrigerant pipes coil by passing through the positioning plates along the gap, respectively. The inlets and the outlets of the refrigerant pipes are respectively connected with a general inlet and a general outlet on the wall of the tank body. Both of the upper end and the lower end of the cylindrical body are open. The structure of the invention is designed reasonably; water in the water tank can be heated circularly, and the heating area is increased so that water in the tank can be kept at high temperature which is more uniform, thereby improving plot ratio of the water tank.

Description

technical field [0001] The invention relates to a hot water heating device, in particular to a pressurized water tank for a heat pump water heater. Background technique [0002] The pressurized water tank used in the existing heat pump water heater is to immerse the refrigerant coil in the water tank, and the refrigerant exchanges heat with the water to generate hot water. The water convection is very slow, the heating area is small, the energy efficiency of the hot water machine is relatively low, and the utilization rate of the water tank volume is low. Contents of the invention [0003] Therefore, the object of the present invention is to provide a heat pump water heater water tank that enables water to circulate in the water tank to improve the utilization rate of the water tank volume. [0004] The purpose of the present invention is achieved like this: [0005] A water tank for a heat pump water heater, comprising a tank body and a refrigerant pipe. The top of the ...
