Embodiment Construction

[0020] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0021] like figure 1 As shown in the water tank liner of the existing heat pump water heater, since the installation port 7 of the electric heater is arranged at the lower part of the box body 1, the heat exchange tube 2 needs to be installed at the lower part of the box body 1, so that the heat exchange tube 2 is located in the lower part of the box body 1. The number of lower parts of the box body 1 is reduced, which reduces the contact area between the heat exchange tubes 2 and the box body 1, thereby reducing the heat exchange efficiency.

[0022] like figure 2 The water tank liner of the heat pump water heater according to the present invention is shown, which includes a box body 1 and a heat exchanger wound on the box body 1, and the heat exc...

Abstract

The invention relates to a water tank inner container of a heat-pump water heater. The water tank inner container of the heat-pump water heater comprises a tank body and a heat exchanger wound around the tank body. The heat exchanger comprises a first collecting main, a second collecting main and a heat exchange pipe, wherein the heat exchange pipe extends along the outer surface of the tank body to communicate the first collecting main with the second collecting main, the first collecting main and the second collecting main are vertically arranged in the height direction of the tank body, the outer surface, between the first collecting main and the second collecting main and opposite to the heat exchange pipe, of the tank body is an installation surface, and an electric heater installation opening is formed in the installation surface. An electric heater is plugged into the tank body through the electric heater installation opening so as to heat water in the tank body. Due to the fact that the electric heater installation opening is arranged at the position, not provided with the heat exchange pipe, between the two collecting mains, no installation space at the lower portion of the tank body needs to be reserved for the electric heater, the number of the heat exchange pipe at the lower portion of the tank body can be increased, the contact area between the heat exchange pipe and the tank body is enlarged accordingly, and heat exchange efficiency of the heat exchange pipe and the tank body is improved.

Description

technical field [0001] The invention relates to the field of water heaters, in particular to a water tank liner of a heat pump water heater. Background technique [0002] The existing coil type heat pump water heater mainly uses a heat exchanger wound on the outer surface of the water tank to heat the water in the water tank. The electric heating rod for auxiliary heating extends into the water tank through the electric heater installation port at the lower part of the water tank to perform auxiliary heating on the water in the water tank. In order to avoid the electric heater, the heat exchange tube of the heat exchanger cannot fully wrap around the water tank box, and it is necessary to reserve the installation position of the electric heater at the lower part of the box to prevent the electric heater and the heat exchanger from interfering with each other. As a result, the contact area between the heat exchanger and the water tank is also reduced, resulting in reduced he...
