Description

Technical Field

[0001] The utility model specifically relates to a heat pump water heater. Background Art

[0002] Air source heat pump water heaters are becoming more and more popular in the market because of their obvious energy-saving effects. Air source heat pump water heaters can be generally divided into two types: split air source heat pump water heaters and integral heat pump water heaters. Split air source heat pump water heaters are further divided into refrigerant circulation air source heat pump water heaters and water circulation air source heat pump water heaters. Refrigerant circulation air source heat pump water heaters require high installation process requirements due to the need to connect refrigerant pipes, and require professional technicians to complete; while water circulation air source heat pump water heaters need to be equipped with a circulating water pump, which increases both product costs and the probability of system failure. In order to save installation and maintenance costs and improve the stability and reliability of the system, integral heat pump water heaters have been well promoted in some countries.

[0003] The application number of an invention patent application is CN201310320865.1. The name of the invention application is an integrated heat pump water heater.

The cold water inlet is located at the lower part of the insulated water tank, the hot water outlet is located at the top of the water tank, the cold water supply port is located at the bottom of the water tank, and it opens directly inside the water tank. The hot water inlet is located at the bottom of the water tank and is connected to a section of insulated pipe inside the water tank, and its opening is located at the upper part of the water tank; the hot water inlet of the insulated water tank is connected to the upper interface of the condensing heat exchanger, and the cooling water supply port of the insulated water tank is connected to the lower water inlet of the condensing heat exchanger through a connecting pipe. The condensing heat exchanger is installed vertically, and the exhaust pipe of the compressor enters from the upper part of the condensing heat exchanger and exits from the lower part. The condensing heat exchanger is generally provided with an insulation layer.

[0004] Before transportation, a wooden board needs to be installed on the bottom of the shell, which acts as a buffer and prevents the bottom of the shell from being scratched. The shell and the wooden board are connected by screws. When transported to the designated place, the screws need to be removed and the shell and the wooden board need to be separated. The screws need to be stored separately, which is inconvenient to carry. In addition, the wooden board is easily damaged due to repeated installation and removal of screws, and the wooden board needs to be replaced, which increases production costs.

DETAILED DESCRIPTION

[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0023] Reference below Figures 1 to 4 A heat pump water heater according to an embodiment of the utility model is described, comprising a shell 1, a positioning foot 101 is provided on the bottom surface of the shell 1, a plate body 2 is provided below the positioning foot 101, a through opening 104 is provided on the positioning foot 101, a socket 203 is provided on the upper surface of the plate body 2, a connecting piece 3 is provided between the positioning foot 101 and the plate body 2, an upper buckle portion 302 is provided at the upper end of the connecting piece 3, the upper buckle portion 302 is buckled in the through opening 104, and a lower buckle portion 303 is provided at the lower end of the connecting piece 3, the lower buckle portion 303 is buckled in the socket 203.

[0024] In this structure, a connecting piece 3 is provided between the positioning foot 101 and the plate body 2, the upper buckle portion 302 of the connecting piece 3 is buckled on the through hole 104, and the lower buckle portion 303 of the connecting piece 3 is buckled on the socket 203, so that the plate body 2 is quickly fixed; no additional storage is required, and installation and disassembly are convenient, thereby reducing production costs.

[0025] Among them, the lower buckle part 303 of the connecting piece 3 is first installed on the socket 203 on the board body 2, and then the shell 1 is placed on the board body 2, and the upper buckle part 302 of the connecting piece 3 is buckled on the through-hole 104 of the positioning foot 101, so that the shell 1 and the board body 2 are fixed. The positioning foot 101 is welded to the bottom surface of the shell 1. The front and rear ends of the positioning foot 101 extend outside the shell 1. The connecting piece 3 needs to be used in conjunction with the tool 4. The bottom surface of the tool 4 is provided with a recessed position 401, and the recessed position 401 is respectively suitable for the upper buckle part 302 and the lower buckle part 303. The upper buckle part 302 and the lower buckle part 303 are respectively placed on the recessed position 401. When the tool 4 moves downward, the recessed position 401 squeezes the upper buckle part 302 or the lower buckle part 303, so that the diameter of the upper buckle part 302 or the lower buckle part 303 is reduced, and the upper buckle part 302 can be detached from the through-hole 104, and the lower buckle part 303 can be detached from the socket 203. In addition, the buckle portion 303 contacts the socket 203, and the inner edge of the socket 203 squeezes the surface of the buckle portion 303, causing the buckle portion 303 to shrink inward, so that the radius of the buckle portion 303 is smaller than the radius of the socket, and the buckle portion 303 can pass through the socket 203.

[0026] The upper buckle part 302 and the lower buckle part 303 of the present structure are connected by a connecting column 301. The connecting column 301 allows a certain distance between the upper buckle part 302 and the lower buckle part 303, and the positioning foot 101 is placed within the distance.

[0027] The buckle portion 302 of the present structure is provided with an upper recess 304, the lower end of which extends to the upper end of the connecting column 301. The upper recess 304 provides a space for deformation. The buckle portion 302 is trapezoidal in shape, so that the inner edge of the through hole 104 can be pressed against the surface of the buckle portion 302.

[0028] The buckle portion 303 of the present structure is provided with a lower concave position 305, the upper end of which extends to the lower end of the connecting column 301. The lower concave position 305 provides a deformation space, so that the inner edge of the socket 203 can be pressed against the surface of the buckle portion 303.

[0029] The plate body 2 of this structure is provided with a top plate 202, and the socket 203 is located on the top plate 202. A cavity 201 is provided below the top plate 202 of this structure, and the socket 203 is connected to the cavity 201. The cavity 201 allows the tool 4 to be placed in the socket 203 for operation.

[0030] The upper surface of the housing 1 of this structure is provided with a first heat dissipation opening 102. The side surface of the housing 1 of this structure is provided with a second heat dissipation opening 103. The first heat dissipation opening 102 and the second heat dissipation opening 103 are used for heat dissipation in the housing 1. The shape of the through opening 104 of this structure is adapted to the shape of the lower buckle portion 303, and can limit the downward displacement of the lower buckle portion 303.

[0031] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
