[0042] Embodiment one, such as figure 1 and figure 2 As shown, the present invention provides a heat pump water heater, which generally includes a heat pump unit 100 and a water tank 200 . The basic components of the heat pump unit 100 are a base, a compressor installed on the base, a heat exchanger, a throttling device and a fan, and the water tank 200 includes an outer shell (not shown), an inner tank 201 and an auxiliary heat exchanger 202. The compressor, the heat exchanger, the throttling device and the auxiliary heat exchanger 202 are connected to form a refrigerant circulation flow path, and the water in the inner tank 201 is heated and treated by using the principle of a heat pump. The above is the basic configuration of a conventional heat pump water heater, and will not be limited or repeated here.

[0043] During actual installation and use, the heat pump unit 100 is fixed on the indoor roof by means of hanging installation, and is hidden on the ceiling 1000 . The water tank 200 is placed in the user's home in a conventional installation manner.

[0044] For the heat pump unit 100 to meet the requirements of hanging and concealed installation, it is necessary to make corresponding improvements in terms of the layout of its internal components, the hanging installation of the overall equipment, and the way of air circulation. The details are described below with reference to the drawings.

[0045] Embodiment two, such as image 3 and Figure 4 As shown, in order to effectively reduce the overall height of the heat pump unit to meet the hidden installation of the heat pump unit in the ceiling. The heat pump unit includes: a base 1 , a compressor 2 , a heat exchanger 3 and a fan 4 . In order to meet the requirements of hanging installation, the base 1 is provided with a mounting part 10 for hanging installation on the base 1; the heat exchanger 3 is arranged on the base 1; the fan 4 is used to drive airflow through the heat exchanger 3 Perform heat exchange. Wherein, in order to effectively reduce the overall height of the heat pump unit, the compressor 2 is arranged horizontally and installed on the base 1 ; the fan 4 and the heat exchanger 3 are located on the same side of the compressor 2 .

[0046] Specifically, the compressors 2 in the heat pump unit are horizontally arranged and fixedly installed on the base 1 . In this way, the height space occupied by the compressor 2 can be effectively reduced, so as to effectively reduce the overall height of the heat pump unit. At the same time, the fan 4 and the heat exchanger 3 are located on the same side of the compressor 2, so that the fan 4 mainly blows or sucks the heat exchanger 3, so as to reduce the overall size of the fan 4 and prevent the fan 4 from causing the height of the heat pump unit to increase. increase.

[0047]In some embodiments, for the convenience of installing the compressor 2, such as Image 6 As shown, one end of the base 1 is provided with an installation platform 11 , and the compressor 2 is arranged on the installation platform 11 . Specifically, the compressor 2 is horizontally installed and fixed on the installation platform 11 , and the installation platform 11 is located at one end of the base 1 , so that the compressor 2 is arranged at a corresponding end of the base 1 . Preferably, in order to reduce the impact of vibration caused by the operation of the compressor 2, the installation platform 11 is provided with an installation bracket 12, and a vibration damping pad 13 is also arranged between the installation bracket 12 and the installation platform 11, and the compressor 2 is installed on the installation bracket 12 superior.

[0048] Wherein, for the mounting bracket 12, in order to be able to cooperate with the vibration damping pad 13 to achieve a better vibration damping effect, the mounting platform 11 is provided with two mounting brackets 12 arranged side by side. The mounting bracket 12 has a fixed part 121 and is distributed on The tilting parts 122 on both sides of the fixing part 121, the fixing part 121 is fixed on the installation platform 11, and the vibration damping pad 13 is arranged between the tilting part 122 and the installation platform 11; wherein, the compressor 2 is fixed on the tilting part 122 . Specifically, the mounting bracket 12 is usually processed by sheet metal parts, which has a certain degree of elasticity, and the compressor 2 is installed on the raised portion 122, and the bottom of the raised portion 122 is pressed on the damping pad 13. The elasticity of the installation bracket 12 and the elasticity of the damping pad 13 can better dampen the vibration of the compressor 2 . Meanwhile, in a certain embodiment, in order to improve the structural strength of the base 1 to install and fix the compressor 2 , the lower surface of the installation platform 11 is provided with several reinforcing ribs 111 arranged in a staggered manner.

[0049] In some embodiments, in order to facilitate the installation of the heat exchanger 3 and meet the requirements of the overall height of the equipment, the other end of the base 1 forms a water receiving tray 14 , and the heat exchanger 3 is arranged above the water receiving tray 14 . Specifically, in actual use, the heat exchanger 3 is used for evaporative heat exchange, so condensed water will be generated on the surface of the heat exchanger 3, and the condensed water will flow into the water receiving tray 14 under the heat exchanger 3 under the action of gravity middle. The drain pan 14 is provided with a drain pipe 141 and is discharged to the outside through the drain pipe 141 . Wherein, a downwardly recessed water receiving tray 14 is formed on the base 1, and the heat exchanger 3 is arranged in the water receiving tray 14, so that the installation height of the heat exchanger 3 on the base 1 can be reduced more effectively , so that a larger-sized heat exchanger 3 can be used to improve heat exchange efficiency.

[0050] As a preferred embodiment, in order to effectively improve the heat exchange capacity of the heat exchanger 3 without increasing the height, the length dimension of the heat exchanger 3 is greater than the height dimension of the heat exchanger 3, so that the heat exchanger 3 along the The length direction of the base 1 is distributed, and the length direction of the base 1 is fully utilized to increase the heat exchange area of ​​the heat exchanger 3 .

[0051] Embodiment three, such as Figure 7 As shown, since the heat pump unit is hung and installed on the indoor roof, in order to facilitate the operator to maintain the electronic control devices later, for the base 1, the upper surface of the base 1 forms the upper mounting surface, and the lower surface of the base 1 Form the lower mounting surface. Wherein, the compressor 2, the heat exchanger 3 and the fan 4 are installed on the upper installation surface of the base 1; lower mounting surface.

[0052] After the heat pump unit is hung and installed, since the electric control board 5 is installed on the lower mounting surface of the base 1, when the electric control board 5 needs to be repaired, it is only necessary to open the ceiling to face the electric control board 5 at the bottom of the base 1. Make repairs. Wherein, for the specific configuration of the electric control board 5 , reference may be made to the control circuit board in a conventional heat pump unit, and no limitation or description is made here.

[0053] As a preferred embodiment, an installation groove 15 is formed on the lower installation surface of the base 1 , and the electric control board 5 is disposed in the installation groove 15 ; a cover plate (not shown) for the switch installation groove 15 is also provided on the base 1 . Specifically, an installation groove 15 is formed on the lower installation surface of the base 1 to facilitate the installation and fixing of the electric control board 5 so that the electric control board 5 is embedded in the base 1 . At the same time, the installation groove 15 is covered by the cover plate, which can also protect the electric control board.

[0054] In some embodiments, the compressor 2 can also be arranged at the upper part of the installation groove 15, so that wiring between the electric control board 5 and the compressor 2 on the top is more convenient. For the reinforcing rib 111, it is formed in the installation groove 15, and the electric control board 5 is supported by the reinforcing rib 111. On the one hand, it is convenient to fix the electric control board 5 on the reinforcing rib 111 by screws; on the other hand, the reinforcing rib 111 supports the electric control board 5, and the reinforcing ribs 111 are also conducive to dissipating the released heat of the electric control board 5, so as to ensure the reliable operation of the electric control board.
