Description

Technical Field

[0001] This utility model relates to an air source heat pump, and more particularly to an air source heat pump rapid defrosting device. Background Technology

[0002] An air source heat pump is an energy-saving device that uses high-grade energy to transfer heat from a low-grade heat source (air) to a high-grade heat source. In winter, air source heat pump units are typically used for indoor heating. The evaporator of an air source heat pump will frost up in winter because the outdoor temperature is lower than the indoor critical temperature. If defrosting is not done in time, the frost will accumulate and seriously affect its normal operation. Defrosting of air source heat pumps usually uses rapid defrosting equipment.

[0003] Existing air source heat pump rapid defrosting equipment is usually equipped with a heating mechanism to raise the temperature of the outside of the evaporator of the air source heat pump, thereby removing the frost on the outside of the evaporator. However, the water after the frost melts will accumulate inside the protective box, thus affecting the use of the protective box. Summary of the Invention

[0004] The purpose of this invention is to provide an air source heat pump rapid defrosting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An air source heat pump rapid defrosting device includes a protective box. A protective door is installed on the front end of the protective box. A heating plate is fixedly connected to the inner wall of the protective box. A support frame is installed on the top of the heating plate. An air source heat pump body is installed on the top of the support frame. A baffle is fixedly connected to the front end of the heating plate. A drain hole is provided on the top of the support frame. A drain groove is provided on the rear end of the support frame. A water collection trough is provided on the inner wall of the protective box. The inner wall of the water collection trough has an inclined surface. A drain pipe is installed at the bottom of the water collection trough. An installation groove is provided on the side surface of the protective box, with the end of the drain pipe away from the water collection trough located at the top of the installation groove. A collection box is installed inside the installation groove, with the end of the drain pipe located above the collection box. During use, the heating plate heats the inside of the protective box, thereby defrosting the exterior of the air source heat pump body. The frost melts into water and drains from the support frame through the drain trough. It then enters the bottom of the water collection trough through the slope and is discharged into the collection box through the drain pipe for unified treatment, facilitating drainage and preventing water from accumulating inside the protective box.

[0006] Furthermore, a guide rail is fixedly connected to the bottom of the mounting groove, and a groove is provided at the bottom of the collection box, with the guide rail slidably connected to the inside of the groove.

[0007] Furthermore, the protective box has a sliding groove on its exterior, and a limiting frame is slidably connected inside the sliding groove, with the inner sidewall of the limiting frame fitting against the exterior of the collection box. By setting the guide rail and the limiting frame, the collection box is limited by the guide rail during use, making it easy for the collection box to move inside the installation slot. When the collection box is inside the installation slot, the limiting frame is lowered to limit the collection box, which helps to improve the stability of the collection box installation.

[0008] Furthermore, the inner wall of the protective box is fixedly connected with two locking blocks, which are symmetrically distributed.

[0009] Furthermore, a mounting plate is fixedly connected between the two card blocks, and a power supply is installed on the top of the mounting plate.

[0010] Furthermore, a handle is fixedly connected to the front end of the collection box, and the handle is provided with anti-slip texture.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model is equipped with a support frame, a drainage trough, a water collection trough, a drain pipe, and a collection box. In use, the heating plate is used to heat up the inside of the protective box, thereby defrosting the outside of the air source heat pump body. The frost melts into water and is discharged from the support frame through the drainage trough. It then enters the bottom of the water collection trough through the inclined surface and is discharged into the collection box through the drain pipe for unified treatment, which facilitates drainage and prevents water from accumulating inside the protective box.

[0012] 2. This utility model is equipped with a guide rail and a limiting frame. In use, the guide rail is used to limit the collection box, making it easy for the collection box to move inside the installation slot. When the collection box is inside the installation slot, the limiting frame is moved down to limit the collection box, which helps to improve the stability of the collection box installation.
