[0021] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0022] See also Figure 1-4 The utility model provides a technical solution, an intelligent defrosting air source heat pump outdoor unit.

[0023] Example:

[0024] Please refer to the attached Figure 1-4 In a specific implementation process, an intelligent defrosting air source heat pump outdoor unit includes a heat pump body 13, an upper cover 1, two ventilation side panels 3, two vertical panels 16, a base 6, a heater 12, a temperature sensor 10, an automatic lifting structure, and an exhaust structure. The heat pump body 13 is installed on the base 6, the two ventilation side panels 3 are symmetrically installed on the left and right sides of the upper end surface of the base 6, the two vertical panels 16 are symmetrically installed on the front and back sides of the upper end surface of the base 6, the heater 12 is installed on the vertical panels 16, the automatic lifting structure is installed on the ventilation side panels 3, the exhaust structure is installed on the inner wall of the upper cover 1, the temperature sensor 10 is installed on the exhaust structure, and the automatic lifting structure includes four pull rod modules 5, four connecting plates 15, two telescopic sleeves 4 and two telescopic plates 14;

[0025] A group consists of two connecting plates 15, two tie rod modules 5, a telescopic sleeve 4 and a telescopic plate 14, which are divided into two groups. The two groups are symmetrically installed on a ventilation side panel 3 on the left and right sides respectively. The two tie rod modules 5 of each group are symmetrically installed on the left and right sides of the vertical plate 16. The bottom ends of the two tie rod modules 5 of each group are fixedly installed on the base 6. One end of the two connecting plates 15 of each group is respectively installed on the two tie rod modules 5 of each group, and the other end is installed on the telescopic plate 14. Each group of telescopic plates 14 is installed in the telescopic sleeve 4 and the inner surface is in contact with the ventilation side panel 3. Each group of telescopic sleeves 4 is installed on the ventilation side panel 3.

[0026] It should be noted that the outdoor unit of the air source heat pump unit is usually placed outdoors. If the outside temperature is too low, the equipment will be frosted. If it is not handled in time, it will seriously affect the use, so a defrosting device is needed. In this case, if the temperature sensor 10 senses that the temperature is too low, it will control the motor in the pull rod module 5 to start. After the motor is started, it will drive the threaded rod connected to it to rotate, and the slider on the threaded rod will move downward with the rotation. Since the two ends of the connecting plate 15 are connected to the slider and the telescopic plate 14, the telescopic plate 14 also moves downward through the connecting plate 15 until the telescopic plate 14 completely blocks the vent of the ventilation side panel 3. At this time, the heater 12 is started, and as the internal temperature rises, the frost on the heat pump body 13 melts away. As the temperature rises, the temperature sensor 10 will control the pull rod module 5 to control the telescopic plate 14 to move upward to open the vent, and the temperature sensor 10 will control the exhaust structure to operate to accelerate the discharge of high-humidity gas inside.

[0027] In the specific implementation process, the exhaust structure includes an electric drive 7, a rotating shaft 8, a fan 11, a fixing seat 9 and a support plate 2;

[0028] The support plate 2 is fixedly installed between the ventilation side plates 3 on the left and right sides, the bottom end of the electric driver 7 is fixedly installed on the inner wall of the upper cover 1, the fixed seat 9 is installed on the support plate 2, one end of the rotating shaft 8 is installed on the electric driver 7 and the other end is installed with a fan 11, and the middle of the rotating shaft 8 passes through the fixed seat 9 and the support plate 2.

[0029] It should be noted that the temperature sensor 10 controls the electric driver 7 to rotate, the electric driver 7 drives the rotating shaft 8 to rotate, and the rotating shaft 8 drives the fan 11 connected thereto to rotate, thereby realizing internal air circulation and accelerating the discharge of high-humidity air.

[0030] In the specific implementation process, an annular groove is cut around the base 6 where it is installed with the heat pump body 13, and a drainage hole is provided on the inner wall of the annular groove, which is obliquely connected to the outer wall of the base 6.

[0031] It should be noted that when the internal heating is performed and defrosting occurs, water vapor and water droplets will be formed, and the water droplets will fall and gather in the annular groove on the base 6. The water can be drained to the outside through the drainage holes on the annular groove to ensure that no water flow will gather inside and prevent frost from forming again.

[0032] During the specific implementation process, various parts inside the box should be made of stainless steel.

[0033] It should be noted that high air humidity during internal heating can easily cause corrosion and rust. Stainless steel can better prevent equipment from rusting and aging.

[0034] In the specific implementation process, ventilation holes should be provided on the left and right ventilation side panels 3 in the space where the electric drive 7 is installed.

[0035] It should be noted that the electric drive 7 generates heat when in operation, and the support plate 2 isolates the electric drive 7 from the space of the equipment below. Therefore, ventilation holes need to be opened on the left and right ventilation side panels 3 to ensure the temperature stability of the space.

[0036] In a specific implementation process, the connecting plate 15 and the telescopic plate 14 are connected by threads.

[0037] It should be noted that the threaded connection can make the connecting plate 15 and the telescopic plate 14 more stable.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art 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 appended claims and their equivalents.
