Description

Technical Field

[0001] This utility model belongs to the technical field of air source heat pump units, and particularly relates to an air source heat pump unit with auxiliary drainage. Background Technology

[0002] An air source heat pump unit consists of four main components: an evaporator, a condenser, a compressor, and an expansion valve, forming a closed system. An air source heat pump is a device that uses heat from the ambient air for cooling or heating.

[0003] For example, patent CN215260667U discloses a defrosting and drainage device for low-ambient-temperature air-source heat pump units. The device includes a base, column, drain pipe, drain trough, finned heat exchanger support plate, and heating device. The base, column, and finned heat exchanger support plate are connected sequentially from bottom to top. The drain trough is fixed below the finned heat exchanger support plate, and the drain pipe is fixedly connected to the drain outlet of the drain trough. The heating device includes an electrical control system and an electric heating element, which is installed inside the drain trough and drain pipe and extends to the end of the drain pipe. By combining a sheet metal structure with a low-energy-consumption electric heating element, the problem of finned icing in low-ambient-temperature air-source heat pumps can be solved, thus resolving the issue of finned heat exchanger icing causing the unit to malfunction during winter operation. The electrical control system activates the electric heating element based on the defrosting and drainage status, avoiding increased energy consumption when the heating element is activated without frost or drainage. The defrosting and drainage process can be completed automatically without human intervention.

[0004] Existing air source heat pump units with auxiliary drainage often experience water droplets accumulating within the unit due to the inability to drain them promptly. Therefore, we propose an air source heat pump unit with auxiliary drainage capabilities. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing an air-source heat pump unit that can assist in drainage, thus avoiding the problem of water droplets not being discharged in a timely manner.

[0006] In view of this, the present invention provides an air source heat pump unit with auxiliary drainage, including a working frame, a drainage frame at the top of the working frame, an exchange frame fixedly connected to the top of the drainage frame, a compressor fixedly connected to the inner wall of the working frame, an evaporator connected to the output end of the compressor through an internal pipe extending into the working frame, an expansion valve connected to one end of the evaporator, a condenser connected to one end of the expansion valve, a collection trough on the inner wall of the drainage frame, a drainage channel fixedly connected to the bottom of the collection trough, a drain outlet fixedly connected to one end of the drainage channel, a mounting spring screwed onto the inner wall of the drainage frame, a sliding plate screwed onto one end of the mounting spring, a push handle fixedly connected to the outer wall of the sliding plate, an installation frame fixedly connected to the bottom of the sliding plate, a replacement groove provided at the connection between the drainage frame and the installation frame, and a filter screen fixedly connected to the outer wall of the installation frame.

[0007] Based on the above structure, water droplets fall into the collection groove in the drainage frame. The inverted triangular collection groove facilitates the smooth flow of water droplets into the drainage groove, and they are discharged from the drain outlet through the filter screen. The filter screen will accumulate a lot of dust after working for a long time and needs to be replaced. The staff pushes the handle, which causes the installation spring to drive the sliding plate to slide through its own elasticity. The sliding plate drives the installation frame to slide along the groove of the replacement slide, thereby quickly replacing the filter screen inside the installation frame.

[0008] Preferably, the cross-section of the drainage trough is an inverted triangle. In this embodiment, the inverted triangle collection trough helps water droplets flow smoothly into the drainage trough and avoids water droplet accumulation.

[0009] Preferably, the mounting frame forms a sliding structure with the replacement groove via a mounting spring and a sliding plate. The mounting frame is sealed to the drain outlet. In this embodiment, it is convenient for the operator to turn the push handle so that the mounting spring drives the sliding plate to slide through its own elasticity. The sliding plate drives the mounting frame to slide along the groove of the replacement groove, thereby quickly replacing the filter screen inside the mounting frame.

[0010] Preferably, the filter screen is provided in two sets, and the mounting frame and the filter screen are detachable. In this embodiment, by providing two sets of filter screens, it is beneficial to quickly replace the filter screens.

[0011] Preferably, the outer wall of the exchange frame is provided with a screw, and the outer wall of the screw is threadedly connected to a threaded slider. Both ends of the threaded slider are screwed with connecting rods, and the bottom end of the connecting rod is screwed with a sliding frame. A limiting groove is formed at the connection between the exchange frame and the sliding frame. A scraper is fixedly connected to the outer wall of the sliding frame, and the bottom end of the scraper is slidably connected to a drainage grid fixedly connected to the bottom end of the exchange frame. In this embodiment, the rotation of the screw drives the threaded slider to slide through the thread. The sliding of the threaded slider drives the sliding frame to slide along the groove of the limiting groove through the connecting rod. The sliding of the sliding frame drives the scraper to slide along the outer wall of the drainage grid, thereby cleaning the drainage grid and preventing the drainage grid from becoming blocked, which would prevent normal drainage.

[0012] Preferably, the scraper is comb-shaped. In this embodiment, it facilitates the sliding frame to slide the scraper along the outer wall of the drainage grid, thereby cleaning the drainage grid and preventing it from becoming clogged.

[0013] Preferably, the drainage grid is distributed in equidistant strips along the bottom end of the exchange frame. In this embodiment, this facilitates water droplets falling into the drainage frame through the drainage grid.

[0014] The beneficial effects of this utility model are:

[0015] 1. This air source heat pump unit with auxiliary drainage has a collection tank. Water droplets fall into the collection tank in the drainage frame. The inverted triangular collection tank facilitates the smooth flow of water droplets into the drainage tank and out of the drain through the filter screen. The filter screen will accumulate a lot of dust after long-term operation and needs to be replaced. The operator moves the push handle, which causes the installation spring to drive the sliding plate to slide. The sliding plate drives the installation frame to slide along the groove of the replacement slide, thereby quickly replacing the filter screen inside the installation frame.

[0016] 2. This air source heat pump unit with auxiliary drainage, by setting up a scraper and a drainage grid, the rotation of the screw drives the threaded slider to slide through the thread, the sliding slider drives the sliding frame to slide along the groove of the limiting groove through the connecting rod, and the sliding frame drives the scraper to slide along the outer wall of the drainage grid, thereby cleaning the drainage grid and preventing the drainage grid from becoming blocked, which would prevent normal drainage.

[0023] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0024] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0025] This application discloses an air source heat pump unit with auxiliary drainage, including a working frame 1, a drainage frame 2 at the top of the working frame 1, an exchange frame 3 fixedly connected to the top of the drainage frame 2, a compressor 4 fixedly connected to the inner wall of the working frame 1, an evaporator 5 connected to the output end of the compressor 4 through a pipe extending into the inner wall of the working frame 1, an expansion valve 6 connected to one end of the evaporator 5, a condenser 7 connected to one end of the expansion valve 6, a collection trough 8 on the inner wall of the drainage frame 2, a drainage trough 9 fixedly connected to the bottom of the collection trough 8, a drain outlet 10 fixedly connected to one end of the drainage trough 9, a mounting spring 11 screwed onto the inner wall of the drainage frame 2, a sliding plate 12 screwed onto one end of the mounting spring 11, a push handle 13 fixedly connected to the outer wall of the sliding plate 12, an installation frame 14 fixedly connected to the bottom of the sliding plate 12, a replacement groove 15 provided at the connection between the drainage frame 2 and the installation frame 14, and a filter screen 16 fixedly connected to the outer wall of the installation frame 14.

[0026] Based on the above structure, water droplets fall into the collection trough 8 in the drainage frame 2. The inverted triangular collection trough 8 facilitates the smooth flow of water droplets into the drainage trough 9, and they are discharged from the drain outlet 10 through the filter screen 16. The filter screen 16 will accumulate a lot of dust after long-term operation, and it needs to be replaced. The operator moves the push handle 13, which causes the mounting spring 11 to drive the sliding plate 12 to slide through its own elasticity. The sliding plate 12 drives the mounting frame 14 to slide along the groove of the replacement slide 15, thereby quickly replacing the filter screen 16 inside the mounting frame 14.

[0027] In one embodiment, the cross-section of the drainage channel 9 is inverted triangular.

[0028] In this embodiment, the inverted triangular collection groove 8 facilitates the smooth flow of water droplets into the drainage groove 9, preventing water droplet accumulation.

[0029] In one embodiment, the mounting frame 14 forms a sliding structure with the replacement slide 15 via the mounting spring 11 and the sliding plate 12, and the mounting frame 14 is sealed to the drain outlet 10.

[0030] In this embodiment, it is convenient for the staff to turn the push handle 13 so that the mounting spring 11 drives the sliding plate 12 to slide through its own elasticity. The sliding plate 12 drives the mounting frame 14 to slide along the groove of the replacement slide 15, thereby quickly replacing the filter screen 16 inside the mounting frame 14.

[0031] In one embodiment, the filter 16 is provided in two sets, and the mounting frame 14 and the filter 16 are detachable structures.

[0032] In this embodiment, by setting two sets of filters 16, it is convenient to quickly replace the filters 16.

[0033] In one embodiment, the outer wall of the exchange frame 3 is provided with a screw 17, and the outer wall of the screw 17 is threadedly connected to a threaded slider 18. Both ends of the threaded slider 18 are screwed with connecting rods 19, and the bottom end of the connecting rods 19 is screwed with a sliding frame 20. A limiting groove 21 is provided at the connection between the exchange frame 3 and the sliding frame 20. A scraper 22 is fixedly connected to the outer wall of the sliding frame 20, and the bottom end of the scraper 22 is slidably connected to a drainage grid 23 that is fixedly connected to the bottom end of the exchange frame 3.

[0034] In this embodiment, the screw 17 rotates and drives the threaded slider 18 to slide through the thread. The threaded slider 18 slides and drives the sliding frame 20 to slide along the groove of the limiting groove 21 through the connecting rod 19. The sliding frame 20 drives the scraper 22 to slide along the outer wall of the drainage grid 23, thereby cleaning the drainage grid 23 and preventing the drainage grid 23 from becoming blocked, which would prevent normal drainage.

[0035] In one embodiment, the scraper 22 is shaped like a comb.

[0036] In this embodiment, the sliding frame 20 is slidably driven to slide the scraper 22 along the outer wall of the drainage grid 23, thereby cleaning the drainage grid 23 and preventing the drainage grid 23 from becoming blocked.

[0037] In one embodiment, the drainage grid 23 is distributed in equidistant strips along the bottom end of the exchange frame 3.

[0038] In this embodiment, it is beneficial for water droplets to fall into the drainage frame 2 through the drainage grille 23.

[0039] In this embodiment, the air source heat pump unit with auxiliary drainage operates as follows: First, the liquid medium absorbs heat from the air in the evaporator 5 and evaporates to form steam. Then, it is compressed into a high-temperature, high-pressure gas by the compressor 4 and enters the condenser 7 to condense into a liquid, transferring the absorbed heat to the water that needs heating. After the liquid medium is depressurized and expanded by the expansion valve 6, it returns to the evaporator 5 to absorb heat and evaporate, completing one cycle. This process is repeated, continuously absorbing heat from the low-temperature source and outputting the heated water to directly reach the predetermined temperature.

[0040] Next, the evaporator 5 absorbs heat from the air, causing water molecules in the air to condense into water droplets. The water droplets fall into the drainage frame 2 through the drainage grille 23. Then, the operator rotates the screw 17. The rotation of the screw 17 drives the threaded slider 18 to slide through the thread. The sliding of the threaded slider 18 drives the sliding frame 20 to slide along the groove of the limiting groove 21 through the connecting rod 19. The sliding frame 20 drives the scraper 22 to slide along the outer wall of the drainage grille 23, thereby cleaning the drainage grille 23 and preventing it from becoming blocked, which would prevent normal drainage.

[0041] Finally, the water droplets fall into the collection trough 8 in the drainage frame 2. The inverted triangular collection trough 8 facilitates the smooth flow of the water droplets into the drainage trough 9, and they are discharged from the drain outlet 10 through the filter screen 16. The filter screen 16 will accumulate a lot of dust after working for a long time, so it needs to be replaced. The staff pushes the handle 13, which causes the mounting spring 11 to drive the sliding plate 12 to slide through its own elasticity. The sliding plate 12 drives the mounting frame 14 to slide along the groove of the replacement slide 15, thereby quickly replacing the filter screen 16 inside the mounting frame 14.
