Description

Technical Field

[0001] This utility model relates to the field of heat pump technology, and in particular to a centralized drainage structure for heat pumps. Background Technology

[0002] The centralized drainage structure of a heat pump is mainly designed to solve the problem of condensate drainage during equipment operation, ensuring stable and efficient operation of the equipment. It guarantees that the condensate generated during heat pump operation can be effectively and safely disposed of, thereby ensuring the normal operation and service life of the equipment.

[0003] In the prior art (Chinese invention patent application No. 202323533592.7, entitled "A Centralized Drainage Structure for a Heat Pump"), the technical solution relates to the field of heat pump equipment technology, including a drain tank. A drain pipe is fixedly connected to the lower right end of the drain tank, and a drain mechanism is fixedly connected to the upper end of the inner wall of the drain tank. Two clamping mechanisms are movably connected to the left and right sides of the top of the drain tank. The drain mechanism includes a drain plate, and the left and right sides of the drain plate are fixedly connected to the left and right sides of the upper end of the inner wall of the drain tank. The centralized drainage structure for a heat pump described in this technical solution allows the two clamping blocks to move inward by rotating two rockers, thereby installing the entire structure at the bottom of the heat pump. With the addition of a soft pad, pressure is applied, increasing the friction between the structure and the heat pump, preventing the heat pump from moving. This allows for quick and convenient installation or disassembly of the structure and the heat pump, resulting in better drainage. In implementing this technical solution, the inventors discovered at least the following problems in the prior art:

[0004] Most existing drainage systems rely on the natural flow of liquid under gravity for discharge, lacking effective auxiliary guidance or cleaning functions. This causes liquid to easily stagnate in baffles, channels, and other parts during flow, leading to scale and impurity deposits. Over time, these residues not only affect drainage efficiency but can also cause blockages, reducing the stability and safety of equipment operation.

[0005] Furthermore, before liquids enter the collection tank, they typically need to be filtered through a filter to remove impurities such as oil and particulate matter. However, most current drainage systems use integrated, built-in filters that are fixed inside the drainage structure and difficult to remove individually. This often requires users to disassemble the entire drainage assembly, or even part of the heat pump unit, to clean the filter, resulting in cumbersome, time-consuming, and labor-intensive operations, low maintenance efficiency, increased labor costs, and greater difficulty in use. Utility Model Content

[0006] The purpose of this invention is to provide a centralized drainage structure for heat pumps, which avoids the problems of existing drainage structures that rely heavily on gravity for natural drainage, lack auxiliary flow guidance and cleaning functions, and are prone to scale and impurity deposits in the guide plates and channels, affecting drainage efficiency and causing blockages. Furthermore, the filters are mostly built-in integrated designs, making them difficult to disassemble and clean individually. Maintenance requires complete disassembly of the device, which is complex, time-consuming, and labor-intensive, reducing ease of use and maintenance efficiency.

[0007] This utility model provides a centralized drainage structure for a heat pump, including a water collection tank. The inner cavity of the water collection tank is provided with a flow guiding component. The flow guiding component includes a fixing plate. The top of the fixing plate is fixedly connected to the flow guiding plate. A heating component is installed at the bottom of the flow guiding plate. The front and rear sides of the flow guiding plate are fixedly connected to the front and rear sides of the inner cavity of the water collection tank. The left and right sides of the inner cavity of the fixing plate are provided with interception components. The interception components include a filter screen and a positioning box.

[0008] In one specific implementation, protective boxes are provided on the top of both the front and rear sides of the guide plate, and the inner cavity of the protective box is rotatably connected to a first threaded rod.

[0009] In one specific implementation, the surface of the first threaded rod is threadedly connected to two first threaded plates arranged symmetrically from left to right, and the surface of the first threaded plates is slidably connected to the inner cavity of the protective box.

[0010] In one specific implementation, a connecting rod is fixedly connected to the bottom of the first threaded plate, and a first scraper is fixedly connected to the bottom end of the connecting rod.

[0011] In one specific implementation, several push rods are fixedly connected to both the left and right sides of the first scraper surface, and a second scraper is fixedly connected to the end of each push rod away from the first scraper.

[0012] In one specific implementation, mounting boxes are fixedly connected to both the left and right sides of the water collection tank, and a motor is fixedly connected to the inner cavity of the mounting box. The output shaft of the motor is fixedly connected to the right end of the first threaded rod.

[0013] In one specific implementation, the inner cavity of the positioning box is rotatably connected to a second threaded rod, and a rotating rod is provided through the front side of the inner cavity of the positioning box.

[0014] In one specific implementation, the rear end of the rotating rod and the surface of the second threaded rod are respectively fixedly connected to two meshing bevel gears, and the surface of the second threaded rod is threadedly connected to two second threaded plates arranged symmetrically from left to right.

[0015] In one specific implementation, a long rod is fixedly connected to one side of the two second threaded plates facing away from each other, and the end of the long rod away from the second threaded plates is fixedly connected to the surface of the filter screen plate.

[0016] In one specific implementation, two cleaning rollers arranged symmetrically on the left and right sides of the water collection tank are rotatably connected, and two meshing gears are fixedly connected to the surfaces of the two cleaning rollers. A toothed plate that meshes with the gears is fixedly connected to the surface of the second threaded plate.

[0017] The beneficial effects of this application are: the combined use of the flow guiding component and the interception component effectively improves the smoothness and cleanliness of the heat pump drainage process. The flow guiding component plays an active guiding role in the liquid discharge process, accelerating the liquid flow rate and significantly reducing or even avoiding liquid stagnation in the flow guiding structure, thereby preventing scale buildup and clogging problems.

[0018] Meanwhile, the filter in the interceptor assembly effectively filters out impurities such as oil and particulate matter carried in the liquid, improving drainage quality and protecting the subsequent drainage system from contamination or damage. For easy maintenance, the interceptor assembly features a detachable design. After a period of use, the filter can be removed from the drainage structure for cleaning or replacement without disassembling the entire drainage device or heat pump equipment, greatly simplifying the maintenance process and saving time and labor costs.

[0032] Existing drainage structures mostly rely on gravity for natural drainage, lacking auxiliary flow guidance and cleaning functions. This easily leads to scale and impurity buildup in the guide plates and channels, affecting drainage efficiency and causing blockages. Furthermore, filters are often integrated, making them difficult to disassemble and clean individually. Maintenance requires complete disassembly of the entire device, which is complex, time-consuming, and labor-intensive, reducing ease of use and maintenance efficiency. Therefore, the inventors have developed a centralized drainage structure for heat pumps. Through the coordinated work of flow guidance and interception components, the smoothness and cleanliness of heat pump drainage are effectively improved. The flow guidance component accelerates liquid flow, preventing scale and blockages caused by stagnation; the filter in the interception component filters impurities and can be disassembled and cleaned individually, making maintenance convenient and efficient, thus solving the aforementioned shortcomings.

[0033] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] Please refer to Figures 1 to 11This utility model embodiment provides a centralized drainage structure for a heat pump, including a water collection tank 1. The inner cavity of the water collection tank 1 is provided with a flow guiding component 2. Water outlet pipes are connected to both the front and rear sides of the water collection tank 1. The flow guiding component 2 includes a fixing plate 21, whose left and right sides are fixedly connected to the left and right sides of the inner cavity of the water collection tank 1. A flow guiding plate 22 is fixedly connected to the top of the fixing plate 21, and flow guiding grooves are provided on both the left and right sides of the flow guiding plate 22 to guide the condensate and other liquids generated by the heat pump out. A flow guiding groove is provided at the bottom of the inner cavity of the water collection tank 1. The water collection chamber is located at the bottom of the fixed plate 21, and a heating element 23 is installed at the bottom of the guide plate 22. The heating element 23 is a heating device such as a heating coil, which prevents the liquid from freezing and stagnating on the guide plate 22 and speeds up the drainage process. The heating element 23 is in close contact with the guide plate 22 and the guide channel. This contact means that the heating element 23 is installed on the inner side of the guide plate 22 to form a close fit. The front and rear sides of the guide plate 22 are fixedly connected to the front and rear sides of the inner cavity of the water collection tank 1.

[0035] Please refer to Figures 2 to 11The left and right sides of the inner cavity of the fixed plate 21 are provided with interception components 3.

The left and right sides of the filter screen plate 31 are slidably connected to the left and right sides of the inner cavity of the fixed plate 21. The top of the fixed plate 21 has an open mouth body, which facilitates the filtering effect of liquid passing through the filter screen plate 31 to intercept impurities. The surface of the positioning box 32 is fixedly connected to the surface of the water collection tank 1. The filter screen plate 31 is installed at the center of the inner cavity of the fixed plate 21, so that the filter screen plate 31 and the fixed plate 21 form a height difference, thereby storing oil, particles and other impurities. The top of the front and rear sides of the guide plate 22 Each is equipped with a protective box 24, and the surface of the protective box 24 is fixedly connected to the front and rear sides of the inner cavity of the water collection tank 1. An inclined plate is fixedly connected to the top of the protective box 24, allowing the liquid discharged from the heat pump to fall through the inclined plate and be discharged into the guide plate 22. A first threaded rod 25 is rotatably connected to the inner cavity of the protective box 24, and the surface of the first threaded rod 25 has two symmetrically arranged external threads. The first threaded rod 25 is treated for corrosion and moisture resistance. Two first threaded plates 26 are symmetrically arranged on the surface of the first threaded rod 25, and the surfaces of the first threaded plates 26 are slidably connected to the inner cavity of the protective box 24. The surface of the threaded plate 26 is slidably connected to the inner cavity of the protective box 24. A connecting rod 27 is fixedly connected to the bottom of the first threaded plate 26, and a fixed cavity that moves with the connecting rod 27 is opened at the bottom of the protective box 24. A first scraper 28 is fixedly connected to the bottom end of the connecting rod 27. Several push rods 29 are fixedly connected to both sides of the surface of the first scraper 28. A second scraper 210 is fixedly connected to the end of the push rod 29 away from the first scraper 28. The first scraper 28 is in contact with the surface of the guide plate 22, while the bottom of the second scraper 210 is in contact with the guide groove in the guide plate 22, thereby accelerating the cleaning of the liquid retained on the guide plate 22. To prevent scale formation, mounting boxes 211 are fixedly connected to both sides of the water collection tank 1. A motor 212 is fixedly connected to the inner cavity of the mounting box 211. The top of the mounting box 211 is connected to the heat pump for centralized drainage. The output shaft of the motor 212 is fixedly connected to the right end of the first threaded rod 25. A second threaded rod 33 is rotatably connected to the inner cavity of the positioning box 32. The surface of the second threaded rod 33 has two opposite external threads. A rotating rod 34 is inserted through the front of the inner cavity of the positioning box 32. The area of ​​contact between the rotating rod 34 and the positioning box 32 is rotatably connected by a bearing.

[0036] Please refer to Figures 3 to 11The rear end of the rotating rod 34 and the surface of the second threaded rod 33 are respectively fixedly connected to two meshing bevel gears 35, and the front end of the rotating rod 34 is fixedly connected to a handwheel for easy rotation by the user. The surface of the second threaded rod 33 is threadedly connected to two second threaded plates 36 arranged symmetrically on the left and right, and the rear side of the second threaded plates 36 is slidably connected to the inner cavity of the positioning box 32. A long rod 37 is fixedly connected to the opposite side of the two second threaded plates 36. The end of the long rod 37 away from the second threaded plates 36 is fixedly connected to the surface of the filter screen plate 31, and one side of the filter screen plate 31 extends through to the outside of the water collection tank 1. The area where the filter screen 31 contacts the water collection tank 1 is sealed, for example by adding sealing gaskets or sealing strips. Two cleaning rollers 310 are rotatably connected to both sides of the water collection tank 1 and are arranged symmetrically. Two meshing gears 39 are fixedly connected to the surface of the two cleaning rollers 310. A toothed plate 38 that meshes with the gears 39 is fixedly connected to the surface of the second threaded plate 36. The positioning box 32 has a positioning cavity that moves with the toothed plate 38 and the long rod 37. The opposite side of the other two cleaning rollers 310 is used in conjunction with the top and bottom of the filter screen 31.

[0037] Specifically, when the heat pump discharges condensate into the water collection tank 1, the liquid is diverted to the left and right sides through the guide plate 22 and the guide channel. During this process, the heating component 23 heats the liquid remaining in the guide plate 22 and the guide channel, effectively preventing the liquid from freezing on the guide plate 22 and the guide channel in low-temperature environments. Simultaneously with heating, the motor 212 is activated, driving the first threaded rod 25 to rotate. According to the threaded transmission principle, the first threaded rod 25 pushes the connecting rod 27 to move, and the connecting rod 27 further drives the first scraper 28, the push rod 29, and the second scraper 210 to move synchronously. The first scraper 28 and the second scraper 210 clean the surface of the guide plate 22 and the guide channel, removing residual liquid and scale, thereby accelerating the liquid flow and smoothly discharging it into the bottom of the water collection tank 1. Before entering the water collection tank 1, the liquid needs to be filtered through the filter screens 31 installed on both sides to remove impurities such as oil.

[0038] To facilitate subsequent maintenance and cleaning of the filter screen 31, a manually operable cleaning mechanism is provided: the user can manually rotate the rotating rod 34, which drives the bevel gear 35 to rotate. The bevel gear 35 engages with the second threaded rod 33, causing it to rotate synchronously. The second threaded rod 33 drives two second threaded plates 36 to move left and right, and the second threaded plates 36 drive the long rod 37 and the toothed plate 38 to move synchronously. During the movement, the toothed plate 38 meshes with the gear 39, driving the cleaning roller 310 to rotate, thus achieving the cleaning function of the filter screen 31 during the movement. At this time, the filter screen 31 can be removed separately from the inner cavity of the water collection tank 1 without the need for complete disassembly of the water collection tank 1 or the heat pump body, greatly improving maintenance efficiency and ease of use.

[0039] In summary, the working principle of a centralized drainage structure for a heat pump according to this utility model embodiment is as follows: First, the condensate discharged by the heat pump is diverted to both sides through the guide plate 22 and the guide channel. The heating component 23 can prevent freezing at low temperatures. The motor 212 drives the scraper assembly to clean the guide structure and avoid scale buildup. After being filtered by the filter screen 31, the liquid enters the water collection tank 1. During cleaning, simply rotate the rotating rod 34 to drive the cleaning roller 310 to rotate, and the filter screen 31 can be removed separately for cleaning without disassembling the entire device, making maintenance convenient and efficient.
