Abstract
Description
Technical Field
[0001] The present application relates to the technical field of air energy heat pumps, and in particular to an air energy heat pump structure. Background Art
[0002] An air-source heat pump is a heat conversion device that uses the heat energy in the air for air conditioning and hot water supply. It transfers the heat energy in the low-temperature air to the indoor room or hot water through a reverse thermodynamic cycle to achieve indoor air heating or cooling. It is widely used in industrial production.
[0003] At present, air-to-energy heat pumps are mainly composed of an outdoor unit, an indoor unit and a control system. The outdoor unit is equivalent to a heat exchanger, which draws air in for heat exchange through a fan and extracts heat from the air. The heat is then transmitted to the indoor unit via the refrigerant, and heat exchange is carried out through the heat exchanger to provide hot or cold water to the room. In this process, the control system plays a role in controlling the operation of the entire air-to-energy heat pump. Specifically, it measures indoor and outdoor temperature factors through sensors, and automatically starts and stops various parts of the air-to-energy heat pump to achieve the best heating or cooling effect, which can effectively improve equipment efficiency and reduce energy consumption.
[0004] However, when the equipment is running in winter, the unit will produce a large amount of water flowing on the ground due to water vapor defrosting. If the temperature is below 0 degrees Celsius, the water produced by defrosting on the ground cannot be drained away in time and will freeze the drain pipe, eventually causing the unit to malfunction. At present, it still has great limitations. Utility Model Content
[0005] In order to reduce the possibility of drainage failure in the unit, the present application provides an air-energy heat pump structure.
[0006] The air energy heat pump structure provided in this application adopts the following technical solution:
[0007] An air energy heat pump structure includes a heat pump body and a base, wherein the heat pump body is arranged on the base, a water storage cavity is arranged on the top of the base, and a drain outlet connected to the water storage cavity is arranged through one side of the base; and a cleaning mechanism can be slidably arranged on the base and is used to push condensed water away to the drain outlet.
[0008] By adopting the above technical solution, the base can, on the one hand, play the role of supporting the heat pump body. At the same time, on the other hand, the water storage cavity inside the base can store condensed water. Then, under the push of the cleaning mechanism, the condensed water can be pushed to the drain outlet for discharge, thereby reducing the possibility of water accumulation and avoiding as much as possible the freezing of the drain pipe due to untimely discharge of accumulated water, thereby ultimately reducing the failure rate of the unit.
[0009] Preferably, the cleaning mechanism includes a power unit, which is arranged on the base; a pushing unit, which is located in the water storage cavity and spans across both sides of the water storage cavity, the pushing unit is slidably arranged on the base, and the power unit is connected to the pushing unit, and the power unit is used to drive the pushing unit to be closer to or farther away from the drain outlet to push the accumulated water to the outside of the base.
[0010] By adopting the above technical solution, the power unit can output power to make the pushing unit reciprocate, thereby cleaning the accumulated water to the outside of the base. The structure is reasonably set up and the operation is efficient, and the cleaning efficiency is remarkable.
[0011] Preferably, the push-off portion includes a screw rod rotatably disposed on the base and connected to the power portion, wherein the power portion is used to drive the screw rod to rotate; and a push rod slidably disposed on the base and threadedly connected to the screw rod.
[0012] By adopting the above technical solution, the push rod can be driven to move under the rotation of the screw rod, and the push rod can push the accumulated water away from the base to play a role in drainage, and the action is quick and efficient.
[0013] Preferably, there are two screw rods, which are respectively distributed at two ends of the push rod. The cleaning mechanism also includes a linkage part, and the power part is connected to the two groups of screw rods via the linkage part.
[0014] By adopting the above technical solution, due to the long length of the push rod, if only one set of screw rod structure is used, it is easy to cause the push rod to be overloaded, thereby causing structural deformation. Based on this, by setting two sets of screw rods and arranging the two sets of screw rods at both ends of the push rod, under the diversion effect of the linkage part, the two sets of screw rods can be driven to start at the same time, thereby applying uniform thrust to the push rod, and the structural stability is significantly improved.
[0015] Preferably, a cutting edge is provided on the side of the push rod facing the drain outlet, and the cutting edge is in close contact with the surface of the base.
[0016] By adopting the above technical solution, if condensed water freezes in extreme environments, the frost can be scraped off through the blade edge, which is conducive to removing the frost and further optimizes and improves the practicality of the structure.
[0017] Preferably, a first heating portion is embedded in the cutting edge.
[0018] By adopting the above technical solution, the first heating part can heat the cutting edge so that the cutting edge can more easily scrape off frosted ice cubes, and the effect is significant.
[0019] Preferably, a second heating unit is embedded in the base.
[0020] By adopting the above technical solution, the second heating part can heat the base, thereby reducing the adhesion between the ice cubes and the base, which is beneficial for scraping off the ice cubes through the cleaning mechanism, and the deicing effect is significant.
[0021] Preferably, the second heating part comprises a temperature controller; and second heating wires, and the second heating wires are evenly arranged on the base.
[0022] By adopting the above technical solution, the thermostat plays a role in adjusting the heating temperature and heating time of the second heating wire, which is more intelligent and convenient to use. At this time, under the action of the second heating wire, the base can be heated evenly so that the cleaning mechanism can remove ice in a larger area.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. The base carries the heat pump body. At this time, the water storage chamber inside the base can store condensed water. Then, under the driving action of the cleaning mechanism, the condensed water can be pushed away to the drain outlet for discharge, reducing the possibility of water accumulation and avoiding the freezing of the drain pipe due to untimely discharge of accumulated water as much as possible, and finally reducing the failure rate of the unit;
[0025] 2. By setting two sets of screw rods and arranging the two sets of screw rods at both ends of the push rod, under the diversion effect of the linkage part, the two sets of screw rods can be driven to start at the same time, thereby applying uniform thrust to the push rod, and the structure is stable;
[0026] 3. The first heating part and the second heating part cooperate with each other to melt the ice on the base, which is conducive to rapid defrosting and has a significant deicing effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0031] The following is combined with Figure 1-3 This application is described in further detail.
[0032] The embodiment of the present application discloses an air energy heat pump structure.
[0033] Reference Figure 1 and Figure 2 The structure includes a heat pump body 1, wherein the heat pump body 1 mainly refers to the external unit part of the heat pump system. During installation, the heat pump body 1 is usually fixedly installed on a building. During the operation of the heat pump body 1, condensed water will be generated, and the condensed water will flow to the bottom of the heat pump body 1. If the temperature is lower than 0 degrees Celsius, the condensed water accumulated under the heat pump body 1 may block the drain pipe.
[0034] Based on this, the structure also includes a base 2 and a cleaning mechanism 3. In this embodiment, the base 2 is a plate-like structure, and the base 2 is fixedly installed on the building by expansion screws; the heat pump body 1 is fixedly installed on the top of the base 2, and a water storage chamber 4 is recessed on the top of the base 2, and condensed water can flow into the water storage chamber 4; at the same time, a drain port 5 connected to the water storage chamber 4 is provided on one side of the base 2, and the drain port 5 extends from one side of the base 2 to the opposite side to obtain a larger discharge space. In addition, the cleaning mechanism 3 can be slidably arranged on the base 2, and push the condensed water away to the drain port 5 to discharge the accumulated water and reduce the possibility of ice blockage of the accumulated water.
[0035] Reference Figure 2 and Figure 3 Specifically, the cleaning mechanism 3 includes a power unit 31, a linkage unit 32 and a push-off unit 33, wherein the power unit 31 is used to output torque. Specifically, in this embodiment, the power unit 31 uses a motor element to provide a stable power output. The linkage unit 32 is respectively connected to the push-off unit 33 and the power unit 31, and is used to distribute power to the push-off unit 33, so as to clean the accumulated water through the push-off unit 33.
[0036] Among them, the pushing-away part 33 includes a screw rod 331 and a push rod 332. The length direction of the push rod 332 is consistent with the extension direction of the drain outlet 5, and on both sides of the inner edge of the base 2, there are recessed grooves for the push rod 332 to be embedded. The two ends of the push rod 332 are respectively slidably arranged in the two sets of grooves, and the bottom of the push rod 332 is tightly attached to the base 2. At this time, the pushing-away part 33 is located in the water storage chamber 4 and spans both sides of the water storage chamber 4 to clear the accumulated water.
[0037] At the same time, the screw rod 331 is rotatably arranged on the base 2, and a threaded hole is penetrated on the push rod 332. The screw rod 331 is threadedly connected with the push rod 332 via the threaded hole. At this time, the push rod 332 is driven to rotate, which can drive the push rod 332 to slide back and forth on the base 2, thereby pushing the accumulated water in the water storage chamber 4 to the drain port 5, and then draining it to the outside of the base 2 through the drain port 5. Among them, in order to make the push rod 332 obtain uniform thrust, in this embodiment, the number of screw rods 331 is two groups, and they are respectively distributed at the two ends of the push rod 332. At this time, the two screw rods 331 are connected to the power part 31 via the linkage part 32. The linkage part 32 plays the role of distributing power, so that the two screw rods 331 operate synchronously, providing uniform thrust to the two ends of the push rod 332.
[0038] Continue to refer to Figure 2 and Figure 3 In order to evenly distribute the power to the two sets of screw rods 331, the linkage part 32 group includes a linkage shaft 321 and a bevel gear set 322. The linkage shaft 321 is rotatably arranged on the base 2 and close to the ends of the two screw rods 331. The number of bevel gear sets 322 matches the number of screw rods 331. The two bevel gears are fixedly arranged on the linkage shaft 321 and the screw rod 331 respectively, and the linkage shaft 321 is fixedly connected to the output of the power part 31 through a coupling. At this time, starting the power part 31 can drive the linkage shaft 321 to rotate, and under the drive of the bevel gear set 322, the power is distributed to the screw rod 331, so that the screw rod 331 rotates.
[0039] Furthermore, if the accumulated water freezes in the base 2, the push rod 332 may encounter relatively large resistance. In order to reduce the difficulty of removing the frost, a cutting edge 8 is integrally connected to the side of the push rod 332 facing the drain port 5, and the cutting edge 8 is closely attached to the surface of the base 2. Based on the above arrangement, the cutting edge 8 can be used to scrape the frost, the resistance encountered by the push rod 332 is reduced, and the scraping action is more reliable.
[0040] In addition, if the weather is extremely cold, the push rod 332 may not move smoothly. Based on this, in order to further optimize the frost removal effect, a first heating part 6 is firstly buried in the cutting edge 8. Specifically, the first heating part 6 includes a first heating wire 61 and a thermostat 62. The first heating wire 61 is connected to the thermostat 62, and the first heating wire 61 is buried in the cutting edge 8 along the length direction of the push rod 332. At this time, the first heating wire 61 can be heated by the thermostat, and then the cutting edge 8 is further heated, so that the cutting edge 8 can more easily remove the frosted ice, and the effect is significant.
[0041] On the other hand, the second heating part 7 can also be embedded in the base 2 at the same time. The structure of the second heating part 7 is similar to that of the first heating part 6. The second heating part 7 includes a second heating wire 71 and a thermostat 62. The first heating part 6 and the second heating part 7 can share the same thermostat 62. The principle thereof will not be described in detail here. The second heating wire 71 is connected to the thermostat 62, and in this embodiment, the second heating wire 71 is arranged in a U-shaped structure at the base 2. Such an arrangement can evenly heat the base 2, so that the cleaning mechanism 3 can remove ice cubes in a larger area.
[0042] The implementation principle of an air-source heat pump structure in an embodiment of the present application is as follows: the condensed water generated by the heat pump body 1 can flow into the water storage chamber 4 inside the base 2 for storage, and then, under the pushing action of the cleaning mechanism 3, the condensed water can be pushed away to the drain outlet 5 for discharge, thereby reducing the possibility of water accumulation and avoiding as much as possible the freezing of the drain pipe due to untimely discharge of accumulated water, thereby ultimately reducing the failure rate of the unit.
[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
