Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heat pumps, and more specifically, to an ice removal unit and a top-outlet heat pump of a top-outlet heat pump. Background Art
[0002] A heat pump is a highly efficient energy-saving device that makes full use of low-grade heat energy. Heat can spontaneously transfer from a high-temperature object to a low-temperature object, but cannot spontaneously proceed in the opposite direction. The working principle of a heat pump is a mechanical device that forces heat to flow from a low-temperature object to a high-temperature object in a reverse cycle manner. It only consumes a small amount of net reverse cycle work and can obtain a large heating capacity, effectively utilizing the difficult-to-apply low-grade heat energy to achieve the purpose of energy conservation. The heat pump unit has no combustible or explosive gases for heating, no electrical heating elements, and high safety; and there is no emission of any waste gas, waste water, or waste residue, which is very environmentally friendly. The average annual operating cost of the heat pump unit is only 1 / 4 of that of direct electric heating, 1 / 3 - 1 / 2 of that of fuel or gas heating, and 1 / 1.5 of that of conventional solar energy.
[0003] For the existing top-outlet heat pump, the air outlet faces upward. When the machine is running, the fan blades rotate, and the heat generated by the machine is discharged through the top air outlet. Since the air outlet of this top-outlet heat pump faces upward, in rainy or snowy weather, rain and snow are likely to enter the air guide ring. If it rains when the ambient temperature is below 0°C, the water hits the top surface of the heat pump and flows down along the edge of the air guide ring into the air inlet. During this process, the water freezes at the edge of the air guide ring. As the rainy or snowy weather continues, the top of the air guide ring accumulates thicker and thicker, covering the entire air guide ring, resulting in the fan blades being damaged and the whole machine malfunctioning. Summary of the Utility Model
[0004] The utility model aims to overcome at least one defect (shortcoming) of the above-mentioned prior art, and provides an ice removal unit and a top-outlet heat pump of a top-outlet heat pump, which can prevent rain and snow from freezing near the air guide ring, avoid damage to the fan blades, and enable the heat pump to operate normally in a low-temperature environment.
[0005] An object of the utility model is to provide an ice removal unit of a top-outlet heat pump, including an air guide plate, the air guide plate is provided with an air guide opening corresponding to the air outlet of the top-outlet heat pump, the air guide opening is connected with a matching air guide ring, and the air guide plate is provided with a first heating structure, and the first heating structure heats at least the air guide plate.
[0006] In this technical solution, the air guiding openings on the air guiding plate are correspondingly arranged at the air outlet of the top-outlet air source heat pump, so that the air discharged from the top-outlet air source heat pump is discharged through the air guiding openings; the shapes and sizes of the air guiding openings and the air guiding ring match each other. For example, when the air guiding opening is circular, the air guiding ring is a cylindrical barrel, and when the air guiding opening is square, the air guiding ring is a square barrel, etc. The air guiding ring plays a role in guiding the air outlet direction. A first heating structure is provided on the air guiding plate, which can heat the air guiding plate to prevent rain and snow on the air guiding plate from freezing in a low-temperature environment, avoiding damage to the fan blades caused by freezing, or performance degradation due to ice and frost blocking the structural channels inside the top-outlet air source heat pump. In this way, the service life of the top-outlet air source heat pump is extended, the maintenance cost is reduced, and the inconvenience and economic losses to users are also avoided. Further, the first heating structure can also heat other structures such as the air guiding ring at the same time, and heat different structures on the de-icing unit at the same time, so that the ice and snow at different positions on the de-icing unit can be fully heated and melted, improving the heating efficiency, so that even in a long-term low-temperature environment, ice and frost accumulation on the top of the top-outlet air source heat pump can be avoided.
[0007] In some embodiments, the air guiding ring protrudes upward from the upper side of the air guiding plate.
[0008] In this technical solution, the protruding direction of the air guiding ring on the air guiding plate is upward. When the rain hitting the air guiding plate or the water melted by the heating structure flows towards the air guiding opening, due to the blocking of the air guiding ring, the water cannot flow into the interior of the top-outlet air source heat pump through the air guiding opening, thus avoiding the negative impact on the operation of the main unit caused by the formation of ice and frost inside the heat pump. Further, in the case of heavy rainfall or snowfall for a long time, there may be some ice and snow that is not melted by the heating structure in time and forms a small amount of accumulation. At this time, due to the blocking of the air guiding ring, the ice and frost will not fall into the interior of the heat pump through the air guiding opening. In this way, the upwardly protruding air guiding ring and the first heating structure cooperate to form a double guarantee for de-icing and frost removal, ensuring that in bad weather, the influence of rain and snow on the internal structure of the heat pump can be avoided, effectively ensuring the normal operation of the top-outlet air source heat pump, reducing the maintenance cost, and optimizing the user experience.
[0009] In some embodiments, a drainage component is further included, and the water on the air guiding plate is discharged through the drainage component.
[0010] In this technical solution, the drainage component is provided to accelerate the drainage speed of the water on the air guiding plate and guide the drainage direction of the water. The setting of the drainage component enables the water on the air guiding plate to be discharged in time without accumulating and overflowing. Instead, the water can be heated and discharged in time, avoiding the accumulation of water on the air guiding plate, reducing the probability of freezing, and at the same time preventing a large amount of water from accumulating to form a humid environment and causing pollution. In addition, the drainage component can guide the drainage direction of the water flow, and through the setting of the drainage component, the water is guided to be discharged in a direction beneficial to the operation of the main unit, preventing the water from flowing down from the air guiding plate and entering the interior of the main unit from other places and causing negative impacts on it.
[0011] In some embodiments, a second heating structure is further included, the drainage assembly includes a drainage hole and a drainage pipe, the drainage hole is provided on the wind guide plate, the drainage pipe is connected to the drainage hole, and the second heating structure heats the drainage pipe.
[0012] In the technical solution, the drain holes can be set at different positions on the wind guide plate. After the water on the wind guide plate enters the drain holes, it flows through the drain pipe and is discharged from the outlet of the drain pipe. The drain pipe can be set under the wind guide plate, and the water can be drained out by simply opening a drain hole on the wind guide plate. In this way, drainage is achieved through a simple structure, making the overall structure of the wind guide plate compact and simple, and convenient for production, transportation and use. In addition, the second heating structure heats the drain pipe to prevent water from freezing in the pipe during the discharge process and blocking the drain pipe, thereby ensuring smooth drainage; it also prevents the water in the drain pipe from freezing and falling into the heat pump and affecting the normal operation of the heat pump.
[0013] In some embodiments, the drainage hole is disposed below the first heating structure, and the first heating structure heats the drainage hole.
[0014] In the present technical solution, the drain hole is arranged below the first heating structure, which can be understood as the first heating structure passing through the surface of the drain hole to heat the water entering the drain hole, so that the water has a relatively high temperature when entering the drain pipe, reducing the possibility of freezing in the drain pipe. The first heating structure and the second heating structure cooperate to form a double protection to prevent the water in the drain pipe from freezing, effectively avoiding the negative impact of freezing of the water in the drain pipe on the operation of the heat pump.
[0015] In some embodiments, the air guide plate is provided with a groove surrounding the air guide port, and the first heating structure and the drainage hole are provided in the groove.
[0016] In the present technical solution, the groove setting can limit the first heating structure, prevent the first heating structure from being displaced due to external factors, and improve its heating stability; and the groove can be set into different shapes according to the position to be heated, such as straight line, curve or square, so as to fix the first heating structure at the position to be heated, so as to facilitate the control of the heating position of the first heating structure. The groove can also play a drainage effect, and the drainage hole is set in the groove, and the water flows along the groove into the drainage hole, thereby improving the drainage efficiency.
[0017] In some embodiments, the groove forms a "匚" and / or a vertically flipped shape of "匚" around the air guide outlet, and at least two drainage holes are provided on the air guide plate.
[0018] In the present technical solution, "匚" and its vertically flipped shape are shapes formed by the extension of the groove, which can be understood as surrounding the air guide port and forming a gap. Compared with only setting the groove on one side of the air guide port, the present solution allows the first heating structure to be distributed in most positions around the air guide port, fully preventing ice or frost from forming at different positions around the air guide port; at the same time, it avoids excessive energy consumption caused by the all-inclusive setting, thereby saving materials and energy. The present solution can accelerate the melting speed due to the shape design of the groove, and the setting of at least two drainage holes can accelerate the drainage speed, thereby avoiding water accumulation.
[0019] In some embodiments, the air guide port is circular, and the distance between two adjacent drainage holes is greater than the diameter of the air guide port.
[0020] In this technical solution, the air guide port is circular, and the air guide ring connected to it is also matched to be cylindrical, so there will be no corners, avoiding the accumulation of frost and the like at the corners. In addition, the design of the circular air guide port and the air guide ring also conforms to the principles of aerodynamics, ensuring that the air is transmitted more evenly and stably. The distance between two adjacent drainage holes is larger than the diameter of the air guide port, ensuring that the two drainage holes are not too close to each other, and the water does not need to flow to the same drainage hole to be discharged, but can flow to the drainage hole close to it, further improving the drainage efficiency.
[0021] In some embodiments, two drainage holes are provided on the air guide plate, and the drainage holes are provided at the corners of the groove, and the corners of the groove are chamfered.
[0022] In this technical solution, when water flows to the corner in the groove, it will flow to the corner and stay there for a while due to the drainage effect of the chamfer. Providing the drainage hole at the corner can further ensure that the water can flow smoothly into the drainage hole for drainage, improve the drainage efficiency, and prevent the water from accumulating in the groove. The chamfer here can be a rounded corner or a chamfered corner.
[0023] Another object of the utility model is to provide a top-outlet air heat pump, wherein any one of the above-mentioned deicing units is provided on the top of the top-outlet air heat pump, and the top-outlet air heat pump also includes a chassis, and a through hole corresponding to the outlet of the drain pipe is provided on the chassis.
[0024] In this technical solution, the outlet of the drain pipe corresponds to the position of the through hole, and the water flows out of the drain pipe and directly discharges out of the heat pump through the through hole of the chassis. At the same time, if there is water on the chassis, it can also be discharged through the through hole. The top-out heat pump equipped with the above-mentioned deicing unit can prevent ice from forming on the top and ensure the normal operation of the heat pump.
[0025] Compared with the prior art, the beneficial effects of the utility model are:
[0026] (1) By providing the first heating structure, the present utility model prevents rain and snow on the air deflector from freezing in a low-temperature environment, avoiding damage to the fan blades caused by freezing or performance degradation due to ice and frost blocking the structural channels inside the top-outlet heat pump. This extends the service life of the top-outlet heat pump, reduces maintenance costs, and also avoids inconvenience and economic losses to users.
[0027] (2) By providing the second heating structure, the present utility model heats the drain pipe to prevent water from freezing inside the pipe during drainage and blocking the drain pipe, ensuring smooth drainage. At the same time, it also prevents the water in the drain pipe from freezing and falling into the interior of the heat pump, affecting the normal operation of the heat pump.
[0028] (3) By providing the upwardly protruding upward air deflector ring, water or ice and frost are blocked from entering the interior of the heat pump through the air deflector opening. Together with the heating structure, it provides double protection, ensuring that in bad weather, the influence of rain and snow on the internal structure of the heat pump can be avoided, effectively ensuring the normal operation of the top-outlet heat pump, reducing maintenance costs, and optimizing the user experience.

[0033] The drawings of the present utility model are only for illustrative purposes and should not be construed as a limitation of the present utility model. For better illustration of the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual size of the product. For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.
[0034] Embodiment 1
[0035] Reference Figure 1 and Figure 2, this embodiment provides an ice removal unit for a top - outlet heat pump, which includes a wind guide plate 100. A wind guide opening corresponding to the air outlet of the top - outlet heat pump is provided on the wind guide plate 100. The wind guide opening is connected to a matching wind guide ring 200. A first heating structure 300 is provided on the wind guide plate 100, and the first heating structure 300 heats at least the wind guide plate 100.
[0036] The wind guide opening on the wind guide plate 100 is correspondingly arranged with the air outlet of the top - outlet heat pump, so that the air discharged from the top - outlet heat pump is discharged through the wind guide opening after leaving the air outlet; the shape and size of the wind guide opening and the wind guide ring 200 are matched. For example, when the wind guide opening is circular, the wind guide ring 200 is a cylindrical barrel, and when the wind guide opening is square, the wind guide ring 200 is a square barrel, etc. The wind guide ring 200 plays a role in guiding the air outlet direction. The first heating structure 300 is provided on the wind guide plate 100, which can heat the wind guide plate 100, prevent rain and snow on the wind guide plate 100 from freezing in a low - temperature environment, avoid damage to the wind blades caused by freezing, or performance degradation due to ice and frost blocking the structural channels inside the top - outlet heat pump. In this way, the service life of the top - outlet heat pump is extended, the maintenance cost is reduced, and the inconvenience and economic losses to users are also avoided. Further, the first heating structure 300 can also heat other structures such as the wind guide ring 200 at the same time, heating different structures on the ice removal unit simultaneously, so that the ice and snow at different positions on the ice removal unit can be fully heated and melted, improving the heating efficiency, and avoiding the accumulation of ice and frost on the top of the top - outlet heat pump even in a long - term low - temperature environment.
[0037] Further, the wind guide ring 200 protrudes upward from the upper side of the wind guide plate 100. Preferably, the height of the upward protrusion of the wind guide ring 200 is 2 - 10 cm. The appropriate size setting ensures that it will not be too low to affect blocking ice and snow from entering the wind guide opening, nor too high to affect the air outlet.
[0038] The protruding direction of the wind guide ring 200 on the wind guide plate 100 is upward. When the rain hitting the wind guide plate 100 or the water melted by the heating structure flows towards the wind guide opening, due to the blocking of the wind guide ring 200, the water cannot flow into the interior of the top - outlet heat pump through the wind guide opening, thus avoiding the negative impact on the operation of the main unit caused by the formation of ice and frost inside the heat pump. Further, in the case of heavy and long - lasting rainfall or snowfall, there may be some ice and snow that are not melted by the heating structure in time and cause a small amount of accumulation. At this time, due to the blocking of the wind guide ring 200, the ice and frost will not fall into the interior of the heat pump through the wind guide opening. In this way, the upward - protruding wind guide ring 200 and the first heating structure 300 cooperate to form a double guarantee for removing ice and frost, ensuring that in bad weather, the influence of rain and snow on the internal structure of the heat pump can be avoided, effectively ensuring the normal operation of the top - outlet heat pump, reducing the maintenance cost, and optimizing the user experience.
[0039] In order to improve the drainage efficiency and guide the drainage direction, a drainage assembly is also provided, and the water on the wind deflector 100 is discharged through the drainage assembly. Preferably, the drainage assembly includes a drainage hole 410 and a drainage pipe 420, wherein the drainage hole 410 is provided on the wind deflector 100, and the drainage pipe 420 is connected to the drainage hole 410.
[0040] In order to improve the heating efficiency, a second heating structure (not shown) is also provided, and the second heating structure heats the drain pipe 420. Furthermore, the drain hole 410 is provided below the first heating structure 300, and the first heating structure 300 heats the drain hole 410, so that when the water flows into the drain hole 410, it is first heated by the first heating structure 300 and then flows into the drain pipe 420.
[0041] The drain hole 410 can be set at different positions on the wind deflector 100, and its shape can be a round hole or a square hole, etc. In this embodiment, the drain hole 410 is a round hole. After the water on the wind deflector 100 enters the drain hole 410, it flows through the drain pipe 420 and then is discharged from the outlet of the drain pipe 420. In this embodiment, the drain pipe 420 is correspondingly set as a round pipe. Compared with the square pipe, the round pipe does not have corners, which prevents frost from accumulating at the corners, and is conducive to smooth drainage in the drain pipe. The drain pipe 420 can be set under the wind deflector 100, and the wind deflector 100 only needs to simply open the drain hole 410 to drain the water. In this way, drainage is achieved through a simple structure, making the overall structure of the wind deflector 100 compact and simple, and convenient for production, transportation and use. In addition, the second heating structure heats the drain pipe 420 to prevent water from freezing in the pipe during the discharge process and blocking the drain pipe 420, thereby ensuring smooth drainage; it also prevents the water in the drain pipe 420 from freezing and falling into the interior of the heat pump and affecting the normal operation of the heat pump.
[0042] In order to guide the water flow and limit the first heating structure 300, the wind guide plate 100 is provided with a groove 110 around the air guide port, and the first heating structure 300 and the drainage hole 410 are arranged in the groove 110. Further, the groove 110 forms a "匚" and / or a vertically flipped shape of "匚" around the air guide port, and the wind guide plate 100 is provided with at least two drainage holes 410, for example, the drainage holes 410 are two, three or four, etc. In this embodiment, the number of drainage holes 410 is two, and two drainage pipes 420 are also provided accordingly. The drainage hole 410 is provided at the corner of the groove 110, and the corner of the groove 110 is provided with a chamfer 111.
[0043] The "C" shape and its vertically flipped shape are the shapes formed by the extension of the groove 110. It can be understood that it surrounds the air guide opening and forms a notch. Compared with only setting the groove 110 on one side of the air guide opening, this solution enables the first heating structure 300 to be distributed at most positions around the air guide opening, fully preventing icing or frosting at different positions around the air guide opening; at the same time, it avoids excessive energy consumption caused by a full-wrap setting, thus achieving material and energy savings. Due to the shape design of the groove 110 in this solution, the melting speed can be accelerated, and the setting of at least two drain holes 410 can accelerate the drainage speed, thereby avoiding water accumulation.
[0044] When the water flows to the corner in the groove 110, due to the drainage effect of the chamfer 111, it will flow to the corner and stay for a while. Setting the drain hole 410 at the corner can further ensure that the water flow can smoothly flow into the drain hole 410 for drainage, improving the drainage efficiency and preventing the water flow from accumulating in the groove 110. The chamfer 111 here can be a rounded chamfer or an inclined chamfer, etc.
[0045] Further, the air guide opening is circular, and the distance between the two drain holes 410 is greater than the diameter of the air guide opening.
[0046] The air guide opening is circular, and the air guide ring 200 connected to it is also matched to be cylindrical, so there will be no corners, avoiding the accumulation of ice and frost at the corners. In addition, the design of the circular air guide opening and the air guide ring 200 also conforms to the principle of aerodynamics, ensuring that the air is transmitted more evenly and stably. The distance between two adjacent drain holes 410 is larger than the diameter of the air guide opening, ensuring that the two drain holes 410 are not too close to each other. The water flow does not need to flow to the same drain hole 410 to be discharged, but can flow to the drain hole 410 close to it, further improving the drainage efficiency.
[0047] Embodiment 2
[0048] Reference Figure 3 Referring to, this embodiment provides a top-outlet heat pump. The top of the top-outlet heat pump is provided with the deicing unit provided in Embodiment 1. The top-outlet heat pump further includes a chassis 500. The chassis 500 is provided with through holes 510 corresponding to the outlet of the drain pipe 420. In this embodiment, the chassis 500 is provided with two through holes 510 corresponding to the outlet position of the drain pipe 420, both of which are circular, and their sizes are preferably larger than the outlet size of the drain pipe 420, so that the water flowing out of the drain pipe 420 can pass through the through holes 510 and flow out of the heat pump.
[0049] In this embodiment, if there is accumulated water on the chassis 500, it can also be discharged through the through holes 510. The top-outlet heat pump equipped with the above deicing unit can prevent icing on the top and ensure the normal operation of the heat pump.
