Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heat pump equipment, in particular to an anti-icing structure for the air guide ring of a top-outlet heat pump. Background Technique
[0002] A heat pump is an energy-efficient 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 it cannot spontaneously go 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 work in the reverse cycle and can obtain a larger heating capacity, effectively utilizing the difficult-to-apply low-grade heat energy to achieve the purpose of energy conservation.
[0003] At present, a considerable part of the heat pumps on the market are top-outlet heat pumps. The air outlet is located on the top cover of the heat pump and faces upward. When the machine is running, the fan blades rotate, and the cold air 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. For example, when it rains at an ambient temperature below 0°C, the water hits the top surface of the heat pump and flows down along the edge of the air outlet of the air guide ring on the top of the heat pump 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, when the ice at the edge of the air guide ring accumulates to a certain extent, the fan blades of the blower hit the ice at the edge of the air guide ring during rotation, seriously affecting the normal rotation of the fan blades of the blower and causing the fan blades to be damaged.

[0009] According to the anti-icing structure of the air guide ring of a top-air outlet heat pump of the present utility model, the lower end of the annular inclined surface extends outward to the outer edge of the top cover.

[0038] Embodiment 1
[0039] As Figures 1 to 5 shown, a structure for preventing ice formation on the air guide ring of an upward air outlet heat pump in this embodiment includes a top cover 1 for installing on the top of the heat pump. An air guide ring 2 is integrally formed on the top cover 1. The air guide ring 2 is used to correspond to the air outlet of the heat pump, so that the fan of the heat pump can output air flow outward through the air guide ring 2. In this embodiment, the number of air guide rings 2 is two. In addition, a convex ring 3 is provided at the edge of the air outlet 21 at the upper end of the air guide ring 2. The convex ring 3 stands on the top of the top cover 1, that is, it protrudes vertically upward by a certain height on the top surface of the top cover 1.
[0040] It can be understood that in this embodiment, a vertical convex ring 3 is added on the top of the top cover 1 of the heat pump, and the vertical convex ring 3 is arranged around the edge of the air outlet 21 of the air guide ring 2. Thus, when rain hits the top surface of the top cover 1 of the heat pump, the convex ring 3 can block the rain from flowing along the top surface of the top cover 1 into the air outlet of the air guide ring 2, making it difficult for the rain or ice attached to the top of the heat pump to flow or slide into the air inlet of the heat pump. Therefore, the amount of ice formation in the air guide ring of the heat pump in a low-temperature environment can be reduced as much as possible to protect the fan blades of the heat pump from being damaged.
[0041] In one embodiment, as Figure 6 shown, an annular inclined surface 31 is formed on the outer edge of the convex ring 3. The beneficial effect of additionally forming an annular inclined surface 31 on the outer edge of the convex ring 3 is that when raindrops fall on the top of the convex ring 3, under the guidance of the annular inclined surface 31 and the action of gravity, the raindrops falling on the top of the convex ring 3 can more easily flow along the annular inclined surface 31 and disperse outward from the convex ring 3, so that the raindrops falling on the top of the convex ring 3 can be kept away from the air outlet of the air guide ring 2 as much as possible, further avoiding the rain from easily flowing into the air outlet of the air guide ring 2. Alternatively, compared with Figure 6 and Figure 7 shown, the above-mentioned annular inclined surface 31 can also be replaced by a ring-shaped arc surface 34, which can also make the raindrops falling on the top of the convex ring 3 more easily flow along the ring-shaped arc surface 34 and disperse outward from the convex ring 3.
[0042] In one embodiment, as Figure 6 shown, the annular inclined surface 31 extends obliquely from the top of the convex ring 3 towards the outer periphery of the air outlet of the air guide ring 2 and abuts downward against the top surface of the top cover 1 of the top cover 1. Therefore, the raindrops falling on the top of the convex ring 3 can flow along the annular inclined surface 31 and disperse to the top surface of the top cover 1 of the top cover 1, making it easier for the raindrops falling on the top of the convex ring 3 to reach the top surface of the top cover 1 of the top cover 1.
[0043] In one embodiment, in combination with Figure 5 and Figure 8 shown, a circle of rounded corners 32 is formed on the inner edge of the convex ring 3. The outer edge of the rounded corner 32 is horizontally butted against the top of the convex ring 3, and the inner edge of the rounded corner 32 is downward butted against the inner wall of the convex ring 3. That is to say, the rounded corner 32 is butted between the top of the convex ring 3 and the inner wall of the convex ring 3, making the connection between the inner wall of the convex ring 3 and the top of the convex ring 3 smoother. Therefore, when the fan of the heat pump blows out air upward through the air guide ring 2, under the action of the upward air flow force, part of the rainwater falling from the top of the convex ring 3 onto the inner wall of the convex ring 3 can flow reversely along the surface of the rounded corner 32 back to the top of the convex ring 3 under the action of the upward air flow. Therefore, to a certain extent, it can also prevent the rainwater falling from the top of the convex ring 3 onto the inner wall of the convex ring 3 from continuing to flow downward to the inner wall of the air guide ring 2 and then entering the air inlet of the heat pump.
[0044] Optionally, compared with Figure 8 and Figure 9 as shown, the above-mentioned rounded chamfer 32 can also be replaced by a chamfer 33, that is, a circle of chamfers 33 are formed on the inner ring edge of the convex ring 3. The outer edge of the chamfer 33 is horizontally butted against the top of the convex ring 3, and the inner edge of the chamfer 33 is downward butted against the inner wall of the convex ring 3. Similarly, it can make the inner wall of the convex ring 3 and the top of the convex ring 3 butt against each other more smoothly, so that part of the rainwater falling from the top of the convex ring 3 to the inner wall of the convex ring 3 can flow reversely along the surface of the chamfer 33 back to the top of the convex ring 3 under the action of the upward air flow.
[0045] Furthermore, in combination with Figure 4 and Figure 5 as shown, the top surface of the top cover 1 forms an inclined drainage surface. The convex ring 3 is located at the top of the inclined drainage surface, and the bottom edge of the inclined drainage surface extends to the outer edge of the top cover 1. Alternatively, the bottom edge of the inclined drainage surface can also be close to the outer edge of the top cover 1. Specifically, in this embodiment, the inclined drainage surface is a crescent-shaped arc surface 11 that arches upward. The convex ring 3 is arranged at the arch position on the top of the crescent-shaped arc surface 11, and the bottom edges on the relative two sides of the crescent-shaped arc surface 11 extend to the outer edge of the top cover 1 (similarly, the bottom edges on the relative two sides of the crescent-shaped arc surface 11 can also be respectively close to the outer edge of the top cover 1). Due to the above structure, when the rainwater flows from the convex ring 3 to the crescent-shaped arc surface 11 on the top cover 1, it can continue to flow outward along the arc surface of the crescent-shaped arc surface, realizing continuous guiding of the rainwater to leave the air outlet of the air guiding ring 2 and avoiding the rainwater from easily accumulating on the top cover 1.
[0046] For the convenience of manufacturing, the air guiding ring 2 is integrally formed on the top cover 1, and the convex ring 3 is integrally formed with the top cover 1 and the air guiding ring 2 on the top of the top cover 1. In addition, the air guiding ring 2 extends vertically downward from the top of the top cover 1 so that the bottom of the air guiding ring 2 is close to the air outlet of the fan inside the heat pump.
[0047] Embodiment Two
[0048] This embodiment is similar to Embodiment One, and the main difference is that, as Figure 10 shown, on the convex ring 3, the upper end of the annular inclined surface 31 is close to the inner wall of the convex ring 3. This structure can make the rainwater dripping onto the top of the convex ring 3 flow more easily to the annular inclined surface 31, so that the rainwater can flow outward through the annular inclined surface 31 faster to enable the rainwater to quickly move away from the air outlet of the air guiding ring 2.
[0049] Similarly, as Figure 11 shown, the upper end of the annular inclined surface 31 directly extends to the inner wall of the convex ring 3, and the above technical effect can also be achieved.
[0050] The parts not mentioned in this embodiment are the same as those in Embodiment One and will not be elaborated here.
[0051] Example 3
[0052] This embodiment is similar to Embodiment 1, and the main difference is that, as Figure 12 shown, on the convex ring 3, the lower end of the annular inclined surface 31 extends outward to the outer edge of the top cover 1. Therefore, the rainwater dripping onto the top of the convex ring 3 can flow directly along the annular inclined surface 31 to the outer edge of the top cover 1 and leave the top cover 1, improving the drainage speed of the top cover 1 and allowing the rainwater to move away from the air outlet of the air guide ring 2 more quickly.
[0053] Example 4
[0054] This embodiment is similar to Embodiment 1, and the main difference is that, as Figure 13 shown, different from the structure shown in Figure 4 , the top surface of the top cover 1 is replaced with a V-shaped surface 12 that bulges upward (replacing the crescent-shaped arc surface 11 in Figure 4 ). The convex ring 3 is fixed at the raised position on the top of the V-shaped surface 12. The bottom edges on both opposite sides of the V-shaped surface 12 extend to the outer edge of the top cover 1 respectively (similarly, the bottom edges on both opposite sides of the V-shaped surface 12 can also abut against the outer edge of the top cover 1 respectively). Due to the above structure, when the rainwater flows from the convex ring 3 to the V-shaped surface 12 on the top cover 1, it can continue to flow outward along the inclined surface of the V-shaped surface 12, realizing continuous guiding of the rainwater away from the air outlet of the air guide ring 2 and preventing the rainwater from easily accumulating on the top cover 1.
[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
