[0028] The realization, functional features and advantages of the purpose of the present utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings. Detailed implementation manners
[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present utility model.
[0030] In the present utility model, unless otherwise clearly defined and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0031] In addition, in the present utility model, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.
[0032] The present utility model provides a heat pump device with an ice melting function, referring to Figures 1 to 6, a heat pump device with an ice melting function includes a chassis 1, a fin heat exchanger 3, a protective member 4, and a heating assembly 5. Among them, the chassis 1 has an installation surface 11, and a peripheral edge 12 enclosing the installation surface 11 is formed at the edge of the chassis 1. The fin heat exchanger 3 is installed on the installation surface 11, and the protective member 4 is fixedly installed on the peripheral edge 12. The fin heat exchanger 3 has an outer side 32 facing the external space, that is, the outer side 32 faces the protective member 4.
[0033] The heating assembly 5 is arranged between the outer side 32 of the fin heat exchanger 3 and the peripheral edge 12, and the heating assembly 5 is also arranged along the edge direction of the outer side 32 of the fin heat exchanger 3. The heating assembly 5 is used to provide heat for the chassis 1, the fin heat exchanger 3, and the protective member 4.
[0034] Since frosting of the fin heat exchanger 3 is concentrated on the outer side 32, when ice or frost melts into water, most of the water drains on the outer side 32 of the fin heat exchanger 3, that is, the drainage volume is relatively large at the bottom of the outer side 32. Therefore, when the drainage is not smooth or timely, it is relatively easy for ice to form at the bottom of the outer side 32. Based on the above scheme, by arranging the heating assembly 5 on the outer side 32 of the fin heat exchanger 3, on the one hand, it can ensure heating of the chassis 1 to achieve ice melting at the bottom of the chassis 1 and the fin heat exchanger 3, and on the other hand, it can well radiate heat to the bottom of the outer side 32 of the fin heat exchanger 3 to achieve complete ice melting of the fin heat exchanger 3. In this way, even when the heat pump drains water not smoothly or in a timely manner resulting in ice formation, the heating assembly 5 can completely melt the stubborn ice formation points at the bottom of the chassis 1 and the outer side 32 of the fin heat exchanger 3, ensuring that the fin heat exchanger 3 has good heat exchange efficiency, thereby improving the use reliability of the heat pump and enhancing the user experience.
[0035] The heat pump device further includes a compressor 2 and a pipeline structure. The compressor 2 is installed on the installation surface, and the compressor 2 forms a circulation loop with the fin heat exchanger 3 through the pipeline structure. The fin heat exchanger 3 also has an inner side 31, and the inner side 31 faces the compressor 2.
[0036] Refer to Figures 1 to 6 , the heating assembly 5 includes a heating element 51 and a plurality of fixing elements 52. The heating element 51 is arranged in a long strip shape and is arranged along the edge direction of the outer side 32 of the fin heat exchanger 3. The heating element 51 is in close contact with the chassis 1 and the peripheral edge 12. The plurality of fixing elements 52 are all installed on the peripheral edge 12 or the installation surface 11, and the plurality of fixing elements 52 are spaced apart along the arrangement direction of the heating element 51. The plurality of fixing elements 52 are all used to fix the heating element 51.
[0037] Set in this way to be able to fully melt the ice on the chassis 1, effectively avoid the situation of secondary icing caused by insufficient melting, and improve the operation reliability of the heat pump. The heating element 51 heats the chassis 1 and the fin heat exchanger 3 by means of heat conduction, so that the chassis 1 and the fin heat exchanger 3 can melt the ice cubes or frost on themselves to achieve the purpose of defrosting and deicing, ensuring the normal operation of the heat pump. The heating element 51 can also perform thermal radiation on the bottom of the outer side 32 of the fin heat exchanger 3, so as to completely melt the stubborn icing points at the bottom of the outer side 32 of the fin heat exchanger 3, achieve complete deicing, improve the deicing effect on the fin heat exchanger 3, thereby improving the heat exchange efficiency of the fin heat exchanger 3 and the operation reliability of the heat pump.
[0038] Among them, in the embodiment of the present application, taking the installation of multiple fixing members 52 on the surrounding edge 12 as an example for illustration. Specifically, multiple fixing members 52 are fixedly installed on the inner wall of the surrounding edge 12, and multiple fixing members 52 can be installed by installation methods such as screws, bonding or welding. The fixing member 52 can well fix the heating element 51 on the chassis 1, so that the heating element 51 can stably provide heat for the chassis 1 during the heating process, ensuring the heat conduction efficiency between the heating element 51 and the chassis 1.
[0039] The fixing member 52 can be a fixing block, and the fixing block is provided with a bayonet for clamping the heating element 51. The fixing member 52 can also be a fixing clip, and the fixing clip can clamp and fix the heating element 51. The fixing member 52 can also be other structural members with the function of fixing the heating element 51, as long as it can stably fix the heating element 51, and no specific limitation is made here.
[0040] The distance between the heating element 51 and the fin heat exchanger 3 is 10 - 20 mm. For example, the distance between the heating element 51 and the fin heat exchanger 3 can be 10 mm; the distance between the heating element 51 and the fin heat exchanger 3 can be 15 mm; the distance between the heating element 51 and the fin heat exchanger 3 can be 20 mm. The fin heat exchanger 3 generates heat by itself. On the one hand, it can prevent the heating element 51 from contacting the fin heat exchanger 3, which helps to protect the heating element 51 and reduce the possibility of damage to the heating element 51. On the other hand, it ensures the stability of the heating of the heating element 51 and the reliability of the ice melting of the heat pump device.
[0041] The heating element 51 can be a heating tape. The cross-section of the heating tape is circular, rectangular or L-shaped. When the cross-section of the heating tape is circular, the diameter of the heating tape is 5-8 mm. For example, the diameter of the heating tape is 5 mm; the diameter of the heating tape is 6 mm; the diameter of the heating tape is 7 mm; the diameter of the heating tape is 8 mm. When the cross-section of the heating tape is L-shaped, the heating tape is in close contact with the mounting surface 11 and also in close contact with the inner wall of the surrounding edge 12. This can further increase the contact area between the heating tape and the mounting surface 11 and the surrounding edge 12, improve the heat conduction efficiency of the heating tape to the chassis 1, better provide heat for the chassis 1, enable better heat conduction efficiency between the chassis 1 and the fin heat exchanger 3, and thus more thoroughly melt the stubborn icing point at the bottom of the outer side 32 of the fin heat exchanger 3, improving the defrosting and deicing effect on the chassis 1 and the fin heat exchanger 3.
[0042] The heating element 51 can also be other structural components that can provide heat, as long as they can provide heat for the chassis 1, and will not be listed one by one here.
[0043] Continue to refer to Figures 1 to 6 , the length of the heating element 51 is not less than the length of the protective member 4 distributed along the circumferential direction of the surrounding edge 12, that is, the length of the heating element 51 can be equal to or greater than the length of the protective member 4 distributed along the circumferential direction of the surrounding edge 12. With such a setting, the heating and deicing range of the heating element 51 can cover the protective member 4. In this way, when snow falls on the protective member 4, the heating element 51 can also thoroughly remove the snow on the protective member 4, improving the deicing performance of the heat pump device.
[0044] The surrounding edge 12 has a first mounting section 121, a second mounting section 122 and a third mounting section 123. The second mounting section 122 is located between the first mounting section 121 and the second mounting section 122 and is bent. The protective member 4 includes a first mesh body 41, a second mesh body 42 and a third mesh body 43. The first mesh body 41 is connected to the first mounting section 121, the second mesh body 42 is bent and connected to the second mounting section 122, and the third mesh body 43 is connected to the third mounting section 123. This not only facilitates the installation of the protective member 4 to better protect the fin heat exchanger 3, but also helps to independently disassemble the protective member 4, facilitating the maintenance of the heat pump during subsequent periods.
[0045] The sum of the widths of the first protective net body 41, the second protective net body 42, and the third protective net body 43 distributed in the circumferential direction along the periphery 12 is less than the length of the heating element 51. Since the first protective net body 41, the second protective net body 42, and the third protective net body 43 are all mesh structures, during a heavy snowstorm, the falling snow will land between the protective member 4 and the fin heat exchanger 3. Over time, the snow will accumulate between the protective member 4 and the fin heat exchanger 3. The heating element 51 can well melt the snow accumulated between the protective member 4 and the fin heat exchanger 3, effectively preventing the falling snow from accumulating between the protective member 4 and the fin heat exchanger 3 and avoiding icing.
[0046] In addition, heat conduction occurs between the protective member 4 and the chassis 1, so that the snow falling on the protective member 4 can also be melted, thereby improving the reliability of the entire heat pump.
[0047] The first protective net body 41 has a first bent mounting portion 411, and the first bent mounting portion 411 is fixedly mounted on the outer side 32 of the first mounting section 121. The second protective net body 42 has a second bent mounting portion 421, and the second bent mounting portion 421 is fixedly mounted on the outer side 32 of the second mounting section 122. The third protective net body 43 has a third bent mounting portion 431, and the third bent mounting portion 431 is fixedly mounted on the outer side 32 of the third mounting section 123.
[0048] With such a setting, on the one hand, it is convenient to install the first protective net body 41, the second protective net body 42, and the third protective net body 43, and on the other hand, it ensures the gap between the first protective net body 41, the second protective net body 42, and the third protective net body 43 and the fin heat exchanger 3, ensuring that the fin heat exchanger 3 can better perform heat exchange and improving the operating reliability of the heat pump.
[0049] Continue to refer to Figures 1 to 6 , the outer side 32 of the fin heat exchanger 3 has a bent region 33 and a side end region 34, and the heating element 51 has a first heating section 511, a second strong heating section 512, and a third strong heating section 513. The first heating section 511 is arranged corresponding to the position between the bent region 33 and the side end region 34, the second strong heating section 512 is arranged corresponding to the bent region 33, and the third strong heating section 513 is arranged corresponding to the side end region 34. The first heating power 511 has a first heating power, and both the second strong heating section 512 and the third strong heating section 513 have an equal second heating power, and the second heating power is greater than the first heating power.
[0050] With such a setting, on the one hand, it provides basic heat for the chassis 1 and the fin heat exchanger 3 to enable defrosting and deicing of the fin heat exchanger 3 and the chassis 1, and on the other hand, for the stubborn icing points on the bent region 33 and the two side end regions 34, the stubborn icing points are strongly melted by means of strong heating, that is, the stubborn icing points at the bottom position of the outer side 32 of the fin heat exchanger 3 are strongly melted, thereby realizing the complete dissolution of the ice and frost at the bottom of the outer side 32 of the fin heat exchanger 3.
[0051] In addition, it is also possible to defrost the dead corners such as the corners of the chassis 1, so as to more thoroughly melt the ice on the chassis 1 and improve the defrosting and de-icing effect of the heat pump.
[0052] There are two side end regions 34 on the outer side of the fin heat exchanger 3. Correspondingly, the number of the third strong heating sections 513 is set to two. The two third strong heating sections 513 are arranged in one-to-one correspondence with the two side end regions 34, so that the ice and frost at the bottom of the outer side 32 of the fin heat exchanger 3 can be completely melted, and the de-icing effect of the heat pump device can be improved.
[0053] The second heating power is twice the first heating power. The range of the first heating power is 140 - 200 W. For example, if the first heating power is 140 W, then the second heating power is 280 W; if the first heating power is 200 W, then the second heating power is 400 W. With such a setting, it can adapt to different severe cold weather. Even in more severe and harsh weather, the heating element 51 can ensure the defrosting and de-icing effect on the chassis 1 and the fin heat exchanger 3, that is, it can improve the cleaning effect on the stubborn icing points on the chassis 1, the bending region 33 and the two side end regions 34.
[0054] The heating assembly 5 further includes a heat preservation member (not shown in the figure). The heat preservation member is wrapped around the outside of the heating element 51. The heat preservation member serves to ensure that the heating element 51 can evenly transfer heat to the chassis 1 and the protective member 4, thereby improving the de-icing effect of the heating element 51.
[0055] The heat preservation member can be tinfoil, and the tinfoil is wrapped around the outside of the heating tape; the heat preservation member can also be a heat preservation coating or other materials with heat preservation performance, which is not specifically limited here.
[0056] Continue to refer to Figures 1 to 6 , the mounting surface 11 has a plurality of supporting convex portions 13. The plurality of supporting convex portions 13 are spaced apart along the extending path of the bottom of the fin heat exchanger 3. The plurality of supporting convex portions 13 are all used to support the bottom of the fin heat exchanger 3, so that a gap is formed between the bottom of the fin heat exchanger 3 and the mounting surface 11.
[0057] If ice forms between the chassis 1 and the fin heat exchanger 3, it will not only increase the risk of damage to the fin heat exchanger 3, but also affect the performance of the whole heat pump. Therefore, when defrosting and de-icing the chassis 1 and the fin heat exchanger 3, making use of the gap between the fin heat exchanger 3 and the chassis 1 helps to drain water, effectively avoiding the problem of re-icing caused by the remaining water between the chassis 1 and the fin heat exchanger 3.
[0058] The installation surface 11 is penetrated by a plurality of drain ports 14. The plurality of drain ports 14 are all arranged corresponding to the fin heat exchanger 3 and are spaced apart along the extension path at the bottom of the fin heat exchanger 3. Through the drain ports 14, the water on the chassis 1 can be quickly drained out, effectively preventing water from accumulating on the chassis 1 and avoiding the icing risk caused by poor or untimely drainage, thereby improving the defrosting and deicing efficiency and effect.
[0059] Referring to Figure 1 and Figure 2 , the heat pump device with an ice melting function further includes a control panel (not marked in the figure) and a fixing frame 6. The control panel is installed on the top of the fin heat exchanger 3, and the fixing frame 6 is used to fix the top of the control panel, the fin heat exchanger 3 and the protective member 4. With such a setting, the top of the control panel, the fin heat exchanger 3 and the protective member 4 are well stabilized by the fixing frame 6, ensuring the stability of the whole heat pump structure and improving the reliability of the whole machine operation.
[0060] The above are only the optional embodiments of the present invention, and do not limit the patent scope of the present invention accordingly.
