Description

Technical Field

[0001] This utility model relates to the field of heating, ventilation and air conditioning equipment technology, and specifically to a heat pump. Background Technology

[0002] Currently popular heat pump units on the market typically feature decorative panels to meet users' personalized aesthetic needs. To ensure assembly stability, these panels are usually secured with screws. However, to further reduce costs and better suit personalized customization, heat pump units using vacuum-formed parts as decorative panels are becoming increasingly common. Because vacuum-formed parts are prone to deformation, the traditional method of relying on numerous screws to fix the decorative panels easily causes them to warp and deform, affecting the appearance. While screwless adhesive bonding processes can be effective, the relatively soft nature of vacuum-formed parts makes it difficult to guarantee a smooth bonding surface. Utility Model Content

[0003] This utility model provides a heat pump to solve the problem that the decorative panel of the heat pump in the prior art cannot be reliably installed when using vacuum-formed parts.

[0004] To achieve the above objectives, the present invention adopts the following technical solutions:

[0005] A heat pump includes a panel, a heat pump housing, and a top cover plate. The top cover plate is detachably mounted on the top of the heat pump housing, and the panel is detachably mounted on the side of the heat pump housing. The panel is a thermoformed part.

[0006] Multiple fasteners and a first slot are provided on the lower side of the top cover plate near the panel, with the fasteners extending out from the side of the top cover plate;

[0007] A first pad is glued to the inner side of the top edge of the panel. The first pad extends along the top edge of the panel. A plurality of second pads are glued to the bottom of the first pad. The second pads extend out of the side of the first pad near the top cover plate, and the position of the second pads corresponds to the position of the first slot.

[0008] The panel and the top cover can be directly connected. When the panel and the top cover are directly connected, the top surface of the fastener abuts against the bottom surface of the first pad, and the second pad is fitted into the first slot, with the bottom surface of the first slot abutting against the top surface of the second pad.

[0009] The horizontal height of the top surface of the fastener is greater than the horizontal height of the bottom surface of the first slot;

[0010] The panel can be reliably and easily installed on the heat pump by the contact between the fastener and the first pad, as well as the contact between the first slot and the second pad.

[0011] In one embodiment, a first connecting piece is provided on the bottom edge of the panel, and a second connecting piece is provided on the bottom edge of the heat pump housing near the panel. Both the first and second connecting pieces are provided with multiple connecting holes, and the positions of the connecting holes on the first connecting piece correspond to the positions of the connecting holes on the second connecting piece.

[0012] When connecting the panel and the top cover, the first connecting piece and the second connecting piece are connected by inserting fasteners through the connecting holes on the first connecting piece and the second connecting piece;

[0013] This allows the panel to be secured more reliably.

[0014] In one embodiment, the heat pump further includes a top frame detachably mounted on top of the heat pump housing, and a top cover plate detachably mounted on top of the top frame;

[0015] This allows for more flexible installation and connection methods and sequences between the top cover, the heat pump housing, and the panel.

[0016] In a further improved embodiment, a skirt is formed on the side of the top frame near the panel, and the skirt is provided with a plurality of sockets and a plurality of second slots. When the top frame is installed and connected to the top cover plate, the fastener passes through the sockets.

[0017] The position of the second slot corresponds to the position of the second pad, which is used to limit the second pad and leave space for the first slot and the second pad to cooperate.

[0018] This makes the connection between the top cover and the top frame more reliable and ensures installation flexibility.

[0019] In a further improved embodiment, the top of the heat pump housing has two sides perpendicular to the side near the panel, and the top frame has two sides perpendicular to the side near the panel, and a second mounting groove is provided. A third connecting piece extends below the second mounting groove. Multiple connecting holes are provided on the first mounting groove and the third connecting piece, and the positions of the connecting holes on the first mounting groove and the third connecting piece correspond to each other.

[0020] When the top frame is installed on the top of the heat pump box, the third connecting piece is fitted into the first mounting groove and is fixed by inserting fasteners through the connecting holes on the first mounting groove and the third connecting piece.

[0021] The top cover plate has two downward-facing fasteners on its two sides perpendicular to the side closest to the panel. When the top cover plate is installed above the top frame, the fasteners engage with the second mounting groove.

[0022] As a result, the reliability of the connection between the top cover, the top frame, and the heat pump housing is further enhanced.

[0023] The beneficial effects of this utility model are as follows:

[0024] The heat pump provided by this utility model utilizes the cooperation of a first pad, a second pad, a first slot, and a fastener to install and position the panel. By optimizing the connection and installation method of the panel, the reliability of the panel installation as a vacuum-formed part is ensured, and it is also easy to disassemble and assemble, thus having high practicality.

[0032] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0033] like Figure 1-5 As shown, this utility model embodiment provides a heat pump, including a panel 1, a heat pump housing 2, and a top cover plate 3; both the heat pump housing 2 and the top cover plate 3 are sheet metal structures, the heat pump housing 2 forms an accommodating space for accommodating the unit, the top cover plate 3 is detachably installed on the top of the heat pump housing 2, and the panel 1 is detachably installed on the side of the heat pump housing 2.

[0034] For ease of DIY, the panel 1 in the prior art is often a vacuum-formed part. As a vacuum-formed part, the panel 1 is not suitable for installation by adhesive (the contact surface between the panel 1 and the heat pump box 2 is difficult to ensure flatness, and the adhesive is not strong enough). Moreover, the use of screws should be minimized (screws can easily cause the vacuum-formed panel 1 to warp and deform). Therefore, as the main improvement of this utility model, a plurality of fasteners 31 and a first slot 32 are provided on the lower side of the top cover plate 3 near the panel 1. The fasteners 31 extend out of the side of the top cover plate 3. A first pad 11 is glued to the inner side of the top edge of the panel 1. The first pad 11 extends along the top edge of the panel 1. A plurality of second pads 12 are glued below the first pad 11. The second pads 12 extend out of the side of the first pad 11 near the top cover plate 3, and the position of the second pads 12 corresponds to the position of the first slot 32. Therefore, panel 1 and top cover 3 can be directly connected. When panel 1 and top cover 3 are directly connected, the top surface of fastener 31 abuts against the bottom surface of the first pad 11, providing upward support for the first pad 11. The second pad 12 is fitted into the first slot 32, and the bottom surface of the first slot 32 abuts against the top surface of the second pad 12, providing downward pressure for the second pad 12, thereby realizing the connection between panel 1 and top cover 3. Obviously, to ensure the reliability of the connection between panel 1 and top cover 3, the horizontal height of the top surface of fastener 31 should be greater than the horizontal height of the bottom surface of the first slot 32.

[0035] Furthermore, to enhance the fixing reliability of panel 1, a first connecting piece 13 is provided on the bottom edge of panel 1 (in a more specific embodiment, the first connecting piece 13 is bonded to panel 1, or the first connecting piece is integrally formed with panel 1), and a second connecting piece 21 is provided on the bottom edge of the heat pump housing 2 near panel 1. Both the first connecting piece 13 and the second connecting piece 21 have multiple connecting holes, and the positions of the connecting holes on the first connecting piece 13 correspond to the positions of the connecting holes on the second connecting piece 21. When panel 1 and top cover plate 3 are connected, fasteners such as bolts and screws are inserted through the connection. The connecting holes on the first connecting piece 13 and the second connecting piece 21 connect the first connecting piece 13 and the second connecting piece 21, enabling a direct connection between the panel 1 and the heat pump housing 2. This means that both the top and bottom of the panel 1 are fixed, resulting in high reliability of the panel 1 installation. Obviously, the cooperation of the first pad 11, the second pad 12, the first slot 32, and the fastener 31 is sufficient to position the panel 1. Therefore, the fasteners connecting the first connecting piece 13 and the second connecting piece 21 only serve as auxiliary fixation. The force borne by the fasteners is small, making it less likely to cause the panel 1 to warp or deform.

[0036] In another embodiment of this utility model, in order to ensure the reliability of the connection between the top cover plate 3 and the heat pump housing 2 while facilitating disassembly and assembly, the heat pump also includes a top frame 4. The top frame 4 is installed between the heat pump housing 2 and the top cover plate 3, that is, the top frame 4 is detachably installed on the top of the heat pump housing 2, and the top cover plate 3 is detachably installed above the top frame 4. Since both the top frame 4 and the heat pump housing 2 are sheet metal structures, their own structural strength is sufficient, and the top frame 4 and the heat pump housing 2 can be detachably connected by bolts, slots, etc. Obviously, if the top cover plate 3 is directly connected to the heat pump housing 2 and the panel 1, the installation connection method and installation sequence of the top cover plate 3 and the heat pump housing 2 and the panel 1 will be limited. However, after introducing the top frame 4, the installation connection method and installation sequence of the top cover plate 3 and the heat pump housing 2 and the panel 1 are more flexible.

[0037] Specifically, a skirt 41 is formed on the side of the top frame 4 near the panel 1. The skirt 41 is provided with multiple insertion slots 411 and multiple second slots 412. When the top frame 4 is installed and connected to the top cover plate 3, the fastener 31 passes through the insertion slots 411, thereby reinforcing the connection between the top frame 4 and the top cover plate 3. The position of the second slot 412 corresponds to the position of the second pad 12, which is used to limit the second pad 12 and leave space for the first slot 32 to cooperate with the second pad 12. Therefore, when the top frame 4, the top cover plate 3 and the panel 1 are assembled with the heat pump box 2, the top frame 4 is fixedly installed first. On the top of the heat pump housing 2, if the top cover plate 3 is installed first, the top cover plate 3 can be connected to the socket 411 through the fastener 31 to achieve connection and fixation with the top frame 4, and the presence of the top frame 4 does not affect the connection between the top cover plate 3 and the panel 1; if the panel 1 is installed first after the top frame 4 is installed, the second slot 412 can limit the second pad 12 (relative to the spatial position of the pre-adjusted panel 1), which facilitates the subsequent installation and connection between the top cover plate 3 and the panel 1. That is, in this embodiment, the introduction of the top frame 4 ensures the flexibility of installation and makes the connection between the top cover plate 3 and the top frame 4 more reliable.

[0038] Furthermore, to enhance the reliability of the connection between the top cover plate 3, the top frame 4, and the heat pump housing 2, the top of the heat pump housing 2 is provided with two sides perpendicular to the side near the panel 1, and the top frame 4 is provided with two sides perpendicular to the side near the panel 1 (i.e., two sides perpendicular to the skirt 41), and a third connecting piece 421 extends below the second mounting groove 42. Multiple connecting holes are provided on the first mounting groove 22 and the third connecting piece 421, and the positions of the connecting holes on the first mounting groove 22 and the third connecting piece 421 correspond. When the top frame 4 is installed on the top of the heat pump housing 2, the third connecting piece 421 is fitted into the first mounting groove 22, and is further connected and fixed by inserting bolts, screws, and other fasteners through the connecting holes on the first mounting groove 22 and the third connecting piece 421. The top cover plate 3 is provided with two sides perpendicular to the side near the panel 1, and the two sides are provided with downward-facing fasteners 31. When the top cover plate 3 is installed above the top frame 4, the fasteners 31 are fitted into the second mounting groove 42.

[0039] The heat pump provided by this utility model utilizes the cooperation of a first pad, a second pad, a first slot, and a fastener to install and position the panel. By optimizing the connection and installation method of the panel, the reliability of the panel installation as a vacuum-formed part is ensured, and it is also easy to disassemble and assemble, thus having high practicality.

[0040] The embodiments described above merely illustrate the implementation of this utility model, and should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
