[0045] The specific embodiments of the present application have been shown and described in the above drawings, and will be described in more detail hereinafter. These drawings and written description are not intended to restrict the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0046] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described clearly and completely below in combination with the drawings in the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0047] In the field of commercial central heating, in order to balance the protection needs of the heat pump unit during transportation and the convenience of the installation site, a wooden bottom support is usually designed and installed under the base plate of the heat pump unit. This design aims to provide necessary structural support and buffer to resist the impact and vibration that may be encountered during transportation, so as to ensure the integrity of the components of the heat pump unit.

[0048] However, this design brings certain challenges in the actual installation process. The installer needs to remove the wooden base support in the user's home first, and then securely fix the heat pump unit at the preset position through rigid connection. This disassembly and assembly process undoubtedly increases the installation cost and prolongs the installation time. At the same time, the heat pump unit is fixed at the preset position through rigid connection, which can provide strong structural support and stability, but during the startup and continuous operation of the heat pump unit, it may cause a series of vibration and noise problems.

[0049] These vibration energies can easily pass through the interaction between the heat pump unit and the building structure, causing unnecessary disturbance and influence on the user's living space. In order to effectively alleviate this problem, a damping block is added at the bottom of the heat pump unit to absorb and disperse vibration energy, thereby reducing the transmission efficiency of noise.

[0050] However, this scheme has exposed a series of limitations in practical application. First, the installation process of the damping block is relatively complicated and inconsistent, requiring professional installers to operate carefully, which undoubtedly increases the overall installation cost and time. Second, even if the damping block is installed, the damping block may still be at risk of shaking or even displacement due to vibration during the long-term operation of the heat pump unit, which not only affects the stable operation and service life of the heat pump unit, but also may cause additional damage to the surrounding equipment and building structure.

[0051] To this end, the damping structure of the heat pump unit provided by the embodiments of the present application sets up a support assembly, a connecting rod and a damping piece, one end of the connecting rod is connected with the support assembly, the other end is connected with the chassis of the heat pump unit, the damping piece is sleeved on the connecting rod, and at least part of the damping piece is located in the limiting groove on the support assembly. The position of the damping piece is limited by the limiting groove to prevent the displacement or rotation of the support piece. In use, the connecting rod and the chassis are connected, the damping structure is fixed on the heat pump unit, and the damping structure can support the heat pump unit and resist certain impact and vibration. It can directly replace the traditional wooden base support to effectively protect the heat pump unit during transportation. After arriving at the position where the heat pump unit is installed, the support assembly is directly installed on the support platform for placing the heat pump unit to realize the installation of the heat pump unit. Compared with the traditional way, the wooden base support does not need to be replaced by the damping block, the complicated operation is saved, the convenience of transportation and installation of the heat pump unit is improved, and at the same time, the limiting groove and the connecting rod can limit the damping piece to prevent displacement or rotation of the damping piece. The damping piece can play a good damping effect in the use of the heat pump unit after transportation and installation, which can not only reduce noise but also protect the heat pump unit.

[0052] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific examples. The following specific examples can exist independently or in combination. For the same or similar concepts or processes, some examples may not be described again. The embodiments of the present application will be described below with reference to the drawings.

[0053] In some embodiments, as shown in Figure 1 , Figure 2 and Figure 3 , the vibration reduction structure of the heat pump unit includes a support assembly 120, a connecting rod 130, and a damping member 110.

[0054] The support assembly 120 is used to connect with the support platform on which the heat pump unit is placed. The support assembly 120 is located below the heat pump unit and is used to support the heat pump unit. The support assembly 120 is provided with a limiting groove 1221. One end of the connecting rod 130 is connected with the support assembly 120, and the other end is connected with the bottom plate 200 of the heat pump unit. The damping member 110 is sleeved on the connecting rod 130 and at least partially located in the limiting groove 1221.

[0055] The connecting rod 130 is mainly used to connect the bottom plate 200 and the support assembly 120, and needs to be able to support the heat pump assembly, so the connecting rod 130 needs to have a certain strength. It can be made of common metal materials that can meet the strength requirements of use. The connecting rod 130 can be connected with the support assembly 120 and the bottom plate 200 by welding or bolt connection, etc. This embodiment does not limit it.

[0056] Exemplarily, the connecting rod 130 is a screw rod, one end of which is welded with the support assembly 120, and the other end is connected with the bottom plate 200 by bolts. In this way, the connecting rod 130 and the support assembly 120 can have high connection strength, avoiding loosening between the screw rod and the support assembly 120 due to vibration or large pressure during use, and the connecting rod 130 and the bottom plate 200 can be easily connected.

[0057] Specifically, the damping member 110 is usually made of a material such as rubber or polyurethane that can absorb and disperse vibration energy. After the connecting rod 130 is connected to the base 200 of the heat pump unit, the top of the damping member 110 is in contact with the base 200, and the bottom is in contact with the support assembly 120. During transportation or operation of the heat pump unit, the damping member 110 can significantly reduce the vibration noise level of the heat pump unit during operation, providing a more quiet and comfortable living environment for users. Moreover, the damping member 110 is provided with a through hole, and the connecting rod 130 is inserted into the through hole. The connecting rod 130 cooperates with the limiting groove 1221 to limit the position of the damping member 110 and the support assembly 120, preventing the damping member 110 from rotating or displacing relative to the support assembly 120, so that the damping member 110 can effectively reduce vibration.

[0058] Meanwhile, the connecting rod 130 is directly connected to the base 200 and the support assembly 120, and cooperates with the damping member 110 to effectively support and fix the heat pump unit, reduce the risk of shaking and displacement of the heat pump unit, and improve the safety and reliability of the heat pump unit during operation.

[0059] In addition, during transportation of the heat pump unit, a wooden base is not required, and the damping structure 100 can replace the wooden base to protect the heat pump unit, thereby avoiding the cumbersome operation of disassembling the wooden base and installing the damping block during installation, effectively improving the convenience of transportation and installation of the heat pump unit, and also effectively reducing the installation cost.

[0060] In some embodiments, the end surface of the damping member 110 in contact with the limiting groove 1221 is polygonal, and the shape of the limiting groove 1221 is adapted to the shape of the damping member 110.

[0061] For example, the damping member can be a rubber block, and the cross section of the damping member is rectangular. The limiting groove 1221 is also rectangular, and the size of the limiting groove 1221 is adapted to the size of the damping member 110. The part of the damping member 110 embedded in the limiting groove 1221 is just clamped in the limiting groove 1221, so that the displacement or rotation of the damping member can be prevented by the shape of the damping member 110 and the limiting groove 1221, effectively limiting the position of the damping member 110.

[0062] In some embodiments, referring to Figure 4 As shown, the support assembly 120 includes a first support member 122 and a second support member 121.

[0063] The second support 121 is located below the first support 122 and is connected to the first support 122 by welding or bolt connection or the like, thereby supporting the first support 122. Meanwhile, the second support 121 is also provided with a mounting hole 1212, which can be a threaded hole, mainly used for connecting the support platform on which the heat pump unit is placed by a bolt or the like when the heat pump unit is installed, thereby limiting the position of the heat pump unit, facilitating on-site installation of the user, and enhancing the overall stability of the heat pump unit after installation.

[0064] The limiting groove 1221 is arranged on the first support 122, and the connecting rod 130 is also connected to the first support 122. The support assembly 120 is divided into the first support 122 and the second support 121, and one or more first supports 122 can be connected to the same second support 121 according to the support requirement, thereby improving the damping and support effect.

[0065] Exemplarily, the second support 121 is provided with two first supports 122, and the two first supports 122 are arranged in sequence along the extension direction of the second support 121.

[0066] In some embodiments, the second support 121 includes a first mounting plate 1213 and two first side plates 1211 arranged on opposite sides of the first mounting plate 1213, the first support 122 is connected to the side of the first side plate 1211 away from the first mounting plate 1213, and the mounting hole 1212 is arranged on the first mounting plate 1213.

[0067] Specifically, the second support 121 is a U-shaped structure, the first mounting plate 1213 is used to contact the support platform, and the mounting hole 1212 can be fixedly connected to the support platform by a bolt or the like, thereby preventing the second support 121 from moving, and correspondingly, one or more mounting holes 1212 can be arranged on the first mounting plate 1213 according to the actual situation, which is appropriate to effectively limit the position of the first support 122, which is not limited in this embodiment.

[0068] The side plates on both sides of the first mounting plate 1213 are connected to the first support 122, which can improve the support strength, thereby enabling the damping structure 100 to effectively support the heat pump unit.

[0069] Further, at least one of the two first side plates 1211 is provided with an operation hole in a region corresponding to the mounting hole 1212, and after reaching the installation position, a bolt can be directly put into the operation hole to fix the first support 122 on the support platform, thereby facilitating operation.

[0070] In some embodiments, the second support 121 further comprises two end plates 1215 arranged obliquely, the first side plate 1211 has two obliquely arranged oblique end faces at both ends in the extension direction, and the included angle between the oblique end faces and the first mounting plate 1213 is obtuse, and the two end plates 1215 are connected with the two oblique end faces of the first side plate 1211 respectively.

[0071] After the two end plates 1215 are connected with the two first side plates 1211, the strength of the second support 121 can be effectively improved, thereby improving the use performance of the second support 121, and meanwhile, the oblique end faces and the end plates 1215 cooperate to form a structure similar to a ship type, so that the supporting effect of the second support 121 can be further improved.

[0072] In addition, in order to facilitate the smooth circulation of the heat pump unit after the damping structure 100 is added, the oblique end face can be arranged only at the lower end of the end face of the first side plate 1211, specifically, the end portion of the first side plate 1211 can be formed as a structure similar to a cone, the inclined surface of the lower end of the end portion of the first side plate 1211 is the oblique end face, and the width of the end plate 1215 is the same as the length of the oblique end face.

[0073] Further, the first side plate 1211 can be provided with the first flange 1214 on the side away from the first mounting plate 1213, and the first support 122 is connected with the first flange 1214.

[0074] Specifically, the first flange 1214 extends towards the side where the two first side plates 1211 are close to each other, and the strength of the second support 121 can be effectively improved through the first flange 1214, and meanwhile, after the first flange 1214 is added, the contact area between the first support 122 and the second support 121 can be increased, and the connection strength between the first support 122 and the second support 121 can be improved.

[0075] In some embodiments, the first support 122 comprises a second mounting plate 1223 and two second side plates 1222 arranged on opposite sides of the second mounting plate 1223, a limiting groove 1221 is formed between the second mounting plate 1223 and the second side plate 1222, so that the first support 122 forms a structure similar to a U type, the second side plate 1222 is provided with a second flange 1224 on the side away from the second mounting plate 1223, and the connecting rod 130 can be welded in the middle of the second mounting plate 1223.

[0076] A plurality of first flanges 1214 are arranged on the first side plate 1211 along the extension direction of the first side plate 1211, and a mounting groove 1216 is arranged between adjacent first flanges 1214, when the second mounting plate 1223 and the second side plate 1222 are located in the mounting groove 1216, the second flange 1224 is overlapped on the first flange 1214 and connected with the first flange 1214.

[0077] Specifically, the extension direction of the second side plate 1222 is perpendicular to the extension direction of the first side plate 1211, the extension direction of the first mounting plate 1213 and the second mounting plate 1223 is the same, that is, the second mounting plate 1223 is in the mounting groove 1216 and overlaps the position where the first side plate is not provided with the first flange 1214, and the second flange 1224 overlaps the first flange 1214 on both sides of the mounting groove 1216 and is welded to the first flange 1214, so as to improve the strength of the first support 122, the connection strength between the first support 122 and the second support 121, and the relative position between the first support 122 and the second support 121 is also limited by the shape of the mounting groove 1216 and the first support 122.

[0078] The embodiment of the application also provides a heat pump unit, which comprises a chassis 200 and the damping structure 100 of the heat pump unit in the above embodiment.

[0079] One or more damping structures 100 of the heat pump unit can be arranged on the chassis 200, and the heat pump unit is effectively supported by the damping structure 100, and after the damping structure 100 is fixed on the chassis 200 by bolts, the damping member 110 is just in the key area between the chassis 200 and the first support 122, and the damping member 110 can effectively block and attenuate the transmission of the vibration and noise of the whole heat pump unit, so as to create a quiet use environment for the user.

[0080] It can be understood that the heat pump unit also comprises common structures such as a compressor and a heat exchanger, which are well known to those skilled in the art, and the embodiment will not be described here.
