Detailed Description of the Embodiment

[0033] The following details the embodiments of the present utility model. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0035] In the description of the present utility model, if the first and second are described only for the purpose of distinguishing technical features, it should not be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or the sequence relationship of the indicated technical features.

[0036] In the description of the present utility model, unless otherwise clearly defined, words such as setting, installation, connection, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0037] An embodiment of the present utility model provides a cabinet assembly, which is applied to a water heater. The specific structure and function of the cabinet assembly provided by the embodiment of the present utility model will be further described below with reference to the text and drawings.

[0038] Currently, the cabinets of some heat pumps or water heaters are directly welded to the mounting brackets. To ensure the stability of the support of the mounting brackets, the mounting brackets are generally made of sheet metal materials with a relatively large thickness, which increases the overall machine load. In addition, the mounting brackets made of sheet metal materials are limited in terms of vibration isolation. During the transportation and installation of the cabinet, vibrations will be transmitted to the cabinet through the mounting brackets, easily causing the components inside the cabinet to become loose.

[0039] In the related art, some water heater cabinets adopt a split design of the cabinet and the mounting bracket. Although this solution can relatively reduce the overall weight, it cannot solve the problem of resonance between the cabinet and the mounting bracket during the operation of the heat pump or water heater cabinet. In addition, some heat pump or water heater cabinets add vibration damping pads between the cabinet and the mounting bracket, but the fixing of the vibration damping pads is not stable, and the ideal vibration damping effect cannot be achieved.

[0040] To solve the above problems, an embodiment of the present utility model provides a cabinet assembly, which is applied to a water heater. The specific structure and function of the cabinet assembly provided by the embodiment of the present utility model will be further described below by taking a heat pump or a water heater as an example and in combination with the text and drawings.

[0041] It should be noted that when the box body assembly is applied to a heat pump or a water heater, the box body 200 of the heat pump or the water heater and the mounting bracket are of a split structure and can be transported separately. The box body 200 of the heat pump or the water heater is connected to the mounting bracket through the chassis 100 and the damping assembly 300, so that it can be fixed on the mounting bracket.

[0042] It can be understood that a connection hole 329 is provided at the bottom of the damping member 320 of the box body assembly, and the damping member 320 and the mounting bracket can be connected by screws.

[0043] Referring to Figure 1 and Figure 2 , according to the box body assembly of the first aspect embodiment of the present utility model, it includes: a chassis 100, a box body 200, and a plurality of damping assemblies 300. The box body 200 is arranged at the upper end of the chassis 100, and a plurality of damping assemblies 300 are arranged below the chassis 100. The plurality of damping assemblies 300 cooperate to support the chassis 100 and the box body 200, avoiding the situation where the mounting bracket is directly welded to the chassis 100, effectively reducing the overall weight; and, the damping assembly 300 can effectively absorb the vibration generated during the operation of the water heater, and can avoid the phenomenon of resonance between the box body 200, the chassis 100 and the mounting bracket, resulting in loosening of the components.

[0044] Referring to Figure 1 , in some embodiments, the number of the damping assemblies 300 can be 4, 6, etc., and the number of the damping assemblies 300 can meet the condition of stably supporting the box body 200 and the chassis 100; for example, in some embodiments, the chassis 100 is generally square, and the number of the damping assemblies 300 is 4. The 4 damping assemblies 300 are respectively arranged at the four corners of the chassis 100 assembly, so as to realize the support for the chassis 100 and the box body 200.

[0045] Referring to Figure 2 and Figure 3 , in some embodiments, the chassis 100 includes a support plate 110 and a water receiving plate 120. The water receiving plate 120 is arranged at the lower end of the support plate 110 and is connected to the support plate 110. The support plate 110 can better bear the downward pressure of the box body 200 installed on its upper end, and, bear the downward pulling force of the water receiving plate 120 located at its lower end, and can ensure the structural stability of the chassis 100.

[0046] Referring to Figure 2, It can be understood that the support plate 110 is provided with water passing holes communicating with the water receiving tray 120, and a drain port 121 is provided in the middle of the water receiving tray 120. The water receiving tray 120 can collect the water droplets generated during operation, and the collected water droplets can be discharged from the drain port 121 to prevent them from directly dripping onto the ground, thereby keeping the surrounding environment dry and clean. In addition, the water receiving tray 120 can also collect and discharge the rainwater that may accumulate around the box body 200 in rainy days or humid environments, preventing the accumulated water from causing damage to the box body 200 or affecting its normal operation.

[0047] Refer to Figure 3 And Figure 4 , In some embodiments, the vibration damping assembly 300 includes a connecting column 310 and a vibration damping member 320. The connecting column 310 is cylindrical and its upper end is fixed on the support plate 110. The support plate 110 and the water receiving tray 120 are provided with perforations communicating with each other at the same position. The lower end of the connecting column 310 passes through the perforations on the support plate 110 and the water receiving tray 120 and extends to the lower end of the water receiving tray 120. The upper end of the connecting column 310 is fixedly connected to the support plate 110. The upper end of the vibration damping member 320 is connected to the lower end of the connecting column 310, and the upper end surface of the vibration damping member 320 presses against the lower end of the water receiving tray 120, so as to be able to fix the water receiving tray 120 at the lower end of the support plate 110, making the water receiving tray 120 and the support plate 110 connected as a whole, ensuring the stability of the structure of the chassis 100; and, the vibration damping member 320 is connected to the lower end of the water receiving tray 120, and multiple vibration damping members 320 cooperate to support the chassis 100 and the box body 200, so that the chassis 100 and the mounting bracket can be of a split structure, thus can be transported or installed separately, avoiding the situation where the mounting bracket is directly welded to the chassis, effectively reducing the overall weight; and, the vibration damping member 320 can effectively absorb the vibration generated during the operation of the box body 200, and can avoid the resonance between the box body 200 and the mounting bracket, which may cause the loosening of the screws and the abnormal sound of the wall, reducing the noise during operation.

[0048] It can be understood that the upper end of the connecting column 310 can be fixed on the support plate 110 by welding or riveting. After the vibration damping member 320 is connected to the connecting column 310, it is equivalent to being directly fixed on the support plate 110, and the connection between the vibration damping member 320 and the support plate 110 is stable; in addition, as the main load-bearing component in the chassis 100, the support plate 110 is fixed on the support plate 110 through the connecting column 310, which can ensure the reliability of the connection between the vibration damping member 320 and the chassis 100; and, the pressure borne by the support plate 110 can be directly transmitted to the vibration damping member 320 through the connecting column 310, which can avoid the phenomenon that the water receiving tray 120 is deformed by pressure; in addition, the vibration of the support plate 110 can also be directly transmitted to the vibration damping member 320 through the connecting column 310, which can ensure that the vibration damping member 320 can weaken the vibration to a large extent.

[0049] In some embodiments, the support plate 110 is a metal plate, which generally has high strength and rigidity, and can withstand the weight of the housing 200 and various pressures from the external environment, such as wind force, vibration, etc., to ensure the stable operation of the heat pump or water heater. In addition, the metal plate also has good vibration resistance, and can better withstand the vibration generated during the operation of the heat pump or water heater.

[0050] Reference Figure 3 and Figure 4 In some embodiments, the connecting column 310 is made of metal material, and the upper end of the connecting column 310 is fixed to the support plate 110. The reliability of the connection between the connecting column 310 and the support plate 110 can be ensured. The lower end of the connecting column 310 is provided with an external thread, and the upper end of the vibration damping member 320 is provided with a screw hole 324. The lower end of the connecting column 310 is inserted into the screw hole 324 of the vibration damping member 320 and is threadedly connected with the screw hole 324, thereby achieving high-strength fixation between the connecting column 310 and the vibration damping member 320, which can not only ensure that the connecting column 310 is not easy to loosen or separate when subjected to external force during transportation and installation; it can also better transmit the vibration on the support plate to the vibration damping member 320, thereby improving the vibration reduction effect.

[0051] Reference Figure 3 and Figure 4 In some embodiments, the connecting column 310 is a metal part and a welding cap 311 is provided at the upper end. The welding cap 311 is roughly circular and welded to the upper end of the support plate 110. Along the radial direction of the connecting column 310, the width of the welding cap 311 is greater than the width of the connecting column, thereby increasing the welding area between the connecting column 310 and the support plate 110, which is beneficial to ensure the stability of welding; and after welding, the connection between the connecting column 310 and the support plate 110 is located at the upper end of the support plate 110. When the box body 200 is installed to the chassis 100, the connection between the connecting column 310 and the support plate 110 can be covered, which can avoid the connection between the connecting column 310 and the support plate 110 being exposed to the outside world, which causes the connection between the connecting column 310 and the support plate 110 to be corroded.

[0052] It is understandable that a protective layer can also be sprayed at the connection between the connecting column 310 and the support plate 110 through a powder spraying process, thereby increasing the corrosion resistance of the connection between the connecting column 310 and the support plate 110 and ensuring the stability of the connection between the connecting column 310 and the support plate 110.

[0053] It is understandable that the connection column 310 can also be fixed to the support plate 110 by riveting. The connection between the riveted connection column 310 and the support plate 110 has a high strength and can withstand a large external force.

[0054] It can be understood that the water receiving tray 120 is a plastic part. The water receiving tray 120 made of plastic has a relatively low self-weight, which is beneficial to reducing the overall weight of the chassis 100. Moreover, the plastic material has good toughness and corrosion resistance, enabling the chassis 100 to be used in different external environments for a long time and better meeting the usage requirements.

[0055] Referring to Figures 4 to 6 , in some embodiments, the vibration damping member 320 includes a connecting seat 321, a vibration damping block 322, and a support base 323 arranged from top to bottom. The support base 323 is connected to the connecting seat 321 through the vibration damping block 322. Among them, the connecting seat 321 and the support base 323 are made of a firm material, such as plastic, metal, etc., so as to ensure the stability of the structures of the connecting seat 321 and the support base 323. The vibration damping block 322 is made of a flexible material, such as rubber, silica gel, etc., enabling the vibration damping block 322 to better absorb vibrations. The connecting hole 329 at the bottom of the vibration damping member 320 is located on the vibration damping block 322, facilitating the connection between the vibration damping member 320 and the mounting bracket. The connecting seat 321, the vibration damping block 322, and the support base 323 are arranged in sequence from top to bottom. The upper end of the connecting seat 321 is a plane, and a screw hole 324 extending upward is provided in the middle of the plane. The lower end of the connecting column 310 is inserted into the screw hole 324 and threadedly connected to the screw hole 324, thereby being able to fix the vibration damping member 320 on the connecting column 310, and the connection between the vibration damping member 320 and the connecting column 310 is stable and reliable.

[0056] It can be understood that during installation, align the screw hole 324 at the upper end of the vibration damping member 320 with the lower end of the connecting column 310, and then rotate the vibration damping member 320 so that the connecting column 310 is screwed into the screw hole 324 to fix the vibration damping member 320 on the connecting column 310. The installation method is simple and reliable. A connecting hole 329 is provided at the lower end of the support base 323, and the support base 323 and the mounting bracket can be connected by screws.

[0057] It should be noted that during the installation process, due to different installation conditions in different environments, the mounting bracket cannot be adjusted horizontally. However, in the embodiments of the present invention, the distance that the connecting column 310 is screwed into the screw hole 324 can be controlled by rotating the vibration damping member 320, thereby controlling the distance between the bottom of the vibration damping member 320 and the water receiving tray 120. Multiple vibration damping members 320 can cooperate to adjust the levelness of the chassis 100 to a certain extent, ensuring that the box body 200 mounted on the chassis 100 is horizontal.

[0058] Referring to Figure 5 and Figure 6, in some embodiments, the connecting seat 321 is generally cylindrical with both the upper end and the lower end being flat surfaces. A threaded hole 324 is provided at the upper end of the connecting seat 321, and a first connecting boss 325 is provided at the lower end. The overall shape of the first connecting boss 325 is cylindrical, and its diameter is smaller than that of the connecting seat 321. A stepped surface is formed between the connecting seat 321 and the first connecting boss 325; the upper end of the damping block 322 is recessed downward to form a first connecting groove 326. The first connecting groove 326 is generally a circular stepped groove. The diameter of the lower end of the first connecting groove 326 matches the diameter of the first connecting boss 325, and the diameter of the upper end matches the diameter of the connecting seat 321. The first connecting boss 325 is snapped into the first connecting groove 326, and the outer wall of the first connecting boss 325 is in close contact with the inner wall of the first connecting groove 326, thereby being able to increase the connection stability between the connecting seat 321 and the damping block 322.

[0059] It should be noted that the shape of the first connecting boss 325 can also be a triangular prism, a prism, etc. The specific shape of the first connecting boss 325 can be set according to actual needs as long as the condition of stable connection between the connecting seat 321 and the damping block 322 is satisfied.

[0060] Refer to Figure 5 and Figure 6 , in some embodiments, the lower end of the damping block 322 is recessed upward to form a second connecting groove 328. The second connecting groove 328 is a stepped groove. The overall shape of the support base 323 is cylindrical. An upward-extending second connecting boss 327 is provided at the upper end of the support base 323. The overall shape of the second connecting boss 327 is also cylindrical, and its diameter is smaller than that of the support base 323; the diameter of the upper end of the second connecting groove 328 matches the diameter of the second connecting boss 327, and the diameter of the lower end matches the diameter of the support base 323. The second connecting boss 327 is snapped into the second connecting groove 328, and the outer wall of the second connecting boss 327 is in close contact with the inner wall of the second connecting groove 328, thereby being able to increase the connection stability between the support base 323 and the damping block 322.

[0061] It should be noted that the shape of the second connecting boss 327 can also be a triangular prism, a prism, etc. The specific shape of the second connecting boss 327 can be set according to actual needs as long as the condition of stable connection between the support base 323 and the damping block 322 is satisfied.

[0062] Refer to Figure 4 and Figure 5, in some embodiments, the connecting seat 321 and the supporting base 323 are metal parts, the damping block 322 is a rubber part, the connecting seat 321, the supporting base 323 and the damping block 322 are integrally injection molded, and the connecting seat 321, the supporting base 323 and the damping block 322 can form an integral structure, which can not only ensure the reliability of the connection between the connecting seat 321, the supporting base 323 and the damping block 322, but also reduce the production cost.

[0063] It can be understood that the connecting seat 321 of the damping member 320 is a metal part, and the screw hole 324 at its upper end is in close fit with the connecting column 310, which can realize the high-strength fixation between the damping member 320 and the connecting column 310, and can ensure that the damping member 320 is not easily loosened or separated when subjected to external forces during transportation or installation; in addition, the vibration of the chassis 100 can also be transmitted to the damping block 322 through the connecting column 310 and the connecting seat 321, so that the damping block 322 can better absorb the vibration generated during the operation of the box body 200. The damping block 322 of the damping member 320 is a rubber part, and the elastic deformation of the rubber part can absorb and disperse the vibration energy transmitted from the connecting column 310, effectively reducing the transmission of vibration and achieving better damping and noise reduction effects. In addition, since the working environment of the box body 200 is relatively harsh, and the rubber part can meet the use requirements due to its wear resistance, corrosion resistance and aging resistance; the supporting base 323 of the damping member 320 is a metal part, and the supporting base 323 is a component connecting the damping member 320 and the mounting bracket. Being a metal part can realize the high-strength fixation between the damping member 320 and the mounting bracket, and can minimize the influence of the vibration of the box body 200 during operation on the connection stability between the damping member 320 and the mounting bracket.

[0064] Refer to Figure 3 and Figure 4 , in some embodiments, the lower end of the water receiving tray 120 is recessed upward at multiple places, so that a plurality of receiving grooves 122 are formed at the lower end of the water receiving tray 120. The number of the receiving grooves 122 corresponds to the number of the damping members 320 one by one. The lower end of the connecting column 310 extends into the receiving groove 122 and is flush with the lower end of the water receiving tray 120, which can avoid the phenomenon that the installation cannot be leveled due to the lower end of the connecting column 310 protruding from the lower end of the water receiving tray 120.

[0065] It can be understood that at the position where the lower end of the water receiving tray 120 is recessed upward, an abutting boss 123 is formed on the upper end of the water receiving tray 120. After the upper end of the connecting column 310 is fixed on the upper end surface of the supporting tray 110, the lower end is connected downward to the abutting boss 123, and the connecting column 310 is threadedly connected to the abutting boss 123, so that the water receiving tray 120 can be fixed to the lower end of the supporting tray 110.

[0066] It can be understood that the support plate 110 and the water receiving plate 120 can also be fixed by a plurality of screws, which will not be elaborated here.

[0067] Referring to Figure 4 , in some embodiments, the damping member 320 is connected to the connecting column 310, and the upper end of the damping member 320 is received in the receiving groove 122, which can reduce the overall height of the box assembly, thereby reducing the center of gravity of the box assembly and being beneficial to improving stability.

[0068] Referring to Figure 3 and Figure 4 , in some embodiments, the chassis 100 further includes a heat insulation layer 130, and the heat insulation layer 130 is provided between the support plate 110 and the water receiving plate 120. The heat insulation layer 130 can effectively isolate the external environment and the internal temperature difference and reduce the heat dissipation.

[0069] It can be understood that the heat insulation layer 130 can be made of materials such as heat insulation foam and heat insulation cotton, and the material of the heat insulation layer 130 is not limited herein.

[0070] The water heater according to the second aspect embodiment of the present invention includes: the box assembly as in the first aspect embodiment of the present invention.

[0071] According to the water heater of the embodiment of the present invention, the damping member 320 at the lower end of the chassis 100 can effectively absorb the vibration generated during transportation and installation, and can avoid the phenomenon that the internal components of the box 200 become loose due to the vibration transmitted to the box 200.

[0072] In some embodiments, the box 200 of the water heater further includes components such as a water pump, a compressor, a plate heat exchanger, an evaporator, and a water pipeline. The cooperation of the various components of the box assembly can realize the heating function of the water heater.

[0073] It should be noted that the box assembly can also be applied to electrical appliances such as heat pumps.

[0074] Of course, the present invention is not limited to the above embodiments. Those skilled in the art can make equivalent deformations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included in the scope defined by the claims of this application.
