Description

Technical Field

[0001] The invention relates to the technical field of air conditioning, and in particular to a compressor foot pad assembly, a compressor assembly and an air conditioner. Background Art

[0002] At present, vibration-damping pads are installed on the outdoor compressor of the air conditioner during installation. The vibration-damping pads are used to consume the vibration energy of the compressor when the compressor is running, reduce the transmission of the compressor vibration to the chassis and other sheet metal parts of the air conditioner, play a role in vibration reduction and noise reduction, and reduce the noise during the operation of the air conditioner. Therefore, when setting the pads during the operation of the compressor, the softer the pads, the better.

[0003] However, during the long-distance transportation of the air conditioner, due to the uneven road surface, the excitation is mostly low-frequency around 20Hz, and the foot pads need to be harder to avoid the foot pads being soft and reducing the fixed frequency of the structure, causing the compressor structure to resonate and cause excessive displacement and damage. This makes the requirements for the compressor foot pad assembly very different in the two situations of air conditioner transportation and operation. Summary of the invention

[0004] The main purpose of the present invention is to provide a compressor foot pad assembly, a compressor assembly and an air conditioner to solve the problem in the prior art that the compressor foot pad assembly cannot take into account the different vibration reduction requirements during the operation and transportation of the compressor and has a poor vibration reduction effect.

[0005] To achieve the above object, the present invention provides a compressor foot pad assembly, comprising:

[0006] A foot pad body, one end of which cooperates with the compressor body, and the other end cooperates with a base for supporting the compressor body, and the foot pad body is provided with a retractable support cavity for accommodating a fluid;

[0007] a piezoelectric energy harvester mounted on the compressor body and / or the base; and

[0008] A heating element is disposed in the support cavity, electrically connected to the piezoelectric energy harvester, and capable of heating the fluid in the support cavity;

[0009] In which, the piezoelectric energy harvester can be detachably installed on the compressor body and / or the base, and has a first working position cooperating with the compressor body and / or the base, and a second working position removed from the compressor body and / or the base, the first working position corresponds to the transportation state of the compressor body, and the second working position corresponds to the working state of the compressor body.

[0010] Further, the support cavity is arranged in the foot pad body and extends along a supporting direction of the foot pad body to the compressor body.

[0011] Furthermore, the foot pad body is made of elastic material, and can increase the overall support hardness when the support cavity expands, and reduce the overall support hardness when the support cavity contracts.

[0012] Furthermore, the heating element comprises a heating ring arranged around the supporting cavity.

[0013] Furthermore, the compressor foot pad assembly also includes a heat insulating member between the foot pad body and the heating element.

[0014] Furthermore, the thermal insulation component is a flexible thermal insulation sleeve extending along the inner wall of the support cavity.

[0015] Furthermore, there are multiple piezoelectric energy harvesters.

[0016] Furthermore, the compressor foot pad assembly is provided with a slot on the compressor body, and the piezoelectric energy harvester is detachably mounted in the slot.

[0017] The present invention also provides a compressor assembly, comprising a compressor body and a compressor foot pad assembly, wherein the compressor foot pad assembly is the compressor foot pad assembly as described above.

[0018] The present invention also provides an air conditioner, comprising a compressor assembly, wherein the compressor assembly is the above compressor assembly.

During the operation of the compressor, the piezoelectric energy harvester can be directly removed to reduce the expansion degree of the support cavity and the hardness of the foot pad, so that the compressor foot pad assembly can meet the vibration reduction requirements during the operation and transportation of the compressor, thereby ensuring the vibration reduction effect.

[0029] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0031] like Figures 1 to 3 As shown, according to the present embodiment, the compressor foot pad assembly cooperates with the compressor body 10 to stably mount the compressor on the base 20, thereby ensuring reliable operation of the compressor during transportation and operation.

[0032] The compressor foot pad assembly in this embodiment specifically includes: a foot pad body 41, one end of which cooperates with the compressor body 10, and the other end cooperates with the base 20 for supporting the compressor body 10, and the foot pad body 41 is provided with a retractable support cavity 43 that can be used to accommodate fluid; a piezoelectric energy harvester 30, the piezoelectric energy harvester 30 in this embodiment is installed on the compressor body 10; and a heating element 45, which is arranged in the support cavity 43, is electrically connected to the piezoelectric energy harvester 30, and can heat the fluid in the support cavity 43; wherein the piezoelectric energy harvester 30 is detachably installed on the compressor body 10, and has a first working position that cooperates with the compressor body 10, and a second working position that is removed from the compressor body 10, the first working position corresponds to the transportation state of the compressor body 10, and the second working position corresponds to the working state of the compressor body 10. Furthermore, the compressor foot pad assembly in the present embodiment is provided with a retractable support cavity 43 on the foot pad body 41, and a piezoelectric energy harvester 30 is provided to capture the electric energy generated by the vibration of the compressor or the base 20 during transportation, so as to heat the fluid in the support cavity 43 in the foot pad body 41 through the heating element 45. The fluid heating causes the support cavity 43 to expand to a certain extent, thereby increasing the hardness of the foot pad 40. During the operation of the compressor, the piezoelectric energy harvester 30 can be directly removed to reduce the expansion degree of the support cavity 43 and the hardness of the foot pad 40, so that the compressor foot pad assembly can meet the vibration reduction requirements during the operation and transportation of the compressor, thereby ensuring the vibration reduction effect.

[0033] In a variant embodiment of the present embodiment, the piezoelectric energy harvester 30 can be detachably mounted on the base 20, and the electric energy generated by the base 20 can also be used during the transportation of the compressor. Alternatively, the piezoelectric energy harvester is provided on both the base 20 and the compressor body 10, and the effect of increasing the hardness of the foot pad 40 by heating the fluid in the support cavity 43 through the generation of electric energy can also be achieved.

[0034] It is preferred that the fixed frequency of the piezoelectric energy harvester 30 in this embodiment is close to or consistent with the frequency during the transportation of the compressor, so that the piezoelectric energy harvester 30 can achieve resonance. The resonance makes the energy harvester have greater stress inside, thereby generating greater electrical energy, further ensuring the support strength of the compressor foot pad 40. The number and placement of the energy harvesters can be flexibly selected, and the electrical energy is connected to the electric heating wire in the support cavity 43 as an electric heating element through the wire.

[0035] It should be noted that the piezoelectric energy harvester 30 in this embodiment adopts the conventional piezoelectric energy harvester 30 in the prior art. The piezoelectric energy harvester 30 can directly capture the vibration energy of the compressor, convert the vibration energy into electrical energy, and directly power the heating element 45. Its specific structure will not be elaborated here.

[0036] Preferably, the support cavity 43 in this embodiment is arranged in the foot pad body 41 and extends along the supporting direction of the foot pad body 41 to the compressor body 10, so that when the fluid in the support cavity 43 is heated, the supporting strength of the support cavity 43 to the support pad body in the supporting direction of the compressor body 10 can be further enhanced, thereby further ensuring the vibration reduction effect.

[0037] Specifically, the foot pad body 41 in this embodiment is made of elastic material, and can increase the overall support hardness when the support cavity 43 expands, and reduce the overall support hardness when the support cavity 43 contracts.

[0038] Preferably, the heating element 45 in this embodiment includes a heating ring arranged around the support cavity 43, and the heating ring in the support cavity 43 heats the fluid in the support cavity 43. The fluid in the heating cavity can be a gas that expands with heat and contracts with cold, or a liquid that expands with heat and contracts with cold.

[0039] Preferably, the compressor foot pad assembly in this embodiment also includes a heat insulating member 46 between the foot pad body 41 and the heating element 45. The heat insulating member 46 is a flexible heat insulating sleeve extending along the inner wall of the support cavity 43. Furthermore, during the operation of the heating element 45, the setting of the heat insulating member 46 can ensure the heating effect of the heating element 45 on the fluid, thereby improving the hardness of the foot pad body 41, ensuring the transportation reliability of the compressor during transportation, and preventing the compressor structure from being damaged due to excessive displacement.

[0040] In this embodiment, there are multiple piezoelectric energy harvesters 30 to ensure the energy supply effect.

[0041] Specifically, the compressor foot pad assembly in this embodiment is provided with a slot on the compressor body 10, and the piezoelectric energy harvester 30 is detachably mounted in the slot, thereby facilitating the subsequent manual disassembly and assembly of the piezoelectric energy harvester 30 after the compressor is transported.

[0042] The present embodiment also provides a compressor assembly, including a compressor body 10 and a compressor foot pad assembly. The compressor foot pad assembly is the compressor foot pad assembly as described above. Therefore, the advantages possessed by the compressor foot pad assembly in the present embodiment should also be possessed by the compressor assembly in the present embodiment, which will not be repeated here.

[0043] The present embodiment further provides an air conditioner, including a compressor assembly. The compressor assembly is the above compressor assembly, and thus the air conditioner in the present embodiment should also have the advantages of the compressor in the present embodiment.

[0044] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
