The vibration reduction effect of the vibration reduction foot pad directly influences the vibration noise level of household appliances such as refrigerators, air conditioners and the like. However, the vibration damping foot pad in the related art has a large lateral stiffness, so that most of vibration excitation of the base angle of the compressor is transmitted to the mounting bolt and transmitted to the base plate through the mounting bolt, and then the base plate of the household appliance resonates to generate fundamental frequency (minimum natural frequency) resonance noise. That is, the vibration-damping foot pad in the related art has a limited vibration-damping effect, which is not favorable for obtaining a household appliance with low vibration noise.

In an embodiment, the number of the connecting structures is multiple, and the connecting structures are arranged at intervals in the arrangement direction from the second end to the first end.
In one embodiment, the distance between the inner wall of the first vibration damping structure and the outer wall of the second vibration damping structure is 2mm-8mm; and/or
The cavity penetrates through the second end, and the end face, far away from the first end, of the second vibration damping structure is flush with the end face of the second end; and/or

The invention provides a household appliance.
In the embodiment of the present invention, as shown in fig. 1 and 2, the home appliance 10 includes a base plate 200, a compressor 300, and a vibration-damping foot pad 400. In some embodiments, the household appliance 10 is a refrigerator, and in this case, the bottom plate 200 may be a bottom plate of a cabinet of the refrigerator. In some embodiments, the household appliance 10 is a split type air conditioner, and in this case, the base plate 200 may be a base plate of a cabinet of an outdoor unit of an air conditioner. In some embodiments, the household appliance 10 is a window air conditioner, and in this case, the bottom plate 200 may be a bottom plate of a cabinet of the window air conditioner.
The vibration-damping foot pad 400 connects the base plate 200 and the compressor 300. When the compressor 300 is operated, vibration is generated, and the vibration generated from the compressor 300 can be effectively prevented from being transmitted to the base plate 200 by connecting the base plate 200 and the compressor 300 through the vibration reduction foot pad 400, so that the household appliance 10 having relatively small vibration noise can be obtained.
Specifically, in the present embodiment, the vibration damping foot pad 400 connects the base plate 200 with the bottom corner 310 of the compressor 300. More specifically, in the present embodiment, the compressor 300 has two bottom corners 310, and the two bottom corners 310 are located at opposite ends of the bottom of the compressor 300, and in this case, the two bottom corners 310 may be considered to be spaced apart in the first direction. Each bottom corner 310 is connected to the base plate 200 by at least one vibration-damping foot pad 400. Specifically, in the present embodiment, each bottom corner 310 is connected to the base plate 200 through a plurality of shock absorbing foot pads 400, and the plurality of shock absorbing foot pads 400 are arranged at intervals along a second direction, which is perpendicular to the first direction. More specifically, in the present embodiment, each bottom corner 310 is connected to the base plate 200 by two shock absorbing foot pads 400.
In the present embodiment, as shown in fig. 7 and 8, the vibration damping foot pad 400 is fixed to the base plate 200 of the home appliance 10 by the mounting bolt 500, and an end of the vibration damping foot pad 400, which is away from the base plate 200, is connected to the bottom corner 310 of the compressor 300. In this manner, it is very convenient to implement the vibration-damping foot pad 400 to connect the base plate 200 with the bottom corner 310 of the compressor 300.
In some embodiments, as shown in fig. 7, the mounting bolts 500 are welded to the base plate 200. The shock absorbing foot pad 400 is sleeved on the mounting bolt 500 through the mounting channel 422. The pad 600 is placed on the upper surface of the damping foot pad 400, and the nut 700 is screwed into the top of the mounting bolt 500 to press the pad 600, i.e., the damping foot pad 400 is fixed to the base plate 200 of the home appliance 10.
In some embodiments, as shown in fig. 8, the shaft portion 510 of the mounting bolt 500 passes through the mounting channel 422 and the through hole of the base plate 200 in sequence, and the nut 700 is positioned on the side of the base plate 200 away from the vibration-damping foot pad 400 and screwed into the shaft portion 510 of the mounting bolt 500, such that the head portion 520 of the mounting bolt 500 presses against the upper surface of the vibration-damping foot pad 400, i.e., the vibration-damping foot pad 400 is fixed to the base plate 200 of the household appliance 10.
Generally, the outer diameter of the mounting bolt 500 is smaller than the inner wall of the mounting channel 422, so that in an ideal state, the mounting bolt 500 is spaced from the inner wall of the mounting channel 422, thereby preventing the mounting bolt 500 from directly contacting the inner wall of the mounting channel 422, and further, the vibration generated by the compressor 300 can completely pass through the entire height of the vibration-damping foot pad 400, and then be transmitted to the bottom plate 200 after being optimally absorbed, thereby preventing a part of the vibration generated by the compressor 300 from not completely passing through the entire height of the vibration-damping foot pad 400, that is, from passing through the contact portion between the inner wall of the mounting channel 422 and the mounting bolt 500 to the mounting bolt 500, and then being immediately transmitted to the bottom plate 200, resulting in the resonance of the bottom plate 200 and generating fundamental frequency (minimum natural frequency) resonance noise. In practical applications, the horizontal component of the vibration force generated by the compressor 300 during operation may cause the vibration-damping foot pad 400 to displace slightly, such that the mounting bolt 500 directly contacts the inner wall of the mounting channel 422, and further, a part of the vibration generated by the compressor 300 is transmitted to the mounting bolt 500 through the contact between the inner wall of the mounting channel 422 and the mounting bolt 500, and then transmitted to the bottom plate 200 immediately, such that the bottom plate 200 resonates, and a fundamental frequency (minimum natural frequency) resonance noise is generated.
To solve the above problems, in the present embodiment, the shock-absorbing foot pad 400 includes a first shock-absorbing structure 410, a second shock-absorbing structure 420, and a connecting structure 430, as shown in fig. 1 to 6.
The first vibration dampening structure 410 has a first end 412, a second end 414, and a cavity 416. The first end 412 is connected to the compressor 300. And a second end 414 is attached to the base plate 200. A cavity 416 extends through first end 412. In the present embodiment, the first end 412 may be considered as one end surface of the first vibration damping structure 410, i.e., the first end surface, and the second end 414 may also be considered as one end surface of the first vibration damping structure 410, i.e., the second end surface.
The second vibration dampening structure 420 is inserted into the cavity 416 and is clearance fit with the cavity 416. The second vibration dampening structure 420 has a mounting channel 422. The mounting passage 422 is provided for the mounting bolt 500 connecting the damping foot pad 400 and the base plate 200 to pass through. In the present embodiment, in the arrangement direction of the first end 412 and the second end 414, that is, in the up-down direction of the shock absorbing foot pad 400, two ends of the mounting channel 422 respectively penetrate through two end surfaces of the second shock absorbing structure 420, that is, the mounting channel 422 has two open ends, and the two open ends are located on two end surfaces of the second shock absorbing structure 420 one-to-one. In other embodiments, the mounting channel 422 may extend only through an end surface of the second vibration dampening structure 420 that is distal from the second end 414, i.e., the mounting channel 422 may extend only through an upper end surface of the second vibration dampening structure 420.
In the related art, the body portion of the shock absorbing foot pad 400 (other than the mounting channel 422) is a solid structure, and the lateral stiffness (i.e., horizontal stiffness) of the shock absorbing foot pad 400 is greater. When the mounting bolt 500 is directly contacted with the inner wall of the mounting channel 422, most of the vibration generated from the compressor 300 is transmitted to the mounting bolt 500 through the contact between the inner wall of the mounting channel 422 and the mounting bolt 500 and is immediately transmitted to the base plate 200, causing the base plate 200 to resonate, generating a fundamental frequency (minimum natural frequency) resonance noise.
In the vibration reduction foot pad 400, the second vibration reduction structure 420 is in clearance fit with the first vibration reduction structure 410 and is connected with the first vibration reduction structure 410 through the connecting structure 430, so that the main body part (the second vibration reduction structure 420 and the first vibration reduction structure 410) of the vibration reduction foot pad 400 has a hollow part and is not a solid structure, the transverse stiffness (i.e., the horizontal stiffness, i.e., the horizontal direction determined by the X axis and the Y axis in the three-dimensional rectangular coordinate system) of the vibration reduction foot pad 400 is small, and then after the vibration generated by the operation of the compressor 300 is transmitted to the first vibration reduction structure 410, a small part of the vibration can be transmitted to the second vibration reduction structure 420 through the connecting structure 430. In this way, even after the mounting bolt 500 is directly contacted with the inner wall of the mounting channel 422, the vibration that can be transmitted to the mounting bolt 500 through the second vibration mitigation structure 420 is very small (very weak), so that the mounting bolt 500 can be prevented from resonating with the base plate 200. Therefore, the vibration damping foot pad 400 has a good vibration damping effect, and is beneficial to obtaining the household appliance 10 with low vibration noise.
In this embodiment, the first end 412 is connected to the compressor 300, which means that the bottom corner 310 of the compressor 300 presses on the first end 412. Generally, the compressor 300 has a heavy weight, and when the compressor 300 is not operated, the bottom corner 310 of the compressor 300 may stably press against the first end 412, and when the compressor 300 is operated, vibration generated by the operation of the compressor 300 may cause the compressor 300 to be separated from the vibration-damping foot pad 400.
In order to solve the above problem, in the present embodiment, one end of the second vibration mitigation structure 420 protrudes out of the first end 412. The end of the second vibration damping structure 420 protruding out of the first end 412 is sleeved with a limiting portion 424. The position-limiting portion 424 and the first end 412 define a position-limiting groove 400a. The limiting groove 400a serves to prevent the compressor 300 from being separated from the vibration-damping foot pad 400. Wherein, the bottom corner 310 of the compressor 300 is provided with a mounting hole 312, and the inner diameter of the mounting hole 312 is smaller than the outer diameter of the limiting part 424. During assembly, the limiting portion 424 penetrates through the mounting hole 312 in an extrusion deformation manner, so that the bottom corner 310 of the compressor 300 is sleeved on the second vibration damping structure 420 and is limited between the limiting portion 424 and the first end 412. The limiting groove 400a defined by the limiting part 424 and the first end 412 can effectively prevent the compressor 300 from being separated from the shock-absorbing foot pad 400.
It is to be understood that, in other embodiments, when the first end 412 is connected to the compressor 300, that is, the bottom corner 310 of the compressor 300 is pressed on the first end 412, and the first vibration damping structure 410 is connected to the bottom corner 310 of the compressor 300 through a connecting member, the limiting portion 424 may be omitted, and the second vibration damping structure 420 may not protrude out of the first end 412.
In the present embodiment, the inner diameter of the mounting hole 312 is larger than the outer diameter of the second vibration damping structure 420. Therefore, the probability that the inner wall of the mounting hole 312 of the base angle 310 directly contacts with the outer wall of the second vibration damping structure 420 can be reduced, the probability that the vibration generated by the compressor 300 is directly transmitted to the second vibration damping structure 420 through the base angle 310 can be reduced, the vibration transmitted to the mounting bolt 500 through the second vibration damping structure 420 can be further reduced, and the resonance between the mounting bolt 500 and the base plate 200 can be further avoided. It should be noted that, when the compressor 10 is operated, even if the inner diameter of the mounting hole 312 is larger than the outer diameter of the second vibration damping structure 420, the inner wall of the mounting hole 312 of the base angle 310 may directly contact with the outer wall of the second vibration damping structure 420, but the base angle 310 of the compressor 300 is mainly pressed against the first end 412, and even if the inner wall of the mounting hole 312 of the base angle 310 directly contacts with the outer wall of the second vibration damping structure 420, the vibration that can be transmitted to the mounting bolt 500 is very small.
In the present embodiment, in the arrangement direction of the first end 412 and the second end 414, the opening width of the limiting groove 400a is greater than or equal to the thickness of the bottom corner 310. Thus, when the base 310 is assembled to the shock absorbing foot pad 400, the base 310 is generally spaced from the limiting portion 424. Therefore, the probability of contact between the base angle 310 and the limiting part 424 can be reduced, the probability of transmission of vibration generated by the compressor 300 to the second vibration reduction structure 420 through the base angle 310 can be reduced, the vibration transmitted to the mounting bolt 500 through the second vibration reduction structure 420 can be further reduced, and resonance between the mounting bolt 500 and the base plate 200 can be further avoided. When the compressor 10 is in operation, the bottom corner 310 may contact the stopper 424 even if the bottom corner 310 is spaced from the stopper 424, but the bottom corner 310 of the compressor 300 is mainly pressed against the first end 412, and even if the bottom corner 310 contacts the stopper 424, the vibration that can be transmitted to the mounting bolt 500 is very small.
In the present embodiment, an end of the limiting portion 424 away from the first end 412 is provided with a rounded corner 424a. Thus, the limiting portion 424 can pass through the mounting hole 312 more conveniently.
In the present embodiment, the limiting portion 424 is annular. The outer diameter of the stop 424 is the same as the inner diameter of the cavity 416. The outer diameter of the limiting part 424 is smaller than the inner diameter of the cavity 416, the limiting effect of the limiting part 424 on the bottom corner 310 of the compressor 300 is limited, and the outer diameter of the limiting part 424 is larger than the inner diameter of the cavity 416, so that the difficulty of the limiting part 424 penetrating through the mounting hole 312 is increased, and the assembly is not facilitated. Specifically, in the present embodiment, the outer diameter of the stopper portion 424 is 16mm to 22mm. More specifically, in the present embodiment, the outer diameter of the stopper portion 424 is 19mm.
In the present embodiment, the distance between the inner wall of the first vibration damping structure 410 and the outer wall of the second vibration damping structure 420 is 2mm to 8mm. When the outer diameter of the second vibration damping structure 420 is fixed, the distance between the inner wall of the first vibration damping structure 410 and the outer wall of the second vibration damping structure 420 is too large, which may result in the too large outer diameter of the vibration damping foot pad 400, and is not favorable for the vibration damping foot pad 400 to be applied to the household appliance 10, and the distance between the inner wall of the first vibration damping structure 410 and the outer wall of the second vibration damping structure 420 is too small, which is not favorable for reducing the transverse rigidity of the vibration damping foot pad 400. In combination with the above factors, the distance between the inner wall of the first vibration damping structure 410 and the outer wall of the second vibration damping structure 420 is set to be 2mm to 8mm. Specifically, in the present embodiment, the distance between the inner wall of the first vibration damping structure 410 and the outer wall of the second vibration damping structure 420 is 5mm.
In the present embodiment, the first vibration damping structure 410 has an outer diameter of 25mm to 31mm, and the second vibration damping structure 420 has an outer diameter of 11mm to 17mm. Specifically, in the present embodiment, the outer diameter of the first vibration damping structure 410 is 28mm, and the outer diameter of the second vibration damping structure 420 is 14mm.
In the present embodiment, the height of the first vibration mitigation structure 410 is 13mm to 19mm. Specifically, in the present embodiment, the height of the first vibration mitigation structure 410 is 16mm.
In the present embodiment, the second vibration damping structure 420 has an inner diameter of 5.5mm to 11.5mm. Specifically, in the present embodiment, the inner diameter of the second vibration damping structure 420 is 8.5mm.
In the present embodiment, both the inner wall and the outer wall of the first vibration damping structure 410 are cylindrical structures. The inner and outer walls of the second vibration damping structure 420 are also cylindrical structures.
In other embodiments, the inner wall and the outer wall of the first vibration damping structure 410 may be of other structures, such as a polygonal structure, and similarly, the inner wall and the outer wall of the second vibration damping structure 420 may be of other structures, such as a polygonal structure. In this case, the inner diameter and the outer diameter of the first vibration damping structure 410 are equivalent inner diameter and equivalent outer diameter of the inner diameter and the outer diameter described above, and the inner diameter and the outer diameter of the second vibration damping structure 420 are also equivalent inner diameter and equivalent outer diameter of the inner diameter and the outer diameter described above.
In the present embodiment, the structure of the inner wall of the first vibration mitigation structure 410 is the same as the structure of the outer wall of the second vibration mitigation structure 420. It is understood that in other embodiments, the structure of the inner wall of the first damping structure 410 and the structure of the outer wall of the second damping structure 420 may be different.
In the present embodiment, the thickness of the connection structure 430, the thickness of the second vibration damping structure 420, and the thickness of the first vibration damping structure 410 are sequentially increased. In this manner, first shock absorbing structure 410 may have better support strength and connecting structure 430 may have better deformability, which may further reduce the lateral stiffness of shock absorbing foot pad 400. Specifically, in the present embodiment, the thickness of the first vibration mitigation structure 410 is 3.5mm to 5.5mm, the thickness of the second vibration mitigation structure 420 is 2.25mm to 3.25mm, and the thickness of the connection structure 430 is 1.2mm to 1.8mm. More specifically, in the present embodiment, the thickness of the first vibration damping structure 410 is 4.5mm, the thickness of the second vibration damping structure 420 is 2.75mm, and the thickness of the connection structure 430 is 1.5mm.
In this embodiment, a cavity 416 extends through the second end 414. An end surface of the second vibration dampening structure 420 remote from the first end 412 is flush with an end surface of the second end 414. Thus, when the vibration reduction foot pad 400 is fixed to the base plate 200 by the mounting bolt 500, both the second vibration reduction structure 420 and the first vibration reduction structure 410 may be abutted against the base plate 200, so that the vibration reduction foot pad 400 may be more firmly fixed to the base plate 200.
It is understood that in other embodiments, the cavity 416 may extend through the second end 414, wherein an end of the first vibration damping structure 410 remote from the first end 412 is a closed end, and a closing plate is disposed at the end, and a surface of the closing plate remote from the first end 412 is an end surface of the second end 414. The end surface of the second vibration dampening structure 420 remote from the first end 412 is connected to the surface of the closure plate proximate the first end 412. In this manner, the closing plate may be fixed to the base plate 200 by the mounting bolts 500, thereby achieving the fixing of the shock-absorbing foot pad 400 to the base plate 200.
In the present embodiment, the connecting structure 430 is disposed obliquely with respect to the arrangement direction of the first end 412 and the second end 414, that is, the connecting structure 430 is disposed obliquely with respect to the first vibration damping structure 410. In this manner, a part of the vibration generated by the operation of the compressor 300 may be decomposed into lateral vibration (horizontal vibration) and longitudinal vibration (vertical vibration) along the connection structure 430 during the transmission to the second vibration reduction structure 420 through the connection structure 430, and the longitudinal vibration (vertical vibration) may not act on the second vibration reduction structure 420. Therefore, the connection structure 430 is disposed obliquely with respect to the first vibration damping structure 410, so that the vibration can be further prevented from being transmitted to the second vibration damping structure 420, and the base plate 200 can be further prevented from resonating, thereby generating a fundamental frequency (minimum natural frequency) resonance noise. And by adjusting the inclination angle at which the connecting structure 430 is obliquely arranged with respect to the first shock absorbing structure 410, lateral vibration (horizontal vibration) and longitudinal vibration (vertical vibration) can be adjusted, thereby producing the shock absorbing foot pad 400 satisfying different application requirements.
In this embodiment, the connection structure 430 and the arrangement direction of the first end 412 and the second end 414 form an included angle α that is opened toward the first end 412, that is, the connection structure 430 and the inner wall of the first vibration damping structure 410 form an included angle α that is opened toward the first end 412. Wherein the included angle alpha is 30-60 degrees. In this manner, the lateral vibration (horizontal vibration) and the longitudinal vibration (vertical vibration) can be made substantially the same. Specifically, in the present embodiment, the angle α is 45 °.
In the present embodiment, in the arrangement direction from the first end 412 to the second end 414, i.e., in the up-down direction of the shock-absorbing foot pad 400, the lower end of the connecting structure 430 is connected to the inner wall of the first shock-absorbing structure 410, and the upper end of the connecting structure 430 is connected to the outer wall of the second shock-absorbing structure 420. In this manner, the longitudinal vibration (vertical vibration) is directed toward the first end 412, so that the longitudinal vibration (vertical vibration) is sufficiently absorbed by the vibration-damping foot pad 400 and then transmitted to the second end 414 (base plate 200). It is understood that in other embodiments, the upper end of the connecting structure 430 may be connected to the inner wall of the first vibration damping structure 410, and the lower end of the connecting structure 430 may be connected to the outer wall of the second vibration damping structure 420 in the arrangement direction from the first end 412 to the second end 414.
In this embodiment, the connecting structure 430 includes a plurality of reinforcing ribs 432, and the plurality of reinforcing ribs 432 are arranged at intervals and surround the second vibration damping structure 420 for one circle. Thus, the structure stability of the vibration reduction foot pad 400 is facilitated, and the transverse rigidity of the vibration reduction foot pad 400 is conveniently reduced. And by arranging different numbers of the reinforcing ribs 432, the transverse vibration (horizontal vibration) and the longitudinal vibration (vertical vibration) can be adjusted, so that the vibration reduction foot pad 400 meeting different application requirements can be produced.
It is understood that in other embodiments, the connecting structure 430 may also be a hollow circular truncated cone structure, wherein a large head end of the circular truncated cone structure is connected with one of the inner wall of the first vibration damping structure 410 and the outer wall of the second vibration damping structure 420, and a small head end of the circular truncated cone structure is connected with the other of the inner wall of the first vibration damping structure 410 and the outer wall of the second vibration damping structure 420. Thus, the damping foot pad 400 is more beneficial to stable structure. Specifically, in the present embodiment, one connecting structure 430 includes four reinforcing ribs 432.
In the present embodiment, the connecting structure 430 is plural. In the arrangement direction from the first end 412 to the second end 414, a plurality of connecting structures 430 are arranged at intervals. Thus, the vibration reduction foot pad 400 is beneficial to stable structure. And by providing different numbers of connecting structures 430, lateral (horizontal) and longitudinal (vertical) vibrations can be accommodated to produce a shock absorbing foot mat 400 that meets the needs of different applications. Specifically, in the present embodiment, there are two connection structures 430.
It can be understood that the above-described vibration-damping foot pad 400 has elastic deformation properties. Specifically, in the present embodiment, the damping pad 400 is made of rubber, that is, the first damping structure 410, the second damping structure 420, the connecting structure 430 and the limiting portion 424 are made of rubber.
It is understood that the above-described vibration reduction foot pad 400 is used in the household appliance 10 having the compressor 300, and it is understood that in other embodiments, the above-described vibration reduction foot pad 400 may also be used in other devices having the compressor 300, which are not the household appliance 10. It is understood that in other embodiments, the above-mentioned vibration-damping foot pad 400 may be used in a device without the compressor 300, and the device may or may not be the household appliance 10.
The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
