Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of refrigerator noise reduction, in particular to a posture-switchable bottom plate vibration reduction support device and a refrigeration equipment. BACKGROUND

[0002] The compressor is the main source of vibration of the refrigerator. The refrigeration compressor used in the refrigerator generally adopts a single-stage reciprocating piston structure, and there is inevitably unbalanced force leading to compressor shell vibration. The vibration of the compressor shell continues to be transmitted to the refrigerator through two channels. One channel is through the feet to the bottom plate of the refrigerator, and then to the cabinet, exciting vibration radiation noise. Among them, the compressor is assembled on the upper surface of the bottom plate of the refrigerator, the bottom plate of the refrigerator is used to support the compressor and the water pan and other components, and the bottom plate of the refrigerator is also used to support the entire refrigerator cabinet. The bottom plate of the refrigerator is a thin metal plate, the middle part of the bottom plate is suspended, the longitudinal stiffness of the bottom plate is low, and resonance radiation noise is easily generated under the excitation of compressor vibration. If the support stiffness of the bottom plate is insufficient or the vibration transmitted by the compressor to the bottom plate is too large, the resonance noise of the bottom plate will inevitably increase, and the vibration transmitted by the bottom plate to the cabinet will also increase, which will inevitably lead to an increase in the resonance radiation noise of the cabinet. The other channel is through the suction pipe and the exhaust pipe to excite the pipeline vibration and the connection piece vibration radiation noise. Among them, the vibration of the compressor shell is directly transmitted outward through the metal suction pipe and the exhaust pipe, and the vibration along the pipeline will excite the pipeline resonance radiation noise. In addition, the exhaust pipe is connected with the plastic water pan, which will cause the water pan to resonate and radiate noise. Some cabinets are arranged with condensers, cooling fans, plastic flow guide covers and other structures in the compressor chamber, which will produce resonance radiation noise under the excitation of exhaust pipe vibration. The vibration transmission of the above two channels is the main source of noise of the refrigerator, which seriously affects the noise perception of the refrigerator and the user's comfort.

[0034] In an embodiment of the present application, a posture-switchable bottom plate vibration reduction support device and a refrigeration equipment are provided, please refer to Figures 1 to 7 shown.

[0035] A posture-switchable bottom plate vibration reduction support device, comprising a bottom plate 1, a support seat 2, a compressor 3 and a foot seat.

[0036] The bottom plate 1 is provided with four through holes 11, and the upper end of the bottom plate 1 is provided with the support seat 2.

[0037] The compressor 3 is located above the bottom plate 1, and the lower end of the compressor 3 is provided with the foot seat, and the foot seat is provided with a first support part 41 and a second support part 42, and the number and position of the second support part 42 correspond to the through holes 11. Among them, the first support part 41 and the second support part 42 are integrally formed, one second support part 42 is arranged on the front and rear sides of the first support part 41 respectively, the second support part 42 is bent downward relative to the first support part 41, and the longitudinal height of the first support part 41 is higher than the longitudinal height of the second support part 42.

[0038] When the refrigeration equipment is in the first posture during factory transportation, the first support part 41 abuts against the support seat 2. When the first support part 41 abuts against the support seat 2, the lower end of the second support part 42 does not contact the ground.

[0039] When the refrigeration equipment is to be put into use, the first support part 41 does not abut against the support seat 2, and the foot seat does not abut against the bottom plate 1 and the support seat 2, the second support part 42 passes through the through hole 11, and the lower end of the second support part 42 contacts the ground.

[0040] The first support part 41 cooperates with the two support seats 2 to jointly and stably support the first support part 41 through the two support seats 2.

[0041] The second support part 42 is provided with a fitting opening 421 at the lower end. The support pad 43 is made of elastic material. The support pad 43 is provided with a necked part 431. The necked part 431 cooperates with the fitting opening 421 to connect the support pad 43 to the lower end of the second support part 42, so that the support pad 43 contacts the ground.

[0042] In addition, the support pad 43 is provided with a suction cup 44 at the lower end. The suction cup 44 is connected to the ground to keep the compressor 3 relatively stationary with respect to the ground, so that the two limiting columns 22 do not contact the inner wall of the limiting opening 412.

[0043] The support seat 2 includes a support table 21 and two limiting columns 22 arranged on the support table 21. The two limiting columns 22 are arranged along the left and right directions.

[0045] When the first support part 41 abuts against the support seat 2, the support column 413 cooperates with the limiting groove 23, and the right limiting column 22 is located in the limiting opening 412. The support column 413 cooperates with the limiting groove 23 to limit the movement of the support column 413 along the horizontal left and right directions, thereby limiting the movement of the compressor 3 along the horizontal left and right directions. The right limiting column 22 is located in the limiting opening 412 to limit the movement of the right limiting column 22 along the horizontal front and back directions, thereby limiting the movement of the compressor 3 along the horizontal front and back directions.

[0046] When the first support part 41 does not abut against the support seat 2, the two limiting columns 22 are located in the limiting opening 412. The limiting opening 412 limits the movement of the two limiting columns 22 along the horizontal front, back, left, and right directions. It should be noted that the two limiting columns 22 do not contact the inner wall of the limiting opening 412 when the refrigeration equipment is in use and remains in the second posture.

[0047] The support table 21 is provided with a slope 24 on the left side of the left limiting column 22 to facilitate the operation of posture switching. Specifically, when the first posture is switched to the second posture, the first support part 41 is lifted upward, the support column 413 is moved out of the limiting groove 23, and the support column 413 continues to slide downward along the slope 24, and finally the two limiting columns 22 are located in the limiting opening 412, and the two limiting columns 22 are adjusted not to contact the inner wall of the limiting opening 412.
