Description

Refrigerator with a refrigerator body

Technical Field

The invention relates to the technical field of refrigeration, in particular to a refrigerator.

Background

Fresh keeping, energy saving and environmental protection are perpetual subjects of refrigerator development. The fresh-keeping agent is energy-saving and environment-friendly, namely, the fresh-keeping time of the food can be prolonged to the greatest extent under the condition of consuming the least energy. In order to comply with the development of fresh-keeping and energy-saving technologies, the refrigeration technology of refrigerators is also continuously developed. Initially, a traditional single compressor single cycle refrigeration system is prone to maldistribution of energy resulting in large fluctuations in compartment temperature. To solve the above problems, a single-compressor dual-cycle refrigeration system is marketed. However, in situations where the user frequently uses or stores a large amount of food at a time, or when the ambient temperature is high, the refrigerating and freezing chambers will be simultaneously powered, and the system power supply is contradictory. The temperature of the stored food can fluctuate greatly, which is extremely unfavorable for reducing the food to the proper storage temperature as soon as possible. The double-compressor double-independent circulation refrigerating system is adopted, so that the contradiction between energy supply and demand can be avoided, and the phenomenon of energy waste can be solved. Meanwhile, the stable operation of the refrigerating system is ensured, the switching loss of the system is reduced as much as possible, the food is protected to the maximum extent, and the storage time of the food is prolonged.

When the double-compressor refrigeration system is adopted, two compressors are required to be installed on one supporting plate, but the beat vibration of the supporting plate is extremely easy to be caused when the working frequencies of the two compressors are close, and the supporting plate generates larger vibration acceleration at the moment, so that excessive noise is generated.

Referring to fig. 2 to 7, the connection structure 400 includes a bushing 410, a first connection member 420 and a second connection member 430 slidably disposed within the bushing 410. The first and

second connection members

420 and 430 are slidably inserted in the bushing 410 in the same direction, so that the first and

second connection members

420 and 430 can slide relatively. Opposite ends of the first and

second connection members

420 and 430 are respectively connected to one support plate 130.

When the vibration of one compressor 300 drives the corresponding support plate 130 to vibrate, and the vibration of the compressor 300 is transferred to the connection structure 400, the first connection member 420 and the second connection member 430 relatively slide, so that the influence of the support plate 130 on the other support plate 130 is effectively reduced, the resonance of the two support plates 130 is reduced, and the noise is reduced.

In some embodiments, the connection structure 400 does not include a bushing 410, and one connector has a limiting slot formed in an opposite end thereof, and the other connector is threaded into the limiting slot.

The end surfaces of the opposite ends of the first and

second connection members

The second connecting section 424 is disposed horizontally and is disposed through the sliding slot 411. The first arc 421 is disposed at the free end of the second connecting section 424. The first connecting section 422 is provided with a fixing hole 425 vertically penetrating therethrough, and the fastener 450 passes through the fixing hole 425 to fix the first connecting member 420 to the support plate 130.

In this embodiment, the second connecting member 430 and the first connecting member 420 are symmetrically disposed, and the structure of the second connecting member 430 refers to the structure of the first connecting member 420, which is not described herein.

Referring to fig. 2 to 10, the connection structure 400 further includes a damping block 440 located in the chute 411, opposite ends of the first connecting member 420 and the second connecting member 430 respectively penetrate through the chute 411, the first connecting member 420 and the second connecting member 430 are opposite and spaced apart, and the damping block 440 abuts against the first connecting member 420 and the second connecting member 430.

Opposite ends of the first and

second connection members

420 and 430 are abutted against the damping blocks 440 in the sliding grooves 411 to fill the sliding grooves 411 of the bushing 410, thereby ensuring structural strength of the bushing 410, preventing the bushing 410 from being deformed when used for a long time, and ensuring connection and support of the support plate 130.

Opposite ends of the first connecting piece 420 and the second connecting piece 430 are respectively abutted against the damping block 440, and when the supporting plates 130 vibrate to drive the first connecting piece 420 or the second connecting piece 430 to vibrate in the sliding groove 411, the first connecting piece 420 or the second connecting piece 430 can be in a state of being separated from the damping block 440 in the vibration process, so that mutual interference of the two supporting plates 130 is effectively reduced.

The periphery of the damping block 440 abuts against the peripheral wall of the chute 411. The damping block 440 is prevented from colliding with the peripheral wall of the sliding slot 411, and more noise is prevented from being generated.

The end surfaces of the damping block 440 facing the first and

second connection members

420 and 430 are formed with a second arc surface 441, and the second arc surface 441 is adapted to the first arc surface 421. In this embodiment, the second arc surface 441 encapsulates the first arc surface 421, so that the second arc surface 441 and the first arc surface 421 can have guiding function when contacting, and buffer the impact when the first connecting member 420 and the second connecting member 430 abut against the damping block 440, so as to reduce noise.

The damping block 440 damps the relative movement of the first and

second links

420 and 430. The cushion 460 dampens vibrations of the first and

second links

420 and 430 in a circumferential direction of the cushion 460.

In this embodiment, the through hole 442 is a circular hole, and the periphery of the cushion pad 460 is circular matching with the through hole 442, so that the stress of the periphery of the cushion pad 460 and the through hole 442 is balanced, and the cushioning effect is uniform. In some embodiments, the through holes 442 are elliptical holes, polygonal holes, or other shaped holes.

The outer circumference of the cushion pad 460 is in clearance fit with the through hole 442, so that the cushion pad 460 is installed in the through hole 442, a certain clearance is formed between the cushion pad 460 and the side wall of the through hole 442, so that a allowance for the movement of the damping block 440 is reserved, and the damping block 440 can move to a certain position when being impacted by the first connecting piece 420 or the second connecting piece 430, so that part of impact is absorbed, and the effect of buffering is achieved.

In this embodiment, the damping mass 440 is made of a rigid material and the cushion 460 is made of a flexible material. In some embodiments, the damping mass 440 is also made of a flexible material.

In some embodiments, the cushion 460 and the through-hole 442 are interference fit or transition fit.

The cushion 460 has a vertically penetrating via 461 formed therein; the through holes 412 in the bushing 410 are adapted to the through holes 461, and the fasteners 470 pass through the through holes 461 and through holes 412 to secure the cushion 460.
