Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a silent refrigerator. Background Art

[0002] A freezer is a refrigeration device that maintains a constant low temperature. It is a common appliance used to preserve food or other items at low temperatures in life and is widely used in life and industry. With the improvement of living standards, consumers are no longer satisfied with the refrigeration effect and power consumption of freezers, and have high requirements for the noise of freezers.

[0003] The noise of freezers mainly comes from the noise of compressor startup and shutdown and the noise of compressor high-frequency operation suction and exhaust. Among them, the noise of compressor startup and shutdown is loud because the internal movement of the compressor shakes a lot, and even the movement hits the shell; the noise of compressor high-frequency operation suction and exhaust is mainly pneumatic noise, which is caused by the suction and exhaust pressure difference. At present, the noise of compressor startup and shutdown is reduced by installing vibration damping springs on the compressor movement, but the effect is not obvious. In addition, the suction end of the compressor is directly connected to the end of the return pipe. When the gas is sucked into the compressor when it is turned on, the vibration and noise of the pipeline are also obvious. Utility Model Content

[0004] The utility model aims to provide a silent refrigerator to solve the problem of high noise when the refrigerator compressor is started and stopped.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A silent refrigerator comprises a cabinet body and a compressor. A mounting plate is arranged on the bottom of the cabinet body. Two groups of mounting grooves are arranged on the mounting plate. A mounting buckle bent vertically upward is arranged in each of the mounting grooves. A shock absorbing member is fixedly arranged between the two mounting buckles of each group of the mounting grooves. The compressor is fixedly mounted on the two shock absorbing members.

[0007] As a further solution of the utility model: the shock absorbing component includes a shock absorbing foot pad, a shock absorbing plate and a fixing plate, the two shock absorbing foot pads are respectively mounted on the corresponding mounting buckles, the shock absorbing plate and the fixing plate are both fixedly mounted on the top of the two shock absorbing foot pads, and the fixing plate is fixedly mounted on the top of the shock absorbing plate.

[0008] As a further solution of the utility model: the damping plate has a raised portion on one side away from the fixing plate, a plurality of fixing holes are evenly formed on the raised portion, and the compressor is fixedly mounted on the raised portion through the fixing holes.

[0009] As a further solution of the utility model: a plug-in through hole is provided at the center of the shock-absorbing foot pad, and the corresponding mounting buckle is fixedly plugged into the plug-in through hole.

[0010] As a further solution of the utility model: two positioning through holes are symmetrically provided on the fixing plate, and the two positioning through holes are respectively fixedly sleeved on the top ends of the two shock-absorbing foot pads.

[0012] As a further solution of the utility model: shock-absorbing cement is additionally provided at the junction of the capillary tube and the evaporator of the freezer.

[0013] The utility model has the following beneficial effects:

[0014] By providing a mounting plate with mounting grooves and mounting buckles and a shock-absorbing member, the shock-absorbing member can be conveniently and quickly fixed to the mounting plate through the mounting buckles. On the one hand, the shock-absorbing member plays a role in reducing vibration and noise when the compressor is started and stopped. On the other hand, the mounting groove cooperates with the shock-absorbing member to limit the start-up and shutdown process of the compressor, thereby reducing the start-up and shutdown shaking.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-6 As shown, the embodiment of the utility model provides a silent refrigerator, including a cabinet body 1 and a compressor 2. Figure 1 As shown, a compressor 2 compartment is provided at the bottom of the cabinet 1, and the inner cavity of the compressor 2 compartment also contains components such as the compressor 2, the fan, the suction and exhaust pipes, and the bottom cooling fan. The noise of the compressor 2 is mainly the noise of the compressor 2 starting and stopping. A mounting plate 3 is provided at the bottom of the cabinet 1, as shown in FIG. Figure 3 As shown, the mounting plate 3 is provided with two groups of mounting grooves 31, each of which is provided with a mounting buckle 32 bent vertically upward. Figure 2 As shown, a shock absorbing member 4 is fixedly arranged between two mounting buckles 32 of each group of mounting grooves 31, and the compressor 2 is fixedly mounted on the two shock absorbing members 4. The two shock absorbing members 4 play a role in shock absorption when the compressor 2 is started and stopped. On the other hand, the mounting grooves 31 cooperate with the shock absorbing members 4 to limit the start-up and stop processes of the compressor 2, thereby reducing the start-up and stop shaking.

[0027] like Figure 5 As shown, the shock absorbing component 4 includes a shock absorbing foot pad 41, a shock absorbing plate 42 and a fixing plate 43. The two shock absorbing foot pads 41 are respectively mounted on the corresponding mounting buckles 32. The shock absorbing plate 42 and the fixing plate 43 are both fixedly mounted on the top of the two shock absorbing foot pads 41. The fixing plate 43 is fixedly mounted on the top of the shock absorbing plate 42.

[0028] Furthermore, the damping plate 42 has a protrusion 421 on one side away from the fixing plate 43 , and a plurality of fixing holes 422 are evenly formed on the protrusion 421 , and the compressor 2 is fixedly mounted on the protrusion 421 through the fixing holes 422 .

[0029] The shock absorbing member 4 of this structural design transmits the vibration generated during the start-up and shutdown of the compressor 2 to the shock absorbing foot pad 41 through the shock absorbing plate 42, thereby reducing noise and making the refrigerator silent during the start-up and shutdown of the compressor 2.

[0030] Specifically, Figure 4 As shown, a plug-in hole 411 is provided at the center of the shock-absorbing foot pad 41 , and the corresponding mounting buckle 32 is fixedly inserted into the plug-in hole 411 . This mounting method facilitates the installation of the shock-absorbing foot pad 41 and the shock-absorbing plate 42 .

[0031] Similarly, two positioning through holes are symmetrically opened on the fixing plate 43, and the two positioning through holes are respectively fixedly sleeved on the top of the two shock-absorbing foot pads 41. After the various components are installed, they are fixed and welded together. The entire shock-absorbing component 4 has a stable structure and a good shock-absorbing effect.

[0032] It should be noted that if Figure 6 As shown, the return air pipe 5 of the freezer is an annular spiral structure, and a protective cover 6 is provided at the connection between the end of the return air pipe 5 and the suction end of the compressor 2. The return air pipe 5 of the freezer is designed as an annular spiral structure, which can effectively slow down the flow rate of the gaseous working medium when the compressor 2 is sucked, compared with directly connecting the suction end of the compressor 2, thereby effectively reducing the vibration and noise generated by the suction of the compressor 2. In addition, a shock-absorbing cement 7 is added at the junction of the capillary tube and the evaporator of the freezer, which further effectively reduces the noise when the airflow is ejected and the capillary vibration caused.

[0033] The utility model improves the mounting plate 3 of the compressor 2 and sets a shock-absorbing member 4, so as to reduce the noise during the operation of the compressor 2. The redesigned shock-absorbing member 4 of the compressor 2 can reduce the vibration during the operation of the compressor 2. The return air pipe 5 of the freezer is designed as an annular spiral structure, which can effectively slow down the flow rate of the gaseous working medium when the compressor 2 inhales, thereby effectively reducing the vibration and noise generated by the suction of the compressor 2. A shock-absorbing glue 7 is added at the junction of the capillary tube and the evaporator of the freezer, which can further effectively reduce the noise during the air flow injection and the capillary vibration caused. Through the improvements in the above aspects, the freezer of the utility model can basically be in silent operation during the start-up and shutdown of the compressor 2, so that the freezer can be suitable for any scene.
