Description

Technical Field

[0001] This invention relates to the field of refrigerator technology, and more particularly to a silent refrigerator that reduces resonance pulses. Background Technology

[0002] A refrigerator is a household appliance primarily used to refrigerate food and beverages to extend their shelf life. By lowering the temperature of food, it slows down the metabolism of food and the growth of microorganisms, thus prolonging its freshness. Refrigeration preserves the flavor, nutrients, and texture of food, making it fresher and more delicious. In addition, refrigeration prevents food from spoiling and reduces food waste. Refrigerators also have other uses, such as storing medicines and preserving seeds. The noise generated by a refrigerator during operation can disrupt sleep, especially for those sensitive to sound. Long-term exposure to refrigerator noise may lead to symptoms such as insomnia, tinnitus, fatigue, and memory decline. Refrigerator noise can also affect mood, causing irritability and affecting physical and mental health, and even work efficiency.

[0003] During the cooling and depressurization process of the refrigerant, the capillary tube used in refrigerators is prone to resonance and pulses due to large temperature and pressure changes. This not only leads to unstable refrigerant flow, resulting in poor evaporation in the evaporator and affecting the refrigerator's cooling effect, but also causes the internal temperature to rise, affecting food preservation. It can even lead to capillary tube breakage, increase the burden on the compressor, requiring the compressor to consume more energy to maintain the refrigeration cycle, increasing energy consumption, and potentially shortening the compressor's lifespan. Furthermore, the refrigerator compressor generates a certain amount of vibration during operation. If the vibration is too large, it may damage internal parts of the refrigerator, such as compressor failure and refrigerant leakage. In addition, excessive vibration can also affect the refrigerator's sealing performance, leading to cold air loss and affecting the cooling effect. Therefore, vibration damping design is necessary to protect the normal operation and lifespan of the refrigerator.

[0004] To address the aforementioned technical issues, Chinese Patent Application No. CN202020073087.6 discloses a movable shock-absorbing base for a refrigerator. This base utilizes silicone shock-absorbing strips on a placement plate to reduce pressure on the bottom of the refrigerator while simultaneously providing shock absorption. An insertion frame on the placement plate features a silicone air bladder ring on its top inner wall, which, when inflated, secures the refrigerator. Shock-absorbing feet further enhance the base's shock absorption effect, and double-brake universal wheels allow for refrigerator displacement and fixation. The design is convenient to operate and suitable for widespread use.

[0005] This movable shock-absorbing base for refrigerators can absorb shocks, but it cannot adjust the balance of the refrigerator body. It is inconvenient to deal with uneven ground environments. Due to the limitations of indoor conditions, the refrigerator body may be placed on uneven ground, which can easily affect the stability of the refrigerator body. In addition, it does not solve other noise sources inside the refrigerator, so the refrigerator is still very loud.

[0006] To address the aforementioned technical issues, Chinese Patent Application No. CN202110014355.6 discloses a compressor vibration damping mechanism and a refrigerator. The mechanism transmits irregular vibrations from the compressor in various directions to the damping pads. The angular momentum gained by the liquid within the damping chamber and the damping body is weaker than that of traditional rubber pads, thus reducing the ability to transmit vibrations to the base plate. The liquid filling the sealed damping chamber reduces compressor vibration. When the compressor's torsional vibration is transmitted to the damping body, the internal liquid also affects the damping mechanism's ability to further torsional vibration, resulting in better vibration damping for the compressor.

[0007] Although this compressor vibration damping mechanism and refrigerator can dampen the compressor, the installation process is relatively complicated, making it inconvenient to replace and maintain the compressor. Furthermore, the damping effect is limited and cannot dampen the refrigerator body itself, resulting in limited noise reduction and poor quiet operation.

[0008] To address this, a silent refrigerator that reduces resonant pulses is proposed. Summary of the Invention

[0009] The purpose of this invention is to provide a silent refrigerator with reduced resonance pulses, so as to solve the problems mentioned in the background art, such as the impact of capillary resonance and pulses on the refrigerator's cooling effect and the high resonance noise of the compressor.

[0010] To achieve the above objectives, the present invention provides the following technical solution: a silent refrigerator with reduced resonance pulses, comprising a compressor for compressing and pressurizing refrigerant and a capillary tube for throttling and depressurizing refrigerant inside the refrigerator body. The refrigerator body includes an anti-resonance pulse mechanism, which further includes an anti-vibration module and a limiting module. The anti-vibration module and the limiting module work together to reduce the resonance pulses generated by the operation of the capillary tube. The limiting module is used to control the position of the inlet and outlet ends of the capillary tube to improve the stability of the capillary tube.

[0011] Preferably, the anti-shake module includes a mounting plate disposed inside the refrigerator body. The upper end of the mounting plate is fixedly mounted with a limiting bladder by a support frame. The outer side of the limiting bladder is provided with a placement groove for limiting the position of the capillary tube, and the bottom end of the limiting bladder is provided with an air intake branch pipe.

[0012] Preferably, the limiting module includes heat shrink sleeves fitted on both ends of the limiting bladder. Each heat shrink sleeve has a stop block on its outer end. The inner ends of the two heat shrink sleeves are rotatably connected to a first connecting plate and a second connecting plate, respectively. The bottom end of the first connecting plate is rotatably connected to a sleeve. One end of a lead screw is threaded into the sleeve, and the other end of the lead screw is fixedly connected to the second connecting plate.

[0013] Preferably, at least two sets of sleeves and lead screws are provided, and the sleeves and lead screws are arranged in a circular and uniform manner.

[0014] Preferably, a noise reduction mechanism is provided on the outside of the compressor. The noise reduction mechanism also includes a positioning module and a buffer module. The positioning module includes a support airbag located at the bottom of the compressor. The support airbag is fixedly installed on the upper end of the mounting plate. A first airbag and a second airbag are provided on both sides of the compressor. The first airbag and the second airbag are both fixedly installed on the upright plate. The upright plate is fixedly installed on the upper end of the mounting plate.

[0015] Preferably, the buffer module includes a protective shell fitted on the outside of the compressor, a buffer pad fixedly installed at the top of the inner part of the protective shell, two sets of first airbags connected to the support airbags through an air supply pipe, a second airbag connected to the first airbags through an air supply pipe, an air intake main pipe provided at the bottom of the support airbags, and an air intake branch pipe connected to the air intake main pipe.

[0016] Preferably, the curvature of the upper end of the support airbag and the curvature of the lower end of the buffer pad are equal to the curvature of the upper and lower ends of the compressor, respectively, and the curvature of the inner sides of the first airbag and the second airbag are equal to the curvature of the outer side of the compressor.

[0017] Preferably, a repair mechanism is provided at the bottom of the refrigerator body. The repair mechanism also includes a multi-vibration damping module and an adjustment module. The multi-vibration damping module includes a fixing plate fixedly installed on the four right-angle bends at the bottom of the refrigerator body. A support spring and an annular airbag are fixedly connected to the bottom of the fixing plate. The other end of the support spring and the annular airbag are fixedly installed on the support foot.

[0018] Preferably, the support spring is sleeved inside the annular airbag, and the annular airbag is arranged in a circular shape.

[0019] Preferably, the adjustment module includes an air intake pump fixedly installed at the bottom of the refrigerator body. The air intake pump is connected to the main air intake pipe and four sets of annular airbags through a reversing valve. A pressure relief valve is provided on the side of the air intake pump.

[0020] The beneficial effects of this invention are:

[0021] 1. This invention designs an anti-shake module in conjunction with a limiting module. The limiting bladder restricts the capillary tube within the placement groove, reducing capillary resonance and pulse generation. This not only reduces noise generated by resonance but also ensures the refrigeration effect of the refrigerator. The limiting bladder can be inflated to increase the tightness of the capillary tube in the placement groove, enhancing the limiting effect. Furthermore, by threading the sleeve onto the lead screw, the distance between the two sets of heat shrink sleeves is brought closer, which can fix the inlet and outlet ends of the capillary tube onto the limiting bladder, preventing the capillary tube from detaching.

[0022] 2. This invention, through the design of a positioning module and a buffer module, can restrict the compressor from all sides, facilitating stable installation of the compressor. Furthermore, by inflating the support airbag, the first airbag, and the second airbag, and in conjunction with the buffer pad, not only can the compressor be installed stably, but the resonance of the compressor can also be buffered, reducing the noise generated by the compressor, thereby reducing the sound emitted by the refrigerator body.

[0023] 3. This invention, through the design of multiple shock-absorbing modules in conjunction with adjustment modules, allows the refrigerator body to be placed stably by means of the rebound force of the support spring and the annular airbag, while also mitigating the vibration of the refrigerator body and reducing noise generation. The air intake pump can supply air to four different annular airbags through the reversing valve, and the gas discharge can be controlled through the pressure relief valve, so that the refrigerator body can maintain stability even when placed on uneven ground. Moreover, it can supply and exhaust air to the main air intake pipe, and facilitate the disassembly and assembly of the compressor and capillary tube. Attached Figure Description

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0044] It should be noted that, unless otherwise defined, the technical or scientific terms used in this invention should have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains.

[0045] Please see Figures 1 to 17 This invention provides a technical solution: a silent refrigerator with reduced resonance pulses, comprising a refrigerator body 1 with a compressor 2 for compressing and pressurizing refrigerant and a capillary tube 5 for throttling and depressurizing refrigerant inside. The refrigerator body 1 includes an anti-resonance pulse mechanism, which further includes an anti-vibration module and a limiting module. The anti-vibration module and the limiting module work together to reduce the resonance pulses generated by the operation of the capillary tube 5. The limiting module is used to control the position of the inlet and outlet ends of the capillary tube 5, thereby improving the stability of the capillary tube 5. Figure 3As shown, the refrigerator body 1 is equipped with a cooling circulation mechanism, which includes a compressor 2, a condenser 3, a dryer filter 4, a capillary tube 5, and an evaporator 6. Specifically, after the refrigerator is started, the compressor 2 begins to operate, drawing in the refrigerant and compressing it into a high-temperature, high-pressure gas, which is then sent to the condenser 3. Through heat exchange with the surrounding air or water, the temperature of the refrigerant decreases, turning it into a high-temperature, high-pressure liquid refrigerant. This liquid refrigerant then passes through the dryer filter 4 to remove moisture and impurities, ensuring the purity of the refrigerant. The high-pressure liquid refrigerant then enters the evaporator 6 through the capillary tube 5. In the capillary tube 5, the temperature of the refrigerant rapidly decreases, turning it into a low-pressure, low-temperature liquid refrigerant. This liquid refrigerant then evaporates in the capillary tube 5, becoming a low-temperature, low-pressure gas, absorbing heat from the surrounding substances, thus lowering the temperature inside the refrigerator. The low-temperature, low-pressure gas then returns to the compressor 2 through the low-pressure suction pipe, re-entering the suction port of the compressor 2 to complete one refrigeration cycle.

[0046] like Figure 8 and Figure 9 as well as Figure 10As shown, during the cooling and depressurization process of the capillary tube 5, the large temperature and pressure changes can easily cause resonance and pulses. This not only leads to unstable refrigerant flow and poor evaporation in the evaporator 6, thus affecting the refrigerator's cooling effect, but may also cause the internal temperature of the refrigerator to rise, affecting the food preservation effect. It also increases the burden on the compressor 2, requiring the compressor 2 to consume more energy to maintain the refrigeration cycle, increasing the refrigerator's energy consumption and potentially shortening the compressor 2's lifespan. The anti-vibration module includes a mounting plate 7 installed inside the refrigerator body 1. The upper end of the mounting plate 7 is fixedly mounted with a limiting bladder 9 via a support frame 8. The outer side of the limiting bladder 9 is provided with a placement groove 10 to limit the position of the capillary tube 5. The bottom end of the limiting bladder 9 is provided with an air inlet branch pipe 11. The limiting module includes heat shrink sleeves 12 sleeved on both ends of the limiting bladder 9. The outer ends of the heat shrink sleeves 12 are each provided with a stop block 13. The inner ends of the two sets of heat shrink sleeves 12 are rotatably connected to a first connecting plate 14 and a second connecting plate 15, respectively. The bottom end of the first connecting plate 14 is rotatably connected to... There is a sleeve 16, with one end of a lead screw 17 internally threaded. The other end of the lead screw 17 is fixedly connected to the second connecting plate 15. At least two sets of sleeves 16 and lead screws 17 are provided, arranged in a circular and uniform manner. In use, the capillary tube 5 is first placed on the limiting bladder 9 along the mounting groove 10. Then, the limiting bladder 9 is inflated through the air inlet branch pipe 11, causing the limiting bladder 9 to expand and stably engage the capillary tube 5. Then, the sleeve 16 is rotated to thread the sleeve 16 onto the lead screw 17, thus connecting the two sets of heat-shrinkable sleeves 16. When the distance between the two ends is close, the two sets of heat shrink sleeves 12 are stably fitted onto the two ends of the limiting bladder 9 by the stop block 13. The heat shrink sleeves 12 are rotatably connected to the first connecting plate 14 and the second connecting plate 15, which will not obstruct the inlet and outlet of the capillary tube 5. This helps to limit the position of the capillary tube 5, reduce the resonance and pulse generation of the capillary tube 5, reduce the noise generated by resonance, ensure the cooling effect of the refrigerator, and fix the inlet and outlet of the capillary tube 5 on the limiting bladder 9 to prevent the capillary tube 5 from detaching.

[0047] As one embodiment of the present invention, such as Figure 12 and Figure 13 as well as Figure 14As shown, the compressor 2 of the refrigerator body 1 will generate a certain amount of vibration during operation. If the vibration is too large, it may cause damage to internal parts of the refrigerator, such as damage to the compressor 2 or refrigerant leakage. In addition, excessive vibration will also affect the sealing performance of the refrigerator body 1, leading to the loss of cold air and affecting the cooling effect. Therefore, in order to protect the normal operation and service life of the refrigerator body 1, a vibration reduction design is required. A noise reduction mechanism is set on the outside of the compressor 2. The noise reduction mechanism also includes a positioning module and a buffer module. The positioning module includes a support airbag 18 set at the bottom of the compressor 2. 8 is fixedly installed on the upper end of the mounting plate 7. A first airbag 21 and a second airbag 22 are provided on both sides of the compressor 2. Both the first airbag 21 and the second airbag 22 are fixedly installed on the vertical plate 20, which is fixedly installed on the upper end of the mounting plate 7. The buffer module includes a protective shell 23 fitted over the outside of the compressor 2. A buffer pad 24 is fixedly installed at the top of the inner part of the protective shell 23. The support airbag 18 is connected to two sets of first airbags 21 via an air supply pipe. The first airbags 21 are connected to the second airbags 22 via air supply pipes. An air intake main pipe 19 is provided at the bottom end of the support airbag 18, and a... The curvature of the upper end of the intake manifold 11, the support airbag 18, and the bottom end of the buffer pad 24 are equal to the curvature of the upper and lower ends of the compressor 2, respectively. The curvature of the inner sides of the first airbag 21 and the second airbag 22 are equal to the curvature of the outer side of the compressor 2. In use, the compressor 2 is first placed above the support airbag 18 and between the two symmetrical sets of the first airbag 21 and the second airbag 22. Then, the protective shell 23 is fixedly installed on the outside of the compressor 2, so that the buffer pad 24 inside the protective shell 23 is located at the upper end of the compressor 2. Then, the intake manifold 19 supplies air to the support airbag 18 and also supplies air to the compressor 2. The anti-resonance pulse mechanism connected to the air branch pipe 11 supplies air. Since the support airbag 18 is connected to the first airbag 21, and the first airbag 21 is connected to the second airbag 22, the support airbag 18, the first airbag 21, and the second airbag 22, together with the buffer pad 24, can fix the compressor 2, which helps to limit the compressor 2 and facilitates the stable installation of the compressor 2. Furthermore, through the cooperation of the support airbag 18, the first airbag 21, the second airbag 22, and the buffer pad 24, the resonance of the compressor 2 can be buffered, reducing the noise generated by the compressor 2, thereby reducing the sound emitted by the refrigerator body 1.

[0048] As one embodiment of the present invention, such as Figure 15 and Figure 16 as well as Figure 17As shown, the noise generated by the refrigerator body 1 during operation may interfere with people's sleep, especially for those who are sensitive to sound. Long-term exposure to refrigerator noise may lead to symptoms such as insomnia, tinnitus, fatigue, and memory decline. The noise from the refrigerator body 1 may also affect people's mood, making them feel irritable and restless, affecting their physical and mental health, and even affecting their work efficiency. Therefore, it is necessary to dampen the refrigerator body 1. A repair mechanism is set at the bottom of the refrigerator body 1. The repair mechanism also includes multiple damping modules and adjustment modules. The multiple damping modules include fixing plates 25 fixedly installed on the four right-angle bends at the bottom of the refrigerator body 1. The bottom end of the fixing plate 25 is fixedly connected to a support spring 26 and an annular airbag 27. The other end of the support spring 26 and the annular airbag 27 are fixedly installed on the support foot 28. The support spring 26 is sleeved inside the annular airbag 27, which is circular in shape. Specifically, the support spring 26 and the annular airbag 27 set between the fixing plate 25 and the support foot 28 at the bottom of the refrigerator body 1 can cooperate to support... This system provides stable placement and a dual buffering effect, mitigating vibration and reducing noise in the refrigerator body 1. Due to indoor conditions, the refrigerator body 1 may be placed on uneven ground, affecting its stability. If the refrigerator body 1 is unbalanced, components such as the compressor 2 and condenser 3 inside the refrigerator body 1 may be subjected to additional pressure, leading to damage or reduced cooling performance. An unbalanced refrigerator body 1 is also prone to vibration and noise, affecting the user experience. The adjustment module includes an intake pump 29 fixedly installed at the bottom of the refrigerator body 1. The intake pump 29 is connected to the intake main pipe 19 and four sets of annular air bags 27 via a reversing valve 30. A pressure relief valve 31 is provided on the side of the intake pump 29. During use, the intake pump 29 can supply air to the four different annular air bags 27 through the reversing valve 30, and the pressure relief valve 31 can control the gas discharge, ensuring that the refrigerator body 1 remains stable even when placed on uneven ground. It can also supply air to the intake main pipe 19, facilitating the disassembly and assembly of the compressor 2 and capillary tube 5.

[0049] Working principle: The refrigerator body 1 is equipped with a cooling circulation mechanism, which includes a compressor 2, a condenser 3, a dryer filter 4, a capillary tube 5, and an evaporator 6. Specifically, after the refrigerator is started, the compressor 2 starts to run, drawing in the refrigerant and compressing it into a high-temperature, high-pressure gas, which is then sent to the condenser 3. Through heat exchange with the surrounding air or water, the temperature of the refrigerant is lowered, turning it into a high-temperature, high-pressure liquid refrigerant. This liquid refrigerant then passes through the dryer filter 4 to remove moisture and impurities, ensuring the purity of the refrigerant. The high-pressure liquid refrigerant then enters the evaporator 6 through the capillary tube 5. In the capillary tube 5, the temperature of the refrigerant drops rapidly, turning it into a low-pressure, low-temperature liquid refrigerant. This liquid refrigerant then evaporates into a low-temperature, low-pressure gas, absorbing heat from the surrounding substances, thus lowering the temperature inside the refrigerator. The low-temperature, low-pressure gas returns to the compressor 2 through the low-pressure suction pipe and re-enters the suction port of the compressor 2, completing one refrigeration cycle and ensuring that the refrigerator functions normally.

[0050] During use, because the capillary tube 5 experiences large temperature and pressure changes during the cooling and depressurization of the refrigerant, resonance and pulses can easily occur. This not only leads to unstable refrigerant flow and reduced evaporation efficiency in the evaporator 6, thus affecting the refrigerator's cooling performance, but may also cause the internal temperature of the refrigerator to rise, affecting food preservation. Furthermore, it increases the burden on the compressor 2, requiring it to consume more energy to maintain the refrigeration cycle, increasing energy consumption and potentially shortening the compressor 2's lifespan. First, the capillary tube 5 is fitted onto the limiting bladder 9 along the mounting groove 10. Then, the limiting bladder 9 is inflated through the intake branch pipe 11. The expansion of the limiting bladder 9 stably engages the capillary tube 5. Then, the sleeve 16 is rotated and threaded onto the lead screw 17 to bring the distance between the two sets of heat shrink sleeves 12 closer. The stop block 13 restricts the movement of the two sets of heat shrink sleeves 12, which are stably fitted onto both ends of the limiting bladder 9. The heat shrink sleeves 12 are rotatably connected to the first connecting plate 14 and the second connecting plate 15, which does not obstruct the entry and exit of the capillary tube 5. This helps to restrict the position of the capillary tube 5, reduce the resonance and pulse generation of the capillary tube 5, reduce the noise generated by resonance, ensure the cooling effect of the refrigerator, and fix the entry and exit of the capillary tube 5 on the limiting bladder 9 to prevent the capillary tube 5 from detaching.

[0051] The compressor 2 of the refrigerator body 1 will generate a certain amount of vibration during operation. If the vibration is too large, it may cause damage to internal parts of the refrigerator, such as damage to the compressor 2 or refrigerant leakage. In addition, excessive vibration will also affect the sealing performance of the refrigerator body 1, leading to the loss of cold air and affecting the cooling effect. Therefore, in order to protect the normal operation and service life of the refrigerator body 1, a vibration damping design is required. When using it, first place the compressor 2 above the support airbag 18 and between the two symmetrical sets of first airbags 21 and second airbags 22. Then, fix the protective shell 23 on the outside of the compressor 2, so that the buffer pad 24 inside the protective shell 23 is located at the upper end of the compressor 2. Then, the intake main pipe 19 supplies air to the support airbag 18 and also supplies air to the anti-resonance pulse mechanism connected to the intake branch pipe 11. Because the support airbag 18 is connected to the first airbag 21 and the first airbag 21 is connected to the second airbag 22, the support airbag 18, the first airbag 21 and the second airbag 22, together with the buffer pad 24, can fix the compressor 2, which is beneficial to restrict the compressor 2 and facilitate the stable installation of the compressor 2. Furthermore, through the cooperation of the support airbag 18, the first airbag 21, the second airbag 22 and the buffer pad 24, the resonance of the compressor 2 can be buffered, reducing the noise generated by the compressor 2, thereby reducing the sound emitted by the refrigerator body 1.

[0052] The noise generated by the refrigerator body 1 during operation may disturb people's sleep, especially for those who are sensitive to sound. Long-term exposure to refrigerator noise may lead to symptoms such as insomnia, tinnitus, fatigue, and memory decline. The noise from the refrigerator body 1 may also affect people's mood, making them feel irritable and restless, affecting their physical and mental health, and even impacting work efficiency. Therefore, it is necessary to dampen the vibration of the refrigerator body 1. The support spring 26 and the annular airbag 27 installed between the fixed plate 25 and the support foot 28 at the bottom of the refrigerator body 1 can work together to provide stable placement and a double cushioning effect, reducing the vibration of the refrigerator body 1 and lowering the noise generation. Due to indoor conditions, the refrigerator body 1 may be placed on uneven ground, which may affect its stability. If the refrigerator body 1 is not placed in an unbalanced manner, the compressor 2 and condenser 3 inside the refrigerator body 1 may be subjected to additional pressure, which may cause damage or a decrease in cooling effect. An unbalanced refrigerator body 1 is also prone to vibration and noise, affecting the user experience. The air intake pump 29 can supply air to four different annular air bags 27 through the reversing valve 30, and the gas discharge can be controlled through the pressure relief valve 31, so that the refrigerator body 1 can still maintain stability even when placed on uneven ground. It can also supply air to the main air intake pipe 19, which facilitates the disassembly and assembly of the compressor 2 and capillary tube 5.
