Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of refrigerators, in particular to a refrigerator. Background Art
[0002] Refrigerators are widely used because they can maintain a low temperature in any season, making it easier to store food. During use, hot and humid air often enters the refrigerator, causing frost to form inside. Therefore, most refrigerators have a defrost function. Typically, an evaporating dish is installed inside the refrigerator to collect the defrost water, which is then evaporated, eliminating the need to drain the water outside.
[0003] The prior art provides a refrigerator evaporating dish assembly, comprising an evaporating dish and an evaporating tube disposed within the dish. The evaporating tube is a serpentine tube to increase its length and improve evaporation efficiency. The evaporating dish collects defrost water from the refrigerator. The evaporating tube is connected to a compressor, which provides the required temperature for evaporation, thereby evaporating the defrost water in the evaporating dish.
[0004] However, the prior art has the following problems: the pressure pulsation during operation of the compressor causes the evaporation tube to vibrate, which in turn causes the evaporation tube to collide with the wall of the evaporation dish, generating a large amount of noise. Utility Model Content
[0005] Some embodiments of the present application provide a refrigerator in which a vibration damping block is installed on an evaporating tube at a position where the evaporating tube is likely to touch the wall of an evaporating dish. The vibration damping block is used to prevent the evaporating tube from contacting the wall of the evaporating dish, thereby reducing resonance noise.
[0006] In order to achieve the above-mentioned purpose of the utility model, some embodiments of the utility model adopt the following technical solutions:
[0007] Some embodiments of the present application relate to a refrigerator, comprising:

[0011] An evaporating dish is used to collect defrost water generated during the refrigeration cycle. An evaporating pipe is arranged in a serpentine shape in the evaporating dish. The evaporating pipe includes an inlet section, a middle section, and an outlet section.
[0012] The evaporating dish is arranged close to the compressor, and the inlet section is connected to the compressor. The outlet section is located above the middle section, and the outlet end extends vertically to connect to an external pipe.
[0013] A plurality of vibration damping blocks, each comprising a vibration damping body, a relief portion, and a clamping portion communicating with the relief portion, wherein both the relief portion and the clamping portion extend along the length of the vibration damping body, and the evaporation pipeline passes through the relief portion and is clamped in the clamping portion;
[0014] A vibration damping block is provided on a section of the evaporation pipeline at the inlet section closest to the bottom wall of the evaporation dish, for isolating the section of the evaporation pipeline from the side wall and the bottom wall of the evaporation dish respectively;
[0015] Another vibration damping block is provided on the middle section, so as to isolate the middle section from the bottom wall of the evaporating dish when the outlet section is pulled up for assembly with the external pipe.
[0016] The advantages or beneficial effects of the above technical solution are as follows: a vibration damping block is provided at the inlet section of the evaporation pipeline, which raises the height of the inlet section from the bottom wall of the evaporation dish, thereby preventing the inlet section from contacting the bottom wall of the evaporation dish due to vibration, and at the same time preventing the evaporation pipeline from contacting the side wall of the evaporation dish due to pulling the evaporation pipeline when piping with the compressor exhaust pipe; another vibration damping block is provided at the middle section, which raises the height of the middle section from the bottom wall of the evaporation dish, thereby preventing the middle section from sinking and contacting the bottom wall due to pulling the outlet section upward when piping with the external pipe; the two vibration damping blocks provided on the evaporation pipeline consume the vibration energy of the evaporation pipeline caused by the vibration of the compressor when the compressor is working, thereby reducing the vibration of the evaporation pipeline, and at the same time, due to the arrangement of the two vibration damping blocks, the evaporation pipeline is prevented from contacting the wall of the evaporation dish, thereby preventing the evaporation pipeline from vibrating and hitting the wall of the evaporation dish to generate resonance noise, thereby ensuring the vibration reduction effect.
[0017] In some embodiments of the present application, the avoidance portion includes:
[0018] a flared portion, which flares outward away from the clamping portion;
[0019] The straight portion is connected through the clamping portion and the flared portion, and the evaporation pipeline passes through the flared portion and the straight portion in sequence and enters the clamping portion.
[0020] The advantages or beneficial effects of the above technical solution are: the flared portion facilitates the installation of the evaporation pipeline, provides operational convenience, and when the evaporation pipeline is installed in the vibration damping block, it can be directly pressed and installed.
[0021] In some embodiments of the present application, a vertical opening height of the straight portion in a direction from the flared portion to the clamping portion is smaller than an outer diameter of the evaporation pipeline.
[0022] The advantages or beneficial effects of the above technical solution are: the vertical opening height of the straight portion is smaller than the outer diameter of the evaporation pipe, thus ensuring that the evaporation pipe can be inserted while preventing the evaporation pipe from sliding and falling from the vibration damping block.
[0023] In some embodiments of the present application, the shape of the clamping portion is circular, and the inner diameter of the clamping portion is smaller than the outer diameter of the evaporation pipeline;
[0024] The vibration damping body is circular in a width direction perpendicular to the length direction thereof, and the clamping portion is formed at the center position of the vibration damping body.
[0025] The advantages or beneficial effects of the above technical solution are: the inner diameter of the clamping part is smaller than the outer diameter of the evaporation pipeline, ensuring a certain amount of compression, ensuring that the vibration damping block can tightly clamp the evaporation pipeline, making the evaporation pipeline not easy to fall.
[0026] In some embodiments of the present application, the vibration damping block is a rubber block.
[0027] The advantages or beneficial effects of the above technical solution are: the rubber material has high damping and high elasticity. High damping can improve the ability to consume energy, and high elasticity has a good effect on vibration reduction, which is convenient for installing the evaporation pipeline and at the same time buffering noise, thereby achieving the effect of reducing noise.
[0028] In some embodiments of the present application, the vibration damping block is a rubber block doped with iron powder.
[0029] The advantages or beneficial effects of the above technical solution are: in addition to rubber, the vibration damping block is also mixed with iron powder, which not only reduces noise but also reduces the production cost of the vibration damping block, and at the same time can also ensure the hardness of the vibration damping block and avoid deformation.
[0030] In some embodiments of the present application, when iron powder is doped into the vibration damping block, the content of the doped iron powder is 20%.
[0031] The advantages or beneficial effects of the above technical solution are: after experimental verification, when the content of doped iron powder is 20%, the cost ratio of rubber to iron powder can reach the optimal level, and the hardness of the vibration damping block is ensured to be moderate, avoiding the problems of difficult installation due to too hard clamping and loose installation due to too soft clamping.
[0032] In some embodiments of the present application, the plurality of vibration damping blocks include:
[0033] Another vibration damping block is arranged at the first bend of the exhaust pipe of the compressor. The first bend passes through the avoidance portion of the other vibration damping block and is clamped in the clamping portion of the other vibration damping block.
[0034] The advantages or beneficial effects of the above technical solution are: when the compressor is working, the refrigerant speed is fast at the first bend of the compressor exhaust pipe, the impact on the pipeline is large, and the vibration is more severe. Therefore, another vibration damping block is arranged at this position to reduce vibration and noise of the pipeline to a greater extent.
[0035] In some embodiments of the present application, a plurality of limiting members are provided on the bottom wall of the evaporating dish, and each limiting member is used to limit the evaporation pipeline.
[0036] The advantages or beneficial effects of the above technical solution are: a limiting member is provided to limit the evaporation pipeline in the evaporation dish and avoid displacement of the evaporation pipeline when the pipe is pulled.

This also allows for convenient access to the evaporator dish's evaporation piping and placement of vibration damping blocks from the lower rear side of the refrigerator. Other features and advantages of the present invention will become more apparent upon reviewing the detailed embodiments of the present invention in conjunction with the accompanying drawings.

[0065] An evaporating dish is provided in the refrigerator to collect the defrost water in the refrigerator. The evaporating pipe is connected to the compressor, which provides the evaporating pipe with the temperature required for evaporation, thereby evaporating the defrost water in the evaporating dish.
[0066] The structure of a refrigerator is described below.
[0067] Figure 1 and Figure 2 This is a schematic diagram of the structure of some embodiments of the refrigerator of this application; Figure 1 and Figure 2 The refrigerator 1 has an approximately rectangular parallelepiped shape, and the appearance of the refrigerator 1 is defined by a box body 100 for defining an internal storage space and a plurality of door bodies 200 for opening or closing the box body 100.
[0068] Among them, reference Figure 2 The door body 200 includes a door body outer shell 210 located on the outside of the box body 100, a door body inner shell 220 located on the inside of the box body 100, an upper end cover 230, a lower end cover 240, and an insulation layer (not shown) located between the door body outer shell 210, the door body inner shell 220, the upper end cover 230, and the lower end cover 240; usually, the insulation layer is filled with foam material.
[0069] The cabinet 100 comprises a shell and an inner container. The inner container is positioned within the shell, creating a space between the two for mounting other refrigerator components and forming a foam insulation layer. The interior of the inner container is vertically divided into a freezer compartment 100A at the bottom and a refrigerator compartment 100B at the top. Each of these compartments can contain independent storage space.
[0070] In detail, the freezing chamber 100A is defined at the lower side of the cabinet 100 and can be selectively covered by a drawer-type freezing chamber door 200A. A space defined above the freezing chamber 100A is partitioned into left and right sides to define the refrigerating chambers 100B, respectively.
[0071] The refrigerating chamber 100B may be selectively opened or closed by a refrigerating chamber door 200B pivotably mounted on the refrigerating chamber 100B.
[0072] Figure 3 A refrigeration system 300 of a refrigerator is shown.
[0073] See also Figure 3 The refrigeration system 300 includes a compressor 310 , a condenser 320 , a throttling device 340 and an evaporator 350 , and a liquid reservoir 360 is provided between the outlet of the freezer compartment evaporator 352 and the air intake of the compressor 310 .
[0074] A compressor cabin is formed between the lower rear side of the box shell and the inner tank, and the compressor 310 and the evaporation dish 410 are arranged in the compressor cabin, that is, the compressor 310 is arranged on the bottom plate 110 of the compressor cabin, and the evaporation dish 410 is arranged on the bottom plate 110 close to the compressor 310 (see Figure 5 ).
[0075] like Figure 3 As shown, in the embodiment of the present application, the evaporator 350 includes a refrigerating chamber evaporator 351 and a freezing chamber evaporator 352 .
[0076] Combine Figure 4 When the refrigerator 1 is in cooling operation, the high-temperature and high-pressure gaseous refrigerant discharged from the compressor 310 passes through the evaporation pipe 420 in the evaporating dish 410 and is then cooled by the condenser 320 to become liquid refrigerant at room temperature. The refrigerant is then divided into two paths by the solenoid valve 330. One path of the refrigerant is throttled and reduced in pressure by the first throttling device 341 (e.g., a first capillary tube) and then enters the refrigerating chamber evaporator 351. The other path of the refrigerant is throttled and reduced in pressure by the second throttling device 342 (e.g., a second capillary tube) and then enters the freezing chamber evaporator 352. The refrigerant pipeline flowing out of the refrigerating chamber evaporator 351 is connected to the pipeline between the second throttling device 342 and the freezing chamber evaporator 352. The liquid refrigerant flowing out of the freezing chamber evaporator 352 flows back into the liquid accumulator 360, and the gaseous refrigerant flows back to the return air port of the compressor 310.
[0077] When the high-temperature and high-pressure gas refrigerant passes through the evaporation pipe 420 , the heat generated evaporates the defrost water in the evaporation dish 410 .
[0078] Among them, when the freezer compartment 100A has a cooling demand, the compressor 310 starts, and the solenoid valve 330 is controlled to introduce the refrigerant into the pipeline where the second throttling device 342 is located. The refrigerant passes through the freezer compartment evaporator 352 and then flows into the return air port of the compressor 310 through the liquid storage tank 360. The cooling of the freezer compartment 100A is achieved through the above-mentioned cycle process.
[0079] When there is a demand for cooling in the cold storage room 100B, the solenoid valve 330 is controlled to introduce the refrigerant into the pipeline where the first throttling device 341 is located. The refrigerant passes through the cold storage room evaporator 351 and the freezer room evaporator 352 in turn, and then passes through the liquid storage tank 360 and flows into the return air port of the compressor 310. The cold storage room 100B is cooled through the above-mentioned cycle process.
[0080] In some embodiments of the present application, when the refrigerator 1 is started, the compressor 310 is in operation. The vibration of the compressor 310 will cause the evaporation pipe 420 in the evaporation dish 410 connected to the exhaust pipe 500 to vibrate, thereby causing the evaporation pipe 420 to contact the wall of the evaporation dish 410, causing the two to produce a large resonance noise, affecting the user experience. Therefore, in order to overcome the resonance noise caused by this contact, see Figure 6 , multiple vibration damping blocks are set on the evaporation pipeline 420.
[0081] In some embodiments of the present application, an evaporating dish assembly 400 for a refrigerator is provided. The evaporating dish assembly 400 includes an evaporating dish 410 , an evaporating pipe 420 , and a plurality of vibration-damping blocks.
[0082] The evaporation dish 410 is as described above and is arranged on the bottom plate 110 of the refrigerator body 100 near the compressor 310 .
[0083] The evaporation line 420 is arranged in a serpentine shape in the evaporation dish 410 to increase the length of the evaporation line 420 and improve the evaporation effect.
[0084] In some embodiments of the present application, the evaporation line 420 includes an inlet section 421 , a middle section 422 , and an outlet section 423 . The inlet section 421 , the middle section 422 , and the outlet section 423 are sequentially connected in a serpentine shape and arranged in the evaporation dish 410 .
[0085] The inlet section 421 is located on one side of the evaporation dish 410 and is connected to the exhaust pipe 500 of the compressor 310 for receiving high-temperature and high-pressure refrigerant discharged from the compressor 310 .
[0086] When piping the inlet section 421, it is necessary to pull it toward the outside of one side of the evaporating dish 410 (the pulling direction is referenced to Figure 6 The inlet section 421 is moved in the direction of the solid arrow, causing the inlet section 421 to contact the side wall of the evaporating dish 410 , and the portion of the inlet section 421 located inside the evaporating dish 410 sinks due to gravity and also contacts the bottom wall of the evaporating dish 410 .
[0087] As a result, the vibration of the compressor 310 is transmitted through the piping, causing the inlet section 421 to resonate and strike the side and bottom walls of the evaporating dish 410, generating resonance noise. Therefore, a vibration damping block (referred to as the first vibration damping block 430 for ease of description) is installed on a portion of the inlet section 421 near the bottom wall of the evaporating dish 410.
[0088] The first vibration damping block 430 is used to dissipate vibration energy transmitted to the inlet section 421 , isolate the inlet section 421 from the side wall of the evaporation dish 410 , and simultaneously elevate the inlet section 421 to isolate the inlet section 421 from the bottom wall of the evaporation dish 410 .
[0089] In some embodiments of this application, see Figure 6 The inlet section 421 is a serpentine design including a first layer 421A and a second layer 421B, so as to increase the length of the inlet section 421 and improve the evaporation effect.
[0090] In some embodiments of the present application, the first vibration damping block 430 is disposed on the second layer 421B of the inlet section 421 closest to the bottom wall. This ensures that the entire inlet section 421 is both away from the side wall of the evaporating dish 410 and elevated relative to the bottom wall, thereby preventing contact and causing resonance and clashing between the two.
[0091] The middle section 422 is located in the middle of the evaporating dish 410, and the outlet section 423 is located above the middle section 422 and has an end along the Figure 6 The middle dotted arrow extends vertically and is used to connect to external piping, for example, a piping connected to the condenser 320 , for leading the refrigerant flowing through the evaporation line 420 to the condenser 320 .
[0092] In some embodiments of the present application, the compressor 310 and the evaporation dish 410 are generally arranged on the bottom plate 110 of the compressor cabin. Therefore, when piping the outlet section 423 of the evaporation dish 410, the outlet section 423 needs to be pulled upward (see the pulling direction for details). Figure 6 The middle section 422 is moved in the direction of the dotted arrow in the middle, causing the middle section 422 to sink and contact the bottom wall of the evaporating dish 410 . Therefore, another vibration damping block (for convenience of description, referred to as the second vibration damping block 440 ) is provided in the middle section 422 .
[0093] The second vibration-damping block 440 can lift the middle section 422 as a whole. When piping the outlet section 423 is connected, the evaporation pipe 420 on the other side of the evaporating dish 410 is also lifted due to the upward pulling force (without contacting the bottom wall of the evaporating dish 410). At the same time, the middle section 422 sinks until it is lifted by the second vibration-damping block 440 and does not contact the bottom wall of the evaporating dish 410, thus preventing the two from resonating and clashing.
[0094] As described above, the first and second vibration-damping blocks 430, 440 are used to elevate the entire evaporation line 420 to isolate the evaporation line 420 from the bottom wall of the evaporation dish 410. Furthermore, the first vibration-damping block 430 also isolates the evaporation line 420 from the side walls of the evaporation dish 410. Therefore, when the compressor 310 is operating, the first and second vibration-damping blocks 430, 440 not only dissipate vibration energy transmitted to the evaporation line 420, but also prevent resonant impact with the wall of the evaporation dish 410, thereby achieving a vibration reduction effect.
[0095] In some embodiments of the present application, other numbers of vibration damping blocks may be provided on the evaporation line 420 to improve the vibration damping effect. However, based on cost and ease of installation, the number of vibration damping blocks is not necessarily better, and should be selected based on actual needs.
[0096] In some embodiments of this application, see Figures 7 to 9 The vibration damping block includes a vibration damping body 431 , an avoidance portion and a clamping portion 432 .
[0097] In some embodiments of the present application, the vibration-damping body 431 is a cylinder, but it can also be designed to have a cross-sectional shape of other shapes.
[0098] The avoidance portion and the clamping portion 432 are both formed on the vibration reduction body 431, and the avoidance portion and the clamping portion 432 are both formed along the length direction of the vibration reduction body 431 (ie Figure 8 The avoidance portion and the clamping portion 432 are connected to each other, and the avoidance portion is connected to the outside. Therefore, the evaporation line 420 is clamped into the clamping portion 432 through the avoidance portion.
[0099] Considering the installation convenience of the vibration damping block, see Figures 7 to 9 The avoidance portion includes a flared portion 433 and a straight portion 434 .
[0100] The flared portion 433 flares outward away from the clamping portion 432 , and the straight portion 434 passes through and connects the clamping portion 432 and the flared portion 433 . When the evaporation line 420 is clamped, the evaporation line 420 passes through the flared portion 433 and the straight portion 434 in sequence and enters the clamping portion 432 to be clamped in the clamping portion 432 .
[0101] The opening angle α of the flared portion 433 toward the outside is approximately between 60° and 70°, which facilitates the convenience of card installation. The flared portion 433 can be directly pressed during card installation.
[0102] The straight portion 434 is located between the flared portion 433 and the clamping portion 432, and is perpendicular to the direction from the flared portion 433 to the clamping portion 432 (see FIG. Figure 9The opening height d (in the W direction shown in FIG) is smaller than the outer diameter of the evaporation pipe 420, so that the evaporation pipe 420 inserted into the clamping portion 432 can be prevented from slipping out.
[0103] Specifically, the size of the vertical opening height d can be considered in consideration of the hardness of the vibration damping body 431. If the vertical opening height is too small, it is not easy to open and install the evaporation pipe 420. If the vertical opening height is too large, there is a risk of the evaporation pipe 420 slipping out and falling.
[0104] For example, if the outer diameter of the evaporation pipe 420 is 4.2 mm, the vertical opening height d can be designed to be 2 mm.
[0105] Likewise, the length along the direction from the flared portion 433 to the clamping portion 432 also needs to be designed appropriately. For example, if the outer diameter of the evaporation pipe 420 is 4.2 mm, the length can be designed to be 5.8 mm.
[0106] In some embodiments of the present application, in order to match the evaporation pipe 420, the clamping portion 432 is circular in shape, and the inner diameter of the clamping portion 432 is smaller than the outer diameter of the evaporation pipe 420. In this way, a certain amount of compression is left in the clamping portion 432 to ensure that the vibration damping block can tightly clamp the evaporation pipe 420, so that the evaporation pipe 420 is not easy to slide and fall.
[0107] In some embodiments of the present application, the vibration reduction body 431 is perpendicular to the length direction (ie Figure 8 The width direction (ie the L direction shown in FIG) Figure 9 The clamping portion 432 is formed at the center of the vibration-damping body 431. Therefore, the vibration-damping block isolates the inlet section 421 of the evaporation pipe 420 from its side wall by a distance equal to the radius of the circular cross-section of the vibration-damping body 431 in its width direction (i.e., W / 2). Furthermore, the distance between the evaporation pipe 420 and the bottom wall of the evaporation dish 410 is also equal to this radius.
[0108] In some embodiments of the present application, the radius can be designed to be 12.5 mm, and the length L can be designed to be 28 mm.
[0109] In some embodiments of the present application, the vibration damping block may be a rubber block.
[0110] Rubber materials have high damping and high elasticity. High damping improves energy dissipation, while high elasticity effectively reduces vibration, facilitating installation of evaporation pipe 420 while also buffering noise and achieving a noise reduction effect. The damping properties of the vibration damping block can also be modified by changing its material, such as butyl rubber, ethylene propylene rubber, and nitrile rubber, thereby adjusting its energy dissipation capacity.
[0111] In some embodiments of the present application, the vibration damping block may be a rubber block doped with iron powder.
[0112] Considering the production cost of the vibration damping block, iron powder is mixed into the vibration damping rubber. Iron powder is cheaper than rubber and can also increase the hardness of the vibration damping block to avoid excessive deformation.
[0113] Although the content of doped iron powder can reduce the cost of the vibration damping block, if the iron powder content is too high, high-adhesion rubber will be required, and the cost will also increase. Therefore, the ratio of the doped iron powder content needs to be considered.
[0114] Through experiments, it is verified that when the content of doped iron powder is 20%, the cost ratio of rubber and iron powder can reach the best level, and the hardness of the vibration damping block can be guaranteed to be moderate, avoiding the problems of difficult installation due to too hard clamping and loose installation due to too soft clamping.
[0115] In some embodiments of this application, see Figure 10 A third vibration damping block 510 is also provided at the first bend of the exhaust pipe 500 of the compressor 310 .
[0116] When the compressor 310 is working, the refrigerant speed is high at the first bend of the exhaust pipe 500 of the compressor 310, which has a great impact on the exhaust pipe 500 and causes more intense vibration. Therefore, another vibration damping block (for the convenience of description, recorded as the third vibration damping block 510) is arranged at this position to consume the vibration energy transmitted to the exhaust pipe 500, thereby reducing the vibration and noise of the exhaust pipe 500 to a greater extent and further reducing the vibration energy transmitted to the evaporation line 420.
[0117] In some embodiments of this application, see Figure 6 A plurality of limiting members 450 are provided on the bottom wall of the evaporating dish 410 , and each limiting member 450 is used to limit the evaporating pipe 420 to prevent the evaporating pipe 420 from shifting when the pipe is pulled.
[0118] Since the collision between the evaporation pipe 420 of the refrigerator evaporation dish assembly 400 and the evaporation dish 410 is only one of the main causes of noise, when the compressor 310 is working, it will vibrate relatively strongly. The evaporation dish 410 is often arranged relatively close to the compressor 310. In this way, the evaporation dish 410 is also prone to vibration, which may cause the evaporation dish 410 to collide with the internal structure of the refrigerator 1 and cause noise problems.
[0119] Therefore, in order to avoid the above problems, the evaporating dish 410 is also subjected to vibration isolation treatment. The evaporating dish 410 is fixed on the bottom plate 110 of the compressor cabin, and a vibration-damping cotton felt (not shown) is provided between the evaporating dish 410 and the bottom plate 110 .
[0120] The provision of the vibration-damping cotton felt allows for soft contact between the evaporating dish 410 and the bottom plate 110 , thereby effectively reducing vibration and noise.
[0121] In addition, the evaporating dish 410 and the bottom plate 110 may be fixed by screws or riveting.
[0122] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.
[0123] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this utility model should be included in the scope of protection of the present utility model. Therefore, the scope of protection of the present utility model should be based on the scope of protection of the claims.
