- the refrigeration device 100 provided by this embodiment of the present invention may be a refrigerator, a freezer, or a wine cooler.
- This embodiment of the present invention exemplarily illustrates some possible implementations by using a household refrigerator as an example, but these implementations are not limited to being applicable to only the household refrigerator. It can be expected that the following implementations can also be used in the freezer or the wine cooler, to achieve the same technical effect.
- FIG. 1 shows a partial elevation view of a refrigerator
- FIG. 3 and FIG. 4 show partial exploded views of a refrigerator from different perspectives, in which a structure of a machine compartment 2 is illustrated
- FIG. 5 shows a rear view of a machine compartment 2, in which a rear wall 7 and some cables and pipes in the machine compartment 2 are hidden
- FIG. 6 illustrates an air flow path in a machine compartment 2, positions of a condenser 4, a fan 5, and a compressor 3, and positions of an air inlet 11 and an air outlet 12 from a top view;
- the refrigeration device 100 includes a main body 1, and the machine compartment 2 of the refrigeration device 100 is disposed below the main body 1.
- the machine compartment 2 is used for accommodating components, for example, the compressor 3, the condenser 4, and the fan 5 of the refrigeration device 100.
- the machine compartment 2 is a relatively closed space, and may be formed by enclosing a front wall 13, a bottom wall 6, the rear wall 7, and a first side wall 8 and a second side wall 9 of the refrigeration device 100 that are disposed opposite to each other.
- Both the condenser 4 and the compressor 3 are located between the first side wall 8 and the second side wall 9, the condenser 4 is closer to the first side wall 8 than the compressor 3, and the compressor 3 is closer to the second side wall 9 than the condenser 4.
- the refrigeration device 100 is further provided with a first weather strip 10, and the first weather strip 10 is connected to the bottom wall 6 and extends in a front-rear direction.
- the bottom wall 6 is divided into two zones by the first weather strip 10 in a left-right direction.
- One zone is a first bottom wall portion 61 between the first side wall 8 and the first weather strip 10
- the other zone is a second bottom wall portion 62 between the second side wall 9 and the first weather strip 10.
- the rear wall 7 may also be divided into a first rear wall portion 71 and a second rear wall portion 72 respectively corresponding to the first bottom wall portion 61 and the second bottom wall portion 62.
- Air inlets 11 are disposed on the first side wall 8 and the first rear wall portion 71, and external air may enter the machine compartment 2 from the air inlets 11.
- the second bottom wall portion 62 is provided with an air outlet 12, and the air in the machine compartment 2 may flow out of the machine compartment 2 from the air outlet 12.
- a negative pressure zone is formed in the machine compartment 2. Due to action of a pressure difference, the external air flows into the machine compartment 2 from the air inlets 11, successively flows through the condenser 4 and the compressor 3, and then flows out from the air outlet 12, to take part of heat in the machine compartment 2 away.
- the distances between the air inlets 11 and the air outlet 12 are longer, and cold air can come into full contact with components in the machine compartment 2, to take more heat away.
- hot air that flows out of the air outlet 12 can flow less to the air inlets 11, and a temperature of air that flows into the machine compartment 2 is lower, thereby providing a better cooling effect for the compressor 3; and the first weather strip 10 also blocks the hot air that flows out of the air outlet 12 from flowing to the air inlets 11 to some extent, and the temperature of the air that flows into the machine compartment 2 is lower.
- a first air inlet 111 may be disposed on only the first side wall 8.

- the first air inlet 111 may be disposed on the first side wall 8
- the second air inlet 112 may be disposed on the first rear wall portion 71.
- a larger quantity or a larger area of the air inlets 11 indicates a larger amount of air entering the machine compartment 2 and a better cooling effect provided for the compressor 3.
- the air inlets 11 face the condenser 4.
- the air entering the machine compartment 2 directly flows to the condenser 4, a path thereof is straight and short, and a loss of pressure is small, thereby accelerating air circulation, and facilitating cooling of the compressor 3.
- the air outlet 12 is an elongated air outlet 12. In the left-right direction, one end of the air outlet extends to a position between the first weather strip 10 and the condenser 4, and the other end of the air outlet extends to a position between the compressor 3 and the second side wall 9.
- Such a configuration ensures to a relatively large extent that the air outlet 12 has a wider distribution range, pressure distribution of the air in the machine compartment 2 is more uniform, and cold air and hot air are easier to mix uniformly and take heat away.
- the air outlet 12 has a part located between the first weather strip 10 and the condenser 4 and a part located between the compressor 3 and the second side wall 9.
- the air outlet 12 may alternatively be located only between the first weather strip 10 and the condenser 4, or between the compressor 3 and the second side wall 9.
- the air outlet 12 is located between the front wall 13 and the bottom wall 6.
- the air inlets 11 are located on the first side wall 8 and/or the first rear wall portion 71, while the air outlet 12 is located in the front of the second bottom wall portion 62, so that the distances between the air inlets 11 and the air outlet 12 are longer, and a better cooling effect is provided for the compressor 3.
- Cold air has a tortuous flow path between the condenser 4 and the air outlet 12, and therefore can come into better contact with the components in the machine compartment 2, to take more heat away.
- the air inlets 11 may be obtained by spacing the bottom wall 6 and the front wall 13, and a gap may be used as the air outlet 12.
- the refrigeration device further includes a second weather strip 14.
- the second weather strip 14 extends in the left-right direction, and is located behind the air outlet 12.
- the second weather strip 14 may block the hot air that flows out of the air outlet 12 from flowing backward and flowing into the machine compartment 2 from the second air inlet 112, or from flowing out of the first side wall 8 and flowing into the machine compartment 2 from the first air inlet 111. That is to say, the second weather strip 14 may also improve the cooling efficiency of the compressor 3.
- the second weather strip 14 is connected to a lower edge of the rear wall 7 and protrudes downward.
- the second weather strip 14 may also be connected to the bottom wall 6.
- the second weather strip 14 may extend from the first rear wall portion 71 to the second rear wall portion 72; or extend from the first bottom wall portion 61 to the second bottom wall portion 62.
- the air inlet 11 is provided with a conical air duct 21, and the air duct 21 has an exterior size greater than an interior size.
- the machine compartment 2 is divided into two relatively independent zones by the condenser 4, that is, a first zone 15 between the first side wall 8 and the condenser 4, and a second zone 16 between the condenser 4 and the second side wall 9.
- the compressor 3 and the fan 5 are located in the second zone 16.
- the compressor 3 and the fan 5 are larger in volume and occupy larger spaces in the machine compartment 2.
- the machine compartment 2 is further provided with a water collection box 17 used for collecting condensed water or defrosting water, and the water collection box 17 is also located in the second zone 16.
- the water collection box 17 is such disposed that the external air can flow into the first zone 15 smoothly, and then flow into the second zone 16, thereby facilitating air circulation.
- the water collection box 17 is disposed on a top portion of the compressor 3, so that cooled air can come into contact with an outer surface of the compressor 3 more smoothly, to take more heat away.
- the fan 5 is located between the condenser 4 and the compressor 3. With such a configuration, when the fan runs, a negative pressure zone is formed in the first zone 15. Especially, when large-volume components are located in the second zone 16, the external cold air can flow into the machine compartment 2 more smoothly, so that the compressor 3 has a better heat dispassion effect.
- FIG. 7 shows a partial enlarged view of a cross-section at a position A in FIG. 1 ; and FIG. 8 and FIG. 9 respectively show partial enlarged views at a position B in FIG. 3 from different perspectives.
- the refrigeration device 100 further includes an air intake structure 18, the air intake structure 18 includes an air duct support 19, and the first air inlet 111 is formed on the air duct support 19.
- the air duct support 19 is integrally formed, a hole-shaped air duct 21 penetrating through the air duct support is disposed on the air duct support 19, and the air duct 21 may be used as one part of the first air inlet 111.
- the air duct support 19 can improve plasticity of shapes of the air inlets 11, and the air inlets 11 may be designed and processed into a shape more conducive to air circulation.
- the air duct 21 is conical, and has an exterior size less than an interior size.
- the first side wall 8 is further provided with a through hole 20, and a position of the through hole 20 corresponds to a position of the air duct 21, so that air passages inside and outside the machine compartment 2 communicate with each other.
- the refrigeration device 100 further includes a first clamping structure 22, and the first clamping structure 22 is used for clamping the air duct support 19 to the first side wall 8.
- the air intake structure 18 is easy to be mounted onto the first side wall 8, so that the air duct 21 and the first side wall 8 fit better.
- the air intake structure 18 may alternatively be located on the rear wall 7 to cooperate with the rear wall 7, to form the second air inlet 112.
- the implementation process of this variant embodiment is the same as that of the previous embodiment, and achieves a technical effect equivalent to that of the previous embodiment, so the details will not be repeated herein.
- the first air inlet 111 will be described as an example below, and the description of the first air inlet 111 also applies to the solution of the second air inlet 112.
- a bottom portion of the first side wall 8 is provided with a flange facing the interior of the machine compartment 2, and the flange is provided with a clamping hole 221.
- a slot facing the first side wall 8 is formed on the air duct support 19, and a first clamping buckle 222 is disposed in the slot. After the flange is inserted into the slot, at least one part of the first clamping buckle 222 is clamped in the clamping hole 221, thereby restricting movement of the air duct support 19 relative to the first side wall 8, to complete clamping of the air duct support 19 and the first side wall 8. That is to say, the first clamping structure 22 includes the above clamping hole 221 and first clamping buckle 222.
- the refrigeration device further includes a cover plate 23, and the cover plate 23 is located outside the first air inlet 111, to prevent insects, mice, or other sundries from entering the machine compartment 2 from the air inlets 11.

- the first side wall 8 is mostly a sheet metal part, which, limited by the shape and material, is difficult to form a good clamping structure.
- the clamping structure on the air duct support 19 can be provided with a larger degree of freedom and is easier to form, and the cover plate 23 can be easily mounted on and firmly clamped to the air duct support.

- An embodiment of the present invention provides a
refrigeration device 100. - The
refrigeration device 100 provided by this embodiment of the present invention may be a refrigerator, a freezer, or a wine cooler. - This embodiment of the present invention exemplarily illustrates some possible implementations by using a household refrigerator as an example, but these implementations are not limited to being applicable to only the household refrigerator. It can be expected that the following implementations can also be used in the freezer or the wine cooler, to achieve the same technical effect.
- Referring to
FIG. 1 to FIG. 6 ,FIG. 1 shows a partial elevation view of a refrigerator;FIG. 3 andFIG. 4 show partial exploded views of a refrigerator from different perspectives, in which a structure of a machine compartment 2 is illustrated;FIG. 5 shows a rear view of a machine compartment 2, in which arear wall 7 and some cables and pipes in the machine compartment 2 are hidden; andFIG. 6 illustrates an air flow path in a machine compartment 2, positions of acondenser 4, afan 5, and acompressor 3, and positions of anair inlet 11 and anair outlet 12 from a top view; - The
refrigeration device 100 includes amain body 1, and the machine compartment 2 of therefrigeration device 100 is disposed below themain body 1. The machine compartment 2 is used for accommodating components, for example, thecompressor 3, thecondenser 4, and thefan 5 of therefrigeration device 100. - The machine compartment 2 is a relatively closed space, and may be formed by enclosing a
front wall 13, abottom wall 6, therear wall 7, and afirst side wall 8 and asecond side wall 9 of therefrigeration device 100 that are disposed opposite to each other. - Both the
condenser 4 and thecompressor 3 are located between thefirst side wall 8 and thesecond side wall 9, thecondenser 4 is closer to thefirst side wall 8 than thecompressor 3, and thecompressor 3 is closer to thesecond side wall 9 than thecondenser 4. - The
refrigeration device 100 is further provided with afirst weather strip 10, and thefirst weather strip 10 is connected to thebottom wall 6 and extends in a front-rear direction. - The
bottom wall 6 is divided into two zones by thefirst weather strip 10 in a left-right direction. One zone is a firstbottom wall portion 61 between thefirst side wall 8 and thefirst weather strip 10, and the other zone is a secondbottom wall portion 62 between thesecond side wall 9 and thefirst weather strip 10. - The
rear wall 7 may also be divided into a firstrear wall portion 71 and a secondrear wall portion 72 respectively corresponding to the firstbottom wall portion 61 and the secondbottom wall portion 62. -
Air inlets 11 are disposed on thefirst side wall 8 and the firstrear wall portion 71, and external air may enter the machine compartment 2 from theair inlets 11. - The second
bottom wall portion 62 is provided with anair outlet 12, and the air in the machine compartment 2 may flow out of the machine compartment 2 from theair outlet 12. - After the
fan 5 runs, a negative pressure zone is formed in the machine compartment 2. Due to action of a pressure difference, the external air flows into the machine compartment 2 from theair inlets 11, successively flows through thecondenser 4 and thecompressor 3, and then flows out from theair outlet 12, to take part of heat in the machine compartment 2 away. - With the above layout, the distances between the
air inlets 11 and theair outlet 12 are longer, and cold air can come into full contact with components in the machine compartment 2, to take more heat away. In addition, hot air that flows out of theair outlet 12 can flow less to theair inlets 11, and a temperature of air that flows into the machine compartment 2 is lower, thereby providing a better cooling effect for thecompressor 3; and thefirst weather strip 10 also blocks the hot air that flows out of theair outlet 12 from flowing to theair inlets 11 to some extent, and the temperature of the air that flows into the machine compartment 2 is lower. - As a variant example, a
first air inlet 111 may be disposed on only thefirst side wall 8. - As a variant example, a
second air inlet 112 may be disposed on only the firstrear wall portion 71. - As an embodiment, the
first air inlet 111 may be disposed on thefirst side wall 8, and thesecond air inlet 112 may be disposed on the firstrear wall portion 71. A larger quantity or a larger area of theair inlets 11 indicates a larger amount of air entering the machine compartment 2 and a better cooling effect provided for thecompressor 3. - In a possible implementation, the
air inlets 11 face thecondenser 4. The air entering the machine compartment 2 directly flows to thecondenser 4, a path thereof is straight and short, and a loss of pressure is small, thereby accelerating air circulation, and facilitating cooling of thecompressor 3. - In a possible implementation, the
air outlet 12 is anelongated air outlet 12. In the left-right direction, one end of the air outlet extends to a position between thefirst weather strip 10 and thecondenser 4, and the other end of the air outlet extends to a position between thecompressor 3 and thesecond side wall 9. Such a configuration ensures to a relatively large extent that theair outlet 12 has a wider distribution range, pressure distribution of the air in the machine compartment 2 is more uniform, and cold air and hot air are easier to mix uniformly and take heat away. - As a variant example, there may be a plurality of
air outlets 12. Theair outlet 12 has a part located between thefirst weather strip 10 and thecondenser 4 and a part located between thecompressor 3 and thesecond side wall 9. - As a variant example, the
air outlet 12 may alternatively be located only between thefirst weather strip 10 and thecondenser 4, or between thecompressor 3 and thesecond side wall 9. - In a possible implementation, the
air outlet 12 is located between thefront wall 13 and thebottom wall 6. In this way, theair inlets 11 are located on thefirst side wall 8 and/or the firstrear wall portion 71, while theair outlet 12 is located in the front of the secondbottom wall portion 62, so that the distances between theair inlets 11 and theair outlet 12 are longer, and a better cooling effect is provided for thecompressor 3. Cold air has a tortuous flow path between thecondenser 4 and theair outlet 12, and therefore can come into better contact with the components in the machine compartment 2, to take more heat away. - Exemplarily, the
air inlets 11 may be obtained by spacing thebottom wall 6 and thefront wall 13, and a gap may be used as theair outlet 12. - In a possible implementation, the refrigeration device further includes a
second weather strip 14. Thesecond weather strip 14 extends in the left-right direction, and is located behind theair outlet 12. Thesecond weather strip 14 may block the hot air that flows out of theair outlet 12 from flowing backward and flowing into the machine compartment 2 from thesecond air inlet 112, or from flowing out of thefirst side wall 8 and flowing into the machine compartment 2 from thefirst air inlet 111. That is to say, thesecond weather strip 14 may also improve the cooling efficiency of thecompressor 3. - As shown in the accompanying drawings, the
second weather strip 14 is connected to a lower edge of therear wall 7 and protrudes downward. - As a variant example, the
second weather strip 14 may also be connected to thebottom wall 6. - To reduce that the hot air re-flows into the machine compartment 2 from the rear or side as much as possible, the
second weather strip 14 may extend from the firstrear wall portion 71 to the secondrear wall portion 72; or extend from the firstbottom wall portion 61 to the secondbottom wall portion 62. - In a possible implementation, the
air inlet 11 is provided with aconical air duct 21, and theair duct 21 has an exterior size greater than an interior size. With such a configuration, after entering the machine compartment 2, external cold air may diffuse rapidly and mix uniformly with the hot air in the machine compartment 2, to take more heat away. - In a possible implementation, the machine compartment 2 is divided into two relatively independent zones by the
condenser 4, that is, afirst zone 15 between thefirst side wall 8 and thecondenser 4, and asecond zone 16 between thecondenser 4 and thesecond side wall 9. Further, thecompressor 3 and thefan 5 are located in thesecond zone 16. Thecompressor 3 and thefan 5 are larger in volume and occupy larger spaces in the machine compartment 2. By disposing thecompressor 3 and thefan 5 in thesecond zone 16, the external air can flow into thefirst zone 15 smoothly, and then flow into thesecond zone 16, thereby facilitating air circulation. - Still further, the machine compartment 2 is further provided with a
water collection box 17 used for collecting condensed water or defrosting water, and thewater collection box 17 is also located in thesecond zone 16. Thewater collection box 17 is such disposed that the external air can flow into thefirst zone 15 smoothly, and then flow into thesecond zone 16, thereby facilitating air circulation. - Still further, the
water collection box 17 is disposed on a top portion of thecompressor 3, so that cooled air can come into contact with an outer surface of thecompressor 3 more smoothly, to take more heat away. - Still further, the
fan 5 is located between thecondenser 4 and thecompressor 3. With such a configuration, when the fan runs, a negative pressure zone is formed in thefirst zone 15. Especially, when large-volume components are located in thesecond zone 16, the external cold air can flow into the machine compartment 2 more smoothly, so that thecompressor 3 has a better heat dispassion effect. - Referring to
FIG. 7 to FIG. 9 below,FIG. 7 shows a partial enlarged view of a cross-section at a position A inFIG. 1 ; andFIG. 8 and FIG. 9 respectively show partial enlarged views at a position B inFIG. 3 from different perspectives. - In a possible embodiment, the
refrigeration device 100 further includes an air intake structure 18, the air intake structure 18 includes anair duct support 19, and thefirst air inlet 111 is formed on theair duct support 19. Preferably, theair duct support 19 is integrally formed, a hole-shapedair duct 21 penetrating through the air duct support is disposed on theair duct support 19, and theair duct 21 may be used as one part of thefirst air inlet 111. Compared with the conventional ventilation implemented by digging holes on thefirst side wall 8, theair duct support 19 can improve plasticity of shapes of theair inlets 11, and theair inlets 11 may be designed and processed into a shape more conducive to air circulation. - Further, the
air duct 21 is conical, and has an exterior size less than an interior size. - The
first side wall 8 is further provided with a throughhole 20, and a position of the throughhole 20 corresponds to a position of theair duct 21, so that air passages inside and outside the machine compartment 2 communicate with each other. - The
refrigeration device 100 further includes afirst clamping structure 22, and thefirst clamping structure 22 is used for clamping theair duct support 19 to thefirst side wall 8. In this way, the air intake structure 18 is easy to be mounted onto thefirst side wall 8, so that theair duct 21 and thefirst side wall 8 fit better. - Those skilled in the art can understand that the previous embodiment is exemplary description made by using the
first air inlet 111 as an example. - As a variant embodiment, the air intake structure 18 may alternatively be located on the
rear wall 7 to cooperate with therear wall 7, to form thesecond air inlet 112. The implementation process of this variant embodiment is the same as that of the previous embodiment, and achieves a technical effect equivalent to that of the previous embodiment, so the details will not be repeated herein. Thefirst air inlet 111 will be described as an example below, and the description of thefirst air inlet 111 also applies to the solution of thesecond air inlet 112. - In a possible implementation, a bottom portion of the
first side wall 8 is provided with a flange facing the interior of the machine compartment 2, and the flange is provided with aclamping hole 221. A slot facing thefirst side wall 8 is formed on theair duct support 19, and afirst clamping buckle 222 is disposed in the slot. After the flange is inserted into the slot, at least one part of thefirst clamping buckle 222 is clamped in theclamping hole 221, thereby restricting movement of theair duct support 19 relative to thefirst side wall 8, to complete clamping of theair duct support 19 and thefirst side wall 8. That is to say, thefirst clamping structure 22 includes theabove clamping hole 221 andfirst clamping buckle 222. - In a possible implementation, the refrigeration device further includes a
cover plate 23, and thecover plate 23 is located outside thefirst air inlet 111, to prevent insects, mice, or other sundries from entering the machine compartment 2 from theair inlets 11. - Further, the refrigeration device further includes a
second clamping structure 24, and thesecond clamping structure 24 is used for clamping thecover plate 23 to theair duct support 19. Compared with the solution of connecting thecover plate 23 to thefirst side wall 8 in the prior art, this embodiment is easier to be implemented. In the prior art, thefirst side wall 8 is mostly a sheet metal part, which, limited by the shape and material, is difficult to form a good clamping structure. In this embodiment, the clamping structure on theair duct support 19 can be provided with a larger degree of freedom and is easier to form, and thecover plate 23 can be easily mounted on and firmly clamped to the air duct support. - Further, a clamping
claw 241 is disposed on thecover plate 23, asecond clamping buckle 242 that can cooperate with the clampingclaw 241 is disposed on theair duct support 19, and thesecond clamping structure 24 includes the clampingclaw 241 and thesecond clamping buckle 242. When thecover plate 23 is close to thefirst side wall 8, the clampingclaw 241 penetrates through the throughhole 20 to cooperate with thesecond clamping buckle 242 to clamp thecover plate 23 to theair duct support 19. With such a configuration, thecover plate 23 is mounted conveniently and firmly. - It should be noted that, the above embodiments are described with reference to a state of the
refrigeration device 100 during normal use. By using a household refrigerator as an example, the front-rear direction is a depth direction of the refrigerator; and the left-right direction is a width direction of the refrigerator. Referring to the accompanying drawings, the front is a direction the same as a y direction, the rear is a direction opposite to the y direction, and the left-right direction may be an x direction or a direction opposite to the x direction. - Although specific implementations have been described above, these implementations are not intended to limit the scope of this application, even if only one implementation is described with respect to specific features. The feature example provided in this application is intended to be illustrative rather than limiting, unless otherwise stated. During specific implementation, according to an actual requirement, in a technically feasible case, the technical features of one or more dependent claims may be combined with the technical features of the independent claims, and the technical features from the corresponding independent claims may be combined in any appropriate way instead of using just specific combinations listed in the claims.
- The various specific implementations described above and shown in the accompanying drawings are only used to illustrate this application, but are not all of this application. Any variation made by a person of ordinary skill in the art to this application within the scope of the basic technical concept of this application shall fall within the protection scope of this application.
