Description

Technical Field

[0001] The invention relates to the field of refrigerators, and in particular to a refrigerator dust removal device and a refrigerator. Background Art

[0002] With the improvement of modern living standards, consumers have increasingly stronger requirements for the aesthetics and practicality of their home environment. The optimized design and efficient use of kitchen space have become one of the focuses of home decoration. Under this trend, built-in refrigerators have been favored by consumers because they can perfectly integrate with cabinets, not only saving space, but also improving the overall aesthetics of the kitchen. The design feature of built-in refrigerators lies in their compact installation method, which usually requires the distance between the refrigerator and the cabinet to be minimized to increase the volume ratio of the kitchen. To achieve this goal, the traditional heat dissipation method of refrigerators, that is, heat dissipation through the back or sides, can no longer meet the needs. Therefore, bottom heat dissipation technology came into being. Bottom heat dissipation technology uses an external condenser to replace the built-in condenser, and uses a condensing fan to force convection heat exchange, forming a two-way circulation heat dissipation system with left air outlet at the bottom and right air inlet at the back. This innovative design effectively solves the contradiction between refrigerator heat dissipation and cabinet space limitations, so that there is no need to reserve additional heat dissipation space on the sides and top of the refrigerator, which not only maintains the beauty and tidiness of the kitchen, but also ensures the long-term stable operation of the refrigerator.

[0003] However, despite the many advantages brought by bottom heat dissipation technology, it is also accompanied by new challenges. Since the external condenser is directly exposed to the kitchen environment, dust, oil smoke and other impurities in the air are easily accumulated on the fins of the condenser. If it is not cleaned for a long time, the fins will be blocked, which seriously affects the heat exchange efficiency, thereby causing the refrigerator's refrigeration performance to decline, energy consumption to increase, and even serious faults such as system shutdown and compressor overheating. These problems not only affect the service life of the refrigerator, but also bring inconvenience and economic losses to users. The traditional condenser dust removal method is to completely disassemble the condenser for cleaning, or to set a filter at the condenser and remove the filter for cleaning. These two cleaning methods are not only cumbersome, time-consuming and labor-intensive, but also particularly complicated for built-in refrigerators. Since the refrigerator fits tightly with the cabinet, disassembling the refrigerator for condenser cleaning and removing the filter at the condenser requires the refrigerator to be removed from the cabinet, which not only requires additional space and tools, but may also damage the cabinet or the refrigerator itself. When reinstalling after cleaning, it is difficult to ensure that the refrigerator is accurately centered, affecting the appearance and convenience of use. Therefore, the maintenance of built-in refrigerator condensers has become an industry pain point, and an efficient and convenient condenser dust removal solution is urgently needed. Summary of the invention

[0042] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0043] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0044] With the improvement of modern living standards, consumers have increasingly stronger requirements for the aesthetics and practicality of their home environment. The optimized design and efficient use of kitchen space have become one of the focuses of home decoration. Under this trend, built-in refrigerators have been favored by consumers because they can perfectly integrate with cabinets, not only saving space, but also improving the overall aesthetics of the kitchen. The design feature of built-in refrigerators lies in their compact installation method, which usually requires the distance between the refrigerator and the cabinet to be minimized to increase the volume ratio of the kitchen. To achieve this goal, the traditional heat dissipation method of refrigerators, that is, heat dissipation through the back or sides, can no longer meet the needs. Therefore, bottom heat dissipation technology came into being. Bottom heat dissipation technology uses an external condenser to replace the built-in condenser, and uses a condensing fan to force convection heat exchange, forming a two-way circulation heat dissipation system with left air outlet at the bottom and right air inlet at the back. This innovative design effectively solves the contradiction between refrigerator heat dissipation and cabinet space limitations, so that there is no need to reserve additional heat dissipation space on the sides and top of the refrigerator, which not only maintains the beauty and tidiness of the kitchen, but also ensures the long-term stable operation of the refrigerator.

[0045] However, despite the many advantages brought by bottom heat dissipation technology, it is also accompanied by new challenges. Since the external condenser is directly exposed to the kitchen environment, dust, oil smoke and other impurities in the air are easily accumulated on the fins of the condenser. If it is not cleaned for a long time, the fins will be blocked, which seriously affects the heat exchange efficiency, thereby causing the refrigerator's refrigeration performance to decline, energy consumption to increase, and even serious faults such as system shutdown and compressor overheating. These problems not only affect the service life of the refrigerator, but also bring inconvenience and economic losses to users. The traditional condenser dust removal method is to completely disassemble the condenser for cleaning, or to set a filter at the condenser and remove the filter for cleaning. These two cleaning methods are not only cumbersome, time-consuming and labor-intensive, but also particularly complicated for built-in refrigerators. Since the refrigerator fits tightly with the cabinet, disassembling the refrigerator for condenser cleaning and removing the filter at the condenser requires the refrigerator to be removed from the cabinet, which not only requires additional space and tools, but may also damage the cabinet or the refrigerator itself. When reinstalling after cleaning, it is difficult to ensure that the refrigerator is accurately centered, affecting the appearance and convenience of use. Therefore, the maintenance of built-in refrigerator condensers has become an industry pain point, and an efficient and convenient condenser dust removal solution is urgently needed.

[0046] like Figure 1-2As shown, the present invention proposes a dust removal device for a refrigerator, including a filter track 51, a first winding portion 41, a second winding portion 42, a door gear 31 and a gear transmission assembly.

[0047] The filter track 51 is arranged on the refrigerator body 3 and covers the air outlet on the side of the refrigerator body 3. A filter 52 is arranged inside the filter track 51 and can move along the filter track 51. The filter covers the air outlet of the condenser 56 for heat dissipation. A brush body is arranged on the filter track 51 to clean the filter 52 when the filter 52 moves. The first winding part 41 is arranged in the refrigerator body 3 near the refrigerator door and is used to wind one end of the filter 52. The second winding part 42 is arranged near one end of the filter track 51 and is used to wind the other end of the filter 52. The door gear 121 is arranged on the refrigerator door and surrounds the hinge shaft 23 of the door and rotates with the door. The power output gear 22 of the gear transmission assembly is meshed with the gear 31 of the first winding part 41, and its power input gear 21 is meshed with the door gear 121 when the refrigerator door is rotated to open or closed. When the refrigerator door is opened or closed, the position of the filter 52 is changed by the cooperation of the gear transmission assembly to clean the filter 52.

[0048] The device automatically triggers the movement and cleaning process of the filter 52 by the action of opening or closing the refrigerator door, without the need for the user to manually perform cleaning operations, thereby improving the convenience and efficiency of use. The filter track 51 is arranged on the refrigerator body 3, covering the air vents on the side of the body 3, which not only ensures the normal ventilation of the air vents, but also effectively utilizes the space on the side of the refrigerator for the installation and cleaning of the filter 52, and does not occupy other space. Since the filter 52 can be automatically moved and cleaned by the brush body, the user does not need to frequently disassemble the filter 52 for manual cleaning, which reduces the difficulty and cost of maintenance. By automatically cleaning the filter 52, the air circulation and cleanliness inside the refrigerator can be maintained, which helps to improve the refrigeration efficiency of the refrigerator, reduce energy consumption, and also helps to extend the service life of the refrigerator.

[0049] like Figure 1-2 As shown, specifically, a door stopper 12 is provided on the door of the refrigerator, and a hinge plate 25 is provided on the body 3 of the refrigerator.

[0050] like Figure 5 As shown, the door stopper 12 is arranged at the bottom of the door opening side of the box door, and a mounting hole is provided on the door stopper 12 for rotationally connecting with the hinge plate 25. A door-actuating gear 121 with a geared portion facing downward is provided around the mounting hole on the door stopper 12.

[0051] like Figure 3-4As shown, the hinge plate 25 is in the shape of a plate, one part of which is installed at the bottom of the door opening side of the refrigerator body 3, and the other part extends to the bottom of the door stop 12. The hinge plate 25 is provided with a plurality of mounting positions, one of which is used to install the hinge shaft 23. One end of the hinge shaft 23 is arranged on the mounting position of the hinge plate 25, and the other end extends into the mounting hole of the door stop 12, so that the door stop 12 and the hinge plate 25 are rotatably connected for opening and closing the refrigerator door.

[0052] like Figure 8 As shown, the filter track 51 is arranged at the air outlet on the side of the refrigerator body 3, and a filter 52 is arranged in the filter track 51. The filter 52 can move horizontally along the track, and a brush body in contact with the filter 52 is arranged in the filter track 51 toward the direction of the filter 52, so that when the filter 52 moves in the track, the brush body can clean the dust on the filter 52.

[0053] like Figure 6-8 As shown, the first winding portion 41 is arranged in the refrigerator body 3 near the door opening side. The first winding portion 41 includes a gear 31 and a storage rod connected to the gear 31. The storage rod is vertically arranged and connected to the gear 31. The storage rod is used to wind the filter 52.

[0054] The second winding portion 42 is disposed at the other end of the filter screen 52 . The second winding portion 42 is specifically a clockwork mechanism that can recover kinetic energy.

[0055] like Figure 3-4 As shown, the gear 31 assembly includes a power output gear 22 arranged on the hinge plate 25 and a power input gear 21 sleeved on the hinge shaft 23, and the power input gear 21 is provided with a first toothed portion for toothed engagement with the door driving gear 121 and a second toothed portion for toothed engagement with the power output gear 22. The gear 31 of the first winding portion 41 is toothed engagement with the power output gear 22.

[0056] When the box door is closed, the power input gear 21 of its gear transmission assembly meshes with the door-moving gear 121, and the power output gear 22 meshes with the power output gear 22, thereby driving the gear 31 of the first winding portion 41 to rotate, thereby driving the storage rod to rotate. The storage rod is initially connected to one end of the filter 52. When the storage rod rotates, part of the filter 52 will be wound on the storage rod, that is, the filter 52 moves, and the brush will brush away the dust on the filter 52.

[0057] When the door is opened, the door gear 121 and the power input gear 21 are no longer engaged, and the power output gear 22 no longer transmits. Due to the nature of the spring, the second winding portion 42 uses the stored power to bring the filter 52 wound on the storage rod back to its original position.

[0058] like Figure 4As shown, in a further embodiment, the hinge shaft 23 of the refrigerator is located between the power input gear 21 and the door-moving gear 121 and is provided with a first spring 24; the two ends of the first spring are respectively connected to the power input gear and the hinge plate, the first spring 24 is extended, the power input gear 21 and the door-moving gear 121 are meshed, and the power input gear 21 and the power output gear 22 are meshed. At this time, when the refrigerator door 1 moves, the gear transmission assembly will cause the first winding portion 41 to rotate, so that the filter 52 is wound on the first winding portion 41; the first spring 24 retracts, the power input gear 21 and the door-moving gear 121 are separated, and the power input gear 21 and the power output gear 22 are separated. At this time, the refrigerator door 1 moves, the filter 52 will not be wound on the first winding portion 41, and due to the characteristics of the second winding portion 42, the filter 52 originally wound on the first winding portion 41 will be restored to its original position.

[0059] The introduction of the first spring 24 makes the movement control of the filter 52 more flexible. When the spring is extended, the power input gear 21 is meshed with the door gear 121 and the power output gear 22. At this time, the movement of the refrigerator door 1 can drive the gear transmission assembly, thereby rotating the first winding part 41 to achieve the winding of the filter 52. When the spring retracts, the meshing relationship between the gears 31 is released, and the movement of the refrigerator door 1 no longer affects the position of the filter 52. The filter 52 returns to its original position due to the characteristics of the second winding part 42 (such as the return of the spring or the reversal of the motor, etc.).

[0060] like Figure 1-2 As shown, in a further embodiment, the door-moving gear 121 is made of an electromagnet. When the door-moving gear 121 is energized, the power input gear is attracted due to the electromagnetic suction force, and the first spring 24 is extended. When the door-moving gear 121 is de-energized, the first spring 24 retracts.

[0061] By turning the gate gear 121 on and off, the meshing and separation of the gate gear 121 with the power input gear 21 and the power output gear 22 can be precisely controlled, thereby achieving precise control of the winding and release of the filter screen 52.

[0062] It should be noted that the filter screen 52 has a partial surplus that surrounds the first winding portion 41 and the second winding portion 42 , so the filter screen 52 can surround the first winding portion 41 within the surplus range.

[0063] like Figure 1-2As shown, in this embodiment, when the refrigerator door is opened, the door gear 121 is powered off, the door gear 31 and the power output gear 22 are not meshed with the power input gear 21, and the power stored in the second winding portion 42 brings the filter 52 wrapped around the first winding portion 41 back to its original position. When the refrigerator door is closed, the door gear 121 is powered on, the door gear 121 and the power output gear 22 are meshed with the power input gear 21, thereby driving the first winding portion 41 to rotate, so that part of the filter 52 will be wound on the storage rod. When the filter 52 is wound on the first winding portion 41 and restored to its original position, the position moves, and the brush body on the filter track 51 cleans the filter 52, and it is no longer necessary to move the refrigerator to clean the filter 52.

[0064] like Figure 4 As shown, in a further embodiment, a stopper 27 is further provided on the hinge plate 25, and a second spring 28 is sleeved on the stopper 27. The stopper 27 can move up and down on the hinge plate 25. When the power input gear 21 is not engaged with the door gear 121 and the power output gear 22, and the filter 52 does not need to return to its original position, the second spring 28 extends and the stopper 27 clamps the power output gear 22.

[0065] When the power input gear 21 is not meshed with the gate gear 121 and the power output gear 22, and the filter screen 52 does not need to return to its original position, the second spring 28 stretches to make the stopper 27 clamp the power output gear 22. This design can prevent the power output gear 22 from rotating freely without control, thereby enhancing the stability of the entire system.

[0066] like Figure 4 As shown, specifically, the stopper 27 includes: a first connecting rod and a second connecting rod, the first connecting rod and the second connecting rod are vertically movably mounted on the hinge plate 25, and the tops thereof are connected by a cross bar, and a second spring 28 is arranged on the first connecting rod and / or the second connecting rod, and a hook is provided at one end of the cross bar for clamping the power output gear 22. The power output gear 22 is made of an electromagnet, and when the power output gear 22 is energized, the second spring 28 stretches. When the power input gear 21 is not engaged with the door gear 121 and the power output gear 22, and the filter screen 52 does not need to return to its original position, the power output gear 22 is energized, and the stopper 27 moves upward due to the electromagnetic characteristics, and the spring stretches, so that the hook portion of the stopper 27 clamps the power output gear 22.

[0067] When the power output gear 22 is energized, its electromagnetic characteristics attract the anti-rotation member 27 (particularly the crossbar and the hook portion) to move upward, while extending the second spring 28. This mechanism ensures that when the filter screen 52 does not need to move, the power output gear 22 can be accurately locked to prevent it from accidentally rotating.

[0068] When the filter 52 needs to be moved, the power supply of the power output gear 22 only needs to be disconnected, the electromagnetic attraction disappears, the retraction force of the second spring 28 causes the stopper 27 to drop, and the hook disengages from the power output gear 22, thereby allowing the gear 31 to rotate freely.

[0069] like Figure 7 As shown, in a further embodiment, a dust removal box is provided at the bottom of the refrigerator. The dust removal box is rectangular and is arranged below the filter 52 for collecting dust cleaned from the filter 52. The dust removal box is provided with a handle extending to the front of the refrigerator door.

[0070] The design of the dust box 53 allows the dust cleaned from the filter 52 to be collected centrally, preventing the dust from being scattered inside the refrigerator or in the surrounding environment, thereby simplifying the cleaning process. The presence of the handle allows the user to easily pull out the dust box from the bottom of the refrigerator for cleaning or replacement without moving the refrigerator or performing complicated disassembly operations.

[0071] In a further embodiment, a temperature sensor is provided at the refrigerator condenser 56. When the temperature value detected by the temperature sensor is greater than the preset temperature value, it indicates that the current temperature of the condenser 56 is too high, the ventilation is poor, and the filter 52 has too much dust. At this time, the control module controls the output gear 22 to cut off the power, and the second spring 28 contracts, so that the filter 52 wound on the first winding part 41 is restored to the original position, the filter 52 moves, and the brush body on the filter track 51 cleans the filter 52.

[0072] The temperature sensor can monitor the temperature of the condenser 56 in real time. When the temperature is too high, it indicates that the filter 52 may have accumulated too much dust, affecting the ventilation effect. At this time, the system can automatically trigger the cleaning mechanism, and the second spring 28 is contracted by power failure, driving the filter 52 to return to the original position, and the brush on the filter track 51 is used to clean the filter 52.

[0073] The filter track 51 includes a first track portion and a second track portion. The first track portion covers the air outlet on the side of the box body 3. The second track portion is perpendicular to the first track portion and is located inside the box body 3. The middle portion of the filter 52 is located inside the first track portion, one end portion is located inside the second track portion, and the other end portion extends from the box body 3 to the first winding portion 41.

[0074] In a further embodiment, the hinge plate 25 is further provided with an adjustment foot 26 for supporting the box body 3, and the adjustment foot 26 is threadedly connected to the hinge plate 25. The height of the box body 3 is changed by adjusting the position of the threaded connection.

[0075] The present invention also provides a refrigerator using the refrigerator dust removal device of the present application.

[0076] Compared with the prior art, the present invention proposes a dust removal device for a refrigerator, comprising: a filter track 51, a first winding portion 41, a second winding portion 42, a door gear 31 and a gear transmission assembly, wherein the power output gear 22 of the gear transmission assembly meshes with the gear 31 of the first winding portion, and the power input gear 21 meshes with the door gear 121 when the refrigerator door is rotated to open or closed, so that the filter 52 is wound on the first winding portion, the filter 52 moves, and the brush body on the filter track 51 removes dust from the filter 52. The device automatically triggers the movement and cleaning process of the filter 52 through the action of opening or closing the refrigerator door, and does not require the user to manually perform the cleaning operation, thereby improving the convenience and efficiency of use.
