Description

Technical Field

[0001] The utility model relates to the technical field of refrigerators, in particular to a dust-proof heat dissipation structure and a refrigerator. Background Art

[0002] As an indispensable household appliance in modern families, the core function of the refrigerator is to maintain a low-temperature internal environment through a refrigeration system to preserve food and other items. When the refrigerator is in operation, the heat generated by the refrigeration process needs to be discharged through the heat dissipation system. This heat dissipation process is crucial for the stable operation of the refrigerator. However, during operation, the refrigerator will face the problem of adhesion of pollutants such as dust. These dusts will not only affect the appearance and neatness of the refrigerator, but more importantly, they will hinder the normal operation of the heat dissipation system, resulting in a decrease in heat dissipation efficiency. The decrease in heat dissipation efficiency will directly lead to an increase in the internal temperature of the refrigerator, affecting the refrigeration effect and may even damage the refrigeration system. At the same time, in order to maintain a low internal temperature, the refrigerator has to increase the refrigeration intensity, thereby increasing power consumption. Therefore, in order to ensure the normal operation of the refrigerator, extend its service life, and reduce energy consumption, the refrigerator needs to take effective dust prevention and heat dissipation measures.

[0003] Refrigerators currently on the market mainly use heat sinks for heat dissipation. The heat sink is usually located on the back or bottom of the refrigerator and is an important part of the refrigerator's heat dissipation system. Through the heat sink, the refrigerator can effectively discharge the heat generated during the refrigeration process to the external environment. However, after long-term use, a large amount of dust, dirt and other pollutants will accumulate on the heat sink. These pollutants will cover the surface of the heat sink, forming a thick layer of dust, which hinders the transfer of heat. As the dust layer continues to thicken, the heat dissipation effect will gradually decrease, causing the internal temperature of the refrigerator to rise and the cooling effect to weaken. In addition, the dust accumulated on the heat sink may also cause other problems. For example, the dust layer will hinder air circulation, causing the air temperature around the heat sink to rise, further aggravating the heat dissipation difficulty. At the same time, the dust layer may also become a breeding ground for microorganisms such as bacteria and mold, posing a threat to the sanitary environment inside the refrigerator.

[0004] Chinese patent document CN110887304A discloses a built-in two-door refrigerator, comprising a built-in refrigerator body, a heat dissipation shell mounted on the bottom of the built-in refrigerator body, the heat dissipation shell being a rectangular shell, a dust screen mounted at the heat dissipation shell port, and a decontamination and anti-blocking assembly mounted at the heat dissipation shell port for removing oil and dust from the dust screen. However, the following defects still exist during implementation:

[0005] Although the device in the above-mentioned document can wipe the dustproof mesh cover back and forth with a sponge brush to effectively remove blocked impurities, the device in the above-mentioned document cannot clean the dust accumulated on the heat sink. As a result, after long-term use, a large amount of dust, dirt and other pollutants will accumulate on the heat sink. These pollutants will cover the surface of the heat sink, forming a thick dust layer, which will hinder the transfer of heat and then affect the normal use of the heat sink. Utility Model Content

[0040] The present invention is further described in detail below with reference to the embodiments:

[0041] Example 1

[0042] like Figure 1 - Figure 6 As shown, the utility model provides a dust-proof heat dissipation structure and a refrigerator, including a refrigerator body 1, a filter screen plate 2, a cleaning assembly 5 and a storage assembly 7; the filter screen plate 2 is fixedly connected to a connecting block 21 on one side close to the storage assembly 7, a fan 23 is provided in the middle of the connecting block 21, and the fan 23 is used for heat dissipation, the lower part of the refrigerator body 1 is fixedly connected to a partition 3, the middle part of the lower end of the partition 3 is fixedly connected to a heat sink 4, and a driving assembly 6 is provided at the lower end of the partition 3, and the driving assembly 6 is used to drive the cleaning assembly 5 to move, and the cleaning assembly 5 includes a support seat 51, and a plurality of mounting grooves 52 are opened on the upper part of the support seat 51, and the inner cavities of the plurality of mounting grooves 52 are all slidably connected to the dust removal assembly 53.

[0043] In this embodiment, the air delivered to the inner cavity of the refrigerator body 1 by the fan 23 can be filtered through the filter plate 2, thereby reducing the amount of impurities such as external dust entering the inner cavity of the refrigerator body 1, thereby reducing the amount of external dust accumulated on the blades of the heat sink 4. The fan 23 can dissipate heat from the inner cavity of the refrigerator body 1 and the heat sink 4. While dissipating heat, the dust cleaned by the cleaning component 5 can be blown to the storage component 7. The storage component 7 can collect the dust cleaned from the blades of the heat sink 4 by the cleaning component 5 to prevent the dust from falling on the blades of the heat sink 4 again. The opposite surfaces of the two adjacent dust removal components 53 are in contact with the blades of the heat sink 4. Therefore, when the driving component 6 drives the cleaning component 5 to move, the dust removal component 53 can be driven to clean the dust on the blades of the heat sink 4, thereby reducing the amount of dust on the blades of the heat sink 4.

[0044] Example 2

[0045] like Figure 7 、 Figure 10 and Figure 11 As shown, on the basis of embodiment 1, the utility model provides a technical solution: preferably, the driving assembly 6 includes a connecting rod 63, a threaded rod 64 and two connecting plates 61, the upper ends of the two connecting plates 61 are fixedly connected to the lower end of the partition 3, the lower ends of the two connecting plates 61 are fixedly connected to the connecting block three 62, the connecting rod 63 is fixedly connected to the two adjacent connecting blocks three 62, the threaded rod 64 is rotatably connected to the adjacent connecting block three 62, the threaded rod 64 is rotatably connected to the support plate one 65, the upper end of the support plate one 65 is fixedly connected to the lower end of the adjacent connecting plate 61, one side of the support plate one 65 is fixedly connected to the support plate two 68, the middle of the support plate two 68 is fixedly connected to the motor 69, and the threaded rod 64 is close to One side of the support plate 2 68 is fixedly connected with a gear 1 66, and the output shaft of the motor 69 is fixedly connected with a gear 2 67. The gear 1 66 is meshed with the adjacent gear 2 67. The connecting block 2 54 on the same side is slidably connected with the connecting rod 63. The connecting block 2 54 on the same side is threadedly connected with the threaded rod 64. The opposite surfaces of the two connecting plates 61 are provided with a slide groove 611. The inner cavity of the slide groove 611 on the same side is slidably connected with the slider 56. The slider 56 is T-shaped. The upper part of the support seat 51 is symmetrically fixed with the slider 56. The upper part of the support seat 51 is symmetrically fixed with the connecting block 2 54. The upper part of the support seat 51 is symmetrically fixed with a number of limit assemblies 55. The inner cavity of the limit assemblies 55 is communicated with the inner cavity of the adjacent mounting groove 52.

[0046] In this embodiment, when it is necessary to clean the dust on the blades of the heat sink 4, the motor 69 is first controlled by the controller to operate, and then the output shaft of the motor 69 is used to drive the gear 2 67 to rotate, and then the gear 2 67 is used to engage the adjacent gear 1 66, thereby driving the gear 1 66 to rotate, and then when the gear 1 66 rotates, it will drive the threaded rod 64 to rotate. Since one of the connecting blocks 2 54 is threadedly connected to the threaded rod 64, when the threaded rod 64 rotates, it will drive the connecting block 2 54 to move, and then the entire cleaning assembly 5 can be driven to move through the connecting block 2 54. When the cleaning assembly 5 moves, it will drive the slider 56 to slide in the inner cavity of the slide groove 611. Since the sponge block 533 is in contact with the surface of the blades of the heat sink 4, when the cleaning assembly 5 moves, it can drive the sponge block 533 to clean the surface of the blades of the heat sink 4, thereby cleaning the dust on the surface of the blades of the heat sink 4.

[0047] Example 3

[0048] like Figure 12 As shown, based on Example 2, the present invention provides a technical solution: preferably, the storage assembly 7 includes a storage box 71, the storage box 71 is rotatably connected to the refrigerator body 1, and the upper end of the storage box 71 is fixedly connected to a filter plate 2 72.

[0049] In this embodiment, when cleaning the dust on the surface of the heat sink 4 blades, the controller controls the fan 23 to run, and then the fan 23 can be used to blow the dust cleaned from the heat sink 4 blades by the cleaning component 5 to the storage component 7. Under the interception effect of the filter plate 2 72, the dust in the wind will be intercepted. Then, when the fan 23 stops running, the dust intercepted by the filter plate 2 72 will fall into the inner cavity of the storage box 71, and then the dust is collected by the storage box 71 to prevent the dust from being again in the inner cavity of the refrigerator body 1 or floating in the outside world. Since the storage box 71 is rotatably connected to the refrigerator body 1, when the position limit of the storage component 7 is released, the storage component 7 can be rotated in the direction away from the refrigerator body 1, and then the dust in the inner cavity of the storage box 71 can be cleaned.

[0050] Example 4

[0051] like Figure 8 and Figure 9As shown, on the basis of Example 3, the utility model provides a technical solution: preferably, the dust removal component 53 includes a docking plate 531, and a limiting groove 532 is symmetrically opened on the upper part of the docking plate 531, and a sponge block 533 is fixedly connected to the side of the docking plate 531 close to the heat sink 4, and the docking plate 531 is slidably connected to the inner cavity of the adjacent installation groove 52, and the limiting component 55 includes an outer shell 551, and the outer shell 551 is fixedly connected to the support seat 51, and the inner cavity of the outer shell 551 is communicated with the inner cavity of the adjacent installation groove 52, and the inner cavity of the outer shell 551 is slidably connected to a clamping block 553, and the inner cavity of the outer shell 551 is fixedly connected to a spring 552, and the side of the spring 552 close to the clamping block 553 is fixedly connected to the clamping block 553.

[0052] In this embodiment, when the sponge block 533 needs to be cleaned or the dust removal assembly 53 needs to be replaced, the storage assembly 7 is first rotated in the direction away from the refrigerator body 1, and then the driving assembly 6 drives the cleaning assembly 5 to move toward the storage assembly 7. When the cleaning assembly 5 moves to the appropriate position, the staff then slides the dust removal assembly 53 upward from the inner cavity of the installation slot 52 to separate the dust removal assembly 53 from the installation slot 52, and then slides the new dust removal assembly 53 into the inner cavity of the installation slot 52. During the installation process, the dust removal assembly 53 applies a force to the block 553, and then drives the block 553 to move outside. When the block 553 contacts the inner cavity of the limiting groove 532, the elastic force of the spring 552 will drive the spring 552 to stretch, and then push the block 553 to move in the inner cavity of the outer shell 551 toward the inner cavity of the limiting groove 532, and then push the outer surface of the block 553 to contact the inner cavity of the limiting groove 532, so that the position of the dust removal component 53 in the inner cavity of the installation groove 52 can be limited by the cooperation between the block 553 and the limiting groove 532, thereby completing the replacement of the dust removal component 53.

[0053] The working principle of the dust-proof heat dissipation structure and the refrigerator will be described in detail below.

[0054] like Figure 1 - Figure 12As shown, when the dust on the blades of the heat sink 4 needs to be cleaned, the motor 69 is first controlled by the controller to operate, and then the output shaft of the motor 69 is used to drive the gear 2 67 to rotate, and then the gear 2 67 is used to mesh with the adjacent gear 1 66, so as to drive the gear 1 66 to rotate, and then when the gear 1 66 rotates, it will drive the threaded rod 64 to rotate. Since one of the connecting blocks 2 54 is threadedly connected to the threaded rod 64, when the threaded rod 64 rotates, it will drive the connecting block 2 54 to move, and then the entire cleaning assembly 5 can be driven to move through the connecting block 2 54. When the cleaning assembly 5 moves, it will drive the slider 56 to slide in the inner cavity of the slide groove 611. Since the sponge block 533 is in contact with the surface of the blades of the heat sink 4, when the cleaning assembly 5 moves, it can drive the sponge block 533 to clean the surface of the blades of the heat sink 4, thereby cleaning the dust on the surface of the blades of the heat sink 4.

[0055] When cleaning the dust on the surface of the heat sink 4 blades, the controller controls the fan 23 to run, and then the fan 23 can be used to blow the dust cleaned from the heat sink 4 blades by the cleaning assembly 5 to the storage assembly 7, and the dust in the wind is intercepted by the second filter plate 72. Then, when the fan 23 stops running, the dust intercepted by the second filter plate 72 will fall into the inner cavity of the storage box 71, and then the dust is collected by the storage box 71 to prevent the dust from being again in the inner cavity of the refrigerator body 1 or floating to the outside. Since the storage box 71 is rotatably connected to the refrigerator body 1, when the position limit of the storage assembly 7 is released, the storage assembly 7 can be rotated in a direction away from the refrigerator body 1, so as to facilitate cleaning of the dust in the inner cavity of the storage box 71.

[0056] When the sponge block 533 needs to be cleaned or the dust removal assembly 53 needs to be replaced, the storage assembly 7 is first rotated in the direction away from the refrigerator body 1, and then the driving assembly 6 drives the cleaning assembly 5 to move toward the storage assembly 7. When the cleaning assembly 5 moves to the appropriate position, the staff then slides the dust removal assembly 53 upward from the inner cavity of the installation slot 52 to separate the dust removal assembly 53 from the installation slot 52, and then slides the new dust removal assembly 53 into the inner cavity of the installation slot 52. During the installation process, the dust removal assembly 53 applies a force to the card block 553, and then drives the card block 553 to move in the outer shell 551. When the clamping block 553 contacts the inner cavity of the limiting groove 532, the spring 552 is driven to stretch under the elastic force of the spring 552, and then the clamping block 553 is pushed to move in the inner cavity of the shell 551 toward the inner cavity of the limiting groove 532, and then the outer surface of the clamping block 553 is pushed to contact the inner cavity of the limiting groove 532. Therefore, through the cooperation between the clamping block 553 and the limiting groove 532, the position of the dust removal component 53 in the inner cavity of the installation groove 52 can be limited, thereby completing the replacement of the dust removal component 53.

[0057] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
