Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, and in particular to a dust removal device and a refrigerator. Background Art

[0002] As society progresses and consumer spending continues to rise, so too do their expectations for kitchen decor. Refrigerators and other household appliances have become indispensable. Built-in refrigerators, for example, are designed to integrate seamlessly with cabinets, with relatively close spacing between them. To maximize the refrigerator's volume ratio, the back of the refrigerator is placed close to the cabinet. This prevents heat dissipation from the back and sides, forcing the appliance to rely on bottom cooling. However, after long-term operation, bottom cooling can cause dust to accumulate on the condenser fins. If left uncleaned, these fins can become clogged, reducing the condenser's heat exchange efficiency. In severe cases, this can lead to system shutdowns and excessive compressor temperatures.

[0003] Conventional condenser dust removal requires complete disassembly and cleaning. This cumbersome process results in long maintenance cycles for the condenser, which often leaves the condenser operating below optimal condition for extended periods, reducing its heat exchange efficiency. This is particularly true for built-in refrigerators, which require users to remove the refrigerator from the cabinet, making it difficult to align the refrigerator with the cabinet when repositioning it. Consequently, dust removal in the compressor compartment of built-in refrigerators has long been a major pain point in the industry. Utility Model Content

[0056] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0057] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0058] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip or a change in posture or a change in motion, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will subsequently be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein will be interpreted accordingly.

[0059] like Figure 1As shown, in order to integrate the refrigerator 200 with the cabinet 300, the distance between the refrigerator 200 and the cabinet is relatively small, and the back of the refrigerator 200 is close to the cabinet or wall 300. The back and sides of the refrigerator 200 cannot dissipate heat, and can only dissipate heat from the bottom. The built-in refrigerator 200 uses an external condenser 203 instead of a built-in condenser 203. The external condenser 203 can reduce the load on the cabinet. The compressor compartment 201 at the bottom of the refrigerator 200 is separated into two chambers with the condenser fan 202 as the boundary. The condenser fan 202 is used to force convection heat exchange, forming a two-way circulation heat dissipation system with air outlet on the left at the bottom and air intake on the right at the rear. No heat dissipation space is required on the sides or top, achieving good heat dissipation effect. However, after long-term operation of this structure, dust in the air will accumulate on the fins of the condenser 203. If it is not cleaned for a long time, it will become dirty and clogged, causing the heat exchange efficiency of the condenser 203 to decrease. In severe cases, it may cause system shutdown and excessive temperature of the compressor 204. Conventional methods for dust removal from condenser 203 require complete disassembly and cleaning of the condenser 203. This cumbersome disassembly and cleaning process results in prolonged maintenance cycles for the condenser 203, which in turn causes the condenser 203 to remain in suboptimal working condition for extended periods, resulting in reduced heat exchange efficiency. This is particularly true for built-in refrigerators 200, requiring users to remove the refrigerator 200 from the cabinet in order to disassemble and clean the condenser 203, a time-consuming and labor-intensive process. Furthermore, it can be difficult to align the refrigerator 200 with the cabinet when repositioning it.

[0060] In order to solve the technical problem that it is difficult to clean the condenser of the existing refrigerator, the process of disassembling and cleaning the condenser is cumbersome, resulting in a long maintenance cycle for the user for the condenser, affecting the heat exchange efficiency of the condenser, the present application provides a dust removal device and a refrigerator. When dust removal is required, the user does not need to move the refrigerator out of the cabinet. The cleaning process is simple and convenient, saving time and effort. At the same time, it can ensure the heat exchange efficiency of the condenser, thereby improving the long-term operation reliability of the refrigerator.

[0061] Figures 2 to 3 The present application provides a dust removal device 1, which is arranged at the bottom of a refrigerator 100. The refrigerator 100 includes a box body 2, a condenser 3 and a condensing fan 4. The bottom of the box body 2 is provided with a accommodating cavity 21, and the condenser 3 and the condensing fan 4 are arranged in the accommodating cavity 21. The dust removal device 1 includes a support member 11 and a filter body 12. The support member 11 is arranged around the circumference of the condenser 3 and the condensing fan 4; it should be noted that the support member 11 is arranged around the circumference of the condenser 3 and the condensing fan 4, which means that the support member 11 can be arranged in a ring around the circumference of the condenser 3 and the condensing fan 4, or can be arranged in a square around the circumference of the condenser 3 and the condensing fan 4, or can be arranged in an L-shape around the two adjacent sides of the condenser 3 and the condensing fan 4 (such as Figure 5 ), no specific limitation is given here.

[0062] A part of the filter body 12 is movably arranged on the support 11, and the other part of the filter body 12 is movably arranged on the box body 2, so that a barrier space for blocking external dust is formed between the filter body 12 and the box body 2; the filter body 12 has a starting end 1201 and an end 1202 arranged relatively to each other, and the starting end 1201 of the filter body 12 passes through the side of the box body 2 toward the user; the cleaning member 13 is arranged on the support 11 and abuts against the filter body 12; wherein, when the starting end 1201 of the filter body 12 is subjected to external force, the filter body 12 moves away from the accommodating chamber 21 relative to the box body 2, and the filter body 12 continues to contact with the cleaning member 13 during the movement relative to the support 11 to remove dust accumulated on the filter body 12.

[0063] For the convenience of explanation and understanding, the side of the cabinet 2 facing the user is referred to as the "front of the refrigerator 100", and the side of the cabinet 2 facing away from the user is referred to as the "back of the refrigerator 100". During the continuous refrigeration process of the refrigerator 100, due to the forced convection heat exchange of the condensing fan 4, a large amount of external air flows into the accommodating cavity 21 at the bottom of the cabinet 2. The support 11 is arranged around the condenser 3 and the condensing fan 4. A part of the filter body 12 is movably arranged on the support 11, and another part of the filter body 12 is movably arranged on the cabinet 2, so that a barrier space is formed between the filter body 12 and the cabinet 2. The filter body 12 and the cabinet 2 can block external dust from entering the barrier space, thereby avoiding dust accumulation on the condenser 3 and the condensing fan 4 and ensuring the heat exchange efficiency of the condenser 3. However, during operation, dust will gradually accumulate on the filter body 12. The starting end 1201 of the filter body 12 extends from the side of the housing 2 facing the user. That is, the starting end 1201 of the filter body 12 passes through the side of the housing 2 and is exposed at the front of the refrigerator 100. When cleaning the filter body 12, the user can stand at the front of the refrigerator 100 to operate. The user grasps the starting end 1201 of the filter body 12 and pulls it outward, causing the starting end 1201 of the filter body 12 to move relative to the housing 2 away from the accommodating cavity 21 under the action of an external force. During the movement of the filter body 12 relative to the support member 11, the filter body 12 continuously contacts the cleaning member 13. Due to the friction between the filter body 12 and the cleaning member 13, dust accumulated on the filter body 12 is removed by the cleaning member 13. Compared to the prior art, when dust removal is required, the user does not need to move the refrigerator 100 out of the cabinet, making the cleaning process simple, convenient, time-saving and labor-saving. At the same time, dust accumulation on the fins of the condenser 3 is prevented, ensuring the heat exchange efficiency of the condenser 3, thereby improving the long-term operational reliability of the refrigerator 100.

[0064] In addition, if Figure 4As shown, the filter body 12 can be a single piece made of a flexible material, giving the filter body 12 a certain degree of flexibility. When the support member 11 is arranged in a ring around the condenser 3 and the condenser fan 4, the filter body 12 can be bent into a ring relative to the support member 11; when it is arranged in a square around the condenser 3 and the condenser fan 4, the filter body 12 can be bent into a square relative to the support member 11; when it is arranged in an L-shape around the adjacent two sides of the condenser 3 and the condenser fan 4, the filter body 12 can be bent into an L-shape relative to the support member 11. Of course, the filter body 12 can also be set to other shapes, which will not be repeated here.

[0065] In some exemplary embodiments, Figure 5 and Figure 6 As shown, the support member 11 includes a first frame body 111 and a second frame body 112, which are staggered in the first horizontal direction and connected to each other. The first frame body 111 is arranged on the side of the condensing fan 4 away from the condenser 3, and the second frame body 112 is arranged on the side of the condenser 3 away from the user; the filter body 12 includes a first filter body 121 and a second filter body 122 connected to the first filter body 121. In the initial state of the filter body 12, the first filter body 121 is connected to the first frame body 111, and the second filter body 122 is connected to the second frame body 112.

[0066] Alternatively, the first horizontal direction may be the X direction shown in the figure. It is understood that, in the initial state of the filter body 12, that is, when the starting end 1201 of the filter body 12 is not subjected to external force, the first filter body 121 is connected to the first frame body 111, and the second filter body 122 is connected to the second frame body 112. Since the first frame body 111 is arranged on the side of the condenser fan 4 away from the condenser 3, that is, the first frame body 111 is arranged around the outer periphery of the condenser fan 4, the first filter body 121 on the first frame body 111 separates the condenser fan 4 from the compressor 6, and the second frame body 112 is arranged on the side of the condenser 3 away from the user, that is, the second frame body 112 is arranged behind the condenser 3 and close to the back of the refrigerator 100, so that the second filter body 122 of the second frame body 112 separates the condenser 3 from the external space of the refrigerator 100. A barrier space is formed between the first filter body 121 , the second filter body 122 and the box body 2 , which can prevent external dust from entering the barrier space, thereby avoiding dust accumulation in the condenser 3 and the condensing fan 4 and ensuring the heat exchange performance of the condenser 3 .

[0067] Furthermore, the side of the second frame 112 away from the first frame 111 extends along the second horizontal direction close to the box 2, so that the second filter 122 can be as close to the box 2 as possible to block external dust. Optionally, the second horizontal direction is the Y direction shown in the figure.

[0068] In some exemplary embodiments, Figure 5 As shown, the first frame 111 and the second frame 112 are both provided with a first slide groove 113, and the first filter body 121 and the second filter body 122 are both slidably connected to the first slide groove 113. Specifically, the first slide groove 113 is provided on the inner side wall of the first frame 111, and the first slide groove 113 is provided in the horizontal direction.

[0069] The specific structure in which the first filter body 121 and the second filter body 122 are both slidably connected to the first slide groove 113 can be set as: the outer side walls of the first filter body 121 and the second filter body 122 are directly embedded in the first slide groove 113, so that the first filter body 121 and the second filter body 122 can slide along the first slide groove 113; or, the outer side walls of the first filter body 121 and the second filter body 122 are provided with sliders slidably connected to the first slide groove 113, so that the first filter body 121 and the second filter body 122 can slide along the first slide groove 113.

[0070] It can be understood that the first filter body 121 can be slidably connected to the first slide groove 113 on the first frame body 111, so that the first filter body 121 can reciprocate in the horizontal direction relative to the first frame body 111; the first filter body 121 can be slidably connected to the first slide groove 113 on the second frame body 112, so that the first filter body 121 can reciprocate in the horizontal direction relative to the second frame body 112; the second filter body 122 can be slidably connected to the first slide groove 113 on the second frame body 112, so that the second filter body 122 can reciprocate in the horizontal direction relative to the second frame body 112. When the filter body 12 needs to be cleaned, the user holds the starting end 1201 of the filter body 12 and pulls it outward, so that the starting end 1201 of the filter body 12 moves relative to the box body 2 away from the accommodating chamber 21 under the action of external force, thereby driving the second filter body 122 to move relative to the second frame body 112, and at the same time driving the first filter body 121 to move relative to the first frame body 111, so that the first filter body 121 and the second filter body 122 contact with the cleaning member 13. Under the action of the friction force between the first filter body 121 and the second filter body 122 and the cleaning member 13, the accumulated dust on the first filter body 121 and the second filter body 122 is removed by the cleaning member 13.

[0071] In one embodiment, Figure 5 and Figure 6As shown, the first frame 111 may include a plurality of first transverse plates 1111 and a plurality of first longitudinal plates 1112, the first transverse plates 1111 and the first longitudinal plates 1112 are crisscrossed and sequentially connected end to end to form the first frame 111, the vertical direction may be the Z direction shown in the figure, the length direction of the first transverse plate 1111 is parallel to the X direction, the side wall of the first transverse plate 1111 is provided with a first slide groove 113 along the X direction, and the length direction of the first longitudinal plate 1112 is parallel to the Z direction; the second frame 112 may include a plurality of second transverse plates 1121 and a plurality of second longitudinal plates 1122, the plurality of second transverse plates 1121 and the second longitudinal plates 1122 are crisscrossed and sequentially connected end to end to form the second frame 112, the length direction of the second transverse plate 1121 is parallel to the Y direction, the side wall of the second transverse plate 1121 is provided with a first slide groove 113 along the Y direction, and the length direction of the second longitudinal plate 1122 is parallel to the Z direction. Then, when the starting end 1201 of the filter body 12 moves away from the accommodating chamber 21 relative to the box body 2 under the action of external force, the second filter body 122 can move along the Y direction on the first slide groove 113, and the first filter body 121 can first move along the X direction on the first slide groove 113, pass through the first frame body 111, and then move along the Y direction.

[0072] In some exemplary embodiments, the first frame 111 and the second frame 112 are provided with second chutes 114 for the filter body 12 to slide through, and the second chutes 114 are arranged in a vertical direction. Specifically, the second chutes 114 are arranged in a vertical direction on the sidewalls of the first vertical plate, and the second chutes 114 are arranged in a vertical direction on the sidewalls of the second vertical plate. Then, when the starting end 1201 of the filter body 12 moves away from the accommodating chamber 21 relative to the housing 2 under the action of an external force, the second filter body 122 moves along the first chutes 113 of the second frame 112 in the Y direction and passes through the second chutes 114 of the second frame 112. The first filter body 121 moves along the first chutes 113 of the first frame 111 in the X direction and passes through the second chutes 114 of the first frame 111 and the second chutes 114 of the second frame 112. By providing the second sliding groove 114 , the stability of the movement of the filter body 12 can be improved, thereby facilitating the removal of dust accumulated on the filter body 12 during cleaning.

[0073] In some exemplary embodiments, Figure 5As shown, the cleaning member 13 includes a brush 131, which is disposed on the second chute 114 and abuts against the filter body 12. As the second filter body 122 passes through the second chute 114, the friction between the second filter body 122 and the brush 131 causes the brush 131 to brush away accumulated dust on the second filter body 122. Similarly, as the first filter body 121 passes through the second chute 114, the friction between the first filter body 121 and the brush 131 causes the brush 131 to brush away accumulated dust on the first filter body 121, thereby cleaning the filter body 12. This saves time and effort, and is convenient for the user.

[0074] Alternatively, as Figure 5 As shown, the second frame 112 includes a reinforcing plate 1123, the two ends of which are respectively connected to the second cross plate 1121. The reinforcing plate 1123 is provided with a second chute 114, and a brush 131 is disposed within the second chute 114 of the reinforcing plate 1123. The provision of the reinforcing plate 1123 can improve the structural strength of the second frame 112, thereby improving the smoothness of the movement of the filter body 12 relative to the second frame 112. At the same time, the brush 131 on the reinforcing plate 1123 can be used to clean dust accumulated on the filter body 12, further improving the cleaning effect.

[0075] In some exemplary embodiments, Figure 6 and Figure 7 As shown, the filter body 12 also includes a third filter 123. The first filter 121, the second filter 122, and the third filter 123 are sequentially connected. The housing 2 has a foam layer 22, and the foam layer 22 located on the side of the housing 2 is provided with a through groove 23. The third filter 123 is slidably connected to the through groove 23. During installation, the starting end 1201 of the filter body 12 is sequentially passed through the second slide groove 114 of the first frame and the second slide groove 114 of the second frame, and then through the through groove 23 provided on the foam layer 22 on the side of the housing 2, and then exposed to the front of the refrigerator 100. This saves installation space. Since the third filter 123 is disposed within the foam layer of the housing 2, dust accumulation on the third filter 123 is prevented, reducing the dust accumulation area of ​​the filter body 12, thereby saving the user cleaning time.

[0076] Furthermore, if Figure 6 and Figure 7 As shown, the starting end 1201 of the filter body 12 is located on the side of the third filter body 123 away from the second filter body 122. A first bent portion 125 is provided at the starting end 1201 of the filter body 12. The first bent portion 125 abuts against the side of the housing 2 facing the user. In the initial state, the first bent portion 125 abuts against the side of the housing 2 facing the user, providing a positioning function. When cleaning the filter body 12, the user grasps the first bent portion 125 and pulls it outward, making it easier for the user to apply force.

[0077] In some exemplary embodiments, Figure 6 As shown, the first filter body 121 and the second filter body 122 are provided with an array of heat dissipation holes 124. The heat dissipation holes 124 can be arranged in a circular, square, diamond, honeycomb, or other shapes, without specific limitation. The array distribution of the heat dissipation holes 124 may include a circular array of the heat dissipation holes 124 on the first filter body 121 and the second filter body 122, or a rectangular array of the heat dissipation holes 124 on the first filter body 121 and the second filter body 122, without specific limitation in this application. Heat generated by the condenser 3 can be dissipated to the exterior of the housing 2 through the heat dissipation holes 124, ensuring effective heat dissipation of the condenser 3 and thus improving the long-term operational reliability of the condenser 3. The size of the heat dissipation holes 124 is designed according to actual needs. While ensuring effective heat dissipation of the condenser 3, it can also prevent external dust from entering the isolation space, preventing dust accumulation in the condenser 3 and the condenser fan. It should be noted that since the third filter body 123 is disposed within the foam layer of the housing 2, no additional heat dissipation holes 124 are required.

[0078] In some exemplary embodiments, Figure 6 As shown, the end 1202 of the filter body 12 is provided with a reel 126, which is provided on the side of the support 11 near the condensing fan 4. The reel 126 has a first state in which it is reeled relative to the support 11 and a second state in which it is unfolded relative to the support 11. In the second state, the reel 126 automatically returns the filter body 12 to its original position under the action of its own restoring force. When the filter body 12 needs to be cleaned, the user grasps the beginning 1201 of the filter body 12 and pulls it outward, so that the beginning 1201 of the filter body 12 moves relative to the housing 2 away from the accommodating chamber 21 under the action of an external force, thereby driving the filter body 12 to move relative to the support 11. The filter body 12 and the cleaning member 13 come into contact with each other. Under the action of the friction between the filter body 12 and the cleaning member 13, the dust accumulated on the filter body 12 is removed by the cleaning member 13. During the movement of the filter body 12, the winding portion 126 continues to extend, and the winding portion 126 switches from a first state of being wound relative to the support member 11 to a second state of being unfolded relative to the support member 11. The winding portion 126 stores energy during the extension process. After the dust removal is completed, the winding portion 126 automatically reels under the action of its own restoring force, thereby driving the filter body 12 to automatically return to its original position and restore to its initial state.

[0079] It should be noted that the winding portion 126 can specifically adopt a winding device such as a spring spring, an elastic rope, etc. in the prior art. In one example, the winding portion 126 adopts a spring spring. In the first state, the spring spring can be wound around the support member 11 in the Z direction. One end of the spring spring is connected to the filter body 12. When the filter body 12 needs to be cleaned, the user holds the starting end 1201 of the filter body 12 and pulls it outward, so that the starting end 1201 of the filter body 12 moves away from the accommodating chamber 21 relative to the box body 2 under the action of external force, thereby driving the filter body 12 relative to the box body 2. As the support member 11 moves, the filter body 12 and the cleaning member 13 come into contact with each other. The friction between the filter body 12 and the cleaning member 13 removes dust accumulated on the filter body 12. During the movement of the filter body 12, the spring, connected to the filter body 12, is continuously stretched by force, switching from a first state to a second state. During this stretching process, the spring accumulates energy. After dust removal is complete, the spring automatically retracts under its own restoring force, thereby driving the filter body 12 to automatically return to its initial state. Of course, the reeling portion 126 can also achieve the above technical effects using an elastic cord, and its working principle will not be further described.

[0080] Furthermore, the first end of the reel 126 is connected to the end 1202 of the filter body 12, and the second end of the reel 126 is provided with a second bent portion 1261. In the second state, the second bent portion 1261 is in abutment with the support member 11. In the second state, the reel 126 is unfolded relative to the support member 11, and the first bent portion 125 is in abutment with the support member 11, thereby restricting the first bent portion 125 from further passing through the second through-slot of the support member 11, thereby acting as a limiter and preventing the reel 126 from separating from the support member 11 and being unable to return to the first state.

[0081] In one example, the end 1202 of the filter body 12 is disposed on a side of the first filter body 121 away from the second filter body 122 . In the second state, the first bent portion is snap-connected to a side of the first frame body 111 away from the second frame body 112 .

[0082] During the cleaning process of the filter body 12, the dust on the filter body 12 will fall off. In order to prevent the dust from contaminating the accommodating cavity 21 of the box body 2, the present application also provides a detachable dust box 14 to collect the dust falling on the filter body 12. The specific design is described as follows.

[0083] In some exemplary embodiments, Figure 3 and Figure 4As shown, the dust removal device 1 further includes a dust box 14, which is disposed below the support 11 and is used to collect dust accumulated on the filter body 12. The dust box 14 is detachably connected to the housing 2. When there is a lot of dust on the dust box 14, the user can remove the dust box 14 for cleaning to prevent dust from contaminating the housing 2.

[0084] Furthermore, the orthographic projection of the dust box 14 on the horizontal plane completely covers the orthographic projection of the support member 11 on the horizontal plane, so as to ensure that the dust accumulated on the filter body 12 can fall into the dust box 14, thereby preventing the dust from contaminating the box body 2 during the cleaning process.

[0085] In some exemplary embodiments, Figure 4 As shown, the support member 11 is partially hollowed out on the side facing the dust box 14. The dust box 14 is provided with an ash collection port 141 on the side facing the filter body 12. The ash collection port 141 is used to collect dust that falls during the cleaning process. The partial hollowing configuration specifically includes the following design: a first horizontal plate 1111 near the dust box 14 is provided with multiple through holes, and a second horizontal plate 1121 near the dust box 14 is provided with multiple through holes, and the multiple through holes can be arranged at intervals. During the cleaning process of the filter body 12, the filter body 12 moves relative to the support member 11, and dust in the first through slot on the support member 11 falls from the through holes through the ash collection port 141 into the dust box 14.

[0086] The through holes can be set to regular shapes such as circular, square, triangular, or irregular shapes, and are not specifically limited here. The size of the through holes and the spacing between two adjacent through holes cannot be too large, so as not to affect the normal sliding of the first filter body 121 and the second filter body 122. The above-mentioned partial hollowing design can prevent dust from accumulating on the support member 11, thereby ensuring the sliding stability of the filter body 12. At the same time, it can prevent dust from falling on the support member 11 and being sucked into the blocking space, causing dust accumulation in the condenser 3, thereby ensuring the heat exchange efficiency of the condenser 3 and improving the operating reliability of the refrigerator 100.

[0087] In some exemplary embodiments, Figure 8 and Figure 9 As shown, an extension rod 142 is provided on the side of the dust box 14 facing the user. The first end of the extension rod 142 is connected to the dust box 14, and the second end of the extension rod 142 extends away from the accommodating chamber 21. The end of the extension rod 142, which is away from the dust box 14, extends away from the accommodating chamber 21 and is exposed from the front of the refrigerator 100. After dust removal is completed, the user can stand in front of the refrigerator 100 and grasp the extension rod 142 to pull it out to remove the dust box 14 for cleaning. Therefore, whether cleaning the filter body 12 or the dust box 14, the user does not need to remove the refrigerator 100 from the cabinet, saving time and effort, and also eliminating the trouble of having to align the refrigerator 100 with the cabinet when resetting it.

[0088] The present application also provides a refrigerator 100, such as Figure 1 As shown, it includes a box body 2, a condenser 3 and a condensing fan 4 and the dust removal device 1 as described above, and the dust removal device 1 is arranged at the bottom of the refrigerator 100. The bottom of the box body 2 is provided with an accommodating cavity 21, and the condenser 3 and the condensing fan 4 are arranged in the accommodating cavity 21.

[0089] During the continuous refrigeration process of the refrigerator 100, since the support 11 is arranged around the circumference of the condenser 3 and the condensing fan 4, a barrier space is formed between the filter body 12 and the cabinet 2, which can prevent external dust from entering the barrier space, thereby avoiding dust accumulation on the condenser 3 and the condensing fan 4, while dust will gradually accumulate on the filter body 12. The starting end 1201 of the filter body 12 passes through the side of the housing 2 facing the user, that is, the starting end 1201 of the filter body 12 passes through the side of the housing 2 and is exposed on the front of the refrigerator 100. When the filter body 12 needs to be cleaned, the user can stand in front of the refrigerator 100 to operate. The user grasps the starting end 1201 of the filter body 12 and pulls it outward, so that the starting end 1201 of the filter body 12 moves away from the accommodating cavity 21 relative to the housing 2 under the action of an external force. During the movement of the filter body 12 relative to the support member 11, the filter body 12 continuously contacts the cleaning member 13. Due to the friction between the filter body 12 and the cleaning member 13, dust accumulated on the filter body 12 is removed by the cleaning member 13. Compared to the prior art, the user does not need to move the refrigerator 100 out of the cabinet, making the cleaning process simple and convenient. At the same time, the heat exchange efficiency of the condenser 3 is guaranteed, thereby improving the long-term operational reliability of the refrigerator 100.

[0090] The refrigerator 100 also includes a bottom plate 5 and a compressor 6 arranged on the bottom plate 5. The compressor 6 is connected to the condenser 3 through a refrigerant pipeline. The bottom plate 5 is connected to the cabinet 2. The space between the bottom plate 5 and the cabinet 2 constitutes a accommodating cavity 21 of the cabinet 2.

[0091] like Figure 4 As shown, the bottom plate 5 is further provided with an evaporation tray 7, and the condenser 3 and condensation fan 4 are both mounted on the evaporation tray 7. A dust box 14 can be disposed on the side of the evaporation tray 7 facing away from the evaporator. A support frame is disposed on the outer periphery of the evaporation tray 7 and is fixedly connected to the bottom plate 5. The dust box 14 can be mounted on the bottom plate 5 and located between the evaporation tray 7 and the bottom plate 5. A notch 51 is provided on the side of the bottom plate 5 facing the user for the dust box 14 to slide through, making it convenient for the user to remove the dust box 14 from the front of the refrigerator 100 for cleaning.

[0092] During the continuous refrigeration process of the refrigerator 100, dust gradually accumulates on the filter body 12, and may even block some of the heat dissipation holes 124, resulting in increased wind resistance of the filter body 12, thereby affecting the heat dissipation efficiency of the condenser 3 and causing the ambient temperature of the accommodating chamber 21 to rise. Therefore, the present application also provides a temperature detection device to detect the ambient temperature of the condenser 3 to prompt the user to remove dust. The specific design is described below.

[0093] In some exemplary embodiments, Figure 8 As shown, the refrigerator 100 includes a temperature detection device and a prompt device 8. The temperature detection device is configured to detect the ambient temperature Ts of the condenser 3. The prompt device 8 is electrically connected to the temperature detection device. The prompt device 8 is configured to prompt the user to remove dust when the ambient temperature Ts of the condenser 3 is higher than or equal to the preset temperature T0.

[0094] It should be noted that the temperature detection device includes a temperature sensor, which can be specifically arranged at a position close to the fins of the condenser 3. The position is specifically measured through experiments to determine the hot spots near the condenser 3, thereby accurately feeding back the ambient temperature Ts of the condenser 3. Of course, multiple temperature sensors can also be provided. By detecting the local temperatures T1 of multiple measuring points, the average temperature of multiple local temperatures is calculated to determine the ambient temperature Ts of the condenser 3.

[0095] It can be understood that the temperature detection device detects the ambient temperature of the condenser 3 in real time. If Ts≥T0, it indicates that the filter body 12 is seriously dusty at this time, prompting the user to remove dust in time to avoid the condenser 3 from operating at an excessively high ambient temperature, thereby ensuring the heat dissipation effect of the condenser 3 and improving the long-term operation reliability of the system.

[0096] In one example, if Figure 8 As shown, the prompting device 8 includes a display panel mounted on the front of the refrigerator 100. If Ts ≥ T0, the display panel issues an alarm prompting the user to remove dust. After dust removal, if Ts < T0, the alarm is released. If, after a period of time after dust removal from the filter body 12, the ambient temperature Ts surrounding the condenser 3 still does not fall below the preset temperature, the display panel continues to issue an alarm prompt. Upon receiving the alarm, the user promptly contacts the company's after-sales service, who will conduct a site inspection and promptly eliminate the cause of the abnormality.

[0097] In some exemplary embodiments, Figure 10As shown, refrigerator 100 includes a rear cover 9 that covers the accommodating cavity 21 of housing 2. Rear cover 9 is provided with an air inlet 91 and an air outlet 92 that communicate with accommodating cavity 21. Condensing fan 4 utilizes forced convection heat exchange to create a bidirectional heat dissipation cycle, with external air flowing in through air inlet 91 and high-temperature internal air being discharged through air outlet 92. This achieves excellent heat dissipation, thereby ensuring the long-term operational reliability of the system.

[0098] Furthermore, the air inlet 91 is correspondingly connected to the heat dissipation holes 124 of the second filter body 122, and the condensing fan 4 forces convection heat exchange, so that the external air enters the blocking space from the air inlet 91 through the heat dissipation holes 124 of the second filter body 122, and the high-temperature hot air is then discharged from the air outlet 92 through the heat dissipation holes 124 of the first filter body 121. The dust in the external air is blocked by the filter body 12, thereby avoiding dust accumulation on the condenser 3 and the condensing fan 4, and ensuring the heat exchange performance of the condenser 3.
