Description

Technical Field

Household appliances such as refrigerators have become one of the indispensable household appliances in the family. Among them, in order to integrate the refrigerator with the cabinet, the distance between the refrigerator and the cabinet is relatively small. In order to increase the volume ratio of the refrigerator, the back of the refrigerator is close to the cabinet. The back and both sides of the refrigerator cannot dissipate heat, and the bottom heat dissipation method can only be adopted. However, after the bottom heat dissipation structure has been running for a long time, dust in the air will accumulate on the condenser fins. If it is not cleaned for a long time, it will cause dirt and blockage, resulting in a decrease in the heat exchange efficiency of the condenser. In severe cases, it will cause system shutdown and excessive compressor temperature and other undesirable phenomena.

[0003] In the related art, the traditional method of dust removal for condensers is to completely disassemble the condenser for cleaning. The disassembly and cleaning process is cumbersome, so the user's maintenance cycle for the condenser is long, which makes the condenser not in the best working condition for a long time, resulting in reduced heat exchange efficiency of the condenser. Especially for built-in refrigerators, users need to move the refrigerator out of the cabinet, and it is difficult to align the refrigerator with the cabinet when resetting it.

[0056] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0057] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0058] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are 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 both sides of the refrigerator 200 cannot dissipate heat, and can only use the bottom heat dissipation method. The built-in refrigerator 200 uses an external condenser 203 instead of the built-in condenser 203. The external condenser 203 can reduce the load of the box. The compressor compartment 201 at the bottom of the refrigerator 200 is separated into two chambers with the condensing fan 202 as the boundary. The condensing fan 202 is used to force convection heat exchange to form a two-way circulation heat dissipation system with left air outlet at the bottom and right air intake at the rear. There is no need to reserve heat dissipation space on both sides and the top, so as to achieve a 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 cause dirt and blockage, resulting in a decrease in the heat exchange efficiency of the condenser 203. In severe cases, it will cause system shutdown and excessive temperature of the compressor 204. In the related art, the conventional dust removal method of the condenser 203 is to completely disassemble the condenser 203 for cleaning. The disassembly and cleaning process is troublesome, so the user has a long maintenance period for the condenser 203, which makes the condenser 203 not in the best working state for a long time, resulting in reduced heat exchange efficiency of the condenser 203. In particular, for a built-in refrigerator 200, the user needs to move the refrigerator 200 out of the cabinet before disassembling and cleaning the condenser 203, which is time-consuming and laborious. When resetting, it is difficult for the refrigerator 200 to be centered with the cabinet.

[0060] In order to solve the technical problem that the condenser of the existing refrigerator is difficult to clean, 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 A dust removal device 1 provided in the present application 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. A receiving cavity 21 is provided at the bottom of the box body 2. The condenser 3 and the condensing fan 4 are arranged in the receiving 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 shape around the circumference of the condenser 3 and the condensing fan 4, or can be arranged in an L shape around the adjacent two 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 202, 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 beginning 1201 of the filter body 12 is extended from the side of the housing 2 toward the user, that is, the beginning 1201 of the filter body 12 is exposed on the front of the refrigerator 100 after passing through the side of the housing 2. When the filter body 12 needs to be cleaned, the user can stand on the front of the refrigerator 100 to operate. The user holds the beginning 1201 of the filter body 12 and pulls it outward, so that the beginning 1201 of the filter body 12 moves away from the accommodating cavity 21 relative to the housing 2 under the action of external force. The filter body 12 continues to contact the cleaning member 13 during the movement relative to the support member 11. Under 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. Compared with the prior art, when dust removal is required, the user does not need to move the refrigerator 100 out of the cabinet. The cleaning process is simple and convenient, saving time and effort. At the same time, it can avoid dust accumulation on the fins of the condenser 3, ensure the heat exchange efficiency of the condenser 3, and thus improve the long-term operation reliability of the refrigerator 100.

[0064] In addition, if Figure 4As shown, the filter body 12 can be an integral part made of a flexible material, so that the filter body 12 itself has a certain degree of flexibility. When the support member 11 is arranged in a ring around the condenser 3 and the condensation fan 4, the filter body 12 can be bent into a ring relative to the support member 11; when it can be arranged in a square around the condenser 3 and the condensation 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 condensation 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, the first frame body 111 and the second frame body 112 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, and 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] Optionally, the first horizontal direction may be the X direction shown in the figure. It is understandable that, in the initial state of the filter body 12, that is, when the beginning 1201 of the filter body 12 is not subjected to external force, the first filter body 121 is connected to the first frame 111, and the second filter body 122 is connected to the second frame 112. Since the first frame 111 is arranged on the side of the condensing fan 4 away from the condenser 3, that is, the first frame 111 is arranged around the outer peripheral side of the condensing fan 4, the first filter body 121 on the first frame 111 separates the condensing fan 4 from the compressor 6, and the second frame 112 is arranged on the side of the condenser 3 away from the user, that is, the second frame 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 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 , and the first filter body 121 , the second filter body 122 and the box body 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 performance of the condenser 3 .

[0067] Further, 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, thereby blocking 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 away from the accommodating chamber 21 relative to the box body 2 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 drives 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 are in contact with the cleaning room, and 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 body 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 body 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 body 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 body 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 a second slide groove 114 for the filter body 12 to slide through, and the second slide groove 114 is provided in the vertical direction. Specifically, the side wall of the first vertical plate is provided with the second slide groove 114 in the vertical direction, and the side wall of the second vertical plate is provided with the second slide groove 114 in the vertical 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 moves along the Y direction on the first slide groove 113 of the second frame 112 and passes through the second slide groove 114 of the second frame 112, and the first filter body 121 moves along the X direction on the first slide groove 113 of the first frame 111 and passes through the second slide groove 114 of the first frame 111 and the second slide groove 114 of the second frame 112 in sequence. By providing the second slide groove 114 , the stability of the movement of the filter body 12 can be improved, so that it is convenient to remove the dust accumulated on the filter body 12 in the cleaning room.

[0073] In some exemplary embodiments, Figure 5As shown, the cleaning member 13 includes a brush 131, which is arranged on the second chute 114 and abuts against the filter body 12. When the second filter body 122 passes through the second chute 114, the brush 131 brushes away the dust accumulated on the second filter body 122 due to the friction between the second filter body 122 and the brush 131; when the first filter body 121 passes through the second chute 114, the brush 131 brushes away the dust accumulated on the first filter body 121 due to the friction between the first filter body 121 and the brush 131, thereby cleaning the filter body 12. The cleaning process saves time and effort, and is convenient for users to operate.

[0074] Alternatively, if Figure 5 As shown, the second frame 112 includes a reinforcing plate 1123, both ends of the reinforcing plate 1123 are respectively connected to the second transverse plate 1121, and a second slide groove 114 is provided on the reinforcing plate 1123. A brush 131 is provided in the second slide groove 114 of the reinforcing plate 1123. By providing the reinforcing plate 1123, the structural strength of the second frame 112 can be improved, thereby improving the smoothness of the movement of the filter body 12 relative to the second frame 112, and at the same time, the brush 131 on the reinforcing plate 1123 can be used to clean the dust on the filter body 12, further improving the cleaning strength.

[0075] In some exemplary embodiments, Figure 6 and Figure 7 As shown, the filter body 12 also includes a third filter body 123, the first filter body 121, the second filter body 122 and the third filter body 123 are sequentially connected; the box body 2 has a foam layer 22, and the foam layer 22 located on the side of the box body 2 is provided with a through groove 23, and the third filter body 123 is slidably connected with the through groove 23. During installation, the beginning 1201 of the filter body 12 passes through the second slide groove 114 of the first frame and the second slide groove 114 of the second frame in sequence, and then passes through the through groove 23 set on the foam layer 22 on the side of the box body 2, and then is exposed to the front of the refrigerator 100, saving installation space. Since the third filter body 123 is set inside the foam layer of the box body 2, dust accumulation on the third filter body 123 can also be avoided, and the dust accumulation area of ​​the filter body 12 is reduced, thereby saving the user's cleaning time.

[0076] Furthermore, if Figure 6 and Figure 7 As shown, the beginning 1201 of the filter body 12 is arranged at a side of the third filter body 123 away from the second filter body 122, and the beginning 1201 of the filter body 12 is provided with a first bent portion 125, which is in contact with the side of the box body 2 facing the user. In the initial state, the first bent portion 125 is in contact with the side of the box body 2 facing the user, which plays a positioning role. When the filter body 12 needs to be cleaned, the user holds the first bent portion 125 and pulls it outward, which is convenient 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 array-distributed heat dissipation holes 124. The heat dissipation holes 124 can be set to a circular, square, diamond, honeycomb, etc. shape, which is not specifically limited here. The array distribution of the heat dissipation holes 124 specifically includes that the heat dissipation holes 124 are distributed in a ring array on the first filter body 121 and the second filter body 122; or, the heat dissipation holes 124 are distributed in a rectangular array on the first filter body 121 and the second filter body 122, which is not specifically limited in this application. The heat generated by the condenser 3 can be dissipated to the outside of the box body 2 through the heat dissipation holes 124 to ensure the heat dissipation effect of the condenser 3, thereby improving the long-term operation reliability of the condenser 3. The size of the heat dissipation holes 124 is designed according to actual needs. While ensuring the heat dissipation effect of the condenser 3, it can prevent external dust from entering the isolation space and avoid dust accumulation in the condenser 3 and the condensing fan. It should be noted that since the third filter body 123 is arranged in the foaming layer of the box body 2, there is no need to set additional heat dissipation holes 124.

[0078] In some exemplary embodiments, Figure 6 As shown, the end 1202 of the filter body 12 is provided with a reel 126, and the reel 126 is provided on the side of the support 11 close to the condensing fan 4; the reel 126 has a first state of being reeled relative to the support 11 and a second state of being unfolded relative to the support 11. In the second state, the reel 126 drives the filter body 12 to automatically return to its original position under the action of its own restoring force. When the filter body 12 needs to be cleaned, the user holds the beginning 1201 of the filter body 12 and pulls it outward, so that the beginning 1201 of the filter body 12 moves away from the accommodating chamber 21 relative to the box 2 under the action of external force, thereby driving the filter body 12 to move relative to the support 11, and the filter body 12 and the cleaning member 13 are in 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 is continuously extended, 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 winds up 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 an external force, thereby driving the filter body 12 relative to the box body 2. The support member 11 moves, and the filter body 12 and the cleaning member 13 come into contact with each other. Under 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, since the spring spring is connected to the filter body 12, the spring spring is continuously stretched by force, switching from the first state to the second state. The spring spring stores energy during the stretching process. After the dust removal is completed, the spring spring automatically rewinds under the action of its own restoring force, thereby driving the filter body 12 to automatically return to its original position and return to its initial state. Of course, the reeling part 126 can also achieve the above technical effect by using an elastic rope, and its working principle will not be repeated.

[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 abutted and connected 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 abutted and connected with the support member 11, thereby limiting the first bent portion 125 from continuing to pass through the second through slot of the support member 11, playing a limiting role, and preventing the reel 126 from detaching 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 , and in the second state, the first bending portion is snap-connected with 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, since 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 from 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 the 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 housing 2 during the cleaning process.

[0085] In some exemplary embodiments, Figure 4 As shown, the support member 11 is partially hollowed out on one side facing the dust box 14, and the dust box 14 is provided with an ash collecting port 141 on one side facing the filter body 12. The ash collecting port 141 is used to receive dust dropped during the cleaning process. The partial hollowing out specifically includes the following designs: a first transverse plate 1111 close to the dust box 14 is provided with a plurality of through holes, and a second transverse plate 1121 close to the dust box 14 is provided with a plurality of through holes, and the plurality of 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 the dust in the first through groove on the support member 11 falls into the dust box 14 from the through hole through the ash collecting port 141.

[0086] The through hole can be set to a regular shape such as a circle, a square, a triangle, or an irregular shape, and no specific limitation is made here. The size of the through hole 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 hollow design can prevent dust from accumulating on the support 11, thereby ensuring the sliding stability of the filter body 12, and at the same time, it can prevent dust from falling on the support 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 Fig. 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 in a direction away from the accommodating chamber 21. The end of the extension rod 142 away from the dust box 14 extends in a direction away from the accommodating chamber 21 and is exposed from the front of the refrigerator 100. After dust removal is completed, the user stands in front of the refrigerator 100 and can hold the extension rod 142 and pull it outward to take out the dust box 14 for cleaning. Therefore, whether it is the cleaning process of the filter body 12 or the cleaning process of the dust box 14, the user does not need to move the refrigerator 100 out of the cabinet, which saves time and effort, and also saves the trouble of difficulty in aligning the refrigerator 100 with the cabinet when resetting it again.

[0088] The present application also provides a refrigerator 100, such as Figure 1 As shown, the refrigerator 100 includes a housing 2, a condenser 3, 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 housing 2 is provided with a receiving cavity 21, and the condenser 3 and the condensing fan 4 are arranged in the receiving 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 preventing dust from accumulating on the condenser 3 and the condensing fan 4, while dust will gradually accumulate on the filter body 12. The beginning 1201 of the filter body 12 passes through the side of the housing 2 facing the user, that is, the beginning 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 holds the beginning 1201 of the filter body 12 and pulls it outward, so that the beginning 1201 of the filter body 12 moves away from the accommodating cavity 21 relative to the housing 2 under the action of external force. During the movement of the filter body 12 relative to the support member 11, the filter body 12 continues to contact the cleaning member 13. Under the friction between the filter body 12 and the cleaning member 13, the dust on the filter body 12 is removed by the cleaning member 13. Compared with the prior art, the user does not need to move the refrigerator 100 out of the cabinet, the cleaning process is simple and convenient, and the heat exchange efficiency of the condenser 3 can be guaranteed, thereby improving the long-term operation reliability of the refrigerator 100.

[0090] The refrigerator 100 also includes a bottom plate 5 and a compressor 6 disposed on the bottom plate 5 . The compressor 6 is connected to the condenser 3 via 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 receiving cavity 21 of the cabinet 2 .

[0091] like Figure 4 As shown, an evaporation tray 7 is also provided on the bottom plate 5, the condenser 3 and the condensation fan 4 are both installed on the evaporation tray 7, the dust box 14 can be provided on the side of the evaporation tray 7 away from the evaporator, the support frame is provided on the outer peripheral side of the evaporation tray 7 and is fixedly connected to the bottom plate 5, the dust box 14 can be installed on the bottom plate 5, and the dust box 14 is 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, so that the dust box 14 can slide through, so that the user can 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 will gradually accumulate on the filter body 12, and even block part of the heat dissipation holes 124, resulting in a larger 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 cavity 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, and the specific design is described as follows.

[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, and 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, and the temperature detection device 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 heat point near the condenser 3, so as to accurately feedback the ambient temperature Ts of the condenser 3; of course, multiple temperature sensors can also be arranged, by detecting the local temperature T1 of multiple measuring points, and thus calculating the average temperature of multiple local temperatures, so as 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 running 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 arranged on the front of the refrigerator 100. If Ts≥T0, an alarm prompt can be issued on the display panel to remind the user to remove dust. After dust removal, if Ts<T0, the alarm prompt is released. After a period of time after the filter body 12 is dusted, if the ambient temperature Ts of the condenser 3 is still not lower than the preset temperature, the display panel continues to issue an alarm prompt. After the alarm, the user promptly contacts the company's after-sales service, and the after-sales staff conducts on-site inspections to promptly eliminate the abnormal cause.

[0097] In some exemplary embodiments, Fig.10As shown, the refrigerator 100 includes a rear cover 9, which covers the accommodating cavity 21 of the box body 2, and is provided with an air inlet 91 and an air outlet 92 which are connected to the accommodating cavity 21. The condensing fan 4 is used to force convection heat exchange, forming a two-way circulation heat dissipation process in which external air flows in from the air inlet 91 and internal high-temperature air is discharged from the air outlet 92, thereby achieving a good heat dissipation effect, thereby ensuring the long-term operation 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, thereby ensuring the heat exchange performance of the condenser 3.
