[0046] An air inlet is provided on the back of the refrigerator 11, and an air outlet is provided on the front of the refrigerator 11. The air outlet is positioned opposite to the air inlet to form an air duct. A dustproof net 12 is provided at the air inlet to prevent external dust from entering.

The linear module 211 is an existing structure, so it will not be described again. In this embodiment, the linear module 211 drives the installation box 221 to move back and forth upward or downward along the height direction Z of the refrigerator, and improves the stability of the movement of the installation box 221 under the action of the limiting slide 212.

Some solutions need to add water for cleaning, and the sewage pollutes the environment around the refrigeration equipment. Compared with the existing cleaning roller solution, the dust is directly attached to the adhesive tape 2221 during the cleaning process of the dustproof net, and the dust is not swept into the interior of the refrigeration equipment, and the environment around the refrigeration equipment is not polluted.

[0052] As Figure 6As shown, the dust removal mechanism 2 further comprises a first camera 3, the first camera 3 is installed at the bottom of the mounting box 221, the first camera 3 is aligned with the dust screen 12, the first camera 3 is used to detect the dust coverage rate on the dust screen 12, and the first camera 3 is in communication connection with the control mechanism; when the first camera 3 detects that the dust coverage rate on the dust screen 12 exceeds a first preset coverage rate, the control mechanism controls the movement assembly 21 to operate, and the adhesive roller 222 moves downward to the bottom along the height direction Z of the refrigerator, at the same time, the adhesive tape 2221 is unfolded and adheres to the dust on the dust screen 12; when the adhesive roller 222 moves upward along the height direction Z of the refrigerator, the winding motor 233 drives the winding roller 232 to wind synchronously, the first camera 3 detects the dust coverage rate on the dust screen 12, and if the first camera 3 detects that the dust coverage rate on the dust screen 12 still exceeds the first preset coverage rate, the control mechanism controls the movement assembly 21 to continue to operate until the dust coverage rate on the dust screen 12 is lower than the first preset coverage rate.

[0053] In the embodiment, the camera is installed at the bottom of the mounting box 221 away from one end of the dust screen 12, so that the camera has a larger wide angle and can shoot a larger range of the dust screen 12, thereby better detecting the dust coverage rate on the dust screen 12.

[0054] In actual use, the first preset coverage rate can be set to 70% coverage rate. Initially, when the first camera 3 detects that the dust coverage rate is 75%, the control mechanism controls the movement assembly 21 to operate, and the adhesive roller 222 moves downward to the bottom along the height direction Z of the refrigerator, at the same time, the adhesive tape 2221 is unfolded and adheres to the dust on the dust screen 12. Then, the adhesive roller 222 moves upward along the height direction Z of the refrigerator under the action of the movement assembly 21, in this process, the winding roller 232 winds synchronously, and at the same time, the first camera 3 continues to detect, and when the first camera 3 detects that the dust coverage rate on the dust screen 12 after the first cleaning still exceeds 70% coverage rate, the control mechanism continues to control the movement assembly 21 to operate until the dust coverage rate on the dust screen 12 is lower than 70% coverage rate.

[0055] In this way, by setting the first camera 3, the number of times of cleaning of the adhesive roller 222 can be accurately determined according to the dust coverage rate on the dust screen 12, and waste of the adhesive tape 2221 caused by excessive cleaning is avoided.

[0056] As shown in the figure, Figure 5 The adhesive assembly 22 further comprises an adhesive motor 223 and a shaft coupling 224, both of which are installed in the mounting box 221, the output end of the adhesive motor 223 is connected with the adhesive roller 222 through the shaft coupling 224, and the adhesive motor 223 drives the adhesive roller 222 to rotate.

[0057] The gluing motor can rotate forward (counterclockwise) or reverse (clockwise). When the gluing motor rotates forward, it assists in unrolling the adhesive tape 2221. When the gluing motor 223 rotates reversely, it rewinds the unrolled adhesive tape 2221 onto the gluing roller 222. The forward and reverse speeds of the gluing motor 223 can be set according to actual conditions. In particular, the reverse speed of the gluing motor 223 can be consistent with the moving speed of the moving assembly 21.

[0058] In this way, the glue motor 223 is connected to the glue roller 222 through the coupling 224, which ensures that the glue roller 222 can idle while the tape 2221 on the glue roller 222 is unfolded under the traction of the moving component 21; it can also rotate under the action of the glue motor 223 to assist in unfolding the tape 2221 or rewinding the unfolded tape 2221.

[0059] like Figure 4 and Figure 6 As shown, the dust removal mechanism 2 also includes a second camera 4, which is installed in the refrigerator 11. A detection hole 121 is opened in the middle of the dustproof net 12, and the second camera 4 is aligned with the detection hole 121. The second camera 4 is used to detect the dust coverage rate on the unfolded adhesive tape 2221, and the second camera 4 is communicated with the control mechanism; when the second camera 4 detects that the dust coverage rate on the unfolded adhesive tape 2221 does not exceed the second preset coverage rate, the control mechanism controls the glue motor 223 to run, and the glue roller 222 reels the unfolded adhesive tape 2221 that has dropped to the bottom; when the second camera 4 detects that the dust coverage rate on the unfolded adhesive tape 2221 exceeds the second preset coverage rate, the control mechanism controls the reeling component 23 to reel in the unfolded adhesive tape 2221 that has dropped to the bottom.

[0060] The second camera 4 can be mounted within the refrigerator 11 using a camera mounting bracket. While not affecting the cleaning of dust from the dust screen 12 by the adhesive tape 2221, the second camera 4 can capture the unfolded adhesive tape 2221 through the detection hole 121. Optionally, the detection hole 121 can be larger than the mesh hole on the dust screen 12, thereby enabling the second camera 4 to obtain a wider angle and capture a wider range of the unfolded adhesive tape 2221.

[0061] Optionally, the second camera 4 can be used in cooperation with the first camera 3, the first camera 3 detects the dust coverage on the dust screen 12, and the second camera 4 detects the dust coverage on the expanded adhesive tape 2221, which do not affect each other and have different detection timing. The detection timing of the first camera 3 is when the cleaning operation just starts and when the adhesive tape 2221 on the adhesive roller 222 is fully coated with adhesive and moves upward. The detection timing of the second camera 4 is when the adhesive tape 2221 is half expanded, the dust coverage on the adhesive tape 2221 is detected, or when the adhesive tape 2221 is fully expanded, the dust coverage on the adhesive tape 2221 is detected, or when the adhesive tape 2221 is gradually expanded as the adhesive roller 222 moves downward, the dust coverage on the adhesive tape 2221 is detected in real time.

[0062] In actual use, the second preset coverage can be set to 60%. When the second camera 4 detects that the dust coverage on the expanded adhesive tape 2221 is 50%, the control mechanism controls the adhesive motor 223 to operate, and the adhesive roller 222 winds the expanded adhesive tape 2221 that has been lowered to the bottom, until the second camera 4 detects that the dust coverage on the expanded adhesive tape 2221 exceeds 60%, at which time the control mechanism controls the winding assembly 23 to wind the expanded adhesive tape 2221 that has been lowered to the bottom.

[0063] In this way, by setting the second camera 4 to detect the dust coverage on the expanded adhesive tape 2221, the adhesive tape 2221 that is not fully used can be reused, thereby reducing the consumption of adhesive tape 2221 and saving costs.

[0064] As shown in Figures 7 to 10 The dust removal mechanism 2 also includes an adjusting assembly 24, the adjusting assembly 24 includes two limiting rails 241, two sliding seats 242, and two elastic members 243, the two limiting rails 241 extend along the width direction Y of the refrigeration machine and are respectively installed on the inner walls of the two sides of the mounting box 221, each limiting rail 241 corresponds to a sliding seat 242 and an elastic member 243, the sliding seat 242 slides in the limiting rail 241, and the elastic member 243 is installed between the sliding seat 242 and the limiting rail 241, and the two sliding seats 242 are clamped with the adhesive roller 222; wherein the adjusting assembly 24 adjusts the position of the adhesive roller 222 along the width direction Y of the refrigeration machine, so that the adhesive tape 2221 is always tightly attached to the outside of the dust screen 12.

[0065] The elastic member 243 has elasticity and can elastically contract when subjected to pressure, and can recover to the original shape when the pressure disappears. The elastic member 243 can be made of metal spring or other metal elastic material, or can be made of rubber, silicone or other non-metallic elastic material.

[0066] In this embodiment, the limiting rail 241 is arranged in a U shape, and the sliding seat 242 slides in the U shape. Optionally, the sliding seat 242 comprises a hollow sliding block 2421 and a support seat 2422, the hollow sliding block 2421 slides in the limiting rail 241, the support seat 2422 is fixed on one side of the hollow sliding block 2421, the top end of the support seat 2422 is provided with a U-shaped socket 2423, the roller heads on both sides of the adhesive roller 222 are clamped into the corresponding U-shaped sockets 2423, and an elastic element 243 is arranged between the hollow sliding block 2421 and the inner wall of one end of the limiting rail 241. The hollow sliding block 2421 is also arranged in a U shape, and the two U-shaped structures are complementary, so that the stability of the sliding of the sliding seat 242 can be ensured. In some embodiments, as shown in Figure 10 The elastic element 243 is arranged at two positions in the height direction Z of the refrigerator, and the length of each elastic element 243 is between the maximum compression length and half the original length.

[0067] In this way, the elastic element 243 is always in a compressed state, and under the elastic force of the elastic element 243, the sliding seat 242 drives the adhesive roller 222 to move, so that the adhesive roller 222 can always be close to the outer side of the dust screen 12. Therefore, when the moving assembly 21 moves in the height direction Z of the refrigerator, the adhesive roller 222 rolls under the friction force, so that the adhesive tape 2221 adheres the dust on the dust screen 12, thereby achieving cleaning of the dust screen 12.

[0068] As shown in Figures 11 to 13 The mounting box 221 comprises a semi-enclosed box 2211, a protective cover 2212 and two blocking blocks 2213, the protective cover 2212 is detachably installed on the top of the semi-enclosed box 2211, the blocking blocks 2213 are respectively arranged on the two sides of the bottom of the protective cover 2212, the blocking blocks 2213 correspond to the openings of the sliding seat 242, and the blocking blocks 2213 are used for abutting against the adhesive roller 222 to prevent the adhesive roller 222 from falling off the sliding seat 242.

[0069] One side of the semi-enclosed box 2211 is open, and the top of the semi-enclosed box 2211 is detachably connected with the protective cover 2212 through fasteners. Optionally, the semi-enclosed box 2211 and the protective cover 2212 can be made of transparent material, so as to facilitate observation of the use of the adhesive tape 2221 on the adhesive roller 222.

[0070] When the adhesive roller 222 is installed, the roller head of the adhesive roller 222 is directly aligned with the opening (which can be a U-shaped socket 2423) of the sliding seat 242, which facilitates the arrangement of the adhesive roller 222 in the sliding seat 242, and then the opening position of the sliding seat 242 is blocked by the blocking blocks 2213 to prevent the adhesive roller 222 from falling out of the sliding seat 242.

[0071] In this embodiment, as shown in Figure 12 and Figure 13As shown, the first outer protrusion 2214 is fixed on both sides of the semi-closed box 2211, and the second outer protrusion 2216 is fixed on both sides of the protective cover 2212. The first outer protrusion 2214 and the second outer protrusion 2216 are the same in structure and are arranged in an upper-lower stacking manner. The first outer protrusion 2214 and the second outer protrusion 2216 are connected through a bolt assembly 25. The bolt assembly 25 is similar to a hand screw structure. By controlling the position of the bolt assembly 25, the combination or separation state of the semi-closed box 2211 and the protective cover 2212 can be switched. When the semi-closed box 2211 and the protective cover 2212 are combined, the adhesive roller 222 can be prevented from falling out of the semi-closed box 2211. When the semi-closed box 2211 and the protective cover 2212 are separated, the installation or replacement of the adhesive roller 222 can be completed.

[0072] Specifically, a first threaded hole 2215 is formed at the top end of the first outer protrusion 2214, a hole groove 2217 is formed at the bottom end of the second outer protrusion 2216, and a second threaded hole 2218 is formed at the top end of the second outer protrusion 2216 and communicates with the hole groove 2217. The inner diameter of the hole groove 2217 is greater than the hole diameter of the first threaded hole 2215, the hole diameter of the first threaded hole 2215 is greater than the hole diameter of the second threaded hole 2218, and the height of the hole groove 2217 along the height direction Z of the refrigerator is greater than the height of the first threaded hole 2215 along the height direction Z of the refrigerator.

[0073] The bolt assembly 25 includes a first screw rod 251, a second screw rod 252, and an end head 253 from bottom to top along the height direction Z of the refrigerator. The first screw rod 251 is threadedly connected with the first threaded hole 2215, the second screw rod 252 is threadedly connected with the second threaded hole 2218, and the periphery of the end head 253 is provided with threads for easy rotation. The first screw rod 251, the second screw rod 252, and the end head 253 are integrally cast. In actual use, the end head 253 is counterclockwise rotated to make the first screw rod 251 completely located in the hole groove 2217, so that the semi-closed box 2211 and the protective cover 2212 can be separated, and the bolt assembly 25 will not fall off the protective cover 2212, avoiding the loss of the bolt assembly 25. The end head 253 is clockwise rotated to make the first screw rod 251 screwed into the first threaded hole 2215, so that the semi-closed box 2211 and the protective cover 2212 can be closed, and the convenience of the protective cover 2212 in use can be improved.

[0074] In this way, the top of the semi-closed box 2211 is detachably provided with the protective cover 2212, so that the adhesive roller 222 can be conveniently replaced. In addition, the blocking block 2213 can prevent the adhesive roller 222 from falling off the sliding seat 242 and fix the position of the adhesive roller 222 in the height direction Z of the refrigerator.

[0075] As Figure 6As shown, the dust removal mechanism 2 further comprises a thickness detection sensor 5, which is installed on the inner wall of the mounting box 221, and the detection end of the thickness detection sensor 5 is aligned with the side surface of the adhesive roller 222. The thickness detection sensor 5 is used to detect the thickness of the adhesive roller 222. If the thickness detection sensor 5 detects that the thickness of the adhesive roller 222 is lower than the preset thickness, the adhesive tape 2221 on the adhesive roller 222 is used up, and the adhesive tape 2221 needs to be replaced.

[0076] The thickness detection sensor 5 can be a laser triangulation sensor or a third camera. The preset thickness can be 40 mm. In some embodiments, the dust removal mechanism 2 further comprises an alarm, which is in communication connection with the control mechanism. The worker can be prompted by the alarm.

[0077] In this way, the thickness of the adhesive tape 2221 can be detected in real time by the thickness detection sensor 5, and an alarm is given when the thickness of the adhesive roller 222 is lower than the preset thickness, so that the replacement is prompted, and the cleaning is not interrupted.

[0078] As shown in Figure 9 The bottom of the mounting box 221 is provided with a gap 2219 near one end of the adhesive roller 222.

[0079] Optionally, the width of the gap 2219 along the width direction Y of the refrigerator is less than half of the width of the mounting box 221 along the width direction Y of the refrigerator.

[0080] In this way, the dust can pass through the gap 2219, and then the passing dust is adhered and adsorbed by the adhesive tape 2221 on the adhesive roller 222.

[0081] As shown in Figure 6 The winding assembly 23 further comprises a protective cover 234, which covers the winding roller 232.

[0082] The protective cover 234 is convenient to open or cover, so that the wound adhesive tape 2221 on the winding roller 232 is taken out or the new adhesive tape 2221 is re-pasted. Optionally, the protective cover 234 can be transparent, which is convenient to observe the winding adhesive tape 2221 on the winding roller 232.

[0083] In this way, the protective cover 234 is arranged to protect the winding roller 232, so that the winding roller 232 is not affected by the external environment (such as rain), and the function of the winding assembly 23 is not affected.

[0084] According to some embodiments of the present application, the present embodiment also relates to a machine room refrigeration method, comprising the machine room refrigeration device 100, and further comprising the following steps: S1: the linear module 211 drives the installation box 221 to move downward along the height direction Z of the refrigerator, the head end of the adhesive tape 2221 is fixed, and the adhesive tape 2221 on the adhesive roller 222 is unrolled and adheres to the dust on the dust screen 12 during the downward movement of the installation box 221; S2: when the installation box 221 moves downward to the bottom, the unrolled adhesive tape 2221 covers the entire dust screen 12, the control mechanism controls the linear module 211 to drive the installation box 221 to move upward along the height direction Z of the refrigerator, and at the same time, the control winding motor 233 is controlled to operate synchronously, and the winding roller 232 winds the unrolled adhesive tape 2221. S3: repeat steps S1 to S2 until the dust on the dust screen 12 is adhered.

[0085] In step S2, it needs to be pointed out that: the winding speed of the winding motor 233 matches the moving speed of the linear module 211, so as to prevent the adhesive tape 2221 from loosening or tearing. In some embodiments, the winding speed of the winding motor 233 can also be slower than the moving speed of the linear module 211.

[0086] The technical solution of the present application unrolls the adhesive tape 2221 on the adhesive roller 222 and adheres to the dust on the dust screen 12 during the downward movement of the installation box 221, thereby effectively cleaning the dust on the dust screen 12. In addition, the winding roller 232 can wind the used adhesive tape 2221, automatically wind and update the adhesive tape 2221, and realize automatic cleaning under the action of the control mechanism.

[0087] It should be noted that although the above embodiments have been described in the present text, the patent protection scope of the present application is not limited thereby. Therefore, based on the innovative idea of the present application, changes and modifications to the embodiments described in the present text, or equivalent structures or equivalent process transformations made by using the contents of the present application specification and drawings, directly or indirectly apply the above technical solutions to other related technical fields, are all included in the patent protection scope of the present application.
