DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0021] Embodiment 1: See also Figure 1 - Figure 6 An energy-saving refrigeration device includes a refrigerator body 1 and a protection box 2 located outside the refrigerator body 1. The protection box 2 protects the entire refrigerator body 1, and the top of the protection box 2 is a sloping roof structure to avoid the accumulation of rain and snow.

[0022] The middle part of the side of the refrigerator body 1 can be connected to a hose through a flange, and the hose is connected to the outside of the protection box 2. In this way, when the height of the refrigerator body 1 changes, it will not affect the liquid in and out of the refrigerator body 1.

[0023] Oblique exhaust vents 3 are provided on both sides of the protection box 2, and dustproof nets 301 are fixedly installed on the oblique exhaust vents 3. The oblique exhaust vents 3 can be used to discharge hot air to the outside, and the obliquely arranged structure is not easy to cause rain and snow to enter the interior of the protection box 2, thereby avoiding direct contact between rain and snow and the refrigerator body 1. At the same time, the dustproof net 301 can also effectively block dust.

[0024] A cleaning scraper 4 is provided at each oblique air outlet 3, and a cleaning control component 5 is provided inside the protective box 2. The cleaning control component 5 controls the cleaning scraper 4 to move up and down. When the scraper moves up and down, the dust accumulated on the dustproof net 301 will be effectively scraped off to prevent dust accumulation, thereby avoiding the problem of reduced heat dissipation effect due to dust accumulation.

[0025] A suspension assembly 6 is provided inside the protection box 2 , and the suspension assembly 6 controls the height change of the refrigerator body 1 . When it is rainy or snowy, the suspension assembly 6 is used to increase the height of the refrigerator body 1 to prevent moisture from penetrating into the refrigerator body 1 .

[0026] The cleaning control component 5 includes a main control motor 501, which is fixed inside the protective box 2, and the output end of the main control motor 501 is connected to a long rotating shaft 502 through a coupling transmission. A plurality of first gears 503 are fixedly installed on the side of the long rotating shaft 502, and each first gear 503 is meshed with a second gear 504. The first gears 503 and the second gears 504 are vertically distributed and form a bevel gear structure. The second gear 504 is connected to a third gear 505 through an axle rod. A long slide 506 is fixedly installed on the side of the cleaning scraper 4, and a rack 507 is fixedly installed on the side of the long slide 506. The rack 507 is transmission-connected to the third gear 505.

[0027] When the main control motor 501 is working, it controls the long rotating shaft 502 to rotate, and then controls the first gear 503 to rotate. Based on the meshing relationship between the first gear 503 and the second gear 504, the second gear 504 and the third gear 505 and the second gear 504 rotate accordingly. Then, based on the transmission relationship between the rack 507 and the third gear 505, the rack 507, the long slide 506, and the cleaning scraper 4 move synchronously. When the cleaning scraper 4 moves, the dust on the dustproof net 301 is scraped off.

[0028] See also Figure 1 , Figure 2 , Figure 4 Specifically, the oblique exhaust outlet 3 is a channel structure arranged at an angle of 60° downward, and the distance between any two adjacent oblique exhaust outlets 3 is equal, and the number of oblique exhaust outlets 3 on one side of the protection box 2 is not less than eight.

[0029] The eight oblique exhaust ports 3 can effectively ensure the exhaust area, and the downward tilted angle setting can prevent rain and snow from penetrating into the interior of the protective box 2 under windy conditions. At the same time, when the dust on the dustproof net 301 is scraped off, the gravity of the dust can be used to facilitate the dust to fall automatically.

[0030] Specifically, the number of teeth on the side edge of the third gear 505 is seventeen, and the teeth occupy two-thirds of the side surface of the third gear 505 .

[0031] When the teeth of the third gear 505 mesh with the rack 507 , the rotation of the third gear 505 will push the rack 507 to move. When any tooth of the third gear 505 is not in contact with the rack 507 , the rotation of the third gear 505 will not affect the rack 507 .

[0032] Specifically, a card holder 203 is fixedly mounted on the protection box 2, and the card holder 203 and the rack 507 and the long slide plate 506 are able to slide freely; A straight rod 5061 is fixedly mounted on the long slide plate 506, and a sliding hole 2031 is provided on the holder 203 to slide with the straight rod 5061. The straight rod 5061 passes through the sliding hole 2031 and is fixed with a limit joint 5062. A strong spring 5063 is sleeved on the side of the straight rod 5061, and both ends of the strong spring 5063 are respectively fixed to the top of the holder 203 and the side of the long slide plate 506, and the strong spring 5063 always keeps a compressed state.

[0033] In the initial state, the upper end surface of the limit joint 5062 is in close contact with the lower end surface of the holder 203. At this time, the pressure provided by the strong spring 5063 to the long slide 506 is greater than the sum of the gravity of the long slide 506, the rack 507 and the cleaning scraper 4. The main control motor 501 controls the third gear 505 to rotate, and then controls the rack 507, the long slide 506 and the cleaning scraper 4 to descend. The cleaning scraper 4 scrapes off the dust on the dustproof net 301 during the downward movement. At the same time, the straight rod 5061 slides and descends along the sliding hole 2031, and the strong spring 5063 is further compressed.

[0034] As the third gear 505 rotates, the teeth of the third gear 505 will be disengaged from the rack 507, and then the elastic force of the strong spring 5063 will cause the long slide 506, the rack 507, and the cleaning scraper 4 to rise and return to the initial state.

[0035] As the main control motor 501 continues to rotate, the teeth of the third gear 505 re-contact and mesh with the rack 507, thereby controlling the rack 507 to descend again, completing the continuous scraping of dust on the dustproof net 301 by the cleaning scraper 4.

[0036] Specifically, the length of the long slide plate 506 is not less than five times the length of the dustproof net 301 , and the long slide plate 506 slides along the side of the dustproof net 301 .

[0037] At any stage of the long slide plate 506 sliding up and down, the long slide plate 506 will effectively block the side of the dustproof net 301, preventing dust, rain and snow from entering the interior of the protection box 2 from the side of the dustproof net 301, thereby improving the protective effect of the protection box 2.

[0038] Embodiment 2: Based on the above embodiment 1, further description is given.

[0039] See also Figure 1 , Figure 2 , Figure 5 , Figure 6Specifically, the suspension assembly 6 includes a suspension control motor 601, which is fixed to the inner top of the protection box 2. The output end of the suspension control motor 601 is connected to a winding structure 602, on which two steel ropes 603 are wound. A frame sleeve 604 is provided on the outside of the refrigerator body 1, and both ends of the frame sleeve 604 are fixed to a steel rope 603 respectively.

[0040] When the suspension control motor 601 rotates, it cooperates with the winding structure 602 to control the winding or release of the steel rope 603, thereby controlling the frame sleeve 604 to rise or fall.

[0041] See also Figure 5 , Figure 6 Specifically, the winding structure 602 includes a main winding wheel 6021 and a slave winding wheel 6022. A spur gear 6023 is fixed on the same side of the main winding wheel 6021 and the slave winding wheel 6022. The two spur gears 6023 are of equal specifications and are meshed with each other. The output end of the suspension control motor 601 is connected to the spur gear 6023 on the main winding wheel 6021 through a coupling.

[0042] When the suspension control motor 601 is working, it controls one of the spur gears 6023 to rotate. Based on the meshing of the two spur gears 6023, it controls the main winding wheel 6021 and the slave winding wheel 6022 to rotate synchronously in opposite directions, thereby controlling the two steel ropes 603 to be synchronously wound or released.

[0043] See also Figure 2 , Figure 5 , Figure 6 Specifically, fixed pulleys 201 are fixedly installed on both sides of the inner top of the protection box 2, and the steel rope 603 passes through the fixed pulley 201 and turns, and the turned steel rope 603 is at a vertical angle.

[0044] The fixed pulley 201 is used to steer the steel rope 603 to avoid the steel rope 603 from contacting the refrigerator body 1 , thereby preventing the steel rope 603 from wearing the refrigerator body 1 .

[0045] Specifically, the frame sleeve 604 is a hollow steel structure, a protective cotton layer is laid on the inner side of the frame sleeve 604 , and the height of the frame sleeve 604 is not less than half of the height of the refrigerator body 1 .

[0046] The protective cotton layer can prevent the frame cover 604 from wearing the surface of the refrigerator body 1 . Meanwhile, the frame cover 604 can provide better support and loading for the refrigerator body 1 .

[0047] Specifically, a plurality of T-shaped connection joints 6041 are fixedly provided on the side of the frame sleeve 604 , and two limiting sliding grooves 202 are provided on the inner side wall of the protection box 2 , and the T-shaped connection joints 6041 slide inside the corresponding limiting sliding grooves 202 .

[0048] The limiting sliding groove 202 is used to limit the moving directions of the T-shaped connecting joint 6041, the frame sleeve 604, and the refrigerator body 1, thereby ensuring that the refrigerator body 1 can be stably lifted and lowered.

[0049] Working principle: When the refrigerator body 1 is working, the refrigerator body 1 is connected to the outside world through a hose to achieve liquid exchange.

[0050] During the use of the refrigerator body 1, the protection box 2 protects the refrigerator body 1 from rain, snow and dust. The structure of the sloping roof and the setting of the downward sloping exhaust vent 3 can prevent rain and snow from accumulating or entering the protection box 2, and the dustproof net 301 can prevent dust from entering the protection box 2.

[0051] Then, the cleaning control component 5 continuously cleans the dust on the dustproof net 301 to prevent dust accumulation and affect the cooling effect. Specifically, when the main control motor 501 is working, the long rotating shaft 502 is controlled to rotate, and then the first gear 503 is controlled to rotate. Based on the meshing relationship between the first gear 503 and the second gear 504, the second gear 504 and the third gear 505 are rotated accordingly. Then, based on the transmission relationship between the rack 507 and the third gear 505, the rack 507, the long slide plate 506, and the cleaning scraper are driven. 4 moves downward synchronously, and the cleaning scraper 4 completes the scraping of dust on the dustproof net 301 when moving. When the third gear 505 rotates to a certain extent, the teeth of the third gear 505 are disengaged from the rack 507, and then the elastic force of the strong spring 5063 causes the long slide plate 506, the rack 507, and the cleaning scraper 4 to rise. As the main control motor 501 continues to rotate, the teeth of the third gear 505 re-contact and mesh with the rack 507, thereby controlling the rack 507 to descend again, and completing the continuous scraping of dust on the dustproof net 301 by the cleaning scraper 4.

[0052] When encountering a long period of rainy or snowy weather, the suspension assembly 6 is used to increase the height of the refrigerator body 1 to greatly reduce the degree of moisture in the refrigerator body 1. Specifically, when the suspension control motor 601 rotates, one of the spur gears 6023 is controlled to rotate. Based on the engagement of the two spur gears 6023, the main winding wheel 6021 and the slave winding wheel 6022 are controlled to rotate synchronously in opposite directions, thereby controlling the two steel ropes 603 to be wound synchronously, thereby controlling the frame sleeve 604 to rise.

[0053] In summary, the use of the entire device can be completed. The device can prevent dust accumulation on the refrigerator body 1 during heat dissipation. At the same time, it can prevent the refrigerator body 1 from contacting rain and snow, reduce the moisture level of the refrigerator body 1, and ensure the refrigeration effect of the refrigerator body.

[0054] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
