Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, specifically to a refrigeration device that prevents internal icing and sticking. Background Technology

[0002] Refrigeration equipment is a device that maintains a low internal temperature through a refrigeration structure. Household refrigerators and freezers fall into the category of refrigeration equipment. However, existing refrigeration equipment still has certain defects in use. Existing refrigeration equipment removes frost by evaporating hot air, which makes the frost melt slowly. If the frost is too thick, the temperature cannot drop, resulting in high power consumption and affecting the life of the compressor in the long run.

[0003] Patent CN216814791U discloses a refrigeration device with anti-icing effect. It fills a water tank with clean water through an inlet pipe, and then uses a PLC controller to control a water pump to draw water from the tank through a universal metal pipe and spray it onto the surface of the refrigeration unit through a nozzle. The sprayed water and melted ice flow down the surface of the refrigeration unit to the base, and then the sprayed water returns to the tank through a first drain pipe and a second inlet pipe, thus recycling the sprayed water. This simple and quick method avoids water waste and solves the problem of ice forming on the surface of the refrigeration unit during operation.

[0004] In the aforementioned patent, the refrigeration device solves the problems mentioned above. However, the refrigeration device in the patent still has the following problems: during the operation of the refrigeration device, water needs to be sprayed through the nozzle to melt the frost that condenses inside the device. However, the internal humidity of the refrigeration device increases during the water spraying process, and frost will still condense. Therefore, continuous water spraying is required, which can easily lead to increased energy consumption of the refrigeration device. At the same time, water droplets adhering to the inside of the device will aggravate the frost condensation, making it impossible to achieve a comprehensive anti-icing effect and reducing the stability of the refrigeration device in use.

[0005] To address the aforementioned issues, innovative designs are urgently needed based on the existing refrigeration equipment structure. Utility Model Content

[0006] The purpose of this invention is to provide a refrigeration device that prevents internal icing and adhesion, in order to solve the problem mentioned in the background art where, during the operation of the refrigeration device, water needs to be sprayed from a nozzle to melt the frost that condenses inside the device. However, the increased internal humidity caused by the water spraying process leads to frost condensation, requiring continuous water spraying, which can easily increase the energy consumption of the refrigeration device. At the same time, water droplets adhering to the inside of the device can aggravate frost condensation, failing to achieve a comprehensive anti-icing effect and reducing the stability of the refrigeration device in use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a refrigeration device for preventing internal icing and sticking, comprising a main body and a rotatable door mounted on the front end of the main body; the main body has a fixed side plate inside, with a placement plate at the upper end of the fixed side plate and a support foot at the lower end of the main body; the main body has two sets of conical connecting ports on its outer side, with an air outlet pipe and an air inlet pipe respectively connected to the end of the conical connecting ports away from the main body; a dehumidification structure is provided at the end of the air outlet pipe and the air inlet pipe that are close to each other; the opening and closing structure on the outer side of the main body can ensure the stability of the internal refrigeration effect of the main body.

[0008] Preferably, the dehumidification structure includes a dehumidification upper cover and a dehumidification lower cover, with both ends of the dehumidification upper cover and the dehumidification lower cover respectively connected to the air outlet pipe and the air inlet pipe, and the dehumidification upper cover and the dehumidification lower cover are sealed and snapped together. At the same time, the transparent water storage frame at the lower end of the dehumidification lower cover is provided with scale lines on the outside, and the transparent water storage frame is used to store the water flow that is separated inside the dehumidification upper cover and the dehumidification lower cover.

[0009] Preferably, the inner ends of the dehumidifying upper cover and the dehumidifying lower cover are provided with filter plates, and anhydrous calcium chloride plates are provided at equal intervals between the two sets of filter plates. The anhydrous calcium chloride plates can adsorb moisture in the air and condense it into water.

[0010] Preferably, a negative pressure fan is installed inside the air outlet pipe, and an arc-shaped ring is installed on the outside of the air outlet pipe and the air inlet pipe. The negative pressure fan provides power for the air circulation and dehumidification inside the refrigeration equipment.

[0011] Preferably, the two ends of the dehumidifying upper cover and the dehumidifying lower cover are respectively threaded with limiting tubes, and the inside of the limiting tubes is provided with tight rings, and the tight rings are in close contact with the arc rings to complete the sealing of the air outlet pipe and the air inlet pipe with the two ends of the dehumidifying upper cover and the dehumidifying lower cover.

[0012] Preferably, the opening and closing structure includes a mounting plate, which is installed inside the two sets of conical connecting ports. A sliding rod is slidably installed inside the mounting plate. A sealing element is provided at the end of the sliding rod away from the mounting plate and is sealed to the conical connecting port. A return spring is provided on the outside of the sliding rod to control the sealing element to automatically seal with the conical connecting port.

[0013] Preferably, the opening and closing structure further includes protective plates, and two sets of protective plates are respectively arranged inside the main body of the equipment corresponding to the air outlet pipe and the air inlet pipe. The protective plates prevent the air outlet pipe and the air inlet pipe from being blocked.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1.

Furthermore, by replacing the equipment with a low-cost anhydrous calcium chloride perforated plate, the initial performance of the refrigeration equipment can be maintained, effectively improving the stability of the refrigeration equipment against icing.

[0016] 2. Furthermore, by operating the negative pressure fan, the pressure can be automatically controlled to separate the sealing element from the conical connection port, thereby providing conditions for air circulation inside the equipment. When the negative pressure fan stops working, the sealing element and the conical connection port automatically seal under the action of the return spring, thereby ensuring the sealing effect inside the equipment and further ensuring the stability of the cooling effect of the refrigeration equipment.

[0017] 3. Furthermore, the protective plate prevents refrigerated items from entering the pipes and causing blockage, and the filter plate prevents water absorbed by the anhydrous calcium chloride plate from flowing into the pipes, thus ensuring the moisture absorption effect on the outside of the refrigeration equipment.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] In a specific embodiment, this utility model provides the following technical solution: a refrigeration device to prevent internal icing and sticking, such as... Figures 1-4 The basic operating process of the refrigeration equipment is shown in the figure.

[0030] The equipment body 1 and the switch door 2 rotatably installed at the front end of the equipment body 1; the equipment body 1 is provided with a fixed side plate 3 inside, and a placement plate 5 is provided at the upper end of the fixed side plate 3, and a support foot 4 is provided at the lower end of the equipment body 1; the equipment body 1 is provided with two sets of conical connection ports 6 on the outside, and the end of the conical connection port 6 away from the equipment body 1 is respectively connected to an air outlet pipe 7 and an air inlet pipe 12; the ends of the air outlet pipe 7 and the air inlet pipe 12 that are close to each other are provided with a dehumidification structure; the opening and closing structure provided on the outside of the equipment body 1 can ensure the stability of the cooling effect inside the equipment body 1.

[0031] When using this anti-icing and anti-sticking refrigeration equipment, an external power supply is required to power the internal electrical structure of the equipment. Before the equipment starts refrigeration, the refrigerated items need to be placed on the top of the placement plate 5 and the switch door 2 needs to be closed. At this time, the equipment can start refrigeration. During the refrigeration process, the negative pressure fan 8 will draw the air inside the main body 1 of the equipment to the dehumidifying lower cover 10. The anhydrous calcium chloride perforated plate 17 will absorb the moisture in the air (the anhydrous calcium chloride perforated plate 17 is a perforated plate made of anhydrous calcium chloride, which has a strong water absorption capacity, and the existing technology will not be further described here), reducing the air humidity inside the equipment and solving the problem of icing inside the equipment from the root, effectively improving the stability of the refrigeration equipment.

[0032] In one specific embodiment, such as Figures 1-9 As shown, in order to solve the problem that existing refrigeration equipment is difficult to stably prevent icing, the specific process of internal icing prevention of the equipment is disclosed.

[0033] The dehumidification structure includes a dehumidifying upper cover 9 and a dehumidifying lower cover 10. Both ends of the dehumidifying upper cover 9 and the dehumidifying lower cover 10 are respectively connected to the air outlet pipe 7 and the air inlet pipe 12, and are sealed and snapped together. A transparent water storage frame 11 is provided at the lower end of the dehumidifying lower cover 10, with scale lines on its outer side. The transparent water storage frame 11 is used to store the water that precipitates inside the dehumidifying upper cover 9 and the dehumidifying lower cover 10. Filter plates 16 are provided at both ends inside the dehumidifying upper cover 9 and the dehumidifying lower cover 10, and anhydrous calcium chloride perforated plates 17 are equidistantly arranged between the two sets of filter plates 16. The anhydrous calcium chloride perforated plate 17 can adsorb moisture in the air and condense it into water. The air outlet pipe 7 is equipped with a negative pressure fan 8, and the air outlet pipe 7 and the air inlet pipe 12 are equipped with arc rings 14 on the outside. The negative pressure fan 8 provides power for the internal air circulation and dehumidification of the refrigeration equipment. The two ends of the dehumidification upper cover 9 and the dehumidification lower cover 10 are respectively threaded with limit tubes 13, and the inside of the limit tube 13 is equipped with a tight ring 15. The tight ring 15 and the arc ring 14 are in close contact to complete the sealing of the air outlet pipe 7 and the air inlet pipe 12 with the two ends of the dehumidification upper cover 9 and the dehumidification lower cover 10.

[0034] When using this anti-icing and sticking refrigeration equipment, the negative pressure fan 8 needs to draw air from the main body 1 into the dehumidifying upper cover 9 and the dehumidifying lower cover 10, and then into the main body 1 through the air inlet pipe 12. The filter plate 16 can isolate the two ends of the anhydrous calcium chloride perforated plate 17 to prevent water from directly entering the air outlet pipe 7 and the air inlet pipe 12. At the same time, the moisture absorbed by the anhydrous calcium chloride perforated plate 17 will accumulate into water and fall into the transparent water storage frame 11, thereby reducing the moisture inside the main body 1. The air outlet pipe 7 and the air inlet pipe 12 are connected to the dehumidifying upper cover 9 and the dehumidifying lower cover 10 through the limiting pipe 13. The sealing effect of the connection between the pipes can be ensured by the arc ring 14 and the tight ring 15. The limiting pipe 13 can also ensure the stability of the upper and lower connections of the dehumidifying upper cover 9 and the dehumidifying lower cover 10. The scale lines on the outside of the transparent water storage frame 11 can be used to empty the water inside the transparent water storage frame 11 in time.

[0035] During the removal of the transparent water storage frame 11, the limiting tube 13 needs to be rotated to separate the limiting tube 13 from the air outlet pipe 7 and the air inlet pipe 12. After separation, the dehumidifying upper cover 9 and the dehumidifying lower cover 10 can be removed. Then, the two sets of limiting tubes 13 can be rotated again to separate the limiting tube 13 from the two ends of the dehumidifying upper cover 9 and the dehumidifying lower cover 10. At this time, the dehumidifying upper cover 9 and the dehumidifying lower cover 10 can be separated to replace the anhydrous calcium chloride orifice plate 17. At the same time, the water inside the transparent water storage frame 11 is poured out. Then, the new anhydrous calcium chloride orifice plate 17 is placed inside the dehumidifying lower cover 10. By reversing the above process, the dehumidifying upper cover 9 and the dehumidifying lower cover 10 can be installed between the air outlet pipe 7 and the air inlet pipe 12, so that the anhydrous calcium chloride orifice plate 17 can continue to dehumidify the inside of the equipment body 1. By removing the moisture inside the equipment body 1, the freezing inside the equipment can be effectively prevented, ensuring the stability of the refrigeration equipment.

[0036] Based on the above embodiments, such as Figures 1-7 The working process of the device for cooling is shown in the figure.

[0037] The opening and closing structure includes a mounting plate 18, which is installed inside two sets of conical connecting ports 6. A sliding rod 19 is slidably installed inside the mounting plate 18. A sealing element 20 is provided at the end of the sliding rod 19 away from the mounting plate 18 and is sealed to the conical connecting port 6. A return spring 21 is provided on the outside of the sliding rod 19 to control the sealing element 20 to automatically seal with the conical connecting port 6. The opening and closing structure also includes a protective plate 22. Two sets of protective plates 22 are respectively provided inside the main body 1 and correspond to the air outlet pipe 7 and the air inlet pipe 12. The protective plates 22 are provided to prevent the air outlet pipe 7 and the air inlet pipe 12 from being blocked.

[0038] When using this anti-icing and anti-sticking refrigeration equipment, the moisture inside the main body 1 needs to be discharged by opening the conical connection port 6. When the negative pressure fan 8 is working, the space between it and the outer conical connection port 6 will be in a negative pressure state. At this time, the seal 20 inside the conical connection port 6 will separate from the conical connection port 6, so that there is a gap between the conical connection port 6 and the seal 20 to facilitate the discharge of air inside the main body 1. During this process, the seal 20 will slide inside the mounting plate 18 through the sliding rod 19, and during the sliding process, the seal 20 will squeeze the return spring 21 and cause the return spring 21 to enter... When the negative pressure fan 8 contracts, the conical connection port 6 at the end away from the negative pressure fan 8 will also create a gap with its internal seal 20. The seal 20 is blown away from the conical connection port 6 by the air force of the negative pressure fan 8. At the same time, the return spring 21 inside the conical connection port 6 will contract to ensure the stability of the anhydrous calcium chloride orifice plate 17 in absorbing moisture from the air inside the equipment. When the negative pressure fan 8 stops working, the contracted return spring 21 will expand and push the seal 20 to seal with the conical connection port 6, ensuring the sealing effect inside the main body of the equipment 1, thereby ensuring the stability of the cooling effect inside the refrigeration equipment and increasing the overall practicality.
