Abstract
Description
Technical Field
[0001] This utility model relates to the field of daily necessities technology, and more specifically, to a self-heating refrigerator defroster. Background Technology
[0002] A refrigerator is a refrigeration device that maintains a constant low temperature. It is also a consumer product that keeps food or other items at a constant low temperature. When a refrigerator is used for a long time, the condensate inside the refrigerator may freeze due to the temperature setting being too low, causing condensation to form on the evaporator, cooling coils, etc. It may also be due to the aging or damage of the refrigerator door seal, allowing outside air to enter and condense upon contact with the cold air. Alternatively, improper food storage, such as food containing a lot of moisture and not being properly sealed, can cause water vapor to evaporate and condense. In addition, a blocked drain can prevent condensate from draining and cause it to freeze.
[0003] Because ice can obstruct the flow of cold air and reduce the internal space of a refrigerator, it usually needs to be defrosted after prolonged use. Currently, the refrigerator is typically de-powered during defrosting, and the melted ice is removed using tools such as a scraper. Since this step requires waiting for the refrigerator to cool down, hot water or salt water is sprayed to loosen the ice. While this method can quickly defrost, it requires advance preparation and is time-consuming. Furthermore, the hot water gradually loses temperature during the defrosting process, requiring the user to replace it a second time, increasing the workload. Therefore, this method needs improvement and optimization. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a self-heating refrigerator defroster, which has the advantages of self-heating and easy replacement.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-heating refrigerator defroster, comprising an ice-removing shovel, a handle fixedly installed on the right side of the ice-removing shovel, and ice-crushing teeth fixedly installed on the left side of the ice-removing shovel;
[0006] The ice-removing shovel has a heating chamber inside, and a heat-conducting groove is provided on the left side of the heating chamber. The heating chamber and the heat-conducting groove are connected to each other. A placement frame is movably installed inside the heating chamber. Positioning blocks are fixedly installed at both ends of the front side of the placement frame. A hand-tightening bolt is threaded inside the positioning block. One end of the hand-tightening bolt passes through the inner wall of the ice-removing shovel and is threadedly connected to the ice-removing shovel. The placement frame is fixed inside the heating chamber by the hand-tightening bolt. A heat-conducting pipe is provided inside the ice-crushing teeth. The heat-conducting pipe and the heat-conducting groove are connected to each other. A vent hole is fixedly installed between each group of ice-crushing teeth.
[0007] As a preferred embodiment of this utility model, the placement frame is used to place the self-heating pack, and water holes are provided at both the left and right ends of the placement frame, and a groove is provided on the front side of the placement frame.
[0008] As a preferred technical solution of this utility model, a water inlet is fixedly opened on the rear side of the de-icing shovel, the water inlet and the heating chamber are interconnected, and a cap is threaded onto the outer wall of the water inlet.
[0009] As a preferred embodiment of this invention, the vent is covered with a waterproof and breathable membrane, and the vent is used to discharge water vapor.
[0010] As a preferred technical solution of this utility model, the bottom of the ice-removing shovel is provided with rotating grooves at both the front and rear ends, and a connecting rod is rotatably installed inside the rotating groove. A water-absorbing roller is rotatably installed between the two sets of connecting rods.
[0011] As a preferred embodiment of this utility model, a V-shaped spring is provided inside the rotating groove, and the connecting rod and the inner wall of the rotating groove are elastically connected by the V-shaped spring.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model, through the setting of a heating chamber inside the de-icing shovel, allows workers to place the self-heating pack into the heating chamber through a placement frame. By injecting water, the water temperature rises, generating a large amount of hot air. At this time, the water temperature is conducted to the de-icing shovel and ice-crushing teeth, while the hot air is sprayed onto the ice surface through the vents, accelerating the melting of the ice layer. Compared with traditional devices, this device requires less preparation time, does not require the use of brine or boiling water, improves de-icing efficiency, and the self-heating pack can continuously provide heat for a period of time, reducing the time for hot water replacement and improving user satisfaction.
[0014] 2. This utility model, through the setting of the water-absorbing roller, ensures that the connecting rod is always subjected to a thrust from the V-shaped spring when the user uses the device for defrosting. This thrust keeps the water-absorbing roller in constant contact with the inner wall of the refrigerator, further absorbing the dripping water. Compared with traditional devices, this device can effectively reduce water accumulation during refrigerator defrosting, effectively improve user satisfaction, reduce the cleaning burden after defrosting, and improve defrosting efficiency.

Detailed Implementation
[0023] 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.
[0024] like Figures 1 to 7 As shown, this utility model provides a self-heating refrigerator defroster, including an ice scraper 1, a handle 2 fixedly installed on the right side of the ice scraper 1, and ice-crushing teeth 3 fixedly installed on the left side of the ice scraper 1.
[0025] The ice scraper 1 has a heating chamber 17 inside, and a heat conduction groove 4 is provided on the left side of the heating chamber 17. The heating chamber 17 and the heat conduction groove 4 are connected to each other. A placement frame 5 is movably installed inside the heating chamber 17. Positioning blocks 18 are fixedly installed on both the left and right ends of the front side of the placement frame 5. A hand-tightening bolt 8 is threaded inside the positioning block 18. One end of the hand-tightening bolt 8 passes through the inner wall of the ice scraper 1 and is threadedly connected to the ice scraper 1. The placement frame 5 is fixed inside the heating chamber 17 by the hand-tightening bolt 8. A heat conduction pipe 11 is provided inside the ice crushing tooth 3. The heat conduction pipe 11 and the heat conduction groove 4 are connected to each other. A vent hole 12 is fixedly installed between each set of ice crushing teeth 3.
[0026] When de-icing is required, the worker first rotates the two sets of hand-tightening bolts 8 to disengage them from the inside of the de-icing scraper 1. Then, the worker pulls the placement frame 5 outwards through the pull groove 7. Next, the worker places the self-heating pack into the placement frame 5, then resets it and rotates the hand-tightening bolts 8 to install it inside the heating chamber 17. The worker then rotates the cap 10 to open the water inlet 9 and fills the heating chamber 17 with water. After filling, the worker seals the water inlet 9 with the cap 10. At this point, the quicklime inside the self-heating pack reacts with the water to form slaked lime (calcium hydroxide), releasing a large amount of heat and causing the water temperature to rise rapidly. Furthermore, since the heating chamber 17, the heat conduction groove 4, and the heat conduction pipe 11 are interconnected, the water will heat the de-icing shovel 1 and the ice crusher 3, achieving self-heating. When the workers are de-icing, the ice crusher 3 and the de-icing shovel 1 will contact the ice and accelerate the melting of the ice. Moreover, the water vapor generated by the heating inside the heating chamber 17 will be discharged to the outside through the vent 12. Furthermore, since the ice crusher 3 needs to always face the ice layer when de-icing, the vent 12 next to the ice crusher 3 will accelerate the melting of the ice. It is worth noting that the waterproof and breathable membrane covering the vent 12 is a polymer material with tiny pores. The size of these pores is large enough to allow water molecules to pass through in gaseous form, but not enough to allow liquid water to permeate.
[0027] With the heating chamber 17 inside the de-icing shovel 1, workers can insert the self-heating pack into the heating chamber 17 through the placement frame 5. By injecting water, the water temperature rises, generating a large amount of hot air. At this time, the water temperature is conducted to the de-icing shovel 1 and the ice-crushing teeth 3, while the hot air is sprayed onto the ice surface through the vent 12, accelerating the melting of the ice layer. Compared with traditional devices, this device requires less preparation time, does not require the use of brine or boiling water, improves de-icing efficiency, and the self-heating pack can continuously provide heat for a period of time, reducing the time for hot water replacement and improving user satisfaction.
[0028] The placement frame 5 is used to place the self-heating pack. Water holes 6 are provided at both ends of the placement frame 5, and a groove 7 is provided on the front side of the placement frame 5.
[0029] With the slot 7 in place, after de-icing is finished, the staff can pull out the placement box 5 through the slot 7 to drain the water and the self-heating pack.
[0030] The ice scraper 1 has a water inlet 9 fixedly opened on the rear side. The water inlet 9 and the heating chamber 17 are connected to each other. The outer wall of the water inlet 9 is threaded with a cap 10.
[0031] The vent 12 is covered with a waterproof and breathable membrane, and the vent 12 is used to discharge water vapor.
[0032] The waterproof and breathable membrane encased within the vent 12 is a polymer material with tiny pores. These pores are large enough to allow water molecules to pass through in gaseous form, but not large enough to allow liquid water to permeate.
[0033] The ice scraper 1 has rotating grooves 13 at both the front and rear ends of its bottom. A connecting rod 14 is rotatably installed inside the rotating groove 13, and a water suction roller 16 is rotatably installed between the two sets of connecting rods 14.
[0034] The rotating groove 13 is equipped with a V-shaped spring 15, and the connecting rod 14 and the inner wall of the rotating groove 13 are elastically connected by the V-shaped spring 15.
[0035] When the staff is defrosting, the connecting rod 14 and the inner wall of the rotating groove 13 are elastically connected by a V-shaped spring 15, so that the connecting rod 14 is always subjected to a pushing force. This pushing force will cause the water-absorbing roller 16 to always be in contact with the inner wall of the refrigerator. When the ice melts and flows downward, the water-absorbing roller 16 will absorb the water. Although the water-absorbing roller 16 cannot absorb all the water in the refrigerator, it can effectively reduce the accumulation of water in the refrigerator.
[0036] With the water-absorbing roller 16 in place, the connecting rod 14 is always subjected to a thrust from the V-shaped spring 15 when the user uses the device to defrost. This thrust keeps the water-absorbing roller 16 in contact with the inner wall of the refrigerator, further absorbing the dripping water. Compared with traditional devices, this device can effectively reduce water accumulation during refrigerator defrosting, effectively improve user satisfaction, reduce the cleaning burden after defrosting, and improve defrosting efficiency.
[0037] Working principle and usage process of this utility model:
[0038] When de-icing is required, the worker first rotates the two sets of hand-tightening bolts 8 to disengage them from the inside of the de-icing scraper 1. Then, the worker pulls the placement frame 5 outwards through the pull groove 7. Next, the worker places the self-heating pack into the placement frame 5, then resets it and rotates the hand-tightening bolts 8 to install it inside the heating chamber 17. The worker then rotates the cap 10 to open the water inlet 9 and fills the heating chamber 17 with water. After filling, the worker seals the water inlet 9 with the cap 10. At this point, the quicklime inside the self-heating pack reacts with the water to form slaked lime (calcium hydroxide), releasing a large amount of heat and causing the water temperature to rise rapidly. Furthermore, since the heating chamber 17, the heat conduction groove 4, and the heat conduction pipe 11 are interconnected, the water will heat the de-icing shovel 1 and the ice crusher 3, achieving self-heating. When the workers are de-icing, the ice crusher 3 and the de-icing shovel 1 will contact the ice and accelerate the melting of the ice. Moreover, the water vapor generated by the heating inside the heating chamber 17 will be discharged to the outside through the vent 12. Furthermore, since the ice crusher 3 needs to always face the ice layer when de-icing, the vent 12 next to the ice crusher 3 will accelerate the melting of the ice. It is worth noting that the waterproof and breathable membrane covering the vent 12 is a polymer material with tiny pores. The size of these pores is large enough to allow water molecules to pass through in gaseous form, but not enough to allow liquid water to permeate.
[0039] When the staff is defrosting, the connecting rod 14 and the inner wall of the rotating groove 13 are elastically connected by a V-shaped spring 15, so that the connecting rod 14 is always subjected to a pushing force. This pushing force will cause the water-absorbing roller 16 to always be in contact with the inner wall of the refrigerator. When the ice melts and flows downward, the water-absorbing roller 16 will absorb the water. Although the water-absorbing roller 16 cannot absorb all the water in the refrigerator, it can effectively reduce the accumulation of water in the refrigerator.
