Description

Technical Field

[0001] The invention relates to the technical field of horizontal freezers, in particular to a horizontal freezer with a defrosting function. Background Art

[0002] Horizontal freezers are widely used in both home and commercial applications. Their main feature is the horizontal design, which makes the freezer closer to the ground, making it easier to access items while taking up less vertical space. This type of freezer is suitable for situations where a large amount of refrigeration or freezing space is required, such as large-scale household storage, catering, and supermarket product display.

[0003] Existing horizontal freezers usually do not have a defrosting function. When the freezer is used for a long time, the temperature difference between the inside of the freezer and the outside will cause frost to form on the insulation layer. The long-term accumulation of frost will not only cause the frost layer to be too thick, reducing the storage space in the freezer, but also be very inconvenient to clean. The staff needs to use tools to scrape off the frost layer. Since the frost will be too tightly attached to the insulation layer after cleaning, it will be more difficult to clean. It requires a lot of force to clean, and it is easy to scratch and damage the insulation layer, which affects the use of the freezer. Therefore, we propose a horizontal freezer with a defrosting function. Summary of the invention

[0036] Two springs are fixedly connected to the left side of the sealing plate 14, and the left sides of the two springs are fixedly connected to the left side of the inner wall of the refrigerator body 1. The right side of the sealing plate 14 is arranged in an arc shape, and a connecting block 142 is fixedly connected to the center of the left side of the sealing plate 14. The connecting block 142 is rotatably connected to the bottom of the pull rod 15 through a pin shaft. The sealing plate 14 will stretch the spring on the left side when it moves. When the electric push rod 3 is started to drive the push block 31 to reset, the sealing plate 14 is reset by the action of the left spring.

[0037] Two fixing frames 162 are fixedly connected to the center of the right side of the sealing plate 2 16, and the front and back sides of the top of the pull rod 15 are fixedly connected with fixing shafts 151.

[0038] A sealing plug 121 is provided at the top of the inner wall of the water tank 12, and the front and back sides of the sealing plug 121 are in contact with the inner wall of the water tank 12. A lifting frame 122 is fixedly connected to the bottom of the sealing plug 121, and two protrusions are fixedly connected to the right side of the lifting frame 122. A turntable 123 is provided on the right side of the lifting frame 122, and a roller 231 is fixedly connected to the left side of the turntable 123. A fixed seat 124 is provided on the right side of the turntable 123. A rotating rod 125 is rotatably connected inside the fixed seat 124. The right side of the rotating rod 125 passes through the right side of the water tank 12 and extends to the outside. A motor is fixedly connected to the right side of the water tank 12 126, the left output end of the motor 126 is fixedly connected to the right side of the rotating rod 125. By starting the motor 126 to drive the rotating rod 125 to rotate, the turntable 123 rotates together, and the turntable 123 drives the roller 231 to rotate together, and pushes the lifting frame 122 downward, and the lifting frame 122 drives the sealing plug 121 to move downward, thereby opening the opening, so that the internal water flow can smoothly enter the water tank 12, and then the water flow in the water tank 12 is discharged through the water outlet pipe 2 connecting the pipeline, so as to facilitate the discharge of the water flow generated inside the refrigerator body 1, so as to better clean it.

[0039] The sealing plug 121 is plugged into the top of the water tank 12, and the top of the sealing plug 121 extends into the interior of the refrigerator body 1. The outer surface of the roller 231 contacts one side corresponding to the two protrusions on the right side of the lifting frame 122. The bottom of the fixing seat 124 is fixedly connected to the bottom of the inner wall of the water tank 12. The left side of the rotating rod 125 is fixedly connected to the right side of the rotating disk 123. Through the two protrusions provided on the right side of the lifting frame 122, the roller 231 can smoothly push the lifting frame 122 through the cooperation with the protrusions when rotating. Since the front and back sides of the sealing plug 121 are in contact with the inner wall of the water tank 12, it can play a role of limiting and prevent the sealing plug 121 from tilting.

[0040] A groove is provided at the center of the left side of the inner wall of the refrigerator body 1, and the pull rod 15 is in the groove. An opening is provided at the top of the water tank 12, and the opening penetrates into the interior of the heat-insulating layer plate 11. The sealing plug 121 is adapted to the opening. When the water flow is discharged, the motor 126 drives the rotating rod 125 to rotate in the opposite direction. At this time, the turntable 123 drives the roller 231 to rotate upward, and drives the sealing plug 121 to reset upward through the lifting frame 122 to seal the opening.

[0041] A water outlet pipe 2 is fixedly connected to the front of the refrigerator body 1 , and the back of the water outlet pipe 2 penetrates the refrigerator body 1 and extends to the inside of the water tank 12 , and the water outlet pipe 2 and the water tank 12 are interconnected.

[0042] The air outlet pipe 131 and the flow chamber 18 are interconnected, and the sealing plug 121 is T-shaped. The sealing plug 121 is narrow at the top and wide at the bottom. The refrigerator 13 is started to generate cold air, and the cold air is discharged into the flow chamber 18 through the air outlet pipe 131. Then, the cold air in the flow chamber 18 is discharged into the insulation layer board 11 through the cold air inlet 113 to freeze the items on the insulation layer board 11.

[0043] When in use, the refrigerator 13 is started to generate cold air, and the cold air is discharged into the flow cavity 18 through the air outlet 131, and then the cold air in the flow cavity 18 is discharged into the insulation layer plate 11 through the cold air inlet 113, and the items on the insulation layer plate 11 are frozen. The refrigerator 13 transfers the heat inside the freezer to the external environment through the process of cyclic compression, condensation, throttling and evaporation, so as to maintain the low temperature state inside the freezer. When it is necessary to defrost the surface of the insulation layer plate 11, the electric push rod 3 is started to drive the push block 31 to move to the right. When the push block 31 contacts the sealing plate 14, it will push the sealing plate 14. At this time, the sealing plate 14 rotates on the freezer body 1 through the rotating shaft 141, and the sealing plate 14 will stretch the spring on the left side, and The pull rod 15 is driven downward by the action of the connecting block 142 and the pin shaft, and the top of the pull rod 15 drives the fixing frame 162 to move downward through the fixing shaft 151. Since the fixing shaft 151 slides in the fixing frame 162, the fixing frame 162 will drive the sealing plate 16 to flip downward. At this time, the bottom of the sealing plate 16 rotates on the rotating shaft 161. In this way, the sealing plate 14 will seal the top of the air outlet pipe 131, and the sealing plate 16 will be away from the air inlet groove 17 to open it. At this time, the cold air will not enter the flow cavity 18, and the external hot air will enter the flow cavity 18 through the air inlet groove 17, and enter the inside of the heat insulation layer plate 11 through the cold air inlet 113, so as to melt the frost layer attached to the surface of the heat insulation layer plate 11, thereby achieving the effect of defrosting. The heating wire 112 is heated by starting the heating device 4. The heating wire 112 relies on the Joule heating effect, that is, when current passes through a conductor, due to the existence of resistance, part of the electrical energy will be converted into thermal energy. After the heating wire 112 generates heat, the heat is transferred to the surface of the insulation layer plate 11, which can play the defrosting function again, thereby improving the defrosting effect. It can achieve a more efficient defrosting effect without affecting the freezing, and does not require subsequent cleaning by the staff. After use, the heating device 4 stops working, and the heating wire 112 is not heated at this time. The electric push rod 3 is started again to drive the push block 31 to reset. At this time, the sealing plate 14 is reset under the action of the left spring, and the top of the air outlet 131 is opened. At the same time, the sealing plate 14 will drive the sealing plate 2 16 to reset through the pull rod 15. , the sealing plate 16 seals the air inlet slot 17, and the cold air enters the flow chamber 18 again to continue the refrigeration work. During the defrosting process, the starter motor 126 drives the rotating rod 125 to rotate, and the turntable 123 rotates together and rotates on the fixed seat 124. The fixed seat 124 is used to support the rotating rod 125. The turntable 123 drives the roller 231 to rotate together and pushes the lifting frame 122 downward. The lifting frame 122 drives the sealing plug 121 to move downward, thereby opening the opening, so that the internal water flow can smoothly enter the water tank 12, and then the water flow in the water tank 12 is discharged through the water outlet pipe 2 connecting the pipe. Since the front and back sides of the sealing plug 121 are in contact with the inner wall of the water tank 12, it can play a role in limiting.To prevent the sealing plug 121 from tilting, when the water flow is discharged, the motor 126 drives the rotating rod 125 to rotate in the opposite direction, and the rotating disk 123 drives the roller 231 to rotate upward, and drives the sealing plug 121 to reset upward through the lifting frame 122 to seal the opening.
