Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel refrigerators, and more specifically to a welded stainless steel refrigerator. Background Art

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature. It is also a civilian product that keeps food or other items at a constant low temperature. The cabinet contains a compressor, an ice maker, a cabinet or box for freezing, and a storage box with a refrigeration device.

[0003] Welded stainless steel refrigerators are often used in restaurants and other catering industries. Their sturdy stainless steel inner liner is strong enough to carry a large amount of items and is not easy to break or deform. However, the stainless steel inner liner is not completely indestructible. Unlike traditional plastic inner liner that can be formed in one go, the stainless steel inner liner needs to be welded, and its welds are relatively weaker than the whole. The working environment of the stainless steel inner liner is special. It works in humid cold air for a long time, and its welds are easily corroded and holes appear. Moreover, its tiny openings are not easy to occur, which will greatly affect the refrigeration efficiency in the later stage. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a welded stainless steel refrigerator, which solves the problem that the welding parts of the stainless steel inner liner in the prior art are relatively weak compared to the whole, and the welding parts are easily corroded and have holes due to the special working environment of the stainless steel inner liner and long-term operation in humid cold air. Moreover, the small openings are not easy to occur, which will greatly affect the refrigeration efficiency in the later stage.

[0006] 2. Technical solution

[0007] To solve the above problems, the utility model adopts the following technical solutions.

[0008] A welded stainless steel refrigerator comprises a stainless steel refrigerator shell, a stainless steel door is rotatably connected to one side of the stainless steel refrigerator shell, a circular magnetic metal strip is fixedly connected to one side of the stainless steel door, a stainless steel liner is welded to the inner cavity of the stainless steel refrigerator shell, a circular magnetic sealing strip is fixedly connected to the weld between the stainless steel liner and the stainless steel refrigerator shell, a magnet layer is provided in the inner cavity of the circular magnetic sealing strip, and the circular magnetic sealing strip is adsorbed to the circular magnetic metal strip through the magnet layer;

[0009] A reinforcing strip 1 is fixedly connected to the top weld of the stainless steel inner liner, and three reinforcing strips 2 are fixedly connected to the side welds of the stainless steel inner liner. There are cavities between the reinforcing strips 1 and 2 and the stainless steel inner liner, and the cavities are connected to the circular magnetic sealing strip.

[0010] Furthermore, the stainless steel liner is unfolded into a T-shaped stainless steel plate.

[0011] Furthermore, a connecting hose is fixedly connected to one side of the circular magnetic sealing strip, an interface is fixedly connected to one end of the connecting hose, and the interface is threadedly connected to the reinforcing strip 1.

[0012] Furthermore, a hexagonal block is fixedly connected to the outer circumferential surface of the interface, and a sealing gasket is also sleeved on the outer circumferential surface of the interface.

[0013] Furthermore, the second reinforcement strip is in an inclined shape.

[0014] 3. Beneficial effects

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] (1) The stainless steel liner of the present invention is formed by bending and welding a whole piece of cut T-shaped stainless steel plate, which can greatly reduce the number of welds and improve the overall strength of the stainless steel liner. In addition, reinforcing strips 1 and 2 are further welded at the welds of the stainless steel liner to protect the original welds of the stainless steel liner. On the one hand, the overall strength of the stainless steel liner is further strengthened. On the other hand, the original welds can be effectively protected from being directly eroded by humid cold air. The humid cold air will first erode the welds between reinforcing strips 1 and 2 and the stainless steel liner before eroding the original welds, which greatly improves the service life of the stainless steel liner.

[0017] (2) When the reinforcing strips 1 and 2 of the present scheme are welded to reinforce the stainless steel inner liner, there is a cavity between the reinforcing strips 1 and 2 and the stainless steel inner liner, and the cavity is connected to the circular magnetic sealing strip. When the personnel closes the stainless steel door, the circular magnetic sealing strip will be squeezed. If a hole appears at the weld, the gas in the cavity will leak, which will lead to insufficient air pressure in the circular magnetic sealing strip. Due to the lack of air pressure restraint, when the personnel open the stainless steel door again, two phenomena will occur. First, the circular magnetic sealing strip will be pulled too long as the stainless steel door is opened, and second, the circular magnetic sealing strip will recover slowly or even fail to recover. At this time, it can be judged that there may be a hole in the welding place, or the circular magnetic sealing strip is aged, but the personnel can find the problem in time and deal with it in time to avoid affecting the refrigeration efficiency.

[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] Example

[0027] like Figure 1-5 As shown, a welded stainless steel refrigerator comprises a stainless steel refrigerator shell 1, a stainless steel door 2 is rotatably connected to one side of the stainless steel refrigerator shell 1, a circular magnetic metal strip 3 is fixedly connected to one side of the stainless steel door 2, a stainless steel inner liner 4 is welded to the inner cavity of the stainless steel refrigerator shell 1, a circular magnetic sealing strip 5 is fixedly connected to the weld between the stainless steel inner liner 4 and the stainless steel refrigerator shell 1, a magnet layer 51 is provided in the inner cavity of the circular magnetic sealing strip 5, and the circular magnetic sealing strip 5 is adsorbed to the circular magnetic metal strip 3 through the magnet layer 51;

[0028] A reinforcing strip 1 6 is fixedly connected to the top weld of the stainless steel inner liner 4 , and three reinforcing strips 2 7 are fixedly connected to the side welds of the stainless steel inner liner 4 . There is a cavity 8 between the reinforcing strip 1 6 and the reinforcing strip 2 7 and the stainless steel inner liner 4 , and the cavity 8 is connected to the circular magnetic sealing strip 5 .

[0029] When in use, reinforcing strips 1 6 and 2 7 are further welded at the weld of the stainless steel inner liner 4, which can protect the original weld of the stainless steel inner liner 4. On the one hand, the overall strength of the stainless steel inner liner 4 is further reinforced, and on the other hand, the original weld can be effectively protected from being directly eroded by moist cold air. The moist cold air will first erode the weld between the reinforcing strips 1 6 and 2 7 and the stainless steel inner liner 4 before eroding the original weld, which greatly improves the service life of the stainless steel inner liner 4. When the reinforcing strips 1 6 and 2 7 are welded and reinforced to the stainless steel inner liner 4, there is a cavity 8 between the reinforcing strips 1 6 and 2 7 and the stainless steel inner liner 4, and the cavity 8 is connected to the return-shaped The magnetic sealing strips 5 are connected. When the personnel closes the stainless steel door 2, the circular magnetic sealing strips 5 will be squeezed. If an opening appears at the weld, the gas in the cavity 8 will leak, which will cause insufficient air pressure in the circular magnetic sealing strips 5. Due to the lack of air pressure restraint, when the personnel opens the stainless steel door 2 again, two phenomena will occur. One is that the circular magnetic sealing strips 5 will be pulled too long as the stainless steel door 2 is opened, and the other is that the circular magnetic sealing strips 5 recover slowly or even cannot recover. At this time, it can be judged that an opening may appear at the welding point, or the circular magnetic sealing strips 5 are aged, but the personnel can discover the problem in time and deal with it in time to avoid affecting the refrigeration efficiency.

[0030] like Figure 1 and 5 As shown, the stainless steel liner 4 is unfolded into a T-shaped stainless steel plate.

[0031] When in use, the stainless steel inner liner 4 is formed by bending and welding a whole T-shaped stainless steel plate that has been cut, which can greatly reduce the number of welds and improve the overall strength of the stainless steel inner liner 4.

[0032] like Figure 2-3 As shown, a connecting hose 52 is fixedly connected to one side of the circular magnetic sealing strip 5, and an interface 53 is fixedly connected to one end of the connecting hose 52. The interface 53 and the reinforcing strip 6 are threadedly connected.

[0033] When the circular magnetic sealing strip 5 is damaged and needs to be replaced, the circular magnetic sealing strip 5 can be separated from the reinforcing strip 1 6 by unscrewing the interface 53 .

[0034] like Figure 3 As shown, a hexagonal block 54 is fixedly connected to the outer circumferential surface of the interface 53 , and a sealing gasket 55 is also sleeved on the outer circumferential surface of the interface 53 .

[0035] When the interface 53 needs to be disassembled, the hexagonal block 54 can better cooperate with tools such as a wrench, and the sealing gasket 55 can improve the sealing between the interface 53 and the reinforcing strip 6.

[0036] like Figure 1-2As shown, the reinforcing strip 2 7 is in an inclined shape.

[0037] When in use, the inclined reinforcing strip 7 and the inner wall of the stainless steel inner liner 4 form a triangular structure, further improving the strength of the stainless steel inner liner 4 after reinforcement.

[0038] In summary, the specific working process of this scheme is as follows: the stainless steel liner 4 is formed by bending and welding a whole T-shaped stainless steel plate, which can greatly reduce the number of welds and improve the overall strength of the stainless steel liner 4. In addition, reinforcing strips 1 6 and 2 7 are further welded at the welds of the stainless steel liner 4, which can protect the original welds of the stainless steel liner 4. On the one hand, the overall strength of the stainless steel liner 4 is further strengthened. On the other hand, the original welds can be effectively protected from being directly eroded by humid cold air. The humid cold air will first erode the welds between the reinforcing strips 1 6 and 2 7 and the stainless steel liner 4 before eroding the original welds, which greatly improves the service life of the stainless steel liner 4.

[0039] Among them, when the reinforcing strips 1 6 and 2 7 are welded and reinforced to the stainless steel inner liner 4, there is a cavity 8 between the reinforcing strips 1 6 and 2 7 and the stainless steel inner liner 4, and the cavity 8 is connected with the circular magnetic sealing strip 5. When the personnel closes the stainless steel box door 2, the circular magnetic sealing strip 5 will be squeezed. If an opening appears at the weld, the gas in the cavity 8 will leak, which will cause insufficient air pressure in the circular magnetic sealing strip 5. Due to the lack of air pressure restraint, when the personnel open the stainless steel box door 2 again, two phenomena will occur. One is that the circular magnetic sealing strip 5 will be pulled too long as the stainless steel box door 2 is opened, and the other is that the circular magnetic sealing strip 5 recovers slowly or even cannot recover. At this time, it can be judged that there may be an opening at the welding point, or the circular magnetic sealing strip 5 is aged, but the personnel can find the problem in time and deal with it in time to avoid affecting the refrigeration efficiency.

[0040] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
