Description

Technical Field

[0001] This application relates to the field of cold storage door technology, and more specifically, to a cold storage door that is easy to observe. Background Technology

[0002] An easy-to-observe cold storage door is a special type of door that maintains good thermal insulation performance while incorporating a visible area or observation structure. This allows personnel to easily check the interior of the cold storage without frequently opening the door, thereby reducing cold air loss and improving ease of use and energy efficiency.

[0003] Traditional observation windows require frequent manual cleaning of frost and water droplets, which is not only time-consuming and labor-intensive, reducing work efficiency, but also prone to operational errors due to untimely cleaning or unclear observation. In addition, some defrosting methods cannot achieve complete and effective defrosting of the observation window, easily resulting in localized residues that continuously affect the observation results.

[0004] In view of this, this application proposes a cold storage door that is easy to observe. Utility Model Content

[0005] The purpose of this application is to provide a cold storage door that is easy to observe, thereby solving the technical problems mentioned in the background art.

[0006] This application provides a cold storage door that is easy to observe, including a cold storage door body. An installation opening is provided through the upper part of the interior of the cold storage door body. A fixing frame is fixedly connected inside the installation opening. The upper and lower ends of the fixing frame are spaced apart from the inner wall of the installation opening. A tempered glass plate is fixedly connected inside the fixing frame. A cleaning mechanism is provided around the fixing frame.

[0007] The cleaning mechanism includes a movable frame located behind the fixed frame. A movable strip is provided in front of the fixed frame. A scraper is fixedly connected to the end face of the movable strip near the movable frame, and the scraper is in contact with the tempered glass plate. A heating plate is fixedly connected inside the movable frame. A heat insulation sheet is fixedly connected to the end face of the movable frame near the tempered glass plate, and the heat insulation sheet is in contact with the tempered glass plate.

[0008] Optionally, extension grooves are provided on the upper and lower sides of both sides of the inner wall of the mounting port, and sealing grooves are provided on the upper and lower sides of the inner wall of the mounting port, with the sealing grooves extending into the extension grooves.

[0009] Optionally, connecting strips are fixedly connected above and below the movable frame and the movable strip, and the upper and lower ends of the connecting strips are respectively in contact with the inner wall of the mounting port and the outer wall of the fixed frame.

[0010] Optionally, extension strips are fixedly connected to both sides of the connecting strip, and the extension strips extend into the extension groove, with the outer wall of the extension strip precisely fitting the inner wall of the extension groove.

[0011] Optionally, a sealing strip is fixedly connected to the end face of the extension strip and the connecting strip near the sealing groove, and the sealing strip is located inside the sealing groove.

[0012] Optionally, a handle is fixedly connected to the end face of the moving bar away from the moving frame.

[0013] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0014] 1. This application utilizes a heating plate to release heat, which in turn heats the tempered glass panel, rapidly melting surface frost. Simultaneously, the heat insulation sheet wipes away water droplets from the melted frost, and a scraper further removes water droplets from the other side of the tempered glass panel. These multiple measures ensure the observation window remains consistently clear. This eliminates the need for frequent manual cleaning, allowing staff to quickly and clearly observe the interior of the cold storage, improving work efficiency and preventing operational errors caused by unclear visibility.

[0015] Workers pull the moving bar with a handle, which moves the connecting bar, moving frame, and heating plate synchronously to achieve full heating of the tempered glass plate. This flexible moving design ensures that all areas of the tempered glass plate are effectively heated, avoiding localized frost residue and further improving defrosting effect and viewing clarity.

[0016] 2. This application utilizes a method where, during the movement of the connecting strip, the extension strip moves within the extension groove, and the sealing strip slides within the sealing groove, consistently blocking the gap between the fixing frame and the mounting opening. This effectively prevents external temperature from entering the cold storage, avoids temperature fluctuations within the cold storage due to observation and operation, maintains the stability of the cold storage environment, ensures the quality and safety of stored goods, and reduces energy consumption increases caused by temperature changes.

[0017] The heat insulation sheet, while transferring heat to melt frost, prevents direct contact between the heating plate and the tempered glass plate, avoiding damage to the tempered glass plate due to excessive temperature. The sealing design of the sealing strip and extension strip reduces the corrosion of the internal structure of the device by external moisture, dust, etc. This dual protection mechanism effectively protects the core components of the device, extends the service life of the equipment, and improves the reliability and durability of the device.

Detailed Implementation

[0022] The present application will be further described in detail below with reference to the accompanying drawings.

[0023] Reference Figures 1-3 This application provides a cold storage door that is easy to observe, including a cold storage door body 1. An installation opening 2 is provided through the upper part of the interior of the cold storage door body 1. A fixing frame 3 is fixedly connected inside the installation opening 2. The upper and lower ends of the fixing frame 3 are spaced apart from the inner wall of the installation opening 2. A tempered glass plate 4 is fixedly connected inside the fixing frame 3. A cleaning mechanism 5 is provided around the fixing frame 3. The cleaning mechanism 5 includes a movable frame 501 located behind the fixing frame 3, and a movable strip 502 located in front of the fixing frame 3. The movable strip 502 is close to the movable frame 501. A scraper 503 is fixedly connected to the end face of the movable frame 501, and the scraper 503 is in close contact with the tempered glass plate 4. A heating plate 509 is fixedly connected inside the movable frame 501. A heat insulation sheet 508 is fixedly connected to the end face of the movable frame 501 near the tempered glass plate 4, and the heat insulation sheet 508 is in close contact with the tempered glass plate 4. A handle 504 is fixedly connected to the end face of the movable strip 502 away from the movable frame 501. Heat is released through the heating plate 509, and the heat insulation sheet 508 heats the tempered glass plate 4, which can quickly melt the frost on the surface. At the same time, the heat insulation sheet 508 can wipe away the water droplets after the frost melts, and together with the scraper 503, it can scrape off the water droplets on the other side of the tempered glass plate 4. Multiple measures ensure that the observation window always remains clear. This allows staff to quickly and clearly observe the inside of the cold storage without frequent manual cleaning, improving work efficiency and avoiding operational errors caused by unclear observation.

[0024] The operator pulls the moving bar 502 via the handle 504, which moves the connecting bar 505, the moving frame 501, and the heating plate 509 synchronously, achieving full heating of the tempered glass plate 4. This flexible moving design ensures that all areas of the tempered glass plate 4 are effectively heated, avoiding localized frost residue and further improving defrosting effect and viewing clarity.

[0025] Extension grooves 6 are provided on the upper and lower sides of both sides of the inner wall of the mounting port 2. Sealing grooves 7 are provided on the upper and lower sides of the inner wall of the mounting port 2, and the sealing grooves 7 extend into the extension grooves 6. Connecting strips 505 are fixedly connected to the upper and lower sides of the moving frame 501 and the moving strip 502, and the upper and lower ends of the connecting strips 505 are respectively in contact with the inner wall of the mounting port 2 and the outer wall of the fixed frame 3. Extension strips 506 are fixedly connected to both sides of the connecting strips 505, and the extension strips 506 extend into the extension grooves 6. The outer wall of the extension strips 506 is precisely in contact with the inner wall of the extension grooves 6. Sealing strips 507 are fixedly connected to the end faces of the extension strips 506 and the connecting strips 505 near the sealing grooves 7, and the sealing strips 507 are located in the sealing grooves 7. As the connecting strips 505 move, the extension strips 506 move in the extension grooves 6, and the sealing strips 507 slide in the sealing grooves 7, always blocking the gap between the fixed frame 3 and the mounting port 2. It effectively prevents external temperatures from entering the cold storage, avoids temperature fluctuations inside the cold storage due to observation and operation, maintains the stability of the cold storage environment, ensures the quality and safety of stored goods, and reduces the problem of increased energy consumption caused by temperature changes.

[0026] The heat insulation sheet 508, while transferring heat to melt frost, prevents the heating plate 509 from directly contacting the tempered glass plate 4, avoiding damage to the tempered glass plate 4 due to excessive temperature. The sealing design of the sealing strip 507 and the extension strip 506 reduces the corrosion of the internal structure of the device by external moisture, dust, etc. This dual protection mechanism effectively protects the core components of the device, extends the service life of the equipment, and improves the reliability and durability of the device.

[0027] Working principle: When it is necessary to observe the inside of the cold storage, the staff activates the heating plate 509. The heating plate 509 releases heat to heat the tempered glass plate 4 through the heat insulation sheet 508. The staff pulls the moving bar 502 through the handle 504. The movement of the moving bar 502 drives the connecting bar 505 and the moving frame 501 to move synchronously, so that the heating plate 509 can heat the tempered glass plate 4 evenly, melting the frost on the surface of the tempered glass plate 4. At the same time, the heat insulation sheet 508 will wipe away the water droplets from the melted frost, making it easier for the staff to observe the inside of the cold storage. As the moving bar 502 moves, it will also drive the scraper 503 to move. The movement of the scraper 503 will scrape off the water droplets on the other side of the tempered glass plate 4, thereby improving the clarity of the tempered glass plate 4.

[0028] During the movement of the connecting strip 505, the extension strips 506 on both sides will move within the extension groove 6. Simultaneously, the sealing strip 507 on the extension strip 506 slides within the sealing groove 7. Throughout the movement of the moving frame 501, the moving strip 502, and the connecting strip 505, the extension strip 506 and the sealing strip 507 continuously block the gap between the fixed frame 3 and the mounting opening 2, preventing external temperature from interfering with the temperature inside the cold storage. After wiping the tempered glass plate 4, the heating plate 509 can be turned off.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
