Description

Technical Field

[0001] This utility model relates to the field of freezer door technology, specifically a glass door for freezers. Background Technology

[0002] A search revealed CN 218238012 U, a patent for a double-layered glass door for a commercial freezer. This patent describes a double-layered glass door for a commercial freezer, providing excellent insulation and preventing condensation. One layer of the door is made of acrylic material, effectively reducing the weight of the door and the pushing force required to slide it. The glass door uses a pulley structure, which effectively reduces friction between the glass door and the freezer opening, improving smoothness and user experience. A vacuum chamber is included, and molecular sieves are placed inside the vacuum chamber to effectively improve the insulation effect and prevent water vapor from condensing in the vacuum chamber, thus preventing condensation.

[0003] However, this patent has the following drawbacks;

[0004] 1) While the double-glazed door can prevent moisture from condensing in the vacuum chamber, the refrigerator door is opened and closed frequently, which reduces its sealing performance. Moisture can still enter the vacuum layer, leading to a decrease in the moisture absorption capacity of the molecular sieve and causing frost to form on the glass body.

[0005] 2) The molecular sieve needs to be replaced after its performance deteriorates. However, since the molecular sieve is in a vacuum layer, the entire glass body needs to be replaced during maintenance.

[0006] Therefore, a glass door for freezers is proposed to solve the above problems. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a glass door for freezers that is easy to maintain and solves the technical problem of declining molecular sieve performance and inconvenient replacement.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a glass door for a freezer, comprising a door body, on which two glass bodies are sealed and formed into a vacuum layer. The door body is provided with an installation hole and a through hole. A connecting mechanism is provided on the door body, and a sealing plate inserted into the installation hole is connected to the connecting mechanism. An activated carbon plate is detachably mounted on one end of the sealing plate inserted into the sealing hole. The door body is also provided with a connecting mechanism, and an air valve is provided on both the connecting mechanism and the through hole to control the air pressure within the vacuum layer.

[0009] Furthermore, a sealing groove communicating with the mounting hole is provided on the mounting hole, and a sealing ring adapted to the sealing groove is provided on the sealing plate and inserted into the sealing groove to seal the vacuum spacer.

[0010] Furthermore, a connecting plate is provided on the side of the sealing plate that is inserted into the vacuum partition, and an activated carbon plate is fixed to the connecting plate by bolt threads.

[0011] Furthermore, the connecting mechanism includes a connecting frame disposed on the door body, a connecting rod movably disposed on the connecting frame, one end of the connecting rod being fixed to the sealing plate, and the other end being fixedly connected to a handle, a spring being fitted and fixed on the connecting rod, and one end of the spring being fixed to the sealing plate, and the other end being fixed to the connecting frame.

[0012] Furthermore, limit grooves are provided on both ends of the connecting frame, and sliders are provided on both ends of the sealing plate, which are slidably connected to the limit grooves through the sliders.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects: the sealing plate seals the vacuum partition by connecting the mechanism and by evacuating the air through the air valve. When the activated carbon plate needs to be replaced, the air valve is opened to allow air to enter the vacuum chamber. Then, the activated carbon plate is extracted from the vacuum chamber by connecting the mechanism to complete the quick replacement. Afterwards, the connection between the glass body and the sealing door is resealed by sealing to facilitate the overall maintenance of the glass body door. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figure 1-5In this embodiment, a glass door for a freezer includes a door body 1. Two glass bodies 2 are sealed on the door body 1, forming a vacuum layer between the two glass bodies 2. The door body 1 is provided with an installation hole and a through hole. A connecting mechanism is provided on the door body 1, and a sealing plate 6 inserted into the installation hole is connected to the connecting mechanism. An activated carbon plate 9 is detachably provided on one end of the sealing plate 6 inserted into the sealing hole. The door body 1 is also provided with a connecting mechanism, and an air valve 13 is provided on the connecting mechanism and the through hole to control the air pressure in the vacuum layer.

[0022] In this embodiment, the vacuum partition formed by the double-layer glass body 2 improves the cold insulation and heat preservation effect. At the same time, the activated carbon plate 9 can adsorb the water vapor in the vacuum partition after its performance deteriorates, further preventing condensation in the glass body 2. Meanwhile, the activated carbon plate 9 can be extracted from the vacuum partition through the connecting mechanism for replacement, and the vacuum partition is vacuum sealed again, thereby improving the overall performance of the door body 1.

[0023] Preferably, as another embodiment of the present invention, a sealing groove 15 communicating with the mounting hole 14 is provided on the mounting hole 14, and a sealing ring 12 adapted to the sealing groove 15 is provided on the sealing plate 6 and inserted into the sealing groove 15 to seal the vacuum spacer.

[0024] In this invention, the sealing ring 12 can be inserted into the sealing groove 15 to seal the mounting hole 14. When the vacuum partition is in a vacuum state, the sealing ring 12 and the sealing groove 15 are in an adsorption state. It is only convenient to separate the sealing ring 12 from the sealing groove 15 after opening the air valve 13.

[0025] Preferably, as another embodiment of the present invention, a connecting plate 8 is provided on the side of the sealing plate 6 that is inserted into the vacuum partition, and an activated carbon plate 9 is threadedly fixed on the connecting plate 8 by bolts 10.

[0026] In this invention, the activated carbon plate 9 adsorbs the water vapor in the vacuum partition, preventing water vapor from accumulating on the glass body 2 door. The activated carbon plate 9 is fixed by the spiral connecting plate 8, making the activated carbon plate 9 stable and preventing the door 1 from becoming loose when opening and closing.

[0027] Preferably, as another embodiment of the present invention, the connecting mechanism includes a connecting frame 3 disposed on the door body 1, a connecting rod 4 movably disposed on the connecting frame 3, one end of the connecting rod 4 being fixed to the sealing plate 6, and the other end being fixedly connected to a handle 7, and a spring 5 being fitted and fixed on the connecting rod, with one end of the spring 5 being fixed to the sealing plate 6 and the other end being fixed to the connecting frame 3.

[0028] In this embodiment, when the activated carbon plate 9 needs to be replaced, the handle 7 is pulled to move the sealing plate 6 and compress the spring 5, so that the sealing ring 12 on the sealing plate 6 is separated from the sealing groove 15. At the same time, the connecting plate 8 and the activated carbon plate 9 are pulled out from the vacuum compartment and the activated carbon plate 9 is disassembled and replaced.

[0029] Preferably, as another embodiment of the present invention, the connecting frame 3 has a limiting groove on both ends, and the sealing plate 6 has a slider 11 on both ends, and the slider 11 is slidably connected to the limiting groove.

[0030] In this invention, the movement of the sealing plate 6 is limited by the slider 11 and the limiting groove, so that the sealing plate 6 moves in a straight line and drives the sealing ring 12 to dock with the sealing groove 15.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
