Description

Technical Field

[0001] The utility model relates to the field of glass door and outer frame design, in particular to framed electric heating demisting glass and glass door for cold storage. Background Art

[0002] Cold storage is a type of refrigeration equipment. It refers to the use of artificial means to create an environment with a different temperature or humidity from the outdoor environment. It is also a constant temperature and humidity storage equipment for food, liquids, chemicals, medicines, vaccines, scientific experiments and other items. Cold storage is usually located near the transportation port or place of origin. Compared with refrigerators, cold storage has a larger refrigeration area and shares the same refrigeration principle.

[0003] In a food cold storage, in order to facilitate direct observation of the food stored in the cold storage, the cabinet door of the cold storage is set as a glass door. People can directly see the specific situation in the cold storage through the light-transmitting glass door, and then it is convenient to open the corresponding cabinet door to take out and put food. However, the existing glass door has the following defects:

[0004] 1. When used in cold storage, due to the large temperature difference between the inside and outside of the glass door, water vapor is easily attached to the surface of the glass. It is necessary to wipe off the misted water vapor on the surface of the glass before you can see the inside of the cold storage clearly, which makes it inconvenient to use;

[0005] 2. At present, the hinges of cold storage cabinet doors are generally not equipped with angle limiting structures, which makes the cabinet doors easy to be damaged during the opening and closing process.

[0006] According to defect 1, the prior art (announcement number: CN 219262186 U, announcement date: 2023.06.27) discloses an anti-fogging cold storage display cabinet glass door, which isolates the heat exchange inside and outside the display cabinet by setting a double-layer vacuum glass, further reducing the energy consumption of the equipment, and adding a layer of high-transmittance glass on the outside of the vacuum glass to further reduce the temperature difference between the outermost glass of the cabinet door and the room temperature, thereby reducing the probability of fogging of the cabinet door; however, the preparation cost of its double-layer vacuum glass structure is high, which is not conducive to popularization and use, and it is also impossible to completely avoid fogging, and it needs to be improved.

[0007] According to defect 2, there is no suitable solution in the prior art, and it is impossible to achieve automatic locking after opening or closing to a certain angle.

[0008] For this reason, it is necessary to newly design a kind of cold storage with framed electrically heated defog glass and glass door that can solve the above-mentioned two defects at the same time. Utility Model Content

[0009] In order to overcome the above-mentioned shortcomings, the utility model provides a technical solution that can solve the above-mentioned problems.

[0010] The framed electrically heated defog glass for cold storage comprises a glass layer, a transparent conductive layer, a glass outer frame and a cold storage outer frame; the transparent conductive layer is evenly arranged and installed on the inner surface of the glass layer, a heating wire is electrically connected and installed on the transparent conductive layer, the glass outer frame is fixedly installed around the outer side of the glass layer, and the outer edge of the transparent conductive layer is electrically connected and installed on the glass outer frame; the glass outer frame is hingedly installed inside the cold storage outer frame.

[0011] Furthermore: hollow hinge shafts are fixedly installed on the upper and lower sides of the cold storage outer frame, and hinge positions are formed on the upper and lower ends of the glass outer frame. The hollow hinge shafts are rotatably installed in the hinge positions one by one, and the glass outer frame is flipped open or flipped closed with the hollow hinge shaft as the center.

[0012] Furthermore: the transparent conductive layer is any one of an ITO film, a ZnO-based TCO film, a multi-element TCO film, a high-mobility TCO film, and a flexible transparent conductive film.

[0013] A glass door for a cold storage comprises an angle limiter and the above-mentioned electric heating defogger glass with a frame for the cold storage, wherein the angle limiter comprises a first hinged arm, a second hinged arm and a limiter spring; one end of the first hinged arm is hingedly mounted in an outer frame of the cold storage, the other end of the first hinged arm is inserted into one end of the second hinged arm with a clearance fit, and the other end of the second hinged arm is hingedly mounted on the glass outer frame; the limiter spring is fixedly mounted on the second hinged arm, one end of the first hinged arm is inserted into the second hinged arm and fixedly mounted with a limiter shaft, the outer end of the limiter spring is formed with an inner concave edge, and the limiter spring bends and deforms outwards when the inner concave edge abuts against the limiter shaft.

[0014] Further: one or more limiting shafts are provided, and when the inner concave edge abuts against one of the limiting shafts, the limiting spring piece bends and deforms outwards.

[0015] Furthermore: when the inner concave edge abuts against the limiting axis closest to the glass outer frame, the angle between the glass outer frame and the cold storage outer frame is 80°-100°.

[0016] Furthermore: when the inner concave edge abuts against the limiting axis farthest from the glass outer frame, the angle between the glass outer frame and the cold storage outer frame is 0°-5°.

[0017] Furthermore: a rubber sealing strip is fixedly installed on one side of the glass outer frame close to the cold storage outer frame, and when the glass outer frame is closed, the rubber sealing strip is tightly fitted in the matching gap between the glass outer frame and the cold storage outer frame.

[0018] Furthermore: a sliding groove is formed at one end of the second articulated arm close to the first articulated arm, and the first articulated arm is inserted into one end of the second articulated arm and slidably fitted in the sliding groove.

[0019] Furthermore: a door handle is integrally formed at the front edge of the glass frame.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] 1. Use the transparent conductive layer as the conductive material of the glass to produce conductive glass. When the conductive glass is used in the cold storage, since the transparent conductive layer is in a powered state, a small amount of heat will be generated when powered on, thereby preventing the temperature difference between the inside and outside of the cold storage from being too large. Through electric heating, the glass layer can be effectively prevented from fogging. There is no need to set up double-layer vacuum glass, the preparation cost is low, and it will also have a better anti-fog effect;

[0022] 2. Use the angle limiter to realize the angle limit when the glass frame is flipped open or flipped closed. When opening or closing the glass frame, one end of the first hinged arm will slide and fit in the second hinged arm. After opening or closing to a certain angle, the inner concave edge of the limit spring will abut against the limit shaft. When the limit spring is elastically reset, the limit shaft will be stuck on the bottom side of the limit spring, thereby providing a lock for the relative position between the first hinged arm and the second hinged arm, realizing the angle limit self-locking.

[0034] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments.

[0035] The components of the embodiments of the present invention generally described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

[0036] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0038] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] like Figure 1-8 As shown, the electric heating defog glass with frame for cold storage of the utility model comprises a glass layer 1, a transparent conductive layer 2, a glass outer frame 3 and a cold storage outer frame 4; the transparent conductive layer 2 is evenly arranged and installed on the inner surface of the glass layer 1, and a heating wire (not shown in the figure) is electrically connected and installed on the transparent conductive layer 2, so as to prevent the generation of condensed water by electric heating, thereby effectively defogging, and the glass outer frame 3 is fixedly installed around the outer side of the glass layer 1, and the outer edge of the transparent conductive layer 2 is electrically connected and installed on the glass outer frame 3; the glass outer frame 3 is hingedly installed in the cold storage outer frame 4;

[0040] The principle is: using the transparent conductive layer 2 as the conductive material of the glass, and then making conductive glass. When the conductive glass is used in the cold storage, since the transparent conductive layer 2 is in a powered state, a small amount of heat will be generated when powered, thereby preventing the temperature difference between the inside and outside of the cold storage from being too large. Through electric heating, the glass layer 1 can be effectively prevented from fogging. There is no need to set up double-layer vacuum glass, the preparation cost is low, and it will also have a better anti-fog effect.

[0041] Furthermore: hollow hinge shafts 6 are fixedly installed on the upper and lower sides of the cold storage outer frame 4, and hinge positions 5 are formed on the upper and lower ends of the glass outer frame 3. The hollow hinge shafts 6 are rotatably installed in the hinge positions 5 one by one, and the glass outer frame 3 is flipped open or flipped closed with the hollow hinge shafts 6 as the center; this can ensure the stable installation of the glass outer frame 3 in the cold storage outer frame 4, making the movement of the glass outer frame 3 when flipping open or closing more stable and smooth.

[0042] Furthermore: the transparent conductive layer 2 adopts any one of ITO film, ZnO-based TCO film, multi-element TCO film, high-mobility TCO film, and flexible transparent conductive film; there are many conductive transparent materials on the market, and one of them can be selected for use in the transparent conductive layer 2. Transparent conductive materials generally do not affect the light transmittance of the glass layer 1.

[0043] A glass door for a cold storage comprises an angle limiter 7 and the above-mentioned electric heating defogger glass with a frame for a cold storage, wherein the angle limiter 7 comprises a first hinged arm 71, a second hinged arm 72 and a limiter spring 73; one end of the first hinged arm 71 is hingedly mounted in the outer frame 4 of the cold storage, the other end of the first hinged arm 71 is inserted into one end of the second hinged arm 72 with a clearance fit, and the other end of the second hinged arm 72 is hingedly mounted on the glass outer frame 3; the limiter spring 73 is fixedly mounted on the second hinged arm 72, one end of the first hinged arm 71 inserted into the second hinged arm 72 is fixedly mounted on the limiter shaft 8, the outer end of the limiter spring 73 is formed with an inner concave edge 9, and the limiter spring 73 is bent and deformed outward when the inner concave edge 9 abuts against the limiter shaft 8;

[0044] The principle is: the angle limiter 7 can be used to achieve angle limitation when the glass outer frame 3 is flipped open or flipped closed. When opening or closing the glass outer frame 3, one end of the first hinged arm 71 will slide and fit in the second hinged arm 72. After opening or closing to a certain angle, the inner concave edge 9 of the limiting spring piece 73 will abut against the limiting shaft 8. When the limiting spring piece 73 is elastically reset, the limiting shaft 8 will be stuck on the bottom side of the limiting spring piece 73, thereby locking the first hinged arm 71 and the second hinged arm 72 to achieve angle locking.

[0045] Furthermore: one or more limit shafts 8 are provided, and when the inner concave edge 9 abuts against one of the limit shafts 8, the limit spring 73 bends and deforms outward; the number and installation position of the limit shafts 8 can be set according to actual needs, so that the first hinged arm 71 and the second hinged arm 72 can lock themselves after sliding to a certain distance from each other, thereby realizing automatic limiting after the glass frame 3 is opened or closed to a certain angle.

[0046] Furthermore: when the inner concave edge 9 abuts against the limiting axis 8 closest to the glass outer frame 3, the angle between the glass outer frame 3 and the cold storage outer frame 4 is 80°-100°; when the limiting spring piece 73 clamps the limiting axis 8 closest to the glass outer frame 3, the opening angle of the glass outer frame 3 is exactly 90°, which can facilitate the taking and placing of food.

[0047] Furthermore: when the inner concave edge 9 abuts against the limiting axis 8 farthest from the glass outer frame 3, the angle between the glass outer frame 3 and the cold storage outer frame 4 is 0°-5°; when the limiting spring piece 73 clamps the limiting axis 8 farthest from the glass outer frame 3, the opening angle of the glass outer frame 3 is just 0°, which can achieve self-locking of the glass outer frame 3 after closing.

[0048] Furthermore: a rubber sealing strip 10 is fixedly installed on one side of the glass outer frame 3 close to the cold storage outer frame 4. When the glass outer frame 3 is closed, the rubber sealing strip 10 is tightly fitted in the matching gap between the glass outer frame 3 and the cold storage outer frame 4; the setting of the rubber sealing strip 10 can increase the sealing performance, avoid air leakage in the cold storage, and ensure the freezing and heat preservation effect of the cold storage.

[0049] Furthermore: a sliding groove 11 is formed at one end of the second articulated arm 72 close to the first articulated arm 71, and the first articulated arm 71 is inserted into one end of the second articulated arm 72 and slidably fitted in the sliding groove 11; making the sliding fit between the first articulated arm 71 and the second articulated arm 72 more stable and smooth.

[0050] Furthermore, a door handle 12 is integrally formed at the front edge of the glass outer frame 3, which can facilitate opening or closing the glass door.

[0051] This embodiment does not impose any formal restrictions on the shape, material, structure, etc. of the utility model. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model are within the protection scope of the technical solution of the utility model.
