Description

Technical Field

[0001] This utility model belongs to the field of refrigeration equipment technology, and in particular relates to a hollow glass door and a freezer. Background Technology

[0002] Insulating glass doors are widely used in refrigeration equipment such as freezers and refrigerators due to their excellent thermal insulation and light transmission properties. They primarily work by creating a hollow cavity between two or more panes of glass, utilizing the low thermal conductivity of air or inert gases to achieve good insulation while reducing heat transfer, thus achieving energy savings.

[0003] A double-glazed door typically consists of a door frame and double-glazed glass units. The double-glazed glass units are mainly composed of inner and outer glass panes positioned opposite each other. The door frame primarily serves to support and protect the double-glazed glass units. The double-glazed glass units are installed on the inside of the door frame to form the double-glazed door, creating a seal with the refrigerator cabinet to prevent cold air leakage.

[0004] The existing installation structure between the door frame and the insulating glass in double-glazed doors is quite complex. Methods such as screw fixing are cumbersome, requiring significant manpower and time. Furthermore, repair and replacement are inconvenient once damaged, reducing production efficiency. Some double-glazed doors also suffer from insufficient structural and connection strength. Under external impact or prolonged use, the connection between the door frame and the insulating glass can easily loosen, leading to decreased overall stability, reduced lifespan, and potentially even safety hazards such as glass breakage.

[0005] Furthermore, existing double-glazed door frames are prone to condensation, which not only affects the door's appearance but can also cause water droplets to drip, impacting the storage environment of items inside the freezer and potentially reducing the door's insulation performance. To achieve better defrosting or anti-condensation effects, some double-glazed doors use heating wire components or fill the space between the door frame and the double glazing with expanding foam. Adding heating wire increases material and maintenance costs. While filling with expanding foam, where the foam directly contacts the double glazing, can alleviate condensation to some extent, it makes replacing the double glazing glass inconvenient. When replacement is needed, the foam needs to be re-foamed, increasing maintenance costs. Utility Model Content

[0044] The hollow glass door 100 provided in this application can have various embodiments. The following specific embodiments are described in conjunction with the accompanying drawings. Figures 1 to 8 The present invention will be described in further detail below.

[0045] refer to Figure 1 The insulated glass door 100 may include a door frame 10 and an insulated glass 20, with the insulated glass 20 fitted inside the door frame 10.

[0046] In this embodiment, the door frame 10 provides support and fixation for the insulated glass 20, giving the door good integrity and stability. At the same time, the insulated glass 20 is conducive to the realization of functions such as sound insulation, heat insulation and heat preservation.

[0047] refer to Figures 1-6 The door frame 10 may include a door frame 1, which is located on the outer periphery of the insulated glass 20. The door frame 1 is L-shaped.

[0048] The L-shaped door frame 1 can better fit the shape of the door, providing more stable support and frame structure, enhancing the overall structural strength of the door, and ensuring the stability of the door during use.

[0049] The door frame 10 may include an inner door frame 2, which is connected between the door frame 1 and the insulated glass 20.

[0050] The inner frame 2 of the door serves as a transitional connection, making the connection between the door frame 1 and the insulated glass 20 tighter and more secure, improving the structural stability of the door, and also facilitating the installation and fixing of the insulated glass 20.

[0051] refer to Figure 5 The two ends of the inner frame 2 of the door are respectively engaged with the two ends of the door frame 1 to form the receiving space 4. (Refer to...) Figure 2 , Figure 3 The space 4 is filled with foaming agent 6.

[0052] The snap-fit ​​design facilitates the quick assembly and disassembly of the inner frame 2 and the door frame 1. The foaming agent 6 filling the accommodating space 4 provides good heat preservation, insulation and sealing, effectively reducing heat leakage. At the same time, it can prevent water vapor from condensing into water droplets at the door frame 1, thus eliminating the generation of condensation on the door frame 1.

[0053] Furthermore, by setting the foaming agent 6, a foam layer is formed between the door frame 1 and the inner door frame 2 after foaming. This reduces the use of heating wires and lowers costs, while also improving the structural strength and integrity of the door frame 10, reducing deformation of the door frame 10, and preventing loosening between components.

[0054] refer to Figure 4 The door frame 10 may include an outer door frame 3, which is interlocked with the inner door frame 2 to jointly define a mounting groove 5. The mounting groove 5 is used to install the insulated glass 20.

[0055] In this embodiment, the outer frame 3 of the door and the inner frame 2 of the door are interlocked to form an installation groove 5, which provides a stable installation position for the insulated glass 20, so that the inner frame 2 of the door and the outer frame 3 of the door simultaneously press the insulated glass 20 to achieve a stable state.

[0056] Furthermore, the inner frame 2 of the door is also engaged with the outer frame 1 of the door, so that the inner frame 2, the outer frame 3, and the outer frame 1 of the door together fix the insulated glass 20, ensuring the stable installation of the insulated glass 20, facilitating the replacement and maintenance of the insulated glass 20, and improving the overall aesthetics of the insulated glass door 100.

[0057] Meanwhile, in the above embodiments, the door frame 1 and the inner door frame 2 are connected by a snap-fit ​​method, and the inner door frame 2 and the outer door frame 3 are connected by a fastening method. When subjected to external forces, the various components cooperate and constrain each other, which not only makes installation convenient but also provides higher structural strength and effectively ensures the service life of the door.

[0058] Continue to refer to Figure 4 The insulated glass unit 20 includes an inner glass 72 and an outer glass 71 disposed opposite to each other. The inner glass 72 can be tempered glass, and the outer glass 71 can be tempered coated glass.

[0059] In this embodiment, both tempered glass and tempered coated glass have high strength and safety, which can improve the safety of the door. Furthermore, tempered coated glass has better heat insulation performance. By using tempered coated glass for the outer glass 71, the heat insulation effect and service life of the door are improved, while also enhancing the appearance quality of the door, making the insulated glass door 100 more aesthetically pleasing.

[0060] refer to Figure 2 , Figure 4 The outer frame 3 of the door abuts against the inner side of the inner glass 72, and the inner frame 2 of the door abuts against the outer side of the outer glass 71, ensuring the installation of the insulated glass 20.

[0061] In some embodiments of this application, the door frame 1 is made of iron, and the inner door frame 2 and the outer door frame 3 are made of PVC.

[0062] The above configuration makes the door frame 1 a piece of iron, which has high strength and rigidity, providing solid support and frame for the insulated glass door 100. This ensures that the insulated glass door 100 maintains its shape and is not easily deformed when subjected to external impact or long-term use, thus extending the service life of the door.

[0063] In this embodiment, by changing the material of the door frame 1, the strength and rigidity of the door frame 1 are ensured. Combined with the inner door frame 2 and outer door frame 3 made of PVC material, the weight of the door is reduced, effectively reducing energy consumption and the cost of the door.

[0064] Furthermore, in the design process of the insulated glass door 100 provided in this embodiment, the space 4 between the door frame 1 and the inner frame 2 can be pre-filled with foaming agent 6. After foaming is completed, the insulated glass 20 and the outer frame 3 are installed in sequence, which can ensure the tight fit between the components and improve the integrity and sealing of the door.

[0065] The above-described process allows for the replacement of different types of insulated glass 20 according to varying usage environments, such as insulated glass 20 suitable for refrigeration or freezing environments, thereby meeting the specific needs of different users and improving product compatibility and adaptability. Simultaneously, it significantly increases production efficiency and reduces labor costs, facilitating large-scale production and application.

[0066] In some embodiments of this application, a clamping groove 23 is formed on the inner frame 2 of the door, and the clamping groove 23 is used to clamp the light strip 30.

[0067] In this embodiment, by providing a clamping groove 23 on the inner frame 2 of the door, a convenient and stable position is provided for the installation of the light strip 30, so that the light strip 30 can be firmly fixed on the inner frame 2 of the door, which facilitates the installation and removal of the light strip 30. At the same time, it is also conducive to the tight integration of the light strip 30 with the door body, improving the aesthetics and decoration of the door body.

[0068] refer to Figure 5 The clamping groove 23 is located between the mounting groove 5 and the end of the inner frame 2 of the door that is away from the outer frame 3 of the door. The light strip 30 is held against the outer glass 71 by the side wall of the mounting groove 5.

[0069] In this embodiment, the light strip 30 abuts against the outer glass 71 through the side wall of the mounting groove 5, so that the heat generated by the light strip 30 can be transferred to the outer glass 71 through the side wall of the mounting groove 5, which further improves the generation of condensation on the insulating glass 20.

[0070] In some embodiments, the light strip 30 is abutted against one end of the door frame 1. (See reference) Figure 4 The light strip 30 is attached to the first hook 11 of the door frame 1.

[0071] In this embodiment, by attaching the light strip 30 to the door frame 1, heat transfer is facilitated, allowing the heat generated by the light strip 30 during operation to be transferred to the door frame 1 in a timely manner, thereby further improving the effect of condensation on the door frame 1.

[0072] refer to Figure 7 The inner frame 2 of the door can include a first inner frame 21, one end of the first inner frame 21 is engaged with one end of the door frame 1, and the other end of the first inner frame 21 is provided with a first fastening part 8.

[0073] The inner frame 2 of the door may include a second inner frame 22, which is connected to the outer frame 3 of the door.

[0074] refer to Figure 5 , Figure 7 One end of the second inner frame 22 is engaged with the other end of the door frame 1, and the other end of the second inner frame 22 is provided with a second fastening part 9.

[0075] The first fastening part 8 and the second fastening part 9 are adapted to be connected to form a fastening structure. In the thickness direction of the hollow glass door body 100, the fastening structure is located between the inner glass 72 and the outer glass 71.

[0076] In this embodiment, the inner frame 2 of the door adopts a split structure. When the inner frame 2 of the door is partially damaged, only the damaged first inner frame 21 or second inner frame 22 needs to be replaced, which reduces maintenance costs and maintenance time and enhances the maintainability of the product.

[0077] Furthermore, the first inner frame 21 and the second inner frame 22 are connected by a snap-fit ​​structure, making the connection between the inner frame 2 and the outer frame 3 of the door more convenient, tighter and stronger, enhancing the overall structural stability of the door, and also facilitating installation and disassembly.

[0078] refer to Figure 6 The two ends of the door frame 1 are respectively provided with a first hook 11 and a second hook 12, and the two ends of the inner frame 2 are respectively provided with a first latching part 24 and a second latching part 25.

[0079] The first snap-fit ​​part 24 is adapted to snap-fit ​​with the first snap hook 11, and the second snap-fit ​​part 25 is adapted to snap-fit ​​with the second snap hook 12, so that the inner frame 2 of the door is connected to the door frame 1.

[0080] In this embodiment, the use of hooks and snap-fit ​​parts enables quick and stable snap-fit ​​between the door frame 1 and the inner door frame 2, improving installation efficiency and simplifying the installation process. This not only facilitates later maintenance and replacement but also ensures a tight fit between the inner door frame 2 and the door frame 1, thereby improving the overall structural strength and stability of the door.

[0081] The first latching part 24 is disposed on the first inner frame 21, and the second latching part 25 is disposed on the second inner frame 22.

[0082] In this embodiment, the first hook 11 and the second hook 12 are formed by bending the two ends of the L-shaped door frame 1 inwards respectively. This design not only simplifies the processing technology of the door frame 1 and reduces production costs, but also ensures the strength and rigidity of the first hook 11 and the second hook 12, ensuring the reliability of the connection between the inner door frame 2 and the door frame 1.

[0083] In some embodiments, the outer frame 3 of the door may include a support portion 31 and a fixing latch 32 connected to the support portion 31. The support portion 31 forms a side wall of the mounting groove 5 for abutting against the inner glass 72.

[0084] refer to Figure 5 , Figure 7 The inner frame 2 of the door is provided with a lock opening 26, and the fixing buckle 32 is adapted to be fastened in the lock opening 26 so that the inner frame 2 of the door is tightly connected to the outer frame 3 of the door.

[0085] In this embodiment, the fixed latch 32 is adapted to and latches with the lock opening 26 on the inner frame 2 of the door, so that the inner frame 2 of the door and the outer frame 3 of the door are tightly connected, which further improves the overall structural strength and sealing of the door and extends the service life of the insulated glass door 100.

[0086] Further reference Figure 7 The lock 26 has a first latching arm 261 and a second latching arm 262 that are arranged opposite to each other. The outer side of the first latching arm 261 is engaged with one end of the door frame 1, and the outer side of the second latching arm 262 forms part of the bottom wall of the mounting groove 5.

[0087] The aforementioned lock opening 26 not only fits tightly with the fixed latch 32 for connection, but the snap-fit ​​between the first latching arm 261 and the door frame 1 further strengthens the connection between the inner door frame 2 and the door frame 1, improving the reliability and stability of the connection. The outer side of the second latching arm 262 serves as part of the bottom wall of the mounting groove 5, providing support and positioning for the inner glass 72, ensuring the stability and installation accuracy of the inner glass 72 within the mounting groove 5. This also makes the internal structure of the door more compact and rational, improving the overall performance of the door.

[0088] refer to Figure 3 The insulated glass 20 also includes a support member 73, which is sandwiched between the inner glass 72 and the outer glass 71. A sealing layer 74 is provided on the side of the support member 73 near the end of the insulated glass 20.

[0089] In this embodiment, the support member 73 maintains the distance between the inner glass 72 and the outer glass 71, ensuring the stable performance of the heat insulation and sound insulation properties of the insulated glass 20. The sealing layer 74 enhances the sealing performance of the insulated glass 20, effectively preventing water vapor in the air from entering the interior of the insulated glass 20, avoiding fogging and condensation, extending the service life of the insulated glass 20, and also improving the thermal insulation performance of the door.

[0090] For example, the support member 73 can be an aluminum frame. Furthermore, in this embodiment, the inside of the aluminum frame can be a desiccant, which is used to absorb moisture inside the insulating glass 20, prevent condensation, and maintain a dry internal environment.

[0091] This utility model also provides a freezer, which includes a cabinet body and a cabinet door.

[0092] It is understood that the freezer in this embodiment can be either a freezer or a refrigerator, and there is no limitation on it.

[0093] Specifically, the cabinet door in this embodiment can be the hollow glass door 100 of this utility model, and its specific structure can be found in the hollow glass door 100 embodiment of this utility model and the accompanying drawings. Figures 1 to 8 The details of that record will not be repeated here.

[0094] In this embodiment, the freezer effectively prevents condensation on the door frame 1 by filling the receiving space 4 of the door frame 10 with foaming agent 6, replacing the original heating wire. Simultaneously, the foaming agent 6 does not directly contact the insulating glass 20, allowing the insulating glass 20 to be installed after foaming, and different types of insulating glass 20 can be used depending on the usage environment. This makes the insulating glass door 100 suitable for freezers with different needs.

[0095] Furthermore, the application of the aforementioned hollow glass door 100 to freezers can effectively improve the freezer's heat preservation performance, reduce cold air leakage, and lower energy consumption. At the same time, the aesthetics and durability of the hollow glass door 100 are also improved, enhancing the overall quality and market competitiveness of the freezer.

[0096] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0097] The above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
