Description

Technical Field

[0001] This utility model relates to the field of refrigerator technology, and in particular to a refrigerator vertical beam assembly for preventing condensation in a double-door refrigerator. Background Technology

[0002] Condensation on the exterior of refrigerators is a major concern for consumers. The temperature inside the refrigerator is much lower than the outside temperature. The cold air inside diffuses outwards through the insulation layer and door seals, resulting in lower surface temperatures on the refrigerator body and doors. When this cold air encounters hot, humid air, condensation forms on the refrigerator's exterior. Typically, a heater is installed inside the frame to resolve this issue.

[0003] Existing heating methods mostly use heating wires, which generate heat by passing an electric current through a wire-like metal material. However, heating wires have a relatively small heating area, a slow heating speed, and require a longer time to reach the desired temperature, resulting in relatively low efficiency. Furthermore, heating uniformity is lacking, easily leading to localized high temperatures and poor heating performance. Long-term use also reduces durability. In addition, the heating wires are secured with flame-retardant tape, which may experience decreased adhesion and aging after prolonged use. Replacement can be troublesome, as tape residue may remain on the device surface, requiring careful cleaning. Therefore, this invention provides a refrigerator vertical beam assembly for preventing condensation in a double-door refrigerator. Utility Model Content

[0004] The purpose of this invention is to provide a refrigerator vertical beam assembly for preventing condensation in a double-door refrigerator, thereby solving the aforementioned problems.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model discloses a refrigerator vertical beam assembly for preventing condensation in a double-door refrigerator. It includes an upper central beam and a lower central beam located in the middle of the double-door refrigerator. Both the upper and lower central beams include mounting grooves. An electric heating element and a flame-retardant cloth are sequentially arranged from the inside to the outside of the mounting groove. A sealing plate is provided between the flame-retardant cloth and the left and right side walls of the mounting groove. Spring clips are symmetrically arranged on the left and right inner side walls of the mounting groove at the upper and lower positions, pressing against the flame-retardant cloth. A matching cover plate is slidably arranged on the outer side wall of the mounting groove away from the flame-retardant cloth. A top plate is provided on the top of the mounting groove and the cover plate.

[0007] Furthermore, the mounting groove includes a mounting groove body, the bottom of which is integrally formed with a base plate, and symmetrically distributed limiting slides are integrally formed on the front ends of the left and right side walls of the mounting groove body; positioning components are symmetrically distributed vertically on the middle inner side wall of the mounting groove body, the positioning components include symmetrically distributed positioning posts, and the electric heating element has positioning holes that match the positioning posts; and several snap-fit ​​holes are provided on the left and right side walls of the mounting groove body on the side away from the limiting slides.

[0008] Furthermore, the left and right limiting sliders extend in the direction of the opposite surfaces.

[0009] Furthermore, the sealing plate includes a sealing plate body, and a plurality of snap-fit ​​blocks matching the snap-fit ​​holes are provided at one end of the sealing plate body that contacts the mounting groove body.

[0010] Furthermore, the cover plate includes a cover plate body, on which a limiting groove is integrally formed to cooperate with the limiting slide strip.

[0011] Furthermore, the spring clip includes an operating lever located in the middle position, with pressure rods symmetrically arranged at both ends of the operating lever, and a torsion spring at the other end of the pressure rod, the other end of the torsion spring being fixedly connected to the left and right inner sidewalls of the mounting groove.

[0012] Furthermore, the angle between the operating lever and the pressure lever is an obtuse angle.

[0013] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0014] This utility model double-door refrigerator uses an electric heating element for its vertical beam assembly to prevent condensation. Compared to heating wire, it has better stability and durability, a larger heating surface area, and can quickly and evenly transfer heat to the object being heated. This results in significant efficiency, reduces the likelihood of hot spots, and provides higher heating efficiency. It can also more effectively utilize energy and save energy, making it suitable for scenarios requiring rapid heating.

[0015] Flame-retardant fabric has good stability and will not become sticky like tape during long-term use. In terms of maintenance, if the flame-retardant fabric is damaged, it is relatively easy to replace. Simply release the spring clips and sealing plates that are holding it in place, and then install a new flame-retardant fabric.

[0028] like Figure 1-5 As shown, a refrigerator vertical beam assembly for preventing condensation in a double-door refrigerator includes an upper middle beam 1 and a lower middle beam 2 located in the middle of the double-door refrigerator. The structure of both the upper middle beam 1 and the lower middle beam 2 includes a mounting groove 3. An electric heating element 6 and a flame-retardant cloth 7 are installed sequentially from the inside to the outside in the mounting groove 3.

[0029] Electric heating elements 6 are not limited to copper-nickel alloys, aluminum, copper, carbon steel sheets, stainless steel, ceramics, polymer materials, etc. Compared with heating wires, they have better stability and durability, a larger heating surface area, and can quickly and evenly transfer heat to the object being heated. They are highly efficient, less prone to hot spots, and have relatively higher heating efficiency. They can utilize energy more effectively and save energy, making them suitable for scenarios requiring rapid heating.

[0030] The flame-retardant principle of flame-retardant cloth 7 is mainly due to the flame-retardant properties of the fiber itself. For example, when flame-retardant cloth made of aramid fiber comes into contact with a flame, the fiber will carbonize, forming a heat-insulating and oxygen-barrier protective layer, thereby inhibiting the spread of flames. In addition, flame-retardant cloth 7 has high strength and can withstand a certain amount of external force. In the electrical field, when electrical equipment needs to be protected, flame-retardant cloth can serve as a protective layer to resist damage to the equipment caused by some external factors (such as collisions, friction, etc.). Finally, flame-retardant cloth 7 has relatively good air permeability. Flame-retardant cloth can ensure ventilation and air permeability of the equipment to a certain extent, avoid excessive heat accumulation, and at the same time play a flame-retardant role. When applied to the anti-condensation design of this application, it can improve heating efficiency, thereby ensuring the efficiency and quality of anti-condensation.

[0031] A sealing plate 8 is installed between the flame-retardant cloth 7 and the left and right side walls of the mounting groove 3 to fix and seal the gap between them. Spring clips 9 are symmetrically installed at the top and bottom positions on the left and right inner side walls of the mounting groove 3. These spring clips 9 press against the flame-retardant cloth 7 to fix it in place. A matching cover plate 4 is slidably installed on the outer side wall of the mounting groove 3 away from the flame-retardant cloth 7. A top plate 5 is installed on the top of the mounting groove 3 and the cover plate 4. This design facilitates disassembly and installation. Disassembly is quick and easy; simply remove the top plate 5 and slide out the cover plate 4.

[0032] The mounting groove 3 includes a mounting groove body 301, with a base plate 305 integrally formed at the bottom. Symmetrically distributed limiting slide bars 302 are integrally formed on the front ends of the left and right side walls of the mounting groove body 301. The left and right limiting slide bars 302 extend towards their opposite faces. The cover plate 4 includes a cover plate body 401, with a limiting slide groove 402 integrally formed on the cover plate body 401 that cooperates with the limiting slide bars 302. The movement of the limiting slide groove 402 on the limiting slide bar 302 enables quick installation and removal.

[0033] Positioning components are symmetrically distributed on the inner side wall of the mounting groove body 301. The positioning components include positioning posts 303 symmetrically distributed on the left and right. The electric heating element 6 is provided with positioning holes that match the positioning posts 303, so as to facilitate quick installation of the electric heating element 6 and play the role of positioning and installation.

[0034] The mounting groove body 301 has several snap-fit ​​holes 304 on its left and right sidewalls away from the limiting slide bar 302. The sealing plate 8 includes a sealing plate body 801. Several snap-fit ​​blocks 802 that match the snap-fit ​​holes 304 are installed on the end of the sealing plate body 801 that contacts the mounting groove body 301. The snap-fit ​​blocks 802 are snapped into the snap-fit ​​holes 304 to achieve the compression installation of the flame-retardant cloth 7, thereby improving the efficiency of installation and disassembly.

[0035] The spring clip 9 includes an operating lever 903 located in the middle. Two pressure rods 902 are symmetrically mounted on both ends of the operating lever 903. A torsion spring 901 is mounted on the other end of each pressure rod 902, and the other end of the torsion spring 901 is fixedly connected to the left and right inner sidewalls of the mounting groove 3. The angle between the operating lever 903 and the pressure rod 902 is obtuse, facilitating the lifting of the operating lever 903. In use, lifting the operating lever 903 releases the braking of the flame-retardant sheet 7, facilitating the disassembly of the flame-retardant sheet 7 and the electric heating element 6. Afterward, releasing the operating lever 903 allows it to reset under the elastic force of the torsion spring 901, compressing the flame-retardant sheet 7 and achieving braking.

[0036] The installation process of this utility model is as follows:

[0037] First, lift the operating lever 903 and insert the positioning hole on the electric heating element 6 into the positioning post 303 on the mounting groove 3; then, the flame retardant sheet 7 is pressed onto the electric heating element 6, and the operating lever 903 is released. Under the elastic force of the torsion spring 901, it resets, and the spring clip 9 presses the upper and lower ends of the flame retardant sheet 7; then, the snap-fit ​​block 802 on the sealing plate 8 snaps into the snap-fit ​​hole 304 to realize the compression installation of the flame retardant cloth 7; finally, the limiting slide groove 402 moves from top to bottom on the limiting slide bar 302 until it reaches the bottom plate 305, and the top plate 5 seals the mounting groove 3 and the cover plate 4 together.

[0038] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
