[0032] See also Figure 1-3 The present application proposes a drawer-type refrigerator with a novel guide rail installation structure, comprising: an inner tank 1, a drawer box 2, a slide rail 3 and a reinforcing plate 4; a slide groove 101 is provided on the inner side wall of the inner tank 1, and the slide rail 3 is slidably connected to the slide groove 101; a first bending plate 401 is provided at the rear of the reinforcing plate 4, a second bending plate 402 is provided at the front of the reinforcing plate 4, and a third bending plate 403 is provided at the upper part of the reinforcing plate 4; Figure 4 As shown, a light switch 5 is provided on the rear side wall of the inner tank 1, the first bending plate 401 is used to trigger the light switch 5, the second bending plate 402 is fixedly connected to the drawer box 2, the third bending plate 403 is provided with a fixing hole 4031, and the slide rail 3 is fixedly connected to the fixing hole 4031 through a fixing column 301.

[0033] By opening a sliding groove 101 on the inner wall of the inner tank 1 and slidingly connecting it with the slide rail 3, and at the same time utilizing the bent plate structure on the reinforcing plate 4 to tightly connect the slide rail 3, the inner tank 1 and the drawer box 2 into one, the installation stability and accuracy of the slide rail 3 are significantly improved, the complexity and error during the installation process are reduced, and the smooth sliding of the drawer and the overall stability of the refrigerator are ensured.

[0034] Preferably, if Figure 4 As shown, a support frame may be provided below the sliding groove 101 , and the support frame provides support for the slide rail 3 , thereby further improving the stability of the connection between the slide rail 3 and the sliding groove 101 .

[0035] The design of the reinforcing plate 4 and its bent plate forms a stable supporting structure, which enhances the connection strength between the drawer box 2 and the inner liner 1 and prevents deformation or damage caused by the placement of heavy objects or frequent use; and through the fixed connection between the bent plate, the drawer box 2 and the slide rail 3, the installation process is simplified and the parts and steps required for installation are reduced; in addition, the design of the bent plate makes the connection between the various components more precise, reduces errors during the installation process, and ensures smooth sliding of the drawer.

[0036] The design of the first bent plate 401 triggering the light switch 5 realizes intelligent control of the lighting system. When the drawer is closed, the first bent plate 401 automatically triggers the light switch 5 to turn off the lighting, avoiding energy waste caused by the lighting still on after the drawer is closed, and achieving the effect of energy saving and environmental protection.

[0037] Those skilled in the art may refer to the existing light switch 5 for the specific circuit principle of the light switch 5. The circuit connection relationship of the light switch 5 is the existing technology and will not be described in detail in this application.

[0038] It is understandable that the fixing column 301 and the fixing hole 4031 can further strengthen the fixing structure by using interference fit, chemical materials (such as resin, glue, etc.) or hot melt fixing, and the present application does not make specific limitations here.

[0039] The refrigerator refrigeration system is common knowledge in the art, and this application does not limit it. Those skilled in the art can choose according to actual needs. Specifically, the following refrigeration system can be used: the refrigerant absorbs heat in the refrigerator in the evaporator and changes from liquid to gas; the gaseous refrigerant is compressed by the compressor into a high-temperature and high-pressure gas; the high-temperature and high-pressure gas refrigerant releases heat in the condenser and cools into a liquid; the liquid refrigerant is depressurized by the expansion valve and enters the evaporator again for the next cycle. Through this cycle, the refrigeration system can continuously absorb heat in the refrigerator and transfer it to the external environment, thereby maintaining a low temperature inside the refrigerator.

[0040] like Figure 5 As shown, in some embodiments, the drawer box 2 is provided with a fixing groove 201 , the size of the fixing groove 201 is matched with the size of the second bending plate 402 , and the second bending plate 402 is fixed in the fixing groove 201 .

[0041] By precisely fixing the second bent plate 402 in the fixing groove 201 of the drawer box 2, a stable connection point is formed, which significantly enhances the structural stability between the drawer box 2 and the reinforcing plate 4. This stable connection helps prevent the drawer from loosening due to uneven force or external force impact during use.

[0042] On the other hand, the fixing groove 201 is adapted to the size of the second bending plate 402, making the installation process more precise and simple. The installer can easily align and insert the second bending plate 402 into the fixing groove 201 without complicated adjustments and corrections, thereby improving the installation efficiency and quality.

[0043] The precise fixing groove 201 and the second bending plate 402 make the connection between the drawer box 2 and the reinforcing plate 4 more compact and smooth, reducing gaps and unevenness, which not only improves the overall aesthetics of the refrigerator, but also enhances the grade of the product.

[0044] like Figure 1 As shown, in some embodiments, the drawer box 2 also includes a door body 202, and the fixing groove 201 is arranged on the door body 202; the drawer box 2 is provided with a flange plate 203 on the side facing the reinforcing plate 4, and the flange plate 203 is fixedly connected to the third bending plate 403.

[0045] The connection between the fixing groove 201 and the flange plate 203 provides an additional connection point between the drawer box 2 and the reinforcing plate 4. The additional connection point can disperse the pressure of the drawer when it is subjected to external force or heavy objects, making the force more uniform, thereby reducing the possibility of single-point force and improving the overall load-bearing capacity.

[0046] The fixed connection between the flange plate 203 and the third bent plate 403 is usually achieved by bolts, welding or other fastening methods. These connection methods have high strength and stability, and can ensure a stable connection between the drawer box 2 and the reinforcement plate 4 to prevent loosening or falling off during use.

[0047] The flange plate 203 is usually designed to increase the thickness and strength of the local material. By connecting the flange plate 203 with the third bent plate 403, the reinforcing effect of the flange plate 203 can be fully utilized to improve the bending strength and rigidity of the drawer box 2 at the stressed part.

[0048] like Figure 1 , Figure 7 As shown, in some embodiments, a controller 6 is disposed on the drawer box 2 , a light source 7 is disposed in the controller 6 , and the light source 7 is electrically connected to the light switch 5 .

[0049] The light source 7 will light up only when the drawer box 2 is opened and lighting is needed, avoiding unnecessary lighting waste, helping to save energy and electricity, and at the same time, extending the service life of the light source 7 and reducing the frequency and cost of replacing the light source 7.

[0050] The controller 6 is usually designed as a detachable or replaceable module, which makes it easier to maintain and replace the light source 7; when the light source 7 fails or needs to be replaced, the user or maintenance personnel can easily remove the controller 6 and replace the light source 7 without having to disassemble the entire drawer box 2 on a large scale.

[0051] like Figure 7 As shown, in some embodiments, a light-transmitting hole is opened at the bottom of the controller 6, the light source 7 is arranged above the light-transmitting hole, and the controller 6 is provided with a plurality of snap-fit ​​parts 8 near the light-transmitting hole, and the snap-fit ​​parts 8 are snap-connected with the light source 7.

[0052] The buckle connection between the buckle 8 and the light source 7 simplifies the installation process, and the light source 7 can be quickly fixed to the controller 6 without using additional screws or tools. When the light source 7 needs to be replaced, it is only necessary to unfasten the buckle 8 to easily take out and replace the new light source 7, which greatly reduces maintenance costs and time.

[0053] like Figure 7 As shown, in some embodiments, the controller 6 is further provided with a plurality of limit plates 9 near the light-transmitting hole, and the light source 7 is fixed in the plurality of limit plates 9 .

[0054] The limiting plate 9 provides a precise installation position for the light source 7, ensures the alignment of the light source 7 with the light-transmitting hole, avoids displacement during the installation process, and thus enhances the stability of the light source 7; and when the drawer box 2 moves or is subjected to external force, the limiting plate 9 can effectively reduce the vibration of the light source 7, preventing it from being damaged or affecting the lighting effect due to looseness.

[0055] like Figure 6 As shown, in some embodiments, the inner tank 1 is provided with a mounting hole, and the side wall of the light switch 5 is provided with an elastic member 10 , and the light switch 5 is interference-fitted with the mounting hole through the elastic member 10 .

[0056] Since the interference fit is adopted, during installation, it is usually only necessary to push the light switch 5 into the installation hole until the elastic member 10 is deformed and stuck, without using additional fasteners such as screws and nuts, thereby simplifying the installation process.

[0057] like Figure 6 As shown, in some embodiments, the side wall of the light switch 5 is provided with two elastic members 10 , and the two elastic members 10 are respectively located at the top and the bottom of the light switch 5 .

[0058] The interference fit between the two elastic members 10 and the mounting holes forms a double locking mechanism, further improving the stability of the installation of the light switch 5. Even when the drawer box 2 is frequently opened and closed or subjected to external force impact, the light switch 5 can maintain a stable connection state.

[0059] like Figure 6 As shown, in some embodiments, a non-slip strip 11 is provided on a side of the elastic member 10 away from the light switch 5 .

[0060] The design of the anti-slip strip 11 increases the friction between the elastic member 10 and the inner wall of the mounting hole, making the light switch 5 more stable during installation and less likely to slip or fall off, thereby ensuring that the light switch 5 can maintain a stable connection state for a long time and is not easy to loosen even when subjected to external force.

[0061] The embodiments described above are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention, and should be included in the protection scope of the present invention.
