Description

Technical Field

[0001] The invention belongs to the technical field of refrigeration equipment, and in particular relates to a cabinet opening drainage structure of a horizontal refrigerator and the horizontal refrigerator. Background Art

[0002] Condensation water is easily formed on the sliding door of a horizontal glass sliding door freezer during the refrigeration process. The condensation water gathers at the cabinet opening. Therefore, a drainage structure needs to be set at the cabinet opening to drain the condensation water out of the freezer. There are two types of drainage outlets:

[0003] The first method is to set a drain hole at the corner of the refrigerator to drain the condensed water, such as Figure 1 As shown, on the one hand, the drain hole is small and the drainage volume is limited; on the other hand, due to the size of the drain hole, it is impossible to install a filter, and the condensed water is directly discharged into the drain pipe, which is easy to cause dirt and blockage and is not convenient for cleaning; on the other hand, the drain hole is exposed at the corner of the refrigerator cabinet and faces upward, which is not only unsightly but also easy to accumulate dust.

[0004] The second method is to set a drainage filter plug on the glass sliding door slideway that is squeezed out of the cabinet opening. This drainage filter structure can achieve drainage and filtering functions, but it has the following disadvantages:

[0005] like Figure 2 As shown, the drain filter plug is generally arranged on the slide of the extruded cabinet opening near the side panel of the injection molded cabinet opening. However, the drain filter plug is a certain distance away from the side panel. Therefore, when the glass sliding door slides toward the side panel, the condensed water on the portion L between the drain filter plug on the slide and the side panel cannot be discharged from the drain filter plug. The condensed water accumulates more in the portion L. Even under the thrust of the glass sliding door, the condensed water at the portion L will directly overflow into the cabinet body to form frost.

[0006] Since the drainage filter plug is set on the slide that squeezes out the cabinet opening, it is easy to cause uneven docking with the slide, which causes a sense of frustration when pushing and pulling the glass sliding door, affecting the customer experience and easily accumulating dust.

[0007] Since it is necessary to open a drain port on the slide of the extruded cabinet opening, the extruded cabinet opening is generally processed by an extrusion process. It is necessary to process the drain port on the slide after the slide is extruded and formed, which has many processing steps and complicated processes.

[0008] The scheme of setting drainage filter plug on the slideway will also make the sealing between the glass sliding door and the cabinet opening worse: Figure 3 , Figure 4 As shown, since the glass sliding door and the slide are in hard line contact, the sealing performance of the glass sliding door and the slide at the drainage filter plug is not good, and the air in the cabinet and the outside air are easy to flow at the drainage filter plug between the glass sliding door and the slide. Figure 3The airflow path at the contact point between the upper glass sliding door and the drain outlet is shown. Figure 4 The figure shows the airflow path at the contact point between the lower glass sliding door and the drain port. This method not only causes the air inside the refrigerator to be discharged outside the refrigerator, reducing the refrigerator's refrigeration efficiency, but also easily causes external moisture to enter the cabinet and form frost.

[0039] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] This embodiment provides a horizontal refrigerator, including a cabinet body, a cabinet opening is arranged on the top of the cabinet body, a slidable glass sliding door is arranged on the cabinet opening, and the glass sliding door cooperates with the cabinet opening to open and close the refrigerator. A slide is arranged on the cabinet opening, and the glass sliding door slides on the slide of the cabinet opening.

[0041] When the refrigerator is working, there is a temperature difference between the inside and outside of the refrigerator. When the temperature difference between the inside and outside of the glass sliding door is greater than the dew point, condensation water is easily generated on the glass sliding door. The condensation water will flow along the glass sliding door to the cabinet opening. Therefore, in order to prevent the condensation water from accumulating at the cabinet opening and flowing into the inside of the refrigerator, causing ice and frost inside the refrigerator, it is necessary to design a drainage structure on the cabinet opening to discharge the condensation water at the cabinet opening.

[0042] The present embodiment designs a drainage structure on the cabinet opening. The cabinet opening of the present embodiment includes a first extruded cabinet opening portion and a second injection molded cabinet opening portion connected to each other, wherein the injection molded cabinet opening portion is an injection molded profile formed by an injection molding process, and the extruded cabinet opening portion is an extruded profile formed by an extrusion process. A slideway for bearing a glass sliding door is provided on the first extruded cabinet opening portion, and the glass sliding door slides along the slideway. The second injection molded cabinet opening portion includes a side panel located above the slideway. When the glass sliding door closes the cabinet opening, the side panel contacts the glass sliding door to close the cabinet opening. The end of the slideway is connected to the side panel, and the joint formed by the slideway and the side panel is outside the portion of the slideway bearing the glass sliding door. The slideway portion bearing the glass sliding door has no joints, is flat, has good sealing, and does not cause a sense of frustration or wear due to the joints when the glass sliding door is pushed and pulled. In addition, the joints are in a hidden position and are not easy to accumulate dust. In this embodiment, a slide drain outlet is provided on the side panel at a position corresponding to the slide, and the condensed water on the slide can be discharged through the slide drain outlet. When the glass sliding door slides, the condensed water on the slide can be completely discharged from the slide drain outlet under the thrust of the glass sliding door, and there will be no water accumulation.

[0043] When the glass sliding door contacts the side panel, the glass sliding door is used to isolate the slide drain outlet from the space inside the refrigerator. This embodiment can enhance the sealing between the glass sliding door and the cabinet opening at the slide drain outlet, prevent the air inside the cabinet and the outside air from flowing at the slide drain outlet of the side panel, improve the refrigeration efficiency of the refrigerator, and reduce frosting.

[0044] Specifically, such as Figure 5 As shown, in this embodiment, a cabinet opening is arranged on the refrigerator cabinet body 1, and the cabinet opening includes a front extruded cabinet opening part 4, a left injection molded cabinet opening part 2, a rear extruded cabinet opening part 5 and a right injection molded cabinet opening part 3 which are connected in sequence, and an upper glass sliding door 6 and a lower glass sliding door 7 are slidably arranged on the cabinet opening.

[0045] An upper slideway 451 for carrying the upper glass sliding door 6 and a lower slideway 452 for carrying the lower glass sliding door 7 are arranged on the front extrusion cabinet opening 4 and the rear extrusion cabinet opening 5, and the ends of the upper slideway 451 and the lower slideway 452 are respectively connected to the left injection cabinet opening 2 and the right injection cabinet opening 3. The left injection cabinet opening 2 includes a side panel 23 located above the upper slideway 451 and the lower slideway 452, and the side panel 23 is connected with the slideway to form a joint, and the formed joints are all outside the part of the slideway bearing the glass sliding door, and there is no joint on the part of the slideway bearing the glass sliding door, so that the glass sliding door can slide freely on the slideway.

[0046] When the glass sliding door closes the cabinet opening, the upper glass sliding door 6 contacts the side panel 23 of the right injection cabinet opening 3, and the lower glass sliding door 7 contacts the side panel 23 of the left injection cabinet opening 2. An upper slideway drain port 2311 is provided at a portion of the side panel 23 corresponding to the upper slideway 451, and a lower slideway drain port 2321 is provided at a portion of the side panel 23 corresponding to the lower slideway 452, and the height of the upper slideway drain port 2311 is higher than that of the lower slideway drain port 2321.

[0047] like Figure 6 , 15 As shown, the front extruded cabinet opening is taken as an example for explanation, and the structure of the rear extruded cabinet opening is similar to that of the front cabinet opening.

[0048] The front extrusion cabinet opening 4 includes an upper slide 451 and a lower slide 452 .

[0049] The upper slide 451 includes a horizontal slide located below the upper glass sliding door 6 for supporting the upper glass sliding door 6 and a vertical slide located above the horizontal slide and perpendicular to the horizontal slide. The horizontal slide is used to support the lower surface of the upper glass sliding door 6, and the upper slide drain 2311 is located above the horizontal slide. The vertical slide of the front extrusion cabinet opening 4 is used to limit the front side of the upper glass sliding door 6, and the vertical slide of the rear extrusion cabinet opening 5 is used to limit the rear side of the upper glass sliding door 6. In order to increase the smoothness of sliding, a slide rail is set on the horizontal slide. In order to improve the wear resistance of the upper glass sliding door 6, a slide bar 8 matching the slide rail is set on the lower surface of the upper glass sliding door 6. The slide bar 8 is preferably made of POM material. The lower slide 452 includes a horizontal slide located below the lower glass sliding door 7 for supporting the lower glass sliding door 7 and a vertical slide located above the horizontal slide and perpendicular to the horizontal slide. The horizontal slide is used to support the lower surface of the lower glass sliding door 7. The lower slide drain port 2321 is located above the horizontal slide. The vertical slide of the front extrusion cabinet opening 4 is used to limit the front side of the lower glass sliding door 7, and the vertical slide of the rear extrusion cabinet opening 5 is used to limit the rear side of the lower glass sliding door 7. In order to improve the wear resistance of the upper glass sliding door 6, as shown in FIG. Figure 7As shown, a slide bar 8 cooperating with the slide rail is provided on the lower surface of the lower glass sliding door 7, and the slide bar 8 is preferably made of POM material.

[0050] The upper slideway 451 is connected to the lower slideway 452 , that is, the horizontal slideway of the upper slideway 451 is connected to the vertical slideway of the lower slideway 452 .

[0051] like Fig.12 , 13 As shown in Figure 15, an appearance panel 453 is provided on the top of the extruded cabinet opening to form the appearance shape of the cabinet opening. The appearance panel of this embodiment includes a top panel 4531 located on the top surface of the cabinet body and a side panel 4532 located on the outer side of the cabinet body. The top panel 4531 is connected to the side panel 4532.

[0052] The exterior panel 453 is connected to the upper slideway 451 , and the top panel 4531 of the exterior panel 453 is connected to the vertical slideway of the upper slideway 451 .

[0053] Since the extruded profile is formed by an extrusion process, it is impossible to set a rich appearance on the extruded cabinet opening. In order to increase the richness and diversity of the cabinet opening, the present embodiment is provided with a modeling panel 236 on the injection molded cabinet opening, and the modeling panel 236 covers part of the appearance panel 453. Since the injection molded cabinet opening is formed by an injection molding process, a rich shape can be formed on the injection molded cabinet opening, and thus, a rich shape can also be formed on the modeling panel 236. By covering part of the appearance panel 453 of the extruded cabinet opening with the modeling panel 236, the richness and diversity of the overall shape of the cabinet opening can be increased.

[0054] like Fig.12 , 13 As shown in Figures 14, the styling panel 236 is located at the end of the left injection molding cabinet opening 2, and the styling panel 236 is at a certain angle to the left injection molding cabinet opening 2. Preferably, the styling panel 236 is perpendicular to the side panel 23 of the left injection molding cabinet opening 2.

[0055] The styling panel 236 includes a top panel 2361 and a side panel 2362 . The top panel 2361 of the styling panel 236 partially covers the top panel 4531 of the exterior panel 453 , and the side panel 2362 of the styling panel 236 partially covers the side panel 4532 of the exterior panel 453 .

[0056] In order to match the shape of the refrigerator body 1 , the corner formed by the molding panel 236 and the injection molding cabinet opening has an arc segment 2363 that matches the refrigerator body 1 . Specifically, the arc segment 2363 is located on the side panel 2362 .

[0057] like Fig.13As shown, the covering width D of the modeling panel 236 and the appearance panel 453 is at least 4 mm. After the injection molded cabinet mouth and the extruded cabinet mouth are assembled, they are assembled with the box shell and the inner liner of the cabinet body 1, and foaming is performed after assembly. Due to the expansion force inside the foaming material, the injection molded cabinet mouth and the extruded cabinet mouth may be displaced by 1-2 mm. Since the covering width D of the modeling panel 236 and the appearance panel 453 of this embodiment exceeds 4 mm, even if the injection molded cabinet mouth and the extruded cabinet mouth are displaced, no flash seam will appear between the injection molded cabinet mouth and the extruded cabinet mouth.

[0058] In order to improve the stability of the injection molding cabinet and the extrusion cabinet after assembly, Fig.14 As shown, a first bearing part 233 for bearing the two ends of the upper slide 451 and the lower slide 452 is provided on the injection molding cabinet opening, and the first bearing part 233 is located below the upper slide 451 and the lower slide 452 and contacts the upper slide 451 and the lower slide 452, and supports the upper slide 451 and the lower slide 452. Preferably, a positioning structure is provided on the contact surface between the first bearing part 233 and the upper slide 451 and the lower slide 452, and a positioning structure is provided on the contact surface between the upper slide 451 and the lower slide 452 and the first bearing part 233, and the positioning structure can be a positioning rib 234. Of course, the positioning structure can also be provided only on the upper slide 451 and the lower slide 452, or the positioning structure can be provided on the first bearing part, the upper slide 451 and the lower slide 452.

[0059] like Figure 6 As shown, the left injection molded cabinet opening 2 includes a side panel 23 located above the upper slide 451 and the lower slide 452. The side panel 23 is vertically arranged with the upper slide 451 and the lower slide 452. The side panel 23 is connected with the upper slide 451 and the lower slide 452. The joint formed by the side panel 23 and the slide is located outside the part of the slide that supports the glass sliding door, which can avoid the sense of frustration when the glass sliding door slides and improve the sealing of the slide. The side panel 23 contacts the left side surface of the lower glass sliding door 7. The side panel 23 has a plane that contacts the left side surface of the lower glass sliding door 7, as shown in FIG. Figure 7 As shown, the left side of the lower glass sliding door 7 is a plane formed by the soft sealing strip 9. The side panel 23 is provided with an upper slideway drain port 2311 and a lower slideway drain port 2321. The upper slideway drain port 2311 is located above the horizontal slideway of the upper slideway 451, and the lower slideway drain port 2321 is located above the horizontal slideway of the lower slideway 452.

[0060] When the lower glass sliding door 7 contacts the side panel 23 of the left injection molded cabinet opening 2, the lower glass sliding door 7 is used to isolate the upper slide drain outlet 2311 and the lower slide drain outlet 2321 of the side panel 23 of the left injection molded cabinet opening 2 from the space inside the refrigerator.

[0061] When the lower glass sliding door 7 closes the cabinet opening, the side surface of the lower glass sliding door 7 contacts the side panel 23 of the left injection molded cabinet opening 2 to form a seal, the slide bar 8 of the lower glass sliding door 7 contacts the horizontal slide of the lower slide 452 to form a seal, and the slide bar 8 of the lower glass sliding door 7 contacts the side panel 23 to form a seal. At this time, the lower slide drain 2321 is located between the position corresponding to the slide bar 8 on the side panel 23 and the vertical slide. When the lower glass sliding door 7 closes the cabinet opening, the lower slide drain 2321 can be completely isolated from the space inside the refrigerator, and at the same time, the upper slide drain 2311 can also be isolated from the space inside the refrigerator. In addition, a soft sealing strip is provided on the side of the lower glass sliding door 7, and the sealing strip 9 can be completely in contact with the side panel 23, so that the sealing performance between the lower glass sliding door 7 and the left injection molded cabinet opening 2 is greatly improved, and the air inside the cabinet and the outside air are prevented from flowing in the slideway drain port of the side panel, thereby improving the refrigeration efficiency of the refrigerator and reducing frosting. However, this method limits the position of the lower slideway drain port 2321, making the drainage area of ​​the lower slideway drain port 2321 smaller.

[0062] In order not to limit the lower slideway drain port 2321 to the position between the side plate 23 corresponding to the slide bar 8 and the vertical slideway, and to further improve the sealing effect, as shown in FIG. Figure 6 As shown, in this embodiment, a bearing plane 231 connected to the horizontal slideway of the lower slideway 452 is provided on the side panel 23 of the left injection molded cabinet opening 2. When the lower glass sliding door 7 contacts the side panel 23 of the left injection molded cabinet opening 2, the lower surface of the lower glass sliding door 7 contacts the bearing plane 231 and the horizontal slideway to form a seal. At this time, due to the existence of the bearing plane 231, the portion corresponding to the slide bar 8 on the side panel 23 can also be provided as a lower slideway drain port 2321 to increase the drainage area of ​​the lower slideway drain port 2321.

[0063] like Figure 7 As shown, the sealing strip 9 on the lower glass sliding door 7 includes a portion located on the side of the lower glass sliding door 7 and a portion located below the lower glass sliding door 7. The sealing strip 9 contacts the side panel 23 and the bearing plane 231 of the left injection molding cabinet opening 2. Specifically, the sealing strip located on the side of the lower glass sliding door 7 contacts the side panel 23, and the sealing strip located below the lower glass sliding door 7 contacts the bearing plane 231. The sliding strip 8 is connected to the end of the sealing strip 9.

[0064] In this embodiment, Figure 8 , 10As shown, the lower slide drain outlet 2321 is located above the horizontal slide of the lower slide 452. When the lower glass sliding door 7 contacts the side panel 23, the slide bar 8 contacts the horizontal slide of the lower slide 452, the sealing strip 9 contacts the side panel 23 and the load-bearing plane 231, and the slide bar 8 is connected to the end of the sealing strip 9, which can completely isolate the lower slide drain outlet 2321 from the space inside the cabinet, thereby, the upper slide drain outlet 2311 is also isolated from the space inside the cabinet. Specifically, when the lower glass sliding door 7 contacts the side panel 23, the sealing strip 9 contacts and seals with the side panel 23 and the load-bearing plane 231 of the left injection-molded cabinet opening 2; the slide bar 8 and the sealing strip 9 are in close contact at the connection to form a seal; the slide bar 8 is tightly fitted on the horizontal slide of the lower slide 452 through the gravity of the lower glass sliding door 7 to form a seal. As shown Fig.10 As shown, in this embodiment, when the left side of the lower glass sliding door 7 contacts the side plate 23 of the left injection molded cabinet opening 2, the lower glass sliding door 7 can completely isolate the upper slideway drain port 2311 and the lower slideway drain port 2321 from the space inside the refrigerator, and isolate the upper slideway drain port 2311 and the lower slideway drain port 2321 outside the refrigerator. The air inside and outside the cabinet will not move at the slideway drain port, thereby ensuring the sealing of the cabinet.

[0065] The assembly method of the right injection molded cabinet opening 3 and the front extruded cabinet opening 4 is similar to the assembly method of the left injection molded cabinet opening 2 and the front extruded cabinet opening 4, and will not be repeated here.

[0066] In this embodiment, when the upper glass sliding door 6 contacts the side panel 23 of the right injection molded cabinet opening 3, the upper glass sliding door 6 is used to seal the upper slideway drain outlet 2311 and the lower slideway drain outlet 2321 of the side panel 23 of the right injection molded cabinet opening 3 in the refrigerator. A soft sealing strip 9 is provided on the side of the upper glass sliding door 6. When the glass sliding door closes the cabinet opening, the soft sealing strip 9 on the side of the upper glass sliding door 6 contacts the side panel 23. The part where the soft sealing strip 9 contacts the side panel 23 is located above the upper slideway drain outlet 2311 and the lower slideway drain outlet 2321. Therefore, the upper glass sliding door 6 of this embodiment can seal the upper slideway drain outlet 2311 and the lower slideway drain outlet 2321 of the side panel 23 of the right injection molded cabinet opening 3 in the refrigerator. In this embodiment, the sealing performance of the cabinet opening at the slide drain outlet is greatly improved, which prevents the air inside the cabinet and the external air from flowing at the slide drain outlet of the side panel, improves the refrigeration efficiency of the refrigerator, and reduces frosting.

[0067] like Fig.11As shown, when the upper glass sliding door 6 contacts the side plate 23 of the right injection molded cabinet opening 3, the right side of the upper glass sliding door 7 completely seals the upper slide drain port 2311 and the lower slide drain port 2321 in the refrigerator. The air inside and outside the cabinet will not flow at the upper slide drain port 2311 and the lower slide drain port 2321, ensuring the sealing performance.

[0068] Therefore, when the lower glass sliding door 7 and the upper glass sliding door 6 close the cabinet opening, the condensed water on the lower slide 452 can be discharged through the lower slide drain outlet 2321 on the side panel 23 of the left injection molded cabinet opening part 2 and the lower slide drain outlet 2321 on the side panel 23 of the right injection molded cabinet opening part 3; the condensed water on the upper slide 451 can be discharged through the upper slide drain outlet 2321 on the side panel 23 of the left injection molded cabinet opening part 2 and the upper slide drain outlet 2321 on the side panel 23 of the right injection molded cabinet opening part 3. During the sliding process of the lower glass sliding door 7 toward the left injection molded cabinet opening 2, the condensed water on the lower slide 452 can be discharged through the lower slide drain port 2321 on the side panel 23 of the left injection molded cabinet opening 2; during the sliding process of the lower glass sliding door 7 toward the right injection molded cabinet opening 3, the condensed water on the lower slide 452 can be discharged through the lower slide drain port 2321 on the side panel 23 of the right injection molded cabinet opening 3; during the sliding process of the upper glass sliding door 6 toward the left injection molded cabinet opening 2, the condensed water on the upper slide 451 can be discharged through the upper slide drain port 2311 on the side panel 23 of the left injection molded cabinet opening 2; during the sliding process of the upper glass sliding door 6 toward the right injection molded cabinet opening 3, the condensed water on the upper slide 451 can be discharged through the upper slide drain port 2311 on the side panel 23 of the right injection molded cabinet opening 2.

[0069] In this embodiment, since the height of the rear extrusion cabinet opening 5 is higher than the height of the front extrusion cabinet opening 4, the condensed water on the glass sliding door is generally accumulated on the front extrusion cabinet opening 4. Therefore, in this embodiment, it is only necessary to set a drain outlet at the position corresponding to the left injection molding cabinet opening 2 and the right injection molding cabinet opening 3 and the front extrusion cabinet opening 4 (that is, the side plate 23 at the front end of the left injection molding cabinet opening 2 and the right injection molding cabinet opening 3). Of course, in order to avoid the accumulation of condensed water at the rear extrusion cabinet opening 5 and ensure the drainage of the rear extrusion cabinet opening 5, a drain outlet can also be set at the position corresponding to the left injection molding cabinet opening 2 and the right injection molding cabinet opening 3 and the rear extrusion cabinet opening 5 (that is, the side plate at the rear end of the left injection molding cabinet opening 2 and the right injection molding cabinet opening 3). The setting form of the drain outlet at the rear end of the left injection molding cabinet opening 2 and the right injection molding cabinet opening 3 is the same as the setting form of the front end of the left injection molding cabinet opening 2 and the right injection molding cabinet opening 3, which will not be repeated here. The form of arranging drainage holes at the front and rear ends of the left injection molding cabinet opening 2 and the right injection molding cabinet opening 3 is particularly suitable for the case where the front extrusion cabinet opening and the rear extrusion cabinet opening have the same height.

[0070] Of course, the present invention can also only set the lower slide drain outlet 2321 on the side panel of the left injection molding cabinet mouth part 2, and only set the upper slide drain outlet 2321 on the side panel of the right injection molding cabinet mouth part 3. In this scheme, the condensed water on the lower slide 452 can only be discharged through the lower slide drain outlet 2321 on the side panel 23 of the left injection molding cabinet mouth part 2; the condensed water on the upper slide 451 can only be discharged through the upper slide drain outlet 2311 on the side panel 23 of the right injection molding cabinet mouth part 3. The drainage effect of this scheme is not as good as that of the present embodiment, but it is still within the protection scope of the present invention.

[0071] In order to ensure the drainage effect, preferably, the upper slide drain outlet 2311 and the lower slide drain outlet 2321 both have a filtering function, which can filter out debris in the condensed water passing through the drain outlet to prevent the debris from clogging the drainage structure, resulting in poor drainage or no drainage.

[0072] In order to facilitate the formation of drainage outlets, such as Figure 6 , 8 As shown in FIGS. 9 and 10, the upper slideway drain outlet 2311 and the lower slideway drain outlet 2321 of this embodiment are several notches opened at the bottom of the side plate 23. The diameter of the notches is very small and the notches are used for drainage and filtration. The notches can be directly formed during the injection molding process of the left injection molding cabinet opening 2 and the right injection molding cabinet opening 3, without the need for further processing after the side plate processing is completed. The notches can be formed in one step, which greatly simplifies the processing technology of the drain outlet.

[0073] The drain outlets of the slide of the drainage structure of this embodiment are all outside the part of the slide that supports the glass sliding door. There is no drain outlet on the part of the slide that supports the glass sliding door. Therefore, on the one hand, the glass sliding door can slide freely on the slide, avoiding the sense of frustration caused by the existence of the drain outlet when the glass sliding door slides. On the other hand, the sealing of the contact between the glass sliding door and the slide can be guaranteed.

[0074] In this embodiment, a drainage part is provided on the inner side of the side plate 23 for receiving condensed water discharged from the upper slide drain port 2311 and the lower slide drain port 2321. A water outlet is provided at the bottom of the drainage part, and a drainage pipe (not shown in the figure) is connected to the water outlet. The condensed water received by the drainage part is discharged through the drainage pipe.

[0075] Specifically, Fig. 9As shown, the drainage part includes a drainage funnel 2331 located below the drainage outlet 2321 of the lower slide and a guide part 2341 located below the drainage outlet 2311 of the upper slide. The guide part 2341 is used to guide the condensed water discharged from the drainage outlet of the upper slide to the drainage funnel 2331. The drainage funnel 2331 receives the condensed water directly flowing down from the drainage outlet 2321 of the lower slide on the one hand, and receives the condensed water flowing down from the drainage outlet 2311 of the upper slide guided by the guide part 2341 on the other hand. The drainage funnel 2331 has a certain water storage capacity, which can avoid the problem of poor drainage when there is a large amount of condensed water on the slide. This embodiment adopts a combination of the drainage funnel and the guide part, so that the drainage part is of appropriate size, occupies less space and can ensure smooth drainage.

[0076] For the convenience of processing, the drainage funnel 2331 and the guide part 2341 are integrally formed.

[0077] The left injection molding cabinet opening 2 and the right injection molding cabinet opening 3 are provided with a mounting structure for mounting the drainage part. The mounting structure is a card slot 2351 located on the left injection molding cabinet opening 2 and the right injection molding cabinet opening 3, and the top end of the drainage part is card-mounted in the card slot 2351.

[0078] Of course, the drainage part may also include a drainage funnel located below the lower slide drain outlet 2321 and the upper slide drain outlet 2311. The drainage funnel of this solution is larger in volume and has a stronger water storage capacity, which can avoid the problem of poor drainage when there is a large amount of condensed water on the slide, but it takes up more space.

[0079] The drainage structure of the horizontal refrigerator opening in this embodiment can not only ensure a good drainage effect, but also ensure the sealing between the glass sliding door and the refrigerator opening when the cabinet opening is closed, simplify the processing procedures, and improve the smoothness of the glass door sliding experience.
