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 existing drainage structures:

[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 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 slideway near the side panel of the cabinet opening. However, the drain filter plug is at a certain distance 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 slideway and the side panel cannot be discharged from the drain filter plug. The condensed water accumulates more at 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 to form frost.

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

[0007] 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 3 The 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. Summary of the invention

[0035] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] 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.

[0037] 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.

[0038] This embodiment designs the drainage structure on the cabinet opening.

[0039] like 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 extrusion cabinet opening portion 4, a left injection cabinet opening portion 2, a rear extrusion cabinet opening portion 5 and a right injection cabinet opening portion 3 which are connected in sequence. The extrusion cabinet opening portion is an extruded profile formed by an extrusion process, and the injection cabinet opening portion is an injection molded profile formed by an injection molding process.

[0040] A slideway for supporting a glass sliding door is provided on the extrusion cabinet opening, and the glass sliding door slides along the slideway. An upper glass sliding door 6 and a lower glass sliding door 7 are slidably provided on the cabinet opening.

[0041] 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 provided on the front extrusion cabinet opening 4 and the rear extrusion cabinet opening 5, and the two 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 right injection cabinet opening 3 includes an upper side plate 31 located above the upper slideway 451 and a lower side plate 32 located above the lower slideway 452, and a bearing plate 33 is provided between the upper side plate 31 and the lower side plate 32, and the side surface of the upper glass sliding door 6 contacts the upper side plate 31, and the lower surface of the upper glass sliding door 6 contacts the bearing plate 33. The upper side panel 31 is connected with the upper slide 451 to form a seam, and the formed seam is outside the position where the upper slide 451 supports the upper glass sliding door 6. The lower side panel 32 is connected with the lower slide 452 to form a seam, and the formed seam is outside the position where the lower slide 452 supports the lower glass sliding door 7. There is no seam on the position where the slide supports the glass sliding door. Therefore, the glass sliding door can slide freely on the slide and the sealing of the contact between the glass sliding door and the slide can be guaranteed.

[0042] like Figure 6 , 12 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.

[0043] The front extrusion cabinet opening 4 includes an upper slide 451 and a lower slide 452 .

[0044] The upper slide 451 includes a horizontal slide located below the upper glass sliding door 6 for carrying 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 carry the lower surface of the upper glass sliding door 6. 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 arranged on the horizontal slide. In order to improve the wear resistance of the upper glass sliding door 6, a slide bar cooperating with the slide rail is arranged on the lower surface of the upper glass sliding door 6. The slide bar is preferably made of POM material.

[0045] The lower slideway 452 includes a horizontal slideway located below the lower glass sliding door 7 for supporting the lower glass sliding door 7 and a vertical slideway located above the horizontal slideway and perpendicular to the horizontal slideway, wherein the horizontal slideway is used to support the lower surface of the lower glass sliding door 7. The vertical slideway of the front extrusion cabinet opening 4 is used to limit the front side of the lower glass sliding door 7, and the vertical slideway 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, a slide bar that cooperates with the slide rail is provided on the lower surface of the lower glass sliding door 7, and the slide bar is preferably made of POM material.

[0046] 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 .

[0047] like Figure 6 As shown, the right injection molding cabinet opening 3 includes an upper side plate 31 located above the upper slide 451 and a lower side plate 32 located above the lower slide 452, a bearing plate 33 is arranged between the upper side plate 31 and the lower side plate 32, the upper side plate 31, the bearing plate 33 and the lower side plate 32 are connected in sequence, and the upper side plate 31 and the bearing plate 33 are in a vertical state, and the bearing plate 33 and the lower side plate 32 are in a vertical state. The upper side plate 31 is vertically arranged with the upper slide 451, the upper side plate 31 is connected with the upper slide 451, and the joint formed by the upper side plate 31 and the upper slide 451 is located outside the part of the upper slide 451 that bears the upper glass sliding door 6, which can avoid the sense of frustration generated when the upper glass sliding door 6 slides and improve the sealing of the slide. The lower side plate 32 is vertically arranged with the lower slide 452, and the lower side plate 32 is connected with the lower slide 452. The joint formed by the lower side plate 32 and the lower slide 452 is located outside the part where the lower slide 452 supports the lower glass sliding door 7, which can avoid the sense of frustration when the lower glass sliding door 7 slides and improve the sealing of the slide.

[0048] The drainage structure includes a primary drainage filter, which includes an upper slideway drainage filter 311 and a lower slideway drainage filter 321. The upper slideway drainage filter 311 is arranged at a position corresponding to the upper slideway 451 on the upper side plate 31, and the upper slideway drainage filter 311 is located above the horizontal slideway of the upper slideway 451. The lower slideway drainage filter 321 is arranged at a position corresponding to the lower side plate 32 and the lower slideway 452, and the lower slideway drainage filter 321 is located above the horizontal slideway of the lower slideway 452. The height of the upper slideway drainage filter 311 is higher than the height of the lower slideway drainage filter 321. Condensed water on the upper slideway 451 can be discharged through the upper slideway drainage filter 311, and condensed water on the lower slideway 452 can be discharged through the lower slideway drainage filter 321.

[0049] In order to further improve the drainage effect, the primary drainage filter unit also includes an auxiliary drainage filter unit 331, which is arranged on the support plate 33 near the upper slideway 451, and can drain the condensed water on the support plate 33 and part of the upper slideway 451. The support plate 33 is connected to the horizontal slideway of the upper slideway 451, and the auxiliary drainage filter unit 331 is located at the position where the support plate 33 is connected to the horizontal slideway of the upper slideway 451.

[0050] In this embodiment, the drainage structure includes a secondary drainage filter portion 34, which is used to receive condensed water discharged from the primary filter drainage portion. This embodiment can perform secondary filtration on the condensed water to avoid dirt and blockage of the drainage structure.

[0051] Specifically, Figure 8-10 As shown, the secondary drainage filter 34 is located below the lower slideway drainage filter 321 and the auxiliary drainage filter 331, and is used to receive the condensed water from the lower slideway drainage filter 321 and the auxiliary drainage filter 331, and perform secondary filtration on the condensed water from the lower slideway drainage filter 321 and the auxiliary drainage filter 331. The drainage structure includes a guide 35, which is used to guide the condensed water from the upper slideway drainage filter 311 to the secondary drainage filter 34, and the secondary drainage filter 34 performs secondary filtration on the condensed water from the upper slideway drainage filter 311 to ensure the filtering effect.

[0052] Of course, the following situations are also within the protection scope of the present invention:

[0053] 1. The upper slide drainage filter section does not pass through the secondary drainage filter section for secondary filtration, and the lower slide drainage filter section and the auxiliary drainage filter section pass through the secondary drainage filter section for secondary filtration.

[0054] 2. The upper slide drainage filter section includes a secondary drainage filter section, and the condensed water of the upper slide drainage filter section is filtered twice through the secondary drainage filter section. The lower slide drainage filter section and the auxiliary drainage filter section do not include the secondary drainage filter section, and the lower slide drainage filter section and the auxiliary drainage filter section do not pass through the secondary drainage filter section for secondary filtration.

[0055] 3. The upper slide drainage filter section includes a first secondary drainage filter section, and the condensed water of the upper slide drainage filter section is secondary filtered through the first secondary drainage filter section. The lower slide drainage filter section and the auxiliary drainage filter section include a second secondary drainage filter section, and the lower slide drainage filter section and the auxiliary drainage filter section are secondary filtered through the second secondary drainage filter section.

[0056] In this embodiment, Figure 6 , 7 As shown in FIGS. 9 and 10, the upper slideway drainage filter part 311 is directly formed on the upper side plate 31 and is a part of the upper side plate 31. The upper slideway drainage filter part 311 and the upper side plate 31 are injection molded at one time. The drainage filter port of the upper slideway drainage filter part 311 is a plurality of notches opened at the bottom of the upper side plate 31. The diameter of the notches is very small and the notches are used to achieve drainage and filtering. The notches can be directly formed during the injection molding process of the right injection molding cabinet mouth part 3, and there is no need to process them after the side plate is processed. They can be formed at one time, which greatly simplifies the processing technology of the drainage filter port.

[0057] like Figure 7 As shown, a mounting position 231 is provided on the lower side plate 32 and the bearing plate 33, and the lower slideway drainage filter portion 321 and the auxiliary drainage filter mounting portion 331 are detachably mounted on the mounting position 231. At this time, the lower slideway drainage filter portion 321 and the auxiliary drainage filter mounting portion 331 can be disassembled to clean the drainage structure. The lower slideway drainage filter portion 321 and the auxiliary drainage filter mounting portion 331 of this embodiment are detachably mounted. When the drainage structure is blocked by dirt and causes poor drainage, the lower slideway drainage filter portion 321 and the auxiliary drainage filter mounting portion 331 can be removed to clean the drainage structure to ensure smooth drainage.

[0058] like Figure 8 As shown, in this embodiment, the lower slideway drainage filter 321 and the auxiliary drainage filter 331 are preferably integrally formed, and the lower slideway drainage filter 321 and the auxiliary drainage filter 331 are connected together by a support member 36, and the support member 36 is clamped on the installation position 231 of the cabinet opening through a clamping structure. A secondary drainage filter 34 is arranged at the bottom of the support member 36. In this embodiment, the component formed by the lower slideway drainage filter 321, the auxiliary drainage filter 331, the secondary drainage filter 34 and the support member 36 is called a drainage filter plug.

[0059] like Figure 7 , 8 As shown in FIG. 10 , the drainage filter plug is clamped on the installation position 231 through a clamping structure.

[0060] The drainage filter plug includes a support member 36 that forms a cavity structure, and the lower slideway drainage filter portion 321, the auxiliary drainage filter portion 331 and the secondary drainage filter portion 34 are connected together through the support member 36. Preferably, the lower slideway drainage filter portion 321, the auxiliary drainage filter portion 331, the secondary drainage filter portion 34 and the support member 36 are integrally injection molded.

[0061] The support member 3636 has a drainage side plate 361 and a drainage top plate 362. When the support member 36 is installed on the installation position 231, the outer surface of the drainage side plate 361 is connected to the outer surface of the lower side plate 32 and is located on the same plane; the outer surface of the drainage top plate 362 is connected to the outer surface of the supporting plate 33 and is located on the same plane.

[0062] The drainage filter openings of the lower slideway drainage filter 321 are several notches formed on the drainage side plate 362. The notches have a very small diameter and are used for drainage and filtration. The notches can be directly formed during the process of injection molding the lower slideway drainage filter 321, without the need to process the lower slideway drainage filter 321 after processing. The drainage filter 321 can be formed in one step, which greatly simplifies the processing technology of the drainage opening.

[0063] The secondary drainage filter 34 is formed at the bottom of the support member 36 , and the filter hole size of the secondary drainage filter 34 is smaller than the filter hole sizes of the upper slideway drainage filter 311 , the lower slideway drainage filter 321 and the auxiliary drainage filter 331 .

[0064] In this embodiment, a guide portion 35 is provided on the inner side of the upper side plate 31 , and an opening 361 for receiving condensed water guided by the guide portion 35 is provided above the secondary drainage filter portion 34 on the support member 36 . The opening 361 is located above the secondary drainage filter portion 34 .

[0065] The drainage filter plug is mounted on the installation position 231 through a clamping structure. Figure 8 As shown, the support member 36 includes two side plates 364 perpendicular to the drainage side plates 362, and the clamping structure includes two elastic buckles 3641 located on the two side plates 364. When the elastic buckles 3641 on the current side plates 364 are all located on the surface of the current side plate 364 away from the other side plate 364.

[0066] like Figure 7As shown, a step structure 235 is provided on the installation position 231, and the step structure 235 is used to assemble with the drainage top plate 236. When the drainage filter plug is clamped on the installation position 231 through the clamping structure, the drainage top plate 236 is clamped on the step structure 235, and the elastic buckle 3641 is clamped with the bottom end of the installation position 231.

[0067] When the drainage filter plug is installed to the installation position 231, it is only necessary to push the support member 36 from top to bottom toward the installation position 231. Under the action of the installation position 23, the two elastic buckles 3641 undergo elastic deformation and deform toward each other until the elastic buckles 3641 reach the bottom end of the installation position 321. The elastic buckle 3641 is reset, and the elastic buckle 3641 is clamped with the bottom end of the installation position 231. The drainage top plate 363 is assembled with the step structure 235 to complete the installation of the support member 36.

[0068] In order to ensure the drainage effect, the upper slideway drainage filter 311, the lower slideway drainage filter 321 and the auxiliary drainage filter 331 all have a filtering function, which can filter the debris in the condensed water to prevent the debris from clogging the drainage structure, resulting in poor drainage or no drainage. In this embodiment, even if there are debris clogging the drainage structure, the drainage can be removed from the installation position 231 to clean the drainage structure.

[0069] Of course, the following schemes are all within the protection scope of the present invention: the upper slide drainage filter portion is detachably mounted on the upper side plate, and / or the lower slide drainage filter portion is detachably mounted on the lower side plate, and / or the auxiliary drainage filter portion is detachably mounted on the supporting plate.

[0070] In this embodiment, Fig.11 As shown, when the upper glass sliding door 6 contacts the upper side plate 31 of the right injection molded cabinet opening 3, the upper glass sliding door 6 is used to seal the upper slideway drainage filter 311 of the upper side plate 31 of the right injection molded cabinet opening 3 in the refrigerator. A soft sealing strip 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 on the side of the upper glass sliding door 6 contacts the upper side plate 31. Therefore, the upper glass sliding door 6 of this embodiment can seal the upper slideway drainage filter of the upper side plate 23 of the right injection molded cabinet opening 3 in the refrigerator. The sealing performance of the cabinet opening in this embodiment at the drainage filter part is greatly improved, which prevents the air inside the cabinet and the external air from flowing in the drainage filter part of the side plate, improves the refrigeration efficiency of the refrigerator, and reduces frosting.

[0071] Therefore, when the upper glass sliding door 6 closes the cabinet opening, the condensed water on the lower slide 452 can be discharged through the lower drainage filter of the right injection molded cabinet opening 3; the condensed water on the upper slide 451 can be discharged through the upper drainage filter and the auxiliary drainage filter of the right injection molded cabinet opening 3. When the upper glass sliding door 6 slides toward the right injection molded cabinet opening 3, the condensed water on the upper slide 451 can be discharged through the upper drainage filter and the auxiliary drainage filter of the right injection molded cabinet opening 2.

[0072] In this embodiment, since the height of the rear extruded cabinet opening 5 is higher than the height of the front extruded cabinet opening 4, the condensed water on the glass sliding door is generally accumulated on the front extruded cabinet opening 4. Therefore, in this embodiment, it is only necessary to set a drainage filter part at the position corresponding to the right injection molded cabinet opening 3 and the front extruded cabinet opening 4 (that is, the side plate 23 at the front end of the left injection molded cabinet opening 2). Of course, in order to avoid the accumulation of condensed water at the rear extruded cabinet opening 5 and ensure the drainage of the rear extruded cabinet opening 5, a drainage filter part can also be set at the position corresponding to the right injection molded cabinet opening 3 and the rear extruded cabinet opening 5 (that is, the side plate at the rear end of the right injection molded cabinet opening 3). The setting form of the drainage filter at the rear end of the right injection molded cabinet opening 3 is the same as the setting form at the front end of the right injection molded cabinet opening 3, which will not be repeated here. The form of setting drainage filters at both the front and rear ends of the right injection molded cabinet opening 3 is particularly suitable for the case where the heights of the front extruded cabinet opening and the rear extruded cabinet opening are the same.

[0073] In this embodiment, a drainage part for receiving condensed water discharged from the upper slide drainage filter part 311, the auxiliary drainage filter part 331 and the lower slide drainage filter part 321 is provided on the inner side of the upper side plate 31, the lower side plate 32 and the supporting plate 33. 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.

[0074] Specifically, Fig. 9 , 10 As shown, the drainage part includes a drainage funnel 38 located below the lower slideway drainage filter part 321, and the drainage funnel 38 receives the condensed water flowing down from the secondary drainage filter part 34. The drainage funnel 38 has a certain water storage capacity, which can avoid the problem that the condensed water on the slideway cannot be discharged in time and flows into the cabinet when there is a large amount of condensed water.

[0075] For the convenience of processing, the drainage funnel 38 and the guide portion 35 are integrally formed.

[0076] The right injection molding cabinet mouth part 3 is provided with a mounting structure for mounting the drainage part.
