Description

Technical Field

[0001] This application relates to the field of freezer technology, specifically providing a freezer liner and a freezer. Background Technology

[0002] Currently, freezers on the market need to be designed with an air duct system to ensure the cooling effect inside the freezer. Because there are clearance steps inside the freezer liner, these steps can obstruct airflow, thus affecting the airflow effect of the freezer liner and the temperature uniformity of the entire freezer. In addition, because the clearance steps are raised on the freezer liner, water or ice can easily accumulate on the surface of the clearance steps. Summary of the Invention

[0003] This application aims to solve the aforementioned technical problems, namely, to address the issues of uneven temperature distribution inside freezers with steps or water accumulation on steps in existing technologies.

[0004] This application provides a freezer liner, which includes a step to avoid obstacles. The side of the step near the opening of the freezer liner is set as an inclined surface, projected along a direction perpendicular to the side wall of the freezer liner. The height of the end of the inclined surface away from the opening is higher than the height of the end of the inclined surface near the opening. The freezer liner also includes an air inlet channel and an air outlet channel, both of which connect the freezer liner to its external space. The air outlet channel is located on the side of the freezer liner away from the opening.

[0005] In the above-mentioned optional technical solution for the freezer liner, a groove is provided on the clearance step. The groove extends from one end near the opening end to the end away from the opening end on the clearance step. The end of the groove away from the opening end communicates with the external space of the freezer liner to form the air outlet channel.

[0006] In the above-mentioned optional technical solution for the freezer inner liner, the freezer inner liner further includes a flow guiding component. The flow guiding component is disposed on the avoidance step and away from the opening end. One end of the groove is located at the bottom of the flow guiding component. A fan can be disposed on the flow guiding component. A first flow guiding channel is disposed on the flow guiding component. The first flow guiding channel is the air inlet channel, so that the fan can send air into the freezer inner liner through the first flow guiding channel.

[0007] In the above-mentioned optional technical solution for the freezer liner, the air guiding component includes an inner panel and an outer panel. The inner panel faces the freezer liner, and the outer panel faces away from the freezer liner. An air guiding cavity is formed between the inner panel and the outer panel. The first air guiding channel is disposed on the inner panel and connects the freezer liner and the air guiding cavity. A fan can be disposed on the outer panel so that the fan can deliver air into the freezer liner through the air guiding cavity and the first air guiding channel.

[0008] In the above-mentioned optional technical solution for the freezer liner, the air guiding component further includes a bottom plate, the outer plate and the inner plate abut against the bottom plate, and a plurality of air guiding plates are provided on the side of the bottom plate away from the outer plate. A second air guiding channel is formed between two adjacent air guiding plates. The second air guiding channel connects the freezer liner with its external space. The freezer liner exhausts air to the outside of the freezer liner through the second air guiding channel. The groove is located at the bottom of the second air guiding channel and each groove corresponds to one second air guiding channel.

[0009] In the above-mentioned optional technical solution for the freezer liner, a drainage groove is provided between the open end of the freezer liner and the clearance step, and a drain outlet is provided in the drainage groove. The drainage groove is inclined from its edge toward the drain outlet so that the water in the drainage groove can flow into the drain outlet.

[0010] In the above-mentioned optional technical solution for the inner liner of the freezer, a number of protrusions are provided in the drainage groove, and flow channels are formed between adjacent protrusions and between the protrusions and the edge of the drainage groove, and the flow channels are connected to the drain outlet.

[0011] In the above-mentioned optional technical solutions for the freezer liner, a shelf is provided above the drain groove, and a gap is provided between the shelf and the drain groove so that the liquid sliding down the inclined surface can flow into the drain groove through the gap.

[0012] In the above-mentioned optional technical solutions for the freezer liner, the shelf is provided with a number of drainage holes, which are connected to the drainage groove.

[0013] This application also provides a freezer, which includes the freezer liner described in any one of the technical solutions.

[0014] When the above technical solution is adopted, this application can reduce wind resistance by setting the avoidance step at an angle. When the air between the avoidance step and the opening end encounters the inclined surface, it can also be guided by the inclined surface to flow towards the air outlet channel. The setting of the inclined surface can also guide water to flow along the inclined surface, thereby avoiding liquid accumulation on the avoidance step. Attached Figure Description

[0027] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. Unless otherwise stated, the terms "upper," "lower," "bottom," "inner," and "outer," indicating orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings and are used only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0028] The terms "first," "second," "third," and similar terms used in this application specification and claims do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Furthermore, "multiple" or "several" in this application refers to two or more. This application provides a freezer 1, which includes a freezer liner 10. Further, a flow guide assembly 12 is disposed within the freezer liner 10. The freezer 1 also includes a door, opening which reveals the interior of the freezer liner 10.

[0029] It should be noted that the door of the freezer 1 in this application is located at the opening end 10a of the freezer inner liner 10. The opening end 10a of the freezer inner liner 10 is referred to as the opening end 10a below. In order to show the structure of the freezer inner liner 10 inside the freezer 1, the door is not shown in the figure. Figures 1 to 3 In the diagram, the x-direction is perpendicular to the opening end 10a, the y-direction is perpendicular to the side wall 101 of the inner liner 10 of the freezer, the z-direction points upwards, and the y-direction is parallel to the plane where the door is located.

[0030] It should also be noted that the freezer 1 of this application can be used as a display freezer. In this case, the door of the freezer 1 can be a transparent door. The freezer 1 can include one freezer inner liner 10 or two freezer inner liners 10 stacked vertically. When the freezer 1 includes two freezer inner liners 10 stacked vertically, both freezer inner liners 10 can be used for freezing, or both can be used for refrigeration, or one can be used for freezing and the other for refrigeration. The above are not limiting and can be set according to the needs of those skilled in the art. This application describes the freezer 1 including two freezer inner liners 10, and the two freezer inner liners 10 stacked vertically, as an example. Furthermore, it describes the example of the upper freezer inner liner 10 being used for refrigeration and the lower freezer inner liner 10 being used for freezing.

[0031] In addition, the inner liner 10 of a freezer used for freezing generally requires ventilation. Therefore, the accompanying drawings all illustrate the inner liner 10 of a freezer as being positioned at the bottom. However, this is not limiting; the inner liner 10 of a refrigerator can also be ventilated. Those skilled in the art can configure the inner liner 10 of this application as either a refrigerator inner liner 10 or a freezer inner liner 10 according to their needs. It should also be noted that, in order to clearly show the internal structure of the inner liner 10 of a freezer, Figure 2 and Figure 4 Only part of the freezer liner 10 was retained.

[0032] like Figure 1 , Figure 2 As shown, a freezer 1 is provided. The freezer 1 includes the freezer liner 10 described in this application. The freezer liner 10 includes a step 11 for avoiding obstacles. The side of the step 11 near the opening end 10a of the freezer liner 10 is set as an inclined surface 111. Projected along a direction perpendicular to the side wall 101 of the freezer liner 10, the height of the end of the inclined surface 111 away from the opening end 10a is higher than the height of the end of the inclined surface 111 near the opening end 10a. The freezer liner also includes a first air intake channel 1211, which serves as an air intake channel. The freezer liner also includes a second air intake channel 1241, which serves as an air outlet channel. Both the air intake channel and the air outlet channel connect the freezer liner to its external space. The air outlet channel is located on the side of the freezer liner away from the opening end 10a.

[0033] To further enhance the freezing effect of the freezer liner 10, this application supplies cold air released from the evaporator 19 to the freezer liner 10 and exhausts the gas inside the freezer liner 10 to the outside, with the gas circulating inside the freezer liner 10 as follows: Figure 2As indicated by the arrow, the freezer inner liner 10 is connected to the external space of the freezer inner liner 10, and cold air from the outside is introduced into the freezer inner liner 10 through the air intake channel, thereby increasing the freezing effect of the freezer inner liner 10. Generally, the space outside the freezer inner liner 10 and at the bottom of the clearance step 11 is for placing other components, such as compressors. Therefore, the clearance step 11, being a protrusion inside the freezer inner liner 10, can easily obstruct the airflow from the freezer inner liner 10, thus affecting the temperature uniformity inside the freezer inner liner 10. To reduce the impact of the clearance step 11 on the air outlet of the freezer inner liner 10, the clearance step 11 is set at an angle, that is, the height of the end of the clearance step 11 closer to the opening end 10a is lower than the height of the end farther from the opening end 10a. At this time, the angled clearance step 11 can reduce the wind resistance. When the air between the clearance step 11 and the opening end 10a encounters the inclined surface 111, it can also be guided by the inclined surface 111 to flow in the direction of the air outlet channel, and thus flow to the outside of the freezer inner liner 10 through the flow guide component 12, thereby reducing the wind resistance of the freezer inner liner 10 and improving the uniformity of its internal temperature.

[0034] In addition, the inclined surface 111 can also guide the water flow, allowing the water to flow along the inclined surface 111 to the space between the clearance step 11 and the opening end 10a, where the water is collected or discharged. This prevents water from accumulating on the clearance step 11 or other locations in the freezer liner 10, thus avoiding any impact on the cooling effect of the freezer liner 10. It should be noted that the inclined surface 111 can be a flat surface or a curved surface. A curved surface can further reduce air resistance. The above can be configured according to the needs of those skilled in the art.

[0035] In one embodiment, such as Figures 1 to 3 As shown, a groove 112 is provided on the clearance step 11. The groove 112 extends from the end near the opening end 10a to the end away from the opening end 10a on the clearance step 11. The end of the groove 112 away from the opening end 10a is connected to the external space of the freezer inner liner 10. The part of the groove 112 connected to the external space forms an air outlet channel, so that the freezer inner liner 10 can exhaust air to the outside of the freezer inner liner 10 through the air outlet channel.

[0036] Because the groove 112 can communicate with the external space of the freezer inner liner 10, and because the groove 112 can serve as a channel for airflow, air can be drawn out in an orderly manner through the groove 112 when the freezer inner liner 10 is venting, thereby further improving the ventilation effect. In addition, the groove 112 also guides water flow, causing water on the clearance step 11 to first collect in the groove 112 and flow downwards along it. Furthermore, when items inside the refrigerator accidentally fall onto the clearance step 11, the groove 112 provides sufficient space for airflow between it and the fallen items, allowing air from the freezer inner liner 10 to still flow outwards through the groove 112. Therefore, the ventilation effect and temperature uniformity of the freezer inner liner 10 are also ensured.

[0037] In one embodiment, such as Figure 1 , Figure 2 As shown, the freezer inner liner 10 also includes a flow guiding component 12. When the flow guiding component 12 is installed inside the freezer inner liner 10, it is installed on the clearance step 11 of the freezer inner liner 10 and away from the opening end 10a. When the clearance step 11 is provided with a groove 112, one end of the groove 112 is located at the bottom of the flow guiding component 12. At this time, an air outlet channel is formed between the groove 112 and the bottom of the flow guiding component 12. A fan 18 can be installed on the flow guiding component 12. A first flow guiding channel 1211 is provided on the flow guiding component 12. The first flow guiding channel 1211 can serve as an air inlet channel, so that the fan 18 delivers air into the freezer inner liner 10 through the first flow guiding channel 1211. The freezer inner liner 10 discharges air to the outside of the freezer inner liner 10 through the groove 112 (i.e., the air outlet channel formed between the groove 112 and the bottom of the flow guiding component 12). The fan 18 draws the cold air released from the evaporator 19 into the freezer liner 10 through the first guide channel 1211, where it circulates. The fan also expels the air from the freezer liner 10 through the air outlet channel between the groove 112 and the guide assembly 12. The exhausted air is further cooled by the evaporator 19 and then transported back into the freezer liner 10, thus achieving continuous cooling of the freezer liner 10. This configuration ensures continuous cooling of the freezer liner 10 and guarantees temperature uniformity within it.

[0038] In addition, since the first flow channel 1211 is provided on the flow guide component 12 and the first flow channel 1211 blows towards the opening end 10a, when the first flow channel 1211 blows air out, it can also blow onto the avoidance step 11 and the surface of the inclined surface 111. At this time, the water on the inclined surface 111 can accelerate downwards under the influence of the wind, thereby accelerating the convergence towards the direction between the opening end 10a and the avoidance step 11. The cooperation between the first flow channel 1211 and the inclined surface 111 further reduces the possibility of water freezing on the avoidance step 11.

[0039] In one embodiment, the airflow guiding component 12 further includes a second airflow guiding channel 1241, and the freezer liner 10 can exhaust air to the outside of the freezer liner 10 through the second airflow guiding channel 1241, thereby ensuring the ventilation effect of the freezer liner 10. When the relief step 11 of the freezer liner 10 is also provided with a groove 112, both the groove 112 and the second airflow guiding channel 1241 can realize the airflow of the freezer liner 10. Therefore, the provision of the second airflow guiding channel 1241 further improves the airflow efficiency of the freezer liner 10, thereby further improving the temperature uniformity inside the freezer liner 10.

[0040] It should be noted that the airflow guiding component 12 can be installed independently inside the freezer liner 10 without needing to cooperate with the groove 112. In this case, the airflow guiding component 12 includes a first airflow guiding channel 1211 and a second airflow guiding channel 1241. Air intake is achieved through the first airflow guiding channel 1211, and air outlet is achieved through the second airflow guiding channel 1241. The above is not restrictive, and the above can be configured according to the needs of those skilled in the art.

[0041] In one embodiment, such as Figures 6 to 8 As shown, the airflow guiding assembly 12 includes an inner plate 121 and an outer plate 122. The inner plate 121 faces the freezer inner liner 10, and the outer plate 122 faces away from the freezer inner liner 10. An airflow guiding cavity 12a is formed between the inner plate 121 and the outer plate 122. A first airflow guiding channel 1211 is provided on the inner plate 121, which connects the freezer inner liner 10 and the airflow guiding cavity 12a. A fan 18 can be provided on the outer plate 122 so that the fan 18 can deliver air into the freezer inner liner 10 through the airflow guiding cavity 12a and the first airflow guiding channel 1211.

[0042] Since the fan 18 does not directly contact the freezer liner 10, and the gas delivered by the fan 18 to the freezer liner 10 first passes through the guide cavity 12a, it does not cause airflow turbulence in the freezer liner 10. Because the guide cavity 12a is only connected to the freezer liner 10 through the first guide channel 1211, the gas in the guide cavity 12a can be dispersed into the freezer liner 10 through the first guide channel 1211, thus achieving uniform flow of gas from the guide cavity 12a into the freezer liner 10. The first guide channel 1211 can be set to one or more. When multiple first guide channels 1211 are provided, the gas in the guide cavity 12a can flow into the freezer liner 10 more evenly.

[0043] In one embodiment, the airflow guiding assembly 12 further includes a base plate 123. An outer plate 122 and an inner plate 121 abut against the base plate 123. A plurality of airflow guiding plates 124 are provided on the side of the base plate 123 away from the outer plate 122. A second airflow guiding channel 1241 is formed between two adjacent airflow guiding plates 124. When the step 11 is provided with a groove 112, the groove 112 is located at the bottom of the second airflow guiding channel 1241, and each groove 112 corresponds to one second airflow guiding channel 1241. By forming multiple second airflow guiding channels 1241 at the bottom of the base plate 123, the orderly airflow of the freezer liner 10 can be ensured, thereby improving airflow efficiency. The groove 112 located at the bottom of the second airflow guiding channel 1241 can further increase the airflow area of ​​the corresponding second airflow guiding channel 1241, thereby increasing the airflow volume and further improving the airflow effect. In addition, when an item falls onto the clearance step 11, it will block part of the second airflow channel 1241 and reduce the airflow effect. However, when the clearance step 11 is provided with a groove 112, the air inside the freezer liner 10 can flow through the groove 112 into the second airflow channel 1241 and out along the second airflow channel 1241. Thus, when an item falls onto the clearance step 11, the freezer liner 10 can still ventilate smoothly, thereby ensuring the cooling effect of the freezer liner 10.

[0044] It should be noted that, in order to ensure the air outlet effect, a second airflow channel 1241 can be formed between two adjacent guide plates 124. Grooves 112 are spaced apart at the bottom of the second airflow channel 1241. Therefore, the number of second airflow channels 1241 is greater than the number of grooves 112. Each groove 112 corresponds to one second airflow channel 1241, but not every second airflow channel 1241 corresponds to one groove 112. Of course, the grooves 112 can also be matched one-to-one with the second airflow channels 1241. This is not limiting; the configuration can be made according to the needs of those skilled in the art, and all of the above are within the scope of protection of this application.

[0045] It should also be noted that the second flow channel 1241 can be located at the bottom of the flow guide assembly 12 or on the side. Furthermore, the flow guide assembly 12 can also consist of only one plate, on which the first flow channel 1211, the second flow channel 1241, and the fan 18 are all mounted. As long as the fan 18 can intake air into the freezer liner 10 through the first flow channel 1211 and the freezer liner 10 can exhaust air from the second flow channel 1241, all of the above are within the scope of protection of this application.

[0046] In one embodiment, such as Figure 7 As shown, the inner panel 121 and the outer panel 122 are detachably connected, and can be replaced in time if any component of the inner panel 121 or the outer panel 122 is damaged.

[0047] In one embodiment, such as Figure 7 As shown, the base plate 123, inner plate 121, and guide plate 124 are integrally formed, or the base plate 123, outer plate 122, and guide plate 124 are integrally formed. This application describes the integral forming of the base plate 123, outer plate 122, and guide plate 124 as an example. Integrating the above components into one piece can reduce assembly steps, save installation time, and eliminate the need for multiple mold openings.

[0048] It should be noted that the inner panel 121 and the outer panel 122 can be directly connected or connected together through other components. Those skilled in the art will understand the specific meaning of the above terms in this application according to the specific circumstances.

[0049] In one embodiment, such as Figures 6 to 8 As shown, the flow guiding component 12 also includes a water receiving trough 125, which passes through the outer panel 122 and the inner panel 121 and communicates with the external space of the freezer inner liner 10. The flow guiding component 12 not only has an air guiding function but also a water guiding function. By setting the water receiving trough 125 on the flow guiding component 12, when there are water droplets inside the freezer inner liner 10 or on the surface of the flow guiding component 12, the water droplets can flow downward into the water receiving trough 125 and be discharged by the water receiving trough 125 to the outside of the freezer inner liner 10.

[0050] In one embodiment, such as Figure 8 As shown, the water receiving trough 125 is inclined from the first end to the second end, with the first end higher than the second end. The first end is the end of the water receiving trough 125 closest to the inner plate 121, and the second end is the end of the water receiving trough 125 closest to the outer plate 122. Figure 8 The arrows shown indicate the flow direction of water in the water receiving tank 125. Since the inner plate 121 is close to the freezer liner 10 and the outer plate 122 is far away from the freezer liner 10, the first end is higher than the second end. When water falls into the water receiving tank 125, the water can flow from the first end to the second end of the water receiving tank 125 and be discharged to the outside of the freezer liner 10. The above arrangement can prevent water from remaining in the freezer liner 10 and can also prevent water from freezing in the water receiving tank 125.

[0051] In one embodiment, such as Figure 6 , Figure 7As shown, a flow guide plate 1212 is provided on the inner plate 121. The flow guide plate 1212 is inclined from one end to the other, and the lowest end of the flow guide plate 1212 is located above the water receiving tank 125, so that liquid can flow along the flow guide plate 1212 into the water receiving tank 125. When water droplets condense on the inner plate 121, the water droplets will flow downwards onto the flow guide plate 1212, and then be guided by the flow guide plate 1212 into the water receiving tank 125. The inclined arrangement of the flow guide plate 1212 ensures that the water droplets can enter the water receiving tank 125 under the guidance of gravity, thereby minimizing water accumulation on the flow guiding component 12.

[0052] In one embodiment, such as Figure 6 As shown, projected along a direction perpendicular to the inner panel 121, the flow guide plate 1212 is located between the first flow guide channel 1211 and the water receiving tank 125. When the flow guide assembly 12 is installed in the freezer liner 10, the direction perpendicular to the inner panel 121 is the same as the direction perpendicular to the opening end 10a. When the cold air flowing into the freezer liner 10 from the first flow guide channel 1211 condenses into water droplets on the inner panel 121, the water droplets can flow along the inner panel 121 to the flow guide plate 1212 and then to the water receiving tank 125, thereby preventing the water droplets from falling on the avoidance step 11 or other locations and freezing inside the freezer liner 10.

[0053] In one embodiment, such as Figure 4 As shown, the freezer inner liner 10 can accommodate the shelf 15, such as Figure 3 As shown, the freezer liner 10 includes a clearance step 11, on which a boss 113 is provided. The side wall 101 of the freezer liner 10 is also provided with a first support member 16, on which a first overlapping part 161 is provided. Figure 4 The shelf 15 shown can be detachably mounted on Figure 3 The boss 113 and the first overlapping portion 161 are shown in the diagram. Normally, no items are placed on the clearance step 11, resulting in a significant waste of internal space in the freezer liner 10. To improve the space utilization of the freezer liner 10, a boss 113 is provided on the clearance step 11, and a shelf 15 is installed on the boss 113 and the first overlapping portion 161, thereby adding a layer of storage space and improving the space utilization of the freezer liner 10. When the user does not need the shelf 15, it can be removed from the freezer liner 10.

[0054] In one embodiment, such as Figure 3As shown, the boss 113 is stepped, including a first stepped surface 1131 and a second stepped surface 1132. Projected along a direction perpendicular to the opening end 10a of the freezer liner 10, the first stepped surface 1131 is higher than the second stepped surface 1132. One end of the shelf 15 can be placed on either the first stepped surface 1131 or the second stepped surface 1132. Users can adjust the position of the shelf 15 on the boss 113 according to their needs. Since the second airflow channel 1241 and the groove 112 are located between the clearance step 11 and the shelf 15, the airflow from the freezer liner 10 needs to pass between the shelf 15 and the clearance step 11. When there are many items on the shelf 15, to ensure sufficient airflow space, the distance between the shelf 15 and the clearance step 11 can be increased, thus placing the shelf 15 on the first stepped surface 1131 to ensure ventilation.

[0055] In one embodiment, such as Figure 2 As shown, the shelf 15 overlaps with the side 152 near the inner panel 121 on the base plate 123. At this time, the base plate 123 can support the shelf 15 to ensure the stability of the shelf 15 placed inside the freezer liner 10.

[0056] In one embodiment, such as Figure 2 , Figure 3 As shown, the side wall 101 of the freezer liner 10 is also provided with a second support member 17. Projected along the direction perpendicular to the side wall 101 of the freezer liner 10, the first support member 16 is located between the opening end 10a of the freezer liner 10 and the clearance step 11, and the second support member 17 is located above the clearance step 11. The second support member 17 is provided with a second overlapping part 171. At the same height as the second overlapping part 171, the first support member 16 is also provided with a corresponding third overlapping part 162.

[0057] The length of the first support member 16 is greater than the length of the second support member 17, so that the first overlapping portion 161 of the first support member 16 can cooperate with the boss 113 to support the shelf 15, thereby improving the space utilization rate. The height of the second overlapping portion 171 on the second support member 17 and the third overlapping portion 162 of the first support member 16 is h1. At this time, other storage devices can be supported on the second overlapping portion 171 and the third overlapping portion 162, and the stability of other storage devices on the second overlapping portion 171 and the third overlapping portion 162 can be ensured at the same height.

[0058] It should be noted that the freezer inner liner 10 is equipped with multiple storage devices, which require the corresponding overlapping parts on the first support member 16 and the second support member 17 for support. This application only describes the support of one layer of storage devices using the second overlapping part 171 and the third overlapping part 162 as an example. The principle of supporting the storage devices of other layers is the same as the principle of supporting the storage devices using the second overlapping part 171 and the third overlapping part 162, and will not be described in detail here.

[0059] In one embodiment, such as Figure 4 As shown, the shelf 15 is provided with a hole 151. When water droplets appear on or above the shelf 15, they can flow into the groove 112 through the hole. In addition, gas can also pass through the hole 151. Therefore, the hole 151 can also improve the flow of gas in the freezer liner 10, thereby improving the temperature uniformity of the freezer liner 10.

[0060] In one embodiment, such as Figure 4 As shown, a drain groove 13 is provided at one end of the inner liner 10 of the freezer near the opening 10a. A drain outlet 131 is provided within the drain groove 13. The drain groove 13 slopes from its edge towards the drain outlet 131, allowing water in the drain groove 13 to flow into the drain outlet 131. When water droplets are present on the clearance step 11, they can slide down the inclined surface 111 or down the groove 112 into the drain groove 13. Due to the reverse slope of the drain groove 13 towards the drain outlet 131, the water in the drain groove 13 flows towards the drain outlet 131 and then flows out from the drain outlet 131. The drain groove 13 further prevents water in the inner liner 10 from freezing.

[0061] In one embodiment, such as Figure 4 As shown, the drainage channel 13 is provided with several protrusions 132, and flow channels 133 are formed between adjacent protrusions 132 and between the protrusions 132 and the edge of the drainage channel 13. (For ease of demonstration,) Figure 4 Only the flow channel 133 formed between adjacent protrusions 132 is shown in the diagram. The flow channel 133 is connected to the drain outlet 131. When water flows into the drain trough 13, it is difficult to collect the water due to the large size of the drain trough 13. At this time, the flow channel 133 can first collect the water initially, and then the water can flow into the drain outlet 131 through the guidance of the flow channel 133. The above arrangement can effectively guide the water in the drain trough 13 and make it drain quickly.

[0062] In one embodiment, such as Figure 5As shown, a shelf 14 is provided above the drain trough 13, and a gap 142 is provided between the shelf 14 and the drain trough 13 so that liquid sliding down the inclined surface 111 can flow into the drain trough 13 through the gap 142. The shelf 14 on the drain trough 13 can hold items, thereby further increasing the space utilization of the freezer liner 10. In addition, the gap 142 between the shelf 14 and the drain trough 13 does not affect the flow of water on the step 11 into the drain trough 13 when the shelf 14 is installed. Furthermore, when the freezer liner 10 includes a flow guide assembly 12, since the flow guide assembly 12 is provided with a first flow guide channel 1211, when the first flow guide channel 1211 blows air in the direction of the opening end 10a, it can blow onto the inclined surface 111. The water on the inclined surface 111 can be accelerated down by the wind and flow quickly through the gap 142 into the drain trough 13 and be discharged from the drain outlet 131, thereby further reducing the problem of ice formation in the freezer liner 10.

[0063] It should be noted that the shelf 14 can be supported by the support legs 141 to leave a gap between the shelf 14 and the drainage channel 13. The support legs 141 can be columnar or strip-shaped. The above is not restrictive and can be set according to the needs of those skilled in the art. All of the above are within the protection scope of this application.

[0064] In one embodiment, such as Figure 5 As shown, the shelf 14 is also provided with several drainage holes 143, which are connected to the drainage channel 13. When there are water droplets on the shelf 14, the water droplets can enter the drainage channel 13 through the drainage holes 143, thereby ensuring that the shelf 14 can hold other items while preventing water accumulation or even freezing on the shelf 14.

[0065] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
