[0027] Here, exemplary embodiments will be described in detail, and examples thereof are shown in the accompanying drawings. Unless otherwise specified, "upper", "lower", "bottom", "inner", "outer", directions or positional relationships indicated are based on directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present application.

[0028] The words "first", "second", "third" and similar terms used in the specification and claims of this application do not indicate any order, quantity or importance, but are only used to distinguish different components. In addition, "multiple" or "several" in this application means two or more. The present application provides a freezer 1, which includes a freezer liner 10. Furthermore, a flow guide assembly 12 is provided in the freezer liner 10. The freezer 1 also includes a door, and the interior of the freezer liner 10 can be seen when the door is opened.

[0029] It should be noted that the door of the freezer 1 of the present application is located at the opening end 10a of the freezer liner 10, and the opening end 10a of the freezer liner 10 is referred to as the opening end 10a hereinafter. In order to be able to show the structure of the freezer liner 10 inside the freezer 1, the door is not shown in the figure. Figures 1 to 3 The x direction is perpendicular to the opening end 10a, the y direction is perpendicular to the side wall 101 of the refrigerator inner container 10, the z direction is upward, 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 the present 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 liner 10 or two freezer liners 10 stacked up and down. When the freezer 1 includes two freezer liners 10 stacked up and down, the two freezer liners 10 can be used for freezing, or both for refrigeration, or one for freezing and the other for refrigeration. The above is not restrictive and can be set according to the needs of those skilled in the art. The present application is introduced by taking the freezer 1 including two freezer liners 10, and the two freezer liners 10 are stacked up and down as an example. Further, the freezer liners 10 arranged at the top are used for refrigeration, and the freezer liners 10 arranged at the bottom are used for freezing as an example.

[0031] In addition, the freezer liner 10 used for freezing generally needs ventilation. Therefore, the drawings all take the freezer liner 10 set at the bottom as an example for freezing. However, the above is not restrictive. The freezer liner 10 used for refrigeration can also be ventilated. Those skilled in the art can set the freezer liner 10 of the present application as a refrigerating freezer liner 10 or a freezing freezer liner 10 according to the needs. It should also be noted that in order to clearly show the internal structure of the freezing freezer liner 10, Figure 2 and Figure 4 Only the part of the freezer liner 10 for freezing is retained.

[0032] like Figure 1 , Figure 2 As shown, a freezer 1 is shown, and the freezer 1 includes a freezer liner 10 to be introduced in the present application. The freezer liner 10 includes an avoidance step 11, and a side of the avoidance step 11 close to 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 close to the opening end 10a. The freezer liner also includes a first guide channel 1211, and the first guide channel 1211 serves as an air inlet channel. The freezer liner also includes a second guide channel 1241, and the second guide channel 1241 serves as an air outlet channel. Both the air inlet channel and the air outlet channel connect the freezer liner with its external space, and the air outlet channel is arranged on the side of the freezer liner away from the opening end 10a.

[0033] In order to further increase the freezing effect of the freezer liner 10, the air sent to the freezer liner 10 by the present application is the cold air released by the evaporator 19, and the gas in the freezer liner 10 is discharged to the outside. The gas circulation in the freezer liner 10 is as follows: Figure 2As shown by the arrow in , the freezer liner 10 is connected to the external space of the freezer liner 10, and the external cold air is introduced into the freezer liner 10 through the air inlet channel, thereby increasing the freezing effect of the freezer liner 10. Generally, outside the freezer liner 10 and at the bottom of the avoidance step 11 is a space for placing other components, which may include a compressor, etc. Therefore, the avoidance step 11 is provided in the freezer liner 10 in a convex form to easily block the freezer liner 10 from blowing outward, thereby affecting the temperature uniformity in the freezer liner 10. In order to reduce the influence of the avoidance step 11 on the air outlet of the freezer inner tank 10, the avoidance step 11 is inclined, that is, the height of the end of the avoidance step 11 close to the opening end 10a is lower than the height of the end away from the opening end 10a. At this time, the inclined avoidance step 11 can reduce wind resistance. After the air between the avoidance 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, thereby flowing to the outside of the freezer inner tank 10 through the guide component 12, thereby reducing the wind resistance of the freezer inner tank 10 and improving the uniformity of its internal temperature.

[0034] In addition, the setting of the inclined surface 111 can also guide the water flow to a certain extent, so that the water can flow along the inclined surface 111 to the space between the avoidance step 11 and the open end 10a, and the water is gathered or discharged at this position, thereby preventing the refrigerator liner 10 from accumulating water on the avoidance step 11 or other positions and affecting the refrigeration effect of the refrigerator liner 10. It should be noted that the inclined surface 111 can be set as a plane or a curved surface, and the curved surface can further reduce the wind resistance, which can be set according to the needs of those skilled in the art.

[0035] In one embodiment, if Figures 1 to 3 As shown, a groove 112 is provided on the avoidance step 11, and the groove 112 extends from an end close to the opening end 10a to an end away from the opening end 10a on the avoidance step 11. The end of the groove 112 away from the opening end 10a is connected with the external space of the freezer inner tank 10, and the part of the groove 112 connected with the external space forms an air outlet channel, so that the freezer inner tank 10 can discharge air to the outside of the freezer inner tank 10 through the air outlet channel.

[0036] Since the groove 112 can be communicated with the external space of the refrigerator liner 10, and the groove 112 can serve as a guide channel for air flow, when the refrigerator liner 10 is discharged, the air can be orderly led out through the groove 112, thereby further improving the air discharge effect. In addition, the setting of the groove 112 can also further play the effect of guiding the water flow, so that the water on the avoidance step 11 first gathers in the groove 112 and flows downward along the groove 112. In addition, when the items in the refrigerator accidentally fall onto the avoidance step 11, due to the setting of the groove 112, there can still be a space for air flow between the groove 112 and the items that fall onto the avoidance step 11, so that the wind of the refrigerator liner 10 can still flow outward through the groove 112, therefore, the air discharge effect of the refrigerator liner 10 and the uniformity of its temperature can also be guaranteed.

[0037] In one embodiment, if Figure 1 , Figure 2 As shown, the freezer liner 10 also includes a guide component 12. When the guide component 12 is arranged in the freezer liner 10, the guide component 12 is arranged on the avoidance step 11 of the freezer liner 10 and away from the opening end 10a. When the avoidance step 11 is provided with a groove 112, one end of the groove 112 is located at the bottom of the guide component 12. At this time, an air outlet channel is formed between the groove 112 and the bottom of the guide component 12. The fan 18 can be arranged on the guide component 12. The first guide channel 1211 is arranged on the guide component 12. The first guide channel 1211 can serve as an air inlet channel, so that the fan 18 supplies air to the freezer liner 10 through the first guide channel 1211, and the freezer liner 10 discharges air to the outside of the freezer liner 10 through the groove 112 (i.e., the air outlet channel formed between the groove 112 and the bottom of the guide component 12). The fan 18 discharges the cold air released by the evaporator 19 into the freezer inner liner 10 through the first guide channel 1211 and circulates in the freezer inner liner 10, and discharges the gas in the freezer inner liner 10 outward through the air outlet channel between the groove 112 and the guide component 12, and the discharged gas is further cooled by the evaporator 19 and then transported to the freezer inner liner 10, thereby realizing continuous refrigeration of the freezer inner liner 10. The above arrangement can realize continuous refrigeration of the freezer inner liner 10 and ensure the temperature uniformity in the freezer inner liner 10.

[0038] In addition, since the first guide channel 1211 is provided on the guide component 12, and the first guide channel 1211 blows in the direction of the opening end 10a, the first guide channel 1211 can also blow to the avoidance step 11 and the surface of the inclined surface 111 when the wind is discharged. At this time, the water on the inclined surface 111 can slide downward faster when driven by the wind, thereby accelerating to converge in the direction between the opening end 10a and the avoidance step 11. The cooperation between the above-mentioned first guide channel 1211 and the inclined surface 111 further reduces the possibility of water freezing on the avoidance step 11.

[0039] In one embodiment, the flow guide assembly 12 further includes a second flow guide channel 1241, and the freezer liner 10 can discharge air to the outside of the freezer liner 10 through the second flow guide channel 1241, thereby ensuring the ventilation effect of the freezer liner 10. When the avoidance step 11 of the freezer liner 10 is further provided with a groove 112, the groove 112 and the second flow guide channel 1241 can both realize the discharge of air from the freezer liner 10, therefore, the provision of the second flow guide channel 1241 further improves the air discharge efficiency of the freezer liner 10, thereby further improving the temperature uniformity in the freezer liner 10.

[0040] It should be noted that the guide assembly 12 can be separately arranged in the refrigerator inner tank 10 without being matched with the groove 112. In this case, the guide assembly 12 includes a first guide channel 1211 and a second guide channel 1241. Air intake is achieved through the first guide channel 1211, and air outlet is achieved through the second guide channel 1241. The above is not restrictive and can be set according to the needs of those skilled in the art.

[0041] In one embodiment, if Figures 6 to 8 As shown, the guide assembly 12 includes an inner plate 121 and an outer plate 122, the inner plate 121 faces the freezer inner tank 10, and the outer plate 122 faces away from the freezer inner tank 10, and a guide cavity 12a is formed between the inner plate 121 and the outer plate 122, and a first guide channel 1211 is provided on the inner plate 121, and the first guide channel 1211 connects the freezer inner tank 10 with the guide cavity 12a, and a fan 18 can be provided on the outer plate 122 to enable the fan 18 to supply air to the freezer inner tank 10 through the guide cavity 12a and the first guide channel 1211.

[0042] Since the fan 18 does not directly contact the freezer liner 10, and the gas delivered to the freezer liner 10 by the fan 18 must first pass through the guide cavity 12a, the airflow in the freezer liner 10 will not be disturbed. Since the guide cavity 12a is connected to the freezer liner 10 only 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, so that the gas in the guide cavity 12a flows evenly into the freezer liner 10. The first guide channel 1211 can be set to one or more. When the first guide channel 1211 is set to multiple, the gas in the guide cavity 12a can flow into the freezer liner 10 more evenly.

[0043] In one embodiment, the guide assembly 12 further includes a bottom plate 123, the outer plate 122 and the inner plate 121 are in contact with the bottom plate 123, a plurality of guide plates 124 are provided on a side of the bottom plate 123 away from the outer plate 122, a second guide channel 1241 is formed between two adjacent guide plates 124, and when the avoidance step 11 is provided with a groove 112, the groove 112 is located at the bottom of the second guide channel 1241 and each groove 112 corresponds to a second guide channel 1241. By forming a plurality of second guide channels 1241 at the bottom of the bottom plate 123, the orderliness of the air outlet of the freezer inner tank 10 can be ensured, thereby improving the air outlet efficiency, and the groove 112 is provided at the bottom of the second guide channel 1241 to further increase the air outlet area of ​​the corresponding second guide channel 1241, thereby increasing the air outlet volume and further improving the air outlet effect. In addition, when an object falls on the avoidance step 11, part of the second guide channel 1241 will be blocked, thereby reducing the air outlet effect. When a groove 112 is provided on the avoidance step 11, the air in the freezer liner 10 can flow into the second guide channel 1241 through the groove 112 and flow out along the second guide channel 1241. Therefore, when an object falls on the avoidance step 11, the air in the freezer liner 10 can be smoothly discharged, 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 guide channel 1241 can be formed between two adjacent guide plates 124, and the grooves 112 are arranged at intervals at the bottom of the second guide channel 1241. Therefore, the number of the second guide channels 1241 is greater than the number of the grooves 112, and each groove 112 can correspond to a second guide channel 1241, but not every second guide channel 1241 can correspond to a groove 112. Of course, the grooves 112 and the second guide channels 1241 can also be matched one by one, and the above is not restrictive and can be set according to the needs of those skilled in the art, and the above are all within the protection scope of this application.

[0045] It should also be noted that the second flow guide channel 1241 can be arranged at the bottom of the flow guide component 12, or at the side thereof. It should also be noted that the flow guide component 12 can also include only one plate, and the first flow guide channel 1211, the second flow guide channel 1241 and the fan 18 are all arranged on the plate. As long as the fan 18 can take in air into the freezer liner 10 through the first flow guide channel 1211, and the freezer liner 10 can exhaust air from the second flow guide channel 1241, all of the above are within the protection scope of the present application.

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

[0047] In one embodiment, if Figure 7 As shown, the bottom plate 123, the inner plate 121 and the guide plate 124 are integrally formed, or the bottom plate 123, the outer plate 122 and the guide plate 124 are integrally formed. This application takes the integral forming of the bottom plate 123, the outer plate 122 and the guide plate 124 as an example for introduction. The above components are integrally formed, which can reduce assembly steps, save installation time, and do not require multiple mold openings.

[0048] It should be noted that the inner plate 121 and the outer plate 122 may be connected directly or through other components. For those skilled in the art, the specific meanings of the above terms in this application may be understood according to specific circumstances.

[0049] In one embodiment, if Figures 6 to 8 As shown, the flow guide assembly 12 further includes a water receiving groove 125, which passes through the outer plate 122 and the inner plate 121 and is communicated with the external space of the refrigerator inner liner 10. The flow guide assembly 12 has not only an air guiding function, but also a water guiding function. By arranging the water receiving groove 125 on the flow guide assembly 12, when water drops exist in the refrigerator inner liner 10 or on the surface of the flow guide assembly 12, the water drops can flow downward into the water receiving groove 125 and be discharged to the outside of the refrigerator inner liner 10 by the water receiving groove 125.

[0050] In one embodiment, if Figure 8 As shown, the water receiving tank 125 is inclined from the first end to the second end, and the first end is higher than the second end, wherein the first end is the end of the water receiving tank 125 close to the inner plate 121, and the second end is the end of the water receiving tank 125 close to the outer plate 122. Figure 8 The arrow shown in the figure points to the flow direction of water in the water receiving groove 125. Since the inner plate 121 is close to the freezer inner tank 10 and the outer plate 122 is far away from the freezer inner tank 10, the first end is higher than the second end. When water falls into the water receiving groove 125, the water can flow along the first end of the water receiving groove 125 to the second end and be discharged to the outside of the freezer inner tank 10. The above arrangement can prevent water from accumulating in the freezer inner tank 10 and can also prevent water from freezing in the water receiving groove 125.

[0051] In one embodiment, if Figure 6 , Figure 7As shown, a guide plate 1212 is provided on the inner plate 121, and the guide plate 1212 is inclined from one end to the other end, and the lowest end of the guide plate 1212 is located above the water receiving groove 125, so that the liquid can flow into the water receiving groove 125 along the guide plate 1212. When water droplets condense on the inner plate 121, the water droplets will flow downward onto the guide plate 1212, and then be guided into the water receiving groove 125 by the guide plate 1212. The inclined setting of the guide plate 1212 can ensure that the water droplets can enter the water receiving groove 125 under the guidance of the guide plate 1212 under the action of gravity, thereby avoiding water accumulation on the guide assembly 12 to the greatest extent.

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

[0053] In one embodiment, if Figure 4 As shown, the refrigerator liner 10 can accommodate the storage rack 15. Figure 3 As shown, the refrigerator inner container 10 includes an avoidance step 11, on which a boss 113 is provided. The side wall 101 of the refrigerator inner container 10 is also provided with a first support member 16, on which a first overlap portion 161 is provided. Figure 4 The rack 15 shown in FIG. 1 is detachably mounted on Figure 3 In general, no items are placed on the avoidance step 11, which causes great waste of the internal space of the refrigerator inner liner 10. In order to improve the space utilization rate inside the refrigerator inner liner 10, the boss 113 is arranged on the avoidance step 11, and the shelf 15 is arranged on the boss 113 and the first overlap portion 161, thereby adding a layer of storage space, thereby improving the space utilization rate of the refrigerator inner liner 10. When the user does not need the shelf 15, the shelf 15 can be removed from the refrigerator inner liner 10.

[0054] In one embodiment, if Figure 3As shown, the boss 113 is set in a stepped shape, including a first step surface 1131 and a second step surface 1132. Along the projection perpendicular to the direction of the opening end 10a of the refrigerator liner 10, the first step surface 1131 is higher than the second step surface 1132, and one end of the rack 15 can be set on the first step surface 1131 or the second step surface 1132. The user can adjust the position of the rack 15 on the boss 113 according to the needs. Since the second guide channel 1241 and the groove 112 are located between the avoidance step 11 and the rack 15, the air outlet of the refrigerator liner 10 needs to pass between the rack 15 and the avoidance step 11. When there are many things on the rack 15, in order to ensure sufficient air outlet space, the distance between the rack 15 and the avoidance step 11 can be increased so that the rack 15 is placed on the first step surface 1131 to ensure ventilation effect.

[0055] In one embodiment, if Figure 2 As shown, the shelf 15 and one side 152 close to the inner plate 121 are overlapped on the bottom plate 123. At this time, the bottom plate 123 can play a supporting role for the shelf 15 to ensure the stability of the shelf 15 placed in the refrigerator inner tank 10.

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

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

[0058] It should be noted that a plurality of storage devices are arranged in the freezer inner tank 10, which require support from the corresponding overlapping portions on the first support member 16 and the second support member 17. This application only introduces the example of the second overlapping portion 171 and the third overlapping portion 162 supporting one layer of the storage devices. The principle of supporting the storage devices in other layers is the same as the principle of using the second overlapping portion 171 and the third overlapping portion 162 to support the storage devices, and will not be repeated here.

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

[0060] In one embodiment, if Figure 4 As shown, a drainage groove 13 is further provided at one end of the freezer inner liner 10 near the opening end 10a, and a drainage port 131 is provided in the drainage groove 13. The drainage groove 13 is inclined from its edge toward the drainage port 131, so that the water in the drainage groove 13 can flow into the drainage port 131. When there are water drops on the avoidance step 11, they can slide down along the inclined surface 111 or slide down along the groove 112 and fall into the drainage groove 13. Since the drainage groove 13 is inclined in the opposite direction to the drainage port 131, the water in the drainage groove 13 will flow toward the drainage port 131 and then flow out from the drainage port 131. The provision of the drainage groove 13 further prevents the water in the freezer inner liner 10 from freezing.

[0061] In one embodiment, if Figure 4 As shown, a plurality of protrusions 132 are provided in the drainage groove 13, and flow channels 133 are formed between adjacent protrusions 132 and between the protrusions 132 and the edge of the drainage groove 13 (for the convenience of display, Figure 4 Only the flow channel 133 formed between the adjacent protrusions 132 is marked, and the flow channel 133 is connected to the drain port 131. When water flows into the drain groove 13, it is difficult to gather the water because the drain groove 13 is large. At this time, the flow channel 133 can first gather the water, and then the water can flow into the drain port 131 through the guidance of the flow channel 133. The above arrangement can effectively guide the water in the drain groove 13 and drain it quickly.

[0062] In one embodiment, if Figure 5As shown, a shelf 14 is arranged above the drain groove 13, and a gap 142 is arranged between the shelf 14 and the drain groove 13, so that the liquid sliding down the inclined surface 111 can flow into the drain groove 13 through the gap 142. The shelf 14 on the drain groove 13 can place items, thereby further increasing the space utilization rate of the refrigerator liner 10. In addition, the gap 142 between the shelf 14 and the drain groove 13 does not affect the flow of water on the avoidance step 11 into the drain groove 13 when the shelf 14 is arranged. In addition, when the refrigerator liner 10 includes a guide assembly 12, since the guide assembly 12 is provided with a first guide channel 1211, the first guide channel 1211 can blow to the inclined surface 111 when blowing in the direction of the opening end 10a, and the water on the inclined surface 111 can slide down faster under the wind and quickly pass through the gap 142 to flow into the drain groove 13 and be discharged from the drain port 131, thereby further reducing the problem of ice formation in the refrigerator liner 10.

[0063] It should be noted that the shelf 14 can leave a gap between the shelf 14 and the drainage trough 13 through the support of the support legs 141. The support legs 141 can be set to a columnar shape or a long strip shape. The above is not restrictive and can be set according to the needs of technical personnel in this field. The above are all within the protection scope of this application.

[0064] In one embodiment, if Figure 5 As shown, the shelf 14 is also provided with a plurality of leak holes 143, which are connected to the drainage groove 13. When there are water drops on the shelf 14, the water drops can enter the drainage groove 13 from the leak holes 143, thereby ensuring that the shelf 14 can be placed with other items while avoiding the problem of water accumulation or even ice on the shelf 14.

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