[0070] Combination Figure 1 As shown, an embodiment of the present disclosure provides an inner liner assembly 10, including an inner liner 100. The inner liner 100 includes a storage space 110 with an opening, and a side wall 130 of the inner liner 100 is provided with an air supply groove 120. In the width direction of the inner liner 100, the ratio of the groove depth value of the air supply groove 120 to the width value of the inner liner 100 is in the range of 2% to 8%.

[0071] Combination Figure 1 and Figure 2 As shown, the inner liner assembly 10 provided by the embodiment of the present disclosure is used, and the air supply groove 120 is provided on the side wall 130 of the inner liner 100 to guide and deliver the cold air into the storage space 110. Along the width direction of the inner liner 100, the ratio of the groove depth value of the air supply groove 120 to the width value of the inner liner 100 is set in a range of 2% to 8%. On the premise of ensuring smooth demoulding of the inner liner 100, the ratio of the cooling effect to the power consumption (abbreviated as energy efficiency ratio) is improved, the temperature uniformity in the storage space 110 is improved, and the heat preservation effect of the storage space 110 is improved.

[0072] Combination Figure 2 As shown, the depth of the air supply slot 120 is recorded as x, in mm; the width of the inner liner 100 is recorded as y, in mm; the ratio x / y of the depth x of the air supply slot 120 to the width y of the inner liner 100 ranges from 2% to 8%.

[0073] The determination of the optimal ratio x / y of the depth value x of the air supply slot 120 and the width value y of the liner 100 can be obtained by comparing the following parameters, such as: foam layer thickness, refrigeration effect, process yield, power consumption, temperature uniformity, etc. It should be understood that: the foam layer is formed in the space between the cabinet 20 of the freezer 1 and the liner assembly 10 for heat preservation, and the thickness of the foam layer is in mm; the refrigeration effect can be the weight of the standard food frozen every 12 hours, in kg / 12h; the process yield can be the production yield of the blister-formed liner 100; the power consumption can include annual power consumption and / or standard power consumption every 24 hours, the annual power consumption is in kW·h / y, and the standard power consumption every 24 hours is kW·h / 24h; temperature uniformity refers to the temperature difference of each point in the liner 100, in °C, and multiple positions can be selected for measurement, for example, the temperature difference of a group of side walls 130 opposite to the liner 100 close to the storage space 110 can be selected for measurement.

[0074] As shown in Table 1, by measuring the parameters such as the freezing capacity, annual power consumption and standard power consumption of multiple inner pots 100 of the same volume, the optimal ratio x / y of the groove depth value x of the air supply groove 120 and the width value y of the inner pot 100 is determined. It can be seen that when the ratio of the groove depth value of the air supply groove 120 to the width value of the inner pot 100 is in the range of 2% to 8%, the weight of the standard food frozen every 12 hours reaches 10.2kg / 12h to 12.5kg / 12h, the standard power consumption every 24 hours is reduced to 0.65kW·h / 24h to 0.71kW·h / 24h, and the annual power consumption is reduced to 261kW·h / y to 284kW·h / y.

[0075] Table 1

[0076]

[0077] In the related art, when the value of the ratio x / y of the depth value x of the air supply slot 120 to the width value y of the liner 100 is greater than 8%, the width value y of the liner 100 is relatively low, which increases the length value of the liner 100 under the same volume, thereby increasing the required air supply distance of the cold air, reducing the refrigeration effect, and increasing the power consumption. When the depth value x of the air supply slot 120 is relatively high, the thickness of the foam layer outside the liner 100 is reduced due to the restriction of space, thereby reducing the insulation effect of the storage space 110, reducing the refrigeration effect, and increasing the power consumption. For example, as shown in Table 1, when the value of the ratio x / y of the depth value x of the air supply slot 120 to the width value y of the liner 100 is 11%, the weight of the standard food frozen every 12 hours is only 8.1kg / 12h, the standard power consumption every 24 hours reaches 0.75kW·h / 24h, and the annual power consumption reaches 297kW·h / y. In addition, when the ratio x / y of the depth x of the air supply slot 120 to the width y of the liner 100 is high, the mold is difficult to remove, which reduces the process yield of the liner 100 formed by vacuum molding.

[0078] In the related art, when the value of the ratio x / y of the depth value x of the air supply slot 120 to the width value y of the liner 100 is less than 2%, the depth value x of the air supply slot 120 is low, the air supply capacity of the air supply slot 120 decreases, and the width value y of the liner 100 is high, which increases the required air supply distance of the cold air, reduces the refrigeration effect, and increases the power consumption. For example, as shown in Table 1, when the value of the ratio x / y of the depth value x of the air supply slot 120 to the width value y of the liner 100 is 0.5%, the weight of the standard food frozen every 12 hours is only 7.9kg / 12h, the standard power consumption every 24 hours reaches 0.76kW·h / 24h, and the annual power consumption reaches 301kW·h / y.

[0079] Exemplarily, the ratio of the depth of the air supply slot 120 to the width of the inner tank 100 may be 2%, 3%, 4%, 4.5%, 5%, 5.5%, 6%, 7%, 8%, etc.

[0080] Optionally, combined Figure 1 and Figure 2 As shown, along the width direction of the inner container 100, the ratio of the groove depth value of the air supply groove 120 to the width value of the inner container 100 ranges from 4% to 6%.

[0081] In this embodiment, along the width direction of the inner liner 100, the ratio of the groove depth value of the air supply groove 120 to the width value of the inner liner 100 is set in the range of 4% to 6%. Under the premise of ensuring smooth demolding of the inner liner 100, the energy efficiency ratio is further improved, the temperature uniformity in the storage space 110 is further improved, and the thermal insulation effect of the storage space 110 is further improved.

[0082] Combined with Table 1, it can be seen that when the ratio of the depth of the air supply groove 120 to the width of the inner tank 100 is in the range of 4% to 6%, the weight of the standard food frozen every 12 hours reaches 11.7kg / 12h to 12.5kg / 12h, the standard power consumption every 24 hours is reduced to 0.65kW·h / 24h to 0.68kW·h / 24h, and the annual power consumption is reduced to 261kW·h / y to 272kW·h / y.

[0083] Combination Figure 2 As shown, the depth of the air supply slot 120 is recorded as x, in mm; the width of the inner liner 100 is recorded as y, in mm; the ratio x / y of the depth of the air supply slot 120 to the width of the inner liner 100 ranges from 4% to 6%.

[0084] Exemplarily, the ratio of the depth of the air supply slot 120 to the width of the inner container 100 may be 4%, 4.5%, 5%, 5.5%, 6%, etc.

[0085] Optionally, the ratio of the slot area of ​​the air supply slot 120 to the side wall area where the air supply slot 120 is located ranges from 10% to 50%.

[0086] In this embodiment, by reasonably setting the proportional relationship between the slot area of ​​the air supply slot 120 and the side wall area where the air supply slot 120 is located, specifically, the ratio range of the slot area of ​​the air supply slot 120 to the side wall area where the air supply slot 120 is located is 10% to 50%, so as to meet the cooling demand of the storage space 110, improve the rationality of the cold amount input into the storage space 110, thereby improving the cooling efficiency, and can improve the convenience of processing the air supply slot 120.

[0087] Optionally, the ratio of the slot area of ​​the air supply slot 120 to the side wall area where the air supply slot 120 is located ranges from 15% to 40%.

[0088] In this embodiment, when the ratio of the notch area of ​​the air supply slot 120 to the side wall area where the air supply slot 120 is located is less than 15%, the air supply area is reduced, affecting the temperature uniformity in the inner tank, resulting in poor freezing capacity. When the ratio of the notch area of ​​the air supply slot 120 to the side wall area where the air supply slot 120 is located is greater than 40%: on the one hand, when the inner tank is a sheet metal part, the air duct and the cover plate area are large, resulting in a higher cost; on the other hand, when the inner tank is an adsorption molded part, the air supply slot area is large and difficult to mold, resulting in a lower yield rate, a larger air duct cover plate area, and a higher cost. By reasonably setting the proportional relationship between the notch area of ​​the air supply slot 120 and the side wall area where the air supply slot 120 is located, the rationality of the cold input into the storage space 110 is improved, thereby improving the refrigeration efficiency.

[0089] Optionally, a ratio of a slot area of ​​the air supply slot 120 to an area of ​​a side wall where the air supply slot 120 is located includes 15%, 20%, 25%, 30%, 35% or 40%.

[0090] Optionally, the angle between the depth direction of the air supply slot 120 and the depth direction of the storage space 110 ranges from 87° to 93°.

[0091] In this embodiment, when the angle between the depth direction of the air supply slot 120 and the depth direction of the storage space 110 is less than 87° or greater than 93°, the air supply distance will be longer, and the wind resistance will increase, resulting in poor refrigeration capacity. The present application further improves the efficiency of cold air transmission by setting the angle between the depth direction of the air supply slot 120 and the depth direction of the storage space 110 to 87° to 93°.

[0092] Optionally, specific values ​​of the angle between the depth direction of the air supply slot 120 and the depth direction of the storage space 110 include: 87°, 89°, 90°, 92° or 93°.

[0093] Optionally, combined Figures 10 to 22 As shown, the liner 100 includes a plurality of side walls 130 and a bottom wall 132. The plurality of side walls 130 are connected end to end in sequence. The bottom wall 132 is connected to the plurality of side walls 130, and the plurality of side walls 130 and the bottom wall 132 enclose a storage space 110. The bottom wall 132 includes a first bottom 1322 and a step portion 1324 connected to each other, and the step portion 1324 includes a supporting surface 150.

[0094] In this embodiment, a plurality of side walls 130 connected in sequence are arranged around the bottom wall 132 to form a storage space 110. The bottom wall 132 of the liner 100 is provided with a first bottom 1322 and a step portion 1324. The step portion 1324 is used to support the evaporator 210 and is located to provide space for the installation of the evaporator 210, thereby improving the compactness of the structural arrangement of each component and improving the utilization rate of the storage space 110.

In the case where the evaporator 210 is provided on the step portion 1324, and the height of the step portion 1324 is higher than the first bottom portion 1322, that is, the evaporator 210 is placed higher relative to the height of the inner tank 100. There are many embodiments for the location of the drain port 140, including but not limited to: the drain port 140 is provided on the supporting surface 150; or the drain port 140 is provided at the connection between the supporting surface 150 and the side wall 130; or the drain port 140 is provided at the connection between the supporting surface 150 and the first bottom portion 1322. The location of the drain port 140 can be selected and provided according to the specific structure of the refrigerator.

[0098] In some embodiments, in combination Fig.10 As shown, the drain port 140 is provided on the supporting surface 150. The drain port 140 is provided on the supporting surface 150 to discharge the condensed water or defrosted water of the evaporator 210 through the drain port 140. The drain port 140 is provided on the supporting surface 150 for easy operation. Furthermore, a guide surface is provided on the supporting surface 150 on the peripheral side of the drain port 140, and the guide surface is relatively inclined to guide the condensed water or defrosted water of the supporting surface 150 to the drain port 140, thereby improving the smoothness of drainage.

[0099] In some embodiments, in combination Fig.12 , Fig.13 and Fig.15 As shown, the drain port 140 is provided at the connection between the supporting surface 150 and the side wall 130. The drain port 140 is provided at the connection between the side wall 130 and the supporting surface 150 on the peripheral side of the supporting surface 150 for drainage. Further, the supporting surface 150 includes a groove-shaped guide groove, and the end of the guide groove extends to the drain port 140 to improve the diversion effect and drainage efficiency of condensed water or defrosting water.

[0100] Specifically, combined Fig.12 and Fig.15 As shown, the drain port 140 is disposed at the connection between the supporting surface 150 and one side wall 130.

[0101] In some embodiments, in combination Fig.11As shown, the drain port 140 is provided at the connection between the supporting surface 150 and the first bottom 1322. A vertical surface connecting the supporting surface 150 and the first bottom 1322 is provided between the step portion 1324 and the first bottom 1322. The drain port 140 is provided at the connection between the vertical surface and the supporting surface 150 for drainage.

[0104] In this embodiment, when L is greater than 0.7H, in order to leave enough height for setting the air supply slot 120, the height of the inner liner 100 needs to be increased, which results in the inner liner 100 being too high, which is not conducive to users bending over to take and put items. In addition, the evaporator 210 cavity is located at the bottom, and the cold air in the refrigerator sinks, which will cause the airflow temperature below the refrigerator to be lower and the temperature above to be higher, resulting in uneven temperature in the refrigerator, affecting the cooling effect.

[0105] When L is greater than 0.1H, it can ensure that the evaporation bin 200 does not reach the cabinet opening, which not only reserves the installation space at the cabinet opening, but also prevents the evaporation bin 200 from being too close to the cabinet opening, causing severe frost and affecting the use of the refrigerator. In addition, by setting the value range of L to: 0.1H≤L≤0.7H, the height of the refrigerator liner 100 can also adapt to the height of the human body, improving the convenience of users taking things.

[0106] Optionally, the distance L between the upper edge of the air supply slot 120 and the plane where the drain outlet 140 is located includes: 0.1H, 0.3H, 0.5H or 0.7H.

[0118] In some embodiments, in combination Fig.17 As shown, the drain port 140 is disposed at the connection between the supporting surface 150 and the vertical surface of the second bottom 1326 and the side wall 130 .

[0119] In some embodiments, in combination Fig.19 As shown, the drain port 140 is disposed at the connection between the supporting surface 150 , the vertical surface of the first bottom 1322 , and the side wall 130 .

[0120] Optionally, the inner tank 100 further includes a drain port 140 , and a distance L between an upper edge of the air supply slot 120 and a plane where the drain port 140 is located has a value range of: 0.3H≤L≤1.2H, where H is a height of the inner tank 100 .

[0121] In this embodiment, when L is less than 0.3H, in order to leave sufficient height for setting the air supply slot 120, the height of the step will be higher, resulting in a reduction in the effective volume, which is not conducive to users storing items.

[0122] When L is greater than 1.2H, the bottom foam layer will be too thin, the refrigerator will have poor thermal insulation performance, and the energy consumption will be high; and when L is greater than 1.2H, the drain outlet 140 will be located lower and the drainage angle will be smaller, which is not conducive to drainage.

[0125] In some embodiments, there are multiple air supply slots 120. The air supply slots 120 include a first air supply slot 121 and a second air supply slot 122. Along the height direction of the inner tank, the first air supply slot 121 is located above the second air supply slot 122. The distance L between the upper edge of the first air supply slot 121 located on the opening side of the inner tank and the plane where the drain port 140 is located is in the range of 0.3H≤L≤1.2H, where H is the height of the inner tank 100, so as to improve the cooling efficiency and ensure smooth drainage.

[0127] In this embodiment, a support frame is provided in the inner tank 100, and the support frame is used to carry the evaporator 210, so as to improve the installation position of the evaporator 210. Moreover, by providing the support frame, the structural complexity of the inner tank 100 is reduced, and the production difficulty of the inner tank 100 is reduced.

[0128] Optionally, combined Figure 3 As shown, the air supply slot 120 includes: a first air supply slot 121, located on the side wall 130 of the inner liner 100; wherein the distance h1 between the upper edge of the first air supply slot 121 and the bottom wall 132 of the inner liner 100 is in the range of 0.7H≤h1≤0.95H, and H is the height of the inner liner 100.

[0129] In this embodiment, a first air supply slot 121 for delivering cold air to the storage space 110 is provided on the side wall 130 of the inner liner 100. By setting the distance h1 between the upper edge of the first air supply slot 121 and the bottom wall 132 of the inner liner 100 to a range of 0.7H≤h1≤0.95H, the cooling rate of the storage space 110 is increased, the power consumption is reduced, and the uniformity in the storage space 110 is improved.

[0130] Optionally, combined Figure 3 As shown, the air supply slot 120 also includes: a second air supply slot 122, located on the side wall 130 of the inner liner 100 and below the first air supply slot 121; wherein the distance h2 between the lower edge of the second air supply slot 122 and the bottom wall 132 of the inner liner 100 is in the range of 0.05H≤h2≤0.3H.

[0131] In this embodiment, a first air supply groove 121 and a second air supply groove 122 are provided on a single side wall 130 of the inner liner 100, and along the height direction of the inner liner 100. The first air supply groove 121 is located above the second air supply groove 122. By arranging two air supply grooves at intervals on the side wall 130 of the inner liner 100, the temperature balance in the storage space 110 is improved. Furthermore, by setting the range of the distance h1 between the upper edge of the first air supply groove 121 and the bottom wall 132 of the inner liner 100 to 0.7H≤h1≤0.95H, and the range of the distance h2 between the lower edge of the second air supply groove 122 and the bottom wall 132 of the inner liner 100 to 0.05H≤h2≤0.3H. In this way, the refrigeration efficiency of reaching the target refrigeration temperature in the storage space 110 can be improved, the refrigeration time can be shortened, and the power consumption can be reduced.

[0132] Specifically, taking the same target cooling temperature as an example, using the embodiment provided in the present application, the distance h1 between the upper edge of the first air supply groove 121 and the bottom wall 132 of the inner liner 100 is set in the range of 0.7H≤h1≤0.95H, and the distance h2 between the lower edge of the second air supply groove 122 and the bottom wall 132 of the inner liner 100 is set in the range of 0.05H≤h2≤0.3H, so that the refrigeration time required to reach the target refrigeration temperature in the storage space 110 is within 90 minutes, the power consumption is less than 1.19kW·h / 24h, and the temperature difference between the upper temperature and the lower temperature of the storage space 110 can be controlled within 5°C, the temperature distribution in the storage space 110 is uniform, the refrigeration efficiency is high, and the energy consumption is low.

[0133] However, when the value of h1 is within the range of less than 0.7H or greater than 0.95H and the value of h2 is within the range of less than 0.05H or greater than 0.93H, the refrigeration time required to achieve the target refrigeration temperature in the storage space 110 is within 115min to 230min, the power consumption is greater than 1.35kW·h / 24h, and the temperature difference between the upper and lower temperatures of the storage space 110 is between 7°C and 15°C. The temperature difference between the upper and lower parts of the storage space 110 is large, the refrigeration efficiency is slow, and the energy consumption is high.

[0134] Optionally, specific values ​​of the distance h1 between the upper edge of the first air supply slot 121 and the bottom wall 132 of the inner container 100 include: 0.7H, 0.8H, 0.9H or 0.95H.

[0135] Optionally, a specific value of a distance h2 between a lower edge of the second air supply slot 122 and a bottom wall 132 of the inner container 100 includes: 0.05H, 0.1H, 0.2H or 0.3H.

[0136] Optionally, combined Figure 1 and Figure 2 As shown, the inner liner 100 includes an open end connected to the storage space 110; along the depth direction of the inner liner 100, the value range of the distance l between the groove wall of the air supply groove 120 located at the open end of the inner liner 100 and the plane where the open end is located satisfies: l≥15mm.

[0137] In this embodiment, the depth direction of the air supply groove 120 is perpendicular to the demolding direction of the inner liner 100. By increasing the distance l between the groove wall of the air supply groove 120 located at the open end of the inner liner 100 and the plane where the open end is located, the demolding process yield of the inner liner assembly 10 is improved.

[0138] Exemplarily, the distance l between the groove wall of the air supply groove 120 located at the open end of the inner liner 100 and the plane where the open end is located can be 15 mm, 15.5 mm, 16 mm, 16.5 mm, 17 mm, etc.

[0139] Optionally, the distance l between the groove wall of the air supply groove 120 at the open end of the inner tank 100 and the plane where the open end is located satisfies the range of: 0.3H≥l≥15mm, so that the air supply grooves are reasonably arranged according to the size of the inner tank to improve the cooling efficiency.

[0140] Optionally, combined Figure 1 As shown, the side wall 130 of the inner liner 100 is provided with a reinforcing rib 124, and the reinforcing rib 124 is located at the bottom wall of the air supply slot 120, wherein the extension direction of the reinforcing rib 124 is the same as the extension direction of the air supply slot 120, and / or the number of the reinforcing rib 124 is multiple, and the multiple reinforcing ribs 124 are spaced apart along the extension direction of the air supply slot 120.

[0141] In this embodiment, the side wall 130 of the liner 100 is provided with a reinforcing rib 124, which is located at the bottom wall of the air supply slot 120, and the reinforcing rib 124 strengthens the structural stability of the air supply slot 120. The cold air is transported along the extension direction of the air supply slot 120, and the extension direction of the reinforcing rib 124 is the same as the extension direction of the air supply slot 120, which plays a role in guiding the cold air. There are multiple reinforcing ribs 124, which are distributed at intervals along the extension direction of the air supply slot 120, thereby improving the structural stability of each location in the extension direction of the air supply slot 120 and improving the overall structural stability of the air supply slot 120.

[0142] Optionally, the reinforcing rib 124 is formed by adsorption of the side wall 130 of the liner 100. The reinforcing rib 124 is located at the bottom wall of the air supply slot 120, and the reinforcing rib 124 strengthens the structural stability of the air supply slot 120 and reduces the probability of damage to the air supply slot 120 during demoulding.

[0143] Optionally, the air supply slots 120 are located on at least two side walls 130 of the two groups of side walls 130, so that air can be supplied to multiple walls in the refrigerator 1 at the same time. The air supply from multiple walls increases the amount of cold air entering the refrigerator 1, which is suitable for situations where the storage space 110 has a large volume, a large storage capacity, and a large amount of cold air is required.

[0144] Optionally, combined Figure 1 As shown, the air supply slot 120 of the side wall 130 located on one side of the inner container 100 further includes: a connecting slot 123, and both ends of the connecting slot 123 are respectively connected to the first air supply slot 121 and the second air supply slot 122 on both sides.

[0145] In this embodiment, a first air supply groove 121 is provided on the side of the inner liner 100 facing the open end of the inner liner 100 and a second air supply groove 122 is provided below the first air supply groove 121 along the depth direction of the inner liner 100. Both ends of the connecting groove 123 are respectively connected with the first air supply groove 121 and the second air supply groove 122 on both sides. The connecting groove 123 distributes cold air to the first air supply groove 121 and the second air supply groove 122. The first air supply groove 121 guides the cold air entering from the connecting groove 123 to the middle and upper part of the storage space 110, and the second air supply groove 122 guides the cold air entering from the connecting groove 123 to the middle and lower part of the storage space 110, thereby lowering the temperature in the storage space 110, transporting cold air to the storage space 110 from different depths of the inner liner 100, and improving the temperature uniformity in the storage space 110.

[0146] Optionally, combined Figure 1 and Figure 4As shown, on the plane of the side wall 130, the cross-sectional area of ​​the first air supply slot 121 is larger than the cross-sectional area of ​​the second air supply slot 122. Cold air tends to sink because its density is greater than that of air, and the first air supply slot 121 is located on the opening side, and is affected by the opening of the door body 30, so the cold air consumption is large. Therefore, the cross-sectional area of ​​the first air supply slot 121 is set to be larger than the cross-sectional area of ​​the second air supply slot 122, so as to increase the cold air output of the first air supply slot 121 and improve the temperature uniformity in the storage space 110.

[0147] Optionally, combined Figure 1 and Figure 3 As shown, the first air supply slot 121 includes an expansion structure 1211, and the expansion structure 1211 is connected to one end of the connection slot 123. The expansion structure 1211 increases the cold air output of the first air supply slot 121, thereby improving the temperature uniformity in the storage space 110.

[0148] Optionally, combined Figure 1 and Figure 3 As shown, the connecting slot 123 includes a fan slot 1231, and the fan slot 1231 is used to install the air supply fan 220. The air supply fan 220 can simultaneously transport cold air to the first air supply slot 121 and the second air supply slot 122.

[0149] Optionally, the inner liner assembly 10 further includes an embedded component installation portion. The embedded component installation portion is used to install an air supply duct embedded component; wherein the air supply duct embedded component and the inner liner 100 enclose an air supply duct 120 .

[0150] In this embodiment, the embedded part installation part is used to install the embedded part of the air supply duct, so that the embedded part of the air supply duct and the inner liner 100 enclose the air supply duct 120. Since the air supply duct cannot be formed integrally with the sheet metal inner liner, the embedded part installation part can be applied to the inner liner made of sheet metal to facilitate the installation of the embedded part of the air supply duct. In addition, compared with the air duct formed by adsorption, by installing the embedded part of the air supply duct, the adsorption area is reduced, thereby reducing adsorption defects, facilitating the processing of the inner liner, and not easy to deform.

[0151] Optionally, at least one of the first air supply slot 121 and the second air supply slot 122 uses an air supply duct embedded part to improve the adaptability of the inner tank.

[0152] Optionally, the air supply slot 120 is formed by adsorption of the side wall 130 of the inner container 100 .

[0153] In this embodiment, the air supply groove 120 is formed by vacuum forming on the side wall 130 of the inner liner 100, which reduces the process of installing the air supply duct on the inner liner 100 and improves the process production efficiency. Since there is no need to install the air supply duct and the air duct embedded component structure is reduced on the inner liner 100, the manufacturing cost is reduced.

[0154] Combination Figure 1 , Figure 4 and Figure 5 As shown, the embodiment of the present disclosure provides a process for the vacuum forming of an inner liner, which is used for the inner liner component 10 as described in any of the aforementioned embodiments, and the process includes: placing a plastic sheet on a mold 2; wherein the side of the mold 2 includes a core pulling mechanism; heating the plastic sheet to a softened state and then blowing bubbles; extracting the air between the mold 2 and the plastic sheet to form an inner liner 100; starting the core pulling mechanism 40, and the mold 2 slides out of the air supply slot 120 of the inner liner 100; and demolding.

[0155] Combination Figure 4 As shown, it is a process flow chart for liner blister forming provided by an embodiment of the present disclosure. The process of this embodiment includes:

[0156] S101, placing a plastic sheet on a mold; wherein the side of the mold includes a core pulling mechanism;

[0157] S102, heating the plastic sheet to a softened state and then blowing bubbles;

[0158] S103, extracting air between the mold and the plastic sheet to form an inner container;

[0159] S104, the core pulling mechanism is started, and the mold slides out from the air supply slot of the inner liner;

[0160] S105, demoulding.

[0161] The process for the liner vacuum forming provided by the embodiment of the present disclosure heats the plastic sheet to soften the plastic sheet and put it into a flowing state, and then blows bubbles to improve the degree of fit between the plastic sheet and the mold 2, so that secondary stretching is generated when the air between the mold 2 and the plastic sheet is extracted due to the low degree of fit, thereby improving the quality of the liner 100. The core pulling mechanism 40 is provided on the side of the mold 2, and the mold 2 is slid out of the air supply slot 120 of the liner 100, thereby ensuring that the mold 2 can be demolded smoothly.

The inner tank assembly 10 is arranged in the cabinet body 20, and an evaporation bin 200 is arranged on the inner tank 100, and the evaporation bin 200 is connected to the air supply slot 120. The evaporator 210 is arranged in the evaporation bin 200.

[0174] The cold cabinet 1 provided in the present disclosure includes an inner tank assembly 10, a cabinet body 20 and an evaporator 210 as described in any of the above embodiments. The inner tank assembly 10 is arranged on the cabinet body 20, and an evaporation bin 200 is arranged on the inner tank 100, and the evaporation bin 200 is connected to the air supply groove 120. The evaporator 210 is arranged in the evaporation bin 200. The inner tank assembly 10 includes an inner tank 100. The inner tank 100 includes a storage space 110 with an opening, and the side wall 130 of the inner tank 100 is formed with an air supply groove 120 by vacuum molding. Among them, the depth direction of the air supply groove 120 is perpendicular to the depth direction of the storage space 110. By arranging the air supply groove 120 on the side wall 130 of the inner tank 100, the cold air is guided and transported into the storage space 110. The depth direction of the air supply groove 120 is perpendicular to the depth direction of the storage space 110, which further improves the efficiency of cold air transmission. The air supply groove 120 is formed by vacuum forming on the side wall 130 of the inner liner 100, which reduces the process of installing the air supply duct on the inner liner 100 and improves the process production efficiency. Since there is no need to install the air supply duct and the air duct embedded parts structure is reduced on the inner liner 100, the manufacturing cost is reduced. The refrigerator 1 provided by the present disclosure includes the inner liner assembly 10 of the aforementioned embodiment, and has all the technical effects of the aforementioned embodiment. In addition, the evaporation bin 200 is enclosed inside to define the placement space of the evaporator 210. The evaporator 210 is arranged in the placement space in the evaporation bin 200. The evaporation bin 200 is connected to the air supply groove 120, so that the cold air in the evaporator 210 is transported to the air supply groove 120.

[0175] Optionally, combined Figure 7 As shown, the evaporation chamber 200 includes an evaporator cover plate 250. The evaporator cover plate 250 and the inner container 100 are enclosed to form the evaporation chamber 200.

[0176] Optionally, combined Figure 7 As shown, the evaporator cover plate 250 includes an extension section 251. The extension section 251 of the evaporator cover plate 250 is connected to the air supply slot 120, and is used to provide an installation space for the air supply fan 220.

[0177] Optionally, combined Figure 6 and Figure 7 As shown, the evaporator cover 250 includes one or more return air ports 260. The return air ports 260 guide the air in the storage space 110 into the evaporation bin 200, and the air in the evaporation bin 200 exchanges heat with the evaporator 210. The refrigerant absorbs heat and evaporates to cool the air, converting the air into cold air. The cold air enters the air supply slot 120, and is guided into the storage space 110 of the inner liner 100 through the air supply slot 120, thereby reducing the temperature of the food in the storage space 110. After exchanging heat with the food, the cold air becomes air with a higher temperature, and the air enters the return air ports 260 again. This process is called an air cooling cycle, which can recycle the air and improve the utilization efficiency of the air in the refrigerator 1.

[0178] Optionally, combined Figure 6 and Figure 7 As shown, the multiple return air vents 260 include multiple upper return air vents 261 opened along the length direction of the inner liner 100 and multiple side return air vents 262 opened along the depth direction of the inner liner 100. The multiple directions of return air increase the return air volume in the refrigerator 1, improve the efficiency of air circulation, and improve the refrigeration effect.

[0179] Optionally, combined Figure 6 and Figure 7 As shown, an air supply cover plate 230 is provided on the side wall 130 of the inner liner 100. The air supply cover plate 230 is provided on the side of the air supply slot 120 facing the storage space 110, and the air supply cover plate 230 and the air supply slot 120 form an air supply duct, and an air supply port 231 is provided on the air supply cover plate 230, and cold air enters the storage space 110 through the air supply port 231. The air supply cover plate 230 can prevent the items in the refrigerator 1 from entering the air supply slot 120, causing the air supply slot 120 to be blocked.

[0180] Optionally, combined Figure 6 and Figure 7 As shown, the air supply cover plate 230 can be combined with the side wall 130 of the inner container 100 by welding, snapping or screw locking, but it is not limited to this.

[0181] Optionally, an air supply grille is provided at the air supply port 231 of the air supply cover 230. In practice, when there are many items in a certain direction, an air supply grille can be provided at the air supply port 231 of the air supply cover 230, and the grille blades of the air supply grille face the direction, thereby facilitating uniform cooling of the food in the storage space 110.

[0182] Optionally, combined Fig. 9 As shown, the evaporator 210 includes a plurality of evaporation fins 213. The evaporation fins 213 are vertically spaced and parallel to each other. Air flows between the parallel evaporation fins 213 to perform heat exchange.

[0183] In a specific embodiment, the evaporation fins 213 are arranged at intervals in the length direction of the inner liner 100 and extend in the width direction of the inner liner 100 .

[0184] Optionally, combined Fig. 9 As shown, the evaporator 210 further includes a heat exchange tube 214, and the heat exchange tube 214 is reciprocatedly penetrated through the plurality of evaporating fins 213. The refrigerant evaporates in the heat exchange tube 214 of the evaporator 210, taking away the heat of the gas.

[0185] Optionally, combined Fig. 9As shown, the evaporator 210 further includes a heating tube 215, which is reciprocatedly arranged in the plurality of evaporating fins 213. The heating tube 215 is used for heating to facilitate defrosting of the evaporator 210.

[0186] Optionally, a drain port is provided on the bottom plate of the evaporation bin 200. The refrigerator 1 circulates the air in the refrigerator 1 and flows through the evaporator 210, and the water contained in the food in the storage space 110 easily turns into water vapor at low temperature, and then adheres to the evaporator 210. The drain port is provided on the bottom plate of the evaporation bin 200, so that the condensation or defrost water on the surface of the evaporator 210 can be discharged through the drain port.

[0187] Optionally, combined Figure 1 and Figure 6 As shown, the refrigerator 1 further includes a door body 30, which is openably and closably mounted on the cabinet body 20. By opening the door body 30, food in the storage space 110 in the inner container 100 of the refrigerator 1 can be taken out.

[0188] Optionally, combined Figure 8 and Fig. 9 As shown, the cold cabinet 1 further includes an air supply fan 220 and a heat recovery component 240. The air supply fan 220 is connected to the evaporation chamber 200 and the air supply slot 120. The heat recovery component 240 is arranged on a side of the evaporator 210 close to the air supply fan 220.

[0189] In the related art, the heat recovery component 240 is arranged on the side of the evaporator 210 close to the return air port 260. Since the humidity and temperature are higher on the return air side of the evaporator 210, the refrigerant temperature in the heat recovery component 240 is lower, and the heat recovery component 240 is prone to frost and ice.

[0190] In this embodiment, under the action of the evaporator 210, the humidity and temperature of the air decrease after passing through the evaporator 210. Therefore, the air humidity and air temperature on the side of the evaporator 210 close to the supply fan 220 are lower than the air humidity and air temperature on the side of the evaporator 210 close to the return air port 260. The supply fan 220 drives the cold air in the evaporation bin 200 into the supply slot 120, thereby accelerating the air flow on the side of the supply fan 220. By arranging the heat recovery component 240 on the side of the evaporator 210 close to the supply fan 220, frost and ice are reduced, thereby improving the cooling effect.

[0191] Optionally, combined Figure 1 and Figure 6 As shown, the bottom of the inner tank 100 protrudes upward to form a step portion 1324, and the bottom space between the step portion 1324 and the cabinet 20 is used to place the compressor and the condenser, and the compressor and the condenser are connected through an exhaust pipe.

[0192] Optionally, combined Fig. 9As shown, the heat recovery component 240 includes a return air pipe and a capillary tube. One end of the return air pipe is arranged at the outlet of the evaporator 210, and the other end is arranged at the inlet of the compressor. One end of the capillary tube is arranged at the inlet of the evaporator 210, and the other end is arranged at the outlet of the compressor. In this way, the heat recovery component 240 realizes the flow circuit of the refrigerant in the evaporator 210. The refrigerant flowing out of the condenser flows into the evaporator 210 through the capillary tube, and after evaporation in the evaporator 210, it flows into the compressor through the return air pipe. The compressor compresses the refrigerant into a high-temperature and high-pressure gas and then flows into the condenser through the exhaust pipe, so that the capillary tube and the return air pipe realize the flow circuit of the refrigerant in the evaporator 210.

[0193] Furthermore, the capillary tube and the return air pipe are in contact with each other to allow heat exchange between the two, thereby further cooling the refrigerant in the capillary tube, increasing its supercooling degree, and increasing the cooling capacity of the evaporator 210.

[0194] Specifically, the heat recovery component 240 can be arranged on the evaporator 210 by copper tube connection or aluminum tube connection, and the connection method includes but is not limited to: welding, screw connection and the like.

[0195] Optionally, combined Fig. 9 As shown, the heat recovery assembly 240 further includes a tube storage box 241. The tube storage box 241 is disposed at the heat recovery assembly 240 mounting portion 125 of the inner tank 100, and is used to store and release the pipes of the heat recovery assembly 240. When installing the heat recovery assembly 240, the return air pipe and the capillary tube of the heat recovery assembly 240 are pulled out of the tube storage box 241 and then installed on the evaporator 210.

[0196] Optionally, combined Figure 6 and Figure 8 As shown, the refrigerator 1 further includes a weak current component 211 and a strong current component 212. The weak current component 211 is arranged on one side of the evaporator 210. The strong current component 212 is arranged on the other side of the evaporator 210. The weak current component 211 and the strong current component 212 are located on opposite sides of the evaporator 210.

[0197] In this embodiment, by arranging the weak-current component 211 and the strong-current component 212 on opposite sides of the evaporator 210, the electromagnetic interference of the strong-current component 212 on the weak-current component 211 is reduced, the stability of the circuit is improved, the electrical control safety of the refrigerator 1 is increased, and the performance of the refrigeration equipment is guaranteed.
