Detailed Embodiments

[0028] The following will describe in detail the specific embodiments of the present disclosure with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present disclosure, and are not intended to limit the present disclosure.

[0029] In the present disclosure, unless otherwise stated, the orientation terms such as "upper and lower" are defined based on the gravity direction of the refrigerator. Among them, the up - down direction can refer to the Z - direction in Figure 3 and the side pointed by the arrow is defined as the upper side, and the opposite side is the lower side. The length direction of the air duct plate can refer to the Z - direction in Figure 3 the width direction of the air duct plate can refer to the X - direction in Figure 3 and the thickness direction of the air duct plate can refer to the Y - direction in Figure 3 "Inner and outer" refer to the inside and outside of the contour of each component. The terms "first and second" are used to distinguish one element from another, and do not have an order or importance. In addition, in the following description when referring to the accompanying drawings, the same reference numerals in different drawings represent the same or similar elements, and the present disclosure will not repeat this.

[0030] According to some embodiments of the present disclosure, a refrigerator is provided. As shown in Figures 1 to 4 , the refrigerator includes an inner liner 1, an air duct plate 2 disposed inside the inner liner 1, and a temperature sensor 3. The air duct plate 2 is provided with a first air inlet 21 and a second air inlet 22 that communicate with the inner cavity 11 of the inner liner 1. The temperature sensor 3 is disposed at the first air inlet 21, and the first air inlet 21 and the second air inlet 22 are connected through an air guiding channel 23.

[0031] Through the above technical solution, in the refrigerator provided by the present disclosure, a part of the cold air in the inner cavity 11 can flow to the first air inlet 21; another part of the cold air in the inner cavity 11 can flow to the second air inlet 22 and flow to the first air inlet 21 through the air guide channel 23. In this way, the above two parts of cold air will convect at the first air inlet 21. Therefore, the cold air circulation effect at the first air inlet 21 can be improved. Since the temperature sensor 3 is arranged at the first air inlet 21, the above setting can improve the temperature sensing sensitivity of the temperature sensor 3. That is, the refrigerator of the present disclosure can solve the technical problem of poor temperature sensing sensitivity of the temperature sensor 3 and avoid frequent start and stop of components in the refrigerator, such as the fan. In this way, the power consumption of the refrigerator can also be reduced.

[0032] It should be noted that the present disclosure does not impose too many restrictions on the structure, shape and installation position of the air guide channel 23, which will be introduced in detail in the following embodiments. In addition, the refrigerator of the present disclosure can be configured as an air-cooled refrigerator, such as an air-cooled dual-system refrigerator. The dual-system refrigerator means that both the refrigerating chamber and the freezing chamber are equipped with refrigeration components, which can include components such as a fan and an evaporator. The present disclosure does not impose too many restrictions on this. The fan can send cold air into the following air supply channel 26. Among them, the inner cavity 11 of the above-mentioned cabinet liner 1 can be configured as a refrigerating chamber.

[0033] In some embodiments of the present disclosure, refer to Figure 3 and Figure 4As shown in the figure, the air guiding channel 23 may include: a first air guiding groove 231 that penetrates through the air duct plate 2 along the thickness direction of the air duct plate 2, and the first air guiding groove 231 communicates with the first air inlet 21. In this way, a part of the cold air in the inner cavity 11 can flow to the first air inlet 21 and enter the first air guiding groove 231; and a second air guiding groove 232 located on the back side of the air duct plate 2, and the second air guiding groove 232 communicates with the first air guiding groove 231 and the second air inlet 22. In this way, another part of the cold air in the inner cavity 11 can flow into the second air guiding groove 232 through the second air inlet 22. At this time, this part of the cold air can flow to the back of the air duct plate 2 and can continue to flow into the first air guiding groove 231. In this way, the above two parts of cold air can convect in the first air guiding groove 231. Among them, the temperature sensor 3 can be accommodated in the first air guiding groove 231. In addition, compared with setting the groove depth of the first air guiding groove 231 to be less than the thickness of the air duct plate 2, setting the first air guiding groove 231 to penetrate through the air duct plate 2 can increase the groove depth of the first air guiding groove 231, thereby increasing the volume of the first air guiding groove 231. Thus, the above two parts of cold air can convect in the first air guiding groove 231. Since the volume of the first air guiding groove 231 is increased, the convection space of the above two parts of cold air is increased, which can further improve the cold air circulation effect at the first air inlet 21. Thus, the temperature sensing sensitivity of the temperature sensor 3 can be further improved. Among them, in some embodiments, the thickness of the air duct plate 2 can be 26 mm to 28 mm, such as 27 mm. Correspondingly, the groove depth of the first air guiding groove 231 can be 26 mm to 28 mm, such as 27 mm. The present disclosure does not limit this too much.

[0034] In some embodiments of the present disclosure, with reference to Figure 3 As shown in the figure, the first air guiding groove 231 may have a height in the length direction of the air duct plate 2, and the height of the first air guiding groove 231 is 80 mm to 110 mm. Here, the height of the first air guiding groove 231 can be 90 mm, 100 mm, etc. The present disclosure does not limit this too much. In some embodiments, the length direction of the air duct plate 2 may be arranged in the up-down direction of the refrigerator.

[0035] In some embodiments of the present disclosure, with reference to Figure 3 As shown in the figure, the first air guiding groove 231 may have a width in the width direction of the air duct plate 2, and the width of the first air guiding groove 231 is 28 mm to 34 mm. Here, the width of the first air guiding groove 231 can be 30 mm, 32 mm, etc. The present disclosure does not limit this too much.

[0036] In some embodiments of the present disclosure, with reference to Figure 3 and Figure 4As shown, the air duct plate 2 may include a side wall surface 24 and a step plate 25 connected to the side wall surface 24. The side wall surface 24 and the step plate 25 enclose a second air guiding groove 232. Here, the second air guiding groove 232 can be formed by using the side wall surface 24 and the step plate 25, and the structure is simple and easy to implement. Among them, the cold air at the second air inlet 22 can flow along the side wall surface 24 and the step plate 25 towards the first air guiding groove 231. Here, by adding the step plate 25, when the second air guiding groove 232 penetrates through the air duct plate 2, it can be avoided that the cold air at the second air inlet 22 directly flows out of the second air guiding groove 232 after entering the second air guiding groove 232 instead of flowing towards the first air inlet 21 or the first air guiding groove 231. That is to say, by arranging the step plate 25, the cold air at the second air inlet 22 can normally flow through the second air guiding groove 232 towards the first air inlet 21 or the first air guiding groove 231, so as to ensure that the cold air in the above two parts can normally undergo convection.

[0037] In some embodiments of the present disclosure, referring to Figures 2 to 4 As shown, the refrigerator may further include a sealing film 6 disposed on the air duct plate 2. The sealing film 6 and the step plate 25 can enclose to form the second air inlet 22. It can be understood that the above sealing film 6 can cover the back side of the air duct plate 2 and is spaced apart from the step plate 25. In this way, the interval between the sealing film 6 and the step plate 25 can form the above second air inlet 22, so that the cold air entering the second air guiding groove 232 through the second air inlet 22 can smoothly flow along the step plate 25 towards the first air guiding groove 231.

[0038] In some embodiments of the present disclosure, referring to Figure 3 As shown, the second air guiding groove 232 may have a depth in the thickness direction of the air duct plate 2. The ratio of the depth of the second air guiding groove 232 to the thickness of the air duct plate 2 may be 0.3 - 0.5. In this way, when the ratio of the two is too small, it can be avoided that the amount of cold air participating in convection through the air guiding channel 23 is too small. In some embodiments, the thickness of the air duct plate 2 may be 26 mm - 28 mm, for example 27 mm. At this time, the depth of the second air guiding groove 232 may be 9 mm - 13 mm, and the thickness of the step plate 25 may be 14 mm - 18 mm.

[0039] In some embodiments of the present disclosure, referring to Figure 3 As shown, the second air guiding groove 232 may have a height in the length direction of the air duct plate 2. The height of the second air guiding groove 232 is 90 mm - 110 mm. Here, the height of the second air guiding groove 232 may be 100 mm, and the present disclosure does not limit this. In this way, the above setting can avoid the height of the second air guiding groove 232 being too high or too low.

[0040] In some embodiments of the present disclosure, referring to Figure 3 and Figure 4As shown, the air duct plate 2 can be provided with an air supply channel 26 and a plurality of air outlets 27 communicating with the air supply channel 26. The plurality of air outlets 27 are all in communication with the inner cavity 11. In this way, the cold air in the air supply channel 26 can be sent into the inner cavity 11 through the plurality of air outlets 27, realizing the refrigeration or freezing of the items in the inner cavity 11. Among them, in some embodiments, at least one air outlet 27 can be arranged above the air guiding channel 23, and the second air inlet 22 can be arranged between the first air inlet 21 and the air outlet 27. In this way, it can be understood that among the cold air sent into the inner cavity 11 through the air outlet 27, a part of the cold air sinks and then enters the air guiding channel 23 through the second air inlet 22 and flows downward along the air guiding channel 23 to flow to the first air inlet 21, and another part of the cold air continues to sink and then reaches the first air inlet 21. After that, these two parts of cold air can convect at the first air inlet 21.

[0041] In some embodiments of the present disclosure, with reference to Figures 1 to 4 As shown, a plurality of shelves 4 spaced apart in the up-and-down direction can be arranged in the box liner 1. The inner cavity 11 can include a storage space 111 arranged between two adjacent shelves 4. Among them, the first air inlet 21 and the air outlet 27 can communicate with different storage spaces 111 respectively, and at least a part of the second air inlet 22 can communicate with the storage space 111 communicating with the air outlet 27. In this way, for the air outlet 27 communicating with the same storage space 111 as the second air inlet 22, among the cold air sent into the storage space 111 through this air outlet 27, a part diffuses in the storage space 111, a part flows downward to reach the second air inlet 22 and enters the air guiding channel 23; for the first air inlet 21, since the first air inlet 21 and the air outlet 27 can communicate with different storage spaces 111 respectively, therefore, most of the cold air reaching the first air inlet 21 is the cold air diffused from other storage spaces 111. Such a setting method can ensure and even improve the accuracy of the temperature sensor 3 in collecting the cold air temperature in the inner cavity 11.

[0042] In some embodiments, with reference to Figure 3 As shown, the number of the air outlets 27 can be multiple, and the multiple air outlets 27 can be spaced apart in the up-and-down direction. Among them, at least two storage spaces 111 can communicate with at least one air outlet 27 respectively, and the present disclosure does not limit this.

[0043] In some embodiments, a protrusion can be formed in the box liner 1, and the above-mentioned shelf 4 can be arranged on the protrusion, and the present disclosure does not limit this.

[0044] In some embodiments of the present disclosure, with reference to Figure 1 、 Figure 2 and Figure 4As shown in the figure, the refrigerator may include an air duct cover plate 5 connected to the inner liner 1. One of the air duct cover plate 5 and the air duct plate 2 is provided with a buckle 28, and the other is provided with a clamping groove 51. The buckle 28 is clamped with the clamping groove 51. In this way, the clamping connection between the air duct cover plate 5 and the air duct plate 2 can be realized, so as to facilitate the disassembly and assembly of the air duct cover plate 5 and the air duct plate 2. Of course, in other embodiments, the air duct cover plate 5 and the air duct plate 2 can also be connected by fasteners, or the air duct cover plate 5 and the air duct plate 2 can also be bonded together. The present disclosure does not limit this too much.

[0045] In some embodiments of the present disclosure, referring to Figure 1 As shown in the figure, the refrigerator may include a sealing film 6. The sealing film 6 is disposed on the side of the air duct plate 2 facing away from the air duct cover plate 5 and is used to enclose the above-mentioned air supply channel 26 with the air duct plate 2. Among them, the sealing film 6 can be bonded to the air duct plate 2. The present disclosure does not limit this.

[0046] Next, the present disclosure will introduce in detail the specific flow direction of the cold air in the refrigerator in combination with the above specific embodiments. Referring to Figures 1 to 4 As shown in the figure, first, the cold air in the air supply channel 26 is sent into the inner cavity 11 through the air outlet 27. These cold airs will naturally sink. Part of the cold air sinks to reach the second air inlet 22 and enters the second air guide groove 232. Subsequently, the cold air continues to flow downward on the back side of the air duct plate 2 along the step plate 25, and then the cold air enters the first air guide groove 231; another part of the cold air continues to sink to reach the first air inlet 21. After that, the cold air enters the first air guide groove 231. Then, the above two parts of cold air can undergo forced convection in the first air guide groove 231 and at the first air inlet 21. Thus, the temperature sensing sensitivity of the temperature sensor 3 can be improved.

[0047] The preferred embodiments of the present disclosure have been described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.

[0048] In addition, it should be noted that, in the above specific embodiments, the various specific technical features described can be combined in any suitable manner without conflict. To avoid unnecessary repetition, the present disclosure will not separately describe various possible combination methods.

[0049] In addition, any combination can be made between various different embodiments of the present disclosure as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
