Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more particularly to a refrigerator. Background Technology

[0002] As people's living standards continue to improve, refrigerators have become an indispensable household appliance. A refrigerator has a storage compartment, which is typically used for the low-temperature refrigeration or freezing of items such as food and medicine.

[0003] Some users have a need for larger refrigerators. For example, while typical refrigerators have a capacity of around 150-350 liters, larger refrigerators can reach 400-450 liters or more. In frost-free refrigerators, the cooling method typically involves blowing air from the inside out along the depth of the refrigerator. Because larger-capacity refrigerators can store more items, the requirements for their cooling and temperature control are higher. When using frost-free cooling in these large-capacity refrigerators, the larger space means that the cold airflow may not cover the storage compartment sufficiently, potentially causing uneven cooling in some areas and affecting the refrigerator's refrigeration and freezing performance. Utility Model Content

[0004] This application discloses a refrigerator for improving the problem of uneven temperature in the storage compartment of a large-sized refrigerator.

[0005] To achieve the above objectives, this application discloses a refrigerator, comprising:

[0006] Box;

[0007] A freezer inner liner, wherein the freezer inner liner is disposed within the cabinet;

[0008] The refrigerator inner liner is located inside the cabinet and has an air outlet.

[0009] An air supply module is disposed in the inner liner of the freezer compartment and connected to the air outlet. The air supply module is configured to deliver cold air from the inner liner of the freezer compartment to the inner liner of the refrigerator compartment.

[0010] An air guide structure is provided on the inner surface of the refrigerator inner liner along the depth direction of the cabinet, and the air guide structure is connected to the air outlet;

[0011] A door, configured to close or open the freezer inner liner and the refrigerator inner liner;

[0012] The air guiding structure includes:

[0013] An air guide is provided on the inner surface of the refrigerator inner liner along the depth direction of the cabinet. An air duct cavity is formed on the side of the air guide facing the inner surface. The air duct cavity extends along the height direction of the cabinet and is connected to the air outlet.

[0014] A cover plate is attached to the side of the air guide away from the air duct cavity along the depth direction of the housing to cover the air guide.

[0015] The air duct cavity has the following characteristics:

[0016] A front air outlet, a side air outlet, and a top air outlet are sequentially arranged along the height direction of the cabinet. The cover plate is provided with a first air outlet, a second air outlet, and a third air outlet respectively corresponding to the front air outlet, the side air outlet, and the top air outlet. The front air outlet is configured to discharge air towards the depth direction of the cabinet. The side air outlet is configured to discharge air towards the side surface of the inner liner of the refrigerator along the width direction of the cabinet. The top air outlet is configured to discharge air towards the top surface of the inner liner of the refrigerator.

[0017] This application discloses a refrigerator with an air guide structure installed in the refrigerator compartment. The air guide structure directs cold air from the freezer compartment to the refrigerator compartment via air guide components. The cold air enters the air guide components from the air outlet of the refrigerator compartment and passes through a front air outlet, a side air outlet, and a top air outlet sequentially arranged on the air duct cavity. The cold air is then exited from the front air outlet, the side air outlet, and the top air outlet, and finally exited from a first air outlet, a second air outlet, and a third air outlet correspondingly arranged on the cover plate. Specifically, the front air outlet is configured to direct airflow towards the depth of the refrigerator compartment, the side air outlets are configured to direct airflow towards the side surface of the refrigerator compartment's interior in the width direction, and the top air outlet is configured to direct airflow towards the top surface of the refrigerator compartment's interior in the height direction. In this way, the space in the depth, height, and width directions of the refrigerator compartment is covered by the air outlets, enabling uniform cooling of the refrigerator compartment and preventing uneven temperature distribution within the refrigerator compartment.

[0018] As some alternative implementations, the air duct cavity includes:

[0019] A converging air duct, one end of which is connected to the air outlet along the height direction of the housing;

[0020] The diversion channel is connected to the other end of the converging air duct along the height direction of the housing. The diversion channel is spaced apart along the width direction of the housing. The front air outlet, the side air outlet and the top air outlet are sequentially arranged along the height direction of the housing.

[0021] Along the height direction of the cabinet, the diversion channel includes a first section and a second section that are interconnected. The second section is constructed as an inclined section that is tilted relative to the height direction of the cabinet, so that the second section is inclined toward the side surface of the inner liner of the refrigerator. The first section is provided with the front air outlet, and the second section is provided with the top air outlet and the side air outlet.

[0022] In the refrigerator compartment, considering the presence of electronic components such as ice makers on both sides of the width of the compartment, these components may generate heat during operation, potentially causing the side surfaces of the refrigerator compartment to become hot. When cold air enters the distribution channel, it first passes through the first section and exits through the front air outlet. Then, some of the cold air is blown to the second section, exiting through the side and top air outlets. Because the second section is inclined relative to the first section and faces the side surface of the refrigerator compartment, when air exits through the front air outlet of the second section, the inclination of the second section towards the side surface of the refrigerator compartment allows the top air outlet, which would normally face the top surface of the refrigerator compartment, to partially face the side surface of the refrigerator compartment. This assists the side air outlets in cooling the side surface of the refrigerator compartment, preventing it from becoming too hot due to the electronic components.

[0023] As some alternative implementations, the tilt angle of the second segment relative to the height direction of the box is α, where α is 5°-15°.

[0024] When the second section is tilted, it should be tilted relative to the height of the cabinet, with the tilt angle controlled between 5° and 15°. On one hand, if the tilt angle α < 5°, the second section will be relatively far from the side surface of the refrigerator's inner liner, potentially resulting in poor cooling effect from the side and top air outlets. On the other hand, if the tilt angle α > 15°, the second section will tilt excessively towards the width of the cabinet, occupying more space in the air guide component. This could increase the size of the air guide component in the width direction, making it difficult to install the air guide structure.

[0025] In response, this application discloses a method for controlling the tilt angle of the second section relative to the height of the cabinet, which allows the front and side air outlets to blow air better toward the inner liner of the refrigerator while preventing the air guide from being too large and saving space in the inner liner of the refrigerator.

[0026] As one alternative implementation, the top air outlet is located at the end of the end of the second segment along the extending direction of the second segment.

[0027] Because the second section extends at an angle towards the side surface of the refrigerator inner liner, its end can be closer to the side surface of the refrigerator inner liner. By placing the front air outlet at the end of the second section, the top air outlet can be closer to the side surface of the refrigerator inner liner, so that the cold air blown from the top air outlet toward the top surface of the refrigerator inner liner can be partially blown toward the side surface of the refrigerator inner liner, thereby assisting the side air outlet in cooling the side surface of the refrigerator inner liner.

[0028] As some alternative implementations, along the extension direction of the second segment, the side air outlet is disposed adjacent to the top air outlet, and the side air outlet is disposed on the side surface of the second segment adjacent to the inner liner of the refrigerator compartment.

[0029] This application positions the side air outlet near the top air outlet, placing it at the end of the second section and also near the side surface of the refrigerator inner liner. This allows the side air outlet to not only exhaust air onto the side surface of the refrigerator inner liner but also onto the top of that surface, ensuring that cold air flows from the top to the bottom of the inner liner's side surface, effectively cooling the entire surface.

[0030] As some alternative implementations, the air guide includes:

[0031] Two first air guide surfaces are arranged facing each other along the width direction of the housing;

[0032] Two second air guide surfaces are arranged facing each other along the width direction of the housing, and the two second air guide surfaces are located between the two first air guide surfaces in the width direction of the housing;

[0033] The first air guide surface includes:

[0034] The first dominant airflow surface and the two first dominant airflow surfaces are arranged opposite each other along the width direction of the box to define the converging airflow duct;

[0035] The first sub-air guide surface is connected to the first main air guide surface along the height direction of the housing, and the first sub-air guide surface is arranged opposite to the second air guide surface along the width direction of the housing to define the diversion channel.

[0036] The first sub-guide surface includes:

[0037] The first sub-face, one side of which is connected to the first prevailing wind face;

[0038] The second sub-surface is provided with the side air outlet. The second sub-surface is inclined toward the side surface of the inner liner of the refrigerator, so that the side air outlet is set to narrow toward the side surface of the inner liner of the refrigerator.

[0039] Understandably, the airflow channel is constructed from a first sub-air guide surface and a second air guide surface. The first sub-air guide surface is close to the side surface of the refrigerator inner liner; therefore, the side air outlet is located on the first sub-air guide surface. The first sub-air guide surface further includes a first sub-surface and a second sub-surface. The second sub-surface is inclined towards the side surface of the refrigerator inner liner, allowing it to be close to the side surface of the refrigerator inner liner. Along the width of the cabinet, the side air outlet gradually narrows. When cold air exits from the side air outlet, it is accelerated after passing through the narrower side air outlet, allowing the cold air to be better directed towards the side surface of the refrigerator inner liner, effectively cooling the side surface of the refrigerator inner liner.

[0040] As some alternative implementations, along the depth direction of the housing, the air guide further includes:

[0041] The third air guide surface includes:

[0042] The second dominant airflow surface connects the two first dominant airflow surfaces along the width direction of the housing.

[0043] The second sub-air guide surface is connected to the second main air guide surface along the height direction of the housing. The second sub-air guide surface is connected to the first sub-air guide surface and the second air guide surface along the width direction of the housing. The top air outlet is provided on the side of the second sub-air guide surface away from the second main air guide surface. The second sub-air guide surface is inclined towards the depth direction of the housing so that the top air outlet faces the depth direction of the housing.

[0044] The second sub-air guide surface is set along the depth direction of the cabinet, and when the top air outlet is located on the second sub-air guide surface, the opening of the top air outlet faces the depth direction of the cabinet. Since the second sub-air guide surface extends along the height direction of the cabinet while also tilting towards the depth direction, cold air can be guided from the top air outlet along the height direction of the cabinet, and then tilted out towards the top surface of the refrigerator inner liner along the depth direction of the cabinet. This allows cold air to exit towards the top surface of the refrigerator inner liner while also allowing some cold air to blow out along the depth direction of the cabinet, enabling the top air outlet to better cover the space inside the refrigerator inner liner for more even cooling.

[0045] As some optional implementations, the air guiding structure further includes:

[0046] Lighting element, wherein the lighting element is disposed on at least one side of the cover plate along the width direction of the housing;

[0047] The cover plate includes:

[0048] The panel is connected to the air guide along the depth direction of the housing. The panel is provided with a first air vent, a second air vent and a third air vent. The first air vent and the third air vent are located on the front of the panel along the depth direction of the housing, and the second air vent is located on the side of the panel along the width direction of the housing.

[0049] The mounting part is located on the side of the panel and is spaced apart from the front of the panel along the depth direction of the housing. The mounting part is provided with a light groove, and the lighting element is located in the light groove. The bottom surface of the light groove along the depth direction of the housing is provided with a light-emitting hole, and the light-emitting hole is configured to allow the lighting element to emit light towards the front of the panel.

[0050] Considering the large size and depth of the refrigerator's inner liner, the inner surface of the inner liner has poor brightness along its depth direction. The interior lighting of the inner liner is insufficient to illuminate this surface, making it difficult for users to see items inside. To address this, this application incorporates a lighting element within the airflow structure. Because the airflow structure is located on the inner surface of the inner liner, this lighting element illuminates the inner surface, providing supplemental lighting and allowing users to see items located deeper within the refrigerator, thus facilitating their retrieval.

[0051] In addition, by mounting the lighting components on the side of the panel, the light emitted by the lighting components can be blocked by the front of the panel and emitted from the side. This not only provides illumination but also prevents the lighting components from emitting light directly along the depth of the enclosure, which could potentially cause direct irradiation to the user's eyes.

[0052] As some alternative implementations, the cover plate also includes:

[0053] A light guide plate is disposed between the mounting portion and the panel portion along the depth direction of the housing, and the light guide plate extends along the width direction of the housing. The light guide plate is configured to guide the light from the lighting element along the width direction of the housing.

[0054] In the width direction of the housing, the light guide plate is spaced apart from the mounting part to form a side air outlet duct that communicates with the second air vent.

[0055] On the one hand, when the lighting element emits light towards the depth of the enclosure, it illuminates the light guide plate, which extends along the width of the enclosure. When the light from the lighting element hits the light guide plate, the light can be directed along the width of the enclosure, preventing it from directly hitting the panel and affecting its appearance. Furthermore, the light is directed along the width of the enclosure, avoiding direct light emission along its depth, resulting in a softer lighting effect that is more eye-friendly.

[0056] On the other hand, since the second air vent is also located on the side of the panel, the side air outlet can pass through the second air vent and then exit between the lighting element and the light guide plate. The side air outlet duct formed by the spacing between the lighting element and the light guide plate can supply air to the second air vent. Since the light guide plate extends along the width of the cabinet, it can effectively guide the cold air blown out by the second air vent to the side surface of the inner liner of the refrigerator. In other words, by setting a light guide plate on the cover plate, it can guide the light from the lighting element on the one hand, and also utilize the side air outlet duct formed between the light guide plate and the cover plate on the other hand. The overall structure is more compact, and the reuse of the light guide plate makes the overall structure of the light guiding structure more compact.

[0057] As some alternative implementations, the light guide plate is arranged parallel to the width direction of the housing; or,

[0058] The light guide plate is inclined relative to the width direction of the housing, and the inclination angle of the light guide plate is β, where β is 30°-60°.

[0059] When setting the light guide plate in this application, the light guide plate can be tilted, for example, the tilt angle β of the light guide plate can be 30°-60°. On the one hand, when β < 30°, the tilt angle of the light guide plate is small, and some of the light that hits the light guide plate is easily reflected back to the lighting element, affecting the lighting effect of the lighting element. On the other hand, when β > 60°, the light guide plate will be more biased towards the depth direction of the cabinet, and some light will easily be emitted along the light guide plate into the depth direction of the cabinet, resulting in more light hitting the user side, affecting the user's use.

[0060] In response, this application sets the tilt angle of the light guide plate at 30°-60°, which reduces the amount of light emitted along the depth direction of the cabinet while also preventing light from being reflected back to the lighting components, so that the light can be effectively emitted along the width direction of the cabinet, achieving a softer lighting effect.

[0061] Compared with the prior art, this application has at least the following beneficial effects:

[0062] The refrigerator disclosed in this application has an air guiding structure installed in the refrigerator inner liner. This structure guides cold air from the freezer inner liner to the refrigerator inner liner via air guide components. After entering the air guide components from the air outlet of the refrigerator inner liner, the cold air is guided through the converging air duct of the air duct cavity to two branching channels. These two branching channels can deliver the cold air to both sides of the refrigerator inner liner in the width direction of the refrigerator body. A front air outlet, a side air outlet, and a top air outlet are sequentially provided in the branching channels. The cold air is discharged from the front air outlet, the side air outlet, and the top air outlet, and then discharged from the corresponding first air outlet, second air outlet, and third air outlet on the cover plate. Specifically, the front air outlet is configured to discharge air towards the depth direction of the refrigerator body, the side air outlet is configured to discharge air towards the side surface of the refrigerator inner liner in the width direction of the refrigerator body, and the top air outlet is configured to discharge air towards the top surface of the refrigerator inner liner in the height direction of the refrigerator body. In this way, the space in the depth, height, and width of the refrigerator's inner liner can all be covered by the air outlet, enabling uniform cooling of the refrigerator's inner liner and preventing uneven temperature distribution within the refrigerator's inner liner.

Detailed Implementation

[0079] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0080] In this application, the terms "upper," "lower," "top," "bottom," "inner," "outer," and "middle," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0081] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0082] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0083] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or parts (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, components, or parts. Unless otherwise stated, "a plurality of" means two or more.

[0084] As people's living standards continue to improve, refrigerators have become an indispensable household appliance. A refrigerator has a storage compartment, which is typically used for the low-temperature refrigeration or freezing of items such as food and medicine.

[0085] Some users have a need for large-sized refrigerators. For example, refrigerators typically have a capacity of around 150-350 liters, while larger refrigerators can reach 400-450 liters or more. In frost-free refrigerators, the airflow system is located inside the storage compartment along the depth of the refrigerator. The cooling method usually involves blowing cold air from the inside out along the depth of the refrigerator through this system. Because larger-capacity refrigerators can store more items, the requirements for cooling and temperature control are also higher. When using frost-free cooling in these large-capacity refrigerators, the larger space means that the cold airflow may not cover the entire storage compartment, potentially causing uneven cooling in some areas and affecting the refrigerator's refrigeration and freezing performance.

[0086] In addition, because the refrigerator's storage compartment is quite deep, the lighting inside is poor, making it difficult for users to observe the contents and retrieve items.

[0087] Based on this, this application discloses a refrigerator that, in order to improve the uneven temperature inside the refrigerator compartment, provides a front air outlet, a side air outlet, and a top air outlet on the air guide component of the air guide structure, allowing air to exit from the first, second, and third air outlets on the cover plate, respectively. Specifically, the front air outlet is configured to direct airflow towards the depth of the refrigerator compartment, the side air outlet is configured to direct airflow towards the side surface of the refrigerator compartment's inner liner in the width direction, and the top air outlet is configured to direct airflow towards the top surface of the refrigerator compartment's inner liner in the height direction. In this way, the space in the depth, height, and width directions of the refrigerator compartment's inner liner is covered by the air outlets, enabling uniform cooling of the refrigerator compartment and preventing uneven temperature distribution within the refrigerator compartment.

[0088] Furthermore, this application also includes a lighting element on the air guide structure. The air guide structure is located on the inner surface of the refrigerator's inner liner in the depth direction of the cabinet, so that the lighting element can illuminate the interior of the refrigerator, improving the situation where the lighting effect is poor due to the depth of the refrigerator interior.

[0089] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0090] Please see Figure 1 This application discloses a refrigerator 100, which can be, for example, a double-door refrigerator 100, a single-door refrigerator 100, a three-door refrigerator 100, or a French door refrigerator 100. Alternatively, it can be a French door refrigerator 100, that is, the upper part is a double-door refrigerator compartment, providing users with spacious storage space, and the lower part is usually a drawer-type freezer compartment, which makes it easier to classify, store, and access frozen foods. The specific form is not limited in this application embodiment.

[0091] Please see Figure 1 In some embodiments, the refrigerator 100 includes a cabinet 1, which has a refrigerator inner liner 11 and a freezer inner liner 12.

[0092] Understandably, the temperature of the inner liner 11 of the refrigerator compartment is usually between 0℃ and 8℃, which keeps food in a refrigerated state. The temperature of the inner liner 12 of the freezer compartment is usually between -14℃ and -26℃, which keeps food in a frozen state.

[0093] It is understandable that the inner liner of the refrigerator compartment 11 can be located above the inner liner of the freezer compartment 12, or the inner liner of the freezer compartment 12 can be located above the inner liner of the refrigerator compartment 11, or the inner liner of the freezer compartment 12 and the inner liner of the refrigerator compartment 1 can be arranged along the width direction of the cabinet 1.

[0094] exist Figure 1 In the example, X indicates the width of box 1, Y indicates the depth of box 1, and Z indicates the height of box 1.

[0095] In some embodiments, the refrigerator 100100 includes a door (not shown) that is movably connected to the cabinet 1 to open or close the refrigerator inner liner 11 and the freezer inner liner 12 to prevent cold air leakage from the refrigerator inner liner 11 and the freezer inner liner 12.

[0096] In some embodiments, the refrigerator 100 further includes a refrigeration module (not shown), which is disposed inside the cabinet 1. The refrigeration module can lower the inner liner of the refrigerator compartment 11 and the inner liner of the freezer compartment 12 to different temperatures to meet the different storage needs of users.

[0097] Optionally, the refrigeration module can be an air-cooled refrigeration module, which is installed in the freezer inner liner 12. The air-cooled refrigeration module may include a compressor, condenser, evaporator, capillary tube, and fan. After the compressor, condenser, evaporator, and capillary tube generate cold air through the cooling process, the fan blows air onto the evaporator. The air after passing through the evaporator becomes cold air, which can be blown onto the refrigerator inner liner 11 and the freezer inner liner 12 for cooling.

[0098] Please see Figure 2 and Figure 3 Optionally, the inner liner of the refrigerator compartment 11 is provided with an air outlet 111, through which cold air from the inner liner of the freezer compartment 12 can be delivered to the inner liner of the refrigerator compartment 11.

[0099] In some embodiments, the refrigerator 100 further includes an air supply module (not shown), which is disposed in the freezer inner liner 12 and connected to the air outlet 111. The air supply module is configured to deliver cold air from the freezer inner liner 12 to the refrigerator inner liner 11.

[0100] Understandably, the air supply module is a fan, which blows cold air from the freezer inner liner 12 into the refrigerator inner liner 11.

[0101] In some embodiments, the refrigerator 100 further includes an air guide structure 2, which is disposed on the inner surface 11a of the inner liner 11 of the refrigerator compartment along the depth direction of the compartment 1, and the air guide structure 2 is connected to the air outlet 111.

[0102] For example, when cold air is delivered from the air outlet 111 to the inner liner of the refrigerator through the air supply module, the cold air can be blown into the inner liner of the refrigerator through the air guide structure 2.

[0103] Please see Figure 4 and Figure 5 In some embodiments, the air guide structure 2 includes an air guide 21 and a cover plate 22.

[0104] Optionally, the air guide 21 is disposed on the inner surface 11a of the inner liner 11 of the refrigerator along the depth direction of the cabinet 1, and an air duct cavity 21a is formed on the side of the air guide 21 facing the inner surface 11a, and the air duct cavity 21a extends along the height direction of the cabinet 1.

[0105] Understandably, after the cold air enters the air guide 21, it is sent to the inner liner 11 of the refrigerator through the air duct cavity 21a.

[0106] Optionally, the cover plate 22 is connected to the side of the air guide 21 away from the air duct cavity 21a along the depth direction of the housing 1 to cover the air guide 21.

[0107] To maintain the insulation effect of cold air, the air guide 21 is usually made of insulating foam. However, directly placing the insulating foam in the inner liner 11 of the refrigerator is not only prone to damage but also aesthetically unappealing. To address this, a cover plate 22 is provided on the air guide 21 to cover it, thereby protecting the air guide 21 and improving its appearance.

[0108] Please see Figures 2 to 5 In some embodiments, the air duct cavity 21a includes a converging air duct 21aa and two branching channels 21ab. One end of the converging air duct 21aa along the height direction of the housing 1 is connected to the air outlet 111. The two branching channels 21ab are respectively connected to the other end of the converging air duct 21aa along the height direction of the housing 1. The two branching channels 21ab are spaced apart along the width direction of the housing 1. The branching channels 21ab are sequentially provided with a front air outlet 21b, a side air outlet 21c, and a top air outlet 21d along the height direction of the housing 1. The cover plate 22 is provided with a first air outlet 22a, a second air outlet 22b, and a third air outlet 22c corresponding to the front air outlet 21b, the side air outlet 21c, and the top air outlet 21d, respectively. The front air outlet 21b is configured to discharge air towards the depth direction of the cabinet 1, the side air outlet 21c is configured to discharge air towards the side surface 11b of the inner liner of the refrigerator along the width direction of the cabinet 1, and the top air outlet 21d is configured to discharge air towards the top surface 11c of the inner liner of the refrigerator.

[0109] This application discloses a refrigerator 100, in which an air guide structure 2 is installed in the refrigerator inner liner 11. The air guide structure 2 guides cold air from the freezer inner liner 12 to the refrigerator inner liner 11 via an air guide component 21. After the cold air enters the air guide component 21 from the air outlet 111 of the refrigerator inner liner 11, it is guided through the converging air duct 21aa of the air duct cavity 21a to two diversion channels 21ab. The two diversion channels 21ab can deliver the cold air to both sides of the refrigerator inner liner 11 in the width direction of the cabinet 1, so that the cold air can be evenly distributed on both sides of the refrigerator inner liner 11. The diversion channels 21ab are provided with a front air outlet 21b, a side air outlet 21c, and a top air outlet 21d in sequence. To ensure that cold air passes through the air guide 21 and exits through the cover plate 22, the cold air is exited from the front air outlet 21b, the side air outlet 21c, and the top air outlet 21d, and then exits from the corresponding first air outlet 22a, second air outlet 22b, and third air outlet 22c on the cover plate 22. Specifically, the front air outlet 21b is configured to exit air towards the depth direction of the cabinet 1, the side air outlet 21c is configured to exit air towards the side surface 11b of the refrigerator inner liner 11 in the width direction of the cabinet 1, and the top air outlet 21d is configured to exit air towards the top surface 11c of the refrigerator inner liner 11 in the height direction of the cabinet 1. In this way, the space in the depth direction, the height direction, and the width direction of the refrigerator inner liner 11 can all be covered by the air outlets, achieving uniform cooling of the refrigerator inner liner 11 and preventing uneven temperature distribution within the refrigerator inner liner 11.

[0110] Understandably, the air guide component 21 can be a piece of foam board molded from insulating foam using a mold, and the air duct cavity 21a is integrally molded onto the air guide component 21, with each surface of the air guide component 21 forming the air duct cavity 21a. By integrally molding the air guide component 21 and the air duct cavity 21a with insulating foam, the subsequent additional processing on the air guide component is avoided, which would damage the insulation effect of the air guide component.

[0111] It is understandable that the diversion channels 21ab can also be three, four, etc., and this application does not make specific limitations here.

[0112] Combination Figure 6 As shown, in some embodiments, the air guide 21 includes two first air guide surfaces 211 arranged opposite each other along the width direction of the housing 1, two second air guide surfaces 212 arranged opposite each other along the width direction of the housing 1, and a third air guide surface 213 arranged along the depth direction of the housing 1. The two first air guide surfaces 211, the third air guide surface 213, and the two second air guide surfaces 212 are configured as an air duct cavity 21a.

[0113] like Figure 6Optionally, the first air guide surface 211 includes a first main air guide surface 211a and a first sub-air guide surface 211b connected along the height direction of the housing 1. The third air guide surface 213 includes a second main air guide surface 213a and a second sub-air guide surface 213b connected along the height direction of the housing 1. The second main air guide surface 213a connects the two first main air guide surfaces 211a to define a converging airflow channel 21aa, and the second sub-air guide surface 213b connects the first sub-air guide surface 211b and the second air guide surface 212 to define a diversion channel 21ab.

[0114] In the refrigerator 100 of this application, the converging air duct 21aa is defined by a first main airflow surface 211a and a second main airflow surface 213a, and the diversion channel 21ab is defined by a first sub-airflow surface 211b, a second sub-airflow surface 213b, and a second airflow surface 212. The air ducts defined by each airflow surface can guide cold air along the height direction of the cabinet 1 to each air outlet, so that the cold air can be discharged from the corresponding air outlet, avoiding interference between air ducts and improving the smoothness of cold air delivery.

[0115] Please combine Figures 7 to 9 Optionally, the first sub-air guide surface 211b includes a first sub-surface 2111 and a second sub-surface 2112. One side of the first sub-surface 2111 is connected to the first main air guide surface 211a. The second sub-surface 2112 is provided with a side air outlet 21c. The second sub-surface 2112 is inclined toward the side surface 11b of the inner liner of the refrigerator compartment 11, so that the side air outlet 21c is narrowed toward the side surface 11b of the inner liner of the refrigerator compartment 11.

[0116] It is understandable that the diversion channel 21ab is defined by the first sub-guide surface 211b, the second sub-guide surface 213b, and the second guide surface 212.

[0117] For example, the first sub-air guide surface 211b is close to the side surface 11b of the refrigerator inner liner 11, therefore, the side air outlet 21c is disposed on the first sub-air guide surface 211b. The first sub-air guide surface 211b further includes a first sub-surface 2111 and a second sub-surface 2112. The second sub-surface 2112 is inclined toward the side surface 11b of the refrigerator inner liner 11, so that the second sub-surface 2112 can be close to the side surface 11b of the refrigerator inner liner 11. The second sub-surface 2112 extends toward the side surface 11b of the refrigerator inner liner 11 along the width direction of the cabinet 1, so that the side air outlet 21c can be close to the side surface 11b of the refrigerator inner liner 11. As the side air outlet 21c gradually narrows along the width of the cabinet 1, according to Bernoulli's principle, when cold air is emitted from the side air outlet 21c, it can be accelerated after passing through the narrower side air outlet 21c, so that the cold air can be better blown to the side surface 11b of the inner liner of the refrigerator 11, and the side surface 11b of the inner liner of the refrigerator 11 can be effectively cooled.

[0118] Please see Figure 10 Optionally, along the height direction of the housing 1, the second sub-guide surface 213b is provided with a top air outlet 21d on the side away from the second main guide surface 213a, and the second sub-guide surface 213b is inclined toward the depth direction of the housing 1 so that the top air outlet 21d is toward the depth direction of the housing 1.

[0119] For example, the second sub-air guide surface 213b is arranged along the depth direction of the cabinet 1, and when the top air outlet 21d is arranged on the second sub-air guide surface 213b, the opening of the top air outlet 21d faces the depth direction of the cabinet 1. Since the fourth side d of the second sub-air guide surface 213b extends towards the height direction of the cabinet 1 while tilting towards the depth direction of the cabinet 1, cold air can be guided along the height direction of the cabinet 1, and then tilted out towards the top surface 11c of the refrigerator inner liner 11 along the depth direction of the cabinet 1. This allows the cold air to be discharged towards the top surface 11c of the refrigerator inner liner 11, while also allowing some cold air to be blown out along the depth direction of the cabinet 1. This allows the top air outlet 21d to better cover the space of the refrigerator inner liner 11 for air discharge, so as to cool the refrigerator inner liner 11 more evenly.

[0120] Please see also Figures 6 to 10 In some embodiments, along the height direction of the housing 1, the diversion channel 21ab includes a first section 21ac and a second section 21ad that are interconnected. The second section 21ad is constructed as an inclined section that is inclined relative to the height direction of the housing 1, so that the second section 21ad is inclined toward the side surface 11b of the inner liner 11 of the refrigerator. The first section 21ac is provided with a front air outlet 21b, and the second section 21ad is provided with a top air outlet 21d and a side air outlet 21c.

[0121] It is understood that, along the height direction of the housing 1, the second sub-air guide surface 213b includes a first part a and a second part b. The first segment 21ac is defined by the first sub-surface 2111, the first part a and a portion of the second air guide surface 212, and the second segment 21ad is defined by the second sub-surface 2112, the second part b and a portion of the second air guide surface 212.

[0122] In the inner liner 11 of the refrigerator compartment, considering that electronic components such as ice makers (not shown) are also installed on both sides of the width direction of the compartment 1, these electronic components may generate heat during operation, which may cause the side surface 11b of the inner liner 11 of the refrigerator compartment to have a high temperature. When cold air flows into the distribution channel 21ab, the cold air first passes through the first section 21ac and exits from the front air outlet 21b. Then, part of the cold air is blown to the second section 21ad and exits from the side air outlet 21c and the top air outlet 21d of the second section 21ad. Since the second section 21ad is inclined relative to the first section 21ac and the second section 21ad is inclined toward the side surface 11b of the refrigerator compartment. When air is discharged from the front air outlet 21b of the second section 21ad, since the second section 21ad is inclined toward the side surface 11b of the refrigerator compartment, the top air outlet 21d, which originally discharged air toward the top surface 11c of the refrigerator inner liner 11, can partially discharge air toward the side surface 11b of the refrigerator inner liner 11. This assists the side air outlet 21c in discharging air, thereby cooling the side surface 11b of the refrigerator inner liner 11, alleviating the relatively high temperature caused by the electronic components on the side surface 11b of the refrigerator inner liner 11, and improving the temperature uniformity in the refrigerator inner liner 11.

[0123] Alternatively, electronic components may also be condensers, heat sinks, etc.

[0124] Please see Figure 6 In some embodiments, the tilt angle of the second segment 21ad relative to the height direction of the box 1 is α, where α is 5°-15°.

[0125] For example, α can be 5°-7°, 7°-9°, 9°-11°, 11°-13°, 13°-15°, etc. For instance, α can be 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, or 15°, etc.

[0126] When the second segment 21ad is tilted, it is tilted relative to the height of the cabinet 1, and the tilt angle of the second segment 21ad relative to the height of the cabinet 1 is controlled between 5° and 15°. On the one hand, if the tilt angle α of the second segment 21ad is less than 5°, the tilt angle of the second segment 21ad relative to the height of the cabinet 1 is small, and the second segment 21ad will be relatively far away from the side surface 11b of the inner liner of the refrigerator compartment 11. This may result in poor cooling effect of the side air outlet 21c and the top air outlet 21d on the side surface 11b of the inner liner of the refrigerator compartment 11. On the other hand, if the tilt angle α of the second segment 21ad is greater than 15°, the second segment 21ad is tilted too much towards the width of the cabinet 1. The second segment 21ad occupies more space in the width direction of the cabinet 1, which may increase the size of the air guide 21 in the width direction of the cabinet 1. This will cause the air guide 21 to occupy more space in the width direction of the cabinet 1, making it inconvenient to install the air guide structure 2.

[0127] In this regard, this application discloses the tilt angle of the second section 21ad relative to the height direction of the cabinet 1, so that the front air outlet 21b and the side air outlet 21c can blow air towards the inner liner of the refrigerator better, while also preventing the size of the air guide 21 from being too large and saving space in the inner liner of the refrigerator.

[0128] In some embodiments, along the extending direction of the second segment 21ad, the top air outlet 21d is located at the end of the end of the second segment 21ad.

[0129] Because the second segment 21ad extends obliquely toward the side surface 11b of the refrigerator inner liner 11, the end of the second segment 21ad can be closer to the side surface 11b of the refrigerator inner liner 11. By placing the front air outlet 21b at the end of the second segment 21ad, the top air outlet 21d can be closer to the side surface 11b of the refrigerator inner liner 11, so that the cold air blown by the top air outlet 21d toward the top surface 11c of the refrigerator inner liner 11 can be partially blown toward the side surface 11b of the refrigerator inner liner 11, thereby assisting the side air outlet 21c in cooling the side surface 11b of the refrigerator inner liner 11.

[0130] In some embodiments, along the extending direction of the second segment 21ad, the side air outlet 21c is disposed near the top air outlet 21d, and the side air outlet 21c is disposed on the side of the second segment 21ad near the side surface 11b of the inner liner of the refrigerator compartment 11.

[0131] In this application, the side air outlet 21c is positioned near the top air outlet 21d, so that the side air outlet 21c is also located at the end of the second section 21ad, and the side air outlet 21c is also positioned near the side surface 11b of the refrigerator inner liner 11 on the second section 21ad. In this way, the side air outlet 21c can not only exhaust air towards the side surface 11b of the refrigerator inner liner 11, but also towards the top of the side surface 11b of the refrigerator inner liner 11, so that cold air can be blown from the top to the bottom of the side surface 11b of the refrigerator inner liner 11, and the entire side surface 11b of the refrigerator inner liner 11 can be effectively cooled.

[0132] Please see Figure 2 Optionally, along the height direction of the housing 1, the distance between the side air outlet 21c and the top air outlet 21d can be d1, where d1 can be 10mm-50mm.

[0133] For example, d1 can be 10mm-20mm, 20mm-30mm, 30mm-40mm, 40mm-50mm, etc. For instance, d1 can be 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, or 50mm, etc.

[0134] In the refrigerator disclosed in this application, the distance between the side air outlet 21c and the top air outlet 21d is set to 10mm-50mm, so that the side air outlet 21c can be close to the top air outlet 21d to discharge air. When the side air outlet blows air onto the side surface 11b of the refrigerator inner liner 11, it can be close to the top of the side surface 11b of the refrigerator inner liner 11, so that the side surface 11b of the refrigerator inner liner 11 can be cooled from top to bottom, and the side surface 11b of the refrigerator inner liner 11 can be cooled evenly.

[0135] If the side air outlet 21c and the top air outlet 21d are close together (d1 < 10 mm), the side air outlet 21c may interfere with the airflow from the top air outlet 21d. If the side air outlet 21c and the top air outlet 21d are far apart (d1 > 50 mm), the distance between them is too great, which is not conducive to the side air outlet 21c blowing air towards the top of the side surface 11b of the inner liner of the refrigerator, thus affecting the temperature uniformity of the side surface 11b of the inner liner of the refrigerator.

[0136] Therefore, setting the distance between the side air outlet 21c and the top air outlet 21d to 10mm-50mm can not only improve the cooling uniformity of the side surface 11b of the inner liner 11 of the refrigerator, but also avoid the interference of the side air outlet 21c to the top air outlet 21d.

[0137] Please see Figure 2Optionally, along the width direction of the cabinet 1, the distance between the side air outlet 21c and the side surface 11b of the inner liner of the refrigerator can be d2, where d2 can be 50mm-300mm.

[0138] For example, d2 can be 50mm-70mm, 70mm-90mm, 90mm-110mm, 110mm-130mm, 130mm-150mm, 150mm-170mm, 170mm-190mm, 190mm-210mm, 210mm-230mm, 230mm-250mm, 250mm-270mm, 270mm-300mm, etc. For example... d2 can be 50mm, 60mm, 70mm, 80mm, 90mm, 100mm, 110mm, 120mm, 130mm, 140mm, 150mm, 160mm, 170mm, 180mm, 190mm, 200mm, 210mm, 220mm, 230mm, 240mm, 250mm, 260mm, 270mm, 280mm, 290mm, or 300mm, etc.

[0139] In the refrigerator disclosed in this application, the distance between the side air outlet 21c and the side surface 11b of the inner liner 11 of the refrigerator is set between 50mm and 300mm. On the one hand, this avoids the side air outlet 21c being too far from the side surface 11b of the inner liner 11, preventing cold air from blowing back onto the side surface 11b and affecting the airflow from the side air outlet 21c. On the other hand, it avoids the side air outlet 21c being too far from the side surface 11b of the inner liner 11, which would be detrimental to the delivery of cold air to the side surface 11b of the inner liner 11.

[0140] Considering the considerable depth of the refrigerator inner liner 11, the internal lighting effect of the refrigerator inner liner 11 is poor. Please refer to [link / reference needed]. Figures 11 to 13 In some embodiments, the air guide structure 2 further includes an illumination element 23, which is disposed on at least one side of the cover plate 22 along the width direction of the housing 1.

[0141] By setting an illumination element 23 on the air guide structure 2, the illumination element 23 illuminates the inner surface 11a of the refrigerator inner liner 11 to supplement the light in the refrigerator inner liner 11, so that the user can observe the situation in the refrigerator inner liner 11.

[0142] Please see Figure 12 and Figure 13Optionally, the cover plate 22 includes a panel portion 221 and a mounting portion 222. The panel portion 221 is connected to the air guide 21 along the depth direction of the housing 1. The panel portion 221 is provided with a first air vent 22a, a second air vent 22b, and a third air vent 22c. The first air vent 22a and the third air vent 22c are located on the front side 221b of the panel portion along the depth direction of the housing 1, and the second air vent 22b is located on the side side 221a of the panel portion along the width direction of the housing 1. The mounting portion 222 is located on the side side 221a of the panel portion, and the mounting portion 222 is spaced apart from the front side 221b of the panel portion along the depth direction of the housing 1. The mounting portion 222 is provided with a light groove 2221, and the lighting element 23 is located in the light groove 2221. The bottom surface of the light groove 2221 along the depth direction of the housing 1 is provided with a light emission hole 222a, which is configured to allow the lighting element 23 to emit light towards the front side 221b of the panel portion.

[0143] Considering the large size and depth of the refrigerator inner liner 11, the brightness of its inner surface 11a in the depth direction of the refrigerator body 1 is poor. The lighting in the refrigerator inner liner 11 is insufficient to illuminate its inner surface 11a, making it difficult for users to see items inside. To address this, this application also includes a lighting element 23 on the air guide structure 2. Because the air guide structure 2 is located on the inner surface 11a of the refrigerator inner liner 11, the lighting element 23 can illuminate the inner surface 11a of the refrigerator inner liner 11, providing supplemental lighting and allowing users to see items located deeper within the refrigerator inner liner 11 for easier retrieval.

[0144] Please see Figure 11 Furthermore, the lighting element 23 is mounted on the side 221a of the panel via the mounting part 222 and is shielded by the front 221b of the panel to prevent the lighting element 23 from emitting light directly along the depth direction of the housing 1, thus preventing direct irradiation to the user's eyes.

[0145] Optionally, the lighting element 23 may be a light strip, a light bead, etc., and this application does not make specific limitations here.

[0146] Optionally, the mounting portion 222 can be block-shaped or plate-shaped to facilitate the installation of the lighting element 23 by slotting it. Moreover, providing light-emitting holes 222a on the plate-shaped or block-shaped mounting portion 222 is less likely to damage the structure of the mounting portion 222, which helps maintain the strength of the structure.

[0147] Optionally, the panel portion 221 may be plate-shaped or block-shaped. In order to better cover the air guide 21, the shape of the panel portion 221 may be adapted to the shape of the air guide 21.

[0148] In some embodiments, the lighting element 23 is detachably connected to the mounting portion 222.

[0149] For example, the mounting part 222 is provided with a buckle. When the lighting element 23 is installed in the mounting part 222, the lighting element 23 is fixed in the lamp groove 2221 by the buckle, so as to realize the detachable connection between the lighting element 23 and the mounting part 222, so as to facilitate the disassembly or installation of the lighting element 23 and improve assembly efficiency.

[0150] Please see Figure 11 In some embodiments, the cover plate 22 further includes a light guide plate 223, which is disposed between the mounting portion 222 and the panel portion 221 along the depth direction of the housing 1. The light guide plate 223 extends along the width direction of the housing 1 and is configured to guide the light from the illuminator 23 along the width direction of the housing 1.

[0151] For example, when the illuminator 23 emits light in the depth direction of the housing 1, the illuminator 23 illuminates the light guide plate 223, which extends along the width direction of the housing 1. When the light from the illuminator 23 illuminates the light guide plate 223, the light can be directed in the width direction of the housing 1, preventing the light from directly illuminating the panel portion 221 and affecting its appearance. Moreover, the light can be directed along the width direction of the housing 1, preventing the light from directly emitting along the depth direction of the housing 1, making the illumination effect of the illuminator softer and more eye-friendly for the user.

[0152] Optionally, in the width direction of the housing 1, the light guide plate 223 is spaced apart from the mounting portion 222 to form a side air outlet duct communicating with the second air outlet 22b.

[0153] For example, since the second air vent 22b is also located on the side 221a of the panel, the side air outlet 21c can pass through the second air vent 22b and then exit from between the lighting element 23 and the light guide plate 223. The side air outlet duct formed by the lighting element 23 and the light guide plate 223 can supply air to the second air vent 22b. Since the light guide plate 223 extends along the width direction of the cabinet 1, it can effectively guide the cold air blown out by the second air vent 22b to the side surface 11b of the inner liner 11 of the refrigerator. In other words, by providing the light guide plate 223 on the cover plate 22, on the one hand, the light from the lighting element 23 can be guided, and on the other hand, a side air outlet duct can be formed between the light guide plate 223 and the cover plate 22. The overall structure is more compact, and the light guide plate 223 is reused, making the overall structure of the air guiding structure 2 more compact.

[0154] Furthermore, the light guide plate 223, the lighting element 23, and the mounting part 222 are all provided on the side 221a of the panel, which allows most of the space on the panel 221 to be used for setting up the air vent, preventing interference with the air outlet.

[0155] In some embodiments, the light guide plate 223 is arranged parallel to the width direction of the housing 1.

[0156] For example, when light is directed out along the light guide plate 223 parallel to the width direction of the cabinet 1, cold air is also guided from the second air outlet 22b through the light guide plate 223 to the side surface 11b of the refrigerator inner liner 11. Setting the light guide plate 223 parallel to the width direction of the cabinet 1 enables the light to be directed toward the side surface 11b of the refrigerator inner liner 11, so as to prevent direct irradiation to the user side, while also effectively guiding the cold air to the side surface 11b of the refrigerator inner liner 11 to cool the space near the side surface 11b of the refrigerator inner liner 11.

[0157] Please see Figure 11 and Figure 13 In some embodiments, the light plate is tilted relative to the width direction of the housing 1, and the tilt angle of the light guide plate 223 is β, where β is 30°-60°.

[0158] For example, β can be 30°-35°, 35°-40°, 40°-45°, 45°-50°, 50°-55°, 55°-60°, etc. For instance, β can be 30°, 33°, 35°, 37°, 40°, 43°, 45°, 47°, 50°, 53°, 55°, 57°, or 60°, etc.

[0159] When setting the light guide plate 223 in this application, the light guide plate 223 can be tilted, for example, the tilt angle β of the light guide plate 223 can be 30°-60°. On the one hand, when β < 30°, the tilt angle of the light guide plate 223 is small, and some of the light that shines on the light guide plate 223 is easily reflected back to the lighting element 23, affecting the lighting effect of the lighting element 23. On the other hand, when β > 60°, the light guide plate 223 will be more biased towards the depth direction of the housing 1, and some light will easily be emitted along the light guide plate 223 into the depth direction of the housing 1, resulting in more light shining on the user side, affecting the user's use.

[0160] It is understood that the light guide plate 223 can be integrally formed with the panel 221 or installed separately, and this application does not make specific limitations here.

[0161] The refrigerator disclosed in the embodiments of this application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the refrigerator of this application and its core ideas. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
