In order to facilitate users to store food or ingredients in the storage chamber, current refrigerators will be equipped with lighting devices on the upper wall surface of the storage chamber to illuminate the storage chamber. However, the storage chamber of existing refrigerators is generally also provided with a compartment. Therefore, if a lighting device is only provided on the upper wall surface of the storage chamber, it may result in the lighting device only illuminating the uppermost compartment, resulting in poor lighting effect.

[0003] In the related art, a glass plate is attached to the side of the air duct front cover of the refrigerator facing the storage compartment, and a surface light source is arranged in the interlayer between the air duct front cover and the glass plate. In this way, each compartment in the storage compartment can be evenly illuminated by the surface light source, and the lighting effect is better.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] In the related art, the existing refrigerators with surface light sources generally require manual pressing of the glass plate to the air duct front cover. However, when the glass plate is pressed to the air duct front cover manually, the glass plate may not fit tightly to the air duct front cover due to uneven force applied to the glass plate.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0040] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0041] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0042] In order to ensure the lighting effect in the storage room, existing refrigerators generally install surface light sources to evenly illuminate the storage room. In order to ensure the lighting effect and service life of the surface light source, a glass plate is attached to the side of the air duct front cover of the refrigerator facing the storage room, and a surface light source is arranged in the interlayer between the air duct front cover and the glass plate. In this way, the light source can be prevented from being directly exposed, thereby ensuring the service life of the light source.

[0043] When installing the surface light source, it is necessary to first install the surface light source on the front cover of the air duct, then install the glass plate on the front cover of the air duct and stick the glass plate to the front cover of the air duct by using adhesives such as double-sided tape. After sticking the glass plate to the front cover of the air duct, it is necessary to manually press the glass plate to ensure that the glass plate can be firmly stuck to the front cover of the air duct.

[0044] However, when the glass plate is pressed against the front cover of the air duct manually, the glass plate may not fit tightly against the front cover of the air duct due to uneven force applied to the glass plate. At the same time, quality problems may occur due to inaccurate manual pressing positions, which reduces the user experience.

[0045] Combination Figures 1 to 6 As shown, the embodiment of the present disclosure provides a panel pressing device 03. After placing the glass plate 02 and the air duct front cover 01 in the installation area 11, the user can press the glass plate 02 to the air duct front cover 01 through the pressing plate 20 to ensure that the glass plate 02 is evenly stressed, thereby making the glass plate 02 fit tightly to the air duct front cover 01.

[0046] like Figures 1 to 6 As shown, the panel pressing device 03 provided in the embodiment of the present disclosure includes: a base 10, a pressing plate 20 and an elastic element 30. The base 10 is provided with an installation area 11, and a pressing plate 20 rotation shaft 12 is provided on one side of the installation area 11; the pressing plate 20 is rotatably connected to the base 10 through the pressing plate 20 rotation shaft 12; the elastic element 30 includes a first end connected to the base 10 and a second end connected to the pressing plate 20, and the elastic element 30 can push the pressing plate 20 in a direction away from the first end of the elastic element 30; wherein the pressing plate 20 can be rotated in a direction close to the installation area 11 to a pressing position, or rotated in a direction away from the installation area 11 to an open position.

[0047] Specifically, the rotation axis 12 of the pressing plate 20 is disposed on the upper end surface of the base 10 and is located on one side of the mounting area 11, and the pivot edge of the pressing plate 20 is rotatably disposed on the base 10 through the rotation axis 12 of the pressing plate 20. Figure 1 As shown, in the initial state, the pressing plate 20 is in the open position, and the user can first place the air duct front cover 01 on the installation area 11 of the base 10, and then attach double-sided tape to the glass plate 02 and / or the air duct front cover 01, and place the glass plate 02 on the air duct front cover 01. At this time, the elastic element 30 is in a relaxed state and exerts an upward force on the pressing plate 20 to prevent the pressing plate 20 from rotating in a direction close to the installation area 11 under the action of gravity.

[0048] After placing the glass plate 02 on the air duct front cover 01, the user can apply force to the pressing plate 20 so that the pressing plate 20 presses the elastic element 30 and rotates to a pressing position close to the installation area 11, such as Figure 2 At this time, the pressing plate 20 abuts against the glass plate 02 to press the glass plate 02 onto the air duct front cover 01 .

[0049] After the pressing is completed, the user stops applying force to the pressing plate 20, so that the elastic element 30 pushes the pressing plate 20 to rotate to the open position in the direction away from the installation area 11, and then the user can take out the glass plate 02 and the air duct front cover 01 from the installation area 11. In this way, the user can press the glass plate 02 to the air duct front cover 01 through the pressing plate 20 to ensure that the glass plate 02 is evenly stressed, so that the glass plate 02 is closely attached to the air duct front cover 01.

[0050] Optionally, the elastic element 30 is a gas spring. The gas spring is mainly composed of a piston rod, a piston, a sealing guide sleeve, a filler, a pressure cylinder and a joint, wherein the pressure cylinder is a closed cavity filled with an inert gas or an oil-gas mixture, and the pressure in the cavity is several times or dozens of times the atmospheric pressure. When the gas spring is in action, the pressure difference on both sides of the piston is used to achieve the movement of the piston rod. Therefore, the gas spring has the advantages of relatively slow speed, small dynamic force change and easy control, which improves the user experience.

[0051] like Figure 3 and Figure 4 As shown, in some embodiments, the first end of the elastic element 30 is rotatably connected to the base 10 ; the second end of the elastic element 30 is rotatably connected to the pressing plate 20 .

[0052] Specifically, the first end and the second end of the elastic element 30 are rotatably connected to the base 10 and the pressing plate 20, respectively. When the pressing plate 20 is in the open position, the second end of the elastic element 30 is located directly above the first end, so that the elastic element 30 is in a locked state. Figure 3 and Figure 4 In this way, the elastic element 30 can be prevented from rotating under the pressure of the pressing plate 20, so that the elastic element 30 plays a supporting role on the pressing plate 20.

[0053] When the pressing plate 20 rotates toward the pressing position, the elastic element 30 contracts and the second end of the elastic element 30 rotates around the first end toward the mounting area 11. At this time, the upward thrust exerted by the elastic element 30 on the pressing plate 20 gradually decreases to improve the smoothness of the rotation of the pressing plate 20.

[0054] When the pressing plate 20 is rotated to the pressing position, the height of the second end of the elastic element 30 is equal to or lower than the height of the first end, so as to prevent the elastic element 30 from exerting an upward thrust on the pressing plate 20. Figure 1 shown.

[0055] When the pressing plate 20 rotates toward the open position, the elastic element 30 relaxes and the second end of the elastic element 30 rotates around the first end in a direction away from the installation area 11. At this time, the upward thrust exerted by the elastic element 30 on the pressing plate 20 gradually increases to avoid safety hazards caused by excessive force exerted by the elastic element 30 causing the pressing plate 20 to rotate too fast.

[0056] Optionally, the base 10 is provided with a limiting structure corresponding to the first end of the elastic element 30. When the pressing plate 20 rotates to the open position, the limiting structure can limit the first end of the elastic element 30 to prevent the elastic element 30 from rotating.

[0057] like Figures 3 to 5 As shown, in some embodiments, the base 10 is also provided with a mounting base 13, and the first end of the elastic element 30 is rotatably disposed on a mounting surface 132 of the mounting base 13; when the pressing plate 20 is in the pressing position, the height of the pressing plate 20 is lower than the height of the mounting surface 132.

[0058] Specifically, the mounting surface of the mounting base 13 is provided with a base shaft 131, and the first end of the elastic element 30 is rotatably disposed on the mounting surface 132 through the base shaft 131. Figures 3 to 5 shown.

[0059] When the pressing plate 20 is rotated to the pressing position, the height of the pressing plate 20 is lower than the height of the mounting surface 132, that is, the height of the second end of the elastic element 30 is lower than the height of the first end. In this way, after the pressing plate 20 is rotated to the pressing position, the elastic element 30 will apply a downward thrust to the pressing plate 20, that is, the elastic element 30 will push the pressing plate 20 to abut against the glass plate 02. At this time, even if the operator applies force, the pressing plate 20 will continue to output a constant force to the glass plate 02 to ensure that the glass plate 02 can be tightly attached to the air duct front cover 01.

[0060] It is understandable that after the operator determines the pressure threshold that can make the glass plate 02 closely attached to the air duct front cover 01, the operator can select the corresponding elastic element 30 according to the target pressure threshold. In this way, after the pressing plate 20 rotates to the pressing position, the elastic element 30 can apply a pressure greater than or equal to the pressure threshold to the pressing plate 20 so that the pressing plate 20 squeezes the glass plate 02, thereby avoiding the situation where the glass plate 02 cannot be closely attached to the air duct cavity due to insufficient pressure.

[0061] like Figure 4 As shown, optionally, the mounting surface of the mounting base 13 is an inclined surface. When the pressing plate 20 is in the pressed position, the mounting surface includes a first side close to the second end of the elastic element 30 and a second side away from the second end of the elastic element 30. The height of the first side of the mounting surface is lower than the height of the second side. This arrangement can avoid interference between the mounting surface and the elastic element 30 when the elastic element 30 rotates.

[0062] In some embodiments, the mounting base 13 includes: a lower base and an upper base. The lower base is fixedly disposed on the base 10; the upper base is disposed on the lower base and can slide up and down along the lower base.

[0063] Specifically, the lower base is provided with a hollow slide groove structure, and an opening is provided above the slide groove. The upper base is inserted into the slide groove through the opening, and the upper base can slide up and down along the slide groove. In this way, the user can adjust the height of the installation surface according to actual needs.

[0064] like Figure 3 and Figure 5 As shown, in some embodiments, the mounting area 11 is provided with a positioning protrusion 14 , and the positioning protrusion 14 is provided along the edge of the mounting area 11 .

[0065] Specifically, a plurality of positioning protrusions 14 are provided at the edge of the installation area 11, and the plurality of positioning protrusions 14 are evenly arranged. When the pressure plate 20 is in the open position, the user can place the air duct front cover 01 in the installation area 11. At this time, the user can directly abut the edge of the air duct front cover 01 against the positioning protrusions 14, and then directly place the air duct front cover 01 in the installation area 11. With such a configuration, when placing the air duct front cover 01, the user does not need to manually align the air duct front cover 01 with the installation area 11, and the operation is more convenient and efficient.

[0066] like Figure 3 and Figure 5 As shown, in some practical applications, the installation area 11 includes a first edge close to the rotating shaft 12 side of the pressure plate 20 and a second edge adjacent to the first edge; wherein, the first edge and the second edge of the installation area 11 are respectively provided with at least one positioning protrusion 14. In this way, when the user places the air duct front cover 01 on the installation area 11, the positioning protrusion 14 of the first edge can abut against one edge of the air duct front cover 01 to position the air duct front cover 01 in the horizontal direction, and the positioning protrusion 14 of the second edge can abut against the other edge of the air duct front cover 01 to position the air duct front cover 01 in the vertical direction.

[0067] In other practical applications, the installation area 11 includes a first edge close to the rotating shaft 12 side of the pressure plate 20, a second edge adjacent to the first edge, and a third edge opposite to the second edge; wherein, the first edge, the second edge, and the third edge of the installation area 11 are respectively provided with at least one positioning protrusion 14. In this way, when the user places the air duct front cover 01 on the installation area 11, the positioning protrusion 14 of the first edge can abut against one edge of the air duct front cover 01 to position the air duct front cover 01 in the horizontal direction, and the positioning protrusions 14 of the second edge and the third edge can simultaneously abut against the corresponding two edges of the air duct front cover 01 to position the air duct front cover 01 in the longitudinal direction.

[0068] In some embodiments, the positioning protrusion 14 is detachably disposed on the installation area 11 .

[0069] Specifically, a slot is provided at the edge of the installation area 11 corresponding to the positioning protrusion 14, and the user can insert the positioning protrusion 14 into the slot, or pull the positioning protrusion 14 out of the slot. In this way, the user can determine the position of the installation positioning protrusion 14 according to the shape of the air duct front cover 01.

[0070] like Figure 3 and Figure 6 As shown, in some embodiments, the pressing plate 20 is provided with a handle 21 .

[0071] Specifically, a handle 21 is provided on one side or both sides of the pressing plate 20 , and the user can rotate the pressing plate 20 around the rotating shaft 12 of the pressing plate 20 through the handle 21 .

[0072] like Figures 1 to 3 As shown, in some embodiments, the panel pressing device 03 is provided with two groups of elastic elements 30 , and the two groups of elastic elements 30 are arranged on two sides of the base 10 opposite to each other.

[0073] Specifically, when the pressing plate 20 is in the open position, the pressing plate 20 is supported by two sets of elastic elements 30, which can further prevent the pressing plate 20 from rotating in the direction close to the installation area 11 under the action of gravity. When the pressing plate 20 is in the pressed position, the pressing plate 20 is pushed by the two sets of elastic elements 30, which can further increase the force applied by the pressing plate 20 to the glass plate 02, thereby improving the tightness of the glass plate 02 attached to the air duct front cover 01.

[0074] like Figure 6 As shown, in some embodiments, an elastic buffer layer 22 is provided at a position of the pressing plate 20 corresponding to the installation area 11 .

[0075] Specifically, the elastic buffer layer 22 is made of an elastic material. Thus, when the pressing plate 20 presses the glass plate 02 , the elastic buffer layer 22 can prevent the pressing plate 20 from making hard contact with the glass plate 02 , thereby preventing the pressing plate 20 from damaging the glass plate 02 .

[0076] In some embodiments, foam is attached to the position of the pressing plate 20 corresponding to the installation area 11 to form an elastic buffer layer 22 .

[0077] Specifically, the foam is attached to a position of the pressing plate 20 corresponding to the mounting area 11 , and the thickness of the foam is greater than or equal to a preset thickness.

[0078] It can be understood that the elastic buffer layer 22 made of foam is light in weight and has excellent compression deformation resistance and flame retardancy.
