Description

Technical Field

[0001] The present application relates to the field of refrigeration technology, and more particularly, to a refrigeration device. Background Art

[0002] As a refrigeration device for storage and preservation, the important indicator of a refrigerator is its volume. The larger the volume, the more items can be stored. Currently, a lighting device is generally provided in the storage compartment of a refrigerator to facilitate lighting when the user opens the refrigerator door to pick up or place items. However, the light of the lighting device generally emits light in a direct manner. In order to avoid problems such as bright spots and granularity on the light-emitting surface caused by direct light, the distance between the light source and the light-emitting surface needs to be lengthened. This makes the installation position of the lighting device on the wall of the storage compartment deeper and the thickness of the lighting device thicker, resulting in a smaller effective storage volume of the storage compartment. Summary of the Utility Model

[0003] The purpose of the present application is to provide a refrigeration device that can reduce the thickness of the lighting device, increase the effective storage volume of the storage compartment on the premise that the total volume of the refrigeration device remains unchanged, and has uniform light emission, thereby improving the user experience.

[0004] The present application provides a refrigeration device, including: a storage compartment, including an inner container and a door body covering the inner container; a lighting device, disposed on one side of the wall of the inner container close to the door body. The lighting device includes a lamp holder and a lamp strip. The lamp holder is connected to the wall of the inner container. The lamp holder has a receiving cavity and an opening communicating with the receiving cavity. The lamp strip is disposed in the receiving cavity. The inner wall of the receiving cavity opposite to the lamp strip has a reflecting surface. The light emitted by the lamp strip is reflected at least once by the reflecting surface and then exits from the opening towards the storage compartment. Wherein, the wall of the inner container includes at least one of the top wall and the side wall of the inner container.

[0005] According to the refrigeration device provided by the embodiment of the present application, by disposing the lamp strip in the receiving cavity of the lamp holder and the inner wall of the receiving cavity opposite to the lamp strip having a reflecting surface, the light emitted by the lamp strip is reflected at least once by the reflecting surface and then exits from the opening towards the storage compartment. The reflective light-emitting mode of the lamp strip can fold the light path, shorten the distance between the lamp strip and the light-emitting surface, reduce the thickness of the lighting device, thereby effectively increasing the storage volume of the storage compartment on the premise that the total volume of the refrigeration device remains unchanged, and the light emission of the lighting device is uniform, improving the user experience.

[0006] In addition, according to the refrigeration device of the present application, it may further have the following additional technical features:

[0007] In some embodiments of the present application, an installation groove is provided in the receiving cavity.

The first reflecting portion is adjacent to the lamp strip, the third reflecting portion is adjacent to the opening. A part of the light emitted by the lamp strip reaches the third reflecting portion after being reflected by the first reflecting portion, and is emitted from the opening towards the storage compartment after being reflected by the third reflecting portion. Another part of the light is emitted from the opening towards the storage compartment after being reflected by the first reflecting portion, the second reflecting portion, and the third reflecting portion respectively.

[0011] In some embodiments of the present application, both the first reflecting portion and the third reflecting portion are concave arc surfaces, and the second reflecting portion is arranged parallel to the side wall of the inner container.

Figure 3 is Figure 2 The enlarged structural schematic diagram of area A in

[0034] Referring to Figures 1 to 3 , an embodiment of the present application provides a refrigeration device 100, including a storage compartment 101 and a lighting device 1. The refrigeration device 100 may be, for example but not limited to, devices such as refrigerators, freezers, cold storages, etc.

[0035] The storage compartment 101 includes an inner container 102 and a door body 103 covering the inner container 102. The storage compartment 101 may be a refrigerated compartment of the refrigeration device 100, and the refrigerated compartment includes an inner container 102 and a door body 103 covering the inner container 102. The door body 103 may be a single door body, which is rotatably connected to one side of the inner container 102. The door body 103 may also be two side-by-side door bodies, and the two door bodies are respectively rotatably connected to the corresponding sides of the inner container 102. A variable temperature compartment, a freezing compartment, etc. may also be provided below the storage compartment 101, or only a freezing compartment may be provided below the storage compartment 101.

[0036] The lighting device 1 is disposed on one side of the wall of the inner container 102 close to the door body 103. The lighting device 1 includes a lamp holder 11 and a lamp strip 12. The lamp holder 11 is connected to the wall of the inner container 102. The lamp holder 11 has a receiving cavity 111 and an opening 112 communicating with the receiving cavity 111. The lamp strip 12 is disposed in the receiving cavity 111. The inner wall of the receiving cavity 111 opposite to the lamp strip 12 has a reflecting surface 113. The light emitted by the lamp strip 12 is reflected at least once by the reflecting surface 113 and then exits from the opening 112 towards the storage compartment 101. Wherein, the wall of the inner container 102 includes at least one of the top wall and the side wall of the inner container 102.

[0037] In this embodiment, the lighting device 1 can be disposed on one side of the top wall of the inner container 102 close to the door body 103, or can be disposed on one side of the side wall of the inner container 102 close to the door body 103, or can also be disposed on one side of the top wall and the side wall of the inner container 102 close to the door body 103, for illuminating the storage compartment 101 to facilitate the user to open the door body 103 of the refrigeration device to take and place items. Wherein, "one side of the wall of the inner container 102 close to the door body 103" means that taking the middle part in the depth direction of the inner container 102 as the boundary, the part located on the front side of the middle part is the side close to the door body 103, and the part located on the rear side of the middle part is the side far from the door body 103. For the convenience of description, each embodiment of the present application takes Figure 3 the lighting device 1 shown as an example disposed on the side wall of the inner container 102 for illustration.

[0038] Optionally, the material of the lamp holder 11 can be, for example, polyamide (PA for short) or acrylonitrile-butadiene-styrene copolymer (ABS for short), or can also be a light-transmitting material coated with a light-shielding layer.

[0039] The lamp strip 12 is disposed in the receiving cavity 111. The wall of the receiving cavity 111 opposite to the lamp strip 12 has a reflecting surface 113. As Figure 3 shown by the arrow in, it is the optical path effect diagram of the lamp strip 12. The light emitted by the lamp strip 12 is reflected by the reflecting surface 113 and then exits from the opening 112 towards the storage compartment 101. The number of reflections can be one, two or more. Compared with the technical solution in the related art where the lamp strip emits light in a direct-emission manner, the reflective light-emitting mode of the lamp strip 12 can fold the optical path, shorten the distance between the lamp strip 12 and the light-emitting surface, reduce the thickness of the lighting device 1, and further reduce the installation depth of the lighting device 1 on the wall of the inner container 102, and increase the effective storage volume of the storage compartment 101 on the premise that the total volume of the refrigerator 100 remains unchanged. In addition, the reflective light emission can make the light emission of the lighting device 1 more uniform, improve the problem of granularity, and enhance the user experience.

[0040] According to the refrigeration device 100 provided by the embodiments of the present application, by arranging a light bar 12 in the accommodation cavity 111 of the lamp holder 11, and the inner wall of the accommodation cavity 111 opposite to the light bar 12 has a reflecting surface 113, the light emitted by the light bar 12 is reflected at least once by the reflecting surface 113 and then exits from the opening 112 towards the storage compartment 101. The reflective light-emitting mode of the light bar 12 can fold the optical path, shorten the distance between the light bar 12 and the light-emitting surface, and reduce the thickness of the lighting device 1, so that the effective storage volume of the storage compartment 101 can be increased on the premise that the overall volume of the refrigeration device 100 remains unchanged, and the light emission of the lighting device 1 is uniform, improving the user experience.

[0041] In some embodiments, an installation groove 114 is arranged in the accommodation cavity 111. The light bar 12 includes a circuit board 121 and light-emitting diodes 122 arranged on the circuit board 121. The light bar 12 is installed in the installation groove 114 through the circuit board 121. An installation angle θ is formed between the circuit board 121 and the wall of the inner container 102, and the installation angle θ ≤ 90°.

[0042] The light-emitting diode (Light Emitting Diod, abbreviated as LED) 122 can emit white light, reducing the adverse stimulation of the light on the user's eyes. Optionally, the number of the light-emitting diodes 122 is multiple, and the multiple light-emitting diodes 122 are arranged side by side and at intervals on the circuit board 121. Figure 4 For Figure 3 the structural schematic diagram of the lighting device in

[0043] In some embodiments, the lamp holder 11 includes a first wall 115 and a second wall 116 surrounding the accommodation cavity 111. The first wall 115 is arranged parallel to the wall of the inner container 102. One end of the second wall 116 is connected to the first wall 115. An opening 112 is formed between the end of the second wall 116 far from the first wall 115 and the first wall 115. The installation groove 114 is arranged between the first wall 115 and the second wall 116, and the reflecting surface 113 is formed on the side of the second wall 116 facing the accommodation cavity 111.

[0044] Refer to Figure 4 , the first wall 115 of the lamp holder 11 is arranged parallel to the side wall or the top wall of the inner container 102. The installation groove 114 is arranged between the first wall 115 and the second wall 116. The reflecting surface 113 is formed on the side of the second wall 116 facing the accommodation cavity 111. An opening 112 is formed between the end of the second wall 116 far from the first wall 115 and the first wall 115. Since the installation groove 114 and the opening 112 are both arranged opposite to the second wall 116, all the light emitted by the light bar 12 is reflected by the reflecting surface 113 and then exits from the opening 112, improving the light utilization rate.

[0045] In some embodiments, the installation groove 114 includes a first groove portion 1141 and a second groove portion 1142 which are oppositely arranged. The first groove portion 1141 is formed by extending from one end of the first wall 115 close to the opening 112 towards the accommodation cavity 111, and the second groove portion 1142 is arranged at one end of the second wall 116 connecting the first wall 115.

[0046] As Figure 4 shown, one end of the first wall 115 close to the opening 112 extends towards the accommodation cavity 111 to form the first groove portion 1141, and the second groove portion 1142 is arranged at one end of the second wall 116 connecting the first wall 115. The first groove portion 1141 and the second groove portion 1142 are oppositely arranged to form the installation groove 114 for installing the circuit board 121 of the lamp strip 12. Since the installation groove 114 is arranged close to the first wall 115 parallel to the side wall or the top wall of the inner container 102, the thickness of the lamp socket 11 can be reduced, and the occupied space of the lighting device 1 can be decreased.

[0047] In some embodiments, the reflecting surface 113 includes a first reflecting portion 113a, a second reflecting portion 113b, and a third reflecting portion 113c which are arranged in sequence. The first reflecting portion 113a is adjacent to the lamp strip 12, and the third reflecting portion 113c is adjacent to the opening 112. A part of the light emitted by the lamp strip 12 reaches the third reflecting portion 113c after being reflected by the first reflecting portion 113a, and is emitted from the opening 112 towards the storage compartment 101 after being reflected by the third reflecting portion 113c. Another part of the light is emitted from the opening 112 towards the storage compartment 101 after being reflected by the first reflecting portion 113a, the second reflecting portion 113b, and the third reflecting portion 113c respectively.

[0048] As Figure 3 shown, the light emitted by the lamp strip 12 is emitted from the opening 112 towards the storage compartment 101 after being reflected by the reflecting surface 113 at least once. A part of the light reaches the third reflecting portion 113c after being reflected by the first reflecting portion 113a, and is emitted from the opening 112 after being reflected by the third reflecting portion 113c again. Another part of the light is emitted from the opening 112 after being reflected by the first reflecting portion 113a, the second reflecting portion 113b, and the third reflecting portion 113c respectively. Thus, the light emitted from the opening 112 is relatively uniform, reducing the stimulation of the light to the human eyes.

[0049] In some embodiments, both the first reflecting portion 113a and the third reflecting portion 113c are concave arc surfaces, and the second reflecting portion 113b is arranged parallel to the side wall of the inner container 102. With the reflecting surface 113 arranged in this way, the light emitted by the lamp strip 12 can be reflected to the opening 112 as much as possible, reducing the light loss and improving the light reflectivity of the reflecting surface 113. Optionally, the reflecting surface 113 can also be coated with a reflective layer to further improve the light reflectivity of the reflecting surface 113.

[0050] In some embodiments, a groove 104 is provided on the wall of the inner container 102. A first clamping groove 105 is provided on the side wall of the groove 104 close to the door body 103, and a second clamping groove 106 is provided on the side wall of the groove 104 away from the door body 103. The first wall 115 is provided with a first clamping portion 117 that cooperates with the first clamping groove 105, and a second clamping portion 118 that cooperates with the second clamping groove 106 is provided at one end of the second wall 116 away from the first wall 115.

[0051] As Figure 4 shown, the lighting device 1 is embedded in the groove 104 of the inner container 102 in a snap - connection manner, which can further increase the effective storage space of the storage compartment 101 and is convenient for disassembly and assembly.

[0052] In some embodiments, the lighting device 1 further includes a light - transmitting member 13. The light - transmitting member 13 covers the opening 112. After the light emitted by the light strip 12 is reflected at least once by the reflecting surface 113, it is refracted by the light - transmitting member 13 and then emitted towards the storage compartment 101.

[0053] Optionally, the light - transmitting member 13 is made of a light - transmitting material, and the light - transmitting material can be polycarbonate (PC for short) or acrylic, and the refractive index is generally 1.4 - 1.8. After the light emitted by the light strip 12 is reflected at least once by the reflecting surface 113 and then refracted by the light - transmitting member 13 and emitted towards the storage compartment 101, the emitted light can be weakened, further reducing the irritation of the light to the human eye and improving the user experience.

[0054] In some embodiments, the lamp holder 11 and the light - transmitting member 13 are an integral structural member. The materials of the lamp holder 11 and the light - transmitting member 13 can be the same or different. Optionally, the lamp holder 11 and the light - transmitting member 13 can be made by a two - color one - piece extrusion molding process, which simplifies the assembly process of the lighting device 1, has a simple and stable structure, and is convenient for mass production.

[0055] In some embodiments, the lighting device 1 further includes end caps. The lamp holder forms ports at both ends along the length direction of the light strip 12, and the end caps cover the ports. The end caps can prevent debris and other impurities from entering the lighting device 1. Optionally, the ports abut against the wall of the inner container 102, so that the end caps can be omitted, reducing the number of parts.

[0056] In some embodiments, the number of the lighting devices 1 is two, and the two lighting devices 1 are oppositely arranged on one side of the two side walls of the inner container 102 close to the door body 103. The light emitted by the two lighting devices 1 can fully illuminate all corners of the storage compartment 101, facilitating the user to pick up and place items and improving the use experience.

[0057] It can be understood that the number of the lighting devices 1 can also be other numbers, such as one or three. One lighting device 1 can be arranged on one side of the top wall of the inner container 102 close to the door body 103. Among the three lighting devices 1, two lighting devices 1 can be arranged on the two side walls of the inner container 102, and the other lighting device 1 is arranged on the top wall of the inner container 102. In addition, the two lighting devices 1 can be arranged at intervals on the top wall of the inner container 102, one of the lighting devices 1 is located on one side close to the door body 103, and the other lighting device 1 is located on one side away from the door body 103, or one of the lighting devices 1 is located on one side of the top wall close to one of the side walls, and the other lighting device 1 is located on one side of the top wall close to the other side wall.

[0058] As mentioned above, the above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in the present application should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
