[0002] Most refrigerator lighting relies on the surface light source of the refrigeration air duct or the top LED lighting, which is fixed in position and cannot illuminate the inside of the drawer, especially the freezer compartment. Most freezer compartments have no lighting, and the internal space is not illuminated after the drawer is pulled out, which causes inconvenience to users. In order to facilitate lighting, a new lighting device is added inside the drawer, and the new lighting device needs to rely on the main power cord for power supply. The refrigerator power supply is led from the back to the two sides of the inner tank. The structure has a separate wiring and a long wiring distance. At present, there is also a self-generating drawer lighting solution. The power generation principle is that the drawer is pulled out to drive the size to rotate the bearing to generate electricity, and the electricity is used for the drawer lighting. Because this solution needs to do work to generate electricity, it needs to use more force to pull the drawer, which affects the user experience of pulling out the drawer, and the single power generation is small and cannot meet the use of lighting. This makes the current drawer lighting power supply complicated, and there is no simple and feasible power supply method. Summary of the invention

[0036] In order to provide a further understanding of the purpose, structure, features, and functions of the present application, the following detailed description is given in conjunction with the embodiments.

[0037] In view of the problem of complex lighting power supply of the above drawer 1, the present application provides a refrigerator, including a box body and a door body 2 connected to the box body opening. The refrigerator box body is used to store food and keep it fresh, and the door body 2 is connected to the box body opening to open and close the refrigerator to maintain the closed environment inside the box. The inner wall of the door body 2 is provided with a wireless charging module 21, and the box body is provided with a lighting module 31;

[0038] The refrigerator is configured such that, when the door 2 is closed, the wireless charging module 21 contacts the lighting module 31 and can charge the lighting module 31 .

[0039] In the present application, the wireless charging module 21 is disposed on the inner wall of the door body 2 , and can be disposed at a position of the inner wall close to the edge of the door body 2 , or at a position far from the edge of the door body 2 .

[0040] The lighting module 31 is arranged inside the refrigerator body, specifically, it can be the side of the shelf closer to the door body 2, the front wall of the drawer 1, or other positions in the body where the lighting module 31 can be arranged.

[0041] When the door body 2 is closed, after the wireless charging module 21 contacts the lighting module 31, if the power in the lighting module 31 is insufficient or lower than the threshold, power transmission can be achieved by wireless charging. If the power in the lighting module 31 is sufficient or higher than the threshold, the lighting module 31 will not be charged.

[0042] The refrigerator is configured such that when the door 2 is opened, the lighting module 31 turns on the lighting mode.

[0043] When the door 2 is opened, the contact state between the wireless charging module 21 and the lighting module 31 changes to a non-contact state, triggering the instruction of the lighting module 31 to start the lighting mode. The lighting module 31 enters the lighting mode to provide sufficient lighting for the interior of the refrigerator.

[0044] In one embodiment, a drawer 1 is disposed in the box, and the lighting module 31 is disposed on the front cover of the drawer 1 .

[0045] The refrigerator is provided with a drawer 1 in the box body, and the drawer 1 is used to store food in a classified manner for easy access. The lighting module 31 is arranged on the front cover of the drawer 1 to ensure that the lighting module 31 can provide direct and sufficient lighting for the inside of the drawer 1.

[0046] Specifically, when the drawer 1 is pushed back and the door body 2 is closed, the wireless charging module 21 contacts the lighting module 31, and the wireless charging module 21 charges the lighting module 31. During the charging process, the lighting mode of the lighting module 31 is not turned on. When the door body 2 is opened, the lighting module 31 starts the lighting mode, ensuring that the food inside the drawer 1 can be clearly seen when the drawer 1 is opened.

[0047] The wireless charging module 21 includes a first shell 211 and a signal transmitter 212, a signal converter 213 and a power circuit board 214 which are arranged in the first shell 211 and connected in sequence; the signal converter 213 converts the electrical signal of the power circuit board 214 into an electromagnetic wave signal, and transmits it outward through the signal transmitter 212.

[0048] The first shell 211 serves as an external protective structure for the internal components. The power circuit board 214 is the power source of the wireless charging module 21. It receives electrical energy from the refrigerator door 2. The signal converter 213 is responsible for converting the electrical signal provided by the power circuit board 214 into an electromagnetic wave signal suitable for wireless charging. The signal transmitter 212 is responsible for emitting the converted electromagnetic wave signal in the wireless charging module 21.

[0049] Specifically, the signal converter 213 also includes but is not limited to an oscillator, a modulator, etc. to ensure the stability and transmission efficiency of the electromagnetic wave signal. The power circuit board 214 also includes but is not limited to a rectifier circuit, a voltage stabilizing circuit, and a protection circuit, etc.

[0050] The wireless charging module 21 is configured as a module structure covered by a first shell 211, and a groove for accommodating the wireless charging module 21 is set at an appropriate position of the door body 2, thereby improving the versatility and compatibility of the wireless charging module 21 and making its maintenance and replacement more convenient. When the wireless charging module 21 of the door body 2 fails, it is only necessary to replace the first shell 211 and the components arranged therein, without disassembling the entire door body 2.

[0051] The power circuit board 214 is connected to the power line of the door body 2 .

[0052] The door 2 power cord is the main line for transmitting electrical energy inside the refrigerator door 2. It connects the main power supply of the refrigerator with various electrical devices on the door 2, such as the door 2 lighting component, the door 2 display or the door 2 alarm.

[0053] In an optional embodiment, the first housing 211 is provided with a first opening 215 on the rear side wall close to the power circuit board 214 to allow the power circuit board 214 to be connected to the power line of the door body 2. This ensures that the wireless charging module 21 can receive the power from the power supply of the refrigerator door body 2 and convert it into an electromagnetic wave signal suitable for wireless charging.

[0054] The power circuit board 214 is directly connected to the power line of the door body 2, avoiding additional wiring work, reducing the risk of wiring errors and failures, and making the wiring inside the refrigerator more concise and orderly.

[0055] The lighting module 31 includes a second shell 311 and a signal receiver 312, a controller 313 and a battery 314 which are connected in sequence and arranged in the second shell 311. The controller 313 is configured to control the signal receiver 312 to receive the electromagnetic wave signal emitted by the signal transmitter 212 and convert it into an electrical signal to charge the battery 314 when it detects that the power of the battery 314 is lower than a threshold.

[0056] The second shell 311 is a protective structure of the lighting module 31, which is used to protect the internal circuits and components from damage by the external environment. The signal receiver 312 is responsible for receiving the electromagnetic wave signal emitted by the wireless charging module 21. The controller 313 can monitor the power status of the battery 314, and when the power of the battery 314 is lower than the threshold, the controller 313 controls the signal receiver 312 to receive the electromagnetic wave signal and convert it into an electrical signal to charge the battery 314. The battery 314 is the energy source of the lighting module 31 and is used to provide power for the lighting module 31.

[0057] The threshold is set to 70%, 80% or 90% of the full charge of the battery 314 according to actual needs, and this application does not make any specific limitation.

[0058] The lighting module 31 is configured as a module structure including a second shell 311, and a groove for accommodating the lighting module 31 is set at an appropriate position in the box, thereby improving the versatility and compatibility of the lighting module 31 and making its maintenance and replacement more convenient. When a failure occurs in the lighting module 31 in the box, it is only necessary to replace the second shell 311 and the components arranged therein, without disassembling the entire lighting module 31.

[0059] The lighting module 31 further includes an LED light bar 315 connected to the battery 314 , and when the door body 2 is opened, the battery 314 supplies power to the LED light bar 315 .

[0060] Specifically, when the refrigerator door 2 is closed, the lighting module 31 is in standby mode, the LED light strip 315 does not work, and the battery 314 maintains a certain power. When the door 2 is opened, the battery 314 supplies power to the LED light strip 315. The LED light strip 315 turns on the lighting mode when the battery 314 supplies power to provide lighting for the inside of the drawer 1.

[0061] In an optional implementation, a second opening 319 is provided on a side wall of the second housing 311 close to the LED light bar 315 , so that the battery 314 can be connected to the LED light bar 315 through a wire 318 and supply power to the LED light bar 315 .

[0062] In the present application, when the battery 314 is low on power, the lighting module 31 is automatically charged through the wireless charging module 21 without the need for manual charging, thereby improving the ease of use of the lighting module 31.

[0063] The LED light bar 315 is single color or multi-color mixed.

[0064] The monochromatic LED light bar 315 emits a single color of light, such as white, warm white, cool white, etc. Of course, the monochromatic LED light bar 315 can also be a single color, such as red, yellow, green, etc. Relatively speaking, the monochromatic LED light bar 315 has good color consistency and uniform lighting effect. The multicolor LED light bar 315 can be a mixed color LED light bar 315 of red, green, and blue to produce rich color changes. The lighting color can be adjusted according to user preferences or the internal environment of the refrigerator to create a specific atmosphere.

[0065] The front cover of the drawer 1 includes a front cover outer wall 316 and a front cover inner wall 317 . The front cover outer wall 316 and the front cover inner wall 317 are sandwiched to form a receiving cavity. The LED light strip 315 is disposed in the receiving cavity.

[0066] The outer side wall 316 of the front cover is the outward portion of the front cover of the drawer 1. When the door body 2 is closed, the outer side wall 316 of the front cover is closer to the door body 2 than the inner side wall 317 of the front cover. The inner side wall 317 of the front cover is the inward portion of the front cover of the drawer 1, which is in contact with the drawer 1 body or the internal storage cavity of the drawer 1. The outer side wall 316 of the front cover and the inner side wall 317 of the front cover are sandwiched to form an accommodating cavity. The size and shape of the accommodating cavity are set according to the requirements of the LED light strip 315 to ensure that the LED light strip 315 can be firmly installed in the accommodating cavity. Specifically, the LED light strip 315 is arranged in the accommodating cavity along the upper edge of the inner side wall 317 of the front cover.

[0067] In an optional implementation, the LED light strip 315 is fixed in the accommodating cavity by an L-shaped fixing frame. Of course, the LED light strip 315 can also be set in the accommodating cavity by other buckle or bolt fixing methods.

[0068] The front cover of the drawer 1 forms an accommodating cavity by sandwiching the front cover outer wall 316 and the front cover inner wall 317 to accommodate the LED light strip 315, thereby realizing hidden lighting without affecting taking out items from the drawer 1.

[0069] The front cover outer wall 316 and the front cover inner wall 317 can be fixed by means of screws, buckles, glue, etc. to achieve a convenient and firm connection.

[0070] In an optional embodiment, in order to allow the light of the LED light strip 315 in the accommodating cavity of the front cover of the drawer 1 to shine out, an opening may be provided in the inner wall 317 of the front cover, or the inner wall 317 of the front cover may be configured with a transparent material.

[0071] The transparent inner wall 317 of the front cover makes the lighting effect of the LED light strip 315 softer and more uniform, and can illuminate every corner inside the refrigerator. The transparent material can include but is not limited to glass, acrylic, plexiglass or transparent plastic.

[0072] The signal transmitter 212 and the signal receiver 312 are both coil structures.

[0073] When alternating current passes through the transmitting coil of the signal transmitter 212, an alternating magnetic field will be generated around it. This magnetic field will change with the change of current, thereby carrying electrical energy information; when the receiving coil of the signal receiver 312 is in the alternating magnetic field generated by the transmitting coil, the receiving coil will generate an induced current under the action of the magnetic field.

[0074] Specifically, the shape, size, number of winding turns and distance between turns of the transmitting coil of the signal transmitter 212 and the receiving coil of the signal receiver 312 are set according to actual needs, and this application does not impose any specific restrictions.

[0075] The battery 314 is a rechargeable battery, such as a sodium ion battery, a nickel-metal hydride battery or a lithium battery. In an optional embodiment, the battery 314 provided in the lighting module 31 is a lithium battery. Lithium batteries have the advantages of high energy density, long cycle life, low self-discharge rate, etc.

[0076] The present application further provides a refrigerator lighting component control method, comprising the following steps:

[0077] S1: Determine whether the wireless charging module disposed on the refrigerator door is in contact with the lighting module disposed in the box body. If so, proceed to step S2; if not, repeat step S1;

[0078] S2: determining whether the lighting module needs to be charged, if yes, proceeding to step S3, if no, returning to step S1;

[0079] S3: Charging the lighting module.

[0080] It is detected in real time whether the wireless charging module 21 set in the door body 2 is in contact with the lighting module 31 set in the box. If so, it is determined that the lighting module 31 needs to be charged, and the lighting module 31 is charged. If it is determined that the lighting module 31 does not need to be charged, it is continued to detect whether the wireless charging module 21 set in the door body 2 is in contact with the lighting module 31 set in the box; if it is determined that the wireless charging module 21 set in the door body 2 is not in contact with the lighting module 31 set in the box, it is continued to detect whether the wireless charging module 21 is in contact with the lighting module 31.

[0081] Step S2 determines whether the lighting module 31 is charged, including detecting whether the power of the battery 314 in the lighting module 31 is lower than a threshold value. If the power of the battery 314 is lower than the threshold value, it is determined that the lighting module 31 needs to be charged; otherwise, if the power of the battery 314 is not lower than the threshold value, it is determined that the lighting module 31 does not need to be charged.

[0082] The threshold is set to 70%, 80% or 90% of the full charge of the battery 314 according to actual needs, and this application does not make any specific limitation.

[0083] In other optional embodiments, if it is detected that the wireless charging module 21 provided in the door body 2 is not in contact with the lighting module 31 provided in the box body, the lighting mode of the lighting module 31 may be turned on.

[0084] The present application relates to a refrigerator and a control method for a refrigerator lighting assembly. The refrigerator includes a box body and a door body 2 connected to the box body opening. The inner wall of the door body 2 is provided with a wireless charging module 21, and a lighting module 31 is provided in the box body. The refrigerator is configured such that when the door body 2 is closed, the wireless charging module 21 contacts the lighting module 31 and can charge it. The lighting module 31 is charged by the wireless charging module 21 without additional wiring, which not only provides sufficient power for the lighting module 31, but also avoids the complicated wiring of wired power supply.
