[0042] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application. In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various embodiments. At the same time, the steps or actions in the method description can also be adjusted or reordered in an obvious manner by those skilled in the art. Therefore, the various sequences in the specification and drawings are only for clearly describing a certain embodiment and do not mean that they are necessary sequences, unless it is stated that a certain sequence must be followed.

[0043] In the description of this application, "several" means one or more, "multiple" means more than two. "Greater than", "less than", "exceeding", etc. are understood not to include the original number, and "above", "below", "within", etc. are understood to include the original number. If "first" and "second" are described, they are only used to distinguish technical features and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features or implicitly specifying the sequence of the indicated technical features.

[0044] The serial numbers assigned to components in this article, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. In this application, "connection" and "coupling", unless otherwise specified, both include direct and indirect connection (coupling).

[0045] With the increasing improvement of people's living standards, refrigerators have become essential household items, and people's requirements for the health, hygiene, and safety performance of refrigerators are also getting higher and higher. Early refrigerators only relied on low temperatures to extend the storage period of food. Later, various fresh-keeping technologies for food in the refrigerating chamber were gradually developed. In the fresh-keeping technology of food, appropriate refrigeration environmental conditions can help slow down the growth of bacteria, thereby extending the shelf life of food ingredients. Therefore, the refrigeration environmental conditions inside the refrigerating chamber are one of the factors that must be considered.

[0046] For different types of food ingredients, the appropriate refrigeration environmental conditions may also be different. For example, some vegetables and fruits are more suitable for storage at a higher oxygen concentration, while other food ingredients may require a lower oxygen concentration. Considering the characteristics of food ingredients, the refrigeration environmental conditions in the refrigeration environment should be adjusted according to specific circumstances to ensure that the food ingredients can remain fresh for as long as possible and will not rot prematurely. In addition, the refrigeration environmental conditions factor will also affect the progress of certain chemical reactions in food ingredients. Some food ingredients may be more likely to undergo oxidation reactions or other changes at a high oxygen concentration. Therefore, in daily use, food ingredients with different characteristics are generally placed in the refrigerator drawers with multiple different refrigeration environmental conditions, and special attention needs to be paid to the refrigeration environmental conditions in each refrigerator drawer to maintain the freshness of the food ingredients.

[0047] However, after the existing refrigeration equipment detects the target detection value of the refrigeration environment, it simply displays the target detection value on the display screen of the refrigerator panel. The interface is too monotonous, and the simple numerical display makes it difficult for users to intuitively understand the changes in the internal environment of the refrigerator and the state of the food ingredients.

[0048] Based on this, the embodiments of this application provide a refrigerator, a control method, and a controller, which simulate the refrigeration environment parameters inside the refrigerator through an LED light panel, enhance the beauty and ornamental value of the refrigerator drawer, and achieve the effect of viewing the target detection value inside the refrigerator drawer.

[0049] The following describes a refrigerator, a control method, and a controller provided by an embodiment of the present application with reference to the accompanying drawings:

[0050] Referring to Figure 1 As shown, a refrigerator drawer 100 provided by an embodiment of the present application includes: a drawer main body 110, an accommodation cavity 111 is formed inside the drawer main body 110, a detection device 120 is arranged in the accommodation cavity 111, and the detection device 120 is used to detect a target detection value of the accommodation cavity 111; an LED light panel 130, which includes a plurality of LED lamp beads 131, and the lighting states of the plurality of LED lamp beads 131 are determined according to the target detection value, and the number of the lit LED lamp beads 131 changes with the change of the target detection value.

[0051] It should be noted that the accommodation cavity 111 with a top notch is formed inside the drawer main body 110, and the accommodation cavity 111 is used to store food ingredients. The detection device 120 is installed inside the accommodation cavity 111. The detection device 120 can be an oxygen sensor, a temperature sensor, or a humidity sensor. The target detection value is at least one of oxygen concentration, temperature, and humidity, and the target detection value is measured by using chemical reactions or physical properties. The LED light panel 130 is arranged on one side of the refrigerator drawer 100. A plurality of LED lamp beads 131 are installed inside the LED light panel 130, and the LED lamp beads 131 are fixed on the same plane of the LED light panel 130. The refrigerator drawer 100 can be made of colorless transparent ABS material, and the state of the food ingredients in the refrigerator drawer 100 can be seen clearly when the LED light panel 130 is not activated.

[0052] In an embodiment of the present application, after the user puts in the food ingredients and closes the refrigerator drawer 100, the detection device 120 starts to detect the target detection value in the accommodation cavity 111. The detection device 120 sends relevant data to the controller according to the detected target detection value. The controller decides the number of lit LED lamp beads 131 in the LED light panel 130 according to the high or low target detection value received. For example, when the air humidity in the refrigerator drawer 100 is relatively humid, the controller controls most of the LED lamp beads 131 in the LED light panel 130 to be lit; when the air humidity in the refrigerator drawer 100 is relatively dry, the controller controls only a small part of the LED lamp beads 131 in the LED light panel 130 to be lit. The number of lit LED lamp beads 131 in the LED light panel 130 is positively correlated with the target detection value. When the target detection value is high, the number of lit LED lamp beads 131 will increase, and when the target detection value is low, the number of lit LED lamp beads 131 will decrease. This improves the user's perception of the internal refrigeration environment of the refrigerator drawer 100, enhances the aesthetic appearance of the transparent drawer of the refrigerator, enhances the visualization, brings a sense of freshness, and is more vivid and energetic. After the LED light panel 130 is turned off, the state of the food ingredients in the refrigerator drawer 100 can still be seen through the drawer cabinet body.

[0053] In another embodiment of the present application, an LED lighting panel 130 is installed on multiple refrigerator drawers 100. Without opening the refrigerator drawers 100, the refrigeration environment conditions of each refrigerator drawer 100 can be known according to the refrigeration environment parameters simulated by the LED lighting panel 130, and the user does not need to check the refrigeration environment conditions inside each refrigerator drawer 100 one by one on the refrigerator panel.

[0054] In one embodiment of the present application, through the refrigerator drawer 100 provided by the present application, each refrigerator drawer 100 can determine the number of LED beads 131 lit in the LED lighting panel 130 according to the refrigeration environment of its internal accommodation cavity 111, so as to simulate the refrigeration environment parameters inside the refrigerator drawer 100, making the refrigeration environment conditions of each drawer interior more three-dimensional and clearly visible.

[0055] Refer to Figure 2 and Figure 3 As shown, a refrigerator drawer 100 provided by the present application includes a push-pull panel 140. The LED lighting panel 130 is installed on the push-pull panel 140, or the LED lighting panel 130 serves as the push-pull panel 140 of the drawer body 110. The light emitted when the LED beads 131 are lit can be observed through the push-pull panel 140.

[0056] It can be understood that, in one embodiment of the present application, the drawer cabinet of the refrigerator drawer 100 is formed by five transparent ABS material door panels and one transparent ABS material push-pull panel 140. The LED lighting panel 130 covers the entire surface of the push-pull panel 140. By starting the LED lighting panel 130 through a controller, according to the target detection value of its internal accommodation cavity 111, the number of LED beads 131 lit in the LED lighting panel 130 is determined, so as to simulate the refrigeration environment parameters inside the refrigerator drawer 100; in another embodiment of the present application, the drawer cabinet of the refrigerator drawer 100 is formed by five transparent ABS material door panels and one LED lighting panel 130, where the LED lighting panel 130 serves as one door panel of the drawer cabinet. By starting the LED lighting panel 130 through a controller, according to the target detection value of its internal accommodation cavity 111, the number of LED beads 131 lit in the LED lighting panel 130 is determined, so as to simulate the refrigeration environment parameters inside the refrigerator drawer 100.

[0057] Refer to Figure 4As shown in the figure, a refrigerator 200 provided by an embodiment of the present application includes: a refrigerator 200 includes a detection device 120 for detecting a target detection value of the refrigerator 200, where the target detection value represents at least one dynamically changing parameter during the operation of the refrigerator 200; an LED light panel 130 includes a plurality of LED lamp beads 131, and the lighting states of the plurality of LED lamp beads 131 are determined according to the target detection value, and the number of lit LED lamp beads 131 changes with the change of the target detection value.

[0058] In an embodiment of the present application, after the user puts in the food ingredients and closes the refrigerator 200, the detection device 120 starts to detect the target detection value inside the refrigerator 200. The target detection value is at least one of temperature, humidity, and the continuous operation duration of the compressor. The detection device 120 sends the relevant data to the controller according to the detected target detection value. The controller determines the number of lit LED lamp beads 131 in the LED light panel 130 according to the level of the received target detection value. For example, when the air humidity in the refrigerator 200 is relatively humid, the controller controls most of the LED lamp beads 131 in the LED light panel 130 to be lit; when the air humidity in the refrigerator 200 is relatively dry, the controller controls only a small part of the LED lamp beads 131 in the LED light panel 130 to be lit. The number of lit LED lamp beads 131 in the LED light panel 130 is positively correlated with the target detection value. When the target detection value is higher, the number of lit LED lamp beads 131 will increase, and when the target detection value is lower, the number of lit LED lamp beads 131 will decrease, improving the user's perception of the internal refrigeration environment of the refrigerator 200, enhancing the aesthetic appearance of the transparent drawer of the refrigerator, strengthening the visualization, bringing a sense of freshness, and being more vivid and energetic.

[0059] Refer to Figure 5 and Figure 6 As shown in the figure, a refrigerator 200 provided by the present application includes a refrigerator door panel 210. The LED light panel 130 is installed on the refrigerator door panel 210, or the LED light panel 130 serves as the refrigerator door panel 210 of the refrigerator 200. The light emitted when the LED lamp beads 131 are lit can be observed through the refrigerator door panel 210.

[0060] It can be understood that, in an embodiment of the present application, the LED light panel 130 covers the entire surface of the refrigerator door panel 210. By starting the LED light panel 130 through the controller, according to the target detection value inside the refrigerator 200, the number of LED beads 131 lit in the LED light panel 130 is determined, so as to simulate the refrigeration environment parameters inside the refrigerator 200; in another embodiment of the present application, the refrigerator 200 is formed by five refrigerator door panels 210 and one LED light panel 130, where the LED light panel 130 serves as one of the door panels of the refrigerator 200. By starting the LED light panel 130 through the controller, according to the target detection value inside the refrigerator 200, the number of LED beads 131 lit in the LED light panel 130 is determined, so as to simulate the refrigeration environment parameters inside the refrigerator 200.

[0061] It can be understood that Figures 4 to 6 In the refrigerator 200, there can be multiple refrigerator door panels 210, and the LED light panel 130 can cover only the surface of one refrigerator door panel 210, or can cover the surfaces of some of the refrigerator door panels 210 respectively, or can cover the surfaces of all the refrigerator door panels 210 respectively, which is not limited here.

[0062] Referring to Figure 7 and Figure 8 as shown, Figure 7 There is provided an LED light panel 130 according to an embodiment of the present application Figure 8 There is provided another LED light panel 130 according to an embodiment of the present application. In the embodiment of the present application, the LED light panel 130 further includes a first substrate 134 and a second substrate 135. The first substrate 134 is installed on the push-pull panel 140. The first substrate 134 and the second substrate 135 are light guide plates. A sandwich layer for accommodating the LED beads 131 is formed between the first substrate 134 and the second substrate 135. Alternatively, the refrigerator further includes a first side panel, a second side panel and a bottom plate. The LED light panel 130 further includes a first substrate 134 and a second substrate 135. The first substrate 134 or the second substrate 135 is respectively connected to the first side panel, the second side panel and the bottom plate. The first substrate 134 and the second substrate 135 are light guide plates. A sandwich layer for accommodating the LED beads 131 is formed between the first substrate 134 and the second substrate 135.

[0063] It can be understood that the first substrate 134 and the second substrate 135 are usually made of transparent or translucent materials, such as glass or acrylic. The first substrate 134 and the second substrate 135 are used to provide the functions of supporting and protecting the LED beads 131, and can also serve as a light transmission medium to enable the light to radiate outward from the LED beads 131.

[0064] The sandwich structure is located between the first substrate 134 and the second substrate 135, and is formed by encapsulating the LED lamp beads 131 through the first substrate 134 and the second substrate 135. The sandwich structure protects the LED lamp beads 131 from the external environment, and can also homogenize the light distribution, improve heat dissipation, and maintain the stability and durability of the LED light panel 130.

[0065] In an embodiment of the present application, the first substrate 134 and the second substrate 135 are made of transparent tempered glass. The tempered glass has high hardness and wear resistance, and can resist scratches and abrasions that may occur during daily use, thereby improving the service life of the LED light panel 130; the surface of the tempered glass is smooth and not easy to adhere to dirt, making it easy to clean and keeping the refrigerator 200 clean and tidy; the tempered glass is not easy to get damp and moldy, which helps to keep the interior of the refrigerator 200 dry and clean.

[0066] In an embodiment of the present application, the LED light panel 130 includes a driving board 132 and a carrier film 133. The LED lamp beads 131 are fixed on the carrier film 133 and connected to the driving board 132 through conductive lines.

[0067] It should be noted that the LED light panel 130 includes a driving board 132 and a carrier film 133. The driving board 132 controls the LED lamp beads 131 to light up and emit light through conductive lines, and even adjusts the brightness of the light emitted by the LED lamp beads 131; the carrier film 133 is a bracket for the LED lamp beads 131, carrying the LED lamp beads 131 fixed on it; the conductive line is a circuit path that connects the LED lamp beads 131 to the driving board 132. It may be a metal conductive wire partially printed on the carrier film 133, or a metal wire connected to the carrier film 133 through a connector or welding method. The function of the conductive line is to transmit the current from the driving board 132 to the LED lamp beads 131 to make them emit light.

[0068] In an embodiment of the present application, a PVB film (polyvinyl acetate film) is used as the carrier film 133, which effectively isolates and protects the LED lamp beads 131 and their wires from external environmental interference and damage, ensuring their normal operation and use safety. The LED lamp beads 131 are fixed and separated at specific intervals and arrangements, so that they are arranged in a regular dot matrix pattern, which helps to improve the overall appearance of the LED light panel 130 and the uniformity of light distribution, enabling the LED lamp beads 131 to better exhibit lighting or other functions. In addition, it can absorb and reduce the impact of external shocks and vibrations on the LED lamp beads 131, contributing to improving the durability and reliability of the LED light panel 130 and extending the life of the LED lamp beads 131. Generally speaking, using the PVB film as the carrier film 133 of the LED light panel 130 can provide the functions of protecting, fixing, and regularizing the LED lamp beads 131, and at the same time has good electrical insulation performance and seismic resistance, thereby improving the reliability and service life of the LED light panel 130.

[0069] In another embodiment of the present application, an EVA film (ethylene-vinyl acetate copolymer) is used as the carrier film 133. The LED lamp beads 131 can be firmly adhered to the panel by hot pressing or hot melting, which can ensure that the LED lamp beads 131 will not easily fall off or shift, improving the stability and durability of the LED light panel 130. The EVA film has good transparency, which can allow light to transmit from the LED lamp beads 131 to achieve a uniform lighting effect. At the same time, the EVA film can also provide light scattering and refraction, thereby improving the light distribution and uniformity. In addition, the EVA film usually has excellent ultraviolet resistance and weather resistance, which can effectively prevent the influence of light, ultraviolet rays, and climate factors on the LED light panel 130, thereby extending its service life. Similar to the PVB film, the EVA film can also provide good electrical insulation performance to protect the LED lamp beads 131 and the circuit from external environmental interference and damage. Generally speaking, the EVA film as the carrier film 133 of the LED light panel 130 has multiple functions such as adhesive fixation, light transmittance, ultraviolet resistance and weather resistance, and electrical insulation protection, which can effectively improve the performance and reliability of the LED light panel 130 and is suitable for different lighting and display application scenarios.

[0070] In an embodiment of the present application, the LED light panel 130 further includes a side light source 136, which is arranged at the edge of the first substrate 134 and / or the second substrate 135. The side light source 136 is used to form the background light of the LED lamp beads 131 by guiding light through the first substrate 134 and / or the second substrate 135.

[0071] It should be noted that, in one embodiment, the side light source 136 is disposed on the first substrate 134 and can transmit light to the entire LED light panel through the light guiding effect, thereby achieving uniform light distribution. Through the auxiliary lighting effect of the side light source 136 as the background light, the brightness and luminance of the LED lamp beads 131 are improved. In addition, the side light source 136 can improve the viewing angle of the LED light panel 130, enabling light to be evenly radiated from all angles of the panel. In this way, users can obtain a better visual experience at different viewing angles without worrying about uneven light or brightness issues, making the LED light panel 130 more beautiful and enhancing the visualization.

[0072] In one embodiment of the present application, the side light source 136 adopts a dynamic variable light source. When the LED light panel 130 does not start to display the target detection value inside the refrigerator 200, the side light source 136 is turned on. By changing the color, brightness, and mode of the light source, the dynamic variable light source can create different atmosphere effects. The dynamically changing light source can bring richer and more diverse audio-visual experiences to users, enhancing the viewing experience. At the same time, it can also improve the energy efficiency ratio and environmental performance of the LED light panel 130.

[0073] In the embodiments of the present application, the LED lamp beads 131 are arranged in a regular dot matrix pattern; alternatively, on the surface of the LED light panel 130, a plurality of partitions are sequentially divided along one direction, and the arrangement density of the LED lamp beads 131 changes from large to small along the order of the partitions.

[0074] It can be understood that the arrangement of the LED lamp beads 131 may be arranged according to the representation requirements of the target detection value state. In one embodiment of the present application, the LED lamp beads 131 are arranged in a regular dot matrix pattern, and a certain distance is maintained between each LED lamp bead 131. After determining the number of LED lamp beads 131 to be lit according to the target detection value state, the LED dot matrix is randomly lit according to the number of lit LED lamp beads 131; in another embodiment of the present application, on the surface of the LED light panel 130, a plurality of partitions are sequentially divided along one direction, and the arrangement density of the LED lamp beads 131 changes from large to small along the order of the partitions. After determining the number of LED lamp beads 131 to be lit according to the target detection value state, several partitions of the LED lamp beads 131 are randomly lit according to the number of lit LED lamp beads 131, and the lit part and the unlit part of the LED lamp beads 131 are better regulated through the partitions.

[0075] It should be noted that in this application, the LED lamp beads 131 can also use different colors to represent different ranges of target detection values, or use continuously changing color gradients to represent the changes in target detection values. The spacing between the LED lamp beads 131 may also be affected by the representation requirements to ensure that the changes in the target detection value status can be clearly presented. As those skilled in the art know, with the evolution of technology and the emergence of new application scenarios, the technical solutions provided in the embodiments of this application are equally applicable to similar technical problems.

[0076] Referring Figure 9 as shown Figure 9 is a schematic flowchart of a control method provided by an embodiment of this application. This control method is applied to the refrigerator 200 described above, and this control method may include but is not limited to the following steps:

[0077] Step S910, controlling the detection device to obtain the target detection value information inside the refrigerator drawer;

[0078] Step S920, according to the received target detection value, controlling the number of lit LED lamp beads in the LED light panel.

[0079] In an embodiment of this application, after the user puts in the food ingredients and closes the refrigerator 200, the detection device 120 starts to detect the target detection value inside the accommodation cavity 111. The detection device 120 sends the relevant data to the controller according to the detected target detection value. The controller decides the number of lit LED lamp beads 131 in the LED light panel 130 according to the high or low target detection value received. For example, when the air humidity in the refrigerator 200 is relatively humid, the controller controls most of the LED lamp beads 131 in the LED light panel 130 to be lit; when the air humidity in the refrigerator 200 is relatively dry, the controller controls only a small part of the LED lamp beads 131 in the LED light panel 130 to be lit. The number of lit LED lamp beads 131 in the LED light panel 130 is positively correlated with the target detection value. When the target detection value is high, the number of lit LED lamp beads 131 will increase, and when the target detection value is low, the number of lit LED lamp beads 131 will decrease, improving the user's perception of the internal environmental conditions of the refrigerator 200, enhancing the aesthetic appearance of the transparent drawer of the refrigerator, enhancing the visualization, bringing a sense of freshness, and being more vivid and energetic.

[0080] In another embodiment of this application, by installing the LED light panel 130 on multiple refrigerator drawers 100, the target detection value situation of each refrigerator drawer 100 can be known according to the oxygen concentration value simulated by the LED light panel 130 without opening the refrigerator drawer 100, and the user does not need to check the oxygen situation inside each refrigerator drawer 100 one by one on the refrigerator panel.

[0081] With the refrigerator 200 provided by this application, it is possible to determine the number of lit LED beads 131 in the LED light panel 130 according to the target detection value of its internal accommodation cavity 111, thereby simulating the internal refrigeration environment parameters of the refrigerator 200, making the target detection value of the internal environment of each drawer more three-dimensional and clearly visible.

[0082] Referring Figure 10 as shown Figure 10 is a schematic flowchart of another control method provided by an embodiment of this application. This control method is applied to the refrigerator 200. Among them, the LED beads 131 in the LED light panel 130 are arranged in a regular dot matrix pattern. This control method may include but is not limited to the following steps:

[0083] Step S1010, obtaining the target detection value inside the refrigerator drawer through the detection device;

[0084] Step S1020, randomly selecting and lighting the LED beads corresponding to the number of target detection values.

[0085] In an embodiment of this application, after the user puts in the ingredients and closes the refrigerator 200, the detection device 120 starts to detect the target detection value inside the accommodation cavity 111. The detection device 120 sends the relevant data to the controller according to the detected target detection value, and randomly selects and lights the LED beads 131 corresponding to the target detection value inside the refrigerator 200. For example, if the detected oxygen concentration value is 5%, the controller may randomly select 5% of the LED beads 131 to light up, and randomly light up the LED dot matrix according to the number of lit LED beads 131, simulating the state of oxygen free in the air. After lighting the corresponding number of LED beads 131, the controller will continuously monitor the target detection value inside the refrigerator 200. If it is found that the target detection value is too high or too low, the system will automatically adjust the number of lit LED beads 131 to keep the target detection value and the number of lit LED beads 131 corresponding to each other.

[0086] It should be noted that this control method realizes the visual display of the target detection value inside the refrigerator 200 by dynamically adjusting the number and arrangement dot matrix of the lit and extinguished LED beads 131. The user can understand the situation of the target detection value inside the refrigerator 200 by observing the number of lit LED beads 131.

[0087] Referring Figure 11 as shown Figure 11 is a schematic flowchart of another control method provided by an embodiment of this application. This control method is applied to the refrigerator 200. Among them, a plurality of partitions are sequentially divided along one direction on the surface of the LED light panel 130, and the arrangement density of the LED beads 131 changes from large to small along the order of the partitions. This control method may include but is not limited to the following steps:

[0088] Step S1110, obtain a target detection value inside the refrigerator drawer through a detection device;

[0089] Step S1120, randomly select and light up the LED lamp beads corresponding to the quantity of the target detection value;

[0090] Step S1130, when the obtained target detection value increases, preferentially select a partition with a large arrangement density of LED lamp beads and light up several LED lamp beads;

[0091] Step S1140, when the obtained target detection value decreases, preferentially select a partition with a large arrangement density of LED lamp beads and turn off several LED lamp beads.

[0092] It should be noted that on the surface of the LED light panel 130, a plurality of partitions are sequentially divided along one direction, and the arrangement density of the LED lamp beads 131 changes from large to small along the order of the partitions. The target detection value inside the refrigerator 200 is obtained through the detection device 120. After determining the number of LED lamp beads 131 to be lit according to the state of the target detection value, if the target detection value is relatively high, a larger number of LED lamp beads 131 are selected to be lit; if the target detection value is relatively low, a smaller number of LED lamp beads 131 are selected to be lit, and several LED lamp beads 131 in several partitions are randomly lit according to the number of LED lamp beads 131 to be lit. In this way, by lighting or turning off specific LED lamp beads 131, the state of the target detection value inside the refrigerator 200 can be visually displayed. If the detected target detection value increases, preferentially select a partition with a large arrangement density of LED lamp beads 131 and light up several LED lamp beads 131. Since the arrangement density of the LED lamp beads 131 in this partition is large, the number of LED lamp beads 131 corresponding to this partition is large, and the increase of the target detection value can be more visually displayed. If the detected target detection value decreases, preferentially select a partition with a large arrangement density of LED lamp beads 131 and turn off several LED lamp beads 131. By turning off these LED lamp beads 131, the decrease of the target detection value can be more visually displayed.

[0093] It should be noted that this control method realizes the visual display of the target detection value inside the refrigerator 200 by dynamically adjusting the number and arrangement density of the LED lamp beads 131 to be lit and turned off. The user can understand the situation of the target detection value inside the refrigerator 200 by observing the number of lit LED lamp beads 131.
