[0050] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0051] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0052] In order to solve the above problem, a method for determining spoiled food in a refrigerator 100 is provided in this embodiment. Figure 1 1 is a flow chart of a method for determining spoiled food in the refrigerator 100, the process comprising the following steps:

[0053] Step S100, obtaining target information in the target space;

[0054] Step S200, determining the food with the shortest shelf life in the target space according to the target information, recording it as the target food, and determining the target position where the target food is located;

[0055] Step S300, determining the operation mode of the refrigerator 100 according to the remaining shelf life of the target food, so as to control the refrigerator 100 to operate in the operation mode.

[0056] Through the above steps, the target information in the target space is first obtained, and then the food with the shortest shelf life in the target space is determined according to the target information, and the food with the shortest shelf life is recorded as the target food, and the target position of the target food is determined, and finally the operation mode of the refrigerator 100 is determined according to the remaining shelf life of the target food, so as to control the refrigerator 100 to operate in the operation mode. The present invention adjusts the refrigerator 100 to the operation mode most suitable for preserving the target food, so as to maximize the storage time of the target food and avoid food waste.

[0057] like Figure 2 As shown, in an exemplary embodiment, the above step S100, obtaining the target information in the target space, can be implemented by the following steps, specifically:

[0058] Step S110, image information of food in the refrigerator 100 is obtained through an image acquisition device. The image acquisition device can take pictures of food in the refrigerator 100 at regular intervals, for example, taking a picture of food in the refrigerator 100 at regular intervals of 5 minutes or 10 minutes. The target image acquisition device can be a camera.

[0059] Step S120, obtaining gas information of food in the refrigerator 100 through a gas collection device. The gas collection device can perform gas detection on the food in the refrigerator 100 at regular intervals, for example, once every 5 minutes or 10 minutes.

[0060] The gas collection device may be an electronic nose, and the gas type detected is VOCs (VOCs is a general term for organic compounds with a saturated vapor pressure greater than 70 Pa at room temperature and a boiling point less than 260°C at normal pressure) emitted by fruits. The method of detecting the maturity of fruits by electronic noses is mainly based on its ability to simulate the human olfactory system, and determines its maturity by detecting the volatile organic compounds (VOCs) released by fruits.

[0061] In an exemplary embodiment, the target gas sensor includes but is not limited to an ethanol sensor and an acetic acid sensor. It should be noted that there are one or more target image acquisition devices and one or more target gas sensors in the refrigerator 100. The target image acquisition device and the target gas sensor are both located inside the refrigerator 100.

[0062] like Figure 3 As shown, in an exemplary embodiment, the above-mentioned determination of the food with the shortest shelf life in the target space according to the target information can be achieved by the following steps, specifically:

[0063] Step S210, identifying target image feature data from the image information. Specifically, the feature data of the food features in the image of the food in the refrigerator 100 taken at the last moment is obtained to obtain a set of feature data of the food features.

[0064] Assuming that the first food is a banana, after the banana is placed in the refrigerator 100, the refrigerator 100 will take a picture of the banana according to a preset time interval, and then obtain images of the banana at multiple times. For example, if the banana is photographed ten times, there will be ten images at different times. The target image features include but are not limited to: color, external contour, whether the surface is smooth and whether there is any attachment, etc.

[0065] Step S220, compare the target image feature data with the reference image feature data, and obtain a first comparison result. The larger the difference between the target image feature data and the reference image feature data, the shorter the remaining shelf life of the food. The smaller the difference between the target image feature data and the reference image feature data, the longer the remaining shelf life of the food. The reference image feature data is the image feature data of the same type of food as the target image in good condition.

[0066] In addition, a plurality of food materials are stored in the refrigerator 100, and the image feature data of each food material is compared with the reference image feature data of the same type of food material, and after each food material is compared, the remaining shelf life of each food material is obtained. Then, the remaining shelf life of each food material is compared, and the food material with the smallest remaining shelf life is output as the first comparison result.

[0067] It should be noted that extracting feature data from an image and comparing the extracted feature data with the reference image feature data to calculate the difference is a prior art known to those skilled in the art, and the related art can be referred to CN114544658A, which will not be described in detail here.

[0068] Step S230, identifying target gas characteristic data from the gas information. For example, the concentration of VOCs emitted by fruits is detected and recorded by an electronic nose. The electronic nose can effectively distinguish different varieties of fruits. The electronic nose can distinguish different varieties of fruits by detecting the response of volatile components of fruits. These volatile components may include compounds such as ethylene, esters, and alcohols. For example, the amount of VOCs gas emitted by fruits at different stages varies.

[0069] Step S240, compare the target gas characteristic data with the reference gas characteristic data, and obtain a second comparison result. Taking apples as an example, the VOCs concentration measured after the spoiled apples are placed in the target space for a period of time is used as the reference gas characteristic data, and the ratio of the current VOCs concentration of the apples to the VOCs concentration of the reference gas characteristic data is calculated. When the ratio is in the range of 0.4-0.6, the corresponding remaining shelf life is greater than 72h; when the ratio is in the range of 0.6-0.8, the corresponding remaining shelf life is greater than 48h and less than 72h; when the ratio is in the range of 0.8-0.9, the corresponding remaining shelf life is less than 48h.

[0070] In this embodiment, the gas characteristic data of each food ingredient is compared with the reference gas characteristic data of the same type of food. After each food ingredient is compared, the remaining shelf life of each food ingredient is obtained, and the remaining shelf life of each food ingredient is compared, and the food ingredient with the smallest remaining shelf life is output as the second comparison result.

[0071] Step S250, determining the food with the shortest remaining shelf life according to the first comparison result and the second comparison result. When the food corresponding to the first comparison result and the food corresponding to the second comparison result are the same food, the food is determined to be the food with the shortest remaining shelf life.

[0072] When the ingredient corresponding to the first comparison result and the ingredient corresponding to the second comparison result are not the same ingredient, the process returns to step S100.

[0073] That is to say, it is necessary to determine that this food is the target food when both the image recognition result and the gas recognition result identify this food as the food with the shortest remaining shelf life.

[0074] like Figure 4 As shown, in an exemplary embodiment, the above step 300 determines the operation mode of the refrigerator 100 according to the remaining shelf life of the target food, so as to control the refrigerator 100 to operate in the operation mode, which can be achieved by the following steps, specifically:

[0075] Step S311, if the remaining shelf life is greater than the first time threshold, control the refrigerator 100 to operate in the first fresh-keeping mode. For example, the first time threshold may be 72 hours, and if the remaining shelf life of the target food is greater than 72 hours, control the refrigerator 100 to operate in the first fresh-keeping mode.

[0076] Step S312, controlling the display panel corresponding to the target space to display a first graphic, the first graphic including a plurality of first decorative graphics. The display panel may be a PDLC transparent display screen, and the display panel may be arranged on the front side of the drawer of the refrigerator 100, so that the user can see the operating information of the display panel of the drawer while also seeing the food in the drawer through the PDLC transparent screen, thereby more intuitively understanding the freshness of the food.

[0077] like Figure 5 As shown, in an exemplary embodiment, the above step S300 determines the operation mode of the refrigerator 100 according to the remaining shelf life of the target food to control the refrigerator 100 to operate in the operation mode, which can also be achieved by the following steps, specifically:

[0078] Step S321: If the remaining shelf life is less than the first time threshold and greater than the second time threshold, the refrigerator 100 is controlled to operate in the second fresh-keeping mode. For example, the second time threshold may be 48 hours. When the remaining shelf life of the target food is less than 72 hours and greater than 48 hours, the refrigerator 100 is automatically adjusted to operate in the second fresh-keeping mode.

[0079] Step S322, controlling the display panel corresponding to the target space to display a second graphic, where the second graphic includes a plurality of second decorative graphics;

[0080] Step S323, determining a second decorative graphic that is closest to the target position where the target food is located among the plurality of second decorative graphics, and recording it as a second indication graphic;

[0081] Step S324, controlling the second indication graphic to flash.

[0082] In an exemplary embodiment, the above step S300, according to the remaining shelf life of the target food, determines the operation mode of the refrigerator 100 to control the refrigerator 100 to operate in the operation mode, which can also be achieved by the following steps, specifically:

[0083] Step S325: Control at least a portion of all the first decorative patterns to flash in sequence in a direction close to the second indication pattern.

[0084] Overall, the second indicator graphic on the display panel keeps flashing, and a plurality of first decorative graphics are scattered around the second indicator graphic, some of the first decorative graphics are far from the second indicator graphic, and some of the first decorative graphics are close to the second indicator graphic. According to the distance between the first decorative graphics and the second indicator graphic, the first decorative graphics flash in sequence from far to near, so that the user follows the flashing first decorative graphics and gradually focuses on the second indicator graphics.

[0085] The position of the second indication graphic indicates the position of the target food in the drawer, so that the user can know the approximate position of the target food before opening the drawer according to the display information on the display panel. After opening the drawer, the user can directly take the target food from the corresponding position.

[0086] Moreover, the second indicator graphic and the first decorative graphic can attract the user's attention to a greater extent by displaying information in a manner of continuously flashing. At the same time, the continuously flashing graphics can also strongly express a sense of urgency, which is consistent with the expression method of warning the shelf life of food, so that the user notices that there are remaining ingredients with a short shelf life in the drawer of refrigerator 100, which need to be dealt with by the user in time to prevent food waste.

[0087] like Figure 6 As shown, in an exemplary embodiment, the above step S300 determines the operation mode of the refrigerator 100 according to the remaining shelf life of the target food to control the refrigerator 100 to operate in the operation mode, and also includes:

[0088] Step S331: If the remaining shelf life is less than the second time threshold, the refrigerator 100 is controlled to operate in the third fresh-keeping mode. For example, the second time threshold may be 48 hours. When the remaining shelf life of the target food is less than 48 hours, the refrigerator 100 is automatically adjusted to operate in the second fresh-keeping mode.

[0089] Step S332, controlling the display panel corresponding to the target space to display a third graphic, where the third graphic includes a plurality of third decorative graphics;

[0090] Step S333, determining a third decorative graphic that is closest to the target position where the target food is located among the plurality of third decorative graphics, and recording it as a third indication graphic;

[0091] Step S334, controlling the third indication graphic to flash.

[0092] In an exemplary embodiment, the above step S300, determining the operation mode of the refrigerator 100 according to the remaining shelf life of the target food, so as to control the refrigerator 100 to operate in the operation mode, further includes:

[0093] Step S335, controlling at least a portion of all the first decorative patterns and at least a portion of all the second decorative patterns to flash in sequence in a direction approaching the third indication pattern.

[0094] Overall, the third indication graphic on the display panel keeps flashing, and a plurality of first decorative graphics and a plurality of second decorative graphics are scattered around the third indication graphic. The plurality of first decorative graphics are at different distances from the third indication graphic, and the plurality of second decorative graphics are at different distances from the third indication graphic. According to the distances of the first decorative graphics, the second decorative graphics and the third indication graphic respectively, the first decorative graphics and the second decorative graphics flash in sequence from far to near, so that the user follows the flashing first decorative graphics and the second decorative graphics and gradually focuses on the second indication graphic.

[0095] Those skilled in the art can understand that, when the remaining shelf life of the target food is less than 24 hours, the storage time of the target food is already short, and compared with the second fresh-keeping mode, the food warning level in the third fresh-keeping mode is higher.

[0096] Therefore, on the basis of the third indication pattern flashing to show the location of the target food, the first decorative pattern and the second decorative pattern are flashed in sequence from far to near the third indication pattern. Compared with the second fresh-keeping mode, the third fresh-keeping mode has more flashing decorative patterns, which can fully attract the user's attention and show the urgency of the low remaining shelf life of the target food in the refrigerator 100.

[0097] The temperature of the target space in the second fresh-keeping mode is lower than the temperature in the first fresh-keeping mode, and the temperature of the target space in the third fresh-keeping mode is lower than the temperature in the second fresh-keeping mode.

[0098] In an exemplary embodiment, the display panel is disposed on the front side of the drawer of the refrigerator 100, and a plurality of first decorative graphics, a plurality of second decorative graphics, and a plurality of third decorative graphics are dispersedly distributed on the display panel.

[0099] In an exemplary embodiment, at least one of the first decorative patterns is a pattern that figuratively represents the first fresh-keeping mode. For example, if the first fresh-keeping mode is a treasure mode, at least one first decorative pattern is set to represent a precious food such as ganoderma lucidum, and the other multiple first decorative patterns can be dot-shaped patterns.

[0100] In an exemplary embodiment, when the second fresh-keeping mode is running, the second decorative graphic is in a constant light state. After the position of the target food is determined, the target food is projected onto the display panel on the front side of the drawer along the front-back direction to obtain a projection point of the target food, and the second decorative graphic closest to the projection point of the target food is recorded as the second indication graphic, and the second indication graphic is controlled to flash. That is, the second indication graphic is in a flashing state, and the other second decorative graphics except the second indication graphic are in a constant light state.

[0101] It should be noted that the distance between the first decorative graphic closest to the target position where the target ingredient is located does not refer to the straight-line distance between the target ingredient and the first decorative graphic on the display panel, but the distance between the projection point and the first decorative graphic after the target ingredient is projected along the front-to-back direction onto the display panel on the front panel of the drawer.

[0102] In an exemplary embodiment, three electronic noses are respectively arranged at three different positions in the target space. Since it takes a certain amount of time for the gas emitted by the target food to propagate to the position where the electronic nose is located, the smaller the distance between the target food and the electronic nose, the shorter the time required for the gas to propagate from the target food to the position where the electronic nose is located, so that the gas concentration of the target food detected by the electronic nose closer to the target food changes faster.

[0103] Similarly, the greater the distance between the target food and the electronic nose, the longer it takes for the gas to propagate from the target food to the electronic nose, so that the gas concentration of the target food detected by the electronic nose farther away from the target food changes more slowly.

[0104] The distances between the three electronic noses and the target food are calculated by the differences in the rates of change of the gas concentrations detected by the three electronic noses. The position coordinates of the target food are calculated based on the three distance values ​​and the position coordinates of the three electronic noses.

[0105] In addition, including but not limited to setting three electronic noses at three different positions in the target space, electronic noses may be set at more positions in the target space to improve measurement accuracy.

[0106] In the present invention, the target information in the target space is first obtained. Then, the food with the shortest shelf life in the target space is determined according to the target information, the food with the shortest shelf life is recorded as the target food, and the target position of the target food is determined. Finally, according to the remaining shelf life of the target food, the operation mode of the refrigerator 100 is determined to control the refrigerator 100 to operate in the operation mode, so that the location of the food with the shortest remaining shelf life can be directly indicated to the user, and the refrigerator 100 is adjusted to the operation mode most suitable for storing the food with the shortest remaining shelf life, so as to maximize the storage time of the target food.

[0107] At the same time, after determining the target food, the present invention intuitively displays the location of the target food through the display panel, and guides the user to pay attention to the target food by flashing the graphic. In different preservation modes, the flashing state of the graphic is different. In the first preservation mode, the remaining shelf life of the food is longer, and the first decorative graphic does not flash.

[0108] Furthermore, in the second preservation mode, the remaining shelf life of the food is short. When the second indicator graphic flashes to display the location of the target food, the first decorative graphic flashes in sequence from far to near to guide the user's attention to gradually shift to the location of the second indicator graphic.

[0109] That is to say, in terms of visual effect, the first decorative pattern is in a ring shape (a plurality of first decorative patterns surround the second indication pattern) and gradually shrinks toward the position of the second indication pattern, which makes it very easy for the user to perceive the flashing second indication pattern.

[0110] In addition, the first decorative pattern flashing in sequence from far to near can also express a certain sense of urgency to a certain extent, thereby warning the user to a certain extent that there are foods with a short remaining shelf life in the refrigerator 100.

[0111] Furthermore, in the third preservation mode, the remaining shelf life of the food is the shortest. When the location of the target food is displayed by flashing the third indicator graphic, the user's attention is guided to gradually shift to the location of the third indicator graphic by flashing the first decorative graphic and the second decorative graphic in sequence from far to near.

[0112] That is to say, in terms of visual effect, the first decorative pattern and the second decorative pattern are in a ring shape (a plurality of first decorative patterns and second decorative patterns surround the third indication pattern) and gradually shrink toward the position of the third indication pattern, which makes it very easy for the user to perceive the flashing third indication pattern. In addition, the first decorative pattern and the second decorative pattern flashing sequentially from far to near can also express a sense of urgency to the greatest extent. Since the total number of the first decorative pattern and the second decorative pattern is relatively large, the sequential flashing can alert the user to the greatest extent that there are already ingredients with a short remaining shelf life in the refrigerator 100.
