[0002] Fresh-keeping devices such as refrigerators are prone to generating a large amount of unpleasant odors in a closed space due to storing food for a long time. When these odors are mixed, it will cause the flavors of food ingredients to be contaminated, making consumers complain. To solve the problem of flavor contamination, it is necessary to perform odor removal treatment inside the fresh-keeping device. Among them, the intelligent odor removal technology reduces energy consumption while achieving odor removal.

[0003] Intelligent odor removal usually uses an odor sensor to monitor the peculiar smell in the refrigerator, so as to adjust the working parameters of the odor removal module. However, there are problems of different human perception thresholds for food and sensor sensing mismatch when monitoring peculiar smells through the odor sensor. Usually, there will be a situation where the smell is already very unpleasant, but the sensor value is still very low. At the same time, the odor sensor is also easily affected by the temperature, humidity, etc. of the refrigerator, resulting in inaccurate data, which leads to inaccurate control and thus unstable odor removal effect.

[0035] Referring to Figure 1 As shown, an embodiment of the present invention provides a preservation device, which may be a refrigerator or a controlled atmosphere preservation device, etc., an electrical device for preserving food ingredients. The preservation device provided by the embodiment of the present invention includes a deodorization module 110, and the deodorization module 110 is arranged in the internal space of the preservation device for deodorizing the internal space of the preservation device.

[0036] Continuing to refer to Figure 2 As shown, in the embodiment of the present invention, the deodorization module 110 may specifically include an ion field purification module, a high-voltage power supply module, and a fan. At least the ion field purification module of the deodorization module 110 is arranged in the internal space of the preservation device, so that the ion field purification module can act on the air in the internal space of the preservation device to sterilize and purify the air inside the preservation device; the fan is used to provide air circulation flowing through the ion field purification module, and the high-voltage power supply module is used to input the high voltage required for the operation of the ion field purification module to the ion field purification module. Of course, the deodorization module 110 may also include modules with functions such as sterilization and purification, such as a catalytic component, which is not limited herein.

[0037] As shown in the reference Figure 1 and Figure 2 As shown, in some embodiments, the preservation device in the embodiment of the present invention may further include: a weight monitoring device 120, an image recognition device 130, and a controller 140. The weight monitoring device 120 and the image recognition device 130 are both electrically connected to the controller 140, and the controller 140 is also electrically connected to the deodorization module 110. Through the cooperation among the weight monitoring device 120, the image recognition device 130, and the controller 140, the deodorization module 110 is controlled to perform deodorization treatment on the inside of the preservation device.

[0038] Referring to Figure 3 As shown, an embodiment of the present invention provides a deodorization control method for a preservation device, which can be but is not limited to being realized through the cooperation of a weight monitoring device 120, an image recognition device 130, and a controller 140 of the preservation device. The deodorization control method of the preservation device specifically includes the following steps S101 - S103:

[0039] S101. Obtain the information on the degree of peculiar smell of the food ingredients in the preservation device.

[0040] In some embodiments, in step S101, the degree of odor information of the food materials in the preservation device can be obtained based on image recognition technology. Specifically, the following steps S1011 to S1013 can be used to obtain the degree of odor information of the food materials in the preservation device based on image recognition technology:

[0041] First, perform step S1011: Collect images of the food materials in the preservation device.

[0042] Specifically, the preservation device may include a single storage area or multiple spaced storage areas. Based on this, step S1011 specifically includes: performing image acquisition for each storage area in the preservation device to obtain image data of each storage area in the preservation device; preprocessing the image data of each storage area in the preservation device to obtain an image of the food materials in the preservation device.

[0043] It should be understood that the main purpose of preprocessing the image data of each storage area is to eliminate irrelevant information in the image data and enhance information related to the food material part to obtain an image of the food material, which is convenient for accurately identifying the type of food material.

[0044] After obtaining the image of the food materials in the preservation device through the above step S1011, then, perform step S1012: Identify the types of food materials in the preservation device according to the image of the food materials in the preservation device.

[0045] There can be multiple embodiments for identifying the types of food materials in the preservation device:

[0046] In some embodiments, the image of the food materials in the preservation device can be subjected to image recognition through a pre-trained image recognition model to identify the types of food materials in the preservation device.

[0047] In other embodiments, the image of the food materials in the preservation device can be uploaded to the server, and the server compares the image of the food materials in the preservation device with the food material images in the established database to determine the types of food materials in the preservation device.

[0048] After obtaining the types of food materials in the preservation device through the above step S1012, then, perform step S1013: Determine the degree of odor information according to the types of food materials in the preservation device.

[0049] In some embodiments, the degree of odor information can be expressed as the comprehensive odor level of various food materials in the preservation device, and the comprehensive odor level is jointly determined according to the odor levels of each food material in the preservation device.

[0050] Specifically, according to actual needs, the food materials are pre-divided into multiple odor levels according to the degree of odor of the food materials, so as to establish a mapping relationship between the types of food materials and the odor levels. For example, various food materials can be divided into three odor levels: mild odor, moderate odor, and strong odor. Of course, more odor levels can also be divided more finely.

[0051] Since the mapping relationship between the types of food materials and the odor levels is pre-established, the implementation process of step S1013 can be as follows: during the operation of the preservation device, the odor level of each food material in the preservation device can be determined according to the mapping relationship between the types of food materials and the odor levels; and the comprehensive odor level can be determined according to the odor level of each food material in the preservation device.

[0052] For example, in the mapping relationship between the types of food materials and the odor levels, the food materials with mild odor are: apples, bananas,...; the food materials with moderate odor are: mangoes, seafood,...; the food materials with strong odor are: durians, garlic,... If the food materials currently placed in the preservation device are apples and durians, then according to the mapping relationship between the types of food materials and the odor levels, the respective odors of each food material in the preservation device are determined as follows: durian is "strong odor"; apple is "mild odor".

[0053] Specifically, there can be the following multiple implementation methods for determining the comprehensive odor level according to the odor level of each food material in the preservation device:

[0054] In some implementation methods, the highest odor level can be selected from the odor levels of each food material in the preservation device as the comprehensive odor level. For example, if there are food material A with "mild odor", food material B with "moderate odor", and food material C with "strong odor" placed in the preservation device, then the comprehensive odor level is "strong odor".

[0055] In other implementation methods, the comprehensive odor level can be obtained by performing superposition calculation according to the odor levels of each food material in the preservation device. For example, the odor level of each food material can be represented by a numerical value. For example, if there are food material A with an odor level of "1", food material B with an odor level of "2", and food material C with an odor level of "3" placed in the preservation device, then the comprehensive odor level obtained by superposition calculation is "6".

[0056] In the specific implementation process, in combination with Figure 1 and Figure 2 as shown, the above steps S1011 - S1013 can be executed by the image recognition device 120 of the preservation device:

[0057] Refer to Figure 1 and Figure 2As shown, the image recognition device 130 in the embodiment of the present invention includes one or more camera modules 131 for collecting images of the food materials in the preservation device.

[0058] Specifically, the preservation device includes one or more spaced storage areas (for example, Figure 1 the storage areas A, B, and C shown). For each storage area in the preservation device, one or more camera modules 131 are provided. Specifically, for each camera module 131, it can be specifically arranged on the inner wall of the preservation device. Each camera module 131 is used to collect images of the storage area where the camera module 131 is located to obtain the image data of the storage area, so as to realize the image collection of the food materials in the preservation device.

[0059] Refer to Figure 2 As shown, the image recognition device in the embodiment of the present invention further includes an image processor 132, and the image processor 132 is connected to each camera module. First, the image processor 132 is used to receive the image data of the storage area fed back by each camera module 131 and preprocess the image data of each storage area to obtain the image of the food materials in the preservation device; then, the image processor 132 uses a pre-trained image recognition model to perform image recognition on the image of the food materials in the preservation device to identify the types of the food materials in the preservation device. Alternatively, after the image processor 132 obtains the image of the food materials in the large preservation device, it uploads the image to the server, and the server compares the image of the food materials in the preservation device with the food material images in the established database to determine the types of the food materials in the preservation device.

[0060] From the detailed description of step S101 above, it can be seen that the odor degree information of the food materials in the preservation device can be obtained through any of the above embodiments. However, in the embodiment of the present invention, not only the odor degree information of the food materials needs to be obtained, but also step S102 needs to be executed.

[0061] S102. Obtain the weight information of the food materials in the preservation device.

[0062] In some embodiments, in step S102, the weight information of the food materials in the preservation device can be obtained through weight detection technology:

[0063] Specifically, the preservation device may include a single storage area or multiple spaced storage areas. Then step S102 specifically includes: monitoring the weight of the food materials in each storage area in the preservation device to obtain the weight data of the food materials in each storage area in the preservation device; performing a comprehensive weight calculation based on the weight data of the food materials in each storage area in the preservation device to obtain the weight information. It should be understood that the weight information of the food materials obtained in step S102 reflects the total weight of various food materials in the preservation device.

[0064] In the specific implementation process, step S102 can be executed by the weight monitoring device 120 to obtain the weight information of the food materials in the fresh-keeping device through the weight detection technology:

[0065] In the embodiment of the present invention, the storage areas at each interval are separated based on the bearing partition 121. The weight monitoring device 120 includes a weight sensor 122 provided on each bearing partition 121. The weight sensor 122 is used to perform weight monitoring on the food materials in the storage area above the bearing partition 121 to obtain the weight data of the food materials in this storage area. The weight monitoring device 120 further includes a data processor 123. The data processor 123 is connected to each weight sensor 122. The data processor 123 is used to receive the weight data fed back by each weight sensor 122 and perform a summation calculation based on the weight data fed back by each weight sensor 122 to obtain the total weight of various food materials in the fresh-keeping device, that is, the weight information is obtained.

[0066] Of course, in addition to obtaining the weight information of the food materials in the fresh-keeping device through the weight detection technology, the weight information of the food materials in the fresh-keeping device can also be obtained by performing modeling calculations based on the images of the food materials in the fresh-keeping device. Specifically, the area of the food materials in the fresh-keeping device can be calculated according to the images of the food materials in the fresh-keeping device. By inputting the area of the food materials into the area conversion model, the proportion of the storage capacity of the food materials in the fresh-keeping device is calculated, that is, the weight information of the food materials is obtained.

[0067] It should be understood that the above step S101 and step S102 are independent execution steps, and the execution order of step S101 and step S102 is not limited in the actual implementation process. After steps S101 and S102, step S103 is continued:

[0068] S103. Determine the target deodorization mode according to the odor degree information and the weight information.

[0069] In the embodiment of the present invention, the deodorization module is pre-configured with a variety of preset deodorization modes. For each preset deodorization mode, a set of deodorization control parameters for realizing this deodorization mode to control the deodorization module 110 to perform deodorization processing is configured. If the enabled preset deodorization mode is different, the parameter values of the deodorization control parameters for controlling the operation of the deodorization module 110 are different, so that different deodorization modes are enabled, and the deodorization effects generated by the deodorization module in the same time period are different.

[0070] It should be understood that in the implementation of the present invention, the greater the odor degree and the greater the weight of the food materials in the fresh-keeping device, the better the deodorization effect achieved by the enabled target deodorization mode per unit time.

[0071] Specifically, the odor removal control parameters of each preset odor removal mode may include the working voltage when the ion field purification module of the odor removal module is in the enabled state, and the start-stop time ratio of the odor removal module for alternating start and stop operations, etc. Thus, by adjusting the enabled odor removal mode of the odor removal module, the working voltage of the odor removal module and the start-stop time ratio can be adjusted. Because the higher the working voltage of the ion field purification module in the odor removal module and the larger the start-stop time ratio, the higher the odor removal effect generated by the odor removal module per unit time. Therefore, the odor removal treatment of the freshness preservation device by the odor removal module can be controlled more precisely, the odor removal can be adapted to the odor removal requirements, while ensuring the stability of the odor removal effect, the energy consumption waste of the odor removal module is avoided.

[0072] In order to more accurately determine the target odor removal mode adapted to the current odor degree and weight of the food in the freshness preservation device, in some embodiments, step S103 can be implemented through the following steps S1031 - S1032:

[0073] S1031. According to the odor degree information, determine candidate odor removal modes from multiple preset odor removal modes, where the candidate odor removal modes include at least one preset odor removal mode.

[0074] Next, taking the comprehensive odor level as the odor degree information as an example, an implementation manner is given. A mapping relationship between the odor level of the food ingredients and the preset odor removal mode can be established in advance. Specifically, for each pre-divided odor level, a mapping relationship is established between each odor level and at least one preset odor removal mode. The higher the odor level, the better the odor removal effect generated by the mapped odor removal mode per unit time.

[0075] For example, the odor removal module can be pre-configured with the following preset odor removal modes: high-efficiency odor removal mode, ordinary odor removal mode, and energy-saving odor removal mode, and the odor degree of the food ingredients is divided into three odor levels: mild odor, moderate odor, and strong odor. Then, the mapping relationship between the odor level of the food ingredients and the preset odor removal mode can be exemplified as shown in Table 1 below:

[0076] Table 1. Mapping relationship between odor level and preset odor removal mode

[0077] Odor level Preset odor removal mode Severe odor High-efficiency odor removal mode Moderate odor High-efficiency odor removal mode, normal odor removal mode, energy-saving odor removal mode Mild odor Energy-saving odor removal mode

[0078] According to the mapping relationship between the odor level and the preset odor removal mode, each preset odor removal mode mapped by the comprehensive odor level is used as a candidate odor removal mode, where the higher the comprehensive odor level, the better the odor removal effect generated by the mapped odor removal mode per unit time.

[0079] For example, referring to Table 1 above, if the comprehensive odor level obtained through step S101 is "moderate odor", the determined candidate odor removal modes include "high-efficiency odor removal mode", "ordinary odor removal mode", and "energy-saving odor removal mode". If the comprehensive odor level obtained through step S101 is "severe odor", the determined candidate odor removal mode is only the "high-efficiency odor removal mode".

[0080] Since the candidate odor removal modes determined by executing step S1031 may have only one preset odor removal mode or may have multiple preset odor removal modes. If there is only one preset odor removal mode among the candidate odor removal modes, the weight information may not be referred to, and the candidate odor removal mode can be directly selected as the target odor removal mode. If there are multiple preset odor removal modes among the candidate odor removal modes, the weight information obtained in step S102 needs to be used, and by executing step S1032: according to the weight information of the ingredients in the fresh-keeping device, determine the target odor removal mode from the candidate odor removal modes, so as to further match one of the preset odor removal modes from the candidate odor removal modes as the target odor removal mode.

[0081] Specifically, multiple weight ranges can be pre-divided, and a one-to-one mapping relationship can be established in advance between each weight range and M preset odor removal modes. For example, for the high-efficiency odor removal mode, ordinary odor removal mode, and energy-saving odor removal mode mapped to "moderate odor" in Table 1 above, the mapping relationship with the weight range can be established as shown in Table 2 below:

[0082] Table 2. Mapping relationship between weight range and preset odor removal mode

[0083]

[0084]

[0085] Specifically, if the candidate odor removal modes include M different preset odor removal modes, where M is an integer greater than 1, the specific implementation process of step S1032 can be: from M preset weight ranges, determine the target weight range where the weight information is located. Among them, the M preset weight ranges are in one-to-one mapping with the M preset odor removal modes, and the larger the weight range, the higher the odor removal efficiency of the mapped preset odor removal mode; select one of the M different preset odor removal modes mapped to the target weight range as the target odor removal mode.

[0086] In order to determine the target odor removal mode suitable for the odor level and weight of the current food in the fresh-keeping device, in some embodiments, a one-to-one mapping relationship is established in advance between the odor level and the preset odor removal mode, and a one-to-one mapping relationship is established between the preset weight range and the preset odor removal mode. Then step S103 can also be implemented in the following manner:

[0087] S1031’: Determine the first odor removal mode mapped to the comprehensive odor level from multiple preset odor removal modes according to the one-to-one mapping relationship between the odor level and the preset odor removal modes.

[0088] S1032’: Determine the target weight range where the weight information is located from multiple preset weight ranges; and determine the second odor removal mode mapped to the target weight range from multiple preset odor removal modes according to the one-to-one mapping relationship between the preset weight range and the preset odor removal mode.

[0089] S1033’: Compare the first odor removal mode with the second odor removal mode, and select a preset odor removal mode with a better odor removal effect between the first odor removal mode and the second odor removal mode as the target odor removal mode according to the comparison result.

[0090] After determining the target odor removal mode through any implementation manner of step S103, execute step S104: Control the odor removal module to turn on the target odor removal mode, and control the odor removal module to perform odor removal processing on the fresh-keeping device according to the odor removal control parameters of the target odor removal mode.

[0091] According to the odor removal control parameters pre-configured for the target odor removal mode, control the ion field purification module of the odor removal module to work in an alternating start-stop manner. Among them, the odor removal control parameters under different odor removal modes are different, and the start-stop time ratio and / or the working voltage in the enabled state during the start-stop alternating working process of the ion field purification module are different, so the odor removal effect per unit time is different. For example, the odor removal control parameters configured for the odor removal mode can refer to Table 3 below. However, in actual processes, it can be adjusted according to actual needs and is not limited to Table 3 below:

[0092] Table 3. Schematic diagram of odor removal control parameters

[0093] Preset odor removal mode Operating voltage Start-stop time ratio High-efficiency odor removal mode 2500V 1:5 Normal odor removal mode 2000V 1:8 Energy-saving odor removal mode 2000V 1:15

[0094] In terms of the start-stop time ratio, taking the ion field purification module as an example of working in an alternating start-stop manner with a 1-hour cycle, if the start-stop time ratio is 1:5, the ion field purification module alternates in a way of being enabled for 10 minutes and stopped for 50 minutes.

[0095] In the specific implementation process, the above steps S101 to S103 can be executed periodically to update the odor removal mode enabled by the odor removal module 110 in step S104. Alternatively, when it is detected that the user opens the door of the fresh-keeping device, the execution of steps S101 to S103 can be triggered again to update the odor removal mode enabled by the odor removal module 110 in step S104. If the odor removal module 110 is not continuously used, for example, it is enabled once a day, then each time the odor removal module 110 is enabled, the execution of steps S101 to S103 is triggered again to determine the odor removal mode enabled by the odor removal module 110 for the current execution of step S104.
