Abstract
Description
Technical Field
[0001] This application relates to the field of food preservation technology, and in particular to a food preservation device, food preservation method, controller and refrigerator. Background Technology
[0002] As people's demand for stockpiling continues to increase, the requirements for long-term preservation in refrigerators are also rising. Currently, preservation technology mainly relies on precise control of temperature and humidity to extend the shelf life of foods such as fruits, vegetables, and meats. In recent years, the application and research of electromagnetic waves such as electric and magnetic fields in preservation have also been gaining momentum. Oscillating waves are electromagnetic waves generated by LC oscillating circuits. For foods such as fruits and vegetables, oscillating waves can create spatial adversity, exerting stress on the organisms, causing them to rapidly accumulate large amounts of soluble solids, inhibiting respiration, delaying ripening, and increasing sweetness. For meats, oscillating waves inhibit microbial growth, inactivate enzymes, reduce fat oxidation, and retain nutrients by sterilizing and inactivating enzymes.
[0003] However, existing preservation technologies are mostly designed for single food items, such as fruits and vegetables or meat. After the user sets the frequency of the oscillation wave, the compartments in the refrigerator will maintain the set frequency, which may result in some foods not being effectively preserved, failing to meet the preservation needs of different foods, and further leading to a waste of energy and preservation resources.

The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).
[0050] As people's demand for stockpiling continues to increase, the requirements for long-term preservation in refrigerators are also rising. Currently, preservation technology mainly relies on precise control of temperature and humidity to extend the shelf life of foods such as fruits, vegetables, and meats. In recent years, the application and research of electromagnetic waves such as electric and magnetic fields in preservation have also been gaining momentum. Oscillating waves are electromagnetic waves generated by LC oscillating circuits. For foods such as fruits and vegetables, oscillating waves can create spatial adversity, exerting stress on the organisms, causing them to rapidly accumulate large amounts of soluble solids, inhibiting respiration, delaying ripening, and increasing sweetness. For meats, oscillating waves inhibit microbial growth, inactivate enzymes, reduce fat oxidation, and retain nutrients by sterilizing and inactivating enzymes.
[0051] However, existing preservation technologies are mostly designed for single food items, such as fruits and vegetables or meat. After the user sets the frequency of the oscillation wave, the compartments in the refrigerator will maintain the set frequency, which may result in some foods not being effectively preserved, failing to meet the preservation needs of different foods, and further leading to a waste of energy and preservation resources.
[0052] Based on this, this embodiment provides a preservation device, preservation method, controller, and refrigerator. The storage device includes an oscillation wave generator, which can divide the storage device into multiple preservation spaces for placing food. When the oscillation wave generator generates oscillation waves, it can radiate these waves into the preservation spaces, providing an electric field for food preservation. Based on the aforementioned relationship between the oscillation wave generator and the storage device, since different foods may require different electric field strengths, this embodiment determines the operating voltage of the oscillation wave generator based on the food load in different preservation spaces of the storage device. Specifically, it determines the electric field strength required for food preservation in the first and second preservation spaces. Then, based on the operating voltage, the oscillation wave generator is controlled to radiate oscillation waves into the first and second preservation spaces, enabling the oscillation wave generator to generate appropriate oscillation waves according to the food load in the two preservation spaces. This creates corresponding electric fields in the first and second preservation spaces, achieving food preservation in both spaces and simultaneously meeting their preservation requirements.
[0053] The following description, with reference to the accompanying drawings, explains the preservation device, preservation method, controller, and refrigerator:
[0054] Reference Figure 1 As shown, Figure 1 This is a schematic diagram of the preservation device provided in an embodiment of this application.
[0055] In some embodiments, the preservation device includes a storage device 200 and a controller 1000. The storage device 200 includes an oscillation wave generator 300, which can divide the storage device 200 into multiple preservation spaces for placing food. Users can place different food in different preservation spaces for storage. In this embodiment, the oscillation wave generator 300 can generate oscillation waves, which can simultaneously radiate to the multiple preservation spaces divided by the oscillation wave generator 300.
[0056] It is understood that the storage device 200 in the embodiments of this application can be a food storage drawer, a shelf, or other device that can store food, and the embodiments of this application do not impose specific limitations.
[0057] Reference Figure 2 As shown, Figure 2 This is a schematic diagram of the structure of the oscillation wave generator 300 provided in the embodiments of this application.
[0058] In some embodiments, the oscillation wave generator 300 includes a first housing 310, a second housing 320, an electrode plate 330, and a power supply 340. The first housing 310 and the second housing cooperate to form a receiving cavity. The electrode plate 330 and the power supply 340 are disposed in the receiving cavity. The power supply 340 is connected to the power supply interface of the electrode plate 330 to supply power to the electrode plate 330, so that the electrode plate 330 can radiate oscillation waves and form an electric field in the preservation space. Furthermore, the first housing 310 and the second housing are provided to achieve insulation and flame-retardant protection for the oscillation wave generator 300.
[0059] Specifically, in this embodiment, the first housing 310 and the second housing can be combined using structures such as snaps and slots, protrusions and grooves. Correspondingly, the specific structures of the first housing 310 and the second housing can be configured according to the joining method. For example, the first housing 310 may have snaps, and the second housing may have slots corresponding to the snaps, with the snaps and slots engaging to join the first housing 310 and the second housing. Alternatively, the first housing 310 may have protrusions, and the second housing may have grooves corresponding to the protrusions, with the protrusions and grooves engaging to join the first housing 310 and the second housing, and so on. Figure 2 The example shown is that the first housing 310 is provided with a buckle and the second housing is provided with a slot.
[0060] In some embodiments, the power supply 340 of the oscillation wave generator 300 in this application embodiment is an adjustable high-voltage boost power supply. The oscillation wave generator 300 is input with 12V DC power, and then the boost power supply can boost the voltage to 100V to 2000V output, thereby forming a spatial electric field of a certain strength in the space where the electrode plate 330 is located.
[0061] It is understood that the first housing 310 and the second housing in the embodiments of this application can be plastic housing, silicone housing, rubber housing, polycarbonate, etc., and the embodiments of this application do not impose specific limitations.
[0062] In some embodiments, the oscillating wave generator 300 further includes a seal 350 disposed at the connection between the first housing 310 and the second housing, thereby preventing moisture from entering the interior of the oscillating wave generator 300, further avoiding damage to the electrode plate 330 due to moisture, and improving the safety of the oscillating wave generator 300.
[0063] It should be noted that the sealing element 350 in this application embodiment can be a rubber ring, silicone ring, etc., and this application embodiment does not impose specific limitations.
[0064] In some embodiments, the storage device 200 is provided with a mounting groove 210, and the oscillation wave generating device 300 is disposed in the mounting groove 210. The space facing the first housing 310 is the first preservation space, and the space facing the second housing is the second preservation space. Thus, when the oscillation wave generating device 300 generates an oscillation wave, the oscillation wave can simultaneously radiate the first preservation space and the second preservation space separated by the oscillation wave generating device 300.
[0065] Specifically, Figure 1 Taking the example of the mounting groove 210 being located at the bottom of the storage device 200, the mounting groove 210 is positioned parallel to the depth direction of the storage device 200 and is located at the middle position of the length direction of the storage device 200. Figure 1 The oscillation wave generator 300 in the middle has a plate-shaped structure. The oscillation wave generator 300 is mounted on the mounting groove 210 to divide the storage device 200 into two preservation spaces, and the two preservation spaces have the same volume, that is, the first preservation space and the second preservation space have the same volume.
[0066] In some embodiments, the storage device 200 may be provided with multiple mounting grooves 210, such as two, three, etc. When there are two mounting grooves 210, each of the two mounting grooves 210 is provided with an oscillation wave generator 300 to divide the storage device 200 into three preservation spaces. Similarly, when there are three mounting grooves 210, each of the three mounting grooves 210 is provided with an oscillation wave generator 300 to divide the storage device 200 into four preservation spaces. The number of mounting grooves 210 provided in this embodiment is not specifically limited.
[0067] In some embodiments, the controller 1000 is used to determine the operating voltage of the oscillation wave generator 300 according to the food load of the first preservation space and the second preservation space, so as to determine the operating voltage required for food preservation according to the food load of different preservation spaces; and to control the oscillation wave generator 300 to radiate oscillation waves to the first preservation space and the second preservation space according to the operating voltage, so as to simultaneously form an electric field in the first preservation space and the second preservation space, thereby achieving food preservation in the first preservation space and the second preservation space, and simultaneously meeting the preservation needs of the first preservation space and the second preservation space through one oscillation wave generator 300.
[0068] It should be noted that, in the embodiments of this application, the first preservation space and the second preservation space are spaces in the storage device 200 that are separated by the oscillation wave generating device 300, and the food load is the total amount of food stored in the preservation space, such as the weight of the food, the volume of the food, or the quantity of the food, etc.
[0069] Understandably, by adjusting the operating voltage of the oscillating wave generator 300, electric fields of varying strengths can be created. These oscillating wave electric fields can exert a stress effect on fruits and vegetables, thereby regulating their preservation status. Appropriate stress can promote internal metabolism in fruits and vegetables, delay the spoilage process, and improve preservation. Simultaneously, it can inhibit microbial growth in meat products, deactivate enzyme activity, reduce fat oxidation, and retain nutrients.
[0070] It is worth noting that since the field strength changes with the distance between the device and the oscillating wave generator 300, the embodiment of this application determines the size and output voltage of the oscillating wave generator 300 based on simulation and actual measurement to ensure that the space at the farthest point of the storage device 200 is also within the effective oscillating wave radiation range, and further enables comprehensive radiation of the food stored in the storage device 200.
[0071] In some embodiments, the preservation device further includes an infrared sensor, which is set at a preset height position within the preservation space. The infrared sensor is used to trigger a response signal when there is food in the preservation space that is higher than the preset height, thereby determining that the height of the food in the preservation space has reached the preset height.
[0072] It should be noted that if the height of the food in the preservation space is lower than the preset height, the infrared sensor will not trigger a response signal. The preset height position can be set by the user or the height of the storage device 200. Similarly, the detection height threshold (preset height) of the infrared sensor can also be set by the user or the height of the storage device 200. This application embodiment does not impose specific limitations.
[0073] In some embodiments, the preservation device in this application may further include a weight sensor, an ultrasonic sensor, etc. When the preservation device includes a weight sensor, the weight of the food in the preservation space can be sensed in real time, facilitating the determination of the operating voltage of the oscillation wave generator 300 based on different food loads. When the preservation device includes an ultrasonic sensor, the height of the food in the preservation space can be sensed in real time, facilitating the determination of the operating voltage of the oscillation wave generator 300 based on different food loads.
[0074] It will be understood by those skilled in the art that Figure 1-2 The schematic diagrams shown do not constitute a limitation on the embodiments of this application. They may include more or fewer components than shown, or combine certain components, or have different component arrangements. The preservation method in this embodiment will be described in detail below.
[0075] Reference Figure 3 , Figure 3 This is a flowchart illustrating a preservation method provided in this embodiment, which is applicable to, but not limited to, various applications. Figure 1 The preservation device and the preservation method include, but are not limited to, steps S101 to S102.
[0076] Step S101: Determine the operating voltage of the oscillation generator based on the food load of the first and second preservation spaces.
[0077] In step S101 of some embodiments, the food load in different preservation spaces may be different. In this embodiment, the operating voltage of the oscillation wave generator 300 is determined based on the food load in the first and second preservation spaces of the storage device 200, that is, the electric field strength required for food preservation in the first and second preservation spaces is determined, which facilitates the subsequent adjustment of the operating parameters of the oscillation wave generator 300.
[0078] Step S102: Control the oscillation wave generator 300 to radiate oscillation waves to the first and second preservation spaces according to the working voltage.
[0079] In step S102 of some embodiments, the oscillation wave generator 300 is controlled to radiate oscillation waves to the first and second preservation spaces according to the working voltage, so that the oscillation wave generator 300 can generate appropriate oscillation waves according to the amount of food load in the two preservation spaces, thereby forming corresponding electric fields in the first and second preservation spaces, realizing the preservation of food in the first and second preservation spaces, and simultaneously meeting the preservation requirements of the first and second preservation spaces.
[0080] Reference Figure 4 , Figure 4A flowchart illustrating how the food load capacity of the first preservation space is greater than that of the second preservation space is provided in an embodiment of this application. The method includes, but is not limited to, steps S201 to S203.
[0081] Step S201: When the food load capacity of the first preservation space is greater than that of the second preservation space, determine the types of food in the first preservation space.
[0082] In step S201 of some embodiments, the food load in different preservation spaces may be different. Therefore, in this embodiment, the food load in the first preservation space and the food load in the second preservation space are first determined, and then the food load in the two preservation spaces are compared. When the food load in the first preservation space is greater than the food load in the second preservation space, it means that the total amount of food stored in the first preservation space is greater than the total amount of food stored in the second preservation space. At this time, the types of food in the first preservation space are determined, and the main preservation scenario can be determined according to the types of food. Thus, different voltages can be determined according to different scenarios to generate field strengths corresponding to the scenarios, and the optimal parameters required for the preservation space with a higher load can be switched.
[0083] It is worth noting that in this embodiment of the application, the types of food in the first preservation space can be determined by means of image recognition, sensor sensing, etc. For example, a camera is set in the storage device 200, and the camera is used to collect images of the food in the first preservation space, thereby determining the types of food stored in the first preservation space.
[0084] Step S202: If the type of food in the first preservation space is meat, determine that the operating voltage of the oscillation wave generator 300 is the first voltage.
[0085] In step S202 of some embodiments, if the type of food in the first preservation space is meat, since the field strength required for meat preservation is relatively large, the operating voltage of the oscillation wave generator 300 is determined to be the first voltage to inhibit microbial growth, inactivate enzyme activity, and achieve preservation of meat.
[0086] Step S203: If the food in the first preservation space is fruits and vegetables, determine that the operating voltage of the oscillation wave generator 300 is the second voltage.
[0087] In step S203 of some embodiments, if the food in the first preservation space is fruit and vegetable, since the field strength required for the preservation of fruit and vegetable food is relatively small, the working voltage of the oscillation wave generator 300 is determined to be the second voltage. The working voltage of the oscillation wave generator 300 is determined to be the second voltage, so that the soluble solids content in the fruit and vegetable can be accumulated rapidly and a large amount can be accumulated, inhibiting respiration and achieving the preservation of fruit and vegetable food.
[0088] It should be noted that in the embodiments of this application, the first voltage is greater than the second voltage, that is, the field strength generated by the oscillation wave generator 300 radiating the oscillation wave with the first voltage is greater than the field strength generated by the oscillation wave generator 300 radiating the oscillation wave with the second voltage.
[0089] In some embodiments, after comparing the food load capacity of the first preservation space and the food load capacity of the second preservation space, if the food load capacity of the first preservation space is less than that of the second preservation space, it indicates that the total amount of food stored in the first preservation space is less than the total amount of food stored in the second preservation space. In this case, it is necessary to determine the type of food in the second preservation space so that different voltages can be determined according to different scenarios to generate a field strength corresponding to the scenario, and the optimal parameters required for switching to the preservation space with a higher load capacity can be achieved. The specific method for determining the type of food in the second preservation space is the same as steps S202 to S203, and will not be repeated here.
[0090] Reference Figure 5 , Figure 5 A flowchart illustrating how the food load capacity of the first preservation space is equal to that of the second preservation space in an embodiment of this application is provided. The method includes, but is not limited to, step S204.
[0091] Step S204: When the food load in the first preservation space is equal to the food load in the second preservation space, the operating voltage of the oscillation wave generator 300 is determined to be the second voltage.
[0092] In step S204 of some embodiments, when the food load of the first preservation space is equal to the food load of the second preservation space, it means that the total amount of food stored in the first preservation space is similar to the total amount of food stored in the second preservation space. At this time, the scenario with lower field strength is taken as the main preservation scenario, that is, the working voltage of the oscillation wave generator 300 is determined to be the second voltage.
[0093] It is worth noting that when the food load in the first preservation space is equal to the food load in the second preservation space, the embodiment of this application determines that the operating voltage of the oscillation wave generator 300 is a lower voltage, thereby achieving energy saving of the preservation device, avoiding damage to food sensitive to electromagnetic fields, and further maintaining the integrity and freshness of the food.
[0094] Reference Figure 6 , Figure 6 The flowchart of a preservation method provided in another embodiment of this application includes, but is not limited to, steps S301 to S303.
[0095] It should be noted that the preservation device also includes a first infrared sensor and a second infrared sensor. The first infrared sensor is used to trigger a first response signal when there is food in the first preservation space that is higher than a preset height, and the second infrared sensor is used to trigger a second response signal when there is food in the second preservation space that is higher than a preset height.
[0096] Step S301: When the first response signal is received but the second response signal is not received, it is determined that the food load of the first preservation space is greater than the food load of the second preservation space.
[0097] In step S301 of some embodiments, the food in the preservation device is sensed by an infrared sensor. When a first response signal is received but a second response signal is not received, it indicates that the first infrared sensor can sense the food in the first preservation space, that is, the food in the first preservation space has reached the preset height. The second infrared sensor does not sense the food in the second preservation space, that is, the food in the second preservation space may not have reached the preset height, or there may be no food in the second preservation space. At this time, it is determined that the food load of the first preservation space is greater than the food load of the second preservation space, so that the scene of the first preservation space can be used as the main scene in the future, and the voltage can be adjusted to realize the switching of the operating parameters of the oscillation wave generator 300.
[0098] Step S302: When the first response signal and the second response signal are received, determine that the food load of the first preservation space is equal to the food load of the second preservation space.
[0099] In step S302 of some embodiments, when the first response signal and the second response signal are received, it indicates that the first infrared sensor can sense the food in the first preservation space, that is, the food in the first preservation space has reached the preset height. Similarly, the second infrared sensor can sense the food in the second preservation space, that is, the food in the second preservation space has also reached the preset height. At this time, it is determined that the food load in the first preservation space is equal to the food load in the second preservation space. Subsequently, a lower voltage can be used as the operating voltage of the oscillation wave generator 300.
[0100] Step S303: When the first response signal is not received but the second response signal is received, it is determined that the food load of the first preservation space is less than the food load of the second preservation space.
[0101] In step S303 of some embodiments, if the first response signal is not received and the second response signal is received, it indicates that the first infrared sensor cannot sense the food in the first preservation space, that is, the food in the first preservation space may not have reached the preset height, or there is no food in the first preservation space. The second infrared sensor can sense the food in the second preservation space, that is, the food in the second preservation space has also reached the preset height. At this time, it is determined that the food load in the first preservation space is less than the food load in the second preservation space, so that the scene of the second preservation space can be used as the main scene in the future, and the voltage can be adjusted to realize the switching of the operating parameters of the oscillation wave generator 300.
[0102] Reference Figure 7 , Figure 7 The flowchart of a preservation method provided in another embodiment of this application includes, but is not limited to, steps S401 to S403.
[0103] It should be noted that the preservation device also includes a first sensing sensor and a second sensing sensor. The first sensing sensor is used to detect the food load in the first preservation space, and the second sensing sensor is used to detect the food load in the second preservation space. The food load is at least one of the weight and height of the food. That is, the first sensing sensor and the second sensing sensor can be a weight sensor or an ultrasonic sensor, etc.
[0104] Step S401: When the sensing value of the first sensor is greater than the sensing value of the second sensor, it is determined that the food load of the first preservation space is greater than the food load of the second preservation space.
[0105] In step S401 of some embodiments, when the sensing value of the first sensor is greater than the sensing value of the second sensor, it is determined that the food load in the first preservation space is greater than the food load in the second preservation space. Specifically, if the first and second sensors are weight sensors, and the weight value sensed by the first sensor is greater than the weight value sensed by the second sensor, it indicates that the food in the first preservation space is heavier than the food in the second preservation space, i.e., the food load in the first preservation space is greater than the food load in the second preservation space. If the first and second sensors are ultrasonic sensors, the first sensor emits ultrasonic waves in the first preservation space. After the ultrasonic waves reach the food, they are reflected. At this time, the first sensor receives the reflected ultrasonic waves and records the ultrasonic wave emission and reception. The time difference between receiving and receiving determines the distance between the first sensor and the food. Then, the first sensor determines the height of the food in the first preservation space based on its setting height and distance in the storage device 200, thus obtaining the sensing value of the first sensor. Similarly, the second sensor determines the distance between itself and the food in the second preservation space by emitting ultrasonic waves. Then, it determines the height of the food in the second preservation space based on its setting height and distance in the second preservation space, thus obtaining the sensing value of the second sensor. If the sensing value of the first sensor is greater than the sensing value of the second sensor, it means that the height of the food in the first preservation space is higher than the height of the food in the second preservation space, thus determining that the food load in the first preservation space is greater than the food load in the second preservation space.
[0106] It is worth noting that when both the first and second sensors are ultrasonic sensors, the sensing value of the first sensor is obtained by combining the distance between the first sensor and the food in the first preservation space with the sensor's height within the first preservation space; that is, the sensing value of the first sensor is the height of the food in the first preservation space. Similarly, the sensing value of the second sensor is obtained by combining the distance between the second sensor and the food in the second preservation space with the sensor's height within the second preservation space; that is, the sensing value of the second sensor is the height of the food in the second preservation space.
[0107] Understandably, after determining that the food load in the first preservation space is greater than that in the second preservation space, the operating voltage of the oscillation wave generator 300 can be determined based on the first preservation space as the main scenario, so that the release intensity of the oscillation wave can be adjusted according to the load of the preservation space.
[0108] Step S402: When the sensing value of the first sensor is less than the sensing value of the second sensor, it is determined that the food load of the first preservation space is less than the food load of the second preservation space.
[0109] In step S402 of some embodiments, when the sensing value of the first sensor is less than the sensing value of the second sensor, it is determined that the food load in the first preservation space is less than the food load in the second preservation space. Specifically, when the first and second sensors are weight sensors, if the weight value sensed by the first sensor is less than the weight value sensed by the second sensor, it indicates that the food in the first preservation space is lighter than the food in the second preservation space, that is, the food load in the first preservation space is less than the food load in the second preservation space. When the first and second sensors are ultrasonic sensors, the specific embodiment of measuring the food height by the first and second sensors in step S401 can be referred to, and will not be repeated here. As can be seen from the measurement methods of the first and second sensors in step 401, the sensing value of the first sensor is the height of the food in the first preservation space, and the sensing value of the second sensor is the height of the food in the second preservation space. If the sensing value of the first sensor is less than the sensing value of the second sensor, it means that the height of the food in the first preservation space is lower than the height of the food in the second preservation space, and it is determined that the food load in the first preservation space is less than the food load in the second preservation space.
[0110] Understandably, after determining that the food load in the first preservation space is less than that in the second preservation space, the operating voltage of the oscillation wave generator 300 can be determined based on the second preservation space as the main scenario, so that the release intensity of the oscillation wave can be adjusted according to the load of the preservation space.
[0111] Step S403: When the sensing value of the first sensor is equal to the sensing value of the second sensor, it is determined that the food load of the first preservation space is equal to the food load of the second preservation space.
[0112] In step S403 of some embodiments, when the sensing value of the first sensor is equal to the sensing value of the second sensor, it is determined that the food load in the first preservation space is equal to the food load in the second preservation space. Specifically, when the first and second sensors are weight sensors, if the weight value sensed by the first sensor is equal to the weight value sensed by the second sensor, it indicates that the weight of the food in the first preservation space is equal to the weight of the food in the second preservation space, that is, the food load in the first preservation space is equal to the food load in the second preservation space. When the first and second sensors are ultrasonic sensors, the specific embodiment of measuring the food height by the first and second sensors in step S401 can be referred to, and will not be repeated here. As can be seen from the measurement methods of the first and second sensors in step 401, the sensing value of the first sensor is the height of the food in the first preservation space, and the sensing value of the second sensor is the height of the food in the second preservation space. If the sensing value of the first sensor is equal to the sensing value of the second sensor, it means that the height of the food in the first preservation space is similar to that in the second preservation space, and the food load in the first preservation space is determined to be equal to the food load in the second preservation space.
[0113] Understandably, after determining that the food load of the first preservation space is equal to the food load of the second preservation space, the operating voltage of the oscillation wave generator 300 can be determined based on the second preservation space as the main scenario, so that the release intensity of the oscillation wave can be adjusted according to the load of the preservation space.
[0114] Reference Figure 8 , Figure 8 The flowchart of a preservation method provided in another embodiment of this application includes, but is not limited to, step S501.
[0115] Step S501: When no response signal is received from the first infrared sensor or the second infrared sensor, the oscillation wave generator 300 is turned off.
[0116] In step S501 of some embodiments, the first infrared sensor is used to trigger a first response signal when there is food in the first preservation space that is higher than a preset height, and the second infrared sensor is used to trigger a second response signal when there is food in the second preservation space that is higher than the preset height. If no response signal is received from either the first or second infrared sensor, it indicates that the first infrared sensor has not detected food in the first preservation space, meaning the food in the first preservation space has not reached the preset height or no food is placed in the first preservation space. Similarly, if the second infrared sensor has not detected food in the second preservation space, it indicates that the food in the second preservation space has not yet reached the preset height or no food is placed in the second preservation space. In this case, it is not necessary to turn on the oscillation wave generator 300 to generate an electric field; the oscillation wave generator 300 can be directly turned off, thereby achieving energy saving for the preservation device.
[0117] To further explain the preservation device, preservation method, controller, and refrigerator provided in this embodiment, specific examples are given below.
[0118] Example 1:
[0119] Example 1 Figure 1 Taking a preservation device as an example, the preservation device includes a storage device 200, an oscillation wave generator 300, and a controller 1000.
[0120] The oscillation wave generator 300 in this example is suitable for two main scenarios: meat and fruit and vegetable. Therefore, the gear switching can be done in either automatic or manual mode depending on the scenario.
[0121] It should be noted that the oscillation wave generator 300 consists of a small adjustable high-voltage boost power supply, an electrode plate 330, and a housing. The specific structure is as follows: Figure 2 The oscillation wave generator 300 receives a 12V DC input, which is boosted to 100-2000V by a boost power supply. This output voltage is then used to create a spatial electric field of a certain strength in the left and right spaces via electrode plates 330. Since the optimal electric field strength parameters for preserving vegetables and meat differ, the small boost power supply in this embodiment is adjustable, allowing selection of a setting based on actual conditions. The output value of the boost power supply varies between 100 and 2000V.
[0122] The specific modes are shown in the table below.
[0123] Table 1 Oscillation Wave Preservation Mode
[0124]
[0125] For the automatic switching mode, the preservation mode is automatically switched according to the difference in load between the left and right preservation spaces (the first preservation space and the second preservation space) of the oscillation wave generator 300. The load can be sensed through infrared sensing, weight sensing, ultrasonic sensing, etc., thereby switching to the optimal parameters required for the scenario with a high load.
[0126] This example uses an infrared sensor as an example for illustration, and the specific method is as follows.
[0127] Infrared sensors are installed at a certain height in both the first and second preservation spaces to detect the load on both sides of the oscillation wave generator 300. When the food is plentiful, the stacking height is below the detection range of the infrared sensors, so the sensors do not respond. When the food reaches a certain quantity and the stacking height reaches the infrared sensors, the sensors detect the food and respond. If one side's sensor detects the food and responds while the other side does not, for example, if the infrared sensor in the first preservation space responds while the one in the second preservation space does not, or vice versa, it indicates a significant difference in load between the two spaces. The preservation space with the higher load, indicated by the responding infrared sensor, becomes the primary scenario, and the oscillation wave preservation mode is switched. If both sensors respond simultaneously, the loads are considered similar, and the fruit and vegetable scenario (lower field strength) becomes the primary scenario.
[0128] If the sensor is a weight sensor or an ultrasonic sensor, the primary scenario is the preservation space on the side that responds. If both sensors respond simultaneously, the load on both is considered to be similar, and the fruit and vegetable scenario (lower field strength) is taken as the primary scenario. The specific adjustment process can be found in the operating procedure for infrared sensors, and will not be elaborated upon in this embodiment.
[0129] In addition, users can also manually switch gears to select different scene modes.
[0130] This embodiment of the application can adjust the voltage of the oscillation wave generator 300 by sensing the load of different preservation spaces, and further adjust the release intensity of the oscillation wave, thereby achieving the preservation of food in the storage device 200.

Furthermore, memory 1002 may include high-speed random access memory, and may also include non-transitory memory, such as at least one disk storage device, flash memory device, or other non-transitory solid-state storage device.
