Description

Technical Field

[0001] This application relates to the field of refrigerator sterilization technology, and in particular to a refrigerator control method, device, refrigerator compartment, refrigerator equipment and storage medium. Background Technology

[0002] As people's living standards improve, their requirements for food preservation are also increasing. Refrigerators typically use negative ion generators to sterilize and preserve food, thus extending its shelf life. A negative ion generator is a device that generates negative air ions. Negative ions have strong oxidation-reduction capabilities, which can destroy the cell membranes of bacteria or the activity of protoplasmic enzymes, thus playing an antibacterial and bactericidal role. At the same time, they can neutralize positive charges, decompose endogenous ethylene, inactivate enzyme activity, and reduce respiration intensity, thereby slowing down the consumption of nutrients in fruits and vegetables during storage.

[0003] However, low concentrations of negative ions cannot produce a sterilization effect, while high concentrations of negative ions can have an adverse effect on refrigerator components (such as temperature sensors), affecting the normal function of the refrigerator. Summary of the Invention

[0004] This application provides a refrigerator control method, device, refrigerator compartment, refrigerator equipment, and storage medium to solve the problem that existing negative ion generators cause signal interference to temperature sensors, resulting in inaccurate refrigerator temperature control.

[0005] In a first aspect, this application provides a refrigerator control method, the method comprising:

[0006] When the refrigerator door status is detected to switch from open to closed, the negative ion generator in the refrigerator is activated, and the target sterilization mode of the negative ion generator is determined according to the continuous opening time when the door is open, and the negative ion generator is controlled to operate according to the target sterilization mode.

[0007] The target shielding mode of the electromagnetic shielding device in the refrigerator is determined according to the target sterilization mode, and the operation of the electromagnetic shielding device is controlled according to the target shielding mode. The electromagnetic shielding device is located on the outer surface of the temperature sensor in the refrigerator and is used to shield the electromagnetic signals emitted by the negative ion generator to the temperature sensor.

[0008] Secondly, this application provides a refrigerator control device, the device comprising:

[0009] The first control module is used to start the negative ion generator in the refrigerator when the refrigerator door status is detected to switch from open to closed, and to determine the target sterilization mode of the negative ion generator according to the continuous opening time when the door status is open, and to control the operation of the negative ion generator according to the target sterilization mode.

[0010] The second control module is used to determine the target shielding mode of the electromagnetic shielding device in the refrigerator according to the target sterilization mode, and control the operation of the electromagnetic shielding device according to the target shielding mode. The electromagnetic shielding device is located on the outer surface of the temperature sensor in the refrigerator and is used to shield the electromagnetic signals emitted by the negative ion generator to the temperature sensor.

[0011] Thirdly, this application provides a cold storage compartment, the cold storage compartment comprising:

[0012] The main body of the refrigerator compartment;

[0013] A negative ion generator is installed on the inner wall of the refrigerator compartment body to release negative ions for sterilization.

[0014] A temperature sensor is installed on the inner wall of the refrigerator compartment body. The installation position of the temperature sensor is different from that of the negative ion generator on the inner wall of the refrigerator compartment body. The temperature sensor is used to detect the indoor temperature of the refrigerator compartment.

[0015] An electromagnetic shielding device is provided, which covers the outer surface of the temperature sensor to shield the electromagnetic signals generated by the negative ion generator during sterilization.

[0016] Fourthly, this application provides a refrigerator device, which includes the aforementioned refrigerator control device and the aforementioned refrigerator compartment.

[0017] Fifthly, this application also provides a computer storage medium storing computer-executable instructions for executing the above-described refrigerator control method.

[0018] Compared with the prior art, the technical solution provided in this application has the following advantages: The method provided in this application, when detecting that the refrigerator door status has switched from open to closed, indicates that the user has opened the refrigerator door and then closed it again. However, the opening and closing of the door will increase the bacterial content in the refrigerator compartment. Therefore, it is necessary to activate the negative ion generator in the refrigerator for sterilization. The target sterilization mode of the negative ion generator is determined based on the continuous opening time when the door is open, and the negative ion generator is controlled to operate according to the target sterilization mode. During the sterilization process according to the target sterilization mode, the negative ion generator will emit electromagnetic signals to the temperature sensor. To avoid... If the temperature sensor's detection results cause interference, an electromagnetic shield needs to be activated. This electromagnetic shield is located on the outer surface of the temperature sensor within the refrigerator and is used to shield the electromagnetic signals emitted by the negative ion generator to the temperature sensor. A corresponding target shielding mode is determined based on the target sterilization mode, and the electromagnetic shield operates according to this mode. This shields the electromagnetic signals emitted by the temperature sensor when the negative ion generator is operating in the target sterilization mode, reducing the influence of the negative ion generator's signals on the temperature sensor's readings. This ensures the accuracy of the temperature sensor's readings, preventing low accuracy from affecting the refrigerator's normal cooling performance and contributing to food preservation.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0037] Figure 1 This is a diagram illustrating the application environment of a refrigerator control method in one embodiment. (Refer to...) Figure 1 This refrigerator control method is applied to a refrigerator device, which includes a refrigerator compartment and a refrigerator control unit. The refrigerator compartment includes a negative ion generator, an electromagnetic shield, and a temperature sensor. Figure 1 In the diagram, 1 indicates the negative ion generator, 2 indicates the electromagnetic shield, 3 indicates the temperature sensor, and 5 indicates the refrigerator control device. The refrigerator control device is electrically connected to the negative ion generator and the electromagnetic shield, respectively, and is used to control the electromagnetic shield to shield the electromagnetic signal generated by the negative ion generator on the temperature sensor when the negative ion generator is sterilizing.

[0038] Figure 2 This is a schematic diagram of the structure of a refrigerator compartment in one embodiment, the refrigerator compartment comprising:

[0039] The main body of the refrigerator compartment;

[0040] A negative ion generator is installed on the inner wall of the refrigerator compartment body to release negative ions for sterilization.

[0041] A temperature sensor is installed on the inner wall of the refrigerator compartment body. The installation position of the temperature sensor is different from that of the negative ion generator on the inner wall of the refrigerator compartment body. The temperature sensor is used to detect the indoor temperature of the refrigerator compartment.

[0042] An electromagnetic shielding device is provided, which covers the outer surface of the temperature sensor to shield the electromagnetic signals generated by the negative ion generator during sterilization.

[0043] Specifically, the temperature sensor collects temperature and humidity information through a thermistor-made metal temperature probe, which is then converted into a current or voltage signal that is linearly related to the temperature and input to the measurement circuit. The negative ion generator works by using a high-voltage electric field corona discharge. Its inverter circuit generates a strong electromagnetic field. Under the influence of this field, the metal temperature probe and wires of the temperature sensor will generate a considerable induced current. The voltage drop generated by the induced current in the sensor input circuit is superimposed on the useful signal to form an interference signal, which is also sent to the measurement circuit. This causes the temperature sensor to measure an inaccurate temperature, which in turn affects the refrigerator's cooling and is not conducive to food preservation.

[0044] A negative ion generator is installed on the inner wall of the refrigerator compartment body to release negative ions for sterilization; a temperature sensor is also installed on the inner wall of the refrigerator compartment body, in a different position than the negative ion generator, and is used to detect the indoor temperature of the refrigerator compartment; an electromagnetic shield covers the outer surface of the temperature sensor to shield the electromagnetic signals generated by the negative ion generator during sterilization.

[0045] Reference Figure 2 In the diagram, 1 indicates the negative ion generator, and 2 indicates the electromagnetic shielding device. (Refer to...) Figure 3 An electromagnetic shield is installed on the outer surface of the temperature sensor. The target shielding mode of the electromagnetic shield when it is activated corresponds to the target sterilization mode of the negative ion generator when it is activated. When the target sterilization mode of the negative ion generator is the first sterilization mode, the target shielding mode of the electromagnetic shield is the first shielding mode; when the target sterilization mode of the negative ion generator is the second sterilization mode, the target shielding mode of the electromagnetic shield is the second shielding mode; when the target sterilization mode of the negative ion generator is the third sterilization mode, the target shielding mode of the electromagnetic shield is the third shielding mode.

[0046] When the negative ion generator produces electromagnetic signals of different intensities under different sterilization modes, the electromagnetic shielding device set on the outer surface of the temperature sensor can shield the electromagnetic signals according to the corresponding shielding mode. This reduces the influence of the signals emitted by the negative ion generator on the temperature detected by the temperature sensor, ensuring the accuracy of the temperature detection and avoiding the impact of low temperature detection accuracy on the normal cooling effect of the refrigerator, which is beneficial to the preservation of food.

[0047] In one embodiment, the electromagnetic shield includes a fixed baffle assembly and a movable baffle assembly. The center of the movable baffle assembly and the center of the fixed baffle assembly are coaxially arranged. The fixed baffle assembly includes a first fixed baffle. When the rotation angle of the movable baffle assembly is the same as the rotation angle of the first fixed baffle, it is hidden under the first fixed baffle. When the movable baffle assembly is rotated to be fully exposed, it forms a circle with the first fixed baffle.

[0048] Specifically, the electromagnetic shield is composed of a fixed baffle assembly and a movable baffle assembly. The center of the fixed baffle assembly and the center of the movable baffle assembly are coaxially arranged. The fixed baffle assembly cannot rotate along the central axis, while the movable baffle assembly can rotate along the central axis to adjust the rotation angle. The fixed baffle assembly includes a first fixed baffle. Since the movable baffle assembly can be hidden under the first fixed baffle by rotation or form a circle with the first fixed baffle when fully exposed, it means that the shape of the movable baffle assembly is the same as the shape of the first fixed baffle. Fully exposed means that the movable baffle assembly is not blocked by the first fixed baffle. If the first fixed baffle and the movable baffle assembly of the same shape are to form a circle, the first fixed baffle and the movable baffle assembly are composed of sectors formed by dividing the circle into any even number of equal parts. For example, dividing the circle into two equal parts results in both the first fixed baffle and the movable baffle assembly being semicircles; or dividing the circle into four equal parts results in both the first fixed baffle and the movable baffle being composed of two opposing sectors, with the two sectors of the first fixed baffle spaced 90° apart; or dividing the circle into six equal parts results in both the first fixed baffle and the movable baffle being composed of three spaced sectors, with the sectors of the first fixed baffle spaced 60° apart; or dividing the circle into eight equal parts results in both the first fixed baffle and the movable baffle assembly being composed of four spaced sectors, with the sectors of the first fixed baffle spaced 45° apart. And so on, the first fixed baffle can be composed of any number of sectors. Figure 4 As shown in Figure 21, the first fixed baffle is composed of two fan-shaped parts. In this embodiment, the first fixed baffle is an hourglass shape composed of two fan-shaped parts.

[0049] The movable baffle assembly has the same shape as the first fixed baffle. When the movable baffle assembly rotates at the same angle as the first fixed baffle, it overlaps with the first fixed baffle assembly and is hidden beneath it. In this case, the front view of the electromagnetic shield only includes the hourglass-shaped first fixed baffle. When the movable baffle assembly rotates to be perpendicular to the first fixed baffle, the front view of the electromagnetic shield includes a circle formed by the first fixed baffle and the movable baffle assembly.

[0050] In one embodiment, the movable baffle assembly includes a plurality of movable baffles, the movable baffles having the same shape as the first fixed baffle, the movable baffles being hidden under the first fixed baffle when their rotation angle is the same as the rotation angle of the first fixed baffle, and the movable baffles forming a circle with the first fixed baffle when rotated to be fully exposed.

[0051] Specifically, taking the first fixed baffle as an hourglass shape as an example, the shape of each movable baffle is also hourglass-shaped, such as... Figure 4 As shown, when the rotation angle of the movable baffle is the same as the rotation angle of the first fixed baffle, it is hidden under the first fixed baffle, as shown. Figure 6 As shown, when the movable baffle is rotated to be fully exposed, the movable baffle and the first fixed baffle form a circle. Full exposure means that the movable baffle is not blocked by the first fixed baffle, that is, the first fixed baffle and the rotated movable baffle can be displayed. The shielding strength of the electromagnetic shield can be adjusted by rotating out different numbers of movable baffles. The more movable baffles stacked together, the stronger the shielding strength of the electromagnetic shield can be.

[0052] In one embodiment, different movable baffles are provided with vent holes of different diameters. The movable baffles are arranged below the first fixed baffle in order of increasing vent hole diameter. The movable baffles located near the first fixed baffle have the smallest vent hole diameter, while the movable baffles located away from the first fixed baffle have the largest vent hole diameter.

[0053] Specifically, different movable baffles are equipped with vents of different shapes and diameters. Below the first fixed baffle, the vents are arranged in ascending order of diameter, with the smallest vents on the movable baffles closest to the first fixed baffle and the largest on the movable baffles furthest from the first fixed baffle. This is because, when increasing the shielding strength of the electromagnetic shield, the rotation angle is adjusted sequentially from the movable baffle furthest from the first fixed baffle until fully exposed. When the movable baffle closest to the first fixed baffle is fully exposed, it covers the previously rotated movable baffle. By rotating to create movable baffles with different vent diameters and layering them, a multi-layered, porous structure is formed. By continuously rotating to create movable baffles with progressively smaller vent diameters, the shielding capability of the electromagnetic shield can be gradually improved. The shape of the vents on each movable baffle can be any of the following: fence-like, rectangular, rhomboid, strip-shaped, triangular, circular, or irregular polygonal. The shapes of the vents on different movable baffles can be the same or different. The movable baffle is driven to rotate by a rotary motor. The rotary motor drives the movable baffle to rotate to a specified rotation angle according to the received rotation command, so as to switch different shielding modes.

[0054] For example, a movable baffle assembly comprising three movable baffles is illustrated below. These three movable baffles are a first movable baffle, a second movable baffle, and a third movable baffle. (Refer to...) Figure 7 In the diagram, 23 indicates the first movable baffle, 24 indicates the second movable baffle, and 25 indicates the third movable baffle. Mode 1 indicates the first shielding mode, Mode 2 indicates the second shielding mode, Mode 3 indicates the third shielding mode, and Normal mode indicates the default shielding mode. The first movable baffle is located away from the first fixed baffle. The second movable baffle is positioned between the first and third movable baffles, and the third movable baffle is located close to the first fixed baffle. The vent hole on the third movable baffle has the smallest diameter, while the vent hole on the first movable baffle has the largest diameter. The first vent hole is shaped like a fence, while the vent holes on both the second and third movable baffles are circular. In the first shielding mode, the electromagnetic shield rotates out the first movable baffle until it is fully exposed. In the second shielding mode, the electromagnetic shield adjusts the rotation angle of the second movable baffle relative to the first movable baffle. The rotation angles of the baffles are consistent, meaning the second movable baffle rotates out to cover the first movable baffle. Since the diameter of the vent hole on the second movable baffle is smaller than that on the first movable baffle, the aperture can be reduced to improve the shielding effect. In the third shielding mode, the rotation angle of the third movable baffle is adjusted to match that of the second movable baffle, meaning the third movable baffle rotates out to cover the second movable baffle. Since the diameter of the vent hole on the third movable baffle is smaller than that on the second movable baffle, the aperture can be further reduced to further improve the shielding effect. The apertures of the first, second, and third movable baffles decrease sequentially, covering each other in descending order of aperture, with the smaller aperture baffle covering the larger aperture baffle. This allows the shielding mode of the electromagnetic shield to be switched by rotating different numbers of movable baffles.

[0055] In one embodiment, the fixed baffle assembly further includes a second fixed baffle, and the movable baffle assembly is disposed between the first fixed baffle and the second fixed baffle. When the movable baffle assembly is hidden under the first fixed baffle, the first fixed baffle and the second fixed baffle form a circle.

[0056] Specifically, when the movable baffle assembly rotates to full exposure, it obscures the second fixed baffle. In this case, the front view of the electromagnetic shield only shows the circle formed by the first fixed baffle and the movable baffle assembly, and the second fixed baffle is not visible. When the movable baffle assembly rotates and hides under the first fixed baffle, the front view of the electromagnetic shield only shows the circle formed by the first and second fixed baffles. Since the second fixed baffle is located under the first fixed baffle, for the second fixed baffle to form a circle with the first fixed baffle, its shape can be circular or the same / similar to the shape of the first fixed baffle. If the shape of the second fixed baffle is the same as or similar to the shape of the first fixed baffle, the number of sectors formed by the second fixed baffle is the same as the number of sectors formed by the first fixed baffle, but the central angle of each sector of the second fixed baffle is equal to or greater than the first fixed baffle. When the central angles of the constituent sectors of the second fixed baffle are equal to those of the constituent sectors of the first fixed baffle, it indicates that the shape of the second fixed baffle is the same as that of the first fixed baffle. In this case, the second fixed baffle is fully exposed and forms a circle with the first fixed baffle. When the central angles of the constituent sectors of the second fixed baffle are greater than those of the constituent sectors of the first fixed baffle, it indicates that the shape of the second fixed baffle is similar to that of the first fixed baffle. In this case, the second fixed baffle is partially exposed and forms a circle with the first fixed baffle. That is, the first fixed baffle partially blocks the second fixed baffle.

[0057] Taking the first fixed baffle as an example, which is funnel-shaped, the second fixed baffle is also funnel-shaped. The second fixed baffle is perpendicular to the first, and the two sector areas forming the second fixed baffle are greater than or equal to the two sector areas of the first fixed baffle. Therefore, when the first fixed baffle is superimposed on the second fixed baffle, a circle is formed. In normal mode, the first and second fixed baffles form a circle to protect the temperature sensor from accidental touches. In this case, the circle acts as a protective shell for the temperature sensor, preventing accidental touches from affecting the accuracy of the temperature detection results.

[0058] like Figure 4 As shown, 21 indicates the first fixed baffle, and 22 indicates the second fixed baffle. The first fixed baffle and the second fixed baffle combine to form a circle. At this time, the rotation angle of the first fixed baffle is 90°, and the rotation angle of the second fixed baffle is 0°.

[0059] like Figure 5 As shown, 20 indicates a movable baffle assembly, which is disposed between the first fixed baffle and the second fixed baffle. When the rotation angle of the movable baffle assembly is the same as the rotation angle of the first fixed baffle, it is hidden under the first fixed baffle. Figure 4 As shown, only the first and second fixed baffles are displayed; when the rotation angle of the movable baffle assembly is the same as the rotation angle of the second fixed baffle, as... Figure 6 As shown, the movable baffle assembly covers the second fixed baffle for demonstration purposes. This indicates that the electromagnetic shield has a multi-layered structure, and the shielding mode is switched by rotating the movable baffle assembly.

[0060] In one embodiment, the first fixed baffle is provided with a plurality of first vent holes, and the second fixed baffle is provided with a plurality of second vent holes, wherein the first vent holes and the second vent holes have different shapes.

[0061] Specifically, the shapes and diameters of the multiple first vent holes on the first fixed baffle and the second vent holes on the second fixed baffle are different. For example, the shapes of the first vent holes are circular, rectangular, or rhomboid, while the shapes of the second vent holes are strip-shaped, elliptical, or fan-shaped. Figure 4 As shown, in this embodiment, the first vent is circular and the second vent is strip-shaped. Since the first vent will not be covered or blocked, while the movable baffle assembly will block the second vent, the diameter of the first vent is smaller than that of the second vent to ensure the shielding effect of the electromagnetic shield on electromagnetic signals.

[0062] In one embodiment, when the rotation angle of the movable baffle is the same as the rotation angle of the second fixed baffle, each vent hole on the movable baffle is aligned with the vent hole at the corresponding position on the second fixed baffle.

[0063] Specifically, the position of the vent hole on each movable baffle is aligned with the position of the vent hole on the second fixed baffle, which ensures airflow and prevents inaccurate temperature sensor detection due to poor airflow.

[0064] In one embodiment, the surface of the electromagnetic shield is covered with an electromagnetic shielding material.

[0065] Specifically, the surface of the electromagnetic shield is covered with electromagnetic shielding material, that is, each baffle of the electromagnetic shield is covered with electromagnetic shielding material. The electromagnetic shielding material can be metal fiber shielding material, conductive rubber shielding material, filled composite shielding material, etc. The number of filter layers of the electromagnetic shield can be changed by adjusting the rotation angle of the movable baffle. The more movable baffles covering the second fixed baffle, that is, the thicker the overlapping electromagnetic shielding material, the better the shielding effect. In addition, the rotation structure of the movable baffle can save space.

[0066] In one embodiment, the refrigerator compartment further includes a fan with fan blades facing the temperature sensor, the temperature sensor being located between the fan and the electromagnetic shield.

[0067] Specifically, refer to Figure 9 The 4-point indicator fan is located on the back side of the temperature sensor, that is, the temperature sensor is located between the fan and the electromagnetic shield. The fan draws air into the electromagnetic shield to prevent the airflow from being blocked due to the small diameter of the vent holes on the baffle of the electromagnetic shield, which would lead to inaccurate temperature detection.

[0068] In one embodiment, Figure 10 This is a flowchart illustrating a refrigerator control method in one embodiment, with reference to... Figure 10 A refrigerator control method is provided. This embodiment mainly applies this method to the above-mentioned... Figure 1 Taking a refrigerator control device as an example, the refrigerator control method specifically includes the following steps:

[0069] Step S210: When the refrigerator door status is detected to switch from open to closed, the negative ion generator in the refrigerator is started, and the target sterilization mode of the negative ion generator is determined according to the continuous opening time when the door is open, and the negative ion generator is controlled to operate according to the target sterilization mode.

[0070] Specifically, when the refrigerator door is open, it means the user has opened the refrigerator door; when the refrigerator door is closed, it means the user has closed the refrigerator door. During the open state, the bacterial content inside the refrigerator increases. Therefore, when switching from open to closed, the negative ion generator needs to be activated for sterilization. The sterilization power of the negative ion generator varies depending on the sterilization mode. The target sterilization mode needs to be determined based on the duration the door is open. A longer open door time results in a greater increase in bacteria inside the refrigerator, thus requiring a stronger sterilization mode. Conversely, a shorter open door time results in a smaller increase in bacteria inside the refrigerator, eliminating the need for a stronger sterilization mode; a weaker sterilization mode is sufficient.

[0071] Step S220: Determine the target shielding mode of the electromagnetic shielding device in the refrigerator according to the target sterilization mode, and control the operation of the electromagnetic shielding device according to the target shielding mode. The electromagnetic shielding device is located on the outer surface of the temperature sensor in the refrigerator and is used to shield the electromagnetic signal emitted by the negative ion generator to the temperature sensor.

[0072] Specifically, during the sterilization process according to the target sterilization mode, the negative ion generator emits electromagnetic signals to the temperature sensor. To avoid interference with the temperature sensor's detection results, an electromagnetic shield needs to be activated. This electromagnetic shield is located on the outer surface of the temperature sensor within the refrigerator and is used to shield the electromagnetic signals emitted by the negative ion generator. The intensity of the electromagnetic signals emitted by the negative ion generator varies depending on the sterilization mode. To prevent the negative ion generator from emitting electromagnetic signals to the temperature sensor during sterilization, the target shielding mode of the electromagnetic shield needs to be determined based on the target sterilization mode. The electromagnetic shield is then controlled to operate according to the target shielding mode, thereby shielding the electromagnetic signals emitted by the negative ion generator to the temperature sensor during the target sterilization mode. This reduces the influence of the signals emitted by the negative ion generator on the temperature sensor's detection, ensuring the accuracy of the temperature sensor's detection and preventing low accuracy from affecting the refrigerator's normal cooling effect, thus contributing to food preservation.

[0073] In one embodiment, the target sterilization mode of the negative ion generator is determined based on the duration of continuous door opening when the door is in an open state, including at least one of the following:

[0074] When the continuous opening time of the cabinet door is within a first time range, the first sterilization mode corresponding to the first time range is determined as the target sterilization mode of the negative ion generator. The first sterilization mode includes a first sterilization voltage, which is the output voltage that controls the output of the negative ion generator.

[0075] When the door is in the open state and the continuous opening time is within the second time range, the second sterilization mode corresponding to the second time range is determined as the target sterilization mode of the negative ion generator. The minimum time value in the second time range is greater than the maximum time value in the first time range. The second sterilization mode includes a second sterilization voltage, which is greater than the first sterilization voltage.

[0076] When the door is in the open state and the continuous opening time is within the third time range, the third sterilization mode corresponding to the third time range is determined as the target sterilization mode of the negative ion generator. The minimum time value in the third time range is greater than the maximum time value in the second time range. The third sterilization mode includes a third sterilization voltage, which is greater than the second sterilization voltage.

[0077] Specifically, the maximum duration within the first time range is less than the minimum duration within the second time range, and the maximum duration within the second time range is less than the minimum duration within the third time range. The continuous door-opening duration is denoted as t0. When the continuous door-opening duration falls within the first time range, it indicates that the user quickly closed the door after opening it, meaning the door opening time is short. Therefore, the first sterilization mode corresponding to the first time range has the weakest sterilization effect but lower energy consumption. The first time range can specifically be (0,0.5), (0,1), (0,1.5), etc., in minutes (min). In this embodiment, the first time range is set to (0,1), and the continuous door-opening duration is less than 1 minute, i.e., t0 < 1 min.

[0078] When the door is open and the duration of continuous opening falls within the second time range, the second sterilization mode corresponding to the second time range is selected as the target sterilization mode. The sterilization intensity of the second sterilization mode is greater than that of the first sterilization mode. The second time range can be (2,3), (2,5), (3,5), etc., with the unit being minutes (min). In this embodiment, the second time range is set to (2,5), that is, when the continuous opening time t0 = 2min to 5min, the second sterilization mode is selected as the target sterilization mode.

[0079] When the continuous opening time of the refrigerator door falls within the third time range, it indicates that the user has been keeping the refrigerator door open for a relatively long period. This scenario significantly increases the bacterial content inside the refrigerator compartment. Therefore, the third sterilization mode with the strongest sterilization power is required as the target sterilization mode. That is, the sterilization power of the third sterilization mode is greater than that of the second sterilization mode. The third time range can specifically be greater than 5 minutes, greater than 6 minutes, greater than 10 minutes, etc. In this embodiment, the third time range is set to greater than 5 minutes, that is, when the continuous opening time t0 > 5 minutes, the third sterilization mode is selected as the target sterilization mode.

[0080] In one embodiment, determining the target shielding mode of the electromagnetic shielding device in the refrigerator according to the target sterilization mode includes at least one of the following:

[0081] When the target sterilization voltage in the target sterilization mode is the first sterilization voltage, the first shielding mode corresponding to the first sterilization voltage is taken as the target shielding mode of the electromagnetic shield, wherein the sterilization voltage is the output voltage of the negative ion generator;

[0082] When the target sterilization voltage in the target sterilization mode is the second sterilization voltage, the second shielding mode corresponding to the second sterilization voltage is taken as the target shielding mode of the electromagnetic shield, wherein the shielding strength of the second shielding mode is greater than the shielding strength of the first shielding mode, and the second sterilization voltage is greater than the first sterilization voltage.

[0083] When the target sterilization voltage in the target sterilization mode is the third sterilization voltage, the third shielding mode corresponding to the third sterilization voltage is taken as the target shielding mode of the electromagnetic shield, wherein the shielding strength of the third shielding mode is greater than the shielding strength of the second shielding mode, and the third sterilization voltage is greater than the second sterilization voltage.

[0084] Specifically, the sterilization voltage varies depending on the sterilization mode. Sterilization voltage refers to the output voltage controlling the negative ion generator. The first sterilization mode includes a first sterilization voltage, the second sterilization mode includes a second sterilization voltage, and the third sterilization mode includes a third sterilization voltage. The third sterilization voltage is greater than the second sterilization voltage, and the second sterilization voltage is greater than the first sterilization voltage. Therefore, the higher the sterilization voltage, the stronger the sterilization effect. The first, second, and third sterilization voltages can be customized in ascending order of voltage value. In this embodiment, the first sterilization voltage is set to V. a The value range is 2.5kV to 3.5kV, let the second sterilization voltage V b The value range is 3.5kV to 5.0kV, and the third sterilization voltage V c The value range is 5.0kV to 7.5kV.

[0085] Reference Figure 7 and Figure 8 When the target sterilization mode is the first sterilization mode, the negative ion generator operating according to the target sterilization mode will output the first sterilization voltage. That is, when the output voltage of the negative ion generator is 2.5kV to 3.5kV, the first shielding mode is determined as the target shielding mode of the electromagnetic shield. In the first shielding mode, the electromagnetic shield rotates the first movable baffle out from behind the first fixed baffle and covers the outer surface of the second fixed baffle. The first movable baffle has multiple grid-like ventilation holes. The multi-layered, porous structure of the electromagnetic shield can shield the electromagnetic signals emitted by the negative ion generator, and the surface of each baffle in the electromagnetic shield is covered with electromagnetic shielding material, which can also play a signal shielding role.

[0086] When the target sterilization mode is the second sterilization mode, the negative ion generator operating according to the target sterilization mode will output a second sterilization voltage. That is, when the output voltage of the negative ion generator is 3.5kV to 5.0kV, the second shielding mode is determined as the target shielding mode of the electromagnetic shield. In the second shielding mode, the electromagnetic shield rotates the second movable baffle out from behind the first fixed baffle and covers the outer surface of the first movable baffle. The second movable baffle has multiple circular ventilation holes. Before the second movable baffle covers the first movable baffle, the diameter of the ventilation holes becomes smaller, and the flow orifice changes from a grid shape to a circular shape. Furthermore, the second movable baffle and the first movable baffle overlap, resulting in an additional layer of shielding material, which enhances the signal shielding effect.

[0087] When the target sterilization mode is the third sterilization mode, the negative ion generator operating according to the target sterilization mode will output the third sterilization voltage. That is, when the output voltage of the negative ion generator is 5.0kV to 7.5kV, the third shielding mode is determined as the target shielding mode of the electromagnetic shield. In the third shielding mode, the electromagnetic shield rotates the third movable baffle out from behind the first fixed baffle and covers the outer surface of the second movable baffle. The third movable baffle has multiple circular ventilation holes. The diameter of the circular ventilation holes on the third movable baffle is smaller than that on the second movable baffle. Before the third movable baffle covers the second movable baffle, the diameter of the ventilation holes becomes smaller, and the flow orifice changes from a large circular hole to a small circular hole. Furthermore, the third movable baffle, the second movable baffle, and the first movable baffle are stacked in sequence, so that the shielding material covers an additional layer, further enhancing the signal shielding effect. Furthermore, in the third shielding mode, the fan located after the temperature sensor draws airflow through the vent into the electromagnetic shield to prevent the airflow from being too small, which would lead to inaccurate temperature detection.

[0088] In different shielding modes, the electromagnetic shield adjusts the size of the flow orifice by adjusting the movable baffles to shield the magnetic field signal. The higher the output voltage of the negative ion generator, the stronger the electromagnetic signal; the smaller the adjustable orifice of the shield, the stronger the shielding effect. Specifically, the orifices of the first fixed baffle, the first movable baffle, the second movable baffle, and the third movable baffle decrease sequentially. During operation, the rotation angle is fixed, and they cover each other from largest to smallest, with the smaller orifice covering the outer surface of the larger orifice. After covering, the orifices remain hole-to-hole, ensuring airflow under the action of the fan. This rotating overlapping method saves space, and because of the overlapping shielding material, the thicker the shielding material, the better the shielding effect.

[0089] When the negative ion generator is turned off, the electromagnetic shield is in the default shielding mode. In the default shielding mode, all the movable baffles are hidden behind the first fixed baffle, that is, only the first fixed baffle and the second fixed baffle are visible. At this time, the electromagnetic shield acts as a protective shell for the temperature sensor to prevent users from accidentally touching the temperature sensor when taking food out of the refrigerator, which could cause the temperature sensor to fall off or malfunction.

[0090] In one embodiment, when the target sterilization voltage in the target sterilization mode is a third sterilization voltage, after taking the third shielding mode corresponding to the third sterilization voltage as the target shielding mode of the electromagnetic shield, the method further includes:

[0091] Obtain the temperature of the cold storage compartment;

[0092] When the difference between the detected temperature and the set temperature in the refrigerator compartment is greater than or equal to the preset temperature difference, the compressor and fan in the refrigerator are started, and the refrigerator compartment air damper is opened. When the difference between the detected temperature and the set temperature in the refrigerator compartment is less than the preset temperature difference, the compressor and the fan are turned off, and the refrigerator compartment air damper is closed.

[0093] Determine whether the on-time of the negative ion generator is greater than or equal to the third shielding time in the third shielding mode;

[0094] If the activation duration of the negative ion generator is greater than or equal to the third shielding duration, the target shielding mode of the electromagnetic shielding device is switched from the third shielding mode to the fourth shielding mode, and the electromagnetic shielding device is controlled to operate according to the target shielding mode. The shielding strength of the fourth shielding mode is the same as that of the second shielding mode, the fourth shielding duration in the fourth shielding mode is less than the second shielding duration in the second shielding mode, and the fourth shielding duration is greater than the third shielding duration.

[0095] Specifically, after the electromagnetic shield operates according to the third sterilization mode, the temperature sensor detects the refrigerator compartment temperature in real time. That is, the temperature sensor obtains the detected temperature of the refrigerator compartment and sets the temperature as the target temperature for cooling in the refrigerator compartment. The preset temperature difference can be customized according to the actual application scenario. In this embodiment, the preset temperature difference T is set to a range of 2℃ to 3℃. When the difference between the detected temperature of the refrigerator compartment and the set temperature is less than the preset temperature difference, it means that the detected temperature of the refrigerator compartment is close to the set temperature, and there is no need to cool the refrigerator compartment. When the difference between the detected temperature of the refrigerator compartment and the set temperature is greater than or equal to the preset temperature difference, it means that the detected temperature of the refrigerator compartment is significantly different from the set temperature. It is necessary to start the compressor and fan in the refrigerator compartment to cool the refrigerator compartment and open the refrigerator compartment damper to cool the refrigerator compartment until the detected temperature of the refrigerator compartment gradually approaches the set temperature, that is, the difference between the detected temperature of the refrigerator compartment and the set temperature is less than the preset temperature difference. Then, the compressor and fan are controlled to stop working and the refrigerator compartment damper is closed.

[0096] After stopping the compressor and fan and closing the refrigerator compartment damper, it is determined whether the operating duration of the negative ion generator is greater than or equal to the third shielding duration in the third shielding mode. The operating duration of the negative ion generator indicates the time period from the start-up time of the negative ion generator to the current time. The operating duration of the negative ion generator can be understood as the working time after the negative ion generator is turned on, denoted as t1. The shielding mode includes a shielding duration, which indicates the working time after the control electromagnetic shielder is turned on. That is, the first shielding mode includes the first shielding duration, the second shielding mode includes the second shielding duration, and the third shielding mode includes the third shielding duration. The first, second, and third shielding durations can be the same or different, and can be customized according to the application scenario. For example, let the first shielding duration be greater than the second shielding duration, and the second shielding duration be greater than the third shielding duration. Assume the first shielding duration is t. a The value range is 8h to 10h, and the second shielding duration t b The value range is 7h to 8h, and the third shielding duration t c (The value range is 1h to 2h; or, let the first shielding duration be equal to the second shielding duration, and the first shielding duration be greater than the third shielding duration, for example, the first shielding duration t) a The value range is 8h to 10h, and the second shielding duration t b The value range is 8h to 10h, and the third shielding duration t c The value range is 1h to 2h.

[0097] In this embodiment, the first shielding duration is equal to the second shielding duration, and the first shielding duration is greater than the third shielding duration. The first shielding duration t a The value range is 8h to 10h, and the second shielding duration t bThe value range is 8h to 10h, and the value range of the third shielding duration is 1h to 2h. The condition is that the duration of the negative ion generator's operation is greater than or equal to the third shielding duration, i.e., t1 ≥ t. c If this condition is met, it means that the working time of the negative ion generator exceeds the working time of the electromagnetic shield. To prevent the electromagnetic shield from interfering with the temperature sensor due to the electromagnetic signal emitted by the negative ion generator while the negative ion generator is still working, the working time of the electromagnetic shield needs to be extended. Therefore, the target shielding mode is switched from the third shielding mode to the fourth shielding mode. The shielding structure of the electromagnetic shield in the fourth shielding mode is the same as that in the second shielding mode, in which the second movable baffle is rotated out from behind the first fixed baffle and covers the outer surface of the first movable baffle. However, the fourth shielding time t in the fourth shielding mode is different. d The fourth shielding duration is greater than the third shielding duration but less than the second shielding duration. In this embodiment, the fourth shielding duration is set to a range of 7h to 8h. The electromagnetic shielding device continues to operate according to the target shielding mode to extend the operating time of the electromagnetic shielding mode.

[0098] In one embodiment, after controlling the electromagnetic shield to operate according to the target shielding mode, the method further includes:

[0099] Obtain the temperature of the cold storage compartment;

[0100] When the difference between the detected temperature and the set temperature in the refrigerator compartment is greater than or equal to the preset temperature difference, the compressor and fan in the refrigerator are started, and the refrigerator compartment damper is opened.

[0101] When the difference between the detected temperature and the set temperature in the refrigerator compartment is less than the preset temperature difference, the compressor and the fan are controlled to stop, and the refrigerator compartment damper is closed.

[0102] Specifically, when the target shielding mode is the first shielding mode or the second shielding mode, after controlling the electromagnetic shielding device to operate according to the target shielding mode, it is necessary to determine whether the refrigerator compartment needs to be cooled down based on the comparison between the difference between the detected temperature of the refrigerator compartment and the set temperature and the preset temperature difference collected by the temperature sensor. If the difference between the detected temperature of the refrigerator compartment and the set temperature is greater than or equal to the preset temperature difference, then the refrigerator compartment needs to be cooled down. Therefore, the compressor and fan are started, and the refrigerator compartment damper is opened to cool down the refrigerator compartment. Until the difference between the detected temperature of the refrigerator compartment and the set temperature is less than the preset temperature difference, then there is no need to cool down the refrigerator compartment. Then the compressor and fan are stopped, and the refrigerator compartment damper is closed.

[0103] In one embodiment, after controlling the compressor and the fan to stop and closing the refrigerator compartment damper when the difference between the detected temperature and the set temperature in the refrigerator compartment is less than a preset temperature difference, the method further includes:

[0104] Determine whether the activation duration of the negative ion generator is greater than or equal to the shielding duration corresponding to the target shielding mode;

[0105] If the on-time of the negative ion generator is greater than or equal to the off-time corresponding to the target shielding mode, then the negative ion generator is turned off, and the electromagnetic shield is controlled to operate according to the first shielding mode; or,

[0106] If the activation duration of the negative ion generator is less than the shielding duration corresponding to the target shielding mode, then return to the step of obtaining the temperature of the refrigerator compartment.

[0107] Specifically, when the difference between the detected temperature and the set temperature in the refrigerator compartment is less than a preset temperature difference, the compressor and the fan are stopped, and the refrigerator compartment damper is closed. Then, it is determined whether the on-time of the negative ion generator is greater than or equal to the off-time corresponding to the target shielding mode. If the target shielding mode is either the first or second shielding mode, and the first and second shielding times are the same, the off-time corresponding to the target shielding mode is the first shielding time in the first shielding mode. If the first shielding time is not equal to the second shielding time, the off-time corresponding to the target shielding mode being the first shielding mode is the first shielding time, and the off-time corresponding to the target shielding mode being the second shielding mode is the second shielding time. The off-time corresponding to the target shielding mode being the third shielding mode is the sum of the third and fourth shielding times, i.e., t. c +t d .

[0108] When the on-time of the negative ion generator is greater than or equal to the off-time corresponding to the target shielding mode, it indicates that the negative ion generator has been on for a long time. In this case, the negative ion generator is turned off and the electromagnetic shield is switched to the default shielding mode, which hides all the movable baffles behind the first fixed baffle. At this time, the electromagnetic shield acts as a protective shell for the temperature sensor. The temperature sensor collects the temperature difference between the detected temperature and the set temperature in the refrigerator compartment in real time to keep the temperature inside the refrigerator compartment stable.

[0109] If the on-time of the negative ion generator is less than the off-time corresponding to the target shielding mode, the process will return to the previous steps of obtaining the temperature of the refrigerator compartment and controlling the operation of the compressor and fan. At this time, there is no need to turn off the negative ion generator. The negative ion generator and the electromagnetic shielding device will continue to work. It is only necessary to ensure that the temperature inside the refrigerator compartment is stable.

[0110] In one embodiment, if the on-time of the negative ion generator is greater than or equal to the off-time corresponding to the target shielding mode, then after turning off the negative ion generator and controlling the electromagnetic shield to operate according to the first shielding mode, the method further includes:

[0111] When the door status is not detected to switch from closed to open, the negative ion generator is started at preset intervals, and the negative ion generator is controlled to operate in the first sterilization mode, and the electromagnetic shield is controlled to operate in the first shielding mode.

[0112] Specifically, if the door status is not detected to switch from closed to open, the negative ion generator will be activated at a preset interval before the user opens the refrigerator door again. The preset interval can be customized according to the actual application scenario, such as 8 hours, 16 hours, 24 hours, etc. The negative ion generator will periodically perform sterilization treatment on the inside of the refrigerator compartment according to the first sterilization mode, and the electromagnetic shielding mode will be controlled to shield the electromagnetic signals generated by the negative ion generator when it is running in the first sterilization mode, so as to prevent the electromagnetic signals from interfering with the temperature sensor.

[0113] In one specific embodiment, refer to Figure 7 , Figure 8 and Figure 11 The refrigerator control method specifically includes the following steps:

[0114] After the user opens the refrigerator door, the timer inside the refrigerator starts timing the duration t0 when the door is open, the negative ion generator starts timing the duration t1 when the negative ion generator is on.

[0115] When t0 < 1 min, control the output voltage of the negative ion generator to the first sterilization voltage V. a (V a (Voltage range: 2.5kV to 3.5kV), and simultaneously, the electromagnetic shielding device activates its first shielding mode, with a processing time of t. a (t a The processing time is 8-10 hours, which is the same as the shielding time. a This is the first blocking duration.

[0116] When t0 = 2 min to 5 min, control the output voltage of the negative ion generator to the second sterilization voltage V. b (V b (3.5kV~5.0kV), and simultaneously the electromagnetic shielding device activates its second shielding mode, with a processing time of t. b , t b This is the second shielding duration, where t is... b =t a .

[0117] When t0 > 5 min, control the output voltage of the negative ion generator to the third sterilization voltage V. c (V c (Voltage range: 5.0kV to 7.5kV), and simultaneously, the electromagnetic shielding device activates its third shielding mode, with a processing time of t. c (t c (1h~2h), t c For the third shielding duration, after the electromagnetic shielder operates in the third shielding mode, when the difference between the detected temperature and the set temperature in the refrigerator compartment is greater than or equal to the preset temperature difference, the compressor and fan are turned on, and the refrigerator compartment damper is opened to cool the refrigerator compartment until the difference between the detected temperature and the set temperature in the refrigerator compartment is less than the preset temperature difference. Then, the compressor, fan, and refrigerator compartment damper are turned off, and it is determined that t1≥t c If the condition is met, the electromagnetic shielding device is switched to the fourth shielding mode. The processing time is t. d (t d (7h~8h), t d This is the fourth shielding duration. Afterwards, the refrigerator compartment temperature is collected again. When the difference between the detected refrigerator compartment temperature and the set temperature is greater than or equal to the preset temperature difference, the compressor and fan are turned on, and the refrigerator compartment damper is closed. This continues until the difference between the detected refrigerator compartment temperature and the set temperature is less than the preset temperature difference, at which point the compressor, fan, and refrigerator compartment damper are turned off, and it is determined that t1 ≥ t c +t d If the condition is met, the negative ion generator will be turned off, and the electromagnetic shield will be switched to the default shielding mode. The temperature of the refrigerator compartment will be collected in real time by the temperature sensor to ensure that the temperature inside the refrigerator compartment is stable.

[0118] After the electromagnetic shielding device activates its first or second shielding mode, the temperature sensor continuously monitors the refrigerator compartment temperature. If the difference between the detected temperature and the set temperature is less than the preset temperature difference T (T is 2℃~3℃), no cooling of the refrigerator compartment is required. Otherwise, the compressor and fan start working, and the refrigerator compartment damper opens to cool the compartment. When the difference between the detected temperature and the set temperature is less than T, the compressor, fan, and temperature sensor stop working, and the refrigerator compartment damper closes. Then, it is determined that t1≥t a If the condition is met, the negative ion generator will be turned off, and the electromagnetic shield will be switched to the default shielding mode. The temperature of the refrigerator compartment will be collected in real time by the temperature sensor to ensure that the temperature inside the refrigerator compartment is stable.

[0119] After the negative ion generator is turned off, it will remain on for a set duration (t) every 24 hours until the user next opens the refrigerator door. a The preset interval is 24 hours, and it operates in the first sterilization mode every 24 hours, controlling the output voltage of the negative ion generator to the first sterilization voltage V. aAt the same time, the electromagnetic shielding device activates its first shielding mode.

[0121] In one embodiment, such as Figure 12 As shown, a refrigerator control device is provided, comprising:
