[0002] In family life, refrigerators have become an indispensable household appliance, and users often store large amounts of food inside them. However, the more food stored in the refrigerator, the easier it is for bacteria to grow inside, leading to food spoilage and even endangering the user's health.

[0003] Currently, some refrigerators are equipped with sterilization modules, but due to the wide variety of food stored inside and the complex environment of the refrigerator, the sterilization effect is poor. Summary of the Invention

[0012] As a further improvement to one embodiment of the present invention, the refrigerator control method further includes: Obtain the corresponding sterilization level based on the ingredient information; The sterilization speed corresponding to the fan and the sterilization operating frequency corresponding to the compressor are obtained according to the sterilization level. The higher the sterilization level, the higher the sterilization operating speed.

[0014] To achieve one of the above-mentioned objectives, one embodiment of the present invention provides a computer-readable storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the steps in the refrigerator control method of any of the above embodiments.

[0015] To achieve one of the above-mentioned objectives, one embodiment of the present invention provides a refrigerator, including a refrigerator compartment and a freezer compartment.

Attached Figure Description

[0017] Figure 1 This is a schematic diagram of a refrigerator according to one embodiment of the present invention; Figure 2 This is a flowchart of a refrigerator control method according to an embodiment of the present invention; Figure 3 This is a detailed flowchart of a refrigerator control method according to an embodiment of the present invention; Figure 4 This is a schematic diagram of the various modules inside a refrigerator according to one embodiment of the present invention. Specific Implementation To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0019] See Figure 1A refrigerator 100 provided in one embodiment of the present invention includes a refrigerator compartment 110 and a freezer compartment 120. Both the refrigerator compartment 110 and the freezer compartment 120 of the refrigerator 100 can be equipped with a sterilization module, which can be an ozone sterilization module. By operating the sterilization module, sterilization and deodorization can be performed in the refrigerator compartment 110 and the freezer compartment 120, reducing bacterial growth. The refrigerator 100 may also include a refrigeration system, which may include a compressor, a condenser, and an evaporator connected in sequence. Air ducts may also be provided in the refrigerator compartment 110 and the freezer compartment 120, and the evaporator can be installed in the air ducts. A fan may also be installed in the air ducts, and the operation of the fan can further promote cold air circulation. The refrigerator 100 may be equipped with a communication module, which can communicate with mobile devices such as mobile phones to send relevant information about the refrigerator 100 to the mobile devices for user viewing and management.

[0020] The refrigerator 100 can operate in two modes: normal mode and smart freeze mode. In normal mode, the compressor operates at a normal operating frequency according to a preset cycle, and the fan operates at a preset normal speed to cool the refrigerator compartment 110 or the freezer compartment 120. When food is detected inside the refrigerator 100, the refrigerator 100 can be switched to smart freeze mode.

[0021] See Figure 2 An embodiment of the present invention provides a control method that can be used in the refrigerator 100 described above, comprising: Check if food is stored inside the refrigerator; If so, control the sterilization module and fan to operate in sterilization mode; Determine whether the environmental parameters inside the refrigerator 100 meet the normal storage parameters; If so, the sterilization module is controlled to operate in normal mode and the fan is controlled to shut down, wherein the sterilization intensity of the sterilization module when operating in sterilization mode is greater than the sterilization intensity when operating in normal mode.

[0022] In this embodiment, when food is detected being placed inside the refrigerator 100, the refrigerator 100's operating mode can automatically switch to smart freezing mode. When the environmental parameters inside the refrigerator 100 meet the normal storage parameters, the refrigerator 100's operating mode can automatically switch to normal mode. In normal mode, the sterilization module can operate at preset time intervals to sterilize and deodorize the refrigerator 100.

[0023] In Smart Freeze mode, the sterilization module and fan can be controlled to operate in sterilization mode. In this mode, the sterilization intensity of the sterilization module is greater than that in normal mode, and the fan speed is higher than the normal speed of the fan in normal mode. In Smart Freeze mode, the sterilization module and fan can continue to operate until switching back to normal mode.

[0024] Thus, when a user puts food into the refrigerator 100, the fan operates in sterilization mode, which can quickly cool the food inside the refrigerator 100, accelerate the air-cooling circulation inside the refrigerator 100, and increase the sterilization intensity of the sterilization module. This reduces the possibility of bacterial growth in newly added food, achieving a better sterilization and deodorization effect. When the environmental parameters inside the refrigerator 100 meet the normal storage parameters, the fan can be turned off and controlled to operate according to a preset normal mode. For example, the fan can rotate at a preset normal speed when each cooling cycle is started, and the sterilization module can also operate in normal mode at preset time intervals, thereby saving energy consumption.

[0025] Furthermore, in one embodiment of the present invention, "detecting whether food has been placed inside the refrigerator 100" includes: Detect the temperature information inside the refrigerator 100; Determine whether the temperature rise within the preset time period is greater than the preset value.

[0026] In this embodiment, temperature sensors can be installed in the refrigerator compartment 110 and / or freezer compartment 120 of the refrigerator 100. These temperature sensors can detect the temperature information inside the refrigerator 100 in real time. The refrigerator 100 may also include a refrigerator door for opening and closing the refrigerator compartment 110 and a freezer door for opening and closing the freezer compartment 120. Door status detection modules can be installed on the refrigerator and freezer doors, and these modules can be Hall effect sensors or pressure sensors. The door status detection modules can detect the opening and closing status of the refrigerator and freezer doors. When the opening and closing status of the refrigerator and freezer doors changes, the temperature sensors can be controlled to detect the temperature information of the corresponding compartment. When the temperature detected after the refrigerator door is closed is greater than the preset temperature value before the refrigerator door is opened, it can be determined that food was placed into the refrigerator 100 by the user during the opening period.

[0027] The preset values ​​for the refrigerator compartment 110 and the freezer compartment 120 can be different. For example, it can be determined that food has been put into the refrigerator compartment 110 when the temperature of the refrigerator compartment 110 rises by more than 3°C, and that food has been put into the freezer compartment 120 when the temperature of the freezer compartment 120 rises by more than 5°C.

[0028] In this way, it is possible to directly determine whether the user needs to add food based on temperature changes, without the need to install other components.

[0029] Further, see Figure 3 In one embodiment of the present invention, "determining whether the environmental parameters inside the refrigerator 100 meet the normal storage parameters" includes: Detect the temperature information inside the refrigerator 100; Determine if the temperature is lower than the preset temperature.

[0030] In this embodiment, when the temperature of the refrigerator compartment 110 or the freezer compartment 120 is detected to be lower than the preset temperature, it can be determined that the environmental parameters inside the refrigerator 100 meet the normal storage parameters. At this time, the refrigerator 100 can be switched to normal mode to avoid energy waste.

[0031] Of course, you can also directly determine whether the environmental parameters inside the refrigerator 100 meet the normal storage parameters based on the activation time of the smart freeze mode. For example, if the fan runs at the sterilization speed for a preset time, it is determined that the environmental parameters inside the refrigerator 100 meet the normal storage parameters. The corresponding time may be different for different foods.

[0032] In another embodiment of the present invention, "determining whether the environmental parameters inside the refrigerator 100 meet the normal storage parameters" includes: Detect the temperature information of the food storage area; Determine whether the temperature of the storage area is lower than the preset temperature.

[0033] In this embodiment, the refrigerator compartment 110 and freezer compartment 120 of the refrigerator 100 can be equipped with multiple shelves. Users can place food on the shelves, and the storage area corresponding to the shelf where the food is placed is the food storage area. Temperature sensors can be installed in the storage space corresponding to each shelf, allowing for more accurate monitoring of the environment inside the refrigerator 100. The storage area for placed food can also be determined based on the temperature information detected by the temperature sensors. The fan can be a shielding fan, including multiple vents corresponding to each shelf, thereby controlling the shielding fan to open the corresponding vents and precisely deliver cold air to the storage area corresponding to the food. Alternatively, the location of the food can be determined directly through other recognition devices such as cameras, and the shielding fan can be precisely controlled to achieve better sterilization and deodorization effects.

[0034] When the temperature in the food storage area is lower than the preset temperature, it can be determined that the environmental parameters inside the refrigerator 100 have reached the normal storage parameters, and the operating mode of the refrigerator 100 can be switched to the normal mode.

[0035] Furthermore, in one embodiment of the present invention, the refrigerator 100 control method further includes: If food is detected inside the refrigerator 100, the food information is obtained. The corresponding sterilization speed of the blower is obtained based on the information of the ingredients, and the blower is controlled to run at the sterilization speed.

[0036] In this embodiment, the sterilization speed of the fan can be the speed at which the fan operates in sterilization mode. A camera can be installed inside the refrigerator 100 to capture images of the food stored inside the refrigerator 100 and upload the images to the cloud to obtain food information such as food names based on the characteristics of the food in the images.

[0037] The refrigerator 100 can be equipped with a storage module that can store information about the food ingredients and the corresponding sterilization speed. Of course, information such as the sterilization speed of the fan can also be stored in the cloud.

[0038] When the food placed in the refrigerator has a strong odor, the higher the sterilization speed of the fan, the better the sterilization and deodorization effect can be achieved for different types of food.

[0039] Furthermore, in one embodiment of the present invention, the refrigerator 100 control method further includes: Obtain the ingredient information and determine the corresponding sterilization frequency of the compressor based on the ingredient information; Control the compressor to operate at the sterilization frequency; When the environmental parameters inside the refrigerator 100 meet the normal storage parameters, the compressor is controlled to shut down; among them, the sterilization frequency is higher than the preset frequency during normal operation.

[0040] In this embodiment, when food is detected being placed inside the refrigerator 100, the operating frequency of the compressor can be increased, and the stronger the odor of the food, the higher the operating frequency of the compressor can be. This allows for rapid cooling of the food when it is placed inside, while simultaneously accelerating the air-cooling circulation within the refrigerator 100.

[0041] Furthermore, in one embodiment of the present invention, the refrigerator 100 control method further includes: Obtain the corresponding sterilization level based on the ingredient information; The sterilization speed of the fan and the sterilization frequency of the compressor are determined according to the sterilization level. The higher the sterilization level, the higher the sterilization speed and the sterilization frequency.

[0042] In this embodiment, the sterilization level can include three levels: Level 1, Level 2, and Level 3. Food ingredients can be categorized, with each category corresponding to a sterilization level. Each sterilization level has a pre-set sterilization speed for the fan and a corresponding sterilization frequency for the compressor. Thus, the food information can be the food category; when identifying food, only the category to which the food belongs can be determined, thereby simplifying the food identification process.

[0043] For example, food ingredients can be divided into three categories: beverages, fruits and vegetables, and cooked food and opened food. Beverages correspond to a sterilization level of Level 1, fruits and vegetables to Level 2, and cooked food and opened food to Level 3. Level 1 corresponds to the highest fan sterilization speed and compressor sterilization frequency, while Level 3 corresponds to the lowest. However, even at Level 3, the fan sterilization speed is higher than the fan speed in normal mode, and the compressor sterilization frequency is higher than the compressor's operating frequency in normal mode.

[0044] Furthermore, in one embodiment of the present invention, the sterilization module includes an ozone sterilization module.

[0045] "Controlling the sterilization module to operate in sterilization mode" includes: After controlling the sterilization module to heat for a first preset time, the sterilization step is executed cyclically a first preset number of times. "Controlling the sterilization module to operate in normal mode" includes: After the sterilization module operates in heating mode for a first preset time, it cyclically performs the sterilization step a second preset number of times, wherein the second preset number of times is less than the first preset number of times.

[0046] In this embodiment, the sterilization module is an ozone sterilization module, which may include electrodes and a heater. When the ozone sterilization module is started, the heater can be started first to heat for a preset time to activate the electrodes. After heating for the preset time, the sterilization module can be controlled to cycle through the sterilization steps.

[0047] In this embodiment, controlling the sterilization module to perform sterilization steps may include: After the sterilization module is turned off for a second preset time, the sterilization module is turned on to release ozone. After the third preset duration, the sterilization module stops releasing ozone and heats for the fourth preset duration.

[0048] For a specific example, when starting the ozone sterilization module, first control the heating of the ozone module for 3 minutes to activate the motor of the ozone sterilization module, and then control the ozone module to perform the sterilization steps. Controlling the ozone module to perform the sterilization steps may include turning off the ozone sterilization module, turning it on after 3 seconds and releasing ozone for sterilization, stopping the release of ozone after 30 seconds and running in heating mode for 30 seconds to maintain electrode activity.

[0049] In sterilization mode, the sterilization module can perform sterilization steps more times within one operating cycle than in normal mode, thus achieving a higher sterilization intensity. For the freezer compartment 120 and the refrigerator compartment 110, due to differences in storage environment, bacteria and odors are more likely to develop in the refrigerator compartment. Therefore, the number of sterilization steps performed by the sterilization module in the freezer compartment 120 and the sterilization module in the refrigerator compartment 110 in normal mode can differ. For example, when the sterilization module in the freezer compartment 120 operates in normal mode, it can perform sterilization steps 3 times per sterilization cycle, while the sterilization module in the refrigerator compartment 110 operates in normal mode, it can perform sterilization steps 5 times per sterilization cycle. However, in sterilization mode, both the sterilization modules in the freezer compartment 120 and the refrigerator compartment 110 can perform 7 sterilization steps each.

[0050] Of course, due to differences in storage environments, the number of sterilization steps performed by the sterilization module in the freezer compartment 120 and the sterilization module in the refrigerator compartment 110 during sterilization mode may differ. Furthermore, the number of sterilization steps performed by the sterilization module can be determined based on food information or sterilization level; stronger food odors and higher sterilization levels allow for more frequent sterilization steps. This further reduces energy consumption.

[0051] Furthermore, the refrigerator 100 can also be equipped with an indicator light. When food is detected inside the refrigerator 100 and the refrigerator 100 enters the smart freeze mode, the indicator light can be controlled to flash. When the environmental parameters inside the refrigerator 100 meet the normal storage parameters, the indicator light can be controlled to turn off. At the same time, a prompt message can be sent to a mobile terminal through the communication module.

[0052] In a specific example of this invention, a camera is installed in the refrigerator compartment 110 of the refrigerator 100. When the refrigerator door is detected to have opened and closed, the camera can be activated to capture information about the food inside the refrigerator compartment 110. The captured image is then compared with an image of the refrigerator before the door was opened to determine whether food has been placed inside. If food is detected to have been placed inside the refrigerator compartment 110, the sterilization module can be controlled to operate in sterilization mode. First, the sterilization module is activated to operate in heating mode for 3 minutes, and then the sterilization module is controlled to repeat the sterilization steps 7 times. Simultaneously, the category of the placed food can be determined. If the placed food is detected to be cooked food or opened food, its corresponding sterilization level is determined to be level three. Then, the corresponding fan sterilization speed and compressor sterilization operating frequency are obtained, and the operation of the fan and compressor is controlled accordingly.

[0053] It can also monitor the temperature inside the refrigerator compartment 110 or the running time of the fan. For example, when the temperature inside the refrigerator compartment 110 is less than 5°C, it can exit the smart freeze mode, control the fan and compressor to shut down, and control the sterilization module to switch to normal mode. In normal mode, the compressor, fan and sterilization module can be started at preset time intervals to run with preset normal parameters.

[0054] See Figure 4 One embodiment of the present invention also provides a refrigerator 100, including a memory 102 and a processor 101, which are communicatively connected via a communication bus 104. The memory 102 stores a computer program that can run on the processor 101. When the processor 101 executes the computer program, it implements the steps in the refrigerator control method described in the above embodiment. The refrigerator also includes a communication interface 103 connected to the communication bus 104 for communicating with other devices of the refrigerator 100.

[0055] One embodiment of the present invention also provides a computer-readable storage medium having a computer program stored thereon, wherein when the computer program is executed by a processor, it implements the steps in the refrigerator control method described above.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
