[0124] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0125] In order to remove odors from a refrigerator without affecting the storage of items inside, this invention provides a new refrigerator that can automatically filter the air in the storage compartment, thereby removing odors from the storage compartment.

[0126] Additionally, after removing odors, the humidity in the storage compartment can be adjusted to ensure the food meets the required humidity levels, allowing it to be stored fresh. For specific details, please refer to... Figure 1 , Figure 1 A schematic diagram of the structure of a refrigerator according to an embodiment of the present invention is shown;

[0127] like Figure 1 As shown, the refrigerator 10 may include:

[0128] Humidity detection device 101 is used to detect the humidity of the storage compartment of refrigerator 10;

[0129] Air detection device 102 is used to detect the air in the storage cavity;

[0130] The control device is used to receive detection data sent by the humidity detection device 101 and the air detection device 102, and generate a corresponding first control command based on the detection data.

[0131] A fresh air system is used to adjust the humidity of the storage cavity and / or filter the air in the storage cavity in response to a first control command.

[0132] In some feasible embodiments, the refrigerator 10 may be equipped with a humidity detection device 101 and an air detection device 102; wherein, the humidity detection device 101 can be used to detect the humidity of the storage cavity of the refrigerator 10; the air detection device 102 can be used to detect the air in the storage cavity to detect whether there is an odor in the storage cavity.

[0133] For example, the air detection device 102 can be an electrochemical sensor or an ultraviolet photoionization sensor, or other sensors capable of detecting the presence of odors in the air; wherein, the electrochemical sensor can measure oxidizing and reducing air, including ammonia, hydrogen sulfide, and methanethiol, etc. The ultraviolet photoionization sensor can be used to measure malodorous air.

[0134] The humidity detection device 101 and the air detection device 102 can be connected to the control device of the refrigerator 10 and send the detection data generated based on the detection process to the control device; wherein, the humidity detection device 101 can output the humidity value of the storage cavity to the control device, and the air detection device 102 can output information indicating whether there is an odor in the storage cavity to the control device.

[0135] After receiving the detection data sent by the humidity detection device 101 and the air detection device 102, the control device can control the fresh air system of the refrigerator 10 according to the detection data. Specifically, after receiving the detection data sent by the humidity detection device 101 and the air detection device 102, the control device can first identify and analyze the detection data sent by the humidity detection device 101 and the air detection device 102, and generate a corresponding first control command based on the identification and analysis results. The first control command is used to control the fresh air system to adjust the humidity of the storage cavity and / or filter the air in the storage cavity.

[0136] After generating the first control command, the control device can send the first control command to the fresh air system of the refrigerator 10. After receiving the first control command, the fresh air system can respond to the first control command and perform the corresponding operation. For example, when the first control command is to adjust the humidity of the storage cavity, the fresh air system can humidify or dehumidify the storage cavity. When the first control command is to filter the air in the storage cavity, the fresh air system can first extract the air from the storage cavity, then filter the air in the storage cavity, and then discharge it back into the storage cavity. This embodiment of the invention does not limit this.

[0137] As another example, when the first control command is to filter the air in the storage cavity, the fresh air system can simultaneously draw in the air from the storage cavity, filter the air in the storage cavity, and then discharge it from the refrigerator 10 to avoid polluting the environment; on the other hand, it can draw in the air outside the refrigerator 10, filter the drawn air, and then discharge it into the storage cavity. This embodiment of the invention does not limit this.

[0138] In one embodiment of the present invention, the fresh air system may include:

[0139] The filter device 103 is connected to a fresh air inlet pipe 104 and a fresh air outlet pipe 105; the filter device 103 is used to filter the air entering the storage cavity from the fresh air inlet pipe 104; the filter device 103 is also used to discharge the filtered air into the storage cavity through the fresh air outlet pipe 105.

[0140] A water storage device 106 is connected to a filter device 103; the water storage device 106 is used to store the water filtered out by the filter device 103.

[0141] Humidification pipe 107 is connected to water storage device 106; humidification pipe 107 is used to drain water evaporated from water storage device 106 into storage chamber.

[0142] In some feasible embodiments, the fresh air system may consist of a water storage device 106 for humidification, a humidification pipe 107, and a filter device 103 for filtration; wherein the filter device 103 may be connected to a fresh air intake pipe 104 and a fresh air outlet pipe 105, one end of the fresh air intake pipe 104 may be connected to the filter device 103, and the other end of the fresh air intake pipe 104 may be connected to a storage cavity; one end of the fresh air outlet pipe 105 may be connected to the filter device 103, and the other end of the fresh air outlet pipe 105 may be connected to a storage cavity.

[0143] The air that needs to be filtered in the storage cavity can enter the filter device 103 through the fresh air intake pipe 104 and be filtered by the filter device 103.

[0144] As an example, the air filtered by the filter device 103 can be discharged from the refrigerator 10 or discharged into the storage cavity through the fresh air outlet pipe 105.

[0145] As another example, the fresh air outlet duct 105 can discharge air filtered by the filter device 103 and entering the filter device from the fresh air inlet duct 104 into the storage cavity, or it can discharge air filtered by the filter device 103 and entering the filter device from outside the refrigerator 10 into the storage cavity. This embodiment of the invention does not limit this.

[0146] In some feasible embodiments, if the filter device 103 extracts and filters the air in the storage cavity and then discharges it back into the storage cavity, it can be called internal circulation; if the filter device 103 extracts and filters the air in the storage cavity and discharges it out of the refrigerator, and then extracts and filters the outside air and discharges it into the storage cavity, it can be called external circulation.

[0147] For internal circulation, since the air discharged into the storage cavity is not drawn from the outside, the temperature of the air is close to the temperature of the storage cavity, which will not cause the temperature of the storage cavity to rise and affect the storage of the items stored in the storage cavity.

[0148] When filtering air, the filter device 103 not only filters out odor-causing gas molecules, but may also filter out a certain amount of moisture in the air; this moisture, after settling, can flow from the filter device 103 into the water storage device 106 for storage. For example, activated carbon is provided between the filter device 103 and the water storage device 106 to filter the water entering the water storage device 106 from the filter device 103.

[0149] Filtering the air in the storage cavity may reduce the humidity of the air in the storage cavity, which is not conducive to the preservation of fruits and vegetables. To address this issue, when the humidity in the storage cavity is low, the fresh air system can be controlled to humidify the storage cavity. Specifically, the fresh air system can evaporate the water in the water storage device 106, and then discharge the air carrying water molecules into the storage cavity through the humidification pipe 107 to humidify the storage cavity.

[0150] In one embodiment of the present invention, the fresh air intake pipe 104 is provided with a first valve, the fresh air outlet pipe 105 is provided with a second valve, and the humidification pipe 107 is provided with a third valve; when it is necessary to remove odors from the storage cavity, the first valve and the second valve can be opened; when it is necessary to humidify the storage cavity, the third valve can be opened. The present invention does not limit this.

[0151] In one embodiment of the present invention, the refrigerator 10 may further include:

[0152] Evaporator 108 is arranged adjacent to fresh air outlet pipe 105. Evaporator 108 is used to cool the air in fresh air outlet pipe 105.

[0153] In some feasible embodiments, the refrigerator 10 may also include an evaporator 108, which may be arranged adjacent to the fresh air outlet 105. Whether it is internal circulation or external circulation, the evaporator 108 can cool the air discharged from the fresh air outlet 105 into the storage cavity, thereby avoiding the air discharged from the fresh air outlet 105 from affecting the temperature of the storage cavity.

[0154] In one embodiment of the present invention, the storage cavity may include at least a first sub-storage cavity and a second sub-storage cavity;

[0161] In one embodiment of the present invention, the filtration device 103 includes a first disinfection unit for disinfecting the filter element in the filtration device 103.

[0162] In some feasible embodiments, to prevent the filter device 103 from breeding bacteria, a first disinfection unit can be provided in the filter device 103 so that the filter element of the filter device 103 can be disinfected after the filter device 103 has been running for a period of time. The filter element of the filter device 103 can be used to filter the air entering the filter device 103 from the fresh air intake pipe 104.

[0163] For the filter element of the filter device 103, the filter element in the filter device 103 is provided with a first self-testing device, which is used to detect the usage level of the filter element in the filter device 103.

[0166] For example, the first disinfection unit may be a sterilization device such as an ultraviolet germicidal lamp.

[0167] In another embodiment of the present invention, a filter element is provided in the water storage device 106, and the filter element of the water storage device 106 is used to filter the water supplied to the humidification pipe 107.

[0168] In some feasible embodiments, in order to avoid the release of germs and odor molecules into the storage cavity when humidifying the storage cavity, a filter element can be provided in the water storage device 106; the filter element can be placed between the water storage device 106 and the humidification pipe 107 to filter the water supplied by the water storage device 106 to the humidification pipe 107.

This second self-testing device can be used to detect the degree of use of the filter element in the water storage device 106. For example, the degree of use can be expressed as a health status as a percentage, initially 100%, and gradually decreasing according to the degree of use.

[0174] After determining the usage level of the filter element in the water storage device 106, the refrigerator 10 can display it; for example, it can be displayed directly on the display panel of the refrigerator 10, or the information can be sent to the user's mobile terminal for display, and the embodiments of the present invention do not limit this.

[0175] In one embodiment of the present invention, a first fan may be provided in the filter device 103, which is used to move the air in the fresh air system.

[0176] In some feasible embodiments, a first fan can be provided in the filter device 103 to provide power to the air in the fresh air inlet pipe 104, the fresh air outlet pipe 105 and the filter device 103, so that the air in the storage cavity can enter the filter device 103 from the fresh air inlet pipe 104 for filtration, or the air entering the fresh air outlet pipe 105 from the filter device 103 can enter the storage cavity.

[0177] In another embodiment of the present invention, in order to improve the humidification efficiency, the refrigerator 10 may further include, for the purpose of humidification:

[0178] The second fan is used to move the water evaporated from the water storage device 106 to the humidification pipe 107.

[0179] In some feasible embodiments, a second fan can also be provided between the water storage device 106 or the humidification pipe 107. The second fan can provide power for the water evaporated from the water storage device 106, so that the water evaporated from the water storage device 106 can enter the humidification pipe 107 and enter the storage cavity through the humidification pipe 107.

[0180] like Figure 2a As shown, the filter device 103 is equipped with a filter element 109 and a first fan 110; a water pipe is provided at the bottom of the filter device 103 and connected to the water storage device 107 to transfer the water removed from the filter device 103 to the water storage device 106.

The water storage box 113 is equipped with a filter element 111 and is connected to the humidification pipe 107. The water storage box 113 is connected to the filter device 103 through a water pipe at the bottom of the filter device 103.

[0182] In one embodiment of the present invention, the refrigerator 10 may further include:

[0183] A wireless device is configured to receive a second control command sent by a mobile terminal and send the second control command sent by the mobile terminal to a control device; and to send data sent by the control device to the mobile terminal to the mobile terminal.

[0184] In some feasible embodiments, in order to establish a connection between the refrigerator 10 and the user's mobile terminal, the refrigerator 10 may also be equipped with a wireless device. This wireless device may connect to the mobile terminal via Bluetooth or via a wireless network. This embodiment of the invention does not limit this.

[0185] When a user needs to control the refrigerator 10, such as adjusting the temperature of the refrigerator 10 or turning on the fresh air system, they can perform the operation of generating a second control command on the mobile terminal; after the mobile terminal generates the second control command, it can send it to the wireless device of the refrigerator 10.

[0186] After receiving the second control command, the wireless device can send the second control command to the control device so that the control device can control the refrigerator 10 in response to the second control command.

[0187] In other feasible embodiments, the control device may also transmit information of the refrigerator 10 to a mobile terminal via a wireless device. For example, the control device may generate data from one or more of the following information: the current temperature of the refrigerator 10, the air quality of the storage compartment, the humidity of the storage compartment, the usage level of the filter element 109 of the filter device 103, and the usage level of the filter element 111 of the water storage device 106. The control device may then transmit the data to the mobile terminal via a wireless device so that the user can know the status of the refrigerator 10 on the mobile terminal.

[0188] In one embodiment of the present invention, the filter device 103 is further provided with a first external connector 114 and a second external connector 115;

[0189] The first external pipe 114 is used to discharge the air filtered by the filter device 103 to the fresh air intake pipe 104 and then to the refrigerator 10.

[0190] The second external pipe 115 is used to deliver air from outside the refrigerator 10 to the filter device 103. The filter device 103 is used to filter the air entering from the second external pipe 115 and discharge the filtered air into the storage cavity through the fresh air outlet pipe 105.

[0191] In some feasible embodiments, for external circulation, the filter device 103 may also be provided with a first external pipe 114 and a second external pipe 115. One end of the first external pipe 114 can be connected to the filter device, and the other end of the first external pipe 114 can be connected to the external environment of the refrigerator; one end of the second external pipe 115 can be connected to the filter device, and the other end of the second external pipe 115 can be connected to the external environment of the refrigerator.

[0192] For external circulation, the filter device 103 can filter the air obtained from the fresh air intake pipe 104 and discharge it into the refrigerator through the first external pipe 114; on the other hand, the filter device 103 can also obtain odorless air from the outside through the second external pipe 115, filter the air, and discharge it into the storage cavity through the fresh air outlet pipe.

[0193] The purpose of filtering outside air is to prevent germs from entering the storage cavity.

[0194] In one embodiment of the present invention, the first external pipe 114 is provided with a fourth valve, and the second external pipe 115 is provided with a fifth valve;

[0195] The control device is used to control the fourth valve and the fifth valve based on the detection data sent by the air detection device 102.

[0196] In some feasible embodiments, the refrigerator 10 can be equipped with both internal and external circulation. When the control device detects a small amount of odor in the storage cavity based on the detection data sent by the air detection device 102, it can first activate the internal circulation for filtration. For example, when the internal circulation is activated, the fourth and fifth valves can be closed. The filter device 103 can filter the air entering the storage cavity from the fresh air intake pipe 104, and then discharge the filtered air back into the storage cavity through the fresh air outlet pipe 105. Figure 2c As shown.

[0197] When the control device detects a strong odor in the storage cavity based on the detection data sent by the air detection device 102, it can activate the external air circulation. At this time, the control device can open the fourth and fifth valves. The filter device 103 can filter the air entering the storage cavity from the fresh air intake pipe 104 and discharge the filtered air to the refrigerator 10 through the first external pipe 114. Simultaneously, the filter device 103 can filter the air from the outside environment entering from the second external pipe 115 and discharge it into the storage cavity through the fresh air outlet pipe. When the external air circulation is activated, the filter device 103 can close the connection between the fresh air intake pipe 104 and the fresh air outlet pipe 105 to ensure proper airflow to the refrigerator's storage cavity.

[0198] Outside air enters the filter device 103 through the second external pipe 115. After filtering the outside air, the filter device 103 discharges the air into the storage cavity through the fresh air outlet 105. The air in the storage cavity enters the filter device 103 through the fresh air inlet 104, and after being filtered by the filter device 103, it is discharged from the refrigerator through the first external pipe 114. Figure 2d As shown.

[0199] For example, such as Figure 3 As shown, when the refrigerator starts running, the fresh air system initializes; after initialization, it can obtain second detection data from the air detection device and determine whether there is an odor in the air of the refrigerator's storage cavity based on the second detection data.

[0200] If there is an odor in the refrigerator's storage compartment, the health of the filter element can be further checked to see if it is not less than 10%. If the filter element's health is not less than 10%, the fresh air intake and exhaust pipes can be opened, and the first fan can be turned on to filter the air in the storage compartment until there is no odor. If the filter element's health is less than 10%, the user should be prompted to replace the filter element. After the user replaces the filter element, the fresh air intake and exhaust pipes can be opened.

[0201] When there is no odor in the air of the storage cavity, the first detection data can be obtained from the humidity detection device, and the humidity of the storage cavity can be determined based on the first detection data.

[0202] If the humidity in the storage cavity meets the preset humidity setting, the humidification pipe can be closed, and the fresh air intake pipe and fresh air outlet pipe can be opened, as well as the first fan can be turned on to dehumidify the air in the storage cavity.

[0203] If the humidity of the storage chamber meets the preset dry setting, the health of the filter element of the water storage device can be further checked to see if it is not less than 10%. If the health of the filter element of the water storage device is not less than 10%, the humidification pipe can be turned on and the second fan can be turned on to humidify the storage chamber. While humidifying the storage chamber, the humidity of the storage chamber can be determined based on the new first detection data.

[0204] If the health status of the filter cartridge in the water storage device is less than 10%, the user can be prompted to replace the filter cartridge; after the user replaces the filter cartridge, the humidification pipe can be turned on.

[0205] If the humidity in the storage cavity meets the preset appropriate humidity setting, the fresh air system can be controlled to enter standby mode until an odor is detected in the air of the storage cavity.

[0206] The conditions of suitable temperature, dryness, and humidity can be determined based on whether the humidity of the storage cavity is within a preset humidity range and its relationship with the first and second boundary values. When the humidity of the storage cavity is within the preset humidity range, the air in the storage cavity is considered to have suitable humidity. When the humidity of the storage cavity is less than the first boundary value, the air in the storage cavity is considered to be dry. When the humidity of the storage cavity is greater than the second boundary value, the air in the storage cavity is considered to be humid. This embodiment of the invention does not impose any restrictions on these conditions.

[0207] This invention also provides a method for controlling a refrigerator, which may include a humidity detection device, an air detection device, a control device, and a fresh air system; specifically, see [link to relevant documentation]. Figure 4 The flowchart illustrates the steps of this refrigerator control method, which may include the following steps:

[0208] Step 401: Obtain detection data collected from the humidity detection device and air detection device for the storage cavity of the refrigerator.

[0209] In some feasible embodiments, the refrigerator may be equipped with a humidity detection device and an air detection device; wherein, the humidity detection device can be used to detect the humidity of the refrigerator's storage cavity; and the air detection device can be used to detect the air in the storage cavity to detect whether there is an odor in the storage cavity.

[0210] The humidity detection device and the air detection device can be connected to the refrigerator's control device and send the detection data generated based on the detection process to the control device; the detection data output by the humidity detection device to the control device can be the humidity value of the storage cavity, and the detection data output by the air detection device to the control device can be used to indicate whether there is an odor in the storage cavity.

[0211] Before deodorizing or humidifying the refrigerator, the control device can obtain detection data collected from the humidity detection device and air detection device for the refrigerator's storage cavity.

[0212] Step 402: Based on the detection data, control the fresh air system to adjust the humidity of the storage cavity and / or filter the air in the storage cavity.

[0213] After receiving the detection data from the humidity detection device and the air detection device, the control device can control the refrigerator's fresh air system based on the detection data.

[0214] Specifically, after receiving the detection data sent by the humidity detection device and the air detection device, the control device can first identify and analyze the detection data sent by the humidity detection device and the air detection device, and generate a corresponding first control command based on the identification and analysis results. The first control command is used to control the fresh air system to adjust the humidity of the storage cavity and / or filter the air in the storage cavity.

[0215] After generating the first control command, the control device can send the first control command to the refrigerator's fresh air system to control the fresh air system.

[0216] Specifically, after receiving the first control command, the fresh air system can respond to the first control command and perform the corresponding operation. For example, when the first control command is to adjust the humidity of the storage cavity, the fresh air system can humidify or dehumidify the storage cavity. When the first control command is to filter the air in the storage cavity, the fresh air system can first extract the air from the storage cavity and then filter the air in the storage cavity. This embodiment of the invention does not limit this.

[0217] In this embodiment of the invention, detection data collected from the refrigerator's storage cavity is obtained from a humidity detection device and an air detection device. Based on the detection data, the fresh air system is controlled to adjust the humidity of the storage cavity and / or filter the air in the storage cavity. Through this embodiment of the invention, the air in the refrigerator's storage cavity can be automatically filtered, thereby removing odors from the storage cavity. Furthermore, after removing odors, the humidity of the storage cavity can be adjusted to ensure the humidity requirements of the food in the storage cavity, allowing the food to be stored fresh in the storage cavity.

[0218] Reference Figure 5 A flowchart illustrating the steps of another refrigerator control method according to an embodiment of the present invention is shown. The fresh air system of the refrigerator includes: a filter device, a water storage device, and a humidification pipe.

[0219] The filter device is connected to a fresh air inlet pipe and a fresh air outlet pipe. The water storage device is connected to the filter device and is used to store the water filtered out by the filter device. The humidification pipe is connected to the water storage device.

[0220] The control method may include the following steps:

[0221] Step 501: Obtain detection data collected from the humidity detection device and the air detection device for the storage cavity of the refrigerator; the detection data includes the first detection data corresponding to the humidity detection device and the second detection data corresponding to the air detection device.

[0222] In some feasible embodiments, the refrigerator may be equipped with a humidity detection device and an air detection device; wherein, the humidity detection device can be used to detect the humidity of the refrigerator's storage cavity; and the air detection device can be used to detect the air in the storage cavity to detect whether there is an odor in the storage cavity.

[0223] Humidity and air quality detection devices can be connected to the refrigerator's control unit and send the detection data generated based on the detection process to the control unit.

[0224] The humidity detection device outputs the humidity value of the storage cavity to the control device. For ease of subsequent differentiation, this detection data is used as the first detection data. The air detection device outputs the detection data to the control device to indicate whether there is an odor in the storage cavity. For ease of subsequent differentiation, this detection data is used as the second detection data.

[0225] Before deodorizing or humidifying the refrigerator, the control device can obtain first detection data from the humidity detection device and second detection data from the air detection device.

[0226] Step 502: Based on the second detection data, determine whether there is an odor in the air in the storage cavity.

[0227] In some feasible embodiments, after obtaining the second detection data, it can be determined whether there is an odor in the air in the storage cavity based on the second detection data.

[0228] Step 503: When there is an odor in the air in the storage cavity, open the fresh air intake pipe and the fresh air outlet pipe to filter the air entering the storage cavity from the fresh air intake pipe through the filter device, and to discharge the filtered air into the storage cavity through the fresh air outlet pipe.

[0229] When the control device determines that there is an odor in the air in the storage cavity based on the second detection data, the control device can open the fresh air intake pipe, the fresh air outlet pipe, and the filter device to filter the air entering the storage cavity from the fresh air intake pipe through the filter device, and to discharge the filtered air into the storage cavity through the fresh air outlet pipe.

[0230] For example, the air discharged into the storage cavity can be either filtered air drawn from the storage cavity or filtered air drawn from the outside, and the embodiments of the present invention do not limit this.

[0231] Step 504: When there is no odor in the air in the storage cavity, determine whether the humidity of the storage cavity is within the preset humidity range based on the first detection data; the preset humidity range consists of a first boundary value and a second boundary value, and the first boundary value is less than the second boundary value.

[0232] Conversely, if based on the second detection data it is determined that there is no odor in the air in the storage cavity, it can be further determined based on the first detection data whether the humidity of the storage cavity is within a preset humidity range; the preset humidity range can be composed of a first boundary value and a second boundary value, the first boundary value being less than the second boundary value; for example: the first boundary value is 30%, the second boundary value is 80%, then the preset humidity range is [30%, 80%].

[0233] Step 505: When the humidity of the storage chamber is not within the preset humidity range and the humidity of the storage chamber is less than the first boundary value, turn on the humidification pipe to discharge the water evaporated from the water storage device into the storage chamber through the humidification pipe.

[0234] If the humidity of the storage cavity is not within the preset humidity range, it can be further determined whether the humidity of the storage cavity is less than the first boundary value or greater than the second boundary value.

[0235] If the humidity in the storage cavity is less than the first boundary value, it means that the humidity in the storage cavity is low and the air in the storage cavity is too dry. At this time, the water in the water storage device can be evaporated into water vapor, and the humidification pipe can be turned on to discharge the water evaporated from the water storage device into the storage cavity through the humidification pipe to humidify the storage cavity.

[0236] Step 506: When the humidity of the storage cavity is not within the preset humidity range and the humidity of the storage cavity is greater than the second boundary value, open the fresh air intake pipe and the fresh air outlet pipe to filter the air entering the storage cavity from the fresh air intake pipe through the filter device, and discharge the filtered air into the storage cavity through the fresh air outlet pipe.

[0237] Conversely, if the humidity in the storage cavity is greater than the second boundary value, it indicates that the humidity in the storage cavity is high and the air in the storage cavity is humid. At this time, the fresh air intake pipe and the fresh air exhaust pipe can be opened to filter the air entering the storage cavity from the fresh air intake pipe through the filter device, and the filtered air can be discharged into the storage cavity through the fresh air exhaust pipe, thereby achieving dehumidification of the storage cavity.

[0238] In one embodiment of the present invention, the filter device is further provided with a first external pipe and a second external pipe; the first external pipe is used to discharge the air filtered by the filter device through the fresh air intake pipe to the refrigerator; the second external pipe is used to supply air from outside the refrigerator to the filter device, the filter device is used to filter the air entering from the second external pipe, and discharge the filtered air into the storage cavity through the fresh air outlet pipe.

[0239] The first external pipe is equipped with a fourth valve, and the second external pipe is equipped with a fifth valve;

[0240] The steps to open the fresh air intake pipe and the fresh air outlet pipe are as follows:

[0241] When there is an odor in the air in the storage cavity, determine the degree of odor in the air in the storage cavity; when the degree of odor meets the preset internal circulation conditions, close the fourth and fifth valves; when the degree of odor meets the preset external circulation conditions, open the fourth and fifth valves.

[0242] In some feasible embodiments, for external circulation, the filter device may also be provided with a first external pipe and a second external pipe. One end of the first external pipe can be connected to the filter device, and the other end of the first external pipe can be connected to the external environment of the refrigerator; one end of the second external pipe can be connected to the filter device, and the other end of the second external pipe can be connected to the external environment of the refrigerator.

[0243] For external circulation, the filter can filter the air obtained after the fresh air intake pipe and discharge it to the refrigerator through the first external pipe; on the other hand, the filter can also obtain odorless air from the outside through the second external pipe, filter the air, and discharge it into the storage cavity through the fresh air outlet pipe.

[0244] The purpose of filtering outside air is to prevent germs from entering the storage cavity.

[0245] In some feasible embodiments, the refrigerator can be equipped with both internal and external circulation. When the control device determines that there is an odor in the refrigerator's storage cavity, it can first determine the degree of odor in the air in the storage cavity. This degree of odor can be represented by the concentration of molecules corresponding to the odor; the higher the concentration, the higher the degree of odor, and the lower the concentration, the lower the degree of odor. This degree of odor can also be related to the molecules corresponding to the odor. For example, some molecules have a strong odor even at a very low concentration, while some molecules have a relatively weak odor even at a very high concentration. Based on this, internal circulation conditions and external circulation conditions can be set.

[0246] The odor intensity corresponding to the internal circulation condition is less than that corresponding to the external circulation condition. After receiving the detection data sent by the air detection device, the control device can determine the odor intensity of the air in the storage cavity based on the detection data; if the odor intensity of the air in the storage cavity is low and meets the internal circulation condition, the fourth and fifth valves can be closed, and only internal circulation can be operated.

[0247] If the odor level in the air in the storage cavity is high and meets the external circulation conditions, the fourth and fifth valves can be opened to run the external circulation. This embodiment of the invention does not impose any restrictions on this.

[0248] When the internal circulation is activated, the filter can filter the air entering the storage cavity from the fresh air intake pipe, and then discharge the filtered air back into the storage cavity through the fresh air outlet pipe.

[0249] When the external air circulation is activated, the control device can open the fourth and fifth valves. The filter device filters the air entering the storage cavity from the fresh air intake duct and exhausts the filtered air to the refrigerator through the first external air pipe. Simultaneously, the filter device filters ambient air entering from the second external air pipe and exhausts it into the storage cavity through the fresh air outlet duct. When the external air circulation is activated, the filter device can close the connection between the fresh air intake and outlet ducts to ensure proper airflow within the refrigerator's storage cavity.

[0250] Outside air enters the filter device through the second external pipe. After the filter device filters the outside air, it is discharged into the storage cavity through the fresh air outlet pipe. The air in the storage cavity enters the filter device through the fresh air inlet pipe, and after being filtered by the filter device, it is discharged from the refrigerator through the first external pipe.

[0251] In this embodiment of the invention, detection data collected from the storage cavity of the refrigerator is obtained from a humidity detection device and an air detection device; the detection data includes first detection data corresponding to the humidity detection device and second detection data corresponding to the air detection device; based on the second detection data, it is determined whether there is an odor in the air of the storage cavity; when there is an odor in the air of the storage cavity, the fresh air intake pipe and the fresh air outlet pipe are opened to filter the air entering the storage cavity from the fresh air intake pipe through the filter device, and to discharge the filtered air into the storage cavity through the fresh air outlet pipe; when there is no odor in the air of the storage cavity, based on the first detection data, it is determined whether the storage cavity is odorless. The system checks whether the humidity is within a preset humidity range. This preset humidity range consists of a first boundary value and a second boundary value, where the first boundary value is less than the second boundary value. When the humidity in the storage cavity is not within the preset humidity range and is less than the first boundary value, the humidification pipe is activated to drain water evaporated from the water storage device into the storage cavity. When the humidity in the storage cavity is not within the preset humidity range and is greater than the second boundary value, the fresh air intake pipe and fresh air outlet pipe are activated to filter the air entering the storage cavity from the fresh air intake pipe and to discharge the filtered air into the storage cavity through the fresh air outlet pipe. Through this embodiment of the invention, the air in the refrigerator's storage cavity can be automatically filtered to remove odors. Furthermore, after removing odors, the humidity in the storage cavity can be adjusted to ensure the humidity requirements of the food in the storage cavity, allowing for safe and fresh storage.

[0252] Reference Figure 6 The diagram illustrates a flowchart of another refrigerator control method according to an embodiment of the present invention. The control method may include the following steps:

[0253] Step 601: Obtain detection data collected from the humidity detection device and air detection device for the storage cavity of the refrigerator.

[0254] In some feasible embodiments, the refrigerator may be equipped with a humidity detection device and an air detection device; wherein, the humidity detection device can be used to detect the humidity of the refrigerator's storage cavity; and the air detection device can be used to detect the air in the storage cavity to detect whether there is an odor in the storage cavity.

[0255] Humidity and air quality detection devices can be connected to the refrigerator's control unit and send the detection data generated based on the detection process to the control unit.

[0256] The humidity detection device outputs the humidity value of the storage cavity to the control device. For ease of subsequent differentiation, this detection data is used as the first detection data. The air detection device outputs the detection data to the control device to indicate whether there is an odor in the storage cavity. For ease of subsequent differentiation, this detection data is used as the second detection data.

[0257] Before deodorizing or humidifying the refrigerator, the control device can obtain first detection data from the humidity detection device and second detection data from the air detection device.

[0258] Step 602: Based on the second detection data, determine whether there is an odor in the air in the storage cavity.

[0259] In some feasible embodiments, after obtaining the second detection data, it can be determined whether there is an odor in the air in the storage cavity based on the second detection data.

[0260] Step 603: The filter device is equipped with a filter element. When there is an odor in the air in the storage cavity, the health of the filter element of the filter device is determined.

[0261] When the control device determines that there is an odor in the air in the storage cavity based on the second detection data, it can first obtain the health status of the filter element set in the filter device; this health status can be obtained from the first self-test device set for the filter element of the filter device.

[0262] In one embodiment of the present invention, the filtration device further includes a first disinfection unit, and the above method may further include:

[0263] The first disinfection unit is controlled to disinfect the filter element in the filtration device.

[0264] In some feasible embodiments, the control device can control the first disinfection unit to disinfect the filter element in the filter device after the filter device has been running for a period of time.

[0265] Step 604: When the health of the filter element of the filter device is lower than the preset health level, an alarm is issued to the filter element of the filter device.

[0266] In some feasible embodiments, if the health of the filter element of the filter device is lower than the preset health level, it can be indicated that the filter element is unhealthy and cannot be used. At this time, the control device can issue an alarm to the filter element of the filter device; for example, by sending an alarm to the user's mobile terminal for the filter element.

[0267] Step 605: When the health of the filter element of the filter device is not lower than the preset health level, open the fresh air intake pipe and the fresh air outlet pipe.

[0268] If the health level of the filter element is not lower than the preset health level, it means that the filter element is healthy and can continue to be used. At this time, the control device can open the fresh air inlet pipe, the fresh air outlet pipe, and the filter element to filter the air.

[0269] Step 606: When there is no odor in the air in the storage cavity, determine whether the humidity of the storage cavity is within the preset humidity range based on the first detection data.

[0270] If, based on the second detection data, it is determined that there is no odor in the air of the storage cavity, it can be further determined, based on the first detection data, whether the humidity of the storage cavity is within the preset humidity range.

[0271] Step 607: The water storage device is equipped with a filter element. When the humidity of the storage chamber is not within the preset humidity range and the humidity of the storage chamber is less than the first boundary value, the health of the filter element of the water storage device is determined.

[0272] If the humidity of the storage cavity is not within the preset humidity range, it can be further determined whether the humidity of the storage cavity is less than the first boundary value or greater than the second boundary value.

[0273] If the humidity in the storage chamber is less than the first threshold value, it indicates that the humidity in the storage chamber is low and the air in the storage chamber is too dry. In this case, the health status of the filter element of the water storage device can be determined first. This health status can be obtained from the second inspection device installed for the filter element of the water storage device.

[0274] In one embodiment of the present invention, the water storage device includes a second disinfection unit, and the above method may further include:

[0275] The second disinfection unit is controlled to disinfect the filter element of the water storage device.

[0276] In some feasible embodiments, the control device can control the second disinfection unit to disinfect the filter element in the water storage device after the water storage device has been running for a period of time.

[0277] Step 608: When the health level of the filter element of the water storage device is lower than the preset health level, an alarm is issued to the filter element of the water storage device.

[0278] In some feasible embodiments, if the health of the filter cartridge of the water storage device is lower than the preset health level, it can be indicated that the filter cartridge is unhealthy and cannot be used. At this time, the control device can issue an alarm to the filter cartridge of the water storage device; for example, by sending an alarm to the user's mobile terminal for the filter cartridge.

[0279] Step 609: When the health level of the filter element of the water storage device is not lower than the preset health level, turn on the humidification pipe.

[0280] If the health level of the filter element in the water storage device is not lower than the preset health level, it means that the filter element is healthy and can continue to be used. At this time, the water in the water storage device can be evaporated into water vapor, and the humidification pipe can be turned on to discharge the water evaporated from the water storage device into the storage chamber through the humidification pipe to humidify the storage chamber.

[0281] In one embodiment of the present invention, the refrigerator further includes a display device, and the above method may further include:

[0282] The health status of the filter element is displayed on the display device.

[0283] In some feasible embodiments, after determining the health status of the filter element of the filtration device, the control device can display the health status of the filter element on the display device; in addition, after determining the health status of the filter element of the water storage device, the control device can also display the health status of the filter element on the display device, and the embodiments of the present invention do not limit this.

[0284] Step 610: When the humidity of the storage cavity is not within the preset humidity range and the humidity of the storage cavity is greater than the second boundary value, open the fresh air intake pipe and the fresh air outlet pipe.

[0285] If the humidity in the storage cavity is greater than the second boundary value, it indicates that the humidity in the storage cavity is high and the air in the storage cavity is humid. At this time, the fresh air intake pipe and the fresh air exhaust pipe can be opened to filter the air through the filter device, thereby achieving dehumidification of the storage cavity.

[0286] It should be noted that before performing step 310 to open the fresh air intake pipe and the fresh air outlet pipe, the health of the filter element of the filter device can be checked first. If the health of the filter element of the filter device is not lower than the preset health level, it means that the filter element is healthy and can continue to be used. At this time, the control device can open the fresh air intake pipe, the fresh air outlet pipe, and the filter device.

[0287] Conversely, if the health of the filter element of the filter device is lower than the preset health level, an alarm will be issued to the filter element of the filter device. This embodiment of the invention does not limit this.

[0288] In one embodiment of the present invention, the storage cavity includes at least a first sub-storage cavity and a second sub-storage cavity; the fresh air intake pipe includes at least a first air inlet corresponding to the first sub-storage cavity and a second air inlet corresponding to the second sub-storage cavity; the fresh air outlet pipe includes at least a first air outlet corresponding to the first sub-storage cavity and a second air outlet corresponding to the second sub-storage cavity.

[0290] Sub-step 11: Based on the second detection data, determine whether there is an odor in the air in the first sub-storage cavity and the second sub-storage cavity.

[0291] In some feasible embodiments, after obtaining the second detection data, it can be determined first based on the second detection data whether the air in the first sub-storage cavity has an odor or the air in the second sub-storage cavity has an odor.

[0292] Based on sub-step 11, the step of "opening the fresh air intake pipe and the fresh air outlet pipe" in step 605 can be achieved through the following sub-steps:

[0293] Sub-step 21: When there is an odor in the air in the first sub-storage cavity, open the first air inlet and the first air outlet.

[0294] If there is an odor in the air in the first sub-storage cavity, the first air inlet and the first air outlet can be opened to filter the air in the first sub-storage cavity.

[0295] Sub-step 22: When there is an odor in the air in the second sub-storage cavity, open the second air inlet and the second air outlet.

[0296] If there is an odor in the air in the second sub-storage chamber, the second air inlet and the second air outlet can be opened to filter the air in the second sub-storage chamber.

[0297] In one embodiment of the present invention, the humidification pipe includes a third air outlet corresponding to the first sub-storage cavity and a fourth air outlet corresponding to the second sub-storage cavity; step 606 can be implemented by the following sub-steps:

[0299] In some feasible embodiments, after obtaining the first detection data, it can be determined whether the humidity of the first sub-storage cavity and the second sub-storage cavity is within a preset humidity range based on the first detection data.

[0300] Based on sub-step 31, step 609 can be implemented through the following sub-steps:

[0301] Sub-step 41: When the humidity of the first sub-storage chamber is not within the preset humidity range and the humidity of the first sub-storage chamber is less than the first boundary value, open the third air outlet.

[0302] If the humidity in the first sub-storage cavity is not within the preset humidity range and the humidity in the first sub-storage cavity is less than the first boundary value, the third air outlet can be opened to humidify the first sub-storage cavity.

[0303] If the humidity in the first sub-storage cavity is not within the preset humidity range and the humidity in the first sub-storage cavity is greater than the second boundary value, the first air inlet and the first air outlet can be opened to dehumidify the air in the first sub-storage cavity.

[0304] Sub-step 42: When the humidity of the second sub-storage chamber is not within the preset humidity range and the humidity of the storage chamber is less than the first boundary value, open the fourth air outlet.

[0305] If the humidity in the second sub-storage chamber is not within the preset humidity range and the humidity in the second sub-storage chamber is less than the first boundary value, the fourth air outlet can be opened to humidify the second sub-storage chamber.

[0306] If the humidity in the second sub-storage cavity is not within the preset humidity range and the humidity in the second sub-storage cavity is greater than the second boundary value, the second air inlet and the second air outlet can be opened to dehumidify the air in the second sub-storage cavity.

[0307] In some feasible embodiments, when there is no odor in the air of the storage cavity and the humidity of the storage cavity is within a preset humidity range, the control device can control the fresh air system to enter a low-power standby mode, for example, by turning off the fan, air inlet pipe, air outlet pipe and humidification pipe.

[0308] In one embodiment of the present invention, the method further includes:

[0309] The system controls the fresh air system in response to a second control command sent from the mobile terminal.

[0310] In some feasible embodiments, after receiving the second control command from the mobile terminal, the control device can control the fresh air system in response to the second control command, such as controlling the fresh air system to dehumidify the storage cavity, controlling the fresh air system to humidify the storage cavity, etc. The embodiments of the present invention do not limit this.

[0311] In this embodiment of the invention, detection data collected from the humidity detection device and the air detection device for the storage cavity of the refrigerator are obtained; based on the second detection data, it is determined whether there is an odor in the air of the storage cavity; the filter device is equipped with a filter element, and when there is an odor in the air of the storage cavity, the health status of the filter element is determined; when the health status of the filter element is lower than a preset health status, an alarm is issued for the filter element; when the health status of the filter element is not lower than the preset health status, the fresh air intake pipe and the fresh air outlet pipe are opened; when there is no odor in the air of the storage cavity, based on the first detection data... The system measures data to determine whether the humidity in the storage cavity is within a preset humidity range. A filter element is installed in the water storage device. When the humidity in the storage cavity is not within the preset humidity range and is less than a first boundary value, the health of the filter element is determined. When the health of the filter element is lower than a preset health value, an alarm is triggered.
