[0050] The embodiments will be described in detail below with examples shown in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following embodiments do not represent all the embodiments consistent with the present application. They are only examples of systems and methods consistent with some aspects of the present application as detailed in the claims.

[0051] The humidity adjustment device starts the humidification or dehumidification function through a preset time period or a fixed humidity threshold. When the humidity inside the refrigerator is lower than the set value, the humidifier will automatically start to increase the humidity, and when the humidity exceeds the upper limit, the dehumidification mechanism will be started to reduce the humidity. Although this adjustment method can meet the basic humidity requirements to some extent, it is easy to cause over-humidification or over-dehumidification due to the lack of real-time monitoring and dynamic adjustment capability, resulting in low humidity control accuracy.

[0052] Some embodiments of the present application provide a humidity adjustment device, referring to Figure 1 , comprising: a first adjustment chamber, a second adjustment chamber and a third adjustment chamber, the width of the first adjustment chamber, the second adjustment chamber and the third adjustment chamber is the same, the length can be set according to the actual situation, the shape is rectangular, for example, the first adjustment chamber, the second adjustment chamber and the third adjustment chamber are respectively fixed by four fixed plates.

[0053] For the first adjusting chamber, the first fixed plate is connected with the second fixed plate and parallel with the third fixed plate, the second fixed plate is connected with the third fixed plate and parallel with the fourth fixed plate, and the third fixed plate is connected with the fourth fixed plate perpendicularly. It can be understood that, due to the connection of the three adjusting chambers, the fourth fixed plate of the first adjusting chamber can be used as the second fixed plate of the second adjusting chamber, and in addition, the second adjusting chamber includes three fixed plates, i.e. the fifth fixed plate, the sixth fixed plate and the seventh fixed plate, the fifth fixed plate is connected with the fourth fixed plate and parallel with the sixth fixed plate, the sixth fixed plate is connected with the seventh fixed plate perpendicularly, and the seventh fixed plate is parallel with the fourth fixed plate.

[0054] For the third adjusting chamber, the seventh fixed plate of the second adjusting chamber can be used as the second fixed plate of the third adjusting chamber, and in addition, the third adjusting chamber includes three fixed plates, i.e. the eighth fixed plate, the ninth fixed plate and the tenth fixed plate, the eighth fixed plate is connected with the seventh fixed plate and parallel with the ninth fixed plate, the ninth fixed plate is connected with the tenth fixed plate perpendicularly, and the tenth fixed plate is parallel with the seventh fixed plate.

[0055] The first adjusting chamber includes the first air inlet 110 and the humidity sensor 120. The first air inlet 110 can be arranged on the second fixed plate and used to suck air and introduce external air into the system. For example, when the humidity adjusting device is arranged in a refrigerator, the first air inlet 110 can be connected with the refrigeration compartment and used to introduce air in the refrigeration compartment into the humidity adjusting device. The humidity sensor 120 is used to detect the relative humidity of the air, i.e. the relative humidity of the air entering through the first air inlet 110. For example, the relative humidity of the air introduced from the refrigeration compartment is detected.

[0056] The second adjusting chamber is connected with the first adjusting chamber and includes the second air inlet 210 and the humidity adjusting assembly 230. The second air inlet 210 can be arranged on the fourth fixed plate, i.e. between the first adjusting chamber and the second adjusting chamber, and used to allow air to flow from the first adjusting chamber into the second adjusting chamber. The humidity adjusting assembly 230 is arranged in the second adjusting chamber, e.g. on the sixth fixed plate, and used to humidify or dehumidify the air as needed to ensure that the relative humidity of the air meets the preset standard. The air enters the humidity adjusting assembly 230 from the first adjusting chamber through the second air inlet 210, and the humidity adjusting assembly 230 is responsible for the humidification or dehumidification of the air.

[0057] In some embodiments, the humidity adjusting assembly 230 can include a humidity adjusting sheet and / or an electrochemical humidity adjusting. The humidity adjusting sheet is made of hygroscopic materials such as silica gel, activated carbon, molecular sieve, etc. These materials have strong hygroscopic properties and can absorb water in a high humidity environment and release water in a low humidity environment. The humidity adjusting sheet is a passive adjusting assembly that does not require an external power source or mechanical power. When the ambient humidity is high, the adjusting sheet will automatically absorb excess water; when the ambient humidity is low, the adjusting sheet will release the stored water, thereby achieving the effect of balancing humidity.

[0058] The electrochemical humidity adjusting assembly uses electrochemical reactions to achieve humidity adjustment, including two electrodes and an electrolyte solution. When a voltage is applied, water molecules will undergo electrochemical reactions on the electrode surface, thereby achieving humidification or dehumidification. The electrochemical humidity adjusting assembly is an active adjusting assembly that can accurately control humidity by changing the current size and direction. For example, a forward current can separate water molecules from the air and store them in the electrolyte, achieving dehumidification; a reverse current can release water molecules stored in the electrolyte back into the air, achieving humidification.

[0059] In some embodiments, the second adjusting chamber includes a first fence assembly 240 and a circulating fan 220. The first fence assembly 240 includes a plurality of fences that are staggered within the second adjusting chamber. The fences are used to adjust the direction of the gas flow and extend the gas flow path, facilitating the removal of the gas.

[0060] Specifically, the fences enable the air entering the second adjusting chamber to be evenly dispersed. After the air enters the first adjusting chamber through the first air inlet 110, the circulating fan 220 sucks it in and sends it into the second adjusting chamber. The staggered distribution of the fences forces the air to be evenly dispersed before entering the humidity adjusting assembly 230, avoiding the concentration of the airflow at a certain point and ensuring that the air is evenly treated in the humidity adjusting assembly 230. Moreover, the fences can prevent the air from passing directly without being fully adjusted, avoiding the phenomenon of airflow short circuiting and ensuring that every part of the air is treated by the humidity adjusting assembly 230.

[0061] The fences extend the path of the airflow within the second adjusting chamber, increasing the contact time of the air with the humidity adjusting assembly 230, which can ensure that the water in the air is more fully absorbed or released, improving the efficiency and effectiveness of humidity adjustment. By extending the airflow path, the residence time of the air in the humidity adjusting assembly 230 is increased, making the humidity adjustment more accurate.

[0062] The circulating fan 220 connects the first adjusting chamber and the second adjusting chamber, and is used to suck the air in the first adjusting chamber and send it into the humidity adjusting assembly 230 in the second adjusting chamber, ensuring that the air is fully mixed and adjusted.

[0063] Air from the first conditioning chamber to the second conditioning chamber, for example, air is sucked into the first conditioning chamber through the first air inlet 110, and the relative humidity of the air entering the first conditioning chamber is detected by the humidity sensor 120. If the detected humidity is not within the preset range, the second air inlet 210 is opened to allow air to enter the second conditioning chamber, and the circulating fan 220 is started to suck the air in the first conditioning chamber and send it into the second conditioning chamber. The air entering the second conditioning chamber first passes through the first fence assembly 240, and the humidity adjusting assembly 230 adjusts the humidity of the air as needed to ensure that the relative humidity of the air reaches the preset range.

[0064] The second conditioning chamber is connected to the third conditioning chamber, and the third conditioning chamber is a processing area for air after humidity adjustment. The third conditioning chamber includes a third air inlet 310 and an air outlet 330. The third air inlet 310 can be provided on the seventh fixed plate and located between the second conditioning chamber and the third conditioning chamber, so that the air after humidity adjustment can flow into the third conditioning chamber. The air outlet 330 can be provided on the tenth fixed plate and located in the third conditioning chamber, which is the outlet for the air after humidity adjustment to leave the humidity adjusting device.

[0065] In some embodiments, the first air inlet 110 and the second air inlet 210 are arranged in a first direction, and the third air inlet 310 is arranged in a second direction. For example, the first air inlet 110 and the second air inlet 210 are arranged on the left side, and the third air inlet 310 is arranged on the right side. The third air inlet 310 can be arranged on the same side as the humidity adjusting assembly 230. The third air inlet 310 and the air outlet 330 are arranged in opposite directions.

[0066] In some embodiments, the third conditioning chamber further includes an odor sensor 320 arranged on the inner wall of the third conditioning chamber. The odor sensor 320 detects the concentration of odor molecules in the air flowing out of the third air inlet 310. The odor sensor 320 can monitor the odor in the air in real time to ensure the quality of the air discharged.

[0067] Air from the second conditioning chamber to the third conditioning chamber, for example, air after treatment by the humidity adjusting assembly 230 enters the third conditioning chamber through the third air inlet 310. The concentration of odor molecules is detected by the odor sensor 320. If it meets the preset range, it is discharged from the air outlet 330 after passing through the second fence assembly 340. The fence can prolong the path of air flow in the third conditioning chamber and increase the residence time of air in the third conditioning chamber, which helps the odor molecules in the air to fully contact the odor sensor 320 and improves the accuracy of odor detection.

[0068] Based on the above-mentioned humidity adjusting device, some embodiments of the present application further provide a refrigerator, which comprises a housing and a controller. The housing is provided with the above-mentioned humidity adjusting device.

[0069] Referring to Figure 2 , the controller is configured to:

[0070] obtaining a first humidity detection result, the first humidity detection result being a first humidity value of air in the first conditioning chamber detected by the humidity sensor;

[0071] if the first humidity value is not within the preset humidity range, starting a first conditioning mode, and sending an instruction to the circulating fan and the humidity conditioning assembly to control the circulating fan and the humidity conditioning assembly to start, the first conditioning mode being a mode of closing the first air outlet and the third air outlet, and opening the second air outlet;

[0072] obtaining a second humidity detection result, the second humidity detection result being a second humidity value of the air in the first conditioning chamber after being conditioned by the humidity conditioning assembly detected by the humidity sensor;

[0073] if the second humidity value is within the preset humidity range, starting a second conditioning mode, and sending an instruction to the humidity conditioning assembly to control the humidity conditioning assembly to close, the second conditioning mode being a mode of closing the first air outlet, and opening the second air outlet and the third air outlet.

[0074] The preset humidity range can be set according to actual storage requirements or environmental requirements, for example, the humidity range is 40-60%.

[0075] After the refrigerator is started, the controller starts to work and is ready to receive the detection result of the humidity sensor, i.e., the humidity sensor arranged in the first detection chamber, the controller obtains the first humidity value of the air in the first conditioning chamber from the humidity sensor, judges whether the current humidity is within the preset humidity range, if the first humidity value is not within the preset humidity range, the controller starts the first conditioning mode, and the first conditioning mode is to deliver the air from the first conditioning chamber to the second conditioning chamber to adjust the humidity value of the air by the humidity conditioning assembly.

[0076] In the process of conditioning, the humidity sensor detects the humidity in real time, i.e., the second humidity value, if the second humidity value is within the preset humidity range, the controller starts the second conditioning mode, and the second conditioning mode is to deliver the air from the second conditioning chamber to the third conditioning chamber to be discharged through the air outlet.

[0077] Through the cooperation of the humidity sensor and the controller to dynamically adjust the mode of the damper, high-precision humidity control can be realized to ensure that the humidity inside the refrigerator is always within the preset range.

[0078] In some embodiments, at least a first chamber is arranged in the shell;

[0079] The controller is further configured to:

[0080] In response to the power of the refrigerator being turned on, the fourth adjustment mode is started, and an instruction is sent to the circulating fan to control the circulating fan to start. The first adjustment mode is a mode in which the second air outlet is closed, and the first air outlet and the third air outlet are opened.

[0081] To remove the gas in the humidity adjusting device, the circulating fan starts to suck external air from the first air outlet into the first adjusting chamber. Since the second air outlet is closed, the air cannot directly enter the second adjusting chamber from the first adjusting chamber. Therefore, the air circulates in the first adjusting chamber and does not enter the second adjusting chamber. The original gas in the second adjusting chamber enters the third adjusting chamber from the third air outlet and is discharged from the air outlet. In this way, the original gas (which may contain odors, air with excessively high or low humidity) in the second adjusting chamber can be discharged, ensuring that new air enters the system and preparing for subsequent humidity adjustment.

[0082] Through the fourth adjustment mode, the refrigerator can quickly discharge the original gas in the second adjusting chamber when powered on, thereby improving the accuracy and effectiveness of humidity control.

[0083] As a device for storing food materials at home, the refrigerator stores a variety of food materials, which may produce various odors, including the smell of the food materials themselves, the smell of the refrigerator materials, and the smell of microbial metabolism. These odors mixed together can cause the food materials in the refrigerator to have a cross smell, affecting the quality of the food materials. The way to remove odors in the refrigerator can be divided into ordinary operation and intelligent operation. The ordinary operation mode is that the deodorizing device in the refrigerator is turned on according to certain inherent logic. The intelligent operation mode is that the refrigerator is equipped with an odor sensor and a deodorizing device. When the odor sensor detects that the odor molecules reach a certain concentration, the deodorizing device is turned on to remove the odor molecules.

[0084] The ordinary operation mode can remove odors to some extent, but has drawbacks. The deodorizing device cannot determine whether the odor has been completely removed, which may result in incomplete removal of the odor. When the odor is very strong, the deodorizing device cannot immediately start purification, resulting in poor user experience. The intelligent operation mode uses an odor sensor to identify the concentration of odors in the refrigerator in real time. The deodorizing device can be intelligently controlled according to the concentration of odors. The odor sensor is based on the physical and chemical reaction between a sensitive material and odor molecules, which causes a change in the electrochemical signal of the material, and then determines the concentration of odor molecules. However, the relative humidity of the space affects this physical and chemical reaction, resulting in a large difference in the electrochemical signal under the same concentration of odor molecules, thereby reducing the accuracy of the odor sensor.

[0085] In some embodiments, a deodorizing assembly is provided in the refrigerator. The deodorizing assembly is a device for removing odors in the refrigerator, which can be an activated carbon filter, a photocatalyst purifier, an ion generator, etc.

[0086] In some embodiments, the humidity sensor is further configured to detect a relative humidity of an environment around the odor sensor, and the odor sensor is further configured to detect an odor in the refrigerator, generate an electrochemical signal based on a physical and chemical reaction between the sensitive material and the odor molecules, and determine a concentration of the odor molecules.

[0087] The controller is further configured to:

[0088] obtain a relative humidity detection result, the relative humidity detection result being a relative humidity value within a preset range of the odor sensor detected by the humidity sensor;

[0089] if the relative humidity value is not within the humidity working range, send an instruction to the humidity adjusting device to control the humidity adjusting device to start.

[0090] It can be understood that the humidity sensor is arranged at a position where the relative humidity value within a preset range of the odor sensor can be detected, and different humidity detection results and concentration detection results are obtained by the humidity sensor and the odor sensor at different times.

[0091] The relative humidity around the odor sensor is detected by the humidity sensor, so that the relative humidity in the area is within a preset humidity working range, thereby eliminating the influence of humidity on the electrochemical signal and improving the accuracy of the odor sensor. If the relative humidity exceeds the humidity working range, the humidity adjusting device is automatically started to adjust the humidity, so as to ensure that the detection result of the odor sensor is accurate and reliable.

[0092] In some embodiments, the controller is further configured to:

[0093] if the relative humidity value is within the humidity working range, obtain a second concentration detection result, the second concentration detection result being a second odor molecule concentration value within the shell detected by the odor sensor;

[0094] if the second odor molecule concentration value is greater than or equal to a second concentration threshold value, send an instruction to the odor removal component to control the odor removal component to start.

[0095] When the relative humidity value is within the humidity working range, it indicates that the odor sensor is working under suitable humidity conditions at this time, and the detection result has high accuracy. When the odor molecule concentration value is greater than or equal to the threshold concentration value, the odor removal module is started.

[0096] To improve the odor removal efficiency, in some embodiments, the controller is further configured to:

[0097] obtain a first concentration detection result, the first concentration detection result being a first odor molecule concentration value of a third adjusting chamber detected by the odor sensor;

[0098] If the first odor molecule concentration value is greater than or equal to the first concentration threshold value, a third adjustment mode is started, and a command is sent to the odor removal assembly to control the odor removal assembly to start, the third adjustment mode being a mode of opening the first air port, the second air port, and the third air port.

[0099] If the first odor molecule concentration value is greater than or equal to the first concentration threshold value, the controller starts the third adjustment mode, and opens the first air port, the second air port, and the third air port, so that air can flow freely between the first adjustment chamber, the second adjustment chamber, and the third adjustment chamber, and the odor removal assembly starts to remove odor molecules in the third adjustment chamber. In the third adjustment mode, all air ports are opened, so that air can flow freely between the adjustment chambers, and the odor removal efficiency is improved.

[0100] The first concentration threshold value can be the same as or different from the second concentration threshold value. The first concentration threshold value is a concentration threshold value set in the third adjustment chamber, and the second concentration threshold value is a concentration threshold value set in the refrigerator shell. Both can be set according to actual needs.

[0101] Based on the above-described refrigerator, some embodiments of the present application further provide a humidity adjustment method, comprising:

[0102] Obtaining a first humidity detection result, the first humidity detection result being a first humidity value of air in the first adjustment chamber detected by a humidity sensor;

[0103] If the first humidity value is not within a preset humidity range, a first adjustment mode is started, and a command is sent to the circulating fan and the humidity adjustment assembly to control the circulating fan and the humidity adjustment assembly to start, the first adjustment mode being a mode of closing the first air port and the third air port, and opening the second air port;

[0104] Obtaining a second humidity detection result, the second humidity detection result being a second humidity value of air in the first adjustment chamber after being adjusted by the humidity adjustment assembly, the second humidity value being detected by the humidity sensor;

[0105] If the second humidity value is within the preset humidity range, a second adjustment mode is started, and a command is sent to the humidity adjustment assembly to control the humidity adjustment assembly to close, the second adjustment mode being a mode of closing the first air port 110, and opening the second air port and the third air port.

[0106] In some embodiments, the humidity adjustment method further comprises: before obtaining the first humidity detection result, in response to the power of the refrigerator being turned on, a fourth adjustment mode is started, and a command is sent to the circulating fan to control the circulating fan to start, the first adjustment mode being a mode of closing the second air port, and opening the first air port and the third air port.

[0107] Based on the above-described refrigerator, see Figure 3The refrigerator deodorization method provided by the embodiments of the present application comprises the following steps:

[0108] obtaining a relative humidity detection result, the relative humidity detection result being a relative humidity value in a preset range of the odor sensor detected by the humidity sensor;

[0109] if the relative humidity value is within the humidity working range, obtaining a second concentration detection result, the second concentration detection result being a second odor molecule concentration value in the shell detected by the odor sensor;

[0110] if the second odor molecule concentration value is greater than or equal to a second concentration threshold value, sending an instruction to the deodorization assembly to control the deodorization assembly to start.

[0111] The method further comprises the following step: if the relative humidity value is not within the humidity working range, wherein the humidity working range can be 40-70%, sending an instruction to the humidity adjusting device to control the humidity adjusting device to start, the humidity adjusting device being the humidity adjusting device provided in the above embodiments, and the control method of the humidity adjusting device can be according to the above embodiments of the refrigerator.

[0112] It can be understood that if the second odor molecule concentration value is less than the second concentration threshold value, the deodorization can be ended.

[0113] The method can make the odor sensor run in a suitable humidity by adjusting the relative humidity of the working environment of the odor sensor to 40-70%, can accurately identify the odor concentration in the refrigerator environment, can accurately control the operation of the deodorization device, and can bring a good deodorization experience to the user.
