[0002] Temperature and humidity control of the refrigerator's internal environment can be used to keep food fresh. In a refrigerator, humidity control devices can be integrated into the refrigerator, for example, in the fruit and vegetable storage area, to maintain an appropriate humidity level to prevent food from drying out and losing freshness. These humidity control devices manage the humidity in the storage room by adjusting the air circulation path and humidity control elements.

[0003] The humidity control device activates the humidification or dehumidification function through a preset time period or a fixed humidity threshold.

When the humidity exceeds the set upper limit, the dehumidification mechanism will be activated to reduce the humidity.

[0004] Although this adjustment method can meet the basic humidity requirements to a certain extent, due to the lack of real-time monitoring and dynamic adjustment capabilities, it is easy to cause over-humidification or over-dehumidification, resulting in low humidity control accuracy.

[0050] The following embodiments are described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following embodiments do not represent all implementations 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 activates 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 turn on to increase the humidity. When the humidity exceeds the set upper limit, the dehumidification mechanism will be activated to reduce the humidity. Although this adjustment method can meet the basic humidity requirements to a certain extent, due to the lack of real-time monitoring and dynamic adjustment capabilities, it is easy to cause over-humidification or over-dehumidification, resulting in low humidity control accuracy.

[0052] Some embodiments of the present application provide a humidity control device, see Figure 1 , including: a first regulating chamber, a second regulating chamber and a third regulating chamber. The first regulating chamber, the second regulating chamber and the third regulating chamber have the same width, and the length can be set according to actual conditions. The shape is rectangular. Exemplarily, the first regulating chamber, the second regulating chamber and the third regulating chamber are respectively fixed by four fixing plates.

[0053] For the first regulating chamber, the first fixing plate is connected to the second fixing plate and is parallel to the third fixing plate, the second fixing plate is connected to the third fixing plate and is parallel to the fourth fixing plate, and the third fixing plate is vertically connected to the fourth fixing plate. It can be understood that since the three regulating chambers are connected, the fourth fixing plate of the first regulating chamber can be used as the second fixing plate of the second regulating chamber. Then, in addition to this, the second regulating chamber includes three fixing plates, namely the fifth fixing plate, the sixth fixing plate and the seventh fixing plate. The fifth fixing plate is connected to the fourth fixing plate and is parallel to the sixth fixing plate, the sixth fixing plate is vertically connected to the seventh fixing plate, and the seventh fixing plate is parallel to the fourth fixing plate.

[0054] For the third regulating chamber, the seventh fixed plate of the second regulating chamber can be used as the second fixed plate of the third regulating chamber. Then, in addition to this, the third regulating chamber includes three fixed plates, namely the eighth fixed plate, the ninth fixed plate and the tenth fixed plate. The eighth fixed plate is connected to the seventh fixed plate and is parallel to the ninth fixed plate. The ninth fixed plate is vertically connected to the tenth fixed plate, and the tenth fixed plate is parallel to the seventh fixed plate.

[0055] The first conditioning chamber includes a first air outlet 110 and a humidity sensor 120. The first air outlet 110 can be arranged on the second fixed plate to inhale air and introduce external air into the system. For example, if the humidity conditioning device is arranged in a refrigerator, the first air outlet 110 can be connected to the refrigerating compartment to introduce the air in the refrigerating compartment into the humidity conditioning device. The humidity sensor 120 is used to detect the relative humidity of the air, that is, to detect the relative humidity of the air entering through the first air outlet 110. For example, the relative humidity of the air introduced into the refrigerating compartment is detected.

[0056] The second conditioning chamber is connected to the first conditioning chamber, and includes a second air outlet 210 and a humidity regulating assembly 230. The second air outlet 210 can be arranged on the fourth fixed plate, that is, between the first conditioning chamber and the second conditioning chamber, allowing air to flow from the first conditioning chamber into the second conditioning chamber. The humidity regulating assembly 230 is located in the second conditioning chamber, for example, on the sixth fixed plate, and can humidify or dehumidify the air as needed to ensure that the relative humidity of the air meets the preset standard. The air enters here from the first conditioning chamber through the second air outlet 210, and the humidity regulating assembly 230 is responsible for humidifying or dehumidifying the air.

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

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

[0059] In some embodiments, the second conditioning chamber includes a first fence assembly 240 and a circulating fan 220. The first fence assembly 240 includes a plurality of fences, which are staggered in the second conditioning chamber. The fences are used to adjust the gas flow direction and extend the air flow channel to facilitate gas removal.

[0060] Specifically, the fence enables the air entering the second conditioning chamber to be evenly dispersed. When the air enters the first conditioning chamber through the first air outlet 110, the circulating fan 220 sucks it in and sends it to the second conditioning chamber. The staggered distribution of the fence forces the air to be evenly dispersed before entering the humidity conditioning assembly 230, avoiding airflow concentration at a certain point, ensuring that the air is evenly processed in the humidity conditioning assembly 230. The fence can also prevent the air from passing directly without being fully conditioned, avoiding airflow short-circuiting, and ensuring that each portion of the air is processed by the humidity conditioning assembly 230.

[0061] The fence extends the path of the airflow in the second conditioning chamber, increases the contact time between the air and the humidity conditioning assembly 230, ensures that the moisture in the air is more fully absorbed or released, and improves the efficiency and effect of humidity conditioning. By extending the airflow channel, the residence time of the air in the humidity conditioning assembly 230 is increased, making the humidity conditioning more precise.

[0062] The circulation fan 220 is connected to the first conditioning chamber and the second conditioning chamber, and is used to suck the air of the first conditioning chamber and send it into the humidity adjustment component 230 of the second conditioning chamber to ensure that the air is fully mixed and adjusted.

[0063] The air is drawn from the first conditioning chamber to the second conditioning chamber. Exemplarily, the air is sucked into the first conditioning chamber through the first air outlet 110, and the humidity sensor 120 detects the relative humidity of the air entering the first conditioning chamber. If the detected humidity is not within the preset range, the second air outlet 210 is opened to allow air to enter the second conditioning chamber, and the circulating fan 220 is started to suck the air from 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 adjustment assembly 230 humidifies 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. The third conditioning chamber is a processing area for humidity-conditioned air, and includes a third air port 310 and an air outlet 330. The third air port 310 can be arranged on the seventh fixed plate, between the second conditioning chamber and the third conditioning chamber, so that the humidity-conditioned air can flow into the third conditioning chamber. The air outlet 330 can be arranged on the tenth fixed plate, in the third conditioning chamber, and is the outlet for humidity-conditioned air to leave the humidity conditioning device.

[0065] In some embodiments, the first air outlet 110 and the second air outlet 210 are arranged in a first direction, and the third air outlet 310 is arranged in a second direction. Exemplarily, the first air outlet 110 and the second air outlet 210 are arranged on the left side, and the third air outlet 310 is arranged on the right side. The direction of the third air outlet 310 can be arranged on the same side as the humidity adjustment component 230. The third air outlet 310 is opposite to the direction of the air outlet 330.

[0066] In some embodiments, the third conditioning chamber also includes an odor sensor 320, which is disposed 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 outlet 310. The odor sensor 320 can monitor the odor in the air in real time to ensure the quality of the exhausted air.

[0067] The air flows from the second conditioning chamber to the third conditioning chamber. For example, the air processed by the humidity conditioning component 230 enters the third conditioning chamber through the third air outlet 310, and the concentration of odor molecules is detected by the odor sensor 320. If the concentration meets the preset range, the air is discharged from the air outlet 330 after passing through the second fence component 340. The fence can extend the path of the airflow in the third conditioning chamber and increase the residence time of the air in the third conditioning chamber, which helps the odor molecules in the air to fully contact with the odor sensor 320 and improve the accuracy of odor detection.

[0068] Based on the above-mentioned humidity regulating device, some embodiments of the present application also provide a refrigerator, including: a shell and a controller, wherein the above-mentioned humidity regulating device is arranged in the shell.

[0069] See also Figure 2 , the controller is configured as:

[0070] Acquire a first humidity detection result, where the first humidity detection result is a first humidity value of the first conditioned indoor air detected by the humidity sensor;

[0071] If the first humidity value is not within the preset humidity range, start the first adjustment mode, and send instructions to the circulation fan and the humidity adjustment component to control the circulation fan and the humidity adjustment component to start, the first adjustment mode is a mode of closing the first air outlet and the third air outlet and opening the second air outlet;

[0072] Acquire a second humidity detection result, where the second humidity detection result is a second humidity value of the air in the first conditioned room detected by the humidity sensor and conditioned by the humidity conditioning component;

[0073] If the second humidity value is within the preset humidity range, the second adjustment mode is started, and an instruction is sent to the humidity adjustment component to control the humidity adjustment component to close. The second adjustment mode is a mode of closing the first air outlet and opening the second and third air outlets.

[0074] The preset humidity range may 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 working and prepares to receive the detection result of the humidity sensor, that is, the humidity sensor set in the first detection chamber. The controller obtains the first humidity value of the air in the first conditioning chamber from the humidity sensor, and determines 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 adjustment mode. The first adjustment mode is to transport air from the first adjustment chamber to the second adjustment chamber to adjust the humidity value of the air through the humidity adjustment component.

[0076] During the adjustment process, the humidity sensor detects the humidity in real time, that is, the second humidity value. If the second humidity value is within the preset humidity range, the controller starts the second adjustment mode. The second adjustment mode is to transport air from the second adjustment chamber to the third adjustment chamber so as to be discharged through the air outlet.

[0077] By using humidity sensors and controllers in conjunction with a dynamic damper adjustment mode, high-precision humidity control can be achieved to ensure that the humidity inside the refrigerator is always within the preset range.

[0078] In some embodiments, at least a first chamber is disposed within the housing;

[0079] Before obtaining the first humidity detection result, the controller is further configured to:

[0080] In response to the refrigerator being powered on, the fourth adjustment mode is started, and a command is sent to the circulation fan to control the circulation fan to start. The first adjustment mode is a mode of closing the second air outlet and opening the first air outlet and the third air outlet.

[0081] In order to remove the gas in the humidity control device, the circulating fan is started, sucking in outside air from the first air outlet into the first conditioning chamber. Since the second air outlet is closed, the air cannot directly enter the second conditioning chamber from the first conditioning chamber. Therefore, the air circulates in the first conditioning chamber and does not enter the second conditioning chamber. The original gas in the second conditioning chamber enters the third conditioning chamber from the third air outlet and is then discharged from the air outlet. In this way, the original gas in the second conditioning chamber (which may contain odor, too high or too low humidity) can be discharged, ensuring that new air enters the system and prepares for subsequent humidity adjustment.

[0082] Through the fourth adjustment mode, the refrigerator can quickly discharge the original gas in the second adjustment chamber when powered on to improve the accuracy and effect of humidity control.

[0083] Refrigerators are used to store a variety of food ingredients at home. The ingredients may produce various odors, including the odor of the food ingredients themselves, the odor of refrigerator materials, the odor of microbial metabolism, etc. These odors are mixed together, which will cause the odor of the food ingredients in the refrigerator to cross-flavor, affecting the edible quality of the food ingredients. The odor removal methods in refrigerators can be divided into normal operation and intelligent operation. Normal operation is that the odor removal device in the refrigerator is turned on according to a certain inherent logic. The intelligent operation is that the refrigerator is equipped with an odor sensor and an odor removal device. When the odor sensor recognizes that the odor molecules have reached a certain concentration, the odor removal device is turned on to remove the odor molecules.

[0084] The normal operation mode can remove odors to a certain extent, but there are disadvantages, that is, the deodorizing device cannot determine whether the odor is completely removed, which may lead to incomplete odor removal. When the odor is strong, the deodorizing device cannot start purification immediately, resulting in a poor user experience. The intelligent operation mode uses the odor sensor to identify the odor concentration in the refrigerator in real time, and can intelligently control the operation of the deodorizing device according to the odor concentration. The odor sensor is based on the physical and chemical reaction between the sensitive material and the odor molecules, which causes the electrochemical signal of the material to change, and then determines the concentration of the odor molecules. However, the relative humidity of the space affects the physical and chemical reaction, resulting in large differences in the electrochemical signal at the same odor molecule concentration, resulting in low accuracy of the odor sensor.

[0085] In some embodiments, a deodorizing component is provided in the refrigerator. The deodorizing component is a device for removing odors in the refrigerator, and may be an activated carbon filter, a photocatalyst purifier, an ion generator, and the like.

[0086] In some embodiments, the humidity sensor is also used to detect the relative humidity of the environment near the odor sensor. The odor sensor is also used to detect the odor in the refrigerator. Based on the physicochemical reaction between the sensitive material and the odor molecules, an electrochemical signal is generated to determine the concentration of the odor molecules.

[0087] The controller is also configured to:

[0088] Acquire a relative humidity detection result, where the relative humidity detection result is 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 operating range, a command is sent to the humidity regulating device to control the humidity regulating device to start.

[0090] It can be understood that the location where the humidity sensor is set can be set to a relative humidity value within a preset range that can detect the odor sensor. Different humidity detection results and concentration detection results are all the results of detection by the humidity sensor and the odor sensor at different times.

[0091] By using a humidity sensor to detect the relative humidity near the odor sensor, the relative humidity in the area can be kept within the preset humidity operating range, thereby eliminating the effect of humidity on the electrochemical signal and improving the accuracy of the odor sensor. If the relative humidity exceeds the humidity operating range, the humidity is adjusted by automatically starting the humidity adjustment device to ensure that the detection results of the odor sensor are 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, obtaining a second concentration detection result, where the second concentration detection result is a second odor molecule concentration value in the housing detected by the odor sensor;

[0094] If the second odor molecule concentration value is greater than or equal to the second concentration threshold, an instruction is sent to the odor purification component to control the odor purification component to start.

[0095] When the relative humidity value is within the humidity working range, it indicates that the odor sensor is working under appropriate humidity conditions and the detection result is highly accurate. When the concentration of odor molecules is greater than or equal to the threshold concentration value, the deodorization module is started.

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

[0097] Obtaining a first concentration detection result, where the first concentration detection result is a first odor molecule concentration value of the third adjustment chamber detected by the odor sensor;

[0098] If the concentration value of the first odor molecule is greater than or equal to the first concentration threshold, the third adjustment mode is started, and an instruction is sent to the odor purification component to control the startup of the odor purification component. The third adjustment mode is a mode of opening the first air outlet, the second air outlet and the third air outlet.

[0099] If the concentration value of the first odor molecule is greater than or equal to the first concentration threshold, the controller starts the third adjustment mode, opens the first air outlet, the second air outlet and the third air outlet, so that the air can flow freely between the first adjustment chamber, the second adjustment chamber and the third adjustment chamber, and the deodorization component is started to remove the odor molecules in the third adjustment chamber. In the third adjustment mode, opening all air outlets allows the air to flow freely between the various adjustment chambers, thereby improving the deodorization efficiency.

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

[0101] Based on the above refrigerator, some embodiments of the present application also provide a humidity adjustment method, including:

[0102] Acquire a first humidity detection result, where the first humidity detection result is a first humidity value of the first conditioned indoor air detected by the humidity sensor;

[0103] If the first humidity value is not within the preset humidity range, start the first adjustment mode, and send instructions to the circulation fan and the humidity adjustment component to control the circulation fan and the humidity adjustment component to start, the first adjustment mode is a mode of closing the first air outlet and the third air outlet and opening the second air outlet;

[0104] Acquire a second humidity detection result, where the second humidity detection result is a second humidity value of the air in the first conditioned room detected by the humidity sensor and conditioned by the humidity conditioning component;

[0105] If the second humidity value is within the preset humidity range, the second adjustment mode is started, and an instruction is sent to the humidity adjustment component to control the humidity adjustment component to close. The second adjustment mode is a mode of closing the first air outlet 110 and opening the second air outlet and the third air outlet.

[0106] In some embodiments, the humidity adjustment method also includes: before obtaining the first humidity detection result, in response to the power of the refrigerator being turned on, starting the fourth adjustment mode, and sending instructions to the circulation fan to control the start of the circulation fan. The first adjustment mode is a mode of closing the second air outlet and opening the first air outlet and the third air outlet.

[0107] Based on the above refrigerator, see Figure 3Some embodiments of the present application also provide a refrigerator deodorizing method, comprising:

[0108] Acquire a relative humidity detection result, where the relative humidity detection result is a relative humidity value within 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, where the second concentration detection result is a second odor molecule concentration value in the housing detected by the odor sensor;

[0110] If the concentration value of the second odor molecule is greater than or equal to the second concentration threshold, an instruction is sent to the odor purification component to control the odor purification component to start.

[0111] The method also includes: if the relative humidity value is not within the humidity operating range, wherein the humidity operating range can be 40-70%, sending an instruction to the humidity regulating device to control the humidity regulating device to start, the humidity regulating device is the humidity regulating device provided in the above embodiment, and the control method of the humidity regulating device can be based on the above refrigerator embodiment.

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

[0113] The method adjusts the relative humidity of the working environment of the odor sensor to 40-70%, so that the odor sensor operates under suitable humidity, can accurately identify the odor concentration in the refrigerator environment, accurately control the operation of the odor removal device, and bring a good odor removal experience to the user.

[0114] Similar parts between the embodiments provided in this application can be referenced to each other. The specific implementation methods provided above are only a few examples under the general concept of this application and do not constitute a limitation on the protection scope of this application. For those skilled in the art, any other implementation methods expanded based on the scheme of this application without creative work belong to the protection scope of this application.
