[0046] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0047] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0048] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such products or devices.

[0049] With the improvement of living standards, refrigerators have become an indispensable household appliance in people's daily lives, and more and more types of food are stored in refrigerators. However, food will emit various odors, causing odors in the refrigerator. At present, the existing refrigerator odor purification methods mainly include: odor purification methods based on ozone, ultraviolet rays, ion sterilization and other technologies. However, if the refrigerator runs the above refrigerator odor purification method for a long time, ozone will be generated in the refrigerator. High concentrations of ozone will not only accelerate the aging of various plastic parts in the refrigerator, but also be harmful to human health.

[0050] Therefore, some existing implementations propose to purify the odor in the refrigerator by slowly releasing active oxidizing substances instead of ozone. This existing implementation does not generate ozone, avoiding the problem that ozone accelerates the aging of various plastic parts in the refrigerator and is harmful to human health. However, the existing method of slowly releasing the above-mentioned oxidizing substances is to directly place the oxidizing substances in the refrigerator and allow them to volatilize and release on their own, which has the problem of poor flexibility of slow release and poor accuracy of odor purification.

[0051] Taking into account the above-mentioned problems existing in the existing refrigerator odor purification methods, the present application proposes a method for controlling the release rate of sustained-release odor-purifying substances based on the concentration of the odor-purifying substances, so as to improve the flexibility of the sustained-release odor-purifying substances and thereby improve the accuracy of odor purification.

[0052] first, Figure 1This is a schematic diagram of the structure of a refrigerator provided in this application. Figure 1 As shown, the refrigerator may include: a cabinet, a deodorizing device, and a control device. The deodorizing device may include: a heating module, a slow-release deodorizing module, and a slow-release gas detection module.

[0053] The deodorizing device can be arranged in the refrigerator. The heating module and the slow-release gas detection module can be connected to the control device. The heating module can be connected to the slow-release deodorizing module.

[0054] It should be understood that the present application does not limit the number of boxes included in the refrigerator, the number of deodorizing devices included in the boxes, and the number of heating modules and slow-release deodorizing modules included in the deodorizing devices. Optionally, the above-mentioned boxes can be the refrigerator compartment and / or freezer compartment of the refrigerator. In addition, the present application does not limit the location of the deodorizing device in the box. It should be understood that the present application does not limit the connection method between the heating module and the slow-release gas detection module and the control device.

[0055] Exemplarily, the heating module may be any existing component such as a heating wire, the heating temperature of which can be controlled by a control device, and the present application does not limit this.

[0056] The above-mentioned slow-release odor-purifying module can be used to release a target gas that can purify the odor in the box. It should be understood that the present application does not limit the type of the target gas. Optionally, the target gas can be, for example, any existing active oxidizing substance, such as herbal extracts (such as eucalyptus oil, lemon oil), etc. In some embodiments, the target gas that can purify the odor in the box can also be called a functional component of the slow-release odor-purifying module.

[0057] The above slow-release gas detection module can be used to detect the concentration of the target gas. Optionally, the slow-release gas detection module can be, for example, any existing sensor capable of detecting the concentration of the target gas, which will not be described in detail here.

[0058] The control device may be, for example, a microcontroller unit (MCU) or any other device having a processing function.

[0059] It should be understood that Figure 1 The structure of the refrigerator is merely described by taking part of the structure related to the present application as an example, and the present application does not limit whether the refrigerator includes other components.

[0060] The executor of the odor purification method provided in the present application may be the control device of the refrigerator, or the refrigerator itself, and the present application does not limit this.

[0061] Based on Figure 1 The refrigerator shown in the figure, the execution subject of the odor purification method provided by the present application is a refrigerator control device as an example, and the technical solution of the present application is described in detail in combination with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0062] Figure 2 The following is a schematic diagram of a method for odor purification provided in this application. Figure 2 As shown, the method may include the following steps:

[0063] S101. Obtain the concentration of the target gas.

[0064] Optionally, the concentration of the target gas can be used to characterize the residual amount of the target gas in the slow-release odor-free module. For example, the concentration of the target gas can be positively correlated with the residual amount of the target gas in the slow-release odor-free module. In other words, the more residual amount of the target gas in the slow-release odor-free module, the greater the concentration of the target gas. The less residual amount of the target gas in the slow-release odor-free module, the smaller the concentration of the target gas.

[0065] Optionally, the control device can, for example, obtain the concentration of the target gas detected by the slow-release gas detection module. For example, the slow-release gas detection module can periodically collect the concentration of the target gas and send the collected concentration of the target gas to the control device. Correspondingly, the control device can receive the concentration of the target gas. Alternatively, the control device can also send a gas concentration detection instruction to the slow-release gas detection module, so that the slow-release gas detection module responds to the instruction and detects the concentration of the target gas.

[0066] S102. According to the concentration of the target gas, the heating module is controlled to heat the slow-release odor-removing module.

[0067] Among them, the release rate of the target gas released by the slow-release odor-free module can be related to the temperature of the heating module. For example, the release rate of the target gas released by the slow-release odor-free module can be positively correlated with the temperature of the heating module. In other words, the higher the temperature of the heating module, the faster the release rate of the target gas released by the slow-release odor-free module can be. The lower the temperature of the heating module, the slower the release rate of the target gas released by the slow-release odor-free module can be.

[0068] As mentioned above, the heating module can be connected to the slow-release odor-purifying module, so by adjusting the temperature of the heating module, the temperature at which the heating module heats the slow-release odor-purifying module can be controlled. Optionally, the control device can control the working power of the heating module based on the concentration of the target gas, thereby controlling the temperature of the heating module and further controlling the release rate of the target gas released by the slow-release odor-purifying module. The greater the working power of the heating module, the higher the temperature of the heating module can be; the smaller the working power of the heating module, the lower the temperature of the heating module can be.

[0069] Exemplarily, the higher the concentration of the above target gas, the more residual target gas there is in the slow-release odor-purifying module, and the control device can control the temperature of the heating module to be lower, so as to reduce the release rate of the target gas released by the slow-release odor-purifying module, so as to save the amount of target gas used in the odor-purifying process. The lower the concentration of the above target gas, the less residual target gas there is in the slow-release odor-purifying module, and the control device can control the temperature of the heating module to be higher, so as to increase the release rate of the target gas released by the slow-release odor-purifying module, so as to ensure that a sufficient amount of target gas can be released to achieve the odor-purifying effect.

[0070] In this embodiment, by providing a heating module connected to the slow-release odor-purifying module in the odor-purifying device, the heating module can be controlled to heat the slow-release odor-purifying module, thereby adjusting the release rate of the target gas for odor-purifying released by the slow-release odor-purifying module, thereby improving the flexibility of the target gas release, and thus improving the flexibility of odor-purifying the refrigerator. Through the concentration of the target gas, the heating module can be controlled to heat the slow-release odor-purifying module, so that the release rate of the target gas is related to the concentration of the target gas, thereby achieving the targeted release of the target gas, improving the accuracy of odor purification, and reducing the waste of the target gas while ensuring that the odor-purifying effect can be achieved.

[0071] As a possible implementation method, the control device may also determine the odor concentration in the box before controlling the heating module to heat the slow-release odor-purifying module according to the concentration of the target gas.

[0072] Figure 3 This is a schematic diagram of another refrigerator structure provided by this application. Figure 3 As shown, illustratively, the refrigerator may further include an odor detection device, which may be disposed in the refrigerator body. The control device may be connected to the odor detection device. The odor detection device may be used to detect the odor concentration in the body. In other words, the control device may collect the odor concentration in the body through the odor detection device. illustratively, the odor detection device may be any existing gas sensor capable of detecting the odor concentration in the refrigerator, and the present application does not limit this.

[0073] Then, the control device controls the heating module to heat the slow-release odor-purifying module based on the aforementioned odor concentration and the concentration of the target gas.

[0074] For example, the control device may determine the relationship between the concentration of the target gas and the first preset concentration and the second preset concentration. The first preset concentration and the second preset concentration may be pre-stored in the control device, for example. The first preset concentration may be less than the second preset concentration.

[0075] If the concentration of the target gas is greater than or equal to the first preset concentration and less than the second preset concentration, it means that part of the active ingredients of the sustained-release odor-purifying module have been consumed, that is, part of the target gas has been consumed, so the odor-purifying effect will be reduced compared to normal circumstances. Therefore, the control device can determine the first preset power of the heating module according to the odor concentration in the box, and control the heating module to heat the sustained-release odor-purifying module according to the first preset power. Among them, the first preset power of the heating module can be positively correlated with the odor concentration in the box. In other words, the greater the odor concentration in the box, the greater the first preset power of the heating module can be. The smaller the odor concentration in the box, the smaller the first preset power of the heating module can be.

[0076] If the concentration of the target gas is greater than or equal to the second preset concentration, it means that the function of the slow-release odor-purifying module is normal, that is, the residual amount of the target gas is sufficient. Then the control device can determine the second preset power of the heating module according to the odor concentration in the box, and control the heating module to heat the slow-release odor-purifying module according to the second preset power. Among them, the second preset power of the heating module can be positively correlated with the odor concentration in the box. In other words, the greater the odor concentration in the box, the greater the second preset power of the heating module can be. The smaller the odor concentration in the box, the smaller the second preset power of the heating module can be.

[0077] Among them, when the odor concentration in the above-mentioned box is the same, the above-mentioned second preset power is less than the first preset power. The smaller the power of the heating module, the lower the temperature of the heating module, and the lower the release rate of the target gas when the slow-release odor-purifying module is heated by the heating module. Therefore, through the above method, when the odor concentration in the box is the same, if the concentration of the target gas is large, the release rate of the target gas is lower when the slow-release odor-purifying module is heated by the heating module. If the concentration of the target gas is small, the release rate of the target gas is higher when the slow-release odor-purifying module is heated by the heating module.

[0078] When the control device determines the first preset power or the second preset power of the heating module according to the odor concentration in the box, for example, the control device can determine the first preset power or the second preset power according to the odor concentration in the box and the mapping relationship between the odor concentration and the power. It should be understood that the mapping relationship between the odor concentration and the power used to determine the first preset power is different from the mapping relationship between the odor concentration and the power used to determine the second preset power.

[0079] Exemplarily, taking the classification of the odor concentration in the refrigerator into different levels (wherein the odor concentration of level A is less than the odor concentration of level B, and the odor concentration of level B is less than the odor concentration of level C) as an example, the control device may determine the second preset power or the first preset power of the heating module through the following Table 1:

[0080] Table 1

[0081]

[0082] Taking the mapping relationship shown in Table 1 as an example, the second preset power 1 is less than the second preset power 2, and the second preset power 2 is less than the second preset power 3. The first preset power 1 is less than the first preset power 2, and the first preset power 2 is less than the first preset power 3. At the same level of odor concentration, the second preset power 1 is less than the first preset power 1; the second preset power 2 is less than the first preset power 2; the second preset power 3 is less than the first preset power 3. Taking Table 1 as an example, illustratively, if the concentration of the target gas is greater than or equal to the second preset concentration, and the odor concentration in the box is a B-level odor concentration, the control device can determine that the power of the heating module is the second preset power 2.

[0083] In some embodiments, if the concentration of the target gas is less than the first preset concentration, it means that the target gas in the slow-release deodorizing module has been consumed and needs to be replaced, and the control device can output a prompt message for prompting the user to replace the deodorizing device. Through the above method, the user can know in time that the target gas is consumed, and then can replace the deodorizing device in time, ensuring the timeliness of deodorizing the refrigerator, and further improving the user experience.

[0084] Optionally, the control device may display the above prompt information on a display device of the refrigerator, for example. Alternatively, the refrigerator may further include an indicator light for indicating that the target gas in the slow-release deodorizing module has been consumed. The control device may output the above prompt information by lighting the indicator light.

[0085] Furthermore, in some embodiments, if the user still has not replaced the odor purification device or replaced the slow-release odor purification module after the refrigerator sends the above-mentioned prompt message (for example, the control device can determine that the odor purification device has not been replaced or the slow-release odor purification module has not been replaced when it determines that the concentration of the target gas is always low), then the control device may no longer control the operation of the odor purification device after the target time interval ends until the user replaces the odor purification device, and then execute the odor purification method provided in any embodiment of the present application.

[0086] Figure 4 This is a schematic diagram of another refrigerator structure provided by this application. Figure 4 As shown, as a possible implementation, the above-mentioned deodorizing device may further include: a fan. When the fan is working, it can be used to accelerate the flow of the target gas. The fan can be connected to the control device. It should be understood that the present application does not limit the number of fans included in the deodorizing device and the specific setting position.

[0087] In this implementation, the control device may also first determine the odor concentration in the box, and then control the rotation speed of the fan according to the odor concentration in the box.

[0088] Optionally, the control device determines the odor concentration in the above-mentioned box body in a manner that refers to the method for obtaining the odor concentration described in the above-mentioned embodiment, and the present application will not repeat it here.

[0089] Optionally, the control device can determine the speed of the fan according to the odor concentration in the box, and the mapping relationship between the odor level to which the odor concentration belongs and the fan speed, and control the fan to run at the speed. Optionally, the speed of the fan can be positively correlated with the odor concentration in the box. In other words, the greater the odor concentration in the box, the greater the speed of the fan, so as to make the target gas flow as quickly as possible and reduce the odor in the box as quickly as possible. The smaller the odor concentration in the box, the smaller the speed of the fan, so as to save energy.

[0090] The flow rate of the target gas can be controlled by the above-mentioned fan. The speed of the fan can be controlled by the odor concentration in the above-mentioned box, so that the speed of the fan is related to the odor concentration in the box, which improves the accuracy of controlling the speed of the fan and further improves the accuracy of odor removal.

[0091] In this implementation, the timing of the control device executing the aforementioned step S101 to obtain the concentration of the target gas is described in detail below:

[0092] In some embodiments, the control device can, for example, respond to an instruction to stop the fan and control the heating module to heat the slow-release odor-removing module according to a third preset power. After the first preset time, the control device can control the heating module to stop working and obtain the concentration of the target gas through the slow-release gas detection module.

[0093] The third preset power and the first preset duration may be pre-stored in the control device. The instruction to stop the fan may be generated by the control device when the fan speed is zero, for example.

[0094] By heating the slow-release odor-removing module and controlling the heating module to stop working after a first preset time, the slow-release odor-removing module can release a portion of the target gas, so that the control device can detect the concentration of the target gas. By performing the operation of obtaining the concentration of the target gas when the fan stops working, the possibility of the fan blowing the target gas away is avoided, the accuracy of detecting the concentration of the target gas is improved, and the accuracy of the subsequent control of the release rate of the target gas based on the concentration of the target gas is improved, thereby improving the accuracy of odor removal.

[0095] In some embodiments, the control device can also control the speed of the fan according to the odor concentration in the box, and control the heating module to heat the slow-release odor-purifying module according to the concentration of the target gas, and then determine whether the odor concentration in the box is reduced to the target odor concentration value.

[0096] For example, if the odor concentration in the box is not reduced to the target odor concentration value within the second preset time after the fan speed is controlled according to the odor concentration in the box, and the heating module is controlled to heat the slow-release deodorization module according to the concentration of the target gas, the control device can also control the fan to stop working and control the heating module to stop heating, so as to reduce the consumption of the target gas and save energy.

[0097] Then, after the third preset time period, the control device can again control the speed of the fan according to the odor concentration in the box, and control the heating module to heat the slow-release odor-purifying module according to the concentration of the target gas.

[0098] Among them, the second preset time length, the third preset time length and the target odor concentration value may be pre-stored in the control device.

[0099] Through the above method, the rate at which the target gas is released by the slow-release odor-purifying module can be intermittently accelerated, thereby ensuring the purification of odors in the refrigerator and reducing the consumption of the target gas.

[0100] For example, Figure 5 This is a schematic diagram of the structure of another refrigerator provided in this application. Figure 5 As shown, exemplary, the odor detection device can be as follows Figure 5 The odor sensor shown in the figure, exemplarily, the above-mentioned odor removal device includes two heating wires, and the two heating wires are respectively connected to a slow-release odor removal module. The odor removal device of the refrigerator may also include a fan, and air doors arranged on both sides of the odor removal device. Exemplarily, Figure 6 The following is a schematic diagram of the installation location of a deodorizing device. Figure 6 As shown, as an example, the deodorizing device can be installed in the refrigerator compartment of a refrigerator. Figure 7 The figure is a schematic diagram of the structure of a deodorizing device. Figure 7 As shown, the deodorizing device may further include a mounting buckle. The deodorizing device may be fixed in the refrigerator body by the mounting buckle. Figure 8 FIG. 1 is a schematic diagram of the structure of another deodorizing device. Figure 8 As shown, exemplarily, the slow-release odor-purifying module of the odor-purifying device can be a porous slow-release fast to release the target gas.

[0101] Based on Figure 5-Figure 8 The odor purification device shown in the figure is used to exemplify the odor purification method provided by the present application:

[0102] Based on offline research on the response of sensors to the odors of different foods and human sensory research, the odor can be divided into three different odor levels according to the output signal of the sensor, such as 1~X1 is level A; X1~X2 is level B; X2~X3 is level C, among which level A is basically odorless, level B is slight odor, and level C is obvious odor.

[0103] The odor sensor can monitor the odor in the refrigerator in real time and control the operation of the deodorizing device according to the different odor levels. The main body of the deodorizing device can be a closed cavity, including two front and rear air doors, and the cavity contains a fan, a slow-release catalyst block, a catalyst block slot, a heating wire and a slow-release odor sensor.

[0104] When the control device senses that the odor level in the refrigerator is Class A through the odor sensor, the odor purification device is controlled not to operate. At this time, the system (that is, the control device) can start timing. When the accumulated time t≥T1, the odor purification device is controlled to operate: the heating wire of the odor purification device starts to operate with a power of W1 to heat the slow-release odor purification module (because the refrigerator compartment is in a low temperature environment for a long time, the slow-release rate will be reduced. In order to ensure the odor purification effect, it is heated to accelerate the slow release). At the same time, the damper is opened and the fan runs at a speed of R1 to quickly diffuse the slow-release odor purification substance into the refrigerator compartment for odor purification. After the accumulated operation time of T1-1, the damper is closed, the fan stops running, and the heating wire stops running. During this period, the odor sensor still works in real time to monitor the odor level in the refrigerator. When the odor level has been at Class A, it will run again according to the above procedure after an interval of T0 time.

[0105] When the odor sensor senses that the odor level in the refrigerator is B, the odor removal device is controlled to operate: the odor removal device heating wire starts to operate, and the power is W2 at this time, heating the slow-release odor removal module (W1<W2, because the odor level is at B level, the odor concentration is greater, so more active ingredients need to be slowly released for odor removal, and the power of the heating wire needs to be increased); at the same time, the damper is opened, and the fan runs at R2 speed (R1<R2), accelerating the circulation, and quickly diffusing the slow-release odor removal substances to the refrigerator for odor removal, so as to improve the odor removal efficiency. During this period, the odor sensor monitors the odor level in the refrigerator in real time. When the odor level is always at B level, the damper is closed, the fan stops running, and the heating wire stops running after the above procedure has accumulated T1-2 time. If the odor sensor senses that the odor level drops to A level during this period, the system controls the door to close, the fan stops running, and the heating wire stops running; start timing and if the odor sensor senses that the odor level is still A during this period, it will run according to the above A level procedure after an interval of T0 time. If the odor sensor senses that the odor level rises to C level during this period, it will operate according to that level. If the odor sensor senses B level during T1-2 time, the odor removal device will stop operating after T1-2 time, and after T0 time, the odor removal device will be controlled to operate according to the odor level determined by the sensor.

[0106] When the odor sensor senses that the odor level in the refrigerator is C, the odor removal device is controlled to operate: the odor removal device heating wire starts to operate, and the power is W3 at this time, heating the slow-release odor removal module (W1<W2<W3); at the same time, the damper is opened, and the fan runs at R3 speed (R1<R2<R3), accelerating the circulation, and quickly diffusing the slow-release odor removal substances to the refrigerator for odor removal, so as to improve the odor removal efficiency. During this period, the odor sensor monitors the odor level in the refrigerator in real time. When the odor level is always at C level, the damper is closed, the fan stops running, and the heating wire stops running after T1-3 cumulative times according to the above procedure; if the odor sensor senses that the odor level is B during this period, the odor removal device is controlled to operate according to the B-level procedure. If during the T1-2 time period, the odor sensor always senses that it is B level, and the odor removal device runs for T1-2 time, the control device stops running, and after an interval of T0 time, the odor removal device is controlled to operate according to the odor level judged by the sensor.

[0107] The three processes corresponding to levels A, B, and C share the same running time timer. When there is an odor level switch, as long as the accumulated running time is greater than or equal to the running time requirement of the current level, T0 will be immediately entered for re-timing.

[0108] Since the slow-release odor-removing module is consumable, different slow-release speeds are used for different odor concentrations to increase the service life of the slow-release odor-removing module. Since the slow-release odor-removing module is a consumable, when the concentration of the active ingredient in the load decreases or is consumed, the odor-removing effect will decrease or be lost. At this time, the user can be reminded to replace the odor-removing module. When the concentration of the active ingredient decreases over time, the odor-removing effect per unit time will significantly decrease. Therefore, the following control can be used to remove the odor as soon as it is sensed.

[0109] When the odor removal device is stopped, the damper is closed and the system evaluates the life or remaining amount of the slow-release block. The heating wire runs at W0 power to promote the release of slow-release gas into the device. After t time, the heating wire stops working; the slow-release gas sensor starts working to monitor the concentration of slow-release gas in the device:

[0110] When the sensed slow-release gas concentration is Y2≤Y<Y3, it indicates that the slow-release module functions normally and the system maintains the above working mode.

[0111] When the concentration of the slow-release gas is perceived to be Y1≤Y<Y2, it indicates that part of the active ingredients in the slow-release module have been consumed, so the deodorizing effect will be lower than before. In this case, when the deodorizing device works again, the following control is performed: when the odor sensor perceives the odor level as A, the operation program of the deodorizing device remains unchanged; when the odor sensor perceives the odor level as B, the heating wire is increased from the original W2 power to W3 when the deodorizing device is running, so that the heating wire can release more active ingredients in the slow-release module per unit time at a higher power, so as to make up for the problem of reduced slow-release amount per unit time caused by the reduction in the total content of active ingredients in the module, and maintain the deodorizing effect; similarly, when the odor sensor perceives the odor level as C, the heating wire is increased from the original W3 power to W4 when the deodorizing device is running, where W4>W3.

[0112] When the sensed slow-release gas concentration is 0≤Y<Y1, it indicates that the slow-release module has been exhausted and needs to be replaced. At this time, the system will remind the user to replace it. If the user still does not replace it after the reminder, the system will no longer control the operation of the deodorization device after the T0 time interval until it is replaced. At this time, it will be controlled according to the odor level value sensed by the odor sensor.

[0113] In this embodiment, by installing a gas sensor and a slow-release deodorization module in the refrigerator, the gas sensor is used to monitor the odor in the refrigerator in real time. According to the different concentrations of odor in the refrigerator and the concentration of the target gas, the slow-release rate of the functional components of the slow-release deodorization module is controlled to achieve intelligent deodorization, which can improve the accuracy of deodorization and enhance the user experience. According to the extent to which the gas sensor is affected by the odor, the slow-release rate of the functional components of the slow-release module is controlled in a timely manner. Compared with the existing ion and ozone deodorization technologies, odor purification without ozone risk is achieved, and the installation structure is simple and can be replaced at any time. It is long-lasting and effective, further enhancing the user experience.
