[0037] In order to understand the features and technical content of the embodiments of the present application in more detail, the implementation of the embodiments of the present application will be described in detail below with reference to the accompanying drawings. The accompanying drawings are only for reference and explanation, and are not used to limit the embodiments of the present application.

[0038] The embodiments of the present application provide a sterilization control method to solve the problem of low air sterilization efficiency of existing household electrical appliances. This method is applied to household electrical appliances. Exemplarily, as Figure 1 shown, the household electrical appliance 10 may include a sterilization device 11 and a humidification device 12. The sterilization device 11 is arranged in the air outlet duct of the household electrical appliance 10, and the humidification device 12 is used to adjust the humidity in the sterilization channel of the sterilization device 11.

[0039] Figure 2 It is the first flow schematic diagram of the sterilization control method in the embodiments of the present application. As Figure 2 shown, this method may specifically include:

[0040] Step 201: Obtain the first sterilization environment humidity in the sterilization channel;

[0041] Here, the first sterilization environment humidity is collected by a humidity sensor arranged in the sterilization channel. The first environment humidity can be understood as the current humidity in the sterilization channel.

[0042] Step 202: Determine the first atomization rate of the humidification device based on the first sterilization environment humidity and a preset corresponding relationship; wherein, the corresponding relationship is used to represent the corresponding relationship between the sterilization environment humidity and the atomization rate;

[0043] Exemplarily, in some embodiments, the greater the sterilization environment humidity in the corresponding relationship, the smaller the atomization rate of the humidification device.

[0044] It should be noted that within a certain humidity range, the greater the sterilization environment humidity, the smaller the demand for the humidification device to adjust the humidity, that is, the greater the atomization rate of the sterilization device; the smaller the sterilization environment humidity, the greater the demand for the humidification device to adjust the humidity, that is, the smaller the atomization rate of the sterilization device.

[0045] In the embodiments of the present application, the corresponding relationship is used to characterize the corresponding relationship between the humidity of the sterilization environment and the atomization rate. The corresponding relationship can be embodied in the form of a calculation formula, or a corresponding relationship table formed on the basis of the calculation formula, and the corresponding relationship table is stored and searched. That is, the atomization rate corresponding to the first sterilization environment humidity can be determined by calculation, or the atomization rate corresponding to the first sterilization environment humidity can be found by looking up the table.

[0046] Correspondingly, the corresponding relationship includes: converting the first sterilization environment humidity based on a preset first conversion formula to obtain a third atomization rate; summing the third atomization rate and the default atomization rate of the humidifying device to obtain a first atomization rate.

[0047] The first conversion formula includes: a first constant minus the product of the first sterilization environment humidity and a second constant.

[0048] Exemplarily, the calculation formula of the corresponding relationship is: y = C0 + (C1 - x / C2), where C0 is the default atomization rate of the humidifying device, C1 is the first constant, 1 / C2 is the second constant, x is the first sterilization environment humidity, and y is the first atomization rate.

[0049] Exemplarily, in some embodiments, the corresponding relationship is also used to characterize the corresponding relationship between the power of the ultraviolet lamp in the sterilization channel and the atomization rate, and the greater the power of the ultraviolet lamp, the greater the atomization rate of the humidifying device.

[0050] It should be noted that the principle of the ultraviolet lamp irradiating the photocatalyst filter screen for sterilization is that the ultraviolet lamp irradiates the photocatalyst to form electron-hole pairs, and the electron-hole pairs act with surrounding water molecules and oxygen molecules to generate highly oxidizing hydroxyl radicals and superoxide ion radicals, thereby sterilizing. Within a certain power range, the greater the power of the ultraviolet lamp, the greater the irradiation intensity on the photocatalyst filter screen, and the higher the requirement for the environmental humidity. Therefore, when the power of the ultraviolet lamp increases, the atomization rate of the humidifying device needs to be increased to ensure that the sterilization environment humidity is maintained within the optimal humidity range.

[0051] Correspondingly, the corresponding relationship includes: converting the first sterilization environment humidity based on a preset first conversion formula to obtain a third atomization rate; determining a weight coefficient of the third atomization rate based on the power of the ultraviolet lamp; performing a weighted sum of the third atomization rate, the weight coefficient, and the default atomization rate of the humidifying device to obtain a first atomization rate.

[0052] Exemplarily, the calculation formula of the corresponding relationship is: y = C0 + a(C1 - x / C2), where C0 is the default atomization rate of the humidifying device, C1 is the first constant, 1 / C2 is the second constant, a is the weight coefficient, x is the first sterilization environment humidity, and y is the first atomization rate.

[0053] The magnitude of a is affected by the power of the ultraviolet lamp. The greater the power of the ultraviolet lamp, the greater a is. For example, the power of the ultraviolet lamp and a exhibit a linear relationship or a non-linear exponential relationship. The value range of a can be from 0.01 to 0.1, and the wavelength of the ultraviolet lamp can be 185 nm or 254 nm.

[0054] Exemplarily, in some embodiments, the corresponding relationship is also used to characterize the corresponding relationship between the wind speed and the atomization rate in the sterilization channel, and the greater the wind speed in the sterilization channel, the greater the atomization rate of the humidifying device.

[0055] It should be noted that the greater the wind speed in the sterilization channel indicates that the air passes through the sterilization channel faster, and the humidity of the sterilization environment is affected by the wind speed and decreases relatively quickly. To improve the sterilization efficiency, the atomization rate of the humidifying device should be increased when the wind speed is high. The greater the wind speed in the sterilization channel indicates that the air passes through the sterilization channel slower, and the humidity of the sterilization environment is affected by the wind speed and decreases relatively slowly or even has no effect. To improve the sterilization efficiency, the atomization rate of the humidifying device should be decreased or even the humidifying device should be turned off when the wind speed is low. This can avoid the formation of water droplets in the sterilization channel and affect the sterilization effect.

[0056] Correspondingly, the corresponding relationship includes: converting the first sterilization environment humidity based on a preset first conversion formula to obtain a third atomization rate; determining a weight coefficient of the third atomization rate based on the wind speed in the sterilization channel; and performing a weighted sum of the third atomization rate, the weight coefficient, and the default atomization rate of the humidifying device to obtain a first atomization rate.

[0057] Exemplarily, the calculation formula of the corresponding relationship is: y = C0 + b(C1 - x / C2), where C0 is the default atomization rate of the humidifying device, C1 is a first constant, 1 / C2 is a second constant, b is the weight coefficient, x is the first sterilization environment humidity, and y is the first atomization rate.

[0058] The magnitude of b is affected by the wind speed in the sterilization channel. The greater the wind speed, the greater b is. For example, the wind speed and b exhibit a linear relationship or a non-linear exponential relationship.

[0059] Step 203: When the first atomization rate is inconsistent with the current second atomization rate of the humidifying device, control the humidifying device to perform a humidifying operation at the first atomization rate to adjust the sterilization environment humidity in the sterilization channel.

[0060] Here, the first atomization rate is determined according to the first sterilization environment humidity. When the first atomization rate is 0, it indicates that the control of the humidifying device stops the humidifying operation. The second atomization rate is the current atomization rate of the humidifying device. When the second atomization rate is 0, it indicates that the humidifying device is in the off state.

[0061] The inconsistency between the first atomization rate and the second atomization rate indicates that the atomization rate of the humidifying device needs to be adjusted according to the first atomization rate.

[0062] The method further includes: when the first atomization rate is the same as the second atomization rate, controlling the humidifying device to continue the humidifying operation at the second atomization rate.

[0063] Exemplarily, Figure 3 FIG. 142 is a first structural schematic diagram of the sterilizing device and the humidifying device in the embodiment of the present application. As Figure 3 shown, the sterilizing device may include: a photocatalyst filter screen 32, an ultraviolet lamp 33, a driving power supply 34, and a control circuit 35. The sterilizing device is located in the air outlet duct 31 of the household electrical appliance. The nozzle of the humidifying device 12 is located in the sterilizing channel, and atomized water vapor is sprayed into the sterilizing channel to adjust the humidity in the sterilizing channel.

[0064] Exemplarily, Figure 4 FIG. 143 is a second structural schematic diagram of the sterilizing device and the humidifying device in the embodiment of the present application. As Figure 4 shown, the nozzle of the humidifying device 12 may also be located outside the sterilizing channel but point to the sterilizing channel to ensure that the atomized water vapor can be blown into the sterilizing channel.

[0065] By adopting the above technical solution, according to the humidity of the sterilizing environment in the sterilizing channel, the atomization rate of the humidifying device is adjusted, so that the humidity of the sterilizing environment in the sterilizing channel is maintained within the optimal humidity range, so that during the sterilization process of the sterilizing device, the number of sterilizing factors generated is large and the survival time is long, and the amount of ozone generated is small, maintaining a high sterilization efficiency.

[0066] In order to better reflect the purpose of the present application, on the basis of the above embodiments of the present application, further examples are given. As Figure 5 shown, the method specifically includes:

[0067] Step 501: Obtain the first sterilizing environment humidity in the sterilizing channel;

[0068] Step 502: Determine whether the first sterilizing environment humidity is less than a second humidity threshold. If so, execute Step 503; if not, execute Step 505;

[0069] Here, the second humidity threshold is less than the first humidity threshold, and the first humidity threshold and the second humidity threshold are the upper limit value and the lower limit value of the optimal humidity range. Within the optimal humidity range, during the sterilization process of the sterilizing device, the number of sterilizing factors generated is large and the survival time is long, and the amount of ozone generated is small, maintaining a high sterilization efficiency.

[0070] Step 503: Based on the first sterilizing environment humidity and a preset corresponding relationship, determine the first atomization rate of the humidifying device; wherein, the corresponding relationship is used to represent the corresponding relationship between the sterilizing environment humidity and the atomization rate;

[0071] Exemplarily, in some embodiments, the greater the humidity of the sterilization environment in the corresponding relationship, the smaller the atomization rate of the humidifying device.

[0072] Correspondingly, the corresponding relationship includes: converting the first sterilization environment humidity based on a preset first conversion formula to obtain a third atomization rate; summing the third atomization rate and the default atomization rate of the humidifying device to obtain a first atomization rate.

[0073] Exemplarily, the calculation formula of the corresponding relationship is: y = C0 + (C1 - x / C2), where C0 is the default atomization rate of the humidifying device, C1 is the first constant, 1 / C2 is the second constant, x is the first sterilization environment humidity, and y is the first atomization rate.

[0074] Exemplarily, in some embodiments, the corresponding relationship is also used to characterize the corresponding relationship between the power of the ultraviolet lamp in the sterilization channel and the atomization rate, and the greater the power of the ultraviolet lamp, the greater the atomization rate of the humidifying device.

[0075] Correspondingly, the corresponding relationship includes: converting the first sterilization environment humidity based on a preset first conversion formula to obtain a third atomization rate; determining the weight coefficient of the third atomization rate based on the power of the ultraviolet lamp; performing a weighted sum of the third atomization rate, the weight coefficient, and the default atomization rate of the humidifying device to obtain a first atomization rate.

[0076] Exemplarily, the calculation formula of the corresponding relationship is: y = C0 + a(C1 - x / C2), where C0 is the default atomization rate of the humidifying device, C1 is the first constant, 1 / C2 is the second constant, a is the weight coefficient, x is the first sterilization environment humidity, and y is the first atomization rate.

[0077] Exemplarily, in some embodiments, the corresponding relationship is also used to characterize the corresponding relationship between the wind speed in the sterilization channel and the atomization rate, and the greater the wind speed in the sterilization channel, the greater the atomization rate of the humidifying device.

[0078] Correspondingly, the corresponding relationship includes: converting the first sterilization environment humidity based on a preset first conversion formula to obtain a third atomization rate; determining the weight coefficient of the third atomization rate based on the wind speed in the sterilization channel; performing a weighted sum of the third atomization rate, the weight coefficient, and the default atomization rate of the humidifying device to obtain a first atomization rate.

[0079] Exemplarily, the calculation formula of the corresponding relationship is: y = C0 + b(C1 - x / C2), where C0 is the default atomization rate of the humidifying device, C1 is the first constant, 1 / C2 is the second constant, b is the weight coefficient, x is the first sterilization environment humidity, and y is the first atomization rate.

[0080] Step 504: When the first atomization rate is inconsistent with the current second atomization rate of the humidifying device, control the humidifying device to perform the humidifying operation at the first atomization rate to adjust the humidity of the sterilization environment in the sterilization channel;

[0081] Here, the first atomization rate is determined according to the first sterilization environment humidity. When the first atomization rate is 0, it indicates that the control humidifying device stops the humidifying operation. The second atomization rate is the current atomization rate of the humidifying device. When the second atomization rate is 0, it indicates that the humidifying device is in the closed state.

[0082] The inconsistency between the first atomization rate and the second atomization rate indicates that the atomization rate of the humidifying device needs to be adjusted according to the first atomization rate.

[0083] This method further includes: when the first atomization rate and the second atomization rate are consistent, control the humidifying device to continue to perform the humidifying operation at the second atomization rate.

[0084] Step 505: Determine whether the first sterilization environment humidity is greater than the first humidity threshold. If not, execute Step 506; if so, execute Step 507;

[0085] Step 506: Control the humidifying device to continue to perform the humidifying operation at the second atomization rate;

[0086] Step 507: Control the humidifying device to stop performing the humidifying operation.

[0087] Adopting the above technical solution, according to the humidity of the sterilization environment in the sterilization channel, the atomization rate of the humidifying device is adjusted to keep the humidity of the sterilization environment in the sterilization channel within the optimal humidity range. Thus, during the sterilization process of the sterilization device, the number of sterilization factors (reactive oxygen species) generated is relatively large and the survival time is relatively long, and the amount of ozone generated is relatively small, maintaining a high sterilization efficiency.

[0088] Figure 6 This is a schematic diagram of the corresponding relationship between humidity and sterilization rate in the embodiments of this application. As Figure 6 shown, when the humidity is between 30% and 90%, the sterilization rate increases with the increase of humidity.

[0089] Figure 7 This is a schematic diagram of the corresponding relationship between humidity and the number of reactive oxygen species in the embodiments of this application. As Figure 7 shown, when the humidity is between 30% and 90%, the number of reactive oxygen species increases with the increase of humidity. Electron-hole pairs react with water and oxygen to generate reactive oxygen species. The number of reactive oxygen species can be increased by increasing the humidity.

[0090] Figure 8 This is a schematic diagram of the corresponding relationship between humidity and the survival time of reactive oxygen species in the embodiments of this application. As Figure 8As shown, when the humidity is between 30% and 90%, the survival time of reactive oxygen species increases with the increase of humidity. That is to say, as the humidity increases, the survival time of reactive oxygen species increases.

[0091] Figure 9 This is a schematic diagram of the corresponding relationship between humidity and ozone concentration in the embodiment of the present application. As Figure 9 shown, when the humidity is between 30% and 90%, the ozone concentration decreases with the increase of humidity. Ozone reacts with water to generate reactive oxygen species. Therefore, while the reactive oxygen species increase, the amount of ozone can be reduced.

[0092] In order to reflect the sterilization effect of the embodiment of the present application, the embodiment of the present application compares the sterilization effects of four different sterilization control methods in the same sterilization environment.

[0093] Using Method 1: Start the sterilization device and the timing device. The power of the ultraviolet lamp is the first power, and the sterilization duration is the first duration. After the timing ends, determine that the sterilization rate is a;

[0094] Using Method 2: Start the sterilization device and the timing device. The power of the ultraviolet lamp is the first power, and extend the sterilization duration to 1.2 times the first duration. After the timing ends, determine that the sterilization rate is b;

[0095] Using Method 3: Start the sterilization device and the timing device. Increase the power of the ultraviolet lamp to 1.2 times the first power, and the sterilization duration is the first duration. After the timing ends, determine that the sterilization rate is c;

[0096] Using Method 4 (i.e., any one of the sterilization control methods in the above embodiment): Start the sterilization device and the timing device. The power of the ultraviolet lamp is the first power, and the sterilization duration is the first duration. After the timing ends, determine that the sterilization rate is d.

[0097] Here, the first duration can be 0.5 h or 1 h, and the maximum power of the ultraviolet lamp can be 10 W.

[0098] Figure 10 This is a comparison chart of the sterilization rates of four sterilization control methods in the embodiment of the present application. As Figure 10 shown, the sterilization rate d is higher than the sterilization rates a, b, and c.

[0099] To implement the method of the embodiment of the present application, based on the same inventive concept, the embodiment of the present application also provides a sterilization control device. As Figure 11 shown, the device 110 includes:

[0103] In some embodiments, in the corresponding relationship, the greater the sterilization environment humidity, the smaller the atomization rate of the humidifying device.

[0104] In some embodiments, the corresponding relationship includes: converting the first sterilization environment humidity based on a preset first conversion formula to obtain a third atomization rate; summing the third atomization rate and the default atomization rate of the humidifying device to obtain the first atomization rate.

[0110] In some embodiments, the control unit 1103 is further configured to control the humidifying device to stop performing the humidifying operation when the first sterilization environment humidity is greater than or equal to a first humidity threshold.

[0113] Of course, in practical applications, as Figure 12 shown, the various components in the device are coupled together through a bus system 1203. It can be understood that the bus system 1203 is used to realize the connection and communication between these components. In addition to the data bus, the bus system 1203 also includes a power bus, a control bus, and a status signal bus. However, for the sake of clear illustration, in Figure 12 all kinds of buses are labeled as the bus system 1203.
