Detailed Description

So that the manner in which the features and elements of the present embodiments can be understood in detail, a more particular description of the embodiments, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings.

The embodiment of the application provides a sterilization control method for solving the problem of low air sterilization efficiency of the existing household appliance, and the method is applied to the household appliance. For example, as shown in fig. 1, the household electrical appliance 10 may include a sterilization device 11 and a humidification device 12, the sterilization device 11 is disposed in an air outlet duct of the household electrical appliance 10, and the humidification device 12 is used for adjusting humidity in the sterilization duct of the sterilization device 11.

Fig. 2 is a schematic view of a first process of a sterilization control method in an embodiment of the present application, and as shown in fig. 2, the method may specifically include:

step 201: acquiring first sterilization environment humidity in a sterilization channel;

here, the first sterilization ambient humidity is acquired by a humidity sensor disposed within the sterilization channel. The first ambient humidity may be understood as the current humidity within the sterilisation channel.

Step 202: determining a first atomization rate of the humidifying device based on the first sterilization environment humidity and a preset corresponding relation; wherein, the corresponding relation is used for representing the corresponding relation between the humidity of the sterilization environment and the atomization rate;

for example, in some embodiments, the greater the humidity of the sterilization environment, the smaller the atomization rate of the humidifier.

It should be noted that, in a certain humidity range, the higher the humidity of the sterilization environment is, the smaller the requirement for humidity adjustment by the humidifying device is, that is, the higher the atomization rate of the sterilizing device is; the lower the humidity of the sterilization environment is, the greater the need for humidity adjustment by the humidifying device is, i.e. the lower the atomization rate of the sterilization device is.

In the embodiment of the application, the corresponding relationship is used for representing the corresponding relationship between the humidity of the sterilization environment and the atomization rate, and the corresponding relationship may 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 may be determined in a calculation manner, or the atomization rate corresponding to the first sterilization environment humidity may be searched in a table look-up manner.

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

The first conversion formula includes: the product of the first sterilizing ambient humidity and the second constant is subtracted from the first constant.

Illustratively, the formula for calculating the correspondence relationship is: y = C0+ (C1-x/C2), where C0 is a default atomization rate of the humidification device, C1 is a first constant, 1/C2 is a second constant, x is a first sterilization ambient humidity, and y is a first atomization rate.

For example, in some embodiments, the correspondence relationship is further used to characterize the correspondence relationship between the power of the ultraviolet lamp and the atomization rate in the sterilization passage, and the higher the power of the ultraviolet lamp, the higher the atomization rate of the humidification device.

The principle that the ultraviolet lamp irradiates the photocatalyst filter screen for sterilization is that the ultraviolet lamp irradiates the photocatalyst to form an electron-hole pair, and the electron-hole pair reacts with surrounding water molecules and oxygen molecules to generate hydroxyl radicals and superoxide ion radicals with strong oxidizing property, so that sterilization is realized. In a certain power range, the higher the power of the ultraviolet lamp is, the higher the irradiation intensity of the photocatalyst filter screen is, and the higher the requirement on the environmental humidity is, so that when the power of the ultraviolet lamp is increased, the atomization rate of the humidifying device needs to be increased, and the sterilization environmental humidity is maintained in the optimal humidity range.

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

Illustratively, the formula for calculating the correspondence is: y = C0+ a (C1-x/C2), where C0 is a default atomization rate of the humidification device, C1 is a first constant, 1/C2 is a second constant, a is a weighting coefficient, x is a first sterilization ambient humidity, and y is a first atomization rate.

The magnitude of a is influenced by the power of the ultraviolet lamp, and the larger the power of the ultraviolet lamp, the larger the a is. For example, the power of the ultraviolet lamp and a are in a linear relation or a non-linear exponential relation, a can range from 0.01 to 0.1, and the wavelength of the ultraviolet lamp can be 185nm or 254nm.

For example, in some embodiments, the correspondence relationship is also used to characterize the correspondence relationship between the air speed and the nebulization rate in the disinfection channel, and the greater the air speed in the disinfection channel, the greater the nebulization rate of the humidifying device.

It should be noted that, the higher the wind speed in the sterilizing channel is, the faster the air passes through the sterilizing channel, the faster the humidity of the sterilizing environment is reduced due to the influence of the wind speed, and in order to improve the sterilizing efficiency, the atomization rate of the humidifying device should be increased when the wind speed is higher. The larger the wind speed in the sterilization channel is, the smaller the speed of air passing through the sterilization channel is, the lower the humidity is, or even no influence is caused by the humidity of the sterilization environment to the wind speed, and in order to improve the sterilization efficiency, the atomization rate of the humidifying device should be reduced, or even the humidifying device should be closed when the wind speed is low. The sterilization effect is prevented from being influenced by water drops condensed in the sterilization channel.

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

Illustratively, the formula for calculating the correspondence relationship is: y = C0+ b (C1-x/C2), where C0 is a default atomization rate of the humidification device, C1 is a first constant, 1/C2 is a second constant, b is a weighting coefficient, x is a first sterilization ambient humidity, and y is a first atomization rate.

The size of b is influenced by the wind speed in the sterilization channel, and the larger the wind speed is, the larger the b is. For example, the wind speed and b are linear or non-linear exponential.

Step 203: and when the first atomization rate is inconsistent with the current second atomization rate of the humidifying device, controlling the humidifying device to perform humidifying operation at the first atomization rate so as to adjust the humidity of the sterilizing environment in the sterilizing channel.

Here, the first atomization rate is determined according to the first sterilization environment humidity, and when the first atomization rate is 0, the control unit controls the humidification device to stop the humidification operation. The second atomization rate is the current atomization rate of the humidifying device, and when the second atomization rate is 0, the humidifying device is marked to be in a closed state.

The first atomization rate and the second atomization rate are inconsistent, and the characterization requires adjusting the atomization rate of the humidification device according to the first atomization rate.

The method further comprises the following steps: and when the first atomization rate is consistent with the second atomization rate, controlling the humidifying device to continuously perform humidifying operation at the second atomization rate.

Exemplarily, fig. 3 is a schematic diagram of a first structure of a sterilization device and a humidification device in an embodiment of the present application, and as shown in fig. 3, the sterilization device may include: the sterilizing device is positioned in an air outlet duct 31 of the household appliance, and the spray head of the humidifying device 12 is positioned in a sterilizing channel to spray atomized water vapor into the sterilizing channel so as to adjust the humidity in the sterilizing channel.

For example, fig. 4 is a second structural schematic diagram of the sterilization device and the humidification device in the embodiment of the present application, and as shown in fig. 4, the spray head of the humidification device 12 may also be located outside the sterilization channel, but point to the sterilization channel, so as to ensure that the atomized water vapor can be blown into the sterilization channel.

By adopting the technical scheme, the atomization rate of the humidifying device is adjusted according to the sterilization environment humidity in the sterilization channel, so that the sterilization environment humidity in the sterilization channel is maintained in the optimal humidity range, and therefore, the sterilization device has the advantages of more sterilization factors, longer survival time, less generated ozone amount and higher sterilization efficiency in the sterilization process.

To further illustrate the object of the present application based on the above embodiments of the present application, as shown in fig. 5, the method specifically includes:

step 501: acquiring a first sterilization environment humidity in a sterilization channel;

step 502: judging whether the first sterilization environment humidity is smaller than a second humidity threshold value, if so, executing a step 503; if not, go to step 505;

here, the second humidity threshold value is smaller than the first humidity threshold value, and the first humidity threshold value and the second humidity threshold value are upper and lower limit values of the optimum humidity range. In the optimal humidity range, the sterilization device generates a large amount of sterilization factors and a long survival time, generates a small amount of ozone and maintains high sterilization efficiency in the sterilization process.

Step 503: determining a first atomization rate of the humidifying device based on the first sterilization environment humidity and a preset corresponding relation; wherein, the corresponding relation is used for representing the corresponding relation between the humidity of the sterilization environment and the atomization rate;

for example, in some embodiments, the greater the humidity of the sterilization environment, the lower the atomization rate of the humidifier device in the correspondence.

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

Illustratively, the formula for calculating the correspondence relationship is: y = C0+ (C1-x/C2), where C0 is a default nebulization rate of the humidifying device, C1 is a first constant, 1/C2 is a second constant, x is a first germicidal ambient humidity, and y is a first nebulization rate.

For example, in some embodiments, the correspondence relationship is also used to characterize the correspondence relationship between the power of the ultraviolet lamp and the atomization rate in the sterilization passage, and the greater the power of the ultraviolet lamp, the greater the atomization rate of the humidification device.

Illustratively, the formula for calculating the correspondence is: y = C0+ a (C1-x/C2), where C0 is a default nebulization rate of the humidification device, C1 is a first constant, 1/C2 is a second constant, a is a weighting coefficient, x is a first sterilization ambient humidity, and y is a first nebulization rate.

For example, in some embodiments, the correspondence relationship is further used to characterize the correspondence relationship between the wind speed and the atomization rate in the disinfection channel, and the larger the wind speed in the disinfection channel, the larger the atomization rate of the humidification device.

Illustratively, the formula for calculating the correspondence is: y = C0+ b (C1-x/C2), where C0 is a default atomization rate of the humidification device, C1 is a first constant, 1/C2 is a second constant, b is a weighting coefficient, x is a first sterilization ambient humidity, and y is a first atomization rate.

Step 504: when the first atomization rate is inconsistent with the current second atomization rate of the humidifying device, controlling the humidifying device to execute humidifying operation at the first atomization rate so as to adjust the sterilizing environment humidity in the sterilizing channel;

Step 505: judging whether the first sterilization environment humidity is larger than a first humidity threshold value, if not, executing a step 506; if yes, go to step 507;

step 506: controlling the humidifying device to continue to perform humidifying operation at the second atomization rate;

step 507: controlling the humidifying device to stop performing the humidifying operation.

By adopting the technical scheme, the atomization rate of the humidifying device is adjusted according to the sterilization environment humidity in the sterilization channel, so that the sterilization environment humidity in the sterilization channel is maintained in the optimal humidity range, and therefore, the sterilization device generates a large number of sterilization factors (active oxygen) and has a long survival time, generates a small amount of ozone and maintains high sterilization efficiency in the sterilization process.

Fig. 6 is a schematic diagram illustrating a correspondence relationship between humidity and sterilization rate in the embodiment of the present application, and as shown in fig. 6, when the humidity is between 30% and 90%, the sterilization rate increases with the increase of the humidity.

FIG. 7 is a schematic diagram illustrating a relationship between humidity and active oxygen amount in an embodiment of the present application, and as shown in FIG. 7, when the humidity is between 30% and 90%, the active oxygen amount increases with the increase of the humidity. The electron-hole pairs react with water and oxygen to form reactive oxygen species, the amount of which can be increased by increasing the humidity.

Fig. 8 is a schematic diagram of the correspondence between humidity and active oxygen survival time in the embodiment of the present application, and as shown in fig. 8, when the humidity is between 30% and 90%, the active oxygen survival time increases with the increase of the humidity. That is, humidity increases and the active oxygen survival time increases.

FIG. 9 is a schematic diagram illustrating a correspondence relationship between humidity and ozone concentration in the embodiment of the present application, and as shown in FIG. 9, when the humidity is between 30% and 90%, the ozone concentration decreases with the increase of the humidity. Ozone reacts with water to generate active oxygen, so that the amount of ozone can be reduced while the active oxygen is increased.
