Detailed Description
The following detailed description of embodiments of the present application will be described in conjunction with the accompanying drawings and examples. The following examples are intended to illustrate the present application but are not intended to limit the scope of the present application.
First, a number of terms referred to in this application are introduced:
negative Temperature Coefficient (NTC) Temperature sensors generally refer to semiconductor materials or components with large Negative Temperature coefficients. The operation principle is as follows: the resistance value decreases rapidly with increasing temperature.
Figure 1 is a schematic diagram of a blower according to one embodiment of the present application. As shown in fig. 1, the blower includes at least a processing component 110, a heat generating device 120, and a temperature sensor 130.
In the present application, the number of the heat generating devices 120 is at least two (the first heat generating device 121 and the second heat generating device 122). The number of the second heat generating devices may be one or more.
In one example, the hair dryer includes an inner coil heater 122 and an outer coil heater 121 nested outside the inner coil heater. The resistance value of the outer ring heating wire 121 is greater than that of the inner ring heating wire 122, and the heat dissipation efficiency of the outer ring heating wire 121 is greater than that of the inner ring heating wire 122; in order to ensure that the distribution strategy of the full power of the hair dryer is adapted, the span of the opening sequence of the outer ring heating wire 121 is larger than that of the inner ring heating wire 122; the maximum power point of the outer-ring heating wire 121 is greater than that of the inner-ring heating wire 122. In this example, only the first heat generating device is used as an outer-ring heating wire and the second heat generating device is used as an inner-ring heating wire for explanation, in practical implementation, the first heat generating device and the second heat generating device may be arranged in other manners, and the arrangement manner of the first heat generating device and the second heat generating device is not limited in this embodiment.
Wherein, the opening sequence means that the heating device keeps opening in the working period.
In this embodiment, by providing a plurality of heat generating devices 120, full coverage of power from 0 to the maximum power can be ensured, and each heat generating device 120 does not emit red at the maximum power.
The temperature sensor 130 is used to collect the temperature of the first heat generating device 121. Alternatively, the temperature sensor 130 may be an NTC temperature sensor, and of course, may also be another type of sensor for collecting temperature, and the embodiment does not limit the type of the temperature sensor.
The processing assembly 110 is communicatively coupled to the heat generating device 120 and the temperature sensor 130, respectively.
The processing component 110 is configured to obtain a target power of the blower; acquiring the opening sequence proportion of the first heating device and the second heating device; acquiring the heating power of a first heating device; determining the complete machine power of the blower based on the heating power and the opening sequence proportion; the integrator power is adjusted based on the target power.
The opening sequence proportion refers to the proportion between the time length of the first heating device and the time length of the second heating device which are kept on in the same working cycle.
Because the temperature sensor 130 can only collect temperature data of one heating device, if the complete machine power of the blower is directly determined based on the temperature data, the obtained mapping relation is non-linear due to the existence of the power of other heating devices, and the efficiency of determining the complete machine power is low. In the embodiment, the heating power of the corresponding heating device is determined based on the temperature data, and then the complete machine power of the blower is determined based on the heating power and the opening sequence proportion, so that the nonlinear relation between the temperature data and the complete machine power is not required to be determined, and the efficiency of determining the complete machine power can be improved.
Fig. 2 is a flowchart of a power adjustment method according to an embodiment of the present application. In the present embodiment, the main implementation of each step is the processing component 110 in the hair dryer shown in fig. 1, and the method at least includes the following steps:
The target power refers to the adjusted power desired by the blower.
Optionally, the processing component reads the power corresponding to the current gear of the blower to obtain the target power. Such as: reading the power corresponding to the current gear of the blower when the blower is started; or reading the power corresponding to the current gear of the blower during gear shifting. Of course, the processing element may also obtain the target power in other scenarios, and this embodiment is not listed here.
The opening sequence proportion refers to the proportion between the time length of the first heating device and the time length of the second heating device which are kept on in the same working cycle.
The opening sequence proportion of the first heating device and the second heating device is prestored in the blower. Such as: the first heating device is an outer ring heating wire, the second heating device is an inner ring heating wire, and the opening sequence ratio of the first heating device to the second heating device is 3: 1. That is, in the same duty cycle (including the duty cycle of the first heat generating device and the duty cycle of the second heat generating device), the ratio of the period during which the first heat generating device is kept on to the period during which the second heat generating device is kept on is 3: 1.
Optionally, the processing component acquires temperature data acquired by the temperature sensor; the heating power of the first heating device is determined based on the temperature data. Wherein the temperature data is indicative of a current temperature of the first heat generating device.
Wherein determining the heating power of the first heating device based on the temperature data comprises: acquiring a mapping relation between temperature data and heating power; and determining the heating power corresponding to the temperature data based on the mapping relation.
Of course, the processing component may also obtain the heat generating power of the first heat generating device by other manners, such as: the heating power is calculated by collecting the voltage and the resistance of the first heating device, and the like, and the manner of obtaining the heating power of the first heating device is not limited in this embodiment.
And step 204, determining the complete machine power of the blower based on the heating power and the opening sequence proportion.
Wherein, confirm the complete machine power of hair-dryer based on heating power and opening sequence proportion, include: acquiring the sum of a numerator and a denominator in the opening sequence proportion; and calculating the product of the heating power divided by the ratio corresponding to the first heating device in the opening sequence proportion and the sum to obtain the power of the whole machine.
Such as: the opening sequence ratio of the first heating device to the second heating device is 3: 1; the power of the whole machine is P/3 (1+3) to 4P/3.
Optionally, adjusting the integral power based on the target power includes, but is not limited to, at least one of the following:
the first method comprises the following steps: calculating a power difference value between the power of the whole machine and the target power; distributing the power difference value according to the opening sequence proportion to obtain distributed power, wherein the distributed power comprises distributed power corresponding to the first heating device and distributed power corresponding to the second heating device; and adjusting the heating power of the first heating device to the distributed power corresponding to the first heating device, and adjusting the heating power of the second heating device to the distributed power corresponding to the second heating device. In other words, the processing component adjusts the overall power to the target power at one time.
And the second method comprises the following steps: controlling the heating power of the first heating device to increase or decrease the first power according to the opening sequence proportion, and controlling the heating power of the second heating device to increase or decrease the second power; obtaining the heating power of the first heating device is executed again; determining the complete machine power of the blower based on the heating power and the opening sequence proportion to obtain updated complete machine power; calculating the difference between the updated complete machine power and the target power; and when the difference value between the updated complete machine power and the target power is out of the preset range, the step of controlling the heating power of the first heating device to increase or decrease the first power according to the opening sequence proportion and controlling the heating power of the second heating device to increase or decrease the second power is executed again until the difference value between the updated complete machine power and the target power is in the preset range. In other words, the processing component gradually adjusts the overall power until the overall power reaches the target power.
Of course, the processing component may also be combined with the first and second power adjustment modes, and the updated power of the whole machine is obtained by first adjusting in the first mode; and then gradually approaching the target power based on the updated overall power by using a second mode.
In summary, the power adjustment method provided in this embodiment obtains the target power of the blower; acquiring the opening sequence proportion of the first heating device and the second heating device; acquiring the heating power of a first heating device; determining the complete machine power of the blower based on the heating power and the opening sequence proportion; adjusting the overall power based on the target power; the problem that the heating wire is easy to turn red when a single heating wire bears the power of the whole blower can be solved; the whole power of the blower is shared by arranging the plurality of heating devices, so that the whole power can be fully covered from 0 to the maximum power, and each heating device cannot be red at the maximum power. Meanwhile, because the temperature sensor can only collect the temperature data of one heating device usually, if the complete machine power of the blower is directly determined based on the temperature data, the obtained mapping relation is nonlinear due to the existence of the power of other heating devices, and the efficiency of determining the complete machine power is lower; in the embodiment, the overall power of the blower is determined based on the heating power and the opening sequence proportion of the heating device, and the efficiency of determining the overall power can be improved without determining the nonlinear relation between the temperature data of the heating device and the overall power.
