In order to illustrate the technical scheme of the application, the following description is made by specific examples.
Referring to fig. 1, fig. 1 is a flowchart of a method for controlling an air outlet temperature of a blower according to an embodiment of the present application. As shown in fig. 1, a method for controlling the temperature of the air outlet of a blower, the method comprises the following steps:
step 101, obtaining the target air outlet temperature of the blower.
The target air outlet temperature is specifically an ideal air outlet temperature set by a user. For example, the user adjusts a gear or a digital temperature control panel to set a control temperature.
In this embodiment, after the target air outlet temperature is obtained, the air outlet temperature of the blower is kept at the target air outlet temperature through a series of temperature control operations, so as to reduce the oscillation change of the air outlet hot air temperature caused by the change of the ambient temperature outside the air inlet.
Step 102, measuring the current air inlet temperature of the blower.
Wherein, the measurement of air intake temperature is realized through temperature sensor.
Specifically, a temperature sensor is arranged at the position of an air inlet of the blower; the current air inlet temperature is measured by the temperature sensor.
For example, the temperature sensor is positioned at the air inlet position on the handle of the blower, can be attached to the control circuit board of the blower, and can be independently attached to the air inlet position.
The temperature sensor may in particular be an NTC (Negative Temperature Coefficient ) sensor.
And step 103, determining target heating power according to a preset temperature and power relation table based on the target air outlet temperature and the current air inlet temperature.
The temperature and power relation table comprises the corresponding relation between the target air outlet temperature and the current air inlet temperature and heating power.
Specifically, a set of air outlet temperature and air inlet temperature corresponds to a heating power. On the basis, the set heating power corresponding to the target air outlet temperature and the current air inlet temperature can be obtained by matching according to a preset temperature and power relation table. The set heating power may be directly used as the target heating power, or the final target heating power may be obtained by performing power value processing based on the set heating power.
And 104, controlling the heating device to heat according to the target heating power.
The heating device is specifically a heating wire or other heating device.
The temperature and power relation table needs to be constructed before the target heating power is determined according to the preset temperature and power relation table based on the target air outlet temperature and the current air inlet temperature.
Specifically, referring to fig. 2, the step of constructing a temperature-power relationship table includes:
Step 201, measuring the temperature of an air outlet of the blower after the blower is controlled to heat by the heating device with different heating powers under different environmental temperatures.
And 202, taking the ambient temperature as an air inlet temperature, and establishing corresponding relations among different air inlet temperatures, different heating powers and air outlet temperatures to obtain the temperature and power relation table.
Here, it is necessary to measure the air outlet temperature of the product in advance under different conditions of heating power stabilization (i.e., air outlet temperature stabilization) at different ambient temperatures.
And a temperature power relation table (te, ts, p) table is established. Where te is the inlet temperature, p is the heating power, and ts is the outlet temperature.
Wherein, the corresponding relation among the temperature of each air inlet, the heating power and the temperature of the air outlet can be directly obtained, and the numerical value of each parameter is corresponding to generate a temperature power relation table.
Or different air inlet temperatures and air outlet temperatures can be subjected to gear division, different gears can correspond to a numerical value interval or a fixed numerical value, and the corresponding relation among the air inlet temperatures, the heating power and the air outlet temperatures is constructed by establishing the corresponding relation among the air inlet temperature gears, the air outlet temperature gears and the heating power, so that a temperature power relation table is obtained.
Correspondingly, in a specific embodiment, the establishing a correspondence between the different air inlet temperatures, the different heating powers and the air outlet temperatures, to obtain the temperature and power relationship table includes:
setting M air inlet temperature gears based on the air inlet temperature; m is a positive integer;
Setting N air outlet temperature gears based on the air outlet temperature; n is a positive integer;
Combining the M air inlet temperature gears and the N air outlet temperature gears to obtain M x N gear combinations;
Based on the measured corresponding relations among different air inlet temperatures, different heating powers and different air outlet temperatures in the blower, establishing the corresponding relation between each gear combination and different heating powers to obtain the temperature and power relation table.
When the M air inlet temperature gears are set based on the air inlet temperature, each air inlet temperature can be set to be one air inlet temperature gear, or the numerical distribution interval based on the air inlet temperature is set to be corresponding to each numerical distribution interval respectively.
When setting N air outlet temperature gears based on the air outlet temperature, one air outlet temperature gear may be set for each air outlet temperature, or the air outlet temperature gears corresponding to each numerical distribution interval may be set based on the numerical distribution interval of the air outlet temperature.
Specifically, an outlet temperature shift table ts [ L1] may be established, and each shift may correspond to a fixed temperature, wherein the temperatures are arranged from low to high.
Meanwhile, an air inlet temperature gear table te [ L2] can be established, and each gear can correspond to a fixed temperature, wherein the temperatures are arranged from low to high.
The temperature power relation table is organized into a 2-dimensional array p [ L1] [ L2], wherein L1 is the number of the temperature gear number of the air outlet, and L2 is the number of the temperature gear number of the air inlet.
When the M air inlet temperature gears and the N air outlet temperature gears are combined to obtain m×n gear combinations, specifically, in the process of measuring the air outlet temperature of the blower heated by the heating device with different heating powers under different environmental temperatures in step 201, the corresponding relations between the different environmental temperatures, the heating powers and the heated air outlet temperature respectively combine the data gears to which each data belongs to obtain m×n gear combinations.
When the correspondence between each gear combination and the heating power is established to obtain the temperature and power relationship table, the correspondence between m×n gear combinations and the heating power is finally set as the temperature and power relationship table based on the correspondence between the different air inlet temperatures, the different heating powers and the different air outlet temperatures measured in step 201.
For example, the inlet temperature is 20 degrees, the heating power is 1000w, and the outlet temperature after heating is 30 degrees. And forming a gear combination between a 2 nd gear air inlet temperature gear to which the 20-degree air inlet temperature belongs and a 2 nd gear air outlet temperature gear to which the 30-degree air outlet temperature belongs based on the heating corresponding relation among the three, and establishing a corresponding relation between the gear combination and the heating power of 1000 w.
After the temperature and power relation table is set, the step of determining the target heating power according to the preset temperature and power relation table based on the target air outlet temperature and the current air inlet temperature can be executed on the basis.
The determining, as an optional implementation manner, the target heating power based on the target air outlet temperature and the current air inlet temperature according to a preset temperature and power relation table specifically includes:
selecting a target air outlet temperature gear matched with the target air outlet temperature from M air inlet temperature gears, selecting a target air inlet temperature gear matched with the current air inlet temperature from N air outlet temperature gears, and determining a target gear combination corresponding to the target air outlet temperature gear and the target air inlet temperature gear;
and matching the preset temperature and power relation table to obtain set heating power with a corresponding relation with the target gear, and determining the target heating power based on the set heating power.
Each air inlet temperature gear corresponds to a rated air inlet temperature value, and each air outlet temperature gear corresponds to a rated air outlet temperature value.
In a specific embodiment, selecting a target outlet temperature gear matching the target outlet temperature from M air inlet temperature gears, and selecting a target inlet temperature gear matching the current inlet temperature from N air outlet temperature gears, including:
When the target air outlet temperature is judged to be greater than or equal to a first rated air outlet temperature value and less than a second rated air outlet temperature value, selecting an air outlet temperature gear corresponding to the first rated air outlet temperature value as the target air outlet temperature gear;
And when the current air inlet temperature is judged to be greater than or equal to a first rated air inlet temperature value and less than a second rated air inlet temperature value, selecting an air inlet temperature gear corresponding to the first rated air inlet temperature value as the target air inlet temperature gear.
Otherwise, selecting an air inlet temperature gear corresponding to the second rated air outlet temperature value as the target air inlet temperature gear.
Namely, according to the set target air outlet temperature t1, a corresponding gear interval is found: for example, the temperature corresponding to the n-stage is ts [ n ], and the temperature corresponding to the n+1-stage is ts [ n+1]. If t1 is greater than or equal to ts n and t1 is less than ts n+1, then the target outlet temperature gear with the target outlet temperature is n gear.
Otherwise, the target air outlet temperature gear with the target air outlet temperature being matched is n+1 gear.
Wherein n is the number of the temperature gear of the air outlet. The value of n can be a continuous positive integer, and can be arranged from large to small or from small to large.
Similarly, according to the target air inlet temperature t2, a corresponding gear interval is found: for example, the temperature corresponding to m-level is te [ m ], and the temperature corresponding to m+1-level is te [ m+1]. If t2 is greater than or equal to te [ m ] and t2 is less than te [ m+1], the target air inlet temperature gear with the target air inlet temperature is m gear.
Otherwise, the target air inlet temperature gear with the target air inlet temperature being matched is m+1 gear.
Wherein m is the number of the temperature gear of the air inlet. The value of m can be a continuous positive integer, and can be arranged from large to small or from small to large.
Differently, in another specific embodiment, the selecting, from M air inlet temperature steps, a target air outlet temperature step that matches the target air outlet temperature, and selecting, from N air outlet temperature steps, a target air inlet temperature step that matches the current air inlet temperature includes:
When the difference value between the target air outlet temperature and the third rated air outlet temperature value is smaller than the difference value between the target air outlet temperature and the fourth rated air outlet temperature value, selecting an air outlet temperature gear corresponding to the third rated air outlet temperature value as the target air outlet temperature gear; wherein the third rated outlet temperature value and the fourth rated outlet temperature value correspond to two adjacent outlet temperature gears;
when the difference value between the current air inlet temperature and a third rated air inlet temperature value is smaller than the difference value between the current air inlet temperature and a fourth rated air inlet temperature value, selecting an air inlet temperature gear corresponding to the third rated air inlet temperature value as the target air inlet temperature gear; and the third rated air inlet temperature value and the fourth rated air inlet temperature value correspond to two adjacent air inlet temperature gears.
Otherwise, selecting an air inlet temperature gear corresponding to the fourth rated air outlet temperature value as the target air inlet temperature gear.
Namely, according to the set target air outlet temperature t1, a corresponding gear interval is found: if t1-ts [ n ] > ts [ n+1] -t1, the target air outlet temperature gear with the target air outlet temperature being matched is n+1 gear, otherwise n gear.
Likewise, according to the target air inlet temperature t2, a corresponding gear interval is found: if t2-te [ m ] > te [ m+1] -t2, the target air inlet temperature gear with the target air inlet temperature being matched is m+1, otherwise, m.
The power value of the target heating power gear is thus obtained as: p [ n ] [ m ], or p [ n ] [ m+1], or p [ n+1] [ m ].
Further, in an embodiment, the determining the target heating power based on the set heating power includes:

Wherein n+1 is the number of the adjacent air outlet temperature gear of the target air outlet temperature gear, m+1 is the number of the adjacent air inlet temperature gear of the target air inlet temperature gear, and p [ n+1] [ m+1] is the heating power corresponding to the gear combination formed by the adjacent air outlet temperature gear of the target air outlet temperature gear and the adjacent air inlet temperature gear of the target air inlet temperature gear.
Wherein ts [ n+1] is the rated outlet temperature value of the adjacent outlet temperature shift of the target outlet temperature shift, and te [ m+1] is the rated inlet temperature value of the adjacent inlet temperature shift of the target inlet temperature shift.
In the process, the heating power calculation is realized more accurately by an interpolation method.
Wherein k1 and k2 are adjustment values determined through experiments so as to reduce the influence deviation of the temperature of the air inlet and the influence deviation of the temperature of the air outlet as much as possible.
