The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The existing scheme for controlling the refrigeration output basically adjusts the output power of the refrigeration module in real time through a temperature sensor, and the problem that the output regulation of the refrigeration module is delayed due to the insensitivity of the temperature sensor, and then the temperature is greatly floated exists in the scheme. That is to say, the temperature balance of the existing refrigeration control scheme is poor, and especially when the load change is large, the change error of the temperature detected by the temperature sensor is easily increased, so that the refrigeration module can not be stabilized at the preset temperature threshold basically. Based on this, the embodiment of the invention provides a temperature balance control method and device, which determine the duty ratio of PWM through a load value, so as to adjust the output power of a refrigeration module, so that the refrigeration module is quickly stabilized at a preset temperature threshold.
For the convenience of understanding the present embodiment, a detailed description will be given to a temperature balance control method disclosed in the present embodiment.
The first embodiment is as follows:
fig. 1 is a flowchart of a temperature balance control method according to an embodiment of the present invention.
Referring to fig. 1, a temperature balance control method provided in an embodiment of the present invention may include the following steps:
and S100, acquiring the current temperature of the refrigeration module by using a temperature sensor.
In order to rapidly reduce the temperature of the skin to improve the comfort of hair removal, embodiments of the present invention incorporate a cooling module into the hair removal device. The temperature sensor can be in contact with the refrigeration module for acquisition and can also be in non-contact with the refrigeration module for acquisition, and the embodiment of the invention does not specifically limit the acquisition mode of the temperature sensor.
And S102, if the current temperature is higher than the preset temperature threshold, starting the refrigeration module so that the refrigeration module reduces the current temperature to the preset temperature threshold.
When the current temperature is higher than the preset temperature threshold value, if the depilating instrument is directly used for working, the skin can be pricked. Therefore, the refrigeration module can be started first to reduce the current temperature higher than the preset temperature threshold to the preset temperature threshold, so that the current temperature of the refrigeration module is ensured to be stabilized at the preset temperature threshold.
And step S104, after the current temperature of the refrigeration module is reduced to a preset temperature threshold value, judging whether a load is connected to the refrigeration module or not under the condition that the current temperature is increased again.
In the embodiment of the present invention, the factors causing the current temperature to rise again are mainly classified into two types, namely, the self factor and the external factor. Wherein the self factor can indicate the working state of the depilating instrument, and the external factor can indicate the ambient temperature. Aiming at the temperature rise caused by different factor types, the embodiment of the invention controls the refrigeration module in different modes. Therefore, embodiments of the present invention should first determine the type of factor that causes the temperature to rise.
The method for determining the type of the factor causing the temperature rise is to judge whether a load is connected to the refrigeration module, that is, whether an input is detected by a touch on the refrigeration module. If the refrigeration module is connected with a load, the depilating instrument is in a working state, and the temperature rises due to self factors; if the refrigeration module is not connected with a load, the temperature rises again due to external factors, and the depilating instrument is in a non-working state.
And S106, if the refrigeration module is connected with a load, judging whether the depilating instrument in which the refrigeration module is positioned is in a lighting state.
In the embodiment of the invention, under the condition that the refrigeration module is connected with a load, the depilating instrument has two working states, wherein one working state is that the depilating instrument is in a light-up state, and the other working state is that the depilating instrument is in a state to be light-up state. The basis for distinguishing the working states of the two depilating instruments is as follows: whether the depilating instrument is in contact with the skin or not, and if the depilating instrument is in contact with the skin, the depilating instrument is in a polishing state; if the depilating instrument is not in contact with the skin, the depilating instrument is in a state of waiting to be polished. The purpose of this step is to determine the operating state of the epilating apparatus.
And S108, if the depilating instrument is in the lighting state, extracting the state information of the depilating instrument in the lighting state, and determining the load value of the load according to the state information.
In an embodiment of the present invention, the status information includes at least one of: gear, rate, temperature drop time of polishing. The temperature drop time may refer to a time for the refrigeration module to drop to a temperature equilibrium interval after reaching a preset temperature threshold. For example, the preset temperature threshold is 20 degrees, a section (19-21 degrees) in which the preset temperature threshold is floated by 1 degree is set as a temperature balance section, and the temperature drop time is the time taken by the current temperature of the refrigeration module to rise from 20 degrees to 21 degrees or fall from 20 degrees to 19 degrees. And determining the load value of the load, namely judging the load size of the refrigeration module, wherein the basis for judging the load size of the refrigeration module is the state information. Specifically, the higher the light striking gear and the faster the light striking speed of the depilating apparatus, the larger the load value of the load; the shorter the time for the refrigeration module to fall to temperature equilibrium after reaching temperature equilibrium, the greater the load value of the load. The embodiment of the invention can determine the load value of the current load by combining the various state information.
And step S110, adjusting the duty ratio of the PWM according to the load value based on the corresponding relation between the preset load value and the duty ratio of the PWM.
In an embodiment of the present invention, PWM digitally encodes the analog signal level. Duty cycle may refer to the ratio of the time taken for a PWM high to the total cycle time. The larger the duty cycle, the longer the PWM high level lasts. And determining the one-to-one correspondence between the load values and the duty ratios according to the preset correspondence between the load values and the duty ratios of the PWM. Generally, the larger the load value is, the larger the duty ratio is; conversely, the smaller the load value, the smaller the duty cycle. This step may adjust the duty cycle in real time based on the load value. Illustratively, if the refrigeration module is connected with a load and the depilating apparatus is not in a lighting state, the duty ratio is 50%; if the refrigeration module is switched in without load, the duty ratio is set to 10%. If the lighting gear is low, the lighting speed is low, the temperature drop time is long, the load of the refrigeration module is proved to be small, and the duty ratio can be set to 70%. On the contrary, if the lighting gear is high, the lighting speed is high, and the temperature drop time is short, which proves that the load of the refrigeration module is large, and the duty ratio can be set to 100%.
The PWM high level is the high-power work of the refrigeration module, and the low level is the low-power work or the non-work of the refrigeration module. Under the condition that the refrigeration module is in no load, after the current temperature is reduced to a preset temperature threshold value, the output power of the refrigeration module is controlled by PWM with a lower duty ratio, and at the moment, the low level of the PWM indicates that the refrigeration module does not work. Under the condition that the refrigeration module is loaded, after the current temperature is reduced to a preset temperature threshold value, adjusting a duty ratio corresponding to the load according to the load value to control the output of the refrigeration module, wherein the low level of PWM indicates that the refrigeration module does not work; when the load value is increased to a certain degree, the low level of the PWM indicates that the refrigeration module works at low power; and if the load of the refrigeration module is overlarge, the refrigeration module outputs full power.
And step S112, controlling the output power of the refrigeration module based on the duty ratio of the PWM.
According to the embodiment of the invention, the output of the refrigeration module is controlled to reach temperature balance in a PWM (pulse width modulation) mode. The larger the duty cycle, the larger the output power. According to the embodiment of the invention, the duty ratio of PWM is determined based on the load value, and then the output power of the refrigeration module is controlled by the duty ratio. Compared with the existing refrigeration module power control method, the embodiment of the invention has the advantages that: after the current temperature reaches the preset temperature threshold, the output power of the refrigeration module is controlled by adopting a PWM (pulse-width modulation) duty ratio control mode, so that the refrigeration module can be quickly stabilized at the preset temperature threshold.
The existing refrigeration control method has poor temperature balance, and particularly when the load changes greatly, the temperature change error detected by a temperature sensor is greatly increased, so that the refrigeration module can not be stabilized at the preset temperature threshold basically. The temperature balance control method provided by the embodiment of the invention comprises the steps of firstly, acquiring the current temperature of a refrigeration module by using a temperature sensor; then, when the current temperature is higher than a preset temperature threshold value, starting a refrigeration module so that the refrigeration module reduces the current temperature to the preset temperature threshold value; under the condition that the current temperature rises, judging whether a load is connected to the refrigeration module; if the refrigeration module is connected with a load, judging whether the depilating instrument in which the refrigeration module is positioned is in a light-up state; if the depilating instrument is in the light-up state, extracting the state information of the depilating instrument in the light-up state, and determining the load value of the load according to the state information; based on the corresponding relation between the preset load value and the duty ratio of the PWM, the duty ratio of the PWM is adjusted according to the load value; and finally, controlling the output power of the refrigeration module based on the duty ratio of the PWM. According to the embodiment of the invention, the exact load value can be obtained through the state information of the depilating instrument, and then the corresponding PWM duty ratio is determined through the load value, so that the output power of the refrigeration module is adjusted, and the refrigeration module is rapidly stabilized at the preset temperature threshold value.
Further, referring to fig. 2, another temperature balance control method according to an embodiment of the present invention, after step S100, further includes:
and S101, if the current temperature is lower than or equal to a preset temperature threshold value, closing the refrigeration module.
In the embodiment of the present invention, there are two cases of the reason for the current temperature being lower than or equal to the preset temperature threshold, one is controlled by the duty ratio of PWM, in which case, there is a possibility that the current temperature is greater than the preset temperature threshold after the cooling module is turned off. Another reason is environmental impact. For example, the epilator may be used normally in an environment of-20 degrees, even if the cooling module is not switched on, the current temperature does not reach the preset temperature threshold at the highest. Whatever the reason, as long as the current temperature is lower than or equal to the preset temperature threshold, the refrigeration module is closed.
Further, after step S104, the method further includes:
and step S105, if the refrigeration module is not loaded, controlling the output power of the refrigeration module based on the preset first duty ratio of the PWM so as to enable the current temperature to reach a preset temperature threshold value.
According to the embodiment of the invention, under the condition that a load is connected and the depilating instrument is in a lighting state, the duty ratio can be used for controlling the refrigeration module to work, wherein the duty ratio is adjusted in real time according to the load value. Under the condition that the refrigeration module is not connected with a load, in order to stabilize the current temperature at a preset temperature value, the refrigeration module is controlled to work by utilizing the duty ratio, and the difference point is that: the duty ratio of the refrigeration module is not required to be adjusted in real time under the condition that no load is connected, so that a fixed value can be set for the duty ratio, namely the preset first duty ratio of PWM, and then the output power of the refrigeration module is controlled by utilizing the preset first duty ratio, wherein the preset first duty ratio can mean 10% for example.
Further, after step S106, the method further includes:
and S107, if the depilating instrument is not in the lighting state, controlling the output power of the refrigeration module based on the preset second duty ratio of the PWM so as to enable the current temperature to reach the preset temperature threshold value, wherein the preset second duty ratio is larger than the preset first duty ratio.
When the refrigeration module is connected with a load and the depilating instrument is not in a lighting state, the refrigeration module is also controlled by utilizing the duty ratio in order to stabilize the current temperature at a preset temperature value. The duty ratio under this condition also does not need to be adjusted in real time, so a fixed value can be set for the duty ratio, that is, the preset second duty ratio of PWM is used to control the output power of the refrigeration module, and for example, the preset second duty ratio may refer to 50%.
In the embodiment of the invention, under the condition that the load is connected and the depilating instrument is in a light-up state, the exact load value can be obtained through the state information of the depilating instrument, and then the corresponding PWM duty ratio is determined through the load value; under the condition that no load is connected, the duty ratio can be set to be a fixed value according to the actual condition, namely, the first duty ratio is preset; under the conditions that a load is connected and the depilating instrument is in a lighting state, the duty ratio can be set to be a fixed value according to the actual condition, namely, the second duty ratio is preset; the embodiment of the invention reasonably sets the duty ratio under different states of the depilating instrument, and then adjusts the output power of the refrigeration module by utilizing the duty ratio in the PWM mode, so that the refrigeration module can be quickly stabilized at the preset temperature threshold value.
