[0036] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following will describe in detail the implementation methods of the present invention in conjunction with the accompanying drawings and embodiments, so as to fully understand how the present invention uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0037] Many specific details are set forth in the following description in order to provide a thorough understanding of the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited by the specific embodiments disclosed below.

[0038] Example 1

[0039] In terms of temperature control of current electric heaters, the common practice is as follows: compare the sampled ambient temperature with the target temperature set by the user. When the ambient temperature reaches the target temperature, control the electric heater to stop operating; when the ambient temperature is lower than the preset value of the target temperature (for example, 2 - 3°C lower than the target temperature), control the electric heater to resume operation. However, due to the delay between the heating of the heating element of the electric heater and the adjustment of the ambient temperature, the above control method may cause the overshoot value of the temperature to be too large, resulting in a large fluctuation of the ambient temperature. That is, the existing technology has the problem of poor ambient temperature stability, greatly reducing the comfortable experience of users when using electric heaters.

[0040] Taking an actual test as an example, when testing a certain electric heater using the above temperature control method and setting its target temperature to 22°C, its theoretical temperature control range should be 20 - 22°C. However, the actual measured ambient temperature fluctuation range is 16 - 23°C, and the temperature deviation is as high as 7°C, greatly affecting the comfort of users.

[0041] The present invention effectively maintains the basic stability of the temperature by detecting the change of the ambient temperature in real time, feeding back the detected ambient temperature to the main control, and then the main control determines and adjusts the heat output (power output) according to the ambient temperature value, so that the heat output of the electric heater reaches an equilibrium with the ambient heat loss.

[0042] Based on the above idea, an embodiment of the present invention provides a control method for an electric heater, as Figure 1 shown. The control method for the electric heater described in this embodiment includes step S101 and step S102. The specific contents of these steps are described in detail below:

[0043] Step S101, obtain the target temperature set by the user;

[0044] In this embodiment, the target temperature is the ambient temperature expected by the user, and the user can set the target temperature through the control panel, remote control, etc. of the electric heater. After the electric heater receives the target temperature set by the user, it will control the heating element (such as a thermocouple element) to heat at a certain power so that the ambient temperature within a certain range around the electric heater reaches the target temperature.

[0045] Step S102, during the heating process of the electric heater, when it is detected that the current ambient temperature reaches the target temperature, control the electric heater to perform a heating operation in an alternating manner with a first preset power and a second preset power, so as to maintain the current ambient temperature at the target temperature; wherein, the first preset power is greater than the second preset power.

[0046] In order to more effectively control the output temperature of the electric heater, during the heating process of the electric heater in this embodiment, when it is detected that the current ambient temperature reaches the target temperature, the electric heater is controlled to perform heating operations in an alternating manner with a first preset power and a second preset power, so as to maintain the current ambient temperature at the target temperature, including: during the heating process of the electric heater, when it is detected that the current ambient temperature reaches the target temperature, the electric heater is controlled to alternately execute S1 and S2, so that the current ambient temperature is within a preset temperature range with the target temperature as the intermediate value:

[0047] S1: Heat at the first preset power for a first preset time period;

[0048] S2: Heat at the second preset power for a second preset time period.

[0049] Specifically, when the current ambient temperature reaches the target temperature, the ambient temperature around the electric heater will always be in a high temperature state under the action of the current heating power. If heating continues at the current heating power, after a period of time, the ambient temperature may be higher than the target temperature and the temperature difference from the target temperature may be large. Therefore, adopting the above-mentioned alternating operation mode with the first preset power and the second preset power can reduce the heating power within a period of time, and then cause the ambient temperature to drop to a certain extent. The above operation mode enables the electric heater to finally operate at a relatively stable average power, making it easier to maintain the ambient temperature at the target temperature, rather than causing the ambient temperature to rise or fall too fast, which is convenient for subsequent gradual adjustment of the output power of the electric heater. In order to more precisely control the output temperature of the electric heater, the first preset power in this embodiment is the heating power corresponding to the highest gear available for the electric heater, and the second preset power in this embodiment is the heating power corresponding to the lowest gear available for the electric heater. And, the first preset time period is equal to the second preset time period.

[0050] Alternatively, the above-mentioned first preset power can also be the heating power corresponding to the second highest gear (i.e., one gear lower than the above-mentioned highest gear) available for the electric heater, and the above-mentioned second preset power can also be the heating power corresponding to the second lowest gear (i.e., one gear higher than the above-mentioned lowest gear) available for the electric heater. The first preset power and the second preset power can also be set to other heating powers according to actual needs, as long as the ambient temperature can be maintained at the target temperature during alternating operation. This embodiment does not make specific restrictions on this.

[0051] Specifically, when it is detected that the current ambient temperature reaches the target temperature set by the user, first control the electric heater to heat at a relatively high first preset power for a period of a minutes, and then control the electric heater to heat at a relatively low second preset power for a period of b minutes to control the change amount of the ambient temperature, so that the current ambient temperature can be within a preset temperature range with the above target temperature as the intermediate value. In this embodiment, the preset temperature range can be expressed as [T 目标 -Y, T 目标 +Y], where Y ≤ 2, and T 目标 is the target temperature. That is, in this embodiment, as long as the fluctuation of the ambient temperature does not differ from the target temperature by more than Y °C, it can be considered that the current ambient temperature is maintained at the target temperature set by the user.

[0052] For example, the preset temperature range can be specifically set as [T 目标 -0.5, T 目标 +0.5], [T 目标 -1, T 目标 +1], [T 目标 -2, T 目标 +2], etc. In practical applications, it can be specifically set according to actual needs, and this embodiment does not make specific restrictions on this.

[0053] When the first preset power is the heating power corresponding to the highest gear that the electric heater already has, and the second preset power is the heating power corresponding to the lowest gear that the electric heater already has, controlling the electric heater to alternately heat at the first preset power and the second preset power for the same period of time can make the heat output for the same period of time between high and low values, that is, make the final output power of the electric heater approximately the average value of the heating powers of the above highest gear and lowest gear, so that the ambient temperature is easier to be maintained at the target temperature without causing the ambient temperature to rise or fall too fast. In this way, the output temperature of the electric heater can be controlled more precisely, so that the current ambient temperature can be more stably maintained at the target temperature set by the user.

[0054] In order to more accurately detect the current ambient temperature, the electric heater described in this embodiment includes: a temperature sensing bulb provided on the housing of the electric heater. Then, in the heating process of the electric heater described in this embodiment, when it is detected that the current ambient temperature reaches the target temperature, controlling the electric heater to perform a heating operation in an alternating manner at the first preset power and the second preset power to maintain the current ambient temperature at the target temperature includes: in the heating process of the electric heater, when it is detected by the temperature sensing bulb that the current ambient temperature reaches the target temperature, controlling the electric heater to perform a heating operation in an alternating manner at the first preset power and the second preset power to maintain the current ambient temperature at the target temperature.

[0055] That is, in this embodiment, the temperature of the current environment is detected in real time by a temperature sensor disposed on the housing of the electric heater. Since the resistance value of the temperature sensor changes with the temperature, the temperature sensor can more sensitively sense the change in the ambient temperature. Moreover, the temperature sensor has a small volume and can be disposed inside the whole electric heater without affecting the overall appearance of the electric heater. Of course, in practical applications, other devices capable of detecting the ambient temperature can also be selected according to needs, and this embodiment does not make specific limitations thereon.

[0056] Specifically, the temperature sensor needs to be disposed inside the whole electric heater at a position far from the heating component or a position less affected by the heating component, and the temperature at this position is relatively consistent with the ambient temperature or has a consistent change rule, and can be used to characterize the change in the ambient temperature. Based on the above position setting principle, in this embodiment, the temperature sensor is preferably disposed at the housing of the electric heater. Since convection holes are provided at the housing, external air can enter the position of the temperature sensor through the convection holes, so that the temperature sensor can more sensitively detect the change in the ambient temperature. The temperature sensor detects the change in the ambient temperature by the change of its own resistance value with the temperature. In this embodiment, the detection frequency of the temperature sensor is set to detect once every 1 to 3 s.

[0057] In order to more precisely control the output temperature of the electric heater so that the ambient temperature can be more stably maintained at the target temperature, in the heating process of the electric heater described in this embodiment, when it is detected that the current ambient temperature reaches the target temperature, the electric heater is controlled to perform a heating operation in an alternating manner with a first preset power and a second preset power, so that the current ambient temperature is maintained at the target temperature, including: in the process of heating the electric heater with a third preset power, when it is detected that the current ambient temperature reaches the target temperature, the electric heater is controlled to perform a heating operation in an alternating manner with a first preset power and a second preset power, so that the current ambient temperature is maintained at the target temperature; wherein, the third preset power is less than the first preset power, and the third preset power is greater than the second preset power.

[0058] That is, in this embodiment, when the electric heater receives the target temperature set by the user, the electric heater starts to control the heating element to generate heat with a third preset power, so that the ambient temperature within a certain range around the electric heater reaches the target temperature. The third preset power is set to a value greater than the second preset power and less than the first preset power, so that when the electric heater subsequently operates alternately with the first preset power and the second preset power, the output heat can fluctuate up and down within a range centered on the output heat corresponding to the third preset power, and finally the output heat is a relatively stable heat value, and further the ambient temperature is more easily maintained at the target temperature without causing the ambient temperature to rise or fall too fast. In this way, the output temperature of the electric heater can be more precisely controlled, and further the ambient temperature can be more effectively and stably maintained at the above target temperature.

[0059] To further precisely control the output temperature of the electric heater so that the ambient temperature can be further stably maintained at the target temperature, as Figure 2 shown, the method described in this embodiment further includes: during the process of controlling the electric heater to perform heating operations in an alternating manner with the first preset power and the second preset power, detecting the current ambient temperature; determining whether the current ambient temperature is less than the minimum value of the preset temperature range; when the current ambient temperature is less than the minimum value of the preset temperature range, gradually increasing the first preset time period for which the electric heater performs heating with the first preset power until the current ambient temperature is within the preset temperature range.

[0060] To further precisely control the output temperature of the electric heater so that the ambient temperature can be further stably maintained at the target temperature, as Figure 2 shown, the method described in this embodiment further includes: during the process of controlling the electric heater to perform heating operations in an alternating manner with the first preset power and the second preset power, detecting the current ambient temperature; determining whether the current ambient temperature is greater than the maximum value of the preset temperature range; when the current ambient temperature is greater than the maximum value of the preset temperature range, gradually increasing the second preset time period for which the electric heater performs heating with the second preset power until the current ambient temperature is within the preset temperature range.

[0061] Specifically, as Figure 2 shown, assuming the above-mentioned preset temperature range is [T 目标 -1, T 目标 +1], during the process of controlling the electric heater to perform heating operations in an alternating manner with the first preset power and the second preset power, when it is detected that the current ambient temperature is less than (T 目标 -1), that is, when T 环 <T 目标 -1, increase the high-grade operation time, and modify the control program to: first control the electric heater to heat at a higher first preset power for (a + X) minutes, and then control the electric heater to heat at a lower second preset power for b minutes. During this process, continuously monitor the current ambient temperature, and so on, and keep modifying until the current ambient temperature is within the preset temperature range to maintain temperature balance.

[0062] For example, first control the electric heater to operate at a high grade for 1 min, then switch to operate at a low grade for 1 min. After that, when it is detected that T 环 <T 目标 -1, increase the high-grade operation time, and modify the program to operate at a high grade for 2 min and then switch to operate at a low grade for 1 min. After that, if it is still detected that T 环 <T 目标If it is -1, the program is corrected to run at high gear for 3 minutes and then switch to low gear for 1 minute, and it is continuously corrected in this way until the current ambient temperature is within the above preset temperature range.

[0063] The logical principle of the above control is that when the ambient temperature is detected to be too low, by gradually increasing the high-gear operation time, the heat output of the electric heater is increased to raise the ambient temperature. Gradually increase the high-gear operation time to match the appropriate high-gear operation of (a + X) minutes and low-gear operation of b minutes.

[0064] Similarly, in the process of controlling the electric heater to heat in the way of alternating operation at the first preset power and the second preset power, when the current ambient temperature is detected to be greater than (T 目标 +1), that is, when T 环 > T 目标 +1, increase the low-gear operation time, and correct the control program to: first control the electric heater to heat at the higher first preset power for a minutes, and then control the electric heater to heat at the lower second preset power for (b + X) minutes. In this process, continuously monitor the current ambient temperature, and so on, and continuously correct until the current ambient temperature is within the preset temperature range to maintain temperature balance.

[0065] For example, first control the electric heater to run at high gear for 1 minute, and then switch to low gear for 1 minute. After detecting that T 环 > T 目标 +1, increase the low-gear operation time, and correct the program to run at high gear for 1 minute and then switch to low gear for 2 minutes. After that, if it is still detected that T 环 > T 目标 +1, then correct the program to run at high gear for 1 minute and then switch to low gear for 3 minutes, and continuously correct in this way until the current ambient temperature is within the above preset temperature range.

[0066] The logical principle of the above control is that when the ambient temperature is detected to be too high, by gradually increasing the low-gear operation time, the heat output of the electric heater is reduced to lower the ambient temperature. Gradually increase the low-gear operation time to match the appropriate high-gear operation of a minutes and low-gear operation of (b + X) minutes.

[0067] In the above correction process, by comparing the difference between the ambient temperature and the target temperature, the output power of the electric heater is continuously corrected through the internal self-correction program, so that the heat output of the electric heater reaches balance with the heat loss of the environment, and the stability of the ambient temperature can be effectively maintained.

[0068] In this embodiment, the value ranges of a and b can both be from 0 to 5 minutes, and the value range of X can be from 0 to 3 minutes. Of course, in practical applications, a, b, and X can be specifically set to other values according to actual needs, and this embodiment does not make specific limitations in this regard.

[0069] In this embodiment, the ambient temperature is detected in real time. Before the high and low gear switching is alternately executed, it has been detected that the current ambient temperature is equal to the target temperature. Detecting the ambient temperature again during the high and low gear switching process is to confirm whether the heat output of the high and low gear switching is sufficient to maintain the stability of the target temperature. If the power output cannot maintain the target temperature, corresponding step-by-step adjustments will be made. The effect of the power adjustment is not immediate but requires time to take effect. Therefore, in this embodiment, the relationship between the current ambient temperature and the target temperature will be determined again after the heating time corresponding to one high and low gear switching is completed to confirm whether it can maintain the stability of the ambient temperature.

[0070] The electric heater control method provided by the embodiment of the present invention obtains the target temperature set by the user. During the heating process of the electric heater, when it is detected that the current ambient temperature reaches the target temperature, the electric heater is controlled to perform a heating operation in a manner of alternately operating at a first preset power and a second preset power, so that the current ambient temperature is maintained at the above-mentioned target temperature. Since the first preset power is greater than the second preset power, the electric heater can maintain the ambient temperature at the target temperature by alternately operating at high and low powers, avoiding problems such as poor temperature stability, energy waste, and noise caused by the existing technology of frequently turning on and off to maintain the ambient temperature. It can be seen that the technical solution provided by the embodiment of the present invention can more accurately control the output temperature of the electric heater, make the ambient temperature more effectively maintained at the target temperature set by the user, and thus greatly improve the user experience.

[0075] In this embodiment, the control unit 202 controls the electric heater to perform a heating operation in an alternating manner at a first preset power and a second preset power, so as to maintain the current ambient temperature at the target temperature:

[0076] During the heating process of the electric heater, when it is detected that the current ambient temperature reaches the target temperature, the electric heater is controlled to alternately execute S1 and S2, so that the current ambient temperature is within a preset temperature range with the target temperature as the intermediate value:

[0077] S1: Heat at the first preset power for a first preset time period;

[0102] 3. During use, due to the temperature control requirements, there are frequent start and stop operations, and problems such as the generated noise affect the user experience.

[0103] The present invention has the following beneficial effects:

[0104] 1. By comparing the difference between the current ambient temperature and the target temperature, the output power is continuously corrected through an internal self-correction program, so that the heat output of the electric heater reaches an equilibrium with the heat loss of the environment, effectively maintaining the basic stability of the ambient temperature and improving the comfort experience of using the electric heater.

[0105] 2. There is no problem of frequent start and stop, the operation is stable, and the use experience is improved.
