[0052] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0053] In order to solve the problem that human hands or feet are at risk of scalding or burning when the current air outlet temperature of the electric heater is not clear, a method for controlling an electric heater is proposed which can sense human proximity and prompt the display of the current temperature range at the same time, and adjust the power according to the real-time temperature situation to avoid this problem.

[0054] One of the core concepts of an embodiment of the present invention is to use a proximity sensing detection module to determine the distance between the human body and the electric heater and the real-time detection temperature of the electric heater, and to use a variety of methods such as display, voice, and beep to prompt the user whether it is currently touchable, overheated or too cold, and adjust the power in real time.

[0055] Reference Figure 1 , shows a flow chart of a method for controlling an electric heater provided by an embodiment of the present invention, and the method may specifically include the following steps:

[0056] Step 101, obtaining the distance between the user and the electric heater, the ambient temperature, and the air outlet temperature of the electric heater;

[0057] Electric heaters are usually controlled in the following ways: manual control, manually adjusting the power and temperature of the electric heater through knobs or buttons; remote control, remotely controlling the switch, power and temperature of the electric heater through a remote control or smartphone application; automatic control, automatically adjusting the power and temperature of the electric heater through built-in temperature sensors and control circuits to maintain the set temperature.

[0058] Reference Figure 2 A schematic diagram of a control module of an electric heater provided by an embodiment of the present invention is shown, and the specific functions are as follows:

[0059] The proximity sensing module detects the distance and direction of the human body approaching the electric heater, and obtains the distance between the user and the electric heater. The temperature detection detects the current ambient temperature of the electric heater and the temperature of the air outlet. According to the temperature of the two, the microcontroller unit controls the power of the electric heater. The display module uses different colors to display the current temperature of the air outlet in real time. The buzzer module and the language broadcast module both use more intuitive language to remind the user of the current temperature of the electric heater.

[0060] The proximity sensing module can use radar sensors to detect the distance between the human body and the electric heater. For example, the closest distance L between the "obstacle" and the radar within the radar observation range is periodically detected. When it is detected that L is less than the preset safety value A and is constantly decreasing, it can be considered that someone is approaching. In addition, radar sensors with human and object recognition functions can be used to more accurately monitor the distance to the human body.

[0061] The sensors for detecting the ambient temperature and the air outlet temperature can be set as follows: place the temperature sensing package A on the outer shell of the electric heater and at the air inlet, and place the temperature sensing package B at the air outlet. The temperature detected by the temperature sensing package A is the ambient temperature, and the temperature detected by the temperature sensing package B is the air outlet temperature.

[0062] Step 102, adjusting the heating power of the electric heater according to the distance, the ambient temperature and the air outlet temperature;

[0063] In one embodiment, step 102 may include the following sub-steps:

[0064] Sub-step S11, when the distance is greater than a first distance threshold and less than a second distance threshold, determining a target temperature according to the distance and the ambient temperature;

[0065] In one embodiment, the sub-step S11 may include the following sub-steps:

[0066] The target temperature is calculated by the following formula:

[0067] T=k×L+m×T0+C

[0068] Wherein, T is the target temperature, L is the distance, T0 is the ambient temperature, k is the distance correction coefficient, m is the ambient temperature correction coefficient, and C is a constant.

[0069] When the distance between the user and the electric heater is less than or equal to the first distance threshold, the user is at risk of being scalded, and the value range of the first distance threshold can be any value between 10 cm and 20 cm; when the distance between the user and the electric heater is greater than the second distance threshold, the user will not be able to get direct heating experience because the distance to the electric heater is too far, and the value range of the second distance threshold can be any value between 1 meter and 2 meters; when the distance is greater than the first distance threshold and less than the second distance threshold, the user is in a distance range that will not cause scalding but can safely heat up. Within this distance, the distance of the user needs to be considered to adjust the air outlet temperature to obtain the most comfortable heating experience. The target temperature is the air outlet temperature that allows the user to experience the best heating experience.

[0070] The ambient temperature and the distance from the user will affect the degree of heat attenuation. To ensure that the user's use effect is relatively stable at different ambient temperatures and different use distances, it is necessary to adjust the power of the heating element to match the corresponding heat attenuation parameters. The relationship between the outlet target temperature and the ambient temperature, the distance between the user and the electric heater, and other variables that make the user's heating effect effective and stable is calculated using the PID (proportional-integral-differential) control algorithm. In simple terms, it can be calculated using the above formula relationship based on the distance between the user and the electric heater and the ambient temperature.

[0071] Sub-step S12, if the air outlet temperature is lower than the target temperature, increasing the heating power of the electric heater;

[0072] When the actual air outlet temperature is lower than the target temperature, the heating power of the electric heater needs to be increased to adjust the air outlet temperature to the target temperature so that users can get a better heating experience.

[0073] Sub-step S13, if the air outlet temperature is higher than the target temperature, reducing the heating power of the electric heater;

[0074] When the actual outlet temperature is higher than the target temperature, the heating power of the electric heater needs to be reduced to adjust the outlet temperature to the target temperature so that the user can get a better heating experience. In one embodiment, a closed-loop control method can be used to increase or decrease the heating frequency of the electric heater to control the outlet temperature.

[0075] Using a closed-loop control method to control the outlet temperature is a common automatic control strategy, especially in HVAC systems. The steps are as follows: First, it is necessary to understand the dynamic characteristics of the system, including sensors, which are used to measure the actual temperature of the outlet; actuators, which are usually heating elements such as electric heaters or heat pumps; controllers, which are responsible for adjusting the duty cycle of the heating time according to the difference between the actual temperature and the target temperature, and then increasing or decreasing the heating power to make the actual outlet temperature reach the target temperature. Next, set the target temperature to determine the target temperature of the outlet, which can be set according to user needs or environmental conditions. Temperature measurement uses a temperature sensor (such as a thermocouple, thermistor or infrared sensor) to measure the outlet temperature in real time, and calculate the error to calculate the error between the actual temperature and the target temperature: error = target temperature - actual temperature. Then adjust the duty cycle, and adjust the duty cycle of the heating time according to the size and direction of the error: if the temperature is lower than the target temperature, increase the duty cycle of the heating time to increase the heating power; if the temperature is higher than the target temperature, reduce the duty cycle of the heating time to reduce the heating power.

[0076] Apply the adjusted duty cycle to the heating element and continuously monitor the temperature of the air outlet. The system will continuously adjust the duty cycle according to the difference between the actual temperature and the target temperature, forming a closed-loop feedback system. In actual applications, it may be necessary to debug and optimize the control parameters to ensure that the system can operate stably under various working conditions and achieve the best control effect.

[0077] Through the closed-loop control method, the system can automatically adjust the duty cycle of the heating time to adjust the heating frequency, thereby maintaining the outlet temperature near the target value. This method not only improves the system's response speed and control accuracy, but also effectively saves energy.

[0078] In one embodiment, step 102 may further include:

[0079] When the distance is less than or equal to the first distance threshold and the air outlet temperature is greater than or equal to the first temperature threshold, the heating power of the electric heater is reduced.

[0080] When the distance between the user and the electric heater is less than or equal to the first distance threshold, and the air outlet temperature is greater than or equal to the first preset temperature value, the user may be at risk of being scalded. The first preset temperature value can be any value between 35 degrees Celsius and 45 degrees Celsius, that is, when the user is too close to the electric heater and the temperature of the electric heater is high, the user may be scalded, and the heating power of the electric heater is reduced to reduce the air outlet temperature.

[0081] Step 103: when the distance meets a preset distance condition, output a reminder message according to the air outlet temperature.

[0082] When the electric heater outputs a reminder message, it means that the user has entered the risk distance of scalding. At this time, the distance meets the preset conditions, that is, the distance between the user and the electric heater is less than or equal to the first distance threshold. The user is considered to be close to the heater, and the intelligent reminder mode is activated. Then, based on the actual air outlet temperature of the air outlet, it is determined whether there is a possibility of scalding and a reminder message is output to prevent the user from being scalded due to unknown temperature or accidental scalding.

[0083] In one embodiment, step 103 may include the following sub-steps:

[0084] When the distance meets the preset distance condition, if the air outlet temperature is greater than or equal to the first preset temperature threshold, a first reminder message is output; if the air outlet temperature is less than the first preset temperature threshold and greater than or equal to the second preset temperature threshold, a second reminder message is output; if the air outlet temperature is less than the second preset temperature threshold, a third reminder message is output; the first preset temperature threshold is greater than the second preset temperature threshold.

[0085] When the user enters a distance range less than or equal to the first distance threshold, the smart reminder mode is activated, and different reminders are given according to the real-time air outlet temperature. When the air outlet temperature is greater than or equal to the first preset temperature threshold, the first preset temperature value can be any value between 35 degrees Celsius and 45 degrees Celsius, and the user is likely to be scalded, then the first reminder message is output; when the air outlet temperature is less than the first preset temperature threshold and greater than or equal to the second preset temperature value, within this range, the user can keep warm but will not be scalded, then the second reminder message is output to inform the user that it is safe to use, and the second preset temperature value can be any value between 20 degrees Celsius and 25 degrees Celsius; when the air outlet temperature is less than the second preset temperature threshold, the temperature is too low, and the third reminder message is output to inform the user that the user can choose to manually adjust or wait for the electric heater to automatically adjust the frequency according to the algorithm to adjust the air outlet temperature. In addition, the first preset temperature threshold is greater than the required second preset temperature value, so that a temperature difference ladder can be formed.

[0086] In one embodiment, step 103 may further include the following sub-steps:

[0087] When the distance meets the preset distance condition, if the air outlet temperature is greater than or equal to the first preset temperature threshold, the first color is displayed through the display module; if the air outlet temperature is less than the first preset temperature threshold and greater than or equal to the second preset temperature threshold, the second color is displayed through the display module; if the air outlet temperature is less than the second preset temperature threshold, the third color is displayed through the display module; the first preset temperature threshold is greater than the second preset temperature threshold.

[0088] When the user enters a distance range less than or equal to the first distance threshold, the intelligent reminder mode is activated and different reminders are given according to the real-time air outlet temperature.

[0089] When the outlet temperature is greater than or equal to the first preset temperature threshold, which can be any value between 35 degrees Celsius and 45 degrees Celsius, the user is likely to be scalded, and the display module displays red, indicating that the temperature is high and cannot be touched by human hands;

[0090] When the air outlet temperature is less than the first preset temperature threshold and greater than or equal to the second preset temperature value, within this range, the user can keep warm but will not be burned, then the display module will display yellow, indicating that the temperature is moderate and can be touched, informing the user that it is safe to use. The second preset temperature value can be selected from any value between 20 degrees Celsius and 25 degrees Celsius;

[0091] When the outlet temperature is lower than the second preset temperature threshold, the temperature is relatively low and the display module displays blue, indicating that the temperature is low. The user can choose to adjust manually or wait for the electric heater to automatically adjust the frequency according to the algorithm to adjust the outlet temperature.

[0092] In addition, the first preset temperature threshold value needs to be greater than the second preset temperature value, so that a temperature difference step can be formed.

[0093] In one embodiment, step 103 may further include the following sub-steps:

[0094] When the distance meets the preset distance condition, if the air outlet temperature is greater than or equal to a first preset temperature threshold, a first prompt sound is broadcasted through the buzzer module.

[0095] When the user enters a distance range less than or equal to the first distance threshold, the intelligent reminder mode is activated and different reminders are given according to the real-time air outlet temperature.

[0096] When the air outlet temperature is greater than or equal to the first preset temperature threshold, which can be any value between 35 degrees Celsius and 45 degrees Celsius, the user is likely to be scalded. The buzzer module beeps and broadcasts "BIBIBIBIB" quickly and urgently, indicating that there is a risk of approaching; no broadcast means it is safe to approach.

[0097] In one embodiment, step 103 may further include the following sub-steps:

[0098] When the distance meets the preset distance condition, if the air outlet temperature is greater than or equal to the first preset temperature threshold, the first voice is broadcast through the voice module; if the air outlet temperature is less than the first preset temperature threshold and greater than or equal to the second preset temperature threshold, the second voice is broadcast through the voice module; if the air outlet temperature is less than the second preset temperature threshold, the third voice is broadcast through the voice module; the first preset temperature threshold is greater than the second preset temperature threshold.

[0099] When the user enters a distance range less than or equal to the first distance threshold, the intelligent reminder mode is activated and different reminders are given according to the real-time air outlet temperature.

[0100] When the outlet temperature is greater than or equal to the first preset temperature threshold, which can be any value between 35 degrees Celsius and 45 degrees Celsius, the user is likely to be scalded, and the voice module gives a voice prompt, saying "Master, the current temperature is too high, do not touch it";

[0101] When the outlet temperature is lower than the first preset temperature threshold and greater than or equal to the second preset temperature value, within this range, the user can keep warm without being burned, and the voice module gives a voice prompt, saying "Master, the current temperature is moderate, use it with confidence", informing the user that it is safe to use. The second preset temperature value can be any value between 20 degrees Celsius and 25 degrees Celsius;

[0102] When the air outlet temperature is lower than the second preset temperature threshold, the temperature is relatively low and the voice module gives a voice prompt, announcing "Master, the current temperature is too low". The user can choose to adjust it manually or wait for the electric heater to automatically adjust the frequency according to the algorithm to adjust the air outlet temperature.

[0103] In addition, the first preset temperature threshold value needs to be greater than the second preset temperature value, so that a temperature difference step can be formed.

[0104] The embodiment of the present invention introduces a control method for an electric heater, which obtains the distance between the user and the electric heater, the ambient temperature and the outlet temperature of the electric heater; adjusts the heating power of the electric heater according to the distance, ambient temperature and outlet temperature; and outputs a reminder message according to the outlet temperature when the distance meets the preset distance condition. The electric heater can sense the approach of the user and automatically adjust the power. At the same time, there is an intuitive surface temperature prompt, which makes it more intuitive for consumers to use. There is no need to touch it to test before knowing the current state, thus avoiding the risk of scalding.

[0105] Reference Figure 3 , shows a flowchart of another method for controlling an electric heater provided by an embodiment of the present invention, wherein the method may specifically include the following steps:

[0106] The proximity sensing module detects the distance and direction of the human body approaching the electric heater, and the temperature detection detects the current ambient temperature of the electric heater and the temperature of the air outlet. According to the temperature of the two, the power of the electric heater is intelligently controlled. When the distance between the human body and the air outlet or instrument A is detected (for example, A can be selected between 0cm and 10cm), it is considered that the human body is approaching and the intelligent prompt mode is activated. The display module uses different colors to display the current temperature of the air outlet in real time. The buzzer module and the language broadcast module both use more intuitive language to prompt the user of the current temperature of the electric heater.

[0107] The display module is used to differentiate and display the currently detected temperature conditions. For example, red temperature represents high temperature and cannot be touched by hands, yellow temperature represents moderate temperature and can be touched, blue temperature is low and can be touched, and the electric heater automatically increases the power.

[0108] Use the language announcement module for verbal prompts, such as "Master, the current temperature is too high, do not touch"; "Master, the current temperature is moderate, use it with confidence"; "Master, the current temperature is too low", and then automatically adjust the power according to the user experience of the human body.

[0109] Use the buzzer module to give a prompt. The sound of "BIBIBIBIB" is fast and urgent, indicating that it is risky to approach. If there is no sound, it means it is safe to approach.
