[0052] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0053] To address the risk of burns or scalds to hands or feet when the temperature of the electric heater's air outlet is unknown, a method is proposed that uses proximity sensing to display the current temperature range and adjusts the power output based on the real-time temperature, thus preventing this problem.

[0054] One of the core concepts of this invention is to use a proximity sensing detection module to determine the distance of a human body approaching the electric heater and the real-time detected temperature of the electric heater, and to use various methods such as display, voice, and buzzer to prompt the user whether it is safe to touch the heater, whether it is too hot or too cold, and to adjust the power level in real time.

[0055] Reference Figure 1 The diagram illustrates a flowchart of a control method for an electric heater according to an embodiment of the present invention. The method may specifically include the following steps:

[0056] Step 101: Obtain the distance of the user relative to the electric heater, the ambient temperature, and the air outlet temperature of the electric heater;

[0057] Electric heaters can typically be controlled in the following ways: manual control, where the power and temperature are adjusted manually using a knob or button; remote control, where the heater's on / off status, power, and temperature are controlled remotely using a remote control or smartphone app; and automatic control, where the heater's power and temperature are automatically adjusted using a built-in temperature sensor and control circuit to maintain the set temperature.

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

[0059] The proximity sensor module detects the distance and direction of a person approaching the heater, obtaining the user's distance relative to the heater. Temperature detection measures the ambient temperature and the temperature at the air outlet. Based on these temperatures, the microcontroller unit adjusts the heater's power. The display module uses different colors to indicate the current temperature at the air outlet in real time. The buzzer module and voice announcement module provide more intuitive verbal notifications about the heater's current temperature.

[0060] The proximity sensing module can use radar sensors to detect the distance between a person and an electric heater. For example, it can periodically detect the closest distance L between an "obstacle" within the radar's observation range and the radar. When L is detected to be less than a preset safety value A and continues to decrease, it can be assumed that someone is approaching. Alternatively, radar sensors with human and object recognition capabilities can be selected for more precise monitoring of human distance.

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

[0062] Step 102: Adjust 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: If the distance is greater than a first distance threshold and less than a second distance threshold, determine the target temperature based on the distance and the ambient temperature.

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

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

[0067] T = k × L + m × T0 + C

[0068] Where 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 burned. 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 warmth because the distance to the electric heater is too far. The second distance threshold can be any value between 1 meter and 2 meters. When the distance is greater than the first distance threshold but less than the second distance threshold, the user is in a safe distance range where they will not be burned but can still get warm. Within this distance, the distance to 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 gives the user the best heating experience.

[0070] Ambient temperature and distance from the user affect the degree of heat attenuation. To ensure relatively stable performance under different ambient temperatures and distances, the heating element power needs to be adjusted to match the corresponding heat attenuation parameters. The relationship between the target outlet temperature for effective and stable heating and variables such as ambient temperature and distance between the user and the heater is calculated using a PID (Proportional-Integral-Derivative) control algorithm. Simply put, it can be calculated using the above formulas based on the distance between the user and the heater and the ambient temperature.

[0071] Sub-step S12: If the temperature at the air outlet is lower than the target temperature, increase 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 have a better heating experience.

[0073] Sub-step S13: If the temperature at the air outlet is higher than the target temperature, reduce 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 have 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, thereby controlling the outlet temperature.

[0075] Using closed-loop control to regulate outlet temperature is a common automatic control strategy, especially in HVAC systems. The steps are roughly as follows: First, it's necessary to understand the system's dynamic characteristics, including sensors to measure the actual outlet temperature; actuators, typically heating elements such as electric heaters or heat pumps; and a controller responsible for adjusting the heating time duty cycle based on the difference between the actual and target temperatures, thereby increasing or decreasing the heating power to bring the outlet temperature to the target. Next, the target temperature is set, which can be determined based on user needs or environmental conditions. Temperature measurement uses temperature sensors (such as thermocouples, thermistors, or infrared sensors) to measure the outlet temperature in real time, and the error is calculated as: Error = Target Temperature - Actual Temperature. Then, the duty cycle is adjusted based on the magnitude and direction of the error: if the temperature is lower than the target temperature, the heating time duty cycle is increased to increase heating power; if the temperature is higher than the target temperature, the heating time duty cycle is decreased to reduce heating power.

[0076] The adjusted duty cycle is applied to the heating element, and the temperature at the air outlet is continuously monitored. The system constantly adjusts the duty cycle based on the difference between the actual and target temperatures, forming a closed-loop feedback system. In practical applications, the control parameters may need to be debugged and optimized to ensure that the system can operate stably under various operating conditions and achieve the best control effect.

[0077] By employing a closed-loop control method, the system can automatically adjust the duty cycle of the heating time to regulate 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] If 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 shall be reduced.

[0080] When the distance between the user and the electric heater is less than or equal to a first distance threshold, and the temperature of the air outlet is greater than or equal to a first preset temperature value, the user may be at risk of burns. 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 too high, and the user may be burned, the heating power of the electric heater will be reduced to lower the temperature of the air outlet.

[0081] Step 103: When the distance meets the preset distance condition, output a reminder message based on the air outlet temperature.

[0082] When the electric heater outputs a warning message, it means that the user has entered a scalding risk distance. At this time, the distance meets the preset condition, which means that the distance between the user and the electric heater is less than or equal to the first distance threshold. It is considered that the user is close to the heater, and the intelligent reminder mode is activated. Then, based on the actual air temperature of the air outlet, it determines whether there is a possibility of scalding and outputs a warning message 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 but 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 a user enters a distance range less than or equal to a first distance threshold, the intelligent reminder mode is activated, providing different reminders based on the real-time air outlet temperature. If the air outlet temperature is greater than or equal to a first preset temperature threshold (35-45 degrees Celsius), the user is at high risk of burns, and a first reminder message is output. If the air outlet temperature is less than the first preset temperature threshold but greater than or equal to a second preset temperature value (20-25 degrees Celsius), the user can use the heater safely without risking burns. If the air outlet temperature is less than the second preset temperature threshold (too low), a third reminder message is output, informing the user that it is safe to use the heater. The user can choose to manually adjust the temperature or wait for the heater to automatically adjust the frequency based on an algorithm to adjust the air outlet temperature. Furthermore, the first preset temperature threshold must be greater than the second preset temperature value to create a temperature gradient.

[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 but 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 a 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 based on the real-time air outlet temperature.

[0089] 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), the user is very likely to be burned. In this case, the display module will show red, indicating that the temperature is high and the air outlet should not be touched.

[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 warm up without being burned. The display module will then display yellow, indicating that the temperature is moderate and touchable, 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 air outlet temperature is lower than the second preset temperature threshold, the temperature is relatively low. The display module shows blue, indicating that the temperature is too low. The user can touch the device to manually adjust the temperature or wait for the heater to automatically adjust the frequency according to the algorithm to adjust the air outlet temperature.

[0092] In addition, the first preset temperature threshold is greater than the required second preset temperature value in order to form a temperature difference gradient.

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

[0094] When the distance meets the preset distance condition, if the temperature of the air outlet is greater than or equal to the first preset temperature threshold, the first prompt tone will be played through the buzzer module.

[0095] When a 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 based on 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 and 45 degrees Celsius), the user is very likely to be burned. The buzzer module will sound an alarm with a rapid and urgent "BIBIBIBIB" sound, indicating that there is a risk of getting close. If there is no alarm, it means that 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 message is broadcast through the voice module; if the air outlet temperature is less than the first preset temperature threshold but greater than or equal to the second preset temperature threshold, the second voice message is broadcast through the voice module; if the air outlet temperature is less than the second preset temperature threshold, the third voice message is broadcast through the voice module; the first preset temperature threshold is greater than the second preset temperature threshold.

[0099] When a 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 based on the real-time air outlet temperature.

[0100] 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 very likely to be burned. The voice module will give a voice prompt and announce "Master, the current temperature is too high and do not touch".

[0101] 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 without getting burned. The voice module will give a voice prompt and announce "Master, the current temperature is moderate, use with confidence" to inform 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.

[0102] When the air outlet temperature is lower than the second preset temperature threshold, the temperature is relatively low. The voice module will give a voice prompt, saying "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 is greater than the required second preset temperature value in order to form a temperature difference gradient.

[0104] This invention discloses a control method for an electric heater. The method involves acquiring the user's distance from the heater, the ambient temperature, and the heater's outlet temperature. Based on these parameters, the heating power of the heater is adjusted. Furthermore, when the distance meets a preset condition, a reminder message is output based on the outlet temperature. This allows the heater to sense the user's approach and automatically adjust its power, while also providing an intuitive surface temperature indicator. This makes the heater more user-friendly, eliminating the need for trial and error and reducing the risk of burns.

[0105] Reference Figure 3 The diagram illustrates a flowchart of another control method for an electric heater provided by an embodiment of the present invention. The method may specifically include the following steps:

[0106] The proximity sensor module detects the distance and direction of a person approaching the heater, while the temperature sensor detects the ambient temperature and the temperature at the air outlet. Based on these temperatures, the heater's power is intelligently controlled. When a person is detected at the air outlet or at a distance of 0cm to 10cm from device A, it is considered a close approach, and an intelligent alert mode is activated. The display module uses different colors to indicate the current temperature at the air outlet in real time. Both the buzzer module and the voice broadcast module provide more intuitive verbal notifications to the user about the heater's current temperature.

[0107] The display module indicates the current temperature readings, with different colors for each type of temperature. For example, red indicates a high temperature that should not be touched, yellow indicates a moderate temperature that can be touched, and blue indicates a low temperature that can be touched. At the same time, the electric heater automatically increases its power.

[0108] The system uses a voice prompt module to provide verbal prompts, such as "Master, the current temperature is too high, do not touch"; "Master, the current temperature is moderate, use with confidence"; and "Master, the current temperature is too low". The power is then automatically adjusted based on the user's experience.

[0109] The buzzer module provides a prompt: a rapid and urgent "BIBIBIBIB" sound indicates a risk of approaching; no sound indicates that it is safe to approach.
