Description

Technical Field

[0001] This invention relates to the field of air heating technology, and more specifically, to a method and system for regulating and controlling the operation of a warm air blower. Background Technology

[0002] A warm air heater is a heating device composed of a blower, an electric motor, and air heating components. It is suitable for various types of workshops and can be used independently for heating or in conjunction with other heating equipment. With advancements in the design and functionality of warm air heaters, they have also become suitable for everyday heating in people's lives.

[0003] Depending on their size and application, space heaters can be categorized into small and large models. Small space heaters can be wall-mounted, saving floor space, while large space heaters are floor-standing and require limited floor area. Commonly used indoor space heaters in homes include floor-standing and desktop models. Due to the damp and cold winters in southern regions, some families require desktop space heaters for convenience in offices and schools.

[0004] Existing desktop heaters typically require manual control of fan speed and heating level. The air vents and airflow direction are fixed and cannot be adjusted to move objects. This results in a limited heating range and an inability to automatically adjust heating intensity according to changes in the surrounding environment, leading to unsatisfactory performance of desktop heaters. Summary of the Invention

[0025] Adjust the grille angle of the heater according to the heating angle to change the air delivery angle;

[0026] The required current of the blower motor of the heater is calculated based on the heating distance.

[0027] Determine whether the initial current of the air supply motor is greater than the required current;

[0028] When the initial current is greater than the required current, the heater will continue to operate at the initial current.

[0029] When the initial current is less than the required current, the current of the blower motor is adjusted to the required current.

[0068] Figure 1 A flowchart of a heater operation adjustment and control method according to an embodiment of the present invention is shown. The heater operation adjustment and control method includes:

[0069] S100: Identifies target objects within the field of view based on a preset target object dataset, wherein the target objects include hands, upper arms, and faces. To increase the accuracy of the heater in identifying target objects, images of different forms of target objects can be acquired and saved in advance, such as outstretched hands, bent hands, and clenched fists, forming datasets for both hands or one hand. Similarly, an upper arm dataset corresponding to the upper arm and a face dataset corresponding to the face can be created. Depending on individual needs, the heater can be set to blow warm air towards the hands, upper arms, chest, or face. When different target objects are specified for the heater, the corresponding target object dataset is invoked at any time. By comparing the target objects within the field of view with the data in the dataset, the type of target object is identified. For example, when the target object of the heater is set to a hand, a camera installed on the heater can capture all items within its field of view, and then the captured images are compared and analyzed with the hand dataset to determine if a hand is present in the captured images. Image recognition technology can be used during the identification process, typically by taking pictures with a camera and then using software to process the images based on grayscale differences to identify useful information. In this embodiment, the heater is applied to a desktop setting, primarily for heating the upper body. To provide targeted heating for different objects, the objects are further categorized into hands, upper arms, and face. Of course, the desktop heater can also heat the legs; leg data can be added to the dataset. Furthermore, to avoid the heater recognizing unnecessary objects, its field of view is limited to the desktop. When the heater detects the edge of the desktop, objects outside that edge will not be recognized.

[0070] S200: Based on the identified target object's location information, calculate the heating distance between the target object and the heater. Since the distance between the heater and the target object affects the user experience, the heater's operating parameters need to be adjusted according to the heating distance. After the target object has been identified, since the heater's camera only takes close-up photos of the desktop, the camera's focal length can be fixed. With a fixed focal length, a large number of photos can be used for training to obtain the correspondence between the object's size in the photo and the distance between the object and the camera. Alternatively, based on experience, a custom correspondence between the object's size in the photo and its distance from the camera (i.e., the heater) can be defined. Furthermore, based on the target object's height in the image, the same method described above is used to obtain the correspondence between the target object's height in the photo and its actual height. After knowing the distance between the target object and the heater, as well as the height of the target object, we can determine the location of the target object. Since the air outlet of the heater also has a certain height, we can use trigonometric functions to calculate the distance from the air outlet of the heater to the target object (i.e., the heating distance), as well as the angle between the line connecting the two and the horizontal direction (i.e., the calculated heating angle that needs to be achieved, which is the air delivery angle that the air outlet of the heater needs to be adjusted to achieve).

[0071] S300: Adjust the fan speed and airflow angle of the heater based on the heating distance and the initial settings of the heater. When the heating distance is long, more heat is lost when it reaches the user's body surface. In this case, it is necessary to increase the speed and angle of heat transfer to allow the heat to reach the target location faster and more accurately, reducing heat loss and allowing the user to feel more heat. This also enhances the heater's responsiveness and improves the user experience. The airflow angle can be adjusted based on the calculated heating angle; simply adjust the airflow angle to the calculated heating angle.

[0072] S400: Real-time monitoring of the temperature of the target object and the ambient temperature around it. When the ambient temperature is low, the heater needs to provide more heat to counteract the cold air and increase user comfort. Therefore, the heating level of the heater needs to be adjusted adaptively according to the ambient temperature. Temperature monitoring of the target object and the environment can be performed using a non-contact temperature measurement unit installed in the heater (e.g., a built-in non-contact thermometer, a non-contact infrared thermometer, etc.).

[0073] S500: Adjust the heating level of the heater based on the temperature of the target object, the ambient temperature, and the initial heating level of the heater. Since the user manually sets the heating level at the initial stage of operation, providing a comfortable experience, but the ambient temperature changes constantly, even within a day, the heater can adaptively adjust its heating level based on the surrounding environment. This ensures the user consistently experiences a comfortable temperature, avoids unnecessary energy waste due to excessively high heating levels, enhances the heater's self-regulation capability, improves its environmental adaptability, and ultimately improves its performance. In addition, it is necessary to monitor the temperature of the target object in real time, because the surface temperature of the target object can directly indicate whether the user feels the temperature rise after using the heater for a period of time, and whether the user no longer feels cold. For example, when the surface temperature of the target object is 36℃-36.2℃, it means that the user's body temperature is not high, and they may feel cold at this time. This suggests that the user is not affected by the heating effect of the heater, and the heating level of the heater can be appropriately increased. When the surface temperature of the target object reaches between 36.3℃ and 36.6℃, it means that the ambient temperature is comfortable. When the surface temperature of the target object exceeds 36.6℃, the heating level of the heater can be appropriately reduced, or an alarm can be issued.

[0074] In this embodiment, by identifying the location of the target object, the heating distance of the heater is analyzed and calculated. Then, based on the heating distance and the initial setting parameters of the heater, the wind speed and air delivery angle of the heater are adjusted, so that heat reaches the target object location faster and more accurately, reducing heat loss and allowing the user to feel more heat. At the same time, the heater's responsiveness is enhanced, improving the user experience. Furthermore, the temperature of the target object and the ambient temperature around it are monitored in real time. Based on the temperature of the target object, the ambient temperature, and the initial heating level of the heater, the heating level of the heater is adjusted to ensure a comfortable ambient temperature for the user. This also avoids unnecessary energy waste caused by excessively high heating levels, improves the heater's self-regulation capability, enhances its environmental adaptability, and improves its performance.

[0075] In one embodiment of the present invention, identifying target objects within the field of view based on a preset target object dataset includes:

[0076] The specified target object is set for the heater, and all target objects within the field of view are identified according to the preset target object dataset;

[0077] When the number of target objects within the field of view is greater than a preset value, one or more target objects that first appear within the field of view are selected as target objects, or the target object that has appeared within the field of view for the longest time is selected as target object, and the information of the remaining target objects is discarded.

[0078] The above steps further specifically include: when the target object of the heater is set to a hand, identifying the hand within the field of view;

[0079] When the number of hands within the field of vision is greater than two, the first two hands appearing within the field of vision are taken as the target objects, and the information of the remaining hands is discarded. Because when studying or working at a desk, multiple people's hands may appear within the field of vision, such as when parents are tutoring their children, the child's hands are frequently on the desk, while the parent's hands are only occasionally present. Therefore, relying solely on the student's hands as the primary identification target is not feasible, as the size difference between adults and children is not significant by the time students reach middle or high school. Therefore, it is also necessary to confirm the target object based on the order in which the hands appear within the field of vision or the duration of their presence. For example, the hand that appears for the longest time within the field of vision is taken as the target object. To transfer most of the heat to the student, only the student's two hands can be taken as the primary target objects.

[0080] When the target object of the heater is set as the upper arm, the upper arm within the field of view is identified;

[0081] When the number of upper arms within the field of vision is greater than two, the first two upper arms appearing within the field of vision are used as the target objects, and the information of the remaining upper arms is discarded. Similar to the identification and determination of both hands, the identification of both arms is also done in this way. Since the student is always within the field of vision and rarely moves, the upper arm appearing for the first time within the field of vision is used as the target object. Even if the student occasionally moves, the parent's upper arm may be identified as the target object, but compared to the time the student spends at the desk, the parent's time at the desk is shorter, and during this shorter time, the parent is generally close to the student, guiding their studies. Therefore, during this period, the impact on the student's experience using the heater is minimal. After the parent leaves, the heater will again identify the student's upper arm as the target object.

[0082] When the target object of the heater is set to a face, the face within the field of view is identified;

[0083] When the number of faces appearing within the field of view is greater than one, the face that first appears within the field of view is taken as the target object, or based on historical data, the face that appears for the longest time within the field of view is taken as the target object. Similarly, for face shape recognition, since there are many facial features and significant differences, in addition to the above recognition methods, facial recognition technology can be combined to enhance the accuracy of recognition.

[0084] In one embodiment of the present invention, calculating the heating distance between the target object and the heater based on the identified location information of the target object includes:

[0085] Once the positions of the hands or arms within the field of view are identified, the center position between the hands or arms is analyzed. If only one hand is heated, the other hand will receive less heat, and directly blowing heat on one hand will make it feel overheated. Therefore, heating the area between the two hands is a better approach. By directing heat between the hands, the heat is released from the center outwards, heating not only the hands on both sides but also the chest. Furthermore, while the heat is not directly blowing on one hand, it passes near or above it, radiating heat to that hand as well, increasing heat utilization. Therefore, to better heat the dominant hand, the heater can be placed on the side of the dominant hand, allowing it to receive double heating and preventing the dominant hand from being exposed to the air and feeling cold during prolonged use.

[0086] Calculate the horizontal and vertical distances between the center position of the hands or arms and the heater to obtain the heating distance and heating angle. Using trigonometric functions and the Pythagorean theorem, the heating distance and heating angle can be calculated from the horizontal and vertical distances.

[0087] Alternatively, if only the position of a single hand or arm within the field of view is identified, the center position of that hand or arm can be analyzed. Since students sometimes don't place both hands on the desk while doing homework, even when only one hand is identified, the center position of that hand should be taken to optimize heating.

[0088] Calculate the horizontal and vertical distances between the center position of the single hand or arm and the heater to obtain the heating distance and heating angle;

[0089] Alternatively, once the position of a face within the field of view is identified, the horizontal and vertical distances between the face and the heater can be analyzed to obtain the heating distance and heating angle. Since faces are relatively concentrated, and heaters are often placed on one side of a table (the user's side), the heater typically identifies a profile of the face. Therefore, it is only necessary to calculate the heating distance and heating angle between the profile and the heater.

[0090] In one embodiment of the present invention, before adjusting the wind speed and air delivery angle of the heater according to the heating distance and the initial setting parameters of the heater, the heater operation adjustment and control method further includes:

[0091] When the target object of the heater is set as a hand or upper arm, the humidification function of the heater is turned off.

[0092] When the target object of the heater is set to the face, the humidification function of the heater is turned on. To avoid facial dehydration caused by prolonged use of the heater, the humidification function can be turned on when the target object of the heater is the face. This controls the humidification pump in the humidification chamber to pump the water mist from the humidification chamber out of the heater and spray the pumped water mist into the surrounding environment instead of blowing it directly onto the user's face, thus reducing user discomfort.

[0093] In one embodiment of the present invention, adjusting the wind speed and air delivery angle of the heater according to the heating distance and the initial setting parameters of the heater includes:

[0094] The angle of the heater's grille is adjusted according to the heating angle to change the air delivery angle. A grille motor is provided to adjust the grille angle. When adjustment is needed, the grille motor is controlled to rotate a certain angle or for a specified time. Using a stepper motor allows for more precise control of the grille's rotation to a specified angle, resulting in more accurate rotation.

[0095] The required current of the blower motor for the heater is calculated based on the heating distance. When the heating distance is large, the blower motor requires a larger current, which increases the rotation speed of the blades and the airflow, allowing heat to reach the user's body surface more quickly.

[0096] Determine whether the initial current of the air supply motor is greater than the required current;

[0097] When the initial current is greater than the required current, the heater will continue to operate at the initial current.

[0098] When the initial current is less than the required current, the current of the air supply motor is adjusted to the required current. Since the fan speed and grille angle are set when the user turns on the heater, these initial parameters are used as the initial parameters. Based on these initial parameters, the operating parameters of the heater are adjusted to match the user's needs.

[0099] In one embodiment of the present invention, after adjusting the grille angle of the heater according to the heating angle and changing the air supply angle, the heater operation adjustment and control method further includes:

[0100] When the grille angle is adjusted to its limit position, the difference between the heating angle and the air supply angle is calculated.

[0101] When the difference is greater than zero, the base motor of the heater is powered on.

[0102] The base motor is controlled to rotate based on the difference to bring the air delivery angle to the heating angle. Adjusting the grille is a fine-tuning process, allowing for precise adjustments to the air delivery angle. However, when the grille's adjustment angle reaches its limit, adjustments can be made via the heater's base. The heater's base can be configured to be adjustable both horizontally and vertically. When the air delivery angle needs adjustment, the horizontal and vertical adjustment motors can be coordinated to change the base's angle, allowing it to rotate and achieve the desired air delivery angle.

[0103] In one embodiment of the present invention, adjusting the wind speed and air delivery angle of the heater according to the heating distance and the initial setting parameters of the heater further includes:

[0104] When the heating distance is greater than the first distance and less than the second distance, adjust the size of the air outlet of the heater to the first opening degree;

[0105] When the heating distance is greater than the second distance, adjust the size of the air outlet of the heater to the second opening. In order to increase the air supply speed and reduce the large-area heat loss, the air outlet can also be reduced to send the heat out from a smaller outlet, thus concentrating the heat and reducing the outer area of ​​the heat dissipation. In addition, reducing the air outlet can increase the air supply speed under the same air supply pressure, so that the heat reaches the user's surface more quickly.

[0106] In one embodiment of the present invention, adjusting the heating level of the heater based on the temperature of the target object, the ambient temperature, and the initial heating level of the heater includes:

[0107] When the ambient temperature within the field of view is lower than the first temperature, the heating level of the heater is increased by one level based on the initial heating level of the heater; the first temperature is a preset temperature value to ensure that the ambient temperature is not too low.

[0108] Analyze the temperature difference between the ambient temperature and the first temperature; when the ambient temperature drops to the first temperature, it will take a certain amount of time for the ambient temperature to rise after the heating level is increased by one level. Therefore, a waiting time can be set based on the size of the temperature difference. The larger the temperature difference, the longer the waiting time can be set.

[0109] Based on the temperature difference and the preset unit time, the allowable warming time is obtained, and heating is provided according to the allowed warming time. The preset unit time refers to the waiting time required when the temperature difference is one degree, for example, 2 minutes when the temperature difference is one degree. The allowable warming time is the total waiting time.

[0110] After the heating level is increased by one level, a countdown is performed based on the allowed temperature recovery time. When the countdown ends, it is determined whether the ambient temperature is greater than the first temperature.

[0111] If the ambient temperature is still lower than the first temperature, increase the heating level of the heater by one level and monitor whether the temperature of the target object increases. When the waiting time ends, the ambient temperature needs to be checked again. If the ambient temperature is still lower than the first temperature, it indicates that the temperature rise is too slow, and the heating level can be increased again. After these two adjustments, no further adjustments to the temperature level are necessary, because the heating level of the heater is limited and cannot be increased indefinitely. At this point, it is only necessary to monitor the temperature of the target object. As long as the temperature of the target object increases, it indicates that increasing the heating level is effective.

[0112] When the temperature of the target object increases, the current heating level is maintained;

[0113] When the temperature of the target object does not increase, an alarm message is generated to remind the user to inspect the heater. The ambient temperature and the temperature of the target object can be obtained by measuring the infrared temperature measurement component.

[0114] In one embodiment of the present invention, after adjusting the wind speed and air delivery angle of the heater according to the heating distance and the initial setting parameters of the heater, the heater operation adjustment and control method further includes:

[0115] The temperature of the grille of the heater is obtained by a temperature sensor installed at the grille. During the long heating process of the heater, the temperature of the grille will gradually increase. Since the grille temperature is too high, it may burn the user and melt other non-metallic parts in contact with the grille. Therefore, in addition to improving the heating level of the heater, it is also necessary to ensure that the temperature of the grille does not get too high.

[0116] When the temperature of the grille is greater than the second temperature, the cooling water pump located in the humidification chamber of the heater is controlled to work, and the water in the humidification chamber is pumped to the water channel embedded in the grille; the water channel is set inside the grille, and when the temperature is too high, the grille can be cooled by water cooling.

[0117] Monitor the water temperature inside the humidification chamber;
