[0002] With the development of smart home appliance technology, more and more smart home appliances have entered our lives, bringing great convenience to people. Take the heater as an example. In the cold winter, the heater can be used as a stable heat source to heat the room, giving people a warm and comfortable feeling.

[0003] The heating effect of a heater depends on the power of the heating element. At present, most heaters on the market are constant power heaters.

The heater has the following technical problems: the preset temperature threshold is a preset fixed value, and the heating is always controlled with the same preset temperature threshold under different ambient temperatures. This may result in: when the ambient temperature is high, the preset temperature threshold may be too high, the heat exchange rate of the heater is reduced, the output temperature is high, the heating is uncomfortable, and the surface temperature of the air outlet is high, posing a hidden danger of scalding; when the ambient temperature is low, the preset temperature threshold may be too low, the heat exchange rate is increased, but the wind temperature is low, and the output temperature and heat are insufficient to meet the heating needs; in addition, the temperature that each person feels comfortable at different operating temperatures is not the same.

[0051] Embodiment 1

[0052] Figure 1 The present invention provides a flow chart of a power control method for a temperature control device according to an embodiment of the present invention. The power control method for a temperature control device is applied to heating equipment including a temperature control device, such as an electric heater, an air conditioner, etc. Figure 1 As shown, a power control method for a temperature regulating device comprises the following steps:

[0053] Step 110, obtaining the current ambient temperature.

[0054] In this embodiment, the ambient temperature refers to the ambient temperature of a certain environmental area, wherein the environmental area may be a room area, such as a living room, bedroom, office, or other place where users are active.

[0055] In one embodiment, the ambient temperature is detected by a temperature sensing device provided in the heating device, wherein the temperature sensing device may be a temperature sensing bag, and the ambient temperature within a preset time interval is acquired by the temperature sensing bag. Optionally, the ambient temperature may be displayed by a display module provided in the heating device.

[0056] It is worth mentioning that in a specific area, such as an indoor environment area, the environmental stability of various places in the room is different due to the influence of air convection. In one embodiment, the ambient temperature specifically refers to the location where the air convection is the smallest. In other embodiments, the ambient temperature can also refer to the ambient temperature at a specific distance from the temperature adjustment device. This is not listed one by one in this embodiment.

[0057] In this embodiment, the temperature data obtained by the sensing package disposed at the location where the air convection of the temperature regulating device is the minimum is the current ambient temperature.

[0058] Step 120, based on the correspondence between the preset ambient temperature and the target temperature, determine the target temperature corresponding to the current ambient temperature; wherein the correspondence between the preset ambient temperature and the target temperature includes that when the ambient temperature is greater than or equal to the preset ambient temperature threshold, the target temperature is negatively correlated with the ambient temperature; when the ambient temperature is less than the preset ambient temperature threshold, the target temperature is within the deviation range of the preset comfort temperature.

[0059] In this embodiment, the target temperature corresponding to the current ambient temperature is determined based on the corresponding relationship between the preset ambient temperature and the target temperature.

[0060] Among them, due to individual differences in the sensitivity of the human body to temperature, for example, gender, age, health status, clothing, and regional environment will affect the determination of the target temperature. For example, at a certain ambient temperature, the target temperature of women is generally about 0.55 degrees Celsius higher than that of men; at a certain ambient temperature, the target temperature of people over 40 years old is generally about 0.55 degrees Celsius higher than that of young people under 40 years old. When multiple people use heating equipment in the same environment, they often quarrel because of their different target temperatures. In this embodiment, the above problem can be solved through the correspondence between the preset ambient temperature and the target temperature, so that the target temperature determined based on a certain ambient temperature can meet most requirements, and the target power is adjusted based on the target temperature, so that the heating equipment can be adjusted more accurately, and the output temperature is guaranteed to make the human body feel more comfortable.

[0061] In one embodiment, the correspondence between the preset ambient temperature and the target temperature may be pre-initialized in the controller of the heating device, or may be written into the heater controller in response to a user's pre-set operation.

[0062] In one embodiment, the corresponding relationship between the ambient temperature and the target temperature is determined by consulting literature.

[0063] In one embodiment, by sampling and counting the target temperatures of multiple people, the target temperatures of most people at various ambient temperatures are obtained, and then the corresponding relationship between the ambient temperature and the target temperature is determined.

[0064] In one embodiment, if Figure 2 As shown, the ambient temperature threshold is pre-set to 15°C, the comfort temperature is pre-set to 71°C, and the deviation range is ±1°C. Correspondingly, when the ambient temperature is greater than or equal to 15°C, the target temperature is negatively correlated with the ambient temperature; specifically, the target temperature and the ambient temperature are negatively correlated in a linear proportional relationship; when the ambient temperature is less than 15°C, the target temperature is within the deviation range of the comfort temperature, that is, the target temperature can be any value between 70°C and 72°C.

[0065] Because the human body itself is relatively constant temperature, the body surface temperature is about 37℃, and the body surface temperature will change with the change of ambient temperature. When the ambient temperature is higher, the body heat will evaporate from the skin surface in the form of sweat; when the ambient temperature is lower, the body will emit more heat, and at this time, heating equipment is needed to heat up the ambient temperature, reduce the rate of heat dissipation from the body, and maintain a relative balance between the body and the ambient temperature.

[0066] Among them, the comfortable temperature that the human body can feel is between 20℃ and 28℃. Below 20℃, the human body will feel uncomfortable and feel cold. Because the convection speed of hot air in a low-temperature environment will accelerate, it is difficult to maintain a stable temperature between 20℃ and 28℃ in a low-temperature environment, and a higher temperature value is required to compensate for the temperature loss. Therefore, for example, in an environment of 15℃ to 0℃, the target temperature is set to 70℃ to 75℃, and further, the target temperature is set to 70℃ to 72℃ to maintain the ambient temperature between 20℃ and 28℃; below 15℃, the target temperature needs to be set lower, which is negatively correlated with the ambient temperature, so as to maintain the ambient temperature between 20℃ and 28℃.

[0067] Of course, in other embodiments, the preset ambient temperature threshold and the preset comfort temperature value may be adaptively adjusted according to individual temperature perception, which is not limited herein.

[0068] Among them, compared with the prior art, the ambient temperature and the preset temperature threshold are obtained, and it is detected whether the ambient temperature is less than the preset temperature threshold. When the ambient temperature is less than the preset temperature threshold, the temperature regulating device is controlled to heat; when the ambient temperature is greater than the preset temperature threshold, the temperature regulating device is controlled to stop heating. The technical solution, because the preset temperature threshold is always consistent, cannot be adaptively adjusted according to the ambient temperature, resulting in the possibility that when the ambient temperature is low, the preset temperature threshold cannot reach the temperature that the human body feels comfortable, and the heating heat of the temperature regulating device is insufficient to meet the heating demand; or when the ambient temperature is high, the preset temperature threshold exceeds the temperature that the human body feels comfortable, the heating heat of the temperature regulating device is excessive, the human body feels uncomfortable, and energy is wasted. In addition, the surface temperature of the air outlet is prone to increase, posing a hidden danger of scalding.

[0069] In this embodiment, the target temperature corresponding to the ambient temperature is determined based on the ambient temperature, so that no matter whether the ambient temperature is high or low, the temperature finally reached by the temperature regulating device is always a temperature that the human body feels comfortable at, thereby meeting the heating needs of the personnel.

[0070] In one embodiment, the ambient temperature is acquired based on a preset time interval, so that the target temperature is adaptively adjusted according to the ambient temperature, and the output power of the temperature regulating device is continuously adjusted to achieve the purpose of adaptively adjusting the output power.

[0071] Step 130: determining a target power output by the temperature adjustment device based on the target temperature.

[0072] In this embodiment, Figure 3As shown, the target power of the temperature regulating device is determined based on the target temperature, so that when the ambient temperature is high, the output power is low to achieve energy saving and power saving; when the ambient temperature is low, the output power is high to provide sufficient heat for heating and achieve efficient use of electrical energy.

[0073] In one embodiment, the ambient temperature is acquired based on a preset time interval so that the output temperature is adaptively adjusted according to the ambient temperature. Furthermore, the target power of the temperature control device is adaptively adjusted so that the output power of the temperature control device is adjusted based on the target power to ensure that the output temperature of the temperature control device makes the human body feel more comfortable.

[0074] Compared with the prior art in which the target power of the temperature control device is calculated based on the ambient temperature, the target power of the temperature control device in this embodiment is calculated based on the target temperature, so that it is guided by the target power to ensure that the temperature output by the temperature control device of the heating equipment when it is working is a temperature that the human body feels comfortable.

[0075] Step 140: adjust the output power of the temperature adjustment device according to the target power.

[0076] In this embodiment, the output power of the temperature regulating device is adjusted according to the target power, so that the higher the ambient temperature, the lower the target power. Correspondingly, the output power of the temperature regulating device is reduced, and the output temperature based on the output power will also be reduced accordingly; conversely, the lower the ambient temperature, the higher the target power. Correspondingly, the output power of the temperature regulating device is increased, and the output temperature based on the output power will also be increased, so that different target temperatures can be achieved under different ambient temperatures by adjusting the target power.

[0077] In this embodiment, the target temperature is determined based on the acquired ambient temperature, and the output temperature of the temperature control device is adjusted according to the target temperature. On the one hand, the power is adjusted according to different ambient temperatures. When the ambient temperature is high, the output power is low to achieve the purpose of energy saving and power saving; when the ambient temperature is high, the output power is high to provide sufficient heat for heating and achieve efficient use of electric energy; on the other hand, the output temperature is determined by the ambient temperature, and the output temperature of the temperature control device is adjusted based on the target temperature, so that the temperature can be maintained at a certain output temperature, so that the output temperature is suitable and comfortable to meet the heating needs of most people.

[0078] Embodiment 2

[0079] Based on the above embodiment, the step of adjusting the output power of the temperature adjustment device according to the target power includes:

[0080] determining a target power duty cycle based on the target power;

[0081] The output power of the temperature adjustment device is adjusted based on the target power duty cycle.

[0082] The power duty cycle refers to the time ratio of the signal at a high level (or active state) in one cycle. Correspondingly, in this embodiment, the power duty cycle refers to the ratio of the power of the temperature adjustment device in one cycle, which determines the average power output of the power supply.

[0083] In this embodiment, the target power duty cycle is determined based on the target power, and the specific operating condition parameters of the temperature adjustment device are controlled by the target power duty cycle, thereby adjusting the output power of the temperature adjustment device.

[0084] In one embodiment, a suitable control switch is selected to control the heating of the temperature control device, for example, a high-power MOS tube, a thyristor and other related components. In the pulse width modulation (PWM) output by the controller, the high level and the low level are respectively used to control the on and off of the control switch, and then the target power duty cycle is determined based on the target power, so as to finally control the output power of the temperature control device, and realize stepless temperature control of the ambient temperature through the output power.

[0085] In this embodiment, the target power duty cycle is calculated based on the target temperature, and the target power of the temperature control device is controlled according to the target power duty cycle value, which has the effect of accurately controlling the heating power, improving energy utilization efficiency, enhancing heating comfort, and enhancing system stability and reliability.

[0086] Embodiment 3

[0087] Based on the above embodiment, the step of adjusting the output power of the temperature adjustment device based on the target power duty cycle includes:

[0088] Determining a duty cycle value of a control switch signal based on the target power duty cycle;

[0089] Based on the duty cycle value of the control switch signal, the corresponding control switch is controlled to output current to the temperature adjustment device during the conduction time, thereby adjusting the output power of the temperature adjustment device.

[0090] In this embodiment, in the pulse width modulation output by the controller, the duty cycle of the control switch signal is determined based on the target power duty cycle, that is, the control switch is controlled to output current to the temperature control device during the conduction time, so as to accurately control the average voltage or current applied to the temperature control device, and then accurately control the output power of the temperature control device.

[0091] In the heating equipment, the control switch is set in the internal cavity structure of the whole machine, generally at the cold air inlet end. During the temperature adjustment, that is, the power adjustment process, the control switch itself will repeatedly work to generate heat, and the heat exchange channel of the whole machine will assist in heat dissipation, so as to achieve stepless temperature adjustment and achieve a temperature control accuracy of ±1°C.

[0092] Embodiment 4

[0093] Based on the above embodiment, the target power is calculated as follows:

[0094] T=T0+P / P0*K

[0095] Among them, T is the target temperature; T0 is the current ambient temperature; P is the target power of the temperature control device; P0 is the rated power of the temperature control device; K is the target temperature coefficient, wherein the value of the target temperature coefficient is different at different current ambient temperatures.

[0096] In this embodiment, the corresponding target temperature is determined based on the ambient temperature. The target power of the temperature regulating device can be determined according to the ambient temperature, the target temperature, the rated power of the temperature regulating device, and the target temperature coefficient. The value of the target temperature coefficient is different at different current ambient temperatures.

[0097] Embodiment 5

[0098] Based on the above embodiment, the step of adjusting the output power of the temperature adjustment device according to the target power further includes:

[0099] The output power of the temperature regulating device is adjusted according to the target power until the temperature at a preset distance from the temperature regulating device is within an allowable error range of the target temperature.

[0100] In one embodiment, a target temperature corresponding to the current ambient temperature is determined based on the current ambient temperature, a target power of the temperature regulating device is determined based on the target temperature, and the output power of the temperature regulating device is adjusted according to the target power to adjust the output temperature of the temperature regulating device. As time goes by, the ambient temperature changes, the ambient temperature is continuously acquired, and a new target temperature corresponding to the current ambient temperature is re-determined, and a target power of the temperature regulating device is determined based on the new target temperature, and the output power of the temperature regulating device is adjusted according to the target power to adjust the output temperature of the temperature regulating device until the temperature at a preset distance from the temperature regulating device is within the allowable error range of the current target temperature.

[0101] In one embodiment, the preset distance from the temperature adjustment device is set to 30 cm, because 30 cm from the temperature adjustment device is a common distance for human body to keep warm. When the temperature 30 cm from the temperature adjustment device is within the allowable error range of the target temperature, the human body is in a relatively comfortable temperature state.

[0102] Embodiment 6
