[0070] 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.

[0071] In the related art, in actual application, the power of the PTC heater cannot reach the power required for each specified gear, which causes the pin of the PTC heater to be insufficiently heated, thereby affecting the indoor temperature from reaching the theoretical temperature, and further resulting in a poor user experience. In order to solve the above technical problems, the present invention provides a temperature control method for a fan, first obtaining the desired temperature of the air inlet of the fan, and then obtaining the corresponding relationship between the temperature of the air inlet and the input current of the heating element, thereby determining the target input current of the heating element according to the desired temperature and the corresponding relationship between the temperature of the air inlet and the input current of the heating element, and finally adjusting the input current of the heating element to the target input current, so that the temperature of the air inlet reaches the desired temperature, thereby accurately determining the target input current of the heating element according to the desired temperature and the corresponding relationship between the temperature of the air inlet and the input current of the heating element, further making the temperature of the air inlet of the fan reach the desired temperature, and then making the indoor temperature reach the theoretical temperature, thereby improving the user experience.

[0072] Reference Figure 1 , shows a flow chart of the steps of a temperature control method of a fan provided by an embodiment of the present invention, and the method may specifically include the following steps:

[0073] Step 101, obtaining the expected temperature of the air inlet of the fan.

[0074] In an embodiment of the present invention, the fan may be a cooling and heating fan, and a control chip may be provided in the cooling and heating fan. When the fan starts to operate, the control chip may obtain a desired temperature of an air inlet of the fan.

[0075] In the present invention, the expected temperature may be the ambient temperature, that is, the temperature that the user expects the environment to reach, that is, the temperature of the air inlet of the fan.

[0076] In one embodiment, obtaining the expected temperature of the air inlet of the fan may include: obtaining the set temperature of the air inlet of the fan set by the user within a preset time period, and the usage frequency corresponding to the set temperature; determining the highest usage frequency among the usage frequencies corresponding to the set temperatures; determining the set temperature corresponding to the highest usage frequency; and determining the set temperature corresponding to the highest usage frequency as the expected temperature of the air inlet of the fan.

[0077] Specifically, for example, the preset time is two days, and the control chip can obtain the set temperature of the fan's air inlet set by the user within two days, and the usage frequency corresponding to the set temperature. For example, the set temperatures are 20°C, 22°C and 25°C, the usage frequency of 20°C is 1 time, the usage frequency of 22°C is 4 times, and the usage frequency of 25°C is 2 times. Then it can be determined that the highest usage frequency among the usage frequencies corresponding to the set temperatures is 4 times, and further it can be determined that the set temperature corresponding to the highest usage frequency of 4 times is 22°C, which means that the set temperature frequently used by the user within two days is 22°C, which also means that the user's most desired ambient temperature is 22°C, and also means that the expected temperature of the fan's air inlet is 22°C, so 22°C can be determined as the expected temperature of the fan's air inlet.

[0078] In one embodiment, determining the desired temperature of the air inlet may include: obtaining a set gear position for a heating element; obtaining a correspondence between the gear position of the heating element and the temperature of the air inlet; and determining the desired temperature of the air inlet of the fan based on the set gear position of the heating element and the correspondence between the gear position of the heating element and the temperature of the air inlet.

[0079] In the present invention, the heating element may be a PTC heater or other heating elements. The fan may be pre-set with a corresponding relationship between the gear position of the heating element and the temperature of the air inlet. For example, the first gear corresponds to a temperature of 20°C at the air inlet, the second gear corresponds to a temperature of 22°C at the air inlet, and the third gear corresponds to a temperature of 25°C at the air inlet. For example, if the fan control chip obtains that the setting gear position for the heating element is the second gear, then the desired temperature of the fan's air inlet may be determined to be 22°C based on the setting gear position of the heating element and the corresponding relationship between the gear position of the heating element and the temperature of the air inlet.

[0080] Step 102: Obtain the corresponding relationship between the temperature of the air inlet and the input current of the heating element.

[0081] In the embodiment of the present invention, after the control chip of the fan obtains the desired temperature of the air inlet of the fan, it can obtain the corresponding relationship between the temperature of the air inlet and the input current of the heating element.

[0082] In one embodiment, the correspondence between the temperature of the air inlet and the input current of the heating element can be determined in the following manner: obtain a first sampling temperature of the air inlet, and a second sampling temperature of the heating element and a sampling current of the heating element corresponding to the first sampling temperature of the air inlet, respectively; determine the correspondence between the temperature of the air inlet and the input current of the heating element based on the first sampling temperature of the air inlet, the second sampling temperature of the heating element and the sampling current of the heating element.

[0083] Specifically, before the fan is operated, the corresponding relationship between the temperature of the air inlet and the input current of the heating element can be determined in advance. Then, when the fan is operated, the corresponding input current of the heating element can be determined according to the temperature of the air inlet. By adjusting the input current of the heating element, the heating power of the heating element can be controlled, and the temperature of the air inlet can be made to reach the expected temperature. When determining the corresponding relationship between the temperature of the air inlet and the input current of the heating element, the resistance of the heating element can be adjusted, so that the temperature of the air inlet, the temperature of the heating element and the current of the heating element can be collected at different resistances. In this way, the first sampling temperature of the air inlet and the second sampling temperature of the heating element and the sampling current of the heating element corresponding to the first sampling temperature of the air inlet can be obtained, and then the corresponding relationship between the temperature of the air inlet and the input current of the heating element can be determined according to the first sampling temperature of the air inlet, the second sampling temperature of the heating element and the sampling current of the heating element.

[0084] In an embodiment of the present invention, obtaining a first sampling temperature of the air inlet, and a second sampling temperature of the heating element corresponding to the first sampling temperature of the air inlet, and a sampling current of the heating element, respectively, may include: obtaining the first sampling temperature of the air inlet, and a second sampling temperature of the heating element corresponding to the first sampling temperature of the air inlet, a sampling resistance of the heating element, and a sampling voltage of the heating element, respectively; and determining the sampling current of the heating element according to the sampling resistance of the heating element and the sampling voltage of the heating element.

[0085] Specifically, when collecting data, the first sampling temperature of the air inlet, as well as the second sampling temperature of the heating element, the sampling resistance of the heating element and the sampling voltage of the heating element corresponding to the first sampling temperature of the air inlet, can be obtained first. The sampling current of the heating element can be determined by the sampling resistance of the heating element and the sampling voltage of the heating element.

[0086] In one embodiment, determining the sampling current of the heating element based on the sampling resistance of the heating element and the sampling voltage of the heating element may include: converting the sampling voltage of the heating element into an electrical signal; processing the electrical signal through an amplifying circuit to obtain an amplified electrical signal; processing the amplified electrical signal through an analog-to-digital converter to obtain a digital signal; and determining the sampling current of the heating element based on the digital signal and the sampling resistance of the heating element.

[0087] Specifically, after obtaining the sampled voltage of the heating element, the sampled voltage can be converted into an electrical signal, and then the electrical signal can be amplified through an amplifier circuit to obtain an amplified electrical signal, and then the amplified electrical signal is sent to an A / D (Analog-to-Digital Converter) converter to convert the electrical signal into a digital signal, and finally the sampled current of the heating element is calculated according to the formula I=U / R. Among them, I is the sampled current of the heating element, U is the digital signal of the heating element, and R is the sampling resistance of the heating element.

[0088] In an embodiment of the present invention, determining the correspondence between the temperature of the air inlet and the input current of the heating element based on the first sampling temperature of the air inlet, the second sampling temperature of the heating element and the sampling current of the heating element may include: determining the correspondence between the temperature of the heating element and the temperature of the air inlet based on the first sampling temperature of the air inlet and the second sampling temperature of the heating element; determining the correspondence between the input current of the heating element and the temperature of the heating element based on the second sampling temperature of the heating element and the sampling current of the heating element; determining the correspondence between the temperature of the air inlet and the input current of the heating element based on the correspondence between the temperature of the heating element and the temperature of the air inlet and the correspondence between the input current of the heating element and the temperature of the heating element.

[0089] Specifically, first determine the first sampling temperature of the air inlet and the corresponding second sampling temperature of the thermal element, that is, when the heating element is the second sampling temperature, determine the first sampling temperature of the air inlet corresponding to this time, so that the corresponding relationship between the temperature of the heating element and the temperature of the air inlet can be determined, and then determine the second sampling temperature corresponding to the heating element when the heating element is the sampling current, so that the corresponding relationship between the input current of the heating element and the temperature of the heating element can be determined, and finally the two corresponding relationships are merged, that is, the corresponding relationship between the temperature of the air inlet and the input current of the heating element can be determined through the corresponding relationship between the temperature of the heating element and the temperature of the air inlet, and the corresponding relationship between the input current of the heating element and the temperature of the heating element.

[0090] Step 103: determining a target input current of the heating element according to the correspondence between the desired temperature and the temperature of the air inlet and the input current of the heating element.

[0091] In an embodiment of the present invention, after obtaining the correspondence between the temperature of the air inlet and the input current of the heating element, the control chip can determine the target input current of the heating element according to the expected temperature and the correspondence between the temperature of the air inlet and the input current of the heating element.

[0092] For example, the corresponding relationship between the temperature of the air inlet and the input current of the heating element is: when the temperature of the air inlet is 20°C, the corresponding input current of the heating element is 0.2A; when the temperature of the air inlet is 22°C, the corresponding input current of the heating element is 0.3A; when the temperature of the air inlet is 25°C, the corresponding input current of the heating element is 0.5A. When the desired temperature of the air inlet of the fan is 22°C, then according to the corresponding relationship between the temperature of the air inlet and the input current of the heating element, it can be determined that the input current of the heating element corresponding to 22°C is 0.3A. At this time, 0.3 can be determined as the target input current of the heating element.

[0093] Step 104: adjusting the input current of the heating element to the target input current so that the temperature of the air inlet reaches the desired temperature.

[0094] In an embodiment of the present invention, after determining the target input current of the heating element, the control chip can adjust the input current of the heating element. Specifically, the control chip can adjust the resistance value of the resistor of the heating element to adjust the input current of the heating element to the target input current, thereby making the heating power of the heating element reach the expected heating power and the temperature of the air inlet reach the expected temperature.

[0095] In order to better understand the embodiments of the present invention, Figure 2 and Figure 3 The embodiments of the present invention are described as follows. Figure 2 As shown, a flow chart of the steps of another temperature control method for a fan provided by an embodiment of the present invention is shown. The temperature of the air inlet, the temperature of the heating element and the voltage of the heating element are collected, the collected voltage of the heating element is processed by a method circuit to obtain a digital signal of the heating element, the current of the heating element corresponding to the digital signal of the heating element is determined, and the corresponding relationship between the temperature of the air inlet and the current of the heating element is determined according to the temperature of the air inlet, the temperature of the heating element and the current of the heating element, the desired temperature of the air inlet is obtained, and the target input current of the heating element is determined according to the desired temperature and the corresponding relationship between the temperature of the air inlet and the current of the heating element, and the input current of the heating element is adjusted and modulated to the target input current so that the temperature of the air inlet reaches the desired temperature.

[0096] like Figure 3As shown, a flow chart of the steps of another temperature control method for a fan provided by an embodiment of the present invention is shown. The temperature of the air inlet, the temperature of the heating element and the voltage of the heating element are collected, the corresponding relationship between the temperature of the air inlet and the input current of the heating element is determined, the desired temperature of the air inlet of the fan is determined, and the target input current of the heating element is determined according to the desired temperature and the corresponding relationship between the temperature of the air inlet and the input current of the heating element, and the input current of the heating element is adjusted to the target input current, so that the heating power of the heating element is adjusted accordingly, and the heating element generates heat accordingly, so that the temperature of the air inlet reaches the desired temperature.

[0097] In the embodiment of the present invention, the desired temperature of the air inlet of the fan is obtained; the corresponding relationship between the temperature of the air inlet and the input current of the heating element is obtained; the target input current of the heating element is determined according to the desired temperature and the corresponding relationship between the temperature of the air inlet and the input current of the heating element; the input current of the heating element is adjusted to the target input current so that the temperature of the air inlet reaches the desired temperature. Thus, according to the desired temperature and the corresponding relationship between the temperature of the air inlet and the input current of the heating element, the target input current of the heating element can be accurately determined, and the temperature of the air inlet of the fan can be further made to reach the desired temperature, and then the indoor temperature can reach the theoretical temperature, thereby improving the user experience.
