Among them, the temperature/humidity detection module includes a temperature/humidity sensor, a second MCU, and a wireless transmission module; the second MCU sends the value collected by the temperature/humidity sensor to the drying module 400 directly or after processing through the wireless transmission module.

The temperature/humidity sensor is at least one of a temperature sensor, a humidity sensor, or a temperature and humidity sensor. The temperature and humidity sensor integrates a temperature sensor and a humidity sensor, and can simultaneously collect the temperature value and the humidity value of the fabric to be dried.

The drying module 400 includes a first MCU and a heating module or a fan. The first MCU adjusts the power level of the heating module or the fan according to the data or processed data.

The wireless receiving module electrically connected to the first MCU in the drying module 400 can be used in conjunction with the wireless transmitting module connected to the second MCU in the temperature/humidity detection module to transmit the temperature and humidity collected by the temperature and humidity sensor value.

Of course, it should be understood that the wireless transmitting module of the temperature/humidity detection module can also be replaced by a wired transmission method.

In addition, the specific implementation manners of data transmission and processing between the temperature/humidity detection module and the drying module 400 may be multiple, and the specific implementation manners are as follows:

As shown in Figure 7, the first method is: the temperature/humidity sensor collects the temperature and humidity value, and directly sends it to the drying module 400 through the wireless signal transmission component of the second MCU and the wireless transmission module, and the wireless signal reception of the drying module 400 After the component receives the value, it is passed to the first MCU, and the first MCU performs data processing. The conversion success rate gear value is used to control the heating module or the fan to execute the corresponding power gear.

As shown in Figure 8, the second method is: the temperature/humidity sensor collects temperature and humidity values, the collected data is processed by the second MCU to convert the success rate gear value, and then the power gear value is sent to the drying module 400 The first MCU of the drying module 400 directly uses the power gear value processed by the second MCU to control the heating module or the fan to execute the corresponding power gear.

The drying method of the above drying system includes the following specific steps: the temperature/humidity sensor directly collects at least one of the temperature value and the humidity value of the fabric to be dried, and the value is used to adjust the drying module 400 to execute the corresponding power level Bit.

The specific setting form, shape, position, etc. of the drying module 400 are not limited by the present invention.

Specifically, as shown in FIG. 1, the drying module 400 may be arranged in the host component 100, and the heating module in the drying module 400 guides heat downward to the fabric to be dried on the drying rack through a fan.

As shown in FIG. 2, the drying module 400 may also be an independent bottom-mounted method, and the heating module in the drying module 400 guides heat upward to the upper fabric to be dried through a fan.

In addition, the drying module 400 can also be lifted or moved horizontally, rotated, and other forms; as shown in FIG. 3, the drying module 400 can be lifted and adjusted according to the length and material of the fabric to be dried. Specific height and location.

It should be noted that the specific power gear position of the drying module 400 may be the power gear position of the fan, such as the blowing wind speed, or the power gear position of the heating module, for example, the heating module consists of multiple smaller heating units. Composition, then you can choose to adjust the power level of the heating module by adjusting the number of heating units, or adjust the working current of the heating module to adjust the heating temperature.

The power gear of the heating module or fan is adjusted by intermittent startup, or the power gear of the heating module or fan is adjusted by controlling the power value. When the heating module or fan is actually running, it can be turned on intermittently through the setting of the program, such as turning on and running for 20 seconds to 1 minute every 20 seconds to 1 minute to meet the power adjustment. It can also be controlled by the input current and voltage of the fan or heating module to adjust the power value.

Moreover, the power gear value received or processed by the first MCU can further open and close the corresponding heating module or fan in addition to adjusting the gear position of the heating module or fan. For example, the heating module is turned off, and the natural wind blown by the fan is directly used to dry the fabric. The fabric can be clothes, cups, pillow cases, etc. When the drying module 400 is a bottom-mounted structure or a liftable structure, a fan may not be used, because the hot air generated by the heating module will naturally rise and dry the fabric to be dried above.

Furthermore, the temperature/humidity detection module includes a fixing part for fixing on the fabric to be dried, and the temperature/humidity sensor is installed on the fixing part. The temperature/humidity sensor is used to collect at least one value of the temperature value and the humidity value of the fabric to be dried, and the value is used for the drying module 400 to execute the corresponding power level. The temperature value or the humidity value can be collected, or the temperature value and the humidity value can be collected at the same time.

The fixing part acts on the fabric to be dried, and may be a hanger 01 or a clamping part 02 or an adhesion part 03 or a probe part for hanging the fabric to be dried.

As shown in Figure 4, a temperature/humidity sensor 001 is integrated on the hanger 01. When the fabric to be dried is hung on the hanger, the temperature/humidity sensor 001 detects the temperature and humidity value on the fabric to be dried, and receives it through the second MCU. Or processing is sent to the drying module 400 in a wireless or wired manner, and the drying module 400 executes the corresponding power gear.
