As shown in FIG. 1 , a drying time estimating method according to an embodiment of the present invention includes the following steps:

S1, in the drying process, the temperature of the laundry to be dried is obtained by an infrared sensor in real time, wherein the infrared sensor may be a thermal infrared sensor (for example, a thermopile infrared sensor and a pyroelectric infrared sensor), and the temperature of the laundry is dried. It can be the surface temperature of the laundry. It should be noted that, in view of any object whose temperature is above absolute zero, infrared rays are radiated due to its own molecular motion. Therefore, the power signal radiated by the object can be converted into an electrical signal by an infrared sensor and processed by data processing to obtain an object.

Specifically, in the process of heating the clothes to be dried, the clothes to be dried will actively radiate infrared rays, and the heat sensitive element in the infrared sensor can sense the heat radiation emitted by the clothes to be dried and The signal is converted into a weak electrical signal, and then the weak electrical signal is subjected to signal amplification processing by the signal amplifying circuit to obtain the amplified thermoelectric signal, and the amplified electrical signal is transmitted to the analog to digital conversion device. Then, the electrical signal corresponding to the ambient temperature of the current infrared sensor is obtained by the thermistor in the infrared sensor and transmitted to the analog to digital conversion device. Therefore, in the process of performing analog-to-digital conversion on the amplified electrical signal, the analog-to-digital conversion device can perform temperature compensation according to an electrical signal corresponding to an ambient temperature of the current infrared sensor, thereby improving infrared temperature measurement. Precision.

Finally, the analog-to-digital conversion device converts the compensated temperature electrical signal into a digital signal and outputs it to a microprocessor of the dryer for data processing to obtain the temperature of the laundry to be dried and its temperature distribution. .

S2. Acquire the load of the laundry to be dried according to the temperature of the laundry to be dried obtained in real time, and/or the weight data detected by the load cell.

Wherein, the load amount of the laundry to be dried refers to the gross weight of the laundry to be dried after the washing is completed; the weight data refers to the data obtained by the load cell for detecting the dry laundry after the washing is completed.

Moisture content.

Optionally, there is no inevitable sequence between S2 and S3, and only the load and moisture content of the laundry to be dried can be obtained.

S4, estimating the drying time of the laundry to be dried according to the load amount and the moisture content of the laundry to be dried.

In an embodiment of the present invention, when the time for heating the laundry to be reached reaches the first preset time, the motor is stopped, and after the second preset time is left, the drying time of the laundry to be dried is performed. Estimated. The first preset time and the second preset time may be calibrated according to actual conditions.

Specifically, when the dryer is powered on and starts to work, the dryer will start to heat the dried laundry, and the infrared sensor inside the dry cleaning machine obtains the temperature of the laundry to be dried in real time, and records and saves it. When the heating time reaches the first preset time, the drum of the dryer can be controlled to stop running, and the second preset time is allowed to stand.

During the second preset time, the dryer can obtain the temperature distribution in the drum in real time through the infrared sensor, wherein the temperature distribution includes the temperature distribution of the laundry to be dried. After the second preset time, the dryer can control the drum to continue to operate, and generate a temperature change curve according to the temperature of the laundry to be dried obtained in the first preset time, and simultaneously acquire according to the second preset time. The temperature distribution within the drum generates a thermal image within the dryer to estimate the drying time of the laundry to be dried.

It should be noted that the dry cleaning machine described in this embodiment also needs to control the operation of the drum while heating the laundry to be dried to speed up the drying. However, while the dryer drum is running, the laundry to be dried is constantly moving irregularly within the drum of the dryer. If the temperature distribution in the drum is obtained in real time by the infrared sensor and the related thermal image map is generated, the thermal image map is not easy to reflect the distribution area of the laundry to be dried, that is, it is not suitable for calculating the space size of the combined drum to be baked. The volume of dry clothes. The dry cleaning machine described in this embodiment can control the motor to stop running only when the first heating time reaches the first preset time during the drying process, and wait for the second preset time to be acquired according to the real-time acquisition. The temperature of the dried laundry generates thermal image data, and during the drying (heating) process, the motor can be stopped without control.

In addition, in other embodiments of the present invention, in the second preset time, the dryer may generate a temperature change curve according to the temperature of the laundry to be dried acquired in the first preset time, and simultaneously pass the infrared sensor. The temperature distribution in the drum is obtained in real time, and a thermal image map in the dryer is generated according to the temperature distribution.

After obtaining the thermal image in the dryer, the dryer first determines the distribution area of the laundry to be dried in the drum according to the thermal image map, and then according to the space size of the drum, combined with the preset volume algorithm. The volume of the laundry to be dried can be calculated, wherein the preset volume algorithm can be calibrated according to actual conditions. Then the dry clothes can obtain the current running mode (for example, cotton and linen drying mode, chemical fiber drying mode or wool drying mode, etc.), and determine the material of the laundry to be dried according to the current operating mode, and according to the The volume and material of the laundry to be dried are calculated as the load of the laundry to be dried (ie, the weight of the laundry to be dried in a wet state after the washing is completed). It should be noted that, depending on the specific heat capacity of different materials (for example, the specific heat capacity of water is much larger than the specific heat capacity of various materials and metal), the temperature of wet clothes will be less than the temperature of the drum air outlet and the metal inner cylinder, for example, As shown in Fig. 3, the lower temperature region may be the area where the laundry is to be dried.

After obtaining the above temperature change curve, the clothes dryer can obtain the moisture content of the laundry to be dried according to different temperature change curves of the clothes having different water contents. It should be noted that since the specific heat capacity of water is much larger than that of various fabrics, the difference in materials can be ignored. Alternatively, the humidity of the laundry to be dried is detected in real time according to the humidity sensor, and the moisture content of the laundry to be dried is obtained.

When the dryer obtains the moisture content and the load amount of the laundry to be dried, the drying time of the laundry to be dried may be estimated according to a preset estimation algorithm. For example, calculating the weight of the water in the laundry to be dried according to the moisture content and the load amount of the laundry to be dried, and according to the weight of the water, the drying temperature of the dryer, the wind speed, the rotation speed, the inner cylinder volume, and the waiting One or more of the volume of the dried laundry, etc., predicts the drying time of the laundry to be dried.

The drying time of the dry clothes is provided to the user for the drying time of the updated laundry to be dried. It should be noted that the first preset time may be calibrated according to actual conditions, wherein the first preset time may be different during the whole process of heating the clothes dryer to be dried, for example, in the dry The first preset time may be 4 minutes before the clothes machine heats the dried clothes, and the first preset time may be changed to 2 minutes after the clothes dryer is heated for 12 minutes.

In summary, according to the drying time estimation method of the embodiment of the present invention, in the drying process, the temperature of the laundry to be dried is first obtained by the infrared sensor in real time, and then according to the temperature of the laundry to be dried obtained in real time, and/or The weight data detected by the load cell, the load amount of the laundry to be dried, and the moisture content of the laundry to be dried according to the temperature of the laundry to be dried obtained in real time, and/or the humidity data detected by the humidity sensor, Finally, according to the load amount and water content of the laundry to be dried, the drying time of the laundry to be dried is estimated.
