The noise of the clothes dryer usually lasts above 60 decibels during normal operation, especially when the environment where the clothes dryer is used is relatively quiet, which makes the user experience very poor. The noise of the clothes dryer mainly comes from the wind noise generated by the drying fan when it is running, so the noise can be reduced by reducing the wind speed. .

Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention. For example, although the present invention is described with a clothes dryer as an example, the laundry processing equipment can also be an integrated washing and drying machine or a dual-machine machine including a drying unit, and although the present invention uses the rotational speed as an operating parameter to describe the clothes The operation control method of processing equipment, but the operation parameters may include one or more of power, current, rotation speed, torque, or a combination of rotation speed, etc. Those skilled in the art can adjust it as needed to adapt to specific conditions. application occasions.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and should not be construed as indicating or implying relative importance.

The clothes dryer mainly includes a cabinet, a clothes processing cylinder arranged in the cabinet, a driving motor for driving the rotation of the clothes processing cylinder, and a drying fan capable of supplying drying air (hot air) to the clothes processing cylinder. The clothes dryer is also equipped with The detection component and the controller capable of detecting environmental noise, for example, the detection component is a noise sensor and is fixed above the box body. Wherein, the controller can control the operation control method of the clothes dryer according to the detection result of the detection component. In addition, in the present invention, the driving motor and the drying fan are set independently, and the two can respectively determine their respective rotational speeds in a disassociated manner.

Referring first to FIG. 1 , FIG. 1 is a first schematic flowchart of an operation control method of a clothes dryer according to an embodiment of the present invention. As shown in FIG. 1 , the operation control method of the clothes dryer mainly includes the following steps:

S100. Detect environmental noise by using a noise sensor.

S200. According to the ambient noise, at least the drying fan is controlled by the controller to run at the set fan speed.

Through such setting, the drying performance of the clothes processing equipment is affected as little as possible on the basis of controllable noise, which improves the hearing comfort of the user when using the clothes dryer, and improves the user experience.

Preferably, step S200 may include: controlling the driving motor and the drying fan to operate at a set rotational speed through the controller, so that the rotational speed of the driving motor can be adjusted as much as possible on the basis of controllable noise. Guaranteed drying effect. For example, in the case of a drying fan, the clothes drying performance can be guaranteed or optimized by increasing the rotating speed of the driving motor, increasing the temperature of the drying gas, or a combination of means.

Referring to FIG. 2 , FIG. 2 is a second schematic flowchart of an operation control method of a clothes dryer according to an embodiment of the present invention. As shown in Figure 2, in a preferred embodiment, the combined operation of the drive motor and the drying fan at a set speed may include:

S21: Determine the change trend of the rotation speed of the drying fan in a manner consistent with the high and low trends of the ambient noise. That is to say, if the detected ambient noise is relatively low, it is necessary to control the drying fan to operate at a relatively low speed to achieve the purpose of generating relatively low noise. Since the driving motor rotates too high, it will generate a lot of noise, and may cause the overall shaking of the clothes dryer. Therefore, the rotating speed of the driving motor also needs to be set reasonably.

S22: Determine the rotational speed of the driving motor according to the laundry processing level of the laundry processing drum. For example, the laundry treatment level can be one or a combination of parameters such as the laundry treatment time, the weight of the laundry to be treated, and the material of the laundry to be treated, or a value determined by one or more of them, For example, a dimensionless value determined by a certain calculation formula or algorithm.

Through such an arrangement, on the basis of realizing controllable noise, it is ensured that the clothes in the clothes processing cylinder can be well turned over during the drying process, thereby ensuring a good drying effect.

Referring to FIG. 3 , FIG. 3 is a schematic diagram of the principle of a drying program of a clothes dryer according to an embodiment of the present invention. As shown in Figure 3, the process of determining the specific drying method by the drying program mainly includes the following steps:

S31: Detect environmental noise through the noise sensor.

S32. Determine the drying mode according to the ambient noise, wherein the dryer is preset with multiple drying modes, and the drive motor and the drying fan in each drying mode operate at a combination of preset rotation speeds.

Preferably, the drying modes include a low noise mode, a general mode and a fast mode.

For example, in a situation where the ambient noise is not higher than the first noise threshold, it is determined to run the clothes dryer in a low-noise mode. Specifically, the control of the low-noise mode can be realized by controlling the drying fan to run at the first fan speed and the drive motor to run at the first motor speed through the controller. Wherein, the rotational speed of the first motor is not less than the preset rotational speed threshold. This is because an appropriate rotational speed of the motor can make the clothes fluffy so as to obtain a better drying effect, and an excessively small rotational speed of the motor may make the clothes in the clothes processing cylinder unable to Sufficient turning results in uneven drying and wetness of the clothes and poor drying effect. For example, this phenomenon is more prominent when the rotation speed of the first motor is less than 45 rpm. Preferably, the rotation speed of the first motor is 48 rpm. It is understandable that the speed of the first fan cannot be lower than the preset speed threshold. This is because an appropriate amount of drying air can effectively shorten the drying time and improve user experience, but too small a fan speed will cause clothes to be fed into the treatment drum. Insufficient drying air volume may take a long time to dry the clothes in the clothes processing drum, resulting in a very poor drying experience. For example, this phenomenon is more prominent when the first fan speed is less than 1800rpm. Ground, for example, the rotational speed of the first fan can be 2100rpm. For example, this mode is suitable for scenes where clothes are dried in a relatively quiet environment, such as at night, in which users can accept a relatively long drying time.

For example, in the case that the ambient noise is higher than the first noise threshold but not higher than the second noise threshold, it is determined to operate the clothes dryer in the normal mode. Specifically, by controlling the drying fan to run at the second fan speed and the drive motor to run at the second motor speed through the controller, the control of the normal mode, that is, the medium noise mode, can be realized. Wherein, the rotation speed of the second fan is greater than the rotation speed of the first fan, and the rotation speed of the second motor is higher than the rotation speed of the first motor. Preferably, the rotational speed of the second motor is 50 rpm, and the rotational speed of the second fan is 2400 rpm. Through such a setting, when the clothes in the clothes processing drum can be fully turned and fluffy, the air volume of the drying air sent into the clothes processing drum is larger, and the clothes can be dried at a faster speed, which effectively improves the user experience. . For example, this mode is suitable for the scene of drying clothes in daily life.

If the ambient noise is higher than the third noise threshold, it is determined to run the clothes dryer in the fast mode. Specifically, the controller controls the drying fan to run at the third fan speed and the driving motor to run at the third motor speed, so that the control of the fast mode, that is, the high noise mode, can be realized. Wherein, the rotation speed of the third fan is greater than the rotation speed of the second fan, and the rotation speed of the third motor is higher than the rotation speed of the second motor. It can be understood that the rotation speed of the third motor cannot be greater than the preset threshold, because an appropriate rotation speed of the motor can make the clothes fluffy so as to obtain a better drying effect, and an excessive rotation speed of the motor will generate greater noise and cause The overall shaking of the clothes dryer leads to poor user experience. For example, this phenomenon is more prominent when the rotation speed of the third motor is greater than 55 rpm. Preferably, the rotation speed of the third motor is 52 rpm. In addition, the speed of the third fan cannot be greater than the preset threshold. This is because an appropriate amount of drying air will effectively shorten the drying time and improve user experience. Excessive fan speed will cause too much drying air to be sent to the clothes for processing. There will be a lot of noise in the cylinder, which will lead to poor user experience. For example, when the rotation speed of the third fan is greater than 3000rpm, this phenomenon is more prominent. Preferably, the rotation speed of the third fan is 2700rpm. For example, this mode is suitable for the scene where clothes need to be dried quickly, and the user can tolerate high noise in order to achieve the purpose of drying clothes quickly.

Preferably, in order to ensure that the clothes in the laundry processing tub are fully turned over and avoid the overall shaking of the dryer, the speed of the third motor is equal to the speed of the second motor and both are the nominal speed of the driving motor, that is, the maximum operating speed of the motor.

Through such a setting, the combined operation of the driving motor and the speed of the drying fan can be controlled according to the environmental noise detected by the noise sensor, so as to realize the control of multiple drying modes with better drying effect on the basis of controllable noise, and improve user experience.

It can be understood that the display interface of the above-mentioned environmental noise and/or multiple drying modes can be set on the user interface of the dryer and/or on the panel of the remote control, so that the user can view it in real time or make corresponding adjustments when necessary. Operation, such as asking the user whether to confirm to execute the drying mode after determining the drying mode.

It can be understood that the specific values of the first noise threshold, the second noise threshold, and the third noise threshold can be determined according to actual conditions, such as based on previous tests and analysis, and in combination with the user's tolerance for noise. Exemplarily, the first noise threshold is 20 decibels, the second noise threshold is 30 decibels, and the third noise threshold is 50 decibels. When the noise is less than or equal to 20 decibels, the drying fan operates at the first fan speed, that is, the drying mode is Low noise mode; when the noise is greater than 20 decibels and less than or equal to 40 decibels, the drying fan operates at the second fan speed, that is, the drying mode is the general mode; when the noise is greater than 40 decibels, the drying fan operates at the third fan speed, that is, drying Clothes mode is fast mode.

It should be noted that the drying program of the clothes dryer can adopt some or all of the above three modes, and those skilled in the art can add more drying modes according to actual needs, so as to adapt to more specific applications. For example, refine one of the modes, such as further refining the fast mode into fast low noise mode, fast medium noise mode and fast high noise mode, etc., or add a new drying mode on the basis of the three modes, etc. .

To sum up, in the preferred technical solution of the present invention, the driving motor and the drying fan can determine their respective operating parameters in a disassociated manner, and control the drying fan separately according to the environmental noise detected by the noise sensor, so that the noise To affect the drying performance of the laundry treatment equipment as little as possible on a controlled basis. By making the drying blower and the drive motor run in combination with set operating parameters, multi-mode control of the clothes dryer can be realized, so that the effect of drying clothes can be taken into account on the basis of controllable noise.

So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings, but those skilled in the art will easily understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of the present invention.
