Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
The clothes dryer mainly comprises a box body, a clothes processing cylinder arranged in the box body, a driving motor for driving the clothes processing cylinder to rotate, and a drying fan capable of providing drying air (hot air) for the clothes processing cylinder, wherein a detection component capable of detecting environmental noise and a controller are also arranged in the clothes dryer, and if 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 member. In addition, in the present invention, the driving motor and the drying blower are separately provided and can each determine the respective rotational speeds in a decoupled manner.
Referring first to fig. 1, fig. 1 is a flowchart illustrating 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 dryer mainly includes the steps of:
s100, detecting environmental noise through a noise sensor.
S200, controlling at least the drying fan to run at a set fan rotating speed through a controller according to the environmental noise.
Through the arrangement, the effect of affecting the clothes drying performance of the clothes treatment equipment as little as possible on the basis of controllable noise is achieved, the use hearing comfort of a user when the clothes dryer is used is improved, and the user experience is improved.
Preferably, step S200 may include: the driving motor and the drying fan are controlled by the controller to operate at the set rotating speed, so that the clothes drying effect is ensured as much as possible by carrying out combined adjustment on the rotating speed of the driving motor on the basis of controllable noise. For example, in the case of a drying blower, the drying performance may be ensured or optimized by means or a combination of means of increasing the rotation speed of the driving motor, increasing the temperature of the drying gas, etc.
Referring to fig. 2, fig. 2 is a flowchart illustrating a method of controlling an operation of a dryer according to an embodiment of the present invention. As shown in fig. 2, in a preferred embodiment, the manner in which the driving motor and the drying blower operate at the set rotational speed may include:
s21: the change trend of the rotating speed of the drying fan is determined in a mode consistent with the high and low trend of the environmental noise. That is, if the detected environmental noise is low, the drying fan needs to be controlled to operate at a low rotation speed to achieve the purpose of generating low noise. Because the too high rotation speed of the driving motor also generates large noise and can cause the whole clothes dryer to shake, the rotation speed of the driving motor also needs to be reasonably set.
S22: the rotational speed of the driving motor is determined according to the laundry treatment level of the laundry treatment drum. For example, the laundry treatment level may be one or a combination of several parameters, such as laundry treatment time, weight of laundry to be treated, and material quality of laundry to be treated, or a value determined by one or several of them, such as a dimensionless value determined by a certain calculation formula or algorithm.
Through such setting, on the basis of realizing that the noise is controllable, ensure that the clothing in the clothing processing section of thick bamboo can be overturn by the in-process of being dried better to good dry clothing effect has been guaranteed.
Referring to fig. 3, fig. 3 is a schematic view of a drying program of a dryer according to an embodiment of the present invention. As shown in fig. 3, the process of determining a specific clothes drying mode by the clothes drying program mainly comprises the following steps:
s31: ambient noise is detected by a noise sensor.
S32, determining a clothes drying mode according to environmental noise, wherein the clothes dryer is preset with a plurality of clothes drying modes, and a driving motor and a drying fan in each clothes drying mode operate at a preset rotating speed.
Preferably, the drying mode includes a low noise mode, a general mode, and a quick mode.
If the ambient noise is not higher than the first noise threshold, it is determined to operate the dryer in a low noise mode. Specifically, the controller controls the drying fan to rotate at the first fan rotating speed and the driving motor to rotate at the first motor rotating speed, so that the control of the low-noise mode can be realized. Wherein the first motor speed is not less than the preset speed threshold, because a suitable motor speed can make the clothes fluffy so as to obtain a better clothes drying effect, and too small motor speed can make the clothes in the clothes treating cylinder not fully overturned, so that the clothes are not uniformly dried and wet, and the clothes drying effect is poor, for example, the phenomenon is more prominent when the first motor speed is less than 45rpm, and the first motor speed is preferably 48rpm. It will be appreciated that the first fan speed cannot be less than the preset speed threshold either, since a suitable amount of drying air will effectively shorten the drying time and improve the user experience, but too small a fan speed will result in an insufficient amount of drying air being fed into the laundry treatment drum, which may take a long time to dry the laundry in the laundry treatment drum, resulting in a very poor drying experience, such as is particularly the case when the first fan speed is less than 1800rpm, which may be 2100rpm, for example. For example, this mode is suitable for a scenario of a drying demand in a quieter environment, such as at night, where a user can accept a relatively long drying time.
The dryer is determined to be operated in the general mode, as in the case where the ambient noise is higher than the first noise threshold but not higher than the second noise threshold. Specifically, the controller controls the drying fan to operate at the second fan rotating speed and the driving motor to operate at the second motor rotating speed, so that the control of the normal mode, namely the medium noise mode, can be realized. The second fan rotating speed is greater than the first fan rotating speed, and the second motor rotating speed is greater than the first motor rotating speed. Preferably, the second motor speed is 50rpm and the second fan speed is 2400rpm. Through such setting, the amount of wind of the stoving wind of sending into the clothing processing section of thick bamboo is great when guaranteeing that the clothing of clothing processing section of thick bamboo can obtain abundant upset and fluffy, can be with the clothing with faster stoving, has effectively promoted user experience. For example, this mode is applicable to a scene of a clothes drying demand in daily life.
As in the case where the ambient noise is higher than the third noise threshold, it is determined to operate the dryer in the fast mode. Specifically, the controller controls the drying fan to rotate at the third fan rotating speed and the driving motor to rotate at the third motor rotating speed, so that the control of the fast mode, namely the high noise mode, can be realized. The third fan rotating speed is greater than the second fan rotating speed, and the third motor rotating speed is greater than the second motor rotating speed. It will be appreciated that the third motor speed cannot be greater than the preset threshold value, since a suitable motor speed can make the laundry fluffy for a better drying effect, and an excessive motor speed can generate a greater noise and can cause the dryer to shake as a whole, resulting in poor user experience, for example, in the case where the third motor speed is greater than 55rpm, which is more prominent, preferably the third motor speed is 52rpm. In addition, the third fan speed cannot be greater than the preset threshold value, because an amount of drying air effectively shortens the drying time to improve the user experience, and an excessive fan speed may cause excessive drying air to be fed into the laundry treating drum and generate a large noise to cause poor user experience, for example, in the case that the third fan speed is greater than 3000rpm, this phenomenon is more prominent, and preferably, the third fan speed is 2700rpm. For example, the mode is suitable for a scene requiring quick drying of clothes, and a user can tolerate high noise in the scene so as to achieve the purpose of quick drying of clothes.
Preferably, in order to ensure that the laundry in the laundry treating tub is sufficiently turned over and to prevent the dryer from shaking as a whole, the third motor rotational speed is equal to the second motor rotational speed and is the nominal rotational speed of the driving motor, i.e., the maximum operation rotational speed of the motor.
Through such setting, can be according to the combination operation of the rotational speed of noise sensor detection's environmental noise control driving motor and stoving fan to realize having the control of the many clothes drying modes of better clothes drying effect on the controllable basis of noise, promote user experience.
It will be appreciated that the above described ambient noise and/or display interfaces for the various drying modes may be provided on the user interface of the dryer and/or the panel of the remote control for the user to view in real time or to perform corresponding operations when necessary, such as after determining the drying mode, asking the user if to determine to perform the drying mode.
It will be appreciated that the specific values of the first noise threshold, the second noise threshold and the third noise threshold may be determined according to practical circumstances, such as according to previous experiments, analysis and combination of the tolerance of the user to noise. For example, the first noise threshold is 20 db, the second noise threshold is 30 db, the third noise threshold is 50, and the drying fan operates at the first fan speed when the noise is less than or equal to 20 db, i.e., the clothes drying mode is the low noise mode; when the noise is more than 20 db and less than or equal to 40 db, the drying fan operates at the second fan rotating speed, namely the clothes drying mode is a general mode; when the noise is greater than 40 dB, the drying fan runs at the third fan rotating speed, namely the clothes drying mode is a quick mode.
It should be noted that, the clothes drying program of the clothes dryer may adopt some or all of the above three modes, and those skilled in the art may add more clothes drying modes according to actual needs so as to adapt to more specific application occasions. For example, one of the modes is thinned, such as further thinning the fast mode into a fast low-noise mode, a fast medium-noise mode, a fast high-noise mode and the like, or a new clothes drying mode is added on the basis of the three modes.
In summary, in the preferred technical solution of the present invention, the driving motor and the drying blower can determine respective operation parameters in a manner of being out of association, and the drying blower is individually controlled according to the environmental noise detected by the noise sensor, so as to affect the drying performance of the laundry treatment apparatus as little as possible on the basis of the noise control. The drying fan and the driving motor are operated in a set combination of operation parameters so as to realize multi-mode control of the clothes dryer, thereby achieving the effect of drying clothes on the basis of controllable noise.
Thus far, the technical solution of the present invention has been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of protection of the present invention is not limited to these specific embodiments. Equivalent modifications and substitutions for related technical features may be made by those skilled in the art without departing from the principles of the present invention, and such modifications and substitutions will fall within the scope of the present invention.
