Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
Embodiments of a condensation type clothes drying apparatus according to the present invention will be described with reference to the accompanying drawings.
(1) Embodiments of condensing clothes drying apparatus
Referring to fig. 1 to 6, the condensing type clothes drying apparatus provided in the present embodiment includes a drum 10, a condensing unit, a condensing duct 20, a fan 30, a lint collector 40, a connecting duct 50, a turbidity sensor, and a controller.
As shown in fig. 1, a drum 10 serves to receive laundry to be dried. As shown in fig. 2 and 3, a condensing device is disposed in the condensing air duct 20 for condensing air in the condensing air duct 20; one end of the connecting pipe 50 is communicated with the condensing air duct 20 (in fig. 3, the connecting pipe 50 is communicated with the condensing air duct 20 at a position close to the air outlet 21 of the condensing air duct 20, that is, a communication position of the condensing air duct 20 and the drum 10), and the other end is connected with the lint collector 40, specifically, connected with the lint inlet 42 of the lint collector 40, as shown in fig. 5. The fan 30 is communicated with the connecting pipeline 50 and is used for forming airflow from the condensation air duct 20 to the flock collector 40 in the connecting pipeline 50.
Under the action of the fan 30, an air flow from the condensation air duct 20 to the lint collector 40 is formed in the connecting duct 50, and under the action of the air flow, the end of the connecting duct 50 connected with the condensation air duct 20 can generate a suction effect on the condensation air duct 20. Under the suction effect, the lint and other substances generated by the condensing type clothes drying device during the clothes drying process and accumulated in the condensing air duct 20 are sucked out of the condensing air duct 20, enter the connecting duct 50, flow toward the lint collector 40 under the action of the air flow in the connecting duct 50, and finally enter and are collected in the lint collector 40. Through the process, the flock in the condensation air duct 20 is transferred and conveyed into the flock collector 40, on one hand, substances such as flock and the like do not exist in the condensation air duct 20 or accumulated substances such as flock and the like are reduced, so that the condensation air duct 20 can be ensured not to accumulate and be blocked by the flock, and the functional state of the condensation air duct 20 is normal, so that the normal operation of the drying function of the condensation type clothes drying device on clothes can be maintained, and in the operation process, the condensation type clothes drying device has a good drying effect; on the other hand, the lint is collected in the lint collector 40 for centralized storage, which is more convenient for cleaning than the lint accumulated in the condensation duct 20.
It should be noted that the condensation type clothes drying apparatus includes, in addition to the fan 30, other fans, for example, a fan which forms an air circulation between the drum 10 and the air duct (the condensation air duct 20 is a part of the air duct), and the fan blows hot air heated by the heating device provided in the air duct toward the drum and sucks low-temperature, high-humidity air in the drum, which carries moisture in clothes, into the condensation air duct. In particular, as far as the fan 30 is concerned, it may be a direct current fan, as shown in fig. 4.
As shown in fig. 1, 2, 5 and 6, the lint picker 40 is detachably coupled to the condensation-type clothes drying apparatus. The arrangement is convenient for disassembling the lint collector 40 from the condensing clothes drying device for cleaning when the lint stored in the lint collector 40 is required to be cleaned. More specifically, the lint picker 40 has a drawer structure, so that the lint picker 40 can be removed from the condensing type clothes drying apparatus in a drawing manner, and the operation thereof is simple and convenient.
The connecting pipe 50 can be specifically selected to be a rubber pipe, and the rubber pipe is low in cost and contributes to reducing the overall cost of the condensing clothes drying device. Meanwhile, the rubber tube can be made into a flexible tube, so that the rubber tube is convenient to store, install and the like.
A turbidity sensor is provided in the connecting pipe 50 for detecting the turbidity of the connecting pipe 50. The information on the turbidity of the connecting pipe 50 detected by the turbidity sensor is sent to the controller in the form of a signal. The controller receives a signal from the turbidity sensor containing turbidity information in the connecting duct 50 and controls the rotational speed of the fan 30 in dependence on this signal.
Specifically, when the turbidity of the connection pipe 50 is higher than a first set value, the controller controls the fan 30 to operate at a high rotation speed; when the turbidity of the connection duct 50 is lower than the first set value, the controller controls the fan 30 to operate at a low rotation speed. The first setting value is a reference value representing the turbidity of the connecting pipe 50, and the magnitude of the first setting value can be set according to needs or various factors. Generally, when the turbidity of the connecting pipe 50 is greater than the first set value, it is considered that the turbidity of the connecting pipe 50 is relatively large and the amount of the chad therein is relatively large (the amount of the chad in the connecting pipe 50 is positively correlated with the amount of the chad in the condensation air duct 20, and the change of the amount of the chad in the connecting pipe 50 slightly lags behind the change of the amount of the chad in the condensation air duct 20, but the slight lag can be ignored, so that the relatively large amount of the chad in the connecting pipe 50 reflects the amount of the chad in the condensation air duct 20 which needs to be transferred to the chad collector 40); when the turbidity of the connecting duct 50 is less than the first set value, it is considered that the turbidity of the connecting duct 50 is small and the shavings inside thereof are small. The fan 30 is operated at the high rotation speed and the low rotation speed does not mean that the fan 30 only has a high rotation speed gear and a low rotation speed gear, and the two rotation speed gears are adjusted; but means that the rotation speed of the fan 30 has an adjustable interval, and the rotation speed interval comprises a high rotation speed sub-interval with a high rotation speed and a low rotation speed sub-interval with a low rotation speed, and the specific ranges of the high rotation speed sub-interval and the low rotation speed sub-interval are set according to requirements or comprehensive factors. The operation of the fan 30 at the high speed indicates that the speed of the fan 30 is within the high speed sub-interval, and the speed of the fan 30 within the high speed sub-interval may also be variable (e.g., when the turbidity in the connecting duct 50 is significantly higher than the first set value, the speed of the fan 30 is a higher speed value of the high speed sub-interval, and when the turbidity in the connecting duct 50 is less than the first set value, the speed of the fan 30 is a lower speed value of the high speed sub-interval). Similarly, the fan 30 operating at a low speed indicates that the fan 30 is operating at a speed within the low speed sub-interval, and the speed of the fan 30 within the low speed sub-interval may also be variable (e.g., when the turbidity in the connecting duct 50 is slightly lower than the first set value, the speed of the fan 30 is a higher speed value of the low speed sub-interval, and when the turbidity in the connecting duct 50 is significantly lower than the first set value, the speed of the fan 30 is a lower speed value of the low speed sub-interval).
The turbidity sensor can specifically detect the turbidity of the connecting pipeline 50 by using a photoelectric coupling principle, and is internally provided with a light emitting diode and a triode, wherein the light emitting diode is used as a transmitting tube, and the triode is used as a receiving tube. When the amount of the flock in the connecting pipeline 50 is large, the turbidity of the connecting pipeline 50 is high, in this case, the refraction program of the light-emitting diode is high, the illumination received by the triode is small, and the triode approaches to an unsaturated state, otherwise, when the amount of the flock in the connecting pipeline 50 is small, the turbidity of the connecting pipeline 50 is low, in this case, the refraction program of the light-emitting diode is low, the illumination received by the triode is large, and the triode approaches to a saturated state; in summary, the amount of the flocks in the connecting pipe 50 affects the turbidity of the connecting pipe 50, and the turbidity of the connecting pipe 50 affects the output voltage of the turbidity sensor, so that the turbidity of the connecting pipe 50 can be determined according to the output voltage of the turbidity sensor, and the amount of the flocks in the connecting pipe 50 can be determined.
For example, when the turbidity sensor is powered on by 5V, if the output voltage is 0-2V, it may indicate that the turbidity of the connecting pipe 50 is high, which indicates that the amount of chad in the connecting pipe 50 is large; and if the output voltage of the turbidity sensor is 2-5V, the turbidity of the connecting pipeline 50 can be indicated to be lower, the connecting pipeline 50 is indicated to be cleaner, and the quantity of the internal flocks is less.
If the first set value is set as the turbidity of the connecting pipeline 50 when the output voltage of the turbidity sensor is 2V, in the above example, when the output voltage of the turbidity sensor is 0-2V, the amount of the flock in the connecting pipeline 50 is large, and the turbidity of the connecting pipeline is higher than the first set value, at this time, after the controller receives the signal from the turbidity sensor, the controller controls the fan 30 to operate at a high rotation speed, so that the flock is more quickly conveyed and stored in the flock collector 40; when the output voltage of the turbidity sensor is 2-5V, the quantity of the flock in the connecting pipeline 50 is small, the turbidity of the connecting pipeline 50 is lower than a first set value, at the moment, the controller controls the fan 30 to operate at a low rotating speed after receiving a signal from the turbidity sensor, and at the moment, the noise and vibration generated by the operation of the fan 30 are low, so that the interference to the user environment is small.
The connection part of the fan 30 and the connecting pipeline 50 is provided with the grating 31, and the grating 31 is used for blocking the flock in the connecting pipeline 50, so that the flock is prevented from being accumulated at the fan 30 in a large amount in the moving process in the connecting pipeline 50, and the normal blowing or exhausting of the fan 30 is prevented from being interfered. As shown in fig. 3, the fan 30 is installed above the lint collector 40, and a wind guide opening 41 is formed on one side of the lint collector 40 facing the fan 30, as shown in fig. 6, the wind guide opening 41 is used for the fan 30 to form a flowing air flow in the connecting duct 50; the grill 31 is disposed between the air guide opening 41 of the lint collector 40 and the fan 30.
A pressure sensor is arranged on the grid 31; an indicator lamp for indicating the information of the amount of lint inside the lint collector 40 is provided on the lint collector 40. The controller of the condensing clothes drying device controls the indicating state of the indicating lamp according to the pressure information detected by the pressure sensor. After condensing clothes drying device dries the clothing for a long time, the flock in the flock collector 40 constantly accumulates, when the flock accumulation to a certain extent, the flock of accumulation in the flock collector 40 can contact with pressure sensor, and form certain pressure to pressure sensor, pressure sensor can the perception this pressure, according to this pressure information, can judge how much of the flock of accumulation in the flock collector 40, thereby when the flock quantity of accumulation is more in the flock collector 40, the instruction state of pilot lamp just can be controlled to the controller, the information that needs the clearance to user transmission flock collector 40.
Specifically, the pressure value at which the lint acts on the pressure sensor may be determined based on the voltage of the output signal of the pressure sensor. For example, if the output voltage of the pressure sensor is 2.5-5V, the pressure value of the lint in the lint collector 40 acting on the pressure sensor is determined to be large, and information for cleaning the lint collector 40 should be transmitted to the user. On the contrary, if the output voltage of the pressure sensor is 0-2.5V, the pressure value of the flock acting on the pressure sensor in the flock collector 40 can be determined to be small, the information of cleaning the flock collector 40 does not need to be transmitted to a user, and the flock collector 40 can normally work. Of course, for example, the interval between 2.5-5V and 0-2.5V can be adjusted, such as 3-5V and 0-3V.
A proximity switch is provided at a side of the drawer structure of the lint collector 40 facing the inside of the condensation-type clothes drying apparatus (i.e., the left side in fig. 6) in a direction in which the drawer structure of the lint collector 40 is drawn. In one aspect, the proximity switch is provided to determine whether the lint picker 40 is installed in place during the process of reinstalling the lint picker 40 after cleaning is completed while the lint picker 40 is being cleaned. Specifically, if the proximity switch is on, it indicates that the lint picker 40 is mounted in place, and if the proximity switch is not on, it indicates that the lint picker 40 is not mounted in place. On the other hand, when the lint collector 40 is cleaned, in the process of drawing the lint collector 40 outwards, the fan 30 can be kept running continuously before the proximity switch is not connected, and the transportation and transfer of the lint in the condensation air duct 20 and the connecting pipeline 50 are prolonged.
Specifically, the condensing type clothes drying apparatus in the present embodiment may be a washing and drying machine having washing and drying functions or a dryer having only drying functions.
In summary, in the condensing clothes drying apparatus provided in the embodiment of the present invention, in the overall structure for cleaning the lint in the condensing air duct 20, which is composed of the fan 30, the lint collector 40 and the connecting duct 50, a turbidity sensor is disposed in the connecting duct 50, the turbidity of the connecting duct 50 is detected by the turbidity sensor, and the rotation speed of the fan 30 is controlled by the controller according to the detected turbidity information of the connecting duct 50; the arrangement can enable the rotating speed of the fan 30 to be adaptive to the turbidity of the connecting pipeline 50, and the turbidity of the connecting pipeline 50 is influenced and determined by the quantity of the flocks in the connecting pipeline 50 (the quantity of the flocks in the connecting pipeline 50 is positively correlated with the quantity of the flocks in the condensation air channel 20), so that the rotating speed of the fan 30 can be adaptive to the quantity of the flocks in the connecting pipeline 50, and therefore, when the quantity of the flocks in the connecting pipeline 50 is large, the rotating speed of the fan 30 can be increased and the fan runs at a high rotating speed, so that the flocks in the condensation air channel 20 and the connecting pipeline 50 can be transferred and conveyed into the flocks collector 40 more quickly; when the amount of the flocks in the connecting pipe 50 is small, the rotating speed of the fan 30 can be correspondingly reduced, and the fan operates at a low rotating speed, so that the noise and vibration caused by the operation of the fan 30 can be reduced.
(2) Embodiment of method for drying laundry
In this embodiment, the method for drying the clothes is basically based on the condensing type clothes drying apparatus described in the above embodiment of the condensing type clothes drying apparatus to dry the clothes (including the following description of the method for drying the clothes provided by this embodiment is also based on the condensing type clothes drying apparatus), and of course, other devices outside the condensing type clothes drying apparatus have a physical basis for implementing the method for drying the clothes provided by this embodiment, and the method for drying the clothes provided by this embodiment can also be implemented on the other devices.
As shown in fig. 7, the method for drying laundry provided by the present embodiment includes the following steps S10 to S12.
Step S10, the turbidity in the connecting pipe 50 is detected.
In step S10, the turbidity of the connecting duct 50 may be detected by a turbidity sensor provided in the connecting duct 50.
Specifically, the turbidity sensor may specifically detect the turbidity of the connection pipe 50 by using a principle of photoelectric coupling, and a light emitting diode and a triode are disposed inside the turbidity sensor, wherein the light emitting diode is used as a transmitting tube, and the triode is used as a receiving tube. When the amount of the flock in the connecting pipeline 50 is large, the turbidity of the connecting pipeline 50 is high, in this case, the refraction program of the light-emitting diode is high, the illumination received by the triode is small, and the triode approaches to an unsaturated state, otherwise, when the amount of the flock in the connecting pipeline 50 is small, the turbidity of the connecting pipeline 50 is low, in this case, the refraction program of the light-emitting diode is low, the illumination received by the triode is large, and the triode approaches to a saturated state; in summary, the amount of the flocks in the connecting pipe 50 affects the turbidity of the connecting pipe 50, and the turbidity of the connecting pipe 50 affects the output voltage of the turbidity sensor, so that the turbidity of the connecting pipe 50 can be determined according to the output voltage of the turbidity sensor, and the amount of the flocks in the connecting pipe 50 can be determined. The amount of the flocks in the connecting pipe 50 is positively correlated with the amount of the flocks in the condensing air duct 20, and the amount of the flocks in the connecting pipe 50 slightly lags behind the amount of the flocks in the condensing air duct 20, but the slight lag can be ignored, so that the amount of the flocks in the connecting pipe 50 reflects the amount of the flocks in the condensing air duct 20, which need to be conveyed and transferred to the flocks collector 40.
Step S11, the turbidity of the connecting pipe 50 is compared with the first set value.
In step S11, the first setting value is a reference value representing the turbidity of the connecting pipe 50, and can be set according to various requirements or factors. Generally, when the turbidity of the connecting pipe 50 is greater than the first set value, it is considered that the turbidity of the connecting pipe 50 is greater and the amount of the chad inside the connecting pipe is greater (i.e. the amount of the chad in the condensing air duct 20 that needs to be transported and transferred to the chad collector 40 is greater); when the turbidity of the connecting pipe 50 is less than the first setting value, the turbidity of the connecting pipe 50 is considered to be smaller, and the fluff inside the connecting pipe 50 is considered to be less (i.e. the amount of the fluff in the condensation duct 20 to be transported and transferred to the fluff collector 40 is less).
For example, when the turbidity sensor is powered on by 5V, if the output voltage is 0-2V, it may indicate that the turbidity of the connecting pipe 50 is high, which indicates that the amount of chad in the connecting pipe 50 is large; and if the output voltage of the turbidity sensor is 2-5V, the turbidity of the connecting pipeline 50 can be indicated to be lower, the connecting pipeline 50 is indicated to be cleaner, and the quantity of the internal flocks is less. In this example, the turbidity of the connecting pipe 50 at an output voltage of 2V of the turbidity sensor is set to the first set value.
Step S12, controlling the rotating speed of the fan 30 according to the comparison result of the turbidity of the connecting pipeline 50 and the first set value; when the turbidity of the connecting pipeline 50 is higher than the first set value, controlling the fan 30 to operate at a high rotating speed; when the turbidity of the connection pipe 50 is lower than the first set value, the fan 30 is controlled to operate at a low rotation speed.
In step S12, the fan 30 is operated at the high rotation speed and the low rotation speed, which does not mean that the fan 30 only has the high rotation speed gear and the low rotation speed gear, and the adjustment is performed on the two rotation speed gears; but rather, the rotational speed of the fan 30 has an adjustable interval, which includes a high rotational speed sub-interval with a higher rotational speed and a low rotational speed sub-interval with a lower rotational speed, and the specific ranges of the high rotational speed sub-interval and the low rotational speed sub-interval are set according to requirements or comprehensive factors. The operation of the fan 30 at the high speed indicates that the speed of the fan 30 is within the high speed sub-interval, and the speed of the fan 30 within the high speed sub-interval may also be variable (e.g., when the turbidity in the connecting duct 50 is significantly higher than the first set value, the speed of the fan 30 is a higher speed value of the high speed sub-interval, and when the turbidity in the connecting duct 50 is less than the first set value, the speed of the fan 30 is a lower speed value of the high speed sub-interval). Similarly, the fan 30 operating at a low speed indicates that the fan 30 is operating at a speed within the low speed sub-interval, and the speed of the fan 30 within the low speed sub-interval may also be variable (e.g., when the turbidity in the connecting duct 50 is slightly lower than the first set value, the speed of the fan 30 is a higher speed value of the low speed sub-interval, and when the turbidity in the connecting duct 50 is significantly lower than the first set value, the speed of the fan 30 is a lower speed value of the low speed sub-interval).
As an example in the step S11, if the first setting value is set to be the turbidity of the connecting pipe 50 when the output voltage of the turbidity sensor is 2V, in the above example, when the output voltage of the turbidity sensor is 0-2V, the amount of the flock in the connecting pipe 50 is large, and the turbidity of the connecting pipe is higher than the first setting value, at this time, the controller receives the signal from the turbidity sensor and then controls the fan 30 to operate at a high rotation speed, so as to more quickly convey and store the flock into the flock collector 40; when the output voltage of the turbidity sensor is 2-5V, the amount of the flock in the connecting pipeline 50 is small, the turbidity of the connecting pipeline 50 is lower than a first set value, at the moment, the controller controls the fan 30 to operate at a low rotating speed after receiving a signal from the turbidity sensor, at the moment, the noise and vibration generated by the operation of the fan 30 are low, and the interference to the user environment is small.
In addition to the above steps S10 to S12, as shown in fig. 8, the method for drying laundry according to the present embodiment further includes the following steps S20 to S23.
Step S20, comparing the turbidity of the connecting pipe 50 with a second set value; the second set value is lower than the first set value.
In step S20, the second setting value is determined in accordance with the first setting value, and may be set according to need or by combining various factors. In determining the second set point, the only limitation is that the second set point is lower than the first set point.
In the case where the second set value is lower than the first set value, as a result of comparing the turbidity of the connecting duct 50 with the second set value, if the turbidity of the connecting duct 50 is lower than the second set value, it indicates that the inside of the connecting duct 50 is relatively clean and the amount of chad therein is relatively small.
Step S21, detecting a duration of time during which the turbidity of the connecting duct 50 is lower than the second set value.
In step S21, the cumulative time during which the turbidity of the connecting duct 50 continues to be below the second set value is obtained from the time at which the turbidity of the connecting duct 50 starts to fall below the second set value each time as a starting point.
Step S22, detecting the operating state of the fan 30 when the duration of the turbidity of the connecting pipe 50 being lower than the second set value is longer than the set time.
In step S22, the value of the set time may be determined according to the need or by combining various factors. The detecting of the working state of the fan 30 mainly means whether the fan 30 is working normally.
Step S23, if the fan 30 can not work normally, an alarm signal is sent out; if the fan 30 can work normally, the fan 30 is controlled to operate at a low rotation speed.
In step S23, the failure of the fan 30 to operate normally indicates that it cannot generate an effective airflow from the condensation duct 20 to the lint collector 40 in the connecting duct 50, and cannot suck the lint in the condensation duct 20 from the condensation duct 20 to the connecting duct 50. In this case, the inside of the connecting pipe 50 obtained according to the fact that the turbidity degree of the connecting pipe 50 is lower than the second set value is relatively clean, and the conclusion that the amount of the shavings in the connecting pipe 50 is relatively small is false, because the fan 30 cannot suck the shavings from the condensation air duct 20 into the connecting pipe 50, the cleaning of the shavings in the condensation air duct 20 cannot be realized in this case, and therefore, in this case, an alarm signal needs to be sent to prompt a user to repair the fan 30. If the fan 30 can work normally, it means that the connecting pipe 50 is cleaner and the amount of the flock in the connecting pipe 50 is less, which is obtained according to the turbidity of the connecting pipe 50 being lower than the second set value, is "true" because the airflow formed by the fan 30 in the connecting pipe 50 conveys the flock in the condensing air duct 20 and the connecting pipe 50 into the flock collector 40.
In addition to the above steps S10 to S12 and steps S20 to S23, as shown in fig. 9, the method for drying laundry according to the present embodiment further includes the following steps S30 to S32.
Step S30 detects the pressure applied to the pressure sensor on the grill 31.
In step S30, the pressure value at which the lint acts on the pressure sensor may be determined based on the voltage of the output signal of the pressure sensor. For example, if the output voltage of the pressure sensor is 2.5-5V, the pressure value of the flock in the flock collector 40 acting on the pressure sensor is considered to be larger under the condition that the pressure sensor is also powered by 5V. On the contrary, if the output voltage of the pressure sensor is 0 to 2.5V, it can be determined that the pressure value of the flock in the flock collector 40 acting on the pressure sensor is small. Of course, for example, the interval between 2.5-5V and 0-2.5V can be adjusted, such as 3-5V and 0-3V.
Step S31, the detected pressure value is compared with a set value.
In step S31, the specific value of the set value can be determined according to the need or the combination of various factors. In the above step, the pressure values to which the pressure sensor is subjected when the output voltage of the pressure sensor is 2.5V and 3V are set as set values, respectively.
Step S32, determining whether to send out a signal for cleaning the flock collector 40 according to the comparison result of the detected pressure value and the set value; when the detected pressure value is larger than the set value, a signal for cleaning the lint collector 40 is sent out, and when the detected pressure value is smaller than the set value, the signal for cleaning the lint collector 40 is not sent out.
In step S32, after the laundry is dried for a long time, the lint in the lint collector 40 is accumulated, and when the lint is accumulated to a certain extent, the lint accumulated in the lint collector 40 contacts the pressure sensor and exerts a certain pressure on the pressure sensor, and the pressure sensor can sense the pressure, and according to the pressure information, the amount of the lint accumulated in the lint collector 40 can be determined, so that the pressure value detected by the pressure sensor reflects the amount of the lint in the lint collector 40. It can be understood that after the amount of the lint collected in the lint collector 40 exceeds a certain value, the lint collector 40 needs to be cleaned to dump the accumulated lint in the lint collector 40, and then the lint from the condensing duct 20 can be continuously received and stored.
In summary, in the method for drying laundry provided in this embodiment, by detecting the turbidity of the connecting pipe 50, when the turbidity in the connecting pipe 50 is higher than the first set value, the fan 30 is controlled to operate at a high rotation speed, and when the turbidity in the connecting pipe 50 is lower than the first set value, the fan 30 is controlled to operate at a low rotation speed. Therefore, the rotating speed of the fan 30 can be adapted to the turbidity of the connecting pipeline 50, and the turbidity of the connecting pipeline 50 is influenced and determined by the amount of the flocks in the connecting pipeline 50 (the amount of the flocks in the connecting pipeline 50 is positively correlated with the amount of the flocks in the condensation air duct 20), so that the rotating speed of the fan 30 can be adapted to the amount of the flocks in the connecting pipeline 50, and therefore, when the amount of the flocks in the connecting pipeline 50 is large, the rotating speed of the fan 30 can be increased and the fan runs at a high rotating speed, so that the flocks in the condensation air duct 20 and the connecting pipeline 50 can be transferred to the flocks collector 40 more quickly; when the amount of the flocks in the connecting pipe 50 is small, the rotating speed of the fan 30 can be correspondingly reduced, and the fan operates at a low rotating speed, so that the noise and vibration caused by the operation of the fan 30 can be reduced.
