Detailed Description
In order to make the technical problems solved, the technical solutions adopted and the technical effects achieved by the present invention clearer, the technical solutions of the present invention are further described below by way of specific embodiments with reference to the accompanying drawings.
The embodiment provides a control method of a clothes drying device, which can be suitable for a large-capacity clothes drying device and is beneficial to improving the drying efficiency of clothes, thereby improving the use experience of customers.
As shown in figure 1, when the clothes are dried, the fan of the clothes drying equipment is started, the drying degree of the clothes is monitored in real time, and the rotating speed of the fan is controlled according to the drying degree of the clothes, so that the rotating speed of the fan is adjusted according to the actual condition of the clothes, the drying efficiency of the clothes is improved, and the user experience is improved on the basis that the energy consumption of the fan is reduced as far as possible.
Specifically, as shown in fig. 2, after the fan is started, the rotation speed of the fan is gradually increased and stabilized at a first rotation speed preset in the program, and the fan operates at the first rotation speed. After the rotational speed of fan reached first rotational speed, the inside heater of clothing drying equipment started, and the cooperation fan produces hot-air, and hot-air and wet clothing contact for moisture in the wet clothing evaporates into vapor, and the wet hot-air that thoughtlessly has vapor is outside the clothing drying barrel by the stoving wind channel discharge, thereby realizes the purpose of stoving clothing.
As the laundry drying apparatus is operated, the laundry tub is rotated, the moisture in the laundry is gradually reduced due to friction between the laundry, but the laundry friction generates a large amount of lint. The thread scraps enter the drying air duct along with the damp and hot air. In order to avoid the blockage of the drying air channel by the thread scraps, a filter screen is arranged in the drying air channel and is accumulated on the filter screen to influence the flow of hot air, so that the drying efficiency of clothes is influenced, the drying time of the clothes and the cooling time of the clothes drying barrel are prolonged, and especially, the use experience of a user is influenced under the condition that the clothes are more.
For this reason, the rotation speed of the fan is controlled according to the drying degree of the laundry in the present embodiment. When the drying degree of the detected clothes reaches the preset value, the fact that certain thread scraps are accumulated on the filter screen in the drying air channel is shown, the rotating speed of the fan is controlled to be increased, and therefore the fact that the thread scraps influence the drying efficiency of the clothes is avoided.
When lint accumulates on the filter screen, the flow of hot air is blocked, resulting in a reduction in the power of the fan. The larger the clothes drying degree is, the more the accumulated thread scraps are, the more serious the air blockage is, and correspondingly, the more obvious the fan power change is.
For this reason, in the embodiment, the drying degree of the laundry may be judged by the variation value of the fan power. When the drying degree of the clothes reaches a preset value, the change value of the power of the fan reaches a corresponding preset change value. And when the power change value of the fan reaches a preset change value, controlling the rotating speed of the fan to increase to a second rotating speed. The second rotating speed is greater than the first rotating speed, so that the drying efficiency of the clothes is guaranteed under the condition that the air duct is blocked.
In other embodiments, the drying degree of the clothes can be judged according to the starting time of the fan. Specifically, as the starting time of the blower is extended, the drying degree of the laundry is increased, and the more thread scraps are generated, so that when the drying degree of the laundry reaches a preset value, the starting time of the blower reaches a corresponding preset time.
Because the drying degrees of the clothes with different weights in the same drying time are different, when the clothes are more, the drying degree is lower, and when the clothes are less, the drying degree is lower, therefore, different preset times are correspondingly set in the program aiming at the clothes with different weights. After the clothes are put in, the weight range of the clothes is judged by weighing the weight of the clothes, so that the preset time for starting the fan in the weight range is obtained.
When the rotating speed of the fan is increased to the second rotating speed, whether the clothes in the clothes drying barrel reach the drying condition or not can be detected, and if the clothes in the clothes drying barrel reach the drying condition, the heater is turned off and heating is stopped. Specifically, whether the drying condition is satisfied can be judged by detecting the humidity of the air in the air outlet of the clothes drying barrel. The humidity of the air in the clothes drying barrel is gradually reduced along with the gradual drying of the clothes, and when the humidity of the air in the air outlet of the clothes drying barrel reaches the preset humidity, the clothes meet the drying condition. Optionally, the preset humidity may be 20% -30%, such as 20%, 22%, 24%, 26%, 28%, 30%.
Because the hot air is continuously introduced into the clothes drying barrel for a period of time, the temperature of the clothes drying barrel and the temperature of the clothes are higher, and in order to avoid the damage of the clothes drying barrel or the scald of the user by the clothes, the fan continuously works for a period of time so as to cool the clothes drying barrel and the clothes.
And after the heater is turned off, detecting the temperature in the clothes drying barrel, and when the temperature in the clothes drying barrel is lower than the preset temperature, turning off the fan to finish cooling the clothes and the clothes drying barrel.
After the clothes are dried and cooled, the clothes drying equipment sends prompt information to remind a user of cleaning a filter screen in the air duct so as to dry the clothes next time.
The present embodiment also provides a laundry drying apparatus, which may be, for example, a clothes dryer or a washing machine having a drying function. The clothes drying equipment comprises a box body, a controller and a clothes drying barrel which is rotatably arranged in the box body, a drying air channel is formed between the clothes drying barrel and the box body, and a fan and a heater are arranged in the drying air channel, wherein the fan is a variable frequency fan so as to adjust the rotating speed of the fan. The controller is respectively electrically connected with the fan and the heater, is used for controlling the fan and the heater to work, and operates according to the control method of the clothes drying equipment.
The above description is only a preferred embodiment of the present invention, and for those skilled in the art, the present invention should not be limited by the description of the present invention, which should be interpreted as a limitation.
