Problems solved by technology

The above scheme improves the drying effect and reduces energy loss, but the load of the motor cannot be directly detected, and is generally obtained indirectly by detecting the current of the motor, but the current will be affected by the magnitude and fluctuation of the voltage and the drying speed, so Detection accuracy is not high

Embodiment 1

[0030] This embodiment provides a drying control method for a clothes drying device. The clothes drying device includes a motor that drives the clothes to rotate, a speed detector that detects the speed of the motor, and a controller that controls the operation of the motor. The controller has a timer device and counter, and the speed measuring device is connected with the controller. The drying device of the present invention uses the motor to drive the drying barrel to rotate, and the clothes are continuously turned over in the drying barrel to completely evaporate the moisture in the clothes, and finally complete the drying. The drying process of the drying device is divided into three stages, The starting stage R, the drying stage S and the drying completion stage T, the present invention mainly detects and judges the drying stage S and the drying completion stage T.

Embodiment 2

[0045] This embodiment provides a clothes drying device, which uses the drying control method of the clothes drying device in any of the above embodiments to control the drying of clothes, especially a washing machine with a dryer, which includes a casing, an outer A barrel, an inner barrel, and a controller located above the outer barrel and connected to the housing, the inner barrel is connected to the motor as a drying barrel, and the washing machine performs washing, dehydration, and drying of clothes in sequence, using the existing controller and rotating speed The tester can also realize the dehydration control of the washing machine. Also according to the influence of the weight reduction of the clothes on the motor speed during the dehydration process, the two stages of dehydration and drying are controlled by detecting the speed, reducing the number of parts of the whole washing machine. Interference during component installation and operation is reduced.

Abstract

The invention discloses a drying controlling method of a clothes drying device. The problem of low accuracy of drying detection of clothes is solved. The method comprises the steps that 1, the clothes drying device is started, drying duration is calculated, and step 2 is entered; 2, when drying duration reaches a preset time value, step 3 is entered; 3, the current rotational speed of a motor is detected, and step 4 is entered; 4, when drying duration reaches the preset time value, step 5 is entered; 5, the current rotational speed of the motor is detected, and step 6 is entered; 6, if the current rotational speed is larger than the rotational speed from previous detection, step 4 is returned, otherwise, the count value is added by 1, and step 7 is entered; 7, if the count value reaches a preset accumulated value, the motor brakes, and otherwise, step 4 is returned. The invention further provides the clothes drying device adopting the above drying controlling method. By means of the drying controlling method and the clothes drying device, not only can drying conditions of the clothes be monitored in real time so that energy waste caused by over-drying can be avoided, but the detection principle and the detection structure are simple.

Description

technical field [0001] The invention relates to a drying control method of a clothes drying device, in particular to a drying stop control method of the clothes drying device, and also relates to a clothes drying device. Background technique [0002] In the design scheme of the existing clothes drying device, two methods are mainly used. One is to use the operation program of drying time solidification, because clothes with different loads, different materials, and different initial moisture content have different drying efficiencies. , the optimal drying time will be different, causing the clothes to be incompletely dried or the drying time is too long; the other is to detect changes in the temperature of the clothes, that is, to set thermistors at the drying air inlet and air outlet respectively, Separately detect the temperature of the drying air inlet and air outlet, and judge whether the clothes are dry by the temperature difference. However, this detection method needs...
