Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following detailed description of the technical solutions of the present invention is provided with reference to the accompanying drawings and examples. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, an embodiment of the present invention provides a washing machine control method, including the following steps:
s11: heating clothes to be dried in the washing machine;
s12: determining the temperature difference caused by temperature rise in the washing machine;
s13: and judging whether to dehydrate the dried clothes according to the temperature difference.
According to the control method of the washing machine provided by the embodiment of the invention, firstly, clothes to be dried in the washing machine are heated, and then the temperature difference caused by heating in the washing machine is determined; and judging whether to dehydrate the clothes to be dried according to the temperature difference. When the water content in the clothes to be dried is different, the temperature difference caused by temperature rise is different, so that the water content in the clothes to be dried can be determined according to different temperature differences; if the water content is low, dehydration is not carried out, and direct drying is carried out; and (5) dehydrating and then drying the mixture after the water content is high. The control method provided by the embodiment of the invention adopts the scheme that clothes to be dried are heated in advance, and the moisture content is judged according to the temperature difference; can be when waiting to dry clothes moisture content low, do not dewater the stoving clothing, direct drying practices thrift the energy consumption, can not bring the adherence risk.
In one embodiment, the present invention further provides a flowchart of a specific washing machine control method, as shown in fig. 2:
s21: and acquiring the weight of the clothes to be dried before temperature rise.
S22: and determining the target time length of temperature rise according to the weight. It can be understood that the greater the weight of the laundry to be dried, the longer the target time period for warming up.
S23: the temperature of the laundry to be dried in the washing machine is raised for a target time period. It should be noted that, the heating process is performed by the heating device or the drying device of the washing machine, so the gear or power of the heating device or the drying device is not changed during the heating process.
S24: and acquiring a first temperature difference between the air inlet temperature and the air outlet temperature of the washing machine after the temperature rise is finished. It can be understood that the clothes to be dried with higher water content are lower in air outlet temperature after the temperature rise is finished, and therefore the water content of the clothes to be dried can be judged according to the difference value of the air inlet temperature and the air outlet temperature.
S25: and if the first temperature difference is not less than the first preset difference, dehydrating and drying. And when the first temperature difference is not less than the first preset difference, the moisture content is high, and drying is carried out after dehydration.
S26: and if the first temperature difference is smaller than the first preset difference, the drying is directly carried out without dehydration. When the first temperature difference is smaller than the first preset difference value, the moisture content is low, dehydration is not needed, and drying is directly carried out. In the practical application process, the first preset difference corresponds to a theoretical difference with the water content of 50%. Even if the moisture content of the clothes to be dried is 50% in different weights, the first temperature difference is different after the temperature rise is finished, so that the first preset difference value is related to the weight of the clothes to be dried before the temperature rise. What the first preset difference value is at each weight may be determined experimentally in advance.
According to the specific washing machine control method provided by the embodiment of the invention, the types of clothes to be dried are obtained firstly during drying, and the pre-heating target time duration is determined according to the weight. And waiting for the end of the pre-heating operation, judging a first temperature difference between the air outlet temperature and the air inlet temperature, and judging whether to start a dehydration program according to the temperature difference. When the first temperature difference is larger than or equal to the first preset difference value, the dehydration program is started, and at the moment, the dehydration program can quickly reduce the moisture content of the clothes in the washing drum. And when the first temperature difference is smaller than the first preset difference value, the dehydration procedure is not carried out, and the conventional drying process is directly carried out. Can effectively save energy consumption and reduce the wall-adhering risk.
It should be noted that, in the above embodiment, when the target temperature-increasing time length is determined, a fixed preset time length may be directly adopted, the weight of the laundry to be dried does not need to be acquired, and then the target time length is determined according to the weight.
As a supplementary explanation to the above embodiment, the water content may be determined not by using the first temperature difference between the inlet air temperature and the outlet air temperature of the washing machine, but by using the second temperature difference between the outlet air temperature of the washing machine after the temperature rise and the outlet air temperature before the temperature rise. Specifically, if the second temperature difference is not less than a second preset difference, dehydration is not performed; and if the second temperature difference is smaller than the second preset difference, dehydrating.
By the method, the moisture content of the clothes to be dried can be judged when the drying program is started. When the moisture content of the load is low, the dehydration operation is not carried out, the drying process is continuously carried out, the energy consumption is saved, the time is shortened, the noise influence is reduced, and the risk of sticking the bucket to the load is reduced. User experience is optimized, and drying effect is improved.
In one embodiment, the present invention further provides a control apparatus of a washing machine, as shown in fig. 3, including:
a clothes warming module 31 for warming clothes to be dried in the washing machine; alternatively, the laundry warming module 31 warms up the laundry to be dried in the washing machine for a preset fixed time period. Or, the laundry warming module 31 obtains the weight of the laundry to be dried before warming; determining the target time length of temperature rise according to the weight; the temperature of the laundry to be dried in the washing machine is raised for a target time period.

And a dehydration judging module 33 for judging whether to dehydrate the dried clothes according to the temperature difference. Optionally, if the first temperature difference is smaller than the first preset difference, the dehydration determining module 33 does not perform dehydration; if the first temperature difference is not less than the first preset difference, the dehydration determining module 33 performs dehydration. Or, if the second temperature difference is not less than the second preset difference, the dehydration determining module 33 does not perform dehydration; if the second temperature difference is smaller than the second preset difference, the dehydration determining module 33 performs dehydration.
