Technical Field

The invention belongs to the field of washing machines, and particularly relates to a dewatering and heating control method for a washing machine and the washing machine.

Background

The existing washing machine part has a heating function, namely the washing machine part has the heating function in the washing stage, a user can set the heating temperature, the purpose is to improve the activity of a detergent and enable clothes to be washed more cleanly, however, when the user washes clothes in winter, the washing machine stops heating after the washing stage due to the fact that the temperature of tap water injected into the washing machine is low, then the washing machine is rinsed by injecting water into the washing machine in the rinsing stage, the temperature in the washing machine is low, after the last dehydration is finished, the condition that the clothes are cold can occur when the user takes the clothes for airing, and the user experience is poor.

The present invention has been made in view of this situation.

Disclosure of Invention

The technical problem to be solved by the invention is to overcome the defects of the prior art and provide a washing machine dehydration heating control method and a washing machine, so that the washing machine can heat clothes in a dehydration stage, the clothes have a certain temperature after the dehydration stage is finished, and when a user takes out the clothes after washing and dries the clothes in the air under the condition of cold weather, the user experience is not poor due to cold clothes.

In order to solve the technical problems, the invention adopts the technical scheme that:

a washing machine dehydration heating control method is characterized in that the washing machine obtains the temperature of last rinsing water, and when the temperature value of the last rinsing water is lower than a first set value, clothes in a drum of the washing machine are heated.

Furthermore, the temperature value of the last rinsing water is the temperature value of the water inflow into the barrel in the last rinsing water inflow process, or the temperature value of the water before the last rinsing water drainage process is finished, or the temperature value of the water in the washing machine barrel after the last rinsing water drainage process is finished.

Further, the heating of the laundry inside the drum of the washing machine should be carried out before the end of the dehydration process;

preferably, the laundry in the drum of the washing machine is heated to the second set value before the dehydration process is finished.

Further, the heating mode for heating the clothes is to directly heat air in a cylinder in which the clothes are positioned, so that the temperature of the clothes is increased; and/or introducing high-temperature airflow into the cylinder where the clothes are positioned to heat the clothes.

Further, when the temperature in the cylinder in which the clothes are positioned is detected to be heated to a second set value, the heating is stopped;

preferably, when the time for detecting that the temperature in the drum where the clothes are located is higher than the second set value is longer than the set time period, the heating is stopped.

And further, judging whether the washing program selected by the user is a preset program which needs to execute special dehydration heating, and if so, heating the clothes in the drum of the washing machine in the dehydration process no matter whether the detected temperature of the last rinsing water is lower than a first set value.

Further, after the user triggers the forced dehydration heating instruction to the washing machine, no matter what washing program is executed by the washed clothes, and no matter whether the detected water temperature of the last rinsing water is lower than the first set value, the clothes in the barrel of the washing machine are heated in the dehydration process.

Further, the first set value and the second set value are different preset values, and the first set value is smaller than the second set value;

preferably, the first setting value and the second setting value are set by a user.

The present invention also provides a washing machine having any one of the above-mentioned dehydration heating control methods, including:

the temperature detection unit is used for detecting the water temperature of the last rinsing water and/or the temperature in the washing machine barrel;

and the heating unit is used for heating the clothes in the drum of the washing machine in the dehydration process.

Furthermore, a trigger module for a user to select a washing program is arranged on the washing machine;

preferably, the washing machine is provided with a receiving module for receiving a command of triggering forced dehydration and heating issued by a user.

After the technical scheme is adopted, compared with the prior art, the invention has the following beneficial effects.

The invention provides a dewatering and heating control method of a washing machine and the washing machine, wherein a user puts clothes into the washing machine, starts the washing machine, selects a washing program, judges whether the washing program selected by the user is a preset program which needs to execute special dewatering and heating, if the washing program does not need to execute the special dewatering and heating, the washing machine works according to the washing program selected by the user, a temperature detection unit in the washing machine detects the water temperature value of last rinsing water in the water inlet process of last rinsing, the last rinsing process or before the last rinsing drainage is finished, and judges the size relation between the water temperature value of last rinsing water and a first set value, if the water temperature value of last rinsing water is more than or equal to the first set value, the clothes are not heated, and if the water temperature value of last rinsing water is less than the first set value, a heating unit in the washing machine heats the clothes in a machine barrel, heating the clothes to a second set value, and stopping heating; if the washing machine judges that the washing program selected by the user is a program needing to execute special dehydration heating, the washing machine executes the washing program, and meanwhile, no matter what the temperature of the last rinsing water detected by a temperature detection unit in the washing machine is, whether the temperature of the last rinsing water is greater than a first set value or not, a heating unit in the washing machine heats the clothes in a washing machine barrel, heats the clothes to a second set value, and stops heating; if the user triggers a forced dehydration heating instruction when the clothes need to be washed, a receiving module for receiving the forced dehydration heating instruction sent by the user is arranged on the washing machine, after the module receives the forced dehydration heating instruction sent by the user, no matter what the washing program selected by the user is, no matter whether the detected temperature of the last rinsing water is lower than a first set value, as long as the user triggers the forced dehydration heating instruction, the heating unit heats the clothes in the washing machine cylinder when the washing process of the washing machine is carried out in the dehydration process, heats the clothes to a second set value, stops heating, enables the clothes to have proper temperature after the washing is finished, and is convenient for the user to take the clothes for airing.
