detailed description

The technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, and it is obvious that the described embodiments are only the present invention. Some embodiments, but not all of the embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

1 is a flow chart of a drying process control method provided by an embodiment of the present invention. As shown in FIG. 1 , the drying process control method provided by the present application includes the steps of:

S0. After the drying process starts, it is judged whether the drying process is finished or the power is turned off. If the two conditions satisfy one condition, the drying process is ended; otherwise, step S1 is performed.

S1. At any time during the drying process, the main controller determines whether the door of the washer/dryer is opened, and if so, performs step S2.

In the washing and drying machine, the drying process needs to operate the start/pause button. When it is judged that the temperature inside the drum does not cause the human body to feel uncomfortable, the door lock is opened and the door body is opened; in the dryer, the door body can also be directly Pulled open manually by the user. Both of these situations are understood to be the opening of the door.

S2. The main controller controls the drying program to pause, and displays a selection prompt of “end drying/continuing drying” or a similar selection prompt on the operation panel.

S3. The main controller determines whether "continue drying" is selected within the set time T1, and if "continue drying" is selected, preferably, step S4' is performed.

S4', detecting whether the door body is closed within the set time T2, if the door body has been closed within the set time T2, executing step S5; if the door body has not been closed within the set time T2, then End the program directly.

S5. The main controller determines whether the drying program is reset. If the drying program is not reset, step S6 is performed; otherwise, step S7 is performed.

S6. After waiting for the door body to be closed, the heating component and the dehumidifying component of the dryer will be sequentially opened according to the normal drying process, and the main controller controls the washing/drying machine to continue to operate according to the original drying procedure.

With this method, the user only needs to choose to continue to dry. After the door body is closed, it is not necessary to operate the start button again, that is, it can be operated according to the original drying program, and the subsequent prompt selective operation can omit the operation and prevent the operation from being caused to the user. Trivial.

In the present embodiment, in step S3, if "end drying" is selected or there is no response within the set time T1, the main controller controls the end of the drying process. If the user opens the door and inspects the dryness of the clothes to the expected level, it may only take the clothes away, ignoring the closing and further operation of the equipment. Therefore, the washer/dryer needs to automatically end the drying process and turn off the power.

In this embodiment, as a preferred solution, if you choose to continue drying, you can also run the next step. The drying program is reset. Therefore, after step S3, the following steps are also set:

Wherein, step S4 can be performed after the door body is closed and the drying process is restarted. At this time, if the drying process is changed, the drying program is operated according to the change. Step S4 may also occur before the door body is closed, that is, after the drying program is re-modified, the door body is closed, and the drying program is operated according to the change.

Of course, after the user chooses to continue drying, the subsequent settings (step S4) may be ignored. If the subsequent settings (step S4) are ignored, the user still operates according to the original drying program.

Specifically, step S4 includes the following steps:

S41. The main controller determines whether the drying program is in the drying stage when the door of the washer/dryer is opened or in the shaking stage of preventing the wrinkles of the clothes. If it is in the drying stage, step S42 is performed.

S42. The main controller controls the operation panel to display a selection prompt of “whether to take out/put some clothing”.

In the first half of drying, especially in the beginning of drying, the user opens the door more to re-insert or take out some of the clothes to match the amount of clothing that the user feels is conducive to drying or to forget to put in. Take out clothes that do not need to be dried.

S43. The main controller responds to the instruction information input by the user from the operation panel. If the user selects No in the selection prompt of “whether the part is taken out/inserted”, the process proceeds to step S5, that is, the drying process is performed according to the original drying program. The setting is made; if yes, step S45 is performed.

For the washing and drying machine, when the clothes are dry, the temperature value or the temperature change rate of the different clothes weights is different, or the perceived humidity is different. In order to judge the clothes drying procedure more accurately, the weight of the clothes needs to be re-metered and corrected. Of course, when the degree of dryness is different, the correction coefficient of the weight after opening the door is different. The higher the degree of drying, the closer the weight of the laundry calculated using the motor parameters is to the actual value, and the smaller the corrected value.

In the present embodiment, as a preferred solution, in step S41, if the washing and drying machine or the dryer is in the shaking phase, step S46 is performed.

S46. The main controller controls the operation panel to display a selection prompt of “setting the drying time/removing part of the clothing”.

S47. The main controller responds to the instruction information input by the user from the operation panel. If the user selects “set time” for the selection prompt “set drying time/whether part of clothing has been taken out”, step S48 is performed; if "Whether a part of the clothes has been taken out", step S49 is performed.

S48. The drying process is reset according to the drying condition corresponding to the drying time set by the user, and then step S7 is performed until the end.

S49. The main controller controls a selection prompt of “whether a part of the clothes has been taken out” is displayed on the operation panel. If yes is selected for the selection prompt, step S410 is performed; if no is selected, step S411 is performed.

S410, entering the weighing program, re-measuring the weight of the laundry, resetting the drying program according to the drying condition corresponding to the weight of the laundry, and increasing a drying level when determining whether the laundry drying process is finished, and then performing step S7.

In the shaking phase, the drying process of the laundry has ended, and the user chooses to continue drying to indicate that the user is not satisfied with the dryness of part of the laundry, so it is necessary to strengthen the drying of some or all of the laundry.

The user chooses to continue to dry, indicating that the user is not satisfied with the dryness of some of the clothes. Judging according to the original judgment of drying conditions may also cause the user's dissatisfaction, so it is necessary to slightly lower the moisture content after drying as a criterion for judging drying. In order to achieve the degree of dryness of the user's psychological expectations.

Therefore, in the present embodiment, in step S410 or step S411, it is determined whether the temperature of the outlet of the heating pipe rises by more than 3 ° C in 10 minutes by increasing the drying level. The original drying level may be to determine whether the temperature of the outlet of the heating pipe rises by more than 2 degrees within 10 minutes.

Since the washing and drying machine or the dryer door is opened and needs to continue to dry, a selection prompt is displayed on the operation panel, and the user can conveniently reset the drying program according to the selection prompt.

The present application also provides a washing and drying machine that uses the drying process control method described above.

The present application also provides a clothes dryer that uses the drying process control method described above.
