Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
The embodiment of the invention provides a control method of a clothes treatment device, wherein the clothes treatment device can be a washing machine or a washing and drying integrated machine with a drying function, and as shown in fig. 1, the clothes treatment device can comprise a box body 1 and a washing barrel 2 arranged in the box body, and the washing barrel 2 is provided with an opening for putting clothes; the box body 1 can be provided with a safety switch 11 and a pressure sensing switch 12, the safety switch 11 is used for triggering safety protection under the impact of the washing barrel 2, and the pressure sensing switch 12 is used for detecting the impact pressure of the washing barrel 2. For example, during the dehydration of the washing tub 2, the safety switch 11 may be bumped due to the influence of the laundry eccentricity, thereby triggering the safety protection, and at this time, the pressure sensing switch 12 may detect the bumped pressure of the washing tub 2.
As shown in fig. 2, a control method of a laundry treating apparatus according to an embodiment of the present invention includes:
step 201, acquiring a pressure value corresponding to triggering safety protection of clothes treatment equipment in a dehydration process;
step 202, determining a deviation correcting rinsing time period required for correcting the eccentricity based on the pressure value.
Here, the pressure value is positively correlated with the laundry eccentricity amount of the laundry treating apparatus. Here, the positive correlation means that the pressure value increases as the laundry eccentricity increases, and decreases as the laundry eccentricity decreases. Therefore, the clothes treatment equipment can dynamically adjust the deviation rectifying and rinsing time based on the clothes eccentric quantity of the clothes treatment equipment, and further effectively improve the deviation rectifying effect in the dehydration process.
Illustratively, the acquiring the pressure value corresponding to triggering the safety protection of the laundry treatment apparatus during the dehydration process includes:
determining that a safety switch of the laundry treating apparatus is triggered during dehydration, determining the pressure value based on an electrical signal generated by a pressure-sensing switch of the laundry treating apparatus.
It will be appreciated that during the dehydration process, if the washing tub 2 hits the safety switch 11 on the cabinet 1, the safety protection is triggered, and the laundry treating apparatus may determine the pressure value corresponding to the hit based on the electric signal generated by the pressure sensing switch 12. In order to ensure that the pressure sensing switch 12 can detect the striking pressure of the washing tub 2, the distance between the pressure sensing switch 12 and the washing tub 2 may be smaller than the distance between the safety switch 11 and the washing tub 2. In an application example, the pressure-sensitive switch 12 includes a pressure-sensitive resistor, and the laundry treating apparatus may determine the pressure value based on an electrical signal generated by a pressure-sensitive sensor (e.g., a pressure-sensitive resistor), which may be positively correlated with the pressure value.
The deviation correcting rinsing time period is positively correlated with the current pressure value, namely when the pressure value is larger, the eccentric quantity of the clothes can be judged to be larger, and the corresponding deviation correcting rinsing time period is prolonged; when the pressure value is smaller, the fact that the eccentric quantity of the clothes is smaller can be judged, and the corresponding deviation correcting rinsing time is shortened.
In an application example, the determining the corrective rinse time period required to correct the eccentricity based on the pressure value includes:
if the pressure value is smaller than a first pressure threshold value, determining that the deviation correcting rinsing time length is a first time length; or,
if the pressure value is greater than or equal to the first pressure threshold value and less than the second pressure threshold value, determining that the deviation correcting rinsing time period is a second time period; or,
if the pressure value is greater than or equal to the second pressure threshold value and less than the third pressure threshold value, determining that the deviation correcting rinsing time period is a third time period; or,
if the pressure value is greater than or equal to the third pressure threshold value and less than the fourth pressure threshold value, determining that the deviation correcting rinsing time period is a fourth time period; or,
if the pressure value is greater than or equal to a fourth pressure threshold value, determining that the deviation correcting rinsing time length is a fifth time length;
the first pressure threshold value is smaller than the second pressure threshold value is smaller than the third pressure threshold value is smaller than the fourth pressure threshold value, and the first time period is smaller than the second time period, the third time period is smaller than the fourth time period, and the fifth time period is smaller than the fourth time period.
Therefore, the clothes treatment equipment can dynamically adjust the deviation correcting rinsing time based on the pressure value corresponding to the triggering safety protection, so that the deviation correcting rinsing time is adapted to the current clothes eccentric amount, and the deviation correcting effect in the dehydration process can be improved.
Illustratively, the determining a corrective rinse time period required to correct the eccentricity based on the pressure value includes:
determining that the statistical times reach or exceed a first set time and are smaller than a second set time, wherein differences larger than or equal to a set threshold exist in differences between a pressure value obtained for the first time and each pressure value obtained for the subsequent time in the dehydration process, or determining that the statistical times are smaller than the first set time, and determining deviation correcting rinsing time required for correcting eccentricity based on the current pressure values;
the counted times are counted triggering times of the safety protection or execution times of deviation correcting rinsing, and the first set times are smaller than the second set times. The first setting times and the second setting times can be reasonably set according to requirements.
It can be appreciated that if the counted number is smaller than the first set number, determining the deviation correcting rinsing time required for correcting the eccentricity directly based on the current pressure value; if the counted times reach or exceed the first set times and are smaller than the second set times, comparison judgment is needed according to the difference value between the first acquired pressure value and the later acquired pressure value and the set threshold value, if the later acquired pressure value is gradually declining, the difference value between the first acquired pressure value and the later acquired pressure value is larger and larger, if at least one difference value larger than the set threshold value exists in the difference values, the deviation correcting rinsing can effectively improve the eccentricity of clothes, and the deviation correcting rinsing can be continued.
In some embodiments, the control method further comprises:
and determining that the statistical times reach or exceed the first set times and are smaller than the second set times, wherein the difference value between the pressure value obtained first and the pressure value obtained later in the dehydration process is smaller than a set threshold value, or determining that the statistical times reach the second set times, stopping dehydration and generating an alarm signal for manual deviation correction.
It can be understood that if the counted times reach the second set times, an alarm signal is directly generated to remind the user to correct the deviation manually; if the counted times reach or exceed the first set times and are smaller than the second set times, comparison judgment is needed according to the difference value of the first acquired pressure value and the later acquired pressure value and a set threshold value, if the difference value of the first acquired pressure value minus the later acquired pressure value becomes smaller or a negative value appears, the deviation correcting rinsing is indicated to not effectively improve the eccentricity of the clothes, namely if the difference value of the first acquired pressure value and the later acquired pressure value is smaller than the set threshold value, an alarm signal is directly generated to remind the user to correct the clothes manually.
In an application example, the statistical number refers to the triggering number of the safety protection or the execution number of the deviation correcting rinsing corresponding to the current dehydration program stage, and if the current dehydration program is finished, the statistical number is cleared to be counted again when the next dehydration program is started. In another application example, the counted number of times may be the counted number of triggers of the safety protection or the counted number of times of execution of the corrective rinsing after the laundry treating apparatus is powered on.
Therefore, the frequency of rectifying and rinsing in the dehydration process can be reasonably controlled, and under the condition that the rectifying and rinsing are ineffective for many times, the user is prompted to conduct manual rectifying through the alarm signal, so that subsequent clothes treatment is conducted after the manual rectifying.
Illustratively, the control method of the laundry treating apparatus further includes:
and carrying out deviation correcting rinsing based on the deviation correcting rinsing time length, and continuing to dewater after the deviation correcting rinsing.
Here, the laundry treating apparatus may perform the corrective rinsing based on the determined corrective rinsing time period to correct the eccentricity and continue the current dehydration after the corrective rinsing. The correcting and rinsing can be that the correcting and rinsing is carried out based on the correcting and rinsing time after the clothes treatment equipment is supplemented with water to the set water level. It can be understood that if the collision of the washing barrel to the safety switch still occurs to trigger the safety protection in the subsequent dehydration process, the pressure value corresponding to the current safety protection is continuously obtained, and the deviation correcting rinsing time length required for correcting the eccentricity is determined based on the pressure value.
Embodiments of the present invention are described in further detail below in conjunction with an application example.
