Detailed Description
In order to make the technical problems solved, the technical solutions adopted and the technical effects achieved by the present invention clearer, the technical solutions of the present invention are further described below by way of specific embodiments with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the elements associated with the present invention are shown in the drawings.
Referring to fig. 1 to 5, an embodiment of the present invention provides a control method for detecting drainage of a washing machine, which starts to time from drainage, records an initial water level, performs water level detection once every preset time interval, compares a current water level with a previous water level, and alarms if a water level variation value is smaller than a constant K.
The detection is carried out once every preset time, so that the detection times are increased, the fault can be found in time, and the long-time waiting is avoided; if the water level changes after the current water level is compared with the previous water level, the water level is drained, and the constant K is set for detecting whether the water drainage quantity is normal or not and preventing the partial blockage of the water drainage pipe.
If the water level change value is not less than the constant K, continuing to drain water and time; the value of K may be different according to different washing machine models, and is not limited herein. In addition, if the water level change value exceeds the set range A, an alarm can be given; similarly, the range A is not limited herein.
Referring to fig. 2, in the drainage process, each time water level detection is performed, the current water level is compared with the reset point water level; if the current water level is lower than the water level of the reset point, comparing the current water level with the water level of the empty barrel; otherwise, continuing to drain. When the current water level is lower than the water level of the reset point, the drainage is close to the tail sound, the water level detection is not needed to be carried out frequently, and only a fixed period of time is needed to be set for drainage.
Draining water for a first set time if the current water level is between the water level of the empty barrel and the water level of the reset point; and if the current water level is lower than the water level of the empty barrel, draining for a second set time. And finishing the drainage after the drainage first set time or the drainage second set time. The duration of the first set time and the duration of the second set time are not limited, and the first set time and the second set time can be set according to actual needs of different machine types so as to ensure that the drainage is sufficient. For example, the first set time may be 60s, and the second set time may be 30s.
Referring to fig. 3, in the draining process of the washing machine, a maximum draining time is set. Namely, when the drain time reaches the maximum drain time, the washing machine automatically stops draining. However, when the washing machine malfunctions, water may remain in the washing machine when the drain time reaches the maximum drain time. Therefore, the time is counted at the start of drainage, and the drainage time is accumulated during drainage, and it is determined whether the accumulated drainage time reaches the maximum drainage time.
If the accumulated drainage time reaches the maximum drainage time, comparing the current water level with the water level at the reset point, and if the current water level is higher than the water level at the reset point, indicating that the water is not drained completely and a fault occurs in the drainage process, alarming. If the current water level is lower than the water level of the reset point, the drainage is considered to be normal; at this time, the drainage can be automatically stopped.
Referring to fig. 4, when the water discharge starts, if the initial water level is higher than the water level at the reset point, the water is discharged by performing the water level detection once every preset time; if the initial water level is lower than the water level of the reset point, the initial water level is low, and at the moment, a fixed period of time can be set for draining. Comparing the initial water level with the water level of the empty barrel, and draining water for a first set time if the initial water level is between the water level of the empty barrel and the water level of the reset point; and if the initial water level is lower than the water level of the empty barrel, draining for a second set time.
Referring to fig. 5, when the washing machine is installed, due to the limitation of indoor space, the size of the drain, or the height of the installation position of the washing machine, the installation condition affects the drainage time when the water is drained. Therefore, in actual use, the drainage time of the washing machine deviates from the drainage time set in the factory test of the washing machine.
In the drainage process of the washing machine, every time water level detection is carried out, the current water level Hi is stored and drainage time Ti from the current water level Hi to the water level of a reset point is accumulated. When the washing machine is used again for draining, detecting an initial water level Hj, comparing the Hj with the last stored water level Hi, and if the difference value is within a set range, acquiring a storage water level Hi corresponding to the initial water level Hj and a drainage time Ti between the storage water level Hi and a reset point water level; otherwise, draining is carried out.
If the washing machine is used for the first time, the water level Hi is not stored for the last time, the water is drained at the moment, the current water level Hi is stored in the draining process, and the draining time Ti from the current water level Hi to the water level of the reset point is accumulated; or, if the washing machine is not used for the first time, but the storage water level Hi corresponding to the initial water level Hj does not exist, draining, storing the current water level Hi in the draining process, and accumulating the draining time Ti from the current water level Hi to the water level of the reset point; and if the stored water level Hi exists, comparing whether Hi compared with the Hj exists or not, specifically, obtaining the difference value between the Hj and the Hi, and if the difference value is within a set range, obtaining the corresponding Hi and the drainage time Ti between the stored water level Hi and the water level at the reset point. The setting range can be set according to actual conditions, and is not limited herein.
After Hi and Ti are obtained, accumulating the drainage time Tj from the initial water level Hj to the water level of a reset point, comparing the Tj with the Ti, and alarming if the difference value is not within a preset range; and if the difference value is within the preset range, continuing draining. The preset range is not limited, and may be set according to actual conditions, for example, the time difference may be within 20 s. When the washing machine leaves a factory and tests, the washing machine needs 2min when the water level is discharged to the reset point water level at the six water levels, and when the washing machine is actually used, the washing machine needs 1.8min when the water level is discharged to the reset point water level at the six water levels, and the water drainage can be considered to be normal. The washing machine has a memory function, and can record the drainage time from a plurality of water levels in the current drainage process and a plurality of corresponding water levels to a reset point. And when the washing machine drainage program is used next time, comparing the current detection value with the last memorized value, if the difference value is within the preset range, indicating that the drainage is normal, and if the difference value is not within the preset range, indicating that the fault exists. Therefore, the drainage control can be performed according to different installation working conditions of each washing machine, and a certain drainage time deviation is allowed, so that the drainage control is more accurate; when the drained water reaches the water level of the reset point, if a fault occurs, the fault can be timely found.
According to this principle, the maximum drain time of the washing machine can also be corrected. In general, for washing machines of different sizes, the drainage time of different water levels is set differently, the drainage time of a large-capacity machine type is set to be 5 minutes of high water level, 4 minutes of middle water level and 3 minutes of low water level, the drainage time of a common large-capacity machine type is set to be 3 minutes of high water level, 2 minutes of middle water level and 1 minute of low water level, and the drainage time of a mini washing machine is set to be 2 minutes of high water level and 1 minute of middle and low water level. For example, the maximum drain time initially set for one washing machine is 8 minutes; when the washing machine is used under the specific working condition of a user, water always remains when the maximum drainage time is reached, and the phenomenon of blockage of a drainage pipe does not exist, so that the drainage is influenced by the size of a drainage channel or the height of the installation position of the washing machine, and the maximum drainage time can be corrected according to actual requirements.
Because the installation working condition of each washing machine is different, the numerical value of K can be obtained through a plurality of experiments after the washing machine is installed, and the accuracy of the K is guaranteed.
The embodiment of the invention also provides the washing machine, and the control method for detecting the drainage of the washing machine is adopted for drainage, so that faults can be found in time, and the time is saved.
The foregoing embodiments are merely illustrative of the principles and features of this invention, which is not limited to the above-described embodiments, but rather is susceptible to various changes and modifications without departing from the spirit and scope of the invention, which changes and modifications are within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
