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 method for determining clogging of a lint filter, in which an automatic weighing device is disposed on the lint filter, so that a clogging degree of the lint filter can be determined according to a weight variation value of the lint filter. Along with the use of line bits filter, the accumulational line bits can be more and more in the line bits filter, consequently can cause the weight of line bits filter to increase gradually, and consequently this kind of judgement method is direct accurate, in the use, can monitor the weight of line bits filter in real time, and the judgement time is short to and remind the user to clear up or change in time.
When the whole machine starts to be used, recording the initial weight of the thread scrap filter; after the initial weight of the thread scrap filter is obtained, comparing the initial weight with a preset weight, if the initial weight exceeds the preset weight, indicating that the thread scrap filter is not cleaned, and prompting a user to treat; if the initial weight does not exceed the preset weight, the operation can be continued, and the weight change value of the thread dust filter is monitored.
Because the filtering capacity of the thread scrap filter is limited, if the thread scrap filter is not cleaned in the initial stage, the thread scrap filter is blocked in a short time easily in the using process, and the normal operation of the whole machine is influenced. Since the initial weight of the lint filter is different for different models, the preset weight may be set according to actual conditions, and is not limited herein. The way of prompting the user to perform the processing may be flashing an indicator light, voice prompt, etc., and is not limited herein.
In the using process, the current weight of the lint filter is monitored in real time, the difference value between the current weight and the initial weight is a weight change value, and the blockage degree of the lint filter is judged according to the comparison between the weight change value and a preset value. The preset value is pre-stored in the whole machine, can be one or a plurality of, and the blockage degree of the thread scrap filter can be judged according to the range of different weight change values by comparing the current weight change value with the preset value, so that corresponding treatment measures are taken.
In this embodiment, if the weight variation value is lower than the first preset value, it indicates that the lint in the lint filter is less accumulated, and the lint filter is in a normal filtering state, and the lint filter is considered to be not blocked; if the weight change value is between the first preset value and the second preset value, a certain amount of thread scraps are accumulated in the thread scraps filter, but the normal work of the thread scraps filter is not influenced, and the thread scraps filter is considered to be slightly blocked; if the weight change value is higher than the second preset value, the weight change value indicates that a large amount of thread scraps are accumulated in the thread scraps filter, the normal work of the thread scraps filter is influenced, and the thread scraps filter is considered to be seriously blocked. The first preset value and the second preset value may be set according to actual conditions, and are not limited herein. Of course, a third preset value and a fourth preset value, which are different from the first preset value and the second preset value, may also be set, so as to divide the clogging degree of the lint filter in more detail, and further description is omitted here.
After the clogging degree of the lint filter is judged, corresponding treatment measures can be taken. If the weight change value is lower than the first preset value, the thread scrap filter is not blocked and can continue to operate without treatment; if the weight change value is between the first preset value and the second preset value, the thread scrap filter is slightly blocked, an alarm prompt can be given, and a user can clean the thread scrap filter in time; if the weight change value is higher than the second preset value, the lint filter is seriously blocked, and the machine can be directly stopped, so that other parts are prevented from being damaged due to the blockage of the lint filter. The above processing measures can be set according to actual conditions, and are not limited herein.
In the process of monitoring the weight change value of the thread scrap filter, monitoring whether the running time reaches the set running time in real time, and if so, stopping the whole machine; otherwise, the operation is continued, and the weight change value of the thread scrap filter is monitored. The operation of the whole machine is generally set with a set operation time, which is the longest time for the whole machine to execute a certain program, such as the washing time and the rinsing time of a washing machine, the drying time of a drying machine and the like, and if the operation time reaches the set operation time, the whole machine stops operating.
If the weight variation value is higher than the second preset value, the machine is stopped, and the possibility of misjudgment exists, so that the normal operation is influenced, and the time is wasted. In this embodiment, therefore, the duration monitoring is added to the weight change value, and the weight change value is matched with the duration to determine the treatment to be taken.
If the weight change value reaches a first preset value, triggering a first timer to start timing; and if the weight change value reaches a second preset value, triggering a second timer to start timing, and stopping timing by the first timer. By means of the first timer and the second timer, the time for the weight variation value to reach the first preset value and the second preset value can be determined, and the duration of the weight variation value between the first preset value and the second preset value can be determined. And if the weight change value reaches a second preset value when the monitoring is started, triggering a second timer to start timing, wherein the first timer is not triggered.
If the duration of the weight change value between the first preset value and the second preset value is too long, the drying efficiency may be affected, and therefore if the first timer starts timing, a primary alarm prompt is performed; and if the timing time of the first timer is higher than the first preset time, performing intermediate-level alarm prompting. The first preset time is not limited and can be set according to actual conditions.
If the weight change value is longer than the second preset value, other parts may be damaged due to serious blockage of the thread scrap filter, and therefore if the second timer starts to time, high-grade alarm prompt is carried out; and if the timing time of the second timer is higher than the second preset time, stopping the whole machine. The second preset time is not limited and can be set according to actual conditions.
In this embodiment, the primary alarm prompt includes at least flashing of the indicator light, the intermediate alarm prompt includes at least voice playing, the intermediate alarm prompt may be a combination of flashing of the indicator light and voice playing, the advanced alarm prompt includes at least turning on of the buzzer, and the advanced alarm prompt may be a combination of flashing of the indicator light and turning on of the buzzer. The alarm prompt is not limited and can be set according to actual conditions.
The embodiment of the invention also provides a clothes dryer, which is controlled by adopting the method for judging the blockage of the lint filter. The lower part of the on-line scrap filter is provided with an automatic weighing device, the automatic weighing device is connected with a control panel of the clothes dryer, and the acquisition signals of the automatic weighing device are processed through an acquisition circuit in the control panel, so that the display is facilitated. The automatic weighing machine can be interfered by fluid during the working process, and interference signals are filtered by adding filtering processing in a control panel. Of course, the clothes dryer further comprises the first timer and the second timer, and the first timer and the second timer are both connected with the control panel.
