Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
Referring to fig. 1 and 2, an embodiment of the present invention provides a washing machine, including a drain pump 1, a water inlet end of the drain pump 1 is connected to an outer tub of the washing machine through a water inlet pipe 2, and a water outlet end of the drain pump 1 is communicated with the outside through a water outlet pipe 3.
The washing machine further comprises a turbidity sensor 4, a flow sensor 5 and a temperature sensor 6, wherein the turbidity sensor 4 is arranged at the water inlet end of the drainage pump 1 and is used for acquiring the current turbidity value of the washing water; the flow sensor 5 is arranged at the water outlet end of the drainage pump 1 and used for acquiring the drainage flow value of the drainage pump 1; the temperature sensor 6 is disposed on the drain pump 1 and is configured to obtain a current temperature value of the drain pump 1.
The washing machine further comprises a controller, wherein the drainage pump 1, the turbidity sensor 4, the flow sensor 5 and the temperature sensor 6 are electrically connected with the controller, the turbidity sensor 4, the flow sensor 5 and the temperature sensor 6 can transmit detection signals to the controller, and the controller can control the drainage pump 1 to be turned on or off.
Referring to fig. 3, the washing machine further includes a drain branch pipe 7 and a drain valve 8, one end of the drain branch pipe 7 is communicated with the water inlet pipe 2, the drain valve 8 is disposed at a junction of the drain branch pipe 7 and the water inlet pipe 2, the other end of the drain branch pipe 7 is communicated with the drain pipe 3, the drain valve 8 is electrically connected to the controller, and a drain path can be changed by controlling the opening and closing of the drain valve 8. When the drainage pump 1 is closed and the drainage valve 8 is opened, water in the outer barrel enters the drainage branch pipe 7 through the water inlet pipe 2 and is discharged from the drainage pipe 3, sewage cannot pass through the drainage pump 1, and impurities cannot block the drainage pump 1.
Example one
Referring to fig. 4, an embodiment of the present invention provides a drain control method for a washing machine, which is used for controlling the washing machine.
The washing machine drainage control method comprises the following steps:
before draining, acquiring a current turbidity value of the washing water;
if the current turbidity value is not greater than the set turbidity value, the controller controls the drainage pump 1 to be started for drainage;
if the current turbidity value is larger than the set turbidity value, the controller controls the drainage pump 1 to be closed and outputs first alarm information.
The turbidity value can reflect the dirty degree of the washing water, and according to the detection principle, when more impurities are contained in the washing water, the turbidity can be obviously increased, so that the amount of the impurities in the washing water can be judged according to the change of the turbidity value, and therefore, a user can be warned and corresponding measures can be taken in time to prevent the damage of the drainage pump 1.
The set turbidity value is stored in the controller, the turbidity sensor 4 acquires the current turbidity value of the washing water and transmits a signal to the controller, and the controller compares the current turbidity value with the set turbidity value.
If the current turbidity value is not larger than the set turbidity value, the impurities in the washing water cannot block the drainage pump 1, and at the moment, the drainage pump 1 can be adopted for drainage, and the controller controls the drainage pump 1 to be started for drainage.
If the current turbidity value is larger than the set turbidity value, the fact that the impurities in the washing water are more and exceed the discharge capacity of the drainage pump 1, the drainage pump 1 is blocked, and then the controller controls the drainage pump 1 to be closed and outputs first alarm information.
Wherein, first alarm information is exported by the controller, and first alarm information can include text message and sound information, and specifically, text message can show on washing machine's display screen, and sound information is convenient for arouse the user to notice to in time learn washing machine's drainage state. Alternatively, the textual information may be "more impure".
Optionally, the text message may be displayed on a mobile terminal of the user, for example, a mobile phone APP, so that the user can know the drainage state of the washing machine in time when the user is not near the washing machine.
After outputting the first alarm information, the controller controls the drain valve 8 to open, and the washing water flows to the drain pipe 3 through the drain valve 8 and is discharged. The washing water does not flow through the drain pump 1 and thus does not cause clogging of the drain pump 1.
In the case where the current turbidity value is not greater than the set turbidity value, the drain pump 1 is normally turned on.
Referring to fig. 5, when the drain pump 1 is turned on, a time is counted, a drain flow value of the drain pump 1 is obtained during the draining process of the drain pump 1, and the operation state of the drain pump 1 is determined according to the drain flow change in different time periods.
The operation state of the drain pump 1 includes a normal operation state and a malfunction state, wherein the malfunction state includes a filter screen clogging and a drain pump 1 breakdown. When the filter screen is blocked, the drainage flow can be reduced, and the drainage pump 1 runs normally without damage. When the drain pump 1 is damaged, the fan blades of the drain pump 1 are locked, and the temperature of the drain pump 1 is obviously increased.
In general, the flow rate of the discharged water is large in the initial stage of the discharge, and the flow rate of the discharged water gradually decreases as the water level in the outer tub decreases as the water is discharged to the outside. For the convenience of control, the drainage process may be divided into different periods, each having a corresponding reference value. In the present embodiment, the drainage process is divided into three periods.
In the first period of water drainage, if the drainage flow value is smaller than the first set flow value, the controller controls the drainage pump 1 to stop working and outputs second alarm information. If the drainage flow value is not less than the first set flow value, the drainage is continued.
And in the second period of the drainage, if the drainage flow value is smaller than a second set flow value, the controller controls the drainage pump 1 to stop working and outputs second alarm information. If the drainage flow value is not less than the second set flow value, the drainage is continued.
In the third period of the drainage, if the drainage flow value is smaller than the third set flow value, the controller controls the drainage pump 1 to stop working. Here, the third set flow rate value is close to 0, which indicates that the water discharge is completed. If the drainage flow value is not less than the third set flow value, the drainage is continued until the drainage flow value is less than the third set flow value.
Wherein, the drainage pump 1 is controlled to stop working, namely, the drainage pump 1 is powered off. The second alarm information is output by the controller, and the second alarm information may include text information and sound information, specifically, the text information may be displayed on a display screen of the washing machine or on a mobile terminal of a user, and the sound information is convenient for attracting the attention of the user so as to be processed in time. Alternatively, the text message may be "drainage failure".
Wherein, the drainage fault may be the filter screen blockage or the damage of the drainage pump 1.
After the second alarm information is output, the controller controls the drain valve 8 to be opened, and the washing water flows to the drain pipe 3 through the drain valve 8 to be discharged. The washing water does not flow through the drain pump 1, and thus the drainage can be smoothly completed, and the user can timely handle the malfunction.
Referring to fig. 6, in order to more accurately determine the type of the fault, after the second alarm information is output, the current temperature value of the drain pump 1 is obtained, if the current temperature value is within the set temperature range, the third alarm information is output, otherwise, the fourth alarm information is output.
The third alarm information is output by the controller, the third alarm information may include text information and sound information, specifically, the text information may be displayed on a display screen of the washing machine or on a mobile terminal of a user, and the sound information is convenient for the user to pay attention to so as to be processed in time. Alternatively, the text message may be "filter screen clogged".
The fourth alarm information is output by the controller, the fourth alarm information may include text information and sound information, specifically, the text information may be displayed on a display screen of the washing machine or on a mobile terminal of a user, and the sound information is convenient for the user to pay attention to so as to be processed in time. Alternatively, the literal message may be "the drain pump 1 is damaged".
The staff can carry out the pertinence maintenance according to different alarm information.
The embodiment of the invention integrates water quality monitoring and drainage pump running state monitoring, feeds back the drainage state to the controller of the washing machine in real time, can feed back data to the cloud server for analysis, and can feed back an analysis result to the user APP to remind the user of the current running state of the washing machine, thereby avoiding the drainage abnormal risk. From the household electrical appliances maintenance angle, combine wisdom thing allies oneself with, realize the unusual quick early warning of drainage and solve.
Example two
Referring to fig. 7, the embodiment of the present invention provides a method for controlling drainage of a washing machine, and for the sake of simplicity, only the differences between the second embodiment and the first embodiment will be described. The difference is that the current temperature value of the drainage pump 1 is obtained in the drainage process of the drainage pump 1, and if the current temperature value is not within the set temperature range, fourth alarm information is output. Whether the drain pump 1 is damaged or not can be judged according to the temperature, so that the drain pump can be timely treated. If the operation state of the drainage pump 1 is judged only according to the flow value, the following disadvantages exist: when the drain pump 1 is in failure and leaks, there is a drain flow value, but the failure state cannot be detected in time.
In the working process of the drainage pump 1, the drainage pump 1 emits heat, the temperature of the drainage pump 1 is higher than the normal temperature, and under the normal condition, the temperature of the drainage pump 1 fluctuates within a certain range; when the drain pump 1 malfunctions, the temperature of the drain pump 1 may significantly increase. The fourth alarm information is the same as the first embodiment.
The set temperature range is between a first set temperature value and a second set temperature value, the first set temperature value is higher than the normal temperature, and the second set temperature value is higher than the first set temperature value. If the current temperature value is lower than the first set temperature value or higher than the second set temperature value, the current temperature value is out of the set temperature range. The current temperature value is lower than the first set temperature value, which indicates that the drainage pump 1 stops working, and the current temperature value is higher than the second set temperature value, which indicates that the drainage pump 1 blocks the rotation.
After outputting the fourth warning information, the controller controls the drain valve 8 to open, and the washing water flows into the drain pipe 3 through the drain valve 8 to be discharged. The staff can carry out the pertinence maintenance according to fourth alarm information.
When the drainage pump 1 is started, timing is carried out, the current temperature value and the drainage flow value of the drainage pump 1 are obtained in the drainage process of the drainage pump 1, and if the current temperature value is within a set temperature range, the running state of the drainage pump 1 is judged according to the drainage flow change in different time periods.
In the first period of water drainage, if the drainage flow value is smaller than the first set flow value, the controller controls the drainage pump 1 to stop working and outputs third alarm information. If the drainage flow value is not less than the first set flow value, the drainage is continued.
And in the second period of the drainage, if the drainage flow value is smaller than the second set flow value, the controller controls the drainage pump 1 to stop working and outputs third alarm information. If the drainage flow value is not less than the second set flow value, the drainage is continued.
In the third period of the drainage, if the drainage flow value is smaller than the third set flow value, the controller controls the drainage pump 1 to stop working. Here, the third set flow rate value is close to 0, which indicates that the water discharge is completed. If the drainage flow value is not less than the third set flow value, the drainage is continued until the drainage flow value is less than the third set flow value.
Wherein, the drainage pump 1 is controlled to stop working, namely, the drainage pump 1 is powered off. The third alarm information is output by the controller, and the third alarm information may include text information and sound information, specifically, the text information may be displayed on a display screen of the washing machine or on a mobile terminal of a user, and the sound information is convenient for the user to pay attention to so as to be processed in time. Alternatively, the text message may be "filter screen clogged".
After the third alarm information is output, the controller controls the drain valve 8 to be opened, and the washing water flows to the drain pipe 3 through the drain valve 8 to be discharged. The staff can carry out the pertinence maintenance according to third alarm information.
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.
