Above-mentioned scheme is passed through to this embodiment, current water level in the water storage tank through detecting the water purifier, when the water level is less than preset water level threshold value, control pours into the purified water into in the water storage tank into, so that the water level of purified water in the water storage tank constantly risees, when the user need use directly drinking water, utilize the purified water of high water level in the water storage tank, extrude the straight drinking water in the water bag outside tap, thereby realized not needing to utilize the water pump to drive and just extrude straight drinking water, consequently, the cost of water purifier has been reduced.
Based on the hardware structure, the embodiment of the control method of the water purifier is provided.
Referring to fig. 3, fig. 3 is a schematic flow chart of a first embodiment of a control method of a water purifier according to the present invention.
In a first embodiment, the control method of the water purifier includes the steps of:
step S10, detecting the current water level in a water storage tank of the water purifier, wherein the water storage tank is used for storing purified water generated by the water purifier during operation, a water bag of the water purifier is used for storing generated direct drinking water, and the water bag is arranged in the water storage tank;
in this embodiment, when the user need make straight drinking water and use the straight drinking water that the water purifier made through the water purifier, at first open the water purifier, control water purifier operation system water mode. When the water purifier operates the water making mode, the water purifier performs water making operation to generate direct drinking water, and the generated direct drinking water is injected into the water bag of the water purifier. For example, as shown in fig. 2, the water purifier is operated in a water preparation mode by controlling to open a normally closed water inlet valve 10, a booster pump 20, a normally closed solenoid valve 40 and a normally open solenoid valve 50 of the water purifier and close a flushing solenoid valve 30 of the water purifier, and tap water is filtered by a PAC filter element 70 and an RO membrane filter element 80 to generate drinking water for a user and purified water for cleaning. Wherein, the direct drinking water generated after filtering is injected into the water bag in the water storage tank 100 of the water purifier, and the purified water generated after filtering enters the water storage tank 100 through the normally open solenoid valve 50. Therefore, the drinking water is continuously stored in the water bag, and simultaneously, the purified water is continuously stored in the water storage tank 100.
Further, whether the water purifier operates in the water making mode can be controlled by detecting the open/close state of the pressure switch 60. Specifically, when the pressure switch 60 is detected to be closed, it is indicated that the direct drinking water in the water bag is insufficient, and at this time, the water purifier is controlled to operate the water preparation mode, the normally closed water inlet valve 10, the booster pump 20, the normally closed solenoid valve 40 and the normally open solenoid valve 50 of the water purifier are opened, and the flushing solenoid valve 30 of the water purifier is closed, so that the water preparation operation is performed. Therefore, the water purifier can automatically perform water preparation operation by detecting the open/close state of the pressure switch 60.
Because the pressure switch 60 is automatically switched off when the water bag is filled with direct drinking water, whether the water bag is filled with direct drinking water can be judged by detecting the opening and closing state of the pressure switch 60. Specifically, when the pressure switch 60 is detected to be closed, it is indicated that the water bag is not filled with direct drinking water, and at this time, the water purifier is controlled to continue to operate the water making mode to generate direct drinking water. Until the pressure switch 60 is detected to be switched off, the water bag is indicated to be filled with direct drinking water, and at the moment, the direct drinking water is stopped being filled into the water bag.
After the water bag is filled with direct drinking water, in order to press the direct drinking water in the water bag out to the corresponding faucet, in this embodiment, the purified water is continuously injected into the water storage tank 100. For example, as shown in fig. 2, the water purifier is controlled to close the booster pump 20 and continue to control the normally closed water inlet valve 10, the normally closed solenoid valve 40 and the normally open solenoid valve 50 of the water purifier to open, and the flushing solenoid valve 30 of the water purifier is closed, so that more and more purified water is stored in the water storage tank 100, and the water level of the purified water in the water storage tank 100 is continuously raised. When the purified water in the water storage tank 100 is full, it is discharged through the normally closed solenoid valve 40 and the flushing solenoid valve 30.
When the water level of the purified water in the water storage tank 100 reaches a certain height, when the tap corresponding to the direct drinking water is opened, the purified water with the high water level in the water storage tank 100 is utilized to press the direct drinking water in the water bag out of the tap, so that the user can use the water. Therefore, in order to utilize the purified water in the water storage tank 100 to press out the direct drinking water in the water bag, in this embodiment, the current water level of the purified water in the water storage tank 100 is detected in real time or at regular time. Optionally, the water shortage detection device 110 is used to detect the current water level of the purified water in the water storage tank 100 in real time or at regular time, so as to determine whether the water storage tank 100 is short of water currently.
And step S20, when the water level is lower than a preset water level threshold value, controlling to inject purified water into the water storage tank so as to enable the water level of the purified water in the water storage tank to be continuously raised, and when a tap corresponding to direct drinking water is opened, utilizing the purified water with high water level in the water storage tank to press out the direct drinking water in the water bag.
In this embodiment, a preset water level threshold for determining whether the water storage tank 100 is short of water is preset. After detecting the current water level of the purified water in the water storage tank 100 through the water shortage detection device 110 of the water storage tank, comparing the detected water level with a preset water level threshold value, if the detected water level is higher than the preset water level threshold value, it is sufficient to explain that the purified water in the water storage tank 100 is sufficient, and the purified water stored currently in the water storage tank 100 is utilized, so that the direct drinking water in the water bag can be pressed out of the faucet. If the detected water level is lower than the preset water level threshold, it indicates that the purified water in the water storage tank 100 is insufficient, and at this time, the purified water is controlled to be injected into the water storage tank 100. For example, in the water purifier shown in fig. 2, the normally closed water inlet valve 10 and the normally open solenoid valve 50 are controlled to be opened, and the booster pump 20, the flushing solenoid valve 30 and the normally closed solenoid valve 40 are controlled to be closed, so that purified water is injected into the water storage tank 100, and the level of the purified water in the water storage tank 100 is continuously increased.
Along with the water level of the purified water in the water storage tank 100 is continuously raised, when a tap corresponding to the direct drinking water is opened, the purified water with high water level in the water storage tank 100 is utilized, and the direct drinking water in the water bag can be pressed out of the tap, so that the water can be used by a user. That is, this embodiment has realized not needing the water pump to drive, just extrudes the effect of straight drinking water, consequently, greatly reduced the cost of water purifier to, owing to need not install the water pump, also practiced thrift the space.
The scheme that this embodiment provided, current water level in the water storage tank through detecting the water purifier, when the water level is less than preset water level threshold value, control pours into the purified water into in the water storage tank into, so that the water level of purified water in the water storage tank constantly risees, when the user need use directly drinking water, utilize the purified water of high water level in the water storage tank, extrude the straight drinking water in the water bag outside tap, thereby realized not needing to utilize the water pump to drive and just extrude straight drinking water, consequently, the cost of water purifier has been reduced.
Further, as shown in fig. 4, a second embodiment of the method for controlling a water purifier according to the present invention is proposed based on the first embodiment, and in this embodiment, before the step S20, the method further includes:
step S30, acquiring first time required by filling purified water in the water storage tank;
after the step S20, the method further includes:
and step S40, when the time for injecting the purified water reaches the first time, controlling to stop injecting the purified water into the water storage tank.
In this embodiment, the time required for filling the water storage tank 100 with purified water is obtained before the water storage tank 100 is filled with purified water. For convenience of description, the time required for filling the water storage tank 100 with purified water will be hereinafter referred to as a first time. For example, the first time required to obtain the filling of the water storage tank 100 with purified water is calculated by taking the volume of the water storage tank 100 and the rate of filling the water storage tank 100 with purified water. It will be understood by those skilled in the art that the step S30 may be executed before the step S20, after the step S20, or simultaneously with the step S20 and the step S30, and the specific execution sequence of the step S20 and the step S30 is not limited herein.
In the process of injecting purified water into the water storage tank 100, the normally closed water inlet valve 10 and the normally open solenoid valve 50 are controlled to be opened, the booster pump 20, the flushing solenoid valve 30 and the normally closed solenoid valve 40 are closed, the time for injecting the purified water is timed, when the time for injecting the purified water reaches the first time, it is indicated that the water storage tank 100 is filled with the purified water, and at this time, the injection of the purified water into the water storage tank 100 is controlled to be stopped.
Optionally, the step S40 includes:
and step A, controlling to close the normally open electromagnetic valve when the time for injecting the purified water reaches the first time so as to stop injecting the purified water into the water storage tank.
Alternatively, when the time for injecting the purified water reaches the first time, which indicates that the water storage tank 100 is filled with the purified water, at this time, the normally open solenoid valve 50 is controlled to be closed, so that the injection of the purified water into the water storage tank 100 is terminated.
Further, after the step S40, the method further includes:
and B, when the water purifier is detected to run to meet the preset water drainage condition, controlling the purified water in the water storage tank to be drained.
In order to ensure the cleanness and hygiene of the water purifier, the purified water in the water storage tank 100 is drained. Specifically, a drainage condition corresponding to the operation of the water purifier is preset, and when it is detected that the operation of the water purifier satisfies the preset drainage condition, the purified water in the water storage tank 100 is controlled to be drained. For example, a corresponding drain period is previously set, and when it is detected that the operation of the water purifier reaches the preset drain period, the purified water in the water storage tank 100 is controlled to be drained. For example, the normally closed water inlet valve 10, the flushing solenoid valve 30 and the normally closed solenoid valve 40 are controlled to be opened, and the booster pump 20 and the normally open solenoid valve 50 are controlled to be closed, thereby discharging the purified water in the water storage tank 100.
Optionally, before the step B, the method further includes:
step C, acquiring second time required by emptying the purified water in the water storage tank;
the step B comprises the following steps: and when the water purifier is detected to run to meet the preset drainage condition, controlling to open the normally closed water inlet valve, the flushing electromagnetic valve and the normally closed electromagnetic valve, and closing the booster pump and the normally open electromagnetic valve to discharge the purified water in the water storage tank and continue for the second time to empty the purified water in the water storage tank.
Alternatively, in the process of discharging the purified water in the water storage tank 100, the time required for the purified water filled in the water storage tank 100 to be drained is also acquired. For convenience of description, the time required for the water storage tank 100 to be filled with purified water to be emptied will be hereinafter referred to as a second time. For example, by acquiring the volume of the water storage tank 100 and the rate at which the purified water in the water storage tank 100 is drained, the second time required to empty the water storage tank 100 filled with the purified water is calculated.
When it is detected that the operation of the water purifier satisfies the preset drainage condition, the normally closed water inlet valve 10, the flushing solenoid valve 30 and the normally closed solenoid valve 40 are controlled to be opened, and the booster pump 20 and the normally open solenoid valve 50 are controlled to be closed, so that the purified water in the water storage tank 100 is drained and the operation state is continued for a second time. After the second time has elapsed, the purified water in the water storage tank 100 is all emptied. At this time, the flushing solenoid valve 30 and the normally closed solenoid valve 40 are controlled to be closed, the normally open solenoid valve 50 is opened, the normally closed water inlet valve 10 is continuously controlled to be opened, and the booster pump 20 is closed, so that the purified water is continuously injected into the water storage tank 100. After the first time, the water storage tank 100 is filled with purified water, and at this time, the normally open solenoid valve 50 is controlled to be closed, thereby stopping the injection of the purified water into the water storage tank 100.
Further, the control method of the water purifier further includes:
d, recording the water filling times of filling the direct drinking water in the water bag;
the step B comprises the following steps: and when the water full frequency reaches a preset frequency threshold value, controlling to empty the purified water in the water storage tank.
Further, a preset number threshold N is preset, and the preset number threshold N can be flexibly set according to actual conditions, which is not limited herein. After direct drinking water is filled in the water bag each time, the number of times of filling the water bag with direct drinking water is recorded, the number of times of filling the water bag is updated, the current number of times of filling the water bag is compared with a preset number threshold N, if the current number of times of filling the water bag reaches the preset number threshold N, the direct drinking water in the water bag is also described to pass through N full water periods, and at the moment, the purified water in the water storage tank 100 is controlled to be emptied. For example, the normally closed water inlet valve 10, the flushing solenoid valve 30 and the normally closed solenoid valve 40 are controlled to be opened, and the booster pump 20 and the normally open solenoid valve 50 are controlled to be closed, thereby discharging the purified water in the water storage tank 100. Further, the recorded water filling times of filling the direct drinking water in the water bag are reset.
