Detailed Description
So that the manner in which the features and techniques of the disclosed embodiments can be understood in more detail, a more particular description of the embodiments of the disclosure, briefly summarized below, may be had by reference to the appended drawings, which are not intended to be limiting of the embodiments of the disclosure. In the following description of the technology, for purposes of explanation, numerous details are set forth in order to provide a thorough understanding of the disclosed embodiments. However, one or more embodiments may still be practiced without these details. In other instances, well-known structures and devices may be shown simplified in order to simplify the drawing.
FIG. 1 is a flow diagram of a method for controlling a water heater provided by an embodiment of the present disclosure. As shown in fig. 1, an embodiment of the present disclosure provides a method for controlling a water heater including a water drain manifold and a plasma generating device in communication with the water drain manifold, the method comprising:
s201, acquiring the water quality condition in the plasma generating device;
s202, judging whether the water quality condition meets a preset condition; if yes, executing step S203, otherwise executing step S204;
s203, controlling the plasma generating device to discharge plasma water to the water drain header pipe according to the water drain condition of the water drain header pipe;
S204, controlling the plasma generating device to start so that the water quality condition meets the preset condition.
In step S201, the plasma generating device may generate plasma, and the plasma generating device contains moisture, so that plasma water can be formed after the plasma is mixed with the water, and the plasma water contains active components such as H 2O2、O3、NO3 -, OH, and the like, and has a certain pH value range, and has a bactericidal effect. The plasma water can sterilize the water in the water drain main pipe on one hand, and the pH value of the bath water finally formed after the plasma water is diluted by the water in the water drain main pipe on the other hand can make a human body feel comfortable. The water quality condition can be acquired by setting a corresponding detector according to the information to be acquired. For example, when the pH value of the water needs to be obtained, a pH sensor is arranged, and the pH value of the water is obtained through detection data of the pH sensor; when the oxygen content of the water is required to be obtained, an oxygen content measuring instrument is arranged, and the condition of the oxygen content in the water is known according to the detection data of the oxygen content measuring instrument; when the water quantity is required to be obtained, a water level sensor is arranged, the water level condition is known according to the detection result of the water level sensor, and the water quantity is obtained through conversion by combining the specification of the device for storing water in the plasma generating device.
In step S202, the preset condition is a preset requirement for the water quality condition, and the water quality condition is determined based on the preset condition. In step S203, when the water quality condition satisfies the preset condition, it is indicated that the water in the plasma generating device meets the condition of discharging to the water discharge manifold, and on the basis of this, the connection or disconnection between the plasma generating device and the water discharge manifold is controlled according to the water discharge condition of the water discharge manifold. The drainage condition of the drainage manifold comprises at least one of the following: whether the water draining main pipe is in a water draining state; if the drain header is in a drain state, what is the drain flow. If the water drain main pipe is in a water drain state, controlling the plasma generating device to drain plasma water into the water drain main pipe; if the drain manifold is in a non-drain state, the plasma generating device is controlled to be in a non-drain state. The drainage condition of the drainage manifold can be known by arranging a flowmeter, and if the drainage manifold is in a drainage state, the flowmeter can display the corresponding flow. The discharge state of the plasma water in the plasma generating device is related to the water discharge condition of the water discharge main pipe, so that the plasma water can be mixed with the water of the water discharge main pipe when a user uses the water heater, and the water for bathing with uniform and stable comfort is discharged, so that the comfort requirement of the user on the water for bathing is met. In step S204, when the water quality condition does not meet the preset condition, it indicates that the water in the plasma generating device does not meet the condition of discharging to the water drain manifold, and based on this control, the plasma generating device is started to adjust the water quality condition so as to meet the preset condition. By adjusting the water quality, the user can form uniform and stable bathing water when using the water heater.
In some embodiments, the preset conditions include:
The water quantity in the plasma generating device reaches a first preset value; and, in addition, the method comprises the steps of,
The pH of the water in the plasma generating device reaches a second preset value.
The preset conditions include limitation of water quantity, which indicates that the water quantity of the plasma water discharged into the water discharge main pipe needs to meet a certain requirement, if the water quantity of the plasma water is too small, the plasma water can not be continuously discharged into the water discharge main pipe along with the use of a user, and the comfort level of bath water is reduced after the plasma water is discharged completely. The amount of water in the plasma generator can be set according to the capacity of the water tank of the water heater. When the water quantity reaches a first preset value, the plasma water can continuously flow with the water under the drainage state of the drainage main pipe. The first preset value is a water quantity preset value and can be converted into a water level preset value. The actual water level of the plasma water is detected by the water level sensor, and the relation between the actual water level and the water level preset value is judged, so that whether the water quantity reaches the first preset value is determined. Optionally, the water level preset value is L, and L1 is less than or equal to L2. L1 is first water line, L2 is the second water line, and first water line is less than the second water line, compares actual water level with the water level default, and then realizes the judgement to the water yield.
The preset conditions also include limiting the pH value of water, wherein the plasma water contains active ingredients such as H 2O2、O3、NO3 -, OH and the like, has a certain pH value range, and the plasma water meeting the pH value requirement disinfects water in the water draining main pipe when being mixed with water in the water draining main pipe, so that the finally formed bathing water is clean and sanitary. Wherein, the detection of the pH value can be realized by arranging a pH sensor. Optionally, the second preset value is H, and H is more than or equal to 3 and less than or equal to 5. When the pH value of the water in the plasma generating device reaches a second preset value, namely more than or equal to 3 and less than or equal to 5, the water in the water draining main pipe can be sterilized, and the mixed bath water is easy to reach the pH value range which is comfortable for human bodies. The pH value of the water which is comfortable to the human body is 5-6.
Fig. 2 is a flow diagram of a method provided by another disclosed embodiment. As shown in fig. 2, in some embodiments, controlling the activation of the plasma-generating device includes:
s301, controlling the plasma generating device to feed water so as to enable the water quantity to reach a first preset value;
S302, judging whether the water quantity reaches a first preset value; if yes, executing step S303, otherwise executing step S301;
s303, controlling the plasma generating device to generate plasma so that the pH value of water in the plasma generating device reaches a second preset value.
In step S301, the plasma generating apparatus includes a water inlet, and the inflow of water from the water inlet is controlled to reach a first preset value. Optionally, the plasma generating device is provided with a water inlet valve for controlling the on-off of the water inlet valve, the plasma generating device can be made to enter water or stopped from entering water. In step S302, the amount of water is compared with a first preset value. When the first preset value is the preset water quantity and the water quantity reaches the first preset value, the plasma water and the water in the water drainage main pipe can continuously flow in a mixed mode, and therefore the use requirement of a user is met. When the water amount does not reach the first preset value in step S303, controlling the plasma generating device to feed water so as to make the water amount reach the first preset value. For example, when the water amount is lower than the first preset value, the water amount is smaller, and the plasma generating device is controlled to feed water so as to increase the water amount. When the water quantity reaches a first preset value, the water quantity can meet the bath requirement of a user, and the water quantity is not excessive, and at the moment, the pH value of the water can be adjusted. The pH value of the water is the representation of the amount of plasma mixed in the water, if the amount of plasma mixed in the water is insufficient, the plasma device can be controlled to generate plasma, so that more plasma is mixed in the water to reduce the pH value, and the water becomes the plasma water meeting the preset condition requirements. When the water quantity reaches a first preset value and the pH value reaches a second preset value, the water quality condition of the plasma water meets the preset condition and can be discharged into mixed flow in a drainage main pipe.
In some embodiments, controlling the plasma generating device to discharge plasma water to the drain manifold according to a drain condition of the drain manifold includes:
acquiring the flow of water in a drainage main pipe;
And determining the flow rate of the plasma water of the plasma generating device according to the flow rate of the water in the water drain header pipe, and discharging the plasma water to the water drain header pipe.
The flow rate of water in the drain header can be detected by providing a flow meter. When no water flows through the water drainage main pipe, no flow value exists in the flowmeter; the flowmeter is capable of detecting a flow rate value when there is a flow in the drain header. The drainage manifold can also be provided with a flowmeter, the flow rate of water is detected through the flowmeter, and then the flow value is calculated according to the pipe diameter of the drainage manifold. The flow rate of the plasma water of the plasma generating device is related to the flow rate of the water in the water discharging main pipe, so that the plasma water can be mixed into the water in the water discharging main pipe in a certain proportion, the sterilization of the plasma water to the water in the water discharging main pipe can be realized, and the pH value of the mixed bath water can be restored to the range which can be received by a human body and is comfortable. The pH value of the water which is comfortable to the human body is about 5 to 6. Optionally, q2=kxq 1, where Q1 is the flow of non-plasma water from the drain manifold, Q2 is the flow of plasma water into the drain manifold, and K is the scaling factor. According to the dilution rule, when the plasma water with the pH value of 4 is diluted by 10 times, the plasma water with the pH value of 5 can be obtained; when diluted 100 times, plasma water with a pH of 6 can be obtained. And the plasma water flow of the water discharge branch pipe is regulated according to the proportionality coefficient K, so that the bath water with the required pH value can be obtained conveniently. Alternatively, 1/100.ltoreq.K.ltoreq.1/9. Thus, bath water which is comfortable to the human body can be obtained.
