Embodiment
For make present invention solves the technical problem that, the technical solution that uses and the technique effect that reaches it is clearer, below
The technical solution of the embodiment of the present invention will be described in further detail with reference to attached drawing, it is clear that described embodiment is only
It is part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those skilled in the art exist
All other embodiments obtained under the premise of creative work are not made, belong to the scope of protection of the invention.
Present embodiment provides a kind of leakage detection method for water heater, and this method is to be examined respectively using water flow sensor
Survey the water flow of water tank inlet and water outlet；The difference in flow of water inlet and water outlet is calculated, difference in flow is pre- with controller
If threshold value A compare；If difference in flow is more than threshold value A, controller controls the solenoid valve on water inlet pipe to close, while alarm report
It is alert.This method can be used in the equipment such as gas heater, solar water heater, electric heater, it is preferable that present embodiment is with this
Method illustrates exemplified by the application in gas heater.
As shown in Figure 1, the gas heater that present embodiment provides includes shell 1 and the water tank 2 in shell 1,
One end of the water tank 2 is connected with cold water inlet 21, and the other end is connected with hot water outlet pipe 22, wherein water inlet pipe 21 and outlet pipe
One water flow sensor 3 is respectively installed on 22, is respectively used to the inflow of detection water inlet pipe 21 and the water yield of outlet pipe 22.
When water heater just common water, its inflow is substantially equal to water yield；And when bursting by freezing seepy question occurs for water heater, its water outlet
The mouth typically no current of b, and the water flow sensor 3 at water inlet a can then detect numerical value, when the difference in flow of entery and delivery port
During more than certain threshold value A, you can judge that leak has occurred for the water tank 2 of the water heater.
Further, solenoid valve 4 is also equipped with water inlet pipe 21, controller 5 and alarm 6 are installed on shell 1.Such as figure
Shown in 2, controller 5 is electrically connected with above-mentioned two water flow sensor 3, solenoid valve 4 and alarm 6 respectively, wherein two water flows
Sensor 3 will detect signal and be sent to controller 5, and the comparison module and computing module in controller 5 carry out two detected values
Compare calculating, obtain entery and delivery port difference in flow, then by the difference in flow compared with threshold value A, when difference in flow is more than threshold value A
When, the control module in controller 5, which sends instruction, closes inlet valve 4, cut-out water inlet, while alarm 6 is opened alarm.
Further, since the smoke exhaust pipe of gas heater is communicated with outside atmosphere, to prevent the winter temperature of cold from holding
Continuous reduction causes 2 bursting by freezing of water tank, and electric heating body is additionally provided with present embodiment water tank 2, warming anti-for being carried out to water tank 2
Shield.Meanwhile temperature sensor 7 is provided with outside water tank 2, for detecting the temperature of water tank 2, facilitate user according to temperature change and
When take measures, prevent 2 bursting by freezing of water tank.Preferably, display panel is additionally provided with shell 1, being capable of each water flow biography of real-time display
The detected value of sensor 3 and temperature sensor 7, is observed easy to user.
Specifically, as shown in figure 3, the leakage detection method for water heater that present embodiment provides comprises the following steps：
S1：Water heater is powered；
It should be noted that the water upper first of controller 5 is pressed first in use, user is first opened with water spot after installation
Key, solenoid valve 4 are opened, and when with water spot outflow water (water tank full water), user is closed with water spot, and controller 5 is switched to just
Normal use state.In above process, solenoid valve 4 is always on, from the influence of water flow sensor 3.
S2：Set the threshold value A of water heater leak water detdction；
During normal use, entering water electromagnetic valve 4 is in normally open, here due to the difference in operation and systematic error of user
In the presence of the flow value at water inlet a and water outlet b has little bit different, in order to reduce the influence that the difference judges leak, keeps away
Exempt from erroneous judgement and cause alarm equipment alarm, this detection method is provided with threshold value A.The threshold value A can be carried out according to the size of water-heater water tank 2
Setting, it is preferable that the capacity of water tank 2 is 8-10L in this example, and threshold value A is set as 0.5L or 1L.
S3：Detect the water flow at water tank inlet a and water outlet b respectively using water flow sensor 3；
In the present invention, water flow sensor 3 is preferably Hall flow meter, it is mainly by copper valve body, water flow rotor component, steady
Component and Hall element composition are flowed, wherein Hall element can measure water frequency signal, and frequency is bigger, then water flow is bigger.
S4：Compare the size of current detection values at the above two, calculate the difference in flow of water inlet a and water outlet b；
S5：Compare the size of difference in flow and threshold value A, if difference in flow ＞ threshold value As, controller 5 is controlled on water inlet pipe 21
Solenoid valve 4 is closed, while alarm 6 starts to alarm, if difference in flow≤threshold value A, return to step S3 continues to detect.
In this step, alarm 6 is preferably audible-visual annunciator, including buzzer and indicator light, by buzzer rings and
User's timely processing seepy question is preferably reminded in indicator light flicker.In addition, controller 5 is preferably microcontroller, microcontroller receives
The pulse signal that two water flow sensors 3 are sent, after discriminatory analysis, controls solenoid valve 4 and alarm 6 to act.
The application installs water flow sensor 3 on the water inlet pipe 21 and outlet pipe 22 of water-heater water tank 2 respectively, passes through ratio
Compared with entery and delivery port difference in flow and the size of threshold value A, to judge whether water tank 2 occurs leak, if confirming leak, close in time
Entering water electromagnetic valve 4, prevents more tap water from entering water tank 2 and causes a large amount of water to reveal, so as to thoroughly avoid water heater
The problem of leak is more than.Meanwhile the present invention makes testing result more accurate by given threshold A, control is more reliable, avoid by
In user's operation is improper or systematic error and caused by error in judgement, improve machine operation efficiency, ensure that user uses peace
Entirely, the economic loss caused by seepy question is reduced.
Note that it above are only presently preferred embodiments of the present invention and institute's application technology principle.It will be appreciated by those skilled in the art that
The invention is not restricted to specific embodiment described here, can carry out for a person skilled in the art various obvious changes,
Readjust and substitute without departing from protection scope of the present invention.Therefore, although being carried out by above example to the present invention
It is described in further detail, but the present invention is not limited only to above example, without departing from the inventive concept, also
