Description
Technical field
The present invention relates to field of home appliance technology more particularly to a kind of earth detectors for water heater.
Background technique
In real life, people understand has a bath while water heater heating, and this danger close in the process can generate conduction,
Being easy electric leakage danger, it arrives life security, and ground is moist when because having a shower, and electricity returns to ground by personal conduction, so generating electric shock
It is dangerous.Once water heater leaks electricity at this time, it would be possible to cause very big injury to user.Therefore, it is necessary to water heater
Water tank carries out detection of electrical leakage and earth leakage protective.Existing water heater generally solves electrical leakage problems by setting insulation water-trough plate,
It is flowed through in the water stream channel of the upper and lower end face on insulation water plant level ground, Lai Zengchang water flow length, to realize electroshock-proof function.But its
Reliability is not high, and in case of leaking electricity, the protective device only allows human body from the injury of high current.
And electric leakage caused by the reasons such as aging circuit is often slowly to become larger from small, increases the protective device and is leaking electricity
Initial stage user is imperceptible to have electric current using hot water.In this way, cannot also remind user maintenance or replacement as early as possible.Further
Ground, different people are also different to the sensitivity of electric current.To sum up, using the protective device, there are still some potential safety problemss.
Summary of the invention
The present invention provides a kind of earth detector for water heater aiming at defect of the existing technology.
To achieve the above object, the present invention adopts the following technical scheme that, including water route, detection of electrical leakage unit and control
Device；The detection of electrical leakage unit is used to detect the voltage at the water-in and water-out both ends in the water route, and exports the voltage detected；
The controller is connected with detection of electrical leakage unit；The detection unit includes two parts: electric quantity monitoring device and being separately positioned on
The water inlet end in the water route and two probes of water outlet；Two probe is used for when water tank electric leakage, and output is formed in two
The voltage between probe；Controller receives the voltage between two probes, transfinites for judging whether；The electric quantity monitoring device
It is set to water heater metal shell, is sent and is warned to the number of setting by a remote transmission module when detecting dangerous electricity
Show, and live information warning is issued by alarm module.
Further, the controller includes comparator and judging unit；Comparator is for comparing the electricity detected
Pressure and a predetermined voltage, and export comparison result；And judging unit judges whether the water tank leaks electricity according to comparison result.
Further, the mode of information warning is that sound or LED light are shown.
Beneficial effect of the present invention compared with prior art.
The present invention detects the voltage at the water route water-in and water-out both ends by one water route of setting whether to judge the water tank
Electric leakage so as to detect the generation of electric leakage in the case where initial stage user of leaking electricity does not realize also, and further reminds user
Maintenance or replacement eliminate electric leakage hidden danger, improve the reliability of detection of electrical leakage.
The present invention can also monitor electric heater drain conditions in real time by electric quantity monitoring, timely when electricity occurs abnormal
Using a variety of methods issue warn, ensure electric heater using safe.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and detailed description.The scope of the present invention not only limits to
In the statement of the following contents.
Fig. 1 structure of the invention block diagram.
Specific embodiment
As shown in Figure 1, the present invention includes water route, detection of electrical leakage unit and controller；The detection of electrical leakage unit is used for
The voltage at the water-in and water-out both ends in the water route is detected, and exports the voltage detected；The controller and detection of electrical leakage unit
It is connected；The detection unit includes two parts: electric quantity monitoring device and water inlet end and the water outlet for being separately positioned on the water route
Two probes；Two probe is used for when water tank electric leakage, and output is formed in the voltage between two probes；Controller
The voltage between two probes is received, is transfinited for judging whether；The electric quantity monitoring device is set to water heater metal shell, works as inspection
It is sent and is warned to the number of setting by a remote transmission module when measuring dangerous electricity, and scene police is issued by alarm module
Show information.
Further, the controller includes comparator and judging unit；Comparator is for comparing the electricity detected
Pressure and a predetermined voltage, and export comparison result；And judging unit judges whether the water tank leaks electricity according to comparison result.
Further, the mode of information warning is that sound or LED light are shown.
Electric quantity monitoring device, remote transmission module, alarm module use waterproofing design, which can be real-time
Electric heater drain conditions are monitored, warning is issued using a variety of methods in time when electricity occurs abnormal, ensures electric heater
Using safe.
The present invention also passes through one water route of setting, and detects the voltage at the water route water-in and water-out both ends to judge the water tank and be
No electric leakage so as to detect the generation of electric leakage in the case where initial stage user of leaking electricity does not realize also, and is further reminded and is used
Family maintenance or replacement eliminate electric leakage hidden danger, improve the reliability of detection of electrical leakage.
It is understood that being merely to illustrate the present invention above with respect to specific descriptions of the invention and being not limited to this
Technical solution described in inventive embodiments, those skilled in the art should understand that, still the present invention can be carried out
Modification or equivalent replacement, to reach identical technical effect；As long as meet use needs, all protection scope of the present invention it
It is interior.
