Problems solved by technology

[0003] Since the current transformer needs to realize the current induction conversion from the primary side to the secondary side through the coil, the structure is limited to a ring shape, and it needs to be placed on a line or pipeline before it can be used, which limits its use environment. In addition, the current mutual inductance detection scheme is due to The detection is the current, which needs to rely on the inductance coil, the cost is high, and there is no advantage in cost control

Embodiment 1

[0037] See Figure 1 to Figure 3 , the shell 1 of the electric water heater is provided with a water storage tank 8, the heat pipe 7 is placed horizontally on the water storage tank 8, and the bottom of the shell 1 has a water inlet 3, a water outlet 4, and a sewage discharge interface 9 respectively connected to the water storage tank 8 through pipelines, wherein, The sewage interface 9 is detachably installed with a sewage interface plug 10 for sealing the sewage interface 9 when no sewage is required.

[0038] Among the above, the junctions of the water inlet 3, the water outlet 4, the sewage outlet 9 and the shell are all provided with interface decoration covers. See Figure 4 , the decorative cover at the water inlet 3 is divided into two parts, one part is the base 12, the other part is the cover body 13, the base 12 is an annular slot with a depression in the middle, the inner ring opening of the annular slot is adapted to the water inlet 3, and the outer The ring sn...

Embodiment 2

[0070] Embodiment 2 On the basis of Embodiment 1, a power carrier module is added on the electric water heater, and the power carrier module communicates with the controller 2. When a leakage signal greater than 12V is detected, the voltage sensing alarm device 5 sends an alarm signal to the To the controller 2, trigger the controller 2 to control the power board 11 to cut off the main power supply of the electric water heater, voice prompts, and at the same time, the controller 2 transmits the power carrier signal to the external power carrier controller through the power carrier module through the phase wire, and the external power carrier controller It can be interconnected with other smart home devices, and it will send out a warning after receiving the power carrier signal.

[0071] The user immediately evacuates from the dangerous area according to the signal prompted, and asks professionals to carry out maintenance to reduce accidents.

Embodiment 3

[0073] Embodiment 3 On the basis of Embodiment 1 or 2, a network connection communication module electrically connected to the controller 2 is added on the electric water heater, such as a Bluetooth module, a WIFI module, etc., and the network connection communication module is connected to a router or a mobile phone or a tablet computer. Communication, when a leakage signal greater than 12V is detected, the voltage sensing alarm device 5 sends an alarm signal to the controller 2, triggers the controller 2 to control the power board 11 to cut off the main power of the electric water heater, voice prompts, and the controller 2 passes The network communication module sends a wireless alarm signal to the Internet platform, manufacturer platform, and power bureau. After receiving the signal, the Internet platform, manufacturer platform, and power bureau notify the user to evacuate from the dangerous area.

Abstract

The invention provides a voltage induction type alarm device and an alarm method thereof. The device comprises a probe, a voltage amplifier, a control unit and a warning device; the probe is used forsensing the electric field intensity of leakage voltage; one end of the probe is connected to the input end of the control unit through the voltage amplifier; the control unit triggers the warning device to give a warning according to the output voltage of the voltage amplifier. According to the voltage induction type alarm device, voltage induction type detection is adopted, so that no physical contact is not needed. The voltage induction type alarm device is simple in structure and adopts few components. Compared with a current mutual inductance detection scheme, the voltage induction type alarm device can greatly reduce the cost; and the voltage induction type alarm device is provided with the warning device, and therefore, in extreme cases, such as an external controller is abnormal due to electric leakage, the voltage induction alarm device can still give an alarm to remind a user to evacuate from a dangerous area immediately.

Description

technical field [0001] The invention relates to the field of electric leakage detection, in particular to a voltage induction alarm device and an alarm method thereof. Background technique [0002] Existing leakage detection often relies on the implementation of current transformers. When in use, the current transformers are set on the lines or pipelines, and use the principle of electromagnetic induction to detect whether there is current flowing. When the current flows, a signal is sent to the controller. The controller implements corresponding protective measures. [0003] Since the current transformer needs to realize the current induction conversion from the primary side to the secondary side through the coil, the structure is limited to a ring, and it needs to be placed on the line or pipeline before it can be used, which limits its use environment. In addition, the current mutual inductance detection scheme is due to The detection is the current, which needs to be re...
