Abstract
A safe-use protective device for a water storage type water heater is used for preventing casualties caused by leakage of electricity while the water storage type water heater is used. The safe-use protective device for the water storage type water heater is composed of a water flow sensor, an alternating current (AC) and direct current (DC) power converter, a two-pole two-way controller, a state indicating lamp and a power line. When a user starts showering, the water flow sensor is connected with a control circuit, and at the moment, the water heater is in the state of not heating. Meanwhile, the state indicating lamp on a panel is lightened to inform that the circuit is already disconnected. So long as the user is taking a shower with water, the circuit is always in the state of disconnection. When the user stops showering and shuts down water flows, the water flow sensor is reset, the AC and DC power converter does not control voltage output, and simultaneously the state indicating lamp goes out. The two-pole two-way controller works, the power supply is connected, and the heating function is restored so that the safe protective function of disconnection on water use and connection on water shut is achieved.
Description
Technical field
The utility model relates to the safe handling protective device of storage-type electric water heater.Specifically, prevent a kind of safety guard of causing casualties after storage-type electric water heater in use leaks electricity exactly.
Background technology
The storage-type electric water heater that uses at present mainly adopts following two kinds of anticreep methods, and first power line adds earth leakage protective device.It two is Fang Dianqiang that delivery port installs water resistance additional.But the phenomenon that water heater does not connect earth connection (having a lot of areas at all just not have earthing or grounding means) in the actual installation use often takes place, if water heater liner or shell are charged, earth leakage protective device is not worked, and devices such as anti-electric wall also lose protective action.There is a kind of potential potential safety hazard all the time in storage-type electric water heater like this.
Summary of the invention
It is a kind of when storage-type electric water heater is brought into use that the utility model provides, and two end power supplys of electrical heating elements cut off the power supply automatically, makes water heater not have the root of any electric leakage, and after stopping using, the automatic energized of circuit, heater is started working.This device can be installed on the using appliance of various storage-type electric water heaters.
The task that the utility model proposes realizes through following method: storage-type electric water heater safe handling protective device, its general structure is made up of current inductor, AC-DC converter, bipolar reversible controller, green indicating lamp, power line.The current inductor is installed in the water inlet of storage-type electric water heater, and status indicator lamp is installed on the water heater panel, and AC-DC converter, bipolar reversible controller are installed in the shell of water heater.After the water heater energized, heater begins the work of heating automatically.When the user begins shower; The current inductor is connected control circuit; The two-way bipolar controller of control voltage starting of AC/DC changeover switch output, heater two end power supplys are broken off in two-way bipolar controller work, and this moment, water heater was in not heated condition; The panel status indicator lamp is lighted simultaneously, informs that circuit breaks off.As long as the user is in the water shower, circuit just is in off-position always.Shower stops, and closes current, and the current inductor resets, and AC-DC converter does not have the output of control voltage, and status indicator lamp extinguishes simultaneously, and two-way bipolar controller work energized is recovered heating function.Reached the water outage, the safety protection function of Guan Shui energising.
Description of drawings
Below the accompanying drawing and the enforcement of the utility model is described further.
Accompanying drawing is the electrical equipment control schematic diagram of safe handling protective device.
1. power line in the accompanying drawing, 2. AC-DC converter, 3. current inductor, 4. two-way bipolar controller, 5. status indicator lamp, 6. heater
The specific embodiment
The utility model is installed in the storage-type electric water heater.3. current inductor in the safety device is installed in the water inlet of storage-type electric water heater; 5. status indicator lamp is installed on the housing face-plate; AC-DC converter is fixedly mounted in the shell of storage-type electric water heater after 2. 4. being assembled on the insulating sheet material with two-way bipolar controller again, and 6. two-way bipolar controller output 4. is connected with heater through lead.2. the assembling AC-DC converter will keep a determining deviation with two-way bipolar controller insulating sheet material 4. with contiguous metallic conduction object in fixation procedure, make the power supply of input not have any contact with the inside and outside housing of water heater, to guarantee safety.The energized line 1. the back as current through the current inductor 3. the time; To AC-DC converter 2. 3. the current inductor just produce a signal; This moment AC-DC converter 2. produce a control voltage make the two ends output 4. of two-way bipolar controller and heater 6. two ends be connected disconnection, 5. the while status indicator lamp is lighted.At this moment water heater is in no electric protection state.Shower finishes to close the water source, the current inductor 3. send signal through AC-DC converter 2. make the two ends output 4. of two-way bipolar controller and heater 6. two ends be connected, recovery is to the heating work of store water.
The equipment that the utility model also can be used for various storage-type electric energy heating liquids and heating back liquid flow is used.
Claims (1)
1. the safe handling protective device of a storage-type electric water heater; Be installed in the work loop of storage-type electric water heater, it is characterized in that controlling the work of AC-DC converter and two-way bipolar controller disconnection or connection heater after shower begins or finishes by the signal of telecommunication that the current inductor that is connected the storage-type electric water heater water inlet sends.
