Abstract
The utility model relates to a water-flow controlled electronic switch, the electronic switch is controlled by using water-flow for the device, particularly the electronic switch used for an electric water heater. The switch is composed of a switch housing body, an electromagnetic coil and a magnetic float. The electromagnetic coil is positioned on a coil frame out of the switch housing body, the magnetic float is positioned in a float chamber in the switch housing body, a water inlet of the switch is arranged at the lower part of the switch housing body, a water outlet is arranged at the upper part of the switch housing body, the float chamber is arranged between the water inlet and the water outlet, and the height of the float chamber is more than two times for the height of the magnetic float. When water-flow passes through the switch housing body, the magnetic float floats upwards, and a switch signal is generated by a triggering electromagnetic coil.
Description
The utility model is a kind of device that utilizes current that electronic switch is controlled, and especially is applied in the electronic switch on the electric heater.
Heating power supply switch in the electric heater generally is to compress switch by mechanical water to control, the control mode of water yield has preposition control and postposition to control two kinds, preposition control is the water inlet that water valve is contained in water heater, and when closing, the water heater pressure inside is an atmospheric pressure; Rearmounted control is the delivery port that water valve is contained in electric heater, when closing, the water heater pressure inside is a pressure of supply water, therefore to compress switch generally be to install under valve is made the situation of preposition control to mechanical water, makes on-off action by the mechanical water switch that promotes heating power supply that compresses switch, when delivery port takes place to stop up or other reason causes the delivery port water outlet at need, because hydraulic pressure switch is failure to actuate, heating power supply will continue heating always, up to damage, sometimes even can blast.Therefore present electric heater exists unsafe hidden danger always.
Goal of the invention of the present utility model just provides a kind of electronic switch that can guarantee in the current control that does not have to close automatically under the situation of current the electric heating switch.
The electronic switch of current control of the present utility model is made up of switch case, solenoid, magnetic float, and solenoid is positioned on the bobbin in the switch case outside, and magnetic float is positioned at the float chamber of switch case.The bottom of switch case is a water inlet, and top is delivery port, and float chamber is positioned in the middle of the switch case, and promptly between water inlet and the delivery port, bobbin is positioned at the first half in the float chamber outside.The height of float chamber is greater than 2 times of the magnetic float height.The circumference of magnetic float is provided with tank.When current passed through this switch, having floated the magnetic float in the seed cell will be floated in the flowing water picking-up in the middle of the solenoid, thereby makes solenoid produce a current signal, is triggered the mains switch of heater by this current signal.When not having water to flow through this switch, magnetic float will fall, and drops down onto outside the solenoid, and this moment, solenoid just lost current signal, so electric heater will cut out automatically.
Adopt the electronic switch of current control of the present utility model, its advantage is:
When 1, no matter breaking down even not having current to flow through heating part at any position of electric heater, this switch will be cut off the electricity supply immediately, prevents the dry combustion method phenomenon of electric heater effectively, and the protection water heater is not burnt out.
2, when delivery port took place to stop up, this switch also can cut out heating power supply immediately, stopped heating, prevented that heater from continuing to avoid taking place the accident of thermal explosion to resting on the water heating in the heating inner bag.
3, practical, when the hydraulic pressure deficiency, but when current were arranged, general hydraulic pressure switch just can not opened, therefore just heating power supply can not opened yet, tend to cause there are flowing out, but do not have heated phenomenon, and the utility model just this problem can not occur, as long as current are arranged, hydraulic pressure size no matter, electric heating system will operate as normal, the phenomenon of cold water therefore can not occur flowing out from electric heater.
4, simple in structure, cost is low, easy to use, reliability is high.Can be applicable to various electric heaters.
Fig. 1 is a structural representation of the present utility model.Switch case 1, water inlet 1-1, delivery port 1-2, float chamber 1-3, bobbin 1-4, solenoid 2, magnetic float 3 are wherein arranged.
Fig. 2 is the vertical view of magnetic float, comprising tank 3-1
Its embodiment of electronic switch of current control of the present utility model is: switch case 1 adopts the non-magnetic material, as the engineering plastics single injection-molded, the centre of this switch case is a tubulose, from water inlet 1-1 by float chamber 1-3 until delivery port 1-2 is hollow cylindrical, on the periphery of switch case, be provided with a bobbin 1-4, this bobbin is an one with switch case also, and is positioned at the first half of switch case, and solenoid 2 places in the bobbin.Magnetic float 3 is arranged in the float chamber of switch case, magnetic float can be column and also can be spherical, in order to guarantee that the magnetic float come-up time do not block delivery port, therefore on the excircle of magnetic float, be provided with a few road tank 3-1, the external diameter of magnetic float is less than the internal diameter of float chamber.The electromagnetic wire encircled energy produces current signal in order to ensure in float rises to solenoid the time, and magnetic float can in time be eliminated current signal when falling reposition, therefore, the height of float chamber is greater than the height of 2 times magnetic float, just in time in the central authorities of solenoid, and the Hui Shineng that falls breaks away from solenoid fully when guaranteeing that magnetic float floats.Magnetic float adopts magnetic to sneak into injection molded of plastics, guarantees that its proportion is slightly larger than the proportion of water.Make when current, just magnetic float to be held up, when not having current, the magnetic float reposition that can fall automatically.According to the above, just can be made into the utility model.
