Abstract
The utility model relates to a full-automatic safety rapid electric water heater which is composed of a box body 1, a box cover 2, a baffle 3 and an electric heating tube 4. The utility model is characterized in that the inner side of the water heater is provided with multilevel security automatic hydrostats, such as a water-controlled power switch 5, a water level switch 6, a pressure switch 7, an explosion-proof drain valve 8, etc. The utility model has the advantages of quick start-up, high heating speed, stable water temperature, the capability of continuous supply for water, convenient operation, small size and high safety.
Description
The utility model relates to a kind of electric heater unit of water, particularly a kind of automatic safety quick electric water heater with multilevel security protective device.
Known electric heater must be opened water intaking valve earlier before use, makes water be full of whole water tank, closes and uses electric switch, makes its energising heating, and its heating process generally needs 15-20 minute, just has the hot water supply to use.Repeat said process behind the hot water in using up case again, and water temperature is difficult to stablize, both time-consuming, trouble again, this type of water heater volume is generally all bigger.
The purpose of this utility model is to adopt water control type power switch, water level switch.Pressure switch and explosion-proof draining valve are realized full-automatic, the safety and the Fast Heating of this water heater, thereby reach simple to operate, and heating is fast, water temperature stability, safe and reliable purpose.
The utility model is to realize in such a way: the automatic safety quick electric water heater of being made up of casing 1, case lid 2, dividing plate 3, electrothermal tube 4, water control type power switch 5, water level switch 6, pressure switch 7, explosion-proof draining valve 8.Running water enters in the water storage cavity 24 from water inlet, enter the water tank water-filling through the water tank water intake hole, when water tank is full of water, the float of water level switch is in the top (Fig. 2) in the water tank, and be in a horizontal position with the outer magnetron 15 of water tank, the powerful magnetic line of force in the float is two contact adhesives of magnetron, and the circuit that makes magnetron connect electrothermal tube is outward connected.Running water continues to enter water storage cavity, because the diameter of inlet opening is greater than the diameter of apopore (being the water tank water intake hole), so the static pressure in the water storage cavity progressively increases, force the rubber membrane 9 in the water control type power switch outwards to be heaved, driving holder 10 promotion moving contacts 11 engages with static contact 12, circuit is connected, thereby electrothermal tube is heated.When closing inlet valve or cutting off the water supply, the static pressure in the water storage cavity disappears, and power supply just cuts off automatically.Water level switch sank and outage automatically when the anhydrous or water level that arrives for some reason descended when water tank, thereby prevented dry combustion method, prevented the electrothermal tube dry combustion method and impaired.Device communicates with the waterway of water tank in the bottom of the pressure switch 7 (Fig. 3) on water tank top, water heater is when normal operating condition, micro power switch in the pressure switch is in channel status, but when water route or delivery port obstruction, the interior water temperature of case raises rapidly and reaches boiling point, uprushing of steam pressure upwards heaved the rubber film in the pressure switch, thereby the moving contact 18 that promotes micro power switch breaks away from contact 19, circuitry cuts.The circuit of above-mentioned three switches all adopts series circuit, as long as in the water heater break down in a certain position, all can cut off entire circuit rapidly, thereby effectively protect water heater, prevents the generation of accident.Be installed in the explosion-proof draining valve 8 (Fig. 4) of water tank bottom, when the normal hydraulic pressure of water heater, its osculum is in closed state, and when occurring the too high or steam pressure of hydraulic pressure in the water tank and rise, its pressure forces the spring 23 in the explosion-proof draining valve to be compressed, drive the interior sealing rubber plug 22 of valve to bottom offset, water in the water tank or steam prevent the water tank blast just from the osculum ejection.
Below in conjunction with accompanying drawing enforcement of the present utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model water level switch;
Fig. 3 is the structural representation of the utility model pressure switch;
Fig. 4 is the structural representation of the explosion-proof draining valve of the utility model.
As shown in Figure 1, by the automatic safety quick electric water heater that casing 1, case lid 2, dividing plate 3, electrothermal tube 4 are formed, it is characterized in that a water control type power switch 5, water level switch 6, pressure switch 7 and explosion-proof draining valve 8 being housed at this water heater.A temperature resistant rubber film 9 is arranged in the water control type power switch, connect a holder 10 on the rubber membrane, also have a moving contact 11 and static contact 12 and spring 15 in the water control type power switch.Water level switch 6 (Fig. 2) is made up of float 14 and magnetron 15, and a powerful permanent magnet 16 is arranged in the float.Have in the pressure switch 7 (Fig. 3) a temperature resistant rubber film 17 and water every, a micro power switch of being made up of moving contact 18 and contact 19, spring 20 is housed in the pressure switch.A hollow holder 21 is arranged at explosion-proof draining valve (Fig. 4) top, and a sealing rubber plug 22 and spring 23 are arranged in the explosion-proof draining valve.
The utility model is provided with the multilevel security automatic explosion-proof device, has starting rapidly, Firing rate is fast, water temperature stability, but continuous water supply, and easy and simple to handle, volume is little, peace Complete reliable characteristics.
