Abstract
The utility model relates to an electric water heater, which comprises an outer shell, an inner liner, an electric heating pipe, a water inlet pipe, and a water outlet pipe. The utility model is characterized in that the inner side of the inner liner is provided with an air exhaust and water discharge pipe; a fluidic negative pressure device is arranged between the water outlet pipe and a tap water control valve; the fluidic negative pressure device is larger than an inner passage of an interface cavity which is connected with tap water; the inner passage is communicated with a hot water cavity and a negative pressure cavity in the middle part; the negative pressure cavity is larger than an inner diameter of the inner passage; the other end of the negative pressure cavity is a cold and hot water mixing cavity and is connected with a shower pipe. Due to the adoption of an open type structure, the electric water heater belongs to a non-pressure vessel. Therefore, the utility model has the advantages of easy fabrication, good manufacturability, low cost, and high safety. Because the electric water heater is provided with the fluidic negative pressure device, the water supply pressure of the electric water heater depends on the pressure of the tap water, and has nothing to do with the installation of a water heater. The utility model can be used at any height.
Description
The utility model relates to a kind of electric heater, especially a kind of electric heater of vessels not under pressure.
At present, the electric heater of selling on the market mostly is enclosed construction, and its inner bag belongs to pressure vessel, and not only material requires, the manufacturing process complexity, and the cost height, and also use is also very worried, fears the container explosion security incident that contingency causes because of manufacturing defect.
The purpose of this utility model provides a kind of open type electric heater, and not only manufacturing process is simple for it, and cost is lower, and safe and reliable.
The purpose of this utility model is achieved in that it comprises shell, heat-preservation liner, electric heating tube, water inlet pipe and water outlet pipe and control valve thereof, it is characterized in that being provided with in the heat-preservation liner one with the extraneous exhaust outlet pipe that communicates, and between water heater outlet and running water control valve, connect a jet flow negative pressure device that is used for mixing hot and cold water.This jet flow negative pressure device is the three way type structure, it is bigger than the internal diameter of its inner channel with the hub cavity that the running water control valve links, thereby form a jet spray chamber, described passway is hot-water cavity, the negative pressure cavity threeway each other at nozzle and jet flow negative pressure device middle part, but negative pressure cavity than the internal diameter of nozzle more greatly, the other end of negative pressure cavity is the hot and cold water hybrid chamber, and the internal diameter of this hybrid chamber links with bath tube greatly than the internal diameter of negative pressure cavity again.
During use, utilize the pressure of running water, make water in the jet spray chamber, produce high pressure and penetrate from nozzle, because the internal diameter of negative pressure cavity is big than the internal diameter of nozzle, so during jet, produce instantaneous negative pressure at the hot-water cavity place, with the quick sucking-off of the hot water in the hot-water cavity, and in running water flows into hybrid chamber, make hot and cold water be fully mixed to equilibrium, use for shower.
The utility model compared with prior art has following advantage:
1, owing to be provided with in the inner bag and the extraneous exhaust outlet pipe that communicates, the pressure that inner bag bears is zero, belongs to vessels not under pressure, therefore, make simple, good manufacturability, cost is low, safe and reliable, the explosion accident that can avoid pressure vessel to cause because of manufacturing defect fully.
2, when the water supply shower, owing to adopted the jet flow negative pressure device, its pressure of supply water depends on the pressure of running water, is not subjected to the restriction of water heater hanging position, not only can use for arbitrary height, and water temperature control is followed one's bent.
3, this electric heater also can be used as family's cistern and uses when cutting off the water.
4, this electric heater is equipped with upper and lower water level trigger, has superpressure preventing, anti-dry defencive function, and the security performance of use has obtained further perfect.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model jet flow negative pressure device structural representation.
Below in conjunction with drawings and Examples concrete structure of the present utility model is described in further detail.
Referring to Fig. 1,2, the utility model comprises shell, heat-preservation liner 1, electric heating tube 2 and inlet tube and outlet tube 3,5 and control valve 4,6 thereof, relay indicating light is characterized in that being provided with an exhaust outlet pipe 9 that is passed by the bottom in inner bag 1, the upper end of this exhaust outlet pipe 9 is positioned at the top of inner bag, be convenient to exhaust and make overflow pipe and use, between water heater outlet control valve 6 and running water control valve 7, connect a jet flow negative pressure device 8.This jet flow negative pressure device 8 is the three way type structure, it is bigger than the internal diameter of its inner channel 11 with the hub cavity 10 that running water control valve 7 links, passage 11 communicates at the middle part each other with hot-water cavity 12, negative pressure cavity 13, but negative pressure cavity 13 than the internal diameter of passage 11 more greatly, the other end of negative pressure cavity 13 is a hot and cold water hybrid chamber 14, the internal diameter of this hybrid chamber 14 wants big than the internal diameter of negative pressure cavity 13 again, and links with bath tube.In inner bag 1, also be provided with upper and lower water level trigger 15,16, and shell is provided with corresponding indicator lamp and alarm.Use 15 pairs of water inlets of water level trigger water level and detect, when water level reaches trigger 15 positions, produce the signal of telecommunication, indicator lamp is bright, and the prompting user closes cold valves 4; The major function of following water level trigger 16 is: when anhydrous in the inner bag 1 or water level are lower than down the water level trigger but during the misplug power supply, this trigger 16 just sends the signal of telecommunication, makes electric heating tube 2 outages, and alarm, is not burnt out with protection electric heating tube 2.In addition, the upper surface of outlet pipe 5 is higher than the upper surface of water inlet pipe 3, and a little more than the position of electric heating tube 2.
