In order to realize the control that heating tube 10 is heated, described anti-electric shock type electric water heater also comprises the operation control panel 11 being connected with power board 12, and operation control panel 11 is transported to the working power of heating tube 10 for controlling power board 12.
Better electrically transmit barriering effect in order to reach between water inlet pipe 5 and outlet pipe 6, the total length of water inlet pipe 5 should be greater than 53r
1 2(r
1for pore radius in water inlet pipe), the total length of outlet pipe 6 should be greater than 53r
2 2(r
2for pore radius in outlet pipe).
Further, in order to improve the isolated effect of overall current between inner bag 3 and user, the outside water inlet pipe (not shown) of inner bag 3 and outlet pipe (not shown) also adopt insulation tube.
Further; form incrustation scale in order to prevent that inner bag 3 is corroded and avoids in water impurity to be attached in inner bag 3; described anti-electric shock type electric water heater also comprises the sewage draining exit 7 of being located in inner bag 3; and be fixed at the magnesium rod 4 on sewage draining exit 7; this magnesium rod 4 is for carrying out anti-corrosion protection to inner bag 3, and this sewage draining exit 7 is for the sewage of emptying inner bag 3.
Further, described anti-electric shock type electric water heater also comprises the safety valve 9 of being located on the outside water inlet pipe of inner bag 3, be used for ensureing mediating in time pressure in the time that heating process hydraulic pressure is excessive, ensure to use safety, so generally in heating process, safety valve 9 has water droplet out, but safety valve 9 is bound to drip neither say heating time, if hydraulic pressure just can not drip in safety valve 9 tolerance ranges; And prevent aqueous reflux when stopping into water at inner bag 3, ensure inner bag 3 interior must be the state of full water, avoid dry combustion method.
Further, described anti-electric shock type electric water heater also comprises the tee pipe coupling 8 of being located on the outside outlet pipe of inner bag 3, be used for making described anti-electric shock type electric water heater to there are two hot water effluent's pipelines, avoid single hot water effluent's pipeline to bring single hot water supply water exit position.
Further, water inlet pipe 5 comprises inner and outer tubes (not shown), and the top of inner tube is provided with the apopore being communicated with outer tube, and outer tube offers some apopores along outer tube circumferential distribution near the lower fragment position of inner bag 3 bottoms.In the process of electric heater work, cold water flows in inner bag 3 successively after the apopore of the gap between apopore, the inner and outer tubes of the inner tube of water inlet pipe 5, inner tube and outer tube, because the apopore diameter of the upper setting of water inlet pipe 5 is conventionally less, in the situation that occurring compared with flood flow, the flow velocity of water can be very large, thereby the water body in inner bag 3 is caused to larger disturbance, accelerate the mixing velocity of hot and cold water, destroy the hot and cold water layering in inner bag 3, can not effectively the hot water on upper strata be discharged by outlet pipe 6, reduce hot water delivery rate.In order to slow down the cold water flowing to inner bag 3 from water inlet pipe 5, the water body in inner bag 3 is caused to larger disturbance, avoid the hot and cold water layering in inner bag 3 to be destroyed, thereby ensure that described anti-electric shock type electric water heater has higher hot water delivery rate, described in this, the water inlet pipe 5 of anti-electric shock type electric water heater is also set with water inlet kuppe 20(that the apopore of offering on water inlet pipe 5 is covered as shown in Figure 2), the shape of water inlet kuppe 20 can be cylinder, side's body or other arbitrary shape bodies, this water inlet kuppe 20 is provided with exhalant canal, carry out water conservancy diversion with the cold water that the apopore from outer tube is flowed out, make sluggish flow, flow to equably in inner bag 3.Water inlet kuppe 20 comprises kuppe body 21 and is convexly set in the retaining section 22 on this kuppe body 21, on kuppe body 21, offer the first through hole 211 passing for water inlet pipe 5, thereby realize, water inlet kuppe 20 is directly sleeved on water inlet pipe 5, simple in structure, it is convenient to install.The retaining section 22 arranging on kuppe body 21 can be realized the cold water that the apopore from water inlet pipe 5 is flowed out fast and be stopped layer by layer, reduce the kinetic energy of cold water, and cold water mobile between retaining section 22 easily forms turbulent flow, therefore greatly reduced the flow velocity of water inlet, solve existing electric heater in use destroys hot and cold water layering problem because injecting cold water, improved hot water delivery rate and the energy consumption that has reduced electric heater.
Further, in the present embodiment, on kuppe body 21, convex with at least two-layer spaced apart retaining section 22, retaining section 22 offers multiple delivery ports 221, the delivery port 221 arranging on every layer of retaining section 22 is roughly along the peripheral distribution of water inlet pipe 5, thereby expand the scope that current distribute, make the water flowing out from water inlet pipe 5 inject more equably inner bag 3, and having at least the delivery port 221 arranging on two adjacent two-layer retaining sections 22 to be is in staggered distribution, gap and delivery port 221 between each layer of retaining section 22 form aquaporin, the current that this exhalant canal can make to flow through wherein produce turbulent flow, thereby reduce flow rate of water flow.The exhalant canal that arranges on kuppe 20 of simultaneously intaking also increased the area of passage of cold water, further reduced cold water and enter the flow velocity of inner bag.Therefore, the impact of cold water to hot water layer can be alleviated or avoid to the water inlet kuppe 20 of the present embodiment, improved the hot water delivery rate of electric heater and saved electric energy.
Should be understood that; these are only preferred embodiment of the present utility model; can not therefore limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
