Abstract
The utility model discloses a device built-in electric water heater against electric shock, which belongs to the field of household electrical appliances technology. The utility model comprises an admitting pipe and a rising pipe which are made of insulation materials and arranged in an inner liner of an electric water heater, one end of the inner liner is fixedly connected with the admitting pipe and the rising pipe; the admitting pipe takes the shape of bending, a discharge outlet of the admitting pipe is arranged at the bottom of the inner liner of the electric water heater, and a water intake of the rising pipe is arranged at the top of the inner liner of the electric water heater. The utility model has the advantages of smart design, simple structure and safe use; after promoting, the utility model is expected to be warmly welcomed by the masses, as a result, the electric water heater is more competitive in the market.
Description
Technical field
The utility model relates to a kind of safety device of electric heater, and especially the improvement of electric heater anti-electric shock apparatus belongs to household electrical appliance technical field.
Background technology
Along with improving constantly of people's living standard, electric heater has stepped into huge numbers of families, becomes common household electrical appliance.At the existing incomplete actual conditions of house ground connection facility of China, application number is that 00226532.X, name are called " a kind of anti-electric shock apparatus of electric heater " and disclose a kind of insulation aquaporin that cold water is introduced the electric heater main frame and hot water is drawn.Because the two ends of this passage form big resistance, therefore according to the series circuit Ohm's law, even electrical leakage voltage is 220V, also can makes the voltage that acts on human body be lower than safe voltage, thereby guarantee safe in utilization.Yet this class electric shock preventing device structure exposes, and not only influences attractive in appearancely, has also increased the volume and the installing space of electric heater, and it connects complex structure, and heat-insulating property is poor.
Summary of the invention
The purpose of this utility model is: at the deficiency that above prior art exists, proposing does not a kind ofly increase electric heater volume and installing space, simple and compact for structure, good heat insulating, and the better built-in electric heater anti-electric shock apparatus of protection against electric shock effect.
In order to reach the utility model purpose, built-in electric heater anti-electric shock apparatus comprises the inlet tube and outlet tube that insulating materials is made.Wherein inlet tube and outlet tube is arranged in inner container of electric water heater, and an end is fixedlyed connected by reaching the insulation tube joint with the entery and delivery port of electric heater, constitutes airtight insulation aquaporin jointly.Inlet pipeline is circuitous shape, and its delivery port is positioned at the inner container of electric water heater bottom; The water inlet of outlet pipe is positioned at inner container of electric water heater top.
Because inlet tube and outlet tube that insulating materials is made and joint and extraneous pipeline enclosure form the aquaporin of insulation respectively, and the resistance of ordinary tap water and aquaporin radius squared are inversely proportional to, be directly proportional with aquaporin length, therefore as long as the radius and the length of appropriate design aquaporin just are easy to make the resistance at aquaporin two ends to surpass 1M Ω.Like this, at electric heater just in case when making on the inner bag band 220V voltage because of electric leakage, the people (the about 0.2M Ω of the institute of people strip resistance own) of use water heater contacts with the water-in and water-out mouth of pipe and just constitutes a series connection circuit, by the series circuit Ohm's law, the component voltage that add to human body this moment will be lower than safe voltage 36V, thereby avoided the danger of getting an electric shock, guaranteed user's safety.
Compare with existing external anti-electric shock apparatus, the utility model structure is built-in, does not influence original appearance of electric heater and mounting structure at all, so compact conformation, and is easy to implement, good heat insulating.Especially the scientific structure design of pipe connecting piece is reasonable, take into full account and satisfy the requirement of water heater in protection against electric shock and water heater internal structure characteristics, guarantee to remain certain liquid level in the inner bag, can dry combustion method, the particularly circuitous design of inlet tube and outlet tube, effectively prolonged aquaporin, so the protection against electric shock effect is better.
This shows that the utility model design is ingenious, simple in structure, safe in utilization.After estimating to release, will more be subjected to people's welcome, thereby make electric heater have more the market competitiveness.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model embodiment one.
Fig. 2 is the structural representation of the utility model embodiment two.
The specific embodiment
Embodiment one
The built-in electric heater anti-electric shock apparatus of present embodiment is equipped with water inlet pipe 2, outlet pipe 3 and admitting pipe joint 1-1 and titting water outlet 1-2 that ambroin is made as shown in Figure 1 in inner container of electric water heater 1.One end of two pipes fixedly connected with titting water outlet 1-2 with the admitting pipe joint 1-1 of electric heater 1 respectively (insulating with the staving maintenance when pipe joint partly guarantees turnover, water pipe with extraneous the connection) constitutes airtight insulation aquaporin jointly.Water inlet pipe 2 is a compound tube, be nested by interior pipe and outer tube and form, inner water pipeline is circuitous bending, its delivery port is positioned near inner container of electric water heater 1 bottom, during water inlet, cold water by interior pipe from bottom to top, again between the inner and outer pipes from top to bottom, the delivery port from the bottom flows to inner container of electric water heater 1 at last.Outlet pipe 3 is bending, and its water inlet is positioned at inner container of electric water heater 1 top.
Adopt the electric heater of present embodiment structure because water inlet pipe 2 and outlet pipe 3 that ambroin is made are built-in fully, therefore kept the carefully and neatly attractive in appearance of profile.In use, even electrothermal tube 4 leaks electricity, also can be owing to the resistance value at the aquaporin two ends of inlet tube and outlet tube is very big, thus guarantee that the voltage that adds to human body is lower than safe voltage 36V, thus the danger of getting an electric shock avoided, guaranteed user's safety.In addition, the design of the water inlet pipe of present embodiment not only makes cold water reasonably flow into from entering the inner container of electric water heater bottom, and has prolonged aquaporin relatively, increased the resistance value of aquaporin, so the protection against electric shock effect is better.The high position design of present embodiment outlet pipe water inlet then can guarantee to remain in the inner container of electric water heater certain liquid level, can dry combustion method.
Embodiment two
The built-in electric heater anti-electric shock apparatus of present embodiment is gone into shown in Figure 2, and its basic structure and embodiment one are identical.Difference is that water inlet pipe 2 is down " U " shape, like this without outer tube, its delivery port is positioned near inner container of electric water heater 1 bottom.
In addition to the implementation, the utility model can also have other embodiments.For example outlet pipe can be designed to straight tube and be designed to helical form according to the actual conditions of using inner bag, or the like.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the present utility model.
