Description
Technical field
The invention belongs to storage-type electric water heater field.
Background technology
At present, the power supply of electric heater all uses alternating current 220V 50Hz, by I appliances design, wherein
I class: have operational insulation, has ground termination points and earth connection, it is stipulated that must ground connection or connecting to neutral.Earth connection is necessary
Use appearance is the copper conductor that yellow green is double-colored, and contact resistance should be little 0.1 ohm.And this electric heater
The reason causing electric shock accidents generally has three aspects: first aspect comes from water heater itself, water-heater water tank
The use that interior electrothermal tube is long-term causes the corrosion adding heat pipe metal surface, will break when arriving its limit
Split, cause heating wire and water to be connected, the voltage of 220V directly by current and flow through human body and form path over the ground,
Substantial amounts of electric current is made to pass through human body；The permanent of heart is will result in when the electric current more than 50mA flows through heart
Property destroy, the most dead.Second aspect is that (earth resistance is larger than standard when earthed system exception
Regulation), particularly earthed system lost efficacy (the most obstructed or there is no ground wire with the earth) time, it reforms into 0 class formation
Electric heater, and the protection against electric shock environment to be depended on of 0 class electric heater, and such electric heater is typically
It is placed in bathroom use, it is impossible to provide protection against electric shock with environment.The third aspect is that ground wire itself is charged,
Water heater itself mostly has good earth connection, and the eliminating of its leak current fault just relies on good ground connection, but
When ground wire is the most charged, water heater is instead tired out by it, draws when causing librarian use water heater equally or touch water heater
Rise and get an electric shock.
Above-mentioned all accidents occur repeatedly for many years, too numerous to enumerate.And the leakproof that current electric heater is the most frequently used
(when leakage current is more than 10mA, electric heater can be at 0.1s the most all to use earth leakage protective device
Inside automatically cut off power supply, it is ensured that the life safety of user)；But when earth leakage protective device is malfunctioning or damages, use
Family is currently in use hot water, just has a big electric current (the most high-power water heater) through human body, occurs to cause people dead
The accident died.
It addition, the water feed apparatus of current electric heater (especially horizontal hanging type installation electric heater), often there are three kinds
By structure: 1. U-shaped path formula water feed apparatus, 2. lead directly to the board-like water feed apparatus of dash, the 3. many side openings of cylindrical circumference
Formula water feed apparatus.But, the first 1. structure complicated, pipeline is oversize, and Long-Time Service water route easily blocks；The
2. two kinds to be welded a water fender on inner-tube structure, higher to welding process requirement, easily produces welding and lacks
Fall into, make inner bag leak；The third 3. its simple in construction, but go out water speed quickly when water inlet, easily cause disorderly
Stream, the cold water made into carries out unordered mixing with the hot water in inner bag, causes output hot water water temperature unstable (suddenly
Cold heat suddenly), the hot water delivery rate of electric heater will be substantially reduced.
In order to solve these problems above-mentioned, present applicant has proposed the electric heater design structure of a kind of novelty；Tool
Body employing measure is:
The applicant proposes the water-in and water-out device of assembly insulation system；Water resistance is utilized to limit leakage current big
Little " charged water resistance method ", makes the leakage current in water inlet front end be less than 2.5mA, thus ensures user
Life safety.The human body accessible metal parts such as the exposed urceolus of electric heater are designed with II simultaneously
The structure of appliances.
It addition, be provided with the parts such as insulation taper water knockout drum in assembly insulation system water feed apparatus, it is possible to
Change the flow direction into water fluid, increase the resistance of fluid flowing, reduce the speed that fluid flows out；Ensure
Fluid is laminar state flowing in inner bag, it is to avoid the turbulent phenomenon in inner bag, it is ensured that in inner bag, water temperature is steady
Qualitative and improve the hot water delivery rate of electric heater.
Summary of the invention
For the deficiencies in the prior art, the invention reside in proposition one and prevent human electric shock's injures and deaths and have high hot defeated
Going out the electric heater of power, this electric heater belongs to electrical equipment II class safety standard, uses double insulation, does not connect
Ground requirement, improves safe coefficient, can be used for directly contacting with human body skin；And by water resistance limit into
The leakage current at the mouth of a river is less than 2.5mA, it is ensured that the life security of user；It addition, water feed apparatus is to pass through
Various insulation structure combinations form, and change the flow direction into water fluid, increase the resistance of fluid flowing,
Reduce the speed of fluid flowing so that fluid is laminar state in inner bag, improve stablizing of water temperature in inner bag
