Description
Technical field
The utility model is related to household electrical appliance electric leakage protection technology field, more particularly to a kind of household electrical appliance
The device of the pole of power supply circuits three can be disconnected while power-off.
Background technology
All the time in use, often there is unexpected electric shock injury accident in Jing with I classes household electrical appliance,
And cause the main cause of these accidents to be not because caused by the electric leakage of product itself, and being because in electrical network
Ground wire electrification (or L, N line is anti-phase) connection, then by product ground wire (or powered N lines) fax
To on the body of people, so as to electric shock accidents occur.
Occur such case, mainly user for inherently safe and convenience, in household electrical appliance (such as
The solar water heater of electric heater, the Teat pump boiler of electrified heating or electrified heating) enter at electricity generally
L, N the two poles of the earth or single-pole switch are only installed, this installation operation mode of user can cause two subject matters：
1) user concurrently or separately disconnects L, N the two poles of the earth of household electrical appliance by combined socket and switch, and ground wire is not
Disconnect, although household electrical appliance are not charged, but also result in the plug of household electrical appliance and lose ground wire because not charged
Electrization protection function.Such as：The pole leakage protecting plug of electric heater three, after upper electricity, three pole leakage protecting plugs
If detecting ground wire electrification, will oneself tripping operation power-off protection.But this function is only limitted to three pole earth leakage protectives
Plug could work when having electricity, if without electricity, it just loses earth wire charged protecting function.

Two-stage switchs 02 and supplies electricity to disconnected, and leakage protecting plug 01 just cannot work because of dead electricity, now electric heater
03 ground wire is still connected with the ground wire in electrical network.Now, if the household electrical appliance 05 of certain shared ground wire leak electricity,
So that the ground wire electrification in electrical network, because ground wire is not turned off so that the fuselage of electric heater 03 is powered, user takes a shower
When touching electric heater 03 just have shock hazard.
2) because part domestic electric network installs lack of standardization, cause on the socket for domestic electric appliances of man of certain customers
The single-way switch that L extremely goes up that should be mounted in be mounted in N poles, household electrical appliance, will L, N when this socket is powered
Line is anti-phase.If user is accustomed to disconnecting single-pole switch 04 when using electric heater 03, because L, N line is anti-phase, break
Electricity is also only disconnected the N poles of electric heater 03.Now L poles of electric heater or powered, if user is because
Disconnect single-pole switch 04 and remove to touch electric heater, just have shock hazard, as shown in Figure 2.
Frequently occur electric shock accidents in household electric appliances to occur mainly in bathroom, this is because people is in bathing
During, whole body all gets wet and directly contact with ground.When a water heater fuselage is powered, people will exist tactile
It is electric dangerous.At present, the measure do not got an electric shock between water heater and people for point in industry mainly has：
1) anti-electricity wall is increased in water heater intake-outlet；Structure is relative complex, nor can be from basic
On prevent electrical leakage problems.
2) using three poles disconnect leakage protecting plug, but the plug must have energization in the case of just can rise
Protective effect, when combined socket and switch deenergization is passed through before plug, leakage protecting plug is because no power works
Protective effect is not had.
