Abstract
The utility model relates to a fuse structure of an electric faucet, which utilizes a piece of hot-melting metal to be connected with two separated terminals in a circuit so as to enable the two terminals to be electrically connected to connect the circuit. When current is overloaded and the circuit is overheated, the hot-melting metal is fractured to enable the circuit to be in an open circuit state. The fuse structure can be used as a protective device for safe use of the electric faucet specifically. When the current passes through the electric faucet is too high, or a heating tube of the dry heating electric faucet is too hot, a power supply is disconnected, thereby avoiding overcurrent damage caused by dry heating without water and short circuit, and protecting a heating device.
Description
Technical field
The utility model relates to a kind of fuse connection structure of electric hot water tap; It is the terminal that utilizes two separation in the fuse metal connecting circuit; These two terminals are electrically connected and connection circuit, and when current overload, when circuit is overheated, or external environment condition is overheated; The fracture of this fuse metal, the state that circuit is become open circuit.
Background technique
The use of electricity has become modern humans society and can not the missing link, the use of power equipment be looped around life arround, especially computerization, informationalized industry, at home, traffic, education, amusement or the like, do not have electricity especially and do not become.Relative, the electricity consumption that makes of safety also is that the modern have to be cautious.
In general; In the integrated circuit loop of power supply unit, be provided with the main switch of power supply control; Usually main switch is provided with safety fuse cutout or circuit breaker for the state of energising on it, when the electrical equipment that uses in the integrated circuit loop too much causes situations such as current overload, short circuit, circuit be overheated; Utilize blown fuse or circuit breaker escape and form the turnoff state in integrated circuit loop, ensure the safety of electricity consumption.
Electric hot water tap is made up of faucet body and flow control switch.And there are heating chamber and electrical equipment control chamber in the inside of faucet body wherein; Heating chamber and control chamber then are then to be to come to separate with sealing plate; The inside of control chamber is a heater circuit; In heating chamber the inside be power usually at the heating pipe of 2-3KW, just can heat in the time of second at 5-10 and hot water, heating pipe is connected on the heater circuit.
The characteristic of electric hot water tap is exactly: the heating pipe in the heating chamber is the insulation heating pipe, also is the isolated heating pipe of water power.Then the faucet body major part is that high-temperature engineering plastics is made, fraction be metal.
The function of the electric heating fire hose is exactly instant-heating, cold, hot two-purpose.Advantage be exactly fast, convenience, safety, energy-conserving and environment-protective, attractive in appearance or the like.Mainly be to be used in kitchen and Rest Room, conveniently wash the dishes, wash one's hands, wash one's face or the like, can let family all have hot water to use always.
But unexpected electric leakage also can appear in electric hot water tap sometimes, causes short circuit, or anhydrous dry combustion method, causes water tap to damage, and also possibly cause fire when serious, and human body is damaged.
The model utility content
The technical problem that the utility model solves provides a kind of fuse structure, and electric hot water tap can be used safely.
For solving the problems of the technologies described above; The technological scheme that the utility model adopts provides a kind of fuse structure of electric hot water tap; Comprise the heater circuit of electric hot water tap water storage cavity, heating tube and control heating tube heated condition, it is characterized in that, be connected with metal tube on the said electric hot water tap heating tube; Said metal tube one end is connected on the electric hot water tap heating tube; The other end opening is provided with the heat conduction safty device, and said heat conduction safty device comprise two terminals, and said two terminals are electrically connected and are series on the heater circuit of electric hot water tap; Be provided with fuse metal between said two terminals two terminals are electrically connected, said fuse metal had the characteristic of thermal cut.
The beneficial effect of the utility model is: the terminal that utilizes two separation of electric hot water tap in the fuse metal connecting circuit; These two terminals are electrically connected and connection circuit, when current overload, when circuit is overheated, or dry combustion method; When the electric hot water tap heating tube is overheated; The fracture of this fuse metal, the state that circuit is become open circuit has been protected heating equipment.
As the improvement of the utility model, said metal tube is copper pipe or aluminum pipe.
As the improvement of the utility model, said fuse metal is a strip, has the characteristic of thermal cut.
As the improvement of the utility model, said fuse metal is the low-melting alloy of low melting metal element Bi, Sn, In composition.
As the improvement of the utility model, said fuse metal has the characteristic of the excessive fusing of electric current.
