Abstract
The utility model relates to a safe type electric water heater which is provided with a heater casing, a heat conducting pipe and an electric heating pipe. The heater casing is filled with heat conducting liquid having the advantages of good insulation and stable performance, and the heat conducting pipe and the electric heating pipe are arranged in the heat conducting liquid in the heater casing. The heat conducting pipe turns in the heat conducting liquid, and the water inlet and the water outlet of the heat conducting pipe are extended out of the heater casing. The electric heating pipe is connected with the power supply out of the heater casing, and a self control thermostatic switch is arranged on the heater casing wall between the electric heating pipe and the power supply. When the utility model is used, the heat conducting liquid is heated by the electric heating pipe and controlled by the thermostatic switch to keep in pre-determined temperature; cold tap water goes from the water inlet and is heated by the heat conducting pipe; hot water flows out from the water outlet continuously. The utility model has the advantages of easy use, continuous flow, stable water temperature and safety.
Description
It is essential that the utility model relates to the human lives, is a kind of safety electric water heater.
A kind of electric heater is arranged in the market, be directly to touch charged scorching hot resistance wire when utilizing cold water to flow and make cold water be heated as hot water, though this electric heater has taked multiple measure to eliminate institute's belt current in the hot water, but still can not make people that this water heater is set up the sense that is perfectly safe.
The purpose of this utility model is to provide a kind of safety electric water heater, and this is that a kind of electricity that utilizes comes indirectly water to be heated to make cold water become the utensil of hot water rapidly, and hot water is perfectly safe.
The purpose of this utility model is achieved in that the safety electric water heater is provided with device shell, heat pipe, electrothermal tube, has filled with the conductive fluid of the stable performance of having insulated in the device shell; Heat pipe and electrothermal tube all are arranged in the conductive fluid in the device shell, and heat pipe is in the conductive fluid inside turn, and its water inlet and delivery port all extend to outside the device shell; The outer power supply of electrothermal tube and device shell links, and the device shell wall between electrothermal tube and the power supply is provided with the thermostat of automatic control.
The utility model is work like this.Before the use, water inlet and running water pipe should be connected, power line is received the thermostat place, and connect power supply to the conductive fluid preheating, electric current proceeds to electrothermal tube through thermostat and makes the electrothermal tube heating at this moment, causes the electric heating liquid temp to rise, when the temperature of electric heating liquid rises to predetermined temperature (for example 60 ℃), circuit is cut off in the automatic tripping of thermostat, and conductive fluid remains on predetermined temperature.During use, only need open running water switch, at this moment, cold water proceeds to heat pipe from water inlet, and during through heat pipe, constantly draw heat finally becomes the thermal water source seedbed and flows out from delivery port.In the use, whenever the temperature of conductive fluid has decline slightly, thermostat is automatic processing circuit immediately, and electrothermal tube is heated conductive fluid again, reaches predetermined value up to temperature.Conductive fluid remains at predetermined temperature, has also just kept the hot water temperature of flowing out stable.The heat of electrothermal tube is through the conductive fluid that insulate the water in the heat pipe to be heated, so hot water safety is not charged.
Characteristics of the present utility model are: easy to use, can flow out hot water continuously, water temperature stability, safety.
Further narrate below in conjunction with drawings and Examples.
Accompanying drawing is a structural principle schematic diagram of the present utility model.
Embodiment: referring to accompanying drawing, device shell (1) by inside and outside, in three layers constitute, internal layer is that the stainless sheet steel of thick 0.5MM is made, it is the airtight container of conductive fluid, skin is the plastics shell, the middle level is the polyvinyl chloride foams with good heat-proof quality, and the sealing of this device shell, thermal insulation are all good; Conductive fluid (2) is the transformer oil with the stable performance of having insulated, and it must be with heat pipe (3) and all submergences of electrothermal tube (5) in the device shell; Electrothermal tube power is 220V, 1.2 kilowatts; Heat pipe is that the copper tube of internal diameter 8MM external diameter 10MM is made, and the pipe range between water inlet (4) and the delivery port (7) is more than 1 meter; Thermostat (6) adopts the bimetallic temperature detect switch (TDS), and its automatic control outage temperature is 60 ℃.The electric heater of present embodiment, when running water flowed in heat pipe, it can be continuously confesses hot water more than 40 ℃ from delivery port.If running water switch is stubborn big or stubborn little, thereby the flow velocity that changes water just can reduce or the rising water temperature, realizes the adjustment among a small circle of water temperature.If with the thermostat place, work becomes two thermostat parallel connections, for example its automatic control outage temperature is respectively 60 ℃ and 80 ℃, handle which thermostat work by turn-knob, then can make safety electric water heater of the present utility model flow out more than 40 ℃ or the hot water more than 60 ℃, realize two grades of controls of water temperature.
