Abstract
The utility model relates to an electric heater, which can enlarge the control range for the boiling temperature of the liquid. The inside of a container is provided with an electric heating pipe welded with a flange, and the electric heating pipe is connected with a thermostat in series and then connected with a power supply. The utility model is characterized in that a heat conducting plate is welded between the middle point of the electric heating pipe and the flange; the thermostat arranged outside the flange clings to the heat conducting plate for fixing. The middle point of the electric heating pipe and the upper side of the heat conducting plate are provided with a metal cover with small holes to form an air chamber. Expanding temperature can be obtained by changing the sizes of the small holes and the sectional area and length of the heat conducting plate. During burning, the electric heating pipe can be protected. Because the range of temperature control can be expanded, the thermostat can be used with low accuracy for reducing cost and error control rate.
Description
The utility model relates to electric heating appliance.
Have in the liquid electric heater of temperature control in prior art, comprise beverage electric heater, electric hot water bottle and electric water boiler, its common design feature is all to have temperature controller, and they utilize the heat conduction of liquid or the thermal shock of boiling steam to realize temperature control.Utilize liquid heat conducting, narrow because of liquid boiling temperature, often be lower than ± 1 ℃, easily cause mistake control and out of control, this just needs the high-precision temperature controller of configuration or pressurization enlarges the control temperature to liquid, and this will improve manufacture difficulty and cost greatly.And utilize the steam temperature control then often concerning the electrothermal tube of thermal source below container, and when not adding liquid, do not have steam to produce and cause uncontrollablely, cause electrothermal tube to damage.
Task of the present utility model is to overcome the defective of prior art and proposes a kind of electric heater that enlarges the liquid boiling temperature control range; it will reduce the manufacture difficulty and the manufacturing cost of temperature controller product significantly; enlarge the temperature control scope in the time of not only can making liquid boiling, and the protective effect can do the electrothermal tube dry combustion method time.
Task of the present utility model is achieved in that it comprises container, with the electrothermal tube of flange welding one be connected to power supply after temperature controller is connected, its special character is to be welded with heat-conducting plate between the mid point of electrothermal tube and flange, make the temperature controller that is arranged on outside the flange be close to the interior heat-conducting plate of flange, and the metal cap with aperture is set on electrothermal tube mid point and heat-conducting plate.
According to the position difference of flange and relevant other part setting thereof, can be located at the bottom of the sidewall or the container of container.
This can enlarge the electric heater of liquid boiling temperature control range; control temperature in the time of can enlarging ebuillition of heated liquid; can when dry combustion method, protect electrothermal tube again; temperature controller is used when hanging down precision; reduce the manufacturing cost and the manufacture difficulty of temperature controller greatly; simplified the structure of liquid electrical heating temperature control and dry combustion method protection, thereby mistake control and rate out of control are reduced at double.
Fig. 1 is the utility model embodiment 1 structural representation.
Fig. 2 is the utility model embodiment 2 structural representations.
Be further elaborated again according to above-mentioned accompanying drawing embodiment.
The container (1) that can enlarge the electric heater (referring to Fig. 1-2) of liquid boiling temperature control range comprises bowl, kettle, thermos bottle, thermos cup, heat-preserving container and so on.Electrothermal tube (2) is housed in the container, it and metal method for making orchid (4) are welded one, between electrothermal tube mid point and flange, be welded with red copper system heat-conducting plate (5), and the metal cap (3) with aperture is set on them, form a steam chest, be fixed on the outer temperature controller (6) of flange (4) and be close to the interior heat-conducting plate (5) of flange (4).The size of metal cap (3) aperture and the sectional area of heat-conducting plate (5), length are all decided by electrothermal tube (2) amount of capacity.Electrothermal tube (2) be connected to power supply after temperature controller (6) is connected.
According to the different structure of electric heater, its metal flange (4) and relevant other part thereof comprise that heat-conducting plate (5), metal cap (3), temperature controller (6) can be arranged on the sidewall of embodiment 1 container (1), or are located at the bottom of embodiment 2, and its electrothermal tube coils respectively
Type or
Type.
In container (1), fill with water during use, connect with the mains, electrothermal tube (2) is started working, wait to reach 100 ℃ of water boilings, steam is full of steam chest and has repelled the water in the steam chest, because the difference of steam thermal conductivity, the temperature that makes the electrothermal tube central point is continued to rise to more than 100 ℃, and reach temperature controller (6) by heat-conducting plate (5), impel the temperature controller power cutoff, go up the size of aperture and the sectional area and the length (being the distance of electrothermal tube and flange) of heat-conducting plate (5) as long as change metal cap (3), can obtain different expansion temperature.Do not add water as container and connect with the mains, then the work high temperature of electrothermal tube (2) reaches temperature controller (6) power cutoff immediately by heat-conducting plate (5) immediately, thereby reaches the effect of protection electrothermal tube.
Claims (2)
1, a kind of electric heater that enlarges the liquid boiling temperature control range, comprise container (1), electrothermal tube (2) with flange (4) welding one is housed in the container, electrothermal tube be connected to power supply after temperature controller (6) is connected, it is characterized in that between the mid point of electrothermal tube (2) and flange (4), being welded with heat-conducting plate (5), make the temperature controller that is located at outside the flange be close to the interior heat-conducting plate of flange, and the metal cap (3) with aperture is set on electrothermal tube mid point and heat-conducting plate.
2, the electric heater that enlarges the liquid boiling temperature control range as claimed in claim 1 is characterized in that described flange (4) and relative part in addition can be arranged on the sidewall or the bottom of container (1).
