Description

Health-care electrothermal thermos

The utility model relates to a kind of household electrical appliance, particularly a kind of electric-heating thermos.

China Patent No. 88214703.X discloses a kind of fast automatic electric-heating thermos, formed by shell, inner bag, electrothermal tube, thermostat and drainage switch, it is characterized in that inner bag is aluminum products, electrothermal tube places inner bag, priming apparatus is arranged above the inner bag, heating by electrothermal tube reaches water boil, and supply is drunk.Its shortcoming is when opening drainage switch, and the cold water of priming apparatus flows directly into inner bag, the drinking-water temperature is descended, thereby do not reach the boiling point coolant-temperature gage; In addition, priming apparatus always will store cold water, otherwise, often burn out electrothermal tube, and can not use.

The purpose of this utility model solves the deficiencies in the prior art exactly, and a kind of maintenance drinking water boiling point is provided, even do not had water in the inner bag, also can not burn out the electric-heating thermos of electrothermal tube.

The utility model is made up of shell, inner bag, thermostat, drainage switch and electro-heat equipment.Electro-heat equipment is made up of heat-generating disc, radiation reflection basin and heat-barrier material, and the surface of heat-generating disc is certain radian, and there is a fixed leg centre, place in the radiation reflection basin, one inner bolt hole is arranged on the fixed leg, be fixed with thermostat, electro-heat equipment is fixed on the outer casing base with the bakelite pin.Be cast with alusil alloy and two electrothermal tube in the heat-generating disc, radiation reflection basin upper end tightly is with interior cover, is filled with insulation fibre between interior cover and inner bag, between heat-generating disc and the radiation reflection basin one deck heat-barrier material is arranged.Inner bottom part one side of shell is supply socket, opposite side is power switch and drainage switch, heat-generating disc tightens the inner bag that certain radian is arranged at the bottom that coincide, respectively there is a permanent magnet both sides of inner bag, place a micro-iron core and an arenolite in the inner bag, one cooling tank is arranged at the top of inner bag, is the boiled water switch below.

Operating circuit of the present utility model adopts indicator lamp Xb, K switch ₁, electrothermal tube RL ₁, and thermostat W be composed in series article one branch road, indicator lamp Xb, K switch ₂, electrothermal tube RL ₂, and thermostat W form the second branch road, after two branch road parallel connections, be connected on the mains supply.

The utility model is owing to adopted phase-change accumulation energy potential big, the alusil alloy that hot melt is big is made the energy-storage travelling wave tube of heat-generating disc, and has used heat-insulating material, and a radiation reflection basin that hemispherical surface is highly polished also has been installed, the heat energy that sheds, most it is lost to all around to have reduced heat energy by the reflection of radiation reflection basin, and insulation fibre is arranged around inner bag simultaneously, play the heat-insulation and heat-preservation effect, therefore, the utlity model has the higher thermal efficiency, reach 85～90%.The utility model adopts and heats indirectly, and when the water in the inner bag arrived boiling, temperature controller is automatic disconnection just, stops heating.Even there is not water in the inner bag, under the situation of energising, the temperature of heat-generating disc arrives one regularly, conducts to temperature controller by fixed leg, at this moment, temperature controller promptly disconnects, like this, even there is not water in the inner bag, can not burn out electrothermal tube yet, have nourishing healthy, energy-conservation, safe characteristics.

Below in conjunction with accompanying drawing, the utility model will be further described.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is an operating circuit schematic diagram of the present utility model.

Fig. 1 is a most preferred embodiment of the present utility model.The shell of heat-generating disc 10 is to become the surface that certain indent radian is arranged with urib founding, and it is horn-like that profile is, with small one and large one (big RL of power ₁700W, little RL ₂300W) electrothermal tube 8 and alusil alloy 9 cast directly in the heat-generating disc, and machining is carried out in the alusil alloy bottom surface.A tooth is arranged at the bottom of heat-generating disc, and the bottom of screwing on leaks when preventing the alusil alloy fusing, and there is the fixed cylinder 3 of a φ 10mm in bottom centre, and the external diameter of cylinder has a tooth.Hemispheric metal radiation reflection basin 7 inner surfaces are polished, outer surface is sprayed one deck heat resistance paint, heat-generating disc is packed in the radiation reflection basin, be lined with asbestos board 6 between the two, use the fixed by nut cylinder, cylindrical center screws down thermostat 2, like this, heat-generating disc, asbestos board, radiation reflection basin, thermostat just are fixed together, and are electro-heat equipment.Shell 15 can be made cylindrical shape or square, and outer casing bottom has three bakelite pin 1, and with the fastening electro-heat equipment of screw, bottom one side of shell is installed supply socket 5, and its opposite is power switch 23, indicator lamp 22 and boiled water drainage switch 21.The stainless steel inner container 12 of certain radian is arranged at the tight bottom that coincide on heat-generating disc, the micro-iron core 11 and the ore 24(that place a cone in inner bag contain germanium, zinc, selenium etc.), in process to boil water, discharge trace element, respectively there is one watt of type permanent magnet 14 both sides of being close to inner bag, cover 13 in the upper end of radiation reflection basin tightly is with a cylinder type metallic insulation insulation, in heat-insulation and heat-preservation, be filled with insulation fibre 16 between cover and the inner bag, prevent that heat scatters and disappears, upper port at inner bag has seal cover 17, in shell upper one openable lid 18 is arranged, one exhaust outlet 19 is arranged at the top of inner bag, the steam of discharging directly enters cooling tank 20 coolings, becomes distilled water, and a boiled water drainage switch is arranged in the inner bag bottom, one pallet 25 is arranged under the drainage switch, join with outer casing base 4.

The utility model is used as when heating rapidly, can be with K switch ₁, K ₂Close simultaneously, civil power is by indicator lamp Xb, to small one and large one electrothermal tube RL of power ₁, RL ₂Heating is simultaneously carried out temperature control by the thermostat W on the cylinder of bottom, when water temperature reaches 90 ℃, and just automatic disconnection of thermostat W, electrothermal tube RL ₁, RL ₂Stop power supply and heat, by the heat-generating disc energy stored, inner bag is continued to heat, make water reach boiling, because two electrothermal tube heats simultaneously, power increases, and the water in the inner bag can be boiled rapidly, and supply is drunk.

The utility model is used as when heating fast, with K switch ₁Close K switch ₂Disconnect, civil power is by indicator lamp Xb, electrothermal tube RL ₁With this branch road of thermostat W, when the inner bag that fills water reaches 90 ℃, just automatic disconnection of thermostat W, electrothermal tube RL ₁Stop heating, and by the energy storage of heat-generating disc inner bag is proceeded to heat, until water boil, can keep boiling temperature one hour, when temperature was lower than 90 ℃, thermostat W is conducting automatically again, each energising 2～3 minutes, thermostat W disconnects again, by the energy storage of heat-generating disc inner bag is proceeded to heat, and makes the water in the inner bag keep the boiling point state all the time.Used one day, power consumption is 0.8 degree, and the triangle brand electric heating that the South Sea produces electricity water bottle uses power consumption in a day 1.2 degree.

The utility model is used as when heating at a slow speed, with K switch ₁Disconnect, K closes a switch ₂, this moment, civil power was by indicator lamp Xb, K switch ₂, electrothermal tube RL ₂And this branch road of thermostat W, its course of work be used as when heating fast identical.
