Description
Technical field
The utility model relates to heat-preserving container field, and particularly a kind of splendid attire congee, tea, rice etc. adopt electrically heated heat-preserving container.
Background technology
The heater element of existing electrothermal heat-preserving bucket adopts electrothermal tube usually, electrothermal tube is installed on the bottom of staving, electrothermal tube maintains Fast Heating state in energising situation always, caloric value is large, temperature rises sharply, and is easy to cause cement, spoon meat burns and stick to staving, after electrothermal tube power-off, because electrothermal tube surface area is larger, comparatively large with air heat-exchange area, therefore electrothermal tube can be lowered the temperature rapidly, causes heat insulation effect bad.
Utility model content
The purpose of this utility model to provide a kind of electrothermal heat-preserving bucket, and after overcoming heater element energising and power-off, the temperature of heater element rises sharply and the shortcoming of rapid drawdown, strengthens heat insulation effect.
According to an aspect of the present utility model, provide a kind of electrothermal heat-preserving bucket, comprise staving, interior bucket, heating wire and attemperating unit, heating wire is fixed on the bottom of staving, and is connected with attemperating unit, and interior casing in staving, and is supported in heating wire.
Its beneficial effect is: adopt attemperating unit to control heating temp and the caloric value of heating wire, and heating wire is less in the caloric value of unit are, during continuous heating, temperature rise is comparatively slow, and the cement in interior bucket, spoon meat are not easy to burn and adhere on it, prevent interior bucket sticky end, when heating wire cut-off lowers the temperature simultaneously, heating wire elongate form, less with the heat exchange area of air, be not easy rapid cooling, heat easily keeps, and enhances heat insulation effect.
In some embodiments, heating wire arranges at grade in the shape of a spiral, and insulation material layer parcel.
Its beneficial effect is: the setting of the coiling shape of heating wire, reduces the heat exchange area between heating wire and air further, adds the parcel of adiabator layer, prevent again the loss of heat further.
In some embodiments, adiabator layer is aluminium foil.
Its beneficial effect is: adopt aluminium foil as adiabator layer, heat insulation effect is better.
In some embodiments, be provided with support between heating wire and interior bucket, support and staving are fixed.
Its beneficial effect is: staving arranges support, for supporting interior bucket, heating wire and interior bucket is separated, and avoids interior bucket extrude and damage heating wire, is conducive to the caloric value integrated distribution of heating wire in bottom of the barrel.
In some embodiments, attemperating unit comprises temperature controller, power switch, power supply indicator and temperature control indicator lamp, temperature controller, power switch, power supply indicator, temperature control indicator lamp are all fixed on staving, power supply indicator is in parallel with power switch, and the series arm that temperature control indicator lamp and temperature controller form is parallel to heating wire and power switch.
Its beneficial effect is: turn on the power switch, and connect civil power, electrothermal wire heating, power supply indicator, temperature control indicator lamp are lighted, and regulates the temperature of temperature controller, makes the temperature of heating wire rise to this temperature value lentamente, and maintains this temperature value and be incubated.
The beneficial effects of the utility model are: adopt electrothermal wire heating, heat up and lower the temperature all comparatively to relax, and can either make interior bucket not sticky end, also enhance the heat insulation effect of electrothermal heat-preserving bucket.
Accompanying drawing explanation
Fig. 1 is the structural representation of the electrothermal heat-preserving bucket of the utility model one embodiment;
Fig. 2 is the structural representation bottom staving shown in Fig. 1;
Fig. 3 is the circuit diagram of attemperating unit shown in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 show schematically show the electrothermal heat-preserving bucket according to a kind of embodiment of the present utility model.
As shown in Figure 1, 2, this electrothermal heat-preserving bucket, comprise staving 1, interior bucket 2, heating wire 3 and attemperating unit 4, heating wire 3 spirally-wound, the center of heating wire 3 is compressed by pressing plate, then pressing plate is fixed on the bottom of staving 1 by screw, and heating wire 3 adiabator layer 5 wraps up, preferably, adiabator layer 5 adopts aluminium foil.
Interior bucket 2 is inserted in staving 1 from the open top of staving 1, interior bucket 2 coordinates with staving 1 closely, to prevent thermal loss, and interior bucket 2 can take out from staving 1, interior bucket 2 is for holding solid or cement, the spoon meats such as congee, tea, rice, tap 6 is clamped in the installing hole on staving 1, and convenient spoon meat of releasing from interior bucket 2 in it, solid, cement food then take out from the opening of interior bucket 2.
The support 7 of tripod shape is installed above the heating wire 3 that aluminium foil wraps up, three pin of support 7 are welded in the inwall bottom staving 1, support 7 for supporting interior bucket 2, thus makes interior bucket 2 keep certain gap with heating wire 3, avoids interior bucket 2 extrude and damage heating wire 3.
Attemperating unit 4 comprises temperature controller 8, power switch 9, power supply indicator 10 and temperature control indicator lamp 11, staving 1 is offered five installing holes, temperature controller 8, power switch 9, power supply indicator 10 and temperature control indicator lamp 11 are fixing through installing hole clamping accordingly, the knob portion of temperature controller 8, the button part of power switch 9, the indicator lamp part of power supply indicator 10 and the indicator lamp part of temperature control indicator lamp 11 are placed in the outside of staving, and the wire connecting portion of temperature controller 8, power switch 9, power supply indicator 10 and temperature control indicator lamp 11 is placed in the inner side of staving 1.Attaching plug 12 is placed in the outside of staving 1, and power line 13 passes from the installing hole of staving 1, access power switch 9.
As shown in Figure 3, power switch 9 is in parallel with heating wire 3, and power supply indicator 10 is in parallel with power switch 9, and the series arm that temperature control indicator lamp 11 and temperature controller 8 form is parallel to heating wire 3 and power switch 9.
As shown in Figure 1, 2, attemperating unit 4 connects 220V alternating current by attaching plug 12, press the button of power switch 9, power switch 9 closes, and power supply indicator 10 is lighted, temperature controller 8 is energized simultaneously, temperature control indicator lamp 11 is also lighted, heating wire 3 heating power, regulates the temperature of temperature controller 8 simultaneously, make the temperature of heating wire 3 rise to this temperature value lentamente, and maintain this temperature value and be incubated.
Temperature controller 8 is adopted to control heating temp and the caloric value of heating wire 3, and heating wire 3 is less in the caloric value of unit are, during continuous heating, temperature rise is slower, cement in interior bucket 2, spoon meat is not easy to burn and adheres on it, prevent sticky end, during heating wire 3 power-off cooling simultaneously, heating wire 3 elongate form, and adopt spirality coiling to form, reduce the heat exchange area between heating wire 3 and staving 1 bottom air, add the parcel of adiabator layer 5, effectively prevent thermal loss, therefore electrothermal heat-preserving bucket is not easy rapid cooling, heat easily keeps, enhance heat insulation effect.
Above-described is only embodiments more of the present utility model.For the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
