Description

The electric calorifie installation of slow cooker

The utility model relates to a kind of electric calorifie installation, relates to a kind of suitable long-time electric calorifie installation to chafing dish or saucepan heating or rather.

Traditional saucepan is a simple pot body, and itself is not with heater, disposes the heater as gas oven, electromagnetic oven one class during use again.Because saucepan is the cooking container that needs long-time heating, is not suitable for the heater collocation use fast, otherwise can influences the local flavor of cooked food with firing rate.In addition; aim at the heater of saucepan design at present; the heating wire winding directly is connected in body of heater and with power supply; the heat energy and the power that are produced are fixed; owing to do not have temperature control and the function of regulating; thereby boil the problem that has temperature more and more higher in the process stewing, do not have the structural design of temperature protection aspect again, thereby very easily burn heating wire.Moreover, because exposing, heating wire adopts directly heating but not the conduction sensible heat, soup juice usually overflows trickling on heating wire, causes because of difficulty to cleaning.

The purpose of this utility model is a kind of slow cooker electric calorifie installation of design, and its heating arrangement adopts the mode of conduction sensible heat to design, and by the temperature control design, can do heating long-term and stably to saucepan.

The electric calorifie installation of slow cooker of the present utility model comprises body of heater and heating wire, it is characterized in that:

Described heating wire is outside equipped with insulation sleeve; Described body of heater comprises base, stove seat, heat shield, drum and heat conducting disk; Described heat conducting disk bottom center is provided with screw rod; The central position of described drum, heat shield, stove seat and base is provided with circular hole; Be equipped with on the described drum groove is set, the drum side is respectively equipped with temperature detect switch (TDS) and supply socket; Be respectively equipped with on the described stove seat with drum on corresponding temperature control knob and the perforate of temperature detect switch (TDS) and supply socket position; Described heating wire winding is provided with in the groove drum, and the screw rod of described heat conducting disk passes the circular hole on drum, heat shield, stove seat, the base successively, has that nut is locked between drum and heat shield, on the screw rod of between heat shield and base and base bottom.

On the described drum with groove corresponding position spaced set is set the fixedly stator of heating wire is arranged.

Send out the heating wire of putting in the groove on the described drum and be close to described heat conducting disk bottom.

Also include current-limiting resistance and indication neon lamp, current-limiting resistance is connected with the indication neon lamp, is connected in series in the AC power circuit with described temperature detect switch (TDS) again with after heating wire is in parallel.

Further specify technology of the present utility model below in conjunction with embodiment and accompanying drawing.

Fig. 6 slow cooker electric calorifie installation electrical schematic diagram;

Also combination is referring to Fig. 2 to Fig. 5 referring to Fig. 1, and the slow cooker electric calorifie installation mainly comprises heat conducting disk 1, heating wire 3, drum 4, heat shield 10, stove seat 11 and base 12.

The bottom center place of heat conducting disk 1 is installed with screw rod 2, drum 4 is provided with around shape groove 5 is set, and correspondence is provided with groove 5 equidistant dashing and establishes plurality of fixed sheet 6 on the drum 4, is used for fixing the heating wire 3 of winding in groove 5 is set, as shown in Figure 2, heating wire 3 outer cover are provided with insulation sleeve.One side of drum 4 is installed with a temperature detect switch (TDS) 9, has also extended socket 7 apart from temperature detect switch (TDS) 9 suitable drum 4 sides at a distance, and two conducting strip sides are arranged with insulating trip in the socket 7, and fixedly two-terminal 8 of screw is arranged in the socket 7.

The screw rod 2 of heat conducting disk 1 worn that the centre bore of line-crossing disk 4 and lock are established a nut and drum 4 is fixed on the bottom surface of heat conducting disk 1,3 bottom surfaces subsides with heat conducting disk 1 of the heating wire of winding on the drum 4 are touched, as shown in Figure 3.Then the centre bore of heat shield 10 is set on the screw rod 2 and with the fixing heat shield 10 of nut, and makes

drum

4 and 10 of heat shields keep suitable distances, as shown in Figure 4, can intercept the conduction of heat energy by air.Last be arranged on this combining structure on the stove seat 11 again and make screw rod 2 pass stove seat 11 bottoms and pass the centre bore that is positioned at stove seat 11 below bases 12, assemble and fix whole electric calorifie installation in the bottom of screw rod 2 with the nut screw lock again, as shown in Figure 5.

The temperature detect switch (TDS) 9 that drum 4 one sides are set, its axle that tunes switch can be by the hole on stove seat 11 panels, and with the knob combination of stove seat outside, then the jack with stove seat 11 is corresponding with terminal 8 for socket 7, make its can with the attaching plug binding of outside with the introduction power supply.

Referring to Fig. 6, heating wire 3 usefulness R represent among the figure, and specification is chosen as 180 watts/80 Europe, can select the specification of R by needed power output, can be less as the power of saucepan, and the power of chafing dish is then bigger, and temperature detect switch (TDS) K is used for adjusting the magnitude of current of R.It is in parallel with R to connect with indicator lamp L with current-limiting resistance r again in the circuit again, with the duty of neon lamp L indication heating wire R.

Electric calorifie installation of the present utility model, stove seat 11 itself adopts ceramic materials, has insulation, heat insulation effect.Temperature detect switch (TDS) 9 can make the heating wire R in 180 watts/80 Europe adjust to 230 degree at 0 degree, obtains stable heating-up temperature, suits especially to use in the slow cooker cooking.User replaceable heating wire R when reality is used uses for chafing dish.

The electric calorifie installation of slow cooker of the present utility model, the drum of winding heating wire is set in the heat conducting disk bottom, and wear heat shield and base with the screw rod of heat conducting disk center bottom, attaching nut and assemble whole electric calorifie installation again, its drum also is provided with the power output of temperature detect switch (TDS) with the control heating wire except that being provided with the socket that connects power supply, have add thermally-stabilised, temperature is adjustable, is suitable for stewing slowly for a long time, boiling, and is safe in utilization, convenient.
