Description

Electric heating stove with parallel control knob

The utility model belongs to home electrical heater, particularly electric-heating cooking utensil.

Two control handles of existing electricity (heat) ripple stove product all are the upper and lower two-layer control boxes that are installed in of branch, the time control elements--timer is on the upper strata, and temperature control element--temperature controller is in lower floor.Wherein, the timer knob that has is installed in the top of control box, and the timer knob that has then is installed in the side of control box, and the thermostat knob then is installed in the lower floor of control box, and its pattern is half hidden that knob has part Be Controlled box to hide.The controller indicator light of existing product all fails to aim at its respective knob, and two indicator lights that have are installed in timer knob both sides, control box top, and are far apart from the thermostat knob; Then two indicator lights that have are installed in the both sides of timer knob, from the thermostat knob of lower floor one segment distance are arranged also.Like this, the control section indication of existing electricity (heat) ripple stove is indeterminate, uses inconvenient.Simultaneously,, not only be not easy to stir knob because the thermostat knob is half hidden, and because the scale on the knob has part covered, so scale reading is also inconvenient, not directly perceived.

The purpose of this utility model is to overcome shortcomings such as the indication of existing electricity (heat) ripple stove control section is indeterminate, use is inconvenient, scale reading is not directly perceived, and a kind of electric heating stove with good looking appearance block form control handle generous, rational in infrastructure, easy to use is provided.

Major technique of the present utility model thes contents are as follows: the structural representation of block form control handle electric heating stove as shown in Figure 1, it is mainly by body of heater 13, compositions such as pot body 2 and rack 15, on the pot body 2 handle 12 and foot rest 1 are installed, rack 15 is placed in the pot body 2, body of heater is made the pot cover form, body of heater 13 tops thread connection motor cabinet 5, accompany tempered glass lid 3 between them, there are control box 6 and motor 8 in motor cabinet 5 tops with thread connection, with thread connection timer 7 is arranged on the control box 6, big blade 11 and little fan blade 9 are housed on the output shaft of motor 8, axle head is fixed them with nut, there is electrothermal tube 4 outer ring of body of heater 13 with bolt, in the middle of the electrothermal tube is big blade 11, and thermostat 10 is fixed by bolts near the body of heater 13 top electrothermal tubes 4, and there is protective cover 14 body of heater 13 belows with thread connection, see through transparent tempered glass lid 3, can observe cooking process.Protective cover 14 upper punches have many apertures, heat supply air communication mistake.Electric wiring connection layout of the present utility model as shown in Figure 2, its operation principle is: according to different food and different tastes, with the selected suitable temperatures of thermostat 10, with the 7 selected suitable times of timer.After the energized, timer and

thermostat indicator light

16,17 are simultaneously shinny, the heat efficiency can reach 90% tubular metal electrothermal tube 4 and begin heating, be contained in centrifugal turbine fan blade 9 and 11 on the output shaft of motor 8 and stir near the electrothermal tubes high-temperature gas, form high temperature eddy flow heat wave and send into pot body 2, the food on the rack 15 is placed in baking.The operating state of electrothermal tube 4 is controlled by flashing temperature-control device 10, when the temperature in the pot body 2 rises to the temperature of pre-selected, and the thrermostatic bimetal-plate temperature distortion in the thermostat, actuating spring cuts off circuit, makes electrothermal tube stop heating, at this moment, thermostat indicator light 17 extinguishes.Reduce to when with selected temperature 10～20 ℃ of differences being arranged when temperature, thrermostatic bimetal-plate restores to the original state, and actuating spring is connected circuit, and electrothermal tube is generated heat once more, and the thermostat indicator light is shinny once more.Circulation so repeatedly remains in the selected temperature scope the interior temperature of pot body.Motor worked without cessation in seclected time, so formed the forced action type heat circulating system, this temperature can reach 250 ℃ eddy flow heat wave cooking food, and effect is splendid.The operating time of motor and electrothermal tube is subjected to the control of heat-resisting formula mechanical timer 7, and after arriving seclected time, general supply is cut off in the timer action, has finished cooking of food therein.

Principal character of the present utility model is a block form control handle part.Fig. 3 is that the E of Fig. 1 is to view.Fig. 4 is that the A-A of Fig. 3 is to cutaway view Amplified image.Block form control handle part mainly is made of jointly control box 6, timer 7, timer knob 18, timer indicator light 16, thermostat 10, thermostat knob 24, thermostat indicator light 17 and made of one piece nameplate 25 etc., their interconnected relationship with locations of structures is: timer knob 18 and arranged side by side arrangement identical with thermostat knob 24 profiles is installed on the top of control box 6, and the

indicator light

16,17 of timer and thermostat is stuck on the control box respectively over against timer knob 18 and thermostat knob 24; The

dial

19,23 of timer and thermostat,

title board

20,22, product brand board 21 grades are made made of one piece nameplate 25, stick on the control box top.Connect with a connecting rod 26 between thermostat knob 24 and the thermostat 10,, and be shaped on identical alignment pin 27 because an end and timer 7 axle head structures that connecting rod 26 cooperates with thermostat knob 24 are identical.Like this, thermostat knob 24 is made for the identical general part of contour structures with timer knob 18.

The utility model is compared with existing electricity (heat) ripple stove, and have following advantage and effect: (1) is arranged in juxtaposition owing to control handle, and is identical embedded type knob on the contour structures, so compact conformation not only, good looking appearance, and assemble easy, convenient and practical; (2) aim at the control corresponding knob respectively and indicate clearly owing to each indicator light; (3) unified general because of two kinds of control handles, the control box profile constitutes with circular arc and straight line, all makes production, manufacturing easy, can reduce product cost; (4) because two control handles are installed on the control box top side by side, two indicator lights are respectively over against corresponding knob, therefore, dial, controller title board, product brand board etc. can be made the made of one piece nameplate, so not only assemble easy, and the nameplate space of a whole page can unify the design, the printing, it is specious, effective, be that the rational of function demonstrates fully in the product design, it melts utility function and decorative effect in one; (5) the thermostat knob is installed on the top of control box, stirs conveniently, and dial reading is directly perceived.
