Description
Technical field
The present invention relates to fuel gas oven, especially the delivery temperature adjusting device of fuel gas oven.
Background technology
Fuel gas oven be in an equipment, possess simultaneously baking box portion, grill portion, on burner portion, have the advantage that various cookings are made simultaneously, use amount increases gradually in family or institute of business factory.
As shown in Figure 1, the structure of the fuel gas oven of prior art is generally: downside being provided with of fuel gas oven utilizes vertical firepower and heat mainly to carry out the baking box portion 1 of barbecue, the upside of baking box portion 1, be provided with the grill portion 2 of utilizing thermal convection current mainly to bake fresh fish, the top of grill portion 2 be provided with expose upside can place heating splendid attire food container a plurality of burners 3 on burner portion 4.In addition, the back of fuel gas oven is provided with the back of the body protective cover 5 of discharging the exhaust that produces in baking box portion 1 and the grill portion 2 to the outside, and the back of baking box 1 is provided with barbecue motor (not shown) and convection motor (not shown).
Fuel gas oven with said structure, when the user carries out cooking such as barbecue or bread, the cooking in baking box portion 1; When baking soft roastings such as fresh fish, utilize grill portion 2 to arrange; The general cooking that food in being contained in container heats, the burner 3 of the last burner portion 4 that utilizes that top exposes is arranged.
But the fuel gas oven of prior art has following weak point: the first, and the flame that takes place in the burner 3 of last burner portion 4 reveals the outside, and the danger of breaking out of fire is arranged; The second, during heat food, the soup that is contained in the container flows out, and fire is extinguished; The 3rd, soup or foreign matter are blocked the cigarette hole easily, and the bad phenomenon of burning takes place; The 4th, the pernicious gas that produces during burning is sucked in a large number by the user; The 5th, must all dismantle relevant parts during cleaning, cleaning is inconvenient.
Developed the fuel gas oven of hiding burner for the problems referred to above that solve fuel gas oven, the heater coil that utilizes electricity to heat replaces going up the burner of burner portion, burner top covers with glass-ceramic, and the radiant heat heating that takes place when heating by heater coil is placed on the food above the glass-ceramic or contains the container of food.But the fuel gas oven of hiding the burner form exists the electrical loss of heater coil bigger, and uneconomic shortcoming is unwilling to use in the general family.
No matter open wide the fuel gas oven of burner form or the fuel gas oven of hiding burner form, when all using baking box portion, grill portion, last burner portion simultaneously, shown in the arrow among Fig. 2, the thermal current of the high temperature that produces in baking box portion and the grill portion rises, cause that easily misoperation appears in heater block, make component life shorten reliability decrease.And heating is when discharging by the exhaust outlet of back of the body protective cover 5 with the exhaust of high temperature, and user's hand be vulnerable to scald, and there is the danger of the fire that causes in the exhaust of high temperature during near exhaust outlet.

Cold air dispatch tube 622 transmits from the air of cold air blowing fan 602 air-supplies such as the metal body of formalizing shape or flexible pipe, no matter Any shape can.
Be provided with the directly branched pipe 631 of supply cold air of protective cover 400 of supporting or opposing in the cold air dispatch tube 622.
As shown in Figure 7; cold air supply adjusting device 700 is by being arranged on the back of the body protective cover 400 inboard temperature sensors 701 that detect the protective cover 400 inboard delivery temperatures of discharging that support or oppose, and constitutes to the damper 702 of the air conditioning quantity of branched pipe supply in the inlet portion adjustment of branched pipe 631.
The action of the fuel gas oven that possesses the delivery temperature adjusting device of the present invention with said structure is as follows:
The user carries out cooking in baking box portion 100 when roasting or bread etc. are cooked, utilize grill portion 200 to cook when baking softness such as fresh fish barbecue, in last burner portion 300, cook when food is contained the general cooking of heating in the container, baking box portion 100, grill portion 200, go up burner portion 300 and can cook separately or cook simultaneously.
At first, action when cooking in the last burner portion 300 is as follows: pack into the cooking-vessel of gratin of the top placement of glass-ceramic 302, start Action Button, driving according to motor 358, blowing fan 357 is rotated, air is fed to gas mixing pipe 354 by air supply pipe 356, the combustion gas that meanwhile is fed to feed tube 355 is fed to gas mixing pipe 354 by nozzle 355, combustion gas and air flow into and mix simultaneously to the inboard mixing chamber M of combustion gas 351, the mist that mixes is by 352 ejections of burner mat, and the ignition flame that produce in igniting and the detector 353 this moment causes the burning of a little fighting.Combustion of mixed gas burner for heating mat 352, radiating spokes ejected wave in the heated burner mat 352, the radiated wave of radiation sees through glass-ceramic 302 cooking containers, and the gratin that is contained in cooking-vessel is cooked.
The burning gases of burner for heating mat 352 are discharged by being formed between burner lid 304 and the glass-ceramic 302 exhaust passage 303 that the forms protective cover 400 of supporting or opposing, and are communicated with the combustion gas of discharging and are by aiutage 306 protective cover 400 of supporting or opposing to discharge in aiutage 306 and burner lid 304.
When cooking; for overheated upwards burner portion 300 and the back of the body protective cover 400 that prevents instrument send cold air; this moment, action was; start the Action Button of instrument; the cold air blowing fan 602 of cooling end 600 is rotated; according to the rotation of cold air blowing fan 602, be drawn into suction space 613 by the cold air that sucks through hole 614 outsides.In addition; the cold air that sucks is upwards to blow cold air path 625 inboards of burner portion 300 by cold air dispatch tube 622; the cold air that transmits is by the downside supply of cold air supply orifice 624 to burner lid 304; the cold air that transmits is discharged with exhaust by the air tap 311 that is formed on shell 301 back protective cover 400 inboards of supporting or opposing; the cold air of above-mentioned transmission is to the following side flow of burner lid 304; each parts can not be heated, and the protective cover 400 of supporting or opposing is discharged the exhaust that is cooled.
The inboard of back of the body protective cover 400 is provided with the temperature sensor 701 that periodically detects delivery temperature; the value of setting in delivery temperature value that detects and the microcomputer (not shown) compares; delivery temperature is higher than setting value and sends actuating signals to the damper 702 that is arranged on branched pipe 631 inlet portions when above; the inlet portion aperture area of branched pipe 631 is enlarged; make by the branched pipe 631 more outside cold air of protective cover 400 supply of supporting or opposing, reduce the delivery temperature of back of the body protective cover 400.
In the above-mentioned course of action, by periodically detecting delivery temperature in temperature sensor 701, its delivery temperature value starts the upwards more cold air of burner 300 supplies of damper 702 in setting value the time once more.
