Description

The multipurpose baking oven

Affiliated technical field

The wood utility model relates to baking oven, but particularly a kind of roast duck, spit are roasting and the multipurpose baking oven of roasting pig.

Background technology

In the prior art, can be described as diversifiedly in order to the version of the baking oven of roast duck, roasting pig, but traditional baking oven by fuel with the charcoal is just progressively replaced by the gaseous fuel baking oven.Gaseous fuel baking oven commonly used is made up of body of heater, burner, hitch and chimney, because it is relatively simple for structure, there is the shortcoming that baking is inhomogeneous and cooking level is difficult to grasp always, can only rely on skilled master worker to go by rule of thumb to handle, careless slightly, just have influence on the quality of roast, be unfavorable for that more new hand goes operation.In addition, for the ease of controlling the quality of roasting thing, the purposes of existing baking oven is more single, can not handle roasting thing not of uniform size in same baking oven, and this is the deficiency of prior art just.

Summary of the invention

The purpose of this utility model is to solve the problem that existing baking oven exists, provide a kind of easy to operate, baking evenly, baking quality is good, and can toast the multipurpose gas baking oven of various foods.

Task of the present utility model realizes by this way: this baking oven includes hot-blast stove, Gas Pipe, safety valve, electric-controlled switch, the casing of air blast and baking box and chimney, it is characterized in that being provided with a thermal-arrest air chamber that is connected with warm-air pipe at bottom half, be respectively equipped with escape pipe at the upper spacer center of hot gas chamber and have the vertical side escape pipe that goes out air cleft with one, last escape pipe is placed in the side escape pipe, upper end closed between two pipes, be provided with one in a side of baking box and be communicated with and have the vertical other air inlet pipe that goes out air cleft with the thermal-arrest air chamber, on the upper spacer of thermal-arrest air chamber, be provided with an axial flow blower that drives by box outside motor, last escape pipe, the lower end of side escape pipe and other air inlet pipe is equipped with a blasting vane wheel that is driven by box outside motor, in the casing of chimney lower end, be provided with a blast pipe that has vertical suction slot, be provided with ventilating fan on its top, be provided with a disc type at box top and hang the thing rotating mechanism by driven by motor.

The purpose of this utility model also can take following measure to realize:

It is to be linked with a rotating shaft that is connected with motor by an arc top cover and circular extension thing dish that described disc type is hung the thing rotating mechanism, and the pulley bearing by the arc top cover edge is on the annular groove on casing top.

The described circular thing dish of hanging is linked by three annulus and a cross, is respectively equipped with several hooks on each annulus, also is provided with some crosspieces between outer shroud and secondary ring.

Each hook of hanging the thing dish in circle is connected with the timer that has display lamp on placing arc top cover by a connecting rod, in the rotating shaft of this timer, be provided with a sawtooth gear, a tooth bar that is engaged with is with on the hinged pull bar in its lower end, these both sides, pull bar upper end are connected with the timer fixed mount of top by two springs, between tooth bar bottom and pull bar, be provided with a back-moving spring, on pull bar, be provided with regularly scale.During use, pull bar leave behind by rule of thumb to required stoving time, just driving tooth bar when pull bar is left behind moves down, driven wheel rotates, make the time that timer is set to be needed, when people loose one's grip, go up, because gear and tooth bar all adopt saw shape tooth at the spring action lower link, and back-moving spring makes tooth bar have certain elasticity, and tooth bar not driven gear rotates.Arrive back connection bulb power when time of setting, allow people know that this roast bakes, thereby realize automatic Presentation Function.

The air cleft place that goes out in other air inlet pipe also is provided with the guide pipe that a symmetry is opened two straight-through air clefts, and the central shaft of this guide pipe drives swing by the motor that is arranged at the case top by toggle and fork.When the driven by motor crank rod movement, connecting rod just drives fork and swings around central shaft, because central shaft and fork link together, swings repeatedly in an angular range thereby make central shaft drive guide duct, the guiding hot blast is ejection outward in a fan-shaped range, reaches better baking and burns effect.

The utility model is work like this: the electric-controlled switch of opening combustion gas during use, feed combustion gas toward hot-blast stove, light the back and start air blast, allow hot-blast stove produce the bottom thermal-arrest air chamber that hot blast is sent into oven, wherein a part of hot gas turn in the burner hearth through going out to go up tracheae again; The heat of another part enter in the burner hearth from its vertical air cleft that goes out through the side escape pipe, the hot gas of some enters in the burner hearth through the air cleft that vertically goes out of other air inlet pipe from pipe of burner hearth one side again; And the axial flow blower that is arranged on its hot gas chamber dividing plate is constantly carried part hot gas up in burner hearth.This shows, the center in burner hearth, side and all have hot gas to send in the stove up and down, and the hot gas in the stove is through sucking in it from the vertical row air cleft of blast pipe and discharge outward from chimney by constantly circulating the back at stove.Therefore, air inlet and exhaust all are very uniform, almost do not have dead angle or localized hyperthermia district, can make the roast of suspension obtain very uniform cured effect.In addition, because the utility model also is provided with regularly display unit on the hook of hanging thing machine machine transmission mechanism, can put into practice according to experience, behind the setting stoving time, the time one know that to showing by light this roast dries by the fire, has guaranteed baking quality.In sum, the utlity model has the temperature inside the box and be evenly distributed, baking quality is reliable, can control stoving time automatically, and can toast very advantage such as fast cooling of different roasts and blowing out temperature in same stove.
