Description

multipurpose oven

Technical field

The wooden utility model relates to a roasting oven, in particular to a multipurpose roasting oven capable of roasting ducks, roasting skewers and roasting pigs.

Background technique

In the prior art, the structural forms of the ovens for roasting ducks and pigs can be said to be varied, but the traditional charcoal-fueled ovens are gradually being replaced by gas fuel ovens. Commonly used gas fuel ovens are composed of a furnace body, a burner, a suspension mechanism and a chimney. Due to the relatively simple structure, there have always been shortcomings such as uneven baking and difficulty in mastering the degree of rawness. A little carelessness will affect the quality of the baked goods, and it is not conducive to the operation of the novice. In addition, in order to control the quality of baked objects, the purpose of the existing oven is relatively single, and it is impossible to process baked objects of different sizes in the same oven, which is the deficiency of the existing technology.

Contents of the invention

The purpose of the utility model is to solve the problems existing in the existing oven, and to provide a multi-purpose gas oven with convenient operation, uniform baking, good baking quality and the ability to bake various foods.

The task of the utility model is realized in such a way: the oven includes a hot blast stove, a gas pipe, a safety valve, an electric control switch, a blower and a box and a chimney of the oven, and is characterized in that a There is a heat-collecting air chamber connected to the hot air pipe. In the center of the upper partition of the hot air chamber, an upper air outlet pipe and a side air outlet pipe with vertical air outlet slits are arranged respectively. The upper air outlet pipe is sleeved in the side air outlet pipe. The upper end between the two pipes is closed. On one side of the oven, there is a side air inlet pipe which communicates with the heat collecting chamber and has a vertical air outlet. Driven by the axial flow fan, the lower end of the upper air outlet pipe, the side air outlet pipe and the side air inlet pipe is equipped with a blower impeller driven by a motor outside the box, and there is a vertical air suction slot in the box at the lower end of the chimney. The exhaust pipe is provided with an exhaust fan at its top, and is provided with a disc type hanging object rotating mechanism driven by a motor on the top surface of the casing.

The purpose of this utility model can also be realized by taking the following measures:

The disc-type hanging object rotation mechanism is formed by connecting an arc-shaped top cover and a circular hanging object tray with a rotating shaft connected to the motor, and is supported on the top of the box by a pulley on the edge of the arc-shaped top cover. on the ring groove.

The circular hanging tray is formed by connecting three rings and a cross, and several hooks are respectively arranged on each ring, and several crosspieces are also arranged between the outer ring and the secondary ring.

Each hook of the circular hanging object tray is connected with a timer with a display light placed on the arc-shaped top cover through a connecting rod. A sawtooth gear is arranged on the rotating shaft of the timer, and a The meshing rack is hinged on a pull rod with its lower end, and the two sides of the upper end of the pull rod are connected to the upper timer fixing frame through two springs. A return spring is arranged between the lower part of the rack and the pull rod, and a timing scale is set on the pull rod. . When in use, pull down the pull rod to the required baking time according to experience. When the pull rod is pulled down, the rack will be driven down, and the gear will be driven to rotate to make the timer set the required time. When people let go, the spring will pull down the rod. Pick up, because gear and rack all adopt saw-shaped teeth, and back-moving spring makes rack have certain elasticity again, rack does not drive gear to rotate. When the set time arrives, the light bulb is turned on to let people know that the baked object has been baked, so as to realize the automatic display function.

The air outlet slit of the side air inlet pipe is also provided with a guide pipe symmetrically opened with two straight air slits. The central axis of the guide pipe is driven to swing by the motor arranged on the top of the box through the crank linkage mechanism and the swing rod. When the motor drives the crank connecting rod to move, the connecting rod drives the swing rod to swing around the central axis. Since the central shaft and the swing rod are connected together, the central shaft drives the air duct to swing repeatedly within an angle range, guiding the hot air in a Spray out within the fan-shaped range to achieve a better baking effect.

The utility model works like this: when in use, turn on the electric control switch of the gas, feed gas into the hot blast stove, start the blower after ignition, let the hot blast stove generate hot air and send it to the bottom heat-collecting gas chamber of the baking furnace, and part of the hot gas goes out The upper air pipe is then turned over into the furnace; another part of the heat is discharged into the furnace through the side air outlet pipe through its vertical air outlet slot, and another part of the hot air is discharged into the furnace through the side air inlet pipe on one side of the furnace from the vertical air outlet slot in the pipe In the furnace; and the axial flow fan installed on the partition of the hot gas chamber continuously transports part of the hot gas upwards into the furnace. It can be seen that hot air is sent into the furnace in the center, side, and up and down of the furnace, and the hot air in the furnace is sucked in from the vertical exhaust slot of the exhaust pipe after being continuously circulated in the furnace, and then discharged from the chimney. Drain out. Therefore, both the air intake and exhaust are very uniform, and there are almost no dead angles or local high temperature areas, so that the hanging baked objects can obtain very uniform baking effect. In addition, because the utility model is also equipped with a timing display device on the hook of the transmission mechanism of the hanging machine, according to experience and practice, after setting the baking time, when the time is up, you can know that the baked object has been baked through the light display. Transparent, to ensure the quality of baking. To sum up, the utility model has the advantages of uniform temperature distribution in the box, reliable baking quality, automatic control of the baking time, and the ability to bake different baked goods in the same furnace and quickly cool down at the shutdown temperature.
