The present application relates to ovens.
A conventional oven usually adopts a structure comprising an oven body and a support frame, wherein at least one air guide hole is defined at a lower part of the oven body, charcoal is directly placed into the oven body, a grid plate is arranged above the oven body, and thermal power and combustion efficiency of the oven is controlled via the air guide hole. However, this type of conventional oven depends on natural air flows excessively, in space where air is still or air flows are obstructed, the air guide efficiency may be very low, thereby resulting in too low combustion efficiency.
In order to overcome the drawbacks of the prior art, the present application provided an oven.

An oven comprising an oven body, wherein the oven body includes a housing, a combustion chamber, a grid plate, and a blower, the combustion chamber is arranged inside the housing, the grid plate is arranged above the housing, and the blower is communicated with the combustion chamber via an air channel.
The combustion chamber is substantially a cylindrical structure and includes a cylinder body, an upper cover arranged at an upper end of the cylinder body, a lower cover arranged at a lower end of the cylinder body, and a spacing piece arranged inside the cylinder body; an air distribution chamber is formed between the spacing piece and the lower cover, the spacing piece defines a plurality of air distribution holes, the lower cover defines an air channel hole configured to allow the air channel to communicate with the combustion chamber, and the upper cover defines a plurality of heat conduction holes.
The cylinder body defines a plurality of heat radiation holes.
The upper cover is provided thereon with a handle.
The housing is provided therein with a heat collection container, and the combustion chamber is arranged inside the heat collection container.
The housing defines a plurality of heat dissipation holes.
The blower includes a speed control circuit, and a side surface of the housing is provided with a speed control knob connected with the speed control circuit.
A bottom part of the housing is provided with a battery case, and the blower is powered by the battery case.
The blower can also be powered by a USB power supply unit, the USB power supply unit includes a power supply circuit board and a USB interface electrically connected with an input circuit of the power supply circuit board, and the USB interface is arranged on the housing.
A side surface of the housing is provided with at least one buckle device, and the grid plate is mounted at an upper end of the housing via the buckle device.
A periphery of the grid plate is provided with a fence.
The present application achieves the following advantageous effects: the oven comprises the oven body, wherein the oven body includes the housing, the combustion chamber, the grid plate, and the blower; the combustion chamber is arranged inside the housing and configured to accommodate barbecue charcoal, the grid plate is arranged above the housing and configured to place food, and the blower is communicated with the combustion chamber via the air channel, speeds of air flows in the combustion chamber are controlled by the blower, so that the present application can still be normally used in indoor environments or calm environments. Moreover, the blower is further provided with the speed control circuit and the speed control knob, which can adjust air flow precisely, so that thermal power can be well controlled and various barbecue effects can be achieved.
The present application will be further described below with reference to the accompanying drawings and embodiments.
