Abstract

Embodiment of the present utility model relates to oven, and it comprises base, built-in base plate, air blast, oil drain pan, the box that ignites, deep bead, charcoal box and shell.The wind of bottom blast machine conveying, after deep bead reflection, enters the box that ignites.According to the utility model, the wind of bottom blast machine conveying reflects through baffle plate, makes wind-force softer lasting, thus prevents charcoal ash to kick up.

Description

Oven

Technical field

The utility model relates to a kind of oven, more specifically, relates to a kind of oven that can prevent charcoal ash from kicking up.

Background technology

Oven is also known as baking oven, charcoal brazier, and its operation principle utilizes air convection, and the heat utilizing the burning such as charcoal or environment-friendlycharcoal charcoal to produce takes heated food.But, due in air transfers heat process, the air themperature near charcoal dish can be caused higher, air themperature away from charcoal dish is lower, causes oven can not efficiently and equably cooked food, and produces a large amount of oil smoke and dust, charcoal burning is insufficient in addition, also can produce the toxic gases such as CO.

For the problems referred to above, Chinese invention patent CN104172942A discloses a kind of smokeless roaster, is connected, in flash pan, forms rotating wind by the air channel be obliquely installed with the side of flash pan, charcoal is burnt more abundant; And the bottom of charcoal dish is provided with along the direction of rotating wind in low early and high after skewed rotation protrusion, air vent is arranged on rotation protrusion, make the air stream of coming in from air channel more smooth and easy, and form whirlwind, make firepower more even, further make burning more abundant, thus reduce the discharge of smog.

But be similar to oven disclosed in above patent still to have problems in some aspects.Charcoal tray bottom air vent be arranged on arrange along rotating wind direction on low early and high after skewed rotation protrusion, that is the rotating wind formed in flash pan can directly enter charcoal dish, and forming whirlwind, the whirlwind so formed in charcoal dish just may cause charcoal ash to be kicked up.Meanwhile, the wind-force that fan provides does not continue, time time slack anxious, make charcoal combustion instability, easily cause burning insufficient.In addition in order to make full use of heat, adopt the casing of hollow, bracket is placed in top, puts coal placing disc in bracket, and the veritas ring burnt by charcoal is in the inner space of whole shell, and service time is long will cause that skin temperature is too high causes accident generations such as scalding one's hand.

Utility model content

In view of this, one of the purpose of this utility model is intended to solve existing oven and heats uneven, the defect that smoke emission is large.

The further object of the utility model is intended to the skin temperature reducing oven in heating process.

According to embodiment of the present utility model, provide a kind of oven.This oven comprises base, built-in base plate, be arranged at base middle position and the air blast between described base and described built-in base plate, the oil drain pan being arranged at the annular groove-shaped structure above described built-in base plate, the box that ignites, deep bead, be subject to described in ignite the charcoal box that box supports and the shell be positioned on described base, described shell surrounding surround described built-in base plate, described oil drain pan, described in ignite box and described charcoal box.The described box that ignites is suspended on the inward flange of the oil drain pan of described annular groove-shaped structure, and described deep bead is arranged on described built-in base plate and, ignite described in encirclement box at the end of described oil drain pan; Or described deep bead is arranged on described built-in base plate, and the outward flange of the opening formed through the inward flange of the oil drain pan of described annular groove-shaped structure and the box that ignites described in supporting and the main body of the box that ignites described in surrounding.

Inventor of the present utility model recognizes first in this area, it is suitable for setting up deep bead, the wind direction that deep bead is blower fan provides a reflecting surface, the wind-force provided due to fan does not continue, and wind-force can be relatively stable after reflection, can mitigation be become simultaneously, reduce charcoal ash and raise up.
