Abstract

The utility model discloses a furnace bottom structure of a barbecue oven and aims to overcome the defect in the prior art that air inlets of an ash receiving container are completely exposed towards the external part of the barbecue oven, so that certain carbon dust flies out of the barbecue oven from the air inlets. The key points of the technical scheme are as follows: the furnace bottom structure is composed of the ash receiving container and a charcoal accommodating disc, wherein the ash receiving container is arranged on a furnace bottom plate of the barbecue oven; the charcoal accommodating disc is placed in the top opening of the ash receiving container; the ash receiving container is placed on a lower opening of the furnace bottom plate and is exposed to the outer side of the furnace bottom plate from the lower opening; a plurality of air inlets are formed in the side wall, exposed to the outer side of the furnace bottom plate, of the ash receiving container; a plurality of vent holes are formed in the bottom of the charcoal accommodating disc. The structure is characterized in that an ash damper, which is oblique and extends downwards, is arranged on the inner side of each of the air inlets in the ash receiving container; an air inlet seam is formed by the bottom edge and two side edges of the ash damper as well as the inner side of each of the air inlets.

Description

A kind of bottom construction of oven

Technical field

The utility model relates to a kind of bottom construction of the functional structure of roasting on cooked food utensil, particularly a kind of oven.Be applicable to grilled oven and the roasting dual-purpose oven of grilled electricity of various shapes and structure.

Background technology

The oven that traditional barbecue cooked food is used, structure is a stove seat of containing charcoal, and furnace bottom does not have the structure of ventilating, and stove seat top mouth is provided with grill frame, during this oven combustion carbon, incomplete combustion easily occurs, and the thermal efficiency is not high, and heavier and simple and crude.No. 99240829.6 disclosed grilled, roasting dual-purpose stove of electricity of Chinese patent, furnace bottom does not have aeration structure yet.

The applicant is at the heater of a kind of electrical carbon dual-purpose oven of No. 201220367596.5th, the Chinese patent of first to file, at furnace bottom, be provided with ash container and the Sheng carbon dish that is placed on ash vessel top mouth place, ash container is housed on the lower port of described stove seat bottom surface and ash container exposes outside, described stove seat bottom surface from described lower port, the sidewall that ash container exposes described stove seat bottom surface Outboard Sections is provided with air admission hole, and Sheng carbon dish is tried to get to the heart of a matter and is provided with passage.Can be so that combustion during carbon, air admission hole the sidewall that air stream exposes from ash container enters, in ash container, from the passage of containing carbon dish, rise, for the charcoal of containing on carbon dish provides sufficient oxygen, can make the burning of charcoal more completely, effectively improve the thermal efficiency, when containing carbon ash that the charcoal burning on carbon dish produces and dropping from passage, for ash container is caught, with the carbon ash of fire point, fall outside stove avoiding.The defect of this technical scheme is: because the air admission hole of ash container is completely open outside stove, so carbon ash drops to ash container processes from the passage of containing carbon dish, some carbon ashes tend to fly out stove from air admission hole.

Summary of the invention

Completely open outside stove in order to overcome the air admission hole of ash container of prior art, carbon ash drops to ash container processes from the passage of containing carbon dish, the defect that some carbon ashes can fly out stove from air admission hole, the purpose of this utility model is to provide a kind of bottom construction of improved oven, can overcome the defect of prior art.

The utility model solves the technical scheme that its technical problem adopts: a kind of bottom construction of oven, by the Sheng carbon dish that is arranged on the ash container on the drop-bottom of oven and is placed on ash vessel top mouth place, formed, ash container is to be housed on the lower port of described drop-bottom, and ash container is exposed to described drop-bottom outside from described lower port, the sidewall that ash container exposes described drop-bottom Outboard Sections is provided with some air admission holes, Sheng carbon dish is tried to get to the heart of a matter and is provided with some passages, it is characterized in that: on described ash container, each air admission hole inner crest face of some air admission holes is equipped with the dust block board extending toward having a down dip, the base of dust block board and dual-side and place air admission hole inner side edge form air inlet sealing.

The described air admission hole of technique scheme and corresponding dust block board all can adopt the structure of essentially rectangular, also can adopt the structure of roughly trapezoidal or general triangular wide at the top and narrow at the bottom, and the gear ash effect of avoiding like this carbon ash to fly out stove from air admission hole is better.

On the described ash container of technique scheme, can be provided with handle, to facilitate from drop-bottom, take out ash container.

The beneficial effects of the utility model: because each the air admission hole inner crest faces of some air admission holes on ash container is equipped with the dust block board extending toward having a down dip, the base of dust block board and dual-side and place air admission hole inner side edge form air inlet sealing, so when carbon ash drops to ash container processes from the passage of containing carbon dish, those carbon ashes that approach ash container air admission hole can drop on dust block board, then being slipped to the position away from from air admission hole drops, the carbon ash amount that so just can fly out stove from air admission hole is reduced to a minimum, in fact can accomplish does not have carbon ash to fly out stove from air admission hole substantially.

The specific embodiment

With reference to Fig. 1～Fig. 3, the bottom construction of this oven, by a Sheng carbon dish 3 that is arranged on the ash container 2 on the drop-bottom 1 of oven and is placed on mouthful place, ash container 2 tops, formed, ash container 2 is to be housed on the lower port 4 of described drop-bottom 1, and ash container 2 is exposed to described drop-bottom 1 outside (i.e. below) from described lower port 4, the sidewall 5 that ash container 2 exposes described drop-bottom 1 Outboard Sections is provided with some air admission holes 6 etc., contain trying to get to the heart of a matter of carbon dish 3 and be provided with some passages 7 etc., it is characterized in that: each air admission hole 6 inner crest face such as grade of described ash container 2 some air admission holes are equipped with the dust block board 8 of the past extension that has a down dip etc., base 9 grades and the dual-side 10 of dust block board 8 grades, the inner side edges such as 11 grades and place air admission hole 6 form air inlet sealing 12 etc.

In addition, air admission hole 6 grades and corresponding dust block board 8 etc. all adopt the structure of essentially rectangular; Ash container 2 is provided with a handle 13.

In use, charcoal is placed on contains burning on carbon dish 3, and air-flow enters from air admission hole 6 grades on the ash container 2 of drop-bottom 1 outside (i.e. below), and rises out from containing passage 7 the trying to get to the heart of a matter of carbon dish 3 etc., and for the charcoal burning, to provide oxygen to carry out combustion-supporting; The part carbon ash of charcoal burning process drops in ash container 2 from containing passage 7 grades of carbon dish 3, wherein those carbon ashes that approach ash container 2 air admission hole 6 grades can drop on dust block board, then being slipped to the position away from from air admission hole 6 grades drops on ash container 2 base plates, while having accumulated more carbon ash on ash container 2 base plates, can take out ash container 2 and clear up.
