Description

It is applicable to the firewood and coal dual-purpose cooking stove of large scale pan

Technical field

The present invention relates to a kind of stove, particularly to a kind of firewood and coal dual-purpose cooking stove being applicable to large scale pan.

Background technology

In current coal stove, stove upper end is provided with the table for supporting cooker, arranges at the middle part of table Have the crater corresponding with burner hearth, by the fuel such as fire coal is added in stove, fuel after the stove chamber inner combustion of stove, steam Rise through the crater being arranged on stove upper end, and then the cooker that heating is placed on stove.In use, cooker is placed on On table, crater is covered by cooker, so that, when the overall dimensions of cooker is less than crater, owing to can not get table Support, and cause using；And for the bigger cooker of overall dimensions, owing to crater is the least with cooker, Can heat the local of cooker, the efficiency of heating surface is low, and firing rate is slow.

It is to say, in current stove, the cooker size being suitable for generally is determined by the size of crater, for chi Very little bigger pan, is merely able to select the larger-size stove of burner, so, causes current stove poor universality, not The multipurpose demand of user can be met；

On the other hand, for fuel, the most fierce during the biomass fuel combustion such as bavin, it is possible to quickly heating cooker, and Fire coal has good ignition temperature, it is possible to steady and lasting heats cooker, so, at current kitchen knot In structure, particularly rural kitchen, it is common that be simultaneously provided with coal-fired stove and log cooking stove, in daily life, generally use combustion The coal stove less cooker of heating, carries out hot water or cooks, using the cooker that log range burner is bigger, carry out cooking or its He cooks.Being provided separately of bavin cooking stove and coal cooking stove, not only needs to occupy bigger kitchen space, and, too increase For construction cost.So, how coal cooking stove and bavin cooking stove organically to be combined is to need problem to be solved at present badly.
