Description

Firewood and coal dual-purpose cooking stove suitable for large scale cookware

Technical field

The present invention relates to a kind of stove, in particular to a kind of firewood and coal dual-purpose cooking stove suitable for large scale cookware.

Background technique

In current coal stove, stove upper end is provided with the table for being used to support cooker, is arranged at the middle part of table There is crater corresponding with burner hearth, by the way that the fuel such as fire coal are added in stove, fuel is after the furnace chamber inner combustion of stove, hot gas The crater that stove upper end is set is risen through, and then heats the cooker being placed on stove.When in use, cooker is placed on On table, cooker covers crater, so that, when the outer dimension of cooker is less than crater, due to cannot get table Support, and cause to use；And cooker biggish for outer dimension, since crater is opposite smaller with cooker, only The part of cooker can be heated, heating efficiency is low, and heating speed is slow.

That is, the cooker size being applicable in usually is determined by the size of crater, for ruler in current stove Very little biggish cookware is merely able to the selection larger-size stove of crater, in this way, leading to current stove poor universality, not It is able to satisfy the multipurpose demand of user；

On the other hand, for fuel, bavin etc. is more fierce when burning biomass fuel, can quickly heat and cook a meal Tool, and it is coal-fired there is good ignition temperature, can it is steady and it is lasting cooker is heated, so, current In the structure of kitchen, especially rural kitchen is usually provided with coal-fired stove and firewood cooking stove simultaneously, in daily life, usually Lesser cooker is heated using coal-fired stove, carry out hot water or is cooked, using the biggish cooker of firewood range burner, is fried Dish or other culinary arts.Being provided separately for bavin cooking stove and coal cooking stove, not only needs to occupy biggish kitchen space, moreover, Increase for construction cost.So how organically to combine coal cooking stove and bavin cooking stove is that there is an urgent need for solutions at present The problem of.
