Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1 to 3, the firewood and coal stove with a steam hot water tank comprises a stove body 1, a hearth 2, an ash receiving chamber 3, a stove neck 4 and a flue 5, wherein the hearth 2 is provided with a fuel adding channel 7, the hearth 2 is composed of a conical side wall 21 with a taper of 0.6 and a stove bridge 22, the side wall 21 is made of stainless steel, the upper part is provided with a plurality of combustion-supporting gas holes 23, the side wall 21 is externally provided with a combustion-supporting air chamber 6 and a steam generating water tank 8, the combustion-supporting air chamber 6 is communicated with the hearth 2 through the combustion-supporting gas holes 23, the bottom of the combustion-supporting air chamber 6 is communicated with the ash receiving chamber 3, the side surface and the bottom of the ash receiving chamber 3 are closed, the ash receiving chamber 3 is provided with an ash receiving drawer 31, when the ash receiving drawer 31 is pulled open, the ash receiving chamber 3 is communicated with the outside, namely, air can enter the ash receiving chamber 3 from the outside through an opening of the ash receiving drawer, the fuel adding channel 7 is provided with a, The steam heating water tank 9 is connected with the steam pipe 83, the steam pipe 83 is provided with a second water inlet pipe 91 and a second water outlet pipe 92, and the outer sides of the steam generating water tank 8 and the steam heating water tank 9 are both provided with heat insulation layers.
