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.

The firewood and coal stove as shown in fig. 1 to 3 comprises a stove body 1, a hearth 2, an ash receiving chamber 3, a stove neck 4 and a flue 5, wherein a heat insulation layer is arranged inside the outer side of the stove body 1, the hearth 2 is provided with a fuel adding channel 7, the hearth 2 consists of a conical side wall 21 with the upper taper and the lower taper of 0.6 and a stove bridge 22, the side wall 21 is made of stainless steel, the upper part of the side wall is provided with a plurality of combustion-supporting gas holes 23, a combustion-supporting gas chamber 6 is arranged outside the side wall 21, the combustion-supporting gas chamber 6 is communicated with the hearth 2 through the combustion-supporting gas holes 23, the bottom of the combustion-supporting gas 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, namely, air can enter the ash receiving chamber 3 from the outside through an opening of the ash receiving.

The working principle is as follows: the fuel is put into the hearth 2 through the fuel adding channel 7 to be ignited, the channel door 71 is closed, the ash receiving drawer 31 is partially pulled open, so that air enters the ash receiving chamber 3, airflow moves upwards under the action of the flue 5, and then enters the hearth 2 and the combustion air chamber 6, the air in the combustion air chamber 6 is heated by the side wall 21 to reach over 500 ℃, the high-temperature air enters the hearth 2 to be beneficial to keeping the furnace temperature, and because the hearth 2 is small at the top and large at the bottom, and the high-temperature airflow in the combustion air chamber 6 enters, the airflow speed at the upper part of the hearth 2 is higher, and flame is driven to move upwards, so that the fire and the combustion efficiency are improved; when fuel needs to be added frequently (such as adding fuel of wood, straw and the like), the access door 71 needs to be opened, the ash receiving drawer 31 is closed, air enters the hearth 2 and the combustion air chamber 6 from the access door 71, smoke cannot gush out from the access door 71, the indoor environment is ensured not to be polluted by smoke, and if the ash receiving drawer 31 is not closed or the ash receiving chamber 3 is in an open structure, the smoke can gush out from the access door 71 after the access door 71 is opened; when the fire is not needed, the passage door 71 can be selectively closed and the ash receiving drawer 31 is slightly pulled open, so that a small amount of air can enter the hearth 2, the fire in the hearth 2 is ensured to be in a 'latent' state, when the fire is needed, the ash receiving drawer 31 is pulled open greatly, the fire is recovered, and the problem of fire again is avoided.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
