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, a firewood and coal stove with a 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, a combustion-supporting air chamber 6 and a water tank 8 are arranged outside the side wall 21, 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, namely, air can enter the ash receiving chamber 3 from the outside through an opening of the ash receiving drawer 31, the fuel adding channel 7 is provided with a channel door 71 which can be opened, A water outlet pipe 82, a steam pipe 83 and a safety relief valve, and an insulating layer is arranged on the outer side of the water tank 8.

The working principle is as follows: when the water tank is used, water is added into the water tank 8 through the water inlet pipe 81, fuel is placed 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-supporting air chamber 6, the air in the combustion-supporting air chamber 6 is heated by the side wall 21 to reach over 500 ℃, the high-temperature air is used for heating the water tank 8, the high-temperature air enters the hearth 2 to be beneficial to keeping the temperature of the furnace, and due to the fact that the hearth 2 is small in top and large in bottom and the high-temperature airflow in the combustion-supporting air chamber 6 enters, the airflow speed at the upper part; 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 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 fire is needed, the ash receiving drawer 31 is pulled open greatly, the fire is recovered, and the problem of fire again is avoided; boiled water and steam in the water tank 8 are discharged for use through the water outlet pipe 82 and the steam pipe 83, respectively.
