[0027] Specifically, the furnace body 1 includes side panels 11 at left and right ends, and the door frame 24 is hingedly arranged between the two side panels 11 .

[0028] Preferably, the door panel 21 is provided with first bending portions 211 at both left and right ends, and the raised plate 210 is arranged at the upper end of the first bending portion 211 .

[0029] When the raised plate 210 is locked with the limiting plate 12, the contact surface of the raised plate 210 and the limiting plate 12 is located between the furnace body 1 and the door panel 21, and the contact surface of the raised plate 210 and the limiting plate 12 is a plane, and the position where the raised plate 210 does not contact the limiting plate 12 is an arc, and when the door panel 21 rotates around the hinge point between the door panel 21 and the door frame 24, the raised plate 210 does not contact the furnace body 1 at all times. In this application, the raised plate 210 is fan-shaped, and can also be a polygon in addition to the fan shape. , triangle, etc. When the door panel 21 rotates around the hinge point between the door panel 21 and the door frame 24, the raised plate 210 will not touch the shape of the furnace body 1. In addition, the furnace body 1, the door panel 21 and the door frame 24 all have openings, and the opening on the door frame 24 is used to install the glass. When locked, the hinge point between the door panel 21 and the door frame 24 is located above the hinge point between the side panel 11 and the door frame 24, and the side panel 11 has a matching hole 110 for allowing the hinge point of the door panel 21 and the door frame 24 to be placed.

[0030] The door frame 24 is provided with a mounting hole 241 for mounting the optical observation window, and the door panel 21 is also provided with a through hole 23 corresponding to the mounting hole 241. The observation window in the present application is made of glass, and can also be made of other high-temperature resistant transparent materials.

[0031] At least one side of the through hole 23 has a bent reinforcing plate 231. In the present application, bent reinforcing plates 231 are arranged on the upper and lower sides of the through hole 23, thereby improving the structural strength of the door panel 21. Reinforcing plates 231 can also be arranged on all sides of the through hole 23, thereby further improving the structural strength of the door panel.

[0032] An asbestos strip 242 is installed at the edge of the installation hole 241. The asbestos strip 242 plays a role in buffering and thermal expansion and contraction at high and low temperatures, thereby preventing the glass from being crushed.

[0033] A second bending portion 212 for installing the handle 22 is provided at the bottom of the door panel 21. The second bending portion 212 can also play a role in further improving the structural strength of the door panel 21. The handle 22 is installed on the door panel 21.

[0035] When opening the door, the first handle 22 is pulled to first rotate the door panel 21 around the hinge point between the door panel 21 and the door frame 24. When the door panel 21 is pulled to rotate and the raised plate 210 is disengaged from the placement groove 111, the first handle 22 is pulled horizontally to move to the side away from the furnace body 1, thereby causing the door panel 21 and the door frame 24 to swing around the hinge point between the door frame 24 and the side panel 11, thereby realizing the door opening function. The door opening assembly of the present application is movably installed on the front side of the furnace body 1, and the front side end face area of ​​the furnace body 1 is larger than the side panel 11 area. Therefore, installing the door opening assembly on the front side of the furnace body 1 has a larger opening surface, and more firewood can be added at one time, thereby making it more convenient to add firewood.

[0036] When closing the door, hold the first handle 22 to rotate the door panel 21 and the door frame 24 around the hinge point between the door frame 24 and the side panel 11 until the raised plate 210 moves to the lower end of the limit plate 12. At this time, let go. Through the gravity of the door panel 21, the door panel 21 will swing downward around the hinge point between the door panel 21 and the door frame 24, and make the raised plate 210 swing into the placement groove 111, so that the door panel 21 can be automatically closed to achieve the function of closing and locking the door.
