DETAILED DESCRIPTION

[0023] The following will further describe the specific implementation of the utility model in combination with the accompanying drawings of the embodiments, so that the technical solution of the utility model is easier to understand and grasp. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0024] This embodiment provides a stove, such as Figure 1-6 As shown, the furnace body 100 includes a chimney 200, a U-shaped combustion chamber 110, a fuel storage position is provided at the first end of the combustion chamber 110, and the chimney 200 is arranged corresponding to the second end of the combustion chamber 110. The first end of the combustion chamber 110 has a feeding port 120, and the end of the second end of the combustion chamber 110 is closed to ensure that smoke is discharged from the chimney 200. The fuel is placed at the fuel storage position and burned, and the smoke generated by the combustion flows from the first end of the combustion chamber 110 to the second end, and is discharged from the chimney 200. The heat carried by the smoke is transferred to the furnace body 100 during the flow in the combustion chamber 110, and the furnace body 100 is heated to heat the air outside the furnace body 100, thereby playing a heating role. The U-shaped combustion chamber 110 extends the length of the combustion chamber 110 without increasing the length of the stove, thereby increasing the residence time of the flue gas carrying heat in the combustion chamber 110, so that the heat can be more fully transferred to the stove body 100, thereby improving the heating effect of the stove. The stove body 100 includes an upper body and a lower body at the upper end. The upper body can be Figure 1 , 2 The upper body and the lower body may also be one piece. Figure 3-5 The split parts shown are fixedly connected.

[0025] like Figure 1 , 4As shown, the furnace body 100 includes a platen 130, and the platen 130 constitutes the top wall of the combustion chamber 110. In this way, the heat in the combustion chamber 110 can be directly transferred to the platen 130, which is convenient for increasing the heat of the platen 130, so that the platen 130 can be used to heat a kettle or food, or keep the food warm.

[0026] like Figure 1 , 4 As shown, the combustion chamber 110 includes a first chamber 111, a second chamber 112 and a connecting chamber 113 connecting the first chamber 111 and the second chamber 112, thereby forming a U-shape. The lower end width of the first chamber 111 and the second chamber 112 is smaller than the upper end width. The combustion chamber 110 can directly heat a larger area of ​​the platen 130, which is beneficial to improving the heating efficiency and heating uniformity of the platen 130.

[0027] like Figure 1 , 4 As shown in Figures 5 and 6, a baking tray 300 is provided on the oven body 100. The baking tray 300 can be pushed and pulled on the oven body 100. The baking tray 300 can be pulled out to add food, and the baking tray 300 can be dragged into the oven body 100, so that the oven body 100 can heat the food on the baking tray 300. The opposite side walls of the first chamber 111 and the second chamber 112 are inclined to form a triangular or trapezoidal heat radiation cavity 140. The heat radiation cavity 140 is connected to the inner cavity of the baking tray 300, so that the side walls of the first chamber 111 and the second chamber 112 radiate heat to the baking tray 300. The side wall temperature of the first chamber 111 is higher than the side wall temperature of the second chamber 112. The radiated heat of the two side walls is mixed in the heat radiation cavity 140 and further heats the food on the baking tray 300, which is conducive to improving the uniformity of food heating.

[0028] like Figure 1 , 5 As shown, the bottom wall of the connecting cavity 113 is lower than the bottom walls of the first cavity 111 and the second cavity 112, and the bottom wall of the connecting cavity 113 is located above the baking tray 300. The bottom wall of the connecting cavity 113 is close to the baking tray 300, so that the food in the corresponding area of ​​the baking tray 300 can be heated more efficiently. Food that is not easy to cook can be placed in the baking tray 300 area corresponding to the bottom wall of the connecting cavity 113. The connecting cavity 113 is located at the end of the furnace body 100 and is open to the outside. A transparent baffle 114 is provided on the furnace body 100 to block the connecting cavity 113. The larger connecting cavity 113 is convenient for users to observe the flame condition in the combustion cavity 110.

[0029] like Figure 2 , 3As shown, the combustion chamber 110 has an ash outlet on the bottom wall where the fuel storage position is located, and a movable ash box 400 is provided directly below the ash outlet. An ash tray 410 located lower than the ash box 400 is provided on the furnace body 100, and an ash channel 150 is provided on the side wall or bottom wall of the chamber where the ash box 400 is located, so that when the ash box 400 is partially or completely pulled out of the chamber where it is located, the ashes dropped from the ash outlet can enter the ash tray 410 through the ash channel 150. The ash box 400 can be completely embedded in the furnace body 100, so that the ashes dropped by the fuel combustion can all fall into the ash box 400, or the ash box 400 can be partially pulled out, so that the fuel storage position is connected to the outside through the ash outlet. By controlling the different pulling degrees of the ash box 400, the air intake of the fuel storage position can be adjusted, thereby adjusting the size of the flame. At this time, the ashes can partially enter the ash tray 410 through the ash leakage channel.

[0030] like Figure 1-3 As shown, the furnace body 100 is provided with a feeding pipe 500 above the fuel storage position, and a cover plate 510, a stove rack or a funnel 520 are provided on the top of the feeding pipe 500. The feeding pipe 500 can increase the distance from the feeding port to the fuel storage position, reduce the risk of flame scalding the user during fueling, and when fueling, a funnel 520 can be placed on the upper end of the feeding pipe 500 to facilitate the feeding operation. In addition, a cover plate 510 can be placed on the upper end of the feeding pipe 500 to prevent smoke from being discharged directly from the feeding pipe 500, and a stove rack can be placed on the upper end of the feeding pipe 500, and pots can be placed on the stove rack to perform cooking operations.

[0031] like Figure 3 As shown, the fuel storage position is provided with a removable combustion frame 600, and the bottom of the combustion frame 600 has an ignition cavity 610. After the combustion frame 600 is taken out from the furnace body 100, fuel is placed in the combustion frame 600, and then an igniter with alcohol or other items is placed in the ignition cavity 610. By igniting the igniter, the fuel in the combustion frame 600 is ignited by the igniter, so as to avoid the user holding the igniter for a long time. The removable combustion frame 600 is convenient for fuel placement and fuel ignition. After the fuel is ignited, the combustion frame 600 is placed in the fuel storage position by operating the workpiece 620. The bottom of the combustion frame 600 has an ash falling opening so that the ash in the combustion frame 600 can fall from the ash falling opening into the ash falling opening, and further fall into the ash box 400 or the ash collecting tray 410. The furnace body 100 is provided with a tool placement cavity 160 below the ash collecting tray 410, and the operating workpiece 620, the funnel 520, and the furnace rack can all be placed in the tool placement cavity 160 for temporary storage.

[0032] like Figure 2 , 6As shown, the feed port 120 is provided with an air intake baffle 700, and the air intake baffle 700 is provided with an air adjustment port 710 and an air adjustment member 720, and the air adjustment member 720 is rotatably connected relative to the air intake baffle 700 to open or close the air adjustment port 710. The air adjustment member 720 is connected to an adjustment handle 722, and the air adjustment member 720 has an air inlet 721 that can correspond to the air adjustment port 710. When the adjustment handle 722 is operated, the air inlet 721 corresponds to the air adjustment port 710, and the outside air can enter the combustion frame 600 from the air adjustment port 710 and the air inlet 721. By controlling the different degrees of correspondence between the air inlet 721 and the air adjustment port 710, the air intake speed of the air inlet 721 and the air adjustment port 710 is controlled, thereby controlling the fire in the combustion frame 600. When the air inlet 721 is completely staggered from the air adjustment port 710, the air adjustment port 710 is closed. The user can also control the air intake speed by moving the entire air intake baffle 700 .

[0033] The stove is independent and movable, and can be used for indoor and outdoor fire, heating, frying, boiling and barbecue. The flame can form a dragon-like fire in the U-shaped combustion chamber. The transparent baffle is made of 1000-degree high-temperature resistant glass. It saves 90% of wood compared to traditional wood-burning stoves and saves about 70% of costs compared to general electric heating. It is suitable for homestays and home heating, and can be used as a heat source for cooking. It is beautiful, energy-saving and environmentally friendly.
