Description

Technical Field

[0001] The utility model relates to the technical field of ovens, in particular to a gas-fired and particle-fired oven. Background Art

[0002] The essence of environmentally friendly biomass pellet fuel is the direct combustion of biomass energy, which is the processing and utilization of biomass. Direct combustion methods can be divided into four types: stove combustion, boiler combustion, garbage combustion and solid fuel combustion. Among them, solid fuel combustion is a newly promoted technology. It solidifies the biomass into a shape and then uses traditional coal-fired equipment. Its advantage is that it makes full use of biomass energy to replace coal, reduces CO2 and SO2 emissions, is beneficial to environmental protection and controls greenhouse gas emissions, slows down climate change, and reduces the occurrence of natural disasters.

[0003] A gasification stove that uses environmentally friendly biomass pellet fuel. All biomass pellet stoves currently sold on the market require electricity to drive, use a straight-cylinder combustion method, and are equipped with a microcomputer controller device such as a feeding reducer, a fan, and an electronic igniter. The combustion stove using electrical equipment has many after-sales services and is relatively complicated for users to use. It is difficult for many users to operate and use it. The use of a fan increases the fuel cost, and there is a lot of smoke and ash, and dust splashes at intersections, causing great problems in indoor cleaning. The installation of electrical equipment consumes more electricity, and it is basically unusable during a power outage. After a period of time, the aging and replacement of electrical components increases maintenance costs.

[0004] The existing patent (publication number: CN219222391U) discloses an environmentally friendly biomass molded particle fuel carbonization barbecue stove, which includes a barbecue stove fixing frame, the top of which is fixedly connected to an ash collecting furnace, the top of which is fixedly connected to a first combustion furnace, the inner side of the first combustion furnace is movably connected to a U-shaped furnace bridge, the top of the first combustion furnace is fixedly connected to a feed square tube, and the top of the first combustion furnace is fixedly connected to a second combustion furnace. The biomass particle fuel is burned in the U-shaped furnace bridge, so that the fuel can be suspended and burned, and the fuel can make full use of the incoming oxygen so that the fuel can achieve a controllable combustion effect. The combustion is completely driven by natural wind energy, no electricity is required, and the relative energy saving is more than 15%. The user operation is simple, which is basically equivalent to the original firewood stove, and uses a U-shaped gasification combustion method, does not use any electrical equipment, is environmentally friendly and hygienic, and has higher combustion efficiency.

[0005] However, the above technical solution still has certain defects. During use, the above-mentioned stove can only use a single pellet fuel. If the pellet fuel is used up in actual use, the stove cannot be used any further, which requires the user to remember to keep enough pellet fuel at home, resulting in poor adaptability of the stove and certain inconveniences during use. Therefore, a gas-pellet dual-purpose stove is proposed. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0027] The following describes an embodiment of the utility model based on its overall structure.

[0028] A gas-fired and pellet-fired dual-purpose oven, as shown in the figure, comprises an oven body 1, the oven body 1 comprises an outer shell 101, an inner liner 102 is fixedly connected to the inner wall of the outer shell 101, the top of the inner liner 102 is connected to a chimney 103 extending to the outside of the outer shell 101, the side wall of the outer shell 101 is slidably connected to a fuel holding frame 104, the side wall of the outer shell 101 is slidably connected to a feeding port 105 located above the fuel holding frame 104, the top of the feeding port 105 is hinged with a flip cover 106, a thermometer 107 is fixedly installed on the side wall of the outer shell 101, a gas stove head 108 located next to the thermometer 107 is fixedly connected to the side wall of the outer shell 101, a handle is fixedly connected to the top of the flip cover 106, and the outer wall of the handle is fixedly sleeved with an anti-scalding sheath.

[0029] By flipping over the flap 106, the pellet fuel is poured into the charging port 105, so that the pellet fuel falls into the fuel holding frame 104 along the charging port 105, and then the pellet fuel is ignited, and the flap 106 is flipped over in the opposite direction, and then the oven can be used. When it is necessary to clean the residue left after the burning of the pellet fuel, the fuel holding frame 104 is pulled out of the outer shell 101, and then the residue after the burning of the pellet fuel in the fuel holding frame 104 is poured out, and then the fuel holding frame 104 is pushed back into the outer shell 101 to complete the cleaning, and the gas pipeline is connected to the gas stove head 108, and gas is used for combustion to replace the fuel pellets.

[0030] Please refer to the figure in particular. The top of the housing 101 is fixedly connected with an air supply mechanism 2. The air supply mechanism 2 includes a heating chamber 201. The inner wall of the heating chamber 201 is provided with an air duct 202. The side wall of the heating chamber 201 is fixedly installed with an air intake fan 203. The side wall of the heating chamber 201 is connected with an air outlet pipe 204. The end of the air outlet pipe 204 is connected with a bellows 205. The top of the bellows 205 is fixedly connected with a rotating rod 206. The rotating rod 206 is rotatably connected to the top of the air outlet pipe 204. The end of the rotating rod 206 away from the bellows 205 is fixedly connected to a limiting plate 207, and a limiting groove 208 is provided at the top of the limiting plate 207. The top of the air outlet pipe 204 is fixedly connected to a guide rod 209, and a limiting rod 210 is slidably sleeved on the outer wall of the guide rod 209. The end of the limiting rod 210 is slidably connected to the inside of the limiting groove 208. The side wall of the limiting rod 210 is fixedly connected to a spring sheet 211, and the end of the spring sheet 211 is fixedly connected to the side wall of the guide rod 209.

[0031] The airflow is pushed into the air duct 202 by the air intake fan 203. The air duct 202 is bent back and forth, so that the air can be fully heated in the process of passing through the air duct 202. Then, the hot air is discharged from the bellows 205 through the air outlet pipe 204, so that the heat can be better diffused to other locations in the house. By pushing the limit rod 210, the limit rod 210 slides on the outer wall of the guide rod 209, so that the limit rod 210 compresses the spring sheet 211, so that the end of the limit rod 210 slides out from the limit groove 208, and then pushes the bellows 205. The bellows 205 is bent so that the rotating rod 206 is rotated, thereby aligning the corresponding groove on the limiting groove 208 with the limiting rod 210. Then the limiting rod 210 is released, so that the spring sheet 211 rebounds. At this time, the spring sheet 211 pushes the limiting rod 210 to slide in the opposite direction on the outer wall of the guide rod 209, and then the end of the limiting pin slides into the corresponding groove on the limiting groove 208, so that the rotating rod 206 is blocked by the limiting rod 210 and cannot rotate. Therefore, the bending angle of the bellows 205 is fixed at this time, so that the flow direction of the hot air flow can be controlled manually.

[0032] When in use, the flap 106 is flipped open, and then pellet fuel is put into the fuel holding frame 104 through the charging port 105, so that the oven can provide heat by burning the pellet fuel. The gas pipeline can also be connected to the gas stove head 108, so that the gas can be burned and heated inside the oven, making the oven more flexible and changeable during use, improving the adaptability and convenience of the oven, and the parts not involved in the device are the same as the existing technology or can be implemented by the existing technology.
