Description

Technical Field

[0001] The present invention relates to the technical field of heating devices, and particularly relates to an outdoor heater. Background Art

[0002] An outdoor heater is a device used for people to keep warm outdoors. Currently, there is a heater on the market that uses the combustion of biofuels to achieve the purpose of heating. When the heater is working, the biofuels can burn inside it, and the heat generated by the combustion of the biofuels can be diffused to the outside of the heater through a glass cover, so as to achieve the purpose of heating. However, when the existing heaters on the market are in use, when the biofuels inside the heater gradually decrease due to combustion, the flame generated by the combustion of the biofuels will gradually decrease and finally be lower than the height of the glass cover, which will cause the heat generated by the combustion of the biofuels to not be effectively diffused to the outside of the heater through the glass cover, and thus will affect the heating effect of the heater.

[0024] As Figures 1-6 shown, the outdoor heater of the present invention includes a base 1, a housing 2, a glass cylinder 3, and a top cover 4. The lower end of the housing 2 is fixed on the base 1. The lower end of the glass cylinder 3 is connected to the upper end of the housing 2. The lower end of the top cover 4 is connected to the upper end of the glass cylinder 3. A plurality of flue gas outlets 41 are circumferentially arranged at the upper end of the top cover 4. An inner cylinder 5 is arranged inside the middle of the housing 2. A plurality of grid plates 6 for supporting biofuel and spaced apart from top to bottom are detachably connected inside the inner cylinder 5. A wind guiding component 7 and a blower 8 are arranged inside the bottom of the housing 2. The air inlet of the wind guiding component 7 is connected to the blower 8. The wind guiding component 7 is used to guide the wind from the blower 8 into the inner cylinder 5. A temperature sensor 31 is fixed inside the upper end of the glass cylinder 3. The temperature sensor 31 is electrically connected to a controller located inside the blower 8. In addition, a plurality of support rods are fixed on the inner wall of the above-mentioned glass cylinder at circumferential intervals. The upper and lower ends of each support rod extend out of the glass cylinder. The lower end of each support rod is cooperatively inserted with the upper end of the base, and the upper end of each support rod is cooperatively inserted with the lower end of the top cover. After the upper and lower ends of the support rod are cooperatively inserted with the top cover and the housing, the firmness and reliability of the connection among the top cover, the glass cylinder, and the housing can be improved.

[0025] When using the present invention, first place the biofuel for heating into the inner cylinder, that is, place the biofuel on each grid plate (place the grid plate at the bottom of the inner cylinder into the inner cylinder, then place the biofuel on this grid plate, then place the upper grid plate into the inner cylinder, and then place the biofuel on this grid plate, and so on). Then light the biofuel at the upper end of the inner cylinder and place the inner cylinder into the housing. When the biofuel burns, the flame generated by the burning of the biofuel can be located inside the glass cylinder, and the heat generated by the flame can diffuse outward through the glass cylinder to achieve the purpose of heating. At the same time, the blower can work under the control of the controller inside it, and the air guiding component can guide the air from the blower into the inner cylinder to promote the burning of the biofuel; during the burning process of the biofuel, the temperature sensor can monitor the temperature inside the upper end of the glass cylinder in real time. When the biofuel in the inner cylinder gradually decreases due to burning, the flame generated by the burning of the biofuel will also move downward. At this time, the temperature sensor can monitor that the temperature inside the upper end of the glass cylinder also decreases. At this time, the controller can increase the rotation speed of the blower according to the temperature value monitored by the temperature sensor. When the rotation speed of the blower increases, the blower can send more air into the inner cylinder through the air guiding component to promote the burning of the biofuel, so that the flame generated by the burning of the biofuel can always be located inside the glass cylinder, that is, the flame and the glass cylinder are kept at the same height, thereby ensuring the heating effect of the heater; after the above process, under the action of the temperature sensor and the controller, the dynamic control of the rotation speed of the blower can be realized, that is, the air delivery volume of the blower can be dynamically controlled to ensure that the flame generated by the burning of the biofuel is always located inside the glass cylinder, thereby ensuring the heating effect of the heater.
