Description

Technical Field

[0001] This utility model relates to the field of electric fireplace technology, and in particular to an electric fireplace with adjustable size. Background Technology

[0002] Electric fireplaces mainly generate heat through heating elements such as resistance wires, carbon fiber heating tubes, and halogen tubes. When current passes through these heating elements, electrical energy is converted into heat energy, which raises the temperature of the heating elements. Then, the heat is dissipated into the surrounding space through thermal radiation and thermal convection, thereby achieving the purpose of heating.

[0003] Most electric fireplaces on the market are freestanding, with independent shells and bases, allowing them to be placed anywhere in the living room, bedroom, or other rooms. They are easy to move, require no complicated installation, and are suitable for already decorated rooms, with their placement adjustable as needed. However, electric fireplaces are often limited by fixed dimensions, making it difficult to adapt to specific space requirements during installation. They are either too large, taking up too much space, or too small, failing to achieve the desired decorative and heating effects. Existing technology uses modular splicing designs for electric fireplaces, allowing users to freely choose the number of splicing modules based on the size of their walls and the layout of their rooms, thus precisely customizing the size to suit the space. However, for modular splicing electric fireplaces, gaps will appear at the splicing points. Even if the splicing is made as tightly as possible during installation, due to factors such as thermal expansion and contraction of materials, these gaps will gradually widen or become more noticeable during use, affecting the overall aesthetics of the electric fireplace. Utility Model Content

A rotating shaft 203 is rotatably connected to an adjacent side of the inner wall of the connecting block 202. A gear 204 is rotatably connected to the middle of the outer wall of the rotating shaft 203. The rotating shaft 203 is used to rotate the gear 204. A rack 205 is meshed with the top wall of the gear 204, causing the gear 204 to rotate. The rack 205 is fixedly connected to the inner wall of the square groove 14. On the rear side of the top wall, the bottom wall of gear 204 is meshed with rack 3 206. Gear 204 is used to move rack 3 206. A fan 207 is installed on the bottom wall of rack 3 206. The fan 207 enables hot air to circulate better in the room and improves heating uniformity. A slide rail 208 is slidably connected to the bottom wall of the fan 207. The slide rail 208 is used to slide the fan 207. The slide rail 208 is fixedly connected to the rear side of the inner bottom wall of the square groove 14. Multiple resistance wires 22 are installed at equal intervals on the upper and lower sides of the inner wall of the square groove 14. The heat generated by the resistance wires 22 will directly radiate to the surrounding space, raising the air temperature around the electric fireplace.

[0034] Specifically, the electric push rod 201 inside the square groove 14 is activated, and the output end of the electric push rod 201 drives the gear 204 inside the connecting block 202 to rotate on the rack 205. Since the rack 205 is fixed to the inner wall of the square groove 14, the fan 207 on the bottom wall of the bottom rack 206 driven by the gear 204 moves a greater distance in the slide rail 208, so that the air inside the square groove 14 is constantly circulating, so that the hot air can circulate better in the room, improve the heating uniformity, and the heat generated by the resistance wire 22 will directly radiate to the surrounding space, so that the air temperature around the electric fireplace will rise.

[0035] Reference Figure 1 A controller 15 is installed on the lower right side of the front side of the outer wall of the furnace body 1. The controller 15 automatically adjusts the heating power of the resistance wire 22 according to the difference between the actual indoor temperature and the set temperature to keep the indoor temperature stable near the set value. Multiple buttons 16 are installed at equal intervals on the lower right side of the outer wall of the controller 15. The buttons 16 are used to adjust the parameters of the controller 15. An air outlet 19 is opened on the lower left side of the front side of the outer wall of the furnace body 1. A switch 20 is installed on the lower right side of the front side of the outer wall of the furnace body 1. The switch 20 is used to turn the power of the furnace body 1 on and off.

[0036] Specifically, the controller 15 will automatically adjust the heating power of the resistance wire 22 according to the difference between the actual indoor temperature and the set temperature, so as to keep the indoor temperature stable near the set value. The button 16 is used to adjust the parameters of the controller 15, and the switch 20 is used to turn the power supply of the furnace body 1 on and off.

[0037] Working principle: First, insert the fixing block 12 of furnace body 2 3 into the sliding groove 2 11 of furnace body 1. Then, rotate the knob 4 on the back of furnace body 1. The knob 4 drives the rotating shaft 1 5 to rotate. The rotating shaft 1 5 drives the gear 1 7 to rotate in the circular groove 6. The gear 1 7 drives the locking block 9 on the outer wall of the rack 1 8 on the left to slide in the sliding groove 10. As the rack 1 8 moves downward, the locking block 9 will engage with the slot 13 on the fixing block 12, so that furnace body 1 1 and furnace body 2 3 are spliced ​​together.

[0038] The electric push rod 201 inside the square groove 14 is activated. The output end of the electric push rod 201 drives the gear 204 inside the connecting block 202 to rotate on the rack 205. Since the rack 205 is fixed to the inner wall of the square groove 14, the fan 207 on the bottom wall of the bottom rack 206 driven by the gear 204 moves a farther distance in the slide rail 208, so that the air inside the square groove 14 is constantly circulating, so that the hot air can circulate better in the room and improve the heating uniformity.
