Description

Technical Field

[0001] This invention relates to the field of fireplaces, specifically to a fireplace that is easy to clean. Background Technology

[0002] Fireplaces are mostly used for indoor heating or decoration in homes. Fireplaces come in various structures, including coal-fired, gas-fired, and wood-fired types. Among them, the wood-fired type is the most economical and widely used. Its principle is that the heat generated by the burning of wood inside the fireplace heats the local air, and the irregular airflow in the room achieves whole-house heating. Wood-fired fireplaces are prone to producing fly ash and ashes, which adhere to the inside of the fireplace and affect its heating effect.

[0003] Patent document CN114440263A discloses a sustainable heating fireplace, including a fireplace body and a door panel. The fireplace body has a combustion chamber, and the door panel is rotatably connected to the fireplace body. It also includes an automatic feeding mechanism and an automatic ignition device. The combustion chamber contains a combustion box with multiple sieve holes on its bottom wall for the ash from burned wood chips to pass through. The automatic feeding mechanism automatically loads the wood chips needed for combustion into the combustion box, and the automatic ignition device ignites the wood chips in the combustion box. The operator uses the automatic feeding mechanism to automatically add wood chips to the combustion box, and then uses the automatic ignition device to ignite the newly added wood chips. The burned wood chips turn into ash and fall through the sieve holes. This process repeats, allowing the fireplace to continuously heat the room. The operator only needs to open the door panel periodically to clean the combustion chamber, reducing the operator's workload.

[0004] However, cleaning the interior still requires opening the fireplace, making it impossible to clean while the fireplace is in use. Summary of the Invention

[0005] The purpose of this invention is to provide a fireplace that is easy to clean, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An easy-to-clean fireplace includes a firebox, an ash chamber connected to the bottom of the firebox, a smoke exhaust port at the top, a circular cross-section of the firebox, an insulation layer fixed to the outside of the firebox, a heat conduction port on the side of the insulation layer, a heat conduction cylinder rotatably connected to the insulation layer, a cleaning rod connected to the insulation layer and attached to the inside of the heat conduction cylinder, the heat conduction cylinder being driven by a cleaning gear, the cleaning gear being rotatably connected to one side of the heat conduction port, and an ash cleaning plate being provided inside the ash chamber.

[0008] Preferably, the outer ends of the heat-conducting cylinder are respectively fixed with support gear rings, which mesh with the cleaning wheel. The two cleaning gears are fixedly connected by a shaft, which passes through the insulation layer and is fixedly connected to the throttle.

[0009] Preferably, a grate is provided at the bottom of the heat-conducting cylinder, the grate is composed of spaced arc plates with the same curvature as the heat-conducting cylinder, and a through hole communicating with the flue gas outlet is provided at the top of the heat-conducting cylinder.

The connecting shaft is rotatably connected inside the insulation layer and is connected to the insulation layer via a torsion spring.

[0011] Preferably, the cleaning rod has two tapered ends that are attached to the inner side of the heat-conducting cylinder, and the two ends of the cleaning rod are fixed to the inner sides of the insulation layer.

[0012] Preferably, the cross-section of the ash chamber is an arc surface concentric with the heat-conducting cylinder, the ash cleaning plate is attached to the inner wall of the ash chamber, the ash cleaning plate is fixedly connected to the push plate, the push plate is threadedly connected to the push screw, the push screw passes through one side of the insulation layer and is connected to the push knob, and the ash discharge port is provided on the other side of the ash chamber.

Detailed Implementation

[0028] Example 1

[0029] like Figure 1-7A fireplace that is easy to clean includes a firebox, with an ash chamber 11 connected to the bottom and a smoke vent 63 at the top. The firebox has a circular cross-section. An insulation layer 1 is fixed to the outside of the firebox, and a heat conduction port is provided on the side of the insulation layer 1. A heat conduction cylinder is rotatably connected to the insulation layer 1. A cleaning rod 7 connected to the insulation layer 1 is attached to the inside of the heat conduction cylinder. The heat conduction cylinder is driven by a cleaning gear 42, which is rotatably connected to one side of the heat conduction port. A cleaning plate 8 is provided inside the ash chamber 11. Supporting toothed rings 62 are fixed to both ends of the outside of the heat conduction cylinder. The supporting toothed rings 62 are connected to the cleaning plate 8. The cleaning gears 42 are meshed and fixedly connected by a shaft 41, which passes through the insulation layer 1 and is fixedly connected to the throttle. A grate 61 is provided at the bottom of the heat-conducting cylinder. The grate 61 is composed of spaced arc plates with the same curvature as the heat-conducting cylinder. A through hole communicating with the exhaust port 63 is provided at the top of the heat-conducting cylinder. A cleaning block 91 is rotatably connected inside the insulation layer 1 below the grate 61. The side of the cleaning block 91 is arc-shaped. The cleaning block 91 is fixed on the connecting shaft 9. The connecting shaft 9 is rotatably connected inside the insulation layer 1. The connecting shaft 9 is connected to the insulation layer 1 by a torsion spring 92.

[0030] The front side of the insulation layer 1 is connected to a closed door via a hinge. The closed door connects to the interior of the furnace and is used for adding fuel. For lighting purposes, a sealed door made of explosion-proof glass can be used. Since the closed door is not shown in the figure, the insulation layer 1 is fixed against the wall, and the exhaust pipe 5 extends to the outside. The rear side of the insulation layer 1 extends out of the wall. Fuel is added through the closed door into the heat-conducting cylinder inside the furnace cavity. A grate 61 is set at the bottom of the heat-conducting cylinder for fuel slag to fall into the ash chamber 11. The rear side of the furnace extends to the outside of the wall. The generated flue gas is discharged through the exhaust pipe 5. As the airflow in the room flows through the heat-conducting ports on both sides of the insulation layer 1, it exchanges heat with the heat-conducting cylinder to achieve indoor heating.

[0031] Ash produced during fuel combustion inside the heat-conducting cylinder may adhere to the inner wall of the cylinder, affecting its heat exchange rate and reducing the heating capacity of the fireplace. Therefore, a cleaning rod 7 is fixedly connected inside the furnace cavity. The two ends of the cleaning rod 7 are fixed to the front and rear sides of the furnace cavity, respectively. The cleaning rod 7 is in contact with the inner wall of the heat-conducting cylinder. By rotating the cleaning knob 4, the shaft 41 is rotated, and the cleaning gear 42 fixedly connected to the shaft 41 rotates. The cleaning gear 42 can make the heat-conducting cylinder rotate, and the heat-conducting cylinder slides relative to the cleaning rod 7. The cleaning rod 7 can scrape off the ash adhering to the inner wall of the heat-conducting cylinder. Afterward, the heat-conducting cylinder is rotated to its reset position, so that the scraped ash falls from the grate 61 into the ash chamber 11. Therefore, the inner wall of the heat-conducting cylinder can be cleaned without opening the furnace cavity, preventing fly ash generated during the cleaning process from affecting the indoor air quality. At the same time, it can be cleaned in time while the fuel is burning, ensuring the heat exchange efficiency of the heat-conducting cylinder.

[0032] A connecting shaft 9 is rotatably installed at the lower part of the grate 61. A cleaning block 91 extending into the grate 61 is fixed on the connecting shaft 9. During the rotation of the heat conduction cylinder, the cleaning block 91 slides in the grate 61 to prevent fuel from getting stuck in the grate 61 and causing poor ash discharge. The two ends of the cleaning block 91 are connected to the ash chamber 11 through torsion springs 92, which allows the cleaning block 91 to rotate with the rotation of the heat conduction cylinder. During the rotation of the heat conduction cylinder, the cleaning block 91 will not get stuck in the heat conduction cylinder. After the heat conduction cylinder is reset, the cleaning block 91 is reset under the action of the torsion spring 92.

[0033] Example 2

[0034] like Figure 1-7 As shown, an easy-to-clean fireplace includes a firebox, an ash chamber 11 connected to the bottom of the firebox, a smoke exhaust port 63 at the top, a circular cross-section of the firebox, an insulation layer 1 fixed to the outside of the firebox, a heat conduction port on the side of the insulation layer 1, a heat conduction cylinder rotatably connected to the insulation layer 1, a cleaning rod 7 connected to the insulation layer 1 and attached to the inside of the heat conduction cylinder, the heat conduction cylinder being driven by a cleaning gear 42, the cleaning gear 42 being rotatably connected to one side of the heat conduction port, and an ash cleaning plate 8 provided inside the ash chamber 11.

[0035] The cleaning rod 7 has two tapered ends that are attached to the inside of the heat-conducting cylinder. The cleaning rod 7 is fixed to the inside of the insulation layer 1 on both sides. The cleaning rod has a tapered cross-section at both ends. When the heat-conducting cylinder slides relative to the cleaning rod, it reduces the resistance between the cleaning rod and the heat-conducting cylinder, so that the heat-conducting cylinder can rotate smoothly and clean the ash on the inner wall of the heat-conducting cylinder.

[0036] The ash chamber 11 has a cross-section that is concentric with the heat-conducting cylinder. A cleaning plate 8 is attached to the inner wall of the ash chamber 11. The cleaning plate 8 is fixedly connected to a pusher plate, which is threadedly connected to a pusher screw 31. The pusher screw 31 passes through the insulation layer 1 and is connected to a pusher knob 3 on one side. An ash discharge port is provided on the other side of the ash chamber 11. A sealing plate is inserted into the ash discharge port, and the upper part of the sealing plate is rotatably connected to the ash discharge port. During cleaning, rotating the pusher knob 3 causes the pusher screw 31 to rotate, and the pusher plate threadedly connected to the pusher screw 31... Sliding inside the ash chamber 11, the ash falling into the ash chamber 11 can be discharged. The sealing plate 12 is connected to the rear side of the insulation layer 1 by a hinge. Under normal conditions, the sealing plate 12 hangs down naturally under the action of gravity, blocking the rear side of the ash chamber 11 and reducing the heat loss of the heat conduction cylinder. When the pusher plate pushes the ash, the sealing plate 12 opens under the pushing force of the ash, allowing the ash in the ash chamber 11 to be discharged. After the ash is discharged, the sealing plate 12 can re-close the ash chamber 11 under the action of gravity.

[0037] Protective baffles 2 are installed on both sides of the furnace outside the heat conduction port. The protective baffles 2 have a mesh structure and are rotatably connected to the flow aid fan 6 inside the protective baffles 2. A sealing door is rotatably connected to one end of the furnace, and a flow guide hole is set at the other end of the furnace. The flow guide hole is connected to the flow aid fan. The protective baffles 2 are used to seal the heat conduction port to prevent objects from directly contacting the heat conduction cylinder at the heat conduction port, which could cause burns or cause indoor items to burn. The flow aid fan 6 is set inside the protective baffles 2 to accelerate the local airflow velocity in the room and improve the heat exchange rate. A flow aid fan is set at the rear of the furnace and is connected to the furnace cavity through a one-way valve. When the fuel combustion reaction is small, fresh outdoor air can be introduced for combustion aid.
