Description

Technical Field

[0001] This application relates to the field of residential heating technology, and in particular to a clean heating stove. Background Technology

[0002] As people's living standards improve, outdoor activities and winter heating methods are becoming increasingly diverse. As a portable and practical heating and cooking tool, fireplaces are gaining popularity among consumers. Currently, there are many types of fireplaces on the market, which can be categorized by energy type, such as biomass fuel type, gas type, and electric heating type.

[0003] Common biomass fuel stoves can burn firewood or biomass pellets. They typically consist of a furnace core, an outer shell, and an ash collection box. The furnace core is installed inside the outer shell and has an ash outlet at the bottom. The ash collection box is slidably positioned below the outer shell and corresponds to the ash outlet. The fuel burns inside the furnace core and forms ash, which falls through the ash outlet into the ash collection box for collection. Once the box is full, it can be removed to dispose of the ash.

[0004] However, during fuel combustion, flue gas and high-temperature air are produced. The airflow may flow out from the ash outlet, which can easily blow the furnace ash in the ash collection box, causing dust. Furthermore, because part of the airflow flows out from the ash outlet, it causes the airflow inside the furnace to be diverted, affecting fuel combustion. Utility Model Content

[0005] The purpose of this application is to provide a clean heating stove that can seal the ash outlet to prevent dust from rising and ensure that the airflow flows from bottom to top to ensure smooth fuel combustion.

[0006] The clean heating stove provided in this application adopts the following technical solution: A clean heating stove, comprising: shell; A furnace core is installed on the outer shell and has an ash outlet at its lower end; the furnace core is provided with a furnace chamber. A dust collection box, which is slidably disposed on the outer shell and located below the dust outlet; A baffle is slidably disposed at the lower end of the furnace core and is used to close or open the ash outlet.

[0007] Optionally, it also includes a push plate, a guide rod, and an elastic element. A frame is fixedly connected to the outer shell. The guide rod is fixed to the frame. The push plate is slidably disposed on the guide rod and can move in a direction close to or away from the baffle. The push plate abuts against the baffle. One end of the elastic element acts on the guide rod, and the other end acts on the push plate and is in a compressed state.

[0008] Optionally, at least one pair of guide rods are provided, and at least one pair of guide rods are located at both ends of the push plate. Both ends of the push plate are slidably disposed on the corresponding guide rods, and each guide rod is provided with the elastic element.

[0009] Optionally, a pull rod is also included, which is fixedly connected to the baffle and extends out of the housing.

[0010] Optionally, the furnace core includes a furnace body and a furnace shell. The furnace body is installed inside the furnace shell and there is a cavity between the furnace body and the furnace shell. A slag discharge port is provided on the furnace body and communicates with the cavity. A slag outlet is provided at the bottom of the furnace shell and the slag outlet corresponds to the position of the slag discharge port.

[0011] Optionally, the baffle can simultaneously close the slag outlet and the ash outlet.

[0012] This application first seals the ash outlet by setting a baffle, ensuring that the airflow can only flow from bottom to top, preventing air leakage and thus avoiding dust generation, while also ensuring smooth fuel combustion. Simultaneously, it seals the slag outlet, ensuring no air leakage at the slag outlet location and guaranteeing smooth airflow.

[0013] This application also includes an elastic element and a push plate. Through the cooperation of the elastic element and the push plate, the baffle is always pressed against the furnace shell, avoiding air leakage caused by wear of the baffle due to long-term use. Attached Figure Description

Detailed Implementation

[0018] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail below.

[0019] A clean heating stove, as shown in the reference Figure 1 It includes an outer shell 1, a furnace core 2, a feeding device 3 and an ash receiving box 4. The furnace core 2 is fixedly installed inside the outer shell 1. An ash outlet 23 is opened at the lower end of the furnace core 2. A furnace chamber 221 is provided inside the furnace core 2. The furnace chamber 221 is used to place fuel for combustion. Specifically, a furnace bridge 25 is installed inside the furnace chamber 221. The fuel is placed on the furnace bridge 25 for combustion.

[0020] The feeding device 3 is fixedly installed on the side wall of the outer shell 1 and connected to the furnace 221. The feeding device 3 is used to transport fuel into the furnace 221. Specifically, the feeding device 3 adopts auger feeding, which transports biomass pellets into the furnace 221 through the auger, so that the biomass pellets accumulate on the furnace bridge 25 for combustion.

[0021] The ash collection box 4 is slidably installed on the outer shell 1 and located below the ash outlet 23. Specifically, a dummy is fixed to the lower part of the outer shell 1, and the ash collection box 4 is slidably installed on the frame 11. When the fuel is burned, the generated furnace ash falls from the ash outlet 23 and falls into the ash collection box 4 for collection.

[0022] Reference Figure 1 and Figure 2 Furthermore, it also includes a baffle 5, which is slidably installed at the lower end of the furnace core 2 and is used to close or open the ash outlet 23. During fuel combustion, the temperature inside the furnace is high. If there is no need to heat food, the top of the furnace needs to be covered, leaving only a gap for the flue gas to escape. This prevents the fire from rising while ensuring the flow of flue gas, thereby reducing damage to the furnace panel. However, because the gap is small, the air pressure inside the furnace can easily increase. At this time, hot air can easily flow out from the ash outlet 23, blowing up the ash and causing dust. In addition, the hot air and flue gas cannot flow smoothly from the top, resulting in poor airflow and incomplete fuel combustion.

[0023] By setting up baffle 5, the ash outlet 23 is sealed during fuel combustion, preventing flue gas and hot air from flowing out of the ash outlet 23. This ensures that the airflow can only flow from bottom to top, guaranteeing smooth airflow and complete fuel combustion. Furthermore, since there is no airflow at the ash outlet 23, the impact of the airflow on the furnace ash in the ash box 4 is avoided, thus preventing dust generation.

[0024] In some embodiments, a pull rod 51 is fixedly connected to the baffle 5. The pull rod 51 extends out of the outer shell 1 and is slidably connected to the outer shell 1. The user can drive the baffle 5 to slide by pulling the pull rod 51, thereby opening or closing the ash outlet 23. When ash needs to be cleaned, the ash outlet 23 can be opened by pulling the pull rod 51, so that the furnace ash falls into the ash collection box 4 for collection, which is convenient for cleaning.

[0025] In some embodiments, the furnace core 2 includes a furnace body 22 and a furnace shell 21. The furnace shell 21 is fixed inside the outer shell 1. The furnace body 22 is fixedly installed inside the furnace shell 21 and there is a cavity 24 between the furnace body 22 and the furnace shell 21. The furnace chamber 221 is located inside the furnace body 22. A natural air inlet is provided on the furnace body 22. The natural air inlet passes through the outer shell 1 and communicates with the outside.

[0026] In some embodiments, a blower 6 is also included. The blower 6 is connected to the cavity 24 and is used to supply air into the cavity 24. Ventilation holes are also provided on the furnace body 22, which are connected to the furnace chamber 221 and the cavity 24 respectively. By supplying air into the cavity 24, the blower 6 achieves secondary air intake into the furnace chamber 221, thereby controlling the fire intensity within the furnace chamber 221. Because the blower 6 ventilates into the furnace chamber 221, the pressure inside the furnace chamber 221 increases. The baffle 5 ensures that air can only flow upwards, preventing incomplete combustion of fuel due to obstructed airflow.

[0027] Furthermore, a slag discharge port 222 is provided on the side wall of the furnace body 22. The slag discharge port 222 is connected to the cavity 24. Fuel burns on the furnace bridge 25 to form slag, which accumulates on the furnace bridge 25. During the auger feeding process, fuel enters the furnace chamber 221 and pushes the slag towards the slag discharge port 222, causing the slag to fall from the slag discharge port 222 into the cavity 24. This prevents the slag from accumulating on the furnace bridge 25.

[0028] Furthermore, a slag outlet 211 is provided at the bottom of the furnace shell 21. The slag outlet 211 corresponds to the slag discharge outlet 222. The slag falls from the slag discharge outlet 222 into the cavity 24 and then flows out of the slag outlet 211 into the ash collection box 4 for collection. The ash collection box 4 corresponds to both the ash outlet 23 and the slag outlet 211, and can collect furnace ash and slag at the same time.

[0029] Furthermore, the baffle 5 can simultaneously close the slag outlet 211 and the ash outlet 23. When the fuel is burning, the blower 6 ventilates the cavity 24. At this time, the airflow may flow out from the slag outlet 211, causing dust. At this time, the baffle 5 can simultaneously close the ash outlet 23 and the slag outlet 211 to prevent the airflow from flowing out from the slag outlet 211 and ensure the smooth flow of airflow.

[0030] Reference Figure 1 and Figure 3Furthermore, it also includes a push plate 7, a guide rod 8, and an elastic element 9. The guide rod 8 is fixedly connected to the frame 11. The push plate 7 is slidably disposed on the guide rod 8 and can move towards or away from the baffle 5, and the push plate 7 is always in contact with the baffle 5. One end of the elastic element 9 acts on the push plate 7, and the other end acts on the guide rod 8 or the frame 11. Specifically, the elastic element 9 is a spring, with one end fixedly connected to the push plate 7 and the other end fixedly connected to the guide rod 8. In other embodiments, it can also be fixedly connected to the frame 11. The elastic element 9 is always in a compressed state, always pushing the push plate 7 towards the baffle 5, so that the push plate 7 always pushes the baffle 5 towards the furnace shell 21, making the baffle 5 fit tightly against the furnace shell 21.

[0031] During long-term use, the baffle 5 will wear against the furnace shell 21, causing gaps between the baffle 5 and the furnace shell 21, which can easily lead to air leakage. Due to the setting of the elastic element 9, the push plate 7 always pushes the baffle 5 to abut against the shell, ensuring that the baffle 5 and the furnace shell 21 are always tightly fitted, avoiding air leakage and ensuring the stability of combustion in the furnace.

[0032] Furthermore, at least one pair of guide rods 8 are provided, and at least one pair of guide rods 8 are located at both ends of the push plate 7. Both ends of the push plate 7 are slidably mounted on the corresponding guide rods 8. Each guide rod 8 is provided with the aforementioned elastic element 9. Since the elastic element 9 is provided at both ends of the push plate 7, the pushing force at both ends of the push plate 7 is balanced, ensuring that the push plate 7 is always in contact with the baffle 5, and preventing the push plate 7 from tilting up at one end.

[0033] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
