Technical Field
[0001] This utility model relates to the field of fireplace technology, and in particular to a freestanding wood-burning fireplace with a water tank. Background Technology
[0002] Wood-burning fireplaces, a time-honored heating method, still hold an important place in many homes due to their unique visual appeal and comfortable heat transfer. The design of a wood-burning fireplace typically includes a wall-mounted fireplace body with an observation glass panel on the door, allowing users to both add wood and appreciate the flickering flames.
[0003] Currently, traditional wood-burning fireplaces typically need to be permanently installed in the living room because they require adequate ventilation and safety measures. Since wood-burning fireplaces provide heat by burning wood, the resulting flames and smoke can negatively impact indoor air quality, and improper installation poses a high fire risk. Therefore, most traditional fireplaces can only be installed in open areas such as living rooms with good ventilation, and cannot be widely used in bedrooms or other more enclosed rooms. They often fail to effectively transfer heat to bedrooms or other rooms, resulting in unsatisfactory heating in these spaces. Utility Model Content
[0004] The purpose of this invention is to solve the problem that most traditional fireplaces cannot be widely used in bedrooms or other relatively enclosed rooms, resulting in unsatisfactory heating effects in these rooms. This invention provides a freestanding wood-burning fireplace with a water tank that can transfer heat to other rooms, thus solving the problem of limited heating range of traditional fireplaces.
[0005] To achieve the above objectives, this utility model provides an independent wood-burning fireplace with a water tank, including a fireplace body. The fireplace body has a shelf inside for holding wood, and an installation cavity is opened inside the fireplace body. A stainless steel water tank is installed inside the installation cavity. A cover plate is detachably connected to the fireplace body. An inlet pipe and an outlet pipe are connected to the stainless steel water tank. The outlet pipe is connected to a radiator. A fire baffle is provided inside the fireplace body.
[0006] As a further description of the above technical solution: the furnace body is provided with a furnace door on the outside, the furnace door is provided with an observation glass, the furnace body is provided with an air inlet pipe inside, and the furnace body is provided with a smoke outlet pipe at the back.

The main tank body is connected to the inlet pipe and the outlet pipe.
[0008] As a further description of the above technical solution: the stainless steel water tank is detachably connected to the mounting cavity by bolts.
[0009] As a further description of the above technical solution: the fire baffle includes a first fire baffle and a second fire baffle, the first fire baffle is installed inside the furnace body, and the second fire baffle is installed below the first fire baffle.
[0010] As a further description of the above technical solution: there are two water inlet pipes and two water outlet pipes, with the water inlet pipe located below the water outlet pipe.
[0011] As a further description of the above technical solution: an air outlet plate is connected to the air inlet pipe, and the air outlet plate is provided with multiple air outlet holes.
[0012] As a further description of the above technical solution: the first fire baffle is a square plate, and the second fire baffle is an annular plate.
[0013] The above technical solution has the following advantages or beneficial effects:
[0014] This invention utilizes an internal cavity within the furnace body to house a stainless steel water tank, making efficient use of the furnace's internal space to integrate combustion heating and water circulation heating functions.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] In the description of this utility model, it should be noted that the terms "vertical", "up", "down", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0024] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0025] like Figure 1-5 As shown, this utility model discloses an independent wood-burning fireplace with a water tank, comprising a furnace body 1, a shelf 2 for holding wood inside the furnace body 1, an installation cavity 3 inside the furnace body 1, a stainless steel water tank 4 installed inside the installation cavity 3, a cover plate 5 detachably connected to the furnace body 1, an inlet pipe 6 and an outlet pipe 7 connected to the stainless steel water tank 4, the outlet pipe 7 being connected to a radiator, and a fire baffle plate 8 inside the furnace body 1.
[0026] In the technical solution of this utility model, the mounting cavity 3 inside the furnace body 1 is used to accommodate the stainless steel water tank 4, making reasonable use of the internal space of the furnace body to achieve the integration of combustion heating and water circulation heating functions. The shelf 2 provides stable support for the wood, keeping the wood at a suitable burning distance, ensuring air circulation, promoting complete combustion of the wood, and improving heat generation efficiency. By using the heat generated by the burning wood to heat the water in the stainless steel water tank 4, the heat energy of combustion is converted into the internal energy of the water, achieving efficient heat recovery. The water is connected to the radiator through the inlet pipe 6 and the outlet pipe 7 to form a water circulation system. Hot water flows out from the outlet pipe 7 and enters the radiator to dissipate heat. The cooled water flows back to the water tank through the inlet pipe 6 for reheating, realizing the transfer of heat to other rooms and solving the problem of limited heating range of traditional fireplaces.
[0027] like Figure 1 and Figure 2 As shown, the furnace body 1 is equipped with a furnace door 9 on the outside, and an observation glass 10 on the furnace door 9. An air inlet pipe 11 is installed inside the furnace body 1, and a smoke outlet pipe 12 is installed on the back of the furnace body 1. The observation glass 10 is made of high-temperature resistant material, allowing users to observe the internal combustion without opening the furnace door, avoiding heat loss and the risk of flame burns. It also facilitates timely monitoring of the wood burning status and adjusting the timing of adding fuel. The smoke outlet pipe 12 is connected to a smoke guide pipe to exhaust the smoke and exhaust gas produced by combustion to the outside, preventing smoke from accumulating indoors, improving indoor air quality, maintaining the pressure balance inside and outside the furnace, ensuring smooth combustion, and reducing the risk of fire and carbon monoxide poisoning.
[0028] like Figure 1 and Figure 4 As shown, the stainless steel water tank 4 includes a main tank 41, which is installed on the back of the furnace body 1. Side tanks 42 are provided on both sides of the main tank 41, and the side tanks 42 are installed on both sides of the furnace body 1. The main tank 41 is connected to the inlet pipe 6 and the outlet pipe 7. The main tank 41 is installed on the back of the furnace body 1, and the side tanks 42 are distributed on both sides of the furnace body. This layout greatly increases the contact area between the water tank and the flame and high-temperature area inside the furnace body. The space on the back and sides of the furnace body can be fully utilized, avoiding the space waste caused by the single shape of the water tank. The heat generated by the burning of wood can be transferred to the water tank from multiple directions. Compared with a single tank structure, it can absorb the combustion heat energy more fully and convert more combustion heat energy into the internal energy of water, improve the heat conversion efficiency, and provide a sufficient heat source for water circulation heating.
[0029] The stainless steel water tank 4 is detachably connected to the installation cavity 3 by bolts. The detachable design facilitates the installation, maintenance and replacement of the stainless steel water tank 4. At the same time, the combined structure of the main body 41 and the side body 42 can adapt to different furnace sizes and installation requirements, improving the equipment's versatility.
[0030] like Figure 1 and Figure 5 As shown, the fire baffle 8 includes a first fire baffle 81 and a second fire baffle 82. The first fire baffle 81 is installed inside the furnace body 1, and the second fire baffle 82 is installed below the first fire baffle 81. The first fire baffle 81 can prevent the flame from spreading directly upward and guide the flame to spread to the sides or downward, so that the flame can fully contact the stainless steel water tank and improve the heat transfer efficiency. The second fire baffle 82 further changes the flame path, so that the heat is more evenly distributed in the furnace body, avoiding local overheating. At the same time, it reduces the high-temperature erosion of specific parts of the furnace body by the flame, extends the service life of the furnace body, reduces the risk of flame spread by blocking the flame, reduces fire hazards, and improves the safety of fireplace use.
[0031] The first fire baffle 81 is a square plate, and the second fire baffle 82 is a ring plate.
[0032] like Figure 1 and Figure 2 As shown, there are two inlet pipes 6 and two outlet pipes 7, with the inlet pipe 6 located below the outlet pipe 7.
[0033] like Figure 1 and Figure 2 As shown, an air outlet plate 13 is connected to the air inlet pipe 11, and multiple air outlet holes 14 are provided on the air outlet plate 13. The air inlet pipe 11 introduces external air into the furnace body to provide sufficient oxygen for wood combustion, ensure complete combustion, and improve heat generation efficiency. The multiple air outlet holes 14 on the air outlet plate 13 can disperse the air, so that the air is evenly distributed in the furnace body. At the same time, a control valve is provided on the air inlet pipe 11. By controlling the air inlet pipe valve, the amount of air entering the furnace body can be adjusted, thereby controlling the combustion speed and flame size to meet different heating needs.
[0034] Working principle: Open the furnace body through cover plate 5, place the burning wood on the shelf 2, and close the cover plate; install the stainless steel water tank 4 in the installation cavity 3 with bolts, and connect the inlet pipe 6 and outlet pipe 7 to the radiator pipes; open the furnace door 9 and ignite the burning wood; introduce air through the air inlet pipe 11 to assist combustion; the burning wood produces flames and heat. The fire baffle plate 8 guides the flames, allowing heat to be evenly transferred to the stainless steel water tank 4, heating the water in the tank. The heated water flows into the radiator through the outlet pipe 7 for heat dissipation, and the cooled water flows back to the water tank through the inlet pipe 6 for reheating, realizing the circulation of heat between different rooms. The smoke produced by combustion is discharged outdoors through the smoke outlet pipe 12. The observation glass 10 facilitates real-time monitoring of the combustion status. The furnace door 9 and the fire baffle plate 8 ensure safety during use, preventing flame escape and disorderly heat diffusion.
[0035] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
