Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fireplaces, and specifically provides an embedded fireplace. Background Art
[0002] A fireplace is an indoor heating device that is independent or built into a wall. It uses combustible materials as energy and has a chimney inside. It is a home heating facility. Because its fuel is a renewable resource, it is still widely used after modern improvements. Fireplaces are mainly divided into open and closed types.
[0003] However, since the fireplace is embedded in the wall during installation, when the fireplace is working, the main heat inside it can only be dissipated from the front face of the fireplace, and the remaining heat in the fireplace will be transferred to the inside of the wall through the fireplace wall. The traditional embedded fireplace has a large heat energy loss when working, resulting in low thermal efficiency.
[0004] Therefore, there is an urgent need for an embedded fireplace that can reduce the heat energy loss of the fireplace and has a better heating effect to solve the above problems. Utility Model Content
[0005] The utility model aims to solve the above technical problem, that is, to solve the problem that the traditional embedded fireplace has a large heat energy loss during operation, resulting in low thermal efficiency.
[0006] The utility model provides an embedded fireplace, which comprises
[0007] Fireplace body;
[0008] a cover body, which is disposed on the fireplace body, the cover body at least partially surrounds the outside of the fireplace body, and a preheating channel for heating air is formed between the outer wall of the fireplace body and the cover body; and
[0009] The fan is arranged on the cover body, and the cover body has an air inlet and an air outlet. When the fan is working, the external air flow enters into the preheating channel through the air inlet and is discharged from the air outlet.
[0010] When the above technical solution is adopted, the indoor air will be sucked into the preheating channel driven by the fan, and the air inside the preheating channel will be heated by the heat emitted from the side walls and the back of the fireplace body, and the heated air will be discharged into the room. On the one hand, the indoor temperature can be increased, and on the other hand, the heat emitted by the traditional fireplace to the surrounding walls can be transferred to the room, thereby improving the thermal efficiency of the fireplace.
[0011] Preferably, the front surface of the cover is flush with the front surface of the fireplace body.
[0012] When the above technical solution is adopted, when the airflow enters the preheating channel, it can completely contact the outer wall of the fireplace body, so as to fully receive the heat emitted from the side wall of the fireplace body and achieve the best preheating effect.
[0013] Preferably, the air inlet is arranged at a lower portion of the front surface of the cover body, and the air outlet is arranged at an upper portion of the front surface of the cover body.
[0014] When the above technical solution is adopted, the air flow with lower temperature close to the ground can be sucked into the preheating channel for heating, and then discharged from the upper air outlet, thereby increasing the indoor temperature.
[0015] Preferably, a first grille is provided at the air inlet, and a second grille is provided at the air outlet.
[0016] When the above technical solution is adopted, a better dust-proof effect can be achieved.
[0017] Preferably, an air duct is fixedly provided on the outer wall of the fireplace body, and the air duct has a first end and a second end opposite to each other, the first end is connected to the front surface of the cover body, and the second end is connected to the interior of the fireplace body.
[0018] Preferably, the first end is located at the lower part of the front surface of the cover body, dividing the air inlet into a first air inlet and a second air inlet.
[0019] By adopting the above technical solution, the indoor air with lower temperature close to the ground can be sucked into the air duct, thereby providing sufficient air for the interior of the fireplace body; since the air inlet and the air outlet are far apart, most of the air heated by the preheating channel will not enter the air duct, further increasing the indoor temperature.
[0020] Preferably, a chimney is arranged on the top of the fireplace body, one end of the chimney is connected to the interior of the fireplace body, and the other end passes through the cover body and is connected to the outside.
[0021] Preferably, a baffle for controlling the smoke exhaust volume is rotatably provided inside the chimney.
[0022] Preferably, the fireplace body further comprises a supporting column, one end of which is connected to the fireplace body, and the other end of which is connected to the inner wall of the bottom surface of the cover body or directly contacts the ground.
[0023] When the above technical solution is adopted, the cover body and the fireplace body can be stably connected together, and a gap will exist between the fireplace body and the cover body to form a preheating channel.

DETAILED DESCRIPTION
[0034] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not used to limit the protection scope of the present invention. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

In addition, ordinal numbers such as "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0036] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0037] Reference Figure 1-2 The present application provides an embedded fireplace, in which a cover body 1 is provided on the outside of a fireplace body 2, the cover body 1 at least partially surrounds the outside of the fireplace body 2, and a preheating channel 3 for heating air is formed between the outer wall of the fireplace body 2 and the cover body 1; through the above design, a traditional independent closed fireplace has the function of warming air.
[0038] For the convenience of description, the present application refers to the surface of the fireplace body 2 facing the room as the front surface. Similarly, the cover body 1 also has a front surface. It should be noted that the above-mentioned cover body 1 at least surrounds the outside of the fireplace body 2, which means that the cover body 1 can be completely surrounded by the outside of the fireplace body 2, or it can be half-surrounded by the outside of the fireplace body 2 to expose the front end surface of the fireplace body 2. For example, the front surface of the cover body 1 is flush with the front surface of the fireplace body 2, or the front surface of the cover body 1 protrudes from the front surface of the fireplace body 2. For the above situation, as long as the preheating channel 3 can be formed between the cover body 1 and the fireplace body 2, the present application does not make any specific restrictions on this.
[0039] By delivering the indoor air to the preheating channel 3, using the heat emitted from the side walls and the back of the fireplace body 2 to heat the air inside the preheating channel 3, and then delivering the heated air to the room, not only can the indoor temperature be increased, but also the heat energy loss caused by the fireplace body 1 transferring heat to the inside of the wall can be reduced, thereby improving the thermal efficiency of the fireplace when it is working.
[0040] The fan 23 is arranged on the cover 1, and the cover 1 has an air inlet and an air outlet. According to the actual situation, the fan 23 can be installed near the air inlet or near the air outlet. When the fan 23 is working, the external air flows into the preheating channel 3 through the air inlet and is discharged from the air outlet. When the air circulates inside the preheating channel 3, the heat emitted by the outer wall of the fireplace can heat the air, and then the heated air will be discharged from the air outlet, thereby increasing the indoor temperature.
[0041] Optionally, two fans 23 are provided, both of which are arranged below the fireplace body 2 and perpendicular to the bottom surface of the fireplace body 2, and the input ends of the fans 23 are both facing the air inlet 16, so as to quickly draw indoor air into the preheating channel 3 for heating.
[0042] Reference Figure 3-4 , the front surface of the cover 1 is flush with the front surface of the fireplace body 2; when the front surfaces of the two are flush, the air inside the preheating channel 3 can be fully in contact with the outer wall of the fireplace body 2, thereby achieving sufficient preheating, and it is also convenient for the air in the preheating channel 3 to be quickly discharged. There will be no situation where the front surface of the cover 1 is located behind the front surface of the fireplace body 2, causing the outer wall of the fireplace body 2 exposed outside the cover 1 to still transfer heat to the wall; there will also be no situation where the front surface of the cover 1 exceeds the front surface of the fireplace body 2, causing the air inside the preheating channel 3 to be inconvenient to be discharged or the protruding edge of the front surface of the cover 1 to cause danger to indoor personnel.
[0043] The air inlet 16 is arranged at the lower part of the front surface of the cover body 1, and the air outlet 15 is arranged at the upper part of the front surface of the cover body 1. Since the air expands and rises due to heat, the air temperature at the position close to the ground in the room is lower than that at the position far from the ground in the room. By arranging the air inlet 16 at the bottom of the cover body 1, a large amount of air with a lower indoor temperature can be quickly sucked into the preheating channel 3, and the heated air in the preheating channel 3 will rise when discharged from the air outlet 15, and will not enter the preheating channel 3 again from the air inlet 16. The reasonable layout of the air inlet 16 and the air outlet 15 can quickly heat the indoor air and circulate the air quickly.
[0044] Furthermore, a first grille 11 is provided at the air inlet 16, and a second grille 12 is provided at the air outlet 15. The first grille 11 and the second grille 12 can reduce the amount of dust entering the preheating channel 3, improve the cleanliness of the preheating channel 3, and do not need to clean the preheating channel 3 frequently.
[0045] Reference Figure 5 The outer wall of the fireplace body 2 is fixedly provided with an air duct 4, and the air duct 4 has a first end 11 and a second end 12 opposite to each other. The first end 11 is connected to the front surface of the cover body 1, and the second end 12 is connected to the interior of the fireplace body 2. The first end 11 of the air duct 4 is an air inlet end, and the second end 12 of the air duct 4 is an air outlet end. The first end 11 is located at the lower part of the front surface of the cover body 1, and the air inlet 16 is divided into a first air inlet 161 and a second air inlet 162. When the fireplace is working, oxygen is consumed inside and smoke is discharged at the same time. Therefore, when the fireplace is working, a continuous supply of air is required to ensure the air pressure balance inside. Therefore, air will be sucked into the fireplace along the air duct 4 by the fireplace.
[0046] The present application is a dual air inlet system, which can not only provide sufficient air for combustion inside the fireplace body 2, but also inhale the indoor air, heat it and blow it out to form warm air.
[0047] Furthermore, the air duct 4 is C-shaped, the tube body of the air duct 4 is fixedly connected to the middle of the outer wall of the fireplace body 2, the second end 12 of the air duct 4 is connected to the top of the fireplace body 2, and the air duct 4 is provided with an annular through hole near the chimney 21. The annular channel is used to fix the chimney 21, and the annular channel can also be connected to the chimney 21 to play a fixing role, which is beneficial to stabilizing the chimney 21 and the air duct 4.
[0048] Reference Figure 6 One end of the chimney 21 is connected to the interior of the fireplace body 2, and the other end passes through the cover body 1 and is connected to the outside. The chimney 21 is used to discharge the smoke generated inside the fireplace to the outside of the fireplace.
[0049] Furthermore, a baffle 211 for controlling the amount of smoke exhaust is rotatably provided inside the chimney 21. A rotating shaft 212 is fixedly connected to the middle of the baffle 211, and the rotating shaft 212 is rotatably connected to the chimney 21. One end of the rotating shaft 212 located outside the chimney 21 is connected to the outer wall of the fireplace body 2. When the baffle 211 needs to be rotated, the deflection angle of the baffle 211 can be controlled by rotating the rotating shaft 212, thereby realizing the control of the amount of smoke exhaust.
[0050] When the above technical solution is adopted, since the air duct 4 absorbs air from the outside to the inside of the fireplace by negative pressure attraction, by changing the deflection angle of the baffle 211, the air intake volume inside the fireplace can be changed while controlling the smoke exhaust volume, and then by controlling the combustion speed of the fuel inside the fireplace body 1, the indoor temperature can be finally controlled.
[0051] The fireplace body 2 further includes a support column 22, one end of which is connected to the fireplace body 2, and the other end is connected to the inner wall of the bottom surface of the cover body 1 or directly contacts the ground. The support column 22 is used to support the fireplace body 2 and the cover body 1, and can fix the cover body 1 and the fireplace body 2 at the same time. At least two support columns 22 are provided, and the end of the support column 22 away from the fireplace body 2 can be directly fixedly connected to the ground, or directly connected to the inner side of the bottom surface of the cover body 1; when the support column 22 is directly connected to the inner side of the bottom surface of the cover body 1, the outer side of the bottom surface of the cover body 1 is directly fixedly connected to the ground, which can effectively improve the stability of the fireplace installation.
[0052] Furthermore, a connector 24 is installed on the side wall of the fireplace body 2, and the connector 24 is used to fix the cover body 1 on the fireplace body 2, so that there is a gap between the cover body 1 and the fireplace body 2, thereby forming a preheating channel 3 for heating the air; and after the connector 24 separates the cover body 1 from the fireplace body 2, it can also reduce the heat directly conducted from the fireplace to the cover body 1, which is then used to heat the air inside the preheating channel 3, thereby improving the thermal efficiency of the fireplace.
[0053] The top wall of the fireplace body 2 is a plane. Since the top of the traditional fireplace body 2 is covered with a cover, the present application changes the original cover into a plane structure, which can reduce the installation space of the fireplace.
[0054] Another embodiment of the present application is that it can be understood that the present application is also applicable to an independent fireplace that is not embedded in the wall, that is, a cover is provided on the outside of a traditional fireplace to heat the air sucked into the preheating channel and then blow it out, thereby increasing the indoor temperature and the thermal efficiency of the fireplace, so that the independent fireplace has the effect of warm air.
[0055] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
