[0003] The principle of a fireplace is usually to intake outside air through the air inlet, heat it through an electric heater or fuel inside the fireplace, and then discharge it from the air outlet through a blower.

[0024] The present invention has the following beneficial effects:

[0025] 1.

Moreover, the secondary hot air is annularly wrapped outside the main hot air, which can make the relatively hotter main hot air be constrained and concentrated, avoiding heat dissipation at the conical boundary, and making the hot air flow blow more concentratedly into the room for heating.

[0026] 2. When the unidirectional heat-conducting fireplace continuously pumps the heat-conducting liquid into the first water pipe installed in the heat-conducting plate through the liquid pump, it uses the power of the self-flow of the heat-conducting liquid to drive the operation of the unidirectional water-pumping component, so that part of the circulating heat-conducting liquid enters the third water pipe. The heat-conducting liquid in multiple third water pipes converges and then enters the heat-dissipating pipe installed at the auxiliary air outlet to dissipate heat, and finally the heat-conducting liquid returns to the water tank to form an overall cycle. Through continuous cycle heating, the problem that the heat dissipated when the heat-conducting liquid flows through the heat-dissipating pipe at one time is incomplete can be avoided.

[0027] 3. For the unidirectional heat-conducting fireplace, the size of the auxiliary hot air formed by the auxiliary air outlet can also be adjusted. By rotating the forward and reverse rotation knob, the retractable rectangle that blocks part of the auxiliary air outlet can be scaled, so that the size of the conical air flow formed by the combined force of the auxiliary hot air and the main hot air can be adjusted.

Embodiment

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0041] In order to enable the heat generated by the heating device in the fireplace to be concentrated on the air outlet side to the greatest extent, and to avoid dissipating too much heat to the other five inner walls of the fireplace and then further dissipating it into the wall where the fireplace is installed, resulting in waste, Embodiment 1 is proposed;

[0042] Please refer to Figures 1-11 , a one-way heat conduction fireplace, including a fireplace main body 100, an electric heater 110 is arranged in the fireplace main body 100, an air inlet grille 120 and an air outlet grille 130 are further arranged on the fireplace main body 100, a main air outlet 140 and a secondary air outlet 150 are arranged on the air outlet grille 130, and the secondary air outlet 150 is annularly arranged outside the main air outlet 140, and a heat dissipation pipe 180 is arranged on the air outlet grille 130 corresponding to the secondary air outlet 150;

[0043] A fan 160 is arranged on one inner wall of the fireplace main body 100 close to the air outlet grille 130, and the output end of the fan 160 is aligned with the main air outlet 140, and a heat collection mechanism 200 is arranged on the remaining several inner walls of the fireplace main body 100;

[0044] Through the operation of the fan 160 and several heat collection mechanisms 200, the heat generated when the electric heater 110 operates is concentrated and conducted to the air outlet grille 130 to achieve one-way heat conduction;

[0045] A water tank 170 is provided on the fireplace main body 100, and a heat-conducting liquid is stored in the water tank 170. The heat dissipation pipe 180 is communicated with the water tank 170;

[0046] The heat collection mechanism 200 includes a heat-conducting plate 210 provided on the inner wall of the fireplace main body 100. A first water pipe 220 is arranged in the heat-conducting plate 210. A liquid pump 270 is arranged in the water tank 170. One end of the first water pipe 220 is connected to the liquid pump 270, and the other end of the first water pipe 220 is communicated with the water tank 170. The heat generated by the electric heater 110 during operation and dissipated to the inner wall of the fireplace main body 100 is collected by the heat-conducting plate 210 to heat the heat-conducting liquid in the first water pipe 220;

[0047] A second water pipe 230 is further arranged on the first water pipe 220. The second water pipe 230 is communicated with the heat dissipation pipe 180 through a third water pipe 240, and several third water pipes 240 are communicated with each other;

[0048] The second water pipe 230 is communicated with the third water pipe 240 through a connecting pipe 250. A one-way water pumping assembly 260 is arranged in the connecting pipe 250. The one-way water pumping assembly 260 is used to pump the heat-conducting liquid in the first water pipe 220 into the heat dissipation pipe 180 through the connecting pipe 250.

[0049] In this embodiment: The electric heater 110 is selected as the heating device installed in the fireplace main body 100 to form an electric fireplace. Similarly, the electric heater 110 can also be a heating device that burns wood or other fuels.

[0050] First, the outside air entering the fireplace main body 100 through the air inlet grille 120 is heated by the electric heater 110, and then the blower 160 operates to blow air to the main air outlet 140, so that the heat is mainly blown out from the main air outlet 140 through the hot air flow.

[0051] At the same time, part of the heat is also dissipated to the remaining inner walls of the fireplace main body 100, including the upper, lower, left, right, and rear sides. At this time, the heat collection mechanism 200 arranged on the inner walls of the other five sides can collect and conduct the waste heat to the secondary air outlet 150. The secondary air outlet 150 is in a rectangular ring shape. The waste heat is dissipated through the secondary air outlet 150 to achieve one-way heat conduction to the greatest extent, and as Figure 11 shown, the hot air flow dissipated from the secondary air outlet 150 will wrap the hot air flow dissipated from the main air outlet 140, forming a constraining and aggregating effect.

[0052] It is possible to prevent the heat dissipated from the main air outlet 140 from being dissipated at the boundary of the conical air flow. Through constraint and aggregation, the main hot air flow emitted from the main air outlet 140 can be released more concentratedly, facilitating indoor heating.

[0053] Specifically, taking the heat collection mechanism 200 located at the rear side as an example, the waste heat of the inner wall at the rear side is collected through the heat conduction plate 210. The heat conduction plate 210 can be made of a phase change energy storage material. Specifically, reference can be made to a storage type movable fuel heater disclosed in the comparative document CN113124447A.

[0054] The liquid pump 270 operates to continuously pump the heat conduction liquid in the water tank 170 into the first water pipe 220, circulate in the spiral-shaped first water pipe 220, and then return to the water tank 170. The first water pipe 220 is set in a spiral shape to increase the heat absorption area of the first water pipe 220 in the heat conduction plate 210. Subsequently, during the circulation of the heat conduction liquid, a part of the heat conduction liquid is pumped upward into the second water pipe 230 through the one-way pumping assembly 260, and then enters the third water pipe 240 through the connecting pipe 250.

[0055] Finally, the heat conduction liquid in multiple third water pipes 240 converges and enters the heat dissipation pipe 180. The heat is dissipated at the secondary air outlet 150 and blown out along with the airflow generated by the fan 160. The heat conduction liquid in the heat dissipation pipe 180 finally returns to the water tank 170 again. The heat conduction liquid is continuously circulated in the fireplace main body 100 and heated by the waste heat. The fireplace main body 100 is an insulating housing, and the heat conduction liquid can be water, or a refrigerant in an air conditioner, or other liquids with a large specific heat capacity. Embodiment

[0056] To continuously extract a part of the heat conduction liquid in the first water pipe 220 into the third water pipe 240, Embodiment 2 is proposed;

[0057] This embodiment is an improved explanation based on Embodiment 1. Specifically, please refer to Figures 3-10 , the one-way pumping assembly 260 includes a fixing plate 261 and a piston 262 arranged in the connecting pipe 250. Check valves 263 are arranged on both the fixing plate 261 and the piston 262. The check valves 263 are used to limit the heat conduction liquid to only flow from the side of the first water pipe 220 to the side of the third water pipe 240;

[0058] A sliding groove 264 is formed in the connecting pipe 250. A sliding plate 265 is slidably arranged in the sliding groove 264. The sliding plate 265 is connected to the piston 262 through a connecting member 266;

[0059] The one-way pumping assembly 260 further includes a reciprocating motion assembly 267 connected to the sliding plate 265. The reciprocating motion assembly 267 is used to drive the sliding plate 265 to reciprocate in the sliding groove 264;

[0060] The reciprocating motion assembly 267 includes an external cavity 2671 provided on the first water pipe 220. A rotating rod 2672 is rotatably provided on the external cavity 2671. One end of the rotating rod 2672 located inside the first water pipe 220 is provided with an impeller 2673. The other end of the rotating rod 2672 located outside the first water pipe 220 is coaxially provided with a turntable 2674. A connecting shaft 2675 is provided at the edge of the turntable 2674;

[0061] The reciprocating motion assembly 267 further includes a connecting rod 2676. One end of the connecting rod 2676 is rotatably connected to the connecting shaft 2675. The other end of the connecting rod 2676 is movably hinged to the sliding plate 265 through a hinge shaft;

[0062] The one-way pumping assembly 260 further includes a sealing groove 268 opened on the connecting pipe 250. The sealing groove 268 communicates with the sliding groove 264. A sealing plate 269 is provided on the sliding plate 265. The sealing plate 269 is slidably connected in the sealing groove 268.

[0063] In this embodiment: When most of the heat-conducting liquid in the first water pipe 220 passes through the spiral track of the first water pipe 220 and is in the external cavity 2671 installed in its straight section, the heat-conducting liquid will continuously push the impeller 2673 and the rotating rod 2672 to rotate. Since the impeller 2673 keeps the upper part in contact with the liquid, it will rotate in one direction as much as possible. Then it drives the turntable 2674 to rotate. Through the transmission of the connecting shaft 2675 and the connecting rod 2676, the sliding plate 265, the piston 262 and the one-way valve 263 fixed on the piston 262 slide left and right continuously.

[0064] When the piston 262 and the one-way valve 263 fixed on the piston 262 move to the right, the one-way valve 263 on the right closes, while the one-way valve 263 at the fixed position on the left opens, creating a vacuum environment between the two one-way valves 263. Under the pressure difference, part of the heat-conducting liquid in the first water pipe 220 is pumped into the space between the two one-way valves 263. When the one-way valve 263 on the right moves to the left, the one-way valve 263 on the left closes, and the one-way valve 263 on the right opens, allowing the heat-conducting liquid to enter the right side of the connecting pipe 250 and enter the third water pipe 240. In this way, it can continuously pump part of the liquid in the first water pipe 220 into the third water pipe 240.

[0065] The sealing plate 269 fixed on the sliding plate 265 slides in the sealing groove 268 with a larger length, always maintaining a sealed state, which plays a role in preventing the heat-conducting liquid from flowing out and maintaining the seal. Embodiment

[0066] In order to make the size of the secondary hot air generated by the secondary air outlet 150 adjustable, so as to facilitate adjusting the area of the conical air flow formed by the combined force of the main hot air and the secondary hot air to adjust the heating effect, Embodiment 3 is proposed;

[0067] This embodiment is an improved description based on Embodiment 1. Specifically, please refer to Figures 1-8 , an adjusting mechanism 300 for adjusting the area of the auxiliary air outlet 150 is further provided in the fireplace main body 100. The adjusting mechanism 300 includes four L-shaped wind shields 310 and four straight wind shields 320 that are slidably arranged in the fireplace main body 100;

[0068] Both ends of the four L-shaped wind shields 310 are open, and both ends of the four straight wind shields 320 are slidably connected to several openings of the four L-shaped wind shields 310 respectively;

[0069] A rectangular shape is formed by the four L-shaped wind shields 310 and the four straight wind shields 320;

[0070] Guide rods 330 are arranged on all four L-shaped wind shields 310. Four guide grooves 340 are formed in the fireplace main body 100. The four guide rods 330 are respectively slidably connected to the four guide grooves 340, and the four guide grooves 340 are respectively distributed along the diagonals of the rectangle formed by the four L-shaped wind shields 310 and the four straight wind shields 320;

[0071] The adjusting mechanism 300 further includes a lead screw 350 rotatably arranged on the fireplace main body 100. One of the L-shaped wind shields 310 is threadedly connected to one end of the lead screw 350 located inside the fireplace main body 100. A knob 360 is further arranged on the end of the lead screw 350 located outside the fireplace main body 100.

[0072] In this embodiment: The four L-shaped wind shields 310 form the corners of a rectangle, and the four straight wind shields 320 form the four sides of the rectangle. Thus, a retractable rectangle that fits the auxiliary air outlet 150 is formed. Since the four guide rods 330 fixed on the four L-shaped wind shields 310 slide along the four guide grooves 340 for limiting, when the upper L-shaped wind shield 310 moves up and down, the four straight wind shields 320 and the four L-shaped wind shields 310 move synchronously.

[0073] By rotating the knob 360 to drive the rotation of the lead screw 350, when the upper straight wind shield 320 moves upward, the rectangle expands, the area of the auxiliary air outlet 150 blocked decreases, and the air outlet increases. On the contrary, when the knob 360 rotates in the reverse direction to make the upper straight wind shield 320 move downward, the air outlet decreases.

[0074] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0075] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
