Description

Technical Field

[0001] The invention relates to an energy gathering ring component and a gas stove. Background Art

[0002] Gas stoves are common household burners. The heat generated by a gas stove not only heats the pots and pans placed on it, but also heats the air surrounding the stove. This heated air can flow freely, carrying away the heat, significantly reducing the stove's thermal efficiency. Some gas stoves are equipped with a heat ring, which physically separates the flame from the outside air. This reduces the outward flow of air between the inner surface of the heat ring and the flame, improving the stove's thermal efficiency. Combustion produces flue gas, which carries a significant amount of heat. This flue gas is easily lost, causing heat loss during the exhaust process, which can also irritate users and cause other air pollution. Air outside the heat ring enters the gas stove, providing oxygen for fuel combustion. However, the air temperature is typically room temperature, significantly different from the ignition point of the gas. Existing technologies cannot effectively preheat the air outside this area. Furthermore, the heat exchange space is located close to the gas stove, which can easily damage the stove. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defects in the prior art that smoke easily loses heat and cannot preheat the air outside the energy-gathering ring well, and easily damages the gas stove, and provide an energy-gathering ring assembly and a gas stove.

[0004] The present invention solves the above technical problems through the following technical solutions:

[0005] A energy gathering ring assembly, which includes an energy gathering ring body and an exchanger. Several smoke inlets are opened on the inner side of the energy gathering ring body, and several smoke outlets are opened on the outer side of the energy gathering ring body. An air flow channel is provided in the energy gathering ring body. The exchanger is arranged in the air flow channel, and one end of the exchanger is connected to several of the smoke inlets, and the other end of the exchanger is connected to several of the smoke outlets.

[0006] In this solution, a smoke inlet is provided on the inner side of the energy gathering ring body and a smoke outlet is provided on the outer side, so that the smoke can flow in from the smoke inlet and out from the smoke outlet, and finally complete the heat exchange; secondly, an air flow channel is provided in the energy gathering ring body, and the exchanger is placed therein, and the two ends of the exchanger are respectively connected to the smoke inlet and the smoke outlet. The air entering the energy gathering ring body can fully contact the exchanger in the air flow channel and complete sufficient heat exchange with the smoke in the exchanger, which can: 1. Achieve the purpose of fully preheating the external air, and the preheated air contacts the burner to improve the combustion efficiency; 2. The exchanger is provided in the energy gathering ring body and does not directly contact the stove, so it is not easy to damage the stove body; 3. The smoke discharged from the energy gathering ring to the outside is less, and it is not easy to smoke the user.

[0007] Preferably, the exchanger includes a plurality of annular tubes, the plurality of annular tubes correspond one-to-one to the plurality of flue gas inlets and the plurality of flue gas outlets, and two ends of the annular tubes are respectively connected to the corresponding flue gas inlet and the flue gas outlet.

[0008] In this solution, the exchanger is configured as a number of annular tubes, which are arranged in a surrounding manner in the energy-gathering ring body. Firstly, the space occupied by the installation layout is saved; secondly, the annular arrangement can increase the area of contact between the smoke and the smoke, and maximize the contact between the smoke and the air through multiple layers of surrounding. The annular tubes are respectively connected to the smoke inlet and the smoke outlet. The smoke enters the annular tube from the smoke inlet, flows in from the initial end of the annular tube, and finally reaches the end of the annular tube after several layers of surrounding and flows out from the smoke outlet, maximizing the contact area of the heat exchange between the smoke and the air, and realizing the whole process from smoke entry to exhaust; thirdly, the exchanger is configured as an annular structure, and the smoke flowing in the tube is not easily discharged to the outside due to the ring, so it can avoid fumigating the user.

[0009] Preferably, the annular tube is distributed circumferentially in the air flow channel.

[0010] In this solution, the annular tubes are distributed around the air flow channel. After the external air enters the air flow channel, it contacts the layers of annular tubes, ultimately achieving sufficient heat exchange and fully preheating the air.

[0011] Preferably, the exchanger also includes a plurality of connecting tubes and a plurality of annular tubes, the plurality of connecting tubes corresponding one-to-one to the plurality of flue gas inlets and the plurality of flue gas outlets, and the two ends of the connecting tubes are respectively connected to the corresponding flue gas inlets and the flue gas outlets, and the two ends of the annular tubes are respectively connected to the two connecting tubes and communicate with the two connecting tubes.

[0012] In this solution, the connecting pipe is connected to the flue gas inlet and the flue gas outlet in a one-to-one correspondence, and the two ends of the annular tube are respectively connected to the two connecting pipes. Therefore, the connecting pipe runs through the annular tube, so that the flue gas can directly flow into the annular tube through the connecting pipe at one end and be discharged from the connecting pipe at the other end of the annular tube of this section, reducing the large air pressure difference in the cavity tube caused by excessive flue gas in the exchanger, avoiding excessive flue gas from accumulating in the cavity tube, and avoiding the cracking of the cavity tube.

[0013] Preferably, the connecting pipe is perpendicular to the annular pipe, and the connecting pipe is made of copper.

[0014] In this solution, the connecting pipe is arranged perpendicular to the annular pipe, so that the flue gas can flow directly into the annular pipe smoothly and avoid unnecessary obstruction. At the same time, the connecting pipe is made of copper, which has good thermal conductivity.

[0015] Preferably, the annular tube is distributed circumferentially in the air flow channel.

[0016] In this solution, the annular tubes are distributed around the air flow channel. After the external air enters the air flow channel, it contacts the layers of annular tubes, ultimately achieving sufficient heat exchange and fully preheating the air.

[0020] In this solution, the insulation cavity inside the energy-gathering ring body can isolate the heat inside the cavity from the outside world to prevent heat loss. At the same time, the insulation cavity and the flue gas inlet and outlet together form an air flow channel, which facilitates the influx of external air and sufficient heat exchange with the flue gas in the exchanger.

[0021] Preferably, the energy-gathering ring body includes an upper plate and a lower plate, the upper plate is connected to the upper end of the lower plate and forms the air flow channel, several smoke inlets are located on the inner side of the upper plate, and several smoke outlets are located on the outer side of the lower plate.

At the same time, the flue gas inlet is arranged on the inner side of the upper plate, and the flue gas outlet is arranged on the outer side of the lower plate. A gap is left between the upper plate and the lower plate, and finally an air flow channel is formed to provide a place for heat exchange.

[0027] A gas stove comprises the energy gathering ring assembly mentioned above.

[0028] In this solution, the gas stove achieves sufficient preheating of the external air by adopting the energy-gathering ring assembly, while reducing damage to the structure of the gas stove itself and increasing the practical life of the gas stove. The smoke generated by the gas stove is not easily discharged to the outside through the energy-gathering ring, thereby avoiding fumigating the user.

[0056] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0057] Example 1

[0058] This embodiment 1 discloses an energy-gathering ring assembly 1, such as Figure 1 As shown, the energy gathering ring assembly 1 includes an energy gathering ring body 11 and an exchanger 12. A plurality of smoke inlets 2 are opened on the inner side of the energy gathering ring body 11, and a plurality of smoke outlets 3 are opened on the outer side of the energy gathering ring body 11. The energy gathering ring body 11 has an air flow channel, and the exchanger 12 is arranged in the air flow channel, and one end of the exchanger 12 is connected to the plurality of smoke inlets 2, and the other end of the exchanger 12 is connected to the plurality of smoke outlets 3. By arranging a smoke inlet 2 on the inner side of the energy gathering ring body 11 and a smoke outlet 3 on the outer side, the smoke can flow in from the smoke inlet 2 and out from the smoke outlet 3, and finally complete the complete heat exchange; secondly, an air flow channel is provided in the energy gathering ring body 11, and the exchanger 12 is placed therein, and the two ends of the exchanger 12 are respectively connected to the smoke inlet 2 and the smoke outlet 3. The air entering the energy gathering ring body 11 can fully contact with the exchanger 12 in the air flow channel and complete sufficient heat exchange with the smoke in the exchanger 12, which can: 1. achieve the purpose of fully preheating the external air, and the preheated air contacts the burner to improve the combustion efficiency; 2. The exchanger 12 is arranged in the energy gathering ring body 11 and does not directly contact the stove, so it is not easy to damage the stove body; 3. The smoke discharged from the energy gathering circle to the outside is less, and it is not easy to smoke the user.

[0059] Specifically, an air inlet 4 and an air outlet 5 are provided on the outer wall of the energy gathering ring assembly 1. The air inlet 4 is located at the upper end of the outer wall of the energy gathering ring body 11, and the air outlet 5 is provided at the lower end of the inner side of the energy gathering ring body 11. The air outlet 5 is close to the burner. Therefore, when the air enters through the air inlet 4, it is fully heat exchanged in the air flow channel in the energy gathering ring body 11 and is discharged through the air outlet 5. The preheated air directly contacts the burner, further improving the combustion efficiency.

[0060] like Figure 2 As shown, the exchanger 12 includes a plurality of annular tubes 121 , which correspond one-to-one to a plurality of flue gas inlets 2 and a plurality of flue gas outlets 3 , and both ends of the annular tubes 121 are connected to the corresponding flue gas inlets 2 and flue gas outlets 3 , respectively. The exchanger 12 is configured as a plurality of annular tubes 121, and the annular tubes 121 are arranged in a surrounding manner in the energy-gathering ring body 11, which firstly saves the space occupied by the installation layout; secondly, the annular arrangement can increase the contact area of the smoke, and maximize the contact between the smoke and the air through multiple layers of surrounding. The annular tubes 121 are respectively connected to the smoke inlet 2 and the smoke outlet 3. The smoke enters the annular tube 121 from the smoke inlet 2, flows into the annular tube 121 from the initial end of the annular tube 121, and finally reaches the end of the annular tube 121 after several layers of surrounding and flows out from the smoke outlet 3, maximizing the contact area of the heat exchange between the smoke and the air, and realizing the whole process from the entry to the discharge of the smoke; thirdly, the exchanger 12 is configured as an annular structure, and the smoke flowing in the tube is not easily discharged to the outside due to the ring shape, so it can avoid fumigating the user.

[0061] Specifically, the outer wall of the annular tube 121 is arranged to separate the flue gas inlet 2 and the flue gas outlet 3, so the outer wall of the annular tube 121 is at a certain distance from the flue gas inlet 2 and the flue gas outlet 3, ensuring that part of the air can enter the air flow channel through this gap. When the flue gas is discharged from the exchanger 12 through the flue gas outlet 3, the external air performs a second heat exchange with it, and once again transfers the heat of the flue gas to the air, reducing heat loss.

[0062] The annular tubes 121 are distributed around the air flow channel. When the external air enters the air flow channel, it contacts the layers of annular tubes 121, and finally achieves sufficient heat exchange and fully preheats the air.

[0063] The material of the exchanger 12 is copper. The exchanger 12 can fully exchange heat between the flue gas and the air. The exchanger 12 is made of copper and has good thermal conductivity.

[0064] The energy-gathering ring body 11 has several flue gas inlets 2 on its inner side and several flue gas outlets 3 on its outer side. The energy-gathering ring body 11 has an insulating cavity within it, and the exchanger 12 is located within the insulating cavity. The insulating cavity is connected to the flue gas inlets 2 and the flue gas outlets 3 to form an air flow channel. The insulating cavity within the energy-gathering ring body 11 can isolate the heat within the cavity from the outside world, preventing heat loss. At the same time, the insulating cavity, the flue gas inlets 2, and the flue gas outlets 3 together form an air flow channel, facilitating the influx of external air and sufficient heat exchange with the flue gas in the exchanger 12.

[0065] like Figure 1 and 2 As shown, the energy-gathering ring body 11 includes an upper plate 111 and a lower plate 112. The upper plate 111 is connected to the upper end of the lower plate 112 and forms an air flow channel. Several smoke inlets 2 are located on the inner side of the upper plate 111, and several smoke outlets 3 are located on the outer side of the lower plate 112. The energy-gathering ring body 11 is configured as an upper plate 111 and a lower plate 112 to facilitate installation and disassembly. At the same time, the smoke inlet 2 is located on the inner side of the upper plate 111, and the smoke outlet 3 is located on the outer side of the lower plate 112. A gap is left between the upper plate 111 and the lower plate 112, ultimately forming an air flow channel and providing a place for heat exchange.

[0066] Specifically, the upper plate 111 has several flue gas inlets 2 on its inclined surface, which connect to the exchanger 12. The exchanger 12 has several copper annular tubes 121 on its upper surface. Several slightly shorter annular tubes 121, perpendicular to the annular tubes 121 and at a certain angle to the horizontal, intersect with these annular tubes 121. These annular tubes 121 are also copper tubes. These slightly shorter annular tubes 121 are connected to the flue gas inlet 2 on the inclined surface of the upper plate 111 and the flue gas outlet 3 on the lower plate 112, respectively. These annular tubes 121 overlap with the circular shapes of the flue gas inlet 2 and flue gas outlet 3. The air inlet 4 on the outside of the lower plate 112 is a long, rectangular hole; the flue gas outlet 3 on the outside of the lower plate 112 is a circular hole, and the air outlet 5 on the inside of the lower plate 112 is a long, rectangular hole.

[0067] like Figure 3 As shown, the lower plate 112 includes a vertical side section 1121, a first horizontal section 1122, a first arc section 1123, a second horizontal section 1124, and a second arc section 1125, which are sequentially connected from the outside to the inside. The flue gas outlet 3 is provided on the vertical side section 1121, and the top of the second arc section 1125 and the vertical side section 1121 respectively abut against the inner and outer ends of the upper plate 111. This configuration allows the lower plate 112 to present a slope from top to bottom. Air entering through the opening of the lower plate 112 will follow this slope from top to bottom, fully contacting the heat exchanger 12, and achieving the purpose of maximum heat exchange.

[0068] Specifically, the air inlet 4 is positioned above the flue gas outlet 3. This slope allows the air to flow downward after entering the energy-gathering ring assembly 1, ensuring contact with the heat exchanger 12. If the flue gas outlet 3 were positioned above the air inlet 4, the air would always flow at a lower level and would not fully contact the heat exchanger 12, effectively achieving sufficient heat exchange. The vertical side segments 1121 may have some angle, and the horizontal segments may include at least two.

[0069] This embodiment 1 also discloses a gas stove comprising the aforementioned energy-gathering ring assembly 1. By employing the energy-gathering ring assembly 1, the gas stove fully preheats the external air, while reducing damage to the gas stove's structure, thereby extending the useful life of the gas stove. Furthermore, smoke generated by the gas stove is not easily discharged from the energy-gathering ring to the outside, thereby preventing smoke from entering the user.

[0070] Specifically, if Figure 4 As shown, the gas stove also includes a burner, an air mixing chamber, an outer ring fire cover, and an inner ring fire cover. In Example 1, an efficiency pot can be installed above the energy-gathering ring assembly 1. When the efficiency pot contacts the upper plate 111 of the energy-gathering ring, there is no gap ("smoke exhaust port"). The smoke after combustion flows completely into the smoke inlet 2 of the upper plate 111 and is discharged through the spiral heat exchanger 12 through a slightly shorter annular tube 121 perpendicular to it. Air flows through the air inlet 4 on the outside of the energy-gathering ring assembly 1, passes through the heat exchanger 12, and flows into the air outlet 5 on the inside of the lower plate 112. The preheated air directly contacts the burner, improving combustion efficiency. The burner's air mixing chamber contacts the inside of the energy-gathering ring assembly 1 in an annular shape, without any gap. The fire hole of the outer ring fire cover is slightly higher than the inside of the energy-gathering ring assembly 1. This arrangement preheats the air, resulting in high combustion efficiency and low smoke. The high-temperature smoke after combustion is cooled by the heat exchanger to a lower temperature, preventing it from causing smoke to humans. A small amount of moisture in the smoke can condense and precipitate.

[0071] Example 2

[0072] The structure of the energy-gathering ring assembly 1 and the gas stove of this embodiment 2 is the same as that of embodiment 1 and will not be repeated. Only the differences will be described. Figure 5As shown, in this embodiment 2, the exchanger 12 further includes a plurality of connecting tubes 122 and a plurality of annular tubes 121. The connecting tubes 122 correspond one-to-one with the plurality of flue gas inlets 2 and the plurality of flue gas outlets 3, and the ends of the connecting tubes 122 are respectively connected to the corresponding flue gas inlets 2 and flue gas outlets 3. The ends of the annular tube 121 are respectively connected to two connecting tubes 122 and communicate with the two connecting tubes 122. The connecting tubes 122 are connected one-to-one with the flue gas inlets 2 and flue gas outlets 3, and the ends of the annular tube 121 are respectively connected to the two connecting tubes 122. Therefore, the connecting tubes 122 penetrate the annular tubes 121, allowing flue gas to flow directly into the annular tubes 121 through one end of the connecting tube 122 and be discharged from the other end of the connecting tube 122 of the annular tube 121. This reduces the large pressure difference in the lumen of the exchanger 12 caused by excessive flue gas, prevents excessive flue gas from accumulating in the lumen, and prevents the lumen from cracking.

[0073] Specifically, the outer wall of the connecting pipe 122 is arranged to separate the flue gas inlet 2 and the flue gas outlet 3, so the outer wall of the connecting pipe 122 is at a certain distance from the flue gas inlet 2 and the flue gas outlet 3, ensuring that part of the air can enter the air flow channel through this gap. When the flue gas flows from the exchanger 12 through the connecting pipe 122 and further discharged through the flue gas outlet 3, at this time, the external air performs a second heat exchange with it, and once again transfers the heat of the flue gas to the air, reducing heat loss.

[0074] The connecting pipe 122 is perpendicular to the annular pipe 121 and is made of copper. The connecting pipe 122 is arranged perpendicular to the annular pipe 121 so that the flue gas can flow directly into the annular pipe 121 smoothly without unnecessary obstruction. At the same time, the copper material has good thermal conductivity.

[0075] The annular tubes 121 are distributed around the air flow channel. When the external air enters the air flow channel, it contacts the layers of annular tubes 121, and finally fully realizes heat exchange and fully preheats the air.

[0076] like Figure 5 As shown, a plurality of upper legs 6 are provided circumferentially on the upper end of the energy focusing ring body 11, and a plurality of lower legs 7 are provided circumferentially on the lower end of the energy focusing ring body 11. The upper legs 6 can support objects on the upper end of the energy focusing ring body 11, improving practicality. At the same time, the lower legs 7 provided circumferentially on the lower end of the energy focusing ring body 11 can support the entire energy focusing ring assembly 1 and provide an upward force.

Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, and such changes and modifications are intended to fall within the scope of the present invention.
