Description

Technical Field

[0001] The invention relates to the field of gas stoves, and in particular to a high-efficiency gas stove. Background Art

[0002] The upper air inlet burner can effectively solve the problem that the lower air inlet burner is easily disturbed by the outside air and goes out. However, the traditional completely upper air inlet burner replenishes the primary air through the gap between the mixing chamber and the base. The problem caused by this is that there is a gap between the mixing chamber and the base. After the mounting screws of the panel are installed, the mounting screws can be seen from the outside of the burner, causing the appearance of the burner to be not beautiful. In addition, after the gap is set between the base and the mixing chamber, the overflow will flow into the base through the gap, which is not only not conducive to the cleaning of the burner, but also if the overflow is not cleared for a long time, it will affect the normal use of the burner. In addition, there is a problem of poor replenishment effect when replenishing the primary air through the above structure, which affects the amount of air ejected by the ejector tube, and then affects the combustion efficiency.

[0003] In addition, in traditional fully upward air inlet burners, secondary air is generally added to the inner ring by opening a secondary air port on the side wall of the mixing chamber, while the source of the secondary air in the outer ring is directly the air around the outer ring fire holes. The secondary air addition effect is poor, which affects the combustion efficiency of both the inner and outer rings. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a high-efficiency gas stove with high combustion efficiency in view of the prior art.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: a high-efficiency gas stove, including a stove panel, a burner and an ejector pipe, the stove panel is provided with a mounting hole, the burner is embedded in the mounting hole, and the ejector pipe is installed below the stove panel, characterized in that it also includes an energy focusing hood arranged on the stove panel, the energy focusing hood is annular and surrounds the outer periphery of the burner, an air inlet is formed on the side wall of the energy focusing hood, an air ring channel is formed circumferentially inside the energy focusing hood, the air ring channel is communicated with the air inlet and downwardly communicated with the air inlet of the ejector pipe.

[0006] Preferably, the burner includes an air mixing chamber, an inner ring fire cover and an outer ring fire cover located above the cooker panel, the air mixing chamber has an annular cavity and a concave cavity opening upward, the annular cavity is arranged around the outer periphery of the concave cavity, and a secondary air annular channel is formed between the two, the outer ring fire cover and the inner ring fire cover are respectively covered on the annular cavity and the concave cavity, and the side wall of the air mixing chamber is provided with secondary air ports communicating with the secondary air annular channel at intervals along the circumferential direction, and the air annular channel is communicated with the secondary air ports. In this way, the air annular channel can not only replenish primary air to the ejector tube, but also replenish secondary air to the inner ring, and the secondary air is preheated by the energy focusing cover, so that it can participate in the combustion of the inner ring fire more efficiently.

[0007] Furthermore, preferably, an outer ring fire outlet hole is provided on the outer ring fire cover, and the air ring channel is communicated with the outer ring fire outlet hole. It can be seen that the air ring channel can simultaneously supplement secondary air to the outer ring on the basis of supplementing primary air to the ejector tube and supplementing secondary air to the inner ring, and the secondary air is also preheated by the energy focusing cover, so as to better participate in the combustion of the outer ring fire.

[0008] The air ring channel can be communicated with the secondary air ring channel and the outer ring fire outlet hole in various ways. Preferably, the inner wall of the energy focusing cover is provided with a secondary air outlet communicated with the air ring channel, and the secondary air outlet is communicated with the secondary air outlet and the outer ring fire outlet hole. This not only has a simple structure and is convenient for processing, but also enables the air ring channel to be better communicated with the secondary air ring channel and the outer ring fire outlet hole.

[0009] In order to enable the secondary air outlets to better replenish secondary air to the secondary air loop, preferably, the number of the secondary air outlets matches and corresponds one to one with the secondary air ports, and each secondary air outlet is opposite to the corresponding secondary air port.

[0010] Preferably, the inner side wall of the energy gathering cover extends inwardly along the circumferential direction to form an air guide ring edge, which is arranged in a sunken manner relative to the top edge of the energy gathering cover and is opposite to the outer ring fire outlet hole, and a secondary air gap communicating with the secondary air port is formed between the air guide ring edge and the outer ring fire cover, and the secondary air gap is communicated with the outer ring fire outlet hole. The air in the air ring channel can be better guided to the outer ring fire outlet hole through the air guide ring edge, so as to supplement the outer ring fire outlet hole with secondary air, and the top surface of the air guide ring edge is lower than the top edge of the energy gathering cover, so as to receive the overflow generated during the cooking process and prevent the overflow from affecting the combustion.

[0011] In order to allow the outside air to enter the air annular channel better, preferably, the air inlets are arranged on the outer side wall of the energy collecting cover at intervals along the circumferential direction.

[0012] In order to allow the air in the air ring to be better introduced into the interior of the gas stove and replenish the primary air for the ejector tube, preferably, the bottom of the energy focusing hood is provided with primary air outlets spaced circumferentially, and the primary air outlets are communicated with the above-mentioned air ring; the stove panel is provided with air intake openings, which correspond to the above-mentioned primary air outlets one by one and match them respectively, and the side edges of each primary air outlet are overlapped with the side edges of the corresponding air intake openings.

[0013] Preferably, the energy collecting cover is a split structure, including an annular upper cover and an annular base, the upper cover is formed with an upper annular groove opening downward along the circumference, the base is formed with a lower annular groove opening upward along the circumference, the upper and lower annular grooves are assembled to form the air annular channel. This not only facilitates the processing and manufacturing of the energy collecting cover, but also facilitates the cleaning of the inside of the energy collecting cover.

[0014] Preferably, pot feet are arranged at intervals along the circumferential direction on the top of the upper cover, so that the energy focusing cover can also serve as a pot support.

[0015] Compared with the prior art, the advantages of the present invention are: an energy-gathering hood is provided on the outer periphery of the burner in the present invention, thereby reducing the loss of heat generated by the burner, and an air ring channel is formed in the energy-gathering hood, through which air can be replenished to the air inlet of the ejector tube, so that the ejector tube can inject sufficient air into the burner to ensure sufficient combustion of the gas, thereby improving the combustion efficiency of the stove; in addition, the air is preheated after entering the air ring channel, so that the energy of the air molecules jumps and the activity is enhanced, which not only enables the air molecules to be quickly and fully mixed with the gas molecules, but also generates a certain suction force at the air inlet, which is conducive to replenishing more air into the air ring channel, further improving the combustion efficiency.

[0024] The present invention is further described in detail below with reference to the accompanying drawings.

[0025] like Figures 1 to 8 As shown, a high-efficiency gas stove comprises a stove panel 1, a burner 2 and an ejector pipe 4. A circular mounting hole 11 is provided on the stove panel 1, and the burner 2 is embedded in the mounting hole 11. The ejector pipe 4 is installed below the stove panel 1, that is, the ejector pipe 4 is installed in the inner cavity of the gas stove. In addition, a nozzle 5 matching the ejector pipe 4 is also installed in the inner cavity of the gas stove.

[0026] The burner 2 includes an air mixing chamber 23, an inner fire ring cover 22 and an outer fire ring cover 21 located above the cooker panel 1. The air mixing chamber 23 has an upwardly open annular cavity 231 and a concave cavity 232. The annular cavity 231 is arranged around the outer periphery of the concave cavity 232, and a secondary air annular channel 24 is formed therebetween. The outer fire ring cover 21 and the inner fire ring cover 22 are respectively covered on the annular cavity 231 and the concave cavity 232. Secondary air ports 233 communicating with the secondary air annular channel 24 are provided on the side walls of the air mixing chamber 23 at intervals along the circumferential direction.

[0027] The cooker panel 1 is also provided with a gathering hood 3, which is annular and surrounds the outer periphery of the burner 2. Four air inlets 33 are arranged at intervals along the circumferential direction on the outer wall of the gathering hood 3. An air ring 30 is formed circumferentially inside the gathering hood 3. The air ring 30 is communicated with each of the air inlets 33, and downwardly communicated with the air inlet 41 of the ejector tube 4. It can be seen that the gathering hood 3 is arranged around the outer periphery of the burner 2, so that the loss of heat generated by the burner 2 can be reduced, and the gathering hood 3 is formed with an air ring 30, through which primary air can be supplemented to the air inlet 41 of the ejector tube 4, so that the ejector tube 4 can inject enough air into the burner 2, so as to ensure the full combustion of the gas, thereby improving the combustion efficiency of the cooker. In addition, the air is preheated after entering the air ring 30, so that the energy of the air molecules jumps and the activity is enhanced, so that it can be mixed with the gas molecules more quickly and fully, further improving the combustion efficiency.

[0028] Specifically, in this embodiment, the energy collecting cover 3 is a split structure, including an annular upper cover 31 and an annular base 32. An upper annular groove 310 opening downward is formed on the upper cover 31 along the circumference, and a lower annular groove 320 opening upward is formed on the base 32 along the circumference. The upper and lower annular grooves 310 and 320 are assembled to form the air annular channel 30. Among them, four grooves 321 are arranged axially at intervals on the top edge of the outer groove wall of the lower annular groove 320, and each groove 321 is assembled with the bottom edge of the outer groove wall of the upper annular groove 310 to form the air inlet 33. The energy collecting cover 3 is a split structure, which is not only convenient for the processing and manufacturing of the energy collecting cover 3, but also convenient for cleaning the inside of the energy collecting cover 3.

[0029] Four primary air outlets 36 are arranged at intervals along the circumferential direction on the bottom wall of the lower annular groove 320, and four air inlet openings 12 are opened along the circumferential direction at the corresponding part of the cooker panel 1 with the center of the mounting hole 11 as the center. The air inlet openings 12 correspond to and match the primary air outlets 36 one by one, and the side edges of each primary air outlet 36 overlap with the side edges of the corresponding air inlet openings 12. That is, the air entering the air annular channel 30 from the air inlet 33 passes through the primary air outlets 36 and the corresponding air inlet openings 12 in turn and enters the inner cavity of the gas stove, thereby replenishing the primary air for the injection of the ejector pipe 4. In addition, the air entering the air annular channel 30 stays in the air annular channel 30, and the heat generated by the burner 2 is transferred to the energy collecting cover 3 to preheat the air in the air annular channel 30. The energy of the preheated air molecules jumps, and the activity is enhanced. After flowing to the air inlet 41 of the ejector pipe 4, it can be fully mixed with the gas injected by the nozzle 5.

[0030] In addition to supplying primary air to the ejector tube 4 through the primary air outlet 36, the air annular channel 30 in this embodiment can also supply secondary air to the outer ring fire outlet 211 on the outer ring fire cover 21 and the secondary air annular channel 24. That is, the same channel (the air annular channel 30) can simultaneously supply primary air to the ejector tube 4 and supply secondary air to the inner and outer ring fire covers 22 and 21, respectively, making the structure of the burner compact.

[0031] Specifically, the bottom end of the inner groove wall of the lower annular groove 320 is provided with secondary air outlets 37 at intervals along the circumferential direction, and each secondary air outlet 37 extends along the length direction of the inner groove wall. In this embodiment, there are four secondary air outlets 37, and the corresponding number of the secondary air ports 233 is also four, and each secondary air outlet 37 corresponds to each secondary air port 233 one by one and is respectively opposite to each other. Thus, the secondary air outlets 37 can better replenish the secondary air to the secondary air annular channel 24.

[0032] In this embodiment, the inner side wall of the upper cover 31 extends horizontally inward along the circumferential direction to form an air guide ring edge 34, which is arranged around the outer circumference of the outer ring fire cover 21 and opposite to the outer ring fire outlet 211 of the outer ring fire cover 21, and a secondary air gap 35 communicating with the secondary air port 233 is formed between the air guide ring edge 34 and the outer ring fire cover 21, and the secondary air gap 35 is communicated with the outer ring fire outlet 211. The air in the air annular channel 30 can be better guided to the outer ring fire outlet 211 through the air guide ring edge 34, so as to supplement the secondary air for the outer ring fire outlet 211. In addition, in this embodiment, the air guide ring edge 34 is arranged in a sunken manner relative to the top edge of the upper cover 31, that is, the height of the air guide ring edge 34 is lower than the top edge of the upper cover 31, so that the top surface of the air guide ring edge 34 can receive the overflow generated during the cooking process.

[0033] Furthermore, four pot feet 311 are provided at intervals along the circumferential direction on the top of the upper cover 31 , and each pot foot 311 extends horizontally radially inward relative to the upper cover 31 . The pot feet 311 can enable the energy collecting cover 3 to also serve as a pot support.
