Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to an infrared burner and an infrared gas stove. Background Art

[0002] The existing infrared gas stoves only have two rings of fire, namely the inner ring and the outer ring. Among them, the area of the outer ring fire disc is relatively large. When the heat intensity of the fire holes is low, since the infrared gas stove generally does not have stable flame fire holes, it will cause uneven distribution of the outer ring flame, and some of the outer ring fire holes cannot generate flames. When the heat intensity of the fire holes is high, the outer ring flame can achieve a relatively uniform distribution effect, but the large heat intensity of the fire holes will cause the infrared gas stove to have flashback (the infrared gas stove is more prone to flashback than the atmospheric stove).

[0003] Therefore, there is an urgent need for an infrared burner to solve the above problems. Content of the Utility Model

[0035] The following embodiments illustrate the present utility model, but the present utility model is not limited by these embodiments. Modifying the specific implementation manner of the present utility model or equivalently replacing some technical features without departing from the spirit of the solution of the present utility model shall all be covered within the scope of the technical solution claimed by the present utility model.

[0036] Please refer to Figures 1 - 3 , the present utility model provides an infrared burner, which includes a burner body (not shown in the figure) and a cock valve 1. An inner-ring fire gas channel, a middle-ring fire gas channel arranged outside the inner-ring fire gas channel, and an outer-ring fire gas channel arranged outside the middle-ring fire gas channel are provided on the burner body. The cock valve 1 includes a valve seat 11 and a valve core 12. A valve cavity 100 is arranged in the valve seat 11. A first air inlet hole, a first inner-ring air outlet hole 1011, a first middle-ring air outlet hole 1021, and a first outer-ring air outlet hole 1031 that communicate the valve cavity 100 with the outside of the valve seat 11 are opened on the valve seat 11. The valve core 12 is arranged in the valve cavity 100. An air passage cavity 200 is arranged in the valve core 12. A second air inlet hole, a second inner-ring air outlet hole 1012, a second middle-ring air outlet hole 1022, and a second outer-ring air outlet hole 1032 are opened on the inner wall of the air passage cavity 200. The second air inlet hole and the first air inlet hole communicate to form an air inlet passage. The second inner-ring air outlet hole 1012 and the first inner-ring air outlet hole 1011 correspond to form an inner-ring air outlet passage. The second middle-ring air outlet hole 1022 and the first middle-ring air outlet hole 1021 correspond to form a middle-ring air outlet passage. The second outer-ring air outlet hole 1032 and the first outer-ring air outlet hole 1031 correspond to form an outer-ring air outlet passage. The inner-ring air outlet passage communicates with the inner-ring fire gas channel. The middle-ring air outlet passage communicates with the middle-ring fire gas channel. The outer-ring air outlet passage communicates with the outer-ring fire gas channel.

[0037] The infrared burner provided by the present utility model forms an inner-ring, middle-ring, and outer-ring three-ring fire by providing an inner-ring fire gas channel, a middle-ring fire gas channel, and an outer-ring fire gas channel on the burner body and setting a corresponding cock valve 1, and setting an inner-ring air outlet passage corresponding to the inner-ring fire gas channel, a middle-ring air outlet passage corresponding to the middle-ring fire gas channel, and an outer-ring air outlet passage corresponding to the outer-ring fire gas channel on the cock valve 1. Compared with the existing infrared burner with only an inner-ring and an outer-ring two-ring fire, it can adjust the firepower more carefully and precisely, which is beneficial to adjusting the firepower of each combustion gear of the burner into a stepped and uniform distribution form, facilitating the user to adjust the firepower size. It can also effectively improve the problem that the heat intensity of the fire holes in the outer ring of the existing burner with only two-ring fire is low due to the too large area of the outer ring, resulting in unstable combustion of the outer-ring fire. The user experience is good.

[0038] Optionally, the second inner-ring air outlet hole 1012 is formed at the bottom of the ventilation cavity 200, and the first inner-ring air outlet hole 1011 is formed at the lower part of the valve seat 11 and is located below the second inner-ring air outlet hole 1012. So that the valve core 12 does not block the first inner-ring air outlet hole 1011, and thus the firepower of the inner-ring fire only has one gear.

[0039] Optionally, both the second middle-ring air outlet hole 1022 and the second air inlet hole are arranged lower than the second outer-ring air outlet hole 1032. So that when the plug 14 slides relative to the ventilation cavity 200 from top to bottom, only the second outer-ring air outlet hole 1032 will be blocked, and the second middle-ring air outlet hole 1022 and the second air inlet hole will not be blocked, affecting the air outlet of the middle-ring air outlet channel and the air inlet of the air inlet channel.

[0040] Optionally, it further includes a valve rod 13 arranged in the vertical direction. The upper part of the valve rod 13 extends out of the valve seat 11 and is slidably connected to the valve seat 11. The lower part of the valve rod 13 is slidably connected to the valve core 12. The valve rod 13 can simultaneously slide between a first position and a second position in the vertical direction relative to the valve core 12 and the valve seat 11. A slot structure is arranged at the connection between the lower part of the valve rod 13 and the valve core 12 in the vertical direction. The valve rod 13 can slide in the vertical direction along the slot structure and drive the valve core 12 to rotate in the horizontal direction through the slot structure, so as to adjust the size of the middle-ring air outlet channel and / or the outer-ring air outlet channel, and thus adjust the air outlet volume of the middle-ring air outlet channel and the outer-ring air outlet channel.

[0041] Specifically, the slot structure includes a sliding groove and a sliding block. The sliding groove is arranged on one of the valve rod 13 and the valve core 12 in the vertical direction, and the sliding block is arranged on the other of the valve rod 13 and the valve core 12. The sliding block extends into the sliding groove and can slide along the sliding groove.

[0042] Since the combustion area of the infrared burner is larger than that of the ordinary atmospheric burner, the flame transfer distance of the infrared burner is also longer than that of the atmospheric burner. Therefore, during the hot ignition operation of the infrared gas stove, since the ignition point is in the inner ring and there is a considerable distance from the outer ring, when the flame is transferred to the outer ring along with the ignition point, it takes about 0.5 s. During this time, the inner and outer rings supply gas simultaneously. When the inner ring meets the combustion conditions and the flame is transferred to the outer ring after another 0.5 s, the gas concentration in the outer ring is already in an excessive state, which leads to deflagration of the outer ring flame. Therefore, in this embodiment, optionally, a plug 14 is further included. The plug 14 is arranged on the lower side of the valve stem 13 and is located in the air vent cavity 200. When the valve stem 13 is in the first position, the valve stem 13 pushes the plug 14 to move to the third position. When the valve stem 13 is in the second position, the valve stem 13 pulls the plug 14 to move to the fourth position. When the plug 14 is in the third position, the plug 14 blocks part or all of the second outer ring air outlet holes 1032. When the plug 14 is in the fourth position, the plug 14 opens the second outer ring air outlet holes 1032. By arranging the plug 14 on the lower side of the valve stem 13, when the valve stem 13 is pressed down by the user to the first position for ignition operation, the plug 14 can move downward to the second outer ring air outlet holes 1032 to partially block the second outer ring air outlet holes 1032, thereby reducing the gas discharged from the air vent cavity 200 to the outer ring flame gas passage during ignition, so that the outer ring flame does not deflagrate. Or the plug 14 can move downward to the second outer ring air outlet holes 1032 to completely block the second outer ring air outlet holes 1032, so that no gas can be discharged from the air vent cavity 200 to the outer ring flame gas passage during ignition, and thus the outer ring flame does not deflagrate. When the valve stem 13 is released and the ignition is successful, the gas in the air vent cavity 200 will be delivered to the outer ring flame gas passage in a preset amount to achieve normal combustion.

[0043] Optionally, a plug 14 and a return spring 16 are further included. The plug 14 is separately arranged from the valve stem 13. A first limit step 141 is arranged on the outer side of the plug 14, and a second limit step 201 located below the first limit step 141 is arranged on the inner wall of the air vent cavity 200. The return spring 16 is sleeved on the outer side of the plug 14 and is located between the first limit step 141 and the second limit step 201. The valve stem 13 can drive the plug 14 to slide from the fourth position to the third position when being pressed down, at this time the return spring 16 is in a contracted state. When the valve stem 13 is released, the plug 14 can be reset to the fourth position under the elastic force of the return spring 16.

[0044] Optionally, a third limit step 202 is further arranged on the inner wall of the air vent cavity 200. When the plug 14 is in the third position, the lower end of the plug 14 abuts against the upper end of the third limit step 202 to limit the downward travel of the plug 14.

[0045] Optionally, it further includes a first sealing ring 17. The first sealing ring 17 is sleeved outside the plug 14 and abuts against the inner wall of the ventilation cavity 200. The first sealing ring 17 is located above the second outer-ring air outlet hole 1032 to prevent the gas in the ventilation cavity 200 from leaking through the gap between the plug 14 and the inner wall of the ventilation cavity 200.

[0046] Optionally, it further includes a second sealing ring 15. The second sealing ring 15 is sleeved outside the plug 14 and abuts against the inner wall of the ventilation cavity 200. When the plug 14 is in the third position, the second sealing ring 15 is located below the second outer-ring air outlet hole 1032, so that the gas in the ventilation cavity 200 will not flow into the second outer-ring air outlet hole 1032, thereby further improving the full-blocking effect on the second outer-ring air outlet hole 1032.

[0047] Optionally, it further includes an air inlet part 184, an inner-ring air outlet part 181, a middle-ring air outlet part 182, an outer-ring air outlet part 183 and a stir-fry solenoid valve 2. The air inlet part 184 is arranged outside the valve seat 11 and communicated with the air inlet channel. The inner-ring air outlet part 181 is arranged outside the valve seat 11 and communicated with the inner-ring air outlet channel. The middle-ring air outlet part 182 is arranged outside the valve seat 11 and communicated with the middle-ring air outlet channel. The outer-ring air outlet part 183 is arranged outside the valve seat 11 and communicated with the outer-ring air outlet channel. The stir-fry solenoid valve 2 is installed on the outer-ring air outlet part 183.

[0048] Optionally, it further includes an inner-ring nozzle 1811, a middle-ring nozzle 1821 and an outer-ring nozzle 1831. The inner-ring nozzle 1811 is installed at one end of the inner-ring air outlet part 181 far away from the valve seat 11. The middle-ring nozzle 1821 is installed at one end of the middle-ring air outlet part 182 far away from the valve seat 11. The outer-ring nozzle 1831 is installed at one end of the outer-ring air outlet part 183 far away from the valve seat 11.

[0049] Optionally, the solenoid valve includes a valve body part 21 and a connecting part 22 which are connected to each other. The connecting part 22 is arranged at the front part of the valve body part 21 and connected to the outer-ring air outlet part 183. In this way, the valve body part 21 is arranged on the side close to the cock valve 1, reducing the high-temperature influence of the burner on the solenoid valve and being beneficial to ensuring the service life of the solenoid valve.

[0050] On the other hand, the present utility model provides an infrared gas stove, including the above-mentioned infrared burner.

[0051] Optionally, the infrared gas stove includes a first-stage combustion load W1, a second-stage combustion load W2, a third-stage combustion load W3, a fourth-stage combustion load W4, and a fifth-stage combustion load W5, where W1 < W2 < W3 < W4 < W5.

When the infrared gas stove operates at the first-stage combustion load W1, both the middle-ring gas outlet channel and the outer-ring gas outlet channel are closed, and the gas flow rate in the inner-ring gas outlet channel operates at the first gas flow rate gear L1; when the infrared gas stove operates at the second-stage combustion load W2, the outer-ring gas outlet channel is closed, the gas flow rate in the inner-ring gas outlet channel operates at the first gas flow rate gear L1, and the gas flow rate in the middle-ring gas outlet channel operates at the third gas flow rate gear L3; when the infrared gas stove operates at the third-stage combustion load W3, the gas flow rate in the outer-ring gas outlet channel operates at the fourth gas flow rate gear L4, the gas flow rate in the middle-ring gas outlet channel operates at the second gas flow rate gear L2, and the gas flow rate in the inner-ring gas outlet channel operates at the first gas flow rate gear L1; when the infrared gas stove operates at the fourth-stage combustion load W4, the gas flow rate in the outer-ring gas outlet channel operates at the fifth gas flow rate gear L5, the gas flow rate in the middle-ring gas outlet channel operates at the third gas flow rate gear L3, and the gas flow rate in the inner-ring gas outlet channel operates at the first gas flow rate gear L1; when the infrared gas stove operates at the fifth-stage combustion load W5, the gas flow rate in the outer-ring gas outlet channel operates at the sixth gas flow rate gear L6, the gas flow rate in the middle-ring gas outlet channel operates at the third gas flow rate gear L3, and the gas flow rate in the inner-ring gas outlet channel operates at the first gas flow rate gear L1. In this way, a stepped and uniform distribution of the firepower of the infrared gas stove at each gear is achieved.

[0052] The above are only some embodiments of the present invention.
