Description

Technical Field

[0001] The present application belongs to the technical field of kitchen and bathroom appliances, and specifically relates to a gas distribution plate and a burner. Background Art

[0002] A gas stove is a device that burns gas to generate heat. During the combustion process, both primary and secondary air are required. When the secondary air level is too low, combustion is incomplete, which can lead to oxygen deprivation. When the secondary air level is too high, excess air consumes the heat generated by combustion, resulting in low combustion efficiency.

[0003] For common burners with air distribution plates, there is a phenomenon that the amount of secondary air in the inner ring cavity is excessive and the amount of secondary air in the outer ring cavity is too small, which leads to a technical problem of poor combustion condition of the burner. Summary of the Invention

The guide is arranged on the travel path of the secondary air introduced through the outer ring air intake channel to change the travel path of the secondary air.

[0010] The present application provides an air distribution plate, which has an outer ring air inlet channel provided on the circumference of the outer ring cavity of the air distribution plate, and an inner ring cavity gap provided on the inner side of the outer ring cavity. Secondary air can be introduced into the space between the outer ring cavity and the inner ring cavity through the outer ring air inlet channel to introduce secondary air into the inner part of the outer ring cavity. Since the inner ring air inlet channel and the guide are provided on the circumference of the inner ring cavity, the inner ring air inlet channel and the outer ring air inlet channel are communicated, and the guide is provided on the travel path of the secondary air introduced through the outer ring air inlet channel. Under the guidance of the guide, the secondary air introduced through the outer ring air inlet channel needs to flow laterally before it can enter the inner ring cavity through the inner ring air inlet channel, thereby reducing the amount of secondary air replenished in the inner ring cavity and increasing the amount of secondary air replenished in the outer ring cavity to improve the combustion condition of the burner.

[0011] In some embodiments, the outer ring air inlet channel is arranged along the radial direction of the outer ring cavity, and the guide member is arranged along the radial direction of the inner ring cavity. The center lines of the outer ring air inlet channel and the guide member are located on the same straight line, which can minimize the amount of secondary air supplemented to the inner ring cavity and enhance the amount of secondary air supplemented in the outer ring cavity.

[0012] In some embodiments, the outer ring air intake channel and the inner ring air intake channel are each provided with multiple corresponding intervals, and two adjacent inner ring air intake channels are separated by the guide member to improve the balance of the secondary air replenishment amount in the inner ring cavity and the outer ring cavity.

[0014] As a preferred solution of the present application, the outer ring cavity is fixedly connected to the body, and the inner ring cavity is rotatably connected to the body.

[0015] In some embodiments, a first sliding member is provided at the bottom of the inner ring cavity, and a second sliding member is provided on the body. The first sliding member can cooperate with the second sliding member to rotate the inner ring cavity to a set angle on the body.

[0016] In some embodiments, the first sliding member is one of a sliding groove and a limiting column provided at the bottom of the inner ring cavity;

[0017] The second sliding member is the other of the sliding groove and the limiting column provided on the body;

[0018] Wherein, the limiting column can be cooperatively arranged in the sliding groove.

[0019] In some embodiments, the set angle is half of the angle between the center lines of two adjacent inner ring air inlet passages.

[0020] In some embodiments, a plurality of first connecting holes are provided at the bottom of the inner ring cavity, a plurality of second connecting holes and a plurality of third connecting holes are provided on the main body, the second connecting holes and the third connecting holes are arranged alternately, and the first connecting holes can be selectively matched with the second connecting holes or the third connecting holes to fix the inner ring cavity on the main body.

[0021] On the other hand, the present application provides a burner, which is special in that the burner includes the above-mentioned gas distribution plate.

[0039] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0040] Figure 1 This is a structural diagram of a gas distributor designed during the applicant's research and development process. Figure 2 for Figure 1 Schematic cross-section diagram, combined with Figure 1 as well as Figure 2 The air distribution plate includes a main body 100, an outer ring cavity 200 and an inner ring cavity 300, wherein the outer ring cavity 200 and the inner ring cavity 300 are both arranged on the main body 100, and the inner ring cavity 300 is gap-arranged in the outer ring cavity 200. An outer ring air intake channel 201 is arranged on the circumferential surface of the outer ring cavity 200, and an inner ring air intake channel 301 is arranged on the circumferential surface of the inner ring cavity 300. The center lines of the outer ring air intake channel 201 and the inner ring air intake channel 301 are located on the same straight line, that is, the outer ring air intake channel 201 and the inner ring air intake channel 301 are arranged relative to each other. After the secondary air flows into the outer ring air intake channel 201, it can directly flow into the inner ring cavity 300 through the inner ring air intake channel 301, thereby resulting in excessive secondary air supplement in the inner ring cavity 300, and too little secondary air in the outer ring cavity 200, resulting in poor combustion conditions.

[0041] Based on the above technical problems, an embodiment of the present application provides a gas distribution plate and a burner, aiming to improve the technical problem of poor combustion conditions of the burner to at least a certain extent.

[0042] First, the present application provides a gas distribution plate.

[0043] Figure 3 This is a structural diagram of a gas distribution plate according to an embodiment of the present application. Figure 4 for Figure 3 Schematic cross-section of the . Figure 3 as well as Figure 4 The air distribution disk of the embodiment of the present application includes a main body 100, an outer ring cavity 200 and an inner ring cavity 300, wherein the outer ring cavity 200 and the inner ring cavity 300 are both arranged on the main body 100, the inner ring cavity 300 gap is arranged on the inner side of the outer ring cavity 200, and an outer ring air inlet channel 201 is arranged on the circumferential surface of the outer ring cavity 200 to introduce secondary air between the outer ring cavity 200 and the inner ring cavity 300. The inner ring air inlet channel 301 and a guide 302 are arranged on the circumferential surface of the inner ring cavity 300, the inner ring air inlet channel 301 and the outer ring air inlet channel 201 are communicated, and the guide 302 is arranged on the travel path of the secondary air introduced through the outer ring air inlet channel 201 to change the travel path of the secondary air.

[0044] The embodiment of the present application provides an air distribution plate. Since the outer ring cavity 200 of the air distribution plate is provided with an outer ring air inlet channel 201 on the circumference thereof, and the inner ring cavity 300 gap is provided on the inner side of the outer ring cavity 200, secondary air can be introduced into the space between the outer ring cavity 200 and the inner ring cavity 300 through the outer ring air inlet channel 201 to introduce secondary air into the interior of the outer ring cavity 200. Since the inner ring air inlet channel 301 and the guide member 302 are provided on the circumference of the inner ring cavity 300, the inner ring air inlet channel 301 is communicated with the outer ring air intake channel 201, and the guide member 302 is arranged on the travel path of the secondary air introduced through the outer ring air intake channel 201. Under the guidance of the guide member 302, the secondary air introduced through the outer ring air intake channel 201 needs to flow laterally to pass through the inner ring air intake channel 301 and enter the inner ring cavity 300, thereby reducing the amount of secondary air supplemented to the inner ring cavity 300 and increasing the amount of secondary air supplemented in the outer ring cavity 200 to improve the combustion condition of the burner.

[0045] Combine Figure 3 as well as Figure 4 The outer ring air intake channel 201 of the embodiment of the present application can be arranged along the radial direction of the outer ring cavity 200, and the guide member 302 can also be arranged along the radial direction of the inner ring cavity 300, and the center lines of the outer ring air intake channel 201 and the guide member 302 are located on the same straight line, that is, the outer ring air intake channel 201 and the guide member 302 are arranged relative to each other, and the secondary air introduced through the outer ring air intake channel 201 is evenly divided into two streams under the guidance of the guide member 302. The two streams of secondary air bypass the corresponding guide members 302 respectively, and then enter the inner ring cavity 300 through the inner ring air intake channel 301. It can not only minimize the amount of secondary air replenishing the inner ring cavity 300 and enhance the amount of secondary air replenishing the outer ring cavity 200, but also improve the balance of the secondary air entering the inner ring cavity 300 and improve the combustion effect.

[0046] Of course, the guide member 302 may also be only partially located on the path of the secondary air introduced through the outer ring air inlet channel 201, which can also achieve the technical purpose of reducing the amount of secondary air added to the inner ring cavity 300 and increasing the amount of secondary air added to the outer ring cavity 200.

[0047] Combine Figure 3 as well as Figure 4 In the embodiment of the present application, multiple outer ring air intake channels 201 and inner ring air intake channels 301 are arranged at corresponding intervals. The multiple outer ring air intake channels 201 and inner ring air intake channels 301 arranged at intervals can improve the balance of the secondary air replenishment amount in the inner ring cavity 300 and the outer ring cavity 200.

[0048] Combine Figure 3 as well as Figure 4In the case where a plurality of outer ring air intake channels 201 and inner ring air intake channels 301 are arranged at intervals, two adjacent inner ring air intake channels 301 are separated by a guide member 302, that is, the partition member between the two adjacent inner ring air intake channels 301 can be configured as a guide member 302.

[0049] Combine Figure 3 as well as Figure 4 In an embodiment of the present application, the outer ring air inlet channel 201, the inner ring air inlet channel 301 and the guide member 302 can all be fan-shaped. Preferably, the outer ring air inlet channel 201 and the relative guide member 302 have the same central angle to improve the balance of the secondary air replenishment amount in the inner ring cavity 300 and the outer ring cavity 200.

Figure 6 for Figure 3 Schematic diagram of the structure in which the outer ring cavity is assembled on the body, Figure 7 for Figure 6 The top view, combined with Figure 3 、 Figure 5 、 Figure 6 as well as Figure 7 In the embodiment of the present application, a through hole 101 and a stopper 102 are provided in the middle of the body 100. The stopper 102 is provided at the edge of the through hole 101. The outer ring cavity 200 includes a first ring sleeve 202 and a second ring sleeve 203 provided on the body 100. The first ring sleeve 202 is coaxially provided on the outside of the through hole 101 to support the inner ring of the outer ring fire cover 400. The second ring sleeve 203 is provided on the outside of the first ring sleeve 201 to support the outer ring of the outer ring fire cover 400. 3 can be connected through the first draft member 204, and the first draft member 204 is provided with the outer ring air inlet channel 201. The secondary air located on the outside of the second ring sleeve 203 can be introduced into the inside of the first ring sleeve 202 through the outer ring air inlet channel 201, so as to supply the secondary air to the inside of the outer ring fire cover 400 and the outside of the inner ring fire cover 500, and the primary air and fuel gas can be supplemented to the inside of the outer ring fire cover 400 through the gap between the adjacent first draft members 204 for combustion of the outer ring fire cover 400.

[0051] In the embodiment of the present application, the inner ring cavity 300 and the outer ring cavity 200 can rotate relative to each other, so that the applicant's products in the research and development process can be quickly modified to produce a gas distribution plate that meets the technical solution of the present application.

[0052] Figure 8 for Figure 3 Schematic diagram of the structure of the inner ring cavity, Figure 9 for Figure 8 Schematic diagram of the top view, combined with Figure 3 、 Figure 4 、 Figure 5 、 Figure 8 as well as Figure 9 The inner ring cavity 300 of the embodiment of the present application includes a bottom plate 303 and a third ring sleeve 304 and a fourth ring sleeve 305 arranged on the bottom plate 303. The bottom plate 303 is supported in the stop 102 of the body 100. The third ring sleeve 304 is coaxially arranged on the bottom plate 303 to support the inner ring of the inner ring fire cover 500. The fourth ring sleeve 305 is gap-arranged on the outside of the third ring sleeve 304 to support the outer ring of the inner ring fire cover 500. The inner ring fire cover 500 and the outer ring fire cover 500 can be connected through the second air inlet member 306, and the second air inlet member 306 is provided with the inner ring air inlet channel 301. The secondary air entering the outer ring cavity 200 through the outer ring air inlet channel 201 can be introduced into the inner side of the third ring sleeve 304 through the inner ring air inlet channel 301 to supply the secondary air to the inner side of the inner ring fire cover 500, and the primary air and fuel gas can be supplemented to the interior of the inner ring fire cover 500 through the inner ring cavity 300 for the combustion of the inner ring fire cover 500.

[0053] As a preferred solution of the present application, the outer ring cavity 200 of the embodiment of the present application can be fixedly connected to the main body 100, preferably formed as one piece, while the inner ring cavity 300 and the main body 100 are a split structure, and the inner ring cavity 300 can be rotatably connected to the main body 100. By controlling the rotation of the inner ring cavity 300 on the main body 100, the guide 302 of the inner ring cavity 300 can be set at a relative position of the outer ring air inlet channel 201.

[0054] In some embodiments, a first sliding member 307 can be provided at the bottom of the inner ring cavity 300, and a second sliding member 103 can be provided on the main body 100. The first sliding member 307 can cooperate with the second sliding member 103 to rotate the inner ring cavity 300 to a set angle on the main body 100.

[0055] Furthermore, the first sliding member 307 can be one of the sliding groove and the limiting column arranged at the bottom of the inner ring cavity 300, and the second sliding member 103 can be the other of the sliding groove and the limiting column arranged on the main body 100. The limiting column can be cooperatively arranged in the sliding groove to control the inner ring cavity 300 to rotate on the main body 100. The limiting column can slide in the sliding groove. When the limiting column slides to the end of the sliding groove, the inner ring cavity 300 rotates to the set angle on the main body 100, and the preliminary positioning of the inner ring cavity 300 and the main body 100 is completed. Then the inner ring cavity 300 can be fixed to the main body 100 by bolts or pins.

[0056] For the embodiment of the present application, the bottom of the base plate 303 may be provided with the sliding groove, and the stop 102 of the main body 100 may be provided with the limiting column. Of course, the two may also be reversed, and the embodiment of the present application will not be described here.

[0057] Furthermore, in an embodiment of the present application, the set angle can be half of the angle between the center lines of the two adjacent inner ring air inlet channels 301. In the initial state (i.e., the technical solution in the research and development process), the center lines of the inner ring air inlet channel 301 and the corresponding outer ring air inlet channel 201 are collinear. After controlling the inner ring cavity 300 to rotate on the main body 100 to a set angle, the center line of the inner ring air inlet channel 301 is the symmetry line of the center lines of the two adjacent outer ring air inlet channels 201, even if the guide 302 and the outer ring air inlet channel 201 are arranged relative to each other.

[0058] Combine Figure 7 as well as Figure 9 The bottom (bottom plate 303) of the inner ring cavity 300 of the embodiment of the present application is provided with a plurality of first connecting holes 308, and the main body 100 (at the stop 102) is provided with a plurality of second connecting holes 104 and a plurality of third connecting holes 105. The second connecting holes 104 and the third connecting holes 105 are arranged alternately, and the first connecting holes 308 can be selectively matched with the second connecting holes 104 or the third connecting holes 105 to fix the inner ring cavity 300 on the main body 100.

[0059] In the product under development, the first connecting hole 308 is matched with the second connecting hole 104 by screws to fix the inner ring cavity 300 on the main body 100; when modifying the product under development, it is only necessary to add a slide groove at the bottom of the inner ring cavity 300 (bottom plate 303), and add a limit column and multiple third connecting holes 105 on the top of the main body 100, and control the inner ring cavity 300 to rotate on the main body 100 to a set angle, and then use screws to match the first connecting hole 308 with the third connecting hole 105 to fix the inner ring cavity 300 on the main body 100 again, which is convenient and quick.

[0060] In addition, by controlling the rotation of the inner ring cavity 300 on the main body 100 , the secondary air replenishment amount of the inner ring cavity 300 and the outer ring cavity 200 can also be adjusted to adapt to different application scenarios.

[0061] On the other hand, the present application also provides a burner, which includes the above-mentioned gas distribution plate.

[0062] The burner and gas stove with the above-mentioned gas distribution plate can reduce the amount of secondary air added to the inner ring cavity 300 and increase the amount of secondary air added to the outer ring cavity 200 to improve the combustion condition of the burner, and has great practical value.

[0063] Combine Figure 5 as well as Figure 6 The burner of the embodiment of the present application further includes an outer ring fire cover 400 and an inner ring fire cover 500. The outer ring fire cover 400 is supported by the outer ring cavity 200, and the inner ring fire cover 500 is supported by the inner ring cavity 300. Secondary air can be introduced into the inner side of the outer ring cavity 200 through the outer ring air inlet channel 201 to supply secondary air to the inner side of the outer ring fire cover 400 and the inner and outer sides of the inner ring fire cover 500. The secondary air inside the outer ring cavity 200 can be introduced into the inner side of the outer ring cavity 200 through the inner ring air inlet channel 201. The channel 301 is introduced into the inner side of the inner ring cavity 300 to supply secondary air to the inner side of the inner ring fire cover 500. In addition, the secondary air introduced through the outer ring air inlet channel 201 needs to flow laterally under the guidance of the guide 302 to enter the inner ring cavity 300 through the inner ring air inlet channel 301, thereby reducing the amount of secondary air supplemented to the inner ring cavity 300 and increasing the amount of secondary air supplemented in the outer ring cavity 200 to improve the combustion condition of the burner.
