Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of gas stoves, in particular to a gas distribution plate and a gas stove. Background Art
[0002] The gas distribution plate is an important structure on the gas stove, which is used to divide the gas input from the burner into multiple streams and transport them in the direction of the fire cover. The gas distribution plate includes an inner ring and an outer ring, the inner ring is connected to the burner, and the outer ring is sleeved on the inner ring and is provided with a gas groove. Since the distance between the outer ring and the burner is relatively large, three straight channels are usually arranged on the gas distribution plate to transmit the gas input from the burner to the gas groove of the outer ring. However, in the existing gas distribution plate, the straight channels are arranged along the radial direction of the outer ring, which causes the gas in each straight channel to flow into the gas groove in a direction perpendicular to the wall of the gas groove. After being blocked by the side wall of the gas groove, the gas flowing out of the straight channel will be relatively evenly divided into two streams flowing in opposite directions. For the convenience of description, these two streams are referred to as clockwise branches and counterclockwise branches. This phenomenon will lead to the following problems: the clockwise branch of the gas flowing out of one straight channel will collide with the counterclockwise branch of the gas flowing out of another straight channel in the gas groove, resulting in uneven fire in the outer ring, which has an adverse effect on the cooking effect of the gas stove. Utility Model Content
[0003] Based on this, it is necessary to provide a gas distribution plate and a gas stove to address the above problems, which can prevent airflow collision in the outer ring, facilitate uniform fire in the outer ring, and improve the cooking effect of the gas stove.
[0004] In order to solve the above problems, the utility model provides the following technical solutions:
[0005] A gas distribution plate, comprising:
[0006] Inner ring;
[0007] A base, connected to the inner ring, provided with a first gas inlet for inputting gas;
[0008] An outer ring, sleeved on the inner ring, provided with an annular gas groove; and
[0009] A plurality of gas transfer parts are provided, each of which has a gas transfer channel therein, the gas transfer channel connects the first gas inlet with the gas tank, the plurality of gas transfer channels are arranged at intervals along the circumference of the base, and the center line of each gas transfer channel is curved, and the gas outlet of each gas transfer channel is in a clockwise direction or the gas outlet of each gas transfer channel is in a counterclockwise direction.
[0010] The gas distribution plate has at least the following beneficial effects:
[0011] Because the gas outlet of each gas transmission channel is in the clockwise direction or the gas outlet of each gas transmission channel is in the counterclockwise direction, the gas flowing out of each gas transmission channel will first flow to the side wall of the gas groove at an angle relative to the side wall of the gas groove, and then flow in the same direction of rotation along the gas groove, that is, the gas flowing out of each gas transmission channel will not be divided into two air flows flowing in opposite directions after being blocked by the side wall of the gas groove, which can prevent the air flow collision in the outer ring, is conducive to uniform fire of the outer ring, and is conducive to improving the cooking effect of the gas stove.
[0012] In one embodiment, the plurality of gas transmission elements are evenly distributed around the circumference of the inner ring.
[0013] Such an arrangement is conducive to uniform fire discharge of the outer ring.
[0014] In one embodiment, the center line of the gas transmission channel is in an arc shape.
[0015] Such arrangement facilitates manufacturing.
[0016] In one embodiment, the wall of the air transfer channel includes a first bottom wall, a top wall, a first side wall and a second side wall, a first guide rib is protruding from the first bottom wall, and the first guide rib is spaced apart from the top wall, the first side wall and the second side wall.
[0017] With such arrangement, according to the Coanda effect, the fluid (water flow or air flow) tends to deviate from the original flow direction and flow along the protruding surface of the object. Because the first bottom wall is provided with a first guide rib, the gas will flow along the first guide rib during the flow in the gas transfer channel, thereby preventing the gas from floating in the middle and upper area of the gas transfer channel, thereby preventing backflow in the gas transfer channel, and facilitating faster mixing of the gas and flowing into the gas tank.
[0018] In one embodiment, the interval between the boundary line between the bottom wall and the first side wall and the first guide rib is D1, and the interval between the boundary line between the bottom wall and the second side wall and the first guide rib is D2, and both D1 and D2 are fixed values.
[0019] Such an arrangement is conducive to the stable flow of gas in the gas transmission channel.
[0020] In one embodiment, D1 = D2.
[0021] Such an arrangement is conducive to the stable flow of gas in the gas transmission channel.
[0022] In one embodiment, the cross section of the first guide rib is semicircular.
[0023] Such arrangement facilitates manufacturing.
[0024] In one of the embodiments, the groove wall of the gas groove includes a second bottom wall, a third side wall and a fourth side wall, and a second guide rib is protruded from the second bottom wall, and the second guide rib is spaced apart from the third side wall and the fourth side wall.
[0025] With such arrangement, the gas will flow along the second guide ribs during its flow in the gas tank, thus preventing the gas from flowing back in the gas tank and facilitating rapid and uniform ignition of the outer ring.
[0026] In one of the embodiments, a connecting rib is protrudingly provided on the second bottom wall, and two ends of the connecting rib are respectively connected to an end of the first guiding rib and an end of the second guiding rib.
[0027] Such a configuration, on the one hand, is conducive to preventing backflow during the flow of air; on the other hand, the first guide rib, the connecting rib and the second guide rib jointly play a role in guiding the gas flow, which is conducive to ensuring stable gas flow.
[0028] The utility model also provides a gas stove, which comprises the gas distribution plate mentioned above.
[0029] Because the gas stove includes the above-mentioned gas distribution plate, the gas stove has the technical effect of the above-mentioned gas distribution plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.
[0056] See also Figures 1 to 4The utility model first provides a gas distribution plate 10, which includes an inner ring 1, a base 2, an outer ring 3 and a gas transmission member 4. The base 2 is connected to the inner ring 1, and the outer ring 3 is sleeved on the inner ring 1. There are multiple gas transmission members 4, and the two ends of each transmission member are respectively connected to the base 2 and the outer ring 3. A first air inlet 21 is provided on the base 2, and the first air inlet 21 is used for the gas delivered by the stove. A gas groove 31 is provided in the outer ring 3, and the gas groove 31 is annular and surrounds the inner ring 1. There are multiple gas transmission members 4, and a gas transmission channel 41 is opened in each gas transmission member 4, and the gas transmission channel 41 connects the first air inlet 21 with the gas groove 31. The multiple gas transmission members 4 are arranged at intervals along the circumference of the base 2, so that the multiple gas transmission channels 41 are arranged at intervals along the circumference of the base 2. The center line of each gas transmission channel 41 is curved, see Figure 1 , the air outlet of each air transmission channel 41 is in the counterclockwise direction. Of course, in other embodiments, the air outlet of each air transmission channel 41 may also be in the clockwise direction.
[0057] Because the gas outlet of each gas transmission channel 41 is in the clockwise direction or the gas outlet of each gas transmission channel 41 is in the counterclockwise direction, the gas flowing out of each gas transmission channel 41 will first flow to the side wall of the gas groove 31 (i.e., the fourth side wall 313) at an angle relative to the side wall of the gas groove 31, and then flow in the same direction of rotation along the gas groove 31. Figure 1 In the illustrated embodiment, the gas flowing out of each gas transmission channel 41 will first flow obliquely relative to the side wall of the gas groove 31 (i.e., the fourth side wall 313) to the side wall of the gas groove 31, and then flow counterclockwise along the gas groove 31. Since the gas flowing out of each gas transmission channel 41 flows in this way, the gas flowing out of the three gas transmission channels 41 will flow counterclockwise along the gas groove 31. In this way, the gas flowing out of each gas transmission channel 41 will not be divided into two air flows flowing in opposite directions after being blocked by the side wall of the gas groove 31, which can prevent the occurrence of air flow collision in the outer ring 3, which is conducive to uniform combustion of the outer ring 3 and improves the cooking effect of the gas stove.
[0058] Preferably, see Figure 1 A plurality of gas transmission components 4 are evenly distributed around the circumference of the inner ring 1 , which is conducive to uniform ignition of the outer ring 3 .
[0059] Optionally, the plurality of air transmitting elements 4 may not be evenly distributed around the circumference of the inner ring 1 . For example, the interval between two of the air transmitting elements 4 may be slightly smaller, and the interval between the other two of the air transmitting elements 4 may be slightly larger.
[0060] The number of the air transfer elements 4 can be 3 or more, preferably 3 or 4.
[0061] Preferably, see Figures 1 to 4For ease of manufacturing, the center line of the gas transmission channel 41 is in an arc shape. Exemplarily, the gas transmission channel 41 may be an arc-shaped channel, or may be a shape that gradually narrows or widens from the inner ring 1 to the outer ring 3 .
[0062] Optionally, the center line of the gas transmission channel 41 may also be a part of a quadratic curve or a part of a parabola.
[0063] In the prior art, when the gas flows in the gas transmission channel 41, it will float in the middle and upper area of the gas transmission channel 41, which makes it easy for the lower area of the gas transmission channel 41 to flow back. Figure 3 and Figure 4 The walls of the gas transmission channel 41 include a first bottom wall 411, a top wall 412, a first side wall 413 and a second side wall 414. A first guide rib 5 is protruding from the first bottom wall 411. The first guide rib 5 is spaced apart from the top wall 412, the first side wall 413 and the second side wall 414. According to the Coanda effect, the fluid (water flow or air flow) tends to deviate from the original flow direction and flow along the protruding surface of the object. Because the first guide rib 5 is protruding from the first bottom wall 411, the gas will flow along the first guide rib 5 during the flow in the gas transmission channel 41, so that the gas can be prevented from floating in the middle and upper area of the gas transmission channel 41, thereby preventing backflow in the gas transmission channel 41, which is conducive to faster mixing of the gas and flowing into the gas tank 31.
[0064] Preferably, the interval between the boundary line between the bottom wall and the first side wall 413 and the first guide rib 5 is D1, and the interval between the boundary line between the bottom wall and the second side wall 414 and the first guide rib 5 is D2. In order to make the gas flow stably in the gas transmission channel 41 and prevent turbulence, D1 and D2 are fixed values. In other words, the boundary line between the bottom wall and the first side wall 413 and the first guide rib 5 are arranged at equal intervals, and the boundary line between the bottom wall and the second side wall 414 and the first guide rib 5 are also arranged at equal intervals.
[0065] More preferably, D1=D2, in other words, the first guide rib 5 is located in the middle of the bottom wall. Figure 1 and Figure 3 shown.
[0066] Preferably, see Figure 1 and Figure 3 For ease of manufacturing, the cross section of the first guide rib 5 is semicircular.
[0067] See also Figure 1 and Figure 3The groove wall of the gas groove 31 includes a second bottom wall 311, a third side wall 312 and a fourth side wall 313. A second guide rib 6 is convexly arranged on the second side wall 414. The second guide rib 6 is spaced apart from the third side wall 312 and the fourth side wall 313. In this way, when the gas flows in the gas groove 31, it will flow along the second guide rib 6, which can prevent the gas from flowing back in the gas groove 31, and is conducive to the rapid and uniform ignition of the outer ring 3.
[0068] See also Figure 1 and Figure 3 A connecting rib 7 is also protruded on the second bottom wall 311, and the two ends of the connecting rib 7 are respectively connected to the end of the first guiding rib 5 and the end of the second guiding rib 6. On the one hand, this is conducive to preventing the backflow during the flow of the airflow; on the other hand, the first guiding rib 5, the connecting rib 7 and the second guiding rib 6 play a role in guiding the gas flow, which is conducive to ensuring the stable flow of the gas.
[0069] Preferably, for ease of manufacture and to ensure stable gas flow, refer to Figure 3 The cross-sections of the first guiding rib 5, the connecting rib 7 and the third guiding rib are semicircles with the same diameter.
[0070] See also Figure 5 In the use state, the inner ring 1 is covered with an inner ring fire cover 20, and the outer ring 3 is covered with an outer ring fire cover 30. The holes on the inner ring fire cover 20 and the outer ring fire cover 30 are fire outlets. The base 2 is also provided with a second air inlet 22, and the inner ring 1 is provided with a first air outlet 11 connected to the second air inlet 22. Figure 6 The furnace head 40 includes a first ejector tube 401 and a second ejector tube 402. The first air inlet 21 is connected to the first ejector tube 401, and the second air inlet 22 is connected to the second ejector tube 402. The base 2 is also provided with a plurality of second air outlets 23, which correspond to the air transmission channels 41 one by one, and each air transmission channel 41 is connected to the first air inlet 21 through the corresponding second air outlet 23.
[0071] See also Figure 3 and Figure 4 For ease of manufacture, the gas distributor 10 is formed by splicing an upper body 8 and a lower body 9. The upper body 8 and the lower body 9 can be fixed together by, but not limited to, riveting, clamping, screwing, and the like.
[0072] See also Figure 6 The utility model further provides a gas stove, which includes the above-mentioned gas distribution plate 10. Because the gas stove includes the above-mentioned gas distribution plate 10, the gas stove has the technical effects of the above-mentioned gas distribution plate 10. Since the relevant technical effects have been fully described in the foregoing text, they will not be repeated here.
[0073] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0074] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
