Description

Technical Field

[0001] The present invention relates to a gas burner, and more particularly to an ignition device integrated gas burner which is easy to carry and does not require an additional ignition device. Background Art

[0002] A gas burner, especially a portable gas burner, is a tool for cooking with gas, and has a burner head and a flow path for delivering gas to the burner head through a gas inlet and a gas outlet. In addition, a gas regulating knob can adjust the amount of gas discharged to the burner head. In addition, for the convenience of use, the burner head has an automatic ignition device that generates sparks, and the automatic ignition device is activated using the gas regulating knob.

[0003] Korean Patent No. 10-0674409 (hereinafter referred to as Public Invention 1) discloses a type of such a gas burner. As mentioned above, Public Invention 1 discloses a method of igniting by pressing the knob in the axial direction while turning the knob. This method does not cause much inconvenience in burners with large weight and volume, but in small burners used outdoors such as camping, it is difficult to hold with both hands and has the disadvantage of being very inconvenient to operate. In addition, for small burners that do not have a separate regulator and require fine adjustment of the gas discharge amount, it is difficult to achieve this through the structure of Public Invention 1, and a new structure needs to be developed.

[0010] In order to solve the above technical problems, an embodiment of the present invention provides a gas burner, characterized in that it includes: a valve body, which forms a gas inlet and a gas outlet connected to a burner head, forming a gas flow path connecting the gas inlet and the gas outlet; a main shaft, including a main shaft head that is inserted into the valve body in a rotatable and linearly movable manner to adjust the opening and closing amount of the gas flow path; an ignition device, which generates sparks in the burner head according to the pressing action of the ignition device head, wherein the main shaft is rotatably and linearly movable to the valve body between a locking position where the main shaft head closes the gas flow path, an opening position where the gas flow path is opened, and an ignition position where the main shaft is rotated from the opening position to a further opening direction, and further includes: an ignition device pressing portion, which rotates in conjunction with the rotation operation between the ignition positions at the opening position of the main shaft, and generates sparks by pressing the ignition device head.

[0011] Preferably, the rotation range of the main shaft between the locking position and the opening position is greater than 200 degrees and less than 500 degrees.

[0012] Effectively, the spindle is further rotatable in the ignition position.

[0018] (Effects of the Invention)

[0019] According to the means for solving the problems of the present invention described above, various effects including the following can be achieved. However, the present invention does not necessarily require the following effects to be achieved simultaneously.

[0020] First, even if the main shaft rotates and moves linearly, it can automatically ignite, not only can the gas volume be finely adjusted, but it also has the convenience of automatic ignition with one hand. In particular, the discharge volume can be finely adjusted without a separate regulator.

[0021] Furthermore, the main shaft is arranged to be further rotatable in the ignition direction at the ignition position, so that a tolerance margin can be ensured during manufacturing.

[0022] In addition, even if there is an error in the exact locking position of the main shaft due to manufacturing tolerance, the locking state can be maintained by additional rotation in the movable slot, so there is an advantage that there is no need to improve manufacturing precision.

[0047] Specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0048] Figure 1 is a perspective view showing a main part of a gas burner according to an embodiment of the present invention, Figure 2 is based on Figure 1 The cross-sectional view of the cutting line II-II, Figure 3 yes Figure 2 A cross-sectional view of a valve body.

[0049] As shown in these drawings, a gas burner according to an embodiment of the present invention includes: a valve body 100, which forms a gas outlet 112 connected to a gas inlet 111 and a burner head 10, and forms a gas flow path 113 connecting the gas inlet 111 and the gas outlet 112; a spindle assembly 200, which includes a spindle head 211 that is inserted into the valve body 100 so as to be rotatable and linearly movable to adjust the opening and closing amount of the gas flow path 113; and an ignition device 40, which generates sparks in the burner head 10 according to the pressing action of the ignition device head 41.

[0050] The gas burner includes: a base plate 30, which supports the floor; a valve body 100, which is fixed to the upper side of the base plate 30; a burner head 10, which is combined with the upper side of the valve body 100 to spray flames; a gas coupling area 20, which is formed on one side of the valve body 100 and is combined with the gas barrel; a main shaft 210, which is combined with the valve body 100 on the opposite side of the gas coupling area 20; and an ignition device 40, which is combined with the lower side of the main shaft 210.

[0051] The gas inlet 111 of the valve body 100 is communicated with the gas coupling area 20 , and the gas outlet 112 is communicated with the burner head 10 .

[0052] like Figure 3 As shown, the valve body 100 includes the aforementioned gas inlet 111, the gas outlet 112, and the gas flow path 113 connecting the gas inlet 111 and the gas outlet 112, and a main shaft placement portion 120 is formed at a position connected to the gas flow path 113. The main shaft placement portion 120 includes: an inlet communication portion 121 connected to the gas inlet 111; an outlet communication portion 122 connected to the gas outlet 112; and a screw connection portion 123 connected to the screw forming portion 215 of the main shaft. The diameters of the inlet communication portion 121, the outlet communication portion 122, and the screw connection portion 123 increase in steps. As a result, an opening and closing amount adjustment jaw 124 is formed between the inlet communication portion 121 and the outlet communication portion 122, and a screw support jaw 125 is formed between the outlet communication portion 122 and the screw connection portion 123.

[0053] The spindle assembly 200 includes a spindle 210 , a spindle fixing member 230 , an ignition device pressing member 240 , a contact pressure spring 250 , an end cover 260 , a spindle handle 270 , and a rotation force transmission member 280 .

[0054] Figure 4 yes Figure 2 A cross-sectional view of the main shaft, Figure 5 yes Figure 4 A perspective view of the main axis, Figure 6 and Figure 7 This is a partial enlarged cross-sectional view of the spindle head and the jaw opening and closing adjustment area based on the spindle position.

[0055] As shown in these figures, the main shaft 210 includes: a main shaft head 211, which opens and closes the gas flow path 113; an outlet opening and closing portion 213, which opens and closes the gas flow outlet 112 formed in the main shaft head 211; a first sealing placement portion 214 and a second sealing placement portion 215, which are formed with a reduced diameter compared to the outlet opening and closing portion 213; a screw forming portion 216, which is formed with an outer diameter larger than the outlet opening and closing portion 213, and a thread is formed on the outer peripheral surface; a transfer member placement portion 217, which is used to place the rotational force transfer member 280, and is formed in a plate shape; a handle fixing hole 218, which is formed to pass through the end of the transfer member placement portion 217; the rotational force transfer member 280, which is inserted into the transfer member placement portion 217 and can be movably arranged in the length direction of the main shaft 210; a contact pressure spring 250, which contacts and presses the rotational force transfer member 280 in the direction of the ignition device pressing member 240.

[0056] The main shaft 210 is cylindrical and rotatably formed on the main shaft seating portion 120 .

[0057] The spindle head 211 is slightly tapered with a gradually increasing diameter toward the handle fixing hole 218, so that the amount of opening and closing the gas flow path 113 gradually increases or decreases according to the longitudinal position. Figure 6 and Figure 7 As shown, the flow rate of the fuel gas is finely adjusted by gradually changing the gap between the spindle head 211 and the opening and closing amount adjusting jaw 124 .

[0058] The first seal 292 and the second seal 293 are respectively mounted on the first seal mounting portion 214 and the second seal mounting portion 215. The first and second seals 292-293 are formed of an elastic material.

[0059] The screw forming portion 216 is coupled to the screw coupling portion 123 to guide the longitudinal movement of the main shaft 210 based on the rotation of the main shaft 210. One longitudinal surface of the screw forming portion 216 is supported by the screw supporting jaw 125.

[0060] Figure 8 yes Figure 2 A perspective view of the spindle fixing member.

[0061] In the center of the main shaft fixing component 230, a fixing component insertion hole 231 for inserting the main shaft 210 is formed through-through, and includes: a fixing component insertion portion 232, which is inserted into the screw connection portion 123; a pressing component placement portion 234, which has a larger diameter than the fixing component insertion portion 232 and can be inserted into the ignition device pressing component 240; and a fixing component head 235, which has a larger diameter than the pressing component placement portion 234.

[0062] One end 236 in the longitudinal direction of the main shaft fixing member 230 supports the other end of the screw forming portion 216 so as to face the gas flow path 113 .

[0063] Fig. 9 yes Figure 2 A perspective view of a rotational force transmitting component.

[0064] The rotation force transmission member 280 is in the shape of a disk, and the center thereof is penetrated to form a transmission member engaging hole 282 in the shape of a long hole so as to be inserted into the transmission member placement portion 217. On one side of the outer periphery, a main shaft ignition engaging portion 281 is formed to protrude in the thickness direction. The main shaft ignition engaging portion 281 is inserted into the movable slot 242 described later and is connected to the ignition engaging jaw 243. The main shaft ignition engaging portion 281 is in the open position ( Fig.13 , Fig.14 ) and connected with the ignition card connecting jaw 243.

[0065] Fig.10 yes Figure 2 A perspective view of an ignition device pressing member.

[0066] One end of the ignition device pressing member 240 forms the ignition device pressing portion 241, which is rotatably disposed on the main shaft 210 to form an ignition engaging jaw 243. In addition, the ignition device pressing portion 241 is farther from the rotation center of the main shaft 210 than the ignition engaging jaw 243.

[0067] The ignition device pressing member 240 is formed in a plate shape, the ignition device pressing portion 241 is formed protrudingly on the outer side of the ignition device pressing member 240, and a movable slot 242 is formed in a circular arc shape to allow the main shaft ignition clamping portion 281 to be inserted and moved, and the ignition clamping jaw 243 is formed at one end of the movable slot 242. In addition, a pressing member middle hole 245 is formed through the center of the ignition device pressing member 240, into which the pressing member placement portion 234 can be inserted. That is, in the open position ( Fig.13 , Fig.14 ), the ignition device pressing portion 241 and the ignition position ( Fig.15 ) are rotated in linkage, and by pressing the ignition device head 41, the ignition device 40 generates sparks.

[0068] The movable slot 242 is in the locking position ( Fig.11 , Fig.12 ) is formed longer to prevent the spindle ignition clamping portion 281 from being interfered by the end of the movable slot 242.

[0069] A spindle handle 270 formed of a wire is assembled at the end of the handle fixing hole 218 of the spindle 210, and an end cap 260 is inserted into the front end of the spindle handle 270 and one end is supported by the spindle handle 270. In addition, a contact pressure spring 250 is provided, one end of which is supported by the end cap 260 and the other end of which is supported by the rotational force transmission member 280. Therefore, the contact pressure spring 250 presses the rotational force transmission member 280 toward the ignition device pressing member 240, and the connection relationship between the ignition device pressing member 240 and the rotational force transmission member 280 is reliably maintained regardless of the position of the spindle 210.

[0070] The ignition device 40 is a device that uses a piezoelectric element to generate electric sparks, and includes: an ignition device body 42; an ignition device head 41, which is movably arranged on the ignition device body 42 in the length direction; and a spark generating part 43, which is arranged on the burner head 10. As the ignition device head 41 is pressed, the generated electricity is used to generate sparks.

[0071] Preferably, the ignition device 40 is located at the lower side of the valve body 100, and the ignition device head 41 is inclined upward. In this way, the range of the ignition device pressing part 241 that can rotate without interference can be further increased, and the ignition device 40 can be stably fixed to the ground frame.

[0072] Below Figures 11 to 15 As a reference, the relationship between the main shaft, the rotational force transmission member, the ignition device pressing member, and the ignition device will be described.

[0073] Fig.11 In the locked position Figure 2 A cross-sectional view of Fig.12 is in the locked position, from Figure 2 The front view of the rotational force transmission member and the ignition device pressing member and the ignition device as seen on the right side, Fig.13 In the open position Figure 2 A cross-sectional view of Fig.14 is in the open position, from Figure 2 The front view of the rotational force transmission member and the ignition device pressing member and the ignition device as seen on the right side, Fig.15 is in the ignition position, from Figure 2 A front view of the rotational force transmission component and the ignition device pressing component, and the ignition device as seen on the right side.

[0074] The spindle 210 is in a locked position ( Fig.11 , Fig.12 ), open the open position of the gas flow path 113 ( Fig.13 , Fig.14 ), the ignition position ( Fig.15) are arranged in the valve body 100 to rotate and move linearly between.

[0075] The locking position of the spindle 210 ( Fig.11 , Fig.12 ) and the open position ( Fig.13 , Fig.14 ) has a rotation range of more than 180 degrees and a maximum of 500 degrees. Therefore, the forward and backward movement of the main shaft 210 can be finely adjusted to finely increase or decrease the amount of gas flowing in the gas flow path 113.

[0076] The large rotation range of the main shaft 210 as described above is achieved by the dual structure of the ignition device pressing member 240 forming the moving slot 242 and the rotation force transmission member 280 rotating together with the main shaft 210 .

[0077] That is, if the ignition device pressing portion 241 is directly fixed to the main shaft 210 , it is difficult to ensure a large rotation amount of 180 degrees or more due to interference with the ignition device 40 .

[0078] Reference Figures 11 to 15 Provide detailed explanation.

[0079] by Fig.11 As a reference, the spindle 210 moves to the left as far as possible and is located in the locking position, such as Fig.12 As shown, the main shaft ignition clamping portion 281 is located in the middle portion of the moving slot 242 .

[0080] Afterwards, if Fig.14 , rotate the main shaft 210 in the counterclockwise direction so that the main shaft ignition clamping portion 281 is connected with the ignition clamping jaw 243, and the main shaft 210 is as follows Fig.13 , moves to the right to open the gas flow path 113.

[0081] Secondly, if Fig.15 When the main shaft 210 is further rotated counterclockwise, the main shaft ignition clamping portion 281 applies pressure to the ignition clamping jaw 243 in the counterclockwise direction, and the ignition device pressing portion 241 applies pressure to the ignition device head 41. As the ignition device head 41 is pressed, the ignition device 40 starts to generate sparks, thereby achieving ignition.

[0082] As described above, the gas burner according to one embodiment of the present invention can automatically ignite even if the main shaft 210 rotates and moves linearly, and can not only finely adjust the gas volume, but also has the convenience of automatic ignition with one hand. In particular, the discharge volume can be finely adjusted without an additional regulator.

[0083] like Fig.12In the locked position, the spindle ignition clamping portion 281 is located in the middle of the movable slot 242. Even if there is an error in the exact locking position of the spindle due to manufacturing tolerances, additional rotation can be made in the movable slot 242 to maintain the locked state. Therefore, there is an advantage that there is no need to improve manufacturing precision.

[0084] Furthermore, in order to finely adjust the gas flow rate of the main shaft 210, the rotation amount of the main shaft 210 at the locking position and the ignition position can be greatly increased. Fig.16 After the main shaft ignition clamping part 281 further rotates in the clockwise direction, it further rotates together with the ignition device pressing member 240 while being in contact with the clamping jaw on the opposite side of the moving slot 242, i.e., the open clamping jaw 244. In this case, the rotation range of the main shaft 210 is the sum of the rotation range allowed by the moving slot 242 and the rotation range of the ignition device pressing member 240 within the limit where the ignition device pressing part 241 is not interfered. Therefore, a rotation amount of more than 200 degrees can be ensured.

[0085] Furthermore, the main shaft 210 is configured to be able to be in the ignition position ( Fig.14 ) further to the ignition direction (with Figure 1 The rotation direction is counterclockwise based on the reference, thereby ensuring the tolerance margin during manufacturing.

[0086] The preferred embodiments of the present invention have been described above by way of example. However, the scope of the present invention is not limited to such specific embodiments, and appropriate changes can be made within the scope of the claims.
