Detailed Description

In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. The present utility model may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the utility model, whereby the utility model is not limited to the specific embodiments disclosed below.

In some embodiments, please refer to fig. 1 to 3, the present application provides a furnace front plate structure 100, wherein the furnace front plate structure 100 includes: a front plate 10 and a guard 20. The front plate 10 has a mounting hole 11 for mounting the ignition needle 200. The protection member 20 is protruded from a plate surface 1a of the front plate 10 and is disposed around a portion of the periphery of the mounting hole 11, for protecting the ignition needle 200.

In the furnace front plate structure 100, the shielding member 20 is mounted on the plate surface 1a of the front plate 10, and the shielding member 20 is disposed around a portion of the periphery of the mounting hole 11, so that the shielding member 20 forms a shielding structure around the periphery of the mounting hole 11. Thus, when the ignition needle 200 is installed in the installation hole 11, the protection piece 20 can provide protection for the ignition needle 200, so that the probability of being wetted is reduced, the ignition success of the igniter is ensured, and the service performance of the product is improved.

The front plate 10 is a plate-like structure on the front end side of the furnace body (which may be understood as the side facing the user), and the ignition needle 200 and the gas pipe 300 may be fixedly mounted on the front plate 10 so as to extend into the furnace body.

The guard 20 is protruding on a plate surface 1a of the front plate 10, and it should be understood that when the guard 20 is mounted on the plate surface 1a of the front plate 10, at least part of the guard is higher than the plate surface 1a of the front plate 10, so that a height difference is formed between the guard and the position where the mounting hole 11 is located, thereby providing a protection effect for the mounting hole 11. There are various connection manners between the guard 20 and the front plate 10, for example: the connection mode between the two can be, but is not limited to, bolting, clamping, welding, bonding, pinning, riveting and the like. In addition, when the front plate 10 is mounted on the furnace body, the ignition end of the ignition needle 200 extends into the furnace body, so that the protection member 20 should be disposed on a plate surface 1a of the front plate 10 facing the inside of the furnace body for effective protection of the ignition needle 200.

It will be appreciated that the guard 20 is disposed around a portion of the periphery of the mounting hole 11, and that the guard 20 is configured to extend around the periphery of the mounting hole 11, so as to shield the portion of the periphery of the mounting hole 11. In order to achieve protection of the ignition needle 200, care should be taken in installation that when the furnace front plate structure 100 is applied in a gas combustion apparatus, the front plate 10 should be installed at a proper angle so that the protection member 20 is located above the installation hole 11.

Further, referring to fig. 2 and 4, the guard 20 includes a main guard 21 and a side guard 22 connected to the main guard 21. The main guard plate 21 and the side guard plate 22 are both arranged on the same plate surface 1a of the front plate 10, and the main guard plate 21 and the side guard plate 22 are connected at an included angle and are arranged around the periphery of the mounting hole 11. Thus, the protection piece 20 is designed into the main protection plate 21 and the side protection plates 22, so that effective protection can be conveniently realized on different directions of the mounting hole 11, and the protection performance of the ignition needle 200 is improved.

The main guard 21 and the side guard 22 may be respectively configured as flat plates. When the main guard plate 21 and the side guard plates 22 are designed to be flat plates, an included angle θ can be formed between the two, for example: the included angle θ between the two may be, but is not limited to, 80 ° to 90 °. In particular, in some embodiments, the angle θ between the main shield 21 and the side shields 22 may be 90 degrees

Alternatively, the main guard 21 and the side guard 22 may be connected in a combined manner, for example: the connection manner between the main guard plate 21 and the side guard plate 22 can be, but is not limited to, welding, bonding, bolting, clamping, etc.; or can be integrally connected, such as: the connection mode of the two can be, but not limited to, injection molding, die casting, 3D printing, sheet metal bending, stamping and the like.

Further, referring to fig. 4 and 6, the main guard plate 21 is laterally disposed around the upper side of the mounting hole 11, and the side guard plate 22 is vertically disposed around one side of the mounting hole 11. Therefore, the main guard plate 21 and the side guard plates 22 are respectively and transversely and vertically enclosed on the corresponding sides of the mounting holes 11, so that the mounting holes 11 are protected in different directions, and the protection piece 20 achieves better protection effect on the mounting holes 11.

In the present embodiment, "lateral" and "vertical" refer to the extending directions of the main shield 21 and the side shield 22 on the front plate 10, respectively. For ease of understanding, taking fig. 1 as an example, the lateral direction may be the direction from "left" to "right" in fig. 1; or from "right" to "left". The vertical direction may be the direction from "up" to "down" in fig. 1; alternatively, the direction from "down" to "up".

Of course, when the front plate 10 has a rectangular or approximately rectangular structure, the lateral direction may be the longitudinal direction of the front plate 10, and the vertical direction may be the width direction of the front plate 10. When the front plate 10 is mounted on the furnace body, the main shield 21 is positioned above the mounting hole 11.

In some embodiments, referring to fig. 1 and 5, the main guard 21 is disposed obliquely with respect to a direction perpendicular to the plate surface 1a of the front plate 10, and an end of the main guard 21 away from the front plate 10 is offset toward the mounting hole 11. It is understood that the main shield 21 may be above the mounting hole 11 when the front plate 10 is placed upright, and the main shield 21 is inclined in a direction away from the front plate 10. Meanwhile, the portion of the main shield 21 farther from the front plate 10 is located lower. By such design, the periphery of the mounting hole 11 is effectively protected, meanwhile, liquid dripping on the main guard plate 21 is favorably drained along the direction away from the front plate 10, and the liquid is prevented from being collected at one end of the guard piece 20 close to the front plate 10, so that the risk of the ignition needle 200 being wetted is further reduced.

Note that, the main guard 21 is disposed obliquely on the front plate 10, which means that the main guard 21 is disposed at an angle to the front plate 10, for example: referring to fig. 5, in order to represent the angle between the front plate 1010 and the main guard plate 21, a dashed box is additionally added in fig. 5 to represent the front plate 1010 structure. The angle β between the main guard plate 21 and the front plate 10 may be, but is not limited to, 60 ° to 80 °. In particular, in some embodiments, the angle β between the main guard 21 and the front plate 10 may be 72 °.

In some embodiments, referring to fig. 4, the guard 20 further includes flanges 23, where the flanges 23 are located on the same side of the main guard 21 as the side guards 22, and are connected to opposite ends of the main guard 21. The flange 23 is provided to surround the outer periphery of the mounting hole 11. In this way, the flanges 23 and the side guard plates 22 are respectively arranged at the opposite ends of the main guard plate 21, so that the opposite sides of the mounting hole 11 can be effectively protected, the liquid in all directions is effectively prevented from wetting the ignition needle 200, and the protection effect is improved.

It should be noted that the flange 23 and the side guard 22 are respectively connected to opposite ends of the main guard 21 to form a certain protection space. Meanwhile, the connection mode of the flange 23 on the main guard plate 21 can be combined connection or integrated connection. In particular, in some embodiments, the flange 23, the main guard 21 and the side guard 22 are integrally formed.

In some embodiments, referring to fig. 4, the main guard 21 and/or the side guard 22 are provided with a fixing portion 24, where the fixing portion 24 is detachably connected to the front plate 10. Thus, the guard 20 is stably mounted on the front plate 10 by the fixing portion 24.

The fixing portion 24 may be provided only on one of the main shield 21 and the side shield 22; or may be provided on both the main guard 21 and the side guard 22.

Meanwhile, the fixing portion 24 may be combined to be connected to the main guard plate 21 or the side guard plate 22; or may be integrally connected to the main guard 21 or the side guard 22. In particular, in some embodiments, one side edge of the main guard 21 and the side guard 22 is folded to form the fixing portion 24.

Further, referring to fig. 4 and 6, the fixing portion 24 is provided with a first fixing hole 24112, and the front plate 10 is provided with a second fixing hole 1812 corresponding to the first fixing hole 24112. As such, the fixing portion 24 is fixed to the front plate 10 by penetrating the first and second fixing holes 24112 and 1812, respectively, with fasteners such as bolts, pins, rivets, etc.

In some embodiments, referring to fig. 6 and 7, the hole wall of the mounting hole 11 near the guard 20 is provided with a flow blocking portion 111. The choke 111 protrudes beyond the panel surface 1a of the front panel 10 having the guard 20. If the amount of liquid is large, such as when exposed to heavy rainfall during outdoor use, a portion of the liquid may flow past the guard 20 toward the mounting hole 11. For this purpose, a choke 111 is provided protruding from the wall of the mounting hole 11. When the liquid flows to the choke 111, the liquid cannot continue to flow towards the inside of the mounting hole 11 under the action of the choke 111, so as to realize a second protection, and further improve the protection effect on the ignition needle 200.

Meanwhile, the flow blocking part 111 protruding out of the plate surface 1a also has a positioning function for the installation of the protection piece 20, so that the protection piece 20 can be quickly and accurately surrounded on the periphery of the installation hole 11. In addition, the choke 111 can also support the guard 20, so that the guard 20 can be more stably mounted on the front plate 10.

Further, referring to fig. 1 and 6, the choke 111 extends along the length of the guard 20 on the wall of the mounting hole 11, so that the choke effect is better, and the protection effect on the ignition needle 200 is further improved.

In some embodiments, referring to fig. 3 and 6, the front plate 10 further has fixing holes 12 for mounting the gas pipe 300. The fixing hole 12 is communicated with the mounting hole 11, and a drainage part 13 is downwards convexly arranged on a hole wall between the fixing hole 12 and the mounting hole 11. It is known that when the liquid flows onto the wall of the mounting hole 11, the liquid may flow along the wall of the hole throughout the circumferential wall of the mounting hole 11. This easily causes the liquid to drop somewhere on the wall of the hole, with the risk of the ignition needle 200 getting wet. For the sake of understanding that the drainage portion 13 is protruded downward, reference may be made to fig. 6, and the drainage portion 13 extends in a direction pointed downward in fig. 6.

For this reason, in the present embodiment, the drainage portion 13 is provided to protrude from the wall of the hole between the fixing hole 12 and the mounting hole 11, so that even if the liquid flows onto the wall of the mounting hole 11, the liquid flows along the wall of the hole to the drainage portion 13, and drops occur at the drainage portion 13. The liquid is collected by the convex drainage portion 13 and is dropped between the fixing hole 12 and the mounting hole 11, so that the position of the ignition needle 200 is avoided, and the protection effect on the ignition needle 200 is improved.

The liquid dropped from the drainage portion 13 can be discharged from between the fixing hole 12 and the mounting hole 11 into the furnace body. Wherein, the fixing hole 12 is used for installing the gas pipe 300, a part of the gas pipe 300 stretches into the furnace body, and a plurality of gas outlets 310 are formed on the part stretching into the furnace body. When ignition of the ignition needle 200 is successful, the fuel gas is discharged from the gas outlet 310 and ignited.

Meanwhile, the number of the mounting holes 11 and the fixing holes 12 may be one or plural. When the number of the mounting holes 11 and the fixing holes 12 is plural, the mounting holes 11 and the fixing holes 12 are distributed as a whole at intervals in the lateral direction of the front plate 10.

In addition, when the number of the mounting holes 11 is plural, the number of the guard 20 may be one or plural. When the number of the guard members 20 is one, all the mounting holes 11 are protected by the same guard member 20; when the number of the shielding members 20 is plural, the number relationship between the shielding members 20 and the mounting holes 11 may be one-to-one, one-to-many, or the like.

It should be noted that, the flow blocking portion 111 may directly fix a protruding structure on the hole wall between the fixing hole 12 and the mounting hole 11; a recess 121 may be formed in a hole wall of the fixing hole 12, such as cutting or grooving the hole wall, so that a convex structure is formed between the fixing hole 12 and the mounting hole 11.

Further, referring to fig. 1 and 7, a part of the structure of the guard 20 extends along the outer periphery of the mounting hole 11, and one end thereof is disposed towards the drainage portion 13. In this way, the liquid on the protecting piece 20 can be drained onto the drainage part 13, and then the liquid is concentrated by the drainage part 13 to drop between the fixing hole 12 and the mounting hole 11, so that the liquid is prevented from easily dropping into the mounting hole 11 due to the dispersion flow.

The part of the structure of the guard 20 is disposed toward the drainage portion 13, and may be a flange 23 on the guard 20. Such as: the guard 20 includes a main guard 21, and flanges 23 and side guards 22 provided at opposite ends of the main guard 21. One end of the flange 23 is provided toward the drainage portion 13.

In some embodiments, referring to fig. 3, to facilitate the installation of the front plate 10 on the furnace body, the front plate 10 is provided with a first flange 14 and a second flange 15 at opposite ends along the width direction (or vertical direction) thereof, respectively. Meanwhile, the guard 20 is located at a side of the mounting hole 11 facing the first flange 14. Of course, the mounting flanges 16 may be provided at opposite ends of the front plate 10 in the longitudinal direction (or transverse direction) thereof, respectively, to be more stably mounted on the furnace body.

In addition, to improve the structural strength of the front plate 10, the front plate 10 may be provided with reinforcing ribs 17, such as: one plate surface 1a of the front plate 10 is protruded toward the other plate surface 1a to form a reinforcing rib 17.

In some embodiments, a furnace body includes the furnace body front plate structure 100 of any of the above. The guard 20 is provided on a plate surface 1a of the front plate 10 facing the inside of the furnace body.

The furnace body adopts the furnace body front plate structure 100, the protecting piece 20 is installed on one plate surface 1a of the front plate 10, and the protecting piece 20 is arranged around part of the periphery of the installation hole 11, so that the protecting piece 20 forms a protecting structure on the periphery of the installation hole 11. Thus, when the ignition needle 200 is installed in the installation hole 11, the protection piece 20 can provide protection for the ignition needle 200, so that the probability of being wetted is reduced, the ignition success of the igniter is ensured, and the service performance of the product is improved.

In some embodiments, referring to fig. 3, a gas combustion apparatus includes the above furnace.

The above gas combustion device adopts the above furnace front plate structure 100, the guard 20 is mounted on a plate surface 1a of the front plate 10, and the guard 20 is disposed around a portion of the periphery of the mounting hole 11, so that the guard 20 forms a guard structure around the periphery of the mounting hole 11. Thus, when the ignition needle 200 is installed in the installation hole 11, the protection piece 20 can provide protection for the ignition needle 200, so that the probability of being wetted is reduced, the ignition success of the igniter is ensured, and the service performance of the product is improved.

It should be noted that the gas combustion apparatus may further include an ignition needle 200 and a gas pipe 300. The ignition needle 200 is inserted into the mounting hole 11 and extends into the furnace body. At the same time, the gas pipe 300 is also fixed to the front plate 10 and extends into the furnace.
