Description

Technology Field

[0001] The present invention relates to a device for manually controlling air supplied to a gas burner. Background Technology

[0002] Figure 1 is a diagram showing the configuration of a typical gas burner.

[0003] Referring to FIG. 1, the gas burner (10) includes a gas chamber (20) connected to a branch pipe branching from a gas manifold, and a burner part (40) having a nozzle is connected to the other side of the gas chamber (20) through a gas supply pipe (30), so that the gas burner (10) is configured to be driven by a device operated by an operator.

[0004] The gas burner (10) removes moisture from the air through a burner section (40) formed on one side of the interior of the gas chamber (20). For example, gas supplied through the gas supply pipe (30) is ignited through the burner section (40) inside the gas chamber (20), and in this process, air is introduced to the rear of the burner section (40) to facilitate smooth ignition. That is, it is important to introduce secondary air from the outside during ignition through the burner section (40) to induce complete combustion of the gas burner.

[0005] As such, the gas burner requires air for gas combustion, but in some cases, the amount of air intake may be insufficient compared to the amount of gas injected into the nozzle. In this case, the combustion efficiency of the gas is reduced, which not only lowers the heat output but also causes problems such as the generation of harmful gases due to incomplete gas combustion. Therefore, it is necessary to ensure that air is properly supplied to the burner unit (40).

[0006] Conventionally, the method of controlling the air in the burner section involved temporarily installing a differential pressure gauge in the gas chamber (20), visually checking the differential pressure (airflow), turning off the operation of the burner, and then having a person enter the chamber configured in Fig. 4 to control it directly. Therefore, since the airflow is controlled after temporarily stopping the operation of the gas burner, there was an overall inconvenience and cumbersome problem. Prior art literature

[0010] Another objective of the present invention is to provide an air manual control device that allows easy verification of the degree of opening and closing of a door.

[0011] The technical problems of the present invention are not limited to those mentioned above, and other unmentioned technical problems will be clearly understood by those skilled in the art from the description below. means of solving the problem

[0012] A manual air control device for a gas burner according to an embodiment of the present invention for solving the above technical problem is a device for controlling air for a gas burner provided in a gas chamber, comprising: one handle; a handle driving shaft connected to the handle; a first moving block and a second moving block coupled to the handle driving shaft at a distance from each other; a first horizontal frame connecting the first moving block and an upper door; and a second horizontal frame connecting the second moving block and a lower door, and is characterized by controlling an air passage channel formed between the upper door and the lower door by moving the upper door and the lower door according to the operation of the handle.

[0013] On both sides of the first and second moving blocks, fixed dampers are each mounted spaced apart from the handle drive shaft to restrict the movement of the first and second moving blocks, which move according to the handle operation.

[0014] The above fixed damper may include a first fixed damper and a second fixed damper, wherein the first fixed damper includes a 1-1 fixed bracket and a 1-2 fixed bracket mounted spaced apart on both sides of the first movable block, and the second fixed damper may include a 2-1 fixed bracket and a 2-2 fixed bracket mounted spaced apart on both sides of the second movable block.

[0015] The other end of the handle drive shaft is supported by a support unit provided on the inner surface of the gas chamber, and a rotatable bearing may be mounted on the support unit.

[0016] A guide groove of a certain length is formed in the upper door and the lower door, and the guide groove can guide the movement of the upper door and the lower door when a fixing pin provided in the fixing panel is inserted therein.

[0017] It may further include a display unit that indicates the status of the air passage channel between the upper door and the lower door according to the above handle operation.

[0018] Depending on the operation of the handle above, the first moving block and the second moving block move in a direction closer to or further apart from each other. Effects of the invention

[0019] According to the present invention, an operator checks the air flow rate while the gas burner is operating, and if adjustment of the air flow rate is necessary, the air flow rate can be adjusted from the outside with just a simple handle operation, thereby enabling complete combustion of the gas burner.

[0020] According to the present invention, the movement of the upper door and the lower door forming the air passage channel can be controlled solely by operating the handle.

[0021] According to the present invention, since the range of movement of the upper door and the lower door can be limited by a fixed damper mounted on the handle drive shaft, there is an effect of preventing the door from opening more than necessary. Brief explanation of the drawing

[0030] The present invention will be described in more detail below based on the embodiments illustrated in the drawings.

[0031] The present invention may be configured to additionally install an air manual control device assembly (101, FIG. 2) that allows the upper and lower doors to be manually opened and closed to regulate the air supply to an existing gas burner. Alternatively, the invention may be configured to provide a gas burner equipped with the air manual control device.

[0033] FIG. 2 is a perspective view showing a gas burner according to an embodiment of the present invention.

[0034] Referring to FIG. 2, the gas burner (100) according to the present invention includes a gas chamber (20) connected to a branch pipe branching from a gas manifold, and a burner unit (40) having a nozzle is connected to the other side of the gas chamber (20) through a gas supply pipe (30). The burner unit (40) is driven by a device operated by an operator. The burner unit (40) may be mounted inside the gas chamber (20). The gas burner (100) includes upper / lower doors (160, 170; FIG. 3) mounted to move up and down on one side of the gas chamber (20) so as to supply air to the burner unit (40) and control the air. The upper / lower doors (160, 170) can be moved up and down by an air manual device described later to adjust the height of the passage through which the air passes.

[0035] According to an embodiment of the present invention, the gas burner (100) includes an air manual control device assembly (101) for moving the upper and lower doors. The air manual control device assembly (101) allows an operator to easily set the air flow rate by adjusting the degree of opening and closing (i.e., the air passage channel, A) of the upper and lower doors (160, 170) while the gas burner (100) is operating. The air manual control device assembly (101) may include configurations for simultaneously moving the upper and lower doors (160, 170) vertically in the upward and downward directions, respectively, according to handle operation.

[0036] The air manual control device assembly (101) will be described with reference to FIG. 3. FIG. 3 is a drawing specifically illustrating the air manual control device assembly (101) provided in the gas chamber (100).

[0037] Referring to FIGS. 2 and 3, the air manual control device assembly (101) is equipped with an upper door (160) and a lower door (170) on a fixed panel of a gas chamber (100), and controls the air passage channel (A) of an opening formed in the fixed panel according to the movement of the upper door (160) and the lower door (170). The air flow rate is controlled according to the air passage channel of the opening.

[0038] The air manual control device assembly (101) may be configured to include a handle (110), a handle drive shaft (120), a first movable block (130-1) and a second movable block (130-2), a first fixed damper (140-1, 140-2) and a second fixed damper (150-1, 150-2), a first horizontal frame (150-3) and a second horizontal frame (150-4).

[0039] A handle (110) is mounted on the outside of the gas chamber (20) so that a worker can easily operate it, and according to an embodiment, one can be mounted on the upper surface or side of the gas chamber (20), and the upper door (160) and the lower door (170) can be moved up and down simultaneously by operating only the handle (110).

[0040] One end of the handle drive shaft (120) is connected to the handle (110), and the other end is supported by a support unit (111) provided on the inner surface of the gas chamber (20). A rotatable bearing is built into the support unit (111) so that the handle drive shaft (120) can be rotated according to the operation of the handle (110). Additionally, a first screw thread and a second screw thread may be formed on the handle drive side (120) so as to rotate in different directions relative to the center. When the handle drive shaft (120) rotates in a forward direction (first direction) or a reverse direction (second direction) depending on the direction of operation of the handle, the first moving block (130-1) and the second moving block (130-2) mounted on the handle drive shaft (120) can move in a direction that moves closer to each other or in a direction that moves further apart. This configuration is intended to move the upper door (160) and the lower door (170) simultaneously using only one handle.

[0041] The first moving block (130-1) and the second moving block (130-2) can be mounted on the handle drive shaft (120). Then, they move along the handle drive shaft (120) according to the operation of the handle (110). For example, when the handle (110) is rotated in the forward direction (first direction), the first moving block (130-1) and the second moving block (130-2) move closer to each other, and when rotated in the reverse direction (second direction), the first moving block (130-1) and the second moving block (130-2) move further apart from each other. Therefore, when the handle (110) is operated in the forward direction, the upper door (160) and the lower door (170) move closer together, narrowing the air passage channel, and conversely, when the handle (110) is operated in the reverse direction, the upper door (160) and the lower door (170) move further apart, widening the air passage channel.

[0042] The first fixed damper (140-1, 140-2) and the second fixed damper (150-1, 150-2) can be fixed in a state where they are fitted onto the handle drive shaft (120). The first fixed damper (140-1, 140-2) and the second fixed damper (150-1, 150-2) can serve to limit the range of movement of the first moving block (130-1) and the second moving block (130-2). Specifically, each of the first fixed damper (140-1, 140-2) and the second fixed damper (150-1, 150-2) may include a pair of fixed brackets, namely 1-1 fixed bracket (140-1) and 1-2 fixed bracket (140-2), and 2-1 fixed bracket (150-1) and 2-2 fixed bracket (150-2). The 1-1 fixed bracket (140-1) and 1-2 fixed bracket (140-2) are fitted and fixed to the handle drive shaft (120) at a certain distance apart, so that the first moving block (130-1) moves only within a predetermined range of movement. Likewise, the 2-1 fixed bracket (150-1) and the 2-2 fixed bracket (150-2) are fixedly fitted at a certain distance apart from the handle drive shaft (120), so that the second moving block (130-2) moves only within a predetermined range of movement. The range of movement is related to the range of movement of the upper door (160) and the lower door (170), thereby allowing the degree of opening and closing of the air passage channel to be controlled.

[0043] The first horizontal frame (150-3) connects the first movable block (130-1) and the upper door (160), and can move the upper door (160) up and down according to the movement of the first movable block (130-1).

[0044] The second horizontal frame (150-4) connects the second moving block (130-2) and the lower door (170), and can move the lower door (170) up and down according to the movement of the second moving block (130-2).

[0046] Figure 4 is a drawing illustrating the movement of the upper door and the lower door.

[0047] According to the present embodiment, the upper door (160) and the lower door (170) are mounted on a fixed panel and must be configured to be movable in the up and down direction according to the operation of the handle (110).

[0048] As shown in FIG. 4, guide grooves (180) are formed in the upper door (160) and the lower door (170). The guide grooves (180) are formed for a predetermined length in the vertical direction of the upper door (160) and the lower door (170), and two guide grooves are formed in each door for stable movement.

[0049] A fixing pin (190) formed on a fixed panel is inserted into the guide groove (180). The fixing pin (190) is fixed to the fixed panel, and the guide groove (180) of the upper / lower doors (160, 170) moves up and down along the fixing pin (190) according to the operation of the handle (110). If the guide groove is not formed in the upper door (160) and the lower door (170), the upper door (160) and the lower door (170) must be moved only by the movement of the first horizontal frame (150-3) and the second horizontal frame (150-4), so stable movement may not be possible.

[0051] Meanwhile, according to an embodiment of the present invention, a display unit (not shown) indicating the state of handle operation may be included. The display unit may be a means for guiding how much the air passage channel is in accordance with the handle operation. The display unit may be provided in various forms, such as numbers, scales, dials, indicators, etc. Through this, the operator can know the state of rotation of the handle through the medium displayed on the display unit, and thus it will be possible to determine the degree of opening or closing of the upper door (160) and the lower door (170). Through this, it is possible to easily set the air flow rate.

[0053] According to this configuration, the operator checks the combustion state of the gas burner (110) through the inspection port and determines whether to adjust the air flow rate. Then, if the air flow rate is reduced or increased based on the determination, the handle (110) is operated to move the upper door (160) and the lower door (170) simultaneously, and the air flow rate can be adjusted as the air passage channel is adjusted according to the movement of the upper door (160) and the lower door (170). Furthermore, this air flow rate adjustment can be performed while the gas burner (100) is in operation.

[0055] As explained above, the present invention allows the upper door and the lower door forming the air passage channel to be moved simultaneously in the up / down direction by means of handle operation, so that the operator can simply adjust the air flow rate while the gas burner is operating.

[0057] Although the present invention has been described with reference to illustrated embodiments as above, these are merely exemplary, and it will be obvious to those skilled in the art that various modifications, changes, and equivalent alternative embodiments are possible without departing from the gist and scope of the invention. Accordingly, the true technical scope of protection of the present invention should be determined by the technical spirit of the appended claims. Explanation of the symbols
