Description

Technology Field

[0001] The present invention relates to a gas range, and more specifically, to a gas range capable of bidirectional operation that allows for easy operation from multiple positions by enabling the adjustment of the amount of gas or the gas flame not only from the front but also from the rear. Background Technology

[0002] Generally, portable gas stoves are designed to be portable and equipped with a gas cylinder filled with butane fuel, enabling various types of cooking. With the recent increase in outdoor activities such as camping, they are being supplied and used in a wide variety of designs and functions.

[0003] Most portable gas stoves of this type are used by several people sitting around them, but in this case, the gas volume control knob is provided only on the front, so its use is limited to one person, and other people, especially those on the opposite side, cannot control the gas volume. Furthermore, even when urgent gas flame adjustment is required, operation is only allowed from the front, which not only causes inconvenience but also makes it difficult to take quick safety measures.

[0004] As a prior art for solving these problems, the "Double-sided control system for a portable gas stove" disclosed in Korean Registered Utility Model No. 20-0339294 has been disclosed. This relates to a system in which a device for controlling the amount of gas or performing a locking function of a portable gas stove is installed on both the front and rear sides, i.e., both sides, to enable simultaneous operation.

[0005] However, such conventional technology merely functionally indicates that the amount of gas can be controlled from the front and rear, but does not present a specific configuration for this purpose. Consequently, it not only presents difficulties in actual application but also fails to resolve existing issues such as inconvenience and the difficulty of taking prompt safety measures. The problem to be solved

[0006] In order to solve the problems of the aforementioned conventional technology, the present invention aims to enable easy operation from multiple locations by allowing the amount of gas or the gas flame to be controlled not only from the front but also from the rear, thereby resolving the inconvenience of existing gas ranges that could only be operated from a limited location, and also to satisfy both convenience of use and safety by enabling safety measures, such as extinguishing the gas flame, to be performed quickly from the rear. means of solving the problem

[0007] In order to solve the problem described above, according to one aspect of the present invention, a gas range capable of bidirectional operation is provided, comprising: a case; a burner provided on the upper surface of the case; a gas regulator installed inside the case and provided to regulate the amount of gas supplied to the burner; a detachable connection part for detachably connecting a gas container to the gas regulator; a first knob rotatably installed on one side of the case and connected to the gas regulator to regulate the amount of gas supplied from the gas container; a second knob rotatably installed on the other side of the first knob in the case; and a knob interlocking part that connects the first knob and the second knob to rotate together, thereby rotating the first knob by the rotational operation of the second knob to operate the gas regulator.

[0008] The first knob and the second knob are installed on one side and the other side of the case so as to be rotatable by the first rotation axis and the second rotation axis, respectively, and the first rotation axis and the second rotation axis may be arranged in a line.

[0009] The knob linkage unit may be formed in the shape of a bar that is arranged parallel to the gas container connected by the detachable connection unit, by connecting both ends to each of the first extension unit and the second extension unit, which are arranged to extend laterally from each of the first rotation axis and the second rotation axis.

[0010] The knob interlocking part may be positioned such that the rotational position of the first knob or the second knob is located above the gas container when gas is supplied from the gas container, and is positioned such that it is moved away from the upper side of the gas container when the supply of gas from the gas container is cut off.

[0011] The above knob interlocking part may be formed to have a curvature facing the outer surface of the gas container.

[0012] The above knob linkage unit can transmit the rotational force of either the first knob or the second knob to the other through gear coupling.

[0013] The knob linkage unit may include: a first rotating plate and a second rotating plate arranged to rotate together on each of the first rotating shaft and the second rotating shaft; a first gear unit and a second gear unit consisting of a plurality of teeth arranged on the edges of each of the first rotating plate and the second rotating plate; a first pinion and a second pinion geared to each of the first gear unit and the second gear unit; and a connecting shaft installed to be rotatable inside the case, with the first pinion and the second pinion each fixed at both ends.

[0014] The above connecting shaft can be installed by being rotatably received by a shaft coupling portion provided on the inner bottom surface of the case.

[0015] The above case may be provided with a receiving groove on the inner bottom surface to accommodate a first pinion and a second pinion, which are fixed to both ends of the connecting shaft, spaced apart from each other. Effects of the invention

[0016] According to the gas range capable of bidirectional operation according to the present invention, by enabling the adjustment of the amount of gas or the gas flame not only from the front but also from the rear, it can be easily operated from multiple positions. This not only resolves the inconvenience of conventional gas ranges that were only capable of operation from a limited position, but also enables safety measures such as extinguishing the gas flame from the rear to be performed quickly, thereby satisfying the convenience and safety of use.

Specific details for implementing the invention

[0018] Since the present invention may have various embodiments through various modifications, specific embodiments are to be illustrated in the drawings as examples. Furthermore, the present invention should be understood not to be limited to these specific embodiments, but to include all modifications, equivalents, and substitutions that fall within the technical scope of the present invention.

[0019] Hereinafter, embodiments according to the present invention will be described in detail with reference to the attached drawings. Identical or corresponding components are assigned the same reference number regardless of the drawing symbols, and redundant descriptions thereof will be omitted.

[0020] FIG. 1 is a perspective view illustrating a gas range capable of bidirectional operation according to a first embodiment of the present invention, FIG. 2 is a rear perspective view illustrating a gas range capable of bidirectional operation according to a first embodiment of the present invention, and FIG. 3 is a cross-sectional view illustrating a key part of a gas range capable of bidirectional operation according to a first embodiment of the present invention.

[0021] Referring to FIGS. 1 to 3, a gas range (100) capable of bidirectional operation according to one embodiment of the present invention may include a case (110), a burner (120), a gas regulator (130), a detachable connection part (140), a first knob and a second knob (150, 160), and a knob interlocking part (170).

[0022] The case (110) is provided with at least three supports (116) positioned around the perimeter of the burner (120) on the upper surface to support a cooking appliance for heating, and the top plate (111) can be mounted so as to be detachably mounted upward together with the supports (116) so as to allow the burner (120) to be fully exposed to the outside.

[0023] The case (110) may be provided with a mounting portion (112) on one side that provides a space for mounting a gas container (1) and can be opened and closed by a cover (113), and may be provided with a first hole and a second hole (114, 115) for rotatably connecting a first knob and a second knob (150, 160), respectively.

[0024] The burner (120) is a type of gas burner and is provided on the upper surface of the case (110). When fuel gas, such as butane gas, is supplied from the gas container (1), it generates combustion heat by ignition, thereby heating the lower part of the cooking appliance supported by the support (116).

[0025] A gas regulator (130) is installed inside the case (110) and is provided to regulate the amount of gas supplied to the burner (120). The gas regulator (130) regulates the amount of fuel gas supplied from the gas container (1) to the burner (120) by adjusting the opening of the gas supply path through rotational operation of the first knob or the second knob (150, 160), which will be described later.

[0026] The gas regulator (130) is connected to the outlet side of the gas container (1) by a detachable connection part (140) and supplies fuel gas to the burner (120) side through a gas supply tube (131), and if necessary, a safety valve, etc. may be installed for safe handling of the gas.

[0027] The detachable connection part (140) allows the gas container (1) to be detachably connected to the gas regulator (130). For example, as in the present embodiment, the gas container (1) may be connected by magnetic force using a magnet, or as another example, the gas container (1) may be configured to be attached to or detached from the gas regulator (130) by a link member operated by a push lever provided on the front of the case (110). In addition, various configurations may be provided so that the gas container (1) is detachably connected to the gas regulator (130) by various known methods.

[0028] The first knob (150) is rotatably installed on one side of the case (110) and connected to the gas regulator (130) so as to regulate the amount of gas supplied from the gas container (1). That is, the first knob (150) can be rotatably installed in the first hole (114) provided on the front of the case (110) by the first rotation axis (151), and can regulate the opening of the inner supply path by tightening or loosening the valve member of the gas regulator (130).

[0029] The first knob (150) can be configured to perform not only the operation of the gas regulator (130) but also the ignition of the fuel gas. To this end, an ignition switch (180) is installed inside the case (110) so as to be located within the rotation radius of the first knob (150). When the rotation is operated, a locking part (153) provided inside presses the ignition switch (180), thereby causing the fuel gas to ignite on the side of the burner (120) by the ignition spark generated from a spark plug (not shown) located on the side of the burner (120) by the operation of the ignition switch (180).

[0030] The first knob (150) can be connected to or fixed with a member having the first rotation axis (151) by means of a bolt fastening, fitting, locking structure, or pin connection, so that it can be stably assembled into the first hole (114) by means of the first rotation axis (151), and furthermore, for integration, a tooth connection or spline connection, etc. can be made to the member having the first rotation axis (151).

[0031] The second knob (160) is rotatably installed on the other side of the first knob (150) in the case (110). That is, the second knob (160) can be rotatably installed in a second hole (115) provided on the rear side of the case (110) by a second rotation axis (161).

[0032] The second knob (160) can be connected to or fixed with a member having a first rotation axis (161) by means of a bolt fastening, fitting, locking structure, or pin connection, so that it can be stably assembled into the second hole (115) by means of a second rotation axis (161), and furthermore, for integration, a tooth connection or spline connection, etc. can be made to the member having the second rotation axis (161).

[0033] The first knob and the second knob (150, 160) are installed on one side and the other side of the case (110) so as to be rotatable by the first rotation axis and the second rotation axis (151, 161), respectively, and the first rotation axis and the second rotation axis (151, 161) may be arranged in a line, thereby increasing the reliability of the interlocking.

[0034] The knob linkage unit (170) connects the first knob and the second knob (150, 160) to rotate together, thereby allowing the gas regulator (130) to be operated by rotating the first knob (150) through the rotational operation of the second knob (160), and conversely, the second knob (160) can be rotated by rotating the first knob (150). At this time, the rotational directions of the second knob (160) and the first knob (150) in proportion to the opening may be opposite to each other, and it is preferable to display such opening size and direction indications on the outer surface of the case (110) for the convenience and identification of the operator.

[0035] The knob interlocking part (170) can be formed in the shape of a bar that is arranged parallel to the gas container (1) connected by the detachable connection part (140) by connecting both ends to the first extension part and the second extension part (171, 172), which are arranged to extend laterally from the first rotation axis and the second rotation axis (151, 161), respectively. Accordingly, the knob interlocking part (170) can provide a compact installation structure.

[0036] The knob interlocking part (170) can be positioned so that the rotational position of the first knob or the second knob (150, 160) is located on the upper side of the gas container (1) when gas is supplied from the gas container (1) (see FIG. 2), thereby giving a warning not to perform separation of the gas container (1) without properly shutting off the gas using the first knob or the second knob (150, 160), and can be positioned so as to move away from the upper side of the gas container (1) when the supply of gas from the gas container (1) is shut off (see FIG. 1), thereby enabling separation of the gas container (1) when the gas is properly shut off, and thus helping to safely operate the first knob or the second knob (150, 160).

[0037] The knob interlocking part (170) can be formed to have a curvature to face the outer surface of the gas container (1), and thus to have a curvature that partially wraps the gas container (1) from the outside (see FIG. 2), thereby reducing the space required for installation.

[0038] Referring to FIG. 4, a gas range (200) capable of bidirectional operation according to another example (second embodiment), The knob linkage unit (270) can transmit the rotational force of either the first knob or the second knob (250, 260) to the other through gear coupling. To this end, the first knob and the second knob (250, 260) can be configured to rotate in conjunction with each other by using a gear assembly or gearbox, etc., which utilizes a plurality of bevel gears or spur gears.

[0039] The knob interlocking part (270) is, for example as in the present embodiment, a first rotating plate and a second rotating plate (271, 272) arranged to rotate together with each of the first rotating shaft and the second rotating shaft (251, 261) which are installed to pass through the first hole and the second hole (214, 215) provided on the front and rear of the case (210), respectively; a first gear part and a second gear part (273, 274) consisting of a plurality of teeth provided on the edges of each of the first rotating plate and the second rotating plate (271, 272); a first pinion and a second pinion (275, 276) gear-coupled to each of the first gear part and the second gear part (273, 274); and the first pinion and the second pinion (275, 276) can be fixed to each of both ends, respectively. It may include a connecting shaft (277) installed to be rotatable inside the case (210). Here, the first gear section and the second gear section (273, 274) may be configured to have a plurality of teeth formed over a portion of the edges of the first rotating plate and the second rotating plate (271, 272), taking into account the rotation angle range of the first knob and the second knob (250, 260). Accordingly, for example, when the second knob (260) is rotated, the second rotating plate (272) rotates together with the second rotating shaft (261), and the second gear part (274) rotates the first pinion (275) together with the second pinion (276), and the first rotating shaft (251), which is geared to the first pinion (275) by the first gear part (273), rotates together with the first knob (250), thereby allowing the amount of fuel gas supplied from the gas container (1) to the burner side to be adjusted by the operation of the gas regulator (230).

[0040] The connecting shaft (277) can be installed by being rotatably received by a shaft coupling part (278) provided on the inner bottom surface of the case (210) for stable transmission of rotational force and a compact configuration. Additionally, the case (210) is provided with a receiving groove (211) on the inner bottom surface to receive a first pinion and a second pinion (275, 276) that are fixed to both ends of the connecting shaft (277) spaced apart from each other, so that the lower side of the receiving groove (211) not only acts as a protrusion supported on the bottom surface but also smoothly secures a receiving space for the first pinion and the second pinion (275, 276).

[0041] According to the gas range capable of bidirectional operation according to the present invention, the amount of gas or the gas flame can be controlled not only from the front but also from the rear, thereby allowing for easy operation from multiple positions.

[0042] Accordingly, according to the present invention, not only is the inconvenience of conventional gas stoves, which were only capable of operation at a limited location, resolved, but safety measures such as extinguishing the gas flame can also be quickly performed from the rear, thereby increasing the convenience and safety of use.

[0043] Although the present invention has been described with reference to the attached drawings, various modifications may be made within the scope of the technical spirit of the invention. Accordingly, the scope of the present invention should not be limited to the above-described embodiments, but should be defined by the claims and equivalents thereof. Explanation of the symbols
