Description

Technology Field

[0001] The present invention relates to a far-infrared multi-grill device, and more specifically, to a far-infrared multi-grill device that cooks meat using indirect heat so that the meat does not burn, removes unnecessary toxic substances using far-infrared rays, and provides meat with tender texture, allows for adjusting the height of the grill plate to grill meat in an optimal state, and can inhale and expel the odor or smoke of the grilled meat. Background Technology

[0002] While boiling and frying are methods for cooking meats such as beef and pork, grilling seasoned meat is also widely used in restaurants and homes. Historically, the method used to grill meat has been the use of charcoal.

[0003] It is generally known that the delicious taste of meat grilled over charcoal is due to the far-infrared rays emitted from the charcoal. Far-infrared rays refer to the long-wavelength infrared region and contain more heat compared to other regions of infrared radiation. When grilling meat, various wavelengths of light are present in the fire, but heating is primarily handled by light in the infrared region. However, while light in the short-wavelength region of the infrared spectrum causes meat to burn significantly during the high-temperature cooking process, far-infrared rays, which have long wavelengths, have the advantage of cooking meat without burning it because they are rich in heat despite having a lower temperature.

[0004] In other words, because charcoal emits a large amount of far-infrared rays compared to ordinary fire, it primarily cooks rather than burns the meat, ensuring that the meat is cooked thoroughly both inside and out without burning. Additionally, since the meat is cooked by the radiant heat of the charcoal, the juices do not evaporate, which has the advantage of allowing you to experience the rich flavor of the meat.

[0005] However, since grilling meat over charcoal is a direct fire method, there is a problem where smoke is generated as the meat partially burns. Furthermore, the process of preparing the charcoal outdoors, placing it in the oven, transporting it to the table, and disposing of the finished meat is not only cumbersome but also poses a risk of accidents, such as burns or fires during transport.

[0006] Accordingly, the method of grilling meat directly using gas is also widely used. However, while grilling meat using gas is convenient, it has the problem of burning the meat. In addition, since the meat is cooked by convection heat rather than by radiant heat from far-infrared rays, there is a disadvantage that the meat juices evaporate, causing the meat to lose its rich flavor.

[0007] To solve these problems, a roaster has been proposed that allows meat on a grill plate to be cooked using far-infrared rays generated from a germanium-containing furnace by passing the flame generated from a gas burner through a furnace that emits far-infrared rays.

[0008] However, the aforementioned oven had the disadvantage of having a low heat transfer rate, requiring the gas heater to be ignited and heated for a considerable amount of time before grilling meat, and being weak in strength, making it prone to breaking upon impact.

[0009] Meanwhile, even when using a stove, there was a problem where the gas combusted from the gas burner was directly transferred to the grill plate on which the meat was placed, causing the plate to heat up rapidly and the meat to burn.

[0010] To address these problems, the "lever-type height-adjustable meat grill" of Patent Registration No. 10-2248193 and the "meat grill with adjustable grill plate height" of Patent Registration No. 10-2235956 have been disclosed; however, the aforementioned prior art technologies have aspects that need improvement, such as the inconvenience of adjusting the height of the grill plate and the inability to efficiently vent smoke or odors from the grilling meat.

The lower part of the first gear forms a first stepped surface and a first inclined surface that repeatedly rise and fall axially along the circumference, and corresponding to the first gear, the upper part of the second gear along the circumference A second stepped surface and a second inclined surface are formed that repeatedly rise and fall in an axial direction, and as the second gear, which is meshed with the third gear by the power of the motor, rotates in the circumferential direction, the first and second stepped surfaces engage simultaneously, causing the first gear to rotate and rotate the grill plate; wherein when the lifting gear engages with the first gear by the lifting cylinder, the first gear stops rotating in the circumferential direction, and as the second gear rotates in the circumferential direction, the first stepped surface engaged with the second stepped surface is pushed in the axial direction of the first gear to raise and lower the grill plate. Effects of the invention

[0025] The present invention proposes a far-infrared multi-grill device as follows, which can remove unnecessary toxic components using far-infrared rays and provide tender meat, allows the height of the grill plate to be adjusted in stages (#3 to #7) to grill meat in an optimal state, and can inhale and exhaust the odor or smoke of the grilling meat, and is simple to operate by conveniently configuring the heat source unit and extending the fuel usage time by improving the fuel unit.

[0028] In addition, FIG. 4 is a side view illustrating a part of a far-infrared multi-grill device according to one embodiment of the present invention, and FIG. 5 and FIG. 6 are side views illustrating the operating state of a far-infrared multi-grill device according to one embodiment of the present invention.

[0029] In addition, FIGS. 7 and 8 are drawings for explaining the heat source part of a far-infrared multi-grill device according to one embodiment of the present invention, and FIGS. 9 to 11 are drawings for explaining other configurations of a far-infrared multi-grill device according to one embodiment of the present invention.

[0031] Referring to the drawings above, a far-infrared multi-grill device (10) according to one embodiment of the present invention may include: a grill plate (100) having an outlet (110) formed in the center downward; a main base (200) on which the grill plate (100) is placed; a driving unit (300) embedded in the main base (200) for rotating or raising the grill plate (100); an upright unit (400) formed vertically on one side of the main base (200); and a heat source unit (500) protruding from the upper part of the upright unit (400) and formed horizontally toward the grill plate (100).

[0032] Additionally, the driving unit (300) may include a first gear (310) surrounding the discharge port (110), a second gear (320) formed axially with the first gear (310), a third gear (330) meshing with the second gear (320) as a bevel gear, a motor (340) providing rotational power to the third gear (330), an elevator gear (350) meshing with the circumference of the first gear (310), and an elevator cylinder (360) for moving the elevator gear (350) back and forth.

[0033] Additionally, the lower part of the first gear (310) may form a first stepped surface (311) and a first inclined surface (312) that repeatedly rise and fall in an axial direction along the circumferential direction, and corresponding to the first gear (310), the upper part of the second gear (320) may form a second stepped surface (321) and a second inclined surface (322) that repeatedly rise and fall in an axial direction along the circumferential direction.

[0034] In addition, as the second gear (320), which is meshed with the third gear (330) by the power of the motor (340), rotates in the circumferential direction, the first and second stepped surfaces (321) engage simultaneously, causing the first gear (310) to rotate and the grill plate (100) to rotate.

[0035] Additionally, when the lifting gear (350) is engaged with the first gear (310) by the lifting cylinder (360), the second gear (320) rotates in the circumferential direction, thereby pushing the first step surface (311) engaged with the second step surface (321) in the axial direction of the first gear (310) to raise the grill plate (100).

[0036] That is, when the second gear (320), which is meshed with the third gear (330) by the power of the motor (340), rotates in the circumferential direction, the first gear (310) rotates by means of the first step surface (311) which is meshed with the second step surface (321), and the grill plate (100) can be rotated.

[0037] Additionally, when the lifting gear (350) is engaged with the first gear (310) by the lifting cylinder (360), the first gear (310) stops rotating in the circumferential direction and can move in the axial direction, so that the second step surface (321) rotates and raises the first step surface (311) engaged with the second step surface (321), thereby allowing the grill plate (100) to be raised.

[0038] In addition, each of the first and second stepped surfaces (311, 321) may correspond to each other to form at least 3 to 7 steps inclined thereto.

[0039] Additionally, the heat source unit (500) may include a first heat source module (510) installed in the center of the heat source unit (500), a second heat source module (520) installed side by side on one side of the first heat source module (510), a third heat source module (530) installed side by side on the other side of the first heat source module (510), a first heat source button (540) for turning the first heat source module (510) on / off, a second heat source button (550) for turning the first and second heat source modules (510, 520) on / off simultaneously, and a third heat source button (560) for turning the first to third heat source modules (510, 520, 530) on / off simultaneously.

[0040] In addition, the first to third heat source buttons (540, 550, 560) may be arranged adjacently and continuously on the heat source section or standing section and electrically connected to the first to third heat source modules (510, 520, 530).

[0041] In addition, each of the first to third heat source modules (510, 520, 530) can emit far-infrared rays by passing through a ceramic grill (570) located below.

[0042] In addition, it may further include a ventilation section (600) installed along the longitudinal direction on both sides of the heat source section (500).

[0043] Additionally, the ventilation unit (600) may include an activated carbon filter (610) attached to both sides of the heat source unit (500), a ventilation passage (620) that enters the activated carbon filter (610) and guides the flow of air, and a ventilation fan (630) installed at one end of the ventilation passage (620).

[0044] Additionally, the fuel tank (710) housed inside the above-mentioned standing part (400) may further include a fuel part (700) that supplies fuel to the heat source part (500).

[0045] In addition, the fuel section (700) can transfer heat formed on the surface of the upright section (400) to the fuel tank (710) through a heat transfer plate (720) in order to prevent the fuel tank (710) from becoming cold as it consumes fuel.

[0046] In addition, it may further include a cooking section (800) that is recessed to a predetermined depth above the heat source section (500) to form a space.

[0047] Additionally, it may further include a control unit (900) formed on one side of the main base (200) to control the rotation speed and lifting height of the grill plate (100) in a button-like manner.

[0049] Then, the configuration and operation of the far-infrared multi-grill device (10) according to the embodiments of the present invention will be described in detail as follows.

[0050] The far-infrared multi-grill device (10) proposed by the present invention is a grill device (10) with technology that is significantly improved compared to the conventional one, such as being able to adjust the height of the grill plate in steps (#3 to #7), conveniently configuring the heat source unit for easy operation, and inhaling and discharging the smell or smoke of the grilled meat. As shown in FIG. 1, etc., it may include a grill plate (100), a main base (200), a driving unit (300), an upright unit (400), and a heat source unit (500).

[0052] The grill plate (100) has various shapes such as a circle, an oval, or a polygon, and forms a plate-like shape of a predetermined thickness that allows meat to be grilled well.

[0053] In particular, the grill plate (100) has a discharge port (110) formed in the center downward to form a discharge path through which oil and other substances from the meat can be discharged, and a first gear (310) of a driving part (300) surrounding the discharge port (110) is engaged so that it can be artificially rotated or raised and lowered.

[0054] Meanwhile, the grill plate (100) is formed with a downward slope so that its upper surface faces the discharge port (110), and oil is discharged through the discharge port (110) to a slide-type oil tray (210) formed at the bottom of the main base (200).

[0056] The main base (200) is a sturdy flat plate member fixed to the ground, and while supporting the grill plate (100), a space is formed inside in which a driving unit (300) can be mounted, and at the same time, an oil tray (210) is formed through a central passage connected to the discharge port (110) of the grill plate (100).

[0057] That is, as illustrated in FIGS. 1 to 3, the main base (200) is a flat plate member of a predetermined height with a hollow interior, providing a space for the driving unit (300) to operate, and at the same time, an oil tray (210) connected to the discharge port (110) is formed in the longitudinal direction so that oil from meat flowing out from the grill plate (100) flows downward along the discharge port (110) and is temporarily stored in the oil tray (210), after which the oil tray (210) can be slid out and discharged to the outside.

[0059] The driving unit (300) is a device capable of rotating or raising the grill plate (100), as illustrated in detail in FIGS. 3 to 6, etc.

[0060] That is, the driving unit (300) is built into the main base (200) and is a means to rotate or raise the grill plate (100), and includes a first gear (310), a second gear (320), a third gear (330), a motor (340), an elevator gear (350), and an elevator cylinder (360), etc.

[0061] Here, the first gear (310) wraps around the discharge port (110) and has gear-shaped teeth formed along its outer surface, which are fixed by engaging with the elevator gear (350), but can be raised and lowered in the axial direction.

[0062] In particular, as illustrated in FIG. 4, the first gear (310) forms a first stepped surface (311) and a first inclined surface (312) that repeatedly rise and fall in an axial direction along the circumferential direction, so that unless it is engaged with the elevator gear (350), the first stepped surface (311) comes into close contact with the second stepped surface (321) of the second gear (320) and rotates according to the rotation of the second gear (320).

[0063] Additionally, when the first gear (310) is engaged with the elevator gear (350), circumferential rotation is not possible, but axial upward movement is possible. Therefore, as the second step surface (321) engaged with the first step surface (311) rotates, the first step surface (311) cannot rotate in the circumferential direction and is pushed in the axial direction to move up and down, thereby allowing the grill plate (100) to be raised.

[0064] The second gear (320) is formed to be separated axially from the first gear (310) and is a gear capable of providing rotational force or lifting force to the first gear (310).

[0065] That is, as illustrated in FIG. 4, the second gear (320) can provide rotational force or lifting force to the first gear (310) by forming a second stepped surface (321) and a second inclined surface (322) on the upper part of the second gear (320) that repeatedly rises and falls in an axial direction along the circumferential direction in correspondence with the first gear (310).

[0066] Additionally, the second gear (320) has a conical gear formed along its lower circumference and is meshed with the third gear (320) as a bevel gear to receive rotational power from the third gear (320).

[0067] Meanwhile, the first and second step surfaces (311, 321) are each formed to correspond to each other, and at least 3 to 7 steps may be formed at an angle to adjust the lifting height of the grill plate (100) in steps. At this time, if there are 2 steps each for the first and second step surfaces (311, 321), the deviation in lifting height is too severe, and if there are more than 7 steps, the step-by-step lifting height is too fine and inconvenient to operate.

[0068] The third gear (330) is a bevel gear with a gear mesh that can rotate by interlocking with the second gear (320), and can transmit rotational power from the motor (340) by interlocking with the second gear (320) at 90°.

[0069] The motor (340) is a power source that is connected to the rotation shaft of the third gear (330) and can provide rotational power to the third gear (330), and may be a stepper motor that is easy to control. In addition, the motor (340) is equipped with a reduction gear so that it can reduce speed to an appropriate speed and achieve low-speed rotation.

[0070] The elevator gear (350) is a member that guides the first gear (310) by having gear-shaped teeth formed along its outer surface to prevent rotation in the circumferential direction of the first gear (310) and to allow it to move up and down in the axial direction. That is, the elevator gear (350) does not necessarily have to have a gear-shaped outer surface; it can be any member that enables axial movement while preventing rotation in the circumferential direction of the first gear (310).

[0071] The lifting cylinder (360) is an actuator capable of moving the lifting gear (350) back and forth to come into contact with or separate from the first gear (310), and can provide linear power capable of controlling the rotation and lifting of the first gear (310) as needed.

[0073] The standing member (400) is a vertical member formed vertically on one side of the main base (200) and firmly fixed to the main base (200), having an empty space formed inside to accommodate the fuel member (700). Additionally, the standing member (400) supports the heat source member (500) upwardly and can be firmly fixed so that the heat source member (500) can stably and sufficiently irradiate toward the grill plate (100).

[0075] The heat source part (500) is formed horizontally so that it protrudes laterally from the upper part of the standing part (400) toward the grill plate (100), and thus is a heat source device capable of emitting far-infrared rays toward the grill plate (100).

[0076] In particular, the heat source unit (500) can be configured to be subdivided into first to third heat source modules (510, 520, 530) as shown in FIG. 7, etc., in order to emit heat differently depending on the amount or type of meat to be grilled.

[0077] That is, the heat source unit (500) proposed by the present invention includes a first heat source module (510) installed in the center, a second heat source module (520) installed parallel to one side of the first heat source module (510), and a third heat source module (530) installed parallel to the other side of the first heat source module (510).

[0078] In addition, the first heat source button (540) can turn the first heat source module (510) on / off as shown in FIG. 7 (a).

[0079] Additionally, the second heat source button (550) can turn the first and second heat source modules (510, 520) on / off simultaneously, as shown in FIG. 7 (b).

[0080] In addition, the third heat source button (560) can simultaneously turn on / off the first to third heat source modules (510, 520, 530) as shown in FIG. 7 (b).

[0081] Meanwhile, the first to third heat source buttons (540, 550, 560) can be arranged adjacently and continuously on the heat source section (500) or the standing section (400) and are electrically connected to the first to third heat source modules (510, 520, 530).

[0082] At this time, each of the first to third heat source modules (510, 520, 530) can emit far-infrared rays by passing through a ceramic grill (570) located below, as shown in FIG. 8, so that high-quality meat placed on the grill plate (100) can be grilled deliciously.

[0083] For reference, each of the first to third heat source modules (510, 520, 530) can be individually ignited and heated by a burner after receiving fuel (butane gas) from the fuel unit (700).

[0085] The ventilation unit (600) is a ventilation device installed along the longitudinal direction on both sides of the heat source unit (500) for removing the smell or smoke of meat being grilled on the grill plate (100).

[0086] Additionally, the ventilation unit (600) may include a filter (610), a ventilation passage (620), and a ventilation fan (630), as illustrated in FIG. 9 and FIG. 10, etc.

[0087] Here, the filter (610) is a fine mesh attached to both sides of the heat source (500) and is an activated carbon filter beneficial to the human body that can filter out meat odors or smoke and purify them. At this time, the activated carbon filter is an adsorbent made by activating carbonaceous raw materials, and has a large surface area so it can effectively adsorb harmful substances.

[0088] Additionally, the ventilation passage (620) can form a flow path along the empty space inside the heat source part (500) to guide the flow of air entering the filter (610).

[0089] Additionally, a ventilation fan (630) is installed at one end of the ventilation passage (620) to purify odors or smoke that have entered the ventilation passage (620) and discharge them to the outside.

[0091] The fuel section (700) is formed inside the standing section (400) and is a means to supply fuel (butane gas, etc.) to the heat source section (500) along the standing section (400).

[0092] Additionally, the fuel section (700) may include a fuel tank (710) accommodated inside the upright section (400), a heat transfer plate (720) that transfers a heat source formed on the surface of the upright section (400) to the fuel tank (710), and a fuel opening / closing door (730) that can open / close the outer surface of the upright section (400).

[0093] In particular, the heat transfer plate (720) proposed by the present invention is in the shape of a strip or band, with one side connected to the surface of the upright portion (400) and the other side in contact with the surface of the fuel tank (710) to prevent the fuel tank (710) from becoming cold as it consumes fuel (gas, etc.). This is because if the temperature of the fuel tank (710) decreases, the gas (fuel) energy decreases, making it impossible to fully use the fuel (gas, etc.) remaining in the fuel tank (710) and preventing the heat from being maintained evenly and continuously. At this time, the heat transfer plate (720) may be made of copper, which has a high thermal conductivity.

[0095] As illustrated in FIG. 9, the cooking section (800) may be recessed to a predetermined depth above the heat source section (500) to form a receiving space, and may be a member on which a container such as a pot or meat cooked on a grill plate (100) can be placed, thereby maximizing the use of residual heat generated from the heat source section (500).

[0097] As illustrated in FIGS. 1 and 2, the control unit (900) is a controller formed on one side of the main base (200) in a button-like manner and capable of controlling the rotation speed and lifting height of the grill plate (100) through the driving unit (300). That is, the control unit (900) may include a power button, a rotation speed button, a lifting button, a timer for adjusting the rotation time, etc.

[0098] Meanwhile, the control unit (900) may be powered by a built-in battery or rechargeable battery, or may use an external commercial power source by reducing the voltage.

[0099] That is, the control unit (900) is a device that controls through a control signal and includes a built-in computer processing unit and an externally exposed display, and can control the motor (340) and lifting cylinder (360), etc. of the driving unit (300) according to a set program of the computer processing unit to adjust the rotation speed and lifting height of the grill plate (100).

[0100] In addition, the control unit (900) can control the heat source unit (500), ventilation unit (600), and fuel unit (700), etc., to adjust the heat source intensity, ventilation level, fuel supply amount, etc., in conjunction with the driving unit (300).

[0102] Thus, the far-infrared multi-grill device (10) according to the embodiments of the present invention can be expected to have the following effects.

[0103] According to the present invention, there is an advantage in that the height of the grill plate (100) can be adjusted in steps (#3 to #7) and the rotation of the grill plate (100) can be combined to grill meat in an optimal state.

[0104] In addition, the heat source unit (500) is modularized, making it simple and convenient to operate, and has the advantage of allowing selective irradiation on the desired grill plate (100).

[0105] In addition, there is an advantage in that the smell or smoke of the meat can be absorbed and purified and discharged through the ventilation unit (600).

[0106] In addition, there is an advantage in that the fuel section (700) can be improved to consume even the fuel (gas, etc.) remaining in the fuel tank (710).

[0108] The above description is merely an illustrative explanation of the technical concept of the present invention, and those skilled in the art to which the present invention pertains will be able to make various modifications, changes, and substitutions within the scope of the essential characteristics of the present invention without departing from its nature.
