Description

Technical Field

[0001] The present invention relates to the technical field of barbecue devices, and particularly to a barbecue grill adjustment mechanism and a far-infrared barbecue device. Background Art

[0002] Cooking methods for meats such as beef and pork include boiling or frying, but ordinary restaurants or families often use the method of grilling seasoned meats. In the past, the method of roasting meat was with charcoal. It is well known that the meat roasted with charcoal tastes good because of the far-infrared rays emitted by the charcoal. So-called far-infrared refers to the infrared region with relatively long wavelengths in infrared rays. Compared with infrared rays in other regions, it contains more heat. When roasting meat, there are lights of various wavelengths in the fire, and the heating is mainly responsible for the light in the infrared region. However, in the infrared region, the light in the region with shorter wavelengths will cause high temperatures. Although a lot of meat will be charred during the cooking process, the far-infrared rays have relatively long wavelengths in the infrared region, and its advantage is that the temperature is relatively low but the heat is abundant, and the meat can be cooked without charring the meat.

[0003] That is to say, since charcoal releases more far-infrared rays than ordinary fire, it mainly plays the role of cooking rather than charring. Although the meat is not well burned, it is cooked both outside and inside. In addition, when using charcoal, since the meat is cooked using the radiant heat of the charcoal, the juice of the meat will not evaporate, so it has the advantage of being able to feel the rich flavor of the meat.

[0004] However, since using charcoal to roast meat is a direct-fire method, there are problems that some meat will produce smoke when burning. Moreover, the charcoal is prepared outdoors and then put into the stove and carried to the dining table, and then processed after the meat is roasted. Not only is the process cumbersome, but there are also potential accident hazards such as being scalded or having a fire during the movement.

[0005] Therefore, many people use gas to directly roast meat. However, although the method of roasting meat with gas is convenient, there are also problems with roasting meat. In addition, since the meat is cooked with convective heat instead of the radiant heat of far-infrared rays, the juice of the meat will evaporate, thus losing the rich flavor of the meat.

[0006] In order to solve the above problems, a roasting oven has been proposed in which the flame generated by a gas burner passes through a furnace that emits far-infrared rays, so as to roast the meat on the furnace using the far-infrared rays generated by the germanium-containing furnace. However, the disadvantages of this roasting oven are low heat transfer rate, the need to ignite the gas heater and heat for a quite long time before roasting meat, and weak strength, being easily broken by impact. On the other hand, even when using the furnace, there is also such a problem that when the gas burned from the gas burner is directly delivered to the furnace where the meat is placed, the furnace will be quickly heated and cause the meat to burn.

[0007] At present, although there are also barbecue devices that use far-infrared to cook food, their structures are rigid and cannot adjust the height of the baking tray according to the needs of users. Even if there is a technology for adjusting the height, the structural design is relatively complex and the stability is not good. Summary of the Invention

[0008] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a barbecue baking tray adjusting mechanism and a far-infrared barbecue device, aiming to improve the convenience and stability of using the barbecue device.

[0009] To achieve the above purpose, the present invention adopts the following technical solutions:

[0010] On the one hand, the present invention provides a barbecue baking tray adjusting mechanism, including a baking tray body and a driving component. The baking tray body is driven by the driving component to rotate and lift. The driving component includes an upper gear, a lower gear, a side gear, a lifting auxiliary gear, a first power component that provides power to the side gear, and a second power component that provides power to the lifting auxiliary gear. The bottom circumference of the upper gear is provided with a first-stage jaw surface and a first inclined surface. The first-stage jaw surface repeatedly inclines and rises and falls axially along the circumferential direction. The top circumference of the lower gear is provided with a second-stage jaw surface and a second inclined surface. The second-stage jaw surface repeatedly inclines and rises and falls axially along the circumferential direction. When the lower gear meshing with the side gear rotates along the circumferential direction under the action of the first power component, the first-stage jaw surface meshes with the second-stage jaw surface, so that the upper gear rotates circumferentially and drives the baking tray body to rotate at the same time. When the lifting auxiliary gear approaches and contacts the upper gear through the second power component, and the lower gear rotates along the circumferential direction, the upper gear is prevented from rotating circumferentially, and at the same time, the first-stage jaw surface meshing with the second-stage jaw surface pushes along the axial direction of the upper gear, so that the baking tray body lifts.

[0011] Further, the first-stage jaw surface and the second-stage jaw surface have at least 3 to 7 inclined steps.

[0012] Further, a push rod is provided between the second power component and the lifting auxiliary gear. The push rod advances or retreats under the action of the second power component, so that the lifting auxiliary gear approaches or moves away from the upper gear.

[0013] Further, it further includes a positioning member. The positioning member is vertically arranged. The upper end of the positioning member is connected to the bottom of the baking tray body. The upper gear and the lower gear are movably sleeved on the positioning member.

[0014] On the other hand, the present invention also provides a far-infrared barbecue device, which includes a base, a column, a far-infrared heating part, and the above-mentioned barbecue grill adjusting mechanism. The grill body is placed above the base, the driving assembly is built in the base, the column is arranged on one side of the base, and the far-infrared heating part protrudes laterally from the upper end of the column and faces the grill body.

[0015] Further, the far-infrared heating part includes a plurality of heat source modules and a corresponding number of heat source buttons. The plurality of heat source modules are arranged in parallel side by side, and the heat source buttons are used to control the opening and closing of the heat source modules.

[0016] Further, it also includes a fuel tank arranged in the column. The fuel tank includes a fuel assembly for supplying fuel to the far-infrared heating part. The fuel assembly includes a heat transfer plate, and the heat transfer plate transfers the heat formed on the surface of the column to the fuel tank.

[0017] Further, it also includes a cooking part, which is embedded above the far-infrared heating part, and the cooking part is provided with a receiving space.

[0018] Further, it also includes a ventilation part, which includes a filter, a ventilation channel, and a fan. The filter is arranged on both sides in the length direction of the far-infrared heating part. The ventilation channel is used to guide the air entering the filter, and the fan is arranged on one side of the ventilation channel to discharge the air entering the ventilation channel to the outside.

[0019] Further, it also includes a control unit arranged on the base.

[0020] The beneficial effects of the present invention compared with the prior art are as follows: A barbecue grill pan adjusting mechanism includes a grill pan body and a driving assembly. The grill pan body is driven by the driving assembly to rotate and lift. The driving assembly includes an upper gear, a lower gear, a side gear, a lifting auxiliary gear, a first power member for providing power to the side gear, and a second power member for providing power to the lifting auxiliary gear. The bottom circumference of the upper gear is provided with a first-stage jaw surface and a first inclined surface. The first-stage jaw surface repeatedly inclines upward and downward in the axial direction along the circumferential direction. The top circumference of the lower gear is provided with a second-stage jaw surface and a second inclined surface. The second-stage jaw surface repeatedly inclines upward and downward in the axial direction along the circumferential direction. When the lower gear engaged with the side gear rotates in the circumferential direction under the action of the first power member, the first-stage jaw surface meshes with the second-stage jaw surface, so that the upper gear rotates circumferentially and drives the grill pan body to rotate. When the lifting auxiliary gear approaches and contacts the upper gear through the second power member and the lower gear rotates in the circumferential direction, the upper gear is prevented from rotating in the circumferential direction, and at the same time, the first-stage jaw surface engaged with the second-stage jaw surface pushes along the axial direction of the upper gear, so that the grill pan body is lifted. Through the designed driving assembly of the present invention, the height of the grill pan body can be adjusted in stages, and at the same time, the rotation of the grill pan body is taken into account, which is convenient for users to adjust and use, enabling users to roast meat in the best state and improving the user experience. At the same time, the driving assembly realizes the rotation and lifting of the grill pan body only by the cooperation of a small number of gears, with a simple and ingenious structure, greatly reducing the manufacturing cost and production difficulty.

[0033] As Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a barbecue grill pan adjusting mechanism 1, including a grill pan body 11 and a driving assembly. The grill pan body 11 is driven by the driving assembly to rotate and lift. The driving assembly includes an upper gear 12, a lower gear 13, a side gear 14, a lifting auxiliary gear, a first power member 15 that provides power to the side gear 14, and a second power member that provides power to the lifting auxiliary gear. A first-stage jaw surface 121 and a first inclined surface 122 are circumferentially provided at the bottom of the upper gear 12. The first-stage jaw surface 121 repeatedly inclines and rises and falls axially in the circumferential direction. A second-stage jaw surface 131 and a second inclined surface 132 are circumferentially provided at the top of the lower gear 13. The second-stage jaw surface 131 repeatedly inclines and rises and falls axially in the circumferential direction. When the lower gear 13 engaged with the side gear 14 rotates in the circumferential direction under the first power member 15, the first-stage jaw surface 121 meshes with the second-stage jaw surface 131, so that the upper gear 12 rotates circumferentially and drives the grill pan body 11 to rotate. When the lifting auxiliary gear approaches and contacts the upper gear 12 through the second power member, and the lower gear 13 rotates in the circumferential direction, the upper gear 12 is prevented from rotating in the circumferential direction, and at the same time, the first-stage jaw surface 121 engaged with the second-stage jaw surface 131 is pushed in the axial direction of the upper gear 12, so that the grill pan body 11 is lifted.

[0034] The baking tray body 11, as a component directly bearing food for baking, can be designed in various shapes such as circular and square according to actual needs. The material can be selected as a metal material with good thermal conductivity and high temperature resistance, such as stainless steel, to ensure uniform heating during baking and guarantee the baking effect of food. There is a discharge port formed downward in the center of the baking tray to form a discharge channel through which oil in the meat and the like can be discharged through the discharge port.

[0035] The driving component is the core component for realizing the rotation and lifting functions of the baking tray body 11. It consists of an upper gear 12, a lower gear 13, a side gear 14, a lifting auxiliary gear, a first power component 15 and a second power component. The upper gear 12 is located below the baking tray body 11, and the lower gear 13 is located below the upper gear 12. The second-stage jaw surface 131 and the second inclined surface 132 circumferentially arranged at the top of the lower gear 13 correspond to the first-stage jaw surface 121 and the first inclined surface 122 of the upper gear 12. The second-stage jaw surface 131 also repeatedly inclines upward and downward axially along the circumferential direction, and matches the number and shape of the inclined steps of the first-stage jaw surface 121.

[0036] Preferably, the first-stage jaw surface 121 and the second-stage jaw surface 131 have at least 3 to 7 inclined steps, and such a design can achieve hierarchical adjustment of the height of the baking tray body 11.

[0037] It should be explained that both the first-stage jaw surface 121 and the second-stage jaw surface 131 have an inclined surface structure that repeatedly inclines upward and downward axially along the circumferential direction. When the second gear rotates, the acting force between the second-stage jaw surface 131 and the first-stage jaw surface 121 is along the normal direction of their contact surface. Since this normal direction does not coincide with the axial or circumferential direction of the first gear, this force can be decomposed into two component forces. One is the component force along the circumferential direction of the first gear, which is used to drive the first gear to rotate; the other is the component force along the axial direction of the first gear. Therefore, in the case of the first-stage jaw surface 121 and the second-stage jaw surface 131, the acting force of the second-stage jaw surface 131 on the first-stage jaw surface 121 is similar to the supporting force of an inclined plane on an object, except that the "inclined plane" here is distributed around the circumference of the gear, so the generated axial component force will be along the axial direction of the first gear. As the second gear continues to rotate, the second-stage jaw surface 131 continuously contacts different positions of the first-stage jaw surface 121, and such an axial component force will be generated each time of contact. Since these contact points appear sequentially along the circumference, this axial component force persists during the rotation of the second gear, and this axial component force will push the first-stage jaw surface 121, and then push the first gear to move axially. Without other restrictions, the first gear will move axially under the action of this axial component force, thereby realizing the lifting of the baking tray body 11.

[0038] The side gear 14 functions to transmit power and meshes with the lower gear 13. The first power component 15, as the power source for driving the side gear 14, can be a motor, such as a small DC motor. The motor is connected to the side gear 14 through the output shaft. When the motor starts, the output shaft drives the side gear 14 to rotate, and then drives the meshing lower gear 13 to rotate in the circumferential direction.

[0039] The lifting auxiliary gear and the second power component jointly control the lifting of the baking tray. The second power component can be a cylinder or an electric push rod. Taking the cylinder as an example, the cylinder is connected to the air source through an air pipe. When it is necessary to control the movement of the lifting auxiliary gear, by controlling the supply and exhaust of the air source, the piston rod of the cylinder is extended and retracted. A push rod is provided between the piston rod of the cylinder and the lifting auxiliary gear. The push rod advances or retreats under the action of the piston rod of the cylinder, so as to realize the approach or separation of the lifting auxiliary gear from the upper gear 12.

[0040] When it is necessary to rotate the baking tray body 11, start the first power component 15, that is, the motor runs to drive the side gear 14 to rotate. The side gear 14 drives the lower gear 13 to rotate in the circumferential direction. At this time, the first-stage jaw surface 121 meshes with the second-stage jaw surface 131. The rotational force of the lower gear 13 is transmitted to the upper gear 12 through the meshing of the two-stage jaw surfaces, causing the upper gear 12 to rotate circumferentially, and then driving the baking tray body 11 to rotate.

[0041] When it is necessary to adjust the height of the baking tray body 11, start the second power component. Taking the cylinder as an example, the cylinder pushes the push rod to make the lifting auxiliary gear approach and contact the upper gear 12. At this time, the lifting auxiliary gear generates a force that prevents the upper gear 12 from rotating circumferentially. At the same time, the lower gear 13 continues to rotate in the circumferential direction under the drive of the first power component 15. Since the circumferential rotation of the upper gear 12 is restricted, the first-stage jaw surface 121 meshing with the second-stage jaw surface 131 will push along the axial direction of the upper gear 12. As the lower gear 13 continues to rotate, the first-stage jaw surface 121 continuously moves along the axial direction of the upper gear 12, thereby realizing the lifting of the baking tray body 11.

[0042] Through the designed drive assembly, the height of the baking tray body 11 can be adjusted in stages, while taking into account the rotation of the baking tray body 11, meeting the baking requirements of different foods, facilitating the user to adjust and use, and greatly improving the user experience. The drive assembly realizes the rotation and lifting of the baking tray body 11 only by the cooperation of a small number of gears, with a simple and ingenious structure. Compared with the traditional complex baking tray adjustment structure, the manufacturing cost and production difficulty are greatly reduced, which is beneficial to the large-scale production and market promotion of the product.

[0043] In one embodiment, the barbecue grill pan adjusting mechanism 1 further includes a positioning member. The positioning member is vertically arranged, and the upper end of the positioning member is connected to the bottom of the grill pan body 11. The upper gear 12 and the lower gear 13 are movably sleeved on the positioning member.

[0044] The positioning member is of a cylindrical structure. The upper end of the positioning member is connected to the bottom of the grill pan body 11, and the connection method can be a clamping method or an opening matching method to facilitate disassembly and installation. The upper gear 12 and the lower gear 13 are movably sleeved on the positioning member. This design enables the gears to rotate and axially move flexibly on the positioning member. The positioning member acts as a track and support here, restricting the movement trajectory of the gears so that they can only move in a specific direction.

[0045] The setting of the positioning member improves the stability of the entire adjusting mechanism. During the rotation and lifting of the grill pan body 11, the positioning member can effectively prevent the upper gear 12 and the lower gear 13 from shifting horizontally, ensuring that the meshing between the gears is always in good condition. For example, when the grill pan body 11 rotates at a high speed, without the positioning member, the gears may shift horizontally due to factors such as centrifugal force, resulting in poor meshing and affecting the normal rotation of the grill pan. With the positioning member, this situation can be well avoided, ensuring the stable operation of the device. Secondly, the positioning member helps to improve the lifting accuracy of the grill pan body 11. Since the upper gear 12 and the lower gear 13 axially move along the positioning member, the positioning member can accurately guide their movement, enabling the grill pan body 11 to accurately reach the set height position during the lifting process. For example, when baking ingredients of different thicknesses, it is necessary to accurately adjust the height of the grill pan, and the positioning member can ensure the accuracy of each adjustment, thereby improving the baking effect.

[0046] As Figure 1 and Figure 2 shown, the embodiment of the present invention further provides a far-infrared barbecue device, which includes a base 2, a column 3, a far-infrared heating part 4, and the above-mentioned barbecue grill pan adjusting mechanism 1. The grill pan body 11 is placed above the base 2, the driving assembly is built in the base 2, the column 3 is arranged on one side of the base 2, and the far-infrared heating part 4 protrudes laterally from the upper end of the column 3 and faces the grill pan body 11.

[0047] The base 2 serves as the basic support component of the entire barbecue device. Inside the base 2, a special space is reserved for placing the driving assembly. To facilitate the installation and maintenance of the driving assembly, the base 2 can be designed as a detachable structure, such as assembling the various parts of the base 2 together by means of bolt connection. In this way, when the driving assembly fails, it is convenient for maintenance personnel to disassemble and overhaul.

[0048] A sliding oil storage device is also provided on the base 2. A through hole is provided through the center of the positioning member. The upper end of the through hole communicates with the discharge port of the baking tray body 11, and the lower end of the through hole communicates with the sliding oil storage device. The oil in the baking tray body 11 is discharged to the sliding oil storage device through the through hole of the positioning member and is temporarily stored in the sliding oil storage device. Then, the sliding oil storage device is slid out and cleaned to the outside.

[0049] In one embodiment, the far-infrared heating part 4 includes a plurality of heat source modules and a corresponding number of heat source buttons 41. The plurality of heat source modules are arranged in parallel side by side, and the heat source buttons 41 are used to control the opening and closing of the heat source modules.

[0050] In this embodiment, there are three heat source modules, namely the first heat source module, the second heat source module installed parallel to one side of the first heat source module, and the third heat source module installed parallel to the other side of the first heat source module. There are three heat source buttons 41, namely the first heat source button 41 for opening or closing the first heat source module, the second heat source button 41 for simultaneously opening or closing the first heat source module and the second heat source module, and the third heat source button 41 for simultaneously opening or closing the first heat source module, the second heat source module and the third heat source module.

[0051] The heat source module uses a ceramic grille as the component for emitting far-infrared rays. The ceramic grille has good high-temperature resistance and far-infrared emission performance, and can stably transfer heat to food in the form of far-infrared rays. The setting of the heat source buttons 41 is closely matched with the heat source modules, realizing diversified control functions. The first heat source button 41 is used to independently control the opening or closing of the first heat source module. When baking smaller foods, such as chicken wings, it may only be necessary to turn on the first heat source module to meet the baking requirements, which can avoid energy waste and accurately control the baking temperature. The second heat source button 41 can simultaneously open or close the first heat source module and the second heat source module. When baking medium-sized foods, such as steaks, turning on the first heat source and the second heat source module can provide sufficient heat to quickly cook the steak while ensuring the taste of the steak. The third heat source button 41 is used to simultaneously control the opening and closing of the three heat source modules. When baking a large amount of food or needing to quickly increase the baking temperature, such as baking mutton skewers for multiple people, turning on the three heat source modules simultaneously can speed up the baking speed and improve the baking efficiency.

[0052] In one embodiment, the far-infrared barbecue device further includes a fuel tank provided in the column 3. The fuel tank includes a fuel component for supplying fuel to the far-infrared heating part 4. The fuel component includes a heat transfer plate, and the heat transfer plate transfers the heat formed on the surface of the column 3 to the fuel tank.

[0053] The fuel tank is a device that can supply fuel (such as butane gas) to the far-infrared heating part 4 along the column 3.

[0054] In addition to the heat transfer plate, the fuel assembly further includes a fuel switch door that can open and close the outer side of the column 3.

[0055] The heat transfer plate can be made of copper material with high thermal conductivity. The heat transfer plate is in a strip or ribbon shape, one side of which is connected to the surface of the column 3, and the other side is in contact with the surface of the fuel tank to prevent the fuel tank from becoming low-temperature as the fuel (such as gas) is consumed. When the temperature of the fuel tank decreases, the energy of the gas (fuel) decreases because the remaining fuel cannot be fully utilized and the heat cannot be maintained evenly and continuously.

[0056] In one embodiment, the far-infrared barbecue device further includes a cooking section 5. The cooking section 5 is embedded above the far-infrared heating section 4. The cooking section 5 is provided with an accommodation space for placing containers such as pots or cooked meat on the baking tray body 11. The provided ridge can maximize the utilization of the waste heat generated from the far-infrared heating section 4 and the like.

[0057] In one embodiment, the far-infrared barbecue device further includes a ventilation section 6, a ventilation filter, a ventilation channel, and a fan. The filter is provided on both sides in the length direction of the far-infrared heating section 4. The ventilation channel is used to guide the air entering the filter. The fan is provided on one side of the ventilation channel to discharge the air entering the ventilation channel to the outside.

[0058] The filter is a micro filter attached to both sides of the far-infrared heating section 4 and is an activated carbon filter beneficial to the human body, which can purify by capturing the smell of meat or smoke. At this time, the activated carbon filter element is an adsorbent made by activating a carbonaceous raw material, and it has a large surface area and can well adsorb harmful substances.

[0059] In one embodiment, it further includes a control unit 7 provided on the base 2.

[0060] The control unit 7 is formed in the front of the base 2 in the form of buttons. The driving assembly is controlled by the control unit 7 to adjust the rotation speed, lifting height, etc. of the baking tray body 11. The control unit 7 includes a power button, a rotation speed button, a lifting button, and a timer for adjusting the rotation time.

[0061] The control unit 7 can be powered by a built-in battery or a rechargeable battery, or can be powered by an external public power supply.

[0062] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
