Description

Technical Field

[0001] The present invention relates to the technical field of heating devices, and more particularly to a heating device for cooking steaks. Background Art

[0002] In daily life, traditional cooking methods such as frying pans and ovens used to process steaks often make it difficult to accurately control the temperature and time, resulting in the doneness of the steaks being difficult to grasp, and it is easy to have the situation of being overcooked on the outside and raw on the inside or not cooked enough. The emergence of steak machines has reduced the difficulty of people cooking steaks, and people can conveniently fry steaks through steak machines.

[0003] However, most of the existing steak machines on the market are flip-top structures, and the double-sided flip-top clamping method is adopted. Manually buckle a second heating plate that can be actively opened on the steak to be fried, so that both sides of the steak can be heated simultaneously. However, this flip-top clamping method can only be applied to steaks within a certain thickness range. Steaks with too small a thickness may not be clamped, resulting in one side being cooked while the other side is still raw. Steaks with too large a thickness may not have sufficient clamping area, resulting in one side being burnt while the other side is still raw, and it is impossible to adapt to cooking steaks of more thickness sizes.

[0004] In view of the above deficiencies, we need to develop a heating device for cooking steaks to meet the usage requirements of the majority of users. Summary of the Invention

[0005] In view of the above-mentioned problems existing in the existing steak machines, such as being unable to adapt to cooking steaks of more thickness sizes, the technical solution adopted by the present invention to solve its technical problems is as follows: A heating device for cooking steaks, comprising a fixed base, a movable flip-top and a lifting transmission mechanism. The movable flip-top is hinged and covers the fixed base to form a heating and cooking inner cavity. The lifting transmission mechanism is installed at the bottom of the heating and cooking inner cavity. A first heating plate is installed at the top of the heating and cooking inner cavity, and a second heating plate is installed at the top of the lifting transmission mechanism. The lifting transmission mechanism can drive the second heating plate to approach or move away from the first heating plate.

[0006] For a heating device for cooking steaks as described above, the first heating plate is buckled and hung on the inner cavity side hole of the movable flip-top through the back of the plate. An elastic member for reducing impact and resetting is installed between the first heating plate and the movable flip-top. After the first heating plate is pressed against the micro-switch of the movable flip-top, the micro-switch triggers the lifting transmission mechanism to drive the second heating plate to descend.

[0007] A heating device that can be used for cooking steak as described above, a heat insulation cover for heat preservation and insulation is installed on the back of the first heating plate, and / or a heat insulation cover for heat preservation and insulation is installed on the back of the second heating plate; a heating element for heating the cooking temperature is installed inside the heat insulation cover.

[0008] A heating device that can be used for cooking steak as described above, an external machine base support leg for supporting the force on the flip cover is installed at a position of the fixed machine base close to the hinge of the movable flip cover. The external machine base support leg extends from the hinge of the movable flip cover towards the bottom, and a support leg stable plane is provided at the bottom.

[0009] A heating device that can be used for cooking steak as described above, the lifting transmission mechanism includes a fixing member for restricting the installation position, a transmission component installed on the fixing member, and a driver for providing power. The driver drives the transmission component to drive the second heating plate to approach or move away from the first heating plate in the vertical direction.

[0010] A heating device that can be used for cooking steak as described above, the fixing member includes a first fixing bracket and a second fixing bracket. A first balance support rod and a second balance support rod are installed between the first fixing bracket and the second fixing bracket and are respectively arranged in parallel on the left and right sides of the transmission member. The first balance support rod passes through the left directional hole of the transmission member, and the second balance support rod passes through the right directional hole of the transmission member. The transmission member moves directionally along the first balance support rod and the second balance support rod.

[0011] A heating device that can be used for cooking steak as described above, the transmission component includes a transmission shaft, a transmission member, a connecting rod member, and a supporting rod. The transmission member is installed on the transmission shaft. One end of the connecting rod member is hinged to the transmission member, and the other end of the connecting rod member is hinged to a supporting bracket installed at the bottom of the second heating plate through the supporting rod. The transmission shaft rotates and drives the transmission member to move axially. The transmission member drives the supporting bracket to rise or fall through the connecting rod member and the supporting rod.

[0012] A heating device that can be used for cooking steak as described above, the transmission component includes two transmission members with opposite internal thread rotation directions. The outer surface of the transmission shaft is provided with an external thread adapted to the internal thread. The transmission shaft rotates and drives the two transmission members to approach or move away from each other through screw transmission.

[0013] A heating device that can be used for cooking steak as described above, one end of the connecting rod member away from the driving member is higher than the end close to the driving member. When the distance between the two driving members is the minimum value within the stroke range, a connecting rod horizontal angle a is formed between the connecting rod member and the horizontal plane where the central axis of the transmission shaft is located, and the angle of the connecting rod horizontal angle a is greater than 0.5 degrees.

[0014] A heating device that can be used for cooking steak as described above, a directional limiting slot hole is provided on the inner side wall of the heating and cooking cavity. The directional limiting slot hole extends from a position close to the second heating plate towards the direction close to the first heating plate, and the auxiliary sliding groove wheel of the supporting bracket is installed in the directional limiting slot hole.

[0015] The beneficial effects of the present invention are as follows: An elevating transmission mechanism for adjusting the separation distance between the heating plates is installed inside the device of the present invention. The elevating transmission mechanism drives the heating plate to rise or fall, realizing an expansion of the thickness adjustment range for cooking steak. Whether it is a thick steak or a thin steak, it can be adapted to be cooked within the lifting range. On this basis, by mechanically lifting the second heating plate, it can also replace manual clamping and pressing of the steak during frying. When frying, there is no need for manual cooking of the steak, and the double-sided compaction of the steak can also be achieved by relying on the top pressure of mechanical lifting, strengthening the full contact between the second heating plate and the steak, enhancing the heat receiving effect of the steak, and facilitating the use of users.

[0028] The following will describe in detail the implementation mode of the present invention with reference to the accompanying drawings.

[0029] Example 1: As Figures 1 to 5 shown, a heating device that can be used for cooking steak includes a fixed base 1, a movable flip cover 2, and a lifting transmission mechanism. The movable flip cover 2 is hinged and covers the fixed base 1 to form a heating and cooking cavity 6. The lifting transmission mechanism is installed at the bottom of the heating and cooking cavity 6. A first heating plate 7 is installed at the top of the heating and cooking cavity 6, and a second heating plate 8 is installed at the top of the lifting transmission mechanism. The lifting transmission mechanism can drive the second heating plate 8 to approach or move away from the first heating plate 7.

[0030] Specifically, in this embodiment, taking the cooking of steak as an example, the chassis shell is the outer box shell of the heating device. The base part of the chassis shell is the fixed base 1, and the top cover part of the chassis shell is the movable flip cover 2. The movable flip cover 2 is hermetically covered on the fixed base 1 to form a heating and cooking cavity 6 for cooking. A lifting transmission mechanism for conveniently lifting the steak is installed in the heating and cooking cavity 6. In order to clamp both sides to make the steak fully cooked by heat, a first heating plate 7 and a second heating plate 8 are respectively arranged on the upper and lower sides of the steak. Heating elements are respectively installed on the first heating plate 7 and the second heating plate 8. Among them, the first heating plate 7 is located above the steak to be cooked, that is, on the side of the heating and cooking cavity 6 away from the lifting transmission mechanism, and the second heating plate 8 is located below the steak to be cooked, that is, on the top of the lifting transmission mechanism. The cooking surfaces of the first heating plate 7 and the second heating plate 8 are arranged opposite to each other. The heating and cooking area for cooking the steak is between the first heating plate 7 and the second heating plate 8.

[0031] During use, connect the heating device to the power socket, and the heating element starts to heat up the first heating plate 7 and the second heating plate 8. The user can flip open the movable flap 2 and put the ingredients on the front side of the second heating plate 8. When the lifting transmission mechanism drives the second heating plate 8 to lift the steak, the steak is lifted until it touches the first heating plate 7. Under the clamping of the two sides of the first heating plate 7 and the second heating plate 8, the steak is cooked at a high temperature. After cooking, the user can open the chassis shell to take out the cooked steak and enjoy it. Then, the lifting transmission mechanism drives the second heating plate 8 to lower and reset, or keeps the lifting posture to facilitate the user to clean the oil stains on the second heating plate 8. In order to prevent the oil stains from spilling outside the heating plate, the lifting transmission mechanism preferably rises or descends in the vertical direction, so that the height of the heating and cooking area forms a variable, adjustable and controllable spatial change in the vertical direction, realizing an expanded thickness adjustment range for cooking steaks. Whether it is a thick steak or a thin steak, it can be adapted to be cooked within the lifting range, and there is no need for manual cooking of the steak during frying, which is convenient for the user to use.

[0032] Specifically, in this embodiment, the lifting transmission mechanism is installed at a position close to the bottom of the heating and cooking cavity 6 of the fixed base 1, facilitating smooth lifting and lowering in the vertical direction during lifting.

[0033] Specifically, in some embodiments, in addition to the application of the above-mentioned steak ingredients, the heating device of the present application can also be applied to the cooking of other ingredients such as chicken chops, pork chops, and lamb chops, or to the cooking of other dishes such as mashed potatoes, vegetable plates, meat cubes, and meat sauces. Details are not elaborated here and are not limited.

[0034] Furthermore, as one of its preferred embodiments, as Figure 2 shown in a heating device that can be used to cook steaks, at each corner of the bottom of the fixed base 1, there are also base feet 14 for easy placement. At least three base feet 14 can support the placement of the fixed base 1 simultaneously. Preferably, four base feet 14 support the placement of the fixed base 1 simultaneously, improving the placement stability of the chassis shell. In addition, combined with the use of the external base feet 11, it can avoid the situation that the fixed base 1 overturns due to the excessive weight of the heating plate of the movable flap 2, which is convenient for the user to use.

[0035] Furthermore, as one of its preferred embodiments, in order to further facilitate the user to operate the heating device, as Figures 1 to 5 shown in a heating device that can be used to cook steaks, a control panel 15 for operating the device is installed at a position on the fixed base 1 far from the hinge with the movable flap 2. The control panel 15 adopts a touchable electronic display screen. The control panel 15 is electrically connected to the heating element 73 for heating and the lifting transmission mechanism.

[0036] Specifically, in this embodiment, the entire plane of the control panel 15 is designed with a structure of an electronic display screen. Since the user's hands may be stained with oil during actual cooking and it is not easy to clean the oil stains adhering to the physical buttons, it is preferably to use a touch sensing method behind the electronic display screen to replace the physical buttons. When cleaning, only the stains on the surface of the electronic display screen need to be wiped clean. The control panel 15 is electrically connected to the heating element 73 for heating and the lifting transmission mechanism. The user can intuitively control the heating temperature of the heating element 73 from the control panel 15 to control the doneness of the steak, and can also intuitively control the lifting of the lifting transmission mechanism from the control panel 15 to control the cooking quality of the steak.

[0037] Further, as one preferred embodiment, in order to further facilitate the user to operate the heating device, such as Figure 3 shown in a heating device that can be used to cook steak, the control panel 15 is equipped with a screwing handle 16 that is convenient for controlling temperature adjustment. The screwing handle 16 is connected to the adjustment unit of the control panel 15. The user can adjust the temperature rise and fall of the heating element 73 by turning the screwing handle 16.

[0038] Further, as one preferred embodiment, such as Figures 1 to 5 shown in a heating device that can be used to cook steak, the movable flip cover 2 is provided with a flip cover handle 22 for the user to hold and facilitate opening. The flip cover handle 22 is arranged at a position of the movable flip cover 2 far from the hinge with the fixed base 1. When in use, the user holds the flip cover handle 22 and turns it towards the hinge of the movable flip cover 2, then the ingredients can be put into or taken out of the heating and cooking cavity 6.

[0039] Further, as one preferred embodiment, such as Figures 1 to 4 shown in a heating device that can be used to cook steak, the movable flip cover 2 is fastened to the fixed base 1 through a snap-fastening buckle 13. The snap-fastening buckle 13 is a buckle limiting structure installed on the fixed base 1 for buckling and locking the movable flip cover 2. After the ingredients are put in, the movable flip cover 2 is closed on the fixed base 1 and locked by the snap-fastening buckle 13 to prevent the movable flip cover 2 from opening during cooking and causing the ingredients to fall out. In addition, when the snap-fastening buckle 13 is used in combination with the flip cover handle 22, it can also facilitate the user to move the chassis shell randomly outdoors without worrying about the movable flip cover 2 suddenly opening during the movement, resulting in the separation of the fixed base 1 or uneven force and increasing the user's hand force, which is convenient for the user to use.

[0040] Further, as one preferred embodiment, such as Figures 5 to 6A heating device that can be used for cooking steak is shown. The first heating plate 7 is hung on the inner cavity side hole 61 of the movable flap 2 by the back of the plate buckle 71. An elastic member 91 for reducing impact and resetting is installed between the first heating plate 7 and the movable flap 2. After the first heating plate 7 is pressed to contact the microswitch 21 of the movable flap 2, the microswitch 21 triggers the lifting transmission mechanism to drive the second heating plate 8 to descend.

[0041] Specifically, in this embodiment, the back of the plate buckle 71 is a limit buckle structure provided on the back of the first heating plate 7 for restricting the installation position of the first heating plate 7 on the inner side of the movable flap 2. The inner side of the movable flap 2 is provided with an inner cavity side hole 61 for installing the first heating plate 7. The inner cavity side hole 61 has a certain space in height for the back of the plate buckle 71 to move up and down. A microswitch 21 for the first heating plate 7 to be pressed against is installed on one side of the movable flap 2 close to the first heating plate 7. An elastic member 91 for reducing impact is also installed between the first heating plate 7 and the movable flap 2. The elastic member 91 preferably adopts a spring structure.

[0042] During use, when the lifting transmission mechanism drives the second heating plate 8 to lift the steak and raises the steak until it contacts the first heating plate 7, the first heating plate 7 is pressed and continues to push up and touches the microswitch 21. The microswitch 21 triggers the descent of the lifting transmission mechanism. After the lifting transmission mechanism drives the second heating plate 8 to descend, the steak separates from the first heating plate 7. The pressure on the first heating plate 7 is eliminated and it is elastically pressed down by the elastic member 91 so that the back of the plate buckle 71 falls back to the bottom of the inner cavity side hole 61. At this time, the first heating plate 7 has separated from the microswitch 21, that is, the microswitch 21 is not triggering the descent of the lifting transmission mechanism, and the lifting transmission mechanism rises again. The lifting reciprocates several times, so that the steak is repeatedly pressed several times, imitating the effect of repeatedly compacting the steak with a cooking spatula by hand in actual cooking, and further improving the cooking effect.

[0043] Embodiment 3: As Figure 5 、 Figure 6 A heating device that can be used for cooking steak is shown. A heat insulation cover 72 for heat preservation and insulation is installed on the back of the first heating plate 7, and / or a heat insulation cover 72 for heat preservation and insulation is installed on the back of the second heating plate 8; A heating element 73 for heating the cooking temperature is installed inside the heat insulation cover 72.

[0044] Specifically, in this embodiment, the heating element 73 is a heating unit for heating the steak. Preferably, a heating wire or a heating tube is used. The heat insulation cover 72 is installed on the back of the heating plate. The heating element 73 extends from the side of the heat insulation cover 72 close to the heating plate and is bent along the outer edge of the heating plate. After being powered on, the heating element 73 starts to heat up and transfers the heat to the heating plate. After the heating plate is heated, it heats the steak. The heat insulation cover 72 gathers the heat of the heating element 73 towards the heating plate, improving the heat concentration, enhancing the heating efficiency, reducing the heat dissipation, and also being able to reduce the impact of the heat on the external structure of the heat insulation cover 72.

[0045] Further, as one of its preferred embodiments, in order to improve the heat concentration, enhance the heating efficiency, and reduce the heat dissipation, as Figure 5 , Figure 6 shown, for a heating device that can be used to cook steak, a heat insulation cover 72 for heat preservation and insulation is installed on the side of the first heating plate 7 away from the heating and cooking area, and a heat insulation cover 72 for heat preservation and insulation is installed on the side of the second heating plate 8 away from the heating and cooking area. Heating elements 73 for heating and cooking temperature are installed on both the side of the first heating plate 7 away from the heating and cooking area and the side of the second heating plate 8 away from the heating and cooking area. The heating elements 73 are located inside the heat insulation cover 72. Specifically, in this embodiment, heat insulation covers 72 are installed on both the first heating plate 7 and the second heating plate 8, gathering the heat from two different heating plates respectively, further improving the heat concentration, enhancing the heating efficiency, reducing the heat dissipation, and also being able to reduce the impact of the heat on the external structure of the heat insulation cover 72.

[0046] Further, as one of its preferred embodiments, in order to improve the heat concentration, enhance the heating efficiency, and reduce the heat dissipation, as Figure 5 , Figure 6 shown, for a heating device that can be used to cook steak, a heat preservation and insulation member is installed inside the chassis shell, and the heat preservation and insulation member is located at the bottom of the heating and cooking cavity 6, strengthening the gathering of the heat of the heating element 73 towards the heating plate, improving the heat concentration, enhancing the heating efficiency, reducing the heat dissipation, and also being able to reduce the impact of the heat on the external structure of the heat insulation cover 72.

[0047] Further, as one of its preferred embodiments, in order to improve the heat concentration, enhance the heating efficiency, and reduce the heat dissipation, as Figure 5 , Figure 6 shown, for a heating device that can be used to cook steak, a heat preservation and insulation member is installed inside the chassis shell, and the heat preservation and insulation member is located inside the heat insulation cover 72, strengthening the gathering of the heat of the heating element 73 towards the heating plate, improving the heat concentration, enhancing the heating efficiency, reducing the heat dissipation, and also being able to reduce the impact of the heat on the external structure of the heat insulation cover 72.

[0048] Embodiment 4: AsFigure 2 , Figure 5 A heating device that can be used to cook steak as shown. To solve the problem that the fixed base 1 may tip over due to unilateral force after the movable flap 2 is opened, an external base support foot 11 for supporting the force on the flap is installed at the position of the fixed base 1 close to the hinge with the movable flap 2. The external base support foot 11 extends from the hinge of the movable flap 2 towards the bottom and has a foot stabilizing plane 12 at the bottom.

[0049] Specifically, in this embodiment, the external base support foot 11 is supported below the hinge position of the fixed base 1 and the movable flap 2 through the foot stabilizing plane 12. The external base support foot 11 preferably adopts a structure that is narrower at the top and wider at the bottom, so that after the movable flap 2 is opened, there is sufficient supporting force below the hinge position to avoid the situation that the fixed base 1 tips over due to the excessive weight of the heating plate of the movable flap 2, which is convenient for users to use.

[0050] Embodiment 5: As Figures 4 to 8 shown, a heating device that can be used to cook steak. The lifting transmission mechanism includes a fixing member 3 for restricting the installation position, a transmission component 4 installed on the fixing member 3, and a driver 5 for providing power. The driver 5 drives the transmission component 4 to drive the second heating plate 8 to approach or move away from the first heating plate 7 in the vertical direction.

[0051] Specifically, in this embodiment, the fixing member 3 is a positioning and mounting fitting for installation inside the fixed base 1, which can fix the installation positions of the transmission assembly 4 and the driver 5 on the body shell inside the fixed base 1. The fixing member 3 is preferably a sheet metal part formed by a bending process, which is convenient for design, manufacturing and installation. The driver 5 can use a motor capable of forward and reverse rotation as the power source. The motor can be connected to the transmission shaft 41 through a transfer shaft so that the transmission shaft 41 can rotate synchronously with the output end of the motor. Among them, the transmission assembly 4 includes a transmission shaft 41 for transmitting power, a transmission member 42 for driving the link member 43, and a link member 43 for driving the second heating plate 8. The link member 43 can be composed of several links and hinge components (such as shafts, nails, circlips, etc.). When the driver 5 drives the transmission shaft 41 to rotate, the transmission member 42 moves directionally along the central axis direction of the transmission shaft 41. The link member 43 converts the power of the transmission member 42 moving axially into the power moving in the vertical direction, so that the second heating plate 8 rises or falls, achieving the effect of adjusting the thickness range of the steak cooking. On this basis, the driver 5 drives the second heating plate 8 located below the steak to press the heated steak upward through the transmission assembly 4, cooperating with the fixed second heating plate 8 above the steak of the steak cooking device. By mechanically lifting the second heating plate 8, it can also replace the manual clamping and frying of the steak. During frying, there is no need for manual manual pressing of the steak. Relying on the top pressure of mechanical lifting can also achieve double-sided compaction of the steak, strengthening the full contact of the second heating plate 8 with the steak, enhancing the heating effect of the steak, making the upper and lower sides of the steak evenly heated, and the cooking effect is better, which is convenient for users to use.

[0052] Embodiment 6: As Figures 9 to 12 shown, a heating device that can be used for cooking steak, the fixing member 3 includes a first fixing bracket 31 and a second fixing bracket 32. Between the first fixing bracket 31 and the second fixing bracket 32, a first balance support rod 33 and a second balance support rod 34 are installed and arranged in parallel on the left and right sides of the transmission member 42 respectively. The first balance support rod 33 passes through the left directional hole 423 of the transmission member 42, and the second balance support rod 34 passes through the right directional hole 424 of the transmission member 42. The transmission member 42 moves directionally along the first balance support rod 33 and the second balance support rod 34.

[0053] Specifically, in this embodiment, the first fixing bracket 31 and the second fixing bracket 32 are preferably in an L-shaped sheet metal bending structure. The first fixing bracket 31 and the second fixing bracket 32 support the transmission shaft 41 from both axial sides of the transmission shaft 41 respectively, making the transmission more stable and avoiding easy damage due to unilateral force. In addition, the first balance rod 33 and the second balance rod 34 are preferably in a smooth shaft structure. The first balance rod 33 and the second balance rod 34 pass through the transmission member 42 from the first fixing bracket 31 to reach the second fixing bracket 32, forming a balanced force structure mainly supported by the first fixing bracket 31 and the second fixing bracket 32. The first balance rod 33 and the second balance rod 34 are respectively arranged in parallel on the left and right sides of the transmission member 42, so that the transmission member 42 will not rotate in the circumferential direction due to the influence of the transmission of the transmission shaft 41 when moving, further improving the stability of the transmission and being beneficial to the directional movement of the transmission member 42.

[0054] Embodiment 7: As Figures 9 to 12 shown, a heating device that can be used for cooking steak, the transmission assembly 4 includes a transmission shaft 41, a transmission member 42, a connecting rod member 43 and a supporting rod 44. The transmission member 42 is installed on the transmission shaft 41. One end of the connecting rod member 43 is hinged to the transmission member 42, and the other end of the connecting rod member 43 is hinged to a supporting bracket 45 installed at the bottom of the second heating plate 8 through the supporting rod 44. The transmission shaft 41 rotates and drives the transmission member 42 to move axially. The transmission member 42 drives the supporting bracket 45 to rise or fall through the connecting rod member 43 and the supporting rod 44.

[0055] Specifically, in this embodiment, the transmission member 42 is movably connected to the transmission shaft 41 by a threaded structure. The outer surface of the transmission shaft 41 is provided with an external thread. One of the two transmission members 42 uses a left-handed thread, and the other of the two transmission members 42 uses a right-handed thread. One transmission member 42 implements threaded transmission by matching the left-handed internal thread with the external thread of the transmission shaft 41, and the other transmission member 42 implements threaded transmission by matching the right-handed internal thread with the external thread of the transmission shaft 41.

[0056] When the second heating plate 8 rises, the driver 5 (i.e., the driving motor) rotates forward to drive the transmission shaft 41 to rotate forward. At this time, the two transmission members 42 move away from each other along the axial direction of the transmission shaft 41 respectively. The two transmission members 42 drive the connecting rod member 43 to lift the supporting bracket 45 through the supporting rod 44 from different directions. When the supporting bracket 45 rises, the second heating plate 8 rises.

[0057] When the second heating plate 8 descends, the driver 5 rotates reversely to drive the transmission shaft 41 to rotate reversely. At this time, the two transmission members 42 move closer to each other along the axial direction of the transmission shaft 41 respectively. The two transmission members 42 drive the connecting rod member 43 to drive the supporting bracket 45 to descend through the supporting rod 44. When the supporting bracket 45 descends, the second heating plate 8 descends, realizing the lifting effect of the second heating plate 8.

[0058] Further, as a preferred embodiment thereof, as Figure 11 , Figure 12 shown, a lifting transmission mechanism for cooking steak, the transmission member 42 includes a transmission hinge portion 425 for steering hinge, the axial ends of the transmission hinge portion 425 are respectively hinged to the link member 43, and the central axis of the transmission hinge portion 425 is inclined to the moving direction of the transmission member 42.

[0059] Specifically, in this embodiment, the transmission hinge portion 425 is an integrally formed fixed structure on the transmission member 42, the link member 43 is a straight handle link structure, the transmission hinge portion 425 uses a pin shaft to hinge the link member 43, and the central axis of the internal thread hole of the transmission hinge portion 425 is inclined to the moving direction of the transmission member 42, preferably perpendicular to the moving direction of the transmission member 42, which can convert the horizontal directional movement of the transmission member 42 into the lifting movement of the second heating plate 8 in the vertical direction through the link member 43.

[0060] Embodiment 8: As Figures 9 to 12 shown, a heating device for cooking steak, the transmission assembly 4 includes two transmission members 42 with opposite internal thread helix directions, the outer surface of the transmission shaft 41 is provided with an external thread adapted to the internal thread, and the transmission shaft 41 rotates to drive the two transmission members 42 to approach or move away from each other through screw transmission.

[0061] Specifically, in this embodiment, one transmission member 42 implements screw transmission by matching the left-handed internal thread with the external thread of the transmission shaft 41, and the other transmission member 42 implements screw transmission by matching the right-handed internal thread with the external thread of the transmission shaft 41. When the second heating plate 8 rises, the motor of the drive assembly rotates forward to drive the transmission shaft 41 to rotate forward. At this time, the two transmission members 42 move away from each other along the axial direction of the transmission shaft 41 respectively, and the two transmission members 42 drive the link assembly to push the second heating plate 8 to rise. When the second heating plate 8 descends, the motor of the drive assembly rotates reversely to drive the transmission shaft 41 to rotate reversely. At this time, the two transmission members 42 approach each other along the axial direction of the transmission shaft 41 respectively, and the two transmission members 42 drive the link assembly to drive the second heating plate 8 to descend, realizing the lifting effect of the second heating plate 8.

[0062] Specifically, as another alternative embodiment, the link members 43 are arranged in a reverse cross manner. When the second heating plate 8 needs to descend, the motor of the drive assembly rotates forward to drive the transmission shaft 41 to rotate forward. At this time, the two transmission members 42 move away from each other along the axial direction of the transmission shaft 41 respectively, and the two transmission members 42 drive the link assembly to push the second heating plate 8 to descend; when the second heating plate 8 needs to rise, the motor of the drive assembly rotates reversely to drive the transmission shaft 41 to rotate reversely. At this time, the two transmission members 42 approach each other along the axial direction of the transmission shaft 41 respectively, and the two transmission members 42 drive the link assembly to drive the second heating plate 8 to rise, which can also realize the lifting effect of the second heating plate 8.

[0063] Further, as one of its preferred embodiments, as Figures 9 to 12 shown, a lifting transmission mechanism that can be used for cooking steak, the transmission member 42 includes a first transmission member 421 and a second transmission member 422, the connecting rod member 43 includes a first connecting rod member 431 and a second connecting rod member 432, the supporting rod 44 includes a first supporting rod 441 and a second supporting rod 442, the transmission member 42 is located between the first supporting rod 441 and the second supporting rod 442, the first transmission member 421 moves towards the direction close to the first supporting rod 441 and pushes one side of the supporting bracket 45 to rise through the first connecting rod member 431, and the second transmission member 422 moves towards the direction close to the second supporting rod 442 and pushes the other side of the supporting bracket 45 to rise through the second connecting rod member 432.

[0064] Specifically, in this embodiment, two transmission members 42 are respectively used to move in opposite directions. Among them, the first transmission member 421 is provided with a left-handed internal thread, and the second transmission member 422 is provided with a right-handed internal thread. When the transmission shaft 41 rotates, the first transmission member 421 and the second transmission member 422 approach or move away from each other through screw transmission. The moving ranges of the first transmission member 421 and the second transmission member 422 are within the space between the first supporting rod 441 and the second supporting rod 442. Among them, as Figure 9 shown, one end of the first connecting rod member 431 is hinged to the first transmission member 421, the other end of the first connecting rod member 431 is hinged to the first supporting rod 441, one end of the second connecting rod member 432 is hinged to the second transmission member 422, and the other end of the second connecting rod member 432 is hinged to the second supporting rod 442. During use, the motor drives the transmission shaft 41 to rotate. The first transmission member 421 moves towards the direction close to the first supporting rod 441 and pushes one side of the supporting bracket 45 to rise through the first connecting rod member 431, and the second transmission member 422 moves towards the direction close to the second supporting rod 442 and pushes the other side of the supporting bracket 45 to rise through the second connecting rod member 432, realizing the stable lifting of the second heating plate 8 by pushing through the supporting bracket 45 through the separate movement of the first transmission member 421 and the second transmission member 422.

[0065] Further, as one of its preferred embodiments, as Figure 9 shown, a lifting transmission mechanism that can be used for cooking steak, the supporting bracket 45 includes a first supporting bracket 451 and a second supporting bracket 452 respectively located on both sides of the bottom of the second heating plate 8. The transmission assembly 4 and the connecting rod member 43 are respectively located between the first supporting bracket 451 and the second supporting bracket 452. The supporting rod 44 passes through the first supporting bracket 451, the connecting rod member 43, and the second supporting bracket 452 in sequence, so that the connecting rod member 43 can drive the first supporting bracket 451 and the second supporting bracket 452 to rise synchronously through the supporting rod 44.

[0066] Specifically, in this embodiment, two supporting brackets 45 for facilitating the maintenance of lifting balance force are respectively arranged on both sides of the bottom of the second heating plate 8. Among them, the first supporting bracket 451 and the second supporting bracket 452 can adopt a symmetrically arranged structure. The transmission assembly 4 and the connecting rod member 43 are respectively located in the space between the first supporting bracket 451 and the second supporting bracket 452, so that the distance between the first supporting bracket 451 and the second supporting bracket 452 is relatively far apart, which can better maintain the balance of the lifting force. More specifically, the supporting rod 44 sequentially passes through the first supporting bracket 451, the connecting rod member 43, and the second supporting bracket 452. When the connecting rod member 43 is pushed, the first supporting bracket 451 and the second supporting bracket 452 on both sides of the rod are simultaneously lifted through the supporting rod 44, or when the connecting rod member 43 is pulled down, the first supporting bracket 451 and the second supporting bracket 452 on both sides of the rod are simultaneously lowered through the supporting rod 44, realizing the further strengthening of the lifting balance of the second heating plate 8 by respectively arranging the supporting brackets 45 on both sides.

[0067] Embodiment 9: As Figure 10 shown in a heating device that can be used for cooking steak, the end of the connecting rod member 43 far from the transmission member 42 is higher than the end close to the transmission member 42. When the distance between the two transmission members 42 is the minimum value within the stroke range, a connecting rod horizontal angle a is formed between the connecting rod member 43 and the horizontal plane where the central axis of the transmission shaft 41 is located, and the angle of the connecting rod horizontal angle a is greater than 0.5 degrees.

[0068] Specifically, in this embodiment, in order to prevent the connecting rod member 43 from having a dead point or getting stuck during the connecting rod movement, when the second heating plate 8 descends to the lowest position, the end of the connecting rod member 43 far from the transmission member 42 is higher than the end close to the transmission member 42. The end of the connecting rod member 43 close to the transmission member 42 is the low point, and the end of the connecting rod member 43 far from the transmission member 42 is the high point. The connecting rod member 43 still maintains a small-angle inclination with respect to the horizontal plane where the central axis of the transmission shaft 41 is located, so that the situation of being completely parallel to the horizontal plane will not occur. Preferably, when the distance between the two transmission members 42 is at the minimum value within the stroke range, a connecting rod horizontal angle a greater than 0.5 degrees is adopted between the connecting rod member 43 and the horizontal plane, so that the connecting rod member 43 always maintains an inclined posture with respect to the horizontal plane and can always meet the pushing of the transmission member 42.

[0069] Embodiment 10: As Figure 8 shown in a heating device that can be used for cooking steak, a directional limiting slot hole 62 is opened on the inner side wall of the cavity of the heating and cooking cavity 6. The directional limiting slot hole 62 extends from a position close to the second heating plate 8 towards the direction close to the first heating plate 7, and the auxiliary sliding groove wheel 453 of the supporting bracket 45 is installed in the directional limiting slot hole 62.

[0070] Specifically, in this embodiment, the directional limiting slot hole 62 is used to limit the lifting and moving direction of the support bracket 45. The directional limiting slot hole 62 can be symmetrically arranged on the inner side walls of the cavity on different sides of the heating cooking cavity 6 to improve the stability of both sides of the second heating plate 8 during lifting and moving. The support bracket 45 is installed with a sliding groove wheel 453 for adaptively installing in the directional limiting slot hole 62. The support bracket 45 can smoothly lift and slide up and down along the edge of the directional limiting slot hole 62 through the sliding groove wheel 453. The sliding groove wheel 453 plays a role in reducing the friction generated between it and the directional limiting slot hole 62 and reducing the friction loss.

[0071] Further, as one of its preferred embodiments, as Figure 8 shown, in a heating device that can be used for cooking steak, a tension spring 92 for reducing the lifting force burden of the lifting transmission mechanism is also installed inside the chassis shell. One end of the tension spring 92 is hooked on the sliding groove wheel 453 of the support bracket 45 and is in a lower position, and the other end of the tension spring 92 is hooked on the inner side wall of the heating cooking cavity 6 and is in a higher position. When the second heating plate 8 rises, the tension spring 92 generates an upward pulling force on the sliding groove wheel 453 to reduce the load of the lifting transmission mechanism when rising. When the second heating plate 8 descends, the tension spring 92 generates an upward pulling force on the sliding groove wheel 453 to improve the elastic buffer for the descent of the lifting transmission mechanism.

[0072] As Figures 1 to 12 shown, the specific implementation manner of the present invention is as follows: During use, the heating device is connected to a power socket, and the heating element 73 starts to heat up the first heating plate 7 and the second heating plate 8. The user can flip open the movable flap 2 and put the ingredients on the front side of the second heating plate 8. After starting cooking, the driver 5 drives the transmission shaft 41 to rotate. The first transmission member 421 moves towards the direction close to the first support rod 441 and pushes one side of the support bracket 45 to rise through the first link member 431. At the same time, the second transmission member 422 moves towards the direction close to the second support rod 442 and pushes the other side of the support bracket 45 to rise through the second link member 432, lifting the steak up to contact the first heating plate 7.

[0073] At this time, the first heating plate 7 is pressed and continues to push up and touches the microswitch 21. The microswitch 21 triggers the descent of the lifting transmission mechanism. When the lifting transmission mechanism drives the second heating plate 8 to descend, the steak separates from the first heating plate 7. The pressure on the first heating plate 7 is eliminated and it is elastically pressed down by the elastic member 91 so that the back of the plate 71 falls back to the bottom of the inner cavity side hole 61. At this time, the first heating plate 7 has separated from the microswitch 21, that is, the microswitch 21 is in a state of not triggering the descent of the lifting transmission mechanism, and the lifting transmission mechanism rises again. The lifting reciprocates several times, so that the steak is repeatedly pressed several times, imitating the effect of repeatedly compacting the steak with a cooking spatula by hand in actual cooking, and further improving the cooking effect.

[0074] Under the clamping of the two sides of the first heating plate 7 and the second heating plate 8, the steak is cooked at a high temperature. After cooking, the user can flip open the movable flap 2 to take out the food ingredients, and then the lifting transmission mechanism drives the second heating plate 8 to descend and reset, or maintains a lifting posture to facilitate the user to clean the oil stains on the second heating plate 8. In order to prevent the oil stains from spilling outside the heating plate, the lifting transmission mechanism preferably rises or descends in the vertical direction. The driver 5 drives the transmission shaft 41 to rotate, the first transmission member 421 moves towards the direction close to the second transmission member 422 and drives one side of the support bracket 45 to descend through the first connecting rod member 431. At the same time, the second transmission member 422 moves towards the direction close to the first transmission member 421 and drives the other side of the support bracket 45 to descend through the second connecting rod member 432, so as to lower the second heating plate 8 to the middle or bottom of the heating and cooking cavity 6.

[0075] The above only further illustrates the technical content of the present invention with examples to make it easier for readers to understand, but it does not mean that the implementation mode of the present invention is limited to this. Any technical extension or re-creation made according to the present invention is protected by the present invention. The protection scope of the present invention is subject to the claims.
