Description

Technical Field

[0001] The present application relates to the field of small household appliances, and in particular to a frying and grilling machine. Background Art

[0002] In daily life, grilling machines are usually used to cook and make flatbreads, and the food is heated by the heating tubes in the first grill assembly and / or the second grill assembly. During the cooking process, the food will puff up as the temperature rises, so that the height of the food gradually increases. If the cooking cavity of the grilling machine is too small, the puffing of the food will be blocked, and the food will not have a fluffy and crispy taste; if the cooking cavity is too high, the size of the grilling machine will increase, making it difficult to carry or store.

[0003] In order to adjust the height of the cooking cavity, in the prior art, such as US Pat. No. 05927539, a guide member that can slide up and down is set at the hinge device to adjust the height of the upper cover. However, the upper cover is too heavy to lift the guide member; or the guide member has high requirements for manufacturing, and the manufacturing cost of the grill is high. There is also a Chinese utility model patent CN202220196511.5, in which the guide member and the spring are set as an integrated structure so that the upper cover rises with the increase in the height of the food during the expansion of the food, so that the food has a fluffy and crispy taste. However, when the guide member and the spring are set as an integrated structure, during the process of fully opening the cover, when the opening angle between the upper cover and the lower cover is greater than 90°, the spring will provide the upper cover with an elastic force opposite to the gravity direction of the upper cover, so that the upper cover cannot be stably fixed relative to the lower cover, and even the upper cover will automatically close due to the spring elastic force, affecting the user experience. In the prior art, such as Chinese utility model patents CN210871148U and CN211609337U, a lifting device is provided at a position on the lower body opposite to the hinge device. Because the force arm between the lifting device and the hinge device is relatively long, the front cover of the upper cover will shake during the rising process of the upper cover, affecting the user experience. For example, Chinese utility model patent CN218606229U sets a support block on the lower grill assembly, and by rotating the support block, different sides abut against the upper / lower grill assembly, thereby changing the height of the cooking cavity.

[0004] However, in the prior art, no matter the lifting device is adjusting the state of the cooking cavity or not adjusting the state of the cooking cavity, the lifting device is in contact with the upper baking tray assembly or the lower baking tray assembly, so that the upper / lower baking tray assembly will exert a continuous and uninterrupted force on the lifting device, thereby causing the lifting device to reach its own fatigue strength and then break. Utility Model Content

[0005] In order to solve the above technical problems, the present application discloses a frying and grilling machine. When the height of the cooking cavity is not adjusted, the lifting device does not contact the baking tray assembly. When the height of the cooking cavity is adjusted, the lifting device contacts the baking tray assembly, thereby reducing the force of the upper / lower baking tray assembly on the lifting device.

[0006] The present application discloses a grilling machine, comprising a first grilling pan assembly and a second grilling pan assembly, wherein the first grilling pan assembly and the second grilling pan assembly enclose a cooking cavity, and a lifting device for adjusting the height of the cooking cavity is provided on the grilling machine, wherein the lifting device further comprises:

[0007] A connecting piece, arranged on the first baking tray assembly;

[0008] A rotating member is rotatably arranged on the connecting member via a rotating shaft, and the rotating member has a supporting position located between the first baking tray assembly and the second baking tray assembly, and an avoidance position located outside the first baking tray assembly and the second baking tray assembly. The rotating member rotates on the first baking tray assembly to achieve switching between the supporting position and the avoidance position, thereby changing the height of the cooking cavity.

[0009] Several optional methods are also provided below, but they are not intended to be additional limitations on the above-mentioned overall solution, but are merely further supplements or preferences. Under the premise that there are no technical or logical contradictions, each optional method can be combined with the above-mentioned overall solution separately, and multiple optional methods can also be combined.

[0010] Optionally, the first grilling tray assembly comprises a platform extending radially outward from the grilling machine, the connecting member is arranged on one side of the platform, and the rotating member rotates to the other side of the platform and is located at the supporting position.

[0011] Optionally, the first baking tray assembly includes a first shell and a first baking tray disposed in the first shell, the first baking tray has a side edge, an upper edge of the side edge extends outward to form a flange, and the platform is the flange.

[0012] Optionally, when the rotating member rotates to a supporting position, the rotating member abuts against a surface of the platform; when the rotating member rotates to a avoiding position, the rotating member is located outside the platform.

[0013] Optionally, the rotating shaft extends in the longitudinal direction of the grilling machine, and the rotating member flips around the rotating shaft.

[0014] Optionally, the rotating shaft extends in a transverse direction of the grilling machine, and the rotating member rotates horizontally around the rotating shaft.

[0015] Optionally, the connecting member includes a base, and two fixing plates extending longitudinally toward the second baking tray assembly are arranged on both sides of the base; the rotating shaft passes through a first axial hole on the rotating member and is fixedly connected to a second axial hole on each fixing plate.

[0016] Optionally, the bottom surface of the platform is connected to the mounting position of the connecting member, and the connecting arm on the connecting member is connected to the mounting position via a fastener.

[0017] Optionally, the connecting arm is bent to avoid the installation position and the platform.

[0018] Optionally, the connecting member extends laterally in a direction away from the first baking tray assembly to form a gripping portion.

[0019] The grilling machine of the present application can space the first grilling tray assembly from the second grilling tray assembly by radial rotation of the rotating member, thereby changing the height of the cooking cavity. In this way, the upper / lower grilling tray assembly will exert a force on the lifting device only when the rotating member spaces the first grilling tray assembly from the second grilling tray assembly, thereby reducing the force exerted by the upper / lower grilling tray assembly on the lifting device.

[0051] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0052] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be a central component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be a central component at the same time.

[0053] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0054] The grilling machine 100 places food on the first grilling pan assembly 200. When the grilling machine 100 is powered on, the heating tube works to generate heat, and the heat generated by the heating tube is transferred to the food, thereby heating the food. In the process of heating food, in order to create a high temperature and high heat environment for the food, the first grilling pan assembly 200 and the second grilling pan assembly 300 are usually covered together to form a sealed cooking cavity 400 to heat the food placed therein, so that the cooking time of the food can be accelerated. When making pancake-like food, because pancake-like food contains ingredients such as yeast, during the cooking process, the pancake will gradually become fluffy and the height will gradually increase. At this time, if the height of the cooking cavity 400 is low, the pancake placed on the first grilling pan 201 will contact the second grilling pan assembly because of the fluffyness, so that the second grilling pan assembly 300 will hinder the fluffy height of the food, making the food hard and dry.

[0055] In order to change the height of the cooking cavity 400, in the prior art, a retractable movable part is provided on the first baking tray assembly 200. During the cooking process, if the height of the food is relatively high, the movable part is adjusted to push up the second baking tray assembly 300, so that the first baking tray assembly 200 and the second baking tray assembly 300 are separated, and the height of the cooking cavity 400 is adjusted. However, during the lifting process, most of the weight of the second baking tray assembly 300 will fall on the movable part, which will cause the movable part to bear a large weight. The movable part is arranged on the opposite side of the hinge device of the first baking tray assembly 200 and the second baking tray assembly 300, so that during the process of changing the height of the cooking cavity 400, the movable part will always press against the second baking tray assembly 300, and the movable part will extend from the through hole on the first baking tray assembly 200 to abut against the second baking tray assembly 300. The user turns the knob to provide the movable part with a force to extend upward through the through hole, and the movable part abuts against the second baking tray assembly 300 after passing through the through hole. The force given to the movable part by the knob to lift it drives the second baking tray assembly 300 to rise, thereby adjusting the height of the cooking cavity 400. In this way, most of the gravity of the second baking tray assembly 300 is pressed on the movable part, and in order not to hinder the user's observation of the food during the cooking process or to facilitate the turning of the food, the movable part is usually made relatively small, which will result in that the movable part can withstand less pressure and cannot support the rise and fall of the second baking tray assembly 300 for a long time.

[0056] Or in other prior arts, in order to adjust the height of the cooking cavity 400, a support block is provided on the side of the grilling machine 100, and the cooking cavity 400 is adjusted to different heights by rotating the support block. The support block is arranged in a long strip shape, and a groove 503 is arranged on the second baking tray assembly 300. The support block is arranged at the groove 503. The support block also includes a first surface, a second surface, a third surface and a fourth surface arranged in sequence in a clockwise direction, wherein the first surface and the third surface are arranged opposite to each other. When the first baking tray assembly 200 and the second baking tray assembly 300 are abutted against each other, the first surface of the support block contacts the second baking tray assembly 300, and the third surface contacts the first baking tray 201. When the first baking tray assembly 200 and the second baking tray assembly 300 are abutted against each other, the support block is arranged on the second baking tray assembly 300, and the second surface and the fourth surface symmetrically arranged face the first baking tray assembly 200. When the height of the cooking cavity 400 needs to be adjusted, the user rotates the support block. In one embodiment, the user can rotate the support block in a clockwise direction so that the fourth surface contacts the second baking tray assembly 300, the second surface contacts the first baking tray assembly 200, and the first surface contacts the side wall of the groove 503, so as to change the height of the cooking cavity 400. In this method of adjusting the height of the cooking cavity 400 by rotating the support block itself, at least one surface of the support block is in contact with the second baking tray assembly 300, whether when the first baking tray assembly 200 and the second baking tray assembly 300 are in contact or when the height of the cooking cavity 400 needs to be adjusted. In particular, in the process of adjusting the height of the cooking cavity 400, after the support block is rotated, the support block not only needs to lift the second baking tray assembly 300 by changing its own height, but also the weight of the second baking tray assembly 300 will gradually press against the support block during the rotation of the support block, and the support block changes from contacting the second baking tray assembly 300 with the longer side to contacting the second baking tray assembly 300 with the shorter side, so that the support block gradually bears more weight of the second baking tray assembly 300. In this way, the second baking tray assembly 300 will continuously and repeatedly exert force on the support block, so that the support block quickly reaches its own fatigue strength and then breaks.

[0057] like Figure 1 , Figure 2 , Figure 8 , Fig.17 , Fig.18 and Fig.19As shown, in order to reduce the force of the baking tray assembly on the lifting device 500 during the process of adjusting the height of the cooking cavity 400, the time for the lifting device 500 to reach fatigue strength can be slowed down, thereby extending the service life of the lifting device 500. The grilling machine 100 of the present application comprises a first grilling pan assembly 200 and a second grilling pan assembly 300, wherein the first grilling pan assembly 200 and the second grilling pan assembly 300 are combined to form a cooking cavity 400, and a lifting device 500 for adjusting the height of the cooking cavity 400 is provided on the grilling machine 100, and the lifting device 500 further comprises: a connecting member 501, which is provided on the first grilling pan assembly 200; a rotating member 502, which is rotatably provided on the connecting member 501 via a rotating shaft 527, and the rotating member 502 has a supporting position located between the first grilling pan assembly 200 and the second grilling pan assembly 300, and an evacuation position located outside the first grilling pan assembly 200 and the second grilling pan assembly 300, and the rotating member 502 radially rotates on the first grilling pan assembly 200 to realize switching between the supporting position and the evacuation position, thereby changing the height of the cooking cavity 400.

[0058] In this embodiment, the rotating member 502 is fixed to the connecting member 501 via the rotating shaft 527, and the rotating member 502 can rotate around the rotating shaft 527. When the rotating member 502 moves from the avoidance position to the support position, the rotating member 502 can be rotated in one direction with the rotating shaft 527 as the axis, and then the rotating member 502 enters the support position; when the rotating member 502 needs to move from the support position to the avoidance position, the rotating member 502 can be rotated in the opposite direction with the rotating shaft 527 as the axis, and then the rotating member 502 enters the avoidance position.

[0059] In this embodiment, the first grill assembly 200 and the second grill assembly 300 enclose a cooking cavity 400, and the lifting device 500 is used to adjust the height of the cooking cavity 400. The grilling machine 100 is usually placed on a table, the first grill assembly 200 is placed parallel to the table, and the second grill assembly 300 is buckled and arranged on the first grill assembly 200. Food is placed on the first grill assembly 200 and heated by the heating tube, and the second grill assembly 300 can be flipped and covered on the first grill assembly 200, which can not only heat the upper surface of the food, but also prevent the loss of heat in the cooking cavity 400. Generally, the baking tray assembly that is placed flat on the table and on which food is placed is called the lower baking tray assembly; the baking tray assembly that is buckled on the lower baking tray assembly and can be flipped and covered is called the upper baking tray assembly; the first baking tray assembly 200 in the present application is the lower baking tray assembly, and the second baking tray assembly 300 is the upper baking tray assembly. Of course, because the lifting device 500 in the present application is set between the upper baking tray assembly and the lower baking tray assembly, it is easy to convert, so the first baking tray assembly 200 in the present application can also be the upper baking tray assembly, and the second baking tray assembly 300 can also be the lower baking tray assembly.

[0060] In the present application, the grilling machine can work in the avoidance position, at which time the height of the cooking cavity is the initial height; the grilling machine can also work in the support position, at which time the height of the cooking cavity is the initial height plus the lifting height of the lifting device 500. The grilling machine can also work during the switching between the avoidance position and the support position. In actual work, when the user can predict that the height of the food after cooking is lower than the height of the cooking cavity, the moving part 502 is always in the avoidance position, and the height of the cooking cavity is always the initial height; when the height of the uncooked food is higher than the height of the cooking cavity, the moving part 502 is always in the support position, and the height of the cooking cavity is always the lifting height; when the initial height of the cooked food is lower than the height of the cooking cavity, after being heated by the grilling machine 100, the food expands, and the height of the expanded food is higher than the height of the cooking cavity. Therefore, before the grilling machine works, the moving part 502 is in the avoidance position. During the operation of the grilling machine, the moving part 502 can be moved from the avoidance position to the support position so that the height of the cooking cavity reaches the lifting height to meet the height of the expanded food.

[0061] The moving member 502 can move on the first baking tray assembly 200. When the first baking tray assembly 200 and the second baking tray assembly 300 are in contact with each other, the moving member 502 moves in a direction away from the cooking cavity 400, and the moving member 502 does not contact with the first baking tray assembly 200 or the second baking tray assembly 300. When the height of the cooking cavity 400 needs to be adjusted, the second baking tray assembly 300 is first opened, and then the moving member 502 is rotated in a direction close to the cooking cavity 400, so that the moving member 502 contacts with the first baking tray assembly 200, and then the second baking tray assembly 300 is covered, so that the moving member 502 contacts with the second baking tray assembly 300. At this time, the moving member 502 contacts with the first baking tray assembly 200 and the second baking tray assembly 300, and the moving member 502 can support the second baking tray assembly 300, so that the first baking tray assembly 200 and the second baking tray assembly 300 are spaced apart, thereby changing the height of the cooking cavity 400. At this time, the height of the cooking cavity 400 becomes higher, which can provide sufficient space for the expansion of food, and the movable member 502 is first extended into the middle of the first baking tray assembly 200 and the second baking tray assembly 300 when it is opened between the first baking tray assembly 200 and the second baking tray assembly 300, and then the second baking tray assembly 300 is buckled on the first baking tray assembly 200. At this time, because the movable member 502 is provided between the first baking tray assembly 200 and the second baking tray assembly 300, the first baking tray assembly 200 and the second baking tray assembly 300 are not completely closed, but the second baking tray assembly 300 is supported by the movable member 502, so that the first baking tray assembly 200 and the second baking tray assembly 300 are spaced apart. In this way, the movable member 502 is only in contact with the first baking tray assembly 200 and the second baking tray assembly 300 when adjusting the height of the cooking cavity 400, and when the height of the cooking cavity 400 is at the original height, the movable member 502 is not in contact with the first baking tray assembly 200 and the second baking tray assembly 300, thereby reducing the time for the second baking tray assembly 300 to exert a force on the movable member 502 and increasing the time for the movable member 502 to reach its own fatigue strength; at the same time, the movable member 502 lifts the first baking tray assembly 200 and the second baking tray assembly 300 by supporting, while most of the prior art lifts the second baking tray assembly 300 by the movable member 502, and during the lifting process, the second baking tray assembly 300 will apply greater pressure to the movable member 502, so that the movable member 502 reaches its own fatigue strength faster.

[0062] In order to enable the moving member 502 to move smoothly on the first baking tray assembly 200, the moving member 502 is provided with a connecting member 501 and a moving member 502. The radial movement of the moving member 502 on the connecting member 501 includes: in one embodiment, the connecting member 501 and the moving member 502 are integrated, and during the movement of the moving member 502, the connecting member 501 and the moving member 502 move together along the radial direction of the first baking tray assembly 200; in one embodiment, the connecting member 501 and the moving member 502 are separately arranged, and during the movement of the moving member 502, the connecting member 501 is fixed on the first baking tray assembly 200 and does not move, and only the moving member 502 makes relative movement on the connecting member 501, and the support of the second baking tray assembly 300 is achieved only by the radial rotation of the moving member 502.

[0063] The portion of the rotating member 502 for spacing the first baking tray assembly 200 and the second baking tray assembly 300 that contacts the second baking tray assembly 300 is in the shape of a long strip. In the prior art, when the lifting device 500 is rotated to lift up the second baking tray assembly 300, in order to enable the user to lift up the second baking tray assembly 300 with less force, the area of ​​the portion of the lifting device 500 that contacts the second baking tray assembly 300 is small. Although this allows the user to lift the lifting device 500 and the second baking tray assembly 300 together with less force, since the contact area between the lifting device 500 and the second baking tray assembly 300 is small, most of the gravity of the second baking tray assembly 300 is concentrated in the small area, so that the second baking tray assembly 300 exerts a large force on the lifting device 500 per unit area, which easily causes the lifting device 500 to reach its own fatigue strength. In the present embodiment, the portion of the rotating member 502 that contacts the second baking tray assembly 300 is configured to be a strip with a larger contact area. In this way, when the weight of the second baking tray assembly 300 is pressed on the strip with a larger area, the strip will disperse the force of the second baking tray assembly 300 on the lifting device 500, thereby making the force of the second baking tray assembly 300 on the lifting device 500 smaller per unit area. The gravity of the second baking tray assembly 300 is dispersed on the strip-shaped lifting structure, and it is not easy for the lifting device 500 to reach its own fatigue strength.

[0064] When the second grilling pan assembly 300 is pressed on the lifting device 500, if the lifting device 500 is relied on alone to support the second grilling pan assembly 300, the lifting device 500 may be deformed or even damaged by the second grilling pan assembly 300. In order to provide more support to the lifting device 500, so that the lifting device 500 can better support the second grilling pan assembly 300, the first grilling pan assembly 200 includes a first grilling pan 201, and a connecting member 501 and a rotating member 502 clamp the first grilling pan 201. The first grilling pan assembly 200 includes a platform 202 extending outwardly along the radial direction of the grilling machine 100, the connecting member 501 is arranged on one side of the platform 202, and the rotating member 502 rotates to the other side of the platform 202 and is located at a supporting position. In the prior art, the first baking tray assembly 200 usually only plays a role of fixing and connecting the lifting device 500, and has a relatively small supporting effect on the lifting device 500. For example, the movable part that can be extended and retracted in the first baking tray assembly 200 mentioned above, the first baking tray assembly 200 only plays a role of fixing the movable part, and the force supporting the second baking tray assembly 300 is all borne by the movable part. In this embodiment, by extending the first baking tray 201 into the lifting device 500, when supporting the second baking tray assembly 300, the first baking tray 201 can provide a certain supporting force for the lifting device 500 to support the second baking tray assembly 300 together. The first baking tray 201 is clamped between the connecting member 501 and the rotating member 502 of the lifting device 500. When the second baking tray assembly 300 is placed on the upper end of the rotating member 502, the gravity of the second baking tray assembly 300 will pass through the rotating member 502, the first baking tray 201 and the connecting member 501 in sequence. In this way, the gravity of the second baking tray assembly 300 is shared step by step after passing through the three components, and the gravity of the second baking tray assembly 300 borne by each component will be greatly reduced. The rotating member 502 that bears the most gravity will not be suspended on the first baking tray assembly 200 because the first baking tray 201 is supported below the rotating member 502. Instead, when the second baking tray assembly 300 presses down the rotating member 502, the first baking tray 201 will support the rotating member 502. Because the first baking tray 201 needs to hold food and be heated at high temperature through the heating tube, the strength of the first baking tray 201 will be much greater than the strength of the lifting device 500. The weight of the second baking tray assembly 300 is much greater than the weight of the rotating member 502. When the second baking tray assembly 300 applies pressure to the rotating member 502, the rotating member 502 is deformed. The deformed rotating member 502 is blocked by the first baking tray 201, so the deformation of the rotating member 502 is reduced, thereby helping the rotating member 502 to complete the support of the second baking tray assembly 300.Without the support of the first baking tray 201 , when the rotating member 502 is subjected to the downward pressure of the second baking tray assembly 300 whose gravity is much greater than its own gravity, it will be deformed or broken because it cannot withstand the pressure of the second baking tray assembly 300 .

[0065] like Fig.11 As shown, the top surface 523 of the platform 202 abuts against the cross-blocking surface 522 of the rotating member 502, and the rotating member 502 is supported by the top surface 523. In this way, the pressure of the second baking tray assembly 300 is transmitted to the top surface 523 of the platform 202 through the rotating member 502, so that the pressure of the second baking tray assembly 300 can be withstood.

[0066] like Figure 3 As shown, because the first baking tray 201 is detachable, when the grilling machine 100 is in operation, the first baking tray 201 needs to be detached to be cleaned, or the food placed in the first baking tray 201 needs to be taken out. At this time, because the temperature of the first baking tray 201 will rise due to the heating of the heating tube, if the user directly touches the heated area of ​​the first baking tray 201, the user will be scalded. In order to prevent the user from being scalded when removing the first baking tray 201, the first baking tray assembly 200 includes a first shell and the first baking tray 201 placed in the first shell. The first baking tray 201 has a side, and the upper edge of the side extends outward to form a flange 203, and the platform 202 is the flange 203. Because the flange 203 is far away from the heating tube and the flange 203 is formed by the upper edge of the side extending outward, the heat transferred from the heating tube to the flange 203 is relatively small. At the same time, because the lifting device 500 is provided on the flange 203, the flange 203 can be reused as a handle, and the user can move the first baking tray 201 by holding the flange 203. In the process of changing the height of the cooking cavity 400, the rotating member 502 rotates to the supporting position, and the rotating member 502 abuts against the surface of the platform 202; the rotating member 502 rotates to the avoiding position, and the rotating member 502 is located outside the platform 202.

[0067] The connecting arm 525 is provided with a heat dissipation hole 526. In this way, the heat transferred from the heating tube to the connecting member 501 can be dissipated to the external environment through the heat dissipation hole 526, which can reduce the increase in the temperature of the handle during the operation of the grilling machine.

[0068] like Figure 5 and Figure 6As shown, in order to enable the lifting device 500 to better fit and surround the first baking tray 201 and reduce the height of the gap after the first baking tray 201 extends into the lifting device 500, the rotating member includes a groove 503, and a first arm 504 is provided at the lower end of the groove 503, and the first arm 504 contacts the bottom side of the first baking tray 201; a second arm 505 is provided at the upper end of the groove 503, and the second arm 505 contacts the top side of the first baking tray 201 and supports the second baking tray assembly 300 through the second arm 505. If the gap between the first baking tray 201 and the lifting device 500 is large, the lifting device 500 cannot be firmly fixed on the first baking tray 201, and it is easy to shake. In serious cases, the lifting device 500 will fall off the first baking tray 201. In order to enable the first baking tray 201 to be firmly clamped in the middle of the lifting device 500, a groove 503 is provided on the lifting device 500, and the first baking tray 201 extends into the groove 503. The first arm 504 at the lower end of the groove 503 contacts the bottom side of the first baking tray 201, and the second arm 505 at the upper end of the groove 503 contacts the top side of the first baking tray 201. The first arm 504 in contact with the bottom side of the first baking tray 201 is the connecting member 501, which can be fixed on the first baking tray 201 or can slide on the first baking tray 201; the second arm 505 in contact with the top side of the first baking tray 201 is the rotating member 502, and when the height of the cooking cavity 400 needs to be adjusted, the second arm 505 contacts the top side of the first baking tray 201, thereby supporting the second baking tray assembly 300. The first baking tray 201 is clamped in the middle of the lifting device 500 by the first arm 504 and the second arm 505, so that the gap between the first baking tray 201 and the lifting device 500 can be reduced.

[0069] like Fig. 9As shown, in order to enable the lifting device 500 to slide more smoothly on the first baking tray assembly 200 and prevent the lifting device 500 from being stuck due to unsmooth sliding, the lifting device 500 includes a sliding channel 506 and a sliding rib 507, and the rotating member 502 rotates on the connecting member 501 through the cooperation of the sliding channel 506 and the sliding rib 507. The sliding channel 506 is provided on one of the connecting member 501 or the rotating member 502, and the sliding rib 507 that cooperates with the sliding channel 506 is provided on the other of the connecting member 501 or the rotating member 502. In the prior art, the lifting device 500 rotates by friction between the peripheral surface and the first baking tray assembly 200. However, the peripheral surface of the lifting device 500 has different heights. After a long time, pits of different depths will be worn out by the lifting device 500 on the first baking tray assembly 200, which will affect the rotation of the lifting device 500 on the first baking tray assembly 200. In order to make one surface of the lifting device 500 always serve as a sliding surface, a sliding channel 506 and a sliding rib 507 are provided, and the lifting device 500 rotates between the first baking tray 201 through the cooperation between the sliding channel 506 and the sliding rib 507.

[0070] In one embodiment, when the first arm 504 and the second arm 505 are integrated, the first arm 504 is configured as a long block structure, and the lifting device 500 can rotate along the long side direction of the long block structure, so as to adjust the position relationship between the lifting device 500 and the first baking tray 201. The second arm 505 is configured as a rectangular parallelepiped structure, and the shorter sides of the rectangular parallelepiped structure are arranged on both sides of the lifting device 500, so that the abutting surface of the rectangular parallelepiped structure against the second baking tray assembly 300 is a surface with a larger area, which can be used to disperse the force of the second baking tray assembly 300 on the lifting device 500.

[0071] like Figure 8 , Fig.12 and Fig.13As shown, in one embodiment, when the first arm 504 and the second arm 505 are separately arranged, the rotating member 502 includes a supporting surface 512, a first side surface 513 formed by longitudinally extending along both sides of the supporting surface 512, and the connecting member 501 has a second side surface 514 extending longitudinally, and the first side surface 513 is located on the outer side of the second side surface 514; the first side surface 513 is provided with a rib 515 extending inwardly, and the rib 515, the first side surface 513 and the supporting surface 512 form a strip channel 516, and the second side surface 514 is provided with a sliding rib 507, which is embedded in the strip channel 516, and the strip channel 516 and the sliding rib 507 cooperate to allow the rotating member 502 to rotate on the connecting member 501. In a preferred embodiment, one end of the first arm 504 is fixed to the first baking tray 201 by a fastener 511, and a sliding channel 506 is provided at the other end. The second arm 505 covers the outer surface of the sliding channel 506 and slides on the sliding channel 506. The first arm 504 is configured as a U-shaped structure, and both sides of the U-shaped structure cooperate with the first arm 504. The top wall of the U-shaped structure cooperates with the sliding channel 506 to realize the sliding of the rotating member 502 relative to the connecting member 501.

[0072] like Figure 4 , Fig.10 and Fig.11As shown, in order to prevent the rotating member 502 from extending too far into the cooking cavity 400 when rotating, or the rotating member 502 from separating from the lifting device 500 during the rotation process, a first limiting structure 517 is provided on the rotating member 502, and the first limiting structure 517 abuts against the platform 202 to limit the rotating member 502 from rotating inwardly, and the rotating member 502 is located in the supporting position; and / or, a second limiting structure 518 is provided on the connecting member 501, and the rotating member 502 abuts against the second limiting structure 518 to limit the rotating member 502 from rotating outwardly, and the rotating member 502 is located in the avoiding position. The first limiting structure 517 is a step 519, and when in the supporting position, the step 519 abuts against the flange 203, thereby limiting the shortest distance between the rotating member 502 and the first baking tray 201. The second limiting structure 518 is a protrusion 508, which limits the radial rotation distance of the rotating member 502. The protrusion 508 cooperates with the first baking tray 201 to limit the movement stroke of the rotating member 502. The protrusion 508 is used to limit the maximum distance of the rotating member 502 from the first baking tray 201. If the protrusion 508 is set closer to the first baking tray 201, the rotating member 502 will not be able to completely break away from the contact with the first baking tray 201, so that the protrusion 508 and the first baking tray 201 are always in abutment state, the first baking tray assembly 200 and the second baking tray assembly 300 cannot be abutted, and the first baking tray assembly 200 and the second baking tray assembly 300 are always in a spaced state; if the protrusion 508 is set farther, although the rotating member 502 and the second baking tray assembly 300 cannot be abutted, the longer stroke will also cause the sliding channel 506 to be longer, so that the grilling machine 100 occupies a larger space for transportation or storage, which is inconvenient for users to transport or store the grilling machine 100. Therefore, when the rotating member 502 abuts against the protrusion 508, the moving block does not abut against the first grilling plate 201, so that the protrusion 508 can limit the rotating member 502 and reduce the space occupied by the grilling machine 100.

[0073] like Fig.14 As shown, as a preferred embodiment, a step 519 is provided on the rotating member 502, and a vertical stop surface 521 of the step 519 abuts against the platform 202 to limit the inward rotation of the rotating member 502, and the rotating member 502 is located at a supporting position between the first baking tray assembly 200 and the second baking tray assembly 300. The vertical stop surface 521 abuts against the platform 202 in a surface contact manner, which can well limit the rotation distance of the rotating member 502 when rotating toward the supporting position.

[0074] like Figure 4As shown, in another embodiment, the rotating member 502 includes a groove 503, and the platform 202 extends into the groove 503; a convex channel 520 is provided on the connecting member 501, and a protrusion 508 is provided on the rotating member 502, and the protrusion 508 cooperates with the convex channel 520 to allow the rotating member 502 to rotate on the connecting member 501.

[0075] In the prior art, the movable part on the grilling machine 100 is arranged on the opposite side of the hinge of the first grilling pan assembly 200 and the second grilling pan assembly 300. In this way, when the second grilling pan assembly 300 is lifted by the movable part, the movable part will shake due to the long distance from the center of gravity of the second grilling pan assembly 300, which affects the lifting of the second grilling pan assembly 300 by the movable part. Therefore, the lifting device 500 is arranged on the side of the grilling machine 100. In this embodiment, by arranging the lifting device 500 on the side of the grilling machine 100, the center of gravity of the lifting device 500 to the second grilling pan assembly 300 can be reduced, so that the second grilling pan assembly 300 can be lifted more stably.

[0076] In one embodiment, the lifting device 500 can be provided as one, and the second grilling plate assembly 300 is supported by a single lifting device 500 provided on the side of the grilling machine 100. However, if the second grilling plate assembly 300 is supported by only a single lifting device 500, the part of the second grilling plate assembly 300 that contacts the lifting device 500 will be lifted, while the part of the second grilling plate assembly 300 that does not contact the lifting device 500 will still contact the first grilling plate assembly 200, and the second grilling plate assembly 300 cannot be fully lifted. Therefore, two lifting devices 500 are provided, and they are symmetrically arranged. In this way, when it is necessary to adjust the height of the cooking cavity 400, the two lifting devices 500 are simultaneously rotated along the radial direction of the grilling machine 100, and the two lifting devices 500 are used to jointly set the second grilling plate assembly 300 and the first grilling plate assembly 200 at an interval, so as to prevent the second grilling plate assembly 300 from being partially lifted and partially still contacting the first grilling plate assembly 200.

[0077] The rotating member 502 includes a supporting surface 512 abutting against the second baking tray assembly 300, and at least one step 509 is arranged on the supporting surface 512. The second baking tray assembly 300 abuts against the supporting surface 512 or the step 509 to adjust the height of the cooking cavity 400. When making food, the expansion heights of different foods will be different. If the height of the cooking cavity 400 is adjusted to be higher, the second baking tray assembly 300 cannot fit with the expanded food, thereby affecting the heating efficiency of the second baking tray assembly 300 on the food. Therefore, a plurality of steps 509 are arranged on the surface where the supporting part contacts the second baking tray assembly 300. In this way, the second baking tray assembly 300 can be placed on different steps 509, so that the heights of different cooking cavities 400 can be adjusted. When one step 509 is arranged, the step abuts against the second baking tray assembly 300, and the cooking cavity can only change one height; when multiple steps 509 are arranged, the second baking tray assembly 300 can only abut against one of the steps, and different steps correspond to different heights of the cooking cavity. In this case, the cooking cavity can change multiple heights.

[0078] After the lifting device 500 has supported the second grilling tray assembly 300, when the first grilling tray assembly 200 and the second grilling tray assembly 300 need to be adjusted from the mutually spaced state to the close state, the lifting device 500 needs to be slid from the close state to the first grilling tray 201 to the state separated from the first grilling tray 201. In order to provide a better hand feeling for the user during the sliding process, an elastic member 510 extending along the axial direction of the grilling machine 100 is provided on the platform 202, and an elastic force is provided to the rotating member 502 through the elastic member 510. The elastic member 510 is provided on the first grilling tray 201, and extends along the axial direction of the first grilling tray 201, with one end of the elastic member 510 abutting against the sliding part and the other end abutting against the supporting part.

[0079] like Figure 7 As shown, the rotating member 502 can be provided separately, or can be a part of the folding sheet 601 on the folding handle 600 . The smooth folding sheet 601 can provide a better sliding space for the lifting device 500 .

[0080] If there is a large gap between the platform 202 and the lifting device 500, when the second baking tray assembly 300 presses on the lifting device 500, the gap will cause the pressure of the second baking tray assembly 300 on the platform 202 and the lifting device 500 to be unbalanced, thereby causing the platform 202 and the lifting device 500 to break. In order to make the platform 202 and the lifting device 500 more compact, the bottom surface of the platform 202 is connected to the installation position 524 of the connecting member 501, and the connecting arm 525 on the connecting member 501 is connected to the installation position 524 through the fastener 511. In this way, the top and bottom surfaces of the platform 202 are utilized, so that the lifting device 500 can be set closely against the top and bottom surfaces of the platform 202.

[0081] like Fig. 20 , Fig.21 , Fig. 22 , Fig.23 and Fig.24 As shown, when the rotating member 502 is pushed from the avoidance position to the supporting position by sliding, if the sliding between the rotating member 502 and the connecting member 501 is not smooth enough, the rotating member 502 is likely to get stuck, thereby affecting the rotation of the rotating member 502. Therefore, in this embodiment, the rotating shaft extends along the longitudinal direction of the grilling machine, and the rotating member 502 is turned around the rotating shaft 527, so that the abutting surface 533 on the rotating member 502 that abuts against the connecting member 501 is turned to abut against the second grilling tray assembly 300. As a preferred solution, the rotating shaft 527 is arranged horizontally at this time. When the rotating member 502 is in the avoidance position, the abutment surface 533 abuts against the connecting member 501. When the rotating member 502 needs to be rotated from the avoidance position to the supporting position, the rotating member 502 is flipped 180 degrees in the positive direction along the rotating shaft 527. At this time, the abutment surface 533 faces the second baking tray assembly 300 and abuts against the second baking tray assembly 300, thereby adjusting the height of the cooking cavity; when the rotating member 502 needs to be rotated from the supporting position to the avoidance position, the rotating member 502 is flipped 180 degrees in the opposite direction along the rotating shaft 527, so that the abutment surface 533 abuts against the connecting member 501 again.

[0082] In one embodiment, the rotating shaft extends in the lateral direction of the grilling machine, the rotating member 502 rotates horizontally around the rotating shaft 527, and the abutting surface 533 on the rotating member 502 is arranged opposite to the connecting member 501. At this time, the rotating shaft 527 is arranged vertically, and the rotating member 502 rotates around the rotating shaft 527 substantially along the same plane. When the rotating member 502 is located at the avoidance position, the abutting surface 533 abuts against the connecting member 501. When the rotating member 502 needs to rotate from the avoidance position to the supporting position, the rotating member 502 rotates horizontally around the rotating shaft 527, and at this time, the abutting surface 533 faces the first grilling plate assembly 200, and the rotating member 502 supports the second grilling plate assembly 300.

[0083] The connecting member 501 includes a base 528 , on both sides of which are provided two fixing plates 529 extending longitudinally toward the second baking tray assembly 300 ; the rotating shaft 527 passes through a first shaft hole 530 on the rotating member 502 and is fixedly connected to a second shaft hole 531 on each fixing plate 529 .

[0084] In order to facilitate the user to rotate the first grill assembly 200 through the connecting member 501, the connecting member 501 extends laterally away from the first grill assembly 200 to form a gripping portion 532. The setting of the gripping portion 532 can facilitate the user to hold the connecting member 501, and the gripping portion 532 formed by the laterally extending gripping portion 532 can reduce the transfer of heat and prevent the user from being scalded.

[0085] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.

[0086] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
