Description

Technical Field

[0001] The present application relates to the field of small household appliances, and particularly to a griddle. Background Art

[0002] In daily life, a griddle is usually used for cooking and making pancake-like foods, and the food in the heating tubes of the first baking tray assembly and / or the second baking tray assembly is heated. During the cooking process, the food will expand as the temperature rises, so that the height of the food gradually increases. If the height of the cooking cavity of the griddle is small, it will block the expansion of the food, and the food cannot achieve a fluffy and crispy texture; if the height of the cooking cavity is too large, it will increase the volume of the griddle, making it difficult to carry or store.

[0003] In order to be able to adjust the height of the cooking cavity, in the prior art, such as US Patent US05927539, a guide member that can slide up and down is provided at the hinge device to achieve the adjustment of the height of the upper cover. However, because the upper cover is too heavy, the guide member cannot lift the upper cover; or the manufacturing requirements for the guide member are relatively high, and the manufacturing cost of the griddle is relatively high. There is also, such as Chinese Utility Model Patent CN202220196511.5, in which the guide member and the spring are set as an integral structure, so that the upper cover rises as the height of the food increases during the food expansion process, so that the food can achieve a fluffy and crispy texture. However, when the guide member and the spring are set as an integral 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 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 situation that the upper cover automatically closes due to the elastic force of the spring may occur, 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 arms of the lifting device and the hinge device are relatively long, during the rising process of the upper cover, the front cover of the upper cover will shake, affecting the user experience. Such as Chinese Utility Model Patent CN218606229U, a support block is arranged on the lower baking tray assembly, and different sides are abutted against the upper / lower baking tray assembly by rotating the support block, so as to change the height of the cooking cavity.

[0004] However, in the prior art, whether the lifting device is in the state of adjusting the cooking cavity or not in the state of adjusting the cooking cavity, the lifting device is in contact with the upper baking tray assembly or the lower baking tray assembly. In this way, the upper / lower baking tray assembly will exert a continuous and uninterrupted force on the lifting device, so that the lifting device will reach its own fatigue strength and then break. Summary of the Invention

[0005] To solve the above technical problems, the present application discloses a griddle. When the cooking cavity height is not adjusted, the lifting device is not in contact with the baking pan assembly. When the cooking cavity height is adjusted, the lifting device is in contact with the baking pan assembly, reducing the force exerted by the upper / lower baking pan assembly on the lifting device.

[0006] A griddle of the present application includes a first baking pan assembly and a second baking pan assembly. The first baking pan assembly and the second baking pan assembly enclose a cooking cavity. A lifting device for adjusting the height of the cooking cavity is provided on the griddle. The lifting device further includes:

[0007] A connecting member provided on the first baking pan assembly;

[0008] A moving member provided on the connecting member. The moving member has a supporting position between the first baking pan assembly and the second baking pan assembly, and an avoiding position outside the first baking pan assembly and the second baking pan assembly. The moving member moves radially on the first baking pan assembly to switch between the supporting position and the avoiding position, thereby changing the height of the cooking cavity.

[0009] The following also provides several optional ways, which are not additional limitations to the above overall solution, but only further supplements or preferences. Without technical or logical contradictions, each optional way can be combined with the above overall solution alone, or multiple optional ways can be combined with each other.

[0010] Optionally, the first baking pan assembly includes a platform extending radially outward along the griddle. The connecting member is provided on one side of the platform. The moving member moves to the other side of the platform and is in the supporting position.

[0011] Optionally, the first baking pan assembly includes a first housing and a first baking pan placed in the first housing. The first baking pan has a side edge, and the upper edge of the side edge extends outward to form a flanging. The platform is the flanging.

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

[0013] Optionally, the moving member includes a supporting surface abutting against the second baking pan assembly. At least one step is provided on the supporting surface. The second baking pan assembly abuts against the supporting surface or the step to adjust the height of the cooking cavity.

[0014] Optionally, the lifting device includes a sliding channel and a sliding rib. The moving member moves on the connecting member through the cooperation of the sliding channel and the sliding rib.

[0015] Optionally, the moving member includes a supporting surface, a first side surface longitudinally extending along both sides of the supporting surface, the connecting member has a second side surface extending longitudinally, and the first side surface is located outside the second side surface; ribs extending inward are provided on the first side surface, and the ribs, the first side surface and the supporting surface form a strip-shaped channel. A sliding rib is provided on the second side surface, and the sliding rib is embedded in the strip-shaped channel. The strip-shaped channel and the sliding rib cooperate to allow the moving member to move on the connecting member.

[0016] Optionally, a first limiting structure is provided on the moving member, and the first limiting structure abuts against the platform to limit the inward movement of the moving member, and the moving member is located at the supporting position; and / or, a second limiting structure is provided on the connecting member, and the moving member abuts against the second limiting structure to limit the outward movement of the moving member, and the moving member is located at the avoiding position.

[0019] In the grilling machine of the present application, the first baking tray assembly and the second baking tray assembly are separated by the radial movement of the moving member, thereby changing the height of the cooking cavity. In this way, only when the moving member separates the first baking tray assembly and the second baking tray assembly, the upper / lower baking tray assembly will exert a force on the lifting device, so that the force exerted by the upper / lower baking tray assembly on the lifting device can be reduced.

[0043] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0044] It should be noted that when a component is referred to as being "connected" to another component, it can be directly connected to the other component or there may also be an intermediate component. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component at the same time.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the description of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the related listed items.

[0046] The griddle 100 places food on the first baking tray assembly 200. After the griddle 100 is powered on, the heating tubes work to generate heat, and the heat generated by the heating tubes is transferred to the food to heat the food. During the process of heating the food, in order to create a high-temperature and high-heat environment for the food, usually the first baking tray assembly 200 and the second baking tray assembly 300 are covered together to form a sealed cooking cavity 400 to heat the food placed inside, which can accelerate the cooking time of the food. When making foods such as flatbreads, since flatbreads contain ingredients such as yeast, during the cooking process, the flatbread will gradually puff up and its height will gradually increase. At this time, if the height of the cooking cavity 400 is relatively low, the flatbread placed on the first baking tray 201 will come into contact with the second baking tray assembly due to puffing up. In this way, the second baking tray assembly 300 will hinder the puffing height of the food, making the food hard and dry.

[0047] In order to be able to change the height of the cooking cavity 400, in the prior art, a retractable movable member is provided on the first baking tray assembly 200. During the cooking process, when the puffing height of the food is relatively large, the second baking tray assembly 300 is pushed upward by adjusting the movable member, separating the first baking tray assembly 200 and the second baking tray assembly 300, and adjusting the height of the cooking cavity 400. However, during the upward pushing process, most of the weight of the second baking tray assembly 300 will fall on the movable member, causing the movable member to bear a relatively large weight. The movable member is arranged on the opposite side of the hinge device of the first baking tray assembly 200 and the second baking tray assembly 300. In this way, during the process of changing the height of the cooking cavity 400, the movable member will always push against the second baking tray assembly 300, and the movable member extends out from the perforation on the first baking tray assembly 200 to abut against the second baking tray assembly 300. The user provides a force for the movable member to extend upward through the perforation by turning the knob. After the movable member passes through the perforation and abuts against the second baking tray assembly 300, the force for the movable member to rise is provided by the knob to drive the second baking tray assembly 300 to rise, thereby adjusting the height of the cooking cavity 400. This will cause most of the gravity of the second baking tray assembly 300 to press on the movable member, and in order not to interfere with the user's observation of the food during cooking or to facilitate flipping of the food, the movable member is usually made relatively small, resulting in the movable member being able to bear a relatively small pressure and not being able to support the rise and fall of the second baking tray assembly 300 for a long time.

[0048] Alternatively, in other existing technologies, in order to be able to adjust the height of the cooking cavity 400, a support block is provided on the side of the griddle 100, and the height of the cooking cavity 400 is adjusted by rotating the support block. The support block is set to be strip-shaped, a groove 503 is provided on the second baking tray assembly 300, the support block is provided at the groove 503, and the support block further includes a first surface, a second surface, a third surface and a fourth surface arranged in clockwise order, wherein the first surface and the third surface are arranged oppositely. When the first baking tray assembly 200 and the second baking tray assembly 300 are in contact with each other, the first surface of the support block is in contact with the second baking tray assembly 300, and the third surface is in contact with the first baking tray 201; when the first baking tray assembly 200 and the second baking tray assembly 300 are in contact with each other, the second surface and the fourth surface of the support block that are provided on the second baking tray assembly 300 and are 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 the clockwise direction, so that the fourth surface is in contact with the second baking tray assembly 300, the second surface is in contact with the first baking tray assembly 200, and the first surface abuts against the side wall of the groove 503, thereby changing the height of the cooking cavity 400. In this way of adjusting the height of the cooking cavity 400 by rotating the support block itself, whether the first baking tray assembly 200 and the second baking tray assembly 300 are in contact with each other or when the height of the cooking cavity 400 needs to be adjusted, at least one surface of the support block is in contact with the second baking tray assembly 300. Especially during 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 on the support block during the rotation of the support block. 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 exert a continuous and repeated force on the support block, so that the support block quickly reaches its own fatigue strength and then breaks.

[0049] Such as Figure 1 , Figure 2 and Figure 8As shown, in order to reduce the force exerted by the baking pan 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 the fatigue strength can be slowed down, and the service life of the lifting device 500 can be extended. An electric griddle 100 of the present application includes a first baking pan assembly 200 and a second baking pan assembly 300. The first baking pan assembly 200 and the second baking pan assembly 300 enclose to form a cooking cavity 400. A lifting device 500 for adjusting the height of the cooking cavity 400 is provided on the electric griddle 100. The lifting device 500 further includes: a connecting member 501 provided on the first baking pan assembly 200; a moving member 502 provided on the connecting member 501. The moving member 502 has a supporting position between the first baking pan assembly 200 and the second baking pan assembly 300, and an avoiding position outside the first baking pan assembly 200 and the second baking pan assembly 300. The moving member 502 moves radially on the first baking pan assembly 200 to switch between the supporting position and the avoiding position, thereby changing the height of the cooking cavity 400.

[0050] In this embodiment, the first baking pan assembly 200 and the second baking pan assembly 300 enclose to form a cooking cavity 400, and the lifting device 500 is used to adjust the height of the cooking cavity 400. The electric griddle 100 is usually placed on a tabletop. The first baking pan assembly 200 is placed parallel on the tabletop, and the second baking pan assembly 300 is fastened on the first baking pan assembly 200. Food is placed on the first baking pan assembly 200 and heated by a heating tube. The second baking pan assembly 300 can be flipped and covered on the first baking pan assembly 200, which can not only heat the upper surface of the food, but also prevent the heat loss of the cooking cavity 400. Generally, the baking pan assembly that is placed flat on the tabletop and on which food is placed can be called the lower baking pan assembly; the baking pan assembly that is fastened on the lower baking pan assembly and can be flipped and covered can be called the upper baking pan assembly; the first baking pan assembly 200 in the present application is the lower baking pan assembly, and the second baking pan assembly 300 is the upper baking pan assembly. Of course, since it is easy to convert whether the lifting device 500 is provided between the upper baking pan assembly and the lower baking pan assembly in the present application, the first baking pan assembly 200 in the present application can also be the upper baking pan assembly, and the second baking pan assembly 300 can also be the lower baking pan assembly.

[0051] 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.

[0052] 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 away from the cooking cavity 400 at this time, and the moving member 502 is not in 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, first open the second baking tray assembly 300, and then move the moving member 502 in the direction close to the cooking cavity 400, so that the moving member 502 is in contact with the first baking tray assembly 200, and then cover the second baking tray assembly 300, so that the moving member 502 is in contact with the second baking tray assembly 300. At this time, the moving member 502 is in contact with the first baking tray assembly 200 and the second baking tray assembly 300. 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 enough space for the expansion of the food. And when the moving member 502 is opened between the first baking tray assembly 200 and the second baking tray assembly 300, it first extends into the middle of 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 there is a moving member 502 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 will not be completely closed, but the moving member 502 supports the second baking tray assembly 300 to make the first baking tray assembly 200 and the second baking tray assembly 300 spaced apart. In this way, the moving 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 the original height, the moving member 502 is not in contact with the first baking tray assembly 200 and the second baking tray assembly 300, so that the time of the force exerted by the second baking tray assembly 300 on the moving member 502 can be reduced, and the time for the moving member 502 to reach its own fatigue strength can be increased; at the same time, the moving member 502 lifts the first baking tray assembly 200 and the second baking tray assembly 300 by means of support, while in the prior art, most of them lift the second baking tray assembly 300 by the moving member 502. During the lifting process, the second baking tray assembly 300 will exert a greater pressure on the moving member 502, so that the moving member 502 reaches its own fatigue strength faster.

[0053] 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 the 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 jointly move 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 provided. During the movement of the moving member 502, the connecting member 501 is fixed on the first baking tray assembly 200 without moving, and only the moving member 502 makes a relative movement on the connecting member 501, and the support for the second baking tray assembly 300 is realized only through the radial movement of the moving member 502.

[0054] The portion of the moving member 502 that is in contact with the second baking tray assembly 300 and is used to space the first baking tray assembly 200 and the second baking tray assembly 300 is strip-shaped. In the prior art, when the rotating lifting device 500 lifts the second baking tray assembly 300, in order to enable the user to lift the second baking tray assembly 300 with less force, the area of the contact portion between the lifting device 500 and the second baking tray assembly 300 is small. In this way, although the user can lift the lifting device 500 and the second baking tray assembly 300 together with less force, because 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 this small area. In this way, the acting force of the second baking tray assembly 300 on the lifting device 500 per unit area is large, and it is easy for the lifting device 500 to reach its own fatigue strength. In this embodiment, the portion of the moving member 502 in contact with the second baking tray assembly 300 is set to be strip-shaped with a large contact area. In this way, when the weight of the second baking tray assembly 300 presses on the strip shape with a large area, the strip shape will disperse the acting force of the second baking tray assembly 300 on the lifting device 500, so that the acting force of the second baking tray assembly 300 on the lifting device 500 per unit area is small, and 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.

[0055] When the second baking tray assembly 300 presses on the lifting device 500, if the lifting device 500 alone is relied on to support the second baking tray assembly 300, the second baking tray assembly 300 may deform or even damage the lifting device 500. To provide more support for the lifting device 500 so that the lifting device 500 can better support the second baking tray assembly 300, the first baking tray assembly 200 includes a first baking tray 201, and the connecting member 501 and the moving member 502 clamp the first baking tray 201. The first baking tray assembly 200 includes a platform 202 formed by extending radially outward along the griddle 100. The connecting member 501 is disposed on one side of the platform 202, and the moving member 502 moves to the other side of the platform 202 and is located at the supporting position. In the prior art, the first baking tray assembly 200 usually only plays a role of fixedly connecting the lifting device 500 and has a relatively small supporting effect on the lifting device 500. For example, the movable member that can be telescoped in the first baking tray assembly 200 mentioned above, the first baking tray assembly 200 only plays a role of fixing the movable member, and all the force for supporting the second baking tray assembly 300 is borne by the movable member. In this embodiment, by arranging the first baking tray 201 to extend 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 jointly support the second baking tray assembly 300. The first baking tray 201 clamped between the connecting member 501 and the moving member 502 of the lifting device 500, when the second baking tray assembly 300 is placed on the upper end of the moving member 502, the gravity of the second baking tray assembly 300 will sequentially pass through the moving member 502, the first baking tray 201, and the connecting member 501. In this way, the gravity of the second baking tray assembly 300 is gradually shared after passing through the three components, and the gravity of the second baking tray assembly 300 borne by each component will be reduced a lot. For the moving member 502 that bears the most gravity, because the first baking tray 201 supports the moving member 502 below, the moving member 502 is not suspended on the first baking tray assembly 200. Instead, when the second baking tray assembly 300 presses down on the moving member 502, the first baking tray 201 will support the moving member 502. Since the first baking tray 201 needs to hold food and is heated at a high temperature by a heating tube, the strength of the first baking tray 201 is much greater than that of the lifting device 500. The weight of the second baking tray assembly 300 is much greater than the weight of the moving member 502. When the second baking tray assembly 300 applies pressure to the moving member 502, the moving member 502 deforms. The deformed moving member 502 is blocked by the first baking tray 201, reducing the deformation amount of the moving member 502, thereby helping the moving member 502 to complete the support of the second baking tray assembly 300.Without the support of the first baking tray 201 , when the moving member 502 is subjected to the downward pressure of the second baking tray assembly 300 whose gravity is much greater than its own gravity, the moving member 502 may be deformed or broken because it cannot withstand the pressure of the second baking tray assembly 300 .

[0056] like Figure 11 As shown, the top surface 523 of the platform 202 abuts against the cross-blocking surface 522 of the moving member 502, and the moving 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 moving member 502, so that the pressure of the second baking tray assembly 300 can be withstood.

[0057] 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 moving member 502 moves to the supporting position, and the moving member 502 abuts against the surface of the platform 202; the moving member 502 moves to the avoiding position, and the moving member 502 is located outside the platform 202.

[0058] 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.

[0059] 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 interior of the lifting device 500, the moving member includes a groove 503. A first arm 504 is provided at the lower end of the groove 503, and the first arm 504 is in contact with 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 is in contact with 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, then the lifting device 500 cannot be firmly fixed on the first baking tray 201 and is prone to shaking. Seriously, the lifting device 500 will fall off the first baking tray 201. In order to firmly clamp the first baking tray 201 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. And the first arm 504 at the lower end of the groove 503 is in contact with the bottom side of the first baking tray 201, and the second arm 505 at the upper end of the groove 503 is in contact with 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, and the connecting member 501 can be either fixed on the first baking tray 201 or 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 moving member 502. When the height of the cooking cavity 400 needs to be adjusted, the second arm 505 is in contact with the top side of the first baking tray 201, thereby playing a supporting role for the second baking tray assembly 300. The first baking tray 201 is clamped in the middle of the lifting device 500 through the first arm 504 and the second arm 505, so as to reduce the gap between the first baking tray 201 and the lifting device 500.

[0060] As Figure 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 jamming due to unsmooth sliding, the lifting device 500 includes a sliding channel 506 and a sliding rib 507. The moving member 502 moves 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 moving 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 moving member 502. In the prior art, the lifting device 500 rotates by friction between the circumferential side surface and the first baking tray assembly 200. However, the height of the circumferential side surface of the lifting device 500 is different. After a long time, pits with different depths will be worn out on the first baking tray assembly 200 by the lifting device 500, which will affect the movement of the lifting device 500 on the first baking tray assembly 200. In order to always make one side inside the lifting device 500 as the sliding surface, the sliding channel 506 and the sliding rib 507 are provided, and the movement of the lifting device 500 between the first baking trays 201 is realized through the cooperation between the sliding channel 506 and the sliding rib 507.

[0061] In one embodiment, when the first arm 504 and the second arm 505 are integrated, the first arm 504 is arranged in a long strip block structure, and the lifting device 500 can move along the long side direction of the long strip block structure, so as to adjust the positional relationship between the lifting device 500 and the first baking tray 201. The second arm 505 is arranged in a cuboid structure, and the shorter side of the cuboid structure is arranged on both sides of the lifting device 500. In this way, the abutting surface that abuts against the second baking tray assembly 300 in the cuboid structure is a surface with a larger area, which can be used to disperse the acting force of the second baking tray assembly 300 on the lifting device 500.

[0062] Such as Figure 8 、 Figure 12 and Figure 13As shown, in one embodiment, when the first arm 504 and the second arm 505 are separately provided, the moving member 502 includes a support surface 512, a first side surface 513 longitudinally extending along both sides of the support surface 512. The connecting member 501 has a second side surface 514 extending longitudinally. The first side surface 513 is located outside the second side surface 514. A rib 515 extending inward is provided on the first side surface 513. The rib 515, the first side surface 513 and the support surface 512 form a strip-shaped channel 516. A sliding rib 507 is provided on the second side surface 514. The sliding rib 507 is embedded in the strip-shaped channel 516. The strip-shaped channel 516 and the sliding rib 507 cooperate to allow the moving member 502 to move on the connecting member 501. In a preferred embodiment, one end of the first arm 504 is fixed to the first baking tray 201 through a fastener 511, and the other end is provided with a sliding channel 506. 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 arranged in a U-shaped structure. The two sides of the U-shaped structure cooperate with the first arm 504, and the top wall of the U-shaped structure cooperates with the sliding channel 506 to realize the sliding of the moving member 502 relative to the connecting member 501.

[0063] As Figure 4 , Figure 10 and Figure 11As shown, in order to prevent the moving member 502 from extending too far into the cooking cavity 400 when moving, or from detaching from the lifting device 500 during movement, a first limiting structure 517 is provided on the moving member 502. The first limiting structure 517 abuts against the platform 202 to limit the inward movement of the moving member 502, and the moving member 502 is in the supporting position; and / or, a second limiting structure 518 is provided on the connecting member 501. The moving member 502 abuts against the second limiting structure 518 to limit the outward movement of the moving member 502, and the moving member 502 is in the avoiding position. The first limiting structure 517 is a step 519. When in the supporting position, the step 519 abuts against the flanging 203, thereby limiting the closest distance between the moving member 502 and the first baking tray 201. The second limiting structure 518 is a convex block 508, which limits the radial movement distance of the moving member 502. The convex block 508 and the first baking tray 201 cooperate with each other to limit the movement stroke of the moving member 502. The convex block 508 is used to limit the farthest distance between the moving member 502 and the first baking tray 201. If the convex block 508 is set at a relatively close distance from the first baking tray 201, the moving member 502 will not be able to completely detach from the contact with the first baking tray 201, so that the convex block 508 and the first baking tray 201 are always in an abutting state, and the first baking tray assembly 200 and the second baking tray assembly 300 cannot complete the abutting, and the first baking tray assembly 200 and the second baking tray assembly 300 are always in an interval state; if the convex block 508 is set at a relatively far distance, although the effect that the moving member 502 and the second baking tray assembly 300 cannot abut against each other can be achieved, the longer stroke will also cause the sliding channel 506 to be longer, thus causing the griddle 100 to occupy a larger space during transportation or storage, which is not convenient for the user to transport or store the griddle 100. Therefore, it is set that when the moving member 502 abuts against the convex block 508, the moving block does not abut against the first baking tray 201 exactly, so that the convex block 508 not only achieves the limiting effect on the moving member 502, but also reduces the space occupied by the griddle 100.

[0064] As Figure 14 shown, as a preferred embodiment, a step 519 is provided on the moving member 502. The vertical blocking surface 521 of the step 519 abuts against the platform 202 to limit the inward movement of the moving member 502, and the moving member 502 is in the supporting position between the first baking tray assembly 200 and the second baking tray assembly 300. The vertical blocking surface 521 abuts against the platform 202 in a surface-contact manner, which can well limit the movement distance of the moving member 502 when moving towards the supporting position.

[0065] As Figure 4As shown, in another embodiment, the moving member 502 includes a groove 503 into which the platform 202 extends; a convex channel 520 is provided on the connecting member 501, and a convex block 508 is provided on the moving member 502. The convex block 508 cooperates with the convex channel 520 to allow the moving member 502 to move on the connecting member 501.

[0066] In the prior art, the movable member on the griddle 100 is arranged on the opposite side of the hinge between the first baking tray assembly 200 and the second baking tray assembly 300. In this way, when the second baking tray assembly 300 is lifted by the movable member, since the movable member is far from the center of gravity of the second baking tray assembly 300, the movable member will shake when lifting the second baking tray assembly 300, affecting the lifting of the second baking tray assembly 300 by the movable member. Therefore, the lifting device 500 is arranged on the side of the griddle 100. In this embodiment, by arranging the lifting device 500 on the side of the griddle 100, the distance from the lifting device 500 to the center of gravity of the second baking tray assembly 300 can be reduced, so that the second baking tray assembly 300 can be lifted more smoothly.

[0067] In one embodiment, the lifting device 500 can be arranged as one, and the second baking tray assembly 300 is supported by a single lifting device 500 arranged on the side of the griddle 100. However, when the second baking tray assembly 300 is supported only by a single lifting device 500, the part of the second baking tray assembly 300 in contact with the lifting device 500 will be lifted, while the part of the second baking tray assembly 300 not in contact with the lifting device 500 will still be in contact with the first baking tray assembly 200, and the second baking tray assembly 300 cannot be completely lifted. Therefore, the lifting device 500 is arranged in two and symmetrically. In this way, when the height of the cooking cavity 400 needs to be adjusted, the two lifting devices 500 are simultaneously moved along the radial direction of the griddle 100, and the two lifting devices 500 are used together to space the second baking tray assembly 300 from the first baking tray assembly 200, preventing the situation where part of the second baking tray assembly 300 is lifted and part is still in contact with the first baking tray assembly 200.

[0068] The moving member 502 includes a supporting surface 512 that abuts against the second baking tray assembly 300. At least one step 509 is provided 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 swelling heights of different foods are different. If the height of the cooking cavity 400 is adjusted too high, the second baking tray assembly 300 cannot fit closely with the swollen food, thus affecting the heating efficiency of the second baking tray assembly 300 on the food. Therefore, a plurality of steps 509 are provided on the surface where the supporting portion 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 height of different cooking cavities 400 can be adjusted. When one step 509 is provided, the step abuts against the second baking tray assembly 300, and the cooking cavity can only change one height; when a plurality of steps 509 are provided, 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. At this time, the cooking cavity can change multiple heights.

[0069] When the lifting device 500 finishes supporting the second baking tray assembly 300 and needs to adjust the first baking tray assembly 200 and the second baking tray assembly 300 from the spaced state to the abutting state, the lifting device 500 needs to slide from the state of abutting against the first baking tray 201 to the state of being separated from the first baking tray 201. In order to enable the user to have a better feel during the sliding process, an elastic member 510 extending along the axial direction of the griddle 100 is provided on the platform 202, and an elastic force is provided to the moving member 502 through the elastic member 510. An elastic member 510 is provided on the first baking tray 201. The elastic member 510 extends along the axial direction of the first baking tray 201. One end thereof abuts against the sliding portion, and the other end abuts against the supporting portion.

[0070] As Figure 7 shown, the moving member 502 can be provided separately or can be a part of the folding piece 601 of the folding handle 600. The smooth folding piece 601 can provide a better sliding space for the lifting device 500.

[0071] 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 between 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 surface and the bottom surface of the platform 202 are utilized, so that the lifting device 500 can be arranged closely against the top surface and the bottom surface of the platform 202.

[0072] The technical features of the above-described embodiments can be combined arbitrarily.
