Both the connector 333 and the abutment 332 extend from the housing 31 and toward the upper tray assembly 10. Wherein connecting piece 333 is connected with last overware subassembly 10, and butt piece 332 passes under the drive of floating piece 331 and dodges through-hole 318 and move up the time butt overware subassembly 10 along preset direction, drives simultaneously through connecting piece 333 and butt piece 332 and goes up overware subassembly 10 and move along preset direction to the stability of going up overware subassembly 10 removal has been guaranteed.

Wherein, referring to fig. 1, the rotational connection of the upper tray assembly 10 and the lower tray assembly 20 is accomplished by at least one hinge assembly 50. The hinge assembly 50 includes a hinge 51 connected to the upper tray assembly 10, and a hinge seat 52 connected to the lower tray assembly 20; the hinge member 51 is rotatably connected with the hinge seat 52, and the hinge member 51 rotates on the hinge seat 52 with its own rotation center; the connection end of the connection 333 is connected to the hinge 51.

When the frying and baking machine is used, the user can first drive the floating assembly 33 to move up to the first height position by the driving assembly 32 according to the volume of the food to be baked, and the accommodating cavity 317 has the first height. The hinge assembly 50 is utilized to realize the rotation of the upper baking tray assembly 10 relative to the lower baking tray assembly 20, the frying and baking cavity 40 is opened, the food to be baked is placed in the frying and baking cavity 40, and the upper baking tray assembly 10 is covered again. During the food baking process, the volume of the food is continuously increased, and at this time, two ways of adjusting the distance between the upper and lower

baking tray assemblies

10 and 20 may be provided: the first is that the user rotates the drive shaft 323 and the drive assembly 32 moves the float assembly 33 further up to a second height position (the second height being greater than the first height) where the receiving chamber 317 has a second height to accommodate the expanding food. In this case, the power for the upward movement of the upper tray assembly 10 is derived from the driving assembly 32. The second is that the support 325 of the driving component 32 keeps the first height unchanged, so that the food expands against the upper heating surface 11 of the upper baking tray component 10, and the upper baking tray component 10 moves upwards, and when the upper baking tray component 10 moves upwards, the floating component 33 is further driven to move upwards by the connecting piece 333, so that the floating process of the floating component 33 is realized, and the floating component 33 floats upwards with the first height as a starting point. In this case, the power for the upward movement of the upper grill pan assembly 10 is derived from the expanded food.

It should be noted that, during the heating process of the food, the user may also adjust the floating reference height of the driving component 32 to drive the floating component 33 according to the expansion rate of the food, for example, in the above description, the floating component 33 floats based on the first height, if in some possible embodiments, the expansion rate of the food is higher, the driving component 32 may be used to drive the floating component 33 to the second height in advance, so that the floating reference height of the floating component 33 is the second height, that is, different adjustment gears of the driving component 32 are adjusted. In practical use, the user can adjust the heights of the driving component 32 and the floating component 33 according to the volume of the food before being roasted and the expansion rate in the roasting process, and the specific values of the heights are not limited in this embodiment, and are not limited to the above examples.

As an implementation manner, the connecting piece 333 of the floating component 33 is connected with the upper baking tray component 10 through the hinge piece 51, and the floating component 33 is driven by the upper baking tray component 10 to move to at least two floating positions with different heights along a preset direction, wherein the distance between the adjacent floating positions is 1-10mm. The floating assembly 33 provided in this embodiment may also have different floating gear positions, that is, floating positions with different heights, and the specific value of the distance between adjacent floating positions may be adjusted as required, which is not limited in this embodiment.

Specifically, referring to fig. 8 and 14, the abutting point of the abutting end of the abutting piece 332 of the floating unit 33 on the upper tray unit 10 and the connecting point of the connecting piece 333 on the upper tray unit 10 are disposed at a distance from each other on the upper tray unit 10.

It should be noted that, the connection point of the connection part 333 and the upper tray assembly 10 may be located on the outer peripheral wall of the upper tray assembly 10, and the abutment end of the abutment part 332 may be located on the side of the central position of the upper tray assembly 10 relative to the connection point, so that the connection part and the abutment end are located at different positions of the upper tray assembly 10. In practical use, the abutment and connection points may also be the rest of the various positions on the upper tray assembly 10, which is not limited in this embodiment nor to the above examples.

When the frying and baking machine is in use, the connecting piece 333 is connected with the upper baking tray assembly 10, the upper baking tray assembly 10 is fixed from the position of the connecting point, and the floating piece 331 drives the abutting piece 332 to push the abutting piece 332 to move upwards along the preset direction from the position of the abutting point when the abutting piece 332 abuts against the upper baking tray assembly 10. Based on that the connecting piece 333 and the abutting piece 332 are connected to the floating piece 331, when the floating component 33 pushes the upper baking tray component 10, the connecting piece 333 and the floating piece 331 form stable abutting connection and connection relation similar to triangle on the upper baking tray component 10, and the floating piece 331, the connecting point and the abutting point respectively form three vertexes of triangle, so that the upper baking tray component 10 is moved by a stable connecting structure, the stability of the connection and the moving process is ensured, the thickness of the baking machine is consistent in use, and uneven thickness can not occur.

As described above, the driving component is utilized to drive the supporting component to move up and down so as to realize the lifting of the upper baking tray component, and then the connecting component and the supporting component are utilized to move up and down together so as to keep the upper baking tray component to move up and down relative to the horizontal. Through the structure, the whole horizontal up-and-down movement of a long force arm (such as a floating assembly and an upper baking tray assembly) can be realized under a short action moment (such as a driving piece and a driven piece); and the free floating of the upper baking tray group can be realized while the up-and-down lifting movement is realized.

As a possible embodiment, the distance between the abutment point of the abutment end on the upper tray assembly 10 and the connection point of the connection end on the upper tray assembly 10 is shown as a distance in fig. 14, and the value of the distance a may be 20-80mm. Preferably, the distance a may have a value in the range of 35-45mm. In practical use, the user may select a specific value of the distance between the abutment point and the connection point within the above-mentioned range of values, and the specific value is not limited in this embodiment.

Further, referring to fig. 11, in the driving assembly 32 provided in this embodiment, the driven member 322 has a top surface facing the floating assembly 33, the floating member 331 has a floating surface facing the driving assembly 32, and the driven member 322 abuts against the floating assembly 33 under the driving action of the driving member 321.

It should be noted that, in the present embodiment, the floating member 331 and the driven member 322 achieve a mutually abutting relationship in a surface-to-surface manner, and the abutting surface can effectively increase the abutting area of the two relative to the abutting point, so as to ensure the stability of the driven member 322 when driving the floating member 331 to move, and effectively avoid the problem of tilting or deflecting when the floating member 331 and the upper bakeware assembly 10 move upwards.

As a possible embodiment, the upper heating surface 11 is disposed on the side of the upper baking tray assembly 10 facing the frying cavity 40, the lower heating surface 21 is disposed on the side of the lower baking tray assembly 20 facing the frying cavity 40, and when the upper baking tray assembly 10 and the lower baking tray assembly 20 are fastened to each other, the upper heating surface 11, the lower heating surface 21, the abutting surface and the floating surface are all parallel to each other.

It should be noted that, based on the description in the driving assembly 32, the upper heating surface 11 and the lower heating surface 21 are parallel to each other, so that the heating uniformity of food can be ensured, that is, the upper heating surface 11, the lower heating surface 21, the abutting surface and the floating surface are parallel to each other, so that not only can the distances between each position in the frying and baking cavity 40 and the upper heating surface 11 and the lower heating surface 21 be equal, and thus, the heating uniformity of food before the height adjustment of the frying and baking machine can be ensured, but also the abutting surface and the floating surface can be parallel to the upper heating surface 11 (or the lower heating surface 21) at the same time, and thus, the distances between each position in the frying and baking cavity 40 and the upper heating surface 11 and the lower heating surface 21 are equal in the moving process of the upper baking pan assembly 10, and thus, the heating uniformity of food in the height adjustment process of the frying and baking taste of food can be ensured to the greatest extent.

Specifically, referring to fig. 11, the floating assembly 33 provided in this embodiment may further include at least one floating guide assembly 334, where the guiding direction of the floating guide assembly 334 is in a preset direction; the float 331 cooperates with the float guide assembly 334 and moves in a predetermined direction under the urging of the drive assembly 32.

The floating guide assembly 334 comprises a floating guide through hole 334a formed in the shell 31, the abutting piece 332 penetrates through the floating guide through hole 334a and extends towards the upper baking tray assembly 10, and a floating guide bearing is further arranged between the floating guide through hole 334a and the abutting piece 332; the extending directions of the abutting piece 332 and the floating guide through hole 334a are both located in a preset direction, and the abutting piece 332 is driven by the floating piece 331 to move along the preset direction.

It should be noted that, when the driving assembly 32 drives the floating assembly 33 to move along the preset direction, the floating guide through hole 334a in the floating guide assembly 334 can limit the moving path and direction of the abutting member 332, so as to prevent the abutting member 332 from deflecting or dislocating, thereby ensuring that the abutting member 332 can accurately abut against the abutting point of the upper bakeware assembly 10, and ensuring the stability when the abutting member 332 and the connecting member 333 drive the upper bakeware assembly 10 to move upwards.

As a possible embodiment, when the driving assembly 32 does not abut against the floating member 331, the distance between the abutting end of the abutting member 332 and the upper bakeware assembly 10 is the distance shown in fig. 14 b, and the value of the distance b ranges from 1 mm to 50mm. Preferably, the distance b is in the range of 1-35mm. The distance b may determine the floating range of the upper tray assembly 10, so in practical use, the user may define a specific value of the distance between the abutting end and the upper tray assembly 10 within the above range of values according to the expansion degree of the food, which is not limited in this embodiment.

As a possible embodiment, the abutment 332 is a rod-like structure, and the diameter of the abutment 332 is 3-20mm. Preferably, the abutment 332 has a diameter of 5-8mm. The abutting member 332 may be a rod-shaped structure, which may be a round rod, and the abutting member 332 needs to abut against the top baking tray assembly 10 and move the same, so that if the diameter of the abutting member 332 is small, the mechanical strength of the abutting member is insufficient to ensure that the abutting member 10 moves, and if the diameter of the abutting member is too large, the manufacturing cost of the frying and baking machine is increased, and the volume of the whole height adjusting assembly 30 is increased. Therefore, in practical use, the user may select a specific value of the diameter of the abutment 332 within the above range of values according to the material and the practical requirement of the abutment 332, and the present embodiment is not limited to the specific value. Further, the abutment 332 may also be a square rod or other irregularly shaped rod-like structure, in which case the cross-sectional area of the abutment 332 may be limited while ensuring the mechanical strength and manufacturing cost of the abutment.

As an alternative embodiment, the floating assembly 33 includes a plurality of floating guide assemblies 334, and the plurality of floating guide assemblies 334 are disposed in the receiving chamber 317 at intervals in a direction perpendicular to the preset direction. The floating assembly 33 provided in this embodiment is provided with the plurality of floating guide assemblies 334, and the plurality of floating guide assemblies 334 are arranged at intervals, so that the moving direction of the abutting member 332 can be limited at each position along the direction perpendicular to the preset direction, and the moving stability of the connecting member 333 and the upper bakeware assembly 10 abutting against the connecting member 333 is improved.

Referring to fig. 12 and 13, the height adjusting assembly 30 may further include a locking assembly 60, the locking assembly 60 abutting the driving member 321 for locking or unlocking the abutting state of the driving member 321 against the floating assembly 33. When the frying and baking machine provided in this embodiment is used, the driving component 32 drives the floating component 33 to adjust the height of the whole frying and baking cavity 40, and food is placed in the frying and baking cavity 40 while maintaining the height, and the floating height of the floating component 33 is adjusted according to the volume change of the food baking process, so that the baking basis is completed while maintaining the height of the frying and baking cavity 40. The height adjusting assembly 30 of the present embodiment locks the abutting state of the driving assembly 32 against the floating assembly 33 by the locking assembly 60, so as to achieve the purpose of maintaining the height of the frying and roasting cavity 40.

Specifically, the locking assembly 60 is positioned in the mounting cavity 325a of the support 325, and the locking assembly 60 may include a locking body 61 having a receiving groove 611, and a locking member 63 and at least one elastic member 62 positioned in the receiving groove 611, with a notch of the receiving groove 611 facing the driving member 321. The two ends of the elastic member 62 are respectively connected with the inner wall of the accommodating groove 611 and the locking member 63, and at least part of the locking member 63 extends out of the notch of the accommodating groove 611 under the elastic force of the elastic member 62 and abuts against the driving member 321.

It should be noted that, the notch of the accommodating groove 611 faces the driving member 321, and the shape and the size of the inner cavity of the accommodating groove 611 and the notch can be set according to the requirement, which is not limited in this embodiment. The elastic member 62 disposed inside the accommodating groove 611 may be a spring and/or a shrapnel, one end of the elastic member 62 may be connected to the locking member 63, specifically may be connected to an end portion of the locking member 63 facing the bottom of the accommodating groove 611, and the other end of the elastic member 62 may be connected to an inner wall of the accommodating groove 611, specifically may be connected to the bottom of the accommodating groove 611. At least part of the locking member 63 protrudes from the notch to abut against the driving member 321, thereby forming a locked state. The elastic member 62 is now always in a compressed state.

Wherein, a stop portion (not shown) may be further disposed on a side wall of the locking member 63, and the stop portion may stop at a notch position when the locking member 63 moves toward a notch side of the receiving groove 611, so as to prevent the locking member 63 from being separated from the receiving groove 611, thereby maintaining structural stability of the locking assembly 60. The distance between the stopper and the notch defines the length of the locking assembly 60 extending out of the notch, so in actual use, the user may set the depth of the receiving groove 611 and the distance between the stopper and the notch according to the distance between the end of the locking member 63 and the driving member 321, which is not limited in this embodiment.

Specifically, the driving member 321 and the locking member 63 are abutted by the engaging assembly 70, and the engaging assembly 70 includes an engaging groove 71 provided on one of the locking member 63 and the driving member 321, and an engaging member 72 provided on the other of the locking member 63 and the driving member 321. In the present embodiment, the engaging groove 71 is provided on the driving member 321, and the engaging member 72 is provided on the locking member 63, for example, and the user may further need to change the installation positions of the engaging groove 71 and the engaging member 72 in actual use, which is not limited in this embodiment.

The driving member 321 is provided with a plurality of engaging grooves 71, and the engaging grooves 71 are disposed at intervals along the outer circumference of the driving member 321. Since the driver 321 rotates along its own axis when in operation, the abutment positions with the driver 321 are respective positions on the outer periphery of the driver 321. The plurality of engaging grooves 71 are arranged at intervals along the outer periphery of the driving member 321, so that different engaging grooves 71 can be engaged with the engaging member 72 alternatively when the driving member 321 rotates. When the engaging piece 72 is engaged in the engaging groove 71, the locking state of the locking assembly 60 is formed, and when the engaging piece 72 is disengaged from the engaging groove 71, the unlocking state of the locking assembly 60 is formed.

It should be noted that the number of the engaging grooves 71 and the distance between the adjacent engaging grooves 71 may be set as required, and the present embodiment is not limited thereto.

The operation of the locking assembly 60 will be described with reference to fig. 12, in which fig. 12 shows a state in which the engaging member 72 of the locking assembly 60 is engaged in the engaging groove 71, and the locking assembly 60 is locked to the driving assembly 32, and the driving assembly 32 is naturally subjected to the locking force of the locking assembly 60, so as to maintain the engaged state of the driving gear and the driven rack. When the height of the follower 322 of the driving assembly 32 needs to be moved up, the driving shaft 323 can be rotated anticlockwise, at this time, the driving gear rotates, the clamping force of the clamping assembly 70 is gradually reduced, the clamping member 72 and the clamping groove 71 are separated from each other, and when the driving gear rotates, the clamping member 72 is clamped in the adjacent clamping groove 71 in the clockwise direction outside the driving gear Zhou Shun again, so that the locking state is realized again. The driving gear rotates anticlockwise, so that the driven rack is driven to move upwards.

As an embodiment, the engagement groove 71 is formed on the driving gear of the driving member 321 or the driving shaft 323. The above-mentioned working process of the locking assembly 60 is described by taking the engagement groove 71 formed on the driving member 321 as an example, and in practical use, the engagement groove 71 may be formed on the driving shaft 323, and the user may set the engagement groove according to the positional relationship between the locking assembly 60 and the driving gear and the driving shaft 323, which is not limited in this embodiment.

As an implementation manner, the engagement surfaces of the engagement groove 71 and the engagement member 72 are arc-shaped surfaces or V-shaped surfaces. It should be noted that, the engaging surfaces of the engaging groove 71 and the engaging member 72 need to ensure that the engaging surfaces can be easily engaged or disengaged, when the engaging surface is an arc surface, the engaging surface is an arc structure, and when the engaging surface is a V-shaped surface, the engaging surface is a chamfer structure, which is beneficial for the engaging member 72 to be disengaged or engaged into the engaging groove 71, thereby improving the operation convenience of the locking assembly 60.

It should be noted that the hinge member 51 may be connected to the upper tray rotation shaft in the upper tray assembly 10, and the hinge seat 52 may be connected to the lower tray rotation shaft in the lower tray assembly 20. The upper baking tray assembly 10 and the lower baking tray assembly 20 are connected through the hinge assembly 50, and the hinge piece 51 rotates in the hinge seat 52 to drive the upper baking tray assembly 10 to rotate relative to the lower baking tray assembly 20, so that the operation process of the frying and baking machine is simplified, the acting force required by the opening and closing processes of the frying and baking cavity 40 of the frying and baking machine is reduced, and the operability of the frying and baking machine is improved.

Specifically, the hinge base 52 has a hinge chamber 521 therein, the extending direction of the hinge chamber 521 is in a predetermined direction, and the hinge 51 is connected in the hinge chamber 521. The hinge 51 is connected with the height adjusting assembly 30, and when the height adjusting assembly 30 adjusts the distance between the upper and

lower tray assemblies

Further, the connection end of the connection 333 of the floating assembly 33 is connected with the hinge 51. When the floating assembly 33 moves toward the upper tray assembly 10 under the abutting action of the follower 322, the abutting end abuts against the upper tray assembly 10.

It should be noted that, the hinge cavity 521 may have an oblong structure, and the extending direction thereof is located in a predetermined direction. When the height adjusting assembly 30 is operated, the driving assembly 32 drives the floating assembly 33 to move upwards, and the connecting member 333 can drive the hinge member 51 to move along the preset direction in the hinge cavity 521. When the float assembly 33 is in the first height position, the hinged connection of the upper tray assembly 10 and the lower tray assembly 20 may still be achieved based on the positioning of the hinge 51 within the hinge cavity 521. The hinge assembly 50 can adapt to the adjustment process of the height adjusting assembly 30, and ensures the structural stability of the frying and baking machine.

As one possible embodiment, a plurality of hinge assemblies 50 are provided between the upper and

lower tray assemblies

By providing the first and second mounting

portions

311a and 311b on the outer wall surfaces of different orientations, respectively, the housing 31 can be fixed from various directions, thereby improving the connection stability of the housing 31 and the lower grill pan assembly 20.

Further, the abutting piece 332 of the floating component 33 is directly abutted against the upper baking pan component 10, and in the conventional baking machine, in order to avoid the problem of food pasting, a release coating is generally disposed on the upper heating surface 11 and/or the lower heating surface 21. The abutting piece 332 is repeatedly abutted against the upper baking tray assembly 10 for a long time, so that the surface paint coating of the upper baking tray assembly 10, which is close to the rotating shaft of the upper baking tray, is most likely to be scratched, the integrity of the anti-sticking coating is sometimes affected, the attractiveness of the frying and baking machine is reduced, and the problem that food is stuck in the scratched area is caused.
