The utility model provides a frying and roasting machine 100.

Referring to fig. 1 and 2 in combination, in the embodiment of the present invention, the frying and roasting machine 100 includes:

the base assembly 10 comprises a base body 11 and a baking tray 13, wherein the baking tray 13 is rotatably arranged on the base body 11; and

the upper cover assembly 30 includes a cover 31, the cover 31 is connected to the base 11 and can be opened or closed on the baking tray 13, the cover 31 is provided with an air inlet 3131 and an air outlet 3133, the air inlet 3131 is communicated with the air outlet 3133 to form a heat dissipating air duct 310, and the heat dissipating air duct 310 is located in the cover 31.

In this embodiment, the base assembly 10 and the top cover assembly 30 may be substantially square, and the cover 31 and the base 11 may be made of plastic material with high structural strength and good heat dissipation. The base 11 is recessed to form a cavity 11a, and the grill pan 13 is disposed in the cavity 11a, so that when the cover 31 covers the base 11, the grill pan 13 rotates in the cavity 11a without interfering with the cover 31. The cover 31 and the base 11 can be fixed by hinge, so that the cover 31 can be turned over relative to the base 11 to cover or open the opening of the cavity 11 a.

The shape and size of the air inlet hole 3131 and the air outlet hole 3133 may be the same or different, for example, the shape of the air inlet hole 3131 and the air outlet hole 3133 may be circular or square, etc. The positions of the air inlet 3131 and the air outlet 3133 may be set on the top wall of the cover 31, or on the side wall of the cover 31.

It is understood that the position of the upper heating part 331 in the cover 31 should be outside the heat-dissipating air duct 310, so that the heat generated from the upper heating part 331 can be mostly transferred toward the grill pan 13, and the heat needs to pass through the heat-dissipating air duct 310 when the heat is transferred to the surface of the cover 31.

Therefore, the utility model discloses technical scheme's frying and roasting machine 100 is connected through the lid 31 with the pedestal 11 of base subassembly 10 and upper cover subassembly 30, makes lid 31 can open or the lid fits overware 13 to can realize getting of food or cook and heat food. And through rotatably setting overware 13 on base body 11, promptly, overware 13 can rotate relative lid 31 and base body 11, so make the in-process of heating food, the food in overware 13 can rotate relative to the heat source to make food be heated evenly, the effectual phenomenon of avoiding food to bake burnt.

Referring to fig. 3 to fig. 6, in order to realize the rotation of the baking tray 13, in an embodiment of the present application, the base assembly 10 includes a rotating member 15, the rotating member 15 is disposed in the base body 11, a positioning member 131 is disposed on one side of the baking tray 13 facing the base body 11, and when the rotating member 15 is driven, the rotating member can abut against and drive the positioning member 131, so that the baking tray 13 rotates relative to the base body 11.

In this embodiment, the rotating member 15 includes a connection column 151 and a contact block 153, one end of the connection column 151 is connected to the output end of the driving member 17, the other end of the connection column is connected to the contact block 153, the contact block 153 is disposed at an included angle with the connection column 151, and the contact block 153 is in contact with the positioning member 131. The positioning member 131 is located on one side of the baking tray 13 facing the bottom wall of the receiving cavity 11a and is formed into an integral structure with the bottom wall of the baking tray 13 to ensure good structural strength between the positioning member 131 and the baking tray 13. Driving piece 17 and rotating member 15 set up in the bottom that holds the chamber 11a, and the spliced pole 151 extends towards overware 13 after connecting driving piece 17, and from this when driving piece 17 drive spliced pole 151 rotates, spliced pole 151 drives the butt block 153 butt in setting element 131 to drive the overware 13 that sets up in holding the chamber 11a and rotate. It can be understood that in the embodiment, only the positioning member 131 and the rotating member 15 are in abutting transmission, so that a complex structure is not required to be arranged on the baking tray 13, thereby facilitating to simplify the structure of the baking tray 13 and ensuring the strength of the baking tray 13.

Further, as shown in fig. 5 and 6, in the direction in which the bakeware 13 rotates relative to the seat body 11, a gap is formed between the rotating member 15 and the positioning member 131, and the rotating member 15 can rotate in the gap.

Specifically, the gap is formed between the abutment block 153 of the rotary member 15 and the positioning member 131, and the size of the gap can be set adaptively according to actual conditions. Through setting up the clearance between rotating member 15 and setting element 131 for under the condition of placing more, heavier edible material on overware 13, driving piece 17 makes it have the buffering space of removal owing to the clearance between rotating member 15 and overware 13 when starting, can just carry out the butt through rotating member 15 to overware 13 that bears the great edible material and drive to normal work after starting. Therefore, the possibility that the driving part 17 is damaged due to the fact that more food materials are placed on the baking tray 13 when the driving part is started is reduced, and the driving part is blocked to generate heat, and normal and stable work of the cooking appliance is guaranteed.

In an embodiment of the present application, the number of the abutting blocks 153 is plural, and the plural abutting blocks 153 are distributed at intervals around the center line of the connecting column 151; the number of the positioning members 131 is multiple, the positioning members 131 are distributed at intervals around the center line of the baking tray 13, one abutting block 153 is arranged between every two adjacent positioning members 131, and the gap is formed between each abutting block 153 and the positioning member 131 adjacent to the abutting block 153.

It can be understood that the plurality of abutting blocks 153 and the plurality of positioning members 131 are arranged so that each portion of the baking tray 13 can be driven by the abutting cooperation of the plurality of abutting blocks 153 and the plurality of positioning members 131 in the rotation direction, thereby facilitating the rapid and stable driving of the baking tray 13 by the rotating member 15. Moreover, the arrangement is convenient for ensuring that the rotating piece 15 can abut against the positioning piece 131 when being driven, thereby being beneficial to ensuring the effectiveness of the rotating piece 15 in driving the baking tray 13. Meanwhile, the overall strength of the rotating part 15 is improved, and the possibility that the positioning part 131 is broken when the rotating part is abutted to the positioning part is reduced, so that the service life of the rotating part 15 is prolonged. In addition, the driving member 17 for driving the rotation member 15 to rotate may be a bidirectional synchronous motor, so that the abutment block 153 of the rotation member 15 may rotate in the opposite direction when the rotation in one direction is resisted by one of the two adjacent positioning members 131. When the baking tray 13 is installed in the accommodating cavity 11a, it is ensured that one abutting block 153 is inserted into two positioning members 131, and the placing angle of the baking tray 13 does not need to be adjusted along the circumferential direction. Of course, the driving member 17 may also be a unidirectional motor, and at this time, when the baking tray 13 is installed in the accommodating cavity 11a, after one abutting block 153 is inserted into two positioning members 131, the baking tray 13 is rotated along the opposite direction of the rotation direction of the driving member 17 until the abutting block 153 abuts against one positioning member 131 of the two positioning members 131, so that when the driving member 17 is started, the abutting block 153 can rotate between the two positioning members 131 to ensure the normal start of the driving member 17.

Referring to fig. 6, based on the above-mentioned embodiment, in the present application, the rotation angle α formed by the abutting block 153 rotating between two adjacent positioning members 131 is not less than 5 ° and not more than 80 °.

When the angle α is smaller than 5 °, the rotation gap between the two positioning members 131 of the abutting block 153 is small, which affects the movement buffering effect of the driving member 17 when being started. When the rotation angle α formed by the rotation of the abutting block 153 between two adjacent positioning members 131 is greater than 80 °, the rotation gap of the abutting block 153 between two positioning members 131 is large, so that the abutting block 153 abuts to and drives the positioning member 131 after rotating for a long time, thereby affecting the efficiency of driving the baking tray 13. Therefore, in order to achieve the buffering effect on the movement of the driving member 17 and the driving efficiency on the grill pan 13, the rotation angle α formed by the rotation of the abutting block 153 between the two adjacent positioning members 131 is set to 5 ° or more and 80 ° or less. The rotation angle α formed by the rotation of the abutting block 153 between two adjacent positioning members 131 may be 5 °, 10 °, 15 °, 20 °, 25 °, 30 °, 35 °, 40 °, 45 °, 50 °, 55 °, 60 °, 65 °, 70 °, 75 °, and 80 °, which may also be any value in the above interval.

With continued reference to fig. 3, in an embodiment of the present application, a space is formed between a surface of the abutting block 153 facing away from the connecting column 151 and a surface of the baking tray 13 provided with the positioning member 131.

Specifically, a supporting structure may be disposed between the tray bottom wall or the tray side wall of the baking tray 13 and the seat body 11, and the supporting structure is supported by the baking tray 13 in an abutting manner, so that the distance is formed between the surface of the abutting block 153 departing from the connecting column 151 and the surface of the baking tray 13 provided with the positioning piece 131. The arrangement is such that the rotary part 15 is not subjected to the pressing force of the grill pan 13, but only subjected to the resistance of the positioning part 131 in the circumferential direction during driving. The resistance to the rotation of the rotary member 15 driven by the driving member 17 is reduced, so that the possibility of the driving member 17 being locked due to the excessive force applied when the driving member 17 is started is further reduced. Meanwhile, the arrangement also reduces the possibility that the baking tray 13 transfers heat to the driving part 17 through the rotating part 15 after being heated, thereby being beneficial to improving the protection effect of the driving part 17.

Referring to fig. 3 and 4, further, in an embodiment of the present application, the base assembly 10 further includes a plurality of rolling members 19, the plurality of rolling members 19 are disposed at intervals along a circumferential direction of the base body 11, and the baking tray 13 abuts against the plurality of rolling members 19 and can be driven by the rotating member 15 to rotate.

The rolling members 19 may be rollers or balls, etc., a plurality of rolling members 19 may be embedded and fixed on the surface of the base 11 where the cavity 11a is formed, and the number of the rolling members 19 may be 3, 4 or more. Through the rolling member 19 that sets up for bakeware 13 is being driven by rotating member 15 and is carrying out the in-process of rotation, be rolling friction between bakeware 13 and the pedestal 11, so can reduce the frictional force that bakeware 13 received when rotating for pedestal 11, thereby be favorable to improving bakeware 13 pivoted smoothness nature, reduce wearing and tearing and be favorable to prolonging bakeware 13 and bearing structure's life at the rotation in-process simultaneously, and, through the setting of rolling member 19, the noise that can great reduction brought because bakeware 13 and pedestal 11 looks mutual friction.

The above description mainly describes the related embodiment of the relative rotation of the baking tray 13, and the following description will specifically describe the related contents of the heat dissipation air duct 310 in the cover 31.

Referring to fig. 2 and fig. 7, in an embodiment of the present application, the frying and baking machine 100 further includes an air exhausting device 35, wherein the air exhausting device 35 is disposed in the heat dissipating air duct 310 and drives air to enter through the air inlet aperture 3131 and to be exhausted through the air outlet aperture 3133. Wherein, the exhaust device 35 may be a fan, a blower, an induced draft fan, or the like, and the exhaust device 35 may be disposed near the air inlet 3131 or near the air outlet 3133. In order to allow the exhaust unit 35 to be stably installed, the exhaust unit 35 may be mounted on the inner wall of the cover 31 using a bracket. The air flow in the heat dissipation air duct 310 can be increased by the arrangement of the air exhausting device 35, so that heat transferred to the surface of the cover 31 can be rapidly taken away.

Further, referring to fig. 9, a handle 3111 is formed by extending an edge of one side of the cover 31, and the air inlet 3131 and the air outlet 3133 are symmetrically disposed on a side of the cover 31 away from the handle 3111. Specifically, the handle 3111 may be formed by extending an edge of the cover 31, and the opening and closing operations of the cover assembly 30 may be easily performed by the handle 3111. By disposing the air inlet 3131 and the air outlet 3133 away from the handle 3111, the user is not scalded by the hot air discharged from the heat dissipating air duct 310 during the operation of the handle 3111.

In the embodiment of the present application, the number of the air inlet holes 3131 is plural, and a plurality of the air inlet holes 3131 are arranged on the cover 31 to form an aperture array; and/or, the number of the outlet holes 3133 is plural, and the plurality of outlet holes 3133 are arranged on the cover 31 to form a hole array. In this embodiment, the air inlet holes 3131 and the air outlet holes 3133 are both micro-holes, and the air inlet holes 3131 and the air outlet holes 3133 both form a hole array on the cover 31, and the hole array may be circular or square. Therefore, the cover 31 is formed with a grid structure, which not only increases the air inlet amount and the air outlet amount of the heat dissipation air duct 310, but also prevents external foreign matters from entering the cover 31 through the air inlet holes 3131 or the air outlet holes 3133, thereby effectively preventing the heat dissipation air duct 310 from being blocked.

Further, in the present application, the height of the air inlet hole 3131 in the vertical direction of the opening in the cover 31 is higher than the height of the opening at the other end in the vertical direction; and/or, the height of the opening in the cover 31 at the air outlet 3133 is higher than that of the opening at the other end. So set up for be stained with in the liquid that attaches the lateral wall at the lid 31 can't get into the lid 31 through fresh air inlet 3131 or exhaust vent 3133, thereby improved the waterproof performance of frying and baking machine 100 greatly, avoid bringing the safety risk because of intaking.

Referring to fig. 8, based on the above-mentioned embodiment, an included angle β between a central line of the air inlet 3131 or the air outlet 3133 and a horizontal line satisfies a relationship: beta is more than or equal to 5 degrees and less than or equal to 45 degrees.

The included angle β should not be too large or too small. If the angle of the air inlet hole 3131 or the air outlet hole 3133 is too large, the air in the cover 31 is discharged through the air outlet hole 3133, or the corner of the air flow path is too large when external fresh air enters through the air inlet hole 3131, which is not favorable for smooth air circulation; if it is too small, the heights of the openings at both ends of the air inlet hole 3131 or the air outlet hole 3133 are relatively close, and the air inlet hole 3131 or the air outlet hole 3133 tends to be flat, so that external water or oil and the like easily enters the cover body 31 through the air inlet hole 3131 or the air outlet hole 3133. Increasing the risk of water ingress. Therefore, in the present embodiment, the angle β is set within a range of not less than 5 ° and not more than 45 °.

It can be understood that, in practical applications, the included angle β between the central line of the air inlet 3131 or the air outlet 3133 and the horizontal line may be specifically 5 °, 10 °, 15 °, 20 °, 30 °, 35 °, 40 °, or 45 °.

Referring to fig. 2, 7 and 10 in combination, in an embodiment of the present application, the upper heating element 331 is a light wave tube, which may be in a ring or ring-like structure, and the center of the light wave tube coincides with the center of the cover 31. It can understand ground, through setting up heating member 331 as the light-wave tube with last for the light wave heat source that is provided by the light-wave tube can produce high temperature high fever rapidly, and cooling speed is also very fast, and heating efficiency is higher, can not be to food scorching moreover, and then guaranteed food color and luster and taste. Of course, in other embodiments, the upper heating element 331 may also be a heating element such as an electric heating tube or an electric heating wire.

Referring to fig. 2, in order to enable most of the heat of the upper heating element 331 to be transmitted to the baking tray 13 for heating, in an embodiment of the present application, the upper cover assembly 30 further includes a reflective cover 333, the reflective cover 333 is connected to the cover 31 and encloses the heat dissipation air duct 310, and the upper heating element 331 is located on a side of the reflective cover 333 away from the heat dissipation air duct 310.

The reflective cover 333 may have a circular cover structure, and the reflective cover 333 may reflect heat of the upper heating member 331 and reflect the heat emitted outward to the grill pan 13 of the grill 100. Therefore, when the heat of the upper heating element 331 tries to be transmitted to the outside or the surface of the cover 31, most of the heat can be reflected by the reflective cover 333, and a small part of the heat passing through can be taken away by the air flow in the heat dissipation air duct 310, so that the heat utilization rate is improved, and the formation of high temperature and high heat on the surface of the cover 31 is avoided.

Further, the upper cover assembly 30 further includes a heat insulation cover 335, and the heat insulation cover 335 is connected to a side of the reflection cover 333 away from the upper heating element 331, and encloses with the reflection cover 333 and the cover 31 to form the heat dissipation air duct 310. The heat insulation cover 335 may also be a circular cover structure, and the diameter of the heat insulation cover 335 is smaller than that of the reflection cover 333, and the heat insulation cover 335 covers the outer wall of the reflection cover 333 and forms the heat dissipation air duct 310 together with the reflection cover 333 and the cover 31. It can be understood that, through the arrangement of the heat shield 335, the heat passing through the reflector 333 can be blocked, and therefore, the heat radiated outside can be prevented from passing through the reflector 333, the heat shield 335 and the heat dissipation air duct 310 in sequence to be blocked and ventilated and radiated, so that triple protection is formed, and the cover 31 is ensured not to generate high temperature.

Further, the upper cover assembly 30 further comprises a protection cover 337, the protection cover 337 is connected with the reflection cover 333 and encloses to form an installation cavity 339, and the upper heating element 331 is located in the installation cavity 339.

Specifically, the protection cover 337 may have a micro-porous plate structure with a plurality of micro-holes, which allows heat to pass through, and the protection cover 337 may be detachably fixed to the inner wall of the reflection cover 333 by means of clamping, fastening, or the like. Thus, by providing the protection cover 337, the heat of the upper heating member 331 in the installation cavity 339 can be normally transferred, and the user can be prevented from mistakenly touching the upper heating member 331.

Referring to fig. 2 again, in another embodiment of the present application, a buffer space 310a is formed between the side walls of the reflection cover 333 and the heat insulation cover 335 and the side wall 313 of the cover 31, an air passing space 310b is formed between the top wall of the reflection cover 333 and the heat insulation cover 335 and the top cover 311 of the cover 31, and the buffer space 310a and the air passing space 310b are communicated with each other and form the heat dissipation duct 310.

Specifically, in this embodiment, a buffer space 310a is formed in one or half turn between the side walls of the reflection cover 333 and the heat insulating cover 335 and the side wall plate 313, and the top is an overfire space 310 b. Therefore, in practical applications, after the air enters through the air inlet aperture 3131 on one side of the side wall plate 313, the air first reaches the buffer space 310a, and blows against the side walls of the reflective cover 333 and the heat insulation cover 335, then rises to a certain height, then flows through the air passing space 310b in a advection manner through the air passing space 310b, and then descends to the buffer space 310a on the other side, and is discharged through the corresponding air outlet aperture 3133. With such an arrangement, the heat dissipation air duct 310 forms a circuitous path in the cover 31, so that the area of the air contacting the reflective cover 333 and the heat shield 335 is large, the stay time in the cover 31 is long, and further, the heat in the cover 31 can be discharged more easily, and the cover 31 can be prevented from generating high temperature.

Further, in an embodiment of the frying and roasting machine 100 of the present application, the frying and roasting machine 100 further includes a buffering structure, and the buffering structure is disposed at least one of the base 11 and the upper cover assembly 30 and is configured to provide a buffering force when the upper cover assembly 30 opens or closes the roasting pan 13. That is, the buffering structure may be separately disposed on the upper cover assembly 30 or the seat body 11, or may be partially disposed on the upper cover assembly 30, and the other portion is disposed on the seat body 11. It should be noted that the buffering force provided by the buffering structure may be used to buffer the impact force when the upper cover assembly 30 and the seat body 11 are closed, or may be used to buffer the impact force after the upper cover assembly 30 and the seat body 11 are opened to a predetermined angle.

In this embodiment, through the design of the buffering structure, a buffering force is provided in the process of opening or closing the upper cover assembly 30 and the seat body 11 to buffer the impact force during opening or closing. Therefore, even under the condition that the weight of the upper cover assembly 30 is heavier, strong impact cannot be caused in the process of state change of opening or closing with the seat body 11, so that damage to the upper cover assembly 30 and the seat body 11 when opening or closing is effectively avoided, and safety accidents such as hand clamping and the like are avoided.

Referring to fig. 10 to 14, in an embodiment of the present application, the buffering structure is a damper 50, the upper cover assembly 30 includes a hinge shaft 36 fixedly connected to the cover 31, and the damper 50 is sleeved outside the hinge shaft 36 and connected to the seat 11, so that the cover 31 is turned over relative to the seat 11 to open or cover the base assembly 10.

In this embodiment, referring to fig. 13, the damper 50 may be a hydraulic damper, which includes a sleeve 51 and a shaft core 53 disposed in the sleeve 51, and a mounting portion 511 is formed on an outer wall of the sleeve 51, and is connected and fixed to the base assembly 10 through the mounting portion 511. The hinge shaft 36 is inserted into a shaft core 53 inside the sleeve 51, a partition plate 55 is arranged on the shaft core 53, the space inside the sleeve 51 is divided into two parts by the partition plate 55, and the liquid passing hole 551 communicating the two parts is opened on the partition plate 55, and the two parts are filled with hydraulic oil. Therefore, when the cover 31 is turned over relative to the base assembly 10, the hinge shaft 36 rotates along with the cover 31, and at this time, the hinge shaft 36 drives the shaft core 53 and the partition plate 55 on the shaft core 53 to rotate together, so that during the rotation of the partition plate 55, the partition plate 55 is also pushed back by the hydraulic oil while the hydraulic oil is squeezed, thereby forming a buffering effect. Of course, in other embodiments, the damper 50 may be an elastic damper or the like as is commonly used in the art. The damper 50 is used as a buffer structure, which can buffer the impact of the heavy upper cover assembly 30 and has high reliability.

In order to keep the hinge shaft 36 and the cover 31 relatively fixed, the upper cover assembly 30 further includes a fixing member 34, the cover 31 is provided with a mounting seat 315, the fixing member 34 is fixedly connected with the mounting seat 315, and the hinge shaft 36 is inserted and fixed to the fixing member 34. Specifically, the number of the mounting seat 315 and the fixing member 34 is two, the two ends of the hinge shaft 36 are respectively inserted and fixed to the fixing member 34, and are fixed to the mounting seat 315 through the fixing member 34, so that the hinge shaft 36 is stably mounted, and the assembling and disassembling operations are convenient.

Based on the above embodiment of the fixing member 34, in the present application, the fixing member 34 includes the barrel portion 341 and the positioning portion 343 disposed on the outer side wall of the barrel portion 341, the hinge shaft 36 is fixed to the barrel portion 341 in an inserting manner, the mounting seat 315 is provided with the limiting hole 3151, the hole wall of the limiting hole 3151 is concavely provided with the limiting groove 3153, and the barrel portion 341 is installed in the limiting hole 3151, and the positioning portion 343 is clamped in the limiting groove 3153.

In this embodiment, the barrel 341 and the positioning portion 343 are an integral structure, the number of the positioning portions 343 may be plural, the plural positioning portions 343 are arranged at intervals along the circumferential direction of the barrel 341, and the number of the limiting grooves 3153 is the same as the number of the positioning portions 343. In practical applications, when the cylindrical body 341 is inserted into the limiting hole 3151, the positioning portion 343 and the limiting groove 3153 cooperate with each other, so that the circumferential direction of the cylindrical body 341 is limited and the cylindrical body 341 is prevented from rotating in the limiting hole 3151, and therefore, after the hinge shaft 36 is inserted into the cylindrical body 341, the hinge shaft 36 and the cover 31 are prevented from rotating relatively.

Referring to fig. 12, in order to enable the hinge shaft 36 and the barrel 341 to be stably fixed in an inserting manner, in an embodiment of the present application, the outer wall of the hinge shaft 36 is provided with a first rotation stopping plane 361, and the inner wall of the barrel 341 is provided with a second rotation stopping plane 3411 attached to the first rotation stopping plane 361. Specifically, the end of the hinge shaft 36 may first pass through the mounting seat 315 and then extend into the limiting hole 3151, and then be fixed by interference fit with the barrel 341 in the limiting hole 3151, and meanwhile, the first rotation-stopping plane 361 on the hinge shaft 36 is attached to the second rotation-stopping plane 3411 on the inner wall of the barrel 341, so as to limit the circumference of the hinge shaft 36 and improve the stability of the installation of the hinge shaft 36.

Based on the above-mentioned embodiment of the damper 50, considering that the weight of the upper cover assembly 30 is heavy in some cases, a large impact force still exists after the damper 50 is used for buffering in the closing process, so that a large pressure is easily generated on the food on the baking tray 13, and the appearance and the taste of the food are affected. Therefore, in an embodiment of the present application, the upper cover assembly 30 further includes an elastic member 37, one end of the elastic member 37 is connected to the cover 31, and the other end is connected to the base assembly 10; when the elastic member 37 is in a natural state, the cover 31 opens the base assembly 10; when the cover 31 covers the base assembly 10, the elastic member 37 provides an elastic force to the cover 31 in a direction of opening the base assembly 10.

One end of the elastic piece 37 is connected with the upper cover body 31, the other end of the elastic piece is connected with the base assembly 10, when the upper cover assembly 30 covers towards the base assembly 10, the elastic piece 37 has elastic force deviating from the upper cover assembly 30 towards the base assembly 10 to the upper cover assembly 30, so that the elastic force can balance part of gravity of the upper cover assembly 30, the pressure of the upper cover assembly 30 on food placed on the baking tray 13 is reduced, and the original shape and good taste of the food can be better guaranteed.

Specifically, the elastic member 37 may be a spring or a leaf spring. When the elastic member 37 is a spring, the spring may be a telescopic spring or a torsion spring. For example, when the elastic member 37 is a retractable spring, one end of the retractable spring may be connected to the side of the cover 31 facing the base assembly 10, and the other end of the retractable spring may be connected to the side of the base assembly 10 facing the cover 31. When the cover 31 is in a state of opening the base assembly 10, the spring is compressed; when the cover 31 is shifted from the above-mentioned equilibrium state to the state of covering the base assembly 10, the spring is further compressed, and at this time, the elastic force of the spring to the cover 31 is increased, and when the cover 31 completely covers the base assembly 10, the pressure of the cover 31 to the food is smaller than its own gravity. Of course, in the technical solution of the present invention, the elastic member 37 can also be disposed on one side of the cover 31 departing from the base assembly 10, as long as the cover 31 covers the base assembly 10, the elastic member 37 has an elastic force on the cover 31 in the direction of opening the base assembly 10.

In an embodiment of the present application, the elastic member 37 is a torsion spring, and the torsion spring is sleeved outside the hinge shaft 36. In practical application, the two connecting ends of the torsion spring are respectively connected with the cover body 31 and the base assembly 10, and the torsion spring has torsion moment, so that the torsion spring can be pulled reversely when the cover body 31 is covered, and the torsion spring has good fatigue resistance and better reliability compared with other elastic parts 37 under the condition of having dynamic load.

According to the above-described embodiment, in order to prevent the torsion spring from wearing against the hinge shaft 36 during movement after being fitted around the hinge shaft 36. In this application the upper cover assembly 30 further includes a protection sleeve 38, the outer sidewall of the hinge shaft 36 is sleeved with the protection sleeve 38, and the torsion spring is sleeved outside the protection sleeve 38. Specifically, the protective sleeve 38 may be a plastic sleeve or a metal sleeve with high wear resistance and good fatigue resistance, the protective sleeve 38 is relatively fixed to the hinge shaft 36, and the blocking torsion spring is in direct contact with the hinge shaft 36 to form a protective effect.

In some other embodiments of the frying and roasting machine 100 of the present application, the buffering structure comprises a first magnetic member (not shown) and a second magnetic member (not shown), the first magnetic member is disposed on a side of the base assembly 10 covered with the upper cover assembly 30, the second magnetic member is disposed on a side of the upper cover assembly 30 covered with the base assembly 10 corresponding to the first magnetic member, and the first magnetic member and the second magnetic member repel each other magnetically.

The first magnetic member and the second magnetic member may be permanent magnets or electromagnets, and the magnetism of the first magnetic member and the magnetism of the second magnetic member repel each other. The first magnetic member may be embedded and fixed on a side of the base assembly 10 facing the cover assembly 30, and the second magnetic member may be embedded and fixed on a side of the cover assembly 30 facing the base assembly 10, and the positions of the first magnetic member and the second magnetic member correspond to each other. Therefore, when the upper cover assembly 30 covers the base assembly 10, the heavier upper cover assembly 30 can be buffered by repulsive force between the first magnetic member and the second magnetic member, and the upper cover assembly 30 is prevented from generating potential safety hazards due to strong impact.

Further, the first magnetic member is disposed at a position of the base assembly 10 away from the hinge-coupling with the upper cover assembly 30. I.e., the first and second magnetic members are positioned at a side away from the hinge shaft 36, it is understood that the arrangement is such that the repulsive force between the first and second magnetic members can provide better counterbalance to the heavier upper cover assembly 30 and is more designed in accordance with the principles of mechanics.

Referring to fig. 15, in an embodiment of the present application, the frying and baking machine 100 further includes a baffle 70, wherein the baffle 70 is connected to the base assembly 10 and shields a portion where the base assembly 10 is hinged to the upper cover assembly 30.
