Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of kitchen appliances, and particularly relates to a frying and baking machine. BACKGROUND

[0002] The frying and baking machine comprises an upper baking tray assembly and a lower baking tray assembly which are hingedly connected to each other, and the existing frying and baking machine usually has a control panel and an operation panel arranged on the lower baking tray assembly to facilitate the user to select and touch the cooking program. The upper baking tray assembly comprises an upper baking tray and a wire electrically connected to the upper baking tray, which needs to be led to the control panel of the lower baking tray assembly to realize the power supply and control of the upper baking tray.

[0003] During the test period before the frying and baking machine is shipped and the use process after the frying and baking machine is shipped, the upper baking tray assembly needs to be repeatedly flipped relative to the lower baking tray assembly many times. In order to reduce the abrasion of the wire electrically connected to the upper baking tray during repeated flipping, the existing frying and baking machine usually sets the leading position of the wire in the pivot shaft of the upper baking tray assembly and the lower baking tray assembly, so that the wire passes through the pivot shaft to move synchronously with the rotation of the pivot shaft.

[0004] However, with the increasing use requirements of users, the performance of the frying and baking machine is also continuously improved, and the upper baking tray assembly of the existing frying and baking machine can not only be partially flipped by less than or equal to 90° around the pivot shaft, but also can be further flipped to a flat state close to 180° to make the upper baking tray and the lower baking tray both have the function of carrying and frying food. In order to realize the large-angle opening and closing of the upper baking tray assembly, the pivot shaft of the upper baking tray assembly and the lower baking tray assembly of the existing frying and baking machine has the function of floating up and down in addition to the conventional rotation function, so that the pivot shaft can have pivot axes with different height positions when the upper baking tray assembly is flipped to different positions. When the height of the pivot axis changes, the wire passing through the pivot shaft will be pulled, especially the position of the axis port of the wire and the pivot shaft, which is easy to be abraded by the axis port of the pivot shaft during repeated pulling. The sharp straight edge of the axis port will cut the wire in contact with it during the pulling process, so that the wire is cut off and the frying and baking machine cannot be used normally. CONTENT OF THE UTILITY MODEL

[0005] The present application provides a frying and baking machine to solve the technical problem that the wire electrically connected to the upper baking tray assembly of the existing frying and baking machine is easy to be abraded and broken during the repeated opening and closing of the upper baking tray assembly.

[0006] The technical scheme adopted by the present application is as follows:

[0007] The application discloses a frying and baking machine, which comprises an upper baking tray assembly and a lower baking tray assembly, wherein the upper baking tray assembly and the lower baking tray assembly are pivotally connected through a hinging device, the hinging device comprises a hinging seat arranged on one of the upper baking tray assembly and the lower baking tray assembly, and a positioning cylinder arranged on the other one of the upper baking tray assembly and the lower baking tray assembly, the hinging seat is provided with a shaft hole, the positioning cylinder is arranged through the shaft hole and is provided with a first axis position and a second axis position, the upper baking tray assembly and the lower baking tray assembly are opened and closed around the positioning cylinder, the upper baking tray assembly is provided with a closed state, a side-standing state and a fully-opened state, the positioning cylinder is provided with a wire passing channel and a wire inlet and a wire outlet which are communicated with the wire passing channel respectively, a wire of the upper baking tray assembly passes through the wire passing channel and enters the lower baking tray assembly from the hinging seat, when the upper baking tray assembly is switched between the side-standing state and the fully-opened state, the positioning cylinder is switched between the first axis position and the second axis position of the shaft hole, the wire is provided with a tension state and a relaxation state according to the position switching of the positioning cylinder, and the positioning cylinder is provided with an anti-abrasion part at the wire inlet and / or the wire outlet.

[0008] The upper baking tray assembly in the application can be switched between the closed state, the side-standing state and the fully-opened state, and various use modes are provided to adapt to different cooking requirements and scenes. For example, in the closed state, full-speed cooking can be carried out to improve the cooking efficiency; for example, in the side-standing state, the user can conveniently turn over the food placed in the lower baking tray assembly or use the lower baking tray assembly alone for frying and baking operation without exerting force to hinder the downward turning and buckling of the upper baking tray assembly; for example, in the fully-opened state, the upper baking tray assembly and the lower baking tray assembly can be used to carry food materials respectively and work independently or simultaneously to realize personalized cooking. Through the switching of the positioning cylinder between the first axis position and the second axis position of the shaft hole, the accurate positioning of the upper baking tray assembly relative to the lower baking tray assembly is realized, which is helpful to maintain the stability and consistency in the cooking process.

[0009] The upper baking tray assembly is provided with a heating element for heating the upper baking tray, and part of the upper baking tray assembly of the fryer is also provided with a snap temperature controller for detecting the temperature of the upper baking tray. The electronic components such as the heating element and the snap temperature controller of the upper baking tray assembly need to be electrically connected to the control unit of the lower baking tray assembly through wires. The positioning cylinder in the present application is provided with a wire passing channel, and the wires pass through the wire passing channel to realize the lead wire from the upper baking tray assembly to the lower baking tray assembly. In this way, the abrasion of the wires caused by the rotation of the upper baking tray assembly relative to the lower baking tray assembly can be reduced. When the upper baking tray assembly is switched between the side standing state and the fully open state, the positioning cylinder is switched between the first axis position and the second axis position of the shaft hole. During the switching process, the wires are pulled and are close to the edge part of the wire inlet and the wire outlet of the positioning cylinder. The sharp straight edge of the edge part can cut the wires. The present application sets the wear-resistant pieces at the wire inlet and / or the wire outlet to protect the wires, reduce the abrasion of the wires caused by the edge part of the wire inlet and / or the wire outlet, and prolong the service life of the wires, thereby ensuring the stability and reliability of the working performance of the fryer.

[0010] The wear-resistant piece is a flange part outwardly folded from the wire inlet and / or the wire outlet.

[0011] The wear-resistant piece in the technical solution is a flange part arranged at the wire inlet and / or the wire outlet. By arranging the flange part, the sharp straight edge of the edge part of the wire inlet and / or the wire outlet can be changed into a relatively blunt flange structure to reduce the abrasion of the wires during the position switching of the positioning cylinder. The flange part is integrally formed with the positioning cylinder. On the one hand, the flange part can be more closely attached to the positioning cylinder to provide better protection for the wires and prolong the service life of the wires. On the other hand, the flange part can reduce additional welding or assembly steps, improve production efficiency, and shorten the production cycle.

[0012] The wear-resistant piece is a flange part outwardly folded from the wire inlet and / or the wire outlet, and the flange part is provided with at least one partition gap along the circumference of the wire inlet and / or the wire outlet.

[0013] The wear-resistant piece in the technical solution is a flange part arranged at the wire inlet and / or the wire outlet. By arranging the flange part, the sharp straight edge of the edge part of the wire inlet and / or the wire outlet can be changed into a relatively blunt flange structure to reduce the abrasion of the wires during the position switching of the positioning cylinder. The flange part is provided with at least one partition gap along the circumference of the wire inlet and / or the wire outlet, so that the flange part has a certain elastic property. In this way, when the wires are close to the flange part and are further passively pulled towards the flange part during the position switching of the positioning cylinder, a certain buffering effect can be achieved by the elasticity of the flange part, i.e. the hard friction and extrusion between the wires and the flange part are reduced, thereby reducing the cutting of the wires and prolonging the service life of the wires.

[0014] The connecting position between the flange part and the positioning cylinder is arc-shaped.

[0015] In the technical solution, the arc-shaped transition at the connecting position between the flange part and the positioning cylinder can provide a smooth curved path, making the wiring of the wire more smooth, reducing the wear caused by the angle mutation, and further improving the protection effect on the wire.

[0016] The folding angle of the flange part relative to the side wall of the positioning cylinder is greater than 90°.

[0017] In the technical solution, the folding angle of the flange part is greater than 90°, which means that the flange part forms an outwardly expanding arc surface at the connecting position with the positioning cylinder. This design can provide more space and protection for the wire, reduce the friction between the wire and the edge part of the inlet and / or outlet of the positioning cylinder, reduce wear, and prolong the service life of the wire.

[0018] The hinge seat is arranged on the lower baking tray assembly, the positioning cylinder is arranged on the upper baking tray assembly, the hinge seat is provided with a lead slot, and the inlet of the positioning cylinder extends into the lead slot.

[0019] In the technical solution, the hinge seat is arranged on the lower baking tray assembly, and the positioning cylinder is arranged on the upper baking tray assembly. The positioning cylinder can move with the upper baking tray assembly, and the positioning cylinder and the upper baking tray assembly remain relatively stationary. Therefore, during the state switching process of the upper baking tray assembly, the wire can move synchronously with the positioning cylinder, reducing the relative displacement between the positioning cylinder and the wire, thereby reducing the wear of the wire. The lead slot is arranged in the hinge seat, and the inlet of the positioning cylinder extends into the lead slot. When wiring, the wire inserted into the lead slot can directly enter the inlet of the positioning cylinder, thereby reducing the friction between the wire and the hinge seat and further reducing the wear of the wire during the state switching process of the upper baking tray assembly.

[0020] The wear-resistant part is a silica gel sleeve arranged on the inlet and / or outlet.

[0021] In the technical solution, the wear-resistant part is a silica gel sleeve arranged on the edge part of the inlet and / or outlet. Directly sleeving the silica gel sleeve on the edge part of the inlet and / or outlet of the positioning cylinder can reduce the processing difficulty of the positioning cylinder. The silica gel sleeve itself has elastic properties, which can realize flexible contact with the wire, improve the protection effect on the wire, and prolong the service life of the wire.

[0022] The shaft hole is provided with a guide sliding groove for switching the positioning cylinder between the first axis position and the second axis position.

[0023] The technical scheme sets a guide sliding groove in the shaft hole, which can provide accurate movement guidance for the positioning cylinder during position switching, so that the positioning cylinder can smoothly complete position switching, and the state switching of the upper baking tray assembly can be smoothly performed. Moreover, the guide sliding groove enables the position switching of the positioning cylinder to be completed within a preset displacement range, so that the relative displacement between the positioning cylinder and the wire is also within a preset range. By reasonably setting the position and structure of the wear-resistant part, the wear-resistant effect on the wire can be improved.

[0024] The wire is wrapped with a protective sleeve, and the protective sleeve extends at least through the wire passage.

[0025] The technical scheme wraps the wire with a protective sleeve, which can effectively protect the wire and reduce damage to the wire caused by friction, pulling or extrusion. Moreover, the protective sleeve can provide an additional insulation layer for the wire, which not only helps to provide better protection for the wire in humid or extreme temperature conditions, but also prevents the wire from being affected by dust, moisture, insects and other external environmental factors, thereby ensuring the reliability and stability of the electrical conductivity.

[0026] The upper baking tray assembly and / or the lower baking tray assembly is provided with a wire guide structure for guiding and limiting the wire.

[0027] The technical scheme sets a wire guide structure for guiding and limiting the wire on the upper baking tray assembly and / or the lower baking tray assembly. During the relative movement of the upper baking tray assembly and the lower baking tray assembly, the wire guide structure can prevent the wire from being disturbed greatly by the movement, which not only avoids interference or hooking of the wire with other parts in the upper baking tray assembly and / or the lower baking tray assembly, thereby disturbing the movement of the upper baking tray assembly, but also reduces the wear of the wire and prolongs the service life of the wire.

[0049] As Figures 1 to 5As shown, a grill machine includes an upper grill plate assembly 3 and a lower grill plate assembly 4, the upper grill plate assembly 3 and the lower grill plate assembly 4 are pivotally connected through a hinging device, the hinging device includes a hinging seat 2 provided on one of the upper grill plate assembly 3 and the lower grill plate assembly 4, and a positioning cylinder 1 provided on the other one of the upper grill plate assembly 3 and the lower grill plate assembly 4, the hinging seat 2 has a shaft hole 21, the positioning cylinder 1 is arranged through the shaft hole 21 and has a first axis position and a second axis position, the upper grill plate assembly 3 and the lower grill plate assembly 4 rotate to open and close around the positioning cylinder 1, so that the upper grill plate assembly 3 has a closed state, a side-standing state and a fully open state, when the upper grill plate assembly 3 switches between the side-standing state and the fully open state, the positioning cylinder 1 switches between the first axis position and the second axis position of the shaft hole 21, the positioning cylinder 1 is provided with a wire passing channel 13 and a wire inlet and a wire outlet respectively communicating with the wire passing channel 13, a wire of the upper grill plate assembly 3 enters the lower grill plate assembly 4 through the wire passing channel 13 from the hinging seat 2, when the upper grill plate assembly 3 switches between the side-standing state and the fully open state, the positioning cylinder 1 switches between the first axis position and the second axis position of the shaft hole 21, the wire has a tension state and a relaxation state with the position switching of the positioning cylinder 1, the positioning cylinder 1 is provided with an anti-wear part at the wire inlet and / or the wire outlet.

[0050] The upper grill plate assembly 3 in the present application can switch between the closed state, the side-standing state and the fully open state, providing multiple use modes to adapt to different cooking needs and scenes. For example, in the closed state, full-speed cooking can be performed to improve cooking efficiency; for example, in the side-standing state, the user can conveniently turn over the food placed in the lower grill plate assembly 4 or use the lower grill plate assembly 4 alone for grilling operation without applying force to hinder the downward turning and buckling of the upper grill plate assembly 3; for example, in the fully open state, the upper grill plate assembly 3 and the lower grill plate assembly 4 can be used to carry food materials respectively and work independently or simultaneously to realize personalized cooking. Through the switching of the positioning cylinder 1 between the first axis position and the second axis position of the shaft hole 21, the precise positioning of the upper grill plate assembly 3 relative to the lower grill plate assembly 4 is realized, which helps to maintain stability and consistency during cooking.

[0051] The upper baking tray assembly 3 is provided with a heating element for heating the upper baking tray, and part of the upper baking tray assembly 3 of the fryer is also provided with a snap temperature controller for detecting the temperature of the upper baking tray. The electronic components such as the heating element and the snap temperature controller of the upper baking tray assembly 3 need to be electrically connected to the control unit of the lower baking tray assembly 4 through wires. The positioning cylinder 1 in the present application is provided with a wire passing channel 13, and the wires are led from the upper baking tray assembly 3 to the lower baking tray assembly 4 through the wire passing channel 13. In this way, the abrasion of the wires caused by the rotation of the upper baking tray assembly 3 relative to the lower baking tray assembly 4 can be reduced. When the upper baking tray assembly 3 is switched between the side-standing state and the fully-open state, the positioning cylinder 1 is switched between the first axis position and the second axis position of the shaft hole 21. During this switching process, the wires are pulled and are close to the edge part of the wire inlet and the wire outlet of the positioning cylinder 1. The sharp straight edge of the edge part can cut the wires. The anti-abrasion piece arranged at the wire inlet and / or the wire outlet can protect the wires, reduce the abrasion of the wires caused by the edge part of the wire inlet and / or the wire outlet, and prolong the service life of the wires, thereby ensuring the stability and reliability of the working performance of the fryer.

[0052] The anti-abrasion piece in the present application can adopt any one of the following embodiments:

[0053] Embodiment one: as shown in Figure 6 and Figure 7 , the anti-abrasion piece is a flange part 11 folded outward from the wire inlet and / or the wire outlet, and the flange part 11 is integrally formed with the positioning cylinder 1. By arranging the flange part 11, the sharp straight edge of the edge part of the wire inlet and / or the wire outlet can be changed into a relatively blunt flange structure, so as to reduce the abrasion of the wires during the position switching of the positioning cylinder 1. The flange part 11 is integrally formed with the positioning cylinder 1, which can make the flange part 11 more closely adhere to the positioning cylinder 1, provide better protection effect for the wires, prolong the service life of the wires, and on the other hand, can reduce additional welding or assembly steps, improve production efficiency, and shorten production cycle.

[0054] As a preferred embodiment of the present embodiment, the connection position between the flange part 11 and the positioning cylinder 1 is arc-shaped. The arc-shaped transition at the connection position between the flange part 11 and the positioning cylinder 1 can provide a smooth curved path, so that the wires are more smooth when wiring, reduce the abrasion caused by the angle mutation, and further improve the protection effect of the wires.

[0055] In a preferred embodiment of this invention, the folding angle of the flanged portion 11 relative to the side wall of the positioning cylinder 1 is greater than 90°. A folding angle greater than 90° means that the flanged portion 11 forms an outwardly expanding arc surface at the connection point with the positioning cylinder 1. This design provides more space and protection for the wire, reduces friction between the wire and the edge of the inlet and / or outlet of the positioning cylinder 1, reduces wear, and extends the service life of the wire.

[0056] Implementation Method Two: (e.g.) Figure 8 As shown, the wear-resistant component is a flanged portion 11 that folds outward from the inlet and / or outlet. The flanged portion 11 has at least one partition gap 15 along the circumference of the inlet and / or outlet. In this embodiment, the wear-resistant component is a flanged portion 11 provided at the inlet and / or outlet. By providing the flanged portion 11, the sharp straight edge of the inlet and / or outlet can be transformed into a relatively blunt flanged structure, thereby reducing wear on the wires during the position switching of the positioning cylinder 1. The flanged portion 11 is provided with at least one partition gap 15 along the circumference of the inlet and / or outlet, so that the flanged portion 11 has a certain elasticity. This arrangement allows the flanged portion 11 to achieve a certain buffering effect when the wire is close to the flanged portion 11 and further passively pulled towards the flanged portion 11 during the position switching of the positioning cylinder 1. This reduces the hard friction and compression between the wire and the flanged portion 11, thereby reducing the cutting of the wire and extending the service life of the wire.

[0057] Furthermore, the positioning cylinder 1 is formed by winding a thin metal sheet, and the partition gap 15 is the gap between the first and last ends of the positioning cylinder 1 in the circumferential direction during the winding process. This setting can reduce the processing difficulty of the positioning cylinder 1.

[0058] As a preferred embodiment of this second implementation method, the width of the partition gap 15 is smaller than the outer diameter of the wire, so as to avoid the wire getting stuck in the partition gap 15 and causing a hard pull on the stuck wire during the movement of the upper baking pan assembly 3.

[0059] Implementation Method 3: The anti-wear component is a silicone sleeve fitted onto the inlet and / or outlet of the cable. In this implementation method, directly placing the silicone sleeve onto the edge of the inlet and / or outlet of the positioning cylinder 1 reduces the processing difficulty of the positioning cylinder 1. Utilizing the elastic properties of the silicone sleeve itself, flexible contact with the cable is achieved, improving the protective effect on the cable and extending its service life.

[0060] In this application, the hinge seat 2 and the positioning cylinder 1 can be positioned in any of the following embodiments:

[0061] Implementation Method 4: This implementation method 4 is not illustrated. In this implementation method 4, the hinge seat is located on the upper baking pan assembly, and the positioning cylinder is located on the lower baking pan assembly.

[0062] Implementation Method 5: (e.g.) Figures 1 to 5 As shown, the hinge seat 2 is located on the lower baking pan assembly 4, and the positioning cylinder 1 is located on the upper baking pan assembly 3. In this embodiment, by placing the hinge seat 2 on the lower baking pan assembly 4 and the positioning cylinder 1 on the upper baking pan assembly 3, the positioning cylinder 1 can move with the movement of the upper baking pan assembly 3. The positioning cylinder 1 and the upper baking pan assembly 3 remain relatively stationary. Thus, during the state switching process of the upper baking pan assembly 3, the wire can move synchronously with the movement of the positioning cylinder 1, reducing the relative displacement between the positioning cylinder 1 and the wire, thereby reducing wear on the wire.

[0063] As a preferred embodiment of this fifth implementation method, such as Figure 7 As shown, the hinge base 2 is provided with a lead wire groove 22, and the inlet of the positioning cylinder 1 extends into the lead wire groove 22. During wiring, the wire passing through the lead wire groove 22 can directly enter the inlet of the positioning cylinder 1, thereby reducing the friction between the wire and the hinge base 2, and further reducing the wear of the wire on the upper baking tray assembly 3 during state switching.

[0064] In a specific implementation, such as Figure 8 As shown, the positioning cylinder 1 includes a cylinder body 12, a wire passage 13, a wire inlet, and a wire outlet, all located within the cylinder body 12. The positioning cylinder 1 also includes a positioning part 14 connected to the cylinder body 12, and the positioning part 14 is fixedly connected to the upper baking tray assembly 3. Preferably, the positioning part 14 is detachably connected to the upper baking tray assembly 3 by means of screws, snap-fit, or other methods, to facilitate the disassembly and replacement of the positioning cylinder 1.

[0065] As a preferred embodiment of this application, such as Figure 2 and Figure 4 As shown, the shaft hole 21 is provided with a guide groove 211 for the positioning cylinder 1 to switch between the first axis position and the second axis position. By providing the guide groove 211 in the shaft hole 21, precise motion guidance can be provided for the positioning cylinder 1 during position switching, so that the positioning cylinder 1 can smoothly complete the position switching, thereby enabling the smooth switching of the upper baking tray assembly 3. Moreover, the presence of the guide groove 211 allows the position switching of the positioning cylinder 1 to be completed within a preset displacement range, so that the relative displacement between the positioning cylinder 1 and the wire is also within a preset range. By rationally setting the position and structural design of the anti-wear component, the anti-wear effect on the wire can be improved.

[0066] As a preferred embodiment of this application, such as Figure 9As shown, the wire is wrapped with a protective sleeve 5, and the protective sleeve 5 extends at least through the wire passage 13. By wrapping the wire with the protective sleeve 5, the wire can be effectively protected, and the damage to the wire caused by friction, pulling or extrusion can be reduced. Moreover, the protective sleeve 5 can provide an additional insulation layer for the wire, which not only helps to provide better protection for the wire under humid or extreme temperature conditions, but also can protect the wire from dust, moisture, insects and other external environmental factors, and ensure the reliability and stability of the electrical conductivity.

[0067] As a preferred embodiment of the present application, the upper baking tray assembly 3 and / or the lower baking tray assembly 4 is provided with a lead structure for guiding and limiting the wire. By providing the lead structure for guiding and limiting the wire in the upper baking tray assembly 3 and / or the lower baking tray assembly 4, the lead structure can avoid the wire from being disturbed greatly during the relative movement of the upper baking tray assembly 3 and the lower baking tray assembly 4, which not only avoids the wire from interfering with or being hooked on other parts in the upper baking tray assembly 3 and / or the lower baking tray assembly 4 to interfere with the movement of the upper baking tray assembly 3, but also reduces the wear of the wire and prolongs the service life of the wire.

[0069] Each embodiment in the present specification is described in a progressive manner, and the same or similar parts between each embodiment can be referred to each other, and each embodiment mainly describes the differences from other embodiments.
