[0051] like Figures 1 to 14As shown, the present application provides a safe grilling machine, including a grilling pan assembly, the grilling pan assembly includes a base 10 and a grilling pan 11 detachably mounted on the base 10, the grilling pan 11 is provided with a first coupler 12, a side of the grilling pan 11 facing the base 10 is provided with a heating pipe 14, the heating pipe 14 is connected to the first coupler 12, the grilling pan 11 includes a grilling pan body 111 and a first peripheral wall 112 arranged at the circumferential edge of the grilling pan body 111, the heating pipe 14 is arranged on the grilling pan body 111, the first peripheral wall 112 is provided with a mounting cavity 15, the first coupler 12 is installed in the mounting cavity 15 and is located on the outside of the heating pipe 14; the base 10 is provided with a second coupler 13, the circumferential edge of the base 10 is provided with a second peripheral wall 101, the second coupler 13 is arranged on the second peripheral wall 101, the first coupler 12 and the second coupler 13 are positioned correspondingly and are plug-fitted.

[0052] Specifically, Figure 2 and Figure 4 As shown, the grilling pan body 111 is in the shape of a disc, and the first coupler 12 is arranged on the first peripheral wall 112. The first coupler 12 and the heating tube 14 are not only arranged separately, but also arranged at different heights, which can greatly reduce the influence of the heat of the heating tube 14 on the first coupler 12. The first coupler 12 is arranged at the edge of the grilling pan 11. On the one hand, the first coupler 12 can be arranged away from the heating tube 14, which can avoid high temperature damage to the electrical components inside the first coupler 12, which is conducive to extending its service life. On the other hand, the first coupler 12 can be conveniently sealed with the help of the sealing member 181 on the handle 18, which provides favorable conditions for cleaning the grilling pan 11 and prevents water from entering the first coupler 12, so as to improve the safety of the product.

[0053] Among them, regarding the formation of the first circumferential wall 112, in one embodiment, the baking pan body 111 does not have a flange, and the first circumferential wall 112 is an upwardly extending annular wall structure arranged on the outer periphery of the baking pan body 111; in another embodiment, the baking pan includes a baking pan body 111 and a flange folded upward relative to the baking pan body 111. In this embodiment, the first circumferential wall 112 is arranged on the outer surface of the flange, so that the overall thickness of the flange plus the first circumferential wall 112 is increased, which is more conducive to the isolation of the first coupler 12 and the heating tube 14.

[0054] When the baking tray 11 is placed in the base 10, the second peripheral wall 101 surrounds the outside of the first peripheral wall 112, and the first coupler 12 and the second coupler 13 can be aligned and plugged. Both the first peripheral wall 112 and the second peripheral wall 101 are conducive to preventing heat from dissipating outward, thereby improving the utilization rate of heat energy.

[0055] The heat pipe 14 generally includes a heating section and a connecting end 141. The heating section is a heating area with a high temperature. The connecting end 141 is used to connect to an external circuit, etc., and the temperature of the connecting end 141 is low. In order to further reduce the influence of the heat of the heat pipe 14 on the first coupler 12, in a preferred embodiment, the connecting end 141 of the heat pipe 14 and the first coupler 12 are arranged on the same side, and the first coupler 12 is arranged opposite to the connecting end 141, or the first coupler 12 and the connecting end 141 are arranged in a staggered manner.

[0056] Since the temperature near the connection end 141 is relatively low, by arranging the first coupler 12 near the connection end 141 , the heat transfer from the heating zone of the heating tube 14 to the first coupler 12 can be further reduced, so that the first coupler 12 has a better working temperature and its reliability is improved.

[0057] Specifically, Figure 4 As shown, the first coupler 12 and the connection end 141 are, for example, arranged within the same semicircle. When the first coupler 12 is arranged opposite to the connection end 141, the heat of the high temperature zone of the heating tube 14 is difficult to radiate to the first coupler 12, thereby avoiding the temperature rise of the first coupler 12. When the first coupler 12 and the connection end 141 are arranged in a staggered manner, it may mean that the first coupler 12 is staggered with one of the two connection ends 141 (i.e., the radius from the center of the baking tray 11 to one of the connection ends 141 does not pass through the first coupler 12), or it may mean that the first coupler 12 is staggered with both connection ends 141.

[0058] As a preferred embodiment of the present application, a first opening 151 for installing the first coupler 12 is provided at the bottom of the installation cavity 15, and the end face where the first opening 151 is located is flush with the end face where the plug interface of the first coupler 12 is located or the end face where the first opening 151 is located is lower than the end face where the plug interface is located.

[0059] like Figure 1 As shown, taking the baking tray 11 as the lower baking tray, the installation cavity 15 surrounds the first coupler 12, and only the plug interface is exposed for plugging with the second coupler 13. The installation cavity 15 can form a waterproof structure to prevent daily external water from entering the first coupler 12 and causing safety accidents such as leakage. The depth of the installation cavity 15 is not less than the height of the first coupler 12 to improve the waterproof effect. When the first coupler 12 needs to be sealed, it is only necessary to close the first opening 151.

[0060] Furthermore, the baking pan body 111 is provided with a receiving groove 16, and the side wall of the receiving groove 16 facing the center of the baking pan 11 is provided with a through hole, and the connecting terminal of the heating tube 14 extends into the receiving groove 16 through the through hole, and the receiving groove 16 is provided with a second opening 161 facing the base 10. The baking pan assembly also includes a cover plate 17, and the cover plate 17 can be detachably installed on the second opening 161 for closing the second opening 161.

[0061] like Figure 4 As shown, the connection terminal of the heating tube 14 is arranged in the receiving groove 16 and covered by the cover plate 17. When cleaning the baking tray 11, it can prevent the cleaning water from entering the receiving groove 16 to cause short circuit and leakage at the electrical connection position, thereby improving the safety of product use. The heating tube 14 is distributed in a circular shape as a whole, so as to evenly heat the baking tray 11. The receiving groove 16 is arranged at the edge of one side of the baking tray body 111. Preferably, the receiving groove 16 is arranged close to the installation cavity 15 to facilitate the connection of the connection terminal with the first coupler 12.

[0062] In one embodiment, the receiving groove 16 is communicated with the installation cavity 15, and the first coupler 12 is provided with a wire 121, and the wire 121 is connected to the connection terminal. Specifically, one end of the wire 121 can be extended into the receiving groove 16 and connected to the connection terminal. When the baking tray 11 is installed in place, the first coupler 12 and the second coupler 13 are coupled and electrically connected, which can ensure that the heating tube 14 is powered on and works normally.

[0063] Further, such as Figure 4 As shown, a clamping groove 152 is provided on a side wall of the installation cavity 15 close to the receiving groove 16 to accommodate the wire 121 .

[0064] By providing the card slot 152 , the wire 121 can be arranged in a limited position, which can prevent the disorderly arrangement of the wire 121 from affecting the connection effect with the heating tube 14 , thereby ensuring the reliability of the electrical connection.

[0065] Furthermore, a third opening 162 is provided on one side of the accommodating groove 16 close to the mounting cavity 15, and the wire 121 extends into the accommodating groove 16 through the third opening 162. The cover plate 17 includes a main cover plate 171 that closes the second opening 161 and a side cover plate 172 that closes the third opening 162, and the side cover plate 172 is bent and connected to the main cover plate 171.

[0066] like Figure 2 and Figure 4As shown, the receiving groove 16 and the mounting cavity 15 are distributed in a stepped manner, and the third opening 162 extends from the baking pan body 111 to the peripheral wall 112. For this structure, the side cover plate 172 is bent downward relative to the main cover plate 171, so that the sealing effect of the cover plate 17 on the receiving groove 16 can be optimized. When cleaning the baking pan 11, the side cover plate 172 can prevent the cleaning water from entering the receiving groove 16 through the third opening 162 and flowing to the connection between the wire 121 and the connection terminal, making the waterproofing more reliable.

[0067] When cleaning the baking tray 11 , in order to prevent water from entering all electrical components, in addition to the above-mentioned cover plate 17 for waterproof protection of the receiving groove 16 , the present application also uses a seal 181 to seal the first coupler 12 .

[0068] As a preferred embodiment, the baking tray 11 is provided with a handle 18, and the handle 18 is provided with a seal 181. The handle 18 is rotatably connected to the outside of the mounting cavity 15 and has a first position and a second position. The bottom of the mounting cavity 15 is provided with a first opening 151 for installing the first coupler 12. When the handle 18 is in the first position, the first opening 151 is opened. When the handle 18 is in the second position, the seal 181 closes the first opening 151.

[0069] The present application sets the first coupler 12 at the edge of the baking tray 11, which can facilitate the rotation of the handle 18 so that the seal 181 can seal the first coupler 12. In this way, water can be prevented from entering the first coupler 12 when cleaning the baking tray 11, which can improve the safety of product use and help extend its life. Among them, the seal 181 on the handle 18 is used to seal the first coupler 12, and the additional sealing structure can be omitted, which is conducive to the simplification of the structure. At the same time, it can prevent the need to consider the storage problem of the sealing structure when using a separate sealing structure. If the storage is not appropriate, it may cause loss or difficulty in finding it in time. It is convenient for users to operate and can ensure effective sealing, which can improve the user experience. The handle 18 is rotatable, and its position can be adjusted to meet the requirements of plugging and using the first coupler 12 and sealing and waterproofing when cleaning the baking tray 11. The user only needs to operate the handle 18, which is simple and efficient.

[0070] like Figures 2 to 4 As shown, the sealing member 181 is disposed at the front end of the handle 18 , and the sealing member 181 is a blocking piece. When the handle 18 is located at the second position, the blocking piece covers the first opening 151 .

[0071] Preferably, the baffle is a high temperature resistant silicone sheet; then even if the baking tray 11 is at a high temperature right after use, the use of the baffle to seal the first coupler 12 can reduce the impact of the high temperature on the baffle, which is beneficial to extend its service life.

[0072] Furthermore, the front end surface of the baffle extends in an arc shape; setting the front end surface of the baffle into an arc shape is conducive to allowing the baffle to avoid the structure on the baking tray 11 during the rotation of the handle 18 to avoid interference, making the handle 18 rotate more smoothly and improving the rotation efficiency of the handle 18.

[0073] Furthermore, the cover plate 17 includes a connecting portion 173, the connecting portion 173 is provided with a first mounting hole 174, the handle 18 is provided with a connecting piece 182, the handle 18 is rotatably connected to one end of the connecting piece 182, the other end of the connecting piece 182 is provided with a second mounting hole 183, the outer wall of the mounting cavity 15 is provided with a mounting column 153, the baking tray assembly is provided with a fastener, and the fastener passes through the first mounting hole 174 and the second mounting hole 183 and is fastened in the mounting column 153.

[0074] like Figure 4 As shown, the connecting portion 173 is a rectangular frame, which can be adapted to fit the first opening 151 of the mounting cavity 15, and the connecting member 182 has a U-shaped or rectangular connecting bracket to fit the first opening 151 and the connecting portion 173. During specific installation, the connecting member 182 can be first fitted to the first opening 151 so that the second mounting hole 183 is aligned with the mounting column 153, and then the cover plate 17 is covered so that the first mounting hole 174 is aligned with the second mounting hole 183, and then the screws are inserted. Of course, the installation sequence is not limited to the above method, and the cover plate 17 can be placed first, and then the connecting member 182 is placed, and then the screws are inserted, which can be adjusted according to actual needs. The present application uses the same fastener to fix the cover plate 17 and the handle 18 on the baking tray 11, which has a compact structure and simple assembly, which is conducive to the simplification and miniaturization of the structure of the baking tray 11.

[0075] Furthermore, a handle 18 is provided on one side of the baking tray 11, and the handle 18 rotates relative to the baking tray 11 to have an unfolded position and a folded position. In the unfolded position, the seal 181 seals the first coupler 12, and in the folded position, the first coupler 12 is exposed from the seal 181.

[0076] like Figure 6 and Figure 7 As shown, the handle 18 can rotate in the plane where the baking tray 11 is located to have Figure 6 Folded position shown and Figure 7As shown in the unfolded position, when in the folded position, the distal end of the handle 18 is close to the center of the baking tray 11. At this time, the radial dimension of the overall structure formed by the baking tray 11 and the handle 18 is small. When the baking tray 11 is in the process of making food, it is not easy for the user to touch the handle 18, which can prevent the user from being scalded by the high temperature of the handle 18 (the baking tray 11 will inevitably transfer part of the heat to the handle 18 during operation); further, after using the baking tray 11, when the user needs to clean the baking tray 11, the user first adjusts the handle 18 to the unfolded position, at which time the distal end of the handle 18 is away from the center of the baking tray 11, and the first coupler 12 is sealed by using the sealing member 181. After sealing, the user holds the handle 18 to remove the baking tray 11 for cleaning (such as directly placing it under the faucet for rinsing), which provides cleaning convenience for the user.

[0077] Regarding the position of the handle 18, assuming Figure 6 The middle handle 18 is in the folded position at 0°. The handle 18 can be rotated 90° in the counterclockwise direction to reach Figure 7 The handle 18 can be further rotated 90° in the counterclockwise direction to reach another folded position, that is, the handle 18 can be rotated in the range of 0°ˉ180°, preferably with the above three positions. Of course, the handle 18 can also be adjusted to a position corresponding to any angle between 0°ˉ180°, and can be flexibly adjusted according to actual usage requirements.

[0078] Regarding the sealing member 181, it may be an independent structural member or may be attached to other structures. This application does not make any specific limitation. For example, any of the following methods may be adopted.

[0079] Implementation method 1:

[0080] The seal 181 is fixedly connected to the front end of the handle 18 , and rotates with the handle 18 , so that the seal 181 seals the first coupler 12 when in the unfolded position, and releases the seal on the first coupler 12 when in the folded position.

[0081] The seal 181 and the handle 18 can form a structural component, so that the seal 181 can rotate with the handle 18 to adjust its state. The user only needs to operate the handle 18 to adjust the state of the first coupler 12 (closed or open), and there is no need to perform separate sealing and unsealing steps, which can save user operations and improve the user experience; and setting the seal 181 on the handle 18 can reduce the number of assembly parts, simplify the structural configuration, and promote a compact layout of the structure. It can prevent the seal 181 from being lost and affecting the sealing of the first coupler 12, thereby ensuring the reliability of the sealing of the first coupler 12 and providing safety protection for users when cleaning the baking tray.

[0082] Specifically, the connection relationship between the seal 181 and the handle 18 can be that the seal 181 and the handle 18 are separate structures, and the two can be connected together by means such as screw connection, snap connection, bonding, etc. to form a structural part (that is, the two are already connected when they are delivered to the user from the factory, and the user does not need to install them by himself); or, the seal 181 and the handle 18 can be connected together by injection molding during processing to form a structural part; or, the seal 181 and the handle 18 can be integrally formed by double-material injection molding during processing (the seal 181 can be made of materials such as silicone, and the handle 18 can be made of materials such as plastic). Therefore, the seal 181 and the handle 18 are used as a structural part, which not only saves installation, but also enables the handle 18 to have both the function of a handle and the function of sealing, enriching the function of the accessory.

[0083] like Figures 8 to 10 As shown, the seal 181 can follow the rotation of the handle 18 to have different positions, for example, the handle 18 is in Figure 8 When the handle 18 is in the folded position, the seal 181 is located outside the first coupler 12, and the coupling terminal 123 in the first coupler 12 is exposed, which does not affect the cooperation between the first coupler 12 and the second coupler; when the handle 18 is in the Fig. 9 When the seal 181 is in the expanded position, it can extend into the first coupler 12 and shield the coupling terminal 123 inside, so that when the user washes the baking tray 11, the washing water cannot flow into the first coupler 12.

[0084] For example, Fig.10 As shown, the first coupler 12 is provided with a mounting portion 1211, the handle 18 includes a rotating portion 184 and a handle 185, the rotating portion 184 rotates around the mounting portion 1211 to drive the handle 185 to rotate, the sealing member 181 is protruded on the side of the rotating portion 184 facing away from the handle 185, the first coupler 12 includes a slot 122 and a coupling terminal 123 provided in the slot 122, and the rotating portion 184 rotates to drive the sealing member 181 to be inserted into and removed from the slot 122.

[0085] Specifically, Fig.10 As shown, the mounting portion 1211 is, for example, a boss extending from the upper end of the first coupler 12 toward the handle 18, and the boss is provided with a mounting hole 124. The rotating portion 184 includes a rotating shaft 186, and the rotating shaft 186 can rotate around the central axis of the mounting hole 124, as shown in FIG. Fig.10As shown, the rotating portion 184 is L-shaped, and its vertical rotating shaft 186 extends into the mounting hole 124, and its horizontal extension section is connected to the handle 185. Further, in order to achieve the fixation of the handle 18 and the mounting portion 1211, in one example, the rotating shaft 186 is a hollow rotating shaft 186, and a fastener such as a screw can penetrate into the rotating shaft 186 from above the mounting hole 124 and be threadedly locked with the rotating shaft 186. In another example, the upper end of the rotating shaft 186 passes through the mounting hole 124 and a buckle is provided at the end of the rotating shaft 186, which can prevent the rotating shaft 186 from escaping from the mounting hole 124, thereby achieving fixation.

[0086] Further, such as Fig.10 and Fig.11 As shown, the first coupler 12 is provided with a slot 122 located below the mounting portion 1211. The slot 122 extends horizontally, for example. When the handle 18 is in the folded position, the seal 181 moves out of the slot 122 and is located on the outside of the slot 122. When the handle 18 is in the unfolded position, the seal 181 can be horizontally inserted into the slot 122 to achieve sealing of the first coupler 12.

[0087] The sealing member 181 is interference fit with the slot 122 . Preferably, the thickness of the sealing member 181 is slightly greater than the thickness of the slot 122 , so as to ensure the sealing performance.

[0088] The specific structure of the seal 181 may be any of the following. In one embodiment, the seal 181 is an elastic insert, and an insert made of elastic material is directly used. When the insert is inserted into the slot 122, it can achieve sealing with the slot 122 by deformation. The structure is simple, the cost is low, and the sealing is reliable. In another embodiment, the seal 181 includes a support sheet and a sealing sleeve coated on the outer surface of the support sheet. The material of the support sheet can be plastic, metal, etc., which is not required in this application. The sealing sleeve is a silicone sleeve or a rubber sleeve, which can fill the matching gap between the support sheet and the slot 122 to achieve sealing. The sealing sleeve is a detachable structure so that it can be replaced when it is worn or deformed and fails. The maintenance cost is low, which is conducive to extending the service life of the accessories.

[0089] Furthermore, the slot 122 is provided with a fourth opening 125 toward the rotating portion 184, and the coupling terminal 123 extends toward the fourth opening 125. Two coupling terminals 123 are provided, which are respectively connected to the two lead-out ends of the heating tube 14. Correspondingly, the second coupler is provided with a plug hole for the coupling terminal 123 to be plugged in. When the seal 181 is inserted into the slot 122 and in place, the relationship between the seal 181 and the coupling terminal 123 may include the following: (1) The length of the seal 181 is less than the length of the slot 122, and a gap is formed between the seal 181 and the coupling terminal 123; (2) The length of the seal 181 is less than or equal to the length of the slot 122, and the seal 181 is provided with a lateral opening receiving groove, the upper surface of the seal 181 can be in close contact with the inner top wall of the slot 122, and the lower surface of the seal 181 is in close contact with the inner bottom wall of the slot 122, and the receiving groove provides an escape space for the coupling terminal 123, and the coupling terminal 123 can extend into the receiving groove.

[0090] Further, regarding the shape of the seal 181, in a preferred embodiment, the seal 181 is provided with a guide slope 1811, and the slot 122 is provided with a matching slope 1221 that matches the guide slope 1811. The guide slope 1811 can provide guidance for the seal 181 to be inserted into the slot 122, which can speed up the insertion of the seal 181 into the slot 122, improve efficiency, and ensure the reliability of the seal.

[0091] Specifically, the setting methods of the guide bevel 1811 may include the following: (1) the upper surface of the seal 181 is provided with a guide bevel 1811, and along the insertion direction of the seal 181, the guide bevel 1811 gradually tilts downward, and the lower surface of the seal 181 extends horizontally; (2) the upper surface of the seal 181 extends horizontally, and the lower surface of the seal 181 is provided with a guide bevel 1811, and along the insertion direction of the seal 181, the guide bevel 1811 gradually tilts upward; (3) the upper and lower surfaces of the seal 181 are both provided with guide bevels 1811, and along the insertion direction of the seal 181, the upper guide bevel 1811 gradually tilts downward, and the lower guide bevel 1811 gradually tilts upward.

[0092] For the above three methods, the longitudinal section of the sealing member 181 is trapezoidal. For example, for the above method (3), Fig.11 As shown, the longitudinal section of the sealing member 181 is an isosceles trapezoid, and the front end of the sealing member 181 is thinner, which is more conducive to rapid insertion into the slot 122 .

[0093] It can be understood that, unlike the above-mentioned embodiment, in other embodiments, the thickness of the sealing member 181 can be uniformly set, and in this case, the longitudinal section of the sealing member 181 is rectangular.

[0094] Further, such as Figure 8As shown, the front end of the seal 181 is configured to be arc-shaped, so that the seal 181 can avoid friction with the outer end surface of the first coupler 12 during rotation, thereby ensuring smooth rotation.

[0095] Implementation method 2:

[0096] The seal 181 is independent of the handle 18 and includes a hand-held portion 187 and a sealing portion 188 . The sealing portion 188 is used to seal the first coupler 12 . The outer diameter of the hand-held portion 187 is larger than the outer diameter of the sealing portion 188 to cover the outer end surface of the first coupler 12 .

[0097] Different from the above-mentioned first embodiment, the seal 181 is an independent accessory here, which can also adjust the state of the first coupler 12 to close or open the first coupler 12, thereby protecting the first coupler 12. In this embodiment, if the handle 18 is detachably connected to the baking tray 11, when the first coupler 12 needs to be sealed, the handle 18 can be removed first, and then the seal 181 can be installed, which can make the installation of the seal 181 more convenient and smooth. After the handle 18 is removed, the baking tray 11 can be placed in a dishwasher or other machine for automatic cleaning, without worrying about water entering the first coupler 12, which can reduce the burden on the user. Of course, if the handle 18 is not removable, it will not affect the disassembly and assembly of the seal 181. Specifically, when the handle 18 is in the unfolded position, there is a residual space between the handle 18 and the first coupler 12, which can allow the seal 181 to be inserted into the slot 122 of the first coupler 12. Furthermore, after the baking tray 11 is cleaned, the seal 181 can be removed. After the baking tray 11 is installed, the handle 18 can be adjusted to the folded position to facilitate subsequent machine operation.

[0098] like Fig.12 As shown, the sealing member 181 is T-shaped as a whole, the sealing portion 188 is a plug structure matched with the slot 122, and the hand-held portion 187 is a small-sized handle for easy user handling. Preferably, the width of the hand-held portion 187 is greater than the width of the sealing portion 188, and the hand-held portion 187 can completely cover the fourth opening 125 of the slot 122, thereby preventing the cleaning water from entering the slot 122.

[0099] On the basis of all the above implementations and examples, further, the first coupler 12 further includes a ground terminal 126, and the length of the ground terminal 126 is greater than the length of the coupling terminal 123. Figure 8 As shown, the grounding terminal 126 is arranged between the two coupling terminals 123. The end of the grounding terminal 126 away from the center of the baking tray 11 is closer to the outside than the end of the coupling terminal 123 away from the center of the baking tray 11. When the first coupler 12 is plugged in, it can be grounded first through the grounding terminal 126, and when the coupling is released, the grounding terminal 126 is detached last, which can ensure the safety of the machine operation and meet the safety regulations.

[0100] As a preferred implementation, the heating tube 14 and the baking tray 11 are cast into one piece by a casting material 19 , and the casting material 19 covers the heating tube 14 .

[0101] The casting material 19 is used to hide the heating tube 14, which can not only improve the aesthetics, but also improve the safety of cleaning the baking tray 11, making it more convenient to clean the baking tray 11, and the user does not need to worry about the safety issues in subsequent use, which is conducive to improving the user experience.

[0102] like Fig.13 and Fig.14 As shown, the heating tube 14 and the baking tray 11 are processed into an integrated structure through a casting process, which can improve the appearance and safety of the baking tray 11. Fig.13 As shown, the casting material 19 is a closed structure covering the heating tube 14, and the outer edge of the casting material 19 is not less than 5 mm away from the heating tube 14. It can be understood that due to the addition of the casting material 19, the preheating time will be increased when the baking tray 11 is heated. In order to shorten the preheating time and increase the preheating rate, the coverage area of ​​the casting material 19 can be reduced, such as Fig.14 As shown, in another embodiment, the casting material 19 is an annular structure covering the heating tube 14 , and the inner circle edge and the outer circle edge of the casting material 19 are not less than 3 mm away from the heating tube 14 .
