Description

Technical Field

[0001] The present invention relates to the field of ovens, and particularly to an oven with an anti-fool and anti-oil shield structure. Background Art

[0002] In recent years, with the progress of technology, new technologies such as vertical rotary ovens, intelligent control systems, and energy-saving heating devices have been successively applied to the design and transformation of ovens, significantly improving the heating effect and energy utilization efficiency.

[0003] There is a vertical barbecue oven with the authorized announcement number CN201451157U on the Chinese Patent Network. The vertical barbecue oven includes a box body and a base. The front of the box body is open, and the back of the box body is provided with a main gas inlet pipe. A number of gas combustion trays are arranged inside the box body. The gas combustion trays are disc-shaped with the opening facing forward. The opening of the gas combustion tray is hermetically covered with a ceramic plate facing the opening of the box body. The ceramic plate and the inner wall of the gas combustion tray enclose a combustion chamber. The main gas inlet pipe is communicated with a number of gas inlet branch pipes corresponding to each combustion chamber. The end of each gas inlet branch pipe is connected to a nozzle for introducing gas into the combustion chamber. It also includes an ignition needle installed on the box body, and the ignition head of the ignition needle is located inside the combustion chamber. A grease tray is arranged on the base. A rotating shaft located in front of the box body is arranged in the middle of the grease tray, and a barbecue rod stands upright above the rotating shaft.

[0004] However, when using the movement of the barbecue rod to replace the movement of the heat source, a trough-shaped opening for the movement of the barbecue rod must be provided on the grease tray. But this will cause another problem, that is, if there is no oil shield to prevent oil leakage from the trough-shaped opening, or if the assembly of the oil shield is forgotten when installing the barbecue rod, oil will leak from the trough-shaped opening into the interior of the device, contaminating components such as motors, making them difficult to clean and reducing their service life. Summary of the Invention

[0005] In view of this, the present invention provides an oven with an anti-fool and anti-oil shield structure to solve the above problems.

[0006] The oven with an anti-fooling and oil-proof cover structure includes an oven main body, an oil-proof cover disposed on the oven main body, and an anti-fooling mechanism disposed below the oil-proof cover. The oven main body includes an oil storage tray, a mounting frame disposed below the oil storage tray, and a barbecue rod assembly plugged into a motor assembly. A chute is provided in the middle of the oil storage tray, and a chute flange is provided on the outer periphery of the chute. The chute flange protrudes on a side facing away from the housing. The mounting frame is provided with a first mounting hole for plugging the barbecue rod assembly and a second mounting hole for mounting the anti-fooling mechanism. The barbecue rod assembly includes a barbecue rod and a connecting member fixedly provided on the barbecue rod. The oil-proof cover covers the outside of the chute flange. The anti-fooling mechanism includes a plug assembly fixedly connected to the oil-proof cover and a torsion spring shielding assembly disposed on a side of the mounting frame facing the plug assembly. The plug assembly includes a mounting plate fixedly connected to the oil-proof cover and a plug fixedly provided on a side of the mounting plate facing the torsion spring shielding assembly. The plug corresponds to the second mounting hole and is inserted into the second mounting hole when the oil-proof cover covers the chute flange. The plug includes a guiding surface provided at the end of the plug, and the guiding surface is inclined from small to large starting from the end of the plug. The tip of the plug corresponds to the gap between the second mounting hole and the torsion spring shielding assembly, and when the plug is not inserted into the second mounting hole, the shielding plate covers the first mounting hole. When the oil-proof cover is mounted on the chute flange, the plug is inserted into the second mounting hole, and the shielding plate is pushed by the plug. At this time, the shielding plate covering the first mounting hole moves to expose the first mounting hole, so that the connecting member can be inserted into the first mounting hole. The torsion spring assembly is used to provide a restoring force for the shielding plate. When the plug is pulled out from the second mounting hole, the shielding plate covers the first and second mounting holes again.

[0007] Further, the oven main body includes a housing, two oil draining plates disposed on the oil storage tray, and a motor assembly disposed in the mounting frame. The oil storage tray is fixedly provided on the housing. A circle of oil retaining flanges is provided at the edge of the oil storage tray. A second chute is provided at the joint of the two oil draining plates, and the second chute corresponds to the chute. Support flanges are provided on a side of the two oil draining plates facing the oil storage tray, and the support flanges are in contact with the edge portion of the oil storage tray.

[0008] Further, the mounting frame is fixedly arranged inside the housing and bears the motor assembly. The motor assembly includes a motor fixedly arranged on the mounting frame and a cross-shaped output head fixedly connected to the barbecue rod assembly. The connecting piece sequentially passes through the second chute, the oil-proof cover, the chute, the anti-fooling mechanism, and the first mounting hole, and finally is inserted into the motor. The connecting piece is connected to the cross-shaped output head, and a plugging groove is formed in the connecting piece.

[0009] Further, the anti-fooling mechanism includes an auxiliary mounting plate arranged between the oil storage pan and the mounting frame. The auxiliary mounting plate is fixedly arranged on the mounting frame, and a barbecue rod assembly guiding cylinder and a plug guiding cylinder are arranged thereon. The barbecue rod guiding cylinder corresponds to the first mounting hole, and the plug guiding cylinder corresponds to the second mounting hole.

[0010] Further, the plug further includes a clamping groove arranged above the guiding surface. The clamping groove is arranged on the plug and is clamped with the torsion spring shielding assembly.

[0011] Further, the torsion spring assembly includes a torsion spring arranged on the shielding plate, a connecting rod arranged at one end of the torsion spring, a fixing rod arranged at the other end of the torsion spring, and a rotating screw arranged in the middle of the torsion spring. The connecting rod is only fixedly arranged on the shielding plate, the fixing rod is only fixedly arranged on the mounting frame, the rotating screw fixes the torsion spring on the shielding plate and the mounting frame, and the free end of the torsion spring, i.e., the end where the connecting rod is located, is rotatably arranged on the mounting frame.

[0012] Further, the torsion spring assembly further includes a limiting rod arranged beside the plug and a sliding groove arranged on the shielding plate. The limiting rod is fixedly arranged on the mounting frame and is located in the sliding groove. When the shielding plate moves, the limiting rod moves relative to the shielding plate.

[0013] Further, the torsion spring shielding assembly includes a semi-shielding hole arranged on the shielding plate. When the oil-proof cover is mounted on the chute flange, the plug is inserted into the second mounting hole and pushes the shielding plate, and the semi-shielding hole exposes the first mounting hole as the shielding plate moves.

[0014] Further, the torsion spring shielding assembly further includes a roller corresponding to the plug. The roller is arranged at the edge of the shielding plate, and the gap between the roller and the second mounting hole corresponds to the end of the plug.

[0015] Compared with the prior art, the oven with an anti-fooling and anti-oil shield structure provided by the present invention sets the anti-fooling mechanism to achieve the anti-fooling function that the barbecue rod assembly cannot be installed without installing the anti-oil shield, thereby avoiding the omission of installing the anti-oil shield, and further avoiding the oil stain leaking onto the motor assembly and contaminating the motor assembly. The anti-fooling mechanism sets the baffle plate and the torsion spring assembly, so that when the bolt is not inserted into the second installation hole, the baffle plate covers the first and second installation holes. When the anti-oil shield is placed on the chute flange, the bolt fixedly arranged on the anti-oil shield passes through the chute and the bolt guiding cylinder and finally inserts into the second installation hole. At the same time, the bolt pushes the baffle plate, so that the first installation hole is exposed, and thus the connecting piece can be inserted. Through the anti-fooling mechanism, it can be ensured that only after the anti-oil shield is assembled can the barbecue rod assembly be assembled, thereby achieving the purpose of avoiding the omission of installing the anti-oil shield, and further ensuring the normal service life of the oven.

[0025] The following further elaborates on the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0026] The terms used herein are intended to explain the embodiments and are not intended to limit and / or define the present invention. It should be understood that the orientation or positional relationships indicated by the terms "front", "rear", "left", "right", "upper", "lower", etc. are based on the orientation or positional relationships shown in the drawings, or the orientation or positional relationships when the product of the present invention is in its usual placement, or the orientation or positional relationships commonly understood by those skilled in the art. These are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0027] Refer to Figures 1 to 9 , which is the structural schematic diagram of the oven with the anti-fool and anti-oil shield structure provided by the present invention. The oven with the anti-fool and anti-oil shield structure includes an oven main body 10, an oil shield 20 disposed on the oven main body 10, and an anti-fool mechanism 30 disposed below the oil shield 20. It can be conceived that the oven with the anti-fool and anti-oil shield structure further includes some other functional modules, such as a combustion furnace, a guide rail device, etc., which are well-known technologies to those skilled in the art and will not be elaborated herein.

[0028] The oven main body 10 includes a housing 11, an oil storage pan 12 fixedly installed on the housing 11, two oil draining plates 13 disposed on the oil storage pan 12, an installation frame 14 disposed below the oil storage pan 12, a motor assembly 15 disposed in the installation frame 14, and a meat roasting rod assembly 16 plugged into the motor assembly 15.

[0029] The housing 11 is a frame body with an opening on one side, which is used to carry and accommodate the above-mentioned various functional components and protect them.

[0030] The oil storage pan 12 is fixedly disposed on the housing 11, and its shape can be set according to actual needs. Such as Figure 8As shown, a ring of oil retaining flanges is provided at the edge of the oil storage tray 12, and a chute 121 is provided in the middle. The chute 121 is the space left for the front and back movement of the barbecue rod assembly 16. By adjusting the distance between the barbecue rod assembly 16 and the heat source, the doneness of the barbecue is controlled. A chute flange 122 is provided on the outer periphery of the chute 121. The chute flange 122 protrudes on the side facing away from the mounting frame 14. The chute flange 122 is used to support the oil-proof cover 20 and at the same time prevent the oil in the oil storage tray 12 from flowing down through the chute 121 to contaminate the motor assembly 15. Of course, it can be imagined that an oil guide pipe can also be provided on the oil storage tray 12, and the oil guide pipe can guide the oil in the oil storage tray 12 to the outside to avoid overflow of the oil in the oil storage tray 12.

[0031] A second chute 131 is provided at the joint of the two oil draining plates 13. The second chute 131 is arranged corresponding to the chute 121 and is the space left for the front and back movement of the barbecue rod assembly 16. On the side of the two oil draining plates 13 facing the oil storage tray 12, there are support flanges. The support flanges are attached to the edge part of the oil storage tray 12, so that the two oil draining plates 13 are assembled and arranged above the oil-proof cover 20. The two oil draining plates 13 separate the slag and oil dropped by the barbecue, so that the slag remains on the oil draining plates 13 and the oil falls into the oil storage tray 12.

[0032] The mounting frame 14 is fixedly arranged in the housing 11 and is used to carry the motor assembly 15. A first mounting hole 141 through which the barbecue rod assembly 16 is inserted and a second mounting hole 142 through which the following pin 312 of the anti-fooling mechanism 30 is inserted are provided on the mounting frame 14. The first mounting hole 141 and the second mounting hole 142 are installed in cooperation with the anti-fooling mechanism 30, so that only after the oil-proof cover 20 provided with the anti-fooling mechanism 30 is assembled, the barbecue rod assembly 16 can pass through the first mounting hole 141 and be connected to the motor assembly 15.

[0033] The motor assembly 15 includes a motor 151 fixedly arranged on the mounting frame 14 and a cross output head 152 fixedly connected to the barbecue rod assembly 16. The cross output head 152 is inserted and fixed to the barbecue rod assembly 16, so that the motor 151 can drive the barbecue rod assembly 16 to rotate, so that the barbecue on the barbecue rod assembly 16 is evenly heated.

[0034] The roasting rod assembly 16 includes a roasting rod 161 and a connecting member 162 fixedly provided on the roasting rod 161. The connecting member 162 sequentially passes through the second chute 131, the oil-proof cover 20, the chute 121, the anti-fooling mechanism 30, and the first mounting hole 141, and finally is plugged and assembled with the motor assembly 15. The connecting member 162 is used to connect to the cross-shaped output head 152 of the motor assembly 15, so a plug slot is provided on the connecting member 162. It can be imagined that in order to enable the roasting rod assembly 16 to rotate smoothly, a bearing can also be provided between the connecting member 162 and the mounting frame 14 to reduce friction.

[0035] As Figure 8 shown, the oil-proof cover 20 is a trough-shaped structure and is covered outside the chute flange 122 for shielding the chute 121 to prevent oil stains from falling into the chute 121 and contaminating the motor assembly 15. The oil-proof cover 20 is movably sleeved on the chute flange 122. The length of the oil-proof cover 20 can be greater than or equal to twice the length of the chute 121, so that the oil-proof cover 20 still covers the chute 121 when it moves. The height of the oil-proof cover 20 can be less than the height of the chute flange 122, so that the oil-proof cover 20 can avoid generating noise due to friction with the oil storage pan 12 when it moves.

[0036] The anti-fooling mechanism 30 includes a pin assembly 31 fixedly connected to the oil-proof cover 20, an auxiliary mounting plate 32 provided between the oil storage pan 12 and the mounting frame 14, and a torsion spring shielding assembly 33 provided on one side of the mounting frame 14 facing the pin assembly 31.

[0037] The pin assembly 31 includes a mounting plate 311 fixedly connected to the oil-proof cover 20 and a pin 312 fixedly provided on one side of the mounting plate 311 facing the torsion spring shielding assembly 33. The mounting plate 311 is fixedly connected to the pin 312. The mounting plate 311 is used to fixedly mount the pin 312 on one side of the oil-proof cover 20 facing the mounting frame 14. Since the pin assembly 31 is fixedly provided on the oil-proof cover 20, when assembling the roasting rod assembly 16 to the motor assembly 15, only when the oil-proof cover 20 is placed on the chute flange 122 can the pin assembly 31 open the second mounting hole 142, and then the connecting member 162 can be inserted into the first mounting hole 141 to connect with the motor assembly 15, achieving the anti-fooling purpose.

[0038] The bolt 312 passes through the auxiliary mounting plate 32. The bolt 312 includes a guiding surface 3121 provided at the end of the bolt 312, and a clamping groove 3122 provided above the guiding surface 3121. The guiding surface 3121 is inclined from small to large starting from the end of the bolt 312. The bolt 312 corresponds to the second mounting hole 142 and is inserted into the second mounting hole 142 when the oil-proof cover 20 is covered on the chute flange 122. The tip of the bolt 312 is arranged corresponding to the gap between the second mounting hole 142 and the torsion spring shielding assembly 33, so that during the process of inserting the bolt 312 into the second mounting hole 142, it can squeeze into the gap and gradually expand the gap until it is completely inserted into the second mounting hole 142, until the torsion spring shielding assembly 33 completely opens the second mounting hole 142. The clamping groove 3122 is provided on the bolt 312 and is clamped with the torsion spring shielding assembly 33, so that when the clamping groove 3122 moves up and down after clamping, its groove wall will be blocked by the torsion spring shielding assembly 33, and further, the oil-proof cover 20 cannot be pulled out randomly due to the clamping of the bolt 312 and the torsion spring shielding assembly 33, making the installation of the oil-proof cover 20 more stable.

[0039] The auxiliary mounting plate 32 is fixedly arranged on the mounting frame 14, and is provided with a barbecue rod guiding cylinder 321 and a bolt guiding cylinder 322 thereon. The barbecue rod guiding cylinder 321 corresponds to the first mounting hole 141, and the bolt guiding cylinder 322 corresponds to the second mounting hole 142, and both of them play a guiding role. That is, when the first mounting hole 141 is not blocked, after the connecting piece 162 is inserted into the barbecue rod guiding cylinder 321, the connecting piece 162 only needs to continue to move in the same direction to be inserted into the first mounting hole 141. After the bolt is inserted into the bolt guiding cylinder 322, it only needs to continue to move in the same direction to be inserted into the second mounting hole 142.

[0040] As Figure 3 shown, the torsion spring shielding assembly 33 includes a shielding plate 331 rotatably arranged on the mounting frame 14, a torsion spring assembly 332 fixedly arranged on the shielding plate 331 and the mounting frame 14, a semi-shielding hole 333 arranged on the shielding plate 331, and a roller 334 arranged corresponding to the bolt 312.

[0041] The baffle 331 is arranged in cooperation with the plug component 31 and has two states. When the plug 312 of the plug component 31 is not inserted into the second mounting hole 142, the baffle 331 shields the first and second mounting holes 141 and 142, so that the connecting member 162 cannot be inserted and assembled with the cross output rod 152. When the plug 312 is inserted into the second mounting hole 142, the plug 312 pushes the baffle 331 to rotate, so that the baffle 331 does not shield or does not completely shield the first and second mounting holes 141 and 142, that is, the first and second mounting holes 141 and 142 are exposed, and thus the connecting member 162 can pass through the first mounting hole 141 and then be inserted into the cross output rod 152. Therefore, the size of the baffle 331 should be such that it can shield the first and second mounting holes 141 and 142 when the plug 312 is not inserted into the second mounting hole 142, and can open the first and second mounting holes 141 and 142 when the plug 312 is inserted into the second mounting hole 142.

[0042] As Figure 6 shown, the torsion spring assembly 332 includes a torsion spring 3321 arranged on the baffle 331, a connecting rod 3322 arranged at one end of the torsion spring 3321, a fixing rod 3323 arranged at the other end of the torsion spring 3321, a rotating screw 3324 arranged in the middle of the torsion spring 3321, a limiting rod 3325 arranged beside the plug 312, and a sliding groove 3326 arranged on the baffle 331.

[0043] The torsion spring 3321 itself is a prior art and is used to provide a restoring force for the baffle 331.

[0044] The connecting rod 3322 is only fixedly arranged on the shielding plate 331, the fixing rod 3323 is only fixedly arranged on the mounting frame 14, the rotating screw 3324 fixes the torsion spring 3321 on the shielding plate 331 and the mounting frame 14, and the free end of the torsion spring 3321, i.e., the end where the connecting rod 3323 is located, is rotatably arranged on the mounting frame 14. Thus, when the shielding plate 331 is abutted by the bolt 312, the shielding plate 331 can rotate around the rotating screw 3324, and at the same time, the torsion spring 3321 is twisted to store elastic force. When the bolt 312 is pulled out from the second mounting hole 142, the shielding plate 331 returns to its original position under the restoring force of the torsion spring 3321. When the bolt 312 is not inserted into the second mounting hole 142, the shielding plate 331 covers the first mounting hole 141. When the oil shield 20 is mounted on the chute flange 122, the bolt 312 is inserted into the second mounting hole 142, and the shielding plate 331 is pushed by the bolt 312. At this time, the shielding plate 331 covering the first mounting hole 141 moves to expose the first mounting hole 141, so that the connecting member 162 can be inserted into the first mounting hole 141. When the bolt 312 is pulled out from the second mounting hole 142, the shielding plate 331 covers the first and second mounting holes 141 and 142 again.

[0045] The limiting rod 3325 is fixedly arranged on the mounting frame 14 and is located in the sliding groove 3326. When the shielding plate 331 moves, the limiting rod 3325 moves relative to the shielding plate 331.

[0046] The groove length of the sliding groove 3326 is greater than the diameter of the limiting rod 3324. The sliding groove 3326 and the limiting rod 3325 are arranged to limit the moving range of the shielding plate 331 to prevent the shielding plate 331 from having too large a moving range and interfering with other components.

[0047] The semi-blocking hole 333 covers the upper part of the first mounting hole 141 when the bolt 312 is not inserted into the second mounting hole 142, so that the area of the unblocked first mounting hole 141 is smaller than the cross-sectional area of the end of the connecting member 162, thereby preventing the connecting member 162 from being inserted into the first mounting hole 141. When the oil shield 20 is mounted on the chute flange 122, the bolt 312 is inserted into the second mounting hole 142 and pushes the shielding plate 331, and the semi-blocking hole 333 moves with the shielding plate 331 to expose the first mounting hole. When an opening for installing the connecting member 162 is left in the first mounting hole 141, the connecting member 162 can pass through the first mounting hole 141 and be inserted into the cross-shaped output rod 152.

[0048] The roller 334 is arranged at the edge of the shielding plate 331, and the gap between the roller 334 and the second mounting hole 142 corresponds to the end of the plug pin 312. The roller 334 is used to reduce the frictional force between the guiding surface 3121 of the plug pin 312 and the shielding plate 331, so that it is more labor-saving to insert the plug pin 312. During the process of inserting the plug pin 312 into the second mounting hole 142, the guiding surface 3121 of the plug pin 312 is inserted into the gap between the roller 334 and the second mounting hole 142, and under the cooperation of the torsion spring assembly 332, the semi-shielding hole 333 on the shielding plate 331 is pushed to no longer shield the first mounting hole 141, so as to facilitate the connecting member 162 to pass through the first mounting hole 141 and be inserted into the cross output rod 152.

[0049] During installation, first place the oil-proof cover 20 on the oil storage pan 12, place the oil-draining plate 13 on the oil storage pan 12, then sequentially pass the connecting member 162 through the oil-draining plate 13, the oil-proof cover 20, the sliding groove 121, the mounting plate 311, the barbecue rod guiding cylinder 321, and finally insert it into the cross output rod 152. When placing the oil-proof cover 20 on the sliding groove flange 122, the plug pin 312 passes through the auxiliary mounting plate 32 and enters the second mounting hole 142 from the gap between the roller 334 and the second mounting hole 142. The plug pin 312 pushes the shielding plate 331 to completely expose the second mounting hole 142. At this time, the shielding plate 331 covering the first mounting hole 141 rotates around the rotating screw 3324, so that the connecting member 162 can pass through the first mounting hole 141 and finally be inserted and fixed to the cross output rod 152 of the motor assembly 15.

[0050] Compared with the prior art, the oven with an anti-fooling and anti-oil shield structure provided by the present invention sets the anti-fooling mechanism 30 to achieve the anti-fooling function that the barbecue rod assembly 16 cannot be installed without installing the oil shield 20, thereby avoiding the omission of installing the oil shield 20, and further avoiding the oil stain leaking onto the motor assembly 15 and polluting the motor assembly 15. The anti-fooling mechanism 30 sets the baffle 331 and the torsion spring assembly 332, so that when the bolt 312 is not inserted into the second mounting hole 142, the baffle 331 covers the first and second mounting holes 141, 142. When the oil shield 20 is placed on the chute flange 122, the bolt 312 fixedly arranged on the oil shield 20 passes through the chute 121 and the bolt guide cylinder 322 and finally inserts into the second mounting hole 142. At the same time, the bolt 312 pushes the baffle 331, so that the first mounting hole 141 is exposed, and thus the connecting piece 162 can be inserted. Through the anti-fooling mechanism 30, it can be ensured that only after the oil shield 20 is assembled, the barbecue rod assembly 16 can be assembled, thereby achieving the purpose of avoiding the omission of installing the oil shield 20, and further ensuring the normal service life of the oven.

[0051] The above are only the preferred embodiments of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements or improvements within the spirit of the present invention are all covered within the scope of the claims of the present invention.
