Description

Technical Field

[0001] This invention relates to the field of smokehouse technology, specifically to a smokehouse with a material box anti-ballistic structure. Background Technology

[0002] A smokehouse is used to infuse flavor into food. Different flavorings are produced by the incomplete combustion of ingredients, which generates smoke to provide the desired flavor to the food. These ingredients are generally placed in an ingredient box, which is partially or entirely located inside the smokehouse. A heating element is located below or near the ingredient box, which heats the ingredient box and ignites the ingredients inside, causing them to burn incompletely and produce smoke, thus forming the ingredient box.

[0003] However, in existing technologies, imprecise heat and oxygen control of the material box can lead to overheating. This causes the material inside to burn completely, and the flames ignite the entire smokehouse. The sudden pressure increase within the material box can easily cause it to be ejected from its mounting position within the oven. This ejection is extremely dangerous. First, the high-temperature burning material box being ejected from the oven poses a serious safety threat to operators, potentially causing burns or even fires. Second, the sudden displacement or detachment of the material box disrupts the normal airflow and heat distribution within the oven, abruptly interrupting the smoke generation process and directly affecting the smoking effect and flavor consistency of the food. Third, the ejected material box may collide with the oven's inner wall or other components, causing equipment damage. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a safe fixing structure for smokehouses that can reliably prevent the material box from being ejected due to uncontrolled internal combustion, thereby fundamentally improving the safety and operational stability of the equipment and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a smokehouse with a material box anti-flying structure, comprising a main body, a material box, and a heating tube. The main body has a cavity, and the material box is partially or entirely located within the cavity. The heating tube is used to heat the material box. The material box includes a loading section, and the loading section is provided with a buffer structure for extending the smoke path to suppress the flame. The smokehouse further includes a locking mechanism disposed between the material box and the main body to prevent the material box from being ejected from the main body.

[0006] This invention provides a smokehouse with a material box bulletproof structure. It has the following beneficial effects: 1. The present invention provides a buffer structure in the loading section of the material box. This structure can buffer the gas-solid mixture that is ejected instantaneously when high pressure is generated inside the material box due to abnormal combustion by extending the escape path of the smoke and changing its escape direction. It can also effectively block the direct outward spread of the flame and reduce the risk of the flame spreading to the furnace cavity or outside the equipment.

[0007] 2. The present invention is equipped with a mechanical locking mechanism, which can automatically or manually lock the material box to the furnace wall after it is installed in place. Even if the material box generates high pressure due to abnormal combustion, the locking mechanism can provide a firm mechanical constraint, directly preventing the material box from being ejected from the installation position, and completely eliminating the safety hazards to personnel and equipment caused by ejection.

[0008] 3. The material box seat of this invention wraps around the heating tube and supports the material box, making the heat transfer more uniform and gentle, avoiding local overheating of the material box and direct ignition of the internal material, thus reducing the possibility of complete combustion from the heat source. At the same time, the through holes on the wall of the material box seat promote the flow of hot air, making the heating process more stable and further ensuring that the material is in an ideal state of incomplete combustion.

[0009] 4. The buffer structure of the present invention extends the path and also forms a small expansion cavity, which can initially buffer and release the sudden increase in pressure inside the material box, reducing the instantaneous impact on the material box itself and its connecting structure.

[0010] 5. The locking mechanism of the present invention ensures that the material box is tightly bound to the furnace body in the working state, reducing loosening, abnormal noise and wear caused by vibration or pressure fluctuations, and improving the stability and durability of the overall structure.

Detailed Implementation

[0013] This invention provides a smokehouse with a material box bulletproof structure, such as... Figure 1-9 As shown, this is the first embodiment of the present invention, which includes a main body 1, a material box 3, and a heating tube 2. The main body 1 includes a front door 12 with an open state and a closed state, and five walls surrounding the smokehouse, including a right wall 13, a rear wall 14, a left wall 15, a top wall 16, and a bottom wall 17.

[0014] The main body 1 has a cavity 11, surrounded by a front door 12, a right wall 13, a rear wall 14, a left wall 15, a top wall 16, and a bottom wall 17. The front door 12 is located at the front of the cavity 11, the right wall 13 is located on the right side of the cavity 11, the rear wall 14 is located at the rear of the cavity 11, the left wall 15 is located on the left side of the cavity 11, the top wall 16 is located on the upper side of the cavity 11, and the bottom wall 17 is located on the lower side of the cavity 11. The material box 3 is partially or entirely located inside the cavity 11. When the front door 12 is closed, the front door 12, right wall 13, rear wall 14, left wall 15, top wall 16, and bottom wall 17 together seal the cavity 11. When the front door 12 is open, the user can place food or other items into the cavity 11. Specifically, the front door 12 is rotatably connected to the left wall 15, and the front door 12 and the left wall 15 are rotatably connected by a hinge or a pivot structure; a lock structure 131 is provided on either the right wall 13 or the front door 12. When the front door 12 is in the closed state, the lock structure 131 locks the front door 12 and the right wall 13 to seal the cavity 11 and keep the front door 12 in the closed state; when the lock structure 131 is released, the front door 12 can switch between the closed state and the open state.

[0015] Ventilation holes are provided on the left wall 15, and there are baffles near the ventilation holes to change the size of the ventilation holes. The smokehouse can use the baffles to fully open or completely close the ventilation holes, or the baffles can be used to partially open the ventilation holes as needed to control the airflow into and out of the cavity 11.

[0016] The material box 3 includes a loading section 31, a connecting section 32, and a handle section 33. The connecting section 32 connects the loading section 31 and the handle section 33 and is located between the loading section 31 and the handle section 33. The right wall 13 has a material box hole 132. The material box 3 is installed in the material box hole 132. After the material box 3 is installed, the loading section 31 is located inside the cavity 11, the connecting section 32 is located inside the material box hole 132, and the handle section 33 is located outside the right wall 13. That is, the loading section 31 enters and exits the cavity 11 through the material box hole 132.

[0017] The smokehouse includes a support plate 23 located within the cavity 11. Both ends of the support plate 23 are fixed to the left wall 15 and the right wall 13, respectively, using screws or welding. The support plate 23 supports the heating element 2, a portion of which is fixed to the rear wall 14, with the remaining portion resting on the support plate 23, thus improving the stability of the heating element 2. It is understood that the portion of the heating element 2 fixed to the rear wall 14 does not have heating capability; the portion of the heating element 2 with heating capability is entirely located within the cavity 11. Alternatively, in this embodiment, the portion of the heating element 2 fixed to the rear wall 14 is ignored, and all of the heating element 2 in this embodiment is located within the cavity 11.

[0018] A material box seat 34 is provided on the support plate 23. The material box seat 34 is located above the support plate 23 and fixes the support plate 23 by means of screws, riveting, or welding. The material box seat 34 covers the heating tube 2 and can protect the heating tube 2. Each side of the wall of the material box seat 34 has through holes to facilitate the transfer of heat from the material box seat 34 to the cavity 11, thereby improving the heat convection efficiency.

[0019] The material box base 34 supports the loading part 31. The heating tube 2 is located below the material box 3. The material box base 34 is located below the material box 3. The through hole at the top of the material box 3 facilitates the transfer of heat to the material box 3 for heating the material box 3 so that the material inside the material box 3 produces smoke.

[0020] The filling section 31 includes a front side wall 311, a rear side wall 312, a left side wall 313, and a lid 314, which together form the state space of the filling section 31. The front side wall 311 faces the front door 12 and is closer to the front door 12 than the rear side wall 312; the rear side wall 312 faces the rear wall 14 and is closer to the rear wall 14 than the front side wall 311; the left side wall 313 faces the left wall 15 and is closer to the left wall 15 than the connecting portion 32; the lid 314 faces the top wall 16 and is located above the front side wall 311, rear side wall 312, and left side wall 313. The lid 314 is detachably connected to the filling section 31 to facilitate the user filling the filling section 31 with flavoring materials.

[0021] The lid 314 includes an upper wall 315 and a lower wall 316, which are fixedly connected. The lid 314 has a buffer cavity 317 located between the upper wall 315 and the lower wall 316. The lower wall 316 is used to seal the opening of the filling section 31, and the lower wall 316 is provided with a smoke inlet 318, through which smoke from the filling section 31 enters the buffer cavity 317; the upper wall 315 is provided with a smoke outlet 319, through which smoke from the buffer cavity 317 enters the cavity 11. In the vertical direction, the smoke outlet 319 and the smoke inlet 318 are offset. Specifically, the smoke outlet 319 is located at the right end of the cover 314, and the smoke inlet 318 is located at the left end of the cover 314. Smoke enters the buffer chamber 317 from the loading section 31 through the smoke inlet 318. The smoke moves from the left end to the right end of the buffer chamber 317 and enters the cavity 11 through the smoke outlet 319 of the buffer chamber 317. That is, when the lower wall 316 and the upper wall 315 are projected onto the same horizontal plane, or when the lower wall 316 and the upper wall 315 are projected onto the plane where the lower wall 316 is located, the projection of the smoke outlet 319 and the projection of the smoke inlet 318 do not contact or overlap. Compared to the prior art, where the smoke path goes directly from the loading section 31 to the cavity 11, the smoke path in this embodiment is longer, as it travels from the loading section 31 through the buffer cavity 317 before reaching the cavity 11. In the event of an accidental flame, the longer flame path results in a lower flame height outside the material box 3 or no flame outside the material box 3, thus improving the safety of the smokehouse.

[0022] The connection between the upper wall 315 and the lower wall 316 is sealed, reducing the possibility of smoke escaping at this connection. Multiple smoke inlets 318 and smoke outlets 319 improve smoke extraction efficiency. The diameters of the smoke outlets 319 and smoke inlets 318 are between 3 mm and 6 mm, reducing the possibility of larger particles escaping from either the smoke outlet or smoke inlet.

[0023] The lid 314 is provided with a buckle, and the filling part 31 is provided with a slot, so that the lid 314 and the filling part 31 are connected by the buckle and the slot.

[0024] In other embodiments, the smoke outlet 319 and the smoke inlet 318 are staggered in the height direction. In the left-right direction or the direction in which the loading section 31 enters and exits the cavity 11, the smoke outlet 319 and the smoke inlet 318 are arranged alternately, that is, the smoke outlet 319 is diagonally above two adjacent sets of smoke inlet holes 318, and the smoke inlet 318 is diagonally below adjacent smoke outlet holes 319. When the lower wall 316 and the upper wall 315 are projected onto the same horizontal plane, or when the lower wall 316 and the upper wall 315 are projected onto the plane where the lower wall 316 is located, the projection of the smoke outlet 319 is located between the projections of adjacent smoke inlet holes 318.

[0025] In another embodiment, the loading section 31 includes a front side wall 311, a rear side wall 312, a left side wall 313, and a material box cover 35. The material box cover 35 includes a top wall 351, a left wall 352, a front wall 353, and a rear wall 354. The top wall 351 is located above the loading section 31 and is opposite to the top wall 16; the left wall 352 is opposite to the left side wall 313 and is located between the left side wall 313 and the left wall 15; the front wall 353 is opposite to the front side wall 311 and is located between the front side wall 311 and the front door 12; the rear wall 354 is opposite to the rear side wall 312 and is located between the rear side wall 312 and the rear wall 14.

[0026] The left wall 352 and the left side wall 313 do not contact each other, thus forming a smoke channel between them; a smoke channel is provided between the front wall 353 and the front side wall 311; and a smoke channel is provided between the rear wall 354 and the rear side wall 312. The distance between the front wall 353 and the front side wall 311 is between 1 mm and 3 mm, the distance between the rear wall 354 and the rear side wall 312 is between 1 mm and 3 mm, and the distance between the left wall 352 and the left side wall 313 is between 1 mm and 3 mm. Therefore, the width of the smoke channel is between 1 mm and 3 mm. In this embodiment, the width of the smoke channel is 2 mm. It is understood that those skilled in the art can select the width and number of smoke channels according to actual needs. For example, a smoke channel can be provided between the front wall 353 and the front side wall 311, and between the rear wall 354 and the rear side wall 312. There is no smoke channel between the left wall 352 and the left side wall 313. That is, the front wall 353 and the front side wall 311 do not contact each other, the rear wall 354 and the rear side wall 312 do not contact each other, and the front wall 353 and the front side wall 311 are closely attached to each other. The width of the smoke channel can be between 3 mm and 10 mm, and the specific value can be selected as needed. In this embodiment, the smoke channel is the buffer cavity 317 in the first embodiment described above. The smoke channel has a width, and the smoke channel has an outlet at the lower part in the vertical direction. Smoke enters the cavity 11 from the outlet of the smoke channel.

[0027] At least one of the three side walls 311, 312, and 313 has a smoke inlet 318. The smoke inlets 318 are all located at the upper part of the front side wall 311, rear side wall 312, and / or left side wall 313, facilitating the entry of the rising hot smoke from the loading section 31 into the buffer chamber 317, while simultaneously reducing the possibility of material clogging the smoke outlet. The left wall 352 completely covers the smoke inlet 318 located on the left side wall 313; the front wall 353 completely covers the smoke inlet 318 located on the front side wall 311; and the rear wall 354 completely covers the smoke inlet 318 located on the rear side wall 312. In the vertical height direction, the height of the front wall 353 is less than or equal to the height of the front side wall 311, but the height of the front wall 353 is greater than or equal to half the height of the front side wall 311; the height of the left wall 352 is less than or equal to the height of the left side wall 313, but the height of the left wall 352 is greater than or equal to half the height of the left side wall 313; the height of the rear wall 354 is less than or equal to the height of the rear side wall 312, but the height of the rear wall 354 is greater than or equal to half the height of the rear side wall 312; therefore, the height of the buffer cavity 317 is greater than or equal to half the height of the front side wall 311, and the height of the buffer cavity 317 is less than or equal to the height of the front side wall 311.

[0028] The material box cover 35 is equipped with a buckle, and the loading part 31 is equipped with a slot that matches the buckle. The material box cover 35 and the loading part 31 are connected and fixed by the buckle and the slot. When the heating tube 2 heats the loading part 31, the top wall 351 of the material box cover 35 closes the opening of the loading part 31. The smoke generated inside the loading part 31 enters the buffer chamber 317 through the smoke inlet 318. The smoke accumulates in the buffer chamber 317. As the pressure inside the buffer chamber 317 gradually increases, the smoke moves downward and enters the cavity 11 from the lower outlet of the buffer chamber 317. This extends the path of the smoke from the loading part 31 to the cavity 11. The extended length is the length from the smoke inlet 318 to the outlet of the buffer chamber 317. In the event of an accidental flame, the longer flame path results in a lower flame height outside the material box 3 or no flame outside the material box 3, improving the safety of the smokehouse.

[0029] like Figures 10-12As shown, this is the second embodiment of the present invention. This embodiment is the same as the device in the first embodiment, except that the bottom of the handle 33 of the material box 3 is provided with a grip 331 for easy hand holding by the user. The handle 33 is provided with an installation chamber 337, and a guide seat 336 is fixedly provided in the installation chamber 337. The guide seat 336 is provided with a slot. A lifting frame 334 that can be raised and lowered is provided above the guide seat 336. The top of the lifting frame 334 is U-shaped. One end of the lifting frame 334 passes through one side of the top of the handle 33 and is fixedly provided with a locking tongue 333. The other side of the lifting frame 334 passes through the other side of the top of the handle 33 and is connected to a push button 332. The bottom of the lifting frame 334 is provided with a plug rod that is inserted into the slot in the guide seat 336 to achieve the effect of raising and lowering and guiding movement. A return spring 335 is installed between the bottom of the lifting frame 334 and the top of the guide seat 336.

[0030] Specifically, the user holds the grip 331 and pushes the material box 3 into the material box hole 132, so that the loading part 31 is completely placed in the cavity 11 and supported by the material box seat 34, while the connecting part 32 is in contact with the inner wall of the material box hole 132. During this process, the pressing button 332 and the locking tongue 333 are kept in the initial raised position due to the elastic force of the return spring 335.

[0031] When the material box 3 is pushed into place, the user presses down the button 332, which drives the lifting frame 334 to overcome the elastic force of the return spring 335 and move downward along the slot of the guide seat 336. The downward movement of the lifting frame 334 drives the locking tongue 333 connected to it to move downward in sync, so that the lower end of the locking tongue 333 drops down and cooperates with the material box 3 to be fully inserted into the material box hole 132. When the user releases the button 332, the locking tongue 333 is reset under the elastic force of the return spring 335 and fits against the right wall 13 to form a lock, thereby achieving the anti-rebound effect of the material box 3.

[0032] When it is necessary to remove the material box 3, the user presses the button 332 down again. At this time, the locking tongue 333 is driven down, the locking of the material box 3 is released, and it can be pulled out smoothly.

[0033] like Figures 13-15As shown, this is the third embodiment of the present invention. This embodiment is the same as the device in the first embodiment, except that the handle part 33 of the material box 3 has a handle protrusion 330 on the right side, the handle protrusion 330 has a handle cavity 365 inside, the connecting part 32 has a transmission cavity 363 inside, and a crossbar support shaft 364 is rotatably provided between the front and rear walls inside the transmission cavity 363. A Z-shaped connecting rod 367 is installed on the outer end face of the support shaft 364. A rotating handle 366 is provided at the right end of the Z-shaped connecting rod 367. One end of the Z-shaped connecting rod 366 extends outward into the handle cavity 365. The lower end of the rotating handle 366 is U-shaped for easy hand handling and rotation. A vertical plate is provided at the bottom right end of the Z-shaped connecting rod 367. A connecting rod return spring 368 is installed between the vertical plate and the left wall of the transmission cavity 363.

[0034] Furthermore, a lifting and moving pin 361 is provided on the left side of the transmission cavity 363, and an opening is provided on the left side of the connecting part 32. The top of the pin 361 passes through the opening on the left side of the connecting part 32 and maintains the lifting and guiding movement effect therewith. A reset spring 369 is fixedly connected between the bottom of the pin 361 and the lower wall of the transmission cavity 363. A connecting groove 362 is provided on the right side of the pin 361, and the left end of the Z-shaped connecting rod 367 is inserted into the connecting groove 362.

[0035] Specifically, the user holds the lower U-shaped end of the rotating handle 366 inside the handle protrusion 330 and pushes the material box 3 into the material box hole 132, so that the loading part 31 is completely placed in the cavity 11 and supported by the material box seat 34. At this time, under the lifting force of the user's hand, the rotating handle 366 moves upward, which drives the right side of the Z-shaped connecting rod 367 to move upward. Through the support of the supporting shaft 364, the left side of the Z-shaped connecting rod 367 is driven to descend, thereby connecting the left side of the Z-shaped connecting rod 367 with the connecting groove 362 in the pin 361, driving the pin 361. Overcoming the elastic force of the reset spring 369, it moves downward and retracts into the transmission cavity 363, making room for the smooth insertion of the material box 3. When the loading part 31 is fully supported by the material box seat 34 and the connecting part 32 is in place with the inner wall of the material box hole 132, the user releases the lower U-shaped end of the hand-held rotating handle 366. At this time, the pin 361 is reset under the elastic force of the reset spring 369 and is in place with the right wall 13, forming a lock, thereby achieving the anti-rebound effect of the material box 3. At the same time, the Z-shaped connecting rod 367 is reset under the elastic force of the connecting rod reset spring 368.

[0036] When unlocking, the user holds the lower U-shaped end of the rotating handle 366 inside the handle protrusion 330 and lifts it upwards. Under the lifting force of the user's hand, the rotating handle 366 moves upwards, which drives the right side of the Z-shaped link 367 to move upwards. Through the support of the support shaft 364, the left side of the Z-shaped link 367 moves downwards. Thus, the left side of the Z-shaped link 367 connects with the connecting groove 362 in the pin 361, driving the pin 361 to overcome the elastic force of the reset spring 369, move downwards and retract into the transmission cavity 363. At this time, the locking of the material box 3 is released, and it can be easily pulled out.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
