[0053] In order to keep the following description of the embodiments of the present application clear and concise, detailed descriptions of known functions and known components are omitted in this application.

[0054] The embodiment of the present application provides an automatic smoke ignition and extinguishing device, which is used in a smoke oven. The smoke oven includes a box body 8, and a box opening 81 is provided on one side of the box body 8. Figures 1 to 9 As shown, the automatic smoke ignition and extinguishing device includes a base 1, a smoke box 2, a waste recovery box 3 and a heating element 4.

[0055] like Figure 11 and Figure 12 As shown, the base 1 is arranged in the box body 8 and close to one side of the box body 8. The base 1 has a chamber 11 (see Figure 2 ), the base 1 is provided with a smoke outlet 13 and a drawer opening communicating with the chamber 11. The box opening 81 on the box body 8 corresponds to the drawer opening, that is, the chamber 11 is communicated with the outside world through the drawer opening and the box opening 81.

[0056] like Figure 1 As shown, the smoking box 2 can be placed in the chamber 11 of the base 1 through the box opening 81 and the drawer opening, and the smoking box 2 can also be taken out from the chamber 11 of the base 1 through the drawer opening. The smoking box 2 is used to contain smoking material 9, and the smoke generated by the smoking material 9 can be discharged into the cooking cavity 84 in the box body 8 through the smoke outlet 13 of the base 1. Figure 11 .

[0057] like Figure 1 As shown, the waste recovery box 3 can be placed in the chamber 11 of the base 1 through the box opening 81 and the drawer opening, and the waste recovery box 3 can also be taken out from the chamber 11 of the base 1 through the drawer opening. When the fumigation box 2 and the waste recovery box 3 are both placed in the chamber 11, the waste recovery box 3 is located below the fumigation box 2. The waste recovery box 3 is used to receive the waste dropped from the fumigation box 2. Figure 12The waste recycling box 3 may contain liquid 10 such as water, which is used to extinguish the waste in time when it is not completely burned, so as to avoid potential safety hazards such as fire.

[0058] Heating element 4 is mounted on base 1 or smoker box 2 and is used to heat smoking material 9 within smoker box 2, causing the smoking material 9 to generate smoke. Heating element 4 is connected to the smoker oven's control system, which activates or deactivates the heating element according to the smoker oven's cooking mode, thereby automatically generating smoke from smoker box 2.

[0059] The fumigation box 2 and the waste recovery box 3 of the automatic smoke ignition and extinguishing device of the embodiment of the present application are both drawer-type and are arranged in a horizontally pull-out manner in the chamber 11 of the base 1, which facilitates the loading and unloading of the fumigation box 2 and the waste recovery box 3 on the fumigation oven. Even during the fumigation process, the user can remove the fumigation box 2 from the housing 8 and add fumigating materials 9 to the fumigation box 2, or discharge the burnt waste into the waste recovery box 3. This facilitates the feeding and discharging operations of the fumigation box 2, avoids the waste of fumigating materials 9, and effectively controls the fumigation time. Moreover, by providing the waste recovery box 3, the burnt and / or unburnt fumigating materials 9 dropped from the fumigation box 2 can be received, preventing the unburnt fumigating materials 9 from falling into the housing 8 and causing safety accidents such as fire. Since the fumigation box 2 can be removed at any time, the fumigation end time can be controlled at any time.

[0060] It is understood that the amount of smoke generated is related to the amount of smoking material 9 added. When there is more smoking material 9, the amount of smoke generated is generally higher, and when there is less smoking material 9, the amount of smoke generated is generally lower. Therefore, by adjusting the amount of smoking material 9 in the smoking box 2, the amount of smoke generated can be adjusted. In this application, since the smoking box 2 can be removed at any time, the user can adjust the amount of smoking material 9 added to the smoking box 2 according to the required amount of smoke, thereby achieving the adjustment of the smoke volume.

[0061] The specific location and structural form of the heating element 4 are not specifically limited in this application. For example, the heating element 4 can be located above the fumigation box 2 to heat the fumigating material 9 in the fumigation box 2 by heat radiation, causing the fumigating material 9 to generate smoke. The heating element 4 can also be located around the outside of the fumigation box 2 to transfer heat to the fumigating material 9 in the fumigation box 2 by heat transfer, causing the fumigating material 9 to generate smoke. The heating element 4 shown in the embodiment of this application is located on the top wall of the chamber 11 of the base 1 and directly faces the fumigating material 9, so that the heat generated by the heating element 4 can be effectively radiated to the fumigating material 9. The heating element 4 can be a heating tube, which has a simple structure, is easy to install, and has a good heating effect.

[0062] In some embodiments, as Figure 3 and Figure 4As shown, the top of the smoking box 2 is open and communicates with the smoke outlet 13 of the chamber 11 (see Figure 11 and Figure 12 ) so that the smoke generated in the smoking box 2 can be discharged into the cooking cavity 84 in the box body 8 through the smoke outlet 13. Figures 3 to 7 As shown, the bottom of the fumigation box 2 is provided with a bottom cover 22, which can be flipped open to discharge the burned waste in the fumigation box 2 into the waste recovery box 3. By providing the bottom cover 22 that can rotate relative to the fumigation box 2, the waste in the fumigation box 2 is easily discharged, and the convenience of operation is improved.

[0063] like Figure 3 As shown, a pivot 222 is provided on one side of the bottom cover 22, and both ends of the pivot 222 are pivotally connected to the opposite sides of the bottom opening of the smoke box 2, so that the bottom cover 22 is rotatably connected to the bottom opening of the smoke box 2 and can be rotated relative to the smoke box 2 to have a first position of closing the bottom opening (see Figure 4 and Figure 5 ) and a second position with the bottom opening (see Figure 6 ).like Figure 3 The bottom cover 22 is provided with a locking hole 221 on its circumference. Figure 7 As shown, a through hole 21 is provided on the smoking box 2 , and when the bottom cover 22 is in the first position of the closed state, the locking hole 221 corresponds to the through hole 21 .

[0064] In some embodiments, the automatic smoke ignition and extinguishing device further includes a lock assembly 5, such as Figures 3 to 7 As shown, the lock assembly 5 includes a lock 51, which is rotatably mounted on the outside of the fumigation box 2 and has a locking portion 511. The lock 51 can rotate under the action of an external force and has a first state and a second state. When the lock 51 is in the first state, the locking portion 511 extends through the through hole 21 into the locking hole 221, locking the bottom cover 22 to the fumigation box 2, maintaining the bottom cover 22 in the first position closing the bottom opening of the fumigation box 2. When the lock 51 is in the second state, the locking portion 511 disengages from the locking hole 221, releasing the lock between the bottom cover 22 and the fumigation box 2, allowing the bottom cover 22 to rotate from the first position to the second position, thereby opening the bottom opening of the fumigation box 2 and allowing waste materials in the fumigation box 2 to be discharged. The provision of the lock 51 facilitates the control of the opening and closing of the bottom cover 22, improving operational convenience.

[0065] In some embodiments, as Figure 3As shown, the lock assembly 5 also includes a lock bracket 52 and a reset component 53. A locking portion 511 is provided on the side of the first end of the lock buckle 51 facing the smoke box 2, and a pressing portion 512 is formed on the side of the second end of the lock buckle 51 away from the smoke box 2. The reset component 53 is provided between the second end of the lock buckle 51 and the smoke box 2, and is used to apply a force to the second end of the lock buckle 51 to rotate it in a direction away from the smoke box 2. The lock bracket 52 is provided on the outside of the smoke box 2 and presses against the middle part of the side of the lock buckle 51 away from the smoke box 2, limiting the lock buckle 51 on the outside of the smoke box 2 and allowing the lock buckle 51 to rotate with its middle part as the rotation axis, so that when the pressing portion 512 of the lock buckle 51 is pressed, the second end of the lock buckle 51 rotates in a direction closer to the smoke box 2 and the first end of the lock buckle 51 rotates in a direction away from the smoke box 2. The lock buckle 51 rotates to the second state, and the locking portion 511 on the first end of the lock buckle 51 is released from the bottom cover. When the pressing portion 512 is released, the second end of the lock catch 51 rotates away from the fumigation box 2 under the action of the reset member 53, driving the first end of the lock catch 51 to rotate toward the fumigation box 2, thereby resetting the lock catch 51 to the first position. The locking portion 511 of the first end of the lock catch 51 extends into the locking hole 221 of the bottom cover 22, locking the bottom cover 22 in the first position closing the bottom opening of the fumigation box 2. The lock catch assembly 5 has a simple and reasonable structure, and the lock catch 51 forms a seesaw-like structure, which is not only easy to operate but also effectively ensures the locking and unlocking of the bottom cover 22.

[0066] like Figure 3 As shown, the central portion of the lock buckle 51 is formed into a shaft-like structure, and the outer side of the fumigation box 2 is formed with an arc-shaped groove 24 that fits within the central portion of the lock buckle 51. The lock buckle bracket 52 is similar to a spring-like structure and is fixed to the fumigation box 2 via fasteners such as screws 54. The lock buckle bracket 52 presses the central portion of the lock buckle 51 into the arc-shaped groove 24 from the outside of the lock buckle 51, thereby facilitating the rotation of the lock buckle 51 about its central axis. To prevent the lock buckle 51 from wobbling during rotation, a retaining chamber 23 is formed on the outer side of the fumigation box 2. This retaining chamber 23 is open on the side facing away from the fumigation box 2, and the lock buckle 51 is positioned within this opening. A through hole 21 in the fumigation box 2 extends through the retaining chamber 23, allowing the locking portion 511 of the lock buckle 51, located within the retaining chamber 23, to pass through the through hole 21 and into the locking hole 221.

[0067] In some embodiments, as Figure 8As shown, the automatic smoke ignition and extinguishing device also includes an electromagnet assembly, which includes an electromagnet and a push rod 62. The electromagnet includes an iron core 61 that moves under electromagnetic action. One end of the iron core 61 is opposite to one end of the push rod 62, and the other end of the push rod 62 is opposite to the pressing portion 512 of the lock buckle 51. When the electromagnet is energized, the iron core 61 moves toward the push rod 62 and pushes the push rod 62 against the pressing portion 512, so that the lock buckle 51 rotates to the second state, and the locking portion 511 of the first end of the lock buckle 51 is locked from the closed state. When the electromagnet is de-energized, the iron core 61 moves away from the push rod 62 and resets, releasing the push against the pressing portion 512. The lock catch 51, under the action of the reset member 53, resets from the second position to the first position. The locking portion 511 of the lock catch 51 extends through the through hole 21 into the locking hole 221, locking the bottom cover 22 in the first position closing the smoker 2. The electromagnet assembly can automatically control the opening of the bottom cover 22, discharge the smoking material 9 in the smoker 2, and stop the smoking operation, thus achieving automatic smoke extinguishing.

[0068] The electromagnet assembly can be connected to the control system of the smoke oven, and the control system sets the on and off time of the electromagnet according to the cooking mode of the smoke oven. When the smoke oven is in the baking mode, the control system controls the electromagnet to be in the power-off state all the time; when the smoke oven is in the smoking mode, the control system will set different smoking times according to different smoked ingredients. When the smoking time reaches the corresponding time, the control system controls the electromagnet to be energized, pushes the lock 51 to unlock, opens the bottom cover 22, and discharges the waste in the smoke box 2, thereby stopping the smoking operation. No more smoke is generated in the smoke box 2. When the waste falls into the waste recovery box 3, it is cooled or extinguished by the aqueous solution pre-placed in the waste recovery box 3, i.e., the smoke generation is stopped, and the smoke generation time and smoke volume are effectively controlled. In this way, the food cooking effect is better and the taste is better. When the cooking is finished, the smoke is basically absorbed by the food, and there will be no problem of smoke choking and environmental pollution when the cooking cavity 84 is opened.

[0069] like Figure 8 As shown, the electromagnet assembly may further include a spring 63, which is mounted on the end of the iron core 61 away from the push rod 62 and is used to apply a force to the iron core 61 to move it away from the push rod 62. In this way, when the electromagnet is de-energized, the iron core 61 can retreat under the action of the spring 63 and release the push against the push rod 62, allowing the lock catch 51 to return to the first state under the action of the reset member 53, locking the bottom cover 22 in the first position that closes the smoker box 2.

[0070] Continue to combine Figure 8The electromagnet assembly may further include an electromagnet seat 64, a support frame 65, and an electromagnet fixing bracket 66. The electromagnet is fixed to the electromagnet seat 64, and the electromagnet seat 64 is fixed to the support frame 65 via the electromagnet fixing bracket 66. The support frame 65 is provided on the box body 8. In this way, the electromagnet assembly is installed on the box body 8.

[0071] like Figure 2 As shown, the base 1 is provided with a first through-hole 18, and the push rod 62 is disposed in the first through-hole 18, with one end extending into the cavity 11 of the base 1 and the other end located outside the base 1 and facing one end of the iron core 61. In this way, the push rod 62 can pass through the base 1 and act on the pressing portion 512 of the lock 51.

[0072] In some embodiments, as Figure 2 As shown, a partition 14 is provided on the drawer opening, which divides the drawer opening into a first drawer opening at the top and a second drawer opening at the bottom. The inner peripheral wall of the chamber 11 of the base 1 is provided with a ridge 12, which can correspond to or be connected to the partition 14, and divide the chamber 11 into a combustion chamber 111 corresponding to the first drawer opening and a waste receiving chamber 112 corresponding to the second drawer opening. The fumigation box 2 can be placed in the combustion chamber 111 from the first drawer opening and supported on the ridge 12, and the waste recovery box 3 can be placed in the waste receiving chamber 112 from the second drawer opening. In this way, the fumigation box 2 and the waste recovery box 3 can be smoothly loaded and unloaded in the base 1.

[0073] Further, continue to combine Figure 2 First guide rails 15 are provided on the opposite inner walls of the combustion chamber 111, and first guide slots corresponding to the first guide rails 15 are provided on the opposite outer walls of the fumigation box 2. When the fumigation box 2 is placed in the combustion chamber 111, the first guide slots can slide along the first guide rails 15. This facilitates the installation and movement of the fumigation box 2 in the combustion chamber 111.

[0074] The waste receiving chamber 112 has opposite inner walls provided with second guide rails 16, and the waste recovery box 3 has opposite outer walls provided with second guide slots corresponding to the second guide rails 16. When the waste recovery box 3 is placed in the waste receiving chamber 112, the second guide slots can slide along the second guide rails 16. This facilitates the installation and movement of the waste recovery box 3 in the waste receiving chamber 112.

[0075] In order to facilitate the removal of the fumigation box 2 and the waste recycling box 3, a handle 25 is provided on each of the fumigation box 2 and the waste recycling box 3. Figure 1 and Figure 2 .

[0076] In some embodiments, as Figure 2As shown, retractable positioning pins 17 are connected via elastic components 72 to the opposing inner walls of the combustion chamber 111 and the opposing inner walls of the waste receiving chamber 112. Grooves 24 are also provided on the opposing outer walls of the fumigation box 2 and the outer wall of the waste recovery box 3. When the fumigation box 2 and the waste recovery box 3 are installed in the combustion chamber 111 and the waste receiving chamber 112, respectively, the positioning pins 17 extend into the corresponding grooves 24 to position the fumigation box 2 and the waste recovery box 3, respectively. The positioning pins 17 ensure stability of the fumigation box 2 and the waste recovery box 3 after installation.

[0077] In some embodiments, as Figure 9 As shown, the automatic smoke ignition and extinguishing device further includes a signal switch assembly 7 provided on the base 1. The signal switch assembly 7 includes a push rod 71, an elastic component 72, a switch 73, and an alarm component. The push rod 71 is capable of moving and triggering the switch 73 or releasing the trigger of the switch 73. The elastic component 72 acts on the push rod 71 to exert a force on the push rod 71 to disengage the push rod 71 from the switch 73 and release the trigger of the switch 73. When the waste recycling box 3 is placed in the chamber 11 of the base 1, the waste recycling box 3 presses against the push rod 71, causing the push rod 71 to move toward the switch 73 and trigger the switch 73. The switch 73 sends a first signal to the alarm component, and the alarm component is deactivated. When the waste recycling box 3 is removed from the chamber 11 of the base 1, the push rod 71 moves away from the switch 73 under the action of the elastic component 72 and releases the trigger of the switch 73. The switch 73 sends a second signal to the alarm component, and the alarm component is activated. By setting up the signal switch assembly 7, it is possible to monitor whether the waste recovery box 3 is installed in place, thereby avoiding safety problems such as fire caused by the waste recovery box 3 not being installed due to misoperation during the fumigation process, causing the waste in the fumigation box 2 to be discharged into the oven.

[0078] Further, such as Figure 2 As shown, the bottom of the base 1 is provided with a second through-hole 19, the top of the top rod 71 passes through the second through-hole 19 on the base 1 and extends into the chamber 11, the switch 73 is located below the top rod 71 and opposite to the bottom of the top rod 71, and the switch 73 is fixed to the box 8 of the smoke oven through a switch fixing bracket 74, see Figure 9 . The elastic component 72 can be a spring, which is sleeved on the push rod 71. When the waste recovery box 3 is loaded into the chamber 11, the bottom of the waste recovery box 3 presses downward against the top of the push rod 71, causing the push rod 71 to move downward and trigger the switch 73. The switch 73 sends a first signal to the warning component, and the warning component is not activated and does not issue an alarm reminder. When the waste recovery box 3 is not loaded into the chamber 11, the push rod 71 moves upward under the action of the elastic component 72, releasing the trigger on the switch 73. The switch 73 sends a second signal to the warning component, and the warning component alarms the user, reminding the user to load the waste recovery box 3.

[0079] The specific form of the warning component is not limited, and can be an audio or visual alarm, which reminds the user that he has forgotten to install the waste recycling box 3 by flashing lights or emitting warning sounds. In this embodiment, the warning component can be a buzzer, for example.

[0080] It can be understood that the signal switch component 7 can be selectively enabled or disabled according to different cooking states of the smoke oven. For example, the control system of the smoke oven can control the signal switch component 7 to be disabled in the baking mode and enabled in the smoking mode. In this way, in the baking mode, the warning component will not issue a warning reminder regardless of whether the waste recycling box 3 is loaded.

[0081] The present application also provides a smoking oven, such as Figures 10 to 12 As shown, the smoke oven includes a housing 8 and the automatic smoke generating and extinguishing device of any of the above-mentioned embodiments. The automatic smoke generating and extinguishing device is arranged in the housing 8, and the smoke box 2 and the waste recovery box 3 of the automatic smoke generating and extinguishing device can be taken out or put in through the box opening 81 on the housing 8. Since the smoke box 2 and the waste recovery box 3 of the smoke oven of the embodiment of the present application can be taken out and put in at any time, waste can be automatically discharged at any time and sawdust can be added at any time, thereby effectively controlling the smoke generation time, smoke volume, and smoke generation duration to meet the different smoking effects that users want to achieve for different food ingredients.

[0082] In some embodiments, as Figure 11 and Figure 12 As shown, the housing 8 includes an inner shell 82 and an outer shell 83. The inner shell 82 encloses a cooking cavity 84, and a space 85 for accommodating the base 1 of the automatic smoke ignition and extinguishing device is formed between the inner shell 82 and the outer shell 83. The inner shell 82 is provided with a smoke inlet 86 that is sealed with the smoke outlet 13 of the base 1, so that the smoke generated in the fumigation box 2 enters the cooking cavity 84 through the smoke outlet 13 and the smoke inlet 86, and smokes the food in the cooking cavity 84. The outer shell 83 is provided with a box opening 81, so that the fumigation box 2 and the waste recovery box 3 of the automatic smoke ignition and extinguishing device can enter and exit the cavity 11 of the base 1 through the box opening 81. The housing 8 has a compact structure and a reasonable layout, which is conducive to the installation of the automatic smoke ignition and extinguishing device in the housing 8.

[0083] In order to protect the automatic smoke ignition and extinguishing device and to make the appearance of the whole machine neat, a cover plate 88 can be provided at the box opening 81. Figure 10 , the automatic smoke ignition and extinguishing device is sealed inside the box 8 to prevent it from being exposed.

[0084] It is understood that the automatic smoke ignition and extinguishing device can be provided on any side of the cooking cavity 84 except the front side. For example, the automatic smoke ignition and extinguishing device can be provided on the back side, left side or right side of the cooking cavity 84. Figure 10As shown, in this embodiment, a box opening 81 is provided on the right side of the box body 8, and an automatic smoke generating and extinguishing device is provided on the right side of the cooking cavity 84. Such a layout makes it easy to take the fumigation box 2 and the waste recovery box 3 from the side of the box body 8, making the operation more convenient.

[0085] The housing 8 also includes a door 87 hinged to the front of the housing 8 for pivoting to close and open the cooking chamber 84. A control panel may also be provided on the front of the housing 8. The control panel includes a menu for a baking function and multiple menus for a smoking function corresponding to different smoking ingredients. The user can adjust the cooking mode and cooking time according to the ingredients being smoked. When the smoking function is activated, the control system activates the heating element 4 and heats a smoking material 9, such as wood chips, causing the carbonized wood chips to form smoke (fume). This smoke enters the cooking chamber 84 through the smoke inlet 86 and permeates the food. If wood chips are forgotten or too little wood chips are added before cooking, the smoker box 2 can be removed and added at any time. When cooking is almost complete, the control system deactivates the heating element 4 and automatically activates the electromagnet assembly, opening the bottom cover 22 and discharging the wood chips from the smoker box 2 into the waste recovery box 3. The wood chips are immediately extinguished upon encountering the aqueous solution in the waste recovery box 3. That is, the generation of smoke is stopped, and the generation time and amount of smoke are effectively controlled. In this way, the food cooking effect is better and the taste is better. When the cooking is finished, the smoke is absorbed by the food and disappears.

[0086] The above description is intended to be illustrative rather than restrictive, and those skilled in the art may make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present disclosure. Furthermore, the above examples (or one or more of them) may be used in combination with each other, and it is contemplated that these embodiments may be combined with each other in various combinations or permutations.
