[0036] 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.

[0037] like Figures 1 to 3As shown, an embodiment of the present application provides a smoke oven, comprising a housing 1, a smoking assembly 2, a circulating air assembly, and an exhaust vent opening and closing control system 3. The housing 1 includes a cooking chamber 111, a hot air generating chamber 121 disposed outside the cooking chamber 111, ventilation holes 112 disposed on the walls of the cooking chamber 111, and exhaust vents 123 disposed on the housing 1, communicating with the hot air generating chamber 121. The smoking assembly 2 is disposed within the housing 1, outside the cooking chamber 111, and is configured to generate smoke, which is then introduced into the cooking chamber 111 to smoke the food within the cooking chamber 111. The circulating air assembly is disposed within the housing 1, outside the cooking chamber 111, and is configured to generate hot air within the hot air generating chamber 121. The circulating air assembly is further configured to circulate hot air or smoke within the hot air generating chamber 121 and the cooking chamber 111. The exhaust vent opening and closing control system 3 is arranged at the exhaust vent 123 and is used to selectively open or close the exhaust vent when the smoke oven is in different cooking modes. In addition to the baking function of a conventional oven, the smoke oven also has a smoking function.

[0038] The smoke oven of the embodiment of the present application increases the smoking function by providing a smoking component 2 to meet the user's demand for smoked taste. Moreover, by providing an exhaust vent opening and closing control system 3, the exhaust vent 123 can be opened in the baking mode to discharge the steam generated during the baking process out of the cooking cavity 111, and the exhaust vent 123 can be closed in the smoking mode to prevent the smoke in the cooking cavity 111 from leaking out through the exhaust vent 123, causing environmental pollution and waste of smoke, and also to prevent the smoke from choking the user, thereby improving the user experience.

[0039] In some embodiments, as Figure 1 and Figure 2 As shown, the smoking assembly 2 includes a smoking box 21, a waste collection box 22, and a heating element 23 for heating the smoking material 25 in the smoking box 21. A smoke outlet 213 is provided at the top of the smoking box 21. The waste collection box 22 is open at the top and located below the smoking box 21, catching the burned waste that falls from the bottom of the smoking box 21. A smoke inlet 113 is provided on the wall of the cooking chamber 111, communicating with the smoke outlet 213. The smoking assembly 2 has a simple and rational structure, allowing generated smoke to enter the cooking chamber 111 smoothly, and the burned waste (ash) is collected by the waste collection box 22 to avoid contamination of the smoking oven.

[0040] Continue to combine Figure 2The fumigation box 21 can be open at the top, forming a smoke outlet 213. A heating element 23 can be positioned above the fumigation box 21 to heat the smoking material 25 within the fumigation box 21 by heat radiation, causing the smoking material 25 to generate smoke. The heating element 23 can also be positioned around the outside of the fumigation box 21, transferring heat to the smoking material 25 within the fumigation box 21 through heat conduction, causing the smoking material 25 to generate smoke. The heating element 23 can be a heating tube, which has a simple structure, is easy to install, and provides excellent heating performance.

[0041] In some embodiments, as Figure 2 As shown, the bottom of the fumigation box 21 is provided with a bottom cover 211, which is provided with an ash hole (not shown in the figure). The bottom cover 211 can be flipped open to allow the burned waste in the fumigation box 21 to be discharged into the waste recovery box 22. The ash hole in the bottom cover 211 not only allows ashes to fall through the ash hole into the waste recovery box 22, preventing excessive ashes from affecting the production of smoke from the fumigation material 25, but also allows air to enter the fumigation box 21 through the ash hole, facilitating the production of smoke from the fumigation material 25.

[0042] In some embodiments, as Figure 1 As shown, a mounting bracket 24 is provided on the outer wall of the cooking cavity 111. A mounting cavity is formed within the mounting bracket 24. A smoke passage 241 is provided at the top of the mounting bracket 24, communicating with the mounting cavity. A first end of the smoke passage 241 is sealedly connected to the smoke inlet 113. The smoke box 21 and the waste recovery box 22 are both drawer-type and are laterally retractable within the mounting cavity of the mounting bracket 24. The smoke outlet 213 of the smoke box 21 is sealedly connected to the other end of the smoke passage 241. The mounting bracket 24 facilitates the installation and removal of the smoke box 21 and the waste recovery box 22 from the housing 1. Even during the smoking process, the user can remove the smoke box 21 from the housing 1, discharge the burnt waste into the waste recovery box 22, and add smoking material 25 to the smoke box 21. This facilitates the loading and unloading of the smoke box 21, improving ease of use.

[0043] like Figure 3 As shown, the box body 1 is provided with a through opening 122 corresponding to the mounting cavity of the mounting frame 24, and the fumigation box 21 and the waste recovery box 22 can be installed on the mounting frame 24 through the through opening 122. The state after the fumigation box 21 and the waste recovery box 22 are installed on the mounting frame 24 is as shown. Figure 1 In order to facilitate the removal of the fumigation box 21 and the waste recycling box 22, a handle 212 is provided on each of the fumigation box 21 and the waste recycling box 22. Figure 1 and Figure 2 .

[0044] It is understood that the smoke assembly 2 and the circulating air assembly can be separately or simultaneously arranged on any side of the cooking cavity 111 except the front side. For example, the smoke assembly 2 and the circulating air assembly are both arranged on the rear side, left side or right side of the cooking cavity 111, and the smoke assembly 2 and the circulating air assembly are respectively arranged on the rear side and left side of the cooking cavity 111. Figure 3 As shown, in this embodiment, the fumigation assembly 2 is arranged on the right side of the cooking cavity 111, and the circulating air assembly is arranged on the rear side of the cooking cavity 111. Such a reasonable layout structure facilitates the fumigation box 21 and the waste recovery box 22 to be taken from the side of the box body 1, making the operation more convenient.

[0045] In some embodiments, as Figure 2 and Figure 3 As shown, the box body 1 includes an inner cavity 11 and an outer shell 12 provided on the outer periphery of the inner cavity 11. The inner cavity 11 is a hollow cubic structure with an open front side. A cooking cavity 111 is formed in the inner cavity 11. The right side plate of the inner cavity 11 is provided with a smoke inlet 113 (see Figure 5 ), the rear side plate of the inner cavity 11 is provided with a ventilation hole 112 (see Figure 3 The circulating air assembly is located between the rear panel of the inner cavity 11 and the outer cavity 12; the smoking assembly 2 is located between the right side panel of the inner cavity 11 and the outer cavity 12. The front side of the outer cavity 12 is open and has a door 13. The door 13 is hinged to the outer cavity 12 and can rotate relative to the outer cavity 12 to close or open the cooking cavity 111.

[0046] In some embodiments, as Figures 6 to 8 As shown, the exhaust vent opening and closing control system 3 includes a power component, a gear 32, a rack drive rod 33, and a baffle 34. The power component is connected to the gear 32 to drive the gear 32 to rotate. The rack drive rod 33 meshes with the gear 32 so that it moves linearly under the drive of the gear 32 when the gear 32 rotates. The baffle 34 is connected to one end of the rack drive rod 33 and moves with the rack drive rod 33 when the rack drive rod 33 moves linearly to switch between a first position and a second position. When the baffle 34 is in the first position, the exhaust vent 123 is blocked. When the baffle 34 is in the second position, the exhaust vent 123 is opened. The exhaust vent opening and closing control system 3 has a simple and reasonable structure and can effectively realize the opening and closing of the exhaust vent 123.

[0047] like Figure 3 As shown, the exhaust vent opening and closing control system 3 can be arranged between the rear side plate of the inner cavity 11 and the outer shell 12, that is, the exhaust vent opening and closing control system 3 and the circulating air component are arranged on the rear side of the cooking cavity 111 at the same time.

[0048] The power component of the exhaust vent opening and closing control system 3 may include a motor, for example. To distinguish it from the motor in the circulating air component below, the motor of the exhaust vent opening and closing control system 3 is defined as the first motor 31, and the motor in the circulating air component is defined as the second motor 44. Figure 3 As shown, a first motor 31 is mounted on a motor bracket 35. The motor shaft of the first motor 31 passes through the motor bracket 35, and a gear 32 is mounted on the motor shaft. The body of the first motor 31 and the gear 32 are located on opposite sides of the motor bracket 35. A rack drive rod 33 is mounted on the side of the motor bracket 35 where the gear 32 is located. The rack drive rod 33 has teeth along its length. The teeth of the rack drive rod 33 mesh with the gear 32, so that when the gear 32 rotates, the rack drive rod 33 moves laterally relative to the motor bracket 35, extending out of the motor bracket 35 or retracting into the motor bracket 35. The baffle 34 is connected to the end of the rack drive rod 33 that can extend out of the motor bracket 35, and the plate surface of the baffle 34 is arranged vertically. When the rack drive rod 33 extends out of the motor bracket 35, the baffle 34 is pushed into the exhaust port 123 to block the exhaust port 123, thereby preventing the smoke in the cooking chamber 111 from being discharged out of the exhaust port 123 through the hot air generating chamber 121. Figure 8 When the rack drive rod 33 is retracted into the motor bracket 35, the baffle 34 is simultaneously driven to withdraw from the exhaust port 123, so that the exhaust port 123 is opened, so that the steam generated during baking in the cooking cavity 111 can be discharged outward through the exhaust port 123, ensuring smooth cooking. Figure 7 .

[0049] Continue to combine Figures 6 to 8 The exhaust vent opening and closing control system 3 also includes a first trigger switch 36 and a second trigger switch (not shown in the figure). When the rack drive rod 33 drives the baffle 34 to move to the first position, the rack drive rod 33 triggers the first trigger switch 36, and the first trigger switch 36 sends a first signal to the first motor 31. The first motor 31 receives the first signal and stops rotating. When the rack drive rod 33 drives the baffle 34 to move to the second position, the rack drive rod 33 triggers the second trigger switch, and the trigger switch sends a second signal to the first motor 31. The first motor 31 receives the second signal and stops rotating. By setting the trigger switch, the position of the baffle 34 can be accurately determined and the motor can be automatically stopped. This not only improves the convenience of operation, but also avoids the possibility of human control errors or misjudgments that may cause the baffle 34 to improperly open or close the exhaust vent 123 or not close tightly.

[0050] It is understood that in addition to using a trigger switch to determine the position of the baffle 34, the position of the baffle 34 can also be determined by setting the activation time or number of revolutions of the motor. For example, if the activation time of the first motor 31 is set to 3 seconds, the movement distance of the baffle 34 coincidentally corresponds to the distance from the first position to the second position. When the smoke oven switches from cooking mode to smoking mode, the control system of the smoke oven sends a signal to the first motor 31. After 3 seconds of activation of the first motor 31, the baffle 34 moves from the second position to the first position, and the first motor 31 stops.

[0051] In some embodiments, as Figure 3 As shown, an air outlet 1211 is provided on one side of the cavity wall of the hot air generating cavity 121, and the air outlet 1211 is connected to one end of the exhaust channel 124, and the other end of the exhaust channel 124 forms an exhaust port 123; a baffle bracket 125 is provided at the other end of the exhaust channel 124, and the baffle bracket 125 has a through hole 1251 for connecting the exhaust channel 124 with the outside world, see Figure 8 .like Figure 4 As shown, a sealing ring 37 is provided between the baffle bracket 125 and the other end of the exhaust duct 124. The two sides (opposite end faces) of the sealing ring 37 in the axial direction are tightly fitted with the outer periphery of the through hole 1251 and the outer periphery of the exhaust port 123, respectively. A groove 371 is provided on the inner periphery of the sealing ring 37, and an opening 372 communicating with the groove 371 is provided on the side of the sealing ring 37 near the rack drive rod 33. The baffle 34 can enter and exit the sealing ring 37 through the opening 372 to block or open the through hole 1251 and the exhaust port 123. By providing the sealing ring 37, when the baffle 34 is in the first position, the through hole 1251 and the exhaust port 123 can be tightly sealed, preventing smoke from leaking between the baffle 34 and the baffle bracket 125, and ensuring a tight seal during blocking.

[0052] In some embodiments, as Figure 3 As shown, the circulating air assembly includes a heating device 41, circulating air blades 42, cold air blades 43, a second motor 44, and an inner liner 45. The heating device 41 is located near the rear wall of the cooking chamber 111. The circulating air blades 42 and cold air blades 43 are both mounted on the output shaft of the second motor 44. The inner liner 45 is located between the circulating air blades 42 and cold air blades 43 and, together with the rear wall of the cooking chamber 111, forms a hot air generation chamber 121. The heating device 41 and circulating air blades 42 are located within the hot air generation chamber 121, while the cold air blades 43 and the second motor 44 are located outside the hot air generation chamber 121. An air outlet 1211 is located on one side of the inner liner 45 and communicates with the exhaust port 123.

[0053] Continue to combine Figure 3A motor seat 46 is provided on the outside of the lining 45 and surrounds the lining 45. The second motor 44 is provided on the motor seat 46 and is located on the side of the motor seat 46 away from the lining 45. The cold air blades 43 are located between the motor seat 46 and the lining 45. The cold air blades 43 are used to dissipate heat for the second motor 44.

[0054] like Figure 3 As shown, the ventilation hole 112 includes an air outlet hole 1121 and an air inlet hole 1122 arranged around the air outlet hole 1121. When the first motor 31 starts to drive the circulation fan blade 42 to rotate, the circulation fan blade 42 sends the air in the hot air generating chamber 121 into the cooking chamber 111 through the air inlet hole 1122, and draws the air in the cooking chamber 111 into the hot air generating chamber 121 through the air outlet hole 1121, so that the air in the cooking chamber 111 and the hot air generating chamber 121 forms a circulating flow.

[0055] The circulating air component uses the circulating fan blades 42 to drive the air circulation between the cooking cavity 111 and the hot air generating cavity 121. For example, when the smoke oven is in baking mode, the smoking component 2 is not started, it does not generate smoke, and no smoke enters the cooking cavity 111. The exhaust vent opening and closing control system 3 opens the exhaust vent 123, and the circulating air component is started, and the hot air in the hot air generating cavity 121 is sent into the cooking cavity 111 through the air inlet 1122, and the food in the cooking cavity 111 is baked with hot air. The hot air that cools down the food after baking returns to the hot air generating cavity 121 through the air outlet 1121 for heating. This cycle allows heat to evenly penetrate into the food, thereby achieving cooking of the food in the cooking cavity 111. When the smoke oven is in the smoking mode, the smoke assembly 2 is started, and the smoke it generates enters the cooking cavity 111. The exhaust vent opening and closing control system 3 closes the exhaust vent 123. The circulating air assembly is started, and the circulating fan blades 42 draw the smoke from the smoked food in the cooking cavity 111 through the air outlet 1121 into the hot air generating cavity 121, and return it to the cooking cavity 111 through the air inlet 1122, so that the smoke continuously circulates in the cooking cavity 111 and the hot air generating cavity 121, so that the smoke evenly penetrates the food and facilitates the smoke generated by the smoke assembly 2 to continuously enter the cooking cavity 111. Figure 3 The direction of the arrow in the middle indicates the direction of hot air circulation and flue gas flow.

[0056] The smoke oven may be provided with a control panel (not shown) having a smoking function cooking menu and a baking function cooking menu. Depending on the cooking menu, the program automatically identifies the position of the control damper 34 and automatically controls the damper 34 to open or close the exhaust vent 123. For example, when the user selects the smoking function cooking menu, the smoke oven enters the smoking mode. The program automatically identifies the position of the damper 34. If the damper 34 is not in the first position, the program controls the damper 34 to move to the first position to close the exhaust vent 123. Simultaneously, the heating element 23 of the smoke assembly 2 is activated. The heating element 23 heats the smoking material 25 (e.g., sawdust) in the smoke box 21, carbonizing it to form smoke that enters the cooking chamber 111 and permeates the food. When the set working time countdown is about to end, the program automatically stops the heating element 23. At the end of the working time, the automatic smoke system component is activated, opening the exhaust vent 123 to exhaust the trace amount of smoke in the cooking chamber 111, thus completing the cooking process.
