Description

Technical Field

[0001] This utility model relates to the field of cooking devices, and more particularly to a cooking inner pot structure and a cooking device having the cooking inner pot structure. Background Technology

[0002] Ovens, oven-microwave ovens, steam ovens, and other cooking appliances with baking functions generally have a hot air circulation system installed on the rear side of the inner cavity to achieve circulating heating within the cavity and ensure uniform heating. For example, the Chinese invention patent "A Steam Oven and Its Exhaust Control Method" with patent number ZL202210040203.8 (authorization announcement number CN114468792A) is an example.

[0003] Furthermore, food produces fumes and odors during the baking process. Existing technologies address this issue by using a catalytic module to treat the gases produced during cooking. For example, Chinese utility model patent ZL202320075624.4 (authorization announcement number CN219206633U) discloses a baking-function cooking inner cavity structure and oven, including an inner cavity. A top heating pipe is installed on the inner top surface of the inner cavity, and a hot air fan is installed on the back plate. A hot air baffle is provided on the rear side of the inner cavity, with an air inlet and an air outlet. The hot air baffle and the back plate of the inner cavity form a hot air chamber. The fan blades of the hot air fan are located in the hot air chamber, and a back heating pipe is provided around the outer periphery of the fan blades. A high-temperature catalytic decomposition device for decomposing fumes is provided at the top of the inner cavity. The air outlet of the hot air baffle includes a first air outlet, and the air inlet of the high-temperature catalytic decomposition device is fluidly connected to the first air outlet of the hot air baffle.

[0004] A catalytic module is used to catalytically oxidize odorous gases and harmful gases such as CO and NO generated during cooking into non-toxic and odorless gases such as carbon dioxide and nitrogen. However, in addition to fumes and odorous gases, food cooking also produces aromatic gases, which enhance the flavor of dishes, especially foods with special aromas, through the stimulation and blending of these aromas. If these aromas are catalytically removed, the cooking effect will be reduced. Summary of the Invention

[0005] The first technical problem this invention aims to solve is to provide a deodorizing structure for cooking devices that offers good cooking results, in contrast to existing technologies.

[0006] The second technical problem to be solved by this utility model is to provide a deodorizing structure for cooking devices that has good cooking effect and is easy to control, in contrast to the prior art.

[0007] The third technical problem to be solved by this utility model is to provide a cooking device with the above-mentioned deodorizing structure in contrast to the prior art.

[0008] The technical solution adopted by this utility model to solve at least one of the above-mentioned technical problems is as follows: a cooking inner pot structure, including an inner pot, a hot air fan installed on the back plate of the inner pot, and a hot air baffle covering the inner surface of the back plate to form a hot air chamber, the fan blades of the hot air fan being located in the hot air chamber and surrounded by a heating tube, the hot air baffle having an air inlet facing the fan blades and an air outlet spaced circumferentially around the air inlet, characterized in that the hot air chamber is further provided with a catalytic module, at least two of which are rotatably arranged circumferentially outside the fan blades, and each catalytic module has at least two states: in the first state, a gap is formed between adjacent catalytic modules to allow the airflow from the fan blades to pass through; in the second state, the corresponding ends of adjacent catalytic modules are joined together to form a ring around the fan blades;

[0009] It also includes a transmission system, which includes a first transmission wheel, a second transmission gear, a third transmission gear, and a control mechanism for controlling the synchronous rotation of the second transmission gear and the first transmission wheel. The first transmission wheel is coaxially arranged with the fan blade, and the third transmission gear corresponds one-to-one with the catalytic module and is respectively installed on the corresponding catalytic module. Each third transmission gear meshes with the second transmission gear.

[0010] Furthermore, the second transmission gear is annular in shape, with its inner circumference concave inward to form an annular groove. The outer circumferential end of the first transmission wheel is fitted into this annular groove, and the two can slide relative to each other circumferentially.

[0011] The aforementioned control mechanism includes locking balls that can be rolled and fitted into the aforementioned annular groove, and guide notches corresponding to each locking ball. There is at least one locking ball, and when there are at least two locking balls, they are spaced apart along the annular groove.

[0012] The aforementioned guide notches are formed by the recesses of the first transmission wheel's surface along its length, and at least two guide notches are evenly spaced along the surface of the first transmission wheel. Each locking ball is confined within its corresponding guide notch. When the first transmission wheel rotates from the first end of each guide notch towards the second end, and each locking ball is positioned at the first end of its corresponding guide notch, the second transmission gear rotates synchronously with the first transmission wheel. Conversely, when the first transmission wheel rotates from the second end of each guide notch towards the first end, the second transmission gear does not rotate. This configuration achieves both a secure installation between the first and second transmission gears and allows the control mechanism to control the synchronous rotation between the second and first transmission gears.

[0013] Furthermore, each of the guide notches is triangular in shape and includes a long side and a short side extending along the length of the first transmission wheel's surface. The free end of the long side of each guide notch is the first end of the guide notch, and each locking ball can be clamped between the first end of the corresponding guide notch and the sidewall of the annular groove, so that the rotation of the first transmission wheel can drive the second transmission gear to rotate synchronously. The angle between the other end of the long side of each guide notch and the corresponding short side is the second end of the guide notch, and each locking ball can be limited in the second end of the corresponding guide notch, so that the first transmission wheel cannot drive the second transmission gear to rotate synchronously, and the guidance of each locking ball can make the first transmission wheel rotate more smoothly.

[0014] Furthermore, the second end of each guide notch is a right angle. This allows each locking ball to be more stably confined within the second end of its corresponding guide notch.

[0015] Furthermore, each of the aforementioned catalytic modules is block-shaped and rotates around its own central axis. In the second state, the catalytic modules are assembled into a ring. This ensures stable rotation of each catalytic module and allows for better catalytic decomposition of the airflow from the centrifugal fan blades in the second state.

[0016] Furthermore, in the first state, each catalytic module is evenly spaced circumferentially around the aforementioned fan blade, and each catalytic module is arranged radially along the fan blade. This allows the airflow from the centrifugal fan blade to pass more smoothly through the gaps between adjacent catalytic modules in the first state, thereby better preserving the aroma of the food and ensuring optimal cooking results.

[0017] Furthermore, each of the aforementioned catalytic modules includes a square shell and a catalytic block. The shell is hollow, forming a cavity inside. The size of the catalytic block matches the cavity and is housed within it.

[0018] Furthermore, the aforementioned catalyst block is perforated with catalytic channels, and the corresponding sidewalls of the shell along the extension direction of each catalytic channel are hollowed out, exposing each port of each catalytic channel. In the second state, the airflow from the fan blades passes through the catalytic channels of each catalyst block. This simplifies the internal structure of each catalytic module, and in the second state, allows the airflow to pass smoothly through each catalytic module for catalytic decomposition. Simultaneously, in the first state, it better prevents the airflow from the centrifugal fan blades from being catalytically decomposed by the catalytic modules.

[0019] Furthermore, the first drive wheel is positioned between the aforementioned hot air baffles, and a vent is provided on the first drive wheel that is opposite to the aforementioned air inlet. This avoids obstructing the airflow through the air inlet, thereby ensuring hot air circulation between the inner cavity of the inner liner and the hot air chamber, and also ensuring the deodorization effect of each catalytic module on the airflow.

[0020] Furthermore, it also includes an annular mounting plate fixed to the inner surface of the back plate. This mounting plate surrounds the fan blade with the fan blade as its center. Each catalytic module's housing has a first rotating shaft and a bushing on its front and rear ends. A second rotating shaft corresponding to each catalytic module is fixed to the mounting plate, and each second rotating shaft is inserted into its corresponding bushing. Each bushing can rotate relative to its corresponding second rotating shaft. The first rotating shaft, bushing, and second rotating shaft on each catalytic module are respectively arranged along the rotation axis of that catalytic module, and each third transmission gear is respectively mounted on the first rotating shaft of its corresponding catalytic module. This design ensures stable installation of each catalytic module and allows each catalytic module to rotate smoothly under the drive of the second transmission gears.

[0021] Furthermore, the heating tubes are positioned outside each catalytic module. This prevents the heating tubes from interfering with the airflow from the fan blades into the catalytic modules in the second state, while also promoting heating of the catalytic modules by the heating tubes, thereby ensuring the catalytic effect of each module.

[0022] The technical solution adopted to further solve the third technical problem mentioned above is: a cooking device, characterized in that it includes the cooking inner pot structure as described above.

[0023] Compared with existing technologies, the advantages of this invention are as follows: This invention has at least two catalytic modules rotatably arranged circumferentially outside the fan blades of the hot air blower. In the first state, the airflow from the fan blades can flow out through the gaps between adjacent catalytic modules, and the airflow is not catalytically decomposed, thus retaining the aroma of the airflow (such as the natural fragrance of food or the aroma of seasonings). In the second state, the airflow from the fan blades blows onto each catalytic module, and each catalytic module catalytically decomposes odor molecules (such as oil fume molecules) in the airflow from the centrifugal fan blades, thereby removing the odor from the airflow. Therefore, this invention can effectively remove odors from the airflow and effectively retain the aroma of food by rotating the catalytic modules according to cooking needs, thus ensuring the cooking effect.

[0024] Furthermore, this invention achieves synchronous rotation of each catalytic module through a transmission system, facilitating better switching between the first and second states. The first transmission wheel is coaxially aligned with the fan blades of the hot air blower, allowing the hot air blower motor to simultaneously drive the first transmission wheel, eliminating the need for a separate drive device and simplifying the internal structure of the cooking liner. In addition, a control mechanism controls the synchronous rotation of the second transmission gear and the first transmission wheel, thereby controlling the rotational and stationary states of each catalytic module, initiating the switching between the two states, and ensuring that each catalytic module stably maintains the desired state.

[0025] As can be seen, this utility model not only ensures the existing hot air circulation function, but also has a deodorizing function, effectively preserves the aroma of food, and ensures the cooking effect. Furthermore, the internal structure is simple and easy to control. Attached Figure Description

[0037] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0038] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Since the embodiments disclosed in this utility model can be arranged in different directions, these terms indicating direction are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0039] A cooking appliance (e.g., an oven, a steam oven, or a microwave oven) includes, for example, Figures 1-11 The cooking inner pot structure shown includes an inner pot (not shown), a hot air blower mounted on a back plate 1 of the inner pot, and a hot air baffle 2 covering the inner surface of the back plate 1 to form a hot air chamber 20. The fan blades 3 of the hot air blower are located in the hot air chamber 20 and are surrounded by heating elements (not shown). The hot air baffle 2 has air inlets 21 facing the fan blades 3 and air outlets 22 spaced circumferentially around the air inlets 21. The hot air chamber 20 also contains at least two catalytic modules 4, each rotatably arranged circumferentially outside the fan blades 3. Each catalytic module 4 has at least two states: in the first state, a gap is formed between adjacent catalytic modules 4 to allow airflow from the fan blades 3 to pass through; in the second state, the corresponding ends of adjacent catalytic modules 4 are joined together to form a ring surrounding the fan blades 3.

[0040] Furthermore, it also includes a transmission system, which comprises a first transmission wheel 5, a second transmission gear 6, a third transmission gear 7, and a control mechanism for controlling the synchronous rotation of the second transmission gear 6 and the first transmission wheel 5. The first transmission wheel 5 is coaxially arranged with the fan blade 3, and the third transmission gear 7 corresponds one-to-one with the catalytic module 4 and is respectively mounted on the corresponding catalytic module 4, with each third transmission gear 7 meshing with the second transmission gear 6.

[0041] As can be seen from the above, in this invention, at least two catalytic modules 4 are circumferentially arranged outside the fan blades 3 of the hot air blower. In the first state, the airflow from the fan blades 3 can flow out through the gaps between adjacent catalytic modules 4, and the airflow is not catalytically decomposed, thus retaining the aroma of the airflow (such as the aroma of food or the aroma of seasonings). In the second state, the airflow from the fan blades 3 blows onto each catalytic module 4, and each catalytic module 4 catalytically decomposes the odor molecules (such as oil fume molecules) in the airflow from the centrifugal fan blades 3, thereby removing the odor from the airflow. Therefore, this invention can switch the state of each catalytic module 4 by rotating it according to cooking needs, thus effectively removing odors from the airflow while effectively retaining the aroma of food, thereby ensuring the cooking effect. Furthermore, this invention uses a transmission system to achieve synchronous rotation of each catalytic module 4, facilitating better switching between the first and second states. In this design, the first drive wheel 5 is coaxially arranged with the fan blades 3 of the hot air blower. This allows the hot air blower motor to simultaneously drive the first drive wheel 5, eliminating the need for a separate drive mechanism and thus simplifying the internal structure of the cooking liner. Furthermore, a control mechanism controls the synchronous rotation of the second drive gear 6 and the first drive wheel 5, thereby controlling the rotation and stationary states of each catalytic module 4. This enables the switching between these two states and ensures that each catalytic module 4 remains stably in the desired state. Therefore, this invention, while maintaining the existing hot air circulation function, also has a deodorizing function, effectively preserving the aroma of food and ensuring optimal cooking results. Moreover, its internal structure is simple and easy to control.

[0042] Furthermore, the second transmission gear 6 is annular in shape, with its inner circumference concave in the radial direction to form an annular groove 60. The outer circumferential end of the first transmission wheel 5 is fitted into the annular groove 60, and the two can slide relative to each other in the circumferential direction. The control mechanism includes a locking ball 8 that is rollably fitted into the annular groove 60 and a guide notch 50 corresponding to the locking ball 8. There is at least one locking ball 8, and when there are at least two locking balls 8, they are evenly spaced along the annular groove 60. The aforementioned guide notch 50 is formed by a recess in the wheel surface of the first transmission wheel 5 along its length. At least two guide notches 50 are spaced apart along the wheel surface of the first transmission wheel 5. Each locking ball 8 is respectively positioned within its corresponding guide notch 50. When the first transmission wheel 5 rotates from the first end of each guide notch 50 towards the second end, and each locking ball 8 is located at the first end of its corresponding guide notch 50, the second transmission gear 6 rotates synchronously with the first transmission wheel 5. Conversely, when the first transmission wheel 5 rotates from the second end of each guide notch 50 towards the first end, the second transmission gear 6 does not rotate. This configuration achieves both a stable installation between the first transmission wheel 5 and the second transmission gear 6, and allows the control mechanism to control the synchronous rotation between the second transmission gear 6 and the first transmission wheel 5.

[0043] Furthermore, each of the aforementioned guide notches 50 is triangular in shape and includes a long side and a short side extending along the length of the wheel surface of the first transmission wheel 5. The free end of the long side of each guide notch 50 is the first end of the guide notch 50, and each locking ball 8 can be clamped between the first end of the corresponding guide notch 50 and the sidewall of the annular groove 60, so that the rotation of the first transmission wheel 5 can drive the second transmission gear 6 to rotate synchronously. The angle between the other end of the long side of each guide notch 50 and the corresponding short side is the second end of the guide notch 50, and each locking ball 8 can be limited in the second end of the corresponding guide notch 50, so that the first transmission wheel 5 cannot drive the second transmission gear 6 to rotate synchronously, and the guidance of each locking ball 8 allows the first transmission wheel 5 to rotate more smoothly. Preferably, the second end of each of the aforementioned guide notches 50 is a right angle, so that each locking ball 8 can be more stably limited in the second end of the corresponding guide notch 50.

[0044] Furthermore, each of the aforementioned catalytic modules 4 is block-shaped, with its own central axis as its rotational axis. In the second state, the catalytic modules 4 are assembled into a ring. This ensures stable rotation of each catalytic module 4 and allows for better catalytic decomposition of the airflow from the centrifugal fan blade 3 in the second state. Simultaneously, in the first state, each catalytic module 4 is evenly spaced circumferentially around the fan blade 3 and radially arranged. This allows the airflow from the centrifugal fan blade 3 to pass more smoothly through the gaps between adjacent catalytic modules 4 in the first state, thus better preserving the aroma of food and ensuring optimal cooking results.

[0045] Specifically, in this embodiment, each of the aforementioned catalytic modules 4 includes a square shell 40 and a catalytic block 41. The shell 40 is hollow, forming a cavity 400 inside. The size of the catalytic block 41 matches the cavity 400 and is housed within it. Furthermore, catalytic channels 410 are provided through the catalytic block 41, and the corresponding sidewalls of the shell 40 along the extending direction of each catalytic channel 410 are hollowed out, exposing each port of each catalytic channel 410. In the second state, the airflow from the fan blade 3 passes through the catalytic channels 410 of each catalytic block 41. This simplifies the internal structure of each catalytic module 4, and in the second state, allows the airflow to pass smoothly through each catalytic module 4 and be catalytically decomposed. Simultaneously, in the first state, it better prevents the airflow from the centrifugal fan blade 3 from being catalytically decomposed by each catalytic module 4.

[0046] Preferably, the first drive wheel 5 is disposed between the hot air baffle 2 and the hot air baffle 2, and the first drive wheel 5 has a vent 51 opposite to the air inlet 21. This avoids the first drive wheel 5 obstructing the air intake of the air inlet 21, thus ensuring the hot air circulation between the inner cavity of the inner liner and the hot air chamber 20, and also ensuring the deodorization effect of each catalytic module 4 on the airflow. In addition, the heating tube is disposed outside each catalytic module 4. In this way, in the second state, the heating tube can be prevented from interfering with the airflow of the fan blade 3 into each catalytic module 4, and at the same time, it can promote the heating of each catalytic module 4 by the heating tube, thereby ensuring the catalytic effect of each catalytic module 4.

[0047] Furthermore, it also includes an annular mounting plate 11 fixed to the inner surface of the back plate 1. The mounting plate 11 surrounds the fan blade 3 with the fan blade 3 as the center. The front and rear end faces of the housing 40 of each catalyst module 4 are respectively provided with a first rotating shaft 401 and a bushing 402. The mounting plate 11 is fixed with a second rotating shaft 111 corresponding to each catalyst module 4. Each second rotating shaft 111 is inserted into the corresponding bushing 402, and each bushing 402 can rotate relative to the corresponding second rotating shaft 111. The first rotating shaft 401, bushing 402, and second rotating shaft 111 on each catalyst module 4 are respectively arranged along the rotation center axis of the catalyst module 4, and each third transmission gear 7 is respectively installed on the first rotating shaft 401 of the corresponding catalyst module 4. On the one hand, it can realize the stable installation of each catalyst module 4, and on the other hand, it can make each catalyst module 4 rotate smoothly under the drive of the second transmission gear 6.
