Description

Technical Field

[0002] This section merely provides background information related to the present disclosure and is not necessarily prior art.

[0003] The combined cooking equipment is usually equipped with a box, a cooking table, a heating device and an oil fume suction device. The cooking table cooperates with the box, the oil fume suction device is arranged in the box and communicated with the top of the cooking table, the heating device is arranged in the box or on the cooking table, and the heating device is arranged corresponding to the cooking position of the cooking table. The oil fume suction device usually includes a fan, a volute and an exhaust pipe. The air inlet of the volute is communicated with the top of the cooking table, and the air outlet of the volute is communicated with the exhaust pipe. When cooking food, the cooker is placed on the cooking position, the heating mechanism heats the cooker to cook the food, and the fan is started to generate negative pressure in the volute, so that the oil fume above the cooking table enters the exhaust pipe through the air inlet, the inside of the volute and the air outlet in turn, thereby improving the air quality during cooking.

[0004] In the prior art, the air inlet of the oil fume extraction device is set on a plane flush with the cooking table, next to the cooker, and the position of the air inlet is fixed, so the oil fume extraction effect is not ideal. In addition, due to the large height difference between the air inlet and the cooker, some oil fume cannot be sucked into the interior of the volute, and spreads into the kitchen, affecting the user experience. Summary of the invention

[0005] The purpose of the present invention is to at least solve the problem of unsatisfactory fume absorption effect caused by the fixed position of the air inlet in the prior art. This purpose is achieved through the following technical solutions:

Under the action of the oil fume suction device of the combined cooking device, oil fume enters from the air intake port 11 for discharge treatment. An air intake mechanism 2 and a driving mechanism 3 are provided at the frame 1. Under the action of the driving mechanism 3, the air intake port 11 can be in an open state when oil fume suction is required, and in a sealed state when oil fume suction is not required, so as to prevent foreign matter from entering the interior of the combined cooking device from the air intake port 11. The driving mechanism 3 drives the air intake mechanism 2 to rotate to switch between a first position and a second position. In the first position, the air intake mechanism 2 seals the air intake port 11. In the second position, the air intake mechanism 2 exposes the air intake port 11, and the air intake mechanism 2 is connected with the air intake port 11 to form a channel for the flow of oil fume, so that the oil fume can enter the air intake port 11. After the air inlet assembly rotates, the air inlet 11 is exposed. Compared with the prior art, the position of the air inlet 11 is raised and closer to the area where oil smoke is concentrated, shortening the height difference between the air inlet 11 and the cooker, improving the efficiency of oil smoke absorption, improving the overall air quality in the kitchen during cooking, and improving the user experience.

[0077] In some embodiments of the present invention, the driving mechanism 3 can be connected to the frame 1, or to the box 1 or the fan device 7 of the combined cooking device. In one embodiment, the driving mechanism 3 is connected to the frame 1 to reduce the transmission distance between the driving mechanism 3 and the air intake mechanism 2, thereby reducing the size of the driving mechanism 3 and making the structure more compact.

[0078] In some embodiments of the present invention, the air inlet mechanism 2 can rotate under the action of the driving mechanism 3 so that the air inlet mechanism 2, the air inlet 11 and the oil smoke are connected, and there are several settings as follows. The first one is that the air inlet mechanism 2 includes a flat plate and an arc plate, the arc plate and the flat plate form a semi-cylindrical area, and the arc plate is evenly distributed with through holes so that the oil smoke can enter. In the first position, the flat plate is flush with the cooking table 5 of the cooking combination device to seal the air inlet 11, and the arc plate is located inside the cooking combination device. Under the drive of the driving mechanism 3, the air inlet mechanism 2 rotates 180° to the second position, at which time the arc plate exposes the air inlet 11, and the flat plate is located inside the cooking combination device. The second type, the air inlet mechanism 2 includes a first arc plate and a second arc plate, the cross-sections of the first arc plate and the second arc plate are both semicircular, wherein the second arc plate is evenly distributed with through holes to allow oil smoke to enter, the two arc plates are concentrically arranged, in the first position, the first arc plate and the second arc plate are both exposed to the air inlet 11, the first arc plate is located above the second arc plate, the first arc plate seals the air inlet 11, under the drive of the driving mechanism 3, the first arc plate rotates 180° to the second position, at this time, the second arc plate is exposed, and the first arc plate is located inside the combined cooking device. The third type is that the air inlet mechanism 2 includes a first air inlet cover 21 and a second air inlet cover 22 of the same structure, and the first air inlet cover 21 and the second air inlet cover 22 are both connected to the driving mechanism 3. In the first position, the first air inlet cover 21 and the second air inlet cover 22 are both located inside the combined cooking device. Under the drive of the driving mechanism 3, the first air inlet cover 21 and the second air collection cover rotate 90 degrees in opposite directions to the second position, at which time the first air inlet cover 21 and the second air inlet cover 22 are both exposed to the air inlet 11. Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, in one embodiment, the air inlet mechanism 2 adopts a third setting mode.

[0079] In some embodiments of the present invention, there are several configurations for driving the air inlet mechanism 2. In the first configuration, two driving members are provided, and the two driving members are used to drive the first air inlet hood 21 and the second air inlet hood 22 to rotate respectively. In the second configuration, one driving member is provided, and the synchronous rotation of the first air inlet hood 21 and the second air inlet hood 22 is achieved through the one driving member. In the second configuration, the driving member can drive the first air inlet hood 21 to rotate, and then the first air inlet hood 21 drives the second air inlet hood 22 to rotate. It can also be configured so that the driving force of the driving member is simultaneously transmitted to the first air inlet hood 21 and the second air inlet hood 22 through a transmission assembly. The transmission assembly includes an active member and a driven member cooperating with the active member. The first air inlet hood 21 is connected to the active member, and the second air inlet hood 22 is connected to the driven member. The driving member drives the active member to move to drive the first air inlet hood 21 to rotate, and the active member drives the driven member to move to drive the second air inlet hood 22 to rotate. Figure 1 , Figure 4 and Figure 8 As shown, in one embodiment, the driving mechanism 3 adopts the second setting mode, and the rotation of the first air inlet hood 21 and the second air inlet hood 22 is realized by the transmission assembly. Specifically, the driving mechanism 3 includes a driving assembly 31, a first transmission assembly 32, and a second transmission assembly 33 cooperating with the first transmission assembly 32. The driving assembly 31 is connected to the frame 1, the second air inlet hood 22 is connected to the driving assembly 31 through the first transmission assembly 32, and the first air inlet hood 21 is connected to the first transmission assembly 32 through the second transmission assembly 33. The first transmission assembly 32 and the second transmission assembly 33 can be connected to the frame 1, or the first transmission assembly 32 can be connected to the second air inlet hood 22, and the second transmission assembly 33 can be connected to the first air inlet hood 21. In one embodiment, the first transmission assembly 32 and the second transmission assembly 33 are both connected to the frame 1. In this embodiment, the synchronous rotation of the first air inlet hood 21 and the second air inlet hood 22 is achieved by a driving component 31, a first transmission component 32 and a second transmission component 33. Compared with the method of providing two driving components 31 to respectively drive the first air inlet hood 21 and the second air inlet hood 22, the number of parts of the air inlet device is reduced, and the synchronous rotation of the first air inlet hood 21 and the second air inlet hood 22 can also be ensured.

[0080] In some embodiments of the present invention, Figure 1 , Figure 2 , Figures 4 to 9 As shown, the first transmission assembly 32 includes a first gear 321, which is rotatably connected to the frame 1, and the first gear 321 is connected and driven by the driving assembly 31. The second air inlet hood 22 is connected to the first gear 321. The driving assembly 31 transmits power to the first gear 321, and the first gear 321 transmits power to the second air inlet hood 22. The rotating shafts of the first gear 321 and the second air inlet hood 22 can be set to be the same or different. The second transmission assembly 33 includes a second gear 331, which is rotatably connected to the frame 1, and the second gear 331 is meshed with the first gear 321. The first gear 321 transmits power to the second air inlet hood 22 and also transmits power to the second gear 331. The second gear 331 transmits power to the first air inlet hood 21, and the first air inlet hood 21 and the second air inlet hood 22 are synchronously rotated by the meshing first gear 321 and the second gear 331. The first gear 321 and the second gear 331 are in an external meshing form. The first gear 321 and the second gear 331 rotate in opposite directions, driving the first air inlet cover 21 and the second air inlet cover 22 to rotate in opposite directions. The first gear 321 and the second gear 331 are standard involute gears.

[0081] In some embodiments of the present invention, Figure 1 , Figure 2 , Figures 4 to 9 As shown, when the first gear 321 and the second gear 331 are used to directly drive the first air inlet hood 21 and the second air inlet hood 22, there may be interference with other structures. Therefore, the first transmission assembly 32 also includes a first connecting member 322, one end of the first connecting member 322 is eccentrically connected to the first gear 321, and the other end of the first connecting member 322 is connected to the frame 1 at different positions of the second air inlet hood 22. The connection between the frame 1 and the second air inlet hood 22, the connection between the second air inlet hood 22 and the first connecting member 322, the connection between the first connecting member 322 and the first gear 321, and the connection between the first gear 321 and the frame 1 can be regarded as a deformation of a four-bar mechanism, which can be a crank-rocker mechanism, in which the first gear 321 is a crank and the second air inlet hood 22 is a rocker, or a double rocker mechanism, in which the first gear 321 and the second air inlet hood 22 are both rockers.

[0082] In some embodiments of the present invention, Figure 1 , Figure 2 , Figures 4 to 9 As shown, similar to the structure of the first transmission assembly 32, the second transmission assembly 33 also includes a second connecting member 332, one end of the second connecting member 332 is eccentrically connected to the second gear 331, and the other end of the second connecting member 332 is connected to the frame 1 at different positions of the first air inlet cover 21. The connection between the frame 1 and the first air inlet cover 21, the connection between the first air inlet cover 21 and the second connecting member 332, the connection between the second connecting member 332 and the second gear 331, and the connection between the second gear 331 and the frame 1 can be regarded as a deformation of a four-bar mechanism, which can be a crank-rocker mechanism, the second gear 331 is a crank, and the first air inlet cover 21 is a rocker, or a double rocker mechanism, the second gear 331 and the first air inlet cover 21 are rockers. By providing the first connecting member 322 and the second connecting member 332, it is possible to prevent the first air inlet cover 21 and the second air inlet cover 22 from interfering with other structures during rotation. However, in order to avoid the first connecting member 322 and the second connecting member 332 from interfering with each other in the process of driving the first air inlet cover 21 and the second air inlet cover 22 to rotate, the structures are slightly different. The first connecting member 322 is straight, and the second connecting member 332 includes a plurality of bending sections to avoid the first connecting member 322.

[0083] In some embodiments of the present invention, according to the above, the area included in the air inlet mechanism 2 is a semicircular area. When the first air inlet cover 21 and the second air inlet cover 22 are provided, the first air inlet cover 21 and the second air inlet cover 22 respectively include a quarter-circular area. Figure 3As shown, the first air inlet hood 21 includes a first connecting plate 211 and a second connecting plate 212. The other ends of the frame 1 and the second connecting member 332 are rotatably connected to different positions of the first connecting plate 211, respectively. The first connecting plate 211 is provided with first ventilation holes, and the second connecting plate 212 is connected to the first connecting plate 211. The first connecting plate 211 is an arc-shaped plate, and the second connecting plate 212 is a flat plate. The first connecting plate 211 and the second connecting plate 212 form a 90° fan-shaped area, that is, the cross-section of the first air inlet hood 21 is a quarter of the circular arc area. In the first position, the second connecting plate 212 is located at the air inlet 11, flush with the cooking table 5 of the combined cooking device. Driven by the driving mechanism 3, the second connecting plate 212 rotates toward the second air inlet hood 22, so that the first connecting plate 211 rises from the inside of the combined cooking device to expose the air inlet 11. As shown Fig.11 As shown, during the rotation of the first air inlet cover 21, the gap between the first connecting plate 211 and the cooking table 5 of the combined cooking device remains unchanged, thereby preventing foreign matter from entering the interior of the combined cooking device through the gap during the rotation.

[0084] In some embodiments of the present invention, Figure 3 and Fig.12 As shown, the second air inlet cover 22 has the same structure as the first air inlet cover 21. The second air inlet cover 22 includes a third connecting plate 221 and a fourth connecting plate 222. The other ends of the frame 1 and the first connecting member 322 are rotatably connected to different positions of the third connecting plate 221, respectively. The third connecting plate 221 is provided with second ventilation holes. The fourth connecting plate 222 is connected to the third connecting plate 221. The third connecting plate 221 is an arc-shaped plate, and the fourth connecting plate 222 is a flat plate. The third connecting plate 221 and the fourth connecting plate 222 form a 90° fan-shaped area, that is, the cross-section of the second air inlet cover 22 is a quarter of the arc area. In the first position, the fourth connecting plate 222 is located at the air inlet 11, as shown in FIG. Fig.10 As shown, the fourth connecting plate 222 is flush with the cooking table 5 of the combined cooking device. Under the drive of the driving mechanism 3, the fourth connecting plate 222 rotates in the direction of the second air inlet cover 22, so that the third connecting plate 221 rises from the inside of the combined cooking device to expose the air inlet 11. During the rotation of the second air inlet cover 22, the gap between the third connecting plate 221 and the cooking table 5 of the combined cooking device remains unchanged, so as to prevent foreign matter from entering the inside of the combined cooking device through the gap during the rotation. When the first air inlet cover 21 and the second air inlet cover 22 are both in the second position, the first ventilation hole on the first air inlet cover 21 and the second ventilation hole on the second air inlet cover 22 face the direction of the oil smoke, and two channels are formed between the outside world and the air inlet 11 for the oil smoke to flow, so as to facilitate the rapid absorption of the oil smoke. The first channel is the outside world - the first ventilation hole on the first air inlet cover 21 and the air inlet 11, and the second channel is the outside world - the second ventilation hole on the second air inlet cover 22 and the air inlet 11.

[0085] In some embodiments of the present invention, Figure 8 and Fig. 9 As shown, the first gear 321 is provided with a first broken tooth area 3211, and the first broken tooth area 3211 extends outward to form a first limiting surface 3212 and a second limiting surface 3213. In the first position, the first limiting surface 3212 is limitedly matched with the frame 1, and in the second position, the second limiting surface 3213 is limitedly matched with the frame 1. The circumference of the first gear 321 is an incomplete tooth structure. On the one hand, it prevents the continuous rotation of the motor from causing the first air inlet cover 21 and the second air inlet cover 22 to continue to rotate and interfere with each other and damage the air inlet device. Only the first gear 321 can be set to an incomplete tooth structure, and the second gear 331 can be a full tooth structure. When the position of the first gear 321 without a gear tooth is matched with the second gear 331, the second gear 331 does not rotate. Alternatively, both the first gear 321 and the second gear 331 can be set to an incomplete tooth structure. In order to ensure that the second air inlet cover 22 can stop moving after moving to the first position and the second position, a first limiting surface 3212 and a second limiting surface 3213 are also provided on the first gear 321. The first limiting surface 3212 and the second limiting surface 3213 are located in the first broken tooth area 3211 and are formed by extending outward from the first broken tooth area 3211. When the second air inlet cover 22 is in the first position, the first limiting surface 3212 is limitedly matched with the frame 1. When it is in the second position, the second limiting surface 3213 is limitedly matched with the frame 1. The first limiting surface 3212 and the second limiting surface 3213 limit the rotation range of the second air inlet cover 22 to improve the reliability of use.

[0086] In some embodiments of the present invention, Figure 8 and Fig. 9 As shown, in one embodiment, the second gear 331 is also configured as an incomplete tooth structure. The second gear 331 is meshed with the first gear 321. When the first gear 321 stops rotating, the second gear 331 will also stop rotating. However, in order to further increase the reliability during use, a third limiting surface 3312 and a fourth limiting surface 3313 are also provided on the second gear 331. The third limiting surface 3312 and the fourth limiting surface 3313 are located in the second broken tooth area 3311 and are formed by extending outward from the second broken tooth area 3311. When the first air inlet hood 21 is in the first position, the third limiting surface 3312 is limitedly matched with the frame 1. When the first air inlet hood 21 is in the second position, the fourth limiting surface 3313 is limitedly matched with the frame 1. The third limiting surface 3312 and the fourth limiting surface 3313 limit the rotation range of the first air inlet hood 21. In summary, in the first position, the first limiting surface 3212 and the third limiting surface 3312 are in limiting cooperation with the frame 1 , and in the second position, the second limiting surface 3213 and the fourth limiting surface 3313 are in limiting cooperation with the frame 1 .

[0087] In some embodiments of the present invention, Figure 4 , Figure 5 and Fig.10 As shown, the air intake device also includes a connecting rod 4 located between the first air intake cover 21 and the second air intake cover 22, and the connecting rod 4 is connected to the frame 1. In the first position, the first air intake cover 21, the connecting rod 4 and the second air intake cover 22 form a plane flush with the cooking table 5 of the combined cooking device to seal the air inlet 11. In the second position, the connecting rod 4 is located between the second connecting plate 212 and the fourth connecting plate 222, which plays a role in limiting excessive rotation of the first air intake cover 21 and the second air intake cover 22.

[0088] The following is a description of the working process of the air inlet device in the embodiment of the present application:

[0089] Starting process: the driving component 31 drives the first gear 321 to rotate, and the first gear 321 drives the second air inlet hood 22 to rotate through the first connecting member 322. At the same time, the first gear 321 drives the second gear 331 meshing therewith to rotate, and the second gear 331 drives the first air inlet hood 21 to rotate through the second connecting member 332, until the first limiting surface 3212 on the first gear 321 and the third limiting surface 3312 on the second gear 331 are limitedly matched with the frame 1 and abut against the frame 1, the driving component 31 stops outputting driving force, and the first air inlet hood 21 and the second air inlet hood 22 are in the second position.

[0090] Closing process: The driving component 31 drives the first gear 321 to move in the opposite rotation direction during the opening process, and the first gear 321 drives the second air inlet hood 22 to rotate through the first connecting member 322. At the same time, the first gear 321 drives the second gear 331 meshing therewith to rotate, and the second gear 331 drives the first air inlet hood 21 to rotate through the second connecting member 332, until the second limiting surface 3213 on the first gear 321 and the fourth limiting surface 3313 on the second gear 331 are limitedly matched with the frame 1 and abut against the frame 1, the driving component 31 stops outputting driving force, and the first air inlet hood 21 and the second air inlet hood 22 are in the first position.

[0091] like Fig.13 As shown, another embodiment of the present invention provides a combined cooking device, comprising:

[0092] Cooking station 5;

[0093] An air inlet device, which is any of the above technical solutions and is connected to the cooking table 5;

[0094] A box body 6, a cooking table 5 is arranged above the box body 6, and an air inlet device is arranged in the box body 6;

[0095] The fan device 7 is arranged below the air inlet device along the flow direction of the oil smoke.

[0096] The combined cooking device according to the embodiment of the present invention has the same advantages as the above-mentioned air intake device, which will not be described in detail here. The cooking table 5 is connected to the box body 6 to form a closed space. The air intake device and the fan device 7 are both arranged in the box body 6. The air intake device is connected to the cooking table 5, which is closer to the position of the cooker. Compared with the arrangement of arranging the air intake device in front of or above the user, the air intake device will not affect the user's cooking, and the air intake device is closer to the concentrated area of ​​​​oil smoke. During cooking, the cooking combination device is turned on, and the driving mechanism drives the air intake mechanism to rotate to the second position. The air intake mechanism is connected to the air inlet, which shortens the height difference between the air inlet and the cooker. Under the action of the air intake device, the oil smoke passes through the air intake mechanism and enters the fan device 7 for discharge.

[0097] The start-up of the air inlet device can be controlled through a linkage circuit with the start-up of the combined cooking device, or a separate switch button can be set for the air inlet device.

[0098] The above are only preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
