DETAILED DESCRIPTION

[0055] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0056] See also Figure 1-2 This embodiment provides an integrated stove. The integrated stove is a kitchen appliance that integrates multiple functions such as a range hood, a gas stove, a disinfection cabinet, and a storage cabinet. It is also called an environmentally friendly stove or an integrated environmentally friendly stove in the industry. The integrated stove has the advantages of saving space, good fume extraction effect, energy saving, low consumption, and environmental protection. In this embodiment, the integrated stove includes a steam discharge mechanism 100, a stovetop 200, and a cooking utensil. In this embodiment, the cooking utensil is an utensil that can generate steam, such as a steam oven and a microwave oven. This embodiment takes the cooking utensil as an example for exemplary description.

[0057] The surface of the stove 200 is equipped with a gas stove, which can be used for various cooking methods such as boiling, cooking, frying, etc. It also has a multi-level fire adjustment function, which is convenient for adjusting the fire size and temperature according to cooking needs. Above the stove 200, that is, the top of the integrated stove, a powerful exhaust system and filtering device are configured, which can effectively absorb, filter and purify the generated oil smoke, smoke and odor. Through efficient filtering equipment, most harmful substances can be filtered out, reducing pollution to indoor air and ensuring the cleanliness and hygiene of the kitchen environment.

[0058] The steam oven is located below the stove 200. The steam oven includes a box body and an inner tank located in the box body. The inner tank has a steaming and baking cavity. Food that needs to be steamed and baked can be placed in the steaming and baking cavity, which can realize cooking methods such as quick steaming and water-replenishing steam tender baking.

[0059] The steam exhaust mechanism 100 is arranged in the stove top 200, and the steam exhaust structure 100 is connected to the inner pot in the box of the steam oven, and is used to discharge the steam in the inner pot to avoid excessive water vapor inside the inner pot, thereby ensuring the normal operation of the steam oven and the cooking quality of food. The steam exhausted by the steam exhaust structure 100 is generally absorbed and discharged by the powerful exhaust system on the top of the integrated stove.

[0060] See also Figure 3 In some embodiments, the steam exhaust structure 100 includes a steam outlet pipe 10 , a regulating component 20 and a driving component 30 .

[0061] The steam outlet pipe 10 is connected to the inner pot of the steam oven and is used to discharge the steam in the inner pot to avoid excessive water vapor inside the inner pot, thereby ensuring the normal operation of the steam oven and the cooking quality of food.

[0062] The regulating component 20 is movably arranged in a plane relative to the steam outlet pipe 10, and the movable plane is arranged at an angle relative to the axis of the steam outlet pipe 10, and the driving component 30 is transmission-connected to the regulating component 20 to drive the regulating component 20 to move in the movable plane. In this way, when the driving component 30 drives the regulating component 20 to move, it can move to the flow cross-section of the steam outlet pipe 10, thereby adjusting the size of the flow cross-section of the steam outlet pipe 10. At this time, the regulating component 20 can completely block the flow cross-section of the steam outlet pipe 10, partially block the flow cross-section of the steam outlet pipe 10, or do not block the flow cross-section of the steam outlet pipe 10.

[0063] In this embodiment, since the movable plane is set at an angle relative to the axis of the steam outlet pipe 10, and the flow cross section of the steam outlet pipe 10 is approximately perpendicular to its axis, the movable plane and the flow cross section of the steam outlet pipe 10 can be parallel, the movable plane and the flow cross section of the steam outlet pipe 10 can also be coplanar, and the movable plane and the flow cross section of the steam outlet pipe 10 can also be relatively inclined. In this way, the driving component 30 drives the adjustment component 20 to move on the movable plane, which can change the degree of shielding of the flow cross section of the steam outlet pipe 10 by the adjustment component 20, thereby adjusting the size of the flow cross section of the steam outlet pipe 10. Since the size of the flow cross section of the steam outlet pipe 10 is adjustable, the discharge amount of steam from the steam outlet pipe 10 can be adjusted according to different cooking modes and different cooking stages of the steam oven, thereby improving the cooking effect of the steam oven.

[0064] It can be understood that in the above-mentioned movable plane, which is set at an angle relative to the axis of the steam outlet pipe 10, and when the movable plane and the flow cross-section of the steam outlet pipe 10 are relatively inclined, the acute angle between the two can be 30°, 40°, 50°, 60° and 70°, etc. In addition, when the movable plane and the flow cross-section of the steam outlet pipe 10 are relatively inclined, the adjustment component 20 can adjust the size of the flow cross-section within a larger range to adapt to more different cooking needs.

[0065] When the movable plane is coplanar with the flow cross-section of the steam outlet pipe 10, the adjustment component 20 can directly act on the flow cross-section of the steam outlet pipe 10 to achieve fast and accurate adjustment. When the movable plane is parallel to the flow cross-section of the steam outlet pipe 10, the entire adjustment process of the adjustment component 20 is more stable, reducing the steam flow instability caused by angle changes.

[0066] In this embodiment, the angle between the movable plane and the axis of the steam outlet pipe 10 is preferably 90°, and the movable plane and the flow cross-section of the steam outlet pipe 10 are coplanar. On the one hand, considering the space inside the entire stove 200, the adjustment component 20 occupies a smaller space, which is convenient for the reasonable design of the internal space of the stove 200 and the distribution of other appliances.

[0067] On the other hand, by designing that the angle between the movable plane and the axis of the steam outlet pipe 10 is 90°, the steam will be guided by the regulating component 20 and dispersed in all directions, thereby ensuring that the steam can flow out evenly and avoiding the situation where the steam is too concentrated or too sparse in certain areas.

[0068] In some embodiments, the adjusting component 20 moves in a translational manner relative to the steam outlet pipe 10 within the movable plane, thereby adjusting the size of the flow cross-section of the steam outlet pipe 10. The adjusting component 20 moves to the flow cross-section of the steam outlet pipe 10 in a translational manner, and the driving component 30 drives the adjusting component 20 to move translationally relative to the steam outlet pipe 10 to block the flow cross-section of the steam outlet pipe 10. In this embodiment, the translation method allows more precise control of the flow cross-section size of the steam outlet pipe 10. Because the translational motion is linear, the adjusting component 20 can be accurately moved to the desired position, thereby accurately adjusting the size of the flow cross-section.

[0069] In some other embodiments, the adjusting component 20 rotates relative to the steam outlet pipe 10 in a rotational manner within the movable plane, thereby adjusting the size of the flow cross-section of the steam outlet pipe 10. The adjusting component 20 moves to the flow cross-section of the steam outlet pipe 10 by rotating. Specifically, the adjusting component 20 rotates under the action of the driving component 30, and the rotation method can adapt to steam outlet pipes 10 of different shapes and sizes. By adjusting the rotation angle of the adjusting component 20, the size of the flow cross-section can be flexibly controlled.

[0070] Furthermore, when the adjusting component 20 rotates relative to the steam outlet pipe 10 in a rotational manner within the movable plane, the rotation axis of the adjusting component 20 can be coaxial with the axis of the steam outlet pipe 10, or the rotation axis of the adjusting component 20 can be parallel to the axis of the steam outlet pipe 10.

[0071] If the rotation axis of the adjusting component 20 is parallel to the axis of the steam outlet pipe 10, that is, the rotation axis of the adjusting component 20 deviates from the axis of the steam outlet pipe 10, then when the adjusting component 20 rotates, the position of the flow cross-section of the steam outlet pipe 10 is different, thereby adjusting the size of the flow cross-section of the steam outlet pipe 10. On the other hand, when the rotation axis of the adjusting component 20 is parallel to the axis of the steam outlet pipe 10, especially when the rotation axis of the adjusting component 20 is located outside the steam outlet pipe 10, it is convenient to inspect and maintain its rotating shaft.

[0072] When the rotation axis of the adjusting component 20 is coaxial with the axis of the steam outlet pipe 10, the position of the adjusting component 20 relative to the flow cross-section of the steam outlet pipe 10 is different when the adjusting component 20 rotates, thereby adjusting the size of the flow cross-section of the steam outlet pipe 10. For example, when the flow cross-section of the steam outlet pipe 10 is rectangular and the projection of the adjusting component 20 on the flow cross-section is fan-shaped, the adjusting component 20 will cover different positions of the flow cross-section of the steam outlet pipe 10 at different rotation angles. On the other hand, when the rotation axis of the adjusting component 20 can be coaxial with the axis of the steam outlet pipe 10, that is, the adjusting component 20 mainly adjusts the size of the flow cross-section of the steam outlet pipe 10 by rotating in the steam outlet pipe 10, since the adjusting component 20 occupies a smaller space in the stove 200, the internal space design of the stove 200 is more flexible.

[0073] See also Figure 3-5 In some embodiments, the adjustment component 20 includes a rotating member 21, a fixing member 22, and an adjusting member 23. Observed along the axial direction of the steam outlet pipe 10, the rotating member 21 is disposed at the periphery of the steam outlet pipe 10 and can rotate relative to the steam outlet pipe 10. The rotating member 21 has a first strip guide groove 21a. The first strip guide groove 21a can be a through groove or a blind groove. It can be specifically set according to actual conditions. In this embodiment, the first strip guide groove 21a is a through groove, which is convenient for users to observe the first strip guide groove 21a. The driving component 30 is in transmission connection with the rotating member 21 to drive the rotation of the rotating member 21.

[0074] The fixing member 22 is fixed relative to the steam outlet pipe 10. For example, the fixing member 22 and the steam outlet pipe 10 can be welded, bolted, or integrally formed. No specific explanation is given here and can be selected according to actual process conditions. The fixing member 22 has a second strip guide groove 22a corresponding to the first strip guide groove 21a. The second strip guide groove 22a can be a through groove or a blind groove, and can be set according to actual conditions.

[0075] Among them, the length direction of the second strip guide groove 22a is set at an angle with the length direction of the corresponding first strip guide groove 21a, and the connecting line at both ends of the second strip guide groove 22a can be an arc or a straight line. Therefore, in this embodiment, the connecting line at both ends of the second strip guide groove 22a is at an angle with the connecting line at both ends of the corresponding first strip guide groove 21a. It should be understood that the length direction of the second strip guide groove 22a is unchanged, and the direction of the connecting line at both ends of the first strip guide groove 21a changes with the rotation of the rotating member 21. Therefore, the angle between the length direction of the second strip guide groove 22a and the length direction of the corresponding first strip guide groove 21a can be 0°, 5°, 10°, 20° and 30°, etc., and as the rotating member 21 rotates, the degree of the angle also changes.

[0076] The adjusting member 23 is arranged between the rotating member 21 and the fixed member 22, and a first guide portion 23a penetrating the first strip guide groove 21a is protruded on the surface facing the rotating member 21, and a second guide portion 23b penetrating the second strip guide groove 22a is protruded on the surface facing the fixed member 22. During the rotation of the rotating member 21, the position change of the first strip guide groove 21a will drive the first guide portion 23a to move, and the adjusting member 23 also moves with the movement of the first guide portion 23a. However, in this process, the second guide portion 23b is limited by the second strip guide groove 22a, so the adjusting member 23 moves translationally relative to the second strip guide groove 22a. With the first guide portion 23a penetrating in the first strip guide groove 21a and the second guide portion 23b penetrating in the second strip guide groove 22a, the adjusting member 23 can accurately move along a predetermined trajectory when the rotating member 21 rotates. This design ensures that the movement of the adjusting member 23 is both stable and accurate, avoiding performance degradation or structural damage caused by inaccurate movement. During the translation process, the adjusting member 23 covers different areas of the flow cross section of the steam outlet pipe 10, thereby achieving the size adjustment of the flow cross section of the steam outlet pipe 10. Since the fixing member 22 is fixed, and the corresponding second strip guide groove 22a is also fixed, the second strip guide groove 22a plays a positioning and guiding role for the adjusting member 23, so that the adjusting member 23 translates relatively smoothly, thereby smoothly adjusting the size of the flow cross section of the steam outlet pipe 10, which helps to reduce the pressure and temperature fluctuations in the steam oven inner tank, thereby reducing the thermal stress and mechanical stress of the equipment. This can reduce the wear and failure of the equipment and extend its service life.

[0077] See also Figure 9-10 When the rotating member 21 rotates, the angle between the second strip guide groove 22a and the first strip guide groove 21a changes, so as to drive the adjusting member 23 to adjust the flow cross-section of the steam outlet pipe 10.

[0078] See also Figure 4-5, there are multiple adjusting members 23, and the multiple adjusting members 23 are arranged circumferentially along the axis of the steam outlet pipe 10. The specific number of the adjusting members 23 can be two, three, four, five, six and eight, etc. It can be understood that when the shape and size of the adjusting members 23 are consistent, when the number is larger, during the movement of the adjusting members 23, the size of the flow cross-section of the steam outlet pipe 10 can be adjusted more quickly, and in order to make the overall force of the rotating member 23 uniform, the multiple adjusting members 23 are evenly arranged circumferentially along the axis of the steam outlet pipe 10, and when there are multiple adjusting members 23, correspondingly, the number of the first strip guide groove 21a and the second strip guide groove 22a are both multiple, and are arranged one-to-one with the adjusting members 23.

[0079] Based on the previous embodiment, please continue to refer to Figure 4-5 The adjusting member 23 is plate-shaped, and each adjusting member 23 includes a first plate portion 231 and a second plate portion 232. The first guide portion 23a and the second guide portion 23b are respectively arranged on two opposite surfaces of the first plate portion 231. In this embodiment, the two surfaces are the upper surface and the lower surface of the first plate portion 231. When the rotating member 21 is located above the adjusting member 23 and the fixing member 22 is located below the adjusting member 23, the first guide portion 23a is located on the upper surface of the first plate portion 231, and the second guide portion 23b is located on the lower surface of the first plate portion 231. Conversely, the first guide portion 23a is located on the lower surface of the first plate portion 231, and the second guide portion 23b is located on the upper surface of the first plate portion 231.

[0080] The second plate portion 232 and the first plate portion 231 can be fixedly connected, specifically, they can be connected as one piece, or they can be connected by bolts, or they can be bonded by glue, and they extend from the first plate portion 231 to the axis of the steam outlet pipe 10. The second plate portion 232 includes two abutting edges 232a arranged opposite to each other. Along the direction close to the axis of the steam outlet pipe 10, the spacing between the two abutting edges 232a gradually decreases, and the abutting edge 232a is used to abut with the abutting edge 232a of the adjacent second plate portion 232.

[0081] The abutment edge 232a is a plane. In the present embodiment, when the driving assembly 30 drives the rotating member 23 to rotate and the adjusting member 23 translates along the second strip guide groove 22a, the abutment edge 232a of the second plate portion 232 always abuts against the abutment edge 232a of the adjacent second plate portion 232. In this way, steam can be prevented from flowing out from the abutment edges 232a of the two adjacent second plate portions 232, and it is easier to calculate the steam flow rate through the flow section so as to control the steam discharge amount.

[0082] Furthermore, when the driving assembly 30 drives the rotating member 23 to rotate and the adjusting member 23 translates along the second strip guide groove 22 a , the plurality of adjusting members 23 have a fully open position, a fully closed position and an intermediate position.

[0083] See also Figure 6 At this time, the multiple adjustment members 23 are in the fully closed position, and the abutting edge 232a is completely abutted against the abutting edge 232a of the adjacent second plate portion 232. At this time, the steam outlet pipe 10 has a minimum flow cross-section.

[0084] See also Figure 7 At this time, the multiple adjustment members 23 are in the middle position, and the abutting edge 232a partially abuts against the abutting edge 232a of the adjacent second plate portion 232. At this time, the flow cross-section of the steam outlet pipe 10 is between the maximum flow cross-section and the minimum flow cross-section.

[0085] See also Figure 8 At this time, the multiple adjustment members 23 are in the fully open position, and the abutting edge 232a is staggered or partially abutted with the abutting edge 232a of the adjacent second plate portion 232. At this time, the steam outlet pipe 10 has a maximum flow cross-section.

[0086] In this embodiment, when the second guide portion 23b is located at the end of the second strip guide groove 22a, the multiple adjustment members 23 are in the fully open position; when the second guide portion 23b is located in the middle of the second strip guide groove 22a, the multiple adjustment members 23 are in the fully closed position; when the second guide portion 23b is located at the end and the middle of the second strip guide groove 22a, the multiple adjustment members 23 are in the middle position. It can be understood that the middle position is not fixed and is determined according to the position of the second guide portion 23b in the second strip guide groove 22a.

[0087] See also Figure 11-12 In some embodiments, the regulating component 20 is located at the outlet side or the inlet side of the steam outlet pipe 10, or the regulating component 20 is located at the middle section of the steam outlet pipe 10. The specific position of the regulating component 20 can be set according to actual conditions, but it can be understood that the inlet side of the steam outlet pipe 10 is generally penetrated to the inner pot of the steam oven, so if the regulating component 20 is set in the inner pot, it will occupy the space of the inner pot. Therefore, in general, the regulating component 20 is located at the outlet side or the middle section of the steam outlet pipe 10. In this embodiment, the regulating component 20 is located at the middle section of the steam outlet pipe 10, that is, in the middle of the stove 200. In this way, the regulating component 20 can be hidden in the middle of the stove 200 and will not occupy the surface of the stove 200. Therefore, the stove 200 looks neat and generous from the appearance.

[0088] In some embodiments, the driving assembly 30 includes a driving member and a transmission member 31, and the transmission member 31 is in transmission connection with the driving member and the adjusting assembly 20, and the transmission member 31 includes at least one of a gear, a lead screw, a synchronous belt, a rack, and a toothed chain.

[0089] That is, in this embodiment, the regulating assembly 20 is driven to rotate by an electric control method, and the rotation angle of the regulating assembly 20 can be controlled in cooperation with the control module, so as to remotely control the size of the flow cross section of the steam outlet pipe 10 .

[0090] See also Figure 3-5 Specifically, the driving member includes a motor, the transmission member 31 includes a gear, and the adjustment component 20 has a transmission tooth 24, which is meshed with the gear. The motor drives the gear to rotate, and the gear drives the transmission tooth 24 to rotate, thereby driving the adjustment component 20 to rotate. Specifically in this embodiment, the transmission tooth 24 is located on the circumferential side wall of the rotating member 21, that is, it drives the rotating member 21 to rotate, thereby driving multiple adjustment members 23 to move synchronously, thereby adjusting the size of the flow cross section of the steam outlet pipe 10. The transmission mode of the meshing connection between the gear and the transmission tooth 24 makes the rotation of the rotating member 21 relatively stable. In addition, the transmission ratio of the gear transmission is constant, and the accurate transmission ratio can be maintained for a long time, which is convenient for accurately adjusting the size of the flow cross section of the steam outlet pipe 10.

[0091] On the other hand, the gear transmission method has a more compact structure and occupies less space, which helps to save the overall space of the stove 200 and makes the design more flexible.

[0092] In some implementations, when the transmission member 31 is a synchronous belt, transmission teeth need to be set on the circumferential side walls of the rotating member 21. The synchronous belt connects the transmission teeth and gears on the circumferential side walls of the rotating member 21, and the gears are connected to the motor transmission. In this way, the rotation of the rotating member 21 can also be realized.

[0093] In addition, when the transmission member 31 is a lead screw, the slider on the lead screw is connected to the adjustment component 20. At this time, the adjustment component 20 moves relative to the steam outlet pipe 10 in a translational manner within the active plane. The lead screw is driven to rotate by the motor, driving the slider to move, thereby driving the adjustment component 20 to translate, so as to adjust the size of the flow cross-section of the steam outlet pipe 10.

[0094] In some other embodiments, when the transmission member 31 is a rack, transmission teeth can be set on the peripheral side wall of the rotating member 21, and the rack is meshingly connected with the transmission teeth. The rack is driven to move by a motor, which can drive the rotating member 21 to rotate, thereby driving multiple adjustment members 23 to move synchronously, thereby adjusting the size of the flow cross-section of the steam outlet pipe 10.

[0095] It is understandable that the adjustment assembly 20 may also be driven to move by other transmission methods, which will not be described in detail here.

[0096] See also Figure 10-12 The steam exhaust structure 100 also includes a steam exhaust box body 40 and a shielding member 50 .

[0097] The exhaust box body 40 is located on the stove 200 and defines an exhaust cavity 40a. The exhaust cavity 40a is formed with an exhaust port 40b on the upper surface of the exhaust box body 40. The exhaust port 40b should not be protruding from the upper surface of the stove 200. In this way, the upper surface of the stove 200 is a whole plane, which looks neat, generous and beautiful. The side wall of the exhaust box body 40 is provided with a vent hole connected to the stove 200, which can dissipate the heat in the stove 200 in time, maintain the stable operation of the integrated stove, and prevent safety problems caused by overheating. In addition, when the flame heats the food, the carbon dioxide produced needs to combine with a certain amount of oxygen to be completely burned. The vent hole allows an appropriate amount of oxygen to enter the combustion area, thereby ensuring that the flame burns more stably and improving the cooking effect.

[0098] The shielding member 50 is connected to the exhaust box body 40 and partially blocks the exhaust port 40b, wherein the steam outlet pipe 10 is arranged in the exhaust cavity 40a, and the steam discharged from the steam outlet of the steam outlet pipe 10 first enters the exhaust cavity 40a, and then is discharged to the outside of the stove 200 through the exhaust port 40b at the upper end. The steam outlet of the steam outlet pipe 10 is arranged opposite to the shielding member 50, so that the steam passing through the steam outlet pipe 10 will be blocked by the shielding member 50, which can avoid direct steam injection, thereby improving safety. On the other hand, it can also prevent foreign matter from falling directly into the steam outlet pipe 10 through the steam outlet of the steam outlet pipe 10, so as to avoid foreign matter blocking the flow of steam, resulting in the inability to discharge steam normally.

[0099] It can be understood that in order to enable the steam discharged from the steam outlet pipe 10 to be quickly absorbed by the exhaust system on the top of the integrated stove, the steam exhaust box 40 is designed to be located on the stove top 200 close to the air outlet of the exhaust system. In this way, the exhaust system can absorb the steam in time to prevent steam from hurting people.
