[0046] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0047] The air duct structure 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0048] Reference Figure 1 According to a first aspect of the present invention, the air duct structure 100 includes: an air outlet duct component 1 and an exhaust duct component 2.

[0049] Specifically, combined Figure 2 and Figure 3 The air outlet duct component 1 is limited to an air outlet duct 10 (combined with...) Figure 5 and Figure 11 Furthermore, the air outlet duct component 1 has an air inlet 11 and an air outlet 12. In this way, air can enter the air outlet duct 10 through the air inlet 11 and then be discharged through the air outlet 12.

[0050] The exhaust duct component 2 is connected to the outlet duct component 1, and the exhaust duct component 2 is located adjacent to the outlet 12. The exhaust duct component 2 defines an exhaust duct 20 (in conjunction with...). Figure 12 ), and the exhaust duct component 2 has an air inlet 21 (combined with Figure 7 ), steam inlet 22 and exhaust outlet 23 (combined) Figure 2 The air inlet 21 is connected to the air outlet duct 10. In this way, part of the air entering the air outlet duct 10 from the air inlet 11 can be discharged through the air outlet 12, and part of the air can enter the exhaust duct 20 through the air inlet 21 and then be discharged through the exhaust port 23.

[0051] Specifically, when the air duct structure 100 is applied to the cooking equipment 1000, the cooking equipment 1000 may have an exhaust port 201. Furthermore, the exhaust port 201 may be connected to the air inlet 11. In this way, the air discharged from the exhaust port 201 may enter the exhaust duct 10 through the air inlet 11. Part of the air may be discharged from the exhaust port 12, and another part of the air may enter the steam exhaust duct 20 through the air inlet 21. This can cool and condense the steam entering the steam exhaust duct 20 from the steam inlet 22. Finally, the cooled steam is discharged from the exhaust port 23. In this way, on the one hand, the amount of steam discharged into the room can be reduced, and on the other hand, the steam can be cooled to prevent users from being scalded and improve safety. This can solve the technical problems of large steam discharge and high steam temperature that easily scald users in related technologies.

[0052] According to the air duct structure 100 of the present invention, air can enter the air outlet duct 10 through the air inlet 11, a portion of the air can be discharged through the air outlet 12, and another portion of the air can enter the exhaust duct 20 through the air inlet 21. This can cool and condense the steam entering the exhaust duct 20 through the steam inlet 22. Finally, the cooled steam is discharged through the exhaust outlet 23. In this way, on the one hand, the amount of steam discharged into the room can be reduced, and on the other hand, the steam can be cooled to prevent users from being scalded and improve safety. This can solve the technical problems of large steam discharge and high steam temperature that easily scald users in related technologies.

[0053] The duct structure 100 according to an embodiment of the present invention can cool high-temperature steam and reduce steam emissions, has good safety, and can also improve user experience.

[0054] In some embodiments of the present invention, reference is made to... Figure 4 and Figure 5 The air inlet 11 and the air outlet 12 are arranged roughly vertically. This helps to reduce the length of the air duct structure 100, making the structure of the air duct structure 100 more compact and reducing the space occupied.

[0055] In some embodiments of the present invention, combined with Figure 5 The air outlet 12 can be configured to discharge air approximately tangentially along the air outlet duct 10. This tangential air discharge reduces duct resistance, thereby improving air utilization, optimizing duct performance, and enhancing airflow.

[0056] In some embodiments of the present invention, reference is made to... Figure 1 and Figure 3 The air inlet 21 can be connected to the air outlet 12, which makes it easier for the air in the air outlet duct 10 to be diverted through the air inlet 21 and the air outlet 12 respectively.

[0057] In some specific embodiments, combined with Figure 2 and Figure 3 The air inlet 21 can be configured to be at least partially opposite to the air inlet 11, and the exhaust duct component 2 can be located at the position opposite to the air inlet 11 in the exhaust duct component 1, thus improving the duct performance. Of course, the present invention is not limited thereto.

[0058] According to some embodiments of the present invention, with reference to Figure 11 and Figure 12 The exhaust duct component 2 has a steam vent 24 located downstream of the steam inlet 22. In some embodiments, the exhaust duct component 2 may further include the steam vent 24, which may be located downstream of the steam inlet 22 and may communicate with the exhaust duct 20. Here, "downstream" refers to the position after the steam or airflow passes in the direction of steam or airflow flow.

[0059] Here, it can be understood that air can be supplied into the exhaust duct 20 through the air inlet 21, and steam can enter the exhaust duct 20 through the steam inlet 22. In this case, there is both air and steam in the exhaust duct 20, which raises the issue of the uniformity of air and steam.

[0060] To address the issue of uniformity between airflow and steam, the duct structure 100 according to an embodiment of the present invention, by providing a steam vent 24 and positioning the steam vent 24 downstream of the steam inlet 22, can effectively improve the uniformity of steam and airflow and facilitate better exhaust.

[0061] Furthermore, by placing the steam vent 24 downstream of the steam inlet 22, this application facilitates the backflow of a small amount of condensate, resulting in a more optimized and reasonable structure.

[0062] Furthermore, combined Figure 12 The steam vent 24 includes multiple vents (two or more), and the multiple steam vents 24 are configured to be larger in the middle and smaller on both sides. Here, taking one side wall of the exhaust duct 2 as an example, the middle refers to the middle position of the side wall, the two sides refer to the positions near the edge of the side wall, and the size refers to the area of ​​the shape enclosed by the outline of the steam vent 24.

[0063] In some embodiments, refer to Figure 12The plurality of steam vents 24 can be configured to decrease in number from the middle to both ends. In some embodiments, the plurality of steam vents 24 can be arranged symmetrically, but the invention is not limited thereto.

[0064] Since there are different wind speed distributions at different locations in the air duct, the air duct structure 100 according to the embodiment of the present invention optimizes the arrangement of the steam vents 24 by calculation in accordance with the wind speed. For example, if the wind speed is low on both sides, the steam vents 24 can be opened smaller, and if the wind speed is high in the middle, the steam vents 24 can be opened larger. This optimization of the design of the steam vents 24 is more conducive to improving the uniformity of steam and air.

[0065] Figure 11 and Figure 12 The present invention shows an embodiment in which the steam vent 24 is quadrilateral, but the present invention is not limited thereto. In some embodiments, the steam vent 24 may also be triangular, elliptical or circular, etc. The present invention does not limit the specific shape of the steam vent 24.

[0066] In some embodiments of the present invention, the exhaust duct component 2 may further include an inner plate (not shown), and a steam vent 24 may be provided on the inner plate. The exhaust duct component 2 may further include an inner plate, and the inner plate may be provided with a steam vent 24, which communicates with the exhaust duct 20.

[0067] In some embodiments, the inner plate may be triangular, quadrilateral, or irregular in shape, and the steam vents 24 may be evenly spaced on the inner plate. The steam vents 24 may be configured as through holes extending through the inner plate along the thickness direction. In some embodiments, the steam vents 24 may also be blind holes, etc., and the present invention does not specifically limit this. The arrangement of the steam vents 24 is preferably such that it can effectively achieve uniform mixing of steam and air.

[0068] In some embodiments of the present invention, combined with Figures 7 to 9 In the direction of airflow, the exhaust port 23 is located downstream of the steam inlet 24. In some embodiments, the steam entering the exhaust duct 20 through the steam inlet 22 can first be mixed with the air entering the exhaust duct 20 through the steam inlet 24, and then discharged through the exhaust port 23. This not only helps to cool the steam, but also helps to reduce the amount of steam discharged into the room.

[0069] Furthermore, combined Figure 2 as well as Figure 10 and Figure 11The exhaust port 23 and the steam inlet 24 are respectively located on two opposite side walls of the exhaust duct component 2. In some embodiments of the present invention, the exhaust duct component 2 may include two sets of side walls, each set of side walls including two opposite side walls. In either set of side walls, the steam inlet 24 may be located on one side wall, and the exhaust port 23 may be located on the other side wall. This can extend the movement path of steam and air in the exhaust duct 20, allowing for better mixing and thus better cooling and dehumidification of the steam.

[0070] In some embodiments of the present invention, reference is made to... Figure 9 The exhaust port 23 is configured to exhaust steam approximately tangentially along the exhaust duct 20. The exhaust port 23 is connected to the outside atmosphere. By configuring the exhaust port 23 to exhaust steam tangentially, this application makes the exhaust duct component 2 have excellent duct performance and facilitates air exhaust.

[0071] According to some embodiments of the present invention, in combination Figure 2 The exhaust duct component 2 includes a first sub-duct component 26 and a second sub-duct component 27. The first sub-duct component 26 and the second sub-duct component 27 are at a predetermined angle. The first sub-duct component 26 is connected to the exhaust duct component 1, and an air inlet 21 is formed on the first sub-duct component 26. An air inlet 22 and an exhaust outlet 23 are formed on the second sub-duct component 27.

[0072] In some embodiments of the present invention, reference is made to... Figure 3 The first sub-air duct component 26 and the second sub-air duct component 27 can be set approximately vertically. The first sub-air duct component 26 can extend horizontally, and the second sub-air duct component 27 can extend vertically. The exhaust duct component 2 can be L-shaped.

[0073] Of course, the present invention is not limited thereto. In some embodiments, the first sub-air duct component 26 and the second sub-air duct component 27 may also form an acute angle or an obtuse angle. Without considering the difference in air duct performance, the first sub-air duct component 26 and the second sub-air duct component 27 may also be set at a 180-degree angle, in which case the exhaust air duct component 2 is constructed as a straight air duct.

[0074] In some embodiments of the present invention, the exhaust duct component 2 can be a plastic part, and the exhaust duct component 2 can be integrally molded, which facilitates the processing and manufacturing of the exhaust duct component 2 and helps to reduce costs.

[0075] Furthermore, combined Figure 2 An arc-shaped transition section 28 may also be provided between the first sub-air duct component 26 and the second sub-air duct component 27. By providing the arc-shaped transition section 28, the exhaust duct component 2 can have a better air guiding effect.

[0076] In some embodiments of the present invention, the first sub-duct component 26, the second sub-duct component 27, and the arc-shaped transition portion 28 can be integrally formed. This not only improves the performance of the duct, but also simplifies the processing technology of the exhaust duct component 2, facilitates assembly, and reduces costs.

[0077] In some embodiments of the present invention, the exhaust duct component 2 and the air outlet duct component 1 can be an integral structural component (such as a plastic component). This facilitates the processing and manufacturing of the duct structure 100, improves assembly efficiency, and helps reduce costs.

[0078] In some embodiments of the present invention, reference is made to... Figure 2 The air outlet duct component 1 may include a lower housing 13 and an upper housing 14, which are detachably connected. The exhaust duct component 2 may be connected to the upper housing 14. In some embodiments, the exhaust duct component 2 and the upper housing 14 may be an integral structural component.

[0079] In some specific embodiments, the lower housing 13 and the upper housing 14 can be connected by snap-fit ​​connections and / or fasteners (screws, etc.).

[0080] In some embodiments of the present invention, combined with Figure 2 A latching portion 131 is formed on one of the lower housing 13 and the upper housing 14, and a latching portion 141 is formed on the other housing to engage with the latching portion 131. In some optional embodiments, the latching portion 131 may be formed on the lower housing 13 and the latching portion 141 may be formed on the upper housing 14, with the latching portion 141 engaging with the latching portion 131; in some optional embodiments, the latching portion 131 may be formed on the upper housing 14 and the latching portion 141 may be formed on the lower housing 13, with the latching portion 141 engaging with the latching portion 131.

[0081] Furthermore, referring to Figure 3 The lower housing 13 has a lower mating part, on which a lower mounting through hole may be formed. The upper housing 14 has an upper mating part, on which an upper mounting through hole may be formed. Fasteners are inserted into the lower mounting through hole and the upper mounting hole so that the lower housing 13 and the upper housing 14 can be detachably connected.

[0082] The following describes a specific embodiment of the air duct structure 100 according to the present invention with reference to the accompanying drawings.

[0083] Reference Figure 1 The air duct structure 100 includes an air outlet duct component 1 and an exhaust duct component 2. The air outlet duct component 1 has an air outlet duct 10, an air inlet 11 and an air outlet 12. Air can enter the air outlet duct 10 through the air inlet 11 and then be discharged through the air outlet 12.

[0084] The air inlet 11 and the air outlet 12 are arranged roughly vertically. This helps to reduce the length of the air duct structure 100, making the structure of the air duct structure 100 more compact and reducing the space occupied.

[0085] In some embodiments of the present invention, combined with Figure 5 The air outlet 12 can be configured to discharge air approximately tangentially along the air outlet duct 10. This tangential air discharge reduces duct resistance, thereby improving air utilization, optimizing duct performance, and enhancing airflow.

[0086] In some embodiments of the present invention, reference is made to... Figure 1 and Figure 3 The exhaust duct component 2 has an exhaust duct 20 (combined with...) Figure 12 ), air inlet 21 (combined with) Figure 7 ), steam inlet 22 and exhaust outlet 23 (combined) Figure 2 The air inlet 21 can be connected to the air outlet 12, which makes it easier for the air in the air outlet duct 10 to be diverted through the air inlet 21 and the air outlet 12 respectively.

[0087] In some specific embodiments, combined with Figure 2 and Figure 3 The air inlet 21 can be configured to be at least partially opposite to the air inlet 11, and the exhaust duct 2 can be located at the position opposite to the air inlet 11 in the exhaust duct 1, but the present invention is not limited thereto.

[0088] Specifically, when the air duct structure 100 is applied to the cooking equipment 1000, the cooking equipment 1000 may have an exhaust port 201. Furthermore, the exhaust port 201 may be connected to the air inlet 11. In this way, the air discharged from the exhaust port 201 may enter the exhaust duct 10 through the air inlet 11. Part of the air may be discharged from the exhaust port 12, and another part of the air may enter the steam exhaust duct 20 through the air inlet 21. This can cool and condense the steam entering the steam exhaust duct 20 from the steam inlet 22. Finally, the cooled steam is discharged from the exhaust port 23. In this way, on the one hand, the amount of steam discharged into the room can be reduced, and on the other hand, the steam can be cooled to prevent users from being scalded and improve safety. This can solve the technical problems of large steam discharge and high steam temperature that easily scald users in related technologies.

[0089] According to the air duct structure 100 of the present invention, air can enter the air outlet duct 10 through the air inlet 11, a portion of the air can be discharged through the air outlet 12, and another portion of the air can enter the exhaust duct 20 through the air inlet 21. This can cool and condense the steam entering the exhaust duct 20 through the steam inlet 22. Finally, the cooled steam is discharged through the exhaust outlet 23. In this way, on the one hand, the amount of steam discharged into the room can be reduced, and on the other hand, the steam can be cooled to prevent users from being scalded and improve safety. This can solve the technical problems of large steam discharge and high steam temperature that easily scald users in related technologies.

[0090] The duct structure 100 according to an embodiment of the present invention can cool high-temperature steam and reduce steam emissions, has good safety, and can also improve user experience.

[0091] In some embodiments, the exhaust duct 2 may further include a steam vent 24, which may be located downstream of the steam inlet 22 and may communicate with the exhaust duct 20. Here, "downstream" refers to the location after the steam or airflow passes in the direction of steam or airflow flow.

[0092] Here, it can be understood that air can be supplied into the exhaust duct 20 through the air inlet 21, and steam can enter the exhaust duct 20 through the steam inlet 22. In this case, there is both air and steam in the exhaust duct 20, which raises the issue of the uniformity of air and steam.

[0093] To address the issue of uniformity between airflow and steam, the duct structure 100 according to an embodiment of the present invention, by providing a steam vent 24 and positioning the steam vent 24 downstream of the steam inlet 22, can effectively improve the uniformity of steam and airflow and facilitate better exhaust.

[0094] Furthermore, by placing the steam vent 24 downstream of the steam inlet 22, this application facilitates the backflow of a small amount of condensate, resulting in a more optimized and reasonable structure.

[0095] Furthermore, combined Figure 12 The steam vent 24 includes multiple vents (two or more), and the multiple steam vents 24 are configured to be larger in the middle and smaller on both sides. Here, taking one side wall of the exhaust duct 2 as an example, the middle refers to the middle position of the side wall, the two sides refer to the positions near the edge of the side wall, and the size refers to the area of ​​the shape enclosed by the outline of the steam vent 24.

[0098] In some embodiments, the steam entering the exhaust duct 20 through the steam inlet 22 can first be mixed with the air entering the exhaust duct 20 through the steam vent 24, and then discharged through the exhaust port 23. This not only helps to cool the steam, but also helps to reduce the amount of steam discharged into the room.

[0099] The exhaust port 23 and the steam inlet 24 are respectively located on two opposite side walls of the exhaust duct component 2. This extends the movement path of steam and air within the exhaust duct 20, allowing for better mixing and thus better cooling and dehumidification of the steam.

[0100] Reference Figure 9 The exhaust port 23 is configured to exhaust steam approximately tangentially along the exhaust duct 20. The exhaust port 23 is connected to the outside atmosphere. By configuring the exhaust port 23 to exhaust steam tangentially, this application makes the exhaust duct component 2 have excellent duct performance and facilitates air exhaust.

[0101] Reference Figure 3 The first sub-air duct component 26 and the second sub-air duct component 27 can be arranged approximately vertically.

[0107] The duct structure 100 according to an embodiment of the present invention can cool high-temperature steam and reduce steam emissions, has good safety, and can also improve user experience.

[0108] Reference Figure 13 and Figure 14 According to a second aspect embodiment of the present invention, a cooking device 1000 includes a heat dissipation structure 200 and an air duct structure. Here, the cooking device 1000 can be a steam oven, oven, microwave oven, or a steam oven / grill combo, etc.

[0109] Specifically, refer to Figures 16 to 18 The heat dissipation structure 200 can be located at the bottom of the cooking cavity, and the heat dissipation structure 200 has an exhaust port 201; the air inlet 11 of the air duct structure is connected to the exhaust port 201, and the air duct structure is the air duct structure 100 described in the first aspect embodiment above.

[0110] The heat dissipation structure 200 may include a lower shell 202, an upper shell 203, and a heat dissipation fan 204 disposed between the lower shell 202 and the upper shell 203. The exhaust port 201 may be defined between the lower shell 202 and the upper shell 203. The heat dissipation fan 204 can supply air into the air duct structure 100 through the exhaust port 201 to further achieve the purposes of exhaust and heat dissipation.

[0111] In some specific embodiments of the present invention, combined with Figure 15 The cooking device 1000 also includes a rear cover 500, on which a plurality of vent holes 501 are formed. These vent holes 501 can extend through the rear cover 500 along its thickness direction and can be located at the edge of the rear cover 500. Furthermore, the vent holes 501 can communicate with the vent port 23 of the air duct structure 100, thus enabling the entire unit to vent steam to the rear. Of course, the invention is not limited to this; in some embodiments, steam can also be vented from the side, etc.

[0112] When the air duct structure 100 is applied to a cooking device 1000, and the cooking device 1000 is a microwave oven, the microwave oven may further include a magnetron 300 (in conjunction with...). Figure 18The magnetron 300 can be installed inside the air outlet duct 1, such as the air outlet duct 10, so that the magnetron 300 can be cooled by the air outlet 201.

[0113] And / or, when the air duct structure 100 is applied to the cooking device 1000, the cooking device 1000 may also include a transformer 400 (see reference). Figure 17 In some specific embodiments, a transformer 400 is provided at the air outlet 12, and the air outlet 12 can be used to dissipate heat from the transformer 400.

[0114] According to the second aspect of the present invention, the cooking device 1000, by setting the air duct structure 100 described in the first aspect of the present invention and connecting the air inlet 11 of the air duct structure with the air outlet 201, can dissipate the exhaust steam from the cooling fan 204 of the cooking device 1000 through the air outlet 12. The exhaust steam can be cooled and dehumidified by the whole machine exhausting steam to the rear. The structure is simple and the cost is low.

[0115] Specifically, when the air duct structure 100 is applied to the cooking equipment 1000, the cooking equipment 1000 will generate steam during the cooking process. The steam can be connected to the steam inlet 22 through a pipe, which facilitates the further discharge of the steam generated by the cooking equipment 1000 during the cooking process through the exhaust air duct 2.

[0116] The cooking equipment 1000 generates heat during operation. In order to ensure that the cooking equipment 1000 operates under good conditions, the technical problem of heat dissipation is involved. Therefore, the cooking equipment 1000 may also include a heat dissipation structure 200, which may include a fan or cooling fan, etc. The heat dissipation structure 200 has an exhaust port 201, so that the air generated by the heat dissipation structure 200 can be discharged through the exhaust port 201.

[0117] Furthermore, the exhaust vent 201 can be connected to the air inlet 11. In this way, the air discharged from the exhaust vent 201 can enter the air outlet duct 10 through the air inlet 11. Part of the air can be discharged through the air outlet 12, and the other part can enter the steam exhaust duct 20 through the air inlet 21. This can cool and condense the steam entering the steam exhaust duct 20 through the steam inlet 22. Finally, the cooled steam is discharged through the exhaust vent 23. In this way, on the one hand, the amount of steam discharged into the room can be reduced, and on the other hand, the steam can be cooled to prevent users from being scalded and improve safety. This can solve the technical problems of large steam discharge and high steam temperature that easily scald users in related technologies.
