[0038] As Figure 1-8 shown, an embodiment of the present application provides a steam exhaust structure, which is applied to a cooking appliance. The steam exhaust structure mainly includes an exhaust member 1, an exhaust cover 3, and a locking member 4. The exhaust member 1 includes an intake end and an outlet end that are relatively far apart, and a protruding clamping portion 11; the exhaust member 1 is passed through the housing 2 of the cooking appliance, and the clamping portion 11 is used to limit the relative position of the exhaust member 1 and the housing 2 of the cooking appliance; the exhaust cover 3 is provided with an exhaust hole 31, the exhaust cover 3 is detachably connected to the exhaust member 1 and covers the outlet end, and the exhaust hole 31 of the exhaust cover 3 is communicated with the outlet end; the locking member 4 is assembled to the exhaust member 1, and the locking member 4 is relatively close to the clamping portion 11 to form a clamping structure for clamping the housing 2 of the cooking appliance.

[0039] In this embodiment, the cooking appliance includes a housing 2, and the housing 2 includes at least one of a back plate, a side plate, and a top plate. The exhaust member 1 has a flow guiding structure for guiding the flow of steam. A through hole is provided in the thickness direction of the housing wall of the housing 2, and the exhaust member 1 is passed through the housing wall of the housing 2 through the through hole. The intake end and the outlet end of the exhaust member 1 are respectively located inside and outside the housing 2; wherein, the intake end is located inside the housing 2 and is communicated with the gas source, and the outlet end is provided outside the housing 2, and the steam is discharged from the cooking appliance after flowing through the exhaust member 1.

[0040] The locking member 4 and the clamping portion 11 are respectively arranged on the inner and outer sides of the housing 2. The housing wall of the housing 2 is clamped between the clamping portion 11 and the locking member 4 to fix the exhaust member 1 on the housing 2. Among them, the clamping portion 11 is located on the outer side of the housing 2, and the locking member 4 is located on the inner side of the housing 2; or, the clamping portion 11 is located on the inner side of the housing 2, and the locking member 4 is located on the outer side of the housing 2. The connection relationship between the clamping portion 11 and the locking member 4 changes according to the setting of the housing 2. If the exhaust member 1 is assembled on the horizontally arranged top plate, then one of the clamping portion 11 and the locking member 4 is supported and connected to the housing 2, and the other is in contact with the housing 2. If the exhaust member 1 is assembled on the vertically arranged side plate or back plate, both the clamping portion 11 and the locking member 4 are in contact with the housing 2.

[0041] The exhaust cover 3 is arranged on the outer side of the housing 2, and steam is discharged orderly through the exhaust holes 31 of the exhaust cover 3. The exhaust cover 3 is connected to at least one of the clamping portion 11, the main body of the exhaust member 1, the housing 2, and the locking member 4 to fix the relative position of the exhaust cover 3 and the air outlet end.

[0042] Through the steam exhaust structure provided by the embodiment of the present application, the exhaust member 1 penetrates through the housing 2 of the cooking appliance. The locking member 4 and the clamping portion 11 fix the exhaust member 1 on the housing 2 by clamping the housing 2. The intake end and the outlet end are relatively far away and are respectively located on the inner and outer sides of the housing 2 of the cooking appliance to guide the steam in the cooking appliance to flow through the exhaust member 1 and discharge from the cooking appliance. The steam exhaust structure in the embodiment of the present application is simpler and more compact, has a lower manufacturing cost, and occupies less space.

[0043] For the convenience of description, next, the embodiment of the present application will be specifically described with the steam exhaust structure arranged on the horizontal top plate, the clamping portion 11 located on the outer side of the housing 2, and the exhaust cover 3 connected to the clamping portion 11.

[0044] As shown in Figure 1 , FIGS. 4 and 5, as an alternative embodiment, the exhaust member 1 further includes a pipe body 12. The pipe body 12 has a hollow structure 13. One end of the pipe body 12 away from the exhaust cover 3 is the intake end, and one end close to the exhaust cover 3 is the outlet end. The two ends of the pipe body 12 are respectively used as the intake end and the outlet end. A cover recess 32 and a cover buckle 33 are arranged on one side of the exhaust cover 3. The clamping portion 11 is annular. The clamping portion 11 protrudes radially outward from the pipe body 12. The clamping portion 11 is provided with a clamping portion buckle 14 for cooperating with the cover buckle 33. The clamping portion 11 is accommodated in the cover recess 32, and the clamping portion buckle 14 and the cover buckle 33 cooperate to realize the clamping connection between the exhaust cover 3 and the exhaust member 1.

[0045] Based on the foregoing embodiments, in this embodiment, the main body of the pipe body 12 is cylindrical. The pipe body 12 is vertically penetrated through the plate body of the housing 2. The bottom end of the pipe body 12 is the air inlet end, and this air inlet end is communicated with the cavity for cooking ingredients (for example, the steam baking cavity) through a (silicone) hose; the top end of the pipe body 12 is the air outlet end. The clamping portion 11 is close to the air outlet end. The clamping portion 11 extends radially outward to form an annular structure with a certain thickness. The outer diameter of the clamping portion 11 is larger than the outer diameter of the pipe body 12.

[0046] A circular through hole is provided in the top plate of the housing 2 along the thickness direction. The top plate of the housing 2 is a glass plate, which can be processed together with other openings during the glass production process without changing the machine tool, improving production efficiency and cost.

[0047] The pipe body of the pipe body 12 has a circular through hole. The outer diameter of the clamping portion 11 is larger than the inner diameter of the circular through hole. The clamping portion 11 is stuck on the top of the top plate of the housing 2. The top plate of the housing 2 is supported and connected to the clamping portion 11 to limit the relative position between the pipe body 12 and the housing 2, ensuring that the air inlet end and the air outlet end of the pipe body 12 are respectively located on both sides of the housing 2. An appropriate amount of silicone glue is coated on the bottom of the clamping portion 11 and / or the top of the glass plate to achieve adhesion, which can improve the connection firmness between the two and also achieve waterproof penetration.

[0048] The exhaust cover 3 is in a disc shape. The exhaust cover 3 is horizontally arranged. The bottom of the exhaust cover 3 has a cover body recess 32 that is recessed upward. The cover body recess 32 is adapted to the clamping portion 11. The exhaust cover 3 covers the outside of the clamping portion 11. The clamping portion 11 extends into the cover body recess 32. The clamping portion buckle 14 and the cover body buckle 33 are adaptively clamped to fix the relative position between the exhaust cover 3 and the exhaust part 1. The exhaust hole 31 of the exhaust cover 3 is communicated with the air outlet end of the exhaust part 1, making the steam discharge more orderly.

[0049] In some embodiments, the top of the exhaust cover 3 is recessed downward, and the exhaust hole 31 is opened in the top recess of the exhaust cover 3, so that the water condensed on the top of the exhaust cover 3 flows to the cover body recess 32 and drops into the exhaust hole 31 without overflowing onto the housing 2.

[0050] The clamping portion buckle 14 and the cover body buckle 33 are clamped to each other through concave-convex cooperation to realize the connection between the exhaust cover 3 and the exhaust part 1. The following is a specific description.

[0051] As Figure 1, as shown in FIGS. 4 and 5, as an alternative embodiment, the clamping portion buckle 14 protrudes radially outward from the clamping portion 11. The clamping portion buckle 14 includes a first engaging protrusion 141 extending in a first direction and a first limiting protrusion 142 extending in a second direction. The first limiting protrusion 142 protrudes from the first engaging protrusion 141 in the second direction to form a first slot 143; the second direction is the direction in which the first engaging protrusion 141 is close to the intake end, and the first direction and the second direction intersect; the cover buckle 33 is disposed at the edge of the cover recess 32. The cover buckle 33 includes a second engaging protrusion 331. A second slot 332 is formed at an interval between the second engaging protrusion 331 and the bottom of the cover recess 32; the first engaging protrusion 141 is received in the second slot 332, and the second engaging protrusion 331 is received in the first slot 143.

[0052] Based on the foregoing embodiments, in this embodiment, the clamping portion buckle 14 is located on the side of the clamping portion 11 and protrudes radially outward from the clamping portion 11. The first engaging protrusion 141 is disposed near the top of the clamping portion 11. The first engaging protrusion 141 extends circumferentially (i.e., the first direction), that is, extends in the counterclockwise direction or the clockwise direction; the first limiting protrusion 142 extends vertically downward (i.e., the second direction, the first direction and the second direction in this embodiment are perpendicular to each other) and protrudes from the first limiting protrusion 142, and a first slot 143 is formed below the first limiting protrusion 142. The first slot 143 is a groove recessed from the first limiting protrusion 142 and the first engaging protrusion 141. The first slot 143 is close to the bottom of the clamping portion 11 and extends circumferentially along the clamping portion 11. Optionally, the first limiting protrusion 142 is disposed at an end of the first engaging protrusion 141. Optionally, a plurality of clamping portion buckles 14 are evenly distributed along the side of the clamping portion 11.

[0053] The opening of the cover recess 32 of the exhaust cover 3 is circular. The cover buckle 33 is disposed inside the inner edge of the opening of the cover recess 32. The second engaging protrusion 331 is disposed downward and extends radially inward. There is an interval between the second engaging protrusion 331 and the bottom of the cover recess 32. A second slot 332 is formed at an interval between the top of the second engaging protrusion 331 and the bottom of the cover recess 32. Optionally, a plurality of cover buckles 33 are evenly distributed along the opening edge of the cover recess 32.

[0054] During the assembly stage of the exhaust cover 3 and the exhaust component 1, the opening of the first engaging protrusion 141 corresponds to that of the second engaging groove 332, and the opening of the second engaging protrusion 331 corresponds to that of the first engaging groove 143; wherein, the opening of the second engaging groove 332 is located on the side of the first engaging protrusion 141 opposite to the first limiting protrusion 142. The exhaust cover 3 and the exhaust component 1 rotate relative to each other circumferentially until the second engaging protrusion 331 abuts against the first limiting protrusion 142. At this time, both the first engaging protrusion 141 and the second engaging protrusion 331 reach the engaging positions, realizing that the first engaging protrusion 141 is received in the second engaging groove 332, and the second engaging protrusion 331 is received in the first engaging groove 143; the top of the first engaging protrusion 141 abuts against the bottom of the cover recess 32, the bottom of the first engaging protrusion 141 abuts against the top of the second engaging protrusion 331, and the bottom of the second engaging protrusion 331 abuts against the top of the housing 2.

[0055] In some embodiments, at least one of the first engaging protrusion 141 and the second engaging protrusion 331 has a slight protrusion. Among them, the slight protrusion of the first engaging protrusion 141 faces the second engaging protrusion 331; the slight protrusion of the second engaging protrusion 331 faces the first engaging protrusion 141. The slight protrusion creates a certain obstruction to the installation and disassembly of the exhaust cover 3, making it not easy for the exhaust cover 3 to fall off or shift.

[0056] As Figure 1 shown in FIGS. 4 and 5, as an alternative embodiment, the exhaust component 1 further includes a pipe body buckle 15, which protrudes outward from the pipe body 12 and is away from the clamping position 11; the locking member 4 is annular, and a locking member buckle 41 is provided on the inner side of the locking member 4. The locking member 4 is sleeved on the outside of the pipe body buckle 15, and the pipe body buckle 15 and the locking member buckle 41 cooperate to realize the clamping connection between the locking member 4 and the exhaust component 1.

[0057] Based on the foregoing embodiments, in this embodiment, the pipe body buckle 15 is located below the clamping position 11 and relatively far from the clamping position 11. The locking member 4 is sleeved on the outside of the pipe body buckle 15, and the locking member buckle 41 provided on the inner side of the locking member 4 is clamped to form a locking relationship, fixing the relative position between the locking member 4 and the pipe body 12, so that a gap is formed between the locking member 4 and the clamping position 11, and this gap serves as the space for clamping the housing 2. The top of the locking member 4 abuts against the bottom of the housing 2 and presses the housing 2 upward, and the clamping position 11 forms a downward pressure on the housing 2 to ensure the stability of clamping the housing 2.

[0058] An inward depression is provided on the outer edge of the locking member 4 to form a gear-shaped edge, which is convenient for rotating and installing the locking member 4. The material of the locking member 4 includes plastic. The thickness of the locking member 4 is slightly less than the top plate of the housing 2, and the locking member 4 realizes locking by the slight deformation of the plastic material.

[0059] The tube body buckle 15 and the cover body buckle 33 are in concave-convex fit to realize the clamping connection between the exhaust cover 3 and the exhaust part 1. The following is a specific description.

[0060] As Figure 1 , as shown in FIGS. 4 and 5, as an alternative embodiment, the tube body buckle 15 includes a third engaging protrusion 151 extending in the third direction and a second limiting protrusion 152 extending in the fourth direction. The second limiting protrusion 152 protrudes from the third engaging protrusion 151 in the fourth direction to form a third slot 153; the fourth direction is the direction in which the third engaging protrusion 151 is close to the air outlet end, and the third direction and the fourth direction intersect; the locking member buckle 41 includes a fourth engaging protrusion 411 extending in the fifth direction and a third limiting protrusion 412 extending in the sixth direction.

[0061] Based on the foregoing embodiment, in this embodiment, the tube body buckle 15 protrudes radially outward from the tube body 12 of the tube body 12. Along the axial direction of the tube body 12, the tube body buckle 15 is disposed between the air inlet end and the air outlet end. The third engaging protrusion 151 extends circumferentially (i.e., the third direction), that is, extends in the counterclockwise direction or the clockwise direction; the second limiting protrusion 152 extends vertically upward (i.e., the fourth direction, the third direction and the fourth direction in this embodiment are perpendicular to each other) and protrudes from the third engaging protrusion 151 to form a third slot 153 above the third limiting protrusion 412. The third slot 153 is a groove recessed from the second limiting protrusion 152 and the third engaging protrusion 151, and the third slot 153 extends circumferentially along the tube body 12. Optionally, the second limiting protrusion 152 is disposed at the end of the third engaging protrusion 151. Optionally, a plurality of tube body buckles 15 are evenly distributed circumferentially.

[0062] The fourth engaging protrusion 411 extends circumferentially (i.e., the fifth direction) along the locking member 4, that is, extends in the counterclockwise direction or the clockwise direction; the third limiting protrusion 412 extends vertically downward (i.e., the sixth direction, the fifth direction and the sixth direction in this embodiment are perpendicular to each other) and protrudes from the fourth engaging protrusion 411 to form a fourth slot 413 below the fourth engaging protrusion 411. The fourth slot 413 is a groove recessed from the fourth engaging protrusion 411 and the third limiting protrusion 412. The fourth slot 413 extends circumferentially along the locking member 4. Optionally, the third limiting protrusion 412 is disposed at the end of the fourth engaging protrusion 411. Optionally, a plurality of locking member buckles 41 are evenly distributed circumferentially.

[0063] During the assembly stage of the locking member 4 and the tube body 12, the third engaging protrusion 151 corresponds to the opening of the fourth engaging groove 413, and the fourth engaging protrusion 411 corresponds to the opening of the third engaging groove 153; wherein, the opening of the fourth engaging groove 413 is located on the side of the third engaging protrusion 151 opposite to the second limiting convex portion 152. The opening of the third engaging groove 153 is located on the side of the fourth engaging protrusion 411 opposite to the third limiting convex portion 412. The locking member 4 and the tube body 12 rotate relative to each other circumferentially until the third engaging protrusion 151 abuts against the third limiting convex portion 412 and the fourth engaging protrusion 411 abuts against the second limiting convex portion 152. At this time, both the third engaging protrusion 151 and the fourth engaging protrusion 411 reach the engaging position, realizing that the third engaging protrusion 151 is received in the fourth engaging groove 413 and the fourth engaging protrusion 411 is received in the third engaging groove 153; the top of the third engaging protrusion 151 abuts against the bottom of the fourth engaging protrusion 411, and the top of the fourth engaging protrusion 411 abuts against the bottom of the housing 2.

[0064] As Figure 1 shown in FIGS. 4 and 5, as an alternative embodiment, the third engaging protrusion 151 is provided with adjacent first teeth 154 and a first groove 155 on the side facing the third engaging groove 153.

The second teeth 414 protrude downward, and the second groove 415 is recessed upward. The first teeth 154 are received in the second groove 415, and the second teeth 414 are received in the first groove 155. The first teeth 154 and the second teeth 414 play a hindering role to prevent the third engaging protrusion 151 from sliding out of the fourth engaging groove 413 and the fourth engaging protrusion 411 from sliding out of the third engaging groove 153, thereby ensuring the stability of the engagement between the tube body buckle 15 and the locking member buckle 41 and preventing the locking member 4 from falling off.

[0066] As Figure 8 shown, as an alternative embodiment, the locking member 4 further includes a support convex portion 42. The support convex portion 42 protrudes radially inward of the locking member 4, and the support convex portion 42 supports the tube body buckle 15.

[0067] Based on the foregoing embodiments, in this embodiment, the supporting convex portion 42 is annular, and the supporting convex portion 42 is disposed below the locking member buckle 41. More specifically, the top of the supporting convex portion 42 is connected to the bottom of the third limiting convex portion 412, and the fourth card slot 413 is recessed in the radial direction of the locking member 4 relative to the supporting convex portion 42. The bottom of the third engaging protrusion 151 abuts against the top of the supporting convex portion 42 to ensure the stability of the engagement between the tube body buckle 15 and the locking member buckle 41 and prevent the locking member 4 from falling off.

[0068] As Figures 9-11 shown, as an alternative embodiment, the steam exhaust structure further includes a sealing ring 5. The sealing ring 5 is disposed along the inner side of the air outlet end, and the exhaust cover 3 presses on the sealing ring 5. In the axial direction of the tube body 12, the projection of the exhaust hole 31 does not coincide with the projection of the sealing ring 5.

[0069] Based on the foregoing embodiments, in this embodiment, the sealing ring 5 is horizontally disposed, the exhaust cover 3 presses on the sealing ring 5, and the sealing ring 5 deforms to achieve the sealing between the exhaust cover 3 and the exhaust member 1. An exhaust hole 31 is formed in the central region of the exhaust cover 3. The exhaust hole 31 includes a plurality of sub-exhaust holes 31. One sub-exhaust hole 31 is located at the center of the exhaust cover 3, and the remaining sub-exhaust holes 31 surround the sub-exhaust hole 31 located at the center of the exhaust cover 3 for the orderly discharge of steam. The projection of the exhaust hole 31 does not coincide with the projection of the sealing ring 5 to ensure the steam flow area. In addition, the flow area of the exhaust hole 31 is larger than the steam flow area of the foregoing hollow structure 13 to ensure the steam discharge efficiency.

[0070] As Figure 1 and 4 shown, as an alternative embodiment, an installation groove 16 for assembling the sealing ring 5 is provided on the inner side of the air outlet end; a protruding positioning convex portion 51 is provided on one side of the sealing ring 5, and the positioning convex portion 51 is embedded in the installation groove 16 to achieve the sealed connection between the sealing ring 5 and the exhaust member 1; a deformation convex portion 52 is provided on the side of the sealing ring 5 relative to the positioning convex portion 51, and the exhaust cover 3 presses on the deformation convex portion 52 to cause deformation to achieve the sealed connection between the sealing ring 5 and the exhaust cover 3.

[0071] Based on the foregoing embodiments, in this embodiment, the installation groove 16 is disposed along the inner side of the air outlet end to form an annular structure. The installation groove 16 is recessed downward and has an upward opening.

[0072] The bottom side of the sealing ring 5 protrudes from the downwardly extending positioning convex portion 51. The positioning convex portion 51 is adapted to the installation groove 16 and also has an annular structure. The assembly of the sealing ring 5 and the exhaust member 1 is achieved through the concave-convex fit between the positioning convex portion 51 and the installation groove 16.

[0073] On the top side of the sealing ring 5, there are multiple deformation protrusions 52. The deformation protrusions 52 are circular. The multiple deformation protrusions 52 are concentrically arranged and one is sleeved on another. The longitudinal section of the deformation protrusion 52 is semi-circular, rectangular or triangular. When the deformation protrusion 52 is squeezed by the exhaust cover 3, it deforms, and the exhaust cover 3 is tightly connected to the sealing ring 5, so as to enhance the friction force with the exhaust cover 3 to prevent the two from rotating. It can also form multiple layers of tight combination, thereby eliminating gaps, having a better sealing effect, and preventing condensed water or steam from diffusing from the exhaust cover 3 to the glass plate of the stove.

[0074] Optionally, the clamping part 11, the pipe body 12, the hollow structure 13, the clamping part buckle 14, and the pipe body buckle 15 are integrally formed.

[0075] Optionally, the exhaust hole 31, the cover body recess 32, and the cover body buckle 33 of the exhaust cover 3 are integrally formed.

[0076] Optionally, the locking part buckle 41 and the supporting convex part 42 are integrally formed.

[0077] Based on the same inventive concept, an embodiment of the present application provides a stove, which includes a housing 2 and the steam exhaust structure in any one of the foregoing embodiments. The steam exhaust structure penetrates through the housing 2, and the intake end and the outlet end of the exhaust part are respectively arranged on the inner and outer sides of the housing 2.
