Description

Technical Field

[0001] The utility model relates to the technical field of steam ovens, in particular to a wind shielding mechanism and a steam oven. Background Art

[0002] To improve the appearance of the steam oven and meet the increasingly strict usage experience of customers, it has become inevitable to replace the traditional hot air blower baffle with a corona hot air blower baffle. Compared with the relatively exposed air inlet design of the traditional hot air blower baffle, the corona hot air blower baffle well preserves the visual integrity. Looking from the front, it appears as a whole, covering components such as fan blades that affect the appearance, greatly enhancing the appearance.

[0003] The existing implementation scheme of the corona hot air blower is to extend a platform inward at the air inlet of the hot air blower baffle, set mounting posts on the platform, and open mounting holes on the air inlet baffle, or set threads on the mounting posts and press the air inlet baffle to the mounting posts through screws, or expose the mounting posts from the air inlet baffle and weld the air inlet baffle to the mounting posts. In the existing technical solutions, holes need to be opened on the air inlet baffle, resulting in an incomplete and uneven surface of the air inlet baffle, which does not meet the existing market requirements; in addition, the existing air inlet baffle is difficult to disassemble or even cannot be disassembled. Generally, when cleaning, users need to insert their fingers into the gap to remove the dirt on the back of the air inlet baffle, which is likely to cause injury to users and pose a safety hazard. Since the back of the air inlet baffle is not visible, it is easy to generate cleaning dead corners, greatly damaging the cleaning experience of users. Summary of the Utility Model

[0004] Based on the deficiencies of the existing air inlet baffle of the corona hot air blower, which has an uneven surface and is difficult to clean, it is necessary to provide a wind shielding mechanism and a steam oven.

[0005] A wind shielding mechanism, comprising:

[0006] A hot air blower baffle, including a first plate body having an air inlet hole and a mounting seat fixed to the first plate body; and

[0007] An air inlet baffle, including a second plate body spaced on one side of the first plate body and a connecting member fixed to the side of the second plate body facing the first plate body. The projection of the second plate body on the first plate body covers the air inlet hole, and the connecting member is detachably mounted on the mounting seat.

[0008] With such a setting, by providing a connecting member on one side of the air inlet baffle, it is ensured that the flatness of the other side of the air inlet baffle is not affected when the connecting member is connected to the mounting seat. And the connecting member being detachably mounted on the mounting seat facilitates the user to remove the air inlet baffle and perform cleaning operations, preventing the appearance of cleaning dead corners, thereby avoiding the accumulation of dirt on the back of the air inlet baffle.

[0009] In one embodiment, the first plate body has a mounting platform extending inwards from the edge of the air inlet hole. The mounting seat includes a rivet riveted to the mounting platform and a sleeve extending from the rivet towards the second plate body, and the connecting member is detachably mounted on the sleeve.

[0010] With such a setting, making holes on the mounting platform by using rivets is beneficial to improving the assembly efficiency. The rivet and the sleeve are combined into a mounting seat, and the use of a mold is eliminated through a split assembly method, which is convenient for purchasing standard parts for assembly production and is beneficial to reducing production costs.

[0011] In one embodiment, the rivet has a jack, and the sleeve is press-fitted into the jack.

[0012] With such a setting, the jack can tightly hold the sleeve in the radial direction. On the one hand, it is beneficial to increasing the structural strength of the sleeve, and on the other hand, it can also prevent the sleeve from expanding and deforming, avoiding the inability to assemble between the connecting member and the sleeve.

[0013] In one embodiment, the sleeve is welded to the rivet.

[0014] With such a setting, the assembly between the sleeve and the rivet is firm, which is beneficial to enhancing the structural strength of the mounting seat.

[0015] In one embodiment, the connecting member is tubular, and the connecting member is sleeved on the sleeve.

[0016] With such a setting, the sleeving method facilitates the disassembly and assembly of the air inlet baffle, the operation is simple, and it is beneficial to improving the user experience.

[0017] In one embodiment, the rivet is sealed at one end of the connecting member away from the second plate body for wrapping the sleeve with the connecting member.

[0018] With such a setting, since the sleeve is wrapped by the rivet and the connecting member, dirt during use is not easily introduced into the sleeve. Considering that the sleeve is fixed to the rivet at the factory, this avoids increasing the cleaning difficulty for users. In addition, since the rivet is generally a standard part, the length error of the rivets at different positions is relatively small, and the connecting member abutting against the rivet can also ensure that the second plate body of the air inlet baffle will not tilt during assembly.

[0019] In one embodiment, the sleeve includes a tube body and an elastic body extending from the outer peripheral wall of the tube body, and the elastic body abuts against the inner peripheral wall of the connecting member.

[0020] In this way, the setting of the extended elastomer means that there is a visible gap between the inner walls of the tube body and the connecting piece, which makes it convenient to put the connecting piece on the tube body, reduces the difficulty of assembling the connecting piece and the mounting seat, and facilitates the installation of the air inlet baffle back to the hot air blower baffle after cleaning; the elastomer can limit the relative shaking between the tube body and the connecting piece, thereby avoiding the noise caused by the vibration of the fan and the airflow causing the collision between the tube body and the connecting piece, which is beneficial to improving the user experience.

[0021] In one of the embodiments, a side of the elastic body facing away from the tube body is a curved surface that matches the shape of the inner wall of the sleeve.

[0022] Such an arrangement increases the tightness of the fit between the tube body and the inner wall of the connecting piece, which helps to further reduce the shaking between the tube body and the connecting piece.

[0023] In one embodiment, the elastic body includes a connecting portion extending from the tube body, an abutting portion extending axially from the connecting portion, and a bending portion gradually approaching the tube body in a direction axially away from the connecting portion, and the abutting portion abuts against the inner wall of the sleeve.

[0024] In this way, the setting of the bending portion not only increases the smoothness of assembly between the sleeve and the connector, but also can guide the elastic body to deform itself, thereby avoiding accidental breakage of the elastic body during the assembly process.

[0025] In one embodiment, the elastic body is a stamped part and is integrally connected to the tube body.

[0026] Such an arrangement increases the connection strength between the elastomer and the tube body and improves production efficiency. The elastomer produced by stamping also has high precision, which is beneficial to improving the yield rate of the sleeve.

[0027] The present application also relates to a steam oven, comprising a box body, a hot air blower main body and the wind shielding mechanism as described above, wherein the hot air blower main body is installed in the box body, the wind shielding mechanism is arranged in the box body and the cover is arranged on the hot air blower main body.

[0028] With such a configuration and the wind shield mechanism provided in the present application, when the user opens the steam oven, what comes into view is a flat air inlet baffle. The flat air inlet baffle will not affect the circulation of internal airflow. The easy-to-remove feature of the air inlet baffle also makes it convenient for users to clean it, thereby improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0037] In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0038] In addition, the terms "first" and "second" are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0039] In the present utility model, unless otherwise clearly stipulated and defined, terms such as "installed", "connected", "joined", "fixed", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0040] In the present utility model, unless otherwise clearly stipulated and defined, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature is at a higher horizontal level than the second feature.

[0041] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation.

[0042] To enhance the appearance of the steam oven and meet the increasingly strict usage experience requirements of customers, it has become inevitable to replace the traditional hot air blower baffle with a corona hot air blower baffle. Compared with the relatively exposed air inlet design of the traditional hot air blower baffle, the corona hot air blower baffle well preserves the visual integrity. Looking from the front, it appears as a seamless whole, covering components such as the fan blades that affect the appearance, thus greatly enhancing the appearance.

[0043] The existing implementation scheme of the corona type hot air blower is to extend a platform inward at the air inlet on the hot air blower baffle and set a mounting column on the platform and open a mounting hole on the air inlet baffle, or set a thread on the mounting column and press the air inlet baffle to the mounting column by screws, or expose the mounting column from the air inlet baffle and weld the air inlet baffle to the mounting column. In the existing technical solutions, holes need to be opened on the air inlet baffle, resulting in an incomplete air inlet baffle and an uneven surface, which does not meet the existing market demand. In addition, the existing air inlet baffle is difficult or even impossible to disassemble. For example, in the existing screw fastening method, since the wind shield mechanism is located in the inner tank of the steam oven, it is restricted by the entrance of the inner tank. When the user only removes the air inlet baffle, the viewing angle is limited, and the operation is also limited. When reinstalling, the flatness of the air inlet baffle is not easy to adjust. Therefore, under normal circumstances, the user needs to put his fingers into the gap to remove the dirt on the back of the air inlet baffle when cleaning, which can easily cause injury to the user and bring safety hazards. Since the back of the air inlet baffle is not visible, it is easy to create cleaning dead corners, which greatly damages the user's cleaning experience.

[0044] Based on this, it is necessary to provide a windshield mechanism and a steam oven that are visually complete and convenient for users to clean by themselves.

[0045] See also Figures 1 to 3 , Figure 1 Schematic diagram of the structure of the wind shielding mechanism in one embodiment of the utility model. Figure 2 for Figure 1 The exploded structural diagram of the wind shielding mechanism shown in FIG. Figure 3 for Figure 2 A schematic diagram of the structure of the air inlet baffle 20 in another perspective. The wind shielding mechanism provided in the present application includes a hot air blower baffle 10 and an air inlet baffle 20, the hot air blower baffle 10 includes a first plate body 11 with an air inlet and a mounting seat 12 fixed to the first plate body 11, the air inlet baffle 20 includes a second plate body 21 and a connecting member 22 fixed to one side of the second plate body 21, the second plate body 21 is arranged at an interval from the first plate body 11, the connecting member 22 is located on the side of the second plate body 21 facing the first plate body 11, and the connecting member 22 is detachably mounted on the mounting seat 12. Since the connecting member 22 is fixedly arranged on the side of the second plate body 21 facing the first plate body 11, the flatness of the side of the air inlet baffle 20 facing away from the hot air blower baffle 10 will not be affected, and the connecting member 22 is detachably installed on the mounting seat 12, which makes it convenient for the user to remove the air inlet baffle 20 and perform cleaning operations, preventing sanitary dead corners during cleaning, thereby avoiding the accumulation of dirt on the back of the air inlet baffle 20.

[0046] Optionally, in an embodiment provided by the present application, the connecting member 22 is welded to the side of the second plate body 21 facing the first plate body 11. It should be noted that the connecting member 22 and the second plate body 21 are pre-fixed. Therefore, when the connecting member 22 and the second plate body 21 form an integral structure, it is not restricted by the operation surface. For example, when welding the connecting member 22 to the second plate body 21, the welding operation can be directly performed on one side of the second plate body 21 without opening an auxiliary hole on the second plate body 21 to expose the connecting member 22, thereby ensuring the flatness of the side of the air inlet baffle 20 facing away from the first plate body 11. It can be understood that the air inlet baffle 20 can also be an integrally cast part, and the connecting member 22 and the second plate body 21 are integrally formed by die casting, which is also beneficial to improving the structural strength of the air inlet baffle 20.

[0047] Please refer to Figure 2 , in an embodiment provided by the present application, the first plate body 11 has a mounting platform 112 extending inwards from the edge of the air inlet hole 111. The mounting seat 12 includes a rivet 121 and a sleeve 122. The rivet 121 is riveted to the mounting platform 112, and the sleeve 122 extends from the rivet 121 towards the second plate body 21. The connecting member 22 is detachably mounted on the sleeve 122. Using the rivet 121 to open a hole on the mounting platform 112 is beneficial to improving the assembly efficiency. The rivet 121 and the sleeve 122 are combined into the mounting seat 12. By the way of split assembly, the use of a mold is eliminated, which is convenient for purchasing standard parts for assembly production and is beneficial to reducing production costs.

[0048] Optionally, in an embodiment provided by the present application, the rivet 121 has a jack, and the sleeve 122 is press-fitted into the jack. The sleeve 122 in the jack can be radially tightened by the sleeve 122. On the one hand, it is beneficial to increase the structural strength of the sleeve 122. On the other hand, it can also prevent the sleeve 122 from expanding and deforming, avoiding the inability to assemble between the connecting member 22 and the sleeve 122. It can be understood that in other embodiments, if only considering the connection between the rivet 121 and the sleeve 122, the rivet 121 can also be provided with a boss facing the second plate body 21, and the boss is press-fitted into the sleeve 122 to fix the sleeve 122 to the rivet 121.

[0049] Optionally, in an embodiment provided by the present application, the sleeve 122 is welded to the rivet 121, so that the assembly between the sleeve 122 and the rivet 121 is firm, which is beneficial to enhancing the structural strength of the mounting seat 12.

[0050] Optionally, in an embodiment provided by the present application, the connecting member 22 is tubular, and the connecting member 22 is sleeved on the sleeve 122. The sleeving method facilitates the disassembly and assembly of the air inlet baffle 20, with simple operation, which is beneficial to improving the user experience. Further, in one embodiment, the connecting member 22 extends from the second plate body 21 in a direction perpendicular to the plate surface of the second plate body 21, so that the disassembly path of the air inlet baffle 20 is simple and direct, facilitating the user to quickly disassemble, which is beneficial to improving the user experience.

[0051] Please refer to Figures 1 to 3 , optionally, in an embodiment provided by the present application, the rivet 121 is sealed at one end of the connecting member 22 away from the second plate body 21 for wrapping the sleeve 122 with the connecting member 22. Since the sleeve 122 is wrapped by the rivet 121 and the connecting member 22, dirt during use is not easily introduced into the sleeve 122. Considering that the sleeve 122 is already fixed to the rivet 121 at the factory, this avoids increasing the cleaning difficulty for the user. In addition, since the rivet 121 is generally a standard part, the length error of the rivets 121 at different positions is small, and the connecting member 22 abuting against the rivet 121 can also ensure that the second plate body 21 of the air inlet baffle 20 will not tilt during assembly.

[0052] Please refer to Figure 4 , Figure 4 is Figure 2 a schematic structural view of the sleeve 122 in

[0053] Further, in order to increase the tightness of the fit between the inner wall of the pipe body 1221 and the connecting piece 22, in an embodiment provided in the present application, the side of the elastomer 1222 facing away from the pipe body 1221 is an arc surface adapted to the inner wall shape of the sleeve 122. In this way, the shaking between the pipe body 1221 and the connecting piece 22 is further reduced.

[0054] Optionally, in an embodiment provided in the present application, the elastomer 1222 includes a connecting portion 12221, an abutting portion 12222, and a bending portion 12223. The connecting portion 12221 extends from the outer extension of the pipe body 1221. The abutting portion 12222 extends axially from the connecting portion 12221. The bending portion 12223 gradually approaches the pipe body 1221 along the axial direction away from the connecting portion 12221 from the abutting portion 12222. The abutting portion 12222 abuts against the inner wall of the sleeve 122. The setting of the bending portion 12223 not only increases the smoothness of the assembly between the sleeve 122 and the connecting piece 22, but also can guide the deformation of the elastomer 1222 itself, avoiding accidental breakage of the elastomer 1222 during the assembly process. Specifically, the elastomer 1222 is a stamping part and is integrally connected to the pipe body 1221. During actual production, the sleeve 122 is formed by rolling a metal sheet. The elastomer 1222 is pre-stamped at a preset position on the metal sheet by stamping, which reduces the production cost and can also ensure the opening accuracy of the position of the elastomer 1222, which is beneficial to improving the yield of the sleeve 122.

[0055] Please refer to Figure 5 , Figure 5 FIG. 10 is a schematic structural diagram of a hot air blower main body 30 and a wind shielding mechanism in a steam oven according to an embodiment provided in the present application. The steam oven includes a box body, a hot air blower main body 30, and the wind shielding mechanism as described above. The box body includes an outer shell and an inner liner provided in the outer shell. There is a gap between the wind shielding mechanism and the rear wall of the inner liner to form an installation space in the inner liner. The hot air blower main body 30 is accommodated in the installation space and installed on the rear wall of the inner liner. Specifically, the middle part of the first plate body 11 of the hot air blower baffle 10 is recessed toward one side to form an installation groove for accommodating the hot air blower main body 30. The edge of the first plate body 11 is fixedly connected to the outer shell of the box body. By adopting the wind shielding mechanism provided in the present application, when the user opens the steam oven, what comes into view is a flat air inlet baffle 20. The flat air inlet baffle 20 does not affect the flow of internal air. The easy-to-detach feature of the air inlet baffle 20 also facilitates the user to clean and improves the user experience.

[0056] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0057] The above-described embodiments merely represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
