Abstract
Description
Technical Field
[0001] This application relates to the field of cooking utensil technology, and more particularly to a cooking utensil. Background Technology
[0002] Steam ovens and other cooking appliances generate a large amount of water vapor and steam during the cooking process. Therefore, they are usually equipped with an exhaust pipe to expel the steam or water vapor from the cooking cavity. This exhaust pipe is typically located between the outer wall of the cooking cavity shell and the inner wall of the outer shell. One end of the exhaust pipe is connected to and communicates with the cooking cavity shell, while the other end extends outward between the outer wall of the cooking cavity shell and the inner wall of the outer shell to connect to an external exhaust system.
[0003] With the design maximizing the space of the cooking cavity, the space between the outer wall of the cooking cavity shell and the inner wall of the outer shell becomes smaller and smaller. As a result, when the exhaust pipe is bent, the narrow space makes it easy for the exhaust pipe to be squeezed, which will affect the internal connectivity of the exhaust pipe and reduce the steam discharge effect. Utility Model Content
[0004] This application provides a cooking appliance that can effectively improve the internal connectivity of the exhaust pipe assembly and enhance the exhaust performance of the exhaust assembly.
[0005] One aspect of this application provides a cooking utensil, comprising:

[0007] An inner shell, located within the outer shell, having a cooking cavity;
[0008] An exhaust pipe assembly, the exhaust pipe assembly being located between the inner housing and the outer housing;
[0009] The exhaust pipe assembly includes:
[0010] Straight pipe fittings;
[0011] The bend pipe fitting is a separate component from the straight pipe fitting. The bend pipe fitting includes a first connector and a second connector. The opening directions of the first connector and the second connector are set at an angle. The first connector is connected to the inner shell and communicates with the cooking cavity. The second connector is connected to and communicates with one end of the straight pipe fitting. The other end of the straight pipe fitting is communicated with the outside.
[0012] By including interlocking bends and straight pipes in the exhaust assembly, the bends can change the orientation of the interfaces on the inner shell, reducing the angle between the opening direction of the second connector and the surface of the inner shell. This allows the straight pipes to effectively reduce or avoid bending when connected to the second connector, thus preventing compression caused by bending and avoiding internal blockage due to compression and bending. This effectively improves the internal connectivity of the exhaust pipe assembly and enhances its exhaust performance.
[0013] One possible implementation also includes:
[0014] A connector, a portion of which is located inside the inner shell and another portion of which is located outside the inner shell, and the portion of the connector located outside the inner shell is connected to the bend. The connector and the bend clamp the inner shell to achieve the connection between the bend and the inner shell.
[0015] In one possible implementation, a seal is also included; the seal is located between the first joint and the connector, and the seal is used to provide a seal between the first joint and the connector.
[0016] In one possible implementation, one of the first connector and the other part of the connector includes a first limiting platform and a first connecting portion connected together;
[0017] The other one includes a second connecting portion, wherein the first limiting platform extends from the portion connected to the first connecting portion into the interior of the first connecting portion;
[0018] The second connecting part is fixedly connected to the inner side of the first connecting part, and the second connecting part and the first limiting platform respectively abut against the two ends of the sealing member.
[0019] In one possible implementation, the bend further includes a straight pipe section, one end of which is connected to the first connector and the other end of which is connected to the second connector, and the extension direction of the straight pipe section is consistent with the opening direction of the second connector.
[0020] In one possible implementation, one of the outer periphery of the second connector and the inner wall of the straight pipe has a snap-fit portion, and the other has a snap-fit groove that mates with the snap-fit portion.
[0021] The straight pipe fitting is sleeved on the second connector, and the snap-fit part is snapped into the snap-fit groove.
[0022] In one possible implementation, the opening directions of the first connector and the second connector are perpendicular.
[0023] In one possible implementation, the second connecting part is connected to the first connecting part by a threaded connection.
[0024] In one possible implementation, the bent pipe is made of plastic and the straight pipe is made of rubber.
[0025] In one possible implementation, the outer diameter of the straight pipe section is greater than the outer diameter of the second connector, and the portion of the straight pipe section that is greater than the second connector forms a second limiting platform, with the end of the straight pipe fitting abutting against the second limiting platform.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0044] This application provides a cooking appliance, which may be an oven, a steam oven, a steam-grill combination appliance, a grill-microwave combination appliance, or a steam-grill-microwave combination appliance. In this application embodiment, a steam-grill-microwave combination appliance is used as an example for explanation.
[0045] Figure 1 This is an exploded view of a cooking utensil provided in an embodiment of this application. Figure 2 This is a schematic diagram of the structure of a cooking utensil provided in an embodiment of this application.
[0046] See Figure 1 As shown, the cooking appliance 100 may include an outer shell 110 and an inner shell 120, wherein the inner shell 120 may be located inside the outer shell 110 and the inner shell 120 may form a cooking cavity, which may be used to hold food for heating.
[0047] Cooking appliances may also include an exhaust pipe, which may be located between the inner shell and the outer shell. One end of the exhaust pipe may be connected to the inner shell, and the other end may extend outward in the space between the inner shell and the outer shell to connect to an external exhaust device.
[0048] With the design maximizing the space of the cooking cavity, the space between the inner shell and the outer shell becomes smaller and smaller. As a result, when the exhaust pipe is bent, the narrow space makes it easy for the exhaust pipe to be squeezed, which will affect the internal connectivity of the exhaust pipe and reduce the steam discharge effect.
[0049] In related technologies, the exhaust pipe is designed with an elbow at the end to allow the exhaust pipe to bend. However, exhaust pipes are usually made of rubber, and rubber pipes with elbows are complex to process and have high production costs, which increases the overall cost of cooking appliances.
[0050] To address the aforementioned issues, this application provides a cooking appliance that includes a venting assembly comprising a bent pipe and a straight pipe that cooperate with each other. The bent pipe can change the orientation of the interface on the inner shell, reducing the angle between the opening direction of the second connector and the surface of the inner shell. This allows the straight pipe to effectively reduce or avoid bending when connected to the second connector, thereby effectively preventing compression caused by bending and avoiding internal blockage due to compression and bending. This effectively improves the internal connectivity of the venting assembly and enhances its venting performance.
[0051] The cooking utensils provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0052] Figure 3 This is a schematic diagram of the structure of an exhaust pipe assembly provided in an embodiment of this application. Figure 4 This is an exploded view of an exhaust pipe assembly provided in an embodiment of this application.
[0053] This application provides a cooking utensil 100, see [link]. Figure 1 and Figure 2 As shown, the cooking appliance 100 may also include an exhaust pipe assembly 130, which may be located between the inner shell 120 and the outer shell 110. For example, there may be a receiving space between the outer wall of the inner shell 120 and the inner wall of the outer shell 110, and the exhaust pipe assembly 130 may be located within the receiving space.
[0054] Combination Figure 3 and Figure 4 As shown, the exhaust pipe assembly 130 may include a straight pipe 131 and a bent pipe 132, wherein the straight pipe 131 and the bent pipe 132 may be separate components. The bent pipe 132 may include a first connector 1321 and a second connector 1322, and the opening directions of the first connector 1321 and the second connector 1322 may be angled. The first connector 1321 may be connected to the inner shell 120 and communicate with the cooking cavity, and the second connector 1322 may be connected to and communicate with one end of the straight pipe 131. The other end of the straight pipe 131 may communicate with the outside.
[0055] For example, the cooking appliance 100 may also include an exhaust duct 160, and the other end of the straight pipe 131 may be connected to the exhaust duct 160 so that the steam in the cooking cavity can enter the straight pipe 131 through the bent pipe 132 and enter the exhaust duct 160 from the straight pipe 131, and then be discharged to the outside through the exhaust duct 160.
[0056] For example, the first connector 1321 of the bend fitting 132 can be connected to the inner shell 120 by means of snap-fit, fastening, or threaded connection. The first connector 1321 of the bend fitting 132 is connected to the inner shell 120, that is, the opening direction of the first connector 1321 is perpendicular to the surface of the inner shell 120. Since the opening directions of the first connector 1321 and the second connector 1322 of the bend fitting 132 are set at an angle, this can effectively reduce the angle between the opening direction of the second connector 1322 and the surface of the inner shell 120. This angle can be small, or it can even be zero, that is, the opening direction of the second connector 1322 can be parallel to the surface of the inner shell 120. At this time, when one end of the straight pipe 131 is connected to the second connector 1322 and the other end extends between the inner shell 120 and the outer shell 110, the bending degree of the straight pipe 131 can be effectively reduced, which can effectively reduce or avoid the straight pipe 131 from being squeezed and deformed, and prevent the straight pipe 131 from being squeezed and deformed, thus affecting the gas exhaust effect in the cooking cavity, thereby effectively improving the exhaust effect of the exhaust pipe assembly 130.
[0057] This embodiment of the application includes a bend 132 and a straight pipe 131 that cooperate with each other in the exhaust assembly. The bend 132 can change the interface direction on the inner shell 120, which can reduce the angle between the opening direction of the second connector 1322 and the surface of the inner shell 120. When the straight pipe 131 is connected to the second connector 1322, it can effectively reduce or avoid bending of the straight pipe 131, thereby effectively preventing the straight pipe 131 from being squeezed due to bending, and preventing the straight pipe 131 from being squeezed and bent, which would cause internal blockage. This can effectively improve the internal connectivity of the exhaust pipe assembly 130 and improve the exhaust effect of the exhaust assembly.
[0058] Compared with the exhaust pipe structure with bends in related technologies, the straight pipe 131 in this embodiment can be a straight pipe structure without the need to be set as a structure with bends, which can effectively reduce the production difficulty of the straight pipe 131 and reduce the production cost of the straight pipe 131, thereby effectively reducing the overall production cost of the cooking appliance 100.
[0059] For example, in this embodiment, the bent pipe 132 can be a plastic part, and the straight pipe 131 can be a rubber tube. The bent pipe 132 can be formed by injection molding or other methods. This facilitates the preparation of the bent pipe 132, effectively reduces the difficulty of preparing the bent pipe 132, and thus reduces the overall production cost of the exhaust pipe assembly 130.
[0060] The angle between the first connector 1321 and the second connector 1322 can be different depending on the angle between the opening direction of the second connector 1322 and the surface of the inner shell 120.
[0061] For example, in this embodiment, the opening directions of the first connector 1321 and the second connector 1322 can be perpendicular. This allows the opening direction of the second connector 1322 to be parallel to the surface of the inner shell 120 when the first connector 1321 is connected to the inner shell 120. At this time, when one end of the straight pipe 131 is connected to the second connector 1322, the straight pipe 131 can also be parallel to the surface of the inner shell 120. When the straight pipe 131 extends within the accommodating space between the inner shell 120 and the outer shell 110, it can be extended without bending, effectively preventing compression deformation of the straight pipe 131, thereby effectively improving the unobstructed flow within the straight pipe 131 and enhancing the exhaust performance of the exhaust pipe assembly 130.
[0062] Figure 5 This is an exploded view of the fit between a pipe bend and a connector provided in an embodiment of this application. Figure 6 This is a cross-sectional view of a pipe bend and connector provided in an embodiment of this application.
[0063] See Figure 5 and Figure 6 As shown, the cooking appliance 100 may also include a connector 140. Part of the connector 140 may be located inside the inner shell 120, and another part of the connector 140 may be located outside the inner shell 120. The part of the connector 140 located outside the inner shell 120 may be connected to the bent pipe 132. The connector 140 and the bent pipe 132 may clamp the inner shell 120 to achieve the connection between the bent pipe 132 and the inner shell 120.
[0064] Specifically, the connector 140 may have a through hole 143, the connector 140 may be connected to the inner shell 120, and the through hole 143 on the connector 140 may communicate with the cooking cavity. The first connector 1321 of the bent pipe 132 may be connected to the connector 140, and the bent pipe 132 may communicate with the through hole 143.
[0065] For example, the connector 140 and the inner shell 120, as well as the bent pipe 132 and the connector 140, can be connected by means of adhesive bonding, snap-fitting, threaded connection, etc. The bent pipe 132 can communicate with the cooking cavity through the through hole 143 in the connector 140, so that the gas in the cooking cavity can enter the bent pipe 132 through the through hole 143, and then enter the straight pipe 131 through the bent pipe 132, and then be discharged into the exhaust duct 160 through the straight pipe 131.
[0066] The connector 140 facilitates the connection between the bend 132 and the inner shell 120, which can improve the reliability and stability of the connection between the bend 132 and the inner shell 120, thereby effectively improving the reliability and stability of the exhaust pipe assembly 130 in the cooking appliance 100.
[0067] For details, please refer to [link / reference]. Figure 5 and Figure 6 As shown, the inner shell 120 may have a connecting hole (not shown in the figure). The connector 140 may include a connected limiting part 141 and a second connecting part 142. The outer diameter of the limiting part 141 may be larger than the inner diameter of the connecting hole. The limiting part 141 may be located inside the inner shell 120 and abut against the inner shell 120. The second connecting part 142 may pass through the connecting hole and extend outside the inner shell 120. The first connector 1321 of the bent pipe 132 may be sleeved on the second connecting part 142 and connected to the second connecting part 142.
[0068] The bent pipe fitting 132 can be connected to the inner shell 120 through the cooperation with the second connecting part 142. The limiting part 141 can limit and fix the connecting part 140 to prevent the connecting part 140 from coming off the inner shell 120. This helps to improve the firmness and stability of the connecting part 140 on the inner shell 120, and improves the reliability and stability of the connection between the exhaust pipe assembly 130 and the inner shell 120, thereby effectively improving the structural stability of the cooking appliance 100.
[0069] See also Figure 5 and Figure 6 As shown, the cooking appliance 100 may further include a seal 150, which may be located between the first connector 1321 and the connector 140. The seal 150 provides a seal between the first connector 1321 and the connector 140. This effectively reduces or prevents steam leakage from the gap between the connector 140 and the bend 132, preventing steam leakage from damaging the components in the cooking appliance 100, thus improving the protection of the cooking appliance 100 and extending its service life.
[0070] See also Figure 5 and Figure 6 As shown, one of the other parts of the first connector 1321 and the connector 140 (i.e., the part of the connector 140 located outside the inner shell 120) may include a first limiting platform 1323 and a first connecting portion 1327 connected together. For example, the first limiting platform 1323 and the first connecting portion 1327 may be located on the first connector 1321, or the first limiting platform 1323 and the first connecting portion 1327 may also be located on the part of the connector 140 located outside the inner shell 120.
[0071] The other of the first connector 1321 and the other part of the connector 140 includes a second connecting portion 142. For example, the second connecting portion 142 may be located on the first connector 1321, or it may be located on the part of the connector 140 located outside the inner shell 120. The following description uses the example of the first limiting platform 1323 and the first connecting portion 1327 located on the first connector 1321, and the second connecting portion 142 located on the connector 140.
[0072] The first limiting platform 1323 can extend from the part connected to the first connecting part 1327 into the interior of the first connecting part 1327; that is, it can be understood that the first limiting platform 1323 protrudes radially inward from the inner wall of the first connecting part 1327.
[0073] The second connecting part 142 can be fixedly connected to the inside of the first connecting part 1327, and the second connecting part 142 and the first limiting platform 1323 respectively abut against the two ends of the sealing member 150.
[0074] This allows the seal 150 to be in a compressed state, which can effectively improve the tightness of the contact between the seal 150 and the first limiting platform 1323 and the second connecting part 142, and improve the sealing effect of the seal 150.
[0075] For example, in this embodiment, the first connecting portion 1327 and the second connecting portion 142 on the first connector 1321 can be connected by a threaded engagement. The threaded engagement is simple to operate, and the connection is firm and reliable, which facilitates the connection operation between the first connector 1321 and the connector 140, thereby effectively improving the reliability and stability of the connection between the bend fitting 132 and the connector 140.
[0076] See also Figure 5 and Figure 6 As shown, the bent pipe fitting 132 may further include a straight pipe section 1324. One end of the straight pipe section 1324 can be connected to the first connector 1321, and the other end can be connected to the second connector 1322. Furthermore, the extension direction of the straight pipe section 1324 can be consistent with the opening direction of the second connector 1322. That is, the extension direction of the straight pipe section 1324 is parallel to the surface of the inner shell 120. After the straight pipe fitting 131 is connected to the second connector 1322, it will also extend along the direction of the straight pipe section 1324, meaning the straight pipe fitting 131 will extend parallel to the surface of the inner shell 120. This effectively reduces the space occupied by the straight pipe section 1324 and the straight pipe fitting 131 between the inner shell 120 and the outer shell 110, thereby effectively reducing or avoiding bending and compression of the straight pipe fitting 131.
[0077] The straight pipe section 1324 facilitates the assembly between the straight pipe fitting 131 and the bent pipe fitting 132, reduces or avoids interference between the straight pipe fitting 131 and the first connector 1321 when they are fitted together, helps to improve the reliability of the connection between the straight pipe fitting 131 and the first connector 1321, and enhances the structural stability of the exhaust pipe assembly 130.
[0078] See also Figure 5 and Figure 6As shown, one of the outer periphery of the second connector 1322 and the inner wall of the straight pipe 131 may have a snap-fit portion 1325, and the other may have a snap-fit groove (not shown in the figure) that mates with the snap-fit portion 1325. For example, the outer periphery of the second connector 1322 may have a snap-fit portion 1325, and the inner wall of the straight pipe 131 may have a snap-fit groove. Alternatively, the outer periphery of the second connector 1322 may have a snap-fit groove, and the inner wall of the straight pipe 131 may have a snap-fit portion. In this embodiment, the example of the second connector 1322 having a snap-fit portion 1325 on its outer periphery and the straight pipe 131 having a snap-fit groove will be described.
[0079] The straight pipe fitting 131 can be sleeved onto the second connector 1322. For example, the straight pipe fitting 131 can be sleeved inside the second connector 1322, or the straight pipe fitting 131 can be sleeved outside the second connector 1322. In this embodiment, the straight pipe fitting 131 being sleeved outside the second connector 1322 is taken as an example. Furthermore, the snap-fit portion 1325 on the inner wall of the straight pipe fitting 131 can snap into the snap-fit groove.
[0080] The engagement between the snap-fit part 1325 and the snap-fit groove can limit the straight pipe fitting 131, so that the straight pipe fitting 131 and the second connector 1322 can be connected through the engagement between the snap-fit part 1325 and the snap-fit groove. This can effectively reduce or prevent the straight pipe fitting 131 from falling off the second connector 1322, thereby effectively improving the firmness and reliability of the connection between the straight pipe fitting 131 and the second connector 1322.
[0081] Alternatively, in some instances, the straight pipe fitting 131 and the second connector 1322 can also be connected by means of bonding, threaded connection, etc.
[0082] See also Figure 5 and Figure 6 As shown, the outer diameter of the straight pipe section 1324 can be larger than the outer diameter of the second connector 1322. The portion of the straight pipe section 1324 that is larger than the second connector 1322 can form a second limiting platform 1326, and the end of the straight pipe fitting 131 can abut against the second limiting platform 1326. The second limiting platform 1326 can limit the straight pipe fitting 131, which can reduce or avoid the straight pipe fitting 131 from moving or shifting on the second connector 1322, thus helping to improve the reliability of the fit between the straight pipe fitting 131 and the second connector 1322, and enhancing the stability of the connection between the straight pipe fitting 131 and the bend fitting 132.
