[0041] This application provides a cooking device with the function of steaming food, such as a steam-baking air fryer.

[0042] Combination Figure 1 and Figure 2The cooking apparatus 1000 includes a pot body 200 and a lid assembly 100. The pot body 200 has a cooking cavity 201, and the lid assembly 100 is movably connected to the pot body 200 to open or close the cooking cavity 201. When the lid assembly 100 opens the cooking cavity 201, it allows a user to place or remove food from the cooking cavity 201; when the lid assembly 100 closes the cooking cavity 201, the cooking apparatus 1000 can process the food. The movable connection method between the lid assembly 100 and the pot body 200 is not specifically limited in this embodiment. Optionally, the lid assembly 100 is generally a flattened cylinder, and a portion of the lid assembly 100 is rotatably connected to the pot body 200 on its circumferential direction. Thus, the lid assembly 100 can be flipped relative to the pot body 200 about the axis at the connection point, achieving a flip-top opening and closing operation. Of course, the lid assembly 100 and the pot body 200 can also be connected by a rotating opening or a detachable connection.

[0043] Understandably, to achieve steaming of food, the cooking device 1000 is equipped with a steam generating component. Optionally, the steam generating component is integrated into the lid assembly 100, or it can also be disposed on the pot body 200; this embodiment does not limit this. When closed, the lid assembly 100 has a vent 35 on its inner wall facing the cooking cavity 201. The vent 35 is fluidly connected to the inner cavity of the steam generating component to spray steam into the cooking cavity 201. However, after the cooking device 1000 has finished operating, some steam may still remain in the steam pipe used to deliver steam. When the lid assembly 100 is opened, the remaining steam continues to spray out from the vent 35, posing a risk of steam inhalation and burns.

[0044] To solve the above problems, please refer to the following: Figures 1 to 3 The pot lid assembly 100 proposed in this application includes a lid body 10, a steam generating assembly, and a steam venting assembly 30. The steam generating assembly is installed inside the lid body 10, and the steam venting assembly 30 is connected to the steam generating assembly. The steam generating assembly is used to generate steam, and the steam venting assembly 30 is connected to the inner cavity of the steam generating assembly for venting steam. The steam venting assembly 30 can be connected to the lid body 10 and has a steam vent 35 exposed on one side of the lid body 10. Specifically, the steam vent 35 is exposed on the side of the lid body 10 facing the cooking cavity 201 when the lid body 10 is closed, so that steam can flow into the cooking cavity 201 through the steam vent 35.

[0045] In this embodiment, the axial direction of the vent 35 is angled to the axial direction of the lid assembly 100. The axial direction of the vent 35 represents its orientation, and the steam flowing out of the vent 35 generally moves along the axial direction of the vent 35. Combined with... Figure 2The axial direction S of the lid assembly 100 is the direction that passes through the lid assembly 100 along its thickness. For some flip-top cooking appliances 1000, when the lid assembly 100 is opened, its pivot point is generally located on the side of the cooking appliance 1000 away from the user. During opening, the axial direction S of the lid assembly 100 may directly face the user. The technical solution of this application, by setting the axial direction of the vent 35 at an angle to the axial direction of the lid assembly 100, ensures that the flow direction of the steam exiting the vent 35 is also at an angle to the axial direction of the lid assembly 100. Thus, when the lid assembly 100 is opened, the steam will not flow directly towards the user along its axial direction, but will flow in another direction at an angle to the axial direction of the lid assembly 100, thereby avoiding direct steam impact on the user, preventing the risk of burns, and improving the safety of using the lid assembly 100.

[0046] For example, in Figure 2 and 3 In the illustrated embodiment, when the lid assembly 100 is opened, the axial direction of the vent 35 is generally downward. This ensures that during the opening process, the steam flowing from the vent 35 always flows downward towards the lid assembly 100, rather than directly towards the user, effectively preventing steam burns and improving safety. Alternatively, when the lid assembly 100 is opened, the axial direction of the vent 35 can also be generally oriented to the side of the lid assembly 100 to prevent steam from escaping directly forward.

[0047] In some embodiments, the lid 10 includes a lid body 11 and a protective cover 13. The protective cover 13 is disposed on the side of the lid body 11 facing the cooking cavity 201 when closed, to protect the internal components of the lid assembly 100. A venting assembly 30 is connected to the lid body 11, and a vent 35 is exposed outside the protective cover 13.

[0048] Please refer to the details. Figure 3 The venting assembly 30 includes a venting component 33 and a steam vent pipe 31. The steam vent pipe 31 is connected to the steam generating assembly and has a steam outlet 311 at one end. The venting component 33 is sealed to the end of the venting assembly 30 with the steam outlet 311 and is partially located outside the protective cover 13. A vent hole 35 is located on the portion of the venting component 33 outside the protective cover 13. The venting component 33 has a venting channel 3331 that connects the steam outlet 311 and the vent hole 35. In this embodiment, the venting assembly 30 is formed by combining the venting component 33 and the steam vent pipe 31, which facilitates connection to the steam generating assembly and also facilitates setting the direction of the vent hole 35, thus facilitating production and assembly. By extending part of the venting component 33 out of the protective cover 13, steam can be easily discharged, and the vent hole 35 can have a larger included angle relative to the axial direction of the lid assembly 100, further preventing steam injury.

[0049] Optionally, the steam generating assembly and the steam outlet pipe 31 can be spaced apart, with the steam outlet pipe 31 fixed to the cover 10, and the steam generating assembly and the steam outlet pipe 31 connected by a pipe. Figure 3 In the illustrated embodiment, the steam outlet pipe 31 is a rigid pipe, which can be made of materials such as nylon. It is lightweight yet possesses sufficient structural strength and can withstand high temperatures. One end of the steam outlet pipe 31 has a connecting protrusion 313. One end of the gas pipe is fitted onto the connecting protrusion 313, and the other end is connected to the steam generating assembly. The cooperation between the connecting protrusion 313 and the gas pipe improves the connection stability between the steam outlet pipe 31 and the gas pipe, making the gas pipe less prone to detachment. Of course, the steam outlet pipe 31 can also be directly connected to the steam generating assembly; this embodiment does not limit this.

[0050] In some embodiments, the steam outlet pipe 31 is connected to the cover 10 via a snap-fit ​​connection. Specifically, the cover body 11 has a snap-fit ​​position 115, and the steam outlet pipe 31 is provided with a retaining plate 315 extending circumferentially, which is snapped into the snap-fit ​​position 115. For example, the cover body 11 has at least two snap-fit ​​members arranged opposite each other, the space between the at least two snap-fit ​​members can be flexibly varied in size, and the retaining plate 315 is arranged in a ring and snapped between the at least two snap-fit ​​members. Furthermore, the retaining plate 315 and the snap-fit ​​position 115 may also be provided with guide slopes to facilitate assembly, which will be described in more detail here. The connection between the steam generating assembly and the cover 10 via a snap-fit ​​connection facilitates disassembly, assembly, and maintenance, thus improving work efficiency. Of course, the steam outlet pipe 31 can also be connected to the cover body 11 by bolts or other methods to improve the connection strength.

[0051] Combination Figure 3 In one embodiment, the cover body 11 is provided with a connecting groove 111, and a protective cover 13 is provided on one side of the cover body 11, covering the opening of the connecting groove 111. The protective cover 13 is provided with a clearance hole communicating with the connecting groove 111. The steam outlet pipe 31 is connected to the cover body 11, and the air guide 33 includes a fixed part 331 and an air guide part 333 connected together. The fixed part 331 is provided in the connecting groove 111 and is sealed to one end of the steam outlet pipe 31 with a steam outlet 311. The air guide part 333 passes through the clearance hole and is partially located outside the protective cover 13. The air outlet 35 is provided in the air guide part 333, and the air guide part 333 defines at least the air guide part 3331 to allow steam to flow out through the steam outlet 311, the air guide channel 3331, and the air outlet 35.

[0052] Optionally, one of the bottom wall of the connecting groove 111 and the fixing part 331 is provided with a limiting ring 113, and the other is provided with a limiting groove 3311. The limiting ring 113 and the limiting groove 3311 are engaged in a limiting fit. For example, the bottom wall of the connecting groove 111 is provided with a limiting ring 113, which protrudes from the bottom wall of the connecting groove 111 and is located on the outer periphery of the steam outlet pipe 31. The outer periphery of the fixing part 331 forms a limiting groove 3311. The limiting ring 113 and the limiting groove 3311 engage in a limiting fit, allowing the fixing part 331 to be installed within the connecting groove 111. Thus, the engagement of the limiting ring 113 and the limiting groove 3311 not only improves the positional stability of the fixing part 331 within the connecting groove 111 and ensures a sealing effect, but also plays a positioning role during the assembly process of the fixing part 331, which is beneficial for improving assembly efficiency. Optionally, the axis of the steam outlet pipe 31 is not on the same straight line as the axis of the fixing part 331, thereby enabling error prevention during the assembly of the fixing part 331.

[0053] Of course, the fixing part 331 can also be installed in the connecting groove 111 by means of adhesive or screw fixing, and this application embodiment does not limit this.

[0054] Please refer to the reference. Figure 3 In one embodiment, the fixing part 331 is provided with a sealing channel 3313 through which the steam outlet pipe 31 passes, and a portion of the steam outlet pipe 31 passes through the sealing channel 3313. A sealing protrusion 3315 is provided on the channel wall of the sealing channel 3313, and the sealing protrusion 3315 abuts against the outer wall surface of the steam outlet pipe 31. In this embodiment, the portion of the steam outlet pipe 31 is located within the sealing channel 3313, increasing the contact area between the steam outlet pipe 31 and the fixing part 331, which is beneficial to improving the sealing effect. The sealing protrusion 3315 protrudes from the channel wall of the sealing channel 3313, thereby making the sealing protrusion 3315 and the portion of the steam outlet pipe 31 located within the sealing channel 3313 more tightly connected, further improving the sealing effect and effectively preventing steam from flowing out of the sealing channel 3313.

[0055] Furthermore, at least two sealing protrusions 3315 are provided on the channel wall of the sealing channel 3313. For example, in Figure 3 In the embodiment shown, three sealing protrusions 3315 are spaced apart along the extension direction of the sealing channel 3313 to achieve layer-by-layer isolation of steam, effectively preventing steam from flowing out through the sealing channel 3313 and affecting other components of the pot lid assembly 100, thereby improving the structural reliability of the pot lid assembly 100.

[0056] In some embodiments, the fixing part 331 is a rubber part or a soft rubber part. For example, the fixing part 331 is entirely made of rubber, and its elasticity allows it to better fit the connecting groove 111 and the steam outlet pipe 31, improving the sealing effect. Furthermore, the air guiding part 333 is an integral structure with the fixing part 331, and the air guiding part 333 can also be made of rubber or a soft rubber part. This improves the sealing and air guiding effect while being convenient, fast, and low in cost.

[0057] Combination Figure 3 The gas guiding channel 3331 is connected to the sealing channel 3313, and the steam outlet pipe 31 is located within the sealing channel 3313, thus connecting the steam outlet 311 to the gas guiding channel 3331. Notably, in one embodiment, the flow cross-sectional area of ​​the sealing channel 3313 is larger than that of the gas guiding channel 3331, forming a sealing step at the connection between the sealing channel 3313 and the gas guiding channel 3331. The gas outlet assembly 30 is spaced apart from the sealing step to define a buffer gap 335. Understandably, the larger flow cross-sectional area of ​​the sealing channel 3313 allows for a tight fit with the steam outlet pipe 31, and the flow cross-sectional area at the buffer gap 335 is also larger than that of the steam outlet 311. Thus, the pressure of the steam flowing from the steam outlet 311 into the buffer gap 335 is reduced, and the sealing step partially obstructs and turbulents the steam, which helps to increase the pressure loss of the steam, preventing excessive pressure of the steam discharged from the outlet 35, and further preventing steam from spraying out and causing injury. In addition, the buffer gap 335 can also provide a buffer margin for the installation of the steam outlet pipe 31, avoiding structural damage.

[0058] Steam within the buffer gap 335 flows to the outlet 35 via the air guide channel 3331. In some embodiments, the flow cross-sectional area of ​​the air guide channel 3331 is larger than that of the steam outlet 311 in a section perpendicular to the axial direction of the steam outlet 311. This slows down the steam flow rate and reduces the pressure as it enters the air guide channel from the steam outlet 311, preventing the steam from exiting the outlet 35 from flowing too fast and further improving safety.

[0059] Optionally, the extending direction of the air guide channel 3331 is set at an angle to the axial direction of the air outlet 35. In such cases... Figure 2 and Figure 3In the illustrated embodiment, the axial direction of the air guide channel 3331 is parallel to the axial direction of the steam outlet 311, and further, the axial direction of the air guide channel 3331 and the axial direction of the steam outlet 311 can be on the same straight line. In this embodiment, the air guide channel 3331 extends along the length of the air guide portion 333, and the air outlet 35 is provided on the side wall of the portion of the air guide portion 333 located outside the cover 10. Thus, the axial direction of the air outlet 35 is set at an angle to the axial direction of the air guide channel 3331. On the one hand, this changes the direction of the steam at the air outlet 35, preventing the steam from flowing out of the air outlet 35 at too high a speed. On the other hand, the channel wall of the air guide channel 3331 can also prevent the droplets formed by the liquefaction of steam from being sprayed out directly, avoiding scalding the user and further improving the safety of the cooking device 1000.

[0060] For example, the axial direction of the vent 35 is perpendicular to the axial direction of the lid assembly 100. Thus, in an embodiment where the surface of the protective cover 13 facing the cooking cavity 201 is perpendicular to the axial direction of the lid assembly 100, the vent 35 is oriented approximately parallel to the surface of the protective cover 13, and the steam flowing from the vent 35 flows along the surface of the protective cover 13 towards the side of the lid assembly 100. In this embodiment, the axial direction of the vent 35 is perpendicular to the axial direction of the lid assembly 100, ensuring that the steam flowing from the vent 35 avoids the user as much as possible, while also preventing the steam from continuously spraying towards the protective cover 13. Instead, the steam flows out to the side of the lid assembly 100 under the guidance of the protective cover 13, thereby improving both safety and structural reliability.

[0061] like Figure 3 As shown, in one embodiment, the air guide 33 is provided with an air-blocking edge 3333 spaced apart from the cover 10. The air-blocking edge 3333 is located at least on the side of the air outlet 35 away from the cover 10, so as to block the movement of airflow in the direction away from the cover 10, thereby better preventing the steam flowing out of the air outlet 35 from rushing directly to the user, and guiding the steam to the side of the air guide 33, further improving safety.

[0062] Optionally, the air baffle edge 3333 extends circumferentially at the end of the air guide 33, and the end of the air guide 33 forms a conical surface that connects to the air baffle edge 3333, so that it can pass through the clearance hole 131 during the assembly process of the air guide 33, thereby improving assembly efficiency.

[0063] The above is an exemplary explanation of the pot lid assembly 100 in the embodiments of this application. The cooking device 1000 proposed in the embodiments of this application adopts all the technical solutions of all the above embodiments, and therefore has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.
