Description

Technical Field

[0001] This utility model relates to the field of cooking appliance technology, specifically to a duct switching device for a multifunctional cooking appliance. Background Technology

[0002] Multifunctional cooking appliances typically combine the convenience of air fryers and steamers, thus fulfilling various cooking needs.

[0003] To facilitate user operation and broaden the applicability of cooking equipment, some existing technologies utilize a shared channel structure for the air vents of air fryers and the steam outlets of steaming pots. While this solution addresses the need to remove excess heat and exhaust steam to some extent, in steaming mode, water vapor and liquids entering the channel structure are difficult to clean, easily leading to bacterial growth and odors, affecting the hygiene and lifespan of the equipment. Furthermore, in air fryer mode, the seals within the channel structure obstruct the flow of hot air, resulting in uneven heating of the food and impacting cooking quality. Moreover, the seals are exposed to high temperatures for extended periods in air fryer mode, accelerating their aging and potentially causing failure. In severe cases, this can lead to hot air leakage, increasing the risk of equipment malfunction and safety hazards, thus requiring further improvement in user experience. Utility Model Content

[0042] This embodiment is basically as shown in the appendix. Figure 1 -Appendix Figure 13 As shown:

[0043] A multifunctional cooking appliance air duct switching device includes a top cover assembly 100, on which a hot air outlet 101 and a steam outlet 102 are provided; in actual use, the top cover assembly 100 is adapted to be installed on the cooking body (not shown in the figure), and the cooking body has a cooking cavity to accommodate the food to be cooked.

[0044] The top cover assembly 100 is provided with a baffle 110 and a drive assembly 200. The baffle 110 is arranged at the hot air outlet 101. The drive assembly 200 has a knob 210. The drive assembly 200 is driven by the knob 210 to move the baffle 110, thereby opening or closing the hot air outlet 101, that is, corresponding to the cooking mode selection of air fryer and steaming.

[0045] In this embodiment, the upper cover assembly 100 includes an air duct plate 120, a hot air outlet 101 and a steam outlet 102 located on the air duct plate 120, and the cross-sectional area of ​​the hot air outlet 101 is larger than the cross-sectional area of ​​the steam outlet 102; the drive assembly 200 is adapted to be installed on the air duct plate 120.

[0046] A bracket 130 is provided on the air duct plate 120, and a rotating shaft 131 is rotatably arranged on the bracket 130. The baffle 110 is installed on the rotating shaft 131 and rotates with the rotating shaft 131. The bracket 130 is fixed to the air duct plate 120 by matching screws. Preferably, the cross-sectional shape of the rotating shaft 131 is generally D-shaped to achieve a fixed assembly between the baffle 110 and the rotating shaft 131, that is, to achieve the rotation of the baffle 110 with the rotating shaft 131.

[0047] In the above technical solution, the drive assembly 200 includes a meshing drive gear 220 and a driven gear 230; the drive gear 220 is rotatably supported on one side of the bracket 130, and the driven gear 230 is coaxially connected to the end of the rotating shaft 131, and the driven gear 230 rotates synchronously with the rotating shaft 131; the knob 210 is connected to the edge of the drive gear 220 to drive the drive gear 220 to rotate.

[0048] Furthermore, one end of the dial 210 has a mounting groove 211, and the drive gear 220 has an extended connecting portion 221, which is connected to the mounting groove 211. Specifically, the mounting groove 211 is located at the lower end of the dial 210, and the connecting portion 221 is located at the edge of the upper part of the drive gear 220. During installation, the connecting portion 221 is inserted into the mounting groove 211, and the connecting portion 221 and the mounting groove 211 are connected and fixed by suitable screws or bolts.

[0049] To optimize the structure and layout of exhaust hot air and water vapor, in the above technical solution, an exhaust hood 140 is installed on the duct plate 120. The exhaust hood 140 has an air outlet 141 and a steam outlet 142. During installation, the exhaust hood 140 is installed on the duct plate 120 using appropriate screws.

[0050] Baffle 110 is located within the space enclosed by air outlet hood 140, and is arranged between hot air outlet 101 and air outlet 141. An exhaust passage 103 connects steam outlet 102 and steam outlet 142. Preferably, the exhaust passage 103 is arranged at an angle, that is, it is arranged at an angle downward from the outer edge of air outlet hood 140 to steam outlet 102. To improve the sealing, a suitable silicone part is provided between exhaust passage 103 and steam outlet 102.

[0051] Specifically, the air outlet hood 140 is provided with an isolation section 143 to divide the area inside the air outlet hood 140 into two areas, with the baffle 110 located in one area and the exhaust passage 103 located in the other area.

[0052] A micro switch 150 is adapted and installed inside the top cover assembly 100. The micro switch 150 is used to connect to the control board with electrical signals to control the operating mode of the cooking appliance. The drive gear 220 is provided with a trigger part 222. The contact 151 on the micro switch 150 is located on the moving path of the trigger part 222. That is, during the rotation of the drive gear 220, the trigger part 222 can abut or press the contact 151 to operate the micro switch 150.

[0053] In this embodiment, the micro switch 150 is arranged on one side of the air outlet shroud 140, and the micro switch 150 is connected to the air outlet shroud 140 using a matching screw.

[0054] A housing 160 is mounted on the air duct plate 120. The main structure of the drive assembly 200 is located in the space between the air duct plate 120 and the housing 160. The top of the dial 210 extends out of the housing 160. A travel slot 161 for the dial 210 to move is provided on the housing 160.

[0055] The baffle 110 is provided with a flexible sealing element 111, which is used to form a seal with the hot air outlet 101 after deformation to block the flow of air. Specifically, the flexible sealing element 111 is provided on the inner side of the baffle 110, and preferably, the sealing element 111 is a silicone part.

[0056] In specific usage environments, the cooking mode of the cooking appliance can be selected according to actual needs, thereby meeting different cooking requirements.

[0057] When the air fryer mode is needed, the dial 210 is moved toward the center of the upper cover assembly 100. The dial 210 converts the relative linear motion into the rotation of the drive gear 220. The drive gear 220 drives the driven gear 230 to rotate. The driven gear 230 drives the baffle 110 to flip through the rotating shaft 131, so that the seal 111 on the baffle 110 separates from the hot air outlet 101 at a certain angle. In this embodiment, the preferred angle is 45°. At this time, the trigger part 222 on the drive gear 220 leaves the micro switch 150. At this time, the contact 151 on the micro switch 150 loses the pressure or contact of the external force. The micro switch 150 transmits the corresponding electrical signal to the control board to switch the working mode of the cooking appliance to the air fryer mode. The hot air generated in the cooking cavity can be discharged out through the hot air outlet 101 and the air outlet 141 in sequence.

[0058] When the steam cooker mode is needed, the reverse movement of the dial 210 drives the drive gear 220 and driven gear 230 to rotate, which in turn drives the baffle 110 to return to the hot air outlet 101 via the rotating shaft 131. At this time, the seal 111 on the baffle 110 closes and seals the hot air outlet 101 based on compression deformation. At this time, the trigger part 222 on the drive gear 220 presses down on the contact 151 and triggers the micro switch 150. The micro switch 150 then transmits the corresponding electrical signal to the control board to switch the working mode of the cooking appliance to the steam cooker mode. The water vapor generated during cooking is discharged sequentially through the steam outlet 102, the exhaust channel 103, and the steam port 142.

[0059] It should be noted that in this embodiment, the other internal structures of the cooking appliance and their corresponding control structures are existing technologies, and their structures and principles will not be described in detail here.

[0060] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
