Description

Technical Field

[0001] The utility model relates to the technical field of steam ovens, in particular to an exhaust structure of a steam oven. Background Art

[0002] A steam oven is a kitchen appliance that can both steam and bake, and can also support steam baking. The origin of domestic steam ovens was borrowed from the steam ovens in Western Europe. Since the IFA Consumer Electronics Show in Berlin, Germany began to add the white appliance section in 2008, domestic white appliance companies have often taken the initiative or been invited to participate in IFA. During this period, white appliance brands such as Midea and Haier discovered that steam ovens have huge potential for the domestic market, so they began to study the feasibility of combining steaming and baking into one cooking method.

[0003] Existing steam ovens are generally provided with an exhaust structure to achieve the hot air function and steam exhaust function. For example, Chinese patent publication number CN113854848A discloses a "hot air exhaust structure of a steam-bake combination oven". A movable shielding member is installed in the air guide cover on the outer wall of the inner pot. In the steam mode, the movable shielding member moves to a position that covers the hot air holes on the inner pot and opens the air outlet holes, and connects the air outlet holes with the air outlet on the top of the air guide cover. Steam is discharged from the exhaust port through the air outlet on the top of the air guide cover. In the grill mode, the movable shielding member moves to a position that opens the hot air holes and closes the air outlet holes, and disconnects the hot air holes from the air outlet, preventing heat from dissipating from the air guide cover. In this way, the hot air function and steam exhaust function can be achieved using the same mechanism.

[0004] However, in actual use, since oil smoke will also be discharged during the steam exhaust process, the fan blades of the exhaust structure will be attached with oil smoke and other dirt after long-term use, affecting the exhaust and intake effects. The existing exhaust structure is usually fixed with screws, which is not convenient to disassemble for cleaning and replacement. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art that the fan blades of the exhaust structure will be attached with oil smoke and other dirt after long-term use, and the existing exhaust structure is usually fixed with screws, which is inconvenient to disassemble for cleaning and replacement. A steam oven exhaust structure is proposed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A steam oven exhaust structure is designed, comprising an air guide assembly connected to the oven, the air guide assembly being provided with a mounting opening, the mounting opening being rotatably provided with fan blades, the air guide assembly being connected to a motor via a connecting structure, the output shaft of the motor being fixedly connected to the fan blades;

[0008] The wind guide assembly includes a mounting plate, an upper cover is provided on the mounting plate, and air guide grooves are provided on both the mounting plate and the upper cover, and the fan blades are rotatably provided between the upper cover and the mounting plate;

[0009] The connection structure includes a mounting bracket, the motor is fixedly connected to the mounting bracket, and the mounting bracket is clamped to the upper cover.

[0010] Furthermore, a support ring is fixedly provided on the mounting frame, a connecting groove is provided on the support ring, and a clamping piece that matches the connecting groove is fixedly provided on the upper cover.

[0011] Furthermore, a plug-in plate is fixedly provided on the support ring, and the plug-in plate is plugged into the clamping member.

[0012] Furthermore, one end of the clamping member protrudes upward to form a guide portion, and one side of the guide portion has a slope.

[0013] Furthermore, the clamping member is provided with a recessed portion, and the inserting plate is provided with a clamping slot that matches the recessed portion.

[0014] Furthermore, a heat insulation plate is provided between the mounting plate and the upper cover, and the fan blades are provided between the heat insulation plate and the upper cover.

[0015] The steam oven exhaust structure proposed in the utility model has the following beneficial effects:

[0016] In the present invention, the motor is fixedly connected to the mounting bracket, which is then clamped to the upper cover. By rotating the mounting bracket to separate the connecting groove from the clamp, the mounting bracket can be removed. When the mounting bracket is removed, the motor and fan blades can also be removed, making it easy to clean and replace. When installing, the mounting bracket can be rotated in the opposite direction, achieving quick installation and removal.

[0017] Secondly, in the present invention, a card slot that cooperates with the recessed portion is provided on the plug plate. When the mounting frame is connected to the upper cover, the mounting frame is rotated in the opposite direction so that the plug plate and the card member are plugged in until the card slot is engaged with the recessed portion, and the installation is completed. The engagement of the card slot with the recessed portion can prevent the mounting frame from rotating accidentally and falling off, thereby playing a fixing role. BRIEF DESCRIPTION OF THE DRAWINGS
