Description

Technical Field

[0001] The invention relates to a steam-bake all-in-one machine, and in particular to a hot air exhaust structure of the steam-bake all-in-one machine. Background Art

[0002] As people's quality of life continues to improve, kitchen appliances are becoming more and more abundant, and microwave ovens, ovens, steamers, etc. have gradually become essential kitchen appliances for family life. These kitchen appliances not only have relatively simple functions, but each product needs to occupy a certain kitchen space, and the cost of purchasing them separately is high. In order to effectively utilize the kitchen space and reduce the purchase cost, people have invented a steamer, oven, and microwave oven all-in-one. For example, the "A Steamer, Oven, and Microwave Oven All-in-One" disclosed in the Chinese invention patent application with application number 201611206944.X (application publication number CN108236354A) has a hot air baffle on the back of the cooking chamber cavity, an air inlet and an air outlet are opened on the hot air baffle, a hot air chamber is provided on the back of the hot air baffle, a heating assembly is installed in the hot air chamber, and the hot air chamber is connected to the cooking chamber cavity through the air inlet and the air outlet. The all-in-one machine also includes a first air duct and a second air duct. The wind from the air outlet of the first air duct quickly cools down the magnetron, the high-voltage fuse and the high-voltage capacitor. The air outlet of the second air duct is connected to the outside of the box. During operation, the hot air generated by the components of the steam generator is taken away by the cross-flow fan and discharged to the outside of the box through the second air duct. It can be seen that the all-in-one machine needs to install the air duct and the hot air chamber in a limited space, which increases the component space and needs further improvement in structure.

[0013] As a preferred embodiment of any of the above solutions, a steam inlet is provided on the inner container, and the steam generated by the external steam generating device enters the inner container through the steam inlet.

[0014] Compared with the prior art, the advantage of the present invention is that the hot air exhaust structure of the steam-bake machine is equipped with a movable shielding member 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 covering the hot air holes on the inner pot and opening the air outlet holes, and makes the air outlet holes communicate with the air outlet port on the top of the air guide cover, and the steam is discharged from the exhaust port through the air outlet port on the top of the air guide cover. In the grilling mode, the movable shielding member moves to a position opening the hot air holes and closing the air outlet holes, and makes the hot air holes disconnected from the air outlet port, thereby preventing heat from dissipating from the air guide cover. In this way, the hot air function and the steam exhaust function can be realized by using the same mechanism, which greatly reduces the component space and increases the efficiency of the mechanism.
