[0002] Ovens, steam ovens, steam boxes and other cooking devices are cooking machines that store food in a closed space and heat and cook the food. With the improvement of living standards, people have higher and higher performance requirements for cooking devices such as ovens and dishwashers.
[0003] In cooking devices such as ovens, steam ovens, and steam boxes, a cooking cavity is usually arranged inside the cooking device. During frequent use, the cooking cavity will gradually become dirty and difficult to clean, affecting the hygiene and safety of the product. Therefore, it is necessary to clean the inside of the cooking cavity after use or regularly.
[0004] In some related cooking devices, water cleaning is usually used to clean the cooking cavity. The water cleaning method requires that water is pumped into the cooking cavity through a cleaning pipeline, and the water after cleaning in the cooking cavity is discharged through a wastewater pipeline by the water pump. Therefore, two pipelines need to be arranged at the water outlet of the water pump. The on-off control method of the two pipelines is usually switched by two solenoid valves or an electric three-way valve, but it has high requirements on the sealing pressure of the valve body, and there is a leakage problem if the valve body is not matched properly.

[0008] The embodiments of the present invention have the following advantages and positive effects:
[0009] In the cooking device of the embodiment of the utility model, a first pipeline and a second pipeline are provided in the box, and the on-off of the first pipeline and the second pipeline is controlled by a switch control device. The switch control device includes a base and a cam. The first installation position and the second installation position are arranged in the base, and the first pipeline and the second pipeline are respectively arranged in the first installation position and the second installation position, and the cam is rotatably arranged between the first pipeline and the second pipeline. The first micro switch and the second micro switch are arranged on both sides of the cam. The cam rotates toward the first installation position, so that the cam can be against the first micro switch, and then the rotation angle of the cam in one direction can be accurately controlled, so that the first pipeline can be pressed between the cam and the side wall of the first installation position, so as to close the first pipeline and open the second pipeline.
