The kitchen electrical products not only have single functions, each product needs to occupy certain kitchen space, but also are separately purchased with high cost. In order to make efficient use of kitchen space and reduce purchase costs, all-in-one machines have been disclosed in the prior art that integrate the functions of a steam box with a microwave oven and/or an oven.

For example, a micro steaming and baking integrated machine disclosed in chinese patent No. 201320074461.4 (No. CN 203168920U), includes a body, a door frame and a controller installed on a front surface of the body, a cavity is provided in the body, a transformer is installed on a top of the body, a capacitor connected to the transformer, a magnetron connected to the capacitor, a waveguide box connected to the magnetron, microwaves are transmitted into the cavity through the waveguide box, a microwave stirrer is provided at a microwave inlet in the cavity, a low speed motor is connected to the microwave stirrer, a water container and a steam generator connected to the water container are installed on a side wall of the body, the steam generator is communicated with the cavity in the body, a heating pipe is provided on a top of the cavity in the body, and the heating pipe is connected to the controller. For example, in the integrated steam box and microwave oven disclosed in chinese patent application No. 201510457051.1 (application publication No. CN 105011740 a), a steam inlet is provided in a cooking chamber, and the steam inlet is communicated with a steam outlet of a steam generating device. As disclosed in chinese patent No. 201410167732.X (publication No. CN 103976641B), the steam outlet at the top of the evaporator of the steam box is communicated with the steam inlet at the back of the inner container, and the steam generated from the evaporator enters the inner container.

In the prior art, no matter the functions of the steam box and one or two of the microwave oven and the oven are combined together, a water tank is required to be placed in an electric appliance to provide high-temperature steam for a cooking space. Especially, in an embedded cooking appliance, the water tank is often placed above the cooking cavity, and a panel which can be opened and closed is arranged on the front side surface of the cooking appliance to cover the water tank. Because receive cupboard installation space's influence, the panel need be forward or the side direction is opened and just can take out the water tank, if the panel side direction is opened, then can make cooking appliance's use occupy great space, if the panel directly pushes out to the front side, then can lead to the inboard water tank of panel to be not convenient for get and put.
