Description

Steamer microwave oven integrated machine

Technical field

The invention relates to a kitchen appliance product, in particular to a steambox microwave oven integrated machine.

Background technique

With the continuous improvement of people's quality of life, kitchen appliances are becoming more and more abundant, microwave ovens, ovens, steamers, etc. have gradually become the kitchen appliances necessary for family life. These kitchen appliances have a single function and each product needs to occupy a certain space in the kitchen. In order to effectively utilize the kitchen space and enrich the use function of the individual products, at present, many microwave ovens with a steam function have appeared in the prior art, such as the one disclosed in Chinese Patent Application No. CN102331008A (Application No. 201110231072.3). Microwave, steam cooking dual-purpose microwave oven, which can directly heat food through microwave, and can steam food by steam generated by microwave heating water. Such microwave oven needs to place water container for generating water vapor. In the microwave oven cavity, but the volume of the microwave oven cavity is not large, the space is narrower after the special water container is placed, which makes the space for cooking food very effective, so the space utilization rate of the microwave oven cavity is low. Another example is a "steam-operated microwave oven" disclosed in Chinese Patent Publication No. CN201439958U (Patent No. ZL200920185932.2), which places a steamer in a microwave oven cavity, and then passes the steam generator outlet through a steam conduit and The steamer is connected. This method requires a steamer specially used for steaming food in the cavity of the microwave oven, which is not very convenient to use.

In order to overcome the shortcomings of the existing steam-operated microwave oven, a steamer microwave oven integrated machine has been invented, and a steam component and a microwave component are disposed in the casing of the integrated machine. When the steam function is used, steam generated by the steam component enters. In the cooking chamber cavity, when the microwave function is used, the microwave generated by the microwave component enters the cooking chamber cavity. Although the entire cooking chamber of the steamer microwave oven can be used as a cooking chamber of the steamer or as a cooking chamber of the microwave oven, the problem of low utilization of the cavity space is solved. However, since the steam component and the microwave component of the steamer microwave oven integrated machine each contain a plurality of components, the layout of the steam component and the microwave component in the current steamer microwave oven integrated machine is not reasonable enough, thereby resulting in the integrated machine.
