Coffee machine

The utility model relates to a coffee machine which comprises a lower machine body. The upper machine body is arranged on the lower machine body and is provided with an extraction box for placing an object to be extracted; the upper machine body is restrained on the lower machine body in the mode that the upper machine body can slide front and back relative to the lower machine body. The extraction box of the upper machine body at least has a storage state in which the extraction box of the upper machine body moves to a position right above the lower machine body and a use state in which at least part of the extraction box of the upper machine body deviates out of the vertical projection of the lower machine body. Due to the fact that the upper machine body is restrained on the lower machine body in the mode that the upper machine body can slide back and forth relative to the lower machine body, when the storage state and the use state are switched, the upper machine body does not occupy too much operation sp
