The invention discloses a safe microwave oven integrated machine with a food lateral-entering function. The safe microwave oven integrated machine comprises a food lateral-entering sliding-in device and a lateral-entering and forward-taking-out heating device, the food lateral-entering sliding-in device comprises automatic goods-delivering mechanisms, a cabinet body, food accommodating compartments and slide way mechanisms are further included, and the food accommodating compartments and the slide way mechanisms are both mounted inside the cabinet body, wherein the slide way mechanisms are located below outlets of the food accommodating compartments, and the automatic goods-delivering mechanisms are located in the food accommodating compartments. The lateral-entering and forward-taking-outheating device comprises furnace bodies, microwave generators, a front taking door, an emptying mechanism and lateral-entering doors. Inclined slide ways are connected between an intelligent goods-selling mechanism and lateral inlets of microwave ovens, and thus the purposes that food is selected by a consumer autonomously and subjected to microwave heating, and finally the heated food is obtained can be conveniently achieved. It can be completely and absolutely guaranteed that no foreign matter exists in the microwave ovens, thus whether the foreign matter exists or not does not need to be viewed specially and manually, extremely-high safety is achieved, and multi-entering and multi-taking-out effects can be further achieved.
