The invention provides a heat preservation drawer. The heat preservation drawer comprises an outer cavity assembly which is a hollow cavity body with an open end, a cavity body assembly which can be arranged in the hollow cavity in a sliding mode, a stove door assembly arranged at one end of the cavity body assembly, sliding rail assemblies arranged on the outer cavity assembly and the cavity body assembly, and sliding lock assemblies arranged on the sliding rail assemblies and used for locking the stove door assembly when the cavity body assembly slides into the hollow cavity body and opening the stove door assembly when the stove door assembly is pressed, wherein relative sliding of the outer cavity assembly and the cavity body assembly is achieved through the sliding rail assemblies. By arranging the sliding lock assemblies on the sliding rail assemblies, when the stove door assembly is in a closed state, the stove door assembly is locked by locking assemblies to make the cavity body in a sealed state, and the heat preservation effect of the heat preservation drawer is ensured. When the stove door assembly needs to be opened, the locking assemblies are pressed to open locking structures, the stove door assembly is opened, opening and closing of the stove door assembly are achieved, and the heat preservation drawer is simple in structure and easy to operate.
