 at least one first fixing element attached to the front frame; and 
   at least one fixing device configured to mechanically fix the built-in cooking appliance to the furniture unit,   wherein the at least one first fixing element forms part of the at least one fixing device for fixing the built-in cooking appliance to the furniture unit,   wherein the at least one first fixing element of the at least one fixing device is configured to cooperate with a second fixing element of the at least one fixing device such that, when the built-in system is in an installed state, the built-in cooking appliance is disposed in the installation niche and fixed to the furniture unit by the at least one fixing device,   wherein the at least one fixing device comprises a latching device,   wherein the at least one the first fixing element comprises a first latching element,   wherein the second fixing element comprises a second latching element, and   wherein the at least one the first fixing element and the second fixing element are configured and arranged to match each other such that, when the built-in cooking appliance is moved in an installation direction to transfer the built-in system to the installed state, the at least one first latching element comes into latching engagement with the second latching element such that the built-in cooking appliance is held to the furniture unit along the installation direction when the built-in system is in the installed state.   
     
     
         2 . The built-in system of  claim 1 , wherein the at least one first latching element has a peg and the second latching element is configured as a catch corresponding to the peg, or
 wherein the at least one first latching element comprises a catch and the second latching element has a peg corresponding to the catch.   
     
     
         3 . The built-in system of  claim 2 , wherein the peg and the catch are configured to match each other, such that the peg, which is connected to the catch when the built-in system is in the installed state, is disengageable by a removal force acting in a direction opposite to the installation direction. 
     
     
         4 . The built-in system of  claim 2 , wherein the peg and the catch are configured and arranged to match each other so as to compensate for tolerances. 
     
     
         5 . The built-in system of  claim 1 , wherein the at least one first latching element comprises a plastic part. 
     
     
         6 . The built-in system of  claim 2 , wherein, in a plan view, the peg comprises an acute-angled wedge at a free end of the peg. 
     
     
         7 . The built-in system of  claim 2 , wherein the catch comprises a spring having two lateral spring arms, the spring arms being configured to latchingly cooperate with the peg when in engagement therewith. 
     
     
         8 . The built-in system of  claim 7 , wherein the base plate comprises markings to assist in the attachment of the catch to the furniture unit. 
     
     
         9 . The built-in system of  claim 1 , wherein the built-in system is configured such that, when the built-in system is in the installed state, the latching device is completely invisible to a user of the built-in cooking appliance, even when the cooking chamber door of the built-in cooking appliance is open. 
     
     
         10 . The built-in system of  claim 1 , wherein the built-in system is configured for toollessly transferring the built-in system to the installed state and for toollessly transferring the built-in system to a removed state of built-in system. 
     
     
         11 . The built-in system of  claim 4 , wherein the peg and the catch are configured to compensate for tolerances perpendicular to the installation direction. 
     
     
         12 . The built-in system of  claim 11 , wherein the catch is oversized compared to the peg along a vertical axis to such an extent that the peg is securely held in the catch, despite any tolerances along the vertical axis. 
     
     
         13 . The built-in system of  claim 5 , wherein the at least one first latching element is releasably attached to the front frame. 
     
     
         14 . The built-in system of  claim 13 , wherein the at least one first latching element is attached to the front frame by latching connections. 
     
     
         15 . The built-in system of  claim 6 , wherein, in a top view, the acute-angled wedge merges into a constriction of the peg on both sides thereof in a direction toward a root of the peg, the transition comprising an obtuse-angled wedge, and the catch being configured to correspond to the peg. 
     
     
         16 . The built-in system of  claim 7 , wherein the two lateral spring arms are disposed on a central base plate of the catch for attachment of the catch to the furniture unit or to the front frame. 
     
     
         17 . The built-in system of  claim 16 , wherein the catch comprises a single-piece sheet-metal member. 
     
     
         18 . The built-in system of  claim 8 , wherein one catch for holding a peg when the built-in system is in the installed state is provided on each side of the built-in cooking appliance on a side panel of the furniture unit, the markings being arranged so as to assist in installing the built-in cooking appliance centrally between two side panels of the furniture unit. 
     
     
         19 . The built-in system of  claim 18 , the markings are suitably arranged for side panels having wall thicknesses of at least one of 16 mm and 19 mm. 
     
     
         20 . The built-in system of  claim 9 , wherein the latching element associated with the front frame is attached to the front frame such that the latching element is disposed behind a front panel of the built-in cooking appliance in a viewing direction of the user.
