A mobile solar and liquefied petroleum gas mixing oven according to the present invention, comprising a oven structure (1) in the form of a metal frame having a left and right side view in the form of a triangle mounted on a stove base (5), which is a rectangular structure mounted on a stand with wheels (2) at the lower end of each stand; wherein the oven structure (1) has two side walls (33), the left and right sides in the form of triangles made of transparent materials at all points supporting the use of solar energy as the primary heat source; wherein the side walls (33) have ventilation fans (3) installed at both bottom corners of the side walls (33) and ventilation vents (4) installed at both top corners of the side walls (33); the stove base (5) supports the installation of a gas stove set (11) at all points supporting the use of liquefied petroleum gas as an auxiliary heat source. Whereas the upper part of the gas stove set (11) is inside the stove structure (1), and the lower part of the gas stove set (11) is outside the stove structure (1) to connect to the system control panel, flame igniter (13) and gas supply control valve (17). The stove structure (1) at the front and back has a metal frame supporting the glass lid (34) on both sides in the shape of a trapezoid made of transparent material at all points to support the use of solar energy as the main heat source. The glass lid (34) has a base structure that is longer than the upper structure, where the hinged pivot point is installed on the upper structure of the glass lid (34). Every point supports the opening of the glass lid (34) by lifting the base structure upwards, and every point supports the closing of the glass lid (34) by lifting the base structure downwards. The area inside the stove structure (1) which is closed by the side walls (33), the glass lid (34), and the stove bottom (5) to support a heat source that is a mixture of solar energy as The main heat source together with liquefied petroleum gas as an auxiliary heat source, where, outside the stove structure (1) at the bottom of the gas stove set (11), there is an additional main control panel (12) which is connected to the gas stove set (11). The main control panel (12) consists of a temperature and humidity display and setting panel (20) located at the upper left corner, which displays and sets the target temperature and target humidity of the area. Inside the stove structure (1), there is a convection fan operation status indicator light (21) located at the lower left corner near the gas stove operation status indicator light (22). There is a humidity control switch (23) installed above the heat dissipation control switch (24) located below the temperature and humidity display and setting panel (20). There is a convection fan speed adjustment button (25) installed at the bottom. Convection fan timer (26), with an automatic shutdown timer (27) installed on the right side of the convection fan timer (26), and an exhaust fan delay timer (28) installed below the mode selection switch (29). The glass cover (34) is opened by lifting the base structure upwards. Every display shows the assembly details of the hot air circulation system equipment for the interior space. The oven structure (1) On the top part of the oven floor (5), a number of oven racks (6) are provided to support the ingredients to be baked. On the top of the gas burner unit (11), which is inside the oven structure (1), there is a left-hand convection fan (7), which circulates heat from the gas burner unit (11) to circulate inside the oven structure (1), using the left-hand air direction control panel (8) to control the air flow direction. On the right side of the gas burner unit (11), there is a right-hand convection fan (9), which circulates heat. The heat from the gas stove set (11) is circulated inside the stove structure (1).
