BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a heating and cooling appliance, especially to a heating and cooling appliance for use in a vehicle. [0003] 2. Description of the Prior Arts [0004] When people drive or take trips in vehicles, people often bring hot drinks or cold drinks onto the vehicles. The hot drinks and the cold drinks quickly approach ambient temperature in the vehicles unless placed in a heating or cooling appliance. However, heating chests and portable refrigerators occupy a large volume in vehicles. [0005] To overcome the shortcomings, the present invention provides a heating and cooling appliance for use in a vehicle to mitigate or obviate the aforementioned problems. SUMMARY OF THE INVENTION [0006] The main objective of the present invention is to provide a heating and cooling appliance for use in a vehicle. The heating and cooling appliance for use in a vehicle has an outer box, a thermal box, an inner box, at least one semiconductor chip and at least one heatsink assembly. The outer box is mounted in the vehicle to conform to interior equipment and furnishings of the vehicle and has a switch. The thermal box is mounted in the outer box and has multiple insulated walls and at least one heat-conducting wall. The inner box is mounted in the thermal box. The semiconductor chip is attached to the heat-conducting wall and connected electrically to the switch on the outer box. The heatsink assembly is attached to the semiconductor chip and mounted securely on the thermal box. Changing the position of the switch will change the operating mode of the semiconductor chip to either heat or cool the heat-conducting wall and the contents of the inner box. [0007] Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS [0008] FIG. 1 is a perspective of a heating and cooling appliance for use in a vehicle in accordance with the present invention with four drink cans; [0009] FIG. 2 is a partially exploded perspective view of the heating and cooling appliance in FIG. 1 with four drink cans; [0010] FIG. 3 is an exploded perspective view of the heating and cooling appliance in FIG. 1 without the outer box and with four drink cans; [0011] FIG. 4 is a side view in partial section of the heating and cooling appliance in FIG. 1; [0012] FIG. 5 is an operational perspective view of a vehicle interior with two heating and cooling appliances in FIG. 1 mounted in the vehicle; and [0013] FIG. 6 is a top view of a vehicle interior with three heating and cooling appliances in FIG. 1 mounted in the vehicle. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [0014] With reference to FIGS. 1, 2 and 3, a heating and cooling appliance for use in a vehicle in accordance with the present invention comprises an outer box (10), a thermal box (20), an inner box (30), at least one semiconductor chip (40) and at, least one heatsink assembly (50). [0015] With further reference to FIGS. 5 and 6, the outer box (10) is mounted in a vehicle to conform to interior equipment and furnishings of the vehicle and has a top, four sides, an inner space, an opening, a switch (11) and at least one vent (12). The outer box can be an armrest, a bucket seat console or the like. The opening is formed in the top and communicates with the inner space. The switch (11) is mounted on the top and can be pressed to turn off the heating and cooling appliance or activate either a heating mode or a cooling mode. The at least one vent (42) is formed uniquely in a side. [0016] The thermal box (20) is hollow, is mounted in the inner space through the opening in the outer box (10) and has four outer sidewalls, a top opening, a top edge, multiple insulated walls (21) and at least one heat-conducting wall (22). The insulated walls (21) are formed in the outer sidewalls. Each heat-conducting wall (22) is formed in an insulated wall (21) and corresponds uniquely to a vent (12). [0017] The inner box (30) is hollow, is mounted through the top opening in the thermal box (20) and has a top opening, a top edge, an outer sidewall, an optional flange (31) and an optional fluid passage (32). The flange (31) is formed on and extends out perpendicular from the top edge of the inner box (30) and attaches to the top edge of the thermal box (20). The fluid passage (32) is formed around the outer sidewall of the inner box (30) and is filled with a heat-conducting fluid. [0018] Each semiconductor chip (40) is attached uniquely to a heat-conducting wall (22), corresponds to the fluid passage (32), electrically connects to the switch (11) and has an inside surface, an outside surface and heatsink grease (41). The inside surface is attached to the heat-conducting wall (22). The heatsink grease (41) is spread on the outside surface. Changing the position of the switch (11) will change the operation mode of the semiconductor chip (40). When the switch (11) is in the closed position, the semiconductor chip (40) stops operating. When the switch (11) is the heating position, the semiconductor chip (40) generates heat. When the switch (11) is in the cooling position, the semiconductor chip (40) cools. [0019] With further reference to FIG. 4, each heatsink assembly (50) is attached to the outside surface of the corresponding semiconductor chip (40), is mounted securely on the corresponding heat-conducting wall (22) and has a heatsink fin assembly (51) and a fan (52). The heatsink fin assembly (51) is attached to the outside surface of the semiconductor chip (40), is attached to the corresponding heat-conducting wall (22) and has a base (511) and multiple fins (512). The base (511) is attached to the outside surface of the semiconductor chip (40), is attached to the corresponding heat-conducting wall (22) and has an inside surface and an outside surface. The inside surface is attached to the outside surface of the semiconductor chip (40). The fins (512) are formed on the outside surface of the base (511) and have a distal end. The fan (52) is mounted securely on the distal end of the fins (512) and electrically connects to the switch (11). When the switch (11) is in the heating position, the fan (52) blows heat from the fins (512) out the vent (12). [0020] The heating and cooling appliance as described has numerous advantages. The outer box (10) conforms to the interior equipment and furnishings of the vehicle and does not occupy unnecessary spaces. The switch (11) can change the operation way of the semiconductor chip (40). Then the semiconductor chip (40) can give out heat or cold as the user wish. When the heating and cooling appliance has multiple semiconductor chips, and the inner box has the fluid passage so the heating or cooling effects will be distributed evenly.
