EXAMPLES Next, the present invention will be explained based on examples. 1 to 5 show an embodiment of the present invention. Reference numeral 100 denotes a self-propelled air conditioner, which is a dolly 1 and an air conditioner 2 mounted on the dolly 1.
And a remote control device 3.

The bogie 1 includes a front wheel 11 and two rear wheels 12 mounted on a lower surface of a machine frame 10, a direction changing means 13 for the front wheel 11, and a driving motor 14 for the front wheel 11 and the direction changing means 13. And its drive control device 15. A skirt 16 is attached to the outer periphery of the machine frame 10, and an approach sensor 17 is attached to the front portion of the skirt 16. Further, a general terminal 18 for fuel gas, a refrigerant and electricity is attached to a rear portion of the lower surface of the machine frame 10, and a flexible general pipe 4 is connected to the terminal 18. Furthermore, in the center of the machine casing 10,
A downward conditioned air suction port 21 is provided, and an air purifier 5 including an air filter is attached to the suction port 21.

The air conditioner 2 is mounted in a spherical shell-shaped air conditioner case 6 mounted on the upper part of the carriage 1. An air conditioning duct 20 which is a flow path of conditioned air is provided in the case 6. In the air-conditioning duct 20, a central duct 61 having the suction port 21 is provided in the vertical direction at the center of the case 6, and an upper end connecting duct 62 spreading like an umbrella,
It is connected to an annular outer duct 63 arranged coaxially outside the center duct 61, and has a tip (lower end) of the outer duct 63.
Is connected to a cylindrical surface-shaped outlet 22 opened on the outer periphery of the lower portion of the case 6. Connection duct 62 and outer duct 6
A heat insulating material 64 is stretched on the outer side surface of 3.

As shown in FIG. 3, the integrated pipe 4 is made of pressure-resistant rubber and has a fuel gas passage 41, an electric wire 42, and a refrigerant passage 43 therein.
Are formed in parallel. In this embodiment, the air conditioner 2 includes the air purifier 5, the gas heating device 7, and the cooling device 8.
Consists of. The air purifier 5 has an air filter and an electrostatic air purifier, and an air blower 71 provided above the air purifier 5 in the central duct 61 and a blower attached to the center of the ceiling of the connecting duct. Blower 7
The air sucked into the air conditioning duct 20 is purified by 3.

The heating device 7 comprises the intake blower 71, a gas burner 72, which is a heater, and the blower blower 73 mounted above the intake blower 71. The gas burner 72 is provided with an ignition device and a combustion control device, which is a heating control device that controls ignition, switching of combustion amount, and stop of combustion. In addition, the combustion control device incorporates a safety device that detects abnormal combustion such as oxygen deficiency or misfire and automatically stops the combustion. In this heating device, a part of the air sucked into the air conditioning duct 20 by the intake blower 71 is used as combustion air, and the burner 72 burns the fuel gas. Then, the air is blown from the air outlet 22 to the entire circumference of the case 6 to perform heating.

The cooling device 8 is an evaporator 81 mounted in the outer duct 63 in the vicinity of the blowout port 22 and a condenser, which is an outdoor unit connected through the integrated pipe 4,
It consists of a compressor and a cooling control device (neither shown). This air conditioner is provided with the conditioned air sucked into the duct 20 by the intake blower 71 and the blower blower 73.
It is cooled by the evaporator 81 and blown out from the blowout port 22 in the entire circumferential direction. In each case, the blower is 1
However, in order to keep the noise level of the blower low and to obtain a sufficient air volume, it is desirable that the number be two.

The remote controller 3 comprises a remote controller 9, a control signal receiver 31 installed in the case 6, an antenna 32 projecting from the upper end of the case 6, and a front wheel 11. Motor 1 for driving the direction changing means 13
No. 4 drive control device 15, a combustion control device (not shown) that controls the operation of the blowers 71 and 73, and the gas burner 72, and a control device of the cooling device 8 that includes the blowers 71 and 73 and an external unit (see FIG. (Not shown) and the blowers 71, 73 and the air purifier 5 including an electrostatic air purifier.

The remote controller 9 controls the motor drive control device to move the self-propelled heater 100 forward, backward, rightward,
An operation piece 91 for turning left, a selective operation switch 92 for heating, cooling, and air purification, and a set temperature switch 93 for warming and cooling are provided. The user selects this switch 92, 9
3 or the operation piece 91 can be operated to make the self-propelled air conditioner 100 self-propelled at a desired position and perform a desired air conditioning operation. When the self-propelled air conditioner 100 approaches a person or an object too much, the proximity sensor 17 detects these obstacles and causes the air-conditioning stop, backward movement, avoidance behavior, warning, or other necessary operation for safety.

Although the air conditioner having the cooling / heating function has been described in the above embodiment, the air conditioner may have only the heating function or the cooling function. The fuel for heating is not limited to gas, but electricity or oil can be used. Further, the cooling device may be of a type in which the evaporator, the compressor, the condenser, and the refrigeration cycle of the expansion valve are all mounted, and cool air is blown in a predetermined direction and hot air is blown in another direction.
