BACKGROUND OF THE INVENTION This invention relates to an air conditioner installed in a toll collection booth.

[0002]

2. Description of the Related Art Conventionally, as an air conditioner of this type, as shown in FIG. 3, it is installed on a booth ceiling 1 and comprises an air conditioner main body 2 for cooling and heating and an outdoor unit 3, and the air conditioner main body 2 has a heater. 4, an evaporator 5, a filter 6, and a blower fan (not shown) are provided. Further, the outdoor unit 3 is provided with an upper vent 7 on the upper side and a side vent 8 on the side, and the heat of the condenser 9 is passed from the upper vent 7 by a blower 12 including an impeller 10 and a motor 11. It is known that the gas is released to the outside through the partial ventilation port 8 (see, for example, Japanese Utility Model Application Laid-Open No. 49-12741).

[0003]

In the conventional air conditioner as described above, since the impeller 10 of the outdoor unit 3 faces the side vent holes 8, the amount of air discharged from the impeller 10 when the outside wind is strong. And the amount of heat transferred to the condenser 9 is insufficiently released, the air conditioning effect inside the booth is impaired, and the compressor (not shown) connected to the condenser 9 is destroyed in the worst case. .

The present invention has been made to solve the above-mentioned problems, and the heat is surely radiated from the condenser without being influenced by the outside air, the air conditioning in the booth is stable, and the outside air is utilized. The purpose is to obtain an air conditioner capable of energy saving air conditioning.

[0005]

An air conditioner according to the present invention comprises a booth, an outer casing provided on a ceiling of the booth, having an upper opening and a side opening communicating with each other at an upper portion and a side portion, A blower comprising an impeller arranged to face the side opening so as to form an air path from the upper opening to the side opening in the outer casing, and a motor equipped with the impeller, It is equipped with an air conditioner that adjusts according to the outside air from this blower and cools and heats the inside of the booth, and a wind speed sensor is provided in the outer casing, and an electric shutter linked with this wind speed sensor is provided in the side opening. It is a thing.

[0006]

In this invention, the booth, the outer casing provided on the ceiling of the booth and having the upper opening and the side opening communicating with each other at the upper portion and the side portion, and the upper opening in the outer casing. A blower composed of an impeller arranged facing the side opening so as to form an air path to the side opening and an electric motor equipped with the impeller, and adjusted by the outside air from the blower. The air conditioner for cooling and heating the inside of the booth is provided, and the wind speed sensor is provided in the outer casing, and the electric shutter interlocked with the wind speed sensor is provided at the side opening. The state is detected, and the electric shutter is driven by this detection.

1 to 3 are views showing an embodiment of the present invention, in which 15 is a booth for collecting charges, 16 is an outer casing of an air conditioner 17 installed on the ceiling of this booth, and 18 is An air conditioner provided in this outer casing includes a filter 19, an evaporator 20, a heater 21 for heating, and an air conditioner blower (not shown) for sending an air flow into the booth 15 via these.
Is installed inside. An outdoor unit 22 is provided in a room 23 separated from the air conditioner 18 and has an upper opening 24 at its upper portion and a side opening 25 at its side portion. Reference numeral 26 denotes a condenser, which is connected to the evaporator 20 to perform heat dissipation,
As shown in FIG. 2, it is arranged so as to face the side opening 25. 27 is a side opening facing the condenser 25
The blower is located between the above and the inside of the outdoor unit 22, and includes an electric motor 28 and an impeller 29 mounted on the electric motor and including, for example, a propeller fan. The impeller is directed to the side opening 25 side and forms an air passage from the upper opening 24 to the side opening 25. Reference numeral 30 is a partition inside the outer casing 16, 31 is a pipe for taking in the outside air of the air conditioner 18 and 32 is a wind speed sensor, which will be described later when detecting a wind speed of about 40 to 60% of the maximum wind speed generated by the blower 27. Signal to the control circuit. 33 is a control circuit, which detects the signal from the wind speed sensor 32,
The shutter drive unit, which will be described later, is driven, and when the signal from the wind speed sensor 32 disappears, the shutter drive unit is returned to the initial state. Reference numeral 34 denotes a shutter drive unit, which is composed of a geared motor, for example, and opens and closes an electric shutter 35 provided in the side opening 25. In this electric shutter, a plurality of shutter plates 36 are continuously provided at predetermined intervals via rods (not shown), and the rods are used for the shutter drive unit 34.
It operates in two ways: full open and 60 ° angle. This is used properly depending on the operation signal from the wind speed sensor 32, it is in the open state of 60 °, and when there is no operation signal, it is fully opened, and further to the electric shutter 35. It is fully closed when the power is turned off.

In the air conditioner configured as described above, the inside of the booth 15 is heated by the heater 21 and the air conditioner blower, while the evaporator 20, the condenser 26 and the air conditioner blower perform a cooling operation. Is done. In this case, the condenser 26 of the outdoor unit 22 is radiated by the blower 27, but when the outside air from the side opening 25 is strong, the electric shutter 3 is detected via the wind speed sensor 32 and the control circuit 33.
5 closes to an opening of 60 °, preventing the influence of the external wind on the impeller 29 in the cooling action. Further, when the operation of the air conditioner is stopped, the electric power to the electric shutter 35 is turned off.
When F is closed, it closes, so it is possible to prevent rainwater from entering. In this way, the cooling action is performed and stable performance is obtained without being affected by the outside wind.

[0009]

As described above, the present invention provides a booth, an outer casing provided on the ceiling of the booth, having an upper opening and a side opening that communicate with each other at an upper portion and a side portion, and inside the outer casing. At, a blower consisting of an impeller arranged facing the side opening so as to form an air passage from the upper opening to the side opening, and an electric motor equipped with the impeller,
It is equipped with an air conditioner that adjusts according to the outside air from this blower and cools and heats the inside of the booth, and a wind speed sensor is provided in the outer casing, and an electric shutter linked with this wind speed sensor is provided in the side opening. Therefore, when the outside wind to the side opening is strong, the electric speed shutter automatically operates the electric shutter, so that the outside air adjustment from the blower is stable, and stable and efficient cooling and heating can be always performed.
