CONSTITUTION:A suction port, equipped with a suction grille 4, and a discharging port, equipped with a discharging frame 7, are formed up-and-down at the front surface of an indoor unit 3. An air flow passage, made by a casing 8, is formed in the indoor unit 3. An indoor heat exchanger 6 is arranged near the suction port while the discharging frame 7 is arranged below the heat exchanger 6. In this case, a plurality of vertical vanes 11, 12 and a plurality of horizontal vanes 13, 14 are arranged respectively at the discharging unit of the air flow passage. The direction of discharging air is regulated by the vertical vanes 11 by manual regulation while the vertical vanes 12 are integrated with the discharging frame. On the other hand, the up-and-down direction of the discharging air is controlled automatically by respective horizontal vanes 13, 14 while the pivotal shafts of these vanes are connected to an airflow direction deflecting plate motor.

摘要： PURPOSE:To enable always keeping the atmosphere comfortable by providing a means for changing the target temperature corresponding to a set temperature for bringing the temperature of the room to a desirable point and a means for changing the number of revolutions of an indoor fan according to the detected temperature of the room. CONSTITUTION:When the temperature of the room has fallen already of falls below (a set temperature + 0.25 deg.C) at the start 'SAWAYAKA' operation, the control of an indoor fan 15 shifts from weak wind to breeze. This shift prevents the room air from giving a chilly feel as its temperature falls close to the set point. The start is ended when the temperature of the room has reached a target temperature (= the set temperature) and a timer 12 has finished counting a preset time T. With the target temperature altered to (the set temperature + 0.25 deg.C) the operation shifts to a post-start routine. The increase in the target temperature causes the temperature of the room to rise, but since it is only by 0.25 deg.C that the target temperature has been increased, the compressor 16 keeps running although the rotation is at low speed and the temperature of the room, restrained from a rapid rise, increase slowly. The control of the indoor fan 15 shifts from breeze to light wind so as to free the people from a feeling of discomfort due to the rise in the temperature of the room.

摘要： PURPOSE:To enable a condensation water at a rear surface of a cabinet to be positively flowed into a water receptacle by a method wherein the rear surface of the cabinet is provided with several wedge-shaped ribs. CONSTITUTION:An extreme end 21 of each of ribs 19 is formed as a wedge so as to prevent a breakage of condensation of water. A water flowing surface of each of the ribs 19 is formed as a wedge-shaped rib 19, thereby the water flowing surface is eliminated and then a speed of the condensation water 20 is restricted positively. That is, the wedge-shaped ribs 19 cause the condensation water 20 formed at the rear surface 7 of the cabinet to be divided toward a direction of the wedge, resulting in that a water splashing caused by the breakage of the condensation water is prevented. In addition, the condensation water 20 is not flowed at the wedge-shaped extreme end 21, but the water is flowed positively between the wedge-shaped ribs 19 and then a restriction of a dropping velocity of water is positively carried out.

摘要： PURPOSE:To eliminate the impossibility and the like of operation due to complication of operation, missing of a card or an accident and make the operation control system of an air conditioner easy in handling and high in reliability by a method wherein the air conditioner is provided with an operating switch and a transmitting device outputting a predetermined operating pattern signal in conjunction with the operation of the switch. CONSTITUTION:An operating pattern, in which the rotating number of an indoor fan 4 is set at 'weak' mode, the maximum rotating number of a compressor 11 is set at the half of the normal rotating number thereof and the rotating number of an outdoor fan 10 at 'weak' mode, and other plurality of operating patterns are stored in a microcomputer in a main body control unit 2. When the operating switch 6 of a remote control unit 5 is operated by a customer, the summary of the selected operating pattern is indicated in an indicating unit 7 and a signal to carry out the operating pattern is outputted from a transmitting unit 9. When a receiving unit 3 receives the signal, the main body control unit 2 sets the indoor fan 4 at 'weak' mode, sets the maximum rotating number of the compressor 11 at the half of the rotating number of the same upon normal operation, sets the rotating number of the outdoor fan 10 at 'weak' mode and operates respective machines. When the receiving unit does not receive the signal, the normal operation of the air conditioner may be effected.

摘要： PURPOSE:To prevent dusts or insects from entering an air conditioner, make a rational eddy flow of a through-pass fan and improve a blowing performance by a method wherein a front surface of an ornamental cover is divided into a plurality of rotatable louvers and a suction port of each of the louvers is cooperatively operated with a discharging angle of an air directing plate. CONSTITUTION:An ornamental cover 2 is divided into a plurality of louvers 2' and cooperated with a link 7 with a blowing air directing motor 6. An independent rotating motor is provided to make a relation with the blowing direction plate 5. In case of termination of operation, either the motor 6 or independent motor is rotated to close the port so as to cause the louvers of the suction port to be seen as one panel. Accordingly, it is possible to prevent dusts or insects from entering the louvers of the suction port. In addition, in a system in which a front surface of the air conditioner is constructed to show a panel-like appearance, an aeration resistance is reduced during cooling or heating operation and in case that the user changes freely the blowing air direction plate and the louvers are rotated at the suction port so as to increase an efficiency, resulting in that a superior efficient air conditioner can be provided.

摘要： PURPOSE:To set noise constant during the sweeping operation to prevent corrugated sound from being generated by controlling the speed of a motor for variable speed blasting for driving an indoor fan in linkage with the position of a vertical vane and that of a horizontal vane. CONSTITUTION:A motor 1 for variable speed blasting is controlled of its speed depending on the time of turning ON of a triac 5. The ON timing of the triac 5 is determined by a fan control signal of a control microcomputer 11. Further, a vertical vane 4 is driven by a driving motor 3, and carries out horizontal autosweeping by the command from a control microcomputer 11. A delay time of a fan control signal 13 from the control microcomputer 11 for driving the motor 1 for variable speed blasting is, in linkage with the position of the vertical vane 4, further delayed so that from a predetermined time in which the rotational speed of an indoor fan 2 when the vertical vane is set at the front position is obtained so that the rotational speed of the indoor fan 2 at which the noise is not increased depending on the position of the vertical vane 4.

摘要： PURPOSE:To reduce the up-and-down fluctuation of a room temperature, by a method wherein a set temperature is corrected by the detecting temperature of a sensor at the side of a remote controller while the operation of an air-conditioning machine is controlled by the corrected temperature and the detecting temperature of the sensor at the side of a main body, when the wireless remote control system air-conditioning machine is controlled. CONSTITUTION:A receiving unit receives an optical signal and effects the editing of data. The detecting temperature of a sensor at the side of a remote controller in the edited data and a set temperature are sent to a temperature difference operating unit. A room temperature detector converts the electric resistance value of a main body side sensor 331 into a temperature and sends it to a temperature difference operating unit as a main body side sensor detecting temperature. The temperature difference operating unit operates a temperature difference between the remote controller side sensor detecting temperature and the main body side sensor detecting temperature and corrects a set temperature by adding the temperature difference to the set temperature, further, operates a difference between the corrected temperature and the main body side sensor detecting temperature to send it to an operation control unit. The operation control unit obtains the rotating number of a compressor from the value and commands the value to an outdoor control unit through an interface unit.
