Embodiment
Execution mode 1
Fig. 1 is the synoptic diagram of the air conditioner involved by execution mode 1, and Fig. 2 is the end view of the internal structure of the outdoor unit schematically showing Fig. 1.
Air conditioner shown in Fig. 1 is made up of outdoor unit 100 and indoor unit 200, and this indoor unit 200 is connected with outdoor unit 100 via refrigerator pipe arrangement 300.This indoor unit 200 possesses indoor heat converter, forced draft fan etc., above-mentioned indoor heat converter plays a role as evaporator when cooling operation and plays a role as condenser when heating running, above-mentioned forced draft fan attracts room air, attracted room air and indoor heat converter is made to carry out heat exchange, then towards indoor blowout.
As shown in Figure 2, outdoor unit 100 possesses: forced draft fan 10, and this forced draft fan 10 is configured with fan 30 in exhaust outlet 101 side; Outdoor heat converter 40, this outdoor heat converter 40 is arranged at suction inlet 102 side; And heater 50, this heater 50 is arranged at the bottom side of outdoor unit 100.In addition, outdoor unit 100 possesses compressor, cross valve, expansion valve etc., and these parts are arranged at the refrigerant piping 300 of the ring-type be connected with indoor heat converter.Outdoor heat converter 40 plays a role as condenser when cooling operation and plays a role as evaporator when heating running.
Forced draft fan 10 is made up of motor 20 and fan 30, attracts extraneous air in the running from suction inlet 102, makes attracted extraneous air and outdoor heat converter 40 carry out heat exchange and then discharges from exhaust outlet 101.Motor 20 has the lining 60 for being drawn towards the outside by the wire 70 being arranged at inside, and is installed on support unit 103 via installation foot 29.When the defrosting running carrying out outdoor unit 100, heater 50 is energized.This heater 50 has following effect: namely, avoid the ice melted in defrosting running again become ice and block the discharge outlet being arranged at outdoor unit 100.
The structure of Fig. 3 and Fig. 4 to the motor 20 of above-mentioned forced draft fan 10 is used to be described.
Fig. 3 is the cutaway view of the Sketch of the motor of the forced draft fan that the outdoor unit being arranged at Fig. 2 is shown, Fig. 4 is the cutaway view of the state illustrated after the lining of the motor of Fig. 3 is coated with hydrophobic liquid.
Motor 20 is such as made up of brushless DC motor, possesses: the stator 21 of the cylindrical shape of outward appearance; The rotor 24 of cylindrical shape, this rotor 24 is configured in stator 21 centered by the axle center of stator 21; Bearing 26, the axle 25 at the center of through rotor 24 supports as rotatable by this bearing 26; Annular substrate 71, is provided with the position detecting element 72 of the position of rotation of detection rotor 24 at this substrate 71; Moulded resin 28, the outer peripheral face of this moulded resin 28 covering stator 21 and substrate 71 side; And support 27, this support 27 is chimeric with the opening of moulded resin 28, the one side of covering stator 21 and rotor 24 together with moulded resin 28.
Stator 21 is made up of stator core 22a, winding 22b and insulating part 23, and above-mentioned winding 22b is formed by coiled wires in the groove of stator core 22a, and above-mentioned insulating part 23 couples of stator core 22a and winding 22b insulate.Stator 24 uses permanent magnet.The lining 60 of the drum formed by resin material is inserted with in the face by heater 50 side of moulded resin 28.This lining 60 is outlets of wire 70, and this wire 70 is connected with substrate 71.
As shown in Figure 4, wire 70 is connected with winding 22b via substrate 71, to drive motor 20.This wire 70 is fixed by the moulded resin 28 between substrate 71 and lining 60.As shown in Figure 4, hydrophobic liquid 80 is coated with at this lining 60.Specifically, interface (contact-making surface) between the outer peripheral face and moulded resin 28 of lining 60, the interface (contact-making surface) between the inner peripheral surface of lining 60 and moulded resin 28, the moulded resin 28 in lining 60 and the interface (contact-making surface) between the outer peripheral face of wire 70, be coated with hydrophobic liquid 80.As this hydrophobic liquid 80, such as, use liquid silicon etc.
Herein, Fig. 5 is used to be described the unfavorable condition of carrying out when defrosting running.
Fig. 5 is the cutaway view in the intrusion path of the water illustrated in the lining of existing motor.
When carrying out heating running, the air of low temperature flows at outdoor heat converter 40 by forced draft fan 10, therefore, is attached with frost or ice at outdoor heat converter 40.Just implement defrosting running at regular intervals, in order to avoid cause performance to reduce because of the attachment of this frost or ice.
When carrying out defrosting running, in the mode making outdoor heat converter 40 play a role as evaporator, making cold-producing medium from compressor via in cross valve inflow outdoor heat exchanger 40, making the frost or the ice-out that are attached to outdoor heat converter 40.In addition, when carrying out defrosting running, the motor 20 of forced draft fan 10 stops, in order to avoid the frost melted or ice freeze again.Now, in outdoor unit 100, be in low-temperature condition, and become high humidity state because of the steam melting generation by frost or ice in outdoor unit 100.In addition, now, profit is attached to the frost of outdoor heat converter 40 or ice melts by heater 50 and produces steam, and therefore, outdoor unit 100 becomes the state of high humidity more.
Under the environment of this high humidity low temperature, produce condensation at the outline of motor 20 and the stator surface of inside.If defrosting running terminates and carries out heating running under the state that motor 20 creates condensation, then outdoor heat converter 40 is cooled sharp, occurs to freeze.If produce condensation like this and freeze, and this situation produces repeatedly, then moisture immerses the inside of motor 20, and as air conditioner, the action that generation motor 20 stops is bad.
