[ 1-1-2. Structure of substrate Main body ]
As shown in fig. 1, electrical components 25 are mounted above the machine room 18. The electrical component 25 includes a substrate body 30 on which a predetermined conductive pattern is formed.
As shown in fig. 2 and 3, the substrate main body 30 is disposed substantially parallel to the spacer 16 at a predetermined interval.
Various electronic components such as a transistor, a capacitor, and a resistor are mounted on the substrate main body 30.
In the present embodiment, two current wires 31, 31 on the primary side are connected to the substrate main body 30. The current wiring 31 has both ends connected to predetermined terminals 32 of the board body 30 by soldering (welding). Further, the terminal 32 may be fixed by a screw or a snap terminal.
The current wiring 31 has a longer wire length with respect to the distance between the terminals 32. Therefore, in a state where the current wiring 31 is connected to the terminal 32, the current wiring 31 is held in an arc shape in a state where the central portion thereof is separated from the substrate main body 30.
The current wiring 31 is, for example, a current wiring 31 for passing a large current to the compressor 24 and the like.
The current wiring 31 is provided with current sensors 40 and 40, respectively. The current sensor 40 includes an annular core 42 having a hole 41 formed in the center thereof. The current wiring 31 is disposed to pass through the hole portion 41 of the core 42 of the current sensor 40.
Then, the core 42 of the current sensor 40 is fixed to the current wiring 31 by a holding member 43 such as a tie or an adhesive tape.
The current sensor 40 includes a sensor wire 44.
A connector 33 for a sensor is mounted between terminals 32 of the substrate main body 30 to which the current wiring 31 is connected. The sensor wires 44 of the two current sensors 40 are connected to the connector 33.
The sensor wires 44 of the two current sensors 40 are collected by an adhesive tape (tape, band) 45 so as not to contact the surface of the substrate main body 30.
A label 46 indicating a mark for identifying the current sensor 40 and a direction of current to the core 42 is attached to the outer peripheral surface of the core 42 of the current sensor 40.
A front panel 50 (see fig. 6) covering the substrate main body 30 is provided on the front surface side of the substrate main body 30.
Fig. 4 is an explanatory diagram illustrating the core 42 of the current sensor 40. Fig. 5 is an explanatory diagram showing a relationship between the current wiring 31 and the current sensor 40. Fig. 6 is an explanatory diagram showing a relationship between the current sensor 40 and the substrate main body 30.
As shown in fig. 4, the inner radius of the core 42 of the current sensor 40 is d1, the outer radius of the core 42 is d2, and as shown in fig. 5, the height from the primary-side wiring to the substrate at the position where the core 42 is fixed is h. As shown in fig. 6, the diameter of the primary-side current line 31 is set to beThe distance between the front panel 50 and the substrate main body 30 is H.
In this case, the spatial distance m1 between the outer peripheral surfaces of the substrate main body 30 and the core 42 is:
therefore, h is determined so as to ensure m1 > 0, and is adjusted according to the length of the primary-side current wiring 31 or the connection position to the substrate main body 30.
The spatial distance m2 between the substrate main body 30 and the front panel 50 is:
m2=H-h-d1-d2。
therefore, H is determined so as to secure m2 > 0, and H is adjusted according to the length of the primary-side current wiring 31 or the connection position to the substrate main body 30.
[ 1-2. actions ]
Next, the operation of the outdoor unit 1 configured as described above will be described.
When the outdoor unit 1 starts operating, the blower 23 starts to be driven to rotate. By the rotational driving of the blower 23, the outside air flows into the heat exchange chamber 17 through the outdoor heat exchanger 22, exchanges heat with the outdoor heat exchanger 22, and is discharged to the outside of the outdoor unit.
When the substrate main body 30 fails, the substrate main body 30 is replaced entirely.
That is, in the present embodiment, both ends of the current wiring 31 are connected to one substrate main body 30, and the sensor wiring 44 of the current sensor 40 through which each current wiring 31 is inserted is also connected to the connector 33 of the same substrate main body 30.
Therefore, when the substrate main body 30 is replaced, the operation of detaching the connection of the current wiring 31 and the operation of detaching the sensor wiring 44 of the current sensor 40 are not required.
[ 1-3. Effect, etc. ]
As described above, the present embodiment includes the substrate main body 30 and the electronic component disposed on the substrate main body 30, and includes the current sensor 40, the current sensor 40 includes the annular core 42, the connector 33 and both end portions of the current wiring 31 passing through the core 42 are connected to one substrate main body 30, and the connector 33 is connected to the sensor wiring 44 of the current sensor 40.
Thus, when the substrate main body 30 is replaced, the operation of detaching the connection of the current wiring 31 and the operation of detaching the sensor wiring 44 of the current sensor 40 are not required. Therefore, when the substrate main body 30 is replaced, it is possible to suppress occurrence of a connection error in the new substrate main body 30, an error in the mounting direction of the current sensor 40, and the like.
In the present embodiment, the current sensor 40 is fixed to the current wiring 31 by the holding member 43.
This can suppress movement of the current sensor 40 with respect to the current wiring 31.
In the present embodiment, two current wires 31 are provided, and one connector 33 is connected to the sensor wires 44 of the current sensor 40 provided on each of the two current wires 31.
This allows the sensor wires 44 of the current sensors 40 to be collectively provided.
In the present embodiment, the height position of the current wiring 31 is set so as to ensure a spatial distance between the substrate main body 30 and the outer peripheral surface of the core 42.
This can prevent the outer peripheral surfaces of the substrate main body 30 and the core 42 from coming into contact with each other. Therefore, the current sensor 40 can be prevented from contacting the substrate main body 30 and causing a short circuit or the like.
In the present embodiment, a front panel 50 covering the surface of the substrate main body 30 is provided, and the height position of the current wiring 31 is set so as to secure a spatial distance between the front panel 50 and the outer peripheral surface of the core 42.
This can prevent the front panel 50 from contacting the outer peripheral surface of the core 42. Therefore, the current sensor 40 can be prevented from contacting the front panel 50 and causing a short circuit or the like.
