Description
Technical field
The present invention relates to the off-premises station of air conditioner, relate in particular to and improved the off-premises station of air conditioner of controller architecture that the circuit board of electrical equipment is equipped with in folding and unfolding.
Background technology
The off-premises station of general divergence type (split type) air conditioner, folding and unfolding has the blower fan of compressor, heat exchanger, relative configuration with this heat exchanger etc. in its framework, and the folding and unfolding of packing into is useful on the controller of circuit board that compressor, blower fan etc. is driven the electrical equipment of control.On the shell of this controller, be equipped with through hole, circuit in the controller is connected with blower fan with compressor (with reference to patent documentation 1: Japanese patent laid-open 9-60928 communique by the lead (lead wire) that passes this through hole, paragraph [0036], Fig. 1, Fig. 4).
In addition, general electrolytic capacitor, electrolyte wherein be just in case the occasion that spills because of a certain reason, produces discharge and this liquid is caught fire and make the capacitor burning from the lead of the high-tension circuit portion in the electric element box or fan electromotor and compressor, although this possibility is minimum, but exist.
As long as there is such possibility of catching fire to exist, just need take to tackle such countermeasure of catching fire and taking place.In the patent documentation 1, as countermeasure, the electric element box that will comprise electrolytic capacitor is the morphosis of following integral body to cover with metal base plate of controller, even spilling also can be stoped by this base plate from electrolytic capacitor, electrolyte catches fire, even just in case catch fire, also can prevent to spread, so that fire extinguishing immediately to other parts.
But, because of patent documentation 1 is that shell with the morphosis electric element box that covers with metallic plate is the shell integral body of controller, its metallic plate is very big, and utilizes the opening that the sheet metal punching is configured for connecting up, the peristome that is used to ventilate etc., so it adds and can produce leftover pieces man-hour, the material use rate variance in addition, also will spend leftover pieces handling etc., and, must be when assembling operation with lead by through hole, operating efficiency is poor, also has the long shortcoming of lead.
Summary of the invention
The present invention can provide a kind of off-premises station with air conditioner of following feature.That is,
A kind of off-premises station of air conditioner comprises: the blower fan of compressor, heat exchanger, relative configuration with this heat exchanger, and folding and unfolding be useful on the controller of the circuit that described compressor and blower fan are controlled, it is characterized in that,
Described controller comprises: conductor terminal and electrolytic capacitor are housed below and constitute the circuit board of described circuit; This circuit board is surrounded and the supporting mass of the frame shape that keeps; Cover the top of described circuit board and be installed in sheet metal system panel on described supporting mass top; And on form covering below described circuit board described the zone of described electrolytic capacitor is housed and vacate the zone that described conductor terminal is housed shape, be installed in the sheet metal system base plate on described supporting mass following.
According to the off-premises station of air conditioner of the present invention, can provide a kind of and have the stock utilization height, need not spend disposal cost etc., element manufacturing and the wiring of leftover pieces the operating efficiency height, do not need the off-premises station of air conditioner of controller of the structure of long lead.

The specific embodiment
Below, describe with reference to the example of accompanying drawing the off-premises station of air conditioner of the present invention.
Fig. 1 is the stereogram that a part of framework of the off-premises station of air conditioner of the present invention is dissectd expression, and Fig. 2 amplifies the stereogram of expression with the controller of Fig. 1 and outer part thereof.
As shown in Figure 1, the off-premises station of air conditioner of the present invention, in off-premises station framework 2 folding and unfolding have compressor 3, heat exchanger 4, with the blower fan 5 and the controller 1 of these heat exchanger 4 relative configurations.Described controller 1 is arranged on the inner upper end of framework 2, and as shown in Figure 2, folding and unfolding has is equipped with the circuit board 6 that is used for compressor 3, blower fan 5 etc. is driven the electrical equipment 9 of control.
Fig. 3, Fig. 4 and Fig. 5 are stereogram, vertical view and the exploded views of described controller 1.As Fig. 3, Fig. 4 and shown in Figure 5, controller 1 has the supporting mass 7 of frame shape, and circuit board 6 is surrounded by this supporting mass 7 and be supported.This supporting mass 7 is formed from a resin, and is integrally formed into to be used for hooking sheet that off-premises station framework 2 is installed on lateral surface.In addition, on medial surface, be formed for circuit board 6 is blocked the card claw stop that is fixed on assigned position.In addition, the panel 8 of the sheet metal system of covering shape is housed on above the supporting mass 7 at this, hermetically covering board above.
Be contained on the described circuit board 6 on the above-mentioned supporting mass 7, the electrical equipment 9 that is used for compressor, blower fan etc. is driven control is installed.That is, because of a side portion caloric value of the length direction of circuit board 6 is big, so power transistor (powertransistor) 9a that is provided with radiating fin (radiator fin) 9a1 is installed on circuit board 6.The splicing ear 9c1 of electrolytic capacitor 9b and lead 9c is installed in addition, below circuit board 6.
On below this supporting mass 7, be provided with the base plate 10 of face of a described side of covering board 6.
This base plate 10 is made by sheet metal, has the interarea portion 10a parallel with the openend of supporting mass 7 and 2 side surface part 10b, 10c, and the cross section is the コ font.The described interarea 10a of portion for example is trapezoidal or triangle.
This base plate 10 was installed on described supporting mass 7 following, formed the zone that described electrolytic capacitor 9b is housed on covering below described circuit board 6 described and vacated the shape in the zone that described conductor terminal 9c1 is housed.
As shown in Figures 1 and 2, the zone that described conductor terminal 9c1 is housed is positioned near for example close right flank 2a in the side of off-premises station framework 2, and the zone that described electrolytic capacitor 9b is housed is positioned at the central authorities of close framework 2.
Here, with reference to Fig. 6 the manufacture method of base plate 10 is described.Base plate 10 is by drawing (stamping).For example, utilize point symmetry ground to form the stamping die (stamping die) of 2 die-cut moulds, once determine 2 flat plate that become base plate 10, they are bent to コ font (horseshoeshape) respectively, make base plate 10 from the sheet metal upper punch.
As mentioned above, the off-premises station of the air conditioner of this example, the 10a of interarea portion of base plate 10 is formed by trapezoidal or leg-of-mutton base plate, but so two base plates of the stamping-out in point symmetry ground, can suppress material unaccounted-for (MUF), and, by the zone of in the empty open circuit plate conductor terminal being housed, no longer need long lead.In addition, lead directly can be connected with conductor terminal.And electrolytic capacitor is covered by base plate, so just in case the big electrolytic capacitor of caloric value catches fire, also can be shielded by base plate, can prevent spreading of fire.In addition, the zone that conductor terminal is housed in the circuit board is positioned at the side of close off-premises station framework, so frequency converter unit (inverter unit) can easily be electrically connected with circuit board.
