(about the modification of the shape of electric appliance unit)
Though in above-mentioned air conditioner, be housed in electric appliance unit 14 in the casing for electric appliances 20 and 21 coverings of electrical appliance lid, use it as single unit and constitute column (Figure 18), make and make and dispose easily, seeking cost reduces, and raising reliability, but also can be as shown in Figure 16 constitutes electric appliance unit 14 as a plurality of unit 14a, 14b, the 14c that are set up in parallel on straight line substantially.Specifically, constitute electric appliance unit 14, these a plurality of printed boards are contained on the same substrate, and couple together on electric mutually with a plurality of printed boards.And, being easy to viewpoint from densification, disposal in the occasion that constitutes electric appliance unit 14 as mentioned above, electric appliance unit 14 preferably totally forms column substantially as it.In addition, electric appliance unit 14 also can be as shown in Figure 17, and no matter each unit 14a, 14b, 14c are with respect to longitudinally, still disposes mutually with respect to the direction (airflow direction) of intersecting with longitudinally with staggering and constitute.By constituting like this, can improve the selection free degree of its allocation position, with the corresponding possibility that suitably is configured as of machine.
And constitute the occasion of electric appliance unit 14 being divided into a plurality of unit as mentioned above, electric appliance unit 14 is configured to each electric appliance unit 14 becomes the longitudinally total length LA of indoor set housing 1 along the aggregate value (a+b+c) of the size of the longitudinally of indoor set housing 1 the length more than at least 1/3, or electric appliance unit 14 is configured to each electric appliance unit 14 becomes the length more than at least 1/3 of the longitudinally total length LB of blow-off outlet 11 along the aggregate value (a+b+c) of the size of the longitudinally of indoor set blow-off outlet 11, perhaps electric appliance unit 14 is configured to each electric appliance unit 14 becomes indoor set housing 1 or blow-off outlet 11 along the aggregate value (a+b+c) of the axial dimension of indoor machine fan 9 longitudinally total length LA, the length more than at least 1/3 of LB is just passable.That is to say the occasion that constitutes by a plurality of unit at electric appliance unit 14, stipulate its length, can obtain the densification of indoor set, the such advantage of raising of heat pump performance whereby according to the aggregate value (a+b+c) of each size of each electric appliance unit 14.In this occasion also be, the longer the better for the aggregate value of each size of electric appliance unit 14 (a+b+c), should be taken as longitudinally size LA, more than at least 1/2 of LB of indoor set housing 1 or blow-off outlet 11, is more preferably to be taken as more than 2/3.
In addition preferably with the short transverse (above-below direction) of the longitudinally quadrature of indoor set housing 1 on, as shown in Figure 19, the short transverse size t of above-mentioned electric appliance unit 14 is below 1/3 of short transverse total length T of above-mentioned indoor set housing 1.If constitute like this, then can further reduce flowing resistance, the free degree that improves the configuration of electric appliance unit 14 becomes possibility.
(about the modification of the allocation position of electric appliance unit)
Though in the above-described embodiments, electric appliance unit 14 is configured in the position on blow-off outlet 11 tops, and on the position of drain pan 13 front face side, the allocation position of electric appliance unit 14 can followingly change.Moreover also be to use same as before in following modification about the above-mentioned explanation of the size and dimension of electric appliance unit 14.At first in Figure 20, electric appliance unit 14 is configured in the air flue 33 between front side heat exchanger 2 and the front panel 7.In this occasion, because the basal area of electric appliance unit 14 and above-mentionedly similarly diminish, so can suppress the increase of flowing resistance.And when the two operation of changes in temperature, cool off electric appliance unit 14 by ventilating air and become possibility, the reliability of raising electrical equipment becomes possibility.In addition because electric appliance unit 14 is an elongated shape, the local configuration of impartial cloth along about the longitudinally, if, therefore can suppress the generation of problems such as rotor dewfall so, also do not become the unbalanced flowing resistance in the left and right sides even supposition becomes the flowing resistance of suction side.
In Figure 21 and Figure 22, similarly front side heat exchanger 2 and rear side heat exchanger 3 are combined into inverted v-shaped and constitute indoor heat converter 4 in the indoor set housing 1 with above-mentioned, and electric appliance unit 14 is configured to make 2,3 combinations of two heat exchangers at the crossover location of front side heat exchanger 2 and rear side heat exchanger 3.In the occasion of Figure 21, the long limit in the section of electric appliance unit 14 is configured to along the state of air stream, the occasion of this external Figure 22, and the minor face in the section of electric appliance unit 14 is configured to along the state of air stream.Though in this modification, become electric appliance unit 14 and realize the function of the cross part of sealing front side heat exchanger 2 and rear side heat exchanger 3, but by on electric appliance unit 14, going back other functions of dual-purpose like this, can omit the use of special-purpose encapsulant, can reduce manufacturing cost.If two kinds of functions of dual-purpose then can correspondingly reduce requisite space in addition, therefore also can seek the raising of the densification and the heat pump performance of indoor set in this.Moreover in these occasions also be, cooling off electric appliance unit 14 by ventilating air when the two operation of changes in temperature becomes possibility, and the reliability of raising electrical equipment becomes possibility.Moreover electric appliance unit 14 is being configured to make the occasion of two heat exchangers 2,3 in the crossover location combination of two heat exchangers 2,3, sealing special-purpose member ground also can be set in addition implement, also can obtain the densification of indoor set, the such advantage of raising of heat pump performance this moment.
In Figure 23, electric appliance unit 14 is configured in the rear side more of the rear side heat exchanger 3 of indoor set housing 1.Owing in indoor set housing 1, electric appliance unit 14 is configured in the zone of the rear side that is arranged in the indoor set that becomes the space that remains in a standstill completely like this, so can effectively utilize the space in the indoor set housing 1 more, the result further makes the indoor set densification, further improve heat pump performance becomes possibility.
In Figure 24, electric appliance unit 14 is configured in the dorsal area of the scroll portion that constitutes the back wall that blows out path.Owing in indoor set housing 1, electric appliance unit 14 is configured in the dorsal area of the scroll portion 10 of the rear side that is arranged in the indoor set that becomes the space that remains in a standstill completely like this, so can effectively utilize the space in the indoor set housing 1 more, the result further makes the indoor set densification, further improve heat pump performance becomes possibility.This external this occasion, though electric appliance unit 14 is configured in outside the air flow path in the indoor set housing 1, its result can suppress because of electric appliance unit 14 directly increases flowing resistances, therefore suppresses to reduce because of the setting air conditioner performance of electric appliance unit 14.
(about other modifications of the size of electric appliance unit, shape, allocation position)
Though in the various embodiments described above, about the size of the longitudinally of electric appliance unit 14 by stipulating with the related of longitudinally size of indoor set housing 1 or blow-off outlet 11, it is above-mentioned that but the size of the longitudinally of electric appliance unit 14 is not limited to, and can change by working hard on its configuration.For example, if constitute the electric appliance unit 14 that the remaining space that extends along longitudinally that utilizes in the indoor set housing 1 disposes the dimensional ratios that has improved longitudinally, then electric appliance unit 14 being configured in from all spaces of seeing with the longitudinally cross section orthogonal of indoor set housing 1 becomes possibility.That is to say does not need as prior art the special space used at the sidepiece configuration electrical equipment of indoor set housing 1.Therefore the longitudinally size of indoor set can be reduced, the indoor set densification can be made.Therefore if improving heat pump performance more than prior art becomes possibility in addition this point conversely speaking, then in the indoor set of same size, can increase the configuration space of heat exchanger 4 or fan 9.Moreover so-called " improving the dimensional ratios of longitudinally " size of being meant longitudinally is greater than in the size of the both direction of quadrature with it any one, and the magnitude relationship of its ratio is out of question.But preferably the longitudinally dimensional ratios of electric appliance unit 14 is added the longitudinally dimensional ratios of great achievement greater than indoor set housing 1.
