As shown in Figure 4 (b), by forming outside side wall face in the outside of the side wall surface keeping the electrical install substrate holder 1g of electrical install substrate 1a, in electrical install substrate holder 1g, sidewall sections becomes dual structure.Between the dual structure of electrical install substrate holder 1g, basement substrate 1f from below.
In addition, the cover 1h forming power supply box 1b has the flange part chimeric with electrical install substrate holder 1g.Flange part is the dual structure of medial flange portion 1k and outboard flanges portion 1m.Constrained shape (Trappedshape is become with the small gap formed by the side wall surface of flange part and electrical install substrate holder 1g, tired shape) mode, flange part is with chimeric with electrical install substrate holder 1g from the mode of outer side covers electrical install substrate holder 1g.
By forming as described above, in the electrical installation unit 1 that can prevent from foreign matter from invading receiving electrical install substrate 1a.
Being that metal is made by making basal substrate 1f, not burning reply (non-ignitibility structure) can be carried out.In addition, peucinous electrical install substrate holder 1g receives electrical install substrate 1a, can form insulation structure thus.Even if main body 2 falls when carrying, the electrical install substrate 1a of electrical installation unit 1 inside also can be protected injury-free.
In addition, as shown in Fig. 2 and Fig. 4 (a) and (b), the cross section of the cover of power supply box 1b is formed as trapezoidal shape.Thereby, it is possible to make the exterior region height reduction of top panel 80.In addition, the size that the front of forward face panel 4 can be suppressed to stretch out, reduces the depth size from wall, therefore, it is possible to realize the densification of electrical installation unit 1.
According to the structure of above-mentioned electrical installation unit 1, the width in the wind loop in main body 2 and the width of blow-off outlet 10 can be made to become large.
As shown in Figure 2, electrical installation unit 1 is laterally configured at and the position of the inclined plane 6a of heat exchanger 6 at a distance of the distance D1 of more than 20mm longlyer.In addition, distance D1 is the distance recorded in the vertical direction to electrical installation unit 1 from the inclined plane 6a of heat exchanger 6, makes it be beeline from heat exchanger 6 to electrical installation unit 1.In addition, the short side direction width of the depth wide D2(basal substrate 1f of the electrical installation unit 1 in present embodiment) be 100mm.That is, relative to the wide D2 of the depth of electrical installation unit 1, be 20% with the distance D1 of heat exchanger 6.At such configuration electrical installation unit 1 and when indoor set is operated, the wind of the perimeter of electrical installation unit 1 state (wind speed profile) as shown in Figure 6.
Fig. 6 is the figure of the flowing representing wind with arrow, represents the size (wind speed) of wind with the length of arrow, represents the direction (wind direction) of wind with the angle of arrow.As shown in Figure 6, at the back side (between electrical installation unit 1 and heat exchanger 6) of electrical installation unit 1, also integrally flow through wind throughout the depth of electrical installation unit 1 is wide.That is, by the wide D2 of depth that is electrical installation unit 1 with electrical installation unit 1 with the distance D1 of heat exchanger 6 more than 20% mode configure electrical installation unit 1, make the distinguished and admirable whole back side crossing electrical installation unit 1.Thereby, it is possible to effectively prevent the condensation of electrical installation unit 1.In addition, by arranging distance D1 to guarantee space between electrical installation unit 1 and heat exchanger 6, the installation that filter 16 can be guaranteed, the operability unloaded.
As shown in Figure 2, configuring by making electrical installation unit 1 leave the distance D3 of more than 50mm from the lower end in the suction opening portion of filter 16 to upside, the air quantity of the upper end by stabilizing member 32 can be guaranteed.Thereby, it is possible to minimizing suction resistance, prevent the generation of abnormal sound.
By the position (by being configured at than the position by the height and position of rotating shaft 8c and the more top side of center 8a) making electrical installation unit 1 be configured at the more top side of rotating shaft 8c than fan 8, the harmful effect that the wind performance that can reduce electrical installation unit 1 pair of fan 8 is to greatest extent brought.In addition, rotating shaft 8c and center 8a is the center of the short transverse of fan 8 in wind loop.
At this, the general wind speed profile of air conditioner as shown in Figure 7.As shown in Figure 7, the wind speed on the front surface top of heat exchanger 6 is little compared with other parts, is therefore stable region.On the other hand, near fan 8, near blow-off outlet 10, be equivalent to the part of the rear side of indoor set 2 and the front surface bottom of indoor set 2, wind speed is larger.Electrical installation unit 1 is set by the bight 81 on the front surface top at indoor set, makes electrical installation unit 1 be configured at region stable in the wind speed profile of fan 8, the harmful effect that the wind performance that can reduce electrical installation unit 1 pair of fan 8 is brought.
In addition, by the position making electrical installation unit 1 be configured at upper end (top, periphery 8b) the more top side than the fan 8 in wind loop in bight 81, electrical installation unit 1 is made to be configured at the region that in the wind speed profile of fan 8, wind speed is slow especially, the harmful effect that the wind performance that can reduce electrical installation unit 1 pair of fan 8 is further brought.In addition, the reduction of the heat exchanger effectiveness of front side heat exchanger 6b can be prevented thus.
Fan 8, for fan 8 is rotated fan driving motor (not shown) in, due to the spinning movement of fan 8, the motion of fan driving motor and produce vibration, this vibration may be passed to other functional parts etc. and resonate.When particularly resonance occurs electrical mounting device etc., there is inner electrical install substrate 1a and to be short-circuited (short), to cause the possibility of misoperation.
Thus, in main body 2, configure electrical installation unit 1 in the bight 81 being in distance fan 8 position farthest, the vibration from fan 8, fan driving motor can be reduced thus.The air conditioner that reliability is high can be provided thus.
By configuring electrical installation unit 1 as mentioned above, preventing of the dysgenic reduction of wind performance and the condensation of electrical installation unit 1 can be realized simultaneously.In addition, as shown in Figure 1, by making the cross section of electrical installation unit 1 not be formed as rectangle, but being formed as lacking the trapezoidal of a part, electrical installation unit 1 can being accommodated in the main body 2 of indoor set compactly.
In addition, as in this embodiment during switch front surface panel 4, the driving center of the actuating arm 42 of front surface panel automatic switch (driving shaft 42a) is made to be configured at the front surface top of electrical installation unit 1, apply flexibly dead space, make the profile lines of indoor set be guaranteed thus, ensure that good design.Now, driving shaft 42a be at least configured in the below of the upper surface of indoor set and be configured at the inner side of the profile lines of the front surface of indoor set.
In addition, in the air conditioner of present embodiment, front surface panel 4 utilizes actuating arm 42 to carry out switch.Thereby, it is possible to make wind all over the whole region of surrounding of electrical installation unit 1, can prevent electrical installation unit 1 from condensing.And then, when front surface panel 4 moves to the front of main body 2, because be formed with front surface opening portion 9a between front surface panel 4 and front side heat exchanger 6b, so can, by the running of fan 8, make front surface panel 4 become guiding piece and the front side heat exchanger 6b that led by air.Thus, even if there is the flowing resistance caused by the configuration of electrical installation unit 1, air also can be directed to the space (being equivalent to the part of distance D1) be arranged between electrical installation unit 1 and front side heat exchanger 6b.The reduction of the heat exchanger effectiveness of heat exchanger 6 can be suppressed thus.
Then, the fixed structure of electrical installation unit 1 is described.
