And, in indoor set 93, go back motor-driven valve 33a, the refrigerant piping 133 that is connected with motor-driven valve 33a, and make the cold-producing medium that flows out motor-driven valve 33a be diverted to the current divider 39 etc. of each heat-transfer pipe of indoor heat converter 4a, all be arranged in the space that difference produced by the effective length of front side heat exchange department 41 and rear side heat exchange department 42.As shown in Figure 5, maintenance for convenience, motor-driven valve 33a is a lateral arrangement.
Moreover, in indoor set 93, surrounded the space of arranging parts such as motor-driven valve 33a with crown cap 50, last lower clapboard 44 and left and right sides dividing plate 45.Crown cap 50 is sheet metal parts of an integral body, the 1st cover plate 51 by covering space SP top, the 2nd cover plate 52 that extends downwards sideling from the front of the front end edge front side heat exchange department 41 of the 1st cover plate 51, with stretch to declivity from the rear end of the 1st cover plate 51, and the 3rd cover plate 53 at covering space SP rear constitutes.This crown cap 50 mainly is provided with for sound insulation.On the other hand, last lower clapboard 44 and left and right sides dividing plate 45 are in order to prevent that the air in the inflow space SP from letting out and the metal plate-like parts that are provided with from fan runner one side.Last lower clapboard 44 is positioned at the top of fan runner 3, space around the fan runner 3 with arranged that the space S P of motor-driven valve 33a etc. separates.Left and right sides dividing plate 45 is vertically extending forward from the end 42b of space S P one side of rear side heat exchange department 42, parts roughly triangular in shape, the end 42b of leg-of-mutton each bar limit and rear side heat exchange department 42, the end of space S P one side of connecting plate 43, and upward the end of lower clapboard 44 vertically connects.
In addition, preceding drip tray 61 and back drip tray 62 are arranged in the below of front side heat exchange department 41 lower ends and the below of rear side heat exchange department 42 lower ends.These two drip trays the 61, the 62nd, with Fig. 2 in the parts that form on the after-poppet of spline structure and drip tray assembly of existing low trestle 12 and drip tray assembly 18, play the effect of accepting the condensed water that drips from indoor heat converter 4a etc.And, in indoor set 93, can be in order to ensure condensed water from above-mentioned lower clapboard 44 and the left and right sides dividing plate 45 gone up round space S P, and drop onto on the fan runner 3 with the cross section of the end 42b of space S P one side of rear side heat exchange department 42, drainage channel 63 below this part, formed.This drainage channel 63 is the alternating share places at last lower clapboard 44 and left and right sides dividing plate 45, metallic plate (is gone up the part of lower clapboard 44, the part of left and right sides dividing plate 45 perhaps is installed in other parts on these dividing plates 44,45) formation of crooked back, the cross section is the parts of bag shaped structure.Therefore, the condensed water that drips down through left and right sides dividing plate 45 from the end 42b of rear side heat exchange department 42, with because of pressure differential from space S P through the gap, cross section from last lower clapboard 44 and left and right sides dividing plate 45, the condensed water that goes out through passing through fan runner 3 effluents, all be imported in the drainage channel 63, flow into then in the drip tray 62 (with reference to Fig. 6).
The feature of＜indoor set 〉
(1)
In indoor set, at first, make the effective length weak point of the effective length ratio front side heat exchange department 41 of rear side heat exchange department 42, and produce the space S P of regulation in the back side of indoor set 93 side.Can produce the refrigerant loop arrangements of components that is called motor-driven valve 33a and current divider 133 of bigger noise in this space S P during then, the change flow of refrigerant.Like this, because can be arranged in the rear side of indoor set 93 to the noise source of motor-driven valve 33a etc.,, can reduce the decibel of the indoor noise that the people heard so judge from the directionality of sound transmission.
(2)
In indoor set 93, not only the refrigerant loop arrangements of components that motor-driven valve 33a etc. is become noise source is in the space S P of indoor set 93 back sides one side, suppressing to leak into the volume of indoor set 93 positive sides, but also with crown cap 43 covering space SP.Thereby, even the high-decibel noise that is produced by 33a such as motor-driven valves can penetrate common shell by resin manufacture, leak into indoor set 93 outsides situation under because the soundproof effect of crown cap 43 has been arranged, just can suppress the outside that this noise leakage arrives indoor set 93.
In addition, preferably use with the sound insulation means that cover the available technology adopting of motor-driven valve 33a with putty or rubber.
(3)
In indoor set 93, because the effective length of the effective length ratio front side heat exchange department 41 of rear side heat exchange department 42 is short, so the length of the fan runner 3 suitable with the effective length of front side heat exchange department 41 is longer than the length of rear side heat exchange department 42.Like this, space S P is located in the top of a part of motor 14 sides of fan runner 3.
In the case, if between space S P and fan runner 3, do not establish any parts, will there be free flow of QI being obstructed to cross in each heat exchange department 41,42 of indoor heat converter 4a any one, but directly flows to the danger of fan runner 3 from space S P.
For this reason, in indoor set 93, between space S P that arranges motor-driven valve 33a etc. and fan runner 3, last lower clapboard 44 and left and right sides dividing plate 45 have been arranged, do not flow through each heat exchange department 41,42 of indoor heat converter 4a so can prevent air, and directly flow to the phenomenon generation of fan runner 3 from space S P.
(4)
In indoor set 93, last lower clapboard 44 has prevented that air from flowing to fan runner 3 downwards from space S P, and left and right sides dividing plate 45 has prevented that air from flowing to fan runner 3 between the end 42b of space S P by front side heat exchange department 41 and rear side heat exchange department 42.And, as shown in Figure 6, because go up the top that the lower end of lower clapboard 44 and left and right sides dividing plate 45 is positioned at drip tray 62, so even water droplet is when the end 42b of rear side heat exchange department 42 etc. flows on the dividing plate 44,45, these water also can flow in the drip tray 62.
In addition, because the difference that is stressed waits influence, flow to dripping of fan runner 3 sides through the gap from the end 42b of the rear side heat exchange department 42 shorter and the alternating share of two dividing plates 44,45, then by drainage channel 63 guiding drip trays 62 than fan runner 3.Therefore, as mentioned above, even be provided with space S P, and surround under the situation of space S P with dividing plate 44,45, dripping can not drop onto on the fan runner 3 yet.
(5)
The indoor set 93 that possesses motor-driven valve 33a is difficult to intactly use on the indoor set of pairing formula air conditioner.But, structurally can replace matching the indoor heat converter of formula used for indoor machine with the heat exchanger 4a of indoor set 93, and between how desk-top and pairing formula air conditioner, realize the generalization of shell.
For example, aspect the generalization of shell, how desk-top indoor set for office usefulness, can be as above-mentioned indoor set 93, the heat exchange department indoor heat converter different with the effective length of rear side heat exchange department in front side is set, and, the heat exchange department indoor heat converter identical with the effective length of rear side heat exchange department in front side can be set then for pairing formula indoor set.
According to the indoor set of claim 1, the effective length of the effective length ratio front side heat exchange department of rear side heat exchange department is short, produces the space of regulation in the back side of indoor set one side.And, can produce bigger noise when changing flow of refrigerant, the refrigerant loop arrangements of components that is called motor-driven valve and current divider is in this space.Therefore, the noise content that leaks into the indoor set front has seldom reduced the sense of discomfort that is in indoor people.
According to the indoor set of claim 2, the motor-driven valve of the indoor set inside that is installed in how desk-top air conditioner usually is arranged in the space of the back side one side of indoor set inside of easy partition noise.Though motor-driven valve can produce bigger noise when regulating refrigerant amount,, can not hear very big noise so be in indoor people because being arranged in noise is not easy to leak in the above-mentioned space of going the indoor set outside.
According to the indoor set of claim 3, in the space of the back side of indoor set inside one side, not only can suppress the refrigerant loop arrangements of components volume of noise leakage, but also cover above-mentioned space with metal parts to the positive side of indoor set.Therefore, even can penetrated usually enclosure leak by resin manufacture by generations such as motor-driven valves to the situation of the high-decibel noise of indoor set outside under, the soundproof effect owing to crown cap can reduce the noise that leaks into the indoor set outside.
According to the indoor set of claim 4, because arranged wind-proof component between the space of installation refrigerant loop parts and the fan runner, so the air that can avoid not flowing through heat exchanger directly flows to the fan runner.
According to the indoor set of claim 5, because the lower end of wind-proof component extends to drip tray always, therefore, drip to water on the wind-proof component from heat exchanger etc., can flow in the drip tray that has had in the prior art.Like this, just can prevent that sealing drops onto on the fan runner from wind-proof component.
