Directly or indirectly it is emitted into the outside of annular casing 10.
It should be noted that the top half of arc heat exchanger 20 and the division surface of lower half portion are by annular casing 10
Geometric center and horizontally extending plane.Mean that it leans on near-ring on the inside of a certain component (such as arc heat exchanger 20)
The side of 10 geometric center of shape casing correspondingly means it far from annular on the outside of a certain component (such as arc heat exchanger 20)
The side of 10 geometric center of casing.
Specifically, in some embodiments, arc heat exchanger 20 is circular ring shape arc heat exchanger.Therefore, upper accepting water disk 81
The semicircular arc that is substantially protruding upward out of contour line, the contour line of lower accepting water disk 82 is substantially in the semicircular arc protruded downward.
The condensed water that 20 top half of arc heat exchanger generates as a result, drops under its own gravity positioned at arc
On the upper accepting water disk 81 of 20 inside of heat exchanger, the condensed water that 20 lower half portion of arc heat exchanger generates is under its own gravity
It drops on the lower accepting water disk 82 in 20 outside of arc heat exchanger, the condensed water collected on upper accepting water disk 81 passes through aqueduct 83
It is guided to lower accepting water disk 82, to which annular casing 10 be discharged, avoids the condensing drip of 20 top half of arc heat exchanger generation
It drops down onto its lower half portion or other component or is trapped in the bottom of annular casing 10 and brings security risk.
In some embodiments of the utility model, condensed water collecting device 80 further includes drainpipe 84, is connect under connection
The exterior space of water pond 82 and annular casing 10, outside the condensed water elimination on lower accepting water disk 82 to annular casing 10.

142 and 143 three parts of back casing, and by location layout between front casing body 141, preceding inner housing 142 and back casing 143 and
Connection relation limits round wind outlet 120 and the annular for containing arc heat exchanger 20 and air flow drive device 30 is held
Space is filled, structure and assembly are all very simple, simplify infrastructure cost and cost of labor.
Specifically, the forward edge of preceding inner housing 142 and front casing body 141 can be rounded, and preceding inner housing 142
The center of circle of circle where forward edge can be overlapped with the center of circle of circle where the forward edge of front casing body 141, so that annular goes out
The width all same of each section in air port 120 radially.Before the radius of circle is less than where the forward edge of preceding inner housing 142
The radius of circle where the forward edge of outer housing 141.
In some embodiments of the utility model, the center of annular casing 10 defines front and back open central collar aperture
130, to form negative pressure in central collar aperture 130 when air flow drive device 30 drives and blows, so that indoor without changing
The natural wind of heat through central collar aperture 130 from back to front jet stream and go out and with the gas after the heat exchange sent out through round wind outlet 120
Stream mixing.That is, the center collar aperture 130 among annular casing 10 runs through annular casing 10, and center along the longitudinal direction
Any part can not be placed in collar aperture 130.Under the driving of air flow drive device 30, air-flow after heat exchange is from round wind outlet
120 send out, at this point, can all form negative pressure, 1 rear of air conditioner indoor unit in the outer periphery of round wind outlet 120 and central collar aperture 130
Natural wind gone out by this negative pressuren zone jet stream from back to front of central collar aperture 130, and with sent out through round wind outlet 120
Air-flow mixing after heat exchange.When mixed airflow blows to human body, can achieve the effect that it is cool without cold, warm without heat, improve
The mildness and comfort that air conditioner indoor unit 1 is blown.
As it can be seen that the opening of 130 rear side of central collar aperture forms non-heat exchange wind (i.e. natural wind) import, central collar aperture 130
The opening of front side forms non-heat exchange wind outlet, and round wind outlet 120 is looped around around non-heat exchange wind outlet, in order to
Air-flow after the heat exchange sent out through round wind outlet 120 is equably mixed with the natural wind sent out through the outlet of non-heat exchange wind, into
One step improves the comfortable sexual experience of user.
In some embodiments of the utility model, preceding inner housing 142 extends from the front to the back along the first curve 150.Figure 10
It is the schematic diagram according to first curve of the utility model one embodiment.First curve 150 includes from the front to the back
The first section 151 and the second section 152 for setting gradually and being glossily connected, the first section 151 and the second section 152 are along Figure 10
In dotted line separate.First section 151 is circle arc curve, and the center of circle of circle is in the first section 151 where the first section 151
Outside.It that is to say, the first section 151 is the circle arc curve of the inside protrusion of inner housing 142 forward, on the one hand, Neng Gouzeng
The size in space is contained in big toroidal shell 10, consequently facilitating installation arc heat exchanger 20 and air flow drive device 30, another party
Face also may make the flaring from the front to the back of central collar aperture 130, the i.e. edge of center collar aperture 130 to cut perpendicular to plane in the front-back direction
Area of section gradually increase from the front to the back sent out in diffusion type after central collar aperture 130 so that air-flow flows through, to promote
Mixing between the non-heat exchange air-flow sent out through central collar aperture 130 and the heat exchange air-flow sent out through round wind outlet 120, improves
Mixed effect, to further expand blowing range.
Further, the second section 152 can be straight line；Second section 152 or circle arc curve, the second section
The center of circle of circle where 152 is in the inside of the second section 152, i.e. the second section 152 is that the external of inner housing 142 forward is protruded
Circle arc curve.Further, the length that the second section 152 extends is much smaller than the length that the first section 151 extends.
In some embodiments of the utility model, front casing body 141 extends from the front to the back along the second curve 160.Figure 11
It is the schematic diagram according to second curve of the utility model one embodiment.Second curve 160 includes from the front to the back
The third section 161 and the 4th section 162 for setting gradually and being glossily connected, third section 161 and the 4th section 162 are along Figure 11
In dotted line separate.Third section 161 is circle arc curve, and the center of circle of circle is in third section 161 where third section 161
Inside.It that is to say, third section 161 is the external circle arc curve protruded of outer housing 141 forward, thus with preceding inner housing
142 the first section 151 matches, and further increases the size that space is contained in toroidal shell 10, and also improve annular
The good appearance effect of shell 10.
Further, the 4th section 162 can be straight line；4th section 162 or circle arc curve, the 4th section
The center of circle of circle where 162 is in the outside of the 4th section 162, i.e. the 4th section 162 is the inside protrusion of outer housing 142 forward
Circle arc curve.Further, the length that the 4th section 162 extends is much smaller than the length that third section 161 extends.As a result,
4th section 162 cooperatively can form one with the second section 152 of preceding inner housing 142 in the inside of round wind outlet 120
The necking part of sectional area rapid drop, in order to which that improves round wind outlet 120 goes out wind velocity.
In some embodiments of the utility model, air flow drive device 30 is the envelope of the circumferentially extending along annular casing 10
The annular ion wind generation apparatus closed.Annular ion wind generation apparatus is for promoting indoor air through circular air inlet grid 110
Into in annular casing 10, and flowed towards round wind outlet 120 after the heat exchange of arc heat exchanger 20.Specifically, under high pressure,
