Below in conjunction with a description of drawings example of the present invention.
Fig. 1 represents to form the outward appearance of the indoor unit of air conditioner.This air conditioner is divided into indoor unit and not shown outdoor unit, and by refrigerant tubing the two is communicated with.Above-mentioned indoor unit is fixed on the wall top of air-conditioned room, and above-mentioned outdoor unit then is installed in outdoor.
Covered by grizzly bar 3 as the unit main body 1 of the indoor unit of air conditioner main body is whole, its back side one side then is made of the front panel 2 of comprehensive opening and the back plate 4 that embeds in the backside openings portion of this front panel 2.
Leading flank bottom at above-mentioned front panel 2 is provided with indicator lamp 5, and the bottom offers blowing mouth 7 again, and this blowing mouth 7 is provided with the screen of using as wind guiding member 6.Specifically as shown in Figure 2, the left and right sides portion of the leading flank of above-mentioned front panel 2 is sweeping plate-like portion 2a in cross section and 2a.Opening between these plate-like portions 2a, 2b, and be provided with the pane portion 8 of rectangle at this peristome 2c.
The air cleaner 9 that is supported by pane portion 8 is installed freely in this peristome 2c mounting or dismounting.The pane portion 8 of said units main body 1 is together covered by above-mentioned air-breathing grizzly bar 3 together with plate- like portion 2a, 2a and this air cleaner 9 of its both sides.The top of plate 2 also has top air entry 10 at certain intervals in front in addition.
Plate 4 cross sections, above-mentioned back roughly are the L font, are installed on the plate 4 of back to indoor heat converter 11 and indoor blower 12 subtends, in the side of indoor blower 12 electric parts case 13 are housed simultaneously.
The side of above-mentioned indoor heat converter 11 is inverted v-shaped, is made of front side heat exchanger 11A that is positioned at front one side and the rear side heat exchanger 11B that is positioned at the back side one side.On rear side heat exchanger 11B, also be provided with not shown secondary unit portion along its upper side.
The side of front side heat exchanger 11A is circular-arc, and the side of rear side heat exchanger 11B and secondary unit is the vertical bar shape.And the top of front side heat exchanger 11A is to back side lopsidedness.
Each heat exchanger 11A, 11B are by the multi-disc fin F that is arranged side by side across minim gap and run through these fins F and heat exchanging pipe P that the shape ground that crawls is communicated with constitutes.It is so-called finned tube.
As shown in Figure 3, both side ends (side end only is shown among the figure) at the fin F that constitutes each heat exchanger 11A and 11B, be provided with the cross section and be コ font and the heat exchanger end plate 14 consistent with the side view of each heat exchanger, above-mentioned heat-exchanger pipeline P runs through these heat exchanger end plates 14.
Again as shown in Figure 2, drain pan 15 before the bottom of the front side heat exchanger 11A that constitutes indoor heat converter 11 is provided with is provided with back drain pan 16 in the bottom of rear side heat exchanger 11B.These forward and backward drain pans 15 and 16 all are configured as one with above-mentioned back plate 4.
Between above-mentioned front side heat exchanger 11A and rear side heat exchanger 11B, be provided with above-mentioned indoor blower 12.In other words, relative indoor blower 12, front side heat exchanger 11A and rear side heat exchanger 11B are located at the top, and these heat exchangers generally cover the top just like umbrella.
Each supporting mass 20 all has certain thickness, and inner is provided with not shown bearing part, the fulcrum 17a that protrudes from the both side ends of above-mentioned circulation fan 17 is carried out pivot prop up.Each supporting mass 20 structure is identical, and Fig. 4 only illustrates one of them, and another supporting mass 20 is with shown in this Fig identical, the Therefore, omited explanation.
In inner face one side of these supporting masses 20, promptly by a side of circulation fan 17, be provided with semicircular dewfall along bottom one side in circulation fan 17 axle center and accept body 21.
This dewfall is accepted body 21 by protruding the concave part 22 be arranged on supporting mass 20 side walls integratedly and constituting along the lateral edges setting of this concave part 22 and with dykes and dams portion 23 that supporting mass 20 side walls are stretched out abreast.
So just on supporting mass 20, form dewfall and accept body 21, and form semicircular groove along inner face one side lower part of supporting mass 20.
In addition, the dykes and dams portion 23 that the both side ends of above-mentioned circulation fan 17 is accepted body 21 by dewfall extends to the subtend position of concave part 22, and its circulation fan end plate 17b is positioned at concave part 22.
In case to the instruction that the indoor unit of the air conditioner of said structure sends the beginning operation of air conditioner, just form the kind of refrigeration cycle running to indoor heat converter 11, indoor blower 12 is driven simultaneously.
That is, circulation fan 17 rotation, the air in the air-conditioned room through the front suction gas port of front panel 2, be peristome 2c and top air entry 10 and be inhaled in the unit main body 1.
This air is introduced into rear side heat exchanger 11B after by front side heat exchanger 11A and secondary unit, just forms heat exchange when by these interchangers.If cooling operation, draw from each heat exchanger 11A, 11B after just changing cold air into, and be drawn towards blowing mouth 7 by indoor blower 12, in air-conditioned room, dry the performance refrigeration again from this blowing mouth 7.
In addition, when carrying out cooling operation, the cold air of drawing from indoor heat converter 11 is introduced to blowing mouth 7 through indoor blower 12, and position betwixt just is cooled to below the dew point.Therefore, in this case, moisture contained in the cold air will condense into dew.
But, owing to circulation fan 17 rotates, so dew can be not attached to it.18 of fan motors owing to drive with to a certain degree heating, simultaneously not with the position of indoor heat converter 11 subtends on, do not pass through because of there being cold air, so can not generate dew.
The result is that the cold air of drawing from indoor heat converter 11 just contacts with supporting mass 20 and conducting, and generates dew at the position with its cooling.More particularly, supporting mass 20 has certain thickness, have only inner face one side of this supporting mass 20 to contact with cold air and generate dew, and outside one side is difficult for generating dew because of not contacting with cold air.
As time goes on can be cumulative at the dew that supporting mass 20 inner faces one adnation becomes, can flow down along this inner surface finally.Accumulate near will flowing to blowing mouth 7 like this, and can splash in air-conditioned room or drip along with the cold air that blows out from this blowing mouth 7, the present invention accepts body 21 with the dewfall that is located at supporting mass 20 inner faces one side to accept dew.
That is, dew is introduced to dewfall and accepts in the body 21, and accumulates herein.Since formed groove shape cross section with the side walls of supporting mass 20 and concave part 22 and dykes and dams portion 23, the dew of q.s can be accumulated, and can not overflow to the outside.
In addition, even in stopping the process of cooling operation, after generating dew on the circulation fan end plate 17b, flow down, because this circulation fan end plate 17b is positioned at the concave part 22 that dewfall is accepted body 21, so the dew that flows down is all caught by concave part 22 and can not overflowed to the outside.
Thereby, can avoid dew in air-conditioned room, to splash or drip from blowing mouth 7, can guarantee comfortable air-conditioning state.Because this dewfall is accepted body 21 and is configured as one with supporting mass 20,, can not increase the burden when being shaped so cost is not high yet.
But, above-mentioned example is in each supporting mass 20 inboard of circulation fan 17 both side ends dewfall to be set respectively to accept body 21, certainly be not limited to this structure, above-mentioned dewfall is accepted body 21 also can not be located at supporting mass 20 inner faces by fan motor 18 1 sides, and just is configured as one with the side by the supporting mass 20 of fan motor 18 1 sides not.
That is, as previously mentioned, even fan motor 18 also can generate heat, can directly not generate dew when cooling operation, its heat passes to supporting mass 20 by fan motor 18 1 sides by rotating shaft.Thereby, generating dew by just being difficult on the supporting mass 20 of fan motor 18 1 sides, to accept body 21 influences also little even do not establish dewfall.
In addition, also can adopt structure shown in Figure 5.This structure is to establish opening 25 at the end face that dewfall is accepted body 21, and the dew of the dykes and dams portion 23 of savings between concave part 22 and supporting mass 20 side wall surfaces is flowed down from above-mentioned peristome 25.
The lower portion of this peristome 25 be provided with above-mentioned before drain pan 15, all accepted from whole dews that peristome flows down by preceding drain pan 15.Dew can not be drawn towards blowing mouth 7 at all, thereby as previously mentioned, can guarantee comfortable air-conditioning state.
As mentioned above, adopt air conditioner of the present invention. Even the supporting mass at the supporting pressure fan has dew Generate and flow down, but also Antidewing water splashes to the outside or drips from blowing mouth, can obtain best air-conditioning shape Attitude is compared with the method for traditional solution dew simultaneously, and the present invention can save man-hour, material and cost.
