BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described with reference to FIGS. First, FIG. 5 and FIG.
The configuration of one embodiment of the present invention will be described. Reference numeral 1 denotes an indoor heat exchanger, which constitutes a refrigeration cycle together with an outdoor heat exchanger 2 and a compressor 3.

Reference numeral 4 denotes a blower motor, and the indoor blower fan 5 and the outdoor blower fan 6 are attached to both shafts of the blower motor 4 to form a blower.
The outdoor blower fan 6 is provided with 7 outer peripheral rings.

The indoor blower fan 5 and the outdoor blower fan 6 are rotated by the rotation of the blower motor 4, and are condensed by the indoor heat exchanger 1 and the indoor blower fan 5. The condensed water guided to the outdoor side is splashed up by the outer peripheral ring 7 of the outdoor blower fan 6 and sprayed onto the outdoor heat exchanger 2. At this time, the ring cover 8 prevents the splashed condensed water from splashing to the outside so that the condensed water hits the outdoor heat exchanger 2 like never before.

The ring cover 8 is a circular member having multi-blade ribs 8a and multi-blade ribs 8b as shown in FIGS. 1 to 4 and 7, and having holes between the multi-blade ribs.

The multi-blade rib has an angle with respect to the center of the circle. By setting the arrangement angle of the multi-blade rib at about 10 degrees to about 90 degrees with respect to the center line of the circular member,
It is possible to prevent splashing of condensed water to the outside. In the present invention, the arrangement angle of the multi-blade rib is about 60 degrees with respect to the center line of the circular member, and when viewed from the center of the ring cover 8,
The ribs overlap each other to prevent the condensed water from splashing outside.

Further, since the multi-blade ribs have an angle with respect to the center of the circular shape, not only the splash of condensed water to the outside is prevented, but also the multi-blade ribs generated by the splashed condensed water The collision noise can be reduced and lowered.

The multiblade ribs are arranged at unequal intervals. This is because there is a large air gap between the multi-blade ribs in the direction of increasing ventilation, and the holes between the multi-blade ribs are large, so there is less ventilation resistance and more air is taken in. This is the effect of the ring cover 8 according to the present invention, such that the arrangement interval of the multiblade ribs in the direction is made small and the holes between the multiblade ribs are made small so that condensed water is prevented from splashing to the outside. Improve performance Splash performance improves air conditioner with more efficient blower system.

Further, by manufacturing the ring cover 8 with a porous material or a material capable of absorbing collision noise, it is possible to provide an air conditioner with less collision noise for water treatment.

In addition, the height of the multi-blade rib is determined by the blowing motor 4
By increasing the width of the outer peripheral ring 7 provided on the outdoor fan 6 attached to the shaft from about 1 to about 10 times, as shown in, the splash performance for enhancing the heat exchange performance is improved. The air conditioner has a more efficient blower system with less collision noise for water treatment.

Next, 9 is an outdoor heat exchanger cover,
An air blowing path of the outdoor air blowing fan 6 is configured. Reference numeral 10 denotes an outdoor heat exchanger lid, which, like the outdoor heat exchanger cover 9, constitutes a ventilation path of the outdoor ventilation fan 6.

Next, 11 is a drain receiver, which collects the condensed water condensed by the indoor heat exchanger 1 and the indoor blower fan 5 which form a part of the refrigeration cycle, and is still outdoor. Lead to.

The members 1 to 11 are formed on the base 12, and the condensed water guided by the drain receiver 11 is accumulated outside the base 12.

[0024]

The ring cover of the present invention is a circular member having holes between the multiblade ribs, the multiblade ribs have an angle with respect to the center of the circle, and They are arranged at equal intervals, which increases the arrangement interval of the multiblade ribs in the direction of increasing ventilation to improve heat exchange performance.

Further, the multiblade ribs are arranged at a small interval in the direction in which water splash may occur, and the condensed water condensed by the indoor heat exchanger and the indoor blower fan is
Collected by the drain receiver, accumulated in the base, jumped up by the outer peripheral ring of the outdoor air blower fan that is rotated by the air blower motor, and blown to the outdoor heat exchanger, eliminating the splash of condensed water to the outside, The ring cover according to the present invention is extremely effective in allowing condensed water to reach the outdoor heat exchanger like never before and improving the splash performance for enhancing the heat exchange performance. As a result, the air conditioner has a more efficient blower system, and the ring cover is made of a porous material or a material capable of absorbing the collision noise, so that the collision noise against water treatment is reduced.
