Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an air blowing portion of an air conditioner.

[0002]

2. Description of the Related Art In the air outlet of an air conditioner, since the air outlet is generally long in the left-right direction, a long member that is long in the left-right direction is used. It is required that these are lightweight and have appropriate strength. To be done. Also, these members are
In order to prevent condensation on the air outlet due to the temperature difference from the outside air, a structure with strong heat insulation is required.

As shown in FIG. 2, generally, an air blowing portion 90 of an air conditioner 9 is provided below a heat exchanger 91 and a blower fan 92, and has a drain pan 93 forming the upper side of the air outlet and a lower plate 94 forming the lower side. A vertical blade 95 and a horizontal blade 96 for adjusting the wind direction are arranged between the and. As shown in FIG. 2, the vertical blade 95 is rotatably attached to a blade shaft 951 mounted between the drain pan 93 and the lower plate 94.

Further, as shown in FIG. 3, the horizontal blade 96 is rotatably pivotally attached to shaft holes 962 of support pieces 961 attached to the left and right ends of the drain pan 93 and the lower plate 94. And drain pan 9 which is a resin molded product
3 and the lower plate 94 have heat insulating materials 931 and 941 for preventing dew condensation due to a temperature difference between the outside air and the blown air.
Are attached respectively. Moreover, a concave drain reservoir 932 for accommodating the drain discharged from the heat exchanger 91 is provided above the drain pan 93. Figure 2
In the figure, reference numeral 97 is a front grill and reference numeral 98 is a bottom frame.

[0005]

However, there are the following problems in the above conventional air blowing section. Drain pan 9
3 and the lower plate 94 are required to have a heat insulating property, a light weight, and an appropriate rigidity so as not to be deformed or warped. However, if ribs for reinforcement are provided on the drain pan 93 and the lower plate 94 to enhance rigidity, the heat insulating material 9
There is a problem that it is difficult to attach 31,941 and a problem that the rib portion is warped or sinked during injection molding. In view of the above conventional problems, the present invention is to provide a structure of an air blowout portion of an inexpensive air conditioner that is excellent in heat insulation and strength.

[0006]

The present invention relates to a structure of an air blowout portion of an air conditioner provided below a blower fan, the air blowout portion including a drain pan forming an upper side of the air blowout opening and an air blowout opening. It has a lower plate that forms the lower side, a vertical blade that is disposed between the lower plate and the horizontal blade that adjusts the wind direction to the left and right, and a horizontal blade that adjusts the wind direction to the upper and lower sides. The structure of the air blower of the air conditioner is characterized in that it is integrally molded of resin and has a hollow portion formed in the left and right longitudinal directions inside each of them.

What is most noticeable in the present invention is that the drain pan and the lower plate are integrally molded of synthetic resin, and a hollow portion formed in the longitudinal direction is provided inside each of them. The hollow part above is
For example, it is formed by a gas injection method, a core back method, or the like. The gas injection method is a method of injecting a synthetic resin into a mold and then injecting a gas such as air or nitrogen into the synthetic resin which is still in a molten state to form a hollow portion. As described above, the latter core back method is a method in which the hollow portion is formed by retracting the core while injecting the gas after injecting the synthetic resin.

[0008]

In the air conditioner of the present invention, a hollow portion is provided in the drain pan and the lower plate of the air blowing portion. If a hollow part is provided inside a member made of synthetic resin or the like, the elastic coefficient increases and the strength increases significantly. Further, by providing the hollow portion, the heat insulating property at that portion is significantly improved. By providing the hollow portion as described above, the strength can be secured without providing a reinforcing member such as a rib.

Further, since the heat insulating property is improved, the conventional heat insulating materials 931 and 941 in the air blowing portion are unnecessary,
The number of parts is reduced, and the assembly man-hours are also unnecessary,
Cost reduction. Further, since the hollow portion in the drain pan and the lower plate can be formed simultaneously at the time of injection molding by, for example, the gas injection method, the component cost of the drain pan and the lower plate hardly increases.

Further, there is no problem such as warpage or sink mark associated with injection molding as in the case where ribs are provided. As described above, according to the present invention, it is possible to provide the structure of the air blowout portion of the inexpensive air conditioner having excellent heat insulation and strength.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An air blowing section according to an embodiment of the present invention will be described with reference to FIG. This example is a structural example of the air blowout part 10 of the air conditioner 1 provided below the blower fan 41, as shown in FIG.

The air outlet 10 has a drain pan 12 forming an upper side of the air outlet 11, a lower plate 13 forming a lower side of the air outlet 11, and a wind direction disposed between the both 12, 13 left and right. Adjust vertical blade 14
And a horizontal blade (not shown) for adjusting the wind direction up and down.

The drain pan 12 and the lower plate 13 are
Each of them is integrally molded of synthetic resin, and has hollow portions 161 and 162 formed in the longitudinal direction in the insides of 12 and 13, respectively. What is the above longitudinal direction?
It is the direction that extends in the left-right direction toward the air outlet, that is, the direction along the horizontal blade.

As shown in FIG. 1, a wind collecting plate 122 and a wind draft plate 123 are provided above and below a bottom plate 121 of the drain pan 12, and a drain arm 124 for forming a drain reservoir 17 is provided between the two. Is projected. A hollow portion 161 not filled with resin is provided between the drain arm 124 and the bottom plate 121.

A hollow portion 162 is also formed in the lower plate 13 along the air outlet 11. These hollow portions 161 and 162 are formed during the injection molding of the drain pan 12 and the lower plate 13 by using the gas injection method. Note that Fig. 1
Reference numeral 42 denotes a heat exchanger.

Next, the function and effect of this example will be described. The drain pan 12 and the lower plate 1 of the air blowing part 10 of this example
3 are hollow portions 161 and 16 along the longitudinal direction, respectively.
Two are provided. Therefore, the strength of the drain pan 12 and the lower plate 13 is significantly increased, and it is not necessary to provide a reinforcing member such as a rib.

Further, the presence of the hollow portions 161 and 162 improves the thermal insulation between the facing portions around the hollow portions 161 and 162. Therefore, the conventional heat insulating material (reference numeral 931, 941 in FIG. 3) provided in the air blowing portion is unnecessary, the number of parts is reduced, and the number of assembling steps is also unnecessary.

Further, since the hollow portions 161 and 162 can be formed at the same time when the drain pan 12 and the lower plate 13 are injection-molded, the cost of both members 12 and 13 hardly increases. Therefore, the cost of the entire air blowing unit 10 is significantly reduced. As described above, according to this example, it is possible to provide the structure of the air blowout portion of the inexpensive air conditioner which is excellent in heat insulation and strength.
