[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an air conditioner including a wind direction changing blade at an outlet.
[0002]
[Prior art]
In general, an air conditioner having a wind direction changing blade having a blade louver and a support louver connected to both ends of the blade louver and rotatably supporting the blade louver is known. In this type, as shown in FIG. 6, by fitting the convex portion of the blade louver 16 into the concave portion of the support louver 17, both the louvers 16 and 17 are connected to form the wind direction changing blade 15. Yes.
[0003]
In this type of air conditioner, during the cooling operation, condensation occurs according to the temperature difference between the front surface and the back surface of the wind direction changing blade 15, and when this cooling operation is continued, dew drops from the lower end of the air direction changing blade 15 into the room. There is a problem of doing.
[0004]
For this reason, conventionally, for example, the front and back surfaces of the wind direction changing blade 15 are flocked with an absorbing member to absorb and diffuse the generated condensation, and spontaneously evaporate to prevent the condensation water from dripping into the room or change the wind direction. The blades 15 themselves are made of a water-absorbing ceramic to increase the water absorption capability, thereby preventing the condensation from dropping into the room (for example, refer to Japanese Utility Model Publication No. 4-48438).
[0005]
[Problems to be solved by the invention]
However, in the conventional structure, not only the blade louver 16 but also the support louver 17 has to be implanted in the whole surface, so that it is very difficult to plant the support louver 17 and the manufacturing cost is increased.
[0006]
Then, the objective of this invention is providing the air conditioner which eliminates the subject which the prior art has, and can omit the flocking to a support louver.
[0007]
[Means for Solving the Problems]
The invention according to claim 1 is an air conditioner including a blade louver and a wind direction changing blade having a blade louver and a support louver that is connected to both ends of the blade louver and rotatably supports the blade louver. The lower edge of the blade louver at the connecting portion with the support louver extends below the lower edge of the support louver, and only the blade louver is implanted.
[0008]
According to a second aspect of the present invention, there is provided an air conditioner including a blade louver and a wind direction changing blade having a blade louver and a support louver that is connected to both ends of the blade louver and rotatably supports the blade louver. Both louvers are connected by fitting the end edge portion into the fitting hole of the support louver, and the lower edge of the blade louver in this connecting portion extends to the lower part of the lower edge of the support louver, Only flocked.
[0009]
According to these inventions, since the lower edge of the blade louver extends to the lower part of the lower edge of the support louver, the condensation formed on the entire front and back surfaces of the support louver is caused by the lower edge of the blade louver from the lower edge of the support louver. Since it is absorbed and diffused by the lower edge of the blade louver and spontaneously evaporates there, the support louver does not need to be absorbed, it only needs to be formed of resin, etc. A simple wind direction changing blade can be obtained.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0011]
In FIG. 1, the code | symbol 1 shows the air conditioner called a four-way ceiling cassette type | formula air conditioner. The air conditioner 1 includes a main body 2 and a decorative panel 3 (hereinafter simply referred to as “panel”). The main body 2 is disposed on the ceiling 4 and accommodates a heat exchanger, a blower (not shown) and the like.
[0012]
A panel 3 is disposed below the main body 2 so as to be substantially flush with the ceiling 5, and a suction grill 6 for sucking room air is provided at the center of the panel 3. Air outlets 7a, 7b, 7c, 7d are provided around the suction grill 6, and air direction changing blades 80a, 80b, 80c, 80d capable of freely changing the air direction are attached to these air outlets 7a-7d. . The room air (solid arrow A) sucked in from the suction grill 6 is blown out from each of the outlets 7a to 7d (solid arrow B) after heat exchange in the heat exchanger in the main body 2.
[0013]
FIG. 2 shows the back surface of the panel 3.
[0014]
An opening 10 is provided in the center of the panel 3, and the above-described suction grill 6 (see FIG. 1) is attached to the opening 10. Motors 11a and 11b for driving the wind direction changing blades are arranged at diagonal positions of the panel 3, and wind direction changing blades 80a to 80d are connected to the drive shafts 12 and 13 of the motors 11a and 11b, respectively. . According to this, the wind direction changing blades 80a to 80d are rotated by the motor 11 to change the wind direction.
[0015]
This embodiment is characterized by the configuration of the four wind direction changing blades 80a to 80d. That is, as shown in FIG. 3, each of the wind direction changing blades 80a to 80d includes a blade louver 81a and a support louver 82a connected to both ends of the blade louver 81a. Since each of the wind direction changing blades 80a to 80d has the same structure, the wind direction changing blade 80a will be described as a representative for convenience of explanation.
[0016]
The blade louver 81a is made of aluminum, for example, and a water-absorbing member 83a is planted on the entire front and back surfaces, and two notches 101a and 101b are present at both ends. The notches 101a and 101b allow the blade louver 81a to The end portion is divided into an upper edge end portion 81Xa, a central end portion 81Ya, and a lower edge end portion 81Za.
[0017]
On the other hand, the support louver 82a is made of resin, and the above-described members 83a and the like are not planted on the entire front and back surfaces of the support louver 82a. As shown in FIG. 3, an opening 84a into which the central end 81Ya of the blade louver 81a is inserted is formed at the end of the support louver 82a. Reference numeral 85a is a shaft.
[0018]
According to this embodiment, when both the louvers 81a and 82a are connected by fitting the center end portion 81Ya of the blade louver 81a to the opening 84a of the support louver 82a, as shown in FIG. The lower edge of 81a extends to the lower part of the lower edge of the support louver 82a.
[0019]
Next, the operation will be described.
[0020]
When this air conditioner is performing a cooling operation, as shown in FIG. 5, the cool air guided to the wind direction changing blade 80a is blown out from the air outlet 7a. This cold air is blown out while being in contact with the front and back surfaces of the blade louver 81a and the support louver 82a constituting the wind direction changing blade 80a, but condensation occurs on either surface due to the temperature difference between the air in contact with the front and back surfaces. .
[0021]
The condensed water generated on the surface of the blade louver 81a is absorbed and diffused by the member 83a planted on the entire surface of the blade louver 81a, so that the condensed water is naturally evaporated to prevent the condensed water from dropping into the room. Condensed water generated on the entire front and back surfaces of the support louver 82a flows out from the lower edge of the support louver 82a to the lower edge 81Za of the blade louver 81a, and is absorbed and diffused by the member 83a planted in the blade louver 81a. The In short, even if the support louver 82a is not planted, the condensed water generated there flows out from the lower edge to the lower edge 81Za of the blade louver 81a and is absorbed by the member 83a planted on the lower edge 81Za. Since it is diffused, it spontaneously evaporates there and the dripping water is prevented from dripping into the room.
[0022]
As mentioned above, although this invention was demonstrated based on one Embodiment, this invention is not limited to this. For example, although the description has been given of the case where the member 83a is implanted on the surface of the aluminum blade louver 81a, the present invention is not limited to this. For example, the blade louver 81a itself is formed of an absorbent material such as an absorbent ceramic. Is also possible.
[0023]
【The invention's effect】
According to the present invention, since the lower edge of the blade louver extends to the lower part of the lower edge of the support louver, the support louver does not require water absorption, is formed of resin, and does not require flocking. The effect of becoming a simple air conditioner is obtained.
