Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an air conditioner with an improved mechanism for blowing air into the room.

[Conventional technology]

BACKGROUND ART Conventionally, a cassette-type air conditioner is known as a one-way suction, multi-directional blowout type air conditioner.

FIG. 4 is a sectional view showing a conventional air conditioner disclosed in, for example, Japanese Utility Model Application Publication No. 58-133722, and FIG. 5 is a cross-sectional view taken from FIG. 4.

In the figure, 1 is a round cylindrical casing;
2 is a blower, which is rotated by a motor 4; 3 is a coil having a heat exchange function arranged around the outer circumference of the blower 2; 5 is a suction port for sucking indoor air by the blower 2; 6 is a suction introduction tube thereof; 8 is an annular shape formed around the outer circumference of the suction introduction tube 6. The air outlet 9 is the above coil 3
10 is an air filter installed in the suction port 5, 11 is a wind guiding guide installed on the outer periphery of the outlet 8, 12 is a wind direction adjustment vane, and 13 is an air filter installed in the air intake port 5. Operate manually.

Next, the operation will be explained. The blower 2 is rotated by the drive of the motor 4, and indoor air is sucked in through the suction port 5, passes through the air filter 10, passes through the suction introduction tube 6, and is blown onto the coil 3. This indoor air undergoes heat exchange with the coil 3, passes between the casing 1 and the introduction pipe 6, has its direction adjusted by the wind direction adjusting vane 12, and is blown out from the outlet 8 into the room. In this case, to adjust the wind direction, the angle of the wind direction adjustment vane 12 is manually adjusted to adjust the wind direction. Drain generated during heat exchange in the coil 3 is collected in the drain pan 9 and discharged to the outside.

[Problem that the invention attempts to solve]

Since conventional air conditioners are configured as described above, when adjusting the wind direction, each of the plurality of vanes has to be adjusted manually. Since there are multiple vanes, the air conditioner is located on the ceiling, and the vanes are manually adjusted, people have to use stepladders etc. to get close to the ceiling, making it very time consuming to adjust the vanes. There was once a time.

This invention was made in order to solve the above problems, and the purpose is to obtain an air conditioner at low cost in which the wind direction adjustment vanes can be automatically operated remotely.

[Means for solving problems]

The air conditioner based on this idea connects the shafts of multiple wind direction adjustment vanes with a universal joint.
A single motor can drive multiple vanes, and the wind direction can be adjusted automatically rather than manually.

[Effect]

In this invention, the plurality of wind direction adjusting vanes located at the air outlet of the air conditioner have their shafts connected by a universal joint, and are driven by one motor.

[Example of idea]

An embodiment of this invention will be described below.

In FIG. 1, 1 to 4 are the same as those of the prior art, so their explanation will be omitted. 5 is a suction port, 6 is a suction introduction cylinder,
8 is an air outlet, 11 is a wind guide, 12 is a wind direction adjustment vane arranged in a substantially annular shape, 13 is an axis of this vane, 14 is a universal joint that connects the axes of each adjacent vane, and 15 is a universal joint. This is a drive unit consisting of a motor that drives a plurality of wind direction adjustment vanes connected by.

In the air conditioner configured as described above, when the vane drive motor 15 is driven by remote control, the wind direction adjustment vane 12a directly connected to the motor of the drive section 15 is activated. When the wind direction adjustment vane 12a operates, the universal joint 1
4, the wind direction adjusting vane 12b also operates. Similarly, the force is similarly transmitted to the wind direction adjusting vanes 12c and 12d, and the plurality of wind direction adjusting vanes 12a to 12d are operated by one motor 15.

Since the motor of the drive unit 15 and the wind direction adjustment vanes 12a to 12d are connected in series with the universal joint in this way, a plurality of wind direction adjustment vanes 12a to 12d can be driven by one motor 15.
Automatic adjustment of the vanes remotely is possible.

Fig. 2 is a sectional view of an air conditioner showing another embodiment of this invention, Fig. 3a is a front view showing details of the drive unit in Fig. 2, and Fig. 3b is a side view of Fig. 3a. be. 5, 6, 8, 11-15 are the same as in the embodiment of FIG. 16 is a crank.

In the air conditioner configured in this way, the power of the motor is applied to the wind direction adjusting vane 1 by the crank 16.
The force is transmitted to both wind direction adjusting vanes 12a and 12d, and has the same effect as in the above embodiment, and since the force is transmitted in parallel, there is also the effect that there is little variation in the angles of the wind direction adjustment vanes 12a to 12d.

[Effect of idea]

As described above, according to this invention, since the motor and the plurality of wind direction adjustment vanes are connected by a universal joint, the wind direction adjustment vanes of an air conditioner can be controlled automatically rather than manually. Moreover, the structure is simple and only one motor is required, which has the effect of making the device inexpensive.
