Description

[Detailed Description of the Invention] This invention relates to an improvement in preventing dew on the outer panel of an air conditioner.

That is, FIG. 1 shows a cross-sectional view of a conventional air conditioner. In the figure, 1 is the fan motor, 2 is the fan 3 attached to the fan motor 1, is the heat exchanger, 4 is the drain pan located below the heat exchanger 3, 5 is the suction grill, 6 is the blowout part, and 7 is the lower end. An inner panel located above the drain pan 4 and forming a part of the air passage, 8 a fan casing formed together with a part of the inner panel, and 9 maintaining a certain space between the inner panel 7 and the air conditioner. an exterior panel that forms the exterior surface of the

In the conventional air conditioner configured as described above, indoor air exchanges heat from the suction grill 5 through the heat exchanger 3, and is driven by the fan motor 1. The air is sucked into the fan 2 and discharged, and then sent out from the air blowing section 6 to the outside of the air conditioner. In order to prevent dew from forming on the surface of the outer panel 9 during cooling operation, air holes are provided in the upper part of the outer panel 9 and the lower part of the inner panel 7, and when the fan is driven, a part of the indoor air is transferred to the upper part of the outer panel 9. The air is sucked in through the air holes in the outer panel 9, passes through the space in the inner panel 7 of the outer panel 9, and is sucked into the fan through the air holes at the bottom of the inner panel 7. Therefore, the temperature of the outer panel 9 decreases little due to cooling operation, and dew does not form on the surface of the outer panel 9.

However, in the conventional air conditioner described above, the air sucked in to prevent dew on the outer panel 9 mixes with the heat-exchanged air after passing through the heat exchanger 3, and cools the air by exchanging heat. To reduce capacity. Deterioration of fan characteristics such as increase in fan noise due to an increase in the amount of air processed by fan 2. Since the fan motor 1 is located in the air path, during cooling operation, the capacity of the air flowing out from the air outlet part 6 of the air conditioner decreases due to heat radiation from the motor, and during heating operation, the ambient humidity of the motor 1 increases, resulting in an excessive flow of the motor 1. There were drawbacks such as temperature rise.

In view of these points, this invention attempts to prevent the exterior panel from being exposed to water by a method that does not involve suction of indoor air by a fan.

That is, FIG. 2 is a sectional view showing an embodiment of this invention.

In the figure, the fan motor 1 to the base 10 are the same as those of the conventional air conditioner described above. Reference numeral 11 denotes an inner panel 1 which has a partially convex portion facing the air passage side and has a space for attaching the main body of the motor 1 thereto.
Reference numeral 2 denotes an outer panel that has an appropriate space between it and the inner panel, has air holes 13 in a part thereof, and constitutes the outer surface of the air conditioner. Here, the main body of the motor 1 is mounted in a space between the inner panel 11 and the outer panel 12, but the shaft of the motor 1 penetrates the inner panel 11, and the fan 2 is mounted on the opposite side.

In one embodiment of the invention configured in this manner, the space between the inner panel 11 and the outer panel 12 is completely separated from the air path of the air conditioner, and the space between the inner panel 11 and the outer panel 12 is completely cut off from the air flow path of the air conditioner, and the airflow effect due to the heat dissipation of the motor 1 is prevented. Therefore, a part of the indoor air is sucked in through the air holes at the bottom of the outer panel 12 and exits to the outside through the air holes at the top of the inner panel 12, so that the outer panel 12 can prevent dew and remove air. Decrease in capacity due to wind bypass of heat exchanger 3 in the conditioner;
This has the advantage of preventing deterioration of fan characteristics such as increase in noise. In addition, the ambient temperature of the motor 1 is less susceptible to the influence of the secondary air after heat exchange.
Furthermore, as the temperature of the motor increases, the temperature effect increases, so there is an advantage that excessive temperature rise of the motor 1 can be prevented. Furthermore, since the motor 1 can be cut off from the air path, the sound generated by the motor 1 can be cut off.
This has the advantage of further reducing noise.

Furthermore, FIG. 3 is a sectional view showing another embodiment of this invention, in which the fan motor 1 to the inner panel 11 are completely the same as in the above embodiment.
Reference numeral 13 denotes an outer panel, which does not have the air holes of the outer panel 12 in the embodiment shown in FIG. In this way, even if the motor 1 is installed in a space sealed by the inner panel 11 and the outer panel 13, it is expected that the same effect as in the above embodiment can be obtained due to the air circulation in the space due to the heat radiation of the motor. can.

As explained above, this idea creates an appropriate space between the inner panel that makes up part of the outer periphery of the air passage and the outer panel that makes up the outer periphery of the aircraft, and also allows the motor to be installed within that space. By placing the main body in place, it is possible to obtain an air conditioner that does not allow dew to form on the outer panel and that operates with good characteristics.
