DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic air conditioner equipped with a humidifying function.

[Conventional technology]

Conventional air conditioners for automobiles, for example,
As shown in publications such as No. 58-48519 and Japanese Unexamined Patent Publication No. 56-25012, a humidifier is installed in the air conditioning duct of an air conditioner, and humidified air is guided to the outlet along with warm air. ) has been proposed that blows out air into the vehicle interior through the air vent.

[Problem to be Solved by the Invention] However, according to the above-mentioned prior art, a part of the humidified air passing through the outlet becomes fine water particles and adheres to the wind direction change plate, and as a result, these Water particles form into water droplets and are blown forward along with the hot air, causing discomfort to passengers and causing water droplets to slip down into air conditioning ducts.

The present invention has been made in view of the above points, and its purpose is to eliminate the above-mentioned problems, and to efficiently diffuse warm air (conditioned air) and humidified air into the vehicle interior while properly mixing them. An object of the present invention is to provide an air conditioner for an automobile that can maintain a comfortable temperature and humidity condition.

[Means to solve the problem]

The present invention is configured as follows to achieve the above object. In order to make the content easier to understand,
The explanation will be given by referring to the reference numerals in the figure.

That is, the present invention is equipped with a heater 6, an air mix door 5, an air conditioning duct 7, etc., and the air outlet 7' of the air conditioning duct 7 facing into the vehicle interior has a wind direction control guide 17 with a rotation mechanism that supports the wind direction regulation guide 17. In the automotive air conditioner provided with the change body 16, a humidified air passage 11 with a humidified air source 13 is arranged separately from the air conditioning duct 7, and this humidified air passage 11 is located near the humidified air injection port 12 which serves as an outlet. is provided as a flexible duct 15, and this flexible duct 15 and humidified air injection port 12 are introduced into the air outlet 7' side passage of the air conditioning duct 7,
The humidified air injection port 12 is installed in the wind direction changing body 16, and is set to operate integrally with the wind direction change body 16, and the humidified air injection port 12 is provided with a guide for regulating the wind direction. Instead, a wind direction regulating guide 17 is arranged around the humidified air injection port 12.

[Effect]

According to the present invention having the above configuration, the warm air (air-conditioned air) TA flowing through the air conditioning duct 7 is blown out through the guides 17 of the wind direction changing body 16,
Humidifying air passage (including flexible duct 15)
The humidified air HA flowing through the wind direction changing body 11 is blown into the vehicle interior through the humidified air injection port 12 provided in the wind direction changing body 16, and after being blown out, the warm air and humidified air are mixed and discharged into the vehicle interior.

Even if the humidified air injection port 12 is attached to the wind direction changing body 16, the humidified air passage 11 and the air conditioning duct 7 are independent and do not merge even if they reach the respective air outlet ports 7' and 12. Therefore, the hot air flows through the duct outlet 7'.
Since the humidified air is not mixed with the humidified air until it is blown out from the guide 17, water droplets of the humidified air do not adhere to the guide 17, and the humidified air passage 1
Since there are no obstacles that could cause water droplets to adhere to 1, humidified air can be blown out smoothly.

In addition, since hot air and humidified air are blown out through separate passages, by making the hot air blow out faster than the humidified air, the humidified air is sucked into the warm air.
Because it can be efficiently diffused into hot air,
To diffuse humidified air at a temperature close to warm air without unevenly distributing humidified air in a vehicle interior.

Further, according to the present invention, when the wind direction changing body 16 is rotated to change the direction of the guide 17, the flexible duct 15 for humidified air is bent in a corresponding manner and maintained in that state. The mouth 12 operates integrally with the wind direction changing body 16,
Even if the direction of hot air is changed, the direction of hot air blowing out matches the direction of blowing out humidified air.

As a result, the warm air and the humidified air repeatedly interfere with each other until they reach the interior of the vehicle, further promoting the diffusion effect of the humidified air against the warm air, and
Even if the direction of the air is changed, humidified air with a temperature close to that of warm air can be diffused without unevenly distributing humidified air in the vehicle interior.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS. 1 to 4.

In the figure, 1 is the main body of the automobile air conditioner, 2 is an intake unit that sucks in external air, and 3 is an air passage section that allows intake air to pass through.
has an evaporator 4, an air mix door 5,
Heaters 6 are sequentially arranged in the air flow direction. Evaporator 4, air mix door 5 and heater 6
The temperature of the air passing through the air passing section 3 is adjusted through the air passage section 3, and the temperature-adjusted conditioned air is sent into the air conditioning duct 7, which will be described later, as warm air TA.

Reference numeral 7 denotes an air conditioning duct for guiding the warm air TA sent from the air passage section 3 into the vehicle interior. The air conditioning duct 7 is formed integrally with the air passage section 3, and a wind direction changing body 16 with a rotating mechanism is attached to a passageway on the outlet 7' side of the duct 7.

As shown in FIG. 4, the wind direction changing body 16 in this embodiment has a humidified air injection port 12 of a humidified air passage 11, which will be described later, installed in the center, and a plurality of guides 17 arranged concentrically around the humidified air outlet 12 for regulating the flow of air. It has a cylindrical shape with a spherical convex outer circumference,
It has a sliding pair structure that rotatably fits into a spherical concave surface formed on the inner surface of one end of the duct outlet 7'.

The humidified air injection port 12 is not provided with something like a guide 17.

Reference numeral 11 denotes a humidified air passage for introducing humidified air into the vehicle interior, and is formed separately from the main body 1 in advance. An intake unit 14 dedicated to humidified air is provided at one end of the humidified air passage 11, and a humidifier 13 serving as a humidified air source is provided downstream thereof, and the other end is provided with a flexible duct 15 near the outlet (humidified air injection port 12).
The flexible duct 15 and the humidified air injection port 12 are introduced into the air outlet 7' side passage of the air conditioning duct 7, and the humidified air injection port 12 is installed in the wind direction changing body 16.

The humidifying air passage 11 has a relatively small passage diameter to increase the resistance of the air passing therethrough, while the air conditioning duct 7 has a relatively large passage diameter to reduce the air resistance, thereby increasing the air resistance. The speed of the hot air TA flowing through the air duct 7 is set to be faster than the speed of the humidified air HA flowing into the humidified air passage 11.

Next, the operation of this embodiment will be explained.

Here, the case of warm air mode will be explained as an example.

The temperature of the air A sucked by the intake unit 2 is adjusted through the evaporator 4, air mix door 5, and heater 6 during the process of passing through the air passage section 3. air outlet 7' via air conditioning duct 7.
The air is sent to the side, and the direction is regulated by the guide 17 of the wind direction changing body 16, and the air is blown into the vehicle interior.

On the other hand, the air sucked by the intake unit 14 on the humidification side is generated as humidified air by the humidifier 13, and is passed through its own passage 11 (flexible duct 1).
5), the air is guided to the injection port 12 provided in the wind direction changing body 16, and is blown into the vehicle interior.

In such a blowout system, the humidified air passage 11 and the air conditioning duct 7 are connected to the respective blowout ports 1.
2 and 7', the warm air TA does not mix with the humidified air HA until it is blown into the vehicle interior, and water droplets from the humidified air HA do not adhere to the guide 17, and the humidified air Jet nozzle 12
Since there are no obstacles that could cause water droplets to adhere to the air, humidified air HA is smoothly released into the passenger compartment.

Therefore, water droplets are not scattered into the vehicle interior or slipped into the air conditioning duct 7.

In addition, the hot air TA passes through the hot air passage 7, which has lower air resistance than the humidified air passage 11, and the flow velocity is accelerated between the guides 17 when blowing out, so that the blowing velocity is faster than that of the humidified air HA. ,the result,
After blowing, warm air TA sucks humidified air HA and generates warm air.
It is possible to efficiently diffuse warm air TA and humidified air HA in the direction in which the TA blows out, and to send out a sufficient mixture of warm air TA and humidified air HA into the vehicle interior. Therefore, the humidified air is efficiently diffused into the warm air after being blown out.

In addition, the guide 1 can be rotated by rotating the wind direction changing body 16.
When the direction of the humidified air duct 7 is changed, the humidified air flexible duct 15 bends in a corresponding manner and maintains that state, so the humidified air injection port 12 operates together with the wind direction changing body 16 to change the direction of the hot air. Even if the hot air is blown out in the same direction as the humidified air, the direction in which the warm air is blown out matches the direction in which the humidified air is blown out.

For example, when the flexible duct 15 is rotated from the front-facing state shown in FIG. 2 to the upward-facing state shown in FIG. Guide 1
It is naturally directed in the same direction as 7.

Therefore, the blowing direction of hot air TA and the blowing direction of humidified air HA are always the same, and hot air TA is
Since the air is blown out surrounding the HA, both airs repeatedly interfere with each other until they reach the interior of the vehicle, further promoting the diffusion effect of the humidified air HA against the warm air TA.

Furthermore, in this embodiment, the warm air outlet (air direction changing body) 16 and the humidified air outlet 12 can be housed in the same opening, so the external appearance is simplified and the design is excellent. It can be made into a different shape.

In addition, in the above embodiment, the wind direction changing body 16 is cylindrical, but various other shapes are possible, and the rotation mechanism may also adopt an axial rotation method in addition to the spherical sliding pair. .

Alternatively, the intake unit 14 on the humidified air side may be omitted and one end of the humidified air passage 11 (one end on the upstream side of the humidifier) may be connected to the air conditioning duct 7 to introduce air.

〔Effect of the invention〕

As described above, according to the present invention, humidified air can be blown out along with warm air without causing water droplets to scatter inside the vehicle interior or falling into the air duct, etc., and in addition, the direction of the air-conditioned air (for example, warm air) Even if the air flow rate is changed, the blowing direction of the conditioned air and the humidified air are always the same, so the humidified air is efficiently diffused into the warm air, and the interior of the vehicle can be maintained at a comfortable temperature and humidity.
