Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioner for an automobile, and more particularly to an air conditioner for an automobile with a humidifier.

BACKGROUND ART Conventionally, a humidifier has been provided separately from an air conditioner in order to prevent a decrease in relative humidity in the interior of an automobile during winter.

Such a configuration has the following drawbacks. In other words, a) a separate blower from the air conditioner is required to send humidified air into the vehicle interior; ←) the location of the humidifier is
For example, since the humidified air is blown near the passenger compartment, the window glass may fog up, which impairs driving safety rather than eliminating the feeling of thirst in the occupants.

The present invention has been made in view of the above-mentioned drawbacks, and its object is to provide a humidifier-equipped air conditioner for an automobile that has a simple structure and does not impair driving safety.

In order to achieve the above object, an air conditioner for automobiles and vehicles according to the present invention includes an air conditioning section consisting of a blower, an evaporator, a heater, an upper part, a footwell, and a window outlet, a moisture tank, and an ultrasonic atomization unit. and a humidifying section, the moisture tank having an upper opening for blowing air from the blower, a humidified air outlet communicating with the upper center outlet, an external moisture replenishment port, and an excess moisture outlet. and a partition member for separating the upper opening and the humidified air blowing port from the external water supply port and the excess water discharge port.

An embodiment of the present invention will be described below with reference to FIG.

The air conditioner used in this example is shown, and includes an inside/outside air switching damper 2, a blower 3, an evaporator 4, a cold/warm air adjustment damper 5, a heater 6, an upper/lower outlet switching damper T1, a foot/window switching damper 8, upper side outlet 9a, 9b, upper center outlet 10, foot outlet 11, window outlet 12, and air inlet 13 from the above-mentioned blower (in rainy weather, condensed water outlet from the evaporator) 20 is a humidifier consisting of a moisture tank 21 and an ultrasonic atomization unit 22 provided at the bottom of the moisture tank. The moisture tank 21 is connected to the air inlet 13
An upper opening 23 communicating with, for example, the engine compartment 1
External water supply port tfls 25 connected to the external water supply port 24 provided in the 00 with a hose etc., humidified air blowing port 26 connected to the upper central air outlet 10 with a duct etc., moisture for discharging excess water to the engine room. Discharge port part 27, upper opening s2
3. A partition plate 30 for partitioning the atomization section 28 connected to the humidified air blowing port 26 and the discharge section 29 connected to the external supply port 25/moisture discharge port 27, and detecting the amount of water in the water tank. It consists of a float type sensor 31. The float type sensor 31 is coupled to a display section 32 and an electric circuit section that inform the occupant that the amount of water in the tank 21 has fallen below a specified amount. Also, 50 is engine room 100
This is a dash board that partitions the vehicle interior 200 and the vehicle interior 200.

In the above configuration, the present invention will be explained in detail.

First, when using it as a simple air conditioner, the blower 3
Air is blown by operating the vehicle, and air with a selected humidity is blown into the vehicle interior 200 from a selected outlet. Mainly on rainy days, the condensed water produced by the evaporator 4 enters the water tank 21 through the discharge port 13, and when it exceeds a certain specified amount, it is discharged from the discharge port 27 through the drain hose 33 to the outside of the vehicle.

Next, when using the humidifier 20, the ultrasonic atomization unit 22 is energized to make the water in the water tank i[E.

At this time, as explained above, some of the air enters the tank atomizing part 28 from the upper opening 23, so that part of the air is humidified and passes through the air outlet 26 to the upper central outlet 10.
The humidified air that is sent only to the passenger's face can quench their thirst, and the humidification is performed without fogging the window glass. When the display 32 indicates that the water in the water tank is below the specified amount, it becomes necessary to replenish water from the external replenishment port 24.
In the present invention, since the condensed water from the evaporator 4 is transferred as described above, the frequency of external water replenishment can be reduced.

The present invention is not limited to the above embodiments, and may be modified as follows. B) The humidified air outlet may be an outlet at the foot, in addition to the upper center outlet. ←) An external water supply port may be provided inside the vehicle. (c) Instead of the moisture amount detection sensor/display section, a portion of the moisture tank may be made transparent so that the amount can be determined by a colored float provided inside. B) The operation of the ultrasonic atomization unit 22 may be automated by a humidity sensor provided in the vehicle interior.

FIG. 2 is a schematic diagram of the electric circuit used in the above embodiment of the present invention. In FIG. 2, the contacts shown with broken lines represent their closed states, and the contacts shown with solid lines represent their closed states. 101 is a battery path &; 102 is an ignition switch; 103 is a proa switch that controls the rotational speed of the blower 3; 104 is an air conditioner switch that controls the operation of a computer 105 that controls the air conditioner 1;
Reference numeral 06 indicates a magnetic stitch for operating the evaporator 4, and reference numeral 107 indicates a drive switch for the humidifier 20.

Therefore, the ultrasonic atomization unit 22 according to the present invention operates only when the switches 102, 103, and 107 are all in the closed state shown by broken lines, that is, when the blower is operating. That is, the humidifier 20 is driven only when the proa switch 103 is in the closed state, regardless of the air conditioner switch 104. However, the sensor 31 and display section 32
The contact of the above ignition switch 1.02 is '□
As described above, the present invention provides an automotive air conditioner 1 and a humidifier 2.
0 and the above-mentioned air inlet 13 and upper opening 23.
Since the upper center outlet 10 and the humidified air outlet 26 are communicated with each other, and the atomization section is separated from the discharge section in the moisture tank, fogging of the window glass can be suppressed by one blower 3. It is possible to provide an excellent air conditioner with a humidifier that eliminates the thirst of passengers and reduces the frequency of external hydration.
