[Operation of First Embodiment]
Next, the operation of the vehicle air conditioner of the present embodiment will be briefly described with reference to FIGS. Here, FIG. 7A is a diagram showing a state of the retractable cup holder when the holder is pulled out, and FIG. 7B is a diagram showing a state of the retractable cup holder when holding the cup, and FIG. (c) is a diagram showing a state of the retractable cup holder when the holder is stored (first embodiment).
[0038]
The illustrated right end face of the table 55 of the retractable cup holder 4 housed or housed in the cup holder duct 3 whose end on the opening 50 side is exposed on the front wall of the center console box is further housed in the cup holder duct 3. Alternatively, when the occupant pushes the table 55 by hand toward the retracted side (rear side of the vehicle), the right side of the table 55 from the opening 50 of the cup holder duct 3 projects into the vehicle interior from the front wall of the center console box. Comes out in front of the vehicle.
[0039]
At this time, when the container 10 is not placed on the container receiving plate 61 of the bottom holding portion 56 of the retractable cup holder 4, the bottom holding portion 56 is moved to the first withdrawal position by sliding the table 55. As shown in FIG. 7A, the panel portion 5 connected to the bottom holding portion 56 of the retractable cup holder 4 via the link 64 is stopped at a position where the communication port 48 is shut off. As a result, since the communication port 48 is blocked by the panel section 5, no cool air or hot air is supplied from the front air conditioning unit 1 to the inner part of the cup holder duct 3 via the connection duct 2.
[0040]
Next, when the occupant places the container 10 containing drinks on the container receiving plate 61 of the bottom holding portion 56 of the retractable cup holder 4 through the insertion hole 57 of the table 55, the container receiving plate 61 of the bottom holding portion 56 Lowers due to the weight of the container 10. At this time, the lower surface of the connecting plate 63, which is obliquely inclined, of the bottom surface holding portion 56 is guided by the illustrated lower end portion of the cup holder duct 3 while being in contact with the illustrated lower end portion of the opening portion 50, and slides obliquely toward the front of the vehicle. I do.
[0041]
As a result, as shown in FIG. 7B, the position of the table 55 does not change, but the bottom surface holding portion 56 further slides toward the vehicle front side to the second drawing position in the same direction as the drawing direction of the table 55. Therefore, the panel portion 5 connected to the bottom surface holding portion 56 of the retractable cup holder 4 via the link 64 slides to a position where the communication port 48 is opened. As a result, the panel portion 5 opens the communication port 48, so that cool air or hot air is supplied from the front air conditioning unit 1 to the inner part of the cup holder duct 3 via the connection duct 2.
[0042]
Next, the container 10 is taken out of the retractable cup holder 4, and the occupant hands the right end face of the table 55 projecting from the opening 50 of the cup holder duct 3 to the side to be stored or stored in the cup holder duct 3. , The table 55 slides rearward on the vehicle and is stored or stored in the cup holder duct 3. At this time, as shown in FIG. 7C, the bottom holding portion 56 of the retractable cup holder 4 is moved to the original storage position by sliding the table 55, and the panel portion 5 is moved by the restoring force of the coil spring 65. The part 5 is returned to a position where the communication port 48 is shut off. As a result, when the retractable cup holder 4 is stored (stored), the communication port 48 is blocked by the panel portion 5, so that the cool air flows from the front air conditioning unit 1 to the inner part of the cup holder duct 3 via the connection duct 2. Or, no hot air is supplied.
[0043]
Here, when the drinks (drinks) contained in the container 10 are kept cool by the retractable cup holder 4 of the present embodiment, a cool switch (not shown) installed near the center console box is operated by the occupant. It is turned ON. Then, when the passage switching door 9 is switched to the cool side, the most downstream portion of the cool air passage 51 of the blow duct 19 is fully opened, and the most downstream portion of the hot air passage 52 is completely closed.
[0044]
When the electromagnetic clutch 35 is energized (turned on) and the compressor 31 of the refrigeration cycle is started, the refrigerant circulates through the refrigeration cycle and is adiabatically expanded when passing through the valve hole of the temperature-operated expansion valve 34. The refrigerant in the liquid two-phase state flows into the evaporator 7 installed in the air conditioning duct 6. On the other hand, when a blower control voltage is applied to the blower motor 14 by the blower drive circuit, the blower motor 14 drives the centrifugal fan 15 to rotate.
[0045]
As a result, the centrifugal fan 15 sweeps out air from the inner peripheral portion toward the outer peripheral portion, and consequently from the outside air suction port 11 or the inside air suction port 12 provided on the most upstream side of the air conditioning duct 2 in the air flow direction. Aspirates outside or inside air and discharges it downstream of the centrifugal blower. When the air discharged to the downstream side of the centrifugal blower passes through the evaporator 7 of the refrigeration cycle, the refrigerant in the gas-liquid two-phase state adiabatically expanded when passing through the valve hole of the temperature-operated expansion valve 34. It is cooled by heat exchange with cold air.
[0046]
The cool air cooled by heat exchange with the refrigerant when passing through the evaporator 7 flows into the cool air passage 51 of the air duct 19 from the connection port 44 opened immediately downstream of the evaporator 7. The cool air that has flowed into the cool air passage 51 of the blower duct 19 flows into the air passage 46 of the connection duct 2 because the most downstream portion of the cool air passage 51 is opened by the passage switching door 9. The cool air that has flowed into the air passage 46 of the connection duct 2 flows into the inner part of the cup holder duct 3 from the communication port 48 because the communication port 48 is opened by the panel portion 5.
[0047]
Then, the cool air that has flowed into the inner part of the cup holder duct 3 is blown out toward the container 10 from the opening 50 of the cup holder duct 3. Thereby, the drinks (drinks) contained in the container 10 held by the retractable cup holder 4 are, for example, a vehicle interior temperature (inside air temperature) of about 25 ° C. or a vehicle outside air temperature (outside air temperature) of about 30 ° C., for example. Temperature), it is difficult to warm up, and conversely, it is kept cool for a long time by cold air blown out toward the container 10 from the opening 50 of the cup holder duct 3.
[0048]
When the drinks (drinks) contained in the container 10 are kept warm by the retractable cup holder 4 of the present embodiment, a warm switch (not shown) installed near the center console box is turned on by the occupant. Is done. Then, by switching the passage switching door 9 to the heat retaining side, the most downstream portion of the hot air passage 52 of the air duct 19 is fully opened and the most downstream portion of the cold air passage 51 is completely closed. At this time, the air mix door 26 is opened by a predetermined door opening so as to obtain an outlet temperature according to the set temperature set by the occupant, or is set at the MAX / HOT position.
