Description

  The present invention relates to an air conditioner that cools a user's head.

  Conventionally, various air conditioners mounted on automobiles and the like for cooling the head of a driver (user) have been proposed. For example, an auxiliary air conditioner that blows air cooled by a Peltier element toward a driver's head from an air outlet provided in a headrest of a driver's seat has been proposed (see, for example, Patent Document 1).

  Further, in the apparatus described in Patent Document 1, when it is detected that the driver is in a state of reduced arousal, the auxiliary air conditioner is automatically driven to direct the cooled air toward the driver's head. It is also proposed to blow out. This is an application of the fact that when the hypothalamus of the brain senses that the driver's brain temperature has decreased, the sympathetic nervous system is stimulated, thereby eliminating drowsiness. In addition to relieving drowsiness, cooling the brain is known to bring about various effects in fields other than automobile driving, such as prevention of heat stroke.

JP 2010-76652 A

  However, in the device described in Patent Document 1, since the air in the passenger compartment is blown out toward the driver's head just by passing the air through the Peltier element once, there is a limit to lowering the temperature of the blown air, There was room for improvement in order to cool the head more efficiently. Then, this invention was made | formed for the purpose of providing the air conditioner which can cool a head more efficiently.

  In the air conditioner of the present invention made to achieve the above object, the cooling unit cools the fed air. The air outlet provided around the user's head blows out the air cooled by the cooling unit, and the air inlet provided around the head blows out from the air outlet and surrounds the head. The air that has circulated is sucked into the cooling unit. Then, the cooling unit further cools the air sent from the intake port.

  In the present invention, the air circulating in the circulation around the head as described above is repeatedly cooled by the cooling unit, so that the air at a very low temperature can be circulated around the head, and the head is extremely efficient. Can be cooled.

  The cooling unit switches between a tank that stores air sent from the intake port, a cooling unit that cools the air stored in the tank, and whether air flows from the intake port to the tank. An intake valve, and a blow-off valve that switches whether air flows from the tank to the blow-out port, and closes the intake valve and the blow-off valve to cool the air stored in the tank by the cooling unit. A first control unit that alternately and repeatedly executes a first control to perform and a second control to open the intake valve and the blow-off valve and distribute the air cooled by the first control around the head. , May be further provided.

  In that case, when the first control is executed, the air stored in the tank is very well cooled by the cooling unit while being stored there, and the air circulates around the head when the second control is executed. Therefore, in this case, although intermittently, the air that has been cooled better circulates around the head, and a more remarkable effect is produced in eliminating sleepiness and the like.

  In this case, the apparatus further includes first temperature detecting means for detecting the temperature of the air stored in the tank, and the first control unit has a predetermined temperature detected by the first temperature detecting means. The first control may be executed when the temperature is higher than the temperature, and the second control may be executed when the temperature detected by the temperature detecting means is equal to or lower than the predetermined temperature. In that case, since air cooled to a predetermined temperature or less flows around the head, there may be a more remarkable effect in eliminating drowsiness.

The auxiliary air conditioner 1 may be mounted on the upper part of the passenger seat, or may be mounted on the upper part of each seat. In addition to the auxiliary air conditioner 1, the automobile in the present embodiment also includes an air conditioner (not shown) that air-conditions the entire vehicle interior.

  As shown in FIG. 1, the auxiliary air conditioner 1 includes a housing 4 in which a blowout duct 2 and an intake duct 3 are formed. In addition, a cooling unit 5 is provided in the housing 4 between the intake duct 3 and the blowout duct 2. The blowout duct 2 is an air flow path for blowing out the air cooled by the cooling unit 5 through the blowout port 21 provided around the head of the occupant J (for example, the driver). Is provided with a blowout fan 23 for blowing out the air through the blowout port 21. The air blown out from the air outlet 21 circulates around the head of the occupant J as indicated by an arrow in FIG. 1, and then is sucked through the air intake port 31 provided in the air intake duct 3, and the air intake duct 3. To the cooling unit 5.

  That is, the casing 4 defines the relative positions of the air outlet 21 so that the air outlet 21 faces the upper part of the front surface of the head of the occupant J and the air inlet 31 faces the upper part of the rear surface of the head of the occupant J. ing. And the wall surface of the housing | casing 4 which opposes the passenger | crew's J head comprises the path | route which guides the air which blown off from the blower outlet 21 to the inlet 31 between the passenger | crew's J head. The cooling unit 5 is a well-known unit that cools the air sent from the intake duct 3 by, for example, a Peltier element or the like.

  The auxiliary air conditioner 1 configured as described above is fixed to the roof R via the electrically movable front / rear movable rail 6 and the electrically powered height adjuster 7. The electric front / rear movable rail 6 supports the electric height adjuster 7 so as to be movable in the front / rear direction with respect to the roof R. The electric height adjuster 7 supports the casing 4 of the auxiliary air conditioner 1 so as to be movable in the vertical direction with respect to the electric front and rear movable rail 6.

  The following various sensors and switches are provided on the lower surface of the housing 4. That is, a power switch 81 is provided at a position adjacent to the air outlet 21 from below, and a head for detecting the air temperature around the head of the occupant J is located at a position behind the center of the casing 4 in the front-rear direction. An area temperature sensor 83 is provided. A front / rear head position sensor 85 that detects the position of the head of the occupant J relative to the front / rear direction is provided at a position closer to the front than the center of the front / rear direction of the housing 4. Further, an up / down head position sensor 87 for detecting the position of the head of the occupant J in the up / down direction is provided at a position substantially at the center of the casing 4 in the front / rear direction.

  These various sensors and switches are connected to the control unit 90 as shown in FIG. The control unit 90 is configured as a microcomputer including a CPU, a ROM, and a RAM, and based on inputs from the various sensors and switches described above, the electric front and rear movable rail 6, the electric height adjuster 7, and the blowout fan 23 described above. The cooling unit 5 is driven.

[Processing and Effects of First Embodiment]
Next, processing executed by the control unit 90 will be described. The CPU built in the control unit 90 repeatedly executes the process shown in FIG. 3 based on the program stored in the ROM built in the control unit 90 while the ignition key of the automobile is ACC or ON. To do.

  As shown in FIG. 3, when the process is started, first, in S1 (S represents a step: the same applies hereinafter), it is determined whether or not the power switch 81 of the auxiliary air conditioner 1 is on. Is done. When the power switch 81 is on (S1: Y), the front / rear position of the occupant J's head is acquired based on the signal from the front / rear head position sensor 85 in S2. In subsequent S <b> 3, the front-rear position of the auxiliary air conditioner 1 is adjusted to the position via the electrically driven front-rear movable rail 6. Specifically, the front-rear position of the housing 4 is adjusted so that the head of the occupant J is disposed between the air outlet 21 and the air inlet 31.

  In the subsequent S4, the vertical position of the head of the occupant J is acquired based on the signal from the vertical head position sensor 87. In the subsequent S5, the height of the auxiliary air conditioner 1 is adjusted to the electric height according to the position. It is adjusted via the device 7. Specifically, the air blown out from the air outlet 21 hits the forehead of the occupant J, and the air blown out from the air outlet 21 between the lower wall surface of the casing 4 and the head of the occupant J is taken into the intake port. The height of the housing 4 is adjusted so that a route for guiding to 31 is configured.

  When these position adjustments are completed, the air temperature around the head of the occupant J is detected based on the signal from the head area temperature sensor 83 in S7, and the temperature is set to a predetermined threshold value (predetermined) in S9. It is determined whether the temperature is higher than (temperature). If the temperature is higher than the threshold value (S9: Y), the blowing fan 23 is driven (on) in S10, the cooling unit 5 is driven (on) in S11, and the process proceeds to S1 described above. . The threshold value may be set by the occupant J as desired, or may be set to a fixed value in advance when the auxiliary air conditioner 1 is shipped.

  In the present embodiment, the head of the occupant J can be cooled very efficiently by executing the processes of S10 and S11. That is, by executing this process, the air cooled by the cooling unit 5 is blown out from the air outlet 21, and the air flows around the head and is then sucked in from the air inlet 31. Then, the sucked air is further cooled by the cooling unit 5 and blown out from the outlet 21 again.

  In this embodiment, the air circulating in the circumference of the head of the occupant J is repeatedly cooled by the cooling unit 5 as described above, so that the air at a very low temperature can be circulated around the head. The part can be cooled very efficiently both in terms of energy and time. In addition, in the present embodiment, since the air outlet 21 and the air inlet 31 are disposed at positions facing each other across the head of the occupant J, the air blown from the air outlet 21 and circulated around the head is used. It is possible to inhale through the intake port 31 even better. Therefore, the temperature of the air can be further lowered and the head can be cooled more efficiently.

  For example, in a normal air conditioner, it was the limit to blow out air cooled to about tens of degrees Celsius. However, in this embodiment, for example, air cooled to about minus tens of degrees Celsius is directed toward the head of the passenger J. Can be blown out. Further, the casing 4 has a shape above the head so as to avoid the head according to the shape of the head, and local air conditioning limited to the vicinity of the head is possible. For this reason, the sympathetic nerve can be stimulated by satisfactorily reducing the brain temperature of the occupant J, and the occupant J can be satisfactorily improved even in the case where a sufficient arousal state cannot be obtained with only the five sense (cool sense) stimulation May be able to awaken. Moreover, the onset of heat stroke in the vehicle can be prevented or the symptoms can be reduced.

  Further, in this process, while the power switch 81 is on (S1: Y), the position adjustment process by S2 to S5 is also repeatedly executed, so that the head of the occupant J moves while driving the automobile. In addition, the housing 4 moves following. For this reason, the auxiliary air conditioner 1 is always automatically disposed at a position suitable for cooling the head of the passenger J. When the head of the occupant J does not move, the electric front / rear movable rail 6 or the electric height adjuster 7 is not driven in S3 and S5, and the processing of S2 to S5 is substantially passed as it is. The

  Then, when the air temperature around the head becomes equal to or lower than the threshold value by the processing of S1 to S11 (S9: N), the cooling unit 5 is stopped (off) in S13, and the blowout fan 23 is stopped (off) in S14. ) And the process proceeds to S1 described above. If the power switch 81 is turned off during the process (S1: N), the process proceeds to S31, and the height of the housing 4 is returned to the initial position by the electric height adjuster 7. In subsequent S33, the blow-out fan 23 is stopped (off), and in S35, the cooling unit 5 is stopped (off), and the process is temporarily ended.

  As described above, this processing is repeatedly executed by the control unit 90 at a predetermined cycle. When this processing is started after the power switch 81 is turned on again, the above-described processing of S1 to S14 is executed. Is done. If the power switch 81 is turned off when the ignition key is turned on or off (S1: N), only the processing of S31 to S35 is executed, but the power switch 81 is turned on. When this process is started later, the processes of S1 to S14 described above are executed.

  In the first embodiment, the occupant J is the user, the cooling unit 5 is the cooling unit, the head area temperature sensor 83 is the second temperature detecting means, and the control unit 90 is the second control unit. The head position sensor 85 and the vertical head position sensor 87 correspond to head position detection means, and the electrically movable front / rear movable rail 6 and the electric height adjuster 7 correspond to movement means.

Further, in the first embodiment, the air sent from the intake duct 3 is directly cooled by the cooling unit 5 and sent directly to the blowout duct 2. However, as shown in FIG. A cold air tank 50 may be provided between the blowout duct 2. That is, in the auxiliary air conditioner 200 according to the second embodiment shown in FIG. 4, the cold air tank 50 provided inside the housing 4 is sucked into the blowing duct 2 via the blowing valve 52 and sucked via the intake valve 53. Each of the ducts 3 is connected. Note that each of the blowout valve 52 and the intake valve 53 is configured by an electromagnetic valve or the like, and switches whether air flows between the cold air tank 50 and the blowout duct 2 or the intake duct 3.

  When these position adjustments are completed, the air temperature in the cold air tank 50 is detected based on the signal from the tank internal temperature sensor 89 in S57, and whether or not the temperature is higher than a preset threshold value in S59. Is judged. If the temperature is higher than the threshold value (S59: Y), the blowing fan 23 is stopped (off) in S60, the blowing valve 52 and the intake valve 53 are closed in S61, and the process proceeds to S1 described above. Transition. This threshold value is set lower than the threshold value in S9 described above.

  In the present embodiment, the processes of S50, S60, and S61 are repeatedly performed, so that the air stored in the cold air tank 50 is extremely well cooled by the cooling unit 5 while being stored therein. When the air temperature inside the cold air tank 50 becomes equal to or lower than the threshold value by the processing of S1 to S61 (S59: N), the blowout valve 52 and the intake valve 53 are opened in S63, and the blowout fan 23 is fired in S64. Is driven (on), and the process proceeds to S1 described above. Then, the air cooled in the inside of the cold air tank 50 by the process of S1 to S61 described above is sucked from the intake port 31 after circulating around the head of the occupant J. Then, the sucked air is cooled again by the cooling unit 5 inside the cold air tank 50 and blown out from the air outlet 21.

  When the air temperature inside the cold air tank 50 again exceeds the threshold value due to the influence of the temperature in the passenger compartment (S59: Y), the air stored in the cold air tank 50 remains stored there as described above. The process (S50, S61) for cooling through the cooling unit 5 is executed.

  In the present embodiment, since air is stored in the cold air tank 50 and cooled by the cooling unit 5, although it is intermittent, it is possible to distribute the air that has been cooled better around the head of the occupant J. it can. For this reason, the same effect as that of the first embodiment is produced in this embodiment, and there may be a more remarkable effect in eliminating drowsiness.
