  Further, when such an air conditioning seat device is mounted on an automobile, there is a problem that noise is felt strongly because the blower of the air conditioning seat device is near the human body. Recent car air conditioners are automatically controlled, but because they are refrigeration cycle type refrigeration equipment, it takes a certain amount of time to exchange heat with the air to obtain cold air, that is, a rise time is required. Therefore, the blower of the car air conditioner blows with the maximum blow rate for about 15 minutes after the start of operation, but thereafter, the blower blow rate gradually decreases according to the room temperature. When the blower volume of a car air conditioner blower decreases, the noise of the air blower of the air conditioning seat device is strongly felt. Moreover, even if the vehicle speed is low or the engine speed is low, there is a problem that the noise of the blower of the air-conditioning seat device can be felt strongly.

When the temperature of the vehicle compartment is high, the vehicle compartment blower of the means blows with the maximum air flow for about 15 minutes after the start of operation, but thereafter the air flow of the vehicle compartment blower gradually decreases according to the room temperature. On the other hand, the seat air blower of the seat air-conditioning means is also operated with the maximum air flow immediately after the start of operation, but when the air flow of the passenger compartment fan decreases, the air flow of the seat fan also decreases. Therefore, when the passenger compartment temperature is high, the amount of air blown from the seat is large, giving a cool feeling to the human body, and when the passenger compartment temperature is lowered, the amount of air blown from the seat is reduced to prevent overcooling of the human body. be able to.

It is constituted by means 68.

  The dehumidifying and air-conditioning means 60 is a single dehumidifying air passage for sending dehumidified air to the seat 51 and the back 52, so that the dehumidifying air passage 67 of each of the seat 51 and the back 52 is provided with a branch passage 69 provided in the seat body 50. Connected through. Therefore, the branch passage 69 is also a means for constituting the dehumidified air passage. Reference numeral 70 denotes an exhaust port of the discharge passage 66.

  71 is a vehicle air-conditioning means composed of a refrigeration system of a refrigeration cycle, and is configured such that a compressor 72, a condenser 73, a decompressor 74, and an evaporator 75 are connected in an annular shape by piping to circulate the refrigerant. The air sucked by the vehicle compartment blower 76 having a variable capacity is heat-exchanged with the evaporator 75, and cold air-conditioned air is blown from the air outlet 77 opened in the front of the driver's seat to the vehicle compartment 59 for air conditioning. The compressor 72 rotates using the engine 78 as a drive source.

  The operation setting means 79 is an operation button (instructed to operate and stop the seat air-conditioning means 60 and the vehicle air-conditioning means 71). (Not shown), a driving capability setting button (not shown) for setting each air flow rate and capacity, a temperature setting button (not shown) for setting a target value for the driving capability of the vehicle air conditioning means 71, and the like. Yes.

  Reference numeral 80 is a control means comprising a microcomputer and its peripheral circuits, and incorporates a program for executing an operation control sequence for the seat air conditioning means 60 and the vehicle air conditioning means 71 in accordance with the instructions received from the operation setting means 79. ing. That is, the control unit 80 is electrically connected to the seat blower 61, the heating unit 65, and the air path switching unit 68 of the seat air conditioning unit 60, and the compressor 72 and the vehicle compartment blower 76 of the vehicle air conditioning unit 71, respectively.

  Then, when the control unit 80 fetches the ON / OFF instruction of the operation button of the operation setting unit 79, the control unit 80 operates and stops the interlocking operation of the seat air conditioning unit 60 and the vehicle air conditioning unit 71 and the vehicle air conditioning unit 71.

Have.

  In the above embodiment, the operation and action of the seat air-conditioning means 60 and the vehicle air-conditioning means 71, which are vehicle air-conditioners mounted on the automobile, will be described. In general, when the vehicle is parked under hot weather in summer, the room temperature of the passenger compartment 8 rises to 35 ° C. or higher, and the skin 54 of the seat body 50 also rises to about 60 ° C. When the driver gets on, when the engine 78 is started, the operation button of the operation setting unit 79 of the seat air conditioning unit 60 and the vehicle air conditioning unit 71 is operated and the driving capability setting button is operated to the maximum capacity, the control unit 80 Both the seat air-conditioning means 60 and the vehicle air-conditioning means 71 start operation. The control means 80 operates the seat air conditioning means in the dehumidifying mode as shown in FIG. In response to an instruction from the control means 80, the seat blower 61 of the seat air conditioning means 60 is rotated, and the air passage switching means 68 closes the discharge passage 66 and the dehumidified air passage 67 through the branch passage 69 to the ejection hole 53 of the skin 54. Communicate.

  The air in the passenger compartment 59 sucked from the air inlet 62 by the seat blower 61, for example, air having a temperature of 35 ° C. and a humidity of 55%, is sent to the adsorbent 63 at a flow rate of 0.6 m 3 / min. The water vapor is adsorbed and the humidity is lowered, and heat is generated by adsorption heat to become high-temperature and low-humidity air, which enters the dehumidified air passage 18 through the branch passage 69 and is diffused because it is guided to the numerous through holes 55.

  Further, the expanded high-temperature and low-humidity air is naturally deprived of heat by the constituent members of the dehumidifying air passage 67, the branch passage 69, the pad 56, and the skin 54 before reaching the ejection hole 53 of the skin 54. Heat exchange is performed, and the air becomes low humidity at a temperature of 37 ° C. and a humidity of 20%, and is ejected from the seat portion 51 of the seat body 50 and the human body seated from the ejection hole 53 of the skin 54 of the back portion 52; Flows through the thigh, waist, and back. Therefore, by evaporating the sweat on the surface of the human body, it is possible to take away the latent heat of vaporization and obtain a cooler feeling, and even if the seat body 1 is not in contact with the seating surface of the seat body 1, the human body part outside the seat that faces in the direction However, the blown-out air hits and loses the latent heat of vaporization, which can surely give a cool feeling to a wide range of human body parts.

  When the dehumidifying capacity of the dehumidifying material 63 reaches saturation, the control means 80 operates the seat air conditioning means in the regeneration mode. In response to an instruction from the control means 80, the air path switching means 68 opens the discharge passage 66, drives the heating means 65 to heat the adsorbent 63, desorbs the adsorbed moisture, and removes the air containing the desorbed moisture from the seat blower 61. Is discharged from the discharge port 70 by intermittent operation. Thereafter, the dehumidifying mode and the regeneration mode are repeated.

  On the other hand, the vehicle air-conditioning means 71 has already been started together with the seat air-conditioning means 60, and while the seat air-conditioning means 60 performs the dehumidifying air-conditioning directly on the human body, the refrigerant is compressed by the compressor 72 by the condenser 73, the decompressor 74, The air that is circulated with the evaporator 75 and the compressor 72 and is sent by the passenger compartment fan 76 that is operated at the maximum capacity and heat-exchanged in the evaporator 75 gradually decreases in temperature, rises efficiently, and the cold air blows out. From 77, the vehicle 59 is blown into the passenger compartment 59 to start air conditioning of the passenger compartment 59.

  The vehicle air-conditioning means 71 has a slow start of air-conditioning, and the room temperature of the passenger compartment 59 becomes 25 ° C. after about 15 to 30 minutes. When the room temperature decreases, the driving capacity setting button of the vehicle air-conditioning means 71 is lowered from the maximum capacity to the minimum capacity by the driver, and the air volume of the vehicle compartment fan 76 decreases. The control means 80 for reducing the air volume of the passenger compartment fan reduces the air blowing capacity of the seat fan regardless of the setting of the driving capacity setting button of the seat air conditioner 60. Therefore, when the passenger compartment temperature is high, the amount of air blown from the seat is large, giving a cool feeling to the human body, and when the passenger compartment temperature is low, the amount of air blown from the seat is reduced to prevent overcooling of the human body. be able to. Furthermore, the noise of the seat blower is not felt by the noise of the passenger compartment blower over the steady state immediately after the start of operation.

  In the case of an auto air conditioner, the driving capacity of the vehicle air conditioning means 71 is dropped by the control means 80 in accordance with a signal from the passenger compartment temperature detecting means 81. In this case as well, the control means 80 is related to the driving capacity setting button setting of the seat air conditioning means 60. The air blowing capability of the seat blower can be reduced, and the same effect as the above configuration can be obtained.

  In addition, vehicle speed detecting means 82 for detecting the traveling speed of the vehicle is provided, and the control means 80 sets the air flow rate of the seat blower according to the traveling speed of the vehicle regardless of the setting of the driving capacity setting button of the seat air conditioning means 60. In the configuration, for example, if the controller 80 is programmed to reduce the blowing capacity of the seat blower when the vehicle speed is 40 km / h or less, the blowing capacity of the seat blower is reduced when the vehicle speed is low and the noise is reduced. Noise is not felt by vehicle noise.

  Further, an engine speed detecting means 82 for detecting the engine speed is provided, and the control means 80 sets the air flow rate of the seat blower according to the engine speed regardless of the setting of the driving capacity setting button of the seat air conditioning means 60. In such a configuration, for example, when the controller 80 is programmed to reduce the blowing capacity of the seat blower when the engine speed is 1500 rpm or less, the blowing capacity of the seat blower is reduced when the engine speed is low and noise is reduced. The noise of the seat blower is not felt by the noise of the vehicle.

  Note that even when the seat body has a seat having a seat air outlet for blowing air from the seat air-conditioning means as shown in FIG. 3, the same operations and effects as in the above embodiment can be obtained.

  Further, although the adsorbent 63 is used as the dehumidifying means 64 in the above embodiment, the present invention is not limited to this. For example, the present invention may be used to condense water vapor in the air using a Peltier element or a compression refrigeration cycle. The same effect as the invention can be expected.

  Moreover, the same effect is acquired also in the structure which uses only a seat air blower as a seat air-conditioning means.

  Further, as shown in FIG. 4, the same effect can be obtained even in a configuration of a seat having a breathable skin that sucks air from the skin by a seat blower.

  As described above, the vehicle air conditioner according to the present invention can reduce the noise value felt by the passenger of the vehicle air conditioner by controlling the operation by utilizing the characteristics of the vehicle air conditioner and the seat air conditioner.
