(Hereinafter referred to as front seat ECU) 301 and front seat cleaning means (hereinafter referred to as front seat cleaner) 401 are provided.
[0018]
The front seat sensor 201 captures air stains in the passenger compartment 2, for example, smoke due to smoking by an occupant with an optical sensor, determines the presence or absence of smoke based on the amount of light reflected on the smoke, and determines that there is smoke. Then, the front seat detection signal A1 is generated.
[0019]
The front seat ECU 301 generates a front seat operation signal B1 for operating a front seat cleaner 401 described later based on the front seat detection signal A1.
[0020]
The front seat cleaner 401 includes a fan motor and a filter (not shown). The fan motor is operated based on the front seat operation signal B1, and the smoke sucked from the suction port 511a is cleaned by the filter and cleaned from the blowout port 511b. Discharge as air.
[0021]
The rear seat air purifier 502 is similar to the above, and generates a rear seat detection signal A2 when the rear seat sensor 202 detects smoke, and the rear seat ECU 302 generates a rear seat operation signal B2 based on the rear seat detection signal A2. The fan motor (not shown) is generated and smoke sucked from the suction port 512a provided in the casing 512 is cleaned by a filter (not shown) and discharged as clean air from the blowout port 512b.
[0022]
Further, based on the front seat detection signal A1, the front seat ECU 301 generates an interlock signal C1 to the rear seat cleaner 402 simultaneously with the front seat operation signal B1, and the fan motor and the rear seat in the front seat cleaner 401 are generated. The fan motor in the purifier 402 is operated simultaneously.
[0023]
The operational effects of the first embodiment configured as described above will be described below. Since a plurality of sensors 201, 202, ECUs 301, 302, and purifiers 401, 402 are provided for each region in different regions of the passenger compartment 2, that is, the ceiling portion of the front seat 3 and the ceiling portion of the rear seat 4, Even if smoke is generated in the area, the cleaners 401 and 402 are operated for each area, and the smoke can be cleaned in a short time with good timing.
[0024]
Further, the conditioned air of the air conditioner 100 (including the air blown only by blowing) causes the occupant to smoke in the front seat 3, for example, and flows into the downstream side Y in the generated smoke X. Even in the case of hitting an occupant, the generated smoke X is first detected by the front seat sensor 201 in that region, and a front seat operation signal B1 is generated from the front seat ECU 301 based on the front seat detection signal A1, and the front seat cleaner 401 is turned on. It is cleaned by operating. And when smoke X generate | occur | produces in the upstream with respect to the air flow of the vehicle interior 2, the special operation | movement for suppressing the influence on a downstream is performed to the minimum. That is, the rear seat cleaner 402 is also operated simultaneously by the interlocking signal C1 generated simultaneously from the front seat ECU 301, and the smoke of the flow Y downstream is cleaned in the rear seat cleaner 402 in the Z direction. Discomfort for passengers can be suppressed.
[0025]
(Second Embodiment)
A second embodiment of the present invention is shown in FIG. In the second embodiment, the purifiers 401 and 402 are further controlled in accordance with the air conditioning mode of the air conditioner 100 as compared to the first embodiment.
[0026]
The air conditioner 100 takes in air outside the vehicle 1 from the outside air inlet 104 and discharges air-conditioned air from the outlet 106, and an unshown inside air inlet provided in the vehicle interior 2. It has an inside air circulation mode function that takes in air and circulates air that has been conditioned in the passenger compartment 2, and each mode is switched by an inside / outside air switching switch on the air conditioning panel 107.
[0027]
In addition, the position where the conditioned air is blown out is selected by switching the air flow path in the air conditioner 100. Specifically, a face mode that blows out from the face outlet 101, a bi-level mode that blows out from the face outlet 101 and the foot outlet 102, a foot mode that blows out from the foot outlet 102, a foot outlet 102 and a defroster outlet The foot differential mode that blows out from 103 and the differential mode that blows out from the defroster outlet 103 are obtained, and each mode is switched by a blow mode switching switch on the air conditioning panel 107.
[0028]
An air conditioning ECU 108 is provided that receives an air conditioning mode signal D1 generated by the inside / outside air switching switch and the blowout mode switching switch on the air conditioning panel 107 and controls the air conditioner 100 to each air conditioning mode by the air conditioning operation signal D2.
[0029]
On the other hand, an air conditioning mode distribution signal D11 based on the air conditioning mode signal D1 is input from the ECU 108 to the front seat ECU 301 in the front seat air purifier 501. The front seat ECU 301 receives the front seat detection signal A1 and the air conditioning mode. The interlock signal C1 is generated in the rear seat cleaner 402 based on the distribution signal D11. Specifically, the air conditioning mode distribution signal D11 is a signal when the air conditioning mode is the inside air circulation mode and the outlet has the face mode, that is, the face mode or the bi-level mode.
[0030]
Thus, when the air-conditioning apparatus 100 is in the inside air circulation mode and mainly air-conditioned air is blown out from the face outlet 101 (in the face or bi-level mode), the front seat 3 in the vehicle interior 2 When smoke is generated, the smoke tends to flow downstream, and the purifiers 401 and 402 are operated at the same time by the front seat activation signal B1 and the interlocking signal C1, thereby more effectively suppressing discomfort to the occupant. it can. In the case of the outside air introduction mode in which the passenger compartment 2 is in a ventilated state and the blowout mode in which the flow of smoke hardly affects the downstream side (in the case of foot, foot differential, differential mode), the interlock signal C1 is not generated, and Since the cleaners 401 and 402 operate according to the state of smoke generation in each region, the power consumption and the operation noise can be reduced.
[0031]
The condition of the air-conditioning mode for generating the interlocking signal C1 is not limited to the face or bi-level mode in the above-described inside air circulation mode, but the condition of the vehicle interior 2 when the air conditioner 100 is operated. It may be determined according to the air flow state.
[0032]
Further, in a vehicle having an air conditioner on the rear seat 4 side and the second rear seat 5 side as well, the influence of the air flow in the passenger compartment 2 is likely to occur, so the air conditioning of the rear seat is a condition for generating the interlocking signal C1. Addition even when the device is operating can further suppress discomfort to the occupant due to smoke.
[0033]
(Third embodiment)
A third embodiment of the present invention is shown in FIG. In the third embodiment, the purifiers 401 and 402 are further controlled in accordance with the open / closed state of the window of the vehicle 1 with respect to the first embodiment.
[0034]
The front window 601 and the rear window 602 of the vehicle 1 are provided with a front motor 701 and a rear motor 702 for opening and closing up and down, and the front switch 801 and the rear switch 802 are electrically operated to open and close up and down. When the windows 601 and 602 reach the fully open state or the fully closed state during the opening / closing operation, the window ECU 900 is turned off to control the opening / closing operation to stop.
[0035]
On the other hand, an open / close state signal E1 based on the open / close state of the windows 601 and 602 is input from the window ECU 900 to the front seat ECU 301 in the front seat air purifier 501. The front seat ECU 301 receives the front seat detection signal A1. The interlock signal C1 is generated in the rear seat cleaner 402 based on the open / close state signal E1. Specifically, the open / closed state signal E1 is a signal when all the windows 601 and 602 are fully closed.
[0036]
As a result, if each window 601 or 602 of the vehicle 1 is open, the smoke in the passenger compartment 2 is sucked out of the passenger compartment and has a ventilation effect, whereas the windows 601 and 602 are all closed. In this state, the smoke in the passenger compartment 2 is likely to cause discomfort to the occupant on the downstream side due to the flow of air. Therefore, by operating the cleaners 401 and 402 simultaneously with the front seat activation signal B1 and the interlocking signal C1, Can suppress discomfort. In addition, when either of the windows 601 or 602 is open, the occupant is less likely to feel discomfort due to the ventilation effect, so that the interlock signal C1 is not generated, and the cleaners 401 and 402 in each area have smoke in each area. Therefore, the power consumption and the operation noise can be further reduced.
[0037]
The condition of the open / closed state of the window that generates the interlocking signal C1 is not limited to the fully closed state described above, and may be determined according to the ventilation effect depending on the degree of opening / closing of the window.
[0038]
(Other embodiments)
As other embodiments, the number of air purifiers may be further increased as shown in FIGS. 4 to 5 in accordance with the size of the passenger compartment 2, the air flow state, and the like with respect to the first embodiment. For example, in accordance with the front seat 3, the rear seat 4, and the second rear seat 5, the air purifiers 501, 502, having the sensors 201, 202, 203, the ECUs 301, 302, 303, and the cleaners 401, 402, 403, respectively. As shown in FIG. 4 (Modification 1), the rear seat ECU 302 is based on the interlock signal C1 from the front seat ECU 301 to the rear seat cleaner 402 and the rear seat detection signal A2 based on the front seat detection signal A1. When generating the interlocking signal C2 from the front seat ECU 403 to the second rear seat cleaner 403, or as shown in FIG. 5 (Modification 2), the front seat ECU 301 and the rear seat cleaner 402 and the second seat cleaner 402 based on the front seat detection signal A1. 2 The case where the interlocking signal C1 to the rear seat cleaner 403 is generated is raised. Thereby, the air of the vehicle interior 2 can be cleaned in a short time in a timely manner, and discomfort to passengers in each seat due to smoke flowing downstream can be suppressed.
[0039]
Further, as compared with the second embodiment, as shown in FIG. 6 (Modification 3), even if the ECUs 301 and 302 of the air cleaning devices 501 and 502 are provided integrally with the air conditioning ECU 108, the same effect can be obtained. The devices 501 and 502 can be downsized.
[0040]
Further, as shown in FIG. 7 (Modification 4), the air conditioning ECU 108 and the window ECU 900 are interlocked, and the front seat ECU 301 generates an interlock signal C1 in accordance with the air conditioning mode and the open / close state of the window in addition to the front seat detection signal A1. The rear seat cleaner 402 may be operated simultaneously. Thereby, the discomfort to the occupant can be further suppressed when the smoke in the passenger compartment 2 is more susceptible to the influence of the air flow according to the air conditioning mode and the open / closed state of the window. And when there is little influence on a passenger | crew by smoke, since the cleaners 401 and 402 of each area | region operate | move according to the generation | occurrence | production state of the smoke of each area | region, respectively, power consumption and an operating sound can be reduced further.
[0041]
In each of the above embodiments, cigarette smoke has been mainly described as an example of air contamination. However, if a sensor that detects dust in the air, exhaust gas, odor, etc. is used, the cleanliness of the smoke is similarly reduced. it can.
