Below replace only discussing by ozone by ion.The discharge of being obstructed by dielectric produces ozone.Height according to the voltage that applies at first produces ion, produces ozone by aerial discharge then under higher voltage.Here set out thus, promptly have only ozone to cause the sterilization of the reality of conditioning unit member, particularly evaporator.Sterilization reaches like this, and promptly the ozone solution of Chan Shenging is in (for example on evaporator) condensed water and formation hydroxide base, its kill pathogenic bacteria, fungi and bacterium.
The device that is used for the sterilization of the member of air conditioning equipment of car, particularly evaporator of the present invention has ozone generator, it is arranged near the evaporator in conditioning unit as far as possible and can controls by electronic control package, and this electronic control package for example can be incorporated in the ozone generator or also can be incorporated in the air conditioning control device of original existence.Control setup is arranged so that when inferring according to the corresponding information of (for example via sensor or via data bus) apparatus for controlling of supply when having a kind of condition, can connect ozone generator producing on the more ozone amount meaning, under the described conditions, each choker relief valve between conditioning unit and the passenger's inner room can be estimated to keep closing the long time that maybe can be closed, that is in order to sterilize the needed time, so that there do not have ozone to enter in the passenger to be indoor.
More ozone amount is such foul smell amount, and it guarantees the failure-free sterilization in the limited time.Be different from this, so-called less ozone amount should be understood ozone amount, and it guarantees to observe the maximum limit that allows so that the protection passenger.Preferred before producing more ozone amount-when not taking place as yet-close each choker relief valve, particularly air slide valve and preferably close circulating air valve yet by control setup.
A preferred condition is the existence one empty passenger accommodation situation of possibility at least, and each choker relief valve expectation between conditioning unit under this condition and passenger's inner room keeps closing the time than length.In this case control setup is arranged so that the passenger accommodation situation that to discern a kind of sky.Control setup for example obtains corresponding information as incoming signal by means of corresponding sensor or by means of the data bus connection of leading to other electronic control packages for this reason.Handle this incoming signal in the corresponding evaluating apparatus in control setup.The result of this processing is a control corresponding of ozone generator.Control setup has a for example output stage for this reason, in order to control an electric actuator that comprises in ozone generator.If control setup is not incorporated in the ozone generator and ozone generator itself has self a electronic system, then information also can be passed to the electronic system of ozone generator, and whether the itself decision exists on-condition.
For example, when combustion engine (or ignition system, so-called binding post 15) or radio binding post (so-called binding post R) when opening circuit, control setup can infer a kind of at least may empty passenger accommodation situation.Control setup for example connects such information that obtains via the data bus of an electronics combustion engine control.
Additional or selectively, when starting central closing appliance air conditioning control device can infer a kind of at least may empty passenger accommodation situation.Control setup for example connects such information that obtains via the data bus of a central locking electronic control package.
In addition, additional or selectively, when a seat occupancy means of identification (is for example monitored by means of the video in passenger's inner room, or by means of the motor message device of theft warning device or by means of the pressure sensor in the seat, particularly by means of sensing system, it was provided with for triggering air bag originally) identify when not having the passenger, control setup can infer that one at least may empty passenger accommodation situation.Control setup for example is connected with a seat occupancy means of identification or a control setup (for example air-bag control device) via a data bus for this reason, therein in conjunction with a seat occupancy means of identification.
Another condition, promptly each choker relief valve between conditioning unit and the passenger's inner room can be estimated to keep closing the long time, preferably the situation of the cut-out of parking draught effect, parking heating effect, the effect of parking air-conditioning and waste heat effect when cutting off combustion engine.
Another condition, promptly each choker relief valve between conditioning unit and the passenger's inner room can be estimated to keep closing the long time, preferably is used for the information of vehicle electrical network operation, can start the parking customer.
Another condition, promptly each choker relief valve between conditioning unit and the passenger's inner room can be estimated to keep closing the long time, and the preferably current hour is the information between 1 and 6 points (Uhr).
Preferably close under the predetermined very first time situation at interval at each choker relief valve, control setup causes the production of a more ozone amount, and it is sterilized for failure-free, for example depends on a condensation water quantity of estimating, is essential.For example determine this time gap by experience and be stored in the control setup or by control setup according to storage or askable auxiliary data for example evaporator type code, compressor state and/or air humidity are determined.
Control setup determines that one is needed second time gap of minimizing ozone after through the very first time interval of being scheduled in further formation of the present invention, and each choker relief valve continuation keeps closing this second time gap at least.
In the of the present invention one further formation of replenishing, when no longer existing in very first time process at interval or in the process of second time gap each choker relief valve between conditioning unit and the passenger's inner room can be kept closing the condition of long time the time, control setup keeps closing the fan of startup conditioning unit under the situation of predetermined the 3rd time gap at each choker relief valve that leads to inner chamber of car.Such condition no longer exists, promptly for example when control setup is shown the information that automobile is about to start at least, for example the drawing back of automotive door, passenger accommodation by a passenger occupy, when binding post R or binding post 15 connections, engine starting or parking draught effect (Standlueft-funktion), parking heating effect, the effect of parking air-conditioning or waste heat effect are connected.
Control setup also can be arranged so that when inferring according to the corresponding information of apparatus for controlling of supply when having a kind of condition; producing a less ozone so that the protection passenger is (for example about 20ppb; limit according to sense of smell) meaning on can connect ozone generator, each choker relief valve between conditioning unit and the passenger's inner room can keep not closing maybe and can be closed under the described conditions.
Therefore reach basically by the present invention, the enforcement actv. is sterilized and can also stop sterilization in running car when stopping.
