Description

Technical Field

[0001] The present invention belongs to the technical field of automotive air - conditioning control, and particularly relates to a vehicle - mounted air - conditioning system with an integrated smoke exhaust function and a control method therefor. Background Art

[0002] When smoking occurs in the air - tight passenger cabin of a vehicle, due to the lack of an effective active exhaust path for smoke particles, they are likely to stay in the cabin and form a smoke aerosol pollution. Currently, the conventional solution is to forcibly open the windows or sunroof, and use the negative pressure effect generated by the high - speed air flow to achieve smoke exhaust. However, opening the windows in this way will cause uncontrolled heat exchange between the inside and outside of the vehicle, affecting the thermal comfort of the passenger cabin; moreover, after the windows are opened, the external high - speed air flow forms a turbulent effect in the cabin, and the smoke diffusion path is interfered by the Bernoulli effect, resulting in a relatively low actual exhaust efficiency. Some particles are adsorbed on the interior surfaces such as seats and ceilings due to inertial collision, forming a long - term residual pollution source. In addition, in harsh environments such as rain, snow, and sand and dust, opening the windows for smoke exhaust will directly introduce external pollutants, forcing passengers to make a passive compromise between "smoke retention" and "environmental intrusion", and the high - frequency wind noise will further exacerbate the auditory discomfort.

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application.

[0029] It should be noted that the order of description of the following embodiments does not limit the preferred order of the embodiments of the present application. In addition, in the following embodiments, the description of each embodiment has its own focus. For parts not described in detail in one embodiment, please refer to the relevant description of other embodiments.

[0030] like Figures 1-4 As shown, the first aspect of the present invention provides a vehicle air conditioning system with an integrated smoke exhaust function, comprising: a controller, a smoking recognition system, an air conditioning box, a ceiling air duct and a smoke exhaust machine, wherein: The ceiling air duct is respectively connected to the smoke exhaust fan and the air handling unit, and the smoke exhaust fan is connected to the pressure relief valve; the ceiling air outlet of the ceiling air duct is configured to be able to suck the gas in the passenger cabin reversely through the negative pressure provided by the smoke exhaust fan and discharge the gas through the pressure relief valve; when the smoking recognition system recognizes a smoking signal, the controller changes the air supply strategy of the air handling unit and the start-up strategy of the smoke exhaust fan and discharges the smoke in the passenger cabin through the ceiling air duct.

[0031] Specifically, in the present invention, the ceiling air duct is only connected to the rear air handling unit. In the case of only the front air handling unit, if smoke exhaust is required, the ceiling air duct is only connected to the smoke exhaust fan and serves as a smoke exhaust duct and cannot be used as an air supply duct for the air conditioner.

[0032] Specifically, the controller is used to control the entire air conditioning system. This controller adds a smoke exhaust blower, smoke exhaust and damper control drive, and application layer algorithm logic to the existing air conditioning system controller, and the connection relationships are all electrical signal connections, which can be either hard wire drive or LIN signal.

[0033] Specifically, the smoking recognition system is mainly used to recognize smoking signals. The present invention does not limit the recognition method of the smoking recognition system. For example, it can be infrared recognition or image recognition, etc.

[0034] Specifically, the air handling unit includes a front air handling unit and a rear air handling unit; wherein, the front air handling unit includes a front air handling unit blower, a front air handling unit mode damper, and a front air handling unit internal and external circulation damper; the rear air handling unit includes a rear air handling unit blower and a rear air handling unit mode damper.

[0035] Specifically, the pressure relief valve, also known as the vehicle pressure relief valve, is located at the rear of the vehicle and is a component for discharging the air inside the vehicle. When the air conditioner is in the external circulation mode, the external circulation air inlet is linked with the smoke exhaust fan to form a negative pressure gradient, and the incoming air mainly discharges from the outlet of the smoke exhaust fan through the pressure relief valve.

[0036] Specifically, the smoke exhaust fan includes a smoke exhaust fan blower and a smoke exhaust fan damper. The outlet of the smoke exhaust fan is arranged at a preset distance from the pressure relief valve. Specifically, the preset distance is set according to the actual situation to ensure that the outlet of the smoke exhaust fan can discharge the gas through the pressure relief valve. For example, the outlet of the smoke exhaust fan can also be directly connected to the pressure relief valve.

[0037] Specifically, one end of the ceiling air duct is connected to the interior ceiling air outlet; the other end of the ceiling air duct is respectively connected to the smoke exhaust fan and the rear air handling unit face-blowing air outlet in the air handling unit; compared with the traditional ceiling air outlet that can only supply air from the air handling unit, in the present invention, the ceiling air outlet is configured to be able to both supply air from the air handling unit and suck the gas in the passenger cabin reversely through the negative pressure provided by the smoke exhaust fan and discharge the gas through the pressure relief valve.

[0038] Here, the present invention can use the controller to change the air outlet strategy of the air-conditioning box and the start-up strategy of the smoke exhaust fan after the smoking recognition system recognizes the smoking signal. When the smoking signal needs to be discharged, the ceiling air duct and the smoke exhaust fan can be used to discharge the smoke in the passenger compartment through the pressure relief valve, thereby creating a good in-car environment.

[0039] like Figure 5 As shown, the second aspect of the present invention provides a control method for a vehicle air-conditioning system with an integrated smoke exhaust function, which is applied on the basis of an air-conditioning box and a ceiling air duct, and includes the following steps.

[0040] Step S100: configuring the controller, the smoking identification system and the smoke exhaust machine, and changing the connection relationship of the ceiling air duct.

[0041] Step S200: Connect the ceiling air duct to the smoke exhaust fan and the air conditioning box respectively, and connect the smoke exhaust fan to the pressure relief valve; wherein, the ceiling air outlet of the ceiling air duct is configured to be able to reversely suck out the gas in the passenger compartment through the negative pressure provided by the smoke exhaust fan and discharge the gas through the pressure relief valve.

[0042] Step S300: When the smoking recognition system detects a smoking signal, the controller changes the airflow strategy of the air conditioner and the activation strategy of the smoke exhaust fan, exhausting smoke from the passenger compartment through the ceiling air duct. The airflow strategy of the air conditioner specifically refers to the controller's dynamic adjustment logic for the air supply parameters of the air conditioner based on the smoking recognition signal; the activation strategy of the smoke exhaust fan specifically refers to the triggering and operating rules of the smoke exhaust fan and its associated components.

[0043] The present invention links the smoking recognition system and the smoke exhaust fan through a controller. When a smoking signal is detected, the ceiling air duct and the air-conditioning box are coordinated to control the smoke. The smoke is directionally sucked into the pressure relief valve through the negative pressure of the smoke exhaust fan for discharge, thereby quickly clearing the smoke in the cabin. At the same time, the original air supply path of the air-conditioning box is maintained to avoid thermodynamic imbalance caused by opening windows, ensure the temperature stability of the passenger compartment and the energy efficiency of the system, and take into account both environmental cleanliness and thermal comfort requirements.

[0044] In one embodiment of the present invention, the control method of the vehicle air-conditioning system with integrated smoke exhaust function also includes: configuring the air-conditioning box to include a front air-conditioning box and a rear air-conditioning box, one end of the ceiling air duct is connected to the interior ceiling air outlet; the other end of the ceiling air duct is respectively connected to the smoke exhaust fan and the rear air-conditioning box in the air-conditioning box, and the ceiling air outlet is configured to be able to supply air from the air-conditioning box, and to reversely suck out the gas in the passenger compartment through the negative pressure provided by the smoke exhaust fan and discharge the gas through the pressure relief valve.

[0045] like Figure 3 and Figure 6 As shown, in one embodiment of the present invention, the control method of the vehicle air conditioning system with integrated smoke exhaust function further includes: When the smoking recognition system fails to recognize a smoking signal and the vehicle air conditioner is not turned on, the exhaust fan blower is turned off, and both the front air conditioner box and the rear air conditioner box are closed.

[0046] Here, in this embodiment, when neither the air conditioning nor the exhaust requirement is triggered, by turning off all the actuators of the exhaust fan and the front and rear air conditioner boxes, the standby power consumption of the system and the mechanical idling loss are eliminated.

[0047] As Figure 3 and Figure 6 shown, in an embodiment of the present invention, the control method of the vehicle air conditioning system with an integrated exhaust function further includes: When the smoking recognition system fails to recognize a smoking signal and the vehicle air conditioner is turned on, the front air conditioner box mode motor, the front air conditioner box internal and external circulation motor, and the front air conditioner box blower are all controlled according to the air conditioning comfort target.

[0048] Specifically, the air conditioning comfort target control mainly calculates the vehicle interior heat load based on parameters such as ambient temperature, light, and vehicle interior temperature, and then controls the temperature, air volume, and air outlet mode (face blowing mode / foot blowing mode / defrosting mode) of the air conditioner outlet according to the heat load to achieve the comfort of the vehicle occupants.

[0049] Specifically, in Figure 3 it shows the schematic diagram of the air outlet in the foot blowing mode of the front air conditioner box with a green arrow, and the schematic diagram of the air outlet direction of the rear air conditioner box ceiling outlet with a red arrow. The colors on the carpet represent the distribution of the air conditioning temperature zones.

[0050] Here, in this embodiment, by maintaining the comfort control logic of each actuator of the front air conditioner box, the precise adjustment ability of the original temperature, circulation mode, and air volume distribution of the air conditioning system is maintained in the non-exhaust state, avoiding control strategy conflicts and energy redundant consumption caused by the intervention of the exhaust function, ensuring that the cabin thermodynamic parameters are stable within the set threshold range, realizing the intelligent compatibility and on-demand switching of the exhaust system and the conventional air conditioning function, and ensuring the continuous satisfaction of the basic comfort requirements of users.

[0051] In an embodiment of the present invention, the control method of the vehicle air conditioning system with an integrated exhaust function further includes: configuring the exhaust fan to include an exhaust fan blower and an exhaust fan air door.

[0052] Among them, in the present invention, the exhaust fan air door does not have a degree of opening, but only serves as a control switch for switching the air flow direction.

[0053] Here, in this embodiment, by setting up the modular combination of the smoke exhaust blower and the air damper, the physical isolation control of the smoke exhaust air flow and the air supply air flow of the air conditioner is realized. The air damper independently regulates the opening degree of the smoke exhaust path, and the blower precisely matches the negative pressure requirement, avoiding the energy loss caused by the air flow coupling between the traditional smoke exhaust device and the air conditioning system. At the same time, it prevents the outside air from flowing back during the smoke exhaust process, ensuring the air pressure balance in the cabin and the efficiency of directional removal of pollutants, and having both structural compactness and functional independence.

[0054] As Figure 4 and Figure 6 shown, in an embodiment of the present invention, when the smoking recognition system recognizes a smoking signal, the controller changes the air supply strategy of the air conditioner box and the startup strategy of the smoke exhaust machine and discharges the smoke in the passenger cabin through the ceiling air duct, including: When the smoking recognition system recognizes a smoking signal and the vehicle air conditioner is not turned on, the smoke exhaust blower is turned on, the front air conditioner box blower is turned on to the maximum gear, and the front air conditioner box is switched to the external circulation mode and the foot-blowing mode, and the rear air conditioner box is turned off.

[0055] Specifically, if the air conditioner is not turned on as a precondition, in order to achieve the best smoke exhaust effect, the front air conditioner blower is actively turned on, but the air supply temperature is not controlled. Switching to the foot-blowing mode is to allow fresh air to enter from the bottom of the vehicle and then go out from the ceiling to take the smoke out. For the smoke to be discharged, there must be an air inlet, otherwise the interior of the vehicle will become a vacuum state or a short-term negative pressure state, which is not conducive to the health and comfort experience of the user.

[0056] Specifically, in Figure 4 , the red arrow is the direction of the ceiling air flow, the red line is the general path of the air flow, the green arrow is the schematic of the foot-blowing air supply from the front air conditioner box, the black column is the schematic of the cigarette butt, and the colors on the carpet represent the distribution of the air conditioning temperature zones.

[0057] Here, in this embodiment, when the air conditioner is not started, through the coordinated control of the independent operation of the smoke exhaust blower and the external circulation mode and the foot-blowing mode of the front air conditioner box, a self-consistent air flow path is formed by using the external air pressure difference during vehicle driving, and the smoke is discharged directionally through the ceiling air duct, avoiding the sudden change of the cabin temperature and energy loss caused by opening the window, realizing the self-starting trigger and efficient operation of the smoke removal function under non-air-conditioning conditions, reducing the system energy consumption and maintaining the minimum thermodynamic disturbance.

[0058] As Figure 4 and Figure 6 shown, in an embodiment of the present invention, when the smoking recognition system recognizes a smoking signal, the controller changes the air supply strategy of the air conditioner box and the startup strategy of the smoke exhaust machine and discharges the smoke in the passenger cabin through the ceiling air duct, including: When the smoking recognition system recognizes a smoking signal and the vehicle air conditioner is turned on, the front air-conditioning box mode motor, the front air-conditioning box internal and external circulation motor, and the front air-conditioning box blower are all controlled according to the air-conditioning comfort target, the rear air-conditioning box is closed, the smoke exhaust fan blower is turned on, and the smoke exhaust fan damper is opened.

[0059] Among them, Figure 6 Among them, ambient temperature, vehicle interior temperature, sunlight illumination and air conditioning settings belong to non-smoke recognition requirements, and also serve as air conditioning comfort control requirements.

[0060] Here, this embodiment maintains the temperature control logic of the front air-conditioning box unchanged when the air-conditioning is in operation. By closing the rear air-conditioning box and starting the smoke exhaust fan, spatial airflow isolation is formed between the front air supply area and the ceiling smoke exhaust area. The independent air duct of the smoke exhaust fan is used to exhaust smoke in a direction-oriented manner, avoiding the airflow collision and energy loss caused by the full-power operation of the air-conditioning system in the traditional smoke exhaust mode, realizing the parallel operation of cabin temperature control and smoke removal, and ensuring functional synergy and operational economy.

[0061] Compared with the single air supply mode of the traditional air-conditioning system, the air outlet strategy and startup strategy of the present invention achieve improved smoke exhaust efficiency through a dynamic priority preemption mechanism (such as smoke exhaust instructions taking precedence over comfort control) and airflow path replanning (such as two-way reuse of ceiling air ducts).

[0062] In one embodiment of the present invention, the control method of the vehicle air conditioning system with integrated smoke exhaust function further includes the smoking recognition system re-recognizing the smoking signal when PM2.5 is lower than a preset PM value.

[0063] Specifically, PM2.5 detection is used as a signal to stop exhaust. For example, when PM2.5 falls below a preset value of 50, exhaust is stopped. Whether PM2.5 is detected before the air conditioner is turned on is irrelevant to this function. Smoking motion detection for exhaust activation can be achieved through cameras, infrared, or other recognition devices, but exhaust termination requires PM2.5 confirmation because even if a cigarette butt is extinguished, there may be a period of time when the smoke in the car is not completely exhausted.

[0064] Here, this embodiment introduces the judgment logic of the PM2.5 threshold (for example, PM2.5 is lower than 50) to dynamically monitor the particulate matter concentration during the smoke exhaust process. When the detection value is lower than the preset threshold, the smoking recognition system self-check is triggered, and the continuous smoke exhaust state caused by false triggering is released, effectively reducing the misjudgment rate caused by interference from environmental background particulate matter, achieving accurate matching of the start and stop of smoke exhaust with the actual pollution level in the cabin, forming a closed-loop control mechanism, optimizing system resource allocation and improving user experience.
