Description

Technical Field

[0002] Materials used in vehicle interiors include plastics, rubber, leather, adhesives, etc. These materials release VOCs (Volatile Organic Compounds), which are harmful to the human body and cause irritating odors in the car. For VOCs released by interior materials, the concentration of VOCs in the cabin is usually reduced by turning on the air conditioning external circulation, opening the windows and / or adsorbing through adsorption components. However, this way of dealing with VOCs is only effective for the moment and the effect is relatively limited. After that, as the interior materials continue to release VOCs, the concentration of VOCs in the car will continue to increase, and ventilation and / or adsorption of VOCs will be carried out again. This cyclical process takes a long time, causing users to be troubled by VOCs for a long time, resulting in a poor user experience. Summary of the invention

[0043] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0044] It should be pointed out that the embodiments of the present invention and the technical features therein may be combined with each other without conflict.

[0045] Figure 1 Schematic diagram of main steps of a method for purifying in-vehicle air according to an embodiment of the present invention.

[0046] like Figure 1 As shown, the vehicle air purification method according to the embodiment of the present invention mainly includes steps S101-S103:

[0047] Step S101, monitoring the concentration value of the target gas in the vehicle and the first temperature value in the vehicle; the source of the target gas includes the interior material of the vehicle, and the target gas can be a volatile organic compound, whose components include aldehydes, ketones, alkanes, esters, aromatic hydrocarbons, alcohols and other substances. Common formaldehyde is also one of the target gases. The in-vehicle air purification method of the embodiment of the present invention can be used to accelerate the speed of the release of the target gas (for example, volatile organic compounds) by the vehicle interior material, and at the same time adsorb the target gas through the adsorption component to purify the air in the vehicle and maintain the air quality in the vehicle. In addition, the in-vehicle air purification method of the embodiment of the present invention is executed by the in-vehicle air purification system (hereinafter referred to as the system). When the system monitors that the concentration of the target gas in the vehicle increases and reaches the processing condition, it monitors that the temperature value at this time does not reach the inflection point temperature of the interior material releasing the target gas. The system controls the vehicle air conditioner to turn on the heating function to increase the temperature in the vehicle, so that the interior material fully releases the target gas, so that the harmful components in the interior material are evaporated as soon as possible, so that the vehicle user can be relieved from the trouble of the target gas as soon as possible.

[0048] Since the execution logic of the in-vehicle air purification method of the embodiment of the present invention is that when the concentration value of the target gas reaches the first concentration threshold, the system starts the air purification operation. Therefore, when the user uses the vehicle, due to frequent window ventilation, turning on the air conditioning internal circulation, or the air conditioning external circulation, the concentration of the target gas is low, and it is not easy to trigger the system to perform the air purification operation. This also avoids the situation that the concentration of the target gas is high during the heating stage of the system performing the air purification operation, which is easy to cause harm to the user's body. At the same time, due to the execution logic of the in-vehicle air purification method, it is just suitable for the situation where the in-vehicle environment is closed after the user leaves the vehicle, so that the concentration of the target gas in the vehicle is easy to increase, and it is easy to trigger the air purification operation of the system. When the user leaves the vehicle, the air purification operation is executed, which just avoids the harm caused by the high concentration of the target gas and protects the life, health and safety of the user.

[0049] Step S102, in response to the concentration value of the target gas and the first temperature value satisfying the air conditioning heating condition, the heating function of the vehicle air conditioning is turned on. Since the release of the target gas by the interior material is a continuous process, the concentration of the target gas continues to increase when the cabin is closed. When the concentration of the target gas is low, the system does not process it first. When the concentration value of the target gas accumulates to a certain level, the system starts the air purification operation. The air purification operation of the system includes two stages: increasing the concentration of the target gas in the vehicle by heating the air conditioner and adsorbing the target gas by circulating the air conditioner.

[0050] In an optional embodiment of the present invention, the air conditioning heating condition includes: the concentration value of the target gas is greater than the preset first concentration threshold and the first temperature value is lower than the second temperature value, the second temperature value is the inflection point temperature of the target gas released by the in-vehicle material, and the second temperature value changes dynamically with the increase of the total amount of the target gas released by the in-vehicle material. Among them, the first concentration threshold is the inflection point value of the system starting the air purification operation. That is to say, when the concentration of the target gas is lower than the first concentration threshold, the air purification operation can be temporarily not performed, and when the concentration of the target gas is not lower than the first concentration threshold, the air purification operation is started. After the system starts the air purification operation, it is determined whether the temperature value in the car reaches the inflection point temperature of the interior material releasing the target gas, that is, the second temperature value. If the temperature in the car does not reach the inflection point temperature, the heating function of the vehicle air conditioner is turned on to increase the temperature in the car to the inflection point temperature, or even make the temperature in the car exceed the inflection point temperature. When the temperature of the interior material is lower than the inflection point temperature, the speed of releasing the target gas is slow, and when the temperature is not lower than the inflection point temperature, the speed of releasing the target gas is fast.

[0051] The concentration of the target gas in the car is positively correlated with the temperature. The data obtained through multiple tests over a period of time show that for every 1°C increase in temperature, the concentration of the target gas TVOC increases by about 12%. Figure 2a As shown. However, as the length of time a car is used increases, there are fewer and fewer harmful substances to be volatilized in the interior materials. Therefore, the ability of the interior materials to release the target gas becomes weaker and weaker, and even at the same temperature, the speed of releasing the target gas is reduced compared to before. Therefore, as the length of time a car is used increases, that is, as the total amount of target gas released increases, the inflection point temperature needs to be increased to further increase the speed at which the interior materials release the target gas. This requires regular adjustment of the inflection point temperature corresponding to the interior material, such as adjusting the inflection point temperature every 48 hours, that is, the second temperature value.

[0052] In addition, the standard for adjusting the inflection point temperature is: at the inflection point temperature, the time required for the concentration of the target gas to increase from the first concentration threshold to the second concentration threshold is within a preset range.

[0053] It should be noted that, when the concentration value of the target gas is greater than the preset first concentration threshold, if the monitored first temperature value itself reaches or exceeds the second temperature value, that is, the initially monitored temperature inside the vehicle has reached or exceeded the above-mentioned inflection point temperature, there is no need to turn on the heating function, and the internal circulation function of the vehicle air conditioner can be directly turned on.

[0054] Step S103, in response to the heating condition of the vehicle air conditioner satisfying the first end condition, the internal circulation of the vehicle air conditioner is turned on to allow the air in the vehicle to flow through the adsorption component used to adsorb the target gas. After the vehicle air conditioner is heated for a period of time, the temperature in the vehicle increases, and the concentration of the target gas increases. When the concentration of the target gas reaches a certain level, such as a saturated state, the heating of the vehicle air conditioner is stopped, and the internal circulation of the vehicle air conditioner is turned on to allow the air in the vehicle to flow. During the flow of the air in the vehicle, the air in the vehicle will pass through the adsorption component in the vehicle, which is used to adsorb the target gas. Through the adsorption of the adsorption component, the concentration value of the target gas in the vehicle is reduced. The adsorption component can be a filter element of the vehicle air conditioner with a target gas adsorption function.

[0055] Among them, when the heating of the vehicle air conditioner ends, it can be considered from the following three aspects: heating time, vehicle temperature and target gas concentration value. In an optional embodiment of the present invention, the first end condition includes one or more of the following conditions: the vehicle temperature is not lower than the second temperature value; the target gas concentration value is not lower than the preset second concentration threshold value, and the second concentration threshold value is greater than the first concentration threshold value; the duration of the heating function reaches the first preset duration. The first end condition may include: for example, after the heating function is turned on, the vehicle temperature rises to reach or exceed the second temperature value; as the interior material continuously releases the target gas, the concentration value of the target gas accumulates to not less than the second concentration threshold value; the heating time of the vehicle air conditioner reaches a certain duration. The vehicle air purification method of the embodiment of the present invention stops the air conditioning heating and turns on the internal circulation function of the air conditioner when one or more of the above conditions are met, so as to use the adsorption component in the vehicle to adsorb the high concentration of target gas in the vehicle, thereby achieving the purpose of air purification. Through the adsorption of the adsorption component, the concentration of the target gas in the vehicle is reduced to below the first concentration threshold, and then as the vehicle interior material releases the target gas, the concentration of the target gas continues to rise, and then the system starts a new round of air purification operation. This process is repeated until the target gas released from the vehicle interior material becomes less and less, until it can be ignored. The in-vehicle air purification method of the embodiment of the present invention shortens the duration of the entire process of interior materials releasing the target gas, shortens the duration of users being troubled by the target gas, and ensures a better vehicle experience for users, due to the technical means of promoting the release of the target gas by heating.

[0056] In order to further speed up the speed at which the target gas is adsorbed by the adsorption component, in an optional embodiment of the present invention, the method further includes turning on the blower of the vehicle air conditioner while turning on the internal circulation of the vehicle air conditioner to further increase the flow rate of the air in the vehicle. Since the internal circulation of the vehicle air conditioner can be an internal circulation achieved by the free flow of air in the vehicle, the flow rate of the air in the vehicle is relatively slow. In order to increase the flow rate of the air in the vehicle and speed up the speed at which the target gas is adsorbed by the adsorption component, the flow rate of the air in the vehicle can be accelerated by a blower to achieve rapid adsorption of the target gas by the adsorption component. Among them, the blower can be the blower of the vehicle air conditioner.

[0057] In order to further improve the air quality in the car, after the air conditioning internal circulation is turned on for a period of time, the concentration of the target gas in the car drops to a certain level, and the air conditioning external circulation can be turned on at this time to replenish fresh air in the car. In an optional embodiment of the present invention, the method further includes: in response to satisfying the second end condition of the vehicle air conditioning internal circulation, switching the vehicle air conditioning internal circulation to the external circulation; the second end condition includes: the duration of the internal circulation is turned on to reach the second preset duration, and / or the concentration value of the target gas is lower than the first concentration threshold. When to end the air conditioning internal circulation, you can refer to the duration of the internal circulation. For example, based on historical adsorption experience, you can calculate how long it takes to reduce the concentration of the target gas from the second concentration threshold to the first concentration threshold. You can refer to the calculated time length to set the duration of the internal circulation, that is, the second preset duration. When to end the air conditioning internal circulation, you can also refer to the concentration value of the target gas, such as real-time monitoring of the concentration value of the target gas in the car. When the concentration value drops below the first concentration threshold, the air conditioning internal circulation can be ended. When to end the air conditioning internal circulation, you can also refer to the duration of the internal circulation and the concentration value of the target gas at the same time. In addition, when the air conditioning internal circulation is terminated, the air conditioning external circulation is turned on to replenish fresh air in the car. It should be added that turning on the air conditioning external circulation can be replaced by opening the car windows to replenish fresh air. However, in order to ensure the safety of property in the car, turning on the air conditioning external circulation is the preferred embodiment.

[0058] The in-vehicle control and purification method is described in detail below through a specific embodiment.

[0059] like Figure 2b As shown, the in-vehicle control purification method of this embodiment mainly includes steps S2b01-S2b10:

[0060] Step S2b01: monitor the concentration of the target gas in the vehicle; the source of the target gas includes the interior materials of the vehicle.

[0061] Step S2b02: Determine whether the concentration value of the target gas is greater than a preset first concentration threshold value, if yes, execute step S2b03; if no, execute step S2b01.

[0062] Step S2b03: monitor a first temperature value inside the vehicle.

[0063] Step S2b04: Determine whether the first temperature value is lower than the second temperature value, the second temperature value is the inflection point temperature of the target gas released by the material in the vehicle, and the second temperature value changes dynamically with the increase of the total amount of target gas released by the material in the vehicle. If yes, execute step S2b05; if not, execute step S2b08.

[0064] Step S2b05: Turn on the heating function of the vehicle air conditioner.

[0065] Step S2b06: Determine whether one or more of the following heating termination conditions are met: the temperature inside the vehicle is not lower than the second temperature value; the concentration value of the target gas is not lower than the preset second concentration threshold, and the second concentration threshold is greater than the first concentration threshold; the duration of the heating function reaches the first preset duration. If yes, execute step S2b07; if no, execute step S2b05.

[0066] Step S2b07: End air conditioning heating.

[0067] Step S2b08: Turn on the air conditioning internal circulation and turn on the air conditioning blower at the same time.

[0068] Step S2b09: Determine whether the following internal circulation termination conditions are met: the duration of the internal circulation reaching a second preset duration, and / or the concentration value of the target gas is lower than the first concentration threshold. If yes, execute step S2b10; if not, execute step S2b08.

[0069] Step S2b10: Turn on the air conditioning external circulation and turn on the air conditioning blower at the same time.

[0070] The above are all embodiments of the system automatically executing the in-vehicle air purification method. In addition to the embodiments of the system automatically executing the in-vehicle air purification method, the system can also execute the in-vehicle air purification method through manual control. The following is a further detailed description of the in-vehicle air purification method executed through a manual control system through a specific application scenario.

[0071] After the user drives home from get off work, he closes the doors and windows of the vehicle and parks the vehicle in a parking space. The user's mobile terminal APP receives a system prompt, which shows that the target gas concentration in the car exceeds the standard, that is, exceeds the first concentration threshold. At the same time, the system prompts the current temperature in the car and indicates that the current temperature in the car is lower than the second temperature value, that is, the inflection point temperature. The user can control the heating function of the car air conditioner through the mobile terminal APP. After determining that the heating function is turned on for a period of time, such as 15 minutes, stop the heating function of the air conditioner, turn on the air conditioner internal circulation and start the air conditioner blower at the same time. After determining that the air conditioner internal circulation is turned on for a period of time, such as 10 minutes, switch the air conditioner internal circulation to the external circulation, and keep the air conditioner blower in working state, and turn off the car air conditioner after the external circulation continues for a period of time, such as 10 minutes. In this way, the user realizes the air purification operation through the manual control system.

[0072] The in-vehicle air purification method of an embodiment of the present invention, when the target gas concentration reaches the processing condition but the temperature has not yet reached the temperature at which the interior materials fully release the target gas, increases the temperature in the vehicle by turning on the heating function of the air conditioner, so that the interior materials of the vehicle can more fully release the target gas, and when the heating end condition is met, turns on the internal circulation of the vehicle air conditioner to allow the adsorption component in the vehicle to adsorb the target gas, thereby accelerating the speed at which the interior materials release the target gas, shortening the time for the interior materials to release the target gas, and at the same time shortening the time that the target gas bothers the user, thereby improving the user experience.

[0078] In an optional embodiment of the present invention, the system further includes a processor 304, such as Figure 4 As shown, the processor 304 is used to generate a second control instruction instructing to turn on the blower of the vehicle air conditioner while generating a first control instruction instructing to turn on the heating function of the vehicle air conditioner; the control unit 303 controls the start of the blower of the vehicle air conditioner according to the second control instruction while controlling the vehicle air conditioner to turn on the internal circulation.
