As shown in fig. 1, the present application provides a control method of an air conditioner for a vehicle,
The air conditioner for the vehicle has a first heating defrosting mode and a second heating defrosting mode;
The control method comprises the following steps:
S101, judging whether a first heating defrosting mode is started, if so, starting the first heating defrosting mode, controlling a vehicle air conditioner to heat a part of air flow into heat flow and send the heat flow to the front row of a vehicle, and sending the other part of unheated air flow to the front windshield of the vehicle;
s102, after the first heating defrosting mode is started, judging whether the second heating defrosting mode is started, if so, starting the second heating defrosting mode, controlling the air conditioner for the vehicle to heat air flow into heat flow, and sending one part of heat flow to the front row of the vehicle and the other part of heat flow to the front windshield of the vehicle.
As shown in fig. 1, in the present embodiment, when the vehicle air conditioner is first turned on in the first heating defrost mode, a part of the airflow in the vehicle air conditioner is heated as the heat flow, and the heat flow is sent to the front row of the vehicle to heat the front row of the vehicle, thereby enhancing the comfort of the user; at the same time, the other part of the air flow is directly sent to the front windshield of the vehicle without being heated for defrosting the front windshield of the vehicle once. It will be appreciated that although the defrosting effect of the unheated air stream is poor, it still has some defrosting effect on the front windshield of the vehicle.
When the air conditioner for the vehicle starts the second heating defrosting mode, the air flows in the air conditioner for the vehicle are heated into heat flows, and a part of the heat flows are sent to the front row of the vehicle so as to continuously heat the front row of the vehicle; and the other part of the heat flow is sent to the front windshield of the vehicle for secondary defrosting of the front windshield of the vehicle. It can be appreciated that the frost on the front windshield of the vehicle can be effectively removed by defrosting the front windshield of the vehicle with heat flow, so as to improve the defrosting effect.
The control method of the air conditioner for the vehicle provided by the application can heat the front row of the vehicle when the temperature of the front row of the vehicle is low, and defrost the front windshield of the vehicle once by adopting unheated air flow; and after the front row of the vehicle is heated to a certain temperature, the front row of the vehicle can be continuously heated, and the front windshield of the vehicle is further defrosted for the second time by adopting heat flow. Therefore, the application not only can shorten the time consumption for defrosting the front windshield of the vehicle to avoid overlong waiting time of a user, but also can quickly heat the front row of the vehicle in the defrosting process to avoid uncomfortable feeling of the user, thereby achieving the purpose of enhancing the overall experience of the user.
As shown in fig. 1, the vehicle air conditioner also has a defrost mode;
the control method further comprises the following steps:
s103, judging whether a defrosting mode is started, if so, starting the defrosting mode, wherein the air conditioner for the vehicle is controlled to heat air flow into heat flow, and the heat flow is sent to a front windshield of the vehicle.
In the present embodiment, it is exemplarily described that when the vehicle air conditioner turns on the defrosting mode, the vehicle air conditioner heats the air flow to be a heat flow, and the heat flows are used for defrosting the front windshield of the vehicle, so as to further improve the defrosting effect of the vehicle air conditioner, and further achieve the purpose of further shortening the defrosting time consumption of the front windshield of the vehicle.
As shown in fig. 1, the step of determining whether to turn on the first heating defrosting mode, if yes, the step of turning on the first heating defrosting mode, that is, the step S101 includes:
Judging whether a user instruction for starting a first heating defrosting mode is received, if so, starting the first heating defrosting mode; or (b)
The method comprises the steps of presetting a first temperature, judging whether the indoor temperature of a vehicle is lower than the first temperature, judging whether a front windshield of the vehicle needs defrosting, and if yes, starting a first heating defrosting mode.
In the present embodiment, it is exemplarily explained that the "first temperature" is understood as a temperature at which the user feels cold and uncomfortable.
The vehicle user can control the air conditioning system in the vehicle, issue an instruction for starting the first heating mode, such as pressing a button or controlling on a touch screen, and the air conditioning system receives the instruction for starting the first heating mode to control the air conditioner to enter the first heating mode. It will be appreciated that the above steps may be performed in dependence on the subjective judgment of the user, and that the user may define the specific value of the first temperature according to his actual needs.
In the above, step S101 is completed by the control system. For example, the control system includes a temperature sensor, an image acquisition module, a storage module and a judgment module, wherein the temperature sensor is used for acquiring real-time temperature of a front row of a vehicle, the image acquisition module is used for acquiring real-time images of a front windshield of the vehicle, the storage module is used for storing standard images of the front windshield of the vehicle, which do not need defogging, and the judgment module is used for receiving the real-time temperature sent by the temperature sensor, the real-time images sent by the image acquisition module and the standard images sent by the storage module and judging whether the real-time temperature is lower than the first temperature or not and whether the real-time images are consistent with the standard images or not. It can be understood that if the real-time image is inconsistent with the standard image, it is determined that the front windshield of the vehicle needs to be defrosted, otherwise, it is determined that the front windshield of the vehicle does not need to be defrosted.
As shown in fig. 1, the step of determining whether to turn on the second heating defrosting mode, if yes, the step of turning on the second heating defrosting mode, that is, step S102 includes:
judging whether a user instruction for starting a second heating defrosting mode is received, if so, starting the second heating defrosting mode; or (b)
And presetting a second temperature, judging whether the indoor temperature of the vehicle is increased from the first temperature to the second temperature, and whether the front windshield of the vehicle needs to be defrosted, and if so, starting a second heating defrosting mode.
In the present embodiment, illustratively, the temperature value of the "second temperature" is greater than the "first temperature", which can be understood as that the temperature of the front row of the vehicle has gradually increased to a temperature at which the user feels warmer and more comfortable.
When the front row of the vehicle is heated to the second temperature, the vehicle user can control the air conditioning system in the vehicle to issue an instruction for starting the second heating mode, for example, a button is pressed or the control is performed on a touch screen, and the air conditioning system receives the instruction for starting the second heating mode and controls the air conditioner to enter the second heating mode. It can be understood that the above steps can still be completed depending on subjective judgment of the user, and the user can define the specific value of the second temperature according to the actual requirement.
In the above, step S102 may also be accomplished by the control system.
As shown in fig. 1, determining whether to turn on the defrosting mode, if yes, the step of turning on the defrosting mode, that is, step S103 includes:
judging whether a command of starting a defrosting mode of a user is received, if so, starting the defrosting mode; or (b)
And presetting a third temperature, judging whether the indoor temperature of the vehicle is increased to the third temperature, judging whether the front windshield of the vehicle needs to defrost, and if so, starting a defrosting mode.
In the present embodiment, it is exemplarily explained that the temperature value of the "third temperature" is greater than the "second temperature", and it is understood that the temperature of the front row of the vehicle at this time is favorable for the user to maintain the body temperature for a long time. While the difference between the defrosting mode and the first heating defrosting mode and the second defrosting mode is understood to mean that in the defrosting mode, the heat flow prepared by the air conditioner for a vehicle is used only for defrosting the front windshield of the vehicle, and is not used for heating the front row of the vehicle.
More specifically, since the user can maintain the body temperature at the third temperature for a long time without feeling cold and uncomfortable, the user can issue an instruction to start the defrosting mode, or when the air conditioning system determines that the defrosting mode needs to be started based on the indoor temperature and the frosting condition of the front windshield, the defrosting mode of the air conditioner is started. In this mode, the vehicle air conditioner is all heated the air current into the heat flow to the heat flow is all used for defrosting the preceding windscreen of vehicle, in order to further improve the defrosting effect of vehicle-mounted air conditioner, and then reaches the purpose that further shortens the defrosting time consuming of front windshield of vehicle.
As shown in fig. 1, in some embodiments, it is exemplarily illustrated that after the step S101 is performed, the step S103 may be directly performed without performing the step S102. In other words, the user may directly issue an instruction to turn on the defrost mode in the first heating defrost mode.
Specifically, when a user judges that the temperature of the front row of the automobile is lower than a first temperature and the front windshield of the automobile needs to be defrosted, the user sends an instruction to the vehicle-mounted air conditioner to start a first heating defrosting mode of the vehicle-mounted air conditioner; after the front row of the automobile is heated to the second temperature, the vehicle-mounted air conditioner can not start the second defrosting heating mode until the front row of the automobile is heated to the third temperature, and the vehicle-mounted air conditioner directly starts the defrosting mode.
As shown in fig. 1, in some embodiments, the vehicle air conditioner further has a heating mode;
the control method further comprises the following steps:
and S104, when the fact that the windshield of the vehicle does not need to be defrosted is judged, a heating mode is started, wherein the air conditioner for the vehicle heats air flow into heat flow in the heating mode and sends the heat flow to the front row of the vehicle.
In the present embodiment, it is exemplarily explained that the difference between the heating mode and the first and second heating defrost modes is understood that, in the heating mode, the heat flow prepared by the air conditioner for the vehicle is used only for heating the front row of the vehicle, not for defrosting the front windshield of the vehicle.
As shown in fig. 1, in some embodiments, it is exemplarily illustrated that the air conditioner for a vehicle may receive a user instruction to directly start a heating mode, may start a first heating defrosting mode and then start the heating mode, may start the first heating defrosting mode and the second heating defrosting mode sequentially, and then start the heating mode, and may start the first heating defrosting mode, the second heating defrosting mode and the defrosting mode sequentially, and then start the heating mode.

The warm air core 63 is circulated with a heat source, for example, the warm air core 63 is communicated with a cooling water tank of an engine of a vehicle, and the heat source is cooling water after cooling the engine. When the engine of the vehicle is running, the cooling water is heated up, and the cooling water is sent to the warm air core 63, so that the air flow flowing through the warm air core 63 can be heated.
