For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0048] Figure 1 is a schematic diagram of a washing system according to an exemplary embodiment. Figure 1As shown, it includes: a washing pot 100, a washing motor 200 and a washing pipe 300; the washing pot 100 is used to hold washing liquid; the washing pot is provided with a heat source inlet 101, a heat source outlet 102 and a heating channel running through the washing pot 100 (not shown in the figure, the shape and position of the heating channel inside the washing pot are not specifically limited in the present disclosure), the heat source inlet 101, the heat source outlet 102 are connected to the heating channel; the washing motor 200 is installed inside the washing pot 100, and the washing pipe 300 is installed outside the washing pot 100; wherein the washing motor 200 is connected to the washing pipe 300, and the washing pipe 300 is used to transport the washing liquid to the vehicle when the washing motor 200 is working; in addition, a liquid filling port 103 with a cover can be provided above the washing pot 100, and the liquid filling port is used to fill the washing liquid into the washing pot 100.

[0049] When the washing liquid heating function is turned on, the heat source is introduced into the heating channel through the heat source inlet 101 and flows out from the heat source outlet 102 to heat the washing liquid in the washing pot 100 .

[0050] Exemplarily, the washing system is applied to a vehicle and can be used to spray glass water on the windshield of the vehicle. After the spraying is completed, the windshield is cleaned by the wiper of the vehicle; or, for a vehicle with a headlight cleaning function, the washing system can also spray washing liquid on the headlights to clean the vehicle headlights. Among them, the washing pot 100 in the washing system is provided with a heat source inlet 101, a heat source outlet 102 and a heating channel running through the washing pot 100. The heating channel can be a direct connection channel between the heat source inlet 101 and the heat source outlet 102, or a channel winding in the washing pot 100. The main function is to introduce the heat source of the vehicle through the heat source inlet 101 to flow through the heating channel and flow out from the heat source outlet 102 to heat the washing liquid. Therefore, the present disclosure does not limit the shape, size and position of the heat source inlet 101, the heat source outlet 102 and the heat source channel in the washing pot 100. In addition, in the embodiments described in the present disclosure, the heat source can be a device arranged in the washing pot 100 for heating the washing liquid, or the heat source can be a device arranged outside the washing pot 100 for heating the washing liquid; the heat source can also be engine coolant, battery coolant, vehicle heater, etc. during the use of the vehicle.

[0051] Alternatively, in another possible embodiment, as Figure 1 The washing system shown may include a plurality of washing pipes 300, which are all installed outside the washing pot 100 and connected to the washing motor 200. The plurality of washing pipes 300 may lead to different positions of the vehicle, including but not limited to the front windshield, the headlights, the rear windshield, etc. of the vehicle. Or, as Figure 1The washing pipe 300 in the washing system shown may have multiple branches, each of which leads to different positions of the vehicle, including but not limited to the front windshield, the headlights, the rear windshield, etc. Alternatively, the washing system may further include multiple washing motors 200, each of which is connected to different washing pipes 300, wherein the washing pipe 300 connected to each of the multiple washing motors 200 may lead to different positions of the vehicle.

[0052] Optionally, in the above possible embodiments, Figure 1 The washing motor 200 in the washing system shown in the figure may be a bidirectional motor, which can deliver washing liquid to the vehicle through the washing pipe when rotating forward;

[0053] When the bidirectional washing motor is reversed, the washing liquid in the washing pipe 300 can be recovered into the washing pot 100 .

[0054] For example, when the washing system is working, the washing motor 200 will transport the washing liquid stored in the washing pot 100 to the vehicle through the washing pipe 300. After the washing liquid is transported, a small amount of washing liquid may remain in the washing pipe 300. In the cold winter, the washing liquid remaining in the washing pipe 300 may freeze. When the washing pipe 300 needs to transport the washing liquid again, the washing liquid may not be transported smoothly due to the frozen washing liquid in the washing pipe 300. Therefore, when the washing motor 200 is a bidirectional motor, the washing motor 200 can be reversed after the washing system is completed, so as to recover the washing liquid remaining in the washing pipe 300 into the washing pot 100.

[0055] Optionally, in the above possible embodiments, Figure 1 The washing system shown in the figure may also include an ice sensor and / or a temperature sensor, which can be installed inside the washing pot 100 to detect the state of the washing liquid in the washing pot 100; the temperature sensor can be installed inside the washing pot 100 to detect the temperature of the washing liquid in the washing pot 100.

[0056] Exemplarily, when the washing system includes an ice sensor, the ice sensor is installed inside the washing pot 100 to detect the state of the washing liquid in the washing pot 100. During the heating process of the washing liquid, if the state of the washing liquid detected by the ice sensor is solid, the washing liquid continues to be heated; if the state of the washing liquid detected by the ice sensor is liquid, the heating of the washing liquid can be stopped. Alternatively, when the washing system includes a temperature sensor, the temperature sensor is installed inside the washing pot 100 to detect the temperature of the washing liquid in the washing pot. During the heating process of the washing liquid, if the temperature of the washing liquid detected by the temperature sensor is less than or equal to a preset temperature threshold, the washing liquid continues to be heated; if the temperature of the washing liquid detected by the temperature sensor is greater than the preset temperature threshold, the heating of the washing liquid can be stopped; wherein, the preset temperature threshold can be greater than or equal to the freezing point temperature of the vehicle washing liquid. Alternatively, when the washing system includes an ice sensor and a temperature sensor, the ice sensor and the temperature sensor are both installed inside the washing kettle 100. During the heating process of the washing liquid, if the state of the washing liquid detected by the ice sensor is liquid, and the temperature of the washing liquid detected by the temperature sensor is greater than a preset temperature threshold, the heating of the washing liquid can be stopped; otherwise, the washing liquid continues to be heated.

[0057] Optionally, in the above possible embodiments, Figure 1 The washing system shown in the figure may also include an ambient temperature sensor, which may be installed in the vehicle and used to detect the ambient temperature of the vehicle. The ambient temperature may be used to determine the heating time of the washing liquid. It is understood that when the ambient temperature is lower, the amount of ice in the washing liquid may be more, so it takes a longer time to heat and thaw; when the ambient temperature is higher, the amount of ice in the washing liquid may be less, and the heating time required is shorter.

[0058] Through the above technical solution, a washing system control method is provided, which is applied to a washing system, and the washing system includes: a washing pot, a washing motor and a washing pipe; the washing pot is used to hold washing liquid; the washing pot is provided with a heat source inlet, a heat source outlet and a heating channel running through the washing pot, and the heat source inlet and the heat source outlet are connected with the heating channel; the washing motor is connected to the washing pipe, and the washing pipe is used to transport the washing liquid to the wiper of the vehicle when the washing motor is working; the method includes: obtaining a signal to start the washing liquid heating function; in response to the signal to start the washing liquid heating function, the heat source is introduced into the heating channel through the heat source inlet and flows out from the heat source outlet to heat the washing liquid in the washing pot. Through the above technical solution, in a cold environment, in order to prevent the washing liquid from freezing and icing, the heat source of the vehicle flows through the heating channel in the washing pot to thaw the washing liquid, which can solve the problem that the washing liquid cannot be sprayed out smoothly to wash the windshield in a cold environment due to freezing, and the washing motor cannot work normally due to freezing of the washing liquid and burns out or shortens its service life.

[0059] Figure 2 is a flow chart of a washing system control method according to an exemplary embodiment. This embodiment is illustrated by applying the washing system control method to a washing system, wherein the washing system can be the above-mentioned Figure 1 The washing system described in the embodiment shown. Figure 2 As shown, the method may include the following steps:

[0060] In step S11, a signal for starting the washing liquid heating function is obtained.

[0061] For example, the washing system of a vehicle is a function that is rarely used during the use of the vehicle. For example, when the driver needs to wash the windshield or the vehicle headlights, the washing liquid may freeze in the cold winter when the temperature is low. When the washing liquid freezes and the driver of the vehicle needs to wash the windshield or the vehicle headlights, the washing liquid needs to be heated. On the one hand, the vehicle can automatically turn on the washing liquid heating function according to factors such as the ambient temperature, the temperature of the washing liquid, and the state of the washing liquid. On the other hand, due to economic considerations, the driver can also turn it on when it is needed. It is understandable that the signal for obtaining the washing liquid heating function can be obtained through the vehicle-mounted system or through the vehicle ECU (Electronic Control Unit). In the embodiments described in the present disclosure, there is no limitation on the method of obtaining the signal for turning on the washing liquid heating function.

[0062] In step S12, in response to the signal for starting the washing liquid heating function, the heat source is introduced into the heating channel through the heat source inlet and flows out from the heat source outlet to heat the washing liquid in the washing pot.

[0063] Exemplarily, after the vehicle obtains a signal to start the washing liquid heating function, the heat source of the vehicle can be introduced into the heating channel through the heat source inlet and flow out from the heat source outlet to heat the washing liquid. First, the heating channel can be controlled on and off by a solenoid valve, a switch, etc. For example, a solenoid valve can be added at the heat source inlet. After the vehicle obtains a signal to start the washing liquid heating function, the solenoid valve opens, and the heat source is introduced from the heat source inlet and flows out from the heat source outlet; after the washing liquid is heated, the solenoid valve is closed, and the heat source is stopped from being introduced from the heat source inlet; or, the solenoid valve can also be installed on the route from the place where the heat source is generated on the vehicle to the heat source inlet. Secondly, the heat source can be a device set in the washing pot for heating the washing liquid, the heat source can also be a device set outside the washing pot for heating the washing liquid, and the heat source can also be engine coolant, battery coolant, vehicle heater, etc. during the use of the vehicle.

[0064] Through the above technical solution, a washing system control method is provided, which is applied to a washing system, and the washing system includes: a washing pot, a washing motor and a washing pipe; the washing pot is used to hold washing liquid; the washing pot is provided with a heat source inlet, a heat source outlet and a heating channel running through the washing pot, and the heat source inlet and the heat source outlet are connected with the heating channel; the washing motor is connected to the washing pipe, and the washing pipe is used to transport the washing liquid to the wiper of the vehicle when the washing motor is working; the method includes: obtaining a signal to start the washing liquid heating function; in response to the signal to start the washing liquid heating function, the heat source is introduced into the heating channel through the heat source inlet and flows out from the heat source outlet to heat the washing liquid in the washing pot. Through the above technical solution, in a cold environment, in order to prevent the washing liquid from freezing and icing, the heat source of the vehicle flows through the heating channel in the washing pot to thaw the washing liquid, which can solve the problem that the washing liquid cannot be sprayed out smoothly to wash the windshield in a cold environment due to freezing, and the washing motor cannot work normally due to freezing of the washing liquid and burns out or shortens its service life.

[0065] Figure 3 is a flow chart of a washing system control method according to an exemplary embodiment. Figure 3 As shown, the washing system further includes: a washing heating switch; before step S11, it also includes:

[0066] In step S13, when the heater switch of the vehicle is turned on, the washing heating switch is enabled.

[0067] Exemplarily, the washing heating switch is installed on the center console of the vehicle, and can be a push-button switch, a touch button on the center control screen of the vehicle, or a joystick under the steering wheel of the vehicle, etc. The present disclosure does not limit the style of the washing heating switch. The washing liquid heating function of the vehicle washing system usually needs to be turned on when the washing liquid is frozen. The freezing of the washing liquid usually occurs when the ambient temperature of the vehicle is low. When the ambient temperature is low, the driver of the vehicle usually needs to turn on the vehicle's warm air conditioner; when the ambient temperature is high, the washing liquid will not freeze, so there is no need to heat the washing liquid; in summary, considering that the driver accidentally touches the washing heating switch and turns on the washing heating function when the washing liquid heating function does not need to be turned on, the washing heating switch can be made available after the vehicle's warm air switch is turned on. When the warm air switch is not turned on, when the driver of the vehicle turns on the washing liquid heating function through the washing heating switch, the operation of turning on the washing liquid heating function is invalid.

[0068] For example, the heat source is engine coolant, and the washing heating switch is a push-button switch installed on the center console of the vehicle; a solenoid valve is installed at the heat source inlet, and the washing heating switch can be connected to the solenoid valve, or the washing heating switch and the solenoid valve are both connected to the controller of the vehicle; wherein, when the solenoid valve is opened, it is used to introduce the engine coolant into the heating channel through the heat source inlet and flow out from the heat source outlet to heat the washing liquid in the washing pot; when the vehicle's heater switch is not turned on, the washing heating switch is in an unavailable state. When the driver presses the washing heating switch, the solenoid valve cannot be controlled to open so that the engine coolant flows into the joining channel to heat the washing liquid in the washing pot; when the vehicle's heater switch is turned on, the washing heating switch is in an available state. When the driver presses the washing heating switch, the solenoid valve can be controlled to open so that the engine coolant flows into the joining channel to heat the washing liquid in the washing pot.

[0069] In step S14, in response to the opening action of the washing heating switch, a signal for starting the washing liquid heating function is obtained.

[0070] Figure 4 is a flow chart of a washing system control method according to an exemplary embodiment. Figure 4 As shown, after step S12, it also includes:

[0071] In step S15, when the signal for starting the washing liquid heating function is received, the timing starts;

[0072] In step S16, when the timing time reaches the set heating time, the heat source is stopped from being introduced into the heating channel to stop heating the washing liquid in the washing pot.

[0073] Exemplarily, when the driver turns on the washer fluid heating switch, the vehicle can obtain a signal to turn on the washer fluid heating function. At this time, the washer fluid heating switch can be used to control the time for heating the washer fluid; for example, the heating time can be the washer fluid heating time preset by the vehicle manufacturer, and the heating time can be determined according to the volume of the washer fluid in the washing pot; the heating time can also be a fixed heating time when the washer fluid heating switch is pressed once, and the product of the fixed time and the number of presses when pressed multiple times. Alternatively, when the washing system includes an ambient temperature sensor, the heating time can also be determined according to the ambient temperature sensor. When the ambient temperature is low, the heating time is longer, and when the ambient temperature is high, the heating time is shorter.

[0074] For example, the heat source is engine coolant, and the washing heating switch is a push-button switch installed on the center console of the vehicle; a solenoid valve is installed at the heat source entrance, and the washing heating switch can be connected to the solenoid valve, or the washing heating switch and the solenoid valve are both connected to the controller of the vehicle; when the vehicle heater switch is turned on, if the default heating time of the washing heating switch is 3 minutes, after the driver presses the washing heating switch, the solenoid valve opens and starts timing, and when the timing reaches 3 minutes, the solenoid valve is closed to stop the engine coolant from flowing into the heating channel, thereby stopping the heating of the washing fluid. Alternatively, when the vehicle's heater switch is turned on, if the default heating time for each press of the washing heating switch is 1 minute, after the driver presses the washing heating switch three times, the solenoid valve opens and starts timing. When the timing reaches 3 minutes, the solenoid valve is closed, and the engine coolant is stopped from flowing into the heating channel, thereby stopping the heating of the washing fluid. In addition, if after 2 minutes of heating, the driver presses the heating switch once again, the remaining heating time is 2 minutes. After the remaining two minutes of heating time is completed, the solenoid valve is closed, and the engine coolant is stopped from flowing into the heating channel, thereby stopping the heating of the washing fluid.

[0075] Figure 5 is a flow chart of a washing system control method according to an exemplary embodiment. Figure 5 As shown, the washing motor is a bidirectional motor; after step S12, the method further includes:

[0076] In step S17, in response to the signal for starting the washing liquid heating function, the washing motor reverse rotation function is started.

[0077] In step S18, after monitoring that the engine of the vehicle is turned off, the washing motor is controlled to rotate in reverse to recover the washing liquid in the washing pipe into the washing pot.

[0078] For example, after the washing system completes its work, a small amount of washing liquid may remain in the washing pipe. In the cold winter, the washing liquid remaining in the washing pipe may freeze. When the washing pipe needs to transport the washing liquid again, the frozen washing liquid in the washing pipe may cause the washing liquid to not be transported smoothly. Therefore, after the washing liquid heating function is turned on, the reverse function of the washing motor can be turned on. After the vehicle's engine is turned off, the washing motor can be reversed to recover the washing liquid remaining in the washing pipe into the washing pot.

[0079] Optionally, after step S18, the method further includes:

[0080] When the washing motor is controlled to start reversing, the timing starts;

[0081] After the timing time reaches the set reversal time, the washing motor is turned off.

[0082] Exemplarily, the set reversal time of the washing motor can be determined according to one or more of the length of the washing pipe, the flow direction of the washing liquid, the speed of the washing motor, etc.; when the washing system includes multiple washing pipes, the reversal time of the washing motor can be determined according to one or more of the length of the washing pipe actually used or the longest washing pipe among the multiple washing pipes, the flow direction of the washing liquid, the speed of the washing motor, etc.

[0083] Figure 6 is a flow chart of a washing system control method according to an exemplary embodiment. Figure 6 As shown, an ice sensor is provided in the washing kettle; step S12 comprises the following steps:

[0084] In step S121, in response to the signal for starting the washing liquid heating function, the state of the washing liquid is acquired through the icing sensor.

[0085] In step S122, when the washing liquid is in a solid state, the heat source is introduced into the heating channel through the heat source inlet and flows out from the heat source outlet to heat the washing liquid in the washing pot.

[0086] In step S123, when the washing liquid is in a liquid state, the heat source is stopped from being introduced into the heating channel to stop heating the washing liquid in the washing pot.

[0087] Exemplarily, when an ice sensor is installed in the washing kettle, the ice sensor is used to detect the state of the washing liquid in the washing kettle during the heating process of the washing liquid. When the washing liquid is in a solid state, the washing liquid cannot be sprayed out smoothly, so the washing system continues to heat the washing liquid; when the washing liquid is in a liquid state, the washing liquid can be sprayed out smoothly, so the washing system can turn off the heating of the washing liquid.

[0088] For example, the heat source is engine coolant, and the washing heating switch is a push-button switch installed on the center console of the vehicle; a solenoid valve is installed at the heat source inlet, and the washing heating switch can be connected to the solenoid valve, or the washing heating switch and the solenoid valve are both connected to the controller of the vehicle; when the vehicle obtains a signal to start the washing liquid heating function, the solenoid valve is controlled to open, and the state of the washing liquid is detected by the ice sensor. At this time, the engine coolant flows into the heating channel through the heat source inlet and flows out from the heat source outlet to heat the washing liquid; in this process, if the ice sensor detects that the state of the washing liquid is solid, the solenoid valve remains open to heat the washing liquid; if the ice sensor detects that the state of the washing liquid is liquid, the solenoid valve is closed to stop the engine coolant from flowing into the heating channel, thereby stopping the heating of the washing liquid.

[0089] Figure 7 is a flow chart of a washing system control method according to an exemplary embodiment. Figure 7 As shown, a temperature sensor is provided in the washing pot; step S12 comprises the following steps:

[0090] In step S124, in response to the signal for starting the washing liquid heating function, the temperature of the washing liquid is acquired through the temperature sensor.

[0091] In step S125, when the temperature of the washing liquid is less than or equal to a preset temperature threshold, the heat source is introduced into the heating channel through the heat source inlet and flows out from the heat source outlet to heat the washing liquid in the washing pot.

[0092] In step S126, when the temperature of the washing liquid is greater than the preset temperature threshold, the heat source is stopped from being introduced into the heating channel to stop heating the washing liquid in the washing pot.

[0093] Exemplarily, when a temperature sensor is installed in the washing pot, the temperature sensor is used to detect the temperature of the washing liquid in the washing pot during the heating process of the washing liquid. When the temperature of the washing liquid is less than or equal to the preset temperature threshold, the washing liquid may be in a frozen state and cannot be sprayed out smoothly. The washing system needs to continue to heat the washing liquid; when the temperature of the washing liquid is greater than the preset temperature threshold, the washing liquid may be in a liquid state and the washing liquid can be sprayed out smoothly. Therefore, the washing system can turn off the heating of the washing liquid, wherein the preset temperature threshold may be greater than or equal to the freezing point temperature of the vehicle washing liquid.

[0094] For example, the heat source is engine coolant, and the washing heating switch is a push-button switch installed on the center console of the vehicle; a solenoid valve is installed at the heat source inlet, and the washing heating switch can be connected to the solenoid valve, or the washing heating switch and the solenoid valve are both connected to the controller of the vehicle; when the vehicle obtains a signal to start the washing liquid heating function, the solenoid valve is controlled to open, and the temperature of the washing liquid is detected by the temperature sensor. At this time, the engine coolant flows into the heating channel through the heat source inlet and flows out from the heat source outlet to heat the washing liquid; in this process, if the temperature sensor detects that the temperature of the washing liquid is less than or equal to the preset temperature threshold, the solenoid valve remains open to heat the washing liquid; if the temperature sensor detects that the temperature of the washing liquid is greater than the preset temperature threshold, the solenoid valve is closed to stop the engine coolant from flowing into the heating channel, thereby stopping the heating of the washing liquid.

[0095] To summarize, an ice sensor and a temperature sensor can be installed in the washing kettle at the same time. During the heating process of the washing liquid, if the ice sensor detects that the washing liquid is in liquid state, and the temperature of the washing liquid detected by the temperature sensor is greater than a preset temperature threshold, the heating of the washing liquid can be stopped; otherwise, the washing liquid continues to be heated.

[0096] Through the above technical solution, a washing system control method is provided, which is applied to a washing system, and the washing system includes: a washing pot, a washing motor and a washing pipe; the washing pot is used to hold washing liquid; the washing pot is provided with a heat source inlet, a heat source outlet and a heating channel running through the washing pot, and the heat source inlet and the heat source outlet are connected with the heating channel; the washing motor is connected to the washing pipe, and the washing pipe is used to transport the washing liquid to the wiper of the vehicle when the washing motor is working; the method includes: obtaining a signal to start the washing liquid heating function; in response to the signal to start the washing liquid heating function, the heat source is introduced into the heating channel through the heat source inlet and flows out from the heat source outlet to heat the washing liquid in the washing pot. Through the above technical solution, in a cold environment, in order to prevent the washing liquid from freezing and icing, the heat source of the vehicle flows through the heating channel in the washing pot to thaw the washing liquid, which can solve the problem that the washing liquid cannot be sprayed out smoothly to wash the windshield in a cold environment due to freezing, and the washing motor cannot work normally due to freezing of the washing liquid and burns out or shortens its service life.
