[0028] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the present application.

[0029] With the increasingly obvious trend of global warming, in some areas, rainstorm and heavy precipitation events become more frequent. During the driving of the vehicle in the heavy precipitation environment, the problem of water entering the vehicle-mounted air conditioner is prone to occur. Water entering the vehicle-mounted air conditioner can cause the paper filter element of the air conditioner to be soaked and mildew, and produce odor. If not replaced in time, it may endanger human health, and water entering the vehicle-mounted air conditioner may burn out the electrical parts in the vehicle-mounted air conditioner, enter the passenger cabin, and cause the whole vehicle to be scrapped. Therefore, a waterproof control method is urgently needed to effectively prevent water from entering the fresh air inlet.

[0030] In view of this, the application provides a waterproof method of a vehicle-mounted air conditioner, which can transport the water flowing through the middle water flow hole to the water outlet when there is a risk of water inflow, thereby increasing the water drainage efficiency, controlling the water level in the air chamber below the fresh air outlet, and preventing water inflow of the air conditioner.

[0031] To illustrate the technical solutions of the application, specific examples are used in the following description.

[0032] Figure 1 An implementation flowchart of a waterproof method of a vehicle-mounted air conditioner is shown, which can be applied to a vehicle. The vehicle can refer to a hybrid vehicle, an electric vehicle, a fuel vehicle, or other types of vehicles, which are not limited in the application.

[0033] In the embodiments of the application, the vehicle can be configured with a vehicle-mounted air conditioner and an air chamber. The air chamber is used to provide an air inlet channel when the vehicle-mounted air conditioner is in an external circulation mode, so that external air enters the fresh air outlet to the passenger compartment through the air chamber.

[0034] When it rains, the flow path of rainwater from falling on the vehicle to leaving the vehicle is as shown in Figure 2 When the water droplets fall on the front windshield of the vehicle, part of the rainwater is thrown to both sides by the wiping action of the wiper, and the other part remains on the glass surface and flows to the ventilation cover plate under the action of gravity, and enters the air chamber below the ventilation cover plate along the water flow hole on the ventilation cover plate. The water flow hole can include a middle water flow hole and two side water flow holes. The middle water flow hole is arranged below the middle of the ventilation cover plate, and the two side water flow holes include a left side water flow hole and a right side water flow hole arranged on both sides of the ventilation cover plate.

[0035] As shown in Figure 3 In the prior art, rainwater falls from the water flow hole to the air chamber bottom plate, and due to the impact, part of the water droplets will splash to a certain height. During this process, the splashed water droplets are easy to enter the fresh air outlet under the action of fresh air. The water flowing from the left side water flow hole and the right side water flow hole flows into the air chamber water outlet arranged on both sides of the air chamber bottom plate, and the water flowing from the middle water flow hole flows to both sides due to the height difference between the central bottom plate and the two side bottom plates.

[0036] To avoid rainwater entering the fresh air outlet, in the embodiments of the application, the air chamber of the vehicle can include a baffle arranged on the slide rail, which is used to slide back and forth below the middle water flow hole of the ventilation cover plate and above the air chamber water outlet along the slide rail.

[0037] In some embodiments of the application, the baffle can include a first baffle and / or a second baffle.

[0038] Specifically, in some embodiments of the present application, the baffle includes a first baffle, which is used to slide back and forth along the slide rail below the middle water hole of the ventilation cover plate and above the air chamber outlet on the side of the fresh air inlet. For example, when the fresh air inlet is located on the left side of the vehicle, the first baffle can slide back and forth below the middle water hole and above the left air chamber outlet, thereby dispersing the water flowing into the middle water hole above the air chamber outlet on the side of the fresh air inlet.

[0039] The first baffle has a three-layer structure, and a first opening is arranged on the top layer of the three-layer structure. Specifically, the top layer of the first baffle has a convex arc surface structure upward (i.e., toward the water hole side), and the top layer can be higher than the height of the air chamber panel. The first opening is arranged on the top layer. The middle layer of the first baffle is flush with the air chamber panel. The bottom layer is made of soft material to prevent interference with the air chamber panel, and the soft material includes but is not limited to rubber, foamed plastic, and polymer material. Since the first opening is arranged on the top layer of the first baffle, on the one hand, the risk of water splashing into the fresh air inlet can be reduced, and on the other hand, the water level in the air chamber can be prevented from being too high.

[0040] In some embodiments of the present application, the baffle can include a second baffle, which is used to slide back and forth along the slide rail below the middle water hole of the ventilation cover plate and above the air chamber outlet on the opposite side of the fresh air inlet. For example, when the fresh air inlet is located on the left side of the vehicle, the second baffle can slide back and forth below the middle water hole and above the right air chamber outlet, thereby dispersing the water flowing into the middle water hole above the air chamber outlet on the opposite side of the fresh air inlet.

[0041] The second baffle also has a three-layer structure, and a second opening is arranged on the middle layer of the three-layer structure. Specifically, the top layer of the second baffle has a convex arc surface structure upward (i.e., toward the water hole side), and the top layer can be higher than the height of the air chamber panel. The middle layer of the second baffle is flush with the air chamber panel, and the second opening is arranged on the middle layer. The bottom layer is made of soft material to prevent interference with the air chamber panel, and the soft material includes but is not limited to rubber, foamed plastic, and polymer material.

[0042] The difference between the second baffle and the first baffle mainly lies in the position of the opening. Since the second baffle is arranged on the opposite side of the fresh air inlet, the risk of water splashing into the fresh air inlet on the opposite side is small, and therefore, the second opening can be arranged on the middle layer of the second baffle, on the one hand, to prevent the water level in the air chamber from being too high, and on the other hand, to increase the strength of water scraping and improve the drainage efficiency.

[0043] In actual application, the first baffle can be arranged on the side of the fresh air inlet and on the opposite side of the fresh air inlet, or the first baffle can be arranged on the side of the fresh air inlet and the second baffle can be arranged on the opposite side of the fresh air inlet, and the present application does not limit this.

[0044] No matter the first baffle or the second baffle, can slide back and forth along the slide rail below the middle water flow hole of the ventilation cover plate and above the air chamber water outlet, can quickly transport the water flow falling from the middle water flow hole to above the air chamber water outlet, so as to improve the drainage efficiency.

[0045] In some embodiments of the present application, the vehicle can also include a wiper for wiping water from the center of the air chamber bottom plate (below the middle water flow hole) to both sides (above the air chamber water outlet). Specifically, the left and right sides of the air chamber can be respectively provided with a wiper, and the step length of the wiper on both sides is the same when wiping water.

[0046] Specifically, the above water-proof method of the vehicle-mounted air conditioner can include the following steps S101 to S102.

[0047] Step S101, obtaining the first water level height of the air chamber, the first fresh air inlet height of the vehicle-mounted air conditioner and the first fresh air inlet water content.

[0048] The first water level height of the air chamber can refer to the height of the water surface in the air chamber relative to the bottom plate, which can be measured by the liquid level sensor at the bottom of the air chamber. Considering the unevenness of the bottom of the air chamber, liquid level sensors can be arranged at multiple positions on the bottom of the air chamber, and the average value of the liquid level collected by all liquid level sensors is taken as the first water level height.

[0049] The first fresh air inlet height of the vehicle-mounted air conditioner refers to the height of the fresh air inlet relative to the bottom plate, which is a kind of information that can be obtained in advance according to the vehicle type and its structure.

[0050] The first fresh air inlet water content refers to the water content around the fresh air inlet, which can be measured by the humidity sensor at the position of the fresh air inlet.

[0051] Step S102, according to the comparison result of the first water level height and the first fresh air inlet height, and the first fresh air inlet water content, controlling the baffle to slide on the slide rail.

[0052] It can be understood that the comparison result of the first water level height and the first fresh air inlet height can reflect the height difference between the water level in the air chamber and the fresh air inlet, thereby reflecting the water inlet risk of the vehicle-mounted air conditioner. The first fresh air inlet water content reflects the water content around the fresh air inlet, indicating whether the fresh air inlet has or will have water inlet problem.

[0053] According to the comparison result of the first water level height and the first fresh air inlet height, and the first fresh air inlet water content, the baffle can be controlled to slide on the slide rail, so that in the case where the water inlet problem may occur, the baffle can slide back and forth along the slide rail below the middle water flow hole of the ventilation cover plate and above the air chamber water outlet, so that the water flow flowing into the middle water flow hole can be discharged from the air chamber water outlet in time.

[0054] In the embodiments of the present application, by obtaining the first water level height of the air chamber, the first fresh air inlet height of the vehicle-mounted air conditioner, and the first water content of the fresh air inlet, the first water level height, the first fresh air inlet height, and the first water content of the fresh air inlet can reflect the current water inlet risk. According to the comparison result of the first water level height and the first fresh air inlet height, and the first water content of the fresh air inlet, the baffle is controlled to slide on the slide rail between the middle water hole below the ventilation cover plate and the water outlet above the air chamber, so that when there is a water inlet risk, the water transported by the middle water hole is transported to the water outlet, the drainage efficiency is increased, and the water level of the air chamber below the fresh air inlet is controlled to prevent the air conditioner from being waterlogged.

[0055] In some embodiments of the present application, as shown in Figure 6 According to the comparison result of the first water level height and the first fresh air inlet height, and the first water content of the fresh air inlet, the baffle is controlled to slide on the slide rail, which can include steps S601 to S603.

[0056] In step S601, if the first water level height is less than or equal to the first fresh air inlet height, and the first water content of the fresh air inlet is less than or equal to the first water content threshold, the baffle is controlled to remain in the current state.

[0057] In the embodiments of the present application, the baffle can be provided with different speed gears, and the sliding speed is different between different speed gears. Specifically, the sliding speed of the baffle can be divided into two gears, i.e. the first speed gear and the second speed gear, and the sliding speed of the second speed gear is greater than that of the first speed gear. For example, the first speed gear is 30 times between the middle water hole below the ventilation cover plate and the water outlet above the air chamber in 1 min, and the second speed gear is 60 times between the middle water hole below the ventilation cover plate and the water outlet above the air chamber in 1 min.

[0058] Specifically, if the first water level height is less than or equal to the first fresh air inlet height, and the first water content of the fresh air inlet is less than or equal to the first water content threshold, it indicates that the current water level of the air chamber does not reach the height of the fresh air inlet, and the water content around the fresh air inlet is low, at this time the baffle can be controlled to remain in the current state. The current state represents the current running state of the baffle. When the vehicle is just started, the current state is a stop state.

[0059] For different water level heights, different first water content thresholds can be set, and the first water content threshold is positively correlated with the water level height. For example, when the first water level height is less than or equal to 2 / 3 of the height of the fresh air inlet, the first water content threshold can be set to 50%. When the first water level height is greater than 2 / 3 of the height of the fresh air inlet, the first water content threshold can be set to 60%.

[0060] Step S602, if the first water level height is less than or equal to the first fresh air outlet height, and the first fresh air outlet water content is greater than the first water content threshold, the baffle is controlled to slide according to the corresponding speed gear.

[0061] Specifically, if the first water level height is less than or equal to the first fresh air outlet height, and the first fresh air outlet water content is greater than the first water content threshold, it indicates that the current air chamber water level does not reach the fresh air outlet height, but the water content around the fresh air outlet is high, at this time the baffle needs to be controlled to slide according to the corresponding speed gear.

[0062] As shown in FIG. 7, controlling the baffle to slide according to the corresponding speed gear can include steps S701 to S703. Figure 7

[0063] Step S701, if the first water level height is less than or equal to the first water level height threshold, the baffle is controlled to slide according to the first speed gear.

[0064] The first water level height threshold can be set according to actual conditions, for example, set to 1 / 3 of the first fresh air outlet height. If the first water level height is less than or equal to the first water level height threshold, it indicates that the air chamber water level height is low, at this time the baffle can be controlled to slide according to the lower first speed gear.

[0065] Step S702, if the first water level height is greater than the first water level height threshold, and the first fresh air outlet water content is less than or equal to the second water content threshold, the baffle is controlled to slide according to the first speed gear.

[0066] If the first water level height is greater than the first water level height threshold, and the first fresh air outlet water content is less than or equal to the second water content threshold, it indicates that the water content of the fresh air outlet is within a safe level, and the air chamber water level has a certain height, at this time the air chamber water level needs to be focused on, and the baffle can be controlled to slide according to the lower first speed gear.

[0067] In addition, in the case that the first water level height is greater than the first water level height threshold, and the first fresh air outlet water content is less than or equal to the second water content threshold, it can also include: after the baffle slides at the first speed gear for a first preset time, the second water level height of the air chamber is re-acquired; according to the second water level height, the speed gear of the baffle sliding is re-adjusted.

[0068] ​Specifically, the water level in the air chamber can be re-detected after the first preset time length, and according to the second water level, if the second water level is lower than the first water level, the baffle is controlled to keep the current speed gear, otherwise, the speed gear of the baffle is controlled to be increased, and the first preset time length is re-run, and the third water level is detected again. If the third water level is lower than the first water level, the baffle is controlled to keep the current speed gear, otherwise, the vehicle-mounted air conditioner is controlled to enter an internal circulation mode, and the water level and the water content of the fresh air outlet are continuously monitored. Thus, the water level in the air chamber can be monitored in time to adjust the speed gear.

[0069] In step S703, if the first water level is greater than the first water level threshold, and the first water content of the fresh air outlet is greater than the second water content threshold, the baffle is controlled to slide at the second speed gear.

[0070] If the first water level is greater than the first water level threshold, and the first water content of the fresh air outlet is greater than the second water content threshold, it indicates that the water content of the fresh air outlet exceeds the safety level, and at this time, the baffle needs to be controlled to slide at a higher second speed gear to improve the drainage efficiency.

[0071] It should be noted that the second water content threshold is greater than the first water content threshold, which can be set according to actual conditions. Similarly, for different water levels, different second water content thresholds can be set, and the second water content threshold is positively correlated with the water level. For example, when the first water level is less than or equal to 2 / 3 of the height of the fresh air outlet, the second water content threshold can be set to 60%. When the first water level is less than or equal to 2 / 3 of the height of the fresh air outlet, the second water content threshold can be set to 80%.

[0072] In addition, in the case where the first water level is greater than the first water level threshold, and the first water content of the fresh air outlet is greater than the second water content threshold, at least one of the following can be included:

[0073] 1. The baffle outside the fresh air outlet of the vehicle-mounted air conditioner is controlled to move upwards, so that the height of the fresh air outlet of the vehicle-mounted air conditioner is increased. Thus, the first water level can be lower than the second height of the fresh air outlet after the increase, and the risk of water entering is reduced.

[0074] 2. The vehicle-mounted air conditioner is controlled to enter an internal circulation mode. It can be understood that in the external circulation mode of the vehicle-mounted air conditioner, the water in the air chamber is easy to enter the passenger cabin from the fresh air outlet due to the action of fresh air. After the vehicle-mounted air conditioner enters the internal circulation mode, the risk of water in the air chamber entering the passenger cabin from the fresh air outlet due to the action of fresh air can be reduced.

[0075] Further, in the case that the first water level height is greater than the first water level height threshold and the first fresh air inlet water content is greater than the second water content threshold, the method can further comprise: after the baffle slides at the second speed gear for a second preset time length, re-acquiring the second fresh air inlet water content of the vehicle-mounted air conditioner; and re-adjusting the speed gear of the baffle sliding according to the second fresh air inlet water content.

[0076] Specifically, the fresh air inlet water content can be re-detected after the second preset time length, and according to the second fresh air inlet water content, if the second fresh air inlet water content is lower than the first fresh air inlet water content, the baffle is controlled to be lowered, otherwise, the vehicle-mounted air conditioner is controlled to enter an internal circulation mode, and the water level height and the fresh air inlet water content are continuously monitored. Thus, the fresh air inlet water content can be concerned to adjust the speed gear in time.

[0077] Step S603, if the first water level height is greater than the first fresh air inlet height, the baffle is controlled to slide at the highest speed gear.

[0078] Specifically, if the first water level height is greater than the first fresh air inlet height, it indicates that water has entered at this time, and the baffle needs to be controlled to slide at the highest speed gear, for example, the second speed gear, to drain water at the highest efficiency.

[0079] Similarly, in some embodiments of the present application, in the case that the first water level height is greater than the first fresh air inlet height, the method can further comprise at least one of the following:

[0080] 1. Controlling the baffle outside the fresh air inlet of the vehicle-mounted air conditioner to move upwards, so that the fresh air inlet height of the vehicle-mounted air conditioner is increased.

[0081] 2. Controlling the vehicle-mounted air conditioner to enter an internal circulation mode.

[0082] Further, after the baffle is controlled to slide at the highest speed gear, the method can further comprise: after the baffle slides at the highest speed gear for a third preset time length, re-acquiring the second water level height of the air chamber; if the second water level height is lowered, the highest speed gear is maintained. If the second water level height is not lowered, a prompt information is output to alarm the water-in state.

[0083] In some embodiments of the present application, the speed gear of the baffle sliding is positively correlated with the height ratio. The height ratio is the ratio between the water level height of the air chamber and the fresh air inlet height of the vehicle-mounted air conditioner. That is, the closer the water level height of the air chamber to the fresh air inlet height, the higher the speed gear of the baffle sliding should be, so as to achieve the effect of rapid drainage.

[0084] The following is described by way of example:

[0085] Case one, when the first water level height h is less than 1 / 3 of the first fresh air inlet height H, the first fresh air inlet water content δ is judged.

[0086] 1-a. When the first fresh air port moisture content δ≤50%, keep the current state unchanged;

[0087] 1-b. When the first fresh air port moisture content δ>50%, control the baffle to slide according to the first speed gear, run for 10 min, and then continue to judge the second fresh air port moisture content; if the second fresh air port moisture content δ≤50%, keep the current state running, and if the second fresh air port moisture content δ>50%, increase the speed gear of the baffle to the second speed gear.

[0088] Case two, when 1 / 3 of the first fresh air port height H≤first water level height h<2 / 3 of the first fresh air port height H, judge the first fresh air port moisture content δ;

[0089] 2-a. When the first fresh air port moisture content δ≤50%, control the baffle to slide according to the first speed gear;

[0090] 2-b. When 50%<first fresh air port moisture content δ≤60%, control the baffle to slide according to the first speed gear, detect the second water level height after 10 min, if the second water level height decreases to below 1 / 3H, keep the current mode running; otherwise, control the baffle to slide according to the second speed gear, and continue to run for 10 min, and detect the water level height again, if the new water level height≤1 / 3H, keep the current mode, if the new water level height>1 / 3H, control the vehicle-mounted air conditioner to enter the internal circulation mode, the baffle continuously slides to drain water, and the water level height and the fresh air port moisture content are continuously monitored;

[0093] 3-a. When the first fresh air port moisture content δ<60%, control the baffle to slide according to the second speed gear; it can be understood that, since the height ratio corresponding to case three (≥2 / 3) is higher than that of case two (<2 / 3), therefore, under the condition that the first fresh air port moisture content δ<60%, the speed gear is also higher;

[0095] 3-c. When the first fresh air port water content δ> 80%, control the baffle to slide according to the second speed gear, control the baffle outside the fresh air port of the vehicle-mounted air conditioner to move up by 50%, and the vehicle-mounted air conditioner enters the inner circulation mode, detect the second water level height after running for 10 min, if the second water level height is reduced to 2 / 3H or less, then control according to case two, if the second water level height has no obvious change, then keep the current state unchanged, and the water level height and the fresh air port water content are continuously monitored. If the second water level height further increases and exceeds the fresh air port height, then execute the following case four.
