[0035] With the increasing popularity of automobiles in life and the gradual improvement of people's requirements for quality of life, people have gradually paid attention to automobile emissions to the outside world. When the current automobile air conditioner is working in cooling mode, the hot air sucked into the air-conditioning box by the blower inside the air-conditioning box exchanges heat with the evaporator with a very low surface temperature inside the air-conditioning box. Part of the water will condense in the heat exchange process, which is the so-called air-conditioning condensed water.

[0036] At present, the common way to deal with air-conditioning condensate in the automotive industry is to divert it to the outside of the cabin through a drain pipe under the water receiving shell at the bottom of the air-conditioning box and discharge it directly, which poses problems such as environmental pollution.

[0037] Please refer to Figure 1 , Figure 1 is a schematic diagram of the structure of a vehicle according to one or more embodiments of the present application.

[0038] To solve the above problems, the present application provides a vehicle 1, which may be a fuel vehicle, a gas vehicle or a new energy vehicle, and the new energy vehicle may be a hybrid vehicle or an extended-range vehicle, etc. The vehicle 1 may be a front-wheel drive vehicle, a four-wheel drive vehicle, etc. The vehicle 1 includes a vehicle liquid discharge device 2, which may be used to receive condensed water generated by the air conditioning system of the vehicle 1, etc., and store or discharge the condensed water.

[0039] Please refer to Figure 2-Figure 8 , Figure 2 is a first structural schematic diagram of a vehicle liquid discharge device according to one or more embodiments of the present application; Figure 3 is a second structural schematic diagram of a vehicle liquid discharge device according to one or more embodiments of the present application; Figure 4 is based on Figure 3 The schematic cross-sectional view of the vehicle liquid discharge device along the AA direction is shown; Figure 5 is based on Figure 3 The schematic cross-sectional view of the vehicle liquid discharge device along the BB direction is shown; Figure 6 is based on Figure 3 A schematic cross-sectional view of a vehicle liquid discharge device along the CC direction is shown; Figure 7 is based on Figure 3 A schematic cross-sectional view of a vehicle liquid discharge device along the DD direction is shown; Figure 8 is based on Figure 3 The shown diagram is a cross-sectional view of a vehicle liquid discharge device along the EE direction.

[0040] To solve the above problems, the present application provides a vehicle liquid discharge device 2, which includes: a shell 10, a control valve 30 and a controller 40. The shell 10 has a accommodating space 11 and a drain port 12. The accommodating space 11 is used to accommodate condensed water 20, and the drain port 12 connects the accommodating space 11 and the outside world; the control valve 30 is arranged at the drain port 12; the controller 40 is used to control the control valve 30 to block the drain port 12 in response to the vehicle 1 being in an indoor state, and the controller 40 is used to control the control valve 30 to open at least part of the drain port 12 in response to the vehicle 1 being in an outdoor state.

[0041] The shape of the housing 10 may include, but is not limited to, any shape such as square, cylindrical, etc. The housing 10 is formed with a receiving space 11, which can be used to receive condensed water 20, which can be a condensed liquid generated by the air conditioning system of the vehicle 1. The drain port 12 connects the receiving space 11 with the outside, and the condensed water 20 can exit the receiving space 11 through the drain port 12 to be discharged to the outside. In some application scenarios, the housing 10 also has a water inlet, which can be connected to a condensed water 20 generating device so that the condensed water 20 enters the receiving space 11 through the water inlet. Optionally, the water inlet and the drain port 12 may be spaced apart in the direction of gravity, the water inlet is located upstream in the direction of gravity, and the drain port 12 is located downstream in the direction of gravity, so that the condensed water 20 can enter and exit the receiving space 11. The control valve 30 can open or block the drain port 12 under the control of the controller 40. The indoor state may refer to the vehicle 1 being located inside a building, such as being located in an indoor parking lot, etc. The outdoor state may refer to the vehicle 1 being located outside a building, such as being located in an open air environment, etc. In some application scenarios, the location information of the vehicle 1 can be used to determine whether the vehicle 1 is in an indoor state or an outdoor state. For example, the location information of the vehicle 1 can be obtained through the positioning device of the vehicle 1, such as GPS, and the location information can be used to determine whether the vehicle 1 is in an indoor state or an outdoor state. Furthermore, other environmental information collection devices of the vehicle 1, such as various sensors, can also be used to determine whether the vehicle 1 is in an indoor state or an outdoor state. The controller 40 can control the control valve 30. It can be understood that in response to the vehicle 1 being in an indoor state, the controller 40 controls the control valve 30 to block the drain port 12 to prevent the condensed water 20 from being discharged. In response to the vehicle 1 being in an outdoor state, the controller 40 controls the control valve 30 to open at least part of the drain port 12 so as to discharge the condensed water 20 to the outdoor environment.

[0042] Through the above-mentioned embodiment, when the vehicle 1 is in the outdoor state, the controller 40 controls the control valve 30 to open at least part of the drain port 12 to facilitate the discharge of the condensed water 20 in the accommodating space 11. When the vehicle 1 is in the indoor state, the controller 40 controls the control valve 30 to block the drain port 12 to prevent the condensed water 20 from being discharged into the indoor environment, thereby alleviating the risk of the indoor environment being polluted due to the discharge of the condensed water 20 into the indoor environment, making the vehicle liquid discharge device 2 more green and environmentally friendly.

[0043] In some embodiments, the vehicle liquid discharge device 2 further includes a water pump 50 and an atomizer 60, which are connected to the housing 10 in sequence, and the water pump 50 is used to pump the condensed water 20 in the housing 10 to the atomizer 60; when the vehicle 1 is in an indoor state, the controller 40 is used to control the water pump 50 to be in a shutdown state in response to the liquid level of the condensed water 20 in the receiving space 11 being less than or equal to a first preset height, and the controller 40 is used to control the water pump 50 to start in response to the liquid level being greater than or equal to a second preset height, so that the water pump 50 pumps the condensed water 20 in the housing 10 to the atomizer 60 and atomizes and discharges it; wherein the second preset height is greater than the first preset height. The water pump 50 is connected to the housing 10, and the atomizer 60 is connected to the water pump 50, and the water pump 50 can pump the condensed water 20 to the atomizer 60. When the vehicle 1 is in an indoor state, the controller 40 controls the control valve 30 to block the drain port 12. Further, in response to the liquid level of the condensed water 20 in the receiving space 11 being less than or equal to the first preset height, the controller 40 controls the water pump 50 to be in a shutdown state. The first preset height may be a lower liquid level in the receiving space 11, such as the lowest water level in the receiving space 11. It can be understood that in this state, the control valve 30 blocks the drain port 12, and the water pump 50 is shut down, and the condensed water 20 in the receiving space 11 cannot be discharged, so that the condensed water 20 is stored in the receiving space 11. In response to the liquid level being greater than or equal to the second preset height, the controller 40 controls the water pump 50 to start, so that the water pump 50 pumps the condensed water 20 in the housing 10 to the atomizer 60, and atomizes and discharges it. The second preset height can be a higher liquid level in the accommodation space 11, such as the highest water level in the accommodation space 11. It is understandable that in this state, the control valve 30 blocks the drain port 12, and the liquid level in the accommodation space 11 is at a higher level. The condensed water 20 can be pumped to the atomizer 60 by the water pump 50 and discharged in atomized form. It should be noted that the condensed water 20 has a lower temperature, and can be cooled by atomizing and spraying the condensed water 20 to the equipment to be cooled. In some application scenarios, the atomizer 60 sprays the condensed water 20 after atomizing the condensed water 20 to the surface of the condenser, thereby fully utilizing the low temperature of the condensed water 20 to cool the condenser, thereby improving the utilization rate of the condensed water 20. As a result, it is convenient to store the condensed water 20 when there is less condensed water 20, and to discharge the condensed water 20 in time when the accommodation space 11 is insufficient, thereby alleviating the risk of overflow of the condensed water 20 due to insufficient accommodation space 11. At the same time, the low temperature characteristics of the condensed water 20 can be fully utilized, thereby improving the utilization rate of the condensed water 20, and further improving the environmental protection of the vehicle liquid discharge device 2.

[0044] In some embodiments, when the vehicle 1 is in an indoor state, the controller 40 is further used to control the water pump 50 to be in a shutdown state in response to the liquid level being greater than the first preset height and less than the second preset height, and the liquid level is positively increasing within a preset time period; and to control the water pump 50 to be in an open state in response to the liquid level being greater than the first preset height and less than the second preset height, and the liquid level is negatively increasing within a preset time period. The preset time period may refer to a time period before the moment when the state that the liquid level is greater than the first preset height and less than the second preset height is obtained. Exemplarily, the liquid level is greater than the first preset height and less than the second preset height, and the liquid level is positively increasing from less than the first preset height to greater than the first preset height and less than the second preset height within the preset time period. In this state, the controller 40 controls the water pump 50 to be in a shutdown state, so as to facilitate the storage of the condensed water 20 in the receiving space 11. Exemplarily, the liquid level is greater than the first preset height and less than the second preset height, and the liquid level negatively increases from greater than the second preset height to greater than the first preset height and less than the second preset height within the preset time period. In this state, the controller 40 controls the water pump 50 to be in the on state, so that the condensed water 20 in the receiving space 11 is conveniently discharged by atomization through the atomizer 60. As a result, it is convenient to store the condensed water 20 when there is less condensed water 20, and to discharge the condensed water 20 in time when the receiving space 11 is insufficient, thereby alleviating the risk of overflow of the condensed water 20 due to insufficient receiving space 11, and at the same time, the low temperature characteristics of the condensed water 20 can be fully utilized, thereby improving the utilization rate of the condensed water 20 and further improving the environmental protection of the vehicle liquid discharge device 2.

[0045] In some embodiments, the vehicle liquid discharge device 2 further includes a liquid level detection component 70, which is disposed in the receiving space 11 and is used to obtain the liquid level. Thus, the liquid level information of the condensed water 20 in the receiving space 11 can be obtained through the liquid level detection component 70, so that the controller 40 can control the water pump 50 and the atomizer 60 according to the liquid level.

[0046] In some embodiments, the liquid level detection assembly 70 includes a liquid level sensor 71 and a floating plate 72. The liquid level sensor 71 is disposed at one end of the receiving space 11 away from the drain port 12. The floating plate 72 is disposed in the receiving space 11 and can float on the liquid surface of the condensed water 20. The liquid level sensor 71 is configured to obtain the liquid level of the condensed water 20 according to the distance between the liquid level sensor 71 and the floating plate 72. It can be understood that the height of the floating plate 72 can change with the change of the liquid level of the condensed water 20, and the liquid level sensor 71 can obtain the liquid level of the condensed water 20 according to the distance between the floating plate 72 and the liquid level sensor 71. Exemplarily, the liquid level sensor 71 is fixedly disposed at the top of the receiving space 11, and continuously or intermittently sends a detection signal to the floating plate 72, and receives a feedback signal fed back by the floating plate 72 to obtain the distance between the floating plate 72 and the liquid level sensor 71, and then calculates the liquid level of the condensed water 20 according to the specific height of the liquid level sensor 71 in the receiving space 11. Thus, the liquid level of the condensed water 20 can be obtained by the liquid level sensor 71 and the floating plate 72, which improves the accuracy of obtaining the liquid level and reduces the risk of the controller 40 making an erroneous control according to the inaccurate liquid level. It should be noted that the shape of the floating plate 72 can be the same as the shape of the cross section of the receiving space 11, and the area of ​​the floating plate 72 should be smaller than the area of ​​the cross section of the receiving space 11, so as to reduce the risk of the floating plate 72 getting stuck with the inner surface of the shell 10 during the process of changing the height with the change of the liquid level of the condensed water 20. For example, the inner surface of the shell 10 can form a limiting column protruding toward the receiving space 11, and the limiting column extends in the direction of gravity, and the floating plate 72 can be provided with a limiting groove corresponding to the limiting column, and at least part of the limiting column is located in the limiting groove, so that the floating plate 72 moves in the direction of gravity as the liquid level of the condensed water 20 changes through the cooperation of the limiting groove and the limiting column.

[0047] In some embodiments, the floating plate 72 is provided with a plurality of through holes 721 penetrating the opposite surfaces of the floating plate 72 to allow at least part of the condensed water 20 to enter or exit the through holes 721. It should be noted that the plurality of through holes 721 may be evenly distributed on the floating plate 72. For example, the plurality of through holes 721 may be arranged in an array on the floating plate 72. For example, the plurality of through holes 721 may be arranged in a matrix array, a circular array, a honeycomb array, a spiral array, etc. It is understandable that the vehicle 1 is prone to bumps or tilts relative to the direction of gravity during movement and in a parked state. In these cases, the condensed water 20 in the receiving space 11 is prone to fluctuations, and the liquid level of the condensed water 20 is prone to fluctuations or tilts. It should be noted that the through hole 721 on the floating plate 72 can facilitate the condensed water 20 to enter the through hole 721 when fluctuating, or move between the two opposite surfaces of the floating plate 72 through the through hole 721, which helps the floating plate 72 to fit the liquid surface of the condensed water 20, thereby improving the stability of the floating plate 72 on the fluctuating liquid surface, and alleviating the risk of decreased measurement accuracy of the floating plate 72 on the fluctuating liquid surface, causing the controller 40 to incorrectly control the water pump 50.

[0048] In some embodiments, the vehicle liquid discharge device 2 further includes a filter 80, which is disposed between the atomizer 60 and the water pump 50, and is connected to the water pump 50 and the atomizer 60, respectively, to filter the condensed water 20 pumped by the water pump 50. The filter 80 can filter impurities in the condensed water 20. Thus, the risk of excessive impurities in the condensed water 20 clogging the capillary in the atomizer 60 is alleviated, and the reliability of the vehicle liquid discharge device 2 is improved.

[0049] Please combine Fig. 9 , Fig. 9 It is a flow chart of a vehicle liquid discharge method according to one or more embodiments of the present application.

[0050] In order to solve the above problems, the present application also provides a vehicle 1 liquid discharge method, which is applied to the above vehicle liquid discharge device 2, and the vehicle 1 liquid discharge method includes:

[0051] Step S11: In response to the vehicle being in an indoor state, controlling the control valve to block the drain outlet.

[0052] Specifically, in response to the vehicle 1 being in an indoor state, the controller 40 controls the control valve 30 to block the drain port 12 to prevent the condensed water 20 from being discharged, thereby alleviating the risk of the condensed water 20 being discharged into the indoor environment and causing the indoor environment to be polluted, making the vehicle liquid discharge device 2 more environmentally friendly. In some application scenarios, before step S11, the location information of the vehicle 1 is also obtained, and it is determined whether the vehicle 1 is in an indoor state based on the location information. Among them, illustratively, the location information of the vehicle 1 can be obtained through the vehicle 1 positioning device, such as GPS, and it is determined whether the vehicle 1 is located inside the building based on the location information. If the vehicle 1 is located inside the building, it is determined that the vehicle 1 is in an indoor state.

[0053] Step S12: In response to the vehicle being in an outdoor state, controlling the control valve to open at least part of the drain outlet.

[0054] Specifically, in response to the vehicle 1 being in an outdoor state, the controller 40 controls the control valve 30 to open at least part of the drain port 12 so as to discharge the condensed water 20 to the outdoor environment. In some application scenarios, before step S12, the location information of the vehicle 1 is also obtained, and whether the vehicle 1 is in an outdoor state is determined according to the location information. Exemplarily, the location information of the vehicle 1 can be obtained through a positioning device of the vehicle 1, such as a GPS, and whether the vehicle 1 is located outside the building can be determined according to the location information. If the vehicle 1 is located outside the building, it is determined that the vehicle 1 is in an outdoor state.

[0055] In some embodiments, the vehicle liquid discharge device 2 also includes a water pump 50 and an atomizer 60, which are connected to the shell 10 in sequence, and the water pump 50 is used to pump the condensed water 20 in the shell 10 to the atomizer 60. Step S11 also includes: in response to the liquid level of the condensed water 20 in the accommodating space 11 being less than or equal to a first preset height, controlling the water pump 50 to be in a shutdown state; in response to the liquid level being greater than or equal to a second preset height, controlling the water pump 50 to turn on; wherein the second preset height is greater than the first preset height.

[0056] In response to the liquid level of the condensed water 20 in the receiving space 11 being less than or equal to the first preset height, the water pump 50 is controlled to be in a shutdown state. The first preset height may be a lower liquid level in the receiving space 11, such as the lowest water level in the receiving space 11. It is understood that in this state, the control valve 30 blocks the drain port 12, and the water pump 50 is shut down, and the condensed water 20 in the receiving space 11 cannot be discharged, so that the condensed water 20 is stored in the receiving space 11. In response to the liquid level being greater than or equal to the second preset height, the water pump 50 is controlled to be turned on, so that the water pump 50 pumps the condensed water 20 in the housing 10 to the atomizer 60, and atomizes and discharges it. The second preset height can be a higher liquid level in the accommodation space 11, such as the highest water level in the accommodation space 11. It is understandable that in this state, the control valve 30 blocks the drain port 12, and the liquid level in the accommodation space 11 is at a higher level. The condensed water 20 can be pumped to the atomizer 60 by the water pump 50 and discharged in atomized form. It should be noted that the condensed water 20 has a lower temperature, and can be cooled by atomizing and spraying the condensed water 20 to the equipment to be cooled. In some application scenarios, the atomizer 60 sprays the condensed water 20 after atomizing the condensed water 20 to the surface of the condenser, thereby fully utilizing the low temperature of the condensed water 20 to cool the condenser, thereby improving the utilization rate of the condensed water 20. As a result, it is convenient to store the condensed water 20 when there is less condensed water 20, and to discharge the condensed water 20 in time when the accommodation space 11 is insufficient, thereby alleviating the risk of overflow of the condensed water 20 due to insufficient accommodation space 11. At the same time, the low temperature characteristics of the condensed water 20 can be fully utilized, thereby improving the utilization rate of the condensed water 20, and further improving the environmental protection of the vehicle liquid discharge device 2.

[0057] In summary, the vehicle liquid discharge device 2 provided by the present application includes a housing 10, a control valve 30 and a controller 40. The housing 10 has a receiving space 11 and a drain port 12. The receiving space 11 is used to receive condensed water 20, and the drain port 12 connects the receiving space 11 with the outside. The control valve 30 is arranged at the drain port 12. The controller 40 is used to control the control valve 30 to block the drain port 12 in response to the vehicle 1 being in an indoor state, and the controller 40 is used to control the control valve 30 to open at least part of the drain port 12 in response to the vehicle 1 being in an outdoor state. Through the above-mentioned embodiment, when the vehicle 1 is in an outdoor state, the controller 40 controls the control valve 30 to open at least part of the drain port 12, so as to facilitate the discharge of the condensed water 20 in the receiving space 11. When the vehicle 1 is in an indoor state, the controller 40 controls the control valve 30 to block the drain port 12 to prevent the condensed water 20 from being discharged into the indoor environment, thereby alleviating the risk of the indoor environment being polluted by the condensed water 20 being discharged into the indoor environment, making the vehicle liquid discharge device 2 more green and environmentally friendly.
