Referring to fig. 1 to 3, an embodiment of the present disclosure provides a vehicle air conditioner including an evaporator 10, a condenser 20, a first water collecting tank 40, a drain pump 30, and a first water passage pipe 80.

The first water collecting tank 40 is disposed below the evaporator 10 for collecting condensed water generated from the evaporator 10, and a condensed water pipe 50 is communicated with the bottom of the first water collecting tank 40. The first water collecting tank 40 is connected with a water inlet pipe 60 through a condensed water pipe 50, and a water outlet pipe 70 is connected to the water outlet of the drainage pump 30.

The water inlet pipe 60 is provided with a first water inlet 61, and the first water collecting tank 40 is communicated with a condensate pipe 50; the water outlet pipe 70 is provided with a first water outlet 71. One end of the first water pipe 80 is connected to the first water outlet 71, and at least a part of the first water pipe 80 is attached to the surface of the condenser 20.

The vehicle-mounted air conditioner provided by the embodiment of the disclosure is provided with a first water collecting tank 40, and the condensed water generated by the evaporator 10 is recovered and used for cooling the condenser 20. The first water collecting tank 40 is communicated with a condensate pipe 50, and the collected condensate is collected by the first water collecting tank 40 for secondary use. The condensed water pipe 50 is connected to the water inlet pipe 60, and the condensed water is discharged into the drain pump 30 and then discharged from the first water outlet 71 of the drain pipe 70 through the water outlet pipe 70 of the drain pump 30. One end of the first water pipe 80 is connected to the first water outlet 71, and the other end thereof can be directly discharged to the outside.

The first water pipe 80 is spirally fitted over the surface of the condenser 20. In addition, the first water pipe 80 may be entirely attached to the surface of the condenser 20, so that the cooling effect is good, or may be partially attached to the surface of the condenser 20 under the condition that the pipe line is limited.

Optionally, as shown in fig. 4, the vehicle air conditioner further includes a top case 100.

The top case 100 covers the outer surface of the condenser 20, and the first water passage pipe 80 is provided in the top case 100.

In the present embodiment, the first water passage pipe 80 is positioned between the top case 100 and the outer surface of the condenser 20, and the first water passage pipe 80 is mounted to the top case 100. The top case 100 provides a mounting platform for the first water pipe 80, and realizes fixing of the first water pipe 80.

There are various ways to position the first water passage pipe 80 on the top case 100, for example, the top case 100 may be provided with a positioning groove, the inner diameter of the positioning groove is the same as the outer diameter of the first water passage pipe 80, and the first water passage pipe 80 is retained in the positioning groove, thereby fixing the first water passage pipe 80 on the top case 100.

In this embodiment, the first water pipe 80 is attached to the surface of the condenser 20, and the shape of the first water pipe 80 corresponds to the shape of the condenser 20. The surface of the condenser 20 is ensured to be coated as much as possible, so that the contact area of the condenser and the condenser is increased. The larger the contact area, the higher the heat exchange efficiency of the condenser 20.

In this embodiment, the positioning of the first water pipe 80 directly affects the heat exchange efficiency of the condenser 20, and when the first water pipe 80 is attached to the surface of the condenser 20 as much as possible, the condenser 20 can dissipate heat to the maximum extent, thereby improving the heat exchange efficiency.

Optionally, a vent 110 is provided in the top case 100 corresponding to the condenser 20.

In this embodiment, the vent 110 penetrates through the top case 100, and the condenser 20 is communicated with the outside through the vent, so that heat is dissipated through the vent 110, and the heat exchange efficiency of the condenser 20 is further improved. The number of the vent holes 110 may be one or more, and the shape of the vent holes 110 may be any shape.

In the embodiment shown in fig. 4, the ventilation holes 110 are rectangular and are arranged side by side on the top case 100. The larger the number of the vent holes 110 and the larger the area of the through opening, the more the condenser 20 can be directly radiated. However, the number and shape of the ventilation holes 110 are not mandatory.

Optionally, the first water inlet 61 is provided with a first solenoid valve 62 for controlling on/off of the first water inlet 61, and the first water outlet 71 is provided with a second solenoid valve 72 for controlling on/off of the first water outlet 71.

When the condenser 20 needs to exchange heat, the first electromagnetic valve 62 is opened, the first water inlet 61 is communicated, the second electromagnetic valve 72 is opened, the second water inlet 63 is communicated, and the condenser 20 is cooled by using the condensed water generated by the evaporator 10; when the condenser 20 does not need heat exchange, the first electromagnetic valve 62 is closed, the first water inlet 61 is disconnected, the second electromagnetic valve 72 is closed, and the second water inlet 63 is disconnected, so that condensed water generated by the evaporator 10 is prevented from flowing into the first water service pipe 80, and bacterial breeding caused by long-term water accumulation in the first water service pipe 80 is avoided.

Alternatively, the first and second solenoid valves 62, 72 may both be check valves.

In this embodiment, the electromagnetic valve is provided to control the on/off of the water inlet pipe 60 and the water outlet pipe 70 of the drainage pump 30. The first solenoid valve 62 is in one-way communication in a direction from the condensate pipe 50 to the first water inlet 61, and the one-way communication ensures a direction of water flow so that the drain pump 30 can control the condensate water in the first water collecting tank 40 to flow into the drain pump. The second check valve is communicated in one direction from the water inlet pipe 60 to the first water passing pipe 80 so that the drain pump 30 can control the condensed water to be pumped into the first water passing pipe 80.

The cooperation of the first solenoid valve 62 and the second solenoid valve 72 enables the first water collecting tank 40 and the first water pipe 80 to work together, so as to cool the condenser 20 and improve the heat exchange efficiency of the condenser 20.

Alternatively, the first water pipe 80 is spirally disposed on the surface of the condenser 20.

In the present embodiment, the first water passage pipe 80 is provided to extend the length of the first water passage pipe 80 of the condenser 20 so as to contact as much as possible with the surface of the condenser 20.

In the present embodiment, the contact area of the condenser 20 of the first water passage pipe 80 is ensured to be increased, and the heat radiation efficiency of the condenser is also ensured to be increased.

Alternatively, at least a part of the pipes of the first water passage pipe 80 may be metal pipes.

The first water passage pipe 80 may be a metal pipe, and may be a metal, for example, a copper pipe. The first water passage pipe 80 may be made of various metals, for example, an aluminum pipe in part and a copper pipe in part. The first water pipe 80 may also be a metal pipe and a non-metal pipe, for example, a part of the metal pipe is a copper pipe and another part of the non-metal pipe is a plastic pipe.

In this embodiment, the heat conduction and dissipation performance of the metal pipeline is utilized to maximize the cooling effect of the condenser 20. The first water pipe 80 attached to the surface of the condenser 20 is a metal pipe to ensure heat dissipation performance.

Optionally, the first water pipe 80 is made of a non-metal pipe at a portion where the surface of the condenser 20 is not attached, which is beneficial to saving materials and saving cost.

Optionally, as shown in fig. 5, the vehicle air conditioner further includes a detection device 41 and a controller.

A detection device 41 is provided at the first water collection sump 40 for detecting a parameter related to the amount of water in the first water collection sump. The controller is connected with the detection device 41 and the drainage pump 30, and is used for controlling the drainage pump 30 to be started when the parameter is greater than the preset value.

In this embodiment, the detecting device 41 is a water level sensor or a flow sensor, and is used for detecting a water level parameter and a flow parameter in the first water collecting tank 40, respectively. When the vehicle-mounted air conditioner performs refrigeration, when the water level sensor senses that the water level in the first water collecting tank 40 exceeds a preset set water level value or the flow sensor senses that the flow in the first water collecting tank 40 is greater than a set flow value, a control signal is sent to the controller, the controller controls the drainage pump 30 to be opened, under the condition that the first electromagnetic valve 62 and the second electromagnetic valve 72 are arranged, the controller controls the first electromagnetic valve 62 and the second electromagnetic valve 72 to be opened, the condensed water generated by the evaporator 10 flows into the first water passing pipe 80 through the condensed water pipe 50, the water inlet pipe 60, the drainage pump 30 and the water outlet pipe 70 in sequence, and the condenser 20 is cooled through the water inlet pipe 60.

When the water level sensor senses that the water level in the first water collecting tank 40 does not exceed the preset water level value or the flow sensor senses that the flow rate in the first water collecting tank 40 is not greater than the set flow rate value, the controller controls the drainage pump 30 to be closed, and in the case of the first electromagnetic valve 62 and the second electromagnetic valve 72, the controller controls the first electromagnetic valve 62 and the second electromagnetic valve 72 to be closed, so that the condensed water generated from the evaporator 10 cannot flow into the first water passing pipe 80.

The function of the detecting device 41 ensures that the water in the first water collecting tank 40 is not filled and overflowed, and after the water level or the preset flow value is reached, a signal is sent to the controller, and the controller controls the drainage pump 30 to open the first water inlet pipe 60. It is realized that the condensed water in the evaporator 10 can automatically flow out to the first water passing pipe 80 through the drain pump 30, and the heat exchange efficiency of the condenser 20 is improved.

Optionally, as shown in fig. 6, the vehicle air conditioner further includes a temperature sensor 21 and a controller.

The temperature sensor 21 is provided in the condenser 20 and detects the temperature of the condenser. The controller is connected with both the temperature sensor 21 and the drain pump 30, and is used for controlling the drain pump 30 to be started when the temperature is higher than a preset temperature.

In this embodiment, a temperature sensor 21 is provided on the condenser 20, and a preset temperature is set. When the temperature sensor 21 detects that the temperature is higher than the set value, a signal is sent out to enable the controller to control the drain pump 30 to open the water inlet pipe 60, and under the condition that the first electromagnetic valve 62 and the second electromagnetic valve 72 exist, the controller controls the first electromagnetic valve 62 and the second electromagnetic valve 72 to open, so that the condensed water generated by the evaporator 10 flows into the first water pipe 80 through the condensed water pipe 50, the water inlet pipe 60, the drain pump 30 and the water outlet pipe 70 in sequence, and the condenser 20 is cooled. On the contrary, when the temperature sensor 21 detects that the temperature is lower than the set value, the controller controls the drainage pump 30 to close the water inlet pipe 60, and in the case that the first electromagnetic valve 62 and the second electromagnetic valve 72 are provided, the controller controls the first electromagnetic valve 62 and the second electromagnetic valve 72 to close, so that the condensed water generated from the evaporator 10 cannot flow into the first water pipe 80.

The embodiment ensures that when the temperature of the condenser 20 is too high, the drainage pump 30 is automatically controlled to drain water into the first water pipe 80 to cool the condenser 20, and the situation that the temperature of the condenser 20 is too high but no condensed water exists in the first water pipe 80 does not exist.

Optionally, the vehicle air conditioner further includes a second water collection tank 90, a second water passage pipe 91, and a second water outlet 73.

The second water collecting tank 90 is provided under the condenser 20 to collect the condensed water generated from the condenser 20. One end of the second water through pipe 91 is connected with the second water collecting tank 90, the water inlet pipe 60 is further provided with a second water inlet 63, and the other end of the second water through pipe 91 is connected with the second water inlet 63. The water outlet pipe 70 is further provided with a second water outlet 73, and the second water outlet 73 is used for being connected with a humidifier of a vehicle carrying the vehicle-mounted air conditioner and supplying water to the humidifier.

When the vehicle air conditioner heats, the condenser 20 and the evaporator 10 are exchanged in function. At this time, the condenser 20 may generate condensed water, and a second water collecting tank 90 is provided under the condenser 20, and the condensed water in the second water collecting tank 90 flows into the drain pump 30 through the second water inlet 63. The drain pump 30 then discharges the condensed water from the second water outlet 73, and pumps the condensed water into the humidifier through the second water communication pipe 91 for humidifying the vehicle interior.

In this embodiment, the condensed water in the first water passage pipe 80 may directly flow into the second water collection tank 90, as shown in fig. 2, or may be directly discharged to the outside. This illustrates that there are two sources of condensate in the second sump 90. The first source is the condensed water of the first water pipe 80, and the second source is the condensed water generated by the condenser 20 itself directly flowing in when the vehicle air conditioner heats.

In this embodiment, the condensed water discharged from the water outlet pipe 70 may be used to supply water to the humidifier, so that the purpose of the water outlet pipe 70 is increased, and a water source is provided for the humidifier. The scheme makes full use of the condensed water, and ensures the recovery and utilization of the condensed water.

Optionally, the vehicle air conditioner further includes a filter device, and the filter device is disposed in the second water passage pipe 91.

The material of the filtering device is activated carbon or filter cotton, and the filtering is carried out before the second water pipe 91 is connected with the humidifier to ensure the water quality of the vehicle-mounted humidifier.

In the vehicle-mounted air conditioner in the foregoing embodiment, the condensed water in the first water collecting tank 40 and the second water collecting tank 90 can be intelligently controlled in the actual operation process. When the vehicle air conditioner is used for cooling, the condenser 20 is cooled by the condensed water in the first water collecting tank 40 through the first water pipe 80.

The water level sensor or the flow sensor together transmit a signal to the controller to control the drain pump 30 to open the first water inlet pipe 60. The temperature sensor 21 may also transmit a signal to the controller to control the drain pump 30 to open the first water inlet pipe 60.

In this embodiment, the plurality of systems cooperate to cool the condenser 20, thereby ensuring the heat exchange efficiency of the condenser 20. When the vehicle-mounted air conditioner heats, the humidifier is supplied with water through the second water passage pipe 91 by using the condensed water in the second water collection tank 90. The condensed water can be recovered and reused even under the condition of heating of the vehicle-mounted air conditioner.
