In recent years, with the continuous improvement of people's living standards and the necessity of travel, cars have become an indispensable means of transportation in people's daily lives. As a system for regulating the temperature and humidity in the car, the car air conditioner is used to provide passengers with a comfortable driving environment and is an indispensable part of the car.

The volute of the car air conditioner can collect condensed water generated when the air conditioner is running. At present, in order to ensure the timely removal of condensed water inside the volute, a drain port directly connected to the outside is provided inside the volute. When the car air conditioner is running, the condensed water generated is discharged from the inside of the volute to the outside of the volute through the drain port. At the same time, the outside air can also enter the volute through the drain port. When the hot air from the outside comes into contact with the cold air inside the volute, it is easy for condensation to float from the return air port to the inside of the car, affecting the user experience.

Accordingly, the art requires a new volute and vehicle air conditioner to solve the above problems.

As shown in FIG. 1 and FIG. 2 , the present invention provides a volute 300. The volute 300 includes:

Bottom plate 10;

The drainage portion 20 is arranged on the bottom plate 10. The drainage portion 20 is provided with a connected water inlet 20a and a drainage port 20b. The drainage portion 20 includes a first water trap body 201 and a second water trap body 202. The first water trap body 201 is located at the bottom of the drainage portion 20, and the second water trap body 202 is located at the top of the drainage portion 20. One end of the first water trap body 201 is connected to the bottom plate 10. The first water trap body 201 is provided with a water storage space. One end of the second water trap body 202 is connected to the bottom plate 10, and the other end extends below the highest liquid level of the water storage space.

In this embodiment, the volute 300 can be used to collect condensed water generated during the operation of the vehicle air conditioner, and also has a waterproof function to prevent condensed water from entering the interior of the vehicle or a specific area, so as to protect the vehicle's electrical equipment, internal structure and other sensitive parts from being corroded by water. The drainage portion 20 provided on the bottom plate 10 is used to drain the condensed water generated during the operation of the vehicle air conditioner to ensure that the water can be quickly drained, thereby preventing the accumulation of water from causing corrosion or damage to vehicle parts.

The first water trap body 201 located at the bottom of the drainage portion 20 and the second water trap body 202 located at the top of the drainage portion 20 form a water trap inside the drainage portion 20. The curved water seal structure is used to seal the liquid. When the liquid passes through the curved water seal, the curved shape of the water seal will cause a sealed liquid wall to form around the liquid. This liquid wall forms a gas sealing layer on the liquid surface, thereby effectively preventing gas diffusion or penetration, so that when the condensed water is discharged from the inside of the volute 300 to the outside of the volute 300 through the drainage portion 20, it can effectively prevent the external hot air from entering the inside of the volute 300 through the drainage portion 20, thereby improving the overall sealing of the volute 300.

In a possible specific implementation, the bottom plate 10 of the volute 300 and the drainage portion 20 are integrally formed.

Further, as shown in FIG. 2 , the first water trap body 201 may include a first curved portion 2011 and a second curved portion 2012 connected to each other, the first curved portion 2011 is connected to the bottom plate 10 , and a water storage space is formed between the first curved portion 2011 and the second curved portion 2012 .

In this embodiment, the bottom plate 10 of the volute 300 and the second curved portion 2012 of the first water trap body 201 are respectively connected to the first curved portion 2011 of the first water trap body 201. This arrangement can form a water storage space between the first curved portion 2011 and the second curved portion 2012 of the first water trap body 201, which is convenient for storing condensed water flowing in from the water inlet 20a of the drainage portion 20.

The water storage space formed between the first curved portion 2011 and the second curved portion 2012 of the first water trap body 201 is connected to the water inlet 20a and the drain outlet 20b of the drainage part 20. Condensed water is generated during the operation of the vehicle air conditioner, and the condensed water drips onto the bottom plate 10 of the volute 300 under the action of gravity. The condensed water gathered on the bottom plate 10 of the volute 300 flows into the water storage space formed between the first curved portion 2011 and the second curved portion 2012 of the first water trap body 201 through the water inlet 20a of the drainage part 20. As the amount of condensed water flowing into the water storage space gradually increases, when the amount of condensed water flowing into the water storage space exceeds the water storage capacity of the water storage space, the condensed water overflows the water storage space and is discharged from the volute 300 through the drain outlet 20b of the drainage part 20.

In a possible specific implementation, the corners of the first curved portion 2011 and the second curved portion 2012 of the first trap body 201 are both rounded, which is beneficial for smooth demoulding of the first curved portion 2011 and the second curved portion 2012 of the first trap body 201.

Further, as shown in FIG. 2 , the first water trap body 201 may further include a first straight portion 2013 , the first curved portion 2011 and the second curved portion 2012 are respectively connected to the first straight portion 2013 , and a water storage space is formed between the first curved portion 2011 , the first straight portion 2013 and the second curved portion 2012 .

In this embodiment, the first straight portion 2013 of the first trap body 201 can be increased. The distance between the first curved portion 2011 and the second curved portion 2012 of the first water trap body 201 is increased, so that the water storage capacity of the water storage space can be expanded, which is beneficial to increase the amount of condensed water stored in the water storage space, so as to further improve the water sealing effect.

Further, as shown in FIG. 2 , the second water trap body 202 may include a third curved portion 2021 and a fourth curved portion 2022 connected to the bottom plate 10 , and the third curved portion 2021 is spaced apart from the first water trap body 201 and is located above the first straight portion 2013 .

In this embodiment, the third curved portion 2021 and the fourth curved portion 2022 of the connected second water trap body 202 can limit the condensed water flowing into the water storage space through the water inlet 20a of the drainage portion 20, so that a water column of a certain height is formed between the second curved portion 2012 of the first water trap body 201 and the third curved portion 2021 of the second water trap body 202, which can isolate the cold air inside the volute 300 from the hot air outside the volute 300, thereby effectively preventing the hot air from the outside from entering the interior of the volute 300 through the drainage portion 20 of the volute 300, thereby improving the overall sealing performance of the volute 300.

In a possible specific implementation, the corners of the third curved portion 2021 and the fourth curved portion 2022 of the second water trap body 202 may be chamfered to facilitate smooth demoulding of the third curved portion 2021 and the fourth curved portion 2022 of the second water trap body 202 .

Further, as shown in FIG. 2 , the second trap body 202 may further include a second straight portion 2023 , the third curved portion 2021 and the fourth curved portion 2022 are respectively connected to the second straight portion 2023 , and the second straight portion 2023 is spaced apart from the second curved portion 2012 and is located above the second curved portion 2012 .

In this embodiment, the second straight portion 2023 of the second water trap body 202 can increase the distance between the second curved portion 2012 of the first water trap body 201 and the third curved portion 2021 of the second water trap body 202, thereby expanding the water storage space between the second curved portion 2012 and the third curved portion 2021, which is beneficial to increase the height of the water column of the condensed water stored in the water storage space, so as to further enhance the water sealing effect.

Further, as shown in FIG. 2 , along the axial direction of the water inlet 20 a , the upper end surface of the second curved portion 2012 is higher than the lower end surface of the third curved portion 2021 .

In this embodiment, along the axial direction of the water inlet 20a, the upper end surface of the second curved portion 2012 is higher than the lower end surface of the third curved portion 2021. This arrangement allows the condensed water to be located at the first curved portion 2012. There is a water column of a certain height between the second curved portion 2012 of the water trap body 201 and the third curved portion 2021 of the second water trap body 202 , thereby preventing external hot air from entering the volute 300 through the drainage port 20 b of the drainage portion 20 .

Since the upper end surface of the second curved portion 2012 of the first water trap body 201 is higher than the lower end surface of the third curved portion 2021 of the second water trap body 202, a vertical water column is formed between the second curved portion 2012 and the third curved portion 2021. The gravity generated by the vertical water column makes the water column form a physical barrier to the gas, thereby preventing the gas from continuing to diffuse toward the inside of the volute 300 through the water column.

Moreover, water has a high surface tension, that is, water molecules on the water surface attract each other to form a continuous surface layer. When the gas reaches the surface of the water, the surface tension of the water prevents the gas from further penetrating into the water, forming an effective barrier to the external gas, thereby preventing the gas from diffusing from the water outlet 20b of the volute 300 to the water inlet 20a of the volute 300, and then diffusing into the interior of the volute 300.

In a possible specific implementation, along the axial direction of the water inlet 20a, the upper end surface of the second curved portion 2012 is 50 mm higher than the lower end surface of the third curved portion 2021 .

Further, as shown in Figures 3 and 4, the end of the first curved portion 2011 close to the base plate 10 has a first inclined surface 2014, the first inclined surface 2014 is inclined toward the third curved portion 2021, and the end of the third curved portion 2021 away from the second curved portion 2012 has a second inclined surface 2024, the second inclined surface 2024 is inclined toward the first curved portion 2011.

In this embodiment, this arrangement can prevent the condensed water generated during the operation of the vehicle air conditioner from accumulating on the bottom plate 10 of the volute 300, and has a certain guiding effect on the condensed water, so that the condensed water can be effectively discharged from the inside of the volute 300 to the outside of the volute 300.

In a possible specific implementation, the first inclined surface 2014 and the second inclined surface 2024 are both inclined planes.

Furthermore, as shown in FIG. 3 and FIG. 4 , the water inlet 20 a and the water outlet 20 b may both be in a straight line shape.

In this embodiment, this arrangement can not only discharge the condensed water generated during the operation of the vehicle air conditioner to the outside of the volute 300 in time, but also prevent foreign debris from entering the inside of the volute 300 through the drainage portion 20.

Furthermore, the bottom plate 10 is provided with two drainage parts 20, and the two drainage parts 20 are It is called distribution.

In this embodiment, the bottom plate 10 is provided with two drainage portions 20, which is beneficial to further increase the speed of condensed water being discharged from the bottom plate 10 of the volute 300 to the outside of the volute 300, thereby preventing the condensed water from being accumulated on the bottom plate 10 of the volute 300 due to failure to be discharged in time, causing the condensed water to overflow or the condensed water to corrode the volute 300.

In a possible specific implementation manner, the two drainage portions 20 provided on the bottom plate 10 are symmetrically arranged at two ends of the bottom plate 10 of the volute 300 .

In a possible specific implementation, the bottom plate 10 is provided with a plurality of drainage portions 20 , and the plurality of drainage portions 20 are symmetrically distributed.

The utility model also provides a vehicle air conditioner, which includes the volute 300 in the above embodiment.

In this embodiment, the drainage portion 20 of the volute 300 is provided with a water seal structure, which can enable the condensed water generated during the operation of the vehicle air conditioner to be discharged to the outside of the volute 300 in a timely manner. At the same time, it can also prevent the external hot air from entering the volute 300 through the drainage portion 20 and contacting the cold air inside the volute 300 to generate condensed water, thereby reducing the operating performance of the vehicle air conditioner.
