[0004] 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 that regulates the temperature and humidity in the vehicle cabin, car air conditioning is used to provide passengers with a comfortable driving environment and is an essential part of the car.

[0005] The volute of a car air conditioner collects condensed water during operation. Currently, to ensure the timely removal of condensed water from the volute, a drain port directly connected to the outside world is provided. When the car air conditioner is running, condensed water is discharged from the volute through the drain port. Simultaneously, outside air can also enter the volute through the drain port. When the hot outside air comes into contact with the cold air inside the volute, condensation easily drifts from the return air vent into the vehicle interior, affecting the user experience.

[0006] Accordingly, the art requires a new volute and vehicle air conditioner to solve the above problems.

[0007] Utility Model Content

[0008] The present invention aims to solve the above-mentioned technical problem, namely, to solve the problem that when condensed water is discharged from the inside of the volute to the outside of the volute through the drain port, outside air can enter the volute through the drain port. To this end, the present invention provides a volute. The volute includes:

[0009] base plate;

[0010] The drainage part is arranged on the bottom plate, and the drainage part is provided with a connected water inlet and a drainage outlet. The drainage part includes a first water trap body and a second water trap body.

One end of the first water trap body is connected to the bottom plate, and the first water trap body is provided with a water storage space. One end of the second water trap body is connected to the bottom plate, and the other end extends below the highest liquid level of the water storage space.

[0011] In a specific embodiment of the volute, the first trap body includes a first curved portion and a second curved portion connected to each other, the first curved portion is connected to the bottom plate, and the water storage space is formed between the first curved portion and the second curved portion.

[0012] In a specific embodiment of the volute, the first water trap body further includes a first straight portion, the first curved portion and the second curved portion are respectively connected to the first straight portion, and the water storage space is formed between the first curved portion, the first straight portion and the second curved portion.

[0013] In a specific embodiment of the volute, the second trap body includes a third curved portion and a fourth curved portion connected to each other, the fourth curved portion is connected to the bottom plate, and the third curved portion is spaced apart from the first trap body and is located above the first straight portion.

[0014] In a specific embodiment of the volute, the second trap body further includes a second straight portion, the third curved portion and the fourth curved portion are respectively connected to the second straight portion, and the second straight portion is spaced apart from the second curved portion and is located above the second curved portion.

[0015] In a specific embodiment of the volute, along the axial direction of the water inlet, an upper end surface of the second curved portion is higher than a lower end surface of the third curved portion.

[0016] In a specific embodiment of the volute, the first curved portion has a first inclined surface at one end close to the bottom plate, the first inclined surface is inclined toward the third curved portion, the third curved portion has a second inclined surface at one end away from the second curved portion, and the second inclined surface is inclined toward the first curved portion.

[0017] In a specific embodiment of the volute, the water inlet and the outlet are both in a straight line shape.

[0018] In a specific embodiment of the volute, the bottom plate is provided with two drainage portions, and the two drainage portions are symmetrically distributed.

[0019] The utility model also provides a vehicle-mounted air conditioner, which includes the above-mentioned volute.

[0020] The beneficial effects of the volute and vehicle air conditioner provided by the utility model are:

[0021] The volute collects condensed water generated during vehicle air conditioning operation and also acts as a waterproof barrier, preventing it from entering the vehicle interior or specific areas, thereby protecting the vehicle's electrical equipment, internal structures, and other sensitive components from water damage. A drainage system located on the floor drains condensed water generated during vehicle air conditioning operation, ensuring rapid drainage and preventing corrosion or damage to vehicle components caused by water accumulation.

[0022] The first trap body at the bottom of the drain section and the second trap body at the top of the drain section form a water seal structure inside the drain section. When liquid passes through the curved water seal, the curved shape of the water seal causes a sealed liquid wall to form around the liquid. This liquid wall forms a gas-tight layer on the liquid surface, effectively preventing gas diffusion or penetration. When condensed water is discharged from the volute to the outside through the drain section, it effectively prevents external hot air from entering the volute through the drain section.

[0031] As shown in FIG1 and FIG2, the present invention proposes a volute 300. The volute 300 includes:

[0032] Bottom plate 10;

[0033] 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 outlet 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.

[0034] In this embodiment, the volute 300 collects condensed water generated during vehicle air conditioning operation and also provides a waterproofing function, preventing condensed water from entering the vehicle interior or specific areas, thereby protecting the vehicle's electrical equipment, internal structures, and other sensitive components from water corrosion. A drainage portion 20 provided on the base plate 10 is used to drain condensed water generated during vehicle air conditioning operation, ensuring that this water can be quickly drained, thereby preventing problems such as corrosion or damage to vehicle components caused by water accumulation.

[0035] The first trap body 201 at the bottom of the drain section 20 and the second trap body 202 at the top of the drain section 20 form a water seal structure within the drain section 20. As liquid passes through the curved water seal, the seal's curvature causes a sealed liquid wall to form around the liquid. This liquid wall forms a gas-tight layer on the liquid surface, effectively preventing gas diffusion or penetration. This effectively prevents external hot air from entering the volute 300 through the drain section 20 when condensed water is discharged from the inside of the volute 300 to the outside of the volute 300, thereby improving the overall sealing performance of the volute 300.

[0036] In a possible specific implementation, the bottom plate 10 and the drainage portion 20 of the volute 300 are integrally formed.

[0037] Furthermore, 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 .

[0038] 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.

[0039] 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 water outlet 20b of the drainage unit 20. During operation, the vehicle air conditioner generates condensed water, which, due to gravity, drips onto the bottom plate 10 of the volute 300. The condensed water collected on the bottom plate 10 of the volute 300 flows through the water inlet 20a of the drainage unit 20 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. 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, the condensed water overflows the water storage space and is discharged out of the volute 300 through the water outlet 20b of the drainage unit 20.

[0040] In a possible specific embodiment, the corners of the first curved portion 2011 and the second curved portion 2012 of the first trap body 201 are chamfered, which facilitates smooth demoulding of the first curved portion 2011 and the second curved portion 2012 of the first trap body 201.

[0041] Furthermore, as shown in FIG2 , 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 .

[0042] In this embodiment, the first straight portion 2013 of the first water trap body 201 can increase the distance between the first curved portion 2011 and the second curved portion 2012 of the first water trap body 201, thereby expanding the water storage capacity of the water storage space, which is beneficial to increase the amount of condensed water stored in the water storage space, thereby further improving the water sealing effect.

[0043] Further, as shown in FIG2 , 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 . The third curved portion 2021 is spaced apart from the first water trap body 201 and is located above the first straight portion 2013 .

[0044] 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 external hot air 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.

[0045] In a possible specific embodiment, the corners of the third curved portion 2021 and the fourth curved portion 2022 of the second water trap body 202 can be chamfered to facilitate smooth demolding of the third curved portion 2021 and the fourth curved portion 2022 of the second water trap body 202.

[0046] Furthermore, as shown in FIG2 , 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 .

[0047] 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.

[0048] Furthermore, 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 .

[0049] 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 have a water column of a certain height when it is located 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 preventing external hot air from entering the interior of the volute 300 through the drain port 20b of the drain portion 20.

[0050] Because the upper end surface of the second curved portion 2012 of the first trap body 201 is higher than the lower end surface of the third curved portion 2021 of the second 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 this vertical water column creates a physical barrier for the gas, thereby preventing the gas from continuing to diffuse into the volute 300 through the water column.

[0051] Water also has a high surface tension, meaning that water molecules on the surface attract each other, forming a continuous surface layer. When gas reaches the water's surface, the surface tension prevents the gas from further penetrating into the water, creating an effective barrier to the outside gas. This prevents the gas from diffusing from the water outlet 20b of the volute 300 to the water inlet 20a of the volute 300, and then from diffusing into the interior of the volute 300.

[0052] 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 .

[0053] 3 and 4 , the first curved portion 2011 has a first inclined surface 2014 at one end close to the base plate 10 , and the first inclined surface 2014 is inclined toward the third curved portion 2021 . The third curved portion 2021 has a second inclined surface 2024 at one end away from the second curved portion 2012 , and the second inclined surface 2024 is inclined toward the first curved portion 2011 .

[0054] In this embodiment, this setting method 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 diversion 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.

[0055] In a possible specific implementation, the first inclined surface 2014 and the second inclined surface 2024 are both inclined planes.

[0056] Furthermore, as shown in FIG3 and FIG4 , the water inlet 20a and the water outlet 20b may both be in a straight line shape.

[0057] 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 a timely manner, but also prevent foreign debris from entering the inside of the volute 300 through the drainage portion 20.

[0058] Furthermore, the bottom plate 10 is provided with two drainage portions 20 , and the two drainage portions 20 are symmetrically distributed.

[0059] In this embodiment, the bottom plate 10 is provided with two drainage portions 20, which is beneficial to further increase the speed at which the condensed water is 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 erode the volute 300.

[0060] In a possible specific implementation, the two drainage portions 20 provided on the bottom plate 10 are symmetrically arranged at both ends of the bottom plate 10 of the volute 300 .

[0061] 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.

[0062] The present invention further provides a vehicle-mounted air conditioner, which includes the volute 300 in the above embodiment.

[0063] 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 interior of the volute 300 through the drainage portion 20 and contacting with the cold air inside the volute 300 to generate condensed water, thereby reducing the operating performance of the vehicle air conditioner.

[0064] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
