Description

Technical Field

[0001] This invention relates to the field of vehicle air conditioning technology, and more particularly to vehicle air conditioning systems. Background Technology

[0002] The function of car air conditioning is to provide a comfortable ambient temperature for passengers. With the booming development of the automotive industry and people's increasing demands for comfort, the air outlet temperature of car air conditioning is becoming more and more personalized and adjustable.

[0003] Existing vehicle air conditioning systems typically use fans to draw in both internal and external air into an air conditioning unit, which contains airflow channels. Cool air cooled by an evaporator-type cooling device and hot air heated by a heater core-type heating device are mixed at a desired ratio inside the air conditioning unit. The mixed air is then blown into the vehicle cabin through ducts from multiple openings within the air conditioning unit (such as face vents and foot vents), thereby regulating the temperature and humidity inside the cabin.

[0004] However, the current method of adjusting the air outlet temperature of automotive air conditioning units mainly relies on adding a fixed airflow guiding structure inside the air conditioning unit to mix the cold and hot air inside and direct it to the required air outlet. However, the temperature difference between different air outlets is fixed at the same temperature damper opening, which cannot meet the personalized requirements of current users for the temperature difference between different air outlets.

[0005] Therefore, vehicle air conditioning is urgently needed to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an in-vehicle air conditioner that solves the problem in related technologies where the temperature difference between different air outlets is fixed at the same vent opening, making it unable to adapt to the personalized temperature adjustment of different air outlets by current users.

[0007] This invention provides a vehicle air conditioner, which includes an air conditioning unit, a cooling unit, and a heating unit. The air conditioning unit includes an air inlet chamber, a mixing chamber, and an air outlet chamber. The air inlet chamber includes a main flow channel, a cold air duct, and a hot air duct. The air outlet of the main flow channel is connected to the air inlets of the cold air duct and the hot air duct, respectively. The air outlets of the cold air duct and the hot air duct are simultaneously connected to the air inlet of the mixing chamber. The air outlet chamber includes multiple air delivery ducts. The air outlet of the mixing chamber is connected to the multiple air delivery ducts. The airflow from the main flow channel enters the cold air duct and the hot air duct through the cooling unit, and the airflow from the hot air duct enters the mixing chamber through the heating unit.

[0008] It also includes a temperature damper assembly and a sliding baffle assembly. At least one of the pipe walls of the air supply duct is opposite to the air outlet of the hot air duct. The pipe wall of the air supply duct opposite to the air outlet of the hot air duct is provided with a guide hole. The sliding baffle assembly can adjust the opening of the guide hole. The temperature damper assembly can adjust the opening of the cold air duct and the hot air duct.

[0009] As a preferred technical solution for vehicle air conditioning, the sliding baffle assembly includes a first baffle and a first driving member. The first driving member drives the first baffle to slide, and the sliding direction of the first baffle intersects with the airflow direction of the guide hole.

[0010] As a preferred technical solution for vehicle air conditioning, the first baffle slides with the inner wall of the air conditioning unit, the first driving component includes a first driving motor and a first drive gear, the first baffle is provided with a first rack along its sliding direction, the first drive gear meshes with the first rack, and the first driving motor drives the first drive gear to rotate.

[0011] As a preferred technical solution for vehicle air conditioning, the sliding direction of the first baffle also intersects with the airflow direction of the air outlet of the mixing chamber, and one end of the first baffle moves away from the guide hole so that the other end of the first baffle moves towards the air outlet of the mixing chamber.

[0012] As a preferred technical solution for vehicle air conditioning, the airflow direction of the air outlet of the mixing chamber is set at an angle to the airflow direction of the guide hole;

[0013] The first baffle is an arc-shaped plate, and the first baffle slides along an arc-shaped trajectory.

[0014] As a preferred technical solution for vehicle air conditioning, the air outlet of the mixing chamber has a first sidewall and a second sidewall; the first sidewall is the pipe wall of the air supply duct with the guide hole, and one end of the first baffle abuts against the first sidewall.

[0015] The sliding baffle assembly further includes a second baffle and a second driving member. One end of the second baffle abuts against the second side wall. The second driving member drives the second baffle to slide within the mixing chamber. The sliding direction of the second baffle intersects with the airflow direction of the air outlet of the mixing chamber. The gap between the first baffle and the second baffle is the opening degree of the air outlet of the mixing chamber.

[0016] As a preferred technical solution for vehicle air conditioning, the second driving component includes a second driving motor and a second drive gear. The second baffle is provided with a second rack along its sliding direction. The second drive gear meshes with the second rack, and the second driving motor drives the second drive gear to rotate.

[0017] As a preferred technical solution for vehicle air conditioning, the cold air duct includes a first cold air duct and a second cold air duct, which are respectively disposed on both sides of the hot air duct.

[0018] As a preferred technical solution for vehicle air conditioning, the air outlet of the main flow channel is divided into a first flow channel, a second flow channel and a third flow channel in sequence. The second flow channel is opposite to the middle position of the hot air duct. The first flow channel is opposite to the first cold air duct and the hot air duct on one side of the second flow channel. The third flow channel is opposite to the second cold air duct and the hot air duct on the other side of the second flow channel.

[0019] The temperature damper assembly includes a first temperature damper, a second temperature damper, and a third temperature damper, which are respectively disposed in the first flow channel, the second flow channel, and the third flow channel.

[0020] As a preferred technical solution for vehicle air conditioning, the first temperature damper can control the opening degree of the first cold air duct and the opening degree of the hot air duct on one side of the second flow channel; the third temperature damper can control the opening degree of the second cold air duct and the opening degree of the hot air duct on the other side of the second flow channel.

[0021] The beneficial effects of this invention are as follows:

[0022] This invention provides a vehicle air conditioner, which includes an air conditioning unit, a cooling unit, a heating unit, a temperature damper assembly, and a sliding baffle assembly. The air conditioning unit includes an air inlet chamber, a mixing chamber, and an air outlet chamber. The air inlet chamber includes a main flow channel, a cold air duct, and a hot air duct. The air outlet of the main flow channel is connected to the air inlets of the cold air duct and the hot air duct, respectively. The air outlets of the cold air duct and the hot air duct are simultaneously connected to the air inlet of the mixing chamber. The air outlet chamber includes multiple air delivery ducts. The air outlet of the mixing chamber is connected to multiple air delivery ducts. The airflow from the main flow channel enters the cold air duct and the hot air duct through the cooling unit. The airflow from the hot air duct enters the mixing chamber through the heating unit. The wall of at least one air delivery duct is opposite to the air outlet of the hot air duct. The wall of the air delivery duct opposite to the air outlet of the hot air duct is provided with a guide hole. The sliding baffle assembly can adjust the opening of the guide hole, and the temperature damper assembly can adjust the opening of the cold air duct and the hot air duct. When the vehicle air conditioner is working, the airflow inside or outside the vehicle cabin first enters the main flow channel. The cooling unit in the main flow channel cools the airflow. The opening of the cold air duct and the hot air duct are controlled by the temperature damper group, thereby controlling the ratio of the airflow entering the cold air duct and the hot air duct. The cooled airflow enters the mixing chamber through the cold air duct according to the preset ratio, and the other part enters the mixing chamber through the hot air duct and is heated by the heating unit. The hot airflow and the cold airflow are mixed in the mixing chamber and then flow out from multiple air ducts. Therefore, the temperature difference between each air duct is a fixed value, making personalized adjustment impossible. To address this, at least one air duct wall is aligned with the outlet of the hot air duct. A guide hole is installed on the wall of the air duct opposite the hot air duct outlet. This allows a portion of the hot air flowing from the hot air duct outlet to directly enter the corresponding air duct through the guide hole. The hot air entering the air duct through the guide hole mixes again with the mixed air flowing into the air duct from the mixing chamber, thus raising the temperature of the airflow in the air duct with the guide hole. The specific amount of hot air entering the corresponding air duct through the guide hole is determined by the sliding baffle assembly. This vehicle air conditioner solves the problem that, under the same temperature damper opening, the temperature difference between different air ducts remains constant, making it unable to adapt to the personalized temperature adjustments required by current users for different air ducts.

[0035] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0036] like Figures 1-4As shown, this embodiment provides a vehicle air conditioner, which includes an air conditioning unit 1, a cooling unit 2, a heating unit 3, a temperature damper assembly, and a sliding baffle assembly. The air conditioning unit 1 includes an air inlet chamber, a mixing chamber 12, and an air outlet chamber. The air inlet chamber includes a main flow channel 111, a cold air duct, and a hot air duct 113. The air outlet of the main flow channel 111 is connected to the air inlet of the cold air duct and the air inlet of the hot air duct 113, respectively. The air outlets of the cold air duct and the hot air duct 113 are simultaneously connected to the air inlet of the mixing chamber 12. The air outlet chamber includes multiple air delivery ducts 131. The air outlet of the mixing chamber 12 is connected to multiple air supply ducts 131. The airflow of the main flow channel 111 enters the cold air duct and the hot air duct 113 through the cooling unit 2. The airflow of the hot air duct 113 enters the mixing chamber 12 through the heating unit 3. The pipe wall of at least one air supply duct 131 is opposite to the air outlet of the hot air duct 113. The pipe wall of the air supply duct 131 opposite to the air outlet of the hot air duct 113 is provided with a guide hole 1211. The sliding baffle group can adjust the opening of the guide hole 1211, and the temperature damper group can adjust the opening of the cold air duct and the hot air duct 113. When the vehicle air conditioner is working, the airflow inside or outside the vehicle cabin first enters the main flow channel 111. The cooling unit 2 in the main flow channel 111 cools the airflow. The opening of the cold air duct and the hot air duct 113 is controlled by the temperature damper group, thereby controlling the ratio of the airflow entering the cold air duct and the hot air duct 113. The cooled airflow enters the mixing chamber 12 through the cold air duct according to the preset ratio, and the other part enters the mixing chamber 12 after being heated by the heating unit 3 through the hot air duct 113. The hot airflow and the cold airflow are mixed in the mixing chamber 12 and then flow out from multiple air supply ducts 131. Therefore, the temperature difference between each air supply duct 131 is a fixed value and cannot be adjusted individually. To address this, the wall of at least one air supply duct 131 is aligned with the outlet of the hot air duct 113. A guide hole 1211 is provided on the wall of the air supply duct 131 that is aligned with the outlet of the hot air duct 113. This allows some of the hot air flowing out of the outlet of the hot air duct 113 to directly enter the corresponding air supply duct 131 through the guide hole 1211. The hot air entering the air supply duct 131 through the guide hole 1211 mixes again with the mixed air flowing into the air supply duct 131 from the mixing chamber 12. This process can heat up the airflow in the air supply duct 131 with the guide hole 1211. The amount of hot air entering the corresponding air supply duct 131 through the guide hole 1211 is determined by the sliding baffle assembly. This vehicle air conditioner solves the problem that the temperature difference between different air ducts 131 remains constant under the same temperature damper opening, and it cannot adapt to the personalized temperature adjustment of different air ducts 131 by current users.

[0037] Optionally, the sliding baffle assembly includes a first baffle 51 and a first driving member. The first driving member drives the first baffle 51 to slide, and the sliding direction of the first baffle 51 intersects with the airflow direction of the guide hole 1211. In this embodiment, the sliding direction of the first baffle 51 intersects with the airflow direction of the guide hole 1211, so the sliding of the first baffle 51 can block the guide hole 1211, thereby adjusting the opening of the guide hole 1211.

[0038] Optionally, the first baffle 51 can be slidably engaged with the inner wall of the air conditioning unit 1. The first driving component includes a first driving motor and a first drive gear 52. A first rack 511 is provided on the first baffle 51 along its sliding direction. The first drive gear 52 meshes with the first rack 511, and the first driving motor drives the first drive gear 52 to rotate. In this embodiment, one of the first baffle 51 and the inner wall of the air conditioning unit 1 is provided with a slide rail, and the other with a slide groove. The slide rail slides within the slide groove. The first driving motor drives the first drive gear 52 to rotate. Since the first rack 511 meshes with the first drive gear 52, the first driving motor drives the first baffle 51 to slide.

[0039] like Figure 3 and Figure 4 As shown, optionally, the sliding direction of the first baffle 51 also intersects with the airflow direction of the air outlet of the mixing chamber 12. One end of the first baffle 51 moves away from the guide hole 1211, so that the other end of the first baffle 51 moves towards the air outlet of the mixing chamber 12. In this embodiment, when the first baffle 51 slides to increase the opening of the guide hole 1211, the other end of the first baffle 51 moves towards the air outlet of the mixing chamber 12 to decrease the opening of the air outlet of the mixing chamber 12.

[0040] Optionally, the airflow direction of the outlet of the mixing chamber 12 is set at an angle to the airflow direction of the guide hole 1211; the first baffle 51 is an arc-shaped plate, and the first baffle 51 slides along an arc-shaped trajectory. In this embodiment, the inner wall of the air conditioning unit 1 is provided with an arc-shaped groove adapted to the first baffle 51, and the first baffle 51 is inserted into the arc-shaped groove and can slide within the arc-shaped groove.

[0041] Optionally, the air outlet of the mixing chamber 12 has a first sidewall 121 and a second sidewall 122 facing each other; the first sidewall 121 is the pipe wall of the air supply duct 131 provided with a guide hole 1211, and one end of the first baffle 51 abuts against the first sidewall 121; the sliding baffle assembly also includes a second baffle and a second driving member, one end of the second baffle abuts against the second sidewall 122, and the second driving member drives the second baffle to slide in the mixing chamber 12, the sliding direction of the second baffle intersects with the airflow direction of the air outlet of the mixing chamber 12, and the gap between the first baffle 51 and the second baffle is the opening degree of the air outlet of the mixing chamber 12. In this embodiment, the sliding direction of the second baffle intersects with the airflow direction at the air outlet of the mixing chamber 12. Therefore, the position of the second baffle allows adjustment of the opening of the air outlet of the mixing chamber 12. When adjusting the opening of the air outlet of the mixing chamber 12, the first baffle 51 and the second baffle can be moved simultaneously to coordinate the adjustment of the opening size of the air outlet of the mixing chamber 12. The first baffle 51 and the second baffle move towards each other, which improves the efficiency of the sliding baffle assembly in adjusting the opening size of the air outlet of the mixing chamber 12. Furthermore, since one end of the first baffle 51 abuts against the first sidewall 121, when one end of the first baffle 51 covers the guide hole 1211, the guide hole 1211 can be sealed.

[0042] Optionally, the second driving component includes a second driving motor and a second drive gear. A second rack is provided on the second baffle along its sliding direction. The second drive gear meshes with the second rack, and the second driving motor drives the second drive gear to rotate. In this embodiment, one of the second baffles and the inner wall of the mixing chamber 12 is provided with a slide rail, and the other with a slide groove. The slide rail slides within the slide groove. The second driving motor drives the second drive gear to rotate. Since the second rack meshes with the second drive gear, the second driving motor drives the second baffle to slide. In other embodiments, the sliding baffle assembly can also be provided with a motor and a transmission component. The motor synchronously drives the first drive gear 52 and the second drive gear to rotate through the transmission component.

[0043] Optionally, the cold air duct includes a first cold air duct 1121 and a second cold air duct 1122, which are respectively disposed on both sides of the hot air duct 113. In this embodiment, after the airflow flows out from the first cold air duct 1121, the second cold air duct 1122 and the hot air duct 113, the cold airflows flowing out from the first cold air duct 1121 and the second cold air duct 1122 are respectively located on both sides of the hot airflow flowing out from the hot air duct 113, which is conducive to the mixing of hot and cold airflows.

[0044] Optionally, the air outlet of the main flow channel 111 is sequentially divided into a first flow channel 1111, a second flow channel 1112, and a third flow channel 1113. The second flow channel 1112 is opposite to the middle position of the hot air duct 113. The first flow channel 1111 is opposite to the first cold air duct 1121 and the hot air duct 113 on one side of the second flow channel 1112. The third flow channel 1113 is opposite to the second cold air duct 1122 and the hot air duct 113 on the other side of the second flow channel 1112. The temperature damper group includes a first temperature damper 41, a second temperature damper 42, and a third temperature damper 43. The first temperature damper 41, the second temperature damper 42, and the third temperature damper 43 are respectively arranged in the first flow channel 1111, the second flow channel 1112, and the third flow channel 1113. In this embodiment, the second temperature damper 42 adjusts the opening of the second flow channel 1112, the first temperature damper 41 adjusts the opening of the first cold air duct 1121 and the hot air duct 113 on one side of the second flow channel 1112, and the third temperature damper 43 adjusts the opening of the first cold air duct 1121 and the hot air duct 113 on the other side of the second flow channel 1112. This arrangement can precisely adjust the airflow of the hot air duct 113, the first cold air duct 1121, and the second cold air duct 1122. The specific structures of the first temperature damper 41, the second temperature damper 42, and the third temperature damper 43 are all prior art and will not be described in detail here.

[0045] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
