Description
Technical Field
[0001] This utility model relates to the field of automotive air conditioning technology, and in particular to an automotive air conditioning unit and an automotive air conditioner. Background Technology
[0002] In a car, the air conditioning unit is a crucial component for cooling, heating, ventilation, and air purification inside the vehicle. It typically offers various modes, including face-blowing, face-to-feet-blowing, feet-blowing, feet-to-defrosting, and defrosting. From the perspectives of comfort and safety, there are corresponding design requirements for the air outlet temperature in different modes and the temperature difference between different air outlets. Specifically, the face-blowing air outlet temperature in a car's air conditioning system is usually required to be lower than the feet-blowing air outlet temperature. This temperature difference ensures comfort while keeping the driver alert and improving driving safety.
[0003] In existing technologies, the temperature difference between the face and feet is typically required to be maintained between 5 and 10°C to ensure the comfort of passengers. This is usually achieved by designing a fixed airflow guiding structure inside the air conditioning unit, behind the heat core, at the junction of hot and cold air (mixing zone). This structure directs some hot air to the face outlet and some cold air to the foot outlet, making the face and foot temperatures similar, with the face temperature slightly lower than the foot temperature. This type of air conditioning unit with an airflow guiding structure requires adjusting the direction and opening of the guiding structure again after adjusting the face or foot temperature, making the adjustment process relatively complex.
[0004] Therefore, there is an urgent need to provide a new type of automotive air conditioning unit and automotive air conditioner to solve the above-mentioned technical problems in the prior art. Utility Model Content

The top of the second part is connected to the first part, the second part is sealed to the connecting part, and the first part is sealed to the outer periphery of the air inlet.
[0014] Optionally, a blowing baffle is provided between the blowing temperature damper and the warm air core, and an airflow baffle is provided between the blowing temperature damper and the foot blowing temperature damper. Part of the airflow flowing through the blowing temperature damper flows above the blowing baffle and directly into the blowing channel, while the other part flows between the blowing baffle and the airflow baffle and flows into the blowing channel from the warm air core.
[0015] Optionally, a foot-blowing baffle is provided between the foot-blowing temperature damper and the warm air core. Part of the airflow flowing through the foot-blowing temperature damper flows to the bottom of the foot-blowing baffle and directly into the foot-blowing channel, while the other part flows between the foot-blowing baffle and the airflow baffle and flows into the foot-blowing channel from the warm air core.

[0017] Beneficial effects:
[0018] This utility model discloses an automotive air conditioning unit containing a heater core and a partition plate. The partition plate is located downstream of the heater core, dividing the downstream area into a face-blowing channel and a foot-blowing channel.

[0030] Please refer to Figure 1 and Figure 2 The automotive air conditioning unit includes an air conditioning unit housing 100, a heater core 200, and a partition plate 300. The air conditioning unit housing 100 has a face temperature damper 101 and a foot temperature damper 102 spaced vertically at the inlet direction. The heater core 200 is located inside the air conditioning unit housing 100 and downstream of the face temperature damper 101 and the foot temperature damper 102. The partition plate 300 is located inside the air conditioning unit housing 100, allowing... The interior of the air conditioning unit housing 100 and the downstream of the heating core 200 are divided into a face blowing channel 112 and a foot blowing channel 111. The partition plate 300 is provided with an air supply port 301, which is positioned directly opposite the heating core 200. The airflow that flows into the heating core 200 after passing through the face blowing temperature damper 101 is heated into face blowing hot air, and part of the face blowing hot air can flow into the foot blowing channel 111 from the air supply port 301.
[0031] In this embodiment, the car air conditioning unit is equipped with a heater core 200 and a partition plate 300. The partition plate 300 is located downstream of the heater core 200, dividing the downstream of the heater core 200 into a face blowing channel 112 and a foot blowing channel 111. The inlet of the air conditioning unit housing 100 is equipped with a face blowing temperature damper 101 and a foot blowing temperature damper 102, which are used for the intake and temperature regulation of the face blowing airflow and foot blowing airflow, respectively. After the face blowing temperature damper 101 takes in the air, it flows through the heater core 200 and is heated into face blowing hot air before flowing downstream. A portion of the face blowing hot air flows into the foot blowing channel 111 through the air supply port 301 and mixes with the foot blowing hot air that has been heated by the heater core 200 after taking in the foot blowing temperature damper 102. This increases the airflow and temperature of the foot blowing hot air, making the foot blowing hot air temperature higher than the face blowing hot air temperature, achieving a face-foot temperature difference, improving the comfort of the driver and passengers. At the same time, its structure is simple and its manufacturing cost is low. This car air conditioning unit can easily and conveniently achieve a temperature difference between the face temperature and the foot temperature, so that the face temperature is slightly lower than the foot temperature, improving the comfort of the driver and passengers.
[0032] Furthermore, the aforementioned partition plate 300 is L-shaped and includes a partition portion 310 and a guide portion 320. The partition portion 310 is disposed perpendicular to the aforementioned warm air core 200, and the guide portion 320 is disposed at the end of the partition portion 310 away from the aforementioned warm air core 200. At least a portion of the guide portion 320 is parallel to the aforementioned warm air core 200, and the guide portion 320 is provided with the aforementioned air inlet 301. In this embodiment, one end of the partition portion 310 is directly connected to the middle part of the warm air core 200, dividing the air outlet of the warm air core 200 into face-blowing hot air and foot-blowing hot air, preventing face-blowing hot air from leaking into the foot-blowing flow channel 111; at the same time, the arrangement of the guide portion 320 can guide the face-blowing hot air upward to the location of the face-blowing damper 103, realizing the guiding function and improving the smoothness of airflow.
[0033] In this embodiment, the foot blowing channel 111 is provided with a foot blowing damper 104, which is used to adjust the opening of the foot blowing channel 111; the face blowing channel 112 is provided with a face blowing damper 103, which is used to adjust the opening of the face blowing channel 112. By providing the foot blowing damper 104 and the face blowing damper 103, the opening of the face blowing channel 112 and the foot blowing channel 111 can be adjusted respectively, changing the airflow of the face blowing hot air and the foot blowing hot air, which is suitable for the usage needs of different drivers and passengers, and further improves the comfort of use.
[0034] It should be noted that when the foot-blowing damper 104 is in the closed state of the foot-blowing channel 111, the foot-blowing damper 104 is sealed to the air supply port 301. When the foot-blowing damper 104 is in the closed state, the foot-blowing channel 111 is in the closed state, and hot air is not needed to blow onto the feet of the driver and passengers. However, the opening of the air supply port 301 would cause hot air to leak from the face to the foot-blowing channel 111. The foot-blowing damper 104 simultaneously blocks the foot-blowing channel 111 and the air supply port 301, which can prevent the leakage of hot air from the face.
[0035] Please continue to refer to this. Figure 1 A blowing baffle 131 is provided between the blowing temperature damper 101 and the warm air core 200, and an airflow baffle 132 is provided between the blowing temperature damper 101 and the foot blowing temperature damper 102. Part of the airflow flowing through the blowing temperature damper 101 flows to the top of the blowing baffle 131 and flows directly into the blowing channel 112, while the other part flows between the blowing baffle 131 and the airflow baffle 132 and flows into the blowing channel 112 from the warm air core 200. An airflow baffle 132 is provided between the face-blowing air damper 103 and the foot-blowing air damper 104 to prevent the mixing of face-blowing air intake and foot-blowing air intake and to prevent airflow leakage. At the same time, the face-blowing baffle 131 can separate the face-blowing air intake into cold air that flows directly to the face-blowing channel 112 and hot air that flows to the face-blowing channel 112 after passing through the warm air core 200. By changing the position and opening of the face-blowing temperature damper 101, the flow rate of hot air and cold air can be changed, thereby changing the temperature of the face-blowing hot air, which is suitable for different usage needs of drivers and passengers.
[0036] Similarly, a foot-blowing baffle 133 is provided between the aforementioned foot-blowing temperature damper 102 and the aforementioned warm air core 200. Part of the airflow flowing through the foot-blowing temperature damper 102 flows to the bottom of the foot-blowing baffle 133 and directly into the foot-blowing flow channel 111, while the other part flows between the foot-blowing baffle 133 and the airflow baffle 132 and flows into the foot-blowing flow channel 111 from the aforementioned warm air core 200. The foot-blowing baffle 133 can separate the foot-blowing air intake into cold air that flows directly into the foot-blowing flow channel 111 and hot air that flows into the foot-blowing flow channel 111 after passing through the warm air core 200. Changing the position and opening of the foot-blowing temperature damper 102 can change the flow rate of hot and cold air, thereby changing the temperature of the foot-blowing hot air, which is suitable for different usage needs of drivers and passengers, and will not be elaborated further here.
[0037] Please refer to Figure 2 and Figure 3The aforementioned foot-blowing damper 104 has a fan-shaped longitudinal section. A sealing gasket 105 is provided on the side wall of the foot-blowing damper 104 near the air supply port 301. The sealing gasket 105 can seal the air supply port 301. The fan-shaped foot-blowing damper 104 can change the opening of the foot-blowing channel 111 as needed, and the sealing gasket 105 on the side wall near the air supply port 301 can seal the air supply port 301, further preventing leakage of hot air from the face. The sealing gasket 105 is made of elastic material, which can increase the contact area and achieve an interference fit through its elasticity, thereby improving the sealing effect.
[0038] Furthermore, the aforementioned partition plate 300 also includes a connecting portion 330. One end of the connecting portion 330 is connected to the junction of the aforementioned partition portion 310 and the aforementioned air guide portion 320, and the other end extends away from the aforementioned warm air core 200. The aforementioned sealing gasket 105 can seal the connection between the aforementioned connecting portion 330 and the aforementioned air inlet 301. The sealing gasket 105 can achieve a double seal on the air inlet 301 by sealing the connection between the air inlet 301 and the connecting portion 330, thereby further improving the sealing effect.
[0039] Optionally, the sealing gasket 105 includes a first part 1051 and a second part 1052 that is attached to one end sidewall of the foot blower 104 near the air supply port 301. The top end of the second part 1052 is connected to the first part 1051. The second part 1052 is sealed to the connecting part 330, and the first part 1051 is sealed to the outer periphery of the air supply port 301. It should be noted that the connecting part 330 originally has a through hole for hot air to be blown from the foot blowing channel 111 to the foot blowing damper 104. The second part 1052 is also sealed to the through hole of the connecting part 330, thus completely blocking the foot blowing channel 111. The first part 1051 completely blocks the outer periphery of the air supply port 301. The sealing gasket 105 configured in this way has a better sealing effect on the air supply port 301 and the foot blowing channel 111, and prevents leakage of the airflow when the foot blowing channel 111 is closed.
[0040] Another objective of this utility model is to provide an automotive air conditioner, which includes an automotive air conditioning unit as described in any of the above embodiments. This automotive air conditioner uses the automotive air conditioning unit described in any of the above embodiments, thereby achieving the beneficial effects of the aforementioned automotive air conditioning unit, which will not be elaborated further here. Specifically, this automotive air conditioner allows a portion of the hot air blowing towards the face to flow into the foot blowing channel 111 through the air inlet 301, mixing with the foot blowing hot air that has been heated by the foot blowing airflow through the warm air core 200 after entering through the foot blowing temperature damper 102. This increases the airflow and temperature of the foot blowing hot air, making the foot blowing hot air temperature higher than the face blowing hot air temperature, achieving a face-to-foot temperature difference, and improving the comfort of the driver and passengers. Simultaneously, its structure is simple and its manufacturing cost is low. This automotive air conditioner can easily and conveniently achieve a temperature difference between the face blowing temperature and the foot blowing temperature, making the face blowing temperature slightly lower than the foot blowing temperature, thus improving the comfort of the driver and passengers.
[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
