Description

Technical Field

[0001] This utility model relates to the field of air conditioning unit technology, specifically a split-type air conditioning unit. Background Technology

[0002] With the rapid development and popularization of new energy vehicles, especially pure electric vehicles, the powertrain of vehicles has undergone fundamental changes. The engine, which occupies most of the front compartment space in traditional fuel vehicles, has been eliminated and replaced by a more compact electric drive system and related components. This change has created unprecedented and usable spare space in the front compartment of electric vehicles, providing new opportunities for the optimization and redesign of the overall vehicle layout. As a key component to ensure driving and riding comfort, the traditional layout of the automotive air conditioning system is usually a highly integrated air conditioning box assembly, which is installed as a whole under the dashboard in the passenger compartment. In existing integrated automotive air conditioning systems, the blower, which is a noise source, is placed directly below the dashboard in the passenger compartment. This means that the noise generated by the blower when it is running at high speed, along with the vibration noise from the motor and mechanical components, is transmitted directly into the enclosed space of the passenger compartment with almost no attenuation. Although engineers can reduce noise by adding thick sound insulation cotton and designing complex sound-absorbing covers, the noise from the blower when it is working and at the moment of startup will still inevitably enter the cabin, affecting the quietness of the vehicle and the ride quality. Utility Model Content

[0003] The purpose of this utility model is to provide a split-type air conditioning unit to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a split-type air conditioning unit, including an external air conditioning unit installed in the front compartment of a vehicle, a distribution box on one side of the external air conditioning unit, a cooling core installed inside the external air conditioning unit, a heating core installed inside the external air conditioning unit, a blower installed inside the external air conditioning unit, a defrosting vent on the top of the distribution box, a face vent on the top of the distribution box, a first foot vent on one side of the distribution box, a second foot vent on one side of the distribution box, an interior air inlet on one side of the distribution box, an exterior air inlet at the bottom of the distribution box, multiple sets of protective cylinders installed inside the exterior air inlet, a filter plate installed inside the protective cylinder, a scraper rotating on one side of the filter plate, and a fan blade rotating on the other side of the filter plate.

[0009] Preferably, one side of the in-vehicle air intake is connected to the vehicle's passenger compartment, and the bottom of the out-of-vehicle air intake is connected to the outside of the vehicle.

[0010] Preferably, a limiting column runs through the interior of the filter plate, the limiting column rotates inside the filter plate, one end of the limiting column is connected to the scraper, and the other end of the limiting column is connected to the fan blade.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention improves vehicle quietness and driving stability by placing the blower, the biggest noise source inside the external air conditioning unit, outside the cabin, thus avoiding excessive noise affecting the driver.

[0012] This utility model facilitates the routing of vehicle piping and electrical wiring by arranging the cooling and heating cores outside the cabin, and reduces the risk of water leakage inside the cabin by directly draining the condensate from the air conditioning unit outside the cabin. At the same time, it saves passenger cabin space, increases the usable floor space ratio inside the vehicle, and helps car stylists design innovative designs such as floating dashboards and queen-style cars.

[0013] When gas is drawn in through the vehicle's external air intake, the gas is filtered by a filter plate to prevent external impurities from entering through the air intake. At the same time, the gas entering drives the fan blades to rotate, and the rotation of the fan blades drives the scraper to rotate through the limiting column. The rotation of the scraper cleans the impurities attached to the filter plate, preventing impurities from remaining on the filter plate and clogging the filter holes during long-term operation, thus ensuring the normal operation of the device.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1 to 2 This utility model provides a split-type air conditioning unit, including an external air conditioning unit 1 installed in the front compartment of a vehicle. A distribution box 5 is provided on one side of the external air conditioning unit 1. A cooling core 2 and a heating core 3 are installed inside the external air conditioning unit 1. A blower 4 is installed inside the external air conditioning unit 1. A defrost vent 6 and a face vent 7 are also provided on the top of the distribution box 5. A first foot vent 8 and a second foot vent 9 are provided on one side of the distribution box 5. An interior air inlet 10 is provided on one side of the distribution box 5. An exterior air inlet 11 is provided at the bottom of the distribution box 5. Multiple sets of protective cylinders 12 are installed inside the exterior air inlet 11. A filter plate 13 is installed inside the protective cylinder 12. A scraper 15 rotates on one side of the filter plate 13, and a fan blade 16 rotates on the other side of the filter plate 13.

[0018] After the system starts, the blower 4 located at the lower part of the front compartment begins to work, drawing in external air through the external air intake 11. The external air intake 11, designed at the lower front of the vehicle, effectively prevents rainwater from being drawn in, improving the system's waterproof reliability. The drawn-in air first flows through the cooling core 2, where the refrigerant absorbs heat from the air, making the blown-out air cool and dry. When heating is needed, the air flows through the heating core 3, where the cold air is heated into warm air. After temperature regulation, the air reaches the target temperature and is then transported to the target location via the connecting duct. The passenger compartment is designed to regulate its temperature. Placing the blower 4, the largest noise source inside the external air conditioning unit 1, outside the compartment helps to quiet the entire vehicle, improves driving stability, and prevents excessive noise from affecting the driver. At the same time, arranging the cooling core 2 and heating core 3 outside the compartment facilitates the routing of the vehicle's piping and electrical wiring. The condensate from the air conditioning unit is discharged directly outside the compartment, reducing the risk of water leakage inside the compartment. This also saves passenger compartment space, increases the usable floor area ratio, and allows automotive stylists to design innovative designs such as a floating dashboard or a queen's seat.

[0019] Meanwhile, the temperature-controlled air supplied from the front cabin first enters the distribution box 5 located in the passenger compartment. The distribution box 5 is equipped with a special damper mechanism. According to the mode set by the driver, the air conditioning control system precisely controls the opening, closing and angle of these dampers. The distribution box directs the air to the various outlet ducts connected to it. When it is discharged through the defrost vent 6, the air is directed to the windshield to clear fog and frost and ensure the driver's visibility. When it is discharged through the face vent 7, the air is directed to the passenger's face and upper body to provide direct comfort. When it is discharged through the first foot vent 8 and the second foot vent 9, the warm air is directed to the passenger's feet to improve driving comfort.

[0020] At the same time, when gas is drawn into the external air intake 11, it is filtered by the filter plate 13 to prevent external impurities from entering through the external air intake 11. When the gas enters, it drives the fan blade 16 to rotate. The rotation of the fan blade 16 drives the scraper 15 to rotate through the limiting column 14. The rotation of the scraper 15 cleans the impurities attached to the filter plate 13, preventing impurities from remaining on the filter plate 13 during long-term operation and clogging the filter holes on the filter plate 13, thereby ensuring the normal operation of the device.

[0021] In an optional embodiment, the cooling core 2 is used to cool the gas, the heating core 3 is used to heat the gas, and the distribution box 5 is installed inside the vehicle's passenger compartment.

[0022] It should be noted that the inhaled air first flows through the cooling core 2. The refrigerant in the cooling core 2 absorbs the heat of the air, making the blown air cool and dry. When heating is required, the air will flow through the heating core 3, and the cold air will be heated into warm air. After the temperature regulation treatment, the air has the target temperature and is delivered to the crew cabin through the connecting air duct, thereby realizing the temperature regulation of the crew cabin.

[0023] In an optional embodiment, blower 4 is used to deliver gas, and blower 4 is installed at the lower front part of the vehicle's front compartment.

[0024] It should be noted that when blower 4 starts working, it draws in external air through the external air intake 11.

[0025] In an optional embodiment, one side of the external air conditioning unit 1 is connected to the distribution box 5, and the defrost vent 6, the face vent 7, the first foot vent 8, and the second foot vent 9 are all used to spray gas.

[0026] It should be noted that the temperature-controlled air delivered from the front cabin first enters the distribution box 5 located in the crew compartment. The distribution box 5 is equipped with a special damper mechanism. According to the mode set by the pilot, the air conditioning control system precisely controls the opening, closing and angle of these dampers, and the distribution box directs the air to the various outlet ducts connected to it.

[0027] In an optional embodiment, the defrost vent 6, the face vent 7, the first foot vent 8, and the second foot vent 9 are all connected to the instrument panel duct in the passenger compartment.

[0028] It should be noted that when air is discharged through defrost vent 6, it is directed to the windshield to clear fog and frost and ensure driving visibility. When air is discharged through face vent 7, it is directed to the face and upper body of the occupants to provide direct comfort. When air is discharged through the first foot vent 8 and the second foot vent 9, it is directed to the feet of the occupants to improve driving comfort.

[0029] In one optional embodiment, the interior air intake 10 is connected to the vehicle passenger compartment on one side, and the exterior air intake 11 is connected to the outside of the vehicle at its bottom.

[0030] It should be noted that by designing the external air intake 11 at the lower front of the vehicle, rainwater above can be effectively prevented from being sucked in, thus improving the waterproof reliability of the system.

[0031] In an optional embodiment, a limiting post 14 extends through the interior of the filter plate 13. The limiting post 14 rotates inside the filter plate 13. One end of the limiting post 14 is connected to the scraper 15, and the other end of the limiting post 14 is connected to the fan blade 16.

[0032] It should be noted that when gas is drawn into the external air intake 11, it is filtered by the filter plate 13 to prevent external impurities from entering through the external air intake 11. At the same time, the gas pushes the fan blade 16 to rotate. The rotation of the fan blade 16 drives the scraper 15 to rotate through the limiting column 14. The rotation of the scraper 15 cleans the impurities attached to the filter plate 13, preventing impurities from remaining on the filter plate 13 during long-term operation and clogging the filter holes on the filter plate 13, thereby ensuring the normal operation of the device.

[0033] Working principle: After the system is started, the blower 4 located at the lower part of the front compartment starts to work, and draws in external air through the external air intake 11. The drawn-in air first flows through the cooling core 2, where the refrigerant absorbs the heat of the air. When heating is required, the air will flow through the heating core 3, where the cold air is heated into warm air. After temperature regulation, the air is delivered to the passenger compartment through the connecting air duct.

[0034] Meanwhile, the temperature-controlled air delivered from the front cabin first enters the distribution box 5 located in the crew compartment. The distribution box 5 is equipped with a special damper mechanism. According to the mode set by the driver, the air conditioning control system precisely controls the opening, closing and angle of these dampers, and the distribution box directs the air to the various outlet ducts connected to it.

[0035] When gas is drawn into the air intake 11 outside the vehicle, it is filtered by the filter plate 13. At the same time, the gas pushes the fan blade 16 to rotate. The rotation of the fan blade 16 drives the scraper 15 to rotate through the limiting column 14. The rotation of the scraper 15 cleans the impurities attached to the filter plate 13.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
