Technical Field

[0001] The invention belongs to the technical field of automobile air conditioners and relates to a built-in central automobile air conditioner. Background Art

[0002] The automobile air conditioning system, referred to as HVAC, is used to adjust the temperature, humidity, and air cleanliness in the car and form air circulation, which has an important impact on the comfort of the entire vehicle.

[0003] With the development of automobile air-conditioning technology, there are many types of HVAC assembly structures. Built-in automobile air conditioners are usually arranged under the automobile dashboard, which will occupy part of the space between the driver and the co-driver. This problem is particularly obvious in side-mounted automobile air conditioners that hang the blower on one side of the HVAC assembly. In addition, the condensed water generated by the air-conditioning system is easily retained in the passenger compartment, causing condensation and humidity in the car, affecting the driving experience of the people on the car. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a built-in center-mounted automobile air conditioner, which can effectively reduce the occupied space and prevent condensed water from entering the interior of the vehicle.

[0005] To achieve the above purpose, the technical solution of the present invention is as follows:

[0006] A built-in center-mounted automobile air conditioner comprises a filter assembly, a blower assembly and a mode air distribution assembly which are connected in sequence, wherein the filter assembly and the mode air distribution assembly are arranged at an angle to each other, and the blower assembly is located at the angle between the two, wherein the filter assembly has an air intake chamber, and an inner circulation air outlet and an outer circulation air outlet which are connected to the air intake chamber, and are respectively provided with an inner circulation air door and an outer air air door, and the filter assembly forms an opening at one end close to the blower assembly, an evaporator is installed on the inner side of the opening, and a drainage groove is formed at the bottom of the evaporator, a drainage port which is connected to the drainage groove is provided on the outer wall of the filter assembly, a blower is installed in the blower assembly, and air entering the air intake chamber from the inner circulation air outlet or the outer circulation air outlet can be sucked into the blower assembly, and air is supplied to the vehicle through the mode air distribution assembly, and a water baffle which extends upward and is inclined toward one side of the blower assembly is provided at the bottom of the opening.

[0007] With the above structure, the filter assembly and the mode air distribution assembly form an angle, and the blower is arranged at the middle angle position, which can effectively reduce the space occupied by the automobile air-conditioning assembly. After being assembled on the vehicle, the mode air distribution assembly and the blower assembly are installed under the instrument panel inside the passenger compartment, and the filter assembly is located in the engine compartment. Compared with the traditional built-in automobile air conditioner, the occupied passenger compartment space is reduced; by providing a water baffle at the docking position of the filter assembly and the blower assembly, it can effectively prevent the airflow from bringing the condensed water generated by the evaporator into the interior of the vehicle, which helps to improve the driving experience of the occupants.

[0008] Preferably, the opening of the filter assembly is a planar structure, the blower assembly has a mounting opening suitable for docking with the opening, and a waterproof foam is provided between the mounting opening and the opening.

[0009] Preferably, the outer circulation air outlet is arranged on the bottom surface of the air inlet chamber, and the inner circulation air outlet is located on one side of the air inlet chamber and arranged toward the side where the blower assembly is located. Such a design helps to ensure uniform air intake on the air inlet surface, small wind resistance, uniform wind speed, and combined with the overall layout and structural design, it can greatly improve the performance parameters of the automobile air conditioner.

[0010] Preferably, guide ribs are distributed on the water baffle plate, so as to guide the condensed water blown onto the water baffle plate to flow back into the drainage groove.

[0011] Preferably, support ribs for supporting the evaporator are distributed at the bottom of the drainage trough, each support rib extends along the length of the drainage trough and is provided with staggered notches. This structure can facilitate the installation and positioning of the evaporator and ensure that the drainage performance is not affected.

[0012] Preferably, an air filter is installed between the air intake chamber and the evaporator in the filter assembly, so that the air flow entering through the internal circulation air outlet or the external air outlet can be filtered by the air filter, ensuring fresh air in the vehicle. At the same time, an upwardly extending wind shield is provided between the air filter and the evaporator to prevent the air flow from blowing directly to the drain groove.

[0013] Preferably, the filter assembly is detachably mounted with a cover plate at the outer end of the air inlet chamber away from the evaporator. The cover plate faces the air filter element and is tilted upward. Such a design can facilitate the installation and replacement of the air filter element.

[0014] In order to improve the air-conditioning performance, the blower is preferably a dual-axis blower having outwardly extending flanges on both sides. The blower assembly is provided with slots matching the flanges on both sides inside the mounting port, and is provided with inwardly protruding limit buckles near the mounting port for clamping the blower to achieve rapid installation of the blower and improve the assembly performance of the automobile air conditioner.

[0028] The present invention is further described below in conjunction with embodiments and drawings.

[0029] like Figures 1 to 3The built-in center-mounted automobile air conditioner shown includes a filter assembly 1, a blower assembly 2 and a mode air distribution assembly 3 which are connected in sequence, wherein the filter assembly 1 and the mode air distribution assembly 3 are arranged at an angle to each other, and the blower assembly 2 is located at the angle between the filter assembly 1 and the mode air distribution assembly 3, and the overall structure is a downwardly concave arch structure.

[0030] Among them, the air filter element 7 and the evaporator 4 are installed in the filter assembly 1, the blower 5 is installed in the blower assembly 2, the warm air core 8 is installed in the mode air distribution assembly 3, and a bypass air damper 9 is arranged on one side of the warm air core 8.

[0031] Figures 4 to 7 The specific structure of the filter assembly 1 is shown. As can be seen from the figure, the filter assembly 1 has an air intake chamber 1a inside, and has an inner circulation air outlet 1b and an outer circulation air outlet 1c that pass through the air intake chamber 1a to the outside of the filter assembly 1, which are respectively used to introduce inner circulation air through the vehicle and introduce fresh air from the outside of the vehicle to realize the external circulation function. The inner circulation air outlet 1b and the outer circulation air outlet 1c are respectively provided with an inner circulation damper 1d and an outer air damper 1e to switch between inner and outer circulation when the automobile air conditioner is running.

[0032] As shown in the figure, the external circulation air outlet 1c is located at the bottom surface of the air intake chamber 1a, and the internal circulation air outlet 1b is located outside one side of the air intake chamber 1a and is arranged toward the side where the blower assembly 2 and the mode air distribution assembly 3 are located. After the automobile air conditioner is installed on the vehicle, the internal circulation air outlet 1b can introduce airflow from the passenger compartment.

[0033] An opening 10 is formed at one end of the filter assembly 1 close to the blower assembly 2 . The opening 10 is a planar structure so as to be docked with the blower assembly 2 .

[0034] Combination Figures 1 to 3 It can be seen that the evaporator 4 is installed inside the opening 10 at one end of the filter assembly 1 close to the blower assembly 2, and the air filter element 7 is located on the side of the air inlet chamber 1a close to the evaporator 4, so that the air entering the air inlet chamber 1a from the inner circulation air port 1b and the outer circulation air port 1c needs to pass through the air filter element 7. The filter assembly 1 is mounted with a cover plate 17 in a snap-fit ​​manner at the outer end of the air inlet chamber 1a away from the evaporator 4. The cover plate 17 is arranged toward the air filter element 7 and tilted upward to increase the opening position and facilitate the installation and replacement of the air filter element 7.

[0035] A drainage groove 11 is formed on the bottom wall of the filter assembly 1 at a position corresponding to the bottom of the evaporator 4. A drainage port 12 connected to the drainage groove 11 is provided on the outer wall of the filter assembly 1 at the lowest position corresponding to the drainage groove 11. A plurality of upwardly protruding support ribs 16 are provided at the bottom of the drainage groove 11. The support ribs 16 extend along the length direction of the drainage groove 11. To ensure smooth drainage, each support rib 16 has staggered notches 16a so that the spaces separated by each support rib 16 are interconnected.

[0036] An upwardly extending windshield 15 is provided on the bottom wall of the filter assembly 1 between the evaporator 4 and the air filter element 7. The windshield 15 blocks a partial area of ​​the lower portion of the evaporator 4 to prevent the airflow from blowing directly to the drain groove 11, thereby blowing the condensed water generated by the evaporator 4 into the blower assembly 2 and finally into the vehicle compartment through various air vents, resulting in a "flying water" phenomenon.

[0037] In order to more thoroughly prevent condensed water from entering the vehicle compartment, an upwardly extending water baffle 13 is provided at the bottom of the opening 10 of the filter assembly 1, and the water baffle 13 is located between the evaporator 4 and the blower 5, and is inclined toward the blower 5 to ensure smooth air intake. A plurality of guide ribs 14 are distributed on the surface of the water baffle 13 facing the evaporator 4. The guide ribs 14 protrude upward from the surface of the water baffle 13 and extend downward along the height direction of the water baffle 13, so as to condense the water vapor blown onto the water baffle 13 and guide it downward, so as to flow back to the drainage groove 11 through the gap between the evaporator 4 and the end face of the opening 10.

[0038] Figure 8 It is a schematic diagram of the structure of the blower assembly 2 in this embodiment. The end surface where the blower assembly 2 and the filter assembly 1 are connected forms a mounting opening 21. The mounting opening 21 matches the opening 10 of the filter assembly 1 and is also a planar structure, which is roughly arranged along the longitudinal direction.

[0039] Fig. 9 The specific structure of the blower 5 is shown. As can be seen from the figure, in this embodiment, the blower 5 adopts a double-axis blower form, and the structural design of the blower assembly 2 and the blower 5 can realize the rapid assembly of the blower assembly 2.

[0040] Specifically, the blower 5 has a planar mounting surface 52 , and two arc-shaped convex bumps 53 protruding outward are formed on the back side of the mounting surface 52 for accommodating working parts such as an impeller. The outer ends of both sides of the mounting surface 52 extend outward to form flanges 51 .

[0041] A accommodating chamber 2a for accommodating the blower 5 is formed inside the blower assembly 2. The shape of the accommodating chamber 2a is adapted to the blower 5. The mounting port 21 is communicated with the accommodating chamber 2a. Slots 22 matching the flange 51 are provided on the outer edges of both sides of the accommodating chamber 2a inside the mounting port 21, and a limiting buckle 23 protruding inward is formed near the mounting port 21. When the blower 5 is loaded into the accommodating chamber 2a through the mounting port 21, the flange 51 is embedded in the corresponding slot 22, and the limiting buckle 23 abuts against the outer end surface of the flange 51 on the side close to the mounting port 21, thereby locking the blower 5 in the accommodating chamber 2a.

[0042] Fig.10 The schematic diagram of the structure after the blower assembly 2 and the mode air distribution assembly 3 are assembled. Figure 1 and Figure 2 It can be seen that the mode air distribution assembly 3 is provided with a defrost air outlet 31, a side defrost air outlet 32, a full blowing air outlet 33, a side blowing surface air outlet 34 and a middle blowing surface air outlet 35 on the outer side deviating from the warm air core 8, and a corresponding damper is arranged at the position of each air outlet, wherein the defrost air outlet 31 is arranged toward the side of the filter assembly 1, the opening direction of the middle blowing surface air outlet 35 is opposite to that of the defrost air outlet 31, and is arranged toward the side of the mode air distribution assembly 3 away from the filter assembly 1, and the full blowing air outlet 33 and the side blowing surface air outlet 34 are respectively arranged facing the two sides.

[0043] A driving motor 36 and a mode plate 37 are installed at the upper end of the mode air distribution assembly 3. The driving motor 36 drives the mode plate 37 to rotate through the connecting rod 38, thereby opening or closing each damper to realize the switching of the automobile air conditioner between working modes such as defrosting, surface blowing, and full blowing.

[0044] After the automobile air conditioner of this embodiment is assembled on the vehicle, the blower assembly 2 and the mode air distribution assembly 3 are installed below the dashboard inside the vehicle compartment, while the filter assembly 1 is arranged in the engine compartment. The front panel separating the engine compartment from the vehicle compartment is located at the docking position of the filter assembly 1 and the blower assembly 2, that is, between the opening 10 and the installation opening 21. To ensure the sealing and waterproof performance of the docking position, the circumferential outer edge of the position is coated with waterproof foam 6. In this embodiment, the waterproof foam 6 preferably uses EPDM surface crust foam.

[0045] When the automobile air conditioner is running, the blower 5 works, and the air entering the air intake chamber 1a from the internal circulation air outlet 1b or the external circulation air outlet 1c is sucked into the blower assembly 2 after heat exchange through the air filter 7 and the evaporator 4. After flowing through the warm air core 8 or the bypass damper 9, it is blown into the interior of the vehicle through the corresponding air outlet according to the air outlet mode set by the user. The user can control the opening of the bypass damper 9 as needed to adjust the temperature.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make various similar expressions without violating the purpose and claims of the present invention, and such changes all fall within the scope of protection of the present invention.
