[0017] The embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present disclosure, but should not be understood as limiting the present disclosure.

[0018] The terms "first" and "second" and the like in the specification, claims, and drawings of the embodiments of the present disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the embodiments of the present disclosure described herein can, for example, be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product, or apparatus comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products, or apparatus.

[0019] With the advancement of science and technology, the requirements for vehicle air conditioners are becoming increasingly stringent. Reducing design costs is a crucial factor in the design process. Conventional vehicle air conditioners require a complete assembly of a blower, evaporator, heater core, air flow selector damper, and air mixing damper to achieve heating, ventilation, and air conditioning functions. This configuration requires a large number of components, resulting in high costs.

[0020] The following specific embodiments describe in detail the technical solutions of the present disclosure and how the technical solutions of the present disclosure solve the above-mentioned technical problems. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. The following embodiments of the present disclosure are described in conjunction with the accompanying drawings.

[0021] Figure 1 This is a schematic diagram of the structure of a vehicle air conditioner provided by an exemplary embodiment of the present disclosure. The device can be applied to electric vehicles, automobiles, and other equipment that can be installed with air conditioners. The vehicle air conditioner includes a housing 1, a blower 2, an evaporator 3, and a heater core 4.

[0022] Wherein, the box body 1 is provided with an air inlet and an air outlet;

[0023] The heater core 4 is arranged on a side of the box body close to the air outlet, and the evaporator 3 is arranged on a side of the box body close to the air inlet; the blower 2 is arranged on a side of the box body close to the air inlet and away from the evaporator 3, and is used to extract air outside the box body 1 and transport it into the box body, so that the air passes through the evaporator 3 and the heater core 4 in sequence.

[0024] In this embodiment, the blower realizes the function of circulating the air inside the vehicle or sucking the air outside the vehicle into the vehicle.

[0025] In this embodiment, the evaporator can achieve heat exchange with the air sucked in by the blower.

[0026] In this embodiment, the heater core may heat the air flowing through the heater core, causing the temperature of the air to increase.

[0027] Specifically, in the existing vehicle air conditioner, an air mixing damper is provided above the heater core 4 in the box 1 to regulate the ratio of the air in the box 1 passing through the heater core. This design scheme will increase the power consumption of the heater core and increase the design cost of the vehicle air conditioner. Therefore, in the present disclosure, Figure 1 As shown, the heater core 4 is arranged on the side of the box body 1 close to the air outlet, and the air flowing through the side close to the air outlet all passes through the heater core, without the need for an air mixing damper. This arrangement will reduce the cost of designing the vehicle air conditioner.

[0028] In some embodiments, an air intake damper is provided at the air inlet of the box body, and the air intake damper is used to select the air intake channel. Figure 1 As shown, the air intake damper 5 is set at the air inlet. By adjusting the switch position of the air intake damper, different air intake channels can be selected, that is, the air outside the box or the internal circulation air. Among them, the air outside the box refers to the air outside the vehicle, and the internal circulation air refers to the air inside the vehicle.

[0029] In another embodiment, the air intake damper 5 can select all air intake channels at the air inlet at the same time, that is, the air inhaled by the blower is the air outside the box and the circulating air inside the box.

[0030] In some embodiments, the vehicle air conditioner further includes an air outlet device. Figure 2 As shown, the air outlet device 7 is connected to the air outlet and is used to transport the air in the box to the outside of the box.

[0031] Preferably, the air outlet device may be a ventilation duct, or other device capable of conveying air.

[0032] In some embodiments, the vehicle air conditioner further includes: an air flow selection damper.

[0033] Specifically, if Figure 2 As shown, the air flow selection damper 6 is arranged between the air outlet device and the air outlet, and is used to open or close the air outlet device.

[0034] In some embodiments, the air outlet device includes at least one of the following: a side air outlet device, a foot air outlet device, a central air outlet device, and a defrost air outlet device.

[0035] Specifically, combined Figure 2 and Figure 3 As shown, the air outlet device 7 may include a side air outlet device 74 , a foot air outlet device 72 , a central air outlet device 73 and a defrost air outlet device 71 .

[0036] On the basis of the above embodiment, the air flow selection damper is also used to select different air outlet devices. Figure 3 As shown, an air flow selection damper 64 is provided between the side air outlet device 74 and the air outlet, an air flow selection damper 62 is provided between the foot air outlet device 72 and the air outlet, an air flow selection damper 63 is provided between the central air outlet device 73 and the air outlet, and an air flow selection damper 61 is provided between the defrost air outlet device 71 and the air outlet.

[0037] In some embodiments, the number of the air outlet devices and the number of the air flow selection dampers are the same.

[0038] In some embodiments, the vehicle air conditioner further includes a controller connected to the blower, the heater core, and the evaporator, wherein the controller is configured to turn on or off the blower, the heater core, and the evaporator.

[0039] Specifically, the controller may be provided on a vehicle-mounted terminal, and a user may control the vehicle-mounted air conditioner through the vehicle-mounted terminal.

[0040] Among them, the working modes of the vehicle air conditioner include warm air mode, cold air mode, air supply mode and dehumidification mode.

[0041] In some embodiments, when the vehicle air conditioner is in a heating mode, the controller controls the blower and the heater core to turn on, and controls the evaporator to turn off.

[0042] Specifically, combined Figure 3 As shown, when the vehicle air conditioner is in the warm air mode, the controller controls the blower 1 and the heater core 4 to be turned on, and controls the evaporator 2 to be turned off, so that the air inhaled by the blower can be heated by the heater core 4.

[0043] Among them, when the vehicle air conditioner is in different working modes, the switching status of the air flow selection damper corresponding to the air outlet device is different, so in this process, the controller also controls the air flow selection damper 71 in the air flow selection damper to be closed, and the air flow selection damper 72, the air flow selection damper 73, and the air flow selection damper 74 to be opened.

[0044] In some embodiments, when the vehicle air conditioner is in a cooling mode, the controller controls the blower and the evaporator to turn on, and controls the heater core to turn off.

[0045] Specifically, combined Figure 3 As shown, when the vehicle air conditioner is in the cold air mode, the controller controls the evaporator 2 and the blower 1 to be turned on, and controls the heater core 4 to be turned off, so that the air inhaled by the blower can be cooled by the evaporator 2.

[0046] In this process, the controller also controls the airflow selection damper 71 among the airflow selection dampers to be closed, and the airflow selection damper 72, the airflow selection damper 73, and the airflow selection damper 74 to be opened.

[0047] In some embodiments, when the vehicle air conditioner is in air supply mode, the controller controls the blower to turn on, and controls the heater core and the evaporator to turn off.

[0048] Specifically, combined Figure 3As shown, when the vehicle air conditioner is in the air supply mode, the controller controls the blower 1 to turn on, and controls the evaporator 2 and the heater core 4 to turn off, so that the air sucked in by the blower is directly delivered to the vehicle.

[0049] In this process, the controller also controls the airflow selection damper 71 among the airflow selection dampers to be closed, and the airflow selection damper 72, the airflow selection damper 73, and the airflow selection damper 74 to be opened.

[0050] In some embodiments, when the vehicle air conditioner is in a dehumidification mode, the controller controls the blower, the heater core, and the evaporator to turn on.

[0051] Specifically, combined Figure 3 As shown, when the vehicle air conditioner is in the dehumidification mode, the controller controls the evaporator 2, the blower 1 and the heater core 4 to turn on, so that the air sucked in by the blower is dehumidified and then delivered to the vehicle.

[0052] In this process, the controller also controls the airflow selection dampers 71 , 72 , 73 and 74 to be opened.

[0053] In some embodiments, the operating mode of the vehicle air conditioner also includes a defrost mode. When the vehicle air conditioner is in the defrost mode, the controller controls the blower 1 and the heater core 4 to turn on, and controls the evaporator 2 to turn off, so that the air inhaled by the blower is heated and then transported into the vehicle through the air flow selection damper 71 to achieve defrosting.

[0054] In other embodiments, when the vehicle air conditioner is defrosting, the temperature generated by the minimum power provided by the heater core is too high for defrosting in the vehicle. Therefore, when defrosting, the evaporator will be turned on at the same time to first cool the air sucked in by the blower, and then heat the air through the heater core, and finally obtain air at a suitable temperature and transport it to the vehicle for defrosting.

[0055] The technical solution provided by the present disclosure comprises a vehicle air conditioner comprising a housing, a blower, an evaporator, and a heater core. The housing is provided with an air inlet and an air outlet. The heater core is provided on a side of the housing near the air outlet, and the evaporator is provided on a side of the housing near the air inlet. The blower is provided on a side of the housing near the air inlet and away from the evaporator, and is used to draw air from outside the housing and transport it into the housing, so that air passes through the evaporator and the heater core in sequence. By reducing the air mixing damper and damper motor in the original air conditioner, the number of components in the vehicle air conditioner is reduced, lowering the design cost of the vehicle air conditioner. Furthermore, by removing the air damper, the air in the housing can completely pass through the heater core, which can heat the air faster and reduce the power consumption of the heater core.

[0056] Figure 4 A schematic structural diagram of a vehicle is provided as an exemplary embodiment of the present disclosure; wherein the vehicle 12 includes the above exemplary components.

[0057] In some embodiments, the vehicle 12 includes an onboard terminal 11 , and the onboard terminal 11 is connected to the onboard air conditioner 10 .

[0058] In order to better understand this solution, a specific embodiment is provided below to further illustrate the relevant solutions of the vehicle air conditioner. Figure 3 and Figure 4 As shown, the specific process includes the following:

[0059] While the vehicle 12 is in motion, if the user wishes to dehumidify the air inside the vehicle, they only need to select the dehumidification mode for the vehicle air conditioner through the vehicle terminal 11. The controller will then receive the dehumidification command and control the evaporator 2, the blower 1, and the heater core 4 to turn on. This dehumidifies the air drawn in by the blower before delivering it to the vehicle. Furthermore, the controller opens all airflow selector dampers, namely, airflow selector damper 71, airflow selector damper 72, airflow selector damper 73, and airflow selector damper 74. In the present disclosure, this operating mode can significantly reduce the power consumption of the heater core and save costs.
