技术领域technical field
本申请涉及空调器技术领域，尤其涉及一种空调柜机及其自清扫控制方法。The present application relates to the technical field of air conditioners, in particular to an air conditioner cabinet and a self-cleaning control method thereof.
背景技术Background technique
空调器是一种用于向封闭的房间、空间或区域提供经过处理后的空气的空气调节电器。An air conditioner is an air conditioning appliance used to supply conditioned air to an enclosed room, space or area.
现有的空调柜机在长期运行时，蒸发器上会不可避免地沉积大量的灰尘、毛绒等附着物，这些附着物如果不及时清理，会影响到空调的制冷与制热效果，甚至影响到空调出风的清洁性，危害到家居人员的身体健康。然而，由于附着物通常是沿着空调内气流的流动方向逐渐在蒸发器上形成附着，导致附着物难以清理。在实际清理工作中，必须把蒸发器从空调柜机上拆卸下来，这不仅操作繁琐，还易对空调器的性能造成影响。When the existing air-conditioning cabinets are in long-term operation, a large amount of dust, plush and other attachments will inevitably be deposited on the evaporator. If these attachments are not cleaned in time, it will affect the cooling and heating effects of the air conditioner, and even affect the air conditioner. The cleanliness of the air outlet of the air conditioner is harmful to the health of household personnel. However, since the deposits usually gradually form attachments on the evaporator along the flow direction of the airflow in the air conditioner, it is difficult to remove the deposits. In the actual cleaning work, the evaporator must be disassembled from the air conditioner cabinet, which is not only cumbersome to operate, but also easily affects the performance of the air conditioner.

下面结合图1-图8描述本申请的一种空调柜机及其自清扫控制方法。An air conditioner cabinet and its self-cleaning control method of the present application will be described below with reference to FIGS. 1-8 .
如图1至图4所示，本实施例提供一种空调柜机，包括机壳1；机壳1内设有蒸发器2，机壳1的壳壁上设有第一风口3与第二风口4。本实施例所示的空调柜机还包括：多个风机5、多个风道6及出风调控装置；多个风机5一一对应地设于多个风道6内；多个风道6的第一端口朝向蒸发器2的第一侧面，多个风道6的第二端口分别与第二风口4连通；蒸发器2的第二侧面朝向第一风口3；出风调控装置设于第二风口4，出风调控装置具有关闭第二风口4的第一状态与打开所述第二风口4的第二状态。As shown in Figures 1 to 4, this embodiment provides an air conditioner cabinet, including a casing 1; an evaporator 2 is arranged inside the casing 1, and a first tuyere 3 and a second Tuyere 4. The air conditioner cabinet machine shown in this embodiment also includes: a plurality of fans 5, a plurality of air ducts 6 and an air outlet control device; a plurality of fans 5 are arranged in a plurality of air ducts 6 in one-to-one correspondence; The first port of the evaporator faces the first side of the evaporator 2, and the second ports of the plurality of air ducts 6 communicate with the second air port 4 respectively; the second side of the evaporator 2 faces the first air port 3; The second tuyere 4 , the air outlet control device has a first state of closing the second tuyere 4 and a second state of opening the second tuyere 4 .
具体地，本实施例基于对空调柜机的内部结构的优化设计，可在空调柜机正常运行工作时，控制出风调控装置处于第二状态，以打开第二风口4，并控制多个风机5以第一旋向运转，可使得室内空气在依次通过第一风口3与蒸发器2之后，再沿着各个风道6从第二风口4排向室内，以实 现对室内环境的制冷或制热；与此同时，在对空调柜机进行清扫控制时，控制出风调控装置处于第一状态，以关闭第二风口4，可控制多个风机5当中的一部分以第一旋向启动运转，多个风机5当中的另一部分以第二旋向启动运转或处于关机状态，以实现对蒸发器2的自动吹扫。Specifically, this embodiment is based on the optimized design of the internal structure of the air-conditioning cabinet. When the air-conditioning cabinet is operating normally, the air outlet control device can be controlled to be in the second state to open the second air outlet 4 and control multiple fans. 5. Running in the first rotation direction, the indoor air can be discharged into the room from the second air outlet 4 along each air duct 6 after passing through the first air outlet 3 and the evaporator 2 in sequence, so as to realize the cooling or cooling of the indoor environment. At the same time, when controlling the cleaning of the air-conditioning cabinet, the air outlet control device is controlled to be in the first state to close the second air outlet 4, and a part of the plurality of fans 5 can be controlled to start running in the first rotation direction. Another part of the plurality of blowers 5 starts to operate with the second rotation direction or is in a shutdown state, so as to realize automatic purging of the evaporator 2 .
由此可见，本实施例基于对空调柜机内部结构的改进，既确保了对室内环境正常的温度调节功能，又可通过反向吹扫的方式对蒸发器2上的附着物进行自动清理，其操作简单便捷，确保了空调器正常的工作性能。It can be seen that this embodiment is based on the improvement of the internal structure of the air-conditioning cabinet, which not only ensures the normal temperature adjustment function of the indoor environment, but also automatically cleans the attachments on the evaporator 2 by means of reverse blowing. Its operation is simple and convenient, ensuring the normal working performance of the air conditioner.
在此应指出的是，本实施例所示的第一风口3既可设置一个，也可设置多个。在第一风口3设置为一个的情况下，多个风道6的第一端口共同与一个第一风口3的不同区域对应设置。如此，在控制多个风机5当中的一部分以第一旋向启动运转时，可驱动室内的空气通过第一风口3的部分区域进入至机壳1内，并在经过其中一部分风道6的导流后，输送至第二风口4；由于第二风口4关闭，但各个风道6的第二端口彼此连通，则风送气流只能从另一部分风道6流动，并在对蒸发器2进行反向吹扫后，从第一风口3的其它区域排出机壳1。在此过程中，可控制另一部分风道6中的风机5以第二旋向启动运转或处于关机状态。It should be noted here that the first tuyere 3 shown in this embodiment may be provided with one or multiple. In the case that one first tuyere 3 is provided, the first ports of the plurality of air ducts 6 are jointly arranged corresponding to different regions of one first tuyere 3 . In this way, when a part of the plurality of fans 5 is controlled to start running in the first rotation direction, the air in the room can be driven to enter the casing 1 through a part of the first air port 3 , and pass through a part of the air ducts 6 . After the air flow, it is transported to the second tuyere 4; because the second tuyere 4 is closed, but the second ports of each air duct 6 are connected to each other, the air flow can only flow from another part of the air duct 6, and the evaporator 2 After reverse blowing, the casing 1 is discharged from other areas of the first tuyere 3 . During this process, the fan 5 in another part of the air duct 6 can be controlled to start running in the second rotation direction or to be in a shutdown state.
相应地，在第一风口3设置为多个的情况下，多个风道6的第一端口分别与多个第一风口3一一对应设置。如此，在控制多个风机5当中的一部分以第一旋向启动运转时，可使得室内的空气通过其中一部分第一风口3进入至机壳1内，并在经过其中一部分风道6的导流后，输送至第二风口4；由于第二风口4关闭，但各个风道6的第二端口彼此连通，则风送气流只能从另一部分风道6流动，并在对蒸发器2进行反向吹扫后，从其它第一风口3排出机壳1。Correspondingly, when there are multiple first tuyeres 3 , the first ports of the multiple air ducts 6 are set in one-to-one correspondence with the multiple first tuyeres 3 . In this way, when a part of the plurality of fans 5 is controlled to start running in the first rotation direction, the air in the room can enter the casing 1 through a part of the first air outlets 3 , and pass through a part of the air ducts 6 to guide the air. After that, it is transported to the second tuyere 4; because the second tuyere 4 is closed, but the second ports of each air duct 6 are connected to each other, the air flow can only flow from another part of the air duct 6, and the evaporator 2 is reversed. After blowing, the casing 1 is discharged from the other first tuyere 3 .
如图1所示，本实施例所示的机壳1内具体设有两个风道6，两个风道6的第一端口共同朝向蒸发器2的第一侧面，蒸发器2的第二侧面分别朝向两个呈上下分布的第一风口3。如此，室内空气在从设于上端的第一风口3及蒸发器2的上端依次通入至机壳1内时，机壳1内的气流可从蒸发器2的下端反向通过，并从设于下端的第一风口3排出。相应地，室内空气在从设于下端的第一风口3及蒸发器2的下端依次通入至机壳1内时，机壳1内的气流可从蒸发器2的上端反向通过，并从设于上端的第一风口 3排出。As shown in Figure 1, two air ducts 6 are specifically provided in the casing 1 shown in this embodiment, the first ports of the two air ducts 6 face the first side of the evaporator 2 together, and the second side of the evaporator 2 The sides respectively face two first air outlets 3 distributed up and down. In this way, when the indoor air enters the casing 1 sequentially from the first tuyere 3 on the upper end and the upper end of the evaporator 2, the airflow in the casing 1 can reversely pass through the lower end of the evaporator 2, and flow from the device It is discharged from the first tuyere 3 at the lower end. Correspondingly, when the indoor air enters the casing 1 sequentially from the first tuyeres 3 arranged at the lower end and the lower end of the evaporator 2, the airflow in the casing 1 can reversely pass through the upper end of the evaporator 2 and flow from The first tuyere 3 located at the upper end is discharged.
