一种空调室内机An air conditioner indoor unit

技术领域technical field

本发明涉及空调技术领域，尤其涉及一种空调室内机。The invention relates to the technical field of air conditioners, in particular to an air conditioner indoor unit.

背景技术Background technique

随着人们对空气质量问题越来越重视，空气净化产品越来越受欢迎。现有市场上的空气净化器，将室内空气吸入其内腔，再通过吸附、分解或转化将空气内的污染物处理后重新排入室内，实现空气质量的改善，但空气净化器长期在密闭的室内使用，因不引入新风，导致空气内的含氧量逐渐下降，在室内呼吸时会感觉较闷，因而，需要隔一段时间开窗换气，若室外空气质量较差，未经处理的风直接吹入室内，则会使原本室内的空气再次变差。As people pay more and more attention to air quality issues, air purification products are becoming more and more popular. The existing air purifiers on the market suck indoor air into its inner cavity, and then discharge the pollutants in the air into the room after being treated by adsorption, decomposition or transformation, so as to improve the air quality. For indoor use, because no fresh air is introduced, the oxygen content in the air will gradually decrease, and you will feel stuffy when breathing indoors. Therefore, you need to open the window for ventilation at intervals. If the outdoor air quality is poor, untreated If the wind blows directly into the room, the original indoor air will deteriorate again.

现有带新风系统的空调，一般采用贯流风机，贯流风机是将机壳部分地敞开使气流直接沿径向进入风机，风机进风口的风力较集中，部分扇叶承受较大的压力，因而，贯流风机的抗阻力能力较弱，并且气流在叶轮内需要被强制折转，压头处空气的损失较大、获取的新风量太小，换气速度慢，换气效果不佳。Existing air conditioners with a fresh air system generally use a cross-flow fan. The cross-flow fan is to partially open the casing so that the airflow directly enters the fan along the radial direction. Therefore, the cross-flow fan has weak resistance to resistance, and the airflow needs to be forcibly turned inside the impeller. The loss of air at the pressure head is large, the fresh air volume obtained is too small, the ventilation speed is slow, and the ventilation effect is not good.

参照图1，空调室内机包括壳体(图中未示出)，壳体上设有室内进风口1和室内出风口3，离心风机4设置于壳体内，离心风机4与室内进风口1之间安装有换热器5，空气与换热器5进行热交换后，经离心风机4，从室内出风口3吹出。Referring to Fig. 1, the air conditioner indoor unit includes a housing (not shown in the figure), on which an indoor air inlet 1 and an indoor air outlet 3 are arranged, and a centrifugal fan 4 is arranged in the housing, between the centrifugal fan 4 and the indoor air inlet 1 A heat exchanger 5 is installed between them, and after the air exchanges heat with the heat exchanger 5, it is blown out from the indoor air outlet 3 through the centrifugal fan 4.

本发明实施例的空调室内机，包括壳体，壳体上开设室内进风口1、室外进风口2和室内出风口3，壳体内安装的离心风机4，设有第一进风侧41和第二进风侧42，第一进风侧41与室内进风口1相对设置，且两者之间设有换热器5，第二进风侧42与室外进风口2相对设置，离心风机4还设有出风侧43，如图1～2所示。The air conditioner indoor unit according to the embodiment of the present invention includes a housing on which an indoor air inlet 1, an outdoor air inlet 2 and an indoor air outlet 3 are provided, and the centrifugal fan 4 installed in the housing is provided with a first air inlet 41 and a second air inlet. Two air inlet sides 42, the first air inlet side 41 is arranged opposite to the indoor air inlet 1, and a heat exchanger 5 is arranged between the two, the second air inlet side 42 is arranged opposite to the outdoor air inlet 2, and the centrifugal fan 4 is also provided. An air outlet side 43 is provided, as shown in FIGS. 1-2 .

本发明实施例提供的空调室内机，由于壳体内设置的离心风机4包括第一进风侧41和第二进风侧42，第一进风侧41与室内进风口1相对设置，且两者之间设有换热器5，风从室内进风口1进入空调内，与换热器5进行换热后，再从室内出风口3排出，完成调节室内空气温度的功能；离心风机4的第二进风侧42与室外进风口2相对设置，室外的空气从室外进风口2经第二进风侧42进入离心风机4，因离心风机4是在机壳轴向侧板上开设进风口，气流沿轴向进入离心风机4，所有扇叶同时受力，空气与扇叶的接触面积大，因而，离心风机4的抗阻力能力较强，进风量大，从而，经离心风机4的出风侧43从室内出风口3吹出的出风量也相对较大，空调的换气速度快，克服了现有技术的缺陷，提高了空调换新风的效率。In the air-conditioning indoor unit provided by the embodiment of the present invention, since the centrifugal fan 4 provided in the housing includes a first air inlet side 41 and a second air inlet side 42, the first air inlet side 41 is arranged opposite to the indoor air inlet 1, and both There is a heat exchanger 5 between them, and the wind enters the air conditioner from the indoor air inlet 1, and after exchanging heat with the heat exchanger 5, it is discharged from the indoor air outlet 3 to complete the function of adjusting the indoor air temperature; the first centrifugal fan 4 The second air inlet side 42 is arranged opposite to the outdoor air inlet 2, and the outdoor air enters the centrifugal fan 4 from the outdoor air inlet 2 through the second air inlet side 42. Because the centrifugal fan 4 is provided with an air inlet on the axial side plate of the casing, The air flow enters the centrifugal fan 4 along the axial direction, and all the blades are stressed at the same time, and the contact area between the air and the blades is large. Therefore, the centrifugal fan 4 has a strong resistance to resistance and a large air intake. Therefore, the air outlet of the centrifugal fan 4 The air volume blown out from the indoor air outlet 3 by the side 43 is also relatively large, and the ventilation speed of the air conditioner is fast, which overcomes the defects of the prior art and improves the efficiency of the air conditioner for fresh air.

离心风机4包括风机轮毂44，风机轮毂44外周的上下边沿设有前盘45、后盘46，且前盘45与后盘46之间设有隔离板，将离心风机4的出风侧43分隔成前出风侧和后出风侧。若空调仅进行制冷或制热运转，室内空气仅能从离心风机4的第一进风侧41进入，最终从靠近前盘45的前出风侧吹出；若空调进行新风循环，空气仅从第二进风侧42进入，最后从靠近后盘46的后出风侧吹出，出风效率较低。因此，优选地，本发明实施例在离心风机4的风机轮毂44上开设连通第一进风口和第二进风侧42的引流孔47，如图3～5所示，这样当离心风机4单侧进风时，空气不仅可从相应一侧的前出风侧/后出风侧吹出，并且部分空气通过引流孔47流出，再经离心风机4另一侧的前出风侧/后出风侧吹出，因前出风侧和后出风侧同时出风，所以空调的出风效率较高，并且保证了离心风机4在单侧进风时也能高效低噪音运行。The centrifugal fan 4 includes a fan hub 44, the upper and lower edges of the fan hub 44 are provided with a front disc 45 and a rear disc 46, and a separation plate is arranged between the front disc 45 and the rear disc 46 to separate the air outlet side 43 of the centrifugal fan 4. into the front air outlet side and the rear air outlet side. If the air conditioner only performs cooling or heating operation, the indoor air can only enter from the first air inlet side 41 of the centrifugal fan 4, and finally blow out from the front air outlet side close to the front panel 45; The second air inlet side 42 enters, and finally blows out from the rear air outlet side close to the rear panel 46, and the air outlet efficiency is low. Therefore, preferably, the embodiment of the present invention provides a drainage hole 47 connecting the first air inlet and the second air inlet side 42 on the fan hub 44 of the centrifugal fan 4, as shown in FIGS. When the side air enters, the air can not only be blown out from the front air outlet side/rear air outlet side of the corresponding side, but also part of the air flows out through the drainage hole 47, and then passes through the front air outlet side/rear air outlet on the other side of the centrifugal fan 4 Side blowing, because the front air outlet side and the rear air outlet side are blowing out at the same time, so the air outlet efficiency of the air conditioner is high, and it ensures that the centrifugal fan 4 can also operate with high efficiency and low noise when the air is entering from one side.

进一步地，若在风机轮毂44随机开设若干引流孔47，空气经引流孔47进入另一出风侧的空气，在沿离心风机4的轴向风量不等，则室内出风口3各区域的出风不均，因此，优选地，本发明实施例围绕离心风机4的轴向均匀开设多个引流孔47，离心风机4的空气可沿离心风机4的轴向均匀从引流孔47流入另一出风侧，室内出风口3的各区域出风更均匀。Further, if a number of drainage holes 47 are randomly opened in the fan hub 44, the air enters the air on the other air outlet side through the drainage holes 47, and the air volume along the axial direction of the centrifugal fan 4 is not equal, the outlets of each area of the indoor air outlet 3 The wind is not uniform, therefore, preferably, the embodiment of the present invention evenly opens a plurality of drainage holes 47 around the axial direction of the centrifugal fan 4, and the air of the centrifugal fan 4 can flow into the other outlet evenly from the drainage holes 47 along the axial direction of the centrifugal fan 4. On the wind side, the air from each area of the indoor air outlet 3 is more uniform.

具体地，室内进风口1处设有室内风门，通过室内风门可将室内进风口1打开或闭合；室外进风口2处设有室外风门，通过室外风门可将室外进风口2打开或闭合。当室内空气质量优于室外空气时，打开室内风门并关闭室外风门，空调仅进行制冷或制热运转；当室外空气质量优于室内空气时，打开室外风门并关闭室内风门，空调运行新风系统，进行换气操作，将室外的空气传递至室内，有效提高室内空气的质量。尤其在夏天进行制冷时，若室外温度低于室内温度时，可关闭室内风门，仅打开室外风门，空调进行独立的换新风运转，能够有效降低空调的能耗。Specifically, the indoor air inlet 1 is provided with an indoor damper, through which the indoor air inlet 1 can be opened or closed; the outdoor air inlet 2 is provided with an outdoor damper, through which the outdoor air inlet 2 can be opened or closed. When the indoor air quality is better than the outdoor air, open the indoor damper and close the outdoor damper, the air conditioner will only perform cooling or heating operation; when the outdoor air quality is better than the indoor air, open the outdoor damper and close the indoor damper, the air conditioner will run the fresh air system, Perform ventilation operation, transfer the outdoor air to the room, and effectively improve the quality of the indoor air. Especially during cooling in summer, if the outdoor temperature is lower than the indoor temperature, the indoor damper can be closed, only the outdoor damper can be opened, and the air conditioner can perform independent fresh air replacement operation, which can effectively reduce the energy consumption of the air conditioner.

进一步地，若室外空气与室内空气的温差较大时，直接打开室外风门，室外空气大量涌入室内，会引起室内温度骤然下降，容易引发感冒等疾病，因而，本发明实施例室外风门的开度设置成可调的，如采用新风阀门21来调节室外风门的开度。根据实际需要，通过新风阀门21调节室外风门的开度，使室外空气逐渐流入室内，室内温度变化较慢，不易引发疾病，用户体验较好。Furthermore, if the temperature difference between the outdoor air and the indoor air is large, the outdoor damper is directly opened, and a large amount of outdoor air flows into the room, which will cause a sudden drop in the indoor temperature and easily cause diseases such as colds. Therefore, the opening of the outdoor damper in the embodiment of the present invention Degree is set to be adjustable, as adopting fresh air valve 21 to regulate the opening degree of outdoor damper. According to actual needs, the opening of the outdoor air door is adjusted through the fresh air valve 21, so that the outdoor air gradually flows into the room, and the indoor temperature changes slowly, which is not easy to cause diseases, and the user experience is better.

若室内的空气含氧量下降，但室外的空气质量较差，直接从室外吹入的空气会污染室内的空气，导致室内的空气质量下降。因此，优选地，本发明实施例的离心风机4的第二进风侧42与室外进风口2之间还设有空气净化模块6，室外空气经空气净化模块6处理后，空气质量有所提高，因此，室外空气流入室内后，室内空气的含氧量和质量均得到提升。If the oxygen content of the indoor air drops, but the outdoor air quality is poor, the air directly blown in from the outside will pollute the indoor air, resulting in a decline in the indoor air quality. Therefore, preferably, an air purification module 6 is also provided between the second air inlet side 42 of the centrifugal fan 4 of the embodiment of the present invention and the outdoor air inlet 2, after the outdoor air is processed by the air purification module 6, the air quality is improved Therefore, after the outdoor air flows into the room, the oxygen content and quality of the indoor air are improved.

此外，若在室外空气和室内空气的质量均较差时，打开室外风门运行新风系统，室外空气经空气净化模块6处理后进入室内，改善室内空气质量，又因室外空气与室内空气之间一般有温差，室外空气进入室内后使室内空气的温度出现变化，因而，室内空气需要再进行温度调节，导致能耗较高。优选地，本发明实施例在壳体上对应空气净化模块6的位置开设有室内净化进风口，室内空气可直接通过室内净化进风口进入空调内，经空气净化模块6处理后的空气，再从室内出风口3排出，室内空气质量得到改善，并且经空气净化模块6处理后的室内空气重新进入室内，不会引起室内空气的温度变化，因而该过程不需温度调节，能耗相对较低。In addition, if the quality of both outdoor air and indoor air is poor, open the outdoor air door to run the fresh air system, and the outdoor air will enter the room after being processed by the air purification module 6 to improve the indoor air quality. There is a temperature difference, and the temperature of the indoor air changes after the outdoor air enters the room. Therefore, the temperature of the indoor air needs to be adjusted again, resulting in high energy consumption. Preferably, in the embodiment of the present invention, an indoor purification air inlet is provided at the position corresponding to the air purification module 6 on the housing, and the indoor air can directly enter the air conditioner through the indoor purification air inlet, and the air treated by the air purification module 6 is then released from the The indoor air outlet 3 is exhausted, the indoor air quality is improved, and the indoor air treated by the air purification module 6 re-enters the room without causing temperature changes of the indoor air, so this process does not require temperature adjustment, and the energy consumption is relatively low.

室内净化进风口处还设有净化进风风门，净化进风风门可将室内净化进风口打开或闭合。当不需要进行室内空气净化时，将净化风门关闭，减少能耗。The indoor purification air inlet is also provided with a purification air inlet door, which can open or close the indoor purification air inlet. When indoor air purification is not required, the air purification door is closed to reduce energy consumption.

同理，上述的净化进风风门的开度也是可调的，本发明实施例采用净化空气阀门61调节进风风门的开度。当室内空气优于室外时，新风阀门21和净化空气阀门61均关闭，空调进行制冷或制热运转；当室内空气质量下降时，打开净化进风风门和室外风门，并根据具体情况，通过净化空气阀门61调节净化进风风门的开度，以及通过新风阀门21调节空气室外风门的开度，使空调同时进行室内空气的净化、新风循环和温度调节；若空调同时进行制冷调节和空气净化运转，可实现冷风和净化常温空气预混合，出风口吹出的空气，其温度凉而不冰，提高了温度的舒适性；当室内温度不需要调节时，通过运动机构关闭室内风门，打开净化进风风门和净化空气阀门61，进行单独的空气净化运转，并根据室内空气的含氧量，调节新风阀门21的开度，控制室外空气流入室内的速度，提高室内空气的质量和含氧量。In the same way, the opening of the air-purifying damper mentioned above is also adjustable, and the embodiment of the present invention uses a clean air valve 61 to adjust the opening of the air-intake damper. When the indoor air is better than the outdoor air, both the fresh air valve 21 and the purified air valve 61 are closed, and the air conditioner performs cooling or heating operation; The air valve 61 adjusts the opening of the purifying air intake damper, and adjusts the opening of the air outdoor damper through the fresh air valve 21, so that the air conditioner can purify the indoor air, fresh air circulation and temperature adjustment at the same time; if the air conditioner simultaneously performs cooling adjustment and air purification operation , can realize the pre-mixing of cold air and purified normal temperature air, the air blown out of the air outlet is cool but not ice, which improves the comfort of the temperature; when the indoor temperature does not need to be adjusted, the indoor damper is closed by the movement mechanism, and the purified air is opened The damper and the clean air valve 61 perform separate air purification operation, and adjust the opening of the fresh air valve 21 according to the oxygen content of the indoor air, so as to control the speed of outdoor air flowing into the room and improve the quality and oxygen content of the indoor air.
