随着生活水平的提高，空调器已经成为众多家庭不可或缺的家用电器之一。现有的空调器大多同时具有制冷及制热功能，以使室内环境温度维持在舒适的范围内。当空调器长时间处于制冷或制热模式时，由于冷风或热风长时间直吹人体，会给用户造成不适感。为了克服上述不足，市面上出现了具有无风感功能的空调器，但现有的空调器大多通过检测室内的温度或湿度以控制空调器进入相应的无风感状态，而并非根据用户的实际人体感受选择相应的无风感状态，使得实际的无风感效果与预期效果偏离较大；并且现有的空调器很难实现切换至无风感状态的平稳过渡，使得用户感受到的风感区别过大，导致用户体验不佳。With the improvement of living standards, air conditioners have become one of the indispensable household appliances for many families. Most of the existing air conditioners have both cooling and heating functions to maintain the indoor ambient temperature within a comfortable range. When the air conditioner is in the cooling or heating mode for a long time, the user may feel uncomfortable because the cold air or the hot air blows the human body for a long time. In order to overcome the above-mentioned deficiencies, air conditioners having a windless function have appeared on the market, but most of the existing air conditioners control the temperature and humidity of the room to control the air conditioner to enter a corresponding state of no wind, and not according to the actual situation of the user. The human body feels the corresponding windless state, which makes the actual windless effect deviate greatly from the expected effect; and the existing air conditioner is difficult to achieve a smooth transition to the windless state, so that the user feels the wind feeling. The difference is too large, resulting in poor user experience.

Specifically, the first air guiding plate 120 is rotatably mounted on the housing 100 by the first pivot shaft 121. It should be noted that the first pivot shaft 121 may be a long axis extending along the length direction of the first air guiding plate 120.

温度传感器160设置为检测室内目标热源的散热量，此处的目标热源指的是室内活动热源，可根据该空调器的实际服务对象确定目标热源。例如，在一般情况下，空调器的目标服务对象为人，此时的目标热源即为人体。当然，在一些特殊情况下，例如在动物园的动物活动室内安装的空调室内机，该目标热源即为动物。需要说明的是，该温度传感器160主要设置为检测室内目标的散热量，并根据检测结果确定目标热源的体感情况。具体地，上述温度传感器160可为热电堆红外测温传感器，利用红外辐射测温原理即可实现非接触式温度测量。控制器可设于空调室内机的主控电路板上，用以对空调室内机的风机、第一导风板120、第二导风板130及第三导风板140进行控制。The temperature sensor 160 is configured to detect the amount of heat dissipation of the target target heat source. The target heat source herein refers to the indoor active heat source, and the target heat source can be determined according to the actual service object of the air conditioner. For example, in general, the target service object of the air conditioner is a person, and the target heat source at this time is the human body. Of course, in some special cases, such as an air-conditioned indoor unit installed in an animal activity room of a zoo, the target heat source is an animal. It should be noted that the temperature sensor 160 is mainly configured to detect the amount of heat dissipation of the indoor target, and determine the body condition of the target heat source according to the detection result. Specifically, the temperature sensor 160 may be a thermopile infrared temperature sensor, and the non-contact temperature measurement can be realized by using the infrared radiation temperature measurement principle. The controller may be disposed on the main control circuit board of the air conditioner indoor unit to control the fan of the air conditioner indoor unit, the first air deflector 120, the second air deflector 130, and the third air deflector 140.
具体的，第一导风板120、第二导风板130及第三导风板140之间相互配合可形成多个由冷至热的无风感阶段。需要说明的是此处的冷和热是指无风感各阶段所带给用户的相对感受来划分的，而并非真正的冷风或热风。Specifically, the first air deflector 120, the second air deflector 130, and the third air deflector 140 cooperate with each other to form a plurality of stages of cold and hot windlessness. It should be noted that the cold and heat here refers to the relative feelings brought to the user at each stage of the windlessness, and is not really cold or hot.
例如，在关机状态下，如图4所示，第三导风板140置于壳体100的风道110内，第一导风板120的远离第一枢轴121的边缘与第二导风板130的靠近第二枢轴131的边缘相接。在第一导风板120与第二导风板130的配合下使出风口闭合，一方面能够防止灰尘从出风口进入，另一方面能够使空调室内机整体更为美观。For example, in the off state, as shown in FIG. 4, the third air deflector 140 is disposed in the air duct 110 of the housing 100, and the edge of the first air deflector 120 away from the first pivot 121 and the second air guide The edge of the plate 130 adjacent to the second pivot 131 meets. The air outlet is closed by the cooperation of the first air deflector 120 and the second air deflector 130.

在舒适级无风感阶段，如图6所示，第一导风板120的前端与第二导风板130的后端密封配合，第三导风板140转至与前壁面111贴合，以使气流由第二导风板130的上侧的气流通道流出。在此阶段，相对于冷级无风感阶段进一步减小了风力输出，从而给用户相对舒适的感受。In the stage of the comfort level and no wind, as shown in FIG. 6 , the front end of the first air guiding plate 120 is sealingly engaged with the rear end of the second air guiding plate 130 , and the third air guiding plate 140 is turned into the front wall surface 111 . The airflow is caused to flow out from the airflow passage on the upper side of the second air deflector 130. At this stage, the wind output is further reduced relative to the cold level windless stage, giving the user a relatively comfortable feel.
在热级无风感阶段，如图7所示，第一导风板120的前端与第二导风板130的后端密封配合，第三导风板140转动至出风的流通面上，以使气流由第三导风板140的散风孔142吹出。在此阶段，气流只能经散风孔142打散后吹出，也即使风力输出降到最低，此时相对于其他阶段，本阶段给用户较热的感受。In the stage of the hot stage and no wind, as shown in FIG. 7 , the front end of the first air deflector 120 is sealingly engaged with the rear end of the second air deflector 130 , and the third air deflector 140 is rotated to the flow surface of the air outlet. The air flow is blown out by the air diffusing holes 142 of the third air guiding plate 140. At this stage, the airflow can only be blown out after being dispersed by the blast hole 142, and even if the wind output is minimized, at this time, the user feels hotter than the other stages.
此外，在各个无风感阶段，还可通过控制器控制风机转速，从而将各无风感阶段细分为多个由冷至热渐变的无风感子区间，从而使无风感阶段控制更为精细化，过渡更为平稳。In addition, in each stage of no wind feeling, the fan speed can also be controlled by the controller, thereby subdividing each windless stage into a plurality of wind-insensitive sub-ranges from cold to hot gradation, thereby making the windless stage control more For the sake of refinement, the transition is more stable.

下面参考图5至图9详细描述根据本申请实施例的空调室内机的控制方法，其中空调室内机为根据本申请上述实施例的空调室内机，空调室内机包括无风感模式、制冷模式和制热模式，无风感模式包括多个由冷至热的无风感阶段，该空调室内机的具体结构参照上述实施例，因此至少具有上述实施例的技术方案所带来的所有技术效果，在此不再一一赘述。A method for controlling an indoor unit of an air conditioner according to an embodiment of the present application is described in detail below with reference to FIG. 5 to FIG. 9, wherein the air conditioner indoor unit is an air conditioner indoor unit according to the above embodiment of the present application, and the air conditioner indoor unit includes a windless mode, a cooling mode, and The heating mode, the windless mode includes a plurality of stages of cold and heat, and the specific structure of the air conditioning indoor unit refers to the above embodiment, so that at least all the technical effects brought by the technical solutions of the above embodiments are obtained. I will not repeat them here.
具体地，空调室内机具有制冷模式、制热模式及无风感模式。空调室内机的面板150或者空调遥控器上设置有多个按钮，通过不同的按钮选择不同的出风模式。其中，无风感模式包括多个由冷至热的无风感阶段，以下主要针对空调室内机在无风感模式下的控制方法进行详细说明。如图8及图9所示，根据本申请实施例的空调室内机的控制方法包括如下步骤：Specifically, the air conditioning indoor unit has a cooling mode, a heating mode, and a windless mode. A plurality of buttons are provided on the panel 150 of the air conditioner indoor unit or the air conditioner remote controller, and different air outlet modes are selected by different buttons. Among them, the windless mode includes a plurality of windless to cool stages, and the following mainly describes the control method of the air conditioner indoor unit in the windless mode. As shown in FIG. 8 and FIG. 9 , the control method of the air conditioner indoor unit according to the embodiment of the present application includes the following steps:
步骤S1，利用室内温度传感器160获取室内目标热源的散热量。例如，以人体温度传感器160为例，人体温度传感器160利用红外辐射探测人体体表的散热量以获取人体温度信息。In step S1, the indoor temperature sensor 160 is used to obtain the heat dissipation amount of the indoor target heat source. For example, taking the human body temperature sensor 160 as an example, the human body temperature sensor 160 uses infrared radiation to detect the amount of heat dissipation of the body surface to obtain body temperature information.
步骤S2，人体温度传感器160可通过自身的转换模块将获取的散热量转换为目标热源的体感参考温度，将该体感参考温度与空调室内机的当前设定温度进行比较，控制器通过比较值控制空调室内机进入相应的无风感阶段。In step S2, the human body temperature sensor 160 can convert the obtained heat dissipation amount into the somatosensory reference temperature of the target heat source through its own conversion module, compare the somatosensory reference temperature with the current set temperature of the air conditioner indoor unit, and the controller controls the comparison value. The air conditioner indoor unit enters the corresponding stage of no wind feeling.
具体地，当体感参考温度大于当前设定温度，且二者温差的绝对值大于第一预设值时，控制空调室内机向热的方向调节一个或多个无风感阶段、修改当前设定温度并进入步骤S1；其中，第一预设值为大于或等于零的自然数。需要指出的是每一无风感阶段均对应不同的当前预设温度，为了便于说明，将体感参考温度定义为Tc，每一阶段空调室内机的当前设定温度定义为Ts(n)，第一预设值为M。Specifically, when the somatosensory reference temperature is greater than the current set temperature, and the absolute value of the temperature difference is greater than the first preset value, the air conditioner indoor unit is controlled to adjust one or more windless stages to the hot direction, and the current setting is modified. The temperature proceeds to step S1; wherein the first preset value is a natural number greater than or equal to zero. It should be pointed out that each windless phase corresponds to a different current preset temperature. For convenience of explanation, the somatosensory reference temperature is defined as Tc, and the current set temperature of the air conditioner indoor unit in each stage is defined as Ts(n), A default value is M.
例如，当空调室内机处于无风感第一阶段时，若温度传感器160检测到Tc大于Ts(1)，且Tc与Ts(1)的差值大于M，则判定空调当前设定温度相对于人体较低，且二者温差较大，此时控制器会通过调控第一导风板120、第二导风板130及第三导风板140的摆动角度以减小风力输出，而使空调器处于热的无风感阶段，从而使用户有相对升温的感受，相应地，空调室内机的当前运行温度也自动修改为TS(n)，并重复上述步骤，以使人体感受在任何时刻都处于最佳状态。For example, when the air conditioner indoor unit is in the first stage of no wind feeling, if the temperature sensor 160 detects that Tc is greater than Ts(1), and the difference between Tc and Ts(1) is greater than M, it is determined that the current set temperature of the air conditioner is relative to The human body is lower, and the temperature difference between the two is relatively large. At this time, the controller adjusts the swing angles of the first air deflector 120, the second air deflector 130, and the third air deflector 140 to reduce the wind output, and the air conditioner The device is in a hot, windless phase, so that the user has a relatively warm feeling. Accordingly, the current operating temperature of the air conditioner indoor unit is also automatically modified to TS(n), and the above steps are repeated to make the human body feel at any time. In the best condition.
当空调室内机处于无风感第n阶段时，若温度传感器160检测到Tc小于Ts(n)，且Ts(n)与Tc的差值大于M，则判定空调设定温度相对于人体较高，且二者温差较大，此时控制器会通过调控第一导风板120、第二导风板130及第三导风板140的摆动角度以增大风力输出，而使空调器处于冷的无风感阶段，从而使用户有相对降温的感受，相应地，空调室内机的当前运行温度也自动修改为TS(n-1)，并重复上述步骤，以使人体感受在任何时刻都处于最佳状态。When the air conditioner indoor unit is in the nth stage of no wind feeling, if the temperature sensor 160 detects that Tc is less than Ts(n), and the difference between Ts(n) and Tc is greater than M, it is determined that the air conditioner set temperature is higher than the human body. And the temperature difference between the two is relatively large. At this time, the controller adjusts the swing angle of the first air deflector 120, the second air deflector 130, and the third air deflector 140 to increase the wind output, and the air conditioner is cold. The windless phase, so that the user has a relatively cool feeling, correspondingly, the current operating temperature of the air conditioner indoor unit is also automatically modified to TS (n-1), and the above steps are repeated, so that the human body feels at any moment Best state.
进一步地，多个由冷至热的无风感阶段包括冷级无风感阶段和热级无风感阶段。在冷级无风感阶段，如图5所示，转动第一导风板120及第二导风板130，在第二导风板130的上下两侧形成两气流通道，以使气流由第二导风板130上下两侧的两个气流通道流出，此时空调室内机的风力输出最大，给用户以相对较冷的感受。在热级无风感阶段，如图7所示，转动第一导风板120，以将第一导风板120的前端与第二导风板130的后端密封配合，转动第三导风板140至出风的流通面上，以使气流由第三导风板140的散风孔142吹出，此时空调室内机的风力输出最大，给用户以相对较冷的感受。Further, a plurality of cold to hot windless stages include a cold level windless stage and a hot stage windless stage. In the stage of the cold level and no wind, as shown in FIG. 5, the first air deflector 120 and the second air deflector 130 are rotated, and two airflow passages are formed on the upper and lower sides of the second air deflector 130, so that the airflow is The two airflow channels on the upper and lower sides of the second air deflector 130 flow out. At this time, the air output of the air conditioner indoor unit is the largest, giving the user a relatively cold feeling. In the stage of the heat level and no wind, as shown in FIG. 7 , the first air deflector 120 is rotated to seal the front end of the first air deflector 120 and the rear end of the second air deflector 130 to rotate the third air guide. The plate 140 is on the flow surface of the air outlet so that the air flow is blown out by the air diffusing holes 142 of the third air guiding plate 140. At this time, the air output of the air conditioning indoor unit is maximized, giving the user a relatively cold feeling.
当体感参考温度大于当前设定温度，且二者温差的绝对值大于第一预设值时，控制空调室内机进入热级无风感阶段；当体感参考温度小于当前设定温度，且二者温差的绝对值大于第一预设值时，控制空调室内机进入冷级无风感阶段。When the somatosensory reference temperature is greater than the current set temperature, and the absolute value of the temperature difference is greater than the first preset value, the air conditioner indoor unit is controlled to enter the thermal level windless phase; when the somatosensory reference temperature is less than the current set temperature, and both When the absolute value of the temperature difference is greater than the first preset value, the air conditioner indoor unit is controlled to enter the cold level and no wind feeling stage.
进一步地，冷级无风感阶段及热级无风感阶段均包括至少三个由冷至热渐变设置的无风感子区间；随着无风感子区间由冷向热切换，风机的转速相应地由大向小切换。Further, the cold-level windless phase and the hot-level windless phase include at least three wind-insensitive sub-ranges set from cold to hot gradual change; the fan speed is switched from cold-to-heat switching to the wind-insensitive sub-interval Switch from large to small accordingly.
在本实施例中，可根据空调室内机的实际运行温度及风速将各无风感阶段划分为多个无风感子区间，各无风感子区间由冷至热渐变，相应地，各无风感子区间内的风机转速也由大向小切换。具体地，例如，如图9所示，冷级无风感阶段包括三个无风感子区间，分别为区间M1、区间M2及区间M3，从区间M1至区间M3，空调室内机的风力输出逐渐减小，也即给用户的冷感程度逐渐减小。热级无风感阶段包括三个无风感子区间，分别为区间M7、区间M8及区间M9，从区间M7至区间M9，空调室内机的风力输出进一步逐渐减小，即给用户的热感程度逐渐增大。如此，通过将各无风感阶段进一步细分为多个无风感子区间，从而使无风感阶段由冷至热的变化过程更为平稳。同样地，温度传感器160检测用户的散热量并转换成对应的体感参考温度，将体感参考温度与空调室内机在相应的无风感子区间内的当前设定温度进行比较，控制器根据比较结果选择进入相应的无风感子区间，以给用最佳的体验。In this embodiment, each wind-free phase can be divided into a plurality of wind-insensitive sub-intervals according to the actual operating temperature and the wind speed of the air-conditioning indoor unit, and each wind-insensitive sub-range is changed from cold to hot, and correspondingly, none The fan speed in the wind-sensing section is also switched from large to small. Specifically, for example, as shown in FIG. 9 , the cold level windless phase includes three windless sensory sections, namely, section M1, section M2, and section M3, and wind output of the air conditioner indoor unit from section M1 to section M3. Gradually decrease, that is, the degree of coldness to the user is gradually reduced. The hot level windless phase includes three windless sensory intervals, namely interval M7, interval M8 and interval M9. From interval M7 to interval M9, the wind output of the air conditioner indoor unit is further reduced, that is, giving the user a sense of heat. The degree is gradually increasing.
