本发明的空调及其控制方法中，空调设置了一种“除湿热控制模式”，特别适用于夏季高温高湿的环境启用。在“除湿热控制模式”下，空调分为三个阶段运行，分别为除湿阶段、第一制冷阶段和第二制冷阶段。除湿阶段用于除湿，使室内湿度快速下降。第一制冷阶段用于室内环境降温，使室内环境尽快达到人体预期；第二制冷阶段用于维持制冷效果，且相比第一制冷阶段减小风力或提高送风发散度，以使冷风气流更加柔和，提高人体舒适感。In the air conditioner and control method thereof of the present invention, the air conditioner is provided with a "dehumidification heat control mode", which is particularly suitable for use in high temperature and high humidity environments in summer.

Moreover, this intelligent adjustment also saves air conditioning energy consumption, achieving the goal of energy saving and emission reduction.

本发明实施例一方面提供了一种空调。空调用于对室内空气进行调节，包括调节空气的温度、湿度、空气质量、对室内空气进行加湿、除湿、引入新风等等。空调由蒸发器、冷凝器、压缩机、节流装置以及其他必要的元件构成蒸气压缩制冷循环***，以通过室内侧的风机输出冷风/热风，实现对室内环境的制冷和制热。In one aspect, an embodiment of the present invention provides an air conditioner. The air conditioner is used to adjust indoor air, including adjusting the temperature, humidity, and air quality of the air, humidifying and dehumidifying the indoor air, introducing fresh air, etc. The air conditioner is composed of an evaporator, a condenser, a compressor, a throttling device, and other necessary components to form a vapor compression refrigeration cycle system, so as to output cold air/hot air through a fan on the indoor side to achieve cooling and heating of the indoor environment.
本发明实施例的空调可以为家用空调，也可以为中央空调。具体地，空调的具体形式可以为分体壁挂式、分体立式、整体式、天井式等各种形式。图1至图5示意了壁挂式空调的室内机。The air conditioner of the embodiment of the present invention can be a household air conditioner or a central air conditioner. Specifically, the specific form of the air conditioner can be a split wall-mounted type, a split vertical type, an integral type, a patio type, etc. Figures 1 to 5 illustrate the indoor unit of a wall-mounted air conditioner.
图1是根据本发明一个实施例的空调的室内机结构示意图；图2根据图1所示室内机在隐藏了导风板后的示意性前视图；图3是图2所示室内机在导风板处于最大出风位置时的示意性剖视放大图；图4是图3所示室内机在导风板处于上扬导风位置时的示意图；图5是图3所示室内机在导风板处于环抱导风位置时的示意图。Fig. 1 is a schematic diagram of the structure of an indoor unit of an air conditioner according to an embodiment of the present invention; Fig. 2 is a schematic front view of the indoor unit shown in Fig. 1 after the air guide plate is hidden; Fig. 3 is a schematic enlarged sectional view of the indoor unit shown in Fig. 2 when the air guide plate is in the maximum air outlet position; Fig. 4 is a schematic diagram of the indoor unit shown in Fig. 3 when the air guide plate is in the upward air guide position; Fig. 5 is a schematic diagram of the indoor unit shown in Fig. 3 when the air guide plate is in the embracing air guide position.
如图1至图5所示，空调的室内机包括壳体10。壳体10限定有容纳空间，以用于容纳壁挂式空调室内机的主体部件，包括蒸发器20、风机30等等。壳体10的前侧下部开设有出风口12，以用于吹出换热气流。壳体10可为长度方向(x方向)沿水平横向的长条状。壳体10的顶部可开设有进风口11，用于吸入室内空气。壳体10内部限定有风道15，风道15的出口连通出风口12。风机30设置于壳体10内，用于将壳体10内的调节气流经风道15吹出出风口12，以调节室内空气。调节气流例如为换热气流(冷风气流、热风气流)、净化气流、加湿气流、新风气流等等。As shown in Figures 1 to 5, the indoor unit of the air conditioner includes a housing 10. The housing 10 defines a storage space for accommodating the main components of the wall-mounted air conditioner indoor unit, including an evaporator 20, a fan 30, and the like. An air outlet 12 is provided at the lower front side of the housing 10 for blowing out a heat exchange airflow. The housing 10 may be a long strip along the horizontal transverse direction in the length direction (x direction). An air inlet 11 may be provided at the top of the housing 10 for inhaling indoor air. An air duct 15 is defined inside the housing 10, and the outlet of the air duct 15 is connected to the air outlet 12. The fan 30 is arranged in the housing 10, and is used to blow the conditioned airflow in the housing 10 out of the air outlet 12 through the air duct 15 to regulate the indoor air. The conditioned airflow is, for example, a heat exchange airflow (cold airflow, hot airflow), a purified airflow, a humidified airflow, a fresh airflow, and the like.
如图2所示，空调还包括设置在出风口12处以用于左右摆风的摆叶组件60。摆叶组件60具体包括多个摆叶61，多个摆叶61在驱动机构的驱动下实现同步地左摆动/右摆动、循环往复摆动，或者是保持在某个角度，以进行定向导风。能实现摆叶同步摆动的驱动机构在空调领域广泛应用，例如可包括电机、摇杆和连杆，具体不再赘述。As shown in FIG. 2 , the air conditioner further includes a swing blade assembly 60 disposed at the air outlet 12 for swinging air left and right. The swing blade assembly 60 specifically includes a plurality of swing blades 61, which are driven by a driving mechanism to swing left/right synchronously, swing back and forth in a cycle, or remain at a certain angle for directional air guidance. A driving mechanism capable of achieving synchronous swinging of the swing blades is widely used in the field of air conditioning, and may include, for example, a motor, a rocker, and a connecting rod, which will not be described in detail.
摆叶组件60具有使出风流量最大的角度，具体为使每个摆叶61所在平 面垂直于出风口12所在平面。换言之，使每个摆叶61所在平面垂直于壳体10的横向方向。如此使每个摆叶61平行于吹向其的气流方向，使摆叶61的侧边面对来风气流，对气流的阻碍最小，而且也使相邻摆叶件的距离最大，使出风最顺畅。The swing blade assembly 60 has an angle that maximizes the air flow rate, specifically, each swing blade 61 is located at a plane The surface is perpendicular to the plane where the air outlet 12 is located. In other words, the plane where each swing blade 61 is located is perpendicular to the horizontal direction of the housing 10. In this way, each swing blade 61 is parallel to the direction of the air flow blowing toward it, so that the side of the swing blade 61 faces the incoming air flow, which minimizes the obstruction to the air flow, and also maximizes the distance between adjacent swing blades, so that the air flow is smoothest.
摆叶组件60还具有使出风流量最小的角度，具体为使各个摆叶61转动至共面或者尽最大可能接近共面的状态，以便使摆叶61的大表面面对来风气流，对气流的阻碍最强，使出风流量最小。The swing blade assembly 60 also has an angle that minimizes the air flow rate, specifically by rotating each swing blade 61 to be coplanar or as close to coplanar as possible, so that the large surface of the swing blade 61 faces the incoming air flow, which has the strongest obstruction to the air flow and minimizes the air flow rate.
如图3至图5所示，空调还包括多个导风板51、52。多个导风板51、52均可转动地安装于壳体10，且位于出风口12处，用于调节出风口12的出风面积和出风方向。As shown in Figures 3 to 5, the air conditioner further includes a plurality of air guide plates 51, 52. The plurality of air guide plates 51, 52 are rotatably mounted on the housing 10 and are located at the air outlet 12 for adjusting the air outlet area and air outlet direction of the air outlet 12.
多个导风板51、52的转动轴线均平行于壳体10的横向方向，用于上下导风，也即引导出风口12的俯仰角度，或者称为上下出风角度，也就是气流与水平面的夹角。具体地，可使多个导风板数量可以为两个，分别为上下排列的导风板51和导风板52。可使出风口12朝前下方敞开，使导风板51和导风板52分别位于出风口12的前侧和下侧。每个导风板各自匹配有电机(未图示)，每个电机各自独立地接受控制器800的控制。The rotation axes of the multiple air guide plates 51 and 52 are parallel to the lateral direction of the housing 10, and are used to guide the wind up and down, that is, to guide the pitch angle of the air outlet 12, or the up and down air outlet angle, that is, the angle between the airflow and the horizontal plane. Specifically, the number of the multiple air guide plates can be two, namely, the air guide plate 51 and the air guide plate 52 arranged up and down. The air outlet 12 can be opened to the front and bottom, so that the air guide plate 51 and the air guide plate 52 are respectively located at the front side and the lower side of the air outlet 12. Each air guide plate is matched with a motor (not shown), and each motor is independently controlled by the controller 800.
多个导风板51、52处于不同的角度时，出风口12的出风面积显然是不同的。例如，在空调关机或待机时，使多个导风板来封闭出风口12，使出风面积接近为0。在图3所示状态，各导风板51、52均大致平行于风道15内气流流动方向，对气流阻碍最小，构成“使出风口12的出风面积最大的最大出风位置”。When the multiple air guide plates 51, 52 are at different angles, the air outlet area of the air outlet 12 is obviously different. For example, when the air conditioner is turned off or on standby, the multiple air guide plates are used to close the air outlet 12, so that the air outlet area is close to 0. In the state shown in FIG. 3, each air guide plate 51, 52 is roughly parallel to the air flow direction in the air duct 15, with minimal obstruction to the air flow, forming a "maximum air outlet position that maximizes the air outlet area of the air outlet 12".
如图4所示，多个导风板51、52还具有朝前上方导风的上扬导风位置，使气流上扬后再在自身重力作用下下沉，使送风距离更远，送风范围更大。As shown in FIG. 4 , the plurality of air guide plates 51 , 52 also have an upward air guide position for guiding the air forward and upward, so that the air flow rises and then sinks under its own gravity, so that the air supply distance is longer and the air supply range is larger.
如图5所示，多个导风板51、52还具有使部分导风板51朝前导风，其他部分导风板52朝下导风的环抱导风位置。如此使两股气流分别从用户的上侧和下侧向前流动，然后在用户后侧进行汇合，形成环抱式送风效果。As shown in Fig. 5, the plurality of air guide plates 51 and 52 also have an encircling air guide position where some air guide plates 51 guide air forward and other air guide plates 52 guide air downward. In this way, two air flows flow forward from the upper side and the lower side of the user respectively, and then converge at the rear side of the user, forming an encircling air supply effect.
图6是根据本发明一个实施例的空调的示意性框图。FIG. 6 is a schematic block diagram of an air conditioner according to an embodiment of the present invention.
如图6所示，本发明实施例的空调还包括控制器800。控制器800包括处理器810和存储器820，存储器820存储有计算机程序821，计算机程序821被处理器810执行时用于实现本发明任一实施例的空调的控制方法。As shown in Fig. 6, the air conditioner of the embodiment of the present invention further includes a controller 800. The controller 800 includes a processor 810 and a memory 820. The memory 820 stores a computer program 821. When the computer program 821 is executed by the processor 810, it is used to implement the control method of the air conditioner of any embodiment of the present invention.
本发明另一方面提供了空调的控制方法。图7是根据本发明一个实施例 的空调的控制方法的示意图。Another aspect of the present invention provides a method for controlling an air conditioner. Schematic diagram of a control method of an air conditioner.
如图7所示，本发明实施例的空调的控制方法一般性地可包括：As shown in FIG. 7 , the control method of the air conditioner according to the embodiment of the present invention may generally include:
步骤S702：接收除湿热控制模式开启指令。Step S702: receiving a dehumidification heat control mode start instruction.
具体地，用户希望空调运行“除湿热控制模式”时，可对遥控器、线控器、空调主机的控制面板或者其他与空调进行无线连接的智能终端设备等控制端进行相应操作，使其向空调的控制器800发出除湿热控制模式的开启指令。Specifically, when the user wants the air conditioner to run the "dehumidification heat control mode", he or she can perform corresponding operations on the control end such as the remote control, wired controller, control panel of the air conditioner host, or other smart terminal devices wirelessly connected to the air conditioner, so that it sends a start instruction of the dehumidification heat control mode to the air conditioner controller 800.
步骤S704：控制空调运行除湿阶段。Step S704: Control the air conditioner to run the dehumidification stage.
空调可采用蒸气压缩制冷循环***进行除湿/制冷/制热。蒸气压缩制冷循环***在制冷模式和除湿模式下的制冷剂循环流动的方向是一致的。也即，除湿阶段也需要循环***运行制冷，使室内空气中的水蒸气凝结在蒸发器的低温表面，达到除湿目的。Air conditioners can use a vapor compression refrigeration cycle system for dehumidification/cooling/heating. The refrigerant circulation flow direction of the vapor compression refrigeration cycle system in the cooling mode and dehumidification mode is the same. That is, the dehumidification stage also requires the circulation system to operate refrigeration so that the water vapor in the indoor air condenses on the low-temperature surface of the evaporator to achieve the purpose of dehumidification.
步骤S706：判断除湿阶段是否满足预设的第一切换条件。若满足则执行步骤S708，也即将空调切换至第一制冷阶段。若不满足则继续执行步骤S704，也就是使空调继续运行除湿阶段。Step S706: Determine whether the dehumidification stage meets the preset first switching condition. If so, execute step S708, that is, switch the air conditioner to the first cooling stage. If not, continue to execute step S704, that is, make the air conditioner continue to run the dehumidification stage.
步骤S708：控制空调运行第一制冷阶段。Step S708: Control the air conditioner to run the first cooling stage.
步骤S710：判断第一制冷阶段是否满足预设的第二切换条件。若满足则执行步骤S712，也即控制空调切换至第二制冷阶段。若不满足则继续执行步骤S708，也就是使空调继续运行第一制冷阶段。Step S710: Determine whether the first cooling stage meets the preset second switching condition. If so, execute step S712, that is, control the air conditioner to switch to the second cooling stage. If not, continue to execute step S708, that is, make the air conditioner continue to run the first cooling stage.
步骤S712：控制空调运行第二制冷阶段，以减小风力或提高送风发散度。即，相比第一制冷阶段，第二制冷阶段的风力减小，风力包括风速、风量等参数。送风发散度指的是冷风气流吹向室内的集中程度，冷风气流集中朝某一方向吹送，则发散度较低，聚集性较高；冷风气流同时朝多个方向吹送，则聚集性较低，发散度较高。Step S712: Control the air conditioner to run the second cooling stage to reduce the wind force or increase the air supply divergence. That is, compared with the first cooling stage, the wind force in the second cooling stage is reduced, and the wind force includes parameters such as wind speed and air volume. The air supply divergence refers to the concentration of the cold air flow blowing into the room. If the cold air flow is concentrated in a certain direction, the divergence is low and the concentration is high; if the cold air flow is blown in multiple directions at the same time, the concentration is low and the divergence is high.
本发明实施例的空调及其控制方法中，空调设置了一种“除湿热控制模式”，特别适用于夏季高温高湿的环境启用，例如中国东南沿海地区的夏季环境。在“除湿热控制模式”下，空调分为三个阶段运行，分别为除湿阶段、第一制冷阶段和第二制冷阶段。除湿阶段用于除湿，使室内湿度快速下降；第一制冷阶段用于室内全力降温，使室内环境尽快达到人体预期；第二制冷阶段用于维持制冷效果，且相比第一制冷阶段减小风力或提高送风发散度，以使冷风气流更加柔和，提高人体舒适感。 In the air conditioner and control method thereof of the embodiment of the present invention, the air conditioner is provided with a "dehumidification heat control mode", which is particularly suitable for activation in high temperature and high humidity environments in summer, such as the summer environment in the southeastern coastal areas of China. In the "dehumidification heat control mode", the air conditioner is divided into three stages of operation, namely the dehumidification stage, the first cooling stage and the second cooling stage. The dehumidification stage is used for dehumidification to rapidly reduce the indoor humidity; the first cooling stage is used for full indoor cooling to make the indoor environment meet human expectations as soon as possible; the second cooling stage is used to maintain the cooling effect, and compared with the first cooling stage, the wind force is reduced or the air supply divergence is increased to make the cold air flow softer and improve human comfort.
本发明实施例满足了高温高湿环境的快速制冷除湿，使人体快速摆脱不舒适感，并且通过智能控温控湿和自动调节，免去了用户反复调节各项参数的麻烦，增强了用户的智能化体验。而且这种智能化的调节还节约了空调能耗，实现了节能减排的目标。The embodiment of the present invention satisfies the requirement of rapid cooling and dehumidification in a high temperature and high humidity environment, allowing the human body to quickly get rid of discomfort, and through intelligent temperature and humidity control and automatic adjustment, it saves the user the trouble of repeatedly adjusting various parameters, thereby enhancing the user's intelligent experience. Moreover, this intelligent adjustment also saves air conditioning energy consumption, achieving the goal of energy saving and emission reduction.
在一些实施例中，可使前述第一制冷阶段的目标温度大于除湿阶段的目标温度。还可使第二制冷阶段的目标温度大于或等于第一制冷阶段的目标温度。例如，使除湿阶段的目标温度为24℃，使第一制冷阶段和第二制冷阶段的目标温度均为26℃。In some embodiments, the target temperature of the first cooling stage may be greater than the target temperature of the dehumidification stage. The target temperature of the second cooling stage may also be greater than or equal to the target temperature of the first cooling stage. For example, the target temperature of the dehumidification stage is 24°C, and the target temperatures of the first cooling stage and the second cooling stage are both 26°C.
本发明实施例如此设置，是因为考虑到除湿阶段的除湿运行实际上也具有一定的制冷效果，因此在第一制冷阶段可适当调高目标温度，以达到节能效果。而第二制冷阶段的作用是保持第一制冷阶段的制冷效果。因此，其目标温度无需低于第一制冷阶段。The embodiment of the present invention is configured in this way because it is considered that the dehumidification operation in the dehumidification stage actually has a certain cooling effect. Therefore, the target temperature can be appropriately increased in the first cooling stage to achieve energy saving effect. The function of the second cooling stage is to maintain the cooling effect of the first cooling stage. Therefore, its target temperature does not need to be lower than that of the first cooling stage.
在一些实施例中，前述的第一切换条件优选为：室内相对湿度小于等于预设湿度。当室内相对湿度小于等于预设湿度时，表明除湿运行已经达到或接近预期效果，可切换至第一制冷阶段。例如，该预设湿度可为80％。将该预设湿度设置地较高，是因为后续的制冷过程中，水蒸气仍然会在蒸发器表面凝结，除湿进程仍将继续，因此可将除湿的目标设计地稍高，无需在除湿阶段便将相对湿度调节至人体最舒适的范围。In some embodiments, the aforementioned first switching condition is preferably: the indoor relative humidity is less than or equal to the preset humidity. When the indoor relative humidity is less than or equal to the preset humidity, it indicates that the dehumidification operation has achieved or is close to the expected effect, and the first cooling stage can be switched. For example, the preset humidity can be 80%. The preset humidity is set higher because in the subsequent cooling process, water vapor will still condense on the evaporator surface, and the dehumidification process will continue. Therefore, the dehumidification target can be designed to be slightly higher, and there is no need to adjust the relative humidity to the most comfortable range for the human body during the dehumidification stage.
空调可包括湿度检测装置90，以用于检测室内相对湿度。具体地，可每隔预设时长获取室内相对湿度的检测值，并判断其是否满足所述第一切换条件。例如每5min检测一次。The air conditioner may include a humidity detection device 90 for detecting indoor relative humidity. Specifically, the detection value of indoor relative humidity may be obtained at preset time intervals to determine whether it meets the first switching condition, for example, once every 5 minutes.
在一些实施例中，前述的第二切换条件为：接收用户进入第二制冷阶段的控制指令。具体地，用户希望空调运行“除湿热控制模式”的第二制冷阶段时，可对遥控器、线控器、空调主机的控制面板或者其他与空调进行无线连接的智能终端设备等控制端进行相应操作，使其向空调的控制器800发出相关指令。控制端可设置有一个专门的键位，例如可命名为“睡眠”、“舒适”等，以供用户发出该指令。In some embodiments, the aforementioned second switching condition is: receiving a control instruction from a user to enter the second cooling stage. Specifically, when the user wants the air conditioner to run the second cooling stage of the "dehumidification heat control mode", the user can perform corresponding operations on the control terminal such as the remote control, wired controller, control panel of the air conditioner host, or other smart terminal devices wirelessly connected to the air conditioner, so that it sends relevant instructions to the air conditioner controller 800. The control terminal can be provided with a special key position, such as "sleep", "comfort", etc., for the user to issue the instruction.
本实施例将用户指令融合入了空调的智能控制，使得空调在自动控制的同时参考了用户的阶段性需求，实现了便利性与人性化的统一。This embodiment integrates user instructions into the intelligent control of the air conditioner, so that the air conditioner takes into account the user's staged needs while automatically controlling, thus achieving the unity of convenience and humanity.
在一些实施例中，当第一制冷阶段运行超过预设时间后，可向用户发出提示，提示用户可选择进入第二制冷阶段。 In some embodiments, when the first cooling stage runs for more than a preset time, a prompt may be issued to the user, prompting the user to choose to enter the second cooling stage.
在一些实施例中，在除湿阶段，控制多个导风板51、52转动至使出风口12的出风面积最大的最大出风位置，如图3，以便实现更快速地除湿和制冷。在第一制冷阶段，控制多个导风板51、52转动至朝前上方导风的上扬导风位置，如图4，以便对室内环境大范围制冷。在第二制冷阶段，控制部分导风板51朝前导风，其他部分导风板52朝下导风的环抱导风位置，使气流更加分散，提高了送风发散度。In some embodiments, in the dehumidification stage, the plurality of air guide plates 51 and 52 are controlled to rotate to the maximum air outlet position that maximizes the air outlet area of the air outlet 12, as shown in FIG3, so as to achieve faster dehumidification and cooling. In the first cooling stage, the plurality of air guide plates 51 and 52 are controlled to rotate to the upward air guide position that guides the air forward and upward, as shown in FIG4, so as to cool the indoor environment over a large range. In the second cooling stage, some air guide plates 51 are controlled to guide the air forward, and other air guide plates 52 are controlled to guide the air downward to the surrounding air guide position, so that the air flow is more dispersed and the air supply divergence is improved.
在一些实施例中，在除湿阶段，控制摆叶组件60保持在使出风流量最大的角度，以便实现更快速地除湿和制冷。在第一制冷阶段，控制摆叶组件60进行左右往复摆风，以便对室内环境大范围制冷。在第二制冷阶段，控制摆叶组件60保持使出风流量最小的角度，以使气流流量最小，从而减小风力。In some embodiments, in the dehumidification stage, the swing blade assembly 60 is controlled to maintain an angle that maximizes the air flow rate, so as to achieve faster dehumidification and cooling. In the first cooling stage, the swing blade assembly 60 is controlled to swing back and forth to cool the indoor environment over a large range. In the second cooling stage, the swing blade assembly 60 is controlled to maintain an angle that minimizes the air flow rate, so as to minimize the air flow rate and reduce the wind force.
在一些实施例中，也可使第二制冷阶段的风机30的转速低于第一制冷阶段，以使风力更小。In some embodiments, the rotation speed of the fan 30 in the second cooling stage may also be lower than that in the first cooling stage to make the wind force smaller.
