随着经济和科学技术的发展，消费者对居住环境的要求越来越高，由此发明了能够在夏天降低室内温度的空调。但单一制冷的空调无法满足冬天取暖的要求，由此，空调又进一步被改进成了既可以制冷又可以制热的冷暖空调，从而可以在寒冷的冬季为消费者带来温暖适宜的室内温度。With the development of economy and science and technology, consumers have higher and higher requirements for the living environment, thus invented the air conditioner that can lower the indoor temperature in summer. However, a single-refrigeration air conditioner cannot meet the heating requirements in winter. As a result, the air conditioner has been further improved into a heating and cooling air conditioner that can both cool and heat, so as to bring consumers a warm and suitable indoor temperature in the cold winter.
相关技术中，无论是单独制冷的空调还是冷暖两用的空调均包括壳体以及设置在壳体内的风机和换热器，壳体的侧面板或者背面板设置有进风口，壳体的前面板设置有出风口，进风口和出风口之间形成风道，风机和换热器设置在风道内。空调在启动后，在风机的作用下，外界环境中的空气从进风口进入壳体内部并与换热器中流动的冷媒换热，经过热交换的空气从出风口送入室内，使得室内温度降低或者升高。In the related art, whether it is a single-cooling air conditioner or a dual-purpose air conditioner, it includes a shell, a fan and a heat exchanger arranged in the shell, the side panel or the back panel of the shell is provided with an air inlet, and the front panel of the shell An air outlet is provided, an air duct is formed between the air inlet and the air outlet, and the fan and the heat exchanger are arranged in the air duct. After the air conditioner is started, under the action of the fan, the air in the external environment enters the shell from the air inlet and exchanges heat with the refrigerant flowing in the heat exchanger. The heat-exchanged air is sent into the room from the air outlet to make the room temperature Decrease or increase.
但是，经过换热器换热的空气，会导致室内相对湿度发生变化，影响用户的舒适度。However, the air passing through the heat exchanger will change the relative humidity in the room and affect the comfort of users.
下面阐述本发明实施例的双贯流空调内机的优选技术方案。The following describes the preferred technical solution of the double tubular air conditioner internal unit of the embodiment of the present invention.
图1为本发明实施例提供的双贯流空调内机的主视图，图2为图1中A-A向的剖视图。如图1和图2所示，本实施例提供一种双贯流空调内机10，其包括壳体1，壳体1具有至少出风部分被隔开的第一风道11和第二风道12，第一风道11和第二风道12内各自设置有单独的换热器2和贯流风机3，换热器2位于风道的进风口与贯流风机3之间，用于交换热量，贯流风机3用于驱动外界环境中的空气从风道的进风口进入风道，并将经换热器2换热后的空气从风道的出风口排出到室内，以实现制冷或制热。空调制热时，热风吹入室内使得室内空气的湿度降低。Fig. 1 is a front view of a double tubular air conditioner internal unit provided by an embodiment of the present invention, and Fig. 2 is a cross-sectional view taken along line A-A in Fig. 1. As shown in Figures 1 and 2, this embodiment provides a dual tubular air-conditioning internal unit 10, which includes a housing 1, and the housing 1 has a first air duct 11 and a second air duct at least partly separated from the air outlet. A separate heat exchanger 2 and a cross-flow fan 3 are provided in the first air passage 11 and the second air passage 12, respectively. The heat exchanger 2 is located between the air inlet of the air passage and the cross-flow fan 3 for Exchange heat, the cross flow fan 3 is used to drive the air in the external environment from the air inlet of the air duct into the air duct, and the air after the heat exchange by the heat exchanger 2 is discharged from the air outlet of the air duct to the room to achieve cooling Or heating. When the air conditioner is heating, hot air blows into the room to reduce the humidity of the indoor air.
具体而言，壳体1内部设置有分离装置4，分离装置4将第一风道11和第二风道12分隔开。其中，可以理解的是，第一风道11的进风口和第二风道12的进风口可以为同一个，或者，第一风道11的进风口和第二风道12的进风口也被分隔开。示意性地，第一风道11的进风口和第二风道12的进风口分别设置在壳体1的后侧壁的左右两侧。Specifically, a separation device 4 is provided inside the housing 1, and the separation device 4 separates the first air passage 11 and the second air passage 12. Among them, it is understandable that the air inlet of the first air duct 11 and the air inlet of the second air duct 12 may be the same, or the air inlet of the first air duct 11 and the air inlet of the second air duct 12 are also Separate. Illustratively, the air inlet of the first air duct 11 and the air inlet of the second air duct 12 are respectively arranged on the left and right sides of the rear side wall of the housing 1.
第一风道11的出风口和第二风道12的出风口可以分别形成在壳体1的左侧壁和右侧壁上，由此，从第一风道11排出的空气和从第二风道12排出的空气分别吹向空调内机的左侧和右侧，也就是说，换热后的风可以吹向室内的不同区域，使得位于室内不同区域的用户均能感受到风，使得用户感觉舒适。当然，第一风道11的出风口和第二风道12的出风口也可以分别形成在壳体1的前侧壁的左右两侧。The air outlet of the first air duct 11 and the air outlet of the second air duct 12 may be respectively formed on the left side wall and the right side wall of the housing 1, thereby, the air discharged from the first air duct 11 and the air discharged from the second air duct 11 The air discharged from the air duct 12 is blown to the left and right sides of the internal unit of the air conditioner. The user feels comfortable. Of course, the air outlet of the first air duct 11 and the air outlet of the second air duct 12 may also be formed on the left and right sides of the front side wall of the housing 1 respectively.
参照图2，第一风道11和第二风道12内各自设置有单独的加湿模块5，加湿模块5用于增加流过风道的空气的湿度。由此，利用加湿模块5可以提高排入室内的空气的湿度，改善了因空调制热而导致室内空气干燥的问题，提高了用户的舒适度。而且，当从第一风道11的出风口和第二风道12的出风口排出的空气吹向室内的不同区域时，可以使得位于室内不同区域的用户均能感受到具有一定湿度的风，有利于改善用户的舒适度体验。2, the first air duct 11 and the second air duct 12 are each provided with a separate humidification module 5, and the humidification module 5 is used to increase the humidity of the air flowing through the air duct. As a result, the humidification module 5 can increase the humidity of the air discharged into the room, improve the problem of dry indoor air caused by the heating of the air conditioner, and improve the comfort of the user. Moreover, when the air discharged from the air outlet of the first air duct 11 and the air outlet of the second air duct 12 is blown to different areas of the room, users in different areas of the room can feel the wind with a certain humidity. Conducive to improving the user's comfort experience.
本实施例中，第一风道11和第二风道12内各自设置的加湿模块5被配置成分别控制或者是联动控制。由此，当两个加湿模块5被配置为分别控制时，空调内机可以灵活的往室内排入具有一定湿度的风，进而可以满 足用户在不同场景下对湿度的要求；当两个加湿模块5被配置为联动控制时，无需对两个加湿模块5分别进行控制，操作简单，且能够均衡的改变室内空气的湿度。In this embodiment, the humidification modules 5 respectively provided in the first air duct 11 and the second air duct 12 are configured to be controlled separately or in linkage control. Therefore, when the two humidification modules 5 are configured to be controlled separately, the air conditioner internal unit can flexibly discharge air with a certain humidity into the room, thereby meeting the user's requirements for humidity in different scenarios; when the two humidification modules When 5 is configured for linkage control, there is no need to control the two humidification modules 5 separately, the operation is simple, and the humidity of the indoor air can be changed in a balanced manner.
当第一风道11和第二风道12内各自设置的加湿模块5被配置成分别控制时，两个加湿模块5的控制策略可以不同。When the humidification modules 5 respectively provided in the first air duct 11 and the second air duct 12 are configured to be controlled separately, the control strategies of the two humidification modules 5 may be different.
在一个示例中，第一风道11的加湿模块5被配置成与第二风道12的加湿模块5的运行状态不同。也就是说，两个加湿模块5中的一个工作，以提高流过其所在风道的空气湿度，另一个停止工作。由此，当从第一风道11的出风口和第二风道12的出风口排出的空气分别吹向室内的第一区域和第二区域时，采用上述控制方式可以使具有一定湿度的空气单独吹向第一区域或者单独吹向第二区域，以针对性的调节某一个区域的空气湿度，以满足该区域用户的需求。In an example, the humidification module 5 of the first air duct 11 is configured to have a different operating state from the humidification module 5 of the second air duct 12. In other words, one of the two humidification modules 5 works to increase the humidity of the air flowing through the air duct where it is located, and the other stops working. Therefore, when the air discharged from the air outlet of the first air duct 11 and the air outlet of the second air duct 12 are respectively blown to the first area and the second area of the room, the above-mentioned control method can make the air with a certain humidity Blow separately to the first area or separately to the second area to specifically adjust the air humidity in a certain area to meet the needs of users in that area.
示意性地，位于第一区域中的用户要求室内空气具有一定的湿度，位于第二区域中的用户(例如具有风湿病的患者、婴幼儿等)要求室内空气的湿度低或者室内空气为干燥时，则配置第一风道11中的加湿模块5进行加湿，配置第二风道12中的加湿模块5停止加湿，进而分别满足不同区域的用户的要求。Illustratively, users located in the first area require indoor air to have a certain humidity, and users located in the second area (for example, patients with rheumatism, infants, etc.) require low humidity in the indoor air or when the indoor air is dry , The humidification module 5 in the first air duct 11 is configured for humidification, and the humidification module 5 in the second air duct 12 is configured to stop humidification, so as to meet the requirements of users in different regions.
在另一个示例中，第一风道11的加湿模块5被配置成与第二风道12的加湿模块5具有不同的加湿效率。也就是说，第一风道11中的加湿模块5对第一风道11的空气的加湿量和第二风道12中的加湿模块5对第二风道12的空气的加湿量不同。由此，可以满足位于不同区域的用户对不同湿度的要求。In another example, the humidification module 5 of the first air duct 11 is configured to have a different humidification efficiency from the humidification module 5 of the second air duct 12. That is, the humidification amount of the humidification module 5 in the first air passage 11 to the air of the first air passage 11 and the humidification amount of the humidification module 5 in the second air passage 12 to the air of the second air passage 12 are different. As a result, the requirements of users in different areas for different humidity can be met.
例如，位于第一区域中的用户(例如年轻人)对空气湿度的要求为60％，位于第二区域的用户(例如老人)对空气湿度的要求为20％时，则配置第一风道11中的加湿模块5对空气的加湿效率较第二风道12中的加湿模块5对空气的加湿效率高。For example, when the user (for example, young people) in the first area has a requirement of 60% for air humidity, and the user (for example, the elderly) in the second area has a requirement for air humidity of 20%, the first air duct 11 is configured. The humidification module 5 in the second air duct 12 has a higher humidification efficiency for the air than the humidification module 5 in the second air duct 12 has a higher humidification efficiency for the air.
具体来说，加湿模块5可以包括水容器、导气管和超声波雾化片，水容器用于盛装水，超声波雾化片设置在水容器内，用于使水容器内的水产生水汽，水容器上设置有送气口，导气管的进气端与送气口连通，导气管的出气端与风道连通。空调内机工作时，超声波雾化片运行，使得水容器 内的水产生水汽，水汽依次经送气口、导气管的进气端进入导气管的内部，然后从导气管的出气端流至风道内，与风道内的空气汇合，以使风道内的空气的湿度增加。Specifically, the humidification module 5 may include a water container, an air duct, and an ultrasonic atomizing sheet. The water container is used to contain water, and the ultrasonic atomizing sheet is arranged in the water container to generate vapor from the water in the water container. An air supply port is arranged on the upper part, the air inlet end of the air guide tube is connected with the air supply port, and the air outlet end of the air guide tube is connected with the air duct. When the internal unit of the air conditioner is working, the ultrasonic atomizing film operates to make the water in the water container produce water vapor. The water vapor enters the air duct through the air supply port and the air inlet end of the air duct in turn, and then flows from the air outlet end of the air duct to the air duct. , It merges with the air in the air duct to increase the humidity of the air in the air duct.
图3为本发明实施例提供的双贯流空调内机中加湿模块的主视图，图4为本发明实施例提供的双贯流空调内机中加湿模块的结构示意图。或者，如图3和图4所示，加湿模块5还可以包括水容器51、水泵52、给水管53和加湿件54，水容器51用于盛装水，水泵52的进水口与水容器51连通，水泵52的出水管与给水管53的一端连通，给水管53的另一端与加湿件54连通，加湿件54被构置为能够供空气通过。由此，与上一实现方式相比，有利于避免形成的水汽在壳体1内流动而影响其他部件的电气性能。Fig. 3 is a front view of the humidifying module in the double-through air conditioner internal unit provided by an embodiment of the present invention, and Fig. 4 is a schematic structural diagram of the humidifying module in the double-through flow air conditioner internal unit provided by an embodiment of the present invention. Or, as shown in FIGS. 3 and 4, the humidification module 5 may also include a water container 51, a water pump 52, a water supply pipe 53, and a humidification member 54, where the water container 51 is used to contain water, and the water inlet of the water pump 52 is in communication with the water container 51 The outlet pipe of the water pump 52 communicates with one end of the water supply pipe 53, and the other end of the water supply pipe 53 communicates with the humidifying element 54 which is configured to allow air to pass through. Therefore, compared with the previous implementation, it is beneficial to prevent the formed water vapor from flowing in the housing 1 and affecting the electrical performance of other components.
在本实施例中，双贯流空调内机10还包括控制器，控制器与加湿模块5的水泵52电连接，控制器用于控制两个风道中加湿模块5的水泵52的功率，从而实现联动控制或者分别控制。具体的，控制器控制两个风道内的加湿模块5的水泵52的功率不同，从而使两个加湿模块5具有不同的加湿效率。In this embodiment, the dual tubular air conditioner internal unit 10 further includes a controller, which is electrically connected to the water pump 52 of the humidification module 5. The controller is used to control the power of the water pump 52 of the humidification module 5 in the two air ducts, so as to achieve linkage Control or separate control. Specifically, the controller controls the powers of the water pumps 52 of the humidification modules 5 in the two air ducts to be different, so that the two humidification modules 5 have different humidification efficiencies.
值得说明的是，设置在第一风道11的加湿模块5和设置在第二风道12的加湿模块5可以共用一个水容器51。由此，减少了水容器51的使用数量，使得空调内机的整体更简单。其中，水容器51可以为水箱，水箱可以安装在壳体1的底部或其他位置，只要从壳体1外部能够注入水到水箱内即可，以免水箱的水消耗完毕而无法为加湿件54补水，确保加湿件54可以有效工作。在其他示例中，水容器51也可以为接水盘，接水盘设置在换热器2的底部，接水盘用于承接换热器2上的冷凝水。由此，可以循环利用冷凝水，节约资源。It is worth noting that the humidification module 5 provided in the first air duct 11 and the humidification module 5 provided in the second air duct 12 may share a water container 51. As a result, the number of water containers 51 used is reduced, and the overall air conditioner internal unit is simpler. Among them, the water container 51 can be a water tank, which can be installed at the bottom of the casing 1 or other positions, as long as water can be injected into the water tank from the outside of the casing 1, so as to prevent the water in the water tank from being consumed and the humidifying element 54 cannot be refilled. , To ensure that the humidifier 54 can work effectively. In other examples, the water container 51 may also be a water receiving pan, which is arranged at the bottom of the heat exchanger 2, and the water receiving pan is used to receive the condensed water on the heat exchanger 2. As a result, condensed water can be recycled and resources can be saved.
加湿件54包括支承架和连接在支承架上的吸水部，吸水部与给水管53的另一端连通，以使通过吸水部的空气的湿度增加。其中，支承架可以由金属材料制作而成，也可以由塑料材料制作而成，用于支撑吸水部，以提高加湿件54的强度。吸水部可以为海绵块，海绵块上形成有插孔，给水管53插设在插孔内，将水导入至海绵块内以使其湿润。这里，吸水部和支承架可以通过粘接的方式连接，也可以通过插接等可拆卸的方式连接， 本实施例对此不做限制。The humidifying element 54 includes a support frame and a water absorption part connected to the support frame, and the water absorption part communicates with the other end of the water supply pipe 53 to increase the humidity of the air passing through the water absorption part. Wherein, the supporting frame can be made of metal material or plastic material, and is used to support the water absorption part so as to improve the strength of the humidifying member 54. The water absorbing part may be a sponge block, and a socket is formed on the sponge block, and the water supply pipe 53 is inserted into the socket to introduce water into the sponge block to make it wet. Here, the water absorption part and the support frame can be connected by bonding, or can be connected by detachable means such as plug-in connection, which is not limited in this embodiment.
其中，加湿件54可以安装于贯流风机3和风道的出风口之间。空调启动时，贯流风机3运转，外界环境中的空气在贯流风机3的作用下进入第一风道11和第二风道12，先经换热器2换热后，再经加湿模块5加湿。或者，如图2所示，加湿件54还可以安装于风道的进风口和换热器2之间。本示例中，外界环境中的空气先经加湿模块5进行加湿，再与换热器2进行热交换。由此，换热器2、贯流风机3和风道的出风口之间的结构通常比较紧凑，如此设置，加湿件54的安装空间大，便于安装。Wherein, the humidifying element 54 may be installed between the cross flow fan 3 and the air outlet of the air duct. When the air conditioner starts, the cross flow fan 3 runs, and the air in the external environment enters the first air duct 11 and the second air duct 12 under the action of the cross flow fan 3, first passes through the heat exchanger 2 to exchange heat, and then passes through the humidification module 5 Humidification. Or, as shown in FIG. 2, the humidifying element 54 can also be installed between the air inlet of the air duct and the heat exchanger 2. In this example, the air in the external environment is first humidified by the humidification module 5, and then heat exchange with the heat exchanger 2 is performed. Therefore, the structure between the heat exchanger 2, the cross-flow fan 3 and the air outlet of the air duct is usually relatively compact. With this arrangement, the installation space of the humidifying element 54 is large, which is convenient for installation.
而且，加湿件54靠近风道的进风口设置，以便于拆卸加湿件54，进而对加湿件54进行维修和更换，以使加湿件54可以有效的工作。具体的，壳体1的后侧壁上可拆卸的连接有进风格栅，加湿件54可拆卸的连接在进风格栅朝向壳体1内部的内侧壁上。需要更换时，先将进风格栅从壳体1上拆卸下来，再分离加湿件54和进风格栅。Moreover, the humidifying element 54 is arranged close to the air inlet of the air duct, so that the humidifying element 54 can be disassembled, and then the humidifying element 54 can be repaired and replaced, so that the humidifying element 54 can work effectively. Specifically, an air inlet grille is detachably connected to the rear side wall of the casing 1, and the humidifying element 54 is detachably connected to the inner side wall of the air inlet grille facing the inside of the casing 1. When it needs to be replaced, first remove the inlet grille from the housing 1, and then separate the humidifying element 54 and the inlet grille.
此外，控制器还可以与第一风道11和第二风道12内各自设置的贯流风机3电连接，用于控制贯流风机3的功率。由此，控制器通过控制贯流风机3的功率，可以控制风道的送风风量，进而可以控制加湿速率。In addition, the controller may also be electrically connected to the cross flow fan 3 provided in the first air duct 11 and the second air duct 12 to control the power of the cross flow fan 3. Therefore, the controller can control the air flow of the air duct by controlling the power of the cross flow fan 3, and thus can control the humidification rate.
图5为本发明实施例提供的双贯流空调内机的第一风道和第二风道中的贯流风机具有不同运行功率的工作原理图。控制器对两个贯流风机3的控制策略可以分为以下几种情形：第一种是控制器控制第一风道11内的贯流风机3和第二风道12内的贯流风机3的运行状态不同，以使其中一个贯流风机3停止工作，从而使具有一定湿度的空气单独吹向第一区域或者单独吹向第二区域；第二种是控制器控制第一风道11内的贯流风机3和第二风道12内的贯流风机3具有相同的运行功率，以同时加湿第一区域和第二区域，且使第一区域和第二区域的湿度相同；如图5所示，第三种是控制器控制第一风道11内的贯流风机3和第二风道12内的贯流风机3具有不同的运行功率，使得送入第一区域和第二区域的湿空气的气量不同，以使第一区域和第二区域的加湿量不同，从而满足位于不同区域的用户对不同湿度的要求。Fig. 5 is a working principle diagram of the cross-flow fans having different operating powers in the first air duct and the second air duct of the internal unit of the dual-tubular flow air conditioner provided by the embodiment of the present invention. The controller's control strategy for the two cross flow fans 3 can be divided into the following situations: The first is that the controller controls the cross flow fan 3 in the first air duct 11 and the cross flow fan 3 in the second air duct 12 The operating state is different, so that one of the cross-flow fans 3 stops working, so that the air with a certain humidity is blown to the first area alone or to the second area alone; the second is that the controller controls the first air duct 11 The cross flow fan 3 and the cross flow fan 3 in the second air duct 12 have the same operating power to humidify the first area and the second area at the same time, and make the humidity of the first area and the second area the same; as shown in Figure 5 As shown, the third type is that the controller controls the cross flow fan 3 in the first air duct 11 and the cross flow fan 3 in the second air duct 12 to have different operating powers, so that the The air volume of the humid air is different, so that the humidification volume of the first area and the second area are different, so as to meet the requirements of users in different areas for different humidity.
此外，控制器被配置为在第一风道11和第二风道12各自设置的贯流风机3运行时控制该风道内的加湿模块5的水泵52运转第一预设时间， 之后控制该水泵52停止运转。由此，风道内的贯流风机3启动的同时，水泵52在预设时间段内持续向加湿件54供水，以使加湿件54湿润，继而使流经加湿件54的空气的湿度增加。In addition, the controller is configured to control the water pump 52 of the humidification module 5 in the air duct to operate for a first preset time when the cross-flow fan 3 provided in each of the first air duct 11 and the second air duct 12 is operating, and then to control the water pump 52 stopped operation. Thus, while the cross flow fan 3 in the air duct is activated, the water pump 52 continues to supply water to the humidifying element 54 for a preset period of time, so that the humidifying element 54 is humidified, and then the humidity of the air flowing through the humidifying element 54 is increased.
这里，第一预设时间可以由设计人员根据经验和实际需要进行自由设定，本实施例对此不做限制。较佳地，第一预设时间可以为水泵52向加湿件54供水并使其达到饱和状态所需的时间。由此，无需频繁的向加湿件54供水。Here, the first preset time can be freely set by the designer according to experience and actual needs, which is not limited in this embodiment. Preferably, the first preset time may be the time required for the water pump 52 to supply water to the humidifying element 54 and make it reach a saturated state. Therefore, there is no need to frequently supply water to the humidifying element 54.
进一步地，第一风道11和第二风道12的进风口设置有湿度传感器，控制器与湿度传感器电连接，控制器用于在水泵52停止运转时控制湿度传感器检测外界环境中的空气湿度，并在空气湿度未达到预设湿度时控制水泵52运转，或者，在空气湿度达到或者超过预设湿度时控制水泵52停止运转第二预设时间。其中，预设湿度可以由用户设定，以使室内空气湿度满足用户的需求；第二预设时间也可以由设计人员根据经验和实际需要进行自由设定。Further, the air inlets of the first air duct 11 and the second air duct 12 are provided with humidity sensors, and the controller is electrically connected to the humidity sensor. The controller is used to control the humidity sensor to detect the air humidity in the external environment when the water pump 52 stops running, And when the air humidity does not reach the preset humidity, the water pump 52 is controlled to operate, or when the air humidity reaches or exceeds the preset humidity, the water pump 52 is controlled to stop operating for a second preset time. Among them, the preset humidity can be set by the user, so that the indoor air humidity meets the needs of the user; the second preset time can also be freely set by the designer according to experience and actual needs.
通过上述设置，水泵52运行第一预设时间后，检测室内空气的湿度，若室内空气湿度未达到预设湿度，使水泵52继续向加湿件54供水，继而提高流经加湿件54的空气湿度，使其达到用户满意的预设湿度；若室内空气湿度超过预设湿度，使水泵52停止向加湿件54供水，以避免空气湿度持续增加，继而使得室内空气湿度逐渐降低以达到用户满意的预设湿度。总的来说，双贯流空调内机10检测到室内空气的湿度不符合用户的要求时，自动控制加湿模块5调节其加湿效率，以使室内空气湿度达到用户满意的湿度，以提高用户的舒适度体验，并且实现了智能化控制。With the above settings, after the water pump 52 runs for the first preset time, the humidity of the indoor air is detected. If the indoor air humidity does not reach the preset humidity, the water pump 52 continues to supply water to the humidifying element 54 and then increasing the humidity of the air flowing through the humidifying element 54 If the indoor air humidity exceeds the preset humidity, the water pump 52 will stop supplying water to the humidifying element 54 to prevent the air humidity from increasing continuously, and then the indoor air humidity will gradually decrease to achieve the user’s satisfaction. Set humidity. In general, when the indoor air humidity of the double tubular air conditioner 10 detects that the humidity of the indoor air does not meet the requirements of the user, it automatically controls the humidification module 5 to adjust its humidification efficiency, so that the indoor air humidity reaches the user's satisfactory humidity, so as to improve the user's Comfortable experience and intelligent control is realized.
当第一风道11和第二风道12各自的出风口吹出的风吹向室内不同的区域时，第一风道11和第二风道12的进风部分可以被分隔开，第一风道11和第二风道12的进风口处各自设置有单独的湿度传感器。控制器用于在与第一风道11内的加湿件54配对的水泵52停止运转时控制第一风道11内的湿度传感器检测外界环境中的空气湿度，并在该空气湿度未达到第一预设湿度时控制水泵52运转，或者，在空气湿度达到或者超过第一预设湿度时控制水泵52停止运转第二预设时间。控制器用于在与第二风道12内的加湿件54配对的水泵52停止运转时控制第二风道12内的湿度传 感器检测外界环境中的空气湿度，并在该空气湿度未达到第二预设湿度时控制水泵52运转，或者，在空气湿度达到或者超过第二预设湿度时控制水泵52停止运转第二预设时间。When the wind blown from the respective outlets of the first air duct 11 and the second air duct 12 is blown to different areas in the room, the air inlet part of the first air duct 11 and the second air duct 12 can be separated, and the first Separate humidity sensors are provided at the air inlets of the air duct 11 and the second air duct 12 respectively. The controller is used to control the humidity sensor in the first air duct 11 to detect the air humidity in the external environment when the water pump 52 paired with the humidifying element 54 in the first air duct 11 stops operating, and when the air humidity does not reach the first preset When the humidity is set, the water pump 52 is controlled to operate, or when the air humidity reaches or exceeds a first preset humidity, the water pump 52 is controlled to stop operating for a second preset time. The controller is used to control the humidity sensor in the second air duct 12 to detect the air humidity in the external environment when the water pump 52 paired with the humidifier 54 in the second air duct 12 stops operating, and when the air humidity does not reach the second preset When the humidity is set, the water pump 52 is controlled to operate, or when the air humidity reaches or exceeds a second preset humidity, the water pump 52 is controlled to stop operating for a second preset time.
其中，第一预设湿度为位于第一区域内的用户满意的空气湿度，第二预设湿度为位于第二区域内的用户满意的空气湿度。这样设置，使得第一区域和第二区域的空气湿度分别达到该区域内用户的需求，以满足不同区域内用户对不同湿度的需求。The first preset humidity is the air humidity that is satisfactory to the user in the first area, and the second preset humidity is the air humidity that is satisfactory to the user in the second area. In this way, the air humidity in the first area and the second area respectively meet the requirements of users in the area, so as to meet the requirements of users in different areas for different humidity.
当然，在本发明的一些示例中，第一风道11和第二风道12的出风口处各自设置有单独的导风板6。由此，导风板6可以用于启闭风道的出风口，还可以用于引导从出风口流出的空气的流向。Of course, in some examples of the present invention, a separate wind deflector 6 is provided at the air outlets of the first air duct 11 and the second air duct 12 respectively. Therefore, the wind deflector 6 can be used to open and close the air outlet of the air duct, and can also be used to guide the flow direction of the air flowing out of the air outlet.
其中，第一风道11和第二风道12的出风口处各自设置的导风板6被配置为分别控制或者是联动控制。当两个导风板6被配置为联动控制时，可以同时打开或同时关闭第一风道11的出风口和第二风道12的出风口，从而无需对两个导风板6分别进行控制，操作简便。当两个导风板6被配置为分别控制时，通过单独控制两个导风板6可以单独控制第一风道11的出风口和/或第二风道12的出风口启闭，继而可以单独加湿第一区域和/或第二区域，以使空调内机适用于各种场景下。Wherein, the air guide plates 6 respectively provided at the air outlets of the first air duct 11 and the second air duct 12 are configured to be controlled separately or in linkage control. When the two air deflectors 6 are configured for linkage control, the air outlet of the first air duct 11 and the air outlet of the second air duct 12 can be opened or closed at the same time, so that there is no need to separately control the two air deflectors 6 , Easy to operate. When the two air deflectors 6 are configured to be controlled separately, the air outlet of the first air duct 11 and/or the air outlet of the second air duct 12 can be opened and closed separately by controlling the two air deflectors 6 separately, and then Separately humidify the first zone and/or the second zone, so that the internal air conditioner is suitable for various scenarios.
双贯流空调内机10还可以包括驱动器，驱动器用于可控的驱动导风板6转动以启闭风道的出风口。驱动器可以设置为一个，通过同一个驱动器同时控制第一风道11和第二风道12各自设置的导风板6，以实现联动控制。驱动器可以设置为两个，两个驱动器分别驱动第一风道11内的导风板6和第二风道12内的导风板6运动，以实现分别控制。其中，驱动器可以是电机、气缸、油缸等。The dual tubular air conditioner internal unit 10 may also include a driver, which is used to controllably drive the air deflector 6 to rotate to open and close the air outlet of the air duct. The number of drivers can be set to one, and the same driver can simultaneously control the respective air guide plates 6 of the first air duct 11 and the second air duct 12 to achieve linkage control. There may be two drivers, and the two drivers respectively drive the air deflector 6 in the first air duct 11 and the air deflector 6 in the second air duct 12 to move, so as to realize separate control. Among them, the driver can be a motor, an air cylinder, an oil cylinder, and so on.
具体而言，导风板6通过转动轴与壳体1可转动连接，驱动器与转动轴传动连接，驱动器驱动导风板6绕转动轴转动以启闭出风口。可选地，转动轴设置在导风板6的一端。由此，当第一风道11和第二风道12的出风口处各自设置的导风板6被配置为分别控制时，通过调节两个转动轴的转动角度可以调节导风板6的打开角度，继而可以调节风道的出风口的启闭程度，可以使送入第一区域和第二区域的湿空气的气量不同，以满足位于不同区域的用户对不同湿度的要求。Specifically, the wind deflector 6 is rotatably connected with the housing 1 through a rotating shaft, a driver is drivingly connected with the rotating shaft, and the driver drives the wind deflector 6 to rotate around the rotating shaft to open and close the air outlet. Optionally, the rotating shaft is arranged at one end of the wind deflector 6. Therefore, when the wind deflectors 6 respectively provided at the air outlets of the first air duct 11 and the second air duct 12 are configured to be controlled separately, the opening of the wind deflectors 6 can be adjusted by adjusting the rotation angles of the two rotating shafts. The angle can then adjust the opening and closing degree of the air outlet of the air duct, so that the amount of humid air sent into the first area and the second area can be different, so as to meet the requirements of users in different areas for different humidity.
较佳地，转动轴设置在导风板6的中部。由此，当第一风道11和第二风道12的出风口处各自设置的导风板6被配置为分别控制时，通过控制转动轴的转动角度不仅可以调节风道的出风口的启闭程度，还可以调节风道的出风口的送风区域，继而满足用户对不同的送风区域的需求。Preferably, the rotating shaft is arranged in the middle of the wind deflector 6. Therefore, when the air guide plates 6 respectively provided at the air outlets of the first air duct 11 and the second air duct 12 are configured to be controlled separately, not only the opening of the air outlet of the air duct can be adjusted by controlling the rotation angle of the rotating shaft. The degree of closure can also adjust the air supply area of the air outlet of the air duct, and then meet the needs of users for different air supply areas.
当然，在一些示例中，导风板6还可以为摆叶，用户通过拨动摆叶可以改变导风板6的角度，进而可以改变出风口的送风区域和出风口的启闭程度。Of course, in some examples, the wind deflector 6 may also be a swing blade, and the user can change the angle of the wind deflector 6 by flipping the swing blade, thereby changing the air supply area of the air outlet and the degree of opening and closing of the air outlet.
