After the air-conditioning air supply device is used in an air conditioner, the air intake amount of the air conditioner can be increased, the indoor air flow can be accelerated, and Improve the softness of air conditioning and improve user comfort experience. However, since the air-conditioning fan blows air from the bottom to the top, the heat exchange wind is uneven in the circumferential direction when entering the annular air outlet duct, so that the air volume at the lower end of the annular air duct is large, and the air volume on the left and right sides is small, and further The wind sent by the air-conditioning air supply device is unevenly distributed in the entire circumferential direction, which affects the user's comfort effect.

下面结合附图和具体实施方式对本发明的技术方案作进一歩详细的说明。 首先， 对该具体实施方式中涉及到的技术术语作一简要说明： 下述在提到 每个结构件的前端或后端时， 是以结构件正常使用状态下相对于使用者的位置 来定义的； 对于多个结构件的排列位置进行前或后的描述时， 也是以多个结构 件构成的装置在正常使用状态下相对于使用者的位置所做的定义。 下述的热交 换风是指来自空调内部、 经热交换器热交换后的风； 非热交换风是指来自空调 所处环境空间的风， 是相对于热交换风而言、 不是直接来自于热交换器的部分 风； 混合风是指热交换风与非热交换风混合形成的风。 下述的环， 是指环绕形 成的封闭结构， 并不局限于圆环。 The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. First, a brief description of the technical terms involved in the specific embodiment is given. The following refers to the front end or the rear end of each structural member, which is defined relative to the position of the user in the normal use state of the structural member. For the description of the arrangement position of a plurality of structural members before or after, it is also a definition of the position of the device composed of a plurality of structural members relative to the user in a normal use state. The following heat exchange wind refers to the wind from the inside of the air conditioner and after heat exchange by the heat exchanger; the non-heat exchange wind refers to the wind from the environmental space where the air conditioner is located, and is not directly from the heat exchange wind. Partial wind of the heat exchanger; mixed wind refers to the wind formed by the combination of heat exchange wind and non-heat exchange wind. The ring below refers to the surrounding shape The closed structure is not limited to a ring.
然后， 简要说明本发明的设计思路： 对于能够将空调热交换器热交换风及 外部非热交换风形成混合风而送出的空调送风装置来说，虽然能够增大送风量、 保证出风温度的适宜， 但是， 由于空调内的风扇位于下方， 热交换器交换后的 热交换风自下而上送风， 使得在空调中放置上这样的空调送风装置之后， 热交 换风在风扇的吹动下大多从空调送风装置下部进入空调送风装置中， 而左右两 侧及上部进风量相对较少， 使得空调送风装置在周向方向上所送出的风不够均 匀。 为解决该问题， 可在空调送风装置的环形热交换风风道中设置对来自空调 热交换器、 并进入该热交换风风道的热交换风进行分配、 尤其是进行均匀分配 的气流分配组件使得热交换风在周向方向上均匀进入热交换风风道中， 从而提 高空调送风装置的送风均匀性。  Then, the design idea of the present invention will be briefly described. The air-conditioning air blower that can send the mixed air of the air-conditioning heat exchanger heat exchange air and the external non-heat exchange air can increase the air supply amount and ensure the air output. The temperature is suitable, however, since the fan in the air conditioner is located below, the heat exchanged air after the exchange of the heat exchanger is blown from the bottom up, so that after the air conditioner is placed in the air conditioner, the heat exchange wind is in the fan. Most of the blown air enters the air-conditioning air supply device from the lower part of the air-conditioning air supply device, and the air intake amount on the left and right sides and the upper portion is relatively small, so that the air sent by the air-conditioning air supply device in the circumferential direction is not uniform enough. In order to solve this problem, an air distribution module for distributing, in particular uniformly distributing, heat exchange air from the air conditioning heat exchanger and entering the heat exchange air duct may be provided in the annular heat exchange air duct of the air conditioning air blowing device. The heat exchange wind is uniformly introduced into the heat exchange air duct in the circumferential direction, thereby improving the air supply uniformity of the air conditioner air blowing device.
请参考图 1， 该图 1所示为具有本发明空调送风装置的空调一个实施例的 结构示意图。  Referring to Fig. 1, Fig. 1 is a schematic view showing the structure of an air conditioner having an air-conditioning air supply device of the present invention.

The structure of the air-conditioning air supply device 10 is shown in Fig. 2 and Fig. 3.
如图 2的立体图及图 3的主视结构图所示意， 同时结合图 1所示意， 该实 施例中的空调送风装置 10包括有环形罩体 101，环形罩体 101中间形成有贯通 整个环形罩体 101的贯通风道（图中未标注）。环形罩体 101的前开口形成混合 风出口 1016， 其后开口形成非热交换风进口 1017。在环形罩体 101的壁上、具 体来说是在环形罩体 101壁的后端开设有连续的环形热交换风主风道 1011，空 调本体 1的内部风道 15通过该环形热交换风主风道 1011与贯通风道相连通。 为稳定空气流动、 同时便于引导空气沿指定方向流动， 在环形热交换风主 风道 1011上设有一个连续的环形导流片 1012，环形导流片 1012将环形热交换 风主风道 1011分割为两个连通内部风道 15和贯通风道的连续型环形热交换风 分风道 1013。 在环形导流片 1012上设置有向由该环形导流片所形成的内、 外 两个环形热交换风分风道 1013中延伸的气流分配组件 18。 而且， 为方便加工， 气流分配组件 18优选与其所在的环形导流片 1012—体成型。 2 is a schematic view of the front view of FIG. 2 and FIG. 3, and the air-conditioning air supply device 10 of the embodiment includes an annular cover 101, and the annular cover 101 is formed with a whole ring in the middle. The through air passage of the cover 101 (not shown). The front opening of the annular shroud 101 forms a mixed air outlet 1016, the rear opening of which forms a non-heat exchanged air inlet 1017. A continuous annular heat exchange air main duct 1011 is opened on the wall of the annular cover 101, specifically at the rear end of the wall of the annular cover 101, The inner duct 15 of the adjustment body 1 communicates with the through duct through the annular heat exchange air main duct 1011. In order to stabilize the air flow while facilitating the flow of the air in a specified direction, a continuous annular baffle 1012 is provided on the annular heat exchange air main duct 1011, and the annular baffle 1012 divides the annular heat exchange wind main duct 1011. It is a continuous annular heat exchange air separation duct 1013 that connects the inner duct 15 and the through duct. An air distribution assembly 18 extending into the inner and outer annular heat exchange air dividing ducts 1013 formed by the annular deflector is disposed on the annular deflector 1012. Moreover, to facilitate processing, the air distribution assembly 18 is preferably integrally formed with the annular baffle 1012 in which it is located.
在将空调送风装置 10装配到空调中时， 环形罩体 101的混合风出口 1016 及非热交换风进口 1017分别与前面板 11上的混合风出口 111及后背板 12上的 非热交换风进口 121对应封闭连接。  When the air conditioning air blower 10 is assembled into the air conditioner, the mixed air outlet 1016 of the annular cover 101 and the non-heat exchange air inlet 1017 are non-heat exchanged with the mixed air outlet 111 and the rear back panel 12 on the front panel 11, respectively. The air inlet 121 corresponds to a closed connection.
在空调中采用上述结构的空调送风装置 10 之后， 空调运行时， 室内风进 入空调壳体内部， 在离心风机 17的作用下， 加速吹向蒸发器 16进行热交换， 热交换后的热交换风从内部风道 15吹向空调送风装置 10。 热交换风在气流分 配组件 18的分配下， 沿周向方向均匀地进入各环形热交换风分风道 1013内， 再经环形热交换风分风道 1013进入贯通风道， 进而经贯通风道从前面板 11上 的混合风出口 111吹出。 从环形热交换风风道吹出的热交换风风速变大， 从而 使得相应环形导流片表面压力减小而在贯通风道内形成负压， 空调外部的室内 风在负压的作用下，将从后背板 12上的非热交换风进口 121进入贯通风道，并 与环形热交换风分风道 1013吹出的热交换风形成混合风后一起送出到室内。这 样的混合空气较为柔和， 吹到用户身上会感觉更加舒适， 提高了用户舒适性体 验效果。同时，利用空气送风装置 10所产生的负压作用吸入部分外部未热交换 的空气参与到空调最后的出风中， 增大了空调的整体进风量， 加快了室内空气 的流动， 进一歩提高了室内空气的整体均匀性。  When the air-conditioning air blower 10 of the above configuration is used in the air conditioner, the indoor air enters the air-conditioning case during the air-conditioning operation, and the air blown to the evaporator 16 is accelerated by the centrifugal fan 17, and the heat exchange after heat exchange is performed. The wind is blown from the internal duct 15 to the air-conditioning air blower 10. The heat exchange air is uniformly distributed into the annular heat exchange air distribution ducts 1013 in the circumferential direction under the distribution of the air distribution unit 18, and then enters the through air passages through the annular heat exchange air separation ducts 1013, and then passes through the through air passages. It is blown out from the mixed air outlet 111 on the front panel 11. The heat exchange wind speed blown from the annular heat exchange air duct becomes large, so that the surface pressure of the corresponding annular baffle is reduced and a negative pressure is formed in the through air passage, and the indoor air outside the air conditioner is under the action of the negative pressure The non-heat exchange air inlet 121 on the back plate 12 enters the through air passage, and is mixed with the heat exchange air blown by the annular heat exchange air separation duct 1013, and then sent out to the room. This kind of mixed air is softer and will feel more comfortable when it is blown to the user, which improves the user's comfort experience. At the same time, the negative air pressure generated by the air blowing device 10 is used to inhale the air that is not heat exchanged outside the air to participate in the final air outlet of the air conditioner, thereby increasing the overall air intake of the air conditioner, accelerating the flow of the indoor air, and improving the indoor air. The overall uniformity of indoor air.
再结合图 3的主视结构示意图所示意，该实施例环形热交换风分风道 1013 中的气流分配组件 18均采用多个气流分配板来实现，且每个分风道中的气流分 配板的数量、 结构、 分布位置及分别规律等均相同。 如图 3所示意， 该实施例 的气流分配组件 18共包括有四对、 八个气流分配板， 分别为主气流分配板 181 和 182、 第一辅助气流分配板 183和 184、 第二辅助气流分配板 185和 186、 第 三辅助气流分配板 187和 188。 所有气流分配板为具有相同弯曲方向的弯曲分 配板， 且每个气流分配板的表面均为弧形曲线面， 可以有效地引导风向， 并降 低气流在分流过程中的压损和噪音， 实现低噪音前提下的高速送风。 这四对气 流分配板以主气流分配板 181和 182在下、 第一辅助气流分配板 183和 184、 第二辅助气流分配板 185和 186及第三辅助气流分配板 187和 188依次往上的 顺序左右对称分布在环形热交换风分风道 1013的周向方向上。也即沿自下而上 的热交换风送风方向上，空调送风装置 10的左侧（以图 3的主视图而言的左右 方向） 自下而上设置有主气流分配板 181、第一辅助气流分配板 183、第二辅助 气流分配板 185和第三辅助气流分配板 187，而主气流分配板 182、第一辅助气 流分配板 184、 第二辅助气流分配板 186和第三辅助气流分配板 188以左右对 称的形式设置在空调送风装置 10的右侧。而且，各气流分配板的弯曲方向与热 交换风送风方向相逆。 热交换风送风方向自下而上， 则各气流分配板的弯曲反 向将是逆向送风方向， 即如图 3所示的逆时针方向弯曲。 Referring to the schematic diagram of the front view of FIG. 3, the air distribution assembly 18 in the annular heat exchange air separation duct 1013 of the embodiment is implemented by using a plurality of air distribution plates, and the air distribution plate in each of the air separation ducts The quantity, structure, distribution position and the law of separation are the same. As shown in FIG. 3, this embodiment The air distribution assembly 18 includes a total of four pairs and eight air distribution plates, which are main air distribution plates 181 and 182, first auxiliary air distribution plates 183 and 184, second auxiliary air distribution plates 185 and 186, and third auxiliary. Air distribution plates 187 and 188. All air distribution plates are curved distribution plates with the same bending direction, and the surface of each air distribution plate is curved curved surface, which can effectively guide the wind direction and reduce the pressure loss and noise of the airflow during the shunting process, achieving low High-speed air supply under the premise of noise. The four pairs of air distribution plates are sequentially in the order of the primary air distribution plates 181 and 182, the first auxiliary air distribution plates 183 and 184, the second auxiliary air distribution plates 185 and 186, and the third auxiliary air distribution plates 187 and 188. The left and right symmetrical distribution is in the circumferential direction of the annular heat exchange air dividing duct 1013. That is, in the direction of the heat exchange air supply from the bottom to the top, the left side of the air-conditioning air blower 10 (the left-right direction in the front view of FIG. 3) is provided with the main air distribution plate 181 from the bottom up. An auxiliary air distribution plate 183, a second auxiliary air distribution plate 185, and a third auxiliary air distribution plate 187, and the main air distribution plate 182, the first auxiliary air distribution plate 184, the second auxiliary air distribution plate 186, and the third auxiliary air flow The distribution plate 188 is disposed on the right side of the air-conditioning air blower 10 in a bilaterally symmetrical manner. Moreover, the bending direction of each air distribution plate is opposite to the heat exchange air blowing direction. When the heat exchange air supply direction is from bottom to top, the bending reverse direction of each air distribution plate will be the reverse air supply direction, that is, the counterclockwise direction as shown in FIG.
通过在热交换风风道中设置呈放射状对称分布的多个弯曲气流分配板构 成的气流分配组件 18， 可以利用主气流分配板 181和 182将来自蒸发器 16的 热交换风分成左、 中、 右三部分， 而左、 右两侧的热交换风又可以被各辅助气 流分配板再次分流，最终实现了空调送风装置 10的各热交换风分风道在周向方 向上进风及出风的均匀性， 提高了空调送风装置 10的送风均匀性。  The heat exchange wind from the evaporator 16 can be divided into left, center, and right by the main air distribution plates 181 and 182 by providing the air distribution assembly 18 formed by a plurality of curved air distribution plates arranged radially symmetrically in the heat exchange air duct. In the three parts, the heat exchange winds on the left and right sides can be diverted again by the auxiliary air distribution plates, and finally the air exchange air ducts of the air conditioning air supply device 10 are introduced into the wind and the air in the circumferential direction. The uniformity improves the uniformity of air supply of the air-conditioning air blower 10.
当然， 气流分配组件 18 除了采用多个弯曲气流分配板来实现之外， 还可 以采用其他的结构，只要能保证将来自蒸发器 16的热交换风在周向方向上进行 均匀分配即可。  Of course, the air distribution unit 18 can be implemented in addition to a plurality of curved air distribution plates, and other configurations can be employed as long as it is possible to uniformly distribute the heat exchange air from the evaporator 16 in the circumferential direction.
对于各个气流分配板， 其形状、 面积以及在热交换风分风道 1013 中的设 置位置是影响送风均匀性的关键性因素。 在该实施例中， 成对的气流分配板的 形状和面积均相同。 但是， 对于其中一侧的多个气流分配板来说， 自下而上， 主气流分配板 181或 182的面积大于第一辅助气流分配板 183或 184的面积， 第一辅助气流分配板 183或 184的面积大于第二辅助气流分配板 185或 186的 面积， 第四辅助气流分配板 185或 186的面积又大于第三辅助气流分配板 187 或 188的面积。 For each air distribution plate, its shape, area, and location in the heat exchange air separation duct 1013 are key factors influencing the uniformity of the air supply. In this embodiment, the shape and area of the pair of air distribution plates are the same. However, for a plurality of air distribution plates on one side, from bottom to top, The area of the primary air distribution plate 181 or 182 is larger than the area of the first auxiliary air distribution plate 183 or 184, and the area of the first auxiliary air distribution plate 183 or 184 is larger than the area of the second auxiliary air distribution plate 185 or 186, and the fourth auxiliary air flow. The area of the distribution plate 185 or 186 is again greater than the area of the third auxiliary air distribution plate 187 or 188.
而且， 由于周向方向上的气流密度不一致， 同一侧的各气流分配板按照不 等间距来分布。具体来说，主气流分配板 181或 182与第一辅助气流分配板 183 或 184之间的弧 L2的长度（表示了两者的间距）大于第一辅助气流分配板 183 或 184与第二辅助气流分配板 185或 186之间的弧 L3的长度，而第一辅助气流 分配板 183或 184与第二辅助气流分配板 185或 186之间的弧 L3的长度又大于 第二辅助气流分配板 185或 186与第三辅助气流分配板 187或 188之间的弧 L4 的长度。 优选的， 弧 L2、 弧 L3及弧 L4的长度之比为 6 : 5 : 3。  Moreover, since the airflow densities in the circumferential direction are not uniform, the air distribution plates on the same side are distributed at unequal intervals. Specifically, the length of the arc L2 between the primary air distribution plate 181 or 182 and the first auxiliary air distribution plate 183 or 184 (representing the distance between the two) is greater than the first auxiliary air distribution plate 183 or 184 and the second auxiliary The length of the arc L3 between the air distribution plates 185 or 186, and the length of the arc L3 between the first auxiliary air distribution plate 183 or 184 and the second auxiliary air distribution plate 185 or 186 is greater than the second auxiliary air distribution plate 185. Or the length of the arc L4 between the 186 and the third auxiliary air distribution plate 187 or 188. Preferably, the ratio of the lengths of the arc L2, the arc L3 and the arc L4 is 6:5:3.
此外，对于设置在环形热交换风分风道 1013中的主气流分配板 181和 182， 将其所在的两个环形热交换风分风道 1013划分为上、下两部分， 其中， 下部分 对应的弧为 Ll， 除 L1之外的弧均为上部分。 为保证周向方向上的送风均匀性， 下部分对应的弧 L1的弧长与上部分弧 （图中未标注， 是整个圆周方向上除 L1 之外的其余弧） 的弧长之比为 1 : 2-1 : 4。 而位于这两环形热交换风分风道 1013 顶部的第三辅助气流分配板 187和 188限定了顶部的一段弧 L5， 该段弧 L5的 长度占整个环形热交换风分风道 1013的周向总长度的 1/5-1/3。  In addition, for the main air distribution plates 181 and 182 disposed in the annular heat exchange air dividing duct 1013, the two annular heat exchange air dividing ducts 1013 in which they are located are divided into upper and lower portions, wherein the lower portion corresponds to The arc is L1, and the arcs other than L1 are the upper part. In order to ensure the uniformity of the air supply in the circumferential direction, the arc length of the corresponding arc L1 of the lower part and the arc length of the upper part arc (not shown in the figure, which is the remaining arc except L1 in the entire circumferential direction) are 1 : 2-1 : 4. The third auxiliary air distribution plates 187 and 188 at the top of the two annular heat exchange air separation ducts 1013 define a section of the arc L5 at the top, the length of the section of the arc L5 occupies the circumference of the entire annular heat exchange air duct 1013. 1/5-1/3 of the total length.
在该实施例中， 前面板 11上的混合风出口 111和后背板 12上的非热交换 风进口 121 的优选形状为圆形， 相应的， 空调送风装置 10 中的环形罩体 101 的形状优选为圆环形。 此外， 还可以设计成其他形状的组合， 如椭圆形和椭圆 环、 正多边形和正多边形环等， 也都能实现本发明的技术目的。  In this embodiment, the preferred shape of the mixed air outlet 111 on the front panel 11 and the non-heat exchanged air inlet 121 on the back panel 12 is circular, and correspondingly, the annular enclosure 101 in the air-conditioning air supply device 10 The shape is preferably a circular ring shape. Further, it is also possible to design a combination of other shapes such as an elliptical and elliptical ring, a regular polygon, and a regular polygon ring, and the like, and the technical object of the present invention can also be achieved.
