Description

壁挂式空调室内机Wall-mounted air conditioner indoor unit 技术领域technical field
本发明涉及空气调节技术领域，特别涉及一种壁挂式空调室内机。The invention relates to the technical field of air conditioning, in particular to a wall-mounted air conditioner indoor unit.
背景技术Background technique
由于冷空气密度相对较大有下沉趋势，热空气密度相对较小有上升趋势。因此，空调在制冷时需要将较冷风尽量向上吹，在制热时需要将热风尽量朝地面吹，以使冷风或热风在室内空间扩散更加均匀，使制冷制热速度更快。Because the density of cold air is relatively high, it tends to sink, while the density of hot air is relatively low, and it tends to rise. Therefore, the air conditioner needs to blow the colder air upward as much as possible when cooling, and blow the hot air toward the ground as much as possible when heating, so that the cold or hot air can spread more evenly in the indoor space and make the cooling and heating speed faster.
现有的壁挂式空调室内机通常设置一个朝前的出风口，并利导风板、摆叶等导风结构引导送风气流的出风方向，实现上吹风或下吹风。但是，当前的各种导风结构导风角度比较有限，也仅能向斜上方或斜下方送风，冷风或热风难以抵达屋顶或地面，影响制冷或制热效果。Existing wall-mounted air-conditioning indoor units are usually provided with a front-facing air outlet, and the wind-guiding structures such as wind deflectors and swing leaves are used to guide the air outlet direction of the air-supply airflow, so as to realize upward blowing or downward blowing. However, the various current air guide structures have relatively limited air guide angles, and can only supply air obliquely upward or downward. It is difficult for cold or hot air to reach the roof or the ground, which affects the cooling or heating effect.

本发明的壁挂式空调室内机中，机壳外设置有一个导风罩板，导风罩板与机壳外周面限定出导风通道。机壳内部的送风气流(例如冷风、热风、新风或净化气流等)从机壳的出风口吹出后，在导风罩板的引导下，沿着机壳的外周面向上和/或向下吹出。由于送风气流紧贴着机壳外周面流动，形成附壁效应，能够沿机壳外周面顺利到达屋顶或地面，使壁挂式空调室内机的制冷或制热效果更好，同时也能避免冷风或热风吹人导致人体不舒适。In the wall-mounted air conditioner indoor unit of the present invention, an air guiding cover plate is arranged outside the casing, and the air guiding cover plate and the outer peripheral surface of the casing define an air guiding channel. After the air supply airflow (such as cold air, hot air, fresh air or purified airflow, etc.) inside the casing is blown out from the air outlet of the casing, it is guided upward and/or downward along the outer peripheral surface of the casing under the guidance of the wind deflector plate. blow out. Because the air supply airflow flows close to the outer peripheral surface of the casing, forming a wall attachment effect, it can smoothly reach the roof or the ground along the outer peripheral surface of the casing, so that the cooling or heating effect of the wall-mounted air conditioner indoor unit is better, and it can also avoid cold wind. Or the hot wind blows people and causes discomfort to the human body.
本发明并非使全部送风气流都沿机壳向上或向下流动，而是使一部分送 风气流经导风罩板的透风部位向外吹出，这使得空调送风方向更加多元化，使得该部分送风气流形成微风气流，人体感觉更加舒适。The present invention does not make all the air supply flow upward or downward along the casing, but makes a part of the air supply flow blow out through the ventilation part of the wind guide cover plate, which makes the air supply direction of the air conditioner more diversified and makes this part The air supply airflow forms a breeze airflow, and the human body feels more comfortable.

For example, when the air conditioner needs to operate in the down blowing mode for heating, move the air baffle plate to the position where the lower passage is opposite to the air outlet, and the lower passage guides the air supply airflow downward. When the air conditioner needs to operate in the upward blowing mode, move the air guide cover to the position where the upper channel is opposite to the air outlet, and the upper channel will guide the air supply upward, and a part of the cold air will be blown out through the ventilation part to form a cool breeze. Make the human body feel more comfortable.
进一步地，本发明的壁挂式空调室内机中，使分隔部的上下表面均为内凹的弧面，使送风气流在从出风口吹出然后向上或向下转向时，方向变化地更加缓和，减少风力损失和噪声。Further, in the wall-mounted air conditioner indoor unit of the present invention, the upper and lower surfaces of the partition are concave arc surfaces, so that when the air flow is blown out from the air outlet and then turned upward or downward, the direction change is more moderate, Reduce wind loss and noise.
进一步地，本发明的壁挂式空调室内机，使机壳前表面为竖直面，以更利于送风气流在机壳前表面形成附壁效应，从而更好地沿机壳前表面向上或向下流动。此外，使出风口下边缘距机壳前表面底端的间距与出风口的宽度之比大于1/2，使出风口下方的机壳前表面具有足够的高度，以便在空调运行下吹模式时，以使下通道更长，以更利于形成附壁效应，将送风气流更好地向正下方引导。Further, in the wall-mounted air conditioner indoor unit of the present invention, the front surface of the casing is made to be a vertical surface, which is more conducive to the formation of a Coanda effect on the front surface of the casing by the air supply airflow, so as to better move upward or downward along the front surface of the casing. flow down. In addition, the ratio of the distance between the lower edge of the air outlet and the bottom end of the front surface of the casing to the width of the air outlet is greater than 1/2, so that the front surface of the casing below the air outlet has a sufficient height so that when the air conditioner is running in the down blowing mode, The lower channel is made longer, which is more conducive to the formation of the Coanda effect, and better guides the supply air flow directly downward.

如图1至图8所示，本发明实施例的壁挂式空调室内机一般性地可包括机壳10和导风罩板20。As shown in FIGS. 1 to 8 , the wall-mounted air conditioner indoor unit according to the embodiment of the present invention may generally include a casing 10 and a wind deflector plate 20 .
机壳10上开设有出风口12，用于将机壳10内的送风气流排向室内。该送风气流可为壁挂式空调室内机在制冷模式下制取的冷风，在制热模式下制取的热风，或者在新风模式下引入的新风，或者为净化模式下产生的净化气流等等。机壳10在整体上可为横向延伸的长条状结构。The casing 10 is provided with an air outlet 12 for discharging the air supply air in the casing 10 to the room. The supply air flow can be the cold air produced by the indoor unit of the wall-mounted air conditioner in the cooling mode, the hot air produced in the heating mode, or the fresh air introduced in the fresh air mode, or the purified air generated in the purification mode, etc. . The casing 10 as a whole can be a strip-like structure extending laterally.
导风罩板20设置在出风口12的外侧，以与机壳10的外周面限定出导风通道21。即，导风罩板20与机壳10的外周面平行或接***行，两者之间间隔的空间构成导风通道21。导风通道21用于引导从出风口12流出的送风气流沿机壳10的外周面向上和/或向下流动。即，送风气流(例如冷风、热风、新风或净化气流等)从机壳10的出风口12吹出后，在导风罩板20的内壁的引导下，沿着机壳10的外周面向上和/或向下吹出。该处的向上和/或向下吹出指的是：可以使送风气流仅能向上吹出，或者仅能向下吹出，或者既能向上又能向下吹出。图1至图5即示意了送风气流向上吹出的情况，图6至图8即示意了送风气流向下吹出的情况，图13示意了送风气流能同时向上、向下吹出的方案。The wind guide hood 20 is disposed outside the air outlet 12 to define an air guide channel 21 with the outer peripheral surface of the casing 10 . That is, the air guide hood 20 is parallel or nearly parallel to the outer peripheral surface of the casing 10 , and the space between them constitutes the air guide channel 21 . The air guide channel 21 is used to guide the air flow flowing out from the air outlet 12 to flow upward and/or downward along the outer peripheral surface of the casing 10 .

Figures 1 to 5 illustrate the situation in which the air supply air is blown upward, Figures 6 to 8 illustrate the situation in which the air supply air is blown downward, and Figure 13 illustrates the scheme in which the air supply air can be blown upward and downward at the same time.
由于送风气流紧贴着机壳10的外周面向上或向下流动，能够形成附壁效应(也可称为贴附效应)，从而能够沿机壳10的外周面顺利到达屋顶或者地面，使壁挂式空调室内机的制冷或制热效果更好。同时也能避免冷风或热风吹人导致人体不适。Because the air supply air flows upwards or downwards close to the outer peripheral surface of the casing 10, a Coanda effect (also called the sticking effect) can be formed, so that it can smoothly reach the roof or the ground along the outer peripheral surface of the casing 10, so that The cooling or heating effect of the wall-mounted air conditioner indoor unit is better. At the same time, it can also avoid cold or hot wind blowing people and causing discomfort to the human body.
导风罩板20具有透风部位209，换言之透风部位209为导风罩板20的一部分。导风通道21内的部分送风气流穿透透风部位209吹向导风罩板20的外侧。之所以设置透风部为209，是要避免全部送风气流沿机壳10向上或向下流动，使一部分送风气流经透风部位209向外吹出，使空调送风方向更 加多元化，送风气流扩散更快，室内温度变化更加均匀，人体感觉更加舒适。可通过推透风部位209的透风口径进行设计，使其透过的气流流速更低，形成微风效果，提升人体舒适感。The wind deflector plate 20 has a ventilation portion 209 , in other words the ventilation portion 209 is a part of the wind deflector plate 20 . Part of the air supply airflow in the air guide channel 21 passes through the air-permeable portion 209 and blows to the outside of the air guide cover plate 20 . The reason why the ventilation part is set as 209 is to prevent all the air supply air from flowing upward or downward along the casing 10, so that a part of the air supply air is blown out through the ventilation part 209, so that the air supply direction of the air conditioner is more diversified, and the air supply air flow The diffusion is faster, the indoor temperature changes more evenly, and the human body feels more comfortable. The ventilation aperture of the ventilation part 209 can be pushed to design, so that the flow rate of the airflow passing through it is lower, forming a breeze effect and improving the comfort of the human body.
参考图1至图5，透风部位209可为格栅状，送风气流经格栅的各镂空孔向外吹出。可将格栅楼空孔设计地更加致密，以使其微风效果更好。另外，也可使透风部位209为孔板状，即在导风罩板20上开设有多个散风微孔，以向外排出微风气流。Referring to FIG. 1 to FIG. 5 , the ventilating part 209 may be in the shape of a grille, and the blown air is blown out through each hollow hole of the grille. The grid floor holes can be designed to be denser to make its breeze effect better. In addition, the ventilating part 209 can also be made in the shape of a perforated plate, that is, a plurality of air-dispersing micro-holes are opened on the air guide cover plate 20 to discharge the breeze air to the outside.
在一些实施例中，可使机壳10外周面中，有送风气流流经的区域为平坦表面，以利于送风气流更好地贴合着机壳10的外周面流动。例如图1所示，对于出风口12开设于机壳10的前侧的方案，机壳10的前表面即新风气流流经的外周面，可使机壳10的前表面为平坦表面。In some embodiments, the area on the outer peripheral surface of the casing 10 where the blown airflow flows may be a flat surface, so as to facilitate the blown airflow to flow along the outer peripheral surface of the casing 10 better. For example, as shown in FIG. 1 , for the solution in which the air outlet 12 is set on the front side of the casing 10 , the front surface of the casing 10 , that is, the outer peripheral surface through which the fresh air flows, can make the front surface of the casing 10 a flat surface.
在一些实施例中，如图1和图8所示，可使导风罩板20可上下平移地安装于机壳10。此时，导风罩板20为竖置的板状。并且，导风罩板20具有从其内侧表面朝所述机壳10的外周面凸出的分隔部23。分隔部23用于将导风通道21分隔为开口朝上的上通道212和开口朝下的下通道214。导风罩板20配置成：可移动至使下通道214与出风口12相对的位置，以由下通道214将送风气流向下引导，如图6至图8；或移动至使上通道212与出风口12相对的位置，以由上通道212将送风气流向上引导，如图1至图4。In some embodiments, as shown in FIG. 1 and FIG. 8 , the wind deflector plate 20 can be installed on the casing 10 so that it can move up and down. At this time, the wind deflector plate 20 is in the shape of a vertical plate. Furthermore, the wind deflector 20 has a partition 23 protruding from the inner surface thereof toward the outer peripheral surface of the casing 10 . The partition 23 is used to divide the air guide channel 21 into an upper channel 212 with an opening facing upward and a lower channel 214 with an opening facing downward. The wind deflector plate 20 is configured to: move to a position where the lower channel 214 is opposite to the air outlet 12, so that the lower channel 214 guides the air flow downward, as shown in Figures 6 to 8; or move to make the upper channel 212 and the air outlet 12 The position of the air outlet 12 is opposite, so that the upper channel 212 guides the air flow upward, as shown in FIGS. 1 to 4 .
如此一来，使壁挂式空调室内机具有上吹模式和下吹模式以供选择，使制冷和制热效果得到显著提升。例如，当空调制热需要运行下吹模式时，移动导风罩板20，由下通道214将送风气流向下引导，如图8。当空调制冷需要运行上吹模式时，移动导风罩板20，由上通道212将送风气流向上引导，如图4。当然，还可使导风罩板20配置成可移动至使分隔部23位于出风口12的竖直方向的中部位置(未图示，即处于位于图4与图8之间的位置)，以由下通道214和上通道212各自引导部分送风气流，以使壁挂式空调室内机同时向上下两个方向送风，提升空气调节速度。In this way, the wall-mounted air conditioner indoor unit has an up-blowing mode and a down-blowing mode for selection, so that the cooling and heating effects are significantly improved. For example, when the air conditioner needs to operate in the down blowing mode for heating and heating, the air guide hood 20 is moved, and the air supply airflow is guided downward by the lower channel 214 , as shown in FIG. 8 . When the air conditioner needs to operate in the upward blowing mode, the air guide plate 20 is moved, and the upper channel 212 guides the air flow upward, as shown in FIG. 4 . Of course, the wind deflector plate 20 can also be configured to be movable to make the partition 23 located in the middle of the vertical direction of the air outlet 12 (not shown, that is, in a position between FIG. 4 and FIG. 8 ), so as to The lower channel 214 and the upper channel 212 respectively guide part of the air flow, so that the indoor unit of the wall-mounted air conditioner supplies air in both directions up and down at the same time, increasing the air conditioning speed.
可使透风部位209位于分隔部23的上方，以允许上通道212内的送风气流通过透风部位209吹向导风罩板20的外侧，参考图5。也就是说，在空调制冷时，冷风对人体刺激更大，特利用透风部位209向外散风，使冷风扩散更快，且形成微风冷气流，使人体更加舒适。在空调制热时，由于用户更在乎热风下吹的效果，透风部位209不发挥作用，使热风全力下吹，以尽快 达到暖脚效果。The ventilation part 209 can be located above the partition part 23 to allow the air flow in the upper channel 212 to blow to the outside of the wind guide hood 20 through the ventilation part 209 , referring to FIG. 5 . That is to say, when the air conditioner is refrigerating, the cold wind is more irritating to the human body, and the ventilation part 209 is specially used to disperse the wind outward, so that the cold wind can spread faster and form a breeze and cold air flow to make the human body more comfortable. When the air conditioner is heating, because the user cares more about the effect of the hot air blowing down, the ventilation part 209 does not play a role, so that the hot air is fully blown down, so as to reach the effect of warming the feet as soon as possible.
在一些实施例中，如图1至图8所示，可使透风部位209邻近导风罩板20的顶边。使透风部位209为沿着导风罩板20的顶边延伸的条带状。这样一来，避免因设置透风部位209使得冷风过多经透风部位流出，以致损害了冷风上吹的效果。In some embodiments, as shown in FIGS. 1 to 8 , the ventilation portion 209 may be adjacent to the top edge of the wind deflector panel 20 . The ventilation part 209 is made into a strip shape extending along the top edge of the wind deflector hood 20 . In this way, it is avoided that due to the arrangement of the ventilation part 209, the cold air flows out through the ventilation part too much, so that the effect of blowing the cold wind upward is damaged.
在一些实施例中，如图4和图5所示，分隔部23具有一邻近机壳10的外周面的尖端230。尖端230邻近机壳10的外周面，可使其与机壳10的外周面贴合。在导风罩板20处于上吹位置时，使分隔部23与机壳10外周面之间密封性能更好，避免气流向下泄漏；在导风罩板20处于下吹位置时，使分隔部23与机壳10外周面之间密封性能更好，避免气流向上泄漏。当然，假如尖端230与机壳10的外表面相贴过紧，当导风罩板20上下移动时，尖端230与机壳10的外表面相互摩擦可能会产生较大噪声。为避免该噪声，也可使尖端230与机壳10的外表面保留一定的缝隙。In some embodiments, as shown in FIGS. 4 and 5 , the partition 23 has a tip 230 adjacent to the outer peripheral surface of the housing 10 . The tip 230 is adjacent to the outer peripheral surface of the casing 10 so as to be attached to the outer peripheral surface of the casing 10 . When the wind deflector plate 20 is in the upward blowing position, the sealing performance between the partition 23 and the outer peripheral surface of the casing 10 is better to prevent the airflow from leaking downward; when the wind deflector plate 20 is in the downward blowing position, the partition is made The sealing performance between 23 and the outer peripheral surface of the casing 10 is better, so as to avoid upward leakage of the airflow. Of course, if the tip 230 is too tightly attached to the outer surface of the casing 10 , when the wind deflector plate 20 moves up and down, the tip 230 and the outer surface of the casing 10 may rub against each other to generate loud noise. In order to avoid this noise, a certain gap can also be reserved between the tip 230 and the outer surface of the casing 10 .
请参考图4和图5，分隔部23的上表面231为从尖端230起始，朝远离机壳10的方向(图中所示具体实施例中，指的是朝前)延伸并逐渐向上倾斜，并与导风罩板20其余部分内侧表面相切的内凹的弧面。同样地，分隔部23的下表面232为从尖端230起始，朝远离机壳10的方向延伸并逐渐向下倾斜，并与导风罩板20的其余部分内侧表面相切的内凹的弧面。如此一来，在送风气流在从出风口12吹出然后向上或向下转向时，将沿着分隔部23的上表面或下表面逐渐转向，过程更加缓和，风力损失和噪声更小。Please refer to FIG. 4 and FIG. 5, the upper surface 231 of the partition 23 starts from the tip 230, extends away from the casing 10 (in the specific embodiment shown in the figure, refers to the front) and gradually slopes upward. , and a concave arc surface tangent to the inner surface of the rest of the wind deflector plate 20 . Similarly, the lower surface 232 of the partition 23 is a concave arc that starts from the tip 230 , extends away from the casing 10 and gradually slopes downward, and is tangent to the inner surface of the rest of the wind deflector 20 . noodle. In this way, when the air flow blows out from the air outlet 12 and then turns upward or downward, it will gradually turn along the upper or lower surface of the partition 23 , the process is more gentle, and the wind loss and noise are smaller.
当导风罩板20处于上吹模式时，可使分隔部23的尖端230与出风口12的下边缘位置相对，以使分隔部23的上表面231与风道40的下壁相接，参考图4。并且，由于分隔部23的上表面231为内凹的弧面，这使得上表面231相当于风道40的下壁的延长段，使得从风道40流出的送风气流很顺畅、低阻力地进入分隔部23的引导范围。When the wind deflector 20 is in the upward blowing mode, the tip 230 of the partition 23 can be made to be opposite to the lower edge of the air outlet 12, so that the upper surface 231 of the partition 23 is in contact with the lower wall of the air duct 40. Figure 4. Moreover, since the upper surface 231 of the partition 23 is a concave arc surface, this makes the upper surface 231 equivalent to the extension of the lower wall of the air duct 40, so that the air flow flowing out of the air duct 40 is smooth and low-resistance. Enter the guide range of the partition 23 .
同样道理，当导风罩板20处于下吹模式时，可使分隔部23的尖端230与出风口12的上边缘位置相对，以使分隔部23的下表面232与风道40的上壁相接，参考图8。由于分隔部23的下表面232为内凹的弧面，这使得下表面232相当于风道40的上壁的延长段，使得从风道40流出的送风气流很顺畅、低阻力地进入分隔部23的引导范围。In the same way, when the wind deflector 20 is in the down blowing mode, the tip 230 of the partition 23 can be made to be opposite to the upper edge of the air outlet 12, so that the lower surface 232 of the partition 23 is in contact with the upper wall of the air duct 40. Then, refer to Figure 8. Since the lower surface 232 of the partition 23 is a concave arc surface, the lower surface 232 is equivalent to the extension of the upper wall of the air duct 40, so that the air flow flowing out from the air duct 40 enters the partition smoothly and with low resistance. Part 23 of the boot range.
在一些实施例中，如图1至图8所示，可使机壳10的前表面整体为竖 直面(机壳10的前表面即机壳10的外周面的一部分)，具体地可为竖直的平面或者为轴线沿竖直延伸的弧面等曲面。出风口12可开设于机壳10的前表面的下部。出风口12更具体地可为长度方向平行于机壳10的横向方向的长条状。In some embodiments, as shown in FIGS. 1 to 8 , the front surface of the casing 10 may be a vertical surface as a whole (the front surface of the casing 10 is a part of the outer peripheral surface of the casing 10 ), specifically, A vertical plane or a curved surface such as an arc whose axis extends vertically. The air outlet 12 can be opened at the lower portion of the front surface of the casing 10 . More specifically, the air outlet 12 may be in the shape of a strip whose length direction is parallel to the transverse direction of the casing 10 .
请参考图5，出风口12的下边缘d距机壳10前表面底端e的间距(de)与出风口12的宽度(cd)之比大于1/2，即de/cd＞1/2，优选大于3/4。如此，当壁挂式空调室内机运行下吹模式时，使出风口12下边缘以下的机壳10前表面具有足够的长度来引导送风气流向下流动，提升附壁效应。此外，还可使分隔部23距导风罩板20底端的距离大于分隔部23距导风罩板20顶端的距离(具体可以分隔部23的尖端230为测量基准)，也就是使分隔部23处于导风罩板20的上部，以便在下吹模式时更好地引导气流下吹，弥补出风口12下侧的机壳前表面引导距离(即de)较短的缺陷。Please refer to Figure 5, the ratio of the distance (de) between the lower edge d of the air outlet 12 and the bottom e of the front surface of the casing 10 and the width (cd) of the air outlet 12 is greater than 1/2, that is, de/cd>1/2 , preferably greater than 3/4. In this way, when the wall-mounted air conditioner indoor unit operates in the down blowing mode, the front surface of the casing 10 below the lower edge of the air outlet 12 has sufficient length to guide the air supply airflow to flow downward, thereby improving the Coanda effect. In addition, the distance between the partition 23 and the bottom end of the wind deflector 20 can also be greater than the distance between the partition 23 and the top of the wind deflector 20 (specifically, the tip 230 of the partition 23 can be used as a measurement reference), that is, the partition 23 It is located on the upper part of the air guide hood 20 so as to better guide the airflow to blow down in the down blowing mode, so as to make up for the short guide distance (ie de) of the front surface of the casing on the lower side of the air outlet 12 .
请参考图1至图3，对于出风口12开设于机壳10的前表面的方案，可使导风罩板20包括前部区段201和两个弯折区段202。其中，前部区段201位于出风口12的前方，主要用于引导送风气流。两个弯折区段202分别从前部区段201的横向两端向后延伸出，以分别安装于机壳10的横向两侧的端盖106。本实施例中，导风罩板20通过两个弯折区段202与机壳10横向的端盖106连接，使导风罩板20的前侧外观更加完整，也无需在机壳10的前侧设置驱动机构导致占据出风空间。并且，使每个弯折区段202具有朝端盖106延伸的挡风部2021，以用于阻挡送风气流向后流动，使送风气流更好地向上或向下流动，避免向后流动扩散影响向上、向下的风力。Please refer to FIG. 1 to FIG. 3 , for the solution in which the air outlet 12 is disposed on the front surface of the casing 10 , the wind deflector panel 20 may include a front section 201 and two bent sections 202 . Wherein, the front section 201 is located in front of the air outlet 12 and is mainly used to guide the airflow. The two bent sections 202 respectively extend backward from two transverse ends of the front section 201 to be respectively mounted on the end covers 106 on both transverse sides of the casing 10 . In this embodiment, the wind deflector plate 20 is connected to the lateral end cover 106 of the casing 10 through two bending sections 202, so that the appearance of the front side of the wind deflector plate 20 is more complete, and there is no need for a front side of the casing 10. The side setting of the drive mechanism leads to occupation of the air outlet space. Moreover, each bent section 202 has a windshield portion 2021 extending toward the end cover 106 to block the rearward flow of the air supply airflow, so that the air supply airflow can flow upwards or downwards better, and avoid backward flow diffusion Affects upward and downward wind.

如图9至图12所示，机壳10的至少一个端盖上设置有齿轮齿条机构，用于驱动导风罩板20上下平移，实现上吹位置和下吹位置之间的切换。优选地，使两个端盖106上均设置有齿轮齿条机构，以带动导风罩板20的横向两端同步上移或下移，使其移动更加平稳、顺畅。As shown in FIG. 9 to FIG. 12 , at least one end cover of the casing 10 is provided with a rack and pinion mechanism, which is used to drive the wind deflector plate 20 to translate up and down, so as to realize switching between the blowing up position and the blowing down position. Preferably, rack and pinion mechanisms are provided on the two end covers 106 to drive the lateral ends of the wind deflector 20 to move up or down synchronously to make the movement more stable and smooth.
每个齿轮齿条机构包括电机71、相互啮合的齿轮72和齿条73。电机71设置于端盖106的内侧。齿轮72安装于电机71，齿条73可上下平移地设置于端盖106的内侧，且其一部分通过端盖106上开设的竖直长条让位孔1061 伸出至端盖106的外侧，以便与导风罩板20连接。电机71带动齿轮72转动时，齿轮72带动齿条73上下平移，以驱动导风罩板20上下平移。Each rack and pinion mechanism includes a motor 71 , a gear 72 and a rack 73 that mesh with each other. The motor 71 is disposed inside the end cover 106 . The gear 72 is installed on the motor 71, the rack 73 can be arranged on the inner side of the end cover 106 in translation up and down, and a part of it protrudes to the outside of the end cover 106 through the vertical elongated hole 1061 provided on the end cover 106, so that It is connected with the wind deflector plate 20. When the motor 71 drives the gear 72 to rotate, the gear 72 drives the rack 73 to translate up and down to drive the wind deflector plate 20 to translate up and down.
具体地，如图11至图12所示，可使端盖106的内壁固定有一安装件107。安装件107通过其上设置的多个安装部1072与端盖106内壁设置的多个安装部1062通过螺钉连接。安装件107形成有两个间隔设置且竖向延伸的滑轨1071。齿条73的宽度方向的两端形成有开口方向相反的两个滑槽731，每个滑槽731与一个滑轨1071匹配，以允许齿条73沿安装件107上下滑动。即，安装件107的作用是形成滑轨1071以供使齿条73可上下平移地安装其上。Specifically, as shown in FIGS. 11 to 12 , a mounting piece 107 can be fixed on the inner wall of the end cover 106 . The mounting part 107 is connected with the multiple mounting parts 1062 provided on the inner wall of the end cover 106 by screws through the multiple mounting parts 1072 provided thereon. The mounting member 107 is formed with two sliding rails 1071 arranged at intervals and extending vertically. Two sliding slots 731 with opposite opening directions are formed at both ends of the rack 73 in the width direction, and each sliding slot 731 is matched with a sliding rail 1071 to allow the rack 73 to slide up and down along the mounting member 107 . That is, the function of the mounting part 107 is to form a slide rail 1071 for the rack 73 to be mounted on it in a translational up and down manner.
端盖106的内壁还固定有一支架108，以安装电机71。齿条73被夹在齿轮72与安装件107之间，或者说是齿轮72位于安装件107背向端盖106的内壁的一侧。齿条73朝向齿轮72的一侧形成有齿以与齿轮72啮合，朝向端盖106的一侧向外凸出形成一凸条732，凸条732通过竖直长条让位孔1061伸出端盖106并与导风罩板20连接，例如通过螺钉连接。具体地，可使凸条732连接于挡风部2021上。如此，使得挡风部2021既用于连接凸条732，又能阻挡气流，设计非常巧妙。A bracket 108 is also fixed on the inner wall of the end cover 106 to install the motor 71 . The rack 73 is sandwiched between the gear 72 and the mounting part 107 , or the gear 72 is located on the side of the mounting part 107 facing away from the inner wall of the end cover 106 . The side of the rack 73 facing the gear 72 is formed with teeth to mesh with the gear 72, and the side facing the end cover 106 protrudes outward to form a raised bar 732, and the raised bar 732 extends out through the vertical elongated hole 1061 The cover 106 is also connected to the wind deflector plate 20 , for example, by screws. Specifically, the protruding strip 732 can be connected to the windshield part 2021 . In this way, the windshield part 2021 is not only used for connecting the convex strip 732, but also can block the airflow, and the design is very clever.
本实施例通过在端盖106的内壁设置安装件107和支架108，将齿轮齿条机构的主体结构安装于端盖106的内侧，不影响壁挂式空调室内机的外观。并通过在端盖106上开设竖直长条让位孔1061以连接位于端盖106外侧的导风罩板20，设计非常简单、合理。In this embodiment, the mounting part 107 and the bracket 108 are provided on the inner wall of the end cover 106, and the main structure of the rack and pinion mechanism is installed on the inner side of the end cover 106, without affecting the appearance of the wall-mounted air conditioner indoor unit. And by setting up the vertical strip relief hole 1061 on the end cover 106 to connect the wind deflector plate 20 located outside the end cover 106, the design is very simple and reasonable.

A cross-flow fan 50 whose axis extends in the transverse direction is disposed at the inlet of the air duct 40 . The three-stage heat exchanger 30 surrounds the cross-flow fan 50 . When the indoor unit of the wall-mounted air conditioner is in the cooling mode or heating mode, the indoor air enters the interior of the casing 10 through the air inlet 11, completes heat exchange with the three-stage heat exchanger 30, and is finally sucked into the air duct 40 by the cross-flow fan 50 , flow to the air outlet 12.
