- the indoor unit 100 of the present application can be installed indoors, and the outdoor unit is responsible for cooling or heating, and transports refrigerant or chilled water and other media through connecting pipes. After the refrigerant or chilled water and other media exchange heat with the indoor air and outdoor air respectively, the indoor unit 100 is responsible for transporting cold air or hot air into the room to achieve the effect of cooling or heating.
- the indoor unit 100 includes a housing 10 , a heat exchanger 40 , and a crossflow impeller 20 .
- the heat exchanger 40 and the crossflow impeller 20 are both disposed in an air duct of the housing 10 .
- the outer contour of the housing 10 can be set in a rectangular block shape, and the material of the housing 10 can be metal, which has advantages such as good strength, lightness, and corrosion resistance. Of course, the material of the housing 10 can also be plastic, which has advantages such as light weight, low cost, and easy processing and molding. This embodiment does not limit the shape and material of the housing 10.
- the bottom surface can be located on the ceiling and facing the indoor environment.
- the bottom surface of the housing 10 is provided with an air inlet 10a and an air outlet 10b at intervals, and an air duct connecting the air inlet 10a and the air outlet 10b is formed inside the housing 10.
- the housing 10 further includes a volute tongue 11, which is located between the crossflow impeller 20 and the air outlet 10b. The volute tongue 11 is used to divide the airflow sent to the air outlet 10b by the crossflow impeller 20 so that part of the airflow can flow smoothly to the air outlet 10b.
- the heat exchanger 40 can have a variety of shapes, such as straight, V-shaped, curved, or wavy.
- the heat exchanger 40 is used to exchange heat with the gas passing through the heat exchanger 40, thereby cooling or heating the gas.
- a plurality of refrigerant pipes are provided in the heat exchanger 40.
- the gas passes through the heat exchanger 40, it exchanges heat with the refrigerant in the pipes, thereby changing the temperature of the gas.
- the gas exchanges heat with the refrigerant in the heat exchanger 40 to form low-temperature air
- the gas exchanges heat with the refrigerant in the heat exchanger 40 to form heated air.
- the heat exchanger 40 is disposed in the air duct and is located between the crossflow impeller 20 and the air inlet 10a. In this way, the airflow entering the air inlet 10a will first exchange heat with the heat exchanger 40, and then pass through the crossflow impeller 20 and be blown into the indoor scene from the air outlet 10b. In this way, the heat exchanger 40 is disposed away from the air outlet 10b to reduce the interference of the heat exchanger 40 with the air outlet direction.
- the housing 10 includes a casing 12, a panel 13, and a water tray 14.
- the casing 12 can be made of alloys or metals such as aluminum and steel. These materials meet the structural strength requirements and ensure a long service life for the indoor unit 100. Of course, the casing 12 can also be made of plastic to achieve the advantage of being lighter in weight. This application does not impose any specific restrictions on the material of the casing 12.
- the casing 12 not only protects the internal components but also allows for compatible connection with the indoor environment.
- the bottom of the casing 12 is open, with the panel 13 covering the open area.
- the air inlet 10a and air outlet 10b are spaced apart on the panel 13.
- the panel 13 is detachably connected to the bottom of the casing 12.
- a water receiving pan 14 is provided below the bottom of the heat exchanger 40 to receive the condensed water, so as to prevent the condensed water from damaging the heat exchanger 40 and other components of the indoor unit 100 and ensure the normal operation of the indoor unit 100.
- the crossflow impeller 20 has the advantages of energy saving, large air volume, low operating noise, and simple installation. Therefore, the crossflow impeller 20 is used to drive the airflow to improve the performance of the indoor unit 100.
- the crossflow impeller 20 can be arranged in a long cylindrical shape, and the crossflow impeller 20 includes blades 222.
- the cross-sectional shape of the blades 222 can be an airfoil shape, which can optimize the distribution of the airflow on the surface of the blades 222, making the airflow flowing through the surface of the blades 222 more uniform and reducing the turbulence of the airflow on the surface of the blades 222, thereby improving the overall aerodynamic performance of the crossflow impeller 20.
- the inclined blades 222 can change the direction and speed of the air flow, and then can achieve flexible adjustment of the air supply distance and air supply width according to the actual indoor scene by adjusting the inclination angle of the blades 222 and the coordinated operation of multiple cross-flow impellers 20, thereby broadening the use scenarios of the indoor unit 100 and meeting the diverse air supply needs in the actual environment. It has positive significance in optimizing the indoor air environment, improving human comfort, and helping the indoor unit 100 save energy.
- the concentrated airflow can also increase the air circulation speed in specific areas of the room to a certain extent, optimize the indoor air environment, and enhance human comfort.
- this structure is simpler during the manufacturing and assembly process, reducing production difficulty and cost.
- the air outlet tail end 2221 includes a plurality of spaced-apart air outlet portions 222a, with an air supply cutout 222b defined between two adjacent air outlet portions 222a.
- the air supply cutout 222b is configured to transition the airflow at the air supply cutout 222b from a laminar flow state to a turbulent flow state.
- the large vortex in the wake of the airflow can be transformed into multiple small vortices in advance. This not only reduces the intensity of the noise generated by the airflow as it flows toward the volute tongue 11, but also reduces the intensity of the noise generated when multiple small vortices impact the volute tongue 11 compared to when a large vortex impacts the volute tongue 11.
- this differentiated airflow output creates a more complex and diverse airflow combination at the air outlet 10b.
- it expands the airflow coverage, allowing a wider area of the indoor space to be covered by the airflow, avoiding dead spots and optimizing indoor air uniformity.
- the interweaving of airflows at different speeds and angles helps enhance the airflow's diffusion capacity within the room, improving air circulation efficiency and thus enhancing the indoor unit's air conditioning capabilities, creating a more comfortable indoor air environment for the user.
- this differentiated airflow output pattern creates a unique airflow pattern at the air outlet 10b.
- this design tends to concentrate airflow toward a specific area, significantly increasing the air delivery distance.
- This allows the indoor unit 100 to deliver airflow to locations farther away, effectively achieving long-range air delivery and conditioning in larger spaces such as shopping malls and large conference rooms.
- the airflow intensity in a specific direction is enhanced, which is crucial for targeted improvements in localized air quality. For example, in areas with high requirements for local environmental parameters such as temperature and humidity, these requirements can be more precisely met.
- the projection distance changes of the multiple air outlets 222a in each blade 222 in each group to the rotation center axis L1 can be the same, for example, increasing or decreasing in sequence. Whether increasing or decreasing in sequence, it brings unique optimization to the air supply effect of the indoor unit 100.
- the projection distance increases in sequence, it focuses on expanding the air supply width and improving air uniformity; when the projection distance decreases in sequence, it focuses on increasing the air supply distance and directionally improving the local environment.
- the projected distances referred to herein are all average distances, calculated from the distances from each point on each air outlet 222a to the center axis of rotation L1.
- the airflow passing through two adjacent crossflow impellers 20 exhibits distinct flow characteristics due to the different trends in the projected distances of the air outlets 222a.
- the airflow is affected by centrifugal force, and as it moves from closer to the center axis of rotation L1 to farther away from it, the velocity and direction of the airflow gradually change, resulting in a more dispersed angle and velocity distribution of the outflowing airflow.
- the volute 11 includes a volute body 111 and a guide rib 112.
- the guide rib 112 is protruded from the volute body 111.
- the guide rib 112 and the volute body 111 can be integrally formed components. This not only enhances the strength of the connection between the guide rib 112 and the volute body 111, but also reduces the number of assembly steps for the guide rib 112 and the volute body 111.
- the guide rib 112 and the volute body 111 can also be separate components, which is not limited in this embodiment.
- a guide groove 113 is defined between two adjacent guide ribs 112. It can be understood that the airflow delivered by the crossflow impeller 20 can flow smoothly to the air outlet under the guidance of the guide ribs 112 and the guide groove 113.
- the air outlet portion 222a of the blade 222 whose air outlet tail end 2221 is opposite to the guide rib 112 is opposite to the guide groove 113, and the air supply cutout 222b of the blade 222 is opposite to the guide rib 112.
- the large vortex in the wake of the airflow discharged from the area of the air outlet tail end 2221 having the air supply cutout 222b is prematurely transformed into multiple small vortices.
- the airflow discharged from the area of the air outlet tail end 2221 not having the air supply cutout 222b i.e., the airflow discharged from the air outlet portion 222a, requires a longer time to transition from a laminar flow state to a turbulent flow state.
- the air-supply slits 222b of different blades 222 of the same cross-flow wind wheel 20 are arranged in a circle along the circumference of the cross-flow wind wheel 20, that is, the air-supply slits 222b of different blades 222 are relatively arranged along the circumference of the cross-flow wind wheel 20, and multiple circles of air-supply slits 222b are arranged along the axial direction L2 of the cross-flow wind wheel 20.
- the air-supply slits 222b of different blades 222 are arranged non-oppositely along the circumference of the crossflow rotor 20, for example, if the air-supply slit 222b of one of two adjacent blades 222 is opposite the air outlet 222a of the other blade 222 along the circumference of the crossflow rotor 20, the phase difference in the impact of the crossflow rotor 20 on the volute tongue 11 will be small during rapid rotation, and there is still a low possibility of resonance.
- each convex rib can be configured to be annular. In this way, the molding of each circle of air-supply cutouts 222b of the multiple blades 222 is achieved through the multiple convex ribs.
- the corresponding convex ribs are continuous and uninterrupted ribs as a whole, thereby making the structural design of the mold simpler, reducing the production cost of the mold, and making it easier to demold and facilitate injection molding production.
- each air-supplying slit 222b parallel to the length direction of the blade 222 is rectangular, triangular or trapezoidal, so that the shape is more regular and the air-supplying slit 222b is easier to process.
- an offset angle A is formed between the adjacent blades 222 of two adjacent groups of blades 222 and the axis of the crossflow impeller 20 in their extension direction, and A is less than or equal to 8 degrees and greater than or equal to 5 degrees.
- A is less than or equal to 8 degrees and greater than or equal to 5 degrees.
- the combination of the form in which the end point line L1L1 is inclined relative to the axial direction L2 of the cross-flow impeller 20, the form in which an air supply cutout 222b is provided on the air outlet tail end 222111, and the form in which the air outlet portion 222a is opposite to the guide groove 113 and the air supply cutout 222b is opposite to the guide rib 112, can achieve a combined noise reduction effect, and more effectively reduce the intensity of the noise generated by the indoor unit 100 during operation.
- each blade 222 does not extend beyond the outer edge of the fixed wall 221. This prevents the outlet ends 2221 of the blades 222 from extending beyond the outer edge of the fixed wall 221, thereby reducing the possibility of injuries to workers caused by touching the outlet ends 2221.
- the number of blades 222 on two adjacent crossflow impellers 20 differs. This ensures that the airflow driven by the two adjacent crossflow impellers 20 reaches the volute 11 at different times, thereby staggering the resonant frequencies and effectively reducing noise intensity.
- the number of blades 222 on the crossflow impeller 20 is 35 to 37. This further facilitates the air intake and sweeping of the blades 222, allowing the crossflow impeller 20 to generate a greater air volume. This reduces the load on the drive motor 50 while maintaining a constant air volume, thereby reducing noise from the indoor unit 100.

参照图1,本申请实施例提出了一种暖通系统,在本申请实施例中,该暖通设备包括但不限于空调、多联机以及热泵等等设备,并且可以应用在商场、写字楼等规模较大的场所。其中,暖通系统可以包括室内机100、室外机(图中未示出)以及连接管(图中未示出),室内机100通过连接管与室外机连接,以使室内机100与室外机构成循环流路。
在一些实际使用场景中,本申请的室内机100可以安装于室内,室外机负责制冷或者制热,并通过连接管运输冷媒或者冷冻水等介质,冷媒或者冷冻水等介质在分别与室内的空气、室外的空气进行热交换后,室内机100负责将冷气或热气输送到室内,以达到降温或升温的效果。
具体地,室内机100可以包括天花机、风管机以及挂壁式空调室内机100中的一种,其中,天花机通常采用吊顶的方式嵌设在天花板内,以通过天花板对天花机起到隐藏效果,如此,使得天花机相较于其他室内机100的形式而言隐藏效果较好,更为美观,本实施例对室内机100的具体形式不作具体限定。
参照图1至图3,在一些实施例中,室内机100包括壳体10、换热器40以及贯流风轮20,换热器40和贯流风轮20均设于壳体10的风道内。
壳体10的外轮廓可以呈矩形块状设置,且壳体10的材质可以为金属材质,以具有强度较佳、轻盈以及耐腐蚀等优点,当然,壳体10的材质还可以为塑料材质,以具有重量轻、成本低、易于加工成型等优点,本实施例对于壳体10的形状以及材质均不作限制。当室内机100安装于室内时,该底面可以位于天花板并朝向室内设置。壳体10的底面间隔设置有进风口10a和出风口10b,且壳体10内部形成有连通进风口10a和出风口10b的风道。如此使得室内机100同一侧进行气流吸入和气流排出,相较于多侧进出风的设计的气流流动路径更为简短,且安装时更方便将进风口10a和出风口10b与室内环境进行连通,减少安装的复杂性。此外,壳体10还包括蜗舌11,蜗舌11位于贯流风轮20和出风口10b之间,蜗舌11用于分割被贯流风轮20送向出风口10b的气流,以使气流的部分能够顺畅流向出风口10b。
换热器40可以呈直线型、V形、弧形或者波浪形等多种形状。换热器40用于与穿过换热器40的气体进行换热,起到对气体进行制冷或制热的作用。例如,换热器40内穿设有多条冷媒管,气体在穿过换热器40时与管内的冷媒换热,从而改变气体温度,具体地,在制冷时气体与换热器40的冷媒热交换形成低温空气,而在制热时气体与换热器40的冷媒热交换形成加热空气。在一些实施例中,换热器40设于风道内,并位于贯流风轮20和进风口10a之间,如此以使得从进风口10a进入的气流会先与换热器40进行换热后,再经过贯流风轮20后从出风口10b吹向室内场景中,如此以使得换热器40远离出风口10b设置,以降低换热器40对出风方向的干涉。
参照图2和图3,在一些结构形式中,壳体10包括机壳12、面板13以及接水盘14。其中,机壳12可选用铝、钢等合金或金属材质,这类材质能够满足对结构强度的要求,确保室内机100具备长时间的使用寿命。当然,机壳12也可采用塑料材质,以实现重量较轻的优势,本申请对机壳12材质不做具体限定。机壳12不仅对内部元件起到保护作用,还能与室内环境的连接结构适配连接。机壳12底部呈敞口设计,面板13覆盖在敞口处,进风口10a和出风口10b在面板13上间隔分布。面板13以可拆卸的方式连接于机壳12底部,这种设计便于在室内机100后期使用中,当机壳12内部的电器元件出现故障时,能够将面板13轻松拆下,进而对机壳12内的电器元件进行检修。面板13与机壳12的连接方式多样,既可以通过螺纹紧固件连接,也可以采用卡扣连接,本申请在此不对其连接方式作具体限制。
换热器40、贯流风轮20以及接水盘14均设置在机壳12内部。机壳12、面板13以及接水盘14相互配合,共同构成风道。接水盘14位于风轮和换热器40的下方,其功能是承接换热器40产生的冷凝水。在室内机100运行过程中,换热器40表面通常会凝结大量冷凝水。一般情况下,为防止过多的冷凝水附着在换热器40表面影响其性能,会在换热器40底部下方设置接水盘14,用于承接这些冷凝水,避免冷凝水对换热器40及室内机100其他部件造成损害,保障室内机100的正常运行。
结合参照图2和图3,贯流风轮20具有节能、风量大、自身运行噪音低、安装简单的优点,从而采用贯流风轮20驱动气流以提高室内机100的使用性能。其中,贯流风轮20可以呈长筒状设置,且贯流风轮20包括叶片222。叶片222的横截面形状可以是呈翼型状,翼型状可以优化气流在叶片222的表面上的分布,使得流经叶片222表面的气流更为均匀,降低了气流在叶片222表面的湍流度,从而提升贯流风轮20的整体气动性能。示例性地,翼型状具体可以是对称翼型、平凸翼型或者凹凸翼型等形状,本实施例对此不作限制。叶片222的材质可以是塑料材质,以具有重量较轻、防腐蚀等优点,例如可以具体为ASG(玻璃纤维强化AS树脂)材质,当然,本实施例不限于此,叶片222的材质还可以是金属材质,以具有强度较高,以保持长久平稳运转而不变形等优点。
然而现有技术的天花机采用贯流风轮20的送风方式较为单一,无法根据不同的室内实际场景而设置适配的送风距离和送风广度,限制了室内机100的使用场景,无法满足实际环境中不同送风需求。
参照图4至图7,基于此,为了解决上述问题,本申请提出至少两贯流风轮20设于风道内,并在出风口10b的长度延伸方向上间隔设置,
其中,在高速旋转或制热工况下,单个长风轮的中部会产生较大的变形,因此在出风口10b的同样长度下,将单个长风轮设计为在出风口10b的长度延伸方向上间隔设置的两个贯流风轮20,以有效降低风轮工作过程中发生变形的可能性。贯流风轮20包括多组叶片222,每一组叶片222具有多个,一组的多个叶片222沿贯流风轮20的旋转中心轴L1的周向间隔排布。沿着垂直于贯流风轮20的轴向L2方向观察,一组叶片222中的每一叶片222相对于轴向L2方向倾斜设置。具体而言,在实际加工过程中,可以包括以下至少两种实现各个叶片222自身相对于轴向方向倾斜设置的加工形式:
第一种形式中,叶片222为塑料材质,且通过注塑成型的形式加工形成,而在脱模过程中,可以采用旋转脱模的形式,具体为在脱模过程中,使模具沿着旋转轴线旋转,从而在脱模过程中形成相对于轴向的倾斜形态;
第二种形式中,在加工出叶片222后,仅对叶片222沿其长度方向的任一一端施加外力,使叶片,222形成相对于轴向的倾斜;或者对叶片222沿其长度方向的一端施加沿顺时针方向的外力,另一端施加逆时针方向的外力,以此使叶片222形成相对于轴向的倾斜形态。
综上,将进风口10a和出风口10b均设置在壳体10的底面,如此使得室内机100同一侧进行气流吸入和气流排出,相较于多侧进出风的设计的气流流动路径更为简短,且安装时更方便将进风口10a和出风口10b与室内环境进行连通,减少安装的复杂性。其次,在室内机100同一侧设置进出风的基础上,而倾斜设置的叶片222可改变气流方向与速度,进而能够根据室内实际场景,通过调整叶片222倾斜角度以及多个贯流风轮20的协同运转,实现对送风距离和送风广度的灵活调节,拓宽了室内机100的使用场景,满足了实际环境中多样化的送风需求,在室内空气环境优化、提升人体舒适性以及助力室内机100节能方面具有积极意义。
参照图6和图7,在一结构形式中,相邻两贯流风轮20的叶片222的倾斜方向相同。这能使相邻贯流风轮20对气流产生同向的导向作用。在风道内,气流受相邻贯流风轮20同向导向影响,可形成更集中、稳定的气流束。这种集中稳定的气流束在通过出风口10b时,能够增强送风的方向性,进而有效增加送风距离。同时,由于气流集中,可减少气流在扩散过程中的能量损失,有助于室内机100节能。此外,集中的气流还能在一定程度上提高室内特定区域的空气循环速度,优化室内空气环境,提升人体的舒适感。而且这种结构相较于叶片222倾斜方向复杂多变的设计,在制造和装配过程中更为简便,降低了生产难度和成本。
参照图4和图5,在另一种结构形式中,相邻两贯流风轮20的叶片222的倾斜方向不同。如此使得流经这两个贯流风轮20的气流受到不同方向的导向作用。当气流依次经过倾斜方向各异的相邻贯流风轮20时,会产生方向和速度的差异化变化,进而在出风口10b处形成复杂且多元的气流组合。这种多样化的气流组合极大地拓展了送风广度,能够更全面地覆盖室内空间,确保各个角落都能得到有效的空气调节。同时,由于气流在不同方向上的混合与交织,室内空气的循环更为充分,能有效避免出现空气调节死角,进一步优化室内空气环境,提升整体的人体舒适性。此外,不同方向的气流相互作用,可在一定程度上扰乱气流边界层,减少气流分离现象,提高了气流输送效率,有助于实现室内机100在不同送风模式下的节能运行。
参照图8至图11,在一些结构形式中,每一贯流风轮20具有沿着轴向L2方向间隔设置的多个固定壁221,每相邻两个固定壁221之间具有一组叶片222。其中,叶片222可通过超声波焊接的方式牢固地固定于固定壁221上,这种焊接方式能够保证叶片222与固定壁221之间连接的稳定性,确保在贯流风轮20高速旋转时,叶片222不会松动或脱落,从而保障贯流风轮20稳定、高效地工作。贯流风轮20的叶片222具有远离贯流风轮20的旋转中心轴的出风尾端2221,可以理解的是,气流在流经叶片222时,最终会由出风尾端2221流出,并流向蜗舌11。
参照图5,在一些结构形式中,室内机100还包括联轴器30,联轴器30连接于两相邻贯流风轮20之间。通过联轴器30以将两个相邻的贯流风轮20进行连接在一起,使它们能够同步运行。这样一来,系统可以通过同一个驱动电机50来驱动两个贯流风轮20,而不是需要两个独立的驱动电机50。这种设计不仅减少了系统的能源消耗,还降低了系统的维护成本。其次,联轴器30连接两个贯流风轮20的设计简化了系统的结构,减少了零部件的数量和复杂性。这有助于提高系统的可靠性和稳定性,减少了故障的可能性。参照图10和图11,此外,在贯流风轮20的相对两端分别设有端盖21,端盖21上开设有连接孔,以便于与联轴器30或者驱动电机50连接。
结合参照图5、图12以及图13,进一步地,室内机100还包括支撑座60和缓冲构件70,支撑座60用于支撑联轴器30,缓冲构件70连接于支撑座60朝向换热器40的一侧,以与换热器40弹性抵接。支撑座60主要承担支撑联轴器30的作用,确保联轴器30在运行过程中保持稳定。而缓冲构件70则连接于支撑座60朝向换热器40的一侧,其功能是与换热器40实现弹性抵接。缓冲构件70通常采用硅胶或者橡胶材质。硅胶材质具有良好的柔韧性、耐候性和绝缘性。其柔韧性能够使其在受到震动冲击时,发生弹性形变,有效吸收和分散震动能量,避免震动传递至换热器40,保护换热器40的内部结构不受震动损害;耐候性使其在不同的环境条件下,如温度、湿度变化较大的室内环境中,依然能保持稳定的缓冲性能,不会因环境因素而迅速老化变质。橡胶材质同样具有出色的弹性,能够快速回弹,有效缓冲震动。而且橡胶还具备一定的耐磨性,在长期频繁的震动缓冲过程中,不易出现磨损,确保了缓冲构件70的使用寿命。当室内机100运行时,可能会产生震动,由硅胶或橡胶制成的缓冲构件70能够有效缓冲这种震动,减少联轴器30与换热器40之间因震动而产生的相互影响,进一步提升系统运行的稳定性,保护换热器40及其他相关部件,延长室内机100的整体使用寿命。
参照图8和图14,在一些结构形式中,出风尾端2221包括多个间隔设置的出风部222a,相邻的两个出风部222a之间限定出补气切口222b,补气切口222b被配置为使补气切口222b处的气流从层流状态向湍流状态过渡。从而在气流流向蜗舌11过程中,能够让位于气流的尾迹的大涡流提前变成多个小涡流,如此,不仅能够降低气流在流向蜗舌11过程中所产生的噪音的强度,而且在多个小涡流冲击蜗舌11的形式中,相较于大涡流冲击蜗舌11的形式,所产生的噪音的强度会更低。
结合参照图15,在一些实施例中,沿着垂直于贯流风轮20的轴向L2方向观察,每一组中的每一叶片222中的多个出风部222a到旋转中心轴L1的投影距离依序增大。需要说明的是,这里的投影距离指的是多个出风部222a到旋转中心轴L1的平均距离,即对每个出风部222a上各点到旋转中心轴L1的距离进行综合计算得出的平均数值依序增大。当贯流风轮20运转时,由于多个出风部222a到旋转中心轴L1的平均投影距离呈依序增大的态势,气流在流经叶片222时,会受到不同程度的离心力作用。靠近旋转中心轴L1的出风部222a,气流受到的离心力相对较小,而随着平均投影距离增大,出风部222a对应的气流所受离心力逐渐增大。这使得气流在叶片222表面的流动速度和方向产生差异化变化,进而改变了气流流出叶片222时的角度和速度分布。
从送风效果来看,这种差异化的气流输出,能够在出风口10b处形成更为复杂且多样化的气流组合。一方面,扩大了送风广度,使得室内空间中更大范围的区域能够被气流覆盖,避免出现送风死角,优化室内空气的均匀性;另一方面,不同速度和角度的气流相互交织,有助于增强气流在室内的扩散能力,提升空气循环效率,从而提高室内机100对空气的调节能力,为用户营造更为舒适的室内空气环境。
参照图7和图16,在另一实施例中,沿着垂直于贯流风轮20的轴向L2方向观察,每一组中的每一叶片222中的多个出风部222a到旋转中心轴L1的投影距离依序减小。如此当贯流风轮20处于运转状态时,由于多个出风部222a到旋转中心轴L1的平均投影距离依序减小,气流在流经叶片222的过程中,所受离心力的变化趋势与平均投影距离增大的情况相反。距离旋转中心轴L1较远的出风部222a,气流起初受到较大的离心力作用,随着平均投影距离逐渐减小,气流所受离心力也随之减弱。这种离心力的变化致使气流在叶片222表面的流动状态发生改变,其速度和方向产生差异化的调整,进而使得气流流出叶片222时的角度和速度分布呈现出独特的模式。
从送风效果层面分析,这种差异化的气流输出模式能够在出风口10b处形成别具一格的气流组合。与平均投影距离依序增大的情况不同,在此种设计下,气流更趋向于集中向特定区域输送,有助于显著增加送风距离,使得室内机100能够将气流送达距离较远的空间位置,在一些较大空间的场所,如商场、大型会议室等,能够有效实现远距离的空气输送与调节。同时,由于气流相对集中,在特定方向上的气流强度得以增强,这对于定向改善局部区域的空气环境质量具有重要意义,比如在一些对局部温度、湿度等环境参数要求较高的区域,能够更精准地满足需求。在节能方面,通过巧妙地利用这种平均投影距离依序减小所带来的气流变化,室内机100能够以更为高效的方式输送气流。在满足特定送风距离和局部区域空气调节需求的同时,减少了不必要的能量损耗,实现了能源的优化利用。相比于传统的送风结构,在达到相同送风效果的情况下,能耗得以降低,这不仅符合当前社会对于节能环保的倡导,也为用户在长期使用过程中节省了运行成本。
进一步而言,沿着垂直于贯流风轮20的轴向L2方向观察,每一组中的每一叶片222中的多个出风部222a到旋转中心轴L1的投影距离变化可以相同,例如依序增大或者依序减小。无论是依序增大还是依序减小,都为室内机100的送风效果带来了独特的优化。投影距离依序增大时侧重于扩大送风广度与提升空气均匀性;投影距离依序减小时则着重于增加送风距离与定向改善局部环境。这两种设计方式为适应不同的室内空间环境和用户需求提供了多样化的选择,有助于提升室内机100的整体性能和适用性,更好地满足人们对舒适室内空气环境的追求。
结合参照图5、图15以及图16,在另一些实施例中,沿着垂直于贯流风轮20的轴向L2方向观察,相邻的两个贯流风轮20,其中一个贯流风轮20的每一组中的每一叶片222中的多个出风部222a到旋转中心轴L1的投影距离依序增大,另一个贯流风轮20的的每一组中的每一叶片222中的多个出风部222a到旋转中心轴L1的投影距离依序减小。
其中,这里所涉及的投影距离均为平均距离,是对每个出风部222a上各点到旋转中心轴L1的距离综合计算得出的数值。当室内机100运行时,两个相邻贯流风轮20因出风部222a投影距离变化趋势不同,会使流经它们的气流产生截然不同的流动特性。对于出风部222a投影距离依序增大的贯流风轮20,气流受离心力影响,从靠近旋转中心轴L1到远离旋转中心轴L1的过程中,速度和方向变化逐渐加剧,导致流出的气流角度和速度分布更为分散,这有助于扩大送风广度,使室内更大范围的区域能被气流覆盖,有效避免送风死角,促进室内空气的均匀混合。而对于出风部222a投影距离依序减小的贯流风轮20,气流在从远离旋转中心轴L1流向靠近旋转中心轴L1的过程中,所受离心力逐渐减弱,气流流出时更趋于集中,能够显著增加送风距离,特别适合在大型空间内将气流输送到较远位置。当这两个特性不同的贯流风轮20协同工作时,在出风口10b处能够形成极为复杂且互补的气流组合。不仅能同时兼顾送风广度和送风距离,满足不同空间区域的空气调节需求,如在宽敞的客厅中,既可以让角落处也能感受到舒适的气流,又能在长条形的空间内实现有效通风;还能通过气流的相互作用,进一步增强室内空气的循环效率。不同速度和方向的气流相互碰撞、交织,加速了空气的混合与交换,使室内温度、湿度等环境参数更加均匀稳定,极大地提升了人体的舒适感。从节能角度来看,这种设计优化了气流的输送方式,根据不同空间需求精准分配能量。在满足复杂空间空气调节的同时,避免了不必要的能量浪费,提高了能源利用效率。相较于传统单一模式的送风系统,在实现相同舒适环境的前提下,能够降低能耗,为用户节省长期的使用成本,同时也响应了节能环保的社会发展趋势,具有显著的经济效益和环境效益。
参照图14,在一些实施例中,蜗舌11包括蜗舌主体111和导流筋112,导流筋112凸设于蜗舌主体111上,其中,导流筋112与蜗舌主体111可以为一体成型构件,如此不仅能够增强导流筋112与蜗舌主体111之间连接的强度,还能够减少导流筋112与蜗舌主体111的组装步骤,当然,导流筋112与蜗舌主体111还可以为分体构件,本实施例对此不作限制。导流筋112的数量为多个,多个导流筋112间隔地凸设于蜗舌主体111上,相邻两个导流筋112之间限定出导流槽113。可以理解的是,贯流风轮20所送出的气流在导流筋112与导流槽113的导引下能够顺畅地流向送风口。
其中,在贯流风轮20转动至任一角度的状态下,沿贯流风轮20的出风方向,出风尾端2221与导流筋112相对的叶片222的出风部222a与导流槽113相对,且,该叶片222的补气切口222b与导流筋112相对。
可以理解的是,由出风尾端2221具有补气切口222b的区域所送出的气流,位于其尾迹的大涡流提前变成多个小涡流,而由出风尾端2221未具有补气切口222b的区域,也即由出风部222a所送出的气流,其流动状态若要从层流状态向湍流状态过渡,所需的流动时间较长。因此,在受限于室内机100的尺寸一定,而使蜗舌11与贯流风轮20之间的相对距离无法拉远的基础上,通过导流槽113与出风部222a进行相对,能够适当延长由出风部222a流出的气流流向蜗舌11的距离,使得由出风部222a流出的气流在冲击至导流槽113的槽底壁之前,位于其尾迹的大涡流提前变成多个小涡流,从而能够进一步降低噪音的强度。如此,在该实施例中,结合端点连线L1L1相对于贯流风轮20的轴向L2倾斜的形式、以及在出风尾端2221上设置有补气切口222b的形式,能够起到组合降噪的效果,更为有效地降低了室内机100在运行过程中产生的噪音的强度。
进一步地,同一贯流风轮20的不同叶片222的补气切口222b沿其贯流风轮20的周向排布呈一圈,也即,不同叶片222的补气切口222b沿贯流风轮20的周向呈相对设置,且多圈补气切口222b沿贯流风轮20的轴向L2排布。
一方面,基于降噪的角度,若不同叶片222的补气切口222b沿贯流风轮20的周向非相对设置,例如沿贯流风轮20的周向,相邻两个叶片222中,其中一个叶片222的补气切口222b与其中另一个叶片222的出风部222a相对,会导致贯流风轮20在快速转动过程中,对蜗舌11的冲击相位所存在差异较小,仍存在低可能性会出现共振。基于此,通过不同叶片222的补气切口222b沿贯流风轮20的周向排布呈一圈,能够使得贯流风轮20在快速转动过程中对蜗舌11的冲击相位所存在差异较大,进一步降低出现共振的可能性,更为有效地降低噪音的强度。
另一方面,基于生产制造的角度,当叶片222为塑料材质且在对叶片222进行注塑制造时,可以通过在用于生产叶片222的模具的模腔内凸设有多条间隔排布的凸筋,且每条凸筋可以被配置为环状,如此,通过多条凸筋实现多个叶片222的每一圈补气切口222b的成型,而当属于同一圈的多个补气切口222b在周向上相对时,对应的凸筋整体是连续且不间隔的筋体,从而使得模具的结构设计更为简单,降低模具的生产成本,且能够更便于进行脱模,方便注塑生产。
可选地,每一补气切口222b的与叶片222的长度方向平行的横截面形状呈矩形、三角形或者梯形。如此使得形状较为规则,便于加工出补气切口222b。
参照图8,在一些实施例中,相邻的两组叶片222上,相邻的两叶片222在二者的延伸方向上与贯流风轮20的轴线之间存在错位角A,A小于等于8度,且大于等于5度。如此,通过形成错位角A,以使得相邻的两节的风轮中节22会错开送风,使得相邻的两节的风轮中节22的叶片222所送出的气流会在不同时刻冲击到蜗舌11上,在通过蜗舌11处时对蜗舌11的冲击相位会存在差异,使得频谱特征呈离散状,不易出现共振,有效降低噪音的强度。并且,在该实施例中,结合端点连线L1L1相对于贯流风轮20的轴向L2倾斜的形式、在出风尾端222111上设置有补气切口222b的形式以及出风部222a与导流槽113相对且补气切口222b与导流筋112相对的形式,能够起到组合降噪的效果,更为有效地降低了室内机100在运行过程中产生的噪音的强度。
可选地,在贯流风轮20的径向上,各个叶片222不伸出固定壁221的外边缘。如此能够避免叶片222的出风尾端2221伸出固定壁221的外边缘,降低工作人员因碰触出风尾端2221而造成划伤的可能性。
可选地,相邻两贯流风轮20的叶片222数量不同。如此以使得相邻的两个贯流风轮20驱动的气流到达蜗舌11的时间点不同,以错开共振频率。有效降低噪音的强度。其中,贯流风轮20的叶片222数量为35片至37片,如此,可进一步有利于叶片222的进风与扫风,使得贯流风轮20能产生更大的风量,从而在风量一定的条件下,降低驱动电机50的负荷,进而使得室内机100的噪音得以降低。
