技术领域Technical field
本发明涉及空调技术领域，特别涉及一种送风***及应用其的室内机和空调。The invention relates to the technical field of air conditioners, in particular to an air supply system and an indoor unit and an air conditioner using the same.
背景技术Background technique
为了增大风量以提高换热效果，目前已经设计出了新型的空调，其具有多个风机经由同一个出风口进行出风。但是经过实践发现，采用现有结构中多个风机的送风***配合方式，其出风效果还不是十分理想。In order to increase the air volume to improve the heat exchange effect, a new type of air conditioner has been designed, which has multiple fans to perform air through the same air outlet. However, it has been found through practice that the air supply effect of multiple fans in the existing structure is not very satisfactory.
以常见的立式空调柜机为例，如图1所示，其由三个离心风机纵向排列组合而成，横向从后侧吸风，因其中的上风机1和中风机2风向均要纵向往上输送到头部上风口，为了保证中风机2有单独的出风空间，上风机1和中风机2这两者的出风道是错开设计的：上风机1可以直接出风，中风机2向上出风需要避开上风机1风道结构，因此斜上方向开了风口，使得中风机2出风方向与上风机1结构纵向方向错开。Taking a common vertical air conditioner cabinet as an example, as shown in Fig. 1, it is composed of three centrifugal fans arranged longitudinally, and the wind is sucked laterally from the rear side, because the wind direction of the upper fan 1 and the middle fan 2 are both longitudinal. It is transported up to the upper air outlet of the head. In order to ensure that the air blower 2 has a separate air outlet space, the air outlets of the upper fan 1 and the middle fan 2 are staggered: the upper fan 1 can directly discharge air, and the middle fan 2 The upward air outlet needs to avoid the air duct structure of the upper fan 1, so that the air outlet is opened obliquely upward, so that the air outlet direction of the middle fan 2 is shifted from the longitudinal direction of the upper fan 1 structure.
上中风机的风路示意可以参照图3所示，在出风口汇集后总风向斜向上吹出，从而导致空调上出风口出风整体偏上。这样一来，在空调制热运行时，将会导致热风无法向下送，导致制热房间下层温度低，温度层不均匀。The wind path of the upper middle fan can be referred to as shown in Fig. 3. After the air outlets are collected, the total wind direction is blown upwards, which causes the air outlet of the air conditioner to be entirely upward. In this way, during the heating operation of the air conditioner, the hot air cannot be sent downward, resulting in a low temperature in the lower layer of the heating room and uneven temperature layer.

Under the influence of the wall effect, the direction of the second fan's air outlet is adjusted.

Front, the air outlet facing away from the casing is backward.
为了便于理解，下面以第一风机为上风机1，第二风机为中风机2，两者均向设备壳体的上出风口送风为例进行说明，其他形式同理。现有结构的风路如图1所示，为了避开上风机1风道，中风机2出风方向为直接朝着出风口倾斜往上，即朝前(在此以壳体开设出风口的一侧为前，即图中右侧，另一侧为后，即图中左侧，下同)。而在本方案中，其风路如图2所示，导风机构4能够将中风机2的出风方向调整为背向壳体上出风口，即朝后；又直接出风的上风机1出风位置是在壳体内后方的；因此如图4所示，中风机2出风在导风机构4的作用下过渡性的调整方向(朝后)后，就会与上风机1出风汇集，并在壳体内附壁效应的影响下由竖直向上转变为平面向前吹出；后续再利用出风口导风板按 需求实现斜向上出风、水平出风或斜向下出风，从而解决原有风道上中风机分别送风在出风口时的风向不一而导致出风口风向偏上的问题。For ease of understanding, the first fan is the upper fan 1 and the second fan is the middle fan 2, both of which are sent to the upper air outlet of the device housing as an example, and other forms are similar. The wind path of the existing structure is as shown in Fig. 1. In order to avoid the air passage of the upper fan 1, the air outlet direction of the middle fan 2 is inclined upwards directly toward the air outlet, that is, facing forward (here, the air outlet is opened by the casing One side is the front, that is, the right side of the figure, and the other side is the back, that is, the left side in the figure, the same below). In this solution, the air path is as shown in FIG. 2, and the air guiding mechanism 4 can adjust the air blowing direction of the middle fan 2 to the air outlet facing away from the casing, that is, facing backward; The air outlet position is in the rear of the casing; therefore, as shown in FIG. 4, after the air blow of the middle fan 2 is in a transitional direction (backward) by the air guiding mechanism 4, the wind is collected from the upper fan 1 And under the influence of the wall effect in the shell, it is converted from a vertical upward to a flat forward; the subsequent use of the air outlet guide The demand realizes the oblique upward air outlet, the horizontal air outlet or the oblique downward air outlet, thereby solving the problem that the wind direction of the air outlet on the original air duct is different when the air is separately supplied to the air outlet, thereby causing the wind direction of the air outlet to be upward.
为了进一步优化上述的技术方案，导风机构4具有用于调整风向的内弧面，其形状形成一定弧度向内，起到调整第二风机出风方向的作用；与其他曲面导向结构相比，弧面能够使得第二风机出风缓慢并入第一风机出风，以避免风向调整过于急促加大风阻且容易与壳体风口出风形成干涉。In order to further optimize the above technical solution, the air guiding mechanism 4 has an inner arc surface for adjusting the wind direction, and the shape thereof forms a certain arc inward to adjust the air outlet direction of the second fan; compared with other curved guiding structures, The curved surface enables the second fan to slowly merge into the first fan to prevent the wind direction from being adjusted too rapidly to increase the wind resistance and easily interfere with the air outlet of the casing.
在本方案提供的具体实施例中，导风机构4内弧面上的各点均位于同一球面，对风向过渡效果良好，且便于加工得到。导风机构4可以整体为球形圆弧结构，如图5-图7所示；除了上述开放式结构之外，导风机构4还可以采用相对封闭的弯管方式。考虑到设备壳体内复杂的装配环境，作为优选，导风机构4的边缘设置有缺口，形成让位结构，以避免与其他零部件的干涉。In the specific embodiment provided by the solution, each point on the inner arc surface of the air guiding mechanism 4 is located on the same spherical surface, and the wind direction transition effect is good, and is convenient for processing. The air guiding mechanism 4 can be a spherical arc structure as a whole, as shown in FIG. 5 to FIG. 7; in addition to the above-mentioned open structure, the air guiding mechanism 4 can also adopt a relatively closed bending mode. In view of the complicated assembly environment in the equipment casing, preferably, the edge of the air guiding mechanism 4 is provided with a notch to form a seating structure to avoid interference with other components.
导风机构4设计具有向空调内(即后)侧方向一定弧度，该弧度设计不宜过大，作为优选，导风机构4的内弧面其对应的弧度建议不大于30°，以使得第二风机出风以适宜的速度(缓慢)和方向并入第一风机出风，以避免风向调整过于急促加大风阻且容易与上风口出风形成干涉。The air guiding mechanism 4 is designed to have a certain arc toward the inner (ie, rear) side of the air conditioner, and the arc design is not excessively large. Preferably, the inner arc surface of the air guiding mechanism 4 has a corresponding arc of not more than 30°, so that the second The fan air is merged into the first fan at a suitable speed (slowly) and direction to avoid the wind direction adjustment is too rapid to increase the wind resistance and easily interfere with the air outlet.
为了进一步优化上述的技术方案，导风机构4设置在在第一风机的风道出口位置处，以实现对第二风机出风方向的更好调整，并使其与第一风机出风汇集后的出风方向更接近理想方向。In order to further optimize the above technical solution, the air guiding mechanism 4 is disposed at the air duct outlet position of the first fan to achieve better adjustment of the air outlet direction of the second fan, and after being combined with the first fan. The direction of the wind is closer to the ideal direction.
在本方案提供的具体实施例中，第一风机为离心风机，导风机构4的出口连通于离心风机的蜗壳出风口扩压段。如此一来，第二风机出风到达第一风机蜗壳出风口扩压段缺口位置时，受第一风机出风作用，被吸入第一风机出风口扩压段，并在附壁效应的影响下改变气体流动方向；同时因为第一风机蜗壳出风口扩压段缺口的设计，使得第二风机出风空间增大，进而提升第二风机风量。In the specific embodiment provided by the solution, the first fan is a centrifugal fan, and the outlet of the air guiding mechanism 4 is connected to the diffuser section of the volute outlet of the centrifugal fan. In this way, when the second fan reaches the gap position of the diffuser section of the first fan volute outlet, the first fan is taken out by the wind, and is sucked into the diffuser section of the first fan outlet, and the influence of the Coanda effect The gas flow direction is changed downward; at the same time, because of the design of the gap of the diffuser section of the air outlet of the first fan volute, the air volume of the second fan is increased, thereby increasing the air volume of the second fan.
导风机构4的出口与离心风机的蜗壳出风口扩压段的连通可以采用管道连接的方式。为了进一步优化上述的技术方案，导风机构4为设置在在第一风机的风道出口位置处的弧形件，第一风机的蜗壳出风口扩压段开设有缺口，即导风机构4的出口通过上述缺口导向离心风机的出风口扩压段。本实施例通过上述连通方式，避免了实体连接管道，结构简单，对于设备壳体内部空间占用小，没有增加过多风阻，易于加工实现，能够在现有产品上直接改造。 The connection between the outlet of the air guiding mechanism 4 and the diffuser section of the volute outlet of the centrifugal fan may be connected by a pipe. In order to further optimize the above technical solution, the air guiding mechanism 4 is an arc-shaped member disposed at the air duct outlet position of the first fan, and the diffuser section of the volute air outlet of the first fan is provided with a gap, that is, the air guiding mechanism 4 The outlet is guided to the diffuser section of the air outlet of the centrifugal fan through the above gap. In the embodiment, the connection mode is adopted to avoid the physical connection of the pipeline, the structure is simple, the internal space of the equipment casing is small, the wind resistance is not increased, the processing is easy, and the existing product can be directly modified.

The air deflector realizes an oblique upward air outlet, a horizontal air outlet or a diagonal downward air outlet as required. Preferably, the air guiding mechanism 4 is fixed to the upper air outlet support base, and specifically can be connected by screws, screws or buckles.
