Description
技术领域 technical field
本发明涉及空调的设计领域，尤其涉及一种空调室内机及空调。The invention relates to the design field of air conditioners, in particular to an air conditioner indoor unit and an air conditioner.
背景技术 Background technique
蒸发器是空调室内机的关键设备之一，经过蒸发器的气流将直接用于房内的发热设备，是系统制冷效果最直接的表现，因此蒸发器的设计是室内机设计的关键。在相同的制冷需求下，提高蒸发器的换热效率，可以使系统所需要蒸发器的面积减小，节省成本；或者在相同的蒸发器面积的情况下，减小换热所需的风量，减小了风机的负荷，达到了节能的效果。The evaporator is one of the key equipment of the indoor unit of the air conditioner. The airflow passing through the evaporator will be directly used for the heating equipment in the room, which is the most direct manifestation of the cooling effect of the system. Therefore, the design of the evaporator is the key to the design of the indoor unit. Under the same cooling demand, improving the heat exchange efficiency of the evaporator can reduce the area of the evaporator required by the system and save costs; or in the case of the same evaporator area, reduce the air volume required for heat exchange, The load of the fan is reduced, and the effect of energy saving is achieved.
受室内机紧凑空间的限制，空调室内机的蒸发器往往呈倾斜型、“A”型、“V”型摆放以增大换热面积。进风方向与蒸发器迎风面之间并不垂直，而是成一定的夹角，造成蒸发器从上往下(下送风方式)的迎面风速不均匀，以空调室内机下送风，蒸发器呈“A”型摆放为例，蒸发器靠近进风口的上部的风速较小，远离进风口的下部的风速较大，影响蒸发器的换热效率。Limited by the compact space of the indoor unit, the evaporator of the indoor unit of the air conditioner is often placed in an inclined, "A" or "V" shape to increase the heat exchange area. The air inlet direction is not perpendicular to the windward side of the evaporator, but forms a certain angle, resulting in uneven wind speed on the face of the evaporator from top to bottom (downward air supply mode). For example, if the evaporator is arranged in "A" shape, the wind speed at the upper part of the evaporator close to the air inlet is relatively small, and the wind speed at the lower part away from the air inlet is relatively high, which affects the heat exchange efficiency of the evaporator.
目前经过蒸发器的风速不均匀问题改善方式较少，其中一种为优化蒸发器的流路，但对变工况的适应能力较差；一种为改变蒸发器迎风面与进风方向的夹角，使进风方向垂直或近似垂直于蒸发器迎风面，这种方案往往会带来室内机架构大范围的更改，而且受室内机空间的限制，往往达不到相应的效果。At present, there are few ways to improve the problem of uneven wind speed passing through the evaporator. One of them is to optimize the flow path of the evaporator, but its adaptability to changing working conditions is poor; Angle, so that the air inlet direction is perpendicular or nearly perpendicular to the windward side of the evaporator. This solution often brings about a large-scale change in the structure of the indoor unit, and due to the limitation of the space of the indoor unit, it often fails to achieve the corresponding effect.

具体实施方式 Detailed ways
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
一方面，如图1、图2、图4-图7所示，本发明实施例提供了一种空调室内机，包括：外壳，在所述外壳上设置的进风口和出风口，以及设置在所述外壳内侧的蒸发器；还包括：导流板；On the one hand, as shown in Fig. 1, Fig. 2, Fig. 4-7, an embodiment of the present invention provides an air conditioner indoor unit, comprising: a casing, an air inlet and an air outlet arranged on the casing, and a The evaporator inside the shell; also includes: a deflector;
所述导流板置于所述进风口与所述蒸发器之间，且与所述蒸发器间留有空隙；这样，通过进风口的进风才能够由空隙吹向蒸发器的迎风面的下部。The deflector is placed between the air inlet and the evaporator, and there is a gap between the evaporator and the evaporator; in this way, the air entering through the air inlet can be blown from the gap to the windward side of the evaporator. lower part.
所述导流板的迎风面与所述进风口的进风相对，且所述导流板的顶端到靠近该导流板的所述蒸发器的迎风面的垂直距离d1大于所述导流板的底端到所述蒸发器的迎风面的垂直距离d2。The windward side of the deflector is opposite to the air inlet of the air inlet, and the vertical distance d1 from the top of the deflector to the windward side of the evaporator close to the deflector is greater than that of the deflector The vertical distance d2 from the bottom end of the evaporator to the windward side of the evaporator.
需要说明的是，上述空调为室内机，室内空气由进风口进入，一部分直接穿过蒸发器的迎风面，另一部分经导流板的阻挡到达并穿过蒸发器的迎风面。其中，本发明所有实施例中，将导流板分为两个面，将进风口的进风能够直接吹到的一面称为该导流板的迎风面，另一面称为该导流板的背风面。上述导流板的迎风面与进风口的进风相对，具体是指：通过进风口的进风能够直接到达导流板的迎风面。It should be noted that the above-mentioned air conditioner is an indoor unit, and indoor air enters through the air inlet, part of which directly passes through the windward side of the evaporator, and the other part reaches and passes through the windward side of the evaporator through the blocking of the deflector. Wherein, in all embodiments of the present invention, the deflector is divided into two surfaces, and the side where the air inlet can be directly blown to is called the windward side of the deflector, and the other side is called the windward side of the deflector. Leeward side. The above windward side of the deflector is opposite to the air intake of the air inlet, which specifically means that the incoming wind through the air inlet can directly reach the windward side of the deflector.
另外，上述的导流板的顶端指靠近进风口，且不是迎风面或背风面的上端面；导流板的底端指远离进风口，且不是迎风面或背风面的下端面。In addition, the top of the deflector refers to the upper end surface close to the air inlet and not the windward side or the leeward side; the bottom end of the deflector refers to the lower end surface away from the air inlet and not the windward side or the leeward side.
本发明提供的空调室内机，通过增设的导流板，增大了穿过蒸发器的迎风面上部的风速，减少了穿过蒸发器的迎风面下部的风速，也就是说，改善了穿过空调室内机中蒸发器的气流组织，使穿过蒸发器的风速分布更加均匀，从而能够改善蒸发器的换热效率，进而节省了空调用电量。The air-conditioning indoor unit provided by the present invention increases the wind speed passing through the upper part of the windward side of the evaporator and reduces the wind speed passing through the lower part of the windward side of the evaporator through the additional deflector, that is to say, improves the wind speed passing through The airflow organization of the evaporator in the indoor unit of the air conditioner makes the distribution of the wind speed passing through the evaporator more uniform, thereby improving the heat exchange efficiency of the evaporator, thereby saving the electricity consumption of the air conditioner.
上述导流板可以是不透风的，任意形状的板子。示例的，其形状可以参考下面的实施例。Above-mentioned deflector can be airtight, the plate of arbitrary shape. For example, its shape can refer to the following embodiments.
空调室内机中的蒸发器通常呈倾斜型、“A”型或“V”型摆放，图1、图2、图4、图5所示的空调室内机以蒸发器呈“A”型摆放为例，图6所示的空调室内机以蒸发器呈“V”型摆放为例，图7所示的空调室内机以倾斜型为例。此外，图1至图7都为下送风方式，但对于本发明来说，不仅适用于下送风方式，也适用于上送风方式。The evaporator in the indoor unit of the air conditioner is usually placed in an inclined, "A" or "V" shape, and the indoor unit of the air conditioner shown in Figure 1, Figure 2, Figure 4, and Figure 5 is arranged with the evaporator in an "A" shape. As an example, the air conditioner indoor unit shown in Figure 6 takes the evaporator in a "V" shape as an example, and the air conditioner indoor unit shown in Figure 7 takes an inclined type as an example. In addition, Fig. 1 to Fig. 7 all show the downward air supply mode, but for the present invention, it is not only applicable to the downward air supply mode, but also applicable to the upward air supply mode.
可选的，如图1、6、7所示，所述导流板为一个平直板。Optionally, as shown in Figures 1, 6 and 7, the deflector is a straight plate.
可选的，所述导流板为折面形状，所述折面由至少两个平直板组成的。示例的，如图2所示，折面由两个平直板组成，这种情况下，两个平直板中间的交线可以凸向蒸发器的迎风面，也可以凹向蒸发器的迎风面，图示中以前者为例。Optionally, the deflector is in the shape of a folded surface, and the folded surface is composed of at least two straight plates. For example, as shown in Figure 2, the folding surface is composed of two straight plates. In this case, the intersection line between the two straight plates can be convex to the windward side of the evaporator, or can be concave to the windward side of the evaporator. In the illustration, the former is taken as an example.
进一步优选的，以所述导流板上部的平直板作为参考平面，所述导流板从上部到底部的各个平直板的倾斜角度依次增大；其中任一个平直板的倾斜角度是指：该平直板与参考平面之间的夹角。示例的，若折面由两个平直板组成，则图2中所示的导流板作为优选方案，该导流板从上部到底部的两个平直板的倾斜角度依次用a1和a2表示，且a1＝0，a2＞0，显然，a2＞a1。这样更有利于增大蒸发器上部风速，使蒸发器上下部风速分布均匀。Further preferably, with the straight plate on the top of the deflector as a reference plane, the inclination angles of each straight plate of the deflector from the upper part to the bottom increase sequentially; wherein the inclination angle of any straight plate refers to: the The angle between the flat plate and the reference plane. For example, if the folding surface is composed of two straight plates, the deflector shown in Figure 2 is the preferred solution, and the inclination angles of the two straight plates from the top to the bottom of the deflector are represented by a1 and a2 in sequence, And a1=0, a2>0, obviously, a2>a1. This is more conducive to increasing the wind speed at the upper part of the evaporator, so that the wind speed distribution at the upper and lower parts of the evaporator is even.
此处所述的导流板的上部为靠近进风口的平直板，底部为离进风口最远的平直板。The upper part of the deflector described here is a straight plate close to the air inlet, and the bottom is a straight plate farthest from the air inlet.
可选的，如图4所示，所述导流板为弧面形状。该弧面形状的导流板的开口处可以正对所述蒸发器的迎风面，也就是说，该弧面形状的导流板凹向所述蒸发器的迎风面。但是，在本发明实施例中优选为，该弧面形状的导流板的开口处背对所述蒸发器的迎风面，也就是说，该弧面形状的导流板凸向所述蒸发器的迎风面；这样，使得穿过蒸发器迎风面的风速分布更加均匀。Optionally, as shown in FIG. 4 , the deflector is in an arc shape. The opening of the arc-shaped deflector may face the windward side of the evaporator, that is, the arc-shaped deflector is concave toward the windward side of the evaporator. However, in the embodiment of the present invention, preferably, the opening of the arc-shaped deflector faces away from the windward side of the evaporator, that is, the arc-shaped deflector protrudes toward the evaporator The windward side of the evaporator; in this way, the wind speed distribution across the windward side of the evaporator is more uniform.
可选的，如图5所示，所述导流板为曲面形状，所述曲面包括至少两个弧面；具体导流板的曲面形状以能使穿过蒸发器迎风面的风速分布均匀，从而能达到改善蒸发器的换热效率为准。Optionally, as shown in FIG. 5, the deflector is in the shape of a curved surface, and the curved surface includes at least two arc surfaces; the specific curved shape of the deflector can make the wind speed distribution through the windward side of the evaporator uniform, Thereby, the heat exchange efficiency of the evaporator can be improved.
对于上述的导流板为弧面形状或曲面形状，本发明也适用于无开口，即导流板的弧面、曲面形成闭合的情况。例如导流板可以为椭圆形状，以能使穿过蒸发器迎风面的风速分布均匀，从而能达到改善蒸发器的换热效率即可。As for the arc-shaped or curved-surface shape of the above-mentioned deflector, the present invention is also applicable to the situation that there is no opening, that is, the arc and curved surfaces of the deflector are closed. For example, the deflector can be in the shape of an ellipse, so as to make the wind speed distribution through the windward side of the evaporator uniform, so as to improve the heat exchange efficiency of the evaporator.
需要说明的是，上述图2、图4、图5所示的导流板的形状同样可以应用于蒸发器以倾斜型或“V”型摆放的空调室内机，其摆放角度，以能使穿过蒸发器迎风面的风速分布均匀，从而能达到改善蒸发器的换热效率为准。It should be noted that the shapes of the deflectors shown in Figure 2, Figure 4, and Figure 5 above can also be applied to air-conditioning indoor units where the evaporator is placed in a tilted or "V" shape. Make the wind speed distribution through the windward side of the evaporator uniform, so as to improve the heat exchange efficiency of the evaporator.
上述任一种空调室内机中，所述导流板的个数为至少一个。根据空调室内机内部空间、蒸发器的摆放形状，以及能使穿过蒸发器迎风面的风速分布均匀，从而能达到改善蒸发器的换热效率的目的，导流板的数量根据实际情况设置。In any one of the air-conditioning indoor units above, the number of the deflector is at least one. According to the internal space of the indoor unit of the air conditioner, the placement shape of the evaporator, and the uniform distribution of the wind speed passing through the windward side of the evaporator, so as to achieve the purpose of improving the heat exchange efficiency of the evaporator, the number of deflectors is set according to the actual situation .
为了方便描述，在本发明实施例中，将进风口与所述蒸发器所形成空间以中间平面为界分为两部分，其中靠近进风口的那部分称为上半部分，远离进风口的那部分称为下半部分。For the convenience of description, in the embodiment of the present invention, the space formed by the air inlet and the evaporator is divided into two parts with the middle plane as the boundary, the part close to the air inlet is called the upper part, and the part far away from the air inlet part is called the lower half.
进一步地，参考图1、图2、图4、图5，所述蒸发器呈“A”型摆放，所述导流板对称置于所述进风口与所述蒸发器所形成空间的上半部分。这样，保证使蒸发器上部风速增大，避免蒸发器上下部风速同时增大。Further, referring to Fig. 1, Fig. 2, Fig. 4, and Fig. 5, the evaporator is arranged in an "A" shape, and the deflector is placed symmetrically on the space formed by the air inlet and the evaporator. half portion. In this way, the wind speed at the upper part of the evaporator is guaranteed to increase, and the wind speed at the upper and lower parts of the evaporator is prevented from increasing at the same time.
进一步地，参考图6，所述蒸发器呈“V”型摆放，所述导流板对称置于所述进风口与所述蒸发器所形成空间的下半部分。这样，在保证蒸发器上部风速增大的同时，避免下部风速过低而造成的蒸发器上下部风速仍不均匀的情况发生。Further, referring to FIG. 6 , the evaporator is placed in a "V" shape, and the deflector is placed symmetrically in the lower half of the space formed by the air inlet and the evaporator. In this way, while ensuring the increase of the wind speed at the upper part of the evaporator, it is avoided that the wind speed at the upper and lower parts of the evaporator is still uneven due to the low wind speed at the lower part.
对于所述的导流板，其具体的尺寸规格，以实际应用过程为准，在本发明实施例中不做限定。另外，对应导流板所使用的材料在本发明是实施例中也不做限定，以能使穿过蒸发器迎风面的风速分布均匀，从而能达到改善蒸发器的换热效率为准。As for the deflector, its specific dimensions are subject to the actual application process, and are not limited in the embodiment of the present invention. In addition, the materials used for the deflectors are not limited in the embodiments of the present invention, as long as the wind velocity distribution passing through the windward side of the evaporator can be uniform, so as to improve the heat exchange efficiency of the evaporator.
另一方面，本发明实施例提供一种空调，该空调包括空调室内机和空调室外机；其中空调室内机可以参考上述任一实施例中所描述的空调室内机，在此不加赘述。On the other hand, an embodiment of the present invention provides an air conditioner, the air conditioner includes an air conditioner indoor unit and an air conditioner outdoor unit; for the air conditioner indoor unit, reference may be made to the air conditioner indoor unit described in any of the above embodiments, and details are not described here.
上述提供的空调，可以是普通空调，也可以是精密空调，即有高精度控温要求的空调。The air conditioner provided above can be an ordinary air conditioner or a precision air conditioner, that is, an air conditioner that requires high-precision temperature control.
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以所述权利要求的保护范围为准。The above is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Anyone skilled in the art can easily think of changes or substitutions within the technical scope disclosed in the present invention. Should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the protection scope of the claims.
