机壳110形成立式空调室内机100内各组件的安装空间，其可以为向上延伸的圆柱。在机壳110内部限定出用于放置换热部120以及出风风机130的空腔。换热部120设置在机壳110内部，其底部与机壳110相连，并且沿机壳110高度方向延伸。换热部120在水平截面上的形状可以为弧形，在周向上与机壳110的侧壁形成供空气进入换热部120的进风区123，以使得空气可以进入至换热部120进行换热，而在相背于进风区123的一侧围成有用于放置出风风机130的风机放置区124。换热部120包括沿机壳110高度方向延伸的换热器121以及设置于换热器121顶部的固定架122。The cabinet 110 forms an installation space for each component in the vertical air conditioner indoor unit 100, and it may be a cylinder extending upward. A cavity for placing the heat exchange part 120 and the air outlet fan 130 is defined inside the cabinet 110. The heat exchange portion 120 is provided inside the cabinet 110, and the bottom thereof is connected to the cabinet 110 and extends in the height direction of the cabinet 110. The shape of the heat exchange portion 120 in a horizontal cross section may be an arc, and an air inlet area 123 for air to enter the heat exchange portion 120 is formed in the circumferential direction with the side wall of the cabinet 110 so that air can enter the heat exchange portion 120 for For heat exchange, a fan placement area 124 for placing the outlet fan 130 is enclosed on the side opposite to the air inlet area 123. The heat exchange part 120 includes a heat exchanger 121 extending in the height direction of the cabinet 110 and a fixing frame 122 provided on the top of the heat exchanger 121.
出风风机130为一个沿机壳高度方向布置的贯流风机，其具有从上至下为一整体的贯流风轮。出风风机130设置在机壳110内部，用于将进入机壳110内的空气引导至换热部120，经换热后排出至机壳110外部，以达到对室内温度进行调节的目的。出风风机130既可以将已经进入机壳110内部的空气引至换热部120，也可以从机壳110外部的空气吸入至机壳110内部。并且将空气引导至换热部120的方式可以为空气从出风风机130吹出至换热部120，也可以为通过出风风机130形成负压将空气吸入出风风机130，在进入出风风机130的过程中穿过换热部120进行换热。The outlet fan 130 is a cross-flow fan arranged along the height direction of the cabinet, and has a cross-flow wind wheel as a whole from top to bottom. The air outlet fan 130 is disposed inside the casing 110, and is used to guide the air entering the casing 110 to the heat exchange part 120, and to be discharged to the outside of the casing 110 after heat exchange, so as to adjust the indoor temperature. The air outlet fan 130 may guide the air that has entered the interior of the cabinet 110 to the heat exchange part 120, or may draw the air from the exterior of the cabinet 110 into the interior of the cabinet 110. And the way of guiding the air to the heat exchange part 120 may be that the air is blown out from the air outlet fan 130 to the heat exchange part 120, or the air may be drawn into the air outlet fan 130 by forming a negative pressure through the air outlet fan 130, before entering the air outlet fan During the process of 130, heat is exchanged through the heat exchange unit 120.
引风风机140至少包含一个，安装在机壳110内部，用于将机壳110外部的空气供向出风风机130，以提高出风风机130的风力。通过将机壳110外部的空气强制吸入至机壳110内部并供向出风风机130，不仅增加了进风 风量，使得立式空调室内机100的风量得到大幅度增加，而且可以提高进风风速，显著提升换热效率。At least one induced draft fan 140 is installed inside the casing 110 and is used to supply the air outside the casing 110 to the outlet fan 130 to increase the wind force of the outlet fan 130. By forcing the air outside the cabinet 110 into the interior of the cabinet 110 and supplying it to the outlet fan 130, not only increases the intake air volume, but also greatly increases the air volume of the vertical air conditioner indoor unit 100, and can increase the intake air speed , Significantly improve heat exchange efficiency.
在一些可选的实施例中，引风风机140可以为一个。引风风机140安装在机壳110内部，并且设置为可以向出风风机130供风。引风风机140将机壳110外部的空气吸入机壳110后，吹向出风风机130。出风风机130再次对空气做功，引导空气穿过换热部120进行换热，并且将换热后的空气排至室内。通过引风风机140与出风风机130的配合，增大进风风量和风速，使得通过换热部120的空气具有较强的扰动，从而增加换热效率。In some optional embodiments, there may be one induced draft fan 140. The induced draft fan 140 is installed inside the casing 110 and is configured to supply air to the outgoing fan 130. The induced draft fan 140 sucks the air outside the casing 110 into the casing 110 and then blows it toward the outlet fan 130. The air outlet fan 130 performs work on the air again, guides the air through the heat exchange section 120 for heat exchange, and discharges the heat exchanged air to the room. Through the cooperation of the induced draft fan 140 and the outflow fan 130, the intake air volume and wind speed are increased, so that the air passing through the heat exchange part 120 has strong disturbance, thereby increasing the heat exchange efficiency.
在另一些可选的实施例中，引风风机140可以为多个，例如两个。两个引风风机140可以同时开启，也可以单独开启。每个迎风风机均可以与出风风机130单独进行配合，以满足用户对不同风量的需求。两个引风风机140的出风方向设置为朝向不同方向，优选地，两个引风风机140的出风方向朝向换热部120不同的换热面。不仅可以避免当两个引风风机140同时开启时，相互之间的出风发生干扰，导致不必要的能量损失，而且可以使得吹向换热部120的空气可以更加均匀的覆盖换热部120，提高整体换热效率。In other optional embodiments, there may be a plurality of induced draft fans 140, for example, two. The two induced draft fans 140 can be turned on simultaneously or independently. Each upwind fan can be individually coordinated with the outflow fan 130 to meet user needs for different air volumes. The air outlet directions of the two induced draft fans 140 are set to face different directions. Preferably, the outflow directions of the two induced draft fans 140 face different heat exchange surfaces of the heat exchange part 120. Not only can it avoid interference between the two outflow fans 140 when they are turned on at the same time, resulting in unnecessary energy loss, but also can make the air blown to the heat exchange portion 120 more uniformly cover the heat exchange portion 120 To improve the overall heat exchange efficiency.

When there are two or more draught fans 140, a corresponding number of first air inlets 111 are also opened on the casing 110, and each draught fan 140 is provided corresponding to the corresponding first air inlet 111. Between the first air inlet and the air inlet of the air induction fan 140, an air guide device, such as an air guide plate, may be provided for the air induction fan 140 to better suck air from the room. A person skilled in the art can easily think that the induced draft fan 140 can also be installed on the cabinet 110 and directly opposed to the first air inlet 111. In addition, the first air inlet 111 may be provided on the side wall of the cabinet 110.
在一些可选的实施例中，引风风机140可以为离心风机，其排气口141与进风区123连通。引风风机140为径向排气，将其排气口141设置为与进 风区123连通，有助于将从引风风机140吸入的空气快速的供向进风区123，以供被出风风机130引导至换热部120。引风风机140还包括导风管142，导风管142与排气口141相接，并且伸入至进风区123。在排气口141设置伸入至进风区123的导风管142可以使得从引风风机140排出的空气更加准确的排入至进风区123。In some optional embodiments, the induced draft fan 140 may be a centrifugal fan, and its exhaust port 141 communicates with the intake area 123. The induced draft fan 140 is radial exhaust, and its exhaust port 141 is provided to communicate with the intake area 123, which helps to quickly supply the air drawn from the induced draft fan 140 to the intake area 123 for being discharged The fan 130 is guided to the heat exchange unit 120. The induced draft fan 140 further includes an air guide tube 142 that is connected to the exhaust port 141 and extends into the air intake area 123. The provision of the air guide tube 142 extending into the air inlet area 123 at the exhaust port 141 can make the air discharged from the air induction fan 140 be more accurately discharged into the air inlet area 123.
