When the indoor unit of the cabinet-type air conditioner is running, negative pressure will be generated in the penetrating channel due to the heat exchange air flow from the outlet of the heat exchange airflow. Under the action of negative pressure, the outdoor fresh air will flow into the indoor unit of the cabinet-type air conditioner through the fresh air duct and flow through the fresh air jet. The air duct flows out to mix with the heat exchange air flow flowing out through the first heat exchange air duct and the second heat exchange air duct to form a softer mixed air, which prevents the air outlet of the cabinet-type air conditioner indoor unit from being too cold or overheating, and , In the air supply process of the cabinet-type air conditioner indoor unit, outdoor fresh air is continuously introduced into the room, so the user's comfort experience can be improved in both the air outlet temperature and air freshness.
进一步地,柜式空调室内机还特别设有用于驱动室外新风通过新风管流向新风射流风道、并经射流风道送出的新风风机,也就是说,新风风机能够主动地将室外新风引入柜式空调室内机的送风路径中,相比于传统的利用负压被动引流的方式,本发明通过设置新风风机主动射流,射流风量大大提高,送风距离增加,提高了柜式空调室内机柔和送风的效果、增大了其整体送风量、扩大了其送风范围。Furthermore, the cabinet-type air conditioner indoor unit is also specially equipped with a fresh air fan for driving the outdoor fresh air to flow through the fresh air duct to the fresh air jet duct and sending it out through the jet duct. In other words, the fresh air fan can actively introduce outdoor fresh air into the cabinet. Compared with the traditional passive drainage method using negative pressure in the air supply path of the air conditioner indoor unit, the present invention provides a fresh air fan with active jet flow, which greatly increases the jet air volume and air supply distance, thereby improving the softness of the cabinet air conditioner indoor unit. The effect of air supply increases its overall air supply volume and expands its air supply range.
进一步地,本发明进一步将新风管的一端设置成与新风风机的气流入口密封地连接,并将新风管的另一端设置成可操作地沿新风管的径向伸缩,在柜式空调室内机安装之前,可将新风管缩回,以避免柜式空调室内机占用过多空间或与其他结构产生干涉,提高了柜式空调室内机搬运或运输的便利性;在柜式空调室内机安装时,还可以将新风管伸出,以便于其穿过墙壁与室外环境连通,提高了柜式空调室内机安装的便利性。Further, in the present invention, one end of the fresh air pipe is set to be hermetically connected to the airflow inlet of the fresh air fan, and the other end of the fresh air pipe is set to be operable to expand and contract along the radial direction of the fresh air pipe. Before the indoor unit is installed, the fresh air duct can be retracted to avoid the cabinet air conditioner indoor unit occupying too much space or interference with other structures, which improves the convenience of handling or transportation of the cabinet air conditioner indoor unit; in the cabinet air conditioner room When the unit is installed, the fresh air duct can also be extended so that it can pass through the wall and communicate with the outdoor environment, which improves the convenience of installing the cabinet air conditioner indoor unit.

The first heat exchange air duct 42 and the second heat exchange air duct 43, the first heat exchange air duct 42 and the second heat exchange air duct 43 both have heat exchange air outlets, and the first heat exchange air duct 42 and the second heat exchange air duct The heat exchange air duct 43 is equipped with a heat exchanger and a fan to promote the heat exchange airflow in the first heat exchange air duct 42 and the second heat exchange air duct 43 to be sent out through their own heat exchange airflow outlets through the fans. Specifically, two separate volute tongue assemblies 46 may be provided inside the casing 40 to jointly define a first heat exchange air duct 42 and a second heat exchange air duct 43 that are independent of each other with the casing 40. The air paths of the first heat exchange air duct 42 and the second heat exchange air duct 43 are independent of each other. The first heat exchange air duct 42 has a first heat exchange airflow outlet 421, and the first heat exchange air duct 42 is provided with a first The heat exchanger 51 and the first fan 61.

特别地,柜式空调室内机1还包括新风射流风道10和新风管70。新风射流风道10与第一换热风道42和第二换热风道43相互独立地设置在贯穿通道41的内部。也就是说,新风射流风道10与第一换热风道42和第二换热风道43相互独立,三个风道的风路相互独立,互不影响。In particular, the cabinet-type air conditioner indoor unit 1 further includes a fresh air jet duct 10 and a fresh air duct 70. The fresh air jet air duct 10 and the first heat exchange air duct 42 and the second heat exchange air duct 43 are independently arranged inside the through passage 41. In other words, the fresh air jet air duct 10 is independent of the first heat exchange air duct 42 and the second heat exchange air duct 43, and the air paths of the three air ducts are independent of each other and do not affect each other.
新风管70的一端直接或间接地与新风射流风道10相连通,另一端向机壳40外延伸,以便于延伸至室外环境,使得新风射流风道10通过新风管70与室外环境连通,从而允许室外新风经新风管70流向新风射流风道10、并经新风射流风道10流出后与经第一换热风道42和第二换热风道43送出的换热气流相混合。当柜式空调室内机1运行时,贯穿通道41内会因为换热气流出口送出换热气流而产生负压,在负压作用下,室外新风会经新风管70流入新风射流风道10并经新风射流风道10流出,从而与经第一换热风道42和第二换热风道43流出的换热气流相混合,形成比较柔和的混合风,避免了柜式空调室内机1出风过冷或过热,并且,在柜式空调室内机1的送风过程中源源不断地向室 内引入室外新风,因此可以在出风温度和空气新鲜度这两个方面同时提高用户的舒适性体验。One end of the fresh air duct 70 is directly or indirectly connected to the fresh air jet duct 10, and the other end extends to the outside of the casing 40, so as to extend to the outdoor environment, so that the fresh air jet duct 10 communicates with the outdoor environment through the fresh air duct 70 , Thereby allowing the outdoor fresh air to flow through the fresh air duct 70 to the fresh air jet duct 10, and after flowing out through the fresh air jet duct 10, it is mixed with the heat exchange air flow sent out through the first heat exchange duct 42 and the second heat exchange duct 43 . When the cabinet-type air conditioner indoor unit 1 is operating, negative pressure will be generated in the penetrating channel 41 due to the heat exchange air flow from the outlet of the heat exchange air flow. Under the action of the negative pressure, the outdoor fresh air will flow into the fresh air jet duct 10 through the fresh air duct 70. It flows out through the fresh air jet duct 10, and thus mixes with the heat exchange airflow flowing out through the first heat exchange duct 42 and the second heat exchange duct 43 to form a relatively soft mixed air, which avoids the cabinet-type air conditioner indoor unit 1. The wind is too cold or too hot, and the outdoor fresh air is continuously introduced into the room during the air supply process of the cabinet-type air conditioner indoor unit 1, so the user's comfort experience can be improved in both the outlet temperature and air freshness. .

The air outlet is connected with the fresh air jet duct 10 to controlly drive the outdoor fresh air to flow to the fresh air jet duct 10 through the fresh air fan 20 and send it out through the fresh air jet duct 10, so that the outdoor fresh air flowing out through the fresh air jet duct 10 It is mixed with the heat exchange air flow sent through the first heat exchange air passage 42 and the second heat exchange air passage 43. That is to say, the fresh air fan 20 can actively introduce outdoor fresh air into the fresh air jet duct 10 and encourage it to flow out through the fresh air jet duct 10.

The fan 20 actively jets, the jet air volume is greatly increased, the air supply distance is increased, the soft air supply effect of the cabinet-type air conditioner indoor unit 1 is improved, the overall air supply volume is increased, and the air supply range is enlarged.
在一些实施例中,新风管70的一端与新风风机20的气流入口21密封地连接,另一端设置成可操作地沿新风管70的径向伸缩。由此,在柜式空调室内机1安装之前,可将新风管70缩回,以避免柜式空调室内机1占用过多空间或与其他装置产生干涉,提高了柜式空调室内机1搬运或运输的便利性;在柜式空调室内机1安装时,还可以将新风管70伸出,以便于其穿过墙壁与室外环境连通,提高了柜式空调室内机1安装的便利性。In some embodiments, one end of the fresh air pipe 70 is hermetically connected with the air inlet 21 of the fresh air fan 20, and the other end is configured to be operatively telescopic in the radial direction of the fresh air pipe 70. Therefore, before the cabinet-type air conditioner indoor unit 1 is installed, the fresh air duct 70 can be retracted to prevent the cabinet-type air conditioner indoor unit 1 from occupying too much space or interference with other devices, thereby improving the handling of the cabinet-type air conditioner indoor unit 1. Or the convenience of transportation; when the cabinet-type air conditioner indoor unit 1 is installed, the fresh air duct 70 can also be extended so that it can pass through the wall and communicate with the outdoor environment, which improves the convenience of installation of the cabinet-type air conditioner indoor unit 1.
具体地,新风管70的另一端端口可设有进风格栅72,以避免室外环境中较大的杂物经进风管70进入柜式空调室内机1。新风管70可以包括多个内外嵌套设置的套管,每个套管均具有沿其径向渐缩的形状,多个套管的渐缩方向相同。在柜式空调室内机1安装之前,多个套管紧密地套设在一起,且多个套管尺寸较大的一端邻近设置。在柜式空调室内机1安装时,将多个套管拉开,使得多个套管两两相接。新风管70还可以为内部中空的万节管、塑料软管或者其他合适的管体。Specifically, an inlet grill 72 may be provided at the other end of the fresh air duct 70 to prevent large debris in the outdoor environment from entering the cabinet-type air conditioner indoor unit 1 through the air inlet duct 70. The fresh air duct 70 may include a plurality of sleeves nested inside and outside, each sleeve having a shape that is tapered along its radial direction, and the tapering directions of the plurality of sleeves are the same. Before the cabinet-type air conditioner indoor unit 1 is installed, a plurality of sleeves are tightly sleeved together, and an end of the plurality of sleeves with a larger size is adjacently arranged. When the cabinet-type air conditioner indoor unit 1 is installed, the multiple sleeves are pulled apart so that the multiple sleeves are connected in pairs. The fresh air pipe 70 may also be a hollow tube, plastic hose or other suitable pipe body.
在一些实施例中,柜式空调室内机1还包括净化模块71,用于对由新风管70流向新风射流风道10的室外新风进行净化。净化模块71可以设置在新风管71内,例如设置在新风管70与新风风机20邻接的位置处,净化模块71还可以设置在新风风机20与新风射流风道10之间的气流流动路径上。In some embodiments, the cabinet-type air conditioner indoor unit 1 further includes a purification module 71 for purifying the outdoor fresh air flowing from the fresh air duct 70 to the fresh air jet duct 10. The purification module 71 may be arranged in the fresh air duct 71, for example, at a position where the fresh air duct 70 is adjacent to the fresh air fan 20, and the purification module 71 may also be arranged in the air flow path between the fresh air fan 20 and the fresh air jet duct 10. superior.
具体地,净化模块71可以包括过滤单元和吸附单元,过滤单元用于过滤室外新风中较大的杂质,吸附单元用于对室外进风中的有害物质进行去除。另外,净化模块71还可以包括其他能够对空气具有净化功能的单元。Specifically, the purification module 71 may include a filter unit and an adsorption unit. The filter unit is used to filter relatively large impurities in the outdoor fresh air, and the adsorption unit is used to remove harmful substances in the outdoor air intake. In addition, the purification module 71 may also include other units capable of purifying air.
在一些实施例中,新风射流风道10的风道壁与贯穿通道41的侧壁之间限定有至少一个引风通道44。当第一换热风道42和第二换热风道43内的风机运转时和/或当新风风机20运转时,引风通道44的前部会产生一定的负压。在该负压作用下,柜式空调室内机1所处空间内的空气流入引风通道44,并经引风通道44的前部开口送出,与经新风射流风道10流出的未经换热的室外新风、以及经第一换热风道42和第二换热风道43送出的换热气流相混合。由此,增大了柜式空调室内机1引入的未经换热的空气总量,提高了其整体送风量。In some embodiments, at least one air induction channel 44 is defined between the air channel wall of the fresh air jet air channel 10 and the side wall of the through channel 41. When the fans in the first heat exchange air duct 42 and the second heat exchange air duct 43 are in operation and/or when the fresh air fan 20 is in operation, a certain negative pressure will be generated at the front of the induction duct 44. Under the action of this negative pressure, the air in the space where the cabinet-type air conditioner indoor unit 1 is located flows into the air induction channel 44, and is sent out through the front opening of the air induction channel 44, and exchanges with the unheated air flowing out through the fresh air jet duct 10 The outdoor fresh air and the heat exchange air flow sent through the first heat exchange air duct 42 and the second heat exchange air duct 43 are mixed. As a result, the total amount of unheated air introduced by the cabinet-type air conditioner indoor unit 1 is increased, and the overall air supply volume thereof is increased.
进一步地,参见图5,新风射流风道10可固定地设置在贯穿通道41内。也就是说,引风通道44的过流面积是不可调的,柜式空调室内机1每次启动运行时都会通过引风通道44引入大致相同量的室内自然空气。Further, referring to FIG. 5, the fresh air jet air duct 10 may be fixedly arranged in the through channel 41. In other words, the flow area of the induced air passage 44 is not adjustable, and the cabinet-type air conditioner indoor unit 1 will introduce approximately the same amount of indoor natural air through the induced air passage 44 every time the cabinet-type air conditioner indoor unit 1 starts operation.
图6和图7是根据本发明另一个实施例的柜式空调室内机处于不同状态下的沿水平剖切面截取的示意性剖视图。在另一些实施例中,新风射流风道10可设置成受控地或可操作地在贯穿通道41内移动,以开闭至少一个引风通道44和/或调节至少一个引风通道44的过流面积。图6所示状态为引风通道44打开的状态,图7所示状态为引风通道44关闭的状态。也就是说,通过移动新风射流风道10可以调节新风射流风道10的风道壁与贯穿通道41的侧壁之间的距离,从而打开、关闭引风通道44或者调节引风通道44的大小,省去了用于专门控制引风通道44开闭或调节引风通道44大小的机构,简化了柜式空调室内机1的结构。6 and 7 are schematic cross-sectional views taken along a horizontal cross-sectional plane of the cabinet-type air conditioner indoor unit in different states according to another embodiment of the present invention. In other embodiments, the fresh air jet duct 10 may be configured to move in the through passage 41 in a controlled or operative manner to open and close at least one air induction channel 44 and/or to adjust the passage of at least one air induction channel 44. Flow area. The state shown in FIG. 6 is a state where the air induction channel 44 is open, and the state shown in FIG. 7 is a state where the air induction channel 44 is closed. That is to say, by moving the fresh air jet duct 10, the distance between the air duct wall of the fresh air jet duct 10 and the side wall of the penetrating channel 41 can be adjusted, thereby opening and closing the air induction channel 44 or adjusting the size of the air induction channel 44 Therefore, a mechanism for specifically controlling the opening and closing of the air induction channel 44 or adjusting the size of the air induction channel 44 is omitted, and the structure of the cabinet-type air conditioner indoor unit 1 is simplified.
在一些实施例中,第一换热风道42和第二换热风道43的换热气流出口均朝向机壳40的前侧, 新风射流风道10的前侧开设有新风出风口12。也就是说,三个风道都朝向机壳40的前侧送风,以便于使得从两个换热风道流出的换热气流与从新风射流风道10流出的未经换热的室外新风在机壳40的前侧或前部进行混合。并且,将新风射流风道10设置在处于两个换热风道之间的贯穿通道41内,可使得新风射流风道10处于两个换热风道之间,从而使新风射流风道10送出的室外新风处于两股换热气流之间,进而使得室外新风与换热气流之间的混合更加均匀。需要说明的是,本发明所称的机壳40的前侧可包括机壳40的正前侧、也可以包括机壳40的斜前侧,只要换热气流出口的朝向具有朝前的方向分量以能够朝向机壳40的前侧送风即可。In some embodiments, the heat exchange air outlets of the first heat exchange air duct 42 and the second heat exchange air duct 43 both face the front side of the casing 40, and the fresh air jet duct 10 is provided with a fresh air outlet 12 on the front side. In other words, the three air ducts all send air toward the front side of the casing 40, so that the heat exchange air flow from the two heat exchange air ducts and the unheated outdoor fresh air flowing from the fresh air jet duct 10 The mixing is performed on the front side or front of the cabinet 40. In addition, the fresh air jet air duct 10 is arranged in the through channel 41 between the two heat exchange air ducts, so that the fresh air jet air duct 10 is between the two heat exchange air ducts, so that the fresh air jet air duct 10 is sent out The outdoor fresh air is located between the two heat exchange airflows, which makes the mixing between the outdoor fresh air and the heat exchange airflow more even. It should be noted that the front side of the casing 40 referred to in the present invention may include the front side of the casing 40 or the oblique front side of the casing 40, as long as the direction of the heat exchange airflow outlet has a forward direction component. What is necessary is just to be able to blow air toward the front side of the cabinet 40.
进一步地,新风射流风道10的两个横向风道壁10f分别与贯穿通道41的两个横向侧壁41a间隔设置,以在新风射流风道10的两个横向外侧分别形成一个引风通道44,以从横向两侧同时引入室内自然空气,便于室内自然空气与换热气流混合的更加均匀。本领域技术人员应理解,本发明所称的自然空气意指未经换热的空气。Further, the two lateral air duct walls 10f of the fresh air jet air duct 10 are respectively spaced apart from the two lateral side walls 41a of the through passage 41, so as to form an air guide duct 44 on the two lateral outer sides of the fresh air jet air duct 10 respectively. , To introduce indoor natural air from both lateral sides at the same time, so that the indoor natural air and the heat exchange airflow can be mixed more evenly. Those skilled in the art should understand that the natural air referred to in the present invention means air without heat exchange.
在一些实施例中,新风射流风道10设置于贯穿通道41的后部区段411,且新风射流风道10与贯穿通道后部区段411的形状相适配,以使得新风射流风道10与贯穿通道41之间的结构布局更加紧凑以减小柜式空调室内机1的体积。贯穿通道41的后部区段411以及新风射流风道10的横截面均由后向前地渐缩,以便于在新风射流风道10内形成由后向前渐缩的导流腔11,使得室外新风快速地朝前流出。In some embodiments, the fresh air jet duct 10 is arranged in the rear section 411 of the through passage 41, and the fresh air jet duct 10 matches the shape of the rear section 411 of the through duct, so that the fresh air jet duct 10 The structural layout between and the through passage 41 is more compact to reduce the volume of the cabinet type air conditioner indoor unit 1. The cross section of the rear section 411 through the passage 41 and the cross section of the fresh air jet duct 10 are tapered from back to front, so as to form a diversion cavity 11 that is tapered from back to front in the fresh air jet duct 10, so that The outdoor fresh air flows forward quickly.
在一些实施例中,例如图6和图7所示实施例,新风射流风道10设置成受控地或可操作地沿前后方向移动,以在其向前移动至使其两个横向风道壁10f分别与贯穿通道后部区段411的两个侧壁41a相抵接时关闭两个引风通道44、在其向后移动至使其两个横向风道壁10f分别与贯穿通道后部区段411的两个侧壁41a之间存在间隙时打开两个引风通道44。由于贯穿通道41的后部区段411以及新风射流风道10均由后向前地渐缩,因此,随着新风射流风道10的向后移动,其两个横向风道壁10f与贯穿通道后部区段411的两个侧壁41a之间的距离越来越大,即引风通道44的过流面积越来越大。反之,随着新风射流风道10的向前移动,其两个横向风道壁10f与贯穿通道后部区段411的两个侧壁41a之间的距离越来越小,即引风通道44的过流面积越来越小。当新风射流风道10向前移动至预定位置时,其两个横向风道壁10f与贯穿通道后部区段411的两个侧壁41a相抵接,此时引风通道44被完全关闭。如此,可通过新风射流风道10的前后移动来调节两个引风通道44的过流面积大小,从而调节引风通道44引入的自然空气的量。In some embodiments, such as the embodiment shown in FIGS. 6 and 7, the fresh air jet duct 10 is configured to move in a forward and backward direction in a controlled or operative manner so as to move forward to make its two transverse ducts When the wall 10f abuts against the two side walls 41a of the rear section 411 of the penetrating channel, the two air-inducing channels 44 are closed, and the two air duct walls 10f are moved backward so that the two transverse air channel walls 10f are respectively connected to the rear area of the penetrating channel. When there is a gap between the two side walls 41a of the segment 411, two air induction channels 44 are opened. Since the rear section 411 of the through passage 41 and the fresh air jet duct 10 are tapered from back to front, as the fresh air jet duct 10 moves backward, its two transverse air duct walls 10f and the through duct 10 The distance between the two side walls 41a of the rear section 411 becomes larger and larger, that is, the flow area of the air induction channel 44 becomes larger and larger. Conversely, as the fresh air jet air duct 10 moves forward, the distance between its two transverse air duct walls 10f and the two side walls 41a that penetrate the rear section 411 of the duct becomes smaller and smaller, that is, the air duct 44 The flow area is getting smaller and smaller. When the fresh air jet air duct 10 moves forward to a predetermined position, its two transverse air duct walls 10f abut the two side walls 41a penetrating the rear section 411 of the duct, and the air induction duct 44 is completely closed at this time. In this way, the flow area of the two air induction channels 44 can be adjusted by moving the fresh air jet air channel 10 back and forth, so as to adjust the amount of natural air introduced by the air induction channel 44.
在一些实施例中,新风射流风道10的横截面呈由后向前渐缩的梯形。当新风射流风道10可动地设置在贯穿通道41内时,在两个引风通道44处于关闭状态时,即新风射流风道10的两个横向风道壁10f与贯穿通道后部区段411的两个侧壁41a相抵接时,新风射流风道10的后向表面10e与机壳40的后向表面相平齐。柜式空调室内机1处于停机状态时,可控制引风通道44处于关闭状态,以避免灰尘杂物进入机壳40内。由此,可提高柜式空调室内机1外形的完整程度和美观程度。当新风射流风道10固定地设置在贯穿通道41内时,新风射流风道10的后向表面10e与机壳40的后向表面相平齐。In some embodiments, the cross section of the fresh air jet duct 10 is a trapezoid that tapers from back to front. When the fresh air jet duct 10 is movably arranged in the through passage 41, when the two induction ducts 44 are in a closed state, that is, the two transverse air duct walls 10f of the fresh air jet duct 10 and the rear section of the through passage When the two side walls 41a of the 411 abut, the rearward surface 10e of the fresh air jet duct 10 is flush with the rearward surface of the casing 40. When the cabinet-type air conditioner indoor unit 1 is in a shutdown state, the induced air passage 44 can be controlled to be in a closed state to prevent dust and debris from entering the cabinet 40. As a result, the completeness and appearance of the cabinet-type air conditioner indoor unit 1 can be improved. When the fresh air jet air duct 10 is fixedly arranged in the through passage 41, the rearward surface 10e of the fresh air jet duct 10 is flush with the rearward surface of the casing 40.
进一步地,新风射流风道10的横截面可以为等腰梯形。Further, the cross section of the fresh air jet duct 10 may be an isosceles trapezoid.
在一些实施例中,机壳40上还开设有第一进风口451和第二进风口452,第一换热风道42和第二换热风道43分别与第一进风口451和第二进风口452连通,以通过第一风机61促使柜式空调室内机1外部的空气经第一进风口451流入第一换热风道42,通过第二风机62使柜式空调室内机1外部的空气经第二进风口452流入第二换热风道43。In some embodiments, the casing 40 is further provided with a first air inlet 451 and a second air inlet 452, and the first heat exchange air duct 42 and the second heat exchange air duct 43 are connected to the first air inlet 451 and the second air inlet respectively. The air inlet 452 is connected, so that the air outside the cabinet-type air conditioner indoor unit 1 is encouraged to flow into the first heat exchange air duct 42 through the first air inlet 451 through the first fan 61, and the air outside the cabinet-type air conditioner indoor unit 1 The air flows into the second heat exchange air duct 43 through the second air inlet 452.
进一步地,贯穿通道41可形成在机壳40的中部,第一进风口451和第二进风口452可分别位于机壳40的横向两侧,以避免第一换热风道42和第二换热风道43的进风产生干扰。第一换热风道42和第二换热风道43内的换热器、以及第一换热风道42和第二换热风道43内的风机均关于机壳40在 横向上的竖直平分面m对称设置,也就是说,第一换热器51和第二换热器52左右对称设置,第一风机61和第二风机62左右对称设置。两个引风通道44也可以关于机壳40在横向上的竖直平分面m对称设置。Further, the through channel 41 may be formed in the middle of the casing 40, and the first air inlet 451 and the second air inlet 452 may be respectively located on both lateral sides of the casing 40 to avoid the first heat exchange air duct 42 and the second heat exchange duct. The inlet air of the hot air duct 43 interferes. The heat exchangers in the first heat exchange air duct 42 and the second heat exchange air duct 43, and the fans in the first heat exchange air duct 42 and the second heat exchange air duct 43 are all vertical to the casing 40 in the transverse direction. The straight planes m are symmetrically arranged, that is, the first heat exchanger 51 and the second heat exchanger 52 are arranged symmetrically, and the first fan 61 and the second fan 62 are arranged symmetrically. The two induced air passages 44 may also be symmetrically arranged with respect to the vertical bisecting plane m of the casing 40 in the transverse direction.
在一些实施例中,第一换热风道42和第二换热风道43内的风机均为转动轴沿竖直方向延伸的贯流风机。也即是,第一风机61和第二风机62均为竖向延伸的贯流风机,相应地,第一进风口451、第二进风口452、第一换热气流出口421、第二换热气流出口431、新风出风口12以及送风口453均为沿竖向延伸的长条形风口。新风射流风道10为沿竖向延伸的长形风道。由此,可增加柜式空调室内机1在竖直方向上的出风高度,扩大其送风范围。第一换热器51和第二换热器52分别为设置在第一风机61和第二风机62横向外侧的V形或弧形换热器。In some embodiments, the fans in the first heat exchange air duct 42 and the second heat exchange air duct 43 are cross-flow fans with a rotating shaft extending in a vertical direction. That is, both the first fan 61 and the second fan 62 are cross-flow fans extending vertically.

The first heat exchanger 51 and the second heat exchanger 52 are V-shaped or arc-shaped heat exchangers arranged laterally outside the first fan 61 and the second fan 62, respectively.
在一些实施例中,新风风机20为设置于新风射流风道10下方的离心风机,以受控地驱动室外新风经新风管70水平地流入离心风机、并由下往上地流进新风射流风道10。In some embodiments, the fresh air fan 20 is a centrifugal fan disposed under the fresh air jet duct 10 to controlly drive the outdoor fresh air to flow into the centrifugal fan horizontally through the fresh air pipe 70, and flow into the fresh air jet from bottom to top. Air duct 10.
本发明的新风风机20选择为离心风机,且使其处于新风射流风道10的下方,以尽可能地减小新风风机20和新风射流风道10形成的组件在横向上的尺寸,增加其在竖直方向上的高度,由此,可充分利用柜式空调室内机1高度方向上较高的优势,使得新风射流风道10、新风风机20与柜式空调室内机的机壳40等结构之间的布局更加紧凑,避免采用贯流式的新风风机,并将其设置在新风射流风道内造成新风射流风道在水平方向上的尺寸过大进而导致柜式空调室内机的体积过大、占用室内空间过大的问题。同时,离心风机的气流入口面积较小,便于与新风管70密封地连接,减小了新风管70的尺寸和体积。The fresh air fan 20 of the present invention is selected as a centrifugal fan, and is placed below the fresh air jet duct 10, so as to reduce the size of the components formed by the fresh air fan 20 and the fresh air jet duct 10 in the lateral direction as much as possible, and increase its The height in the vertical direction, thus, the advantage of the height direction of the cabinet-type air conditioner indoor unit 1 can be fully utilized, so that the fresh air jet duct 10, the fresh air fan 20 and the cabinet 40 of the cabinet-type air conditioner indoor unit can be integrated The layout of the room is more compact, avoiding the use of cross-flow fresh air fans, and setting them in the fresh air jet ducts, causing the fresh air jet ducts to be too large in the horizontal direction, which leads to the excessive volume and occupation of the cabinet-type air conditioner indoor unit. The problem of excessive indoor space. At the same time, the air inlet area of the centrifugal fan is small, which is convenient for sealingly connecting with the fresh air pipe 70, which reduces the size and volume of the fresh air pipe 70.
在一些实施例中,当新风射流风道10可移动时,新风风机20可固定地设置在新风射流风道10的下方,新风射流风道10配置成受控地或可操作地相对于新风风机20移动。也就是说,新风风机20是不动的,新风射流风道10可以相对于新风风机20移动。此时,新风射流风道10与新风风机20之间可通过能够产生可恢复弹性形变的软管连接,软管的设置既可以允许新风射流风道10与新风风机20之间产生相对位移,又能够确保新风射流风道10与新风风机20之间密封性较好的流体连通关系。在这些实施例中,柜式空调室内机1还包括用于驱动新风射流风道10移动的驱动装置,该驱动装置可以为现有任何可行的驱动装置,这里不再赘述。In some embodiments, when the fresh air jet duct 10 is movable, the fresh air fan 20 may be fixedly arranged below the fresh air jet duct 10, and the fresh air jet duct 10 is configured to be controlled or operatively relative to the fresh air fan 20 moves. In other words, the fresh air fan 20 is not moving, and the fresh air jet duct 10 can move relative to the fresh air fan 20. At this time, the fresh air jet duct 10 and the fresh air fan 20 can be connected by a hose capable of generating recoverable elastic deformation. The arrangement of the hose can allow relative displacement between the fresh air jet duct 10 and the fresh air fan 20, and It can ensure a fluid communication relationship with good sealing performance between the fresh air jet duct 10 and the fresh air fan 20. In these embodiments, the cabinet-type air conditioner indoor unit 1 further includes a driving device for driving the fresh air jet duct 10 to move. The driving device may be any available driving device, which will not be repeated here.
在另一些实施例中,当新风射流风道10可移动时,新风风机20也可以与新风射流风道10直接或间接地固定相连,新风射流风道10受控地或可操作地与新风风机20一起移动。也就是说,新风风机20与新风射流风道10不能够产生相对位移,但是二者可以一起移动。这种方式对新风射流风道10与新风风机20之间的连接方式没有特别要求,只要能够确保二者密封性较好的流体连通关系即可。在这些实施例中,柜式空调室内机1还包括用于驱动新风射流风道10和新风风机20同步移动的驱动装置,该驱动装置可以为现有任何可行的驱动装置,这里不再赘述。In other embodiments, when the fresh air jet duct 10 is movable, the fresh air fan 20 can also be directly or indirectly fixedly connected with the fresh air jet duct 10, and the fresh air jet duct 10 is controlled or operably connected to the fresh air fan. 20 move together. In other words, the fresh air fan 20 and the fresh air jet duct 10 cannot produce relative displacement, but they can move together. This method does not have special requirements for the connection between the fresh air jet duct 10 and the fresh air fan 20, as long as the fluid communication relationship between the two can be ensured with better sealing. In these embodiments, the cabinet-type air conditioner indoor unit 1 further includes a driving device for driving the fresh air jet duct 10 and the fresh air fan 20 to move synchronously. The driving device may be any existing feasible driving device, which will not be repeated here.
柜式空调室内机的送风口453通常为沿竖向延伸的条形送风口,为此,第一换热风道42和第二换热风道43的换热气流出口以及开设在新风射流风道10前侧的新风出风口12均为沿竖向延伸的条形风口,以增加柜式空调室内机1在竖直方向上的出风高度,扩大其送风范围。The air supply outlet 453 of the indoor unit of the cabinet type air conditioner is usually a strip-shaped air supply outlet extending in the vertical direction. The fresh air outlets 12 on the front side of the duct 10 are all strip-shaped air outlets extending in the vertical direction to increase the air outlet height of the cabinet-type air conditioner indoor unit 1 in the vertical direction and expand its air supply range.
然而,新风风机20位于新风射流风道10的下方,气流从下而上地流入出风风道20,与新风出风口12的出风方向垂直,因此如何确保新风出风口12送出较高流速的气流、以及如何实现新风出风口12在竖直方向上的均匀出风是本发明进一步实施例的设计难点和设计重点。However, the fresh air fan 20 is located below the fresh air jet duct 10, and the air flows into the air outlet duct 20 from bottom to top, and is perpendicular to the direction of the fresh air outlet 12, so how to ensure that the fresh air outlet 12 delivers a higher flow rate Airflow and how to achieve uniform air discharge from the fresh air outlet 12 in the vertical direction are the design difficulties and design focus of further embodiments of the present invention.
图8是根据本发明一个实施例的新风射流风道沿前后方向延伸的竖向剖切面截取的示意性结构剖视图,图9是图8中部分C的示意性放大图,图10是根据本发明一个实施例的新风射流风道沿水平剖切面截取的示意性剖视图。参见图8至图10,在一些实施例中,新风射流风道10内限定有竖向延伸的导流腔11,进入新风射流风道10内的气流经导流腔11导流后从新风射流风道10的新风出风口12流出。新风射流风道10的内部对称地设有两个竖向延伸的弧形导流板13,两个弧形导流板13 由后向前地朝相互靠近的方向凸出弯曲,以使得导流腔11邻近条形新风出风口12的前部形成渐缩的弧形收口部111。也就是说,弧形收口部111由后向前地渐缩,且大致呈由后向前的漏斗状。这种形状的导流板形成的渐缩弧形收口部可尽可能地降低气流流动阻力、提高流向新风出风口12的气流流速,从而提高了射流装置1的出风速度、延长了其送风距离。8 is a schematic structural cross-sectional view of a vertical section of the fresh air jet duct extending in the front-to-rear direction according to an embodiment of the present invention, FIG. 9 is a schematic enlarged view of part C in FIG. 8, and FIG. 10 is according to the present invention A schematic cross-sectional view of the fresh air jet duct of an embodiment taken along a horizontal cross-sectional plane. Referring to Figures 8 to 10, in some embodiments, the fresh air jet duct 10 defines a vertically extending diversion cavity 11, and the airflow entering the fresh air jet duct 10 flows through the diversion cavity 11 from the fresh air jet The fresh air outlet 12 of the air duct 10 flows out. The fresh air jet duct 10 is symmetrically provided with two arc-shaped deflectors 13 extending vertically, and the two arc-shaped deflectors 13 protrude and bend toward each other from back to front, so as to divert the air. The cavity 11 is adjacent to the front of the strip-shaped fresh air outlet 12 to form a tapered arc-shaped constriction 111. In other words, the arc-shaped constricted portion 111 tapers from back to front, and is generally in the shape of a funnel from back to front. The tapered arc-shaped constriction formed by the baffle of this shape can reduce the air flow resistance as much as possible and increase the air flow velocity to the fresh air outlet 12, thereby increasing the air outlet speed of the jet device 1 and extending its air supply. distance.
在一些实施例中,新风射流风道10的横截面呈梯形,该梯形的上底位于条形新风出风口12所在的前侧,该梯形的下底位于背离条形新风出风口12的后侧。两个弧形导流板13的后端分别由新风射流风道10对应于梯形两个腰部的两个侧板向前弯曲延伸。具体地,新风射流风道10具有前侧板10a、后侧板10b和两个横向侧板10c。后侧板10b的外侧表面形成新风射流风道10的后向表面10e,横向侧板10c的外侧表面形成新风射流风道10的横向风道壁10f。新风出风口12开设在前侧板10a上,前侧板10a的横截面为梯形的上底,后侧板10b的横截面为梯形的下底,两个横向侧板10c的横截面为梯形的两个腰。两个弧形导流板13分别由两个横向侧板10c的内表面向前弯曲延伸。也就是说,两个弧形导流板13的后端并没有延伸至新风射流风道10的最后侧。由此形成的导流腔11包括处于前部的弧形收口部111和处于后部的梯形容腔112两部分,梯形容腔112与弧形收口部111的分界线如图10中的点划线所示。In some embodiments, the cross section of the fresh air jet duct 10 is trapezoidal, the upper bottom of the trapezoid is located on the front side where the strip-shaped fresh air outlet 12 is located, and the bottom bottom of the trapezoid is located on the back side away from the strip-shaped fresh air outlet 12 . The rear ends of the two arc-shaped baffles 13 are respectively bent and extended forward by the two side plates of the fresh air jet duct 10 corresponding to the two waists of the trapezoid. Specifically, the fresh air jet duct 10 has a front side plate 10a, a rear side plate 10b, and two lateral side plates 10c. The outer surface of the rear side plate 10b forms the rear surface 10e of the fresh air jet duct 10, and the outer surface of the lateral side plate 10c forms the transverse air duct wall 10f of the fresh air jet duct 10. The fresh air outlet 12 is opened on the front side panel 10a, the cross section of the front side panel 10a is a trapezoidal upper bottom, the cross section of the rear side panel 10b is a trapezoidal lower bottom, and the cross section of the two transverse side panels 10c is trapezoidal. Two waists. The two arc-shaped baffles 13 are respectively curved and extended forward from the inner surfaces of the two lateral side plates 10c. In other words, the rear ends of the two arc-shaped baffles 13 do not extend to the rearmost side of the fresh air jet duct 10. The diversion cavity 11 thus formed includes two parts, an arc-shaped constriction 111 at the front and a ladder-like cavity 112 at the rear. The boundary line between the ladder-like cavity 112 and the arc-shaped constriction 111 is shown as a dotted line in Fig. 10 As shown in the line.
梯形容腔112不但具有由后向前地渐缩的形状以便于气流加速流向弧形收口部111,而且,梯形容腔112的后侧还具有较大的面积以供进入新风射流风道10内的气流经梯形容腔112的后侧从下往上流动,减小了气流的流动阻力,便于在新风出风口12处形成较为均匀的送风。The ladder-like cavity 112 not only has a shape that is tapered from back to front to facilitate the acceleration of the air flow to the arc-shaped constriction 111, and the back side of the ladder-like cavity 112 also has a larger area for entering the fresh air jet duct 10 The air flows from bottom to top through the rear side of the ladder cavity 112, which reduces the flow resistance of the air flow and facilitates the formation of a more uniform air supply at the fresh air outlet 12.
在一些实施例中,弧形收口部111向前延伸至条形新风出风口12,且弧形收口部111的最前端在横向上的尺寸与新风出风口12在横向上的尺寸一致。也就是说,弧形收口部111的最前端与新风出风口12无缝对接,从而可避免新风出风口12附近产生紊流现象。In some embodiments, the arc-shaped narrowing portion 111 extends forward to the strip-shaped fresh air outlet 12, and the lateral dimension of the foremost end of the arc-shaped narrowing portion 111 is the same as the lateral dimension of the fresh air outlet 12. In other words, the foremost end of the arc-shaped constricted portion 111 is seamlessly butted with the fresh air outlet 12, so that turbulence near the fresh air outlet 12 can be avoided.
在一些实施例中,导流腔11的横截面在由后向前的方向上呈渐缩的形状。具体地,导流腔11的横截面在前后方向上可呈规则的渐缩形状,也可以呈不规则的渐缩形状。例如,图10所示的导流腔11具有由后向前排列的梯形容腔112和弧形收口部111,并且,梯形容腔112和弧形收口部111均由后向前地渐缩,由此形成的导流腔11呈由后向前不规则的渐缩形状。In some embodiments, the cross section of the diversion cavity 11 has a tapered shape in a direction from back to front. Specifically, the cross section of the diversion cavity 11 may have a regular tapered shape in the front-to-rear direction, or may have an irregular tapered shape. For example, the diversion cavity 11 shown in FIG. 10 has a ladder-like cavity 112 and an arc-shaped constriction 111 arranged from back to front, and both the ladder-like cavity 112 and the arc-shaped constriction 111 are tapered from back to front. The diversion cavity 11 thus formed has an irregularly tapered shape from back to front.
进一步地,导流腔11的最后端在横向上的宽度W 4为新风出风口12在横向上的宽度W 6的5~10倍。由于导流腔11由后向前渐缩,弧形收口部111与新风出风口12无缝对接,因此导流腔11最后端的宽度为其最大宽度,新风出风口12的宽度为导流腔11的最小宽度。也即是,导流腔11的最大宽度为其最小宽度的5~10倍。例如,导流腔11的最大宽度可以为其最小宽度的5倍、6倍、7倍、8倍、9倍或10倍。由此,一方面可确保导流腔11后部具有能够使得进入新风射流风道10内的大部分气流向上流过的面积,另一方面,还使得新风出风口12的宽度足够小,使其整体呈竖向延伸的狭缝状新风出风口12以使得气流由后向前流动时获得足够大的加速,从而获得较大的出风速度和送风距离。更为重要的是,可使得新风出风口12在竖直方向上均匀出风。导流腔11的最大宽度和最小宽度的上述比例设计是平衡考虑多方面技术问题后所获得的结果,在上述各个方面都达到了较佳的技术效果。反之,如果导流腔11最后端的宽度相比于新风出风口12的宽度过大,会导致导流腔11后部的面积过大,气流流经导流腔11后部时距新风出风口12距离较远,此时大部分气流会直接通过导流腔11的后部向上流动,流向新风出风口12的气流量非常少,这就导致新风出风口12顶部的出风量较大、新风出风口12底部和中部的出风量非常小,新风出风口12的出风非常不均衡。如果导流腔11最后端的宽度与新风出风口12的宽度倍数较小,二者之间的宽度差别较小,气流由后向前流动时获得的加速效果不明显,新风出风口12的出风速度和送风距离都比较小。 Further, the width W 4 of the rearmost end of the diversion cavity 11 in the lateral direction is 5-10 times the width W 6 of the fresh air outlet 12 in the lateral direction. Since the diversion cavity 11 is tapered from back to front, and the arc-shaped closing portion 111 is seamlessly butted with the fresh air outlet 12, the width of the rear end of the diversion cavity 11 is the maximum width, and the width of the fresh air outlet 12 is the diversion cavity 11. The minimum width. That is, the maximum width of the diversion cavity 11 is 5-10 times the minimum width. For example, the maximum width of the diversion cavity 11 may be 5 times, 6 times, 7 times, 8 times, 9 times or 10 times of its minimum width. As a result, on the one hand, it can be ensured that the rear of the diversion cavity 11 has an area capable of allowing most of the airflow entering the fresh air jet duct 10 to flow upward, and on the other hand, the width of the fresh air outlet 12 is sufficiently small to make it The slit-shaped fresh air outlet 12 extending vertically as a whole allows the airflow to obtain a sufficiently large acceleration when flowing from back to front, so as to obtain a larger air outlet speed and air supply distance. More importantly, the fresh air outlet 12 can be made to emit air evenly in the vertical direction. The above-mentioned proportional design of the maximum width and the minimum width of the diversion cavity 11 is a result obtained after a balanced consideration of various technical problems, and a better technical effect is achieved in all the above aspects. Conversely, if the width of the rear end of the diversion cavity 11 is too large compared to the width of the fresh air outlet 12, the area of the rear of the diversion cavity 11 will be too large. The distance is far. At this time, most of the air flow will directly flow upwards through the rear of the diversion cavity 11, and the air flow to the fresh air outlet 12 is very small, which leads to a large amount of air at the top of the fresh air outlet 12 and the fresh air outlet 12 The air output at the bottom and the middle is very small, and the air output from the fresh air outlet 12 is very uneven. If the width of the rear end of the diversion cavity 11 and the width of the fresh air outlet 12 are smaller, the difference in width between the two is small, and the acceleration effect obtained when the air flows from back to front is not obvious. The speed and air supply distance are relatively small.
在一些实施例中,导流腔11的横截面在由后向前的方向上呈渐缩的形状。导流腔11的最后端在横向上的宽度W 4与导流腔11在前后方向上的深度H 4之间的比值为范围在2:11~2:9之间的任意比值。例如,宽度W 4与深度H 4之间的比值可以为2:11、2:10或2:9。由此,可以使得导流腔11后部 允许通过的气流量与能够在导流腔11内后向前地获得较佳加速的气流量之间保持合理的比例关系,避免宽度W 4与深度H 4之间的比值过小导致流向新风出风口12的气流加速不够或宽度W 4与深度H 4之间的比值过大导致流向新风出风口12底部的气流量大、新风出风口12底部的气流量小的问题。 In some embodiments, the cross section of the diversion cavity 11 has a tapered shape in a direction from back to front. The ratio between the width W 4 of the rear end of the diversion cavity 11 in the lateral direction and the depth H 4 of the diversion cavity 11 in the front and rear direction is an arbitrary ratio ranging from 2:11 to 2:9. For example, the ratio between the width W 4 and the depth H 4 may be 2:11, 2:10, or 2:9. Therefore, it is possible to maintain a reasonable proportional relationship between the air flow rate allowed to pass through the rear portion of the diversion cavity 11 and the air flow rate capable of obtaining better acceleration backward and forward in the diversion cavity 11, avoiding the width W 4 and the depth H. If the ratio between 4 is too small, the air flow to the fresh air outlet 12 is not accelerated enough, or the ratio between the width W 4 and the depth H 4 is too large, and the air flow to the bottom of the fresh air outlet 12 is large, and the air at the bottom of the fresh air outlet 12 is too large. The problem of small flow.
在一些实施例中,弧形导流板13在前后方向上的长度H 5与导流腔11在前后方向上的深度H 4之间的比值为范围在4:11~7:11之间的任意比值。可以理解的是,弧形导流板13在前后方向上的长度H 5为弧形导流板13的前端和后端在前后方向上的垂直距离。例如,长度H 5与深度H 4之间的比值可以为4:11、5:11、6:11或7:11。由此,一方面可确保导流腔11后部具有能够使得进入新风射流风道10内的大部分气流向上流动的面积,另一方面,还可确保弧形收口部111具有合理的长度,以使得对从下往上流动的部分气流进行较佳的加速,以获得较大的出风速度。反之,如果长度H 5与深度H 4之间的比值过小,则弧形收口部111对气流的加速作用不明显,新风出风口12的出风速度小。如果长度H 5与深度H 4之间的比值过大,则导流腔11内的大部分气流都会在弧形收口部111的作用下加速从新风出风口12的底部送出,导致新风出风口12底部风量大、顶部风量小的送风不匀现象。 In some embodiments, the ratio between the length H 5 of the arc-shaped deflector 13 in the front- rear direction and the depth H 4 of the deflector cavity 11 in the front-rear direction is in the range of 4:11 to 7:11. Any ratio. It can be understood that the length H 5 of the arc-shaped deflector 13 in the front-rear direction is the vertical distance between the front and rear ends of the arc-shaped deflector 13 in the front-rear direction. For example, the ratio between the length H 5 and the depth H 4 may be 4:11, 5:11, 6:11, or 7:11. As a result, on the one hand, it can be ensured that the rear portion of the diversion cavity 11 has an area capable of causing most of the airflow entering the fresh air jet duct 10 to flow upward, and on the other hand, it can also be ensured that the arc-shaped constricted portion 111 has a reasonable length. This allows for better acceleration of the part of the airflow flowing from bottom to top to obtain a larger wind speed. Conversely, if the ratio between the length H 5 and the depth H 4 is too small, the arc-shaped constricted portion 111 does not have a significant acceleration effect on the air flow, and the air outlet speed of the fresh air outlet 12 is small. If the ratio between the length H 5 and the depth H 4 is too large, most of the airflow in the diversion cavity 11 will be accelerated and sent out from the bottom of the fresh air outlet 12 under the action of the arc-shaped closing portion 111, resulting in the fresh air outlet 12 The air flow is uneven at the bottom and small at the top.
在一些实施例中,导流腔11内设有位于新风出风口12内侧的多个沿前后方向延伸的导流片14,多个导流片14在竖直方向上间隔排列,用于引导导流腔11内的气流朝向新风出风口12流动。In some embodiments, the guide cavity 11 is provided with a plurality of guide vanes 14 located inside the fresh air outlet 12 and extending in the front-to-rear direction. The plurality of guide vanes 14 are arranged at intervals in the vertical direction for guiding the guide. The air flow in the flow cavity 11 flows toward the fresh air outlet 12.
进一步地,导流片14在前后方向上的长度W 1小于等于弧形导流板13在前后方向上的长度H 5,以使得导流片14处于弧形收口部111内。也就是说,本发明在弧形收口部111内设有多个沿竖向间隔排列的多个导流片14,以便于通过弧形收口部111与导流片14的配合使得新风出风口12在竖直方向上的出风更加均匀。导流片14处在弧形收口部111内,可避免对导流腔11的后部空间内流动的气流产生前后方向的引导作用,以利于进入新风射流风道10内的气流从下往上地流动,从而利于新风出风口12处实现竖直方向上的均匀出风。 Further, the length W 1 of the baffle 14 in the front-rear direction is less than or equal to the length H 5 of the arc-shaped baffle 13 in the front-rear direction, so that the baffle 14 is in the arc-shaped constriction 111. In other words, in the present invention, a plurality of guide vanes 14 arranged at intervals in the vertical direction are provided in the arc-shaped constricted portion 111, so as to facilitate the cooperation of the arc-shaped constricted portion 111 and the guide vane 14 to make the fresh air outlet 12 The wind in the vertical direction is more even. The guide vane 14 is located in the arc-shaped constriction 111, which can prevent the airflow flowing in the rear space of the diversion cavity 11 from leading to the front and back, so as to facilitate the airflow entering the fresh air jet duct 10 from bottom to top Ground flow is beneficial to achieve uniform air discharge in the vertical direction at the fresh air outlet 12.
在一些实施例中,导流腔11内设有位于新风出风口12内侧的多个沿前后方向延伸的导流片14,多个导流片14在竖直方向上间隔排列,用于引导导流腔11内的气流朝向新风出风口12流动。进一步地,条形新风出风口12位于新风射流风道10的前侧,导流片14可包括从下至上地由后向前弯曲延伸的弧形区段141和由弧形区段141的末端向前延伸至条形新风出风口12的平直区段142。由此,可通过该特别形状的弧形区段141将由下至上流动的气流中的预设量气流保留在其内侧,并尽可能地减小该部分气流遇到弧形区段141后的流动阻力的前提下将其导流至平直区段142,通过平直区段142将该预设量的气流引导至新风出风口12,从而通过多个导流片14的配合进一步提高新风出风口12在竖直方向上的出风均匀性。In some embodiments, the guide cavity 11 is provided with a plurality of guide vanes 14 located inside the fresh air outlet 12 and extending in the front-to-rear direction. The plurality of guide vanes 14 are arranged at intervals in the vertical direction for guiding the guide. The air flow in the flow cavity 11 flows toward the fresh air outlet 12. Further, the strip-shaped fresh air outlet 12 is located on the front side of the fresh air jet duct 10, and the guide vane 14 may include an arc section 141 curved from back to front from bottom to top, and an end of the arc section 141. It extends forward to the straight section 142 of the strip-shaped fresh air outlet 12. Thereby, the preset amount of airflow in the airflow flowing from bottom to top can be kept inside the arc section 141 with the special shape, and the flow of this part of the airflow after encountering the arc section 141 can be reduced as much as possible. Under the premise of resistance, it is guided to the straight section 142, and the preset amount of airflow is guided to the fresh air outlet 12 through the straight section 142, so that the cooperation of a plurality of guide vanes 14 further improves the fresh air outlet 12 The uniformity of the wind in the vertical direction.
进一步地,本发明在导流片14邻近新风出风口12的前部特别设计有平直区段142,可通过平直区间142引导气流水平地经新风出风口12送出,由此,可使得射流装置1送出的气流与柜式空调室内机的换热气流出口送出的气流方向保持一致,从而在确保两股气流较佳的混合效果的前提下,使得柜式空调室内机的整体送风速度较高、整体送风距离较远。Further, in the present invention, a straight section 142 is specially designed on the front of the guide vane 14 adjacent to the fresh air outlet 12, and the straight section 142 can guide the air flow to be sent out horizontally through the fresh air outlet 12, thereby making the jet flow The air flow sent by the device 1 is consistent with the direction of the air flow sent from the heat exchange air outlet of the cabinet-type air conditioner indoor unit, so that the overall air supply speed of the cabinet-type air conditioner indoor unit is relatively high on the premise of ensuring a better mixing effect of the two air streams. High and long overall air supply distance.
在一些实施例中,弧形区段141在前后方向上的长度W 3大于等于平直区段142在前后方向上的长度W 2。由此,一方面,可使得弧形区段141在前后方向上具有相对较长的长度,以增大弧形区段141对气流的引导路径长度,减小弧形区段141的弯曲度,从而尽可能地减小气流遇到弧形区段141后的流动阻力。另一方面,在保证平直区段142的正常导流功能的基础上使得平直区段142在前后方向上的长度较短,以减小整个导流片14在前后方向上的长度,从而减小了射流装置1在前后方向上的尺寸,使其更适用于结构紧凑、体积要求较高的柜式空调室内机。 In some embodiments, the length W 3 of the arc-shaped section 141 in the front-rear direction is greater than or equal to the length W 2 of the straight section 142 in the front-rear direction. Thus, on the one hand, the arc-shaped section 141 can be made to have a relatively long length in the front-to-rear direction, so as to increase the guide path length of the arc-shaped section 141 to the airflow and reduce the curvature of the arc-shaped section 141. In this way, the flow resistance after the airflow encounters the arc-shaped section 141 is reduced as much as possible. On the other hand, on the basis of ensuring the normal diversion function of the straight section 142, the length of the straight section 142 in the front-to-rear direction is made shorter, so as to reduce the length of the entire baffle 14 in the front-to-rear direction, thereby The size of the jet device 1 in the front-to-rear direction is reduced, making it more suitable for a cabinet-type air conditioner indoor unit with compact structure and high volume requirements.
在一些实施例中,每个导流片14的平直区段142在前后方向上的长度均相等,每个导流片14的弧形区段141在前后方向上的长度均相等。也就是说,每个导流片14的尺寸都是相同的,以便于开模,节省成本。申请人经过深入的分析和大量的仿真、试验等验证了:只要按照上面实施例中的方案设计导流腔11、弧形导流板13和/或导流片14的尺寸,并且新风风机20持续地朝向新风射流风道 10送风,即使每个导流片14的尺寸都相同,也可以实现新风出风口12在竖直方向上的均匀出风。In some embodiments, the straight section 142 of each guide vane 14 has the same length in the front-rear direction, and the arc-shaped section 141 of each guide vane 14 has the same length in the front-rear direction. In other words, the size of each guide vane 14 is the same to facilitate mold opening and save cost. The applicant has verified through in-depth analysis and a large number of simulations and experiments: as long as the size of the diversion cavity 11, the arc-shaped deflector 13 and/or the deflector 14 is designed according to the scheme in the above embodiment, and the fresh air fan 20 The air is continuously supplied toward the fresh air jet duct 10, even if the size of each guide vane 14 is the same, the fresh air outlet 12 can be uniformly discharged in the vertical direction.
在另一些实施例中,每个导流片14的平直区段142在前后方向上的长度均相等,由下至上依次排列的多个导流片14的弧形区段141在前后方向上的长度依次增大。由此,可避免位于底部的导流片14向后伸出过长导致保留在其内侧的气流量过多进而使得导流腔11内顶部气流量少的问题,同时,还可以避免多个导流片14的弧形区段141等长可能会出现上部导流片14引导的气流量较少的问题,从而确保了新风出风口12在竖直方向上的均匀出风。In other embodiments, the straight section 142 of each guide vane 14 has the same length in the front-rear direction, and the arc-shaped sections 141 of the plurality of guide vanes 14 arranged in sequence from bottom to top are in the front-rear direction. The length increases in turn. As a result, it is possible to avoid the problem that the baffle 14 at the bottom protrudes backwards too long, resulting in too much air flow remaining inside it, thereby reducing the air flow at the top of the diversion cavity 11, and at the same time, it can also avoid multiple guides. The arc-shaped section 141 of the flow vane 14 is of equal length, which may cause the problem that the air flow guided by the upper guide vane 14 is less, so as to ensure the uniform air outlet of the fresh air outlet 12 in the vertical direction.
进一步地,多个导流片14的后端端部处于一条倾斜的直线上。也就是说,从下至上依次排的多个导流片14的弧形区段141是等间距依次延长的,进一步确保了新风出风口12在竖直方向上的均匀出风。Further, the rear ends of the plurality of guide vanes 14 are on an inclined straight line. That is to say, the arc-shaped sections 141 of the plurality of guide vanes 14 arranged from bottom to top are successively extended at equal intervals, which further ensures the uniform outlet of the fresh air outlet 12 in the vertical direction.
在一些实施例中,新风射流风道10的底部与新风风机20的顶部之间通过蜗壳风道30流体连通。新风射流风道10的进风口开设在其底部,新风风机20的气流出口位于其顶部,新风射流风道10的进风口与新风风机20的气流出口之间密封地连接有蜗壳风道30,以将新风风机20送出气流引导至新风射流风道10。通常情况下,为了获得较佳的送风范围,柜式空调室内机的送风口453、以及两个换热气流出口不会邻近地面,而是具有一定的高度。为了避免新风射流风道10的新风出风口12过低,在新风射流风道10的底部与新风风机20的顶部之间设置蜗壳风道30,以使新风射流风道10更好地与柜式空调室内机1的机壳40、贯穿通道41以及两个换热风道的结构相匹配。In some embodiments, the bottom of the fresh air jet air duct 10 and the top of the fresh air fan 20 are in fluid communication through a volute air duct 30. The air inlet of the fresh air jet duct 10 is opened at its bottom, the air outlet of the fresh air fan 20 is located at the top, and the volute air duct 30 is sealedly connected between the air inlet of the fresh air jet duct 10 and the air outlet of the fresh air fan 20, In order to guide the air flow sent by the fresh air fan 20 to the fresh air jet air duct 10. Generally, in order to obtain a better air supply range, the air supply opening 453 of the cabinet-type air conditioner indoor unit and the two heat exchange air flow outlets are not adjacent to the ground, but have a certain height. In order to prevent the fresh air outlet 12 of the fresh air jet duct 10 from being too low, a volute air duct 30 is provided between the bottom of the fresh air jet duct 10 and the top of the fresh air fan 20, so that the fresh air jet duct 10 is better connected to the cabinet. The structure of the casing 40, the through passage 41 and the two heat exchange air ducts of the air conditioner indoor unit 1 are matched.
具体地,蜗壳风道30竖向延伸。当仅有新风射流风道10可动时,蜗壳风道30可以为软质风道,以能够产生一定的弹性变形量。当新风射流风道10与新风风机20同步移动或者新风射流风道10不可动时,蜗壳风道30可以为硬质风道。Specifically, the volute air duct 30 extends vertically. When only the fresh air jet air duct 10 is movable, the volute air duct 30 can be a soft air duct to be able to produce a certain amount of elastic deformation. When the fresh air jet air duct 10 and the fresh air fan 20 move synchronously or the fresh air jet air duct 10 is immovable, the volute air duct 30 may be a hard air duct.
进一步地,蜗壳风道30在竖直方向上的高度设置成使得新风射流风道10的新风出风口12与第一换热风道和第二换热风道的换热气流出口高度相一致,以便于从新风出风口12送出的气流与从从换热气流出口流出的换热气流更好的混合。Further, the height of the volute air duct 30 in the vertical direction is set such that the fresh air outlet 12 of the fresh air jet duct 10 is consistent with the heat exchange air outlets of the first heat exchange air duct and the second heat exchange air duct. , So that the air flow sent from the fresh air outlet 12 and the heat exchange air flow out of the heat exchange air flow outlet are better mixed.
在一些实施例中,贯穿通道41沿前后方向贯穿机壳40的上部,也就是说,贯穿通道41仅形成在机壳40上部的中部。新风风机20设置在机壳40内的下部,新风管70穿过机壳40的后壁与新风风机20的气流入口密封地连接。相应地,蜗壳风道30也设置在机壳40内的下部,以避免新风风机20和蜗壳风道30裸露在外影响柜式空调室内机1的美观。In some embodiments, the through passage 41 penetrates the upper part of the casing 40 in the front-rear direction, that is, the through passage 41 is formed only in the middle of the upper part of the casing 40. The fresh air fan 20 is arranged in the lower part of the casing 40, and the fresh air pipe 70 passes through the rear wall of the casing 40 and is connected to the airflow inlet of the fresh air fan 20 in a sealed manner. Correspondingly, the volute air duct 30 is also arranged in the lower part of the casing 40 to prevent the fresh air fan 20 and the volute air duct 30 from being exposed to the outside and affecting the appearance of the cabinet-type air conditioner indoor unit 1.
将新风管70设置在机壳的下部,便于新风管70穿过墙壁与室外环境连通,新风管70可以与冷媒管、排水管一起穿过墙壁,避免在墙壁上另外打孔。The fresh air pipe 70 is arranged in the lower part of the cabinet, so that the fresh air pipe 70 can pass through the wall and communicate with the outdoor environment. The fresh air pipe 70 can pass through the wall together with the refrigerant pipe and the drain pipe to avoid additional holes in the wall.
