The internal motor 341 drives the crossflow impeller 342 to operate, so that the indoor air flows along the indoor air duct, thereby allowing the indoor air to pass through the indoor heat exchanger 301 for heat exchange.

需要说明的是，参照图3所示，实施例中通过在风道构件320内形成室内风道，使室内风道与室外风道隔开，避免室外空气与室内空气发生窜风；风道构件320可采用保温材料制作而成，例如上构件321和下构件322均由泡沫材料制成，具有保温作用。其中，下构件322的中部位置形成有接水盘350，室内换热器301放置在接水盘350上，室内进风口110和室内出风口120分别位于接水盘350的前后两侧，结合图4可理解到，下构件322的左右两侧的侧壁构成接水盘350左右两侧的侧壁。It should be noted that, as shown in FIG. 3 , in the embodiment, an indoor air duct is formed in the air duct component 320 to separate the indoor air duct from the outdoor air duct, thereby preventing the outdoor air from blowing into the indoor air; the air duct component 320 can be made of a heat-insulating material, for example, the upper component 321 and the lower component 322 are both made of a foam material, which has a heat-insulating effect. A water receiving pan 350 is formed in the middle of the lower component 322, and the indoor heat exchanger 301 is placed on the water receiving pan 350. The indoor air inlet 110 and the indoor air outlet 120 are respectively located on the front and rear sides of the water receiving pan 350. In combination with FIG. 4 , it can be understood that the side walls on the left and right sides of the lower component 322 constitute the side walls on the left and right sides of the water receiving pan 350.

继续参照图2和图3所示，可以理解的是，外风道组件400包括室外换热器401和外风道固定件420，室外换热器401固定在底盘100的后侧位置，外风道固定件420与底盘100固定连接，外风道固定件420设置在室外换热器401的前侧，通过外风道固件能够对室外换热器401进行支撑，外风道固定件420也可理解为外风道支架，外风道固定件420与室外换热器401之间形成送风通道，送风通道与进风通道连通形成室外风道。外风机430安装在外风道固定件420上，在外风机430的作用下，室外的空气能够依次经过室外进风口、室外风道、室外换热器401和室外出风口流动，使室外空气经过室外换热器401进行换热。Continuing to refer to FIG. 2 and FIG. 3 , it can be understood that the external air duct assembly 400 includes an outdoor heat exchanger 401 and an external air duct fixing member 420. The outdoor heat exchanger 401 is fixed at the rear side of the chassis 100. The external air duct fixing member 420 is fixedly connected to the chassis 100. The external air duct fixing member 420 is arranged at the front side of the outdoor heat exchanger 401. The outdoor heat exchanger 401 can be supported by the external air duct fixing member. The external air duct fixing member 420 can also be understood as an external air duct bracket. An air supply channel is formed between the external air duct fixing member 420 and the outdoor heat exchanger 401. The air supply channel is connected to the air inlet channel to form an outdoor air duct. The external fan 430 is installed on the external air duct fixing member 420. Under the action of the external fan 430, the outdoor air can flow through the outdoor air inlet, the outdoor air duct, the outdoor heat exchanger 401 and the outdoor air outlet in sequence, so that the outdoor air passes through the outdoor heat exchanger 401 for heat exchange.

参照图2和图3所示，可以理解的是，压缩机600周围具有管路结构，通过管路结构将压缩机600与室内换热器301和室外换热器401连接组成循环回路，从而形成整个制冷***，在制冷***中室内换热器301为蒸发器310，室外换热器401为冷凝器410，下面实施例中以蒸发器310和冷凝器410为具体示例进行说明。2 and 3 , it can be understood that there is a piping structure around the compressor 600, and the compressor 600 is connected to the indoor heat exchanger 301 and the outdoor heat exchanger 401 through the piping structure to form a circulation loop, thereby forming the entire refrigeration system. In the refrigeration system, the indoor heat exchanger 301 is the evaporator 310, and the outdoor heat exchanger 401 is the condenser 410. The evaporator 310 and the condenser 410 are used as specific examples for explanation in the following embodiments.

可以理解的是，实施例的顶置式空调器1000主要针对的使用场景是大型拖拽房车，房车室内空间大，需求冷量大，运行过程中蒸发器310会产生大量的冷凝水，因此，顶置式空调器1000需要更好的充分利用冷凝水，解决整机内部冷凝水的排水与引流防护等问题，且考虑到房车行驶过程会面临严苛的使用环境，例如在车辆行驶面临极端上下坡时的大角度倾斜，需要确保排水水路能够迅速的将冷凝水引流和排出到整机外部，并且确保冷凝水不会从房车顶部的安装口2100漏入房车室内。It can be understood that the roof-mounted air conditioner 1000 of the embodiment is mainly used in large trailer RVs. The RV has a large interior space and requires a large amount of cooling. The evaporator 310 will produce a large amount of condensed water during operation. Therefore, the roof-mounted air conditioner 1000 needs to make better use of the condensed water and solve the problems of drainage and drainage protection of the condensed water inside the whole machine. Considering that the RV will face harsh operating environments during driving, such as when the vehicle faces extreme uphill and downhill slopes and large angles, it is necessary to ensure that the drainage waterway can quickly drain and discharge the condensed water to the outside of the whole machine, and ensure that the condensed water will not leak into the interior of the RV from the installation port 2100 on the top of the RV.

参照图3和图4所示，可理解的是，底盘100的后部设有集水槽140，外风机430位于集水槽140的上方且邻近室外换热器401设置；接水盘350的左右两端的侧壁分别开设有出水口351，左右两侧的出水口351形成在下构件322的侧壁上，底盘100设有两个第一排水槽130，两个第一排水槽130分别位于室内进风口110的两侧，左侧的第一排水槽130位于左侧的出水口351的下方，右侧的第一排水槽130位于右侧的出水口351的下方，两个第一排水槽130分别与集水槽140连通，组成排水水路，接水盘350收集的冷凝水分别从左右两侧的出水口351排到第一排水槽130，然后沿第一排水槽130流入集水槽140，从而通过集水槽140可以收集蒸发器310产生的冷凝水。3 and 4, it can be understood that a water collecting tank 140 is provided at the rear of the chassis 100, and the outdoor fan 430 is located above the water collecting tank 140 and is arranged adjacent to the outdoor heat exchanger 401; the side walls of the left and right ends of the water receiving tray 350 are respectively provided with water outlets 351, and the water outlets 351 on the left and right sides are formed on the side walls of the lower member 322, and the chassis 100 is provided with two first drainage grooves 130, and the two first drainage grooves 130 are respectively located on both sides of the indoor air inlet 110, and the left side of the water receiving tray 350 is provided with a water outlet 351. The first drain groove 130 is located below the water outlet 351 on the left side, and the first drain groove 130 on the right side is located below the water outlet 351 on the right side. The two first drain grooves 130 are respectively connected to the water collecting groove 140 to form a drainage waterway. The condensed water collected by the water receiving tray 350 is discharged from the water outlets 351 on the left and right sides to the first drain groove 130, and then flows into the water collecting groove 140 along the first drain groove 130, so that the condensed water generated by the evaporator 310 can be collected by the water collecting groove 140.

需要说明的是，第一排水槽130的数量不限于两个，也可以设置一个第一排水槽130，第一排水槽130可设置在室内进风口110的左侧或右侧，接水盘350设置一个出水口351，具体根据第一排水槽130的位置进行设定。此外，出水口351设置在接水盘350的两侧端部，使得出水口351不会受到室内进风口110的进风影响，也不会影响其进风，提升进风效率；It should be noted that the number of the first drainage grooves 130 is not limited to two, and one first drainage groove 130 may be provided. The first drainage groove 130 may be provided on the left or right side of the indoor air inlet 110, and the water receiving tray 350 is provided with a water outlet 351, which is specifically set according to the position of the first drainage groove 130. In addition, the water outlet 351 is provided at both ends of the water receiving tray 350, so that the water outlet 351 will not be affected by the air intake of the indoor air inlet 110, nor will it affect its air intake, thereby improving the air intake efficiency;

结合图3可理解到，实施例中外风机430包括叶轮432和外电机431，外电机431固定安装在外风道固定件420上，通过外电机431驱动叶轮432转动，使室外空气与冷凝器410进行换热；其中叶轮432位于集水槽140上方，且叶轮432靠近冷凝器410设置，叶轮432能够与集水槽140内的冷凝水接触，叶轮432转动时能够将冷凝水打起并吹向冷凝器410表面，进一步 辅助冷凝器410散热，达到充分利用冷凝水且提升换热效率的目的。3 , it can be understood that in the embodiment, the external fan 430 includes an impeller 432 and an external motor 431, and the external motor 431 is fixedly mounted on the external air duct fixing member 420, and the impeller 432 is driven to rotate by the external motor 431, so that the outdoor air and the condenser 410 can exchange heat; wherein the impeller 432 is located above the water collecting tank 140, and the impeller 432 is arranged close to the condenser 410, and the impeller 432 can contact the condensed water in the water collecting tank 140, and when the impeller 432 rotates, the condensed water can be lifted up and blown to the surface of the condenser 410, so as to further assist the condenser 410 in dissipating heat, so as to make full use of the condensed water and improve the heat exchange efficiency.

考虑排水水路分布在底盘100的上表面，在排水和收集冷凝水时排水水路的背部会出现受冷而形成冷凝水的问题，进而可能造成冷凝水从房车车顶2000的安装口2100进入房车内部，出现房车室内漏水的现象。Considering that the drainage water channel is distributed on the upper surface of the chassis 100, the back of the drainage water channel may be cooled and condensed water may be formed when draining and collecting condensed water, which may cause the condensed water to enter the interior of the RV from the installation port 2100 of the RV roof 2000, causing water leakage in the RV.

基于此，本公开实施例对排水水路进行优化设计，当顶置式空调器1000安装于房车车顶2000时，沿垂直于底盘100方向的投影面上，第一排水槽130和集水槽140的投影分别与安装口2100的投影间隔设置，使排水水路底盘100上能够避开安装口2100在竖直方向上所对应的区域。Based on this, the embodiment of the present disclosure optimizes the design of the drainage waterway. When the roof-mounted air conditioner 1000 is installed on the roof 2000 of the RV, on the projection surface perpendicular to the direction of the chassis 100, the projections of the first drainage groove 130 and the water collection groove 140 are respectively spaced apart from the projection of the installation port 2100, so that the drainage waterway on the chassis 100 can avoid the area corresponding to the installation port 2100 in the vertical direction.

具体来说，结合图3可理解到，以房车车顶2000所在的平面作为投影面，集水槽140的投影与安装口2100的投影互不重合，集水槽140在底盘100上的背部位置不会朝向安装口2100；再结合图5可理解到，两个第一排水槽130的投影与安装口2100的投影也互不重合，且两个第一排水槽130的投影分别位于安装口2100的投影的左右两侧，使第一排水槽130在底盘100的背部位置也不会朝向安装口2100，在排水和收集冷凝水时排水水路的背部不会朝向安装口2100，有效避免排水水路背部因受冷产生的冷凝水从安装口2100滴落进入房车内部的情况出现，能够有效解决冷凝水通过安装口2100进入房车内部的问题，提升用户使用体验。其中，第一排水槽130和集水槽140的背部可理解为底盘100的底面与第一排水槽130和集水槽140对应的位置。Specifically, in combination with Figure 3, it can be understood that, with the plane where the RV roof 2000 is located as the projection plane, the projection of the water collection tank 140 and the projection of the installation port 2100 do not overlap with each other, and the back position of the water collection tank 140 on the chassis 100 will not face the installation port 2100; in combination with Figure 5, it can be understood that the projection of the two first drainage grooves 130 and the projection of the installation port 2100 also do not overlap with each other, and the projections of the two first drainage grooves 130 are respectively located on the left and right sides of the projection of the installation port 2100, so that the first drainage grooves 130 on the back position of the chassis 100 will not face the installation port 2100, and the back of the drainage waterway will not face the installation port 2100 when draining and collecting condensed water, effectively avoiding the condensed water generated on the back of the drainage waterway due to cold dripping from the installation port 2100 into the interior of the RV, which can effectively solve the problem of condensed water entering the interior of the RV through the installation port 2100, thereby improving the user experience. The back of the first drainage groove 130 and the water collecting groove 140 can be understood as the position of the bottom surface of the chassis 100 corresponding to the first drainage groove 130 and the water collecting groove 140 .

需要指出的是，参照图3所示，接水盘350处于安装口2100的上部区域，且接水盘350形成下构件322的一部分，下构件322采用泡沫材料制造而成，泡沫具有一定的厚度并具有隔热保温作用，通过接水盘350承接蒸发器310产生的冷凝水，能够隔绝冷凝水与底盘100接触，不会在接水盘350底部靠近底盘100的区域形成冷凝水，也不会造成冷凝水通过安装口2100进入房车室内的问题。It should be pointed out that, as shown in Figure 3, the water receiving pan 350 is located in the upper area of the installation port 2100, and the water receiving pan 350 forms a part of the lower component 322. The lower component 322 is made of foam material. The foam has a certain thickness and has a heat insulating effect. The water receiving pan 350 receives the condensed water generated by the evaporator 310, which can isolate the condensed water from contact with the chassis 100. Condensed water will not form in the area near the chassis 100 at the bottom of the water receiving pan 350, and there will be no problem of condensed water entering the interior of the RV through the installation port 2100.

参照图4和图5所示，排水水路还包括有两个第二排水槽150，两个第二排水槽150设置在底盘100上且位于室内进风口110的左右两侧，具体的，左侧的第二排水槽150设置在左侧的第一排水槽130靠近安装口2100的一侧，右侧的第二排水槽150设置在右侧的第一排水槽130靠近安装口2100的一侧，左右两个第二排水槽150的底部分别开设有排水孔153，排水孔153贯穿至底盘100的底面，使进入第二排水槽150的水能够排出顶置式空调器1000外。4 and 5 , the drainage waterway also includes two second drainage grooves 150, which are arranged on the chassis 100 and located on the left and right sides of the indoor air inlet 110. Specifically, the second drainage groove 150 on the left is arranged on the side of the first drainage groove 130 on the left close to the installation port 2100, and the second drainage groove 150 on the right is arranged on the side of the first drainage groove 130 on the right close to the installation port 2100. Drain holes 153 are respectively provided at the bottoms of the left and right second drainage grooves 150, and the drainage holes 153 penetrate to the bottom surface of the chassis 100, so that water entering the second drainage grooves 150 can be discharged outside the ceiling-mounted air conditioner 1000.

可以理解的是，当顶置式空调器1000安装于房车车顶2000时，第一排水槽130与第二排水槽150的投影均与安装口2100的投影间隔设置，也即是在投影面上，排水孔153的投影与安装口2100的投影不会重合，使得排水孔153排出的水不会进入到安装口2100。需要说明的是，第二排水槽150的数量根据第一排水槽130的数量进行设定，具体不作限定。It is understandable that when the roof-mounted air conditioner 1000 is installed on the RV roof 2000, the projections of the first drainage groove 130 and the second drainage groove 150 are spaced apart from the projection of the installation opening 2100, that is, on the projection surface, the projection of the drainage hole 153 does not overlap with the projection of the installation opening 2100, so that the water discharged from the drainage hole 153 does not enter the installation opening 2100. It should be noted that the number of the second drainage grooves 150 is set according to the number of the first drainage grooves 130, and is not specifically limited.

参照图5和图6所示，以右侧的第一排水槽130和第二排水槽150为示例进行说明，第一排水槽130位于接水盘350的出水口351下方，第二排水槽150位于第一排水槽130的左侧，由出水口351排出的冷凝水能够进入第一排水槽130，并沿第一排水槽130流向集水槽140。可以理解的是，当第一排水槽130的冷凝水量过多或车辆行驶过程出现颠簸等情况，第一排水槽130的水会溢出并进入第二排水槽150，通过排水孔153能够将水排出整机外部，排水孔153的位置能够避开安装口2100所在的区域，从而避免溢出的冷凝水沿安装口2100进入到房车室内，进一步降低房车在安装口2100处出现漏水的风险。Referring to FIG. 5 and FIG. 6 , the first drain groove 130 and the second drain groove 150 on the right side are used as examples for explanation. The first drain groove 130 is located below the water outlet 351 of the water receiving tray 350, and the second drain groove 150 is located on the left side of the first drain groove 130. The condensed water discharged from the water outlet 351 can enter the first drain groove 130 and flow to the water collecting tank 140 along the first drain groove 130. It can be understood that when the amount of condensed water in the first drain groove 130 is too much or the vehicle is bumpy during driving, the water in the first drain groove 130 will overflow and enter the second drain groove 150, and the water can be discharged from the outside of the whole machine through the drainage hole 153. The position of the drainage hole 153 can avoid the area where the installation port 2100 is located, thereby preventing the overflowed condensed water from entering the RV room along the installation port 2100, further reducing the risk of water leakage at the installation port 2100 of the RV.

需要说明的是，由于底盘100的底部设有安装托板700，第二排水槽150所在的位置位于第一排水槽130与安装托板700之间，使排水孔153位于安装托板700的安装区域之外，结合图6 和图12可理解到，在优选的实施例中，排水孔153靠近安装托板700的边缘设置，配合密封圈800进行密封，避免排出的冷凝水穿过安装托板700进入到安装口2100。此外，排水孔153的数量可设置有多个，多个排水孔153沿第二排水槽150的长度方向分布，有利于快速排走溢出的冷凝水，提高排水效率。It should be noted that, since the bottom of the chassis 100 is provided with a mounting bracket 700, the second drain groove 150 is located between the first drain groove 130 and the mounting bracket 700, so that the drain hole 153 is located outside the mounting area of the mounting bracket 700. In combination with Figures 6 and 12, it can be understood that in a preferred embodiment, the drain hole 153 is arranged close to the edge of the mounting bracket 700, and is sealed with a sealing ring 800 to prevent the discharged condensed water from passing through the mounting bracket 700 and entering the mounting port 2100. In addition, the number of drain holes 153 can be multiple, and the multiple drain holes 153 are distributed along the length direction of the second drain groove 150, which is conducive to quickly draining the overflowed condensed water and improving the drainage efficiency.

参照图5和图6所示，实施例中第二排水槽150靠近室内进风口110的侧壁为第一侧壁151，远离室内进风口110的侧壁为第二侧壁152，可理解到，图6中示出右侧的第二排水槽150与第一排水槽130的相对位置，第一排水槽130的冷凝水能够从第二侧壁152溢出并进入到第二排水槽150，为了避免冷凝水过多而进一步从第一侧壁151处溢出，将第一侧壁151的高度设置大于第二侧壁152的高度，且第一侧壁151与第二侧壁152的高度差h1满足大于或等于1mm，也即是第一侧壁151需高于第二侧壁152至少1mm。需要说明的是，结合图5可理解到，左侧的第二排水槽150的两侧壁的高度差为h2，高度差h2也满足大于或等于1mm，h1和h2的取值可以相同，也可以具有不同的取值，不作具体限定。Referring to FIG. 5 and FIG. 6 , in the embodiment, the side wall of the second drain groove 150 close to the indoor air inlet 110 is the first side wall 151, and the side wall away from the indoor air inlet 110 is the second side wall 152. It can be understood that FIG. 6 shows the relative position of the second drain groove 150 and the first drain groove 130 on the right side, and the condensed water of the first drain groove 130 can overflow from the second side wall 152 and enter the second drain groove 150. In order to avoid excessive condensed water from further overflowing from the first side wall 151, the height of the first side wall 151 is set to be greater than the height of the second side wall 152, and the height difference h1 between the first side wall 151 and the second side wall 152 satisfies greater than or equal to 1mm, that is, the first side wall 151 needs to be at least 1mm higher than the second side wall 152. It should be noted that, in conjunction with FIG. 5 , it can be understood that the height difference between the two side walls of the second drain groove 150 on the left side is h2, and the height difference h2 also satisfies greater than or equal to 1mm. The values of h1 and h2 can be the same or different, and are not specifically limited.

参照图5和图6所示，接水盘350的出水口351位于下构件322的侧壁的底部位置，接水盘350的端部覆盖在第二排水槽150的上方，端部朝向第二排水槽150的表面为第一端面352，且第一端面352远离第一排水槽130的一端形成有凹槽354，凹槽354的底壁为第二端面353，第一端面352与第二端面353的高度不一致，相对于第二端面353，第一端面更接近于第二排水槽150；其中，第二端面353与第一侧壁151抵接，第一端面352与第二侧壁152间隔设置，第一端面352与第二侧壁152之间具有一定的溢水间隙155，使第一排水槽130的冷凝水能够从该溢水间隙155处溢出到第二排水槽150，上述溢水间隙155的取值范围可以是大于或等于1mm，实施例中不作具体限定。5 and 6, the water outlet 351 of the water receiving tray 350 is located at the bottom of the side wall of the lower member 322, the end of the water receiving tray 350 covers the upper part of the second drainage groove 150, the surface of the end facing the second drainage groove 150 is the first end face 352, and the first end face 352 is formed with a groove 354 at one end away from the first drainage groove 130, the bottom wall of the groove 354 is the second end face 353, the height of the first end face 352 is inconsistent with the second end face 353, and the second end face 353 is not the same. 53, the first end face is closer to the second drainage groove 150; wherein, the second end face 353 is in contact with the first side wall 151, the first end face 352 is spaced apart from the second side wall 152, and a certain overflow gap 155 is provided between the first end face 352 and the second side wall 152, so that the condensed water of the first drainage groove 130 can overflow from the overflow gap 155 to the second drainage groove 150, and the value range of the above overflow gap 155 can be greater than or equal to 1 mm, which is not specifically limited in the embodiment.

考虑到整机随着车辆运行会出现突然下坡路段或急刹车等情况，整机前部严重下倾，造成整机后部集水槽140的水快速向前反向流入到左右侧的第一排水槽130内，采用上述实施例的排水水路结构确保第一排水槽130内部突然汇集大量冷凝水时，冷凝水能够越过第一排水槽130溢出到第二排水槽150内部，并迅速的排出到安装口2100的区域之外。Taking into account that the whole machine may encounter sudden downhill sections or sudden braking during operation, the front of the whole machine will tilt downward severely, causing the water in the water collection tank 140 at the rear of the whole machine to quickly flow forward and reverse into the first drainage grooves 130 on the left and right sides. The drainage waterway structure of the above embodiment is adopted to ensure that when a large amount of condensed water suddenly accumulates in the first drainage groove 130, the condensed water can overflow over the first drainage groove 130 into the second drainage groove 150 and be quickly discharged to the outside of the installation port 2100.

结合图6可理解到，第一侧壁151的顶部顶住接水盘350的底面，形成紧密的接触配合，由于接水盘350为泡沫材质，泡沫与第一侧壁151抵接时容易被压缩实现过盈装配，以形成较佳的密封结构，防止第二排水槽150突然涌过来的水太多而溢出到靠近安装口2100内侧的区域，有效避免安装口2100出现漏水的问题。In conjunction with Figure 6, it can be understood that the top of the first side wall 151 presses against the bottom surface of the water receiving tray 350 to form a tight contact fit. Since the water receiving tray 350 is made of foam material, the foam is easily compressed when it abuts against the first side wall 151 to achieve an interference fit, so as to form a better sealing structure, preventing too much water from suddenly rushing in from the second drain groove 150 and overflowing to the area inside the installation port 2100, thereby effectively avoiding water leakage at the installation port 2100.

参照图5所示，可以理解的是，当顶置式空调器1000安装于房车车顶2000时，密封圈800围绕安装口2100设置，整机安装在安装托板700顶部，沿底盘100的左右方向，安装托板700的开口710宽度为k1，安装口2100的宽度为k2，蒸发器310的宽度为k3，蒸发器310的左侧端部距离安装托板700的左侧边缘的距离为k4，安装托板700的左侧边缘距离左侧出水口351的距离为k5，蒸发器310的右侧端部距离安装托板700的右侧边缘的距离为k6，安装托板700的右侧边缘距离右侧出水口351的距离为k7，其中，安装口2100的宽度k2小于或等于开口710的宽度k1，k4、k3与k6之和大于k1，接水盘350的宽度为k5、k4、k6、k7和k3之和，使接水盘350的宽度大于安装托板700的宽度，且使第二排水槽150能够位于接水盘350的出水口351与安装托板700之间，这样排水水路的背部区域能够位于安装托板700的安装区域之外。5 , it can be understood that when the roof-mounted air conditioner 1000 is installed on the roof 2000 of the RV, the sealing ring 800 is arranged around the mounting opening 2100, and the whole machine is installed on the top of the mounting tray 700. Along the left and right directions of the chassis 100, the width of the opening 710 of the mounting tray 700 is k1, the width of the mounting opening 2100 is k2, the width of the evaporator 310 is k3, the left end of the evaporator 310 is at a distance from the left edge of the mounting tray 700 is k4, the left edge of the mounting tray 700 is at a distance from the left water outlet 351 is k5, and the right end of the evaporator 310 is at a distance from the mounting tray The distance from the right edge of the mounting plate 700 to the right water outlet 351 is k6, and the distance from the right edge of the mounting plate 700 to the right water outlet 351 is k7, wherein the width k2 of the mounting port 2100 is less than or equal to the width k1 of the opening 710, the sum of k4, k3 and k6 is greater than k1, and the width of the water receiving tray 350 is the sum of k5, k4, k6, k7 and k3, so that the width of the water receiving tray 350 is greater than the width of the mounting plate 700, and the second drainage groove 150 can be located between the water outlet 351 of the water receiving tray 350 and the mounting plate 700, so that the back area of the drainage waterway can be located outside the installation area of the mounting plate 700.

参照图6所示，可以理解的是，k5与k4之和为接水盘350的左侧壁与蒸发器310左侧的板体之间的距离，且满足k5与k4之和大于或等于20mm；k6与k7之和为接水盘350的右侧壁与 蒸发器310的右侧端部之间的距离，且满足k6与k7之和大于或等于30mm，也就是说，蒸发器310左右两侧与接水盘350两侧的出水口351距离可以设置相同的取值，也可以是两者取值不一致，考虑到蒸发器310的进出口管路设置在蒸发器310的右侧，因此，k6与k7之和的取值可大于k5与k4之和的取值，设计更加合理。6 , it can be understood that the sum of k5 and k4 is the distance between the left side wall of the water receiving tray 350 and the plate body on the left side of the evaporator 310, and the sum of k5 and k4 is greater than or equal to 20 mm; the sum of k6 and k7 is the distance between the right side wall of the water receiving tray 350 and the right side end of the evaporator 310, and the sum of k6 and k7 is greater than or equal to 30 mm, that is, the distances between the left and right sides of the evaporator 310 and the water outlets 351 on both sides of the water receiving tray 350 can be set to the same value, or the two values can be inconsistent. Considering that the inlet and outlet pipelines of the evaporator 310 are set on the right side of the evaporator 310, the sum of k6 and k7 can be greater than the sum of k5 and k4, and the design is more reasonable.

参照图5和图6所示，实施例中底盘100的底部设有止挡筋160，止挡筋160包括位于安装托板700左右两侧的第一止挡筋161和位于安装托板700前后两侧的第二止挡筋162，结合图12可理解到，第一止挡筋161用于对安装托板700的左右两侧进行定位，第二止挡筋162用于对安装托板700的前后两侧进行定位。需要说明的是，第一止挡筋161位于排水孔153与安装托板700之间，第一止挡筋161不仅具有对安装托板700限位的作用，还能够挡住排水孔153排出的冷凝水，防止冷凝水由于底盘100表面的毛细作用沿着排水孔153周围横向爬行而进入到安装托板700顶部，进而向室内进风口110和室内出风口120扩散而形成毛细导水进入室内，也就是说第一止挡筋161具有定位和防水作用。5 and 6 , in the embodiment, a stop rib 160 is provided at the bottom of the chassis 100. The stop rib 160 includes a first stop rib 161 located on the left and right sides of the mounting plate 700 and a second stop rib 162 located on the front and rear sides of the mounting plate 700. It can be understood from FIG12 that the first stop rib 161 is used to position the left and right sides of the mounting plate 700, and the second stop rib 162 is used to position the front and rear sides of the mounting plate 700. It should be noted that the first stop rib 161 is located between the drainage hole 153 and the mounting plate 700. The first stop rib 161 not only has the function of limiting the mounting plate 700, but also can block the condensed water discharged from the drainage hole 153, preventing the condensed water from crawling horizontally around the drainage hole 153 due to the capillary action of the surface of the chassis 100 and entering the top of the mounting plate 700, and then diffusing to the indoor air inlet 110 and the indoor air outlet 120 to form capillary water into the room. In other words, the first stop rib 161 has positioning and waterproofing functions.

需要说明的是，以右侧的第一止挡筋161为示例进行说明，在底盘100的左右方向上，第二排水槽150位于安装托板700与出水口351之间，也即是在k5与k7之间，第一止挡筋161靠近安装托板700的边缘，有效防止排出的冷凝水进入到安装口2100。It should be noted that, taking the first stop rib 161 on the right side as an example, in the left and right directions of the chassis 100, the second drain groove 150 is located between the mounting plate 700 and the water outlet 351, that is, between k5 and k7, and the first stop rib 161 is close to the edge of the mounting plate 700, effectively preventing the discharged condensed water from entering the mounting port 2100.

参照图7和图8所示，左右两侧的第一排水槽130的前段底壁为平面，且位于出水口351的下方，用于承接排出的冷凝水。第一排水槽130的后段从前向后倾斜延伸形成斜面131，第一排水槽130通过斜面131将冷凝水排到集水槽140，有利于向底盘100后部快速排走冷凝水，避免冷凝水在第一排水槽130的前端积聚；其中左侧的第一排水槽130的斜面131与水平面的夹角为α，右侧的第一排水槽130的斜面131与水平面的夹角为β，α与β的取值大于或等于1°，即斜面131的倾斜角度需要大于或等于1°，两侧的斜面131的倾斜角度可以相同，也可以设置为不相同。结合图13可理解到，两侧的斜面131的背部均位于安装托板700的安装区域之外，避免斜面131背部受冷产生的冷凝水进入到安装口2100。As shown in Figures 7 and 8, the front bottom wall of the first drainage grooves 130 on the left and right sides is a plane and is located below the water outlet 351, which is used to receive the discharged condensed water. The rear section of the first drainage groove 130 extends obliquely from front to rear to form an inclined surface 131. The first drainage groove 130 discharges the condensed water to the water collecting tank 140 through the inclined surface 131, which is conducive to quickly draining the condensed water to the rear of the chassis 100 and avoiding the accumulation of condensed water at the front end of the first drainage groove 130; wherein the angle between the inclined surface 131 of the first drainage groove 130 on the left side and the horizontal plane is α, and the angle between the inclined surface 131 of the first drainage groove 130 on the right side and the horizontal plane is β, and the values of α and β are greater than or equal to 1°, that is, the inclination angle of the inclined surface 131 needs to be greater than or equal to 1°, and the inclination angles of the inclined surfaces 131 on both sides can be the same or different. It can be understood from FIG. 13 that the backs of the inclined surfaces 131 on both sides are located outside the installation area of the mounting bracket 700 , so as to prevent condensed water generated by the back of the inclined surface 131 being cooled from entering the installation opening 2100 .

参照图13所示，在一些实施例中，第一排水槽130在斜面131的端部处设有收缩口，收缩口的宽度小于第一排水槽130的宽度，第一排水槽130通过收缩口与集水槽140连通，连接处的宽度收窄；也可以是第一排水槽130靠近集水槽140位置的宽度逐渐减小，也即是第一排水槽130逐渐收窄，使得大量的冷凝水从集水槽140沿着第一排水槽130向前回流时的通道缩小，减少回流的水量，从而减轻前部第二排水槽150的排水负担，降低冷凝水进入安装口2100对应区域的风险。As shown in Figure 13, in some embodiments, the first drainage groove 130 is provided with a contraction opening at the end of the inclined surface 131, and the width of the contraction opening is smaller than the width of the first drainage groove 130. The first drainage groove 130 is connected with the water collecting groove 140 through the contraction opening, and the width of the connection is narrowed; the width of the first drainage groove 130 close to the water collecting groove 140 may also gradually decrease, that is, the first drainage groove 130 gradually narrows, so that a large amount of condensed water is reduced in the channel when it flows back from the water collecting groove 140 along the first drainage groove 130, and the amount of refluxed water is reduced, thereby reducing the drainage burden of the front second drainage groove 150 and reducing the risk of condensed water entering the corresponding area of the installation port 2100.

参照图9和图11所示，底盘100的后侧沿设有后侧板170，后侧板170开设有缺口171，后侧板170的底部在缺口171处形成为集水槽140的后挡水壁172，可理解到，底盘100通过各个方向的挡水壁配合围设形成集水槽140，其中后挡水壁172的高度较小，因此当集水槽140收集的冷凝水较多时，冷凝水能够沿后挡水壁172溢出，从而排出到整机外部。9 and 11 , a rear side plate 170 is provided at the rear edge of the chassis 100, and a notch 171 is opened in the rear side plate 170. The bottom of the rear side plate 170 is formed as a rear water retaining wall 172 of the sump 140 at the notch 171. It can be understood that the chassis 100 is surrounded by water retaining walls in all directions to form the sump 140, wherein the height of the rear water retaining wall 172 is relatively small. Therefore, when the sump 140 collects a lot of condensed water, the condensed water can overflow along the rear water retaining wall 172, thereby being discharged to the outside of the entire machine.

结合图3可理解到，实施例中接水盘350的底面高于后挡水壁172，两者的高度差为h3，h3的取值大于或等于1mm，使得接水盘350产生的冷凝水能够及时向后排到集水槽140内，通过设置上述的高度差使得集水槽140内即使蓄满冷凝水，冷凝水会越过后挡水壁172排走，使接水盘350内部也不会积聚冷凝水。In conjunction with Figure 3, it can be understood that in the embodiment, the bottom surface of the water receiving tray 350 is higher than the rear water retaining wall 172, and the height difference between the two is h3, and the value of h3 is greater than or equal to 1 mm, so that the condensed water generated by the water receiving tray 350 can be discharged backward into the water collecting tank 140 in time. By setting the above-mentioned height difference, even if the water collecting tank 140 is full of condensed water, the condensed water will pass over the rear water retaining wall 172 and be discharged, so that condensed water will not accumulate inside the water receiving tray 350.

此外，可以理解的是，实施例中第二排水槽150的第一侧壁151的顶部的高度均大于后挡水壁172的顶部的高度，且高度差设计的取值大于或等于1mm，采用上述的高度差的结构，使得 即便车辆在平面路面上停车静止不动时开启空调器长期运行，后部集水槽140蓄满冷凝水，冷凝水会从整机的后沿向外溢出，或者冷凝水从第一排水槽130溢出到第二排水槽150并排出到整机外部，确保冷凝水不会进一步越过第一侧壁151向安装口2100的区域溢出，双重保护有效解决冷凝水进入安装口2100并滴落到室内的问题，当然也能更好地应对前倾时后部冷凝水大量冲向前部时能够达到防止漏水的需求。In addition, it can be understood that in the embodiments, the height of the top of the first side wall 151 of the second drainage groove 150 is greater than the height of the top of the rear water retaining wall 172, and the height difference is designed to be greater than or equal to 1 mm. The above-mentioned height difference structure is adopted, so that even if the vehicle is parked and stationary on a flat road and the air conditioner is turned on for a long time, the rear water collection tank 140 is full of condensed water, and the condensed water will overflow from the rear edge of the whole machine, or the condensed water will overflow from the first drainage groove 130 to the second drainage groove 150 and be discharged to the outside of the whole machine, ensuring that the condensed water will not further cross the first side wall 151 and overflow to the area of the installation port 2100. The double protection effectively solves the problem of condensed water entering the installation port 2100 and dripping into the room. Of course, it can also better cope with the need to prevent water leakage when a large amount of rear condensed water rushes to the front when leaning forward.

参照图9和图10所示，需要注意的是，底盘100在安装托板700的后侧沿位置设有第二止挡筋162，用于限制安装托板700在底盘100上安装时的前后位置；第二止挡筋162的背部是底盘100上向上延伸形成的前挡水壁180，从图9中可以看出前挡水壁180的高度大于后挡水壁172的高度，并且前挡水壁180的顶部被下构件322的泡沫体遮盖，形成密封结构，这样能够防止叶轮432打水溅起的冷凝水或者外部雨水从进风格栅210飞溅入时进入前挡水壁180与泡沫体之间的缝隙，进而有效避免水流沿着底盘100漏入到室内进风口110，再从安装口2100滴落入房车室内。9 and 10 , it should be noted that the chassis 100 is provided with a second stop rib 162 at the rear edge of the mounting bracket 700, which is used to limit the front and rear position of the mounting bracket 700 when installed on the chassis 100; the back of the second stop rib 162 is a front water retaining wall 180 extending upward from the chassis 100. It can be seen from FIG9 that the height of the front water retaining wall 180 is greater than the height of the rear water retaining wall 172, and the top of the front water retaining wall 180 is covered by the foam body of the lower component 322 to form a sealing structure, which can prevent condensed water splashed by the impeller 432 or external rainwater from splashing in from the air inlet grille 210 and entering the gap between the front water retaining wall 180 and the foam body, thereby effectively preventing water from leaking into the indoor air inlet 110 along the chassis 100 and then dripping into the interior of the RV from the mounting port 2100.

参照图9所示，前挡水壁180与后挡水壁172之间设有导水斜面141，结合图11可理解到，前挡水壁180的前侧为内风道组件300的安装区域，通过该内风道组件300的安装区域与安装托板700的安装区域大致对应，导水斜面141位于前挡水壁180的后侧，通过导水斜面141能够将叶轮432打起的冷凝水朝向后部回流，导水斜面141的倾斜角度可设置大于或等于1°。As shown in Figure 9, a water guiding slope 141 is provided between the front water retaining wall 180 and the rear water retaining wall 172. In combination with Figure 11, it can be understood that the front side of the front water retaining wall 180 is the installation area of the inner air duct assembly 300, and the installation area of the inner air duct assembly 300 roughly corresponds to the installation area of the mounting bracket 700. The water guiding slope 141 is located on the rear side of the front water retaining wall 180. The condensed water stirred up by the impeller 432 can be returned toward the rear through the water guiding slope 141. The inclination angle of the water guiding slope 141 can be set to be greater than or equal to 1°.

参照图11和图12，为了更详细的展示底盘100上的排水水路，图11示出底盘100的整体结构示意图，图12示出安装托板700和密封圈800在底盘100上装配后的状态图。可以理解的是，前挡水壁180的高度均高于集水槽140其他位置的挡水壁的高度，其中前挡水壁180包括前左侧挡水壁181、前中侧挡水壁182和前右侧挡水壁183，通过上述挡水壁对集水槽140的前侧进行阻挡，能够非常好的挡住大量的冷凝水，使冷凝水无法进入内风道组件300的安装区域，且无法进一步漏入房车室内。Referring to Figures 11 and 12, in order to show the drainage waterway on the chassis 100 in more detail, Figure 11 shows a schematic diagram of the overall structure of the chassis 100, and Figure 12 shows a state diagram after the mounting bracket 700 and the sealing ring 800 are assembled on the chassis 100. It can be understood that the height of the front water retaining wall 180 is higher than the height of the water retaining wall at other positions of the water collecting tank 140, wherein the front water retaining wall 180 includes a front left water retaining wall 181, a front middle water retaining wall 182 and a front right water retaining wall 183. By blocking the front side of the water collecting tank 140 through the above-mentioned water retaining wall, a large amount of condensed water can be blocked very well, so that the condensed water cannot enter the installation area of the inner air duct assembly 300, and cannot further leak into the interior of the RV.

需要指出的是，从图11和图12可理解到，排水孔153不限于设于第二排水槽150内，在底盘100上除了需要引流冷凝水的第一排水槽130、蓄水的集水槽140及安装托板700上部正对区域以外，其他区域也可根据实际应用需求设置排水孔153，例如在靠近前左侧挡水壁181位置设置排水孔153，有利于在车辆前倾时造成的整机前倾，大量冷凝水向前能够通过靠近前左侧挡水壁181处的排水孔153快速进行分流，进而排出到底盘100外部。It should be pointed out that it can be understood from Figures 11 and 12 that the drainage hole 153 is not limited to being provided in the second drainage groove 150. In addition to the first drainage groove 130 that needs to drain condensed water, the water collection groove 140 that stores water, and the area directly opposite the upper part of the mounting bracket 700 on the chassis 100, other areas may also be provided with drainage holes 153 according to actual application requirements. For example, the drainage hole 153 is provided near the front left water retaining wall 181, which is beneficial to the forward tilt of the entire machine caused by the vehicle tilting forward. A large amount of condensed water can be quickly diverted forward through the drainage hole 153 near the front left water retaining wall 181, and then discharged to the outside of the chassis 100.

参照图13所示，图13示出底盘100的正面结构示意图，两侧的第二排水槽150的前端分别设有折弯段，折弯段延伸至第一排水槽130的前侧，使第二排水槽150大致呈L形状，并能够半包围第一排水槽130；此外，第二排水槽150的底部开有多个排水孔153，便于及时排出溢进的冷凝水到底盘100外，并在相邻的排水孔153之间设置凸筋154，通过凸筋154能够加强底盘100的结构。Referring to Figure 13, Figure 13 shows a schematic diagram of the front structure of the chassis 100, and the front ends of the second drainage grooves 150 on both sides are respectively provided with bending sections, and the bending sections extend to the front side of the first drainage grooves 130, so that the second drainage grooves 150 are roughly L-shaped and can semi-surround the first drainage grooves 130; in addition, a plurality of drainage holes 153 are opened at the bottom of the second drainage grooves 150, so as to facilitate the timely discharge of overflowing condensed water to the outside of the chassis 100, and convex ribs 154 are arranged between adjacent drainage holes 153, and the structure of the chassis 100 can be strengthened by the convex ribs 154.

需要说明的是，实施例中第二排水槽150的第一侧壁151高于第二侧壁152，第一侧壁151与接水盘350底面配合形成密封结构，并结合第二排水槽150对第一排水槽130的前部进行半包围，采用上述结构能够使得整个顶置式空调器1000在蓄满水以后，面临整车突然下坡或急刹车，整机形成瞬时的前低后高状态时，集水槽140内的大量冷凝水迅速前移，第二排水槽150能够快速排出涌入的水流，避免水流进入到内风道组件300的安装区域。It should be noted that, in the embodiment, the first side wall 151 of the second drainage trough 150 is higher than the second side wall 152, the first side wall 151 cooperates with the bottom surface of the water receiving tray 350 to form a sealing structure, and combined with the second drainage trough 150, the front part of the first drainage trough 130 is semi-enclosed. The above structure enables the entire roof-mounted air conditioner 1000 to be filled with water. When the vehicle suddenly goes downhill or brakes suddenly, and the whole machine forms a transient front low and rear high state, a large amount of condensed water in the water collecting trough 140 will move forward rapidly, and the second drainage trough 150 can quickly discharge the influx of water to prevent the water from entering the installation area of the inner air duct assembly 300.

参照图13所示，在一些实施例中，底盘100上还设有第三排水槽190，第三排水槽190位于前挡水壁180靠近室内进风口110的一侧，第三排水槽190沿前挡水壁180延伸且与第二排 水槽150连通，第三排水槽190位于下构件322的安装区域，并沿着安装区域的边缘延伸至第二排水槽150处，图13的实施例示出第三排水槽190与右侧的第二排水槽150连通，第三排水槽190也可以与左侧的第二排水槽150连通，或同时连通两侧的第二排水槽150。考虑到车辆行驶出现极端情况下集水槽140的水向前溢出前挡水壁180时，通过第三排水槽190能够将溢出的水引流到第二排水槽150，防止水流进一步进入到室内进风口110。As shown in FIG. 13 , in some embodiments, a third drain groove 190 is further provided on the chassis 100 , and the third drain groove 190 is located on a side of the front water retaining wall 180 close to the indoor air inlet 110 , and the third drain groove 190 extends along the front water retaining wall 180 and is connected with the second drain groove 150 , and the third drain groove 190 is located in the installation area of the lower member 322 , and extends along the edge of the installation area to the second drain groove 150 , and the embodiment of FIG. 13 shows that the third drain groove 190 is connected with the second drain groove 150 on the right side, and the third drain groove 190 can also be connected with the second drain groove 150 on the left side, or simultaneously connected with the second drain grooves 150 on both sides. Considering that the water of the water collecting tank 140 overflows the front water retaining wall 180 forward in an extreme case of vehicle driving, the overflowed water can be diverted to the second drain groove 150 through the third drain groove 190 to prevent the water flow from further entering the indoor air inlet 110 .

参照图14所示，在一些实施例中，在集水槽140内设有温控排水阀142，底盘100设有温控排水口143与温控排水阀142连接，通过温控排水阀142能够在常温下堵住底盘100的温控排水口143，并在寒冷天气自动打开排水口，辅助实现快速排水，适用于冷暖型顶置式空调器1000，其在冬天制热需要化除冰霜快速排水。As shown in Figure 14, in some embodiments, a temperature-controlled drain valve 142 is provided in the sump 140, and the chassis 100 is provided with a temperature-controlled drain port 143 connected to the temperature-controlled drain valve 142. The temperature-controlled drain valve 142 can block the temperature-controlled drain port 143 of the chassis 100 at normal temperature, and automatically open the drain port in cold weather to assist in rapid drainage. The system is suitable for a heating and cooling type roof-mounted air conditioner 1000, which needs to defrost and drain water quickly when heating in winter.

本公开实施例还提供一种车辆，该车辆具体为房车或其它形式的车种，包括上述实施例的顶置式空调器1000。以房车为示例，顶置式空调器1000安装在房车的车顶2000，室内进风口110和室内出风口120均且与车顶2000的安装口2100相连通，实现室内侧的空气循环，整机的外部从侧面进风并朝后侧出风，实现室外侧的空气流动。在排水和收集冷凝水时排水水路的背部不会朝向安装口2100，有效避免排水水路背部因受冷产生的冷凝水从安装口2100滴落进入房车内部的情况，提升用户使用体验。The disclosed embodiment also provides a vehicle, which is specifically a motorhome or other types of vehicles, including the roof-mounted air conditioner 1000 of the above embodiment. Taking the motorhome as an example, the roof-mounted air conditioner 1000 is installed on the roof 2000 of the motorhome, and the indoor air inlet 110 and the indoor air outlet 120 are both connected to the installation port 2100 of the roof 2000 to achieve air circulation on the indoor side. The outside of the whole machine takes in air from the side and exhausts air to the rear side to achieve air flow on the outdoor side. When draining and collecting condensed water, the back of the drainage waterway will not face the installation port 2100, effectively preventing the condensed water generated by the cold on the back of the drainage waterway from dripping from the installation port 2100 into the interior of the motorhome, thereby improving the user experience.

由于车辆采用了上述实施例的顶置式空调器1000的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再赘述。Since the vehicle adopts all the technical solutions of the roof-mounted air conditioner 1000 of the above embodiment, it has at least all the beneficial effects brought by the technical solutions of the above embodiment, which will not be repeated here.

上面结合附图对本公开实施例作了详细说明，但是本公开不限于上述实施例，在所属技术领域普通技术人员所具备的知识范围内，还可以在不脱离本公开宗旨的前提下作出各种变化。The embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings, but the present disclosure is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present disclosure.
