The vehicle-mounted air conditioner is provided with an air inlet (not shown) and an air outlet (not shown), and under the action of the fan, air in the outdoor environment enters the accommodating space through the air inlet, exchanges heat with the outdoor heat exchanger and then is discharged to the outdoor environment through the air outlet. The utility model provides a vehicle air conditioner's chassis 1 is provided with at least one outlet 2 in the position that corresponds to the air outlet, can discharge the rainwater that enters into vehicle air conditioner in via the air outlet through this outlet 2 to the electrical components who sets up on chassis 1 and then lead to electrical components to damage is soaked to the rainwater. The chassis 1 of the present application is provided with a water retaining assembly 3, the water retaining assembly 3 includes a plurality of hydrophobic ribs 31, and the hydrophobic ribs 31 are substantially strip-shaped sheet structures. At least one part of the plurality of water draining ribs 31 is arranged at a position close to the water draining port 2, so when more rainwater enters the vehicle-mounted air conditioner through the air outlet, rainwater with higher speed and larger amount can be dispersed through the plurality of water draining ribs 31, the flowing speed of the rainwater is slowed down, even if the water draining port 2 cannot timely drain the rainwater, the rainwater cannot rapidly rush to other areas such as the area provided with electric elements to cause damage of the vehicle-mounted air conditioner, and the rainwater slowly flows to other areas, the water draining port 2 continuously drains water in the flowing process of the rainwater, and the rainwater can be basically drained cleanly before flowing to other areas. Like this, through the setting of outlet 2 and hydrophobic muscle 31 to can be better with the rainwater discharge that enters into in the vehicle air conditioner via the air outlet, effectively avoided because of can not in time with the water discharge lead to the vehicle air conditioner to wet, the condition emergence of short circuit damage even, ensured vehicle air conditioner's steady operation.

As shown in fig. 1, 2, 4 and 5, a part of the plurality of hydrophobic ribs 31 extends along the length direction of the chassis 1 (i.e., the left-right direction in fig. 2), and another part extends along the width direction of the chassis 1 (i.e., the up-down direction in fig. 2), so that the plurality of hydrophobic ribs 31 are disposed on the chassis 1 in a staggered manner. The hydrophobic ribs 31 arranged in a staggered mode can better disperse rainwater, slow down the flow rate of the rainwater and further can better drain the rainwater. As shown in fig. 5, the upper side of the partially hydrophobic ribs 31 is provided with notches through which rainwater can flow between the small spaces surrounded by the hydrophobic ribs 31, thereby better dispersing the rainwater. Simultaneously can also dodge each other with other parts of on-vehicle air conditioner through the notch, mutual noninterference.

On the premise of not deviating from the principle of the application, a person skilled in the art can flexibly select a specific setting form of the plurality of hydrophobic ribs 31 according to a specific application scene as long as the hydrophobic ribs 31 can disperse rainwater and slow down the flow rate of the rainwater.

As shown in fig. 1 to 5, the vehicle air conditioner further includes a mounting member 4, the mounting member 4 is disposed on the base plate 1, the mounting member 4 and the base plate 1 enclose a mounting space, and the fan and the outdoor heat exchanger are disposed in the mounting space. The air outlet is provided with a grid 5, and the grid 5 is arranged at the end part of the mounting part 4 far away from the chassis 1. Under the action of the fan, air entering the vehicle air conditioner through the air inlet is discharged through the grille 5. The air discharged through the grille 5 can flow through the outdoor heat exchanger when flowing through the installation space, and fully exchanges heat with the outdoor heat exchanger, so that the efficiency of the vehicle-mounted air conditioner can be effectively improved.

In particular, as shown in figures 1 to 5 and according to the orientation shown in figure 4, the mounting member 4 comprises two upper first portions 41 and a lower second portion 42 which abut one another, each first portion 41 having a substantially circular configuration in cross-section and the second portion 42 having a substantially rectangular configuration in cross-section. The vehicle air conditioner of the present application includes two fans which are respectively provided in two first portions 41, and the two first portions 41 are respectively provided with grilles 5 at ends away from the base chassis 1 (i.e., top ends of the first portions 41 shown in fig. 4) so as to allow air to pass therethrough. Two water outlets 2 are provided on the chassis 1 at positions corresponding to each fan so as to better discharge rainwater entering through the air outlet. The outdoor heat exchanger is disposed in the second section 42 such that the outdoor heat exchanger is disposed below the fan.

The first portion 41 may be disposed below and the second portion 42 may be disposed above, that is, the fan may be disposed below the outdoor heat exchanger. It is also possible to arrange the first and second portions 41 and 42 in a horizontal direction, i.e. to arrange the fan and the outdoor heat exchanger in a horizontal direction. Without departing from the principles of the present application, a person skilled in the art may flexibly select a specific arrangement manner of the first portion 41 and the second portion 42 according to a specific application scenario, as long as the efficiency of the vehicle-mounted air conditioner can be ensured.

It should be noted that the mounting member 4 may also include only one first portion 41 or three or four equal more first portions 41, that is, the vehicle air conditioner may include only one fan or three or four equal more fans. Obviously, the cross section of the first portion 41 and the second portion 42 can also be any possible configuration of an oval, a polygon, a profile, etc. Of course, the cross-sectional shapes of the first portion 41 and the second portion 42 may be the same, for example, the cross-sections of the first portion 41 and the second portion 42 are configured as a rectangular structure. Obviously, the mounting member 4 may not be divided into the first portion 41 and the second portion 42, but may be a single body, for example, the mounting member 4 may be a cylindrical structure which encloses the chassis 1 to form an installation space in which the fan and the outdoor heat exchanger are disposed. Without departing from the principle of the present application, a person skilled in the art can flexibly select a specific arrangement manner of the mounting member 4 according to a specific application scenario as long as the mounting member and the chassis 1 can enclose an installation space for installing the fan and the outdoor heat exchanger.

Thus, even if some rainwater cannot be discharged from the water outlet 2, the rainwater can be well dispersed through the hydrophobic ribs 31 to slow down the flow rate of the rainwater entering the other parts of the first region 11 from the gap between the lower end of the second part 42 of the mounting member 4 and the chassis 1 because the hydrophobic ribs 31 are distributed over the whole first region 11, and then the rainwater is blocked in the first region 11 by the first water blocking ribs 32 and does not flow to the second region 12. Through the setting of outlet 2, hydrophobic muscle 31, first manger plate muscle 32 like this, can avoid better making the electrical apparatus component group that sets up in second region 12 wet, the short circuit damages even because of entering into second region 12 through the rainwater in the air outlet enters into vehicle air conditioner to can ensure vehicle air conditioner's steady operation better. Obviously, the water stop assembly 3 may not include the first water stop rib 32.

As shown in fig. 1 to 5, an end of the mounting member 4 close to the first water bar 32 (i.e., a bottom end of a left portion of the second portion 42 in fig. 4) abuts an end of the first water bar 32 far from the chassis 1 (i.e., a top end of the first water bar 32 in fig. 4). The inner wall of the mounting member 4 near the end of the first water blocking rib 32 (i.e., the bottom end of the left portion of the second portion 42 in fig. 4) is provided with a guide surface 421, and the guide surface 421 is a substantially inclined surface from the inside to the outside. When the rainwater enters into vehicle air conditioner via grid 5 in, there is some rainwater to flow along the inner wall of installed part 4, some is thrown to the inner wall of installed part 4 under the effect of fan in addition, it is along the inner wall flow direction chassis 1 of installed part 4 also to have some rainwater like this, through the butt of the tip of installed part 4 and the tip of first manger plate muscle 32 and the setting of guide face 421, thereby can be with the rainwater by the inner wall guide to first manger plate muscle 32 of installed part 4, thereby block the rainwater in first region 11 better, ensure vehicle air conditioner's steady operation better. Obviously, the inner wall of the end portion of the mounting member 4 near the first water blocking rib 32 may not be provided with the guide surface 421.

In another possible embodiment, as shown in fig. 1 to 4 and 6, the end of the mounting piece 4 close to the first water bar 32 (i.e., the bottom end of the left portion of the second portion 42 in fig. 4) is lower than the end of the first water bar 32 away from the chassis 1 (i.e., the top end of the first water bar 32 in fig. 4), and at least the portion of the mounting piece 4 lower than the first water bar 32 is located on the side of the first water bar 32 close to the first region 11. According to the orientation shown in fig. 6, the left portion of the second portion 42 of the mounting member 4 is located on the right side of the first water-stop rib 32, and the bottom end of the left portion of the second portion 42 is lower than the top end of the first water-stop rib 32, for example, the bottom end of the left portion of the second portion 42 is lower than the top end of the first water-stop rib 32 by about 10mm or the like. Thus, when rainwater flows to the chassis 1 along the inner wall of the mounting member 4, even if more rainwater is splashed, the rainwater does not splash onto the first water retaining rib 32, and further does not enter the second area 12 beyond the first water retaining rib 32. And the rainwater can flow directly to the side of the first water bar 32 facing away from the second area 12, i.e. directly into the first area 11, guided by the inner wall of the mounting 4. By such an arrangement, rainwater is better blocked in the first region 11, and stable operation of the vehicle air conditioner is better ensured.

It should be noted that, on the premise of not deviating from the principle of the present application, the mounting element 4 and the first water blocking rib 32 may also be matched with each other in other manners, and a person skilled in the art may flexibly select a specific matching manner of the mounting element 4 and the first water blocking rib 32 according to a specific application scenario as long as rainwater can be blocked in the first area 11.
