In the present embodiment, the electric heating pipe and the condenser body 41 are arranged in parallel with each other. Thus, the above arrangement makes the heating efficiency of the electric heating pipe to the condenser body 41 consistent everywhere to heat the surface of the condenser body 41 uniformly, further preventing the frost or ice from forming on the condenser 40.

The electric heating tube and the condenser body 41 are arranged in parallel to each other, which means that the center axis of the electric heating tube and the plate surface of the condenser body 41 are arranged in parallel to each other.

Optionally, there is one electric heating tube; alternatively, the electric heating pipe may be provided in plurality, and the plurality of electric heating pipes may be arranged at intervals in the height direction of the condenser 40. Like this, above-mentioned setting makes the number of motor heat pipe select more in a flexible way to satisfy different user demand and operating mode, also promoted staff's processing flexibility.

In the present embodiment, the electric heating pipe is plural, and the plural electric heating pipes are arranged at intervals in the height direction of the condenser 40. Thus, the heating area of the electric heating pipe is increased by the arrangement, the heating efficiency of the electric heating pipe is further improved, and the condenser 40 is further prevented from frosting or freezing.

As shown in fig. 4, the casing 10 includes a chassis 11 and a first base 12. The first base 12 is disposed on the chassis 11, the fan 60 and the condenser 40 are disposed on the first base 12, the first base 12 has a drain hole 121, and at least a portion of the drain hole 121 is located below the condenser 40. Wherein, the drain hole 121 is one; alternatively, a plurality of water discharge holes 121 may be provided, and the plurality of water discharge holes 121 may be spaced apart in the longitudinal direction and/or the width direction of the first base 12. In this way, drain holes 121 are used to drain melted ice water onto chassis 11, thereby preventing such ice water from flowing onto fan 60 and/or condenser 40 to affect the normal operation of both. Meanwhile, the number of the drain holes 121 can be selected more flexibly by the arrangement, so that different use requirements and working conditions can be met, and the processing flexibility of workers can be improved.

Alternatively, the number of the drainage holes 121 may be plural, and the plurality of drainage holes 121 are disposed at intervals along the length direction of the first base 12. Along the length direction of the first base 12, the area of the drain holes 121 at the two ends is larger than that of the drain hole 121 at the middle part, so that the motor home can drain water timely and effectively under different road conditions, and ice water formed after ice is melted can be drained from the drain holes 121 smoothly.

In this embodiment, the chassis 11 is synchronously provided with the through holes, and since the outdoor unit of the vehicle-mounted air conditioner is installed on the top of the motor home and a sufficient space gap is formed between the through holes on the chassis 11 and the top of the motor home, the water after being frozen and melted can be timely and finally discharged from the chassis.

Alternatively, the drainage hole 121 is a polygonal hole, or a circular hole, or an elliptical hole.

Wherein the first recess 122 and at least part of the second recess 123 are located below the condenser 40. Thus, the melted ice water directly falls into first recess 122, part of the ice water is discharged onto base plate 11 through water discharge hole 121, and part of the ice water is buffered in the space of first recess 122 excluding water discharge hole 121. Therefore, after the ice water in the first concave part 122 is not timely discharged from the water discharge hole 121 and the buffer memory reaches a certain height, the ice water firstly overflows into the second concave part 123 to buffer the overflowing ice water through the second concave part 123 until the ice water is discharged from the water discharge hole 121, and the ice water is further prevented from overflowing onto the fan 60 and the condenser 40 to influence the normal operation of the two.

Specifically, the first concave portion 122 is a groove, the second concave portion 123 is a concave portion, and the groove depth of the groove is greater than the depth of the concave portion, so as to ensure that ice water which is not discharged from the drain hole 121 in time and has a certain height overflows into the concave portion for buffering, and avoid the ice water from directly overflowing onto the fan 60 and the condenser 40.

As shown in fig. 4, the first chassis 12 is provided with a liquid baffle 13, and the liquid baffle 13 is located between the condenser 40 and the evaporator and around at least a portion of the second recess 123. In this way, the liquid blocking plate 13 can block the ice water buffered in the second recess 123, so as to ensure that the ice water can be buffered in the second recess 123 and only be discharged from the water discharge hole 121 onto the chassis 11.

Optionally, the height of the liquid baffle 13 is greater than or equal to 15mm and less than or equal to 25mm. Thus, the above arrangement ensures that the liquid baffle 13 can function as a water collecting function.

In the present embodiment, the height of the liquid baffle 13 is 20mm.

It should be noted that the height of the liquid baffle 13 is not limited to this, and can be adjusted according to the working condition and the use requirement. Optionally, the height of the liquid barrier 13 is 18mm, or 22m, or 24mm.
