Specifically, the fourth rim seating part 280 includes a first seating part 281 and a second seating part 282 spaced apart from each other.

The first seat portion 281 extends from the fourth rim portion 220d to the base body 210 via the step portion 219 and may be connected to the body seat portion 215. [ On the other hand, the second seat portion 282 protrudes upward from the frame body 221 and may be spaced apart from the body seat portion 215.

The first surface (front surface) of the heat exchanger 130 may be seated in the first and second seating portions 281 and 282. The first surface of the heat exchanger 130 may be bent and extended from the third surface as a surface facing the fourth surface of the heat exchanger 130.

As described above, the main body seating portion 215 of the plurality of main body seating portions 215 and the first seating portions 251, 271, and 281 provided at the frame seating portions 250, 260, 270, and 280 are configured to be connected to each other . The main seating part 215 connected to the first seating parts 251, 271 and 281 may include a first compressor 51 or a second compressor 52 having a relatively large load among components provided in the base body 210, As shown in Fig.

The main seating part 215 and the first seating parts 251, 271 and 281 may be arranged to extend in the short side direction of the base 200.

The load or stress caused by the first and second compressors 51 and 52 that are seated in the main seating portion 215 can be transmitted to the second seating portion 225. [ The load or stress caused by the heat exchanger 130 mounted on the first seating portions 251, 271, and 281 may be transmitted to the main seating portion 215 side.

Therefore, it is possible to prevent a load or a stress due to the first or second component from concentrating on a specific region of the base 200. [ As a result, the strength of the base 200 is reinforced, and the base 200 can be prevented from being damaged.

The base 200 includes a separation unit 260 as a "spaced-apart space" for separating or separating the body seating unit 215 from the frame seating units 250, 260, 270, 280. That is, the seating portions 252, 261, 262, 263, 272, 282 of the frame seating portions 250, 260, 270, 280 may be spaced apart from the main seating portion 215 by the separation portion 260.

According to this construction, the fluid present in the base body 210 can be guided through the separating part 260 and discharged to the first drain hole 217. Therefore, there is an advantage that drainage in the base 200 can be performed smoothly.

Fig. 6 is an enlarged view of "A" in Fig. 5, and Fig. 7 is an enlarged view of "B"

Referring to FIGS. 3 to 7, the base 200 according to the embodiment of the present invention includes a plurality of drain holes. The first drain hole 217 formed in the base body 210 and the second drain holes 251a, 252a, 261a, 262a, and 263a formed in the edge mounting portions 250 and 260 are formed in the plurality of drain holes. ). A plurality of first and second drain holes may be provided, and a plurality of drain holes may be spaced apart from each other.

The second drain holes 251a, 252a, 261a, 262a and 263a are formed in the first drain hole 217 by the difference in height between the base body 210, the rim body 221 and the rim seating portions 250, 260, 270, Can be formed at a higher position.

The second drain holes 251a, 252a, 261a, 262a, and 263a are formed in the first or second edge mounting portion 250 and 260, respectively. The third and fourth edge mounting portions 270 and 280, As shown in FIG. That is, a drain hole is formed on the sides 220a and 220b forming the two short sides of the base 200, and on the side of the edge portions 220c and 220d forming the two long sides of the base 200, May not be formed.

This is because the legs 190 are provided below the rims forming the two long sides of the base 200. If a drain hole is formed in the rim of the base 200, the water may be blocked by the leg 190 and may not be drained easily.

Accordingly, the present embodiment is characterized in that the first and second frame mounting parts 250 and 260 (see FIG. 1) provided at the frame part forming two short sides of the base 200 among the frame mounting parts 250, 260, 270 and 280 provided in the frame part 220 ) Is provided with a drain hole to guide drainage of water or distilled water. In other words, the second and third surfaces of the heat exchanger 130 may be seated on the rim seating portions provided on the two short sides of the base 200 facing each other, and a drain hole may be formed on the lower side thereof.

The defrost water generated in the heat exchanger 130 is discharged to the lower side of the base 200 through the second drain holes of the first and second frame seating parts 250 and 260, And may flow to the base body 210 through the jaw 219. [ The defrost water of the base body 210 may be discharged to the lower side of the base 200 through the first drain hole 217.

The drain hole 251a formed in the first seating portion 251 of the first rim seating portion 250 and the drain hole 251a formed in the second seating hole 251a of the first rim seating portion 250 are formed in the second drain holes 251a, 252a, 261a, 262a, And a drain hole 252a formed in the drain hole 252. The drain holes 251 and 251b may be formed substantially at the center of the upper surface of the first and second seating portions 251 and 252.

The unidirectional width of the drain hole 251a of the first seating portion 251 or the drain hole 252a of the second seating portion 252 is formed as M1. Here, the term "one-way" may correspond to a direction that defines the width of the first seating portion 251 or the second seating portion 252, and the heat exchange fins 133a, 133b, 133c may be aligned.

The unidirectional width M1 may be smaller than the width w1 of the first seating portion 251 or the second seating portion 252. [

A drain hole 261a and a second seat 262a formed in the first seat portion 261 of the second frame seat portion 260 are formed in the second drain holes 251a, 252a, 261a, 262a, And a drain hole 263a formed in the third seat portion 263. The drain hole 262a is formed in the second seat portion 263a. The drain holes 261a, 262a, and 263a may be formed on the upper surfaces of the first to third seating portions 261, 262, 263.

The second and third seating portions 262 and 263 are disposed on both sides of the first seating portion 261. The drain hole 261a of the first seat portion 261 is formed to be larger than the drain hole 262a of the second seat portion 262 or the drain hole 263a of the third seat portion 263 .

As described above, the unidirectional width of the first seat portion 261 is formed to be w2, and the unidirectional width w2 of the first seat portion 251 or the second seat 251 of the first frame receiving portion 250 May be formed to be larger than the width (w1) of the portion (252).

The first seating portion 261 is provided with a first end portion 261b defining one side end of the first seating portion 261 and a second end portion 261c defining a second side end portion of the first seating portion 261 ). The first end 261b and the second end 261c may extend parallel to each other.

The unidirectional width w2 of the first seat portion 261 can be understood as a shortest distance from the first end portion 261b to the second end portion 261c.

The drain hole 261a of the first seating portion 261 may have a width of M2 based on the one direction defining the width w2 of the first seating portion 261. [ The width M2 of the drain hole 261a is larger than the width M1 of the drain holes 251a and 251b.

The shortest distance from the drain hole 261a to the first end portion 261b is H1 and the shortest distance from the drain hole 261a to the second end portion 261c is H2. The H1 is referred to as a "first shortest distance", and the H2 is referred to as a "second shortest distance".

The shortest distance H1 or the shortest distance H2 is formed to be smaller than the sum of the width of the heat exchanger 130, that is, the widths of the first to third pins 133a, 133b, 133c of the heat exchanger 130 . The size of the shortest distance H2 may be larger than the shortest distance H1.

Therefore, even when the heat exchanger 130 is aligned with the drain hole 261a, aligned with the first end 261b, or aligned with the second end 261c, At least a part of the drain hole 261a may be located below the drain hole 130a. As a result, the fluid (dehydrated water) generated from the heat exchanger 130 can be easily discharged to the drain hole 261a.

The size of the drain hole 261a may be larger than the size of the drain holes 251a and 252a. In the design of the heat exchanger 130, a portion corresponding to the second surface of the heat exchanger 130 is fixed to a predetermined size, while a portion corresponding to the third and fourth surfaces of the heat exchanger 130 Its length or alignment position may be different.

For example, depending on the length of a portion corresponding to the fourth surface of the heat exchanger 130, a portion corresponding to the third surface may be provided to approach or distant from the second surface. It is an object of the present invention to propose a drain hole structure that facilitates drainage irrespective of the position of a portion corresponding to the third surface of the heat exchanger (130).

Particularly, the size of the drain hole 261a provided in the first seating part 261 of the second rim seating part 260 is relatively large, and regardless of the installation position of the heat exchanger 130, And a drain hole may be formed on the lower side of the heat exchanger 130. Hereinafter, this will be described in detail.

The first end portion 261b is located at a position farther from the first edge mounting portion 250 than both ends 261b and 261c of the second edge mounting portion 260, . ≪ / RTI >

9, a length of the heat exchanger portion provided in the third rim seating portion 270 of the heat exchanger 130a may be relatively long.

Since the first shortest distance H1 is formed to be smaller than the width of the heat exchanger 130a even if the heat exchanger 130a is aligned with the first end 261b, And a part thereof may be positioned below the heat exchanger 130a. Therefore, the defrost water generated in the heat exchanger 130a can be discharged to the lower side of the base 200 through the drain hole 261a.

9 is a plan view showing another embodiment in which a heat exchanger is installed on the base of the outdoor unit according to the embodiment of the present invention.

The first to third pins 133a, 133b and 133c may be seated adjacent to the left portion of the second rim seating portion 225, that is, adjacent to the second end portion 261c . The left side portion may refer to a side of the opposite end portions 261b and 261c of the second frame receiving portion 260 that is closer to the first frame receiving portion 250 than a direction of the width w2 .

8, the length of the portion of the heat exchanger installed in the third rim seating portion 270 of the heat exchanger 130b may be relatively short.

In summary, referring to FIGS. 8 and 9, the mounting position of the heat exchanger 130 in the second rim seating part 260 can be changed with respect to one base 200 structure. Therefore, even if the length or size of the heat exchanger 130 is variable according to the capacity or size of the outdoor unit, the shared base 200 can be used.

The second shortest distance H2 is formed to be smaller than the width of the heat exchanger 130b even if the heat exchanger 130b is arranged closer to the second end 261c than the first end 261b. At least a part of the drain hole 261a may be positioned below the heat exchanger 130b. Therefore, the defrost water generated in the heat exchanger 130b can be discharged to the lower side of the base 200 through the drain hole 261a.
