In this embodiment, the partition plate 600 serves to partition the interior of the mobile air conditioner 10 into an outdoor side and an indoor side.

That is, of the two accommodation spaces divided by the partition plate 600, an outdoor side (heating side) corresponding to the outdoor unit in the separate air conditioner is formed in the first accommodation space disposed below the partition plate 600 , An indoor side (heat absorption side) corresponding to the indoor unit in the separate air conditioner may be formed in the second accommodation space disposed above.

Alternatively, with the opposite structure, an indoor side (heat absorption side) may be formed in the first accommodating space, and an outdoor side (heat radiating side) may be formed in the second accommodating space.

Meanwhile, a supporter 950 may be installed on the base plate 100. The supporter 950 is installed in the vertical direction on the base plate 100 and serves to support a load acting in the vertical and lateral directions on the partition plate 600 and a load acting in the lateral direction on the compression unit 200 can do.

[Cover structure]

FIG. 5 is an enlarged view showing an enlarged portion "V" of FIG. 3, FIG. 6 is a cross-sectional view taken along line "VI-VI" of FIG. 1, and FIG. 7 is a cross-sectional view taken along line "VII-VII" of FIG.

5 to 7, the mobile air conditioner 10 of the present embodiment may further include a cover 210. The cover 210 is disposed in the first accommodation space together with the compressor 202 and may be provided in a form surrounding the compressor 202 outside the compressor 202.

According to this embodiment, the cases 1000 and 1100 include a front surface (a) and a rear surface (b), a first side surface (c), and a second side surface (d). The front surface (a) is a surface forming the front appearance of the cases 1000 and 1100, and the rear surface (b) is a surface forming the rear appearance of the cases 1000 and 1100 and is disposed to face the front surface (a). In addition, the first side (c) and the second side (d) are surfaces that form the lateral appearance of the cases 1000 and 1100, and are disposed to face each other to connect the front surface (a) and the rear surface (b). to be.

The cover 210 is disposed in the first accommodation space surrounded by the front (a) and rear (b), and the first side (c) and the second side (d), and the base plate 100 together with the compressor 202 ) Can be installed. The cover 210 may include a side wall portion 220 and an upper surface portion 230.

The side wall portion 220 is formed to extend from the base plate 100 toward the discharge portion 1040, that is, from the base plate 100 toward the upper portion. The side wall portion 220 forms a barrier wall surrounding the compressor 202 in the lateral direction. Further, the upper surface portion 230 covers the open upper portion of the side wall portion 220 and is connected to the upper end of the side wall portion 220.

That is, inside the cover 210, an inner space in which the outer side of the side is surrounded by the side wall part 220, the upper part is shielded by the upper surface part 230, and the lower part is shielded by the base plate 100 is formed. In addition, the compressor 202 is accommodated in the inner space of the cover 210 formed as described above.

The side wall part 220 may include a first side wall part 221, a second side wall part 222, a third side wall part 223, and a fourth side wall part 224. The first side wall portion 221, the second side wall portion 222, the third side wall portion 223, and the fourth side wall portion 224 may be formed in a planar shape extending upward from the base plate 100. .

Among them, the first side wall portion 221 is disposed to face the front surface (a). In addition, the second side wall portion 222 is laterally connected to the first side wall portion 221 and is disposed to face the first side surface c.

In addition, the third side wall portion 223 is disposed to face the second side surface d. The third side wall portion 223 is disposed to face the second side wall portion 222, is disposed between the second side surface (d) and the second side wall portion 222, and the first side wall portion 221 and It can be connected laterally. In addition, the fourth side wall portion 224 is disposed to connect between the third side wall portion 223 and the second side wall portion 222.

According to this embodiment, the third sidewall portion 223 may be formed to have a shorter lateral length than the second sidewall portion 222. In addition, the fourth side wall portion 224 connects between the third side wall portion 223 and the second side wall portion 222 and is disposed to obliquely face the second side surface (d) and the rear surface (b). This is a design in consideration of the location of the splash fan 110 installed around the compressor 202.

The splash fan 110 is disposed on one side of the condensate flow path formed on the upper surface of the base plate 100 and may include a splash blade 111 and a splash motor 113.

The splash blade 111 is provided in a form in which a plurality of blades protrude from the outer circumferential surface of the disk provided to be rotatable. The central portion of the splash blade 111, that is, the rotation center, is connected to the splash motor 113 through a rotation shaft, and the splash blade 111 may be rotationally driven by the splash motor 113 connected in this way.

The splash fan 110 rotationally driven as described above serves to spray condensed water flowing through the flow path formed on the upper surface of the base plate 100 toward the first heat exchanger 500.

That is, when the splash fan 110 is driven to rotate, a plurality of blades protruding from the outer circumferential surface of the splash blade 111 pump up condensed water flowing through the flow path formed on the upper surface of the base plate 100 and root it toward the first heat exchanger 500 As a result, condensed water may be sprayed toward the first heat exchanger 500 by the splash fan 110.

In this way, the condensation water sprayed toward the first heat exchanger 500 by the splash fan 110 is. By lowering the temperature of the refrigerant flowing inside the first heat exchanger 500, the heat exchange efficiency made in the first heat exchanger 500 can be further improved.

The flow path formed on the upper surface of the base plate 100 and the splash blades 111 disposed in the flow path are not covered by the first heat exchanger 500 disposed thereon. And the splash motor 113 is disposed to protrude from the first heat exchanger 500 toward the compressor 202. That is, at least a portion of the splash fan 110 may be disposed between the first heat exchanger 500 and the compressor 202. In this way, a portion of the splash fan 110 disposed between the first heat exchanger 500 and the compressor 202 may be disposed closer to the compressor 202 than the third side wall part 223.

In consideration of the location of the splash pan 110, the third side wall portion 223 has a lateral length shorter than that of the second side wall portion 222, and the fourth side wall portion 224 has a second side surface (d) and The rear surface b is disposed to face obliquely and connects between the third side wall portion 223 and the second side wall portion 222.

Accordingly, the cover 210 may be wrapped around the compressor 202 while avoiding interference with the splash fan 110 disposed to protrude toward the compressor 202.

Meanwhile, in the upper surface portion 230, a through hole 230a may be formed to penetrate in the vertical direction. The passage hole 230a is provided as a passage through which the refrigerant pipe 400 connected to the compressor 202 passes through the cover 210.

The cover 210 formed as described above may cover most of the periphery of the compressor 202 except for the lower portion of the compressor 202 blocked by the base plate 100. Thereby, the compressor 202 and the accumulator 204 connected very close thereto are accommodated in an inner space surrounded by the base plate 100 and the cover 210.

As the compressor 202 is accommodated in the inner space formed by the cover 210 as described above, the degree of noise generated by the compressor 202 can be substantially reduced. That is, by blocking the surroundings of the compressor 202 by the cover 210, it is possible to substantially prevent the noise generated from the compressor 202 from being discharged to the outside of the mobile air conditioner 10.

[Arrangement structure of the open part]

On the other hand, when the compressor 202 is completely surrounded by the cover 210 as described above, noise in the high frequency band can be mainly reduced. However, as the surroundings of the compressor 202 are completely wrapped with the cover 210, noise in the high-frequency band may be reduced, and a resonance sound may be generated due to the vibration of the cover 210.

This resonance sound may be generated by vibrating the cover 210 by a sound wave emitted from the compressor 202 as the surrounding of the compressor 202 is blocked by the cover 210.

In order to prevent the occurrence of the resonant sound as described above, a configuration in which an opening 225 is provided in the cover 210 is disclosed in this embodiment. The opening 225 opens a part of the cover 210 so that a part of the inner space of the cover 210 surrounding the compressor 202 is opened to the outside of the cover 210.

The opening portion 225 may be formed in a form in which a portion of the cover 210 is cut off. More specifically, the opening portion 225 may include a through hole formed in a form in which a portion of the sidewall portion 220 penetrates in the lateral direction.

In addition, the opening portion 225 may be disposed closer to the lower end of the cover 210 among the upper end of the cover 210 adjacent to the discharge portion 1040 and the lower end of the cover 210 adjacent to the base plate 100. have.

This is a result of design considering that the sound waves emitted from the compressor 202 are mainly transmitted to the lower side of the cover 210. In addition, since the compressor 202 is installed on the base plate 100, vibrations generated from the compressor 202 can be transmitted to the cover 210 through the base plate 100, and such vibrations can be transmitted to the cover 210 In consideration of the fact that the resonance sound can be generated by vibrating, it can be understood that the factors of the resonance sound generation intensively act on the lower side of the cover 210 adjacent to the base plate 100.

In consideration of this point, in this embodiment, the opening portion 225 is disposed to be biased at the bottom of the cover 210 adjacent to the base plate 100. As the opening portion 225 is arranged to be biased at the bottom of the cover 210 as described above, factors such as sound waves or vibrations that generate a resonant sound spread throughout the cover 210 and before vibrating the cover 210 It is possible to escape to the outside of the cover 210 through 225.

Accordingly, by vibrating the cover 210, it is possible to block a significant portion of the factors that cause the resonance sound to affect the cover 210, thereby effectively mitigating the generation of the resonance sound around the compressor 202. .

In addition, the opening part 225 is disposed on the side wall part 220, and may be disposed at a position other than the first side wall part 221 and the second side wall part 222.

According to the present embodiment, the first suction port 1140 is disposed on the rear surface (b), and is disposed at a position more inclined toward the first side (c) than the second side (d). In addition, the first suction port 1140 may be disposed on the first side surface (c). In this embodiment, it is exemplified that the first suction port 1140 is disposed on the first side (c) and the rear side (b) together.

Since the first suction port 1140 is formed under the first side surface (c) and the rear surface (b), it is disposed at a position adjacent to the compressor 202, in particular, the second side wall portion 222 of the cover 210 It is disposed at a position very adjacent to the second side wall portion 222 while facing.

Considering that the first suction port 1140 forms a passage for air suction, when the opening part 225 is formed in the second side wall part 222, the noise generated from the compressor 202 is reduced to the cover 210 ) There is a result that the passage that can escape to the outside and the passage connecting the inside and the outside of the portable air purifier 10 are very closely connected.

In this case, since a passage through which the noise generated from the compressor 202 can easily escape to the outside of the mobile air purifier 10 is formed, there is a concern that the amount of noise generated by the mobile air purifier 10 may increase. Occurs.

In addition, the first side wall portion 221 is a surface facing the front surface (a) of the cases 1000 and 1100, and is a surface disposed closest to the front surface (a) of the side wall portions 220. If the opening portion 225 is disposed in the first side wall portion 221, there is a possibility that the traveling direction of the noise of the compressor 202 exiting through the opening portion 225 is toward the front of the mobile air purifier 10. It becomes higher.

Considering that the mobile air purifier 10 is typically used with the mobile air purifier 10 disposed so that the front face (a) faces the user, in the above case, the direction of the noise As the direction is directed, there is a concern that the user will feel the louder the noise.

In consideration of this point, the opening portion 225 is disposed on the side wall portion 220, and other positions other than the first side wall portion 221 and the second side wall portion 222, that is, the third side wall portion 223, and It is preferable to be disposed on at least one of the fourth side wall portions 224.

In this embodiment, the opening portion 225 is illustrated as being disposed on the fourth side wall portion 224. The fourth side wall portion 224 is to connect between the third side wall portion 223 disposed to face the second side surface (d) and the second side wall portion 222 disposed to face the first side surface (c). As to be disposed, the first heat exchanger 500 and the rear surface (b) is a side wall disposed obliquely facing each other.

This fourth side wall portion 224 is not a side wall facing the first suction port 1140 disposed on the first side (c) and the rear surface (b), but is facing the front surface (a) and adjacent to the front surface (a). It's not even the sidewalls that are so arranged. The fourth side wall portion 224 corresponds to a side wall disposed obliquely facing a region on the cases 1000 and 1100 in which a passage connecting the inside and the outside of the cases 1000 and 1100 is not formed. 1 Corresponds to a side wall disposed in a position adjacent to the heat exchanger 500 and obliquely facing the first heat exchanger 500.

When the opening portion 225 is disposed in the fourth side wall portion 224 disposed in this way, it is far from the first suction port 1140 and the front surface (a) without facing the first suction port 1140 and the front surface (a). The opening portion 225 is located in the position. Accordingly, since it is possible to suppress the high-frequency noise that can escape through the opening portion 225 from being emitted to the outside of the mobile air purifier 10, a further improved sound insulation effect can be provided.

In addition, when the opening portion 225 is disposed on the fourth side wall portion 224 as described above, the opening portion 225 is located adjacent to the first heat exchanger 500 and the first blowing unit 300 disposed around it. Can be placed in. Considering that a certain amount of noise is generated in the first blowing unit 300 as well, if the high-frequency noise exiting through the opening 225 comes out to the first blowing unit 300, the effect of this noise is reduced. 1 An effect that is offset to some extent due to the noise of the blowing unit 300 can also be expected.

In addition, the opening part 225 may be disposed on the fourth side wall part 224, and may be disposed at a position that is biased toward the third side wall part 223 than the second side wall part 222. This is a result of the design so that the opening 225 is disposed at a position further away from the first suction port 1140.

If the opening portion 225 is disposed on the third side wall portion 223 rather than the fourth side wall portion 224, the position of the opening portion 225 may be further away from the first suction port 1140, but instead It may result in the position of the opening 225 being too close to the front surface (a).

In addition, in the opening portion 225, a portion of the fourth side wall portion 224, more specifically, a portion of the fourth side wall portion 224 adjacent to the splash pan 110 is a first portion adjacent to the base plate 100. It may be formed by being cut from the lower end of the four side wall portions 224.

The opening portion 225 formed as described above is disposed adjacent to the splash pan 110, so that the cover 210 may serve to avoid interference with the splash pan 110.

And by the coupling between the other side in the lateral direction of the first cover member 210a and the other side in the lateral direction of the second cover member 210b, the connection of the second side wall portion 222 that was separated into two parts in the lateral direction can be made. have.

In addition, coupling between one side in the lateral direction of the first cover member 210a and one side in the lateral direction of the second cover member 210b may be achieved by engagement between the coupling protrusions 211a and 211b protruding from each lateral end. . Further, the coupling between the other side in the lateral direction of the first cover member 210a and the other side in the lateral direction of the second cover member 210b may be achieved through the supporter 950.

The supporter 950 is installed in the vertical direction on the base plate 100 and is provided to support a load acting in the vertical and lateral directions on the partition plate 600 and a load acting in a lateral direction on the compression unit 200 .

The supporter 950 may include a support bar 951, a first coupling portion 952 and a second coupling portion 953.

The support bar 951 forms a skeleton of the supporter 950 and is provided to have a length extending in the vertical direction, a width extending in the left and right direction, and a thickness extending in the front and rear direction. In this embodiment, the support bar 951 is illustrated as being formed in a rectangular shape elongated in the vertical direction.

The first coupling portion 952 is provided under the support bar 951. The first coupling part 952 may be formed to extend from the lower end of the support bar 951 in the thickness direction of the support bar 951. The first coupling portion 952 may be integrally formed with the support bar 951, and is coupled to the base plate 100 to couple the lower portion of the support bar 951 to the base plate 100.

The second coupling portion 953 is provided on the support bar 951. The second coupling part 953 may be formed to extend from the upper end of the support bar 951 in the thickness direction of the support bar 951. The second coupling portion 953 may be integrally formed with the support bar 951, and is coupled to the partition plate 600 to couple the upper portion of the support bar 951 to the base plate 100.

In addition, the supporter 950 may further include a third coupling portion 954 and a fourth coupling portion 955.

The third coupling portion 954 is provided on one side of the support bar 951. The third coupling portion 954 may be formed to extend from one side of the support bar 951 in the thickness direction of the support bar 951. The third coupling portion 954 may be integrally formed with the support bar 951.

The fourth coupling portion 955 is provided on the other side of the support bar 951. The fourth coupling part 955 may be formed to extend from the other side of the support bar 951 in the thickness direction of the support bar 951. The fourth coupling part 955 may be integrally formed with the support bar 951.

The supporter 950 provided in the above configuration may be coupled to the first cover member 210a and the second cover member 210b, respectively, as shown in FIGS. 10 and 11. By the coupling made between the supporter 950 and the first cover member 210a and the second cover member 210b made as described above, the other side in the lateral direction of the first cover member 210a and the lateral direction of the second cover member 210b Bonding between the other sides can be made.

Accordingly, the fourth coupling portion 955 may be coupled to the first cover member 210a. And the fourth coupling part 955 may be coupled to the second cover member 210b.

As an example, at the other end of the first cover member 210a facing the supporter 950, from the first cover member 210a so that the first curved surface 212a forms a surface parallel to the fourth coupling part 955 It is formed in a bent shape. In a state in which the first bent surface 212a and the fourth coupling part 955 are butted, the supporter 950 and the first cover member 210a may be coupled by a method of fastening with a fastening member such as a screw. .

In addition, at the other end of the second cover member 210b facing the supporter 950, the second bent surface 212b is bent from the second cover member 210b to form a surface parallel to the fourth coupling portion 955. It is formed in a shape. In a state in which the second bent surface 212b and the fourth coupling portion 955 are butted, the supporter 950 and the first cover member 210a may be coupled by a fastening member such as a screw. .

As described above, by assembling the cover 210 and installing the cover 210 in a manner in which the coupling between the cover 210 and the supporter 950 is performed together, the installation of the cover 210 can be made easily and quickly. In addition, since the cover 210 support structure in which the cover 210 is stably supported by the supporter 950 can also be added naturally, there is an advantage that the installation state of the cover 210 is maintained very stably.

Meanwhile, the upper surface portion 230 includes a cover surface 231 covering the open upper portion of the side wall portion 220, and a cover coupling surface 233 that couples the cover surface 231 with the side wall portion 220. I can. The cover surface 231 may be formed in a plane having a shape corresponding to the shape of the side wall portion 220 viewed from the top down. In addition, the cover coupling surface 233 is formed to extend downward from the edge of the cover surface 231, and is coupled to the side wall portion 220 so that the side wall portion 220 and the upper surface portion 230 are coupled to each other. do.

A through hole 230a may be formed on the upper surface portion 230, more specifically, the cover surface 231. The through hole 230a is formed to penetrate the cover surface 231 in the vertical direction, and may be formed to be open to the side of the upper surface portion 230.

That the through hole 230a is formed to be open to the side of the upper surface 230 is a result of design considering the installation structure of the compressor 202, the refrigerant pipe 400, and the cover 210.

That is, the installation of the cover 210 proceeds after the installation of the compressor 202 is completed. In general, the sidewall 220 is installed first, and then the upper surface 230 is installed later. In addition, a refrigerant pipe 400 connected to a heat exchanger is connected to the compressor 202, and if the through hole 230a is not formed to be open to the side of the upper surface 230, the upper surface 230 is the refrigerant pipe 400 There is no way to pass through and be coupled to the side wall portion 220.

In consideration of this point, in this embodiment, the through hole 230a is formed to be open to the side of the upper surface portion 230. Accordingly, the upper surface portion 230 passes through the refrigerant pipe 400 through the passage hole 230a opened to the side, so that it can be quickly and easily installed on the upper side of the side wall portion 220.

In summary, the first cover member 210a and the second cover member 210b are coupled to each other to form the sidewall portion 220 of the cover 210, and the sidewall portion 220 is coupled to the supporter 950 It is installed outside the compressor 202. In addition, the side wall portion 220 installed in this way surrounds the side portion of the compressor 202 from the outside, and the upper surface portion 230 is covered on the upper portion of the side wall portion 220 to surround the upper portion of the compressor 202 outward.

The cover 210 installed on the outside of the compressor 202 in the structure as described above, by wrapping the side and the upper portion of the compressor 202, prevents sound waves generated from the compressor 202 from being emitted to the outside of the cover 210. Suppression, and through this, it is possible to effectively block the transmission of noise generated by the compressor 202 to the outside.

[Action and effect of the cover formed with an open part]

12 is a table showing noise measurement results of a mobile air conditioner and a conventional mobile air conditioner according to an embodiment of the present invention, and FIGS. 13 to 15 are a mobile air conditioner according to an embodiment of the present invention and a conventional mobile air conditioner. This is a graph showing the noise measurement result of the harmonic.

In FIGS. 12 to 15, A shows an experiment result for a conventional mobile air conditioner, and B shows an experiment result for a mobile air conditioner according to an embodiment of the present invention. That is, A is for a mobile air conditioner to which a cover is not applied, and B is for a mobile air conditioner to which a cover is applied. The rest of the experimental conditions are the same except whether or not the cover is applied.

Hereinafter, operations and effects of the mobile air conditioner according to the present embodiment will be described with reference to FIGS. 12 to 15.

As a result of the experiment, the sound pressure measured in the conventional portable air conditioner (A) was 52.6dB in high mode, 49.28dB in medium mode, 44.88dB in low mode, and sleep ( Sleep) mode showed 43.27dB.

In contrast, the sound pressure measured in the mobile air conditioner (B) of this embodiment was 51.1dB in high mode, 47.86dB in medium mode, 42.77dB in low mode, and 40.4dB in sleep mode.

That is, it was found that the value of the sound pressure measured by the mobile air conditioner (B) of the present embodiment is about 2.9 to 6.6% lower than the sound pressure measured by the conventional mobile air conditioner (A), and the driving mode of the compressor is low. It was found that the higher the difference, the greater the difference.

In addition, in the Loudness category, it was measured to be about 5.4 to 23.1% lower in the mobile air conditioner (B) of the present embodiment than in the conventional mobile air conditioner (A). The difference was found to increase further.

In addition, in the Sharpness category, the mobile air conditioner (B) of the present embodiment was measured to be about 20.4 to 25.1% lower than the conventional mobile air conditioner (A), thereby showing a greater difference than in other items, It was also confirmed that the difference increased as the driving mode of the compressor was lowered.

These experimental results show that when the compressor is surrounded by a cover and an opening is formed in the cover, noise generated by the compressor can be more effectively blocked.

That is, the cover of the present embodiment wraps around the compressor and serves to block the propagation of noise generated by the compressor, while the generation of sound waves and vibrations generated by the compression machine can be suppressed by the opening. do.

Such a cover can very effectively provide a sound insulation effect for reducing noise generated by the compressor, and thereby, low noise of the mobile air conditioner can be realized.
