A second impeller 740 is disposed between the second blowing orifice 722 and the second blowing guide 720 to force the flow of air. The second impeller 740 is rotated by the second blower motor 730 and discharges air to the second blower 725.

The second blower port 725 communicates with the discharge port 1044, and the air flows into the second blower unit 700 by the rotation of the second blower motor 730, and the discharge port 1044 communicated with the second blower port 725. It can be discharged to the room through).

On the other hand, the control box 900 may be installed on one side of the partition plate 600. The control box 900 is a place where a plurality of electrical components for controlling the operation of the mobile air conditioner 10 is embedded.

The control box 900 may be installed to penetrate through the partition plate 600. In this case, an upper portion of the control box 900 protrudes toward the upper side of the partition plate 600, and a lower portion is lower than the partition plate 600. It may protrude.

In the mobile air conditioner 10 according to the exemplary embodiment of the present invention, the rear surface of the rear case 1100 may be stepped. Specifically, the front and rear lengths of the rear case 1100 are different from each other. That is, the lower front and rear lengths of the rear case 1100 may be larger than the front and rear lengths of the upper case.

The second heat exchanger 800 is installed laterally in the second accommodating space in consideration of the flow of air and the arrangement of the components installed in the first accommodating space and the second accommodating space, which is divided into upper and lower accommodating spaces. In the first accommodating space, the first heat exchanger 500 is installed in the front and rear directions. In addition, it is because the size of the lower portion than the upper portion, and the center of gravity in the lower portion is structurally stable.

As the front and rear lengths of the lower and upper portions of the rear case 1100 are different, a step surface may be formed in the center portion of the rear case 1100, but as shown, the step surface is not formed to improve appearance quality. The lower case and the upper portion of the rear case 1100 may be formed to have a curved surface.

In addition, an exhaust port 1180 may be formed to penetrate up and down under the rear case 1100. The exhaust port 1180 is connected to the first blower port 324 and is a portion where the air exchanged in the first heat exchanger 500 is discharged, and the pipe pipe 1310 is fastened. Therefore, the exhaust port 1180 preferably has a size and shape corresponding to one end of the pipe pipe 1310.

In addition, the first suction grill 1140 described above is formed under the rear case 1100, and the first suction grill 1140 is formed only on one lower portion of the rear case 1100, as shown in the drawing. This is preferred.

That is, the first suction grill 1140 may be formed over the entire lower portion of the rear case 1100 according to the flow of air introduced into and discharged from the first accommodation space. However, when the first heat exchanger 500 is installed back and forth in the center portion of the base plate 100, the first heat exchanger 500 may be disposed at one side of the lower portion of the rear case 1100 so that the air introduced from one side may be discharged to the other side. Suction grill 1140 is formed, it is preferable that the exhaust port 1180 is formed on the other side.

The reason for forming the first suction grill 1140 only on one side of the rear case 1100 is that air sucked through the first suction grill 1140 must pass through the first heat exchanger 500. That is, to allow the air sucked from the rear through the first suction grill 1140 to pass through the side of the first heat exchanger 500 and be discharged to the rear.

A plurality of fastening protrusions for fastening with the front case 1000 are formed at the front end of the rear case 1100 so that the front and rear cases 1000 and 1100 may be fastened by passing through a fastening member such as a screw.

Alternatively, the front and rear cases 1000 and 1100 may be fastened by forming a coupling groove corresponding to the coupling protrusion and the male and female in the front case 1000 so that the coupling protrusion and the coupling groove are male and female.

The front case 1000 may form an exterior of the front surface, and form an exterior of a side surface and an upper surface. And, although not shown, the reinforcement panel may be further installed on the rear of the front case (1000).

Such a reinforcement panel may serve as sound insulation and sound absorption to absorb or block the noise generated in the mobile air conditioner 10. In addition, the reinforcement panel is preferably made of a material capable of absorbing moisture (condensed water, etc.) generated in the mobile air conditioner 10.

The front panel may be fixedly installed in the front case 1000. That is, the front panel may be fixedly mounted to the front case 1000 by the temporary assembly means and the fixing means, respectively.

7 shows a perspective view of the partition plate.

As shown in FIG. 7, the partition plate 600 has a substantially rectangular shape corresponding to the formation of the cross section of the accommodation space, and is installed in the center portion between the front case 1000 and the rear case 1100, and thus the front case. The storage space formed between the 1000 and the rear case 1100 is partitioned vertically.

The second bottom partition rib 602 prevents a plurality of parts, such as the second heat exchanger 800 installed on the upper part of the partition plate 600, from coming into close contact with the upper surface of the partition plate 600. The condensate generated and dropped at 800 forms a predetermined space so that the condensed water can easily flow on the upper surface of the partition plate 600.

 In the partition plate 600, a plurality of bottom condensation water holes 604 are formed to penetrate up and down. The bottom condensation water hole 604 allows the condensed water generated and dropped in the second heat exchanger 800 to move to the lower side of the partition plate 600.

A condensate drop guide (not shown) may be further formed on the bottom of the partition plate 600. The condensate drop guide is for smoothly falling down the condensate moving to the bottom of the partition plate 600 through the bottom condensate hole 604.

That is, the condensate drop guide serves to lure the condensed water moved to the bottom surface of the partition plate 600 to fall immediately without flowing to other parts.

Accordingly, the condensation water drop guide is formed to protrude downward from the bottom of the partition plate 600. More specifically, the condensation water drop guide extends downward from each bottom condensation water hole 604.

That is, the condensation water drop guide extends to the lower side of the bottom condensation water hole 604 and may have a cylindrical shape corresponding to the bottom condensation water hole 604.

Meanwhile, a plurality of grooves may be formed in the partition plate 600 to avoid interference with peripheral components.

In one embodiment, the front end portion of the partition plate 600 may be formed so that the control box installation port 620 is opened to the front. The control box installation port 620 is preferably molded in a size and shape corresponding to the cross section of the control box 900. Therefore, the control box 900 may be installed across the control box installation port 620 vertically.

A pipe passing groove 624 through which the refrigerant pipe 350 passes may be formed at the right end of the partition plate 600.

That is, the refrigerant flowing between the first heat exchanger 500, the compressor 202, and the second heat exchanger 800 flows by the refrigerant pipe 350 formed of a pipe, which is the refrigerant pipe 350. It is installed up and down through the pipe passing groove 624. The pipe passing groove 624 may be formed in a '⊂?' Shape (as seen from above) as shown.

Meanwhile, fastening grooves or fastening protrusions for fastening with the case may be formed near the left and right side ends of the partition plate 600.

8 is a perspective view of the baseplate.

As shown in FIG. 8, the base plate 100 may have an approximately rectangular shape corresponding to the formation of the bottom cross section of the accommodation space.

On the upper surface of the partition plate 600, a plurality of first bottom partition ribs 102 are formed. The first bottom partition rib 102 forms a space in which the condensed water can flow by forming a plurality of seals on the upper surface of the base plate 100.

In more detail, a plurality of first bottom partition ribs 102 are formed on the top surface of the base plate 100, and the condensate discharge port formed at one end of the base plate 100 is provided with condensate introduced into the top surface of the base plate 100. Can be flowed to the (130) side.

The first bottom partition rib 102 may be integrally formed with the partition plate 600 and protrude upward from an upper surface of the partition plate 600.

In addition, the first bottom partition rib 102 may prevent a plurality of parts, such as the second heat exchanger 800, installed on the upper portion of the partition plate 600 from coming into close contact with the upper surface of the base plate 100. The condensate generated and dropped in the gas 500 forms a predetermined space so that the condensed water can easily flow on the upper surface of the base plate 100.

The base plate 100 may be provided with a splash fan 110 composed of a splash wing 112 and a splash motor 114 on one side of the condensate flow path formed along the first bottom partition rib 102 formed on the upper surface. .

The splash blades 112 may be rotationally driven by the splash motor 114 having a rotation shaft connected to a central portion of the splash fan 110.

The splash wing 112 may allow the condensate flowing in the condensate flow path formed along the first bottom partition rib 102 to be sprayed toward the first heat exchanger 500.

This is to facilitate the heat exchange of the refrigerant flowing in the first heat exchanger 500 by spraying the condensed water to the first heat exchange side.

9 is a view showing a condensate drain module of the mobile air conditioner according to the present invention, Figures 10 and 11 are a partial perspective view and a partial cross-sectional view showing in detail the enlarged S region of FIG. 12 is an enlarged partial cross-sectional view of the SS region of FIG. 11.

9 to 12, the condensate drain module 400 includes a water level sensor 410, a drain pump 420, and a drain module frame 430. Here, the water level sensor 410 and the drain pump 420 may be fixed to the drain module frame 430. For reference, in another embodiment of the present invention, the drain pump 420 may be omitted.

The level sensor 410 may include a first level sensor 412 and a second level sensor 414. The first water level sensor 412 and the second water level sensor 414 may be fixed to the drainage module frame 430. The first water level sensor 412 and the second water level sensor 414 may be disposed to be spaced apart from each other, and may be disposed to have different steps.

One end of the first water level sensor 412 and one end of the second water level sensor 414 may have a difference in height by the first interval D1. The first water level sensor 412 may be disposed at a position closer to the ground than the second water level sensor 414.

In this case, the plane where the first level sensor 412 is fixed and the plane where the second level sensor 414 is fixed may be different from each other.

In addition, the first water level sensor 412 and the second water level sensor 414 may be fixed on the drainage module frame 430 so as to be spaced apart from each other by a second distance D2.

Since the first level sensor 412 and the second level sensor 414 have the same components, the first level sensor 412 will be described as an example.

The first water level sensor 412 includes a floating portion 412f having a specific gravity lower than that of condensed water, and a pillar portion 412l for guiding the floating portion 412f up and down. The floating portion 412f has a donut shape and may move up and down along the filler portion 412l in a form in which the filler portion 412l is inserted into the center of the hollow.

Upper and lower guard portions 412a and 412b are formed on the upper and lower portions of the filler portion 412l so that the floating portion 412f is not separated from the pillar portion 412l. In this case, one surface of the upper guard part 412a may be disposed to contact the drainage module frame 430.

The floating portion 412f may move up and down along the pillar portion 412l in a region between the upper guard portion 412a and the lower guard portion 412b.

The sensing unit 412s is provided in an area between the upper guard portion 412a and the lower guard portion 412b of the pillar portion 412l. The sensing unit 412s generates a detection signal by sensing the floating unit 412f when the floating unit 412f overlaps the sensing unit 412s. The generated detection signal is transmitted to the control box 900.

For example, the floating unit 412f may include a magnet, and the sensing unit 412s detects a change in the magnetic flux player, and provides a detection signal to the control box 900 when the floating unit 412f overlaps. You can print However, this is only one example, and the present invention is not limited thereto.

That is, the first water level sensor 412 may detect the position of the floating portion 412f through the sensor portion 412s disposed on a certain height of the pillar portion 412l, and the floating portion 412f may be a sensor portion. When overlapping at 412s, the first water level sensor 412 may determine that the current water level is higher than the position of the sensor unit. In this case, the first level sensor 412 and the second level sensor 414 include substantially the same components and may operate in substantially the same manner.

Here, the first level sensor 412 may detect the first level, and the second level sensor 414 may detect the second level higher than the first level. Since the first water level sensor 412 and the second water level sensor 414 are disposed at different heights, the height of the water level that can be detected is also different.

The first and second water level sensors 412 and 414 transmit a detection signal to the control box 900 indicating that the condensate has reached a certain level when the level of the condensate exceeds a predetermined level. The control box 900 may control the operation of each component included in the mobile air conditioner 10 based on the received data. Detailed description thereof will be described later.

The drain pump 420 may discharge the condensed water accumulated in the base plate 100 to the outside through the drain pipe 450. The drain pump 420 may include a compression pump generating a high pressure, and may move the condensed water to the outside using the generated pressure. At this time, the condensed water may be discharged to the outside through the drain pipe 450 connected to one side of the drain pump 420.

The drain module frame 430 fixes the water level sensor 410 and the drain pump 420. The drainage module frame 430 may include a drainage module fixing plate 435 in which the first water level sensor 412 and the second water level sensor 414 are installed. In this case, the drainage module fixing plate 435 may have a first spacing ( It may be formed to have a step as D1).

In this case, the drainage module frame 430 may be integrally formed with the first blowing guide 322 of the first blowing unit 300.

The drain module frame 430 may be formed in the same process (eg, a press molding process) as the first blowing guide 322, and may be made of the same material.

As the drainage module frame 430 and the first blowing guide 322 are integrally formed, a separate fixing frame for fixing the water level sensor 410 and the drain pump 420 is omitted in the mobile air conditioner 10. Can be.

Through this, the mobile air conditioner 10 can reduce the total number of parts of the condensate drain module 400, it can omit the additional assembly maneuver generated by having a separate fixed frame. In addition, the manufacturing cost can be reduced by simplifying the assembly structure of the water level sensor 410 and the drain pump 420.

One end of the drain pipe 450 may be connected to the drain pump 420, and the other end thereof may be connected to a discharge port facing outward. The drain pipe 450 may be arranged to be curved along the outer surface of the first blowing guide 322. That is, the drain pipe 450 is disposed to be in contact with the upper surface of the first blowing guide 322, and is arranged to bend along the curvature of the upper surface. The arrangement of the drain pipe 450 may simplify the internal structure of the mobile air conditioner 10, and reduce the overall size of the mobile air conditioner through wiring arrangement.

FIG. 13 is a cross-sectional view taken along line A-A of FIG. 11, and FIG. 14 is a cross-sectional view taken along line B-B of FIG. 11.

As shown in FIG. 13, the drain pump 420 may be fixed to an inner surface of the upper plate of the drain module frame 430. The drain pump 420 may be fixed to the inner surface of the drain module frame 430 by the coupling member 431 (for example, a bolt). In this case, the drainage module frame 430 may be disposed to cover the upper portion of the drainage pump 420 so that condensed water does not penetrate into the internal circuit of the drainage pump 420.

As shown in FIG. 14, the drainage module fixing plate 435 may further include fixing grooves 432 and 434 into which the first water level sensor 412 and the second water level sensor 414 may be inserted. .

The first level sensor 412 may be inserted into and fixed in the first fixing groove 432, and the second level sensor 414 may be inserted into and fixed in the second fixing groove 434. In this case, each of the fixing grooves 432 and 434 may be arranged to be spaced apart by the second interval D2.

Although not clearly shown in the drawings, a plurality of wires respectively connected to the water level sensor 410 and the drain pump 420 may be disposed to pass through the opening 437 formed at the side of the drain module frame 430. The plurality of wires may be connected to the control box 900 to transmit a signal between the water level sensor 410 and the drain pump 420 and the control box 900.

15 and 16 are views for explaining the operation of the drain pump of the mobile air conditioner according to the embodiment of the present invention.

15 and 16, one end of the drain pipe 450 may be connected to the drain pump 420 and the other end may be connected to a discharge port connected to the outside. The drain pump 420 discharges the condensed water collected in the base plate 100 to the outside through the drain pipe 450. The condensed water moves upward along the drain pipe 450 and is discharged to the discharge port connected to the other end of the drain pipe 450.

The drain pipe 450 may be arranged to be curved along the outer surface of the first blowing guide 322. The drain pipe 450 is disposed to contact the upper surface of the first blowing guide 322 and is arranged to bend along the curvature of the upper surface.

In this case, the drain pipe 450 may be disposed to pass between the partition plate 600 and the first blowing guide 322, and may be connected to a discharge hole that passes to the outside of the mobile air conditioner 10. Although not clearly shown in the drawings, one side of the discharge port is provided with a storage container for storing the discharged condensate, it is possible to collect the discharged condensate.

17 to 19 are views for explaining the operation of the mobile air conditioner according to an embodiment of the present invention and the flow of air accordingly.

17 to 19, looks at the operation of the mobile air conditioner 10 according to the present invention as described above.

First, the flow of the refrigerant and air in the mobile air conditioner 10 according to the present invention will be described.

The mobile air conditioner 10 according to the present invention can be used for cooling or heating. Here, the mobile air conditioner 10 according to the present invention will be described as an example as described above.

In this case, the first heat exchanger 500 serves as a condenser, and the second heat exchanger 800 serves as an evaporator. In addition, a refrigerant pipe 350 is connected between the compressor 202, the first heat exchanger 500, and the second heat exchanger 800 to guide the flow of the refrigerant.

Therefore, when the gaseous refrigerant is compressed from the compressor 202 to a state of high temperature and high pressure and flows into the first heat exchanger 500, the refrigerant is condensed by heat exchange with the outside air in the first heat exchanger 500.

Then, the condensed refrigerant expands while passing through the expansion valve, and flows into the second heat exchanger 800.

The refrigerant introduced into the second heat exchanger 800 evaporates by exchanging heat with external air. Therefore, the refrigerant is in a gaseous state, in which a liquid refrigerant also remains, and in fact, two-phase refrigerants are mixed.

The refrigerant flows back to the compressor 202 after passing through the accumulator 203 to complete a cycle of the refrigerant.

Meanwhile, the air exchanges heat while passing through the first heat exchanger 500 and the second heat exchanger 800.

First, look at the air flow (indicated by the black arrow in the drawing) on the heat dissipation side (first receiving space). Air flow at this time is basically generated by the first impeller 340.

That is, when the first blower motor 330 is driven by a power source applied from the outside, the first impeller 340 connected to the shaft of the first blower motor 330 rotates to generate air flow. will be.

Therefore, the rear air may be introduced through the first suction port 1130 formed at the lower portion of the rear case 1100. The air flowing through the first intake port 1130 is changed in direction and flows laterally, and passes through the first heat exchanger 500.

The air passing through the first heat exchanger 500 rises in temperature. That is, since the first heat exchanger 500 serves as a condenser, the air is heated to a high temperature by receiving heat from the refrigerant flowing in the first heat exchanger 500.

The hot air passing through the first heat exchanger 500 passes through the first blowing orifice 323 and flows into the center of the first impeller 340. The air introduced into the center of the first impeller 340 flows radially by the rotation of the first impeller 340 and is guided in the first blowing guide 322 and the first blowing orifice 323 and discharged upward.

The hot air guided in the first blowing guide 322 and the first blowing orifice 323 and discharged upward is completely discharged to the outside of the building through the pipe 1300.

Next, the flow of air occurring on the endothermic side (second receiving space) (indicated by a white arrow in the drawing) is examined. Air flow at this time is basically generated by the second impeller 740.

That is, when the second blower motor 730 is driven by the power applied from the outside, the second impeller 740 connected to the shaft of the second blower motor 730 rotates to generate air flow. will be.

Therefore, the outside air flows into the first accommodation space through the second suction port 1110 formed on the rear case 1100. The air flowing through the second suction port 1110 passes through a filter installed at the second suction grill 1120 and the second suction port 1110, and foreign matters or odors in the air may be removed in the process.

The air introduced into the second receiving space passes through the second heat exchanger 800, and heat exchange occurs in this process. That is, since the second heat exchanger 800 acts as an evaporator, the air passing through the second heat exchanger 800 is cooled by heat exchange with the refrigerant.

The low temperature air passing through the second heat exchanger 800 flows through the second blowing orifice 722 and flows into the center of the second impeller 740. The air introduced into the center of the second impeller 740 is discharged radially by the rotation of the second impeller 740, the air is guided in the second air blowing guide 721 and the second air blowing orifice 722, the upper side To flow.

The air that is guided in the second blowing guide 721 and the second blowing orifice 722 and flows upward passes through the discharge louver 750 through the second blowing hole 725. The low-temperature air passing through the discharge louver 750 may be discharged while the direction is changed, so that the indoor space may be smoothly cooled.

Next, look at the condensate flow.

In the second heat exchanger 800, heat exchange occurs between the outside air and the internal refrigerant, and in this process, water in the air condenses to generate condensed water.

The condensed water generated in this process descends to the bottom of the second heat exchanger 800 and falls on the upper surface of the partition plate 600. The condensed water dropped on the upper surface of the partition plate 600 is guided and flows by the second bottom partition rib 602, and moves downward through the partition plate 600 through the bottom condensation hole 604 in the process. do.

The condensed water that has passed through the bottom condensation water hole 604 and moves to the lower side of the partition plate 600 flows along the inner surface of the condensate drop guide, falls to the bottom of the condensate drop guide, and then falls downward.

The condensed water dropped downward may flow into the upper surface of the base plate 100. The condensed water introduced into the upper surface of the base plate 100 may flow along a flow path formed by the first bottom partition rib 102 formed in the upper surface of the base plate 100.

The splash fan 110 may spray the condensate flowing through the flow path of the condensate formed along the first bottom partition rib 102 to the first heat exchanger 500. This is to facilitate the heat exchange of the refrigerant flowing in the first heat exchanger 500 by spraying the condensed water to the first heat exchange side, and to discharge the condensed water to the outside.

The control box 900 may control the operation of each component of the mobile air conditioner 10 according to the level of the condensate collected in the base plate 100.

In detail, the control box 900 receives a detection signal for the level of condensate from the level sensor 410. As described above in detail, the water level sensor 410 may detect the first water level and the second water level. At this time, the second water level is set higher than the first water level.

When the level of the condensate is lower than the first level, the mobile air conditioner 10 operates normally. In this case, the splash fan 110 may operate at a low speed (eg, 2200 RPM). However, this is only one example, and the present invention is not limited thereto.

When the level of the condensate is higher than the first level and lower than the second level, the control box 900 increases the driving speed of the splash fan 110. Through this, a larger amount of condensate flowing in the condensate flow path may be sprayed toward the first heat exchanger 500, and a portion of the sprayed condensate receives heat from a refrigerant flowing inside the first heat exchanger 500. Evaporates. In this case, the splash fan 110 may operate at a high speed (for example, 4400 RPM). However, this is only one example, and the present invention is not limited thereto.

The hot air including the evaporated condensed water passing through the first heat exchanger 500 passes through the first blowing orifice 323 and flows into the center of the first impeller 340. The air introduced into the center of the first impeller 340 flows radially by the rotation of the first impeller 340 and is guided in the first blowing guide 322 and the first blowing orifice 323 and discharged upward.

The hot air guided in the first blowing guide 322 and the first blowing orifice 323 and discharged upward is completely discharged to the outside of the building through the pipe 1300.

In this case, the control box 900 may control the operation of the compressor 202 so that the temperature of the refrigerant supplied to the first heat exchanger 500 operating as the condenser increases. As the temperature of the refrigerant rises, more of the condensate may evaporate and be discharged to the outside.

In addition, the control box 900 may reduce the amount of condensate generated in the first heat exchanger 500 by lowering the operating speed of the condenser.

In addition, the control box 900 may increase the rotation speed of the first impeller 340 in order to quickly discharge the condensed water evaporated to the outside.

On the other hand, when the level of the condensate is higher than the second level, the control box 900 may drive the drain pump 420 to discharge the condensate to the outside through the drain pipe 450. This is to discharge the condensed water to the outside quickly when the drainage is not made smoothly by only the operation speed control of the splash fan 110 or the compressor 202 to reach full water. In this case, the control box 900 may stop the operation of the compressor 202 or stop the operation of the entire component except the drain pump 420, but the present invention is not limited thereto.

The control box 900 operates the drain pump 420 only when the level of the condensate is higher than the second level, thereby minimizing the operation of the drain pump 420 in the process of discharging the condensate. By minimizing the operation of the drain pump 420 having a relatively high operating noise and a large amount of power used, the operating noise and the amount of power used in the portable air conditioner can be reduced, and energy efficiency can be improved.

Additionally, in another embodiment of the present invention, the control box 900 stops all the operations of the mobile air conditioner 10 when the level of the condensate is higher than the second level, and notifies the user of full water (for example, , A notification sound or a notification display).

What has been described above is only embodiments for carrying out the present invention, and the present invention is not limited to the above embodiments, and the present invention is not limited to the scope of the present invention as claimed in the following claims. Anyone with ordinary knowledge in the field of the present invention will have the technical idea of the present invention to the extent that various modifications can be made.
