Description

Mobile air conditioner {MOVABLE AIR CONDITIONER}

The present invention relates to a mobile air conditioner, and more particularly, to a mobile air conditioner capable of cooling a condenser using condensate generated when indoor air is air-conditioned.

In general, a mobile air conditioner has a form in which components such as a compressor, an evaporator (generally an indoor heat exchanger), an expansion valve, and a condenser (generally an outdoor heat exchanger) are integrally included in a single product.

A mobile air conditioner can be manufactured as a single product by arranging an evaporator (indoor heat exchanger) and a condenser (outdoor heat exchanger) in a partitioned space so that it can be easily moved and installed.

Unlike general air conditioners in which an outdoor unit is provided separately, a mobile air conditioner has an advantage in that an evaporator and a condenser are installed and manufactured in a single product, so that consumers can install them by themselves and that mobile installation is easy.

In general, a mobile air conditioner performs only a cooling function of cooling indoor air, but a cooling cycle and a heating cycle may be switched by enabling reverse circulation of a refrigerant.

In recent years, the development and distribution of mobile air conditioners having moving wheels attached to the bottom so that users can easily move them have been actively developed.

Since the mobile air conditioner is easy to move and install, the user can easily place and install the mobile air conditioner in a desired place without the help of an expert who has acquired separate installation skills.

The mobile air conditioner does not require separate construction for installation, and the user can easily move and install the mobile air conditioner, thereby saving installation costs.

The mobile air conditioner may be used in a state of being mounted on the floor rather than being installed on a wall or ceiling as in the prior art. Therefore, after the evaporator partitions the space inside the mobile air conditioner vertically so that the air-conditioned air can be discharged upward, the evaporator is disposed on the upper side and the condenser is disposed on the lower side.

The condenser is a part where the refrigerant, which has become a high-temperature and high-pressure gaseous state in the compressor, flows and exchanges heat with the air passing through the condenser to condense the refrigerant. Therefore, the temperature of the air that exchanges heat with the refrigerant rises, and the air that exchanges heat with the refrigerant is discharged to the outdoors.

It is important to cool the condenser to improve cooling efficiency. This is because the refrigerant cooled in the cooler flows through the evaporator through the condenser and discharges the cooled air into the room while passing through the evaporator.

Mobile air conditioners tend to be miniaturized so that they can be easily moved and installed. Parts constituting the mobile air conditioner are efficiently arranged inside the mobile air conditioner so that numerous components can be installed inside the miniaturized product.

The accommodating space provided inside the mobile air conditioner is very narrow, and since numerous parts for driving the mobile air conditioner are installed, it is difficult to cool the condenser. Therefore, a method for efficiently cooling the condenser is required.

An object of the present invention is to efficiently cool heat generated from a condenser installed in a receiving space inside a mobile air conditioner.

Therefore, the present invention is to efficiently cool the heat generated in the condenser by supplying condensed water to the condenser. In addition, the shape of the condenser is changed to efficiently cool the heat generated in the condenser. In addition, it is intended to provide a splash fan for efficiently supplying condensed water to a condenser.

In order to solve the above problems, the present invention, the case forming the exterior, the base plate coupled to the lower part of the case, and the accommodating space provided inside the case are divided up and down into a second accommodating space and a first accommodating space. A partition plate, a condenser installed in the first accommodating space and provided as a first condensing unit and a second condensing unit, and a splash fan installed in the first accommodating space and provided as a splash impeller and a splash motor, The base plate is provided with a condensed water reservoir provided concavely on an upper surface thereof, and the splash impeller is disposed between the first condensing unit and the second condensing unit at one side of the condensed water storage unit to provide a mobile air conditioner.

Here, the first condensation unit and the second condensation unit may be spaced apart and disposed side by side, and the distance between the first condensation unit and the second condensation unit may be 14 mm to 20 mm. Alternatively, the first condensing unit may be disposed between the splash impeller and the splash motor, and a lower end of the second condensing unit may be lower than a lower end of the first condensing unit.

On the other hand, the splash impeller includes an impeller disk formed of a disk, an impeller rotation axis formed in the center of the side surface of the impeller disk, and a side wing protruding from the side surface of the impeller disk and radially disposed around the impeller rotation axis. can do. In addition, the side blades may have a curved shape in which a central portion protrudes in a direction opposite to the direction of rotation of the splash impeller.

According to the mobile air conditioner according to the present invention, the surface area of the condenser can be increased, and condensed water can be evenly supplied to the condenser, so that the condenser can be efficiently cooled. In addition, since one side of the condenser can be immersed in condensed water, the condenser can be cooled efficiently. In addition, since the amount of condensed water supplied to the condenser can be increased, the condenser can be efficiently cooled.

6 is a perspective view showing the base plate 100 of the mobile air conditioner 10 according to an embodiment of the present invention, and FIG. 7 shows a state in which the splash fan 110 is installed on the base plate 100 of FIG. 6 8 and 9 are perspective and side views of the splash impeller 112 constituting the splash fan 110 of FIG. 7 .

As shown, the base plate 100 may have a substantially rectangular shape corresponding to the shape of the cross section of the bottom portion of the accommodation space.

On the upper surface of the base plate 100, a plurality of first bottom partitioning ribs 102 are formed. The first floor partitioning rib 102 is to form a space in which condensate can flow by allowing a plurality of seals to be formed on the upper surface of the base plate 100 .

Looking more specifically, a plurality of first bottom partitioning ribs 102 are formed on the upper surface of the base plate 100, and condensate water flowing into the upper surface of the base plate 100 is formed at one end of the base plate 100. (130) can be made to flow.

The first floor partitioning rib 102 is integrally formed with the base plate 100 and may protrude upward from the upper surface of the base plate 100 .

In addition, the first floor partitioning rib 102 prevents a plurality of parts, such as the first heat exchanger 500 installed on the upper part of the base plate 100, from being in close contact with the upper surface of the base plate 100, so that the second heat exchange A predetermined space is formed so that the condensed water that is generated and dropped from the group 500 can easily flow on the upper surface of the base plate 100 .

A condensed water storage unit 104 may be provided on the upper surface of the base plate 100 and is recessed downward.

The refrigerant condensed in the first heat exchanger 500 may flow and evaporate inside the second heat exchanger 800 . When the refrigerant is evaporated, vaporization heat is absorbed by the second refrigerant pipe 810 and the second heat radiation plate 820 constituting the second heat exchanger 800 . The temperature of the second heat exchanger 800 that absorbs the heat of vaporization decreases. Since heat moves from the air passing through the second heat exchanger 800 to the second heat exchanger 800, the temperature of the air passing through the second heat exchanger 800 decreases and condensed water is generated.

The condensed water generated in the second heat exchanger 800 flows downward due to its own weight, and may flow from the second accommodating space to the first accommodating space through the partition plate 600 . The upper surface of the base plate 100 may be formed concave to collect and process the condensed water flowing downward into the condensed water storage unit 104 .

The condensed water collected in the condensed water storage unit 104 may be discharged to the outside through the condensed water outlet 130 provided at the side end of the base plate 100 .

The condensate water reservoir 104 and the condensate outlet 130 are connected to the upper surface of the base plate 100 so that the condensate collected in the condensate water reservoir 104 flows through the upper surface of the base plate 100 and flows into the condensate outlet 130. A condensate flow path 106 may be formed so as to be formed.

The condensate passage 106 may be concavely formed on the upper surface of the base plate 100 or formed by the first bottom partition rib 102 .

The base plate 100 may be formed such that the condensate passage 106 is inclined so that the condensed water flows from the condensate water reservoir 104 to the condensate outlet 130 .

As shown, a splash fan 110 composed of a splash impeller 112 and a splash motor 118 may be provided on one side of the condensed water passage 106 formed on the upper surface of the base plate 100.

The splash impeller 112 may be rotationally driven by a splash motor 118 having a rotating shaft connected to the center of the splash fan 110 . The splash impeller 112 rotates and the condensate flowing along the condensate flow path 106 may be sprayed toward the first heat exchanger 500 .

The refrigerant discharged from the compressor 202 at high temperature and high pressure may flow and be condensed in the first heat exchanger 500 . When the refrigerant is condensed, liquefaction heat is released to the first refrigerant pipe 510 and the first heat dissipation plate 52 constituting the first heat exchanger 500 . The temperature of the first heat exchanger 500 subjected to liquefaction heat is lowered. Since heat moves from the first heat exchanger 500 to the air passing through the first heat exchanger 500, the temperature of the air passing through the first heat exchanger 500 rises. Air whose temperature has increased by passing through the first heat exchanger 500 may be discharged to the outdoors through an exhaust port.

For efficient condensation of the refrigerant in the first heat exchanger 500, a first blowing unit 300 is disposed on the side of the first heat exchanger 500.

If there is liquid on the surface of the first heat exchanger 500, the liquid on the surface of the first heat exchanger 500 can absorb heat of vaporization on the surface of the first heat exchanger 500, so that the refrigerant can be more actively condensed.

The splash fan 110 is provided to spray the condensed water toward the first heat exchanger 500 so that liquid is formed on the surface of the first heat exchanger 500 .

As illustrated, the splash impeller 112 includes an impeller disk 113, an impeller so that the condensate flowing along the condensate flow path 106 by the splash fan 110 can be efficiently sprayed toward the first heat exchanger 500. It may include a rotating shaft 114 and side wings 115.

The impeller disk 113 may be provided as a circular plate. This is to facilitate rotation of the splash impeller 112 on the condensate flow path 106 side.

An impeller rotation shaft 114 that can be coupled with the rotation shaft of the splash motor 118 is provided at the center of the side surface of the impeller disk 113 .

Side blades 115 protrude from the side of the impeller disk 113 so that the condensate flowing along the condensate flow path 106 is sprayed toward the first heat exchanger 500 .

As shown, the side blades 115 are preferably arranged radially around the impeller shaft 114 so that the injection of condensed water is efficiently performed.

This is to enable the side blades 115 to pump the condensed water flowing along the condensed water passage 106 upward, so that the condensed water is efficiently sprayed toward the first heat exchanger 500.

The side blades 115 are preferably made of a curved shape protruding in the opposite direction of the rotational direction of the splash impeller 112.

When the side blades 115 are curved in the opposite direction to the direction of rotation of the splash impeller 112, the angle of entry between the side blades 115 and the condensate surface can be reduced to reduce the resistance acting on the side blades 115. . In addition, a large amount of condensed water can be pumped by the side blades 115. In addition, the condensed water pumped by the side blades 115 can be efficiently sprayed upward.

The splash impeller 112 may further include a positive part 117 penetrating the impeller disk 113 adjacent to the side blade 115 and in front of the side blade 115 based on the rotation direction. The pumping part 117 may be provided as a groove on the side of the impeller disk 113 or may be provided as a hole penetrating the side of the impeller disk 113 . The pumping unit 117 can spray a large amount of condensed water to the first heat exchanger 500 together with the side blades 115 .

The splash impeller 112 may include circumferential blades 116 protruding in the circumferential direction on the circumferential surface of the impeller disk 113. The circumferential blade 116 protrudes from the circumferential surface so that the condensed water on the circumferential surface side is sprayed in the rotational direction.

The circumferential blades 116 may be formed on the circumferential surface of the impeller disk 113 so as to be inclined in the direction of rotation of the splash impeller 112. This is to reduce the inlet angle formed by the circumferential blade 116 and the condensate surface, and to efficiently spray the condensate upward.

It is a conceptual diagram showing a state in which condensed water is supplied to the first heat exchanger 500 by the splash fan 110 of (10).

As shown, the first heat exchanger 500 of the mobile air conditioner according to an embodiment of the present invention may include a first condensing unit 550 and a second condensing unit 560. The first condensing unit 550 and the second condensing unit 560 have the first refrigerant pipe 510 connected to one so that the refrigerant can be circulated, but the first heat dissipation plate 52 can be divided into two areas. can do.

This expands the surface area of the first heat exchanger 500 and, as shown, allows the splash fan 110 to be disposed between the first heat exchangers 500, so that condensed water flows between the first heat exchangers 500. so that it can be sprayed.

13 is a conceptual diagram illustrating an installation state of the first heat exchanger 500 and the splash fan 110 of the mobile air conditioner 10 according to an embodiment of the present invention, and FIG. 14 illustrates another embodiment of FIG. 13 It is a conceptual diagram.

As shown, the first heat exchanger 500 is disposed on the side of the condensate water reservoir 104 or the condensate flow path 106, and a splash impeller ( 112) can be installed so that it can be formed.

The first condensing unit 550 and the second condensing unit 560 are spaced apart and disposed side by side, and the splash impeller 112 is formed between the spaced first condensing unit 550 and the second condensation unit 560. can

When the separation distance between the first condensing unit 550 and the second condensing unit 560 is too short, the condensed water is concentrated on the lower end of the first heat exchanger 500 because a space in which the condensed water can sufficiently reach the upper side is not formed. and can be sprayed. On the other hand, when the separation distance between the first condensing unit 550 and the second condensing unit 560 is too long, condensed water may be concentrated on the upper end of the first heat exchanger 500 .

Therefore, it is preferable that the separation distance between the first condensing unit 550 and the second condensing unit 560 is 14 mm to 20 mm.

This is to provide a space in which the splash impeller 112 can be formed between the first condensing unit 550 and the second condensing unit 560 . It is preferable to maintain a distance of 3 mm to 5 mm between both sides of the splash impeller 112 and the first and second condensing units 550 and 560, respectively. This is to provide a space where the condensed water sprayed upward by the rotation of the splash impeller 112 can reach the lower and upper sides of the first heat exchanger 500 evenly.

In the first heat exchanger 500 , the first condensing unit 550 and the second condensing unit 560 may have different heights.

In the splash impeller 112, the impeller rotation shaft 114 formed in the center of the side surface is coupled to the rotation shaft of the splash motor 118. Since the separation distance between the first condensing unit 550 and the second condensing unit 560 is narrow for the splash motor 118 to be installed, the splash motor 118 is disposed outside the first heat exchanger 500 and This is so that the lower end of the first condensing unit 550 is located above the part where the rotation shaft of the impeller rotation shaft 114 and the rotation shaft of the splash motor 118 are coupled.

At this time, it is preferable that the distance between the lower end of the second condensing unit 560 and the upper surface of the condensing water storage unit 104 is formed within 30 mm. Of course, the lower end of the second condensing unit 560 may contact the upper surface of the base plate 100 . Then, the lower end of the second condensing unit 560 may be disposed to be submerged in the condensed water.

When the lower end of the second condensing unit 560 is submerged in the condensed water, since heat is directly transferred to the condensed water, the first heat exchanger 500 can be easily cooled.

In the partition plate 600, a plurality of bottom condensate holes 604 are vertically formed through. The bottom condensate hole 604 allows the condensed water generated in the second heat exchanger 800 and falling to move to the lower side of the partition plate 600 .

A condensate falling guide (not shown) may be further formed on the lower surface of the partition plate 600 . The condensate falling guide is for allowing the condensed water moving to the lower surface of the partition plate 600 to directly fall smoothly through the bottom condensate hole 604 .

That is, the condensed water falling guide serves to induce the condensed water moved to the lower surface of the partition plate 600 to fall directly without flowing to other parts.

Therefore, the condensate falling guide protrudes downward from the lower surface of the partition plate 600 . More specifically, the condensate falling guide is formed extending downward from each bottom condensate hole 604 . The condensate falling guide extends downward from the bottom condensate hole 604 and may have a cylindrical shape corresponding to the bottom condensate hole 604 .

A centrifugal blower is a blower that generates air volume and pressure while moving air in the radial direction of the impeller, and can flow a large volume of air at a low pressure. In addition, since the diameter of the impeller can be formed small, the installation space can be minimized, and thus the mobile air conditioner 10 can be miniaturized.

A second blowing unit 700 may be installed on the upper surface of the partition plate 600 . The second blowing unit 700 includes a second blowing housing 720 provided with a second blowing guide 721 and a second blowing orifice 722, a second blowing motor 730, and a second impeller 740.

Considering that the discharge port 1044 through which the air-conditioned air is discharged into the room is formed on the upper part of the mobile air conditioner 10, the mobile air conditioner 10 can secure a sufficient discharge area of the discharge port 1044. It may be formed long from the top to the side. Accordingly, the blowing nozzle 726 is used to discharge completely air-conditioned air from the second tuyere 725 to the discharge port 1044 between the second blowing unit 724 and the discharge unit 1041 .

The second blower 724 is a place where the air introduced into the second accommodating space is discharged, and the second blower grill 710 prevents small-sized foreign substances such as dust from entering the second blower 725. Rather, it is installed to prevent foreign matter from entering through the second tuyere 725 and damaging the second impeller 740 .

Therefore, it is preferable that the second air outlet grill 710 is formed to prevent foreign matter from being introduced through the second air outlet 725, but not to prevent air from being discharged through the second air outlet 725.

21 is a conceptual diagram showing a state in which air flows inside the mobile air conditioner 10 according to an embodiment of the present invention.

Hereinafter, with reference to FIG. 21, the operation of the mobile air conditioner 10 according to the present invention as described above will be described.

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

The mobile air conditioner 10 according to the present invention can be used for cooling or heating, but as described above, a case in which the mobile air conditioner 10 according to the present invention is used for cooling will be described as an example.

At this time, the first heat exchanger 500 serves as a condenser and the second heat exchanger 800 serves as an evaporator. A refrigerant pipe 400 is connected between the compressor 202 and 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 and becomes a high-temperature, high-pressure state and flows into the first heat exchanger 500, the refrigerant is condensed in the first heat exchanger 500 by heat exchange with outside air.

Then, the condensed refrigerant is expanded while passing through an expansion valve (not shown), and introduced into the second heat exchanger (800).

The refrigerant introduced into the second heat exchanger 800 evaporates through heat exchange with external air. Therefore, the refrigerant is in a gaseous state, but at this time, the refrigerant in a liquid state also remains, so that the two-phase refrigerant actually coexists.

After passing through the accumulator 203, the refrigerant flows back to the compressor 202 to complete a refrigerant cycle.

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

First, air flow (indicated by a black arrow in the drawing) in the heat radiation side (first accommodating space) will be examined. Air flow at this time is basically generated by the first impeller 340 .

That is, when the first blower motor 330 is driven by power 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.

Accordingly, air from the rear may be introduced through the first inlet 1130 formed at the bottom of the rear case 1100 . The air introduced through the first inlet 1130 changes direction and flows in a sideward direction, and passes through the first heat exchanger 500 .

The temperature of the air passing through the first heat exchanger 500 rises. That is, since the first heat exchanger 500 serves as a condenser, heat is transferred from the refrigerant flowing inside the first heat exchanger 500 and the air is in a high temperature state.

The high-temperature air passing through the first heat exchanger 500 passes through the first blowing orifice 323 and is introduced into the center of the first impeller 340 . The air introduced into the central part of the first impeller 340 flows radially by the rotation of the first impeller 340 and is guided inside the first blowing guide 322 and the first blowing orifice 323 and discharged upward.

The high-temperature air guided inside 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 part 1300 .

Next, a flow of air (indicated by a white arrow in the drawing) occurring in the heat absorbing side (second receiving space) will be 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 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, outside air is introduced into the first accommodation space through the second inlet 1110 formed on the upper part of the rear case 1100 . The air introduced through the second intake port 1110 passes through the second intake grill 1120 and a filter installed on the side of the second intake port 1110, and in this process, foreign substances or odors in the air can be removed.

The air introduced into the second accommodating 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 is introduced into the center of the second impeller 740 . The air introduced into the center of the second impeller 740 is radially discharged by the rotation of the second impeller 740, and this air is guided inside the second blowing guide 721 and the second blowing orifice 722 to the upper side. will flow with

The air guided inside the second blowing guide 721 and the second blowing orifice 722 and flowing upward passes through the second outlet 725 and the discharge louver 750 . The low-temperature air passing through the discharge louver 750 can be diverted and discharged, so that the indoor space can be smoothly cooled.

Next, condensate flow is examined.

In the second heat exchanger 800, heat exchange occurs between external air and internal refrigerant, and in this process, moisture in the air is condensed 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 . Condensate falling on the upper surface of the partition plate 600 is guided by the second bottom partition rib 602 and flows, and in this process moves downward through the partition plate 600 through the bottom condensate hole 604. do.

The condensate that has passed through the bottom condensate hole 604 and moved to the lower side of the partition plate 600 picks up the inner surface of the condensate drop guide and flows down, forms on the lower end of the condensate drop guide, and then falls downward.

The condensed water that has fallen downward may flow into the upper surface of the base plate 100 . The condensed water flowing into the upper surface of the base plate 100 may flow toward the condensate outlet 130 provided at one end of the base plate 100 along the condensed water passage 106 formed on the upper surface of the base plate 100.

When the condensate flows toward the condensate outlet 130, it may be discharged to the outside of the mobile air conditioner 10 through the condensate outlet 130.
