Hereinafter, a detailed configuration of the portable air conditioner 1 according to an embodiment of the present invention will be described with reference to the drawings.

Hereinafter, referring to FIGS. 1 to 3 , the portable air conditioner 1 according to an embodiment of the present invention may provide cool air to a user by cooling hot external air. In addition, the portable air conditioner 1 may provide warm air to the user by heating cold outside air. The portable air conditioner 1 may be configured to be portable and provide convenience to a user. The portable air conditioner 1 may include a case 100 , a compressor 200 , a condenser 300 , an evaporator 400 , a heater 500 , a filter 600 , and fan modules 700 and 800 .

The case 100 may accommodate the compressor 200 , the condenser 300 , the evaporator 400 , the heater 500 , the filter 600 , and the fan modules 700 and 800 . The case 100 may be provided with a handle (not shown) to be gripped by the user. In addition, an inlet 110 and an outlet 120 may be formed in the case 100 .

The inlet 110 may be formed in the case 100 so that external air can be introduced into the case 100 . Hereinafter, the air outside the case 100 is referred to as outside air. For example, the inlet 110 may be formed in the center of the case 100 . In addition, a filter 600 may be disposed at the inlet 110 , and external air may flow into the case 100 through the filter 600 .

The discharge port 120 may be formed in the case 100 so that the internal air flowing inside the case 100 can be discharged to the outside of the case 100 . Hereinafter, the air inside the case 100 is called internal air. The outlet 120 may include a first outlet 121 and a second outlet 122 .

The first outlet 121 may be formed in the case 100 so that internal air cooled to a predetermined temperature or heated through the evaporator 400 may be discharged. Hereinafter, internal air cooled to a predetermined temperature by heat exchange with the evaporator 400 is called cooling air, and internal air heated by the heater 500 and heated to a predetermined temperature is called heating air. Also, the first outlet 121 may be formed on one side (eg, the right side of FIG. 3 ) of the case 100 in the axial direction c.

The second discharge port 122 may be formed in the case 100 so that internal air raised to a predetermined temperature through the condenser 300 may be discharged. Hereinafter, the internal air raised to a predetermined temperature by heat exchange with the condenser 300 is referred to as high-temperature air. In addition, the second discharge port 122 may be formed on the other side (eg, the left side of FIG. 3 ) of the case 100 in the axial direction (c).

The compressor 200 may compress the refrigerant to a predetermined pressure.

The condenser 300 may condense the refrigerant compressed in the compressor 200 . For example, the condenser 300 may liquefy the refrigerant by heat exchange with the internal air. In this case, the internal air may rise to a predetermined temperature through heat exchange with the condenser 300 .

The evaporator 400 may evaporate the refrigerant. For example, the evaporator 400 may vaporize the refrigerant by heat exchange with the internal air. In this case, the internal air may be cooled to a predetermined temperature through heat exchange with the evaporator 400 .

The heater 500 may heat the internal air to a predetermined temperature. For example, the heater 500 may be a positive temperature coefficient heater (PTC). The heater 500 may be disposed between the evaporator 400 and the fan unit 700 in the axial direction c.

The filter 600 may filter outside air. The filter 600 may be disposed at the inlet 110 to filter the air passing through the inlet 110 . In addition, external air passing through the filter 600 may flow into the case 100 .

The fan modules 700 and 800 may include a fan unit 700 and a guide 800 .

Referring back to FIG. 3 , the fan unit 700 may provide a blowing force for flowing the internal air to the outlet 120 . Also, the fan unit 700 may rotate about a predetermined rotation axis. Here, the rotation shaft of the fan unit 700 may extend along the axial direction (c). The fan unit 700 may include a first fan unit 710 and a second fan unit 720 .

The first fan unit 710 may provide a blowing force for flowing the internal air that has passed through the evaporator 400 to the first outlet 121 . That is, the first fan unit 710 may flow the cooling air to the first outlet 121 . In addition, the first fan unit 710 may flow the heated air to the first outlet 121 . The first fan unit 710 may be disposed adjacent to the first outlet 121 , and may be disposed between the heater 500 and the guide 800 in the axial direction c.

The second fan unit 720 may provide a blowing force for flowing the internal air that has passed through the condenser 300 to the second outlet 122 . That is, the second fan unit 720 may flow the high-temperature air to the second outlet 122 . The second fan unit 720 may be disposed adjacent to the second outlet 122 .

Meanwhile, the first fan unit 710 and the second fan unit 720 may include a fan housing 711 and a fan 712 .

The fan housing 711 may support the fan 712 , and may be provided to surround at least a portion of the fan 712 . For example, both sides of the fan housing 711 may be opened in the axial direction c. In addition, the fan housing 711 may have a predetermined length in the axial direction (c).

The fan 712 may rotate about a rotating shaft, and may provide blowing force for flowing internal air. The fan 712 may include a plurality of blades.

4 to 6 , the guide 800 may guide the internal air that has passed through the fan unit 700 to the outlet 120 . In addition, the guide 800 may guide the flow of the internal air so that the internal air flowing by the fan unit 700 flows along the axial direction (c). The guide 800 may include a body portion 810 , a tapered portion 820 , a first wall portion 830 , a second wall portion 840 , and a grill portion 850 .

The body part 810 may support the tapered part 820 and the grill part 850 . The body portion 810 may have a predetermined length in the axial direction (c), and the central portion may be opened. In addition, the body portion 810 may extend to have a predetermined loop shape when viewed in the axial direction (c). For example, the body portion 810 may have a ring shape. In this case, the body portion 810 may extend in a rotational direction about the rotation axis. Here, the loop shape may be a shape returning to one point from one point through another point.

On the other hand, when the body portion 810 is arranged so that the center is placed on the rotation axis, the distance from the center to the body portion 810 in the direction perpendicular to the axial direction c is one end from the center of the fan 712 . It may be configured to be shorter than the distance to That is, the radius of the opening formed in the body portion 810 may be smaller than the radius of the fan 712 . For this reason, when viewed in the axial direction c, one end of the fan 712 may not be exposed by the body 810 .

The tapered part 820 may guide the flow of the internal air so that the internal air that has passed through the first fan unit 710 passes through the inside of the body part 810 . The tapered portion 820 may have a predetermined loop shape when viewed in the axial direction (c). In addition, one end of the tapered portion 820 in the axial direction (c) may be connected to the body portion 810 , and at least a portion of the other end may be connected to the first wall portion 830 . The tapered portion 820 may extend in a direction shifting with respect to the axial direction c, and the other end of the axial direction c may extend in a direction away from the rotation axis.

As such, since the tapered portion 820 is extended to be inclined rather than perpendicular to the axial direction c, the internal air flowing toward the tapered portion 820 may form a laminar flow without forming a turbulence. In addition, the internal air that has passed through the first fan unit 710 may be concentrated toward the center of the body portion 810 . For this reason, the internal air passing through the body portion 810 can flow along the axial direction (c) while being more dense, and there is an effect that the straightness can be maintained.

Meanwhile, at least a portion of the tapered portion 820 may contact the fan housing 711 to prevent internal air from flowing between the tapered portion 820 and the fan housing 711 . For example, a portion adjacent to the other end of the tapered portion 820 in the axial direction c may contact the fan housing 711 .

As such, the tapered portion 820 is provided to be in contact with the fan housing 711 , so that the amount of internal air leaked between the fan housing 711 and the tapered portion 820 can be minimized. That is, cooling air or heating air has the effect of being provided to the user by minimizing the flow rate loss.

The first wall portion 830 may be provided to surround the body portion 810 and the tapered portion 820 . In addition, when viewed in the axial direction (c), the first wall portion 830 may extend to have a predetermined loop shape. For example, the first wall portion 830 may have a rectangular ring shape surrounding the body portion 810 and the tapered portion 820 outside the axial direction (c). The first wall portion 830 may have a predetermined length in the axial direction c, and the length of the first wall portion 830 in the axial direction c may be longer than that of the tapered portion 820 .

The second wall part 840 may seal between the tapered part 820 and the first wall part 830 to prevent internal air from flowing between the tapered part 820 and the first wall part 830 . The second wall portion 840 may extend on a virtual plane perpendicular to the axial direction c, and may be connected to the tapered portion 820 and the first wall portion 830 .

As such, it is possible to block the internal air flowing between the first wall portion 830 and the tapered portion 820 by the first wall portion 830 and the second wall portion 840, thereby preventing the formation of turbulence. It works.

The grill part 850 is supported by the body part 810 , and may cover at least a portion of an open portion of the body part 810 .

Meanwhile, the portable air conditioner 1 may further include a controller (not shown) capable of controlling the operations of the compressor 200 , the condenser 300 , the evaporator 400 , the heater 500 , and the fan unit 700 . have. The control unit includes the compressor 200, the condenser 300, the evaporator 400, and the portable air conditioner 1 so that the portable air conditioner 1 is switched from one state to another in a cooling state in which cooling air is discharged and a heating state in which heated air is discharged. It is possible to control the operation of the heater 500 and the fan unit 700 . For example, when the portable air conditioner 1 is placed in a cooling state, the controller may drive the compressor 200 , the condenser 300 , and the evaporator 400 , but may not drive the heater 500 . As another example, when the portable air conditioner 1 is placed in a heating state, the controller may drive the heater 500 without driving the compressor 200 , the condenser 300 , and the evaporator 400 . Such a control unit may be implemented by an arithmetic device including a microprocessor, a measuring device such as a sensor, and a memory, and the implementation method is obvious to those skilled in the art, so a detailed description thereof will be omitted.

Hereinafter, the operation and effect of the portable air conditioner 1 having the above-described configuration will be described.

When the portable air conditioner 1 is placed in a cooling state, the compressor 200 , the condenser 300 , the evaporator 400 , and the fan unit 700 may be driven. In this case, after the outside air is filtered while passing through the filter 600 , a part may flow to the condenser 300 and the other part may flow to the evaporator 400 . The high-temperature air passing through the condenser 300 may flow to the first outlet 121 by the second fan unit 720 . Also, the cooling air passing through the evaporator 400 may flow to the guide 800 by the first fan unit 710 . The cooling air introduced into the guide 800 may be concentrated in the center of the body portion 810 by the tapered portion 820 , and may flow along the axial direction c through the body portion 810 . Such cooling air may be provided to the user through the first outlet 121 .

In addition, when the portable air conditioner 1 is placed in a heating state, the heater 500 and the fan unit 700 may be driven. In this case, the outside air may flow to the heater 500 through the filter 600 . In addition, the heated air that has passed through the heater 500 may be provided to the user through the first outlet 121 .

As such, since the tapered portion 820 is extended to be inclined rather than perpendicular to the axial direction c, the internal air flowing toward the tapered portion 820 may form a laminar flow without forming a turbulence. In addition, the internal air introduced between the first wall part 830 and the tapered part 820 may be blocked by the first wall part 830 and the second wall part 840 . For this reason, there is an effect that the internal air passing through the guide 800 can form a laminar flow without forming a turbulent flow. In addition, the directness of the internal air is maintained to provide a higher cooling or heating effect to the user.

Meanwhile, since the tapered portion 820 is provided to be in contact with the fan housing 711 , the amount of internal air leaking between the fan housing 711 and the tapered portion 820 can be minimized, and discharged through the first outlet 121 . flow can be maximized. In addition, the tapered portion 820 is disposed to be inclined with respect to the axial direction (c), so that the internal air passing through the first fan unit 710 may be more densely packed inside the body portion 810 . Due to this, a higher flow rate of air may be densely provided to the user, and a higher cooling or heating effect may be provided to the user.

Although the embodiments of the present invention have been described as specific embodiments, these are merely examples, and the present invention is not limited thereto, and should be interpreted as having the widest scope according to the technical idea disclosed in the present specification. A person skilled in the art may implement a pattern of a shape not specified by combining/substituting the disclosed embodiments, but this also does not depart from the scope of the present invention. In addition, those skilled in the art can easily change or modify the disclosed embodiments based on the present specification, and it is clear that such changes or modifications also fall within the scope of the present invention.
