Description

Air conditioner

Technical Field

Embodiments of the present disclosure relate to an air conditioner, and more particularly, to an air conditioner using an improved air discharge method.

Background

Generally, an air conditioner is a device that adjusts temperature, humidity, air flow, distribution, etc. to conditions suitable for human activities using a refrigeration cycle. The air conditioner includes a compressor, a condenser, an evaporator, a fan, etc., as main components constituting a refrigeration cycle.

Air conditioners may be classified into a split type air conditioner in which an indoor unit and an outdoor unit are separately installed, and a window type air conditioner in which an indoor unit and an outdoor unit are installed together in a single cabinet. An indoor unit of a split type air conditioner includes: a heat exchanger that exchanges heat with air drawn into the panel; and a fan which sucks indoor air into the panel and discharges the sucked air to the indoor space again. The indoor unit of the conventional air conditioner has been manufactured to miniaturize the heat exchanger and raise the RPM of the fan so as to maximize the wind speed and the air flow. Accordingly, the discharge temperature is lowered, and the discharged air forms a narrow, long flow path to be discharged to the indoor space.

When the user is directly exposed to the discharged air, the user may feel cold and unpleasant. On the other hand, when the user is not exposed to the discharged air, the user may feel hot and unpleasant.

In addition, if the user increases the RPM of the fan to raise the wind speed, noise increases. In addition, the radiant air conditioner that does not use a fan to condition air requires a large panel to achieve the same performance as the air conditioner that uses a fan. In addition, the radiation air conditioner has a very low cooling rate and requires high construction costs.

Hereinafter, for convenience of description, an indoor unit including an indoor heat exchanger will be referred to as an air conditioner, and an indoor heat exchanger will be referred to as a heat exchanger.

Fig. 1 and 2 are perspective views of an air conditioner according to an embodiment of the present disclosure. Fig. 3 and 4 are views describing the operation of the air conditioner according to the embodiment of the present disclosure.

Referring to fig. 1 to 4, the air conditioner 1 may include a case 10, a heat exchanger 20, and a fan 30, wherein the case 10 has an inlet 12 and an outlet 14; the heat exchanger 20 exchanges heat with air entering the casing 10; the fan 30 circulates air inside or outside the case 10.

The housing 10 may have a substantially circular cross-section and may have a generally cylindrical shape. However, the shape of the housing 10 is not limited thereto.

The housing 10 may include vanes 16 that direct air blown out through the outlet 14. Vanes 16 may be located on the outlet 14 to control the direction of air blowing out through the outlet 14, and may block the outlet 14 to close the outlet 14. More specifically, the blade 16 is rotatable between a guide position in which the blade 16 is disposed in a direction parallel to the air blowing direction and a closed position; in the closed position the blades 16 block the blowing out of air.

The fan 30 may be a cross-flow fan, although not limited thereto. In the current embodiment, the housing 10 and the outlet 14 may extend in a vertical direction as an axial direction, and the fan 30 as a cross flow fan may extend in a vertical direction within the housing 10.

The heat exchanger 20 may be disposed inside the case 10 to perform heat exchange with air entering through the inlet 12. In other words, the heat exchanger 20 may absorb or transfer heat from air entering via the inlet 12. Below the heat exchanger 20, a drain panel (not shown) may be provided to collect water condensed in the heat exchanger 20.

The air conditioner 1 may include a flow path guide 40. A flow path guide 40 may be formed between the fan 30 and the outlet 14 to guide the flow of air. The outlet 14 may be located at one end of the flow path guide 40.

The air conditioner 1 may include a door 50. The door 50 may open or close the outlet 14 of the housing 10. The door 50 is movable between a first position 50a and a second position 50b, wherein in the first position 50a the door 50 opens the outlet 14; in the second position 50b the door 50 closes the outlet 14. In the current embodiment, the door 50 is slidable between the first position 50a and the second position 50b, although the operation of the door 50 is not limited thereto.

Since the housing 10 has a substantially cylindrical shape, the door 50 may also be curved. More specifically, the front surface of the case 10 may be at least partially curved, and the door 50 may also be curved to correspond to the curved front surface of the case 10.

The door 50 may include a door body 52 and a plurality of apertures 54 formed in the door body 52. As described above, the door body 52 may be curved to cover the outlet 14. A plurality of apertures 54 may be formed in at least a portion of the door body 52. In the current embodiment, the plurality of holes 54 may be formed in the entire region of the door body 52. The plurality of holes 54 may discharge air to the outside of the case 10 even when the door 50 is in the second position 50 b.

The door 50 may discharge the heat-exchanged air flowing to the outlet 14 to the outside of the case 10 through a plurality of holes 54. Thereby, it is possible to condition the indoor space with the air conditioner without directly transferring the heat-exchanged air to the user.

Hereinafter, the operation of the air conditioner according to the above-described configuration will be described.

First, an operation in which air blown by the fan 30 is discharged to the outside of the casing 10 through the outlet 14 will be described.

Referring to fig. 1 and 3, the door 50 may be in a first position 50a where it opens the outlet 14. The air entering the inside of the case 10 through the inlet 12 may exchange heat with the heat exchanger 20 and then pass through the fan 30. The heat-exchanged air blown by the fan 30 may be guided by the flow path guide 40 and thus discharged to the outside of the case 10 through the outlet 14.

In this case, since the air conditioner 1 blows the heat-exchanged air to the outside of the case 10 through the outlet 14, the air conditioner 1 can adjust the indoor temperature more rapidly than in the case where the heat-exchanged air is blown out through a plurality of holes.

Next, an operation in which air blown by the fan 30 is discharged to the outside of the case 10 through the plurality of holes 54 of the door 50 will be described.

Referring to fig. 2 and 4, the door 50 may be in a second position 50b where it closes the outlet 14. The air entering the inside of the case 10 through the inlet 12 may exchange heat with the heat exchanger 20 and then pass through the fan 30. The heat-exchanged air blown by the fan 30 may be guided by the flow path guide 40 and thus discharged to the outside of the case 10 through the plurality of holes 54 formed in the door 50.

In this case, since the air conditioner 1 blows the heat-exchanged air to the outside of the casing 10 through the plurality of holes 54 of the discharge plate, the blown air may not be directly transferred to the user, thereby improving the satisfaction of the user.

Hereinafter, an air conditioner according to another embodiment of the present disclosure will be described. Hereinafter, description about the same configuration as the above-described configuration will be omitted.

The air conditioner 600 may include a flow path guide 640. A flow path guide 640 may be formed between the fan 30 and the outlet 414 to guide the flow of air. The outlet 414 may be located at one end of the flow path guide 640. The outlet 414 may be located at an end of the flow path guide 640.

The flow path guide 640 may include a fixed guide 642 and a variable guide 644, wherein the variable guide 644 is rotatably formed at one end of the fixed guide 642 to increase the width of the flow path.

The flow path guide 640 moves between a first position 640a and a second position 640b, wherein in the first position 640a the flow path guide 640 forms a first flow path to direct air to the outlet 414; in the second position 640b the flow path guide 640 forms a second flow path wider than the first flow path by moving from the first position 640a to guide air to the discharge plate 460.

More specifically, the flow path guide 640 is movable between a first position 640a and a second position 640b, where in the first position 640a the variable guide 644 directs air blown by the fan 30 to the outlet 414; in the second position 640b, the variable guide 644 moves from the first position 640a to widen the flow path and guide the air to the discharge plate 460. When the outlet is closed, the variable guide 644 may move to discharge air to the discharge plate 460. Air may also be discharged through the plurality of holes 418 of the blade 416 when the flow path guide 640 is in the second position 640 b.

Referring to fig. 16, the vanes 416 may be in a pilot position 416a where the vanes 416 open the outlet 414. The air entering the inside of the case 10 through the inlet 12 may exchange heat with the heat exchanger 20 and then pass through the fan 30. The heat-exchanged air blown out via the fan 30 may be guided by the flow path guide 640 to be discharged to the outside of the case 10 through the outlet 14.

Next, an operation in which the air blown by the fan 30 is discharged to the outside of the casing 10 through a plurality of holes will be described.

Referring to fig. 17, the vanes 416 may be in a closed position 416b, where the vanes 416 close the outlet 414. The air entering the inside of the case 10 through the inlet 12 may exchange heat with the heat exchanger 20 and then pass through the fan 30. At this time, the flow path guide 640 may be located at the second position 640b such that the width of the flow path is wider than when the flow path guide 640 is at the first position 640 a. Since the outlet 414 is closed by the vane 416, the heat-exchanged air blown out via the fan 30 may be discharged to the outside through the plurality of holes 462 of the discharge plate 460 and/or the plurality of holes 418 of the vane 416 along the flow path widened by the variable guide 644.

Fig. 19 and 20 are views for describing the operation of an air conditioner according to another embodiment of the present disclosure.

Referring to fig. 19 and 20, the air conditioner 700 may include a flow path guide 740. A flow path guide 740 may be formed between the fan 30 and the outlet 414 to guide the flow of air. The outlet 414 may be located at one end of the flow path guide 740. The outlet 414 may be located at an end of the flow path guide 740.

The flow path guide 740 may be variable. In other words, the flow path guide 740 is movable between a first position 740a and a second position 740b, wherein in the first position 740a the flow path guide 740 directs air blown by the fan 30 to the outlet 414; in the second position 740b the flow path guide 740 directs air to the outlet 414 and the discharge plate 460 by moving from the first position 740a to enlarge the width of the flow path. An end of the flow path guide 740 may correspond to the outlet 414 in the first position 740a and may correspond to an end of the drain plate 460 in the second position 740 b.

The air conditioner according to the present disclosure may discharge heat-exchanged air at different wind speeds.

In addition, the air conditioner according to the present disclosure may change a method of blowing out the heat-exchanged air according to the environment of the user.

In addition, the air conditioner according to the present disclosure may adjust the heat-exchanged air so as not to be directly blown to the user to thereby improve the satisfaction of the user.

The present disclosure has been described in detail with reference to exemplary embodiments. However, the exemplary embodiments should be considered in a descriptive sense only and the disclosure is not limited thereto. It will be apparent to those skilled in the art that various modifications and improvements can be made which are within the scope of the disclosure.
