[0140] As illustrated in FIGS. 5 to 10, the nozzle device (100) can be attached to the drying cover (200). The nozzle device (100) can be attached to the drying cover (200) in an up-and-down direction. The nozzle device (100) can be attached to the drying cover (200) at the top of the drying cover (200). Since the nozzle device (100) is attached to the drying cover (200) at the top of the drying cover (200), when the nozzle device (100) is attached to the drying cover (200), the gap between the nozzle device (100) and the heat exchangers (92, 93) can be minimized / reduced.

[0141] When the nozzle device (100) is attached to the drying cover (200) so as to slide horizontally, the nozzle device (100) may tilt and come into contact with the heat exchanger (92, 93) located at the bottom of the drying cover (200) during the attachment process. If the nozzle device (100) comes into contact with the heat exchanger (92, 93), damage may occur to the heat exchanger (92, 93). Therefore, if the nozzle device (100) is attached to the drying cover (200) in an up-and-down direction, damage to the heat exchanger (92, 93) can be prevented / reduced, and the gap between the nozzle device (100) and the heat exchanger (92, 93) can be minimized / reduced.

[0142] Since the nozzle device (100) is connected to the drying cover (200) in an up-and-down direction so that the gap between the nozzle device (100) and the heat exchanger (92, 93) can be minimized / reduced, the area of ​​the heat exchanger (92, 93) that is not cleaned can be minimized / reduced even when the water pressure of the cleaning water supplied to the nozzle device (100) is high and the cleaning water is sprayed in a diagonal direction. Since the nozzle device (100) is connected to the drying cover (200) in an up-and-down direction so that the gap between the nozzle device (100) and the heat exchanger (92, 93) can be minimized / reduced, the area of ​​the heat exchanger (92, 93) that is not cleaned can be minimized / reduced even when the water pressure of the cleaning water supplied to the nozzle device (100) is low and the cleaning water clumps together.

[0143] The drying cover (200) can cover the upper part of the heat exchanger (92, 93). The nozzle device (100) attached to the drying cover (200) can spray cleaning water onto the heat exchanger (92, 93). The heat exchanger (92, 93) can be cleaned by the cleaning water sprayed from the nozzle device (100).

[0144] The nozzle device (100) may include a nozzle (110). The nozzle (110) may be seated in a lower nozzle case (140). The nozzle (110) may include a plurality of nozzle holes (111). Cleaning water supplied to the nozzle device (100) may be supplied to the nozzle (110). Cleaning water supplied to the nozzle (110) may be sprayed into the heat exchanger (92, 93) through the plurality of nozzle holes (111). The heat exchanger (92, 93) may be cleaned by the cleaning water sprayed from the plurality of nozzle holes (111).

[0145] The nozzle device (100) may include a sealing member (120) including a seal. The sealing member (120) may be provided to surround the edge of the nozzle (110). The sealing member (120) may be assembled to the edge of the nozzle (110). The sealing member (120) may be assembled to the edge of the nozzle (110) to surround the edge of the nozzle (110). By the sealing member (120) surrounding the edge of the nozzle (110), leakage of cleaning water supplied to the nozzle (110) can be prevented / reduced.

[0146] Since the sealing member (120) is assembled to the edge of the nozzle (110) so as to surround only the nozzle (110), the sealing member (120) can be easily assembled. Additionally, since the nozzle (110) is seated in the upper and lower direction on the lower nozzle case (140) after the sealing member (120) is assembled to the edge of the nozzle (110) so as to surround the nozzle (110), the sealing member (120) assembled on the nozzle (110) can be easily seated on the lower nozzle case (140).

[0147] The sealing member (120) may include a sealing portion (121) provided to surround the edge of the nozzle (110).

[0149] The first discharge hole (123) can be configured so that when the water pressure of the cleaning water supplied to the multiple nozzle holes (111) is high, some of the supplied cleaning water is not supplied to the multiple nozzle holes (111) but is discharged directly to the heat exchanger (92, 93). When the water pressure of the cleaning water supplied to the multiple nozzle holes (111) is high, the cleaning water sprayed into the multiple nozzle holes (111) may not fall vertically toward the heat exchanger (92, 93) but may fall diagonally. When the cleaning water sprayed into the multiple nozzle holes (111) falls diagonally, a problem may occur in which cleaning water does not fall into a part of the heat exchanger (92, 93) and therefore is not cleaned. When the pressure of the washing water supplied to the multiple nozzle holes (111) is high, if a portion of the washing water is discharged to the heat exchanger (92, 93) through the first discharge hole (123), the pressure of the washing water is lowered, and the washing water sprayed through the multiple nozzle holes (111) can fall vertically toward the heat exchanger (92, 93).

The second case assembly hole (143) may be formed at a position corresponding to the first case assembly hole (137) formed in the upper nozzle case (130). The upper nozzle case (130) may be assembled to the second case assembly hole (143) of the lower nozzle case (140). The lower nozzle case (140) may be assembled to the upper nozzle case (130) by an assembly member (S) that is assembled to the second case assembly hole (143) formed in the lower nozzle case (140) and the first case assembly hole (137) formed in the upper nozzle case (130).

[0159] The lower nozzle case (140) may include a second discharge hole (145). The second discharge hole (145) may be formed at a position corresponding to the first discharge hole (123) formed in the sealing member (120). At least one second discharge hole (145) may be formed in the lower nozzle case (140). Although the drawing shows only one second discharge hole (145) formed in the lower nozzle case (140), it is not limited thereto.

[0160] The second discharge hole (145) may be formed at a position corresponding to one of the pair of first discharge holes (123) formed in the sealing member (120). When the water pressure of the cleaning water supplied to the plurality of nozzle holes (111) is high, some of the supplied cleaning water may not be supplied to the plurality of nozzle holes (111) and may be discharged to the heat exchanger (92, 93) through the first discharge hole (123) of the sealing member (120) and the second discharge hole (145) of the lower nozzle case (140). That is, the cleaning water discharged through the first discharge hole (123) of the sealing member (120) may be discharged to the heat exchanger (92, 93) through the second discharge hole (145) of the lower nozzle case (140).

[0161] When the water pressure of the cleaning water supplied to the multiple nozzle holes (111) is high, the cleaning water sprayed through the multiple nozzle holes (111) may fall diagonally rather than vertically toward the heat exchanger (92, 93). When the cleaning water sprayed through the multiple nozzle holes (111) falls diagonally, a problem may occur where the cleaning water does not fall on a part of the heat exchanger (92, 93) and thus is not cleaned. When the water pressure of the cleaning water supplied to the multiple nozzle holes (111) is high, if a portion of the cleaning water is discharged to the heat exchanger (92, 93) through the first discharge hole (123) and the second discharge hole (145), the water pressure of the cleaning water decreases, and the cleaning water sprayed through the multiple nozzle holes (111) may fall vertically toward the heat exchanger (92, 93).

[0162] The nozzle device (100) may include a leak prevention rib (150). The leak prevention rib (150) may be provided to extend downward from the upper wall of the upper nozzle case (130). The leak prevention rib (150) may be formed in a square shape. A lower nozzle case (140) may be accommodated inside the leak prevention rib (150) having a square shape. That is, when the lower nozzle case (140) is assembled to the upper nozzle case (130), the lower nozzle case (140) may be accommodated inside the leak prevention rib (150).

[0163] Since the lower nozzle case (140) is housed inside the leak prevention rib (150), the cleaning water supplied to the nozzle (110) seated in the lower nozzle case (140) and sprayed into the plurality of nozzle holes (111) can be prevented / blocked from leaking outside the upper nozzle case (130) by the leak prevention rib (150). Although the cleaning water supplied to the nozzle (110) seated in the lower nozzle case (140) and sprayed into the plurality of nozzle holes (111) can be prevented / blocked from leaking by the sealing member (120), even if the sealing member (120) is broken, the leakage of cleaning water can be prevented / reduced by the leak prevention rib (150) in a double manner. For example, the cleaning water supplied to the nozzle device (100) and sprayed into the plurality of nozzle holes (111) can be prevented / blocked from leaking outside the nozzle device (100) by the sealing member (120) in the first step, and can be prevented / blocked from leaking outside the nozzle device (100) in the second step by the leak prevention rib (150).

[0164] Since the lower nozzle case (140) is accommodated inside the leak-prevention rib (150), the leak-prevention rib (150) may be positioned between the receiving hole (205) of the drying cover (200) and the lower nozzle case (140). The leak-prevention rib (150) may be provided to extend to a position corresponding to the bottom of the lower nozzle case (140) accommodated inside the leak-prevention rib (150). (e.g., see FIG. 12)

[0165] A nozzle device (100) can be attached to a drying cover (200) that covers the upper part of a heat exchanger (92, 93). The drying cover (200) may include an assembly hole (201). The assembly hole (201) may be formed adjacent to the edge of a receiving hole (205). One end of an upper nozzle case (130) may be fitted into the assembly hole (201) and assembled. An assembly projection (131) formed on one end of the upper nozzle case (130) may be fitted into the assembly hole (201) and assembled. When attaching the nozzle device (100) to the drying cover (200), the nozzle device (100) can be fixed by fitting the assembly projection (131) of the upper nozzle case (130) into the assembly hole (201) of the drying cover (200).

[0166] The drying cover (200) may include a first fastening hole (203). The first fastening hole (203) may be formed on the opposite side of the assembly hole (201) among the edges of the receiving hole (205). The other end of the upper nozzle case (130) may be fastened to the first fastening hole (203). A second fastening hole (133) formed at the other end of the upper nozzle case (130) may be fastened to the first fastening hole (203) by a fastening member (S). The nozzle device (100) may be fastened to the drying cover (200) by fitting the assembly projection (131) of the upper nozzle case (130) into the assembly hole (201) of the drying cover (200), and then fastening the fastening member (S) to the second fastening hole (133) of the upper nozzle case (130) and the first fastening hole (203) of the drying cover (200).

[0167] The drying cover (200) may include a receiving hole (205). When the nozzle device (100) is attached to the drying cover (200), a part of the nozzle device (100) may be received in the receiving hole (205). When the nozzle device (100) is attached to the drying cover (200), a lower nozzle case (140) may be received inside the receiving hole (205). The bottom of the receiving hole (205) and the bottom of the lower nozzle case (140) received inside the receiving hole (205) may be provided to have corresponding heights. The nozzle device (100) attached to the drying cover (200) may spray the washing water supplied to the nozzle device (200) through the receiving hole (205) to the heat exchangers (92, 93).

[0168] FIG. 11 is an exploded perspective view showing the nozzle and sealing member integrally formed in FIG. 5 according to various embodiments.

[0169] As shown in FIG. 11, the nozzle (110) of the nozzle device (100) and the sealing member (120) provided to surround the edge of the nozzle (110) may be provided integrally. The remaining configuration of the nozzle device (100), excluding the configuration in which the nozzle (110) and the sealing member (120) are provided integrally, may be the same as the configuration of the nozzle device (100) shown in FIG. 5 to FIG. 10.

[0170] FIG. 12 is a cross-sectional view showing that cleaning water is supplied to a nozzle device through a water supply pipe according to various embodiments, and that the cleaning water supplied to the nozzle device is sprayed into a heat exchanger through a plurality of nozzle holes. FIG. 13 is a cross-sectional view showing that the cleaning water supplied to the nozzle device to be sprayed through a plurality of nozzle holes according to various embodiments is prevented from leaking outside the upper nozzle case by a leak prevention rib.

[0171] As illustrated in FIG. 12, a connection part (135) formed in the upper nozzle case (130) of the nozzle device (100) can be connected to a water supply pipe (43, 44). Washing water supplied through the water supply pipe (43, 44) can be supplied into the nozzle device (100) through the connection part (135). Washing water supplied into the nozzle device (100) through the connection part (135) can be supplied to move along the nozzle (110). Washing water moving along the nozzle (110) can be sprayed into a heat exchanger (92, 93) through a plurality of nozzle holes (111).

[0172] As illustrated in FIG. 13, the washing water supplied to the nozzle device (100) to be sprayed through a plurality of nozzle holes (111) can be prevented / blocked / suppressed from leaking outside the upper nozzle case (130) by the leak prevention rib (150). For example, the leak prevention rib (150) can prevent / block the washing water supplied to the nozzle device (100) from leaking outside the drying cover (200). The leak prevention rib (150) may be located between the receiving hole (205) and the lower nozzle case (140). The leak prevention rib (150) may be provided to extend to a position corresponding to the bottom of the lower nozzle case (140). Washing water supplied to the nozzle (110) seated in the lower nozzle case (140) by means of a leak-prevention rib (150) located between the receiving hole (205) and the lower nozzle case (140) can fall into the drying cover (200) without leaking outside the drying cover (200).

[0173] FIG. 14 is a cross-sectional view showing that, according to various embodiments, the gap between the leak-prevention rib and the receiving hole is formed wider than the gap between the leak-prevention rib and the lower nozzle case in FIG. 13.

[0174] As illustrated in FIG. 14, the washing water supplied to the nozzle device (100) to be sprayed through a plurality of nozzle holes (111) can be prevented / blocked from leaking outside the drying cover (200) by the leak prevention rib (150). The leak prevention rib (150) may be located between the receiving hole (206) and the lower nozzle case (140). The receiving hole (20) may be formed such that the gap between the leak prevention rib (150) and the receiving hole (206) is wider than the gap between the leak prevention rib (150) and the lower nozzle case (140). That is, the receiving hole (206) may be formed wider than the receiving hole (205) illustrated in FIG. 13.

[0175] If the gap between the leak prevention rib (150) and the receiving hole (206) is narrow, the washing water may leak out of the drying cover (200) through the gap between the leak prevention rib (150) and the receiving hole (206) due to capillary action. Therefore, if the gap between the leak prevention rib (150) and the receiving hole (206) is widened, the washing water may not leak out of the drying cover (200) through the gap between the leak prevention rib (150) and the receiving hole (206) due to capillary action, but may fall into the drying cover (200).

[0176] FIG. 15 is a cross-sectional view showing that, according to various embodiments, the leak-prevention rib in FIG. 13 is arranged to extend further downward than the bottom of the lower nozzle case.

[0177] As illustrated in FIG. 15, the washing water supplied to the nozzle device (100) to be sprayed through a plurality of nozzle holes (111) can be prevented / blocked from leaking out of the drying cover (200) by the leak prevention rib (151). The leak prevention rib (151) may be located between the receiving hole (205) and the lower nozzle case (140). The leak prevention rib (151) may be provided to extend further downward than the bottom of the lower nozzle case (140). If the leak prevention rib (151) is provided to extend further downward than the bottom of the lower nozzle case (140), the washing water supplied to the nozzle (110) seated in the lower nozzle case (140) by the leak prevention rib (151) located between the receiving hole (205) and the lower nozzle case (140) can more effectively fall into the drying cover (200) without leaking outside the drying cover (200).
