[0155] At least one of the first air supply device 100 or the second air supply device 200 may be configured to circulate the air inside the tub 12 when the door 11 opens the opening 12a of the tub 12. Thus, the average flow speed of the air inside the tub 12 may be increased. The air inside the tub 12 may be uniformly mixed.

[0156] Typically, as an example, a dishwasher may use a dehumidifier to remove water vapor from the inside of the barrel during a drying stroke. As the dehumidifier absorbs water vapor, the inside of the barrel may be dried. However, in order to reuse the dehumidifier, a process of heating the dehumidifier to evaporate the moisture contained in the dehumidifier may be required. As an example, the dishwasher may provide hot air to the inside of the barrel during the drying stroke. As an example, the dishwasher may heat the wash water during the final rinse stroke before the drying stroke for condensation drying. A heater may be used to heat the dehumidifier, provide hot air and / or heat the wash water. When the heater is operating, the energy usage of the dishwasher will increase.

[0157] In contrast, the dishwasher 1 can effectively perform a drying stroke by the first air supply device 100 and / or the second air supply device 200 without a separate heater. For example, in the drying stroke, the dishwasher 1 can discharge the water vapor inside the barrel 12 to the outside of the barrel 12 while continuously circulating the air inside the barrel 12, thereby effectively evaporating the moisture remaining inside the barrel 12. Furthermore, the dishwasher 1 can improve the drying efficiency by activating the flow field inside the barrel 12. Therefore, the dishwasher 1 can perform an effective drying stroke without a heater. Moreover, compared with the above example, the dishwasher 1 omits the heating process by the heater, thereby being able to save energy.

For example, the first air supply fan 110 may generate suction force so that the air inside the barrel 12 flows into the first air supply device 100. For example, the first air supply fan 110 may generate exhaust force so that the air flowing into the first air supply device 100 flows out to the barrel 12. The first air supply fan 110 may be referred to as the first fan 110. The first air supply fan 110 may be arranged on one side of the barrel, such as Fig.10 As shown, the first blower fan 110 may be arranged outside the barrel, and thus the description may be made in the case of being arranged on the side of the barrel 12 .

[0160] For example, the first blower fan 110 may be an axial flow fan, a diagonal flow fan, or a centrifugal fan. However, the type of the first blower fan 110 is not limited thereto, as long as the first blower fan 110 generates a blower force to suck air into the barrel 12 and discharge it to the barrel 12 again.

[0161] For example, the first blower fan 110 may be configured to be driven by the first driving unit 180 (see Fig.35 ) drive. For example, the first driving unit 180 may include a motor capable of forward and reverse rotation.

[0162] For example, the suction side 111 of the first blow fan 110 may be configured to communicate with the first suction port 150. For example, the suction side 111 of the first blow fan 110 may be configured to face the first suction cap 130 described later. For example, the discharge side 112 of the first blow fan 110 may be configured to communicate with the first flow path 121. For example, the discharge side 112 of the first blow fan 110 may be configured to communicate with the second flow path 122.

[0163] The first air supply device 100 may include a first air supply duct 120. The first air supply duct 120 may be configured to guide air supplied by the first air supply fan 110. The first air supply duct 120 may be referred to as a first duct 120.

[0164] For example, the first air supply duct 120 may be formed by a first housing 120a and a second housing 120b. The first housing 120a and the second housing 120b may be detachably combined. However, it is not limited thereto, and the first air supply duct 120 may be formed by a single housing. For example, the first housing 120a and the second housing 120b may be integrally equipped.

[0168] For example, the first air supply duct 120 may form a second flow path 122 to guide the air supplied by the first air supply fan 110 away from the opening 12 a.

[0169] The air flowing on the second flow path 122 may be configured to be discharged into the tub 12 through the 1b discharge port 162, thereby forming a circulating flow of air inside the tub 12. For example, as the first shell 120a and the second shell 120b are combined, the flow path forming portion 1221 of the first shell 120a and the flow path forming portion 1222 of the second shell 120b may form the second flow path 122.

[0170] The first air supply duct 120 may include a partition 123. The partition 123 may be provided to partition the first flow path 121 of the first air supply duct 120 from the second flow path 122 of the first air supply duct 120.

[0171] For example, the partition 123 may be formed in at least one of the first shell 120a or the second shell 120b. For example, the first shell 120a may include a first partition 1231 protruding toward the second shell 120b. For example, the second shell 120b may include a second partition 1232 protruding toward the first shell 120a. For example, as the first shell 120a and the second shell 120b are combined, the first partition 1231 and the second partition 1232 may form the partition 123. However, it is not limited thereto, and one of the first partition 1231 or the second partition 1232 may form the partition 123.

[0186] The first air supply duct 120 may include a curved portion 127. The curved portion 127 may guide water flowing into the inside of the first air supply duct 120 to the tub 12. The water guided by the curved portion 127 may be discharged to the inside of the tub 12 through the first discharge port 160. For example, water contained in the air flowing in the first air supply duct 120 and / or wash water infiltrated into the first air supply duct 120 during a washing stroke (or a flushing stroke) may naturally flow to the inside of the tub 12 via the curved portion 127. Therefore, contamination caused by water remaining in the first air supply duct 120 may be prevented.

[0187] For example, the bent portion 127 may have a shape inclined downward toward the inside of the tub 12. For example, the bent portion 127 may have a curved shape.

[0188] For example, the bent portion 127 may be formed at the lower end portion of the first air supply duct 120. For example, the bent portion 127 may be provided to face the 1b-th discharge cap 142.

[0190] The water flowing on the first flow path 121 may be configured to fall toward the second flow path 122 through the third flow path 128. The water falling toward the second flow path 122 may be easily discharged to the inside of the tub 12 through the 1b discharge port 162. That is, the water flowing on the first flow path 121 may be naturally discharged to the inside of the tub 12 without being gathered in the first flow path 121. Therefore, contamination due to water remaining in the first air supply duct 120 may be prevented.

[0191] For example, as the first housing 120a and the second housing 120b are combined, the flow path forming portion 1281 of the first housing 120a and the flow path forming portion 1282 of the second housing 120b may form the first flow path 121.

[0192] The first air supply device 100 may include a first suction cap 130. The first suction cap 130 may be configured to face the first air supply fan 110. The first suction cap 130 may be detachably mounted on the inner wall of the first side 12b of the barrel 12. The first suction cap 130 may be configured to communicate with the first communication portion 1251 of the first air supply duct 120.

[0193] The first suction cap 130 can suck air inside the tub 12 by the blowing force of the first blowing fan 110 . The first suction cap 130 can form a first suction port 150 .

[0194] The first suction cap 130 may include a main body 131. The main body 131 may be configured to cover the first supply fan 110. The main body 131 may prevent at least one of foreign matter or wash water in the barrel 12 from flowing into the first supply fan 110. For example, the main body 131 may prevent wash water from penetrating into the first supply fan 110 during a washing stroke and / or a rinsing stroke. For example, foreign matter (e.g., food residues, etc.) inside the barrel 12 may be prevented from penetrating into the first supply fan 110. Thus, damage to the first supply fan 110 may be prevented, thereby extending the life of the first supply fan 110.

[0195] The first suction cap 130 may include a protrusion 132. The protrusion 132 may protrude from the body 131 toward the inside of the tub 12. The protrusion 132 may minimize suction pressure by ensuring a space between the first blow fan 110 and the first suction port 150.

[0196] The first suction cap 130 may include a suction guide rib 133. The suction guide rib 133 may be formed on one side of the main body 131 facing the first blower fan 110.

For example, the suction guide rib 133 may include a curved shape.

[0197] The suction guide rib 133 can prevent the washing water from flowing into the first blower fan 110. For example, the suction guide rib 133 can guide the washing water flowing into the first suction cap 130 to the lower part between the inner wall of the tub 12 and the first suction cap 130. As a result, the washing water flowing into the first suction cap 130 can flow downward without flowing into the first blower fan 110. The washing water guided by the suction guide rib 133 can be discharged through the discharge hole 135 (refer to FIG. Figure 6 ) is discharged into barrel 12.

[0198] The suction guide rib 133 can reduce the flow resistance of the air flowing toward the first blower fan 110. The air sucked through the suction port 150 flows along the curved shape of the suction guide rib 133, and can smoothly move toward the first blower fan 110 side.

[0199] For example, the suction guide rib 133 may be provided in plurality, the plurality of suction guide ribs 133 may be arranged to be spaced apart from each other, and the plurality of suction guide ribs 133 may be arranged in the up-down direction.

[0200] The first suction cap 130 may include a duct coupling portion 134. The duct coupling portion 134 of the first suction cap 130 may be detachably coupled to the first cap coupling portion 1261 of the first air supply duct 120. For example, as the duct coupling portion 134 rotates in a state corresponding to the first cap coupling portion 1261, the duct coupling portion 134 may be fixed to the first cap coupling portion 1261. For example, as the duct coupling portion 134 rotates in a state fixed to the first cap coupling portion 1261, the duct coupling portion 134 may be separated from the first cap coupling portion 1261.

[0201] The first suction cap 130 may include a discharge hole 135. The discharge hole 135 may discharge the wash water flowing into the inside of the first suction cap 130. The discharge hole 135 may be formed at the lower end of the first suction cap 130.

[0202] The first air supply device 100 may include a first discharge cap 140. The first discharge cap 140 may be configured to communicate the first air supply duct 120 with the inside of the tub 12. The first discharge cap 140 may be detachably mounted to the inner wall of the first side 12b of the tub 12.

[0203] The first discharge cap 140 may discharge the air guided by the first air supply duct 120 to the tub 12. The first discharge cap 140 may form a first discharge port 160.

[0204] For example, the first discharge cap 140 may include a 1a discharge cap 141. The 1a discharge cap 141 may be configured to communicate with the second communication portion 1252. The 1a discharge cap 141 may discharge the air flowing on the first flow path 121 to the tub 12. The 1a discharge cap 141 may form a 1a discharge port 161.

[0205] The 1a discharge cap 141 may include a 1a discharge guide rib 1411. The 1a discharge guide rib 1411 may be configured to guide the air guided by the first air supply duct 120 to the opening 12a side. The 1a discharge guide rib 1411 may be configured to guide the air flowing on the first flow path 121 to the opening 12a side.

[0206] For example, the opening 12a may be formed in the front of the tub 12, and the upper portion of the door 11 may be pivotally provided relative to the tub 12 with the lower portion of the door 11 as the center. In this case, for example, in a state where the door 11 opens the opening 12a, the 1a-th discharge guide rib 1411 may be provided to be inclined toward the upper front side to guide air toward the opening 12a.

[0207] For example, the first 1a discharge guide rib 1411 may be provided in plurality, the plurality of first 1a discharge guide ribs 1411 may be arranged to be spaced apart from each other, and the first 1a discharge port 161 may be formed between the plurality of first 1a discharge guide ribs 1411 .

[0208] The 1a-th discharge cap 141 may include a duct coupling portion 1412. The duct coupling portion 1412 of the 1a-th discharge cap 141 may be detachably coupled to the second cap coupling portion 1262 of the first air supply duct 120. For example, as the duct coupling portion 1412 rotates in a state corresponding to the second cap coupling portion 1262, the duct coupling portion 1412 may be fixed to the second cap coupling portion 1262. For example, as the duct coupling portion 1412 rotates in a state fixed to the second cap coupling portion 1262, the duct coupling portion 1412 may be separated from the second cap coupling portion 1262.

[0209] For example, the first discharge cap 140 may include a 1b-th discharge cap 142. The 1b-th discharge cap 142 may be configured to communicate with the third communication portion 1253. The 1b-th discharge cap 142 may discharge the air flowing on the second flow path 122 to the tub 12. The 1b-th discharge cap 142 may form a 1b-th discharge port 162.

[0210] The 1b discharge cap 142 may include a 1b discharge guide rib 1421. The 1b discharge guide rib 1421 may be configured to guide the air guided by the first air supply duct 120 away from one side of the opening 12a. The 1b discharge guide rib 1421 may guide the air flowing on the second flow path 122 away from the opening 12a.

[0211] For example, the opening 12a may be formed in the front of the tub 12, and the upper portion of the door 11 may be pivotally configured relative to the tub 12 with the lower portion of the door 11 as the center. In this case, for example, in a state where the door 11 opens the opening 12a, the 1b-th discharge guide rib 1421 may be configured to be inclined downward to guide air away from the opening 12a.

[0212] For example, the 1b-th discharge guide rib 1421 may be provided in plurality. The plurality of 1b-th discharge guide ribs 1421 may be arranged to be spaced apart from each other. The 1b-th discharge port 162 may be formed between the plurality of 1b-th discharge guide ribs 1421 .

[0213] The 1b-th discharge cap 142 may include a duct coupling portion 1422. The duct coupling portion 1422 of the 1b-th discharge cap 142 may be detachably coupled to the third cap coupling portion 1263 of the first air supply duct 120. For example, as the duct coupling portion 1422 rotates in a state corresponding to the third cap coupling portion 1263, the duct coupling portion 1422 may be fixed to the third cap coupling portion 1263. For example, as the duct coupling portion 1422 rotates in a state fixed to the third cap coupling portion 1263, the duct coupling portion 1422 may be separated from the third cap coupling portion 1263.

[0214] The first air supply device 100 may include a first suction port 150 for sucking air inside the barrel 12 by the first air supply fan 110. The first suction port 150 may be provided on one side of the first flow path 121. The first suction port 150 may be provided on one side of the second flow path 122. The first suction port 150 may be formed by the first suction cap 130. For example, the first suction port 150 may be formed between the inner wall of the barrel 12 and the main body 131.

[0215] For example, the opening 12a may be formed in front of the barrel 12, and the upper portion of the door 11 may be pivotally equipped relative to the barrel 12 with the lower portion of the door 11 as the center. In this case, for example, the first suction port 150 may be arranged at the rear upper portion of the first side 12b of the barrel 12. The first suction port 150 may suck in the air inside the barrel 12 at the rear side of the first side 12b of the barrel 12 relatively far from the opening 12a and at the upper side of the first side 12b of the barrel 12 where the air flows quickly. Thereby, the air inside the barrel 12 may flow actively, and the drying performance of the dishwasher 1 may be improved. However, this is merely exemplary, and as long as the first suction port 150 can suck in the air inside the barrel 12, its position is not limited.

[0216] The first air supply device 100 may include a first outlet 160 for discharging air flowing on a flow path formed in the first air supply duct 120. The first air supply device 100 may include at least one of the first outlet 1a 161 and the first outlet 1b 162.

[0217] For example, the first exhaust port 160 may include a first exhaust port 161 for exhausting the air flowing on the first flow path 121. The first exhaust port 161 may be provided at the other side of the first flow path 121. The first exhaust port 161 may be formed by the first exhaust cap 141. The air exhausted through the first exhaust port 161 may flow toward the opening 12a.

[0218] For example, the opening 12a may be formed in front of the barrel 12, and the upper portion of the door 11 may be pivotally equipped relative to the barrel 12 with the lower portion of the door 11 as the center. For example, the 1a exhaust port 161 may be arranged adjacent to the opening 12a. For example, the 1a exhaust port 161 may be arranged in front of the first suction port 150. The 1a exhaust port 161 may be arranged in the front upper portion of the first side 12b of the barrel 12. The 1a exhaust port 161 may discharge the air guided by the first air supply duct 120 toward the opening 12a, thereby allowing the water vapor inside the barrel 12 to be smoothly discharged to the outside of the barrel 12. Therefore, the humidity inside the barrel 12 may be reduced.

[0219] For example, the first exhaust port 160 may include a 1b exhaust port 162 for exhausting the air flowing on the second flow path 122. The 1b exhaust port 162 may be provided at the other side of the second flow path 122. The 1b exhaust port 162 may be formed by the 1b exhaust cap 142. The air exhausted through the 1b exhaust port 162 may flow toward a side away from the opening 12a.

[0220] For example, the opening 12a may be formed in front of the barrel 12, and the upper portion of the door 11 may be pivotally equipped relative to the barrel 12 with the lower portion of the door 11 as the center. In the drying stroke, the door 11 may open the opening 12a to a predetermined range. At this time, the upper portion of the barrel 12 may be exposed to the outside of the barrel 12 through the opening 12a, and the lower portion of the barrel 12 may be covered by the door 11 so as not to be exposed to the outside of the barrel 12. Therefore, the drying efficiency of the lower portion of the barrel 12 may not be as good as the drying efficiency of the upper portion of the barrel 12. For example, compared with the 1a discharge port 161, the 1b discharge port 162 may be arranged relatively away from the opening 12a. For example, the 1b discharge port 162 may be arranged below the 1a discharge port 161. For example, the 1b discharge port 162 may be arranged below the first suction port 150. The 1b discharge port 162 may be arranged at the lower portion of the first side 12b of the barrel 12. The first discharge port 162 may be disposed at the lower portion of the first side 12b of the tub 12 to discharge the air guided by the first air supply duct 120, thereby concentrating air supply to the portion with relatively reduced drying performance. As a result, the drying efficiency of the dishwasher 1 may be improved.

[0221] The first air supply device 100 may include a sealing member 171. The sealing member 171 may be configured to prevent the air flowing into the first air supply duct 120 from flowing out between the first air supply duct 120 and the tub 12.

[0222] The first air supply device 100 may include a sealing member 172. The sealing member 172 may be configured to prevent the air flowing out of the first air supply duct 120 from flowing out between the first air supply duct 120 and the tub 12. The sealing member 172 may be arranged to correspond to the first discharge cap 141 to seal between the first air supply duct 120 and the tub 12.

[0223] The first air supply device 100 may include a sealing member 173. The sealing member 173 may be configured to prevent the air flowing out of the first air supply duct 120 from flowing out between the first air supply duct 120 and the tub 12. The sealing member 173 may be arranged to correspond to the 1b-th discharge cap 142 to seal between the first air supply duct 120 and the tub 12.

[0224] Reference Fig.10 and Fig.11 , an example of the flow of air is described.

[0225] During the drying process, the door 11 can open the opening 12a of the barrel 12 to a predetermined range (refer to Figure 2 ). The first air supply device 100 can be configured to operate in a state where the door 11 opens the opening 12a of the barrel 12 to a predetermined range. The first air supply fan 110 can generate air supply force as it rotates. The air inside the barrel 12 can pass through the first suction cap 130 and flow into the first air supply duct 120 by the air supply force of the first air supply fan 110. The air flowing into the first air supply duct 120 can flow along the flow path formed inside the first air supply duct 120. A portion of the air flowing into the first air supply duct 120 can flow along the first flow path 121. The remaining portion of the air flowing into the first air supply duct 120 can flow along the second flow path 122 separated from the first flow path 121.

[0226] The air guided by the first flow path 121 may flow out to the inside of the barrel 12 through the 1a discharge cap 141. The air guided by the first flow path 121 may be guided to the side adjacent to the opening 12a through the 1a discharge guide rib 1411 of the 1a discharge cap 141. The air discharged through the 1a discharge cap 141 may be discharged to the inside of the barrel 12 to discharge the water vapor inside the barrel 12 to the outside of the barrel 12. The water vapor inside the barrel 12 may be discharged to the outside of the barrel 12 through the opening 12a by the air discharged through the 1a discharge cap 141. At least a portion of the air discharged through the 1a discharge cap 141 may be mixed with the air and / or water vapor inside the barrel 12 and discharged to the outside of the barrel 12.

[0227] The air guided by the second flow path 122 may flow out to the inside of the barrel 12 through the 1b discharge cap 142. The air guided by the second flow path 122 may be guided to the side away from the opening 12a through the 1b discharge guide rib 1421 of the 1b discharge cap 142. The air discharged through the 1b discharge cap 142 may be discharged to the inside of the barrel 12 to form a circulating airflow inside the barrel 12. That is, the air inside the barrel 12 may be circulated by the first air supply device 100. Therefore, the air inside the barrel 12 may be uniformly mixed.

[0228] Reference Fig.12 , an example of the flow of water flowing into the first air supply device 100 is described.

[0229] The water flowing on the first flow path 121 can be guided downward along the third flow path 128 formed by the first air supply duct 120. The water flowing on the first flow path 121 can fall along the third flow path 128. The water in the first flow path 121 can flow to the second flow path 122 through the third flow path 128. The water flowing into the second flow path 122 can flow toward the 1b discharge cap 142 through the bent portion 127. The water flowing to the 1b discharge cap 142 can flow out to the inside of the barrel 12 through the 1b discharge port 162 formed in the 1b discharge cap 142.

Fig.18 An example of a second air supply device according to an embodiment is shown in cross section.

[0231] The second air supply device 200 may include a second air supply fan 210. The second air supply fan 210 may generate air supply force as it rotates. For example, the second air supply fan 210 may generate suction force so that the air inside the barrel 12 flows into the second air supply device 200. For example, the second air supply fan 210 may generate exhaust force so that the air flowing into the second air supply device 200 flows out to the barrel 12. The second air supply fan 210 may be referred to as the second fan 210.

[0232] For example, the second blower fan 210 may be an axial flow fan, a diagonal flow fan, or a centrifugal fan. However, the type of the second blower fan 210 is not limited thereto, as long as the second blower fan 210 generates a blower force to suck air into the barrel 12 and discharge it to the barrel 12 again.

[0233] For example, the second blower fan 210 may be configured to be driven by the second drive unit 280 (see Fig.35 ) drive. For example, the second driving unit 280 may include a motor capable of forward and reverse rotation.

[0234] For example, the suction side 211 of the second blower fan 210 may be configured to communicate with the second suction port 250. For example, the suction side 211 of the second blower fan 210 may be configured to face the second suction cap 230 described later. For example, the discharge side 212 of the second blower fan 210 may be configured to communicate with the first flow path 221. For example, the discharge side 212 of the second blower fan 210 may be configured to communicate with the second flow path 222.

[0235] The second air supply device 200 may include a second air supply duct 220. The second air supply duct 220 may be configured to guide the air supplied by the second air supply fan 210. The second air supply duct 220 may be referred to as a second duct 220.

[0236] For example, the second air supply duct 220 may be formed by a first housing 220a and a second housing 220b. The first housing 220a and the second housing 220b may be detachably combined. However, this is not limited thereto, and the second air supply duct 220 may be formed by a single housing. For example, the first housing 220a and the second housing 220b may be integrally equipped.

[0237] The second air supply duct 220 may form a flow path to guide air.

[0239] The air flowing on the first flow path 221 may be configured to be discharged into the tub 12 through the 2a discharge port 261, thereby forming a circulating flow of air inside the tub 12. For example, as the first shell 220a and the second shell 220b are combined, the flow path forming portion 2211 of the first shell 220a and the flow path forming portion 2212 of the second shell 220b may form the first flow path 221.

[0240] For example, the second air supply duct 220 may form a second flow path 222 to guide air away from the opening 12 a.

[0241] The air flowing on the second flow path 222 may be configured to be discharged into the tub 12 through the 2b discharge port 262, thereby forming a circulating flow of air inside the tub 12. For example, as the first shell 220a and the second shell 220b are combined, the flow path forming portion 2221 of the first shell 220a and the flow path forming portion 2222 of the second shell 220b may form the second flow path 222.

[0242] The second air supply duct 220 may include a partition 223. The partition 223 may be provided to partition the first flow path 221 of the second air supply duct 220 from the second flow path 222 of the second air supply duct 220. The partition 223 may prevent the air flowing on the first flow path 221 and the air flowing on the second flow path 222 from mixing with each other.

[0243] For example, the partition 223 may be formed in at least one of the first shell 220a or the second shell 220b.

[0256] The second air supply duct 220 may include a second cap joint 2262. The second cap joint 2262 may be detachably mounted with the 2a discharge cap 241. For example, the second cap joint 2262 may be formed around the second communication portion 2252. For example, the second cap joint 2262 may be provided in plurality.

[0258] The second air supply duct 220 may include a bent portion 227. The bent portion 227 may guide water flowing into the inside of the second air supply duct 220 to the tub 12. The water guided by the bent portion 227 may be discharged to the inside of the tub 12 through the second discharge port 260. For example, water contained in the air flowing in the second air supply duct 220 and / or wash water infiltrated into the second air supply duct 220 during a washing stroke (or a rinse stroke) may naturally flow to the inside of the tub 12 via the bent portion 227. Therefore, contamination due to water remaining in the second air supply duct 220 may be prevented.

[0259] For example, the bent portion 227 may have a shape inclined downward toward the inside of the tub 12. For example, the bent portion 227 may have a curved shape.

For example, foreign matter (e.g., food residues, etc.) inside the barrel 12 may be prevented from penetrating into the second supply fan 210. Thus, damage to the second supply fan 210 may be prevented, thereby extending the life of the second supply fan 210.

[0264] The second suction cap 230 may include a protrusion 232. The protrusion 232 may protrude from the body portion 231 toward the inside of the tub 12. The protrusion 232 may minimize the suction pressure by ensuring a space between the second blow fan 210 and the second suction port 250.

[0265] The second suction cap 230 may include a suction guide rib 233. The suction guide rib 233 may be formed on one side of the main body 231 facing the second blower fan 210. The suction guide rib 233 may be configured to guide air to the second blower fan 210. For example, the suction guide rib 233 may include a downwardly inclined shape. For example, the suction guide rib 233 may include a curved shape.

[0266] The suction guide rib 233 can prevent the washing water from flowing into the second blower fan 210. For example, the suction guide rib 233 can guide the washing water flowing into the second suction cap 230 to the lower part between the inner wall of the tub 12 and the second suction cap 230. As a result, the washing water flowing into the second suction cap 230 can flow downward without flowing into the second blower fan 210. The washing water guided by the suction guide rib 233 can be discharged through the discharge hole 235 (see Fig.14 ) is discharged into barrel 12.

[0267] The suction guide rib 233 can reduce the flow resistance of the air flowing toward the second blower fan 210. The air sucked through the second suction port 250 flows along the curved shape of the suction guide rib 233, and can smoothly move toward the second blower fan 210 side.

[0268] For example, the suction guide rib 233 may be provided in plurality, the plurality of suction guide ribs 233 may be arranged to be spaced apart from each other, and the plurality of suction guide ribs 233 may be arranged in the up-down direction.

[0269] The second suction cap 230 may include a duct coupling portion 234. The duct coupling portion 234 of the second suction cap 230 may be detachably coupled to the first cap coupling portion 2261 of the second air supply duct 220. For example, as the duct coupling portion 234 rotates in a state corresponding to the first cap coupling portion 2261, the duct coupling portion 234 may be fixed to the first cap coupling portion 2261. For example, as the duct coupling portion 234 rotates in a state fixed to the first cap coupling portion 2261, the duct coupling portion 234 may be separated from the first cap coupling portion 2261.

[0270] The second suction cap 230 may include a discharge hole 235. The discharge hole 235 may discharge the wash water flowing into the inside of the second suction cap 230. The discharge hole 235 may be formed at the lower end of the second suction cap 230. For example, the wash water guided by the suction guide rib 233 may naturally flow downward and be discharged into the inside of the tub 12 through the discharge hole 235.

[0271] The second air supply device 200 may include a second discharge cap 240. The second discharge cap 240 may be configured to communicate the second air supply duct 220 with the inside of the tub 12. The second discharge cap 240 may be detachably mounted to the inner wall of the second side 12c of the tub 12.

[0272] The second discharge cap 240 may discharge the air guided by the second air supply duct 220 to the tub 12. The second discharge cap 240 may form a second discharge port 260.

[0273] For example, the second discharge cap 240 may include a 2a discharge cap 241. The 2a discharge cap 241 may be configured to communicate with the second communication portion 2252. The 2a discharge cap 241 may discharge the air flowing on the first flow path 221 to the tub 12. The 2a discharge cap 241 may form a 2a discharge port 261.

[0274] The 2a discharge cap 241 may include a 2a discharge guide rib 2411. The 2a discharge guide rib 2411 may be configured to guide the air guided by the second air supply duct 220 away from one side of the opening 12a. The 2a discharge guide rib 2411 may be configured to guide the air flowing on the first flow path 221 away from the opening 12a.

[0275] For example, the opening 12a may be formed in the front of the tub 12, and the upper portion of the door 11 may be pivotally provided relative to the tub 12 with the lower portion of the door 11 as the center. In this case, for example, in a state where the door 11 opens the opening 12a, the 2a discharge guide rib 2411 may be inclined downward to guide air away from the opening 12a.

[0276] For example, the 2a-th discharge guide rib 2411 may be provided in plurality, the plurality of 2a-th discharge guide ribs 2411 may be arranged to be spaced apart from each other, and the 2a-th discharge port 261 may be formed between the plurality of 2a-th discharge guide ribs 2411 .

[0277] The 2a discharge cap 241 may include a duct coupling portion 2412. The duct coupling portion 2412 of the 2a discharge cap 241 may be detachably coupled to the second cap coupling portion 2262 of the second air supply duct 220. For example, as the duct coupling portion 2412 rotates in a state corresponding to the second cap coupling portion 2262, the duct coupling portion 2412 may be fixed to the second cap coupling portion 2262. For example, as the duct coupling portion 2412 rotates in a state fixed to the second cap coupling portion 2262, the duct coupling portion 2412 may be separated from the second cap coupling portion 2262.

[0278] For example, the second discharge cap 240 may include a 2b-th discharge cap 242. The 2b-th discharge cap 242 may be configured to communicate with the third communication portion 2253. The 2b-th discharge cap 242 may discharge the air flowing on the second flow path 222 to the tub 12. The 2b-th discharge cap 242 may form a 2b-th discharge port 262.

[0279] The 2b discharge cap 242 may include a 2b discharge guide rib 2421. The 2b discharge guide rib 2421 may be configured to guide the air guided by the second air supply duct 220 away from one side of the opening 12a. The 2b discharge guide rib 2421 may be configured to guide the air flowing on the second flow path 222 away from the opening 12a.

[0280] For example, the opening 12a may be formed in the front of the tub 12, and the upper portion of the door 11 may be pivotally equipped relative to the tub 12 with the lower portion of the door 11 as the center. In this case, for example, in a state where the door 11 opens the opening 12a, the 2b-th discharge guide rib 2421 may be inclined downward to guide air away from the opening 12a.

[0281] For example, the 2b-th discharge guide rib 2421 may be provided in plurality. The plurality of 2b-th discharge guide ribs 2421 may be arranged to be spaced apart from each other. The 2b-th discharge port 262 may be formed between the plurality of 2b-th discharge guide ribs 2421 .

[0282] The 2b discharge cap 242 may include a duct coupling portion 2422. The duct coupling portion 2422 of the 2b discharge cap 242 may be detachably coupled to the third cap coupling portion 2263 of the second air supply duct 220. For example, as the duct coupling portion 2422 rotates in a state corresponding to the third cap coupling portion 2263, the duct coupling portion 2422 may be fixed to the third cap coupling portion 2263. For example, as the duct coupling portion 2422 rotates in a state fixed to the third cap coupling portion 2263, the duct coupling portion 2422 may be separated from the third cap coupling portion 2263.

[0283] The second air supply device 200 may include a second suction port 250 for sucking air into the barrel 12 by the second air supply fan 210. The second suction port 250 may be provided on one side of the first flow path 221. The second suction port 250 may be provided on one side of the second flow path 222. The second suction port 250 may be formed by the second suction cap 230. For example, the second suction port 250 may be formed between the inner wall of the barrel 12 and the main body 231.

[0284] For example, the opening 12a may be formed in front of the barrel 12, and the upper portion of the door 11 may be pivotally equipped relative to the barrel 12 with the lower portion of the door 11 as the center. In this case, for example, the second suction port 250 may be arranged at the rear upper portion of the second side 12c of the barrel 12. The second suction port 250 may suck in the air inside the barrel 12 at the rear side of the second side 12c of the barrel 12 relatively far from the opening 12a and at the upper side of the second side 12c of the barrel 12 where the air flows quickly. Therefore, the air inside the barrel 12 may flow actively, and the drying performance of the dishwasher 1 may be improved. However, this is merely exemplary, and as long as the second suction port 250 can suck in the air inside the barrel 12, its position is not limited.

[0285] The second air supply device 200 may include a second outlet 260 for discharging air flowing on a flow path formed in the second air supply device 200. The second air supply device 200 may include at least one of the second-a outlet 261 and the second-b outlet 262.

[0286] For example, the second exhaust port 260 may include a 2a exhaust port 261 for exhausting the air flowing on the first flow path 221. The 2a exhaust port 261 may be provided at the other side of the first flow path 221. The 2a exhaust port 261 may be formed by the 2a exhaust cap 241. The air exhausted through the 2a exhaust port 261 may flow toward a side away from the opening 12a.

[0287] For example, the opening 12a may be formed in front of the barrel 12, and the upper portion of the door 11 may be pivotally equipped relative to the barrel 12 with the lower portion of the door 11 as the center. In the drying stroke, the door 11 may open the opening 12a to a predetermined range. At this time, the upper portion of the barrel 12 may be exposed to the outside of the barrel 12 through the opening 12a, and the lower portion of the barrel 12 may be covered by the door 11 so as not to be exposed to the outside of the barrel 12. Therefore, the drying efficiency of the lower portion of the barrel 12 may not be as good as the drying efficiency of the upper portion of the barrel 12. For example, the 2a exhaust port 261 may be arranged away from the opening 12a. For example, the 2a exhaust port 261 may be arranged below the second suction port 250. The 2a exhaust port 261 may be arranged at the lower portion of the second side 12c of the barrel 12. The 2a exhaust port 261 may be arranged at the rear lower portion of the second side 12c of the barrel 12. The 2a exhaust port 261 may concentrate air supply to the portion where the drying performance is relatively reduced. Finally, the drying efficiency of the dishwasher 1 can be improved.

[0288] For example, the second exhaust port 260 may include a 2b exhaust port 262 for exhausting the air flowing on the second flow path 222. The 2b exhaust port 262 may be provided at the other side of the second flow path 222. The 2b exhaust port 262 may be formed by the 2b exhaust cap 242. The air exhausted through the 2b exhaust port 262 may flow toward a side away from the opening 12a.

[0289] For example, the opening 12a may be formed in front of the barrel 12, and the upper portion of the door 11 may be pivotally equipped relative to the barrel 12 with the lower portion of the door 11 as the center. In the drying stroke, the door 11 may open the opening 12a to a predetermined range. At this time, the upper portion of the barrel 12 may be exposed to the outside of the barrel 12 through the opening 12a, and the lower portion of the barrel 12 may be covered by the door 11 so as not to be exposed to the outside of the barrel 12. Therefore, the drying efficiency of the lower portion of the barrel 12 may not be as good as the drying efficiency of the upper portion of the barrel 12. For example, the 2b exhaust port 262 may be arranged below the second suction port 250. For example, the 2b exhaust port 262 may be arranged in the front-to-back direction with the 2a exhaust port 261. For example, the 2b exhaust port 262 may be arranged in front of the 2a exhaust port 261. The 2b exhaust port 262 may be arranged at the lower portion of the second side 12c of the barrel 12. The 2b exhaust port 262 may concentrate air supply to a portion where the drying performance is relatively reduced. Finally, the drying efficiency of the dishwasher 1 can be improved.

[0290] For example, except for the position, the 2a discharge cap 241 and the 2b discharge cap 242 may be substantially the same. For example, except for the position, the 2a discharge port 261 and the 2b discharge port 262 may be substantially the same. The second air supply device 200 may discharge air centrally toward the lower part of the barrel 12 through the 2a discharge port 261 and the 2b discharge port 262. Thereby, the drying efficiency of the lower part of the barrel 12 can be improved. The tableware located at the lower part of the barrel 12 can be effectively dried.

[0291] The second air supply device 200 may include a sealing member 271. The sealing member 271 may be configured to prevent the air flowing into the second air supply duct 220 from flowing out between the second air supply duct 220 and the tub 12. The sealing member 271 may be arranged to correspond to the second suction cap 230 to seal between the second air supply duct 220 and the tub 12.

[0292] The second air supply device 200 may include a sealing member 272. The sealing member 272 may be configured to prevent the air discharged from the second air supply duct 220 from flowing out between the second air supply duct 220 and the tub 12. The sealing member 272 may be arranged to correspond to the 2a discharge cap 241 to seal between the second air supply duct 220 and the tub 12.

[0293] The second air supply device 200 may include a sealing member 273. The sealing member 273 may be configured to prevent the air discharged from the second air supply duct 220 from flowing out between the second air supply duct 220 and the tub 12. The sealing member 273 may be arranged to correspond to the 2b discharge cap 242 to seal between the second air supply duct 220 and the tub 12.

[0294] Reference Fig.17 and Fig.18 , an example of the flow of air is described.

[0295] During the drying process, the door 11 can open the opening 12a of the barrel 12 to a predetermined range (refer to Figure 2 ). The second air supply device 200 can be configured to operate in a state where the door 11 opens the opening 12a of the barrel 12 to a predetermined range. The second air supply fan 210 can generate air supply force as it rotates. The air inside the barrel 12 can pass through the second suction cap 230 and flow into the second air supply duct 220 by the air supply force of the second air supply fan 210. The air flowing into the second air supply duct 220 can flow along the flow path formed inside the second air supply duct 220. A portion of the air flowing into the second air supply duct 220 can flow along the first flow path 221. The remaining portion of the air flowing into the second air supply duct 220 can flow along the second flow path 222 separated from the first flow path 221.

[0296] The air guided by the first flow path 221 may flow out to the inside of the barrel 12 through the 2a discharge cap 241. The air guided by the first flow path 221 may be guided to a side away from the opening 12a by the 2a discharge guide rib 2411 of the 2a discharge cap 241. The air discharged through the 2a discharge cap 241 may be discharged to the inside of the barrel 12, thereby forming a circulating airflow inside the barrel 12. Therefore, the air inside the barrel 12 may be uniformly mixed.

[0297] The air guided by the second flow path 222 may flow out to the inside of the barrel 12 through the 2b discharge cap 242. The air guided by the second flow path 222 may be guided to a side away from the opening 12a by the 2b discharge guide rib 2421 of the 2b discharge cap 242. The air discharged through the 2b discharge cap 242 may be discharged to the inside of the barrel 12, thereby forming a circulating airflow inside the barrel 12. Therefore, the air inside the barrel 12 may be uniformly mixed.

[0364] Fig.34 An example of a stroke cycle of a dishwasher according to an embodiment and an example of a stroke cycle of a dishwasher according to a comparative example are shown.

[0365] Generally, a dishwasher can perform a washing stroke for washing dishes using water and detergent, a rinsing stroke for rinsing the dishes, and a drying stroke for removing moisture remaining on the dishes. The rinsing stroke may include a first rinsing stroke for removing detergent stuck on the dishes during the washing stroke and a second rinsing stroke for finally rinsing the dishes after draining water used in the first rinsing stroke.

[0366] Referring to an example of a stroke cycle of a dishwasher according to a comparative example, in the second rinse stroke, there may be an operation of heating the washing water by starting a heater. By heating the washing water in the second rinse stroke and spraying the high-temperature washing water onto the tableware, the temperature inside the barrel can be increased, thereby promoting the evaporation of the remaining water on the tableware. After the second rinse, the drying stroke can be performed by condensation drying and natural convection drying by opening the door. However, in the case of the dishwasher according to the comparative example, a large amount of energy may be required in the process of heating the washing water in the second rinse. Therefore, the energy efficiency of the dishwasher may be reduced. Moreover, it may be difficult to effectively remove the moisture remaining in the barrel and the tableware only by condensation drying and natural convection drying. For example, the drying time of the dishwasher may increase. For example, because the dishwasher is not effectively dried, the residual moisture may cause contamination, mold, component damage, etc.

[0367] Referring to an example of a stroke cycle of the dishwasher 1 according to an embodiment, in the second rinse stroke, the operation of heating the washing water can be omitted. Furthermore, the dishwasher 1 performs a drying stroke by condensation drying and natural convection drying by opening the door, and finally, forced convection drying can be performed using the air supply device 80. For example, the dishwasher 1 may include a first air supply device 100 and a second air supply device 200. For example, the dishwasher 1 can easily discharge the water vapor inside the barrel 12 to the outside of the barrel 12 while circulating the air inside the barrel 12 to centrally supply air to a portion where the drying efficiency is reduced. In short, the dishwasher 1 can reduce the energy required to heat the washing water in the second rinse stroke. Furthermore, the dishwasher 1 can effectively remove the moisture remaining inside the barrel 12 and on the dishes by forced convection drying. The dishwasher 1 can improve the drying efficiency by causing forced convection inside the barrel 12.

[0394] Reference Fig.37 , after the door 11 is opened and a predetermined time t2 has passed, a driving voltage may be supplied to the first air supply device 100. After the driving of the first air supply device 100 starts, a variable driving voltage may be supplied to the first air supply device 100 during a predetermined time t3. For example, it may be configured to alternately supply a first driving voltage V1 and a second driving voltage V2 to the first air supply device 100. Therefore, the air supply force of the first air supply device 100 may be periodically changed. The rotation speed of the first air supply fan 110 may be periodically changed.

After the driving of the second air supply device 200 begins, a variable driving voltage may be supplied to the second air supply device 200 during a predetermined time t3. For example, it may be configured to alternately supply a first driving voltage V1 and a second driving voltage V2 to the first air supply device 100. Therefore, the air supply force of the second air supply device 200 may be periodically changed. The rotation speed of the second air supply fan 210 may be periodically changed.

[0396] Reference Fig.38 , after the door 11 is opened and the predetermined time t2 has passed, the driving voltage may be supplied to the first air supply device 100. After the door 11 is opened and the predetermined time t2 has passed, the driving voltage may be supplied to the second air supply device 200. At the start of the driving of the first air supply device 100 and during the predetermined time t3, it may be configured to alternately supply the first driving voltage V1 and the second driving voltage V2 to the first air supply device 100. At the start of the driving of the second air supply device 200 and during the predetermined time t3, it may be configured to alternately supply the second driving voltage V2 and the first driving voltage V1 to the second air supply device 200. At a time point, in the case of supplying the first driving voltage V1 to the first air supply device 100, the second driving voltage V2 may be supplied to the second air supply device 200. At a time point, in the case of supplying the second driving voltage V2 to the first air supply device 100, the first driving voltage V1 may be supplied to the second air supply device 200.

[0400] Fig.40 is a flowchart illustrating an example of a method for controlling a dishwasher in a drying process according to an embodiment.

[0401] Reference Fig.40 When the drying process starts (1100) and the preset time t1 has passed ("Yes" at 1200), the dishwasher 1 can control the door 11 to open (1300). For example, the door 11 can open the opening 12a of the tub 12 to a predetermined range (refer to Figure 2 ).

[0402] When the drying course starts ( 1100 ) and the preset time t1 has not elapsed ( “No” at 1200 ), the dishwasher 1 may keep the door 11 in a closed state.

[0403] When the door 11 is opened (1300) and a preset time t2 has passed ("Yes" at 1400), the dishwasher 1 can start driving the air supply device 80 (1500). That is, the air supply device 80 can be switched from the closed (OFF) state to the open (ON) state. For example, when the door 11 is opened (1300) and a preset time t2 has passed ("Yes" at 1400), the driving of the first air supply device 100 can be started. For example, when the door 11 is opened (1300) and a preset time t2 has passed ("Yes" at 1400), the driving of the second air supply device 200 can be started.

[0404] When the door 11 is opened ( 1300 ) and the preset time t2 has not elapsed ( “No” at 1400 ), the air supply device 80 may remain in the closed (OFF) state.

[0405] When the driving of the air supply device 80 starts (1500) and a preset time t3 has passed ("Yes" of 1600), the dishwasher 1 can end the driving of the air supply device 80 (1700). That is, the air supply device 80 can be switched from the ON state to the OFF state. For example, when the driving of the air supply device 80 starts (1500) and a preset time t3 has passed ("Yes" of 1600), the operation of the first air supply device 100 can be interrupted. For example, when the driving of the air supply device 80 starts (1500) and a preset time t3 has passed ("Yes" of 1600), the operation of the second air supply device 200 can be interrupted.

[0406] When the driving of the air blowing device 80 starts (1500) and the preset time t3 has not elapsed (No at 1600), the air blowing device 80 may be configured to continue driving. The air blowing device 80 may be kept in the ON state.

[0407] When the driving of the air supply device 80 ends ( 1700 ), the dishwasher 1 may end the drying process ( 1800 ).

[0408] Fig.41 is a flowchart illustrating an example of a method of controlling a dishwasher when the temperature inside a tub reaches a target temperature according to an embodiment.

[0409] Reference Fig.41 , the dishwasher 1 may start driving the air supply device 80 (2100) and compare the temperature inside the tub 12 with the temperature outside (2200). For example, the control unit 300 may determine whether the driving of the air supply device 80 is finished by comparing the temperature inside the tub 12 with the temperature outside. For example, the temperature inside the tub 12 may be measured by the temperature sensor 600.

[0410] When the driving of the air supply device 80 starts (2100) and the temperature inside the barrel 12 reaches the external temperature, the driving of the air supply device 80 can be terminated.

[0411] For example, when the air supply device 80 starts to drive (2100) and the temperature inside the barrel 12 is lower than the external temperature ("Yes" of 2200), the driving of the air supply device 80 can be ended (2300). For example, when the air supply device 80 starts to drive (2100) and the temperature inside the barrel 12 is lower than the external temperature ("Yes" of 2200), the operation of the first air supply device 100 can be interrupted. For example, when the air supply device 80 starts to drive (2100) and the temperature inside the barrel 12 is lower than the external temperature ("Yes" of 2200), the operation of the second air supply device 200 can be interrupted.

[0412] For example, when the air supply device 80 starts to drive (2100) and the temperature inside the tub 12 is not lower than the external temperature (No at 2200), the air supply device 80 may be configured to continue to drive. The air supply device 80 may remain in the ON state.

[0413] Fig.42 is a flowchart illustrating an example of a method of controlling a dishwasher when the humidity inside a tub reaches a target humidity according to an embodiment.

[0414] Reference Fig.42 , the dishwasher 1 starts driving the air supply device 80 (3100), and the humidity inside the barrel 12 can be compared with a preset target humidity (3200). For example, the control unit 300 can determine whether the driving of the air supply device 80 is completed by comparing the humidity inside the barrel 12 with a preset target humidity. For example, the humidity inside the barrel 12 can be measured by the humidity sensor 700. The target humidity can be set by the input unit 410.

[0415] When the driving of the air supply device 80 starts ( 3100 ) and the humidity inside the barrel 12 reaches a preset target humidity, the driving of the air supply device 80 may be terminated.

[0416] For example, when the driving of the air supply device 80 starts (3100) and the humidity inside the barrel 12 becomes lower than the preset target humidity ("Yes" of 3200), the driving of the air supply device 80 can be ended (3300). For example, when the driving of the air supply device 80 starts (3100) and the humidity inside the barrel 12 becomes lower than the preset target humidity ("Yes" of 3200), the operation of the first air supply device 100 can be interrupted. For example, when the driving of the air supply device 80 starts (3100) and the humidity inside the barrel 12 becomes lower than the preset target humidity ("Yes" of 3200), the operation of the second air supply device 200 can be interrupted.

[0417] For example, when the air supply device 80 starts to be driven (3100) and the humidity inside the tub 12 is not below the preset target humidity ("No" in 3200), the air supply device 80 may be configured to continue to be driven. The air supply device 80 may remain in the ON state.

[0418] Fig.43 The flowchart shows an example of a method for controlling a dishwasher according to an embodiment of the present invention, which controls an air blowing device by comparing the temperature inside a tub with a target temperature when a preset time has passed since the air blowing device starts to be driven.

[0419] Reference Fig.43 After the air supply device 80 starts to be driven (4100) and a preset time t4 has passed (“Yes” in 4200), the dishwasher 1 can compare the temperature inside the tub 12 with the external temperature (4300). For example, the control unit 300 can determine whether the driving of the air supply device 80 has ended by comparing the temperature inside the tub 12 with the external temperature. For example, the temperature inside the tub 12 can be measured by the temperature sensor 600.

[0420] After the driving of the air supply device 80 starts ( 4100 ) and a preset time t4 has passed ( “Yes” in 4200 ), when the temperature inside the tub 12 reaches the external temperature, the dishwasher 1 may end the driving of the air supply device 80 ( 4400 ).

[0421] For example, when the temperature inside the barrel 12 is lower than the external temperature (“Yes” in 4300), the driving of the air supply device 80 can be terminated (4400). For example, when the temperature inside the barrel 12 is lower than the external temperature (“Yes” in 4300), the operation of the first air supply device 100 can be interrupted. For example, when the temperature inside the barrel 12 is lower than the external temperature (“Yes” in 4300), the operation of the second air supply device 200 can be interrupted.

[0422] After the air supply device 80 starts to be driven ( 4100 ) and a preset time t4 has passed ( “Yes” at 4200 ), if the temperature inside the tub 12 has not reached the external temperature, the dishwasher 1 may control the air supply device 80 to improve the drying performance.

[0423] For example, when the temperature inside the barrel 12 does not reach below the external temperature ("No" of 4300), the rotation speed of the air supply device 80 can be adjusted (4500). For example, the control unit 300 can control the air supply force of the air supply device 80 to be increased than before. For example, the control unit 300 can control the rotation speed of the air supply device 80 to be increased than before. For example, when the temperature inside the barrel 12 does not reach below the external temperature ("No" of 4300), the control unit 300 can increase the rotation speed of the first air supply device 100. For example, when the temperature inside the barrel 12 does not reach below the external temperature ("No" of 4300), the control unit 300 can increase the rotation speed of the second air supply device 200.

[0424] For example, after the rotation speed of the air supply device 80 is adjusted ( 4500 ), when a preset time t5 has passed ( “Yes” in 4600 ), the driving of the air supply device 80 may be terminated ( 4400 ).

[0425] Fig.44 The flowchart shows an example of a method for controlling a dishwasher according to an embodiment of the present invention for controlling an air blowing device by comparing the humidity inside a drum with a target humidity when a preset time has passed since the air blowing device started to be driven.

[0426] Reference Fig.44 After the air supply device 80 starts to drive (5100) and a preset time t4 has passed ("Yes" in 5200), the dishwasher 1 may compare the humidity inside the tub 12 with the preset target humidity (5300). For example, the control unit 300 may determine whether the driving of the air supply device 80 has ended by comparing the humidity inside the tub 12 with the preset target humidity. For example, the humidity inside the tub 12 may be measured by the humidity sensor 700.

[0427] After the driving of the air supply device 80 starts (5100) and a preset time t4 has passed ("Yes" in 5200), when the humidity inside the drum 12 reaches a preset target humidity, the dishwasher 1 can end the driving of the air supply device 80 (5400).

[0428] For example, when the humidity inside the barrel 12 is below the preset target humidity (“Yes” in 5300), the driving of the air supply device 80 can be terminated (5400). For example, when the humidity inside the barrel 12 is below the preset target humidity (“Yes” in 5300), the operation of the first air supply device 100 can be interrupted. For example, when the humidity inside the barrel 12 is below the preset target humidity (“Yes” in 5300), the operation of the second air supply device 200 can be interrupted.

[0429] When the air supply device 80 starts to be driven (5100) and a preset time t4 has passed ("Yes" at 5200), if the humidity inside the drum 12 does not reach the preset target humidity, the dishwasher 1 can control the air supply device 80 to improve the drying performance.

[0430] For example, when the humidity inside the barrel 12 does not reach below the preset target humidity (“No” in 5300), the rotation speed of the air supply device 80 can be adjusted (5500). For example, the control unit 300 can control the air supply force of the air supply device 80 to be increased than before. For example, the control unit 300 can control the rotation speed of the air supply device 80 to be increased than before. For example, when the humidity inside the barrel 12 is not below the preset target humidity (“No” in 5300), the control unit 300 can increase the rotation speed of the first air supply device 100. For example, when the humidity inside the barrel 12 is not below the preset target humidity (“No” in 5300), the control unit 300 can increase the rotation speed of the second air supply device 200.

[0431] For example, after the rotation speed of the air supply device 80 is adjusted (5500), when a preset time t5 has passed ("Yes" in 5600), the driving of the air supply device 80 can be terminated (5400).
