second blower 200 may include asecond outlet 260. Thesecond blower 200 may discharge air sucked through thesecond inlet 250 to the inside of thetub 12 through thesecond outlet 260. At least onesecond outlet 260 may be provided. - For example, a plurality of
second outlets 260 may be provided. For example, thesecond outlet 260 may include a 2a-th outlet 261 and a 2b-th outlet 262. The 2a-th outlet 261 and the 2b-th outlet 262 may discharge air in the same direction, although not limited thereto. However, the 2a-th outlet 261 and the 2b-th outlet 262 may discharge air in different directions. - The
second blower 200 may form a flow path along which inside air of thetub 12 flows. - The
second blower 200 may include afirst flow path 221. For example, air sucked through thesecond inlet 250 may flow along thefirst flow path 221 and then be discharged to the inside of thetub 12 through the 2a-th outlet 261. For example, thefirst flow path 221 may have a curved shape to reduce a flow loss of air flowing on thefirst flow path 221. - The
second inlet 250 may be provided at upstream of thefirst flow path 221 in a flow direction of air. Thesecond outlet 260 may be provided at downstream of thefirst flow path 221 in the flow direction of air. The 2a-th outlet 261 may be provided at the downstream of thefirst flow path 221 in the flow direction of air. - The
second blower 200 may include asecond flow path 222. For example, thesecond flow path 222 may be partitioned from thefirst flow path 221. For example, air sucked through thesecond inlet 250 may flow along thesecond flow path 222 and then be discharged to the inside of thetub 12 through the 2b-th outlet 262. For example, thesecond flow path 222 may have a curved shape to reduce a flow loss of air flowing on thesecond flow path 222. - The

first blower 100 may operate during a drying operation. Thefirst blower 100 may operate while thedoor 11 opens the opening 12 a of thetub 12. - The
second blower 200 may operate during a drying operation. Thesecond blower 200 may operate while thedoor 11 opens the opening 12 a of thetub 12. - At least one of the
first blower 100 or thesecond blower 200 may discharge inside vapor of thetub 12 to the outside of thetub 12 through the opening 12 a of thetub 12 while thedoor 11 opens the opening 12 a of thetub 12. Thereby, inside humidity of thetub 12 may be lowered. - At least one of the
first blower 100 or thesecond blower 200 may circulate inside air of thetub 12 while thedoor 11 opens the opening 12 a of thetub 12. Thereby, an average flow velocity of inside air of thetub 12 may increase. Inside air of thetub 12 may be mixed thoroughly. - Generally, for example, a dishwasher may use a dehumidifying agent to remove inside vapor of a tub during a drying operation. Because the dehumidifying agent absorbs vapor, the inside of the tub may be dried. However, to use a dehumidifying agent, a process of heating the dehumidifying agent to evaporate water included in the dehumidifying agent may be needed. For example, the dishwasher may provide hot air to the inside of the tub during a drying operation. For example, during a final rinsing operation before a drying operation, the dishwasher may heat washing water for condensation drying. A heater may be used to heat a dehumidifying agent, provide hot air, and/or heat washing water. According to an operation of the heater, energy consumption of the dishwasher may increase.
- Compared to this, the
dishwasher 1 may effectively perform a drying operation through thefirst blower 100 and/or thesecond blower 200 without including a separate heater. For example, thedishwasher 1 may effectively evaporate water remaining inside thetub 12 during a drying operation by discharging inside vapor of thetub 12 to the outside of thetub 12 while continuously circulating inside air of thetub 12. Also, thedishwasher 1 may improve drying efficiency by activating an inner flow field of thetub 12. Thereby, thedishwasher 1 may effectively perform a drying operation without a heater. Compared to the above-described examples, thedishwasher 1 may save energy by omitting a heating process by a heater. -

For example, thefirst blow fan 110 may generate a discharge force such that air entered thefirst blower 100 is discharged to thetub 12. Thefirst blow fan 110 may also be referred to as afirst fan 110. Since thefirst blow fan 110 may be arranged in a side of the tub, and as illustrated inFIG. 10 thefirst blow fan 110 may be arranged on an outer side of thetub 12, and therefore may be described as being arranged at the side of thetub 12. - For example, the
first blow fan 110 may be an axial flow fan, a mixed flow fan, or a centrifugal fan. However, a kind of thefirst blow fan 110 is not limited to these, and thefirst blow fan 110 may have any configuration capable of generating a blowing force to suck inside air of thetub 12 and then discharge the air to thetub 12. - For example, the

tub 12, and the upper portion of thedoor 11 may be rotatable on the lower portion of thedoor 11 with respect to thetub 12. For example, the 1a-th outlet 161 may be adjacent to theopening 12 a. For example, the 1a-th outlet 161 may be positioned in front of thefirst inlet 150. The 1a-th outlet 161 may be positioned at a front, upper portion of thefirst side 12 b of thetub 12. The 1a-th outlet 161 may discharge air guided by thefirst blow duct 120 toward the opening 12 a to thus smoothly discharge inside vapor of thetub 12 to the outside of thetub 12. Thereby, inside humidity of thetub 12 may be lowered. - For example, the
first outlet 160 may include the 1b-th outlet 162 through which air flowing on thesecond flow path 122 is discharged. The 1b-th outlet 162 may be provided at another side of thesecond flow path 122.

Accordingly, the lower portion of thetub 12 may have lower drying efficiency than the upper portion of thetub 12. For example, the 1b-th outlet 162 may be positioned relatively away from the opening 12 a, compared to the 1a-th outlet 161. For example, the 1b-th outlet 162 may be positioned below the 1a-th outlet 161. For example, the 1b-th outlet 162 may be positioned below thefirst inlet 150.

Air discharged through the 2a-th outlet 261 may flow away from the opening 12 a. - For example, the opening 12 a may be formed in the front side of the
tub 12, and the upper portion of thedoor 11 may be rotatable on the lower portion of thedoor 11 with respect to thetub 12. During a drying operation, thedoor 11 may open the opening 12 a to a preset range. At this time, the upper portion of thetub 12 may be exposed to the outside of thetub 12 through the opening 12 a, and the lower portion of thetub 12 may be covered by thedoor 11 not to be exposed to the outside of thetub 12. Accordingly, the lower portion of thetub 12 may have lower drying efficiency than the upper portion of thetub 12. For example, the 2a-th outlet 261 may be positioned away from the opening 12 a. For example, the 2a-th outlet 261 may be positioned below thesecond inlet 250. The 2a-th outlet 261 may be positioned at a lower portion of thesecond side 12 c of thetub 12. The 2a-th outlet 261 may be positioned at a rear, lower portion of thesecond side 12 c of thetub 12.

second outlet 260 may include the 2b-th outlet 262 through which air flowing on thesecond flow path 222 is discharged. The 2b-th outlet 262 may be provided at another side of thesecond flow path 222. The 2b-th outlet 262 may be formed by the 2b-th outlet cap 242. Air discharged through the 2-th outlet 262 may flow away from the opening 12 a. - For example, the opening 12 a may be formed in the front side of the
tub 12, and the upper portion of thedoor 11 may be rotatable on the lower portion of thedoor 11 with respect to thetub 12. During a drying operation, thedoor 11 may open the opening 12 a to a preset range. At this time, the upper portion of thetub 12 may be exposed to the outside of thetub 12 through the opening 12 a, and the lower portion of thetub 12 may be covered by thedoor 11 not to be exposed to the outside of thetub 12. Accordingly, the lower portion of thetub 12 may have lower drying efficiency than the upper portion of thetub 12. For example, the 2b-th outlet 262 may be positioned below thesecond inlet 250. For example, the 2b-th outlet 262 may be positioned in the front-rear direction with respect to the 2a-th outlet 261. For example, the 2b-th outlet 262 may be positioned in front of the 2a-th outlet 261. The 2b-th outlet 262 may be positioned at the lower portion of thesecond side 12 c of thetub 12. The 2b-th outlet 262 may intensively blow air toward the portion having relatively low drying performance. As a result, drying efficiency of thedishwasher 1 may be improved. - For example, the 2b-
th outlet cap 242 may be a substantially same as the 2a-th outlet cap 241 except for a location. For example, the 2b-th outlet 262 may be a substantially same as the 2a-th outlet 261 except for a location. Thesecond blower 200 may intensively blow air toward the lower portion of thetub 12 through the 2a-th outlet 261 and the 2b-th outlet 262. Thereby, drying efficiency at the lower portion of thetub 12 may be improved. Dishes located at the lower portion of thetub 12 may be effectively dried. - The
second blower 200 may include a sealingmember 271. The sealingmember 271 may prevent air entered thesecond blow duct 220 from being discharged between thesecond blow duct 220 and thetub 12.

FIGS. 17 and 18 . - During a drying operation, the
door 11 may open the opening 12 a of thetub 12 to a preset range (seeFIG. 2 ). Thesecond blower 200 may operate while thedoor 11 opens the opening 12 a of thetub 12 to the preset range. Thesecond blow fan 210 may generate a blowing force by rotating. Inside air of thetub 12 may pass through thesecond inlet cap 230 and enter the inside of thesecond blow duct 220 by the blowing force of thesecond blow fan 210. The air entered the inside of thesecond blow duct 220 may flow along the flow path formed inside thesecond blow duct 220. A part of the air entered the inside of thesecond blow duct 220 may flow along thefirst flow path 221. A remaining part of the air entered the inside of thesecond blow duct 220 may flow along thesecond flow path 222 partitioned from thefirst flow path 221. - Air guided by the
first flow path 221 may pass through the 2a-th outlet cap 241 and be discharged to the inside of thetub 12. Air guided by thefirst flow path 221 may be guided away from the opening 12 a by the 2a-thoutlet guide rib 2411 of the 2a-th outlet cap 241. Air discharged through the 2a-th outlet cap 241 may be discharged to the inside of thetub 12 to form a circulating airflow inside thetub 12. Accordingly, inside air of thetub 12 may be mixed thoroughly. - Air guided by the
second flow path 222 may pass through the 2b-th outlet cap 242 and then be discharged to the inside of thetub 12. Air guided by thesecond flow path 222 may be guided away from the opening 12 a by the 2b-thoutlet guide rib 2421 of the 2b-th outlet cap 242.

FIG. 34 shows an example of an operation cycle of a dishwasher according to an embodiment of the disclosure and an example of an operation cycle of a dishwasher according to a comparative example. - Generally, a dishwasher may perform a washing operation of washing dishes with water and a detergent, a rinsing operation of rinsing the dishes, and a drying operation of removing water remaining on the dishes. The rinsing operation may be configured with a primary rinsing operation for removing a detergent remaining on dishes during a washing operation and a secondary rinsing operation for finally rinsing the dishes after draining water used during the primary rinsing operation.
- Referring to an example of an operation cycle of a dishwasher according to a comparative example, a task for heating washing water by operating a heater during a secondary rinsing operation may be performed. By heating washing water during a secondary rinsing operation to spray high-temperature washing water to dishes, inside temperature of a tub may rise to facilitate evaporation of water remaining on the dishes. Through condensation drying and natural convection drying by opening a door after secondary rinsing, a drying operation may be performed. The dishwasher according to the comparative example may require great energy for a process of heating washing water during secondary rinsing. Accordingly, the dishwasher may have low energy efficiency. Also, there may be difficulties in effectively removing water remaining inside the tub and on the dishes only through condensation drying and natural convection drying. For example, a drying time of the dishwasher may increase. For example, remaining water resulting from ineffective drying of the dishwasher may cause contamination, a mold, damage to components, etc.
- Referring to an example of an operation cycle of the
dishwasher 1 according to an embodiment of the disclosure, a task of heating washing water during a secondary rinsing operation may be omitted.

For example, thedishwasher 1 may include thefirst blower 100 and thesecond blower 200. For example, thedishwasher 1 may easily discharge inside vapor of thetub 12 to the outside of thetub 12, while circulating inside air of thetub 12 to intensively blow air toward a portion having low drying efficiency. In summary, thedishwasher 1 may save energy that is consumed to heat washing water during a secondary rinsing operation. Also, thedishwasher 1 may effectively remove water remaining inside thetub 12 and on dishes through forced convection drying. Thedishwasher 1 may increase drying efficiency by causing forced convection inside thetub 12. -
