The 2a discharge unit 246a may be arranged spaced apart in the -X axis direction compared to the 2b discharge unit 246b.

[0112] The 2a discharge unit 246a and the 2b discharge unit 246b may discharge air in the same direction as each other.

[0113] For example, the 2a discharge unit 246a, the 2b discharge unit 246b, or both the 2a discharge unit 246a and the 2b discharge unit 246b may be configured to discharge air toward the inside of the tub 12.

[0114] For example, the 2a discharge unit 246a, the 2b discharge unit 246b, or both the 2a discharge unit 246a and the 2b discharge unit 246b may be configured to discharge air in the -Z axis direction.

[0118] The second air supply device 200 may include a 2b flow path 222. The air inhaled through the second suction unit 236 may flow along the 2b flow path 222 and be discharged into the tub 12 through the 2b discharge unit 246b of the 2b discharge cap 240b. The 2b flow path 222 may have a curved shape to reduce the flow loss of the air flowing on the 2b flow path 222.

[0119] The 2a flow path 221 and the 2b flow path 222 may be provided in a divided manner.

[0120] The first air supply device 100, the second air supply device 200, or both the first air supply device 100 and the second air supply device 200 may be provided to operate during the drying process. The first air supply device 100, the second air supply device 200, or both the first air supply device 100 and the second air supply device 200 may be provided to operate in a state where the door 11 opens the opening 12a of the tub 12.

[0121] The first air supply device 100, the second air supply device 200, or both the first air supply device 100 and the second air supply device 200 may be provided to discharge the water vapor inside the tub 12 to the outside of the tub 12 through the opening 12a of the tub 12 in a state where the door 11 opens the opening 12a of the tub 12. Accordingly, the moisture inside the tub 12 can be reduced.

[0122] The first air supply device 100, the second air supply device 200, or both the first air supply device 100 and the second air supply device 200 may be provided to circulate the air inside the tub 12 in a state where the door 11 opens the opening 12a of the tub 12. Accordingly, the average flow velocity of the air inside the tub 12 can be increased. The air inside the tub 12 can be uniformly mixed.

[0123] The dishwasher may perform a washing process of washing tableware using water and detergent, a rinsing process of rinsing the tableware, and a drying process of removing the moisture remaining on the tableware.

[0124] Generally, as an example, when the dishwasher performs the drying process, a dehumidifying agent may be used to remove the water vapor inside the tub. As the dehumidifying agent absorbs the water vapor, the inside of the tub can be dried. However, in order to reuse the dehumidifying agent, a process of heating the dehumidifying agent to evaporate the water contained in the dehumidifying agent may be required. As an example, the dishwasher may supply hot air to the inside of the tub during the drying process. As an example, the dishwasher may heat the washing water for condensation drying during the final rinsing process before the drying process. In order to heat the dehumidifying agent, supply hot air, and / or heat the washing water, a heater may be used. When the heater operates, the energy consumption of the dishwasher may increase.

[0125] In contrast, the dishwasher 1 can effectively perform the drying process by the first air supply device 100, the second air supply device 200, or both the first air supply device 100 and the second air supply device 200, without the need for a separate heater. For example, during the drying process, the dishwasher 1 can continuously circulate the air inside the tub 12 while discharging the water vapor inside the tub 12 to the outside of the tub 12, thereby effectively evaporating the moisture remaining inside the tub 12. Also, the dishwasher 1 can improve the drying efficiency by activating the flow field inside the tub 12. Therefore, the dishwasher 1 can perform an effective drying process without a heater. And, compared with the above example, the dishwasher 1 omits the heating process by the heater, thus being able to save energy.

[0126] For example, during the drying process of the dishwasher 1, the door 11 can open the opening 12a of the tub 12 by a predetermined range. The drying process of the dishwasher 1 can be carried out by a condensation drying process, a natural convection drying process, and a forced convection drying process. After the start of the drying process, the condensation drying can be carried out for a predetermined time (t1). The condensation drying can be carried out by condensing the water droplets inside the tub 12 with the door 11 closing the opening 12a. After a predetermined time (t1) has elapsed since the start of the drying process, the door 11 can be opened. After the door 11 opens the opening 12a, the natural convection drying can be carried out for a predetermined time (t2). The natural convection drying can be carried out by allowing the air outside the tub 12 to flow into the tub 12 with the door 11 opening the opening 12a. It can be configured such that after the door 11 opens the opening 12a and a predetermined time (t2) has elapsed, the air supply device 80 operates.

[0127] After the start of the drive of the air supply device 80, the forced convection drying can be carried out for a predetermined time (t3). In the forced convection drying, with the door 11 opening the opening 12a, as the air supply device 80 generates an air supply force, a forced convection can be generated. For example, the first air supply device 100 can be configured to discharge the water vapor inside the tub 12 to the outside of the tub 12. For example, the second air supply device 200 can be configured to form a circulating air flow inside the tub 12.

[0128] For example, the air discharged through the 1a discharge portion 146a is discharged toward the opening 12a, so that the water vapor inside the tub 12 can be smoothly discharged to the outside of the tub 12. That is, the water vapor inside the tub 12 can be discharged to the outside of the tub 12 through the opening 12a by the air discharged to the 1a discharge portion 146a.

[0129] The air discharged through the first discharge part 146b can be discharged toward the lower side part of the tub 12, so as to be concentratedly blown toward the part where the drying performance is relatively reduced. The air discharged through the first discharge part 146b can be discharged into the tub 12 to form a circulating air flow inside the tub 12. Thus, the air inside the tub 12 can be uniformly mixed.

[0130] The air discharged through the second discharge part 246a and / or the second discharge part 246b is discharged toward the lower side part of the tub 12, so that it can be concentratedly blown toward the part where the drying performance is relatively reduced. The air discharged through the second discharge part 246a, the second discharge part 246b, or the second discharge part 246a and the second discharge part 246b can be discharged into the tub 12 to form a circulating air flow inside the tub 12. Thus, the air inside the tub 12 can be uniformly mixed.

[0131] That is, the first discharge part 146a, the first discharge part 146b, the second discharge part 246a, and the second discharge part 246b can be arranged at different positions from each other, so as to diversely guide the moving direction of the air inside the tub 12.

[0132] The first discharge part 146a, the first discharge part 146b, the second discharge part 246a, and the second discharge part 246b can diversely guide the direction of the discharged air.

[0191] The second air supply device 200 may include a second discharge cap 240. The second discharge cap 240 may be configured to connect the second air supply duct 220 to the interior of the tub 12. The second discharge cap 240 may be detachably mounted on the inner wall of the second side 12c of the tub 12. The second discharge cap 240 may be configured to communicate with the second row of outlets 2252, 2253 of the second air supply duct 220.

[0192] The second discharge cap 240 may include a 2a discharge cap 240a. The 2a discharge cap 240a may be configured to communicate with the 2a row of outlets 2252. The 2a discharge cap 240a may include a 2a guiding hole 247a corresponding to the 2a guiding protrusion 2272.

[0194] A detailed description of the second discharge cap 240 will be provided later with reference to Figures 11 to 15 the description.

[0195] Figure 9 is a view showing a case where an inhalation cover of a dishwasher according to an embodiment of the present disclosure is coupled to a duct. Figure 10 is along Figure 1 an enlarged cross-sectional view of the dishwasher taken along line B-B' of.

[0196] Hereinafter, for convenience, the first air supply device 100 will be described as an example. That is, the first air supply duct 120, the first suction port 1251, and the first suction cover 130 will be described as examples, but this can also be equally applicable to the second air supply duct 220, the second suction port 2251, and the second suction cover 230 of the second air supply device 200.

[0197] That is, the second suction cover 230 may have the same shape and configuration as the first suction cover 130. The descriptions of the main body portion 131, the protruding portion 132, the suction guiding rib 133, the discharge hole 135, and the duct coupling portion 142 of the first suction cover 130 can also be equally applicable to the main body portion 231, the protruding portion 232, the suction guiding rib 233, the discharge hole 235, and the duct coupling portion 242 of the second suction cover 230 (refer to Figure 7 and Figure 8 ).

[0198] The second suction cover coupling portion 2261 of the second air supply duct 220 may have the same shape and configuration as the first suction cover coupling portion 1261 of the first air supply duct 120.

[0199] The first suction cover 130 may include a main body portion 131. The main body portion 131 may be configured to cover the first suction port 1251.

[0200] The main body portion 131 may be configured to cover the first air supply fan 110. The main body portion 131 may prevent at least one of foreign matters in the tub 12 or wash water from flowing into the first air supply fan 110. For example, the main body portion 131 may prevent wash water from penetrating into the first air supply fan 110 during the washing stroke and / or the rinsing stroke. For example, it may prevent foreign matters (e.g., food residues, etc.) inside the tub 12 from penetrating into the first air supply fan 110. Thereby, damage to the first air supply fan 110 can be prevented, and thus the life of the first air supply fan 110 can be extended.

[0201] The first suction cover 130 may include a protruding portion 132. The protruding portion 132 may protrude from the main body portion 131 toward the inside of the tub 12. The protruding portion 132 may be configured to ensure the size of the suction portion 136. The protruding portion 132 may minimize the suction pressure by ensuring a space between the first air supply fan 110 and the first suction portion 136.

[0202] The first suction cover 130 may include a suction guiding rib 133. The suction guiding rib 133 may be formed on the side of the main body portion 131 facing the first suction port 1251.

[0203] The intake guide rib 133 can be configured to guide air to the first blower fan 110. The intake guide rib 133 can have an inclined shape. For example, the intake guide rib 133 can include a downwardly inclined shape. For example, the intake guide rib 133 can include a curved shape.

[0204] The intake guide rib 133 can prevent wash water from flowing into the first intake port 1251. For example, the intake guide rib 133 can guide the wash water flowing into the first intake cover 130 to below between the inner wall of the tub 12 and the first intake cover 130. Thus, the wash water flowing into the inside of the first intake cover 130 can flow downward without flowing into the first blower fan 110. The wash water guided by the intake guide rib 133 can be discharged to the tub 12 through the discharge hole 135.

[0205] The intake guide rib 133 can reduce the flow resistance of the air flowing toward the first blower fan 110. The air inhaled through the intake port 150 flows along the curved shape of the intake guide rib 133, so that it can move smoothly toward the first blower fan 110 side.

[0206] For example, the intake guide rib 133 can be configured as multiple. The multiple intake guide ribs 133 can be arranged spaced apart from each other. The multiple intake guide ribs 133 can be arranged in the vertical direction.

[0207] The first intake cover 130 can include a discharge hole 135. The discharge hole 135 can discharge the wash water flowing into the inside of the first intake cover 130. The discharge hole 135 can be formed at the lower end of the first intake cover 130. For example, the wash water guided by the intake guide rib 133 can flow downward naturally and be discharged to the inside of the tub 12 through the discharge hole 135.

[0208] The first intake cover 130 can include a discharge plate 137. The discharge plate 137 can be configured to guide the wash water flowing into the inside of the first intake cover 130 to the discharge hole 135.

[0209] The first intake cover 130 can be detachably coupled to the first intake port 1251. The pipe coupling portion 134 of the first intake cover 130 can be coupled to the first intake cover coupling portion 1261 of the first air supply pipe 120.

[0210] As the pipe coupling portion 134 rotates in a state corresponding to the first intake cover coupling portion 1261, the pipe coupling portion 134 can be fixed to the first intake cover coupling portion 1261. As the pipe coupling portion 134 rotates in a state fixed to the first intake cover coupling portion 1261, the pipe coupling portion 134 can be separated from the first intake cover coupling portion 1261.

[0211] The pipe coupling portion 134 of the first suction cap 130 may include a coupling protrusion 134a, a rotation guide groove 134b, and a reinforcing rib 134c. The reinforcing rib 134c may be provided to strengthen the rigidity of the coupling protrusion 134a. The reinforcing rib 134c may be configured to space at least a portion of the coupling protrusion 134a from the main body portion 131. A rotation guide groove 134b may be formed between the coupling protrusion 134a and the main body portion 131.

[0212] The first suction cap coupling portion 1261 of the first air supply pipe 120 may include a rotation guide rib 1261a and a support rib 1261b. The rotation guide rib 1261a may guide the coupling protrusion 134a to perform a rotational movement. The support rib 1261b may fix the coupling protrusion 134a when the coupling protrusion 134a reaches a predetermined position so that the coupling protrusion 134a no longer performs a rotational movement.

[0213] The first suction cap 130 may be integrally formed. The main body portion 131 and the pipe coupling portion 134 may be integrally formed. There is no need to separately manufacture a component for covering the first air supply fan 110 and a component for coupling the component to the first air supply pipe 120, so the number of components can be reduced, thereby improving manufacturing efficiency. Also, it is possible to prevent an increase in air resistance due to a narrowing of the suction area as the number of components increases.

[0214] Figure 11 FIG. is a view showing a case where a discharge cap of a dishwasher according to an embodiment of the present disclosure is coupled to a pipe. Figure 12 is along Figure 1 An enlarged cross-sectional view of the dishwasher taken along line C-C' of. Figure 13 FIG. is a view showing a case where a discharge cap of a dishwasher according to an embodiment of the present disclosure is coupled to a pipe. Figure 14 FIG. is a view showing a case where a discharge cap of a dishwasher according to an embodiment of the present disclosure is coupled to a pipe. Figure 15 FIG. is a view showing a case where a discharge cap of a dishwasher according to an embodiment of the present disclosure is coupled to a pipe. Figure 16 is along Figure 1 An enlarged cross-sectional perspective view of the dishwasher taken along line C-C' of.

[0215] Hereinafter, for convenience, the first air supply device 100 will be described as an example. That is, the description of the first air supply duct 120, the 1b row outlet 1253, and the first discharge cap 140 can also be equally applicable to the 1a row outlet 1252 of the first air supply device 100 and the second air supply duct 220, the 2a row outlet 2252, the 2b row outlet 2253, and the second discharge cap 240 of the second air supply device 200. Also, the description of the main body portion 131, the protruding portion 132, the suction guiding rib 133, the discharge hole 135, and the duct coupling portion 142 of the first suction cover 130 can also be equally applicable to the main body portion 231, the protruding portion 232, the suction guiding rib 233, the discharge hole 235, and the duct coupling portion 242 of the second suction cover 230 (see Figure 7 and Figure 8 ).

[0216] That is, the 1a discharge cap 140a, the 1b discharge cap 140b, the 2a discharge cap 240a, and the 2b discharge cap 240b can have substantially the same shape. Except for the coupling position, the 1a discharge cap 140a, the 1b discharge cap 140b, the 2a discharge cap 240a, and the 2b discharge cap 240b can be substantially the same. That is, since the 1a discharge cap 140a, the 1b discharge cap 140b, the 2a discharge cap 240a, and the 2b discharge cap 240b are substantially the same, there is no need to provide separate discharge caps that differ according to the air discharge direction, thus saving components and improving manufacturing efficiency.

[0217] The 1a discharge cap coupling portion 1257 of the first air supply duct 120, the 2a discharge cap coupling portion 2257, and the 2b discharge cap coupling portion 2258 of the second air supply duct 220 can have the same shape and configuration as the 1b discharge cap coupling portion 1258 of the first air supply duct 120.

[0218] The discharge cap 140 can include discharge guiding ribs 141. The discharge guiding ribs 141 can be provided in plurality. The plurality of discharge guiding ribs 141 can be arranged at intervals from each other. A discharge portion 146 can be formed between the plurality of discharge guiding ribs 141.

[0219] The discharge guiding ribs 141 can be arranged obliquely to guide the air discharge direction. Depending on the installation position of the discharge cap 140, the direction in which the discharge guiding ribs 141 are inclined can be different, and accordingly, the direction of the air discharged through the discharge portion 146 can be different.

[0220] The discharge cap 140 can include drain holes 143. The drain holes 143 can discharge the washing water flowing into the interior of the discharge cap 140. The drain holes 143 can be formed along the circumference of a circle. The drain holes 143 can include at least one hole. The drain holes 143 can be formed through the discharge cap 140.

[0221] The air supply duct 120 may include a bent portion 127. The second housing 120b may include the bent portion 127. The bent portion 127 may be configured to guide the direction of the air discharged through the discharge portion 146. The bent portion 127 may be configured to reduce noise caused by the flow of air by guiding the direction of the air.

[0222] The bent portion 127 may include an inclined surface. The bent portion 127 may include a curved surface. The bent portion 127 may be formed to be inclined toward the discharge portion 146.

[0223] The air supply duct 120 may include a spaced-apart space 126 configured to form a gap. The spaced-apart space 126 may be a space formed between the bent portion 127 and the duct coupling portion 1258. The spaced-apart space 126 may be configured to prevent foreign substances flowing into the air supply duct 120 from the tub 12 from getting stuck inside the air supply duct 120.

[0224] Specifically, in the case where foreign substances inside the tub 12 flow into the inside of the air supply duct 120, the foreign substances may accumulate in the spaced-apart space 126 of the air supply duct 120 according to the flow of air and / or washing water. At this time, by reducing the size of the spaced-apart space 126, the foreign substances accumulated in the spaced-apart space 126 can be easily discharged to the outside of the air supply duct 120. That is, even if foreign substances accumulate in the spaced-apart space 126, in the case where the washing water flowing in from the tub 12 reaches the spaced-apart space 126, the foreign substances accumulated in the spaced-apart space 126 can also be easily discharged to the outside of the air supply duct 120 together with the washing water. Therefore, the phenomenon of foreign substances getting stuck in the spaced-apart space 126 can be prevented.

[0225] The discharge cap 140 may be detachably coupled to the discharge port 1253. The duct coupling portion 142 of the discharge cap 140 may be coupled to the discharge cap coupling portion 1258.

[0226] As the duct coupling portion 142 rotates in a state corresponding to the discharge cap coupling portion 1258, the duct coupling portion 142 may be fixed to the discharge cap coupling portion 1258. As the duct coupling portion 142 rotates in a state fixed to the discharge cap coupling portion 1258, the duct coupling portion 142 may be separated from the discharge cap coupling portion 1258.

[0227] The discharge cap coupling portion 1258 may include coupling ribs 1263. The coupling ribs 1263 may be configured to correspond to the coupling protrusions of the duct coupling portion 142. The coupling ribs 1263 may include rotation guide ribs 1263a and support ribs 1263b. The rotation guide ribs 1263a may guide the rotational movement of the duct coupling portion 142. The support ribs 1263b may fix the duct coupling portion 142 when the duct coupling portion 142 reaches a predetermined position so that the duct coupling portion 142 no longer rotates.

[0228] The discharge cap coupling part 1258 may include a guide protrusion 1273. The guide protrusion 1273 may be configured to guide the coupling position of the discharge cap 140. The guide protrusion 1273 may be configured to guide the placement position of the discharge cap 140.

[0229] The discharge cap 140 may include a guide hole 147 configured to be capable of coupling to the guide protrusion 1273. The guide hole 147 may be formed to be larger than the guide protrusion 1273. The guide hole 147 may be formed to extend along the circumference of a circle. The guide hole 147 may be formed to penetrate through the discharge cap 140.

[0230] Refer to Figure 14 , the guide hole 147 of the discharge cap 140 may be aligned with the guide protrusion 1273 of the air supply duct 120 correspondingly.

[0231] The guide protrusion 1273 may be configured to protrude toward the inside of the tub 12. That is, the guide protrusion 1273 is formed to protrude toward the inside of the tub 12, so that the user can easily confirm the position of the guide protrusion 1273 with the naked eye. Therefore, the guide hole 147 of the discharge cap 140 can be easily coupled to the position corresponding to the guide protrusion 1273, and thus incorrect assembly of the discharge cap 140 can be prevented.

[0232] The first a discharge cap 140a, the first b discharge cap 140b, the second a discharge cap 240a, and the second b discharge cap 240b may variously guide the discharge direction of air according to the coupling position. The first a discharge cap 140a, the first b discharge cap 140b, the second a discharge cap 240a, and the second b discharge cap 240b may variously guide the discharge direction of air according to the placement position.

[0233] The first a guide protrusion 1272 disposed at the first a discharge port 1252 may guide the placement position of the first a discharge cap 140a. The first b guide protrusion 1273 disposed at the first b discharge port 1253 may guide the placement position of the first b discharge cap 140b. The second a guide protrusion 2272 disposed at the second a discharge port 2252 may guide the placement position of the second a discharge cap 240a. The second b guide protrusion 2273 disposed at the second b discharge port 2253 may guide the placement position of the second b discharge cap 240b.

[0234] As the first a discharge cap 140a, the first b discharge cap 140b, the second a discharge cap 240a, and the second b discharge cap 240b are respectively rotated and coupled in directions matching the first a discharge cap 140a, the first b discharge cap 140b, the second a discharge cap 240a, and the second b discharge cap 240b, the direction of the air discharged to the first a discharge cap 140a, the first b discharge cap 140b, the second a discharge cap 240a, and the second b discharge cap 240b may be different.

[0235] For example, the first discharge cap 140a can be coupled to the first discharge port 1252 to discharge air at an angle of about 45 degrees in the direction from the +X axis to the +Z axis. For example, the second discharge cap 140b can be coupled to the second discharge port 1253 to discharge air at an angle of about 30 degrees in the direction from the -Z axis to the -X axis.

[0236] For example, the second discharge cap 240a can be coupled to the second discharge port 2252 to discharge air at an angle of about 90 degrees in the direction toward the -Z axis. For example, the second discharge cap 240b can be coupled to the second discharge port 2253 to discharge air at an angle of about 90 degrees in the direction toward the -Z axis.

[0237] Referring to Figure 15 and Figure 16 After the guiding protrusion 1273 is inserted into the guiding hole 147, the discharge cap 140 can be rotated in the A direction. In this figure, the case where the A direction is counterclockwise is illustrated as an example, but the present disclosure is not limited thereto. The A direction can also be clockwise. As the discharge cap 140 rotates, the pipe coupling portion 142 of the discharge cap 140 can be fixed to the discharge cap coupling portion 1258 of the air supply pipe 120.

[0238] The user can correspondingly couple the guiding hole 147 of the discharge cap 140 with the guiding protrusion 1273 of the air supply pipe 120, so that the direction can be conveniently set when assembling the discharge cap 140. The guiding protrusion 1273 can guide the user to assemble the discharge cap 140 in the correct direction. The guiding protrusion 1273 can be provided to prevent the wrong assembly of the discharge cap 140.

[0239] Figure 17 is a view showing the air flow of a dishwasher according to an embodiment of the present disclosure.

[0240] The air supply device 80 can perform the drying process of the dishwasher 1. When the door 11 of the dishwasher 1 opens the opening 12a of the tub 12 by a predetermined range, the air outside and / or inside the tub 12 is sucked through the first suction portion 136, the second suction portion 236, or the first suction portion 135 and the second suction portion 236.

[0241] The air sucked into the first suction portion 136 can be discharged through the first discharge portion 146a, the second discharge portion 146b, or the first discharge portion 146a and the second discharge portion 146b. The first discharge portion 146a and the second discharge portion 146b can be arranged at intervals in the vertical direction, the horizontal direction, or the vertical direction and the horizontal direction. The air discharged through the first discharge portion 146a can move toward the outside of the tub 12.

According to the present disclosure, the discharge direction of the air can be adjusted according to the mounting position for the discharge cap 140 to be coupled. Therefore, the discharge direction of the air can be adjusted at multiple angles. According to the present disclosure, the discharge cap 140 can be easily coupled to the air supply duct 120.

[0245] The discharge cap coupling parts 1257 and 1258 may include guide protrusions 1272 and 1273 protruding toward the discharge cap 140 to guide the first or second installation position of the discharge cap 140. The guide protrusions 1272 and 1273 include: a first guide protrusion 1272 provided at the first discharge port 1252 to guide the first installation position of the discharge cap 140; and a second guide protrusion 1273 provided at the second discharge port 1253 to guide the second installation position of the discharge cap 140. According to the present disclosure, the installation position where the discharge cap 140 is coupled can be easily guided.

[0246] The discharge cap 140 may include guide holes 147 configured to be coupled to the guide protrusions 1272 and 1273. The guide holes 147 may be configured to be larger than the guide protrusions 1272 and 1273 so that the discharge cap 140 is rotatably coupled to the discharge ports 1252 and 1253. According to the present disclosure, by rotating the discharge cap 140, it can be easily coupled to the air supply duct 120.

[0247] The discharge cap coupling parts 1257 and 1258 may include coupling protrusions 1262 and 1263 configured to fix the discharge cap 140 coupled to the discharge ports 1252 and 1253. According to the present disclosure, the discharge cap 140 can be firmly fixed to the discharge ports 1252 and 1253 to prevent the discharge cap 140 coupled to the discharge ports 1252 and 1253 by rotation from coming off.

[0248] The discharge cap 140 may include drain holes 143 configured to drain water. According to the present disclosure, the water inside the air supply duct 120 can be easily drained.

[0249] The discharge cap 140 may include discharge guide ribs 141 formed obliquely to guide the discharge direction of air. The discharge guide ribs 141 may be configured to discharge air in a first direction when the discharge cap 140 is in the first installation position, and configured to discharge air in a second direction different from the first direction when the discharge cap 140 is in the second installation position. According to the present disclosure, the discharge direction of air can be different according to the arrangement direction of the discharge guide ribs 141.

[0250] The dishwasher 1 may further include a suction cover 130 that can be coupled to the suction port 1251 so as to cover the suction fan 110. According to the present disclosure, the suction fan 110 can be protected from foreign objects and / or washing water.

[0251] The air supply duct 120 may include a suction lid coupling part 1261 configured to enable the suction lid 130 to be coupled to the suction port 1251.
