[0058] Figure 1 is a cross-sectional view of a dishwasher according to a first embodiment of the present disclosure, Figure 2 is a perspective view of a dishwasher according to a first embodiment of the present disclosure, Figure 3 is an exploded perspective view of some components of a dishwasher according to a first embodiment of the present disclosure, and Figure 4 is a side view of some components of a dishwasher according to a first embodiment of the present disclosure.

[0059] like Figure 1 and Figure 2 As shown, the dishwasher 1 may include a body 10 forming an exterior thereof.

[0060] The dishwasher 1 may further include a tub 12 disposed in the main body 10. The tub 12 may be configured in a substantially box shape. One side of the tub 12 may be openable. That is, the tub 12 may have an opening 12a. As an example, the front surface of the tub 12 may be openable.

[0061] The dishwasher 1 may further include a door 11 configured to open and close the opening 12a of the tub 12. The door 11 may be installed in the body 10 to open and close the opening 12a of the tub 12. The door 11 may be installed in the body 10 so as to rotate.

[0062] The dishwasher 1 may further include a storage container disposed in the tub 12 to accommodate tableware.

[0063] The storage container may include a plurality of baskets 51, 52, and 53. Relatively large tableware may be stored in the plurality of baskets 51 and 52. However, the types of tableware accommodated in the plurality of baskets 51, 52, and 53 are not limited to relatively large tableware. That is, the plurality of baskets 51, 52, and 53 may accommodate not only relatively large tableware but also relatively small tableware.

[0064] The plurality of baskets 51, 52, and 53 may include a middle basket 52 located in the middle of the height of the dishwasher 1 and a lower basket 51 located in the lower portion of the height direction of the dishwasher 1. The middle basket 52 may be provided to be supported by the middle guide rack 13a, and the lower basket 51 may be provided to be supported by the lower guide rack 13b. The middle guide rack 13a and the lower guide rack 13b may be mounted on the side surface 12d of the tub 12 so as to be slidable toward the opening 12a of the tub 12. The side surface 12d of the tub 12 may be a concept including the inner surface of the right wall and the inner surface of the left wall of the tub 12.

[0065] The storage container may include an upper basket 53 located at the upper part of the height of the dishwasher 1. The upper basket 53 may be formed in the rack assembly to accommodate relatively small tableware. Suitably, the upper basket 53 may contain cooking utensils, such as spoons, knives or turners, or cutlery. In addition, the rack assembly may accommodate small cups, such as espresso cups. However, the types of tableware accommodated in the upper basket 53 are not limited to the above examples.

[0066] In addition, the configuration of the basket is not limited thereto, and thus the upper basket 53 may not be included according to the size of the tub 12. Therefore, the storage container may be implemented with only the middle basket 52 and the lower basket 51.

[0067] The dishwasher 1 may further include a sump 70 configured to store wash water. The dishwasher 1 may include a washing chamber C corresponding to a space formed by the inside of the tub 12.

[0068] The washing chamber C is a space in which dishes placed in the baskets 51, 52, and 53 are washed by wash water and then dried.

[0069] The washing chamber C may be defined as an inner space of the tub 12 formed by the side surface 12d, the front and rear surfaces, the lower surface 12b of the tub, and the sump 70 connected to the lower surface 12b of the tub.

[0070] The dishwasher 1 may further include spray units 41, 42, and 43 configured to spray wash water. The spray units 41, 42, and 43 may include a first spray unit 41 disposed below the lower basket 51 in the height direction of the dishwasher 1, a second spray unit 42 disposed below the middle basket 52 in the height direction of the dishwasher 1, and a third spray unit 43 disposed above the upper basket 53 in the height direction of the dishwasher 1.

[0071] The first spray unit 41 may rotate around a rotation axis 41 a , the second spray unit 42 may rotate around a rotation axis 42 a , and the third spray unit 43 may rotate around a rotation axis 43 a .

[0072] However, the position of the spray unit is not limited to the first embodiment, and therefore, unlike the second spray unit 42 and the third spray unit 43, the first spray unit 41 may be fixed to one side of the lower surface 12b. In this case, the first spray unit 41 may be configured to spray wash water in a substantially horizontal direction through a fixed nozzle, and the wash water sprayed in a horizontal direction from the nozzle of the first spray unit 41 may be guided to the upper side because the direction of the sprayed water is changed by the switching assembly. The switching assembly may be mounted on the guide rail by a retainer and translated along the guide rail.

[0073] The third spray unit 43 may spray wash water toward the dishes stored in the upper basket 53 and the middle and lower baskets 52 and 51 , and the second spray unit 42 may spray wash water toward the dishes stored in the middle and upper baskets 52 and 53 .

[0074] Unlike the second and third spray units 42 and 43, the first spray unit 41 may be disposed on the lower surface 12b of the tub 12. In particular, the first spray unit 41 may be fixed to the sump 70.

[0075] The dishwasher 1 may include a circulation pump 30 configured to pump water stored in the sump 70 toward the spray units 41, 42, and 43. The wash water pumped by the circulation pump 30 may be supplied to the first spray unit 41 through an alternating device 80 connected to the circulation pump 30. Alternatively, the wash water pumped by the circulation pump 30 may move upward through a pipe 90 and then be supplied to the second spray unit 42 or the third spray unit 43.

[0076] As described above, wash water stored in the sump 70 or wash water introduced into the dishwasher 1 from the outside may flow toward the alternating device 80 through the circulation pump 30 .

[0077] The alternating device 80 may provide the wash water to the first spray unit 41 through the coupler 81 connected to the first spray unit 41 , and may provide the wash water to the pipe 90 through the flow path 62 connected to the pipe 90 .

[0078] The alternating device 80 may selectively supply wash water to at least one of the coupler 81 and the pipe 90 .

[0079] At least a portion of the coupler 81 and the flow path 62 may be disposed in the machine room L disposed below the washing chamber C, that is, at least a portion of the coupler 400 and the flow path 62 may be disposed lower than the lower surface 12b of the tub 12 with respect to the height direction of the dishwasher 1. Wash water may flow to the first spray unit 41 and the pipe 90 disposed in the washing chamber C through the coupler 81 and the flow path 62. Wash water may flow to the second spray unit 42 and the third spray unit 43 through the pipe 90.

[0080] like Figure 3 As shown, the dishwasher 1 may include a machine room L disposed below the tub 12. The machine room L may be formed by a lower frame 300. The machine room L may include a lower surface portion 310 forming a base of the dishwasher and a side surface portion 320 extending upward from the lower surface portion 310 and forming an inner space of the machine room L.

[0081] The side surface portion 320 may extend upward from the entire edge of the lower surface portion 310 to cover the entire side surface of the machine room L. Alternatively, as shown in FIG. Figure 3 As shown, the side surface portion 320 may extend upward from at least a portion of an edge of the lower surface portion 310 to form at least a portion of a side surface of the machine room L.

[0082] The above-mentioned circulation pump 30 and the sump 70 and the alternating device 80 may be disposed in the machine room L, and a water supply hose 210 and a drainage hose 100 to be described later may be disposed in the machine room L.

[0083] The dishwasher 1 may include a water supply hose 210 configured to supply wash water from the outside into the tub 12 .

[0084] One end 211 of the water supply hose 210 may be connected to the air brake assembly 220 configured to communicate with the tub 12, and the other end (not shown) of the water supply hose 210 may be connected to the outside by penetrating the lower frame 300 (see FIG. Figure 4 ).

[0085] Wash water may move from the other end (not shown) of the water supply hose 210 to the one end 211 and may be introduced into the tub 12 through the air brake assembly 220 .

[0086] The air brake assembly 220 may be configured to be in contact with the supply hole 12e formed on the side surface 12d of the tub 12 (see Figure 1 ) connected.

[0087] The air brake assembly 220 may supply wash water into the tub 12 through the water supply hose 210 .

[0088] The air brake assembly 220 may include an air hole 221. Through the air hole 221, external air may be introduced into the tub 12, or air in the tub 12 may be discharged to the outside.

[0089] The air brake assembly 220 may include a first hose fixing member 222 configured to fix at least a portion of the water supply hose 210. In addition, the air brake assembly 220 may include a second hose fixing member 223 configured to fix at least a portion of the drain hose 100 as will be described later.

[0090] The first hose fixing member 222 and the second hose fixing member 223 may be provided to fix the water supply hose 210 and the drain hose 100 to the air brake assembly 220 , respectively, without interference between the water supply hose 210 and the drain hose 100 .

[0091] The dishwasher 1 may include a drain hose 100 configured to drain wash water remaining in the tub 12 .

[0092] The drain hose 100 may be connected to the sump 70 to discharge wash water stored in the sump 70 to the outside of the dishwasher 1 .

[0093] As described above, the wash water collected in the sump 70 may be purified by the filter in the sump 70 and then circulated back into the washing chamber C through the circulation pump 30 .

[0094] However, when the wash water in the washing chamber C needs to be drained, the wash water collected in the washing chamber C and the sump 70 may be drained to the outside of the washing chamber C through the drain hose 100 .

[0095] The sump 70 may include a drain port (not shown) formed on one side of a sump in which wash water is collected.

[0096] The sump 70 may include a drain motor (not shown) configured to pump wash water to discharge the wash water collected in the sump 70 to the outside of the sump 70 through a drain port (not shown).

[0097] One end 111 of the drain hose 100 (corresponding to one end of the first drain hose 110 to be described later) can be connected to a drain outlet (not shown) of the storage tank 70, and the other end 132 of the drain hose 100 (corresponding to the other end of the second drain hose 130 to be described later) can be connected to the outside, so that the washing water remaining in the barrel 12 is discharged to the outside of the dishwasher 1.

[0098] That is, when the drain operation starts, the drain motor (not shown) may be driven, and the wash water collected in the sump 70 may be discharged to the drain port (not shown) and moved to the outside of the dishwasher 1 through the drain hose 100 connected to the drain port (not shown).

[0099] The drain hose 100 may include at least one section 100A. The at least one section 100A may be disposed at a position higher than the lower surface 12b of the tub 12 to prevent wash water from flowing back from the outside or to prevent wash water from moving inside the drain hose 100 during other operations other than the drain operation. The at least one section 100A may actually be disposed at a position higher than the wash water level in the washing chamber C. However, since the height of the wash water level in the washing chamber C corresponds to the approximate height of the lower surface 12b of the tub 12, the lower surface 12b of the tub 12 may be disposed as a reference for arranging the at least one section 100A of the drain hose 100.

[0100] Therefore, at least one section 100A of the drain hose 100 may be disposed to extend from the machine room L along the side surface 12 d of the tub 12 .

[0101] The arc section R may be formed on at least one section 100A of the drain hose 100. When the drain hose 100 extends from the machine room L to the side surface 12d of the tub 12, the arc section R may be naturally formed. The arc section R may be disposed above the lower surface 12b of the tub 12.

[0102] The arc section R may be formed with respect to the second hose fixing member 223. As described above, the arc section R is a section formed in such a manner that the drain hose 100 extends and is naturally arranged.

[0103] Regarding the direction in which the other end 132 of the drain hose 100 extends from the one end 111 of the drain hose 100 , the drain hose 100 may extend upward toward the second hose fixing member 223 , and then bend relative to the extending direction by the second hose fixing member 223 and extend downward.

[0104] In particular, the arc section R may be arranged in such a manner that one arc section R is formed between the one end 111 of the drain hose 100 and the second hose fixing member 223, and one arc section R is formed between the second hose fixing member 223 and the other end 132 of the drain hose 100, so that a total of two arc sections may be formed. However, the formation of the arc section R is not limited thereto, and thus a single arc section R may be formed between the one end 111 and the other end 132 of the drain hose 100 with respect to the second hose fixing member 223.

[0105] Alternatively, at least one section 100A of the drain hose 100 may include two bent portions perpendicular to each other without the arc section R. However, it is suitable to provide the arc section R to allow the wash water in the drain hose 100 to flow smoothly.

[0106] In a conventional manner, at least three fixing members are used to implement the disposition of the drain hose to be higher than at least a portion of the lower surface of the tub.

[0107] A conventional dishwasher includes a first fixing member, and second and third fixing members, wherein the first fixing member is configured to fix the top of the drain hose and corresponds to the second hose fixing member 223 according to the first embodiment of the present disclosure, and the second and third fixing members are configured to fix at least a portion of the drain hose extending from the opposite side of the first fixing member to the lower side.

[0108] Because in reality, the components configured to support each fixing member are not provided in the mechanical room, that is, since the lower frame 300 includes a lower surface portion 310 and a side surface portion 320 (such as the lower frame 300 according to the present disclosure) and it is not easy to support the fixing member, the fixing member fixes the drain hose by being connected to the side surface of the barrel.

[0109] At this time, as described above, at least three fixing members are required, thereby reducing the work efficiency of fixing the drain hose due to the fixing members and increasing the number of required parts.

[0110] In addition, all the fixing members are disposed on the side surface of the tub, and thus the fixing member disposed at the lowermost side among the fixing members is also disposed on the side surface of the tub. Therefore, the drain hose is disposed higher than the lower surface of the tub (which is more than necessary), and thus the drain hose extends upward. Therefore, the length of the drain hose increases more than the necessary length.

[0111] Furthermore, since the length of the drain hose is longer than necessary, the drain hose and the water supply hose may interfere with each other on the side surface of the tub, and may cause damage.

[0112] According to the first embodiment of the present disclosure, in order to alleviate the difficulty therein, the drain hose 100 may include a first coupling part 120 configured to be coupled to one side of the machinery room L. Hereinafter, the drain hose 100 and the first coupling part 120 of the drain hose 100 will be described in detail.

[0113] Figure 4 is a side view of some components of a dishwasher according to a first embodiment of the present disclosure, Figure 5 yes Figure 3 An enlarged stereogram of a portion of Figure 6 is a perspective view of some components of a dishwasher according to a first embodiment of the present disclosure.

[0114] like Figures 4 to 6 As shown, the drain hose 100 may include a first coupling part 120 provided on one side of the drain hose 100 .

[0115] The drain hose 100 may include a first drain hose 110 including a drain hose 110 connected to the sump 70 (see Figure 3 ) at one end 111 and the other end 112 connected to the first connecting member 120.

[0116] The first coupling member 120 may be provided in at least a portion of the drain hose 100 , and in particular, at one end of the first drain hose 110 .

[0117] The first coupling member 120 may also correspond to one part of the first drain hose 110 .

[0118] The drain hose 100 may include a second drain hose 130 including one end 131 connected to the other end 123 of the first coupling member 120 and the other end 132 connected to the outside.

[0119] The second drain hose 130 may include a middle portion 140 connected to the other end 123 of the first coupling member 120. In particular, the middle portion 140 may be connected to one end 131 of the second drain hose 130 and to the first coupling member 120.

[0120] The wash water stored in the sump 70 may be discharged to the outside of the dishwasher 1 through the first drain hose 110 , the first coupling part 120 , and the second drain hose 130 .

[0121] The second drain hose 130 may be a member extending to the outside of the dishwasher 1 , and thus, the second drain hose 130 may be commonly used in other devices such as a washing machine, a drying machine, and an air conditioner in addition to the dishwasher 1 .

[0122] The first drain hose 110 may be provided as a corrugated tube so as to be flexibly provided in the dishwasher 1. This is because the first drain hose 110 includes a section extending from the machine room L to the side surface 12d of the tub 12 as described later.

[0123] The other end 112 of the first drain hose 110 may be disposed to be inserted into the one end 122 of the first coupling member 120. The other end 112 of the first drain hose 110 and a section thereof adjacent to the other end 112 may be covered by the one end 122 of the first coupling member 120.

[0124] In particular, the first drain hose 110 may be provided to be inserted and injection-molded into the first coupling member 120. Therefore, the first drain hose 110 and the first coupling member 120 may be integrally formed with each other.

[0125] The first coupling member 120 may be configured to fix the drain hose 100 to one side of the machinery room L. Specifically, the first coupling member 120 may be connected to one side of the side surface portion 320 of the lower frame 300 . Therefore, the drain hose 100 may be supported by the side surface portion 320 .

[0126] The first drain hose 110 may be fixed to the second hose fixing member 223. In particular, a portion corresponding to the top of the first drain hose 110 may be fixed to the second hose fixing member 223.

[0127] The first drain hose 110 may include a second coupling part 113 configured to be fixed and connected to the second hose fixing member 223 .

[0128] The second hose fixing member 223 may be provided in a hook shape for the tube to be inserted. The second coupling part 113 may be provided as a region without corrugation so as to be easily inserted into the second hose fixing member 223 .

[0129] When in the drain hose 100, the point connected to the side surface portion 320 is defined as the first connection point C1 and the point connected to the second hose fixing member 223 is defined as the second connection point C2, the drain hose 100 according to the first embodiment of the present disclosure can be supported within the dishwasher 1 using only the first connection point C1 and the second connection point C2.

[0130] In a conventional manner, at least three coupling points need to be formed in the drain hose to couple the drain hose to the side surface of the tub. Therefore, at least three coupling parts configured to connect the drain hose to the side surface of the tub are required at the three coupling points.

[0131] However, according to an embodiment of the present disclosure, since the drain hose 100 includes the first coupling part 120 , an additional coupling point connected to the side surface 12 d of the tub 12 may not be required except for the second coupling point C2 connected to the second hose fixing member 223 .

[0132] Therefore, no additional component is required for connecting the drain hose 100 to the side surface 12d of the tub 12, and thus the connection structure of the drain hose 100 can be simplified. The first connection component 120 can be connected to one side of the machine room L in the vertical direction corresponding to the up-down direction Z, and the second connection component 113 can be connected to the tub 12 in the horizontal direction corresponding to the front-rear direction X.

[0133] As described above, the drain hose 100 may include a first connection point C1 and a second connection point C2, and the first connection point C1 and the second connection point C2 may be arranged in different directions. In particular, it is suitable that the first connection point C1 and the second connection point C2 may be connected to the side surface portion 320 and the side surface 12d of the tub 12 in directions perpendicular to each other.

[0134] Furthermore, when a section of the drain hose 100 forming a flow path on which wash water flows is defined as the hose body 101 , a portion of the hose body 101 disposed in the first coupling component 120 may be longer than a portion of the hose body 101 disposed in the second coupling component 113 .

[0135] The hose bodies 101 may be formed on the first drain hose 110 , the second drain hose 130 , and the first coupling part 120 , respectively.

[0136] Therefore, a portion of the hose body 101 connected in the up-down direction may be longer than a portion of the hose body 101 connected in the horizontal direction.

[0137] Only by using the second connection point C2 (which is connected to the tub 12 via the second hose fixing member 223), the drain hose 100 can be arranged to easily form the drain hose 100 formed at a position higher than the lower surface 12b of the tub 12 (when the drain hose 100 is connected to the tub 12 via the second hose fixing member 223). Figure 4 At least one section 100A (hereinafter referred to as the upper part 100A) at a water level B when the dishwasher 1 is driven in the middle.

[0138] Even when the point at which the drain hose 100 is connected to the inside of the dishwasher 1 is lower than a conventional point and the height H of the second coupling member 113 positioned at the top of the drain hose 100 is relatively low based on the water level B inside the dishwasher 1, the arc section R provided in the upper portion 100A can be easily formed. That is, as the fixing point is formed low, the point in the upper portion 100A that starts bending from the lower side is formed at a position lower than a conventional point.

[0139] Therefore, the drain hose 100 may have a smaller number of coupling points C1 and C2 than in a conventional manner, and the length of the drain hose 100 installed inside the dishwasher 1 may be shortened. The upper portion 100A may be formed on the first drain hose 110. As described above, when the first coupling member 120 is connected to the side surface portion 320 of the lower frame 300, the upper portion 100A may be formed between the first coupling member 120 and the one end 111 of the first drain hose 110.

[0140] As described above, since the first drain hose 110 is formed in the corrugated shape, the arc section R may be easily formed on the upper portion 100A.

[0141] The middle portion 140 may be connected to the other end 123 of the first coupling member 120. In particular, the other end 123 of the first coupling member 120 may be inserted into one end 141 of the middle portion 140.

[0142] The middle portion 140 serves as a component of the second drain hose 130 and a component configured to connect the first coupling member 120 to the second drain hose 130. The other end 142 of the middle portion 140 may be connected to one end 131 of the second drain hose 130.

[0143] However, the present disclosure is not limited thereto, and the middle portion 140 may be a separate component of the drain hose 100 from the second drain hose 130 .

[0144] The middle portion 140 may be formed of a material softer than the first coupling member 120. Therefore, the other end 123 of the first coupling member 120 may be easily inserted into the middle portion 140. That is, when the first coupling member 120 is formed of a plastic injection molding material, the middle portion 140 may be formed of a rubber material.

[0145] The middle portion 140 may be formed such that one end 141 and the other end 142 of the middle portion 140 open in directions perpendicular to each other. That is, by including a curved shape, the middle portion 140 may be configured such that one end 141 and the other end 142 point in directions perpendicular to each other.

[0146] In particular, when one end 141 of the middle portion 140 is disposed in the up-down direction Z, the other end 142 of the middle portion 140 may be disposed in the front-rear direction X or the left-right direction Y. This is to prevent the bending stress in the up-down direction Z from being transmitted to the first coupling member 120. This will be described in detail later.

[0147] Therefore, the other end 112 of the first drain hose 110 and the one end 131 of the second drain hose 130 may be arranged in directions perpendicular to each other.

[0148] As described above, one end 131 of the second drain hose 130 may be connected to the other end 142 of the middle portion 140. The other end 132 of the second drain hose 130 may be disposed outside through the penetration surface 325 of the side surface portion 320. In addition, the water supply hose 210 may be connected to the outside through the penetration surface 325.

[0149] The wash water stored in the dishwasher 1 may be drained through the other end 132 of the second drain hose 130 .

[0150] The first coupling member 120 may be connected to the side surface portion 320 in the up-down direction Z. As described later, the first coupling member 120 may include an insertion portion 125 inserted into a slit 322 vertically opened in the side surface portion 320. When the insertion portion 125 is vertically inserted into the slit 322, the first coupling member 120 and the side surface portion 320 may be connected to each other.

[0151] The first coupling member 120 may be connected to the side surface portion 320 in the up-down direction Z, thereby stably supporting the drain hose 100 .

[0152] In other words, the first coupling member 120 may be connected to the side surface portion 320 in the direction in which the drain hose 100 extends. At the first coupling point C1, the drain hose 100 may be arranged to extend in a substantially up-and-down direction, and at the first coupling point C1, the first coupling member 120 may be inserted and connected to the side surface portion 320 in the extending direction of the drain hose 100.

[0153] Therefore, the first coupling member 120 may be connected to the side surface portion 320 in a direction in which the drain hose 100 extends, thereby stably supporting the drain hose 100 .

[0154] However, the present disclosure is not limited thereto, and thus, the first coupling member 120 may be connected to a member of the lower frame 300 in a substantially up-down direction in addition to the side surface portion 320. Alternatively, the first coupling member 120 may be connected to an additional member forming one side of the machine room L excluding the lower frame 300 in a substantially up-down direction.

[0155] Alternatively, the first coupling member 120 may be connected to the lower frame 300 in the general front-rear direction X or left-right direction Y. However, even in this case, at the first coupling point C1, the first coupling member 120 may be connected to the lower frame 300 in the same direction as the drain hose 100 extends.

[0156] That is, when the drain hose 100 extends in the front-to-rear direction X at the first connection point C1, the first connection component 120 can be connected to the lower frame 300 in the front-to-rear direction X, and when the drain hose 100 extends in the left-to-right direction Y at the first connection point C1, the first connection component 120 can be connected to the lower frame 300 in the left-to-right direction Y.

[0157] As described above, the length of the drain hose 100 provided in the dishwasher 1 may be reduced by the first coupling member 120. In particular, the length of the first drain hose 110 connecting one end 122 of the first coupling member 120 to the sump 70 may be reduced.

[0158] When the height of the upper end of the second coupling member 113 positioned on the top of the drain hose 100 based on the water level B inside the dishwasher 1 is defined as an upper height H, the upper height H may be lower than that of the drain hose of a conventional dishwasher. This is because, as described above, the first coupling point C1 is set lower.

[0159] Therefore, the second hose fixing member 223 configured to fix the second coupling part 113 may be provided at the lower end of the air brake assembly 220. According to a conventional manner, the upper height of the drain hose of the dishwasher is formed to be higher than the approximate height at which the air brake assembly is provided, and the top of the drain hose is fixed to a position higher than the air brake assembly.

[0160] However, the upper height H according to the first embodiment of the present disclosure may be formed to correspond to the lower end of the air brake assembly 220. Therefore, the second hose fixing member 223 may correspond to a portion of the air brake assembly 220 and thus be disposed at the lower side of the air brake assembly 220.

[0161] Therefore, according to the present disclosure, the second hose fixing member 223 may be formed as one component of the air brake assembly 220 and thus may be integrally molded with the air brake assembly 220 by a method such as injection.

[0162] Therefore, there is no need to additionally fix the second hose fixing member 223 to the side surface 12 d of the tub 12 .

[0163] In addition, since the upper height H is formed to correspond to the lower end of the air brake assembly 220, the water supply hose 210 connected to the upper side of the air brake assembly 220 may not interfere with the drain hose 100 in the up and down directions on the side surface 12d of the barrel 12, thereby improving reliability.

[0164] like Figure 4 As shown, a vertical portion 100V of the drain hose 100 extending in the up-down direction therein may be arranged closer to the penetration surface 325 than a vertical portion 210V of the water supply hose 210 extending in the up-down direction therein.

[0165] The above-mentioned vertical portion 100V of the drain hose 100 may refer to a portion that is spaced apart from the second connection point C2 relative to the through-surface 325 and extends in the up-down direction. Alternatively, a vertical portion that is disposed closer to the through-surface 325 than the second connection point C2 and extends in the up-down direction to be connected to the first connection member 120 may be opposite to the vertical portion 100V. That is, the length L1 between the vertical portion 100V of the drain hose 100 and the through-surface 325 may be less than the length L2 between the vertical portion 210V of the water supply hose 210 and the through-surface 325.

[0166] As described above, since the length of the first drain hose 110 provided in the dishwasher 1 is reduced by the first coupling member 120 , the length L1 between the vertical portion 100V of the drain hose 100 and the penetration surface 325 may be reduced.

[0167] Therefore, the drain hose 100 and the water supply hose 210 may be disposed on the side surface 12 d of the tub 12 without interfering in the front-rear direction X, and thus the reliability of the dishwasher 1 may be improved.

[0168] That is, since the drain hose 100 and the water supply hose 210 are disposed on the side surface 12 d of the tub 12 without overlapping, damage and noise due to collision between the drain hose 100 and the water supply hose 210 may be prevented.

[0169] Although not shown in the drawings, an insulating member formed of a felt material may be provided between the side surface 12d of the tub 12 and the side surface of the body 10. In particular, on the side surface 12d of the tub 12, the drain hose 100 may be provided further inward than the water supply hose 210, and thus the insulating member may be effectively provided on the side surface 12d of the tub 12.

[0170] That is, the drain hose 100 and the water supply hose 210 may be arranged without crossing or interfering. In particular, the drain hose 100 may be arranged in a relatively narrow range on the side surface 12d of the tub 12, and thus the insulating member may be arranged in a relatively wide range.

[0171] Therefore, due to the effective arrangement of the drain hose 100, the insulation efficiency between the washing chamber C and the outside of the dishwasher 1 may be improved.

[0172] Features of the first coupling member 120 and technical features of the connection of the first coupling member 120 and the side surface portion 320 will be described in detail below.

[0173] Figure 7 is a perspective view of a coupling component of a dishwasher according to a first embodiment of the present disclosure, Figure 8 is a longitudinal sectional view of some components of a dishwasher according to a first embodiment of the present disclosure, Fig. 9 is a perspective view of a lower frame of a dishwasher according to a first embodiment of the present disclosure, and Fig.10 is a cross-sectional view of some components of a dishwasher according to a first embodiment of the present disclosure.

[0174] like Figures 7 to 10As shown, the first coupling member 120 may include a body 121 extending in a tubular shape, one end 122, and the other end 123. When the first coupling member 120 is connected to the side surface portion 320, the one end 122 may be disposed at an upper side, and the other end 123 may be disposed at a lower side.

[0175] The one end 122 and the other end 123 may be formed in a tubular shape extending in an up-and-down direction in the body 121 .

[0176] The inner circumferential surface of the one end 122 may be formed to allow the other end 112 of the first drain hose 110 and the vicinity of the other end 112 to be inserted therein. That is, the outer circumferential surface of the other end 112 of the first drain hose 110 and the vicinity of the first drain hose 110 may be covered by the one end 122.

[0177] As described above, the first drain hose 110 may be provided to be inserted and injection-molded into the first coupling member 120. Therefore, the one end 122 and the first drain hose 110 may be integrally formed with each other.

[0178] The other end 123 may be configured to be inserted into one end 141 of the middle portion 140. However, the present disclosure is not limited thereto, and one end 141 of the middle portion 140 may be configured to be inserted into the other end 123. At this time, the middle portion 140 may be configured to have greater strength than that of the first coupling member 120.

[0179] The first coupling member 120 may be formed to have a predetermined distance D in the extending direction of the body 121. Since the first coupling member 120 is formed to have the predetermined distance D, the supporting force of the drain hose 100 may be increased by the first coupling member 120. This will be described in detail later.

[0180] The first coupling member 120 may include an insertion portion 125 inserted into the side surface portion 320. The insertion portion 125 may be disposed outside the body 121 and extend in a direction in which the body 121 extends.

[0181] The insertion portion 125 may be disposed to be inserted into a slit 322 of the side surface portion 320 in a substantially up-and-down direction, which will be described later.

[0182] The side surface portion 320 may include a seating surface 321 provided on one side of the side surface portion 320, and the first coupling member 120 is located on the seating surface 321. The first coupling member 120 may slide through the seating surface 321 relative to the side surface portion 320, and thus the insertion portion 125 may be easily inserted into the slit 322.

[0183] The mounting surface 321 may be arranged to extend in a substantially up-down direction and to be aligned with the Fig. 9Alternatively, the seating surface 321 may extend in a direction perpendicular to the lower surface portion 310 .

[0184] The side surface part 320 may include a slit 322 cut out in the up-down direction on the seating surface 321. As described above, the slit 322 is a cut-away portion into which the insertion part 125 is vertically inserted.

[0185] The side surface portion 320 may include ribs 324 extending upward from the lower surface portion 310. The ribs 324 may be formed in a manner of continuously forming lattice ribs, thereby ensuring strength against external forces transmitted to the side surface portion 320 in the up-down direction Z or the front-rear direction X.

[0186] The penetration surface 325 may be provided on one side of the side surface portion 320. The penetration surface 325 may include a water supply through hole 325a provided to allow the water supply hose 210 to pass to the outside and a drainage through hole 325b provided to allow the second drainage hose 130 to pass to the outside.

[0187] The seating surface 321 may be provided on the edge of the rib body 324. This is to couple the first coupling member 120 to a region of the side surface portion 320 having high strength.

[0188] The side surface portion 320 may include a guide rail 323 provided on the seating surface 321 and configured to guide the first coupling member 120 to allow the insertion portion 125 to be inserted into the slit 322 .

[0189] The first coupling member 120 may include a guide portion 127. The guide portion 127 is disposed below the insertion portion 125, and when the guide portion 127 vertically moves on the seating surface 321, the guide portion 127 is inserted into the guide rail 323 and slides.

[0190] When the guide portion 127 is inserted into the guide rail 323 and vertically slides, the insertion portion 125 may be vertically inserted into the slit 322 .

[0191] The guide rail 323 may constrain the guide portion 127 in the front-rear direction X and the left-right direction Y, and thus may further improve coupling force in the front-rear direction X and the left-right direction Y when the first coupling member 120 is coupled to the side surface portion 320 .

[0192] The first coupling member 120 may include a support hook 126 disposed at an upper side of the insertion portion 125 and inserted into the slit 322 together with the insertion portion 125 and then hooked onto an inner support 327 of the slit 322 after the insertion portion 125 is inserted.

[0193] The support hook 126 may be formed to be separated by a predetermined distance from the upper portion of the insertion portion 125. The support hook 126 may be provided to have a predetermined elasticity in the front-rear direction X with respect to the upper portion of the insertion portion 125.

[0194] With respect to the front-rear direction X, the distance between the support hook 126 and the opposite end of the upper portion of the insertion portion 125 may be greater than the width of the slit 322 in the front-rear direction X. Therefore, when the insertion portion 125 is inserted into the slit 322, the support hook 126 may be pressed against the slit 322 in the front-rear direction X, and the distance between the support hook 126 and the opposite end of the upper portion of the insertion portion 125 in the front-rear direction X may become less than or equal to the width of the slit 322 in the front-rear direction X. Therefore, the insertion portion 125 and the support hook 126 may pass through the slit 322.

[0195] When the insertion portion 125 passes through the gap 322 and is fully inserted into the side surface portion 320, the support hook 126 can also pass through the gap 322, and through elastic force, the distance between the support hook 126 and the opposite end of the upper part of the insertion portion 125 in the front-to-back direction X can return to a previous state that is longer than the width of the gap 322 in the front-to-back direction X.

[0196] Therefore, the support hook 126 may be hooked onto the inner support piece 327. The inner support piece 327 is formed on opposite sides of the seating surface 321 and is positioned on the outer side of the slit 322 with respect to the front-rear direction X.

[0197] In particular, the support hook 126 may include a support groove 126a formed in an upper side of the support hook 126 and formed in a groove shape. When the inner support 327 is hooked to the support hook 126, the support groove 126a may contact the inner support 327. Therefore, the support hook 126 may be constrained to the inner support 327 in the up-down direction Z, thereby preventing the first coupling member 120 from being detached from the side surface portion 320.

[0198] In addition, since the support hook 126 is hooked to the inner support member 327 when the insertion portion 125 is inserted into the side surface portion 320, the insertion portion 125 can be prevented from moving in the front-rear direction X or the left-right direction Y, thereby preventing the first connecting member 120 from being detached from the side surface portion 320.

[0199] Furthermore, as described above, the guide portion 127 may be restricted to the guide rail 323 in the front-rear direction X or the left-right direction Y, thereby additionally preventing the first coupling member 120 from being disengaged from the side surface portion 320 .

[0200] The first coupling member 120 may include a rib 124 configured to connect the insertion portion 125 and the guide portion 127 to the body 121. The rib 124 may be provided with a plurality of ribs arranged in a zigzag shape, so that even when an external force transmitted to the body 121 is transmitted to the insertion portion 125 or the guide portion 127, the rib 124 may maintain its strength.

[0201] The rib 124 may be provided to allow the body 121 to be inclined at a predetermined angle θ with respect to the up-down direction Z based on coupling between the first coupling member 120 and the side surface portion 320 .

[0202] Since the body 121 is inclined at the predetermined angle θ with respect to the up-down direction Z, a space in which the first drain hose 110 and the second drain hose 130 are bent may be additionally ensured.

[0203] Suitably, the predetermined angle θ is formed from 0 degrees to 45 degrees.

[0204] Therefore, the curvature of the curved surfaces of the first drain hose 110 and the second drain hose 130 may be increased, so that the resistance of the wash water flowing in the first drain hose 110 and the second drain hose 130 may be reduced.

[0205] The first coupling member 120 may be easily separated from the side surface portion 320 as needed.

[0206] like Figure 8 As shown, the insertion portion 125 and the support hook 126 passing through the slit 322 may be disposed in a space 326 formed between the lattice ribs of the rib body 324 .

[0207] When the user wants to detach the first coupling member 120 connected to the side surface portion 320, the user may insert a finger or the like into the space 326 formed between the lattice ribs of the rib body 324 and press the support hook 126 in the front-rear direction X. When the support hook 126 is pressed in the front-rear direction X, the distance between the support hook 126 and the opposite end of the upper portion of the insertion portion 125 in the front-rear direction X may become smaller than or equal to the width of the slit 322 in the front-rear direction X. Therefore, the constraint of the first coupling member 120 in the up-down direction Z may be released.

[0208] When the user presses the first coupling member 120 upward, the constraint of the first coupling member 120 in the up-down direction Z may be released, and thus the user may easily separate the first coupling member 120 in the up-down direction.

[0209] As described above, since the side surface portion 320 and the first coupling member 120 are easily connected to or separated from each other while sliding in the up-and-down directions, the assembly of the drain hose 100 may be improved.

[0210] Furthermore, since the first coupling member 120 is connected to the side surface portion 320 in the up-down direction as described above, even when external force is transmitted to the first coupling member 120 in the front-rear direction X or the left-right direction Y, the first coupling member 120 can maintain high strength without being separated.

[0211] Most of the external force transmitted to the first coupling member 120 may be transmitted through the second drain hose 130. When the user moves the dishwasher 1 or installs the dishwasher 1, especially when the user connects the second drain hose 130 to the outside, tension may be generated in the second drain hose 130, and thus bending stress may be transmitted to the first coupling member 120.

[0212] As described above, when the one end 141 of the middle portion 140 is disposed in the up-down direction Z, the other end 142 of the middle portion 140 may be disposed in the front-rear direction X or the left-right direction Y. Therefore, the bending stress generated by the second drain hose 130 may be formed in the front-rear direction X or the left-right direction Y, and the bending stress may not be transmitted in the up-down direction Z. Therefore, the first coupling member 120 may maintain the coupling force without being separated by an external force.

[0213] As described above, the first coupling member 120 may extend to have the predetermined distance D, and thus the first coupling member 120 may ensure strength against bending stress generated by the second drain hose 130 .

[0214] The other end 123 may be disposed at any position in the up-down direction Z according to a predetermined distance D of the first coupling member 120 .

[0215] When the other end 123 is disposed at any position with respect to the up-down direction Z, the middle portion 140 or the second drain hose 130 connected to the other end 123 may be pulled upward from the lower surface portion 310 to be positioned at a height at which the other end 123 is disposed.

[0216] That is, the bending stress transferred to the first coupling member 120 may be changed according to the height at which the other end 123 is provided, and thus, by adjusting the predetermined distance D of the first coupling member 120 , the bending stress transferred to the first coupling member 120 may be easily set.

[0217] On the other hand, the one end 122 may be disposed at any position in the up-down direction Z according to the value of the predetermined distance D of the first coupling member 120 .

[0218] The curvature of the arc section R can be changed based on the position where the one end 122 is set relative to the up-down direction Z, and thus the curvature of the arc section R can be easily set by adjusting the predetermined distance D of the first coupling member 120. The first coupling member 170 of the dishwasher 1 according to the second embodiment of the present disclosure will be described below. Except for the components of the first coupling member 170 described below, the components of the dishwasher 1 are the same as those of the dishwasher 1 according to the first embodiment of the present disclosure, and thus a description thereof will be omitted.

[0230] The drain hose 100' may include a first coupling part 180. The hose body 110' may be inserted and injection-molded into the first coupling part 180. Therefore, the hose body 110' and the first coupling part 180 may be integrally formed with each other.

[0231] However, the present disclosure is not limited thereto, and the hose body 110' and the first coupling member 180 may be injection molded as one molded part. Therefore, the hose body 110' and the first coupling member 180 may be formed as a single injection molding material. Therefore, the drain hose 100' may be formed as a single injection molding material.

[0232] Inner circumferential surfaces of the body 181 , the one end 182 , and the other end 183 of the first coupling member 180 may be provided to allow the hose body 110 ′ to be inserted thereinto.

[0233] The insertion portion 185 of the first coupling member 180 may extend in a direction corresponding to a direction in which the hose body 110 ′ extends within the first coupling member 180 .

[0234] Therefore, the washing water of the dishwasher 1 may be discharged using the single hose body 110 ′, thereby improving assembly performance and reducing manufacturing costs.

[0235] The drain hose 100' of the dishwasher 1 according to the fourth embodiment of the present disclosure will be described below. Components of the dishwasher 1 except for the components of the drain hose 100' described below are the same as those of the dishwasher 1 according to the third embodiment of the present disclosure, and thus description thereof will be omitted.

[0239] The first coupling member 190 may include a body 191 configured to cover at least a portion of the outer circumferential surface of the hose body 110 ′ of the first coupling member 190 .

[0240] The body 191 may be formed in a tubular shape extending in one direction, and may include a cut-off portion 192 in which a portion of the tube is cut outward.

[0241] As described above, the first coupling member 190 may be separated from the hose body 110 ′, and the hose body 110 ′ may be inserted into the interior 193 of the body 191 through the cut-away portion 192 .

[0242] A distance D in a direction of the cut-off portion 192 perpendicular to the longitudinal direction of the body 191 may be smaller than a diameter of the hose body 110 ′.

[0243] The hose body 110' and the body 191 may be formed of a material having a predetermined elasticity. It is suitable that the hose body 110' and the body 191 are formed of a plastic injection molding material.

[0244] Since the hose body 110 ′ and the body 191 have predetermined elasticity, the hose body 110 ′ may be fitted into the inside of the body 191 even though the diameter of the drain hose 110 ′ is greater than the width d of the cut-off portion 192 .

[0245] However, the present disclosure is not limited thereto, and a distance d in a direction perpendicular to the longitudinal direction of the body 191 of the cutout portion 192 may be set to correspond to the diameter of the hose body 110'. At this time, the first coupling member 190 may include a restraining portion configured to further restrain the hose body 110'.

[0246] The restraining portion may be used as an additional member configured to couple the hose body 110 ′ to the first coupling member 190 , or as an additional portion formed in the body 191 .

[0247] After the first coupling member 190 is connected to the hose body 110', the insertion portion 195 may be inserted into the side surface portion 320. Alternatively, after the insertion portion 195 is inserted into the side surface portion 320, the first coupling member 190 may be connected to the hose body 110.

[0248] Therefore, the assembly order of the drain hose 100 ′ may be improved by changing the coupling order according to circumstances.

[0249] The side surface portion 320' and the drain hose 100' of the dishwasher 1 according to the fifth embodiment of the present disclosure will be described below. Except for the components of the side surface portion 320' and the drain hose 100' described below, the components of the dishwasher 1 are the same as those of the dishwasher 1 according to the first embodiment of the present disclosure, and thus the description thereof will be omitted.

[0250] Fig.16 is a perspective view of a lower frame of a dishwasher according to a fifth embodiment of the present disclosure, Fig.17 is a perspective view of a portion of a dishwasher according to a fifth embodiment of the present disclosure.

[0254] The second portion 110 a ′ may extend to have a predetermined distance d1 , and the side surface portion 320 ′ may be connected to the drain hose 100 ′ through the predetermined distance d1 .

[0255] The second portion 110a' may be formed to be longer than the first portion (not shown) in the extending direction of the hose body 110'.

[0256] Therefore, in the drain hose 100 ′, a portion connected to the side surface portion 320 ′ may be longer than a portion connected to the tub 12 .

[0257] In addition, like the above-described embodiment, the drain hose 100 ′ and the tub 12 may be connected to each other in the front-rear direction X, and the drain hose 100 ′ and the side surface portion 320 ′ may be connected to each other in the up-down direction Z.

[0258] Unlike the above-described embodiment, the drain hose 100' according to the fifth embodiment may not include a coupling member. That is, the drain hose 100' may be formed of a single hose body 110'.

[0259] The side surface portion 320' may include a coupling area 322' connected to the drain hose 100'. The hose body 110' may be detachably connected to the coupling area 322'.

[0260] The coupling region 322' corresponding to one region of the side surface portion 320' may be integrally formed with the side surface portion 320'. That is, the coupling region 322' may be formed by being integrally injected with the side surface portion 320'.

[0261] The side surface portion 320 ′ may include a sidewall 321 ′ extending in the up-down direction Z. The coupling region 322 ′ may be provided at an outer side of the sidewall 321 ′.

[0262] The rib region 323' may be disposed between the coupling region 322' and the sidewall 321'. The rib region 323' may connect the sidewall 321' to the coupling region 322'.

[0263] By using the rib region 323 ′, the side surface portion 320 ′ may ensure strength against an external force transferred from the coupling region 322 ′.

[0264] The sidewall 321', the coupling region 322', and the rib region ' may be integrally formed with the side surface portion 320'. That is, the sidewall 321', the coupling region 322', and the rib region ' may be integrally injected with the side surface portion 320'.

[0265] The coupling region 322 ′ may include a body region 322 a ′ configured to cover an outer circumferential surface of at least a portion of the second portion 110 a ′.

[0266] The body region 322a' may be formed in a tubular shape extending in one direction, and may include a cut-away portion 322b' in which a portion of the tube is cut outward.

[0267] As described above, the coupling region 322' may be separated from the hose body 110', and the hose body 110' may be inserted into the inside of the body region 322a' through the cut-away portion 322b'.

[0268] That is, the coupling area 322 ′ may be a member corresponding to that of the first coupling member 190 disclosed in the fourth embodiment, and the coupling area 322 ′ may be formed on the side surface portion 320 ′ instead of being formed in the drain hose 100 ′.

[0269] Therefore, since the drain hose 100 ′ formed as a single component is assembled in the dishwasher 1 and the coupling region 322 ′ to which the drain hose 100 ′ is connected is integrally formed with the side surface portion 320 ′, the assembly of the drain hose 100 ′ may be improved.

[0270] Although several embodiments of the present disclosure have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the present disclosure, the scope of which is defined in the claims and their equivalents.
