For example, unlike the second spraying unit 42 and the third spraying unit 43, the first spraying unit 41 can be fixed to the lower surface 12b of the inner tank 12. In this case, the first spraying unit 41 is configured to spray washing water in a substantially horizontal direction through a fixed nozzle, and the washing water sprayed from the nozzle of the first spraying unit 41 in a substantially horizontal direction can move upward as its direction is changed by a switching assembly (not shown) disposed inside the washing chamber 10a. The switching assembly is mounted on a track (not shown) and can be configured to be able to translate along the track. Although the first spraying unit 41 has been described above as an example, the second spraying unit 42 and the third spraying unit 43 can also be configured to spray washing water using fixed nozzles, as in the example described above.

[0082] The dishwasher 1 may include an auxiliary spray device 30. The auxiliary spray device 30 may be disposed on one side of the lower portion of the washing chamber 10a to spray washing water into a region of the washing chamber 10a. The auxiliary spray device 30 is designed to spray water at a relatively higher pressure compared to the spray device 40, thereby enabling intensive washing of heavily soiled dishes. The auxiliary spray device 30 may be referred to as an auxiliary spray unit 30. The auxiliary spray device 30 may be configured to spray washing water while rotating. The auxiliary spray device 30 may be referred to as an auxiliary spray rotor 30.

[0083] The auxiliary injection device 30 may be configured as a component of the injection device 40.

[0089] For example, at least a portion of the storage tank 70 can be located in the machine room 10b. A large portion of the storage tank 70 can also be located in the machine room 10b. That is, the area of ​​the storage tank 70 located in the washing chamber 10a can be smaller than the area of ​​the storage tank 70 located in the machine room 10b. By reducing the area occupied by the storage tank 70 in the washing chamber 10a, the area of ​​the washing chamber 10a can be ensured. Therefore, the capacity of the washing chamber 10a can be increased, thereby increasing the capacity for storing tableware.

[0090] The dishwasher 1 may include a filter assembly 60. The filter assembly 60 may be configured to filter out foreign matter contained in the wash water introduced into the reservoir 70. The wash water filtered by the filter assembly 60 may be pumped by a circulation pump 71 to be supplied to the piping assembly 80 and / or the jet device 40.

The second pipe 200 may be configured to guide the washing water supplied from the first pipe 100. The second pipe 200 may direct the washing water supplied from the first pipe 100 to at least one spray unit 41, 42 and / or 43. For example, the second pipe 200 may be configured to deliver washing water to a second spray unit 42. For example, the second pipe 200 may be detachably connected to the first pipe 100. For example, the second pipe 200 may be positioned upstream of the first pipe 100. For example, the second spray unit 42 may be detachably connected to the second pipe 200, or the second spray unit 42 may be integrally disposed with the second pipe 200.

[0096] The dishwasher 1 may include a third pipe 300 connected to the first pipe 100. The third pipe 300 may receive washing water from the first pipe 100. The third pipe 300 may be configured to guide the washing water supplied from the first pipe 100. The third pipe 300 may guide the washing water supplied from the first pipe 100 to at least one spray unit 41, 42 and / or 43. For example, the third pipe 300 may be configured to deliver washing water to a third spray unit 43. For example, the third pipe 300 may be detachably connected to the first pipe 100. For example, the third pipe 300 may be positioned above the first pipe 100. For example, the third spray unit 43 may be detachably connected to the third pipe 300, or the third spray unit 43 may be integrally disposed with the third pipe 300.

[0097] The first pipe 100, the second pipe 200, and the third pipe 300 are not restricted by the ordinal numbers "first", "second", and "third". For example, the first pipe 100 can be referred to as the second pipe 100, and the second pipe 200 can be referred to as the first pipe 200.

[0098] The attached diagram shows that dishwasher 1 includes three pipes 100, 200 and 300, but there is no limit to the number of pipes.

[0099] The accompanying drawings illustrate that the first spray unit 41 receives washing water directly from the storage tank 70, and the second spray unit 42 and the third spray unit 43 receive washing water from the storage tank 70 through the second pipe 200 and the third pipe 300, respectively; however, this disclosure is not limited thereto. For example, the first spray unit 41 may receive washing water from the storage tank 70 through at least one of the pipes.

The second pipe 200 can be configured to mate with the first pipe 100 as the basket 52 is inserted into the inner liner 12. The second pipe 100 can be connected to the first pipe 100 by moving in a first direction A. For example, the first direction A can be a rearward direction (-X direction). When the first pipe 100 and the second pipe 200 are mated, washing water inside the first pipe 100 can flow into the second pipe 200.

[0105] The second pipe 200, fixed to the basket 52, can be pulled out from the inner liner 12. As the basket 52 is pulled out of the inner liner 12, the second pipe 200 can separate from the first pipe 100. As the basket 52 is pulled out of the inner liner 12, the second pipe 200 can be positioned to detach from the first pipe 100. The second pipe 200 can separate from the first pipe 100 by moving in a second direction B, opposite to the first direction A. For example, the second direction B can be a forward direction (+X direction).

Figure 12 Is Figure 10 An enlarged view of section E shown.

[0109] The first conduit 100 may include a first frame 110. The first frame 110 may form a flow path through which the washing water flows. The first frame 110 may be configured to guide the washing water supplied from the storage tank 70. For example, the first frame 110 may include a first body portion 111 and a second body portion 112. The first body portion 111 and the second body portion 112 may be configured to substantially intersect.

[0110] The first conduit 100 may include a first flange 120. The first flange 120 may be configured to allow washing water guided by the first frame 110 to flow out. For example, the first flange 120 may be configured to allow washing water to flow out in a second direction B. The first flange 120 may include an outlet orifice 120h. The washing water flowing out of the first flange 120 may be introduced into the second conduit 200. For example, the first flange 120 may include a hollow shape. For example, the first flange 120 may project forward from the first frame 110. For example, the first flange 120 may project from the first frame 110 in a second direction B. For example, the first flange 120 may be formed on the second body portion 112. For example, the first flange 120 may be referred to as a first outlet 120.

[0111] The first flange 120 may include a first wall portion 121. The first wall portion 121 may be formed on the outer surface 120a of the first flange 120. For example, the first wall portion 121 may extend along the circumferential direction of the first flange 120. The first wall portion 121 may be formed adjacent to the first side 1231 of the groove 123, which will be described later.

[0112] The first flange 120 may include a second wall portion 122. The second wall portion 122 may be spaced apart from the first wall portion 121 along a second direction B opposite to the first direction A. The second wall portion 122 may be disposed in front of the first wall portion 121. The second wall portion 122 may be formed on the outer surface 120a of the first flange 120. For example, the second wall portion 122 may extend along the circumferential direction of the first flange 120. The second wall portion 121 may be formed adjacent to the second side 1232 of the groove 123, which will be described later.

[0113] The first flange 120 may include a groove 123. The groove 123 may be formed between a first wall portion 121 and a second wall portion 122.

The groove 123 may be configured to be recessed relative to the first wall portion 121 and the second wall portion 122. For example, the groove 123 may be formed on the outer surface 120a of the first flange 120. For example, the groove 123 may extend along the circumferential direction of the first flange 120.

[0114] The first flange 120 may include a shape that widens along the second direction B. The groove 123 may be configured to widen along the second direction B (see [reference]). Figure 10 and Figure 11The groove 123 can be configured to taper along a first direction A. The groove 123 can be widened along a second direction B to have a ramp. For example, the first flange 120 can have an increased outer diameter by projecting forward from the first frame 110. For example, the groove 123 can be configured to have a truncated conical shape. For example, the inclination angle α of the groove 123 can be 1 degree or greater. For example, the inclination angle α of the groove 123 can be about 4 degrees. However, this disclosure is not limited to the above examples and can vary depending on various design conditions / factors, etc. For example, the inclination angle α of the groove 123 can vary depending on the length of the groove 123 along the first direction A (or the second direction B), the distance between the first sealing protrusion 410 and the second sealing protrusion 420 of the sealing member 400, and / or the amount of compression of the sealing member 400.

[0115] The groove 123 may include a first side 1231 adjacent to the first wall portion 121 and a second side 1232 adjacent to the second wall portion 122. The second side 1232 may be spaced apart from the first side 1231 along a second direction B. For example, the first side 1231 of the groove 123 may be configured to correspond to a first sealing protrusion 410 of the sealing member 400 when the sealing member 400 is mounted on the first flange 120, as will be described later. For example, the second side 1232 of the groove 123 may be configured to correspond to a second sealing protrusion 420 of the sealing member 400 when the sealing member 400 is mounted on the first flange 120, as will be described later. For example, the groove 123 may have a shape that slopes from the first side 1231 to the second side 1232. For example, the outer diameter of the groove 123 may be configured to increase along the second direction B. For example, the outer diameter D1 of the first side 1231 of the groove 123 may be smaller than the outer diameter D2 of the second side 1232 of the groove 123. For example, the outer diameter of the groove 123 can be set to increase from the first side 1231 toward the second side 1232.

[0116] The first flange 120 may include a mounting recess 124. The mounting recess 124 may be defined by a first wall portion 121, a second wall portion 122, and a recess 123. A sealing member 400 may be disposed in the mounting recess 124. The sealing member 400 may be fitted into the mounting recess 124.

[0117] The first flange 120 may include a first chamfer 125. The first chamfer 125 may be configured to taper or narrow from the second wall portion 122 along a second direction B. The first chamfer 125 may be located at the front end of the first flange 120. The second flange 220 of the second pipe 200, which will be described later, may be smoothly connected to the first flange 120 via the first chamfer 125.

[0118] The first conduit 100 may include a first inlet 130. Washing water can be introduced into the first frame 110 through the first inlet 130. The first inlet 130 may be connected to a storage tank 70. The first inlet 130 may communicate with the storage tank 70. For example, the first inlet 130 may be formed on the first body portion 111.

[0119] The second conduit 200 may include a second frame 210. The second frame 210 may form a flow path through which the washing water flows. The second frame 210 may be configured to guide the washing water supplied from the first conduit 100. The second frame 210 may be configured to guide washing water introduced through the second flange 220 to the spray unit 42. For example, the second frame 210 may extend forward from the second flange 220. For example, the second frame 210 may extend from the second flange 220 along a second direction B.

[0120] The second conduit 200 may include a second flange 220. The second flange 220 may be configured to allow the introduction of washing water flowing from the first flange 120. The second flange 220 may be configured to receive washing water flowing from the first flange 120. The second flange 220 may include an inlet port 220h. For example, the second flange 220 may include a hollow shape. For example, the first flange 220 may be referred to as the second inlet 220.

[0121] The second flange 220 can be configured to connect to the first flange 120. The second flange 220 can be configured to mate with the first flange 120. The second flange 220 can be connected to the first flange 120 along a first direction A. The second flange 220 can mate with the first flange 120 along a first direction A.

[0122] The second flange 220 can be configured to surround the first flange 120 when the second flange 220 is connected to the first flange 120. The second flange 220 can be configured to cover the first flange 120 when the second flange 220 is mated with the first flange 120. The first flange 120 can be configured to be positioned inside the second flange 220 when the second flange 220 is mated with the first flange 120. For example, the inner surface 220a of the second flange 220 can be configured to face the outer surface 120a of the first flange 120. For example, the inner surface 220a of the second flange 220 can be configured to surround the outer surface 120a of the first flange 120. For example, the inlet hole 220h of the second flange 220 can be larger than the outlet hole 120h of the first flange 120.

[0123] For example, the second flange 220 can be configured to mate with the first flange 120 as the basket 52, which is fixed to the second pipe 200, is inserted into the inner liner 12 (see [reference]). Figure 3 and Figure 4 For example, the second flange 220 can be configured to disengage from the first flange 120 as the basket 52 attached to the second pipe 200 is pulled out of the inner liner 12 (see [reference]). Figure 3 and Figure 4 For example, as the second flange 220 is mated to the first flange 120, at least a portion of the first flange 120 can be inserted into the second flange 220.

[0124] The second flange 220 may include a second chamfer 225. The second chamfer 225 may be configured to correspond to the first chamfer 125 when the second flange 220 is connected to the first flange 120. The second chamfer 225 may be located at the rear end of the second flange 220. The second flange 220 can be smoothly connected to the first flange 120 via the second chamfer 225.

[0125] The second conduit 200 may include a second outlet 230. The second outlet 230 may be configured to allow washing water guided by the second frame 210 to flow out. The second outlet 230 may be connected to the spray unit 42. The second outlet 230 may communicate with the spray unit 42. For example, the second outlet 230 may be formed on the underside of the second frame 210.

[0126] The second conduit 200 may include a check valve 240. The check valve 240 prevents backflow of washing water. The check valve 240 prevents washing water flowing from the first conduit 100 toward the second conduit 200 from flowing back into the first conduit 100. For example, the check valve 240 may allow washing water to flow in a second direction B. For example, the check valve 240 may restrict the flow of washing water in a first direction A. For example, the check valve 240 may be secured to the second frame 210 via a second flange 220. For example, the check valve 240 may be detachably connected to the second frame 210 and / or the second flange 220. For example, the check valve 240 may be integrally formed with the second frame 210 and / or the second flange 220.

[0127] The second conduit 200 may include a basket fixing portion 250 configured to secure the basket 52. The basket fixing portion 250 may be formed on the frame 210. The basket fixing portion 250 may include at least one fixing rib 251, 252, 253 and / or 254. For example, the at least one fixing rib 251, 252, 253 and / or 254 may include a hook. For example, the at least one fixing rib 251, 252, 253 and / or 254 may be configured to secure the wire constituting the basket 52.

[0128] A sealing member 400 can be configured to seal between a first pipe 100 and a second pipe 200. The sealing member 400 can be mounted on a first flange 120 of the first pipe 100. With a second flange 220 connected to the first flange 120 while the sealing member 400 is mounted on the first flange 120, the sealing member 400 can seal between the first flange 120 and the second flange 220. The sealing member 400 can prevent leakage of washing water between the first flange 120 and the second flange 220. The sealing member 400 may include an annular shape.

[0129] The sealing member 400 may include a sealing body 430. The sealing body 430 may be mounted on the outer surface of the first flange 120. The sealing body 430 may be mounted in a recess 123 of the first flange 120. The sealing body 430 may be disposed in the recess 123. The sealing body 430 may be fitted into the recess 123.

[0130] The sealing member 400 may include a first sealing protrusion 410. The first sealing protrusion 410 may protrude from the sealing body 430. The first sealing protrusion 410 may protrude from the sealing body 430 along a third direction C, which is the radial direction of the sealing member 400. The first sealing protrusion 410 may have a shape that extends along the circumferential direction of the sealing member 400. For example, the first sealing protrusion 410 may be formed on one side of the sealing member 400.

[0131] The sealing member 400 may include a second sealing protrusion 420. The second sealing protrusion 420 may be spaced apart from the first sealing protrusion 410. The second sealing protrusion 420 may protrude from the sealing body 430 along a third direction C, which is the radial direction of the sealing member 400. For example, the second sealing protrusion 420 may have a shape extending along the circumferential direction of the sealing member 400. For example, the second sealing protrusion 420 may be formed on another side of the sealing member 400. For example, the second sealing protrusion 420 may be formed on a side of the sealing member 400 opposite to the side where the first sealing protrusion 410 is formed.

[0132] For example, the first sealing protrusion 410 and the second sealing protrusion 420 can be configured symmetrically with respect to the vertical centerline V of the sealing member 400. The first sealing protrusion 410 and the second sealing protrusion 420 can have the same shape. Therefore, it is possible to prevent the sealing member 400 from being incorrectly assembled to the first flange 120. For example, the user does not need to distinguish between the front and rear sides of the first sealing protrusion 410 and the second sealing protrusion 420. For example, the sealing member 400 can be mounted on the first flange 120 such that the first sealing protrusion 410 is positioned behind the second sealing protrusion 420 (hereinafter referred to as the first mounting state of the sealing member 400), and the sealing member 400 can be mounted on the first flange 120 such that the second sealing protrusion 420 is positioned behind the first sealing protrusion 410 (hereinafter referred to as the second mounting state of the sealing member 400). That is, both the first mounting state and the second mounting state of the sealing member 400 can be in a correctly assembled state. However, this disclosure is not limited to the above examples, and the first sealing protrusion 410 and the second sealing protrusion 420 of the sealing member 400 may include various shapes for sealing between the first conduit 100 and the second conduit 200.

[0133] The sealing member 400 may include a reinforcing portion 440. The reinforcing portion 440 may be formed between the first sealing protrusion 410 and the second sealing protrusion 420. The reinforcing portion 440 may protrude from the sealing body 430 between the first sealing protrusion 410 and the second sealing protrusion 420. For example, the reinforcing portion 440 may protrude from the sealing body 430 along a third direction C between the first sealing protrusion 410 and the second sealing protrusion 420. For example, the reinforcing portion 440 may have a shape extending in the circumferential direction of the sealing member 400. For example, the thickness of the reinforcing portion 440 along the third direction C may be thinner than the thickness of the first sealing protrusion 410 along the radial direction C. For example, the thickness of the reinforcing portion 440 along the third direction C may be thinner than the thickness of the second sealing protrusion 420 along the radial direction C. For example, the length of the first sealing protrusion 410 protruding from the sealing body 430 may be longer than the length of the reinforcing portion 440 protruding from the sealing body 430. For example, the length by which the second sealing protrusion 420 protrudes from the sealing body 430 may be longer than the length by which the reinforcing portion 440 protrudes from the sealing body 430. For example, the first sealing protrusion 410 and the second sealing protrusion 420 may be configured to protrude further from the sealing body 430 than the reinforcing portion 440.

[0134] The reinforcing portion 440 can be configured to enhance the strength of the sealing member 400. The sealing member 400 will not deviate from the groove 123 due to forces (e.g., friction) generated when the second flange 220 is connected to or separated from the first flange 120. Therefore, the sealing member 400 will not deform due to forces (e.g., friction) generated when the second flange 220 is connected to or separated from the first flange 120. When the second flange 220 is connected to or separated from the first flange 120, the sealing member 400 will not be crushed or damaged by other components.

[0135] The first sealing protrusion 410 may be configured to protrude further from the sealing body 430 than the reinforcing portion 440. The second sealing protrusion 420 may be configured to protrude further from the sealing body 430 than the reinforcing portion 440.

[0136] The sealing member 400 may include a first notch 450. The first notch 450 may be configured adjacent to a first sealing protrusion 410. The first notch 450 may be formed between the first sealing protrusion 410 and the reinforcing portion 440. The first notch 450 may be configured to be recessed between the first sealing protrusion 410 and the reinforcing portion 440. For example, because the first sealing protrusion 410 and the reinforcing portion 440 protrude from the sealing body 430, the first notch 450 may be interpreted as a relatively recessed portion of the sealing body 430. Alternatively, for example, because the first notch 450 is recessed from the sealing body 430, the first sealing protrusion 410 and the reinforcing portion 440 may be interpreted as relatively protruding portions of the sealing body 430. For example, the first notch 450 may include a curved shape. The first notch 450 may be referred to as a first recessed portion 450.

[0137] With the aid of the first notch 450, the first sealing protrusion 410 can be configured to be more flexible. The first sealing protrusion 410 can be configured to bend toward the first notch 450. Therefore, the second flange 220 can be more smoothly connected to or more smoothly separated from the first flange 120.

[0138] The sealing member 400 may include a second recess 460. The second recess 460 may be configured adjacent to the second sealing protrusion 420. The second recess 460 may be formed between the second sealing protrusion 420 and the reinforcing portion 440. The second recess 460 may be configured to be recessed between the second sealing protrusion 420 and the reinforcing portion 440. For example, because the second sealing protrusion 420 and the reinforcing portion 440 protrude from the sealing body 430, the second recess 460 may be interpreted as a relatively recessed portion of the sealing body 430. Alternatively, for example, because the second recess 460 is recessed from the sealing body 430, the second sealing protrusion 420 and the reinforcing portion 440 may be interpreted as relatively protruding portions of the sealing body 430. For example, the second recess 460 may include a curved shape. The second recess 460 may be referred to as the second recessed portion 460.

[0139] With the aid of the second notch 460, the second sealing protrusion 420 can be configured to be more flexible. The second sealing protrusion 420 can be configured to bend toward the second notch 460. Therefore, the second flange 220 can be more smoothly connected to or more smoothly separated from the first flange 120.

[0140] The length L1 of the sealing member 400 along the second direction B can be longer than the thickness L2 of the sealing member 400 along the third direction C. The length L1 of the sealing member 400 along the first direction A can be longer than the thickness L2 of the sealing member 400 along the third direction C. Therefore, when the sealing member 400 is installed in the groove 123, the sealing member 400 will not easily deviate from the groove 123.

[0142] When the first sealing protrusion 410 and the second sealing protrusion 420 are symmetrical with respect to the vertical center line V of the sealing member 400, the first sealing protrusion 410 and the second sealing protrusion 420 can be substantially identical and can be indistinguishable from each other when the sealing member 400 is not mounted on the first flange 120. However, when the sealing member 400 is mounted on the first flange 120, the first sealing protrusion 410 and the second sealing protrusion 420 can be distinguished by the inclination of the first flange 120. In the following description, the case where the first sealing protrusion 410 is positioned behind the second sealing protrusion 420 will be used as an example. When the second sealing protrusion 420 is positioned behind the first sealing protrusion 410, the following description relating to the first sealing protrusion can be applied to the sealing protrusion 420, and the following description relating to the second sealing protrusion can be applied to the sealing protrusion 410. That is, the following description of the first sealing protrusion can correspond to the description of the rearward-positioned sealing protrusion of the two sealing protrusions 410 and 420. The following description of the second sealing protrusion corresponds to the description of the front-positioned sealing protrusion in the two sealing protrusions 410 and 420.

[0143] refer to Figures 13 to 15 The second flange 220 of the second pipe 200 can be connected to the first flange 120 of the first pipe 100 on which the sealing member 400 is mounted. The sealing member 400 can seal between the first flange 120 and the second flange 220. The sealing member 400 can prevent washing water from leaking between the first flange 120 and the second flange 220. For example, the sealing member 400 can seal between the outer surface 120a of the first flange 120 and the inner surface 220a of the second flange 220.

[0144] The first sealing protrusion 410 may be spaced apart from the second sealing protrusion 420 along a first direction A. The second sealing protrusion 420 may be spaced apart from the first sealing protrusion 410 along a second direction B. The second sealing protrusion 420 may be positioned in front of the first sealing protrusion 410. The first sealing protrusion 410 may be positioned behind the second sealing protrusion 420. The second sealing protrusion 420 may be configured to face the inner surface 220a of the second flange 220 in front of the first sealing protrusion 410 when the second flange 220 is mated with the first flange 120. For example, the first sealing protrusion 410 may protrude from the rear end of the sealing body 430, and the second sealing protrusion 420 may protrude from the front end of the sealing body 430.

[0145] The first sealing protrusion 410 may include a first inclined portion 411 configured to taper or narrow along a first direction A. The second sealing protrusion 420 may include a second inclined portion 421 configured to taper or narrow along a second direction B. Therefore, interference between the sealing member 400 and the second flange 220 can be minimized when the second flange 220 is engaged with or disengaged from the first flange 120. The second flange 220 can smoothly mate with the first flange 120. The second flange 220 can smoothly disengage from the first flange 120.

[0146] When the sealing member 400 is mounted on the first flange 120, the first sealing protrusion 410 may be positioned adjacent to the first wall portion 121. When the sealing body 430 is mounted in the recess 123, the first sealing protrusion 410 may be positioned adjacent to the first wall portion 121. When the sealing body 430 is mounted in the recess 123, the first sealing protrusion 410 may be adjacent to the first side 1231 of the recess 123. When the sealing body 430 is mounted in the recess 123, the first sealing protrusion 410 may be positioned corresponding to the first side 1231 of the recess 123.

[0147] When the sealing member 400 is mounted on the first flange 120, the second sealing protrusion 420 may be positioned adjacent to the second wall portion 122. When the sealing body 430 is mounted in the recess 123, the second sealing protrusion 420 may be positioned adjacent to the second wall portion 122. When the sealing body 430 is mounted in the recess 123, the second sealing protrusion 420 may be adjacent to the second side 1232 of the recess 123. When the sealing body 430 is mounted in the recess 123, the second sealing protrusion 420 may be positioned corresponding to the second side 1232 of the recess 123.

[0148] As described above, the first flange 120 of the first pipe 100 may have a shape that widens along the second direction B. The groove 123 of the first flange 120 may have a ramp. The first flange 120 of the first pipe 100 may have a substantially truncated conical shape. Therefore, with the sealing member 400 installed on the first flange 120, the second sealing protrusion 420 may be configured to protrude further than the first sealing protrusion 410. For example, when the sealing body 430 is installed in the groove 123 of the first flange 120, the second sealing protrusion 420 may be configured to protrude further than the first sealing protrusion 410 relative to the horizontal centerline H or axial centerline of the sealing member 400. For example, when the sealing body 430 is installed in the groove 123 of the first flange 120, the second sealing protrusion 420 may protrude further than the first sealing protrusion 410 in the third direction C.

[0149] When the sealing member 400 is mounted on the first flange 120 and the second flange 220 is connected to the first flange 120, the second sealing protrusion 420 can be configured to contact the second flange 220. When the sealing body 430 is mounted in the recess 123 and the second flange 220 is connected to the first flange 120, the second sealing protrusion 420 can be configured to contact the second flange 220. When the sealing body 430 is mounted in the recess 123 and the second flange 220 is connected to the first flange 120, the second sealing protrusion 420 can be configured to contact the inner surface 220a of the second flange 220. The second sealing protrusion 420 may interfere with the inner surface 220a of the second flange 220. The second sealing protrusion 420 can be configured to seal between the first flange 120 and the second flange 220.

[0150] When the sealing member 400 is mounted on the first flange 120 and the second flange 220 is connected to the first flange 120, the first sealing protrusion 410 can be spaced apart from the second flange 220. When the sealing body 430 is mounted in the recess 123 and the second flange 220 is connected to the first flange 120, a gap g can be formed between the first sealing protrusion 410 and the second flange 220. When the sealing body 430 is mounted in the recess 123 and the second flange 220 is connected to the first flange 120, a gap g can be formed between the first sealing protrusion 410 and the inner surface 220a of the second flange 220. The first sealing protrusion 410 can be spaced apart from the inner surface 220a of the second flange 220. The first sealing protrusion 410 may not contact the inner surface 220a of the second flange 220. The first sealing protrusion 410 may not interfere with the inner surface 220a of the second flange 220.

[0151] For example, the first sealing protrusion 410 does not contact the second flange 220, but can be configured in a labyrinthine seal shape to impede the flow of washing water between the first flange 120 and the second flange 220. For example, eddies 500 may occur around the first sealing protrusion 410, and due to the resistance of the eddies 500, leakage of washing water around the first sealing protrusion 410 can be reduced.

[0152] In related technologies, as an example, a dishwasher may include: a first pipe, a second pipe capable of engaging with the first pipe, and a sealing member for sealing between the first and second pipes. A basket may be secured to the second pipe. The sealing member may include two or more sealing protrusions that contact the second pipe. Therefore, significant friction may occur when the second pipe engages with or disengages from the first pipe. That is, it may not be easy to connect the second pipe to the first pipe or to separate it from the first pipe. For example, separating the second pipe from the first pipe may require a large force and may impact the dishes contained in the basket. When the second pipe is separated from the first pipe, the dishes contained in the basket may fall or break. In related technologies, as another example, there are cases where O-rings are used to seal between the first and second pipes. In this case, the O-ring may easily separate from a groove formed in the first pipe. To make the O-ring less prone to separation, the groove may be formed deeper. However, when the groove is formed deeper, the flow rate of washing water guided by the first pipe may decrease as the size of the first pipe decreases. In related technologies, as another example, the sealing member can be configured to be insert-molded together with at least one pipe. That is, the sealing member can be integrally formed with at least one pipe. However, insert injection molding is more expensive than other methods, and the entire part needs to be replaced when the sealing member is damaged.

[0153] In contrast, according to this disclosure, the second sealing protrusion 410 of the sealing member 400 may contact the second conduit 200, but the first sealing protrusion 410 of the sealing member 400 may not contact the second conduit 200. Only one of the two sealing protrusions 410 and 420, the sealing protrusion 420, may contact the second conduit 200. Therefore, the frictional forces occurring when the second conduit 200 is mated to or detached from the first conduit 100 can be reduced. The second conduit 200 can be smoothly connected to and smoothly separated from the first conduit 100. When the second conduit 200 is separated from the first conduit 100, a large force is not required. When the second conduit 200 is separated from the first conduit 100, the impact transmitted to the tableware contained in the basket 52 can be minimized. Therefore, when the second conduit 200 is separated from the first conduit 100, the tableware contained in the basket 52 will not fall or break. For example, the length L1 of the sealing member 400 can be relatively longer than its thickness L2. Therefore, even due to the forces generated when the second pipe 200 is connected to or separated from the first pipe 100, the sealing member 400 will not easily deviate from the groove 123. Furthermore, the sealing member 400 can be detachably connected to the first pipe 100. When the sealing member 400 is damaged, only the sealing member 400 can be replaced, without replacing the entire pipe assembly 80. Maintenance and repair of the sealing member 400 are easy.

[0154] Figure 16 This is a cross-sectional view of a portion of a pipe assembly according to an embodiment. Figure 17 yes Figure 16 A magnified view of a portion of the image.

[0155] Figure 16 and Figure 17 The diagram illustrates a state where the second flange 220 of the second pipe 200 is not fully connected to the first flange 120 of the first pipe 100. For example, Figure 16 and Figure 17 The diagram illustrates a state where the second flange 220 is not fully connected to the first flange 120. For example, Figure 16 and Figure 17 The diagram can illustrate the state of the second flange 220 after it has moved following its connection with the first flange 120. For example, Figure 16 and Figure 17 The diagram illustrates the state after the second flange 220 is connected to the first flange 120 along the first direction A and has moved along the second direction B.

[0156] When using dishwasher 1, there may be situations where the first pipe 100 and the second pipe 200 are not fully connected. For example, the user may operate dishwasher 1 without fully inserting the basket 52 and the second pipe 200 into the inner tub 12. For example, even after the second flange 220 is fully aligned with the first flange 120 in the first direction A, the second pipe 200 may still move in the second direction B due to the water pressure of the washing water.

[0157] refer to Figure 16 and Figure 17 Even when the second flange 220 of the second pipe 200 is not fully connected to the first flange 120 of the first pipe 100, the second sealing protrusion 420 can still contact the second flange 220. Even when the second flange 220 of the second pipe 200 is not fully connected to the first flange 120 of the first pipe 100, the second sealing protrusion 420 can still be configured to seal between the first pipe 100 and the second pipe 200 by contacting the second flange 220. In other words, even when the second flange 220 of the second pipe 200 is not fully connected to the first flange 120 of the first pipe 100, the second sealing protrusion 420 can still prevent leakage of washing water. Finally, even if the user does not fully insert the basket 52 and the second pipe 200 into the inner liner 12, or if the second pipe 200 moves away from the first pipe 100 due to the water pressure of the washing water, the sealing effect of the sealing member 400 can be ensured.

[0158] According to this disclosure, the second sealing protrusion 420, positioned forward among the two sealing protrusions 410 and 420 of the sealing member 400, can contact the second flange 220. According to this disclosure, the first sealing protrusion 410, positioned rearward among the two sealing protrusions 410 and 420 of the sealing member 400, may not contact the second flange 220. With this structure, the size of the second flange 220 of the second pipe 200 can be set to be relatively small. Because the size of the second flange 220 is relatively small, the size of the basket 52 can be relatively large. For example, since the basket 52 is configured not to interfere with the second flange 220, the size of the basket 52 may be affected by the size of the second flange 220. Because the size of the basket 52 is relatively large, a large number of dishes can be loaded into the basket 52. Ultimately, the loading efficiency of the basket 52 is not reduced. For example, when the first sealing protrusion 410, positioned rearward among the two sealing protrusions 410 and 420 of the sealing member 400, contacts the second flange 220, the size of the second flange 220 can become relatively large. For example, based on... Figure 16In order for the first sealing protrusion 410 and the second flange 220 to contact each other, the second flange 220 needs to have a shape that extends further substantially in the first direction A. In this case, as the size of the second flange 220 increases, the size of the basket 52 fixed to the second pipe 200 decreases. Because the size of the basket 52 is relatively small, it is possible to load a small number of dishes into the basket 52. Ultimately, this may reduce the loading efficiency of the basket 52.

[0159] In summary, according to this disclosure, when the sealing member 400 is installed on the first flange 120, due to the inclination of the first flange 120, the first sealing protrusion 410 may not contact the second flange 220, while the second sealing protrusion 420 may contact the second flange 220. Therefore, the friction between the second flange 220 and the sealing member 400 can be reduced. The second pipe 200 and the basket 52 can be smoothly inserted into and / or pulled out of the inner tank 12. Even when the second pipe 200 is not fully connected to the first pipe 100, the sealing member 400 can prevent leakage of washing water. Because the size of the basket 52 can be set to be relatively larger than the second flange 220, the loading efficiency of the basket 52 can be maintained. The convenience of using the dishwasher 1 can be improved.

[0160] refer to Figure 17 The sealing member 400 may include a second recess 460 that is recessed between the second sealing protrusion 420 and the reinforcing portion 440.

[0161] Because the sealing member 400 includes a second recess 460 adjacent to the second sealing protrusion 420, the second sealing protrusion 420 can be formed flexibly. By means of the second recess 460, the second sealing protrusion 420 can be configured to bend. For example, the second sealing protrusion 420 can be bent toward the second recess 460. For example, the second sealing protrusion 420 can be bent toward the reinforcing portion 440.

[0162] Because the sealing member 400 includes the second recess 460, the second flange 220 of the second pipe 200 can more smoothly mate with the first flange 120 of the first pipe 100. For example, the second sealing protrusion 420 can be configured to be flexible when the second flange 220 is connected to the first flange 120 along the first direction A. For example, the second sealing protrusion 420 can be flexibly formed by means of the second recess 460. The frictional force occurring between the first flange 120 and the second flange 220 can be reduced, and the second flange 220 can smoothly mate with the first flange 120. Due to the friction occurring when the second flange 220 mates with the first flange 120, the sealing member 400 can be prevented from deviating from the groove 123 of the first flange 120. Due to the compression of the sealing member 400 by the second flange 220, the sealing member 400 can be prevented from deviating from the groove 123 and moving toward the first wall portion 121. In addition, when the second flange 220 is connected to the first flange 120, the sealing member 400 is prevented from being twisted because it is squeezed by the second flange 220.

[0163] Because the sealing member 400 includes the second recess 460, the second flange 220 of the second pipe 200 can more smoothly disengage from the first flange 120 of the first pipe 100. For example, when the second flange 220 separates from the first flange 120 along the second direction B, the second sealing protrusion 420 can be flexibly formed by means of the second recess 460. The frictional force occurring between the first flange 120 and the second flange 220 can be reduced, and the second flange 220 can smoothly disengage from the first flange 120. Because the second recess 460 is formed around the second sealing protrusion 420, a smaller force is required to pull the second flange 220 from the first flange 120.

[0164] In summary, because the second notch 460 is formed between the second sealing protrusion 420 and the reinforcing portion 440, a predetermined space can be ensured between the second sealing protrusion 420 and the reinforcing portion 440. Therefore, the second sealing protrusion 420 can move more flexibly, and the second conduit 200 can be smoothly connected to and smoothly separated from the first conduit 100.

[0165] Figure 18 This is a cross-sectional view of a portion of a pipe assembly according to an embodiment.

[0166] Compared to the aforementioned sealing member 400, Figure 18 The sealing member 400a shown may include only the second sealing protrusion 420. The sealing member 400a may be substantially the same as the sealing member 400, except that the sealing member 400a does not include the first sealing protrusion 410. In the description... Figure 18When referring to the sealing member 400a, the same reference numerals may be assigned to the same member as described above, and its detailed description may be omitted. For ease of explanation, the second sealing protrusion 420 may be referred to as the sealing protrusion 420, and the second recess 460 may be referred to as the recess 460.

[0167] The sealing member 400a may include a sealing body 430 that can be mounted on the outer surface of the first flange 120. The sealing body 430 may be detachably mounted in a groove 123 of the first flange 120.

[0168] The sealing member 400a may include a sealing protrusion 420 projecting from the sealing body 430. The sealing protrusion 420 may project from the sealing body 430 along a third direction C, which is the radial direction of the sealing member 400. The sealing protrusion 420 may be configured to project further than the notch 460 towards the inner surface 220a of the second flange 220. The sealing protrusion 420 may be configured to project further than the reinforcement portion 440 towards the inner surface 220a of the second flange 220. The sealing protrusion 420 may be formed on the front end of the sealing member 400a.

[0169] When the sealing member 400a is installed in the groove 123 and the second flange 220 is abutted against the first flange 120, the sealing protrusion 420 can be configured to contact the second flange 220. The sealing protrusion 420 can contact the inner surface 220a of the second flange 220. The sealing protrusion 420 can interfere with the inner surface 220a of the second flange 220. The sealing protrusion 420 can prevent washing water from flowing between the first flange 120 and the second flange 220. The sealing protrusion 420 can prevent washing water from leaking between the first flange 120 and the second flange 220. The sealing member 400a may include a reinforcing portion 440. The reinforcing portion 440 may be disposed behind the sealing protrusion 420. The reinforcing portion 440 may protrude from the sealing body 430. For example, the reinforcing portion 440 may protrude from the sealing body 430 along a third direction C. However, it can be stated that the reinforcing portion 440 is formed because at least a portion of the sealing body 430 is formed to be relatively thick. For example, a portion formed to be thicker than the predetermined thickness of the sealing body 430 can be referred to as a reinforcing portion 440. The reinforcing portion 440 can be configured to enhance the strength of the sealing member by being formed to be thicker than the predetermined thickness.

[0170] The sealing member 400a may include a notch 460. The notch 460 may be configured adjacent to the sealing protrusion 420. The notch 460 may be located behind the sealing protrusion 420. The notch 460 may be configured such that the sealing member 400a is recessed between the sealing protrusion 420 and the reinforcing portion 440. However, it can be stated that the notch 460 is formed because at least a portion of the sealing body 430 is formed to be relatively thin. For example, a portion formed to be thinner than a predetermined thickness of the sealing body 430 may be referred to as the notch 460. Because the sealing member 400a includes the notch 460, the sealing protrusion 420 can be formed more flexibly. Therefore, the second conduit 200 can be smoothly connected to and smoothly separated from the first conduit 100.

[0171] The dishwasher according to an embodiment may include: an inner tub 12; a first conduit 100 disposed inside the inner tub to guide washing water, and the first conduit 100 including a first flange 120; a second conduit 200 configured to guide washing water supplied from the first conduit, and the second conduit 200 including a second flange 220 configured to be connectable to the first flange along a first direction A; and a sealing member 400 configured to seal between the first flange 120 and the second flange 220. The sealing member 400 may include a sealing body 430 mountable on an outer surface of the first flange. The sealing member 400 may include a first sealing protrusion 410 projecting from the sealing body. The sealing member 400 may include a second sealing protrusion 420 configured to be spaced apart from the first sealing protrusion along a second direction B opposite to the first direction, and the second sealing protrusion 420 projecting from the sealing body. The sealing member 400 may include a reinforcing portion 440 formed between the first sealing protrusion 410 and the second sealing protrusion 420. The sealing member 400 may include a recess 460 disposed between the second sealing protrusion 420 and the reinforcing portion 440.

[0172] The second sealing protrusion 420 can be configured to bend toward the notch 460 when the second flange 220 is connected to the first flange 120 along the first direction A.

[0173] The first flange 120 may include: a first wall portion 121; a second wall portion 122, the second wall portion 122 being spaced apart from the first wall portion 121 along a second direction B; and a groove 123 formed between the first wall portion and the second wall portion, and the sealing body of the sealing member being mounted in the groove 123. The groove 123 may have a ramp by widening along the second direction.

[0174] When the sealing body is installed in the groove, the first sealing protrusion 410 can be positioned adjacent to the first wall portion 121. When the sealing body is installed in the groove, the second sealing protrusion 420 can be positioned adjacent to the second wall portion 122.

[0175] When the sealing body is installed in the groove and the second flange is connected to the first flange, the second sealing protrusion 420 can be configured to contact the inner surface of the second flange 220.

[0176] When the sealing body is installed in the groove and the second flange is connected to the first flange, a gap g can be formed between the first sealing protrusion 410 and the inner surface of the second flange 220.

[0177] The first flange 120 may include a hollow shape. The outer diameter D1 of the first side 1231 of the groove adjacent to the first wall portion 121 may be smaller than the outer diameter D2 of the second side 1232 of the groove adjacent to the second wall portion 122.

[0178] The first sealing protrusion 410 and the second sealing protrusion 420 can be configured to be symmetrical with respect to the vertical center line V or the radial center line of the sealing member.

[0179] When the sealing body is installed in the groove, the second sealing protrusion 420 can be configured to protrude further than the first sealing protrusion 410 relative to the horizontal center line H of the sealing member.

[0180] The first sealing protrusion 410 and the second sealing protrusion 420 can be configured to protrude further from the sealing body 430 than the reinforcing portion 440.

[0181] The sealing member may include an annular shape. The length L1 of the sealing member along the second direction may be longer than the thickness L2 of the sealing member along the third direction, which is the radial direction.

[0182] The second sealing protrusion 420 may include an inclined portion 421 configured to taper or narrow along the second direction B.

[0183] The first flange 120 may include a first chamfer 125, which is configured to taper or narrow from the second wall portion along a second direction. The second flange 220 may include a second chamfer 225, which is configured to correspond to the first chamfer when the second flange 220 is attached to the first flange.

[0184] The second pipe 200 can be configured to be connected to the first pipe 100 by being inserted into the inner liner 12. The second pipe 200 can be configured to be separated from the first pipe 100 by being withdrawn from the inner liner 12.

[0185] The dishwasher may also include a basket 52 configured to hold tableware in an inner liner 12, and the basket 52 is configured to be fixed to a second conduit 200 for movement together with the second conduit 200.

[0186] A dishwasher according to an embodiment may include: an inner tub 12; a spray rotor 42 configured to spray washing water into the interior of the inner tub; a reservoir 70 configured to store washing water from the interior of the inner tub; and a first conduit 100 including a first frame 110 and a first flange 120, the first frame 110 being configured to guide washing water supplied from the reservoir, the first flange 120 being configured to allow washing water guided by the first frame to flow out, and the first flange 120 having a channel for the washing water to flow out from the first frame. The first flange 120 has an increased outer diameter due to its forward projection; a second conduit 200, including a second flange 220 and a second frame 210, the second flange 220 being configured to engage with the first flange to introduce washing water flowing from the first flange, and the second frame 210 being configured to extend forward from the second flange to guide the washing water introduced through the second flange to the jet rotor; and a sealing member 400 or 400a configured to seal between the first flange 120 and the second flange 220.
