  • the water guide 140 to which a check valve of the present invention is to be coupled, is U-shaped and disposed along an inner surface of the tub 110 .
  • the water guide 140 is formed with a nozzle holder connecting portion 143 at a middle for coupling with the nozzle holder 151 .
  • the nozzle holder connecting portion. 143 includes support bosses 142 and a water outlet port 141 . When assembled, the support bosses 142 couples with a check valve (refer to 200 in FIG. 3 ).
  • the water outlet port 141 is formed under the support bosses 142 with a predetermined diameter and height.
  • the nozzle holder 151 when assembled, the nozzle holder 151 is supported by the support bosses 142 , and washing water is supplied to the nozzle holder 151 from the water guide 140 through the water outlet port 141 .

  • the check valve 200 includes a gasket unit having a gasket support 220 and a gasket 210 .
  • the gasket support 220 is inserted into the nozzle holder 151 with its front facing the nozzle holder 151 .
  • the gasket 210 is made of rubber and fitted to a back of the gasket support 220 to prevent leakage.
  • the gasket support 220 includes an upper inlet port 230 and a lower inlet port 240 to introduce washing water into the nozzle holder 151 . Since the water outlet port 141 of the water guide 140 is selectively coupled to the upper inlet port 230 and the lower inlet port 240 , the inlet ports 230 and 240 may have the same diameter. The selective coupling between the water outlet port 141 and the inlet ports 230 and 240 will be fully described later.

  • the flap 250 is sized to fully cover the lower inlet port 240 .
  • the flap 250 couples with flap support unit that are protruded from a front of the gasket support 220 .
  • the flap support unit includes flap support arms 260 having protrusions 261 .
  • the flap support arms 260 face each other and are located a predetermined distance from each other to support both sides of the flap 250 .
  • the Protrusions 261 are inwardly extended from inner sides of the flap support arms 260 to face each other.
  • the flap 250 includes a protrusion receiving portion such as a coupling hole 251 defined in an upper end to receive the protrusions 261 of the flap support arms 260 .

  • the lower end of the lower inlet port 240 is extended forward more than that of the upper inlet port 230 . That is, the end of the lower inlet port 240 is angled with respect to the gasket support 220 . Therefore, when the flap 250 closes the lower inlet port 240 , the flap 250 is suspended at an angle to the vertical, such that the contact between the flap 250 and the lower inlet port 240 can be more securely maintained by the weight of the flap 250 without a gap. If the end of the lower inlet port 240 is not sloped, the lower inlet port 240 may not be securely closed by the flap 250 . For example, if the dish washer 100 is placed on a sloped surface, a gap may be defined between the flap 250 and the lower inlet port 240 when the flap 250 closes the lower inlet port 240 .

  • the nozzle holder 151 can be coupled to the water guide 140 at different heights. To couple the nozzle holder 151 to the water guide 140 at a relatively higher position, the first hole 310 is fitted to the higher of the support bosses 141 , and therefore the water outlet port 141 of the water guide 140 communicates with the third hole 330 and the lower inlet port 240 .
  • the first hole 310 is fitted to the lower of the support bosses 141 , and therefore the water outlet port 141 of the water guide 140 communicates with the second hole 320 and the lower inlet port 230 .
  • FIG. 4 is a side view showing a check valve installed in a nozzle holder according to the present invention.
  • the check valve 200 is installed at an end of the nozzle holder 151 , and the lower inlet port 240 communicates with the nozzle holder 151 .
  • the nozzle holder 151 is coupled to the water guide 140 with the lower inlet port 240 communicating with the water outlet port 141 . Washing water flows from the water outlet port 141 to the lower inlet port 240 , and pushes the flap 250 to rotate it about the flap support arms 260 in an upward direction. When the flap 250 is fully rotated by the washing water, the lower edge of the flap 250 makes contact with the inner wall of the nozzle holder 151 to prevent the washing air from reversely flowing toward the upper inlet port 230 . Therefore, the washing water can flow from the water outlet port 141 to the nozzle holder 151 through the lower inlet port 240 without backflow through the upper inlet port 230 .
  • the coupling of the nozzle holder 151 to the water guide 140 at a relatively lower position will now be described.
  • the nozzle holder 151 is coupled to the water guide 140 with the upper inlet port 230 communicating with the water outlet port 141 .
  • Washing water flows from the water outlet port 141 to the nozzle holder 151 through the upper inlet port 230 , and pushes down the flap 250 to close the lower inlet port 240 . That is, the flow of the washing water presses the flap 250 against the lower inlet port 240 and thereby the lower inlet port 240 can be securely closed to prevent backflow therethrough.
  • the washing water further flows from the nozzle holder 151 to the upper nozzle 130 .
  • the flap 250 is rotatably coupled with the protrusions 261 of the flap support arms 260 .
  • the position of the flap 250 is determined depending on which inlet port communicates with the water outlet 141 .
  • the check valve 200 does not require a hinge shaft for coupling the flap 250 with the flap support arms 260 . That is, by forming the protrusions 261 integral with the flap support arms 260 , the manufacturing process and cost can be simplified and reduced.
  • the water leakage can be prevented during the washing water flows from the water guide to the upper nozzle. Also, since the check valve has a simple structure, the manufacturing process and cost can be simplified and reduced. Therefore, the present invention can be applied to various industrial fields.
