[0034] First, refer to Figure 1 to Figure 4 , The first embodiment will be described. figure 1 The illustrated washing machine 10 includes an outer box 11, a water tank 12, a rotating tank 13, a door 14, and a motor 15. In addition, with figure 1 The left side is the front side of the washing machine 10, with figure 1 The right side of is the rear side of the washing machine 10. In addition, the vertical lower side of the installation surface side of the washing machine 10 is the lower side of the washing machine 10, and the vertical upper side opposite to the installation surface is the upper side of the washing machine 10.
[0035] The washing machine 10 is a so-called horizontal axis type drum-type washing machine in which the rotating shaft of the rotating tank 13 is horizontal or descends and inclines backward. The outer box 11 constitutes the outer shell of the washing machine 10. The outer box 11 is formed of, for example, a steel plate in a substantially rectangular box...

[0082] Next, refer to Figure 5 , The second embodiment will be described.
[0083] In the solenoid valve 40 of the second embodiment, the second throttle 53 has a protrusion 55 instead of the protrusion 54. The protruding part 55 is a male screw whose tip is formed in a tapered shape similarly to the protruding part 54. In other words, the tip of the protrusion 55 is formed in a tapered shape and inserted into the flow path 432. In addition, an external thread is formed on the outer peripheral portion of the protrusion 55. In addition, a base end portion of the protrusion 55, that is, a side exposed to the outside, is formed with, for example, a hexagonal hole for a tool. Furthermore, the second throttle 53 is formed by screwing a plurality of protrusions 55 into the flow path forming member 43 from the outside of the flow path forming member 43. In this case, four protrusions 55 are removed from the flow path. The outer side of the forming member 43 is formed by screwing int...

[0086] Next, refer to Figure 6 to Figure 10 , The third embodiment will be described.
[0087] Such as Image 6 As shown, the solenoid valve 40 of the third embodiment has a second throttle portion 60 instead of the second throttle portion 53 of the first embodiment. The second throttle portion 60 is configured separately from the flow path forming member 43, that is, configured as a separate member. The second throttle portion 60 is inserted into the constriction portion 511 from the entrance side of the constriction portion 511 of the first throttle portion 51 and is provided at the boundary portion between the constriction portion 511 and the smallest diameter portion 512.
[0088] At the boundary portion between the constricted portion 511 and the smallest diameter portion 512, a step portion 513 for locking the second throttle portion 60 is formed. Here, the flow velocity is increased by the constricted portion 511, whereby a high-pressure load acts on the second throttle p...
