[0002]

2. Description of the Related Art Conventionally, a multi-way valve used for a device requiring a change of a flow path such as a water purifier is disclosed in JP-A-9-17067.
No. 0, the displacement of the pressing member,
It is known that a valve body contact member is transmitted to a valve body contact member via a movable member, and the valve body contact member displaces the valve body to switch between opening and closing of a flow path. The open / closed state of the flow path is maintained by maintaining the stop position of the movable member by the temporary stop means.

As the temporary stopping means, a mechanism as shown in FIG. 1 used for a ball-point pen or the like is generally used, and the open / close state of the flow path can be confirmed by the stop position of the pushing member. However, it is difficult to fix the pushing member to the temporarily stopped movable member with such a temporary stopping means, and there is a problem that the pushing member moves from the stop position even when the movable member is stopped.

That is, in the structure shown in FIG. 1, the valve element 200 is displaced by the contact member 201 to switch the opening and closing of the flow path, and the operation of the pushing member 202 is controlled by the reciprocating cam 203, the rotating cam 204, and the movable member. The light is transmitted to the contact member 201 via the connection member 205. The movable member 2 urged by the contracted spring 206
05 suppresses the movement of the spring 206 in the biasing direction by the rotating cam 204 supported by the shallow groove 208 of the guide cylinder 207, and temporarily stops the contact member 201. But,
In this state, even if the movement of the movable member 205 is suppressed,
The pushing member 202 that contacts the rotating cam 204 via the reciprocating cam 203 can move in the arrow direction F, and easily moves when vibration or impact is applied or the multi-way valve itself is inclined. As a result, the open / closed state of the flow path cannot be confirmed.

[0005]

The switching state of the flow path will be described below.

FIG. 14A shows a temporary stopping means, in which the reciprocating cam 7 is inserted into the deep groove 62 and the shallow groove 63 of the guide cylinder 61.
One reciprocating cam ridge 71a is inserted to the back, and then the rotating cam ridge 81a of the rotating cam 81 is inserted into the deep groove 62. The rotating cam 81 is urged by the spring 91 via the reciprocating shaft 42. The state is shown. The reciprocating cam 71, the rotating cam 81, and the reciprocating shaft 42 are all temporarily stopped.
The reciprocating cam 71 is urged by the spring 91 to prevent backward movement (right side in FIG. 14) during use, and is stopped at the front end of the guide cylinder 61 so that forward movement is stopped. (See FIG. 5). At this time, the push button 10
The backward movement is suppressed by the reciprocating cam 71, and the push button 10
Is restricted by the stopper 6b, so that forward movement is suppressed. Therefore,
It is possible to prevent the push button 10 from moving due to vibration, impact, inclination, or the like.

In this state, the contact member 41 is at the first stop position P1 via the reciprocating shaft 42, and the valve case 7
Is closed by the first ball 11, and the second outlet 32 is open. Raw water flowing from the inflow port 21 in this state passes through the second outflow port 32, is supplied to the filtration unit 3 through the filtration unit supply port 19, is filtered, and then flows out as purified water.

Here, when the push button 10 is pressed, the reciprocating cam 71
Slides in the direction of the valve case 7 in the guide cylinder 61 and engages with the inclined tip of the reciprocating cam ridge 71a.
The rotary cam 81 slides via 1a, and the reciprocating shaft 42 and the contact member 41 move toward the second stop position P2. FIG.
As shown in (b), when the rotary cam ridge 81a passes through the deep groove 62, the rotary cam ridge 81a is moved along the inclined surface at the tip of the guide ridge 65 and the reciprocating cam ridge 71a by the bias of the spring 91. As a result, the rotating cam 81 rotates in the circumferential direction. When the pressing force of the push button 10 is released, the rotating cam ridge 81a slides along the inclined tip of the shallow groove 63 due to the bias of the spring 91, and as a result, the rotating cam 81 further rotates in the circumferential direction. FIG. 14
The position shown in (c) is reached. The rotating cam protrusion 81 a that cannot be inserted into the shallow groove 63 is locked by the inclined tip of the shallow groove 63 and the side surface of the guide protrusion 65. Further, at this time, since the rotating cam 81 and the reciprocating shaft 42 are urged by the spring 91, they are prevented from moving backward during use, and temporarily stopped. The rotation cam 81 prevents the reciprocating cam 71 and the push button 10 from moving backward (to the right in FIG. 14). Further, an L-shaped leaf spring 96 fixed to the housing 6
Engages with the notch 97 formed in the push button 10 to prevent the push button 10 from moving forward and backward. Therefore, it is possible to prevent the push button 10 from shifting when the shock or vibration is applied to the valve body 2 or the valve body 2 itself is inclined. Then, the operator can easily confirm the open / closed state of the flow path by looking at the symbol written on the display board 92 from the window 10 b opened on the upper surface of the push button 10.

In this state, the contact member 41 is stopped at the second stop position P2 via the reciprocating shaft 42, the first outlet 31 is open, and the second outlet 32 is The closed state is maintained. In this state, the inlet 2
The raw water flowing from 1 passes through the first outlet 31 and is rectified by the rectifying member 29, and then discharged from the shower discharge port 18.

When the push button 10 is pressed again, the reciprocating cam ridge 71a sliding in the shallow groove 63 causes the rotating cam ridge 81a to slide.
Is pushed out to a position along the inclined tip of the guide ridge 65. Thereafter, when the pressing force of the push button 10 is released, the rotating cam ridge 81a slides along the inclination of the tip of the guide ridge 65 by the bias of the spring 91, and as shown in FIG. The rotating cam protrusion 81a slides into the next deep groove 62, and the state is the same as the initial state, that is, the contact member 41 is stopped at the first stop position P1.

[0037]

As described above, according to the multi-way valve of the present invention, since the push member is provided with the stopping means, vibration or impact is applied to the multi-way valve or the multi-way valve is inclined. In addition, it is possible to prevent the push member from shifting from the temporarily stopped position, and as a result, it is possible to easily and accurately confirm the open / closed state of the flow path based on the stop position of the push member.

By providing the contact member, the movable member, and the temporary stop means, the displacement of the push member is transmitted to the contact member via the movable member, and the contact member moves the valve body to move the valve body. It is possible to switch the open / close state of the outlet provided in the apparatus, and to maintain the state of the flow path. When the push member is pushed again, the open / close state of the outlet can be switched again in a similar manner.

In addition, since the parking means includes an urging member attached to one of the housing, the valve case, and the pushing member and abutting against the other, the pushing member is displaced from the position where the pushing member is once stopped. Can be more reliably prevented,
Also, when a sphere is included in addition to the urging member, the sphere urged by the urging member abuts, so that the pushing member can be effectively prevented from moving. Further, it is possible to more surely prevent the pushing member from moving by applying a force in a direction perpendicular to the moving direction of the pushing member. Also, when the stopping means includes a concave portion or a notch and an elastic member fitted thereto, the concave portion or the notch engages with the elastic member. Can be prevented.

When such a multi-way valve of the present invention is used in a water purifier provided with a filtration section for filtering raw water, raw water can be selectively filtered, and the stop position of the pushing member can be determined by looking at the stop position of the pushing member. The open / closed state of the filtration channel can be accurately confirmed.
