Abstract

PROBLEM TO BE SOLVED: To provide an energy conservation type single lever type hot/cold water mixing plug which is facilitated for use in a water sparing mode and for adjustment of a hot/cold water mixing ratio and which does not use spare hot water, although the single lever type hot/cold water mixing plug of the prior art capable of being fully opened even at any horizontal rotary position has defects: that the user sets the horizontal rotary position of the single lever at a central position of the unconsciously easily operable hot/cold water mixing position so that the hot water is easily wasted; and that the vertically rotational range for the discharge amount adjusting of the single lever is so narrow that the discharge amount is easily changed highly by a slight vertical rotation.SOLUTION: By limiting the horizontal rotary position of a fully closable single lever 8 capable of fully closing a hot/cold water mixing plug, the user is caused to be always conscious of a hot water mixing ratio, and to set a lower limit discharge rate at a fully unclosable horizontal rotary position.

Description

  The present invention relates to a single lever type hot and cold water mixing tap that adjusts a hot water mixing ratio and a discharge amount by horizontal and vertical rotation of a single lever.

The single lever type hot and cold water mixing tap is a movable valve body that is placed on the top of the fixed valve body on the main body of the hot and cold water mixing stopper and is slidable. This is a hot and cold water mixing tap that adjusts the hot water and water mixing ratio and the discharge amount, and since it is easy to operate, various single lever type hot and cold water mixing taps are often used.
However, since the user often places the horizontal rotation position of the single lever near the central position where it is easy to operate unconsciously, it is used near the central position, which is the hot water mixing position, at the start of use, etc. There is a fault that is easy to do. In addition, since the vertical rotation angle range for adjusting the discharge amount is narrow and the discharge amount changes greatly by a slight vertical rotation, there is a drawback that it is easy to use with an excessive discharge amount.
For these drawbacks, Patent Documents 1 and 2 disclose that the shape of the water inlet valve / hot water inlet valve of the fixed valve body and the hot water control valve port of the movable valve body are changed to a single lever when fully closed. Although a structure has been proposed in which water is discharged first at the start of the next use even if it is in the center position, it is difficult to adjust the hot / cold water mixing ratio because the adjustment angle range of the hot / cold water mixing ratio is smaller than the conventional structure. Leakage due to uneven sliding wear due to the fact that it is difficult to secure a sufficient discharge volume due to the reduced valve opening area, and uneven pressing force is applied to the movable valve body due to the uneven area and arrangement of the valve opening. There are new drawbacks.
Further, Patent Documents 3 and 4 have a proposal to add a water-saving mode function for temporarily limiting the discharge amount to a predetermined upper limit discharge amount or less by limiting the vertical rotation angle in the opening direction of the single lever. There is a drawback in that some switching operation is required both for switching from the use mode to the water-saving mode and for switching from the water-saving mode to the normal use mode.
Further, in Patent Documents 5 and 6, by providing a guide surface on the single lever base, the hot and cold water mixing plug body, etc., the single lever is fully closed at the horizontal rotation position where only the water is discharged when the single lever is fully closed. There is a proposal to forcibly avoid unintentional use of hot water by making it in a horizontal rotation position where only water is discharged without needing to be aware of it next time. Since the guide surface for guiding the single lever is provided between the moving position and the horizontal rotation position for discharging only water, the following disadvantages are present.
(1) By providing the guide surface, the lower limit discharge amount at each horizontal rotation position increases from the horizontal rotation position at which only water is discharged toward the horizontal rotation position at which only hot water is discharged, thereby increasing the hot water mixing ratio. The allowable discharge amount range is limited to the large capacity side. For this reason, although there is an effect of not wasting hot water at the start of use, the discharge amount is regulated by the guide surface at almost the horizontal rotation position (horizontal rotation position for discharging only hot water and hot water mixed water) during use. There is a basic drawback that cannot be reduced to a small amount below the amount. For this reason, the above water-saving mode function cannot be added.
(2) The fully closed position is limited to a horizontal rotation position that discharges only water, and in a hot and cold water mixing tap for a bathtub, etc., it cannot be fully closed at a horizontal rotation position of a hot and cold water mixing ratio, Since it is forcibly guided to a horizontal rotation position that discharges only water, there is a need for resetting the horizontal rotation position of the hot and cold water mixing ratio that is frequently used during repeated use for a short time.
(3) When the single lever is operated in the direction of closing the discharge amount (closed direction) at the horizontal rotation position for discharging only hot water or hot / cold water, the allowable range of vertical rotation of the single lever is narrow and it is easy to contact the guide surface. Therefore, the single lever moves horizontally in the direction of decreasing the hot water mixing ratio (the direction in which only water is discharged), and the hot water mixing ratio changes unintentionally, so the hot water mixing ratio must be reset. Will occur.
Connected to a hot water / water mixing tap for a shower with a shower head provided at the discharge port shown in Patent Documents 7 to 10, a hot water / water mixing tap with a branch valve for switching between a discharge port for a faucet and a discharge port for a shower head, a solar water heater and a water heater The hot water mixing tap with a solar water heater and the hot water mixing tap with a water purification device used in connection with a water purification device have the above-mentioned drawbacks corresponding to the configuration.
Patent Document 11 includes a water-stop regulating member that prevents a fully-closed operation in a state in which the operation lever is rotated to a higher temperature side than a predetermined first high temperature position, so that the temperature of the high temperature at the start of use is increased. Although it is described that the hot water is prevented from being unexpectedly discharged, the function described in Patent Documents 1, 2, 5, and 6 that prevents unintentional waste of hot water at the start of use is also patented. There is no function of the water-saving mode that prevents the use of the discharge amount more than necessary described in Documents 3 and 4, and safety is improved, but there is no function of energy saving and water saving.
Patent Document 12 provides an engagement member that suppresses the opening / closing operation of the operation lever during the opening operation and during the closing operation between the upper outer peripheral surface of the mixing stopper main body and the cap lower portion of the operation lever. It is described that the water hammer phenomenon at the time of the fully-closed operation is prevented and the contamination due to the splashing of the hot water at the time of the fully-opened operation is prevented. There is no function to prevent this, and there is no function of water-saving mode that prevents it from being used at an unnecessarily large discharge amount.

Comprising;
The hot water / water mixing tap is characterized in that the water-saving mode closed-side facing portion is provided in at least a part of a horizontal rotation range in which water of the closed-side facing portion or hot-water mixed water can be discharged.

The second invention is
The water-saving mode close-side facing portion holds the movable valve body at the position of the fixed valve body from which a predetermined amount of water-saving mode lower limit discharge amount is discharged when the close-side contact portion comes into contact. It is characterized by.

The third invention is
The water-saving mode closed-side facing portion ensures a water-saving mode lower limit discharge amount by making a vertical rotation angle of the operating body constant when the closed-side contact portion comes into contact. .

The fourth invention is
The fully-closeable close-side facing portion is limited to a part or all of a horizontal rotation range in which only water in the close-side facing portion of the hot-water / water mixing tap main body can be discharged.

The fifth invention is
The water-saving mode closed-side facing portion is provided in the entire horizontal rotation range capable of discharging only hot water in the closed-side facing portion of the hot-water mixing tap main body.

The sixth invention is

The tenth invention is
The protrusion length of the opening side contact portion provided on one of the opening side surface of the single lever and the opening side surface of the operating body is adjustable.

According to the first to sixth aspects, the following effects are obtained by the respective closed-side facing portions.
(1) In the hot and cold water mixing plug of the present invention, the horizontal rotation position at which the water can be fully closed is limited by one or a plurality of fully closeable close side facing portions corresponding to a preset hot water / water mixing ratio. Therefore, in order to fully close the hot and cold water mixing tap of the present invention, the single lever must be horizontally rotated to the horizontal rotation position of this hot and cold water mixing ratio, and can be fully closed in all horizontal rotation ranges of the single lever. Unlike the case of using a hot / cold mixing tap or a hot / cold mixing tap that is guided to a horizontal rotation position that discharges only water unconsciously during the fully-closed operation of Patent Documents 5 and 6, the current hot / cold mixing ratio is always maintained during use. Because you are conscious, you can save energy without unconsciously wasting hot water not only at the start of use but also during use.
(2) If the single lever is operated in the closing direction by the water-saving mode close-side facing part, a useful, predetermined amount of the lower limit discharge amount for the water-saving mode can be easily discharged without mode switching operation. Don't waste water. This eliminates the difficulty of setting a small discharge amount, which is a drawback of the single lever type hot and cold water mixing tap. In addition, without mode switching operation, it is possible to use both the water-saving mode that can discharge a predetermined amount of lower limit discharge amount for water-saving mode and the normal use mode that can discharge a larger flow rate than the lower limit discharge amount for water-saving mode. Becomes simple.
(3) Since the horizontal rotation position that can be fully closed is limited, a conscious full closing operation is performed. Therefore, there is no fear of leaving a leak due to unintentional lever operation, and hot water is not wasted. This eliminates the possibility of wasting hot / hot water in a hot water storage tank or the like that uses electric power at night.
(4) In the horizontal rotation range in which the water-saving mode close-side facing portion is provided, a water hammer phenomenon due to a sudden full-close operation does not occur.

(5) If the fully-closeable close-side facing portion is limited to the entire horizontal rotation range that discharges only water, the fully-closed operation is limited to the horizontal rotation range that discharges only water. Unnecessary waste of hot water at the start can be forcibly eliminated.
If the fully-closeable close side facing part is limited to a part of the horizontal rotation range that discharges only water, it is forcibly forced to waste hot water at the start of use by the fully-closeable close side facing part. In addition to the effect of eliminating water, hot water and hot water with a predetermined water-saving mode lower limit discharge amount for water-saving mode are provided even when in use by providing a water-saving mode closed-side facing part in the horizontal rotation range that discharges only water Can be prevented.
If the entire horizontal rotation range that discharges only hot water is equipped with a water-saving mode close-side facing part, it cannot be fully closed in this horizontal rotation range, and there is a risk of burns due to unexpectedly hot water being discharged at the start of use. There is no.
(6) The position of the movable valve body with respect to the fixed valve body is different from the case of the guide surfaces described in Patent Documents 5 to 6 when the closing side abutting part comes into contact with the closing side facing part by the closing operation of the single lever. In addition, since the vertical rotation angle of the operating body is maintained without change, there is no unintentional change in the hot / cold water mixing ratio, and it is free from the complexity of resetting the hot / cold water mixing ratio.
In addition, since there is no guide surface and the range of the discharge amount is not limited to the large capacity side, the discharge amount in a practically necessary range can be discharged even in the horizontal rotation range provided with the water-saving mode close-side facing portion.
(7) The water-saving mode lower limit if the closing-side facing member provided with the water-saving mode closing-side facing portion is attached to a part or all of the closed-side facing portion of the hot and cold water mixing plug main body so as to be vertically movable. The discharge amount can be changed easily, and if it is mounted so that it can be rotated horizontally, it is possible to easily change the horizontal rotation position that can be fully closed (change the mixing ratio of hot water and water).

(8) Since there are few restrictions on the shape and arrangement of the water inlet valve / hot water inlet valve port of the fixed valve body and the hot water control valve port of the movable valve body, it is easy to secure the valve port area and obtain a sufficient flow rate. It is done.
(9) Since there are few restrictions by arrangement | positioning of the valve opening of a fixed valve body and a movable valve body, and the horizontal rotation range of the hot water mixing ratio adjustment of a single lever can be ensured enough, hot water mixing ratio is easy to adjust.
(10) Since it is possible to balance the opening area and position of the water inlet valve port and the hot water inlet valve port of the fixed valve body, the biased pressure does not act on the movable valve body in the closed state, and sliding wear does not occur. There are no problems such as poor watertightness of sliding parts due to uniformity and water leakage of watertight packing.

According to the seventh aspect of the present invention, the following effects are achieved by the closed contact portion or the water-saving mode closed facing portion that moves forward and backward by elasticity.
(1) Hold the single lever by hand in the up / down rotation position where it can be fully closed even in the horizontal rotation position where the water-saving mode close-side facing part is provided and the lower limit discharge amount for water-saving mode is set Can be fully closed while holding.
(2) Since the lower limit discharge amount for water-saving mode is automatically discharged at the same mixing ratio of hot water and water after release, there is no need to set a small discharge amount for rinsing, etc., and the lower limit discharge amount for water-saving mode Rinse washing with a small discharge amount can be performed.

According to the eighth aspect of the present invention, the water-saving mode lower limit discharge amount can be easily adjusted to a desired discharge amount by adjusting the protrusion length of the closed-side contact portion or the water-saving mode close-side facing portion. Thus, the desired discharge amount can be discharged by adjusting the protrusion length in the contact state of the closed contact portion or by operating the single lever in which the protrusion length of the close contact portion is adjusted in the closing direction. Therefore, it is possible to greatly improve the difficulty of adjusting the small discharge amount, which is the greatest drawback of the single lever type hot and cold water mixing tap.
If the lower limit discharge amount for water-saving mode is temporarily reduced to zero by adjusting or switching the protrusion length, all the water can be moved at any horizontal rotation position without changing the hot water mixing ratio even if the single lever is not held by hand. Closing and discharging can be repeated frequently.

  According to the ninth aspect of the present invention, the opening side abutting portion that moves forward and backward by elasticity can easily be used with an upper limit discharge amount smaller than the maximum discharge amount when fully opened without mode switching operation. Thereby, it is possible to easily use the lower limit discharge amount, the appropriate amount range between the lower limit discharge amount and the upper limit discharge amount, and the upper limit discharge amount. Further, if it is held by hand, it can be fully opened even though it is temporary.

  According to claim 10, by adjusting the protrusion length of the open-side contact portion, the upper limit discharge amount can be easily adjusted, and it is possible to cope with a narrow appropriate amount range set by the upper limit discharge amount and the lower limit discharge amount. It is easy to repeatedly use a desired discharge amount.

According to claims 1 to 10, the following hot and cold water mixing plug having the above-described effects can also be realized.
(1) Solar water heater combined hot water mixer tap that can be used by switching between the main water heater and solar water heater (2) Beverage container combined use hot water mixer tap that can be used by switching between tap water system and beverage container (4) Hot water mixer tap with branch valve that can be used by switching faucet and shower head (5) Equipment combined use hot and cold water mixer tap

Water supply route Watertight communicating packing 12 for communicating the hot water supply path, and the O-ring 13 for watertight between the cartridge case 3 and the mixing faucet body case 1 is provided.

  In the single lever type hot and cold water mixing tap of this embodiment, in order to facilitate the replacement of repair parts, the internal parts can be replaced by a cartridge. Among the main parts, the cartridge case 3 and the lower spherical bearing 4 can be replaced. The spherical bearing packing 5, the operating body 6, the ball plunger 7, the movable valve body 9, the coupling flange 10, the fixed valve body 11, the watertight communication packing 12, and the O-ring 13 are attached parts. At the same time, it is unitized as a replacement cartridge, and can be sold separately as an assembled maintenance unit.

The main components and the parts attached to the main components will be described below.
The hot / cold mixing tap main body case 1 is a part of the hot / cold mixing tap main body, and is vertically attached to an attachment location such as a washstand on the bottom surface. The hot and cold water mixing plug main body case 1 has a water inflow portion 1a and a hot water inflow portion 1b on the bottom side, a discharge portion 1c which is a discharge port on the side surface, and a screw portion 1d to which the cartridge holder 2 is screwed. A ring-shaped recess 1e through which water / hot water mixed water / hot water can flow into the discharge part 1c is provided.
The cartridge holder 2 is a part for attaching the replacement cartridge to the hot and cold water mixing plug main body case 1 in a lump, and includes a screw portion 2a for screwing attachment.
The cartridge case 3 is a case portion of a replacement cartridge, and includes an upper upright portion 3a and a lower cylindrical portion 3b.
The upper upright portion 3a is provided with a conical tapered portion 3c, a hemispherical concave portion 3d, an arc-shaped cutout portion 3e, an upper spherical bearing portion 3i, a packing mounting portion 3j, and an O-ring mounting portion 3k. Yes.
The conical taper portion 3c is provided at the upper part of the inner side surface of the upper upright portion 3a. The range in which the side surface 6f on the opening direction side (the side surface serving as the advance surface during the opening operation) faces is the opening-side facing portion. The portion of the closed facing portion where the steel ball 7a of the protruding ball plunger 7 abuts is maintained by keeping the vertical rotation angle of the operating body 6 constant when the protruding steel ball 7a abuts. It becomes a water-saving mode closed side facing portion that secures a predetermined amount of water-saving mode lower limit discharge amount.
However, even if the vertical rotation angle of the operating body 6 is constant, the hot water adjustment notch valve port 9b of the movable valve body 9 is horizontally rotated across the water inlet valve port 1a and the hot water inlet valve port 1b. Since the change in the opening area of the valve port is unavoidable, the discharge amount cannot be made strictly constant over the horizontal rotation range.

  In the description of the configuration of the hot and cold water mixing tap of the present embodiment, the markings and changes in the shape of the parts necessary for easy and reliable assembly during production or maintenance are described for the sake of simplifying the description. Not.

The following describes how to use this hot and cold water mixing tap.
(1) Fully closed state before start of use As shown in FIG. 2-1, the horizontal rotation position of the single lever 8 is the rightmost horizontal rotation that discharges only water when the movable valve body 9 moves forward and backward. The position is H1.
Moreover, as shown to FIGS. 1-1, an up-down rotation position is a lower end position used as a fully closed position. In this state, since the steel ball 7a of the ball plunger 7 is recessed into the hemispherical recess 3d of the cartridge case 3, the reaction force of the ball plunger 7 does not act, and even if the hand is released after the fully closed operation. The single lever 8 is not pivoted upward and maintains the fully closed state. At this time, the movable valve body 9 closes the water inflow valve port 11a and the hot water inflow valve port 11b of the fixed valve body 11 as shown in FIG. 2-1.
(2) Water-only discharge operation
From the fully closed state shown in (1), if the single lever 8 is turned upward without the horizontal turning operation, the hot water adjustment notch valve of the movable valve body 9 as shown in FIG. The port 9b does not communicate with the hot water inflow valve port 11b of the fixed valve body 11, but communicates with the water inflow valve port 11a and is fully opened. Therefore, the up / down rotation operation at the horizontal rotation position H1 is the adjustment of the discharge amount of only water, and there is no need to unintentionally waste hot water. FIG. 2-2 shows the positional relationship between the movable valve body 9 and the fixed valve body 11 in the fully opened state at the horizontal rotation position H1.
(3) Water-saving mode operation
From the fully closed state shown in (1), if the single lever 8 is rotated horizontally without rotating up and down, the steel ball 7a of the ball plunger 7 is hemispherical as shown in FIG. The single lever 8 is pivoted upward by the reaction force of the ball plunger 7 so that the single lever 8 is pivoted upward by the reaction force of the ball plunger 7 and the lower limit discharge amount of water / hot water mixed water / Hot water is discharged.
If the horizontal rotation position where the steel ball 7a leaves the hemispherical recess 3d and the mode is switched is the horizontal rotation position H4 shown in FIG. 4A, water saving is achieved on the clockwise side of the horizontal rotation position H4. The mode becomes possible. In this embodiment, since the hemispherical recess 3d is provided only in a part of the horizontal rotation range for discharging only water, the water-saving mode is possible in other horizontal rotation ranges for discharging only water.
That is, as shown in FIG. 1-2, the ball plunger 7 which is a contact portion of the conical taper portion 3c of the cartridge case 3 which is the closed-side facing portion for water saving mode and the closed-side contact portion which moves forward and backward by elasticity. , The vertical rotation angle of the operating body 6 is kept constant, and as shown in FIGS. 4A and 2B, the hot water adjustment notch valve port 9b of the movable valve body 9 is maintained. Is slightly communicated with the water inlet valve port 11a and / or the hot water inlet valve port 11b of the fixed valve body 11, and the position of the movable valve body 9 that discharges a predetermined amount of substantially the same lower limit discharge amount for water-saving mode is maintained. .
In the horizontal rotation range in which the water-saving mode is possible, the single lever 8 can be fully closed if it is rotated downward and held at the lower end position, and the water plunger can save water by releasing the hand and releasing the holding. Returning to the mode, a predetermined amount of water / hot water mixed water / hot water of the lower limit discharge amount for water-saving mode is automatically discharged. When a larger flow rate than the lower limit discharge amount for water saving mode is required, the single lever 8 is rotated upward to adjust the flow rate.
FIG. 4A shows the positional relationship between the movable valve body 9 and the fixed valve body 11 in the water-saving mode when only water is discharged at the horizontal rotation position H4.
FIG. 4B shows the positional relationship between the movable valve body 9 and the fixed valve body 11 in the water-saving mode at the horizontal rotation position H2 where the hot / cold water mixing ratio is equal.
(4) Adjustment of hot water / water mixing ratio / discharge amount As with a conventional single lever type hot / cold water mixing tap, the horizontal movement of the single lever 8 adjusts the hot water / water mixing ratio, and the discharge amount is adjusted by rotating up / down.
FIG. 3A shows the positional relationship between the movable valve body 9 and the fixed valve body 11 in the fully closed state at the horizontal rotation position H2 where the hot / cold water mixing ratio is equal. This state is a state in which the single lever 8 is rotated downward and is held at the lower end position. When the release is released by releasing the hand, the water-saving mode shown in FIG.
FIG. 3-2 shows the positional relationship between the movable valve body 9 and the fixed valve body 11 in the fully opened state at the horizontal rotation position H2. In this state, the vertical pivot position of the single lever 8 is at the upper end, which is the fully open position, and the steel ball 7a of the ball plunger 7 is away from the conical tapered portion 3c of the cartridge case 3, so the ball plunger 7 The reaction force of does not work.
(5) Fully-closed operation after use In order to hold the hot and cold mixing tap in the fully-closed state, a conscious operation is required to return the horizontal / vertical rotation position of the single lever 8 to the state shown in (1). is there.

A modification of this embodiment will be described below.
(1) In business hot water mixing taps and hot water mixing taps for bathtubs, the hemispherical concave portion having the same shape as the hemispherical concave portion 3d is used as a closed-side facing portion that can be fully closed, and the conical tapered portion 3c of the cartridge case 3 is closed facing If it is additionally provided at the position of the hot and cold water mixing ratio of the part, it can be fully closed at this hot water and water mixing ratio, so there is no need to return to the horizontal rotation position H1, and the lever operation is simplified.
(2) If the convex part or the recessed part for generating the click feeling by the steel ball 7a of the ball plunger 7 is suitably provided in the range which becomes the closed side opposing part of the conical taper part 3c, the standard of hot water mixing ratio It can be made easy to attach.
(3) Single at the boundary between the horizontal rotation position for discharging only hot water in the range facing the closed side of the conical taper portion 3c or the high-temperature hot / cold mixed water and the horizontal rotation position for discharging the medium-temperature hot / water mixed water. If the convex part for high temperature warning that cannot get over to the horizontal rotation position side that discharges only hot water or hot hot water mixed water unless the lever is consciously operated, only hot water or hot mixed water is discharged to the user. Since the horizontal rotation position is made clearer, it is possible to avoid the danger of unexpectedly discharging hot water or hot mixed water during use.
(4) Instead of the ball plunger 7, the closed contact portion that moves forward and backward by elasticity may be a roller plunger, and a hemispherical convex portion is formed on the movable side end portion so as to exceed the stroke of the ball plunger 7. A plate spring having a bending amount may be provided on the side surface 6e of the operating body 6 on the closing direction side.
(5) Instead of the ball plunger 7, the closed contact portion that does not move forward or backward due to elasticity may be replaced with a ball roller, a roller, or a simple hemispherical convex portion. In this case, the hemispherical concave portion 3d It can be fully closed only at the provided horizontal rotation position H1.

In the present embodiment, the notch range of the arcuate notch 3e of the cartridge case 3 is changed so that it can be rotated horizontally counterclockwise from the horizontal rotation position H1, and the conical taper of the expanded horizontal rotation range. The portion 3c is changed stepwise in the counterclockwise direction, and the adjustment of the water-saving mode lower limit discharge amount to be increased stepwise when it is horizontally turned counterclockwise from the horizontal turning position H1 is eliminated. It is not a thing.
However, the conical tapered portion in this range is a tapered surface that does not generate a component force in the horizontal rotation direction with respect to the steel ball 7a of the ball plunger 7.

The water stop regulating member of the above-mentioned Patent Document 11 and the water-saving mode close-side facing portion of the present invention are different in the following points.
(1) Whereas the function of the water stop regulating member is only to prevent the full closing operation on the high temperature side, the function of the water-saving mode close-side facing portion is at least one of the ranges in which water or hot water mixed water is discharged. This is a function of discharging a predetermined amount of the lower limit discharge amount for water-saving mode that is useful in the section.
(2) The setting range for restricting the vertical rotation of the water stop regulating member is wide as long as it is simply in the opening direction from the position for preventing the full closure. The setting range for restricting the pressure has a condition for discharging a useful predetermined amount of the lower limit discharge amount for water-saving mode, and the setting range is limited.
(3) Whereas the horizontal rotation range in which the water stop regulating member is provided is limited to the high temperature side, the water-saving mode close-side facing portion is a part of the horizontal rotation range in which water or hot water mixed water is discharged. Therefore, the horizontal rotation range provided is different.
In the present embodiment, the water-saving mode closed-side facing portion is supplied with water between the horizontal rotation position H4 for discharging only water, the water between the horizontal rotation position H4 and the horizontal rotation position H2, or the mixed water of low / medium temperature. The horizontal rotation range for discharging, the horizontal rotation range for discharging hot / cold hot water / water mixture or hot water between the horizontal rotation position H2 and the horizontal rotation position H3, and the horizontal rotation position H3 for discharging only hot water. Have.
(4) Whereas the water stop regulating member is provided at the upper part of the mixing plug main body, the water-saving mode close-side facing portion is not limited to the upper part of the mixing plug main body shown in the first to third embodiments. As shown in 4, 5 and 6, it can also be provided inside the mixing plug body.
(5) In addition to the effect of preventing unintentional discharge of high-temperature hot water in the water stop regulating member, it is possible to prevent unintentional waste of hot water at the start of use by providing the water-saving mode closed facing portion. There is no effect.

The engaging member disclosed in Patent Document 12 is different from the water-saving mode closed-side facing portion of the present invention in the following points.
(1) The function of the engaging member is to prevent the full-closed operation only by suppressing the opening / closing operation of the single lever in the middle, whereas the water-saving mode close-side facing part prevents the full-closed operation. At the same time, it has a function to discharge the lower limit discharge amount for water saving mode.
(2) While the engaging member can be left in the fully closed state of the single lever, the water-saving mode close-side facing portion is single even if a closed-side abutting portion that moves forward and backward by elasticity is provided. It is impossible to leave the lever in the fully closed state.
(3) Whereas the engaging member is provided over the horizontal rotation range, the water-saving mode closed-side facing portion is not provided in the entire horizontal rotation range.
(4) In addition to the effect of preventing water hammer phenomenon and splashing of hot water, the engaging member has an effect of preventing unintentional waste of hot water at the start of use by providing a water-saving mode close-side facing portion. There is no.

The range where the steel ball 7a of the ball plunger 7 in the protruding state contacts the closed side facing portion for the water saving mode. However, when the steel ball 7a is pushed into the case of the ball plunger 7, it can be temporarily fully closed.
The hemispherical concave portion 19b is a fully-closable close side facing portion into which the steel ball 7a of the ball plunger 7 is depressed, and is provided on the upper surface of the conical tapered portion 19b in terms of shape. Therefore, at the position of the hemispherical recess 19b, the single lever 8 is not rotated in the opening direction by the reaction force of the ball plunger 7, and the fully closed position is maintained. The shape of the hemispherical recess 19b is set to a size that does not interfere with the ball plunger 7 when the adjustment bolt 18 is adjusted.
Other configurations are the same as those of the first embodiment.

The following describes how to use this hot and cold water mixing tap.
(1) Fully closed state before start of use In advance, the cap 19 is fixed to the hot and cold water mixing tap main case 1 with the position of the hemispherical recess 19b set to the horizontal rotation position H1, and the ball plunger 7 is The projecting length is adjusted by the adjusting bolt 18 so that the lower limit discharge amount for the water-saving mode becomes a predetermined amount when the steel ball 7a comes into contact with the conical tapered portion 19a of the cap 19.
The horizontal rotation position of the single lever 8 is the rightmost horizontal rotation position H1 as shown in FIG. 2-1, and the vertical rotation position is the lower end position that is the fully closed position as shown in FIG. 5-1. It is. FIG. 5A is a vertical cross-sectional view at the horizontal rotation position H1. In this figure, the steel ball 7 a of the ball plunger 7 is not in contact with both the conical tapered portion 19 a and the hemispherical concave portion 19 b, but the side surface 9 c on the closing direction side of the movable valve body 9 is the lower cylinder of the cartridge case 3. It contacts the inner surface 3g of the shaped portion 3b.
(2) Water-only discharge operation As in the first embodiment, if the single lever 8 is not horizontally rotated from the fully closed state shown in (1), but is turned up and down, the amount of water only discharged It becomes adjustment and does not waste water unconsciously.
(3) Water-saving mode operation
From the fully closed state shown in the item (1), if the horizontal rotation operation is performed in the clockwise direction without the up / down rotation operation of the single lever 8, the horizontal rotation position H4 shown in FIG. As shown, the steel ball 7a of the ball plunger 7 leaves the hemispherical recess 19b and contacts the conical tapered portion 19a, so that the single lever 8 is rotated upward by the reaction force of the ball plunger 7, and a predetermined amount of Water of the lower limit discharge amount for water saving mode is discharged.
A water-saving mode is possible on the clockwise side of the horizontal rotation position H4 at which the steel ball 7a leaves the hemispherical recess 19b of the cap 19. Also in this embodiment, since the hemispherical recess 19b is provided only in a part of the horizontal rotation range for discharging only water, the water saving mode is possible in other horizontal rotation ranges for discharging only water.
That is, as shown in FIG. 5B, the conical tapered portion 19a of the cap 19 that is the closing side facing portion and the ball plunger 7 that is the contact portion of the closing side contact portion that moves forward and backward by elasticity are in a protruding state. When the steel ball 7a abuts, the vertical rotation angle of the operating body 6 is kept constant, and the hot water adjustment notch valve port 9b of the movable valve body 9 is fixed to the fixed valve body as shown in FIGS.

The plunger holder 23 is screwed and attached to a screw portion 1h for screwing attachment of the cylindrical portion 1g of the hot and cold mixing plug main body case 1 together with a watertight O-ring 24.
In the movable valve body 9, a contact portion 9e that contacts the steel ball 7a of the ball plunger 7 on the side surface 9c on the closing direction side is used as a closing side contact portion. Of the contact part 9e, the part closest to the closing direction also contacts the inner side surface 3g of the lower cylindrical portion 3b of the cartridge case 3.
Further, on the side surface 9c on the closing direction side, a hemisphere for avoiding interference with the steel ball 7a of the ball plunger 7 when the movable valve element 9 is in the fully closed position at the horizontal rotation position H1.

The arc-shaped thick portion 14a is located at the position of the lower limit discharge amount for the water-saving mode when the fully closed movable valve body 9 is horizontally rotated clockwise at the rightmost horizontal rotation position H1. While retreating, the lower limit discharge amount for the water-saving mode is secured when the contact portion 9e of the movable valve body 9 is in contact with the portion closest to the closing direction.
The arcuate thin-walled portion 14b is a fully-closeable close-side facing portion in a range where the most closed direction portion of the contact portion 9e of the movable valve element 9 can be contacted. Only H1 becomes a fully-closeable close side facing portion.
The side surface opening 14 c communicates with the side surface opening 3 f of the cartridge case 3 and is an opening through which water / hot water / mixed water / hot water flows out to the ring-shaped recess 1 e of the hot / cold water mixing case 1.
The fixed valve body 11 and the watertight communication packing 12 are the same as those of the first embodiment except for the change in the relational dimensions due to the new mounting of the cylindrical adapter 14.

Further, the cutout portion of the arcuate cutout portion 3e that restricts the horizontal rotation range of the single lever 8 is also changed so that the horizontal rotation range of the single lever 8 is in the range of H3 to HR1.
The other components are the same as those in the first embodiment.

The following describes how to use this hot and cold water mixing tap.
(1) Fully closed state before start of use As shown in FIG. 16-1, the horizontal rotation position of the single lever 8 is the horizontal rotation position H1 which is the front of the hot and cold water mixing tap, and the vertical rotation position is As in Example 1, the lower end position is the fully closed position.
(2) Discharge operation of tap water only The same as in the first embodiment.
16-1 shows the positional relationship between the fully-closed movable valve element 9 and the fixed valve element 11 at the horizontal rotation position H1, and FIG. 16-2 shows the positions of the fully-opened movable valve element 9 and the fixed valve element 11. Show the relationship.
(3) Water-saving mode operation When not using the tap water-compatible water purifier 29, as in the first embodiment, if the single lever 8 is not rotated up and down and is rotated horizontally in the clockwise direction, the horizontal rotation is performed. At a position in the clockwise direction from the position H4, a predetermined amount of water / hot water mixed water / hot water of a lower limit discharge amount for water saving mode is discharged.
(4) Adjustment of hot / cold water mixing ratio / discharge amount The same as in the first embodiment.
(5) Discharge of clean water and adjustment of discharge amount As shown in FIG. 17-1, the horizontal rotation position of the single lever 8 is horizontally rotated counterclockwise so that the horizontal rotation position HR1 is the rightmost end. After the horizontal rotation, the discharge amount is adjusted by rotating up and down. At the horizontal rotation position HR1, tap water becomes purified water through the path of the second water supply system 36 branched from the first water supply system 34 and the tap water purifier 29, and the third inflow path 32 and the hot water adjustment notch of the movable valve body 9 are provided. It is discharged through the route of the valve port 9b, the side opening 3f of the cartridge case 3, the ring-shaped recess 1e of the hot and cold water mixing plug body case 1, and the discharge part 1c.
Since the horizontal rotation position HR4 is a position for switching to the water saving mode similarly to the horizontal rotation position H4, the single lever 8 is fully closed by hand in the range of the horizontal rotation position HR4 to the horizontal rotation position HR1. If it is not held in the up / down rotation position, it cannot be fully closed.
During the horizontal rotation, the hot water adjustment notch valve port 9b of the movable valve body 9 allows the water inlet valve port 11a and the third inlet valve port 11c of the fixed valve body 11 to communicate with each other at the same time. Even if tap water and purified water flow into the water at the same time, the purified water flowing out from the third inlet valve port 11c due to the pipe resistance by the tap water compatible water purification device 29 etc. is a short amount of discharge, and the tap water compatible purified water The life of the device 29 is hardly affected.
FIG. 17-1 shows the positional relationship between the fully closed movable valve element 9 and the fixed valve element 11 at the horizontal rotation position HR1, and FIG. 17-2 shows the positions of the fully opened movable valve element 9 and the fixed valve element 11. Show the relationship.
(6) Fully-closed operation after use In the same manner as in Example 1, in order to keep the hot and cold mixing tap in the fully-closed state, the consciousness of returning the horizontal / vertical rotation position of the single lever 8 to the state shown in the item (1) Operation is necessary.

If a solar water heater is connected instead of the water purifier 29 for tap water, the second water supply system 36 becomes the second hot water supply system, and the third inflow path 32 becomes the solar hot water inflow path. The mixing tap becomes a hot water mixing tap combined with a solar water heater.
Similarly, if a commercially available beverage container such as mineral water is separated from the first water supply system 34 and connected to the third inflow path 32, a beverage container combined hot and cold water mixing tap is obtained.
However, in these cases, the hot and cold water mixing plug main body is such that the water pressure of the first water supply system 34 is not applied to the solar water heater or the beverage container via the water inflow path 30 and the third inflow path 32. It is better to provide a check valve outside the third inflow portion 1i of the case 1. Alternatively, the water inlet valve port 11a and the third inlet valve port 11c of the fixed valve body 11 are spaced so that the hot water adjustment notch valve port 9b of the movable valve body 9 does not communicate with each other during horizontal rotation. May be.

In the first embodiment, the water / hot water mixed water / hot water flowing into the hot water adjustment cutout valve port 9 b of the movable valve body 9 passes through the space above the fixed valve body 11 and the side opening 3 f of the cartridge case 3. In contrast to flowing into the ring-shaped recess 1e of the hot and cold water mixing plug body case 1,
In this embodiment, the water / hot water mixed water / hot water flowing into the hot water adjusting recess valve port 9h of the movable valve body 9 is discharged into the discharge valve port 11d of the fixed valve body 11, the space above the fixed valve body 11, and the cartridge case 3. The discharge path flows into the ring-shaped recess 1e of the hot and cold water mixing plug main body case 1 through the side opening 3f.
The second discharge path 38 is a path for discharging the water / hot water mixed water flowing into the hot water adjusting recess valve port 9h of the movable valve body 9 to the intermediate temperature corresponding water purification device 41, and the second discharge valve of the fixed valve body 11 is used. The outlet 11e, the second discharge port 12d of the watertight communication packing 12, and the second discharge portion 1j of the hot and cold water mixing plug main body case 1 are connected via the adjustment / replacement valve 33 and the intermediate temperature water purifier 41. , Connected to the purified water discharge path 39.

Inserted with the replacement valve 33.
In the cartridge case 3, the position of the hemispherical concave portion 3 d that becomes the fully-closeable close side facing portion is changed to the front side position so as to correspond to the horizontal rotation position H 1. Therefore, there is an effect that the medium temperature-compatible water purifier 41 is used unconsciously at the start of use, and the life of the medium temperature-compatible water purifier 41 is not shortened. Further, the cutout portion of the arcuate cutout portion 3e that regulates the horizontal rotation range of the single lever 8 is also changed so that the horizontal rotation range of the single lever 8 is in the range of H3 to HR3.
The other components are the same as those in the first embodiment.

The following describes how to use this hot and cold water mixing tap.
(1) Fully closed state before start of use As shown in FIG. 19-1, the horizontal rotation position of the single lever 8 is the horizontal rotation position H1 on the front side of the hot-water mixing tap, and the vertical rotation position is As in Example 1, the lower end position is the fully closed position. Leave in the fully closed state is limited to the horizontal rotation position H1.
In FIG. 19A, a two-dot chain line indicates the position of the hot water adjusting recess valve port 9h of the movable valve body 9 in the fully closed state (held by hand) at the leftmost horizontal rotation position H3 that discharges only hot water. Show.
(2) Discharge operation using only water The same operation as in the first embodiment.
FIG. 19-2 shows the positional relationship between the movable valve body 9 and the fixed valve body 11 in the fully opened state at the horizontal rotation position H1. In the drawing, a two-dot chain line indicates the position of the hot water adjusting concave portion 9h of the movable valve body 9 in the fully opened state at the horizontal rotation position H3.
(3) Water-saving mode operation When the intermediate-temperature water purifier 41 is not used, as in the first embodiment, if the horizontal rotation operation is performed clockwise without performing the vertical rotation operation of the single lever 8, the horizontal rotation position At a position in the clockwise direction from H4, a predetermined amount of water / hot water mixed water / hot water of a lower limit discharge amount for water saving mode is discharged.
(4) Adjustment of hot / cold water mixing ratio / discharge amount The same as in the first embodiment.
(5) Purified water discharge and adjustment of discharge amount When discharging purified water of tap water, as shown in FIG. 20-1, the horizontal rotation position of the single lever 8 is set to the horizontal rotation position HR1. After turning horizontally in the clockwise direction, it is turned up and down to adjust the discharge amount. In the present embodiment, the range in the counterclockwise direction from the horizontal rotation position HR4 is the water saving mode range.
At the horizontal rotation position HR1, water is purified water through the first water supply system 34, the water inflow path 30, the hot water regulating recess valve port 9h, the second discharge path 38, the intermediate temperature-compatible water purifier 41, and the purified water discharge path 39. And discharged from the discharge portion 1c.
Even during horizontal rotation, the hot water adjustment recessed valve port 9h of the movable valve body 9 communicates the water inlet valve port 11a of the fixed valve body 11 with the first discharge valve port 11d and the second discharge valve port 11e. The discharge amount of the water (raw water) flowing out from the second discharge valve port 11e due to the pipe resistance of the intermediate temperature corresponding water purification device 41 or the like is a small amount in a short time, and hardly affects the life of the intermediate temperature corresponding water purification device 41.
When changing the mixing ratio of the raw water and hot water, it rotates horizontally further counterclockwise than the horizontal rotation position HR1. The horizontal rotation position HR2 is the horizontal rotation position of the uniform mixed water raw water, and the horizontal rotation position HR3 is the rightmost horizontal rotation position of the mixed water raw water. In the present embodiment, by preventing only hot water from flowing into the intermediate temperature purifier 41, no thermal failure occurs in the intermediate temperature purifier 41.

In this figure, the two-dot chain line indicates the position of the hot water adjusting concave portion 9h of the movable valve body 9 in the fully opened state at the horizontal rotation position HR3.
6) Fully-closed operation after use In the same way as in Example 1, in order to hold the hot and cold mixing tap in the fully-closed state, the horizontal / vertical rotation position of the single lever 8 is consciously returned to the state shown in (1). Operation is necessary.

It is also possible to connect the water purifying device 41 for medium temperature to the purified water discharge path 39 of the hot / cold water mixing tap, and connect it directly to the discharging device for purified water separately from the hot water / water mixing tap.
If a shower head is connected in place of the medium temperature water purifier 41, it becomes a safe shower head combined hot and cold water mixing tap that does not always discharge hot water, not only at the start of use. In this case, the adjustment / replacement valve 33 and the purified water discharge path 39 are unnecessary.
The method of use in this case is the same as in this embodiment.
