And “the same cylindrical body” refers to “the same cylindrical body including the through-hole”, and “highly identical cylindrical body” means “the difference in the formation mode of the through-hole (shape, “The same cylindrical body” except for the difference in size).

  That is, in the “first mode”, both of the two types of through-holes (any type of through-holes may be one or a plurality) are used.

Only the configuration of the through holes provided in the temperature adjusting fixed valve body and the switching fixed valve body is different between the valve body and the switching movable valve body). For this reason, the commonality of a component is improved between the temperature control valve device and the switching valve device.

And the 2nd extraction flow path is comprised with the other kind of through-hole.

  Further, in the “third aspect”, two cylindrical bodies each having one kind of through-hole (whether one or a plurality of through-holes) are provided, and the configuration aspect of the through-holes (A specific example of a cylindrical body having high identity) that differs only (at least the circumferential width is different).

Only the configuration of the through holes provided in the body part is different. For this reason, the commonality of a component is improved between the temperature control valve device and the switching valve device.

  In addition, according to the invention of claim 1, it is possible to obtain an effect that it is possible to satisfy both “a request for lowering the manufacturing cost of a hot and cold water mixing faucet and a request for higher accuracy of temperature control”. That is, in a hot and cold water mixing faucet equipped with a conventional “temperature control valve device” and “switching valve device”, the above-mentioned “thermostat type temperature control valve device” or the so-called “temperature control valve device” can be used. A lift-type temperature control device has been used.

  Here, the “thermostat type temperature control device” is a temperature control valve that adjusts the hot water temperature by adjusting the opening ratio between the hot water supply port and the water supply port using a temperature sensing element that expands and contracts in response to temperature changes. Device.

  Further, as shown in FIG. 30, the “lift-type temperature control device” includes a housing 90, a shaft 91 whose axis is directed in the vertical direction in the housing 90, and a predetermined length along the axial direction of the shaft 91. The hot water valve element 92 and the water valve element 93, which are lined up and down at intervals, are mainly configured. In this temperature control valve device, a hole-shaped hot water valve seat 95 and a hole-shaped water valve seat 96 are provided in the housing 90, and the shaft 91 moves up and down to move the hot water valve. The body 92 is seated on the hot water valve seat 95, or the water valve body 93 is seated on the water valve seat 96. Then, the ratio of the opening degree of the hot water valve seat 95 and the opening degree of the water valve seat 96 is selected according to the amount of movement of the shaft 91 in the vertical direction, whereby the secondary side of the housing 90 is selected. The temperature of hot water flowing out (outside) is adjusted.

  These temperature control devices have the following problems. That is, the “thermostat type temperature control device” has a complicated structure mainly composed of the “temperature sensing element”, so that the manufacturing cost tends to be high.

  On the other hand, the lift-type temperature control device has a simple structure as compared with the “thermostat-type temperature control device”, and therefore the manufacturing cost can be reduced. However, for the following reasons, the sealing portion (the part to be seated with respect to the hot water valve seat 95 and the water valve seat 96 in the hot water valve body 92 and the water valve body 93). In addition, since an “elastic seal member such as rubber” cannot be used, it is difficult to perform temperature adjustment with high accuracy.

  As shown in FIGS. 31 (a) and 31 (b), a circumferential groove 97 that is recessed in the axial direction of the shaft 91 is provided on the outer periphery of the valve bodies 92 and 93, and an "O-ring (rubber) is formed in the circumferential groove 97. And the like, the following problem occurs. That is, when the valve bodies 92 and 93 are seated on the valve seats 95 and 96 in an insertion manner, the elastic member 98 is deformed to reduce its radius, as shown in FIG. When the valve bodies 92 and 93 are removed from the valve seats 95 and 96, the elastic member 98 is deformed to restore its radius, as shown in FIG. 31 (b). When the valve bodies 92 and 93 are seated on the valve seats 95 and 96 and the valve bodies 92 and 93 are separated from the valve seats 95 and 96, the elasticity of the elastic member 98 is gradually reduced. The watertightness between the bodies 92 and 93 and the valve seats 95 and 96 gradually decreases. Further, when the elastic member 98 that is seated on the valve seats 95 and 96 and is in a compressed state is removed from the valve seats 95 and 96, the radius thereof may be increased more than necessary. In this case, when the valve bodies 92 and 93 are seated again on the valve seats 95 and 96, the peripheral portion of the elastic member 98 may be caught on the inlet portions 95 a and 96 a of the valve seats 95 and 96.

  Therefore, in the lift-type temperature control device, it is general that the hot water valve body 92 and the water valve body 93 are made of only a highly rigid material (metal). Since the valve seats 95 and 96 are usually made of metal (cast), in the lift type temperature control device, the metal valve body 92 and the valve body 93 are seated on the metal valve seats 95 and 96. A structure to be adopted is adopted. For this reason, usually, a predetermined clearance is provided between the outer diameter of the valve bodies 92 and 93 and the inner diameter of the valve seats 95 and 96, so that the valve bodies 92 and 93 can be smoothly moved with respect to the valve seats 95 and 96. It is performed to be able to be inserted into.

  Therefore, in the lift-type temperature control device, an inevitable gap (clearance) exists between the valve bodies 92 and 93 and the inner wall portions of the valve seats 95 and 96. For this reason, as described above, according to the lift-type temperature control device, it is difficult to perform temperature adjustment with high accuracy.

  Due to the above circumstances, in a hot and cold water mixing faucet equipped with a “temperature control valve device” and a “switching valve device”, a request for lowering the manufacturing cost of the hot water and water mixing faucet and higher accuracy of temperature control are required. It is anxious to balance “request”.

  On the other hand, in the invention of claim 1, the temperature adjusting valve device has a simple configuration mainly composed of a temperature adjusting fixed valve body portion and a temperature adjusting movable valve body portion. It can be manufactured at a low cost as in the case of the "temperature control device". According to the first aspect of the present invention, a temperature control valve capable of performing high-precision temperature control by applying "improvement against normal technical common sense" to the slide valve device (rotary slide valve). Trying to get the device. That is, the sliding valve device has high water tightness and exhibits a complete water stop function (function of completely blocking the primary side flow path of the valve device and the secondary side flow path of the valve device). It is valid. However, in the invention of claim 1, the sliding valve device is improved and is always connected to the continuous water type (a type in which the flow path on the primary side of the valve device and the flow path on the secondary side of the valve device are always in communication). ) Is used as a temperature control valve device. In the first aspect of the invention, the temperature adjustment is performed using the sliding valve having a high water tightness as described above, so that the temperature can be adjusted with high accuracy.

  The “temperature control communication channel” of the invention of each claim may be constituted by a single through-hole provided at a predetermined position of the temperature control movable valve body portion. You may be comprised by the some through-hole provided in the location. In addition, the “temperature control communication channel” of the invention of each claim includes a communication channel unit dedicated to the “hot water inflow channel” and a communication channel unit dedicated to the “water supply inflow channel”. It may be configured. That is, the “temperature control communication channel” of the invention of each claim is communicated with or not communicated with the “hot water supply inflow channel” in accordance with the rotation of the temperature control movable valve body (A). However, the “water supply inflow channel” always communicates with the “water supply inflow channel” according to the rotation of the non-communication communication channel portion and (B) the temperature control movable valve body. However, the “inflow channel for hot water supply” may always be constituted by a non-communication communication channel part.

  Similarly, the “switching communication channel” of the invention of each claim may be constituted by a single through-hole provided at a predetermined position of the switching movable valve body portion. You may be comprised by the several through-hole provided in the multiple places of a part. In addition, the “switching communication channel” of the invention of each claim includes a communication channel unit dedicated to the “first extraction channel”, and a communication channel unit dedicated to the “second extraction channel”. , May be configured. That is, the “switching communication channel” of the invention of each claim is communicated with (a) the “first extraction channel” or non-communication according to the rotation of the switching movable valve body. However, the “second extraction flow path” is always “non-communication communication flow path section” and (B) “second extraction flow path” according to the rotation of the switching movable valve body section. However, the “first extraction flow channel” may be configured by a non-communication communication channel portion at all times.

The hot and cold water mixing faucet of the invention of claim 2 is the hot water and water mixing tap of claim 1,
When the temperature control movable valve body is rotated within the range of the first rotation angle,
The temperature control communication channel communicates with the hot water inflow channel and is not in communication with the water supply inflow channel;
The temperature control communication channel is in communication with the hot water inflow channel and the water supply inflow channel;
The temperature control communication channel is not in communication with the hot water inflow channel, and is in a state of being in communication with the water supply inflow channel.

  According to the invention of claim 2, it is possible to obtain a hot and cold water mixing faucet that is more convenient to use. In other words, in the above-mentioned “lift-type temperature control valve device”, (1) hot water supplied to the temperature control valve device from a hot water supply source (such as a hot water heater) (hereinafter sometimes referred to as “moto hot water”), In that state (the water supplied to the temperature control valve device is not mixed), it may be discharged out of the temperature control valve device (hereinafter referred to as “original hot water supply” or “one-side hot water supply”). ) Is difficult, and (2) the water supplied to the temperature control valve device from the water supply source (water supply piping, etc.) (hereinafter sometimes referred to as “source water”) is left in its state (temperature control valve). It is difficult to discharge the hot water supplied to the apparatus out of the temperature control valve apparatus (hereinafter sometimes referred to as “original water supply” or “one-side water supply”). And the usability is getting worse.

  That is, as shown in FIGS. 30 and 31, in the lift-type temperature control valve device, as described above, an unavoidable gap is formed between the valve bodies 92 and 93 and the inner wall portions of the valve seats 95 and 96. (Clearance) exists. For this reason, even if it is going to perform "original hot water supply", the water which passes through the clearance gap (clearance) between the valve body 93 for water and the valve seat 96 for water mixes in the original hot water. Similarly, even when trying to execute “original water supply”, hot water passing through a gap (clearance) between the hot water valve element 92 and the hot water valve seat 95 is mixed into the raw water. For this reason, it is difficult to perform “form water supply” or “form water supply” with a lift-type temperature control valve device.

  In recent years, the performance of the “hot water heater” that constitutes the hot water supply source of the hot and cold water mixing faucet has been remarkably improved, and the temperature control of the hot water flowing out from the “hot water heater” can be performed with high accuracy. However, if a lift-type temperature control valve device is used, the improvement in performance of the “water heater” cannot be fully utilized. For example, even though hot water of “40 degrees Celsius” is supplied from a “hot water heater” with high accuracy, the temperature of the hot water discharged from the hot water mixing faucet (temperature control valve device) is “37 degrees Celsius”. This is because there may be a problem that it is lowered. Therefore, in order to make use of “improvement of the performance of the water heater”, it is desirable to make an appropriate improvement to the temperature control valve device.

  On the other hand, according to the invention of claim 2, by selecting the rotation position (rotation angle) of the temperature adjustment movable valve element (temperature adjustment movable valve element), (1) the temperature adjustment communication channel In communication with the inflow channel for hot water supply, the temperature control communication channel in a state of non-communication with the inflow channel for water supply, and (2) the temperature control communication channel in communication with the inflow channel for water supply, It is possible to realize a state in which the temperature control communication channel is not in communication with the hot water inflow channel. For this reason, according to the invention of claim 2, “original hot water supply” and “original water supply” can be suitably performed. Therefore, according to the invention of claim 2, it is possible to obtain a temperature control valve device that is more convenient to use.

The hot and cold water mixing faucet according to claim 3 is the hot water and water mixing faucet according to claim 1 or claim 2,

  The invention of claim 3 exemplifies a specific mode of the temperature regulating valve device.

Each sealing member that is covered and attached to the temperature regulating fixed valve body may exhibit a “behavior to move away from the temperature regulating fixed valve body and enter the temperature regulating communication channel”. However, this behavior can be prevented or suppressed by the portion located between the plurality of communication holes in the temperature control movable valve body.

  In the third aspect of the invention, the temperature control communication channel includes a communication channel dedicated to the “hot water inflow channel” and a communication channel dedicated to the “water supply inflow channel”. Also good. In other words, the communication channel can communicate with the inflow channel for hot water supply, but can communicate with the inflow channel for hot water and the inflow channel for water supply that cannot communicate with the inflow channel for water supply. However, a water-side communication channel that cannot communicate with the inflow channel for hot water supply may be provided. In this aspect, for example, an “inlet flow channel for hot water supply” and an “inflow channel for water supply” are provided at a predetermined interval along the axial direction of the temperature control movable valve body, and hot water is supplied. The side communication channel and the water side communication channel are provided at predetermined intervals along the axial direction of the movable valve body, and the "water supply inflow channel" and the hot water side communication channel are provided. Realized by enabling positioning of the temperature control movable valve body in the radial direction and enabling the "water supply inflow channel" and the water-side communication channel to be aligned in the radial direction of the temperature control movable valve body. it can. Further, it is desirable that the hot water side communication channel and the water side communication channel are also configured by using a plurality of communication holes arranged at predetermined intervals in the axial direction of the movable valve element.

Each sealing member that is covered and attached to the switching fixed valve body portion may exhibit a “behavior to move away from the switching fixed valve body portion and enter the switching communication channel”. However, this behavior can be prevented or suppressed by a portion located between the plurality of communication holes in the switching movable valve body.

  Next, a specific example of the procedure for assembling the temperature control valve device B will be described. First, the rear end side opening 22a of the main body member 21 (the rear end opening of the temperature adjusting fixed valve body 20) and the front end opening 31b of the temperature adjusting movable valve body 30 are concentrically aligned, The temperature control movable valve body 30 is inserted into the main body member 21. This insertion is performed until the flange portion 35 for preventing the temperature adjusting movable valve body 30 from coming off comes into contact with the rear end surface of the main body member 21. As a result, the temperature control movable valve body 30 can be rotated with respect to the main body member 21 inside the main body member 21. In this rotation, the axis of the temperature adjusting movable valve body 30 is aligned with the axis of the main body member 21, and the outer peripheral portion of the temperature adjusting movable valve body 30 is slid to the inner peripheral portion of the main body member 21. Done in state.

  As described above, when the temperature control movable valve body 30 is inserted into the main body member 21, the “two hot water supply side communication holes 32 a and 32 a” on the rear end side of the temperature control movable valve body 30 and the rear of the main body member 21. The end side “hot-water supply side attached hole 23 a” is aligned with the axial direction of the temperature adjusting movable valve body 30. At the same time, the “two water supply side communication holes 32b, 32b” on the front end side of the temperature control movable valve body 30 and the “water supply side mounting hole 23b” on the front end side of the main body member 21 are the temperature control movable valve body. It is aligned in the direction of 30 axial centers.

  The temperature control movable valve body 30 is rotated in one direction of rotation, and the “hot water supply side mounting hole 23a” and the “two hot water supply side communication holes 32a and 32a” circulate around the main body member 21. Align along. Then, when looking into the “hot water supply side attached hole 23 a”, “two hot water supply side communication holes 32 a, 32 a” fit inside the outer edge of the “hot water supply side attached hole 23 a”. Further, the temperature control movable valve body 30 is rotated in the other rotation direction so that the “water supply side mounted hole 23b” and “the two water supply side communication holes 32b and 32b” circulate around the main body member 21. Align along. Then, when looking into the “water supply side attached hole 23b”, the “two hot water supply side communication holes 32b and 32b” fit inside the outer edge of the “water supply side attached hole 23b”.

  After the temperature adjustment movable valve element 30 is inserted into the main body member 21, the front end portion of the temperature adjustment movable valve element 30 exposed from the opening 22 b on the front end side of the main body member 21 is held by the holding portion 41 of the spindle 40. The spindle 40 is integrated with the temperature control movable valve body 30. Thereby, the spindle 40 and the temperature control movable valve body 30 (movable cylindrical part) are connected in series, and the spindle 40 and the temperature control movable valve body 30 can be rotated together. The outer diameter of the holding portion 41 of the spindle 40 is made larger than the outer diameter of the opening 22 b on the front end side of the main body member 21. The main body member 21 is sandwiched at both ends by a flange portion 35 for preventing removal constituting a part of the temperature control movable valve body 30 and a holding portion 41 integrated with the temperature control movable valve body 30. It becomes. For this reason, the main body member 21 and the temperature adjusting movable valve body 30 are prevented from being carelessly detached.

  After the spindle 40 is integrated with the temperature control movable valve body 30, the mounting member 50 and the seal member 55 are mounted in each of the "hot water supply side mounting hole 23a" and the "water supply side mounting hole 23b". To do. This operation is performed by attaching each attachment member 50 to each attachment hole 23a, 23b with the seal member 55 attached to the outer edge portion 52 thereof. Thus, when the temperature control movable valve body 30 is appropriately rotated, the “hot water inflow passage 7H” constituted by the mounting member 50 mounted in the hot water-mounted mounting hole 23a becomes the temperature control movable valve body. The hot water supply side communication holes 32a and 32a (communication flow path 32H) formed in 30 can be opposed (overlapped with each other) in the radial direction of the temperature adjusting movable valve body 30. In addition, when the temperature control movable valve body 30 is appropriately rotated, the “water supply inflow passage 5W” constituted by the mounting member 50 mounted in the mounting hole 23b on the water supply side becomes the temperature control movable valve body 30. The communication holes 32b and 32b (communication flow path 32W) on the hot water supply side formed in the above can be opposed (overlapped) in the radial direction of the temperature control movable valve body 30.

That is, as shown in FIG. 7A, each through-hole 51 has a “substantially turtle-shaped shape in which a pair of apex portions 51 a and 51 b are arranged along the direction of circling the peripheral wall portion 23 of the temperature regulating fixed valve body 20. It is said that. For this reason, in both “movable openings”, both end sides thereof are defined as “width changing portions H1 and H2 in which the width along the axial direction of the temperature adjusting movable valve body 30 changes”. Further, in “the opening of any through hole 51 on the temperature adjusting movable valve body 30 side”, the portion sandwiched between the width changing portions H1 and H2 is the width along the axial direction of the temperature adjusting fixed valve body 20. Is a constant “constant width portion HC”.

  That is, the width along the axial direction of the temperature adjusting movable valve body 30 (movable cylindrical portion) of the “movable side opening” is the temperature adjusting movable valve body 30 (movable cylindrical shape) at one width changing portion H1. Part) is gradually increased (in a linear function) along the direction of circulated. Then, it becomes constant at the end point of the width changing portion H1, and in the “width constant portion HC”, this constant value is maintained along the direction of circulating the temperature adjusting movable valve body 30 (movable cylindrical portion), and then the other side In the width change part H2, it decreases gradually (in a linear function) along the direction which goes around the temperature control movable valve body 30.

  In addition, when the temperature control valve device B is operated and each communication hole 32a (32b) overlaps with the corresponding through hole 51 (51) (when communicating), in each through hole 51 (51), The part that first intersects with the corresponding communication hole 32a (32b), that is, the “communication start end K of the through hole 51 (51)” is the following part. That is, in each through-hole 51 (51), one end portion along the circumferential direction of the temperature regulating fixed valve body 20 becomes the “fixed-side communication start end portion K” (see FIG. 18). In the following description, the “communication start end K of the temperature regulating fixed valve body 20” is referred to as “fixed-side communication start end K”.

  On the other hand, when the temperature control valve device B is operated and each communication hole 32a (32b) overlaps with the corresponding through hole 51 (51), the corresponding communication hole 32a ( The part that finally intersects with 32b), that is, the “valve opening end portion E” is the following part. That is, as shown in FIG. 18 (b), in each through hole 51 (51), the other end portion along the circumferential direction of the temperature regulating fixed valve body 20 becomes this “valve opening terminal portion E”. In the following description, the “communication end portion E of the temperature regulating fixed valve body 20” is referred to as “fixed-side communication end portion E”.

  In the two through holes 51 for configuring the hot water inflow channel 7H, the “fixed-side communication start end portion K” is constituted by one apex portion 51a of the through-hole 51, and the “fixed-side communication” The end portion E ”is constituted by the other apex portion 51 b of the through hole 51. Further, in the two through holes 51 for constituting the inflow channel 5W for water supply, the “fixed-side communication start end portion K” is constituted by the other apex portion 51b of the through-hole 51, and “fixed-side communication” The end portion E ”is constituted by one apex portion 51 a of the through hole 51.

  Further, in this embodiment, “the hot water side communication holes 32a and 32a for configuring the hot water side communication flow path 32H” and “the water supply side communication holes 32b for configuring the water side communication flow path 32W”. , 32b ", the shape of the" opening on the fixed valve body 20 side (hereinafter referred to as "fixed-side opening") "is a special shape. That is, as shown in FIG. 8, each communication hole 32a (32b) is elongate along the direction of circulating the temperature adjusting movable valve element 30. And, each communication hole 32a (32b) constitutes one side and the width in the short side direction (width along the axial direction of the temperature control movable valve body 30) is substantially constant, and each communication While constituting the other side of the hole 32a (32b), the lateral width gradually decreases toward the other end (the other end along the longitudinal direction) of the communication hole 32a (32b) (decreases in a taper shape). And a mixing communication part 32d.

  Further, when the temperature control valve device B is operated and each communication hole 32a (32b) overlaps with the corresponding through hole 51 (51) (when communicating), in each communication hole 32a (32b), The part that first intersects with the corresponding through hole 51 (51), that is, the “communication start end F of the communication hole 32a (32b)” is the following part. That is, in each communication hole 32a (32b), the other end portion along the circumferential direction of the temperature adjusting movable valve body 30 becomes this “communication start end portion F” (see FIG. 18). In other words, the pointed tip portion of the mixed communication portion 32d becomes the “communication start end portion M of the communication hole 32a (32b)”. In the following description, the “communication start end M of the temperature control movable valve element 30” is referred to as “movable communication start end M”. Then, the mixing communication portion 32d gradually increases its width toward “the other end side along the circumferential direction of the temperature adjusting movable valve body 30 in each communication hole 32a (32b)”, and the width reduction portion. A specific example of 32f (32g) is configured.

  In the temperature control valve device B, even if the temperature control handle T is fully operated to the high temperature side or fully operated to the low temperature side, the “communication start end F and the communication hole 32a (32b) The end G ”located on the opposite side does not intersect with the“ communication start end K on the fixed side ”.

  In the present embodiment, the communication channels 32H and 32W are not configured by a single communication hole, but a plurality of communication holes 32a and 32a (32b and 32b) provided at a predetermined interval. It is composed by. This is because the intrusion preventing portion 38 for preventing the seal member 55 from entering the inside of the temperature control movable valve body 30 is provided on the rear end side portion of the outer peripheral portion of the temperature control movable valve body 30 and the front end. This is intended to be provided at the site on the part side.

  That is, when the temperature control valve device B is operated and the temperature control movable valve body 30 is rotated with reference to the temperature control fixed valve body 20, as shown in FIGS. A portion 55a of the seal member 55 attached to the outer edge portion 52 of the outer peripheral portion 52 falls off from the “gap portion between the outer edge portion 52 of the attachment member 50 and the peripheral edge portion S of each of the attachment holes 23a, 23b”. There is a possibility of moving to the inner peripheral side of the adjustment movable valve body 30. At this time, if each of the communication flow paths 32H and 32W is a single large communication hole 39 (that is, if there is no entry preventing portion 38), this part 55a becomes the large communication hole 39. There is a high possibility of accidental entry. In addition, illustration of the mounting member 50 is abbreviate | omitted in Fig.11 (a).

  On the other hand, when the configuration of the present embodiment is adopted, as shown in FIGS. 10A and 10B, a part 55 a of the seal member 55 attached to the outer edge portion 52 of the attachment member 50 is “the attachment member 50 of the attachment member 50. Even if the outer edge portion 52 and the peripheral edge portion S of each of the mounted holes 23a, 23b drop off and try to move to the outer peripheral portion side of the temperature control movable valve body 30, this part 55a The intrusion prevention unit 38 is obstructed and is difficult to enter the communication channels 32H and 32W. For this reason, a part 55a of the seal member 55 can be prevented from entering the inside of the temperature control movable valve body 30. In addition, illustration of the mounting member 50 is abbreviate | omitted in Fig.10 (a).

  As described above, the temperature control fixed valve body 20, the temperature control movable valve body 30, and the spindle 40 are assembled to the housing 10 as follows. That is, starting from the front end portion of the spindle 40, this “integrated product” is inserted into the housing 10 through the opening 11 on the rear end side. Further, the spindle 40 is inserted into the opening 12 on the front end side of the housing 10 with the front end portion at the top, and the front end portion and the intermediate portion of the spindle 40 are projected forward of the housing 10. At this time, the protrusion 14 of the housing 10 and the positioning slit 25 are fitted. As a result, the “integral product” and the housing 10 are positioned along the circumferential direction of the housing 10.

  Then, the mounting collar 60 is mounted from the front end of the spindle 40 to the intermediate portion of the spindle 40, and the mounting ring 61 is mounted in the mounting groove 46. Thereby, the assembly of the components of the temperature control valve device B is completed, and the temperature control valve device B is completed. Thus, when the valve device B is completed, the spindle 40 is pivotally supported by the opening 12 while maintaining the water tightness between the inner wall of the opening 12 and the packing 44. For this reason, the spindle 40 and the temperature control movable valve body 30 can be rotated with reference to the temperature control fixed valve body 20. Further, when the valve device B is completed in this way, the inflow passage and the communication passage (7H and 32H, 5W and 32W) corresponding to each other are aligned in the axial direction of the temperature regulating fixed valve body 20. It becomes a state. Further, when the temperature control valve device B is mounted in the mounting space 1a of the faucet body 1 and the temperature control handle T is mounted on the spindle 40, the temperature control valve device B becomes usable.

  In this embodiment, the following temperature control can be performed with each operation applied to the temperature control valve device B. First, as shown in FIGS. 12A and 12B, when the operation position of the temperature adjustment handle T is in the neutral position, (1) the hot water supply side communication holes 32a and 32a (communication flow path 32H) are configured. The communicating portion 32d to be communicated with the through holes 51, 51 provided in the mounting member (hot water supply side mounting member) 50 mounted in the hot water supply side mounting hole 23a, and (2) communication on the water supply side The through holes 51 and 51 provided in the mixing communication part 32d which comprises the holes 32b and 32b (communication flow path 32W), and the attachment member (hot water supply side attachment member) 50 attached to the to-be-attached hole 23b on the water supply side Communicate with each other (see FIG. 13).

  When it is intended to increase the temperature of hot water flowing out from the outflow passage 33 of the temperature control valve device B, the temperature control handle T is rotated in one rotational direction. Thus, when the temperature control handle T is operated in one rotation direction, (3) a mounting member (a hot water supply side mounting member) mounted in the hot water supply side communication holes 32a and 32a and the hot water supply side mounting hole 23a. ) The degree of communication with the through holes 51, 51 provided in 50 (hereinafter referred to as “the degree of communication on the hot water supply side”) is improved, and (4) the communication holes 32b, 32b on the water supply side (communication flow path 32W). The degree of communication (hereinafter referred to as “water supply side”) with the through holes 51 and 51 provided in the mounting member (hot water supply side mounting member) 50 mounted in the mounting hole 23b on the water supply side "Communication") decreases. When the amount of rotation operation in one rotation direction is gradually increased, the “degree of communication on the hot water supply side” gradually increases and the “degree of communication on the water supply side” gradually decreases.

  The rate of change of the “degree of communication on the hot water supply side” and the “degree of communication on the water supply side” remains low while the amount of operation applied to the temperature control handle T is small. That is, in each communication hole 32a, 32a and the corresponding through hole 51 (51), the width on the communication start end K, F side gradually increases as the shape is separated from the communication start end K, F. Because of the tapered shape, while the amount of operation applied to the temperature control handle T is small, the rate of change of “degree of communication on the hot water supply side” and “degree of communication on the water supply side” remains at a low level.

  Then, as shown in FIG. 14, when the temperature adjustment handle T is rotated to a limit position in one rotation direction (high temperature water discharge direction), (5) hot water supply side communication holes 32a and 32a (communication flow path 32H). ) And the through holes 51 and 51 provided in the mounting member (hot-water supply-side mounting member) 50 mounted in the hot-water supply-side mounting hole 23a communicate with each other. ) The through holes 51, 51 provided in the water supply side communication holes 32b, 32b (communication flow path 32W) and the mounting member (hot water supply side mounting member) 50 mounted in the water supply side mounted hole 23b are not. Communication is established (see FIG. 15).

  When the temperature control handle T in the neutral position is operated in another rotational direction, the “degree of communication on the hot water supply side” is reduced and the “degree of communication on the water supply side” is improved. When the amount of rotation operation in other rotational directions is gradually increased, the “degree of communication on the water supply side” gradually increases and the “degree of communication on the hot water supply side” gradually decreases.

  Then, as shown in FIG. 16, when the temperature adjustment handle T is operated to a limit position in another rotational direction (low temperature water discharge direction), (7) water supply side communication holes 32b and 32b (communication flow path 32W). The "one-side communication portion 32c" that constitutes the communication hole and the through-holes 51, 51 provided in the mounting member (hot-water supply-side mounting member) 50 that is mounted in the mounting hole 23b on the water supply side communicate with each other. The hot water supply side communication holes 32a and 32a (communication flow path 32H) and the through holes 51 and 51 provided in the mounting member (hot water supply side mounting member) 50 mounted in the hot water supply side mounted hole 23a are not in communication. (See FIG. 17).

  In this embodiment, the temperature adjustment handle T can be rotated in one rotation direction and another rotation direction around the neutral position. And when operating in the operation range of the temperature control handle T (the rotation range, which is restricted between the limit position in one rotation direction and the limit position in the other rotation direction), At least one of the communication holes 32 a and 32 b is in a state of communicating with at least one of the through holes 51 and 51. The range (sliding range) in which the temperature control movable valve body 30 slides with respect to the temperature control fixed valve body 20 is regulated according to the operation range of the temperature control handle T.

  The temperature control valve device B of the present embodiment includes a simple configuration mainly composed of the temperature control fixed valve body 20 and the temperature control movable valve body 30, and therefore can be manufactured at low cost. The temperature control valve device B of the present embodiment is mainly composed of a temperature control fixed valve body 20 and a temperature control movable valve body 30 that slides in a watertight manner with respect to the temperature control fixed valve body 20. In addition, since the temperature is adjusted by adjusting the degree of communication of the inflow channels 7H and 5W with respect to the communication channels 32H and 32W, highly accurate temperature adjustment can be performed.

  In addition, according to the temperature control valve device B of the present embodiment, by selecting an operation amount of the temperature control handle T (sliding position of the temperature control movable valve body 30), “source hot water supply” and “original water supply water” are selected. Can be suitably performed. Therefore, according to this embodiment, it is possible to obtain a temperature control valve device B that is more convenient to use.

  Furthermore, according to the present embodiment, the shape, size, formation position, etc. of the opening (primary side end) of the communication flow paths 32H and 32W on the temperature regulating fixed valve body 20 side are selected, and each inflow flow path is selected. Various modes of temperature control can be realized by selecting the shape, size, formation position, and the like of the opening (secondary end) on the 7H, 5W temperature regulating movable valve body 30 side. This point will be described using a graph showing the water discharge temperature characteristic of FIG.

  FIG. 19 is an explanatory diagram showing the relationship between the rotation operation amount of the temperature control T and the water discharge temperature (temperature of hot water flowing out from the outflow passage 33). That is, in FIG. 19, the horizontal axis indicates the rotational operation amount (A to 9A) of the temperature adjustment handle T, and the vertical axis indicates the water discharge temperature (20 to 60 degrees Celsius). The explanatory diagram includes a graph (X0) related to the temperature control valve device of the comparative example, a graph (X1) related to the temperature control valve device B of the present embodiment, and a graph related to the temperature control valve device of the first modification. (X2) is illustrated. The rotation operation amount is indicated by “A” when “the temperature adjustment handle T is at the operation limit position on the low temperature side” and “when the temperature adjustment handle T is at the operation limit position on the high temperature side”. 9A ".

  Here, the temperature control valve device of the comparative example is the above-described lift-type temperature control valve device. Moreover, as shown in FIG. 20, the temperature control valve device of Modification 1 is different from that of the embodiment except that the width reduction portion 32g (32h) is different from the width reduction portion 32g (32h) of the embodiment. This is the same as the temperature control valve device B. That is, when the width reduction portions 32f and 32g (indicated by the solid line L2) of the first modification are compared with the width reduction portions 32g and 32h (indicated by the broken line L2) of the embodiment, the length (the longitudinal direction of the communication holes 32a and 32b) The length along the longitudinal direction of the communication holes 32a and 32b) is increased.

  In the temperature control valve device of the comparative example, “when the temperature control handle T is at the operation limit position on the low temperature side (when the rotation operation amount is A)”, the water discharge can be performed by slightly operating the temperature control handle T. The temperature rises rapidly. Further, “when the temperature adjustment handle T is at the operation limit position on the high temperature side (when the rotation operation amount is 9A)”, the water discharge temperature rapidly decreases by slightly operating the temperature adjustment handle T. For this reason, for a user, it becomes a temperature control valve device which is unusable and lacks a sense of security.

  On the other hand, in the temperature control valve device B of the embodiment and the temperature control valve device of the modification, “when the temperature control handle T is at the operation limit position on the low temperature side (when the rotation operation amount is A)” When the adjustment handle T is operated, the water discharge temperature gradually rises. In addition, when “the temperature control handle T is at the operation limit position on the high temperature side (when the rotation operation amount is 9A)”, when the temperature control handle T is operated, the water discharge temperature gradually decreases. For this reason, for the user, the temperature adjustment valve device B and the like are easy to use and rich in security.

  Further, in the temperature control valve device B of the embodiment and the temperature control valve device of the modification, temperature control of different modes can be realized by changing the mode of the communication holes 32a and 32b. That is, in the first modification, the lengths of the width reduction portions 32g and 32h are shortened and the width reduction rate is increased. For this reason, when the operation is performed on the “temperature control handle T at the operation limit position on the low temperature side”, the rate of increase of the water discharge temperature can be slightly improved as compared with the temperature control valve device B of the embodiment. Similarly, when an operation is performed on the “temperature control handle T at the operation limit position on the high temperature side”, the rate of decrease in the water discharge temperature can be slightly decreased as compared with the temperature control valve device B of the embodiment.
