Description

  The present invention relates to a hot and cold water mixing device.

  Conventionally, two open / close valves for independently performing hot water discharge and water discharge stop from two different water discharge parts, respectively, and opening / closing the two open / close valves independently. A hot and cold water mixing faucet device having two push buttons is known from Patent Document 1.

  In the conventional example shown in the above-mentioned Patent Document 1, two vertically long slanted vertical cylindrical portions that are inclined so as to be positioned forwardly at the front positions on both the left and right sides of the hot and cold water mixing portion are arranged apart from each other on the left and right. In addition, an opening / closing valve is inserted in each inclined vertical cylinder part, and a push button for opening / closing each opening / closing valve is arranged at the upper end of each inclined vertical cylinder part, except for the part where two push buttons are arranged The hot and cold water mixing section, the two inclined vertical cylinder sections arranged side by side are covered with a heat insulating cover section, and the upper end (the end in the axial direction) of the two inclined vertical cylinder sections arranged side by side are covered with a push button. It was.

  As described above, conventionally, the push button only covers the upper end portion of the vertically inclined vertical cylindrical portion, and other portions of the device other than the above are covered with the heat insulating cover portion. Therefore, the part covered with a heat insulation cover part increases, and the material of the heat insulation cover part has applied much.

  In addition, in the case where the upper end portion (the end portion in the axial direction) of the vertically long inclined vertical cylinder portion is covered with the push button, the area of the end portion in the axial direction of the vertically long inclined vertical tube portion is small. If the size is large enough to cover the end in the axial direction of the vertically long inclined vertical cylindrical portion, the operation area is too small.For this reason, to improve the operability, the area of the push button is set at the upper end of the inclined vertical cylindrical portion. It is larger than the area. Therefore, in the above conventional example, the vertically long inclined vertical cylinder portion is vertically long, and the push button is long in the horizontal direction (left-right direction or front-rear direction), which is a direction intersecting the axial direction of the inclined vertical cylinder portion. There is a problem that the apparatus becomes long in both the vertical direction and the horizontal direction, resulting in an increase in size.

In particular, in the case where the vertically long inclined vertical cylinder parts are separated from each other on the left and right sides, the part covered with the heat insulating cover part becomes wider and the entire apparatus becomes larger, and the material of the heat insulating cover part takes more, and the cost is high. It was.

It is provided along the axial direction and has a lateral length extending from the axially outer end of the front end of the mounting portion 27 to the intermediate portion of the cylindrical body 20 in the axial direction. The front surface of the cylindrical body portion 20 is covered by the rear end portions of the two operation portions 4 provided. Most of the operation parts 4 except for the rear end part are substantially flat, the upper part is an operation part 4a for pushing down, and the lower part is an operation part 4b for pushing up. The rear end portion is a cover portion 28 having an arcuate cross section for covering one axial half of the front surface of the cylindrical body portion 20 along the front surface of the outer peripheral portion of the cylindrical body portion 20.

  Each operation unit 4 is movable only in the vertical direction so that only upward push-down and downward push-down operations are possible, and each lever handle 3 is in a state where the operation unit 4 is raised or lowered, respectively. Open the corresponding rotary valve 23 (that is, the state in which the hole 26 of one rotary valve 23 and the one outflow hole 22a communicate with each other, or the hole 26 and the other outflow hole of the other rotary valve 23). 22b is in communication) and the other is closed (that is, the state in which the hole 26 of one rotary valve 23 and one outflow hole 22a are not in communication, or the hole 26 of the other rotary valve 23 and the other. The outflow hole 22b is in a non-communication state. And between the said open position A and the closed position B of each operation part 4 is the water quantity adjustment area C which adjusts the flow volume of the hot water discharged from the corresponding water discharging part 2. FIG.

  The operation part 4 of the lever handle 3 has the same or substantially the same cross-sectional shape as the operation part 19 for adjusting the hot water temperature of the lever handle 18 for adjusting the hot water temperature.

  In the present invention, as described above, since the operation portion 4 of the lever handle 3 protrudes along the axial direction of the cylindrical body portion 20, it can be made thin in the vertical direction. Since it follows the direction, it can be lengthened in the left-right direction, improving operability.

  The unitized hot / cold water mixing unit 1 and the unitized valve mechanism unit 9 are attached to the base 10 by fixing them with the screw tool 29, respectively.

  Here, as shown in FIG. 1, the central axis of the cylindrical portion 13 of the unitized hot water / mixing portion 1 and the central axis of the cylindrical portion 20 of the unitized valve mechanism 9 are coaxial and unitized. The hot and cold mixing unit 1 and the unitized valve mechanism unit 9 are attached to the base body 10 so as to be coaxially adjacent to each other.

  In this case, a hot water temperature adjusting lever handle 18 of the cylindrical portion 13 of the hot water mixing portion 1 is provided on one axial end surface of the cylindrical body portion 20 of the unitized valve mechanism portion 9 via one lever handle 3. The other end surface that is not present is adjacently disposed.

  Further, the hot water outflow portion 16 and the inflow hole portion 21 are connected in communication by a connection pipe 34.

  Further, a water supply connection pipe 14a is connected to the water inflow part 14, a hot water supply connection pipe 15a is connected to the hot water inflow part 15, and the outflow pipes 45a and 45b are respectively connected to the two outflow holes 22 (22a and 22b). Connect. One of the outflow pipes 45a and 45b, in FIG. 3 and FIG. 4, the outflow pipe 45a has a water discharge part 2 (curan water discharge part 2a) as it is, and is disposed directly below one of the outflow holes 22a. And it is designed to discharge water downward.

  A heat insulating cover portion 11 is further attached to the base body 10, and the heat insulating cover portion 11 connects the cylindrical body portion 20 of the valve mechanism portion 9, the mounting portion 27 at the rear end portion of both lever handles 3, and the cylindrical portion 13 of the hot water / water mixing portion 1. It comes to cover.

  The heat insulating cover portion 11 has a front opening portion 31 provided on the front surface portion, and the operation portions 4 provided at the front portions of the lever handles 3 protrude forward from the front opening portion 31 and protrude forward. Each operation unit 4 can be moved up and down so that it can be pushed up and down, and each operation unit 4 can be pushed up and down. As a result, each lever handle 3 can be rotated about the axis of the cylindrical portion 20. There is no particular limitation on the rotation angle of the lever handle 3 when the operation unit 4 is pushed up or down, but a rotation range of 45 ° is taken as an example.

  The front opening 31 provided on the front surface of the heat insulating cover 11 has a horizontal length that is the same as the axial length of the cylindrical body 20, and the horizontal width of the mounting portion 27 (the axial direction of the cylindrical body 20. The width is twice the length in the direction parallel to the length.

  The front opening 31 of the heat insulating cover portion 11 is shielded by a cover portion 28 provided at the rear end of the operation portion 4 of each lever handle 3, so that even if the lever handle 3 is rotated, the cylinder body The front surface of the portion 20 is covered with the cover portion 28 without being exposed to the outside. As a result, the cover portion 28 also serves as a heat insulating cover that covers a part (front portion) of the cylindrical body portion 20, reducing the area covered for heat insulation by the heat insulating cover portion 11, and reducing the material of the heat insulating cover portion 11. Less.

  Therefore, the cylindrical body part 20 and the attachment part 27 of the operation part 4 are covered with the heat insulating cover part 11 and the cover part 28, and this part is not exposed to the outside in the construction state.

  Moreover, the heat insulation cover part 11 covers the cylinder part 13 of the hot water / water mixing part 1 so that the cylinder part 13 is not exposed to the outside in the construction state, and further covers the hot water / water mixing part 1 of the heat insulation cover part 11. A dummy operation portion 33 that is integrally formed in a substantially flat plate shape protrudes forward from the front portion of the existing portion.

  Here, the cross-sectional shape of the dummy operation portion 33 is the same as or substantially the same as the operation portion 4 and the operation portion 19 for adjusting the hot water temperature, but protrudes integrally from the heat insulating cover portion 11. Therefore, even if a pressing force or a pressing force is applied, the insulating cover portion 11 does not move.

  Further, the lateral length of the dummy operation portion 33 is the same as or substantially the same as the axial length of the cylindrical portion 13, and the dummy operation portion 33 is connected to the hot water of the aforementioned hot water temperature adjusting lever handle 18. The temperature adjusting operation unit 19 is interposed between one operation unit 4 a of the operation units 4 of the two adjacent lever handles 3. In this manner, by interposing the dummy operation portion 33 between the operation portion 4 of the lever handle 3 and the operation portion 19 for adjusting the hot water temperature of the lever handle 18 for adjusting the hot water temperature, the operation portion 19 can be operated. The dummy operation unit 33 is arranged so that the operation unit 19 is not operated by mistake when operating the operation unit 19 for adjusting the hot water temperature or by operating the operation unit 19 by mistake when operating the operation unit 19 for hot water temperature adjustment. Serves as a partition.

  The operation portions 4 of the lever handles 3 are flush with each other when the operation portions 4 are in the closed position B, and the upper surface is the dummy operation portion 33 when the operation portion 4 is in the closed position B. It is set to be flush with the upper surface. In the embodiment shown in FIGS. 1 to 5, the position where each operation unit 4 is pushed down to the maximum (the lowest position, the position indicated by the solid line in FIGS. 3 and 4) is the closed position B, and each operation unit 4 is The position pushed up to the maximum (the uppermost position, the position indicated by the two-dot chain line in FIGS. 3 and 4) is the fully open position A.

  Further, the operation part 19 for adjusting the hot water temperature of the lever handle 18 for adjusting the hot water temperature is such that the upper surface of the operation part 19 for adjusting the hot water temperature is flush with the upper surface of the dummy operation part 33. It is set to be 40 ° C. Accordingly, the operation portion 19 for adjusting the hot water temperature of the lever handle 18 for adjusting the hot water temperature is flush with or substantially the same as the upper surface of the operation portion 19 for adjusting the hot water temperature of the lever handle 18 for adjusting the hot water temperature. It is possible to understand at a glance whether or not the hot water temperature is about 40 ° C., which is the average hot water temperature in normal use, at a glance simply by looking at whether or not they are the same. Further, the hot water temperature can be easily set to about 40 ° C. simply by making the hot water temperature adjusting operation portion 19 of the hot water temperature adjusting lever handle 18 flush with the dummy operating portion 33. It is like that.

  Then, from the state in which the operation part 19 for adjusting the hot water temperature is flush with the dummy operation part 33, the operation part 19a for pushing down the hot water mixing on the upper surface part is pushed down, or the hot water mixing on the lower surface part is performed. By pushing up the push-up operation part 19b, the hot water temperature adjusting lever handle 18 is rotated around the central axis of the cylindrical part 13 of the hot water mixing part 1 to raise the hot water temperature from about 40 ° C. The hot water temperature can be adjusted to be lower than about 40 ° C.

  The hot and cold water mixing faucet device 6 configured as described above connects a water pipe to the water supply connecting pipe 14a and connects the hot water supply pipe to the hot water connecting pipe 15a.

  Moreover, the hot and cold water mixing faucet device 6 of the embodiment shown in FIGS. 1 to 5 shows an example of setting in a bathroom or a bathroom vanity, and one end of a shower hose 35 is connected to the other outflow pipe 45b. The shower head 36 at the other end of the shower hose 35 is the other water discharge part 2 (shower water discharge part 2b).

  In the use of the hot and cold water mixing faucet device 6 constructed as described above, when discharging or stopping the water flowing out of the currant water discharging portion 2a, the operation portion 4 of one lever handle 3 is pushed up and down. In addition, when water is discharged or stopped by the shower water discharge portion 2b, the operation portion 4 of the other lever handle 3 is pushed up and down. Then, the push-up operation and push-down operation of the operation unit 4 of each lever handle 3 can be performed independently, and both the operation units 4 can be pushed up or down simultaneously. Therefore, when both the water discharge unit 2a and the shower water discharge unit 2b are in the water-stopped state, water discharge from only one of the water discharge unit 2a and the water discharge unit 2b, or both the water discharge unit 2a and the water discharge unit 2b of the shower. At the same time, the operation of water discharge can be easily performed. In addition, when both the karan water spouting unit 2a and the shower water discharging unit 2b are in the water discharging state, the water stoppage of only one of the kalan water discharging unit 2a and the shower water discharging unit 2b, or both the kalan water discharging unit 2a and the shower water discharging unit 2b At the same time, it is easy to stop water.

  And in this invention, since each operation part 4 is the operation in which the pushing-down operation and the pushing-up operation are the opposite directions, even if it is groping, by putting a hand on the operation part 4 and carrying out pushing-up operation or pushing-down operation, Even if you do not check directly with your eyes, you can operate without error, and as you can see, each operation part is opened and closed by pushing up and pushing down, so when washing your hair with shampoo etc. Even when the operation part 4 of the lever handle 3 is searched and searched without looking at the hot water / water mixing faucet device 6 with the eyes as in the case of being operated, there is no erroneous operation.

  For example, when the shower water spouting unit 2b is still water and the karan water spouting unit 2a is in the state of water spouting, and the face is washed with soap or the like, the karan water spouting unit 2a is used to stop the water for the karan water spouting unit 2a. When searching for the operation unit 4 (operation unit for currant) and performing a water stop operation, the shower water discharge unit 2b is already stopped even if the shower operation unit 4 is erroneously operated to the water stop side. Therefore, there is no fear that water is suddenly discharged from the shower water discharger 2b.

  Further, when the shower water discharger 2b is water discharge and the currant water discharger 2a is in a water stoppage state and the hair is washed with a shampoo or the like, the shower water discharger 2b is used to stop the water for the shower water discharger 2b. When the shower operation unit 4 is operated to the water stop side, even if an attempt is made to accidentally operate the curan operation unit 4 to the water stop side, the water is already stopped, so the water is suddenly discharged from the water discharge unit 2a. There is no such a fear.

  Therefore, when searching for and operating a plurality of operation units 4 by hand search, even if the operation direction of the operation unit 4 is not wrong even if the above-described erroneous operation is performed, the water discharge unit which is not expected even by hand search No sudden water discharge from 2 will occur, and you can wash your face and hair with peace of mind.

  In addition, for example, when one of the two water dischargers 2 forgets to stop the water while discharging hot water from one of the two water dischargers 2, the water is discharged from one water discharger 2. If you notice and panic and try to operate the operation part 4 on the one water discharge part 2 side to the water stop side, since it is rushing, even if you accidentally operate the operation part 4 of another water discharge part 2 to the water stop side The situation where water is suddenly discharged from another water discharge part 2 does not occur.

  As described above, water is discharged from each water discharger 2 and water is stopped by pushing up and down the operation part 4 of each lever handle 3, and the amount of movement of each operation part 4 in the vertical direction is set. By adjusting, the flow volume of the hot water discharged from each corresponding water discharging part 2 can be adjusted simultaneously.

  Therefore, in the present invention, a plurality of flow rate adjusting valves as separate members and a plurality of operation units for operating the same are not required corresponding to the plurality of water discharge units 2, and It is possible to reduce the size and the number of parts. Moreover, since the water discharge from the water discharge part 2 corresponding to only the movement of each operation part 4 to the up-down direction, water stop, and flow volume adjustment can be performed simultaneously, operativity improves.

  In addition, since the plurality of lever handles 3 are separate from the hot water temperature adjusting lever handle 18, when the plurality of lever handles 3 are independently operated, the temperature of the hot water is mistakenly operated when any lever handle 3 is operated. There is no danger of hot or cold water being discharged.

  Further, in the embodiment shown in FIGS. 1 to 5, the position where the operation parts 4 are pushed down to the maximum (lowermost position) is the closed position B, and the position where each operation part 4 is pushed up (the uppermost position). Is in the fully open position A. Even if the operation unit 4 is accidentally hit with each operation unit 4 individually or at the same time, and the pressing force acts from above, the operation unit 4 is originally in the closed position or in the open position. However, since it is pushed down to the closed position, there is no fear that water is unexpectedly discharged from the plurality of water discharging portions 2. Further, in this embodiment, the closed position B is substantially horizontal and is substantially flush with or substantially flush with the dummy operating portion 33 in a substantially horizontal posture. In this case, below the hot and cold water mixing faucet device 6 The water discharge space on the side of the water discharge part 2a is wide and easy to see. The operation part 4 is pushed upward to discharge water from the water discharge part 2a, and the hot water discharged from the liquid discharge part 2a is used. In doing so, the operation unit 4 does not get in the way, and the use of the currant water spouting unit 2a is convenient.

  Of course, in the hot and cold water mixing faucet device 6 of the present invention, as in the embodiment shown in FIG. 6, the position at which each operation section 4 is pushed down to the maximum (lowermost position) is the fully open position A, and each operation section 4. The position where the button is pushed up to the maximum (uppermost position) may be the closed position B. In this case, for example, when the closed position B is substantially horizontal and is substantially flush with the dummy operation part 33 in a substantially horizontal posture, the operation part is placed in the space above the hot water and water mixing faucet device 6. 4 does not protrude, and this portion is not obstructed by the operation unit 4 and can be used for another purpose or as a wide space.

  Moreover, in each said embodiment, the two valve means 7 for performing the water discharge from two water discharge parts 2 and a water discharge stop each independently, and for opening and closing these two valve means 7 each independently Although the example of the hot and cold water mixing faucet device 6 provided with two lever handles 3 has been described, as shown in FIGS. 7 to 10, there is one water discharge part 2, one valve means 7, and one lever handle 3. It may be one. In this embodiment, the basic structure is the same except for the configuration of the valve mechanism 9.
