The movable disk (2) is moved away from the hole of the fixed disk so that hot water and cold water can flow out through the holes (11, 22) in the side wall of the housing, respectively. And cold water respectively can flow out through the holes (9) in the end wall (7).

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mixing cock having a housing provided with a ceramic disk for adjusting the ratio and volume of the mixture.

[0002]

[Prior art and its problems]

 UK Patent Application No. No. 2,108,634A discloses a mixing cock having a fixed ceramic disk and a ceramic disk movable and rotatable with respect to the fixed disk, by which the ratio and volume of the mixture can be adjusted. ing. The movable disk has two holes that interwork with holes in the fixed disk, which separate the hot and cold water paths. Hot water and cold water are both supplied and discharged through holes in the end wall of the mixing cock.

The aim of the present invention is to show a means by which the production cost can be reduced and at the same time the mixing cock can be made smaller.

[0004]

[Means for Solving the Problems]

 According to the present invention, the above-mentioned problem is solved in a mixing cock provided with a housing having a ceramic disk for adjusting the ratio and amount of the mixture, by providing three holes corresponding to the holes of the end wall of the housing. And a movable disk made of ceramic, which is movable and rotatable with respect to the fixed disk by a rotation / push mechanism controlled by a single protruding handle. The disk has a single hollow space that does not have the ability to extend beyond the fixed disk, the flow paths for cold water and hot water can be completely separated, and hot water and cold water can be respectively provided in the holes of the fixed disk. The movable disk is moved away from the hole in the fixed disk and hot and cold water respectively flow out through the hole in the side wall of the housing. And is solved by providing a mixing cock, characterized in that hot water and cold water can each flow out through a hole in the end wall.

【Example】

 The present invention will be further described below with reference to the accompanying drawings.

The mixing cock shown in FIG. 1 comprises an outer housing 6 having an end wall 7, and three holes 8, 9, 10 are provided in said end wall, and one hole 11 is mentioned above. Offered in the side wall.

8 is a hole communicating with a pipe for supplying hot water, while 10 is a hole communicating with a pipe for supplying cold water, and 9 and 11 are outlets for cold water and hot water, respectively.

The adjusting mechanism comprises a fixed ceramic disc 1 having three holes 12, 13, 14 corresponding to the holes 8, 9, 10 in the side wall 7.

The packing 15 provides a seal between the three holes 12, 13, 14 in the fixed ceramic disk. The packing 16 provides a seal between the holes 8, 9, 10 in the end wall 7.

The fixed ceramic disk 1 has its three holes 12, 13, 14 always corresponding to the three holes 18, 19, 20 of the inner housing and the three holes 8, 9, 10, of the outer housing. Fixed in the housing.

The second ceramic disk 2 can be moved and rotated with respect to the fixed ceramic disk 1 by rotating / pushing mechanisms 3, 4, 5.

The inlet 14 for cold water in the fixed ceramic disk 1 corresponds to the outlet 13 through the hollow space 21 in the movable ceramic disk 2. The movement of the disk 2 is restricted so that the hollow space 21 never extends beyond the fixed disk 1 and cannot communicate with the holes 12 for hot water in the disk 1. By limiting the movement of the disk 2 as described above, hot water is always separated from cold water. As the movable disk 2 moves away from the hole 12, hot water is free to drain through the holes 22 and 11 in the inner housing and outer housing, respectively.

Thus, a single-handle mixing cock has been provided, which only comprises two disks, in which the separation of hot and cold water is maintained, the cold water being movable. The hot water flows through the hollow space 21 in the disk, while the hot water flows through the holes in the fixed disk directly through the fixed disk. This hole is opened by moving the movable disk away from the hole in the fixed disk.

As shown in FIGS. 3, 4, 5, 7, 8 and 9, the two disks change the mixing ratio of hot water and cold water by the rotation of the movable disk, while the two disks move in the radial direction. Is formed by a method in which the total flow rate is changed.

It should be noted that in the closed position it is possible to rotate the adjusting handle without draining water from the mixing cock.

According to the invention, it is thus possible to maintain the separation of hot and cold water by means of a relatively simple structure with a small ceramic disk.

The mixing cock according to the invention can be modified in many ways without departing from the scope of the invention.
