As shown in FIGS. 1 to 3, the water purifier and the hot water heater cock according to the present invention include a cock body 4 provided in a water purifier, a cold / hot water generator (not shown) and having a water outlet 8 through which water is discharged, An upper valve V1 installed on a main shaft 20 covered with a cover packing 18 for opening and closing an internal passage formed in the cock body 4 and supported by an elastic member S1, A lower valve V2 inserted in the hollow H of the main shaft 20 and provided on the sub shaft 26 to open and close the outlet 8 of the cock body 4 and a lower valve V2 mounted on the hinge 13 of the main shaft 20, A water supply lever 14 connected to the hinge pin 12 and installed to use the cock body 4 as a pedestal; a water supply lever 14 connected to the sub shaft 26 in a state of being inserted into the through hole 24 of the main shaft 20; And a safety button 16 provided on one side of the cock body 4 so as to press or return the safety shaft 22 that controls lift and elevation.

The safety shaft 22 is provided with an opening guide groove 30 formed at one side so as to engage with the upper end of the sub shaft 26 and an opening guide groove 30 at a side perpendicular to the plane in which the opening guide groove 30 is formed. A holding groove 40 is formed.

The opening-state holding groove 40 is a groove formed so that an upper end of the opening can be inserted when the sub shaft 26 rises.

2, the safety shaft 22 is provided with a safety button 16 for selectively selecting the opening guide groove 30 and the opening state holding groove 40 at one end thereof. The safety shaft 22 is rigidly assembled to the safety button 16 and has a rectangular cross-section so as not to hang loose.

The safety button 16 is assembled to the button fixing ring 17 assembled to the cock body 4 and is assembled so that the rotation can be restricted by the locking protrusion 17J. The safety button 16 is formed with a rotation guide groove 16G so as to rotate the safety button 16 clockwise and counterclockwise with respect to the locking projection 17J.

The locking protrusion 17J is formed below the inner circumferential surface of the button retaining ring 17 so as to restrict the rotation direction of the safety button 16 and accurately rotate the safety button 16. [

The rotation guide groove 16G is a groove corresponding to the locking projection 17J and is a groove for allowing the safety button 16 to rotate without coming off the locking projection 17J.

This rotation guide groove 16G enables selection of the case of operating both the water supply lever 14 and the safety button 16 and the case of operating only one water supply lever 14 without operating the safety button 16. [

In order to confirm the use of the safety button 16, "?" Is displayed on the safety button 16, so that only the water supply lever 14 is operated and the safety button 16 is not used. Quot; is displayed on the button 16.

&Quot; "and" "of the safety button 16 are displayed so as to promptly confirm whether or not the safety button 16 is used.

The control shaft 27 is inserted into the opening guide groove 30 of the safety shaft 22 or the opening state retaining groove 40 and formed on the upper end of the sub shaft 26.

The control projection 27 is inserted into the opening state holding groove 40 which is in contact with the surface of the safety shaft 22 and is caught or rotated by the opening guide groove 30 moving when the sub shaft 26 moves up .

When the control projection 27 is inserted into the opening guide groove 30 or the opening state holding groove 40 of the safety shaft 22, the sub shaft 26 is moved upward and the lower valve V2 is moved to the outlet 8 .

The sub shaft 26 is formed with a support plate P2 for supporting the elastic force of the elastic member S3. The support plate (P2) facilitates the installation of the elastic member (S3) provided inside the outlet (8). That is, the sub shaft 26 supported by the elastic member S3 via the support plate P2 is rapidly raised by the expansion of the elastic member S3 when the main shaft 20 is lifted, The elastic member S3 is lowered while pressing the elastic member S3 so that the inside of the outlet 8 is opened and closed so as not to be contaminated.

The sub shaft 26 is assembled with a seal ring R to improve the sealing between the sub shaft 26 and the hollow H when the main shaft 20 is inserted into the hollow shaft H. [ The seal ring R is assembled to the joint portion of the parts other than the sub shaft 26 where leakage prevention is required.

The main shaft 20 is installed in the upper part of the inside of the cock body 4 so as to press or expand the elastic member S1 when the water supply lever 14 is operated.

In addition, the elastic member (S3) is installed so that elastic force acts upward in the inner periphery of the outlet (8). The resilient member S3 is urged such that the resilient force acts upward on the inner periphery of the outlet port 8 so that the pressing projection P1 of the main shaft 20 can easily press the supporting plate P2 of the sub shaft 26 So that the lifting operation of the sub shaft 26 can be accurately performed.

The main shaft 20 controls the up and down movement of the sub shaft 26. That is, the main shaft 20 is provided with a pressing projection P1 for pressing the supporting plate P2 of the sub shaft 26 below the upper valve V1 for opening and closing the inner passage of the cock body 4 .

The pressing projection P1 presses the supporting plate P2 of the sub shaft 26 when the main shaft 20 is lowered by the return of the water supply lever 14. [ The structure in which the pressing projection P1 presses the supporting plate P2 allows the safety shaft 22 and the safety button 16 to be accurately returned by the elastic member S2.

On the other hand, when the water purifier and the cold / hot water machine cock are provided with a water purifier and a cold / hot water machine in a childless office or a conference room, if only the safety button 16 of the cock is turned, only the water supply lever 14 is operated So that hot water can be taken.

That is, when the water supply lever 14 is operated, the upper and lower valves V1, V2 in the cock body 4 are operated by the operation of the water supply lever 14 when the safety button 16 is not used When the main shaft 20 and the sub shaft 26 move up and down, the inner passage of the cock body 4 and the outlet port 8 are simultaneously opened or shut off.

Although the above cock is described for the hot water, if the components relating to the safety button 16 and the safety shaft 22 are omitted, they can be used for cold water, and a detailed description thereof will be omitted.

Hereinafter, the operation of the present invention as described above will be described with reference to FIG. 4 to FIG.

First, when the water supply lever 14 and the safety button 16 are operated, the water supply lever 14 of the cock is pushed in a general case where water supply is possible.

When the water supply lever 14 is pushed, the main shaft 20 ascends while pressing the elastic member S1. When the main shaft 20 is raised, the upper valve V1 opens the inner passage at the upper inside of the outlet 8. When the upper valve V1 opens the internal passage, the introduced hot water is supplied to the inside of the outflow port 8 up to the inside.

When the main shaft 20 is lifted up, the sub shaft 26 is stopped and can not be lifted because the upper end of the sub shaft 26 is hooked on the safety shaft 22. Accordingly, the lower valve V2 of the sub shaft 26 prevents the discharge of the hot water against the erroneous operation of the water supply lever 14 and also keeps the outlet 8 in order to prevent the outlet 8 from being contaminated.

Thereafter, when the safety button 16 is pushed, the safety shaft 22 is pushed back and the opening guide groove 30 is also moved. As the opening guide groove 30 moves, the sub shaft 26 which has received the elastic force of the elastic member S3 is moved upward. When the sub shaft 26 is lifted, the upper control projection 27 is inserted into the opening guide groove 30 and is engaged. The safety shaft 22 caught by the control projection 27 presses the elastic member S2 through the safety button 16 until it is separated from the control projection 27. [

When the sub shaft 26 is lifted, the lower valve V2 opens the outlet 8 so as to discharge the hot water.

When the discharge of the hot water through the outlet port 8 is completed, the operation of the water supply lever 14 is stopped. Accordingly, the water supply lever 14 is returned as the pushing force is removed.

When the water supply lever 14 returns, the main shaft 20 is lowered by the elastic member S1 and the inner passage of the cock body 4 is blocked by the upper valve V1. As the inner passage is blocked by the upper valve V1, the hot water can not enter the outlet 8 side and is shut off.

When the upper valve V1 blocks the internal passage, the pressing projection P1 under the upper valve V1 presses the supporting plate P2 of the sub shaft 26. [

When the support plate P2 is pushed by the pressing projections P1 of the main shaft 20 and the sub shaft 26 is lowered, the sub shaft 26 is lowered while pressing the elastic member S3.

When the sub shaft 26 is lowered, the lower valve V2 closes the outlet 8 so that hot water is not discharged. The lower valve V2 prevents the inside of the outlet 8 from being exposed, thereby preventing contamination of the outlet 8 due to dust and foreign matter.

Further, when the sub shaft 26 is lowered, the control projection 27 is separated from the opening guide groove 30 of the safety shaft 22. When the control projection 27 is detached, the safety shaft 22 is returned by the elastic force of the elastic member S3 acting on the combined safety button 16. As a result, the cock is switched to the state before use.

On the other hand, when the water purifier and the cold / hot water system are installed in a childless office or a conference room and the water supply lever 14 is to be operated only by operating the safety button 16, the safety button 16 is rotated counterclockwise Rotate to move the "ㅧ" mark to the right.

The rotation of the safety button 16 causes the safety shaft 22 to turn to the left with the shaft guide 22G assembled to the shaft support 36 as the center.

The opening state holding groove 40 is positioned at the upper end of the sub shaft 26 as the safety shaft 22 is turned to the left.

As described above, when the water supply lever 14 is pushed while the safety button 16 is rotated, the main shaft 20 moves upward while pressing the elastic member S1.

When the main shaft 20 is raised, the upper valve V1 opens the upper internal passageway of the outlet port 8. As the inner passage is opened by the upper valve V1, the hot water flows into the upper inner passage of the outlet 8.

The sub shaft 26 pressed by the pressing projection P1 pressing the support plate P2 is removed at the same time as the main shaft 20 is raised.

As a result, the sub shaft 26 is raised by the expansion force of the elastic member S3 and the lower valve V2 is also raised. As the lower valve V2 rises, the outlet 8 is opened.

That is, when the water supply lever 14 is pushed, the main shaft 20 and the sub shaft 26 simultaneously rise, and the internal passageway and the outlet port 8 are simultaneously opened. When the inner passage and the outlet port 8 are opened, the hot water is discharged directly through the outlet port 8.

When the discharge of the hot water through the above-described process is completed, the operation of the water supply lever 14 is stopped. The water supply lever 14 is returned to the position before the operation as the operation force is removed.

When the water supply lever 14 is returned, the main shaft 20 is lowered by the elastic member S1 and the sub-shaft 26 ). That is, the main shaft 20 and the sub shaft 26 are simultaneously lowered.

When the main shaft 20 is lowered, the upper valve V1 prevents the hot water from flowing through the inner passage in the upper portion inside the water outlet 8. [

When the sub shaft 26 is lowered, the lower valve V2 blocks the discharge of the hot water by blocking the outlet 8. Accordingly, when the lower end of the outlet 8 is blocked by the lower valve V2, the outlet 8 is not exposed to the outside, thereby preventing contamination by dust and foreign matter.

As described above, since the descent of the main shaft 20 and the sub shaft 26 is performed at the same time, the hot water is blocked at the same time.
