The O-ring (O / R1) coupled to the outer surface of the valve 68 is coupled to the outer peripheral seat groove 68a of the valve 68.

As a result, the valve 68 adjusts the opening degree of the hot water inlet 11 and the cold water inlet 12 while making the horizontal movement only when the temperature control handle 40 is rotated.

The ring 69 is also threaded with the element guide 62 which causes the valve 68 to slip without rotation when the element guide 62 is rotated and thus the flow adjustment handle 50, It is possible to operate smoothly without tightness.

The unit shaft 80 serves to rotate the thermostat unit 60 when the flow adjustment handle 50 rotates.

The unit shaft 80 has a receiving portion 81 to which the one end portion 62b of the element guide 62 is received while being accommodated and is disposed in the second body 20.

Since the one end portion 62b of the element guide 62 and the receiving portion 81 are coupled to each other in a hexagonal shape rather than a circular shape, the thermostat unit 60 can be rotated at the same time Can be rotated together.

As shown in Fig. 6, an O-ring (O / R2) is provided as a means for preventing water or foreign matter from penetrating to the outside of the unit shaft 80 as well.

The spring guide 65 is a structure in which the both ends of the spring guide 65 are connected to the element guide 62 and the rotary switch plate 33 of the thermostat unit 60 in the first body 10.

A plurality of guide ribs 65a are formed in the spring guide 65 so that the spring guide 65 is interconnected with the element guide 62 and a plurality of guide ribs 65a are coupled to the element guide 62 The rib groove 62a is formed.

A return spring 67 is elastically biased between the spring guide 65 and the element guide 62 in the direction in which the spring guide 65 is expanded between the element guides 62.

A plurality of coupling protrusions 65b are formed in the spring guide 65 so that the spring guide 65 is connected to the rotation opening and closing plate 33. A plurality of coupling protrusions 65b are formed in the rotation opening and closing plate 33 A plurality of projecting grooves 33a are formed.

The flow adjustment handle guide 51 is a portion that is coupled with the flow adjustment handle 50 and rotates together with the flow adjustment handle 50 at the same time.

The flow control handle 50 is engaged with the flow control handle guide 51 by the bolt B1 inserted through the right end of Figure 6 so that the flow control handle 50 ) Are also rotated together.

A handle spring 66 is further provided between the flow control handle 50 and the flow control handle guide 51 so as to be elastically biased in a direction to expand at the corresponding position. Is returned to the temperature regulating handle 40, the flow regulating handle 50 is restored to its original position.

The flow rate adjusting stem 52 is connected to the flow rate adjusting handle guide 51 and rotates together with the flow rate adjusting handle guide 51. The flow rate adjusting stem 52 eventually rotates the unit shaft 80.

One end of the flow control stem 52 is connected to the flow control handle guide 51 and the other end is disposed in the second body 20.

The temperature regulating stem 44 is disposed radially outward of the flow regulating stem 52 and is connected to the temperature regulating handle 40 and rotated together with the temperature regulating handle 40 at the same time.

One end of the guide 85 is in contact with the unit shaft 80 and the inner wall surface is screwed with the temperature regulating stem 44 on the outside of the temperature regulating stem 44.

The guide 85 can be advanced or retracted as a result of which the valve 68 is screwed with the temperature regulating stem 44. As a result, So that the inflow amount of cold water and hot water can be controlled.

The clutch 70 is further provided in the space between the flow control handle guide 51 and the flange portion 40a of the temperature control handle 40 in this embodiment.

The clutch 70 is a means for allowing the flow control handle 50 to be rotated alone or rotated simultaneously with the temperature control handle 40 during the rotation operation of the flow control handle 50. [

That is, the clutch 70 is disposed in the space between the flow control handle guide 51 and the flange portion 40a of the temperature control handle 40 so that the flow control handle guide 51 and the flange portion 40a of the temperature control handle 40, (Not shown).

The flow control handle 50 is rotated toward the temperature control handle 40 so that the clutch 70 is engaged with the flange portion 40a of the temperature control handle 40, The temperature regulating handle 40 is simultaneously rotated with the flow regulating handle 50 when the flow regulating handle 50 is rotated so that the temperature is regulated and the rotation opening and closing plate 33 is not rotated at this time.

On the other hand, when the flow adjustment handle 50 is rotated independently without pressing the flow adjustment handle 50 toward the temperature adjustment handle 40, the clutch 70 is engaged with the flange portion 40a of the temperature adjustment handle 40 Only the flow rate adjusting handle 50 is rotated independently to induce the rotation of the rotary switch plate 33 to adjust the discharge flow rate.

The clutch 70 performing this role is connected to the flow control handle 50 by the bolt B2.

That is, the bolt B2 is inserted through the bolt hole 50a of the flow control handle 50, and then is fastened to the bolt fastening portion 70a of the clutch 70.

5, the clutch 70 and the flow control handle guide 51 are meshed with gears, the clutch 70 and the flange portion 40a of the temperature control handle 40 are meshed with a triangular gear, But the present invention is not limited thereto.

The operation of temperature control and flow rate adjustment of the thermostat cartridge apparatus having such a configuration will be described below.

The flow control handle 50 is pressed in the direction of the arrow so that the clutch 70 is engaged with the flange portion 40a of the temperature control handle 40. At this time, .

In this case, since the temperature adjusting stem 44 is mutually screwed with the guide 85, the temperature adjusting stem 44 is rotated in the same direction as the temperature adjusting stem 44, The guide 85 is moved forward or backward to move the thermostat unit 60 through the unit shaft 80 in the + X axis direction or the -X axis direction.

Accordingly, as the valve 68 of the thermostat unit 60 is moved, the openings of the hot water inlet 11 and the cold water inlet 12 are adjusted to regulate the inflow amounts of the hot water and the cold water.

In short, by rotating the temperature control handle 40, the rotation of the temperature regulating stem 44, the forward or backward movement of the guide 85, the forward or backward movement of the unit shaft 80, And the inflow amount of the hot water and the cold water is adjusted.

At this time, when the temperature is set by using the temperature control handle 40 at, for example, 40 degrees or 50 degrees, the wax filled in the wax element 61 by hot water or cold water flowing into the mixing chamber 13 The piston 61a is contracted or expanded and interlocked therewith and the valve 68 is moved again secondary based on the change in the length S of the piston 61a The opening degree of the cold water inlet 12 is adjusted.

Accordingly, since the inflow amount of the hot water and the cold water or the change amount thereof is automatically adjusted, the temperature of the initially set mixed water can be maintained without change.

Of course, if the setting value is changed, that is, if the desired temperature is set by operating the temperature control handle 40, the temperature may be higher or lower than the initial setting value, and the temperature can be adjusted by this method. The rotation opening / closing plate 33 is not rotated.

Next, we will look at flow control. At this time, the flow adjusting handle 50 is rotated by itself without pressing the flow adjusting handle 50 toward the temperature adjusting handle 40.

Then, since the clutch 70 is disengaged from the flange portion 40a of the temperature control handle 40, only the flow adjustment handle 50 is rotated independently to induce rotation of the rotary switch plate 33, .

That is, when the flow adjusting handle 50 is rotated, the flow adjusting stem 52 is rotated through the flow adjusting handle guide 51 connected to the flow adjusting handle 50, and the unit shaft 80 is rotated in conjunction therewith, One end 62b of the element guide 62 of the thermostat unit 60 is coupled to the receiving portion 81 of the unit shaft 80. When the unit shaft 80 is rotated, (60) is rotated.

When the thermostat unit 60 is rotated, the spring guide 65 connected to the thermostat unit 60 is rotated to rotate the rotary switch plate 33. As a result, The discharge flow rate can be adjusted as well.

As described above, according to the present embodiment, both the temperature and the flow rate can be adjusted so as to be both easy to install and use, and also to reduce the material cost and consequently the manufacturing cost.

Hereinafter, FIG. 7 is a view showing a temperature and flow adjustment handle for a thermostat cartridge of a faucet capable of adjusting the temperature and the flow rate according to another embodiment of the present invention, in which the above-described clutch 70 is structurally excluded .

7, when the flow adjusting handle 50 and the temperature adjusting handle 40 are rotated independently of each other, the flow adjusting stem 52 and the temperature adjusting stem 44 are operated to adjust the flow rate and the temperature individually .

As in the present embodiment, even when the clutch 70 is excluded from the configuration, it is possible to control both the temperature and the flow rate while having a simple and simple structure, and it is possible to reduce the manufacturing cost as well as the ease of use. Lt; / RTI >

The present invention is improved in both temperature and flow control so that it is easy to install and use, and also has the effect of reducing the material cost and consequently the manufacturing cost.

Further, the present invention improves the mixing efficiency of the hot water and the cold water through the improvement of the valve structure, and sensitively increases the operation of the valve, thereby maintaining the uniform mixing temperature.
