Patent Application
20110036430
The present invention relates to a cartridge which comprises separate temperature and flow adjusting shafts whereby temperature and flow adjustments can be controlled independently from each other and where, if desired, flow and temperature cartridges can be used separately.
Currently, there are various mechanisms which can perform temperature and flow control. Some of these mechanisms only control the temperature, some only control the flow and some others can control both temperature and flow.
In the Korean patent application No. KR20050018770, operating mechanism of the system is disclosed and it is stated that first of all hot and cold water are mixed and temperature adjusting is made, and then the flow adjusting is performed. These adjustments are performed by means of fixed and movable discs.
The U.S. Pat. No. 5,845,674 mentions about adjustability of temperature and flow independently from each other. The same application indicates both a flow control element and a temperature control element. The same application discloses a disk in the cartridge for adjusting the temperature.
The Turkish patent application No. TR200704329 discloses a cartridge wherein the temperature and the flow control shafts can be controlled separately.
Upon reviewing the above mentioned patent documents, it is seen that cartridges which can perform temperature and flow adjustment independently from or dependent on each other are present in the state of the art. However, the said cartridges have an integral nature and the cartridge which performs temperature adjustment or flow adjustment on demand can not be separated from the integral structure to be mounted to another mechanism.
The objective of the present invention is to ensure, during use of a faucet, that the temperature adjustment is performed once and subsequently the faucet is turned on/off only by flow control. By means of first performing temperature adjustment of the water in accordance with its direction of arrival and in the second stage carrying out flow control continuing in the flow direction of the water, temperature of the water is fixed and saving is obtained in energy, water and time together with ease in use.
Another objective of the invention is to realize a cartridge in which the temperature adjustment mechanism and the flow adjustment mechanism are formed by independent mechanisms that can be separated from each other.
The cartridge realized to fulfill the objectives of the present invention is illustrated in the accompanying figures, in which;
The components shown in the figures are numbered as follows:
The cartridge (1) comprises a lower cap (2) which is provided at the bottom and enables hot and cold water to enter into the cartridge (1) together,
at least one temperature adjusting cartridge (3) wherein temperature adjustment of the hot and cold mixed water entering into the cartridge (1) from the lower cap (2) is performed,
at least one flow adjusting cartridge (4) wherein flow adjustment of the temperature adjusted mixed water is performed,
at least one upper cap (5) through which the temperature and flow adjusted water exits from the cartridge.
In the inventive cartridge (1), the lower cap (2), through which the water enters and on which there are arranged the temperature and flow adjusting elements, comprises channels (21) and legs (22) to facilitate mounting of the said elements.
In the inventive cartridge (1), the temperature adjusting cartridge (3) comprises a temperature adjusting shaft (30) which performs temperature adjustment with its right/left movement, a temperature adjusting element (31) by which precise temperature adjustment is performed, a fixed ceramic disk (32) which is the first location that the water entering from the lower cap (2) arrives, a movable ceramic disk (33) where the incoming hot and cold water mix, at least one gasket (34) located in between the fixed ceramic disk (32) and the movable ceramic disk (33) providing sealing.
In the inventive cartridge (1), the flow adjusting cartridge (4) comprises a flow adjusting shaft (40) which performs flow adjustment with its right/left movement, a flow adjusting element (41) by which precise flow adjustment is performed, a fixed ceramic disk (42) which is the first location that the temperature adjusted water coming from the temperature adjusting cartridge (3) arrives, a movable ceramic disk (43) which adjusts by its rotational movement how much water should exit from the cartridge (1).
In the inventive cartridge (1), the upper cap (5), through which the temperature and flow adjusted water exits the cartridge (1), comprises at least one Teflon seal (51) which serves as a bearing for the flow adjusting element (41), minimizes friction and conveys the pressing force coming from the press nut to the sealing members whereby produces the force that will provide sealing at the said elements; at least one o-ring (52) which provides sealing during use of the cartridge; and channels (53) which enable connection to the other elements located in the cartridge.
In the inventive cartridge (1), the temperature adjusting element (31) comprises at least one Teflon seal (311) thereon which in addition to serving as a bearing for the rotation movement of the temperature adjusting shaft (30) it also reduces friction, legs (312) which enable connection of the said temperature adjusting element (31) to the other elements, at least one o-ring (313) which provides sealing within the temperature adjusting element (31), and at least one fastening hole (314) into which the temperature adjusting shaft (30) is arranged.
In the inventive cartridge (1), the fixed ceramic disk (32) responsible for temperature adjustment comprises at least one channel (321) which enables connection thereof to the other elements and at least one form hole (322) which is required during the process of temperature adjustment. The movable ceramic disk (33) comprises at least one channel (331) which enables connection thereof to the other elements and a form hole (332) thereon for performing temperature adjustment. By fastening of the legs (312) provided on the temperature adjusting element (31), to the channels (321) on the movable ceramic disc (33) in an axial direction, the rotation force coming from the temperature adjusting shaft (30) is conveyed to the movable ceramic disc (33). The fixed ceramic disk (32) is secured by engagement of the legs (22) on the lower cap (2) to the channels (321) provided on the disk. Upon positioning of the form hole (332) on the movable ceramic disc (33) and the form hole (332) on the fixed ceramic disc (32) with the right/left rotation movement of the movable ceramic disc (12), the mixture with the desired temperature is obtained.
In the inventive cartridge (1), there are provided legs (411) on the flow adjusting element (41) connecting the said element to the other members, at least one o-ring (412) providing sealing, and at least one fastening hole (413) into which the flow adjusting shaft (40) is arranged.
In the inventive cartridge (1), the fixed ceramic disk (32) is fixed to the body by engagement of the legs (22) on the lower cap (2) to the channels (321) on the fixed ceramic disk (32) in an axial direction and by engagement of the tabs (35) on the body to the channels (21) on the lower cap (2). The legs (411) located on the flow adjusting element (41) are fastened to the channels (431) provided on the movable ceramic disk (43). This way, the flow adjusting shaft (40) and the movable ceramic disk (43), and the flow adjusting element (41) are rotated together. By aligning the form hole (432) on the flow movable ceramic disc (43) with the form hole (422) on the fixed ceramic disc (42) by means of the rotation movement, flow adjustment and opening and closing control are provided.
In the inventive cartridge (1), the temperature adjusting cartridge (3) and the flow adjusting cartridge (4) are mounted to each other by means of the tabs (35) which are located on the temperature adjusting cartridge (3) and fit into the slots (45) provided on the flow adjusting cartridge (4), and by legs (44) which are located on the flow adjusting cartridge (4) and fit into the channels (36) provided on the temperature adjusting cartridge (3). Thus, the temperature adjusting cartridge (3) and the flow adjusting cartridge (4) can be separated on demand, and can function in independent mechanisms.
It is possible to develop various embodiments of the inventive cartridge (1) within the scope of this fundamental concept. The invention can not be limited to the examples described herein; it is essentially according to the claims.
