The contents of the above applications are all incorporated by reference as if fully set forth herein in their entirety. 
     TECHNICAL FIELD 
     The present invention relates to a water saving toilet that flushes the toilet using a dramatically small amount of flushing water, and more particularly, to a water saving toilet that increases a water pressure of flushing water to be discharged to the toilet by inserting a pressing tube into a cistern and that installs a straight discharge pipe to be automatically opened and closed by a water pressure of flushing water, a permanent magnet, and an electromagnet in a discharge port of the toilet and in which an odor removing unit that sucks and discharges an odor is installed and that thus smoothly discharges excreta, as the straight discharge pipe is automatically opened and closed by a water pressure of flushing water, a permanent magnet, and an electromagnet while cleanly flushing the toilet with a small quantity of flushing water by increasing a water pressure of flushing water discharged from the cistern to the toilet and that blocks an odor rising from a foul-water port to the toilet with a small quantity of flushing water housed within the toilet and in which a user can freshly use the toilet without a unpleasant feeling, as the odor removing unit sucks an odor generating when the user uses the toilet with a fan and discharges the odor to the foul-water port. 
     BACKGROUND ART 
     In general, 40% of countries on the earth including South Korea has been known to as a water shortage country, and recently, water resource exhaustion has been deepened due to a water shortage phenomenon and thus each country has actively advised to save water to citizens and therefore, a recognition of citizens on water saving has increased and thus various kinds of methods that can save water have been suggested in various forms. 
     When a person uses a toilet or a washbowl provided in a bathroom, much water is used and thus there is a problem that a great quantity of water is unnecessarily wasted, and particularly, in order to discharge sewage such as excreta and urine, the toilet uses much water of about 8-13 l at one time. Therefore, in order to reduce water consumption, in a normal home, a method of putting a brick or a pet bottle within a cistern of the toilet is used. 
     However, in such a method, because an amount of water decreases by a volume of a brick put within the cistern of the toilet, a water pressure of water discharged from the cistern into the toilet is lowered and thus there is a problem that excreta is not cleanly flushed in the toilet and thus the method is no fundamental countermeasure. 
     Therefore, in Korean Patent No. 10-0509069 (toilet having a variable siphon pipe), a flush toilet in which a variable siphon method and a natural discharge method are mixed by applying a variable siphon pipe to the toilet was suggested, but in the flush toilet, excreta is not smoothly discharged due to an erroneous operation, a blocking phenomenon of a discharge pipe occurs, and parts are easily worn out and thus there is a problem that the flush toilet is not actually produced as a product. 
     Further, because the toilet is mostly installed in a relatively narrow and closed space like a bathroom, when a user uses the toilet, a serious odor occurs, and the user feels an unpleasant feeling due to such an odor and a next user feels a serious unpleasant feeling. 
     Nowadays, in order to remove such an odor, a method of compulsorily discharging an odor by installing a ventilator at a wall or a ceiling or a method of inhaling an odor and liquefying and removing an ammonia gas, which is a cause material of an odor in water has been suggested, but the method is not economical and an effect thereof fell short of expectations. 
     Therefore, at a time point in which toilet culture improvement effort to improve an internal environment of a dirty and unpleasant bathroom is executed, necessity to effectively remove an odor or other unpleasant smell within the bathroom is further requested.

     BEST MODES FOR CARRYING OUT THE INVENTION 
     In an exemplary embodiment of the present invention, by increasing a water pressure of flushing water discharged from a cistern to a toilet, a toilet is cleanly flushed with a small amount of flushing water, excreta is smoothly discharged from the toilet, while an odor rising from a foul-water port to the toilet is blocked, and when a user uses the toilet, in order for a user to prevent from feeling a unpleasant feeling due to an odor generating in excreta, by inhaling an odor and discharging the odor to the foul-water port, fresh and comfortable bathroom space can be provided. 
     Hereinafter, a main configuration of a water saving toilet according to an exemplary embodiment of the present invention will be described with reference to the accompanying drawings. The water saving toilet includes a cistern  10  in which a discharge valve  14  that opens and closes a drain port  12  is installed and in which a water supply valve  15   a  and a water supply lever  15   b  that open and close a water pipe  15  are installed and in which a button that operates the discharge valve  14  is installed; a pressing tube  20  inserted into the cistern  10  to be connected to the water supply lever  15   b  of the water supply valve  15   a  with a rope  22  while housing flushing water; a toilet body  30  in which a plurality of discharge holes  32   a  are formed in a circumference of the lower end of a drain  31   b  and in which an exhaust port  40   a  is formed in a lower portion of the rear end thereof while forming a channel  31   a  and the drain  31   b  that discharge flushing water through the drain port  12  of the cistern  10 ; a straight discharge pipe  40  coupled to the exhaust port  40   a  of the toilet body  30  and in which an opening and closing port  41  to be automatically opened and closed by a water pressure of flushing water and a permanent magnet  43  is installed to discharge flushing water and excreta from the toilet body  30 ; a discharge box  50  installed at the rear end of the straight discharge pipe  40  and that discharges excreta to a foul-water port, as a lower portion thereof is coupled to the foul-water port while an electromagnet  51  is installed at a side surface of one side of the inside thereof; and an odor removing unit  60  in which a suction pipe  60   a  is connected to the toilet body  30  and the discharge box  50  and that sucks an odor generating in excreta and that discharges the odor to the discharge box  50  to remove the odor. 
     In the present exemplary embodiment, the straight discharge pipe  40  to be automatically opened and closed by a water pressure of flushing water, a permanent magnet, and an electromagnet is installed at the rear end of the toilet body  30  while increasing a water pressure of flushing water discharged to the toilet body  30  by inserting the pressing tube  20  into the cistern  10 , and the odor removing unit  60  that sucks and removes an odor generating in excreta is formed. 
     In a main configuration of the present exemplary embodiment, as shown in  FIGS. 1 to 6 , the cistern  10  is disposed at an upper portion of the rear side of the toilet body  30  to be described later, the cistern  10  is enclosed with a cover  11  at the outside thereof, the drain port  12 , a valve holder  13 , and the discharge valve  14  that discharge flushing water (tap water) to the toilet body  30  are formed in a lower portion thereof and the water pipe  15 , the water supply valve  15   a , and the water supply lever  15   b  that supply flushing water are installed at one side thereof. 
     At one side of an upper portion of the cover  11 , the button  16 , a lever  16   a , and a spring  16   b  that open and close the discharge valve  14  are installed, and a link  17  that vertically rotates by the lever  16   a  is installed in an upper portion of the inside of the cistern  10 , and a rope  18  is connected to an end portion of one side of the link  17  and an upper portion of the discharge valve  14 . 
     At the cover  11 , a detection sensor  19  is attached to the front side, which is location direction of a user, a proximity sensor, a temperature sensor, and a motion sensor may be applied to the detection sensor  19 , and it is necessary that the detection sensor  19  detects a user. 
     Therefore, in the cistern  10 , flushing water is supplied to internal space through the water pipe  15  and the water supply valve  15   a , and after the user uses the toilet, when the user presses the button  16 , the link  17  pulls the rope  18  upward by rotating, and thus the discharge valve  14  receives guidance of the valve holder  13  to operate to an upper portion and thus discharges flushing water to the toilet body  30  by opening the drain port  12 . 
     Further, in a main configuration of the present exemplary embodiment, the pressing tube  20  performs a function of raising a water pressure of flushing water discharged from the cistern  10  to the toilet body  30 , and as shown in  FIGS. 2 to 6 , the pressing tube  20  has internal space to float on a surface of flushing water housed within the cistern  10 , a plurality (2 to 5) of inlet and outlet holes  21  are formed in a lower portion thereof to inject flushing water into internal space, and the rope  18  connected to the discharge valve  14  and the link  17  penetrates a central portion. 
     The pressing tube  20  may be produced in a shape of a cylinder or a rectangular parallelepiped according to a shape of internal space of the cistern  10 , and it is necessary to vertically move the pressing tube  20  while close contacting with an inner side surface of the cistern  10 , and in a state in which flushing water is housed at internal space by injection molding with plastic having a light weight, the pressing tube  20  floats on a surface of flushing water housed within the cistern  10 , and a rope  22  is connected to a central portion of a lower portion and the water supply lever  15   b  of the water supply valve  15   a.    
     Therefore, when flushing water is supplied into the cistern  10  through the water pipe  15  and the water supply valve  15   a , flushing water is housed into internal space through a plurality of inlet and outlets hole  21  in a state in which the pressing tube  20  is floated on a surface of flushing water due to a light weight, and in this state, after a user uses the toilet, when flushing water is discharged from the cistern  10  to the toilet body  30  by pressing the button  16 , a self-load of the pressing tube  20  and a load of flushing water housed at internal space are applied to flushing water housed in the cistern  10  and thus a water pressure of flushing water discharged to the toilet body  30  increases. 
     That is, when flushing water is discharged from the cistern  10  to the toilet body  30 , a self-load of the pressing tube  20  and a load of flushing water housed at internal space of the pressing tube  20  operate at a surface of flushing water housed in the cistern  10  and thus a water pressure of flushing water discharged to the toilet body  30  increases. 
     Further, when flushing water is supplied into the cistern  10  through the water pipe  15  and the water supply valve  15   a , the pressing tube  20  pulls the rope  22  while moving upward in a state floated on a surface of flushing water, and when an appropriate amount of flushing water is housed in the cistern  10 , the water supply lever  15   b  of the water supply valve  15   a  rotates by pulling by the rope  22  and thus the water supply valve  15   a  is closed to prevent flushing water from supplying. 
     Further, in a main configuration of the present exemplary embodiment, as shown in  FIGS. 1 to 5 , the toilet body  30  is formed with an upper assembly  31 , an intermediate assembly  32 , and a lower assembly  33 , and the drain port  12  of the cistern  10  is inserted into an upper portion of the rear side of the upper assembly  31  and is coupled thereto, and as the upper assembly  31  and the intermediate assembly  32  are coupled, while the channel  31   a  and the drain  31   b  that discharge flushing water are formed, a plurality of discharge holes  32   a  are formed in the intermediate assembly  32  to locate at a periphery of the lower end of the drain  31   b.    
     The toilet body  30  may be produced by injection molding each of the upper assembly  31 , the intermediate assembly  32 , and the lower assembly  33  with plastic, and in this case, the toilet body  30  can be simply produced, have a light weight, have excellent workability, and be easily carried. 
     Therefore, when flushing water is discharged through the drain port  12  of the cistern  10 , flushing water is discharged to a plurality of discharge holes  32   a  through the channel  31   a  and the drain  31   b  formed between the upper assembly  31  and the intermediate assembly  32  and thus flushing water can cleanly flush the toilet body  30  and excreta. 
     Further, in a main configuration of the present exemplary embodiment, while the straight discharge pipe  40  smoothly discharges excreta and flushing water from the toilet body  30 , the straight discharge pipe  40  performs a function of blocking an odor rising from a foul-water port, and as shown in  FIGS. 2 to 5  and  FIG. 7 , a discharge port  40   a  of the straight discharge pipe  40  instead of a conventional S-shaped siphon pipe is formed in a lower portion of the rear end of the lower assembly  33  in the toilet body  30 , the straight discharge pipe  40  is inserted into the discharge port  40   a  and is coupled thereto, and it is preferable that the straight discharge pipe  40  is formed in a cylindrical shape, and by installing an end portion thereof to be inclined downward, excreta and flushing water may be easily discharged. 
     In an end portion of the straight discharge pipe  40 , the opening and closing port  41  to be automatically opened and closed by a water pressure of flushing water and the permanent magnet  43  is installed, and the opening and closing port  41  is installed to rotate by a hinge at the upper end of an end portion of the straight discharge pipe  40 , packing  42  is attached to the front side that close contacts with the end portion of the straight discharge pipe  40 , and in a lower portion of the rear side thereof, an iron piece  41   a  is attached and may be replaced with a permanent magnet. 
     In the straight discharge pipe  40 , the permanent magnet  43  is installed at a location opposite to the opening and closing port  41  installed in an end portion thereof, the permanent magnet  43  performs a closing function by close contacting the opening and closing port  41  in an end portion of the straight discharge pipe  40  by pulling the iron piece  41   a  installed in the opening and closing port  41  by a magnetic force, and the permanent magnet  43  is mounted in a rotation shaft  51   a  of the electromagnet  51  to be installed at a location opposite to the iron piece  41   a  of the opening and closing port  41 . 
     The electromagnet  51  operates by a switch  52  turned on/off by operation of the button  16  installed in the cover  11  of the cistern  10 , and when a user presses the button  16 , while the switch  52  is turned on, a magnetic force occurs by supplying power from the controller, and thus by separating the permanent magnet  43  from the iron piece  41   a  by pulling the rotation shaft  51   a  and the permanent magnet  43 , a magnetic force of the permanent magnet  43  applied to the iron piece  41   a  is released, and thus after the opening and closing port  41  of the straight discharge pipe  40  opens by a water pressure, when an appropriate time (3-5 seconds) has elapsed, after excreta and flushing water are discharged from the toilet, by blocking power from the controller, when a magnetic force of the electromagnet  51  is disappeared, the permanent magnet  43  is returned to an original location by elasticity of a spring  51   b  mounted in the rotation shaft  51   a  and thus as a magnetic force of the permanent magnet  43  is applied again to the iron piece  41   a , the straight discharge pipe  40  closes the opening and closing port  41  to be sealed. 
     Therefore, in the straight discharge pipe  40 , as the opening and closing port  41  is automatically opened and closed by a water pressure of flushing water, the permanent magnet  43 , and the electromagnet  51 , excreta and flushing water are smoothly discharged from the toilet body  30 , and an odor rising from a foul-water port is effectively blocked. 
     Further, in a main configuration of the present exemplary embodiment, as shown in  FIGS. 2 to 5  and  FIG. 7 , the discharge box  50  is installed to seal by enclosing an end portion of the straight discharge pipe  40 , and a cover  50   a  is put in an upper portion thereof, and in the cover  50   a , a fan  61  and a discharge pipe  63  of the odor removing unit  60  in which an upper portion and a lower portion are installed to communicate are installed, and at a side surface of one side of the inside thereof, the opening and closing port  41 , the permanent magnet  43 , and the electromagnet  51  of the straight discharge pipe  40  are installed, and a lower portion thereof is coupled to the foul-water port and thus excreta and flushing water discharged through the straight discharge pipe  40  are discharged to the foul-water port. 
     At a side surface of one side of the inside of the discharge box  50 , the rotation shaft  51   a  and the electromagnet  51  in which the permanent magnet  43  is mounted are attached, the electromagnet  51  and the permanent magnet  43  are installed to correspond to the iron piece  41   a  at a location opposite to a rotation direction of the opening and closing port  41  installed in the straight discharge pipe  40 , when the permanent magnet  43  is separated by a predetermined distance from the iron piece  41   a  by pulling the permanent magnet  43  mounted in the rotation shaft  51   a  by a magnetic force of the electromagnet  51 , a magnetic force of the permanent magnet  43  applied to the iron piece  41   a  is lost and thus the opening and closing port  41  is opened in the straight discharge pipe  40  by a water pressure. 
     The electromagnet  51  is operated by the switch  52  turned on/off by operation of the button  16  installed in the cover  11  of the cistern  10 , and when a user presses the button  16 , while the switch  52  is turned on, power is supplied from the controller to the electromagnet  51  and thus a magnetic force generates. 
     When the user presses the button  16 , while flushing water housed in the cistern  10  is discharged to the toilet body  30 , when the opening and closing port  41  installed in an end portion of the straight discharge pipe is opened by a water pressure and when excreta and flushing water are discharged, after the electromagnet  51  maintains the opening and closing port  41  in an open state for an appropriate time (3-5 seconds) by separating the iron piece  41   a  and the permanent magnet  43  by pulling the permanent magnet  43  by a magnetic force, as power is blocked, when a magnetic force is lost, the permanent magnet  43  is returned to an original location by the spring  51   b  and thus the opening and closing port  41  closes and seals the straight discharge pipe  40  and thus after excreta and flushing water are discharged from the toilet body  30 , an appropriate amount of remaining water is provided to the bottom of the inside of the toilet body  30 . 
     Further, in a main configuration of the present exemplary embodiment, as shown in  FIGS. 2 to 5  and  FIGS. 8 and 9 , the odor removing unit  60  includes a suction pipe  60   a  connected to communicate with the toilet body  30  and the discharge box  50 , a fan  61  installed in the suction pipe  60   a  and that sucks and discharges an odor by driving of a motor  62 , and a discharge pipe  63  connected to the suction pipe  60   a  to be located at internal space of the discharge box  50  and in which a cover  64  to be opened and closed by a wind pressure is installed. 
     The suction pipe  60   a  is connected to the inside of the rear side of the lower assembly  33  and a side surface of one side of the discharge box  50  in the toilet body  30 , and at one side of the suction pipe  60   a , the fan  61  that operates by driving of the motor  62  is installed to suck an odor at the inside of the lower assembly  33  and to discharge an odor to internal space of the discharge box  50 . 
     The discharge pipe  63  connected to the suction pipe  60   a  is located at internal space of the discharge box  50 , and the cover  64  is installed to rotate by a hinge in an upper portion of the rear end of the discharge pipe  63  and thus when a wind pressure operates by operation of the fan  61 , at the rear end of the discharge pipe  63 , the cover  64  is opened, and as the fan  61  is stopped, when a wind pressure is lost, the cover  64  closes the rear end of the discharge pipe  63  by a self-load. 
     Therefore, in the odor removing unit  60 , when the detection sensor  19  detects a user, the controller drives the motor  62  and thus the fan  61  rotates and the suction pipe  60   a  thus sucks an odor in generating in excreta and the odor is removed by discharging to the foul-water port through the discharge pipe  63  and the discharge box  50 , and as the user is not detected, when the fan  61  is stopped, the cover  64  closes the discharge pipe  63  and thus discharge of an odor to the outside is blocked. 
     In an exemplary embodiment of the present invention, as a pressing tube is installed in a cistern, a water pressure of flushing water discharged from the cistern to a toilet body is increased, and by applying a straight discharge pipe structure instead of a conventional S-shaped siphon pipe using much flushing water, a use amount of flushing water is reduced and thus the toilet can be cleanly flushed with a very small amount of flushing water and thus waste of water can be reduced, and when the toilet body is divided into a upper assembly, an intermediate assembly, and a lower assembly and is made of a plastic material by injection molding, the toilet can be simply produced, have a light weight, have an excellent workability, and be easily carried. 
     Further, in an exemplary embodiment of the present invention, because a straight discharge pipe to be automatically opened and closed by a water pressure, a permanent magnet, and an electromagnet is installed at the rear end of a toilet body, excreta and flushing water are smoothly discharged from the toilet body, and by providing an appropriate amount of remaining flushing water within the toilet, while an odor rising from the foul-water port to the toilet is blocked, and by blocking sewage from being attached to an internal surface of the toilet, a flushing effect is enhanced. 
     Further, in an exemplary embodiment of the present invention, as an odor removing unit is installed, the odor removing unit sucks an odor generating in excreta and discharges the odor to the foul-water port and thus the user can use a toilet with a fresh feeling without feeling an unpleasant feeling. 
     Although exemplary embodiments of the present invention have been described in detail hereinabove, it should be clearly understood that many variations and modifications of the basic inventive concepts herein taught which may appear to those skilled in the present art will still fall within the spirit and scope of the present invention, as defined in the appended claims.
