BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a flush toilet equipped with a deodorizing apparatus, and more particularly, it relates to a flush toilet and a deodorizing method of the flush toilet capable of cleaning and sterilizing a toilet bowl. [0003] 2. Description of the Related Art [0004] To remove an odor during use of a flush toilet, it may be insufficient to merely flush it away after use, and various deodorizing apparatuses have heretofore been proposed to deodorize the flush toilet. [0005] Japanese Patent Publication Laid-open No. 3-286052 discloses a deodorizing apparatus wherein after an odor in a toilet bowl is sucked in by an operation of a ventilator, the odor is blown to a water containing member supplied with water in order to dissolve an offensive odor components in the water in the water containing member, and then it is discharged to sewage through drain pipes. However, this deodorizing apparatus has problems that it is necessary to provide the drain pipe in an intermediate part between a discharge part of the bowl and the sewage and it is not easy to install the drain pipe in an existing bowl, and that because the water containing member contains water, a pressure loss is caused by the water containing member when the offensive odor components are sucked in. [0006] Furthermore, Japanese Patent Publication Laid-open No. 2000-129747 discloses that sterile water is supplied to a filter having moisture retention properties, and the odor in the bowl is sucked in via this filter to adsorb and decompose the offensive odor components by the sterile water, and then new sterile water is supplied to the filter to clean the filter, and the bowl is also sterilized by this sterile water. However, such a method of supplying the sterile water to the filter has a problem that the sterile water might deteriorate the filter, and that the wet filter causes a great pressure loss to increase load in the suction of the offensive odor components. SUMMARY OF THE INVENTION [0007] It is an object of the present invention to provide a flush toilet equipped with a deodorizing apparatus and a deodorizing method of the flush toilet which effectively remove a source of an offensive odor in the flush toilet and which can decompose the odor and also clean and sterilize a toilet bowl. [0008] A flush toilet of the present invention is equipped with a bowl and flushing means for flushing an inside of the bowl, and the flush toilet comprises: an electrolytic cell fitted with a pair of electrodes and storing water; a power source to electrify the pair of electrodes; odor suction means for sucking in an odor of excrement; and odor supply means for supplying the odor sucked in by the odor suction means into the electrolytic cell, wherein the electrodes are electrified by the power source to generate electrolytic water in the electrolytic cell, and the odor is removed by the electrolytic water. [0009] The flush toilet defined in claim 2 according to the invention of claim 1 further comprises: an adsorption member which adsorbs the odor sucked in by the odor suction means; and heating means for heating the adsorption member to release the odor adsorbed by the adsorption member, wherein the odor released from the adsorption member is supplied into the electrolytic cell by the odor supply means to remove the odor. [0010] In the flush toilet defined in claim 3 according to the invention of claim 1 or 2, the odor supply means supplies the odor into the electrolytic cell from a position lower than a half of a height of the electrolytic cell. [0011] In the flush toilet defined in claim 4 according to the invention of claims 1 to 3, the odor is supplied into the electrolytic cell by the odor supply means in a state where the electrolytic water is stored in the electrolytic cell. [0012] The flush toilet defined in claim 5 according to the invention of claims 1 to 4 comprises: a flow path to flow the water or the electrolytic water in the electrolytic cell into the bowl; and a valve which is provided in the flow path and which controls whether or not to allow the water or the electrolytic water to be flown into the bowl. [0013] In the flush toilet defined in claim 6 according to the invention of claim 5, the flushing means comprises a flush lever or switch to flow water into the bowl, and the valve is opened in conjunction with the lever or switch. [0014] The flush toilet defined in claim 7 according to the invention of claim 5 or 6 further comprises: detection means for detecting that the bowl is in use, and when the detection means detects that the bowl is in use, the valve is opened for a predetermined period every predetermined time. [0015] The flush toilet defined in claim 8 according to the invention of claims 5 to 7 comprises a manual switch to open the valve for the predetermined period. [0016] In a deodorizing method of a flush toilet of the present invention to implement deodorization in such a manner that an odor of excrement is supplied into an electrolytic cell which stores water and which includes a pair of electrodes provided so that at least part of the pair of electrodes is immersed in the water, and the method comprises electrifying the pair of electrodes before and/or during and/or after the supply of the odor into the electrolytic cell to generate electrolytic water in the electrolytic cell, and decomposing odor components contained in the odor by the electrolytic water. [0017] In the deodorizing method of the flush toilet defined in claim 10 according to the invention of claim 9, the electrolytic water is flown into a bowl to clean, sterilize and deodorize the bowl. [0018] According to the present invention, a source of an offensive odor in a flush toilet can be removed, and the odor can be decomposed. Moreover, according to the present invention, the bowl of the flush toilet can be cleaned and sterilized.
