For this reason, the sterilized tap water will be supplied and the cleanliness is maintained.

  On the other hand, it is also known that free residual chlorine affects proteins. That is, since chlorine has an oxidizing power, it denatures proteins. For this reason, when hair and skin are washed with tap water having a high residual chlorine concentration, the hair and skin proteins are denatured and are damaged. That is, when the residual residual chlorine comes into contact with the anus and vulva, the exposed anus and vulva where the mucous membrane is weaker than the skin has a considerable influence.

  For example, Patent Document 1 describes a toilet bowl equipped with a local cleaning device that sprays cleaning water from a nozzle outlet toward a human body part, and purifies the cleaning water on the cleaning water supply passage to the nozzle outlet. Even if the washing water ejected from the nozzle enters the anus, the washing water is purified by the water purification device. It is described that there is an effect that it does not cause inconveniences such as entering into the intestines and killing useful bacteria by entering the intestine.

  Further, Patent Document 2 states that “in a local cleaning device that discharges a predetermined amount of water based on a water discharge request and cleans the anus, vulva, and other skin surfaces, the cleaning nozzle and cleaning water are supplied. A water pipe for heating, a heater for heating while passing the washing water, an agent for hemorrhoids, a moisturizing agent, a lubricant, a deodorizing agent, a combination of two or more selected from a fragrance, and the A drug sustained-release cartridge having a hard material container filled with a saturated aqueous solution of drug or a uniform dispersion solution of the drug, an opening formed in the hard material container, and a porous film covering the opening is provided.

  By the way, in Patent Document 1, “a water purification device for purifying cleaning water is provided on the cleaning water supply passage to the nozzle outlet” was not clear by a clear method or structure for replacement of the water purification device. A water purifier purifies water by filtering water with a filter. For this reason, it is necessary to replace the filter periodically because it is clogged or the filter becomes dirty. By the way, water always passes through the inside of the purification device. For this reason, when exchanging the filter, it is necessary to stop the water passing through the purifier at that time, and it is necessary to restart the water passing through the purifier after exchanging the filter. At this time, the water faucet was stopped and replaced, but there was a problem that water leaked from the pipes before and after the purification device unless the water inside the piping before and after the purification device was drained. . In addition, it is not easy for the user of the cleaning device to stop the water tap, drain the water inside the pipe, and replace the entire purification device every time the purification device is replaced.

  Further, in Patent Document 2, “the drug sustained-release cartridge is attached to the outside of the water distribution pipe, and the vicinity of the opening of the drug sustained-release cartridge is inserted into the water distribution pipe and can be replaced. Since it is much easier to replace the sustained-release cartridge, the cartridge in the sustained-release cartridge decreases and can be easily replaced even if it disappears. Although the released functional water can be used, it is very convenient. "However, the specific configuration of the drug sustained-release cartridge is not disclosed. Further, “the drug sustained release cartridge 7 is formed of a relatively inexpensive material such as acrylic or ABS (acrylonitrile butadiene styrene) resin that does not deform even when external pressure is applied, but as shown in FIG. A part of the main body 4 protrudes from the main body 4 so that the user can freely attach and detach. ”However, a specific configuration is not disclosed.

  Therefore, an object of the present invention is a local cleaning device using a chlorine residual filter, in which water passes only when the filter is installed, and the passage of water stops when the filter is removed such as when the filter is replaced. Accordingly, an object of the present invention is to provide a local cleaning device, a toilet bowl with a local cleaning device, and a switching valve for the local cleaning device in which the filter for the local cleaning device can be easily replaced.

  In order to solve the above-described problems, a local cleaning device according to the present invention is a local cleaning device that ejects cleaning water from a cleaning nozzle provided in a cleaning unit toward a human body local part, and chlorine is provided between the cleaning unit and a water supply pipe. A chlorine removal housing into which the removal filter is inserted and a switching valve that opens when the chlorine removal housing is mounted are provided.

  By applying the local cleaning device, the toilet bowl with the local cleaning device and the filter for the local cleaning device according to the present invention, the local cleaning device using the residual filter, water passes only when the filter is installed. When the filter is removed, such as when replacing the filter, the passage of water is stopped, so that the filter for the local cleaning device can be easily replaced.

The pipe 36 is connected to the local cleaning device 2 and supplies purified water to the local cleaning device 2.

FIG. 2 shows a water circuit of the local cleaning device 2 in the first embodiment of the present invention. First, a water supply pipe 22 that is a water source is connected to a switching valve 32 of a water purifier 30 through a branch faucet 24 and a water intake 26 through a pipe 28. The switching valve 32 and the filter 34 are interlocked. When the filter 34 is connected to the switching valve 32, the switching valve 32 and the filter 34 communicate with each other so that water in the pipe 28 is supplied into the filter 34. When the filter 34 is removed from the switching valve 32, the switching valve 32 is The water from the pipe 28 is closed and is not discharged from the switching valve 32. The filter 34 is connected to a water intake port 38 of the local cleaning device 2 via a pipe 36. The water intake 38 is connected to the water stop valve 42 via the check valve 40. The water stop valve 42 is connected to a hot water heater 46 via a water amount detector 44. A flow path switching valve 50 is connected to the downstream side of the hot water heater 46 via a water-driven pump 48, and a foreign substance remover 52 and a nozzle 54 are provided at the tip of the flow path switching valve 50. By configuring in this way, purified water flows to the nozzle 54 only when the filter 34 is connected, and when the filter 34 is not connected, the water supply stops at the switching valve 32.
Example 1

  The configuration of the switching valve 32 and the filter 34 will be described in detail with reference to FIG. FIG. 3 shows a state where the switching valve 32 and the filter 34 are connected.

  The filter 34 (chlorine removing housing) is a cylindrical filter lower part 62 in which the filter material 60 is built, a cylindrical filter step part 64 mounted on the filter lower part 62 and having a radius smaller than the radius of the filter lower part 62, Further, the filter top portion 66 is mounted on the filter step portion 64 and has a smaller radius. An opening 70 of a filter water inlet 68 that communicates with the filter material 60 opens at the top surface of the filter top 66. A groove is formed in the filter top side surface 72, which is the side surface of the filter top 66, and an O-ring 74 is fitted therein. On the filter top side surface 72, below the O-ring 74, an opening 78 of a filter outlet channel 76 that communicates with the other of the filter material 60 opens. A filter step 64 is provided around the filter top side surface 72. Two steps of grooves are provided in the side surface 72 of the filter step portion which is the side surface of the filter step portion 64, and O-rings 80 and 82 are provided respectively. A locking protrusion 84 is provided below the filter step portion side surface 72 and the O-ring. Here, the filter material 60 is a material for removing free residual chlorine from tap water, and resin, powder, fiber, and the like are used, and a necessary material is appropriately selected according to cost and removal concentration.

  The switching valve 32 has a switching valve function unit that switches whether tap water is introduced into the filter 34 or stopped, and a cap function unit that covers the filter 34.

  The switching valve function unit includes a water inlet 96 connected to the water supply side pipe 28, a piston 98, a spring 100, a stopper 102, and a water outlet 104.

  On the other hand, the cap function portion includes a filter lower portion receiving portion 106 corresponding to the filter lower portion 62, a filter step portion receiving portion 108 corresponding to the filter step portion 64, a filter top portion receiving portion 110 corresponding to the filter top portion 66, It is comprised from the recessed part 111 for latching provided corresponding to the processus | protrusion 84. FIG.

  In the above configuration, a valve open state in which the switching valve 32 and the filter 34 are connected as shown in FIG. 3 and a valve closed state in which the switching valve 32 and the filter 34 (not shown) are separated will be described.

  First, in the valve open state, the switching valve 32 and the filter 34 are connected to each other. The spring chamber 112 is provided inside the water inlet 96 and the spring 100 is provided, and is pressed from the piston 98 to be shortened. It is in the state. The piston 98 includes a circular piston head 114 and a piston rod 116 that projects vertically below the piston head 114. A piston head opening 118 that opens the water inlet 96 and the filter top receiving portion 110 in communication with the back of the water inlet 96 on the vertical lower side of the spring chamber 112 is opened. The piston head opening 118 is in an open state because the piston head 114 moves vertically upward of the spring chamber 112 while pressing the spring in the valve open state. The piston rod 116 is provided with a stopper 102 below the piston head opening 118, passes through the piston rod opening 120 opened in the stopper 102, and comes into contact with the top surface of the filter top 66. That is, when the filter top 66 is inserted vertically downward, the piston rod 116 is pushed up. As a result, the piston head 114 is pushed up, and the piston head opening 118 is opened.

At this time, since the piston head opening 118 is opened, the water inlet 96 communicates with the opening 70 and the filter water inlet 68 through the piston head opening 118 and the piston rod opening 120. Further, the filter water channel 76 and the opening 78 communicate with the water outlet 104. As a result, all the passages can pass water. In this case, since water in which free residual chlorine is reduced from tap water can be ejected from the nozzle 54, the contact of free residual chlorine with the anus or vulva can be reduced.
At this time, the locking projection 84 is locked to the locking recess 111 so that the filter 34 and the switching valve 32 are not separated.

On the other hand, the valve closed state will be described. When the filter 34 is separated from the switching valve 32, the filter top portion 66 is separated from the filter top receiving portion 110, so that the piston head 114 is moved downward by being pressed by the spring 100. Therefore, the piston head opening 118 is closed, and the water inlet 96 and the filter water inlet 68 do not communicate with each other. For this reason, water flow is stopped. That is, when the filter 34 is replaced, water supply from the water supply pipe 22 is stopped by the switching valve 32, so that the filter 34 can be replaced without closing the branch tap 24.

  Example 2 will be described with reference to FIGS.

  FIG. 4 shows a second embodiment of the local cleaning device 2 according to the present invention, and shows a side view. The major difference from the first embodiment is largely different from FIG. 1 in that the water purifier 128, that is, the switching valve 130 and the filter 132 are built in the local cleaning device 2. In FIG. 4, only the switching valve 130 and the filter 132 are depicted on the appearance.

  FIG. 5 shows a water circuit of the local cleaning device 2 in the second embodiment of the present invention. The difference from FIG. 2 is that the switching valve 130 and the filter 132 are provided between the check valve 126 and the water stop valve 42. The pipe 122 is connected to the water intake 124. The water intake 124 is connected to the check valve 126. By adopting the configuration of the second embodiment, it is possible to achieve integration with the local cleaning device 2 and it is possible to incorporate the filter 132 in terms of design.
