The movable lever engaging portion 112 is formed in a wall shape that closes the groove 113 of the movable lever main body portion 111. The movable lever engaging portion 112 is formed with a slit 115 for allowing the string 120 to pass therethrough.

  The configuration of the string 120 will be described. As shown in FIG. 5, the string 120 connects the first string 125 connected to the movable lever 110, the second string 126 connected to the operation lever 150 side, and the first string 125 and the second string 126. A connecting fitting 127.

  The first string 125 is a flexible linear member made of a fiber, and one end portion is connected to the movable lever 110 and the other end portion is connected to the connection fitting 127. . In the present embodiment, a plurality of balls (spherical members) 116 are fixed to the end of the first string 125 on the side connected to the movable lever 110. The plurality of balls 116 are arranged with a gap, and the movable lever 110 and the string 120 are connected by passing the portion of the string 120 between the balls 116 and the ball 116 through the slit 115. The ball 116 is housed inside the groove 113, and the movement of the ball 116 to be detached from the movable lever 110 is restricted by the movable lever engaging portion 112.

  As shown in FIG. 6, a part of the first string 125 is located inside the cleaning water tank 4. In this embodiment, when the float valve 450 is in the closed state, the tip of the movable lever 110 is directed downward, and a part of the first string 125 is immersed in the cleaning water stored in the cleaning water tank 4. It has become. In addition, when the float valve 450 is in the open state, the movable lever 110 faces in the horizontal direction. In this state, since the 1st string 125 is not pulled out outside, it will be located above the surface of the water. As described above, in this embodiment, a part of the first string 125 that moves as the movable lever 110 moves is immersed in the cleaning water in a part of the movable range of the movable lever 110.

The first string 125 is routed to the lower operation lever 150 side in contact with the upper edge 132 of the cleaning water tank 4 through the lower side of the protruding piece 131. In this embodiment, the round part 130 is formed in the part through which the 1st string 125 passes in the upper edge part 132. FIG. The round portion 130 has a curved surface that matches the direction in which the string 120 to be routed is bent, and is not slid and worn while the string 120 is in contact with the cleaning water tank 4.

  The sliding portion 128 that is a portion in contact with the cleaning water tank 4 in the first string 125 is a range determined by the movable range of the movable lever 110, the shape of the cleaning water tank 4, etc. (for example, the range shown in FIG. 6). . It can also be said that the sliding portion 128 of the first string 125 of the present embodiment is set closer to the movable lever 110 than the portion connected to the connecting bracket 127. Note that the range of the sliding portion 128 is appropriately changed depending on the shape of the apparatus and the like, and is not limited to the illustrated range.

  The connection fitting 127 is a connection part that connects the end of the first string 125 and the end of the second string 126 by caulking. As shown in FIG. 6, when the float valve 450 is in the closed state and the movable lever 110 is facing downward, the coupling fitting 127 has the float valve 450 in the closed state, and its lower end is lower than the predetermined water level WL. It is set to be positioned above. As a result, the lower end of the second string 126 (the end on the side of the connection fitting 127) is held at a position higher than the predetermined water level WL. The predetermined water level WL is a water level determined in advance by the amount of water normally stored in the cleaning water tank 4.

  The connecting fitting 127 connects the portion closer to the operation lever 150 than the sliding portion 128 of the first string 125 and connects the upper end of the second string 126. In this embodiment, the 1st string 125 and the 2nd string 126 are connected so that it may not contact inside the connection metal fitting 127. FIG.

  The second string 126 is a flexible linear member made of fiber, and one end of the second string 126 is connected to the connection fitting 127 and the other end is connected to the operation lever 150. . The second string 126 passes around the base plate 3 and is routed to the operation lever 150 side.

  In the present embodiment, a plurality of balls 121 are also fixed to the end of the second string 126 connected to the operation lever 150 side, and the operation lever 150 is engaged with the plurality of balls 121. An engaging portion 160 is provided (see FIG. 3). By engaging a plurality of balls of the second string 126 with the operation lever engaging portion 160, the operation lever 150 and the second string 126 are connected. As a result, the operation lever 150 is connected to the movable lever 110 via the first string 125, the connecting bracket 127, and the second string 126.

  A method of using the operation lever 150 will be described. First, the user pulls the operation lever 150 downward from the fitting hole 180 (see FIGS. 2 and 3). By pulling the operation lever 150 downward with the operation lever 150 removed from the base plate 3, the movable lever 110 rotates to one side, and the output shaft 552 rotates in a direction to open the float valve 450, thereby cleaning water. The water stored in the tank 4 is sent to the toilet body 2a.

  When the operation lever 150 is not used, the operation lever 150 is fitted in the fitting hole 180 (see FIG. 2). As described above, when the float valve 450 is closed, a part of the first string 125 is immersed in the cleaning water of the cleaning water tank 4. Since the first string 125 and the second string 126 are connected to each other on the outer side of the cleaning water tank 4 in a state of being isolated by the connection fitting 127, the first lever 125 made of fibers is connected to the operation lever 150 side by capillary action. Even if water tries to permeate, the connection fitting 127 prevents water from penetrating into the second string 126 on the operation lever 150 side, so that the above-described manual operation using the operation lever 150 can be reliably performed. .

According to the toilet bowl cleaning device 1 of the present embodiment described above, the following effects can be obtained.
The toilet bowl cleaning device 1 of this embodiment is disposed inside the toilet bowl body 2a, the washing water tank 4 for storing the washing water to be sent to the toilet bowl body 2a, and the inside of the washing water tank 4, and supplies the washing water to the toilet bowl body 2a. Alternatively, the float valve 450 that switches the stop, the first string 125 that is directly or indirectly connected to the float valve 450 inside the washing water tank 4, and the operation lever 150 that opens and closes the float valve 450 are connected. The 2nd string 126 and the connection metal fitting 127 which connects the 1st string 125 and the 2nd string 126 at intervals on the outer side of the washing water tank 4 are provided.

  As a result, even when water soaks into the first string 125, the penetration of water into the second string 126 can be reliably prevented by the connection fitting 127. Further, since the connection fitting 127 is located outside the washing water tank 4, it is possible to realize a structure capable of cutting off the penetration of water even when there is no extra space inside the washing water tank 4.

  The end of the first string 125 of the present embodiment on the side of the connection fitting 127 is positioned at a height equal to or higher than a predetermined water level WL set in the cleaning water tank 4 at least when the float valve 450 is closed.

  As a result, the position of the end of the first string 125 on the side of the connection fitting 127 is held at a height equal to or higher than the predetermined water level WL, so that even if water penetrates the first string 125, the water is lowered by the siphon effect. The situation which tries to move to the 2nd string 126 side of the side can be prevented effectively.

  The first string 125 of the present embodiment is arranged so as to be pulled out while sliding on the upper edge 132 of the cleaning water tank 4 when the operation lever 150 is pulled. The operation lever 150 is disposed closer to the cleaning water tank 4 than the range (sliding portion 128).

  Accordingly, it is possible to avoid a situation in which the connection fitting 127 interferes with the washing water tank 4 when the operation lever 150 is pulled, so that manual operation by the operation lever 150 can be performed smoothly, and the connection fitting 127 can be used for the washing water tank 4. It is also possible to prevent a situation where the first string 125 and the second string 126 are disconnected due to contact with each other.

  The 1st string 125 and the 2nd string 126 of this embodiment are connected by being crimped and fixed to the connection metal fitting 127. Thereby, since the 1st string 125 and the 2nd string 126 are connected on the outer side of the washing water tank 4, the metal material can be used without worrying about rust and the like. The operation of connecting the two strings 126 can be facilitated.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to the above-described embodiment, and can be modified as appropriate.

  In the above-described embodiment, the example in which the first string 125 and the second string 126 are coupled by caulking using the coupling bracket 127 made of metal as the coupling member has been described, but the material and shape of the coupling member depend on the circumstances. Can be changed as appropriate. For example, it is possible to use a structure in which a material of the connecting member is made of resin, and a structure in which the connecting member is integrally formed with the string or a fitting type structure in which the string and the string are fitted is formed of the resin material.

  In the said embodiment, although the movable lever and the operation lever were both demonstrated as an example the structure connected to the string 120 using a some ball, it is not limited to this structure. The configuration for connecting the string 120 can be changed as appropriate according to circumstances.

  In the above embodiment, an example in which the first string 125 is immersed in water inside the cleaning water tank 4 has been described, but the present invention is also applied to the case where the first string is not immersed in water inside the cleaning water tank. Can be applied. For example, even if the first string has a structure that is always positioned above a predetermined water level (water surface) of the washing water tank, the steam is filled inside the washing water tank 4 and water penetrates into the first string. There is. Even in such a case, as in the above-described embodiment, the first string 125 and the second string 126 are connected to each other by the connecting fitting 127 outside the cleaning water tank 4, so that water can be reliably penetrated to the operation lever side. Can be prevented.

  In the above embodiment, the first string 125 is configured to be indirectly connected to the float valve 450 as the on-off valve via the movable lever 110 as the interlocking member, but the first string 125 is directly connected to the on-off valve. It can also be set as the structure connected.

  In the above-described embodiment, the operation lever 150 is connected to the second string 126 as an operation member, but the configuration of the operation lever 150 can be appropriately changed according to circumstances. For example, the portion of the string that is continuous with the end of the second string can be used as the operating member, and the opening / closing valve can be opened and closed by pulling the string directly.
