<Configuration of cleaning operation device>
Next, a specific configuration of the cleaning operation device 6 according to the embodiment will be described with reference to FIGS. 3 to 5. FIG. 3 is a schematic cross-sectional view showing the cleaning operation device 6 according to the embodiment. Note that FIG. 3 shows an enlarged cross section of part A in FIG. FIG. 4 is an explanatory view of a mounting state in the case of the screw type operation rod 63. FIG. 5 is an explanatory view of a mounting state in the case of a press-fit type operating rod 63.

It should be noted that FIGS. 3 to 5 show only one of the above-mentioned sets for the large cleaning mode and the small cleaning mode in the cleaning operation device 6 (in the illustrated example, only the set for the small cleaning mode). There is.

As shown in FIG. 3 and as described above, the cleaning operation device 6 includes an operation button 61, a mounting member 62, and an operation rod 63. The operation button 61 is provided on the washing water tank device 3 (see FIG. 3). The operation button 61 is arranged substantially in the center of the upper surface of the lid portion 32 (see FIG. 3) and is exposed to the outside.

The operation button 61 is configured to be pressable by the user. When the operation button 61 receives an operation force (pressing force by the user) from the outside, the operation button 61 moves downward over a predetermined stroke. On the lower surface of the operation button 61, one engaging portion 611 for engaging with the mounting member 62 described later is formed.

The mounting member 62 is arranged on the lower surface of the operation button 61. The mounting member 62 is formed, for example, in a cylindrical shape. At one end (upper end) of the mounting member 62, the other engaging portion 621 for engaging with one engaging portion 611 of the operation button 61 is formed. The mounting member 62 extends downward from the lower surface of the operation button 61 in a state of being attached to the operation button 61.

In the present embodiment, the mounting member 62 is provided separately (as a separate member) from the operation button 61, but is provided integrally with the operation button 61 (as the same member), for example. May be good.

The mounting member 62 is formed with a hole (hereinafter, referred to as a through hole) 622 that penetrates the mounting member 62 from one end to the other. The through hole 622 extends in the vertical direction below the operation button 61 in the mounted state of the mounting member 62. The through hole 622 is formed so as to be surrounded by the inner wall surface 623 of the mounting member 62.

The operation rod 63 is formed in a columnar shape. The operation rod 63 is attached to the attachment member 62 by inserting one end portion 631 into the through hole 622 of the attachment member 62. When attached to the attachment member 62, the operation rod 63 extends in the vertical direction below the operation button 61 and the attachment member 62.

Further, in the operation rod 63, the other end (tip portion) 632 is lowered as the operation button 61 is lowered to press the pressure receiving surface 541 (see FIG. 2) of the drain valve device 5, thereby causing the drain valve device 5 to be pressed. Raise the drain valve body 53 (see FIG. 2).

Here, the operation rod 63 has two types of mounting methods for the mounting member 62: a screw type and a press-fit type. In the screw type, a threaded portion is formed at least at one end portion 631 of the operation rod 63, and the one end portion 631 is screwed into the threaded hole to be attached. In the press-fitting type, one end 631 of the operation rod 63 is attached by press-fitting one end 631 into a hole that has been subjected to diameter reduction processing.

Further, the operating rod 63 needs to adjust the rod length in order to match the distance to the pressure receiving surface 541 of the drain valve device 5. In the screw type, the length of the operating rod 63 is adjusted by changing the screwing amount (the amount of entry into the hole) of the operating rod 63. In the press-fitting type, the length of the operating rod 63 is adjusted by cutting the other end 632 side of the operating rod 63.

However, when the mounting method is a screw type or a press-fit type, the parts (mounting members and operation buttons) are different, and the screw type requires a screw type part and the press-fit type requires a press-fit type part, which increases the cost. Therefore, in the present embodiment, parts common to both the screw type and the press-fit type can be used.

As shown in FIG. 3, the mounting member 62 includes a first mounting portion 624 and a second mounting portion 625. The first mounting portion 624 and the second mounting portion 625 are formed on the inner wall surface 623. Further, the first mounting portion 624 and the second mounting portion 625 are aligned coaxially in the through hole 622.

The first mounting portion 624 corresponds to the case where the operating rod 63 is a screw type. The first mounting portion 624 is formed on the inner wall surface 623, and is formed by screwing the screw portion formed on one end portion 631 of the screw type operation rod 63 so as to be screwable.

As shown in FIG. 4, when the operation rod 63 is a screw type, the operation rod 63 is attached to the attachment member 62 by screwing one end portion 631 of the operation rod 63 into the first attachment portion 624. In this case, the length of the operating rod 63 is adjusted by changing the screwing amount of the operating rod 63 with respect to the first mounting portion 624.

The second mounting portion 625 corresponds to the case where the operating rod 63 is a press-fit type. The press-fit type operation rod 63 is simply a columnar rod. The second mounting portion 625 is formed above the first mounting portion 624 on the inner wall surface 623, and is formed by subjecting one end portion 631 of the press-fit type operation rod 63 to a diameter reduction process that allows press-fitting.

Further, the second mounting portion 625 includes a ridge 625a. The ridge 625a extends along the axial direction of the through hole 622 on the inner wall surface 623 of the second mounting portion 625. A plurality of ridges 625a are provided around the axis of the through hole 622 at predetermined intervals.

As shown in FIG. 5, when the operation rod 63 is a press-fit type, the operation rod 63 is attached to the attachment member 62 by press-fitting one end portion 631 of the operation rod 63 into the second attachment portion 625. In this case, the length of the operating rod 63 is adjusted by cutting the other end 632 (see FIG. 2) side of the operating rod 63.

Further, the mounting member 62 further includes a diameter-expanded portion 626. The enlarged diameter portion 626 is formed above the second mounting portion 625 on the inner wall surface 623, and has a diameter larger than at least the second mounting portion 625. The first mounting portion 624, the second mounting portion 625, and the enlarged diameter portion 626 are aligned coaxially in the through hole 622.

As described above, according to the cleaning operation device 6 according to the embodiment, the operation rod 63 is attached to the first attachment portion 624 in the case of the screw type, and the operation rod 63 is attached to the second attachment in the case of the press-fit type. Since it is attached to the portion 625, it is possible to deal with two types of attachment methods with one common component. That is, according to the cleaning operation device 6 according to the embodiment, it can be used for different mounting methods. As a result, the cost can be reduced.

Further, since the enlarged diameter portion 626 is formed above the second mounting portion 625, even when a tensile force acts on the operating rod 63, the operating rod 63 has a margin for entering the enlarged diameter portion 626. Therefore, the operating rod 63 does not immediately come off from the second mounting portion 625. That is, it is possible to suppress the operation rod 63 from falling off while performing the diameter reduction processing on the narrow range of the inner wall surface 623.

Further, when the operation rod 63 is press-fitted into the second mounting portion 625, the ridge 625a facilitates press-fitting. Further, when the operation rod 63 is attached to the second attachment portion 625, the ridge 625a imparts a holding force. By providing the convex ridge 625a on the second mounting portion 625 in this way, the operation rod 63 can be easily mounted and hard to come off.

Further, by providing two sets of the operation button 61, the mounting member 62 and the operation rod 63, it can be applied to the drain valve device 5 having the large cleaning mode and the small cleaning mode.

Further, according to the washing water tank device 3 according to the embodiment, in the washing operation device 6, one component common to two types of mounting methods can be used, and the washing operation device 6 can be used for different mounting methods. It can also be used for both purposes, and cost reduction can be achieved.

Further effects and variations can be easily derived by those skilled in the art. For this reason, the broader aspects of the invention are not limited to the particular details and representative embodiments expressed and described above. Therefore, various modifications can be made without departing from the spirit or scope of the general concept of the invention as defined by the appended claims and their equivalents.
