Polymerization and fixing can be performed as in the case of using the external tightening member.

When the sanitary washing device X is repaired, the upper casing 1
When opening 1a, the screw 7a on the rear wall side is removed, and then the tip of a flat-blade screwdriver is inserted into the recess 23 on the lower side of the front wall 20b of the lower casing 11b, and the front wall 20a of the upper casing 11a corresponding to the recess 23 is opened. When the hook is bent to the front side, as shown in FIG. 8, the hooking frame 25 hooked in the recess 23 can be easily removed and the upper casing 11a.
Can be covered. Further, after the repair, as described above, by placing the upper casing 11a on the lower casing 11b and lightly pressing it, the first and second hook portions 21 and 22 can be easily hooked and engaged. In this state, the rear wall overlapping portion 6a of the casing 11 may be fastened with the screw 7a. Although the present invention has been described with reference to the embodiment in which the second hook portion 22 is engaged in an inclined state, the present invention is not limited to this, and the front wall 20a of the upper casing 11a may be moved by the force generated when the toilet seat 14 or the like stands up. In order to prevent the spring from jumping up in the clockwise direction, for example, the present invention can be realized even if the engagement protrusion and the engagement receiver are vertically engaged.

[Effect of device]

Since the present invention is configured as described above, it has the following effects.

According to the present invention, in a casing of a sanitary washing device configured by superimposing and fixing an upper casing and a lower casing, a superposing portion on a front wall side of the casing is separated into the upper and lower casings, respectively, and A first hook portion including an engagement frame and an engagement step portion that are formed to be engageable with each other, and a second hook portion including an engagement protrusion and an engagement receiver so as to engage and disengage freely. Since it is configured to be combined and fixed, the conventional sanitary washing device is constructed by completely eliminating the adverse effects such as rust caused when fixing with screws, and polymerizing the upper and lower casings. The casing can be kept hygienic and beautiful for a long period of time.

Further, a first hook portion composed of a latching frame of the upper casing and a latching step portion of the lower casing hooks the latching frame and the latching step portion, and thereby the upper and lower casings. Since the overlapping portion on the front wall side can be hooked and held in one operation, the upward movement of the upper casing in the overlapping portion can be reliably prevented. Further, the second hook portion composed of the engagement protrusion of the upper casing and the engagement receiver of the lower casing engages and holds the engagement protrusion and the engagement receiver, thereby superimposing the upper casing on the lower casing. In such a case, it is possible to satisfactorily receive the jumping force that acts on the upper casing when standing up such as a toilet seat, so that the overlapping portion is fixed on the front wall side of the casing formed by overlapping the upper casing and the lower casing. Can be performed quickly, reliably, and smoothly without resorting to fixing means using screws.

According to the present invention, when assembling the casing of the sanitary washing device including the upper and lower casings, the upper and lower casings include a hooking frame and a hooking step which form a first hook, and a second hook. Engaging projections and engaging receivers that form the hooks of the above are respectively formed, and when the upper casing is covered with the lower casing and lightly pressed from above, the upper casing of the upper casing has the second hook portion of the guide. Since the first hook portion, which plays a role and includes the hook frame and the hook step portion, can be easily hooked and fixed in one operation, the casing assembling work in the sanitary washing device can be performed quickly and easily. it can. Moreover, when the upper and lower casings are molded by resin, the first and second hook portions can be integrally formed with the upper and lower casings, and the forming place is also narrow in the casing. Since the space can be effectively utilized, the casing for housing the washing water heating device and the nozzle device, which form the main part of the sanitary washing device, is not particularly enlarged, In addition, since it is possible to reduce the use of fixing means such as screws and simplify the assembling work, there is an advantage that this kind of casing can be economically manufactured.
