Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a sanitary cleaning device having a built-in nozzle device for spouting hot water for cleaning and disposed in a toilet bowl body.

[Conventional technology]

Conventionally, sanitary cleaning devices fixed to the toilet bowl body for private cleaning have a hot water tank that heats and stores cleaning water in a casing, a nozzle device that spouts heated cleaning water, and a valve unit that supplies and adjusts the flow rate of cleaning water. The structure is equipped with a hot air fan for drying after cleaning.

Each of these devices is fixed to a mounting board, covered by a casing integrated with the mounting board, and housed in a state insulated from the outside.

There are various types of casing depending on the configuration of the sanitary cleaning device, but there is an upper casing located above the mounting board, a side casing located on one side that houses a hot water tank, etc., and a casing located above the side casing. Usually, it is divided into an operating part casing and an operating part casing on which various switches for operation are arranged on the surface.

[Problem that the invention attempts to solve]

Since each of these casings is made of synthetic resin in order to reduce weight and facilitate manufacturing, the edges tend to deform, and this is prevented by using screws or uneven fitting.

However, connecting the casings with screws is difficult in terms of productivity because it takes time to assemble.
Further, there is also a problem that the joining force is insufficient due to the uneven fitting, resulting in deformation of the edge of the casing.

An object of the present invention is to enable connection of a sanitary cleaning device in which a plurality of casings are integrated to house internal equipment without deforming the edges of the casings.

[Means and actions for solving problems]

The present invention is a sanitary cleaning system in which an upper casing that covers the equipment from above and an operation part casing in which switches, etc. are located are fixed to the top surface of the mounting board on which the cleaning equipment is placed, and the boundary between the two casings is butted and connected. In the device, a reinforcing rib with a notch formed at the lower end is provided on the inner side wall of the upper casing, and an engaging piece is provided in the operating part casing that extends in the direction of the upper casing and fits into the notch, The engagement between the engagement piece and the reinforcing rib prevents the upper casing side wall from deforming.

〔Example〕

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

Figure 1 is a perspective view of a flush toilet equipped with a sanitary cleaning device A according to the present invention, where B is the toilet body, C is a flush water tank for cleaning the toilet, D and E are the toilet seat and toilet lid, and F is a sanitary toilet. This is a cleaning nozzle main body extending from a nozzle device built into cleaning device A.

Fig. 2 is an exploded perspective view showing each casing of the sanitary cleaning device A, in which 1 is a mounting board for fixing each device, 2 is an upper casing, 3 is a side casing, and 4 is an operating part casing. be.

The mounting board 1 is connected to the toilet bowl main body B, and communicates with a hot water tank for heating and storing the washing water, a valve unit for supplying the washing water, and the hot water tank, and drives the washing nozzle main body F forward and backward to eject the washing water. Equipment such as a nozzle device (none of which is shown) is fixed.

Both the upper and side casings 2 and 3 are screwed with screws 5.
is connected and fixed at a predetermined position on the mounting board 1,
The operating part casing 4 is also fixed to the left part of the mounting board 1 with screws 6.

The front left part of the upper casing 2 and the back part of the operating part casing 4 fit together and become integrated.
As shown in FIG. 3, a convex portion 7 and a concave portion 8 for fitting are formed on the inner and outer surfaces of both casings 2 and 4, respectively.

Reference numeral 10 denotes a reinforcing rib provided inside the side wall 11 of the upper casing 2. A notch 12 for engagement is formed at the lower end between the side wall 11 and the inner edge 17 of the notch 12, as shown in FIG. As shown, a slope 18 is provided so that the cutout section at the lower end becomes larger.

Further, a flange 15 through which the screw 6 is inserted is provided on the lower surface of the back of the operating portion casing 4, and an engaging piece 16 that fits into the notch 12 of the reinforcing rib 10 from below is integrally formed.

Lower left end of upper casing 2 and side casing 3
As shown in FIG.
The projections 20 and the holes 21 fit together to integrate the casings 2 and 3.

This operating part casing 4 and side casing 3
The connection between the upper casing 2 and the upper casing 2 is carried out by fitting the protrusion 7 of the upper casing 2 into the recess 8 of the operating section casing 4 from above.

At this time, the engaging piece 16 enters into the notch 12 of the reinforcing rib 10 of the upper casing 2 as shown in FIG. receive. This acting force is caused by the relative positions of the notch 12 and the engaging piece 16, so that the engaging piece 16 applies an elastic reaction force to the inner edge 17 of the notch 12, and the lower edge of the side wall 11 is directed outward. Deformation such as opening is restrained. In addition, reinforcing rib 1
By providing the inclined portion 18 at the lower end of the inner edge 17 of 0, the engagement piece 16 can enter into the notch 12 smoothly.

At the same time as this engaging piece 16 is fitted into the notch 12, the protrusion 20 of the upper casing 2 engages with the hole 21 of the protruding piece 22 of the side casing 3, restraining upward movement and integrally connecting. .

Further, the upper casing 2 is removed by pushing the vicinity of the protrusion 22 of the side casing 3 from the outside. In this case, when the projection 20 and the hole 21 are disengaged, a frictional force acts between the projection 20 and the hole 21, and the side wall 11 of the upper casing 2 also tends to deform inward together with the side casing 3. However, this deformation is restrained by the reinforcing ribs 10 and does not deform. If the protrusion 22 portion of the side casing 3 is pushed, only this portion deforms inward, and the engagement between the protrusion 20 and the hole 21 is disengaged. The upper casing 2 can be removed.

As described above, the engagement piece 16 and the reinforcing rib 10 having the notch 12 allow the side wall 11 portion of the upper casing 2 to be connected without fixing with screws. Deformation can also be prevented.

[Effect of idea]

This invention uses the engagement force between the casings to connect them without the need for screws, so assembly is easy and there is no need to process screws or screw holes.
This has the effect of reducing production costs.
