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 this side casing. Usually, it is divided into an operating part casing located above the main body and having various operating switches arranged on its surface.

In this way, a plurality of casings are mounted and integrated into a board, and the casings are connected by screws or stepped portions 52 and 53 that engage with each other at the edges of the casings 50 and 51 as shown in FIG. The step portions 52 and 53 are connected by butting each other.

[Problem that the invention attempts to solve]

Here, the sanitary cleaning device itself is a water-related equipment, and it is essential to keep it sanitary at all times, so even if the casing 50 and 51 surfaces get wet with cleaning water, or when cleaning, etc., wipe the surface with a wet rag. There are many things.

However, if the stepped portions 52 and 53 are simply butt-connected, the joint surface between the stepped portions 52 and 53 cannot be sealed unless a gasket is attached or caulking is applied, and water cannot be prevented from entering.

In addition, since the joining surfaces are continuous on both the front and back surfaces of the casings 50, 51, if the machining accuracy is insufficient or the mutual joining force loosens after assembly, the stepped portions 52, 51
There will be a gap between the three.

Therefore, if there is a gap or the like in the joint, there is a problem in that water can penetrate inside and damage the electrical equipment.

The purpose of the present invention is to connect and seal the joints between the casings with a simple structure in a sanitary cleaning device that integrates multiple casings and stores equipment therein, thereby simplifying the assembly and protecting the internal equipment. The purpose is to ensure protection.

[Means and actions for solving problems]

The present invention is a sanitary cleaning device in which at least two or more casings are integrated into a mounting board on which various devices for cleaning functions are arranged and fixed to the toilet bowl body. A concave groove and a convex part that fits into the concave groove are formed around the entire circumference of the back side edge of the other casing, and both casings are connected by fitting the concave groove and the convex part, and both casings are connected at the joint part. This allows the water that enters the tank to be discharged along the groove.

〔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 a partially cutaway plan view of the sanitary cleaning device A, and Fig. 3 is a partially cutaway side view according to the - line position in Fig. 2, where 1 is a mounting board for fixing each device, and 2 is an upper part. The casing, 3 is a side casing, and 4 is an operating part casing.

A hot water storage tank 20 for heating and storing cleaning water is housed in the side casing 3, and a valve unit 21 and a hot water storage tank 20 for supplying cleaning water are housed in the mounting board 1.
Equipment such as a nozzle device 22 that spouts out cleaning water supplied from the nozzle device 22 is fixed.

This side casing 3 is integrally connected to the lower surface of the mounting board 1 by screws or the like. Further, a control section 25 is fixed to the operation section casing 4, and the control section 25 is fixed to the operation section casing 4.
The screw 2 is inserted into the side casing 3 and passes through the flange 26 provided on the back as shown in FIG.
7 to the mounting board 1, and then the upper casing 2 is fixed to the mounting board 1 and assembled.

FIG. 4 is a perspective view showing the main parts of the upper part and the operating part casings 2 and 4, in which a groove 5 is formed around the entire circumference on the rear end surface of the operating part casing 4, and the outer shape of the edge is the same as that of the casing surface. A smaller engagement step 6 is provided.

At the part where the upper casing 2 joins the operating part casing 4, a convex part 7 that fits into the groove 5 of the operating part casing 4 is formed around the entire edge, and a recessed part 8 that engages with the engagement step part 6 is formed. It is set up.

In the above casing structure, the upper and operating section casings 2 and 4 are connected by fixing the operating section casing 4 to the mounting board 1 with the screws 27 as described above, and connecting the tip side of the upper casing 2 to the edge of the operating section casing 4. Cover it from above.

By this connection, as shown in FIG. 5, the convex part 7 and the concave part 8 of the upper casing 2 are fitted with the engaging stepped part 6 of the operating part casing 4 in between, and are integrated. In addition, in this fitting, the concave groove 5 and the convex part 7
The height of the engagement step 6 and the depth of the recess 8 are formed such that a gap 9 for water discharge exists between the two over the entire circumference.

The fitting of the concave groove 5 and the convex part 7 is done because the joint surfaces of the upper part and the operation part casings 2, 4 are not in a straight line, but are discontinuous on both the front and back sides of both the casings 2, 4 over the entire circumference. Even if water intrudes into the joint portion, this intruding water does not directly infiltrate the back surfaces of both casings 2 and 4, but can be discharged downward along the bottom surface of the groove 5 of the gap 9.

Therefore, even without performing any sealing treatment, it is possible to prevent water, dust, etc. from entering the casing, and the internal equipment can operate normally without being damaged, thereby improving durability.

In this embodiment, the connection between the upper casing 2 and the operating part casing 4 has been described, but other casings can be connected in the same way.

[Effect of idea]

This invention has a simple structure that does not require sealing, etc., and can protect internal equipment by preventing water from entering from the outside, resulting in reliable equipment operation and improved durability. be effective.
