Description

[Detailed description of the invention] [Technical field of the invention] This invention is a so-called heated toilet seat device that is equipped with a function of washing private parts with hot water, a function of drying with warm air, or a heated toilet seat, and controls the heated toilet seat. This invention relates to improvements in the mounting structure of switch mounting boards on which various switches are mounted.

[Prior art]

In general, a heated toilet seat device is a toilet seat equipped with a heating function and a storage box 1 that has a built-in function to wash the private parts with hot water after defecating and to dry the private parts with warm air, as shown in Fig. 1, for example. The storage box 1 is installed at the rear of the toilet bowl 3 with the base of the toilet seat 2 mounted on the toilet bowl 3 such that the base of the toilet seat 2 is slidable. 4, hot water is jetted out, and during drying, hot air is discharged from a hot air outlet (not shown) near the cleaning nozzle 4. On the side of the storage box 1, there are push buttons 5 for various switches that control the hot water toilet seat device A, such as a switch for operating the washing and drying functions or a stop switch for stopping them, and a switch for heating the toilet seat 2. placed on the surface,
An operation box 6 is integrally formed therein, and houses a hot water washing device, a hot air drying device (not shown) in the storage box 1, or a control device for controlling the temperature of the toilet seat 2. Various switches for controlling the warm water toilet seat device A are the sixth switch.
It is installed as shown in Fig. 7. That is, in the same figure, 7 is a printed circuit board on which various electronic components (not shown) constituting the control device are attached. Align and place on the bottom of case 8. 10 is a cover that covers the case 8, and inside this cover 10, a switch 11 for operating and stopping each function of the heated toilet seat device A and a light emitting diode 12 that serves as an indicator light are installed. A switch mounting board 13 is screwed to a boss 14 for fixing the mounting board that hangs down from the cover 10 by a certain length. A fitting hole portion 15 is bored in the
The push buttons 5 are fitted into the fitting holes 15, and the push shafts 5a formed integrally with the push buttons 5 are made to protrude into the cover 10 so that each switch 1
A thin sheet 16 made of polyurethane resin or the like is attached to the surface of the cover 10, and when the cover 10 constructed in this manner is placed over the case 8, the cover 10 is brought into contact with the switch mounting board 13. It is fixed to the case 8 by screwing the tightening screw 17 passed through the mounting boss 9 into the boss 18 of the cover 10 while the cover is loosely engaged with the mounting boss 9 and suspended inside the case 8. Ru. In the figure, 19 is a flat cable that connects the control device and the switch 11. Since the various switches 11 are mounted on the switch mounting board 13 fixed to the fixed boss 14 of the cover 10 as described above, the switch mounting structure has the following drawbacks.

(1) When inspecting the finished product after assembling the hot water toilet seat device, since the cover 10 is already fixed to the case 8, there is no problem when measuring the temperature and jet power of hot water and hot air by operating the switch 11. However, if there is a water leak inside the case 8 or a poor wiring connection occurs, it is necessary to remove the cover 10 from the case 8 and perform inspection and repair each time. Also,
When attaching or detaching the cover 10, since the switch mounting board 13 is fixed to the cover 10 side, the cover 10 cannot be attached or detached quickly during assembly unless a long flat cable is used.

(2) Before attaching the cover 10 to the case 8, check for water leaks and wiring.
Connect the flat cable 19 to a dummy switch operation panel (not shown) while leaving the inside exposed to the outside.
It is possible to perform the measurements described in (1) by connecting the
After attaching cover 10, switch 1 again.
Since it is necessary to perform the inspection in step 1, the final inspection is time-consuming.

To solve this problem, switch 11
By fixing the mounting board 13 to the case 8 side, a complete inspection can be easily performed before assembling the cover 10. However, in this case, if the joint between the case 8 and the cover 10 or the length of the other bosses 14 and 18, including the mounting boss 9, are not all molded according to the designed dimensions, when assembling the case 8 and the cover 10, for example, , the push button 5 is pushed up to the upper part of the cover 10 more than necessary, and as a result, the push button 5 is pressed by the elastic force of the thin sheet 16 and the switch 11 is kept on all the time, or vice versa. Since the lower part of the push shaft 5a is located at the bottom of the fitting hole 15, a gap is created between the tip of the push shaft 5a and the switch 11, resulting in the disadvantage that the switch 11 cannot be turned on after the cover 10 is assembled.

[Purpose of invention]

This idea eliminates the shortcomings of the previous model and places the switch mounting board inside the case without having to specifically fix it to the case or cover, allowing the switch to be directly exposed to the outside during product inspection. To provide a hot water toilet seat device which can be easily installed and which eliminates the trouble caused when a cover is attached to a case due to an error in molding dimensions by always keeping the distance between the cover and a switch mounting board constant. It's about doing.

[Summary of the idea]

This idea supports the switch mounting board on which various switches for controlling the various functions of the hot water bidet toilet seat, i.e., hot water, warm air, and toilet seat temperature are attached, to the case side of the hot water bidet toilet seat via a spring, and the switch mounting board is attached to the cover side. A stopper pin is installed to maintain a constant distance between the cover and the switch mounting board.During the final inspection, the switch is exposed to the outside without the cover attached.When the cover is attached after the inspection, the switch is attached using the stopper pin. The present invention is characterized in that the distance between the board and the cover is maintained constant, and the cover can be attached to ensure that the switch can be turned on.

[Example of idea]

Examples of this invention will be described below with reference to FIGS. 2 to 5. In addition, in FIGS. 2 to 5,
The same reference numerals as in FIG. 1, FIG. 6, and FIG. 7 indicate the same parts.

The difference between the switch mounting board mounting structure of this invention and the conventional one is that, as shown in FIG. 3, this invention supports the switch mounting board 13a within the case 8 using a compression spring 20. A stopper pin 21 is provided on the back surface of the cover 10a to maintain constant dimensions between the cover 10a and the mounting board 13a.

Initially, the compression spring 20, as shown in FIG.
A stepped portion 9a located approximately in the center of a mounting boss 9 provided on the case 8, and a retaining ring 2 that is attached to the upper end of the mounting boss 9.
It is inserted between 2. When installing the switch mounting board 13a, first, one end of the printed circuit board 7 on which the electronic component 7a constituting the control device of the heated toilet seat device A is attached is fitted into one of the mounting bosses 9, and the other end is inserted into the other end. The switch mounting board 13a is fixed between the locking pieces 9a and 9b provided on the mounting boss 9 and placed on the bottom surface of the case 8, and then the various switches 11 and light emitting diodes 12 are attached.
is inserted into the upper part of the mounting boss 9 via the compression spring 20, and then the retaining ring 2 is attached to the upper end of the mounting boss 9.
By fixing 2, the switch mounting board 13
As shown in FIG. 4, a is supported by the mounting boss 9 while being pressed upward by the biasing force of the compression spring 20 and received by the retaining ring 22. After the switch mounting board 13a is supported on the mounting boss 9 as described above, the switch mounting board 13a and the printed circuit board 7 are connected with the flat cable 19, and the finished product is inspected in this state. That is, as shown in FIGS. 4 and 5, since the switch mounting board 13a is exposed to the outside, the completion test was conducted by controlling the temperature of the hot water and hot air attached to the switch mounting board 13a within a predetermined range. The function of the hot water toilet seat device A is directly checked by the inspector directly operating the switch 11a that can be raised or lowered within the toilet seat, and the switches 11 for "cleaning", "drying", "toilet seat", and "stop". be able to. At this time, since the cover 10a is not attached to the case 8, the inspector can
1 and 11a, the interior of the hot water toilet seat device A can be inspected, and if any defective parts are found, repairs or replacement of parts can be easily carried out.

After the completion inspection of the product is completed, the case 8 is covered with the cover 10a. In this case, on the back side of the cover 10a, the
As shown in the figure, the stopper pin 21 is formed to protrude downward with a length that allows the push shaft 5a of the push button 5 to come into contact with the head of the switch 11.
When the cover 10a is placed on the case 8, the stopper pin 21 collides with the upper surface of the switch mounting board 13a, pushes it down a little against the force of the compression spring 20, and in this state penetrates the inside of the mounting boss 9. Tightening screw 17 that screws into the boss 18 for fixing the cover

When cover 10a is fixed to case 8, cover 1
Since the distance between 0a and the switch mounting board 13a is maintained at a constant length by the stopper pin 21, the distance between the case 8 and the cover 10a, or the mounting boss 9 and the cover 10a fixing boss 1
Even if the length of 8 is slightly increased or decreased from the design dimension during molding, the switch mounting board 13a can be moved up and down along the mounting boss 9 while maintaining a constant distance from the cover 10a. Therefore, there is no problem with the closing operation of the various switches 11 using the push button 5, and the switch operation can always be carried out smoothly.

[Effect of idea]

This idea is structured as above, so
It has the following effects.

(1) The heated toilet seat device can be inspected after completion before putting the cover on the case.
This has the advantage that the inspection work can be carried out without using a special switch operation panel or making the flat cable longer than necessary, and that the interior of the heated toilet seat device can be checked reliably.

(2) The switch mounting board, on which various switches for controlling hot water, hot air, etc. of the hot water toilet seat device are attached, is supported in the case so that it can move up and down via a compression spring, and the cover and switches are attached to the case. A stopper pin is provided to maintain a constant distance from the mounting board, so even if dimensional errors occur during molding of the case or cover,
This dimensional error is absorbed by a compression spring, and
Since the cover can be attached to the case while always maintaining a constant distance between the cover and the switch mounting board, there is also the advantage that the switch operations can be performed reliably without hindrance to the closing operations of various switches.

(3) Also, since the switch mounting board is supported by a compression spring, when the switch is turned on, the cover can be attached to the case while maintaining a constant distance between it and the switch mounting board.
Another advantage is that the switches can be operated reliably without hindrance to the closing operations of various switches.

(4) In addition, since the switch mounting board is supported by a compression spring, even if an excessive load is applied to the switch when the switch is turned on, the load is absorbed by the compression spring and the switch mounting board It is also possible to prevent the switch from being damaged.
