Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathroom operating device attached to a flange of a bathtub and operated by a person.

[0002]

2. Description of the Related Art For example, a drainage plug device as disclosed in Japanese Patent Application Laid-Open No. H10-212747 and Japanese Patent Application Laid-Open No. H1-124186.
An operation device for operating them is provided in a jet bath device or the like as disclosed in Japanese Patent Application Laid-Open Publication No. H11-163873.

[0003] The operating device is installed in such a manner that it is hung below the bathtub flange, and specifically, it is installed in the following manner.

First, the case of the operating device is fitted into the through hole of the bathtub flange from above the bathtub flange,
The upper surface of the case is made substantially flush with the upper surface of the bathtub flange by hooking a radially outward flange provided at the upper end of the case on the bathtub flange.

Next, a nut is screwed from the lower surface of the bathtub flange to the outer peripheral surface of the case, and the nut is brought into contact with the lower surface of the bathtub flange. It is designed to be fixed in a sandwiched form.

[0006]

The following problems are pointed out in the bathroom operating device described above.

In general, the lower space of the bathtub flange is hidden by a bathtub apron. Therefore, when attaching or detaching the operation device, the bathtub apron must be removed or the makeup of an inspection window provided in the bathtub apron. With the lid removed, it is necessary for the worker to insert his hand into the space below the bathtub flange and tighten or loosen the nut, and the worker must bend down and work in an unnatural posture. Therefore, it can be said that the workability is poor.

On the upper surface of the case, characters indicating opening / closing of a drain plug and characters indicating ON / OFF of a whirlpool are described. These characters are oriented in a predetermined direction of a bathtub flange. Need to be placed.

However, if the worker is in the above-described working posture, the worker cannot see the case from above the bathtub flange. Therefore, the characters on the case indicate the orientation of the bathtub flange by tightening the nut. Can only be confirmed after In this case, it is necessary to repeat the tightening work of the nut many times, so usually, first, with the nut temporarily tightened, set the above character so that it faces the appropriate direction, then tighten the nut tightly It is quite troublesome work, for example, the work cannot be performed simply continuously.

In view of such circumstances, an object of the present invention is to simplify the operation of attaching and detaching a bathroom operating device.

Next, the structure and installation form of the operating device 5 in the drain plug unit 3 will be described in detail.

An operation button 9 which is pressed by a human being is embedded in the operating device 5, and a through hole 10 for emitting upwardly the light of an LED 17 indicating the state of the drain plug 4 described below is provided. Is provided. The above-described through-hole 10 may be filled with a transparent resin material or the like. Further, inside the operation device 5, a driving means (omitted by reference numerals) for pushing and pulling the wire 6 in response to the pressing operation of the operation button 9 is incorporated.

The driving means includes a stepping motor 11
And a control circuit board 12.

The stepping motor 11 has a generally well-known structure, but has a rotor 11a rotatably supported so as not to be displaceable in the axial direction. This rotor 11a
A slide shaft 13 provided with a male screw in a required area on the outer peripheral surface is screwed into the screw hole at the center. A wire 6 is connected to the lower end of the slide shaft 13 via a coupling 14.
Are connected at one end. The slide shaft 13 cannot be rotated by the guide bar 15 and can be displaced only in the axial direction. When the rotor 11a rotates, the slide shaft 13 moves linearly in the vertical direction. In other words, the slide shaft 1 is driven by the feed action of the screw connection between the rotor 11a and the slide shaft 13.
3 is moved linearly in the vertical direction.

The control circuit board 12 controls the operation of the stepping motor 11 in accordance with the pressing operation of the operation button 9 by a person. The switch is turned on / off in conjunction with the pressing operation of the operation button 9 by a person. An LED 17 is provided at the lower end of the through hole 10 and is turned on and off according to the open / close state of the drain plug 4. Further, the control circuit board 12 receives a signal line 18 of the stepping motor 11 and a power supply from a water heater main body (not shown) and receives a control signal from the water heater main body while transmitting a status signal to the water heater main body. Signal line 19 to be transmitted
Are detachably connected by a connector.

Next, the housing structure of the operating device 5 will be described. As a housing of the operation device 5, an upper case 21, a lower case 22, and a frame 23 are used.

First, the upper and lower cases 21 and 22 are formed in a cylindrical shape, and are flanged to each other by bolts. The upper case 21 has its upper end closed and its lower end opened. The lower case 22 has its upper and lower ends opened. The upper half of the upper case 21 has a small diameter, and the lower half has a large diameter.
An external thread is formed on the outer peripheral surface of 1a. A bottomed cylindrical cup 24 is attached to the lower end opening of the lower case 22. At the center of the lower end of the cup 24, a through hole 24a through which the slide shaft 13 of the driving means is inserted is provided.

The frame 23 has a shape in which an inward flange 23b projecting inward in the radial direction and an outward flange 23c projecting outward in the radial direction are provided at the upper end of the cylindrical portion 23a. A female screw is formed on the inner peripheral surface of the cylindrical portion 23 a of the frame 23, and the frame 23 is screwed to the outer periphery of the upper case 21. Thus, the frame 23 is
1, the lower end of the frame 23 is received by the end surface 21e of the small diameter portion 21a of the upper case 21 and the outer peripheral surface of the cylindrical portion 23a of the upper case 21 is fixed to the outer periphery of the small diameter portion 21a of the upper case 21. Be flush with the plane.

The above-mentioned operation button 9 and LED 17 are embedded and installed in the upper case 21, and the respective elements constituting the above-mentioned driving means (reference numerals are omitted) in the upper and lower cases 21 and 22 are watertight. It is stored in a state.

The upper and lower ends of the operation button 9 and the through hole 10 are exposed at the upper and lower ends of the upper case 21.

In order to make the operation device 5 watertight, an O-ring 3 is provided at a flange connecting portion between the upper case 21 and the lower case 22 and a connecting portion between the lower case 22 and the cup 24.
1 and 32, and the through hole 24 of the cup 24
a and two O-rings 33 and 34
Further, a circular thin plate 35 that covers the operation buttons 9 and the through holes 10 is adhered to the upper end surface of the upper case 21 to make the exposed portion of the upper end surface of the upper case 21 airtight. On the circular thin plate 35, a mark indicating the position of the operation button 9, a character indicating the function of the operation button 9, and a mark indicating the position of the LED 17 which blinks and lights when the drain plug 4 is opened and closed are described. In order to expose the marks and characters on the circular thin plate 35 to the outside, the upper end opening window of the frame 23 is formed as shown in FIGS.
As shown in the figure, the shape is like a butterfly spreading its wings.

At the lower end of the lower case 22, a cylindrical bulging portion 22a is provided.
a, a through hole 22 for inserting the signal line 19 described above.
b is provided. Since a slight gap is formed between the through hole 22b and the signal line 19, the gap is sealed using an elastic ring 25. More specifically, the elastic ring 25 is fitted to the signal line 19 protruding outside from the bulging portion 22a of the lower case 22, and the cap nut 26 is fitted over the elastic ring 25 to expand the cap nut 26. It is screwed to the projection 22a. By doing so, the cap nut 26 is tightened,
The elastic ring 25 is elastically compressed in the direction of its central axis, whereby the elastic ring 25 fitted on the inner periphery of the cap nut 26 expands radially inward, thereby causing the signal line 19 to expand. As a result, the gap between the signal line 19 and the through hole 22b is closed.

Further, an airtightness test nozzle 27 for performing an airtightness test of the internal space of the upper and lower cases 21 and 22 is provided at a predetermined position on the outer peripheral surface of the lower case 22. In this airtight test, a predetermined air pressure is applied to the internal space in a state where the internal spaces of the upper and lower cases 21 and 22 and the airtight tester (not shown) are connected and connected through the airtight test nozzle 27, and the pressure decreases. This is to check whether or not to do so. When this airtight test is completed, the airtight test nozzle 2
7 is closed by a screw 28 or the like.

Also, at two positions on the outer periphery of the upper end opening window of the frame 23, an angle range of approximately 120 degrees is provided with ridges 23d, 23d that bulge in a mountain shape. The raised portion 23d is for preventing a bather or the like from touching the operation button 9 by mistake. Here, if the raised portion 23d is formed in a ring shape continuous in the circumferential direction, it is advantageous in preventing erroneous operation. However, in the case where the raised portion 23d is formed in a ring shape, hot water remains in the inner peripheral portion thereof. However, as described above, if two ridges 23d are provided discontinuously in the circumferential direction, the notch between the ridges 23d becomes a drain groove, and the upper end of the frame 23 is formed. This is advantageous in preventing hot water from remaining at the opening window.

By the way, in order to control the upper limit stop position and the lower limit stop position when moving the slide shaft 13 of the driving means in the vertical direction, a magnet 36 is fixed to the lower end side of the slide shaft 13. Proximity sensors 37 and 38 such as Hall elements are separately provided at required upper and lower positions on the inner peripheral surface of the cup 24. Magnet 3
6 is stopped by the guide bar 15 and
Up and down movement is guided.

Next, an installation mode of the operation device 5 will be described. The operating device 5 of this embodiment uses the coil spring 29 at the time of installation. The reason is that the bathtub 1 on which the operation device 5 is to be installed has a thickness of the flange 1a depending on the specification as shown by a solid line and a virtual line in FIG.
Since the size may differ, the thickness of the frame 23 and the upper case 21 of the operating device 5 can be mounted without any change without changing the specifications of the frame 23 regardless of the thickness.

First, with the coil spring 29 fitted on the outer periphery of the large diameter portion 21b of the upper case 21, the upper case 21 is inserted into the through hole 1 provided in the flange 1a of the bathtub 1.
b is fitted from below the flange 1a of the bathtub 1 so as to have a gap. At this time, the lower end of the coil spring 29 faces the step 21d between the large diameter portion 21b and the flange 21c of the upper case 21, and the upper end of the coil spring 29 faces the lower surface of the flange 1a of the bathtub 1, respectively. Be abutted.

In this state, the upper case 21 and the bathtub 1
After inserting the frame 23 from above the flange 1a of the bathtub 1 into the gap between the flange 1a and the through hole 1b,
By turning the frame 23, the frame 23 is screwed into the small diameter portion 21 a of the upper case 21 to be joined. As a result, the coil spring 29 received by the upper case 21 and having the upper end abutting against the lower surface of the flange 1a of the bathtub 1 is in a compressed state. 23c is pressed against the periphery of the through hole 1b on the upper surface of the flange 1a of the bathtub 1. At this time, in the upper case 21, the step between the small diameter portion 21a and the large diameter portion 21b is not in contact with the flange 1a of the bathtub 1. In addition,
It is not necessary to use the coil spring 29, but in that case,
In the upper case 21, the step between the small diameter portion 21 a and the large diameter portion 21 b comes into direct contact with the flange 1 a of the bathtub 1, and eventually the outward flange 23 of the frame 23 is formed.
The flange 1a of the bathtub 1 is sandwiched from above and below by the c and the step of the upper case 21.

As described above, while the outward flange 23c of the frame 23 is directly brought into contact with the upper surface of the flange 1a of the bathtub 1, the upper case 21 is connected to the coil spring 29 with the lower surface of the flange 1a of the bathtub 1. , The flange 1a of the bathtub 1 is sandwiched between the frame 23 and the coil spring 29 attached to the upper case 21. As a result, the entire operation device 5 is attached to the flange 1a of the bathtub 1 in a suspended state.

Incidentally, if the thickness of the flange 1a of the bathtub 1 is thick as shown by the solid line in FIG.
Increases the compression amount of the small diameter portion 21a in the upper case 21.
From the step between the large diameter portion 21b and the flange 1a of the bathtub 1
When the thickness of the flange 1a of the bathtub 1 is small as shown by the imaginary line in FIG.
The amount of compression of the coil spring 29 is reduced, and the bathtub 1 is moved from the step between the small diameter portion 21a and the large diameter portion 21b in the upper case 21.
The gap to the lower surface of the flange 1a increases. Thus, the coil spring 29 absorbs the thickness of the flange 1 a of the bathtub 1.

With the configuration as described above, when the operating device 5 is installed, the frame 23 is attached to the flange 1 a of the bathtub 1.
Can be mounted from above, so that the operator does not have to take an unreasonable posture as in the conventional example, and can work easily. If the working posture can be made to be a natural posture without difficulty, when the worker mounts the frame 23, the worker sees marks and characters written on the circular thin plate 35 of the upper case 21 from directly above. Therefore, it is possible to easily position these marks and characters in a predetermined direction.

The flange 1a of the bathtub 1 is not simply sandwiched between the outward flange 23c of the frame 23 and the upper case 21, but a coil spring 29 is interposed between the upper case 21 and the flange 1a of the bathtub 1. Therefore, even when the thickness of the flange 1a differs depending on the type of the bathtub 1, the operation device 5 can be attached, and the versatility is excellent. In this case, only the degree of compression of the coil spring 29 is changed according to the thickness of the flange 1a of the bathtub 1, and the amount of tightening of the frame 23 with respect to the upper case 21 is always constant. It is excellent in that the workability is improved.

The upper case 21 is connected to the flange 1 of the bathtub 1.
The non-contact with the lower surface of “a” has the following effects. That is, when the bathtub 1 is manufactured using FRP or the like, the lower surface of the flange 1a is irregularly uneven.
When a is sandwiched directly between the case and the frame as in the conventional example, there is a possibility that the frame may be attached in an obliquely raised state due to irregularities on the lower surface of the flange 1a. However, as in the above embodiment, the coil spring 2
In the case of using the structure 9, the coil spring 29 absorbs the irregularities, so that the above-described problem can be avoided.

It should be noted that the present invention is not limited to only the above embodiment, and various applications and modifications are conceivable.

(1) In the above embodiment, the upper opening window of the frame 23 can be formed in a circular shape as shown in FIGS. In this case, when the frame 23 is connected to the upper case 21, even if the frame 23 is not positioned in the circumferential direction, the marks and characters of the circular thin plate 35 of the upper case 21 are always exposed from the upper end opening window of the frame 23. Therefore, when the frame 23 is connected to the upper case 21, there is no need to devise any means for positioning and fixing the frame 23 in the circumferential direction, which is advantageous. In this case, frame 23
Ridge 23 continuous in a ring shape around the outer periphery of the upper opening window
However, as described in the above-described embodiment, at least one circumferential position of the raised portion 23d is cut out so as to be flush with or lower than the upper end surface of the upper case 21, and the drainage groove is formed. You can also.

(2) In the above embodiment, the upper case 2
As shown in FIG. 9, the connection between the frame 1 and the frame 23 can be made by engaging concave and convex portions. That is, at least two locations on the outer circumference of the small diameter portion 21a of the upper case 21 are provided with L-shaped concave grooves 21f, and at least two circumferences of the inner circumference of the cylindrical portion 23a of the frame 23 are provided.
Protrusions 23e are provided at three locations. And
The frame 23 is inserted into a gap between the upper case 21 and the through hole 1b in the flange 1a of the bathtub 1, and
Is inserted into the vertical groove of the concave groove 21f of the upper case 21, and then the frame 23 is pushed downward, and then the frame 23 is turned in one of the circumferential directions, so that the convex portion 23e of the frame 23 is The upper case 21 is fitted into a lateral groove of the concave groove 21f. Thereby, the frame 23 can be connected to the upper case 21. In this example, since the frame 23 can always be attached to the upper case 21 while being positioned in the circumferential direction, the marks and characters of the circular thin plate 35 of the upper case 21 are reliably exposed from the upper end opening of the frame 23. This is advantageous in making it possible.

(3) In the above embodiment, the operating device 5 is installed on the flange 1a of the bathtub 1, but may be installed on a peripheral portion of the bathtub 1, for example, on the top plate 1e of the bathroom counter 1d.

(4) The operating device 5 can be applied to, for example, an operating device of a jet bath device, although not described in detail, in addition to the drain plug unit 3.

[0060]

According to the first aspect of the present invention, the case is applied from the back side of the substrate, and the frame is joined to the case from the front side of the substrate, so that the frame is sandwiched between the frame and the case. Since the frame can be attached to and detached from the front surface side of the substrate, the worker can work without taking an unreasonable posture, and the workability is improved. In addition, since it is possible to work while observing the mounting state from the front side of the board, particularly when the bathroom operation device is mounted, it is easy to work when it is necessary to position the operation surface of the frame or the case in a specific direction. Workability is improved.

According to the second aspect of the present invention, the case is applied from below the bathtub flange, and the frame is connected to the case from above the bathtub flange, so that the bathtub flange is sandwiched between the frame and the case. Since the frame can be detached from the bathtub flange, the worker can work without taking an unreasonable posture, and the workability is improved. Moreover, especially when installing the bathroom operating device,
