DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control device used for a cleaning device for cleaning and drying a local part of a body after stool.

[0002]

2. Description of the Related Art A remote control device for a washing device of this type, which is mainly used for a Western-style toilet, is provided with a transmitting device and a receiving device, and the transmitting device is usually installed at an appropriate position on the inner wall surface of the toilet. , The receiving device is installed on the upper surface of the cleaning device. The transmitting device is usually installed at a position higher than or approximately at the same height as the receiving device. In this case, if the transmission and reception of the optical signal is in the horizontal direction including the obliquely downward direction, it becomes difficult to receive the optical signal depending on the installation positions of the transmission device and the reception device, and the installation position of the transmission device is particularly restricted. That is,
As the infrared light emitting element used as the optical signal transmitting means and the infrared light receiving element used as the optical signal receiving means are generally general-purpose elements having a single directivity, the transmitting device and the infrared transmitting element are opposed to each other. It is necessary to install a receiving device. However, if the transmitter is installed on the left, right, or front wall in the toilet, the light signal cannot be received if the user's body or limb in the cleaning device or stool becomes an obstacle to the light signal. Therefore, the cleaning device cannot be operated. Therefore, it is necessary to install such a cleaning device and a place where a human body becomes an obstacle.

For example, as shown in FIG. 12, a transmission device 4 is installed on a left side wall 3 when viewed from a user 2 who sits on a toilet 1 in a toilet, and a central portion of an upper surface of a cleaning device 5 disposed behind the toilet 1. If the receiving device 6 is installed in the user, the body and limbs of the user 2 become obstacles, and the receiving device 6 cannot receive the optical signal 7. The same applies to the case where the transmitting device 4 is installed not only on the left side wall 3 but also on the right side wall 8 and the front wall 9.

In order to solve the above problem, for example, a plurality of infrared light emitting elements are installed in the transmitting device 4 at an angle so as to point in different directions, and the plurality of infrared light emitting devices are similarly installed in the receiving device 6. If the light receiving elements are installed at an angle so as to be directed in different directions, the light signal transmitted from the infrared light emitting element can be received directly or on the wall by the receiving device 6. Thus, the degree of freedom with respect to the installation positions of the transmitting device 4 and the receiving device 6 is increased, and the reception can be performed reliably.

[0005] However, in order to be able to receive the signal regardless of whether it is installed on the left side wall 3, the right side wall 8, or the front wall 9, the optical signal is obliquely downward at the front, obliquely downward at the front, and obliquely downward at the front. Since transmission is required, at least three infrared light emitting elements and three infrared light receiving elements are required. Therefore,
There is a problem that the number of components of the element increases and the manufacturing cost increases. Also, the number of driver circuits for driving the infrared light emitting element is increased, so that power consumption is increased. In the case of battery driving, the battery is quickly consumed and is not economical. In addition, an increase in the number of driver circuits causes radiation noise due to a large current, which affects peripheral devices such as a television and a radio. Further, when mounting the infrared light emitting element and the infrared light receiving element on the printed wiring board, it is necessary to mount the infrared light emitting element and the infrared light receiving element at an angle, so that a jig or the like is required. In addition, there are many problems such as an increase in the mounting area on the printed wiring board and the layout of the circuit pattern, and an increase in the size and cost of the printed wiring board itself.

In order to solve the above problem, for example, an optical remote controller for a sanitary washing device disclosed in Japanese Patent Application Laid-Open No. 1-50730 is known. This optical remote control device has an optical signal transmitting means installed on the inner wall surface of the toilet, transmits an optical signal from the optical signal transmitting means toward the ceiling of the toilet, and transmits the optical signal reflected on the ceiling to the upper surface side of the cleaning device. It is configured to be received by the provided optical signal receiving means.

In such an optical remote control device, a vertical transmission / reception system is adopted, so that the cleaning device and the human body hardly become obstacles as compared with the above-mentioned horizontal transmission / reception system. Even if there is only one infrared light receiving element each, it can reliably receive, and remote control control means can be installed anywhere on the inner wall surface of the toilet as long as the user can operate it. There is an advantage that there is no restriction on the position.

[0008]

However, the above-mentioned conventional optical remote controller for a sanitary washing device employs a vertical transmission / reception system utilizing reflection from a ceiling, so that the optical path length of an optical signal is long. Further, since a part of the optical signal is absorbed by the ceiling, the loss is large, and therefore, there is a problem that a large output power is required as compared with the horizontal transmission / reception method. In particular, if the ceiling material itself is a material that easily absorbs infrared rays or is a black-and-white material, it is necessary to replace the ceiling material itself with the installation of the optical remote control device. In addition, the lighting device such as an incandescent light bulb or a fluorescent lamp attached to the ceiling may be a noise source, so that the sensitivity is reduced, particularly in a lighting device using an inverter,
If the operating frequency matches or approximates the cleaning device,
There is a problem that the cleaning device malfunctions.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to enable a cleaning device or a human body to receive an optical signal without causing any obstacles. It is another object of the present invention to provide a low-cost and highly-sensitive remote control device for a cleaning apparatus which enables a horizontal transmission / reception system with a minimum number of infrared light emitting elements and infrared light receiving elements.

[0010]

According to a first aspect of the present invention, there is provided a transmitter for transmitting an optical signal mounted on an inner wall surface of a toilet for controlling the driving of a washing device horizontally or obliquely downward. And a receiving device attached to the cleaning device for receiving the optical signal, wherein at least one of the transmitting device and the receiving device is provided with a hologram element that transmits the optical signal.

In the first aspect, the hologram element manufactured by the laser hologram is inexpensive and thin, and the light diffusion angle can be arbitrarily set at the time of manufacture.
Therefore, when a hologram element having a light diffusion angle corresponding to the installation position of the transmitting device and the receiving device is used, even if the optical signal transmitting unit and the optical signal receiving unit each have a single directivity, Also, despite the horizontal transmission / reception, the cleaning device and the human body can reliably receive the optical signal directly or reflected on the wall without causing an obstacle,
The degree of freedom of wall installation is expanded.

According to a second aspect, in the first aspect,
The hologram element is characterized in that the hologram element is constituted by a combination of a plurality of hologram films which are variably disposed with respect to a transmission device or a reception device and have different light diffusion angles.

In the second aspect of the present invention, the receiving sensitivity varies depending on the installation location of the transmitting device and the environmental change of the toilet, and the hologram film having the light diffusion angle at which the receiving sensitivity becomes the highest is selected and used. Can be reliably received, and the degree of freedom of wall installation is expanded. As a structure in which the hologram film can be changed freely, the hologram film may be provided so as to be movable or rotatable.

According to a third aspect, in the first or second aspect, a prism for changing an optical path of an optical signal is provided.

In the third invention, the prism changes the optical path by refracting the optical signal when the optical signal is incident. Therefore, when the prism is provided in the transmitting device, the diffusion direction of the optical signal by the hologram element is changed, and when the prism is provided in the receiving device, the focal position of the optical signal is changed. Thereby, the degree of freedom of the installation positions of the transmitting device and the receiving device is further expanded.

According to a fourth aspect of the present invention, the first, second or third aspect is provided.
In the invention, the hologram element is colored in a smoke color.

In the fourth invention, the hologram element has a blinding function for preventing the inside from being visually recognized, in addition to a diffusing / light collecting function. Therefore, there is no need to separately manufacture and provide a blind plate.

Signal 3
When the receiving device 24 receives 0, the cleaning nozzle is driven to project below the toilet seat 18, and the cleaning water is ejected upward from the ejection port of the washing nozzle. Further, when the drying switch button 27 is operated after the washing, the dryer is driven to blow hot air to dry the local part, and when the stop switch button 28 is operated, the drying machine returns to the original state. .

The transmitting device 23 is installed in a remote control installation area (shaded area in FIG. 5) 31 which can be operated by the user 2 on the left side wall 13 in the toilet 10, for example.
On the other hand, the receiving device 24 is the housing 3 of the cleaning device 21.
2 is embedded in the right end upper surface 32a.

Further, a transmitting device 23 and a receiving device 24
Will be described in detail below. 2 and 3, the transmission device 23 is a horizontally long thin box-type having a front case 33A and a rear case 33B fixed in the remote control installation area 31 of the left side wall 13 with screws, double-sided adhesive tape, or the like. A case 33 is provided. Inside the case 33,

The printed wiring board 35 has the infrared light emitting element 34 mounted thereon and outputs a modulation output in response to the operation of the various switches, and a carrier oscillation circuit (modulated by the output of the modulation circuit). All of them are not shown).

On the front side of the case 33, the various switch buttons 26, 27, 28 and the hologram element 3
6, a top sheet 37, and a blind plate 38 are provided. For this reason, an opening 39 is formed in a portion corresponding to the infrared light emitting element 34 on the front surface of the front case 33A, and the opening 39 is formed in the hologram element 3.
6 and a blind plate 38. The hologram element 36 is formed in a film shape by a well-known laser hologram technique described later. The blind plate 38 is used to prevent the inside of the case from being viewed, and is made of a synthetic resin such as an acrylic resin, and has a smoke-colored film having a high transmittance for the optical signal 30 formed on the surface thereof. This is why it is commonly called the smoke top.
Note that such a smoke top is the same as that conventionally used widely in televisions, remote control devices for heating equipment, and the like.

It is desirable that the remote control installation area 31 in which the transmission device 23 is installed is an area where the user 2 can easily operate the transmission device 23 easily while sitting on the toilet seat 18. For this reason, the optimal remote control installation area 31 is naturally limited, and as shown in FIG. 5, at the wall surface right beside the user 2 sitting on the toilet seat 18, the left arm is vertically lowered and the front is centered on the base. Is set in a rotation area (shaded area) when the camera is turned until it is substantially horizontal.
The remote control installation area 40 on the right side wall 14 is a left-right symmetrical area with respect to the remote control installation area 31. When the distance between the front wall 15 and the toilet body 17 is small and the hand of the user 2 reaches the front wall 15, the transmitting device 23 may be installed on the front wall 15.

The infrared light emitting element 34 is a general-purpose infrared light emitting element having a single directivity, and is mounted substantially perpendicular to the printed wiring board 35. Further, the printed wiring board 35 is incorporated in the case 33 substantially vertically. Therefore, the optical signal 3 transmitted from the infrared light emitting element 34
The direction of 0 is substantially horizontal and forward of the case 33.

In FIG. 4, the receiving device 24 includes a case 41 embedded and installed on the upper surface of the cleaning device 21.
A plurality of display light-emitting elements (LEDs) 42 disposed in the case 41 for displaying various operation states such as cleaning and drying, power on / off, timer on / off, and the like; An infrared light receiving element 43 for receiving the optical signal 30 from the light emitting element 34, a printed wiring board 44, a translucent surface sheet 45 covering the surface of the case 41, and an infrared light receiving element 43 for condensing the optical signal 30 A hologram element 46 leading to
The hologram element 46 is provided with a smoke top 47 and the like.

The printed wiring board 44 is installed horizontally in the case 41, and the LED 42 and the infrared light receiving element 43 are mounted on the upper surface side. Further, an amplification circuit (not shown) for amplifying the output of the infrared light receiving element 43, a reception signal decoding circuit for decoding the sign of the output of the amplification circuit, and the like are formed. The output from the reception signal decoding circuit forms the cleaning device. The drive of the LED 21 is controlled, and the LED 42 is selectively turned on.

An opening 48 is provided at a location on the surface of the case 41 corresponding to each of the LEDs 42 and the infrared light receiving element 43.
49 are formed, the opening 48 is covered by the topsheet 45, and the opening 49 is covered by the hologram element 46 and the smoke top 47. The smoke top 47 is the smoke top 38 of the transmitting device 23.
It is formed identically.

In FIG. 1, a housing 32 of the cleaning device 21 is formed in a U-shape in plan view so as to surround the toilet body 17 from behind. Therefore, the receiving device 24
Is embedded on the right end upper surface 32 a is located on the right side of the toilet body 17. Therefore, the receiving device 2
When viewed from the remote control installation area 31, the right end upper surface 32a in which the embedded device 4 is embedded is shadowed by the user 2 in the stool, so that the reception device 24 directly receives the optical signal 30 from the transmission device 23. It is a difficult part.

Therefore, in the present invention, the hologram elements 36 and 46 manufactured by the laser hologram technique are used.
Are provided in the transmitting device 23 and the receiving device 24, and the optical signal 30 is diffused and condensed by these components, so that the
Is ensured to be received. The hologram elements 36 and 46 are exactly the same, and the hologram element 36 used on the transmitting device 23 side is used as a diffuser for diffusing the optical signal 30. On the other hand, the hologram element 46 used on the receiving device 24 side is used as a condenser lens that condenses the optical signal 30 and guides it to the infrared light receiving element 43.

The laser hologram technique is conventionally known as described in, for example, JP-A-4-342624, JP-A-5-341703, JP-A-9-292508. A method of manufacturing the hologram elements 36 and 46 will be schematically described with reference to FIG.
a laser light source such as an e-laser;
3 is a lens and 54 is a hologram dry plate. The laser light (divergent light) 55 emitted from the laser light source 50 is reflected by the reflectors 51 and 52, and the two laser lights 55
a and 55b are incident on the hologram dry plate 54, and the hologram dry plate 54 is exposed. The exposure is performed by moving the hologram dry plate 54 in the horizontal direction within the range to be exposed. As a result, interference fringes of the two laser beams 55a and 55b are recorded on the surface of the hologram dry plate 54 to form a diffraction grating. Next, the exposed hologram plate 5
4. Make a mold based on 4. The hologram elements 36 and 46 are manufactured by injection molding using this mold. In such hologram elements 36 and 46,
When light is incident at an angle equal to that of the laser light 55b, this light is diffracted and diffused in the traveling direction of the laser light 55a.

When the hologram elements 36 and 46 are manufactured, the lens 53 is replaced with one having a different focal length, so that the light diffusion angle θ of the hologram elements 36 and 46 is changed.
(FIG. 6) can be set arbitrarily. The production by the laser hologram is performed by using the hologram elements 36 and 46.
There is an advantage that the film itself can be formed in a thin film shape, and it is easy to manufacture and inexpensive. Further, when the hologram elements 34 and 46 are made of acrylic resin and colored in smoke, the smoke tops 38 and 47 covering the openings 39 and 49 of the cases 33 and 41 are also provided in order to also have a function as a smoke top. It can be omitted.

As described above, the receiving device 24 is the transmitting device 2
In this embodiment, the optical signal 30 is diffused over a wide range using the hologram element 36 having a large light diffusion angle θ because the optical signal 30 from the right side wall 14 is not easily received. An optical signal 30 reflected on the front wall 15 or the rear wall 16 is received by the receiving device 24.

However, the remote control installation area 4 on the right side wall 14
When the transmitting device 23 is installed at 0, since the cleaning device 21 and the user 2 do not directly become obstacles, the hologram element 36 having a small light diffusion angle θ may be used to directly receive the optical signal 30. . In addition, the front wall 15 is
When the transmitting device 23 can be installed close to the hologram element 36, if the installation position is on the receiving device 24 side, the hologram element 36 having a small light diffusion angle θ is used because the user 2 does not become an obstacle. When the user 2 becomes an obstacle on the side opposite to the receiving device 24 side, the hologram elements 36 and 46 having a large light diffusion angle θ are used to receive the optical signal reflected on the wall surface. I just need. Note that the hologram element 46 of the receiving device 24 does not necessarily have to have the same light diffusion angle θ as the hologram element 36 on the transmission side.

As described above, the remote control device 22 according to the present invention is used.
Uses the hologram elements 36 and 46 manufactured by the laser hologram technology, so that the hologram element itself can be easily and inexpensively manufactured. Further, as compared with the conventional device, the transmission and reception of the optical signal 30 is more reliable and a horizontal transmission / reception system is enabled, and a low-cost and high-sensitivity device can be obtained. That is, when the hologram elements 36 and 46 having the light diffusion angle θ corresponding to the installation positions of the transmission device 23 and the reception device 24 are selected and used, the infrared light emitting element 34 and the infrared light receiving Even if the plurality of elements 43 are not provided, the body and limbs of the cleaning device 21 and the user 2 can reliably receive the optical signal 30 without becoming an obstacle, so that a low-cost and highly-sensitive remote control device is obtained. be able to. Therefore, the cleaning device 21
Can be reliably driven.

In the horizontal transmission / reception system, the distance between the walls is shorter than in the conventional vertical transmission / reception system based on ceiling reflection, so that the loss of the optical signal 30 due to the wall reflection is small and the transmission / reception system is installed on the ceiling 12. It is less affected by disturbance due to the illuminating device 60 and the sensitivity can be improved.

Further, since there is no need to provide a plurality of infrared light emitting elements 34 and infrared light receiving elements 43, the number of components can be reduced and power consumption can be reduced. Can be. Furthermore, only one driver circuit is required, the mounting area on the printed wiring boards 35 and 44 and the layout of circuit patterns are small, the design is easy, and the size and cost of the printed wiring boards 35 and 44 can be reduced.

In addition, since the infrared light emitting element 34 and the infrared light receiving element 43 can be mounted substantially perpendicular to the printed wiring boards 35 and 44, no jig or the like is required, and the mounting work of these elements is easy. is there.

Here, a prism 63 may be arranged between the infrared light emitting element 34 and the hologram element 36 as shown in FIG. The prism 63 has a plurality of small triangular protrusions 63a arranged side by side on the surface. When such a prism 63 is arranged, when the optical signal 30 enters the prism 63, it is refracted by the slope of the protruding body 63a and the optical axis is tilted, whereby the optical signal 30 is diffused by the hologram element 36. The direction can be changed to an oblique direction (obliquely downward, obliquely right or obliquely leftward). It is needless to say that the prism 63 may be similarly arranged not only on the light emitting device 23 side but also on the light receiving device 24 side. Further, the prism 63 may be arranged in front of the hologram element 34.

When it is desired to diffuse the optical signal 30 in an oblique direction,
Although it is necessary to mount the infrared light emitting element 34 at a tilt in the diffusion direction with respect to the printed wiring board 35, when the optical signal 30 is refracted using the prism 63 as shown in FIG. As shown, the light is diffused diagonally rightward, so that the infrared light emitting element 34 can be mounted substantially perpendicularly to the printed wiring board 35. If the light is diffused in an oblique direction depending on the installation position, height, and the like of the transmission device 23 and the reception device 24, the reception of the optical signal 30 becomes easy, and the transmission can be performed with a small output power.

As shown in FIG. 8, a circular convex portion 65 and an annular concave portion 66 surrounding the periphery of the convex portion 65 are formed on the surface of the hologram element 46 used in the receiver 24, and the hologram element 46 is formed. It is difficult to transmit and condense light 67 from above, which enters substantially perpendicularly to the light source, and it is possible to transmit and condense the optical signal 30 incident from an oblique direction. , And the reliability of reception can be improved.

FIG. 9 is a sectional view showing another embodiment of the present invention. In this embodiment, a hologram element 71 is disposed in a concave portion 70 provided on the surface of a case 33 of a transmitting device 23 so as to be movable in the left-right direction in the figure, and is covered by a surface plate 72. Further, a small through hole 73 is provided in the center of the bottom surface of the recess 70, and the infrared light emitting element 3

71B and 71C are the hologram elements 36 and 46 described above.
Each is manufactured by the laser hologram technology in the same manner as the above.

The surface plate 72 functions as a smoke top by being colored in smoke, and has an opening 74 and a slit 75. The opening 74 is provided in the through hole 73.
, And have substantially the same center.
The slit 75 is formed to be long in the moving direction of the hologram element 71, and has a length such that one end communicates with the opening 74 and the other end reaches the outer periphery of the concave portion 70. An operation pin 77 as an operation section protruding from the surface of the hologram element 71 is slidably inserted through the slit 75.

In such a structure, the operation pin 7 is
7 is moved to the left or right along the slit 75, the three hologram films 71A, 71B, 71C
Can be located between the infrared light emitting element 34 and the opening 74, whereby the light diffusion angle of the hologram element 71 can be switched. For example, the hologram film 71A is
When the hologram film 71B is positioned at the opening 74, the light diffusion angle is θ2. As described above, any one of the three hologram films 71A, 71B, and 71C having different light diffusion angles is selected according to the installation location of the transmission device 23 and the reception device 24, and the light diffusion angle as the hologram element 71 is selected. When the remote control device is installed, the environment of the toilet (wallpaper, shape, size due to modification, renovation, installation of heating equipment, etc.) becomes possible after the remote control device is installed. Even if the hologram film is changed, it is possible to obtain the reception sensitivity suitable for the toilet environment by selecting the hologram film having the light diffusion angle having the highest reception sensitivity among the three hologram films 71A, 71B, and 71C. it can.

FIGS. 10A and 10B are a sectional view and a front view of a hologram element showing still another embodiment of the present invention. In this embodiment, approximately 1 /
The light diffusion angles formed in an arc shape of No. 4 are θ1, θ2, θ3

The hologram film is freely pivoted so that any one of the four hologram films 80A to 80D selectively faces the opening 74 of the surface plate 72.

Further, the two prisms 63A and 63B are incorporated so that the directions of the projections 63a juxtaposed on the surface are opposite, so that when one of the prisms 63A is used, the optical signal 30 is changed to ( b) The light is refracted diagonally to the left as shown in the figure, and when the other prism 63B is used, the light is refracted diagonally to the right as shown in FIG. An opening 74 and two slits 75A and 75B are formed in the surface plate 72. The prism 63

It is not specified, and may be used for at least one of them, for example, only the transmission device 23.

[0050]

As described above, according to the remote control apparatus of the cleaning apparatus according to the present invention, since the hologram element manufactured by the laser hologram technique is used, the cleaning apparatus and the human body do not become obstacles and can be transmitted from the transmitting apparatus. The transmitted optical signal can be reliably received by the receiving device directly or by reflecting the optical signal on the wall surface. Therefore, transmission and reception in the horizontal direction are possible, and the reception sensitivity can be improved with less loss compared to the vertical method using ceiling reflection, and the influence of disturbance by the lighting device installed on the ceiling is small. In addition, the cleaning device can be reliably operated. Further, there is no need to provide a plurality of infrared light emitting elements and light receiving elements, so that power consumption can be reduced, and when a battery is used, the life of the battery can be extended.

Also, since the mounting area of the infrared transmitting and receiving means on the printed wiring board is small and the driver circuit can be integrated into one, the design of the circuit pattern is small and the radiation noise is suppressed by a thick and short pattern. Can be. Therefore, the printed wiring board can be manufactured easily and inexpensively, and the size can be reduced.

The hologram element can be manufactured thinly, easily and inexpensively.

In the present invention, the optical path of the optical signal is changed by the prism, so that the receiving sensitivity can be improved depending on the installation position, height, etc. of the transmitting / receiving device. In addition, since the hologram element is configured to be movable by a combination of a plurality of hologram films having different light diffusion angles, when the environment of the toilet is changed, by selecting a hologram film having a light diffusion angle at which the sensitivity becomes highest, the It is possible to obtain reception sensitivity suitable for the toilet environment.
