Description

The present invention relates to a toilet equipment system, and more particularly to a toilet equipment system that uses a remote control device that controls electronic devices such as washing toilet seat devices by radio wave signals.

  In recent years, a toilet seat apparatus having various functions such as a cleaning function, a drying function, and a deodorizing function has been attached to a toilet bowl. These functions are activated when the user presses the operation buttons collected on the operation panel of the flush toilet seat device.

  Conventionally, many of the operation panels are conventionally arranged on the washing toilet seat device, but recently, the operation panel having a remote control device separately from the washing toilet seat device main body has become mainstream. Then, when a user operates an operation button arranged on the remote control device, a control signal from the remote control device is sent to the cleaning toilet seat device body by infrared rays, and the control signal is received by the cleaning toilet seat device body that has received the signal. The control according to is performed.

  However, in such a remote control device, since infrared communication is performed by an infrared output LED, power consumption by the communication is large.

  Moreover, in communication using light such as infrared rays, communication may not be possible due to the relationship with the direction of the remote control device or the presence of obstacles, so a plurality of LEDs for infrared output are directed in a plurality of directions. There is a problem that the power consumption is further increased due to the need to arrange them.

  Therefore, a battery having a large capacity has to be used, and it has been difficult to reduce the size of the remote control device.

  In order to solve the problem of infrared communication as described above, a remote control device that controls an electronic device has been proposed that uses radio communication using radio waves (for example, see Patent Document 1).

Such wireless communication using radio waves can reduce power consumption compared to infrared communication, and has the great advantage that it is not necessary to consider the direction of the remote control and the presence of obstacles as much as infrared communication.

  However, when a remote control device that performs radio communication using radio waves as described in Patent Document 1 described above is applied to a toilet equipment system such as a toilet seat device, the following problems occur.

  The remote control device of the cleaning toilet seat device is generally detachably attached to the wall surface in the vicinity of the toilet bowl where the cleaning toilet seat device is installed. However, depending on the toilet booth where the cleaning toilet seat device is installed, the wall surface may be attached to a PVC steel plate. There is something to do. For example, a unit bath with a toilet in a business hotel or the like.

  When the remote control device is attached to the wall surface formed of such a PVC steel plate, the remote control device is disposed in the vicinity of the PVC steel plate. Inductance is generated.

  In general, such stray capacitance and mutual inductance are small, and the control circuit and the like are hardly affected.

  However, in a radio circuit, there are often a relatively small value of a capacitor element, an inductance element, or a portion having a high impedance, and the influence of this stray capacitance and mutual inductance cannot be ignored.

  That is, the stray capacitance and mutual inductance greatly affect the frequency and intensity (output level) of radio waves generated from the radio circuit.

  For this reason, when a remote control device is attached to a wall surface having a conductive member such as a vinyl chloride steel plate, phenomena such as frequency shift of the radio wave output by the radio circuit of the remote control device and a decrease in output level occur, and the radio wave output from this remote control device There arises a problem that the cleaning toilet seat device cannot receive the signal.

  As a solution to such a problem, although a method of adjusting the radio circuit after installing the remote control device on the wall surface having the conductive member can be considered, the frequency deviation of radio waves and the output level decrease due to the influence of stray capacitance and mutual inductance Since it varies greatly depending on the installation environment of the remote control device, that is, the distance between the remote control device and the conductive member, the type of the conductive member, etc., the adjustment is not easy and complicated.

  Moreover, in addition to being used in a state where the remote control device is attached to the wall surface, the remote control device is often used by being detached from the wall surface, and even if the radio circuit is adjusted with the remote control device attached to the wall surface, When removed from the remote control device, the remote control device is released from the effects of stray capacitance and mutual inductance, and the frequency and output of the adjusted radio wave change. Therefore, the radio wave output from the remote control device cannot be received by the washing toilet seat device, or the output level of the radio wave exceeds a specified value.

  Accordingly, an object of the present invention is to provide a remote control device that stabilizes the frequency and level of the output radio wave regardless of whether or not the above-described conductive member is present on the wall to which the remote control device is attached. .

The conductive member has a frequency of the radio signal output from the wireless circuit in which a stray capacitance or mutual inductance generated between the conductive circuit and the wireless circuit is generated. Since the influence was within the range giving, you become possible to reduce the influence of the radio circuit by stray capacitance and mutual inductance generated between a wall surface of the conductive member and the remote control device.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a view showing a cleaning toilet seat system comprising a cleaning toilet seat device according to an embodiment of the present invention installed in a toilet booth and a remote control device for controlling the same, and FIG. 2 is a side view of the remote control device according to the embodiment of the present invention. 3 is a block diagram showing the configuration of the remote control device according to the embodiment of the present invention. FIG. 4 is a front view of the remote control device according to the embodiment of the present invention.

  As shown in FIG. 1, the cleaning toilet seat system S in the embodiment of the present invention includes a cleaning toilet seat device 1 and a remote control device 2 installed in a toilet booth.

  The cleaning toilet seat device 1 is installed on the toilet 3 and has a cleaning toilet seat device body 4 having a control unit for controlling various functions, and a toilet seat 5 rotatably connected to the cleaning toilet seat device body 4. A toilet lid 6 is rotatably connected to the cleaning toilet seat device body 4.

  The cleaning toilet seat device body 4 has a main body control unit (not shown) for operating various functions such as a cleaning function, a drying function, a deodorizing function, and a toilet seat heat retaining function, and further receives a radio wave signal transmitted from the remote control device 2. A receiving antenna and a radio wave receiver are provided.

  When a control signal output as a radio wave from the remote control device 2 (hereinafter referred to as “radio wave signal”) is received by the radio wave receiving unit via the receiving antenna, the main body control unit performs control according to the radio signal. Is supposed to do.

  On the other hand, as shown in FIG. 2, the remote control device 2 is a toilet booth wall surface 10 in which a locking portion 21 provided on the rear surface of the housing has a conductive member such as a steel plate printed or bonded with polyvinyl chloride or polyester resin. It is detachably attached to the wall surface 10 by engaging with the locking portion 71 of the holder 7 attached to the wall 10. Instead of attaching to the wall surface 10 via the holder 7, a locking member (not shown) is directly attached to the wall surface 10, and the locking portion 21 of the remote control device 2 is engaged with this locking member. May be.

  Further, as shown in FIG. 3, the remote control device 2 includes various switch units 22 such as various cleaning function buttons, a drying button, a cleaning power control button, and a massage button, and a display unit 23 for displaying time and control contents. The storage unit 24 stores various setting contents, the wireless circuit 25 transmits a control signal as a radio wave signal to the cleaning toilet seat main body 4, and the control unit 26 that controls the entire remote control device 2.

  Here, the radio circuit 25 includes a modulation circuit 27, an amplifier circuit 28, a transmitting antenna 29, and the like. The modulation circuit 27 and the amplification circuit 28 are combined to form a wireless transmission circuit.

  The modulation circuit 27 generates a control signal input from the control unit 26 based on a predetermined frequency signal (for example, 44.57 MHz) generated by an internal oscillation circuit 27a (not shown). Is a circuit having a function of passing only a predetermined high-order harmonic component (for example, the 312 MHz band of the seventh-order harmonic component) through an internal band filter circuit 27c (not shown).

  The amplifier circuit 28 is a circuit that amplifies the power of the signal output from the modulation circuit 27 and includes a matching circuit 28a (not shown) with a transmitting antenna 29 described later.

  The transmitting antenna 29 is an antenna that outputs the amplified signal output from the amplifier circuit 28 to the cleaning toilet seat device body 4 as a radio wave signal.

  Note that the radio circuit 25 of the remote control device 2 varies in frequency and output level of the radio wave signal to be output due to variations in components constituting the circuit when the remote control device 2 is mass-produced.

  Therefore, a trimmer capacitor is provided in each of the band filter circuit 27c and the matching circuit 28a in order to adjust the frequency and output level of the radio signal within a certain range.

  Further, as shown in FIG. 4, the remote control device 2 has a substantially box-like shape, and various switches 22 and a display 23 are provided as operation panels on the front surface of the casing.

  When the various switch units 22 of the remote control device 2 are operated by the user of the cleaning toilet seat device 1, the control unit 26 detects the operation and sends a control signal according to the button type of the operated switch unit 22 to the radio circuit. To 25. Then, the radio circuit 25 converts the control signal into a high frequency modulation signal, and is transmitted to the cleaning toilet seat apparatus body 4 as a radio wave signal by the transmitting antenna 29.

  The internal structure of the remote control device 2 configured as described above will be specifically described below with reference to the drawings.

  5 is a cross-sectional view of the remote control device according to the embodiment of the present invention (cross-sectional view taken along line AA in FIG. 4), FIG. 6 is a rear view of the remote control device according to the embodiment of the present invention, and FIG. FIG. 8 is an explanatory diagram of stray capacitance of the remote control device according to the embodiment of the present invention, and FIG. 9 is a remote control device according to the embodiment of the present invention. FIG. 10 is a rear view of the remote control device according to the embodiment of the present invention.

  As shown in FIG. 5, the remote control device 2 includes a box-shaped casing 30 including a front cover 31 having an opening through which a button and a display unit are exposed, and a rear cover 32 that faces the wall surface when the wall surface is attached. A substrate 33 and the like that are disposed in the body 30 and are attached to the front cover 31 are provided.

  A switch unit 22 and a display unit 23 are provided on the front surface side (front cover 31 side) of the substrate 33, and a storage unit 24 such as a ROM or a RAM is provided on the rear surface side (back cover 32 side). A wireless circuit 25 and a control unit 26 are provided.

  Further, a conductive member 34 is attached between the radio circuit 25 and the back cover 32 so as to cover the radio circuit 25 on the back surface side of the substrate 33.

  6 and 7 show rear views of the remote control device with the rear cover 32 of the remote control device 2 removed.

  As shown in FIG. 8, the conductive member 34 generates a stray capacitance (C) or a mutual inductance that affects the operation of the wireless circuit 25, so as to generate the wireless circuit 25. Located in the vicinity. Note that it is desirable that the distance between the conductive member 34 and the wireless circuit 25 be as short as possible.

  The conductive member 34 has an area substantially equal to or larger than the area of the radio circuit 25 occupying the back surface of the substrate 33 and is disposed so as to cover the radio circuit 25. That is, the conductive member 34 having an area covering the surface is arranged on the surface where the radio circuit 25 and the back cover 32 face each other. The wireless circuit 25 may be sealed with the conductive member 34 or covered in a state close thereto.

  Further, as the conductive member 34, a metal plate such as aluminum, iron or silicon steel is used, and at least one end thereof is connected to the ground of the electric circuit by soldering or the like.

  By the way, such a circuit whose characteristics are affected by stray capacitance and mutual inductance includes a capacitor element and an inductance element having a relatively small value, and a band-pass filter circuit 27c, a matching circuit 28a, and a transmission circuit having a high impedance portion. An antenna 29 or the like.

  For example, if the band filter circuit 27c is affected, the filtering frequency is shifted, and the output frequency and output level are similarly shifted. Further, when the matching circuit 28a is affected, the impedance is shifted due to the relationship with the transmitting antenna 29, and the output level is lowered.

  As described above, a circuit whose characteristics are affected by stray capacitance and mutual inductance is not the entire radio circuit 25 but only a part thereof.

  Therefore, the conductive member 34 is disposed only in the portion affected by the stray capacitance and the mutual inductance, that is, only in the vicinity of the capacitor element and the inductance element having a relatively small value, or the high impedance portion. The area 34 can be reduced, and the production cost of the remote control device 2 can be reduced.

  As described above, a metal plate such as aluminum or iron has been described as an example of the conductive member 34. However, the wireless circuit 25 portion on the back side of the substrate 33 (particularly, a circuit whose characteristics are affected by stray capacitance and mutual inductance). Alternatively, stray capacitance or mutual inductance may be generated between the conductive paste and the radio circuit 25 by conducting a conductive (silver, copper, etc.) paste in the vicinity thereof. This conductive paste is connected to the circuit ground at one or more locations.

  Alternatively, a substrate (a substrate different from the substrate 33) having a copper foil arranged on one surface may be used as the conductive member 34 so as to cover the wireless circuit 25.

  Furthermore, a multilayer substrate may be used as the substrate 33, and one of the plurality of layers may be a ground layer, and the ground layer may be the conductive member 34. The closer the distance to the ground layer, the greater the stray capacitance and mutual inductance with the ground layer. Therefore, it is desirable that this ground layer be in the vicinity of a layer where characteristics are affected by stray capacitance and mutual inductance.

  By the way, the conductive member 34 is disposed in the vicinity of the wireless circuit 25 so that stray capacitance and mutual inductance that affect the operation of the wireless circuit 25 of the remote control device 2 are generated between the wireless circuit 25 and the wireless circuit 25. Therefore, in the circuit design of the wireless circuit 25, it is necessary to determine the internal constants in consideration of such stray capacitance and mutual inductance.

  However, when the remote control device 2 is mass-produced, variations occur in the characteristics of the conductive member 34, the positions of the conductive member 34 and the wireless circuit 25, and the like.

  Therefore, the radio circuit 25 of the remote control device 2 of the present embodiment is provided with a characteristic adjustment portion such as a trimmer capacitor (VC101 to VC103) that takes into account not only the variation of components as described above but also the stray capacitance and mutual inductance. It has been.

  Moreover, as shown in FIG. 7, the conductive member 34 is provided with openings 34a to 34c through which a driver or the like is passed in order to adjust the characteristic adjustment portions such as the trimmer capacitors VC101 to VC103. Therefore, after the conductive member 34 is attached to the substrate 33, the wireless circuit 25 can be adjusted from this opening, and workability is improved.

  Note that the back cover 32 may be provided with openings 32 a to 32 c (not shown) at positions corresponding to the openings 34 a to 34 c of the conductive member 34. In this way, adjustment components such as the trimmer capacitors VC101 to VC103 can be adjusted through the openings 32a to 32c and the openings 34a to 34c.

  Before and after the remote control device 2 configured as described above is attached to the wall surface 10 having the conductive member, the wireless circuit 25 is connected to the wireless circuit 25 due to stray capacitance and mutual inductance generated between the conductive member of the wall surface 10 and the remote control device 2. The change in impact is greatly compressed.

  That is, the conductive member 34 is provided between the conductive member of the wall surface 10 and the wireless circuit 25 and has an area equal to or larger than the arrangement area of the wireless circuit 25 so as to cover the wireless circuit 25. A stray capacitance or mutual inductance is generated between the conductive member and the conductive member 34. On the other hand, since the conductive member 34 is disposed so as to cover the wireless circuit 25, the generation of stray capacitance and mutual inductance between the wireless circuit 25 and the conductive member of the wall surface 10 is greatly reduced.

  In addition, since the conductive member 34 is grounded, there is little influence on the output of the wireless circuit 25 due to stray capacitance or mutual inductance generated between the conductive member of the wall surface 10 and the conductive member 34.

  Therefore, changes in the output (radio frequency, output level, etc.) of the radio circuit 25 before and after the remote controller 2 is attached to the wall surface 10 having the conductive member can be greatly suppressed.

  Further, since the radio circuit 25 is capacitively coupled to the grounded conductive member 34, it is possible to suppress the influence of external noise radiating to the radio circuit 25.

  In particular, by disposing the conductive member 34 in the vicinity of the wireless circuit 25, the strength against external noise can be increased by increasing the degree of capacitive coupling.

  Moreover, since the conductive member 34 is provided only on the back side of the substrate, the influence on the radio wave output from the wireless circuit 25 to the cleaning toilet seat device body 4 can be minimized.

  This is the same when the conductive paste is applied to the back side of the substrate 33 or when the back side of the multilayer substrate is a ground layer.

  Furthermore, a second conductive member 40 is further attached to the inner surface of the back cover 32 of the remote control device 2 (the surface facing the substrate 33), as shown in FIG.

  As described above, in the remote control device 2, the conductive member 34 is attached. However, since a radio signal must be transmitted to the cleaning toilet seat main body 4, the bottom surface (substrate 33 side) of the wireless circuit 25 is covered with the conductive member 34. I can't.

  Therefore, stray capacitance and mutual inductance between the radio circuit 25 and the conductive member of the wall surface 10 cannot be completely blocked, and when the remote control device 2 is attached to the wall surface 10, the conductive member of the wall surface 10. The influence by remains a little.

  In addition, as shown in FIG. 9, when most of the conductive member 34 is provided on the upper surface side (wall surface 10 side) of the wireless circuit 25, floating generated between the wireless circuit 25 and the conductive member of the wall surface 10. The influence due to the capacitance (C ′) and mutual inductance increases.

  Therefore, in the remote control device 2 of the present embodiment, as shown in FIG. 5, in addition to the conductive member 34, a second conductive member is provided closer to the wall surface 10 than the conductive member 34, whereby the radio circuit 25. The generation of stray capacitance and mutual inductance between the wall and the conductive member of the wall surface 10 is suppressed.

  The second conductive member 40 is formed of a metal plate such as aluminum, iron, or silicon steel. As shown in FIG. 10, the second conductive member 40 is equal to or larger than the arrangement area of the radio circuit 25 (particularly, the transmitting antenna). It has an area and is attached to substantially the entire inner surface of the back cover 32 so as to cover the radio circuit 25 and the substrate 33 on which the radio circuit 25 is mounted. Although it is desirable to ground the second conductive member 40 to the ground of the remote control circuit, it is simpler not to ground to the ground because of the structure, and it may be simply attached to the back cover 32.

  In addition, the second conductive member 40 may be electroless plated on the inner surface of the back cover 32 instead of an aluminum plate or the like. A conductive paint may be applied to the back cover 32 or the back cover 32 may be coated. It may be a conductive plastic or metal housing itself.

  Thus, in addition to the conductive member 34, the second conductive member 40 is provided on the back cover 32 between the conductive member 34 and the wall surface 10, thereby floating the conductive member on the wall surface 10 and the radio circuit 25. Generation of capacitance and mutual inductance can be reduced, and in addition to the effect of the conductive member 34, the level and frequency of the radio wave output from the transmitting antenna can be stabilized.

  Therefore, it is possible to provide a remote control device that can cope with even a standard that defines the output level of radio waves.

  In the embodiment of the present invention, the remote control device used in the cleaning toilet seat system has been specifically described. However, the present invention is not limited to this, and the present invention can also be applied to remote control devices of other electronic devices.

  In the embodiment of the present invention, the radio circuit 25 is disposed on the back surface of the substrate 33, but may be disposed on the surface of the substrate 33. In this case, as the conductive member 34, a ground surface having an area equal to or larger than the arrangement area of the wireless circuit 25 may be formed on the back surface of the wireless circuit 25, that is, the back surface of the substrate 33.

  In the embodiment of the present invention, the output of the wireless circuit is stabilized by two of the conductive member 34 and the second conductive member 40. However, the substrate 33 and the back cover 32 are close to each other. In this case, the second conductive member 40 may be attached to the back cover 32 so as to also serve as the conductive member 34. For example, the second conductive member 40 is attached to the back cover 32 so as to be adjacent to the radio circuit 25 disposed on the back surface of the substrate 33, the ground connection terminal is provided on the second conductive member 40, and the back surface of the front cover 31 is provided. When the cover 32 is attached, the ground connection terminal may be connected to the ground on the substrate.

  In the embodiment of the present invention, the toilet device system has been described. However, the present invention is not limited to this, and any electronic device that can be remotely controlled by a remote control device may be used.

  Hereinafter, the case where the present invention is applied to a bathroom equipment system will be briefly described.

  As shown in FIG. 11, the bathroom equipment system includes a bathroom dryer 100 having a dryer body 101 and a ventilation duct 102 and a remote control device 120 for controlling the dryer body 101.

  Then, by controlling the dryer main body 101 from the remote control device 120, the drying air is discharged from the dryer main body 101, and the clothes 111 hung on the clothes bar 110 are dried.

  Here, the wall surface 130 of the bathroom has a conductive member such as a vinyl chloride steel plate, like the toilet described above.

  Accordingly, as shown in FIG. 11, by attaching the remote control device 120 to the wall surface 130 of the bathroom, stray capacitance and mutual inductance are generated between the remote control device 120 and the conductive member of the wall surface 130, and the strength and frequency of the radio signal are generated. Has a major impact on

  Even in such a case, the influence of the remote control device 120 of the bathroom equipment system can be reduced by attaching the conductive member 34 and the second conductive member 40 in the same manner as the remote control device 2 of the toilet equipment system described above. Can be suppressed.
