Description

  The present invention relates to a sanitary washing apparatus system, and more particularly to a sanitary washing apparatus system that remotely controls a sanitary washing apparatus using a remote control device that uses a radio signal.

  In recent years, sanitary cleaning devices having a local cleaning function, a toilet cleaning function, a drying function, and a deodorizing function have been attached to toilet toilets. And those functions operate | move when a user operates the operation switch concentrated on the operation panel of such a sanitary washing apparatus.

  Conventionally, many of these operation panels are arranged on a sanitary washing apparatus, but recently, an operation panel provided with a remote control device has become the mainstream. Then, when the user operates an operation switch disposed on the remote control device, a control signal from the remote control device is sent to the sanitary washing device by infrared rays, and the sanitary washing device that has received the signal responds to the control signal. Control.

  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 infrared rays, communication may not be possible due to the orientation of the remote control device and the light receiving unit or the presence of obstacles. Therefore, a plurality of infrared output LEDs are arranged in a plurality of directions. There is a problem in that power consumption increases because communication is performed using infrared reflections on the side walls of the toilet booth and the ceiling, and a current of about 1 A at maximum flows.

  In order to solve the problems of communication using infrared rays as described above, there has been proposed one using communication using radio waves (for example, Patent Documents 1 and 2).

Patent 0377425 JP2007-315147A

  Such communication using radio waves described in the prior art documents 1 and 2 can reduce power consumption compared with infrared communication in a remote control device, while receiving radio waves in a sanitary washing device. The power consumption of the substrate is extremely large compared to the power consumption of the light receiving substrate that performs infrared communication.

On the other hand, in recent years, energy saving of standby power consumption of sanitary washing apparatuses has been demanded.
In general, consumption factors of the sanitary washing device during standby include consumption due to the light emission operation of the display LED, consumption due to the human body detection operation of the human body detection sensor, etc., but the ratio of the power consumption of the receiving board for radio wave communication Is relatively large.

  As a solution to this problem, use the seating detection means of the sanitary washing device, stop the operation of the receiving board when the user's seating is not detected, and operate the receiving board when the seating of the user is detected. However, the remote control device is not always a switch that is operated while the user is seated. For example, the remote control device has a switch for controlling the cleaning nozzle so that it can be easily cleaned when the user cleans the cleaning nozzle of the sanitary cleaning device, and is not seated for the purpose of cleaning the cleaning nozzle. This switch is sometimes used, and when this solution is applied, a control signal for cleaning the cleaning nozzle cannot be received.

  As another solution, the seating detection means of the sanitary washing device is used. When the user's seating is not detected, the operation of the receiving board is intermittently operated. When the seating of the user is detected, the receiving board is used. Although the remote control device cannot detect the user's seating information, the user is seated on the sanitary washing toilet seat with at least a large number of signals that can be received even in intermittent operation. Regardless of whether or not it is necessary to transmit, as a result, the power consumption of the remote control device increases and the advantage of performing radio wave communication is impaired.

  The present invention is for solving the above-mentioned problems, and the sanitary washing device can suppress power consumption during reception standby by intermittently operating the reception operation when the user is not detected. In addition, the remote control device can suppress the power consumption of the remote control device by transmitting a signal corresponding to the operation of the sanitary washing device without adding an electronic device for user detection. An object of the sanitary washing device is to provide a sanitary washing device system that can reliably receive a control signal transmitted from a remote control device.

  The invention according to claim 1 is a remote control device having a radio signal transmitting means for repeatedly transmitting a radio signal multiple times, a radio signal receiving means for receiving a radio signal transmitted from the remote control device, and the radio signal receiving means A sanitary washing device having a local cleaning means for injecting cleaning water toward the user's local area based on the radio signal received by the apparatus, a toilet seat, and a seating detecting means for detecting the seating of a human body on the toilet seat; In the sanitary washing device system, the remote control device is a seating function operation switch for transmitting a radio wave signal capable of changing the operating state of the sanitary washing device only while the seating detection means of the sanitary washing device is detecting seating. And a non-seating function operation for transmitting a radio signal that can change the operating state of the sanitary washing device regardless of the detection state by the seating detection means of the sanitary washing device The radio signal receiving means has a longer stop time when the human body detecting means for detecting the user does not detect the user than when the user is detected. The number of repeated transmissions of radio signals transmitted by operating the non-sitting function operation switch is set to be greater than the number of repeated transmissions of radio signals transmitted by operating the seating function operation switch. It is characterized by that.

According to the present invention, the radio signal receiving means of the sanitary washing device has a longer stop time when the human body detecting means for detecting the user does not detect the user than when the user is detected. By operating intermittently, the standby power consumption can be suppressed.
In addition, the remote control device does not add an electronic device for user detection, and based on the type of radio signal transmitted, the number of repeated transmissions of radio signals transmitted by operating the non-seating function operation switch is Even if the radio signal receiving means of the sanitary washing device is intermittently driven so that the stop time becomes longer because it is set more than the number of times of repeated transmission of the radio signal transmitted by the operation of the seating function operation switch The radio signal transmitted by operating the non-seating function operation switch can be reliably received and operated, while the number of repeated transmissions when operating the seating function operation switch that does not need to be received and operated in that state is Since it is not increased, the power consumption of the remote control device can be suppressed.

  Further, in the sanitary washing device system, the remote control device is an automatic transmission unit that transmits a radio wave signal that can change an operation state of the sanitary washing device regardless of a user's operation. The number of repeated transmissions of the radio signal transmitted by the automatic transmission means is set to be greater than the number of repeated transmissions of the radio signal transmitted by operating the seating function operation switch.

  According to the present invention, the remote control device does not add an electronic device for user detection, and based on the type of the radio signal transmitted, the number of times the radio signal transmitted repeatedly by the automatic transmission means is Even if the radio signal receiving means of the sanitary washing device is intermittently driven so that the stop time becomes longer because it is set more than the number of times of repeated transmission of the radio signal transmitted by the operation of the seating function operation switch The radio signal transmitted by the automatic transmission means can be reliably received and operated. On the other hand, the number of repeated transmissions when operating the seating function operation switch that does not need to receive and operate in that state is not increased. Therefore, the power consumption of the remote control device can be suppressed.

  According to a third aspect of the present invention, in the sanitary washing apparatus system, the wireless signal receiving unit uses the seating detection unit as the human body detection unit, and the seating detection unit detects the seating. If not, the operation is intermittent so that the stop time is longer than when seating is detected.

  According to the present invention, the radio signal receiving means is intermittently driven with a long stop time even when a user not seated on the toilet seat is detected as well as when the user is not detected. Standby power consumption can be further reduced.

  In the sanitary washing device system of the present invention, the sanitary washing device can suppress power consumption during reception standby by intermittently operating the reception operation when the user is not detected. In addition, the remote control device can suppress the power consumption of the remote control device by transmitting a signal corresponding to the operation of the sanitary washing device without adding an electronic device for user detection. Can reliably operate based on a control signal transmitted from the remote control device.

  Embodiments of the present invention will be described below with reference to the drawings. In addition, in each drawing, the same code | symbol is attached | subjected to the same component and detailed description is abbreviate | omitted suitably.

  FIG. 1 is a diagram showing a sanitary washing apparatus system comprising a sanitary washing apparatus according to an embodiment of the present invention installed in a toilet booth and a remote control device for controlling the sanitary washing apparatus, FIG. 2 is a block diagram of the configuration of the sanitary washing apparatus, and FIG. FIG. 4 is a front view 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, and FIG. 5 is a configuration of the remote control device according to the embodiment of the present invention. It is a block diagram.

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

  The sanitary washing device 1 is installed on the toilet bowl 3 and includes a sanitary washing device main body 4 having a control unit for controlling various functions, and a toilet seat 5 rotatably connected to the sanitary washing device main body 4. And a toilet lid 6 rotatably connected to the sanitary washing device body 4.

  The sanitary washing device main body 4 includes a sensor that functions as a human body detecting unit that detects a user in the toilet booth.

  This sensor includes an entrance sensor 71 that functions as an entrance detection unit that detects a user entering the toilet booth, an access sensor 72 that functions as an approach detection unit that detects an approach of the user to the sanitary washing device 1, It comprises three sensors called a seating sensor 7 that functions as a seating detection means for detecting a person's seating on the toilet seat 5.

  Here, the entrance sensor 71 uses a pyroelectric infrared sensor that detects infrared rays emitted from a human body or the like, and the proximity sensor 72 emits light of a predetermined wavelength toward the approaching user, and the light is transmitted to the user. It is constituted by an infrared sensor that receives reflected light and detects whether or not the user is approaching.

  The seating sensor 7 irradiates the user sitting on the toilet seat 5 with light having a predetermined wavelength, receives the reflected light reflected by the user, and determines whether the user is seated. It is comprised by the infrared sensor which detects this.

  And when this sanitary washing apparatus 1 detects the approach of the user to the toilet bowl 3 by the proximity sensor 72, the toilet lid 6 is automatically opened and when the user is not detected, the toilet lid 6 is automatically opened. A toilet lid automatic opening / closing function is provided by the toilet lid automatic opening / closing unit 61 which is automatically closed.

  The sanitary washing apparatus 1 has a local washing function by a local washing unit 81 as a local washing means for automatically washing a user's local area. When washing the local area, the cleaning nozzle 8 shown in FIG. Local cleaning is performed by spraying cleaning water toward the user's local area.

  In addition, the sanitary washing device 1 has various functions such as a toilet seat heating function by the toilet seat heating unit 51 that controls the temperature of the surface of the toilet seat 5 to a temperature at which the user feels comfortable, and a power saving function.

  In particular, the sanitary washing device 1 includes a radio receiving unit 9 that functions as radio signal receiving means for receiving a control signal from the remote control device 2 inside the sanitary washing device main body 4.

  Then, the sanitary washing device 1 activates various functions corresponding to the control signal received from the remote control device 2.

  This will be described with reference to FIG. The control signal received from the remote control device 2 is converted into an electric signal by a wireless reception circuit 91 including an antenna. The CPU 92 of the wireless receiving unit 9 having the ROM 921 and the RAM 922 decodes what kind of control command the electric signal is from the remote control device 2 and sends a control signal to the CPU 11 of the sanitary washing device having the ROM 111 and the RAM 112 for sanitary washing. The CPU 11 of the apparatus activates various functions corresponding to the control signal.

  The CPU 11 of the sanitary washing device receives a human body detection signal from the entrance sensor 71 and activates the toilet lid automatic opening / closing function of the sanitary washing device 1 or receives a signal from the seating sensor 7 to perform a local washing function. Perform safe operation.

  As shown in FIG. 3, the remote control device 2 is provided on a thin and substantially rectangular box-shaped housing 211 and on the upper surface and the front surface of the housing 211, and an operation that a user operates to remotely control the functions of the sanitary washing device 1. A plurality of operation switches that function as means and a liquid crystal display unit 212 that is provided at substantially the center of the casing 211 and displays the setting state, time, and the like of the remote control device 2, and are provided on both sides of the liquid crystal display unit 212. And a plurality of switches for setting various functions of the apparatus 1.

  As shown in FIG. 5, the remote controller has a storage unit 24 for storing various setting contents, a wireless transmission circuit 25 including an antenna that transmits a control signal as a radio wave signal to the sanitary washing device body 4, and controls the wireless transmission circuit 25. The CPU 26 for controlling the entire remote control device 2 is composed of a ROM 271 and a CPU 27 having a RAM 272. The wireless transmission circuit 25, the CPU 26 for controlling the wireless transmission circuit 25, the ROM 261 included in the CPU 26, and the RAM 262 constitute a wireless transmission unit 28 as wireless signal transmission means.

  The CPU 27 of the remote control device detects which switch among the various switches shown in FIGS. 3 and 4 is operated, and converts the control signal according to the operated switch into a radio wave and transmits it to the CPU 26 of the wireless transmission unit. The CPU 26 of the wireless transmission unit converts the predetermined control contents and the number of transmission signals into radio waves by the wireless transmission circuit 25 and transmits them to the sanitary washing device body 4.

  Incidentally, as described above, the sanitary washing device 1 has a local washing function, a toilet seat heating function, a power saving function, and the like. These functions can be roughly divided into a function that operates only when the user is seated and a function that operates regardless of whether the user is seated or not.

  Of course, the switches provided in the remote control device 2 are similarly classified. The switch for changing the operating state of the sanitary washing apparatus 1 only when the user is using the sanitary washing apparatus 1, that is, while sitting is related to various washings such as a local washing function switch, a drying switch, a washing power control switch, and a massage switch. It is a function switch. These various cleaning function switches used during the seating are called seating function operation switches 22. When the seating function operation switch 22 is operated, a signal is transmitted from the wireless transmission unit 28 of the remote control device 2, but is received by the wireless reception unit 9 in the CPU 11 of the sanitary washing device 1 of the sanitary washing device 1. The processing for changing the operating state of the sanitary washing device 1 is not performed unless the AND condition of the signal and the seating detection by the seating sensor 7 is satisfied.

  Regardless of whether the user is seated on the sanitary washing apparatus 1 or not, the switches for changing the operating state of the sanitary washing apparatus 1 are a time setting switch and a power saving time setting switch of the sanitary washing apparatus 1 There are function switches for various settings such as an automatic opening / closing setting switch for the toilet lid 6. These various setting function switches are called non-seating function operation switches 23. When the non-sitting function operation switch 23 is operated, a signal is transmitted from the wireless transmission unit 28 of the remote control device 2, and the signal received by the wireless reception unit 9 is transmitted to the CPU 11 of the sanitary washing device 1 of the sanitary washing device 1. The process for changing the operating state of the sanitary washing device 1 is performed based on the above. That is, the signal from the seating sensor 7 is not used for determining whether to change the operating state of the sanitary washing device 1.

  Next, transmission control in the wireless transmission unit 28 of the remote control device 2 will be described. FIG. 6 is a flowchart regarding transmission control of the wireless transmission unit 28 of the remote control device 2. As shown in this flowchart, first, the CPU 27 of the remote control device determines whether a switch operation has been performed (S61). When it is determined that the switch operation has been performed (S61Y), it is determined whether the operated switch is the seating function operation switch 22 or the non-sitting operation switch 23 (S62). If it is determined that the seating function operation switch 22 has been operated (S62Y), the information is sent to the wireless transmission unit 28, and the CPU 26 of the wireless transmission unit generates a transmission signal (frame signal) based on the operated switch. Then, a radio signal is transmitted from the wireless transmission circuit 25 with the first number of repeated transmissions (S63). On the other hand, if it is determined that the non-seating function operation switch is operated instead of the seating function operation switch 22 in S62 (S62N), the CPU 26 of the wireless transmission unit transmits a transmission signal (frame signal) based on the operated switch. And the radio signal is transmitted from the wireless transmission circuit 26 at the second repeated transmission count (S64). Note that the second number of repeated transmissions is set larger than the first number of repeated transmissions. The first repeated transmission may be performed once.

  The frame signal is composed of 48 bits of “communication standard information bits”, 112 bits of “control information bits (including ID bits and command signal bits)”, and 16 bits of “checksum bits”. One transmission signal. The sanitary washing device 1 can operate by receiving any one frame of the signal repeatedly transmitted from the remote control device 2 a plurality of times. In order to ensure that the sanitary washing apparatus 1 can be operated even if an error occurs in the decoding process in the above, and to match the reception possible time when the reception operation described later is intermittently operated. In addition, the transmission is repeated several times.

  Further, in the flowchart of FIG. 6, when it is determined in S61 that the switch operation is not performed (S61N), the CPU 27 of the remote control device determines whether or not the operation time of the automatic transmission means is based on the signal from the time unit 30. Judgment is made (S65). When it is determined that the operation time of the automatic transmission means is reached (S65Y), the CPU 26 of the wireless transmission unit transmits the radio wave signal from the wireless transmission circuit 26 to the current setting content (remote control setting state signal) of the remote control device 2 at the second repeated transmission count. (S64)

  The operation time of the automatic transmission means is set as a predetermined time. For example, it is set as a specific time such as midnight. This automatic transmission is a transmission for matching the information recognized inside the sanitary washing device 1 with the information set by the remote control device 2 and displayed on the liquid crystal display unit 212. When this automatic transmission signal is received, the information stored therein is forcibly changed based on the received signal.

Next, the reception operation in the sanitary washing device 1 when radio waves are transmitted from the remote control device 2 based on the flowchart of FIG. 6 will be described.
First, a conventional sanitary washing device system S not based on FIG. 6 will be described with reference to FIG. 7 which is a timing chart of its transmission operation and reception operation.

  In the sanitary washing device 1, the wireless receiving unit 9 is always activated when the seating sensor 7 detects the seating of the user, regardless of whether the seating of the user is not detected. Even if the user operates any of the sitting function operation switch 22 and the non-seating function operation switch 23 of the remote control device 2, the control signal transmitted from the wireless transmission unit 28 of the remote control device 2 has the same number of repeated transmissions. It is. In this embodiment, it is 3 times (3 frames).

  When the sanitary washing device system S is in such an operation, since the wireless reception unit 9 of the sanitary washing device 1 is always activated, the signal transmitted from the wireless transmission unit 28 of the remote control device 2 can be reliably received. Even when the user is not using the sanitary washing device 1, power consumption by the standby operation of the wireless reception unit 9 is continued, and power consumption is wasted.

  Therefore, the sanitary washing device system S according to the present embodiment allows the sanitary washing device 1 to intermittently drive the wireless receiving unit 9 when not seated, and to operate the remote control device 2 based on the flow of FIG. The device 1 can reliably receive a radio signal from the remote control device 2 and can reduce power consumption.

  Hereinafter, the reduction in consumption of the sanitary washing device system S will be described with reference to the drawings. FIG. 8 shows the number of control signals transmitted from the remote control device 2 when the user operates the seating function operation switch 22 while the user is sitting on the sanitary washing device 1, and the reception timing at the sanitary washing device 1. And it is a figure which shows the number of the control signals transmitted from the remote control device 2 when the non-seating function operation switch 23 is operated, and the reception timing in the sanitary washing device 1.

  While the user is seated on the sanitary washing device 1 (the seating sensor 7 is detecting the user), the radio wave receiving device 9 of the sanitary washing device 1 is always activated (the first receiving operation is performed). When the seating function operation switch 22 of the remote control device 2 is operated by the user, the radio transmission unit 28 of the remote control device 2 transmits a radio signal that is repeated three times, which is the first number of repetitions (FIG. 6). (See S63). Since the wireless reception unit 9 is always activated, the signal from the wireless transmission unit 28 can be received without being missed. In the present embodiment, the first number of repetitions is set to 3 times just in case of concerns about reception processing errors even during constant reception, but 1 is set in pursuit of lower consumption during transmission. It may be times, and is not limited to three times.

  Further, while the user is seated on the sanitary washing device 1, the operation of the non-sitting function operation switch 23 of the remote control device 2 by the user is extremely less than the rate at which the seating function operation switch 22 is operated. A radio signal repeated 15 times, which is the second number of repetitions, is transmitted from the wireless transmission unit 28 of the remote control device 2 (see S64 in FIG. 6). The number of repetitions is not limited to 15, but is set by the intermittent activation operation cycle of the radio wave receiver 9 of the non-seated sanitary washing device 1. The concept will be described in detail later.

  FIG. 9 shows the remote control device 2 when the seating function operation switch 22 is operated by the user when the user is not seated on the sanitary washing device 1 (when the seating sensor 7 is not detecting the user). The number of control signals transmitted and the reception timing at the sanitary washing device 1, and the number of control signals transmitted from the remote control device 2 and the reception timing at the sanitary washing device 1 when the non-sitting function operation switch 23 is operated. FIG.

  When the user is not seated on the sanitary washing device 1, the radio wave receiving device 9 of the sanitary washing device 1 performs an intermittent activation operation (performs a second reception operation). Since the user is not seated on the sanitary washing device 1, even if the user operates the seating function operation switch 22 of the remote control device 2, the sanitary washing device 1 cannot change the operating state based on the received signal. Absent. For example, even if the local cleaning start switch that is the seating function operation switch 22 is operated, the sanitary cleaning device 1 does not start the local cleaning operation. Therefore, when not seated on the sanitary washing device 1, the wireless reception unit 9 does not need to receive a signal transmitted from the wireless transmission unit 28 when the seating function operation switch 22 is pressed. Therefore, the stop time in the intermittent activation operation of the radio wave receiving device 9 of the sanitary washing device 1 is longer than the period in which the seating function operation switch 22 is operated and repeatedly transmitted three times. Even if the timings are received at the same timing, as described above, the sanitary washing device 1 does not detect the seating, so that the operation of the sanitary washing device 1 is not changed.

  On the other hand, it is necessary to receive the 15 repetitive radio signals transmitted by operating the non-sitting function operation switch 23 of the remote controller 2 without being missed. Therefore, in the present embodiment, the activation time of the intermittent activation operation of the sanitary washing device 1, that is, the time during which the radio wave receiver 9 is operating in order to capture radio waves is 10 msec, and the radio wave receiver 9 has stopped operating. Intermittent drive with a time of 90 msec. The control signal transmitted from the remote control device 2 is set to 5 msec in this specific example from the time when the first control signal is transmitted until the next control signal is transmitted. If the time width of one control signal is not set to be smaller than 5 msec, the operation time of the radio wave receiver 9 is exceeded, so that it cannot be received. In this embodiment, the time width of the control signal is about 2 msec. In addition, in order for the radio wave receiving device 9 of the sanitary washing device 1 to reliably receive the control signal transmitted from the remote control device 2, it is necessary to set at least longer than 100 msec, which is the period of the intermittent activation operation performed by the radio wave receiving device 9. Therefore, in this specific example, 15 control signals are used. By setting the time of this specific example, the sanitary washing device 1 can reduce the power consumption during standby to about 1/10.

  When the user operates the non-sitting function operation switch 23 of the remote control device 2, there is a concern that the power consumption of the remote control device 2 increases by increasing the number of repetitions of the transmitted control signal. In actual use, the non-sitting function operation switch 23 is operated in an extremely small amount compared to the ratio in which the seating function operation switch 22 is operated, and the influence on the battery life of the remote control device 2 is very small.

  In FIG. 8, when the user is seated on the sanitary washing device 1, the wireless reception unit 9 of the sanitary washing device 1 is always activated, but it may be intermittently activated even while sitting. By doing so, the power consumption of the sanitary washing device 1 can be further reduced. However, in that case, at least the wireless reception unit 9 of the sanitary washing device 1 is always activated so that the number of control signals transmitted when the seating function operation switch 22 of the remote control device 2 is operated can be received even in the intermittent activation operation. It is necessary to set to transmit a larger number of control signals than in the case where

Next, a modified example of the present invention will be described.
A function of changing the operating state of the sanitary washing device 1 is added to the recent remote control device 2 regardless of the operation of the user. This function is called an automatic status transmission function. This automatic state transmission function is controlled by automatic transmission means built in the CPU 27 of the remote control device, and the purpose of adding this function is to eliminate the mismatch between the setting state of the remote control device 2 and the setting state of the sanitary washing device 1. It is to do. Specifically, the setting functions transmitted by the automatic state transmission function include the automatic opening / closing function setting of the toilet lid, the automatic deodorizing function setting of the sanitary washing device, and the power saving function setting.

  An embodiment of the automatic status transmission function of the remote control device 2 will be described in detail with reference to FIG. Automatic status transmission is transmitted only once every 24 hours, excluding automatic status transmission 10 minutes after battery insertion. Since the remote control device 2 has a clock function, the transmission time can be measured almost accurately. When the remote control device 2 performs automatic status transmission, it cannot be specified whether the user is present or absent in the toilet booth. Therefore, the radio wave reception device 9 of the sanitary washing device 1 may be always activated or intermittently activated. It cannot be specified.

  In such a state, the sanitary washing device 1 reliably receives the automatic state transmission signal without missing it, and the transmission frequency of once every 24 hours is compared with the number of transmissions by the operation of the seating function operation switch 22. Since it is extremely low, the number of automatic state transmission signals is the same as the number of repetitions described in the non-seating function operation switch 23. Since the transmission frequency is once every 24 hours, the influence on the battery life is very slight.

  As described above, the number of repetitions of the signal to be transmitted when the seating function operation switch 22 and the non-sitting function operation switch 23 are operated, and the repetition of the signal to be transmitted at the time of transmission based on the user's operation and at the time of automatic transmission. By setting the number of times according to the intermittent operation of the radio wave receiver 9 in which the reception operation is switched using the seating sensor 7 provided in the sanitary washing device 1, the remote control device 2 is provided with an electronic device for user detection. The consumption of the sanitary washing device system S can be reduced.

  Further, by setting the number of automatic state transmission signals to be at least the same as the number of control signals transmitted when the non-seating function operation switch 22 is operated, an electronic device for user detection is not added to the remote control device 2. Further, the consumption of the sanitary washing apparatus system S can be reduced.

  The embodiment of the present invention has been described above. However, the present invention is not limited to these descriptions. As long as the features of the present invention are provided, those skilled in the art appropriately modified the design of the above-described embodiments are also included in the scope of the present invention. For example, the time interval between the control signals transmitted from the remote control device 2 and the control signals, the number of control signals, the time width of the control signals, and the period in which the radio wave receiving device 9 of the sanitary washing device 1 performs an intermittent operation is operating. The time, the stopped time, and the like are not limited to those illustrated, and can be changed as appropriate. In the embodiment, the operation of the wireless reception unit 9 of the sanitary washing device 1 is switched between the first reception operation (always activated) and the second reception operation (intermittent drive) based on the detection result of the seating sensor 7. However, the receiving operation may be switched based on the result of human body detection / non-detection based on the entrance sensor 71 or the proximity sensor 72. Moreover, each element with which each embodiment mentioned above is provided can be combined as long as technically possible, and the combination of these is also included in the scope of the present invention as long as it includes the features of the present invention.
