Description

  The present invention relates to a toilet device mainly composed of a toilet provided with toilet cleaning means and a toilet seat device attached to the toilet.

  Conventionally, a toilet device including a toilet cleaning means and a toilet seat device is known (see, for example, Patent Document 1). In this conventional example, the toilet bowl cleaning means and the toilet seat device are incorporated in the toilet bowl as one device block. The single device block is provided with a seating / seating detection means and a control unit, Seating / separation is detected by the seating detection means, and based on the detection result, the control unit controls the local cleaning means and the toilet bowl cleaning means.

  In the above conventional example, since the toilet bowl cleaning means and the toilet seat device are incorporated in the toilet bowl as one device block, it is not possible to replace only the toilet seat device with another toilet seat device having a different shape, color or function. There is a problem that it is possible to meet the needs of various customers, and the toilet seat device is easy to get dirty, so when removing and cleaning it, there is a problem that the toilet seat device part cannot be removed and cleaned easily. It was.

  In order to solve these problems, a toilet seat device equipped with a separate seating / separation detecting means is attached to a toilet device equipped with toilet cleaning means, and the toilet seat device and the toilet bowl equipped with toilet cleaning means are wired. It is conceivable to control the toilet flushing means provided in the toilet based on the data detected by the seating / seating detection means provided in the toilet seat device. In this case, the toilet bowl provided with the toilet seat device and the toilet flushing means Therefore, it is necessary to connect the toilet bowl equipped with toilet cleaning means and the toilet seat device with wiring during construction. Also, when cleaning, the wiring for connecting is obstructive. Furthermore, because of the nature of a toilet device that uses water, there is a risk that water may enter the control unit through the wiring for the above connection. Wiring that cannot be made Waterproof structure is complicated, including a connecting portion, a problem occurs.

  Therefore, instead of connecting the toilet bowl and the toilet seat device by wiring, it has been considered to use radio waves such as infrared rays for communication between the toilet bowl and the toilet seat device. However, when wireless communication such as infrared rays is used for communication, wireless communication is not normally performed when there is a strong disturbance such as sunlight. In this case, it is necessary to perform wired communication that is not affected by the disturbance. Therefore, it is preferable that wireless or wired can be selectively used for communication between the toilet bowl side and the toilet seat apparatus side.

However, since the processing of the signal received on the receiving side is performed by the same signal processing unit regardless of whether it is wireless or wired, a wireless signal and a wired signal are mixedly input to the signal processing unit. Normal processing is not performed. Therefore, it is necessary to automatically switch the signal input to the signal processing unit between wireless communication and wired communication.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 2, the toilet device of the present invention is mainly composed of a toilet 1 having toilet cleaning means and a toilet seat device 2 that is placed on a rim of a toilet body 11 of the toilet 1 and seated by a user. Composed.

  The toilet bowl 1 includes toilet bowl cleaning means for cleaning the bowl portion with water in the toilet bowl body 11, and in this embodiment, a turn trap is mounted at the rear part of the toilet bowl body 11 as toilet bowl cleaning means, although not particularly shown. A toilet control unit case 12 is provided on the upper surface of the rear part of the toilet body 11. A toilet control unit (not shown) for driving the turn trap is housed in the toilet control unit case 12, and receiving means 4 for receiving a signal to be described later and signal processing for processing the received signal Part 5 is provided.

  The toilet seat device 2 includes a toilet seat 21 on which a human body is seated, a local cleaning means for cleaning a local part of the user (not shown), and a drying means for drying the local part of the user by blowing air after cleaning the local part. The toilet seat side function unit such as deodorizing means for deodorizing the toilet body 11 and the toilet seat side control unit 6 including a so-called microcomputer for controlling the toilet seat side function unit. An operation unit 22 for inputting a command, a transmission unit 3 for transmitting a signal to the toilet 1 side, and a seating / seating detection unit for detecting seating / seating on the toilet seat 21 are provided.

  An example of the control operation of the toilet device will be described. First, when the user is seated on the toilet seat 21 of the toilet seat device 2, the seating is detected by the seating / separation detecting means, and when the user is seated after the seating, the seating is detected. When seating / seating is detected by the seating / separation detecting means, a seating signal or a seating signal is input to the toilet seat side control unit 6, and a plurality of toilet seats are received by the toilet seat side control unit 6 based on the seating signal or the seating signal. One or more of the side function units are controlled. For example, when a seating signal is input, the deodorizing means, which is one of the toilet seat side functional units, is turned on to start deodorization. After that, when a seating signal is input, a certain time elapses after the seating signal is input. It is controlled so that the deodorizing means is turned off later. Further, when the seating signal is input, the mode of accepting the operation of the local cleaning means for cleaning the user's local area is entered. After that, the mode of accepting the operation of the local cleaning means is terminated when the seating signal is input. When a command is input from the operation unit 22 provided in the toilet seat control unit case, the local cleaning means is operated by the toilet seat side control unit 6 only during the operation accepting mode (that is, only during the sitting period). The local cleaning means is not operated when it is not in the operation accepting mode (that is, when it is not seated). This prevents the local cleaning means from operating accidentally when the user is not seated, and ejecting cleaning water such as warm water.

  Further, when the user leaves after sitting, and the seating / seating detection means detects the seating / seating, a signal having information on seating / seating is transmitted from the transmission means 3 of the toilet seat side control unit 6. The toilet 4 is received by the receiving means 4 of the toilet 1 and the toilet cleaning means operates to automatically clean the toilet. Note that even if the user inputs a toilet cleaning command from the operation unit 22 of the toilet seat device 2, a signal is similarly transmitted from the transmission unit 3 of the toilet seat side control unit 6 and received by the receiving unit 4 of the toilet 1. Then, the toilet bowl cleaning means is activated to perform toilet bowl cleaning. As described above, communication is performed between the toilet 1 side and the toilet seat device 2 side, and the communication can be selectively performed wirelessly or by wire, and will be described below.

  The toilet seat apparatus 2 is provided with a wireless transmission unit 30 for transmitting signals wirelessly and a wired transmission unit 31 for transmitting signals by wire as the transmission means 3, and the toilet 1 has the wireless transmission as the reception means 4. A wireless reception unit 40 that receives a signal transmitted from the unit 30 and a wired reception unit 41 that receives a signal transmitted from the wired transmission unit 31 are provided.

  A case of wireless communication will be described. In the present embodiment, for example, a radio signal uses a carrier made of infrared rays having a carrier frequency of 38 kHz, and when it is ON, a pulse is generated and a pulse train is generated and transmitted so as not to generate a pulse when OFF. The pulse width of the pulse train or the length / shortness of the pulse interval is made to correspond to 1-bit information, and predetermined information is put on the pulse train.

  The wireless signal is transmitted as an electric signal generated by the toilet seat side control unit 6 of the toilet seat apparatus 2 to the wireless transmission unit 30 including a light emitting element and transmitted from the wireless transmission unit 30 as a wireless signal including infrared rays. On the toilet 1 side, there is provided a radio receiving unit 40 made of a light receiving element. The radio signal received by the radio receiving unit 40 becomes an electric signal, and the signal processing unit 5 is connected via a switching unit 8 made of a relay described later. Is input.

  Although not shown, the signal processing unit 5 includes an amplifier that amplifies the electric signal from the radio reception unit 40, a filter that extracts a carrier frequency component from the electric signal from the amplifier, and a waveform shaping that shapes the output signal from the filter. Unit, an integrating unit that integrates the output signal from the waveform shaping unit, and an output unit that outputs a pulse when the output signal from the integrating unit is higher than the threshold value by comparing with the threshold value. The signal is processed by associating the pulse width of the pulse train of the output signal or the length / shortness of the pulse interval with 1-bit information.

  Next, a case where communication is performed by wire will be described. Also in the case of wired communication, the electrical signal generated by the toilet seat side control unit 6 of the toilet seat device 2 is branched in the middle and input to the wired transmission unit 31 as in the case of the wireless signal. The wired transmission unit 31 of the toilet seat device 2 and the wired reception unit 41 of the toilet 1 are connected by a connection line 7 composed of two communication lines, and a signal input to the wired transmission unit 31 is received via the connection line 7 by wired reception. Input to the unit 41.

  The wired transmission unit 31 includes a transmission side socket 32 into which one end portion 7 a of the connection line 7 is inserted, and a first transmission in which the one end portion 71 a of one communication line 71 of the connection line 7 is in contact with the transmission side socket 32. It has the 2nd transmission side contact 34 which the side contact 33 and the one end part 72a of the other communication line 72 contact | connect. Further, the first transmission side contact 33 and the second transmission side contact 34 are connected via a transmission side resistor 35, and the first transmission side contact 33 and the second transmission side contact 34 are connected to each other. A wired signal generation unit 36 that generates a signal by switching between a substantially insulated state and a conductive state according to a signal is provided so as to be in parallel with the transmission-side resistor 35.

  The wired receiving unit 41 includes a receiving side socket 42 into which the other end 7b of the connection line 7 is inserted, and a first end 71b of the one communication line 71 of the connecting line 7 in contact with the receiving side socket 42. And the second receiving side contact 44 with which the other end 72b of the other communication line 72 is in contact. A predetermined voltage is applied to the first reception side contact 43 via the reception side resistor 45, and the second reception side contact 44 is grounded.

When performing communication by wire, first, one end portion 7 a of the connection line 7 is inserted into the transmission side socket 32 of the wired transmission unit 31 and the other end portion of the connection line 7 is inserted into the reception side socket 42 of the wired reception unit 41. 7b is inserted, and the first transmission side contact 33 and the first reception side contact 43 are made conductive through one communication line 71, and the second transmission side contact 34 and the second reception side contact 44 are connected. Is made conductive through the other communication line 72. Thereby, the receiving side resistor 45, the first receiving side contact 43, the one communication line 71, the first transmitting side contact 33, the transmitting side resistor 35, the output unit 36a of the wired signal generating unit 36, the second transmitting side. A predetermined voltage is applied in series between the contact 34, the other communication line 72, and the second reception contact 44. Here, when a signal from the toilet seat side control unit 6 is input to the wired signal generation unit 36 of the wired transmission unit 31, the output unit 36 a of the wired signal generation unit 36 (part disposed in parallel with the transmission side resistor 35). ) Are both electrically insulated when the signal pulse is turned on and are substantially insulated when turned off. When the signal pulse is insulated, the divided voltage V ′ of the receiving resistor 45 is set to V ₁ and the receiving resistor 45 is set to R ₁ , assuming that the transmission-side resistor 35 is R ₂ , V ′ = V ₁ · R ₁ / (R ₁ + R ₂ ), and V ′ = 0 in the conductive state. Therefore, and it reads a signal from the change in the potential V of the first receiving-side contacts 43, specifically, type the potential of the first receiving-side contacts 43 to the comparator C _1, for example, REF 1 ₌ V _{1 · R 1/2 (R} 1 + R 2) as compared with the output produced high and low as the recovered signal, so as to enter it and to the signal processing unit 5.

  By the way, when performing communication by wire, as described above, the connection line 7 is inserted and connected to the transmission side socket 32 and the reception side socket 42. At this time, the signal from the wireless reception unit 40 is a signal. When the signal is input to the processing unit 5, the signal processing unit 5 causes interference, and therefore the input to the signal processing unit 5 needs to be switched so that only one of the wireless reception unit 40 and the wired reception unit 41 is input. At this time, if you switch manually, you may forget to switch, so it is desirable to switch automatically.

Therefore, when the connection line 7 is connected as described above, the potential V of the first reception side contact 43 changes between V ₁ · R ₁ / (R ₁ + R ₂ ) to 0, and the connection line 7 is when not connected so that the potential V of the first receiving-side contacts 43 for the V _1, in the present embodiment switches to determine this. In other words, the partial pressure of the reception-side resistor 45 is measured, discriminated, and switched. Specifically, the potential V of the first receiving-side contacts 43 and inputted to the comparator _{C 2} different from the above, for example, _{REF 2 = V 1 · (R} 1 + R 2/2) / (R 1 + R 2 ), When V> REF ₂ , the switching unit 8 made of a relay provided in front of the signal processing unit 5 switches to the wireless receiving unit 40 side, and when V <REF ₂ , the switching unit 8 performs wired operation. Switching to the receiving unit 41 side is performed.

According to the configuration as described above, it is possible to automatically switch the signal input to the signal processing unit 5 between the case of performing wireless communication and the case of performing wired communication. Therefore, it is possible to prevent interference from being made only from either of the above signal and the signal from the wired receiver 41. In this case, it is possible to switch the existing circuit or the like without changing by merely providing the comparator C ₂ and the switching unit 8, and each end of the connection line 7 is connected to the transmission side socket 32. And can be automatically switched by simply inserting it into the receiving socket 42, and there is no fear that the user forgets to switch.
