Description

  The present invention relates to a toilet apparatus which is installed on a toilet bowl and has a toilet seat lid and a heated toilet seat which can be automatically opened and closed.

  Conventionally, in this type of toilet apparatus, there has been a device that automatically opens and closes the toilet seat and the toilet seat lid by the human body detection means and informs the user by chime immediately before each of them operates (for example, see Patent Document 1). In such a conventional toilet apparatus, as shown in FIG. 2, the toilet seat controller 6 controls the energization of the heater 2 by controlling the temperature of the toilet seat 1 installed on the toilet 1a based on the temperature detected by the temperature detecting element 3. The toilet seat lid 4 is closed by the toilet seat lid control unit 10 in order to maintain a suitable sitting temperature suitable for sitting and to suppress heat dissipation when not in use. Further, when the toilet seat cover control unit 10 detects that a person enters the toilet room by the human body detection means 5, the toilet seat cover 4 is opened to be in a seatable state, and at the same time, the chime 8 is sounded and the user is to be operated. It was to inform them.

In recent toilet apparatuses, a technique for increasing the temperature of a toilet seat in a short time from room temperature has been developed (see, for example, Patent Document 2).
JP-A-6-090876 (FIG. 1) JP 2000-14598 (FIG. 1)

  In the above-described conventional configuration, the human body detecting means 5 detects the person entering the toilet room and immediately rings the chime 8 to open the toilet seat lid 4 so that the toilet seat 2 has a temperature suitable for sitting. Then I had a problem that I didn't understand. In the case of a toilet device, since the user needs to keep the seating surface of the toilet seat 2 as clean as possible, it is usually set higher than the temperature at which the user sits, and molds attached to the seating surface of the toilet seat 2 In some cases, a function to remove bacteria is added, but if the chime 8 is sounded and the toilet seat lid 4 is immediately opened in this function state, the temperature does not drop immediately even when the heater 2 is turned off, and the user is seated and uncomfortable. It is possible to feel it.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by this Embodiment.

  FIG. 1 is a block diagram of a toilet apparatus according to Embodiment 1 of the present invention. The toilet seat 1 is installed upside down on the toilet bowl 1a around the rear end portion as shown by an arrow, and a heater 2 for heating the seating surface by generating heat by energization is wired inside. The temperature detection element 3 is composed of a thermistor and is disposed in the toilet seat 1 to detect the temperature of the toilet seat. The toilet seat lid 4 is controlled in its open / closed state as shown by an arrow in the figure by a driving means (not shown) such as a motor, and covers the toilet seat 1 when closed.

  The toilet seat control unit 11 is composed of a microcomputer and its peripheral circuits, and takes in the detected temperature of the temperature detecting element 3 so that the temperature of the seating surface of the toilet seat 1 becomes a first temperature that is a suitable seating temperature suitable for a predetermined seating. The energization to the heater 2 is controlled in accordance with the detected temperature, that is, the energization to the heater 2 is controlled to be on when the set temperature <the detected temperature, and off otherwise. At this time, since the energization rate to the heater 2 is proportional to the heat dissipation rate of the toilet seat 1, that is, the difference between the temperature of the toilet seat 1 and the room temperature, the energization rate, that is, the power consumption is reduced by lowering the temperature of the toilet seat 1 when not in use. Can be dropped.

  The toilet seat lid control unit 12 includes a microcomputer and its peripheral circuits, and is configured integrally with or separate from the toilet seat control unit 16 to control the driving means to open and close the toilet seat lid 4 and when the toilet seat 1 is not used. Control to close the lid 4 is performed, that is, when the temperature of the toilet seat 1 is equal to or lower than a predetermined second temperature lower than the first temperature, the heat release from the toilet seat 1 is suppressed by closing the toilet seat lid 4. The human body detection means 5 includes a pyroelectric sensor that detects infrared rays emitted from the human body, and detects that a person has entered the toilet room.

  Therefore, the toilet seat controller 16 energizes the heater 2 when it receives a signal indicating the presence of a person from the human body detector 5. In general, it takes about 5 to 10 seconds from entering the room to sitting, so if the temperature of the toilet seat 1 is set to 40 ° C., which is the original first temperature, it is 30 ° C. when the toilet seat 1 is not used. When energization of the heater 2 is started and the temperature reaches 35 ° C. in about 5 seconds, the toilet seat lid control unit 17 opens the toilet seat lid 4 by driving means. And since the toilet seat 1 is not much different from the body surface temperature around 35 ° C, there is almost no discomfort or discomfort even when seated, and the toilet seat temperature is kept at 30 ° C when not in use, so comfort And economic efficiency.

  The mode activation switch 7 is operated to thermally remove mold and bacteria attached to the surface of the toilet seat 1, and sends a sterilization start signal to the toilet seat control unit 11. Therefore, the toilet seat control unit 11 takes in the operation signal of the mode activation switch 7 and controls the energization of the heater 2 so that the temperature of the toilet seat becomes equal to or higher than a predetermined third temperature set higher than the first temperature, and after a predetermined time. In addition to controlling to return to the first temperature, when the human body detecting means 5 detects a human body, the temperature of the toilet seat 1 is returned to the first temperature even during the sterilization to speed up the timing of the appropriate seating. good. On the other hand, the toilet seat cover control unit 12 controls the toilet seat cover 4 to be in a closed state based on the fact that the toilet seat control unit 11 sets the temperature of the toilet seat 1 to be equal to or higher than a predetermined third temperature set higher than the first temperature. Improve the sense of security by not being able to sit on the temperature toilet seat 1.

  The above-mentioned sterilization action will be described in further detail. When the mode start switch 7 is pressed while the toilet seat lid 4 is closed, the temperature of the toilet seat 1 is maintained at 50 ° C. for about 30 minutes. Thereby, the mold | fungi and microbe which adhered to the toilet seat 1 surface can be removed thermally. The toilet seat 1 is made of a resin, and 50 ° C. is not a temperature at which a user is burned immediately after sitting, but is a temperature sufficient to surprise the user.

  Therefore, in the present embodiment, the monitor display unit 9 of the toilet seat 1 is provided, and is controlled based on the toilet seat control unit 11 so that it becomes green at an appropriate seating temperature, that is, 35 to 45 ° C., and red beyond that. That is, the toilet seat control unit 11 controls the temperature of the toilet seat 1 to 50 ° C., and immediately energizes the heater 2 based on the signal detected by the human body detecting means 5 when the user enters the room. Even if it is turned off, because the heat capacity of the toilet seat 1 is present, it takes about 2 to 5 minutes for the temperature to fall below 45 ° C. (inversely proportional to the room temperature), so it is impossible to wait and try to open the toilet seat lid 4 by hand. A user is considered.

  Therefore, in the present embodiment, when the user tries to open the toilet seat lid 4 when the temperature of the toilet seat 1 is 45 ° C. or higher (including the case where the toilet seat lid 4 is opened), the monitor display unit 9 blinks red to alert the user. In addition, the user is informed that the user should not sit on the toilet seat 1 by sounding the notification means 8 such as a buzzer.

  As described above, in the present embodiment, it is possible to provide a function that is extremely useful for the user, which is called a high-temperature sterilization function, without greatly impairing safety.

  In the above embodiment, the toilet seat control unit 11 receives a sterilization start signal from the mode activation switch 7, but is further configured to accept the toilet seat 1 in a state where it is raised with respect to the toilet 1 a, You may be able to raise your sense of security by visually appealing that you can't sit on a hot toilet seat by standing 1. In addition, the toilet seat control unit 11 receives a signal to start sterilization by the mode activation switch 7, but the toilet seat control unit 11 is configured so as not to receive a signal to start sterilization unless the toilet seat cover 4 is closed. Since the user cannot sit on the toilet seat 1, the user can clearly recognize that the temperature of the toilet seat 1 is high.

  Further, in the above embodiment, when the toilet seat lid 4 is opened to use the toilet seat 1 during the above-described sterilization, the monitor display unit 9 displays the fact that the sterilization is being performed to call attention. The toilet seat control unit 11 may be configured to perform control for causing the monitor display unit 9 to perform a display different from the state in which the toilet seat lid 4 is closed.

  That is, when the toilet seat 1 is not suitable for sitting, for example, when the toilet seat lid 4 is opened and used at a high temperature during sterilization higher than the third temperature or at a temperature lower than the second temperature, the toilet seat lid is already opened on the monitor display section. The user can be prevented from being seated on the toilet seat by mistake because the user does not open the toilet seat lid.

Furthermore, in the above embodiment, the toilet seat control unit 11 notifies that the temperature is higher during the sterilization than the third temperature when the toilet seat lid 4 is opened to use the toilet seat 1 during the sterilization. However, the notification means may notify the user when the toilet seat lid 4 is opened at a temperature lower than the second temperature and the toilet seat 1 is used.

  Furthermore, as the heater 2 in the above-described embodiment, a sheathed heater that gradually rises in temperature when energized, instantaneously generates heat and radiates when energized, and is converted into heat by a heat absorption layer provided near the seating surface of the toilet seat. A lamp heater that warms the seating surface of the toilet seat may be used.

  As described above, the toilet apparatus according to the present invention prevents the user from accidentally sitting on the toilet seat when the temperature of the toilet seat is not the optimum seating temperature, allows the toilet seat to be used at an appropriate temperature, is easy to use, and has high security. Since the toilet seat function can be provided, the present invention can be applied to a toilet seat having functions of local washing, local drying, deodorization, and the like.
