Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating toilet seat device, and more particularly to a heating toilet seat device capable of recognizing a temperature of a toilet seat. 2. Description of the Related Art In a heating toilet seat device, it is convenient for a user to recognize the temperature of a toilet seat before sitting on the toilet seat.
It is extremely important from the viewpoint of safety. Therefore, a conventional heating toilet seat device, for example, as disclosed in JP-A-11-52892, a lamp is provided as a temperature indicator,
The brightness of the lamp was changed according to the temperature of the toilet seat. [0003] However, such a temperature display is not useful, for example, when the user is a low-vision person, or when he or she is going to sit down with his eyes down. [0004] Therefore, an object of the present invention is to provide a heating toilet seat device provided with such a temperature display body having no trouble. [0005] A first means taken to solve the above-mentioned problem is as follows: "A temperature report which generates a different sound depending on the surface temperature of the toilet seat heated by the heating means. Is provided. " In the present invention, since a temperature reporting section for generating different sounds according to the surface temperature of the toilet seat is provided, the user can surely recognize the toilet seat temperature. Hereinafter, embodiments of a heating toilet seat device according to the present invention will be specifically described. 1 to 3, a case 12 for accommodating a main part (not shown) of the human body local cleaning device is placed on a rear upper edge portion of the toilet bowl 10 installed in the toilet space. Here, the main part of the human body local cleaning device refers to a portion other than the nozzle (not shown), and includes a control device, a hot water tank, and a mechanism for driving the nozzle as main components.
A toilet lid 14 and a toilet seat 16 are pivotally supported on the case 12 by a common pin means (not shown) in a known manner. The toilet seat 16 is formed of a thin stainless steel plate having a thickness of 0.5 mm. The inner edge and the outer edge of the back portion of the toilet seat 16 are fitted and fixed to the inner edge projection and the outer edge projection of the back plate 18 made of PP material, respectively. In addition, a bracket 20 provided substantially at the center of the back surface (rear surface) of the toilet seat 16 has a support 2 extending from the back plate 18 to the rear surface.
2 supported. Thus, the toilet seat 16 having such a support structure can be used even when a user (not shown) is seated.
Robustness can be maintained without deformation. On the back surface of the toilet seat 16 made of a stainless steel sheet,
A heater 30 is provided. Specifically, the heater 30
Is coated with an insulating material (not shown), and the insulating material is bonded to the back surface of the toilet seat 16. As is well known, the back surface of the toilet seat 16 is roughly O-shaped (or Δ-shaped), and the heater 30 extends and extends on an O-shaped (or Δ-shaped) plane while repeating meandering. Is established. The heater 30 is connected to a commercial power supply 50 via a triac 34, a power switch 36, and a fuse 38 so as to form a closed circuit. The power switch 36 is normally closed, but the triac 34
Is open as long as the user does not indicate that it is close to the toilet 10, as will be described in detail below. That is, energization of the heater 30 is not performed at all times, but is performed only when the user indicates a sign of approaching the toilet 10. As a result, wasteful power consumption caused by constant power supply to the heater 30 is prevented. The triac 34 is connected to a triac drive circuit 48 under the control of the microcomputer 40.
The microcomputer 40 operates the triac drive circuit 48 to open / close or turn on / off the triac 34. The microcomputer 40 includes a human body detection sensor 42,
The toilet seat temperature sensor 44 and the seating detection sensor 46 are connected. As shown in FIG. 1, the human body detection sensor 42 is exposed at an upper left portion of the case 12 and points to a door (not shown) located in front of the paper surface. When the user opens the door and steps into the toilet space, the human body detection sensor 42
That effect (specifically, an ON signal) is sent to the microcomputer 40. Note that the human body detection sensor 42 employs a current-collecting infrared sensor that does not generate an ON signal unless the target moves. In addition, instead of the human body detection sensor 42, a switch that turns on and off the detection of the sign of the user stepping into the toilet space or the sign of approaching the toilet 10 is used, for example, in conjunction with a door that controls the open / close space of the toilet space. You may. When the microcomputer 40 receives the ON signal from the human body detection sensor 42, the microcomputer 40 operates the triac drive circuit 48 to close (turn on) the triac 34, and the heater 30
A voltage is applied from the commercial power supply 50 (power is supplied),
Rapid heating or heating of the toilet seat 16 is performed. That is, the microcomputer 40 energizes the heater 30 so as to eliminate the difference between the set temperature (the temperature is set in three stages of high, medium and low) and the current temperature of the toilet seat 16 indicated by the signal from the toilet seat temperature sensor 44. I have to. Specifically, according to the difference between the set temperature and the current temperature of the toilet seat 16 indicated by a signal from the toilet seat temperature sensor 44, the amount of electricity (electric power) to be supplied to the heater 30
Is made for a corresponding time in correlation with the ambient temperature.
When the temperature of the heater 30 reaches the set temperature, in order to maintain the set temperature, the microcomputer 40 causes the triac drive circuit 48 to repeatedly open and close the triac 34 at a predetermined cycle, and to perform the duty control on the energization of the heater 30. Perform in. Thus, the user can sit comfortably on the toilet seat 16 because the temperature of the toilet seat 16 reaches or immediately before the temperature reaches the set temperature. During the seating, the ON signal is always emitted from the seating detection sensor 46. When the user leaves the toilet seat 16, the ON signal changes to an OFF signal. After the signal changes, after a lapse of a predetermined time, the microcomputer 40 operates the triac drive circuit 48 to open the triac 34, and the commercial power supply 5
Power supply to the heater 30 from 0 is stopped. A speaker 80 exposed to the outside is provided inside the left sleeve of the case 12, and from this speaker 80, when a person enters the toilet space, the toilet seat 1 is opened.
A sound corresponding to the temperature level of No. 6 is emitted, and the temperature of the toilet seat 16 is audibly recognized by the user. That is, in accordance with the level of the signal from the toilet seat temperature sensor 44, the microcomputer 40 sends a pre-stored sound signal to the speaker 80 to make the user hear this sound. Accordingly, when the user enters the toilet space with a sleeping eye or when the user is amblyopia, the toilet seat 1 is surely set.
The temperature of 6 can be notified to the user in advance. Thereby, the user can sit on the toilet seat 16 as it is,
The user will sit on the toilet seat 16 by raising or lowering the temperature. In this way, unexpected discomfort or uncomfortable feeling is eliminated when the user sits down without being informed of the temperature of the toilet seat 16, which is a great effect in practical use. The sound may be a melody that becomes treble as the temperature rises, or may be an artificial voice that utters a temperature level. Further, the installation position of the speaker 80 is not limited to the above-described location, but may be another position of the heating toilet seat device 10 or a wall or ceiling of the toilet space. According to the present invention, the heating toilet seat device is provided with the temperature notification section which changes the sound depending on the surface temperature of the toilet seat, so that the user can surely measure the toilet seat temperature before sitting. Recognizable,
Convenience and safety can be ensured, and a great effect is practically achieved.
