Problems solved by technology

In addition, due to the detection of seating, the deodorization function is automatically started, and the power saving mode is released, which wastes power.
[0011] As mentioned above, misjudging that the user does not exist, and misjudging the existence of the user will cause inconvenience
That is, if the existence position and situation of the user cannot be correctly judged, the function of the toilet device cannot be fully utilized.

Embodiment approach 1

[0035] figure 1 It is a perspective view explaining the toilet device in Embodiment 1 of this invention. figure 2 This is a block diagram illustrating the operation of its control processing.

[0036] The main body 1 has a washing water spout part 2 that spouts warm water toward a part of the human body. An openable and closable toilet seat 3 and a cover 4 are attached to the main body 1, and a distance measuring unit 5 for measuring the distance to obstacles is also attached. The remote control device 6 has an operation unit and a display unit corresponding to the functions of the toilet device (for example, a washing function, a drying function, a deodorizing function, and a toilet seat heating function), and sends signals to the main body 1 . The judging unit 7 compares the distance to the obstacle measured by the distance measuring unit 5 with a preset threshold value, and judges that a person has entered the bathroom in the following cases.

Embodiment approach 2

[0045] Figure 4 It is a block diagram explaining the remote control device of the toilet device in Embodiment 2 of this invention. The determination unit 7 has a display unit 8 , a switching unit 9 , a calibration unit 10 , and a storage unit 11 . In addition, an operation unit and a display unit corresponding to functions of the toilet device (for example, a washing function, a drying function, a deodorizing function, and a toilet seat heating function) are omitted.

[0046] Next, the operation and function will be described. The judging unit 7 has a plurality of thresholds, and these thresholds can be switched by the operation of the switching unit 9 . For example, set the threshold to a minimum (near) value when shipped from the factory. That is, in the initial state, it is set to a state in which a wall or a door is not mistakenly detected as a person even in the narrowest bathroom. In the case of installing the toilet device in a wide bathroom, etc., when the person ...

Embodiment approach 3

[0055] Figure 5 It is a perspective view of the toilet device in Embodiment 3 of the present invention, Image 6 A block diagram of the associated actions for seated control. In the toilet device of this embodiment, in addition to the configuration of Embodiment 1, a seat occupancy detection unit (hereinafter referred to as a detection unit) 33, a seated judgment unit (hereinafter referred to as a judgment unit) 34, a toilet seat state recognition unit, and a toilet seat state recognition unit are further provided in the main body 1. (hereinafter referred to as a recognition unit) 35 and a seating determination setting unit (hereinafter referred to as a setting unit) 36 . In addition, the operation box 37 is provided on the side and is in contact with the main body 1 . In addition, a setting switching button is provided on the operation box 37 to perform various settings such as setting of the temperature of the washing water sprayed from the washing water spraying unit 2 ....

Abstract

A toilet device has a distance measuring section for measuring the distance to an obstacle, and a deciding section. The deciding section compares a preset threshold value with the measured value from the distance measuring section. If the measured value from the distance measuring section is smaller than the threshold value, it is decided that a human body is present. This threshold value can be changed. In this arrangement, when a toilet device is to be installed in a large toilet room, the threshold value for the deciding section may be changed to a greater value, so that a person entering the toilet room can be immediately detected.

Description

technical field [0001] The present invention relates to a toilet device and a human body detection method capable of accurately detecting the presence position of a user. Background technique [0002] Previously, this toilet device detected the human body through a light sensor. [0003] Figure 19 The first example of a conventional toilet installation is shown in . In this toilet device, a main body 81, a toilet seat 82 connected to the main body 81 so as to be rotatable, and a cover 83 are provided. The main body 81 is provided with a control circuit (not shown in the figure), an opening and closing device (not shown in the figure) of the cover 93 , and a sensor unit 84 . The lid 83 and the toilet seat 82 are provided with openings 85 through which infrared rays projected and returned by the sensor unit 84 can pass. After the sensor unit 84 detects the presence of a person, it sends a signal to the control circuit to allow the opening and closing device of the cover 83...
