Problems solved by technology

However, in the standby state (for example, a state in which the user does not enter the restroom), which is the longest state, the temperature of the toilet seat is controlled without considering the environmental conditions in the restroom.
Therefore, actually, unnecessary power consumption may be generated depending on the environmental conditions, for example, the temperature of the toilet seat is kept higher than the value set as the standby state temperature, etc.

Embodiment approach 1

[0039] The appearance of the toilet seat device

[0040] figure 1 Is a perspective view of the toilet seat device according to the first embodiment of the present invention, figure 2 Is a schematic structure diagram, image 3 Is a partial cutaway plan view of the toilet seat of this embodiment, Figure 4 It is a cross-sectional view of the main part of the upper part of the toilet seat.

[0041] Such as figure 1 As shown, a main body 21 is installed on the upper surface of the toilet 20, and a toilet seat 22 and a toilet cover 23 are provided on the main body 21 in a rotatable manner.

[0042] An infrared sensor unit 24 is provided on the side of the main body 21 to receive infrared signals from an operation remote control (not shown) and a human body detection unit (sitting intention detection unit) 25. The human body detection unit 25 is composed of, for example, a pyroelectric sensor and an infrared light emitting unit, and when a human body is detected in the toilet space, it t...

Embodiment approach 2

[0131] Picture 11 It is a configuration diagram of a toilet seat device with a warm water washing function according to Embodiment 2 of the present invention. The difference from Embodiment 1 is that a drying function unit 55 that blows warm air to the cleaned part is provided.

[0132] The control unit 50 performs output control of the drying heater 57 and the drying fan 58 based on the signal from the room temperature detection sensor 56. In addition, the same temperature sensor is used to control the temperature of the toilet seat (including the control of the energization rate during the standby period) and the temperature control of the drying. Therefore, there is no need to install a temperature sensor dedicated to toilet seat control. As in the first embodiment, a simple structure can be achieved. , Low cost, high precision toilet seat temperature control.

Embodiment approach 3

[0134] Picture 12 It is a configuration diagram of a toilet seat device with a warm water washing function according to Embodiment 3 of the present invention. The difference from Embodiments 1 and 2 is that a room temperature detection sensor 59 is provided inside the human body detection unit 25. The human body detection unit 25 transmits a signal from the room temperature detection sensor 59 to the control unit 50 of the main body 21 through an infrared light emitting unit. The human body detection unit 25 corrects the sensitivity and output of the human body detection sensor based on the signal from the room temperature detection sensor 59.

[0135] In addition, the same room temperature detection sensor 59 is used to perform temperature control of the toilet seat (including control of the energization rate during the standby period) and calibration of the human body detection sensor of the human body detection unit 25, thereby eliminating the need to install a temperature se...

Abstract

A toilet seat device which attains energy saving by furthermore reducing power consumption when adjusting the temperature of a toilet seat, without damaging comfort of a toilet user. A control section provided to the toilet seat device controls distribution of power to a heat generator (29) such that in a standby state the temperature of the toilet seat (22) detected by a toilet seat temperature detection means (44) is a predetermined standby temperature and such that when detecting information relating to a user's intention to seat on the toilet seat (22), the temperature of the toilet seat (22) rises at a predetermined speed from the standby temperature to a temperature higher than the standby temperature and within a seating temperature range wherein seating of the user on the toilet seat (22) is assumed. Furthermore, the distribution of power to the heat generator (29) in the standby state is varied in accordance with the temperature in a toilet room detected by a second temperature detection means (48).

Description

Technical field [0001] The present invention relates to temperature control of the seating part of the toilet seat of the toilet seat device. Background technique [0002] Conventionally, regarding this type of toilet seat device, a device has been proposed that has various functions of adjusting the temperature of a part directly contacted by the human body to an appropriate temperature in order not to cause discomfort to the human body. Among them, a method of controlling the temperature of the seat portion of the toilet seat is further proposed so that the user can sit on the toilet seat comfortably even in low temperature conditions such as winter (for example, refer to Patent Document 1). [0003] The toilet seat device described in Patent Document 1 includes a toilet seat temperature detection unit that detects the temperature of the toilet seat provided on the back of the toilet seat, a room temperature detection sensor that detects room temperature, a heating element provid...
