The thing of patent document 1 is the technique for preventing the dew from the human body being cooled by the toilet seat, and condensing, in order to eliminate the sticky feeling felt when sitting on the toilet seat in the summer, and toilet seat surface temperature By maintaining the temperature around 36 ° C., which is about the body temperature, the object is achieved.

The present invention relates to a toilet seat apparatus installed in an apartment house such as an apartment built for singles, having a relatively small floor area such as 1DK and 1LDK. Recently, toilets in such apartments have also been equipped with a toilet seat device in the form of a hot water washing type and a heated toilet seat. In this toilet seat device, hot water supplied to the heating unit is warmed by a hot water heater. The heated toilet seat is heated by a toilet seat heater.

In general, the owner of such an apartment is in a form of renting to a resident with a rent that includes utilities. The warm water washing type and the heating toilet seat are usually the warm water heater and the toilet seat heater,
In the model room, these electricity costs are around 500 yen per month. As an owner of an apartment house, the fact that these electricity bills are small can directly lead to profits, so there is no doubt about capital investment for that purpose.

In such apartment houses, toilets are made where there are no windows because of the layout. For this reason, it is necessary to turn on the toilet lighting when using the toilet. In summer, the temperature of the supplied water and the temperature in the toilet room are high, so that the hot water temperature and the heating toilet seat temperature may be set lower than the normal state when the toilet is not used.

In view of such a point, the present invention provides a toilet seat device that exhibits a power saving effect suitable as a housing complex. As a means for this, since the toilet illumination is normally turned on when the toilet is used, it is determined that the toilet is in use in the lighting state, and the warm water heater and the toilet seat heater are set to the normal energization mode. When the toilet lighting is turned off, it is determined that the toilet is not in use. At that time, when the ambient temperature in the toilet room is high, such as in summer, the hot water heater and the toilet seat heater are switched to a power saving mode in which the power supply rate is lower than in the normal power supply mode Thus, a technique for reducing the power consumption in the toilet seat device in the standby state is provided.

In the present invention, a toilet seat body that supports a heated toilet seat that is heated by a toilet seat heater is installed on a Western-style toilet, and the supplied water is heated by the hot water heater and heated by the heating portion. The toilet seat body includes a cleaning nozzle for injecting hot water toward a local part of the human body, and the toilet seat device performs cleaning with the cleaning nozzle by operating a switch. The toilet seat device includes a seating sensor that detects seating on the toilet seat. The toilet seat heater and the hot water heater are in a normal energization control mode (a temperature set by a user or a temperature set by a user) when the brightness detection sensor detects that the toilet room in which the toilet seat device is installed is equal to or higher than a predetermined brightness. Control at a temperature set in the device), and the ambient temperature detection sensor in the toilet room is in winter when the brightness detection sensor does not detect the predetermined brightness. A first power-saving control mode in which the toilet seat heater and the hot water heater are more energy-saving than the normal energization control mode when a temperature equal to or less than a first predetermined temperature is detected. When detecting a spring temperature higher than the first predetermined temperature and a second predetermined temperature or higher, the toilet seat heater and the hot water heater are set to a second power saving control mode in which power saving is greater than the first power saving control, and When the ambient temperature detection sensor detects a temperature higher than the second predetermined temperature and higher than a third predetermined temperature determined as a summer temperature, the toilet seat heater and the warm water heater are configured to save power greater than the second power saving control. as a control mode, when said seat sensor has passed a predetermined time after detecting the departure from human toilet seat, if the brightness sensor is detecting the brightness, the ambient temperature And you switch to one of the first to third power save mode based on the detected temperature of intellectual sensor.

In the present invention, since the brightness detection sensor detects the state in which the toilet lamp is lit, it is caught that the toilet is being used by the lighting of the toilet lamp in a toilet without a window, and the toilet seat is in the normal energization control mode. The energization control of the heater and the hot water heater is performed, and the temperature of the toilet seat and the hot water is increased to a predetermined temperature. In addition, in the present invention, when the temperature inside the toilet room is high, such as in summer, there is almost no cold feeling even if the heating temperature of the toilet seat and hot water is lowered. In this state, the power saving control mode in which the temperature of the toilet seat and the hot water is lowered is set. As a result, when the toilet lamp is turned on and toilet use is started and the power saving control mode is switched to the normal energization control mode, even if the temperature of the toilet seat and hot water does not immediately rise to the normal heating temperature due to the time lag, The person sitting on the toilet seat hardly feels cold, there is no problem in using the toilet, and rather the power saving effect when the toilet is not used is great. Moreover, even if the toilet user leaves the toilet without turning off and the toilet lamp 60 remains on, the power saving control mode can be restored.

And in order to change the control state of the power saving control mode according to the temperature conditions of the three seasons of winter, spring, autumn and summer, compared to the case where the uniform power saving control mode is performed, while not using the toilet Warm water and toilet seat warming temperature can be set according to the temperature in the toilet room, so that the warm water and toilet seat warming state can be properly maintained when the toilet is not in use .

When the cleaning stop switch 44 is pressed, the control unit 32 operates the switching elements 38 and 40 as appropriate to operate the cleaning motor 43 to return the switching valve to the initial position and close the electromagnetic valve 11. The water pressure is not applied, the ejection of the cleaning water is stopped, and the cleaning nozzle 20 or 21 that has advanced has returned by the spring force.

In the present invention, when the toilet is used, the toilet seat heater 41 and the hot water heater 42 are in the normal energization control mode (normal energization control state) by the operation of the control unit 32. In this normal energization control mode, the temperature of the hot water in the hot water tank 13 is a temperature arbitrarily set by the user by the ON operation of the temperature adjustment switch 48, and the illustrated one is for each ON operation of the temperature adjustment switch 48. The LED 48L that can be selected and set from three levels of strong (40 ° C.), medium (38 ° C.), and weak (35 ° C.) is provided. In this case, the temperature of the hot water is determined by the operation of the control unit 32 based on the detection of the hot water detection sensor 54 so that the switching element 37 turns on the energization of the hot water heater 42.
-It is controlled to this set temperature by OFF control. For this reason, the normal energization control mode can also be referred to as an energization control mode at a set temperature.

Further, in this normal energization control mode, the heating temperature of the toilet seat 4 is a temperature arbitrarily set by the user by the ON operation of the toilet seat temperature adjustment switch 49, and the illustrated one is an ON operation of the toilet seat temperature adjustment switch 49 Each can be selected and set in three stages of strong (39 ° C.), medium (37 ° C.), and weak (35 ° C.), and is equipped with an LED 49L that lights up accordingly. In this case, the temperature of the toilet seat 4 is controlled to the set temperature by the switching element 36 performing ON / OFF control of the energization of the toilet seat heater 41 by the operation of the control unit 32 based on the detection of the toilet seat temperature sensor 35. The

In the case where the temperature adjustment switch 48 and / or the toilet seat temperature adjustment switch 49 are not provided, the set temperature of the hot water and / or the set temperature of the toilet seat 4 are the temperatures set in the control unit 32, and the control in the normal energization control mode is The control is performed at the temperature set in the control unit 32.

In the present invention, the toilet seat heater 41 and the hot water heater 42 are operated by the operation of the control unit 32 so as to save power when the toilet is not used in a high temperature state such as in summer when the atmosphere temperature (air temperature) in the toilet room is high. The power saving control mode (power saving control state) is set so that the control state with the heating temperature lowered is achieved. When the toilet is not used and the ambient temperature detection sensor 50 detects a predetermined temperature or higher (for example, 25 ° C. or higher), the energization rate of the hot water heater 42 is set to one third of that in the normal energization control mode. The power saving control mode is set to two-thirds, and the power saving rate of the toilet seat heater 41 is set to one third to two thirds of the normal power supply control mode. Such a power saving control mode provides a power saving control mode in which the heating temperature by the toilet seat heater 41 and the hot water heater 42 is lowered when the toilet is not used in a high temperature state such as in summer, so that an energy saving effect is obtained. And when it becomes a toilet use state, it can maintain warm water and the toilet seat 4 in a suitable temperature state by setting it as a normal electricity supply control mode.

In this case, as one method of detecting whether the toilet is used or not, pay attention to the fact that the toilet lamp is turned on when the toilet is used, and the toilet lamp is turned off when the toilet is not used. Use / non-use can be detected by the brightness detection sensor 53. For this reason,
In this power saving control mode, when the use of the toilet is started, the toilet lamp is turned on. Therefore, the brightness detection sensor 53 detects the brightness, and the operation of the control unit 32 controls the normal energization control from the power saving control mode. The mode is switched, and the energized state of the hot water heater 42 is returned to the control state in which the temperature is arbitrarily set by the user by the ON operation of the temperature adjustment switch 48. The energized state of the toilet seat heater 41 is controlled by the toilet seat temperature adjustment. When the switch 49 is turned on, the control state returns to the temperature setting arbitrarily set by the user. By switching from the power saving control mode to the normal energization control mode, the hot water temperature returns to the normal energization control temperature, and the temperature of the toilet seat 4 returns to the normal energization control temperature. Since the time required for this return is about 1 minute, taking into account the time required to enter the toilet and sit on the toilet seat 4, there is no discomfort that feels cold when seated.

As described above, the power saving control mode is a power saving control mode in which the heating temperature by the toilet seat heater 41 and the hot water heater 42 is reduced when the toilet is not used in a high temperature state such as in summer. In the power saving control mode, when the use of the toilet is started, the mode is switched to the normal energization control mode, and the temperature of the hot water and the temperature of the toilet seat 4 rise quickly, so that the toilet seat user does not feel uncomfortable.

In addition to the above, the use / non-use of the toilet can be detected by a method for detecting the state of the ON / OFF switch of the toilet lamp, a method for detecting that a person has entered the toilet room, or a toilet seat. 4 may be any one of detection methods using a seating detection switch 33 that operates when a person is seated.

Since the temperature in the toilet room changes according to changes in the outside air temperature, the present invention provides a technique for obtaining a power saving effect according to the season. This will be described with reference to FIG. In FIG. 4, the lighting / extinguishing state of the toilet lamp 60 is detected by the brightness detection sensor 53 (S1). When the lighting of the toilet lamp 60 is detected (S2), the toilet seat heater 41 and the hot water heater 42 are in the normal energization control mode (S3) by the operation of the control unit 32. On the other hand, if the toilet lamp 60 is turned off, the brightness detection sensor 53 is not detecting the predetermined brightness (S4). In this state, the ambient temperature detection sensor 50 in the toilet room is in winter. A power-saving control mode adapted to the three seasons of winter, spring, autumn and summer is set by setting the three detection levels so as to detect the temperature according to the three seasons of spring, autumn and summer. It is comprised so that it may become.

That is, in FIG. 4, when the toilet lamp 60 is turned off (S4), the detection by the atmosphere temperature detection sensor 50 (S5) is the first predetermined temperature (for example, 5 ° C.) determined as the winter temperature.
) When the following is detected (S6), the operation of the control unit 32 sets the toilet seat heater 41 and the hot water heater 42 to the first power saving control mode in which power saving is achieved rather than the normal energization control mode. In the first power saving control mode, the toilet seat heater 41 and the hot water heater 4 in the normal energization control mode are used.
With respect to the energization of 2, the power saving control state in which the energization rates of the toilet seat heater 41 and the hot water heater 42 are two-thirds is set.

Further, in the state where the toilet lamp 60 is turned off (S4), the detection (S5) by the ambient temperature detection sensor 50 is determined to be the summer temperature at or above the second predetermined temperature (for example, 15 ° C.) determined as the spring / autumn temperature. When a temperature lower than a third predetermined temperature (for example, 20 ° C. or 25 ° C.) is detected (S7)
) By the operation of the control unit 32, the toilet seat heater 41 and the hot water heater 42 are set to the second power saving control mode in which the power saving is larger than the first power saving control. In the second power saving control mode, the power saving control state is set such that the energization rates of the toilet seat heater 41 and the hot water heater 42 are halved with respect to the energization of the toilet seat heater 41 and the hot water heater 42 in the normal energization control mode.

In the state where the toilet lamp 60 is turned off (S4), the detection (S5) by the ambient temperature detection sensor 50 detects a third predetermined temperature (for example, 20 ° C. or 2) determined as the summer temperature.
(5 ° C.) or more is detected (S8), the operation of the control unit 32 sets the toilet seat heater 41 and the hot water heater 42 to the third power saving control mode in which power saving is greater than the second power saving control. In the third power saving control mode, the toilet seat heater 41 and the hot water heater 4 in the normal energization control mode are used.
For the energization of 2, the power saving control state in which the energization rates of the toilet seat heater 41 and the hot water heater 42 are reduced to one third.

As described above, the operation of the control unit 32 switches the control state of the power saving control mode according to the temperature states of the three seasons of winter, spring, autumn, and summer, thereby saving power as compared with the case where the uniform power saving control mode is performed. While being effective, the warm water and toilet seat warming temperature when the toilet is not in use can be set according to the temperature in the toilet room, so the warm water and toilet seat can be added when the toilet is not used. The temperature state can be properly maintained. In the state where the toilet lamp 60 is turned off (S4), the detection (S5) by the ambient temperature detection sensor 50 is S
When the detection state is not 6 to S8 (S9) (for example, the ambient temperature is in the range of 6 ° C. to 14 ° C.), the normal energization control mode (S3) is set.

As described above, in the method in which whether the toilet lamp is turned on or not is detected by the brightness detection sensor 53 when the toilet is used, the toilet lamp 60 leaves the toilet without being turned off. If is kept on, even if the ambient temperature detection sensor 50 detects a temperature higher or lower than the predetermined temperature at which the power saving mode should be entered as in S6 to S8, the power saving control mode is not switched. In order to prevent this, as a first method, the seat switch 33 is activated (detected) when the seat 4 is separated from the seated toilet seat 4, so that a timer included in the control unit 32 is started and a predetermined time ( For example, when the toilet is not used again within any set time of 10 minutes to 30 minutes, the control unit 32 automatically switches to the power saving control mode after the predetermined time has elapsed. Then, when the seating switch 33 is activated (detected) so as to detect that the user has been seated again by using the toilet, the same operation as described above is performed so as to switch to the normal energization control mode.

Further, as a second method, a human sensor 55 that detects the entry / exit of a person into / from the toilet room by infrared rays is connected to the control unit 32, and power saving control is performed from the normal energization control mode based on the detection of the human sensor 55. Switching to the mode and switching from the power saving control mode to the normal energization control mode are performed, and the toilet lamp 60 is turned on / off. In this way,
A manual switch for turning on / off the toilet lamp 60 is also unnecessary, and based on the detection of the human sensor 55, based on the exit of the person from the toilet room, the controller 32 forcibly enters the power saving control mode. It will be switched. Then, when the human sensor 55 detects the entry of a person again by using the toilet, similarly to the above, it operates so as to switch to the normal energization control mode.

The control unit 32 is a microcomputer control system that operates according to a predetermined program so that all the operations in S1 to S9 are performed periodically.

In the state where the control operation as described above is performed, when sitting on the toilet seat 4 in a drunken state, there is a possibility that the sitting time on the toilet seat may become longer, in which case the normal energization control mode is long. There is a risk that the seated person may get a low temperature burn. In order to prevent this, if the normal energization control mode is a predetermined time or longer (for example, any time between 30 minutes and 60 minutes), the timer of the control unit 32 reduces the heat generation of the toilet seat heater 41. Or turn off the power. In this method, the timer is activated from when the seating switch 33 detects the seating, and when the predetermined time (30 to 60 minutes) has elapsed, the heat generation of the toilet seat heater 41 is automatically reduced or turned off. Switch to power saving control mode. This has the effect of preventing low temperature burns when the sitting time is long. If the toilet is not used, the seat switch 33 is activated (detected) when the toilet seat 4 is separated from the seated seat 4, so that the toilet seat heater 41 and the hot water heater 42 are placed in the power saving control mode.
