Description
Technical Field
The present invention relates to a toilet seat apparatus.
Background
Conventionally, as such a toilet device, there has been proposed a toilet device including a heater for heating a toilet seat, in which the operating time of the heater is detected, the frequency of use of each time slot is counted, the temperature is set in each time slot according to the frequency of use of each time slot, and the amount of heat generated by the heater is controlled based on the set temperature (see, for example, patent document 1).

Patent document 2: japanese patent laid-open publication No. 2018-15207
Problems to be solved by the invention
In the toilet apparatus described in patent document 1, although power consumption can be suppressed in a time zone with a low frequency of use, when a user sits on the toilet during the time zone, the toilet does not warm up, and discomfort is given to the user. On the other hand, in the toilet seat apparatus described in patent document 2, the toilet seat is kept on standby at a standby temperature at ordinary times, and when the user is detected, the temperature of the toilet seat is raised from the standby temperature to a set temperature. However, there are various times from when the user enters the toilet room to when the user actually sits on the toilet seat, and when the user entering the toilet room sits faster than expected, the toilet seat does not get sufficiently warm, and therefore the user may feel uncomfortable.
Disclosure of Invention
The main object of the present invention is to provide a toilet seat device capable of balancing comfort and power saving performance well in a heating toilet seat.
Means for solving the problems
To achieve the above main object, the toilet seat apparatus of the present invention adopts the following means.
A first toilet seat apparatus according to the present invention is a toilet seat apparatus having a toilet seat, and includes:
a heating device for heating the toilet seat;
a user detection sensor that detects a user; and
a control device that selects and executes any one of a plurality of modes including a normal mode in which the heating device is controlled to heat the toilet seat based on a set temperature set by a user, and a detected temperature rise mode in which: when the user is not detected by the user detection sensor, the heating device is controlled by using a temperature lower than the set temperature as a standby temperature or the heating device is turned off, and when the user is detected by the user detection sensor, the heating device is controlled based on the set temperature so as to warm the toilet seat.
In the first toilet seat apparatus of the present invention, any one of a plurality of modes including a normal mode and a temperature increase detection mode is selected and executed, the normal mode is a mode in which the heating apparatus is controlled to heat the toilet seat based on a set temperature set by a user, and the temperature increase detection mode is a mode in which: when the user is not detected by the user detection sensor, the heating device is controlled to be at a temperature lower than the set temperature or to be turned off, and when the user is detected by the user detection sensor, the heating device is controlled to be heated based on the set temperature. In the normal mode, the heating device is controlled based on the set temperature, so that comfort is easily ensured, but wasteful power consumption may occur during a time period of infrequent use. In contrast, in the detected temperature rise mode, when the user is detected, the heating device is controlled based on the standby temperature lower than the set temperature, so that the power saving performance is easily ensured, but when the user who enters the toilet room sits on the toilet seat earlier than expected, the temperature cannot be raised to the set temperature in time, and the comfort may be impaired. Therefore, comfort and power saving performance can be well balanced by selecting and executing the normal mode and the detected warm-up mode as needed.
In the first toilet seat apparatus according to the present invention, the control device may learn the frequency of use of the toilet seat in advance for each time period, select the normal mode in a time period in which the frequency of use of the toilet seat is equal to or higher than a predetermined frequency, and select the detected temperature increase mode in a time period in which the frequency of use of the toilet seat is lower than the predetermined frequency. That is, the normal mode is selected in priority of user comfort in the time zone of frequent use, and the temperature increase detection mode is selected in priority of power saving performance in the time zone of infrequent use. Thus, the comfort and power saving performance of the user can be more well balanced.
In the first toilet seat apparatus according to the aspect of the invention, as the detected temperature increase mode, the control device may control the heating device such that the standby temperature is lower when the frequency of use of the toilet seat is low than the predetermined frequency, than when the frequency of use of the toilet seat is high. In this way, in the detected temperature increase mode, the power saving performance can be further improved while ensuring comfort to some extent.
The second toilet apparatus of the present invention includes:
a heating device for heating the toilet seat;
a user detection sensor that detects a user; and
a control device that selects and executes any one of a plurality of modes including a learning mode and a detected temperature increase mode, the learning mode being as follows: learning the frequency of use of the toilet seat in advance for each time period, controlling the heating device to heat the toilet seat based on a set temperature set by a user in a time period in which the frequency of use of the toilet seat is equal to or higher than a predetermined frequency, controlling the heating device to heat the toilet seat based on a temperature lower than the set temperature or turning off the heating device in a time period in which the frequency of use of the toilet seat is lower than the predetermined frequency, wherein the detected temperature rise pattern is a pattern as follows: when the user is not detected by the user detection sensor, the heating device is controlled by using a temperature lower than the set temperature as a standby temperature or the heating device is turned off, and when the user is detected by the user detection sensor, the heating device is controlled based on the set temperature so as to warm the toilet seat.
In the second toilet seat apparatus of the present invention, any one of a plurality of modes including a learning mode and a temperature increase detection mode is selected and executed, and the learning mode is a mode as follows: the frequency of use of the toilet seat is learned in advance by time intervals, and the heating device is controlled to heat the toilet seat based on a set temperature set by a user in a time interval in which the frequency of use of the toilet seat is equal to or higher than a predetermined frequency, and the heating device is controlled to heat the toilet seat based on a temperature lower than the set temperature in a time interval in which the frequency of use of the toilet seat is lower than the predetermined frequency. In the learning mode, the heating device is controlled based on the set temperature in the frequently used period, the heating device is controlled based on the temperature lower than the set temperature in the infrequently used period, or the heating device is turned off, so that it is easy to ensure comfort immediately after sitting, but the shorter the infrequent period, the lower the power saving performance. In contrast, in the detected temperature rise mode, when the user is not detected, the heating device is controlled based on the temperature (standby temperature) lower than the set temperature, and when the user is detected, the heating device is controlled based on the set temperature to rise the temperature, so that there is a possibility that the user does not reach the temperature rise immediately after sitting and the comfort is impaired, but if the number of uses is not so large, the reduction in the power saving performance can be suppressed even if the period of infrequent use is short. Therefore, by appropriately selecting and executing the learning mode and the detected temperature increase mode, comfort and power saving performance can be balanced.
In the second toilet apparatus according to the present invention, the control device may predict one of the learning mode and the detected temperature increasing mode in which the power consumption amount or the power rate decreases for a predetermined period of time, and select the predicted mode. This can ensure comfort to some extent, and further improve power saving performance or suppress electric power consumption.
In the first or second toilet seat apparatus according to the aspect of the invention in which the usage frequency of the toilet seat is learned for each time zone, the control device may control the heating device to heat the toilet seat based on the temperature higher than the set temperature in a time zone in which the usage frequency of the toilet seat is higher than or equal to a second predetermined frequency higher than the predetermined frequency when the set temperature is lower than or equal to the predetermined temperature. Thus, even when the user personally lowers the set temperature, the user can be prevented from being given a significant feeling of discomfort during a time period when the frequency of use is particularly high.
A third toilet apparatus according to the present invention is a toilet apparatus having a toilet seat, including:
a heating device for heating the toilet seat;
a user detection sensor that detects a user; and
a control device that controls the heating device with a temperature lower than a set temperature set by a user as a standby temperature and controls the heating device to warm up the toilet seat when the user is detected by the user detection sensor,
the control device learns the frequency of use of the toilet seat in a time-divided manner, and controls the heating device by setting a lower temperature as the standby temperature when the frequency of use of the toilet seat is high than when the frequency of use of the toilet seat is low.

Detailed Description
The embodiments for carrying out the present invention will be described with reference to the drawings.
Fig. 1 is an external perspective view showing an external appearance of a toilet seat apparatus 10 according to a first embodiment of the present invention, and fig. 2 is a schematic configuration diagram showing configurations of a toilet seat heater 20 and a control device 30. As shown in fig. 1, the toilet apparatus 10 is attached to the upper surface of the toilet 1. The toilet device 10 includes: a toilet seat device main body 12; a toilet seat 14 supported to be openable and closable with respect to the toilet seat apparatus main body 12; a toilet seat heater 20 disposed on the back side of the seat surface 14a of the toilet seat 14; a toilet cover 16 supported so as to be openable and closable with respect to the toilet apparatus main body 12 and provided so as to cover the toilet seat 14 when fully closed; and a remote control device (hereinafter, referred to as a remote control) 18 that can be operated by a user.
As shown in fig. 2, the toilet seat apparatus main body 12 includes: a control device 30 for controlling each part of the toilet seat main body 12; a toilet seat temperature sensor 22 for detecting the temperature of the toilet seat 14 (in the vicinity of the seat surface 14 a); an infrared entry detection sensor 24 for detecting entry of a user into a toilet room in which the toilet 1 is disposed; an infrared type seating detection sensor 26 for detecting seating of a user on the seating surface 14a of the toilet seat 14; and an outside air temperature sensor 28 that detects an outside air temperature Ta. The toilet seat apparatus main body 12 is provided with a jet nozzle for jetting washing water for washing the private parts of the human body, a hot water heater for heating the washing water supplied to the jet nozzle, and the like, although not shown.
The remote controller 18 includes, for example, a hip flush switch for instructing to start hip flushing, a private part flush switch for instructing to start private part flushing, a stop switch for instructing to stop each flushing, a water potential setting switch for setting the water potential of the flush water, a flush position setting switch for setting the flush position, a water temperature setting switch for setting the temperature of the flush water, a large flush switch for instructing to flush the inside of the toilet 1, a small flush switch, and the like. The remote controller 18 further includes a toilet seat temperature setting switch 18a for setting the temperature (set temperature Ts) of the seat surface 14a of the toilet seat 14. In the present embodiment, the set temperature Ts is set by selecting one of the off (heating off), low setting (low temperature), medium setting (medium temperature), and high setting (high temperature) by the toilet seat temperature setting switch 18 a.
The toilet seat heater 20 is a momentary heating type heater capable of heating the toilet seat 14 to the set temperature Ts set by the remote controller 18 in a predetermined short time (several seconds to ten seconds), and has a rated output of about several hundred W such as 300 to 800W, for example.
The control device 30 is a microprocessor including a CPU32 as a center, and includes a ROM34 for storing processing programs, a RAM36 for temporarily storing data, an rtc (real Time clock)38 for timing, and the like in addition to the CPU 32. An operation signal from the remote controller 18, a detection signal (toilet seat temperature) from the toilet seat temperature sensor 22, a detection signal (entry signal) from the entry detection sensor 24, a detection signal (seating signal) from the seating detection sensor 26, and the like are input to the control device 30. The control device 30 outputs a control signal to be input to the jet nozzle, a control signal to be input to the toilet seat heater 20, a control signal to be input to the hot water heater, and the like.
Next, the operation of the toilet seat device 10 configured as described above, particularly, the operation (toilet seat heating control) when the toilet seat heater 20 heats the toilet seat 14 will be described. In the present embodiment, the toilet seat heating control includes a normal mode and a quick heating mode as the control modes. Here, the normal mode is basically the following mode: the set temperature Ts set by the seat temperature setting switch 18a is set to the target temperature T, and the seat heater 20 is controlled to heat the seat 14 at the set target temperature T. In addition, the rapid heating mode is as follows: when the entry detection sensor 24 does not detect that the user enters the toilet room, the standby temperature Tw lower than the set temperature Ts set by the toilet seat temperature setting switch 18a is set to the target temperature T, and the toilet seat heater 20 is controlled to heat the toilet seat 14 at the set target temperature T, and when the entry detection sensor 24 detects that the user enters the toilet room, the set temperature Ts is set to the target temperature T, and the toilet seat heater 20 is controlled to heat the toilet seat 14 at the set target temperature T. In the present embodiment, the normal mode and the rapid heating mode are selected for each time zone based on the frequency F of use of the toilet in different time zones. Fig. 3 is a flowchart showing an example of the use frequency learning process executed by control device 30, and fig. 4 is a flowchart showing a toilet seat heating control process. Here, the use frequency learning process is repeatedly executed every predetermined period (for example, every day, every three days, every week) when the power supply is turned on. The toilet seat heating control process is repeatedly executed at predetermined time intervals (for example, every several milliseconds, every ten and several milliseconds). First, the usage frequency learning process will be described, and then the toilet seat heating control process will be described.
In the use frequency learning process, the CPU32 of the control device 30 first waits for the seating detection sensor 26 to detect a change from seating to unseating (or from unseating to seating) of the user from the toilet seat 14 (step S100). When a change from seating to unseating of the toilet seat 14 is detected, the current time t from the RTC38 is input (step S110), and the number of times of use of the time zone to which the input current time t belongs is updated incrementally by a numerical value of 1 (step S120). Here, the time zone to which the current time t belongs is a time zone obtained by dividing one day by a predetermined time (for example, one hour or two hours). Then, it is determined whether or not a predetermined period of time has elapsed since the start of the present process (step S130). Here, the predetermined period is a learning period for learning the frequency of use of the toilet, and can be defined as, for example, one day, three days, one week, or the like. If it is determined that the predetermined period has not elapsed, the process returns to step S100. On the other hand, when it is determined that the predetermined period has elapsed, the frequency of use F for each time zone is set based on the number of times of use for each time zone (step S140), and is registered in the predetermined area of the RAM36 (step S150), and the present process is ended. Here, in the present embodiment, the use frequency F is set by determining which of a low frequency (for example, the number of uses is zero, that is, unused), a medium frequency (for example, the number of uses is one to two), a high frequency (for example, the number of uses is three to five), and a high frequency (for example, the number of uses is six or more). In the present embodiment, the low frequency is set to be unused, but may be included only a few times, for example, once, depending on the length of the unit time zone.
In the toilet seat heating control process, the CPU32 of the control device 30 first inputs the current time t from the RTC38 (step S200). Then, the usage frequency F of the time zone to which the current time t has been input is read from the RAM36 (step S210), and it is determined whether the read usage frequency F is high frequency or high frequency (predetermined frequency or higher) (step S220). When it is determined that the frequency F of use of the current time zone is high or high, the normal mode is selected as the mode to be executed at the current time t (step S230), and the present process is ended, and when it is determined that the frequency F of use of the current time zone is medium or low (less than a predetermined frequency), the rapid heating mode is selected as the mode to be executed at the current time t (step S240), and the present process is ended. Here, the normal mode is executed by the normal mode process illustrated in fig. 5, and the rapid heating mode is executed by the rapid heating mode process illustrated in fig. 6.
In the normal mode processing, the CPU32 first inputs the set temperature Ts from the toilet seat temperature setting switch 18a and the current time t from the RTC38 (step S300), and determines whether or not the input set temperature Ts is a low setting (step S310). When it is determined that the set temperature Ts is set low, the use frequency F of the time zone to which the input current time t belongs is read from the RAM36 (step S320), and it is determined whether or not the read use frequency F is high frequency (step S330). If it is determined in step S310 that the set temperature Ts is not low but medium or high, or if it is determined in step S310 that the set temperature Ts is low but the use frequency F is not high but high, the set temperature Ts is set to the target temperature T (step S340). On the other hand, when it is determined that the set temperature Ts is low and the use frequency F is high in step S330 in step S310, the temperature obtained by adding the predetermined temperature Δ T to the set temperature Ts is set as the target temperature T (step S350). When the target temperature T is set in this manner, the toilet seat heater 20 is controlled to heat the toilet seat 14 at the set target temperature T (step S360), and the process is ended. The control of the toilet seat heater 20 is performed by generating a control signal (duty) by feedback control so that the toilet seat temperature detected by the toilet seat temperature sensor 22 becomes the target temperature T, and controlling the energization of the toilet seat heater 20 in accordance with the generated signal. In the present embodiment, as described above, in the normal mode, the target temperature T is basically set to the set temperature Ts set by the user, but when the set temperature Ts is set low and the frequency of use F is high, the target temperature T is set to a temperature higher than the set temperature Ts as an exception. This is because, even when the user sets the set temperature Ts to a low setting in person, the user does not feel a significant sense of discomfort during a period in which the frequency of use F is particularly high.
In the rapid heating mode processing, the CPU32 first inputs the set temperature Ts from the toilet seat temperature setting switch 18a, the outside air temperature Ta from the outside air temperature sensor 28, and the current time t from the RTC38 (step S400), and determines whether or not entry of a user into the toilet room has been detected by the entry detection sensor 24 (step S410). When it is determined that the entry is not detected, the use frequency F of the time zone to which the input current time t belongs is read from the RAM36 (step S420), and the standby temperature Tw is set based on the input set temperature Ts, the input outside air temperature Ta, and the read use frequency F (step S430). Here, in the present embodiment, the relationship between the set temperature Ts, the outside air temperature Ta, the use frequency F, and the standby temperature Tw is obtained in advance and stored in the ROM34 as a standby temperature setting map, and when the set temperature Ts, the outside air temperature Ta, and the use frequency F are given, the corresponding standby temperature Tw is derived, and the standby temperature Tw is set. Fig. 7 shows an example of a standby temperature setting map. Fig. 7(a) shows a relationship between the set temperature Ts, the outside air temperature Ta, and the standby temperature Tw when the use frequency F is a medium frequency, and fig. 7(b) shows a relationship between the set temperature Ts, the outside air temperature Ta, and the standby temperature Tw when the use frequency F is a low frequency. As described above, when the frequency of use F is high, the normal mode is selected, and therefore the standby temperature setting map is not prepared. In the standby temperature setting map in the figure, the outside air temperature Ta is divided into three stages of low temperature (e.g., less than 10 ℃), medium temperature (e.g., 10 ℃ or more and less than 20 ℃), and high temperature (e.g., 20 ℃ or more), the set temperature Ts is divided into three stages of low setting, medium setting, and high setting, the use frequency F is divided into two stages of medium frequency and low frequency, and the standby temperature Tw is set based on a combination of each of the outside air temperature Ta, the set temperature Ts, and the use frequency F. The number of divisions of the outside air temperature Ta, the set temperature Ts, and the use frequency F is not limited to this, and may be any number as long as each is 2 or more. In the standby temperature setting map, the standby temperature Tw is set to be lower when the outside air temperature Ta is high than when the outside air temperature Ta is low, to be higher when the set temperature Ts is high than when the set temperature Ts is low, and to be higher when the use frequency F is high than when the use frequency F is low. In the present embodiment, the standby temperature Tw is set by setting any one of standby 1, standby 2, standby 3, standby 4, and off. In the figure, the standby temperatures Tw of the standby 1, the standby 2, the standby 3, and the standby 4 are set to standby 1, standby 2, standby 3, and standby 4 in order from the higher temperature side. In the present embodiment, the standby state 2 is set to a temperature equal to the low setting of the set temperature Ts. When the standby temperature Tw is set in this manner, the set standby temperature Tw is set to the target temperature T (step S440), and the toilet seat heater 20 is controlled to heat the toilet seat 14 at the target temperature T (step S460), and the process is terminated. When it is determined in step S410 that the entry into the room is detected, the inputted set temperature Ts is set to the target temperature T (step S450), and the toilet seat heater 20 is controlled to heat the toilet seat 14 at the set target temperature T (step S460), and the process is ended.
Fig. 8 is an explanatory diagram showing a state of a temporal change in the target temperature for each outside air temperature in the case where the set temperature is set to a high level, fig. 9 is an explanatory diagram showing a state of a temporal change in the target temperature for each outside air temperature in the case where the set temperature is set to a medium level, and fig. 10 is an explanatory diagram showing a state of a temporal change in the target temperature for each outside air temperature in the case where the set temperature is set to a low level. As shown in the figure, when the use frequency F is a high frequency or a high frequency (a predetermined frequency or higher), the normal mode is set as the control mode of the toilet seat heating control, and the set temperature Ts is set as the target temperature T. However, when the set temperature Ts is set low in the normal mode, only when the frequency of use F is particularly high and the outside air temperature Ta is relatively low or medium, a temperature higher than the set temperature Ts is set as the target temperature T so as not to give a significant uncomfortable feeling to the user (see fig. 10(a) and 10 (b)). When the usage frequency F is a medium frequency or a low frequency (less than a predetermined frequency), the rapid heating mode is set to the control mode. In the rapid heating mode, when the user is not detected by the entry detection sensor 24, the standby temperature Tw lower than the set temperature Ts is set to the target temperature T, and when the user is detected by the entry detection sensor 24, the set temperature Ts is set to the target temperature T. The standby temperature Tw in the rapid heating mode is set to be lower when the outside air temperature Ta is high than when the outside air temperature Ta is low, and to be higher when the frequency of use F is high than when the frequency of use F is low.
In this way, in the normal mode, the toilet seat heater 20 is basically controlled based on the set temperature Ts, and thus comfort is easily ensured, but wasteful power consumption may occur during a time period of infrequent use. On the other hand, in the quick heating mode, the toilet seat 14 is kept on standby at the standby temperature Tw lower than the set temperature Ts at ordinary times, and therefore, the power saving performance is easily ensured, but when the user who enters the toilet room sits on the toilet seat 14 earlier than expected, the toilet seat 14 may not be warmed up in time, and the comfort may be impaired. In the present embodiment, since the normal mode and the rapid heating mode are appropriately selected and executed in accordance with the use frequency F, comfort and power saving performance can be well balanced.
In the toilet seat device 10 according to the first embodiment described above, either the normal mode in which the toilet seat heater 20 is controlled to heat the toilet seat 14 based on the set temperature Ts set by the user or the quick heating mode in which: when the user is not detected by the entry detection sensor 24, the toilet seat heater 20 is controlled based on the standby temperature Tw lower than the set temperature Ts, or the toilet seat heater 20 is turned off, and when the user is detected by the entry detection sensor 24, the toilet seat heater 20 is controlled to increase the temperature from the standby temperature Tw to the set temperature Ts. By selecting and executing the normal mode and the detected temperature increase mode as needed, comfort and power saving performance can be well balanced.
In the toilet apparatus 10 according to the first embodiment, the frequency F of use of the toilet is learned in advance for each time zone, and the normal mode is selected and executed in the time zone (high frequency, high frequency time zone) in which the frequency F of use is equal to or higher than the predetermined frequency (high frequency), and the rapid heating mode is selected and executed in the time zone (medium frequency, low frequency time zone) in which the frequency F of use is lower than the predetermined frequency. That is, the normal mode is selected in priority of user comfort during the time period of frequent use, and the rapid heating mode is selected in priority of power saving performance during the time period of infrequent use. Thus, the comfort and power saving performance of the user can be more well balanced.
Further, in the toilet seat apparatus 10 according to the first embodiment, since the standby temperature Tw is set lower in a case where the frequency of use F of the toilet is low (low frequency) than in a case where the frequency of use F of the toilet is high (medium frequency), the comfort can be ensured to some extent and the power saving performance can be further improved.
In addition, when the set temperature Ts is set to be low, the toilet seat heater 20 is controlled to heat the toilet seat 14 based on a temperature higher than the set temperature Ts during a high frequency period in which the frequency F of use of the toilet is particularly high. Thus, even when the user personally lowers the set temperature, the user can be prevented from being given a significant feeling of discomfort during a time period when the frequency of use is particularly high.
In the first embodiment, the normal mode and the quick heating mode are switched according to the use frequency F, but a changeover switch operated by a user may be provided, and the normal mode and the quick heating mode are switched based on the operation of the changeover switch.
In the first embodiment, in the normal mode, when the set temperature Ts is a low set (not higher than a predetermined temperature), the toilet seat heater 20 is controlled to heat the toilet seat 14 based on a temperature higher than the set temperature Ts during a high frequency period in which the frequency F of use of the toilet room is particularly high. However, the toilet seat heater 20 may be controlled based on the set temperature Ts regardless of the set temperature Ts.
In the first embodiment, in the rapid heating mode, the standby temperature Tw is set to be lower when the outside air temperature Ta is high than when the outside air temperature Ta is low, to be higher when the set temperature Ts is high than when it is low, and to be higher when the usage frequency F is high than when it is low. However, the standby temperature Tw may be set independently of the outside air temperature Ta. The standby temperature Tw may be set regardless of the frequency of use F. Further, the standby temperature Tw may be set independently of the set temperature Ts.
The toilet seat apparatus 10 of the second embodiment has the learning mode and the above-described quick heating mode as the modes of the toilet seat heating control. The learning mode is basically the following mode: the toilet seat heater 20 is controlled to heat the toilet seat 14 based on the set temperature Ts in a time zone in which the frequency F of use of the toilet is equal to or higher than a predetermined frequency (medium frequency, high frequency, or high frequency), and the toilet seat heater 20 is controlled to heat the toilet seat 14 based on a temperature lower than the set temperature Ts in a time zone in which the frequency F of use is lower than the predetermined frequency (low frequency). Note that the frequency of use F of the toilet in each time zone can use the content learned by the frequency of use learning process in fig. 3 described above.
Fig. 11 is a flowchart showing the toilet seat heating control process according to the second embodiment. In the toilet seat heating control process of the second embodiment, the CPU32 of the control device 30 first reads the frequency of use F for each time zone from the RAM36 (step S500). Then, the unused time tl (low frequency time) is calculated by summing the time periods in which the use frequency F is unused (low frequency) based on the read use frequency F of each time period (step S510), and it is determined whether or not the calculated unused time tl is greater than the predetermined time tref (step S520). When it is determined that the unused time tl is longer than the predetermined time tref, the learning mode is selected as the control mode for the toilet seat heating control (step S530), and the present process is ended, and when it is determined that the unused time tl is equal to or shorter than the predetermined time tref, the rapid heating mode is selected as the control mode (step S540), and the present process is ended. The prescribed time tref is explained later.
The learning mode is executed by the learning mode processing shown in fig. 12. In the learning mode processing, the CPU32 first inputs the set temperature Ts from the toilet seat temperature setting switch 18a and the current time t from the RTC38 (step S600). Next, the usage frequency F of the time zone to which the input current time t belongs is read from the RAM36 (step S610), and it is determined whether or not the usage frequency F is low frequency (less than a predetermined frequency) (step S620), and whether or not the usage frequency F is high frequency or higher (higher than a second predetermined frequency higher than the predetermined frequency) (step S630). When it is determined that the use frequency F is higher than or equal to the high frequency, it is further determined whether the set temperature Ts is set low (step S640). If it is determined in steps S620 and S630 that the use frequency F is not lower than the low frequency or higher than the high frequency, that is, if it is determined as the medium frequency, the inputted set temperature Ts is set as the target temperature T (step S650). If it is determined in step S620 that the use frequency F is low, the target temperature T is set based on the input set temperature Ts and the outside air temperature Ta (step S660). Here, in the present embodiment, the relationship between the set temperature Ts, the outside air temperature Ta, and the target temperature T is obtained in advance and stored as a target temperature setting map in the ROM34, and when the set temperature Ts and the outside air temperature Ta are given, the corresponding target temperature T is derived, and the target temperature T is set. Fig. 13 shows an example of a target temperature setting map. In the time zone where the use frequency F is a low frequency, as shown in the figure, the target temperature T is set to a temperature lower than the set temperature Ts, and is set to be lower when the outside air temperature Ta is high than when the outside air temperature Ta is low. In the present embodiment, in a time zone in which the use frequency F is a low frequency, any of a low temperature, a low-low temperature (a temperature lower than the low temperature), and a shut-off (heating off) is set, and the target temperature T is set. When it is determined in steps S630 and S640 that the use frequency F is not less than the high frequency and the set temperature Ts is low, a temperature obtained by adding the predetermined temperature Δ T to the set temperature Ts is set as the target temperature T (step S660). When the target temperature T is set in this manner, the toilet seat heater 20 is controlled to heat the toilet seat 14 at the set target temperature T (step S670), and the process is ended. In the present embodiment, as described above, in the learning mode, basically, when the frequency of use F is not low, the target temperature T is set to the set temperature Ts set by the user, but when the set temperature Ts is low and the frequency of use F is higher than or equal to high, the target temperature T is set to a temperature higher than the set temperature Ts as an exception. This is because, even when the user sets the set temperature Ts to a low setting in person, the user does not feel a significant sense of discomfort during a period in which the frequency of use F is particularly high.
Here, in the learning mode, the toilet seat heater 20 is controlled at a temperature lower than the set temperature Ts in the infrequently used time period, and the toilet seat heater 20 is controlled based on the set temperature Ts in the frequently used time period, so that the comfort immediately after sitting on the toilet seat 14 is easily ensured, but the shorter the infrequently used time period, the lower the power saving performance is. On the other hand, in the rapid heating mode, when the user is not detected, the toilet seat heater 20 is controlled to a temperature (standby temperature Tw) lower than the set temperature Ts, and when the user is detected, the toilet seat heater 20 is controlled to increase the temperature to the set temperature Ts. In the present embodiment, when the unused time tl is longer than the predetermined time tref, it is determined that the power saving performance in the learning mode is higher than that in the rapid heating mode, and the learning mode is selected, and when the unused time tl is shorter than or equal to the predetermined time tref, it is determined that the power saving performance in the rapid heating mode is higher than that in the learning mode, and the rapid heating mode is selected. This can ensure comfort to some extent and improve power saving performance. For the predetermined time tref, for example, the learning mode and the rapid heating mode are experimentally performed while gradually increasing or decreasing the unused time tl, the power consumption amount in each of the two modes is measured, and the unused time tl when the magnitude of the power consumption amount in each of the two modes is inverted is derived as the predetermined time tref based on the measurement result.
In the toilet seat apparatus according to the second embodiment described above, any one of a plurality of modes including the learning mode in which the frequency F of use of the toilet room in each time zone is learned in advance, and the toilet seat heater 20 is controlled based on the set temperature Ts set by the user in a time zone in which the frequency F of use is equal to or higher than a predetermined frequency (equal to or higher than a middle frequency), and the toilet seat heater 20 is controlled based on the standby temperature Tw lower than the set temperature Ts in a time zone in which the frequency F of use is lower than the predetermined frequency (lower frequency) is selected and executed. By appropriately selecting and executing the learning mode and the detected temperature increase mode as needed, comfort and power saving performance can be well balanced.
In the toilet apparatus according to the second embodiment, the learning mode is selected when the unused time tl is longer than the predetermined time tref, and the quick heating mode is selected when the unused time tl is shorter than the predetermined time tref. In the learning mode, the shorter the period of infrequent use is, the lower the power saving performance is, but in the rapid heating mode, the power saving performance is not reduced so much even if the period of infrequent use is short, so by selecting and executing one of the learning mode and the rapid heating mode in which the amount of power consumed or the electricity rate becomes small for a certain period of time, it is possible to ensure comfort to some extent and further improve the power saving performance.
Further, in the toilet seat apparatus according to the second embodiment, in the learning mode, when the set temperature Ts is a low set (not higher than the predetermined temperature), the toilet seat heater 20 is controlled to heat the toilet seat 14 based on a temperature higher than the set temperature Ts in a time zone in which the frequency of use F of the toilet is higher than or equal to a high frequency. Thus, even when the user lowers the set temperature himself/herself, the user can be prevented from being given a significant feeling of discomfort during a time period in which the frequency of use is high.
In the second embodiment, the learning mode and the quick heating mode are switched according to the low frequency time tl, but a switch operated by the user may be provided and the learning mode and the quick heating mode are switched based on the operation of the switch.
In the second embodiment, in the learning mode, when the set temperature Ts is a low setting (a predetermined temperature or lower), the toilet seat heater 20 is controlled to heat the toilet seat 14 based on a temperature higher than the set temperature Ts in a time zone in which the frequency F of use of the toilet room is higher than or equal to a high frequency. However, the toilet seat heater 20 may be controlled based on the set temperature Ts regardless of whether the set temperature Ts is set low or not.
In the second embodiment, in the learning mode, the target temperature T of the period in which the use frequency F is a low frequency is lower than the set temperature Ts, and is set to be lower when the outside air temperature Ta is high than when the outside air temperature Ta is low. However, the target temperature T at this time may be set independently of the outside air temperature Ta.
In the second embodiment, the learning mode is selected when the unused time tl is longer than the predetermined time tref, and the rapid heating mode is selected when the low frequency time tl is equal to or shorter than the predetermined time tref. However, for example, in the learning mode, the power consumption amount in the learning mode for a predetermined period may be calculated based on the target temperature T of the toilet seat 14 set according to the frequency F of use of the toilet for each time zone and the power consumption amounts for each time zone are integrated, the power consumption amount in the rapid heating mode may be calculated based on the total number of times of use of the toilet for the predetermined period, and one of the learning mode and the rapid heating mode, in which the calculated power consumption amount is smaller, may be selected. Alternatively, the electric power rate may be calculated instead of the electric power consumption amount, and one of the learning mode and the rapid heating mode in which the calculated electric power rate is smaller may be selected. When the electricity rate changes in time slots, the electricity rate may be calculated by multiplying the unit price of the electricity rate in each time slot by the amount of electricity consumed in each time slot. The unit price of the electricity rate for each time slot may be manually input by the user or may be acquired from an external device through communication.
As the control mode of the toilet seat heating control, the first embodiment has a normal mode and a quick heating mode, and the second embodiment has a learning mode and a quick heating mode. However, it is also possible to have three modes of a normal mode, a learning mode, and a rapid heating mode, and select and execute these modes. In addition, it is also possible to have only the rapid heating mode. In the latter case, as shown in fig. 14, when the user is not detected by the entry detection sensor 24, the standby temperature Tw lower than the set temperature Ts is set to the target temperature T, and the toilet seat heater 20 is controlled based on the set target temperature T, and when the user is detected by the entry detection sensor 24, the set temperature Ts is set to the target temperature T, and the toilet seat heater 20 is controlled based on the set target temperature T. The standby temperature Tw is set to be higher when the frequency of use F is high than when the frequency of use F is low, and set to be lower when the outside air temperature Ta is high than when the outside air temperature Ta is low. According to this modification, comfort and power saving performance can be well balanced.
