  The electric heater 15 has a function of causing heat exchange between the washing water and the heat source using tap water passing through the washing water as a washing water. There are no particular restrictions. The incoming water temperature sensor 13 and the outgoing water temperature sensor 14 are composed of, for example, a thermistor and are provided at the inlet and outlet of the electric heater 15, respectively. A flow rate sensor 16 is provided upstream of the water inlet of the electric heater 15 (not shown).

  The power supply unit 17 receives commercial power and supplies AC or DC power to the electric heater 15. In the power supply path from the power supply unit 17 to the electric heater 15, a switch element 18 that connects and disconnects the power supply is provided. The type of the switch element 18 is not particularly limited, and can be constituted by, for example, a thyristor, a bipolar transistor, a field effect transistor, or the like.

  The control unit 19 includes an arithmetic element such as a microcomputer, an output circuit that controls the switch element 18, and the like, and performs energization control of the electric heater 15 based on feedforward control or the like with respect to the incoming water temperature.

  The washing water is preloaded by a pump or the like (not shown), and the flow rate thereof is variably controlled by an electromagnetic valve or the like (not shown) arranged on the upstream side of the flow rate sensor 16.

  A water outlet 20 made of a drain pipe or the like made of rubber or silicon is connected to the downstream side of the electric heater 15. The warm water cleaning toilet device cleans the user's local area by heating and sending the cleaning water from the electric heater 15 and ejecting it from the outlet 20. The water channel switching valve 21 provided in the water discharge channel 20 is constituted by, for example, an electromagnetic valve, receives a control signal from the control unit 19, and discharges the cleaning water as a terminal end of the water discharge channel 20. 23 is selected.

  FIG. 2 shows a specific configuration of the hot water cleaning toilet device. The hot-water toilet device is a western type, and is composed of a toilet body 1 in which a bowl portion 1 a for receiving a stool is formed, a toilet seat 2 that can be opened and closed with respect to the toilet body 1, and a lid 3. The operation unit 12 is a remote control type that is separate from the device and is installed on the wall surface, and performs information communication with the hot water flush toilet device in a wired or wireless manner.

  The toilet body 1 includes a bowl portion 1a formed of resin, porcelain, and the like, and a resin structure portion 1b that supports the bowl portion 1a. Inside the resin structure portion 1b, the washing water heating unit and the drainage mechanism ( A water injection mechanism (not shown) and the like are accommodated. A room temperature detector 11 and the like are provided on the side surface of the toilet body 1, and a power plug 1c connected to a commercial power outlet and a pressure hose 1d connected to the stop cock 4 are led out from the back. ing.

  A drain port 1e is formed at the bottom of the bowl portion 1a, and the drain port 1e is connected to a drainage mechanism (not shown) for controlling drainage of sewage. In addition, a plurality of water injection ports (not shown) are formed along the edge of the upper surface opening of the bowl portion 1a, and these water injection ports are connected to a water injection mechanism (not shown) for controlling water injection of tap water. Yes. Further, on the rear side of the upper surface opening of the bowl portion 1a, a nozzle 22 for jetting cleaning water for cleaning the local portion and a hot air outlet 1f for blowing out hot air for drying the cleaned local portion are provided. ing.

  The nozzle 22 is a cylindrical member having an ejection hole formed on the top surface of the tip, and its base is connected to a displacement mechanism (not shown). It protrudes to the inside of 1a.

  Although it has been described above that either the nozzle 22 or the drainage hole 23 is selected as the end of the outlet channel 20 by the waterway switching valve 21, the drainage hole 23 may be formed on the lower surface of the nozzle 22. And may be provided independently (not shown). Or you may make it switch the function of the nozzle 22 to the ejection or drainage of washing water by a position. In other words, when the nozzle 22 is in the forward position, the wash water ejected from the nozzle 22 goes directly to the local area, but when the nozzle 22 is in the retracted position, the wash water ejected from the nozzle 22 It is received by the wall surface of the nozzle storage portion 1g and drained into the bowl portion 1a through a predetermined path. At this time, the same function as the water channel switching valve 21 is executed by the displacement mechanism of the nozzle 22.

  The toilet seat 2 is made of a resin or the like and is formed in a substantially elliptical plate shape with an opening at the center. The rear portion of the toilet seat 2 is fixed to the toilet body 1 so as to be openable and closable, and a heat source (not shown) for heat insulation is embedded. ing. Furthermore, a human body detection unit 24 made of a piezoelectric element or the like may be embedded in the toilet seat unit 2 to keep the toilet seat unit 2 warm while detecting a human body.

  The lid portion 3 is made of resin or the like, has a shape corresponding to the toilet seat portion 2, and its rear portion is fixed to the toilet body 1 so as to be openable and closable. The toilet seat 2 and the lid 3 may be opened and closed manually or electrically.

  Here, the usage form of the hot water flush toilet device will be briefly described. Usually, tap water is stored in the bowl portion 1a, and stool is used in this state. Then, when a cleaning command is given by the operation unit 12 after the stool, the cleaning water heated and sent out by the operation of the cleaning water heating unit is ejected from the nozzle 22 toward the local part. Further, when a warm air command is given by the operation unit 12, the warm air is sent from the warm air outlet 1f toward the local area to dry the local area. Thereafter, when a drainage command is issued at the operation unit 12, the drainage mechanism is activated and the sewage accumulated in the bowl portion 1a is discharged from the drainage port 1e, and the water injection mechanism is also activated to inject tap water into the bowl portion 1a. To be washed. The tap water is continuously poured for a while after the discharge of the sewage is completed, whereby the tap water is stored again in the bowl portion 1a.

  Conventionally, in the hot water toilet apparatus as described above, the residual water in the outlet channel 20 is heated before the washing water is jetted out so that the cold washing water is jetted out immediately after the jetting starts and the user does not feel uncomfortable. What has been provided with a so-called pre-cleaning function that drains by flushing with washed water has been proposed. However, particularly when the room temperature is low, the water outlet 20 is not sufficiently heated by itself, and there is a problem that the wash water heated and sent from the electric heater 15 is cooled while passing through the water outlet 20.

  The present invention is intended to solve such problems. That is, the reason that the washing water becomes cold when the room temperature is low is mainly because the drainage channel 20 remains cold. Therefore, the execution time of the pre-cleaning function required to warm the drainage channel 20 with reference to the room temperature. The purpose is to execute the pre-cleaning function by adjusting (hereinafter referred to as pre-cleaning time).

  The warm water cleaning toilet apparatus includes a room temperature detection unit 11 that detects room temperature as a component for that purpose, and the pre-cleaning time is set based on the room temperature detected by the room temperature detection unit. Basically, the pre-cleaning time is increased if the room temperature is low, but if the room temperature is above a certain level, the pre-cleaning time is constant, and if the room temperature is lower than that, the pre-cleaning time is longer as the room temperature is lower. You may make it. In short, it is sufficient that a sufficient cleaning time can be set when the room temperature is low.

  Hereinafter, an example in which the pre-cleaning time is set to be longer as the room temperature is lower will be described as an example.

  The graph of FIG. 3 shows the change over time in the temperature of the water discharge channel (including the amount to be drained and the amount to be ejected) after the cleaning instruction is received and the electric heater starts to heat and send the cleaning water. It shows about each in the case of 15 degreeC and 5 degreeC.

  Here, the electric heater is an instantaneous type, and the temperature of the wash water delivered therefrom reaches the hot water temperature set value in a very short time from the start of operation of the electric heater, regardless of the incoming water temperature or room temperature. The hot water set value is 40 ° C. as an example, and in the figure, the temperature change of the sent wash water is indicated by a dotted line.

  The outlet channel is at room temperature at the time of the cleaning command, but is heated by heat exchange with the heated cleaning water, and finally reaches the same temperature as the cleaning water. The gradient at which the water outlet is heated is determined by the heat capacity and heat conductivity of the water outlet.

  As a basic idea, if the temperature and flow rate of the wash water are known, the temperature change of the outlet channel heated by heat exchange with the cooling water can be obtained with little error from the initial temperature and elapsed time of the outlet channel. it can. Therefore, in the present invention, the pre-cleaning time for each room temperature is defined as the time required for the temperature of the outlet channel to reach the target temperature, starting from the time when the cleaning water delivered from the electric heater reaches the predetermined temperature. To do. Here, as an example, the predetermined temperature of the wash water is 35 ° C., and the target temperature of the water discharge channel is 30 ° C., but it is not limited to this. If the pre-cleaning time has elapsed, the nozzle is automatically switched and selected as the end of the water discharge channel, and local cleaning is started.

  In the figure, the pre-cleaning time for the room temperature of 5 ° C. is indicated by t5, the pre-cleaning time for the room temperature of 15 ° C. is indicated by t15, and the interval between the pre-cleaning for the room temperature of 25 ° C. is indicated by t25. The pre-cleaning times t5, t15, and t25 are defined as the elapsed time from the time when the temperature of the cleaning water delivered by the electric heater exceeds 35 ° C, and the value at which the temperature of the outlet channel is 30 ° C or higher is specified in advance. Has been. Of course, the lower the room temperature, the longer it takes for the temperature of the drainage channel to rise, so the magnitude relationship is t5> t15> t25.

  As specific control, a combination of the room temperature and the pre-cleaning time may be prepared in advance in the control unit as a matrix. For example, t5 is selected as the pre-cleaning time if the room temperature is less than 10 ° C, t15 is selected as the pre-cleaning time if the room temperature is 10 ° C or higher and less than 20 ° C, and the pre-cleaning time is selected if the room temperature is 20 ° C or higher. T25 may be selected. The number of combinations of the room temperature and the pre-cleaning time is not particularly limited, and if the number of combinations is increased, the more precise control becomes possible. Alternatively, a function of room temperature and pre-cleaning time may be defined, and the pre-cleaning time may be calculated from the function.

  During execution of the pre-cleaning function, the drain hole is selected as the end of the water discharge channel, and when the pre-cleaning time has elapsed, the end of the water discharge channel is switched to the nozzle. Subsequent ejection of cleaning water from the nozzle continues while receiving a cleaning command.

  The flowchart of FIG. 4 shows an example of a basic processing procedure of the pre-cleaning function in the warm water cleaning toilet device.

  Step 100 is a process of receiving a cleaning command. This process is repeated until a cleaning command is received. Step 101 is a process of selecting a drain hole as the end of the water discharge channel. Step 102 is processing for starting the heating and sending of the washing water.

  Step 103 is a process for determining the temperature of the cleaning water. This process is repeated until the temperature of the washing water reaches 35 ° C. Step 104 is a process for detecting the room temperature. If the room temperature is less than 10 ° C., t5 is selected as the pre-cleaning time in step 105. On the other hand, if the room temperature is 10 ° C. or higher and lower than 20 ° C., t15 is selected as the pre-cleaning time in step 106, and if the room temperature is 20 ° C. or higher, t25 is selected as the pre-cleaning time in step 107.

  Step 108 is processing for starting the time for pre-cleaning time, and step 109 is processing for determining whether or not the pre-cleaning time has elapsed. This step is repeated until the cleaning time elapses. During that period, the remaining water in the outlet channel continues to be drained from the drain hole 23 by the cleaning water heated and sent out. After all the residual water is drained, the cleaning water is drained from the drain hole. This warms the waterway.

  Step 110 is a process of selecting a nozzle as the end of the water discharge channel because the pre-cleaning time has elapsed. By this processing, the pre-cleaning function ends, cleaning water starts to be ejected from the nozzle, and local cleaning is started.

  In the present invention, the pre-cleaning function is executed by setting the execution time of the pre-cleaning function to be longer as the room temperature is lower before cleaning the local area. Waterways are sufficiently warmed. As a result, there is no risk of cold water being ejected toward the local area.

  As described above, in the present embodiment, before the local portion is cleaned, the pre-cleaning function is executed by setting the execution time of the pre-cleaning function to be longer as the room temperature is lower, so even if the room temperature is low The drainage channel is sufficiently warmed by pre-cleaning. As a result, there is no risk of cold water being ejected toward the local area.

  Next, a modification of the embodiment will be described. That is, as a modification, when the warm water cleaning toilet device detects sitting on the toilet seat, it automatically executes the pre-cleaning function without receiving a cleaning command, and then restarts the pre-cleaning function when receiving the cleaning command. It is good also as a structure which wash | cleans a local part after performing.

  That is, the warm water cleaning toilet device automatically executes the pre-cleaning function when the human body detection unit 24 detects the human body. The pre-cleaning time at this time may be selected based on the room temperature detected by the room temperature detector 11. Further, the hot water cleaning toilet device also performs a pre-cleaning function when receiving a cleaning command. The pre-cleaning period at this time may be selected based on the room temperature detected by the room temperature detection unit 11 and the elapsed time since the human body detection unit 24 detected the human body. In this case, the pre-cleaning time may be prepared in advance in the control unit 19 as a matrix of room temperature and elapsed time.

  FIG. 5 shows a basic configuration of a washing water heating unit related to the present invention in such a warm water washing toilet apparatus. 1 is different from that shown in FIG. 1 in that a human body detection unit 24 that detects the seating of a person is provided. Since the other components are basically the same as those in FIG. 1, the same reference numerals are assigned and description thereof is omitted.

  The configuration of the human body detection unit 24 is not particularly limited. For example, a piezoelectric element or the like embedded in the toilet seat 2 may be configured to detect the user's seating (see FIG. 2), or an infrared sensor or the like provided at an appropriate position may be configured to detect the user's entry or seating. Good.

  This modification is intended to pre-warm the water outlet before receiving a cleaning command by executing the pre-cleaning function once when a human body is detected. Thus, the pre-cleaning time after receiving the cleaning command can be shortened and the local cleaning can be started earlier.

  The graph of FIG. 6 shows the temperature change of the outlet when the washing command is given 2 minutes, 4 minutes and 6 minutes after the detection of the human body, respectively, at room temperature 25 ° C, 15 ° C and 5 ° C. Is shown. The hot water temperature set value is 40 ° C. as an example, and in the figure, the temperature change of the wash water (the outlet of the electric heater) is indicated by a dotted line. Moreover, the temperature change of the water discharge channel when time passes without a washing command being given is indicated by a solid line, and the temperature change of the water discharge channel when a cleaning command is received is indicated by a dotted line, a broken line or a chain line.

  A human body is detected at 0 min, heating and sending out of washing water starts for the pre-cleaning function, and the temperature of the drainage channel starts to rise from room temperature. The pre-cleaning time at this time is t5-2 if the room temperature is less than 10 ° C, t5-2 if the room temperature is 10 ° C to less than 20 ° C, and t5-25 if the room temperature is 20 ° C or more. select. The pre-cleaning times t5-2, t15-2, and t25-2 are defined as the elapsed time from the time when the temperature of the cleaning water delivered by the electric heater exceeds 35 ° C., and at each room temperature, 2 min from human body detection. In this case, a value at which the temperature of the water discharge channel is 30 ° C. or higher is specified in advance.

  If such a value is selected as the pre-cleaning time for human body detection, when a cleaning command is received within 2 minutes from human body detection, the temperature of the drainage channel should be 30 ° C or higher, so the pre-cleaning function is executed. There is no problem even if the local cleaning is started immediately without doing so.

  In the figure, when a cleaning command is received for 2 minutes, the local cleaning is started without executing the pre-cleaning function. If a cleaning instruction is received while the pre-cleaning function is being executed by human body detection, local cleaning may be started after the pre-cleaning function is completed.

  On the other hand, when the pre-cleaning function is executed by the human body detection and the time elapses without receiving the cleaning command, the temperature of the outlet channel gradually decreases as shown by the solid line.

  If the washing command is received for 4 minutes, the temperature of the water discharge channel will rise as shown by the alternate long and short dash line in the figure. Here, for each of room temperature 5 ° C., 15 ° C., and 25 ° C., t5-4, t15-4, and t25-4 are respectively given during the pre-cleaning necessary for warming the drainage channel to 30 ° C. Therefore, when a cleaning command is received between 2 min and 4 min, t5-4 is selected as the cleaning time if the room temperature is less than 10 ° C, and t15-4 is selected if the room temperature is between 10 ° C and less than 20 ° C. If the room temperature is 20 ° C. or higher, t15-4 may be selected. If it does so, the temperature of a water outlet can be about 30 degree | times or more after execution of a pre-cleaning function.

  Here, it is assumed that the temperature of the drainage channel is lowered to room temperature in 6 minutes. If the cleaning command is received for 6 minutes, the temperature of the water outlet will rise as shown by the two-dot chain line in the figure. For each of room temperature 25 ° C., 15 ° C., and 5 ° C., the pre-cleaning intervals required to warm the water outlet to 30 ° C. are t5-6, t15-6, and t25-6, respectively. At this time, the temperature of the drainage channel is room temperature and does not drop any further. Therefore, when a cleaning command is received after 4 minutes, the cleaning time is t5-6 if the room temperature is less than 10 ° C, and t15-6 is selected if the room temperature is 10 ° C or more and less than 20 ° C. If it is 20 ° C. or higher, t25-6 may be selected. If it does so, the temperature of a water outlet can be about 30 degree | times or more after execution of a pre-cleaning function.

As can be seen from the figure, when the room temperature is less than 10 ° C., the pre-cleaning time has the following magnitude relationship with respect to the elapsed time from human body detection.
Pre-cleaning time when receiving a cleaning command from human body detection by 2 min (0) <Pre-cleaning time when receiving a cleaning command from 2 min to 4 min (t5-4) <When receiving a cleaning command after 4 min The pre-cleaning time (t5-6).

  The same applies when the room temperature is 10 ° C. or higher and lower than 20 ° C. or when the room temperature is 20 ° C. or higher. That is, the shorter the elapsed time from human body detection (the execution of the pre-cleaning function thereby), the shorter the pre-cleaning time when receiving a cleaning command thereafter. Thereby, the user's frustration due to the fact that the local cleaning is not started immediately can be reduced.

  In the example shown in FIG. 6, the elapsed time from human body detection is divided into three parts of less than 2 minutes, less than 2 minutes, less than 4 minutes, and more than 4 minutes. Pre-cleaning time can be shortened more precisely and without waste.

  As a further modification, the basic configuration shown in FIG. 1 may be used, and the control method by the control unit 19 may be varied. Specifically, the warm water cleaning toilet device periodically performs pre-cleaning until receiving a cleaning command. The pre-cleaning time at this time may be selected based on the room temperature detected by the room temperature detector 11. Furthermore, the warm water cleaning toilet device also performs a pre-cleaning function when receiving a cleaning command. The pre-cleaning interval at this time may be selected based on the room temperature detected by the room temperature detector 11 and the elapsed time from the last execution of the pre-cleaning function. The first time of the pre-cleaning function that is periodically executed may be executed at the power-on timing, or may be executed at the timing when the human body detection unit 24 is provided and the human body is detected. In any case, if no cleaning command is received, the pre-cleaning function is automatically executed every predetermined time.

  As an example of the operation mode, for example, in FIG. 6, the pre-cleaning function is executed at 0 min by human body detection, and thereafter, the pre-cleaning function is executed every 4 min if no cleaning command is received.

  With such a modification, the pre-cleaning time when receiving the cleaning command can be shortened on average regardless of the length of use time. This effect is particularly prominent in an environment where the temperature of the water channel tends to decrease, such as in a cold region.
