First, a schematic basic configuration of a flush toilet device 1 with a hand basin (hereinafter abbreviated as flush toilet device 1) according to the present embodiment will be described.

The flush toilet device 1 is a toilet device comprising a control unit 30 for controlling water supply to the toilet bowl 11 and the water supply to the hand washing bowl 16, and a cleaning instruction means 31 for instructing the control unit 30 to supply water to the toilet bowl 11. be. The washing instruction means 31 is configured to select and determine a washing mode from a plurality of washing patterns including at least a large amount of water supply and a small amount of water supply. The control unit 30 is configured to control the water supply by varying the water supply mode to the hand washing bowl 10 according to the cleaning mode determined by the cleaning instruction means 31 .

Next, details of the flush toilet device 1 will be described. FIG. 1 is a diagram showing the configuration of the flush toilet device 1. As shown in FIG. It should be noted that the toilet bowl 11 of this embodiment has two patterns for washing the toilet bowl 11, ie, a large amount of water supply and a small amount of water supply.

The flush toilet device 1 comprises a toilet body 10 having a toilet bowl 11 and a hand basin 15 having a hand washing bowl 16. - 特許庁A wash water pipe 22 having a wash water control valve 21 is connected to the toilet body 10, a water discharge pipe 24 having a hand wash control valve 23 is connected to the hand basin 15, and water is supplied to both pipes through the water supply pipe 20. It is configured to be possible. A drain pipe 25 is connected between the hand basin 15 and the toilet body 10, and the water flowing in the hand washing bowl 16 is discharged to the toilet body 10 side.

Further, the toilet seat 12 of the toilet body 10 is equipped with a weight detection sensor 37 and a seat sensor 36 . The weight detection sensor 37 constitutes a weight detection section that detects the weight of a person seated on the toilet seat 12 . The seating sensor 36 is configured to detect seating/leaving with respect to the toilet seat 12 . Instead of the seat sensor 36, the weight detection sensor 37 determines that the user is seated when the detected value changes from zero to a predetermined value or more, and determines when the detected value changes from a predetermined value or more to zero. It may be determined that the user leaves the seat.

The toilet body 10 incorporates a control section 30 configured by a CPU, a program, and the like. The supply/stop of flush water to the toilet bowl bowl 11 is performed by opening/closing the flush water control valve 21, and the operation is controlled by the control section 30 as described above. Water supply (discharging) to/from the hand wash bowl 16 is controlled by opening/closing the hand wash control valve 23 , which is also controlled by the controller 30 .

The flush toilet device 1 also includes an operation unit 32 as means for giving instructions to the control unit 30 . The operation unit 32 includes an operation switch (not shown) provided on the toilet body 10 and a remote controller 32A (see FIG. 2) attached to the wall surface. The operation unit 32 is provided with a washing operation unit 33 for instructing a large amount of water supply and a small amount of water supply to the toilet bowl 11 and a hand washing water supply operation unit 34 .

An instruction to control the supply of flush water to the toilet bowl 11 is given to the control unit 30 by the flush instruction means 31 . Examples of the washing instruction means 31 include the toilet body 10 and the washing operation section 33 of the operation section 32 . Alternatively, the washing instruction means 31 may be based on the detection of the seating sensor 36 leaving the seat. The cleaning instruction in this case is a cleaning instruction for supplying a large amount of water, but may be an instruction for supplying a small amount of water.

In addition, the control unit 30 is instructed to control water discharge to the hand wash bowl 16 by the hand wash water supply operation unit 34 of the operation unit 32. may be substituted with different operations. For example, a long press or a continuous operation may be used.

Furthermore, in the flush toilet device 1 , the water discharge instruction to the hand wash bowl 16 is interlocked with the supply of flush water to the toilet bowl 11 . This interlocking operation will be described with reference to FIGS. 2(a) and 2(b) and flowcharts of control operations by the control unit 30 (S101 to S105 in FIG. 3 and S201 to S205 in FIG. 4).

In this embodiment, when a large amount of water supply is selected as flush water supply to the toilet bowl 11, the water supply is controlled so that the amount of water supplied to the hand washing bowl 16 is increased more than in the case of a small amount of water supply. ing. That is, when the amount of flushing water supplied to the toilet bowl 11 is large, the amount of flushing water supplied to the hand washing bowl 16 is increased (see FIG. 2(a)), and when the amount of flushing water supplied to the toilet bowl 11 is small. is to reduce the amount of water supplied to the hand-washing bowl 16 (see FIG. 2(a)).

This interlocking operation is started based on the instruction from the washing instruction means 31 to the toilet bowl bowl 11 as described above. This cleaning instruction is issued by operating the cleaning operation unit 33 (FIG. 3) or by detecting the seating sensor 36 leaving the seat (FIG. 4), as described above.

Further, in the present embodiment, when the washing instruction is given by the washing instruction means 31, the control unit 30 compares the weight detected by the weight detection sensor 37 with a predetermined threshold value, and determines based on the determination result. It is configured to determine the mode of water supply to the hand washing bowl 16 .

Hereinafter, the cleaning instruction by operating the cleaning operation unit 33 and the cleaning instruction by the seat separation detection by the seating sensor 36 will be described separately.

When a washing instruction is given by the washing operation unit 33, as shown in FIG. 3, it is determined whether or not the weight measured by the weight detection sensor 37 is equal to or less than a predetermined threshold value (S101). This predetermined value is a weight value for distinguishing between a child and an adult. If the seat is being seated (by reading the seat sensor 36), the detection value of the weight detection sensor 37 at that timing can be read. and use it as the weight value of the most recent user.

When the weight exceeds a predetermined value, that is, when the child is an adult, the specified large or small amount of cleansing water is supplied to the toilet bowl 11, and the washing water to the toilet bowl 11 is supplied to the hand washing bowl 16. Water is supplied in a water supply mode corresponding to the washing mode (large or small) (S101 to S103). In short, when a large amount of flushing water is supplied to the toilet bowl 11, a large amount of water is also discharged to the hand-washing bowl 16. Spits out a small amount of water. For example, if the ratio of flushing water to the toilet bowl 11 is 4:3, the ratio of spouting water to the hand washing bowl 16 may also be 4:3.

If the weight is less than a predetermined value, that is, if the child is determined to be a child, the indicated large or small amount of cleansing water is supplied to the toilet bowl 11, and water is supplied to the hand washing bowl 16 in a water supply mode for children. (S101, S104, S105). The water supply mode for children is assumed to be, for example, spouting the same amount of water as that for adults, but with a smaller unit time spouting amount. Therefore, water spouting time is longer than that for adults. Also, the water discharge time may be varied according to the size of flush water in the toilet bowl 16 .

When a cleaning instruction is given by detecting the seating sensor 36 leaving the seat, as shown in FIG. 4, it is determined whether or not the weight measured by the weight detection sensor 37 is equal to or less than a predetermined threshold value (S201). This predetermined value is a weight value for distinguishing between a child and an adult. As the weight value in this case, the most recent detected value of the stored weight detection sensor 37 may be used.

When the weight exceeds a predetermined value, that is, when the child is an adult, the specified large or small amount of cleansing water is supplied to the toilet bowl 11, and the washing water to the toilet bowl 11 is supplied to the hand washing bowl 16. Water is supplied in a water supply mode corresponding to the washing mode (S201 to S203). In short, since a large amount of flushing water is supplied to the toilet bowl 11 in this case, a large amount of water may be discharged to the hand washing bowl 16 as well. Instead of spouting a large amount of water, it may be spouted for a longer time than when a small amount of cleansing water is directed to the toilet bowl 11 while reducing the amount of water spouted per unit time. Further, the start time of water spouting may be delayed from when a small amount of cleansing water is directed to the toilet bowl 11 so that water is spouted later.

If the weight is equal to or less than a predetermined value, that is, if the child is a child, the specified large or small amount of cleansing water is supplied to the toilet bowl 11, and water is supplied to the hand washing bowl 16 in a water supply mode for children (S201). , S204, S205). As in the case of FIG. 3, it is assumed that the water supply mode for children is, for example, spouting the same amount of water as that for adults, but with a smaller unit time spouting amount.

As described above, the mode of water supply to the hand-washing bowl 16 is varied according to the mode of cleaning the toilet bowl 11, so that a large toilet bowl can be washed with a large amount of water, and a small toilet bowl can be washed with a large amount of water. A small amount of water is sufficient. In short, hand washing can be performed with an appropriate water supply mode according to the washing mode of the toilet bowl 11 . If the amount of water is large when the size is large, it is possible to wash hands with soap, and if the amount of water is small when the size is small, water can be saved.

Although it is desirable that the water supply mode is the same amount of water spouted per unit time and the duration of water spouting is different, the water supply mode is not limited to this, and the amount of water spouted per unit time may be made different.

In addition, since it is possible to distinguish whether it is a child or an adult, and the water supply mode is set accordingly, it is possible for children to wash their hands for a long time or a large amount of hands, so that children can wash their hands carefully. Incidentally, when it is determined that the person is a child, the mode of water supply to the hand washing bowl 16 may be determined regardless of the mode of cleaning the toilet bowl 11 .

In the embodiment described above, there are two types of washing patterns for the toilet bowl bowl 11, that is, a large amount of water supply and a small amount of water supply. good too. In that case, the water supply to the hand-washing bowl 16 may also be in a water supply mode that matches the pattern. Further, in the above embodiment, the water supply mode is determined according to the weight measured by the weight detection sensor 37, but the water supply mode is determined by the washing instruction means 31 without using the weight measured by the weight detection sensor 37. The mode of water supply to the hand-washing bowl 16 may be determined only in response to the cleaning mode.
