Description

Aspects of the present invention generally relate to toilet devices and toilet systems.

A toilet device that determines clogging of a toilet bowl by detecting the water level of the toilet bowl is known (for example, Patent Document 1). As a means for detecting the water level of the toilet bowl, for example, there is a method of confirming the water level of the bowl of the toilet bowl using a radio wave sensor such as a microwave sensor. However, if filth continues to adhere to the bowl detected by the radio wave sensor, the radio wave sensor mistakenly determines that the filth is water, even though it is not actually clogged. If the toilet bowl is clogged, it may cause a false positive.

Japanese Patent No. 5605765

The present invention has been made based on the recognition of such a problem, and an object of the present invention is to provide a toilet device and a toilet system capable of more accurately detecting clogging of a toilet bowl.

The present invention includes a detection unit that detects whether or not the water level in the bowl portion of the toilet bowl is lower than the full water level and higher than the sealed water level, and based on the detection result of the detection unit, the toilet bowl. A determination unit for determining a clogged state is provided, and the detection unit is a portion different from the bowl portion, and the water level of the water level changing portion that changes the water level in conjunction with the water level in the bowl portion of the toilet bowl. The toilet is characterized in that it detects whether or not the water level in the bowl portion is lower than the full water level and higher than the sealed water level through the water level of the water level changing portion. It is a device.

According to this toilet device, the detection unit detects the water level of the water level change part that changes the water level in conjunction with the water level in the bowl part of the toilet bowl, which is a part different from the bowl part, and the water level of the water level change part. By detecting whether or not the water level in the bowl portion is lower than the full water level and higher than the sealing level, even if filth containing water adheres to the bowl portion, the filth Is erroneously detected as water, and it is possible to prevent erroneous determination that clogging has occurred. Therefore, it is possible to provide a toilet device that can more accurately detect clogging of the toilet bowl.

According to the aspect of the present invention, it is possible to provide a toilet device and a toilet system that can more accurately detect a clogging of a toilet bowl.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each drawing, similar components are designated by the same reference numerals and detailed description thereof will be omitted as appropriate.
FIG. 1 is an explanatory diagram schematically showing a toilet system according to an embodiment.
As shown in FIG. 1, the toilet system 2 includes a toilet device 10, a toilet bowl 12, a washing water supply unit 14, a control unit 16, and an operation unit 18.

The toilet bowl 12 has a concave bowl portion 12a that is recessed downward. A toilet seat (not shown) is provided on the toilet bowl 12. The toilet bowl 12 receives excrement such as urine and stool excreted from the user seated on the toilet seat at the bowl portion 12a. The toilet bowl 12 is, more specifically, a Western-style sitting toilet bowl.

The wash water supply unit 14 supplies wash water to the toilet bowl 12. The wash water supply unit 14 has, for example, a pipe 14a and an on-off valve 14b. The pipe 14a connects the toilet bowl 12 and a water supply source such as a water supply or a water storage tank. The on-off valve 14b is provided on the path of the pipe 14a. The on-off valve 14b has, for example, a drive unit such as a solenoid or a motor, and a valve mechanism that opens and closes according to the drive of the drive unit. The on-off valve 14b is, for example, a solenoid valve. The wash water supply unit 14 supplies the wash water from the water supply source to the toilet bowl 12 by opening the on-off valve 14b, and stops the supply of wash water to the toilet bowl 12 by closing the on-off valve 14b.

The configuration of the washing water supply unit 14 is not limited to the above. The wash water supply unit 14 may have, for example, a configuration including a water storage tank (for example, a low tank) and a motor for opening and closing the stool of the water storage tank. The structure of the wash water supply unit 14 may be any structure capable of supplying wash water to the toilet bowl 12.

The control unit 16 communicates with the wash water supply unit 14 and the operation unit 18. The communication between the wash water supply unit 14 and the control unit 16 and the communication between the control unit 16 and the operation unit 18 may be wired or wireless.

The operation unit 18 is a toilet bowl cleaning button, a remote controller, or the like. The operation unit 18 receives the operation of the user, and in response to the input of the operation, inputs the toilet bowl cleaning signal instructing the cleaning of the toilet bowl 12 to the control unit 16.

The control unit 16 controls the supply of wash water to the toilet bowl 12 by the wash water supply unit 14 in response to the input of the toilet bowl wash signal from the operation unit 18. The control unit 16 opens the on-off valve 14b in response to an input to the toilet bowl cleaning signal from the operation unit 18, and closes the on-off valve 14b in response to the passage of a predetermined time or the supply of a predetermined flow rate. As a result, according to the operation of the operation unit 18 by the user, a predetermined flow rate of washing water is supplied into the bowl portion 12a of the toilet bowl 12, and the toilet bowl 12 is washed. As a result, the filth and the like excreted in the bowl portion 12a can be flushed to an external drain pipe or the like.

The volume of the bowl portion 12a is larger than the amount of wash water supplied to the bowl portion 12a by the wash water supply unit 14 and the control unit 16 in one toilet bowl wash. As a result, even if the toilet bowl is washed once with the bowl portion 12a clogged, it is possible to prevent the washing water from overflowing from the opening at the upper edge of the bowl portion 12a.

The toilet device 10 detects clogging of the toilet bowl 12. The toilet device 10 has a detection unit 20 and a determination unit 22.

The detection unit 20 detects whether or not the water level in the bowl portion 12a of the toilet bowl 12 is lower than the full water level WL1 and higher than the sealed water level WL2. The full water level WL1 is a position where the washing water overflows from the inside of the bowl portion 12a. The full water level WL1 is, for example, the position of the upper surface 12b of the toilet bowl 12. The water sealing level WL2 is the position of the washing water (sealing water) that collects in the bowl portion 12a after the washing of the toilet bowl 12 is completed.

For the detection unit 20, for example, a radio wave sensor, a capacitance sensor, or the like is used. The radio wave sensor emits radio waves and detects the water level based on the change in the intensity of the reflected wave with and without water. The capacitance sensor detects the water level based on the change in capacitance with the presence or absence of water. However, the detection unit 20 is not limited to the radio wave sensor and the capacitance sensor, and may be any sensor that can appropriately detect the water level.

The determination unit 22 determines the clogged state of the toilet bowl 12 based on the detection result of the detection unit 20. When the detection unit 20 detects that the water level in the bowl portion 12a of the toilet bowl 12 is lower than the full water level WL1 and not higher than the sealed water level WL2, the determination unit 22 is clogged with the toilet bowl 12. Judge that there is no. Then, when the detection unit 20 detects that the water level in the bowl portion 12a of the toilet bowl 12 is lower than the full water level WL1 and higher than the sealed water level WL2, the determination unit 22 causes the toilet bowl 12 to perform. Judge that it is clogged.

The determination unit 22 communicates with the control unit 16. The communication between the determination unit 22 and the control unit 16 may be wired or wireless. The determination unit 22 inputs a clogging detection signal to the control unit 16 in response to the determination that the toilet bowl 12 is clogged.

When the control unit 16 receives the clogging detection signal, the control unit 16 disables the operation of the wash water supply unit 14. That is, when the control unit 16 receives the clogging detection signal, the toilet bowl 12 is not cleaned even when the toilet bowl cleaning signal is input from the operation unit 18. As a result, it is possible to supply the washing water to the bowl portion 12a in a state where the toilet bowl 12 is clogged, and prevent the washing water from overflowing from the bowl portion 12a.

The determination unit 22 makes the above determination based on, for example, the detection result of the detection unit 20 after a lapse of a predetermined time from the end of the toilet bowl cleaning. The predetermined time is, for example, about 4 seconds to 12 seconds. As a result, it is possible to prevent the water level during cleaning of the toilet bowl from being detected. Further, it is possible to prevent the toilet bowl portion 12a from overflowing due to continuous toilet bowl cleaning in a state where the toilet bowl 12 is clogged by making the predetermined time too long.

FIG. 2 is a cross-sectional view schematically showing a part of the toilet bowl according to the embodiment.
As shown in FIGS. 1 and 2, the toilet bowl 12 has a bowl portion 12a and is a portion different from the bowl portion 12a, and the water level changes in conjunction with the water level in the bowl portion 12a. It also has a portion WVP. The water level change portion WVP is, for example, a wash water supply channel 30 for supplying wash water into the bowl portion 12a.

The toilet bowl 12 has spouts 32 and 34, a common water supply channel 36, and a wash water supply channel 38. The common water supply channel 36 is connected to the pipe 14a of the washing water supply unit 14 and receives the washing water supplied from the pipe 14a. The common water supply channel 36 is provided, for example, on the rear side of the bowl portion 12a. The pipe 14a is connected to the toilet bowl 12 and the common water supply channel 36 on the back side of the toilet bowl 12, for example, and supplies wash water to the common water supply channel 36.

The spout 32 is provided above the bowl portion 12a. The spout 32 is provided at least above the sealing level WL2. The wash water supply channel 38 connects the water discharge port 32 and the common water supply channel 36, and supplies the wash water from the common water supply channel 36 to the water discharge port 32. The water discharge port 32 cleans the bowl surface of the bowl portion 12a by discharging the wash water supplied from the wash water supply channel 38 to the bowl portion 12a. The spout 32 discharges wash water substantially horizontally toward the bowl portion 12a, for example, and forms a swirling flow that swirls along the bowl surface. As a result, the bowl surface can be cleaned more reliably. The spout 32 may be referred to as, for example, a rim spout.

The spout 34 is provided at the bottom of the bowl portion 12a. The spout 34 is provided below, for example, the sealing level WL2. The wash water supply channel 30 connects the water discharge port 34 and the common water supply channel 36, and supplies the wash water from the common water supply channel 36 to the water discharge port 34. The water discharge port 34 discharges the wash water supplied from the wash water supply channel 30 toward the water sealing portion 12c of the toilet bowl 12. As a result, the spout 34 fills the drain trap (not shown) with water and causes a siphon action. As a result, a suction force for sucking the water in the bowl portion 12a is generated, and the bowl portion 12a can be efficiently washed with a small amount of washing water.

The toilet bowl 12 is, for example, a siphon-set type toilet bowl. The wash water supply channel 30 is a wash water supply channel that supplies wash water to the water sealing portion 12c of the toilet bowl 12. The wash water supply channel 30 may be referred to as, for example, a Zet headrace. The spout 34 may be referred to as, for example, a Zet spout (Zet hole) or the like.

As shown in FIG. 1, at least a part of the wash water supply channel 30 is located above the sealing level WL2. The wash water supply channel 30 takes in air into at least a part of the bowl portion 12a located above the sealing water level WL2 in a state where the wash water is not supplied into the bowl portion 12a. The wash water supply channel 30 takes in air into a part of the above through, for example, a spout 32 provided in the upper part of the bowl portion 12a. As a result, the water level in the wash water supply channel 30 becomes substantially the same as the water level in the bowl portion 12a.

The detection unit 20 detects the water level of the water level change unit WVP. In this example, the detection unit 20 detects the water level of the wash water supply channel 30. As a result, in the detection unit 20, is the water level in the bowl portion 12a lower than the full water level WL1 and higher than the sealed water level WL2 through the water level of the wash water supply channel 30 (water level change portion WVP)? Detect whether or not.

As described above, the water level in the wash water supply channel 30 is substantially the same as the water level in the bowl portion 12a. In this case, the detection unit 20 is provided at a position lower than the full water level WL1 and higher than the sealing level WL2. However, the position of the detection unit 20 is not necessarily limited to the position between the full water level WL1 and the sealed water level WL2. The detection unit 20 may be arranged so that at least the detection range is located between the full water level WL1 and the sealed water level WL2.

The inner wall surface of the wash water supply channel 30 has a vertically extending portion 30a. The vertically extending portion 30a is located at a height of the water level that changes in conjunction with the water level in the bowl portion 12a. That is, in this example, the vertically extending portion 30a is located between the full water level WL1 and the sealing water level WL2. The vertically extending portion 30a extends in the vertical direction rather than in the horizontal direction. Here, "extending in the vertical direction rather than the horizontal direction" means, for example, a state in which the angle of inclination with respect to the horizontal is greater than 45 degrees and 90 degrees or less. The detection unit 20 detects the water level of the vertically extending portion 30a of the wash water supply channel 30.

As described above, according to the toilet system 2 and the toilet device 10 according to the present embodiment, the water level changing unit WVP in which the detecting unit 20 changes the water level in conjunction with the water level in the bowl portion 12a of the toilet bowl 12. It is detected whether or not the water level in the bowl portion 12a is lower than the full water level WL1 and higher than the sealed water level WL2 through the water level of the water level changing portion WVP. As a result, even when filth containing water adheres to the bowl portion 12a, it is possible to prevent erroneous detection of the filth as water and erroneous determination that clogging has occurred. Therefore, it is possible to provide the toilet system 2 and the toilet device 10 that can more accurately detect the clogging of the toilet bowl 12.

Further, in the toilet system 2 and the toilet device 10, by setting the washing water supply channel 30 for supplying the washing water into the bowl portion 12a as the water level changing portion WVP, the existing configuration can be used without using a special configuration. It can be used to prevent false detection of filth as water.

Further, in the toilet system 2 and the toilet device 10, the washing water supply channel 30 for supplying washing water to the water sealing portion 12c of the toilet bowl 12 is set as the water level changing portion WVP, so that the rim portion on the upper edge of the bowl portion 12a is formed. Clogs can be detected at a lower water level than the wash water supply channel 38 for supplying wash water. As a result, it is possible to more reliably prevent the washing water from overflowing from the upper edge of the bowl portion 12a.

Further, in the toilet system 2 and the toilet device 10, at least a part of the washing water supply channel 30 is positioned above the sealing water level WL2, and air is taken into at least a part of the toilet system 2 and the toilet device 10 in a state where the washing water is not supplied. Thereby, the water level of the washing water supply channel 30 can be made substantially the same as the water level of the bowl portion 12a. As a result, the detection range of the detection unit 20 may be set between the full water level WL1 and the sealing water level WL2 of the bowl portion 12a, and the positioning of the detection unit 20 with respect to the wash water supply channel 30 can be facilitated. can.
