Description

  The present invention relates to waste to be discharged and transported outside the toilet when washing the toilet (hereinafter, in this specification, not only excrement such as large and small urine released from the user's body, but also toilet paper such as toilet paper) In conjunction with this, the toilet bowl washing sequence is changed when an abnormal value is detected such that the amount of waste that is dumped in the bowl 23 is collectively referred to as “exhaust”). In particular, it is suitable for preventing the discharge from being discharged from the toilet or preventing the occurrence of clogging in the sanitary equipment piping without realizing the predetermined transport length even if it can be discharged. It is an invention related to a toilet device.

  In the conventional toilet flushing sequence, the upper limit of the amount of waste is assumed based on the survey results of the distribution of the amount of excretion discharged by multiple users during normal defecation, and the upper limit amount of waste is discharged and transported. A sufficient cleaning pattern and amount of water are set. And since the distribution of the amount of excrement varies greatly depending on the mode of stool (large and small), there are some that change the amount of washing water based on information on this mode (see, for example, Patent Document 1).

  In addition, depending on the mode of the defecation equipment, not the user's stool mode, for example, the type of toilet such as a siphon type or siphon set type, the structure of a toilet such as a standard type or a water-saving type, or Some have a means capable of changing the apparatus setting to an optimum amount of washing water according to the drainage form such as floor drainage and wall drainage (for example, see Patent Document 2).

  Furthermore, in recent years, attention has been paid to the saving of this washing water as a resource saving, not only trying to reduce the absolute amount of washing water by improving the washing and discharging capacity of the toilet itself, but also for various uses. A toilet device is also conceivable in which the amount of washing water can be selected and specified in more stages so that more water can be saved by responding more closely to the mode of stool (see, for example, Patent Document 3).

  However, in any of the cases described above, the amount of washing water is defined in advance assuming the upper limit of the amount of waste to be discharged and transported. Even if the amount of water is selected, if there is an amount of waste in the urinal that exceeds the upper limit of the assumed amount of effluent, the effluent cannot be discharged from the urinal. The assumed predetermined conveying length could not be realized, and there was a risk of clogging due to waste accumulation in the sanitary equipment piping communicating with the toilet.

As the pipe line opening / closing means, an on-off valve and a pipe switching valve, or a configuration normally used such as an opening / closing valve in each pipe line can be applied.

  With the configuration as described above, the toilet flushing water supply means 24 is generated by the toilet flushing signal from the toilet flushing method selection means 63 such as the washing selection switch provided in the operation / display unit 6 after the user's excretion is completed. Performs the following toilet flushing sequence: That is, first, cleaning water is supplied to the rim water discharging means 25 (hereinafter, this water supply cleaning is referred to as pre-rim cleaning) to wash the inside of the bowl 23 with water. Next, cleaning water is supplied to the trap water discharge means 26 via the branching portion 27 to the trap 21 (hereinafter, this water supply cleaning is referred to as “jet cleaning”), the siphon is activated, and the waste water 22 mixed with the discharge is discharged into the building. Discharge to piping. When the discharge is completed, cleaning water is supplied again to the rim water discharge means 25 (hereinafter, this water supply cleaning is referred to as post-rim cleaning), and the inside of the bowl 23 is washed again. Water 22 is supplied to restore the stored water level.

  Instructing the toilet flushing water supply means 24 to execute the above-described toilet flushing sequence is the toilet flushing water supply control means 91 incorporated in the control unit 9, and in response to the toilet flushing signal from the operation / display unit 6. In response, the execution of a predetermined toilet flushing sequence is instructed.

  The contents described so far are the same in the conventional toilet device. However, in the toilet device 1 embodying the present invention, in the toilet cleaning operation, the normal pattern is executed as the toilet cleaning sequence. In addition to the mode, there is an abnormal mode in which a special pattern is executed when the amount of the above-mentioned discharged material to be dumped in the bowl 23 is larger than the amount normally assumed. Hereinafter, the toilet cleaning operation at the time of abnormal discharge amount, which is a feature of the present invention, will be described in detail.

The toilet device 1 in the present embodiment is provided with a control unit 9 that controls each operation of the entire device, and the control unit 9 detects the amount of discharged material that estimates the amount of discharged material in the bowl 23. Means 8 and waste amount abnormality determining means 92 for determining whether or not the amount of discharged waste is equal to or greater than a predetermined amount for the toilet cleaning method selected by the user are provided. .

  The discharged amount detection means 8 includes a stored water change amount measuring means 81 for measuring a change amount of the stored water 22 before and after the defecation action, and according to the amount of change in the stored water due to the defecation action obtained from the stored water change amount measuring means 81, Estimate the amount of emissions.

  In the present embodiment, as the stored water change amount measuring means 81, the water pressure change generated in the measurement pipe line 82a led from the branch portion 27 provided in the middle of the above-described jet water supply pipe line 26a is measured by a pressure sensor, and the stored water level is measured. It is provided with a stored water level measuring means 82 for determining the water level, and continuously measures the water pressure change during the defecation action while keeping the water level at the start of the defecation action as the overflow water level, and the water pressure change obtained It is set as the structure which obtains the amount of stored water changes by converting using the stored calibration curve. According to this method, since the configuration is simple, a low-cost apparatus is obtained.

  In order to determine the change in the amount of accumulated water more accurately, the measurement is started with the water level at the start of defecation being reduced by a predetermined amount from the overflow water level, and the change in the water level is measured by the accumulated water level measuring means 82. It is also possible to do.

  As another example of the stored water amount measuring means 81, the amount of stored water change is obtained in the same manner as this embodiment by measuring the stored water level using an ultrasonic sensor installed on the outer surface of the Western-style toilet 2. With this configuration, the Western-style toilet 2 is efficient and preferable without requiring a large process.

  The operation / display unit 6 is provided with a toilet cleaning method selection means 63 configured by, for example, a large / small washing selection switch, and an input result of the toilet cleaning method selection means 63, that is, a toilet cleaning method of stool cleaning or urine cleaning. The type is output as information to the discharge amount abnormality determining means 92.

  The waste amount abnormality determining means 92 is a toilet bowl of stool washing or urine washing designated by the amount of waste obtained by the waste quantity verification means 8 and the toilet bowl washing method selection means 63 provided in the operation / display unit 6. In consideration of information on the type of cleaning method, it is determined whether or not the amount of the waste dumped in the stored water 22 by the defecation action is an abnormal state exceeding a predetermined amount.

When the discharge amount abnormality determining unit 92 determines that the abnormal value exceeds the predetermined value, the waste amount abnormality determining unit 92 causes the toilet flushing water supply control unit 91 to execute the toilet flushing water supply unit 24. A signal for changing the toilet flushing sequence for the abnormal mode is output.

  FIG. 3 is a list showing examples of changing the toilet flushing water amount executed in the toilet flushing operation sequence of the toilet device 1 in the present embodiment. A method for selecting and determining the operation mode of toilet cleaning in the present embodiment will be described below with reference to FIG.

  In general, the volume of excreta excreted in the bowl of a toilet bowl in a single excretion is statistically estimated from the results of measurements in many cases. The maximum amount of stool in the fecal excretion is 250 mL. The maximum amount of urine at the time of the action is 800 mL, and if it exceeds that, it is abnormal in each action, and in the case of stool, it cannot be discharged from the Western-style toilet 2 or the transport length in the drainage pipe is 10 m. There is a risk that only a distance that does not satisfy the standard can be conveyed.

  Therefore, in FIG. 3, when the stool washing is selected by the user, 4.8L is used, and when the urine washing is selected, 4L is used as the toilet flushing water amount. And, when the amount of effluent obtained as a result of a single excretion exceeds a predetermined value, that is, 250 mL of stool and 800 mL of urine excretion, the amount of effluent determination means 92 determines that the amount of effluent to be discharged is abnormal Indicates that the amount of flushing water in the toilet bowl is changed to 6L.

When defecation is performed, toilet paper is often used. After use, toilet paper is dumped into the bowl of the toilet bowl, so that it can be transported outside the toilet bowl. Here, the amount of general toilet paper used is a maximum of 5 m based on the same survey results as the above-mentioned excrement, and when it is used more than that, it is in an abnormal state and cannot be discharged from the Western-style toilet 2 For example, there is a risk that the standard of the conveyance length of 10 m in the drainage pipe defined by Better Living Foundation may not be satisfied.

  Therefore, it is also possible to make it applicable as an emission of the present invention. In that case, as shown in FIG. 3, the determination of the discharge amount abnormality determination unit 92 is performed by providing the toilet paper length measuring unit 71 in the paper roll 7 and calculating the amount of toilet paper required. What is necessary is just to set it as the structure determined in addition to the parameter of abnormality determination performed by the abnormality determination means 92. FIG.

  In addition, although the method of measuring the volume of discharged matter through the change in the water level of the stored water was shown, other change indexes such as temperature change and conductivity may be used, and the size of stool is recognized by image recognition. Or a method of measuring the moving speed of the stool with a microwave sensor or the like.

  FIG. 4 is a timing chart showing each change example of the toilet flushing sequence employed in the abnormal mode in FIG. 3 of the toilet of the present invention in comparison with the normal mode. The change of the toilet bowl washing sequence corresponding to various abnormal states in this embodiment will be described below using FIG.

  (A) of FIG. 4 has shown the toilet bowl washing | cleaning sequence example of the normal mode used as a reference | standard when the excretion amount is below the amount assumed beforehand for the comparison. FIG. 4B shows an example of a toilet flushing sequence when the amount of toilet paper used is abnormal. In this case, the conveyance length in the drainage pipe may not reach due to the frictional resistance in the pipe. It is assumed that the amount of water for front rim cleaning is increased in order to improve the conveyance length. FIG. 4 (c) shows an example of a toilet flushing sequence when the amount of excretion of stool out of the excreta is abnormal. In this case, it is necessary to place importance on discharging from the Western-style toilet 2. From this, it is shown that the amount of water for washing the zet is increased in order to improve the discharge capacity. Furthermore, FIG. 4 (d) shows an example of a toilet flushing sequence when the amount of excretion of urine is abnormal among the excreta, and in this case, it is necessary to place importance on the water exchange rate of the stored water. It has been shown that the amount of water for post-rim cleaning is increased in order to improve the water exchange rate.

  FIG. 4 is an example of increasing the amount of cleaning water used in one cleaning even if the above-mentioned concept is adopted. In any case, the operation for each discharging process is performed by using a constant water discharge rate. An example is shown in which the duration is changed to be longer than usual.

  This method can be applied at a low cost because the configuration of the water supply means such as the water supply valve is widely used, but it can be manufactured at a low cost. Alternatively, a method of increasing the amount of washing water may be used.

  FIG. 5 is a flowchart showing the operation of the toilet device 1 in the present embodiment designed based on the above concept. The operation flow will be described below with reference to FIG.

  In step S101, the human body detection sensor detects the user. In step S102, an operation for preparing for detection is performed in order to measure the amount of discharged matter. When it is detected in S103 that the user is seated on the toilet seat, the water level measurement is started in S104, and the water level of the accumulated water 22 (water level before excretion) is stored.

  After the user completes the excretion and the excretion of the toilet paper, the user performs a toilet cleaning operation specifying whether the stool is a stool or not in S105. Prior to the start of washing in S106, the water level at that time (water level after excretion) is measured to calculate the change in the water level before and after excretion, and the amount of discharged matter is estimated in S107 considering each information. The estimated discharge amount is compared with a predetermined value in S108 to select a toilet flushing sequence.

  If the estimated amount of discharged matter is smaller than a predetermined value, it is determined that the amount of discharged matter is normal, and a normal sequence is selected in S109 to be a normal water discharge amount. A large-capacity sequence with a larger water discharge amount than the normal water discharge amount is selected according to the above. S111 is a step of performing toilet cleaning according to the selected sequence, and the toilet cleaning sequence is stopped after the toilet cleaning is completed.

  FIG. 6 is an explanatory view showing another washing water amount changing method for toilet bowl washing applicable to the present invention. With reference to FIG. 6, another method for changing the amount of washing water in the toilet device 1 in the present embodiment will be described below.

  The example described so far in FIG. 3 shows a method of increasing the amount of washing water by a certain amount when it is detected that the amount of discharge is an abnormal value compared to a predetermined value. May change the amount of washing water according to the amount of discharged matter. This figure is an example in the case of only stool in which the effluent in the present invention is excretion, and schematically shows the relationship between the stool excretion volume (volume) distribution and the toilet flushing water amount of many users. is there.

  Thus, since the volume of a general stool is normally a distribution of 100 to 250 ml, 250 ml is defined as a predetermined amount of excretion, and the amount of washing water when the amount of excretion is less than this predetermined value is determined in advance. A certain amount of water is discharged. However, in very rare cases, the amount of excretion of stool may exceed a predetermined value. In this case, a large amount of jet water is necessary for discharging to the outside of the Western-style toilet 2, as shown in the figure. In addition, the amount of water discharged from the jet is increased in accordance with the amount of discharged matter.

In the case of this example, the amount of rim water discharged before reducing the frictional resistance in the drainage pipe and the amount of post-rim water discharged after improving the water exchange rate of the stored water 22 are not expected to be very effective. It is an algorithm that increases by a certain percentage according to exceeding a predetermined value.

  Since the relationship between the amount of washing water and the discharge performance / carry-out performance in each process of the Western-style toilet 2 is different for each type of toilet, the treatment content when an abnormality is detected may be selected for each type of toilet. That is, for example, when the toilet bowl discharge performance is easily affected by the amount of toilet paper, the method for changing each amount of water discharge, such as increasing the amount of water discharged from the toilet paper to the abnormal value of toilet paper, is as described above. Various methods can be selected without being fixed to the contents.
