Description

  The present invention relates to a toilet device, and more particularly to a toilet device in which a liquid detergent is poured from a detergent tank into washing water for washing a bowl portion of the toilet bowl to perform detergent cleaning.

  In the toilet device, the liquid detergent stored in the detergent tank is put into the washing water flow path for supplying washing water to the bowl part of the toilet bowl, and the bowl part is automatically washed with detergent using the washing water containing detergent. It is necessary to regularly replenish liquid detergent into the detergent tank.

  However, since the detergent tank is stored in the toilet bowl, the remaining amount of detergent cannot be grasped from the outside. For this reason, it is generally determined that the detergent has disappeared when bubbles no longer appear during cleaning of the toilet bowl. In such a determination, it is easy to overlook the foam, and there is a risk that toilet bowl cleaning may be performed without detergent.

  Therefore, conventionally, in Patent Document 1, based on the number of toilet users detected by the detection device and the counter device, the supply amount of the cleaning liquid is calculated by the cleaning liquid supply amount calculating means, and the liquid detergent is supplied by the cleaning liquid replenishment / replacement time notification means. There is known a maintenance management system for notifying that it is time to replenish / replace.

  By the way, the viscosity of chemicals such as detergents has a temperature dependency that is higher as the temperature is lower and lower as the temperature is higher. Therefore, if the temperature of the detergent changes, the amount of detergent used and the flow rate from the detergent tank As a result, the amount of detergent used per day changes throughout the season and day and night. In particular, when the detergent tank is installed away from the bowl, the detergent travel distance becomes long, and the influence of room temperature becomes large.

  For this reason, as in the conventional example shown in Patent Document 1, in the notification system that calculates the supply amount of the cleaning liquid and periodically displays a warning, the remaining amount of the detergent tends to vary due to a change in room temperature. . As a result, there is a problem that the notification timing is likely to vary.

  The present invention has been made in view of the above circumstances, and the object of the present invention is to minimize variations in notification timing even when the room temperature changes, and to avoid toilet cleaning without a detergent. It is providing the toilet device which can do.

  In order to solve the above-mentioned problem, the first invention is a toilet apparatus for cleaning a toilet bowl by putting a liquid detergent from a detergent tank into cleaning water for cleaning the bowl part of the toilet bowl. And a viscosity measuring means for measuring the viscosity of the liquid detergent discharged from the detergent tank or a value corresponding to the counter, and a notification means for displaying an external warning when the predetermined number of washings is reached, A cleaning frequency correction circuit that corrects the predetermined cleaning frequency by converting the amount of detergent used per time into a detergent discharge amount corresponding to a change in viscosity or a corresponding value is provided.

  In a second aspect based on the first aspect, the viscosity measuring means preferably includes a temperature sensor for detecting a room temperature around the detergent tank.

  In the present invention, by adjusting the predetermined number of times of performing the notification according to the change in the room temperature, variation in the notification timing can be suppressed even when the room temperature changes, and toilet cleaning without a detergent can be avoided. Is.

It is a block diagram relevant to the control part of the toilet device of this invention. It is a schematic block diagram of a toilet device same as the above.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The basic structure of the toilet device 1 is shown in FIG. The upstream end of the water supply path 6 is connected to a water pipe (not shown), and the downstream end is disposed facing the bowl portion 4. A water supply control valve 12 comprising an electromagnetic valve is provided in the middle of the water supply path 6, and the presence or absence of water supply to the water supply path 6 is switched by opening and closing the water supply control valve 12. An air supply path 13 for taking air into the water supply path 6 is connected to the water supply path 6 downstream of the water supply control valve 12. The other end side of the detergent supply path 5 to be described later is connected to the downstream side of the connection portion of the water supply path 6 with the air supply path 13.

  The toilet device 1 is of a turn trap type and includes a flexible trap cylinder 14. One end of the trap cylinder 14 is connected to a drain cylinder 15 projecting rearward from the lower part of the bowl 4, and the other end is a free end. It has become. The trap cylinder 14 is rotated by a motor (not shown) to form a trap structure with the opening on the free end side facing upward, and an external pipe (not shown) from the discharge hole with the opening on the free end side facing downward. To be drained) can be selected.

  In the space provided behind the bowl part 4 inside the toilet bowl, a detergent tank 2 for storing the liquid detergent 3 and a circulation pump for sending the liquid detergent 3 in the detergent tank 2 to the external circulating detergent path 17 19 and a detergent supply path 5 having one end connected to the horizontal pipe portion of the circulating detergent path 17 and the other end connected to the water supply path 6. In FIG. 2, 16 is a toilet lid, and 22 is a valve for opening the circulating pump 19 during operation and closing it when stopped to prevent detergent leakage.

  The circulating detergent path 17 includes an outward connection pipe 17a and a return connection pipe 17b which are L-shaped in parallel when viewed from the side. The horizontal pipe portions of the forward connection pipe 17a and the return connection pipe 17b are continuously formed in a U-shape, and the vertical pipe portions of the forward connection pipe 17a and the return connection pipe 17b are formed in the detergent tank 2. Each of the caps 18 is inserted into the detergent tank 2. By operating the circulation pump 19, the liquid detergent 3 in the detergent tank 2 circulates in the circulation detergent path 17 so that the liquid detergent 3 is sucked out from the forward connection pipe 17a and returned from the return connection pipe 17b. Yes. The detergent replenishing port 20 of the detergent tank 2 is closed with a removable lid 21.

  At the time of toilet cleaning, if the water supply control valve 12 is opened while the circulation pump 19 is operated, air is mixed from the air supply passage 13 into the water flowing into the water supply passage 6 from the water pipe. At the same time, the valve 22 is opened by the negative pressure generated in the detergent supply path 5 and a part of the liquid detergent 3 circulating in the circulating detergent path 17 is sucked into the water supply path 6 via the detergent supply path 5. Mixed into the wash water. As a result, a cleaning liquid having a high cleaning effect including bubbles mixed with the detergent is discharged to the bowl portion 4 to perform cleaning with the detergent.

  Next, the control operation at the time of detergent replenishment will be described.

  As shown in FIG. 1, the toilet device 1 operates a counter 7 that stores the number of times the toilet is cleaned, a notification unit 8 that displays a warning when a predetermined number of cleanings is reached, and a notification unit 8. The control part 10 to be provided is provided. Examples of the notification means 8 include a warning sound by a buzzer or a lighting display by a lamp or a light emitting diode.

  First, a case where a change in room temperature is not considered will be described. When the amount of detergent used per time discharged from the detergent tank 2 is m and the number of times of cleaning is n, the amount of detergent used m per time is determined in advance, and the counter 7 can grasp the number of times of cleaning n. Therefore, when the capacity of the detergent tank 2 is A and the remaining amount of the detergent is B (for example, 10% or less of A), the predetermined number of times n of performing the notification is calculated from the relationship of A− (m × n) ≦ B. Can be sought. The control unit 10 operates the notifying means 8 to display a warning to the outside when the predetermined number of times of cleaning n is reached.

  By the way, the detergent usage amount m per time changes depending on the temperature. That is, the liquid detergent 3 which is a chemical solution has an inherent viscosity, and the temperature-viscosity characteristic is such that the viscosity is low when the temperature is high, and the viscosity is high when the temperature is low. For this reason, the detergent usage amount m per time tends to vary according to the change in room temperature, and as a result, the detergent remaining amount B cannot be accurately grasped.

  Therefore, as shown in FIG. 1, the controller 10 of the toilet device 1 sets the detergent usage amount m (predetermined numerical value) per one time to a detergent discharge amount (detected at a detected room temperature). Correction coefficient data for conversion into (detergent amount discharged from the detergent tank 2) is stored in advance. Furthermore, the viscosity measuring means 9 for measuring the viscosity of the liquid detergent 3 or a value corresponding thereto (for example, a viscosity detection signal) and the number of washings for correcting the predetermined number of washings n for performing notification according to the change in viscosity. A correction circuit 11 is provided.

  In this example, the viscosity measuring means 9 includes a temperature sensor 9a that detects the room temperature around the detergent tank 2, and a viscosity calculation circuit 9b that converts the viscosity of the liquid detergent 3 from the temperature detected by the temperature sensor 9a. .

  The room temperature detected by the temperature sensor 9a and the number of cleanings n counted by the counter 7 are periodically fed back to the control unit 10. The viscosity calculation circuit 9b of the control unit 10 calculates the viscosity of the liquid detergent 3 from the detected room temperature based on the viscosity-temperature conversion data indicating the correspondence between the viscosity and the temperature. The cleaning frequency correction circuit 11 is a correction coefficient corresponding to the viscosity calculated by the viscosity calculation circuit 9b on the basis of correction coefficient data indicating the correspondence between the viscosity and the amount of detergent used in advance stored in the memory of the control unit 10. Find μ. Then, the detergent discharge amount (m × μ) corresponding to the change in viscosity is calculated by adding the correction coefficient μ to the detergent usage amount m per time, and correction is made to the predetermined number of times n of performing the notification. .

  That is, when the capacity of the detergent tank 2 is A and the remaining amount of the detergent is B (for example, 10% or less of A), the detergent discharge amount corresponding to the viscosity change from the relationship of A− (m × μ × n) ≦ B If (m × μ) is known, the detergent remaining amount B can be accurately grasped without being affected by the change in room temperature. The cleaning frequency correction circuit 11 corrects a predetermined cleaning frequency n for performing the notification based on the accurate detergent remaining amount B. Specifically, when the detergent discharge amount (m × μ) decreases with a decrease in room temperature, the predetermined number of cleanings n is gradually increased according to the decrease width, and the detergent discharge amount (m × μ) with a rise in room temperature. ) Increases, the predetermined number of cleanings n is gradually reduced according to the increase. As a result, even when the room temperature changes, the notification timing is less likely to vary. As a result, it is possible to avoid toilet cleaning without detergent and notification at a stage where there is a sufficient amount of detergent remaining. This effect is extremely effective not only in the case of toilets in general households, but also in that the burden on maintenance managers can be sufficiently reduced especially when maintenance managers manage them collectively, such as many toilets installed in public facilities. It is.

  Further, in this example, the room temperature and the number of times of cleaning n are fed back to the control unit 10, and the amount of detergent used per time is converted into the amount of detergent discharged according to the viscosity change, and the predetermined number of times of cleaning n is corrected. This is a conversion method. Therefore, for example, it is not necessary to control the rotation amount and driving time of the circulation pump in accordance with a change in room temperature, and to increase or decrease the amount of detergent used per time, and the control operation and circuit structure of the control unit 10 can be reduced. It can be simplified. In addition, since the temperature sensor 9a only needs to be disposed outside the detergent tank 2, there is an advantage that it does not take time to install the temperature sensor 9a.

  In the above embodiment, the case where the temperature sensor 9a and the viscosity calculation circuit 9b are used as the viscosity measuring means 9 has been described as an example. However, the viscosity calculation circuit 9b is omitted and the correction coefficient is directly applied from the temperature sensor 9a. It is good also as composition which asks for data.

  Further, the viscosity measuring means 9 may be configured to directly measure the viscosity of the detergent by providing a viscometer or a flow rate sensor inside the circulating detergent path 17 or inside the detergent supply path 5 instead of from the temperature.
