JP2017023967A - Measuring / notifying device for water purification cartridge replacement time of water purifier - Google Patents

Abstract

PROBLEM TO BE SOLVED: To suitably notify a user of replacement timing of a water purification cartridge by integrating frequency of opening and closing of a lid when supplying water.SOLUTION: Frequency of opening and closing of a lid 2 of a water purifier equipped with an attachable-detachable cartridge 9 housing a filter medium therein when supplying water is detected and integrated, or a volume of a raw water (tap water) in a storage 5 is integrated as an amount of purified water, and further, replacement timing is also notified from a use time of the water purification cartridge. Detection of the opening and closing of the lid is performed by vibration detection at opening and closing, detection by magnetism, detection by light, detection of pressure at opening and closing of the lid, or detection by a switch. Depending on a detection method, a measurement and notification device 3 is not necessarily used as a set with the water purifier and is usable as a single unit.SELECTED DRAWING: Figure 1

Description

  This invention is an invention which puts in the water purifier which uses a detachable water purification cartridge, and accumulate | stores the amount of purified water correctly.

  In the first conventional method, the amount of daily use is determined arbitrarily, and the passage of time is appropriately displayed as the life of the water purification cartridge. Second, the water sensor detects that the raw water has been poured and accumulated. Counting the number of times of water injection and calculating the life of the water purification cartridge. Third, instead of the second water sensor, a small lid that automatically opens and closes by the water pressure is added to the lid, and the number of times of water injection is counted.

However, even in the second method for accurately confirming the amount of water purified by the water purification cartridge, when the water purifier is moved or used, or erroneously counts with splashes, and because the sensor or counter contacts the water, There was a failure due to water intrusion from the gap or the battery replacement part.
In the third method, the water inlet may be inadvertently pushed by hand, or it may be miscounted depending on how it is poured. There was a problem with.
In addition, even for water purifiers that have already been used, accurate measurement of the amount of purified water is provided by selling the measurement and notification device alone.

As a new means for solving these problems, the normal operation of opening the lid and pouring raw water when water is poured may be counted by detecting the opening and closing of the lid. The opening / closing of the lid is detected by magnetism, light, switch, or vibration, and it is counted that a certain amount of water has been poured into the portion where raw water is poured and stored. By measuring, the time of replacement of the water purification cartridge, the number of times of water injection as required, or the amount of water purification is also displayed.

  It is possible to measure the amount of purified water or the number of times of water purification, and it is possible to install it by attaching this device to the lid of the water purifier, regardless of the type of water purifier already used. Available.

Water purifier lid and body. If the measurement notification device (3) including the notification unit 12 of the amount of use of the water purification cartridge and the replacement time is attached to the lid, and the lid does not detect the opening / closing of the lid due to vibration, An example in which a lid opening / closing detector 1 (4) is attached to the end of the measurement notification device and a lid opening / closing detector 2 (8) is attached around the body. Another pattern of the measurement notification device (3) including the notification unit. The lid of the water purifier and the main body, a handle was attached to the lid, and a notification unit 12 and a pressure detection unit 16 for opening and closing the lid were provided there.

A measurement notification device 3 including a water purification cartridge replacement time notification unit 12 or 14 is installed on the lid 2 of the water purifier, and detection of lid opening / closing is detected by any one of the following methods. Detection of vibration, magnetic detection between the water purifier main body 6 or detection by light, pressure of meshing with the main body 6 or pressure of a portion where a finger is put on when removing the lid is a pressure sensor or Is a switch provided to operate when opening and closing the lid with a switch, and a switch provided to operate when opening and closing the lid with a hinge.
The above detection results are integrated as the number of times of opening and closing, or are integrated as a certain amount of purified water to the cartridge. The pressure detection unit 16 detects the pressure of the handle when the lid is removed.
Moreover, although the opening and closing of the lid with a hinge is not shown in the drawings, the water purifier has a structure in which the main body 6 and the lid 2 are opened and closed with a hinge. Further, detection of lid opening / closing is incorporated in the measurement / notification device (3), a method using the lid opening / closing detection unit 1 (4) and the lid opening / closing detection unit 2 (8), or the various detection methods described above. There is a method according to.
Further, for the sake of hygiene, notification of the replacement time from the use period of the cartridge is also used.
As a method for resetting the notification unit, the push button switch 13 is provided, or a long press of 13 may be performed, or the notification unit 12 including a switch function is reset by being pressed.

The parts of the above various detection methods may be housed in a package for waterproofing. In addition, the measurement notification device (3) can be used as a single unit without being set as a water purifier.
