JPH10118641A - Stopcock-direct water purifier - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain sanitary palatable drinking water by making it possible to simply display the file of the cartridge of a water purifier by the indicator integrally constituted along with the water purifier and making it possible to accelerate the replacement of the cartridge before life arrives. SOLUTION: An indicator 5 uses a primary battery as a power supply amt. displaying the use amt. of water being one index showing the life of a water purifying cartridge 4 on a display part such as an LED as the value proportional to water quantity to let a user know the proper life of the cartridge 4 to tell the replacing period of the cartridge integrally incorporated in an indicator 5 in a stopcock direct-coupled water purifier.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to prevent the harmful effects of using a water purifier for a long time without using the water purifying effect by notifying a user of the service life of the water purifier so that the user can easily understand it. It is an object.

[0002]

2. Description of the Related Art Activated carbon is generally incorporated in a cartridge of a water purifier, and its purpose is to remove excess residual chlorine in tap water to provide delicious and body-friendly water for drinking. In proportion to the amount of water used, the ability to remove residual chlorine decreases and the amount of water decreases due to clogging of foreign matter.
Useless.

[0003]

As the most common examples of measuring and controlling the amount of water, there are a so-called water meter for measuring the amount of water used for water supply and a water meter for controlling the amount of bath water to a fixed amount. However, there is no water purifier directly connected to the water purifier which determines the life of the cartridge with a simple indicator incorporated in the water purifier itself.

An object of the present invention is to solve the above-mentioned problem by measuring the amount of water in the cartridge life or both the amount of water and the usage time, and displaying the measured signal in digital or analog form.

[0005]

According to a first aspect of the present invention, there is provided:
Using a primary battery as a power supply, the amount of water used, which is one indicator of the life of the water purification cartridge, is indicated by an LED in proportion to the amount of water.
And the like, the indicator that informs the user of the appropriate life of the cartridge and alerts the user to replace the cartridge is integrated into the water tap water purifier.

A second structure of the present invention is that, in the first structure, the shorter of the amount of used water and the total elapsed time of use has been displayed in which the life of the cartridge is set to the attained life in advance.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a water faucet directly connected to a water faucet. The water purifier comprises a water faucet mounting portion 2, a switching valve portion 3, and a water purification cartridge 4. The switching valve portion 3 has an indicator 5 for measuring a flow rate. .

As shown in the water path diagram in FIG. 2, the water from the faucet 6 is supplied to the raw water outlet 8 by switching the lever 7 when the raw water is used.
When the purified water is used, the tap water is purified via the cartridge 4 by switching the lever 7 and flows out from the purified water outlet 9.

In the present embodiment, the amount of purified water is measured by an indicator 5 integrated into the switching valve section 3, and the structure thereof is as shown in FIG.
It comprises an operation unit 11 for accumulating a value proportional to the detected water amount and a display unit 12 for displaying the operation result.

Reference numeral 13 denotes a primary battery such as lithium.

The detection unit 10 of the indicator 5 uses, for example, a small water turbine in which a permanent magnet is embedded in a blade that rotates by a water flow in a water channel, and that the rotation speed is increased in proportion to the amount of water. The magnetic force is sensed by the Hall element, accumulated and calculated by the arithmetic unit 11, and the result is taken out as a signal proportional to the amount of water, whereby the amount of water can be digitally displayed on the display unit.

The display unit 12 can display the amount of water numerically as shown in FIG. 4 by using an LED element or an LCD element, or can display it analogously as a bar graph as shown in FIG. it can.

Further, for example, by adding a clock function to the microcomputer of the arithmetic unit as shown in FIG. 5, it is possible to take into account that the activated carbon in the cartridge is degraded by the atmosphere or stagnant water even when the water does not flow along with the amount of water used. Alternatively, the life of the cartridge may be displayed by counting the elapsed time of leaving the cartridge, comparing the life of the preset amount of water with the life of the cartridge, and displaying the numerical value of the life that is reached earlier.

The present invention displays the life of the cartridge of the water purifier for the purpose of always obtaining fresh drinking water as described above, and includes factors essential for hygiene.

[0016]

According to the present invention, the life of the cartridge of the water purifier can be easily displayed by the indicator integrated with the water purifier, and the replacement of the cartridge can be promoted before the life is reached, so that sanitary and delicious drinking water can be provided. Obtainable.

Further, according to the present invention, it is possible to display the life when the cartridge is left unused for a long period of time together with the amount of water used, and to directly connect a faucet having a function that matches the era of obtaining safe drinking water. A water purifier can be provided.
