Description

[Detailed explanation of the idea] The present invention relates to a water purifier for home use.

An object of the present invention is to provide a water purifier in which the water purifying function is always properly exhibited by appropriately setting and displaying the replacement period of the cartridge built into the water purifier on a display board.

That is, in the present invention, a display section 3 is provided on the rear end surface of a water purifier main body 1 that is detachably attached to a water tap, and the display section 3 displays information such as the time to replace the water purification cartridge 2.
consists of a scale ring 5 with a number 4 attached, and an indicator ring 7 with an index 6 indicating the number, and the scale ring 5
This is a water purifier in which one side of the indicator ring 7 is relatively rotatable.

The illustrated embodiment includes an inlet 9 for attaching a mounting member 8 to a faucet appliance, and a faucet 1 for outflowing purified water or raw water.
A display section 3 is provided on the base end surface of a water purifier main body 1 having 0 and 0 at both ends. It is rotatably supported on a valve portion 11 at the base end of the main body by a support shaft 12, and one indicator 6 for indicating the number 4 is attached to the upper part of an indicator ring 7 located on the outer periphery of the scale ring 5. There is. Therefore, when replacing the cartridge 2, if you match the month with the index 6 above, the month indicated by the number 4' on the opposite side will be the expiration month for replacement, which is very easy to understand. This six-month period is an example based on a certain amount of water used, and may naturally change. 13
14 indicates a dial having a scale ring 5 on its periphery, and 14 indicates a knob at the center thereof. Incidentally, the scale ring 5 and the indicator ring 7 only need to be in a relative moving relationship, and either can be freely set on the fixed side or the rotating side, and the positional relationship is not limited to the example shown.

The water purifier main body 1 includes a switching valve 15 that passes horizontally through the valve portion 11, and a cartridge extrapolation that allows raw water from the inlet 9 to pass through the first through hole 11a directly to the faucet 10 at one switching position. A water pipe 16 that also serves as a body, and a pipe that fits inside the base end opening of the pipe 16,
The other side is a chamber 1 that contacts the valve portion 11 and into which water flows from the second through hole 11b at the other switching position of the switching valve 15.
7 and a diaphragm 18 in the chamber 17.
and a through hole 1 provided in the water pipe substrate 16a, respectively.
9, 19', 20, 20', the water purification cartridge 2 is connected to the valve part 1.
It is attached to the valve part 11 via a tightening ring 22a by a case 22 that fits into the receiving cylinder 21 of the valve 1 and engages with the outer periphery in that state. This cartridge 2 is filled with a cylindrical filter 2b made of carbon fiber wound with a non-woven fabric and surrounded by a synthetic resin net, with a hollow space 2c on the outside. Granular activated carbon may be charged into the space 2c.
Purified water flows from the gap 24 between the tip nozzle 22a of the case 22 and the water pipe 16 to the foam tap 25 of the faucet 10. In each figure, 26 is a seal ring;
27 is a tightening ring that connects the faucet 10 and the case 22, and 28 is a connector cap of the mounting member 8.

The water purifier of the present invention configured as described above determines the life span of the water purification cartridge 2 that is expected to be safe under the most severe expected usage conditions, and provides explanations such as estimating the amount of filtered water based on the number of family members, etc. based on that life. It is used as follows. Therefore, at the beginning of use, match the month number to index 6, and know the replacement time by the number corresponding to the number of months instructed by the explanation.

Since the present invention is constructed and operates as described above, the time to replace the water purification cartridge 2 can be displayed by matching the number 4 on the scale ring 5 with the indicator 6 on the indicator ring 7, so that the time for replacement can be clearly seen. The performance of the water purifier can always be properly demonstrated, and since the display section 3 is provided on the rear end surface of the water purifier main body 1, there is no possibility of accidentally touching the display section 3 while using the water purifier and causing the display to go awry. Settings are made by rotating one of the scale ring 5 and indicator ring 7, and the display can cover the entire rear end surface, making it very easy to handle and read.
