Description

  The present invention relates to a water purifier installed in a sink such as a kitchen.

Water purification equipment that removes impurities in tap water with a water purification cartridge and provides the user with clean water (hereinafter referred to as water purification) is largely divided into a desktop type and built-in type, or a faucet integrated type depending on the installation form. Separated.
The desktop water purifier is installed on the top plate of the sink, and the installation method is to install a branch fitting on the main body of the existing faucet, and tap water derived from this branch fitting with a hose etc. Purified water is generated by a water purification cartridge, and the purified water is discharged from a water outlet provided in an existing faucet or water purifier via a branch fitting.
The built-in type water purifier uses a dedicated faucet that discharges only the purified water, and the water purifier is installed in the cabinet of the sink. A branch pipe is attached to the water supply pipe in the cabinet of the sink, and the branch pipe and the water purifier, and the water purifier and the dedicated water faucet are connected with a hose or the like. The built-in type is highly supported by users who seek a sense of unity with the sink and a refreshing feeling on the top plate (see Patent Document 1).
Further, the faucet integrated water purifier includes a small water purifier cartridge inside a water faucet of the faucet (see Patent Document 2). In this type, when the operation part of the faucet is operated, tap water passes through the small water purification cartridge and the purified water is discharged from the water outlet.

Although it is a water purification device that is rapidly spreading due to the demand for clean water, there are problems such as the work space of the kitchen being pressed by the installation of the water purification cartridge and the periodic replacement of the water purification cartridge is troublesome. is there. Even in the three modes described above, there are advantages and disadvantages in the installation and exchangeability of the water purification cartridge.
The desktop water purifier is provided with a water purifier on the top of the sink, so that the water purifier cartridge can be exchanged well. However, there is a problem that the water purifier occupies and presses the work space of the kitchen.
In the built-in type water purifier, since the water purifier is installed in the cabinet, the work space of the kitchen is secured, but the storage space in the cabinet is pressed. In particular, in a drawer-type cabinet that has become mainstream in recent years, there may be a case where the installation space for the water purifier cannot be secured. In addition, the water purification cartridge of the water purification device in the cabinet must be submerged in the cabinet at the time of replacement, and the exchangeability is poor.
The water faucet integrated water purification device contains a water purification cartridge inside the water discharge pipe, so it is easy to replace the water purification cartridge and does not compress the kitchen work space or the storage space in the cabinet. However, there is a problem that the service life (the ability to purify water) is short and the replacement frequency of the water purification cartridge is higher than that of the desktop type or the built-in type.
In addition to purifying water with a water purification cartridge, water reforming devices such as alkaline ion water generators that electrolyze water to produce alkaline ion water have the same problems as water purification devices. is there.

At this time, the container 45 is in a state where the valve body can be opened and water can be passed. Thereafter, the flow path unit 44 is rotated to the back side, the cover 53 is attached to the base case 52, and the replacement of the water purification cartridge 41 is completed.

In addition, although 1st embodiment demonstrated the example arrange | positioned in series with respect to the tap water which flows in from the inlet joint 42 about the water purification cartridge 41 using the different kind of purification agent 48, it is the same. In the case of using a kind of purifier, for example, the activated carbon cartridge 48b, in order to arrange the tap water flowing in from the inlet joint 42 in parallel, the flow path unit 44 shown in FIG. The channel 44c is formed so that the containers 45 are arranged in parallel, and the container 45 is connected to the connection port 44d of the channel unit 44. By doing so, the lifetime of each activated carbon cartridge B can be extended, the lifetime can be made uniform, and replacement can be completed at once.

Next, when it is desired to use alkaline water, the display unit having a desired pH concentration is selected with the mode switch 87a of the operation unit 72, and then the first operation unit 63 is operated in the direction of discharging water. The impurities in the tap water are removed by the water purification cartridge 41. The purified water generated thereby flows into the electrolysis unit 70.
In the electrolysis unit 70, alkaline water is generated by electrolyzing the purified water generated in the water purification unit 60 in the electrolytic tank unit 71, and alkaline water is discharged from the first spout 75 and acidic water is discharged from the second spout 77 as a by-product. Is done.

When it is desired to use acidic water, after selecting the acidic display portion with the mode switch 87a and operating the first operation portion 63 in the direction of discharging water, tap water flows into the water purification unit 60, and the water purification cartridge 41 is used. This removes impurities in the tap water. The purified water generated thereby flows into the electrolysis unit 70.
In the electrolysis unit 70, acid water is generated by electrolyzing the purified water generated in the water purification unit 60 in the electrolytic tank unit 71, and acidic water is discharged from the first spout 75 and alkaline water is discharged from the second spout 77 as a by-product. Is done.

Note that a flow rate sensor 89 is attached to the electrolysis unit 70 at an arbitrary position of the water purification pipe 38, and an integrated flow rate through which the purified water passes is calculated by this flow rate sensor. When the integrated flow rate reaches a preset flow rate, the replacement lamp 88 is turned on, and the user is notified of replacement of the water purification cartridge 41 by lighting.
The replacement method of the water purification cartridge 41 in the second embodiment is performed by the same method as in the first embodiment.
