Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purifier for home or business use, which is attached to a tap of a water supply.
The present invention relates to an improvement of a water purifier of a type that supplies purified water by passing tap water through a filter device section.

[0002]

2. Description of the Related Art Conventionally, water purifiers have been used for household and commercial purposes as a measure against the deterioration of the quality of tap water, but in recent years the demand has increased especially due to the use of water storage tanks in apartment houses and the like. Therefore, a water purifier of a type that is attached to a faucet for passing tap water through a filter device is often used after being attached to a faucet in a kitchen because of its ease of attachment.

Conventionally, this type of water purifier introduces water from a tap of a tap into a filter device section filled with an adsorbent such as a powdery material, a granular material, or a fibrous material to adsorb impurities and odorous particles. It has a mechanism to remove and purify it, and when it is used for drinking water, it is passed through the filter device section to be purified and used, and in the case of dishwashing etc., the water channel is changed to change the filter device section. The tap water is used as it is without flowing through.

That is, when the tap is attached to a tap and the tap of the tap is opened, the direction of the flow of water is changed by the water dip provided in the water purifier to the side of the filter device for water purification and the flow for normal water flow. I was switching to the exit side. When using purified water, this water purifier is one in which tap water is introduced into the filter device portion by a water dip and only water that has completely passed through the filter device portion is supplied from the purified water supply port.

Therefore, when purified water is not required as in the case of washing dishes, the water passage of the water faucet is switched to the side for directly discharging tap water so that the water does not pass through the filter device section. ing. When stopping tap water, the faucet valve is closed to stop the water.

[0006]

However, in the above water purifier, when the valve is closed to stop the water supply, or
When normal tap water is discharged as raw water by switching the water tap, the tap water previously introduced into the above filter device remains full of water. Water always stays in the filter unit and the water in the filter unit remains in the water purifier. Further, if the water was stopped by the water dip plug, the water retained in the filter device drips down and leaks around the periphery with water drops, which makes it unsightly.

Therefore, according to the conventional water purifier, even if the valve is closed, the accumulated water slightly drops due to its own weight from the purified water supply port of the filter device portion, which may cause a water leak at midnight. You may hear the sound of water drops dripping, and if you leave the accumulated water in the filter unit for a long trip, various bacteria may grow, and you may switch the water divider without closing the valve. Even when tap water is allowed to flow down as it is, there is a problem that the accumulated water in the water purification device always drips from the water purification inlet.

The present invention has been made in view of the above conventional problems, and tap water accumulated in a filter device portion of a water purifier can be easily discharged in association with a daily simple operation, It is an object of the present invention to provide a water purifier in which water droplets do not drop from the water purification supply port of the filter device section.

[0009]

To achieve the above object, the present invention relates to a water purifier which is attached to a tap of a tap and supplies the purified water by passing the tap water through a filter device section. The flow channel that allows the water to flow from the faucet as it is and the introduction channel that introduces tap water to the filter device side are formed so that they can be switched, and the tap channel is introduced when the tap channel is opened to allow tap water to flow. The water purifier is characterized in that the residual water in the inside of the filter device is made to be able to be discharged together with the flow-down water by allowing the residual water inside to flow into the vicinity of the flow-down water channel.

[0010]

Therefore, in the water purifier of the present invention, the flowing water channel for flowing the tap water from the faucet as it is and the introducing water channel for introducing the tap water to the filter device side are switchable, so that the water purifier can be switched. Sometimes tap water introduced into the filter device is purified and supplied from the purified water supply port.

Further, when the tap water is flowed by switching the water channels to the side where the tap water flows through the flow channel as it is, the tap water is directly discharged from the flow channel, and the introduction channel is provided in the vicinity of the flow channel. Since it is connected to the residual water inside, the water flow of the spilling water attracts the residual water in the introduction channel and discharges it downward together with the spilling water.

At this time, since the introduction water passage communicates with the filter device part, the residual water flows out, thereby exerting an ejecting action of continuously sucking and discharging the accumulated water of the filter device part together with the ordinary tap water. .. Therefore, the accumulated water in the filter device portion is discharged together with the normal flow of tap water, and the accumulated water in the filter device portion is reduced to prevent water leakage from the water supply port and dropping of water droplets.
