Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pot type water purifier which can be carried to a cafeteria or the like, instead of being fixed to a tap.

[0002]

2. Description of the Related Art In recent years, pot-type water purifiers have been manufactured and sold which are freely portable and can be taken from a kitchen to a dining table, a bedroom, an outdoor place, or the like. Unlike pot-type water purifiers, these pot-type water purifiers purify slowly and at a natural rate without applying extra water pressure.They are equipped with an ion exchanger and activated carbon as filter media, and use chlorine in water. It can remove odors, hardness components such as calcium and magnesium, and can remove trihalomethane, heavy metals and aluminum.

[0003] However, tap water may contain protozoa such as cryptosporidium, general bacteria, red rust, nigori components, and the like. In addition, when tap water is injected into a pot-type water purifier, tap water is used. Since it comes into contact with the atmosphere, various bacteria may be mixed. For this reason, there is a possibility that these germs may propagate while the purification is being performed over time.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a pot-type water purifier capable of preventing the propagation of various bacteria in view of the above-mentioned problems.

[0005]

In order to achieve the above object, the present invention is characterized by a pot type water purifier provided with a hollow fiber membrane.

Here, the hollow fiber membrane is preferably housed in a cylindrical case, and the case is preferably provided with a raw water receiving port made of an elastic material for directly connecting the case to a faucet.
Further, it is preferable that activated carbon is provided downstream of the hollow fiber membrane in the water flow direction.

[0007]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a schematic partial perspective view of a pot type water purifier showing one embodiment of the present invention, and FIG. 2 is a longitudinal sectional view of a filter cartridge portion provided in the water purifier shown in FIG.

As shown in FIG. 1, the water purifier of the present invention comprises a hollow fiber membrane in a water collecting tank 1 having a water outlet 2 for discharging purified water, a handle 3, and an openable / closable lid 4. A filter cartridge 7 having a filter medium such as 10 is provided.

The lid 4 is provided with an annular hole having a step, so that the filter cartridge 7 can be inserted and fitted from above.

As shown in FIG. 2, the filter cartridge 7 has a plurality of hollow fiber membranes 10 aligned in one direction and
A hollow fiber membrane module that is bent into a letter shape and housed and adhered and fixed in a cylindrical case 6 so that the membrane end opens downward, and a raw water receiving port that can directly connect a faucet provided above the case 6 12 and the like.

The raw water receiving port 12 is formed of an elastic body having a sealing property to the extent that inflow water does not leak, so that a pot type water purifier is directly connected to the faucet when water purification is required, and the raw water is supplied using tap water pressure. It can be supplied to the hollow fiber membrane 10 and filtered. Further, since the pot type water purifier can be directly connected to the faucet and the tap water can be supplied to the hollow fiber membrane 10 without coming into contact with the atmosphere, it is possible to prevent contamination of various bacteria floating in the atmosphere. Bacteria can be prevented from propagating inside. As the elastic body, nitrile rubber, silicon rubber, or the like, which is excellent in adhesion, elasticity, chemical resistance and the like, is preferable.

Further, it is preferable to provide an activated carbon 8 for removing chlorine on the downstream side of the hollow fiber membrane module in the water flow direction. Since the effect of the activated carbon 8 increases as the contact time with water increases, it is preferable that the activated carbon 8 is provided below the hollow fiber membrane 10 and is immersed in the water stored in the water collecting tank 1. Therefore, the activated carbon 8 is wrapped in a non-woven fabric or the like and stored in the case 6, and the portion of the case 6 where the activated carbon 8 is stored is provided with a water passage hole 13 so as to have water permeability not only on the end surface but also on the entire outer peripheral surface. Provide. It is also preferable to provide an ion exchanger for removing hardness components such as calcium and magnesium, and calcium sulfite for removing trihalomethane, heavy metals and aluminum, as the filter medium.

Next, a method of using the pot type water purifier will be described.

[0015] The pot type water purifier stores tap water from a tap faucet, and can be carried from a kitchen to a favorite place such as a dining table, a bedroom, or the outdoors, and can be left until needed. Is supplied to the pot type water purifier, the raw water receiving port 12 is connected to the snake. Raw water inlet 1
Raw water flowing in from the hollow fiber membrane 1 using tap water pressure
Filtered at 0. According to the hollow fiber membrane 10, even if tap water contains protozoa such as bacteria, cysts, and cryptosporidium, it can be removed together with red rust, nigori components, and the like.

The filtered water obtained by the hollow fiber membrane 10 is
Then, through activated carbon 8, water collecting tank 1 until used
Will be stored. Here, when a predetermined amount of water is stored in the water collecting tank 1, the activated carbon 8 is immersed in the water. However, the pot-type water purifier of the present invention stores a certain amount of water, and can be used from the kitchen to dining tables, bedrooms, and outdoors. For example, the contact time between water and the activated carbon 8 can be increased because it can be carried to a favorite place and left until needed. As a result, it is possible to obtain purified water having a very high chlorine removing effect.

[0017]

Since the water purifier of the present invention is a pot type, it is not necessary to constantly connect to the faucet, so that it can be widely used around the faucet. Can be carried anywhere you like, such as dining tables, bedrooms, and outdoors. And since it is provided with a hollow fiber membrane, it is possible to obtain purified water from which red rust, nigori components and the like have been removed when necessary, despite being free to carry. Also,
Even if tap water contains protozoa such as bacteria, cysts, and cryptosporidium, it can be removed together with red rust and nigori components.

Then, the hollow fiber membrane is housed in a cylindrical case, and the case is provided with a raw water receiving port formed of an elastic body for directly connecting the case to the faucet. The raw water can be supplied to the hollow fiber membrane using tap water pressure and filtered. Also,
Since tap water can be supplied to the hollow fiber membrane without coming into contact with the atmosphere, it is possible to prevent contamination of bacteria floating in the atmosphere and to prevent bacteria from growing in the filter medium.

Further, by providing activated carbon downstream of the hollow fiber membrane in the water flow direction, chlorine can be removed.
