However, the technique described in Patent Document 1 has a problem that the reverse osmosis membrane is easily clogged because the raw water is directly flowed into the reverse osmosis membrane without being filtered by a filter or the like.

In addition, if you want to obtain drinking water that does not have a salty odor from tap water, or if you do not get tap water but you can secure a power source, you can only operate manually and not automatically. However, there is a problem that it is inconvenient because the usage pattern is only manual operation.

Moreover, since the technique described in Patent Document 2 uses a motor as the pressurizing means, there is a problem that it cannot be used in a place where a power source cannot be secured. Therefore, there is usually power supply equipment, but when the power supply equipment is destroyed due to a disaster, etc. and becomes unusable, or in areas where there is no water supply equipment and no power supply equipment, safe and secure drinking water is required. However, there was a problem that the water purification device could not be operated.

The present invention was devised in view of these problems, and as a usage environment, either tap water can be used and power can be used, tap water cannot be used and power can be used, and both tap water and power can be used. It is an object of the present invention to provide a water purifier that can be used in any case and can obtain safe and secure drinking water.

Has the effect of preventing backflow.

  Next, the manual cylinder 14 will be described. It has a piston that reciprocates as a component and a handle 18 that reciprocates the piston. The size of the manual cylinder 14 is determined from the amount of raw water 40 delivered per reciprocation, the shift amount of the piston, etc. The amount of water per one reciprocation of the piston of the cylinder 14 is set to 60 cc, and the bore diameter of the piston is set to 32 mm.

Next, a hose or piping will be described. The inner diameter of the hose or pipe is made larger than the general inner diameter. For example, by installing a 3/8 inch hose or pipe where a 1/8 inch hose or pipe is usually attached, the pipe resistance in the hose or pipe can be greatly reduced, which makes it light and easy. The handle 18 can be pushed down.

Next, the pressure switch 10 will be described. As shown in FIG. 7A, the pressure switch 10 is turned on by the pressure of the raw water 40 flowing therethrough, and the pump is driven by this ON signal. For this reason, the pressure switch 10 is used when the raw water 40 flows without making an effort to draw water at the site of use like tap water. However, the pressure switch 10 cannot be used if the raw water 40 does not flow unless an effort is made at the site of use such as well water or bath water.

Next, the manual switch 11 will be described. As shown in FIG. 7B, the manual switch 11 constitutes a parallel circuit with the pressure switch 10, and is an alternative means when the pressure switch 10 cannot be used. When tap water cannot be used, well water or bath water is used. In this case, the manual switch 11 is used. When the manual switch 11 is turned on, the pump 12 is driven by this ON signal, and well water or bath water is drawn, and pressurized water is supplied to the water purification unit 3.

For the sediment filter 4, a filter having a pore diameter of 3 to 10 μm is used. For example, when a filter having a pore size of 5 μm is used, impurities such as dust and sand which are impurities of 5 μm or more contained in the raw water 40 are removed. Has an effect.

  Next, the precarbon filter 8 will be described. The pre-carbon filter 8 is disposed on the downstream side of the sediment filter 4, and the raw water filtered at the first stage by the sediment filter 4 is filtered at the second stage by the pre-carbon filter 8 having a finer pore size. A two-stage filtration structure is configured. By using a two-stage filtration structure, clogging of a filter having a small pore diameter can be suppressed. When the raw water 40 has almost no suspended solids in the raw water 40 like tap water, the pre-carbon filter 8 may not be provided.

  The pre-carbon filter 8 has a pore diameter of 0.5 to 2 μm. For example, when the pre-carbon filter 8 has a pore diameter of 1 μm, dust that is an impurity having a size of 1 μm or more contained in the raw water. It has the effect of removing impurities such as sand. The precarbon filter 8 uses activated carbon, and has an action of removing fine organic substances, inorganic substances, chlorine, odor, and the like by using the action of the activated carbon.

  Next, the reverse osmosis membrane water purifier 5 will be described. The reverse osmosis membrane water purifier 5 is disposed on the downstream side of the sediment filter 4 or on the downstream side of the precarbon filter 8 when the precarbon filter 8 is provided.

Separated into concentrated water containing. The reverse osmosis membrane has a pore size of 1 to 2 nanometers, and is a safe and secure permeate that allows only water molecules having a size smaller than the pore size to pass therethrough, and has a size larger than the pore size. Separated into concentrated water consisting of incapable substances. The permeated water can be made safe and secure drinking water.

  The concentrated water whose permeation has been blocked by the reverse osmosis membrane passes through a flow rate adjusting valve 7 for drainage provided in a hose or a pipe on the downstream side from which the concentrated water is discharged and is discharged to the outside and stored in the container 31. The Here, if the pressure on the discharge side of the concentrated water is low, the pressure applied to the raw water filling the upstream side of the reverse osmosis membrane in the reverse osmosis membrane water purifier 5 becomes lower than the osmotic pressure of the raw water. Since the substance of water in water cannot be permeated, in order to permeate the substance of water from the raw water, the flow rate adjusting valve 7 is throttled so that the pressure of the raw water is higher than the osmotic pressure of the raw water. Therefore, the pressure with respect to the raw water filling the upstream side of the reverse osmosis membrane in the reverse osmosis membrane water purifier 5 can be adjusted by adjusting the flow rate adjusting valve 7.

  Next, the post carbon filter 6 will be described. The post carbon filter 6 is disposed downstream of the permeated water sent out from the reverse osmosis membrane water purifier 5 and is mainly composed of activated carbon. The activated carbon contains permeated water containing a gaseous odor component as delicious water. Has the effect of
