On the other hand, as shown in Fig. 4, in the water purifier body 2, the battery case % accommodating the battery such as the button battery is placed on the waterproof case = 3G_reverse side via the raw water passage path 31. The battery case 52 is disposed on the rear side of the water purifier body 2, and has a body 53' which can be mounted (4) to the case body 54 which is engaged with the shallow bottom and has a substantially bottomed cylindrical shape. Further, the button battery is built in the battery case 52 in a state in which the diameter direction is in the up and down direction. In this manner, the thickness direction of the button battery can be suppressed in the front-rear direction of the water purifier body 2 in the longitudinal direction of the water purifier 1 as compared with the case where the thickness direction of the button battery is along the vertical direction. Further, the wire harness 44 which is taken out from the waterproof case portion 3A and is disposed by the raw water passing under the path 31 is connected to the battery case%. Further, although an example in which the wire harness 44 is disposed by the raw water passing through the path 31 is described, the route of the wire harness 44 is not limited to the above, and may be disposed in the raw water passage path 31 as long as the raw water passes through the idle space around the path 31. Above. Therefore, the water purifier 1 of the present embodiment is integrally formed with a display unit 22 that displays information on the timing of replacement of the filter cartridge 3, a flow rate detecting unit 23 that detects the flow rate of the raw water, and the raw water passing between the inflow port 4 and the filter cartridge 3 By the path 31', the number of components can be reduced and the waterproof structure of the display unit 22 and the flow rate detecting unit 23 can be unified as compared with the individual setting display unit 22, the flow rate detecting unit 23, and the raw water passage path 31. Information relating to the timing of replacement of the filter cartridge 3 is displayed, and miniaturization is achieved, and an increase in the number of steps of the water purifier can be suppressed. Further, the display portion 22 and the flow rate detecting portion 23 can be improved in water repellency, airtightness, and anti-condensation property. Further, since the impeller 24 is disposed in the raw water passage path 31 by integrally providing the flow rate detecting portion 23 and the raw water passage path 201135192 r 31, the relative position of the rotation detecting portion 25 and the impeller 24 that detects the rotation of the impeller 24 does not always change. Therefore, variation in the detected value due to a change in the relative position between the impeller 24 and the rotation detecting portion 25 can be suppressed, and the reliability of the flow rate detection can be improved. Further, the liquid crystal covering portion 5 is disposed opposite to the upper surface by soldering, whereby it is assumed that even if the soldering is poor, the water immersion caused by the upper water spray can be prevented; and the wire harness 44 is taken out from the downward drawing portion 46, It is assumed that even if the water-repellent treatment of the extraction portion 46 is insufficient, it is possible to prevent the water from being drawn into the waterproof casing portion 30' from the extraction portion 46 due to the water spray on the upper side, so that the waterproof reliability can be improved. Further, it is possible to ensure that the watertightness of the waterproof case portion 30 is sufficient without filling the waterproof case portion 3 with an insulating resin such as a potting material, and therefore, the assembly can be reduced as compared with the case where the potting material is filled in the waterproof case portion 30. The burden on the operator. Further, the wire harness 44 is fixed to the extraction portion 46 in the inserted state by the rubber gasket 47, and the liquid sealing material 48 is filled in the fixed state, whereby the sealing material is filled in a state where the wire harness 44 is not fixed. Compared with 48, the waterproof treatment can be easily performed. Further, since the waterproof structure is double-structured by the rubber gasket 47 and the filled liquid sealing material 48, the watertightness can be further improved. Further, the waterproof case portion 3A and the battery case 52 are disposed opposite to each other via the raw water passage path 31, whereby the wire harness 44 can be easily disposed with a short distance and the raw water can be effectively used in the space below the path 31. Since the harness is used to correct the space for sighing, it is possible to achieve miniaturization as compared with the case where the wiring harness 44 is additionally disposed. In this case, if the waterproof casing portion side and the battery case 52 side are arranged such that the wire harness 44 is drawn downward, the water resistance of 201135192 is improved, so that it is preferable that the pair of β The raw water of 4 is subjected to the contact of the blades of the impeller 24, so that the flow rate can be stably measured. In addition, since the opening portion 15 which can be easily observed between the inflow port 4 and the filter cartridge 3 can confirm the inside of the liquid crystal display unit displayed on the display unit 22, the commercial property can be improved. Further, the present invention of the water purifier is not limited to the water purifier 1 of the above embodiment, and various design changes can be made without departing from the scope of the invention. ,. For example, although the case where the display control substrate 21 and the sensor substrate 26 are arranged substantially in parallel has been described, the arrangement of the sensor substrate 26 may be appropriately changed without being limited to being substantially parallel. For example, even when the position of the raw water passage path 31 with respect to the waterproof case portion 3 is changed to the side wall side of the waterproof case portion 30 or the like for the water purifier corresponding to various designs, the sensor substrate 26 can be changed. The position, for example, the sensor substrate 26 is disposed perpendicular to the display control substrate 21, thereby flexibly corresponding to the water purifier of various designs. Further, although the display control substrate 21 and the sensor substrate 26 are separately provided in the water purifier 1 of the above-described embodiment, the display control substrate 21 and the sensor substrate 26 may be integrally formed to further reduce the size. . In the water purifier 1 of the above-described embodiment, the battery case 52 is disposed on the opposite side of the waterproof case portion 30 via the raw water passage path. However, as shown in FIG. 5, the battery case 52 may be used. It is disposed in contact with the side wall of the waterproof case portion 30, and an opening is formed in the wall portion between the waterproof case portion 30 and the battery case 52, and the display control substrate .21 and the sensor substrate 26 17 201135192 r are connected to the battery case by wiring or the like. 52 connections. This corresponds to an embodiment of the invention (9). The important part of the example is shown in Fig. 5, and the same reference numerals as in Fig. 3 denote the same meaning as Fig. 3. The present invention further provides a display unit for use in a water purifier which filters a raw water which is to be purified water to produce purified water, and displays information relating to the timing of replacement of the filter cartridge. The display unit is integrally formed with a passage path of raw water or purified water, a flow rate detecting unit that detects a flow rate of water passing through the passage, and a display unit that displays information related to the filter cartridge replacement timing based on the detection result of the flow rate detecting unit. . This is the item (1) of the present invention. This real form is the same as that shown in Figs. 6 and 7.
