There are two types of built-in types: one that operates water stopping / discharging water mechanically and one that operates water stopping / discharging water via an electromagnetic valve. Some solenoid valve specifications use a latch-type solenoid valve in consideration of easy workability, and operate with battery power supply.
[0003]
[Problems to be solved by the invention]
However, the performance of the filter medium decreases every time it is used even if the initial removal capacity is high. Although components such as turbidity are currently removed with a filter medium such as a hollow fiber membrane, there is an increasing need for removing harmful substances for the purpose of current water purifiers. With the conventional water purifier type that measures the instantaneous flow rate as a criterion for filter medium replacement, it is difficult to measure the limit water volume of the filter medium, that is, the total water flow rate. Control parts other than operation switches and batteries are placed under the kitchen for the purpose of increasing the volume by securing space and for waterproofing from the top of the kitchen due to water purification and other faucets. This battery must be replaced every six months to one year. When replacing the battery, it is necessary to remove and replace the contents under the kitchen. It was difficult to say that the customer had to be satisfied and the customer was satisfied.

Embodiments of the present invention will be described below with reference to the drawings.
[0013]
FIG. 6 is a diagram showing an example of installation of a built-in water purifier in a kitchen according to an embodiment of the present invention, as viewed from the front. Water stoppage and water discharge are controlled by a latch electromagnetic valve 2 branched from a cheese 1 branched from a normal water tap. The tap water supplied by the latch-type solenoid valve 2 becomes turbid with activated carbon, hollow fiber membranes, etc. from the water supply hose 3, passes through the water purifier 4 equipped with a filter medium to remove free residual chlorine or harmful substances, and the connecting pipe 5 and Water is discharged from a water discharge pipe 8 for discharging purified water through a connecting pipe 6 installed in the faucet body 7. The faucet body 7 can be fixed on the kitchen with a nut 11. Moreover, the said water purifier main body 4 is built in under a kitchen, and only the component of the said faucet main body 7 appears on the kitchen upper surface part. The latch type solenoid valve 2 is driven by a dry cell operation. The dry battery is disposed in the faucet body 7, and a battery case 9 capable of replacing the battery is disposed in the faucet body 7. The faucet body 7 includes control function members such as a flow rate sensor and an operation board. The battery case 9 has a battery take-out direction on the faucet front side. Depending on the specifications of the kitchen, a wall may be arranged in the horizontal direction or at the rear side, and when taking out is installed on the upper surface of the faucet body, it is preferable to arrange it on the front side because splash water tends to contact the battery terminal . Reference numeral 10 denotes a power cord, which is a cord for transmitting information obtained by using the water purifier to the solenoid valve.
[0014]
FIG. 7 is a diagram showing an example of installation of a built-in water purifier in a kitchen according to an embodiment of the present invention from the top. The faucet body 7 has an operation panel 12 for clean water discharge on the upper surface of the kitchen, and the operation panel 12 is firmly sealed with glue or the like, so that there is no fear of water leaking from this section into the control section. In addition, as shown in the figure, it can be seen at a glance that the faucet is easier to use when the operation unit is installed on the front side.
[0015]
The detail of a faucet part is demonstrated in the built-in water purifier comprised as mentioned above.
[0016]
FIG. 1 is a cross-sectional view of a faucet body of a built-in water purifier according to an embodiment of the present invention, in which 21 is a lower casing, 22 is an upper casing, and is completely sealed by an O-ring 23 or the like. A battery housing case 24 accommodates a predetermined number of batteries 25 (in the present embodiment, four AAA batteries) and is divided into an opening side and a bag side. On the bag side, the required number of battery contacts 30 for connecting voltages in series (in this embodiment, four positive contacts and four negative contacts alternately) are stored, and a fixing and detaching button 26 is provided below the battery housing case 24. A biasing body 27 for always fixing is incorporated. The battery housing case 24 needs to be taken out of the battery 25, and the bag side end portion is arranged so that the packing 28 is completely sealed with the lower casing 21 in the housing hole portion and the outer shell portion according to the shape of the battery. It is structured around. The shape of the packing 28 will be described later with reference to FIG. 32 is a faucet connecting pipe through which a purified water is discharged from a water discharge pipe 34 through a flow rate sensor 33 and the like.
[0017]
The battery configuration is determined by the latched solenoid valve, the current consumption of the control unit, and the standby current. Normally, a plurality of dry batteries are used, but this embodiment will be described with the 6V specification. This is the case where the battery capacity is compared with the consumption of all the solenoid valves and the control unit and the standby current, and the battery is replaced after about one year. The 6V specification is about 4 batteries. A battery contact 30 is incorporated in the lower casing 21 via the terminal block 41 and supplies necessary power to the control board 31.
[0018]
FIG. 2 is an unlocked sectional view of the battery housing case of the built-in water purifier according to the embodiment of the present invention. When the button 26 is pressed, a claw lock 261 of the button 26 is provided at the lower part of the lower casing 211. The mechanism is released from the locking portion 212 and reaches the position of 262 to release. At this time, the removal direction of the battery 25 and the reaction force direction of the battery terminals 29 and 30 are the same. That is, when the lock is released after the button 26 is operated, the negative terminal of the battery terminal 29 has a spring characteristic, and in the case of an AAA battery, an urging force of about 5 N to 10 N is given per battery. This is because when the biasing force of the battery contact is too strong, a large amount of force is required at the time of re-storing, and when it is too small, the contact resistance between the battery terminals 29 and 30 and the battery 25 may increase and an appropriate power supply may not be obtained. This is because it is assumed. This is consistent with the battery industry recommended load. Further, the contact terminal can be made to have a plate thickness of 0.2 to 0.3 mm by applying nickel plating or the like to SUS304CSP having a spring property and low corrosiveness to obtain a reaction force. This spring characteristic is determined by setting a load that overcomes the packing 28 attached to the battery housing case 24, which will be described later, so that the battery housing case 24 moves forward when the lock is released. It is clear that it has been lifted. This is an important relationship with the above-described seal tightening margin of the battery packing. When re-accommodating the battery 25, a locking spring 27 is formed between the button 26 and the battery accommodating case 24, and the battery accommodating case 24 is locked by the bias of the spring when it reaches the specified position.
[0019]
FIG. 3 is a cross-sectional view around the battery of the built-in water purifier in one embodiment of the present invention, and shows details of the battery arrangement, the shape of the packing, and the fitting of the battery case. Although 2 verticals × 2 horizontals, 1 vertical × 4 horizontals, etc. are conceivable, in order to suppress the overall height, this embodiment has a shape of 1 vertical × 4 horizontals. In this case, it is desirable that the outer shell 241 and the lower casing 211 of the battery case are in an offset state as the packing shape. In addition, it is better to design the straight part on the ellipse side of the track shape in an R shape. This makes the packing 28 smaller than the battery case 241 and gives tension. In this case, the tension is different between the linear portion and the R-shaped portion, and the ellipse side is prevented from being easily turned over when the battery is stored. In addition, it is necessary to consider the insertion / extraction force, which can be used for facilitating removal by utilizing the reaction force of the battery terminal when removing the battery. Usually, 20 to 25% is required for tightening, but in this case, it may be too hard to cause difficulty in fixing the battery. By reducing the tightening margin to about 5 to 10%, it is possible to make the take-out force of the battery housing case 241 smaller than the sum of the negative side terminal reaction forces of the battery terminals 29 and 30 shown in FIG. Since only a reduction in the tightening allowance may cause doubt in the sealing performance, it is better to improve safety with a double bead or the like. Further, a method of improving slidability with grease or the like may be used.
[0020]
It should be noted that raising the center as an R shape also has an effect on drainage measures at the upper part of the battery case, which will be described later.
[0021]
FIG. 4 is a cross-sectional view of the faucet body side from which the battery of the built-in water purifier according to the embodiment of the present invention is removed, and shows a state where the battery housing case 24 is removed. In this case, the battery terminal 29 on the faucet body side is exposed to the outside, but the control board 31 is housed in the upper casing 22 at the upper portion, and water from the upper portion is avoided. Moreover, since the battery terminal 29 on the faucet body side is disposed at a position where the lower casing 21 is recessed, there is no direct water exposure. Further, since the terminal block 41 fixing the battery terminal 29 is in a fitting relationship with the lower casing 21, there is no water immersion on the control board side. In the completed state of the faucet configured as described above, the structure of the faucet outer shell is completely sealed except for the water purification outlet 42 of the water discharge pipe 34 during normal use in FIG. In addition, no water droplets are applied to the battery housing case 24, the battery contacts 29, 30 and the control board 31. Even when the battery housing case 24 in the figure is attached / detached (battery replacement state), the battery 25 is removed, so that actual water passage is not performed and there is no fear of getting wet.
[0022]
FIG. 5 is a perspective view of the battery housing case from which the battery of the built-in water purifier according to the embodiment of the present invention is removed. The battery 25 is housed inside, but the battery 25 itself houses the battery about 10 mm to 20 mm. Projecting from the case 24. This is because the manufacturer's battery display is described below the above dimensions (about 10 mm or less for each electrode) and it is easier to check with the engraved part of the battery housing case 24, and it is faster than taking out each battery one by one. A plurality can be taken out. The battery projecting dimension is desirably 10 mm or more that can be grasped by a finger, and more than half that is difficult to fall by its own weight is desirably accommodated in the battery accommodating case 24, and is 20 mm or less.
[0023]
In addition, since the battery housing case 24 is formed in a bag shape to avoid water exposure, it is assumed that moisture adheres to the top surface side. Actually, it is housed inside, so there is almost no influence, but it is desirable to have further consideration. In this figure, the positional relationship of the top surface where water droplets remain on the upper surface is always set so that A and C are lower than the other B, D, E, and F. As a result, the accumulated water reaches from the high position to the low positions A and C as indicated by the arrows, and is dripped from the packing 28 and does not adhere to the battery 25 (note that the double bead shape described above is used). Also see this figure).
[0024]
Note that drainage may be provided on the front side.
[0025]
Next, the case where a battery case is installed in the lower part of a control part is demonstrated in detail. As shown in FIGS. 1 and 4, the operation unit 35 must have an operation button and a display unit in a place where the arm extends from the convenience and enters the field of view. However, it is necessary to consider waterproofing because it is a watering device called a kitchen, and the position where the battery 25 is stored occupies a very important factor. There is no problem because there are no moving parts when the power source is an AC power source for general households, but if it is a dry cell type that prioritizes unnecessary workability of electrical work, control of clean water discharge and water stoppage The battery capacity is limited even when it is used with a latch-type solenoid valve, and eventually it will be necessary to replace the battery. In this case, the battery housing case 24 must be removed from the faucet body for replacing the battery 25. At that time, it is desirable to consider that the battery contact is exposed and moisture does not adhere to the contact, and when the battery is removed as shown in FIG. It is the best place.
[0026]
Although it has been explained that the battery housing case is optimally arranged in the lower part of the control unit from the viewpoint of preventing moisture adhesion to the contact point at the time of battery replacement, it is described with respect to the direction of removal. There are a wide variety of kitchens and manufacturers. The kitchen can not be selected for the convenience of the water purifier, and it must be structured to be attached to any kitchen. As shown in FIG. 7, depending on the type of kitchen, there are cases where there is a wall on the back surface A, and there are cases where the necessary space for battery replacement is restricted by walls, storage compartments, etc. The only place where the existing battery-replaceable space can be secured is the front side facing the sink and the top side facing the ceiling. However, when installed on the top surface side, the battery contacts also look like the top surface, and when moisture adheres, the gravity is applied evenly and moisture movement is difficult. When the front side of the sink shown in FIG. 7 is placed, the battery contacts will be in the vertical direction, and even if there is water on the battery contact side due to some sort of splash, it will flow downward according to gravity and water drops will fall on the sink. It goes without saying that it is a more efficient arrangement because it reaches the drain. Further, it is necessary to provide a shape that makes it difficult for moisture to adhere to the battery part even in a normal use state, and FIG. 3 shows a fitting relationship between the battery case 241 and the lower casing 211. If the volume is increased, it is conceivable to surround the battery housing. However, when the space is used effectively, even the thickness of the resin becomes a problem. In this case, as shown in FIG. 3, both the battery case 241 and the lower casing 211 in a fitting relationship must be exposed to the outside, and the battery case 241 must be slid. In this case, it is desirable to fit and fit the battery in a fixed position, and the water intrusion route is more inside when the fitting on the side that exposes the mating positional relationship to the outside is always installed at the bottom. It is clear that moisture is unlikely to enter because it opposes gravity (see the detailed view of FIG. 3).
[0027]
【The invention's effect】
Thus, the built-in type water purifier of the present invention is equipped with a latch-type solenoid valve, and when driving the battery, when replacing the battery for the customer, taking out the contents inside the kitchen, recontainment etc. In addition to reducing workability and physical distress during diving, it is possible to provide a water purifier that can be securely attached to any kitchen, can be easily replaced with a battery, and has improved waterproofness.
