[Industrial applications]

 The present invention relates to a domestic water purifier that can be attached to a tap of a domestic water supply, and can purify bacteria, red rust, mold, etc. of tap water with a hollow fiber membrane filter to obtain tasty and sanitary water.

[0002]

[Prior Art]

 FIG. 20 shows the structure of a conventional household water purifier. The water purifier is used by being attached to the tap of a domestic water supply, and has the function of filtering tap water through a hollow fiber membrane filter, etc., which is installed inside, to make the water delicious and clean. In addition, there is a convenient mode in which the raw water of the tap water is directly output as it is without passing through these filters, or in the form of a shower, and these modes can be easily switched using the switching valve as needed. Therefore, the main structure of the water purifier is composed of the water purification mechanism and the water flow switching mechanism.

Tap water introduced from the faucet 20 reaches a switching valve 11 where the direction of flow can be switched. First of all, the mode that the raw water is flowed straight. FIG. 20 shows the state of this mode, in which water flows as shown by solid arrows. Next is a mode in which the raw water is made into a shower and poured. When the switching valve 11 is turned to change the flow path, it flows like a shower from a small number of small holes formed in the outlet as shown by the broken line arrow in FIG. When the switching valve 11 is further turned to change the flow path, the flow proceeds toward the water purifying mechanism as shown by the alternate long and short dash line arrow in FIG.

Here, the water flow switching mechanism will be described in more detail. Tap water introduced from the faucet first passes through the circular hole of the seal packing 12. The tip of the seal packing 12 is in contact with the outer periphery of the switching valve 11 to seal it. The switching valve 11 has a cylindrical shape as shown in FIG. 21, and has three flow path switching holes on its outer circumference. FIG. 22 is a horizontal cross-sectional view of the switching valve 11 as seen from above. The raw water straight hole 13 penetrates the switching valve 11 up and down to allow the raw water to flow directly to the plate. The raw water shower hole 14 and the purified water hole 15 are opened on the same outer circumference at positions shifted by a certain angle. The water that has entered from the raw water shower hole 14 flows to the right in the figure as indicated by the broken line arrow as the inside of the switching valve 11 is partitioned. As shown in FIG. 20, the water flowing to the right flows like a shower. In addition, the water that has entered from the water purification hole 15 in FIG. 22 flows to the left in the figure as indicated by the alternate long and short dash line arrow as the inside of the switching valve 11 is partitioned. As shown in FIG. 20, the water flowing to the left flows toward the water purification mechanism. The switching is performed by rotating the switching valve 11 with the knob 8, and as the valve 8 rotates, water flows only from the hole that abuts the circular hole of the seal packing 12. In FIG. 22, an O-ring 16 is fitted on the outer circumference of the switching valve 11 and is sealed so as not to flow into another flow path.

The water flowing to the water purification mechanism in FIG. 20 first passes through a filter 17 for removing rough dust and the like, and then a granular activated carbon 18 for removing odors, chlorine and organic substances, and a hollow fiber membrane filter 19 for bacteria and red rust. Clean water can be obtained by removing mold, etc. These filters and activated carbon will become clogged and lose their effectiveness as they are used, and will have a longer life, so they can be replaced with cartridges. Considering the life of the water purification mechanism in this way, it is a good practice to use purified water mainly for drinking water and simmered food, and to use raw water for washing etc. This is the reason why it has a mode that can use raw water.

Although the water purifier can be conveniently used as described above, there are problems. First of all, the amount of water is considerably reduced when a water purifier is installed compared to ordinary tap water. When passing through the water purification mechanism, it passes through activated carbon or a filter with a large flow resistance, so it can be said that it is unavoidable that the amount of water drops. However, even when raw water is used, the amount of water is reduced by passing through a flow path with a large resistance, which is narrowed by a switching valve 11 as shown in Fig. 20, and a large amount of water is once washed. When you want to use it, you have to say that it is difficult to use. In order to secure a large flow path, the size of the device itself becomes large, so the flow rate is unavoidably sacrificed.

Further, in the conventional water purifier, water can flow only in one direction even if it is said from the structure of the switching valve. By rotating the switching valve 11 with the knob 8, water can flow only from the hole in contact with the circular hole of the seal packing 12. Therefore, it cannot be used in multiple ways, for example, washing water while collecting purified water, which is also inconvenient.

[0008]

[Problems to be solved by the device]

 The problems to be solved are the following two points. First of all, I want a large amount of water when I wash clothes using raw water. Secure as much water as possible at this time. In addition, it should be possible to use it in multiple ways, for example, washing water while collecting purified water.

[0009]

[Means for Solving the Problems]

 The present invention intends to improve usability by improving the structure of the switching valve so that water can flow in a plurality of directions.

[0010]

EXAMPLE The example shown in FIG. 1 will be described. The water purifier body 1 has a sealed room 2 for receiving tap water, and a plurality of holes are formed in this lower partition wall to flow out water, that is, a raw water straight flow passage 3, a raw water shower flow passage 4 , A purified water flow path 5 is formed. Three valves 6 for opening and closing this are provided corresponding to each hole, and there are three cams 7 that rotate corresponding to each valve. These cams are connected by a shaft, and a knob is provided at the tip. 8 is attached, and the valve can be opened and closed by rotating it manually, and the flow direction can be switched to multiple directions.

The open / closed state of one valve will be described with reference to a side view. 2 shows a closed state, and FIG. 3 shows an open state. The valve 6 is made of a leaf spring material and is pre-biased in the opening direction. In FIG. 2, the valve 6 which is biased in the opening direction in advance is pressed by the circumferential portion of the cam 7 to close the hole, and the valve 6 is closed. In FIG. 3, the cam 7 is rotated to bring the notch 9 of the cam 7 into contact with the valve 6 to open the valve 6 which is biased in the opening direction in advance. The seal structure will be described with reference to FIG. 2. Needless to say, the hole has a packing 10 for reliable sealing, and the valve 6 that abuts this packing hole is formed in a hemispherical shape so as to prevent water leakage. FIG. 4 is a view of these parts viewed in a three-dimensional manner in a manner that is easy to understand and slightly separated. As shown in this figure, the valve 6 is made of an integral leaf spring, and if the valve portions at the tips are separated and moved independently, the number of parts is smaller than when three valves are mounted. As described above, there are three sets of valve mechanisms that are opened and closed by the rotary cam, and the modes can be sequentially switched by shifting the open position of the cam.

The states of the three valves for each mode will be described with reference to the drawings. First is the water purification mode. FIG. 5 shows the state of the water purifying valve, which is in the open state. Figure 6 shows the raw water straight valve closed. Figure 7 shows the raw water shower valve closed. Water flows from the above three valves into the purified water flow path. Therefore, it becomes the water purification mode. Next is the raw water straight mode. Fig. 8 shows the water purification valve closed. Figure 9 shows the raw water straight valve open. Fig. 10 shows the raw water shower valve closed. Water flows through the raw water straight flow path from the above three valve states. Therefore, it becomes the raw water straight mode. Next is the raw water shower mode. Fig. 11 shows the water purification valve closed. Figure 12 shows the raw water straight valve closed. Fig. 13 shows the open state with the raw water shower valve. Water flows from the above three valve states to the raw water shower passage. Therefore, it becomes the raw water shower mode.

The above is the three basic modes used in the conventional water purifier. With the flow path switching structure according to the present invention, a new mode is added by devising the notch position of the cam. Easy to do. Next, we will explain the new mode of raw water straight and raw water shower combined mode. Fig. 14 shows the water purification valve closed. Fig. 15 shows the raw water straight valve open. Figure 16 shows the raw water shower valve open. From the above three valve states, water can be made to flow through the two channels of the raw water straight flow passage and the raw water shower flow passage. If this mode is provided, it is possible to solve the problem, which was first pointed out for the water purifier, that the flow rate is low. By opening two flow paths at the same time, rather than increasing the size of the device itself, the flow rate can be almost doubled compared to the single mode flow rate of conventional water purifiers, and the flow rate at the time of emergency can be secured. .. If this mode is newly added to the basic 3 modes, it becomes 4 modes, but since the raw water straight channel cam and the raw water shower channel cam have two open states while switching all modes, As a matter of course, it has two cutouts 9 in two places.

Described next is the new full open mode. Figure 17 shows the water purification valve open. Fig. 18 shows the raw water straight valve open. Figure 19 shows the raw water shower valve open. From the above three valve states, water can be flowed to all of the raw water straight flow passage, the raw water shower flow passage, and the purified water flow passage. If this mode is used, the problem pointed out as the second problem of the water purifier, which cannot be used for multiple purposes such as washing water while collecting the purified water, can be solved. Furthermore, in this case, there is no change in that multiple uses can be achieved by opening the purified water flow path instead of opening all modes and opening either the raw water straight flow path or the raw water shower flow path. Since various modes can be considered, it is sufficient to start with the one with the strongest demand from the user.

[0015]

[Effect of the device]

 As explained above, the water purifier of the present invention solves the inconvenience and the small flow rate that can be used only in the single mode of the conventional water purifier, and the switching valve can be freely opened and closed to create multiple flow paths. Since it is possible to flush water at the same time, the convenience of securing a flow rate and using multiple modes at the same time has been obtained, thus improving ease of use.
