出し浄水器内に滞留することがない。(Function) According to the water purifier of the present invention, a drain valve is provided inside the water purifier. When the water purifier is in use, the pressure inside the water purifier increases, so that pressure is applied to the diaphragm, which has a larger pressure receiving area than the pressure receiving area facing the water drainage passage of the valve member, which is installed on the side of the valve member that receives water pressure. As a result, the force acting on the valve member increases, and the valve member resists the urging force of the urging means through the diaphragm and reliably closes the drain passage, preventing tap water from leaking to the outside. It's becoming like that. When tap water is not used, the pressure inside the water purifier is low, so a predetermined water pressure is not applied to the pressure receiving part, and the valve member is separated from the water drain passage by the urging force of the urging means, and the water drain passage is opened. Therefore, the tap water inside the water purifier does not flow out from the water drain passage and stay inside the water purifier.
従つて、滞留した水道水中に雑菌が繁殖するこ

善され、また水道水が自動的に排出されるため使
い勝手が向上する。 Therefore, bacteria do not propagate in the accumulated tap water, and the water purifier is improved from a hygienic standpoint, and the tap water is automatically discharged, making it easier to use.

Further, the bottom wall 21a of the housing 20 is provided with a drain valve 40 according to the present invention. Detailed views of the drain valve 40 are shown in FIGS. 1 and 2. The drain valve 40 is attached to fit into a hole 42 formed at the bottom of the housing 20. The drain 40 has a convex portion 43 in the center and an upper portion 45 in which a recess 44 is formed. Also provided below the upper part 45 is a lower part 48 having a recess 47 which together with the recess 44 of the upper part 45 forms a chamber 46 . A valve 50 as a valve member is disposed within the chamber 46 and is biased downward by a spring 49 as biasing means.
A passage 53 and a discharge port 54 are connected to the interior of the water purifier through contact between the side surface 51 of the 0 and the sealing member 52 attached to the upper part 45.
It is becoming easier to communicate with and close them. and,
Since the spring 49 is biased downward, its biasing force moves the valve 50 away from the passage 53 to open the passage. The control of the valve 50 is performed by the movement of a diaphragm 55, which serves as a pressure receiving part and has a pressure receiving area larger than the pressure receiving area facing the passage 53 of the valve 50, which is fixed by a fixture 54a below the valve 50. . The diaphragm 55 divides the chamber 46 into an upper chamber 55a and a pressure receiving chamber 55b. A communication hole 56 communicating with the inside of the water purifier is provided in the pressure receiving chamber 55b.

5 rises due to water pressure. As the diaphragm 55 rises, the side surface 51 of the valve 50 comes into contact with the sealing member 52, and the passage 53 and the outlet 54 are cut off, and the water flowing inside the water purifier does not flow out to the outside (Fig. 2). reference). Further, a diaphragm 55 having a larger pressure receiving area than the pressure receiving area of the valve 50 facing the passage 53 on the side receiving the water pressure inside the water purifier of the valve 50.
Because of this provision, when the diaphragm 55 receives water pressure inside the water purifier, the force acting on the valve 50 increases and the valve is reliably closed. Therefore, even if there is a pressure fluctuation inside the water purifier, the valve 50 will not separate from the sealing member 52, and no water leakage will occur.

る。 During flushing, the valve member 32 is switched to the flushing position by rotating the switching lever 32a as shown in FIG. 4C. Then, the water passages 13, 13 constituting the cleaning water channel C are opened, the water flow resistance is reduced, and the water that has passed through the adsorbent layer 9 flows vigorously over the surface of the hollow membrane module 11 and is cleaned.

6, water pressure is transmitted to the pressure receiving chamber 55b,
The diaphragm 5 resists the biasing force of the spring 49.
5 rises due to water pressure. As the diaphragm 55 rises, the side surface 51 of the valve 50 comes into contact with the sealing member 52 and is blocked between the passage 53 and the discharge port 54.
The water flowing inside the water purifier A does not flow to the outside (see Figure 2).

参照）。 When the water purifier A is not in use, water does not flow into the water purifier A and no water pressure is generated. Therefore, pressure is not transmitted through the communication hole 56, and the valve 50
is urged downward by the spring 49, so the passage 53 and the discharge port 54 are in communication with each other, and the water that flows through the water purifier during filtration and flushing, and then drains the water remaining on the bottom wall 21a to the passage 5.
3. Discharge to the outside via the discharge port 54 (see Fig. 1).

き弁からの漏れが発生することはない。(Effects of the invention) According to the invention, tap water has an adsorbent layer that removes off-flavors and odors contained in tap water, and a membrane module that removes bacteria. A water purifier is equipped with a filtration system waterway that sequentially passes water through the water for filtration, and a water drain valve is provided inside the water purifier to prevent tap water from stagnation when not in use. a passage, a valve member for opening and closing the water drainage passage, a biasing means for separating the valve member from the water drainage passage and urging the valve member in a direction to open the water drainage passage, and a water pressure inside the water purifier of the valve member. a diaphragm which is a pressure receiving part attached to the receiving side, and the diaphragm communicates with the inside of the water purifier at a position opposite to the urging means to transmit the water pressure inside the water purifier, and the water pressure inside the water purifier is transmitted. A pressure receiving chamber is formed in which the valve member is moved in the valve closing direction against the urging force of the urging means, and the pressure receiving area of the diaphragm facing the pressure receiving chamber is reduced to the pressure receiving area of the diaphragm facing the water drainage passage. Since the area is larger than the pressure receiving area of the member, when the water purifier is not in use, the water pressure inside the water purifier will be low, and the prescribed water pressure will not be applied to the diaphragm, so the water drainage passage will be opened by the urging force of the urging means. The water that has accumulated inside the water purifier will be discharged to the outside. Therefore, it is possible to prevent water from remaining inside the water purifier while the water purifier is not in use, which is improved from a sanitary standpoint, and at the same time, the water is automatically discharged, thereby improving usability. In addition, a diaphragm with a pressure receiving area larger than the pressure receiving area of the valve member facing the water drainage passage is installed on the side of the valve member that receives water pressure inside the water purifier, so when the diaphragm receives water pressure inside the water purifier, , the force acting on the valve member increases. Therefore, even if there is a pressure fluctuation inside the water purifier when the water purifier is in use, the valve will not open due to the pressure fluctuation and will be reliably closed, and no leakage will occur from the drain valve.
