Description

Water Purifier

The invention relates to a water purifier. In particular, it relates to a water purifier used in an overall water purification system that supplies purified water to all locations in a home, which can prevent the clean water containing no chlorine component from staying in the branch pipe of the water pipe for a long time. Corrosion or the production of bacteria.

In the past, small water purifiers for the purpose of removing residual chlorine, musty, dirt, and microorganisms from tap water have been widely used. The filter material of such a water purifier is mainly composed of a residual chlorine, an odor, an odorous activated carbon, a ceramic filter, a fine filter for removing turbidity or microorganisms, a hollow fiber membrane, and the like.

When the water purifier is installed in a general household, it is connected to individual divergent pipes of the tap water outlet such as a faucet of a kitchen counter, a hot water spout of a bathroom water heater, and the like.

In addition, in recent years, the demand for the use of purified water has increased in all areas of the building. However, it is cumbersome to set the water purifiers in all the locations where the tap water is used. Therefore, install the water purifier on the main switch of the tap water facility or the secondary side of the water meter (water supply from the water meter to the water heater) Tube), according to the total use of tap water for household purification, and the purification of purified water to the overall construction of the overall water purification system is increasingly popular.

A water purifier for such an overall water purification system, which is internally provided with a filter cartridge filled with a filter material, which is necessary for replacement after each specific use period (for example, after every one year), but is filtered. When the cartridge is replaced, the replacement procedure is complicated, and the operation is required to be proficient. Therefore, it is extremely difficult for the operator and the user to perform the replacement of the filter cartridge on a daily basis.

For the purpose of such a problem, it is a simple and safe replacement operation of the filter cartridge. For example, in Patent Document 1 of the present applicant, a simple operation of rotating the handle attached to the filter cartridge is disclosed. The water purifier of the filter cartridge relative to the water purifier can be removed.

Specifically, as shown in FIG. 5, the main body 202 of the water purifier 201 includes a base member 205 and a cylindrical outer casing 207 which is fixedly and detachably attached to the inside of the base member 205 and has a filter (not shown).

It is also said that the water purifier can remove approximately 100% of the chlorine component contained in the tap water. Therefore, when the water purifier used in the overall water purification system disclosed in Patent Document 1 is provided, for example, if the individual hydrants at the ends of the household are not used for a long time, they are left in the water purifier. Even in the manifold of each hydrant, tap water containing almost no chlorine component will remain for a long time.

If such clean water containing almost no chlorine component stays in the manifold for a long time, the corrosion of the manifold may be deteriorated due to the propagation of the bacteria, especially in the summer, which may become unsanitary water, which is suspenseful. By.

The present invention has been developed in view of the above points, and relates to a water purifier used in an overall water purification system for supplying whole water in a household, which can suppress the clean water containing no chlorine component in the water pipe. Corrosion or miscellaneous bacteria caused by prolonged retention in the diverging piping.

In order to achieve the above object, a water purifier according to the present invention includes: a cylindrical outer casing; and a filter having a hollow portion from which clean water flows out, which can remove at least a part of the chlorine component of the tap water, and the outer casing and the outer casing The inner surface is formed in the outer casing at a specific interval; the base member has an inner bottom portion, and is formed with a fitting recess portion that can be fitted to one end of the outer casing; and a first communication passage that communicates with the inner bottom portion a first opening portion and an inflow pipe opening portion formed on a side surface of the base member to which an inflow pipe into which tap water flows is connected; a hollow filter support pipe having one end connected to the hollow portion of the filter and the other end connected a second opening formed on the inner bottom portion; a second communication path a second opening, an outflow pipe opening formed on a side surface of the base member, and a bypass passage connected to a side surface of the base member; and a bypass passage communicating with the third opening formed in the inner bottom portion and the first opening a communication path opening formed at a specific position of the communication path; and an opening adjustment mechanism that adjusts an opening area of the bypass path.

Here, the outer surface of the filter is disposed to form a specific gap with the inner surface of the cylindrical outer casing, whereby the tap water flowing into the outer casing flows into the filter through the gap, and can be contained in the tap water. Impurity filtration.

Further, the filter has a hollow portion from which the purified water flows, whereby the tap water (purified water) filtered by the filter can flow out to the outside of the water purifier through the hollow portion.

Further, the filter removes residual chlorine contained in the tap water by removing at least all of the chlorine component or a part thereof.

Further, by the base member having the inner bottom portion and the fitting recess portion which can be fitted by one end of the outer casing, the outer casing and the base member can be easily fixed and detached.

In addition, the tap water sent from the inflow pipe is provided by the first communication passage that connects the first opening formed in the inner bottom portion and the inflow pipe that is connected to the inflow pipe to which the tap water flows and is formed on the side surface of the base member. It is allowed to flow into the casing from the first opening through the first communication passage, and further purify the water through the filter.

Further, the hollow filter is provided by a hollow portion having one end connected to the hollow portion of the filter and the other end connected to the second opening portion formed on the inner bottom portion. The support tube can be fixed by attaching the hollow portion of the filter to one end of the filter support tube, that is, the filter can be fixed.

Further, the filter support tube is hollow, and the purified water flowing out from the hollow portion of the filter can flow out through the filter support tube to the second opening.

In addition, the second communication passage having the second opening and the outlet pipe connected to the side surface of the base member, which is connected to the outlet pipe through which the clean water flows, allows the purified water to pass through the second opening. The two communication paths flow out to the individual outflow pipes at the ends.

Further, by having a bypass passage that communicates with the third opening formed in the inner bottom portion and the communication passage opening formed at a specific position of the second communication passage, a part of the tap water containing the chlorine component can be prevented from passing through the filter. Flow out to the second communication path. Therefore, for example, even if there is a situation in which the individual hydrants at the end of the household are left unused for a long period of time, the purified water remaining in the outflow pipe contains a certain amount of chlorine component, and the growth of the bacteria can be suppressed, and the pipe is discharged. Corrosion deterioration prevents it from happening.

Further, by the opening degree adjustment mechanism having the opening area of the bypass passage, the amount of water flowing out of the tap water flowing out of the pipe can be adjusted, and the content ratio of the chlorine component of the purified water can be changed. Therefore, for example, when an individual hydrant at the end of the home is used at all times, the opening area can be minimized, and purified water containing almost no chlorine component can be utilized. On the other hand, in the case where the frequency of use of individual hydrants at the end of the home is small, the opening area can be increased, and the purified water contains a certain chlorine component, so that the water in the outflow pipe can be prevented from being cleaned for a long time. Corrosion of the outflow piping caused by the detention deteriorates Of course.

Further, in the case where the opening degree adjusting mechanism is constituted by a female screw portion formed on a side surface of the base member and a male screw portion that is screwed to the female screw portion and variably adjusts an opening area of the bypass passage at the distal end portion The opening area of the bypass passage can be easily changed in accordance with the movement of the male screw portion caused by the rotation of the male screw portion.

In addition, when the female screw portion is formed to be substantially perpendicular to the bypass passage, the amount of protrusion of the male screw portion to the bypass passage can be adjusted by visually observing the third opening portion, so that the workability is improved.

In addition, when the area of the opening of the bypass passage is set so that the residual chlorine concentration is approximately 0.1 mg/L or more, the minimum residual chlorine concentration in the purified water can be contained.

Further, when the inner bottom portion has a circular shape, and the first opening portion, the second opening portion, and the third opening portion are disposed on the diameter line of the inner bottom portion, the first communication passage and the second communication passage that communicate with each other can be configured. The configuration of the bypass passage is simplified, productivity can be improved, and the problem of the first communication path, the second communication path, and the clogging in the bypass path can be prevented.

In addition, when the first opening portion and the third opening portion are disposed at positions along the line symmetry with respect to the second diameter line substantially perpendicular to the first diameter line, the first communication path and the bypass path that communicate with each other can be provided. The configuration is more simplistic, and productivity can be improved, and it is possible to prevent problems such as clogging in the first communication path, the second communication path, and the bypass path.

The water purifier according to the present invention relates to a water purifier used in an overall water purification system for supplying purified water to all positions in a home, which can suppress the divergence of the clean water containing no chlorine component in the water pipe for a long time.

Fig. 5 is a view showing the prior art.

Hereinafter, embodiments of the present invention related to a water purifier will be described with reference to the drawings to understand the present invention. Moreover, in the drawings, for convenience of explanation, when the water purifier is set to a certain state, the direction from the base member toward the outer casing is defined as a vertical upward direction, and the opposite direction is defined as a vertical downward direction, and The vertical direction of the vertical direction is defined as the horizontal direction.

First, the overall structure of the water purifier 101 to which the present invention is applied will be applied. It is illustrated in Figure 1. The water purifier 101 is used for a water purifier of an overall water purification system installed on a secondary side of a tap water such as a front entrance or a front of a courtyard or a water meter.

As shown in FIG. 1, the water purifier 101 has a body 102 and a cover 103 covering the body 102. The outer cover 103 has a substantially cylindrical shape with a lower opening, and a grip portion 104 is provided at an upper portion of the outer cover 103. The user can fix and disengage the outer cover 103 by holding the grip portion 104 with the hand.

The body 102 of the water purifier 101 includes a base member 105 and a cylindrical outer casing 107 that is fixedly and detachably attached to the base member 105 and has a filter 106 therein. A handle 108 is detachably attached to the outer casing 107, and the user can hold the outer casing 107 by holding the handle 108 with the hand.

Here, the outer casing 107 does not have to be necessarily cylindrical. As long as the space in which the filter 106 can be disposed is formed inside, it may be a cylindrical shape such as an ellipse or a polygon.

Moreover, the outer casing 107 does not have to be attached to the handlebar 108. However, by having the handle 108, not only the handling of the outer casing 107 can be facilitated, but also the fixing of the outer casing 107 can be easily performed.

An inflow pipe 110 into which the tap water before the treatment flows in is connected to the side surface 109 of the base member 105. Further, on the side surface 109 of the base member 105, at the opposite position of the inflow pipe 110, an outflow pipe 111 for supplying the purified water passing through the filter 106 to the individual faucet is connected. Further, a fitting recess 112 for fitting the lower portion of the outer casing 107 to fix the outer casing 107 is formed in the upper portion of the base member 105.

A plurality of (for example, four) locking portions 113 are protruded from the outer peripheral surface of the lower portion of the outer casing 107, and an annular locking portion 114 is protruded from the inner circumferential surface of the fitting concave portion 112. A plurality of (for example, four) notch portions 115 are formed in the locked portion 114, and the notch portion 115 is set to a size through which the locking portion 113 can pass. After the outer casing 107 is inserted into the fitting recess 112, when the outer casing 107 is rotated with respect to the fitting recess 112, the locking portion 113 is locked to the engaged portion 114. Further, the water purifier 101 includes the lock plate member 116. When the lock plate member 116 is inserted into the notch portion 115 after the outer casing 107 is rotated, the outer casing 107 is fixed so as not to be rotatable.

As shown in FIGS. 2 and 3, the fitting recess 112 formed in the base member 105 has a circular inner bottom portion 117, and the central portion O of the inner bottom portion 117 is formed with a second opening portion 119. Further, on the inner bottom portion 117, the first opening portion 118 and the third opening portion 120 are formed at positions which are line symmetrical with respect to the second diameter line L2 orthogonal to the first diameter line L1.

Here, the inner bottom portion 117 of the fitting recess 112 does not necessarily have to be circular. For example, it may be formed in an elliptical shape or a polygonal shape.

Further, the central portion O of the inner bottom portion 117 does not necessarily have to form the second opening portion 119. The second opening portion 119 may be formed at a position eccentric from the center portion O. Since the filter support tube 122 that supports the filter 106 to be described later is connected to the second opening 119, the second opening 119 is preferably formed at the center portion for the purpose of stably arranging the filter 106 in the fitting recess 112. O.

Further, it is not necessary to form the first opening portion 118 and the third opening portion 120 in a line symmetry with respect to the second diameter line L2. Want. However, in the case where the first opening portion 118 and the third opening portion 120 are formed on the first diameter line L1, the first opening portion 118 and the third opening portion 120 are formed on the side surface 109 of the base member 105 from the opposite direction. Since the first opening portion 118 and the third opening portion 120 are disposed at positions where the inflow pipe 110 and the outflow pipe 111 are equal, the structures of the first communication passage 126 and the bypass passage 128, which will be described later, can be simplified and prevented. The bad situation such as clogging is not the case.

A hollow filter support tube 122 that is inserted into the hollow portion 121 of the filter 106 and supports the filter 106 in the outer casing is attached to the second opening 119.

The filter 106 is mainly composed of residual chlorine, odor, odorous activated carbon, ceramic filter, and a microfiltration membrane or a hollow fiber membrane capable of removing turbidity or microorganisms. The inner surface of the outer casing 107 is 123. An annular gap 125 for introducing tap water before purification is formed between the outer surface 124 of the filter 106 and the outer surface 124 of the filter 106.

A first communication path 126, a second communication path 127, and a bypass passage 128 are formed in the base member 105.

The first communication passage 126 is bent in the vertical direction from the inflow pipe opening portion 129 formed in the side surface 109 of the base member 105 and connected to the inflow pipe 110, and communicates with the fitting recess portion 112 through the first opening portion 118.

The second communication passage 127 is bent in the horizontal direction from the second opening portion 119 and communicates with the outflow pipe 111 through the outflow pipe opening portion 130 formed on the side surface 109 of the base member 105 .

The bypass passage 128 communicates with the second communication passage 127 through the communication passage opening portion 131 formed on the side surface 109 of the second communication passage 127 in the vertical downward direction from the third opening portion 120. In other words, the bypass passage 128 prevents the tap water flowing into the fitting recess 112 from the inflow pipe 110 from flowing into the filter 106 to cause the tap water to flow out to the second communication passage 127.

The side surface 109 of the base member 105 is provided with an opening degree adjustment mechanism 132 that can adjust the opening area of the bypass passage 128 at a position directly above the connection position of the outflow pipe 111.

The opening degree adjustment mechanism 132 is composed of a female screw portion 133 formed at a position directly above the base member 105 and a male screw portion 134 screwed to the female screw portion 133. The female screw portion 133 is formed to penetrate through the side surface 109 of the base member 105 and the bypass passage 128 so as to be substantially orthogonal to each other.

When the male screw portion 134 is screwed to the female screw portion 133, the male screw portion is rotated by a known tool such as a screwdriver or a hex wrench, and the front end of the male screw portion 134 faces the bypass passage 128. The amount of protrusion adjustment can adjust the flow rate ratio of the tap water flowing into the bypass passage 128 from the third opening portion 120.

Here, the opening degree adjustment mechanism 132 does not necessarily have to be constituted by the male screw portion 134 and the female screw portion 133. For example, it can be appropriately selected from known adjustment mechanisms such as a throttle valve, a flow rate adjusting valve, or a shutoff valve. However, in the case where the opening degree adjustment mechanism 132 is constituted by the male screw portion 134 and the female screw portion 133, the structure can be simplified and the productivity can be improved.

Moreover, the female thread portion 133 does not necessarily have to be obtained from the base member. The side surface 109 of the 105 is formed to penetrate substantially perpendicularly to the bypass passage 128. The female screw portion 133 may be formed to penetrate the bypass passage 128 at an acute angle (obtuse angle). However, when the female screw portion 133 is formed to be substantially perpendicular to the bypass passage 128, the amount of protrusion of the male screw portion 134 to the bypass passage 128 can be adjusted by the third opening portion 120 while being visually observed. Therefore, the workability is improved.

In the above-described configuration, the tap water supplied from the inflow pipe 110 flows into the fitting recess 112 through the first opening portion 126 through the first communication passage 126 from the outflow pipe opening portion 130. The tap water flowing into the fitting recess 112 rises in the gap 125 formed on the inner surface of the outer casing 107 and the outer surface of the filter 106, and flows into the filter 106. In the filter 106, after the chlorine component or the like contained in the tap water is removed, it becomes purified water and flows into the hollow portion 121. The purified water that has flowed into the hollow portion 121 passes through the filter support tube 122 and flows out from the second opening portion 119 through the second communication passage 127 to the outflow pipe 111, and is sent to the individual water plug.

At this time, by changing the opening area of the bypass passage 128 by turning the male screw portion 134 of the opening degree adjustment mechanism 132, the residual chlorine concentration contained in the purified water passing through the filter 106 can be adjusted. For example, as shown in Fig. 4(a), by making the amount of protrusion of the front end of the male screw portion 134 toward the bypass passage 128 to the maximum, the opening area of the bypass passage 128 is completely closed, so that the tap water can be made The outflow of the 2 communication path 127 is completely blocked, and the purified water having almost no residual chlorine concentration flows out from the outflow pipe 111.

On the other hand, as shown in Fig. 4(b), the opening of the bypass passage 128 is changed by changing the amount of protrusion of the front end of the male screw portion 134. The area is set to be substantially semi-open, and the purified water containing a certain residual chlorine concentration (0.1 mg/L) satisfying the water quality standard can be discharged from the outflow pipe 111.

Further, as shown in Fig. 4(c), by making the amount of protrusion of the male screw portion 134 of the bypass passage 128 zero, the opening area of the bypass passage 128 is fully opened, and more tap water can be used. The second communication path 127 flows out through the bypass passage 128. Therefore, when the hydrant is not used for a long period of time, the residual chlorine concentration of the purified water remaining in the outflow pipe 111 is increased by setting the opening area of the bypass passage 128 to the fully open state in advance. The deterioration of the disease prevention outflow pipe 111 is not the case.

Here, the amount of protrusion of the male thread portion 134 is not necessarily limited to three stages of full closing, half opening, and full opening. The amount of protrusion of the male screw portion 134 may be changed to four or more stages.

Further, the case where the opening area of the bypass passage 128 is substantially half open is not necessarily limited to a residual chlorine concentration of approximately 0.1 mg/L. The parameters of the diameter of the bypass passage 128, the diameter of the second communication passage 127 through which the clean water flows out, the performance of the filter 106, and the like can be appropriately changed.

Further, when the water purifier 101 is shipped from the factory, the amount of protrusion of the male screw portion 134 is adjusted so that the residual chlorine concentration is 0.1 mg/L. Thereby, in the home in which the water purifier 101 is installed, even if the water plug is not used for a long time, the minimum water quality can be maintained. Further, in the case where the amount of purified water passing through the filter 106 is relatively reduced due to repeated use of the filter 106, the residual chlorine concentration contained in the purified water is inevitably increased. Therefore, the residual chlorine concentration contained in the purified water is not less than 0.1 mg/L, and the purified water which often has a certain water quality standard can be discharged.

As described above, by applying the water purifier of the present invention, it is possible to suppress the generation of corrosion or the occurrence of bacteria in the branch pipes of the water pipe which are retained by the clean water containing no chlorine component for a long time.
