Description

TECHNICAL FIELD [0001] The present invention relates to a timer switching valve and a water regeneration water softener having the same,

The present invention relates to a timer switching valve and a water regeneration type water softener having the same, and more particularly, to a timer switching valve comprising a valve top plate and a valve bottom plate which are in close contact with each other, And a water regeneration type water softener provided with the timer switching valve.

Currently, a water softener installed at a home or office has a basic function of chemically converting water-soluble ions contained in tap water into soft water.

In general, tap water (hard water) contains a large amount of chlorine components used in the purification process, and also contains various heavy metals (ions) such as iron, zinc, lead and mercury which are harmful to human body due to old pipes and water pollution . Although such tap water is not fatal to the human body, if it is used as it is when washing the skin, the metal ion contained in the water and the fatty acid of the soap are combined with each other to produce a metallic foreign substance. Such metallic foreign substances come into contact with the skin, It causes skin diseases or promotes aging of the skin.

In order to prevent this, a water softener was developed which exchanges hardness components Ca2 + and Mg2 + with Na + in the ionic resin by passing tap water through a strongly acidic cation exchange resin of Na + type and is mainly used for cleaning have.

The water softener has a principle of softening Ca2 + and Mg2 + contained in hard water by Na + substitution. For this purpose, the water tank contains a resin tank containing an ion exchange resin of a special polymer compound containing Na + as an essential component. And an ion exchange resin regenerating material such as salt (NaCl) which generates Na + in case or a regenerator in which a regenerant is incorporated.

That is, in the water softener, soft water is continuously passed through the resin tank in contact with the ion exchange resin in a state where a large amount of fine ion exchange resin is stored in the resin tank, thereby producing soft water. The Na + component is reduced by the continuous contact with the hard water, and the NaCl component regenerated water is flowed from the regeneration tank to the resin tank in order to preserve it.

Conventional water softeners generally include a resin tank containing ionic resin which converts raw water supplied from the outside into soft water and a regeneration tank filled with salt for regenerating the regenerated water to restore the ionic resin when the performance of the ionic resin deteriorates do.

The resin tank and the regenerator are connected to the water supply port, the shower means, the water tank outlet, and the like through a connection pipe such as a pipe and a channel switching valve module.

The flow path switching valve module is formed with a flow path, a flow path, and a flow path groove therein so that raw water, soft water, and regenerated water can be sent to each part of the water softener system. That is, the raw water supplied from the outside is supplied to the resin tank and the regenerator, and the flow path is formed so that the softened water can be discharged to the outside by passing the ion water of the resin tank.

After producing the soft water using the resin tank for a certain period of time, it is necessary to constantly supply the raw water to the regenerator for a predetermined period of time during the regeneration process so that the regeneration operation can be performed without difficulty. There is a problem that not only the inconvenience but also the supply of the appropriate raw water necessary for the regeneration is not easy.

On the other hand, the conventional switching valve module has various complicated flow paths formed on the valve top plate and the bottom plate, which can act as obstacles to the flow of the fluid, and there is a possibility that it is difficult to accurately open and close the flow path.

In addition, there is a problem that sliding movement is not smooth due to the close contact of the valve upper and lower plates under the action of water pressure due to the water flowing into the valve housing accommodating the valve upper plate and the lower plate. As described above, if the movement between the valve upper and lower plates in the switching valve module is not smooth, the driving power may be increased and the wear of the component may be increased.

The overall configuration of the water softener 1000

1, the water softener 1000 includes a timer switching valve 200 for converting a flow path for soft water, raw water, and regenerated water, a filter unit 300 for rectifying the supplied raw water, A resin tank part 500 for storing ionic water and producing soft water, and a cumulative flow meter 600 for calculating the flow rate of the discharged soft water.

First, we look at the flow of the whole enemy, the training, and the reproduction.

The flow direction of the raw water flowing from the water inlet 10 through the original import feeding path 110 is determined by the timer switching valve 200. When the valve mode is set to the raw water mode using the valve shaft 290 of the timer switching valve 200, the supplied raw water is directly discharged through the outflow channel 620. In the raw water mode, the user can use untreated water as it is.

On the other hand, when the valve shaft 290 is set to the training mode, the supplied raw water moves to the filter unit 300 through the filter unit intake flow path 310. The raw water having a rectifying action in the filter unit 300 is transferred to the resin tank unit 500 having a plurality of columns through the resin tank distributing channel 520 to perform the softening operation. Thereafter, the softened water is discharged through the soft water outflow channel 610, the integrated flow meter 600, and the outflow channel 620.

When the regeneration mode is set using the valve shaft 290, the supplied raw water is transferred to the regeneration tank 400 through the regeneration tank inlet flow path 410. The regenerated water generated in the regenerator 400 is divided into a plurality of columns on the resin tank part 500 through the resin tank distributing passage 520 and regenerated in the resin tank part 500, The flow path 610, and the outflow channel 620, as shown in Fig.

The timer switch valve 200 receives the raw water from the water inlet 10 through the original import feeding path 110 and supplies it to the filter unit 300, the regenerator 400, and the second exhaust channel 620 . The timer switching valve 200 allows the supply of raw water for regeneration to be accurately performed for a predetermined time by using a timer function. The detailed features will be described below.

The filter unit 300 can communicate with the timer switching valve 200 through the filter-unit intake flow path 310, and functions to primarily filter foreign matter in the supplied raw water. The material accommodated for the function of the filter unit 300 is not limited unless it is harmful to the human body, and various methods such as activated carbon, reverse osmosis, hollow fiber membrane, and ionization may be used as the rectification method.

The regenerator 400 may be supplied with a flow rate of 150 ml / min, which is a constant flow rate of the raw water flowing through the regeneration passage flow path 410 in accordance with the predetermined reference amount. In the case where the regeneration mode is started, the regeneration unit 400 itself can set the reference inflow amount and check the amount of raw water flowing when the regeneration unit 400 operates. In the meantime, according to the present invention, when water is left in the regenerator 400 after the regeneration is completed, the water is automatically discharged, thereby preventing an accidental risk that may occur due to a high internal pressure in the regenerator 400 .

The resin tank portion 500 is made up of a plurality of columns, and softening occurs in each column. As described above, it is easy to adjust the softened water to a desired temperature by a plurality of divided inner structures.

The integrated flowmeter 600 is a device that measures the amount of discharged water through the resin tank unit 500 and measures the regeneration time, and it is possible to visually confirm the reproduction time point directly through the indicator 666 exposed to the outside . The integrated flow meter 600 senses the flow rate through the rotation of the impeller (not shown) disposed on the soft water outflow channel 610 and receives the flow rate through the non-contact type material to detect the accumulated oil amount for the soft water without any external power .

The first gear 232 can be rotationally driven by a restoring force to return to the original state when the timer spring is wound. The first gear 232 is arranged to engage with a second gear 292 connected to the valve shaft 290 where the first tooth 234 and the second tooth 294 are engaged with the gears 232, and 292, respectively.

The valve lower plate 240 is formed of a circular ceramic material having a predetermined thickness. The lower valve plate 240 is formed with a plurality of flow holes to pass through the upper and lower surfaces thereof. The flow hole includes a softening hole 241, a raw water hole 242, and a regeneration hole 243. The training hole 241 and the raw water hole 242 may have a fan shape or a triangle shape with respect to the center of the valve lower plate 240. This shape reduces the overall area of the valve lower plate 240 when compared with the shape of the through hole formed in the conventional circular shape, thereby enabling a compact design to be realized. On the other hand, the reproduction hole 243 can be formed in an arc shape having a predetermined thickness.

A first fixing groove 244 is formed in the lower end of the valve lower plate 240. The first fixing groove 244 is engaged with the first protrusion 214 formed in the valve housing 210 to thereby connect the valve lower plate 240 And is fixed in the valve housing 210 without rocking.

The valve upper plate 250 is formed of a circular ceramic material having a predetermined thickness in the same manner as the valve lower plate 240. The valve upper and lower plates 240 and 250 are preferably made of a ceramic material with which mutual friction can be minimized. The inlet port 252 is preferably formed in a triangular shape so as to correspond to the shape of the soft water hole 241 and the raw water hole 242 . At the upper end of the valve top plate 250, a second fixing groove 254 is formed for fixing to the coupling body 260.

The connecting body 260 serves to connect the valve top plate 250 and the valve shaft 290. A shaft 261 is formed at the center thereof and a second projection 264 protruded downward is formed at the lower side end do. The second protrusion 264 is engaged with the second fixing groove 254 to fix the coupling member 260 to the valve top plate 250 without rocking.

A plurality of fastening holes 276 corresponding to the fastening grooves 216 formed at the upper end of the valve housing 210 are formed on the rim of the upper lid 270. In order to prevent leakage of water contained in the valve housing 210, a separate watertight member (not shown) is provided between the valve housing 210 and the upper lid 270, Lt; / RTI > may be disposed.

Hereinafter, a structure for reducing the load acting between the valve top plate 250 and the valve lower plate 240 by the water pressure in the valve housing 210 will be described with reference to FIG. The water supply hole 241 of the valve lower plate 240, the raw water hole 242 and the regeneration hole 243 maintain a structure protruding upward from the upper end of the valve lower plate 240 by the valve level difference 245. [ The valve level difference 245 means the distance between the valve top plate 250 and the valve lower plate 240. The valve level difference 245 is a distance between the valve top plate 250 and the valve lower plate 240. Raw water introduced into the valve housing 210 flows into the valve upper and lower plates 240, .

That is, the raw water flowing between the valve upper and lower plates 240 and 250 acts to buffer the lower portion of the valve lower plate 240 and the upper portion of the valve upper plate 250. The valve top plate 250 can be driven by providing the minimum rotational force through the valve shaft 290 because the frictional force against the valve lower plate 240 is largely canceled through the action of the force as described above.

The change in the flow rate in the timer switching valve 200

5 to 8, the state of the passage change in the timer switching valve 200 by the relative arrangement between the valve top plate 250 and the valve lower plate 240 will be described.

First, the softening process for the supplied raw water will be described with reference to FIG.

The intake port 252 of the valve top plate 250 is disposed on the softening hole 241 of the valve lower plate 240. The above process is enabled by rotating the valve top plate 250 interlocked with the valve shaft 290 and the connecting body 260. In this state, the raw water hole 242 and the regeneration hole 243 of the valve lower plate 240 are clogged to stop the flow of raw water.

The flow of water in the training state is as follows. Where - is defined as an indication of the flow of water.

The water inlet pipe 10 is connected to the inlet of the raw water supply passage 110 through the valve housing 210. The inlet port 252 is connected to the water supply hole 241, A filter unit 300, a resin tank unit 500, an integrated flow meter 600, an outflow channel 620,

Next, with reference to FIG. 6, a process of supplying raw water supplied without a training process will be described. The inlet port 252 of the valve top plate 250 is disposed on the raw water hole 242 of the valve lower plate 240. The above process is enabled by rotating the valve shaft 290 at a constant angle clockwise or counterclockwise. In this state, the softening hole 241 and the regeneration hole 243 of the valve lower plate 240 are clogged to stop the flow to the resin tank 500 and the regenerator 400.

The water inlet 10 is connected to the main importing passage 110 through the valve housing 210. The inlet port 252 is connected to the raw water hole 242 through the raw water outlet 212,

Next, with reference to FIGS. 7 and 8, a process of reproducing using the supplied raw water will be described. 7, it can be seen that the inlet port 252 of the valve top plate 250 opens only one side of the regeneration hole 243. In this state, the timer 230 can be used to set the valve top plate 250 to rotate in the clockwise direction for a predetermined playback time. The playback time can be set by a timer spring incorporated in the timer 230. In the present invention, for example, the timer spring force is adjusted to set the playback time to 20 minutes. The restoring force of the timer spring is transmitted to the valve top plate 250 through the first gear 232 and the second gear 292. The first and second teeth 234 and 294 formed on the outer periphery of the gears 232 and 292, So that an accurate rotation is achieved. 8, when the rotation driving by the timer 230 is completed, the inlet port 252 of the valve top plate 250 passes through the other side end of the reconditioning hole 243 and between the reconditioning hole 243 and the softening hole 241 It is located in space.

The flow of water in the regeneration state is as follows.

The water inlet pipe 10 is connected to the main importing passage 110 through the valve housing 210. The inlet port 252 is connected to the regeneration hole 241 through the regeneration water outlet 213, ) - regenerator (400) - resin tank distribution channel (520) - resin tank part (500) - resin tank outflow channel (530) - outflow channel (620)

The regeneration operation process of the water softener 1000 by the timer switching valve 200

When the exchange cycle of the ion resin is displayed on the integrated flow meter 600 during the training process for the raw water supplied through the resin tank unit 500, the user rotates the valve shaft 290 to start the regeneration process. The valve shaft 290 is rotated counterclockwise for the regeneration process so that the first tooth 234 of the first gear 232 and the second tooth 294 of the second gear 292 engage with each other. The second tooth 294 is divided into a first point 295 at which the first gear 232 and the second gear 292 are first engaged and a second point 296 at which the engagement ends.

When the first gear 232 rotates in the counterclockwise direction, the second gear 232 rotates clockwise from the first point 295, and the timer spring in the timer 230 is wound. Thereafter, the rotation of the valve shaft 290 is stopped before passing through the second point 296. The above process is a pre-stage for regeneration. By rotating the first gear 232 and the second gear 292 in accordance with the nature of the rolled timer spring to be restored, the valve top plate 250 is rotated by the valve lower plate 240).

During the process of the inlet port 252 of the valve top plate 250 passing through the regeneration hole 243 of the valve lower plate 240 a continuous regeneration operation is performed and the inlet port 252 is no longer positioned on the regeneration hole 243 The flow of the raw water through the regeneration hole 243 is blocked and the regeneration process is terminated.

As described above, according to the present invention, the regeneration process is uniformly maintained for a predetermined period of time by using the timer switching valve 200, and the valve step 245 is provided to cancel the load acting between the valve upper and lower plates 240 and 250 The driving force transmission in the timer switching valve 200 is smoothly performed in the regeneration process. In addition, it is possible to reduce the volume of the valve housing by improving the shape of the through holes formed in the valve top plate 250 and the lower plate 240, and to minimize unnecessary flow loss during the flow of raw water in the valve housing.
