Dissolved air water generating module and shower provided with same

Technical Field

The present invention relates to a gas-dissolved water generating module and a shower provided with the same, and more particularly to a gas-dissolved water generating module that generates fluid from a faucet as gas-dissolved water supply and injects gas-dissolved water as microbubble fluid, and a shower provided with the same.

Background

The washing objects may be articles such as tableware and vegetables and food-class as well as human and biological-class such as animals. The cleaning object has inherent surface roughness depending on the material thereof. For example, the inherent surface roughness of materials such as tableware is different from the inherent surface roughness of human skin, and the cleaning time and method may be different from each other.

Among them, water, which is one of substances having a surface tension greater than that of other substances, is mainly used in the washing. The cleaning of the cleaning object with water is performed by using the surface tension of water, but the cleaning efficiency is low because water cannot penetrate into the contaminants remaining on the surface of the cleaning object in practice. In order to prevent the reduction of the washing efficiency in washing with water, tableware and human bodies are washed with a detergent, soap, or the like to which a surfactant is added, but in general, a product to which a surfactant is added contains chemical components harmful to human bodies.

On the other hand, in washing of a human body, for example, in washing of a human body such as a shower, a shampoo, a body wash, or the like to which a surfactant is added is generally used to improve washing efficiency, but as described above, chemical components harmful to a human body are often contained therein, and therefore, an alternative method is required. For example, as described in "microbubble generation device and microbubble generation method" in japanese patent laid-open No. 6334434, there is provided an environmentally friendly cleaning method that adds physical factors to a fluid (where the fluid represents general water) received from a faucet to generate a dissolved air water and sprays it as a microbubble fluid, thereby improving cleaning ability and being harmless to a human body.

However, although the microbubble fluid used for cleaning can be generated and supplied by the dissolved gas water as described in the conventional literature, there is a problem that the inside of the container is contaminated because the dissolved gas water remaining inside the container cannot be discharged after the microbubble fluid is supplied.

Further, since the contamination of the dissolved air water remaining in the container causes bad odor and the like, there is a problem that the user feels uncomfortable when taking a shower.

The shower 10 of the present embodiment includes a water-dissolved gas generating assembly 100 and a shower head 500. The shower 10 of the embodiment of the present invention connects the gas-dissolved water generating assembly 100 for generating gas-dissolved water with the shower head 500 for showering. However, as described above, the dissolved air water generating assembly 100 of the embodiment of the present invention may be used separately from the shower head 500 and separately connected to a kitchen faucet (not shown) or the like.

As shown in fig. 3 to 10, the gas-dissolved water generating module 100 according to the embodiment of the present invention includes a housing 120, a bubble generating portion 140, and a water drain valve 190. In addition, the gas-dissolved water generating module 100 according to the embodiment of the present invention further includes a diffuser 160 and an air discharge unit 170. The gas-dissolved water generating module 100 according to the embodiment of the present invention is described as being disposed between a faucet, not shown, and the shower head 500, but is not limited thereto, and can be connected to various facilities such as a kitchen faucet.

The housing 120 is coupled to the faucet to receive fluid from the faucet. The housing 120 of the present invention includes a housing body 122, a supply port 124, and a discharge port 126. In addition, the housing 120 further includes a drain channel 128.

The housing body 122 is coupled to a water tap for supplying fluid. The housing main body 122 is formed with a supply port 124 for receiving a fluid from a faucet, and a discharge port 126 is formed at a lower portion of the housing main body 122, the discharge port 126 discharging the fluid and the dissolved air water from the supply port 124 to the shower head 500. Here, the supply port 124 and the discharge port 126 are arranged in an L-shape in the case of the cross-sectional shape as a reference. That is, the fluid descending from the supply port 124 and the dissolved air water generated from the supplied fluid are contained in the casing main body 122, and the contained dissolved air water is discharged through the discharge port 126 horizontally disposed at the lower portion of the casing main body 122. On the other hand, a drain passage 128 for discharging the residual dissolved air water in the same direction as the supply port 124 is formed in the lower portion of the housing main body 122.

The bubble generating portion 140 is disposed between the supply port 124 and the discharge port 126 in the casing 120. The bubble generating portion 140 serves to generate bubbles in the fluid supplied from the supply port 124 and supply the bubbles to the inside of the housing 120. Specifically, the bubble generating portion 140 generates bubbles in the fluid supplied to the bottom surface, and the bubbles generated inside the bubble generating portion 140 overflow along the inner wall of the bubble generating portion 140. At this time, the bubbles overflowing from the bubble generating portion 140 are dissolved in the air inside the case 120, and the dissolved air is generated inside the case 120. The bubble generating portion 140 of the present invention includes a bubble generating portion casing 142, a water drain hole 144, an open portion 146, and a closed portion 148.

As shown in fig. 3, 5, 7, and 9, the bubble generating portion casing 142 is formed in a cylindrical shape having a smaller cross-sectional area in a direction perpendicular to the fluid supply direction than the casing main body 122. Specifically, the diameter of the bubble generating portion casing 142 is smaller than the diameter of the cross section of the casing main body 122.

The drain hole 144 is formed through the closing portion 148. The drain hole 144 is for discharging the solution water stored in the bottom of the case 142 for the bubble generating portion to the outside of the case 142 for the bubble generating portion. Specifically, the drain holes 144 are used to discharge the fluid and/or the air-dissolved water contained in the bottom of the shell 142 for the bubble generating portion to the outside of the shell 142 for the bubble generating portion, so as to prevent the fluid and/or the air-dissolved water from being retained in the bottom of the shell 142 for the bubble generating portion having a cylindrical shape.

The open section 146 and the closed section 148 are formed in the bubble generating section casing 142. The opening portion 146 is disposed adjacent to the supply port 124 of the housing 120, and supplies the fluid from the supply port 124 to the bubble generating portion housing 142. The closed portion 148 is formed at a lower portion of the bubble generating portion casing 142 facing the open portion 146. The closed portion 148 collides with the fluid supplied through the open portion 146, and bubbles are generated inside the bubble generating portion casing 142.

The diffuser nozzle portion 160 has a skirt (skirt) shaped cross-sectional shape with a cross-sectional area increasing from the upstream side to the downstream side in the fluid flow direction, and is disposed at the supply port 124 of the casing 120. The diffuser nozzle portion 160 is used to eject fluid from the faucet into the interior of the housing 120, and particularly, into the interior of the bubble generating portion 140 to generate bubbles.

The air discharge unit 170 is disposed at an upper portion of the case 120, and removes pressure inside the case 120. That is, the air discharge part 170 serves to introduce external air into the inside of the case 120 to reduce the pressure inside the case 120 when the pressure inside the case 120 is higher than a predetermined pressure.

The drain valve 190 is disposed at a lower portion of the case 120. The water discharge valve 190 selectively operates according to the dissolved air contained in the casing 120 and the dissolved air discharged to the outside of the casing 120. The water drain valve 190 is used to discharge the dissolved air remaining in the casing 120 to the outside of the casing 120. For example, after the dissolved air water stored in the case 120 is discharged through the outlet 126 and the shower 10, when the faucet and the shower head 500 are closed, the drain valve 190 discharges the dissolved air water remaining in the case 120 to the outside of the case 120. In this way, the water drain valve 190 can discharge the residual dissolved air water to the outside of the casing 120, thereby preventing the contamination of the dissolved air water remaining in the inside of the casing 120 and the contamination of the inside of the casing 120.

The water discharge valve 190 reciprocates between a closed position for closing the water discharge passage 128 for discharging the remaining dissolved air water when the dissolved air water is stored inside the casing 120 and an open position for opening the water discharge passage 128 for discharging the dissolved air water remaining inside the casing 120 after the dissolved air water is discharged to the outside of the casing 120 through the discharge port 126.

Specifically, as shown in fig. 3 and 4, the bleeder valve 190 is in an open position. As shown in fig. 5 and 6, when the fluid is supplied and the water-containing solution starts to be stored in the case 120, the water discharge valve 190 is separated from the open position by the pressure rise and is located at the closed position. As shown in fig. 7 and 8, when the water-dissolved gas is continuously generated, the water discharge valve 190 is located at the closed position due to the pressure rise. When the user takes a shower or turns off the faucet, the gas-dissolved water contained in the interior of the housing 120 is discharged through the discharge port 126. At this time, as shown in fig. 9 and 10, the discharge valve 190 moves from the closed position to the open position as the pressure inside the housing 120 is released. When the water discharge valve 190 is located at the open position, the remaining water-dissolved air is discharged to the outside of the case 120 through the water discharge passage 128 and the water discharge passage 194.

The utility model discloses a valve 190 that drains includes valve main part 192, the passageway 194 that drains, case 196 and elastomeric element 198. The valve main body 192 communicates with the drain passage 128 of the housing 120, and a drain passage 194 for discharging the dissolved air water remaining in the housing 120 is formed. The valve body 196 is disposed inside the valve main body 192. The valve body 196 reciprocates between a closed position and an open position to open and close the discharge passage 194. The resilient member 198 provides a spring force to move the valve element 196 from the closed position to the open position. That is, the elastic member 198 applies an elastic force to the valve element 196 to move to the open position when the pressure inside the housing 120 is released after the valve element 196 moves to the closed position due to the pressure rise inside the housing 120.

Fig. 11 is a perspective view of the showerhead shown in fig. 1, fig. 12 is a sectional view taken along line XII-XII shown in fig. 11, and fig. 13 is a partial sectional view taken along line XIII-XIII shown in fig. 11.

As shown in fig. 11 to 13, a shower head 500 according to an embodiment of the present invention includes a first body 510, a second body 520, and an opening and closing part 530. In addition, the shower head 500 of the embodiment of the present invention further includes a rust preventive water filter 540, an nozzle portion 560, a vitamin filter 580, and an antibacterial filter 590.

The first body 510 is connected to the dissolved gas water generating module 100 through a hose or the like for flowing a fluid. The second body 520 is detachably coupled to the first body 510, and is formed with an injection port 522 for injecting the dissolved gas water flowing from the dissolved gas water generating assembly 100 in a microbubble fluid manner. The opening/closing part 530 is disposed between the first body 510 and the second body 520. The opening and closing part 530 selectively opens and closes a flow passage of the dissolved air water flowing from the first body 510 to the second body 520. The opening and closing part 530 serves to selectively open and close the flow passage of the dissolved air water to selectively inject the microbubble fluid. As an embodiment of the present invention, the opening/closing part 530 may have a sliding structure, and may be a rotary type or the like, in addition to the sliding type.

The rust preventive filter 540 is disposed inside the first body 510, and filters rust components in the dissolved air when the dissolved air flowing to the second body 520 contains the rust components.

The nozzle unit 560 is disposed between the injection port 522 and the opening/closing unit 530, and is formed of a plurality of orifices having a smaller cross-sectional area than the flow passage. The nozzle unit 560 increases the flow rate of the solution of water flowing from the opening/closing unit 530 to the jet port 522.

Vitamin filter 580 and antibacterial filter 590 are disposed between jet opening 522 and opening/closing unit 530. The vitamin filter 580 and the antibacterial filter 590 are used to filter residual chlorine and bacteria in the dissolved air water. Of course, when residual chlorine and bacteria are present in the dissolved air flowing to the shower head 500, the residual chlorine and bacteria are filtered by the vitamin filter 580 and the antibacterial filter 590. As described above, the vitamin filter 580 and the antibacterial filter 590 are not limited, and various ceramic ball filters including the antibacterial filter 590 may be used.

Therefore, the drain passage in the housing for generating the gas-dissolved water can be selectively opened and closed by the water drain valve to discharge the gas-dissolved water remaining in the housing to the outside of the housing, and therefore, the contamination of the remaining gas-dissolved water fluid can be prevented and the contamination of the interior of the housing can be prevented.

In addition, since a plurality of filters for filtering rust water, residual chlorine, and bacteria are disposed inside the shower head for spraying the microbubble fluid and the open/close unit selectively opens/closes the flow path of the dissolved air water sprayed by the microbubble fluid through the shower head, the operational reliability and convenience of the shower head can be improved.

Although the embodiments of the present invention have been described with reference to the drawings, those skilled in the art will appreciate that the embodiments of the present invention can be implemented in other specific forms without departing from the technical spirit or essential characteristics of the present invention. The various embodiments described above are therefore to be understood as being in all aspects illustrative and not restrictive.
