Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purifier, and more particularly to a water purifier for purifying raw water by passing it through a tank containing a large number of active materials.

[0002]

2. Description of the Related Art Conventionally, water purifiers have been used to purify water in bathtubs and pools. Among the water purifiers, various types are known as water purifiers for purifying raw water by passing it through a tank containing a large number of active materials. The applicant of the present application has also applied for a water purifying apparatus in which an active material such as barley stone is contained in a mesh cartridge and is detachably mounted in the tank. The raw water sent into the tank is filtered as it passes through the layer of the active material, and is activated by the adsorption and active action of the active material. In the water purifier of the type that uses this active material, when the cumulative amount of purified water increases, adherence of slime composed of bacteria, secretions of bacteria, etc. to the active material progresses. If the adhered amount of slime increases, the active action of the active material becomes dull, and sufficient water purification capacity cannot be exhibited. Therefore, it is necessary to wash the active material. Therefore, conventionally, the active material is taken out of the tank (in the case of the cartridge type, the cartridge is taken out of the tank) and washed with water, or a chemical such as hydrogen peroxide solution is circulated into the tank to dissolve slime and then rinsed. It is washed by doing so.

[0003]

However, the above-mentioned conventional water purifier has the following problems. When removing and cleaning slime, the method of taking out the active material from the tank is troublesome in taking out the active material. Therefore, a backwash method may be considered in which the wash water is fed into the tank from the opposite direction, but since the active material is generally the size of the little finger and is heavy, even if it is simply backwashed, the movement of the active material is almost the same. Therefore, there is a problem that the cleaning effect cannot be improved. Further, in the method using chemicals, there is a problem that rinsing and washing are required, which requires a lot of work and may be dangerous depending on the chemicals used. Therefore, it is an object of the present invention to provide a water purifying apparatus that can effectively wash an active material without taking out the active material from a tank and can wash the active material without using a chemical.

[0004]

In order to solve the above problems, the present invention has the following constitution. That is, in a water purification device that purifies raw water by passing it through a tank containing a large number of active materials, an air supply means for sending compressed air into the tank to remove slime and the like adhering to the active materials. And is provided.

[0005]

[Operation] The operation will be described. It is possible to remove slime and the like adhering to the surface of the active material in the tank by the compressed fluid pressure and bubble pressure sent by the air supply means.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings. FIG. 1 shows a block diagram of the bath water purifier of this embodiment. In the figure, 10 is a bathtub, to which purified water purified is supplied from a water supply port 12. Also, bathtub 1
The water in 0 (raw water) is sent from the drain port 14 to a tank described later for purification. Reference numeral 16 denotes a tank, which is in communication with the bathtub 10 via pipes 18a and 18b. Pipe 1
The inner end of the bathtub 10 of 8a is the water supply port 12, and the pipe 18
The inner end of the bathtub 10 of b is the drain port 14. The raw water sent into the tank 16 via the pipe 18b is
After being purified in 6, it is sent to the bathtub 10 through the pipe 18a. The tank 16 is provided with a lid 20, and the lid 20 is closed during normal operation, but the lid 20 is opened during cleaning and rinsing of the active material cartridge, which will be described later, to prevent water overflowing from the tank 16 and the like. Is discharged to the outside of the tank 16.

Reference numeral 22 denotes a pump, which is a bathtub 10 and a tank 1.
Circulate water between 6. The pump 22 is provided in the middle of the pipe 18a, but the installation position is not particularly limited to this position. Reference numeral 24 denotes an active material cartridge, which will be described later in detail, but is formed of a mesh, and accommodates a large number of bakuhanishi balls 26, which is an example of the active material, inside. The cartridge 24 is attachable to and detachable from the tank 16. The cartridge 24 can be attached and detached by removing the lid 20 of the tank 16. The barley stone ball 26 of this embodiment is formed into a ball shape by sintering a powder of natural barley stone known as an active material in the related art. By using this bakuhanishi ball 26, it is possible to have both the mineral elution property and the adsorptivity of natural bakuhanishi, and the microbial adsorptivity and carrier property of the porous ceramic balls that have been conventionally used. It should be noted that conventional natural barley stone or ceramic balls may be used as the active material.

Now, the active material cartridge 2 will be described with reference to FIG.
The structure of No. 4 will be described. The cartridge 24 is formed in a cylindrical shape, and the inner diameter thereof is gradually reduced toward the inside thereof, and a frustoconical space 28 having an upper bottom surface is formed therein. Because of this space 28, the layer of the boiled rice stone balls 26 becomes thicker as it goes upward. Cartridge 24
The outer peripheral surface and the upper surface, and the inner peripheral surface and the upper bottom surface of the space 28 are formed of mesh, so that the raw water enters the layer of the barley stone balls 26 from the outside of the cartridge 24, is purified, and then exits into the space 28. It has become. The base portion 30 of the cartridge 24 is provided so as to project downward, and can be fitted into and removed from the bottom portion of the tank 16. Cartridge 2
Silicon packing (not shown) between 4 and tank 16
Is inserted to maintain water tightness.

The base 30 has three through holes 32a, 32a.
b and 32c are drilled. The end of the pipe 18a is fitted into the through hole 32a and is raised in the space 28 (see FIG. 1). Therefore, the water purified in the cartridge 24 is introduced into the pipe 18 a in the space 28 and sent to the bath 10. Through holes 32b, 3
Reference numeral 2c is a hole for feeding compressed air, which is formed to feed compressed air sent from an air compressor described later into the cartridge 24 through the space 28. A port 34 for connecting a pipe is vertically provided at a position corresponding to the through holes 32b and 32c on the bottom surface of the base portion 30.

Referring again to FIG. 1, reference numeral 36 is an air compressor which is an air supply means, and sends compressed air into the tank to remove the slime adhering to the cartridge 24 and to the boiled stone ball 26 in the cartridge 24. Give movement. The air compressor 36 is a pipe 18c
The compressed air can be sent into the tank 16 through the sub pipe 18d branched from the pipe 18c. Two of the sub pipes 18d are connected to the port 34 (see FIG. 2) of the cartridge 24. Other subpipe 1
8d communicates with the inside of the tank 16 on the bottom surface of the tank 16. The air compressor 36 is connected to a bubble generator (for example, a blower mat disposed on the bottom surface inside the bathtub 10) installed in the bathtub 10 (not shown) as well as an air supply means, and is used when used as a bubble bath. Is also available.

One end of the pipe 18d is connected to a water supply (not shown). The other end of the pipe 18d is connected to the pipe 18a. By connecting the pipe 18d to the water supply, it is possible to send the cleaning water for rinsing the boiled stone balls 26 into the tank 16. 38a, 3
Reference numerals 8b, 38c, and 38d are valves, and are pipe 18c, pipe 18a, pipe 18b, and pipe 1, respectively.
It is provided to open and close 8d. The valve 38
The valves a, 38b, 38c and 38d close the valves 38a and 38d and open the valves 38b and 38c during the normal operation of the water purifier. When cleaning the cartridge 24, the valves 38b, 38c,
38d is closed and valve 38a is opened. Further, in the case of rinsing after cleaning, the valves 38a and 38d are opened and the valves 38b and 38c are opened.
Close.

Next, the operation of the water purifier having the above structure will be described. During normal operation, the valves 38a and 38d are closed and the valves 38b and 38c are opened, so that the water in the bathtub 10 is moved by the operation of the pump 22 to the pipe 18b and the tank 1.
6, it circulates to the bathtub 10 via the cartridge 24, the space 28 and the pipe 18a. As the water passes through the cartridge 24, it is filtered and activated by the layer of the boiled stone balls 26 and returned to the bath 10. When cleaning the cartridge 24, the valve 3
Since 8b, 38c and 38d are closed and the valve 38a is opened, the compressed air from the air compressor 36 is sent into the tank 16. The compressed air peels off the slime attached to the mesh of the cartridge 24. At this time, particularly when the compressed air is sent to the space 28 in the cartridge 24, the space 28 has a truncated cone shape, and thus the rising compressed air acts as a guide so as to enter the inside of the cartridge 24. When the compressed air enters the cartridge 24, the fluid pressure and the bubble pressure of the compressed air enable the dirt and slime adhering to the surface of the barley stone balls 26 in the cartridge 24 to be blown off, peeled off, and removed.

Further, at the time of rinsing after cleaning, the valve 38
Since a and 38d are opened and valves 38b and 38c are closed, fresh wash water is supplied from the tap water into the tank 16 from the tap water while removing slime by compressed air, and thus peeled from the cartridge 24 and the barley stone ball 26. You can rinse out the slime. Since the lid 20 is opened during cleaning and rinsing, dirty water can be discharged to the outside of the tank 16.

Next, another embodiment of the active material cartridge will be described with reference to FIGS. The cartridge 24 of the previous embodiment is of a type suitable for cleaning the bathtub 10 having a relatively small capacity, but an active material cartridge having a large capacity is required for cleaning a pool or a large bath. At that time, a large cartridge may be provided, but when the cartridge becomes large, the weight naturally becomes large, which makes maintenance difficult. Therefore, the cartridge 100 of FIG.
02a, 102b, 102c in multiple stages (3 stages in FIG. 3)
They are stacked to form one large capacity cartridge 100. A frustoconical space 104a having an upper bottom surface is formed in the sub cartridge 102a. On the other hand, frustoconical spaces 104b and 104c formed in through holes are formed in the sub cartridges 102b and 102c.
As a result, the sub cartridges 102a, 102b, 10
When two cartridges 2c are stacked in three layers to form one cartridge 100, a truncated cone-shaped space 10 having one upper bottom surface inside is formed.
4 is formed. Base 10 of sub cartridge 102c
6 is provided with a port 108 for introducing compressed air so that compressed air from the air compressor can be sent into the space 104 at the time of cleaning and rinsing.

The cartridge 200 shown in FIG. 4 is an example in which a plurality of (four in FIG. 4) sub cartridges 202 are attached to one base portion 204. The total capacity of the four sub cartridges 202 is the capacity of the cartridge 200. A frustoconical space 206 having an upper bottom surface is formed inside each sub-cartridge 202.
The base portion 204 is provided with a port (not shown) for introducing compressed air into each sub-cartridge 202, and compressed air from the air compressor can be sent into each space 206 during cleaning and rinsing. Although various preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments. For example, an air chamber is provided at the bottom of the active material cartridge, and the air chamber and the inside of the cartridge are provided. It is needless to say that many modifications can be made without departing from the spirit of the invention, for example, a large number of communicating holes may be provided to send compressed air into the air chamber.
