Abstract

PURPOSE:To provide a bathtub water purifier with high purifying efficiency by arranging a filter medium in a tank filter of which the upper whole surface is made as an inflow port and installing an overflow weir between the tank filter and the prestage part of the tank filter. CONSTITUTION:A filter chamber 14 is divided by an overflow weir 45 in right and left. One is made as a front chamber 42 whose bottom part is connected to a suction port 6 through a heater chamber 13, and the other is made as a tank filter 43 in which a filter 41 and a filter medium 44 are housed. The bottom surface of the tank filter 43 is connected to a discharge port 7 through a pump chamber 12. All the upper surface of the tank filter 43 is made as an inflow port, and also bathtub water overflowing the overflow weir 45 enters the upper part of the tank filter 43 from a prechamber 42. Therefore, after the flow of the bathtub water in the tank filter 43 comes into contact almost uniformly with all the filter medium 44 arranged in the tank filter 43, it is transferred to the pump 2 side. The flow taking a shortcut in the tank filter 43 is hardly generated to increase the purifying efficiency.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath water purifying device which purifies bath water in a bath to enable long-term use of bath water.

[0002]

2. Description of the Related Art In recent years, there have been provided baths for home use that allow bathing for 24 hours. in this case,
The bath water in the bathtub can be used for a long period of time.
It must be purified regularly or periodically. For this reason, this type of bath is equipped with a bath water purifying device which sucks up bath water in the bathtub, filters it with a filtering means, and returns it to the bathtub. An example is shown in FIG. In the figure, reference numeral 1 is a body of the purifying device, and a pump 2 and a filter 4 are housed in the body 1 from which a suction port 6 and a discharge port 7 are drawn out. If the pump 2 is operated in a state where 7 is submerged in the bathtub, the bath water sucked from the suction port 6 passes through the filter 4 and then returns from the discharge port 7 to the bathtub as shown by an arrow in the figure. .

[0003]

By the way, in the filter 4 in the above-mentioned conventional example, the inside of the filter chamber 14 is partitioned into the left and right by the filter 41, one of which is the front chamber 42, and the other is the filter medium 4.
4 is stored in the filter tank 43, and when the pump 2 arranged between the filter 4 and the discharge port 7 is operated, the bath water entering the front chamber 42 of the filter 4 from the suction port 6 through the heater chamber 13 But,
After passing through the filter 41 into the filter tank 43, the filter medium 4
After being filtered by No. 4, it was directed to the discharge port 7.

In this case, since the pump 2 is arranged on the rear side of the filter 4, the bath for passing from the front chamber 42 to the discharge port 7 through the filter tank 43 in which the filter medium 44 is stored. When the filter medium 44 is evenly stored in the filter tank 43, the water tries to pass through the filter tank 43 in the shortest path, that is, mainly through only the lower portion of the filter tank 43.
For this reason, the bath water does not evenly contact all of the filter media 44 stored in the storage chamber 43, and therefore the purification efficiency is poor, and the bath water passing through the shortest path has a high flow velocity, so When a substance added with a microorganism that decomposes and removes the source of dirt and odor is used as 44, the fixing of the microorganism is not good, and the effect of decomposing and removing dirt and odor by the microorganism cannot be sufficiently obtained.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a bath water purifying apparatus having a high purification efficiency by a filtering means.

[0006]

SUMMARY OF THE INVENTION The present invention, however, has a circulation path connecting a suction port, a pump and a discharge port to circulate bath water in a bath and to arrange the filtration means in the circulation path. In a bath water purifying apparatus for purifying bath water by means of a filter, the filtering means is formed by arranging a filter material in a filter tank having an inflow port on the entire upper surface, and the filter tank and the preceding stage of the filter tank. It is characterized in that an overflow weir is provided between this part and the part.

[0007]

According to the present invention, the bath water flows over the overflow weir into the inflow port, which is the entire upper surface of the filtration tank, so that the bath water is almost even with respect to all the filtration media in the filtration tank. To contact.

EXAMPLES The present invention will be described in detail below with reference to the illustrated embodiments. The bath water purifying apparatus of the illustrated example can be retrofitted to an existing bath and prevents the temperature of the hot water from decreasing. Sheath heater 3 with a small amount of heat (about 600 W)
The inside of the body 1 in which the suction port 6 and the discharge port 7 are led out from the bottom surface is divided into a pump chamber 12, a heater chamber 13, and a filtration chamber 14. The pump 2 is arranged in the pump chamber 12, and the sheath heater 3 is arranged in the heater chamber 13.

As shown in FIG. 2, the body 1 has the following structure.
It is installed in the corner of the bathtub 9 in the bathroom, and the suction port 6 and the discharge port 7 are located in the bathtub 9. 16 in the figure
Is a bar for preventing the unstable collapse of the body 1 because the center of gravity G is not located on the edge of the bathtub 9 as it is installed on the narrow edge of the bathtub 9. As shown in FIG. A shaft 18 provided at lower portions on both sides of the body 1 is inserted into the long hole 17, and the bar 16 is rotated around the shaft 18 so that the bar 16 can be stored along the side wall of the body 1. You can do it. In order to prevent falling, the bar 16 is centered around the shaft 18.
While rotating and extending in the horizontal direction, the one end of the bar 16 is positioned at the engaging portion 19 by pushing it toward the body 1 side, so that the horizontal state placed on the edge of the bathtub 9 is maintained. . As shown in FIG. 4, the bar 16 may be fixed by inserting it into an engaging portion 19 provided in the body 1.

The filtration chamber 14 of this bath water purifying apparatus is shown in FIG.
As shown in FIG. 2, the overflow chamber is divided into right and left by an overflow weir 45, one of which is a front chamber 42 whose bottom portion is connected to the suction port 6 through the heater chamber 13, and the other is a filtration chamber in which a filter 41 and a filter medium 44 are stored. It is said to be the tank 43, and the filtration tank 43
Is connected to the discharge port 7 via the pump chamber 12. Reference numeral 15 in the figure denotes an inner lid that hermetically closes the upper opening of the filtration chamber 14. As the filter medium 44 stored in the filter tank 43, here, a ball-shaped fiber type filter medium or a ceramic ball-shaped filter medium is used, and microorganisms that decompose and remove the sources of dirt and odor are added. Is used.

However, in this bath water purifying apparatus, the suction port 6 and the discharge port 7 are installed in the vicinity of the bathtub 9 and are submerged in the bath water in the bathtub. The inner lid 15 is removed and each chamber 12, 1
Fill 3, 14 with water. After that, the bath water sucked from the suction port 6 by the operation of the pump 2 enters the filtration tank 43 through the heater chamber 13 and the front chamber 42, and further returns to the inside of the bath from the discharge port 7 through the pump 2. . The discharge port 7 in the present embodiment is of a jet jet discharge type that simultaneously discharges the air sucked through the air flow path 71 due to the pressure drop accompanying the discharge of the bath water.

Here, the entire upper surface of the filter tank 43 serves as an inlet, and the bath water that has passed the overflow weir 45 from the front chamber 42 enters the upper portion of the filter tank 43. The inflow of the bath water into the inside 1 is less likely to be partially biased, and the filter 41 arranged at the inlet portion spreads the bath water over the entire inlet surface. Therefore, the flow of the bath water in the filtration tank 43 moves to the pump 2 side after contacting all the filtering materials 44 arranged in the filtration tank 43 substantially evenly, and short-circuits the inside of the filtration tank 43. The flow is less likely to occur, and therefore the purification efficiency is high.

[0013]

As described above, according to the present invention, since the overflow weir is arranged between the filtration tank having the entire upper surface serving as the inlet and the previous portion of the filtration tank, the bath water is It flows over the overflow weir into the inflow port, which is the entire upper surface of the filtration tank, so that the bath water makes almost uniform contact with all the filtration media in the filtration tank. Therefore, the efficiency of purification by the filter material is high, and the flow velocity of the bath water is slow, so that the effect of degrading dirt and odor using microorganisms can be expected sufficiently.
