[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purification device that filters water introduced from an external water source and discharges it as purified water suitable for drinking water or the like.

0002

[Prior Art] A conventional water purification device has a structure in which a filtration chamber communicating with the inlet and a purified water reservoir chamber communicating with the discharge port are partitioned by a partition wall in a housing having an inlet and a discharge port. ing. A filter body made of a hollow fiber membrane bundle, activated carbon, or the like is housed in this filtration chamber, and a purified water discharge section, which is an output section of the filter body, faces the purified water storage chamber.

[0003] This water purification device is used by connecting the inlet to, for example, a water supply pipe through an on-off valve, or directly connected to a water faucet, and purifying water by opening and closing the on-off valve or the water faucet. Discharge or stop.

0004

[Problems to be Solved by the Invention] The water purification device described above can discharge tap water as purified water, but if you want to obtain cold purified water, you can put the purified water in a container and cool it in a refrigerator, or add ice to the purified water. You have to put it in and put it on the lock, which is a hassle.

The present invention was made in view of the above circumstances, and its object is to provide a water purification device that can obtain cold purified water without requiring any troublesome effort.

[0006]

[Means for Solving the Problems] In order to achieve the above object, the water purification device of the present invention includes a water purification means for filtering water introduced from an inlet and discharging it as purified water from an outlet of a purification water storage chamber; A tank that communicates with a purified water storage chamber to allow purified water to be introduced and that communicates with a discharge port to allow purified water to be drawn out, a cooling means that cools purified water in the tank, and a pump that sends purified water in the tank to the discharge port. , and control means for controlling starting and stopping of the pump.

[0007]

[Operation] According to this construction, the purified water in the purified water storage chamber is introduced into the tank, the purified water is cooled in the tank, and the cold purified water can be discharged from the discharge port by starting the pump. Furthermore, when the pump is stopped, the purified water in the purified water storage chamber can be discharged from the outlet without passing through the tank.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

A is a water purification means, which has an inlet 1 provided at the bottom.
A housing 1 having a discharge port 1b provided above and a filter chamber 2 which communicates with the inlet port 1a and a purified water storage chamber 3 which communicates with the discharge port 1b are partitioned by a partition wall 4. . A communication port 3a for communicating with a tank to be described later is provided at the lower side of the purified water storage chamber 3. Moreover, in this filtration chamber 2, a filter body 5 consisting of a first filter 7 whose main component is a hollow fiber membrane bundle 6 and a second filter 9 whose main component is activated carbon 8 or the like is housed. The first filter 7 has a cylindrical case 7
A hollow fiber membrane bundle 6 is in an open state and fixed in a U-shape with a potting material at the upper open end of the hollow fiber membrane bundle 6, and the opening of the hollow fiber membrane bundle 6, which is an output part as a filter body 5, is used to discharge purified water. The case 7a is fixed to the partition wall 4 in a sealed state so that the case 7a faces the purified water storage chamber 3. The second filter 9 is a cylindrical case 9a with a bottom that has an inner diameter larger than that of the case 7a, and is filled with granular activated carbon 8 except for the volume occupied by the case 7a, and has a lid with an opening for water passage. The body 9b closes the opening and is fixed to the case 9a described above. The second filter 9 removes chlorine odor and organic matter, and the first filter 7 removes grime, mold, rust, and microorganisms such as bacteria.

Reference numeral 10 denotes a tank, which is made of a material with high thermal conductivity such as aluminum and is formed into a rectangular parallelepiped shape, and inside thereof there are two partition plates 11 in which water passage portions are vertically positioned alternately in order to meander the water flow. , 11 are provided. In addition, a heat insulating material 1 is provided on the outer surface of the tank 10 to provide a heat insulating effect.
2 is provided. Furthermore, the partition plate 11 on the right side in the figure
An inlet 10a communicating with the communication port 3a of the purified water storage chamber 3 is provided on the upper surface of the chamber separated by The discharge port 10b is connected to the discharge port 1b.

Reference numeral 13 denotes a cooling means, which includes a Peltier element 14 disposed in the upper part of the side surface of the tank 10 with the heat insulating material 12 partially removed, and heat dissipation fins 15 closely fixed to the Peltier element 14. , and a fan motor 16 that sends air to promote heat dissipation from the fins 15. The fan motor 16 is constantly rotated by a low-voltage DC power source 17. This cooling means 13 cools the Peltier element 14 into the tank 1.
Since it is provided near the top of the tank 10, purified water that has been cooled and has a high specific gravity naturally flows downward, thereby facilitating convection of the purified water in the tank 10.

Reference numeral 18 denotes a pump, which is a gear pump or the like operated by the low-voltage DC power supply 17, and is inserted between the outlet 10b and the outlet 1b to pump the purified water in the tank 10 from the outlet 10b to the outlet. Send it to 1b.

Reference numeral 19 denotes control means, which includes an ON switch 20 and an OFF switch 21 for controlling starting and stopping of the pump 18. When the ON switch 20 is operated, the pump 18 is started and purified water in the tank 10 is sent to the discharge port 1b, and when the OFF switch 21 is operated, the pump 18 is stopped and purified water is no longer sent to the discharge port 1b. In this case, water sent into the inlet 1a from the on-off valve or water tap is filtered and purified, but is discharged from the outlet 1b without being introduced into the tank 10. Accordingly, the tank 10 allows or disables the introduction and withdrawal of purified water from the purified water storage chamber 3 by the action of the pump 18.

[0014] In this water purification device, when the on-off valve 22 or the water faucet is opened, purified water that has been cooled by operating the ON switch 20 is continuously discharged from the discharge port 1b. Moreover, when the OFF switch 21 is operated at this time, purified water is continuously discharged from the discharge port 1b without being cooled. Note that when the on-off valve 22 or the water faucet is closed, the cooled water in the tank 10 is discharged until the remaining purified water is exhausted by operating the ON switch 20. Further, even if the OFF switch 21 is operated at this time, purified water will not be discharged. Furthermore, by providing the partition plates 11, 11 in the tank 10, when the cooled purified water is taken out continuously, the temperature of the purified water that has already been cooled by the unchilled purified water introduced into the tank 10 is suddenly reduced. I'm trying to keep myself from getting angry.

As shown in FIGS. 3 and 4, when disposed inside the sink 23, the outer shell dimension of the tank 10 portion in the depth direction of the sink 23 is made smaller than the outer dimension of the housing 1. The tank 10 portion may be located at the inner side of the periphery of the sink 23 to effectively utilize the space on the top surface of the sink 23.

[0016]

[Effects of the Invention] With the above-described configuration, the water purification device of the present invention can obtain cooled purified water by operating a switch, thereby eliminating the troublesome conventional method of producing cold purified water.
