Abstract

PURPOSE:To supply safe and harmless function by sterilization even when various bacteria invade from a water storage tank and a supply port by providing sterilizing devices at two places on the inlet and outlet sides in a treatment circuit. CONSTITUTION:At first, the water in a water storage tank 2 is sent to a filtering and deodorizing device 4 through a pressure pump 3 to remove a bleaching powder smell and a moldy smell. Next, the water is sent to the first sterilizing device 5 to sterilize the original bacteria in tap water and the bacteria invading from the tank 2. The sterilized water is branched to be supplied to an alkali ion water making device 6, a mineral carbonated water making device 7, a bypass pipe 8 and a soft water making device 9. Thereafter, the water is again sterilized by the second sterilizing device 15 to be supplied to a drinking water supply port 17 through an opening and closing valve 16. This sterilizing device 15 shows effect when bacteria invade from the supply port 17 to go upstream through piping.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a water generator that creates drinking water (functional water) with various properties.

[Conventional technology]

Conventionally, there are individual water generators such as water purifiers using activated carbon, alkaline ionized water generators, carbonated water generators, soft water generators, and mineral water generators, but there are many types of water generators that combine multiple functional waters into one. There is no equipment to supply it.

[Problem to be solved by the invention]

The water supplied by the various water generators described above has different uses. For example: - Activated carbon water purifier: Suitable for drinking as there is no chlorine or mold odor.

・Alkaline ionized water maker...good for your health.

- Carbonated water maker: It has a refreshing feel and is suitable for drinking.

・Mineral water maker: Full-bodied and suitable for drinking.

・Soft water maker: Contains no impurities and is suitable for cooking.

It is.

Furthermore, even among water that is suitable for drinking, the water that a person desires at any given time varies depending on their physical condition and mood.

Therefore, in order to supply the water you want when you want it, it is necessary to have all the types of water generators available.In this case, problems arise in that the device becomes larger, the construction is complicated, the aesthetic appearance deteriorates, and the price is high.

The purpose of the present invention is to provide water with two or more properties (for example, activated carbon purified water, i.e., pure water, alkaline ionized water, mineral carbonated water,
To provide a water generator that allows selection of soft water (soft water, etc.) and can also supply water at an appropriate temperature.

[Means to solve the problem]

In order to achieve the above object, the present invention stores raw tap water in a water storage tank, and filters, deodorizes and sterilizes the water without sending water from the tank using a pressure pump.

Thereafter, the water passes through each functional addition device connected in parallel, is brought to an appropriate temperature by a temperature controller if necessary, and finally passes through a sterilizer again to be supplied as drinking water. However, in some cases, soft water is sent to a sterilizer without temperature control.

Hereinafter, one embodiment of the water generator of the present invention is shown in FIG. 1, and will be described in detail based on the same figure. Water supply raw water is supplied to a water storage tank 2 via an on-off valve l. The water level in the water storage tank 2 is controlled by a level sensor 21. Water in the water storage tank 2 is first sent to a filtration and deodorization device 4 via a pump 3 to remove limescale and mold odors. Next, the water is sent to the first sterilizer 5, whereby bacteria existing in the tap water and bacteria that have invaded from the tank 2 are sterilized. Sterilizer (
Although not specified, ultraviolet sterilization method (including removal equipment) 5 is not specified.
V method), a heat sterilization method, an ozone sterilization method, a sterilization method using a hollow filter, etc. are used.

The sterilized water is branched and sent to an alkaline ion water production device 6, a mineral carbonated water production device 7, a bypass pipe 8, and a soft water production device 9. The selection is for each function addition device 6 and 7.
- It is carried out by opening and closing the on-off valves 10 to 13 attached to the bypass pipe 8 or the bypass pipe 8. It should be noted that these alkaline ionized water production devices 6 and the like are those that have been commonly used in the past.

The water softening device is one in which an ion exchange resin is placed in a container, and when water is passed through it, cd′2゜M g 2
The type of water used is one that adsorbs water such as ° and produces soft water.

Here, since the bypass pipe 8 does not have any particular function added, the water obtained is only filtered and deodorized water, and is called pure water. Alkaline ionized water, mineral carbonated water, and pure water are suitable for drinking as mentioned above, so temperature controller 1
4 and adjusted to the desired temperature. Since soft water is used for cooking, the temperature regulator 1 is used as in this embodiment.
It is sent to the next process without being passed through step 5, or without intentional temperature adjustment even if it is passed through. Then the second sterilizer 1
The drinking water is sterilized again by 5 and then supplied from the drinking water supply port 17 via the on-off valve 16. The sterilizer 15 is effective when bacteria enters through the supply port 17 and ascends upstream in the piping.

Since the second sterilizer 15 passes temperature-controlled water, it is preferable to use a sterilization method that causes little temperature change, and it is generally preferable to use an ultraviolet sterilization method or an ozone sterilization method.

In addition, since the piping section from the branch section 20, which is the connection point between the temperature regulator 14, the sterilization device 15, and the water softening device 9, to the drinking water supply port 17 is a common passage section for each functional water, the piping The water that remains in the area is the functional water that was created last time, and the temperature has been raised to around room temperature.

Therefore, if you want other functional water at a lower temperature, it is necessary to discard the unnecessary water remaining in the pipes. Therefore, when drinking drinking water, first open the drain valve 18 while keeping the shut-off valve 16 closed, drain the water accumulated after the branch 20 through the drain port 19, and then open the shut-off valve 16.
8 is closed, the on-off valve 16 is opened, and the valve control is performed to supply the desired functional water from the supply port 17.

〔Effect of the invention〕

As described above, with the water generator of the present invention, required functional water can be obtained when needed.

In addition, in the water generator of the present invention, sterilization is performed at two locations in the treatment circuit, on the inlet side and the outlet side, so even if bacteria enter from the water storage tank 2 and the supply port 17, the sterilization will ensure that they are safe and harmless. Functional water is supplied.
