water dispenser

Abstract

The present invention provides a water dispenser capable of preventing bacteria from entering with the introduction of outside air and suppressing bacteria from multiplying in the water dispenser with a simple structure. For this reason, in water dispensers, as the air filter (1) for introducing external air, an air filter composed of a porous membrane for protection fixed on both sides of a porous membrane made of fluororesin with a pore diameter of 0.2 μm to 0.8 μm is used. In addition, in the box, there is an antibacterial member (2) that seals a plurality of granular antibacterial agents in a water-permeable porous bag. The granular antibacterial agents are made of low-density polyethylene and silver ions and zeolite. formed ion exchangers.

Description

technical field [0001] The present invention relates to a drinking water server capable of drinking water from a replaceably attached drinking water container to a cup or the like, capable of preventing the entry of bacteria and suppressing the growth of bacteria. Background technique [0002] Conventionally, drinking water dispensers have been used in workplaces and the like. In drinking water dispensers, drinking water containers are replaceably installed, and a required amount of drinking water can be taken from the containers to cups and the like when necessary. As the above drinking water container, a hard type (gallon bottle type) which does not deform is generally used. [0003] For example, if Figure 8 As shown, this water dispenser is provided with a container connecting portion 11 connected to the mouth of the above-mentioned drinking water container B in a freely detachable manner. cold water tank 12 and hot water tank 13 for drinking water, and are provided wit...

AI Technical Summary

Problems solved by technology

[0014] However, the piping system of the above-mentioned water dispenser with a heating device is extremely complicated, and not only the water dispenser itself is expensive, but also has problems such as increased power consumption, high running costs, and problems such as the fact that the water dispenser cannot be used while the heating device is in operation.

In addition, drinking fountains equipped with ultraviolet lamps have problems that ultraviolet rays are harmful to the human body and eyeballs, and ultraviolet rays cause deterioration of resin parts and rubber parts in the drinking fountains, etc.

In addition, in a water dispenser with an ozone generator, since ozone gas is not useful to the human body, there are problems such as restrictions on the concentration of ozone gas, problems that ozone has a unique odor and impairs the taste of drinking water, etc.

In addition, since a water dispenser equipped with a plasma generator and other sterilizing devices operates multiple sterilizing devices at the same time, there are problems such as large energy consumption and extremely complicated devices.
