Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The drinking water producing apparatus according to the present embodiment is for producing produced water in the apparatus by cooling air and condensing moisture in the air, and purifying the produced water to produce drinking water. Then, as shown in FIG. 1, the apparatus main body 1, the water generation means 3, the storage means 4, the lead-out flow path 5, the purification means 7, the ozone generation means 9, the introduction flow path 11, and the ozone It mainly comprises the pump 10 and the check valve 12.

The apparatus main body 1 constitutes the casing of the present drinking water generating apparatus, and various means (water generating means 3, purification means 7, ozone generating means 9, etc.), parts and pipes (ozone pump 10, lead-out etc.) inside The flow path 5 etc. is disposed. A fan 2 for forcibly introducing outside air into the inside of the apparatus is formed at a predetermined position of the apparatus main body 1, and the fan 2 is configured to be able to cool the outside air while supplying the water generating means 3 with the outside air. It is preferable to dispose a filter or the like capable of capturing and removing foreign substances contained in the outside air (air) introduced by the fan 2.

The water generation means 3 can obtain the generated water by condensing moisture in the air in the apparatus main body 1, and it is possible to use, for example, a metal part having fins 3a formed on the back side. it can. That is, air is introduced to the water generation means 3 by the fan 2 and the air is cooled by the air flow of the fan 2 and the cooling action of the fins 3a, so that water contained in the air is condensed to be efficiently generated. You can get water. In addition, as long as it can cool the air and condense the moisture in the air to obtain the generated water, the water generation means 3 may be another form.

The generated water produced by the water producing means 3 is supplied to the containing means 4 disposed below. The storage means 4 comprises a tank or the like capable of storing a predetermined amount of generated water obtained by the water generation means 3. In the present embodiment, the detection means 13 capable of detecting the liquid level of the stored generated water is used. It is attached. The detection means 13 is, for example, a mechanical type or a sensor that utilizes floating buoyancy (a type that detects liquid level by irradiating light or sound wave to generated water and detecting light or sound wave reflected or transmitted, etc.) It may be in any form, such as one using.

Further, at the bottom surface of the housing means 4, a lead-out flow passage 5 composed of a pipe, a tube or the like is connected.

However, at normal times, the lead-out pump 6 is in the stop state, and the solenoid valve 8 is in the closed state (the lead-out flow path 5 is blocked).

Then, when the operating means 14 including, for example, an operation button and a lever attached to the front or side of the apparatus body 1 is operated, the solenoid valve 8 is opened (in a state where the outlet channel 5 is released) Since the pump 6 is driven, the generated water stored in the storage means 4 flows through the outlet channel 5 and is discharged from the discharge port 5a. It should be noted that the discharge pump 6 may not be provided, and when the solenoid valve 8 is in the open state, the drinking water may be discharged from the discharge port 5a by its own weight or the solenoid valve 8 is not provided and it is not driven It is also possible to use a lead-out pump 6 that can block the flow path and allow generated water to flow by driving.

In this case, part of the oxygen molecule is dissociated into two oxygen atoms by the action of accelerated electrons by the discharge, and the dissociated oxygen atom reacts with other oxygen molecules to generate ozone.

The ozone generation means 9 may be another form different from the discharge method, for example, one capable of generating ozone by a photochemical method using an ultraviolet lamp, one capable of generating ozone by an electrolysis method using electrolysis, It is good also as a thing etc. which can produce ozone by the activated carbon adsorption decomposition method to which it carries out adsorption decomposition using. The ozone generated by the ozone generating means 9 acts on microbes (bacteria, fungi, etc.) and odor substances to be capable of decolorization of pigments in addition to sterilization and deodorization.

The introduction channel 11 comprises a channel such as a pipe or a tube that connects the ozone generation unit 9 and the storage unit 4, supplies the ozone generated by the ozone generation unit 9 to the storage unit 4, and supplies the ozone to the storage unit 4.

That is, as shown in FIG. 2, the introduction channel 11 is disposed such that the discharge port 11 a at the tip is positioned in the vicinity of the bottom surface of the storage unit 4, and the ozone generated by the ozone generation unit 9 is a discharge port. It is constituted so that it may be spouted from generated water stored in storage means 4 by being discharged from 11a.

Thus, the ozone jetted from the discharge port 11a becomes bubbles in the generated water and flows upward, and the generated water can be disinfected and disinfected in the process. Note that, as shown in FIG. 3, the introduction flow passage 11 may be configured such that a plurality of discharge ports 11 b are formed at the tip thereof and ozone is jetted from each discharge port 11 b. In this case, ozone can be supplied and jetted over substantially the entire region of the containing means 4, and the sterilizing effect can be further improved.
