[Brief explanation of the drawings]

[0012] [Figure 1] 1 is a longitudinal cross-sectional view showing a hydrogen and oxygen generating device to which an embodiment of a tank according to the present invention is applied. [Figure 2] FIG. 2 is a cross-sectional view of the right side of the hydrogen and oxygen generating device shown in FIG. 1. DETAILED DESCRIPTION OF THE INVENTION

[0013] Hereinafter, an embodiment of the present invention will be described. [One embodiment of the invention] 1 and 2 show one embodiment of the present invention.

[0014] Fig. 1 is a longitudinal cross-sectional view showing a hydrogen and oxygen generating device to which an embodiment of a tank according to the present invention is applied, and Fig. 2 is a right cross-sectional view showing the hydrogen and oxygen generating device of Fig. 1.

[0015] 1 and 2, a hydrogen and oxygen generation device 1 to which the tank of this embodiment is applied has a box-shaped case 2, and a polycarbonate tank body 4 is placed inside this case 2, and an opening 4a is formed in the upper part of this tank body 4. This opening 4a is closed by a lid 3 so as to be able to open and close.

[0016] In addition to the tank body 4, the case 2 is provided with a purified water tank 5, an electrolysis unit (hereinafter referred to as an electrolysis unit) 6, and a steam-water separator 7 as main components.

[0017] The purified water tank 5 and the electrolysis unit 6 are connected via a purified water supply pipe 8. The electrolysis unit 6 electrolyzes purified water supplied from the purified water tank 5 through the purified water supply pipe 8 to generate hydrogen gas and oxygen gas in a ratio of 2:1.

[0018] The electrolysis unit 6 and the steam separator 7 are connected via a hydrogen gas / water discharge pipe 9. The hydrogen gas electrolyzed in the electrolysis unit 6 contains water, and this hydrogen gas and water are discharged through the hydrogen gas / water discharge pipe 9 to the steam separator 7, where the hydrogen gas and water are separated. The separated hydrogen gas is supplied from a hydrogen discharge port 10a of the case 2 through a hydrogen gas discharge pipe 10 to an external device, such as a hydrogen inhaler (not shown). On the other hand, the separated water returns to the purified water tank 5 through a separated water return pipe 11.

[0019] The electrolysis unit 6 and the tank body 4 are connected via an oxygen gas / water discharge pipe 12. The oxygen gas electrolyzed in the electrolysis unit 6 contains more water than hydrogen gas and water and cannot be separated by the gas-water separator 7, so the oxygen gas and water are discharged into the tank body 4 through the oxygen gas / water discharge pipe 12.

[0020] One end of a tank water return pipe 13 is connected to the bottom of the tank body 4, and the other end of this tank water return pipe 13 is connected to the purified water tank 5. Of the oxygen gas and water discharged into the tank body 4, the water returns to the purified water tank 5 through the tank water return pipe 13. The inside of the tank body 4 is sealed to prevent oxygen gas from leaking, and a high pressure (for example, 1 MPa) is applied thereto.

[0021] Near the underside of the upper surface 3a of the lid 3, there is an internal tank oxygen / hydrogen gas intake port 14a, which is one end of an oxygen gas discharge pipe 14. This oxygen gas discharge pipe 14 is arranged to pass through the inside of the tank body 4 and lead out of the tank body 4 via a pipe insertion hole 4b in the tank body 4, and the other end is connected to an oxygen discharge port 14b in the case 2. Here, the oxygen discharged into the tank body 4 is mixed with approximately 0.5 to 1.5% hydrogen gas. The oxygen gas mixed with hydrogen gas is supplied through the oxygen gas discharge pipe 14 and from the oxygen discharge port 14b in the case 2 to an external device, such as an oxygen inhaler (not shown).

[0022] 1, a water level sensor 15 is installed in the tank body 4, and this water level sensor 15 detects the upper and lower limits of the water level inside the tank body 4. When the water level inside the tank body 4 reaches the lower limit, an alarm is sounded and a message to that effect is displayed on the operation panel installed in the case 2. In this case, the lid 3 of the tank body 4 is opened to supply purified water.

[0023] An ultraviolet lamp 16 is installed inside the tank body 4, and the purified water inside the tank body 4 is constantly sterilized by the ultraviolet light emitted from this ultraviolet lamp 16.

[0024] 1, a conductive sheet 20 serving as a conductive member is attached to the outer peripheral surface of the tank body 4 of this embodiment. One end of a ground wire 21 is electrically connected to the conductive sheet 20, and the other end of the ground wire 21 is electrically connected to an earth terminal 22 of the case 2.

[0025] Next, the operation of the tank of this embodiment will be described.

[0026] The oxygen gas electrolyzed in the electrolysis unit 6 contains a large amount of water, and this oxygen gas and water are discharged into the tank body 4 through the oxygen gas / water discharge pipe 12. This oxygen gas is mixed with a small amount of hydrogen gas (0.5 to 1.5%), and due to the specific gravity of this hydrogen gas, the hydrogen gas gradually accumulates in the space 3b below the upper surface 3a of the lid 3 due to the structure of the tank body 4, and the hydrogen gas accumulates in the space 3b. If the hydrogen gas concentration exceeds 4%, a malfunction will occur.

[0027] Therefore, in this embodiment, one end of the oxygen gas exhaust pipe 14 is disposed near the underside of the upper surface 3a of the lid 3, and the oxygen gas exhaust pipe 14 is disposed so as to pass through the inside of the tank body 4 and lead out to the outside of the tank body 4. This allows hydrogen gas mixed with oxygen gas inside the tank body 4 to be effectively exhausted.

[0028] In this embodiment, one end of the oxygen gas exhaust pipe 14 is located near the underside of the upper surface 3a of the lid body 3, and hydrogen gas mixed with oxygen gas is effectively exhausted to prevent hydrogen gas from accumulating in the space 3b of the lid body 3. However, if, for example, one end of the oxygen gas exhaust pipe 14 is located in the middle part of the tank body 4 in the vertical direction, due to specific gravity, only oxygen gas will be exhausted and hydrogen gas will gradually accumulate and build up in the space 3b of the lid body 3, which is a problem.

[0029] In addition, in this embodiment, a conductive sheet 20 is attached to the outer peripheral surface of the tank body 4, and static electricity that has been charged from this conductive sheet 20 to the tank body 4 is discharged through a grounding wire 21 so that the tank body 4 is not charged.

[0030] As described above, according to this embodiment, one end of the oxygen gas exhaust pipe 14 faces near the underside of the upper surface 3a of the lid 3, and this oxygen gas exhaust pipe 14 is arranged so as to pass through the inside of the tank body 4 and lead out to the outside, so that hydrogen gas mixed with the oxygen gas that has flowed into the tank body 4 can be reliably discharged without accumulating near the underside of the upper surface 3a of the lid 3. As a result, hydrogen gas does not accumulate inside the lid 3, and safety can be improved.

[0031] Furthermore, according to this embodiment, a conductive sheet 20 is attached to the outer peripheral surface of the tank body 4, and the static electricity that has accumulated on the tank body 4 from this conductive sheet 20 is discharged through the grounding wire 21, thereby preventing the tank body 4 from becoming charged even if it is made of synthetic resin. [Another embodiment of the invention] Although an embodiment of the present invention has been described, this embodiment is presented as an example and is not intended to limit the scope of the invention. This embodiment can be embodied in various other forms, and various omissions, substitutions, modifications, and combinations can be made without departing from the spirit of the invention. This embodiment is included within the scope and spirit of the invention, as well as within the scope of the invention described in the claims and their equivalents.

[0032] In the above embodiment, the tank body 4 is made of polycarbonate, but the present invention is not limited to this and other synthetic resins such as ABS resin and polypropylene may also be used.

[0033] Furthermore, in the above embodiment, an example has been described in which the conductive sheet 20 is used as the conductive member, but the present invention is also applicable to conductive members other than sheets.

[0034] Furthermore, in the above embodiment, an example has been described in which one electrolysis unit 6 is installed in the case 2; however, the number of electrolysis units is not limited to one, and more may be installed depending on the amounts of hydrogen gas and oxygen gas generated.
