The electrolysis unit 1 electrolyzes a liquid. The elastic body 2 is formed by stacking the electrolysis units 1. The elastic body 2 has a hollow portion 211 (see Fig. 3) and a blocking wall 2111 (see Fig. 3). The hollow portion (211) is formed along a first direction D1, which is the stacking direction of the electrolysis unit 1 and the elastic body 2.

[0013] In the electrolytic liquid generating apparatus 100 according to the first embodiment, the hollow portion 211 is provided in the elastic body 2 along the first direction D1, which is the lamination direction of the electrolysis section 1 and the elastic body 2, so that it is possible to uniformize the compressive stress of the elastic body 2 in the first direction D1. In addition, since a blocking wall 2111 is provided in a part of the hollow portion 211 in the first direction D1, it is possible to increase the rigidity of the elastic body 2 in the first direction D1. In other words, according to the electrolytic liquid generating apparatus 100 according to the first embodiment, it is possible to increase the rigidity of the elastic body 2 while uniformizing the compressive stress of the elastic body 2.

[0014] (2)Details Next, the details of the electrolytic liquid generating device 100 according to the first embodiment will be described with reference to Figs. 1 to 3. In the following description, the longitudinal direction of the electrode pins 41 described later, i.e., the lamination direction of the electrolytic section 1, is defined as a first direction D1, the longitudinal direction of the housing 3 described later, i.e., the electrolyte flow direction (or flow path direction) is defined as a second direction D2, and the short side direction (width direction) of the housing 3 is defined as a third direction D3. However, these directions are not intended to limit the directions in which the electrolytic liquid generating device 100 is used.

As shown in FIG. 1, the electrolysis unit 1 includes a cathode 11, a conductive film 12, and an anode 13.

[0017] The cathode 11 is formed of, for example, a titanium alloy in a rectangular plate shape having a thickness of about 0.3 mm. More specifically, the cathode 11 is formed in a rectangular plate shape that is longer in the second direction D2 than in the third direction D3. The cathode 11 has a plurality of through holes 111. Each of the plurality of through holes 111 penetrates the cathode 11 in a thickness direction (first direction D1). Each of the plurality of through holes 111 is formed in a V shape in a plan view from the first direction D1. The plurality of through holes 111 are arranged at equal intervals along the longitudinal direction (second direction D2) of the cathode 11. At one end (the right end in FIG. 1) of the cathode 11 in the second direction D2, an electrode plate 42A is integrally formed via a spring portion 43A, as described later.

[0018] The conductive film 12 is, for example, a proton conductive ion exchange filter having a thickness of about 100 to 200 μm. As shown in FIG. 1, the conductive film 12 is formed in a comb shape when viewed from a plane in the first direction D1.

The plurality of protruding pieces 122 are arranged at equal intervals along the second direction D2.

[0019] The anode 13 is formed, for example, by forming a conductive diamond film on a conductive substrate made of silicon. The anode 13 is formed in a rectangular plate shape that is longer in the second direction D2 than in the third direction D3, as shown in Fig. 1. In this embodiment, the cathode 11, the conductive film 12, and the anode 13 form a laminate in which the anode 13, the conductive film 12, and the cathode 11 are stacked in this order in the first direction D1.

[0020] (2.2) Elastic body The elastic body 2 is formed into a rectangular parallelepiped shape using an elastic material such as rubber, etc. As shown in Figures 1 and 2, the elastic body 2 includes a main body 21, a plurality of (six in the illustrated example) first positioning parts 22, and a plurality of (two in the illustrated example) second positioning parts 23.

[0021] As shown in Fig. 2, the main body 21 is formed in a rectangular parallelepiped shape that is longer in the second direction D2 than in the third direction D3. That is, the elastic body 2 is elongated in the second direction D2 that is perpendicular to the first direction D1, which is the stacking direction of the electrolysis unit 1 and the elastic body 2. The main body 21 has an upper surface 212 on which the electrolysis unit 1 is stacked. The upper surface 212 is formed in a rectangular shape that is longer in the second direction D2 than in the third direction D3 in a plan view from the first direction D1. That is, the elastic body 2 has an upper surface 212 on which the electrolysis unit 1 is stacked.

[0022] As shown in FIG. 3, the main body 21 has a plurality of hollow portions 211. Each of the plurality of hollow portions 211 is formed along the first direction D1. That is, the elastic body 2 has a plurality of hollow portions 211 formed along the stacking direction (first direction D1) of the electrolysis unit 1 and the elastic body 2. The plurality of hollow portions 211 are arranged along the second direction D2, which is the longitudinal direction of the elastic body 2. The shapes of the plurality of hollow portions 211 may be the same or different. In the example of FIG. 3, the shapes of some of the hollow portions 211 (the hollow portion 211 at the left end and the second hollow portion 211 from the right in FIG. 3) are different from the shapes of the remaining hollow portions 211.

[0023] Each of the plurality of hollow portions 211 has a blocking wall 2111. That is, in this embodiment, the blocking wall 2111 is provided in all of the plurality of hollow portions 211. Each blocking wall 2111 blocks the hollow portion 211 in a part of the hollow portion 211 in the stacking direction (first direction D1) of the electrolysis unit 1 and the elastic body 2. That is, the elastic body 2 has a blocking wall 2111 that closes the hollow portion 211 in a part of the stacking direction. Also, in this embodiment, each blocking wall 2111 is provided at one end (upper end in FIG. 3) of the hollow portion 211 in the first direction D1. That is, each blocking wall 2111 is a part of the upper surface 212.

As an example, the height L1 of the elastic body 2 is 6.4 mm, and the thickness L2 of each blocking wall 2111 is 0.4 mm. In this manner, by setting the thickness L2 of each blocking wall 2111 within the above range, it is possible to reduce the weight of the elastic body 2 while increasing the rigidity of the elastic body 2.

The remaining three of the six first positioning parts 22 are arranged at equal intervals along the second direction D2 on the other end side of the upper surface 212 in the third direction D3. Furthermore, the six first positioning parts 22 are arranged on the outside of the upper surface 212 in the third direction D3. Each of the multiple first positioning parts 22 includes a protruding part that protrudes along the first direction D1.

More specifically, the two second positioning parts 23 are arranged on the outer side of the upper surface 212 in the second direction D2. One of the two second positioning parts 23 is arranged almost in the center in the third direction D3. The other of the two second positioning parts 23 is arranged on one end side in the third direction D3. In this way, by making the positions of the two second positioning parts 23 different in the third direction D3, it is possible to reduce installation errors of the elastic body 2 to the case 31 of the housing 3. Each of the second positioning parts 23 includes a protruding part that protrudes along the first direction D1. In this way, by providing the second positioning parts 23, it is possible to position the electrolysis unit 1 in the second direction D2 with respect to the elastic body 2.

In addition, since a blocking wall 2111 is provided in a part of the hollow portion 211 in the first direction D1, it is possible to increase the rigidity of the elastic body 2 in the first direction D1. In other words, according to the electrolytic liquid generating apparatus 100 according to the first embodiment, it is possible to increase the rigidity of the elastic body 2 while uniformizing the compressive stress of the elastic body 2.

[0040] In the electrolytic liquid generating apparatus 100 according to the first embodiment, the blocking wall 2111 is a part of the upper surface 212.

[0041] Moreover, in the electrolytic liquid generating apparatus 100 according to the first embodiment, all of the hollow portions 211 are provided with blocking walls 2111.

The main body 21 has an upper surface 212 on which the electrolysis unit 1 is stacked. The upper surface 212 is formed in a rectangular shape that is longer in the second direction D2 than in the third direction D3 in a plan view from the first direction D1.

In this way, by setting the thickness L2 of each blocking wall 2111 within the above range, it is possible to reduce the weight of the elastic body 2A while increasing the rigidity of the elastic body 2A.

[0056] In the electrolytic liquid generation apparatus 100 according to the second embodiment, similarly to the electrolytic liquid generation apparatus 100 according to the first embodiment, it is possible to increase the rigidity of the elastic body 2A while making the compressive stress of the elastic body 2A uniform.

[0057] (Aspect) The present specification discloses the following aspects.

[0058] The electrolytic liquid generating device (100) according to the first aspect includes an electrolysis section (1) and an elastic body (2; 2A). The electrolysis section (1) electrolyzes a liquid. The elastic body (2; 2A) is formed by stacking electrolysis sections (1). The elastic body (2; 2A) has a hollow section (211; 211A) and a blocking wall (2111). The hollow section (211; 211A) is formed along a stacking direction (D1) of the electrolysis section (1) and the elastic body (2; 2A). The blocking wall (2111) partially closes the hollow section (211; 211A) in the stacking direction (D1).

[0059] According to this aspect, by providing a hollow portion (211; 211A) along the first direction (D1) in the elastic body (2; 2A), it is possible to uniformize the compressive stress of the elastic body (2; 2A) in the first direction (D1). Also, according to this aspect, by providing a blocking wall (2111) in a part of the hollow portion (211; 211A) in the first direction (D1), it is possible to increase the rigidity of the elastic body (2; 2A) in the first direction (D1). That is, according to this aspect, it is possible to increase the rigidity of the elastic body (2; 2A) while uniformizing the compressive stress of the elastic body (2; 2A).

[0060] In the electrolytic liquid generation device (100) according to the second aspect, in the first aspect, the elastic body (2; 2A) has an upper surface (212) on which the electrolytic section (1) is laminated. The blocking wall (2111) is a part of the upper surface (212).

[0061] According to this embodiment, the occurrence of burrs during molding can be suppressed, and it is therefore possible to suppress a decrease in assembly accuracy due to burrs getting caught when stacking the electrolysis section (1) on the upper surface (212) of the elastic body (2; 2A).

[0062] In the electrolytic liquid generation device (100) according to the third aspect, in the first or second aspect, the elastic body (2; 2A) has a plurality of hollow portions (211; 211A). At least one of the plurality of hollow portions (211; 211A) is provided with a blocking wall (2111).

[0063] According to this embodiment, it is possible to increase the rigidity of the elastic body (2; 2A) in the first direction (D1).

[0064] In the electrolytic liquid generation device (100) according to the fourth aspect, in the third aspect, the elastic body (2; 2A) is elongated in a second direction (D2) perpendicular to the first direction (D1) which is the stacking direction, and the hollow portions (211; 211A) are aligned along the second direction (D2).

[0065] According to this embodiment, it is possible to increase the rigidity in the first direction (D1) over the entire length of the elastic body (2; 2A).

[0066] In the electrolytic liquid generation apparatus (100) according to the fifth aspect, in any one of the first to fourth aspects, the percentage of the thickness (L2) of the blocking wall (2111) in the arrangement direction (D1) relative to the length (L1) of the elastic body (2; 2A) in the stacking direction (D1) is 5% or more and 10% or less.

[0067] According to this embodiment, it is possible to reduce the weight of the elastic body (2) while increasing the rigidity of the elastic body (2).

[0068] The electrolytic liquid generating device (100) according to a sixth aspect is any one of the first to fifth aspects, and further includes a housing (3). The housing (3) has an electrolytic unit (1) and an elastic body (2; 2A) disposed therein. The housing (3) includes a case (31) and a lid (32). The case (31) has an opening (3111), and the electrolytic unit (1) and the elastic body (2; 2A) are accommodated through the opening (3111). The lid (32) is attached to the case (31) so as to close the opening (3111) of the case (31). The lid (32) holds the electrolytic unit (1) between the elastic body (2; 2A) and the lid (32) when the lid (32) is attached to the case (31).

[0069] According to this embodiment, the elastic force from the elastic body (2; 2A) makes it possible to bring the electrolysis section (1) into close contact with the elastic body (2; 2A) and the cover body (32).

[0070] The configurations according to the second to sixth aspects are not essential for the electrolytic liquid generation device (100) and may be omitted as appropriate. [Explanation of symbols]
