For example, the size and thickness of each component shown in the drawings are arbitrarily shown for the sake of convenience of explanation, and the present invention is not necessarily limited to those shown in the drawings.

[0022] In the following embodiments, the x-axis, y-axis, and z-axis are not limited to the three axes on a Cartesian coordinate system, but can be interpreted in a broad sense including them. For example, the x-axis, y-axis, and z-axis may be orthogonal to each other, or may point in different directions that are not orthogonal to each other.

[0024] FIG. 1 is a schematic diagram showing an electrode-based heating device according to one embodiment of the present invention, FIG. 2 is an exemplary enlarged view of A in FIG. 1, and FIG. 3 is a cross-sectional view taken along line III-III in FIG. 1.

[0025] 1 to 3, the electrode-based heating device 100 of this embodiment may include a main body portion 120 and a heating unit portion HU.

[0026] The body 120 may be configured to have a fluid WT disposed inside it. The fluid WT may include various types, such as a liquid or a gas.

[0027] In an alternative embodiment, the fluid WT may include water, and for example, the electrode-based heating device 100 may include a method that utilizes heated water.

[0028] The body 120 can have a variety of shapes, for example, a hollow box shape.

[0029] In alternative embodiments, the main body 120 may have a columnar shape, for example a shape similar to a cylinder, or as another example, a rectangular prism shape, or as another example, a columnar shape having a curved base similar to an ellipse.

[0030] In an optional embodiment, the main body portion 120 can be formed to be longer than the heating unit portions HU1 and HU2.

[0031] For example, the fluid WT inside the main body 120 can correspond to the side surfaces of the heating units HU1 and HU2, and as a specific example, can be arranged so as to surround the side surfaces.

[0032] The fluid WT can be disposed between the first heating unit HU1 and the second heating unit HU2 of the heating unit section HU.

[0033] With such a configuration of the main body 120, the fluid WT inside the main body 120 can be easily heated via the heating unit HU.

[0034] The main body 120 may have various shapes and may include at least an inlet 121 for the inflow of the fluid WT and an outlet 122 for the discharge of the fluid WT.

[0035] Specifically, an unheated fluid CW before heating can be introduced through the inlet 121, and for example, the unheated fluid CW may include water at room temperature or low temperature.

[0036] The heated fluid HW can be discharged via the outlet 122, for example heated water.

[0037] As a specific example, unheated fluid CW containing water at room temperature flows in through the inlet 121, flows into the main body 120, and is then heated through the heating unit HU, and the heated fluid HW containing such heated water can be discharged through the outlet 122.

[0038] In an optional embodiment, the inlet 121 and the outlet 122 may be disposed on either side of the heating unit HU, such that the fluid WT flowing in through the inlet 121 passes through spaces adjacent to the first heating unit HU1 and the second heating unit HU2 of the heating unit HU, thereby improving heating efficiency.

[0039] The body 120 can be formed from a variety of materials. For example, the body 120 can be formed from a durable, lightweight insulating material. In alternative embodiments, the body 120 can be formed from a plastic material, including various resin families. In other alternative embodiments, the body 120 can include an inorganic material, such as a ceramic.

[0040] Additionally, in other alternative embodiments, the body portion 120 may be formed from a metallic material.

[0041] As another example, the main body 120 may include Teflon resin, which is a fluororesin.

[0042] In an optional embodiment, at least the inner surface of the main body portion 120 adjacent to the fluid WT may include an insulating layer, which may include, for example, an inorganic layer, and may contain inorganic materials including ceramic.

[0043] As another example, an insulating layer containing an organic substance may be formed on the inner surface of the main body 120 that is adjacent to the fluid WT.

[0044] This improves the mutual insulation characteristics with the heating unit part HU, and improves safety when using the electrode-based heating device 100.

[0045] The heating unit section HU may include at least a plurality of heating units HU1 and HU2, and may include, for example, a first heating unit HU1 and a second heating unit HU2.

[0046] In an alternative embodiment, the first heating unit HU1 and the second heating unit HU2 can be arranged to be spaced apart from each other.

[0047] Electrolyzed water IW may be disposed inside the first heating unit HU1, and may be disposed so as to be separated from the fluid WT outside.

[0048] For example, the electrolyzed water IW may be disposed inside the heat dissipation section 130 of the first heating unit HU1, or may be disposed so as to distinguish the electrolyzed water IW from the fluid WT via the heat dissipation section 130. A more detailed description of the heat dissipation section 130 will be given later.

[0049] The electrolyzed water IW may be of various types. For example, the electrolyzed water IW may contain an electrolyte solution, and specific examples thereof may include distilled water, filtered water, mineral water, tap water, etc., in which one or more of various types of electrolyte solutions have been appropriately diluted.

[0050] The electrolyte substances contained in the electrolyzed water IW may be of various types, including inorganic substances such as edible soda, phosphates, nitrates, salts, silicates, and polyphosphates, as well as rust inhibitors whose main components are amines and oxyacids.

[0051] The first heating unit HU1 may have a shape that controls the inflow and outflow of electrolyzed water IW, and may be formed so that the electrolyzed water IW does not flow out after being filled inside the first heating unit HU1. As another example, the first heating unit HU1 may include a refill inlet (not shown) for refilling or discharging the electrolyzed water IW.

[0052] Meanwhile, the area of ​​the first heating unit HU1 that comes into contact with the electrolyzed water IW can be made of various materials, including a durable, lightweight insulating material, or, in another optional embodiment, a metal material.

[0053] In an optional embodiment, the area of ​​the first heating unit HU1 that comes into contact with the electrolyzed water IW may include an insulating layer, for example, may include an inorganic layer, or may contain an inorganic material including ceramic.

[0054] As another example, the area of ​​the first heating unit HU1 that comes into contact with the electrolyzed water IW may include a Teflon resin layer, which is a fluororesin.

[0055] The first heating unit HU1 can include an electrode section 160 having one or more electrodes.

[0056] At least one region of the electrode portion 160 may be disposed inside the first heating unit HU1, for example, inside the heat dissipation portion 130.

[0057] In addition, the electrode unit 160 can be arranged so as to overlap the electrolyzed water IW so as to heat the electrolyzed water IW in the inner region of the heat dissipation unit 130.

[0058] In addition, the electrode unit 160 may overlap the fluid WT disposed inside the body unit 120 in one direction.

[0059] The electrode section 160 may include multiple electrodes.

[0060] For example, the electrode unit 160 may include a first electrode 161 and a second electrode 162.

[0061] As a specific example, the first electrode 161 and the second electrode 162 may be formed to be in contact with the electrolyzed water IW. Although not shown, an electrode control unit (not shown) may apply a current to the first electrode 161 and the second electrode 162, and the control unit (not shown) may control the current.

[0062] In an optional embodiment, the first electrode 161 and the second electrode 162 may include a first terminal portion 161T and a second terminal portion 162T, respectively, and a power source may be connected via the first terminal portion 161T and the second terminal portion 162T.

[0063] The electrolyzed water IW can be heated by the current applied to the first electrode 161 and the second electrode 162 of the electrode unit 160. The heat generated by the heating of the electrolyzed water IW is transferred to the fluid WT in the main body unit 120, thereby heating the fluid WT.

[0064] The first electrode 161 and the second electrode 162 may be spaced apart from each other in the inner space of the first heating unit HU1.

[0065] For example, the first electrode 161 and the second electrode 162 may have a long, elongated shape spaced apart from each other in the inner space of the heat dissipation part 130 of the first heating unit HU1, or may have a linear shape.

[0066] One end portion of each of the first electrode 161 and the second electrode 162 extending from the heat dissipation unit 130 may be spaced apart from a region, for example, an inner surface of the heat dissipation unit 130. For example, each end portion extending in a direction opposite to the first terminal portion 161T and the second terminal portion 162T may be spaced apart from the inner surface of the heat dissipation unit 130.

[0067] This allows the heating process of the electrolyzed water IW to proceed stably while reducing the occurrence of electrical leakage, short circuits, etc. within the heat dissipation section 130.

[0068] In addition, the first electrode 161 and the second electrode 162 may include a conductive portion (not shown) connected to a region thereof, for example, the first terminal portion 161T and the second terminal portion 162T, so that a current is applied to the first electrode 161 and the second electrode 162, and such a conductive portion (not shown) may be connected to an electrode control portion (not shown) as a wire-shaped conductor.

[0069] In another alternative embodiment, the electrode section 160 may include three electrodes in a three-phase configuration.

[0070] In an optional embodiment, a temperature sensing member (not shown) may be further disposed to measure the temperature of the electrolyzed water IW inside the heat dissipation unit 130. Also, a cooling unit (not shown) may be further disposed to control overheating of the temperature sensing unit (not shown).

[0071] The control unit (not shown) may be configured to control the current applied to the electrode unit 160. The current applied to each of the first electrode 161 and the second electrode 162 of the electrode unit 160 may be controlled via the control unit (not shown), and in an optional embodiment, real-time control may be performed.

[0072] At this time, the control unit (not shown) checks the amount of current applied to the electrode unit 160 and controls the current by increasing or decreasing it according to the set value, thereby reducing sudden temperature changes in the electrolyzed water IW.

[0073] The control unit (not shown) can have various forms to facilitate changing the current, for example, it may include various types of switches, or it may include a contactless relay such as a solid state relay (SSR) for sensitive and rapid control.

[0074] The heat dissipation unit 130 of the first heating unit HU1 may be disposed to distinguish between the electrolyzed water IW and the fluid WT. For example, the heat dissipation unit 130 may be located between the electrolyzed water IW and the fluid WT. The heat dissipation unit 130 may also be formed to be spaced apart from the electrode unit 160.

[0075] For example, the heat dissipation part 130 may have an elongated shape having a length based on the same direction as the longitudinal direction of the main body part 120, and as a specific example, one end of the heat dissipation part 130 may be separated from the inner surface of the main body part 120, and the fluid WT may be disposed in such a spaced area.

[0076] One side of the heat dissipation unit 130 may be connected to the body unit 120. The first terminal unit 161T and the second terminal unit 162T of the electrode unit 160 may easily extend in the direction of the side of the heat dissipation unit 130 connected to the body unit 120.

[0077] In an optional embodiment, the heat sink 130 may include a bottom surface, which may be in close contact with one side of the body 120 .

[0078] In an alternative embodiment, the heat dissipation unit 130 may have a hollow pillar shape. For example, the heat dissipation unit 130 may have a curved outer surface, specifically a cylindrical shape. This increases the contact area with the fluid WT, thereby improving the efficiency of heat transfer to the fluid WT. In addition, by having a curved outer surface that contacts the fluid WT, the fluid WT can move smoothly along the outer surface of the heat dissipation unit 130 within the interior space of the main body 120, improving the heating uniformity of the fluid WT.

[0079] In an optional embodiment, the heat dissipation portion 130 can be in contact with the electrolyzed water IW.

[0080] In an optional embodiment, the heat sink 130 may be in contact with the fluid WT.

[0081] The heat dissipation unit 130 can be made of a material with high thermal conductivity, and may be made to include, for example, a metal material. The heat of the electrolyzed water IW can be easily transferred to the fluid WT via the heat dissipation unit 130.

[0082] As examples, the heat sink 130 may include iron, aluminum, stainless steel, or other alloys.

[0083] In addition, in an optional embodiment, the heat dissipation unit 130 may include an insulating layer (not shown) on one side facing the electrolyzed water IW, or as another example, may include an insulating layer (not shown) on one side facing the fluid WT, thereby reducing or preventing current from flowing from the electrolyzed water IW to the heat dissipation unit 130.

[0084] The heat dissipation unit 130 surrounds an area in which the electrolyzed water IW is placed, and can thus be formed to surround the outside of the area in which the electrolyzed water IW is placed.

[0085] In addition, the fluid WT may be disposed outside the heat dissipation part 130 so as to surround the heat dissipation part 130 .

[0086] FIG. 2 is an exemplary enlarged view of A in FIG.

[0087] In an optional embodiment, referring to FIG. 2, the heat dissipation unit 130 may include a first insulating layer IIL1 on a side facing the electrolyzed water IW and a second insulating layer IIL2 on a side facing the fluid WT.

[0088] In addition, in an optional embodiment, at least the heat dissipation portion 130 may include only the first insulating layer IIL1 on the side facing the electrolyzed water IW.

[0089] The first insulating layer IIL1 or the second insulating layer IIL2 may include an inorganic layer such as a ceramic material.

[0090] As another example, the first insulating layer IIL1 or the second insulating layer IIL2 may include an organic layer such as a resin layer, and may specifically include an insulating Teflon layer.

[0091] The first insulating layer IIL1 reduces current flow to the heat dissipation unit 130 via the electrolyzed water IW, and can reduce or prevent such leakage current from remaining in the main body 120 or the fluid WT. Furthermore, if a leakage current component remains in the heat dissipation unit 130, the first insulating layer IIL1 reduces or prevents it from flowing into the fluid WT, thereby reducing the occurrence of electrical accidents that may occur during the flow of the fluid WT.

[0092] The electrolyzed water IW may be disposed inside the second heating unit HU2 so as to be separated from the fluid WT outside.

[0093] For example, the electrolyzed water IW may be placed inside the heat dissipation section 130 of the second heating unit HU2.

[0094] The second heating unit HU2 may include an electrode section 160 having one or more electrodes. The electrode section 160 may include a plurality of electrodes.

[0095] For example, the electrode unit 160 may include a first electrode 161 and a second electrode 162.

[0096] The contents of the electrolyzed water IW, heat dissipation section 130, and electrode section 160 of the second heating unit HU2 may be the same as the configuration of the first heating unit HU1 described above, and as another example, some of the configuration of the first heating unit HU1 can be selectively modified as needed and applied, so further detailed explanations will be omitted.

[0097] The electrode-based heating device of this embodiment may include a heating unit section including a fluid disposed inside a main body section and a plurality of heating units arranged so as to overlap the fluid in at least one region. For example, although the heating unit section has been described as including two heating units, it may include three or more heating units as needed.

[0098] The plurality of heating units are arranged to be spaced apart from each other, and the fluid overlaps with the outer surfaces of the plurality of heating units, so that the fluid can be easily heated by the heating units. The fluid can also be arranged between the plurality of heating units, so that the heating efficiency of the fluid can be improved.

[0099] As a specific example, multiple heating units are arranged at a distance between the area where the fluid flows in and the area where it is discharged from the main body, and after the fluid flows into the main body, it is heated as it flows along the sides of each of the multiple heating units and the spaces between them, thereby efficiently improving the heating rate of the fluid and the heating uniformity of the fluid within the main body.

[0100] Meanwhile, each heating unit of the heating unit section can heat the electrolyzed water by controlling the current applied to the electrodes of the electrode section, and the heat of the electrolyzed water can be transferred to the fluid via the heat dissipation section to heat the fluid, thereby allowing the heat of the electrolyzed water to be safely transferred to the fluid.

[0101] In addition, in an optional embodiment, the fluid is arranged inside the main body so as to surround the outside of each heating unit, allowing the fluid to easily move around the outside of the heating units inside the main body; as a specific example, the outer surface of the heating unit may include a curved surface, making it easy to achieve smooth fluid flow.

[0102] The smooth circulation of the heated fluid from the incoming unheated fluid improves the overall efficiency of the electrode-based heating device and improves user convenience, such as providing hot water to the user.

[0103] Furthermore, by including an insulating layer, such as an inorganic insulating layer made of ceramic, on the side of the heat dissipation unit facing the electrolyzed water, it is possible to reduce or prevent the occurrence of current flow or leakage current flow from the electrolyzed water to the heat dissipation unit, and it is also possible to improve the stability of use for the user.

[0104] 4 to 7 are cross-sectional views schematically showing various modified examples of the heating unit according to one embodiment of the present invention.

[0105] Although Figures 4 to 7 show the first heating unit HU1, this is for convenience of explanation, and the configurations of Figures 4 to 7 may be selectively applied to either the first heating unit HU1 or the second heating unit HU2, or may be applied to both.

[0106] Referring to Figure 4, as one modified example, the heat dissipation section 130' of the first heating unit HU1 may include a first insulating layer 131' and a heat dissipation member 132', and specifically, the first insulating layer 131' may be disposed on the side facing the electrolyzed water IW, and the heat dissipation member 132' may be formed on the first insulating layer 131'.

[0107] Although not shown, a second insulating layer (not shown) may be formed on the side surface facing the fluid WT, for example, on the heat dissipation member 132'.

[0108] The heat dissipation member 132' may be made of a material with high thermal conductivity, such as a metal material. As a specific example, the heat dissipation member 132' may include iron, aluminum, stainless steel, or other alloys.

[0109] With this structure, the heat of the electrolyzed water IW heated through the first electrode 161' and the second electrode 162' of the electrode unit 160' is effectively transferred to the heat dissipation unit 130', improving the efficiency of heat transfer from the heat dissipation unit 130' to the fluid. Also, abnormal leakage of current through the heat dissipation unit 130' can be blocked.

[0110] Referring to FIG. 5, as a modified example, the heat dissipation part 130'' of the first heating unit HU1 may include a base 131'' and a heat dissipation protrusion 132''.

[0111] The base 131'' may be formed in a shape that surrounds the electrolyzed water IW, and may have a shape similar to a cylinder, for example. The base 131'' may also be formed to face the electrode unit 160''.

[0112] The heat dissipation protrusions 132'' may be provided in plural and may be connected to the base 131'' and protrude from the base 131'' toward the fluid.

[0113] The heat transfer efficiency from the heat dissipation portion 130'' to the fluid can be improved via the plurality of heat dissipation protrusions 132''.

[0114] In an alternative embodiment, each of the plurality of heat dissipation protrusions 132'' may have a shape that extends in one direction and may have regions that are spaced apart from each other.

[0115] In an optional embodiment, each of the plurality of heat dissipation protrusions 132'' may have a shape extending elongated along the longitudinal direction of the heat dissipation portion 130'', and may have a length in a direction parallel to the longitudinal direction of the heat dissipation portion 130'', for example, the longitudinal direction of the base 131''.

[0116] As another example, each of the plurality of heat dissipation protrusions 132'' may have a length in a direction that is not parallel to the longitudinal direction of the base portion 131'', but that forms an acute or obtuse angle with the longitudinal direction of the base portion 131''.

[0117] As another example, each of the plurality of heat dissipation protrusions 132'' may be formed to be curved relative to the longitudinal direction of the base 131''.

[0118] The heat dissipation section 130'' can be formed from a material with high thermal conductivity, and may be formed to include, for example, a metal material. The heat of the electrolyzed water IW can be easily transferred to the fluid WT via the heat dissipation section 130''.

[0119] As examples, the heat sink 130'' may include iron, aluminum, stainless steel, or other alloys.

[0120] In addition, in an optional embodiment, the heat dissipation unit 130" may include an insulating layer (not shown) on one side facing the electrolyzed water IW, or as another example, may include an insulating layer (not shown) on one side facing the fluid WT. This can reduce or prevent current from flowing from the electrolyzed water IW through the heat dissipation unit 130".

[0121] Referring to FIG. 6, as a modified example, the heat dissipation part 1130 of the first heating unit HU1 may include a base 1131 and a heat dissipation protrusion 1132.

[0122] The base 1131 may be formed in a shape that surrounds the area where the electrode unit 1160 is disposed, and may have a shape similar to a cylinder, for example. The base 1131 may also have a shape that surrounds the electrolyzed water IW.

[0123] The heat dissipation protrusions 1132 may be provided in plural, and may be connected to the base 1131 and protrude from the base 1131 toward the fluid.

[0124] Each of the heat dissipation protrusions 1132 may be inclined with respect to the outer circumferential surface of the base 1131. For example, each of the heat dissipation protrusions 1132 may be formed to have an acute angle or an obtuse angle with respect to the outer circumferential surface of the base 1131.

[0125] As a specific example, when each of the plurality of heat dissipation protrusions 1132 is inclined with respect to the outer circumferential surface of the base 1131, the heat dissipation protrusions 1132 may be inclined in the same direction. For example, as shown in FIG. 6, the heat dissipation protrusions 1132 may be inclined counterclockwise with respect to the outer circumferential surface of the base 1131.

[0126] This structure allows smooth heat exchange between the heat dissipation protrusion 1132 and the fluid.

[0127] In addition, the fluid can flow along the inclined direction of the heat dissipation protrusions 1132, and the fluid can easily move within the inner space of the main body, improving the uniformity of heating.

[0128] Referring to FIG. 7, as a modified example, the heat dissipation part 1130' of the first heating unit HU1 may include a base 1131' and a heat dissipation protrusion 1132'.

[0129] The base 1131′ may be formed in a shape that surrounds the area where the electrode unit 1160′ is disposed, and may have a shape similar to a cylinder, for example. The base 1131′ may also have a shape that surrounds the area where the electrolyzed water IW is disposed.

[0130] The heat dissipation protrusions 1132' may be provided in plural, and may be connected to the base 1131' and protrude from the base 1131' toward the fluid.

[0131] Each of the plurality of heat dissipation protrusions 1132′ may be formed to have a curve relative to the outer circumferential surface of the base 1131′. For example, each of the plurality of heat dissipation protrusions 1132′ may be formed to have a convex curve relative to the outer circumferential surface of the base 1131′.

[0132] This structure allows smooth heat exchange between the heat dissipation protrusion 1132' and the fluid.

[0133] In addition, the fluid can flow along the curved direction of the heat dissipation protrusions 1132', and the fluid can easily move or convect in the inner space of the main body, improving the uniformity of heating.

[0134] FIG. 8 is a schematic diagram illustrating an electrode-based heating device according to another embodiment of the present invention.

[0135] Referring to FIG. 8, the electrode-based heating device 200 of this embodiment may include a main body portion 220 and a heating unit portion HU.

[0136] For convenience of explanation, the following description will focus on the differences from the above-described embodiment.

[0137] The main body 220 may be configured to accommodate the fluid WT inside.

[0138] The main body 220 may have various shapes and may include at least an inlet 221 for the inflow of the fluid WT and an outlet 222 for the discharge of the fluid WT.

[0139] For example, the inlet portion 221 may be formed toward one side of the main body portion 220, and the outlet portion 222 may be formed toward the other side of the main body portion 220 in a region different from where the inlet portion 221 is formed.

[0140] In an optional embodiment, the region where the inlet portion 221 is formed may be opposite to the region where the outlet portion 222 is formed. For example, the inlet portion 221 may be formed on one side of the region of the main body portion 220 based on the longitudinal direction of the body portion 220, and the outlet portion 222 may be formed on the other opposite region. In this case, the outlet portion 222 may be arranged so as not to overlap with the inlet portion 221.

[0141] FIG. 9 is a schematic diagram of an alternative embodiment of a heating unit according to an embodiment of the present invention.

[0142] For the sake of convenience, the following description will focus on the differences from the above-described embodiment.

[0143] Electrolyzed water IW may be disposed inside the first heating unit HU1, and may be disposed so as to be separated from the fluid WT outside.

[0144] The first heating unit HU1 may include an electrode section 260' having one or more electrodes.

[0145] The electrode portion 260' may include multiple electrodes.

[0146] For example, the electrode unit 260' may include a first electrode 261', a second electrode 262', and a third electrode 263'.

[0147] For example, the first electrode 261', the second electrode 262', and the third electrode 263' may be arranged to be spaced apart from each other.

[0148] In an alternative embodiment, the first electrode 261', the second electrode 262', and the third electrode 263' may include a first terminal 261T', a second terminal 262T', and a third terminal 263T', respectively.

[0149] The heat dissipation section 230' of the first heating unit HU1 can be arranged so as to distinguish between the electrolyzed water IW and the fluid, and for example, the electrolyzed water IW may be arranged inside the heat dissipation section 230'.

[0150] FIG. 10 is a schematic diagram illustrating an electrode-based heating device according to another embodiment of the present invention.

[0151] Referring to FIG. 10, the electrode-based heating device 300 of this embodiment may include a main body portion 320 and a heating unit portion HU.

[0152] The body portion 320 may be configured to have a fluid WT disposed inside it. The fluid WT may include various types, such as a liquid or a gas.

[0153] The body portion 320 can have a variety of shapes, for example, a hollow box shape.

[0154] In alternative embodiments, the main body 320 may have a columnar shape, for example a shape similar to a cylinder, or as another example, a rectangular prism shape, or as another example, a columnar shape having a curved base similar to an ellipse.

[0155] A barrier unit 350 may be disposed inside the body unit 320 .

[0156] The barrier portion 350 may be disposed between the first heating unit HU1 and the second heating unit HU2.

[0157] The space in which the first heating unit HU1 is disposed and the space in which the second heating unit HU2 is disposed may be separated by at least one region via the barrier portion 350.

[0158] Furthermore, the inflowing fluid WT can flow sequentially from the space adjacent to the first heating unit HU1 to the space adjacent to the second heating unit HU2 via the barrier portion 350. This allows the fluid WT in the main body 320 to be efficiently heated via the heating units HU.

[0159] The barrier portion 350 may have a shape extending along the longitudinal direction of the first heating unit HU1 and the second heating unit HU2, and may have a passage separated from the inner surface of the main body portion 320 in at least one region in the longitudinal direction, and such a passage may become a passage for the flow of the fluid WT.

[0160] In an optional embodiment, the barrier portion 350 may restrict the flow of the fluid WT at least from the side of the first heating unit HU1 toward the side of the second heating unit HU2.

[0161] The main body 320 may have various shapes and may include at least an inlet 321 for the inflow of the fluid WT and an outlet 322 for the discharge of the fluid WT.

[0162] In an optional embodiment, the inlet 321 and the outlet 322 may be disposed on either side of the heating unit HU. As a result, the fluid WT flowing in through the inlet 321 is heated while flowing through a space adjacent to the first heating unit HU1 of the heating unit HU, and is heated while passing through the barrier section 350 and flowing through a space adjacent to the second heating unit HU2, thereby improving heating efficiency and heating uniformity over the entire region of the fluid WT.

[0163] The body 320 can be formed from a variety of materials. For example, the body 320 can be formed from a durable, lightweight insulating material. In alternative embodiments, the body 320 can be formed from a plastic material, including various resin families. In other alternative embodiments, the body 320 can include an inorganic material, such as a ceramic.

[0164] Additionally, in other alternative embodiments, the body portion 320 may be formed from a metallic material.

[0165] As another example, the main body 320 may include Teflon resin, which is a fluororesin.

[0166] In an optional embodiment, at least the inner surface of the main body portion 320 adjacent to the fluid WT may include an insulating layer, which may include, for example, an inorganic layer, and may contain inorganic materials including ceramic.

[0167] As another example, an insulating layer containing an organic substance may be formed on the inner surface of the main body 320 that is adjacent to the fluid WT.

[0168] This improves the mutual insulation characteristics with the heating unit part HU, and improves safety when using the electrode-based heating device 300.

[0169] The heating unit section HU may include at least a plurality of heating units HU1 and HU2, and may include, for example, a first heating unit HU1 and a second heating unit HU2.

[0170] In an alternative embodiment, the first heating unit HU1 and the second heating unit HU2 can be arranged to be spaced apart from each other.

[0171] As described above, the barrier section 350 can be disposed between the first heating unit HU1 and the second heating unit HU2.

[0172] Electrolyzed water IW can be disposed inside the first heating unit HU1, and the electrolyzed water IW can be disposed so as to be separated from the fluid WT outside.

[0173] For example, the electrolyzed water IW may be disposed inside the heat dissipation section 330 of the first heating unit HU1, and the electrolyzed water IW and the fluid WT may be disposed so as to be distinguished from each other via the heat dissipation section 330.

[0174] The first heating unit HU1 can include an electrode section 360 having one or more electrodes.

[0175] At least one region of the electrode portion 360 may be disposed inside the first heating unit HU1, for example, inside the heat dissipation portion 330.

[0176] In addition, the electrode unit 360 can be arranged so as to overlap the electrolyzed water IW so as to heat the electrolyzed water IW in the inner region of the heat dissipation unit 330.

[0177] In addition, the electrode unit 360 may overlap the fluid WT disposed inside the body unit 320 in one direction.

[0178] The electrode section 360 may include multiple electrodes.

[0179] For example, the electrode unit 360 may include a first electrode 361 and a second electrode 362.

[0180] In an optional embodiment, the first electrode 361 and the second electrode 362 may include a first terminal portion 361T and a second terminal portion 362T, respectively, and a power source may be connected via the first terminal portion 361T and the second terminal portion 362T.

[0181] The heat dissipation part 330 of the first heating unit HU1 may be disposed to distinguish between the electrolyzed water IW and the fluid WT. For example, the heat dissipation part 330 may be located between the electrolyzed water IW and the fluid WT. The heat dissipation part 330 may also be formed to be spaced apart from the electrode part 360.

[0182] The specific details of the heat dissipation unit 330 may be selectively applied by applying the details described in the above-mentioned embodiments or by modifying them as necessary, so a detailed description thereof will be omitted.

[0183] Also, the structure of FIG. 2 described above may be selectively applied.

[0184] The electrolyzed water IW may be disposed inside the second heating unit HU2 so as to be separated from the fluid WT outside.

[0185] For example, the electrolyzed water IW may be placed inside the heat dissipation section 330 of the second heating unit HU2.

[0186] The second heating unit HU2 may include an electrode section 360 having one or more electrodes. The electrode section 360 may include a plurality of electrodes.

[0187] For example, the electrode unit 360 may include a first electrode 361 and a second electrode 362.

[0188] The contents of the electrolyzed water IW, heat dissipation section 330, and electrode section 360 of the second heating unit HU2 may be the same as the configuration of the first heating unit HU1 described above, and as another example, some of the configuration of the first heating unit HU1 can be selectively modified as needed and applied, so further detailed explanations will be omitted.

[0189] The electrode-based heating device of this embodiment may include a heating unit section including a fluid disposed inside a main body section and a plurality of heating units arranged so as to overlap the fluid in at least one region. For example, although the heating unit section has been described as including two heating units, it may include three or more heating units as needed.

[0190] The plurality of heating units are arranged to be spaced apart from each other, and the fluid overlaps with the outer surfaces of the plurality of heating units, so that the fluid can be easily heated by the heating units. In addition, the fluid can be arranged between the plurality of heating units, so that the efficiency of heating the fluid can be improved.

[0191] In addition, a barrier portion may be formed between the heating units, and the space in which each heating unit is disposed may be separated in at least one region through the barrier portion. For example, the barrier portion may be formed in a shape that extends long in the region where the side surfaces of the heating units face each other. This allows for smoother fluid flow through the separated passages between the end of the barrier portion and the inner surface of the main body, rather than fluid flow from at least the side surface of one heating unit toward the side surface of an adjacent heating unit.

[0192] This allows the fluid that flows in through the inlet portion to be heated while flowing in a first direction in the area adjacent to the first heating unit, and then to pass through the passage portion between the barrier portion and the main body portion and be heated while flowing in a second direction that intersects the first direction in the area adjacent to the second heating unit.

[0193] As a result, the fluid can be heated smoothly while flowing through the spaces corresponding to each heating unit in the inner space of the main body, thereby reducing or preventing uneven heating of different regions of the fluid inside the main body.

[0194] Although not shown, the modified examples of the heating unit in FIGS. 4 to 7 and the details of the heating unit described in the above-described embodiment can be selectively applied to this embodiment.

[0195] FIG. 11 is a schematic diagram illustrating an electrode-based heating device according to another embodiment of the present invention; FIG. 12 is a schematic diagram illustrating an alternative embodiment of the heating unit of FIG. 11; and FIG. 13 is an exemplary diagram illustrating fluid flow in the electrode-based heating device of FIG. 11.

[0196] The electrode-based heating device 400 of this embodiment may include a main body portion 420 and a heating unit portion HU.

[0197] The heating unit section HU can include a plurality of heating units HU1, HU2, HU3, and HU4.

[0198] The body portion 420 may be configured to have a fluid WT disposed inside it. The fluid WT may include various types, such as a liquid or a gas.

[0199] The body portion 420 can have a variety of shapes, for example, a hollow box shape.

[0200] In an optional embodiment, the main body portion 420 may have a bottom portion 441 inside which the flow of the fluid WT is restricted, and may include an upper portion opposite the bottom portion 441.

[0201] In an optional embodiment, the main body portion 420 may include a restriction area BTA in which the flow of the fluid WT is restricted, and the restriction area BTA may be defined as a bottom portion 441, a side portion 442, and a lower portion 423.

[0202] A barrier unit 450 may be disposed inside the body unit 420 .

[0203] The barrier portion 450 can be positioned to distinguish between the multiple heating units HU1, HU2, HU3, and HU4.

[0204] For example, the barrier unit 450 may include a first barrier 451, a second barrier 452, and a third barrier 453, which may be arranged spaced apart from one another in sequence.

[0205] The first barrier 451 may be disposed between the first heating unit HU1 and the second heating unit HU2. The first barrier 451 may separate the space in which the first heating unit HU1 is disposed from the space in which the second heating unit HU2 is disposed in at least one region.

[0206] Furthermore, the inflowing fluid WT can flow sequentially from the space adjacent to the first heating unit HU1 to the space adjacent to the second heating unit HU2 via the first barrier 451. This allows the fluid WT in the main body 420 to be efficiently heated via the first heating unit HU1 and the second heating unit HU2.

[0207] The first barrier 451 may have a shape extending along the longitudinal direction of the first heating unit HU1 and the second heating unit HU2, and may have a first passage TH1 separated from the inner surface of the main body 420 in at least one region in the longitudinal direction, and such first passage TH1 may become a passage for the flow of the fluid WT.

[0208] In an optional embodiment, the first barrier 451 may restrict the flow of the fluid WT at least from the side of the first heating unit HU1 toward the side of the second heating unit HU2.

[0209] The second barrier 452 may be disposed between the second heating unit HU2 and the third heating unit HU3. The space in which the second heating unit HU2 is disposed and the space in which the third heating unit HU3 is disposed may be separated by the second barrier 452 in at least one region.

[0210] Furthermore, the inflowing fluid WT can flow sequentially from the space adjacent to the second heating unit HU2 to the space adjacent to the third heating unit HU3 via the second barrier 452. This allows the fluid WT in the main body 420 to be efficiently heated via the second heating unit HU2 and the third heating unit HU3.

[0211] The second barrier 452 may have a shape extending along the longitudinal direction of the second heating unit HU2 and the third heating unit HU3, and may have a second passage TH2 separated from the inner surface of the main body 420 in at least one region in the longitudinal direction, and such second passage TH2 may become a passage for the flow of the fluid WT.

[0212] The second passage TH2 may not overlap with the first passage TH1; for example, the second passage TH2 may be adjacent to the end of the second heating unit HU2 in the first direction, and the first passage TH1 may be adjacent to the end of the second heating unit HU2 in the opposite direction to the first direction.

[0213] As a specific example, the second passage TH2 and the first passage TH1 may be formed to extend in opposite directions.

[0214] In an optional embodiment, the second barrier 452 may restrict the flow of the fluid WT at least from the side of the second heating unit HU2 toward the side of the third heating unit HU3.

[0215] The third barrier 453 may be disposed between the third heating unit HU3 and the fourth heating unit HU4. The space in which the third heating unit HU3 is disposed and the space in which the fourth heating unit HU4 is disposed may be separated by the third barrier 453 in at least one region.

[0216] Furthermore, the inflowing fluid WT can flow sequentially from the space adjacent to the third heating unit HU3 to the space adjacent to the fourth heating unit HU4 via the third barrier 453. This allows the fluid WT in the main body 420 to be efficiently heated via the third heating unit HU3 and the fourth heating unit HU4.

[0217] The third barrier 453 may have a shape extending along the longitudinal direction of the third heating unit HU3 and the fourth heating unit HU4, and may have a third passage TH3 separated from the inner surface of the main body 420 in at least one region in the longitudinal direction, and such third passage TH3 may become a passage for the flow of the fluid WT.

[0218] The third passage TH3 may not overlap with the second passage TH2, and for example, the third passage TH3 and the second passage TH2 may be formed to extend in opposite directions.

[0219] In an optional embodiment, the third passage TH3 can overlap the first passage TH1.

[0220] In an optional embodiment, the third barrier 453 may restrict the flow of the fluid WT at least from the side of the third heating unit HU3 toward the side of the fourth heating unit HU4.

[0221] The passage portions, for example, the first passage TH1, the second passage TH2, and the third passage TH3, may have a width W for the fluid WT to pass through, and in an alternative embodiment, these widths W may all be the same.

[0222] The main body 420 may have various shapes and may include at least an inlet 421 for the inflow of the fluid WT and an outlet 422 for the discharge of the fluid WT.

[0223] The inlet 421 and the outlet 422 may be disposed on both sides of the restriction area BTA, such that the fluid WT flowing into the inlet 421 passes through one side of the restriction area BTA, and then passes through an area adjacent to the heating unit HU, where it is heated, and then is discharged to the outlet 422.

[0224] In an optional embodiment, the inlet 421 and the outlet 422 may be disposed on either side of the heating unit HU, thereby improving the heating efficiency and the heating uniformity over the entire area of ​​the fluid WT.

[0225] Body portion 420 can be formed from a variety of materials. For example, body portion 420 can be formed from a durable, lightweight, insulating material. In alternative embodiments, body portion 420 can be formed from a plastic material, including various families of resins. In other alternative embodiments, body portion 420 can include an inorganic material, such as a ceramic.

[0226] Additionally, in other alternative embodiments, the body portion 420 may be formed from a metallic material.

[0227] As another example, the main body 420 may include Teflon resin, which is a fluororesin.

[0228] In an optional embodiment, at least the inner surface of the main body portion 420 adjacent to the fluid WT may include an insulating layer, which may include, for example, an inorganic layer, and may contain inorganic materials including ceramic.

[0229] As another example, an insulating layer containing an organic substance may be formed on the inner surface of the main body 420 that is adjacent to the fluid WT.

[0230] This improves the mutual insulation characteristics with the heating unit part HU, and improves safety when using the electrode-based heating device 400.

[0231] The heating unit section HU may include at least a plurality of heating units HU1, HU2, HU3, and HU4, and may include, for example, a first heating unit HU1, a second heating unit HU2, a third heating unit HU3, and a fourth heating unit HU4.

[0232] In an alternative embodiment, the first heating unit HU1, the second heating unit HU2, the third heating unit HU3, and the fourth heating unit HU4 may be arranged to be spaced apart from one another.

[0233] The first heating unit HU1 will be described with reference to FIG.

[0234] Electrolyzed water IW may be disposed inside the first heating unit HU1, and may be disposed so as to be separated from the fluid WT outside.

[0235] For example, the electrolyzed water IW may be disposed inside the heat dissipation section 430 of the first heating unit HU1, and the electrolyzed water IW and the fluid WT may be disposed so as to be distinguished from each other via the heat dissipation section 430.

[0236] The first heating unit HU1 can include an electrode section 460 having one or more electrodes.

[0237] At least one region of the electrode portion 460 may be disposed inside the first heating unit HU1, for example, inside the heat dissipation portion 430.

[0238] In addition, the electrode unit 460 can be arranged so as to overlap the electrolyzed water IW so as to heat the electrolyzed water IW in the inner region of the heat dissipation unit 430.

[0239] In addition, the electrode unit 460 may overlap the fluid WT disposed inside the body unit 420 in one direction.

[0240] The electrode section 460 may include multiple electrodes.

[0241] For example, the electrode unit 460 may include a first electrode 461 and a second electrode 462.

[0242] In an optional embodiment, the first electrode 461 and the second electrode 462 may include a first terminal portion 461T and a second terminal portion 462T, respectively, and a power source may be connected via the first terminal portion 461T and the second terminal portion 462T.

[0243] In an optional embodiment, the second heating unit HU2 may have a protective portion 460C formed on the first terminal portion 461T and the second terminal portion 462T as shown.

[0244] The heat dissipation unit 430 of the first heating unit HU1 may be disposed to distinguish between the electrolyzed water IW and the fluid WT. For example, the heat dissipation unit 430 may be located between the electrolyzed water IW and the fluid WT. The heat dissipation unit 430 may also be formed to be spaced apart from the electrode unit 460.

[0245] The specific details of the heat dissipation unit 430 can be selectively applied by applying the details described in the above-mentioned embodiments, or can be modified as necessary, so a detailed description will be omitted.

[0246] Also, the structure of FIG. 2 described above may be selectively applied.

[0247] The second heating unit HU2 to the fourth heating unit HU4 may have the same configuration as the first heating unit HU1, and may be modified within a similar range as necessary, so a detailed description thereof will be omitted.

[0248] The flow of the fluid WT will be described with reference to Figure 13. For ease of explanation, the multiple heating units HU1, HU2, HU3, and HU4 of the heating unit section HU are omitted from Figure 19. For ease of explanation, the flow of the fluid WT is indicated by arrows. Such arrows are for ease of explanation and may be used to roughly illustrate the direction of flow.

[0249] As shown in FIG. 13 , the unheated fluid WT, e.g., tap water, flowing in through the inlet 421 can pass through the first heating path LA1. The first heating path LA1 can include an overlapping area with the first heating unit HU1. The fluid WT can flow from the first heating path LA1 through the first passage TH1 to the second heating path LA2. The second heating path LA2 can include an overlapping area with the second heating unit HU2. The fluid WT can flow from the second heating path LA2 through the second passage TH2 to the third heating path LA3. The third heating path LA3 can include an overlapping area with the third heating unit HU3. The fluid WT can flow from the third heating path LA3 through the third passage TH3 to the fourth heating path LA4. The fourth heating path LA4 can include an overlapping area with the fourth heating unit HU4. The fluid WT can then be discharged through the outlet 422, e.g., heated hot water can be discharged.

[0250] The electrode-based heating device of this embodiment can include a heating unit portion having a fluid disposed inside a main body portion and including a plurality of heating units arranged so that at least one region overlaps with the fluid.

[0251] The plurality of heating units are arranged to be spaced apart from each other, and the fluid overlaps with the outer surfaces of the plurality of heating units, so that the fluid can be easily heated by the heating units. The fluid can also be arranged between the plurality of heating units, so that the efficiency of heating the fluid can be improved.

[0252] Furthermore, a barrier section can be formed between the plurality of heating units, and a passage section can be formed in one region of the barrier section so that a fluid can pass through.

[0253] For example, the barrier portion may include a plurality of barriers, and the passage portions of each barrier may be formed alternately with each other.

[0254] This structure allows fluid to easily move between the heating units and the adjacent spaces, which are separated from each other by the barrier portions.

[0255] Furthermore, depending on the specific configuration of the passage portion, the fluid may be effectively heated by the first heating unit while flowing in one direction, pass through the first passage portion, be effectively heated by the second heating unit while flowing in the opposite direction, pass through the second passage, be effectively heated by the third heating unit while flowing in the same direction, pass through the third passage portion, be heated by the fourth heating unit while flowing in the opposite direction, and be discharged through the discharge portion.

[0256] As a result, the fluid can be smoothly heated while flowing through the spaces corresponding to each heating unit in the inner space of the main body, reducing or preventing uneven heating of different regions of the fluid inside the main body, and easily improving the thermal efficiency of the electrode-based heating device.

[0257] Although not shown, the modified examples of the heating unit in FIGS. 4 to 7 and the details of the heating unit described in the above-described embodiment can be selectively applied to this embodiment.

[0259] FIG. 19 is an exemplary diagram illustrating fluid flow in the electrode-based heating device of FIG.

[0260] FIG. 20 is a cross-sectional view taken along line XVII-XVII in FIG.

[0261] The electrode-based heating device 500 of this embodiment may include a main body portion 520 and a heating unit portion HU.

[0262] The heating unit section HU may include a plurality of heating units HU1, HU2, HU3, HU4, HU5, and HU6.

[0263] The body portion 520 may be configured to have a fluid WT disposed inside it. The fluid WT may include various types, such as a liquid or a gas.

[0264] The body portion 520 can have a variety of shapes, for example, a hollow box shape.

[0265] In an optional embodiment, the main body portion 520 may have a bottom portion 541 inside which the flow of the fluid WT is restricted, and may include an upper portion opposite the bottom portion 541.

[0266] In an optional embodiment, the main body portion 520 may include a restriction area BTA where the flow of the fluid WT is restricted, and the restriction area BTA may be defined as a bottom portion 541, a side portion 542, and a lower portion 523.

[0267] A barrier unit 550 may be disposed inside the body unit 520 .

[0268] The barrier portion 550 may be positioned to distinguish between the multiple heating units HU1, HU2, HU3, HU4, HU5, and HU6.

[0269] For example, the barrier unit 550 may include a first barrier 551, a second barrier 552, a third barrier 553, a fourth barrier 554, and a fifth barrier 555, which may be arranged spaced apart from one another in sequence.

[0270] The first barrier 551 may be disposed between the first heating unit HU1 and the second heating unit HU2. The first barrier 551 may separate the space in which the first heating unit HU1 is disposed from the space in which the second heating unit HU2 is disposed in at least one region.

[0271] Furthermore, the inflowing fluid WT can flow sequentially from the space adjacent to the first heating unit HU1 to the space adjacent to the second heating unit HU2 via the first barrier 551. This allows the fluid WT in the main body 520 to be efficiently heated via the first heating unit HU1 and the second heating unit HU2.

[0272] The first barrier 551 may have a shape extending along the longitudinal direction of the first heating unit HU1 and the second heating unit HU2, and may have a first passage TH1 separated from the inner surface of the main body 520 in at least one region in the longitudinal direction, and such first passage TH1 may become a passage for the flow of the fluid WT.

[0273] In an optional embodiment, the flow of the fluid WT from at least a side surface of the first heating unit HU1 toward a side surface of the second heating unit HU2 may be restricted by the first barrier 551. For example, as shown in Fig. 20, the first barrier 551 may be connected to both opposing side surfaces of the inner surface of the main body 520 in the thickness direction of the first heating unit HU1.

[0274] The second barrier 552 may be disposed between the second heating unit HU2 and the third heating unit HU3. The space in which the second heating unit HU2 is disposed and the space in which the third heating unit HU3 is disposed may be separated by the second barrier 552 in at least one region.

[0275] Furthermore, the inflowing fluid WT can flow sequentially from the space adjacent to the second heating unit HU2 to the space adjacent to the third heating unit HU3 via the second barrier 552. This allows the fluid WT in the main body 520 to be efficiently heated via the second heating unit HU2 and the third heating unit HU3.

[0276] The second barrier 552 may have a shape extending along the longitudinal direction of the second heating unit HU2 and the third heating unit HU3, and may have a second passage TH2 separated from the inner surface of the main body portion 520 in at least one region in the longitudinal direction, and such second passage TH2 may serve as a passage for the flow of the fluid WT.

[0277] The second passage TH2 may not overlap with the first passage TH1; for example, the second passage TH2 may be adjacent to the end of the second heating unit HU2 in the first direction, and the first passage TH1 may be adjacent to the end of the second heating unit HU2 in the opposite direction to the first direction.

[0278] As a specific example, the second passage TH2 may not overlap with the first passage TH1, and for example, the second passage TH2 and the first passage TH1 may be formed to extend toward opposite ends of both side ends of the heating unit HU.

[0279] In an optional embodiment, the flow of the fluid WT from at least a side surface of the second heating unit HU2 toward a side surface of the third heating unit HU3 may be restricted by the second barrier 552. For example, as shown in Fig. 20, the second barrier 552 may be connected to both opposing side surfaces of the inner surface of the main body 520 in the thickness direction of the second heating unit HU2.

[0280] The third barrier 553 may be disposed between the third heating unit HU3 and the fourth heating unit HU4. The space in which the third heating unit HU3 is disposed and the space in which the fourth heating unit HU4 is disposed may be separated by the third barrier 553 in at least one region.

[0281] Furthermore, the inflowing fluid WT can flow sequentially from the space adjacent to the third heating unit HU3 to the space adjacent to the fourth heating unit HU4 via the third barrier 553. This allows the fluid WT in the main body 520 to be efficiently heated via the third heating unit HU3 and the fourth heating unit HU4.

[0282] The third barrier 553 may have a shape extending along the longitudinal direction of the third heating unit HU3 and the fourth heating unit HU4, and may have a third passage TH3 separated from the inner surface of the main body 520 in at least one region in the longitudinal direction, and such third passage TH3 may become a passage for the flow of the fluid WT.

[0283] The third passage TH3 may not overlap with the second passage TH2, and for example, the third passage TH3 and the second passage TH2 may be formed to extend toward opposite ends of both ends of the heating unit HU.

[0284] In an optional embodiment, the third passage TH3 can overlap the first passage TH1.

[0285] In an optional embodiment, the flow of the fluid WT from at least a side surface of the third heating unit HU3 toward a side surface of the fourth heating unit HU4 may be restricted by the third barrier 553. For example, as shown in Fig. 20, the third barrier 553 may be connected to both opposing side surfaces of the inner surface of the main body 520 in the thickness direction of the third heating unit HU3.

[0286] The fourth barrier 554 may be disposed between the fourth heating unit HU4 and the fifth heating unit HU5. The fourth barrier 554 may separate the space in which the fourth heating unit HU4 is disposed from the space in which the fifth heating unit HU5 is disposed in at least one region.

[0287] Furthermore, the fluid WT that has flowed in can flow sequentially from the space adjacent to the fourth heating unit HU4 to the space adjacent to the fifth heating unit HU5 via the fourth barrier 554. This allows the fluid WT in the main body 520 to be efficiently heated via the fourth heating unit HU4 and the fifth heating unit HU5.

[0288] The fourth barrier 554 may have a shape extending along the longitudinal direction of the fourth heating unit HU4 and the fifth heating unit HU5, and may have a fourth passage TH4 separated from the inner surface of the main body portion 520 in at least one region in the longitudinal direction, and such fourth passage TH4 may become a passage for the flow of the fluid WT.

[0289] The fourth passage TH4 may not overlap with the third passage TH3, and for example, the fourth passage TH4 and the third passage TH3 may be formed to extend toward opposite ends of both side ends of the heating unit HU.

[0290] In an optional embodiment, the fourth passage TH4 can overlap the second passage TH2.

[0291] In an optional embodiment, the flow of the fluid WT from at least a side surface of the fourth heating unit HU4 toward a side surface of the fifth heating unit HU5 may be restricted by the fourth barrier 554. For example, as shown in Fig. 20, the fourth barrier 554 may be connected to both side surfaces of the inner surface of the main body 520 that face each other in the thickness direction of the fourth heating unit HU4.

[0292] The fifth barrier 555 can be disposed between the fifth heating unit HU5 and the sixth heating unit HU6. The fifth barrier 555 can separate the space in which the fifth heating unit HU5 is disposed from the space in which the sixth heating unit HU6 is disposed in at least one region.

[0293] Furthermore, the fluid WT that has flowed in can flow sequentially from the space adjacent to the fifth heating unit HU5 to the space adjacent to the sixth heating unit HU6 via the fifth barrier 555. This allows the fluid WT in the main body 520 to be efficiently heated via the fifth heating unit HU5 and the sixth heating unit HU6.

[0294] The fifth barrier 555 may have a shape extending along the longitudinal direction of the fifth heating unit HU5 and the sixth heating unit HU6, and may have a fifth passage TH5 separated from the inner surface of the main body 520 in at least one region in the longitudinal direction, and such fifth passage TH5 may become a passage for the flow of the fluid WT.

[0295] The fifth passage TH5 may not overlap with the fourth passage TH4. For example, the fifth passage TH5 and the fourth passage TH4 may be formed to extend toward opposite ends of both ends of the heating unit HU.

[0296] In an alternative embodiment, the fifth passage TH5 can overlap with the third passage TH3 or the first passage TH1.

[0297] In an optional embodiment, the flow of the fluid WT from at least a side surface of the fifth heating unit HU5 toward a side surface of the sixth heating unit HU6 may be restricted by the fifth barrier 555. For example, as shown in Fig. 20, the fifth barrier 555 may be connected to both opposing side surfaces of the inner surface of the main body 520 in the thickness direction of the fifth heating unit HU5.

[0298] The passage portions, for example, the first passage TH1, the second passage TH2, and the third passage TH3, may have widths to allow the fluid WT to pass through, and in an alternative embodiment, these widths may all be the same.

[0299] The main body 520 may have various shapes and may include at least an inlet 521 for the inflow of the fluid WT and an outlet 522 for the discharge of the fluid WT.

[0300] The inlet 521 and the outlet 522 may be disposed on both sides of the restriction area BTA, such that the fluid WT flowing into the inlet 521 passes through one side of the restriction area BTA, and then passes through an area adjacent to the heating unit HU, where it is heated, and then is discharged to the outlet 522.

[0301] In an optional embodiment, the inlet 521 and the outlet 522 may be disposed on either side of the heating unit HU, thereby improving the heating efficiency and the heating uniformity over the entire area of ​​the fluid WT.

[0302] The body 520 can be formed from a variety of materials. For example, the body 520 can be formed from a durable, lightweight insulating material. In alternative embodiments, the body 520 can be formed from a plastic material, including various resin families. In other alternative embodiments, the body 520 can include an inorganic material, such as a ceramic.

[0303] Additionally, in other alternative embodiments, the body portion 520 may be formed from a metallic material.

[0304] As another example, the main body 520 may include Teflon resin, which is a fluororesin.

[0305] In an optional embodiment, at least the inner surface of the main body portion 520 adjacent to the fluid WT may include an insulating layer, which may include, for example, an inorganic layer, and may contain inorganic materials including ceramic.

[0306] As another example, an insulating layer containing an organic substance may be formed on the inner surface of the main body 520 that is adjacent to the fluid WT.

[0307] This improves the mutual insulation characteristics with the heating unit part HU, and improves safety when using the electrode-based heating device 500.

[0308] The heating unit section HU may include at least a plurality of heating units HU1, HU2, HU3, HU4, HU5, and HU6, and may include, for example, a first heating unit HU1, a second heating unit HU2, a third heating unit HU3, a fourth heating unit HU4, a fifth heating unit HU5, and a sixth heating unit HU6.

[0309] In an optional embodiment, the first heating unit HU1, the second heating unit HU2, the third heating unit HU3, the fourth heating unit HU4, the fifth heating unit HU5, and the sixth heating unit HU6 may be spaced apart from one another.

[0310] The first heating unit HU1 will be described with reference to FIG.

[0311] Electrolyzed water IW can be disposed inside the first heating unit HU1, and the electrolyzed water IW can be disposed so as to be separated from the fluid WT outside.

[0312] For example, the electrolyzed water IW may be disposed inside the heat dissipation section 530 of the first heating unit HU1, and the electrolyzed water IW and the fluid WT may be disposed so as to be distinguished from each other via the heat dissipation section 530.

[0313] The first heating unit HU1 can include an electrode section 560 having one or more electrodes.

[0314] At least one region of the electrode portion 560 may be disposed inside the first heating unit HU1, and may be disposed inside the heat dissipation portion 530, for example.

[0315] In addition, the electrode unit 560 can be arranged so as to overlap the electrolyzed water IW so as to heat the electrolyzed water IW in the inner region of the heat dissipation unit 530.

[0316] In addition, the electrode unit 560 may overlap the fluid WT disposed inside the body unit 520 in one direction.

[0317] The electrode section 560 can include multiple electrodes.

[0318] For example, the electrode unit 560 may include a first electrode 561 and a second electrode 562.

[0319] In an optional embodiment, the first electrode 561 and the second electrode 562 may include a first terminal portion 561T and a second terminal portion 562T, respectively, and a power source may be connected via the first terminal portion 561T and the second terminal portion 562T.

[0320] In an optional embodiment, the second heating unit HU2 may have a protective portion 560C formed on the first terminal portion 561T and the second terminal portion 562T as shown.

[0321] The heat dissipation unit 530 of the first heating unit HU1 may be disposed to distinguish between the electrolyzed water IW and the fluid WT. For example, the heat dissipation unit 530 may be located between the electrolyzed water IW and the fluid WT. The heat dissipation unit 530 may also be formed to be spaced apart from the electrode unit 560.

[0322] In an optional embodiment, as shown in FIG. 16, the heat dissipation part 530' of the first heating unit HU1 may include a base 531' and a heat dissipation protrusion 532'.

[0323] The base 531' may be formed in a shape that surrounds the electrolyzed water IW, and may have a shape similar to a cylinder, for example.

[0324] The heat dissipation protrusions 532' may be provided in plurality and may be connected to the base 531' and protrude from the base 531' toward the fluid. The base 531' may be formed to face the electrode unit 560'.

[0325] The specific contents are the same as those explained in the embodiment of FIG. 5 above, or can be modified as necessary, so explanations will be omitted.

[0326] Also, the structure of FIG. 2 described above may be selectively applied.

[0327] FIG. 17 is a perspective view that schematically illustrates an alternative embodiment of the heating unit of FIG.

[0328] 17, the first heating unit HU1 may have an overall outer shape similar to an elongated pillar. For example, the base of the first heating unit HU1 may have an elongated structure, and a plurality of heat dissipation protrusions 532″ may be formed on the outer surface of the base and extend along the longitudinal direction of the base.

[0329] FIG. 18 is a perspective view that schematically illustrates an alternative embodiment of the heating unit of FIG.

[0330] 18, the first heating unit HU1 may have an overall outer shape similar to an elongated pillar. For example, the base of the first heating unit HU1 may have an elongated structure, and heat dissipation protrusions 1532" may be formed on the outer surface of the base along the outer periphery of the base. For example, a plurality of heat dissipation protrusions 1532" may surround the outer surface of the base.

[0331] Alternatively, one or more heat dissipation protrusions 1532" may be spirally formed in the longitudinal direction around the outer surface of the base, and for example, may have a single, elongated spiral structure.

[0332] This increases the contact area between the heat dissipation protrusions 1532'' and the fluid, improving the heat dissipation effect. In addition, the fluid flows easily along the spiral shape of the heat dissipation protrusions 1532'', facilitating the movement of the fluid.

[0333] The second heating unit HU2 to the sixth heating unit HU6 may have the same configuration as the first heating unit HU1, and may be modified within a similar range as necessary, so a detailed description will be omitted.

[0334] The flow of the fluid WT will be described with reference to Figure 19. For ease of explanation, the multiple heating units HU1, HU2, HU3, HU4, HU5, and HU6 of the heating unit section HU are omitted from Figure 13. For ease of explanation, the flow of the fluid WT is indicated by arrows. Such arrows are for ease of explanation and may be used to roughly illustrate the direction of flow.

[0335] As shown in FIG. 19, the unheated fluid WT, e.g., tap water, flowing in through the inlet 521 can pass through the first heating path LA1. The first heating path LA1 can include an overlapping area with the first heating unit HU1. The fluid WT can flow from the first heating path LA1 through the first passage TH1 to the second heating path LA2. The second heating path LA2 can include an overlapping area with the second heating unit HU2. The fluid WT can flow from the second heating path LA2 through the second passage TH2 to the third heating path LA3. The third heating path LA3 can include an overlapping area with the third heating unit HU3. The fluid WT can flow from the third heating path LA3 through the third passage TH3 to the fourth heating path LA4. The fourth heating path LA4 can include an overlapping area with the fourth heating unit HU4. The fluid WT can flow from the fourth heating path LA4 through the fourth passage TH4 to the fifth heating path LA5. The fifth heating path LA5 may include an overlapping region with the fifth heating unit HU5. The fluid WT may flow from the fifth heating path LA5 through the fifth passage TH5 to the sixth heating path LA6. The sixth heating path LA6 may include an overlapping region with the sixth heating unit HU6.

[0336] The fluid WT may then be discharged via the outlet 522, for example heated hot water.

[0337] The electrode-based heating device of this embodiment can include a heating unit portion having a fluid disposed inside a main body portion and including a plurality of heating units arranged so that at least one region overlaps with the fluid.

[0338] The plurality of heating units are arranged to be spaced apart from each other, and the fluid overlaps with the outer surfaces of the plurality of heating units, so that the fluid can be easily heated by the heating units. The fluid can also be arranged between the plurality of heating units, so that the efficiency of heating the fluid can be improved.

[0339] Furthermore, a barrier section can be formed between the plurality of heating units, and a passage section can be formed in one region of the barrier section so that a fluid can pass through.

[0340] For example, the barrier portion may include a plurality of barriers, and the passage portions of each barrier may be formed alternately with each other.

[0341] This structure allows fluid to easily move between the heating units and the adjacent spaces, which are separated from each other by the barrier portions.

[0342] In addition, depending on the specific configuration of the passage, the fluid may flow in one direction and be heated sequentially by the heating units of the heating unit section. For example, the fluid may be heated while flowing along the sequentially arranged heating units, and the direction of the fluid flow may be reversed each time the fluid moves to an adjacent heating unit.

[0343] This allows a smooth flow of fluid to be generated along each heating unit, improving the efficiency of heating the fluid.

[0344] Although not shown, the modified examples of the heating unit in FIGS. 4 to 7 and the details of the heating unit described in the above-described embodiment can be selectively applied to this embodiment.

[0345] FIG. 21 is a schematic diagram illustrating an electrode-based heating device according to another embodiment of the present invention.

[0346] 22 is a cross-sectional view taken along line XI-XXI in FIG. 21, FIG. 23 is a cross-sectional view taken along line XXII-XXII in FIG. 21, FIG. 24 is a cross-sectional view taken along line XXIII-XXIII in FIG. 21, and FIG. 25 is a cross-sectional view taken along line XXIV-XXIV in FIG. 21.

[0347] The electrode-based heating device 600 of this embodiment may include a main body portion 620 and a heating unit portion HU.

[0348] The heating unit section HU may include a plurality of heating units HU1, HU2, HU3, HU4, HU5, and HU6.

[0349] The body 620 may be configured to have a fluid WT disposed inside it. The fluid WT may include various types, such as a liquid or a gas.

[0350] The body portion 620 can have a variety of shapes, for example, a hollow box shape.

[0351] In an optional embodiment, the main body portion 620 may have a bottom portion 641 inside which the flow of the fluid WT is restricted, and may include an upper portion opposite the bottom portion 641.

[0352] In an optional embodiment, the main body portion 620 may include a restriction area BTA through which the flow of the fluid WT is restricted, and the restriction area BTA may be defined as a bottom portion 641, a side portion 642, and a lower portion 623.

[0353] A barrier unit 650 may be disposed inside the main body unit 620 .

[0354] The barrier portion 650 may be positioned to distinguish between the multiple heating units HU1, HU2, HU3, HU4, HU5, and HU6.

[0355] For example, the barrier section 650 may include a first barrier 651, a second barrier 652, a third barrier 653, a fourth barrier 654, and a fifth barrier 655, which may be arranged spaced apart from one another in sequence.

[0356] The first barrier 651 can be disposed between the first heating unit HU1 and the second heating unit HU2. The first barrier 651 can separate the space in which the first heating unit HU1 is disposed from the space in which the second heating unit HU2 is disposed in at least one region.

[0357] Furthermore, the inflowing fluid WT can flow sequentially from the space adjacent to the first heating unit HU1 to the space adjacent to the second heating unit HU2 via the first barrier 651. This allows the fluid WT in the main body 620 to be efficiently heated via the first heating unit HU1 and the second heating unit HU2.

[0358] The first barrier 651 may have a shape extending along the longitudinal direction of the first heating unit HU1 and the second heating unit HU2, and may have a first passage TH1 separated from the inner surface of the main body 620 in at least one region in the longitudinal direction, and such first passage TH1 may become a passage for the flow of the fluid WT.

[0359] In an optional embodiment, the first barrier 651 may restrict the flow of the fluid WT from at least a side surface of the first heating unit HU1 toward a side surface of the second heating unit HU2. For example, as shown in Fig. 22, the first barrier 651 may be connected to both opposing side surfaces of the inner surface of the main body 620 in the thickness direction of the first heating unit HU1. Of the surfaces of the first barrier 651, the surfaces facing the first heating unit HU1 and the second heating unit HU2 may have curved surfaces, and for example, may have curved surfaces corresponding to the first heating unit HU1 and the second heating unit HU2.

[0360] The second barrier 652 may be disposed between the second heating unit HU2 and the third heating unit HU3. The space in which the second heating unit HU2 is disposed and the space in which the third heating unit HU3 is disposed may be separated by the second barrier 652 in at least one region.

[0361] Furthermore, the inflowing fluid WT can flow sequentially from the space adjacent to the second heating unit HU2 to the space adjacent to the third heating unit HU3 via the second barrier 652. This allows the fluid WT in the main body 620 to be efficiently heated via the second heating unit HU2 and the third heating unit HU3.

[0362] The second barrier 652 may have a shape extending along the longitudinal direction of the second heating unit HU2 and the third heating unit HU3, and may have a second passage TH2 separated from the inner surface of the main body 620 in at least one region in the longitudinal direction, and such second passage TH2 may become a passage for the flow of the fluid WT.

[0363] The second passage TH2 may not overlap with the first passage TH1; for example, the second passage TH2 may be adjacent to the end of the second heating unit HU2 in the first direction, and the first passage TH1 may be adjacent to the end of the second heating unit HU2 in the opposite direction to the first direction.

[0364] As a specific example, the second passage TH2 may not overlap with the first passage TH1, and for example, the second passage TH2 and the first passage TH1 may be formed to extend toward opposite ends of both side ends of the heating unit HU.

[0365] In an optional embodiment, the second barrier 652 may restrict the flow of the fluid WT from at least a side surface of the second heating unit HU2 toward a side surface of the third heating unit HU3. For example, as shown in Fig. 22, the second barrier 652 may be connected to both opposing side surfaces of the inner surface of the main body 620 in the thickness direction of the second heating unit HU2. Of the surfaces of the second barrier 652, the surfaces facing the second heating unit HU2 and the third heating unit HU3 may have a curved shape, and for example, may have curved surfaces corresponding to the second heating unit HU2 and the third heating unit HU3.

[0366] The third barrier 653 may be disposed between the third heating unit HU3 and the fourth heating unit HU4. The space in which the third heating unit HU3 is disposed and the space in which the fourth heating unit HU4 is disposed may be separated by the third barrier 653 in at least one region.

[0367] Furthermore, the inflowing fluid WT can flow sequentially from the space adjacent to the third heating unit HU3 to the space adjacent to the fourth heating unit HU4 via the third barrier 653. This allows the fluid WT in the main body 620 to be efficiently heated via the third heating unit HU3 and the fourth heating unit HU4.

[0368] The third barrier 653 may have a shape extending along the longitudinal direction of the third heating unit HU3 and the fourth heating unit HU4, and may have a third passage TH3 separated from the inner surface of the main body 620 in at least one region in the longitudinal direction, and such third passage TH3 may become a passage for the flow of the fluid WT.

[0369] The third passage TH3 may not overlap with the second passage TH2, and for example, the third passage TH3 and the second passage TH2 may be formed to extend toward opposite ends of both ends of the heating unit HU.

[0370] In an optional embodiment, the third passage TH3 can overlap the first passage TH1.

[0371] In an optional embodiment, the third barrier 653 may restrict the flow of the fluid WT from at least a side surface of the third heating unit HU3 toward a side surface of the fourth heating unit HU4. For example, as shown in Fig. 22, the third barrier 653 may be connected to both opposing side surfaces of the inner surface of the main body 620 in the thickness direction of the third heating unit HU3. Of the surfaces of the third barrier 653, the surfaces facing the third heating unit HU3 and the fourth heating unit HU4 may have a curved shape, and for example, may have curved surfaces corresponding to the third heating unit HU3 and the fourth heating unit HU4.

[0372] The fourth barrier 654 may be disposed between the fourth heating unit HU4 and the fifth heating unit HU5. The fourth barrier 654 may separate the space in which the fourth heating unit HU4 is disposed from the space in which the fifth heating unit HU5 is disposed in at least one region.

[0373] Furthermore, the fluid WT that has flowed in can flow sequentially from the space adjacent to the fourth heating unit HU4 to the space adjacent to the fifth heating unit HU5 via the fourth barrier 654. This allows the fluid WT in the main body 620 to be efficiently heated via the fourth heating unit HU4 and the fifth heating unit HU5.

[0374] The fourth barrier 654 may have a shape extending along the longitudinal direction of the fourth heating unit HU4 and the fifth heating unit HU5, and may have a fourth passage TH4 separated from the inner surface of the main body portion 620 in at least one region in the longitudinal direction, and such fourth passage TH4 may become a passage for the flow of the fluid WT.

[0375] The fourth passage TH4 may not overlap with the third passage TH3, and for example, the fourth passage TH4 and the third passage TH3 may be formed to extend toward opposite ends of both side ends of the heating unit HU.

[0376] In an optional embodiment, the fourth passage TH4 can overlap the second passage TH2.

[0377] In an optional embodiment, the fourth barrier 654 may restrict the flow of the fluid WT from at least a side surface of the fourth heating unit HU4 toward a side surface of the fifth heating unit HU5. For example, as shown in Fig. 22, the fourth barrier 654 may be connected to both opposing side surfaces of the inner surface of the main body 620 in the thickness direction of the fourth heating unit HU4. Of the surfaces of the fourth barrier 654, the surfaces facing the fourth heating unit HU4 and the fifth heating unit HU5 may have a curved shape, and for example, may have curved surfaces corresponding to the fourth heating unit HU4 and the fifth heating unit HU5.

[0378] A fifth barrier 655 may be disposed between the fifth heating unit HU5 and the sixth heating unit HU6. The fifth barrier 655 may separate the space in which the fifth heating unit HU5 is disposed from the space in which the sixth heating unit HU6 is disposed in at least one region.

[0379] Furthermore, the fluid WT that has flowed in can flow sequentially from the space adjacent to the fifth heating unit HU5 to the space adjacent to the sixth heating unit HU6 via the fifth barrier 655. This allows the fluid WT in the main body 620 to be efficiently heated via the fifth heating unit HU5 and the sixth heating unit HU6.

[0380] The fifth barrier 655 may have a shape extending along the longitudinal direction of the fifth heating unit HU5 and the sixth heating unit HU6, and may have a fifth passage TH5 separated from the inner surface of the main body portion 620 in at least one region in the longitudinal direction, and such fifth passage TH5 may become a passage for the flow of the fluid WT.

[0381] The fifth passage TH5 may not overlap with the fourth passage TH4. For example, the fifth passage TH5 and the fourth passage TH4 may be formed to extend toward opposite ends of both ends of the heating unit HU.

[0382] In an alternative embodiment, the fifth passage TH5 can overlap with the third passage TH3 or the first passage TH1.

[0383] Also, as shown in FIG. 25, the fifth passage TH5 may include a curved hole, specifically an opening shaped like a circle.

[0384] Although not shown, the shape of the fifth passage TH5 may include an opening in the shape of a polygon.

[0385] Furthermore, in an optional embodiment, the fifth passage TH5 may include a groove dug in the bottom to facilitate the flow of the fluid WT through the fifth passage TH5.

[0386] The structure of FIG. 25 may be selectively applied to the first passage TH1 to the fourth passage TH4.

[0387] In an optional embodiment, the fifth barrier 655 may restrict the flow of the fluid WT from at least a side surface of the fifth heating unit HU5 toward a side surface of the sixth heating unit HU6. For example, as shown in Fig. 22, the fifth barrier 655 may be connected to both opposing side surfaces of the inner surface of the main body 620 in the thickness direction of the fifth heating unit HU5. Of the surfaces of the fifth barrier 655, the surfaces facing the fifth heating unit HU5 and the sixth heating unit HU6 may have a curved shape, and for example, may have curved surfaces corresponding to the fifth heating unit HU5 and the sixth heating unit HU6.

[0388] The passage portions, for example, the first passage TH1, the second passage TH2, and the third passage TH3, may have widths to allow the fluid WT to pass through, and in an alternative embodiment, these widths may all be the same.

[0389] The main body 620 may have various shapes and may include at least an inlet 621 for the inflow of the fluid WT and an outlet 622 for the discharge of the fluid WT.

[0390] The inlet 621 and the outlet 622 may be disposed on both sides of the restriction area BTA, such that the fluid WT flowing into the inlet 621 passes through one side of the restriction area BTA, and then passes through an area adjacent to the heating unit HU, where it is heated, and then is discharged to the outlet 622.

[0391] In an optional embodiment, the inlet 621 and the outlet 622 may be disposed on either side of the heating unit HU, thereby improving the heating efficiency and the heating uniformity over the entire area of ​​the fluid WT.

[0392] The body 620 can be formed from a variety of materials. For example, the body 620 can be formed from a durable, lightweight, insulating material. In alternative embodiments, the body 620 can be formed from a plastic material, including various resin families. In other alternative embodiments, the body 620 can include an inorganic material, such as a ceramic.

[0393] Additionally, in other alternative embodiments, the body portion 620 may be formed from a metallic material.

[0394] As another example, the main body 620 may include Teflon resin, which is a fluororesin.

[0395] In an optional embodiment, at least the inner surface of the main body portion 620 adjacent to the fluid WT may include an insulating layer, which may include, for example, an inorganic layer, and may contain inorganic materials including ceramic.

[0396] As another example, an insulating layer containing an organic substance may be formed on the inner surface of the main body 620 that is adjacent to the fluid WT.

[0397] This improves the mutual insulation characteristics with the heating unit part HU, and improves safety when using the electrode-based heating device 600.

[0398] The heating unit section HU may include at least a plurality of heating units HU1, HU2, HU3, HU4, HU5, and HU6, and may include, for example, a first heating unit HU1, a second heating unit HU2, a third heating unit HU3, a fourth heating unit HU4, a fifth heating unit HU5, and a sixth heating unit HU6.

[0399] In an optional embodiment, the first heating unit HU1, the second heating unit HU2, the third heating unit HU3, the fourth heating unit HU4, the fifth heating unit HU5, and the sixth heating unit HU6 may be spaced apart from one another.

[0400] 22, electrolyzed water IW may be disposed inside the first heating unit HU1, and may be disposed so as to be separated from the fluid WT on the outside.

[0401] For example, the electrolyzed water IW may be disposed inside the heat dissipation section 630 of the first heating unit HU1, and the electrolyzed water IW and the fluid WT may be disposed so as to be distinguished from each other via the heat dissipation section 630.

[0402] The first heating unit HU1 can include an electrode section 660 having one or more electrodes.

[0403] At least one region of the electrode portion 660 can be disposed inside the first heating unit HU1, and may be disposed inside the heat dissipation portion 630, for example.

[0404] In addition, the electrode unit 660 can be arranged so as to overlap the electrolyzed water IW so as to heat the electrolyzed water IW in the inner region of the heat dissipation unit 630.

[0405] In addition, the electrode unit 660 may overlap the fluid WT disposed inside the body unit 620 in one direction.

[0406] The electrode section 660 can include multiple electrodes.

[0407] For example, the electrode unit 660 may include a first electrode 661 and a second electrode 662.

[0408] In an optional embodiment, the first electrode 661 and the second electrode 662 may include a first terminal portion 661T and a second terminal portion 662T, respectively, and a power source may be connected via the first terminal portion 661T and the second terminal portion 662T.

[0409] In an optional embodiment, the second heating unit HU2 may have a protective portion 660C formed on the first terminal portion 661T and the second terminal portion 662T as shown.

[0410] The heat dissipation unit 630 of the first heating unit HU1 may be disposed to distinguish between the electrolyzed water IW and the fluid WT. For example, the heat dissipation unit 630 may be located between the electrolyzed water IW and the fluid WT. The heat dissipation unit 630 may also be formed to be spaced apart from the electrode unit 660.

[0411] Also, the structure of FIG. 2 described above may be selectively applied.

[0412] Furthermore, the various heat dissipation section configurations described in the above embodiments can be selectively applied.

[0413] The second heating unit HU2 to the sixth heating unit HU6 may have the same configuration as the first heating unit HU1, and may be modified within a similar range as necessary, so a detailed description will be omitted.

[0414] 22 to 24, the space in the main body 620 through which the fluid WT flows or the space in which the first to sixth heating units HU1, HU2, HU3, HU4, HU5, and HU6 of the heating unit section HU are arranged may include a curved surface.

[0415] For example, the first heating path LA1, the second heating path LA2, the third heating path LA3, the fourth heating path LA4, the fifth heating path LA5, and the sixth heating path LA6 may include curved surfaces, and as a specific example, may include curved surfaces that surround the first heating unit HU1 to the sixth heating unit HU6.

[0416] As a result, the fluid WT is heated in the first heating path LA1, second heating path LA2, third heating path LA3, fourth heating path LA4, fifth heating path LA5, and sixth heating path LA6 while passing around the first to sixth heating units HU1, HU2, HU3, HU4, HU5, HU6 adjacent to them, and can pass through the first heating unit HU1 to the sixth heating unit HU6 sequentially.

[0417] 26 to 28 are exemplary diagrams for explaining the configuration of an electrode-based heating device according to another embodiment of the present invention.

[0418] For convenience of explanation, the heating unit is omitted from FIGS.

[0419] FIG. 26 shows a bottom module 600BU', FIG. 27 shows a top module 600TU', and FIG. 28 shows an insertion section 600MU'.

[0420] The bottom module 600BU' and the top module 600TU' can be combined to form an electrode-based heating device, and in an optional embodiment, an insert 600MU' can be disposed between the bottom module 600BU' and the top module 600TU'.

[0421] The first to fifth barriers can be formed by connecting the first to fifth barrier lower sides 651a' to 655a' in Fig. 26 to the first to fifth barrier upper sides 651b' to 655b' in Fig. 27. For example, the first to fifth barriers 651 to 655 in the above-described embodiments can be formed.

[0422] Furthermore, the first heating path lower side LA11' to the sixth heating path lower side LA61' in Fig. 26 can be connected to the first heating path upper side LA12' to the sixth heating path lower side LA62' in Fig. 27 to form the first to sixth heating paths. For example, the first heating path LA1 to the sixth heating path LA6 in the above-described embodiment can be formed.

[0423] In an alternative embodiment, the inlet 621' and outlet 622' may be formed in the bottom module 600BU' or the top module 600TU', for example, in the bottom module 600BU'.

[0424] The coupling strength between the bottom module 600BU' and the top module 600TU' can be improved via the insert 600MU', thereby reducing or preventing fluid leakage, for example.

[0425] For example, the insert 600MU' may have elasticity and waterproof properties.

[0426] In an optional embodiment, the insertion portion 600MU' may include a side corresponding portion 620MM', a bottom corresponding portion 620MB', and a lower corresponding portion 620BB' to correspond to the main body portion, and each of the side corresponding portion 620MM', the bottom corresponding portion 620MB', and the lower corresponding portion 620BB' may be connected to the bottom module 600BU' and the top module 600TU'.

[0427] The electrode-based heating device of this embodiment can include a heating unit portion having a fluid disposed inside a main body portion and including a plurality of heating units arranged so that at least one region overlaps with the fluid.

[0428] The plurality of heating units are arranged to be spaced apart from each other, and the fluid overlaps with the outer surfaces of the plurality of heating units, so that the fluid can be easily heated by the heating units. In addition, the fluid can be disposed between the plurality of heating units, so that the efficiency of heating the fluid can be improved.

[0429] Furthermore, a barrier section can be formed between the plurality of heating units, and a passage section can be formed in one region of the barrier section so that a fluid can pass through.

[0430] For example, the barrier portion may include a plurality of barriers, and the passage portions of each barrier may be formed alternately with each other.

[0431] This structure allows fluid to easily move between the heating units and the adjacent spaces, which are separated from each other by the barrier portions.

[0432] In addition, depending on the specific configuration of the passage, the fluid may flow in one direction and be heated sequentially by the heating units of the heating unit section. For example, the fluid may be heated while flowing along the sequentially arranged heating units, and the direction of the fluid flow may be reversed each time the fluid moves to an adjacent heating unit.

[0433] This allows a smooth flow of fluid to be generated along each heating unit, improving the efficiency of heating the fluid.

[0434] Meanwhile, the inner surface of the fluid flow region may include a curved surface, specifically a shape that surrounds the heat dissipation portion, so that the fluid flows while effectively contacting the heat dissipation portion of each heating unit as it passes through the heating path, thereby easily heating the fluid and improving the thermal efficiency of the electrode-based heating device and increasing the fluid heating rate.

[0435] FIG. 29 is a schematic plan view illustrating an electrode-based heating device according to another embodiment of the present invention.

[0436] FIG. 30 is a schematic plan view of the electrode-based heating apparatus of FIG. 29 with the top module 700TU removed.

[0437] The electrode-based heating device 600 of this embodiment may include a main body portion 620 and a heating unit portion HU.

[0438] The electrode-based heating device 700 of this embodiment may have a configuration in which a top module 700TU is connected to a bottom module 700BU, for example, via a fastening member BTN, and may be separated as needed, for example, after the fluid WT is removed.

[0439] An inflow member 721P through which the fluid WT flows into the inside of the main body 720 may be formed to protrude from the outer surface of the main body 720.

[0440] In an optional embodiment, the inflow member 721P may be formed in a form that can be attached to and detached from the main body portion 720, and may be formed thicker than adjacent regions for convenience in this process, and may have an attachment portion 721PB adjacent to the main body portion 720, and as an example, an insert member GT may be placed therebetween to reduce or prevent outflow or leakage of the fluid WT.

[0441] The discharge member 722P, through which the fluid WT is discharged to the outside of the main body part 720, may be formed to protrude from the outer surface of the main body part 720.

[0442] In an optional embodiment, the discharge member 722P may be formed in a form that can be attached to and detached from the main body portion 720, and may be formed thicker than adjacent regions for convenience in this process, and may have a connecting portion 722PB adjacent to the main body portion 720, and as an example, an insert member GT may be placed therebetween to reduce or prevent the outflow or leakage of the fluid WT.

[0443] The barrier portion 750 may be positioned to distinguish between the multiple heating units HU1, HU2, HU3, HU4, HU5, and HU6.

[0444] For example, the barrier portion 750 may include a first barrier 751, a second barrier 752, a third barrier 753, a fourth barrier 754, and a fifth barrier 755, which may be arranged spaced apart from one another in sequence.

[0445] In addition, the first barrier 751, the second barrier 752, the third barrier 753, the fourth barrier 754, and the fifth barrier 755 can be formed with a first passage TH1, a second passage TH2, a third passage TH3, a fourth passage TH4, a fifth passage TH5, and a sixth passage TH6, respectively.

[0446] The specific details of the barrier unit 750 may be the same as or similar to the barrier unit 650 of the above-described embodiment. Note that various configurations of the above-described embodiment may be selectively applied, and therefore detailed description thereof will be omitted.

[0447] The heating unit section HU may include at least a plurality of heating units HU1, HU2, HU3, HU4, HU5, and HU6, and may include, for example, a first heating unit HU1, a second heating unit HU2, a third heating unit HU3, a fourth heating unit HU4, a fifth heating unit HU5, and a sixth heating unit HU6.

[0448] At least one of the first heating unit HU1, the second heating unit HU2, the third heating unit HU3, the fourth heating unit HU4, the fifth heating unit HU5, and the sixth heating unit HU6 may have an elongated shape so as to be connected to one side of the main body 720 and one side opposite thereto.

[0449] In an optional embodiment, at least one of the first, second, third, fourth, fifth, and sixth heating units HU1, HU2, HU3, HU4, HU5, and HU6 may be connected to an inner surface of the main body 720, for example, an inner surface in a direction in which the fluid WT flows in or out, and may be connected via an inner coupling region IBT, for example. The electrolyzed water in the heating unit and the fluid WT can be separated from each other via the inner coupling region IBT.

[0450] In an optional embodiment, at least one of the first heating unit HU1, the second heating unit HU2, the third heating unit HU3, the fourth heating unit HU4, the fifth heating unit HU5, and the sixth heating unit HU6 may be connected to an outer surface of the main body 720, for example, an outer surface facing in a direction opposite to the direction in which the fluid WT flows in or out. For example, the connection may be made via an outer coupling region OBT. The outer coupling region OBT may separate the electrolyzed water in the heating unit from the fluid WT. As another example, a terminal region of an electrode unit in the heating unit may be connected to the outer coupling region OBT, or may be connected to the outside via the outer coupling region OBT, or may be connected to a terminal connector of a power supply unit.

[0451] In an optional embodiment, an insert OGT can be placed to reduce or prevent the strength of the bond and leakage of the fluid WT.

[0452] The first heating unit HU1, the second heating unit HU2, the third heating unit HU3, the fourth heating unit HU4, the fifth heating unit HU5, and the sixth heating unit HU6 are the same as those described in the above-mentioned embodiments or can be selectively applied, so detailed explanations will be omitted.

[0453] The electrode-based heating device of this embodiment may have inlet and outlet members that are elongated to facilitate the inlet and outlet of fluids into and out of the body.

[0454] In addition, the heating unit may have a structure in which a plurality of heating units are connected to both opposing inner surfaces of the main body in a long extended manner.

[0455] This increases the contact area between the fluid inside the body and the heating unit, allowing for effective heating of the fluid within the heating path, reducing or preventing uneven heating or abnormal cooling of the fluid, and thus facilitating the realization of an electrode-based heating device with improved thermal efficiency.
