In the description of the embodiments of the present application, it should be noted that the terms "width direction", "length direction", "transverse direction", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only used for convenience in describing the embodiments of the present application and simplifying the description, but do not indicate or imply that the referred devices or elements must have a specific orientation, be configured and operated in a specific orientation, and thus, should not be construed as limiting the embodiments of the present application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

An embodiment of the utility model provides an electrolytic assembly 1000, referring to fig. 1, fig. 2, fig. 3 and fig. 4, including an electrolytic electrode, a heating tube 2 and at least one connecting device 3.

The electrolysis electrode includes an electrolysis cathode 11 and an electrolysis anode 12. It can be understood that the electrolytic cathode 11 and the electrolytic anode 12 are insulated from each other, i.e. any position of the electrolytic cathode 11 and the electrolytic anode 12 is not in contact, so as to ensure the normal operation of the electrolytic electrodes.

The arrangement form of the electrolytic cathode 11 and the electrolytic anode 12 is not limited. Illustratively, electrolytic cathode 11 is generally located in one plane, electrolytic anode 12 is generally located in another plane, and electrolytic cathode 11 and electrolytic anode 12 are stacked.

The specific structural shape of the electrolytic cathode 11 is not limited, and may be, for example, a plate-like structure, a mesh-like structure, a tooth-like structure, or the like, and is not limited herein.

The specific structural shape of the electrolytic anode 12 is not limited, and for example, the structure may be a plate-like structure, a mesh-like structure, a tooth-like structure, or the like, and is not limited herein.

The heating tube 2 includes a metal tube shell and a heating element located within the metal tube shell, the heating element refers to a heat source of the heating tube 2, which may be a heating wire, or other element that can generate a heat source, and in some embodiments, the heating element is a heating wire. In the 2 working processes of heating pipe, the heater block generates heat, and the heat transfer that the heater block sent is to the metal tube shell, and the metal tube shell gives around water liquid with heat transfer, realizes the heating to water liquid.

It should be noted that the heating element is electrically insulated from the metal envelope, i.e. there is only heat transfer between the heating element and the metal envelope, and no current flows. For example, the metal envelope is filled with an insulating powder, such as magnesium oxide powder. The insulating powder plays a role of an insulating medium, a role of fixing a heating part and a role of transferring heat.

Referring to fig. 1, 3 and 4, the heating tube 2 includes at least two first tubes 21 spaced apart from each other, wherein one of the first tubes 21 is located at one side of the other first tube 21 in the transverse direction, that is, the two first tubes 21 are substantially arranged side by side. The electrolysis electrode is disposed between the two first tubes 21. The two first tubes 21 provide a receiving space for the electrolysis electrodes, so that the structure of the electrolysis assembly 1000 can be more compact.

In some embodiments, the electrolysis electrodes are spaced apart from the first tubes 21, i.e., the electrolysis cathode 11 is not in direct contact with the first tubes 21, and the electrolysis anode 12 is not in direct contact with the first tubes 21, so as to avoid impact and friction between the electrolysis electrodes and the heating tube 2.

Referring to fig. 1, 3 and 4, the heating pipe 2 includes a bent second pipe 22, the second pipe 22 is connected between two first pipes 21, and the second pipe 22 can be made into various shapes.

The metal envelope of the heating tube 2 is electrically connected to the electrolytic cathode 11. That is to say, the potentials of the electrolytic cathode 11 and the metal tube shell of the heating tube 2 are the same, and the electrolytic cathode 11 forms cathodic protection to the metal tube shell, so that the metal tube shell is not easy to corrode, and the service life of the electrolytic component 1000 is prolonged.

Wherein,cathodic protection means that the metal envelope of the heating tube is protected from Fe²⁺Conversion to Fe³⁺Thereby generating scale.

Referring to fig. 1 and 6, the connecting device 3 comprises a pair of fastening tapes 31, the electrolytic cathode 11 and the electrolytic anode 12 are clamped between the pair of fastening tapes 31, and the two fastening tapes 31 restrain the electrolytic cathode 11 and the electrolytic anode 12. In particular, one of the fastening strips 31 is located on the side of the electrolytic cathode 11 facing away from the electrolytic anode 12, and the other fastening strip 31 is located on the side of the electrolytic anode 12 facing away from the electrolytic cathode 11. The two fastening belts 31 play a good role in clamping and positioning the electrolysis electrode.

The fastening tape 31 is insulated from the electrolytic anode 12.

The connecting device 3 is connected with the heating pipe 2 and the electrolysis electrode and forms a stress support for the electrolysis electrode. That is, the electrolytic cathode 11 and the electrolytic anode 12 are assembled to the heating tube 2 by the connection means 3, the connection means 3 having a certain rigidity and structural strength, the connection means 3 carrying at least part of the weight of the electrolytic electrode, the connection means 3 transferring the weight it bears and its own weight to the heating tube 2.

Referring to fig. 1 and 6, the fastening band 31 includes a body portion 311 and fastening portions 312 disposed at two ends of the body portion 311, wherein the fastening portions 312 are fastened to the first tube 21.

Along the length of the first tube 21, the two fastening sections 312 on the same first tube 21 are offset. For example, the fastening section 312 at the first end of the first fastening tape 31 and the fastening section 312 at the first end of the second fastening tape 31 are engaged with one of the first tubes 21, and the two fastening sections 312 clamp at least a portion of the first tube 21 and are arranged to be offset in the longitudinal direction. The fastening section 312 at the second end of the first fastening tape 31 and the fastening section 312 at the second end of the second fastening tape 31 are fastened to at least a portion of the other first tube 21, and the two fastening sections 312 clamp the first tube 21 and are arranged along the length direction in a staggered manner.

The longitudinal offset means that the lengths of the fastening tapes 31 in the longitudinal direction of the heating tube 2 do not overlap.

It is understood that the formation of scale on the heating tube is a dynamic process, and after the formation of the scale layer, part of the scale will fall off under the washing and dewatering operation conditions of the clothes treatment equipment.

In the correlation technique, two lock joint sections roughly set up along same circumference of first body, form less clearance between the tip of two lock joint sections, and this clearance is a dead angle, and the incrustation scale is piled and is difficult for droing in dead angle department, and the incrustation scale is easy more to be deposited thickly. After the scale deposit, the heat dissipation of the heating pipe can be influenced.

The metal case of the heating pipe 2 is generally made of austenitic stainless steel, and the metallographic structure of the austenitic stainless steel at room temperature is supercooled austenite. In the related technology, the accumulated scale is attached to the surface of the heating pipe, so that the heating pipe cannot radiate heat in time, the temperature of the heating pipe at the local part is very high, and at high temperature, alloy elements doped with chromium, nickel and the like which are dissolved in iron-carbon alloy in a solid manner are enriched, segregated and the like, so that the metallographic structure of austenitic stainless steel is changed, the performance of austenitic stainless steel is changed, the austenitic stainless steel is corroded, and the corrosion accumulated to a certain degree can cause the metal pipe shell to be rusted and worn to lose efficacy.

The electrolytic component 1000 of the embodiment of the application can generate hydroxyl radicals with strong oxidation activity by electrolyzing water through the electrolytic electrode so as to sterilize, and can also heat liquid to a required temperature through the heating pipe 2.

The electrolytic component 1000 of the embodiment of the application, because two buckling sections 312 on the same first pipe 21 are staggered, therefore, the joint of the two buckling sections 312 and the first pipe 21 does not form a dead angle, a semi-open space is formed, and the scale is not easy to accumulate, thereby being beneficial to heat dissipation of the heating pipe 2 and prolonging the service life of the heating pipe 2.

Illustratively, the first tube body 21 has a clamping section along the length of the heating tube 2, which clamping section is indicated by the length of the dashed box in fig. 1, see fig. 1. The fastening section 312 of each connecting device 3 is disposed in the clamping section. For example, when the number of the connecting device 3 is only one, the fastening section 312 of the first end of each fastening tape 31 of the connecting device 3 is located at the clamping section of one of the first tubes 21, and the fastening section 312 of the second end of each fastening tape 31 is located at the clamping section of the other first tube 21. When the number of the connecting devices 3 is plural, the fastening section 312 of the first end of each fastening tape 31 of all the connecting devices 3 is located at the fastening section of one of the first pipe bodies 21, and the fastening section 312 of the second end of each fastening tape 31 of all the connecting devices 3 is located at the fastening section of the other first pipe body 21.

It should be noted here that the clamping section is not strictly limited but may be widened to an appropriate size at both ends of the section where both contact.

Illustratively, the electrical power density of the clamping section is less than the electrical power density of the remaining sections. Wherein the power density comprises: the heating power of the heating element per unit length of the heating tube 2 is divided by the surface area per unit length of the heating tube 2.

The heating power of the heating member per unit length of the heating pipe 2 is related to the effective length of the heating member, and the longer the effective length of the heating member per unit length of the heating pipe 2 is, the higher the heating power of the heating member per unit length of the heating pipe 2 is. That is, the electric power density here refers to the electric power density of the heating member in the heating pipe 2.

In some embodiments, the heating member is not helically wound in the clamping section, but is arranged in a substantially straight line, and the heating member is helically wound in the remaining section to increase the effective length of the heating member.

The electrolytic component 1000 of this embodiment, through reducing the electric power density of joint section, suitably increase the electric power density of other sections, so, under the condition of not sacrificing the total power of heating pipe 2, reduce the temperature of joint section for the local temperature in the joint region of first body 21 can not reach the temperature that the super-cooled austenite metallographic structure changes, promotes the life of heating pipe 2. Illustratively, the power density of the clamping section does not exceed 1/2 of the power density of the remaining sections. In this way, the total power of the heating pipe 2 can be taken into account, and the local power of the first pipe body 21 can be controlled within an appropriate range.

Illustratively, the clamping section has a power density of no more than 6W/cm²(watts per square centimeter) which, even in the presence of scale, does not increase the local temperature of the clamping section. The power density of the rest section is 8W/cm²～15W/cm²For example, 8W/cm²、10W/cm²、10.2W/cm²、10.6W/cm²、11W/cm²、11.5W/cm²、12W/cm²、13W/cm²、14W/cm²、15W/cm²And the like. In this embodiment, the power density of the remaining section of the heating tube 2 is controlled to 15W/cm²Hereinafter, even if scale exists, the local temperature does not exceed 500 ℃.

Illustratively, the length of the clamping section is 1mm to 50 mm. For example, 1mm, 3mm, 8mm, 10mm, 12mm, 15mm, 20mm, 24mm, 30mm, 33mm, 38mm, 42mm, 45mm, 50mm, and the like. Therefore, the clamping sections can be intensively arranged in a low power density area, and arrangement of heating parts is facilitated.

Illustratively, the length of the clamping section is 3mm to 30 mm. For example, 3mm, 8mm, 10mm, 12mm, 15mm, 20mm, 24mm, 30 mm. In the embodiment, the clamping sections are concentrated in a relatively narrow range, so that the phenomenon that the overall length of the heating pipe is obviously lengthened due to the overlong length of the clamping sections is avoided.

The number of the connecting means 3 may be one or more. Wherein a plurality means two or more.

In the embodiment where the number of the connection devices 3 is plural, the plural connection devices 3 are arranged at intervals along the length direction of the first pipe body 21. In this way, each connecting device 3 forms at least two support positions in the longitudinal direction for the electrolysis electrode, thereby improving the reliability of supporting the electrolysis electrode.

Illustratively, referring to fig. 1, 4 and 5, the connecting device 3 includes a fastening member 33, the fastening member 33 penetrates through the body sections 311 of the pair of fastening tapes 31, the electrolytic cathode 11 and the electrolytic anode 12, and the fastening member 33 applies a clamping force to the two body sections 311.

The specific type of fastener 33 is not limited, for example, a rivet, a bolt.

It should be noted that the fastening member 33 does not contact the electrolytic anode 12, and thus, the electrolytic anode 12 and the electrolytic cathode 11 are not short-circuited.

The manner of electrical connection between the metal case of the heating tube 2 and the electrolytic cathode 11 is not limited, and may be realized by a metal wire connection, for example.

Illustratively, the fastening element 33 electrically conductively connects the two fastening strips 31, and the connecting device 3 electrically conductively connects the heating tube 2 and the electrolysis cathode 11. In this embodiment, the connecting means 3 not only serves a physical restraint but also functions as an electrical conductor. For example, the fastening belt 31 is a sheet metal part or a metal part, so that the structure strength is better and the electric conduction is also considered.

It should be noted that, for the same fastening tape 31, the main body segments 311 and the fastening tapes 31 at the two ends thereof are not located on the same line, so that the main body segments 311 of the two fastening tapes 31 have overlapping regions and the fastening segments 312 are staggered. Wherein the fastener 32 extends through the overlapping region.

Illustratively, a pair of fastening tapes 31 are arranged crosswise in projection parallel to the lamination plane of the electrolytic anode 12 and the electrolytic cathode 11. An overlap region is formed at the intersection location, through which the fastener 33 passes. Thus, the acting force of the two fastening belts 31 on the first tube 21 can be balanced, and in the process of tightening the fastener 33, the two fastening belts 31 cannot form obvious shearing force on the local part of the first tube 21.

Illustratively, the body segments 311 of a pair of fastening strips 31 have overlapping regions in a projection parallel to the lamination plane of the electrolytic anode 12 and the electrolytic cathode 11, it being understood that the projections of the fastening segments 312 are offset from each other. The overlapping region extends in the width direction of the electrolytic electrode, that is, the overlapping region has a longer length. Illustratively, the number of the fasteners 33 is multiple, and the multiple fasteners 33 are arranged at intervals along the extending direction of the overlapping region, so that the multiple fasteners 32 are arranged in the overlapping region, and the fastening reliability is improved.

The width direction of the electrolytic electrode is perpendicular to the length direction of the first tube 21 and perpendicular to the stacking direction of the electrolytic electrode.

Illustratively, a pair of fastening segments 312 to the same first tube 21 are located on opposite sides of an extension of the overlapping region. In this way, each fastening section 312 is arranged as close to the extension line as possible, the structure is compact, and the installation space occupied by the connecting device 3 in the length direction of the first pipe body 21 is reduced.

Illustratively, referring to fig. 6, two fastening segments 312 of the same fastening strip 31 are located on opposite sides of an extension line L of the overlapping region. In this way, the two fastening bands 31 can be arranged in a substantially crossed manner, so that the acting force of the fastening sections 312 of the two fastening bands 31 on the first tube 21 is balanced, and the two fastening bands 31 do not form a significant shearing force on a part of the first tube 21 during the process of tightening the fastener 33.

The shape and material of the first fastening tape 31 may be the same as or different from those of the second fastening tape 31.

Illustratively, the fastening tapes 31 are made of the same material and shape, for example, sheet metal, and have the same shape. Therefore, the fastening belts 31 can be used universally, so that the generalization rate of parts is improved, and the stock pressure of stagnant materials is reduced.

In some embodiments, the electrolytic assembly 1000 includes the first insulating member 41, and at least a portion of the first insulating member 41 is sandwiched between the electrolytic cathode 11 and the electrolytic anode 12, so as to avoid short circuit between the electrolytic cathode 11 and the electrolytic anode 12, and improve reliability of the electrolytic electrode.

The number of the protruding columns 412 may be one or more.

The first insulating member 41 may be made of a material having a certain damping performance, such as rubber, silicone, or the like.

In an embodiment, referring to fig. 5, the end surface of the protruding pillar 412 protrudes from the surface of the side of the electrolytic anode 12 away from the electrolytic cathode 11, and one of the fastening bands 31 abuts against the end surface of the protruding pillar 412, so that a space is formed between the fastening band 31 and the electrolytic anode 12, thereby preventing the electrolytic anode 12 from being electrochemically corroded.

In one embodiment, referring to fig. 1, 2, 4 and 5, the electrolytic assembly 1000 further includes a second insulating member 42, and the second insulating member 42 is sandwiched between one of the fastening tapes 31 and the electrolytic anode 12.
