Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, in particular to a dishwasher. BACKGROUND

[0002] At present, many dishwasher products on the market have disinfection function, and part of the dishwasher is prepared by electrolyzing tap water or salt water through direct current electrolysis technology to prepare disinfection water, and then the disinfection water is sprayed on the surface of tableware for disinfection. However, in general, the base is usually used as the centralized installation area of various components, and is used for bearing, so the electrolysis water tank is also mostly arranged at the base position.

[0003] However, the installation and layout of various key components such as water pump in the base area need enough space, after the electrolysis water tank occupies part of the space of the base, only the installation and layout of the key components can be changed, so that these components are difficult to be laid out according to the optimal structure and function requirements, thereby affecting the overall assembly efficiency and equipment performance of the dishwasher. SUMMARY

[0004] Therefore, the present application provides a dishwasher to solve the technical problem that the electrolysis water tank occupies the installation and layout space of the key components after being arranged at the base in the prior art.

[0005] In a first aspect, the present application provides a dishwasher, which comprises:

[0006] The inner container is provided with a washing space.

[0007] The water tank mechanism comprises an electrolysis water tank and an electrode assembly.

[0008] The electrolysis water tank is in a flat structure and is arranged outside the side wall of the inner container, and the flat structure is matched with the side wall of the inner container; and the electrolysis water tank is provided with a water inlet and a water outlet, and the water outlet is communicated with the inner container.

[0009] The electrode assembly is arranged in the electrolysis water tank.

[0010] Beneficial effects: the electrolysis water tank is arranged in a flat structure and matched with the side wall of the inner container in the embodiment, so that the flat structure can closely fit the planar profile of the side wall of the inner container, does not occupy the core area of the base, and reserves sufficient layout space for the water pump, pipeline and other key components, thereby avoiding the problem of occupying the space of the base. Moreover, the matched shape of the flat structure and the side wall greatly improves the space utilization rate of the machine body, avoids the increase of the volume of the machine body caused by the protruding water tank. At the same time, the direct communication of the water outlet with the inner container can shorten the conveying path of the electrolyzed disinfection water, reduce the stagnation loss of water flow in the pipeline, and ensure that the high-concentration disinfection water can quickly enter the washing space, thereby improving the disinfection efficiency of tableware.

[0011] In an alternative embodiment, the electrolysis water tank is detachably connected to the side wall of the inner container.

[0012] Beneficial effects: The present application detachably connects the electrolysis water tank to the side wall of the inner container, without the need for welding operations. The electrolysis water tank can be fixed to the side wall of the inner container through convenient methods such as buckles and screws, thereby reducing the assembly process and improving the assembly efficiency. Moreover, during maintenance, the water tank can be removed by only detaching the connecting piece without disassembling the entire machine or damaging the structure. Whether it is water tank replacement or subsequent maintenance of the electrode assembly, the maintenance time and cost can be reduced. At the same time, if the merchant subsequently launches an electrolysis water tank with better performance, the user can upgrade without replacing the entire machine, thereby prolonging the life cycle of the dishwasher and improving the cost performance of the product.

[0013] In an alternative embodiment, the electrolysis water tank is provided with a mounting port, one end of the electrode assembly extends into the electrolysis water tank through the mounting port, and the other end of the electrode assembly is provided with a cover body suitable for closing the mounting port.

[0014] Beneficial effects: In this embodiment, the electrode assembly is mounted into the electrolysis water tank through the mounting port, and the cover body can close the mounting port. During assembly, the electrode assembly can be directly inserted into the electrolysis water tank to complete the installation. Compared with the traditional installation inside the electrolysis water tank, the installation steps can be significantly reduced. Moreover, the mounting port provides a precise positioning reference for the electrode assembly, and the electrode can be guided into place along the mounting port when it is extended, avoiding the deviation that occurs during traditional assembly and improving the electrolysis stability. Further, during maintenance, the electrode assembly can be removed from the mounting port by only opening the cover body, without disassembling the water tank. The electrode can be quickly removed for deep cleaning or replacement, greatly simplifying the electrode cleaning and replacement process.

[0015] In an alternative embodiment, the electrode assembly comprises:

[0016] an electrode group consisting of at least one electrode sheet;

[0017] a mounting seat provided with a cover body; the mounting seat is provided with a fixing groove on the side away from the cover body; the number of fixing grooves corresponds to the number of electrode sheets;

[0018] One end of each electrode sheet is embedded in the corresponding fixing groove and connected to the mounting seat, and the other end of each electrode sheet is suitable for extending into the electrolysis water tank.

[0019] Beneficial effects: In traditional electrode assemblies, electrode sheets are often fixed in a scattered manner, such as being directly welded to the inner wall of the water tank. This will cause uneven spacing between the electrode sheets, and the electrode sheets are easy to shake under the impact of water flow during electrolysis, resulting in uneven discharge and low efficiency during electrolysis. The number of fixing slots in the embodiment corresponds to the number of electrode sheets, so that each electrode sheet can be embedded in a dedicated fixing slot, and the spacing can be strictly controlled by the preset size of the fixing slot, ensuring uniform discharge of the electrode group and improving the efficiency of disinfectant water preparation. Further, the mounting seat provides a unified support carrier for the electrode group, and the electrode sheets are firmly connected to the mounting seat through the fixing slots, avoiding the shaking and displacement of the electrode sheets and reducing the risk of short circuit. Further, since the mounting seat and the cover are integrated, the electrode assembly can be connected to the water tank as a whole through the mounting seat, without the need to fix each electrode sheet separately, simplifying the assembly process of the electrode and the water tank and improving production efficiency.

[0020] In an alternative embodiment, the electrode assembly further comprises:

[0021] The connecting sheet is connected to the mounting seat;

[0022] The connecting sheet is provided with a connecting slot on the side close to the electrode group, and the number of connecting slots corresponds to the number of electrode sheets;

[0023] Each electrode sheet is provided with a notch matched with the connecting slot, and each electrode sheet is connected to the corresponding connecting slot through the notch.

[0024] Beneficial effects: The connecting sheet in the embodiment is connected to all electrode sheets through the connecting slots, forming an integrated electrode unit, which can simplify the assembly process. Furthermore, the cooperation of the connecting slot and the notch further strengthens the positioning of the electrode sheet. On the basis of the fixing slot, the connecting slot forms a constraint from the other side of the electrode sheet to prevent the electrode sheet from shifting in the up-down and front-back directions. Double positioning ensures long-term stability of the electrode spacing, avoiding fluctuations in electrolysis efficiency due to changes in spacing. Furthermore, the clamping structure is more easily disassembled than welding, and if a single electrode sheet is damaged, it can be directly removed and replaced from the connecting slot without damaging the connecting sheet or other electrode sheets, reducing maintenance costs.

[0025] In an alternative embodiment, the electrode assembly further comprises:

[0026] The limiting piece is arranged on the outer periphery of the electrode group;

[0027] Under the action of external force, the limiting piece has a first position of buckling to the outer periphery of the electrode group and fixing all the electrode sheets, and a second position of being separated from the outer periphery of the electrode group.

[0028] Beneficial effects: In this embodiment, when the limiting piece is in the first position, it is buckled around the outer periphery of the electrode group to form a ring-shaped constraint, which can prevent the electrode sheet from expanding outward and deforming, ensure that the electrode gap always meets the design requirements, and avoid the problem of reduced electrolysis efficiency caused by increased spacing. Moreover, the limiting piece can resist the impact of water flow on the outer periphery of the electrode sheet, reduce the shaking of the electrode sheet, and reduce the risk of short circuit. Further, since the limiting piece can be detached from the electrode group in the second position, it will not affect the disassembly of the electrode assembly, and the electrode sheet can be removed by switching to the second position during maintenance, which is flexible and avoids the problem of difficult disassembly of traditional fixed limiting structures.

[0029] In an alternative embodiment, the limiting piece comprises:

[0030] at least one pair of limiting frames, respectively arranged on both sides of the electrode group;

[0031] Under the action of external force, the two limiting frames have a first position in which they are buckled to the outer periphery of the electrode group and fix all the electrode sheets, and a second position in which they are mutually detached from the outer periphery of the electrode group.

[0032] Beneficial effects: In this embodiment, the limiting frames are buckled from both sides of the electrode group rather than being integrally fitted, so disassembly does not require sliding along the axial direction, especially in scenarios where the internal space of the water tank is small, the limiting frames can be separated to the two sides to complete the detachment, which requires less operating space and is suitable for the compact environment of flat water tanks. Moreover, compared to unilateral limiting, symmetrical buckling from both sides can form balanced fixing force, and the limiting frames on both sides can simultaneously apply constraints from the front-to-back direction of the electrode group, avoiding the electrode sheet from shifting to one side and further improving the stability of the electrode spacing. Further, since multiple pairs of limiting frames are provided, if one of the limiting frames is damaged, only a single component needs to be replaced, without the need for overall replacement, reducing maintenance costs.

[0033] In an alternative embodiment, the limiting frame is provided with a groove, the electrode sheet is provided with an opening, and the opening and the groove are correspondingly arranged; in the first position, the electrode sheet is embedded in the groove through the opening.

[0034] Beneficial effects: In this embodiment, the opening of each electrode sheet corresponds to the groove of the limiting frame, and after fitting, the electrode sheet can be restricted from shifting, enabling precise alignment of the limiting frame and the electrode sheet. Moreover, the structure of the opening embedded in the groove can further restrict the displacement of the electrode sheet, in addition to the peripheral constraint of the limiting frame, the groove can also catch the electrode sheet from various directions to prevent the electrode sheet from shaking perpendicular to the buckling direction of the limiting frame, forming a multi-dimensional fixation, which is particularly suitable for scenarios where the water flow direction is complex during electrolysis. Further, the cooperation of the groove and the opening can also simplify the assembly process, and during assembly, the opening and the groove can be quickly positioned without the need for repeated adjustment of the position of the limiting frame, improving assembly efficiency.

[0035] In an alternative embodiment, each pair of limiting racks are connected to each other when buckled to the outer periphery of the electrode group, and each pair of limiting racks are disconnected from each other after being disconnected.

[0036] Beneficial effects: In this embodiment, the connected pair of limiting racks can form an overall restraint frame, which can resist greater water flow impact or vibration, avoid unilateral loosening, and ensure continuous restraint of the electrode group. Moreover, since the limiting racks can directly limit the overall outer periphery of the electrode group when buckled, it can prevent individual electrode sheets from being displaced due to vibration or water flow impact. Further, during maintenance, only the connection between the limiting racks needs to be released, such as unfastening the buckles or screws, so that the two limiting racks can be removed separately without affecting the removal of the electrode sheets, avoiding difficult disassembly, thereby improving maintenance efficiency.

[0037] In an alternative embodiment, a plurality of pairs of limiting racks are uniformly arranged on the electrode group along the extension direction of the electrode group.

[0038] Beneficial effects: In this embodiment, the uniformly distributed multiple pairs of limiting racks can divide the long electrode group into multiple short segments, so that each segment is restrained, thereby avoiding the middle region of the electrode group from sagging or deforming, and thus avoiding the entire electrode group from deforming, thereby ensuring that the spacing of all electrode sheets is uniformly arranged. Moreover, segmented fixation can disperse the force, and the force generated by water flow impact or vibration can be borne by multiple pairs of limiting racks, avoiding damage caused by excessive force on a single pair of limiting racks, thereby prolonging the service life of the limiting racks. Further, the uniform distribution of multiple pairs of limiting racks can also improve the fatigue resistance of the electrode group. During long-term electrolysis, the micro-vibration of the electrode sheets will accumulate fatigue, and multiple pairs of limiting racks can reduce the vibration amplitude of each electrode sheet, thereby reducing the risk of fatigue deformation.

[0039] In an alternative embodiment, the electrode assembly is provided with a first electrical connection end and a second electrical connection end, and the first electrical connection end and the second electrical connection end are connected to the power supply end of the dishwasher; the polarity of the first electrical connection end and the second electrical connection end is reversed every predetermined time.

[0040] Beneficial effects: In this embodiment, the polarity of the electrode assembly can be reversed every certain period of time. When the polarity of the current is reversed, the original anode becomes a cathode, and the original cathode becomes an anode, so that the scale on the surface of the anode can be dissolved due to oxidation, and the scale on the surface of the cathode can be removed due to reduction, thereby achieving automatic descaling without manual disassembly and cleaning.

[0041] In an alternative embodiment, the inside of the electrolytic water tank is provided with a first overflow port and a breather, the breather is provided with a second overflow port, one end of the second overflow port is communicated with the first overflow port through an overflow pipeline, and the other end of the second overflow port is communicated with the inner container.

[0042] Beneficial effects: The first overflow port and the second overflow port are arranged in the embodiment. When the water inflow is too much, the water first flows into the overflow pipeline through the first overflow port, and then flows into the inner container through the second overflow port, so that the water can be prevented from leaking out of the electrolytic water tank and damaging the circuit, the side plate and other components in the machine body. Meanwhile, the overflow water is recycled to the inner container to participate in the subsequent washing and disinfection process, realizes water resource recycling, and solves the problem of waste of traditional overflow drainage.

[0060] At present, many dishwashers on the market have disinfection function, and part of the dishwashers are prepared by electrolyzing tap water or salt water through direct current electrolysis technology to prepare disinfection water, and then the disinfection water is sprayed to the surface of tableware for disinfection. However, in general, the base is usually used as the centralized installation area of various components, and is used for bearing, so the electrolysis water tank 21 is also mostly arranged at the base position.

[0061] However, the installation and layout of various key components such as the water pump in the base area require sufficient space. After the electrolytic water tank 21 occupies part of the space of the base, only the installation and layout of the key components can be changed, so that these components are difficult to be laid out according to the optimal structure and functional requirements, thereby affecting the overall assembly efficiency and equipment performance of the dishwasher.

[0062] Therefore, the present application provides a dishwasher to solve the technical problem that the electrolytic water tank 21 occupies the installation and layout space of the key components after being arranged in the base in the prior art.

[0063] The embodiments of the present application will be described below in conjunction with Figures 1 to 7 .

[0064] As shown in Figures 1 to 7 , according to the embodiments of the present application, on the one hand, the present application provides a dishwasher, which comprises an inner container 10 and a water tank mechanism 20.

[0065] Specifically, in the present embodiment, the inner container 10 is provided with a washing space, and the water tank mechanism 20 comprises an electrolytic water tank 21 and an electrode assembly 22. The electrolytic water tank 21 is in a flat structure and is arranged outside the side wall 11 of the inner container 10, and the flat structure is in harmony with the side wall 11 of the inner container 10.

[0066] The inner container 10 is usually in a rectangular structure, so in the present embodiment, the electrolytic water tank 21 can be arranged in a plate-shaped rectangular structure, and the electrolytic water tank 21 is directly attached to the outer side wall 11 of the inner container 10, so as to only occupy part of the space of the side wall 11 of the inner container 10, without occupying the space of the base. At the same time, since the size of the electrolytic water tank 21 is relatively thin, the overall thickness of the electrode assembly 22 also needs to be relatively small. In order to ensure the electrolysis efficiency, the overall extension size of the electrode assembly 22 can be increased, so as to increase the discharge area. In addition, a high-power discharge device can also be adapted, so that the time for preparing disinfectant water by electrolysis is greatly reduced.

[0067] Further, in the present embodiment, the electrolytic water tank 21 is provided with a water inlet 211 and a water outlet 212, and the water outlet 212 is in communication with the inner container 10, and the water inlet 211 is in communication with a water source, which can be, for example, a water inlet pipeline of the dishwasher or an external tap. At the same time, the electrode assembly 22 is arranged in the electrolytic water tank 21, and electrolysis can be carried out after the water inlet of the electrolytic water tank 21 is completed.

[0068] In this way, the electrolysis water tank 21 is arranged in a flat structure and fits the side wall 11 of the inner container 10, so that the flat structure closely fits the planar profile of the side wall 11 of the inner container 10, does not occupy the core area of the base, and reserves sufficient layout space for key components such as the water pump and pipeline, thereby avoiding the problem of occupying the space of the base. Moreover, the flat structure fitting the side wall 11 greatly improves the space utilization rate inside the machine body, avoiding the increase in the size of the machine body caused by the protruding water tank. At the same time, directly connecting the water outlet 212 to the inner container 10 can shorten the delivery path of the electrolyzed disinfectant water, reduce the stagnation loss of the water flow in the pipeline, and ensure that the high-concentration disinfectant water can quickly enter the washing space, thereby improving the disinfection efficiency of the tableware.

[0069] Further, in an alternative embodiment, the electrolysis water tank 21 is detachably connected to the side wall 11 of the inner container 10. For the detachable connection, a screw hole can be used for fixation, a buckle and a slot can be used for fixation, or magnetic pieces can be used for fixation.

[0070] The detachable connection is described below. For example, a fixed plate can be additionally arranged on both sides of the electrolysis water tank 21, and the number of fixed plates can be changed by those skilled in the art according to actual conditions, such as one, two, three, four, etc. Screw holes are then formed in the fixed plates, and screw hole slots are formed in the inner container 10 at positions corresponding to the screw holes. Then, the screws are sequentially inserted through the screw holes in the fixed plates and the screw hole slots in the inner container 10, thereby connecting the electrolysis water tank 21 to the inner container 10. Further, when the buckle and the slot are used for fixation, buckles can be additionally arranged on the electrolysis water tank 21, and the number of buckles can be changed by those skilled in the art according to actual conditions, such as one, two, three, four, etc. Slots that can cooperate with the buckles are then formed in the inner container 10 at positions corresponding to the buckles. Then, the buckles on the electrolysis water tank 21 are directly inserted into the slots in the inner container 10, thereby connecting the electrolysis water tank 21 to the inner container 10. When the magnetic pieces are used for fixation, magnetic pieces can be additionally arranged on the electrolysis water tank 21, and the number of magnetic pieces can be changed by those skilled in the art according to actual conditions, such as one, two, three, four, etc. Then, opposite magnetic pieces that can attract the magnetic pieces are formed in the inner container 10 at positions corresponding to the magnetic pieces. Then, the magnetic pieces on the electrolysis water tank 21 are directly aligned and inserted into the opposite magnetic pieces in the inner container 10, thereby magnetically connecting the electrolysis water tank 21 to the inner container 10.

[0071] Of course, the embodiment only exemplifies the detachable connection, but is not limited thereto, and those skilled in the art can make changes according to actual conditions, as long as the same technical effects can be achieved.

[0072] In this way, the electrolytic water tank 21 is detachably connected to the side wall 11 of the inner container 10, without welding, and can be fixed to the side wall 11 of the inner container 10 by buckling, screws or the like, so that the assembly process can be reduced and the assembly efficiency can be improved. In addition, during maintenance, the water tank can be removed by only disassembling the connecting member without disassembling the whole machine or damaging the structure, so that the maintenance time and cost can be reduced whether the water tank is replaced due to failure or the electrode assembly 22 is maintained. At the same time, if the merchant subsequently launches an electrolytic water tank 21 with better performance, the user can upgrade without replacing the whole machine, thereby prolonging the life cycle of the dishwasher and improving the cost performance of the product.

[0073] Further, in an optional embodiment, the electrolytic water tank 21 is provided with a mounting opening, one end of the electrode assembly 22 extends into the electrolytic water tank 21 through the mounting opening, and the other end of the electrode assembly 22 is provided with a cover 23 adapted to close the mounting opening.

[0074] Of course, in order to ensure the sealing, a sealing strip can be installed on the outer edge of the cover 23 and the inner edge of the mounting opening, and when the electrode assembly 22 is completely inserted into the electrolytic water tank 21, the cover 23 can cover the mounting opening, and the sealing strip between the two can achieve the sealing effect. However, the sealing strip can further fasten the cover 23 and the mounting opening to prevent them from being separated.

[0075] In this way, the electrode assembly 22 is mounted into the electrolytic water tank 21 through the mounting opening, and the cover 23 can close the mounting opening. During assembly, the electrode assembly 22 can be directly inserted into the electrolytic water tank 21 to complete the installation, which can obviously reduce the installation steps compared with the traditional installation in the electrolytic water tank 21. In addition, the mounting opening can provide a precise positioning reference for the electrode assembly 22, and the electrode can be guided into place along the mounting opening when it is inserted, avoiding the deviation in the traditional assembly and improving the electrolytic stability. Further, during maintenance, the electrode assembly 22 can be taken out from the mounting opening by only opening the cover 23, without disassembling the water tank, so that the electrode can be quickly taken out for deep cleaning or replacement, greatly simplifying the electrode cleaning and replacement process.

[0076] Further, in an optional embodiment, the electrode assembly 22 includes an electrode group 221 and a mounting seat 222.

[0077] Specifically, in this embodiment, the electrode group 221 is composed of at least one electrode sheet 2211, for example, one, two, three, four, five or the like, of course, this embodiment only exemplifies the number of electrode sheets 2211, but is not limited thereto, and those skilled in the art can make changes according to the actual situation, as long as the same technical effects can be achieved.

[0078] Further, in the embodiment, the mounting base 222 is provided with a cover 23, and the mounting base 222 is provided with fixing grooves 2221 on the side away from the cover 23, and the number of the fixing grooves 2221 corresponds to the number of the electrode sheets 2211. One end of each electrode sheet 2211 is embedded into the corresponding fixing groove 2221 to be connected with the mounting base 222, and the other end of each electrode sheet 2211 is adapted to extend into the electrolytic water tank 21.

[0079] For the connection mode of the electrode sheet 2211 and the fixing groove 2221, the embedded interference fit mode can be directly used for connection, or the adhesive or welding mode can be used for fixation after embedding. Of course, the embodiment only exemplarily illustrates the fixation mode of the electrode sheet 2211 and the mounting base 222, but is not limited thereto, and those skilled in the art can change it according to the actual situation, as long as the same technical effect can be achieved.

[0080] In this way, in the conventional electrode assembly 22, the electrode sheets 2211 are usually fixed in a scattered manner, such as being directly welded to the inner wall of the water tank, which makes the spacing between the electrode sheets 2211 uneven, and the electrode sheets 2211 are easily shaken by the water flow during the electrolysis process, resulting in uneven discharge and low efficiency during electrolysis. The embodiment makes the number of the fixing grooves 2221 correspond to the number of the electrode sheets 2211, so that each electrode sheet 2211 can be embedded in the exclusive fixing groove 2221, and the spacing can be strictly controlled through the preset size of the fixing groove 2221, to ensure uniform discharge of the electrode group 221 and improve the efficiency of the disinfectant water preparation. Further, the mounting base 222 provides a unified support carrier for the electrode group 221, and the electrode sheet 2211 is firmly connected with the mounting base 222 through the fixing groove 2221, to avoid shaking and displacement of the electrode sheet 2211 and reduce the risk of short circuit. Further, since the mounting base 222 is integrated with the cover 23, the electrode assembly 22 can be connected with the water tank through the mounting base 222 as a whole, without the need to separately fix each electrode sheet 2211, which simplifies the assembly process of the electrode and the water tank and improves the production efficiency.

[0081] Further, in an alternative embodiment, the electrode assembly 22 further comprises a connecting sheet 223 connected with the mounting base 222. The connecting sheet 223 is provided with connecting grooves on the side close to the electrode group 221, and the number of the connecting grooves corresponds to the number of the electrode sheets 2211. Each electrode sheet 2211 is provided with a notch matched with the connecting groove, and each electrode sheet 2211 is clamped into the corresponding connecting groove through the notch, so that each electrode sheet 2211 is connected with the connecting sheet 223.

[0082] That is, the connecting piece 223 is used to fix all the electrode pieces 2211, and then the connecting piece 223 is connected with the mounting base 222, and all the electrode pieces 2211 are connected with the mounting base 222, to realize secondary fixation.

[0083] For the connecting mode of the connecting piece 223 and the mounting base 222, the screw hole screwing mode can be used for fixation, the buckle and slot mode can be used for fixation, and the magnetic piece attraction mode can be used for fixation. Of course, the embodiment only exemplarily illustrates the connecting mode of the connecting piece 223 and the mounting base 222, but does not limit this, and the person skilled in the art can change according to the actual situation, as long as the same technical effect can be realized.

[0084] In this way, the connecting piece 223 in the embodiment is clamped with all the electrode pieces 2211 through the connecting slot, and an integrated electrode unit can be formed, and the assembly process can be simplified. Moreover, the cooperation of the connecting slot and the notch further strengthens the positioning of the electrode pieces 2211, and on the basis of the fixing slot 2221, the connecting slot forms a constraint from the other side of the electrode piece 2211, to prevent the electrode piece 2211 from moving in the up-down and front-back directions, and the double positioning ensures the long-term stability of the electrode spacing, avoiding the fluctuation of the electrolysis efficiency due to the change of the spacing. Further, the clamping structure is more easily disassembled than welding, and if a single electrode piece 2211 is damaged, it can be directly taken out and replaced from the connecting slot without damaging the connecting piece 223 or other electrode pieces 2211, reducing the maintenance cost.

[0085] Further, in an alternative embodiment, the electrode assembly 22 further comprises a limiting piece, and the limiting piece is arranged on the outer periphery of the electrode group 221. Under the action of an external force, the limiting piece has a first position of buckling to the outer periphery of the electrode group 221 and fixing all the electrode pieces 2211, and a second position of being separated from the outer periphery of the electrode group 221.

[0086] The limiting piece can be a buckling clamp, a buckling rib, or a fastening strip. When fixing the electrode pieces 2211, the limiting piece is directly moved to the outer periphery of the electrode group 221, and then the buckling clamp, the buckling rib, or the fastening strip is directly used to fasten the electrode group 221 as a whole.

[0087] Of course, the buckles and slots matched at the two ends of the limiting piece can also be directly arranged, and the overall length of the limiting piece is matched with the outer periphery circumference of the electrode group 221, so that the buckles and slots arranged at the two ends of the limiting piece are directly buckled when fastening.

[0088] When disassembly is needed, the limiting piece is directly operated in reverse to be disengaged.

[0089] In this embodiment, when the limiting member is in the first position, it is buckled around the outer periphery of the electrode group 221 to form a ring-shaped constraint, which can prevent the electrode sheet 2211 from expanding outward and deforming, and ensure that the electrode gap always meets the design requirements, thereby avoiding the problem of reduced electrolysis efficiency caused by increased gap. In addition, the limiting member can resist the impact of water flow on the outer periphery of the electrode sheet 2211, reduce the shaking of the electrode sheet 2211, and reduce the risk of short circuit. Further, since the limiting member can be detached from the electrode group 221 in the second position, it will not affect the disassembly of the electrode assembly 22, and the electrode sheet 2211 can be removed by switching to the second position during maintenance, which is flexible and avoids the problem of difficult disassembly of the traditional fixed limiting structure.

[0090] Further, in an alternative embodiment, the limiting member includes at least one pair of limiting racks 224, which are respectively arranged on both sides of the electrode group 221. Under the action of external force, the two limiting racks 224 have a first position in which they are buckled to the outer periphery of the electrode group 221 and fix all the electrode sheets 2211, and a second position in which they are detached from the outer periphery of the electrode group 221.

[0091] That is, the two limiting racks 224 are respectively arranged on both sides of the electrode group 221, for example, they can be arranged on the front and rear sides of the electrode group 221, so that the buckling portions of the two limiting racks 224 are located on the left and right sides of the electrode group 221. Or the two limiting racks 224 are arranged on the left and right sides of the electrode group 221, so that the buckling portions of the two limiting racks 224 are located on the front and rear sides of the electrode group 221.

[0092] Of course, the present embodiment only exemplifies the arrangement of the two limiting racks 224, but does not limit it, and those skilled in the art can change it according to the actual situation as long as the same technical effect can be achieved.

[0093] In this embodiment, the limiting rack 224 is buckled from both sides of the electrode group 221, rather than being integrally sleeved, so it does not need to slide axially during disassembly, especially in the case of a small internal space in the water tank, it only needs to separate the limiting rack 224 to the two sides to complete the detachment, which requires small operation space and is suitable for the compact environment of a flat water tank. In addition, compared with unilateral limiting, symmetrical buckling on both sides can form balanced fixing force, and the two limiting racks 224 can simultaneously apply constraints from the front and rear directions of the electrode group 221, thereby avoiding the unilateral deviation of the electrode sheet 2211 and further improving the stability of the electrode gap. Further, since multiple pairs of limiting racks 224 are provided, if one of the limiting racks 224 is damaged, only a single component needs to be replaced, without the need for overall replacement, thereby reducing maintenance costs.

[0094] Further, in an optional embodiment, the limiting frame 224 is provided with a groove 2241, and the electrode sheet 2211 is provided with a notch 2212, which is arranged corresponding to the groove 2241. In the first position, the electrode sheet 2211 is embedded in the groove 2241 through the notch 2212.

[0095] In this way, in the present embodiment, the notch 2212 of each electrode sheet 2211 corresponds to the groove 2241 of the limiting frame 224, and after embedding, the displacement of the electrode sheet 2211 itself can be limited, so that accurate positioning of the limiting frame 224 and the electrode sheet 2211 is achieved. Moreover, the structure of the notch 2212 embedded in the groove 2241 can further limit the displacement of the electrode sheet 2211. In addition to the constraint of the outer periphery of the limiting frame 224, the groove 2241 can also clamp the electrode sheet 2211 from various directions, preventing the electrode sheet 2211 from shaking in a direction perpendicular to the clamping direction of the limiting frame 224, forming a multi-dimensional fixation, which is particularly suitable for scenarios where the water flow direction is complex during electrolysis. Further, the cooperation of the groove 2241 and the notch 2212 can also simplify the assembly process. During assembly, the electrode sheet 2211 can be quickly positioned through the notch 2212 and the groove 2241, without the need to repeatedly adjust the position of the limiting frame 224, thereby improving assembly efficiency.

[0096] Further, in an optional embodiment, each pair of limiting frames 224 is connected to each other when clamped to the outer periphery of the electrode group 221, and each pair of limiting frames 224 is disconnected from each other after being separated.

[0097] In this way, in the present embodiment, the pair of limiting frames 224 can form an overall constraint frame after being connected, which can resist greater water flow impact or vibration, avoid unilateral loosening, and ensure the continuous constraint of the electrode group 221. Moreover, since the limiting frame 224 can directly constrain the overall outer periphery of the electrode group 221 when clamped, it can prevent individual electrode sheets 2211 from being displaced due to vibration or water flow impact. Further, during maintenance, only the connection between the limiting frames 224 needs to be released, such as unfastening the buckle or screw, so that the two limiting frames 224 can be removed respectively without affecting the removal of the electrode sheet 2211, thereby avoiding difficult disassembly and improving maintenance efficiency.

[0098] Further, in an optional embodiment, along the extension direction of the electrode group 221, multiple pairs of limiting frames 224 are uniformly arranged on the electrode group 221.

[0099] In this way, in this embodiment, the plurality of pairs of limiting frames 224 uniformly distributed can divide the electrode group 221 with a relatively long length into a plurality of short segments, so that each segment is constrained, thereby avoiding the middle region of the electrode group 221 from sagging and deforming, so that the deformation of the entire electrode group 221 can be avoided, and the uniform spacing of all electrode sheets 2211 can be ensured. Moreover, segmental fixation can disperse the force, and the force generated by water flow impact or vibration can be borne by the plurality of pairs of limiting frames 224, thereby avoiding damage caused by excessive force on a single pair of limiting frames 224, and prolonging the service life of the limiting frames 224. Further, the uniform distribution of the plurality of pairs of limiting frames 224 can also improve the fatigue resistance of the electrode group 221. In a long-term electrolysis process, the slight vibration of the electrode sheets 2211 will accumulate fatigue, and the plurality of pairs of limiting frames 224 can reduce the vibration amplitude of each electrode sheet 2211 and reduce the risk of fatigue deformation.

[0100] Further, in an optional embodiment, the electrode assembly 22 is provided with a first electric connection end and a second electric connection end, and the first electric connection end and the second electric connection end are connected with a power supply end of the dishwasher. The polarity of the first electric connection end and the second electric connection end is reversed every predetermined time length. For example, the polarity of the first electric connection end and the second electric connection end can be reversed every 0.01s to 100s.

[0101] For the reversing mode, the current direction of the power supply end can be changed, so that the polarity of the first electric connection end and the second electric connection end can be reversed.

[0102] In this way, in this embodiment, the polarity of the electrode assembly 22 can be reversed every time length, and when the current polarity is reversed, the original anode becomes a cathode, and the original cathode becomes an anode, so that the scale on the surface of the anode can be dissolved due to oxidation reaction, and the scale on the surface of the cathode can be removed due to reduction reaction, realizing automatic descaling without manual disassembly and cleaning.

[0103] Further, in an optional embodiment, the inside of the electrolytic water tank 21 is provided with a first overflow port 213 and a breather, and the breather is provided with a second overflow port 214. One end of the second overflow port 214 communicates with the first overflow port 213 through an overflow pipeline 215, and the other end of the second overflow port 214 communicates with the inner container 10.

[0104] In this way, in this embodiment, by providing the first overflow port 213 and the second overflow port 214, when the water inflow is abnormally excessive, the water first enters the overflow pipeline 215 through the first overflow port 213, and then flows into the inner container 10 through the second overflow port 214, so that the water can be prevented from leaking out of the electrolytic water tank 21, damaging the circuit, side plate and other components inside the machine body, and at the same time, the overflow water is recycled to the inner container 10 to participate in the subsequent washing and disinfection process, realizing water resource recycling and solving the problem of waste caused by traditional overflow drainage.

[0105] While embodiments of the present application have been described in connection with the preferred embodiments of the various figures, those of ordinary skill in the art will appreciate that various modifications and variations of the preferred embodiments can be employed without departing from the spirit and scope of the application.
