[0002] With the improvement of living standards, dishwashers have gradually entered ordinary households, freeing up hands and improving the quality of life. Generally, the main core components of existing dishwashers include: inner tank assembly, water cup assembly, spray arm assembly, filter assembly, wash pump, drain pump, pipeline, etc.

[0003] Currently, there are dishwasher products in the existing technology that can use electrolytic reactions to generate specific ion group products, thereby making the washing water have a disinfecting effect. However, the above-mentioned products require discharge during the electrolysis process. However, the electric shock of the discharge can easily damage the electrolytic components and other parts, affecting the safety and stability of the product. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the problem that the discharge phenomenon that occurs when the dishwasher produces disinfection products through electrolytic reaction in the prior art easily causes electric shock to damage structural components, affecting the safety and stability of the product.

[0005] The present invention provides a disinfectant water generating device, comprising: an insulating tube, a discharge electrode is provided in the inner cavity of the insulating tube, and a ground electrode is provided on the outside of the insulating tube, the insulating tube and the discharge electrode are spaced apart, and the inner cavity of the insulating tube is connected to an air inlet port and an exhaust port; an electrode fixing frame is provided on the top side of the insulating tube and is respectively connected to the insulating tube and the discharge electrode; a drainage structure is provided on the insulating tube and is connected to the insulating tube, and is suitable for leading out and condensing the steam inside the insulating tube and discharging condensed water.

[0006] The drainage structure includes: a water guide part, which is arranged on the circumferential side of the insulating tube and is connected to the inner cavity of the insulating tube; a drainage part, which is arranged on the side of the water guide part away from the insulating tube and is provided with a drainage port connected to the water guide part, and the drainage port is suitable for discharging steam condensate.

[0007] The water guide portion is arranged on the lower side of the air inlet port.

[0008] The water guide portion includes: a guide channel, which is arranged in a ring-shaped and inclined manner along the circumference of the insulating tube, with its lower end communicating with the inner cavity of the insulating tube and its inner diameter being smaller than that of its upper end.

[0009] The drainage part includes: a condensation trough, the opening of which is arranged toward the electrode fixing frame and is arranged around the guide channel. The upper edge of one side is connected to the guide channel, and the drain port is arranged at the bottom of the condensation trough.

[0010] The disinfectant water generating device further includes: a second sealing structure, which is arranged between the insulating tube and the electrode fixing frame and is suitable for sealing the gap between the insulating tube and the electrode fixing frame.

[0011] The drainage structure is arranged at the end of the insulating tube facing the electrode fixing frame.

[0012] An upper edge of the condensation groove, which is away from the guide channel, is in sealing contact with the second sealing structure.

[0013] The drainage structure is integrally formed with the insulating tube.

[0014] The present invention also provides a cleaning device, comprising the above-mentioned disinfectant water generating device.

[0015] The cleaning equipment is a dishwasher.

[0016] The technical solution of the present invention has the following advantages:

[0017] 1. The disinfectant water generating device provided by the present invention includes: an insulating tube, a discharge electrode is provided in the inner cavity of which, and a ground electrode is provided on the outside of which, the insulating tube and the discharge electrode are spaced apart, and the inner cavity of the insulating tube is connected to an air inlet port and an exhaust port; an electrode fixing frame is provided on the top side of the insulating tube, and is respectively connected to the insulating tube and the discharge electrode; a drainage structure is provided on the insulating tube and is connected to the insulating tube, and is suitable for leading out and condensing the steam inside the insulating tube and discharging condensed water.

[0018] Through the insulating tube with the discharge electrode inside and the electrode fixing frame, air is introduced through the air inlet port, which facilitates the discharge of the discharge electrode to electrolyze the air and produce ozone, and then discharge it from the exhaust port. Furthermore, a drainage structure is provided to drain the steam or steam condensate in the insulating tube, avoiding the accumulation of steam condensate in the insulating tube, and thus avoiding damage to the surrounding structure due to conductive breakdown during the discharge process of the discharge electrode. This effectively overcomes the problem in the prior art that when the disinfection medium is generated by discharge in the dishwasher, it is easy to accumulate water due to steam condensation, resulting in electric shock damage to structural components.

[0019] 2. In the disinfectant water generating device provided by the present invention, the water guide portion is arranged on the lower side of the air inlet port.

[0020] Since the steam flows from bottom to top in the insulating tube, at the same time, the air is introduced into the inner cavity of the insulating tube through the air inlet port, flowing from top to bottom. This arrangement allows the steam or steam condensate to flow toward the water guide part under the drive of the external gas, and the steam condensate is not easy to condense on the upper side of the water guide part.

[0021] 3. In the disinfectant water generating device provided by the present invention, the upper edge of the condensation tank on one side away from the guide channel is sealed and abutted against the second sealing structure.

[0022] The distal upper edge of the condensate trough is arranged to abut against the second sealing structure. This arrangement allows the second sealing structure to be away from the inner cavity of the insulating tube while ensuring the gap between the sealing insulating tube and the electrode fixing frame, further avoiding damage caused by electric shock and affecting the seal.

[0035] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] like Figure 1 - Figure 6 This embodiment provides a disinfectant water generating device, which includes: an insulating tube a6, an electrode fixing frame a5 and a drainage structure b1.

[0037] The insulating tube a6 is provided in a cylindrical shape, specifically, it is made of glass, or it can be a high-temperature resistant plastic tube. A columnar discharge electrode a21 is provided in its inner cavity, and another ground electrode is provided on the outside. The two can be connected to the live wire and the neutral wire of the external power supply device respectively. The insulating tube a6 and the discharge electrode a21 are provided at intervals. The inner cavity of the insulating tube a6 is connected to the air inlet port and the exhaust port a62. In this embodiment, the insulating tube a6 is provided vertically, and the exhaust port a62 is provided at the bottom end of the insulating tube a6 and is connected to the external structure. The external structure is a porous structure, specifically the bubble stone a3. This arrangement is convenient for increasing the contact area between ozone and external water liquid, and is convenient for extracting water droplets from the inner wall of the insulating tube a6, thereby avoiding the accumulation of condensed water on the wall of the insulating tube a6. Furthermore, Figure 1The air inlet port not shown is arranged on the circumference of the groove on the side of the electrode fixing frame a5 facing the insulating tube a6, and the groove is correspondingly arranged in the upward extension direction of the inner cavity of the insulating tube a6. As a convertible embodiment, the air inlet port can also be arranged on the insulating tube a6.

[0038] The electrode fixing frame a5 is arranged on the top side of the insulating tube a6 in the transverse direction and is connected to the insulating tube a6 and the discharge electrode a21 respectively. In this embodiment, Figure 5 As shown in the dotted box, the drainage structure b1 is arranged on the insulating tube a6 and is connected to the inner cavity of the insulating tube a6. It is suitable for draining the steam inside the insulating tube a6, condensing part of the steam into water and discharging it, and discharging part of the steam directly.

[0039] Through the insulating tube a6 with the discharge electrode a21 inside and the electrode fixing frame a5, air is introduced through the air inlet port, which facilitates the discharge of the discharge electrode a21 to electrolyze the air and generate ozone, which is then discharged from the exhaust port a62. Furthermore, a drainage structure b1 is provided to drain the steam or steam condensate in the insulating tube a6, thereby avoiding the accumulation of steam condensate in the insulating tube a6, and thus avoiding damage to the surrounding structure due to conductive breakdown during the discharge process of the discharge electrode a21. This effectively overcomes the problem in the prior art that when a disinfection medium is generated by discharge in a dishwasher, it is easy to accumulate water due to steam condensation, resulting in electric shock damage to structural components.

[0040] In this embodiment, the drainage structure b1 includes a water guide and a drainage section. The water guide is located around the insulating tube a6 and communicates with the inner cavity of the insulating tube a6. The drainage section is located on the side of the water guide away from the insulating tube a6 and can accumulate steam condensate. A drainage port b14 is provided on the water guide, communicating with the water guide, to drain the steam condensate. By providing the water guide and drainage sections separately, steam and accumulated water in the insulating tube a6 can be directed and drained away.

[0041] In this embodiment, the water guide is located below the air inlet port. Since steam flows upward within the insulating tube a6, and air is introduced into the inner cavity of the insulating tube a6 from the air inlet port, flowing downward, this arrangement ensures that steam or condensate, driven by external air, flows toward the water guide, preventing condensate from condensing on the upper side of the water guide.

[0042] Furthermore, the water guide portion includes a flow channel b11, which is arranged in an annular, inclined manner along the circumference of the insulating tube a6. Its lower end communicates with the inner cavity of the insulating tube a6, and its inner diameter is smaller than that of its upper end. The flow channel b11 can be formed independently or by combining it with the electrode holder a5. In this embodiment, the flow channel b11 is formed by combining the flow guide ring wall b12 with the electrode holder a5.

[0043] By setting the guide channel b11 at an angle and with the inner diameter of the lower end smaller than that of the upper end, on the one hand, the inclined guide channel b11 facilitates the inflow of steam airflow from bottom to top after being impacted by external airflow, and on the other hand, water droplets adhering to it can also be left to the exhaust port a62 and discharged.

[0044] The drainage part includes a condensate trough b13, which is arranged in an annular groove and is arranged around the guide channel b11 to facilitate the collection of steam condensate. Its opening is arranged toward the electrode fixing frame a5, that is, the opening is upward to prevent water from spilling. One upper edge of the condensate trough b13 is connected to the guide channel b11. A drain outlet b14 is provided at the bottom of the condensate trough b13 to facilitate the drainage of accumulated water.

[0045] As a convertible embodiment, the bottom of the condensation tank b13 is inclined, and the drain outlet b14 is set at the lowest point of the bottom.

[0046] In this embodiment, the drain structure b1 is positioned at the end of the insulating tube a6 facing the electrode holder a5 and is integrally formed with the insulating tube a6. This facilitates thorough collection of accumulated water, simplifies the structure, and facilitates manufacturing. Alternatively, the drain structure b1 can be positioned in the middle or upper portion of the insulating tube a6, or separately from the insulating tube a6.

[0047] The disinfectant water generator also includes a second sealing structure a42, specifically an elastic rubber sealing ring, disposed between the insulating tube a6 and the electrode holder a5. This seals the gap between the insulating tube a6 and the electrode holder a5 and mitigates impact on the insulating tube a6. Preferably, the condensate tank b13, located on an upper edge away from the diversion channel b11, is in sealing contact with the second sealing structure a42, which is disposed outside the diversion channel b11.

[0048] The distal upper edge of the condensation tank b13 is arranged to abut against the second sealing structure a42. This arrangement allows the second sealing structure a42 to be away from the inner cavity of the insulating tube a6 while ensuring the gap between the sealing insulating tube a6 and the electrode fixing frame a5, further avoiding damage caused by electric shock and affecting the sealing.

[0049] The disinfectant water generating device also includes: a water storage structure a1, a porous structure and an air outlet device, etc.

[0050] The insulating tube a6, electrode holder a5, drainage structure b1, and porous structure are all located within the water storage structure a1. The water storage structure a1 can store water, and its air inlet is connected to the air inlet port. The air outlet of the air outlet device is connected to the air inlet of the water storage structure a1. The porous structure is located below the insulating tube a6 and is submerged in the water. The insulating tube a6 and discharge electrode a21 can be configured as a single or multiple units. Several electrode holders a5 are integrated and arranged at the same height.

[0051] This embodiment also provides a cleaning device, specifically a dishwasher, but may also be a clothing washing and disinfecting machine, etc. The cleaning device includes a shell and a disinfectant water generating device, and the disinfectant water generating device is arranged in the shell.

[0052] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications derived therefrom remain within the scope of protection of the present invention.
