Abstract

The present invention relates to a cleaning device with a disinfection function, comprising a shell and a disinfectant water generating device, wherein the disinfectant water generating device comprises: a water storage structure; a discharge electrode, arranged in the water storage structure; an electrode fixing frame, arranged on the water storage structure; an insulating tube, the upper end of which is fixedly connected to the electrode fixing frame, the discharge electrode being located in the insulating tube, a first air guide section being formed on the electrode fixing frame, a second air guide section being formed in the insulating tube, a bell mouth being formed at one end of the insulating tube connected to the electrode fixing frame, the inner peripheral wall of the bell mouth being arranged to expand in diameter from bottom to top; a first sealing structure being arranged between the insulating tube and the electrode fixing frame; and a ground electrode, which is arranged in the water storage structure. When water vapor generated during the discharge process of the discharge electrode gathers and condenses into water droplets at the top of the insulating tube, the bell mouth can guide the water droplets to flow down quickly, thereby avoiding water accumulation at the first sealing ring, which would cause the discharge of the discharge electrode to penetrate the first sealing ring along the accumulated water and affect the seal.

[0001] The present invention relates to the technical field of disinfection and sterilization equipment, and in particular to a cleaning equipment with a disinfection function. Background Art

[0002] This section merely provides background information related to the present disclosure and is not necessarily prior art.

[0004] The applicant has developed a cleaning device with a disinfecting function that uses electrodes to electrolyze a specific medium to produce ion clusters or ion solutions with a disinfecting effect. However, the water vapor generated during the discharge process of the discharge electrode in this cleaning device tends to accumulate as water droplets on the top of the insulating tube. This can cause the discharge of the discharge electrode to penetrate the first sealing ring along the accumulated water, causing damage to the first sealing ring and affecting the seal. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that the discharge of the discharge electrode of the cleaning equipment with a disinfection function is easy to break through the sealing ring along the accumulated water, thereby providing a cleaning equipment with a disinfection function, in which the water vapor generated by the discharge of the discharge electrode is not easy to gather at the top of the insulating tube, which can reduce the risk of the discharge electrode breaking through the sealing ring along the accumulated water, and ensure that the cleaning equipment can operate stably.

[0006] In order to solve the above problems, the present invention provides a cleaning device with a disinfection function, comprising: a shell; a disinfectant water generating device, which is arranged in the shell, and the disinfectant water generating device includes: a water storage structure; a discharge electrode, which is arranged in the water storage structure and is suitable for being connected to the live wire of a power supply device; an electrode fixing frame, which is arranged on the water storage structure, and the discharge electrode is fixedly arranged on the electrode fixing frame; an insulating tube, the upper end of which is fixedly connected to the electrode fixing frame, and the discharge electrode is located in the insulating tube, a first air guide section suitable for allowing air to pass is formed on the electrode fixing frame, a second air guide section connected to the first air guide section is formed in the insulating tube, a bell mouth is formed at one end of the insulating tube connected to the electrode fixing frame, and the inner peripheral wall of the bell mouth is expanded from bottom to top; a first sealing structure, which is arranged between the insulating tube and the electrode fixing frame, and is suitable for sealing the gap between the electrode fixing frame and the insulating tube; a ground electrode, which is arranged in the water storage structure and is suitable for being connected to the neutral wire of the power supply device.

[0007] Furthermore, an annular groove is formed on the electrode fixing frame, and the top of the bell mouth is embedded in the annular groove.

[0008] Furthermore, the gas outlet end of the first gas guiding section is higher than the annular groove.

[0009] Furthermore, a first circumferential flange is formed on the peripheral wall of the insulating tube, and the first sealing structure is a first sealing ring sleeved outside the insulating tube.

[0010] Furthermore, a limiting ring groove surrounding the gas outlet end of the insulating tube is formed on the electrode fixing frame, and the first sealing structure is arranged in the limiting ring groove.

[0011] Furthermore, the disinfectant water generating device also includes a porous structure, which is arranged in the water storage structure and sealedly connected to the air outlet end of the insulating tube.

[0012] Furthermore, the disinfectant water generating device also includes a second sealing structure arranged between the insulating tube and the porous structure and suitable for sealing the gap between the insulating tube and the porous structure.

[0013] Furthermore, a second circumferential flange is formed on the outer peripheral wall of the insulating tube, and the second sealing structure is a second sealing ring sleeved outside the insulating tube.

[0014] Furthermore, the air inlet end and the air outlet end of the insulating tube are symmetrically arranged.

[0015] Furthermore, the cleaning device with a disinfection function is a dishwasher.

[0016] The present invention has the following advantages:

[0017] In the cleaning equipment with a disinfection function provided by the present invention, a bell mouth is formed at one end where the insulating tube is connected to the electrode fixing frame, and the inner peripheral wall of the bell mouth is set to expand from bottom to top. This allows the water vapor generated during the discharge process of the discharge electrode to gather and condense into water droplets at the top of the insulating tube, and the bell mouth can guide the water droplets to flow down quickly, avoiding the accumulation of water at the first sealing ring. As a result, after the accumulated water contacts the first sealing ring, the discharge electrode will work and discharge along the accumulated water to penetrate the first sealing ring, causing damage to the first sealing ring and affecting the seal. Therefore, the cleaning equipment with a disinfection function of the present invention can overcome the defect of the cleaning equipment in the prior art that the discharge electrode can easily penetrate the sealing ring along the accumulated water during the work of the discharge electrode, and can improve the safety of the cleaning equipment and ensure that the cleaning equipment can operate stably.

[0034] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0035] Example 1

[0036] Figure 1 A perspective view of a disinfectant water generating device according to embodiment 1 of the present invention is shown. Figure 2 This is a top view of the disinfectant water generating device of Example 1 of the present invention. Figure 3 like Figure 2 The cross-sectional view of the disinfectant water generating device along line AA is shown. Figure 1 、 Figure 2 and Figure 3 As shown, Example 1 relates to a cleaning device with a disinfection function, comprising a housing and a disinfectant water generator a. Disinfectant water generator a is disposed within the housing and includes a water storage structure a1, a discharge electrode a21, an electrode holder a5, an insulating tube a6, a first sealing structure, and a ground electrode a22. The discharge electrode a21 is disposed within the water storage structure a1 and is adapted to connect to the live wire of a power supply. The electrode holder a5 is disposed on the water storage structure a1, and the discharge electrode a21 is fixedly mounted on the electrode holder a5.

[0037] The upper end of the insulating tube a6 is fixedly connected to the electrode holder a5. The discharge electrode a21 is located within the insulating tube a6. The electrode holder a5 is formed with a first air guide section a52 suitable for admitting air. A second air guide section a61 is formed within the insulating tube a6 and is connected to the first air guide section a52. The end of the insulating tube a6 connected to the electrode holder a5 is formed with a bell mouth a64 (see FIG. Figure 4 The inner circumferential wall of the bell mouth a64 is configured to expand in diameter from bottom to top. A first sealing structure is provided between the insulating tube and the electrode holder a5, adapted to seal the gap between the electrode holder a5 and the insulating tube a6. A ground electrode a22 is provided within the water storage structure a1 and adapted to be connected to the neutral line of the power supply.

[0038] The applicant found that the bactericidal components such as single oxygen atoms, ozone ion groups, hydrogen peroxide ion groups, hydroxyl groups, and nitroso groups produced by the current disinfectant water generating device have limited contact area with water, and the bactericidal components cannot be fully dissolved in water, resulting in a low concentration of the generated disinfectant water and poor disinfection and sterilization effect on tableware.

[0039] The applicant has designed a disinfectant water generator, comprising a water storage structure having an air inlet and an air outlet, an electrode mounting bracket mounted on the water storage structure, an insulating tube mounted within the water storage structure, a discharge electrode mounted within an air inlet passage, a sealing structure adapted to seal the gap between the motor mounting bracket and the insulating tube, and an air inlet passage formed within the electrode mounting bracket and the insulating tube and surrounding the discharge electrode. The disinfectant water generated by this disinfectant water generator has a good disinfecting and sterilizing effect. However, the applicant has discovered that during use, there is a risk of the sealing structure being punctured, hindering the stable and reliable operation of the disinfectant water generator.

[0040] As can be seen from the above technical solution, when the disinfecting cleaning device of Example 1 needs to prepare disinfectant water, the power supply device provides a high-frequency alternating voltage of approximately 10kV-12kV to the disinfectant water generating device a. Air enters the water storage structure a1 through the insulating tube a6, and the discharge electrode a21 generates a discharge arc phenomenon, thereby electrolyzing the air in the insulating tube a6 to produce single oxygen atoms, ozone ion groups, hydrogen peroxide ion groups, hydroxyl groups, nitroso groups, and other bactericidal components. Ozone and other bactericidal components can be injected into the water through the air outlet of the insulating tube a6. Therefore, the insulating tube a6 can act as an aerator, increasing the contact area between ozone and other bactericidal components and water, thereby allowing ozone and other bactericidal components to be more fully dissolved in the water, thereby increasing the solubility of the bactericidal components, resulting in a higher concentration in the prepared disinfectant water, having a better disinfection and sterilization effect, and reducing the risk of ozone not dissolving in the water and being discharged to pollute the air or produce odor.

[0041] The nitrogen oxides produced by the electrolysis of air can generate highly oxidizing nitric acid and nitrous acid after dissolving in water. The water vapor carried in the air can generate hydroxyl radicals after being electrolyzed. The hydroxyl radicals can generate highly oxidizing hydrogen peroxide after dissolving in water, thereby further enhancing the disinfection and sterilization effect of the disinfectant water.

[0042] In addition, because the end of the insulating tube a6 connected to the electrode fixing frame a5 is formed with a bell mouth a64, and the inner peripheral wall of the bell mouth a64 is arranged to expand in diameter from bottom to top, when water vapor generated during the discharge process of the discharge electrode a21 gathers and condenses into water droplets at the top of the insulating tube a6, the bell mouth a64 can guide the water droplets to flow down quickly, thereby preventing water from accumulating at the first sealing ring. If the accumulated water contacts the first sealing structure, the discharge of the discharge electrode a21 during operation will break through the first sealing ring along the accumulated water, causing damage to the first sealing structure and affecting the seal.

[0043] In this embodiment, an annular groove a53 is preferably formed on the electrode fixing frame a5. The top of the bell mouth a64 is embedded in the annular groove a53. The annular groove a53 can limit the upper end of the insulating tube a6, thereby effectively ensuring that the air inlet channel is not prone to shaking during the movement of the disinfectant water generating device a, ensuring that the spacing between the discharge electrode a21 and the air inlet channel is uniform, and avoiding the reduction of the creepage distance due to the distance between one side of the discharge electrode a21 and the first sealing structure being too close, causing the first sealing structure to be punctured. Preferably, the inner wall of the annular groove a53 is configured to be suitable for matching the bell mouth a64 that accommodates the insulating tube a6, which can guide the installation of the insulating tube a6 and increase the contact area between the annular groove a53 and the bell mouth a64, further reducing the risk of the insulating tube a6 being damaged by the electrode fixing frame a5.

[0044] In this embodiment, if Figure 6 and Figure 7 As shown, the air outlet end of the first air guide section a52 is higher than the annular groove a53. This can prevent the upper end of the insulating tube a6 from blocking the air outlet end of the first air guide section a52 when the upper end of the insulating tube a6 is inserted into the first air guide section a52.

[0045] The first sealing structure can be optionally a sealing gasket, which is formed with a first avoidance hole. The edge of the first avoidance hole extends into the first air guide section a52 and abuts against the upper end of the insulating tube a6. Preferably, in this embodiment, a first circumferential flange a62 is formed on the peripheral wall of the insulating tube a6. The first sealing structure is a first sealing ring a422 that is sleeved outside the insulating tube a6. The first sealing ring a422 can not only prevent rigid contact between the insulating tube a6 and the electrode fixing frame a5, but also avoid air leakage between the insulating tube a6 and the electrode fixing frame a5, and increase the distance between the first sealing structure and the port of the insulating tube a6, effectively extending the creepage distance. The first sealing ring a422 is not easily punctured, which is conducive to the stable and reliable operation of the disinfectant water generating device a.

[0046] In this embodiment, the electrode holder a5 is formed with a retaining ring groove surrounding the outlet end of the insulating tube a6. The first sealing structure is disposed within the retaining ring groove. The retaining ring groove serves to position the first sealing structure, facilitating its installation and preventing displacement that could compromise the seal between the insulating tube a6 and the electrode holder a5.

[0047] In this embodiment, the disinfectant water generating device a further comprises a porous structure disposed within the water storage structure a1 and sealedly connected to the air outlet end of the insulating tube a6. Ozone and other bactericidal components generated by electrolysis can be discharged into the porous structure through the air outlet end of the air inlet channel. The porous structure can disperse the ozone from the air inlet channel into uniform, fine bubbles and release them into the water, thereby effectively increasing the contact area between the ozone and other bactericidal components and the water, increasing their solubility, and resulting in a higher concentration in the prepared disinfectant water, achieving a better disinfection and sterilization effect. It also reduces the risk of ozone not dissolving in the water, leading to ozone emissions that pollute the air or produce odors.

[0048] In addition, the nitrogen oxides produced by electrolysis of air can generate strong oxidizing nitric acid and nitrous acid after dissolving in water. The water vapor carried in the air can generate hydroxyl radicals after being electrolyzed, and the hydroxyl radicals can generate strong oxidizing hydrogen peroxide after dissolving in water, thereby further improving the disinfection and sterilization effect of the disinfectant. In this embodiment, Figure 5 As shown, the porous structure can be selected as air stone a3. The air outlet end of the air inlet channel is sealed with the air stone a3. The ozone released from the air outlet end of the air inlet channel can be dispersedly released into the water by the air stone a3.

[0049] The air outlet end of the air inlet channel can be optionally bonded or abutted with the bubble stone a3, or an abutting protrusion suitable for inserting into the air inlet channel and sealing the air inlet channel is formed on the bubble stone a3. Preferably, in this embodiment, a fixing hole suitable for fixing the air inlet channel is formed on the bubble stone a3. The air outlet end of the air inlet channel extends into the fixing hole. The fixing hole can not only limit the air outlet end of the air inlet channel, but also increase the contact area between the air inlet channel and the bubble stone a3, which helps to improve the air tightness between the air inlet channel and the bubble stone a3. And compared to making the inner wall of the air inlet channel contact with the bubble stone a3, when the outer peripheral wall of the air inlet channel contacts with the bubble stone a3, the outer peripheral wall of the air inlet channel is not easily compressed by the bubble stone a3 and damaged.

[0050] In such Figure 8 、 9 In the embodiment shown in Figure 10, the porous structure includes an air chamber a81 and a waterproof breathable membrane a84. A first opening a82 and a second opening a83 are formed in the air chamber a81, and the outlet end of the air inlet channel is sealed with the first opening a82 of the air chamber a81. The waterproof breathable membrane a84 blocks the second opening a83. Ozone released from the outlet end of the air inlet channel can be passed into the air chamber a81. The waterproof breathable membrane a84 allows ozone to pass through and be dispersedly released into the water, while preventing water in the water storage structure a1 from entering the air chamber a81. The water-facing surface of the waterproof breathable membrane a84 is PTFE, and the water-repellent surface is PP&PE.

[0051] In this embodiment, the disinfectant water generating device a also includes a second sealing structure arranged between the insulating tube a6 and the porous structure and suitable for blocking the gap between the insulating tube a6 and the porous structure. The second sealing structure is suitable for blocking the gap between the insulating tube a6 and the porous structure. The second sealing structure is suitable for blocking the gap between the insulating tube a6 and the porous structure. The second sealing structure can avoid air leakage between the insulating tube a6 and the porous structure, ensuring that the ozone and other bactericidal components generated by electrolysis can be dispersedly released into the water by the porous structure, thereby further improving the solubility of bactericidal components such as ozone. The second sealing structure can also replace the porous structure to make flexible contact with the insulating tube a6, thereby reducing the risk of the insulating tube a6 being damaged by the porous structure. The second sealing structure is preferably, but not limited to, made of a flexible material such as rubber or silicone.

[0052] The second sealing structure can optionally be formed with a second escape hole that allows the discharge electrode a21 to pass through. The edge of the second escape hole abuts the lower end of the insulating tube a6, and the outlet end of the insulating tube a6 abuts the second sealing structure. Ozone and other sterilizing agents released from the outlet end of the insulating tube a6 can pass through the second escape hole into the porous structure and be dispersed into the water.

[0053] Preferably, in this embodiment, a second circumferential flange a63 is formed on the circumferential wall of the insulating tube a6. The second sealing structure is a second sealing ring a412 that is sleeved over the insulating tube a6. By positioning the second sealing ring a412 between the second circumferential flange a63 and the porous structure and passing the insulating tube a6 through the second sealing ring a412, not only can rigid contact between the insulating tube a6 and the porous structure be prevented, thereby preventing air leakage between the insulating tube a6 and the porous structure, but the distance between the second sealing structure and the end of the insulating tube a6 can also be increased, effectively extending the creepage distance. This makes the second sealing structure less susceptible to breakdown, thereby facilitating the stable and reliable operation of the disinfectant water generating device a.

[0054] In this embodiment, the air inlet end and the air outlet end of the insulating tube a6 are symmetrically arranged, which allows the operator to assemble the insulating tube a6 without confirming the front and back of the insulating tube a6, avoiding the insulating tube a6 being installed upside down and affecting the air tightness of the disinfectant water generating device a, and helps to improve the operator's assembly efficiency.

[0055] The cleaning device with a disinfection function is preferably, but not limited to, a washing machine, a dishwasher, or a floor scrubber with a disinfection function. For example, in this embodiment, the cleaning device with a disinfection function is a dishwasher.

[0056] 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 readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
