Description

Technical Field

[0001] The present invention relates to the field of sanitary wares, and particularly to an electrolysis device, a method for preparing a disinfectant solution using the same, and an intelligent toilet. Background Art

[0002] Common intelligent toilets in the prior art generally have a disinfection function. Currently, there are mainly three ways to achieve the disinfection function:

[0003] The first is to adopt a physical disinfection method, such as using an ultraviolet lamp for disinfection. This disinfection method is likely to accelerate the aging of toilet components (such as the seat ring), and the exposed ultraviolet rays can cause harm to the human body.

[0004] The second is to add a disinfectant solution to a preset liquid storage container, and the liquid storage container then outputs the disinfectant solution by means of a pump body to disinfect the inner wall surface of the toilet. The following deficiencies exist in this disinfection method: The added disinfectant solution is mainly sodium hypochlorite disinfectant solution, which has the characteristic of being easily decomposed by light, resulting in a reduction in the disinfection activity after the disinfectant solution is added for a period of time.

[0005] The third is to obtain a disinfectant solution by electrolyzing tap water. However, since the disinfection effect is achieved by electrolyzing the chlorine component in tap water, and the chlorine content in tap water is very low, the disinfection effect of the obtained disinfectant solution after electrolysis is not ideal.

[0006] Therefore, the above several disinfection methods for intelligent toilets are not ideal enough and have poor practicability. Summary of the Invention

[0007] The purpose of the present invention is to provide an electrolysis device, a method for preparing a disinfectant solution using the same, and an intelligent toilet to solve the above technical problems existing in the prior art.

[0008] An electrolysis device for a toilet includes an electrolysis body, which is provided with an electrolysis chamber and a liquid outlet. The liquid outlet communicates with the electrolysis chamber, and electrolysis electrodes are installed in the electrolysis chamber; the electrolysis body is further provided with a brine chamber, a water inlet, and a salt addition port. Both the water inlet and the salt addition port communicate with the brine chamber. A drainage member is arranged between the brine chamber and the electrolysis chamber. The brine in the brine chamber is pushed by the water entering the brine chamber towards the drainage member and flows towards the electrolysis chamber through a liquid passing structure provided on the drainage member.

[0009] Further, the drainage member is provided with a water flow groove communicating with the electrolysis chamber. The water flow groove communicates with the liquid passing structure and the water inlet, so that the brine entering the water flow groove is carried away by the water entering the water flow groove and flows into the electrolysis chamber.

[0010] Further, the drainage member is provided with a hollow water guide column. The upper end of the water guide column communicates with the water flow groove, and the lower end of the water guide column extends downward and enters the brine chamber.

[0011] Further, an overflow wall is provided in the water chute. The top end of the overflow wall is lower than the top end of the chute wall of the water chute, and the overflow wall divides the water chute into a first tank body and a second tank body. The first tank body communicates with the water guide column and the water inlet, and the second tank body communicates with the liquid passing structure and the electrolysis chamber.

[0012] Further, the water inlet is located on the side wall of the electrolysis body. The water guiding member is provided with a water inlet column extending downward. The upper end of the water inlet column communicates with the first tank body, and the lower end of the water inlet column communicates with the water inlet.

[0013] Further, it further includes a main control board, which is electrically connected to the electrolysis electrode. When the electrolysis current of the electrolysis electrode is lower than a preset value, the main control board issues an alarm signal. When the electrolysis current of the electrolysis electrode is greater than or equal to the preset value, the main control board controls the electrolysis current of the electrolysis electrode to be a constant value.

[0014] Further, it further includes a liquid extraction pump. The inlet of the liquid extraction pump communicates with the liquid outlet. The main control board is electrically connected to the liquid extraction pump. The main control board judges the liquid level of the electrolysis chamber according to the electrolysis electrode to control the closing time of the liquid extraction pump; a solenoid valve is arranged on the water inlet or the water inlet pipeline connected thereto. The main control board is electrically connected to the solenoid valve. The main control board judges the liquid level of the electrolysis chamber according to the electrolysis electrode to control the opening time of the solenoid valve.

[0015] Further, the liquid passing structure includes one or several liquid passing holes, and the aperture of the liquid passing holes is 1.5 - 3 mm.

[0016] Further, the electrolysis body is provided with a vent for exhaust and / or overflow, and the vent communicates with the electrolysis chamber.

[0017] Further, the electrolysis body includes a box body and an upper cover. The box body is provided with the electrolysis chamber and the brine chamber. The water guiding member is arranged in the box body, and the upper cover is connected to the box body; the salt adding port is arranged on the upper cover, the liquid outlet is arranged on the box body, the water inlet is arranged on the upper cover, or the water inlet is arranged on the box body.

[0018] The present invention further provides a method for manufacturing a disinfectant by an electrolysis device, including the following steps:

[0019] 1) Water enters from the water inlet, and part of the salt added to the brine chamber is dissolved to obtain saturated brine;

[0020] 2) Water enters from the water inlet, the water enters the brine chamber, the saturated brine in the brine chamber is squeezed towards the water guiding member, and is drained to the electrolysis chamber through the water guiding member to add or supplement the electrolyte to the electrolysis chamber;

[0021] 3) When starting electrolysis, the electrolysis electrode in the electrolysis chamber is energized for a preset time to obtain a disinfectant;

[0022] 4) When starting disinfection, drain the disinfectant solution in the electrolysis chamber;

[0023] 5) Repeat steps 2), 3), and 4) until the salt in the brine chamber is exhausted and / or the saturated brine in the brine chamber is used up.

[0024] Further, in step 2), the incoming water is divided into two paths. One path of water flows into the brine chamber, squeezing the saturated brine in the brine chamber towards the drainage member, and the other path of water takes away the saturated brine flowing to the drainage member and flows into the electrolysis chamber.

[0025] Further, in step 5), an alarm signal is issued when the electrolysis current of the electrolysis electrode is lower than a preset value, and when the electrolysis current of the electrolysis electrode is greater than or equal to the preset value, the electrolysis current of the electrolysis electrode is controlled to be a constant value; in step 4), a liquid extraction pump is used to drain the disinfectant solution in the electrolysis chamber, and the liquid level of the electrolysis chamber is judged according to the electrolysis electrode to control the closing time of the liquid extraction pump; a solenoid valve is used to control whether water enters the water inlet. In step 4), the liquid level of the electrolysis chamber is judged according to the electrolysis electrode to control the opening time of the solenoid valve.

[0026] The present invention further provides an intelligent toilet, including the electrolysis device as described in the present invention above. The disinfectant solution electrolyzed in the electrolysis chamber of the electrolysis device is output and sprayed onto the inner wall surface of the toilet through a nozzle.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. Since the electrolysis body of the present invention is also provided with a brine chamber, a water inlet, and a salt addition port, both the water inlet and the salt addition port are communicated with the brine chamber. A drainage member is arranged between the brine chamber and the electrolysis chamber. The brine in the brine chamber is squeezed towards the drainage member by the water entering the brine chamber and flows towards the electrolysis chamber through the liquid passing structure arranged on the drainage member. The present invention uses brine as the electrolyte, with sufficient chlorine components, which can ensure that the disinfection effect of the electrolyzed disinfectant solution is remarkable, and the disinfectant solution can be produced and used immediately, avoiding reducing the disinfection effect. In addition, since the brine in the brine chamber is squeezed towards the drainage member by the water entering the brine chamber and flows towards the electrolysis chamber through the liquid passing structure arranged on the drainage member, the present invention can not only replenish water to the brine chamber, but also automatically continuously replenish the electrolyte to the electrolysis chamber before the salt added in the brine chamber is exhausted, and ensure that the concentration of the electrolyte (i.e., brine) in the electrolysis chamber can always be maintained within a stable range, thereby ensuring the stable disinfection performance of the electrolyzed disinfectant solution.

[0029] 2. The drainage member is provided with a water flow channel communicating with the electrolysis chamber. This water flow channel communicates with the liquid passing structure and the water inlet, so that the brine entering the water flow channel is carried away by the water entering the water flow channel and flows into the electrolysis chamber. In this way, not only can the entry of brine into the electrolysis chamber be accelerated, but also the concentration of brine in the electrolysis chamber can be reduced, ensuring that the concentration of the electrolyte is appropriate.

[0030] 3. The drainage member is provided with a hollow water guiding column. The upper end of the water guiding column communicates with the water flow channel, and the lower end of the water guiding column extends downward into the brine chamber. After water enters the water flow channel, it can be automatically divided into two paths. One path enters the brine chamber through the water guiding column, and the other path is used to carry away the brine entering the water flow channel. The water flow channel and the water guiding column are used for flow splitting, making the structural design simpler, reducing pipeline layout, making the structure more compact and smaller in volume.

[0031] 4. An overflow wall is provided in the water flow channel, dividing the water flow channel into a first tank body and a second tank body. The first tank body communicates with the water guiding column and the water inlet, and the second tank body communicates with the liquid passing structure and the electrolysis chamber, making the effect of flow splitting by the water flow channel and the water guiding column better and avoiding cross-flow.

[0032] 5. The water inlet is located on the side wall of the electrolysis body. The drainage member is provided with a downward-extending water inlet column. The upper end of the water inlet column communicates with the first tank body, and the lower end of the water inlet column communicates with the water inlet, which can avoid the water inlet occupying the space above the electrolysis body.

[0033] 6. The main control board is electrically connected to the electrolysis electrode, and the main control board emits an alarm signal when the electrolysis current of the electrolysis electrode is lower than a preset value. When the electrolysis current of the electrolysis electrode is greater than or equal to the preset value, the main control board controls the electrolysis current of the electrolysis electrode to be a constant value, so that the present invention can not only automatically monitor the usage of sodium chloride (i.e., table salt) and notify the user in time when it is used up, but also ensure that the electrolysis current is constant when the electrolysis electrode is working properly, thereby further ensuring the stable disinfection performance of the disinfectant obtained by electrolysis.

[0034] 7. The main control board is electrically connected to the liquid extraction pump. The main control board judges the liquid level of the electrolysis chamber according to the electrolysis electrode to control the closing time of the liquid extraction pump, so that not only can the disinfectant obtained by electrolysis in the electrolysis chamber be completely pumped out, but also the dry pumping of the liquid extraction pump can be avoided.

[0035] 8. The main control board judges the liquid level of the electrolysis chamber according to the electrolysis electrode to control the opening time of the solenoid valve, ensuring that the electrolysis chamber can be replenished with electrolyte in time, so that there is always electrolyte in the electrolysis chamber that can be electrolyzed when the electrolysis is started next time.

[0036] 9. The liquid passing structure includes one or several liquid passing holes with a pore diameter of 1.5 - 3 mm, which enables the brine to slowly flow into the electrolysis chamber, avoiding a relatively high concentration caused by a large amount of brine flowing into the electrolysis chamber in a short time.

[0037] 10. The electrolysis body includes the upper cover and the box body, with a very simple and compact overall structure and convenient assembly.

[0038] 11. The method for making disinfectant by the electrolysis device of the present invention includes the steps 1) - 5), realizing a way of automatically making disinfectant by the user adding salt. It is not only convenient to operate but also can ensure the disinfection effect of the disinfectant.

[0039] The following further describes the present invention in detail with reference to the drawings and embodiments; however, an electrolysis device, a method for making disinfectant, and a smart toilet of the present invention are not limited to the embodiments. Description of the Drawings

[0053] First Embodiment

[0054] Please refer to Figures 1 - 10 As shown in Figure 4, an electrolysis device of the present invention for a toilet includes an electrolysis body, which is provided with an electrolysis chamber 51 and a liquid outlet 54. The liquid outlet 54 communicates with the electrolysis chamber 51, and electrolysis electrodes 4 are installed in the electrolysis chamber 51; the electrolysis body is further provided with a brine chamber 52, a water inlet 53 and a salt addition port 11. The water inlet 53 and the salt addition port 11 both communicate with the brine chamber 52. A drainage member 2 is arranged between the brine chamber 52 and the electrolysis chamber 51. The brine in the brine chamber 52 is squeezed by the water entering the brine chamber 52 towards the drainage member 2 and flows towards the electrolysis chamber 51 through the liquid passing structure provided on the drainage member 2.

[0055] In this embodiment, as Figure 2 shown in Figure 5, the drainage member 2 is provided with a water flow groove 21 communicating with the electrolysis chamber 51. The water flow groove 21 communicates with the liquid passing structure and the water inlet 53, so that the brine entering the water flow groove 21 is carried away by the water entering the water flow groove 21 and flows into the electrolysis chamber 51. The liquid passing structure includes a number of liquid passing holes 22, and the aperture of each liquid passing hole 22 is 1.5 - 3 mm, and a preferred value of 2 mm is taken, but it is not limited thereto. In other embodiments, the number of the liquid passing holes is one.

[0056] In this embodiment, the drainage member 2 is located above the bottom of the brine chamber 52. The drainage member 2 is provided with a hollow water guiding column 26. As Figure 3 shown in Figure 6, the upper end of the water guiding column 26 communicates with the water flow groove 21, and the lower end of the water guiding column 26 extends downward into the brine chamber 52. As Figure 2 、 Figure 3 shown in Figures 7 and 8, an overflow wall 23 is provided in the water flow groove 21. The top end of the overflow wall 23 is lower than the top end of the groove wall of the water flow groove 21, and the overflow wall 23 divides the water flow groove 21 into a first groove body 211 and a second groove body 212. The first groove body 211 communicates with the water guiding column 26 and the water inlet 53, and the second groove body 212 communicates with the liquid passing structure and the electrolysis chamber 51.

[0057] In this embodiment, the water inlet 53 is located on the side wall of the electrolysis body. The drainage member 2 is provided with a downward extending water inlet column 24. AsFigure 3 As shown, the upper end of the water inlet column 24 communicates with the first tank body 211, and the lower end of the water inlet column 24 communicates with the water inlet 53.

[0058] In this embodiment, as Figure 2 shown, an overflow tank 25 is provided on the side wall of the second tank body 212, which communicates the second tank body 212 and the electrolysis chamber 51, and the bottom end thereof is higher than the bottom of the second tank body 212.

[0059] In this embodiment, the electrolysis device of the present invention further includes a main control board (not shown in the figure), and the main control board is electrically connected to the electrolysis electrode 4. The main control board emits an alarm signal when the electrolysis current of the electrolysis electrode 4 is lower than a preset value, and the main control board controls the electrolysis current of the electrolysis electrode 4 to be constant when the electrolysis current of the electrolysis electrode 4 is greater than or equal to the preset value. Specifically, when the concentration of the electrolyte in the electrolysis chamber 51 decreases, the electrolysis current of the electrolysis electrode 4 will decrease accordingly. When it is lower than the preset value, the main control board determines that the salt or saturated brine in the salt water chamber 52 has been used up and emits an alarm signal to notify the user. On the contrary, when the concentration of the electrolyte in the electrolysis chamber 51 is appropriate, the electrolysis current of the electrolysis electrode 4 is higher than the preset value. At this time, the control board controls the electrolysis current of the electrolysis electrode 4 to be a constant value (for example, 600 mA), so as to avoid the change of the electrolysis current with the change of the electrolyte concentration in the electrolysis chamber during the electrolysis process, thereby ensuring the stable disinfection performance of the disinfectant obtained after electrolysis. The preset value can be, for example, 400 mA.

[0060] In this embodiment, a liquid extraction pump 8 is further included, and the inlet of the liquid extraction pump 8 communicates with the liquid outlet 54. The main control board is electrically connected to the liquid extraction pump 8, and the main control board judges the liquid level of the electrolysis chamber 51 according to the electrolysis electrode 4 to control the closing time of the liquid extraction pump 8. A solenoid valve (not shown in the figure) is provided on the water inlet 53 or the water inlet pipeline connected thereto, and the main control board is electrically connected to the solenoid valve. The main control board judges the liquid level of the electrolysis chamber 51 according to the electrolysis electrode 4 to control the opening time of the solenoid valve.

[0061] In this embodiment, the electrolysis body is further provided with a port 55 for exhaust and overflow, and the port 55 communicates with the electrolysis chamber 51.

[0062] In this embodiment, the electrolysis body specifically includes a box body 5 and an upper cover 1. The box body 5 is provided with the electrolysis chamber 51 and the salt water chamber 52, and the drainage member 2 is arranged in the box body 5. Specifically, the drainage member 2 is placed on a partition wall 57 arranged inside the box body 5. The upper cover 1 is connected to the box body 5, and the upper cover 1 is provided with the salt adding port 11. As Figure 4 、 Figure 9 shown, the water inlet 53 is arranged on the side wall of the box body 5 to avoid occupying the space above the electrolysis body, and the inner end of the water inlet 53 extends upward to be butted against the lower end of the water inlet column 24.Figure 4 As shown, the through port 55 is provided on the box body 5. Specifically, a conduit 56 is provided in the electrolysis chamber 51 of the box body 5. The top end of the conduit 56 is higher than the highest liquid level of the electrolysis chamber 51. The top opening of the conduit 56 constitutes the through port 55, and the bottom end of the conduit 56 penetrates through the side wall of the box body 5. The electrolysis electrode 4 is specifically fixed in the electrolysis chamber 51 of the box body 5 through an electrode fixing flange 6 provided on the side wall of the box body 5. The electrode fixing flange 6 is connected with a protective cover 7. A pipe joint 3 is installed on the side wall of the box body 5. The pipe joint 3 has three joints 31, 32, and 33, which respectively correspond to the water inlet 53, the liquid outlet 54, and the through port 55 one by one.

[0063] In this embodiment, a salt adding hopper 12 is provided on the upper cover 1. The salt adding hopper 12 is generally in a funnel shape. The upper opening of the salt adding hopper 12 constitutes the salt adding port 11, and the lower opening of the salt adding hopper 12 leads to the brine chamber 52. A plurality of fixing holes are distributed along the circumferential direction of the top side wall of the salt adding hopper 12 for installation and positioning. The salt adding port 11 can be configured with an openable and closable lid.

[0064] For an electrolysis device of the present invention, during installation, first, the drainage member 2 and the electrolysis electrode 4 are installed in the box body 5, and the pipe joint 3 is fixed outside the side wall of the box body 5, as Figure 5 shown; then, the cover 1 is covered, and the cover is hermetically connected to the box body 5; finally, a liquid pumping pump 8 is installed at the lower part of the box body 5, as Figure 6 shown.

[0065] For an electrolysis device of the present invention, during application, it is installed in a smart toilet. Specifically, it is installed on the smart toilet lid of the smart toilet, as Figure 11 、 12 shown, and the outlet of the liquid pumping pump 8 is connected to a nozzle of the smart toilet for spraying disinfectant on its inner wall.

[0066] The working principle of the present invention is as follows:

[0067] The user adds table salt (i.e., sodium chloride) into the brine chamber 52 through the salt addition port 11 and manually activates the function of making disinfectant (i.e., sodium hypochlorite). When water enters for the first time, it enters the electrolysis chamber 51 and the brine chamber 52. After the electrolysis chamber 51 and the brine chamber 52 are both full of water, it flows out from the through port 55. At this time, part of the table salt in the brine chamber 52 dissolves locally (since the amount of added table salt is greater than the amount of table salt that can be dissolved in the water in the brine chamber 52, there will be a part of table salt crystals remaining at the bottom of the brine chamber 52 for continuous dissolution later, and the brine in the brine chamber 52 always remains saturated). After the water inlet is completed, the liquid extraction pump 8 is started to drain the water in the electrolysis chamber 51. Then, the solenoid valve is started to let water in again (the electrolysis capacity is controlled by controlling the water inlet time of the solenoid valve). The water enters the first tank body 211 through the water inlet column 24 of the water diversion member 2 and is divided into two paths. One path of water enters the brine chamber 52 through the water guiding column 26 and squeezes the saturated brine in the brine chamber 52 through each liquid passing hole 22 of the water diversion member 2 towards the second tank body 212. The other path of water overflows from the first tank body 211 to the second tank body 212 through the overflow wall 23, and at the same time takes away the saturated brine flowing into the second tank body 212 and flows into the electrolysis chamber 51 together with this saturated brine, as Figures 7 - 10 shown. After the water inlet time arrives, the solenoid valve closes and the water inlet stops. Specifically, after the liquid level in the electrolysis chamber 51 touches the electrolysis electrode 4, the main control board determines that there is liquid entering the electrolysis chamber 51, and after delaying for several seconds, controls the solenoid valve to close, and the water inlet is completed. At this time, there is a certain amount of electrolyte (i.e., saturated brine, also known as sodium chloride solution) in the electrolysis chamber 51, and the brine chamber 52 is replenished with water. These newly replenished waters dissolve part of the remaining table salt in the brine chamber 52, making the brine in the brine chamber 52 reach the saturated state again.

[0068] When electrolysis is started (the electrolysis timing can be controlled manually or set through a program, and it will be automatically started when the preset electrolysis time is reached), the electrolysis electrode 4 in the electrolysis chamber 51 is energized for a preset time to electrolyze the electrolyte, obtaining a disinfectant containing sodium hypochlorite. At the same time, the generated gases (hydrogen, a small amount of chlorine) are discharged through the through port 55. After the electrolysis is completed, disinfection is started: the liquid extraction pump 8 is started to extract the disinfectant in the electrolysis chamber 51 and spray it onto the inner wall surface of the toilet through the nozzle to implement full coverage disinfection of the inner wall surface of the toilet. As the disinfectant in the electrolysis chamber 51 is exhausted and the liquid level in the electrolysis chamber 51 is lower than the electrolysis electrode 4, the main control board determines that the disinfection spray is completed, delays for several seconds, and completes the disinfection process. At the same time, the main control board opens the solenoid valve and repeats the above water inlet process to replenish the electrolyte in the electrolysis chamber 51 and prepare for the next electrolysis and disinfection.

[0069] When the saturated salt water in the salt water chamber 52 is used up (at this time, the salt in the salt water chamber 52 has been completely dissolved), the concentration of the electrolyte in the electrolysis chamber 51 decreases, the electrolysis current of the electrolysis electrode 4 decreases, and after the electrolysis current decreases to the set value, the main control board determines that the salt and / or saturated salt water is used up, and sends an alarm signal to remind the user to add salt again.

[0070] The electrolysis device of the present invention uses salt added by the user to obtain salt water, and uses salt water as an electrolyte. The chlorine content is sufficient, which can ensure that the disinfectant obtained by electrolysis has a significant disinfection effect, and the disinfectant can be used as soon as it is prepared, avoiding reducing the disinfection effect. In addition, because the salt water in the salt water chamber 52 is squeezed toward the drainage member 2 by the water entering the salt water chamber 52, and flows to the electrolysis chamber 51 through the liquid flow structure provided by the drainage member 2, the present invention can not only replenish the salt water chamber 52, but also automatically replenish the electrolyte for the electrolysis chamber 51 before the salt added in the salt water chamber 52 is exhausted, and ensure that the concentration of the electrolyte (i.e., salt water) in the electrolysis chamber 51 can always be maintained within a stable range, thereby ensuring that the disinfection performance of the disinfectant obtained by electrolysis is stable.

[0071] See also Figure 11 , Figure 12 As shown, a smart toilet of the present invention comprises a toilet seat 9 and a smart toilet cover 10 arranged on the toilet seat 9, and also comprises an electrolysis device as described in the present invention above. The disinfectant obtained by electrolysis in the electrolysis chamber 51 of the electrolysis device is output and sprayed toward the inner wall surface of the toilet (i.e., the inner wall surface of the toilet seat 9) through a nozzle.

[0072] In this embodiment, the electrolysis device is specifically arranged at the bottom of the smart toilet cover 10, and the salt adding hopper 12 on its upper cover 1 is plugged into the make way hole 101 opened at the top of the smart toilet cover 10. When adding salt, it is only necessary to open the cover 20 set on the salt adding hopper 12.

[0073] The working process of the electrolysis device of the intelligent toilet of the present invention is as described above and will not be repeated here.

[0074] Embodiment 2

[0075] See also Figure 13As shown in the figure, an electrolysis device of the present invention is different from the electrolysis device described in the first embodiment above in that: the salt addition port 11, the water inlet 13, and the port 14 for exhaust and overflow are all provided on the upper cover 1 of the electrolysis body. In this way, the water guiding member 2 does not need to be provided with a water inlet column. When water enters, the water enters the water flow groove 21 of the water guiding member 2 from the water inlet 13 of the upper cover 1, and is divided into two paths in the water flow groove 21. One path of water enters the brine chamber 52 through the water guiding column 26 of the water guiding member 2, and squeezes the saturated brine in the brine chamber 52 into the water flow groove 21 through the liquid passing holes 22 of the water guiding member 2. The other path of water is mixed with the saturated brine entering the water flow groove 21 and flows into the electrolysis chamber 51 together.

[0076] An electrolysis device of the present invention has the same entire working process as that in the first embodiment above. Therefore, it will not be elaborated here.

[0077] A method for making disinfectant by using an electrolysis device of the present invention includes the following steps:

[0078] 1) Water enters through the water inlet, and part of the salt added to the brine chamber is dissolved to obtain saturated brine;

[0079] 2) Water enters through the water inlet, the water enters the brine chamber, squeezes the saturated brine in the brine chamber towards the water guiding member, and is guided to the electrolysis chamber through the water guiding member to add or supplement the electrolyte to the electrolysis chamber;

[0080] 3) When electrolysis is started, the electrolysis electrodes in the electrolysis chamber are energized for a preset time to obtain disinfectant;

[0081] 4) When disinfection is started, the disinfectant in the electrolysis chamber is discharged;

[0082] 5) Steps 2), 3), and 4) are repeatedly executed until the salt in the brine chamber is exhausted and / or the saturated brine in the brine chamber is used up.

[0083] In this embodiment, in step 2), the incoming water is divided into two paths.
