Description

Technical Field

[0001] This invention relates to the field of dishwasher technology, and in particular to a disinfectant preparation logic and a dishwasher. Background Technology

[0002] With the improvement of living standards, dishwashers have gradually entered ordinary households, freeing up our hands and improving our quality of life. Typically, the main core components of a dishwasher include: the inner drum assembly, water cup assembly, spray arm assembly, filter assembly, washing pump, drain pump, and piping. Currently, dishwashers on the market generally use high temperatures (around 70℃) for main cleaning and dish sterilization. Some also incorporate UVC ultraviolet light sterilization, silver ion antibacterial agents added to parts (this method has an expiration date and loses its effectiveness after a period of use), high-temperature steam sterilization, and hot air drying. These sterilization methods primarily disinfect the surface of the dishes and are not very effective for the internal, unseen parts.

[0003] Currently, patent CN116019406A proposes a disinfecting dishwasher that uses a disinfectant solution to disinfect and clean the dishwasher. However, it does not explain how to determine if the disinfectant solution is fully prepared. If it is determined solely by the preparation time, it may lead to waste or the disinfectant solution not being fully prepared, resulting in substandard disinfection. Summary of the Invention

[0004] To overcome the shortcomings of existing disinfection dishwashers, which do not provide specific logic for determining whether the disinfectant solution is fully prepared, and which may lead to waste or the disinfectant solution not being fully prepared, resulting in substandard disinfection effect, the present invention aims to provide a disinfectant solution preparation logic and a dishwasher.

[0005] The technical solution adopted by this invention to solve its technical problem is: a disinfectant preparation logic, including the following steps:

[0006] To determine the required amount of disinfectant ingredients for a dishwasher;

[0007] The initial electrolysis working time is determined based on the content of the disinfectant component.

[0008] When the electrolysis time of the electrolysis device reaches the initial electrolysis working time, the real-time ozone concentration value in the air outlet pipe of the dishwasher water tank is obtained.

[0009] The real-time ozone concentration value is compared with the preset ozone concentration value to determine whether the disinfectant solution has been prepared.

[0010] When the real-time ozone concentration is less than or equal to the preset ozone concentration, the disinfectant solution is considered to be ready.

[0011] As a further improvement of the present invention, it also includes: when the real-time ozone concentration value is greater than the preset ozone concentration value, it is determined that the disinfectant solution has not been fully prepared.

[0012] As a further improvement of the present invention: when the real-time ozone concentration value is greater than the preset ozone concentration value, the following is also included:

[0013] Get the current time remaining until the dishwasher reaches the sanitizing stage;

[0014] Determine if the time remaining until the dishwasher's sterilization stage is less than the preset time;

[0015] If not, continue monitoring the real-time ozone concentration in the dishwasher's water tank exhaust pipe;

[0016] If so, extend the washing cycle time of the dishwasher and continue to monitor the real-time ozone concentration in the vent pipe of the dishwasher's water tank.

[0017] As a further improvement of the present invention: after the real-time ozone concentration value is less than or equal to the preset ozone concentration value, the following is also included:

[0018] Determine if the time remaining until the dishwasher's sterilization stage is less than the preset time;

[0019] If so, add the disinfectant from the dishwasher's water tank into the dishwasher's inner tub for disinfection and washing;

[0020] If not, continue monitoring the real-time ozone concentration in the dishwasher's water tank exhaust pipe.

[0021] As a further improvement of the present invention, it also includes: after the dishwasher enters the disinfection stage and the disinfectant in the dishwasher water tank is discharged, the water tank water inlet and the air pump are controlled to work until the real-time ozone concentration value is detected to be less than the preset concentration threshold, then the water tank drainage and the air pump are controlled to stop working.

[0022] As a further improvement of the present invention, obtaining the required disinfectant content for the dishwasher specifically includes: obtaining the water inlet volume of the dishwasher water tank, and calculating the required disinfectant content based on the water inlet volume.

[0023] As a further improvement of the present invention, it also includes: installing an ozone concentration detection device in the gas storage tank of the dishwasher water tank, and detecting the real-time ozone concentration value through the ozone concentration detection device.

[0024] As a further improvement of the present invention, it also includes: when the electrolysis time of the electrolysis device reaches the initial electrolysis working time, controlling the electrolysis device to shut down.

[0025] As a further improvement of the present invention: before the electrolysis time of the electrolysis device reaches the initial electrolysis working time, it also includes: a washing stage before the dishwasher enters the disinfection wash, during which the electrolysis device of the disinfection module starts working and the air pump continues to work.

[0026] Based on the same inventive concept, the present invention also provides a dishwasher, including a disinfectant preparation logic as described above.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] This invention installs an ozone concentration detection device in the vent pipe of the water tank to detect the ozone concentration escaping from the vent pipe, thereby determining whether the ozone and other disinfecting components in the disinfectant solution in the dishwasher water tank are fully dissolved and meet the qualified standard, thus determining that the disinfectant solution preparation is complete. This solves the technical problem in the prior art that does not mention whether the disinfectant solution preparation is complete and only judges based on the preparation time, which is inaccurate. It avoids waste or the phenomenon that the disinfectant solution is not fully prepared, resulting in substandard disinfection effect. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0034] To address the technical problems in existing dishwashers regarding how to determine when the disinfectant solution preparation is complete (meets the acceptable standard), how to ensure disinfection effectiveness, and how to avoid waste of disinfectant solution, the present invention will be further described below with reference to the accompanying drawings and embodiments:

[0035] Example 1

[0036] like Figures 1-4 As shown, this embodiment discloses a disinfectant preparation logic, including the following steps:

[0037] S1: Obtain the required amount of disinfectant ingredients for the dishwasher;

[0038] Preferably, obtaining the required disinfectant component content for the dishwasher specifically includes: obtaining the water inlet volume of the dishwasher's water tank, and calculating the required disinfectant component content based on the water inlet volume.

[0039] S2: Determine the initial electrolysis working time based on the content of the disinfectant component;

[0040] S3: When the electrolysis time of the electrolysis device reaches the initial electrolysis working time, obtain the real-time ozone concentration value in the air outlet pipe of the dishwasher water tank;

[0041] Preferably, the method further includes: controlling the electrolysis device to shut down when the electrolysis time of the electrolysis device reaches the initial electrolysis working time.

[0042] Preferably, it further includes: installing an ozone concentration detection device in the gas storage tank of the dishwasher water tank, and detecting the real-time ozone concentration value through the ozone concentration detection device.

[0043] Since the ozone and other disinfecting components produced by the electrolysis device cannot be completely dissolved in water, some of the ozone and other bactericidal components produced by electrolysis dissolve in water, while the remaining bactericidal components can enter the exhaust pipe with the air. Therefore, in this embodiment, an ozone concentration detection device is installed in the exhaust pipe to detect the amount of residual ozone, thereby determining whether the ozone content in the disinfectant is qualified.

[0044] More preferably, before the electrolysis time of the electrolysis device reaches the initial electrolysis working time, it also includes: a washing stage before the dishwasher enters the disinfection wash, during which the electrolysis device of the disinfection module starts working and the air pump continues to work.

[0045] S4: Compare the real-time ozone concentration value with the preset ozone concentration value to determine whether the disinfectant solution has been prepared.

[0046] S41: When the real-time ozone concentration value is less than or equal to the preset ozone concentration value, the disinfectant preparation is considered complete.

[0047] Preferably, after the real-time ozone concentration value is less than or equal to the preset ozone concentration value, the method further includes:

[0048] S411: Determine if the time remaining until the dishwasher's sterilization stage is less than the preset time;

[0049] S412: If so, add the disinfectant from the dishwasher water tank into the dishwasher tub for disinfection and washing.

[0050] S413: If not, continue to monitor the real-time ozone concentration in the vent pipe of the dishwasher water tank.

[0051] Preferably, it also includes: S42: when the real-time ozone concentration value is greater than the preset ozone concentration value, it is determined that the disinfectant has not been fully prepared.

[0052] More preferably, when the real-time ozone concentration value is greater than the preset ozone concentration value, the following is also included:

[0053] S421: Get the current time remaining until the dishwasher's sanitizing stage;

[0054] S422: Determine whether the time remaining until the dishwasher's sterilization stage is less than the preset time;

[0055] S423: If not, continue to monitor the real-time ozone concentration in the vent pipe of the dishwasher water tank;

[0056] S424: If so, control the dishwasher to extend the washing cycle time and continue to monitor the real-time ozone concentration in the dishwasher's water tank exhaust pipe.

[0057] More preferably, it also includes: S5: After the dishwasher enters the disinfection stage and the disinfectant in the dishwasher's water tank is drained, the system controls the water tank to fill and the air pump to operate until the real-time ozone concentration value is detected to be lower than a preset concentration threshold, at which point the system controls the water tank to drain and the air pump to stop operating. This dissolves the ozone in the pipes by refilling the water tank, thus preventing air pollution.

[0058] The first function of the ozone concentration detection device of the present invention is to calculate the amount of ozone in the disinfection solution by measuring the amount of residual ozone, thereby determining whether the disinfection solution is qualified (i.e., the disinfection solution preparation is completed as referred to in the present invention). The second function is to prevent excessive residual ozone from causing leakage and air pollution.

[0059] An ozone concentration detection device is installed in the vent pipe of the water tank to detect the ozone concentration escaping from the vent pipe. This allows for the calculation of the ozone content in the disinfectant solution within the water tank, thus determining whether the disinfectant solution has been prepared and meets the required standards.

[0060] Example 2

[0061] like Figures 1-4 As shown, this embodiment discloses a disinfectant preparation logic, including the following steps:

[0062] S1: Obtain the water inlet volume of the dishwasher water tank, and determine the required disinfectant content based on the water inlet volume;

[0063] According to relevant research, high-voltage electrolysis of air produces disinfectant components such as ozone. Dissolving these components in water produces a disinfectant solution, which only has a disinfecting effect when the concentration of the disinfectant components reaches a certain level.

[0064] The ratio of disinfectant components to water in a disinfectant solution must meet a qualified standard to confirm that the disinfectant solution is ready. Accordingly, the water intake of different dishwasher tanks also requires a specific value or range of preset ozone concentration values.

[0065] The water volume of the dishwasher's water tank varies depending on the type and quantity of tableware being cleaned, as well as the cleaning and sanitizing mode. It also depends on the user's custom settings. In other words, the water volume of the dishwasher's water tank can be selected.

[0066] S2: Calculate the initial electrolysis working time t0 of the electrolysis device based on the content of the disinfectant component;

[0067] Since research has shown that the amount of ozone produced by electrolysis is constant within a certain time, meaning that there is a one-to-one correspondence between the working time of the electrolysis device and the amount of ozone produced, this embodiment calculates the initial electrolysis working time t0 of the electrolysis device based on the ozone content in the disinfection components required for dishwasher disinfection.

[0068] Before the dishwasher enters the washing stage, the electrolysis device of the disinfection module starts working, electrolyzing the air to produce ozone and other bactericidal components (disinfectants). The air pump continues to work to introduce the ozone and other bactericidal components into the dishwasher's water tank through the air inlet pipe.

[0069] In this embodiment, the ozone in the disinfection component is generated by an electrolysis device. Electrolysis of air produces bactericidal components such as single oxygen atoms, ozone ion clusters, hydrogen peroxide ion clusters, hydroxyl groups, and nitrosamines. The prepared ozone is then introduced into the water tank through an air pump connected to an air inlet pipe.

[0070] An air pump rapidly dissolves ozone in the water in the tank to form a disinfectant solution. In addition, the disinfection module includes an electrolysis device and a water tank.

[0071] S3: When the electrolysis time of the electrolysis device reaches the initial electrolysis working time t0, the electrolysis device is controlled to shut down, and the ozone concentration detection device detects the real-time ozone concentration value C in the air outlet pipe of the dishwasher water tank.

[0072] Since the ozone and other disinfecting components produced by the electrolysis device cannot be completely dissolved in water, some of the ozone and other bactericidal components produced by electrolysis dissolve in water, while the remaining bactericidal components can enter the exhaust pipe with the air. Therefore, in this embodiment, an ozone concentration detection device is installed in the exhaust pipe to detect the amount of residual ozone, thereby determining whether the ozone content in the disinfectant is qualified.

[0073] S4: Compare the real-time ozone concentration value C with the preset ozone concentration value C0, and determine whether the real-time ozone concentration value C is greater than the preset ozone concentration value C0, so as to determine whether the disinfectant has been prepared.

[0074] In this embodiment, based on the real-time ozone concentration value C and the preset ozone concentration value C0, the amount of ozone prepared after the initial electrolysis working time t0 of the electrolysis device is sufficient to meet the ozone component content required for the influent flow, and thus determine whether the disinfectant solution has been prepared.

[0075] S41: If the real-time ozone concentration value C is less than or equal to the preset ozone concentration value C0, proceed to S411;

[0076] S411: Determine whether the time remaining until the dishwasher's sterilization stage is less than the preset time t1;

[0077] Specifically, when C≤C0, it is determined that the disinfectant solution in the dishwasher water tank has been prepared, and the real-time ozone concentration value in the air outlet pipe of the dishwasher water tank is then monitored.

[0078] S412: If the time remaining until the dishwasher's sterilization stage is less than the preset time t1, add the disinfectant from the dishwasher's water tank into the dishwasher's inner tub for sterilization and washing.

[0079] S413: If the time remaining until the dishwasher's sterilization stage is greater than or equal to the preset time t1, continue to monitor the real-time ozone concentration in the dishwasher's water tank's exhaust pipe.

[0080] S42: If the real-time ozone concentration value C is greater than the preset ozone concentration value C0, proceed to S422;

[0081] S422: Determine whether the time remaining until the dishwasher sterilization stage is less than the preset time t1;

[0082] Specifically, when C > C0, it is determined that the disinfectant solution in the dishwasher's water tank has not been fully prepared, meaning that the amount of bactericidal components such as ozone dissolved in the water is insufficient.

[0083] S423: If the time remaining until the dishwasher's sterilization stage is greater than or equal to the preset time t1, continue to monitor the real-time ozone concentration C in the dishwasher's water tank's exhaust pipe.

[0084] S424: If the time remaining until the dishwasher's sterilization stage is less than the preset time t1, control the dishwasher to extend the washing stage time, and then continue to detect the real-time ozone concentration value C in the dishwasher's water tank's exhaust pipe.

[0085] The ozone and other disinfecting components produced by electrolysis require a certain amount of time to dissolve in water. Therefore, once it is determined that the ozone and other disinfecting components are fully dissolved in the water, the real-time ozone concentration value C should continue to be monitored. When the time remaining until the disinfection stage is less than the preset time t1, the interval is short. To ensure that the ozone and other disinfecting components are fully dissolved in the water, the washing stage time of the dishwasher needs to be extended.

[0086] It should be noted that even if some of the calculated disinfectant content overflows from the vent pipe, the remaining disinfectant content can still be fully dissolved in the dishwasher's water intake to generate a qualified disinfectant solution.

[0087] Preferably, it also includes: S5: After the dishwasher enters the disinfection stage and the disinfectant in the dishwasher water tank is discharged, the water tank is controlled to fill and the air pump is operated until the real-time ozone concentration value is detected to be less than the preset concentration threshold, then the water tank is controlled to drain and the air pump is stopped.
