Dishwasher control method and control device and dishwasher

Abstract

The present invention provides a dishwasher control method and control device, and a dishwasher. The control method includes the following steps: controlling disinfectant water to enter the washing water holding space for disinfection; obtaining the water level of the disinfectant water; and when the water level of the disinfectant water exceeds a preset water level, turning on the controllable power supply to conduct electricity to the auxiliary anode, wherein the preset water level is higher than the lowest position of the auxiliary anode. In the present invention, because the controllable power supply continuously provides electrons to the inner container, even if the elemental iron in the inner container is oxidized to form iron ions, the continuous transport of electrons will quickly capture the newly oxidized iron ions, thereby being reduced again to elemental iron, thereby effectively preventing oxidation of the inner wall of the inner container.

Description

Technical Field

[0001] The present invention relates to the technical field of dishwashers, and in particular to a dishwasher control method and control device, and a dishwasher. Background Art

[0002] Dishwashers are very common appliances in the kitchen. They can be used to clean dishes, vegetables, fruits, and more. In the prior art, the main components of a dishwasher typically include an inner container assembly, a water cup assembly, a spray arm assembly, a filter assembly, a wash pump, a drain pump, and piping. In addition to cleaning dishes, dishwashers also need to eliminate bacteria and other substances that may be attached to them, thereby preventing infection.

[0003] Dishwashers currently on the market typically use high temperatures (usually around 70°C) for both the main wash and tableware disinfection. Some also include UVC disinfection lamps and the addition of silver ions to components to inhibit bacteria. While these disinfection methods eliminate bacteria and viruses, they can also leave residue inside the dishwasher. This residue can enter the human body along with the tableware, potentially causing adverse effects.

[0004] To this end, the existing technology usually uses electrolysis of salt water to prepare disinfectant water, and further acts on tableware to achieve the disinfection of tableware. Through the above method, the disinfectant water will decompose to form salt after use, and the final residue will not cause harm to the human body.

[0005] However, the disinfectant water obtained after oxidation contains a large amount of hypochlorite ions, which have strong oxidizing properties and are therefore prone to pitting corrosion on the inner wall of the dishwasher. This will first affect the morphology of the inner tank of the dishwasher. At the same time, after long-term pitting corrosion, through holes will form at the location of the pitting holes, causing leakage on the side wall of the inner tank. Summary of the Invention

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that the dishwasher is prone to pitting when being disinfected with highly oxidizing disinfectant water.

[0007] To this end, the present invention provides a method for controlling a dishwasher, the dishwasher comprising an inner container having a wash water storage space therein, an auxiliary anode disposed within the wash water storage space, the auxiliary anode being connected to an anode of a controllable power supply, and a cathode of the controllable power supply being connected to the inner container via a wire; the method comprising the following steps:

[0008] Control the disinfection water to enter the washing water holding space for disinfection; obtain the water level of the disinfection water; when the water level of the disinfection water is higher than the preset water level, turn on the controllable power supply to turn on the auxiliary anode, and the preset water level is higher than the lowest position of the auxiliary anode.

[0009] The control method provided by the present invention also includes the following steps: judging whether the disinfection is completed; if the disinfection is completed, introducing clean water into the inner tank; judging whether the clean water is introduced normally; if the clean water is introduced normally, controlling the disinfection water in the inner tank to be discharged and turning off the controllable power supply.

[0010] The control method provided by the present invention further includes: if the clean water is not introduced normally, stopping the discharge of the disinfectant water in the inner tank and turning on the controllable power supply.

[0011] The control method provided by the present invention further includes: after the disinfecting water is completely discharged, introducing clean water into the inner tank, stopping the discharge of the clean water in the inner tank, and allowing the clean water to wash the inner tank.

[0012] The control method provided by the present invention further includes: after the washing of the inner tank is completed, controlling the clean water in the inner tank to be discharged, and controlling the ventilation device to start.

[0013] The present invention also provides a dishwasher control device, including: a water flow module, used to control the disinfection water to enter the washing water holding space for disinfection; a water level acquisition module, used to obtain the water level of the disinfection water; and a power supply module, used to turn on the controllable power supply to turn on the auxiliary anode when the water level of the disinfection water is higher than a preset water level.

[0014] The dishwasher control device provided by the present invention also includes a first judgment module for judging whether disinfection is completed; a clean water introduction module for introducing clean water into the inner tank after disinfection is completed; a second judgment module for judging whether the clean water is introduced normally; and a drainage module for controlling the discharge of the disinfected water in the inner tank.

[0015] The dishwasher control device provided by the present invention further includes: a drainage stop module, which is used to stop the discharge of the disinfectant water in the inner tank and turn on the controllable power supply when the clean water is not flowing in normally.

[0016] The present invention provides a dishwasher, comprising: an inner tank, a water cup being provided on the inner tank, a water inlet pipe and a water outlet pipe being provided on the water cup, the water inlet pipe being provided with a water inlet solenoid valve, and the water outlet pipe being provided with a water outlet device; a flow meter being provided inside the dishwasher and suitable for detecting water entering the water inlet pipe; an electron generator being connected to the inner tank via a wire, an auxiliary anode being provided on the anode of the electron generator, the auxiliary anode being suitable for contacting with washing water in the water cup; and a controller comprising a memory and a processor, the memory storing a computer program, and when the computer program is executed, the dishwasher executes the dishwasher control method provided by the present invention.

[0017] The technical solution of the present invention has the following advantages:

[0018] 1. The present invention provides a dishwasher control method for a dishwasher, wherein the dishwasher includes an inner tank having a wash water holding space therein, an auxiliary anode is provided in the wash water holding space, the auxiliary anode is connected to the anode of a controllable power supply, and the cathode of the controllable power supply is connected to the inner tank via a wire; the method comprises the following steps: controlling disinfectant water to enter the wash water holding space for disinfection; obtaining the water level of the disinfectant water; when the water level of the disinfectant water exceeds a preset water level, turning on the controllable power supply to conduct the auxiliary anode, wherein the preset water level is higher than the lowest position of the auxiliary anode.

[0019] In the prior art, since the inner liner is made of metal and the disinfectant itself is highly oxidizing, when the disinfectant enters the inner liner, the inner liner is easily oxidized to form pitting pits.

[0020] In the present invention, since the controllable power supply continuously provides electrons to the inner tank, even if the elemental iron in the inner tank is oxidized to form iron ions, the iron ions that have just been oxidized will be quickly captured due to the continuous transport of electrons, and then reduced again to elemental iron, thereby effectively preventing the inner wall of the inner tank from being oxidized.

[0021] 2. The control method provided by the present invention further includes stopping the discharge of the disinfectant water in the inner tank and turning on the controllable power supply if the clean water is not introduced normally.

[0022] In dishwashers, there may be situations where clean water cannot flow into the dishwasher, such as when the tap water is out of power or the water inlet pipe is clogged. If clean water cannot flow into the inner tank normally, and if the disinfectant in the inner tank is still discharged to the outside, some disinfectant will still remain in the inner tank. Due to the low liquid level in the inner tank, even if the controllable power is turned on, the electrolytic cell cannot be fully formed between the auxiliary anode and the inner tank, and corrosion will continue to occur, causing corrosion to the inner tank.

[0023] In the present invention, in order to avoid the above situation, it is first determined whether the clean water can be normally introduced into the inner tank. If the clean water cannot be normally introduced for some reason, the drainage operation of the inner tank is stopped. Since the liquid level of the disinfectant water is high, a stable electrolytic cell can be formed between the auxiliary anode, the inner tank and the controllable power supply. At this time, it is only necessary to control the controllable power supply to be normally energized to avoid corrosion that occurs when the disinfectant water is not fully discharged.

[0032] 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.

[0033] Example 1

[0034] This embodiment provides a method for controlling a dishwasher. The dishwasher includes an inner container made of stainless steel and having a wash water storage space therein. An auxiliary anode is disposed within the wash water storage space. The auxiliary anode is connected to an anode of a controllable power supply, and a cathode of the controllable power supply is connected to the inner container via a wire.

[0035] like Figure 2 As shown, the method includes the following steps:

[0036] S1. Control disinfectant water entering the washing water receiving space for disinfection;

[0037] In this embodiment, there is no restriction on the source of the disinfectant water, which can be prepared in advance and then directly introduced into the water cup through an external pipeline.

[0038] As a preferred embodiment, in this embodiment, a disinfectant water generating device is integrated in the dishwasher, and the disinfectant water preparation operation can be completed first in the dishwasher, and then the prepared disinfectant water is directly introduced into the inner tank to perform the disinfection operation on the inner tank.

[0039] Specifically, the composition of the disinfectant is not limited. Preferably, the disinfectant is obtained by oxidizing sodium chloride. After the sodium chloride itself is oxidized, sodium hypochlorite is formed. The sodium hypochlorite solution itself has strong oxidizing properties. The specific reaction process is as follows:

[0040] Cathode: 2Cl - -2e - =Cl2

[0041] Anode: 2H2O+2e - =H2+2OH -

[0042] Overall reaction: 2Cl -+ 2H2O=H2+Cl2+2OH -

[0043] A disproportionation reaction will occur between chlorine and water: Cl2+H2O=HCl+HClO. The produced HClO itself has certain oxidizing properties, thereby achieving the killing effect on bacteria and viruses.

[0044] In this embodiment, the salt used is NaCl, which is non-toxic and stable in nature, not prone to deterioration, and convenient for storage and electrolytic disinfection. Other chlorates, such as KCl and CaCl2, are not recommended because they can cause certain harm to the human body.

[0045] When the disinfectant water enters the washing water holding space, it can kill viruses and bacteria through its own high oxidizing properties.

[0046] S2. Get the water level of the disinfectant water;

[0047] There is no limitation on the method of obtaining the water level of the disinfecting water. As a preferred embodiment, a water level sensor can be provided inside the washing water holding space to obtain the liquid level height inside the washing water holding space through the water level sensor.

[0048] As a variation, the liquid level can also be determined by monitoring the volume of water entering the washing water holding space. At this time, the function between the liquid level and the volume can be pre-placed into the controller, and the volume of water entering the washing water holding space can be calculated by the flow meter. The flow meter further transmits the signal to the controller. When the detected volume of water meets the preset volume, the flow meter sends the signal to the controller, and the controller further controls to stop the water intake.

[0049] S3. When the water level of the disinfectant water is higher than a preset water level, the controllable power supply is turned on to turn on the auxiliary anode, and the preset water level is higher than the lowest position of the auxiliary anode.

[0050] Specifically, the controllable power source is weak electricity, which can be the mains electricity connected to the dishwasher, and then converted into weak electricity by a converter, or a battery, which is used to realize power supply operation.

[0051] At the same time, the auxiliary anode can be placed horizontally, vertically or tilted. When placed vertically or tilted, normal operation can be achieved as long as the water level of the disinfectant water does not exceed the root of the auxiliary anode.

[0052] In this embodiment, since the disinfectant itself is highly oxidizing, it will cause the inner wall of the inner container to oxidize, causing the elemental iron to be converted into iron ions. The specific reaction is as follows:

[0053] Fe-3e - =Fe 3+

[0054] In this embodiment, an electrolytic cell is formed between the auxiliary anode, disinfectant water, the inner tank, and the controllable power supply. The reactions of the cathode and anode of the electrolytic cell are as follows:

[0055] Cathode: Fe 3+ +3e - =Fe

[0056] Anode: 2H2O=2H2+O2

[0057] In this embodiment, since the controllable power supply continuously provides electrons to the inner tank, even if the elemental iron in the inner tank is oxidized to form iron ions, the iron ions that have just been oxidized will be quickly captured due to the continuous transport of electrons, and then reduced again to elemental iron, thereby effectively preventing the inner wall of the inner tank from being oxidized.

[0058] Specifically, the washing water receiving space itself can be set as a water cup, such as Figure 1 As shown, the water cup is arranged below the inner liner. When water is introduced into the inner liner, the water will gather inside the water cup, thereby realizing the water collection operation.

[0059] As for the auxiliary anode, it is made of inert materials, such as carbon rods, inert metals such as copper, etc.

[0060] Furthermore, after a period of disinfection, the present embodiment further includes the following steps:

[0061] S4. Determine whether disinfection is completed;

[0062] In this embodiment, the method for determining whether the disinfection is completed is not limited. As an implementation method, the completion of the disinfection can be determined by the reaction time. For example, if the disinfection time is set to 5 minutes, when the time reaches five minutes, it is determined that the disinfection has been fully carried out.

[0063] As another embodiment, the disinfection can be determined by detecting the number of viruses or bacteria in the inner container. For example, when the number of viruses or bacteria is lower than a certain set value, the remaining bacteria or viruses will not cause harm to the human body, and the disinfection can be determined to be complete.

[0064] S5. If disinfection is complete, add clean water to the inner tank;

[0065] After the disinfection is completed, the inner tank needs to be cleaned as necessary to avoid the residue of the disinfectant itself, that is, the inner tank needs to be rinsed.

[0066] In this embodiment, the inner tank is connected to a water inlet pipe, which can be connected directly to a faucet or to a water storage device such as a water tank. A valve is also provided on the water inlet pipe. The valve can be manual or electric. When an electric valve is used, it is connected to the controller, thereby facilitating the controller to immediately control the flow of clean water into the inner tank.

[0067] S6. Determine whether the clean water is normally introduced;

[0068] In this embodiment, the flow of clean water is judged by a flow meter. If water passes through the flow meter, the impeller and magnet inside the flow meter rotate under the drive of water pressure, generating a circulating alternating magnetic field. The reed switch counts along with the circulating alternating magnetic field and generates a water signal.

[0069] S7. If the clean water flows in normally, the disinfectant water in the inner tank is controlled to be discharged and the controllable power supply is turned off.

[0070] Specifically, after the clean water can flow in normally, the disinfectant water in the inner tank is discharged, and then the clean water is passed into the inner tank in batches, and the inner tank is repeatedly flushed.

[0071] Furthermore, when clean water can flow into the inner tank normally, it also includes: after the disinfection water is completely discharged, clean water is introduced into the inner tank, and the discharge of the clean water in the inner tank is stopped, so that the clean water washes the inner tank.

[0072] At this time, the dishwasher will enter the rinsing stage. After rinsing, the concentration of the disinfectant water can be reduced, thereby preventing the disinfectant water from corroding the inner tank.

[0073] Furthermore, after the clean water has fully rinsed the inner tank, in order to prevent the residual clean water from causing rust to the inner tank, the following steps are also included: after the washing of the inner tank is completed, the clean water in the inner tank is controlled to be discharged, and the ventilation device is controlled to start.

[0074] The ventilation device itself is set inside the dishwasher. When the ventilation device is started, the air flow it forms will quickly blow the clean water to the outside of the dishwasher.

[0075] S8. If the clean water is not flowing in normally, stop draining the disinfectant water in the inner tank and turn on the controllable power supply.

[0076] In this embodiment, there may be situations where clean water cannot flow into the dishwasher, such as a power outage in the water supply or a blockage in the water inlet pipe. If clean water cannot flow into the inner tank normally, and if the disinfectant in the inner tank is still discharged to the outside, some disinfectant will still remain in the inner tank. Due to the low liquid level in the inner tank, even if the controllable power supply is turned on, an electrolytic cell cannot be fully formed between the auxiliary anode and the inner tank, and corrosion will continue to occur, causing damage to the inner tank.

[0077] In this embodiment, in order to avoid the above situation, it is first determined whether the clean water can be normally passed into the inner tank. If the clean water cannot be normally passed for some reason, the drainage operation of the inner tank is stopped. Since the liquid level of the disinfectant water is high, a stable electrolytic cell can be formed between the auxiliary anode, the inner tank and the controllable power supply. At this time, it is only necessary to control the controllable power supply to be normally energized to avoid corrosion that occurs when the disinfectant water is not fully discharged.

[0078] Example 2

[0079] This embodiment provides a dishwasher, such as Figure 1 As shown, including:

[0080] The inner liner 1 is provided with a water cup 11, and the water cup 11 is provided with a water inlet pipe 4 and a water outlet pipe 5.

[0081] Specifically, the inner liner 1 is made of metal, and a water cup 11 is provided at the bottom of the inner liner 1. The water cup 11 can store water. Figure 1 As shown, the water cup 11 itself is configured in a conical shape, so that the water entering the inner container 1 can be fully utilized.

[0082] The water inlet pipe 4 is provided with a water inlet solenoid valve 6, and the water outlet pipe 5 is provided with a water outlet device;

[0083] like Figure 1 As shown, a water inlet pipe 4 is provided on the water cup 11, and the water inlet pipe 4 is suitable for introducing clean water. The water inlet pipe 4 itself is connected to tap water or a water tank, and the clean water can be used to rinse the inner container 1;

[0084] The water outlet device can be a water outlet solenoid valve or a water pump. Through the water outlet solenoid valve and the water pump, the water formed in the water cup 11 after washing can be discharged to the outside.

[0085] A flow meter 8 is provided inside the dishwasher and is suitable for detecting water entering the water inlet pipe 4;

[0086] An electron generating device is connected to the inner container 1 via a wire 14. An auxiliary anode 2 is provided on the anode of the electron generating device. The auxiliary anode 2 is suitable for contacting the washing water in the water cup 11.

[0087] Specifically, the auxiliary anode 2 itself is made of an inert material, such as a carbon rod, an inert metal, such as copper, etc., so that a stable chemical reaction can be performed on the auxiliary anode 2 .

[0088] When the dishwasher is drained and the tap water is cut off, the inner tank 1 lacks water, that is, the electronic anode anti-corrosion circuit is in an open circuit state, and the anti-corrosion function fails.

[0089] In order to play an anti-corrosion role even when the tap water is cut off, before the water outlet device drains the disinfectant water 12, the water inlet solenoid valve 6 is opened for a period of time, such as 10 seconds. If there is water passing through the flow meter 8, the impeller and magnet inside the flow meter 8 rotate under the drive of water pressure, generating a cyclic alternating magnetic field. The reed switch counts along with the cyclic alternating magnetic field and generates a water signal. The signal is transmitted to the control main board. After the signal is processed by the control main board, the control main board issues a drainage instruction, and the water outlet device will execute the drainage instruction to drain the disinfectant water 12. After drainage is completed, the drain pump 7 stops working, and then the water inlet solenoid valve 6 is opened to introduce clean water into the inner tank 1 to continue the subsequent rinsing and drying program until the program is completed.

[0090] If no water passes through the flow meter 8, the impeller and magnet inside the flow meter 8 will not rotate, and the reed switch cannot sense the cyclic alternating magnetic field signal. At this time, the flow meter 8 will generate a water shortage signal, which is transmitted to the control main board. After the signal is processed by the control main board, the control main board issues a drainage instruction, and the water outlet device stops working. Disinfectant water 12 with a certain liquid level remains in the water cup 11 and the inner tank 1. The disinfectant water 12 connects the electronic auxiliary anode 2, the inner tank 1, and the controllable power supply 3 in series to form an electronic circuit, and the electronic anti-corrosion continues to work.

[0091] The controller includes a memory and a processor. The memory stores a computer program. When the computer program is executed, the dishwasher executes the dishwasher control method described in Example 1.

[0092] In this embodiment, a bowl basket 9 is provided in the inner container 1. Figure 1 As shown, a spray arm 10 is provided below the bowl basket 9. Water in a water cup 11 enters the spray arm 10, spraying the tableware in the bowl basket 9. To prepare disinfectant 12, an electrolytic water tank 13 is provided on the side wall of the inner container 1. Salt water is electrolyzed in the electrolytic water tank 13 to produce disinfectant 12, which then flows into the inner container 1 through a disinfectant inlet pipe 15, thereby participating in the disinfection reaction.

[0093] Example 3

[0094] This embodiment provides a dishwasher control device, including: a water flow module, used to control the entry of disinfectant water into the washing water holding space for disinfection; a water level acquisition module, used to obtain the water level of the disinfectant water; and a power supply module, used to turn on the controllable power supply to turn on the auxiliary anode when the water level of the disinfectant water is higher than a preset water level.

[0095] The dishwasher control device provided in this embodiment also includes a first judgment module for judging whether the disinfection is completed; a clean water introduction module for introducing clean water into the inner tank after the disinfection is completed; a second judgment module for judging whether the clean water is introduced normally; and a drainage module for controlling the discharge of the disinfected water in the inner tank.

[0096] The dishwasher control device provided in this embodiment further includes: a drainage stop module, which is used to stop the drainage of the disinfectant water in the inner tank and turn on the controllable power supply when the clean water is not flowing in normally.

[0097] 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.
