Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.
Fig. 1 schematically shows a structural diagram of an electrode cleaning device for household appliances according to an embodiment of the present invention. As shown in fig. 1, in an embodiment of the present invention, there is provided a household electrical appliance electrode cleaning apparatus, including a ph detecting device 101, an electrolyzing device 102, a solution storage device 103, a water pump 104, and a processor 105, wherein:
the pH value detection device 101 is used for detecting the pH value of liquid at the anode water outlet end of the electrolysis device;
an electrolysis apparatus 102 for producing a cleaning solution;
a solution storage device 103 for storing a cleaning solution;
the water pump 104 is used for guiding the cleaning solution in the solution storage device to the water inlet end of the electrolysis device;
a processor 105 configured to: controlling the electrolytic equipment to start to manufacture the cleaning solution under the condition that the pH value exceeds a first preset pH range; and under the condition that the solution amount of the cleaning solution in the solution storage equipment reaches a preset storage threshold value, controlling the water pump to be started so as to clean the cathode water outlet end of the electrolysis equipment through the cleaning solution.
As shown in fig. 1, there is provided an electrode cleaning apparatus for home appliances, which is used for cleaning a cathode terminal of an electrolysis device included in the home appliance. Specifically, as shown in fig. 1, the electrode cleaning device for household appliances comprises a ph detection device 101, an electrolysis device 102, a solution storage device 103, a water pump 104, and a processor 105. At the anode water outlet end of the electrolysis device 102, a pH value detection device 101 is installed. The anode water outlet end of the electrolysis device is also connected with a solution storage device 103, the other end of the solution storage device 103 is connected with a water pump 104, the water pump 103 is connected with the water inlet end of the electrolysis device 102, and the devices can be controlled by a processor 105.
Specifically, the electrolytic action of the electrolytic medium by the electrolysis device 102 produces the cleaning solution. The pH (pH value) of the aqueous solution exiting from the anode of the electrolysis apparatus may be first determined by the pH value detection apparatus 101. Under the condition that the electrolysis device 102 is normally operated and the water inlet flow rate is maintained at a normal level, the ph value of the water outlet at the anode end is usually lower than the preset first ph range. At this time, it indicates that the cathode side water outlet of the electrolysis apparatus 102 can be operated normally. If the pH value detected by the pH value detection device 101 is determined to be beyond the first preset acid-base range, it indicates that the cathode end of the electrolysis device 102 is scaled, which may result in reduction of electrolysis efficiency, so as to control the electrolysis device 102 to start up and manufacture a cleaning solution for cleaning the cathode. The preset first acid-base range is preset by a technician and can be set according to specific practical situations and empirical values.
In the event that it is determined that the pH of the water outlet end of the anode of the electrolysis device 102 is outside the first predetermined acid-base range, the electrolysis device 102 is controlled by the processor 105 to start to produce the cleaning solution. Further, the cleaning solution produced by the electrolysis device 102 may be introduced into the solution storage device 103 connected to the anode water outlet end of the electrolysis device 102, and when the volume of the cleaning solution in the solution storage device 103 reaches a preset storage threshold, the water pump 104 is controlled to start, so as to lead out the cleaning solution in the solution storage device 103 to the cathode water outlet end of the electrolysis device 102.
For example, if the pH of the anode effluent end of the electrolysis device 102 is determined to be 7.2 by the pH detection device 101, the first predetermined acid-base range is set to 7.5-8. At this time, it can be confirmed that the pH value of the anode water outlet end of the electrolysis device 102 is beyond the first preset acid-base range, and the electrolysis device 102 can be controlled by the processor 105 to be activated to produce the cleaning solution. Further, the cleaning solution produced by the electrolysis device 102 may be introduced into the solution storage device 103 connected to the anode water outlet end of the electrolysis device 102, and when the volume of the cleaning solution in the solution storage device 103 reaches a preset storage threshold, the water pump 104 is controlled to start, so as to lead the cleaning solution in the solution storage device 103 to the cathode water outlet end of the electrolysis device 102, so as to clean the scale on the cathode water outlet end of the electrolysis device 102.
Wherein the electrolysis apparatus 102 comprises a cathodic electrolysis cell and an anodic electrolysis cell, the electrolysis cell being capable of converting electrical energy into chemical energy. The operating principle is generally the process of causing redox reactions at the cathode and anode ends by passing an electric current through the electrolyte solution or molten electrolyte (electrolyte) in an electrolysis apparatus, which can occur when a direct current voltage is applied to the electrochemical cell. When the power is on, cations in the electrolyte move to the cathode to absorb electrons, and reduction is carried out to generate new substances; the anions in the electrolyte move to the anode, releasing electrons, and oxidizing to generate new substances. The electrolyte is a compound capable of conducting electricity in an aqueous solution or in a molten state. Such as acids, bases, and most salts, and the like.
During electrolysis of the liquid in the electrolysis apparatus 102, e.g. electrolysis of Na 2 SO 4 In the case of a solution, electrolysis of an aqueous solution is substantial. Due to H + Electrons are obtained in a cathode electrolytic cell, and the reaction formula of a cathode electrode is as follows: 2H + +2e - ＝H 2 (gas), H + Is consumed and residual OH - Therefore, the pH value of the cathode water outlet end is alkaline; and due to OH - Electrons are obtained in an anode electrolytic cell, and the reaction formula of an anode electrode is as follows: 4OH - -4e - ＝O 2 (gas) +2H 2 O，OH - Is consumed, remains H + Therefore, the pH value of the anode water outlet end is acidic. Na, the anions and cations in the solution inside the electrolytic cell of the electrolysis apparatus are to move directionally + To be moved directionally to the cathode,
the cathode is generated with sodium hydroxide and the pH value of the cathode is alkaline. The anode generates sulfuric acid, and the pH value of the anode is acidic. Under the condition that the water scale at the cathode water outlet end is alkaline and the solution at the anode water outlet end is acidic, the solution at the anode end of the electrolysis device 102 can be led out to the solution storage device 103, and then the cleaning solution in the solution storage device 103 can be led out to the cathode end of the electrolysis device 102 through the water pump 104, so that the alkaline water scale at the cathode water outlet end can be effectively cleaned through the acidic cleaning solution manufactured by the electrolysis device 102.
Wherein the solution storage device 103 comprises a housing-based base for containing a liquid, and the storage threshold is a volume of liquid that the solution storage device can store when set by a user via the processor. Capacity often refers to the size of the volume of an object, in liters of capacity, and also to the number of units of objects or spaces that can be accommodated. The preset storage threshold of the solution storage device 103 is preset by a technician and can be set according to specific practical situations and empirical values. For example, solution storage device 103 may be a tank for holding a cleaning solution produced by electrolysis device 102.
The water pump 104 is a machine that delivers or pressurizes a liquid. The water pump transfers mechanical energy of the prime mover or other external energy to the liquid, primarily for transporting the liquid. Specifically, the water pump 104 may be controlled by the processor 105 to be activated to draw the cleaning solution from the solution storage device 103 and deliver the cleaning solution to the cathode end of the electrolysis device 102.
Fig. 2 is a schematic structural diagram of another household appliance electrode cleaning device according to an embodiment of the invention. As shown in fig. 2, in one embodiment, there is provided a household electrical appliance electrode cleaning apparatus, comprising an alkalinity-acidity detection device 201, an electrolysis device 202, a solution storage device 203, a water pump 204, a first valve 21, a second valve 22, a third valve 23, and a processor 205, wherein:
a first valve 21, wherein a first end of the first valve 21 is connected with a water inlet end of the electrolysis equipment 202, and a second end of the first valve 21 is connected with a medium water inlet end;
a second valve 22, wherein a first end of the second valve 22 is connected with the water inlet end of the electrolysis device 202, and a second end is connected with the medium water inlet end;
a third valve 23, wherein a first end of the third valve 23 is connected with the anode water outlet end of the electrolysis device 202, and a second end is connected with the solution storage device 203; and
a processor 205 configured to: under the condition that the pH value determined by the pH value detection device 201 exceeds a preset pH range, controlling the first valve 21, the second valve 22 and the third valve 23 to be opened so as to store the cleaning solution into the solution storage device through the third valve 23; and controlling the first valve 21 and the third valve 23 to be closed and controlling the second valve 22 to be kept in an open state when the solution amount of the cleaning solution in the solution storage device reaches a preset storage threshold value.
The first valve 21 is used for controlling the communication between the medium inlet end and the electrolysis device 202, and the second valve 22 is also used for controlling the communication between the medium inlet end and the electrolysis device 202. The electrolysis apparatus 202 generally comprises a cathodic electrolysis cell and an anodic electrolysis cell. In this embodiment, the first valve 21 is used for controlling the communication between the medium inlet and the anode electrolyzer of the electrolysis device 102, the second valve 22 is used for controlling the communication between the medium inlet and the cathode electrolyzer of the electrolysis device 102, and the third valve 23 is used for controlling the communication between the anode electrolyzer outlet of the electrolysis device 102 and the solution storage device 203.
Firstly, the pH value of the solution at the anode water outlet end of the electrolysis equipment 202 is determined by the pH value detection equipment 201, and under the condition that the pH value detected by the pH value detection equipment 201 exceeds the preset acid-base range, the cathode end of the electrolysis equipment is indicated to be scaled, so that the electrolysis efficiency is reduced. The processor 205 may then control the start-up of the electrolysis apparatus 202 to produce a cleaning solution for cleaning the cathode side of the electrolysis apparatus 205. Specifically, the processor 205 controls the electrolytic medium to enter from the medium inlet port and controls the first valve 21, the second valve 22 and the third valve 23 to be opened simultaneously, so that the electrolytic medium is introduced into the cathode port of the electrolysis device 202 through the first valve 21 and into the anode port of the electrolysis device 202 through the second valve 22, respectively. At this time, the processor 205 controls the electrolysis device 202 to start producing the cleaning solution, and the produced cleaning solution is introduced into the solution storage device 203 through the opened third valve 23. For example, the electrolytic medium may be tap water. The processor 205 may control the tap water to enter from the medium inlet and control the first valve 21, the second valve 22 and the third valve 23 to open simultaneously, so that the tap water is introduced into the cathode end of the electrolysis apparatus 202 through the first valve 21 and into the anode end of the electrolysis apparatus 202 through the second valve 22, respectively. At this time, the processor 205 controls the electrolysis device 202 to start producing the cleaning solution, and the produced cleaning solution is introduced into the solution storage device 203 through the opened third valve 23.
In the case where the volume of the cleaning solution in the solution storage device 203 reaches a preset storage threshold, the electrolysis device 202 may be controlled by the processor 205 through the control circuit to stop the production of the cleaning solution. Specifically, the processor 205 controls the first valve 21 and the third valve 23 to be closed, and the first valve 21 is closed, so that the anode water inlet passage of the electrolysis device 202 is closed. The third valve 23 is closed so that the passage between the anode outlet of the electrolysis device 202 and the solution storage device 203 is closed. And the second valve 22 is controlled to keep an open state, and the second valve 22 opens a passage between the medium water inlet end and the cathode electrolytic cell of the electrolysis device 203 to be kept open, so that the next step of cleaning the cathode water outlet end of the electrolysis device 203 is facilitated.

The second valve 32 is used for controlling the communication between the medium inlet and the electrolysis device 302, and the fourth valve 34 is used for controlling the communication between the solution storage device 303 and the water pump 304.

Specifically, the pH (pH value) of the aqueous solution at the anode end of the electrolysis device 302 may be first determined by the pH detection device 301.

When the fifth valve 45 is in a closed state, the solution at the cathode water outlet end can be directly discharged out of the electrode cleaning device of the household electrical appliance; when the fifth valve 45 is in an open state, the second valve 42, the fourth valve 44 and the fifth valve 45 are simultaneously in an open state, and at this time, the cleaning solution in the solution storage device 403 is led out and pressurized by the water pump 404, so as to form a circulation path to repeatedly clean the cathode water outlet end of the electrolysis device 402.
In the case where the second valve 42, the fourth valve 44 and the fifth valve 45 are simultaneously opened, this circulation path of "the solution storage means 403-the water pump 404-the electrolysis means 402-the solution storage means 403" is formed, so that the cleaning solution is repeatedly cleaned in the above-described means for cleaning the electrolysis means. In the repeated cleaning process, a user can set a preset cleaning time through the processor, and the preset cleaning time is the cleaning time preset by the user and can be set according to specific actual conditions and experience values.
After the cathode outlet end of the electrolysis device 402 is cleaned, the processor 405 controls the fifth valve 45 to close through the control circuit. The circulation path is disconnected after the fifth valve 45 is closed, and it is determined that the cleaning is completed.
In one embodiment, when storing the cleaning solution to the solution storage device, the processor is further configured to: reducing the flow rate of the solution at the water inlet end of the electrolysis equipment; or to increase the current or voltage of the electrolysis apparatus.
The cleaning solution produced by the electrolysis equipment cleans the cathode water outlet end of the electrolysis equipment, and in the electrolysis process, the cathode water outlet end is subjected to alkaline scaling, and the cathode water outlet end needs to be cleaned by the acidic cleaning solution.
For example, if the user presets the standard of the cleaning solution to be that the pH value is less than 6.5, the pH value of the cleaning solution manufactured by the electrolysis equipment is reduced by reducing the flow rate of the solution at the water inlet end of the electrolysis equipment, so that the pH value of the solution entering the solution storage equipment meets the standard of the cleaning solution; or by increasing the current or voltage of the electrolysis equipment, the electrolysis efficiency is improved. Under the condition of high current or voltage, the pH value of the solution entering the solution storage device in the electrolysis device meets the standard of the cleaning solution.
Specifically, the solution acidity in the anode electrolytic cell can be improved by increasing the flow rate of the anode water inlet end of the electrolysis equipment, so that the cleaning effect of the cleaning solution on the cathode water inlet end is improved.

As shown in fig. 5, in one embodiment, there is provided a household electrical appliance electrode cleaning apparatus, comprising a ph detection device 501, an electrolysis device 502, a solution storage device 503, a water pump 504, a cleaning core water inlet valve 51, a cleaning core 52, and a processor 505, wherein:
a cleaning core water inlet valve 51, wherein the first end of the cleaning core water inlet valve 51 is connected with the medium water inlet end, and the second end is connected with the cleaning core 52;
a cleaning core 52, wherein a first end of the cleaning core 52 is connected with the cleaning core water inlet valve 51, and a second end is connected with the water inlet end of the electrolysis equipment 502 for generating a cleaning solution;
a processor 505 configured to: and under the condition that the pH value obtained by the pH value detection equipment 501 exceeds a first preset pH range, controlling the cleaning core water inlet valve 51 to be opened so as to clean the cathode water outlet end of the electrolysis equipment 502 by the cleaning solution generated by the cleaning core 52.
The cleaning core water inlet valve 51 is used for controlling the passage condition between the medium water inlet end and the cleaning core 52, and the cleaning core 52 is used for generating a cleaning solution, in this embodiment, the pH (pH value) value of the anode end water solution is determined by the pH value detection device 501. Specifically, in the case that the electrolysis apparatus 502 is operating normally and the water inlet flow rate is maintained at a normal level, the ph value of the water outlet at the anode end of the electrolysis apparatus is usually lower than the preset first ph range, which indicates that the water outlet at the cathode end of the electrolysis apparatus 502 can operate normally. If the pH value detected by the pH value detection device 501 exceeds the first preset acid-base range, it indicates that the cathode end of the electrolysis device 502 is scaled, which may result in a decrease in electrolysis efficiency, so that the processor 505 controls the cleaning core water inlet valve 51 to be opened through the control circuit, and manufactures a cleaning solution for cleaning the cathode through the cleaning core 52.
The cleaning solution is then conducted from the anode outlet end of the electrolysis device 502 to the solution storage device 503. In the case that the solution amount of the cleaning solution in the solution storage device 503 reaches a preset storage threshold, at this time, the solution amount has reached the cleaning requirement, and the processor 505 controls the water pump 504 to be turned on through the control circuit. The cleaning solution in the solution storage device 503 is led out by the water pump 504, and the led-out cleaning solution is led into the electrolysis device 502 through the cleaning core water inlet valve 51 and the cleaning core 52, so as to clean the cathode water outlet end of the electrolysis device 502.
The preset first acid-base range is preset by a technician and can be set according to specific practical situations and empirical values.
The cleaning core 52 can separate solid particles in the electrolyte flowing in through the medium water inlet section, or make different material components fully contact, so as to accelerate the reaction time, and can protect the normal work of the electrolysis equipment 502 and the inside cleanness of the electrolysis equipment by a method of removing impurities. The cleaning core 52 can make the liquid (including oil, water, etc.) polluted to meet the standard required by users in production and life after passing through the cleaning core, that is, the cleaning core 52 can make the liquid passing through the interior of the cleaning core 52 reach the cleanness degree preset by users.
For example, setting the first predetermined acid-base range to 7.5-8, determining the pH value of the anode effluent end to be 7.2, and then determining that the pH value exceeds the first predetermined acid-base range, and further controlling the cleaning core water inlet valve 51 to open, so as to produce the cleaning solution through the cleaning core 52.
In one embodiment, the wash core is at least one of a soluble acidic species and an acidic aqueous solution; the pH value of the cleaning solution generated by cleaning the core is 1-3.
In the above-described embodiment of the invention, the cleaning core 52 is provided as an acid filter core. During electrolysis of the liquid in the electrolysis module 502, e.g. electrolysis of Na 2 SO 4 In the case of a solution, electrolysis of an aqueous solution is substantial. Due to H + Electrons are obtained in a cathode electrolytic cell, and the reaction formula of a cathode electrode is as follows: 2H + +2e - ＝H 2 (gas), H + Is consumed and residual OH - Therefore, the pH value of the cathode water outlet end is alkaline; and due to OH - Electrons are obtained in an anode electrolytic cell, and the reaction formula of an anode electrode is as follows: 4OH - -4e - ＝O 2 (gas) +2H 2 O，OH - Is consumed, H remains + So that the pH value of the water outlet end of the anode is acidic. Na, the anions and cations in the solution inside the electrolytic cell of the electrolysis apparatus are to move directionally + To be moved directionally to the cathode,
the cathode is generated with sodium hydroxide and the pH value of the cathode is alkaline. The anode generates sulfuric acid, and the pH value of the anode is acidic.
Therefore, the soluble acidic substance and the acidic aqueous solution are provided inside the cleaning core 52 to achieve the same acidic cleaning effect as the anode end aqueous solution. For example, citric acid can be arranged inside the cleaning core, wherein the formula of the Citric Acid (CA) is C 6 H 8 O 7 It is an important organic acid, colorless crystal, odorless, strong sour taste, easy to dissolve in water, and is a natural preservative and food additive. The citric acid has little corrosion to metal and is a safe cleaning agent, so the cleaning solution generated after the citric acid is arranged in the cleaning core does not have important influence on the electrolysis equipment. Since citric acid does not contain chloride ions, it does not cause stress corrosion of equipment, and it can complex ferric ions and weaken the promoting effect of ferric ions on corrosion. Citric acid can dissolve ferric oxide and cupric oxide to generate complex of ferric citrate and copper, and ferrous ammonium citrate and ferric citrate complex with high solubility can be generated if ammoniated citric acid solution is adopted, so that the product is clearThe cleaning effect is very good, the citric acid mainly removes rust, so the citric acid is mainly used for cleaning newly-built boilers, the citric acid is mixed with sulfamic acid, glycolic acid or formic acid and can be used for cleaning calcium magnesium scale and rust in the boilers, and the citric acid is mixed with Ethylene Diamine Tetraacetic Acid (EDTA) and can be used for cleaning superheaters.
The pH value describes the degree of acidity and alkalinity of an aqueous solution, and is expressed by pH. Under thermodynamic standard conditions, an aqueous solution having a pH of 7 is neutral, an aqueous solution having a pH of less than 7 is acidic, and an aqueous solution having a pH of more than 7 is basic.
The pH range is between 0 and 14, the method is only suitable for dilute solution, and the pH value of the solution with the hydrogen ion concentration or the hydroxyl ion concentration of more than 1mol/L is directly expressed by concentration. When the quantity of the acid ions is constant, the water inlet quantity is controlled to be reduced so as to realize that the pH value of the cleaning solution generated by cleaning the core is 1-3.

and the second detection device 62 is connected with the anode water outlet end of the electrolysis device 601 and is used for detecting the pH value of the liquid at the anode water outlet end of the electrolysis device.
The first detection device 61 detects the pH value of the cleaning solution led out of the water pump, and sends out a reminding signal when the cleaning solution is neutral or alkaline; the second detection device 62 detects the pH value of the liquid at the anode water outlet end of the electrolysis device 601, determines the pH value (pH value) of the aqueous solution at the anode end, and when the electrolysis device 601 normally operates and the water inlet flow rate is maintained at a normal level, the pH value of the water outlet at the anode end is usually lower than a preset first pH range, which indicates that the water outlet at the cathode end of the electrolysis device 601 can normally operate. If the second detection device 62 determines that the detected pH value is beyond the first preset acid-base range, it indicates that the cathode end of the electrolysis device 601 is fouled, which may result in a decrease in electrolysis efficiency. The processor 604 thus controls the activation of the electrolysis device 604 via the control circuit to produce a cleaning solution for cleaning the cathode side of the electrolysis device 601.

In electrolytic processes, e.g. electrolysis of Na 2 SO 4 In the case of a solution, electrolysis of an aqueous solution is substantial. Due to H + Electrons are obtained in a cathode electrolytic cell, and the reaction formula of a cathode electrode is as follows: 2H + +2e - ＝H 2 (gas), H + Is consumed and residual OH - Therefore, the pH value of the cathode water outlet end is alkaline; and due to OH - Electrons are obtained in an anode electrolytic cell, and the reaction formula of an anode electrode is as follows: 4OH - -4e - ＝O 2 (gas) +2H 2 O，OH - Is consumed, H remains + So that the pH value of the water outlet end of the anode is acidic. Na, the anions and cations in the solution inside the electrolytic cell of the electrolysis apparatus are to move directionally + To be moved directionally to the cathode,
