Description

Technical Field

[0001] The present invention relates to the technical field of descaling, and in particular to a scale treatment method, a scale treatment device and a computer device. Background Art

[0002] During the heating process of the electric water heater, the calcium ions and magnesium ions in the water will form substances that are difficult to dissolve in water, such as calcium carbonate, magnesium carbonate, and magnesium hydroxide. After long-term use, these substances will accumulate on the surface of the electric heating tube to form scale. Compared with other parts inside the inner tank, the surface of the electric heating tube is relatively rough, which is easy to adsorb scale. The scale on the surface of the electric heating tube often leads to a decrease in the thermal conductivity of the electric heating tube, resulting in waste of electric energy, a deterioration in the thermal conductivity of the electric heating tube, resulting in excessive temperature and surface cracking and damage, easy breeding of bacteria, and abnormal heating noise. Therefore, how to remove the scale on the surface of the electric heating tube is an important issue that needs to be considered when developing electric water heaters.

[0003] In the relevant descaling schemes for electric water heaters, existing electric water heaters usually use electrolysis to descaling, and the descaling effect is difficult to control.

[0049] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0050] In conjunction with the application scenarios on which the execution of the scale treatment method depends, the application scenarios are described here.

[0051] During the heating process of the electric water heater, the calcium ions and magnesium ions in the water will form substances that are difficult to dissolve in water, such as calcium carbonate, magnesium carbonate, and magnesium hydroxide. After long-term use, these substances will accumulate on the surface of the electric heating tube to form scale. Compared with other parts inside the inner tank, the surface of the electric heating tube is relatively rough, which is easy to adsorb scale. The scale on the surface of the electric heating tube often leads to a decrease in the thermal conductivity of the electric heating tube, resulting in waste of electric energy, a deterioration in the thermal conductivity of the electric heating tube, resulting in excessive temperature and surface cracking and damage, easy breeding of bacteria, and abnormal heating noise. Therefore, how to remove the scale on the surface of the electric heating tube is an important issue that needs to be considered when developing electric water heaters.

[0052] Based on this, an embodiment of the present invention provides a scale treatment method, which can first detect the scale thickness value of the electric heating tube in the water heater, and when the scale thickness value meets the treatment condition, determine the descaling time based on the scale thickness value and the descaling voltage. Then, the descaling mode can be turned on, and the electric heating tube can be descaled based on the descaling time, while ensuring the descaling effect without affecting the service life of the water heater.

[0053] According to an embodiment of the present invention, an embodiment of a scale treatment method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0054] In this embodiment, a scale treatment method is provided, which can be used in the above-mentioned hot water device, for example, an electric water heater. Figure 1 is a flow chart of a scale treatment method according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0055] Step S101, detecting the scale thickness value of the electric heating tube in the hot water device.

[0056] In an embodiment of the present invention, the hot water device may be an electric water heater, in which a detection circuit may be provided to detect the thickness of scale attached to the surface of the electric heating tube. Since the scale attached to the surface of the electric heating tube may affect the conductivity of the electric heating tube, the thickness of the scale on the surface of the electric heating tube may be determined based on the current in the detection circuit.

[0057] Step S102: when the scale thickness value meets the processing condition, the descaling time is determined based on the scale thickness value and the descaling voltage.

[0058] In an embodiment of the present invention, the processing conditions may include a thickness threshold. Considering that frequent descaling will affect the use of the water heating device, when the determined scale thickness value exceeds the thickness threshold, it can be determined that the scale thickness value meets the processing conditions, and the descaling time can be determined based on the scale thickness value and the pre-set descaling voltage, thereby achieving precise descaling to avoid the descaling time being too long and affecting the service life of the water heating device.

[0059] It should be understood that, considering that the descaling voltages corresponding to different types of water heaters may be different, they can be set specifically according to the types of water heaters and actual usage scenarios, and the present disclosure does not specifically limit the setting method of the descaling voltage. Since the descaling efficiencies corresponding to different descaling voltages are different, the descaling time corresponding to the same scale thickness value under different descaling voltages is also different. Therefore, the association information between the scale thickness value and the descaling voltage and the descaling time can be established in advance, so that when the scale thickness value meets the processing conditions, the descaling time corresponding to the current scale thickness value and the descaling voltage is determined based on the association information.

[0060] Step S103, start the descaling mode, and descaling the electric heating tube based on the descaling time.

[0061] In an embodiment of the present invention, a descaling circuit may be provided in the electric water heater, and the descaling circuit may be used for electrolyzing water for descaling. By utilizing the descaling circuit, the electric heating tube is descaled based on the descaling time and the descaling voltage.

[0062] Specifically, during the electrolytic descaling process, the cathode of the descaling circuit generates hydrogen gas due to the hydrogen ions gaining electrons, which causes the pH value of the cathode area to increase and become alkaline. The specific reaction can be expressed as: 4H++4e - =2H2↑. On the contrary, the anode end is the opposite. Hydroxyl ions or water molecules lose electrons to generate oxygen, which causes the pH value of the anode area to decrease and become acidic. The specific reaction can be expressed as: 4OH--4e - =2H2O+O2↑.

[0063] Therefore, the electric heating tube can be set as the anode, so that the acidic solution in the anode area reacts with the scale such as calcium carbonate and magnesium carbonate on the surface of the electric heating tube to remove the scale. It should be understood that since the anode end metal is very easy to lose electrons and corrode during the electrolysis process, it is necessary to control the descaling mode within the above descaling time to avoid affecting the service life of the water heater. In addition, the electric heating tube can be designed by using highly corrosion-resistant materials or corrosion-resistant materials with plating to further extend the service life of the water heater.

[0064] It can be seen from the above description that in the embodiment of the present invention, the scale thickness value of the electric heating tube in the water heater can be detected first, and when the scale thickness value meets the processing conditions, the descaling time can be determined based on the scale thickness value and the descaling voltage. Then, the descaling mode can be turned on, and the electric heating tube can be descaled based on the descaling time, so as to accurately evaluate the scale thickness covered on the surface of the electric heating tube, so as to accurately determine the descaling time based on the scale thickness, and ensure the descaling effect without affecting the service life of the water heater.

[0065] In this embodiment, another scale treatment method is provided, which can be used in the above-mentioned hot water device, such as an electric water heater, etc. Figure 3 is a flow chart of a scale treatment method according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:

[0066] Step S301, detecting the scale thickness value of the electric heating tube in the hot water device.

[0067] Specifically, the above step S301 includes:

[0068] Step S3011, start the detection mode, and build a detection circuit based on the electrode rod and the electric heating tube of the water heater in the detection mode.

[0069] Step S3012, operating the detection circuit based on the first voltage, and the current of the detection circuit flows from the electrode rod to the electric heating tube.

[0070] Step S3013, detecting the current value in the above detection circuit, and determining the scale thickness value corresponding to the current value.

[0071] In one embodiment, if Figure 2 The figure shows a schematic diagram of the internal structure of the electric water heater, wherein the electric water heater includes an electric control board, electrode rods, an inner tank and electric heating tubes, wherein all components except the electric control board are insulated from each other.

[0072] Specifically, Figure 4The schematic diagram of the detection circuit is shown in which the detection circuit is operated according to the detection circuit, wherein the detection circuit is a DC circuit. In the detection mode, the electrode rod is connected to the positive electrode of the DC power supply through the electric control board, and the outer metal layer of the electric heating tube is connected to the negative electrode of the DC power supply to construct a detection circuit. The current in the detection circuit flows from the electrode rod to the electric heating tube. The present invention realizes a lower-cost descaling strategy by improving the design of the existing structure in the water heater.

[0073] It can be understood that the negative pole of the DC power supply can be connected to the ground terminal of the electric control board, and the outer metal layer of the electric heating tube can be grounded to achieve the connection of the outer metal layer of the electric heating tube to the negative pole of the DC power supply.

[0074] After adding water into the electric water heater, the detection circuit formed between the electrode rod and the electric heating tube constitutes a pathway. Since scale attached to the surface of the electric heating tube will affect the conductivity of the electric heating tube, the thickness of the scale on the surface of the electric heating tube can be determined based on the current in the detection circuit.

[0075] It should be understood that the above-mentioned electrode rod (electronic anode), inner tank and electric heating tube are all relatively common designs in water heaters. Specifically, the electric heating tube is the core component of the electric water heater, which is mainly responsible for converting electrical energy into thermal energy to heat water. The inner tank is a container for storing water in the electric water heater, usually made of stainless steel, with good thermal insulation performance and corrosion resistance.

[0076] In an embodiment of the present invention, when the hot water device is the above-mentioned electric water heater, the above-mentioned first voltage can be 3.2V. It should be understood that the first voltage can be set according to the specific type of the hot water device, which is subject to what can be achieved, and the present invention does not limit it.

[0077] It is understandable that the electrode rod is used to protect the inner container, and when the electrode rod is used for protection, the inner container will be grounded. Figure 4 As shown, while the electrode rod is set as the positive pole of the power supply and the electric heating tube is set as the negative pole of the power supply, the grounding of the inner tank can be disconnected and set to be suspended, so as to avoid shunting caused by the grounding of the inner tank and affect the accuracy of the detection.

[0078] It is understandable that the existing electric heating pipe includes a central heating wire, an outer metal layer wrapped outside, and an insulating layer between the two. When the water heater is in heating mode, the heating wire can be used to connect to AC (neutral wire, live wire). When powered on, the heating wire generates heat to heat the water. When the water heater is in detection mode, the outer metal layer of the electric heating pipe can be grounded because there is an insulating layer between the outer metal layer and the heating wire. Therefore, the grounding of the outer metal layer will not affect the internal heating wire.

[0079] When the scale thickness value is detected based on the detection circuit, the current value in the detection circuit can be detected, and the scale thickness value corresponding to the current value can be determined by looking up a table.

[0080] In the embodiment of the present invention, a lookup table between current values ​​and scale thickness values ​​may be pre-established, and a lookup may be performed based on the lookup table to obtain the scale thickness value corresponding to the current value in the current detection circuit.

[0081] Specifically, when determining the above-mentioned lookup table, first, a brand new electric heating tube can be placed in high-hardness water for heating, and then the water can be changed after the heating is completed. Since high-hardness water will obviously scale after heating, the diameter of the electric heating tube needs to be measured every two heatings, and the original diameter of the electric heating tube is subtracted to obtain the scale thickness until the calibration is completed. A high-magnification electron microscope can be used for the tube diameter measurement. After measuring the scale thickness value of the current electric heating tube, the current value output by the electric heating tube can be correlated with the scale thickness value to obtain a correlation relationship, and then the lookup table can be determined based on the correlation relationship.

[0082] Based on this, after detecting the current value in the detection circuit, a lookup table can be used to determine the scale thickness value corresponding to the current value, thereby eliminating the need to calculate the scale thickness value corresponding to the current value in real time, reducing the computing power required for the water heating device.

[0083] Step S302: when the scale thickness value meets the processing condition, determine the descaling time based on the scale thickness value and the descaling voltage.

[0084] When determining the descaling time, the descaling time associated with the current scale thickness value of the hot water pipe can be obtained by looking up a table.

[0085] Step S303, start the descaling mode, and descaling the electric heating tube based on the descaling time.

[0086] In some optional implementations, when the descaling mode is turned on, the above step S303 further includes:

[0087] Step S3031, switching to the descaling mode, constructing a descaling circuit based on the electrode rod and the electric heating tube.

[0088] Step S3032, operating the descaling circuit based on the second voltage, the current of the descaling circuit flows from the electric heating tube to the electrode rod, and the second voltage is used as the descaling voltage.

[0089] In the embodiment of the present invention, the polarities of the electrode rod and the electric heating tube in the descaling circuit and the detection circuit are different. After the descaling mode is turned on, the descaling circuit operates according to the polarity of the descaling circuit, and the second voltage is used as the descaling voltage. The present invention can control the switching of the detection circuit and the descaling circuit through the electric control board. Therefore, the present invention realizes a lower-cost descaling strategy by improving the design in the existing structure of the water heater.

[0090] In other examples, the detection circuit and the descaling circuit may be separate circuits. It is understandable that the second voltage may be the same as or different from the first voltage. It is understandable that the electric control board is connected to alternating current, and a direct current power supply is obtained after rectification and voltage reduction. Among them, when the second voltage is the same as the first voltage, when switching, one way may be that the contact points of the electrode rod, the electric heating tube and the direct current power supply remain unchanged, and the polarity of the electrode rod and the electric heating tube is changed by adjusting the peripheral circuit of the direct current power supply; another way may be that the contact points of the electrode rod, the electric heating tube and the direct current power supply are changed by switching the switch, thereby changing the polarity of the electrode rod and the electric heating tube. When the second voltage is different from the first voltage, a direct current power supply of different voltages is obtained after rectification and voltage reduction, and different direct current power supplies are switched to connect by switching the switch, so as to complete the switching of the detection circuit and the descaling circuit.

[0091] like Figure 5 Shown is a schematic diagram of the descaling circuit operating according to the descaling circuit, wherein, in the descaling mode, the outer metal layer of the electric heating tube in the descaling circuit can be connected to the positive electrode of the DC power supply through the electronic control board, and the electrode rod can be grounded or connected to the negative electrode of the DC power supply to construct the descaling circuit.

[0092] In an embodiment of the present invention, when the hot water device is the above-mentioned electric water heater, the above-mentioned second voltage can be 12V. It should be understood that the second voltage can be set according to the specific type of the hot water device, which is subject to what can be achieved, and the present invention does not limit it.

[0093] Depend on Figure 5 It can be seen that while setting the electric heating tube as the positive pole of the power supply and the electrode rod as the negative pole of the power supply, the grounding of the inner tank can be disconnected and set to be suspended, so as to avoid shunting caused by the grounding of the inner tank and affect the descaling effect.

[0094] It should be understood that after the descaling circuit is turned on, the electric heating tube acts as the anode end of the electrolysis reaction, and the pH value of the solution in the electric heating tube area decreases to a weakly acidic state, reacting with scale such as calcium carbonate and magnesium carbonate on the surface of the electric heating tube, thereby achieving a descaling effect.

[0095] In addition, the water heater can also support the operation of the electronic anode mode to protect the inner tank, such as Figure 6It is a schematic diagram showing the operation of the descaling circuit according to the electronic anode circuit, wherein in the electronic anode mode, the electrode rod in the descaling circuit can be connected to the positive pole of the DC power supply through the control of the electronic control board, and the inner tank can be grounded or connected to the negative pole of the DC power supply, and the heating rod can be set to be suspended.

[0096] In the embodiment of the present invention, the descaling mode can be operated by switching the polarity of the descaling circuit, thereby achieving descaling without changing the internal structure of the water heater, having low manufacturing cost, strong compatibility with multiple series of products, and having little impact on the inner tank of the water heater, thereby reducing the impact on the overall service life of the water heater.

[0097] In some optional implementations, the above step S302 includes:

[0098] Determine the descaling time corresponding to the scale thickness value by looking up the table.

[0099] In an embodiment of the present invention, the descaling time may be a descaling time for dissolving the scale thickness value on the surface of the electric heating pipe to a preset thickness value in the descaling mode, wherein the preset thickness value d>0, and d may be set to a value slightly greater than 0. Here, the preset thickness value is not set to 0 to effectively avoid damage to the coating on the surface of the electric heating pipe caused by excessive cleaning of the scale. Specifically, when determining the descaling time, the descaling time associated with the scale thickness value of the current hot water pipe may be obtained by querying the above-mentioned lookup table.

[0100] It should be understood that when determining the above-mentioned lookup table, the scale thickness value and the corresponding descaling time can also be calibrated. Specifically, multiple electric heating tubes with different scale thickness values ​​of scale attached to the surface can be taken, and the descaling mode can be run after the target circuit is installed, and the descaling time for the scale on the surface of the electric heating tube to be dissolved to a preset value under the second voltage is recorded, so that the correlation between the current scale thickness value and the descaling time is stored in the lookup table.

[0101] In an embodiment of the present invention, the correlation between different scale thickness values ​​and the corresponding descaling times can be stored in a lookup table, so that the descaling time corresponding to the current scale thickness value of the water heater can be determined by looking up the table, so as to achieve precise control of the descaling time, while ensuring the descaling effect and reducing the impact on the life of the water heater.

[0102] In some optional implementations, before detecting the scale thickness value of the electric heating pipe in the hot water device, the method further includes:

[0103] Based on the start signal, the hot water device is controlled to enter a detection mode to detect the scale thickness value of the electric heating tube.

[0104] In an embodiment of the present invention, based on the start signal, controlling the water heater to enter the detection mode to detect the scale thickness value of the electric heating tube may include the following implementation methods:

[0105] Method 1: The user initiates a detection request to start the detection mode.

[0106] In an embodiment of the present invention, a user can initiate a detection request according to his or her own detection needs. Specifically, a detection button can be set in the water heater, and the user can generate a start request for the detection mode by triggering the detection button. After receiving the start request, the control unit can detect whether the water heater meets the start condition. For example, the start condition can be set to the heating mode. If it is detected that the water heater is not in the heating mode, the detection mode is started; if not, the detection mode is started after the heating mode of the water heater ends.

[0107] Method 2: The hot water device automatically starts the detection mode.

[0108] In an embodiment of the present invention, the water heater can be controlled to enter a detection mode according to a preset detection cycle. When the preset detection cycle is reached, a start signal can be generated to control the water heater to enter a detection mode when the water heater meets the start condition. Specifically, the preset detection cycle can be one week, one month, etc. It should be understood that the user can set the preset detection cycle according to their own usage requirements, and the present disclosure does not specifically limit the time interval of the preset detection cycle.

[0109] In addition, the start of the detection mode can also be conditionally triggered. When the state of the water heater meets the trigger condition, a start signal is generated to control the water heater to enter the detection mode. Specifically, the trigger condition can be set to the start temperature in the non-heating mode. For example, if the start temperature is 72°C, when the water heater is in the non-heating mode, if the water temperature reaches 72°C, a start signal is generated.

[0110] In the embodiment of the present invention, the water heater can be controlled to enter the detection mode through a variety of triggering modes, thereby meeting the diverse usage requirements of users in different usage environments and improving the user experience.

[0111] In summary, in the embodiment of the present invention, the scale thickness value of the electric heating tube in the water heater can be detected first, and when the scale thickness value meets the processing conditions, the descaling time can be determined based on the scale thickness value and the descaling voltage. Then, the descaling mode can be turned on, and the electric heating tube can be descaled based on the descaling time, so as to accurately evaluate the scale thickness covered on the surface of the electric heating tube, so as to accurately determine the descaling time based on the scale thickness, and ensure the descaling effect without affecting the service life of the water heater.

[0112] In this embodiment, a scale treatment device is also provided, which is used to implement the above-mentioned embodiments and preferred embodiments, and the descriptions that have been made will not be repeated. As used below, the term "module" can be a combination of software and / or hardware that implements a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceivable.
