Description

Water heater control method and device capable of energy saving and anti-scaling

The invention relates to energy saving of two types of water heaters, such as liquefied gas or natural gas water heater (collectively referred to as gas water heater) and instant heat or heat storage electric water heater (the above two electric water heaters are collectively referred to as electric water heaters) And a control method and device for preventing scale formation, which provides a hot water user to stop the energy supply of the water heater by operating the switch a little before the end, and let the hot water continue to flow out to save energy, and can effectively prevent Scale is generated by the inventor of the water heater.

Whether it is a gas water heater or an electric water heater, the hot water valve is used to end the use of hot water, but this leaves a lot of hot water in the water heater and the pipeline, and gradually cools, so academically said that it is not used. The hot water on the water is ineffective hot water. When using hot water, when the hot water valve is opened, the water temperature of the effluent is gradually increased. It takes a minute or two to reach the high point, and usually the hot water is about to end. When the water temperature at the outlet of the water heater is also the highest, such high temperature hot water can not be used, it is a pity, especially in the case of gas water heaters, when the hot water valve is closed, it will be delayed by 3 to 5 seconds. The length of the delay time depends on the length of the pipeline. Until the electronic controller equipped with the water heater detects that the water pressure of the water tray is insufficient, the output signal informs the main furnace that the solenoid valve is closed and the flame is extinguished. At this time, the hot water inside the water heater has reached High temperature and no flow, but still accept this amount After 3 to 5 seconds of heating, the water temperature will rise even higher. Not only wastes energy, but also makes the water heater more easily accumulate scale, which also causes heat exchange efficiency to become worse and worse, and affects the service life and safety of the water heater.

In view of the above problems, the present invention is designed to be a water heater control method and device capable of saving energy and preventing scale formation, and can be applied to a gas water heater and an electric water heater to control the energy supply thereof and let the user end the use of hot water. Before, apply the control method and device first, and suspend the supply of gas, natural gas or electricity from about 50 seconds to more than one minute before the above-mentioned so-called invalid hot water can continue to flow out for use, becoming effective hot water. The amount of hot water depends on the capacity of the equipment and the length of the pipeline. For example, in the case of a general household gas water heater, there is 12 liters of hot water per minute, and the water temperature is 21 degrees (the average annual temperature in Taiwan). At 58 degrees, when the hot water valve is closed, the hot water in the water heater and the pipeline is left. The diameter of the general piping is 0.5 inches, and the length is 9 meters (including the shower head pipe), plus the tube. The road is cooled, and it is known from experiments that there is more than 194kcal of heat energy wasted.

In addition, because the general gas water heater is used, after the hot water valve is closed, it takes 3 to 5 seconds to delay, the gas will turn off, and the average heat energy will waste 24kcal. Fortunately! The invention can overcome the problem that each time the gas water heater is included, including the above data, the energy can be saved up to 218 kcal or more, of course, if the water heater is turned on and off multiple times in each bath, then The waste of heat energy will increase dramatically.

At present, there are a total of 23.28 million people, a total of 7.36 million, with an average of 3.16 per household, while gas water heater users account for 69.8%, a total of 5.137 million, of which 38%, that is, 1.952 million households use natural gas. In addition, the above-mentioned per person uses hot water to waste 218kcal of heat energy, and the natural gas calorific value per degree. For 9000kcal, the water heater efficiency is 83.5%, and the carbon emissions per degree of natural gas is 2.09kg. The carbon emissions per year used in the natural gas water heater can be reduced to 136,500 tons: 1.952 million x 3.16 x 365 x 218 / (9000 x 83. 5%) x2.09kg=136500 tons---(A)

The use of liquefied gas accounts for 62% of the users of gas water heaters, which is 3.185 million households, and the calorific value per kilogram of gas is 12062kcal, the water heater efficiency is 83.5%, and the carbon emissions per kilogram of gas is 3.19kg. In gas water heaters, the annual carbon emissions can be reduced by 253,600 tons: (according to liquefied gas LPG per kg = 1.867 liters, carbon emissions 1.753 kg CO2 / liter, that is, 3.27 kg CO2 / kg per kg carbon, but 3.19 kg CO2 / kg) , 3.185 million x 3.16 people x365x218 / (12062x83.5%) x 3.19 = 253,600 tons --- (B)

In addition, it is generally not necessary to wash your hair in the bath at home, or to cut hair and wash your hair in the convenience store. You can't ignore it. According to conservative calculations, the average person in the barber shop or the home washes the head every 18 days, and the length of the pipeline is set. With 4 meters of Lirong store, the invention can be used to achieve energy-saving benefits: 21 million x 365 days / 18 x 175 kcal / (12062 x 83.5%) x 3.19 = 23,600 tons - (C)

In terms of electric water heaters, it accounts for 24.7%, which is 1.818 million. The length of the electric water heater is about 4.3 meters (including the shower head pipe). The heat loss of the water heater and the pipeline can be reduced to 72kcal per degree. The calorific value of the electricity production is 860kcal, the water heater efficiency is calculated at 90%, 1.818 million x3.16 people x365x72kcal/(860x90%)=195.05 million degrees---(D) The power emission coefficient adjusted according to the 100 years of the Republic of China. CO2 emission 0.536kg, then: 195.05 million degrees x 0.536kg / degree = 104.45 million kg = 10.454 million tons --- (E)

In terms of economic benefits, as mentioned earlier, with a small gas water heater, there are 218kcal The above hot water is available for use, such as 1.952 million natural gas users and 20.45 yuan per degree of natural gas. With the invention, it can be saved throughout the year: 1.952 million x 3.16 x 365 x 218 Kcal / (9000 Kcal x 83.5%) x 20.45 = 13.356 billion yuan---(F)

For liquefied gas, if the current government absorption part is 49 yuan per kg, the annual savings can be: 3.185 million x 3.16x365x218 / (12062kcal x 83.5%) x 49 = 3.896 billion yuan --- (G)

21 million x365/18x175kcal/(12062x83.5%) x49=362 million yuan---(H)

The above two gas water heaters (F) 13.356+(G)38.96+(H)3.62 can save a total of 5.593 billion yuan, while the electric water heater can save 195.05 million degrees x 2.8 yuan = 546 million yuan---(J)

Prior to this, we used hot water only once a day to open the hot water valve, without mixing cold water and stopping the hot water in the middle. However, if the hot water is widely used by the Chinese people, there are the following two idioms. Cold water reconciles hot water. This behavior will reduce the water flow in the water heater, and if the gas consumption is not automatically reduced, the water temperature will rise sharply and the hot water flow rate will be slower, so that the heat energy is more easily consumed on the pipeline, even if the water heater There is constant temperature control, and often the hot water temperature is swept away at the upper limit of the set temperature, or it will waste a lot of heat. It is understood that the Chinese people have a shower habit of 83.4%, and almost all showers use cold water to reconcile hot water. Habit, secondly, 86% of bathers will interrupt hot water and wipe soap, wipe the shower gel, wash their hair, wash their face or shave, wash things..., and then do the chores and reopen the hot water valve, so In the use of two or three times of hot water, the waste of heat energy is also considerable. The heat energy wasted by the above two bathing habits will be higher than the previous data. For example, when applying the present invention, as long as one principle is grasped, even if it is switched several times. Valves, hot water before each closing, early suspension of gas supply, which will save considerable waste of energy.

Conservative estimates, with the application of the invention to cold water to adjust hot water, and the habit of switching hot water valves multiple times, can also get more than 35% of the above energy saving (A) + (B) + (C) added: (A)+(B)+(C)=13.65+25.36+2.36=41.37 million tons of carbon emissions, 41.37x (1+35%)=55.849 million tons The carbon emissions that can be reduced per year for gas water heaters.

The electric water heater will consume 20% of the calorific value under the water use habits of the above-mentioned Chinese people, and the invention can be applied to avoid the loss thereof. (E) x1.2 10.45 million tons X1.2 = 124.44 million electric water heaters reduce carbon emissions per year, so gas and electric water heaters can reduce carbon emissions by 554.49 million tons + 125.44 million tons = 687,300 tons, equivalent The amount of carbon absorbed in the 1771 Daan Park (Daan Park has an annual carbon absorption of 386 tons).

In the same way, in the economic benefits of energy saving, the bathing habits of Chinese people will increase by 35% to: (F) + (G) + (H) = 13.35 + 38.96 + 3.62 = 5,593.6 million

5,593.6 million x (1 + 35%) = 7,551.3 million

The electric energy will also increase by 20% due to the bathing habits of the Chinese people: 546 million yuan X1.2 = 655.2 million yuan

Total savings of 7.551 billion + 655.2 million yuan = 8.2 billion yuan.

Therefore, the invention not only reduces the considerable carbon discharge amount, but also saves energy and brings real economic benefits. Even if the water heater is used, it is not only used for bathing and washing, even for brushing, washing, washing dishes, etc. The calorific value of consumption is difficult to calculate, and it is temporarily ignored. The above statistics are quite considerable.

The invention has the functions of energy saving and anti-scaling, and has the effect of reducing the occurrence of gas poisoning accidents, mainly to significantly reduce the amount of gas, and also to open the cycle of using gas, and the user no longer has to rush to use unused. Finished hot water, and rush to use the water heater continuously, so In order to effectively reduce the concentration of indoor gas and carbon dioxide, some households or student dormitories or staff quarters, in order to allow the unused water inside the water heater and the pipeline not to cool down, and then continue to use the water heater one after another, in order to save Energy consumption, but in fact, it takes a few minutes to change hands, and there is no perfect insulation measures inside the water heater and the pipeline. Especially the heat exchanger has good thermal conductivity, and of course it is a good heat dissipation component. The internal hot water quickly dissipates into warm water, and the hot water on the pipeline is easy to dissipate heat, so the benefits obtained are hard to anticipate. Moreover, for poor ventilation, or installed indoors or closed balconies, there is no Forced exhaust gas water heaters are extremely dangerous for users. Especially in Taiwan, users who do not meet the safety and ventilation standards are everywhere, so that when poisoning incidents occur, the invention can be used to alleviate the above. Security concerns.

Figure 7 is a schematic view of the present invention applied to an electric water heater.

The control method, the flow, the function and the device of the present invention are now introduced: Referring to FIG. 1, the present invention mainly consists of a set of high frequency transmitter 1 and high frequency receiver 2 The main control unit is a set of wireless transmitters 3 and wireless receivers 4, as auxiliary units, and the input commands are pressed by the waterproof button 11 and transmitted by the high frequency receiver 2 through the wireless transmission. The contacts 30 and 31 respectively control the water heater and the wireless transmitter 3.

Please refer to Figure 2, the high-frequency transmitter 1, the power supply is a dry battery 10, when the hot water user will end about 50 seconds to more than one minute, press the waterproof button 11, and then detect the circuit 12, then After the button 11 is measured, the command is issued, and the circuit signal having the code is encoded by the code amplifying circuit 13, and then transmitted to the high frequency transmitting circuit 14, generating a high frequency wave, and then transmitting the high frequency wave to the portable antenna 15 through the pocket antenna 15. In the air, the electric wave can penetrate the wall, and the high frequency receiver 2, the antenna 21 receives the electric wave signal, transmits it to the high frequency receiving circuit 22, and then transmits it to the decoding circuit 23 to identify whether the same pairing is performed. Encoding, when the confirmation is correct, the mode selection circuit 24 is used to find the control mode to be followed. The control mode is divided into a jog delay mode 25 and a self-lock mode 26, wherein the jog delay mode is applicable to the gas water heater. The self-locking mode is applicable to the electric water heater. The two modes can be selected by the jump cap 27. If the self-locking mode is selected, the jump cap is connected to 26. If the jog delay mode is selected, the jump cap will be jumped. Connected to 25.

After passing through the mode selection circuit 24, the amplification circuit 28 performs power amplification to drive the output relay 29 to operate, and the normally closed contact 30 of the relay is connected in series with the power supply circuit of the electronic controller equipped with the water heater. Referring to FIG. 1 and FIG. 4, when the relay 29 is actuated, the normally closed contact 30 is changed from the normally closed state to the open state, so that the power supply of the battery 52 is suspended, and the electronic controller 51 equipped with the water heater is Thus losing power.

In Figure 4, the female fire solenoid valve 53, and the female fire nozzle 55, are used for ignition, such as a water-ignited water heater, after the main fire is ignited, the mother fire will automatically turn off, such as non-water ignition In the water heater, the mother fire ignites. When the battery loses power, the electronic controller 51 stops outputting, the mother fire solenoid valve 53, and the main furnace solenoid valve 54, will be closed, the mother fire nozzle 55, and the main furnace fire spray. The nozzle 56, the fire will also be extinguished, and the heat exchanger (commonly known as the water tank) 57, no longer heated, the exhaust port 58, In other words, the carbon dioxide emission is stopped. In order to make the gas stop, the mother fire solenoid valve 53 and the main furnace solenoid valve 54 are kept closed for several seconds to confirm that the gas supply is stopped, and the maintenance is for a few seconds. Delay time, when the delay time is up, the output relay will automatically return. At this time, even if the normally closed contact is closed and the hot water of the water heater and the pipeline continues to flow out, the electronic controller has no output, the mother fire solenoid valve and the main furnace The solenoid valve will not open, so there is no problem with gas leakage.

When the output relay is reset, its normally closed switch 30 changes from the open state to the closed state. At this time, the hot water continues to flow out, but the gas does not leak, there is no danger of poisoning, because only when the normally closed switch is closed, and the gas is closed. The source switch is turned on, the power supply is sufficient, and the electronic controller detects various functions, the electronic ignition function is normal, and then the hot water valve is turned on, the water pressure exceeds the basic pressure, and the ignition can be performed normally, and the organic fire solenoid valve and the main The furnace solenoid valves are operated in sequence, and the gas is sprayed from the mother fire nozzle 55 and the main furnace nozzle 56. If any of the above conditions are not established, the water pressure is insufficient, the power circuit is open, and the electronic controller detects When various functions are not complete, electronic ignition is abnormal, etc., the electronic controller will not drive the female fire solenoid valve 53, and the main furnace solenoid valve 54, both solenoid valves will be closed, so in any case, the control system The operation will not cause the leakage of gas.

In order to enable the user to issue a button command, the user can know that the gas mother solenoid valve 53 and the main furnace solenoid valve 54 are closed, so that the other contact point of the output relay 29 is normally open. Point 31, please refer to Figure 3, as a medium to inform the user, because as described above, the normally closed contact 30, after being turned on, remains open for a few seconds, the gas must be turned off, and the normally open contact 31, which is closed as the relay is actuated, and can be used as the input button of the wireless transmitter 3, and the input detecting circuit 33 of the wireless transmitter 3 detects the normally open contact 31, and changes from the open state to the closed state. At this time, the code amplifying circuit 34 is notified to send a coded and amplified circuit signal, which is converted into a radio wave and outputted through the wireless transmitting circuit 35, and transmitted to the air by the small antenna 36, and then by the wireless receiver 4. After the antenna 41 receives the electric wave, Then, it is processed by the wireless receiving circuit 42 and transmitted to the decoding circuit 43 for decoding identification. If the encoding is the same pairing, the output 埠44 is notified to output, and the diode 45 is illuminated, and the speaker 46 is made. , making a sound or music.

The high-frequency connector 2 and the wireless transmitter 3 can be combined into one body, and the DC power source is used in common, that is, the power supply 32 is used to supply the low-voltage direct current, and the integrated device can be installed in the old device. The inner or lower edge of the water heater is surrounded by the water heater, and the invention can be integrated with the electronic controller equipped with the water heater, and the wireless receiver 4 of the present invention can be combined with the high frequency transmitter 1 described above in the same package. Or separate packaging, such as separate packaging, the user must be able to get a clear sound and light return after the button command is issued, so whenever the user presses the button command, as long as the diode 45 is seen, the light or the speaker 46 is heard. When the sound or music is emitted, the mother fire solenoid valve 53 and the main furnace solenoid valve 54 are both closed, and it can be confirmed that the supply of gas has been suspended. At this time, the hot water continues to flow out, and the cold water also flows into the water heater, the water heater and the tube. The water temperature of the road gradually drops to normal temperature, so there will be no scale formation.

The above two types of high-frequency remote control transmitters, high-frequency receivers, wireless transmitters, and wireless receivers are all wireless transmission devices, and the names are different for convenience.

As for the formation of scale, it is because the tap water contains calcium bicarbonate. Once the water temperature reaches 40 degrees or more, it is decomposed into calcium carbonate, water and carbon dioxide. The calcium carbonate is insoluble in water and will precipitate on the wall when the water is still. Or adhere to the surface of the container and the component to form scale.

The invention not only saves the new water heater from generating scale, but also applies to the old water heater, can clean the internal scale, and automatically removes the scale from the pipe wall, and the principle is that whenever the heat exchanger is After heating, the water temperature is raised to nearly 60 degrees Celsius. After the user closes the gas early, the cold water continues to enter the water tank, and the temperature of the pipe wall gradually decreases until the user feels the water temperature drops and closes the waterway. At this time, the water tank has been closed. The cold water is full, because the expansion coefficient of the scale and the pipe wall is different, and the temperature and the sudden drop of the pipe wall temperature in the water tank, the joint surface of the scale and the pipe wall is natural. The stress is formed, and after that, the water heater is used again and again, the temperature rise and the sudden drop of the pipe wall, so that the stress gradually acts, the scale gradually cracks and breaks off from the pipe wall, and the hot water flows to the water outlet. After the subsequent use of hot water, the scale will completely disappear, and when the scale falls off, the crack is broken and the size is small, which is not enough to block the water pipe. Therefore, the present invention can clean the scale of the old water heater. As a result, the service life can be extended, and the regular cleaning fee for scale can be saved whether it is new or old.

As for the electronic controller equipped with gas water heater, there are two kinds of power supply sources, one of which is battery 52, which is used as DC power supply, as shown in Figure 4, and the other uses commercial power as the power supply source. As shown in FIG. 5, the power supply 59 converts the commercial power into low voltage direct current and supplies it to the electronic controller 51. Therefore, the normally closed contact 30 of the present invention can be serially connected to the AC circuit position or string in front of the power supply 59. The power supply of the electronic controller 51 can be controlled by the position of the DC circuit at the rear.

As shown in FIG. 6, in order to enable the present invention to be applied to a water heater powered by a commercial power supply, the present invention can be manufactured because a power supply is usually built in the internal electronic controller to supply the required low voltage direct current. The plug of the water heater can be accepted as a quick connection by placing the normally closed contact 30 side by side with a conductor 37, and the normally closed contact and the conductor can be respectively connected to the mains, and the normally closed contact and the conductor The other end is connected to the power input terminal of the electronic controller 51, respectively. In this case, the high frequency receiver 2 and the wireless transmitter 3 and the conductor 37 are combined in the same package.

Next, in the case where the present invention is applied to an electric water heater, please refer to FIG. 7. The electric water heater 6 is mainly composed of an electronic controller 61, a power amplifier 62, power relays 63, 64, 65 and 66, and a heating rod 71. The heat exchanger 72 and the like constitute a main component, wherein the output relay 29 from the high frequency receiver 2, the normally closed contact 30, can be connected in series with the previous stage AC power supply circuit or the internal circuit or the rear output circuit of the electronic controller 61. .

For the electric water heater, the mode selection circuit 24 of the high frequency receiver 2 has already selected the self-locking mode 26. When the user presses the waterproof button 11 early before the end of using the hot water, the output relay 29 is actuated, and its normally closed The contact 30 is changed from the closed state to the open state, and the electronic controller 61 is thus interrupted, and the power amplifying device 62 also loses power. The four power relays 63, 64, 65 and 66 are automatically reset, so The corresponding four normally open contacts 67, 68, 69 and 70 are also returned to the original position, and return to the open state from the closed state, thereby causing the heating rod 71 of the water heater to be powered off due to the open circuit of the normally open contact.

While the output relay 29 is actuating, the other contact, that is, the normally open contact 31, is also actuated, so that the wireless transmitter 3, the input detecting circuit 33, measures the normally open contact 31, When the open state is turned to the closed state, as described above, the wireless output is transmitted, so that the output 埠44 emits sound and light for the user to confirm, and the pure signal is automatically stopped only after about 8 seconds, so even The relay will not return, and it will not ring.

At this time, although the heating rod is not heated, the hot water continues to flow out, so the hot water in the heat exchanger 72 (commonly known as the water tank) is gradually replaced by cold water until the user feels the water temperature drops and closes the hot water valve. At this time, the heat exchanger 72 has all the inside of the cold water, and the inside of the water heater naturally does not generate scale, and after the user leaves, if the water button 11 is not pressed any more, the above components and equipment are kept powered off. It will not consume energy.

Until the next one uses hot water, the waterproof button 11 must be pressed again, and the relay 29 is output, that is, the operation is stopped and reset, and the normally closed contact 30 of the relay is changed from the open state to the closed state, and the electronic controller thereof 61, that is, the power amplifier 62 can be driven in accordance with the temperature setting, so that the four power relays 63, 64, 65, and 66 are driven by the power amplifier, and the four normally open contacts 67, 68, 69, and 70 are thus closed. Then, the heating rod 71, that is, the power supply, the water heater starts to heat until the water temperature reaches the set temperature, and then the automatic temperature adjustment is accepted.

Since the previous user used the hot water, the next one used the hot water. This period of time may be very fast, or it may be pulled for a long time, even for several days. During this period, the invention can effectively reduce the power loss of the water heater. The current one presses the waterproof button, the relay 29, has the action, The normally closed switch 30 is thus open and maintained, and the power supply of the electronic controller 61 becomes an open circuit, the functions of the electronic controller are suspended, the power amplifier 62 has no power, and the four power relays 63, 64, 65 and 66 Will not act, the corresponding normally open contacts 67, 68, 69 and 70, are open circuit, heating rod 71, that is, no heating, especially the water heater with automatic constant temperature control, once the electronic controller of the power supply is open And maintain, its constant temperature control function is temporarily canceled without heating, and there is no need to intermittently heat in order to maintain the set temperature, especially when it is not used for a long time, and the water temperature is controlled by automatic constant temperature, it is a considerable energy waste. Therefore, the present invention can effectively save energy.

The electric water heater of Figure 7 uses four power relays as an example. In fact, two power relays are also used. What kind of power heaters are used and how many power relays are used depends on the amount of current of the heating rod, regardless of the electric energy. The number of power relays for water heaters and the voltage source used can be controlled by the present invention for energy saving and carbon reduction.

As far as the invention is used in an electric water heater, the prevention of scale formation and the removal of scale from old products are still beneficial.

Of course, in some cases, if the location of the hot water used is very close to the water heater, the present invention can adopt the wired transmission control method and the wired and transmitted sound and light device to replace the above wireless transmission mode, and obtain the same energy saving and anti-scaling. effect.

The invention can also adopt the wireless remote control as the main control, and the sound and light device with the wired transmission is confirmed as a return, because the transmission of the sound is also a long distance, so it is also feasible to use the wired sound and light transmission instead of the wireless sound and light transmission.

If the user can reach out to the water heater when using hot water, then the manual switch element or manual delay switch element and water heater can be installed near the water heater. The power supply circuit with the electronic controller is connected in series, and the obtained energy-saving anti-scaling function is also the same.

For a gas or electric water heater to supply more than one hot water space, the present invention can adopt a plurality of high frequency transmitters, corresponding to a high frequency receiver, and can achieve the effect of energy saving and anti-scaling, and is not subject to many The limitation of the premises, and its sound and light return confirmation can be used only with a set of acousto-optic devices transmitted wirelessly or by wire.

In summary, the utility model can be applied to both a gas water heater and an electric water heater, which can save energy and reduce carbon, and can also take into consideration safety, and can be applied to new water heaters and old products. It can prevent the formation of scale, remove the scale in the old product and extend the service life of the water heater, and save the cost of regularly removing the heat exchanger.

According to the previous data collection, the present invention calculates the carbon emissions and economic benefits in a conservative manner, and has the opportunity to reduce the annual carbon dioxide emissions by 680,000 tons, equivalent to the annual carbon absorption of 1771 Da'an Forest Park.
