The present invention relates to a combustion control method and a device according to the outgoing function operation selection during heating mode combustion in a gas boiler, and in particular, when the outgoing function is selected in the heating mode combustion for a long time out, the predetermined temperature can be maintained. By keeping the indoor temperature at a minimum temperature, it is possible to reduce fuel consumption and to prevent the freezing of cold weather and to protect the plants and plants in the cold. And to the apparatus.

In the conventional gas boiler, when the user converts the operation mode to the out function, which is an optional function during the normal heating operation, the combustion proceeds to the fixed set temperature of the out function function with the indication of the out function function, but the fixed set temperature is maintained at a predetermined position ( For example, it is not displayed on the manual control device so that the operating temperature of the outgoing function operation is not known, and when the heating water rises to the fixed set temperature (HTset) during the outgoing function operation as shown in FIG. When the temperature falls below the fixed set temperature (HTset-1), combustion starts immediately. When the temperature of the heated water rises again and reaches the fixed set temperature (HTset), it is extinguished immediately and the temperature of the heated water is set again. When the temperature falls below HTset-1, combustion is immediately resumed.

In other words, the repetition of combustion and extinguishing is continuously performed within a short time, and thermal efficiency decreases due to the release and explosion ignition of fresh gas generated at each ignition, as well as the increase of gas consumption and the shortening of the extinguishing time. There was a problem that the consumption of gas is unnecessarily increased in the outgoing operation in which the operation is performed in a state in which the user is all out due to a decrease in latent heating efficiency during the time.

In addition, in the 'boiler temperature control device' of Korean Patent Application Publication No. 89-5473 (89. 5. 13), which has been previously disclosed and disclosed, even if the outgoing function is selected, the outgoing function operation detection temperature (eg, outside air temperature) 5 ° C and the operating temperature is stopped before the temperature reaches 35 ° C in the boiler, that is, the temperature is hard to be detected. Is not working well), it is difficult to achieve a certain purpose because the function of going out does not work, and when the operation temperature of the going out function is detected and operated, the temperature becomes 35 ℃ or less (in case of outside temperature, 5 ℃). Combustion of the burner is made, and then the operation of stopping the combustion is repeated when the comfort temperature goes out.

Therefore, as pointed out in the above, the number of 'on' and 'off' is greatly increased, resulting in an increase in the amount of incomplete combustion gas during ignition due to ignition noise, frequent on-off, and outflow of fresh gas before the ignition concentration of the gas. Problems such as increased gas consumption and reduced efficiency.

That is, in the on-off control method, it is impossible to proportionally control the amount of gas to maintain the set temperature according to the tapping temperature detection of the temperature detector. ℃) heating time can be reached within only 1 minute, so the set temperature is reached quickly and the gas supply is stopped when the set temperature is reached and extinguish fires. Because of the rapid fall, the combustion and the fire extinguishing operation is repeatedly performed in a fast time, so there is a problem as described above.

The present invention has been proposed to solve such a conventional problem, the gas boiler fixed setting to display the fixed set operation of the outgoing function operation when the user's selection function is converted to the outgoing function operation during normal heating combustion operation During the combustion process controlled by the temperature display function and the fixed set temperature, the combustion is stopped when the fixed set temperature is reached, and the heating water heated during the combustion is continuously circulated to maintain heating using latent heat for a certain time. When a certain time has elapsed and the reburn time has been reached, reburn is only carried out when the temperature of the heating water has fallen below a certain value from a fixed set temperature according to the outgoing function operation. If the temperature of the heating water drops below a certain level while maintaining it irrelevantly, reburn it immediately. It is easy for the user to judge the fixed set temperature of the functional operation, and the usability of the gas boiler is not only improved, but once the temperature of the heated water reaches the fixed set temperature, it is extinguished and maintained heating by the latent heat of the heated water for a certain time. Even if a certain time has passed after the fire extinguishing, the reburn can be performed only at a fixed value below a fixed value, thereby reducing the consumption of gas to a minimum and improving the functionality of the gas boiler.

If the tapping temperature (T ₂ ) of the heating water is continuously detected (S ₄ ) whether it is higher than or equal to the fixed set temperature (T ₁ ), the tapping temperature (T ₂ ) of the heating water is higher than the fixed set temperature (T ₁ ). Is equal to (YES in S ₄ ), the operation of the digestion timer having a driving time of a predetermined time (T _A ) is started (S ₅₁ ), and the electronic valves 51 and 52 are 'off' (S ₅₂ ). side 53: after the "oFF" (S _53), and a blower 23 is "off" (S _54), a predetermined time (T _a) can be heated by circulating heated for After performing the heating function by latent heat (S _6), a certain period of time (T _A) is when the lapse of the tapping temperature of the heating can (T _2), the fixed set temperature (T ₁₎ than a predetermined value (0.7) a lower predetermined temperature (T _{If it} is lower than or equal to ₁ x 0.7) and continues to detect (S ₈ ) and lower or equal (Y ₈ of S ₈ ), reburn is started (S ₉₁ ) and the blower 23, the electromagnetic valves 51 and 52 and After the proportional valve 53 is turned on (S ₉₂ → S ₉₃ → S ₉₄ ), a process of detecting whether the tapping temperature (T ₁ ) of the heating water is lower than or equal to the fixed set temperature (T ₁ ) (S ₄ It is a process of returning to).

If described with reference to Figures 1 to 4a, b of the effect of the present invention made with such a process and configuration as follows.

First, when the user presses the outgoing function operation button installed in the manual adjustment device 11 and the outgoing function operation is selected in the outgoing function operation selection unit 11a, the selection function operation reading unit 11b recognizes this and the driving unit ( Since a predetermined signal is outputted to the liquid crystal display control unit 11e through 11d), the liquid crystal display control unit 11e outputs a fixed set temperature (for example, 35 ° C) to go out on the liquid crystal of the fixed set temperature display unit 11f. Will appear.

The drive unit 11d outputs the outgoing function operation selection signal to the data input / output unit 11c, and the manual operation device data transmission / reception unit 13 selects this signal through the selection function operation determination command unit 113. It will be pulled to section 114.

Therefore, the switching mode determination unit 114 outputs the selection function driving drive signal to the driving unit 115, and the driving unit 115 receiving the signal outputs the outing function operation command through the outing function operation combustion command unit 116. Will be lowered.

At this time, the tapping temperature T ₂ of the heating water to be compared with the fixed set temperature T _{1 of the} outgoing function operation is detected by the thermistor 34 ″, and then the tapping temperature detector 14 and the A / D converter ( The digital signal is converted into a digital signal through 15), and is recognized by the tapping temperature recognition unit 117 through the A / D conversion input unit 118 in the microcomputer 10 'and then sent to the temperature comparison unit 119.

Therefore, the temperature comparing unit 119 receives the reference temperature T ₁ of the fixed temperature set value (35 ° C.) output from the outgoing function operation combustion command unit 116 and the heating water tapping temperature received from the tapping temperature recognition unit 117. (T ₂ ) are compared with each other. As a result, when the state T ₁ ≤ T ₂ , the next execution command unit 120 recognizes this and transmits the same to the fire extinguishing control unit 123 through the fire extinguishing unit 122.

At this time, the fire extinguishing controller 123 receives the counting of the timer 112 and outputs a predetermined control signal to the functional part driver 126, and the functional part driver 126, the functional part output signal group 127, and D The electronic valves 51 and 52 and the proportional valve 53 are closed via the / A conversion group 16, and the blower 23 is stopped to maintain fire extinguishing for a predetermined time T _A.

At this time, since the circulation pump 35 in the boiler is continuously driven while the fire is maintained for a predetermined time (T _A : 45 minutes), the circulation of the heating water is continued to use the latent heat of the heating water that has been absorbed during combustion. Minimal heating can be maintained.

After that, when a predetermined time (T _A ) has elapsed, the fire extinguishing controller 123 instructs the temperature comparison unit 119 to compare the fixed set temperature T ₁ , which is a reference temperature, with the heating hot water temperature T ₂ again. , The temperature comparison unit 119 once received the command from the fire extinguishing control unit 123 outputs the comparison value to the first combustion driving unit 121.

At this time, when the tapping temperature T ₂ of the heating water is 30% or more lower than the fixed set temperature T ₁ , that is, when T ₁ ≤ T ₁ × 0.7, the first combustion operation driving unit 121 performs the next execution command unit ( Since the combustion output signal is transmitted from the 120, the next execution command unit 120 transmits a predetermined combustion signal to the combustion (maintenance) output unit 124 so that the second combustion operation unit 125 functions as an ignition command. Since it is sent to the component drive unit 126, the blower 23 is rotated, the electromagnetic valve (51, 52) and the proportional valve (53) is opened to start the combustion.

However, as a result of comparing T ₁ and T ₂ in the first combustion driving unit 121, when T ₂ ≤ T ₁ × 0.7, a predetermined extinguishing output signal from the next execution command unit 120 to the extinguishing output unit 122. This is to continue to output, wherein the fire extinguishing control unit 123 under the control of the fire extinguishing output unit 122 does not receive the counting output signal of the timer 122, the electronic parts (51, 52) to the functional component drive unit 126 ), While controlling the proportional valve 53 and the blower 23 not to continue to operate, the holding time of the predetermined time T _A is released through the temperature comparing unit 119, and the constant T ₁ , T ₂ When the comparison value is T ₁ ≤ T ₂ × 0.7, the first combustion operation driver 121 outputs a combustion output signal to the combustion (maintenance) output unit 124 immediately through the next execution command unit 120.

At this time, the second combustion operation driver 125 controlled by the combustion (holding) output unit 124 gives a predetermined ignition command to the functional part driver 126, so that the blower 23 rotates. As the electromagnetic sides 51 and 52 and the proportional side 53 are opened, ignition is started and combustion of the outgoing function operation by proportional control is resumed.

As such, after outputting the fire extinguishing signal from the fire extinguishing output unit 122, the fire extinguishing control unit 123 stops combustion for a predetermined time (T _A ), and in the process of re-ignition a fixed set temperature (T ₁ ) and the reference temperature By comparing the tapping temperature (T ₂ ) with each other and instructing the reburn output only when the latent heat of the heating water is sufficiently generated, it is possible to maximize the gas saving operation.

On the other hand, Figure 3 is a flow chart showing the method of the present invention, first while using the gas boiler in the heating mode (S ₁ ) the user presses the outgoing function operation selection button installed in the manual control device 11 to go out to go out When the function operation selection unit 11a recognizes this and selects the outgoing function operation (S ₂ ), the selection function operation reading unit 11b reads the fixed operation setting through the driving unit 11d and the liquid crystal display control unit 11e. The fixed set temperature T ₁ is displayed on the temperature display unit 11f and input to the microcomputer 10 'through the data input / output unit 11c and the data transmitting / receiving unit 13 to perform the outing function operation. Done.

In this way, while the outgoing function operation by the outgoing function operation selection is performed, in the temperature comparison unit 119, the tapping temperature T ₂ of the heating water tapping out of the primary heat exchanger 24 is greater than the fixed set temperature T ₁ . It continuously detects whether it is higher or equal (S ₄ ), and as a result, when the tapping temperature (T ₂ ) of the heating water becomes higher than or equal to the fixed set temperature (T ₁ ), the driving time of the predetermined time (T _A ) is immediately determined. The driving of the fire extinguishing timer is started (S ₅₁ ) and the driving of the electromagnetic valves 51 and 52, the proportional valve 53 and the blower 23 are blocked (S ₅₂ , S ₅₃ , and S ₅₄ ) while maintaining the extinguishing state. During the operation of the fire extinguishing timer (ie, T _A time), the minimum heat is maintained by the latent heat of the endothermic heating water during combustion (S ₆ ).

Then, when the driving time (T _A ) of the digestion timer has elapsed (S ₇ ), continuously detecting whether the tapping temperature (T ₂ ) of the heating water falls below a predetermined value (0.7) below the fixed set temperature (T ₁ ) S ₈ ), even until this time (that is, even when the driving time (T _A ) of the digestion timer has elapsed) for a predetermined time (during T _B time in FIG. 4b) until T ₂ ≤ T ₁ × 0.7 state. As it is to cut off the driving of the electromagnetic valve 51, 52, proportional valve 53 and the blower 23, it is possible to reduce the waste of unnecessary gas to the minimum and to make the most of the heating water.

Then, when the flow of a predetermined time T ₁ ≤T ₁ × 0.7 state, to the re-ignition burners to immediately reheat start (S _91), and at the same time the blower 23, the electronic valve (51, 52) and the proportional change ( 53) to start outgoing function operation combustion.

On the other hand, even if the tapping temperature (T ₂ ) is lowered below the fixed set temperature (T ₁ ) × 0.7 within the time that the digestion timer is being driven for a certain time (T _A ), the fixed time ( Until T _A ) has elapsed, as shown in FIG. 4B, re-ignition is not performed, but if T _A has elapsed, T ₂ ≤ T ₁ × 0.7 is already present.

As described above, according to the present invention, when the user goes out of the function selection button is pressed, the fixed set temperature according to the function of the outgoing function is displayed on the manual control device, and the extinguished function is fixed at a fixed set temperature (T ₁ ). During (T _A ), the minimum heating can be maintained at the endothermic temperature of the previous combustion, that is, the latent heat of the heating water, and after a certain time (T _A ), about 30% lower than the fixed set temperature during the reburning process. Fire extinguishing operation is continued until the tapping temperature (T ₂ ) of the heating water is detected, and reburning is performed when T ₂ ≤T ₁ × 0.7, thereby saving gas and preventing freezing of cold weather. You can protect the indoor copper and plants.
