Description

{Method To Keep the Set Room Temperature During Intermittent Heating Mode}

The present invention relates to a method of maintaining indoor temperature, and more specifically, to a heating repeat timer that restarts the heating repeat timer operation to maintain the indoor temperature above the set temperature when the indoor temperature falls below a certain temperature during the repeat heating timer operation. This is about how to maintain the set indoor temperature while driving.

In general, the boiler's heating control system controls the amount of heat by burning the boiler according to the heating temperature set by the consumer, and the actual heating water tap temperature reaches the first high cut temperature, which is set at a certain temperature higher than the user's heating temperature. Or, when the second high cut temperature, which is an absolute temperature to prevent reaching the boiling point, is reached, combustion is stopped and extinguished. Also, during extinguishment as described above, the actual heating water tap temperature measured by the temperature sensor is the first re-extinguishment temperature. Control is carried out to repeat the operation of resuming combustion when the combustion temperature is reached.

Figure 1 is a flowchart of a heating repetition timer operation process according to the prior art, and Figure 2 is a timing diagram of combustion permission and fire extinguishing timer operation. First, the user sets the heating combustion timer and heating fire extinguishing timer for the heating repetition timer operation.

The set heating combustion timer starts counting until the set end time.

Referring to FIG. 2 (A), before the heating combustion timer expires, heating combustion is performed for the permitted combustion time to raise the current indoor temperature to the first set temperature set by the user and then extinguished.

In addition, when the heating combustion timer ends, the set heating extinguishing timer starts to be counted, and when the set heating extinguishing timer ends, the heating combustion starts and the heating combustion timer is counted for the set time.

Referring to Figure 2 (B), since combustion is performed only during the combustion permission time, the indoor temperature is maintained by repeating the set combustion timer and extinguishing timer cycles.

The heating repeat timer operation method according to the prior art excludes combustion conditions for the purpose of preventing freezing during the heating repeat timer operation, and reburns until the fire extinguishing timer is completed even if the indoor temperature falls during the fire extinguishing timer count. It was not implemented.

This requires setting a long fire extinguishing timer due to the consumer going out for a long time, but at the same time, there was a problem in that it was difficult to set an appropriate repeat timer when the indoor temperature was wanted to be maintained above a certain temperature.

Domestic Patent Registration No. 10-1344703 (announcement date 2013.12.26.)

Therefore, in order to improve the problems of the prior art, the present invention provides a setting during heating repetition timer operation to maintain the set indoor temperature by re-executing the heating repetition timer operation when the indoor temperature falls below a set certain temperature during the heating repetition timer operation. The purpose is to provide a method of maintaining indoor temperature.

In order to achieve the purpose of the present invention, the method of maintaining the indoor temperature set during the heating repetition timer operation is to set the first set temperature, the heating combustion timer, and the heating extinguishing timer to the control unit for the heating repetition timer operation through the thermostat by the user. In the method of maintaining indoor temperature by repeatedly operating combustion and fire extinguishing at time intervals set by, the control unit adjusts the current indoor temperature to the first set temperature until the heating combustion timer set as the repetitive heating timer operation starts ends. A first process of performing combustion to maintain; a second process of starting the heating extinguishing timer count when the heating combustion timer expires; A third process of comparing the current indoor temperature and the second set temperature during the heating extinguishing timer count; A fourth process of operating heating and extinguishing when the current indoor temperature is higher than the second set temperature as a result of the comparison in the third process; and a fifth process of returning to the first process to restart the heating repetition timer operation when the current indoor temperature is lower than the second set temperature as a result of comparison in the third process.

Here, the fourth process starts counting the actual heating extinguishing timer from the time the heating extinguishing starts and returns to the third process until the set heating extinguishing timer ends.

Additionally, in the fourth process, the second set temperature is set to a temperature value below a certain temperature value based on the first set temperature, or is set to a fixed temperature value.

The method of maintaining the indoor temperature set during the heating repeat timer operation according to the present invention is to set the fire extinguishing timer for a long time using the heating repeat timer operation when the user is away from home for a long period of time due to going out. Even if the temperature goes down to low, no re-combustion is performed except for operation for the purpose of preventing freezing until the fire extinguishing timer expires. However, in the present invention, the current indoor temperature is lower than the second set temperature calculated from the first set temperature set by the manufacturer or consumer. If the heating repeat timer operation is changed and restarted, it has the effect of preventing the indoor temperature from falling below a certain temperature even during a long-set extinguishing timer, and the changed heating repeat timer is notified to the remote control and the user's smart device to inform the user. To prevent confusion and allow comparison between the combustion time and fire extinguishing time set by the user with the actual combustion time and fire extinguishing time, data is transmitted from the main unit to the remote control and smart device to determine the first set temperature, second set temperature, and combustion time. User convenience can be improved by guiding consumers to change the timer and fire extinguishing timer when necessary.

It consists of a first control unit 110 that generates a driving signal and transmits it to the boiler main body 200 through a communication unit.

Here, the first control unit 110 includes a heating combustion timer setting unit 111 that sets the heating combustion timer input by the user through the input unit 121, a heating and extinguishing timer setting unit 112 that sets a heating and extinguishing timer, and , a set temperature determination unit 113 that receives temperature settings such as the first set temperature, a display control unit 114 that controls the display of the set temperature, boiler operation status, etc. on the display unit 122, and the indoor temperature sensor. It consists of an indoor temperature input unit 115 that receives the indoor temperature measured through 123.

The boiler main body 200 includes a second control unit 210 that receives the signal transmitted from the temperature controller 100 through a communication unit, counts the set heating combustion timer and heating extinguishing timer, and controls heating or combustion operation, A combustion and water circulation driving device 221 that drives combustion/extinguishing and water circulation of the boiler under the control of the second control unit 210, and a tapping temperature sensor 222 that measures the temperature of hot water passing through the heat exchanger. It is composed.

Here, the second control unit 210 includes a heating combustion timer 211 that counts the set heating combustion time, and the indoor temperature input and the first set temperature while the heating combustion timer 211 performs the heating repetition timer operation. A first judgment unit 214 that compares and determines whether the heating combustion permission condition 1 is met, a heating extinguishing timer 213 that counts the set heating extinguishing time, and a second heating extinguishing timer 213 that is set while counting.

The method of maintaining the set indoor temperature during operation of the heating repetition timer according to an embodiment of the present invention using each boiler control device configured as described above will be described in detail with reference to the attached FIGS. 3 to 5 as follows.

As shown in Figure 4 as a flowchart of the process of maintaining the set indoor temperature during operation of the repeat heating timer according to an embodiment of the present invention, the user first starts the operation of the repeat heating timer through the input unit 121 of the thermostat 100. As the heating combustion timer and heating extinguishing timer are input, the input value set in the heating combustion timer setting unit 111 and the heating extinguishing timer setting unit 112 is transmitted through the communication unit to the heating combustion timer ( 211) and the heating and extinguishing timer 213 operate.

When the input settings of the heating combustion timer and the heating combustion timer are completed in the temperature controller 100 and the heating repetition timer operation begins, the heating combustion timer 211 starts counting until the set heating combustion timer ends. (S11)

When the heating combustion timer 211 starts counting, the first determination unit 214 determines whether heating combustion permission condition 1 is satisfied (S15).

The heating combustion permission condition 1 compares the first set temperature, which is the lower limit temperature set by the user, with the current indoor temperature measured by the indoor temperature sensor 123, and continues if the current indoor temperature is higher than the first set temperature. Maintain the extinguishing state and pause the count of the heating combustion timer (S21).

If the current indoor temperature is lower than the first set temperature, combustion is permitted, the combustion and water circulation driving device 221 is driven through the load driving control unit 216 to start combustion, and the heating combustion is performed. Restart the timer's count. (S17)(S19)

That is, as the combustion and water circulation driving device 221 is driven and combustion begins, the heating combustion count that was paused during the fire extinguishing time is restarted.

In this way, heating extinguishing and heating combustion are repeated so that the current indoor temperature maintains the first set temperature until the heating combustion timer expires, and the heating combustion timer also repeats pausing and restarting the count accordingly. . (S15~S21)

When the heating combustion timer ends, the heating extinguishing timer 213 starts counting until the set heating extinguishing timer ends (S23).

When the heating combustion timer 213 starts counting, the second determination unit 215 determines whether heating combustion permission condition 2 is satisfied. (S25)

Here, the heating combustion permission condition 2 is a process of comparing the current indoor temperature with a second set temperature that is set to a certain temperature value or lower than the first set temperature set by the user.

The second set temperature is a temperature value calculated from the first set temperature set by the user separately from the freeze prevention temperature automatically set during the boiler manufacturing process.

That is, the second set temperature is set to a fixed temperature value (e.g., 7°C) during the boiler manufacturing process to maintain a certain temperature value (k°C) or less at the first set temperature, or as shown in Equation 1 below: This is the calculated temperature.

Here, the constant temperature value (k℃) can be set to a fixed temperature value (for example, 10℃) during the boiler manufacturing process, and is set by the user as in Equation 2 below, but in Equation 2 below It can be set within a limited range as follows.

The k value can be set to be large to correspond to the set time of the heating extinguishing timer, as shown in the example in Table 1 below, and the second set temperature can be calculated to be lowered to correspond to the set time.

Therefore, the longer the fire extinguishing timer is set, the lower the second set temperature for re-combustion is set to increase the re-combustion time, thereby preventing the heating water from deteriorating below a certain temperature and controlling it to correspond to the fire extinguishing time desired by the consumer. can do.

As the count time passes, the second set temperature limited to the increased k value is calculated.

digestion

If the second set temperature set in the above process is higher than the current indoor temperature, the second determination unit 215 determines that the heating combustion permission condition 2 is met and restarts the heating repetition timer operation to increase the heating combustion timer count. Return to the starting step (S11).

In this way, when the heating repetition timer operation is restarted, the restart of the heating repetition timer operation is transmitted to the thermostat 100 or the user's smart device through the app through the data transmission unit 212, so that the user can It is possible to confirm that the start point of the heating repetition timer set by the user has changed, and the combustion and extinguishing time actually performed in the repetition timer section immediately before that is also transmitted to the temperature controller 100 or the app through the data transmission unit 212. It is transmitted to the user's smart device, etc., allowing the user to compare the combustion and extinguishing timer he or she has set with the actual combustion and extinguishing timer.

The user can use this as data necessary to change the first set temperature, second set temperature, heating combustion timer, and heating extinguishing timer according to his or her needs.

Meanwhile, if the heating combustion permission condition 2 is not satisfied, that is, if the current indoor temperature is higher than the second set temperature, the heating extinguishing timer 213 is turned on after extinguishing the fire through the load driving control unit 216. Run it to restart the actual heating and extinguishing timer count (S27).

When the heating combustion timer ends, it returns to the step (S11) of starting the first heating combustion timer count (S29).

Through this process, if the indoor temperature falls below the second set temperature during the heating extinguishing timer count, recombustion is performed to raise the indoor temperature to the first set temperature, thereby maintaining the indoor temperature at a constant temperature.

Referring to FIG. 5A, after performing combustion operation in the heating combustion timer section to raise the indoor temperature to the first set temperature, the heating extinguishing and heating extinguishing timer start counting, and the indoor temperature is increased before the set heating extinguishing timer ends. If it falls below the second set temperature, the heating combustion count is restarted along with re-combustion to raise the indoor temperature above the first set temperature.

That is, as shown in Figure 5b, the heating combustion timer and the heating extinguishing timer are set at point A, and combustion is performed for the time that the set heating combustion timer counts to raise the indoor temperature above the first set temperature, After the heating combustion timer ends, the set heating combustion timer starts counting.

If the indoor temperature falls below the second set temperature (second set temperature > current indoor temperature) before the heating extinguishing timer set at point A expires, the heating combustion timer and heating extinguishing timer are reset at that point (B). , heating is performed while the heating combustion timer is counting to increase the indoor temperature. When the heating combustion timer count ends, the heating combustion timer set at point B is restarted.

By repeating this process, combustion does not wait until the initially set heating extinguishing timer expires, but recombustion starts based on the second set temperature, so even if the heating extinguishing timer becomes longer, the constant temperature set by the user is maintained. can be maintained.

As described above, the method of maintaining the set indoor temperature during operation of the heating repetition timer according to the embodiment of the present invention, although described with reference to the limited embodiment and drawings, is not limited to this embodiment, and is not limited to this embodiment, and is not limited to this embodiment, and is not limited to this embodiment, and is not limited to the present invention.
