Abstract

<P>PROBLEM TO BE SOLVED: To provide a timer device of a combustor capable of easily setting two kinds of timer functions by everybody. <P>SOLUTION: This timer device comprises a first timer 1 for starting combustion operation at a predetermined time, and a second timer 6 for stopping combustion operation after the passage of a specific time from the set time. The second timer 6 starts its down-count to the stop of the combustion, simultaneously with the start of counting by the first timer 1, thus the second timer 6 can be automatically set by setting the first timer 1, which is very convenient and dispenses with troublesome operation. The timer functions can be easily utilized even by a woman, a child and an aged person, and the timer device can be stably used at any time without false operation. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a timer device for a combustor having two types of timer functions.

Conventionally, in this type, when a good morning timer, which is a first timer for starting combustion at a set time during combustion, is set, combustion is stopped for safety and counting of the good morning timer is started. In order to continue the combustion, it was necessary to set the nighttime timer after operating the nighttime timer which is the second tamma that stops the combustion at a predetermined time after setting. (For example, see Patent Document 1.)
JP-A-5-172400

  By the way, with this conventional device, if the sleep timer is not set, heating will be stopped. In addition, the timer function, which is a convenient function, cannot be used well by elderly people, and the usability is extremely poor.

  In order to solve the above problems by focusing attention on this point, the present invention provides a first timer for starting the combustion operation at a preset time, and the combustion operation after a predetermined time has elapsed from the set time. The second timer is provided with a second timer to be stopped, and the second timer starts counting down to the stop of combustion simultaneously with the start of counting of the first timer.

  According to a second aspect of the present invention, the count start of the first timer and the down count of the second timer are performed by pressing a timer switch.

  According to a third aspect of the present invention, only the setting of the second timer is canceled by continuously pressing the timer switch after pressing the timer switch for setting the timer.

  According to the first aspect of the present invention, by setting the first timer, the second timer is automatically set, which is very convenient and does not require troublesome operation. It can be used and can always be used safely without worrying about malfunctions.

  According to the second aspect of the present invention, the count of the two timers is started simultaneously by only one operation of pressing the timer switch after setting the time at which combustion is to be started in advance. It is possible to know the time of fire extinguishing due to the ease of use.

  According to claim 3, when only the first timer is used and the second timer is not used, the setting of the second timer is canceled by pressing the timer setting timer switch twice in succession. It is easy and simple.

Next, a timer device for a combustor according to the present invention will be described based on an embodiment shown in the drawings.
1 is a first timer (a good morning timer) that counts up to a preset time and outputs to the burner unit 2 when the set time and the current time match to start combustion. 3 and the minute button 4 are connected, and a timer switch 5 that starts counting the first timer 1 by pressing after setting the time is also connected.

  6 is a press of the timer switch 5, and starts counting down in response to the output from the first timer 1, and is a second timer (sleep timer) that stops the combustion of the burner unit 2 after a predetermined time, here, 1 hour. The predetermined time is an invariable constant time set in advance. By pressing the timer switch 5 twice continuously when the timer is set, the operation start output from the first timer 1 to the second timer 6 is prohibited. The setting of the timer 6 is canceled and only the first timer 1 is set.

  Reference numeral 7 denotes a microcomputer incorporating the first timer 1 and the second timer 6, which burns with outdoor air, heats the exhaust gas after combustion and room air, heats the room, and exhausts the heat after the heat exchange. The main control of a forced supply / exhaust type combustion apparatus that exhausts gas to the outside is performed. Combustion and stop of the burner unit 2 are controlled by turning on and off the operation switch 8.

  Reference numeral 9 denotes a liquid crystal display, which displays the operation status of the combustion device, the current time, room temperature, set temperature, and the like as outputs from the microcomputer 7, and sets and displays the time of the first timer 1 and The operating status is also displayed.

Next, the operation of this embodiment will be described based on the flowchart of FIG.
When the combustor (not shown) is burning before going to bed, the next morning combustion start time is set by the hour button 3 and the minute button 4. (Step 10)

  The process proceeds to step 11 to determine whether the timer switch 5 has been pressed. If YES, the process proceeds to step 12 to determine whether the dimmer switch 5 has been pressed twice more continuously. The timer 1 and the second timer 6 are started. In step 13, the first timer 1 starts counting, and the second timer 6 starts down-counting.

In step 14, the downcount of the second timer 6 becomes 0, and when 1 hour of the predetermined time has elapsed, the process proceeds to step 15 to stop the combustion. The operation is stopped to stop the combustion, and the operation of the second timer 6 is canceled and only the first timer 1 is operated.
Further, the routine proceeds to step 16 where the first timer 1 reaches the set time, so that the combustion is started at step 17 with YES.

Therefore, by setting the good morning timer, which is the first timer 1, the good night timer, which is the second timer 6, is automatically set, so it is very convenient and does not require any special operation. Can be used.
When the second timer 6 is not needed, it can be released simply by pressing the timer switch 5 once after the timer setting, and the release is extremely simple and easy to use.
