Embodiment approach 1

[0036] figure 1 It is a block diagram showing a schematic configuration of a system including a combustion device and an alarm according to Embodiment 1 of the present invention. Such as figure 1 As shown, the combustion device 1 in this embodiment includes a combustion unit 8 for combusting fuel gas and a control board 9 including a control unit 3 connected to the combustion unit 8 and controlling the combustion unit 8 . The control unit 3 includes a computer that performs arithmetic processing, such as a microcomputer. Furthermore, the combustion device 1 includes a notification unit 6 for notifying various information and an operation unit 7 capable of predetermined input operations. The configuration of the notification unit 6 is not particularly limited, and various notification methods such as display on a display, notification by turning on or off a lamp, and notification by a buzzer or sound can be adopted.

Embodiment approach 2

[0073] Next, Embodiment 2 will be described. In this embodiment, the same reference numerals are assigned to the same configurations as those in Embodiment 1, and description thereof will be omitted. The combustion device 1 in this embodiment also has the same figure 1The same structure as shown in the structure. The combustion device 1 in the present embodiment is different from the first embodiment in that the operation unit 7 is also used as the second operation for switching the alarm information based on the signal from the alarm 2 into valid or invalid. function. Furthermore, data indicating whether the alarm information is enabled or disabled by switching operation of the operation unit 7 functioning as the second operation unit is stored in the storage unit 5 . Moreover, the control unit 3 is configured so that when a signal from the alarm 2 is input to the control unit 3 in a state where the data indicating that the alarm 2 is in a connected state and the alarm in...

Abstract

The invention provides a combustion device capable of connecting an alarm with no complex operation in the combustion device construction; the combustion device is connected with an alarm used for detecting carbon oxide and sending alarms, and comprises a control portion, a connecting portion and a storage portion; the connecting portion can connect the control portion with the alarm; the storage portion can store whether the alarm is connected or not; the control portion can provide alarm connection state data to the storage portion when the alarm is connected with the connecting portion.

Description

technical field [0001] The invention relates to a combustion device. Background technique [0002] Combustion devices such as water heaters are known to have an alarm (CO alarm) that detects carbon monoxide and issues an alarm based on its concentration (for example, refer to Patent Document 1, etc.). In order to clarify the normal operation of such an alarm, the combustion device is configured to perform a disconnection function that determines whether the alarm is disconnected (Japanese: disconnection) based on the input voltage input from the alarm to the control unit of the water heater. Open judgment processing. [0003] In addition, depending on the type of the combustion device, such an alarm may be externally attached as an attachment that can optionally be connected. Even in a combustion device capable of installing an external alarm in this way, it is necessary to perform a disconnection judgment process when the alarm is connected, but it is necessary to disting...
