Problems solved by technology

[0006] However, the relative positions of the combustion box and the burner unit are sometimes misaligned due to the influence of strain on the combustion box or the burner unit or assembly errors
When such a deviation occurs, the distance from the tip of the ignition electrode to the unit burner is extended to be greater than the specified distance, and it cannot be expected that the ignition electrode can perform a good spark discharge, which may cause poor ignition.

Embodiment Construction

[0029] One embodiment of the present invention will be described with reference to the drawings.

[0030] Such as figure 1 As shown, the combustion device 1 of the present embodiment is accommodated in the case 3 of the water heater 2 and constitutes an essential part of the water heater 2 . In addition, considering the convenience of description, figure 1 A state in which the front surface of the case 3 of the water heater 2 is opened is shown. Normally, when the water heater 2 is used, the front surface of the casing 3 is closed by a front panel not shown. Furthermore, by removing the front panel of the housing 3, the front of the housing 3 of the water heater 2 is largely opened, which is suitable for maintenance of the combustion device 1 and the like.

[0031] In addition, in figure 1 Among them, reference numeral 4 represents a heat exchanger, reference numeral 5 represents a water supply pipe connected to the upstream side of the heat exchanger 4, reference numeral ...

Abstract

The invention provides a combustion device. The combustion device comprises a combustion unit (11), a combustion case (8) and an ignition electrode (41). In the combustion unit (11), a burner support (13) is used for integrally supporting multiple single burners (12); a combustion housing (8) contains the combustion unit (11); the ignition electrode (41) generates a spark toward the single burner (12), in order to carry out ignition. An open surface (37) is arranged in the front of the combustion housing (8). A front plate (20) of the burner support covers the open surface (37) of the combustion housing (8). The ignition electrode (41) is installed on the front plate (20) of the burner support (13). The combustion device (1) can be used for precisely arranging the distance between a tip of the ignition electrode to the single burner, in order to prevent bad ignition.

Description

technical field [0001] The invention relates to a combustion device for a water heater. Background technique [0002] As such a device, there is known a device in which a burner unit is accommodated in a rectangular cylindrical interior, and a heat exchanger or the like provided on the upper portion of a combustion box is heated by combustion of the burner unit. [0003] The burner unit includes a plurality of unit burners and a burner support body that connects these unit burners in a row and supports these unit burners integrally. The burner support body supports the unit burners in the arrayed state so as to surround the unit burners. [0004] Also, in this combustion device, an ignition electrode for igniting the burner unit is mounted on the front plate of the combustion box. The tip of the ignition electrode faces one of the unit burners constituting the burner unit, and spark discharge is generated between the ignition electrode and the unit burner, thereby igniting...
