Abstract

(57) [Summary] [Purpose] To provide an outdoor gas appliance that is low in cost, prevents wind and rain from entering, has a smooth exhaust gas flow, and has stable combustion. [Structure] Upper edge 1a of exhaust hole 1 for discharging exhaust gas 8
Gas appliance for outdoor use in which the lower edge 1b is projected.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improvement of wind resistance and rain resistance in an exhaust hole of an outdoor gas appliance.

[0002]

[Prior Art]

 Conventionally, in order to improve wind resistance and rain resistance, outdoor gas appliances have been equipped with plates that satisfy the respective performance inside the exhaust holes. For example, as shown in FIG. 3, in order to prevent wind and rain 9 from spraying obliquely from above toward the exhaust hole 1 as shown by the arrow to prevent the inside of the exhaust collecting box 2 from entering the heat exchanger or the combustion part, The rain gutter 6 is provided in the exhaust collecting box 2 or, as shown in FIG. 4, a baffle plate 7 is provided at a position facing the rain gutter 6 in the exhaust collecting box 2.

[0003]

[Problems to be solved by the device]

 However, in the structure shown in FIG. 3, when the exhaust gas 8 is discharged from the exhaust hole 1, the exhaust gas 8 is curved by the rain gutter 6 as shown by the arrow and does not flow smoothly, as shown in FIG. Even if the mounting angle of the rain gutter 6 is changed so that the exhaust gas 8 can easily flow, the flow becomes worse depending on how the baffle plate 7 is mounted, and in any case, combustion becomes unstable. Further, there is a drawback that the cost is increased because the plate or the like is provided. On the other hand, in the case of forced combustion gas appliances, wind noise is generated when the wind is strong, and the noise becomes high.In gas appliances of the proportional combustion type, the fire is extinguished by strong wind when small capacity combustion occurs. There is. The present invention provides an outdoor gas appliance that solves the above problems.

[0004]

[Means for Solving the Problems]

 The present invention relates to an outdoor gas appliance in which an upper edge of an exhaust hole for exhausting exhaust gas is projected from a lower edge.

[0005]

Embodiments The outdoor gas appliance of the present invention is preferably applied to a gas appliance exclusively for outdoor installation. Further, as shown in FIG. 1 which is an embodiment of the present invention, the upper edge 1a projects from the lower edge 1b. It is preferable that the length L to be set is equal to or larger than the outlet width H of the exhaust hole, because the intrusion of wind and rain is almost eliminated. The shape of the exhaust hole is preferably square or oval. 2 shows an overall view of an outdoor gas appliance according to an embodiment of the present invention, in which exhaust gas 8 generated by the burner 4 is smoothly blown from the outlet of the exhaust hole 1 through the heat exchanger 3 by the blower 4. Is discharged to. Even if the wind and rain blows on the exhaust hole 1 from diagonally above, the wind and rain hit the upper edge and not the lower edge, so it is difficult to enter the inside of the exhaust hole 1.

[0006]

[Effect of the device]

 According to the present invention, it is possible to provide an outdoor gas appliance that is low in cost, prevents intrusion of wind and rain, has a smooth exhaust gas flow, and has stable combustion.
