Heater and burner head assembly and control module therefor
View Patent ↗A burner head assembly for a burner includes a housing having a hollow interior and an exterior. There is a control module within the hollow interior. The module has internal connectors within the hollow interior and external connectors on the exterior of the housing, whereby electrical connections to the module can be made internally and externally with respect to the housing without requiring apertures in the housing and wiring extending through the apertures. For example, the control module may include a circuit board, the circuit board having a portion within the hollow interior and which extends to the exterior. The exterior and interior connectors are connected to the circuit board. The housing may have two portions, the control module being fitted between the two portions of the housing. Preferably the control module is sealingly received between the two portions of the housing.
1. A burner head assembly for a heater, the assembly comprising:
a housing having two portions, a hollow interior and an exterior; and
a control module within the hollow interior between the two portions of the housing, the module having internal connectors within the hollow interior and external connectors on the exterior of the housing, whereby electrical connections to the control module can be made internally and externally with respect to the housing without requiring apertures in the housing and wiring extending through the apertures, the control module including a circuit board, the circuit board having a portion within the hollow interior and extending to the exterior, the exterior and interior connectors being connected to the circuit board.
2. The assembly as claimed in claim 1 , wherein the housing is cylindrical, the control module having a circular outer surface adjacent to the exterior of the housing.
3. The assembly as claimed in claim 2 , wherein each of the two portions of the housing has an annular surface adjacent to the exterior of the housing, the control module being received between the annular surfaces.
4. The assembly as claimed in claim 3 , wherein the control module is sealingly received between the two portions of the housing.
5. The assembly as claimed in claim 4 , wherein the two portions of the housing have interior annular shoulders which receive mating shoulders on the control module.
6. The assembly as claimed in claim 1 , wherein the control module is rotatably adjustable relative to the two portions of the housing, whereby the exterior connectors can be rotated to different positions about the housing.
7. The assembly as claimed in claim 6 , wherein the control module is rotatable to positions 180 degrees apart relative to the housing.
