Abstract
Abstract A modular electronic control housing assembly 10 having a housing 32, a removable front plate 36, and a chassis 34 for mounting control components. The housing 32 includes an enclosed top 40, an enclosed back 42, and enclosed sides 44 having flanges 48 projecting therefrom. The chassis 34 includes a base 66, a front wall 68, and flanges 70 projection from the wall 68 having a side flange 72 and outwardly projecting front flanges 74. A plurality of electrical connectors 90 are mounted to the base 66 through openings 92. When the modular spa control assembly 10 is assembled, the front flanges 74 on the chassis 34 are clamped between the front plate 36 and the flanges 48 on the sidewalls 44 of the housing 32, thus supporting the chassis 34 within the housing 32 without requiring an enclosed bottom. The control assembly 10 is quickly disassembled by unplugging the power cord 28 and the plurality of plugs 30, removing the fasteners 38 and the front plate 36, and taking the chassis 34 out of the housing 32.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
120 words
A modular electronic control housing assembly for a spa water conditioning system, the assembly comprising: (a) a housing having an open front and an open bottom; (b) a front plate removably attached to said housing to cover said open front of said housing; (c) a chassis removably mounted within said housing, said chassis comprising a base, a front wall depending from said base; and (d) a plurality of flanges projecting from said wall, each of said flanges comprising a first flange projecting forward from the side of said wall and a second flange projecting outward from said first flange, each of said flanges being clamped between said housing and said front plate to thereby support said chassis in said housing.
Claim 2
Dependent Claim
120 words
A modular electronic control housing assembly for a spa water conditioning system, the assembly comprising: (a) a housing having an open front and an open bottom; (b) a front plate removably attached to said housing to cover said open front of said housing; (c) a chassis removably mounted within said housing, said chassis comprising a base, a front wall depending from said base; and (d) a plurality of flanges projecting from said wall, each of said flanges comprising a first flange projecting forward from the side of said wall and a second flange projecting outward from said first flange, each of said flanges being clamped between said housing and said front plate to thereby support said chassis in said housing.
Claim 3
Dependent Claim
22 words
The assembly of claim 1, wherein said front plate includes openings to provide access to selected control components mounted on said chassis.
Claim 4
Dependent Claim
150 words
A modular electronic control housing assembly for a spa water conditioning system, the assembly comprising: (a) a housing having an enclosed top, enclosed sides, an enclosed back, and an open front and an open bottom; (b) a front plate removably attached to said housing to cover said open front of said housing; and (c) a chassis having electrical components mounted thereto, said electrical components having quick disconnect means to facilitate detachment of the electrical components from said spa water conditioning system, said chassis comprising a flat base, a front wall depending from said base; and (d) plurality of flanges projecting from said wall, each of said flanges comprising a first flange projecting forward from the side of said wall and a second flange projecting outward from said first flange, each of said flanges being clamped between said housing and said front plate to thereby support said chassis in said housing.
