Abstract

Abstract A water supply unit for an ice-making machine provided with a pair of freezing plates each presenting number of vertically extending partitions on their front sides, the freezing plates being mounted in an upright position with their rear sides facing to each other, and with a cooling coil mounted between the rear sides of the freezing plates. The water supply unit is placed on the top of the freezing plates and has an ice-making water conduit section connecting to the front surfaces of the freezing plates via water supply plates and a flushing water conduit section connecting to the rear sides of the freezing plates. The flushing water conduit section of the supply unit is received into and fitted between the upper ends of the freezing plates for securely positioning the water supply unit with respect to the freezing plates.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 209 words
An ice-making machine comprising: a pair of approximately vertically extending, spaced apart, parallel freezing plates having respective opposing rear faces and having respective front faces opposite said rear faces, said front faces having vertically extending, horizontally spaced apart partitions projecting outwardly therefrom so as to provide between said partions portions of said front face defining freezer sections, said opposing rear faces being spaced apart by a predetermined gap; a cooling coil positioned between and secured to said rear faces in said gap; and a water supply unit on the top of said freezing plates, said water supply unit including an ice-making water conduit, water guide plates extending downwardly from said ice-making water conduit into respective spaces between adjacent ones of said partitions toward said freezing sections, so as to direct ice-making water from said ice-making water conduit onto the respective freezing sections and position said water supply unit with respect to said freezing plates, and a flushing water conduit unified with said ice-making water conduit, closely received in said gap at the top of said freezing plates so as to further and securely position said water supply unit with respect to said freezing plates, said flushing water conduit having means for spraying water therein downward onto said rear faces.
Claim 2
Dependent Claim 209 words
An ice-making machine comprising: a pair of approximately vertically extending, spaced apart, parallel freezing plates having respective opposing rear faces and having respective front faces opposite said rear faces, said front faces having vertically extending, horizontally spaced apart partitions projecting outwardly therefrom so as to provide between said partions portions of said front face defining freezer sections, said opposing rear faces being spaced apart by a predetermined gap; a cooling coil positioned between and secured to said rear faces in said gap; and a water supply unit on the top of said freezing plates, said water supply unit including an ice-making water conduit, water guide plates extending downwardly from said ice-making water conduit into respective spaces between adjacent ones of said partitions toward said freezing sections, so as to direct ice-making water from said ice-making water conduit onto the respective freezing sections and position said water supply unit with respect to said freezing plates, and a flushing water conduit unified with said ice-making water conduit, closely received in said gap at the top of said freezing plates so as to further and securely position said water supply unit with respect to said freezing plates, said flushing water conduit having means for spraying water therein downward onto said rear faces.
Claim 3
Dependent Claim 33 words
An apparatus as in claim 1, wherein said water supply unit further comprises inclined mounting plates fixed to said ice-making water conduit, said water guide plates being removably mounted to said mounting plates.
Claim 4
Dependent Claim 38 words
An apparatus as in claim 2, wherein said mounting plates extend downwardly and outwardly with respect to said ice-making water conduit and said front faces, and said water guide plates extend downwardly and inwardly toward said front faces.
Claim 5
Dependent Claim 19 words
An apparatus as in claim 1, wherein said ice-making water conduit and said flushing water conduit are integrally formed.
Claim 6
Dependent Claim 21 words
An apparatus as in claim 1, wherein said flushing water conduit is sandwiched between said rear faces of said freezing plates
Claim 7
Dependent Claim 64 words
An apparatus as in claim 1, wherein said gap has a constant horizontal width, said flushing water conduit having a generally rectangular vertical cross section and a horzontal width approximately equal to the horizontal width of said gap so that said flushing water conduit fits closely in said gap in contact with both of said rear faces at said top of said freezing plates.
