This embodiment is used when very small table space is available.

FIG. 12 shows another embodiment of the present invention, in which the upper portion 82 of the distribution section 70 of the distribution module 14 is connected above the sink as under an existing cabinet (alternatively mounted on a wall). ) By itself.

FIGS. 13 to 25 show the convertible dispenser 21 of the present invention.
0 shows a preferred embodiment. Dispenser 210 is similar to dispenser 10 described above, with the following difference:
Described below with reference to FIGS.

13 and 14 show the air vent arrangement of the dispenser 210. Dispenser 210 includes a lid 228 and a lid
Inlet 229 and exhaust 23 at front and rear of 228 respectively
Has zero. The cooling module 212 includes an air inlet 233 in an upper portion of the side wall 238.

When the cooling module 212 is attached to the distribution module 21, air flows through the air inlet 229 to the cooling module 212.
Flows through the condenser 246 and exits through the exhaust port 230. However, when the modules 212 and 214 are separated, the cooling module 212 is often located in a confined space, and the airflow flows directly from the outlet 230 to the inlet 229. This causes the compressor motor to run more frequently, wear more quickly, and raise the drink temperature.
Thus, in this situation, the air inlet 229 is covered by a plate 235 (eg, made of metal, wood or plastic), and air flows into the air inlet 233 and exits through the outlet 230. This arrangement of the plate 235 has been found to avoid the above problems.

Figures 15 and 15A show the condenser 246 (or condenser coil)
Shows a preferred arrangement of the cooling module 212, including a cooling fan 252, a cooling fan motor 253, and a separate stirrer motor 255. The fan and fan motor are mounted together as an integral, easily removable modular unit 257, including a bracket held in position by two screws 261. This arrangement allows the use of a larger condenser than in the dispenser 10.

By simply removing the two screws 261, the entire unit 257 is moved (after removal of the lid 228)
Easily slides upwards directly from the This also provides easy access to the agitator motor 25 and other components, including a transformer mounted adjacent the motor 255. This feature is because the dispenser 210 does not have a separate bonnet (or upper half of the housing) like many tabletop dispensers, so that when the lid is removed, access must be made to the top opening. ,is important. Thus, the dispenser 210 is small and compact, but the internal components are easily accessible, and the outer shell has a smooth, clean and continuous surface, providing a large advertising surface and a neat appearance.

FIGS. 16 and 17 show the water and syrup circuits for the dispenser 210 when the two modules are connected and disconnected. 16 and 17 show the cooling coil 271 in the soda line 273 downstream of the carbonator tank 258.
