Definitions

  • This invention relates to a water-cooled heat-accumulating type drink cooling system according to the first portion of claim 1, as it is used in cup-type automatic vending machines for refreshing drinks and dispensers for cold water or refreshing drinks.
  • a known water-cooled heat-accumulating type drink cooling system which has a cooling water tank filled with water and provided in the water therein with a cooler consisting of an evaporator for a refrigerator, a drink cooling coil formed at an intermediate portion of a drink supply pipe-line, and an electric water agitator, and which is adapted to cool a drink flowing in the drink cooling coil by operating the refrigerator with the water in the tank, which serves as a heat transfer medium, stirred by the electric agitator.
  • a layer of ice which is a so-called ice bank is kept formed at all times around the cooler disposed in the water tank. Accordingly, even when the operation of the refrigerator is interrupted, the cooling water in the tank can be maintained at a low temperature owing to the heat accumulated in the ice bank.
  • Such a method of momentarily increasing the drink cooling capacity is widely utilized.
  • Fig. 1 is a schematic diagram of such a water-cooled heat-accumulating type drink cooling system as described above.
  • reference numeral 1 denotes a drinking water source, such as city water, 2 a drinking water reservoir, 3 a drinking water supply pipe-line extended from the reservoir 2 and opened to a cup 5 placed on a vending stage 4, 6 a drinking water feed pump, 7 a drinking water supply valve provided at that portion of the pipe-line 3 which is close to a terminal end thereof, and 8 a drinking water supply control circuit.
  • a drinking water source such as city water
  • 2 a drinking water reservoir
  • 3 a drinking water supply pipe-line extended from the reservoir 2 and opened to a cup 5 placed on a vending stage 4
  • 6 a drinking water feed pump
  • 7 a drinking water supply valve provided at that portion of the pipe-line 3 which is close to a terminal end thereof
  • 8 a drinking water supply control circuit.
  • a drinking water cooling unit 9 consists of a cooling water tank 92 filled with water 91, a cooler 94 composed of an evaporator, which is disposed in the water in the tank 92, of a refrigerator 93, a water agitator 95, and a drinking water cooling coil 31 formed at an intermediate portion of the pipe-line 3 and immersed in the water in the tank 92 in such a manner that the coil 31 is spaced from the cooler 94.
  • Reference numeral 96 denotes a compressor motor of the refrigerator 93, 97 a drive motor for the agitator 95, and 98 an ice bank formed around the cooler 94.
  • the drinking water is stored in the reservoir 2 at all times. When a drinking water supply signal is given, the supply valve 7 is opened, and the pump 6 is operated at the same time to allow the drinking water cooled in the cooling coil 31 to be fed into the cup 5.
  • FIG. 2 An operation control circuit for the compressor motor 96 and the drive motor 97 in the conventional drink cooling system is shown in Fig. 2.
  • reference symbol TS 1 denotes a contact of a compressor control thermostat connected in series to the compressor motor 96.
  • a temperature-sensitive portion of the contact TS 1 is provided such that it is spaced from the cooler 94.
  • the temperature-sensitive portion of the contact TS 1 is covered therewith, so that the temperature of the ice is sensed by the temperature-sensitive portion of the contact TS 1 .
  • the control contact is opened to cause the compressor motor 96 to be stopped.
  • the control contact is closed to allow the compressor motor 96 to be actuated again, so that the operation of the refrigerator 93 is resumed.
  • the above-mentioned thermostat used as an operation control means for the compressor motor may be substituted by an electrode type ice sensor.
  • the drive motor 97 for the agitator is operated continuously while the drink cooling system is in operation, for the purpose of improving a total heat transfer coefficient. Accordingly, the water 91 in the tank 92 continues to be agitated.
  • Temperature characteristic curves a, b in the drawing represent the temperature of the water in the tank 92 and the temperature of the surface of the cooler 94, respectively.
  • the water is once over-cooled to a negative temperature To°C, which is lower than 0°C, i.e. a freezing point of water, during an initial stage of the formation of ice bank on the surface of the cooler 94.
  • To°C negative temperature
  • 0°C i.e. a freezing point of water
  • the agitator 95 is continuously operated as mentioned above to stir the water 91 in the tank 92 during the transition period in which ice begins to be formed on the surface of the cooler 94, the temperature of the water in every part of the interior of the tank becomes substantially equal to that of the cooler 94.
  • an over-cooling phenomenon occurs during an initial stage of formation of ice not only in the water 91 around the cooler 94 but also in the water 91 in the remaining portion of the interior of the tank 92.
  • the over-cooling temperature To°C in such a case is approximately -0.5°C to -2.0°C, though it varies depending upon the construction of the water tank, the .capacity of the refrigerator and the operational condition of the agitator.
  • a drink supply instruction is given at such time that small pieces of ice occur in the cooling coil 31, the pieces of ice flow with the drinking water in the pipe-line 3 to be gathered in narrow portions thereof, for example, an inner portion of the supply valve 7. As a result, the flow of drinking water is blocked or the drinking water is not supplied normally.
  • an agitator stopping means is provided adapted to sense a decrease in the temperature of the water in the tank to a level in the neighbourhood of +3°C and stop at once the agitator which has been in operation.
  • the agitator stopping means consists of a thermostat which has a control contact inserted in a drive motor circuit for the agitator.
  • the agitator is re-started as soon as the thermostat detects an increase of the water temperature in the tank to a value of about +6°C.
  • the invention as claimed is intended to remedy this drawback. It solves the problem of how to use the cooling system efficiently and nevertheless prevent small pieces of ice from being formed in the cooling coil.
  • the invention therefore provides that as soon as the agitator re-starting means has detected the formation of an ice bank it overrides the agitator stopping means, so that the agitator may operate independent of the operation state of the agitator stopping means. Thus the agitator may be re-started even if the temperature of the water is still at a level in the neighbourhood of 0°C. By that heat exchange efficiency of the cooling water and drink cooling coil, i.e. the drink cooling capacity of the drink cooling system can be increased.
  • Fig. 4 shows an operation control circuit of a cooling system.
  • a contact TS 2 of an agitator stopping thermostat is inserted in a power source circuit for the drive motor 97 for the agitator.
  • a temperature-sensitive portion S(TS 2 ) of the contact TS 2 for the thermostat is provided such that it is sufficiently spaced from the cooler 94.
  • the thermostat is adapted to sense a decrease in the temperature of the water in the tank 91 to a positive level T 2 , which is in the neighbourhood of its freezing point of 0°C, during a step of cooling the water by operating the cooler as shown in a time chart of operation thereof shown in Fig. 5.
  • this temperature level T 2 is reached, the contact TS 2 is opened at once.
  • FIG. 6 An operation control circuit of this embodiment, which employs a thermostat as an ice formation sensor, is shown in Fig. 6.
  • the circuit shown in Fig. 6 is provided, in addition to the contact TS 2 of the agitator stopping thermostat referred to in the previous description of the basic circuit shown in Fig. 4, with a b contact TS,' of the abovementioned compressor motor control thermostat, a control contact TS 3 of an agitator re-starting thermostat and a control contact X of a relay RV which is operated in accordance with a drink supply instruction.
  • These four control contacts are connected together in parallel to form an OR-circuit, which is inserted in an agitator motor circuit.
  • Temperature-sensitive portions S(TS1), S(TS 2 ), S(TS 3 ) of the contacts TS,, TS 2 , TS 3 of the above- mentioned thermostats are provided in alignment with one another with respect to the cooler 94.
  • characteristic curves designated by symbols c-g represent the distributions of temperature of the inner portion of a layer of ice.
  • the solid curves c, d, e represent the distributions of temperature in the inner portion of a layer of ice with respect to its thicknesses 1, II, III formed around the cooler 94 with the refrigerator in operation.
  • the broken curves f, g represent the distributions of temperature of the inner portion of the layer of ice with respect to its thicknesses II, III formed around the cooler 94 with the refrigerator not in operation.
  • the temperature of the surface of the cooler 94 is rapidly decreased to a negative temperature T 3 , which is sensed by the temperature-sensitive portion S(TS 3 ), which is in contact with the surface of the cooler 94, of the contact TS 3 of the agitator re-starting thermostat.
  • the control contact is closed to allow the agitator 95, the operation of which has been stopped by the contact TS 2 , to be started again.
  • the heat exchange efficiency of the cooling water and drink cooling coil i.e. the drink cooling capacity of the drink cooling system can be increased by re-starting the agitator 95 in the mentioned manner.
  • the thermostat contact TS 3 is adapted to be reopened at the temperature T 3 ' which is substantially equal to 0°C. The difference between the temperatures T 3 , T 3 ' constitutes a differential of the thermostat.
  • an ambient temperature of the temperature-sensitive portion S(TS 1 ) of the thermostat contact TS 1 is decreased to T 1 .
  • the thermostat contact TS 1 sensing this temperature is actuated to stop the compressor motor 96 and close the control contact TS,' of the motor circuit for the agitator (refer to Fig. 6).
  • an ambient temperature T 1 ' is sensed by the temperature-sensitive portion of the thermostat TS,, so that the contact thereof is shifted to allow the compressor motor 96 to be operated again.
  • the operation of the freezer or refrigerator is controlled by the thermostat contact TS 1 in such a manner that the thickness of ice can be maintained between the levels II, III unless the drink is supplied continuously to cause great variations in load.
  • the compressor motor 96 is stopped, the refrigerant ceases to flow in the cooler 94, so that the temperature of the outer surface thereof is increased to substantially 0°C.
  • the relay RV is adapted to receive a drink supply instruction and close its control contact X.
  • the agitator 95 is operated.
  • the operation of the contact X is not restricted by the operational conditions for the other thermostats. In other words, when a drink supply instruction is given even in a case where the temperature of the cooling water is decreased to a level in the neighbourhood of 0°C during the formation of ice to cause the agitator to be stopped by the agitator stopping thermostat contact TS 2 , the agitator is operated immediately in preference to the operation of the thermostat contact TS 2 .
  • Fig. 10 is a time chart of an operation of the operation control circuit shown in Fig. 6, which chart has been prepared on the basis of the actions thereof described above.
  • FIG. 8 Another embodiment of the present invention employing an electrode type ice sensor as an ice formation detecting means will be described with reference to Figs. 8 and 9.
  • Control contacts S i , S 2 shown in Fig. 8 play the same roles as the control contacts designated by symbols TS 1 , TS 3 in Fig. 6.
  • the control contacts S 1 , S 2 are opened and closed by an output signal from an electrode type ice sensor 10.
  • the ice sensor 10 consists of five electrodes designated by symbols A-E and arranged on one side of the cooler 94 in such a manner as shown in Fig. 9, and a detector circuit 12.
  • the electrodes A, B are reference electrodes constantly positioned in the water in the tank, and the electrodes C, D, E are ice sensor electrodes disposed in positions corresponding to the thicknesses III, II, I, respectively, of ice to be formed.
  • the detector circuit 12 consists of, for example, a bridge circuit for use in comparing the resistance between the electrodes A-B and the resistances between the electrodes A-C, A-D, A-E.
  • the detector circuit 12 is adapted to output a signal on the basis of the difference between the resistances measured and compared in the above-mentioned manner.
  • the specific resistance of water and that of ice differ from each other by a two-digit number. Accordingly, when no ice is formed on the surface of the cooler 94, the spaces between the electrodes A-B, A-E are occupied by water. In such a case, the resistances are in a balanced state, so that no signal is outputted from the circuit 12.
  • the balance between the resistances between the electrodes A-B, A-E is lost, and the formation of ice is sensed by the ice sensor to output a signal therefrom to allow the control contact S 2 to be closed.
  • control contact S is closed, and the compressor motor 96 continues to be operated.
  • the control contact S 1 is opened, so that the compressor motor 96 is stopped.
