Definitions

  • the present invention relates to a household appliance for the controlled supplying of cooled water or other beverage.
  • the present invention relates to a home refrigerator with an integrated cooled-drink dispenser for the controlled supplying of cooled water or other beverage at a given temperature, to which the following description refers purely by way of example.
  • cooled-drink dispenser built into the door to dispense, on command, cooled water at a temperature normally ranging between +5°C and +13°C.
  • the cooled-drink dispenser generally comprises a tank filled manually by the user with the water or other beverage to be dispensed; and a draw valve located in a recess formed in the outer surface of the refrigerator door.
  • the recess is designed to house a drinkable glass or similar container, and the draw valve is connected to the bottom of the tank by a connecting pipe, and is designed to only permit controlled outflow of the water or other beverage from the tank into the beverage dispensing recess underneath, when the recess is engaged by a drinkable glass or other container to receive the beverage.
  • the tank may be cooled by the cold air circulating inside the refrigerated compartment of the refrigerator, or by an auxiliary heat exchanger integrated in the heat-pump cooling circuit of the refrigerator.
  • the temperature of the water in the tank depends directly on the temperature maintained inside the refrigerated compartment by the cooling circuit of the refrigerator; whereas, in the second solution, the cooling circuit of the refrigerator is capable of maintaining the tank at a predetermined reference temperature, regardless and independently of the temperature maintained inside the refrigerated compartment/s of the refrigerator.
  • the cooling circuit of the cooled-drink dispenser may operate to maintain the tank at a given reference temperature user-selectable manually from a control panel on the refrigerator door.
  • the cooled-drink dispenser can only cater to the water temperature preference of one user, because the amount of water stored in the refrigerated tank (usually 2 or 3 litres) takes a long time to change temperature. Moreover, the cooling circuit of the cooled-drink dispenser fails to provide for rapidly increasing the temperature of the water stored in the tank, in the event the next user desires water at a slightly higher temperature than that set by the previous user.
  • number 1 indicates as a whole a household appliance for the controlled supplying of cooled water or other beverage.
  • household appliance 1 is a home refrigerator 1 incorporating a cooled-drink dispenser 2 for controlled supply of cooled drinkable water or other beverage at a given temperature above 0°C and preferably, though not necessarily, ranging between +5°C and +20°C.
  • refrigerator 1 comprises a rigid, self-supporting, substantially parallelepiped-shaped casing 3 having two superimposed refrigerated inner compartments 4 and 5, each of which is lined with thermally insulating material and communicates with the outside through a respective access opening formed in the vertical front wall of casing 3.
  • Refrigerator 1 also comprises two doors 6 and 7 hinged, one over the other, to the vertical front wall of casing 3 to rotate, about a preferably, though not necessarily, common vertical axis, to and from a closed position, in which each rests against the vertical front wall of casing 3 to close the access opening to, and hermetically seal from the outside, a respective refrigerated compartment 4, 5.
  • refrigerator 1 also comprises a heat-pump cooling circuit 8 (shown partly in Figure 1 ) which transfers heat from one fluid to another by exploiting the changes in state of an intermediate gas refrigerant subjected to a closed thermodynamic cycle, and which is designed to bring each refrigerated compartment 4, 5 to, and keep it at, a respective predetermined reference temperature normally lower than the outside temperature.
  • a heat-pump cooling circuit 8 shown partly in Figure 1 ) which transfers heat from one fluid to another by exploiting the changes in state of an intermediate gas refrigerant subjected to a closed thermodynamic cycle, and which is designed to bring each refrigerated compartment 4, 5 to, and keep it at, a respective predetermined reference temperature normally lower than the outside temperature.
  • the reference temperature is user-selectable within a predetermined temperature range.
  • heat-pump cooling circuit 8 is designed to keep refrigerated compartment 4 (i.e. the top compartment of the refrigerator) at a reference temperature ranging between +1°C and +10°C and preferably, though not necessarily, between +2°C and +8°C, so refrigerated compartment 4 is suitable for preserving non-freezable perishable foodstuffs; and to keep refrigerated compartment 5 (i.e. the bottom compartment of the refrigerator) at a lower reference temperature than refrigerated compartment 4 (i.e. below 0°C) and preferably, though not necessary, ranging between -2°C and -20°C, so refrigerated compartment 5 is suitable for freezing perishable foodstuffs and/or producing ice.
  • top refrigerated compartment 4 constitutes the "fresh-food compartment”
  • bottom refrigerated compartment 5 the "frozen-food compartment” of refrigerator 1.
  • cooled-drink dispenser 2 is integrated in the top door 6 of refrigerator 1, but may obviously be located on the vertical front wall of casing 3, beside top door 6 or bottom door 7 of refrigerator 1.
  • cooled-drink dispenser 2 comprises a tank 9 for temporarily storing drinkable water or any other beverage to be dispensed; and a draw valve 10, which is housed in a drink dispensing recess 6a formed in the outer surface of top door 6, is connected to tank 9 by a connecting pipe 11, and is designed to only permit controlled outflow of water or other beverage from tank 9 to recess 6a when recess 6a is engaged by a glass or other container to receive the water.
  • tank 9 is housed inside refrigerated compartment 4, i.e. the fresh-food compartment 4, of refrigerator 1, next to the fan that circulates the cold air in fresh-food compartment 4 through the evaporator of heat-pump cooling circuit 8, so that the cold air also flows over the outer surfaces of tank 9 to cool and keep the water or other beverage in tank 9 at the reference temperature of fresh-food compartment 4.
  • tank 9 may be housed inside an auxiliary compartment formed inside casing 3 or door 6, near recess 6a, and said auxiliary compartment may be cooled either by heat-pump cooling circuit 8, or by an independent cooling system such as a Peltier-effect cooling system.
  • cooled-drink dispenser 2 also comprises a second connecting pipe 12 permanently connecting tank 9 to a generic external source 13 of drinkable water or other beverage preferably, though not necessarily, at ambient temperature, so that tank 9 is always completely filled with drinkable water or other beverage; an electric supply pump 14, along connecting pipe 12, for feeding drinkable water or other beverage, on command, along connecting pipe 12 at a given flow rate; a temperature detecting device 15 for determining the instantaneous temperature of the drinkable water or other beverage flowing along connecting pipe 12; and preferably, though not necessarily, an on-off valve 16 for isolating connecting pipe 12, on command, from source 13 to cut off flow of the drinkable water or other beverage.
  • on-off valve 16 and temperature detecting device 15 are located upstream and downstream from pump 14, respectively; and source 13 is defined by the drinkable water circuit of the building in which refrigerator 1 is located.
  • source 13 may also consist of a common pressurized container storing a given quantity of drinkable water or other beverage.
  • cooled-drink dispenser 2 along connecting pipe 12, downstream from temperature detecting device 15 and upstream from tank 9, cooled-drink dispenser 2 also comprises an electrically operated hydraulic distributor 17 designed, on command, to channel a given part of the drinkable water or other beverage flowing along connecting pipe 12, to an auxiliary connecting pipe 18 which bypasses tank 9 and terminates directly inside connecting pipe 11, so as to divert at least part of the ambient-temperature water or other beverage from source 13 directly to draw valve 10.
  • auxiliary connecting pipe 18 is branch connected to connecting pipe 11, and hydraulic distributor 17 consists of a three-way electrovalve 17 having the inlet connected to connecting pipe 12, and the two outlets connected respectively to tank 9 and auxiliary connecting pipe 18, so that all the drinkable water or other beverage flowing along connecting pipe 12 can be channeled, on command, to tank 9 or auxiliary connecting pipe 18.
  • cooled-drink dispenser 2 also comprises an electronic central control unit 19, which controls hydraulic distributor 17 on the basis of signals from temperature detecting device 15, and the selected temperature of the drinkable water or other beverage to be supplied by cooled-drink dispenser 2; and a user control panel 20, by which to communicate to central control unit 19 the selected temperature T 0 of the drinkable water or other beverage to be supplied by cooled-drink dispenser 2.
  • detecting device 15 measures the instantaneous current temperature T 1 of the incoming drinkable water or other beverage from source 13; and control unit 19 calculates the estimated current temperature T 2 of the drinkable water or other beverage in tank 9 on the basis of a tank cooling system mathematical model, which is specific for each model of refrigerator 1, and which describes the temperature T 2 pattern of the drinkable water or other beverage in tank 9 as a function of the time lapsed since draw-off of the last drink, and as a function of the temperature and amount of ambient-temperature drinkable water or other beverage fed into tank 9 from source 13 when drawing off the last drink, taking into account the real cooling capacity of the environment surrounding tank 9 (i.e. the tank cooling system formed, in the example shown, by fresh-food compartment 4 and heat-pump cooling circuit 8).
  • the tank cooling system formed, in the example shown, by fresh-food compartment 4 and heat-pump cooling circuit 8
  • control unit 19 calculates the estimated current temperature T 2 of the drinkable water or other beverage in tank 9 on the basis of a given number of experimentally-obtained work curves stored in control unit 19, and which describe the patterns of temperature T 2 as a function of the time lapsed since draw-off of the last drink ( Figure 4 ); and the patterns of temperature T 2 as a function of the temperature T 1 and of the amount M x of cold water or other beverage last drawn off from tank 9 ( Figure 3 ).
  • the temperature T 2 of the water or other beverage stored in tank 9 rises to a value T 2 ' which depends on the amount M x of ambient-temperature water or other beverage from source 13 that enters in tank 9 to replace the cold water or other beverage drawn off from tank 9, and on the actual temperature T 1 of the ambient-temperature water or other beverage arriving from source 13.
  • control unit 19 can calculate, immediately after having dispensed a drink, the estimated current temperature T 2 ' of the drinkable water or other beverage in tank 9 on the basis of the amount M x of cold water or other beverage drawn off from tank 9, and of the actual temperature T 1 of the water or other beverage entering in tank 9 from source 13.
  • the time which cold water or other beverage stored in tank 9 takes to return to the given minimum temperature of the environment surrounding tank 9 depends on the cooling capacity of the environment surrounding tank 9 (i.e. the tank cooling system formed, in the example shown, by fresh-food compartment 4 and heat-pump cooling circuit 8), and it is a function of the temperature T 2 ' of the drinkable water or other beverage stored in tank 9 immediately after having dispensed last drink, and of the time lapsed since the supply of the last drink.
  • control unit 19 can calculate the estimated current temperature T 2 of the drinkable water or other beverage in tank 9 when a new drink is requested, on the basis of lapsed time since draw-off of the last drink.
  • electronic central control unit 19 implementing the calculating method referred below, is able to determine the amount M 1 of drinkable water or other beverage at temperature T 1 from source 13, and the amount M 2 of cold water or other beverage at temperature T 2 from tank 9, to be mixed to obtain the drinkable water or other beverage at the user-selected temperature T 0 from draw valve 10; and then to drive hydraulic distributor 17 to selectively split between tank 9 and auxiliary connecting pipe 18 the drinkable water or other beverage flowing along connecting pipe 12, so as to channel to draw valve 10 the calculated amount M 1 of drinkable water or other beverage at temperature T 1 , and the calculated amount M 2 of drinkable water or other beverage at estimated temperature T 2 .
  • electronic central control unit 19 drives, or rather quickly switches, three-way electrovalve 17 so that the drinkable water or other beverage flowing along connecting pipe 12 is selectively channeled to tank 9 or directly to draw valve 10 according to the calculated amounts M 1 and M 2 .
  • the flow rate of the water or other beverage along connecting pipe 12 being known and constant
  • the amount M 2 of drinkable water or other beverage channeled to tank 9 is a direct function of the time interval in which hydraulic distributor 17 connects pipe 12 to tank 9
  • the amount M 1 of drinkable water or other beverage channeled directly to draw valve 10 is a direct function of the time interval in which hydraulic distributor 17 connects pipe 12 to auxiliary connecting pipe 18.
  • electronic central control unit 19 determines the current temperature T 1 of the drinkable water or other beverage from source 13 via temperature detecting device 15, and calculates, using the tank cooling system mathematical model, the estimated current temperature T 2 of the drinkable water or other beverage in tank 9 on the basis of the time lapsed since draw-off of last drink by cooled-drink dispenser 2; of the temperature T 1 of the drinkable water or other beverage from source 13 at the time of last drink draw-off; and of the amount M x of cold water or other beverage drawn from tank 9 during draw-off of the last drink by cooled-drink dispenser 2.
  • electronic central control unit 19 activates supply pump 14 and regulates the switching time of three-way electrovalve 17 so that the calculated amounts M 1 and M 2 of drinkable water or other beverage are channeled to auxiliary connecting pipe 18 and tank 9 respectively.
  • auxiliary connecting pipe 18 is connected directly to draw valve 10, and the ambient-temperature water or other beverage channeled into tank 9 by hydraulic distributor 17 feeds out of tank 9 an equal amount of cold water or other beverage via connecting pipe 11, electronic central control unit 19 regulates the switching time of three-way electrovalve 17 to channel the calculated amounts M 1 and M 2 of drinkable water or other beverage to draw valve 10, and so supply the user with cooled water or other beverage at user-selected temperature T 0 .
