  • One of the convenient apparatus capable of discharging ice or water to the outside from a front surface of the freezing chamber door is commonly called a dispenser.
  • a refrigerator equipped with a dispenser is also mounted with an ice maker as an apparatus for producing ice to be supplied to the dispenser.
  • An ice maker for refrigerator generally includes a water supply source, an ice making container accommodating the water supplied from the water supply source and maintaining the water under freezing temperatures, an ice remover separately discharging ice cubes formed by the ice making container, and a storage for storing the separated ice cubes. A user may conveniently take out the ice cubes stored in the storage from outside.
  • the conventional ice maker is mounted with a water supply control valve for opening or closing a water supply hose connected from the water supply source to the ice making container, and is disposed with a controller for controllably opening the water supply control valve for a predetermined period of time.
  • the controller is operated in such a manner that a sufficient time is waited for the ice making from a time in which water supply to the ice making container is finished to allow the water supply control valve to close the water supply hose, and the ice remover separates the ice cubes from the ice making container when the ice cubes are completely formed.
  • the controller also performs a function of temporarily stopping making the ice cubes by monitoring if the ice cubes accommodated in the storage have reached a predetermined storage level.

Furthermore, even if the water supply source is a water reservoir separately provided with a refrigerator, the water pressure may vary in response to level of water accommodated in the water reservoir, such that the amount of water supplied to the ice making container may vary even if the water is supplied for the same period of time.
  • Another disadvantage is that the ejector, despite being equipped with a heater, may not properly remove the ice cubes if the ice cubes are too big, and if the ice cubes are too small, the ice cubes may warm up unnecessarily to melt with the ice cubes that are formed beforehand. In other words, different sizes of ice cubes could cause a user quality dissatisfaction of refrigerators.
  • all the tap water pipes in a house are branched out from one main pipe, and pressures of water supplied to water supply source of the ice maker may differ according to whether the tap water is used at a kitchen or not, so that sizes of ice cubes produced from a refrigerator installed at the same place and under the same condition may be varied.

  • An ice cube tray (100) may be disposed with a space for accommodating water by receiving the water from a water supply source (50), and serve to freeze the water by maintaining the water in freezing cold temperature.
  • the ice cube tray (100) may have a shape of an upwardly-opened vessel. Although the ice cube tray (100) has one space for accommodating the water in FIG.1, the shape is not limited to this type but the ice cube tray (100) may take other shapes for producing individual ice cubes by taking water in a plurality of individual concave grooves each arranged in parallel.
  • the water supply source (50) for supplying water to the ice cube tray (100) may be a tap water pipe outside of a refrigerator, a water reservoir of a water purifier separately installed from or integrally formed with the refrigerator, or a water storage tank installed inside the refrigerator.
  • a water supply hose (200) may be a pipe connected from the water supply source
  • a water supply control valve (300) may be disposed at the water supply hose (200) for opening or closing the water supply hose (200).
  • the water supply control valve (300) serves to open the water supply hose (200) to allow the water to flow into the water supply hose (200) or to close the water supply hose (200) for blocking off the water flow.
  • the water supply control valve (300) must be controlled in operation thereof by a controller (500. to be described later), such that it is preferable that the water supply control valve (300) include an electrically operated solenoid valve.
  • a water level sensor (400) disposed at the ice cube tray (100) may sense the level of water supplied to the ice cube tray (100) and convert the sensed level to an electrical signal and output the signal to the outside.
  • the water level sensor (400) may also con- tinuously sense the continuously changing water level inside the ice cube tray (100) and output a value thereof to the outside.
  • the controller (500) may receive the continuously rising water level value from the water level sensor (400) and if the value reaches a predetermined level, the water supply control valve (300) may close the water supply hose (200) to allow a predetermined amount of water to be supplied to the ice cube tray (100) at all times.
  • a water level sensor for continuously sensing the water level is well known, but a continuously sensing water level sensor is complicated and accurate in structure thereof and a construction of a controller for controlling the water level sensor is also complicated to make the practicality thereof deteriorate. Therefore, the water level sensor (400) preferably has a simple structure of sensing only whether the water level of the ice cube tray (100) has reached a predetermined level.
  • An exemplary water level sensor (400) may include a pair of electrodes (400a,
  • the pair of electrodes (400a, 400b), each being discretely disposed, may be connected to poles of an electric source (not shown) and one surface thereof may be exposed to an inner surface of the ice cube tray (100).

If the pair of electrodes (400a, 400b) is protruded from the inner surface of the ice cube tray (100), or buried into the ice cube tray (100), it may be difficult to separate the ice cubes formed inside the ice cube tray (100).
  • the controller (500) may perform necessary operations by receiving the electric signal from the water level sensor (400) to operationally control the water supply control valve (300).
  • the meaning that the controller (500) has received the electric signal is that the water level inside the ice cube tray (100) has risen up to a position of the water level sensor (400). Therefore, the water level sensor, more particularly, the pair of electrodes (400a, 400b) is preferably positioned adjacent to the upwardly opened surface of the ice cube tray (100), to be more specific, a highest position in the inner surface of the ice cube tray (100). If the electric signal is received from the water level sensor (400), the controller (500) may control the water level control valve (300) to allow the water supply hose (200).
  • the ice cube tray (100) may be then blocked of water supply, and it is possible to allow the ice cube tray (100) to receive a predetermined quantity of water at all times lest the ice cube tray (100) should be overflowed or short of water even if the water supply pressure of the water supply hose (200) varies.
  • the quantity of water supplied to the ice cube tray (100) is determined by the position of the water level sensor (400), such that change of position in the water level sensor (400) can adjust the quantity of water to be supplied to the ice cube tray (100).
  • FIG.2 is a schematic block diagram illustrating another exemplary implementation of an apparatus for supplying water to icemaker of refrigerator by fixed volume.
  • a water level sensor (410) is not located at a highest position of the ice cube tray (100) but at a position of an inner surface distanced from a floor surface of the ice cube tray (100), and accordingly, an operational process inside a controller (510) differs from that of the first exemplary implementation.
  • a water level sensor (410) may preferably include a pair of electrodes as the water level sensor (400) in the first exemplary implementation.
  • Other characteristics are also the same as those of the first exemplary implementation, such that same reference numerals are used to the same construction to allow deleting redundancy.
  • the water level sensor (410) is not located at the highest position of the ice cube tray (100), such that even if the water supply control valve (300) is opened to start the water supply to the ice cube tray (100), the water level sensor (410) may output an electric signal before the ice cube tray (100) is filled to the fullest level.
  • the controller (510) may perform a more complicated operation as compared with that of the first exemplary implementation. In other words, if an electric signal is received from the water level sensor (410), the controller (510) may calculate a time (tl) required from a time the water supply control valve (300) is opened to a time in which the electric signal is received from the water level sensor (410).
  • the controller (510) is pre-inputted with a height (hi) from the floor surface of the ice cube tray (100) to the water level sensor (410) and a height (h2) from the floor surface of the ice cube tray (100) to the opened surface of the ice cube tray (100), and the controller (510) may estimate a time (t2) of the water level inside the ice cube tray (100) reaching the total height (h2) of the ice cube tray (100), i.e., the time (t2) required for the ice cube tray (100) to reach the fullest level under the assumption that the water is supplied at the same speed as the time (tl) required for the water level inside the ice cube tray (100) to reach the height (hi).
  • An equation of estimating the time (t2) of the ice cube tray (100) being filled to the fullest level i.e., a time required for the ice cube tray (100) to reach the fullest level may vary according to the cubic shape of the ice cube tray (100) but the time (t2) of the ice cube tray (100) being filled with full water may be empirically obtained by repeated experiments, such that detailed explanation thereto will be omitted herein.
  • a target water level may be appropriately set up if necessary and a value thereof may be pre-inputted into the controller (510) to enable a target quantity of water to be supplied into the ice cube tray (100) accurately.
  • the reason the water level sensor (410) is not mounted at the uppermost position of the ice cube tray (100) unlike the first exemplary implementation is to prevent in advance the disadvantage of the ice cube tray being overfilled with the water by the influences, including a time taken for the controller which receives an electric signal outputted by the water level sensor to process the signal and operate the water supply control valve even if the water level sensor outputs the electric signal and a time taken for the water supply control valve to physically shut off the water supply hose. Particularly, there is a high probability of the water overflowing as the water supply pressure rises.
