Description

DISPENSING APPARATUS AND METHOD FOR CONTROLLING THE SAME [0002]

The present invention relates to a dispensing apparatus and a control method thereof.

2. Description of the Related Art Generally, a dispensing device is a device in which when a user places a container such as a cup in the container, liquid such as water is automatically discharged to a container placed on the container, and the dispensing device is installed in a refrigerator and a water purifier.

For example, in the case of a refrigerator, the refrigerator is composed of a freezer compartment and a refrigerating compartment, and stores foods requiring various refrigerating compartments inside the refrigerator compartment.

In order to take food stored in the fridge, the fridge door must be opened.

When the door of the refrigerator compartment is opened, the cold air inside the refrigerator compartment flows out to the outside, the high temperature outdoor air enters the refrigerator compartment, the electric power consumption increases, and the foods being refrigerated are damaged by the high temperature outdoor air flowing into the refrigerator compartment.

1, in order to reduce the number of times of opening and closing the door 12 of the refrigerating compartment 10, when liquid such as water being stored in the refrigerating compartment 10 is taken out of the refrigerator compartment 10, The door 12 can be taken out to the outside through a dispenser or a dispenser without opening the door.

A container seating portion 16 capable of receiving a container 14 such as a cup for receiving the liquid to be dispensed and a liquid receiving portion 16 disposed on the container seating portion 16 are provided on the front surface of the door 12 of the normal refrigerating chamber 10. [ And a dispenser unit 20 provided with a liquid discharge port (not shown) for discharging the liquid.

In the refrigerating chamber 10, there is provided a storage tank for storing liquid, and an actuator such as a solenoid valve and a pump is provided. When the actuator is driven, the liquid stored in the storage tank is discharged through a liquid discharge port To the container 14 seated in the container seating portion 16 of the dispenser portion 20.

The liquid dispensing key 22 for instructing the dispensing of the liquid and the plurality of liquid dispensing height adjusting keys 30 for adjusting the height ratio of the liquid to be injected into the container 14 are provided on the upper part of the dispenser 20 .

The liquid input height adjusting key 30 is composed of a rising key 24 for raising the liquid input height ratio and a lowering key 26 for lowering the liquid input height ratio, It is possible.

On the other hand, the container seating portion 16 may be provided with a container detecting sensor (not shown) for detecting the presence or absence of the container 14 on the bottom surface on which the container 14 is seated.

A container detecting sensor (not shown) is constituted by, for example, a weight sensor and a push switch. When a liquid is introduced into the container 14 having a constant weight, the container 14 and the amount of the introduced liquid are added, 14, the liquid level of the liquid injected into the container 14 can be automatically detected.

The height of the container 14 and the height of the container 14 in the refrigerator or the water purifier provided with such a dispensing device are set so that only a proper amount of liquid is automatically supplied to the container 14 that is seated in the container seating portion 16. [ The height of the liquid injected into the liquid can be accurately determined.

To this end, there is known a technique of irradiating light to a container 14 that is seated in a container seating portion 16, receiving light reflected by the container 14 by a light receiving sensor, and measuring the height of the container 14.

However, when measuring the height of the container using the light, the container must be made of a material that reflects light, so that a container made of transparent glass can not be used.

In addition, since the light reflected from the container must be accurately reflected by the light receiving sensor, the shape of the container that can be used is extremely limited.

Also, in the above method, many errors occur in measuring the height of the container according to the intensity of the ambient light. For example, there is a limit to accurately measure the container height when the light reflectance of the container is low while natural light is present. On the contrary, a technique of measuring the height of the container by using ultrasonic waves is known. In the technique of measuring the height of the container using the ultrasonic waves, an ultrasonic wave output unit and an ultrasonic wave receiving unit are provided on a liquid discharge port, and an ultrasonic wave output unit outputs ultrasonic waves at predetermined time intervals. Ultrasonic waves are received by the ultrasonic receiver and the height of the container is measured.

The conventional dispensing device also requires that the user actuate the liquid dispensing key 22 after correctly placing the container 14 in the container seating position of the container seating portion 16 in order to effect liquid ejection into the container 14 , Which could be one of the factors that make it less convenient.
