The present invention relates to a refrigerator having a body fat measurement function, and more particularly, to provide a body fat measurement function to a refrigerator so that the body fat can be measured at any time, and the height of the terminal for measuring the body fat is adjusted, irrespective of the height of the subject. The present invention relates to a refrigerator having a body fat measurement function having various additional functions, so that the measurement can be performed in a normal posture.

In general, a refrigerator is used to store or cool various kinds of foods or beverages in a frozen or refrigerated state for a long time. The refrigerator includes a freezer and a refrigerator, which are opened and closed by a front door, respectively. The compressor compresses the refrigerant at high temperature and high pressure to send it to the condenser, and then releases the heat of the refrigerant from the condenser and converts the liquid into a low temperature low pressure liquid refrigerant. The converted and sent to the cooler installed in the rear side of the freezer compartment, the refrigerant sent to the cooler passes through the coolant pipe of the cooler to a low pressure state to evaporate to lower the temperature of the freezer compartment and the freezer compartment.

These refrigerators are divided into upper and lower types having a freezer compartment at the top and a refrigerator compartment at the bottom, and a double door type having the freezer compartment at the left side and the refrigerating compartment at the right side. The trend is more preferred.

In addition, the utility of the refrigerator starts with the function of storing food for a long time, and now provides various functions such as supplying purified water and ice or providing a server or client function for networking functions including the Internet.

On the other hand, in recent years, as dietary life becomes more abundant and various types of instant foods increase, the interest in health increases due to an increase in the incidence of adult diseases, and together with the cause of the development of adult diseases as well as beauty There is a growing interest in the amount of fat in the body that is closely related.

As a result, a measuring device for measuring the amount of fat in the body has been widely developed and activated, and the body fat measuring device uses a bioelectrical impedance method mostly because of its low cost and harmlessness to the human body.

The bioelectrical impedance method flows weak sinusoidal alternating current to the human body, and if the body has a lot of moisture, electricity flows easily, and the electrical resistance is low. Because most of the body's water is contained in the muscles, and fat contains little water, this principle makes it possible to measure body fat as well as muscle mass.

In order to measure the amount of fat in the body by the bioelectrical impedance method, data such as height, weight, age, and gender of the subject, impedance value according to the composition ratio of the water, which is the conductor layer, and the fat, which is the insulating layer, are required. The two-terminal method, four-terminal method, and eight-terminal method are used depending on the number of terminals used.

Many medical diagnostic devices, such as a device for measuring body fat, are being developed and marketed at low cost so that they can be used at home, in addition to being used professionally in hospitals. However, medical diagnostic devices such as home body fat analyzers are used by the urgent need of some classes of users who are interested in a certain disease or already have a disease, and most others use these devices only as a preventive measure. By bothering them and neglecting their purchases, they had to purchase separately, even though they had difficulty visiting the hospital when needed or the opportunity to use it was not common.

Therefore, it is necessary to develop a refrigerator that can measure body fat, provide various functions, and contribute to the prevention of various adult diseases by providing diagnostic functions such as body fat measurement to refrigerators that are widely used in homes. .

The present invention is to solve the above-described problems, the object of the present invention is to provide a body fat measurement function in the refrigerator to measure the body fat at any time, by using a four-terminal method for body fat measurement uniformity and Increases accuracy and adjusts the height of the electrode to measure body fat so that it can be measured in a normal posture irrespective of the height of the subject, enabling accurate measurement, and information corresponding to body temperature, pulse measurement, and other measured body fat values It is to provide a refrigerator having a body fat measurement function to improve the convenience and utility of the measurement by providing a variety of additional functions, such as display and the like, and to help prevent adult diseases and improve health.
