Description

Refrigerator integrated body fat measuring device {An apparatus for detecting body fat intergrated with refigerator}

Refrigerators are used for the refrigeration and freezing storage of food, and can be said to be the most frequently used household appliances in general household life.

In addition, it is bulkier than other home appliances, and is located in the center of the kitchen, so the proportion of food in the household is large. For this reason, efforts have been made to increase the space utilization of the refrigerator or to expand its functions. For example, refrigerators with water purification systems, home bars, and deodorization systems are being introduced, and the refrigerator is used as a basic system of the home network in the home. In addition, products that provide functions to process food inventory management and ordering are being developed.

On the other hand, as the diet is getting better these days, obesity is increasing and interest in obesity is increasing.

The general public has also made an effort to maintain and manage weight properly by dieting and exercising, and thus, there is a demand for body fat measurement, a method of measuring obesity.

Obesity can not be judged by overweight alone. Since different body density and muscle composition ratios vary from person to person, an excessive weight to weight ratio may not be an accurate judgment, nor may it be an appropriate indicator for determining the risk of various side effects or diseases of the body caused by obesity.

That is, the criterion for determining obesity may be an important indicator for measuring the amount of body fat that can accurately determine the subcutaneous fat and the excess of the body fat component that is directly related to the diseases.

In addition to the standard weight method, which can be referred to as a reference value, the body fat mass measurement method includes a body mass index method, skin wrinkle thickness method, aquatic body density method, and a near-infrared device. Is being studied.

Although there are many methods, bioelectrical impedance analysis is known to be the most effective method to make the measurement cheaply and quickly without any hassle or aversion.

Impedance method consists of weak alternating current circuit between both ends of the body and measures body fat amount by measuring the change of impedance value according to the composition ratio of water, which is a conductor layer and fat, which is an insulating layer. .

DB = A-k '* W * Z / Ht ² -k''* W

Where DB is body density, A is constant, k is proportional constant, W is weight, Z is impedance, and Ht is height.

The last term considers the interference by weight, and can be expressed as the interference term of impedance in some cases. Using the body density obtained from the above formula, the body fat amount is expressed by the following formula.

% Body fat = (4.75 / DB-4.141) * 100

Devices using the impedance method mainly use the four-terminal method and the eight-terminal method, but the two-terminal method considering the simplicity is suitable for commercial use. For example, the Republic of Korea Patent Publication 2002-0026338 or USP 6,353,755 and the like introduces the application method for the two-terminal method. Body fat measurement method using the impedance method has existed only in the form of individual products or combined with the scale until now, the frequency of use is low, and it was cumbersome to buy a separate product.

It is an object of the present invention to improve the disadvantage of having to purchase a separate measuring equipment in the existing, to propose a body fat measuring device that can be easily used in consideration of the kitchen wire in the home.

1 is an illustration of a configuration for measuring body fat integrated in the refrigerator of the present invention. A basic information input unit 1 for inputting user ID, gender, height, weight information, etc. in advance, a data detector 2 for detecting a bioelectrical impedance signal generated by the human body through two parts of the body, and detecting the detected data A data processing unit 3 for processing, a controller 4 for calculating body fat using the detected data and basic information, a memory 5 for storing the calculated body fat value and the input basic information, and the calculated And a display section 6 for displaying body fat data managed from body fat and memory.

In the basic information input unit 1, a simple terminal input device for inputting ID, which is information for measuring subjects, and gender, height, and weight information indicating personal characteristics of each subject. Is composed. The input information is classified for each person to be measured and stored in the memory 5. The data detector 2 directly detects a human body impedance from a part of the body, and the body in contact with each of the two electrodes (electrode 1 and electrode 2). It is configured to generate a bioimpedance signal by the human body through the two parts of. The generated impedance signal is amplified and filtered by the data processor 3, AD converted, and the controller 4 calculates the body fat value by using the information stored in the memory 5. The calculated body fat information is accumulated in the memory 5 again and displayed to the user through the display unit 6.

The controller 4 may have a suitable communication protocol for communicating information with a refrigerator or an external device.

Since the memory 5 stores the body fat history classified by ID for each subject, the body fat trend may be checked and displayed by date or measurement time.

In addition, a timer function may be added to display a message regarding food recommendation or warning by body fat level or time of day.

2 relates to a form in which the body fat system is coupled to a refrigerator, and first of all, the characteristics of the door part of the refrigerator should be considered.

A typical home refrigerator has a structure in which a refrigerator compartment and a freezer compartment are divided into two sides (side by side method), a structure in which a freezer compartment is separated upwards (top mount method), and a structure in which a freezer compartment is separated below (bottom mount method). Divided into

The handle of each type of refrigerator may have a door handle or a grooved shape.

In the present invention, the body fat measuring apparatus of FIG. 1 is integrated into one part of the front door part of the refrigerator or integrated into the door handle part.

Fig. 3 shows an example of use in the case where the body fat measuring device is integrally installed in the door front part. The position of the body fat measuring device may be mounted by selecting any one point from a part of the front door part, particularly, a position convenient for the user to measure in an upright state. The user turns on the body fat analyzer, inputs ID, height, weight, and gender as necessary or checks the inputs, and then touches two fingers with two terminals to make a measurement.

4 is a diagram of a system in which a body fat analyzer is integrated into a door handle and an example of use thereof. When the body fat system is integrated into the door handle of the protruding refrigerator, the user can naturally select the body fat according to his / her choice during the normal operation of the refrigerator. That is, as shown in the figure, the two terminals are disposed to be spaced apart from each other up and down on one door handle. Refrigerator users usually open one door handle with one hand, but when measuring body fat, it is possible to turn on the power, hold the door handle so that the two hands do not touch each other, and touch both thumbs with the two terminals above and below.

If the door handle is formed horizontally, the input / output terminals of the body fat analyzer shown in Fig. 4 may be arranged horizontally instead of vertically.

As described above, the present invention integrates a two-terminal bioimpedance measurement system into one of the front door part or the door handle of the refrigerator, which is most closely related to nutrition intake, to prevent the obesity and body fat of family members. You can easily measure and manage the information.
