Description

[Technical field]

[0001] The present invention relates to a sugar content meter, and more particularly to a sugar content meter having a temperature sensor installed at the center inside the lid, which directly measures the temperature of a sample and can obtain an accurate sugar content through temperature compensation based on more accurate temperature measurement. [Background technology]

[0002] Recently, as there has been much interest in health problems caused by food and drink intake, precise measurements of the components contained in food and drink have been carried out.

[0003] In the measurement of food and drink components, the sugar content is mainly measured by an optical method using refractive index. The optical method using refractive index can measure sugar content by measuring the difference in refractive index according to sugar content.

[0004] In order to reduce measurement errors caused by the temperature of the sample, such sugar content measuring devices generally have a temperature sensor installed inside the device body to measure the temperature of the sample and perform temperature compensation. However, in the case of the general sugar content measuring device described above, the temperature measuring device is installed inside the main body, and the temperature of the sample is not measured directly but indirectly, which means that an accurate temperature value cannot be obtained and it is difficult to perform more accurate temperature compensation, resulting in the problem that an accurate sugar content measurement cannot be obtained.

[0005] Therefore, there is a need to develop a sugar content measuring device that can obtain a more accurate temperature measurement value when measuring sugar content than when measuring temperature. [Prior art documents] [Patent documents]

[Brief description of the drawings]

[0013] [Figure 1] 1 is a perspective view showing a sugar content measuring device according to an embodiment of the present invention; [Diagram 2] 2 is a front view showing the sugar content measuring device of FIG. 1 with the cover portion closed, as viewed from the front. FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Before describing the embodiments of the present invention in detail, it should be made clear that the embodiments of the present invention are provided in order to fully explain the present invention to those skilled in the art.

[0015] Therefore, the scope of the present invention is not limited by the following examples and drawings.

[0016] In addition, the drawings in this specification are for the purpose of making the description by referring to the drawings clearer, and some parts are somewhat exaggerated, so there may be differences between the drawings shown in the present invention and the actual products.

[0017] The present invention will be described below with reference to the drawings. However, in order to simplify and clarify the description of the present invention, the sugar content measuring device will be generally described with reference to Fig. 1, and then the components of the sugar content measuring device will be specifically described with reference to Figs. 1 and 2.

[0018] FIG. 1 is a perspective view of a sugar content measuring device according to an embodiment of the present invention.

[0019] In one example of the sugar content measuring device 1 of the present invention, a temperature sensor 40 is provided at the center of the inside of the lid portion 30, and after a sample is dropped into the measuring portion 20, the lid portion 30 is covered so that the temperature sensor 40 directly measures the temperature of the sample, thereby obtaining a more accurate temperature measurement value.

[0020] In addition, a sugar content measuring device according to one example of the present invention can measure sugar content more accurately by performing temperature compensation on the refractive index measured by the measuring unit 20 using the temperature value measured by the temperature sensor 40.

[0021] Such a sugar content measuring device 1 includes a main body 10, a measuring unit 20, a cover unit 30, a temperature sensor 40, an operation unit 50, a calculation unit (not shown), and a display unit 60.

[0022] Hereinafter, the components of the sugar content measuring device and the effects of the components will be described in detail with reference to Figs.

[0023] The main body 10 is a frame in which the components of the sugar content measuring device described below are installed. A measuring unit 20, a cover unit 30, an operation unit 50, and a display unit 60 can be provided on the front surface of the main body 10.

[0024] A measuring unit 20 may be provided at an upper portion of the main body 10. The measuring unit 20 may include an optical sensor at a central portion. The optical sensor may measure the refractive index of a sample whose sugar content is to be measured.

[0025] As the optical sensor provided in the measuring unit 20, a prism can be used.

[0026] The cover 30 may be rotatably coupled to the upper side of the measuring unit 20. That is, the cover 30 is rotatably coupled to the upper end of the main body 10 while being on the upper side of the measuring unit 20, and can cover or open the measuring unit 20.

[0027] A temperature sensor 40 can be provided at the center inside the lid portion 30.

[0028] After a sample is applied to the measurement unit 20, when the measurement unit 20 rotates to cover the front surface of the measurement unit 20, the temperature sensor 40 can directly measure the temperature of the sample and transmit the measured sample temperature value to the calculation unit described below.

[0029] The temperature sensor 40 can generally be a laser sensor that can be used to measure temperature.

[0030] An operation unit 50 may be provided on the lower portion of the main body 10. The operation unit 50 may include a zero point adjustment button. 51 , power button 53 , measurement button 55 The configuration may include:

[0031] The operation unit 50 turns the sugar content meter of the present invention on / off via the power button, and can set the zero point for sugar content measurement by dripping tap water into the above-mentioned measurement unit 20 and then operating the zero point adjustment button.After setting the zero point, a sample can be dripped into the measurement unit 20, and then the lid unit 30 can be covered and the measurement button can be operated to measure the sugar content of the sample.

[0032] A calculation unit may be provided inside the main body 10. The calculation unit may receive the refractive index and temperature measured by the measurement unit 20 and the temperature sensor 40, respectively, and calculate the sugar content.

[0033] The calculation unit may further include a sugar content calculation module and a temperature compensation module.

[0034] The sugar content calculation module can calculate the sugar content of the sample from the refractive index measured by the measurement unit 20. That is, the measurement unit 20 measures the refractive index based on the refracted value when light emitted from a light source is transmitted through the sample, and transmits it to the sugar content calculation module of the calculation unit, and the sugar content calculation module can calculate the sugar content of the sample based on the refractive index measurement value measured by the measurement unit 20.

[0035] The temperature compensation module can use the temperature measured by the temperature sensor 40 to perform temperature compensation on the sugar content calculated by the sugar content calculation module described above.

[0036] Therefore, by performing temperature compensation using the temperature compensation module, it is possible to measure the sugar content of the sample more accurately.

[0037] A display unit 60 may be provided at the center of the main body 10. The display unit 60 may display the sugar content calculated by the sugar content calculation module and the temperature compensation module of the calculation unit, the refractive index measured by the measurement unit 20, and the temperature measurement value measured by the temperature sensor 40. Thus, a user using the sugar content meter may easily check the measurement value with the naked eye through the display unit 60.

[0038] Hereinafter, a sugar content measuring method using the sugar content measuring device of the present invention described above will be described in detail with reference to Figs.

[0039] A measurement method using the sugar content meter of the present invention includes a first step of setting a zero point, a second step of measuring the temperature of the sample, a third step of measuring the refractive index of the sample, a fourth step of calculating the sugar content from the measured refractive index of the sample, and a fifth step of performing temperature compensation on the calculated sugar content.

[0040] The first step is to set the zero point. That is, in this step, before measuring the sugar content, tap water is dripped onto the measuring unit 20, and then the cover unit 30 is rotated to cover the front of the measuring unit 20, and the zero point is set by operating the zero point adjustment button. Therefore, through this step, the sugar content can be measured more accurately. The second step is to measure the temperature of the sample.

[0041] In this step, after dropping a sample into the measurement unit 20, the cover unit 30 is rotated to cover the front of the measurement unit 20, and the laser of the temperature sensor 40 is allowed to penetrate the sample, thereby allowing the temperature of the sample to be measured directly.

[0042] In this step, the temperature sensor 40 installed in the center of the inside of the lid 30 directly measures the temperature of the sample, solving the problem that in conventional sugar content measuring devices, a temperature measuring device is installed inside the main body 10, and it is not possible to indirectly measure the temperature of the sample to obtain a more accurate temperature value, making it impossible to perform precise temperature compensation, and enabling the sugar content measuring device of the present invention to obtain a more accurate sugar content measurement value.

[0043] The third step is to measure the refractive index of the sample.

[0044] This step is a step in which light emitted from a light source is transmitted through a sample dropped on the measurement unit 20, and the refractive index is measured based on the refracted value.

[0045] In this step, the measured refractive index value can be transmitted to the sugar content calculation module of the calculation unit so that the sugar content calculation module can calculate the sugar content in the fourth step described below.

[0046] The fourth step is a step of calculating the sugar content from the refractive index of the sample measured by the measurement unit 20 through the above-mentioned third step.

[0047] That is, this step is a step in which the refractive index value measured in the above-mentioned third step is transmitted to a sugar content calculation module, and the sugar content is measured by performing a comparison operation with a preset value.

[0048] In this step, the calculated sugar content value can be transmitted to a temperature compensation module so that temperature compensation can be performed by the temperature compensation module in the fifth step described below. The fifth step is a step of performing temperature compensation on the sugar content calculated by the sugar content calculation module through the above-mentioned fourth step.

[0049] In other words, in this step, in order to reduce sugar content measurement errors caused by differences in sugar content values ​​due to temperature, the temperature compensation module of the calculation unit measures and receives an accurate temperature value from the temperature sensor 40, and performs temperature compensation on the sugar content calculated by the sugar content calculation module through the fourth step.

[0050] Therefore, by performing temperature compensation through this step, a more accurate sugar content value can be obtained.

[0051] Although the embodiments of the present invention have been described above with reference to the accompanying drawings, those skilled in the art will understand that the present invention can be embodied in various specific forms without changing the technical idea or essential features of the present invention. Therefore, it should be understood that the above-described embodiments are illustrative in all respects and are not limiting. [Explanation of symbols]
