Abstract

The present invention relates to a display device for detecting the remaining amount of a desired product for refrigerators. Conventionally, since there is no means for knowing the remaining amount of the desired product contained in each case, the consumer can put money in order to operate the product even though the finished product has run out. Even though there was a case in which there was no favorite item, it was cumbersome and inconvenient to see the case from time to time in order to know the amount remaining in each case, which wasted unnecessary time and effort.

The gist of the solution according to the present invention is a plurality of cases in which a predetermined preference item is put in, a drawer which draws out a certain amount from the case, a cup drawer which draws out a cup which can receive the preference goods drawn out by this drawer, etc. In the discharge device of the favorite product for a refrigerator comprising: a plurality of optical sensors attached to the outside of the case at regular intervals, characterized in that the display is electrically connected to the optical sensors are provided in the control panel.

The present invention relates to a display device for detecting the remaining amount of a favorite product installed in a refrigerator, and more particularly, by installing several optical sensors in a case of the favorite blender and displaying it on a control panel in front of the refrigerator, various materials can be easily identified. Therefore, the present invention relates to a display device for detecting the remaining amount of a desired symbol for a refrigerator, so that it can be replenished in a timely manner without having to check it frequently.

In general, vending machines are installed in public places or offices where many people come and go, and various kinds of beverages are provided, as well as coffee, tea, and cigarettes, which are favorite products.

Among these vending machines, coffee mixers, for example, a money detecting device for detecting and recognizing money, a plurality of cases for putting a predetermined preference product, a withdrawing device for withdrawing a certain amount from the case, and a favorite product with which the withdrawal device is withdrawn. And a cup taking out device for taking out a cup which can be received.

These vending machines, when you put money into the money inlet, detects and recognizes the money, the selection button of each sign corresponding to the currency is lit. When one of the favorite products is selected, the cup is first drawn out by the cup taking out device, and then the selected favorite products are sequentially discharged and mixed and diluted.

However, in the conventional vending machine, since there is no means for knowing the remaining amount of the sign product contained in each case, even though the sign product is exhausted, the receiver often does not come out even if the receiver puts money in and operates the sign product. There was a problem.

In addition, it was cumbersome and inconvenient to look at the case from time to time in order to know the amount remaining in each case, thereby wasting unnecessary time and effort.

The present invention has been researched and developed in order to solve the above-mentioned problems of the prior art, and by attaching several optical sensors to the outside of the case and providing a display electrically connected to the optical sensors to the control panel, It is an object of the present invention to provide a display device for detecting the remaining amount of a favorite item for a refrigerator, which enables the user to easily and easily know the remaining amount of a favorite item, and thus can replenish the desired item in time without having to check it frequently.

In order to achieve the above object, the present invention provides a cup extracting apparatus for extracting a plurality of cases into which a predetermined preference product is put, a drawing apparatus which draws out a certain amount from the case, and a cup which can receive the preference products drawn out by the drawing apparatus. In the discharge device of the favorite product for a refrigerator including a light source, a plurality of fixing pieces are formed on the outside of the case at regular intervals to attach an optical sensor, and a display electrically connected to the optical sensors is provided on the control panel. do.

Hereinafter, with reference to the accompanying drawings of the preferred embodiment of the present invention, the remaining amount detection display device for a favorite product for refrigerators as follows.

1 is a perspective view of a state in which the remaining amount detection display device is installed in a refrigerator according to the present invention, and FIG. 2 is a perspective view showing only main parts of the present invention.

As shown in the drawing, a favorite blender 14 is provided in the door 12 of the refrigerator 10, and the favorite blender 14 has a thin lower end of each case 16a-16c in front of the door 12. Only the protruding frame 18 is present.

The preference blender 14 has several cases 16a, 16b, and 16c arranged in a row in a shape of a light-receiving narrow shape having a wide peak and a lower end so as to accommodate each favorite.

On the side of the case 16a-16c, several optical sensors 20a-20c are formed to form several fixing pieces 17a-17c at regular intervals so as to measure the remaining amount of a favorite item. 20a-20c may be directly attached to the case 16a-16c, or may be provided by providing the separate sensor fixing plate in which the fixing piece was formed.

The frame 18 has a space portion 24 formed therein for putting the cup 22 on the front surface thereof, and several withdrawal buttons 26 are provided at the upper end thereof so as to withdraw a desired product in each case 16a-16c. It is installed.

On the upper side of the frame 18 is installed a display 28 electrically connected to the optical sensor 20a-20c so as to know the remaining amount of the article in the case (16a-16c), but on the control panel of the door 12 You can also install.

The whole quantity detection display device for the favorite product for the refrigerator according to the present invention configured as described above has the cup 22 in the space part 24 of the frame 18 constituting the favorite product mixer 14 from the front of the door 12. When the upper preference item is selected and the preference item takeout button 26 is pressed, the preference item in the cases 16a-16c is discharged.

In this way, the remaining quantity is reduced as the preference products in the cases 16a-16c are consumed. At this time, since the signal is blocked in the optical sensor 20a at the position where the preference product is reduced, only the optical sensors 20a and 20b up to the portion where the preference product is filled are displayed on the display 28 in the upper part of the frame 18.

Therefore, by looking at the degree of lighting on the display 28, it is possible to know the remaining amount of the article remaining in the case (16a-16c), and to see the state displayed on the display 28 can be replenished without having to check each of the internal symbol will be.

Therefore, unlike the prior art in which the remaining amount detection display device of the favorite product for the refrigerator according to the present invention cannot know the remaining amount of the favorite product, the remaining amount of the desired product can be simply and easily reduced by the display 28 connected to the optical sensors 20a-20c. Since it is also easy to understand, the convenience of use is provided.

As described above, according to the remaining amount detection display device of the sign product for refrigerators according to the present invention, the sign product remaining in the case by attaching several optical sensors to the outside of the case and providing a display electrically connected to the optical sensors on the control panel You can easily and easily know the remaining amount of, accordingly there is an effect that can be replenished in time without the need to check frequently.

Finally, although the present invention has been illustrated and described with respect to one specific embodiment, the present invention may be modified and changed in various ways without departing from the spirit or the field of the present invention provided by the following claims. I want to make sure that it belongs to the category.
