Description

A storage-food display apparatus for a refrigerator and control methods the same}

The present invention relates to a storage food display device and method of the refrigerator, and more particularly, to a storage food display device and a control method using the same that can easily display the stored food of the refrigerator using a touch screen.

In order to maintain the freshness of internal foods according to the refrigerator products, a separate freshness maintaining room is provided to be selectively used by users. Various kinds of foods are stored in such a refrigerator, and the user has to go through the effort of opening and closing the refrigerator door every time to check this, because the user cannot remember the type of food that is built in. Identification of food stored in the refrigerator in this manner causes consumption of electrical energy due to opening and closing of the refrigerator door, and also causes waste of food because the food is decayed because the storage period is exceeded.

In order to solve this problem, FIG. 1 discloses a refrigerator capable of confirming stored foods from the outside.

As shown in FIG. 1, the conventional refrigerator controls a system capable of checking and monitoring information on types of food in the refrigerator outside the refrigerator, and records ROM, RAM, Inputting information about the internals to the microcomputer 10 including a timer, the microcomputer enable unit 30 to sequentially increase the address by supplying a pulse to the microcomputer 10, and the RAM of the microcomputer 10 And a data buffer unit 60 and an address decoder unit 70 for transmitting the internal unit information and address of the microcomputer 10 to the display unit 80. Doing.

From the above configuration, the conventional refrigerator has a toggle of the microcomputer enable unit 30 when the inside of the refrigerator stored in the RAM of the microcomputer 10 and the type, quantity, and storage period information of the inside of the refrigerator are to be checked from the outside of the refrigerator. While pressing the switch SW2, it is possible to check the kind of internal matter appearing on the display unit 80 and the like. That is, when the reset switch SW3 of the reset unit 40 is pressed to initialize the microcomputer 10 and the toggle switch SW2 is pressed, the addresses A0-A15 for the first address are transferred to the decoder 70. Decoded and input to the display unit 80, the data (D0-D7) of the corresponding address stored in the RAM is displayed on the display unit 80, the type, quantity, and retention period of the stored material through the buffer 60.

In this process, the conventional refrigerator puts the internals into the refrigerator and stores the information on the internals in the memory, so that the information on the internals can be shared with all the users of the refrigerator. It is possible to check the food inside the refrigerator from the outside of the refrigerator.

However, the conventional refrigerator displays a food group stored on the display unit 80 that is set in a state in which information on a plurality of food groups is input and stored.

That is, the conventional refrigerator uses a plurality of keys provided in the selection input unit 50 as shown in FIG. 2 to input information about stored foods into the RAM of the microcomputer 10. The selection input unit 50 includes an input key 50a, a direction key 50b, a confirmation key 50c, a deletion key 50d, and the like.

The input of a specific character through the selection input unit 50 configured as described above is performed through the following process. For example, when storing the "eggs" in the refrigerator compartment, when the input key 50a is selected, a text screen is displayed on the display unit 80. At this time, the displayed character screen is a character set in accordance with the region and country in which the refrigerator is used (Korean alphabet, or English alphabet) is displayed.

Thereafter, the user moves the cursor to the position of the desired character among the characters displayed on the display unit 80 using the direction key 50b, and then selects the confirmation key 50c to form a character "egg". If the character is incorrectly formed, the cursor is moved again using the direction key 50b, and then the deletion key 50d is selected to delete the character.

Therefore, in the conventional refrigerator, every time food is put into the refrigerator and stored, the stored food has to be recorded through the selection input unit 50. However, the recording at this time has a problem that it takes a lot of time to record, because the desired character must be formed, input, and stored according to a process of sequentially selecting characters.

That is, in the case of "egg", at least "a", "ㅖ", "ㄹ", "ㅏ", and "b" should be selected in sequence, and in selecting each character, the direction key 50b and the confirm key You must go through the process of entering (50c). If a typo occurs in the process, the delete key 50d must be used and the direction key 50b must be used, such as the use of several keys several times. This occurred.

In addition, since the display unit 80 provided in the refrigerator is configured as a small screen, difficulty in inputting and correcting characters is generated. These troublesome points did not lead to proper use of the function of displaying stored foods, resulting in problems such as leaving unnecessary functions.

In addition, since a conventional refrigerator must display appropriate characters on the display unit for each country or region to be used, the refrigerator at the time of shipment must be able to display characters for all languages, which is the capacity of the memory device for storing characters. At the same time, there was a problem of increasing the manufacturing cost.

Therefore, the present invention intends to propose a device that can easily input a character for the stored food as a method of drawing rather than directly inputting the character. In addition, the present invention is to propose a device that can display the food stored in the refrigerator, without the need for a separate control for the character display according to the type of language.

Accordingly, an object of the present invention is to provide a refrigerator storage food display apparatus that can display the stored food in the refrigerator by using a touch screen.

In addition, another object of the present invention to provide a refrigerator storage food information control method that can easily and easily input / delete the stored food information of the refrigerator using a touch screen.

Hereinafter, a refrigerator storage food display apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

Figure 3 is a block diagram for displaying the food stored in the refrigerator using a touch screen according to the present invention.

As shown, the touch screen display unit 125 is provided on the front of the refrigerator, allowing the user to easily write and delete inputs on the stored food. The touch screen controls the processor 105, which will be described later, which accesses software by an input means such as a finger or a special pen, generates a corresponding control signal, and processes coordinates of a touch signal applied to the display unit 125 described later. It is configured to receive. The touch screen includes an infrared light emitting unit 130 for converting and generating infrared rays from a control signal generated by the processor 105 and an infrared light receiving unit 135 for determining whether infrared light is generated from the infrared light emitting unit 130, and The touch screen display unit 125 indicates touch coordinates by the input means depending on the presence or absence of infrared rays.

In addition, as another embodiment of the touch screen, several resistance lines are arranged inside the display unit, and the control unit reads the touch position by changing the resistance value generated in the resistance line of the touched portion by the static electricity of the user's hand and displays the corresponding portion. It is also possible.

The processor 105 recognizes a character written by the user on the touch screen display unit 125 and performs control such as displaying data stored in the RAM 100 on the touch screen display unit 125 according to a user's request. . Therefore, a write buffer 115 and a read buffer 120 for buffering a write operation and a read operation are connected between the processor 105 and the touch screen display unit 125.

In addition, the processor 105 connects the ROM 110 storing the basic program for controlling the system and the RAM 100 storing various data about the information stored in the refrigerator through a data bus. Accordingly, the processor 105 controls the input, storage, and other operations of food through the touch screen display unit 125 based on the data stored in the ROM 110, and based on the data stored in the RAM 100. It will recognize the information of various stored foods stored in the refrigerator.

The following briefly describes an operation state of recognizing a touch signal according to a user's touch operation in the present invention having the above configuration.

When a predetermined control signal output from the processor 105 is supplied to the infrared light emitting unit 130 through the write buffer 115 and a touch operation occurs at a predetermined position of the touch screen display unit 125, the infrared light emitting unit 130 is provided. ) Converts the control signal of the processor 105 into infrared rays, and projects the infrared rays to the infrared light receiving unit 135 along the X and Y axes. At this time, any one of all the infrared data supplied by the user's touch operation is not projected on the infrared light receiving unit 135, thereby knowing that the touch operation is performed at a predetermined position on the display unit 125.

That is, when the infrared light emitted from the infrared light emitting unit 130 reaches all of the infrared light receiving units 135, it indicates that no input means is in contact with the display unit 125, and the infrared light is projected by the specific light receiving unit 135. When not reached, the display unit 125 recognizes that a touch operation is performed.

Next, a process of inputting and displaying information on food stored in the refrigerator using the touch screen will be described.

4 is an operation process diagram for the process of inputting and displaying the information of the stored food using the touch screen.

The processor 105 monitors whether to display the food stored in the refrigerator in a state where power is supplied according to a control program for displaying the stored food stored in the ROM 110 (step 200). In step 200, for example, when the user touches an arbitrary position of the touch screen display unit 125, it is possible to recognize that a display command for food stored in the refrigerator is input.

When the display command of the stored food is input in step 200, the processor 105 reads the refrigerator perspective view stored in the RAM 100 as shown in FIG. 5 and displays it on the touch screen display unit 125. At the same time, the food information stored in a separate address of the RAM according to each food holding room is read and the food information is displayed at the corresponding position together with the perspective view (step 205).

In the state in which the stored food information is displayed on the touch screen display unit 125 together with the refrigerator perspective view, the user touches a specific portion of the food holding room where the food put in step 200 is stored (step 210).

When the user touches the portion where the specific food holding chamber is shown in step 210, the processor 105 recognizes a setting address of the food holding chamber corresponding to the portion touched by the user. And it is to perform the operation to record the information on the food to be input in the set address.

In addition, the processor 105 displays an input screen as illustrated in FIG. 6 on the touch screen display unit 125 so that a task of recording food information may be performed (step 215).

When the input screen is displayed on the touch screen display unit 125 by the step 215, the user touches the "write key" to record the information about the food put into the refrigerator (step 220).

After the “write key” is touched in step 220, the processor 105 recognizes that the food information is to be written on the touch screen display unit 125, and then the touch position displayed on the touch screen display unit 125. Continuing to display until the next step 230 is performed to control the user's desired character is formed and displayed. That is, the user completes the character "egg" in step 225, and then forms a single character by displaying a touch position until the "storing key" in step 230 is selected.

In operation 225, when the “egg” is displayed on the touch screen display unit 125 and the user selects the “storage key” in operation 230, the processor 105 recognizes that the information of the food to be stored is completed. Then, the food information written on the touch screen display unit 125 is stored in the corresponding address of the food holding room selected in step 210 assigned to the RAM 100 (step 235).

When the storage operation in step 235 is completed, the display returns to the food position display screen shown in FIG. 5 to display the food stored in the refrigerator on the touch screen including the food information stored in step 235.

That is, the storage food information input of the refrigerator using the touch screen in the present invention, the food position display screen (Fig. 5) corresponding to the entire perspective view of the refrigerator is set in advance. And the address for each part of the refrigerator shown in FIG. 5 is allocated to the ram 100. FIG. Thereafter, when the user selects a specific location on the food location display screen shown in FIG. 5, the user recognizes the address of the selected specific location assigned to the RAM and stores the food information input at the address. It returns to the initial state again and shows the stored food information to the user as a perspective view of the refrigerator on the touch screen.

Similarly, even when the food is taken out of the refrigerator, the food holding chamber at the position where the food is taken out is selected on the food position display screen. When the input screen is displayed, the food information at the corresponding position can be deleted by touching the erase key and writing the food information to be erased.

As described above, the storage food display apparatus of the refrigerator and the control method using the same according to the present invention can easily record information on food stored in the refrigerator by using a touch screen. Therefore, the user can minimize the time spent for the function according to the recording of the stored food, and in particular, it has the effect of increasing the utilization of the function for recording and displaying the stored food.

In addition, by simplifying the display of a variety of languages using the touch screen, compared to the prior art, which has to set a specific character for each country, region, it is very easy to input information about the stored food, based on the input information It brings the effect that the user can receive.

Therefore, the present invention has the effect that it is possible to easily obtain information about the food stored in the refrigerator without receiving the functional and time restrictions on the character input.
