In addition, the display device 200 may be formed not only on the door 101 but also on another position of the refrigerator 100.

4 is a view showing an embodiment in which the image of the display unit 241 is switched by the user's breath.

FIG. 4 shows an embodiment in which the display device 200 is mounted on the refrigerator 100. FIG.

As shown in FIG. 4 (a), when the user makes a bombardment with the display unit 241 of the display device 200, the screen of the display unit 241 can be switched. More specifically, when the sensor 300 senses the user's breath, the controller 280 controls the display unit 241 to display the second image 18 in a superimposed manner on the desktop of the display unit 241 having the first image 17 Can be controlled.

The first image 17 may be a desktop before the user blows it. The first image may be an image in which a plurality of icons capable of operating various functions of the refrigerator 100 are displayed. In addition, when the user selects the corresponding icon, it may mean a desktop on which an instruction corresponding to the icon is performed to provide related contents.

The sensor 300 senses the user's breath when the user breathes.

A sensor 300 that senses various stimuli may be used to sense the user's breath. For example, it can be micro-configured to sense a user's beeping sound. Preferably, the microphone is provided to sense a frequency of a sound field generated by a user.

In addition, the sensor 300 may include a humidity sensor 300 for detecting a change in humidity caused by the blowing, and a temperature sensor 300 for detecting an increase in the temperature of the air due to the blowing.

Meanwhile, the sensor 300 may be provided on one side of the display unit 241. The sensor 300 may be disposed at a lower portion of the display device 200 so that the sensor 300 may operate well even if a user is small.

4 (b), when the sensor 300 senses the user's breathing, the controller 280 superimposes a second image having a predetermined transparency on the first image of the display unit 241 Can be displayed.

In more detail, the controller 280 controls the first image 17 to be displayed in a state in which the second image 18 is slightly covered. In order to do so, the transparency of the second image 18 is adjusted by the controller 280.

In particular, the transparency of the second image 18 may be controlled to vary according to the number of times the user makes a breath, the time, or the period during which the breath is exerted.

For example, the control unit 280 may gradually decrease the transparency of the second image 18 when the user's time to attract the user increases. Here, images with high transparency are more transparent than images with low transparency.

As shown in FIG. 4 (b), the second image 18 is superimposed on the first image 17 with a predetermined transparency in an initial stage in which the user feels a bite. The transparency of the second image 18 is lowered by increasing the number of times or time that the user puts on the sound.

The controller 280 may display only the second image 18 on the display unit 241 as shown in FIG. 4 (c). That is, the transparency of the second image may gradually become closer to 0 as the time or the number of times the user makes a breath.

In other words, the display unit 241 is preferably displayed in the first image 17 so as to gradually change to the second image 18 by stimulation of the user's breathing.

In addition, it is only necessary to input simple "after" breaths without having to go through various complicated procedures. Therefore, since the screen of the display unit 241 can be controlled by a user's simple input, it is also easy to use.

On the other hand, the second image 18 can be set to be reflected on the display unit 241 in a natural reaction that can be intuitively predicted according to the user's breath.

More specifically, it is easy for a normal user to remind that the window is frozen when the window is opened. The control unit 280 may control the second image 18 so that a natural reaction, which is common in everyday life, can be implemented in the display.

That is, when the sensor 300 senses the user's breath, the controller 280 can display the second image 18 superimposed on the first image 17 on the window glass.

Also, the user can expect that the degree of frost on the windshield will increase as the blowing time increases. The control unit 280 may allow the emotional portion to be reflected on the display unit 241 as it is.

Accordingly, the control unit 280 can display an image in which the degree of frost on the window glass is increased according to the time or number of times the user bites.

According to one embodiment of the present invention, the second image 18 may be an image associated with weather information or seasonal information. To this end, the communication unit 210 may receive weather or seasonal information from an external server. The control unit 280 may display the second image 18 as an image corresponding to the received information.

For example, when the received season information is at least one of spring, summer, autumn, winter, wet season or dry season, the second image 18 may be an image that can symbolize or represent the season.

The image that can represent the seasonal information may be an image of a flower blooming in each season or an image of seasonal fruit. Also, it is preferable that the second image 18 be an image that can easily reflect typical seasons such as a cool sea or ice image in summer, an image of fallen leaves or autumn leaves in autumn, snow and frost in winter.

 Similarly, the weather information received by the communication unit 210 may be various information related to the weather, such as rain, snow, wind, cloudy, clear, typhoon, rainy season, or heat. The control unit 280 may display a second image 18 that may represent or represent the weather.

For example, the second image 18 on a rainy day may be an image of water droplets on the window. On snowy days, images with snow on the windows can be used.

It goes without saying that the type of the second image 18 corresponding to the season or weather information that the communication unit 210 can receive and classify is not limited to the above-described embodiment.

FIG. 5 is a diagram illustrating a state in which the user's touch input is displayed on the second image 18. The display device 200 may include a recognition unit 282 for recognizing a touch input of a user to the display unit 241.

That is, the recognition unit 282 senses the touch input of the user.

In some cases, a user can leave a picture or a letter with his or her finger on the window where the window is opened. This is because the condensed droplets are removed from the window and only the fingertip passes through it. The controller 280 preferably reflects the intuitive experience on the display device 200.

Accordingly, the controller 280 may control the second image 18 to display the touch input. In particular, according to an exemplary embodiment of the present invention, the controller 280 can display the second image 18 as if the second image 18 is transparent to the touch input area.

Since the second image is superimposed on the first image, when the user performs the touch input, the second image may be displayed such that the second image is deleted only in the touch input area of the second image superimposed on the first image. The deleted region in the second image may be represented such that the first image is projected or projected.

In other words, when the window is opened, the landscape outside the window is not visible. However, when the user touches the portion where the window has been touched with the finger, the condensed water drops are removed from the portion where the finger passes. When condensed water drops are removed, the outside of the window can be seen through the part where the finger passes. When the user touches the second image, the touch input portion is displayed transparently and the existing first image is displayed again in the transparent portion.

Instead of simply typing text, you can enter simple information directly with your finger. The image or character information drawn directly by the user's handwriting can effectively satisfy the desire of the users who want to transmit the emotion message.

In addition, the display unit 241, which has only the role of information transmission, can provide a feeling that the user can change to a canvas or a stationery by simple action. This can be a pleasure for users in terms of emotions.

In addition to this, the concept of drawing a letter or a picture on the screen after it has been intuitively experienced in real life can not only stimulate user's emotions, but also provide convenience and freshness.

The touch input may be an indirect touch or a direct touch.

6 is a diagram illustrating a display unit 241 according to an embodiment of the present invention. FIG. 6 (a) shows an existing desktop screen before the user starts blowing.

6B is a view showing a state in which the sensor 300 senses a user's sound when the user makes a sound and the controller 280 controls the display unit 241 to display a second image having a predetermined transparency Are overlapped.

Since the communication unit 210 can receive weather or seasonal information from an external server, the image with gender as shown in FIG. 6 can be displayed when weather information such as snowy weather and midwinter is received.

FIG. 6 (c) shows a step in which the user displays the contents of touch input to the second image after blowing sufficiently.

7 is a diagram illustrating a state in which a screen on which the user's touch input is displayed is transmitted to the external communication terminal 400. FIG.

The communication unit 210 can transmit the screen of the display unit 241 to the external communication terminal 400 when the control unit 280 displays the input information on the display unit 241 by the user's touch.

That is, a screen viewable on the display device 200 can be transmitted to the external communication terminal 400 connected through the network. The external communication terminal 400 may be a PC, a mobile phone, various electronic products in which the display device 200 can be installed, and the like.

The control unit 280 may display a receiver setting icon 261 on the display unit 241 for selecting an object to receive the screen of the display unit 241. [

The recipient setting icon 261 may be controlled to appear on the second image 18 when the user wants to transmit the screen of the display unit 241 to the external communication terminal 400.

When the recipient setting icon 261 is selected, the controller 280 can provide data storing the ID number of the external communication terminal 400, a telephone number, and the like. The user can select the recipient setting icon 261 and select a recipient to which the user-created memo is to be sent. Then, the communication unit 210 transmits the second image 18 on which the user's touch input is displayed to the receiver.

Therefore, it is possible to transmit emotional information to a receiver located far away from the display device 200. Therefore, the present invention can be used more advantageously than when the display device 200 is applied to a consumer electronic device or a communication terminal, which is commonly used by users.

For example, when the display device 200 is installed on the door of the refrigerator 100, the refrigerator 100 can be used to memorize necessary information through the display device 200. At this time, it is not necessary to have a difficult operation, but it is possible to accomplish the purpose only by a simple operation which draws a breath and draws a memo.

In addition, since the memo can be transmitted to any external communication terminal 400, the household appliance that has merely performed the refrigerating function can also perform the role of the communication terminal.

That is, the control unit 280 controls the display unit 241 to reflect the emotional and immediate reaction due to the simple act of breathing. When the recognition unit 282 recognizes the user's input, the control unit 280 provides the display unit 241 with a basis for displaying the touch input of the user.

In addition, the controller 280 can transmit the screen of the display unit 241 to the external communication terminal 400 by the user's selection. All of this is based on everyday life behavior, such as drawing pictures with fingers on the windowsill. Therefore, children, elderly people, intellectual disabilities, and the like who are unfamiliar with difficult device operation can easily use the present invention.
