The user can also obtain the operating condition information of domestic appliance 100 through the light that lamp strip 50 sent, has increased user and domestic appliance 100's interactive mode, is favorable to promoting user experience.

In the related art, a TFT (Thin Film Transistor) touch screen is used on a panel by a household appliance to display related contents, but the TFT touch screen has a poor display effect, which is mainly reflected in that a viewing angle is too narrow, brightness is insufficient, and each pixel on the TFT touch screen works no matter a displayed image is black or other colors because the TFT touch screen belongs to one type of liquid crystal screen, so that a control board correspondingly controlling the TFT touch screen needs to meet the requirement of constantly controlling all pixels to work when selecting a type, and the control board needs to be configured at a high cost because the requirement of the control board is high.

In the household appliance 100 according to the embodiment of the present invention, the OLED module 32 may be used to display the first content, and the portion of the OLED module 32 that does not display the first content remains in a non-light emitting state, that is, the pixel point that does not display the first content may remain in a non-operating state, so when the control unit 40 that controls the OLED module 32 is selected, the control unit 40 does not need to constantly control all the pixel points to operate, the requirement on the control unit 40 is low, and the control unit 40 with a low price may be selected, so that the cost may be saved by using the OLED module 32 as compared to the TFT.

Specifically, the home appliance 100 may be used for the home appliance 100 for displaying contents of an operation menu, an operation state, and the like of the home appliance 100. The household appliance 100 may be a refrigerator, an oven, a microwave oven, an electric steamer, a steaming oven, a micro-steaming oven, a washing machine, a dishwasher, etc., and the embodiment of the present invention is described by taking the example that the household appliance 100 is the micro-steaming oven, but the specific kind of the household appliance 100 is not limited.

The OLED module 32 may include an OLED device having a display function, which has higher display brightness, wider visible range, and relatively lower power consumption.

The LED module 34 may include an LED device having a display function, and the LED device displays contents by controlling on and off of the light emitting diode, so that the LED module is suitable for displaying simple contents, and the manufacturing cost, power consumption, and the like of the LED device are low. The LED module 34 may be fabricated in the form of an LED nixie tube.

The light bar 50 may include LED devices capable of emitting light of different colors, and different operation conditions of the household appliance can be represented by different display effects. Specifically, the light bar 50 may be a bar-shaped light array composed of LED lights capable of emitting lights of different colors.

In the embodiment shown in fig. 1, the panel 20 is not designed to be perforated, and the panel 20 covers the entire touch display screen 30. It is understood that in other embodiments, the panel 20 may also be formed with through holes where the touch display screen 30 is mounted. The control part 40 may be disposed under the touch display screen 30.

The operation instructions acquired by the touch screen 36 may include instructions triggered by touch positions and touch gestures to implement certain logic operations. Both touch location and touch gestures may be triggered by a user on the panel 20 or touch screen 36.

The control unit 40 can acquire the operation instruction acquired by the touch panel 36, and the control unit 40 changes the first content and the second content according to the touch position and the touch gesture of the user. For example, in the household electrical appliance 100, a user touches a portion of the panel 20 corresponding to the touch screen 36 to trigger an operation instruction, so as to change the first content and the second content, for example, change parameters such as a function mode, a temperature, a time, and a power of the household electrical appliance 100.

It should be noted that, in the above operation instruction, the first content and the second content may be changed, and accordingly, the operating state of the household appliance 100 may also be controlled, so that the first content and the second content are associated with the operating state of the household appliance 100, and the operating state of the household appliance 100 is constantly reflected on the first content and the second content.

In some embodiments, the household appliance 100 includes a voice module 70, and the control part 70 is configured to control the voice module 70 to broadcast voice information according to an operation condition of the household appliance 100. Therefore, the household appliance 100 can interact with the user in a voice broadcasting mode, and a mode for acquiring the running condition of the household appliance 100 by the user is increased.

Specifically, the voice module 70 may be provided below the panel 20. The voice module 70 receives a voice broadcasting instruction sent by the control part, and broadcasts voice related to the first content and the second content according to the voice broadcasting instruction, so as to prompt the current working state of the household appliance 100 and prompt the next operation guide. For example, when the household electrical appliance 100 is a micro-steaming oven, after the micro-steaming oven reaches the preheating temperature, the voice module 70 broadcasts voices such as "preheating temperature is reached" and "please open the oven door to put food in". After food is put in and the oven door is closed, the voice module 70 can broadcast a voice of "please press the start key to continue cooking". After the micro-steamer finishes cooking, the voice module 70 can broadcast "cooked, please enjoy" voice ".

In setting the adjustable parameter, the voice module 70 reports "maximum temperature", "maximum time", or "maximum power" voice when the adjustable parameter is adjusted to the maximum value. Upon switching the micro-steaming oven to the grill mode, the voice module 70 may broadcast a "grill mode" voice. After the user sets the cooking parameters, the control unit 40 determines the gesture operation of the user on the touch panel 36, and controls the voice module 70 to voice-prompt "start cooking" or "continue cooking".

Referring to fig. 1, in some embodiments, the household appliance 100 includes a circuit board 60. The control portion 40 is disposed on the circuit board 60, and the OLED module 32, the LED module 34, and the light bar 50 are disposed between the touch screen 36 and the circuit board 60.

Specifically, with continued reference to fig. 1, the OLED module 32 may be disposed on the left side of the LED module, and the light bar 50 may be disposed on the front side of the touch display screen 30. It is understood that in other embodiments, the light bar 50 can be disposed at other positions, such as embedded in the surface of the panel 20.

Referring to fig. 1, in some embodiments, the OLED module 32 is connected to a first connector, the LED module 34 is connected to a second connector, and the touch screen 36 is connected to a third connector. The circuit board 60 is provided with a fourth connector 62, a fifth connector 64 and a sixth connector 66. The first connector is connected to the fourth connector 62, the second connector is connected to the fifth connector 64, and the third connector is connected to the sixth connector 66.

In this manner, circuit board 60 and OLED module 32 are connected by first and fourth connectors 62, circuit board 60 and LED module 34 are connected by second and fifth connectors 54, and circuit board 60 and touch screen 36 are connected by third and sixth connectors 56, facilitating installation and maintenance of OLED module 32, LED module 34 and touch screen 36.

Specifically, the first connector and the fourth connector 62, the second connector and the fifth connector 64, and the third connector and the sixth connector 66 may be connected by the flexible circuit board 80. The flexible circuit board 80 is light, thin and easy to bend, so that the integration level of the household appliance 100 can be further improved. Of course, in other embodiments, the first connector and the fourth connector 62, the second connector and the fifth connector 64, and the third connector and the sixth connector 66 may be connected by other devices that can achieve the connection function, and the connection is not limited herein.

Referring to fig. 1, in some embodiments, the number of LED modules 34 is two. Wherein the second content displayed by one LED module 34 is different from the second content displayed by another LED module 34.

Thus, the requirement of the kind of the second content, that is, more kinds of the second content can be displayed, and the display content of the home appliance 100 is enriched. For example, the second content may include temperature, time, power, and gear content. For another example, when the household appliance 100 is a micro-steamer, one of the LED modules 34 may display temperature and the other LED module 34 may display time. Or when the household appliance 100 is an induction cooker, one of the LED modules 34 may display power and the other LED module 34 may display time. Or when the household appliance 100 is a refrigerator, one of the LED modules 34 may display the gear position and the other LED module 34 may display the temperature.

Of course, in other embodiments, the number of LED modules 34 may be other, and may be determined according to the actual needs. A greater number of LED modules 34 may display more second content as the structure of the household appliance 100 allows.

Specifically, in the embodiment of the present invention, the arrangement of the OLED module 52 and the two LED modules 34 may be flexibly configured, may be arranged according to the size and shape of the panel 20, and may also optimize the appearance of the household appliance 100 through the flexible arrangement of the OLED module 52 and the LED modules 34. Therefore, the touch display screen 30 according to the embodiment of the present invention has a strong applicability, and particularly, when the display structures or sizes of the household appliances 100 of different models need to be changed, the touch display screen 30 can be adapted to the household appliances 100 of different models by flexibly arranging the OLED module 32 and the LED module 34, which is beneficial to saving the time cost in the development process of the household appliance 100 product and reducing the development cost of the display structure re-mold design.

Referring to fig. 3 to 5, fig. 3 to 5 respectively show three different arrangement forms of the OLED module 32, the LED module 34 and the light bar 50 on the household appliance 100, the OLED module 32 and the LED module 34 can be flexibly arranged according to the structure of the panel 20, the household appliance 100 can be adapted to different types of household appliances 100, and the universality of the household appliance 100 is improved. Of course, the OLED module 32, the LED module 34 and the light bar 50 are not limited to the arrangement shown in fig. 3 to 5, and can be flexibly changed according to actual needs, which is not limited herein.

More, the distance between the OLED module 32 and the two LED modules 34 can be flexibly changed, and when the distance is larger, the display portion of the household appliance 100 can be made to have a larger size in appearance, and the aesthetic appearance of the household appliance 100 is improved. When having a smaller pitch, the home appliance 100 can be made more compact.

In some embodiments, the first content includes a function menu and the second content includes adjustable parameters associated with the function menu.

Therefore, the OLED module 32 has a good display effect, high brightness and a large viewing angle, and can better display complex graphics and characters such as a function menu; the adjustable parameters are simple in content, the displayed content and the position are basically fixed, and the LED module 34 is used for displaying, so that the size of the OLED module 32 is reduced, and the cost is saved.

In particular, the function menu may generally include a plurality of functions, for example, for a micro-steamer, the function menu includes microwave, steam, and grill functions. Moreover, each function generally has corresponding adjustable parameters, and the adjustable parameters may include parameters such as temperature, time, power, and the like. The function menu generally has more characters or graphs, so that each function can be understood by the user more intuitively, and the function menu can correspond to a larger user group, and particularly, the vivid graph can improve the use experience of the user group with character recognition obstacles. Therefore, the OLED module 32 with better display effect is used to display the function menu. The parameters such as temperature, time and power in the adjustable parameters need to be displayed for a long time, and the displayed contents are mainly numbers, so that a relatively fixed display position can be provided. Therefore, the LED module 34 can be used to display the adjustable parameter, which can prevent all the first content and the second content from being displayed by the OLED module 32, and the second content with simpler content is allocated to the LED module 34 to be displayed, which can reduce the size of the OLED module 32, and the OLED module 32 with the same size is more expensive than the LED module 34, and the use of the LED module 34 can save the cost.

The first and second contents are related, for example, by switching a function menu to a microwave mode on the OLED module 32, the LED module 34 will correspond to default values of parameters for displaying the temperature, time and power of the microwave, and the parameters can be adjusted in subsequent operations.

In some embodiments, the touch screen 36 is a capacitive screen. The capacitive screen has the advantages of high response speed, high precision and long service life, and is favorable for improving user experience.

Of course, in other embodiments, the touch screen 36 may also be other components capable of achieving touch effect, such as a resistive screen, which is not limited herein.

In some embodiments, the household appliance 100 is provided with at least two cooking modes, the operation condition of the household appliance 100 includes one cooking mode, and the control part 40 is configured to control the light color of the light bar 50 according to the cooking mode. In this way, the user can know the cooking mode of the household appliance 100 through the light of different colors emitted by the light bar 50.

Specifically, the following describes the light colors of the light bars 50 of the household appliance 100 in different cooking modes, taking the household appliance 100 of the present embodiment as an example of a micro-steaming oven. The micro-steaming oven may include at least three cooking modes, microwave, steam, and grill. In the microwave mode, the light bar 50 displays blue light. In the steam mode, the light bar 50 displays white light. In the grill mode, the light bar 50 displays orange light.

It is understood that in other embodiments, the household appliance 100 may further include other cooking modes, and different cooking modes may correspond to different colors of the light bar 50.

In some embodiments, the household appliance 100 is provided with at least two states of the household appliance 100, the operation condition of the household appliance 100 includes one state of the household appliance 100, and the control part 40 is configured to control the display mode of the light bar 50 according to the state of the household appliance 100.

Thus, the display of the light bar 50 can feed back the state of the household appliance 100 to the user, and the manner for the user to acquire the operation condition of the household appliance 100 is increased.

In some embodiments, the states of the home appliance 100 include a set parameter state, an operation state, a cooking end state, a power saving state, and a standby state; in the parameter setting state, the control part 40 is used for controlling the light bar 50 to display normally bright; in the operating state, the control part 40 is used for controlling the light bar 50 to display the cooking progress; in the cooking end state, the control part 40 is used for controlling the light bar 50 to flash and display; in the power saving state, the control part 40 is used for controlling the light bar 50 to be turned off; in the standby state, the control part 40 is used for controlling the light bar 50 to dynamically display a plurality of colors.

In this way, the control part 40 controls different display effects of the light bar 50, and feeds back the operation condition of the household appliance 100 to the user through the light bar 50, thereby increasing the way for the user to obtain the operation condition of the household appliance 100.

It is noted that the operation condition of the household appliance 100 may include any state after the household appliance 100 is powered on and the switch of the household appliance 100 is turned on.

In some embodiments, the control part 40 is configured to control the OLED module 32, the LED module 34 and the light bar 50 to be turned off when the household appliance 100 is in the power saving state. Therefore, the power consumption of the household appliance 100 can be saved, and the invalid working time of the OLED module 32, the LED module 34 and the light bar 50 can be reduced, so that the service lives of the OLED module 32, the LED module 34 and the light bar 50 are prolonged.

Specifically, in the power saving state, when the user wants to wake up the home appliance 100 again, the home appliance 100 may be woken up and enter the standby state by touching any region of the touch screen 36.

In some embodiments, the control portion 40 is used to control the OLED module 32 to be dimmed and the LED module 34 to be turned off and the light bar 50 to be scrolled in the standby state of the household appliance 100. The power consumption of the household appliance 100 in the standby state can be reduced.

Specifically, the household appliance 100 may be considered to enter a standby state when the household appliance 100 does not receive an operation instruction within a certain time or is not in a state of executing the command, and after entering the standby state, the control part 40 may control to reduce the brightness of the display of the OLED module 32, and control to turn off the display of the LED module 34 and control the light bar 50 to scroll and display.

When the user touches any area of the touch screen 36, the OLED module 32 and the LED module 34 normally display the first content and the second content. The light bar 50 normally displays the color of the corresponding cooking mode. The voice module 70 may broadcast voice information of the current cooking mode, such as "grill mode", "microwave mode", and the like.

In some embodiments, when the household appliance 100 is in the parameter setting state, the control portion 40 is configured to set a cooking mode and an adjustable parameter according to the operation instruction, and is configured to control the LED module 34 to flash and display the adjustable parameter after the adjustable parameter corresponding to the cooking mode reaches a maximum value, and is configured to control the light bar 50 to display a light color corresponding to the cooking mode. So, lamp strip 50 can feed back the culinary art mode that domestic appliance 100 is different in real time to when setting up the adjustable parameter that the culinary art mode corresponds, LED module 34 can also twinkle the extreme value of suggestion adjustable parameter, has promoted domestic appliance 100's intellectuality, and convenience of customers uses.

Specifically, after the user switches different cooking modes, the voice module 70 can broadcast corresponding voice information in real time, for example, after the micro-steaming oven is switched from the microwave mode to the barbecue mode, the voice module 70 broadcasts a "barbecue mode" voice, and after the micro-steaming oven is switched to the steam mode, the voice module 70 broadcasts a "steam mode" voice.

In the adjustment of the adjustable parameter, in the case that the adjustable parameter is adjusted to the maximum value or the minimum value, the voice module 70 may broadcast corresponding voice information, such as "maximum temperature", "minimum temperature", "maximum time", "minimum time", and the like. Meanwhile, the OLED module 32 may also display a prompt message, which may include an adjustment range of the adjustable parameter to remind the user to set the adjustable parameter within the range.

In some embodiments, in the operating state of the household appliance 100, the control portion 40 is configured to set a cooking mode and adjustable parameters according to the operation instruction, and is configured to control the OLED module 32 to display the cooking mode, control the LED module 34 to display the adjustable parameters corresponding to the cooking mode, and control the light bar 50 to display the light color corresponding to the cooking mode in a progress bar. Thus, the OLED module 32, the LED module 34 and the light bar 50 can feed back the cooking mode, the value of the adjustable parameter and the remaining cooking time of the household appliance 100 in the operating state, which is convenient for the user to check.

In one example, when the micro-steaming oven is in the warm-up state of the grill mode, the OLED module 32 displays the current cooking mode, the LED module 34 can display the current temperature and the set temperature of the cavity of the micro-steaming oven, and the light bar 50 displays the light color of the current cooking mode and is normally on.
