[Implementation Mode 1]

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing the appearance of a front-loading-type washing machine 10 (hereinafter, simply referred to as washing machine 10 ) according to Embodiment 1. As shown in FIG. Washing machine 10 has laundry inlet 201 on the front surface of casing 200 , and door 100 is provided so as to cover inlet 201 . That is, the door 100 is provided to open and close the front surface of the casing 200 .

Although most of the general front-loading washing machines have a door shape that is circular to match the inlet of the washing tank, the door 100 in the washing machine 10 according to Embodiment 1 is formed to cover the front of the casing 200 as a substantially whole. rectangular shape. Thus, the door 100 has an area spanning the inlet 201 and a portion other than the inlet 201 , and is formed to have a larger area than a conventional round door. Moreover, the door 100 is almost entirely a half mirror, and the inside of the washing machine 202 (the inside of the inlet 201 ) can be seen through the door 100 .

In the washing machine 10, an interface screen IF (see FIGS. 2 and 3 ) for providing information to the user and accepting operations by the user is displayed on the door 100 . In the washing machine 10, as shown in FIG. 2( a ), the entire surface (or most) of the door 100 can be used as the screen display area DP. Furthermore, the interface screen IF can be displayed on the whole or a part of the screen display area DP.

In the washing machine 10, if the whole (or most) of the screen display area DP is used to display the interface screen IF, it is easy to perform a large-area operation display, and the degree of freedom of expression is increased compared with the operation display part of the conventional washing machine. Moreover, the display area of the interface screen IF is not limited to the area overlapping with the input port 201, and can be displayed in an area straddling the inside and outside of the input port 201 when viewed from the front. Interface screen IF. Thereby, it becomes easy to display the interface screen IF at the position which is most easy to see for a user. Furthermore, since the constraint of disposing the operation display unit on the upper part of the washing machine 10 is removed, the washing tank 202 can be disposed near the uppermost part of the casing 200 . Thereby, washing tank 202 can be arrange|positioned at a high position, and it becomes easy to take out and put in the laundry.

In addition to the operation screen for the user to operate the washing machine 10, the interface screen IF having a larger area to increase the freedom of expression can also display an information screen for providing various information to the user. For example, when the washing machine 10 is connected to a network through IoT (Internet of Things), the following information display can also be performed. Thus, for the user, washing machine 10 can be used for management related to washing. In addition, some of the information screens in the following examples may be demonstration screens on the washing machine 10 in standby.

‧Display of weather forecast: For example, a human body sensor is installed in the washing machine 10, and when the user approaches, the weather forecast information obtained from the Internet is displayed.

‧Purchasing guidance for consumables: The sensor installed in the detergent box detects the amount of used lotion, grasps the cumulative usage of lotion, and displays a purchase guide screen during the period when the lotion is decreasing. At this time, it is also possible to purchase from the Internet through the interface screen IF of the washing machine 10 .

‧Recommendation of clothes that the user may like: The information of the clothes (laundry) put into the washing machine 10 can be read from electronic tags (described later in Embodiment 2), and the clothes that the user prefers can be analyzed from the information. Shows information about clothes the user might like.

‧Regional laundromat information: display promotional information, opening and closing times, etc. of laundromats in the user's living area.

Also, one of the features of the washing machine 10 is that the user can arbitrarily change the display area of the interface screen IF. Specifically, the display area and display position of the interface screen IF can be arbitrarily changed according to the user's settings. Or, it can also be based on the information displayed on the interface screen IF content, and switch the display position and display area of the interface screen IF. Furthermore, the display layout (layout) in the interface screen IF may be changed according to the setting of the user.

As a specific example, as shown in (b) and (c) of FIG. 2, the display area of the interface screen IF can be changed. (b) of FIG. 2 is a standard-sized interface screen IF, and FIG. 2(c) is an enlarged-sized interface screen IF. The enlarged-sized interface screen IF can increase the size of displayed characters and images even when displaying the same information as the standard-sized interface screen IF. Therefore, for users who have difficulty seeing small characters and images, by setting the interface screen IF to an enlarged size, it is easier to see the characters and images, thereby improving operability. On the other hand, for users who can clearly see characters and images without enlarging them, the compact standard-sized interface screen IF is easy to see and improves operability. The user can arbitrarily set the interface screen IF to a standard size or an enlarged size.

Moreover, as another specific example, as shown in (a)-(c) of FIG. 3, the display position of the interface screen IF can be changed. For example, when the washing machine 10 is placed on the floor, it is assumed that the interface screen IF is displayed at a position as high as possible, so that it is easy for the user to see and the operability is improved. Therefore, in this case, as shown in (a) of FIG. 3 , it is only necessary to set the display position of the interface screen IF at a high position. On the other hand, when the washing machine 10 itself is placed at a high position such as a pedestal, as shown in (b) and (c) of FIG. 3 , the display position of the interface screen IF can be set at a lower position. , set it at a position that is easy for the user to see. Of course, basically, the user can also arbitrarily set the display position of the interface screen IF.

In the washing machine 10, as a configuration for changing the display area and display position of the interface screen IF, a display method using a projector or a transflective liquid crystal panel is assumed.

(a) and (b) of FIG. 4 are schematic cross-sectional views showing configuration examples in a case where the projector 300 is used to display the interface screen IF in the display method. In recent years, even at short distances A super-single-focus projector for large-screen projection is put into practical use, and the projector 300 used in the washing machine 10 is suitable for use of such a super-single-focus projector.

In the door 100, a half mirror glass 101 is installed on the front side of the frame (outer frame). Therefore, when the door 100 is closed, a space SP is generated between the half mirror glass 101 and the housing 200 . The projector 300 can project an image (interface screen IF) on the half mirror glass 101 using this space SP.

The placement position of the projector 300 is not particularly limited as long as it is a position where an image can be projected on the half mirror glass 101 . For example, in FIG. 4( a ), the projector 300 is disposed on the upper front side of the casing 200 . In addition, in FIG. 4( b ), the projector 300 is arranged at the central part of the back side of the door 100 .

Also, when a transflective liquid crystal panel is used as a display method, the transflective liquid crystal panel may be arranged at the position of the half mirror glass 101 shown in FIG. 4 . In the transflective liquid crystal panel, each pixel has a reflective area and a transmissive area, and in the washing machine 10 , the interface screen IF can be displayed using the reflective area of each pixel. On the other hand, in the transmissive area, the inside of the washing tank 202 can be seen through the door 100, and the function of a half mirror can be exhibited.

The detection of the user's operation on the interface screen IF can be easily detected by, for example, providing a touch panel (operation detection unit) at the front of the door 100 . However, the detection method of the user's operation is not particularly limited in the present invention, and other known methods can also be used. For example, by detecting the movement of the user's hand in front of the interface screen IF using an infrared camera (operation detection unit), and analyzing the movement, it is possible to detect the operation by the user.

[Implementation Mode 2]

The interface screen IF described in Embodiment 1 can be made larger than the operation display area of the conventional washing machine, and various information displays utilizing this can be made by the user's operation. as possible. In Embodiments 2 to 6, specific examples of the display method and the operation method of the interface screen IF will be described.

FIG. 5 is an interface screen IF for enabling optimum setting according to laundry when washing. For example, it is assumed that the reader of the electronic tag is arranged on the front of the washing machine 10 or near the opening of the washing tank 202, and when the clothes with the electronic tag are put into the washing tank 202, the information of the clothes is read from the electronic tag. , and display using the read information. In the example of FIG. 5 , the information of the clothes with electronic tags (for example, "mother's dress") is displayed, and the washing and drying conditions suitable for the clothes are displayed. In addition, as for the reader of the electronic tag, the washing machine 100 detects that the user opens the washing machine 100 through the door opening and closing sensor, and it only needs to be connected to the power supply so as to start reading at the same time as the washing machine 100 is opened.

In addition to the display described in FIG. 5 , it is assumed that the following display is performed on the interface screen IF when delicate clothes requiring special washing are put into the washing tub 202 .

- When the washing course selected by the user is not suitable for the clothes thrown into the washing tub 202, display to call attention (prompt the user to change the washing conditions, etc.).

‧From the information of the electronic tag, it notifies the appropriate detergent for the put-in clothes.

‧Register the favorite clothes information into the memory of the washing machine 10, memorize the special menu setting when washing the favorite clothes, or manage the washing times of the favorite clothes.

‧Suggestions for changing clothes according to the season.

‧From the comparison of the clothes put into the washing tank and the clothes taken out from the washing tank, it is detected that the laundry tank 202 is forgotten to be taken out, and the clothes that are forgotten to be taken out are notified. If you forget to take out the display of the clothes, you can display the characteristics and pictures of the clothes on the screen and notify.

In this way, the interface screen IF of the second embodiment can be displayed in various ways by using the information read from the electronic tag when washing the clothes with the electronic tag. If there is an interface screen IF having a large area, such various display screens can be easily provided.

[Implementation Mode 3]

FIG. 6 is an interface screen IF in a case where an error display and a maintenance display in the washing machine 10 are performed. For example, if an error occurs in the washing machine 10 or a repair is required, the location of the error or the location to be repaired can be displayed on the corresponding location in the washing machine 10 viewed from the front.

For example, in the interface screen IF when the lint filter is clogged, as shown in FIG. 6 , an error display can be displayed on the lower left portion where the lint filter is arranged. Similarly, if the errors and maintenance information related to the dry filter are displayed on the upper right part, and the errors and maintenance information related to the detergent box and the water supply valve are displayed on the upper left part, if they are displayed at the positions corresponding to each component, the user can It is easy to identify the error occurrence part and the part that requires maintenance, and it is possible to quickly perform the countermeasures.

In this way, the interface screen IF of the third embodiment uses the entire front of the door 100 disposed on the front of the washing machine 10 to display errors of the washing machine 10 or information corresponding to maintenance. In the error or maintenance information, depending on which part of the door 100 is displayed in the front view, the position information in the front view of the target part is included. Thus, the interface screen IF of the third embodiment can intuitively indicate to the user which part of the washing machine 10 should be confirmed.

[Implementation Mode 4]

In the conventional washing machine, the operation method of pressing (touching) a small button with a fingertip is the mainstream, and the user is required to perform fine movements. Therefore, the conventional operation method puts pressure on the user.

In contrast, the interface screen IF in the washing machine 10 is not only displayed on a large screen, but the whole of the interface screen IF (the whole in front of the door 100) can be used for operation input, which can be realized by Palm and arm operation. FIG. 7 is a diagram showing an example of an operation method of the washing machine 10 by the user using the interface screen IF.

The interface screen IF shown in FIG. 7 is to regard the outer periphery of the washing tank 202 visible through the half-mirror glass 101 of the door 100 and the inner circumference of the washing tank 202 as the operation part, such as tracking the washing tank 202 An example of detecting the user's motion (any one of fingers, palms, arms, etc.) and accepting the user's operation is generally performed on the peripheral portion of the device. At this time, an image like water flow may also be displayed on the interface screen IF in conjunction with the sliding movement of the hand. Such an operation is assumed, for example, as a condition selection operation to follow the user's direction and an instruction operation to start the rotation of the washing tank 202 . Of course, there may be operations assigned to actions of users other than these. For example, an operation of the user touching the inner peripheral portion of the washing tub 202 can be assigned to an operation of determining a selection condition, an operation of instructing to stop washing, and the like.

In addition, the speed of the user's movement can be reflected in the content of the operation. For example, in the above-mentioned operation of tracking the outer peripheral part of the washing tub 202, the outer peripheral part may be tracked so as to rotate faster when the washing is intended to be stronger.

In this way, the interface screen IF of Embodiment 4 is different from the conventional operation method of pressing (touching) small buttons with fingertips, and the washing machine 10 can be operated with larger movements by fingers, palms, arms, and the like. Thus, the user can operate the washing machine 10 without stress.

Furthermore, in the fourth embodiment, any one of the touch panel and the infrared camera exemplified in the first embodiment may be used as the operation detection unit that detects the content of the operation instruction by detecting the movement of the user's hand.

[implementation mode five]

In the conventional washing machine, in order to confirm the current operation status, the user needs to confirm the display screen of the operation display part arranged on the upper part of the casing, or look inside the washing tank through the window of the door. However, since it is difficult to confirm from a distance regardless of the confirmation method, the user must approach the washing machine to confirm, which causes trouble for the user. Moreover, such a confirmation method is not friendly to the user.

FIG. 8 is a diagram showing an interface screen IF for easily understanding the state of the washing machine 10 in operation to the user. The screen shown in FIG. 8 is a dramatic display of each washing process by animation or the like so that the user can easily understand the operation status of the washing machine 10 .

For example, the interface screen IF in FIG. 8 is an animation screen showing that the current operating status of the washing machine 10 is in the washing process, and that the person is running in the carousel. In this animation screen, the appearance of a person running is regarded as the rotation of the washing tank 202, and the user can recognize the current operating status of the washing machine 10 as being in the washing process from this screen. Also, in addition to this, for example, if in the drying process, it is set as an animated picture showing clothes dancing, and in the washing process, it is set as an animated picture showing the flow of light like a waterfall, and various expressions can be conceived. method. Such an animation screen is easy to see even if the user leaves the washing machine 10 to some extent, and can make the information displayed on the interface screen IF entertaining.

In addition, the interface screen IF that dramatically displays each step of such washing may be always displayed during the operation of the washing machine 10, or may be displayed at an arbitrary timing. For example, the interface screen IF may be displayed when the user expects to see the interface screen IF, or may be displayed when the user approaches the washing machine 10 .

In this way, the interface screen IF of the fifth embodiment can display an animation screen or the like that dramatizes the state of the washing machine 10 in operation, which is easy for the user to understand and can be displayed with entertainment.

[Implementation Mode Six]

When washing machine 10 is equipped with lighting in washing tub 202 , it is only necessary not to display an area overlapping washing tub 202 on interface screen IF while the lighting in washing tub 202 is on. That is, in the washing machine 10, since the door 100 for displaying the interface screen IF uses a half mirror, the lighting in the washing tank 202 is turned on so that the display of the interface screen IF is not clear.

As control examples of the sixth embodiment, the following examples can be mentioned.

‧When the lighting in the washing tank 202 is turned on (when the illuminance is higher than a certain level), the display of the interface screen IF is temporarily suspended. That is, the lighting in the washing tub 202 is temporarily turned on when the user directly recognizes the inside of the washing tub 202, and is turned off after a predetermined time even when the lighting is turned on. Therefore, when the lighting is turned on during the display of the interface screen IF, the display of the interface screen IF may be temporarily interrupted according to the lighting, and the display of the interface screen IF may be redisplayed after the lighting is turned off.

- When the lighting in the washing tub 202 is turned on (at a certain illuminance or higher), the display area of the interface screen IF is changed so that the area overlapping with the washing tub 202 is not displayed on the interface screen IF. For example, it is assumed that when the display state (for example, the display state shown in (b) of FIG. The display state of the region where the grooves 202 overlap (for example, the display state shown in (a) of FIG. 3 ). Such change control of the display area may be temporary when the lighting is turned on, or may be restored to the original display after it is turned off.

In this way, the interface screen IF of the sixth embodiment can prevent the unclear interface screen IF from being displayed when the lighting is turned on by exclusive control of the lighting in the washing tub 202 . However, the above-mentioned exclusive control does not necessarily have to be performed in the washing machine 10, and temporary lighting and display of the interface screen IF may be performed simultaneously as a display effect.

[Implementation Mode 7]

In the first embodiment, when a projector is used as a display method of the interface screen IF, a configuration in which the projector is arranged inside the washing machine 10 is exemplified and described. With this configuration, the appearance of washing machine 10 can be made compact. However, the present invention is not limited thereto, and a configuration in which the projector is arranged outside the washing machine 10 is also conceivable.

(a) and (b) of FIG. 9 are configurations in which an external projector 301 is combined with the washing machine 10 . For example, the external projector 301 is installed on a wall or the like around the washing machine 10, and can project and display the interface screen IF from the outside with respect to the door 100 (see FIG. 9( a )). In addition, the external projector 301, the detection unit (infrared camera) for detecting the user’s operation on the projected interface screen IF, and the adjustment unit for adjusting the size/shape/position of the interface screen IF projected on the door 100 are integration. Since such a detection unit and an adjustment unit are well-known configurations, detailed description thereof will be omitted here.

Also, when such an external projector 301 is used, the projection position of the interface screen IF is not limited to the door 100 of the washing machine 10 . For example, the projection position by the external projector 301 can also be set to a side surface of the washing machine 10, a wall surface of a room, or the like (see (b) of FIG. 9 ). When displaying the interface screen IF on the door 100, when the door 100 is opened to load laundry, etc., there arises restrictions on the sense of operation such as the inability to operate through the interface screen IF. On the other hand, in the configuration using the external projector 301 , the user can freely select where the interface screen IF is projected on the side wall of the washing machine 10 , the wall surface of the installation room, or the like. Therefore, the interface screen IF can be arranged at a position that does not disturb washing preparation and at a height suitable for the user, and the inconvenience of the user during operation can be eliminated.

Although the external projector 301 can be fixed to the main body of the washing machine 10 with a free arm like a swing arm, as shown in FIG. . In addition, when the external projector 301 and the washing machine 10 are separately installed, it is preferable that the external projector 301 communicates wirelessly with the washing machine 10 by means of short-distance wireless communication. connect. Furthermore, the external projector 301 may be configured to be attached to the main body of the washing machine 10, or may be configured to be capable of wireless charging while being attached.

Also, as a modified example of displaying the interface screen IF in addition to the door 100 of the washing machine 10, as shown in FIG. Such a mirror can be realized by, for example, the transflective liquid crystal panel 400 . That is, the transflective liquid crystal panel 400 is usually used as a mirror by using the mirror surface of the reflective region, and can display the interface image IF by using the transmissive region as required. Of course, the transflective liquid crystal panel 400 is preferably wirelessly connected to the washing machine 10 by a short-distance wireless communication method.

All aspects of the embodiments disclosed this time are examples, and should not be taken as a basis for a limited interpretation. Therefore, the technical scope of the present invention is not interpreted only by the above-mentioned embodiments, but is defined based on the description of the claims. In addition, the meanings equivalent to the claims and all changes within the scope are included.
