[Embodiment 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 the drum-type washing machine 10 (hereinafter, simply referred to as the washing machine 10) of the first embodiment. The washing machine 10 has an inlet 201 for laundry in front of the housing 200, and a door 100 is provided so as to cover the inlet 201. That is, the door 100 is provided to open and close the front of the housing 200.

Although most of the general drum-type washing machines, the shape of the door is a circular shape matching the inlet of the washing tank, but the door 100 in the washing machine 10 of the first embodiment is almost as if covering the entire front of the housing 200 Rectangular shape. Thus, the door 100 has an area spanning the input port 201 and the portion other than the input port 201, and is formed in a larger area than the conventional round door. Further, the door 100 as a whole is a half mirror, and the inside of the washing machine 202 (inside of the input port 201) can be seen through the door 100.

In the washing machine 10, the door 100 displays an interface screen IF (see FIGS. 2 and 3) for providing information to the user and accepting the user's operation. In the washing machine 10, as shown in FIG. 2(a), the entire surface (or most of it) 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 interface screen IF is displayed using the entire (or most of) the screen display area DP, it is easy to perform a large-area operation display, and the degree of freedom of expression is increased compared to the operation display portion of the conventional washing machine. In addition, the display area of the interface screen IF is not limited to the area overlapping the input port 201, and the interface screen IF can be displayed in the area spanning the inside and outside of the input port 201 when viewed from the front. As a result, it is easy to display the interface screen IF at a position that is most easy for the user to see. Furthermore, since the restriction on the arrangement of the operation display unit on the upper part of the washing machine 10 is removed, the washing tub 202 can be arranged near the uppermost part of the housing 200. Thereby, the washing tank 202 can be arranged at a high position, and the laundry can be easily taken in and taken out.

In addition to the interface screen IF that increases the degree of freedom of expression in a large area, the user can display an information screen for providing various information to the user in addition to the operation screen for operating the washing machine 10. For example, when the washing machine 10 is connected to the Internet via IoT (Internet of Things), the following information may be displayed. Thus, for the user, the washing machine 10 can become a management related to washing. In addition, some of the information screens of the following examples may be a demonstration screen in 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. ・Guide to purchase consumables: A sensor installed in the detergent box detects the amount of used detergent, grasps the cumulative amount of detergent used, and displays the purchase guide screen when the detergent 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: You can read the information of clothes (washings) put into the washing machine 10 from an electronic tag (described later in Embodiment 2), etc., and analyze the user's preferred clothes from this information. Display information about clothes that users might like. ・Information on the local laundry: display the promotional information of the laundry in the area where the user lives, the time to open and close the store, etc.

In addition, 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 setting. Alternatively, the display position and display area of the interface screen IF may be switched according to the content of the information displayed on the interface screen IF. Furthermore, the display layout in the interface screen IF may be changed according to user settings.

As a specific example, as shown in (b) and (c) of FIG. 2, the display area of the interface screen IF can be changed. Fig. 2(b) is a standard size interface screen IF, and Fig. 2(c) is an enlarged size interface screen IF. The enlarged-size interface screen IF can increase the size of the displayed text and image even when displaying the same information as the standard-size 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 easy to see the characters and images, and the operability is improved. On the other hand, for users who can see clearly without enlarging text or images, the compact standard-size interface screen IF is easy to see and also improves operability. The user can arbitrarily set the interface screen IF to a standard size or an enlarged size.

In addition, as another specific example, as shown in (a) to (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 as high as possible, which is easy for the user to see and the operability is also improved. Therefore, in this case, as shown in FIG. 3( a ), the display position of the interface screen IF may be set to a high position. On the other hand, when the washing machine 10 itself is placed at a high position such as on a pedestal, as shown in FIGS. 3(b) and (c), the display position of the interface screen IF can be set to a lower position , Set to a position that is easy for the user to see. Of course, basically, the user can 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, the display method is assumed to use a projector or a transflective liquid crystal panel.

4( a) and (b) are schematic cross-sectional views showing a configuration example when the interface method IF is displayed using the projector 300 in the display method. In recent years, ultra-single-focus projectors that can project large screens even at short distances have been put into practical use. For the projector 300 used in the washing machine 10, the use of such ultra-single-focus projectors is suitable.

In the door 100, the half mirror glass 101 is mounted 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 use this space SP to project an image (interface screen IF) on the half mirror glass 101.

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

In addition, when the display method uses a transflective liquid crystal panel, the configuration may be such that the transflective liquid crystal panel is 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. In the washing machine 10, the reflective area of each pixel can be used to display the interface screen IF. On the other hand, in the transmission area, the interior of the washing tub 202 can be seen through the door 100, and the function of the half mirror can be exerted.

The detection of the user's operation on the interface screen IF can be easily detected, for example, by providing a touch panel (operation detection unit) at the front of the door 100. 40 However, the detection method by the user is not particularly limited in the present invention, and other known methods can also be used. For example, an infrared camera (operation detection unit) is used to detect the movement of the user's hand before the interface screen IF, and by analyzing the movement, the operation by the user can be detected.

[Embodiment 2] The interface screen IF described in the first embodiment can have a larger area than the operation display unit in the conventional washing machine, and it is possible to display various information using the operation by the user. In the second to sixth embodiments, specific examples of the display method and operation method of the interface screen IF will be described.

FIG. 5 is an interface screen IF that makes it possible to perform the most appropriate setting according to the laundry when performing washing. For example, it is assumed that the reader of the electronic tag is provided in 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 To display using the information read. In the example of FIG. 5, there is displayed information identifying the clothes with an electronic tag (for example, “Mom’s dress”), and washing and drying conditions suitable for the clothes. In addition, for the reader of the electronic tag, the washing machine 100 detects the user's opening of the washing machine 100 through the door opening and closing sensor, and the power can be connected in such a manner as to start reading simultaneously with the opening of the washing machine 100.

In addition to the display shown in FIG. 5, when delicate clothes requiring special washing are put into the washing tub 202, etc., it is assumed that the following display is performed on the interface screen IF. ・In the case where the washing program selected by the user is not preferable for the clothes thrown into the washing tank 202, a display that draws attention (prompts the user to change the washing conditions, etc.) is performed. ・From the information of the electronic tag, we notify the appropriate lotion for the clothes put in. -Register favorite clothes information in the memory of the washing machine 10, memorize special menu settings when washing favorite clothes, or manage the number of washing of favorite clothes. ・Suggestions for changing clothes according to the season. ・From the clothes put into the washing tank and the clothes taken out from the washing tank, the forgotten removal from the washing tank 202 is detected, and the notice of the forgotten clothes is detected. If you forget to display the clothes, you can display the characteristics and pictures of the clothes on the screen.

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

[Embodiment 3] FIG. 6 is an interface screen IF in the case of performing error display and maintenance indication in the washing machine 10. For example, when an error occurs in the washing machine 10 or a situation requiring repair occurs, the erroneous part or repaired part can be displayed in the corresponding part of 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 can be displayed on the lower left portion where the lint filter is arranged. Similarly, if errors and maintenance information about the drying filter are in the upper right part, and errors and maintenance information about the detergent box and water supply valve are in the upper left part, if the corresponding parts are displayed, the user can It is easy to identify the location where the error occurred and the location to be repaired, and this response can be performed quickly.

In this way, the interface screen IF of the third embodiment uses the entire front of the door 100 disposed in front of the washing machine 10 to display an error of the washing machine 10 or information corresponding to maintenance. The error or maintenance information includes the position information of the target part in front view by being displayed in which part of the door 100 in front view. 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.

[Embodiment 4] In the conventional washing machine, the operation method of pressing (touching) small buttons with fingertips is the mainstream, and the user is required to perform subtle movements. Therefore, the conventional operation method puts pressure on the user.

On the other hand, the interface screen IF in the washing machine 10 is not only displayed on the large screen, but the entire interface screen IF (the entire front of the door 100) can be used for operation input, and can be operated by the palm or the arm. 7 is a diagram showing an example of an operation method of the washing machine 10 by a user who uses the interface screen IF.

The interface screen IF shown in FIG. 7 is regarded as an operation part by viewing the outer peripheral part of the washing tank 202 and the inner peripheral part of the washing tank 202 which can be seen through the half mirror glass 101 of the door 100, such as tracking the washing tank 202 It detects the user's movements (any one of fingers, palms, arms, etc.), and accepts the user's operation. At this time, an image such as the flow of water may be displayed on the interface screen IF in accordance with the sliding motion of the hand. Such an operation is, for example, a condition selection operation to follow the direction of the user, or an instruction operation to start the rotation of the washing tub 202. Of course, there may be operations assigned to actions other than these. For example, the action of the user touching the inner peripheral portion of the washing tub 202 can be assigned to the selection condition determination operation, washing stop instruction operation, and the like.

In addition, the speed of the user's movement can be reflected in the operation content. For example, in the case where the washing is to be strengthened, the outer peripheral portion may be tracked in a faster rotation in the above-mentioned operation of tracking the outer peripheral portion of the washing tub 202.

In this way, the interface screen IF of the fourth embodiment is different from the conventional operation method of pressing (touching) a small button with a fingertip, and the washing machine 10 can be operated with a larger motion by a finger, palm, arm, or the like. Thus, the user can operate the washing machine 10 without pressure.

In addition, 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 movement of the user's hand and detects the content of the operation instruction.

[Embodiment 5] 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 unit disposed on the upper part of the casing or recognize the inside of the washing tub through the window of the door. However, since any confirmation method is difficult to confirm from a distance, the user must approach the washing machine to confirm, which causes trouble to the user. Moreover, such a confirmation method is not friendly to users. FIG. 8 is a diagram showing an interface screen IF for easily showing the state of the operating washing machine 10 to the user. The screen shown in FIG. 8 is such that the operation status of the washing machine 10 can be easily understood by the user, and the steps of washing are displayed in an animation or the like.

For example, the interface screen IF of FIG. 8 is an animation screen showing that the current operating state of the washing machine 10 is a person running in a rotating vehicle during the washing process. In this animation screen, the appearance of a person running is regarded as the rotation of the washing tub 202, and the user can recognize from the screen that the current operating state of the washing machine 10 is in the washing process. In addition to this, for example, in the drying process, it is set as an animation screen where the clothes are dancing, and in the rinsing process, it is set as an animation screen showing the flow of waterfall-like light, and various expressions can be imagined method. Such an animation screen is easy to see even if the user leaves the washing machine 10 to some extent, and the information content displayed on the interface screen IF can be made entertaining.

In addition, the interface screen IF that shows the steps of such washing in a dramatic manner may be always displayed during the operation of the washing machine 10, or may be displayed at an arbitrary timing. For example, it may be displayed when the user thinks about seeing the interface screen IF according to a predetermined operation operation performed, 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 animated 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 display with entertainment.

[Embodiment 6] When the washing machine 10 is provided with illumination in the washing tank 202, when the illumination in the washing tank 202 is on, it is not necessary to display the area overlapping the washing tank 202 on the interface screen IF. That is, in the washing machine 10, since the door 100 displaying the interface screen IF uses a half mirror, the lighting in the washing tub 202 lights up to make the display of the interface screen IF unclear.

As a control example of the sixth embodiment, the following examples may be mentioned. ・When the lighting in the washing tank 202 lights up (when a certain illuminance is higher), the display of the interface screen IF is temporarily interrupted. That is, the lighting in the washing tank 202 is temporarily turned on when the user directly recognizes the inside of the washing tank 202, etc., and even when the lighting is turned on, it turns off after a predetermined time has passed. 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 tank 202 is turned on (when a certain illuminance or more), the display area of the interface screen IF is changed so that the area overlapping the washing tank 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 FIG. 3(b)) in which the interface screen IF includes an area overlapping with the washing tub 202 is illuminated, the change is made to the interface screen IF not including laundry. The display state of the area where the grooves 202 overlap (for example, the display state shown in (a) of FIG. 3 ). Such a change control of the display area may be a temporary one when the lighting is turned on, or may be a display that is restored after being turned off.

In this way, with the exclusive control of the lighting and lighting in the washing tank 202 of the sixth embodiment, the interface screen IF can prevent the unclear interface screen IF from being displayed during the lighting. However, it is not necessary to implement the above-mentioned exclusive control in the washing machine 10, and as the display performance, the temporary lighting and the interface screen IF may be simultaneously displayed.

[Embodiment 7] In the first embodiment, when a projector is used as the display method of the interface screen IF, a configuration in which the projector is arranged inside the washing machine 10 is exemplified and illustrated. With this configuration, the appearance of the washing machine 10 can be made compact. However, the present invention is not limited to this, and a configuration in which the projector is arranged outside the washing machine 10 can also be assumed.

9( a) and (b) are configurations in which the external projector 301 is combined with the washing machine 10. For example, the external projector 301 is attached to a wall or the like around the washing machine 10, and can project the interface screen IF from the outside with respect to the door 100 (see (a) of FIG. 9 ). In addition, the external projector 301, the detection unit (infrared camera) that detects the user's operation with respect to 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 have a well-known configuration, detailed description will be omitted here.

In addition, 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 may be the side surface of the washing machine 10, the wall surface of the room, or the like (see (b) of FIG. 9 ). In the case where the interface screen IF is displayed on the door 100, when the door 100 is opened and laundry is put in, etc., there is a restriction on the sense of operation that cannot be operated through the interface screen IF. In contrast, in the configuration using the external projector 301, the user can freely select the projection portion of the interface screen IF on the side wall of the washing machine 10, the wall surface of the installation room, and the like. Therefore, the interface screen IF can be arranged at a height suitable for the user without disturbing the preparation for washing, and the user's inconvenience during the operation can be eliminated.

Although the external projector 301 can be fixed to the body of the washing machine 10 with a free arm like a swing arm, as shown in FIG. 9, by configuring the external projector 301 and the washing machine 10 as separate bodies, the degree of freedom of installation is improved . In addition, when the external projector 301 and the washing machine 10 are provided separately, it is preferable that the external projector 301 wirelessly connect the washing machine 10 by short-distance wireless communication means. Furthermore, the external projector 301 may be configured to be mounted on the main body of the washing machine 10, or may be configured to be capable of wireless charging during installation.

In addition, as a modification of the case where the interface screen IF is displayed in addition to the door 100 of the washing machine 10, as shown in FIG. 10, it is assumed that the mirror of the hand washing station adjacent to the washing machine 10 also serves as the operation display unit. Such a mirror can be realized by the transflective liquid crystal panel 400, for example. That is, the semi-transmissive liquid crystal panel 400 is generally used as a mirror with the mirror surface of the reflective area, and can display the interface screen IF through the transmissive area as required. Of course, the semi-transmissive liquid crystal panel 400 is preferably wirelessly connected to the washing machine 10 by a short-range wireless communication method.

All aspects of the embodiment disclosed this time are examples and are not to be used as a basis for a limited interpretation. Therefore, the technical scope of the present invention is not explained only by the above-mentioned embodiment, but is defined based on the description of the patent application scope. In addition, it includes the meaning equivalent to the patent application scope and all changes within the scope.
