In addition, the door can realize a projection display and an operation function, has better visibility, is easier to operate, and can observe the operating condition inside the washing machine.

As a further measure, the touch operation device 5 is a touch film or a touch panel, and is installed on the outer surface of the discolorable display area 4. In addition, it corresponds to the displayed operation display menu, and receives the operation signal corresponding to the operation display menu.

The area of the touch film is equal to or smaller than the area of the discolorable display area 4, and covers a part or all of the discolorable display area 4. The touch film may be capable of receiving the operation signal corresponding to the operation display menu corresponding to the displayed operation display menu.

As a further alternative, the door 2 is located on the ceiling or side of the washing machine. Further, the door 2 includes a transparent visible portion and an opaque frame, and a discolorable display area 4 is provided in the transparent visible portion. When projected by the projection device, the transparent visible part becomes dark.

The washing machine of this embodiment may be an open ceiling type washing machine such as a pulsator washing machine, or may be a side open type washing machine such as a drum washing machine. Further, the transparent observation window in the conventional door 2 may be used, or the door 2 having a transparent visible portion may be manufactured as needed. Since the discolorable display area 4 is provided only in the transparent visible portion, the material is saved and the cost is suppressed.

As a further alternative, the projection device and the control device are provided in the opaque frame of the main body 1 and / or the door 2.

Preferably, the washing machine is a pulsator washing machine, the projection device is provided on the panel base of the washing machine, and the control device is provided on the opaque frame. Alternatively, both the projection device and the control device are provided in the opaque frame.

Alternatively, the washing machine is a drum washing machine, and a projection device and a control device are provided on an opaque frame and / or a surface plate.

The projection device may be provided inside the washing machine or outside, and it is sufficient that the projection display can be performed on the discolorable display area 4. In this proposal, the projection device is preferably provided on the panel base of the pulsator washing machine, and the control device is provided on the opaque frame of the door 2, or both of them are provided on the opaque frame. As a result, the projection distance by the projection device can be shortened, the clarity of the projection display is further improved, and a better display screen is formed, so that the user experience is enhanced.

Control method:
The washing machine controls the projection device to project and display the operation display menu on the discolorable display area based on whether or not the door 2 is closed, and controls the discolorable display area to be dark. Next, the washing machine receives the operation signal of the user in the touch operation device 5, and controls the projection device to adjust and project and display the corresponding contents.

When the washing machine determines that the user has not operated for a certain period of time, the washing machine automatically turns off the projection device and changes the discolorable display area to a relatively light color or transparent.

As shown in FIGS. 1 to 5, the present embodiment further limits the first embodiment. An electrochromic structure 3 is provided in the discolorable display area 4 on the door 2 of the washing machine in this embodiment. The discolorable structure is an electrochromic structure 3 electrically connected to a control device, and is provided in a part or the whole area of the door 2. In addition, it is possible to receive the light beam projected by the projection device and display the corresponding projection content.

In a preferred embodiment, the electrochromic structure 3 of the present invention may be a conductive glass or a conductive film, or other feasible device, and in the preferred embodiment, a dark-colored conductive glass. The conductive glass has a dark color in the electric power state and can change to transparent in the energized state.

The projection device is mounted on the body 1 and / or the door 2 so that the projection port faces the electrochromic structure 3 of the door 2. When the projection device projects and displays the display content of the washing machine on the electrochromic structure 3, the clarity of the display content can be greatly improved by setting the electrochromic structure 3 to the electric power cut state, so that the display content can be displayed even from a distance. The contents can be clearly observed. Further, when the user wants to check the state inside the tub, a good transparent window can be provided by energizing the electrochromic structure 3 to change the transparency, so that the user can observe the operating condition inside the washing machine at any time. It is also convenient to do.

As a further measure, the door 2 is entirely formed of conductive glass, and the door 2 is entirely a discolorable display area 4. Further, the touch operation device 5 is provided on the outer surface of the door 2 and corresponds to the operation display menu displayed.

Since the door 2 is entirely made of dark conductive glass, the appearance of the washing machine is beautiful and elegant, and the texture is calm and elegant. Further, since the entire door 2 can be used as a display area, the area is large, the display effect is excellent, and the observation field of view is good. The touch film can cover the door 2. Moreover, the sensing contact of the touch film corresponds to the display content projected on the door 2. When the user throws in clothes and closes the door 2, the user can visually recognize the operation menu displayed on the door 2 and select a program based on the needs.

As a preferred embodiment, the discolorable display area 4 is provided with a projection toggle key for turning on the projection device.

The projection device can be temporarily turned off to save energy during the execution of each program by the washing machine. When the user wants to check the operation display menu of the washing machine, he / she may inspire the projection device to be turned on. In this proposal, a projection toggle key for turning on the projection device may be provided at an arbitrary position of the touch film or the touch panel in the discolorable display area 4 so that this function can be realized. The washing machine automatically turns off the projection device when it determines that the user has not operated for a certain period of time. The user is inspired by the projection toggle key if he wants to manipulate or check the display. Then, the control device receives the operation signal and controls the projection device to perform the projection display again.

The projection toggle key is not limited to the manual toggle key, and an auto-trigger sensor may be installed. This sensor may be an infrared sensor or a distance sensor. When it is detected that the user is within a predetermined distance range, that fact is automatically fed back to the control device, and the control device controls the projection device to perform the projection display. Further, when it is detected that the user has left the predetermined distance range, the fact is automatically fed back to the control device, and the control device controls to turn off the projection device.

As another preferred embodiment, the discolorable display region 4 is further provided with a conductive toggle key for inspiring the conductive glass to be energized.

The control device can automatically control the conductive glass to be energized after the projection device is turned off. As a result, the door 2 becomes transparent, which is convenient for observing the operating condition in the washing tub in the process of executing the program by the washing machine. In addition, if the user wants to check the inside of the washing machine while the projection device is projecting on the discolorable display area, the conductive glass can be immediately energized and transparent by directly contacting the conductive toggle key. It becomes a state.

Control method:
The user throws in clothes and closes the door 2 of the washing machine. The washing machine determines whether or not the door 2 is closed, and if the determination result is YES, the projection device controls the operation display menu to be projected and displayed in the discolorable display area, and the conductive glass is cut off. Control to be in a state. As a result, the discolorable display area becomes darker, so that the display content becomes clearer.

On the other hand, when the washing machine determines that the user has not operated for a certain period of time or receives a conductive trigger signal, the washing machine turns off the projection device and controls the conductive glass to be energized. As a result, the conductive glass becomes transparent, which makes it easier to observe the state inside the cleaning tank.

If the determination result is NO, the projection device is controlled to be turned off, or the projection device is controlled to display the projection at another position. The other locations include at least a panel base and a detergent case.

This example further limits Example 1. There are a plurality of discolorable display areas 4 on the door 2 in this embodiment, and a touch operation device 5 is provided on the surface of each discolorable display area 4. When the control device determines that the projection device has projected onto an arbitrary discolorable display area 4, the control device is put into an operating state by energizing the touch operation device 5 at the corresponding position. This makes it possible to receive and respond to the user's touch operation.

When the projection device projects onto the discolorable display area 4 at an arbitrary position, the control device improves the intelligibility of the display by controlling the conductive film or the conductive glass at this position to be cut off. In addition, the conductive glass or conductive film at other positions is controlled to be energized and made transparent so that the situation inside the tank can be observed.

This example further limits Example 1. The discolorable display area 4 on the door 2 in this embodiment is provided with a discolorable structure. The discolorable structure is a photochromic layer. The photochromic layer covers the discolorable display area 4. When the projection device projects onto the discolorable display area 4, the color of the photochromic layer becomes dark, but when the projection device does not project, the photochromic layer changes to light color or transparent.

The photochromic layer is formed of a photochromic material and becomes a relatively light color or transparent in the absence of light or in the absence of light, but becomes a relatively dark color when irradiated with strong light. The photochromic layer is applied so as to adhere to the transparent area of the door 2 to form the discolorable display area 4. When the projection device is turned on and projected onto the door 2, the color of the photosensitive material becomes darker due to the strong light emitted from the projection device, so that the clarity of the display can be improved. On the other hand, when the projection device is turned off and the strong light disappears, the discolorable display area gradually returns to a relatively light color or transparency, which makes it easier to observe the internal situation.

As a preferred embodiment, the door 2 of the washing machine is provided with an enhanced light source. The enhanced light source irradiates the photochromic layer to enhance the discoloration effect of the photochromic layer.

The enhanced light source may be provided on the door 2 or on the internal panel base, and irradiates the photochromic layer. Reinforced light sources are turned on and off so that the photochromic layer becomes a darker color when projection is on to enhance display clarity, and the photochromic layer becomes a relatively light or transparent color when not projected. Match with the projection device.

The control method includes the following steps.

The washing machine determines whether or not the door 2 is closed, and if the determination result is YES, the projection device controls the operation display menu to be projected and displayed in the discolorable display area, and the enhanced light source is turned on. Control. As a result, the discolorable display area becomes darker, so that the intelligibility of the display is enhanced.

On the other hand, when the washing machine determines that the user has not operated for a certain period of time, the washing machine controls to turn off the projection device and turn off the enhanced light source. As a result, the discolorable display area becomes transparent, which makes it easier to observe the state inside the washing tank.

If the determination result is NO, the projection device is controlled to be turned off, or the projection device is controlled to display the projection at another position. The other locations include at least a panel base and a detergent case.
