Example Embodiment

[0048] Example one

[0049] Such as Figure 1-3 As shown, a projection device applied to household appliances includes

[0050] The light source 101 is used to emit a light beam;

[0051] The image display mechanism 102 is used to generate an image of the projected content,

[0052] The light source 101 illuminates the image display mechanism 102 and projects the projection content to form a projection display area 103,

[0053] The relative positions of the light source 101 and the image display mechanism 102 are variable, and the projection content can be switched between the projection display areas 103 by changing the relative positions of the light source 101 and the image display mechanism 102.

[0054] The relative positions of the light source 101 and the image display mechanism 102 are variable. The light source 101 illuminates the image display mechanism 102 and projects the projected content to form a projection display area 103 at different positions. The light source 101 an...

Example Embodiment

[0069] Example two

[0070] The difference between this embodiment and the first embodiment is that there are multiple light sources 101 in this embodiment, which are respectively arranged in different positions of the image display mechanism 102 and electrically connected to the control device 300. The control device 300 according to the user's operation, The light sources 101 in different directions are controlled to be turned on, so that the relative positions of the turned-on light sources 101 and the image display mechanism 102 are changed.

[0071] Such as Figure 5 As shown, multiple light sources 101 are arranged in a row. When the control device 300 controls the leftmost light source 101 in the figure to turn on, a projection display area 103 will be formed on the right side. When the control device 300 controls the rightmost light source 101 to turn on, A projection display area 103 will be formed on the left side, and therefore the projection display area can be switched...

Example Embodiment

[0074] Example three

[0075] Such as Figure 4 As shown, this embodiment is a washing machine having the projection device of Embodiment 1 or Embodiment 2, including a light source 101 for emitting light beams;

[0076] The image display mechanism 102 is used to generate an image of the projected content,

[0077] The light source 101 illuminates the image display mechanism 102 and projects the projection content to form a projection display area 103,

[0078] The relative positions of the light source 101 and the image display mechanism 102 for emitting light beams are variable. A plurality of projection display areas 103 are formed in different parts of the washing machine. By adjusting the relative positions of the light source 101 and the image display mechanism 102, the projection content is displayed In different parts of the washing machine.

[0079] The above-mentioned projection device is installed on the washing machine, and the projection content can be projected into diffe...

Abstract

The invention belongs to the field of the washing machine and specifically relates to a projection device applied to household electrical appliances, a washing machine and a control method. The projection device includes a light source used for emitting light beams; an image display mechanism used for generating the image of projection content, wherein the light source emits light beams to the image display mechanism and the projection content is projected to form projection display areas, the relative position between the light source and the image display mechanism can be changed, the switching of the projection content among the projection display areas is realized by the change of the relative position between the light source and the image display mechanism. The device has beneficialeffects that: the projection content can be projected to different projection display areas by adjusting the relative position between the light source and the image display mechanism; the projectiondevice is arranged on the washing machine, the display of the projection content in different positions of the washing machine is realized, and the device is convenient for the usage of users; the display position of the projection content can be controlled and changed by the arranged control device according to the operation of users, the following characteristic of the projection content is good, and the better experience feeling is provided for users.

Description

technical field [0001] The invention belongs to the field of washing machines, and in particular relates to a projection device applied to household appliances, a washing machine and a control method. Background technique [0002] The display area of ​​the existing washing machine is concentrated on the operation panel, which integrates display and operation on components such as program selection, function setting, and display screen. Due to the structure of the washing machine, the installation position and size of the operation panel are limited. The limited installation position of the operation panel limits the display area, and the size of the operation panel limits the size of the display area. At present, a display screen is usually used for display. In order to increase the area of ​​the display area, the size of the display screen is increased. However, the larger the size of the display screen, the higher the price, and the size and display content of the display ...
