Problems solved by technology

The projector is mainly composed of an optical system, ventilation equipment and circuits. Similar to a slide projector, it also uses the principle of convex lens imaging to realize the projection function, which can change the size of the real area. Change or switch the display area according to the operation used, and the user's interactive experience is poor

Embodiment 1

[0042] Such as figure 1 As shown, a split-screen projection device applied to household appliances includes a control device 100 and a split-screen projection display mechanism. The split-screen projection display mechanism can display projected content on different projection display areas. The split-screen projection display mechanism is operated and controlled to perform split-screen projection display to change the display area of ​​the projected content.

[0043] Although the volume of the household appliance is relatively large, the area used for display is concentrated on the operation panel, and the space of the operation panel is limited, so that the area of ​​the display area is smaller. By setting up a split-screen projection display mechanism, the display area is distributed in multiple display positions, so that the projection content is displayed on different projection display areas. When large-scale content is displayed on different projection display areas, ea...

Embodiment 2

[0057] Such as Figure 1-2 As shown, a washing machine using a split-screen projection device. The split-screen projection device includes a control device 100 and a split-screen projection display mechanism. The split-screen projection display mechanism performs split-screen projection to form projection display areas on different parts of the washing machine. The control device 100 According to the operation of the user, the projection display areas of different parts are controlled to display the projection content, so as to change the display position of the projection content on the washing machine.

[0058] The projected display area can be located on the control panel, observation window, door cover 401 , detergent box, tray base 402 and other positions.

[0059] Furthermore, the plurality of imaging areas correspond to the projection display areas of different parts of the washing machine, and the control device 100 displays the projection content in different imaging ...

Embodiment 3

[0072] A method for controlling a washing machine equipped with a split-screen projection device. The control device 100 controls the split-screen projection display mechanism to perform split-screen projection display according to user operations, so as to change the display position of the projected content.

[0073] Such as Figure 1-3 As shown, the image display mechanism includes three imaging areas, imaging area 1 201, imaging area 2 202, and imaging area 3 203, and the projection content displayed in imaging area 1 201 is projected on the door cover 401 of the washing machine through a split-screen projection device to form a projection The projection content displayed in the display area 1 301 and the imaging area 2 202 is projected on the dish base 402 of the washing machine through the split-screen projection device to form the projection display area 2 302, and the projection content displayed in the imaging area 3 203 is projected on the washing machine through the ...

Abstract

The invention belongs to the field of household electrical appliances, and relates to a split screen projection device applied to household electrical appliances, a washing machine and a control method. The split screen projection device includes a control device and a split screen projection display mechanism. The control device controls the split screen projection display mechanism to perform split screen projection display according to an operation of a user to achieve the effect that display contents are displayed at different display positions after being projected. The projection contents are displayed on the split screen through the arrangement of the split screen projection display mechanism. The control device controls the split screen projection display mechanism to project the projection contents to different display regions or display the projection contents on the different display regions according to the operation of the user, and so the following of the operation of theuser is realized. The projection contents are switched from one projection display region to other projection display regions for display, and so the switching of the projection display regions is realized. The projection contents are projected to a more easily observable part for the user or are projected to a larger space for display. The usage is more convenient and flexible, the following performance of the projection contents is good, and the user interaction experience is good.

Description

technical field [0001] The invention belongs to the field of household appliances, and in particular relates to a split-screen projection device, a washing machine and a control method applied to household appliances. 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 conten...
