[0031] Different home environments necessitate different dishwasher installation methods, and dishwashers mostly display programs according to a predetermined scheme, which does not change based on the installation method. To address this issue, this application provides a dishwasher program display control method. Specifically, the dishwasher installation methods include recessed installation and non-recessed installation. Recessed installation involves installing the dishwasher inside a cabinet, hidden below the countertop. Typically, the display screen is located on the top surface of the dishwasher; therefore, recessed installation will obstruct the display screen. (See appendix...) Figure 2 , Figure 2 This is a schematic flowchart illustrating the main steps of a dishwasher program display control method according to an embodiment of this application. Optionally, the above method can be executed by the dishwasher's computer board, such as... Figure 2 As shown, the method mainly includes the following steps S202 to S206:

[0032] Step S202: When the dishwasher is powered on for the first time, obtain the first distance between the display screen and the obstacle directly opposite the display screen.

[0033] In this embodiment, the first power-on refers to the first power-on after the dishwasher is installed. At this time, the dishwasher is determined to be either embedded or non-embedded by measuring a first distance between the display screen and the obstacle directly opposite the display screen, and comparing this first distance with a first preset threshold. Specifically, if the first distance is greater than the first preset threshold, the dishwasher is determined to be non-embedded; if the first distance is less than or equal to the first preset threshold, the dishwasher is determined to be embedded. It should be noted that the first preset threshold can be flexibly adjusted by those skilled in the art according to the application scenario, and this embodiment does not impose specific limitations on this comparison.

[0034] In one implementation, the first preset threshold is, for example, 10cm. When the first distance between the display screen and the obstacle directly opposite the display screen is less than or equal to 10cm, the dishwasher is determined to be an embedded installation; otherwise, it is a non-embedded installation.

[0035] In step S204, in response to the first distance being greater than a first preset threshold, the display screen is controlled to show the dishwasher program.

[0036] In this embodiment, if the first distance is greater than a first preset threshold, meaning the dishwasher is not embedded and the display screen is not obstructed, then the display screen is controlled to show the dishwasher program to the user. The dishwasher program includes the functions and parameters currently being executed by the dishwasher. For example, some commonly used functions and parameters of the dishwasher program are listed below: functions include washing, disinfection, drying, pre-rinse, and instant wash; parameters include time, temperature, fan speed, water level, etc.

[0037] In one embodiment, the aforementioned distance can be measured by installing an infrared sensor, a vision sensor, a depth camera, or similar device on the dishwasher.

[0038] In step S206, in response to the first distance being less than or equal to the first preset threshold, the projection device is controlled to project the dishwasher program onto the preset area.

[0039] In this embodiment, if the first distance is less than or equal to the first preset threshold, i.e. the dishwasher is embedded and the display screen is blocked, the projection device can be controlled to project the dishwasher program onto the preset area.

[0040] In one embodiment, the projection device can intuitively display information such as the functions and parameters of the dishwasher program to the user through images, charts, etc., so that the user can keep track of the washing progress at any time.

[0041] In one implementation, the preset area can be an area such as the floor, walls, or furniture surfaces near the dishwasher.

[0042] In one implementation, regardless of the dishwasher's installation method, the display screen and projection device can be controlled to simultaneously display the dishwasher program.

[0043] Based on steps S202 to S206 above, by obtaining the first distance between the user's display screen and the obstacle after the dishwasher is installed, and controlling the display screen or projection device to display the dishwasher program according to the relationship between the first distance and the first preset threshold, the purpose of enabling the dishwasher program display to adapt to different installation methods is achieved, thus solving the problem that the dishwasher program display cannot be adaptively adjusted according to different installation methods.

[0044] In one embodiment of this application, after step S204 described above, the following step S205 may be further included:

[0045] Step S205: In response to the first distance being greater than the first preset threshold, the projection device is turned off.

[0046] In this embodiment, if the first distance is greater than the first preset threshold, it can be determined that the dishwasher is installed in a non-embedded manner. According to step S204 above, the dishwasher displays the dishwasher program to the user through the display screen. Therefore, the projection device can be turned off, thereby achieving the purpose of energy saving and environmental protection.

[0047] In one embodiment of this application, after step S206 described above, the following step S207 may be further included:

[0048] In step S207, in response to the first distance being less than or equal to the first preset threshold, the display screen is controlled to display the dishwasher program with low energy consumption or the display screen is turned off.

[0049] In this embodiment, if the first distance is less than or equal to the first preset threshold, it can be determined that the dishwasher is installed in an embedded manner. According to step S206 above, the dishwasher program is then projected onto the preset area by the projection device. Therefore, the display screen can be turned off or controlled to display the dishwasher program with low energy consumption, such as displaying only a portion of the program. The specific display content can be selectively set by the user.

[0050] In one embodiment of this application, step S206 may further include steps S2062 to S2066:

[0051] Step S2062: Detect the second distance between the user and the projection device.

[0052] In this embodiment, when using a projection device to project the dishwasher program, it is necessary to detect the distance between the user and the projection device, i.e., the second distance, and determine the projection area based on the relationship between the second distance and a second preset threshold.

[0053] In step S2064, in response to the second distance being greater than the second preset threshold, the projection device is controlled to project the dishwasher program onto the preset area.

[0054] In this embodiment, if the second distance is greater than the second preset threshold, it means that there is enough distance between the user and the dishwasher to project the program. Therefore, the projection device is controlled to project the dishwasher program onto a preset area, such as projecting the program onto the ground in front of the dishwasher.

[0055] In one embodiment, the second preset threshold can be set to 1 meter. It is understood that the second preset threshold can be flexibly adjusted by those skilled in the art according to the application scenario. This embodiment does not impose any specific limitations.

[0056] Step S2066: In response to the second distance being less than or equal to the second preset threshold, adjust the area projected by the projection device.

[0057] In this embodiment, if the second distance is less than or equal to the second preset threshold, it means that the distance between the user and the dishwasher is insufficient to project the program. At this time, the area projected by the projection device can be adjusted, such as controlling the projection device to project the dishwasher program onto the ground, wall, cabinet door, or other areas to the side of the user.

[0058] In one embodiment of this application, step S2066 may further include steps S20662 and S20664:

[0059] Step S20662: Obtain the angle between the user and the projection device.

[0060] In this embodiment, in order to determine where to project the program when the second distance is insufficient, the angle between the user and the projection device can be obtained.

[0061] Step S20664: Adjust the area projected by the projection device based on the angle and the second distance.

[0062] In this embodiment, the area projected by the projection device is adjusted based on the second distance and the angle between the user and the projection device. For example, assuming the user is determined to be in front of the left side of the projection device based on the angle, the projection device can be controlled to project the program onto the ground in front of the right side of the projection device.

[0063] In one implementation, the second distance is denoted as n, the second preset threshold is denoted as n1, and when n > n1, the dishwasher program is projected onto the ground in front of the projection device. The third preset threshold is denoted as n0. Taking n1 = 1 meter and n0 = 0.3 meters as an example, when n0 ≤ n ≤ n1, it is determined whether the user is directly in front of the dishwasher. If the user is directly in front of the dishwasher, the program is projected onto the side cabinet door of the dishwasher or the adjacent wall; if the user is not directly in front of the dishwasher or n < n0, the program is projected onto the adjacent countertop of the dishwasher.

[0064] In one embodiment of this application, step S207 may be further included after step S206, specifically including the following steps S2071 and S2072:

[0065] Step S2071: Obtain the current time and the light intensity of the environment around the dishwasher.

[0066] Step S2072: Adjust the brightness of the projection device based on the current time and light intensity.

[0067] In this embodiment, the projection brightness of the projection device can be adjusted based on the time and light intensity obtained in step S2071. For example, the projection brightness can be increased at noon when the light intensity is high, thereby avoiding the problem of unclear projection and the user being unable to see clearly.

[0068] In one embodiment of this application, step S206 may further include the following steps S2068 and S2070:

[0069] Step S2068: Control the projection device to project the dishwasher program onto the preset area in the form of symbols and / or icons.

[0070] In this embodiment, the projection device can display the program to the user in the form of text, numbers, graphics, icons, etc., for example, using a predefined series of numbers or graphics to represent different functions of the dishwasher program.

[0071] Step S2070: Control the projection device to project different types of dishwasher programs onto the preset area using different colored lights.

[0072] In this embodiment, different colors of the projection can also be used to distinguish different types of programs. For example, when the dishwasher is washing, the projection is blue; when it is drying, the projection is yellow.

[0073] In implementing the technical solution of this application, by obtaining the first distance between the user's display screen and an obstacle after the dishwasher is installed, and controlling the display screen or projection device to display the dishwasher program based on the relationship between the first distance and a first preset threshold, the purpose of enabling the dishwasher program display to adapt to different installation methods is achieved. By detecting the second distance between the user and the projection device, and projecting the dishwasher program onto a preset area or adjusting the area projected by the projection device based on the relationship between the second distance and a second preset threshold, the display effect of the program is optimized. By adjusting the brightness of the projection device, turning off the projection device, and controlling the display screen to operate with low energy consumption, the purpose of saving energy is achieved.

[0074] In one application scenario example of this application, Figure 3 This is a schematic diagram of the overall steps of a dishwasher program display control method according to an embodiment of this application. Figure 3 As shown, the method mainly includes the following steps S301 to S308:

[0075] Step S301: The dishwasher is powered on for the first time.

[0076] Step S302: Detect the distance m between the top of the dishwasher and the obstacle. Optionally, the display screen is located at the top of the dishwasher by default, and distance m is the initial distance between the display screen and the obstacle.

[0077] Step S303: Determine whether m ≤ m0 is true. Here, m0 is the first preset threshold. If m ≤ m0 is not true, proceed to step S304; otherwise, proceed to step S305.

[0078] Step S304: The computer board displays normally, and the projection light is turned off. Optionally, the display screen is usually integrated with the computer board. When m≤m0 is not true, it is determined that the dishwasher is a non-embedded installation. In this case, the computer board displays normally, and the projection light (projection device) is turned off, that is, only the display screen is used to display the program to the user.

[0079] Step S305: The computer board activates the power-saving mode and turns on the floor lamp. Optionally, when m≤m0 is true, it is determined that the dishwasher is installed in a built-in manner. At this time, the floor lamp is turned on to display the program to the user through projection. Activating the power-saving mode on the computer board can also be achieved by turning off the display screen to reduce the energy consumption of the computer board.

[0080] Step S306: Determine whether the user distance n > n1 is true. Here, n represents the second distance and n1 represents the second preset threshold. If n > n1 is true, proceed to step S307; otherwise, proceed to step S308.

[0081] Step S307: Project the dishwasher program onto the first area. Optionally, when n > n1, the program can be projected onto the first area, such as the floor in front of the dishwasher.

[0082] Step S308: Project the dishwasher program onto the second area. Optionally, when n≤n1, the program can be projected onto the second area, such as the side wall or cabinet door of the dishwasher.
