Fig. 1A schematically shows a configuration diagram of a dishwasher according to an embodiment of the present invention, in which a control method for the dishwasher according to an embodiment of the present invention may be applied. Fig. 1B schematically shows a front view of the structure of a dishwasher according to an embodiment of the present invention. It should be understood that FIGS. 1A and 1B illustrate only one embodiment of the dishwasher 100 and are not intended to limit the shape, location, manner of installation and relationship of the parts of the dishwasher not relevant to the present invention;

as shown in fig. 1A and 1B, the dishwasher 100 may include a housing 1 and a washing mechanism 2 disposed inside the housing 1. The outer contour of the housing 1 may include, but is not limited to, a rectangular, cylindrical shape.

The washing means 2 may comprise an image acquisition device 21, a rack 22, a handling device 24 and a spray arm.

A rack 22 (e.g., a basket) may be secured inside the dishwasher 100 for holding dishes and the image acquisition device 21 may include a camera or an image sensor (e.g., an infrared sensor). The image acquisition device 21 can be arranged in a variety of orientations within the dishwasher 100. The processing device 24 may be electrically connected to the image acquisition device 21.

The image acquisition device 21 may be used to acquire images within the dishwasher 100 and the processing device 24 may be used to process the acquired images.

For example, after the dishes are placed on the rack 22, the image capturing device 21 may capture an image of the dishes on the rack 22. The processing device 24 can acquire the image and determine characteristics of the dishes placed within the dishwasher 100 to control the spray arms to wash the dishes according to the characteristics of the dishes.

Examples of processing device 24 may include, but are not limited to, a general purpose processor, a special purpose processor, a conventional processor, a Digital Signal Processor (DSP), a plurality of microprocessors, one or more microprocessors in association with a DSP core, a controller, a microcontroller, Application Specific Integrated Circuits (ASICs), Field Programmable Gate Arrays (FPGAs) circuits, any other type of Integrated Circuit (IC), a state machine, and the like.

In one example, a spray arm may be disposed at the bottom of the dishwasher 100, and the spray arm may be provided with spray holes, from which water may be sprayed upwards to provide a reaction force to rotate the spray arm while washing dishes. In another example, the spray arm may be disposed at the top within the dishwasher 100, or may include a top spray arm and a bottom spray arm.

In yet another example, the spray arm may take a rotatable form.

FIG. 1C schematically illustrates a schematic structural view of a washing mechanism of a dishwasher in accordance with an embodiment of the present invention; FIG. 1D schematically illustrates a partial structural view of the purge mechanism of FIG. 1C. Referring to fig. 1B to 1D, the washing mechanism 2 may further include a driving motor 23, and the driving motor 23 may be disposed at a lower side in the dishwasher 100, or may be disposed at a back side of the dishwasher 100, i.e., a side where the dishes are placed away from the user. The drive motor 23 may be connected to a spray arm 25. The spray arm 25 is provided with spray holes 251 communicated with the interior of the spray arm 25, and the spray holes 251 can be arranged on the spray arm 25 at intervals so that the spray arm 25 sprays a larger range. In one example, the spray arm 25 may be cylindrical, and the orifices 251 are spaced apart in the cross-section of the spray arm 25 and arranged in an array such that water ejected from the orifices 251 is emitted at an angle.

In an embodiment of the present invention, the dishwasher 100 may further include a water pressure transducer (not shown), a water heater (not shown), and a water valve (not shown). The water pressure transducer and water heater may be electrically connected to the processing equipment 24, and the water pressure transducer, water heater, and water valve may be internally connected and in communication with the spray arm 25. The connection of the spray arm 25 with the water pressure transmitter, the water heater, the water valve, and the driving motor 23 may be a direct connection or an indirect connection through an intermediate member.

The water valve can be used for controlling the water yield of the sprayed water, the water pressure transmitter can be used for controlling the water outlet pressure, the water heater can be used for controlling the water outlet temperature, and the driving motor 23 can be used for driving the spraying arm 25 to rotate. In one example, the spray arm 25 may be disposed at a central location within the dishwasher. The central position may be defined as a middle position of the plurality of racks 22 in the dishwasher 100 so as to cover dishes on the plurality of racks 22 when the spray arm 25 rotates, thereby saving space inside the dishwasher 100. Only a single spray arm 25 is needed to spray the tableware on a plurality of shelf 22, which saves the cost of design and material and brings more use space.

The water valves, water pressure transducer, water heater, and drive motor 23 may be controlled by the processing device 24. For example, the area of the rack 22 for placing dishes can be divided into four quadrants, namely, the first, second, third and fourth quadrants. Processing device 24 may control drive motor 23 to rotate spray arm 25 such that orifice 251 is directed toward any of the four quadrants. In addition, the treatment device 24 may also control a water valve to adjust the amount of water discharged from the nozzle hole 251 (or stop the water discharge).

In the embodiment of the present invention, the driving motor 23 may also drive the spray arm 25 to translate. When the spray arm 25 is translatable, the dishwasher 100 may further include a conversion mechanism (not shown) coupled between the drive motor 23 and the spray arm 25 that converts rotation of the drive motor 23 into translation of the spray arm 25.

In the present embodiment, the shelf 22 may include one or more shelves, such as two shelves. In the example of a two-level rack shown in the figures, the spray arm 25 may be located in the middle of the two racks 22 so that all dishes on the two racks 22 may be sprayed when the spray arm 25 is rotated.

In an embodiment of the present invention, the dishwasher 100 may further include a mounting bracket 26, and the spray arm 25 may be rotatably coupled to the mounting bracket 26. The mounting bracket 26 is fixed in position such that the spray arm 25 can rotate relative to the mounting bracket 26. the manner in which the mounting bracket 26 is fixed in position is not limited, as the mounting bracket 26 can be fixedly attached to the carrier 22 or elsewhere.

Because the dishwasher is a closed space, bacteria are easy to breed if the dishwasher is not used for a long time. For some users who are out of home frequently (e.g., on business trips or on vacations), it is necessary to monitor the sanitary condition of the dishwasher periodically and to clean it at a proper time. Fig. 2 shows a schematic flow diagram of a control method for a dishwasher according to an embodiment of the present invention. As shown in fig. 2, a control method for a dishwasher according to an embodiment of the present invention may include the following steps.

In step S201, it is determined that the dishwasher enters the self-supervision mode.

In embodiments of the present invention, there are a number of ways to determine that a dishwasher is entering a self-supervision mode (e.g., a vacation mode).

In one example, the self-supervision mode may be entered by a user setting. For example, a user may perform a corresponding operation on a control panel or key of a dishwasher prior to going out, in response to which the dishwasher enters a self-supervision mode. The user may input the length of time of the outgoing (i.e., the away-from-home time length) to the dishwasher, and if the output length of the outgoing exceeds a preset length of time, the dishwasher may enter the self-supervision mode. Examples of the preset time period may be, for example, 2 days, 3 days, and the like.

In another example, the dishwasher may automatically enter a self-supervision mode. Specifically, the dishwasher begins timing after the last operation, and may enter a self-supervision mode if the timed time does not receive any user operation (e.g., operating the control panel) or any operation instruction (e.g., receiving an operation instruction of another device through the communication network) within a preset time period. Examples of the preset time period may be, for example, 2 days, 3 days, and the like.

In yet another example, the dishwasher may include an image acquisition device for detecting whether a human being is active outside the dishwasher. If no human activity is detected for a preset length of time, the dishwasher may enter a self-supervision mode. In this example, examples of the preset time period may be, for example, 2 days, 3 days, and the like. Examples of image acquisition devices may include, but are not limited to, cameras, infrared detection devices.

For example, in the general case where a dishwasher is provided in a kitchen, if a person is frequently at home, an image acquisition device provided in the dishwasher may detect human body activities, such as entering and exiting the kitchen, more frequently. If the person is out for a long time, the image acquisition device cannot detect human body activity within a preset time, and in this case, the dishwasher can automatically enter a self-supervision mode.

In step S202, the dishwasher is periodically controlled to wash dishes in the dishwasher.

Specifically, after entering the self-supervision mode, the dishwasher may perform a washing of the dishes within the dishwasher at intervals. In one example, because the dishes have been previously washed, washing the dishes in the self-regulated mode requires only water, and may not require the addition of a detergent (e.g., dishwashing powder). In another example, dishwashers are located in different environments (e.g., wet areas), and even if previously washed, the dishware may develop mold "fuzz". The detergent may be added at intervals. For example, if no detergent was added for the last wash, detergent may be added for the current wash. Of course, the detergent may be added at the third washing without adding the detergent twice. In this embodiment, an example of the interval time (or referred to as a washing cycle) may be 5 to 15 days, and preferably, may be 7 days.

In an additional or alternative embodiment, whether detergent is added or not may be assisted by means of an image acquisition device. In particular, the above-described image acquisition device in a dishwasher may also be used for acquiring images within the dishwasher, or the dishwasher may further comprise a further image acquisition device (e.g. a camera) for acquiring images within the dishwasher. The processor of the dishwasher may determine whether there is an abnormality (e.g., mold growth, often referred to as "hair") on the dishware based on the image captured by the image capture device, and if it is determined that there is no abnormality based on the image, then no detergent may be added during the washing process. If it is judged from the image that there is an abnormality, a detergent may be added at the time of cleaning. In this embodiment, it is only necessary to add image capture and analysis functionality to the dishwasher to more accurately determine whether detergent is added to wash dishes in the self-supervision mode, thereby making the use of detergent more accurate.

In the embodiment of the present invention, the control method may further include: step S203, exiting the self-supervision mode.

In particular, in one example, the self-supervision mode may be exited by a user operation. For example, the user may activate a particular key on the dishwasher or activate any key or open the door of the dishwasher to exit the self-supervision mode. The self-supervision mode may be exited when the dishwasher receives a signal that triggers a particular key or any key or detects that the door of the dishwasher is opened. In another example, the dishwasher may exit the self-supervision mode when the image acquisition device detects human activity.

The control method provided by the embodiment of the invention can solve the maintenance problem of the dishwasher when the dishwasher is not used for a long time, so that a user can use clean tableware immediately after going home for a long time, the user requirement is met, and the user experience is improved.

Embodiments of the present invention also provide a processor, which may be used to execute the control method for the dishwasher in the above embodiments. The processor may be the master of the dishwasher, or may be a separate processor installed in the dishwasher.

Examples of a processor may include, but are not limited to, a general purpose processor, a special purpose processor, a conventional processor, a Digital Signal Processor (DSP), a plurality of microprocessors, one or more microprocessors in association with a DSP core, a controller, a microcontroller, Application Specific Integrated Circuits (ASICs), Field Programmable Gate Arrays (FPGAs) circuits, any other type of Integrated Circuit (IC), a state machine, and the like.

In particular, the processor may be configured to:

determining that the dishwasher enters a self-supervision mode;

the dishwasher is controlled to periodically wash dishes in the dishwasher.

In one example, the self-supervision mode may be entered by a user setting. For example, a user may perform a corresponding operation on a control panel or key of a dishwasher prior to going out, in response to which the dishwasher enters a self-supervision mode. The user may input the length of the outgoing time to the dishwasher, and the dishwasher may enter the self-supervision mode if the output length of the outgoing time exceeds a preset length of time. Examples of the preset time period may be, for example, 2 days, 3 days, and the like.

In another example, the dishwasher may automatically enter a self-supervision mode. Specifically, the dishwasher begins timing after the last operation, and may enter the self-supervision mode if the timed duration does not receive any user operation (e.g., operating the control panel) or any operation instruction (e.g., receiving an operation instruction of another device through the communication network) within a preset duration. Examples of the preset time period may be, for example, 2 days, 3 days, and the like.

In an embodiment of the present invention, the processor may be further configured to: exiting from the supervision mode.
