Description

Technical Field

[0001] This application relates to the field of electronic technology, specifically to a cleaning liquid spraying control method, a surface cleaning device, and a storage medium. Background Technology

[0002] A surface cleaning device is a household appliance that provides cleaning functions, such as a window cleaning robot or a floor cleaning robot. Surface cleaning devices typically have a drive unit at their base, which propels the device across the surface to be cleaned. As the device moves across the surface, the cleaning unit wipes or sweeps it, achieving a cleaning effect.

[0003] To improve cleaning effectiveness, some surface cleaning devices are equipped with a cleaning liquid spraying unit (the cleaning liquid can be water or an aqueous solution containing detergent, etc.), such as a nozzle. When the surface cleaning device performs cleaning operations in the cleaning area, the surface to be cleaned can be wetted by the cleaning liquid spraying unit to improve the wiping effect of the cleaning unit.

[0004] However, in the existing technology, the spray angle of the cleaning liquid spraying unit is relatively narrow, which means that the width of the cleaning liquid spraying area cannot completely cover the width of the surface cleaning device, resulting in poor cleaning effect of the surface cleaning device.

[0005] It should be noted that the information disclosed in the background section of this application is intended only to enhance the understanding of the general background of this application, and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] In view of this, this application provides a cleaning liquid spraying control method, a surface cleaning device, and a storage medium to solve the problem in the prior art that the width of the cleaning liquid spraying area cannot cover the width of the surface cleaning device due to the narrow spraying angle of the cleaning liquid spraying unit, thus resulting in poor cleaning effect of the surface cleaning device.

[0015] In one possible implementation, performing a cleaning fluid spraying operation to the left of the walking direction of the surface cleaning device includes: controlling the cleaning fluid spraying unit of the surface cleaning device to rotate to the left by a third preset angle to perform a cleaning fluid spraying operation.

[0016] The step of performing a cleaning fluid spraying operation to the right of the direction of travel of the surface cleaning device includes: controlling the cleaning fluid spraying unit of the surface cleaning device to rotate to the right by a fourth preset angle to perform a cleaning fluid spraying operation.

[0017] In one possible implementation, the controlled surface cleaning device performs a cleaning fluid spraying operation according to a preset cleaning fluid spraying strategy, including:

[0018] Before the surface cleaning device performs the surface cleaning operation, the surface cleaning device is controlled to perform a cleaning liquid spraying operation according to a preset cleaning liquid spraying strategy;

[0019] Alternatively, during the surface cleaning operation, the surface cleaning device is controlled to perform a cleaning liquid spraying operation according to a preset cleaning liquid spraying strategy.

[0020] In one possible implementation, during the surface cleaning operation performed by the surface cleaning device, controlling the surface cleaning device to perform a cleaning liquid spraying operation according to a preset cleaning liquid spraying strategy includes:

[0021] During the surface cleaning operation, the surface cleaning device is controlled to spray cleaning liquid according to a preset cleaning liquid spraying strategy at preset time intervals.

[0022] In one possible implementation, during the surface cleaning operation performed by the surface cleaning device, controlling the surface cleaning device to perform a cleaning liquid spraying operation according to a preset cleaning liquid spraying strategy at preset time intervals includes:

[0023] When the area of ​​the surface to be cleaned is greater than a preset area threshold, during the surface cleaning operation, the surface cleaning device is controlled to perform a cleaning liquid spraying operation according to a preset time interval and a preset cleaning liquid spraying strategy.

[0028] In one possible implementation, during the surface cleaning operation performed by the surface cleaning device, controlling the surface cleaning device to perform a cleaning liquid spraying operation according to a preset cleaning liquid spraying strategy includes:

[0029] During the surface cleaning operation, if the humidity sensor detects that the humidity of the cleaning unit is lower than the preset humidity threshold, the surface cleaning device is controlled to perform a cleaning liquid spraying operation according to the preset cleaning liquid spraying strategy.

[0043] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0044] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0045] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0046] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0047] The surface to be cleaned in this application embodiment can be a non-horizontal surface, such as a framed window, a frameless window, or a wall; or a horizontal surface, such as a floor or a tabletop. When the surface to be cleaned is non-horizontal, the surface cleaning device is also equipped with a negative pressure mechanism, which allows the surface cleaning device to be adsorbed onto the surface. When the surface to be cleaned is horizontal, the surface cleaning device may or may not have a negative pressure mechanism. When a negative pressure mechanism is provided, it increases the pressure between the surface cleaning device and the surface to be cleaned, thereby increasing the friction between them and improving the cleaning effect.

[0048] The surface cleaning device involved in the embodiments of this application may be a square surface cleaning device (such as...). Figure 1 As shown), circular surface cleaning device (such as...) Figure 2 (as shown) or other product forms. Figure 1 The specific structure and working principle of the square surface cleaning device shown can be found in the description of Chinese Patent CN201580024976.5; Figure 2 The specific structure and working principle of the circular surface cleaning device shown can be found in the description of Chinese Patent CN201210185869.9. It should be noted that this application focuses on the cleaning liquid spraying control method of the surface cleaning device and does not limit its product form or movement method.

[0049] See Figure 3This diagram illustrates an application scenario provided by an embodiment of this application. For ease of explanation, mutually perpendicular X and Y directions are defined on the surface cleaning device. The X direction is the traveling direction of the surface cleaning device, and the Y direction is the width direction of the device's body. Furthermore, the traveling direction can also be referred to as the front of the surface cleaning device. For example, when the surface cleaning device travels along the X direction, the X direction is the front of the surface cleaning device; when the surface cleaning device travels in the opposite direction of X, the opposite direction of X is the front of the surface cleaning device.

[0050] The cleaning unit is typically located at the bottom of the surface cleaning device, and its width is the same as the width of the device's body, i.e., W1. This means that as the surface cleaning device moves forward in the direction of travel, it can wipe the surface to be cleaned within a width of W1.

[0051] To improve cleaning effectiveness, some surface cleaning devices are equipped with a cleaning liquid spraying unit (the cleaning liquid can be water or an aqueous solution containing detergent, etc.), such as a nozzle. When the surface cleaning device performs cleaning operations in the area to be cleaned, the cleaning liquid can be sprayed in front of the surface cleaning device through the cleaning liquid spraying unit, thereby wetting the surface to be cleaned and the cleaning unit, thus improving the wiping effect of the cleaning unit.

[0052] However, in related technologies, the spray angle of the cleaning fluid spraying unit is relatively narrow, meaning the width of the cleaning fluid spray area cannot completely cover the width of the surface cleaning device, resulting in poor cleaning performance. For example, in... Figure 3 In the application scenario shown, the width of the surface cleaning device is W1, and the width of the cleaning liquid spraying area is W2. Since W2 is smaller than W1, when the surface cleaning device moves forward, the two sides of the cleaning unit (the area beyond the width W2 of the cleaning liquid spraying area) cannot be wetted by the cleaning liquid, resulting in poor cleaning effect of the surface cleaning device.

[0053] To address the aforementioned problems, this application provides a method for controlling the spraying of cleaning fluid in a surface cleaning device. The method includes controlling the surface cleaning device to perform a cleaning fluid spraying operation according to a preset cleaning fluid spraying strategy. This strategy includes performing at least two cleaning fluid spraying operations at different angles within a preset angle range, such that the width of the cleaning fluid spraying area covers the width of the surface cleaning device's body. In this application embodiment, even when the spraying angle of the cleaning fluid spraying unit is narrow, the width of the cleaning fluid spraying area can still cover the width of the surface cleaning device's body, thereby improving the cleaning effect of the surface cleaning device.

[0054] It should be further explained that "the width of the cleaning liquid spraying area covers the width of the surface cleaning device" in the embodiments of this application means that the projection of the cleaning liquid spraying area in the width direction of the surface cleaning device can cover the width of the surface cleaning device.

[0055] In one possible implementation, the width of the cleaning fluid spray area completely overlaps with the width of the surface cleaning device's body; that is, the projection of the cleaning fluid spray area onto the width of the surface cleaning device completely overlaps with the width of the device's body. It is understood that if the width of the cleaning fluid spray area is greater than the width of the surface cleaning device's body, some of the sprayed area will not be wiped by the cleaning unit, potentially resulting in cleaning fluid residue on the surface to be cleaned. In this embodiment, the width of the cleaning fluid spray area completely overlaps with the width of the surface cleaning device's body, which avoids cleaning fluid residue on the surface to be cleaned and further improves the cleaning effect of the surface cleaning device.

[0056] See Figure 4 This is a schematic diagram of a cleaning liquid spraying strategy provided in an embodiment of this application. Figure 4 As shown, it mainly includes the following steps.

[0057] Step S401: Perform a cleaning fluid spraying operation once to the left of the direction of travel of the surface cleaning device;

[0058] Step S402: Perform a cleaning fluid spraying operation in the direction of travel of the surface cleaning device;

[0059] Step S403: Perform a cleaning fluid spraying operation to the right of the direction of travel of the surface cleaning device.

[0060] In other words, in this embodiment of the application, a cleaning liquid spraying operation is performed once to the left of the walking direction, once to the right of the walking direction, and once to the left of the walking direction. By performing three cleaning liquid spraying operations, the width of the cleaning liquid spraying area is expanded, thereby ensuring that the width of the cleaning liquid spraying area covers the width of the surface cleaning device.

[0061] Of course, those skilled in the art can perform more or fewer cleaning fluid spraying operations and set other cleaning fluid spraying directions according to actual needs to meet the requirement that "the width of the cleaning fluid spraying area covers the width of the surface cleaning device body". This application embodiment does not impose any limitations on this.

[0062] Furthermore, this application embodiment does not restrict the execution order of steps S401-S403. That is, the execution order of steps S401-S403 can be arbitrarily adjusted. For example, they can be executed in the order of steps S403, S402, and S401; or in the order of steps S402, S401, and S403, etc.

[0063] In one possible implementation, the cleaning fluid spraying unit is fixedly connected to the main body, meaning the spraying direction of the cleaning fluid spraying unit is not adjustable. In this application scenario, the spraying direction of the cleaning fluid can be adjusted by rotating the main body of the surface cleaning device.

[0064] See Figure 5 This is a schematic diagram illustrating another application scenario provided by an embodiment of this application. For example... Figure 5 As shown, at time T1, the surface cleaning device is controlled to rotate to the left by a first preset angle to perform one cleaning fluid spraying operation; at time T2, the surface cleaning device is controlled to face the walking direction to perform one cleaning fluid spraying operation (i.e., the surface cleaning device does not need to rotate); at time T3, the surface cleaning device is controlled to rotate to the right by a second preset angle to perform one cleaning fluid spraying operation. Through these three cleaning fluid spraying operations, the width of the cleaning fluid spraying area covers the width of the surface cleaning device's body.

[0065] It should be noted that, in the embodiments of this application, the first preset angle and the second preset angle refer to the angles relative to the walking direction.

[0066] In another possible implementation, the angle of the cleaning fluid spraying unit on the machine body is adjustable, meaning the spraying direction of the cleaning fluid spraying unit is adjustable. In this application scenario, the spraying direction of the cleaning fluid can be adjusted by changing the angle of the cleaning fluid spraying unit.

[0067] See Figure 6 This is a schematic diagram illustrating another application scenario provided by an embodiment of this application. For example... Figure 6 As shown, at time T1, the cleaning fluid spraying unit of the surface cleaning device is controlled to rotate to the left by a third preset angle to perform one cleaning fluid spraying operation; at time T2, the surface cleaning device is controlled to perform one cleaning fluid spraying operation in the direction of travel (i.e., the cleaning fluid spraying unit does not need to rotate); at time T3, the cleaning fluid spraying unit of the surface cleaning device is controlled to rotate to the right by a fourth preset angle to perform one cleaning fluid spraying operation. Through these three cleaning fluid spraying operations, the width of the cleaning fluid spraying area covers the width of the surface cleaning device's body.

[0068] It should be noted that in the embodiments of this application, the cleaning liquid spraying unit is oriented towards the walking direction by default, and the third preset angle and the fourth preset angle refer to the angles relative to the walking direction.

[0069] In one possible implementation, before the surface cleaning device performs the surface cleaning operation, the surface cleaning device is controlled to perform a cleaning liquid spraying operation according to a preset cleaning liquid spraying strategy; or, during the surface cleaning operation, the surface cleaning device is controlled to perform a cleaning liquid spraying operation according to a preset cleaning liquid spraying strategy.

[0070] It is understandable that after the surface cleaning device completes the cleaning liquid spraying operation according to the preset cleaning liquid spraying strategy, the cleaning liquid on the cleaning unit will gradually be consumed as the surface cleaning device works, causing the humidity of the cleaning unit to gradually decrease. In order to ensure that the cleaning unit always maintains a suitable humidity, in this embodiment, during the surface cleaning operation, the surface cleaning device is controlled to perform the cleaning liquid spraying operation according to the preset cleaning liquid spraying strategy at preset time intervals. For example, the surface cleaning device is controlled to perform the cleaning liquid spraying operation according to the preset cleaning liquid spraying strategy once every 2 minutes or 3 minutes. It should be noted that those skilled in the art can set this time interval according to actual needs, and this embodiment does not impose specific limitations on it.

[0071] It is understandable that when the area of ​​the surface to be cleaned is small, performing a single cleaning fluid spraying operation according to the preset cleaning fluid spraying strategy is sufficient to ensure the humidity of the cleaning unit throughout the cleaning process. However, when the area of ​​the surface to be cleaned is large, it is necessary to control the surface cleaning device to perform multiple cleaning fluid spraying operations according to the preset cleaning fluid spraying strategy at preset time intervals. Therefore, in this embodiment, before performing the cleaning operation, the surface cleaning device can first detect the area of ​​the surface to be cleaned. When the area of ​​the surface to be cleaned is greater than a preset area threshold, during the surface cleaning operation, the surface cleaning device is controlled to perform a cleaning fluid spraying operation according to the preset cleaning fluid spraying strategy at preset time intervals. Conversely, when the area of ​​the surface to be cleaned is less than the preset area threshold, the surface cleaning device is controlled to perform a single cleaning fluid spraying operation according to the preset cleaning fluid spraying strategy only before performing the surface cleaning operation.

[0072] Understandably, besides cleaning time, the cleaning area and walking distance also reflect the degree of cleaning fluid consumption on the cleaning unit. Therefore, in one possible implementation, during the surface cleaning operation, the surface cleaning device is controlled to perform a pre-set cleaning fluid spraying strategy according to a preset cleaning area or walking distance. For example, the surface cleaning device is controlled to perform a cleaning fluid spraying operation once for every 1 square meter or 2 square meters cleaned; or, the surface cleaning device is controlled to perform a cleaning fluid spraying operation once for every 5 meters or 8 meters walked.

[0073] As mentioned above, when the area of ​​the surface to be cleaned is small, performing a single cleaning fluid spraying operation according to the preset cleaning fluid spraying strategy is sufficient to ensure the humidity of the cleaning unit throughout the cleaning process. However, when the area of ​​the surface to be cleaned is large, it is necessary to control the surface cleaning device to perform multiple cleaning fluid spraying operations according to the preset cleaning fluid spraying strategy at preset time intervals. Therefore, in this embodiment, before performing the cleaning operation, the surface cleaning device can first detect the area of ​​the surface to be cleaned. When the area of ​​the surface to be cleaned is greater than a preset area threshold, during the surface cleaning operation, the surface cleaning device is controlled to perform a cleaning fluid spraying operation according to the preset cleaning area or travel distance. Conversely, when the area of ​​the surface to be cleaned is less than the preset area threshold, the surface cleaning device is controlled to perform a single cleaning fluid spraying operation according to the preset cleaning fluid spraying strategy only before performing the surface cleaning operation.

[0074] In one possible implementation, the surface cleaning device is also equipped with a humidity sensor, which can detect the humidity of the cleaning unit. Therefore, the timing of the cleaning fluid spraying operation can be determined by the detection signal from the humidity sensor. Specifically, during the surface cleaning operation, if the humidity sensor detects that the humidity of the cleaning unit is lower than a preset humidity threshold, the surface cleaning device is controlled to perform a cleaning fluid spraying operation according to a preset cleaning fluid spraying strategy.
