Description

Technical Field

[0001] This invention relates to the field of washing, and in particular to a washing device, a method for detecting overflow bubbles, an electronic device, and a storage medium thereof. Background Technology

[0002] As people's consumption levels rise, fully automatic washing machines have become an essential household appliance. Currently, fully automatic washing machines are very popular among consumers due to their high degree of automation, bringing convenience but also new problems.

[0003] Washing machines require detergent or washing powder to remove stains from clothes during the washing process. The mixture of detergent and water produces a large amount of foam, which can easily lead to overflow. In severe cases, this can cause component failure or damage. Even worse, overflowing foam can cause users to slip and fall, posing a safety hazard. Foam overflowing into the machine's wiring can also cause electrical components or circuit boards to malfunction, leading to short circuits and fires. During the rinsing stage, overflow can cause the machine to spin-dry while still wet, resulting in motor overheating and a sharp increase in current, creating a safety risk for users. Current technology typically detects foam during the draining and spin-drying stages based on changes in drum pressure or water level. Detecting foam during the washing process is either impossible or prohibitively expensive, making it difficult to accurately and promptly determine if overflow is present.

[0004] Therefore, it is necessary to develop a new method for detecting overflow bubbles in washing devices to solve the above problems. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, the present invention aims to provide a washing device and its foam overflow detection method, electronic device, and storage medium. During the washing process, a distance value is obtained through a sensing device, and the excessive foam is promptly and accurately determined based on the distance value, preventing foam overflow. This method can accurately and promptly obtain the amount of foam during the washing process and execute a defoaming process in a timely manner, effectively avoiding the risk of foam overflow.

[0025] Furthermore, determining whether a defoaming process needs to be executed based on the distance value also includes:

[0027] Furthermore, specifically including:

[0028] If a distance value can be collected within the third preset threshold, it is determined that the foam has reached the warning value, and the defoaming process begins.

[0029] If no distance value is collected within the third preset threshold, it is determined that the foam has not reached the warning value, and the distance value is continuously monitored.

[0030] Furthermore, the defoaming process includes the following steps before it begins:

[0031] Control the washing device to rotate, and obtain the distance value again;

[0032] Determine whether the distance values ​​are consistent before and after the washing device rotates;

[0033] If they match, then it is determined that there is foam inside the cylinder;

[0055] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0056] Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this invention.

[0057] The drawing numbers in this application are only used to distinguish the steps in the scheme and are not used to limit the execution order of the steps. The specific execution order is as described in the specification.

[0058] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0059] Figure 1 This is a flowchart of a foam overflow detection method for a washing device provided in Embodiment 1 of the present invention. Embodiment 1 of the present invention is applicable to real-time monitoring of foam during the washing process, so as to promptly execute the defoaming process and avoid foam overflow from the washing device causing damage to the washing device.

[0060] Example 1

[0061] like Figure 1 The overflow detection method of the washing device according to the present invention includes the following steps during the washing process: The washing device is equipped with a sensing device for collecting data from inside the drum.

[0062] S1: Obtain the distance value obtained by the sensor device through reflection from the environment inside the inner cylinder;

[0063] It should be noted that the distance value specifically includes:

[0064] The light source module of the sensing device emits a beam of light into the cylinder at a preset angle;

[0065] The reflected light beam is received by the receiving module of the sensing device;

[0066] The distance value is obtained based on the time difference between the emitted beam and the reflected beam.

[0067] The sensing device is a depth sensor that can collect distance values. The distance value represents the actual distance of each pixel from the depth sensor. It is similar to a grayscale image, but the difference is that the depth data reflects the real distance of each point on the object's surface from the sensing device.

[0068] The sensing device in this embodiment is a single-point Time-of-Flight (TOF) sensor. A TOF sensor works by continuously sending modulated light sources or pulses to a target object, then receiving the light reflected back from the target object. The distance to the target object is obtained by calculating the round-trip time of the modulated light source or probe light pulse. In this embodiment, the TOF sensor's light source module includes a structured light emitter and a laser emitter, which can simultaneously emit structured light and modulated laser light, which are then received by the TOF sensor to calculate depth data. This embodiment's TOF sensor fully combines TOF and structured light technologies, improving the measurement accuracy of TOF technology at close range. It overcomes the measurement limitations of TOF technology for black objects and low-reflectivity objects at close range, greatly improving the accuracy of the final output distance value and enhancing its anti-interference capabilities. This makes it suitable for more complex environments, broadening the product's applicability. Patent CN109889809A describes the structure of this TOF sensor in detail.

[0069] Because the TOF sensor can be fixedly installed inside the door glass, door seal, or lifting rib of the washing machine door, its spatial position is fixed, and the detection space is also fixed, ensuring the validity of the data collected by the sensor. Distance values ​​obtained through the TOF sensor do not require edge calibration, corner settings, or other functional settings, and can perform up to 9 million distance measurements per second with millimeter-level accuracy.

[0070] In a preferred embodiment, considering that the field of view of a single TOF sensor is usually between 60° and 90°, there is a large detection blind zone. Therefore, depth data can also be collected by several TOF sensors to make the results more accurate.

[0071] In this embodiment, the inner environment of the inner cylinder includes the inner cylinder wall, foam, and clothing. The light source module of the TOF sensor emits a light beam towards the foam in the inner cylinder at a preset angle, and the receiving module of the TOF sensor then receives the light beam reflected by the foam. The distance between the TOF sensor and the foam can be obtained based on the time of the emitted and reflected light beams, which is the distance value. The preset angle is the emission angle of the light beam emitted by the light source module of the TOF sensor.

[0072] S2: Determine whether the defoaming process needs to be executed based on the distance value.

[0073] It should be noted that, as Figure 2 As shown, determining whether to execute the defoaming process based on the distance value specifically includes:

[0074] S201: Determine whether the distance value is less than or equal to the first preset threshold;

[0075] S202: If the distance value is less than or equal to the first preset threshold, then start the defoaming process;

[0076] S203: If the distance value is greater than the first preset threshold, then reacquire the depth data.

[0077] In this embodiment, the first preset threshold is the distance between the sensor and the container when there is foam in the container and the foam is high. At this time, a defoaming process needs to be performed to defoam in time.

[0078] In another preferred embodiment, such as Figure 3 As shown, obtaining the distance value collected by the sensing device and obtained by reflection from the environment inside the inner cylinder also includes:

[0079] S204: The distance value includes multiple first distance values;

[0080] S205: The first distance value is the first distance value obtained by the sensor emitting light beams at different preset angles and reflecting off the environment inside the inner cylinder.

[0081] In this embodiment, as Figure 5 As shown, when the sensing device is installed on the door glass, the light source module of the depth sensor is controlled to emit light beams from different angles within the measurable range of the sensing device, so that the first distance value can be measured at multiple locations.

[0082] It should be noted that determining whether to execute the defoaming process based on the distance value specifically includes:

[0083] S206: Determine whether the collection points are on the same preset plane based on the first distance value;

[0084] S207: If they are on the same preset plane, the defoaming process will begin;

[0085] S208: If they are not on the same preset plane, the first distance value will be continuously monitored.

[0086] Specifically, such as Figure 4 As shown, determining whether the sampling points are on the same plane specifically includes:

[0087] S2061: Calculate the vertical distance between the sensor device and the foam based on the first distance value;

[0088] S2062: Determine whether the vertical distance is less than the second preset threshold;

[0089] S2063: If the vertical distance is less than the second preset threshold, then it is determined that they are on the same preset plane.

[0090] S2064: If the vertical distance is not less than the second preset threshold, then it is determined that they are not on the same preset plane.

[0091] It should be noted that, as Figure 6As shown, the vertical distance 'a' is obtained by using the cosine formula with the preset angle and the first distance value:

[0092] a=dcosα

[0093] Where α represents the preset angle, d is the first distance value, and the second preset threshold is the value at which the vertical distance meets the defoaming requirement. This threshold can be set according to the garment parameters and specific needs. The threshold can be a specific value or a range of values.

[0094] In another embodiment, combined Figure 7 , Figure 9 As shown, determining whether to perform a defoaming process based on the distance value also includes:

[0095] S209: Determine whether the foam has reached the warning value by using the distance value that can be collected within the third preset threshold.

[0096] The third preset threshold is the distance between the sensor and the foam when the foam volume is at its maximum; the third preset threshold is much smaller than the first preset threshold and the second preset threshold. This threshold can be a specific value or a range of values.

[0097] S210: If a distance value can be collected within the third preset threshold, it is determined that a large amount of foam has been generated, and the defoaming process is started.

[0098] S211: If no distance value is collected within the third preset threshold, it is determined that no large amount of foam has been generated, and the distance value is continuously monitored.

[0099] In some embodiments, such as Figure 9 The diagram illustrates that, for example, when foam has spread to the door glass, it indicates that the foam quantity has reached its maximum, i.e., the warning threshold, and a defoaming process urgently needs to be executed. Detecting foam at the door glass: This is done by measuring distance values ​​that can be collected near a specific depth on the washing machine's door glass to determine if a large amount of foam has been generated. Specifically, for example, all third-depth threshold values ​​(z) can be filtered out. k The distance values ​​form a set T Zk Determine set T Zk If a distance value exists, it can be determined that foam has been generated, and the defoaming process can be started.

[0100] It should be noted that z k It can be a point value or a value in z. k The range of values ​​formed near the depth of the door glass is used to characterize whether there is a reflection signal at the depth of the door glass; since the water reflection signal is extremely weak, the depth sensor can capture the foam with reflective ability on the water surface, and the clothing data can be filtered by rotating the cylinder to ensure the accuracy of the judgment.

[0101] like Figure 8 As shown, the defoaming process includes the following steps before it begins:

[0102] Control the washing device to rotate and obtain the distance value again;

[0103] Determine whether the distance values ​​before and after the washing device rotates are consistent;

[0104] If the distance values ​​are consistent, then it is determined that there is foam inside the cylinder;

[0105] If the distance values ​​are inconsistent, the distance values ​​will be continuously monitored.

[0106] The distance value detected by the sensor may also be the distance between the sensor and the clothing. Therefore, it is necessary to rotate the drum to filter out the clothing data in order to ensure the accuracy of the data.

[0107] Controlling the rotation of the washing machine drum includes, but is not limited to, controlling the inner drum to rotate forward, reverse, or alternately in both directions, as well as controlling the inner drum to perform forward and reverse rotation to create a shaking motion. During the operation of the inner drum, the depth distance can be continuously monitored. When the detected depth distance is within a second preset threshold, the defoaming process is initiated, improving the cleaning efficiency of the washing machine.

[0108] This application uses a sensor to obtain distance values ​​to accurately distinguish the foam situation inside the washing device drum. Based on the distance value, it can determine if there is too much foam, so as to promptly execute the defoaming process and avoid foam overflow from the washing device, which could cause damage. Timely execution of the defoaming process improves the cleaning efficiency of the washing device.

[0109] Example 2

[0110] A washing device is disclosed, along with a method for detecting overflow bubbles within the washing device. A detailed description of the method can be found in the corresponding descriptions in the above-described method embodiments, and will not be repeated here. In some embodiments, the washing device may be a washing machine, and in other embodiments, it may be a washer-dryer combo; this embodiment uses a pulsator washing machine as an example.

[0111] It should be noted that the sensor is installed inside the door glass of the washing machine, on the door seal, or inside the lifting rib.

[0112] Combination Figure 5 , Figure 9 As shown, the washing device includes an inner drum 1, a door 12, a door glass 11, and a sensor 2, with the door glass 11 mounted on the door 12. The washing device includes at least one sensor 2. The sensor acquires the distance value between the inner environment of the drum and the sensor itself, and determines whether a defoaming process needs to be performed based on the distance value.

[0113] In some alternative embodiments, the sensing device 2 is fixedly installed inside the door glass 11. The sensing device 2 continuously sends modulated light sources or pulses into the cylinder, and then receives the light returning from the inner cylinder. The distance to the foam 4 inside the cylinder is obtained by measuring the round-trip time of the modulated light source or probe light pulse. Since the sensing device 2 is fixedly installed inside the door glass, its spatial position is fixed, and the detection space is also fixed, ensuring the validity of the data collected by the sensor.

[0114] In some alternative embodiments, the sensing device 2 can also be mounted on the door seal. The sensing device 2 continuously sends modulated light sources or pulses into the cylinder, and then receives the light returning from the inner cylinder. The distance to the foam 3 inside the cylinder is obtained by measuring the round-trip time of the modulated light source or probe light pulse. Since the sensing device 2 is fixedly mounted on the door seal, its spatial position is fixed, and the detection space is also fixed, ensuring the validity of the data collected by the sensor.

[0115] In some alternative embodiments, the sensor 2 can also be installed inside the lifting rib. The sensor 2 measures the internal environment of the cylinder when it is in a specific position. Although the sensor 2 is fixedly installed inside the lifting rib, the position of the sensor is not fixed because the lifting rib rotates with the inner cylinder. Therefore, to ensure the validity of the data collected by the sensor, it is necessary to control the lifting rib to stop at a specific position before collecting distance values. For example, when the lifting rib containing the sensor 2 rotates to its highest position, the detection space of the sensor 2 is also fixed, ensuring the validity of the data collected by the sensor.

[0116] The sensing device in this embodiment is a Time-of-Flight (TOF) sensor, which can be used to measure distance and obtain a distance value. The light source integrated into the TOF sensor emits light pulses that illuminate the object. The object reflects the light pulses back to the camera. Based on the time required for the light pulses to travel, the distance between the object and the camera is determined, thereby obtaining the distance value.

[0117] When using a Time-of-Flight (TOF) sensor for data acquisition, up to 9 million distance measurements can be performed per second with millimeter-level accuracy. Compared to other sensing devices, TOF sensors are more economical, compact, and simple, allowing for easy installation and integration.
