Description

Technical Field

[0001] This invention belongs to the field of cleaning equipment technology, specifically, it relates to a washing machine and its control method. Background Technology

[0002] Washing machines are machines that use electric power to generate mechanical force to clean clothes. For clothes such as shirts, the collar and cuffs are generally dirtier than other areas. However, existing washing machines are not very effective at cleaning these areas during the washing process.

[0003] In existing technologies, ultrasonic washing is often required to achieve the desired result by adding an ultrasonic washing function to the washing machine.

[0004] For example, Chinese Patent Application No. CN200520069251.1 discloses a washing machine with a local ultrasonic washing device, including a washing machine body and an ultrasonic washing device. The ultrasonic washing device consists of an ultrasonic generator, a transducer, a device housing, and a transducer base. The ultrasonic generator is installed in a computer board and connected to the transducer. The transducer is installed on the base inside the device housing and is pressed down by a cover plate. The ultrasonic washing device is fixed by a positioning support and is installed at the rear of the washing machine's worktable via the positioning support.

[0005] Chinese patent application number CN2017101131757 discloses a partial cleaning structure for clothing and a washing machine. The partial cleaning structure for clothing is detachably mounted on the washing machine tray and connected to the washing machine's water inlet / detergent box. The partial cleaning structure for clothing includes a pressure plate and a support plate. The pressure plate includes an ultrasonic transducer, and the support plate includes a water inlet cavity. The shape of the pressure plate matches the support plate. After being pressed towards the support plate, a narrow slit is formed between them to clamp the part of the clothing to be washed, clamping the clothing and ultrasonically cleaning the part to be washed.

[0006] While the above solution addresses the issue of washing machines being unable to clean heavily soiled areas to some extent, adding ultrasonic cleaning to the outside of the washing machine undoubtedly increases its cost and reduces its market competitiveness.

[0007] In view of this, the present invention is proposed. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a washing machine that generates a start signal to start the detergent dispensing device or the water outlet component only when the detection device detects that the signal of the laundry approaching for a duration exceeding a certain set threshold, thereby avoiding the detergent dispensing device and the water outlet component being accidentally triggered.

[0009] Another object of the present invention is to provide a control method for a washing machine.

[0010] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

After a set delay time, it then generates a start signal to activate the detergent dispensing device.

[0025] Alternatively, after the detection device detects a signal that the laundry is approaching, it generates a start signal to activate the detergent dispensing device. After a set delay time, it then generates a start signal to activate either the detergent dispensing device or the water outlet assembly.

[0026] Furthermore, the detection device is an infrared sensing unit or a position sensor.

[0035] A drive mechanism for driving the liquid pump and the gas pump is configured to receive a signal to start / stop the detergent dispensing device.

[0036] Furthermore, an opening is provided on the side wall of the clothing inlet, through which the liquid outlet pipe and the water outlet pipe of the water outlet assembly are housed in the tray or extend out of the side wall of the clothing inlet.

[0037] A control method for a washing machine, applied to the washing machine as described above, includes the following steps:

[0038] S1, The detection device detects a signal that the laundry is approaching;

[0039] S2, determine whether the duration of the signal from the approaching clothes exceeds the set threshold. If yes, proceed to step S3; otherwise, standby.

[0040] S3, generate a start signal to start the detergent dispensing device or the water outlet component;

[0041] S4. Obtain the current state of the washing machine and determine whether the washing machine is currently running. If yes, proceed to step S5; otherwise, proceed to step S6.

[0042] S5, invalidate the start signal for starting the detergent dispensing device or the water outlet assembly;

[0043] S6, send a start signal to the detergent dispensing device or send a start signal to the water outlet assembly to clean the clothes to be washed;

[0044] S7, the user determines whether the laundry is clean. If yes, the user moves the laundry away from the detection device. If no, the user returns to step S1.

[0045] A control method for a washing machine, applied to the washing machine as described above, includes the following steps: S1, a detection device detects a signal that the laundry is approaching;

[0046] S2, determine whether the duration of the signal from the approaching clothes exceeds the set threshold. If yes, proceed to step S3; otherwise, standby.

[0047] S3, generate a start signal to start the detergent dispensing device or the water outlet component;

[0048] S4. Obtain the current state of the washing machine and determine whether the washing machine is currently running. If yes, proceed to step S5; otherwise, proceed to step S7.

[0049] S5, determine whether the washing machine is currently in the main wash stage. If yes, determine whether the user has confirmed that detergent or water has been sprayed. If yes, proceed to step S6; otherwise, proceed to step S7.

[0051] S7, invalidate the start signal for starting the detergent dispensing device or the water outlet assembly.

[0052] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0053] 1. The present invention provides a detergent dispensing device and a water outlet assembly that spray detergent and water respectively on the tray base, and controls whether the device is activated by a detection device. During the local cleaning process, the process of wetting clothes and adding detergent can be carried out alternately, thereby improving the cleaning effect on local areas.

[0054] 2. The present invention will only generate a start signal to start the detergent dispensing device or the water outlet component when the detection device detects that the signal of the laundry approaching for a duration exceeding a certain set threshold, so as to avoid the detergent dispensing device and the water outlet component being triggered accidentally.

[0055] 3. This invention only requires one detection device to control the water outlet component and detergent dispensing device, reducing the number of washing machine parts, simplifying assembly, and saving equipment costs.

[0056] 4. This invention utilizes a detergent dispensing device and a water outlet assembly to introduce water and detergent into the washing tub during the main wash stage of the washing machine, making it convenient for users to operate and improving the user experience.

[0057] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0066] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0067] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0068] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0069] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0070] like Figures 1 to 6 As shown, the present invention provides a washing machine, including a housing 1, a tub assembly disposed inside the housing 1, and a tray base 2 disposed on the top of the housing 1. The tray base 2 has a clothes inlet 3, which corresponds to the top opening of the tub assembly, and the tray base 2 is also provided with a cover 9 for opening and closing the clothes inlet 3.

[0071] The washing machine also includes a detergent dispensing device 4 and a water outlet assembly 5. The detergent dispensing device 4 is connected to the tray 2 and is used to spray detergent into the clothes inlet 3. The water outlet assembly 5 is connected to the tray 2 and is used to spray water into the clothes inlet 3.

[0072] It can be seen that the detergent dispensing device 4 and water outlet component 5 mentioned above are different from the detergent dispensing device 4 and water inlet component provided on conventional washing machines for dispensing detergent into the drum assembly. They are devices for spraying detergent and water when cleaning a local area of ​​the laundry 10, so that the washing machine mentioned above has the function of cleaning a local area.

[0073] The washing machine also includes a detection device 6, which is configured to generate a start signal to activate the detergent dispensing device 4 or the water outlet assembly 5 after the duration of a signal indicating that the laundry 10 is approaching exceeds a set threshold.

[0074] The above solution involves installing a detergent dispensing device 4 and a water outlet assembly 5 on the base 2, respectively, to spray detergent and water. A detection device 6 controls their activation. During localized cleaning, wetting the clothes and adding detergent can be performed alternately, improving the cleaning effect on specific areas. Furthermore, an activation signal for the detergent dispensing device 4 or the water outlet assembly 5 is only generated when the signal duration of the garment 10 approaching exceeds a set threshold, increasing the safety of controlling the detergent dispensing device 4 and the water outlet assembly 5.

[0075] In detail, the detergent dispensing device 4, the water outlet assembly 5, and the detection device 6 are all mounted on the tray base 2. Therefore, when the user puts clothes into the tub assembly, they will inevitably pass through the detection device 6. To prevent the detection device 6 from being accidentally triggered, the present invention limits the duration of the signal detected by the detection device 6. Only when the duration exceeds the set threshold will the detection device 6 generate a start signal to activate the detergent dispensing device 4 or the water outlet assembly 5. Otherwise, the detection device 6 will not generate a start signal to activate the detergent dispensing device 4 or the water outlet assembly 5.

[0076] The above solution makes the logic of the washing machine of the present invention more reasonable in the process of controlling the water outlet component 5 and the detergent dispensing device 4, and reduces the possibility of being triggered erroneously.

[0077] In some embodiments of the present invention, the washing machine further includes a control unit connected to the detection device 6, configured to determine the current state of the washing machine after receiving a start signal to start the detergent dispensing device 4 or the water outlet assembly 5. If the washing machine is in standby mode at the current time, the control unit sends the start signal to start the detergent dispensing device 4 or the start signal to start the water outlet assembly 5 to start the water outlet assembly 5.

[0078] In detail, to further enhance the safety of the detergent dispensing device 4 and the water outlet assembly 5, after receiving a signal to activate the detergent dispensing device 4 or the water outlet assembly 5, the present invention does not immediately activate the detergent dispensing device 4 or the water outlet assembly 5. Instead, it determines the current state of the washing machine. If the washing machine is currently in standby mode, i.e., the tub assembly is not performing a washing task, and it is confirmed that it is safe to use the detergent dispensing device 4 or the water outlet assembly 5 at this time, then the activation signal to activate the detergent dispensing device 4 or the activation signal to activate the water outlet assembly 5 will be sent to the detergent dispensing device 4 or the water outlet assembly 5.

[0079] In some embodiments of the present invention, if the washing machine is currently in the running state, that is, the washing tub is performing a washing task, there may be some safety hazards if the detergent dispensing device 4 or the water outlet assembly 5 is used. For example, the clothes to be washed 10 may rotate with the washing tub, or the water flow may be too large, causing the water level in the washing tub to exceed the maximum water level and overflow.

[0080] At this time, even if the control unit receives a start signal to start the detergent dispensing device 4 or the water outlet assembly 5, it should not send the start signal to the detergent dispensing device 4 or the water outlet assembly 5, but should invalidate the start signal to start the detergent dispensing device 4 or the water outlet assembly 5.

[0081] In some other embodiments of the present invention, the detection device 6 includes a first detection unit and a second detection unit.

[0082] The first detection unit is configured to generate a start signal to activate the detergent dispensing device 4 when the duration of a signal indicating that the laundry 10 is approaching exceeds a set threshold.

[0083] The second detection unit is configured to generate a start signal to activate the water outlet component 5 when the duration of a signal indicating that the laundry 10 is approaching exceeds a set threshold.

[0084] The control unit is further configured to, if it is determined that the washing machine is currently in the main wash stage, send the start signal generated by the first detection unit to the detergent dispensing device 4 or send the start signal generated by the second detection unit to the water outlet assembly 5.

[0085] In detail, when the washing machine is running and the user wants to continue adding water or detergent to the washing tub, it is obviously inconvenient to directly pour water into the washing tub or add detergent directly to the detergent dispenser. It may also cause water to spill outside the washing tub, resulting in overflow. The present invention can achieve the above purpose by using a detergent dispensing device 4 for cleaning local areas and a water inlet component.

[0086] When the control unit receives the start signal, it determines the current washing stage of the washing machine. If it is in the main wash stage, it can be assumed that the user triggered the detection device 6 to add extra water or detergent to the washing tub. At this time, the control unit sends a start signal to the detergent dispensing device 4 and / or the water outlet assembly 5.

[0087] It should be noted that the amount of detergent dispensed by the detergent dispensing device 4 upon activation can be preset in the washing machine's control unit, for example, 5ml of detergent per activation. Similarly, the amount of water dispensed by the water outlet assembly 5 upon activation can also be preset in the washing machine's control unit, for example, 1L of water per activation.

[0088] In addition, it is understood that the main washing stage mentioned above does not include the rinsing and dehydration stages.

[0089] Alternatively, the washing machine may also include a confirmation unit connected to the control unit. When the washing machine is detected to be in the main wash stage, confirmation information can be displayed on the confirmation unit of the washing machine to allow the user to confirm whether detergent or water has been sprayed. After the user confirms, a start signal for starting the detergent dispensing device 4 and / or the water dispensing assembly 5 is sent to the detergent dispensing device 4 and / or the water dispensing assembly 5.

[0090] Furthermore, during the user confirmation process, the amount of detergent or water to be sprayed can be displayed so that the user can set the amount. Once the user sets the amount of detergent or water to be sprayed, the detergent dispensing device 4 and the water dispensing component 5 will dispense the detergent according to the set amount.

[0091] It is understood that in the above implementation scheme, the detergent dispensing device 4 or the water outlet component 5 should be equipped with a dispensing volume controller, such as a flow meter or a metering pump.

[0092] Unlike the above embodiments, in some other embodiments of the present invention, only one detection unit is provided. After the detection device 6 detects the signal that the laundry 10 is approaching, it generates a start signal to start the detergent dispensing device 4 or the water outlet component 5. After a set delay time, it generates a start signal to start the detergent dispensing device 4.

[0093] Alternatively, after the detection device 6 detects a signal that the laundry 10 is approaching, it generates a start signal to activate the detergent dispensing device 4. After a set delay time, it generates a start signal to activate either the detergent dispensing device 4 or the water outlet assembly 5.

[0094] One cycle consists of adding detergent and water once. After this cycle is completed, if you need to add more detergent and water, you need to bring the clothes close to the detection device 6 again.

[0095] In the above solution, by setting a corresponding program in the control unit, a detection device 6 can simultaneously control the detergent dispensing device 4 and the water outlet assembly 5, which simplifies the user's operation and can also reduce the cost of the washing machine.

[0096] In some embodiments of the present invention, the detection device 6 is either an infrared sensing unit or a position sensor.

[0097] The infrared sensing unit and the position sensor can send a start signal by sensing the distance between the laundry 10 and the detection device 6.

[0098] In some embodiments of the present invention, the detergent dispensing device 4 is a foam-type detergent dispensing device 4.

[0099] In the above solution, the detergent dispenser 4 sprays out foam-type detergent, which makes the detergent foam finer and also eliminates the need for the user to rub and generate foam, saving time.

[0100] Specifically, the detergent dispensing device 4 includes a storage bottle, a dispensing pipe 41, and a foam generating device. The storage bottle is disposed inside the tray 2; the dispensing pipe 41 is disposed on the side wall of the clothing dispensing port 3, and the outlet of the dispensing pipe 41 extends out of the side wall of the tray 2 and is located inside the clothing dispensing port 3.

[0101] The foam generating device includes a gas-liquid mixing chamber, a liquid pump, a gas pump, and a drive mechanism. The gas-liquid mixing chamber is connected to the liquid outlet pipe 41; one end of the liquid pump is connected to the liquid storage bottle, and the other end is connected to the gas-liquid mixing chamber; one end of the gas pump is connected to the outside atmosphere, and the other end is connected to the gas-liquid mixing chamber; the drive mechanism is used to drive the liquid pump and the gas pump, and is configured to receive a signal to start the detergent dispensing device 4.

[0102] In some embodiments of the present invention, an opening is provided on the side wall of the clothing inlet 3, and the liquid outlet pipe 41 and the water outlet pipe of the water outlet assembly 5 are housed in the tray 2 or extend out of the side wall of the clothing inlet 3 through the opening.

[0103] Detailed, such as Figure 6As shown, when using the detergent dispensing device 4 and the water outlet assembly 5 to wash clothes, the liquid outlet pipe 41 and the water outlet pipe of the water outlet assembly 5 extend out of the side wall of the clothes dispensing port 3 through the opening and are exposed in the clothes dispensing port 3. When not in use, the liquid outlet pipe 41 and the water outlet pipe of the water outlet assembly 5 are stored in the tray 2 through the opening to avoid the liquid outlet pipe 41 and the water outlet pipe of the water outlet assembly 5 occupying the space of the clothes dispensing port 3.

[0104] In a further embodiment, the opening is provided with a pivotally connected cover. When the cover is closed, the outer wall of the cover forms the side wall of the clothing inlet 3. When the cover is open, the liquid outlet pipe 41 and the water outlet pipe of the water outlet assembly 5 extend out of the side wall of the clothing inlet 3 to spray detergent and water.

[0105] In the above solution, by setting a cover, when the opening is closed, the outer wall of the cover forms the side wall of the clothes loading port 3, thereby increasing the aesthetics of the washing machine.

[0106] In a further embodiment, the detergent dispensing device 4 and the water outlet assembly 5 are respectively equipped with an automatic telescopic mechanism that allows the liquid outlet pipe 41 and the water outlet pipe to automatically extend out of the side wall of the clothing dispensing port 3 through the opening.

[0107] The automatic telescopic mechanism is also connected to the detection device 6. When the signal of the laundry 10 approaching exceeds a set threshold for a duration exceeding the threshold, a start signal is generated to activate the automatic telescopic mechanism.

[0108] In summary, the control process of the washing machine of the present invention may include the following steps, such as... Figure 4 As shown:

[0109] S1, the detection device 6 detects a signal that the laundry 10 is approaching;

[0110] S2, determine whether the duration of the signal when the laundry 10 approaches exceeds the set threshold. If yes, proceed to step S3. If no, go into standby mode.
