Description

Technical Field

[0001] This invention belongs to the field of cleaning equipment technology, and more specifically, relates to a washing machine. 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 washing to 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 has a liquid outlet only on the side wall of the clothes inlet, while the detergent dispensing device and the water outlet assembly are all located inside the tray. This makes the washing machine more aesthetically pleasing and the overall structure more compact when achieving the purpose of local cleaning.

[0009] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0017] The linkage control unit is connected to the switching unit and the detection device respectively. It is configured to control the first inlet to connect with the outlet when it receives the start signal to start the washing dispensing device, and to control the second inlet to connect with the outlet when it receives the start signal to start the water outlet component.

[0018] Furthermore, the detergent dispensing device is a foam-type detergent dispensing device.

[0019] Furthermore, the detergent dispensing device includes:

[0020] A liquid storage bottle is disposed within the tray base;

[0026] Furthermore, the water outlet assembly includes:

[0027] The water outlet pipe is installed inside the tray base, with one end connected to the water inlet valve of the washing machine and the other end connected to the second inlet.

[0028] A solenoid valve, installed on the water outlet pipe, is configured to receive signals to start / stop the water outlet assembly and control the opening and closing of the water outlet pipe.

[0029] Furthermore, the detection device sequentially generates activation signals to start the water outlet component or the detergent dispensing device as the number of detections increases.

[0030] Furthermore, the detection device includes:

[0031] The first detection unit is configured to generate a start signal to activate the detergent dispensing device when a signal indicating that the laundry is approaching is detected, and to generate a shut-off signal to deactivate the detergent dispensing device when no signal indicating that the laundry is approaching is detected.

[0032] The second detection unit is configured to generate a start signal to activate the water outlet component when a signal indicating that the laundry is approaching is detected, and to generate a stop signal to deactivate the water outlet component when no signal indicating that the laundry is approaching is detected.

[0054] 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

[0055] 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.

[0056] 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.

[0057] 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.

[0058] like Figures 1 to 6 As shown, the present invention provides a washing machine, including a housing 1, a tub assembly inside the housing 1, and a tray base 2 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. A liquid outlet 4 is provided on the side wall of the clothes inlet 3, and the tray base 2 is also provided with a cover 9 for opening and closing the clothes inlet 3.

[0059] The washing machine also includes a detergent dispensing device, a water outlet assembly, and a switching unit. The detergent dispensing device is located inside the tray 2 and is used to supply detergent to the liquid outlet 4. The water inlet assembly is located inside the tray 2 and is used to supply water to the liquid outlet 4.

[0060] The switching unit has a first inlet, a second inlet, and an outlet. The first inlet and the second inlet are respectively connected to the detergent dispensing device and the water outlet assembly. The outlet is connected to the liquid outlet 4. The switching unit is configured to connect to the outlet by selecting one of the first inlet and the second inlet.

[0061] As can be seen, the detergent dispensing device and water outlet assembly described above are different from the detergent dispensing device and water inlet assembly installed on conventional washing machines for dispensing detergent into the drum assembly. Instead, they provide water or detergent to the clothes inlet 3 through the liquid outlet 4, so that users can clean the more soiled areas on the clothes 10 to be washed.

[0062] In detail, during use, when it is necessary to wet the clothes, connect the second inlet and outlet of the switching unit. At this time, water flows out from outlet 4 to wet the clothes. When it is necessary to apply detergent, connect the first inlet and outlet of the switching unit. At this time, detergent flows out from outlet 4 to clean stains on the clothes.

[0063] In the above solution, only one liquid outlet 4 is provided on the side wall of the clothes inlet 3, while the detergent dispensing device and water outlet components are all located inside the tray 2, making the washing machine more aesthetically pleasing and the overall structure more compact.

[0064] In a further embodiment, the washing machine also includes a detection device 6 and a linkage control unit. The detection device 6 is configured to generate a start signal to activate the detergent dispensing device or the water outlet assembly upon detecting a signal indicating that the laundry 10 is approaching, and to generate a stop signal to deactivate the detergent dispensing device or the water outlet assembly upon not detecting a signal indicating that the laundry 10 is approaching. The linkage control unit is connected to both the switching unit and the detection device 6, and is configured to connect the first inlet to the outlet upon receiving a start signal to activate the detergent dispensing device, and to connect the second inlet to the outlet upon receiving a start signal to activate the water outlet assembly.

[0065] It is evident that the detergent dispensing device and water outlet assembly are not controlled by the washing machine's preset washing program, but rather by the detection device 6.

[0066] The above solution provides detergent dispensing devices and water outlet components for supplying detergent and water respectively in the tray base 2, and the detection device 6 controls whether they are activated. During the local cleaning process, the process of wetting clothes and adding detergent can be carried out alternately, which improves the cleaning effect on local areas.

[0067] In addition, the linkage control unit can control the switching unit's path according to the signal generated by the detection device 6, so as to automatically control the flow of water or detergent from the outlet 4, improve the automation level of local cleaning, simplify user operation steps, and improve user experience.

[0068] In some embodiments of the present invention, the detergent dispensing device is a foam-type detergent dispensing device.

[0069] In the above solution, the detergent dispenser provides foam-type detergent, which makes the detergent foam finer and also eliminates the need for the user to rub the detergent to generate foam, saving time.

[0070] Specifically, the detergent dispensing device includes a liquid storage bottle and a foam generator, with the liquid storage bottle disposed within the tray 2.

[0071] The foam generator 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 first inlet pipe of the switching unit; 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.

[0072] In some embodiments of the present invention, the water outlet assembly includes a water outlet pipe and a solenoid valve.

[0073] The water outlet pipe is installed inside the tray 2, with one end connected to the water inlet valve of the washing machine and the other end connected to the second inlet.

[0074] The solenoid valve is installed on the water outlet pipe and is configured to receive signals to start / stop the water outlet assembly to control the opening and closing of the water outlet pipe.

[0075] In some embodiments of the present invention, the detection device 6 generates activation signals to start the water outlet component or the detergent dispensing device in alternating order with the number of detections.

[0076] The detection device 6 sequentially generates a start signal to activate the water outlet component, a stop signal to deactivate the water outlet component, a start signal to activate the detergent dispensing device, and a stop signal to deactivate the detergent dispensing device.

[0077] In detail, during use, such as Figure 2As shown, when the detection device 6 detects the approach of the garment 10 to be washed, it generates a start signal to activate the water outlet assembly and sends the start signal to the solenoid valve and the linkage control unit. Upon receiving the start signal, the solenoid valve controls the water outlet pipe to open. Upon receiving the start signal, the linkage control unit controls the second inlet and outlet of the switching unit to connect. Water then flows out from the outlet 4 and sprays onto the garment inlet 3, wetting the garment 10. When the user determines that the garment is thoroughly wet, they remove the garment from the detection range of the detection device 6. When the detection device 6 no longer detects the approach of the garment, it generates a shut-off signal to close the water outlet assembly and sends the shut-off signal to the solenoid valve. Upon receiving the shut-off signal, the solenoid valve controls the water outlet pipe to disconnect, stopping the spraying of water onto the garment inlet 3. Figure 1 As shown, when the detection device 6 detects the laundry 10 approaching again, it generates a start signal to activate the detergent dispensing device and sends the start signal to the drive mechanism and the linkage control unit. Upon receiving the start signal, the drive mechanism converts the detergent from a liquid state to a foam state. Simultaneously, the linkage control unit connects the first inlet of the switching unit to the outlet. At this point, the foam-type detergent is sprayed from the liquid outlet 4 into the laundry dispensing port 3, applying it to the laundry 10. When the user determines that an appropriate amount of detergent has been sprayed, they move the laundry out of the detection range of the detection device 6. When the detection device 6 no longer detects the laundry approaching, it generates a shut-off signal to close the detergent dispensing device and sends the shut-off signal to the drive mechanism. Upon receiving the shut-off signal, the drive mechanism stops generating foam-type detergent.

[0078] Thus, as Figure 3 As shown, the garment 10 to be washed is wetted and coated with detergent. After the user rubs the garment 10 and visually assesses that the stains have been removed, the user brings the garment 10 close to the detection device 6 again. When the detection device 6 detects the garment 10 approaching, it generates a start signal to activate the water outlet assembly and sends the start signal to the solenoid valve and the linkage control unit. Upon receiving the start signal, the solenoid valve controls the water outlet pipe to open. Upon receiving the start signal, the linkage control unit controls the second inlet and outlet of the switching unit to connect. At this time, water flows out from the liquid outlet 4 and sprays water onto the garment inlet 3, rinsing the detergent foam off the garment 10.

[0079] After the detergent foam is rinsed off, the user visually inspects whether the stains on the laundry 10 have been cleaned. If clean, the user moves the laundry out of the detection range of the detection device 6. Once the detection device 6 no longer detects the laundry approaching, it generates a shut-off signal to close the water outlet assembly and sends this signal to the solenoid valve. Upon receiving the shut-off signal, the solenoid valve disconnects the water outlet, stopping the spraying of water to the laundry inlet 3. The user then places the laundry 10 into the tub assembly. If the laundry is still not clean, the user can bring the laundry close to the detection device 6 again. When the detection device 6 detects the laundry 10 approaching again, it generates a start signal to activate the detergent dispensing device and sends this signal to the drive mechanism and the linkage control unit. Upon receiving the start signal, the drive mechanism converts the detergent from a liquid state to a foam state. Simultaneously, the linkage control unit connects the first inlet of the switching unit to the outlet, allowing the foam-type detergent to be sprayed from the liquid outlet 4 into the laundry inlet 3. When the user determines that an appropriate amount of detergent has been sprayed, the user moves the clothes away from the detection range of the detection device 6. After the detection device 6 no longer detects the signal of the clothes approaching, it generates a shutdown signal to turn off the detergent dispensing device and sends the shutdown signal to the drive mechanism. After receiving the shutdown signal, the drive mechanism stops spraying detergent into the clothes dispensing port 3.

[0080] Users can control the number of cycles of wetting clothes and applying detergent based on the actual washing results. If a localized area of ​​the garment 10 is only lightly soiled, one or two cycles are sufficient to achieve the desired washing effect. If a localized area of ​​the garment 10 is heavily soiled, three or four cycles are sufficient to achieve the desired washing effect.

[0081] In the above solution, the user can control whether the clothes are close to the detection device 6 according to the actual situation, so that the spray water and the spray detergent alternate, improving the cleaning effect on local areas. Moreover, only one detection device 6 is needed to control the water output component and the detergent dispensing device, reducing the number of washing machine parts, simplifying the assembly relationship, and saving equipment costs.

[0082] In terms of placement, the detection device 6 can be placed near the liquid outlet 4, for example, around the liquid outlet 4.

[0083] In some embodiments of the present invention, such as Figure 6 As shown, the detection device 6 includes a first detection unit 61 and a second detection unit 62.

[0084] The first detection unit 61 is configured to generate a start signal to start the detergent dispensing device when a signal is detected that the laundry 10 is approaching, and to generate a shut-off signal to shut off the detergent dispensing device when no signal is detected that the laundry 10 is approaching.

[0085] The second detection unit 62 is configured to generate a start signal to activate the water outlet component when a signal is detected that the laundry 10 is approaching, and to generate a stop signal to deactivate the water outlet component when no signal is detected that the laundry 10 is approaching.

[0086] In detail, during use, when the second detection unit 62 detects the approach of the garment 10 to be washed, it generates a start signal to activate the water outlet assembly and sends the start signal to the solenoid valve and the linkage control unit. After receiving the start signal, the solenoid valve controls the water outlet pipe to open, and after receiving the start signal, the linkage control unit controls the second inlet and outlet of the switching unit to connect. At this point, water flows out from the liquid outlet 4 and sprays water onto the garment inlet 3 to wet the garment 10. When the user determines that the garment is thoroughly wet, they move the garment out of the detection range of the second detection unit 62. After the second detection unit 62 no longer detects the signal of the garment approaching, it generates a shut-off signal to close the water outlet assembly and sends the shut-off signal to the solenoid valve. After receiving the shut-off signal, the solenoid valve controls the water outlet pipe to disconnect, stopping the spraying of water onto the garment inlet 3. When the first detection unit 61 detects the approach of the garment 10 to be washed, it generates a start signal to activate the detergent dispensing device and sends the start signal to the drive mechanism and the linkage control unit. Upon receiving the start signal, the drive mechanism converts the detergent from a liquid state to a foam state. Simultaneously, the linkage control unit connects the first inlet of the switching unit to the outlet. At this point, the foam-type detergent is sprayed through the liquid outlet 4 into the garment dispensing port 3 and applied to the garment 10. When the user determines that an appropriate amount of detergent has been sprayed, the garment is moved out of the detection range of the first detection unit 61. When the first detection unit 61 no longer detects the approach of the garment, it generates a shut-off signal to deactivate the detergent dispensing device and sends the shut-off signal to the drive mechanism. Upon receiving the shut-off signal, the drive mechanism stops spraying detergent into the garment dispensing port 3.

[0087] At this point, the garment 10 is wetted and coated with detergent. After the user rubs the garment 10 and visually assesses that the stains have been removed, the user brings the garment 10 closer to the second detection unit 62. When the second detection unit 62 detects the garment 10 approaching, it generates a start signal to activate the water outlet assembly and sends the signal to the solenoid valve and the linkage control unit. Upon receiving the start signal, the solenoid valve controls the water outlet pipe to open. Upon receiving the start signal, the linkage control unit controls the second inlet and outlet of the switching unit to connect. Water then flows out from the liquid outlet 4 and sprays onto the garment inlet 3, rinsing the detergent foam off the garment 10.

[0088] After the detergent foam is rinsed off, the user visually inspects whether the stains on the laundry 10 have been cleaned. If clean, the user moves the laundry out of the detection range of the second detection unit 62. The second detection unit 62, no longer detecting the laundry's proximity, generates a shut-off signal to close the water outlet assembly and sends this signal to the solenoid valve. Upon receiving the shut-off signal, the solenoid valve stops spraying water into the laundry inlet 3, and the user places the laundry 10 into the tub assembly. If the laundry is still not clean, the user can bring the laundry closer to the first detection unit 61. When the first detection unit 61 detects the laundry 10 approaching, it generates a start signal to activate the detergent dispensing device and sends this signal to the drive mechanism and the linkage control unit. Upon receiving the start signal, the drive mechanism converts the detergent from liquid to foam. Simultaneously, the linkage control unit connects the first inlet of the switching unit to the outlet. Thus, the foam-type detergent is sprayed from the outlet 4 into the laundry inlet 3 and applied to the laundry 10. When the user determines that an appropriate amount of detergent has been sprayed, the user moves the clothes away from the detection range of the first detection unit 61. After the first detection unit 61 no longer detects the signal of the clothes approaching, it generates a shutdown signal to turn off the detergent dispensing device and sends the shutdown signal to the drive mechanism. After receiving the shutdown signal, the drive mechanism stops spraying detergent into the clothes dispensing port 3.

[0089] Users can control whether the clothes are close to the first detection unit 61 and the second detection unit 62 according to the actual situation, so that the spraying of water and the spraying of detergent alternate, thereby improving the cleaning effect on local areas.

[0090] In the above solution, two detection units are set up to control the water outlet component and the detergent dispensing device separately, which improves the flexibility of control over the water outlet component and the detergent dispensing device, better meets the user's usage habits, and improves the user experience.

[0091] In terms of positioning, the first detection unit 61 and the second detection unit 62 can be respectively located on both sides of the liquid outlet 4.

[0092] In some embodiments of the present invention, the detection device 6 can be any one of an infrared sensing unit, a voice recognition module, or a position sensor.

[0093] The infrared sensing unit and the position sensor can send a start or stop signal by sensing the distance between the laundry 10 and the detection device 6.

[0094] The voice recognition module can send start or stop signals by recognizing voice control commands such as "start detergent", "stop detergent", "start water flow", and "stop water flow".

[0095] In some embodiments of the present invention, the washing machine further includes a control panel 7, which is provided with a program selector and additional function selection buttons, etc. The control panel 7 is disposed on the tray base 2. In particular, the control panel 7 provided by the present invention is provided with control buttons 8, which are configured to control whether the detection device 6 generates a start signal to start the detergent dispensing device or the water outlet assembly.

[0096] Detailed, such as Figure 4 As shown, since the detection device 6 is set on the tray base 2, the user will inevitably pass through the detection device 6 when putting clothes into the tub assembly. In order to avoid the detection device 6 being accidentally triggered, the present invention sets a control button 8 on the control panel 7. Only when the control button 8 is in the selected state will the detection device 6 detect whether there is a garment 10 to be washed approaching. Otherwise, the detection device 6 will not detect whether there is a garment 10 to be washed approaching.

[0097] 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 and detergent dispensing device, and reduces the possibility of being triggered erroneously.

[0098] In some embodiments of the present invention, an opening is provided on the side wall of the clothing inlet 3, and the liquid outlet 4 is connected to a liquid outlet pipe 5, which is received in the tray 2 or extends out of the side wall of the clothing inlet 3 through the opening along with the liquid outlet pipe 5.

[0099] Detailed, such as Figure 5 As shown, when using the detergent dispensing device and water outlet assembly to wash clothes, the liquid outlet pipe 5 and the liquid outlet 4 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 5 and the liquid outlet 4 are stored in the tray 2 through the opening to avoid the liquid outlet pipe 5 and the liquid outlet 4 occupying the space of the clothes dispensing port 3.

[0100] 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 5 and the liquid outlet 4 extend out of the side wall of the clothing inlet 3 to spray detergent and water.

[0101] 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.

[0102] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
