Description

Technical Field

[0001] This utility model belongs to the field of laundry cup technology, and in particular relates to a noise-reducing laundry cup. Background Technology

[0002] Because existing washing machines are prone to mold growth due to reasons such as difficulty in draining residual water and insufficient gap between the spin-drying tub and the washing tub, people with hygiene concerns are forced to switch to using laundry cups to wash underwear and other intimate clothing in order to ensure the cleanliness of these garments.

[0003] Chinese patent application No. 202410637600.2 discloses a novel laundry cup, including a base and a cup body disposed above the base. The upper top surface of the base is provided with an inner rim and an outer rim disposed outside the inner rim. A release box is provided between the inner rim and the outer rim. The release box has a contact surface that contacts the inner rim on its inner side. A feed inlet is provided on the contact surface. The release box has a release cavity extending from the feed inlet into its interior.

[0004] In the above technical solution, the cup body is used to hold and wash underwear and other intimate clothing by rotating relatively. However, in the above technical solution, the cup body needs to be driven to rotate relatively by a drive shaft. During the operation, due to the unavoidable assembly gap in the assembly of the drive shaft, the cup body generates noise, which stimulates the user's auditory nerves and affects the user's experience. Summary of the Invention

[0005] To address the shortcomings of existing technologies, a noise-reducing laundry cup is provided.

[0006] This utility model is achieved using the following technical solution:

[0007] A noise-reducing laundry cup includes a base with several cups for holding underwear and other intimate clothing. The base contains a drive mechanism with an output shaft extending to the outside of the base. The cups are poweredly connected to the output shaft. The base also has a noise-reducing mechanism that can wrap around the outside of the cups. The noise-reducing mechanism is a back plate that can block the propagation path of sound waves in one direction.

[0008] When the user needs to wash underwear and other intimate clothing, they place them in the cup and activate the drive mechanism. The drive mechanism causes the detergent and water in the cup to rotate the underwear and other intimate clothing inside the cup, thus cleaning the underwear and other intimate clothing. During this process, the noise generated by the cup is reduced by positioning the back panel in the path of sound waves propagating to the user.

[0009] Preferably, the base has a stepped portion that protrudes outward along the height direction of the cup body, and the back plate is disposed on the stepped portion and is positioned directly opposite the long side of the cup body, and the back plate extends upward along the axial direction of the cup body.

[0010] The backplate is designed to block the propagation path of sound waves generated by the cup during operation, thereby ensuring the noise isolation effect of the noise reduction mechanism.

[0011] Preferably, the back plate has an opening in the recessed groove that faces the cup body, and the back plate wraps around the cup body from the outer circular surface of the cup body through the recessed groove.

[0012] The embedded slot allows the backplate to partially wrap around the outside of the cup, achieving negative distance embedded contact between the two and increasing the range of noise wave propagation blocked by the backplate, thereby improving the noise insulation effect.

[0013] Preferably, the wall of the embedding groove is in close contact with the outer circular surface of the cup body.

[0014] By eliminating the gap between the groove wall of the embedded groove and the outer circular surface of the cup, the back plate can support the cup and thus radially limit the cup, eliminating the swaying caused by the shaft transmission during operation, thereby reducing shaft vibration at the source and reducing the intensity of the vibration source.

[0015] Preferably, the back panel is hollow inside, thereby utilizing the air inside the back panel to absorb and attenuate sound wave energy, block vibration transmission, and improve noise isolation effect.

[0016] Preferably, a countersunk groove is provided on the stepped portion opposite the position of the cup body, and the outlet shaft extends into the countersunk groove for connection to the bottom of the cup body.

[0017] The countersunk groove is designed for assembling the cup body and the stepped part. The cup body and the countersunk groove can be connected and fixed by any existing snap-fit ​​method.

[0018] Preferably, the countersunk groove has an upward-facing overflow hole, and the base has an independent drainage channel that is connected to the overflow hole.

[0019] By setting an overflow hole in the countersunk sink, water that seeps out of the washing cup can be discharged through a set drainage channel, preventing water from accumulating in the countersunk sink and forming a dead corner for hygiene after drying, or further seeping into the base and causing a short circuit in the drive mechanism.

[0020] Preferably, a cover plate is sealed at the mouth of the cup body, and a placement chamber for holding underwear and other intimate clothing is formed between the cover plate and the cup body. A drive disc that can rotate relative to the cup body is provided on the lower side of the placement chamber, and the drive disc can agitate the detergent and water in the placement chamber.

[0021] The drive mechanism drives the drive disc to rotate, which agitates the detergent and water in the placement chamber, and causes underwear and other intimate clothing to rotate with the mixture of detergent and water to complete the washing process.

[0022] Preferably, the outer circular surface of the cup body is provided with a concave strip, which protrudes into the inner side of the placement cavity and forms a ridge for rubbing against underwear and other close-fitting clothing.

[0023] By using the set ribs, when underwear and other intimate clothing rotate with the mixed liquid, they are squeezed and rubbed against each other by centrifugal force as they pass through the ribs. This creates a micro-fluid pump-like structure at the point of contact, which squeezes out the sewage carried by the underwear and other intimate clothing, thereby completing the cleaning process.

[0024] Preferably, the inner wall of the cup is made of a material containing silver ions, and the cup is equipped with a light-irradiating structure that can irradiate light with sterilization function, thereby improving the sterilization effect on underwear and other intimate clothing.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] By covering the outside of the cup body with a back plate to block the sound wave propagation path, a physical barrier is formed on one side of the cup body to isolate the noise generated by the cup body during operation. By ensuring that the back plate is in close contact with the cup body, the shaft oscillation caused by the output shaft transmission of the cup body is eliminated, thereby suppressing the generation of noise from the vibration source and reducing the noise generated when the cup body is working. This achieves synergy between vibration source suppression and propagation blocking, improving the noise isolation effect of the device. Attached Figure Description

[0033] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0034] like Figure 1 As shown, this embodiment discloses a noise-reducing laundry cup, including a base 10, on which three cups 15 for holding underwear and other intimate clothing are arranged in an array along their length. Figure 3 As shown, the base 10 is provided with a stepped portion 12 that protrudes outward along the axial direction of the cup body 15. A countersunk groove 13 is provided on the stepped portion 12 at the position opposite to the cup body 15. The side wall of the countersunk groove 13 and the bottom of the cup body 15 are connected by any existing snap-fit ​​structure to fix the cup body 15 relatively.

[0035] like Figure 4 , Figure 5 As shown, a cover plate 16 is sealed to the mouth of the cup body 15 by a sealing ring 17. The cover plate 16 and the mouth of the cup body 15 are connected by any existing snap-fit ​​structure to fix the cover plate 16 axially and circumferentially. A base plate 18 is sealed to the bottom of the cup body 15. The base plate 18, the cover plate 16 and the cup body 15 together form a storage chamber for holding underwear and other intimate clothing. The lower part of the storage chamber is provided with a rotatable part relative to the cup body 15 and the base plate 18. The drive disc 19 has a first agitator 20, a second agitator 21 and a receiving hole 22 arranged at intervals. The first agitator 20 and the second agitator 21 protrude upward along the axial direction of the cup body 15. The receiving hole 22 is a blind hole with an upward opening. When the drive disc 19 rotates, it can agitate the detergent and water in the placement chamber through the first agitator 20, the second agitator 21 and the receiving hole 22, thereby driving underwear and other intimate clothing to rotate to complete the washing.

[0036] The outer circular surface of the cup body 15 is provided with a concave strip 23, which protrudes into the inner side of the placement cavity and forms a ridge 24 for rubbing against underwear and other close-fitting clothing.

[0037] like Figure 3As shown, a drive mechanism 25 is provided in the base 10. The output shaft 26 of the drive mechanism 25 extends into the countersunk groove 13. The output shaft 26 of the drive mechanism 25 passes through the bottom of the cup body 15 and is connected to the drive disk 19 by a spline key. The spline key is the same as the existing structure. The bottom of the cup body 15 and the outer circular surface of the output shaft 26 are rotated and supported by any existing sealing element that can achieve dynamic sealing.

[0038] To prevent water seeping from the cup body 15 from entering the inner side of the drive mechanism 25, an overflow hole 14 with an upward opening is provided in the countersunk groove 13, and a drainage channel connected to the overflow hole 14 is provided in the base 10. The drainage channel is set independently, thereby preventing the seeping water from interfering with the drive mechanism 25. The drainage channel can be any existing drainage structure, such as a drain pipe or a cavity opened in the inner wall of the base 10.

[0039] To ensure the sterilization effect after washing underwear and other intimate clothing, the inner wall of the cup body 15 is made of a material containing silver ions, and the cup body 15 is equipped with a light-irradiation structure that can irradiate light with sterilization function. The light-irradiation structure is the same as the existing technology structure.

[0040] like Figure 2 As shown, the noise reduction mechanism 11 includes a back plate 30. The back plate 30 is formed by the step portion 12 extending upward along the axial direction of the cup body 15, which is opposite to the long side of the cup body 15. The back plate 30 is hollow inside. The connecting root 31 between the back plate 30 and the step portion 12 extends beyond the cup body 15 at a diameter position parallel to the length direction of the base 10, thereby forming a mountain-shaped semi-enclosed structure close to the cup body 15. An embedding groove 32 with an opening facing the cup body 15 is provided in the back plate 30. The back plate 30 wraps around the cup body 15 from the outer circular surface of the cup body 15 through the embedding groove 32. The groove wall of the embedding groove 32 is in close contact with the outer circular surface of the cup body 15.

[0041] When a user washes underwear and other intimate apparel, the underwear and other intimate apparel are placed in the placement chamber inside the cup body 15. The drive mechanism 25 is then activated. The drive mechanism 25 drives the drive disc 19 to rotate via the output shaft 26. This causes the detergent and water inside the cup body 15 to rotate the underwear and other intimate apparel within the cup body 15. The underwear and other intimate apparel then come into contact with and rub against the first agitator bar 20, the second agitator bar 21, the rib 24, and the receiving hole 22, thereby cleaning the underwear and other intimate apparel. During this process, the back plate 30 forms a physical barrier on one side of the cup body 15 that can isolate the noise generated by the operation of the cup body 15 and eliminate the shaft oscillation caused by the transmission of the output shaft 26. This achieves the mutual synergy of vibration source suppression and propagation blocking, thereby improving the noise isolation effect.
