Description

Technical Field

[0001] The present invention relates to the technical field of detergent dispensing, and particularly to an intelligent external detergent dispensing device for a washing machine. Background Art

[0002] With the evolution of smart home technology, the automatic detergent dispensing function of washing machines has been commercially applied. However, existing technical solutions still have functional limitations: mainstream products only achieve automatic dispensing after the start of the washing program, while the pre-filling of detergent before washing still requires manual operation, and a full-process automated closed-loop has not been formed.

[0003] Currently, although there are a few external dispensing devices on the market, their technical implementation mostly relies on peristaltic pumps or screw pumps to drive fluids. Moreover, such structures face significant challenges under low-temperature working conditions - when the environmental temperature decreases and the viscosity of the detergent increases, the pumping system is prone to feed delays or even pipeline blockages due to a sudden increase in fluid resistance.

Detailed implementation mode

[0019] In the description of the present application, the claims and the above-mentioned drawings, the terms "first", "second", etc. are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence. It should be understood that such terms can be interchanged under appropriate circumstances, and this is only a way of distinguishing when describing objects with the same attributes in the embodiments of the present application. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusion, so that a process, method, system, product or device including a series of units does not have to be limited to those units, but may include other units that are not clearly listed or are inherent to these processes, methods, products or devices.

[0020] Embodiment: Please refer to Figures 1 - 8 , in the embodiment of the present invention, an external detergent intelligent dispensing device for a washing machine is provided, including: A delivery rack 1, which is externally disposed on the upper part of the washing machine; A plurality of temporary storage assemblies 3 distributed in a circumferential array, each of the temporary storage assemblies 3 is embedded in the delivery rack 1, and the bottom of each of the temporary storage assemblies 3 is communicated with a blanking pipe 4; A plurality of material tanks 2, each of the material tanks 2 is correspondingly arranged for the temporary storage assembly 3, and is used to supply detergent to the temporary storage assembly 3; A spiral pipe 8, which is in a spiral descending shape and is sequentially connected to each of the blanking pipes 4, the upper end of the spiral pipe 8 is a closed end, and the lower end is connected to the mixing and oscillation assembly 9; The mixing and oscillation assembly 9 supplies detergent to the washing machine through a rubber pipe.

[0021] It should be explained that in the prior art, although some washing machines are equipped with an external detergent intelligent dispensing device, the application scenario of this detergent intelligent dispensing device is: automatic dispensing during the washing process; before washing, the operator still needs to manually put detergent into it, which is rather cumbersome. And this dispensing device can automatically put detergent into it instead of manual labor.

[0022] In this embodiment, since the dosing rack 1 is externally disposed on the upper part of the washing machine, therefore, there is no need to additionally configure a peristaltic pump, and the detergent can be dosed only by relying on gravity and hydraulic pressure.

[0023] In this embodiment, the spiral tube 8 is connected to each blanking tube 4 with the closed end at a high position and the open end at a low position. When the detergent descends along the spiral tube 8, the spiral structure generates a centrifugal effect and a path extension effect, so that different detergents are preliminarily mixed during the flow process.

[0024] Wherein, a first electromagnetic valve 5, a quantitative blanking assembly 6 and a second electromagnetic valve 7 are connected in series in the blanking tube 4 from top to bottom. By controlling the opening and closing of the first electromagnetic valve 5 and the second electromagnetic valve 7, the quantitative blanking assembly 6 can be assisted to perform quantitative blanking. Specifically, when the quantitative blanking assembly 6 quantitatively obtains the detergent, the first electromagnetic valve 5 is opened and the second electromagnetic valve 7 is closed; then when the quantitative blanking assembly 6 doses the quantitative detergent, the first electromagnetic valve 5 is closed and the second electromagnetic valve 7 is opened.

[0025] Through the alternating opening and closing of the first electromagnetic valve 5 and the second electromagnetic valve 7, the quantitative blanking assembly 6 is always in a physically isolated environment during the working cycle, avoiding the influence of continuous feeding of the upstream material tank 2 or pressure fluctuation of the downstream spiral tube 8 on the metering accuracy during the dosing process.

[0026] In this embodiment, the quantitative blanking assembly 6 includes: A quantitative tank 61, which is connected in series in the blanking tube 4; A rotating shaft, which is rotatably arranged in the quantitative tank 61 and is driven by an external stepping motor; Four quantitative plates 62 distributed in a circumferential array, one end of each quantitative plate 62 is fixed to the rotating shaft, and the other end contacts the inner wall of the quantitative tank 61.

[0027] During implementation, the first electromagnetic valve 5 is opened and the second electromagnetic valve 7 is closed, and the detergent flows from the temporary storage assembly 3 into the quantitative tank 61. The adjacent two of the four quantitative plates 62 and the inner wall of the quantitative tank 61 enclose a fan-shaped quantitative cavity, which is completely filled under the action of gravity and upstream pressure. Then, the first electromagnetic valve 5 is closed to isolate the upstream material tank 2, and the filled fan-shaped quantitative cavity becomes an independent metering unit, and its volume is accurately defined by the distance between the quantitative plates 62 and the inner diameter of the quantitative tank 61. Finally, the external stepping motor drives the rotating shaft to rotate, driving the quantitative plates 62 to rotate synchronously, so that the fan-shaped quantitative cavity loaded with detergent is transferred to the lower outlet end of the blanking tube 4. The second electromagnetic valve 7 is opened, and the detergent in the fan-shaped quantitative cavity is discharged through the blanking tube 4 under the action of gravity, completing a single quantitative dosing.

[0028] In this embodiment, a plurality of material tanks 2 are sequentially defined as the first material tank, the second material tank, the third material tank... the nth material tank; The storage tank 2 closest to the closed end of the spiral tube 8 is the first storage tank, and the first storage tank contains a diluent.

[0029] Further, the number of the storage tanks 2 is 7. Starting from the second storage tank, grapefruit detergent, mint detergent, cinnamon detergent, vanilla detergent, bergamot detergent, and cedar detergent are successively contained.

[0030] The first storage tank is adjacent to the closed end of the spiral tube 8. Its low-viscosity characteristic enables the diluent to enter the spiral tube 8 under the action of gravity, forming an initial liquid flow. When other detergents are injected into the spiral tube 8 through the subsequent feeding pipe 4, the diluent has occupied the wall surface of the spiral tube 8, forming a lubricating layer, reducing the adhesion of high-viscosity detergents.

[0031] Further, a controller is provided in the placing rack 1. The controller is used to control the first solenoid valve 5, the quantitative feeding assembly 6, and the second solenoid valve 7 according to user selection and temperature to adjust the detergent formula; For example, according to user selection, release mint detergent and grapefruit detergent to counteract the drowsiness in a high-temperature environment through a refreshing fragrance.

[0032] For example, according to user selection, release cinnamon detergent and vanilla detergent to make up for the decrease in olfactory sensitivity at low temperatures through a strong fragrance. And when the temperature is low, the release of the diluent can be increased to improve the influence of low temperature on the viscosity of the detergent.

[0033] For example, according to user selection, release bergamot detergent, cedar detergent, and diluent to adapt to daily use scenarios.

[0034] In this embodiment, a threaded rod 10 is fixed to the bottom of the mixing and oscillating assembly 9. A gasket 11 is sleeved on the threaded rod 10 and a knob 12 is threadedly connected to the threaded rod 10.

[0035] When installing this device, an installation hole needs to be opened in the cabinet above the washing machine so that the threaded rod 10 can pass through it. After that, a gasket 11 is sleeved on the threaded rod 10 and a knob 12 is threadedly connected to the threaded rod 10. The device is fastened by rotating the knob 12.

[0036] In this embodiment, the mixing and oscillating assembly 9 includes: A mixing chamber 91, in which a shaft body is rotatably arranged; A plurality of baffle plates 94 that are circumferentially distributed and fixed to the shaft body. The baffle plates 94 are arc-shaped, and a baffle ball 95 is fixed to the free end of the baffle plates 94; A sealed tube 92, which is communicated with one side of the mixing chamber 91, and a sliding tube 93 is slidably arranged in the sealed tube 92; The oscillating rod 96 has an arc-shaped structure at one end, and the other end is connected to the magnetic attraction member 97 through a micro-frame. The magnetic attraction member 97 is embedded in the sliding tube 93; Wherein, accommodation annular grooves are formed on the outer wall of the sliding tube 93 and the inner wall of the sealing tube 92 for jointly accommodating the annular elastic member 99; The sliding tube 93 supplies detergent to the washing machine through a rubber tube.

[0037] During implementation, an external power source (such as the motor 13) drives the shaft body in the mixing chamber 91 to rotate counterclockwise, driving the arc-shaped baffle 94 fixed on the shaft body to rotate synchronously. During the rotation of the baffle 94, the arc-shaped outer edge thereof periodically contacts the arc-shaped end of the oscillating rod 96. Due to the matching of their curvatures, jamming caused by rigid collision is avoided. The radial force applied by the baffle 94 pushes the oscillating rod 96 to slide inside the sealing tube 92, compressing the annular elastic member 99 (such as a spring) in the accommodation annular groove, and at the same time, the magnetic attraction member 97 is displaced synchronously inside the sliding tube 93. When the baffle 94 disengages, the elastic member 99 releases elastic potential energy, pushing the oscillating rod 96 to reset, and the magnetic attraction member 97 rebounds with the sliding tube 93 to the initial position. During this process, the rubber tube will be shaken to ensure that the detergent can fully flow into the washing machine.

[0038] It should be noted that by setting the mixing and oscillation assembly 9, the pre-mixing effect can also be improved, ensuring the subsequent flow effect, especially in the case of releasing the diluent. The low-viscosity characteristic of the diluent is coupled with the vibration flow field, significantly shortening the dissolution time of the high-viscosity detergent, especially in the low-temperature mode, and avoiding slow feeding caused by increased viscosity.

[0039] Furthermore, an electromagnetic ring 98 is also embedded in the sealing tube 92 for magnetically positioning the magnetic attraction member 97 so that the oscillating rod 96 is accommodated in the sealing tube 92.

[0040] When the electromagnetic ring 98 is powered on, a magnetic field is generated to adsorb the magnetic attraction member 97, driving the oscillating rod 96 to completely contract into the sealing tube 92 and lock. At this time, the elastic member 99 is compressed. The arc-shaped end of the oscillating rod 96 is flush with the end face of the sealing tube 92, and an unobstructed flow channel is formed in the mixing chamber 91. When the shaft body rotates clockwise, the arc-shaped outer edge of the baffle 94 contacts the fluid at a cutting angle opposite to the counterclockwise mode, improving the mixing effect.

[0041] In this embodiment, the temporary storage assembly 3 includes a temporary storage base 31. A positioning groove 32 and a temporary storage groove 33 are sequentially formed in the temporary storage base 31 from top to bottom. Wherein, the positioning groove 32 is used for positioning the material tank 2, the diameter of the temporary storage groove 33 is smaller than that of the positioning groove 32, the bottom of the temporary storage groove 33 penetrates the temporary storage base 31, and a thimble 34 is also fixed in the temporary storage base 31.

[0042] By setting the ejector pin, the sealing film at the opening of the material tank 2 can be punctured to ensure the smooth supply of the detergent.

[0043] In this embodiment, the placement rack 1 includes a support column 106. The top of the support column 106 is connected to an upper ring plate 101 through an upper connecting seat 103, and the bottom is connected to a lower ring plate 104 through a lower connecting seat 105. Among them, the lower ring plate 104 is used to carry the temporary storage assembly 3, and a centering hole 102 corresponding to the material tank 2 is opened on the upper ring plate 101. A motor 13 for providing power to the mixing and oscillating assembly 9 is fixed to the bottom of the lower connecting seat 105.

[0044] The support column 106 serves as a longitudinal support member, and the upper ring plate 101 and the lower ring plate 104 are respectively connected through the upper connecting seat 103 and the lower connecting seat 105 to form a rigid frame.

[0045] Preferably, the centering hole 102 of the upper ring plate 101 adopts a conical guiding design. After the bottom of the material tank 2 is inserted into the centering hole 102, circumferential positioning is achieved to ensure the axial alignment of the feeding pipe 4 and the temporary storage assembly 3.

[0046] The above-mentioned is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
