Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and embodiments, it being understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

Referring to fig. 1, 2, 4 and 5, the invention provides a detergent dissolving box for a washing machine, which comprises a shell 1 fixedly installed in the washing machine, wherein a placing bin 11 for containing detergent is arranged above the inside of the shell 1, and a channel 12 for water flow to pass through is arranged below the inside of the shell; a communicating bin 13 which can communicate the placing bin 11 and the channel 12 and is used for detergent to enter the channel 12 from the placing bin 11 is arranged between the placing bin 11 and the channel 12; a crushing mechanism for crushing hard particles when a detergent passes through the inside of the communicating bin 13 is arranged in the communicating bin; a water inlet 14 is arranged at one end of the placing bin 11, the water inlet 14 is communicated with the same water supply source through the channel 12, a timing valve (not shown in the figure) is arranged at the water inlet 14, after the timing valve is opened, outside water flows enter the placing bin 11, and then the timing valve is closed after a preset time (the preset time is 1/3 of the whole water injection process) is opened, so that the control of the water flow entering the placing bin 11 is realized;

referring to fig. 2 and 7, in order to facilitate the detergent to be placed in the placing chamber 11, a detergent containing box 6 is movably installed in the placing chamber 11, and the detergent containing box 6 has a cylindrical structure and comprises a first shell 61 and a second shell 62 which are inserted into each other. The first shell 61 is provided with a first through hole 611 for communicating with the bin 13, and one side end face of the second shell 62 is provided with a second through hole 621 communicated with the water inlet 14.

When the detergent containing box 6 is used, firstly, the detergent containing box 6 is taken out of the placing bin 11, the first shell 61 and the second shell 62 are disassembled, detergent is poured into the second shell 62, then the first shell 61 and the second shell 62 are combined in an inserting mode (at the moment, the first shell 61 is positioned at the upper end, the opening of the first through hole 611 faces upwards), the detergent containing box 6 is inserted into the placing bin 11 again, and finally the detergent containing box 6 is rotated by 180 degrees, so that the first through hole 611 is communicated with the communicating bin 13. In this example, the second housing 62 is provided with a protrusion 622 for positioning when the detergent containing box 6 rotates, so as to ensure that the first through hole 611 and the communicating chamber 13 can be accurately positioned.

Referring to fig. 2, a reduced section 51 is disposed in the middle of the channel 12, and the reduced section 51 makes the channel 12 at the left end thereof a large-caliber channel 121 and the right end thereof a small-caliber channel 122, wherein the communicating chamber 13 communicates with the small-caliber channel 122. Under the action of the necking section 51, a negative pressure is generated in the small-caliber passage 122 due to the increase of the flow speed of the water, and the negative pressure drives the detergent in the placing chamber 11 into the inside of the passage 12.

Referring to fig. 2 and 5, the crushing mechanism includes a fixed ring 31 fixedly installed at the upper end of the communicating bin 13, a rotating ring 33 coaxially located at the lower end of the fixed ring 31 and capable of switching between forward rotation and reverse rotation, a reciprocating rotating mechanism driving the rotating ring 33 to rotate, and a plurality of crushing lines 34 with certain elasticity annularly arranged between the rotating ring 33 and the fixed ring 31. A crushing space with a conical structure is formed among the plurality of crushing lines 34, and after the rotating ring 33 rotates, a preset position in the crushing space shrinks; after the rotating ring 33 is reversely rotated and reset, the crushing space is reset;

in this example, the device, in use:

the water pump of the washing machine is started (water flow starts to fill water into the washing tub through the channel 12), the timing valve is opened, the water flow enters the placing bin 11 from the water inlet 14, the water flow entering the placing bin 11 is initially mixed with the detergent, the timing valve is closed after the predetermined time (the predetermined time is 1/3 of the whole water filling process, the time control of the timing valve can be controlled by a PLC (programmable logic controller) control timer arranged in the washing machine, the PLC control timer is a technical means well known by a person skilled in the art), due to the existence of the negative pressure at the small-caliber channel 122, the negative pressure can drive the mixture of the detergent and the water to enter the channel 12 through the communicating bin 13 (explained, because the first shell 61 and the second shell 62 are in a splicing mode, the connecting mode enables a gap communicated with the outside to be formed at the connecting position, when the water flow of the placing bin 11 is sucked into the channel 12, outside air enters the placing chamber 11 so that negative pressure is not generated inside the placing chamber 11, and a vent hole may be opened at a predetermined position of the detergent containing box 6 if necessary).

Referring to fig. 5, 8 and 9, during the detergent passing through the communicating chamber 13, undissolved hard particles are blocked into the crushing space between the fixed ring 31 and the rotating ring 33. When the hard particles are crushed, the rotating ring 33 rotates relative to the fixed ring 31, and the rotating ring 33 rotates and drives the crushing line 34 to be twisted. This "twisting" occurs at a predetermined position between the fixed ring 31 and the rotating ring 33 (the setting at which can be changed by changing the relative diameter between the fixed ring 31 and the rotating ring 33), and the area surrounded by the plurality of crushing wires 34 is reduced in diameter, and the crushing wires 34 at the inner periphery in this area crush the hard particles.

The rotating ring 33 is driven by a reciprocating rotating mechanism to perform reciprocating forward and reverse rotation switching work so as to generate an effect of continuous extrusion, and the reciprocating rotating mechanism comprises a rotation driving gear ring 32 concentrically and fixedly connected with the rotating ring 33, an incomplete gear 35 matched with the rotation driving gear ring 32, a gear driving assembly driving the incomplete gear 35 to rotate and a torsion spring 100 driving the rotating ring 33 to reset.

The inner wall of the communication bin 13 is provided with a containing bin, the rotary driving gear ring 32 and the torsion spring 100 are arranged in the containing bin, one end of the torsion spring 100 is fixedly connected with the rotary driving gear ring 32, and the other end of the torsion spring is fixedly connected with the bin wall of the containing bin. The rotation driving ring gear 32 is connected to the rotation ring 33 by a link rod having a diameter as small as possible while securing the coupling strength thereof to reduce the resistance to the flow of water in which detergent is dissolved.

When the reciprocating rotation mechanism drives the rotation ring 33 to rotate, the incomplete gear 35 is driven by the gear driving assembly to rotate, specifically, the rotation driving gear ring 32 and the incomplete gear 35 are in gear mesh transmission, the rotation ring 33 is driven by the rotation driving gear ring 32 to rotate (at this time, the torsion spring 100 is compressed), and then, the rotation ring 33 drives the crushing line 34 to crush hard particles. When the meshing transmission enters the toothless region of the incomplete gear 35, the incomplete gear 35 cannot drive the rotation driving ring gear 32 to rotate, and then the rotation driving ring gear 32 drives the rotation ring 33 to return to the original state under the returning action of the torsion spring 100.

Referring to fig. 2, the gear driving assembly for driving the incomplete gear 35 to rotate includes a water flow fan 41 driven by water flow and generating a rotating force, and a water flow fan support 42 for supporting the water flow fan 41 (shown in fig. 3) and fixedly connected to the channel 12; the water flow fan 41 is rotatably mounted on the water flow fan support 42, a power gear ring 43 is fixedly connected to one end of the water flow fan 41, a gear structure 351 (shown in fig. 6) is arranged at one end of the incomplete gear 35, and the power gear ring 43 is meshed with the gear structure 351. When the incomplete gear 35 is driven to rotate, the water flow drives the water flow fan 41 to rotate directionally, and the water flow fan 41 rotates by driving the incomplete gear 35 to rotate directionally through the power gear ring 43. The gear drive assembly may also be driven by a conventional rotary motor. However, compared with the driving by a rotating motor, the gear driving assembly driven by water flow does not need an additional power source, so that the structure is compact while the power source is saved (the additional rotating motor inevitably increases the occupied space of the device).

When mixing is performed, the flow rate of the water flowing from the large-diameter passage 121 into the small-diameter passage 122 is changed due to the presence of the constricted section 51, and the flow rate of the water flowing into the small-diameter passage 122 is increased (negative pressure is generated in this place due to the increase in the flow rate of the water). The water flow with detergent flowing out of the placing chamber 11 collides with the water flow in the small-bore passage 122, so that the detergent is secondarily mixed with the water flow. Simultaneously, the negative pressure that produces in the minor-caliber passage 122 can produce suction, places the inflow of the rivers in storehouse 11 with higher speed, simultaneously, when the stereoplasm granule is carrying out the breakage, this suction can play fixed effect, when avoiding broken line 34 to compress tightly the breakage to the stereoplasm granule, the stereoplasm granule upwards pops out for broken mechanism can't normal operating.

Referring to fig. 2 and 5, a plurality of the communicating chambers 13 and the crushing mechanism (2 in the example shown in the figure) are distributed along the axial direction of the channel 12, and referring to fig. 6, two adjacent rotary driving ring gears 32 are connected through a gear shaft, and the gear shaft includes a connecting shaft 101 at the center and incomplete gears 35 at two ends thereof.

The crushing efficiency of the hard particles can be increased by arranging a plurality of crushing mechanisms.

Preferably, the rotary joints of the rotary driving gear ring 32 and the power gear ring 43 are provided with sealing structures, the sealing structures are arranged to prevent tiny detergent particles from entering the meshing positions between the gears, so that the operation of the device is affected, and the sealing structures adopt labyrinth seals (the sealing mode is a conventional technical means of a person skilled in the art), so that the sealing structures have the advantage of convenience in installation.

In summary, the invention provides a detergent dissolving box for a washing machine, which comprises a shell, wherein a placing bin for containing detergent is arranged above the shell, and a channel for water flow to pass through is arranged below the shell; a communicating bin which can communicate the placing bin and the channel and is used for detergent to enter the channel from the placing bin is arranged between the placing bin and the channel; a crushing mechanism for crushing hard particles in the detergent passing process is arranged in the communicating bin; one end of the placing bin is provided with a water inlet; the crushing mechanism comprises a fixed ring fixedly arranged at the upper end of the communicating bin, a rotating ring coaxially positioned at the lower end of the fixed ring and capable of switching forward and reverse rotation, a reciprocating rotating mechanism for driving the rotating ring to rotate and a plurality of crushing lines which are annularly arranged between the rotating ring and the fixed ring and have certain elasticity; when the device is used: rivers are followed the water inlet gets into to placing the storehouse in, and the rivers that get into to place the storehouse carry out preliminary mixing with the detergent, afterwards, rivers drive the detergent through intercommunication storehouse entering channel in.
