Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Referring to fig. 3 and 4, the pulsator washing machine according to the embodiment of the present invention includes a casing 1, a washing tub is disposed in the casing 1, and an auxiliary water inlet device 2 communicated with a water inlet valve, wherein the auxiliary water inlet device 2 is switchable between an extended state and a retracted state, and when the auxiliary water inlet device 2 is in the extended state, a water outlet 21 of the auxiliary water inlet device 2 is opposite to a central region of a mouth of the washing tub.
Because the auxiliary water inlet device 2 is communicated with the water inlet valve and can be switched between an extending state and a contracting state, when the auxiliary water inlet device 2 is in the extending state, the water outlet 21 of the auxiliary water inlet device 2 is opposite to the middle area of the opening of the inner barrel, so that when the washing machine is used for water inlet, water flowing out from the water outlet 21 of the auxiliary water inlet device 2 can enter the inner barrel from the middle area of the opening of the inner barrel and fully contact with clothes in the middle area of the inner barrel to moisten the clothes, and because the water entering the middle area of the inner barrel is easily diffused to the periphery along gaps of the clothes before reaching the bottom of the inner barrel, the water is fully contacted with the clothes around the inner barrel and moistens the clothes in the periphery of the inner barrel in the process of diffusing to the periphery, therefore, when the auxiliary water inlet device 2 is used for water inlet, the water outlet is opposite to the middle area of the opening of the inner barrel, the water flowing out from the, thereby improving the washing efficiency of the pulsator washing machine. Wherein, the middle area refers to the area close to the center of the bung hole of the inner barrel.
It should be noted that: as shown in fig. 3, the auxiliary water inlet device 2 may be installed not only at the rear side of the enclosure frame but also at the left and right sides of the enclosure frame.
The pulsator washing machine washes the laundry by using a friction force between water current generated by a rotating pulsator and the laundry, but the pulsator washing machine cannot clean the dirt on the laundry, especially hard dirt or small dirt, sometimes, in order to solve the problem, as shown in fig. 5 and 6, an annular outer tub cover is arranged at a tub opening of the outer tub, and a pre-washing tub 3 is arranged at a through hole of the outer tub cover. The clothes to be washed with hard dirt or small stains can be manually pre-washed by using the pre-washing basin 3 before being put into the washing machine, and the clothes and washing water can be poured into the washing machine together for washing after the pre-washing is finished, so that the washing water can be saved, and the washing effect of the washing machine can be improved; simultaneously, in order to make things convenient for the intaking of prewashing basin 3 in advance, when supplementary water installations 2 was located the extended position, supplementary water installations 2's delivery port 21 should set up with prewashing basin 3 is relative, in the prewashing basin 3 that the water that flows out from supplementary water installations 2's delivery port 21 just can directly get into like this to made things convenient for the convenience of user's water injection in to prewashing basin 3 in advance.
In order to enhance the effect of wetting the clothes in the inner tub with the water flowing out from the water outlet 21 of the auxiliary water inlet device 2, as shown in fig. 8, the diameter of the water outlet 21 of the auxiliary water inlet device 2 is gradually enlarged along the water outlet direction (for example, the cross section of the water outlet can be trapezoidal), so that under the action of internal water pressure, the water is sprayed out from the water outlet and then is in a conical shape, the wetting area of the water on the clothes in the inner tub is increased, and the effect of wetting the clothes in the inner tub with the water is enhanced.
The structure of the auxiliary water inlet device 2 is not unique, for example, the auxiliary water inlet device 2 may have the following structure: the auxiliary water inlet device 2 comprises a shell 22, a sliding cavity 23 is arranged in the shell 22, a telescopic pipe 24 is arranged in the sliding cavity 23 in a sliding fit mode, a water outlet 21 of the auxiliary water inlet device 2 is formed in the telescopic pipe 24, a water inlet 25 of the auxiliary water inlet device 2 is formed in the shell 22, the water inlet 25 of the auxiliary water inlet device 2 is communicated with the sliding cavity 23 and a pipe cavity of the telescopic pipe 24 respectively, a rack is fixed on the outer side pipe wall of the telescopic pipe 24, a motor is fixedly arranged on the shell 22, a gear is sleeved on a motor shaft and meshed with the rack, and the telescopic pipe 24 can slide between an extending position and a withdrawing position relative to the shell 22 under the driving of the motor and a gear-rack mechanism.
As shown in fig. 7 and 8, the auxiliary water inlet device 2 may have the following configuration: the auxiliary water inlet device 2 comprises a shell 22, a sliding cavity 23 is arranged in the shell 22, an expansion pipe 24 is in sliding fit in the sliding cavity 23, the expansion pipe 24 can slide between an extending position and a retracting position relative to the shell 22, a water inlet 25 of the auxiliary water inlet device 2 is arranged on the shell 22, the water inlet 25 of the auxiliary water inlet device 2 is respectively communicated with the sliding cavity 23 and a pipe cavity of the expansion pipe 24, a water outlet 21 of the auxiliary water inlet device 2 is arranged on the expansion pipe 24, the area of the water inlet 25 of the auxiliary water inlet device 2 is larger than that of the water outlet 21 of the auxiliary water inlet device 2, when the water inlet valve 5 is opened, water enters the sliding cavity 23, since the area of the water inlet 25 of the auxiliary water inlet device 2 is larger than the area of the water outlet 21 of the auxiliary water inlet device 2, thus, a certain water pressure is formed between the inner sides of the water outlets, and the telescopic tube 24 can slide to the extended position under the action of the water pressure. When the water intake is complete, a restoring force may be applied to bellows 24 to retract bellows 24, such as by manually retracting bellows 24. Above-mentioned two kinds of schemes (namely motor drive scheme and water pressure drive scheme) can both realize flexible pipe 24 and slide between the position of stretching out and withdrawing, nevertheless compare with the scheme that flexible pipe 24 slided between the position of stretching out and withdrawing with motor drive, utilize water pressure to drive flexible pipe 24 and slide to the position of stretching out, this kind of scheme simple structure, easy realization, the reliability is high, does not need annexes such as motor moreover, is favorable to reduce cost, the maintenance of being convenient for.
The structure of the telescopic pipe 24 is not unique, for example, the telescopic pipe 24 may only include one telescopic pipe section, and as shown in fig. 8, the telescopic pipe 24 may also include a plurality of telescopic pipe sections that are slidably, sealingly sleeved, the outer end pipe orifice of the innermost telescopic pipe section 241a is closed, the inner end pipe orifice is communicated with the sliding cavity 23, the water outlet 21 of the auxiliary water inlet device 2 is opened on the side wall of the telescopic pipe section, when the water inlet valve 5 is opened, the water pressure formed in the sliding cavity 23 may drive the plurality of telescopic pipe sections to sequentially extend out of the housing 22, and the auxiliary water inlet is realized through the water outlet 21 arranged on the telescopic pipe section. Compared with the telescopic pipe 24 only comprising one telescopic pipe section, the telescopic pipe 24 comprising a plurality of telescopic pipe sections sleeved in a sliding sealing manner can extend out the water outlet 21 of the auxiliary water inlet device 2 to a preset position through the sequential extension of the plurality of telescopic pipe sections, so that the length of the sliding cavity 23 in the shell 22 of the auxiliary water inlet device 2 is unnecessarily long, the length of the shell 22 of the auxiliary water inlet device 2 can be further reduced, and the occupied space of the auxiliary water inlet device 2 can be reduced when all the telescopic pipe sections are retracted. The number of the telescopic pipe sections may be 2, 3, etc., and is not limited herein.
When the auxiliary water inlet device 2 is used for water inlet, the water inlet valve 5 is opened, water enters the water pressure formed in the sliding cavity 23 to drive the telescopic pipes 24 to slide to the extending positions, after water inlet is finished, the plurality of telescopic pipe sections need to be sequentially retracted in order to not occupy space, in order to achieve automatic retraction of the plurality of telescopic pipe sections, as shown in fig. 8, the reset pieces 4 are arranged between the telescopic pipes 24 and the shell 22 and between two adjacent telescopic pipe sections, the reset pieces 4 are used for applying reset force to the telescopic pipe sections to move to the retracting positions, and therefore after water inlet is finished, the telescopic pipe sections achieve automatic retraction under the action of the reset force. When the water inlet valve 5 is opened, water enters the sliding cavity 23, and the water pressure formed in the sliding cavity 23 can overcome the resetting force of each resetting member 4 and drive the plurality of telescopic pipe sections to sequentially extend out of the shell 22, so that the extension of the plurality of telescopic pipe sections is completed, as shown in fig. 10.
Because the restoring force is always applied to each telescopic pipe section, if the restoring force is too large, when the auxiliary water inlet device 2 is used for water inlet, the water pressure is not easy to enable each telescopic pipe section to smoothly extend out, therefore, on the premise of not influencing the retraction of each telescopic pipe section, the restoring piece 4 is required to be as small as possible, so that when the water inlet valve 5 is opened, the water pressure formed in the sliding cavity 23 can easily overcome the restoring force of each restoring piece 4 and drive the plurality of telescopic pipe sections to sequentially extend out of the shell 22, when all the telescopic pipe sections extend out of the shell 22, the water outlet 21 of the auxiliary water inlet device 2 is opposite to the barrel mouth of the inner barrel, and thus water can directly enter the inner barrel after flowing out from the water outlet 21 of the auxiliary water inlet device 2 and can wet clothes in the inner barrel.
The type of the restoring member 4 is not unique, for example, in two adjacent telescopic tube sections 241, the inner wall of the outer end of the telescopic tube section located at the outer layer is provided with a first flange 2411 extending in the radial direction, the outer wall of the inner end of the telescopic tube section located at the inner layer is provided with a second flange 2412 extending in the radial direction, and the air bag is located between the first flange 2411 and the second flange 2412, so that after the plurality of extended tube sections are extended, the distance between the first flange 2411 and the second flange 2412 is reduced to compress the air bag to generate restoring force, and after the auxiliary water inlet device 2 finishes water inlet, the plurality of extended tube sections are retracted under the effect of the restoring force of the air bag.
In addition, as shown in fig. 8, the restoring member 4 may also be a spring, in two adjacent telescopic pipe sections, a first flange 2411 extending in the radial direction is arranged on an inner wall of an outer end (i.e., an upper end of the telescopic pipe section on the outer layer in the figure) of the telescopic pipe section on the outer layer, a second flange 2412 extending in the radial direction is arranged on an outer wall of an inner end (i.e., a lower end of the telescopic pipe section on the inner layer in the figure) of the telescopic pipe section on the inner layer, and the spring is located between the first flange 2411 and the second flange 2412, so that when the plurality of extended pipe sections are extended, a distance between the first flange 2411 and the second flange 2412 is reduced to compress the spring, thereby generating the restoring force, and when the auxiliary water inlet device 2 finishes water inlet, the plurality of extended. Compare the gasbag, spring simple structure, the reliability is high, is difficult to damage, and the space that the spring occupied is smaller in addition, can reduce each flexible pipeline section pipe diameter of messenger, and then reduces supplementary water installations 2's occupation space.
Meanwhile, as shown in fig. 8, the outer wall of the inner end of the outermost telescopic pipe section 241b is provided with a third flange 2413 extending in the radial direction, and a spring is also provided between the wall surface of the sliding cavity 23 away from the opening edge of the water inlet and the third flange 2413, as shown in fig. 10, after the outermost telescopic pipe section 241b extends out of the housing 22, the distance between the wall surface of the sliding cavity 23 away from the opening edge of the water inlet and the third flange 2413 is reduced, the spring is compressed to generate a restoring force, and after the water inlet of the auxiliary water inlet device 2 is finished, the outermost telescopic pipe section 241b is retracted under the restoring force of the spring.
To ensure that the second flange 2412 is sealed with the inner wall of the outer telescoping section during telescoping between telescoping sections, the second flange 2412 is a sliding fit with the inner wall of the outer telescoping section as shown in fig. 8, and the second flange 2412 is made of a rubber material. Because the rubber has good elasticity and wear resistance, the second flange 2412 made of rubber can be tightly matched with the inner wall of the outer layer telescopic pipe section in the telescopic sliding process of each telescopic pipe section, so that water is prevented from entering the space between the first flange 2411 and the second flange 2412 and contacting with the spring, and good sealing performance of the second flange 2412 in the sliding process of the inner wall of the outer layer telescopic pipe section is ensured.
Meanwhile, in order to ensure that the outermost telescopic pipe section 241b is sealed with the inner wall of the sliding cavity 23 of the housing 22 during the telescopic process, as shown in fig. 8, the third flange 2413 is in sliding fit with the inner wall of the sliding cavity 23, and the third flange 2413 is also made of a rubber material, so that water is prevented from entering a space between the wall surface of the opening edge of the sliding cavity 23 far away from the water inlet and the third flange 2413 and contacting with a spring, and the outermost telescopic pipe section 241b is ensured to be sealed with the inner wall of the sliding cavity 23 of the housing 22 during the telescopic process.
The structure of the casing 22 of the auxiliary water inlet device 2 is not exclusive, for example, the casing 22 may be a rectangular parallelepiped shell structure, and as shown in fig. 7, the casing 22 may also be a tubular structure, which occupies a smaller space than the rectangular parallelepiped shell structure. Specifically, the housing 22 includes a tube 221 and an end cover 222 detachably connected to a tube opening at an inner end of the tube 221, the water inlet 25 of the auxiliary water inlet device 2 is opened on the end cover 222, and the sliding cavity 23 is a tube cavity of the tube 221. Because the end cover 222 is detachably connected to the inner end pipe opening of the pipe body 221, when each telescopic pipe section is damaged or is unsmooth in the telescopic process, the damaged telescopic pipe section can be conveniently replaced or the failure of unsmooth telescopic can be conveniently eliminated. The end cap 222 can be fastened to the fastening hook 2211 on the inner end pipe opening side wall of the pipe body 221 through a fastening 2221.
Referring to fig. 8, when the telescopic tube 24 is in the retracted position, since the restoring force of the spring is always applied to each telescopic tube section, if the end cover 222 is not provided with a limitation on the final retracted position of each telescopic tube section, the inner-layer telescopic tube section and the telescopic tube section 241b which is easily retracted into the outer-layer telescopic tube section or the outermost telescopic tube section are retracted into the tube cavity of the tube body 221, so as to be unfavorable for the next extension of each telescopic tube section.

Because the water outlet 21 of the auxiliary water inlet device 2 is arranged on the side wall of the innermost telescopic pipe section 241a, when the innermost telescopic pipe section 241a is in the retraction position, the water outlet 21 of the auxiliary water inlet device 2 is positioned in the outer telescopic pipe section, so that water flowing out of the water outlet easily enters the space between the innermost telescopic pipe section 241a and the adjacent telescopic pipe section, and the water cannot be discharged and is in contact with the spring to easily cause the spring to rust. In order to solve the problem, the water retaining ribs 27 are arranged in the adjacent telescopic pipe sections, when the innermost telescopic pipe section 241a is in a contracted state, the water retaining ribs 27 can block the water outlet 21 of the auxiliary water inlet device 2, so that water flowing out of the water outlet is prevented from entering the space between the innermost telescopic pipe section 24 and the adjacent telescopic pipe section, and the spring is prevented from rusting when encountering water.
The water outlet 21 of the auxiliary water inlet device 2 may be provided on the side wall of the innermost telescopic pipe section 241a, on the side wall of the outermost telescopic pipe section 241b, on the telescopic pipe section between the outermost and innermost telescopic pipe sections, or on all the telescopic pipe sections at the same time (the water spray area may be increased).
