Description

Technical Field

[0001] The present invention relates to the technical field related to cleaning equipment, and in particular to a spray washing machine. Background Art

[0002] With the rapid development of the economy, most people will spend more time on work and study. It is especially difficult for women, including working women, to squeeze out time to deal with a large number of household clothes. Among them, mixed washing of sensitive clothes (such as underwear or other close-fitting clothes) will cause cross-infection, which is particularly prone to induce a series of diseases in women and is inconsistent with modern health requirements. In addition, women love beauty and attach great importance to hand care. Therefore, sensitive clothes washing machines specially used for washing sensitive clothes have appeared, so that sensitive clothes can be washed separately from ordinary clothes, which is convenient for washing sensitive clothes and avoids the problem of cross-contamination. The current sensitive clothes washing machines use three forms: micro-pulsator, micro-drum and micro-underwear hot extrusion, but they will cause serious deformation and damage to clothes, low washing rate, and uneven washing.

[0042] A spray structure is provided on the clothes treatment drum, and the spray structure is provided with a plurality of spray heads corresponding to the inside and outside of the clothes protection device, so as to wash both the inside and outside of the clothes during washing;

[0043] During washing, the two spray heads fixed on the clothes processing drum spray and clean the inside and outside of the clothes while the clothes protecting device rotates relative to the clothes processing drum.

[0044] The following describes the details in conjunction with specific embodiments.

[0045] refer to Figures 1 to 8One embodiment of the present invention provides a spray washing machine, which includes a protective device 1 and a clothes processing drum 2. The protective device 1 includes a hollow shell-shaped cage 1.1. The cage 1.1 is provided with a mounting portion 1.2 and a hollow clothes protective portion 1.3 from top to bottom. The clothes protective portion 1.3 can be set according to actual needs. For example, the clothes support portion 1.4 can be a cylindrical convex column for supporting and pressing against the buttocks area of ​​underwear or sleeve cotton hats, etc., or it can be a hemispherical arc-shaped convex for supporting and pressing against The cup of a bra, and so on. In this case, the clothes are prevented from deformation during washing by providing a clothes support portion 1.4. The clothes support portion 1.4 is provided on the clothes protection portion 1.3. The clothes processing drum 2 includes a bottom wall 2.1 and a side wall 2.2. The bottom wall 2.1 and the side wall 2.2 can be integrally formed to save costs. A boss 2.3 is provided in the middle of the bottom wall 2.1, which is adapted to the shape of the cage 1.1 and fixedly supports the cage 1.1. The cage 1.1 and the boss 2.3 can be in the shape of a frustum, a cylinder, a multi-faceted prism, etc. Therefore, the clothes support portion 1.4 provided in the spray washing machine of the present invention can reduce deformation damage to clothes during washing, and the hollow area of ​​the clothes protection portion 1.3 can allow washing water to pass through, thereby washing the front and back of the clothes fixed to the clothes protection portion 1.3, thereby ensuring a high cleaning rate and uniform washing of the clothes.

[0046] Specific reference Figure 8 Taking a bra as an example, compared to the normal wearing of a bra, the bra is installed in an inverted manner around the clothing protective part 1.3 and the cup part is placed on the clothing support part 1.4 to be supported and lifted up, ensuring that the bra does not slide down, and the shoulder straps on both sides of the bra are wrapped around the clothing protective part 1.3 and fastened to each other by the buckles on the shoulder straps to fix the bra on the protective device 1.

[0047] Key references and Figure 6 Figure 7 The washing machine includes a spray structure, which is arranged on the clothes processing drum. The spray structure is provided with multiple groups of spray heads, which correspond to the inside and outside of the clothes protection device respectively, so that the inside and outside of the clothes can be washed during washing; during washing, the two spray heads fixed on the clothes processing drum spray and clean the inside and outside of the clothes while the clothes protection device rotates relative to the clothes processing drum.

[0048] Specifically, in one embodiment, the spray structure further includes a first spray head 3 having a plurality of first spray holes 3.1 and a second spray head 4 having a plurality of second spray holes 4.1. The first spray head 3 is fixed on the inner wall surface of the side wall 2.2 and extends in a direction perpendicular to the bottom wall 2.1. The second spray head 4 is fixed on the outer wall surface of the boss 2.3 and extends along the generatrix direction of the boss 2.3. The plurality of first spray holes 3.1 spray liquid from the side wall 2.2 toward the boss 2.3, and the second spray holes 4.1 spray liquid from the outer wall surface of the boss 2.3 toward the side wall 2.2. The liquid can be, for example, tap water for rinsing or tap water for washing with detergent dissolved in or mixed with laundry liquid. Since the first spray head 3 and the second spray head 4 are only slightly lower than the height of the side wall 2.2, it can be ensured that the washing water is sprayed on the entire front and back of the clothes fixed on the clothing protective part 1.3, so that the front and back of the clothes are fully washed.

[0049] Key References Figure 5 In one embodiment, a first mounting groove 2.4 is provided on the inner wall of the laundry processing tub sidewall, partially protruding from the wall of the laundry processing tub 2. The first shower head 3 is secured within the first mounting groove 2.4. A pair of first ribs 2.5 are provided parallel to the outer wall of the boss 2.3, forming a second mounting groove (not shown). Multiple pairs of latches 2.6 are provided along the length of the pair of first ribs 2.5. The second shower head 4 is positioned within the second mounting groove and engages with the multiple pairs of latches 2.6. The shape of each latch 2.6 is determined based on the shape of the second shower head 4. For example, if the second shower head 4 is circular, the engaging portion of the latch 2.6 is circular. If the shape is rectangular or triangular, the shape of the latch 2.6 is modified accordingly to the second shower head 4. Thus, the provision of the first mounting groove 2.4 and the second mounting groove facilitates the convenient and secure mounting of the first shower head 3 and the second shower head 4.

[0050] In one embodiment, a plurality of second ribs 2.7 are provided on the outer wall surface of the boss, which are parallel and equidistantly arranged in the radial direction thereof, and each second rib 2.7 abuts against the inner wall surface of the clothing protective portion 1.3. In this way, the plurality of second ribs 2.7 can not only strengthen the strength of the boss 2.3 but also provide support for the clothing protective portion 1.3 of the cage body 1.1.

[0051] Key References Figure 3In one embodiment, the protective device 1 also includes a hollow tray 1.5 fixedly connected to the bottom of the cage body 1.1 and parallel to the bottom wall 2.1. The tray 1.5 is provided with a circle of flanges and reinforcing ribs 1.6 and drainage grooves 1.7 evenly distributed on its surface. The drainage grooves 1.7 are used for liquid to pass through to avoid accumulation. The tray 1.5 can hold clothes, such as bra straps, to prevent the shoulder straps from falling on the clothing treatment drum 2, thereby preventing wear caused by friction between the shoulder straps and the clothing treatment drum 2 during the operation of the spray washing machine.

[0052] Key References Figure 2 In one embodiment, the cage body 1.1 and the tray 1.5 are integrally formed, and the boss 2.3 and the bottom wall 2.1 integrally formed with the side wall 2.2 are integrally formed. In this way, the manufacturing steps are simplified and the manufacturing cost is saved.

[0053] Key References Figure 3 and Figure 8 In one embodiment, the support portion 1.4 is arranged at a position approximately in the middle of the clothing protective portion 1.3 along the longitudinal direction of the cage body 1.1 and is set as two symmetrical hemispherical arc-shaped protrusions. The shapes of the two arc-shaped protrusions are particularly similar to the shapes of two cups of a bra, which is a kind of women's special clothing. The bra can fit together with the support portion 1.4, and the support portion 1.4 applies a supporting force to the two cups to prevent deformation. In addition, the support portion 1.4 can lift the bra so that the position of the bra is fixed in the middle position of the clothing protective portion 1.3, and it will not fall onto the clothing processing drum 2 or the tray 1.5. The area where the bra is folded against each other can be reduced, allowing the liquid to fully flush all parts of the bra, thereby increasing the cleaning rate of the clothes. In addition, although bras of different sizes have different sizes and shapes, the differences are not significant. Therefore, it is only necessary to design the shape of the clothing support portion 1.4 and the shape of the cage body 1.1 to be of conventional size, and then adjust the tightening force of the bra straps and the outer periphery of the clothing protective portion 1.3 to make the protective device 1 suitable for bras of various sizes.

[0054] Key References Figure 2 and Figure 4In one embodiment, the mounting portion 1.2 includes a drive ring 1.8 disposed on the inner side of the top of the cage 1.1. The drive ring 1.8 is provided with a plurality of threaded mounting holes 1.9. The spray washing machine further includes a motor 5 and a drive shaft 6. A mounting seat 2.8 and a mounting plate 2.9 for securing the motor 5 are provided on the inner side of the top 2.3.1 of the boss 2.3. A plurality of threaded members 17 are fixedly connected to the top of the boss 2.3 via the mounting plate 2.9. The motor 5 is drivably connected to the drive shaft 6, and the drive shaft 6 passes through the top 2.3.1 of the boss 2.3. The multiple threaded members 17 are respectively fixedly connected to the multiple shaft holes and the multiple threaded mounting holes 1.9 of the drive shaft 6. The motor 5 drives the drive shaft 6 to drive the cage 1.1 to rotate. In this way, not only the internal space of the boss 2.3 is used to firmly fix the motor 5, but also the motor 5 is used to drive the cage 1.1 to rotate so that the clothes fixed on the cage 1.1 move relative to the first spray head 3 and the second spray head 4. Therefore, the multiple first spray holes 3.1 and the second spray holes 4.1 can repeatedly perform forward and reverse spray washing on the entire clothes, including the part of the clothes supported by the clothes support part 1.4, to obtain a higher washing rate.

[0055] Key References Figure 2 In one embodiment, the laundry washing device further comprises a bearing 7 arranged between the drive shaft 6 and the top of the boss 2.3. Therefore, by providing the bearing 7, the drive shaft 6 and the boss 2.3 are in indirect contact, thereby reducing the frictional resistance of the boss 2.3 to the bearing 7.

[0056] Key References Figure 5 and Figure 8 In one embodiment, the spray washing machine includes a drum through hole 8 provided on the bottom wall 2.1, a water inlet pipe 9 provided with a water inlet 9.1 and a water inlet valve 9.2, a drainage pipe 10 provided with a drainage port 10.1 and a drainage valve 10.2, a water outlet pipe 11 connected to the drum through hole 8, a first water spray pipe 12 and a second water spray pipe 13 respectively connected to the first spray head 3 and the second spray head 4, and a water pump 14 provided in the water outlet pipe and upstream of the first water spray pipe 12 and the second water spray pipe 13, wherein the drum through hole 8 is used for drainage or circulating spraying. In this way, by providing the above-mentioned various pipes, liquid can be circulated to the first spray head 3 and the second spray head 4, so that the front and back of the clothes 15 are repeatedly sprayed with circulating liquid by the first spray holes 3.1 and the second spray holes 4.1, so as to be evenly and thoroughly washed.

[0057] Key References Figure 8In one embodiment, when the spray washing machine is in the washing mode or the rinsing mode, the operation of each mode is controlled by a controller such as a CPU or a PLC. The water inlet valve 9.2 is opened, and tap water enters the clothing treatment drum 2 through the water inlet 9.1. After the tap water reaches a predetermined water level, the water inlet valve 9.2 is closed, and the water inlet is stopped. The water pump 14 and the motor 5 start to operate. The water pump 14 pumps the washing water 16 out of the clothing treatment drum 2 through the drum through hole 8, and then sprays the washing water 16 from the first spray head 3 and the second spray head 4 through the first spray pipe 12 and the second spray pipe 13 respectively. The sprayed washing water 16 has a great influence on the clothing treatment drum 2. The clothes 15 on the molded part 1.3 are sprayed and rinsed on both sides. The motor 5 drives the cage 1.1 to rotate through the drive shaft 6, so that all parts of the clothes 15 are sprayed, thereby improving the cleaning rate of the clothes 15. After the washing mode or the rinsing mode is completed, the water pump 14 and the motor 5 stop rotating, the drain valve 10.2 opens, and the washing water 16 is discharged through the drain port 10.1. Furthermore, since the rinsing mode is generally performed after the washing mode, the clothes 15 to be washed are fixed on the mold protection device 1 before the washing mode, and after adding an appropriate amount of laundry liquid into the clothes processing drum 2, washing is started. Therefore, the spray washing machine of the present invention can not only wash the clothes 15 on the front and back while preventing deformation well, but also can realize each operation with high automation.

[0058] Key References Figure 3 In one embodiment, the clothing protective portion 1.3 includes a plurality of first ribs 1.10 and second ribs 1.11, which are respectively distributed along the longitudinal direction and radial direction of the cage body 1.1. The longitudinal direction can also be understood as the busbar direction. The spacing distribution is preferably uniformly distributed with equal intervals. In this way, adjacent first ribs 1.10 and second ribs 1.11 form a through hole, which is conducive to spraying the front and back of the clothing and allowing liquid to pass through each through hole to form liquid circulation.

[0059] In one embodiment, the spacing between any two adjacent first ribs 1.10 is 10 mm to 20 mm, and the spacing between any two adjacent second ribs 1.11 is 20 mm to 40 mm. This ensures both the rigidity of the clothing protecting portion 1.3 in supporting the clothing and sufficient capacity of the liquid sprayed onto the clothing.

[0060] In one embodiment, the cross-section of the first rib 1.10 and the second rib 1.11 is circular, elliptical or rectangular with rounded corners. Therefore, by setting the cross-section to a regular shape with few edges and corners, it is possible to avoid sharp edges from scratching clothes.

[0061] Key References Figures 5 to 7In one embodiment, the first spray head 3 and the second spray head 4 are both hollow circular tubes, that is, the cross-sections of both are circular. The circular tubes can be conveniently inserted into the corresponding mounting slots from bottom to top. A plurality of first spray holes 3.1 and second spray holes 4.1 are correspondingly provided on each hollow circular tube, distributed in a row along the centerline of each tube, so that each spray head can spray a uniform amount of liquid. Furthermore, the cross-sections of the first spray head 3 and the second spray head 4 can also be different shapes such as rectangular or triangular, and the shape of each spray hole can also be circular or other shaped holes. The spray holes can be distributed in a row or in multiple rows. In the present invention, each spray head is in the shape of a circular tube, each spray hole is a circular hole, and the spray holes are distributed in a row. As for the number of spray heads, it is actually set to ensure that both sides of the clothes can be washed well. In addition, the number of spray heads can be appropriately increased to ensure the spraying force.

[0062] Key References Figures 1 to 3 、 Figure 5 、 Figure 6 and Figure 8 In one embodiment, the boss 2.3 is a hollow shell and is truncated cone-shaped together with the cage body 1.1. The cage body 1.1 is stacked on the boss 2.3 at intervals and has a common vertical axis. In the present invention, since the cage body 1.1 and the boss 2.3 are both truncated cone-shaped hollow shells, not only can a larger accommodating space be provided inside each truncated cone, but the outer surface of the truncated cone of the cage body 1.1 is conducive to the flow of liquid and the fixing and removal of clothes, and the outer surface of the truncated cone of the boss 2.3 is convenient for setting the second mounting groove and each rib.

[0063] Key References Figure 2 In one embodiment, the angle α between the generatrix of the cage 1.1 and the boss 2.3 and the vertical axis is set to 6° to 10°. In the present invention, α is set to 8°. By setting α to this appropriate angle, the upper and lower ends of the garment can be tightly attached to the garment shape protector 1.3 during installation, allowing the garment shape protector 1.3 to provide maximum support for every part of the garment and prevent deformation.
