Abstract
Description
Technical Field
[0001] The present invention relates to an electromechanical structure, which is different from the commonly seen laundry devices and relates to a device structure for brushing clothes by driving roller wheels. Background Art
[0002] Due to the current ordinary washing machines (such as drum and pulsator washing machines), even if they are very modern, they occupy a large amount of space, are relatively heavy, consume a lot of electricity and time, and consume a large amount of water. This is generally not a problem for ordinary families now, but in places where water is scarce or there is no water pipe connection, such washing machines are basically unusable. Also, in dormitories where many people live, even if there is a washing machine, it is very difficult to wait for rotation. Although there are smaller washing machines on the market now, they still cannot get rid of problems such as long washing time, not very good washing effect, and inconvenient placement during washing. Summary of the Invention
[0003] In order to solve the above-mentioned deficiencies of the current washing machines, the present model adopts a brand-new design. The present invention not only has a small structure and is easy to operate, can wash clothes of different sizes, but also washes very quickly. Therefore, it is much more convenient to place this washing machine than others, and it is a very good supplement to the existing washing machine types.
[0004] This type of washing machine is elastically composed of two groups of symmetric and structurally identical laundry structure groups through its outer shell and its connection components. For the convenience of description, the above two groups of symmetric laundry structure groups are respectively referred to as the upper laundry group and the lower laundry group. Taking the clothing inlet position as the front and the clothing outlet position as the rear - the following descriptions are based on the above description method.
[0005] Among the features of this machine, it includes the towing roller and the brush roller that directly act on the clothes, the motor, battery for driving the above rollers, and the gears for regulating the conduction of the above rollers, the outer shell, springs and brackets for elastically fitting and supporting the upper and lower two laundry groups.
[0006] In the preferred structure of this machine, the two pairs of upper and lower symmetric rollers that directly contact the clothes and affect them are involved. Among them, one pair is on the front side (i.e., close to the clothing inlet position), and there are concave and convex textures on the roller surface to prevent the roller surface from being too smooth. It is the towing roller for driving the clothes to move backward; the other pair is behind the towing wheel and is the brush roller, which is responsible for brushing the clothes brought by the towing wheel.
[0007] In order to achieve the proper washing effect, in the structure of this machine, it is preferred that the towing roller and the rear brush roller are controlled in cooperation through a gear set so that their speed ratio is below 1 / 4 (i.e., the speed of the brush roller is more than 4 times that of the towing roller). In this way, the effect of brushing the clothes in the way of fixing one end and brushing the other end of the clothes can be better achieved.
[0008] Further, the brush roller at the rear side is preferably under the cooperative control of a gear set to achieve continuous instantaneous clockwise and counterclockwise rotation switching (a one-way rotation can also be selected, but the washing effect seems not as good), and through certain means (such as gear cooperation), the time period for the clothes to be discharged and turned towards the clothes outlet position is greater than the time period for the clothes to be rolled in and turned at the clothes inlet position (simply put, when viewed from the right side of the machine, the time period for the brush roller of the upper laundry group to rotate counterclockwise is greater than the time period for it to rotate clockwise, and the time period for the brush roller of the lower laundry group to rotate clockwise is greater than the time period for it to rotate counterclockwise), so as to gradually push forward and brush the clothes, and then discharge the clothes towards the clothes outlet. Figure 1 When viewed from the right side of the machine, the time period for the brush roller of the upper laundry group to rotate counterclockwise is greater than the time period for it to rotate clockwise, and the time period for the brush roller of the lower laundry group to rotate clockwise is greater than the time period for it to rotate counterclockwise), so as to gradually push forward and brush the clothes, and then discharge the clothes towards the clothes outlet.
[0009] Further, preferably, the gear set required for the corresponding cooperation of adjusting the roller speed and direction is concentrated together and installed in a container as the gear cooperation control area for the roller direction and speed (hereinafter referred to as the gear control box). The gear control box is located on either the left or right side of the washing machine (left and right are for reference), and after the gears inside it adjust the speed or direction, the kinetic energy is transmitted through the roller shaft to drive the roller to rotate in the corresponding manner. The gear control box is also divided into two symmetrically upper and lower parts, which are respectively used as a part of the above-mentioned upper and lower laundry groups. Figure 1 Further, preferably, the gear set required for the corresponding cooperation of adjusting the roller speed and direction is concentrated together and installed in a container as the gear cooperation control area for the roller direction and speed (hereinafter referred to as the gear control box). The gear control box is located on either the left or right side of the washing machine (left and right are for reference), and after the gears inside it adjust the speed or direction, the kinetic energy is transmitted through the roller shaft to drive the roller to rotate in the corresponding manner. The gear control box is also divided into two symmetrically upper and lower parts, which are respectively used as a part of the above-mentioned upper and lower laundry groups.
[0010] Further, in the structure of this machine, preferably, the overall structure of the outer shell (i.e., the outer shell that wraps and fixes the above-mentioned upper and lower laundry groups) is a square tubular shell structure. The inner cavity width is basically the same as that of the above-mentioned upper and lower laundry groups. Since various clothes need to be loaded, the inner cavity height is several centimeters higher than the total height of the upper and lower laundry groups (generally 5 or 6 centimeters is fine). It is fixed in the outer shell with elastic components such as elastic pieces and torsion springs, and with the upper and lower planes of the inner cavity of the outer shell as the support positions, the upper and lower laundry groups are clamped in the middle, and the distance between the upper and lower laundry groups is elastically adjusted according to the thickness of the clothes transmitted between the upper and lower laundry groups.
[0011] Further, preferably, baffles are added between the clothes inlet position at the front side of the outer shell and the laundry driving roller, and between the driving roller and the brush roller to prevent clothes from overflowing during washing.
[0012] Further, preferably, except for the position occupied by the clothes discharged from the clothes outlet at the rear side of the outer shell (i.e., the side of the outer shell where the clothes outlet is located), other positions are blocked, and this blocked part serves as the support for the internal upper and lower laundry groups. When the washing machine is placed upright (i.e., when the clothes inlet of the machine is on the top and the clothes outlet position is on the bottom, there will be relevant descriptions later), it prevents the upper and lower laundry groups from sliding down (i.e., the rear side of the outer shell serves as the support component that restricts the upper and lower laundry groups within the outer shell), and confines the upper and lower laundry groups to work within the outer shell.
[0013] Furthermore, in the structure of this machine, it is preferred that on the outer casing, openings parallel to and of the same length as the brush rollers are respectively provided at positions adjacent to the brush rollers of the upper and lower laundry groups. And detergent boxes are installed on the outer sides of the upper and lower side walls of the above-mentioned outer casing. The liquid leakage heads thereof are introduced through the two openings on the above-mentioned outer casing, attached to the brush rollers, and driven by the rotation of the brushes of the brush rollers and the action of gravity, the detergent is discharged from the detergent boxes. When more laundry detergent needs to be added for washing, the laundry detergent can be replenished in real time through the above method.
[0014] Furthermore, it is preferred that in this machine, in addition to the power supply switch, there is also a steering changeover switch, aiming to provide another option for people to wash clothes with this machine. With only the power switch, only the power switch can be turned on first, the clothes are put into the clothes inlet, taken out by the towing roller and the brush roller, and the clothes are discharged from the clothes outlet, completing one scrubbing process of one piece of clothing. The above is the first laundry option. With the steering changeover switch, the power switch can be turned on first, the steering changeover switch is switched to the forward direction, then the clothes are put into the clothes inlet, washed by the towing roller and the brush roller to about half, the steering changeover switch is switched to the reverse direction, the motor reverses, and the clothes are discharged from the clothes inlet position of this washing machine. The clothes are taken out and re - put on the other side as before, washed for the other half by the towing roller and the brush roller, and then discharged from the clothes inlet again, completing one scrubbing process of one piece of clothing. The above is the second laundry option. In the second option, the clothes inlet is also the clothes outlet. For the convenience of description, in the whole specification, unless otherwise specified, the clothes inlet and the clothes outlet are expressed in terms of the clothes inlet and the clothes outlet of the first option.
[0015] During actual use, it is preferred that the above - mentioned washing machine is mounted on the barrel wall through a bracket (the bracket can be made into a handle), so that the clothes inlet position of this washing machine is above and the clothes outlet position is below, suspended in the barrel. Then water, or detergent, or its dilution, or detergent is injected into the detergent box. Then, the first laundry option or the second laundry option is selected to complete the brushing task of the clothes. Description of the Drawings

[0027] To more clearly understand the above objects, features, and advantages of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.
[0028] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.
[0029] For the convenience of subsequent description, the clothing inlet position is defined as the front (i.e., Figure 1 the shown clothing inlet position is the front), and the clothing outlet position is defined as the rear (i.e., Figure 7 the shown clothing outlet position is the rear), and the upper, lower, left, and right directions are based on the perspective of an observer in contrast to Figure 1 、 Figure 2 for reference.
[0030] In a preferred embodiment of this washing machine, since this washing machine needs to complete the brushing work of clothes in an environment of detergent and water, there are certain requirements for corrosion resistance and mechanical strength. At the same time, considering being relatively inexpensive and lightweight, the preferred materials for this washing machine embodiment are as follows: The outer shell 2 is made of 6061 aluminum alloy with a thickness of 5 mm. For the rear-end gear set 10, since it needs to quickly switch between forward and reverse rotations during operation and considering the requirements of reducing momentum and having greater mechanical strength, the bevel gears and the incomplete bevel gear mechanism of the rear-end gear set 10 in this embodiment are made of 7075 aluminum alloy material, with a maximum diameter set at 22 mm and a cone angle of 45 degrees. Other mechanical parts are all made of stainless steel material. The thickness of the gear control box shell 11 is 2 mm, the thickness of the spur gears and the worm gears is 15 mm, the wire diameter of the torsion spring is 1.5 mm, the diameter of the transmission shaft is 8 mm, and the thickness of the components of other mechanical parts with relatively small mechanical strength is 1 mm. In short, within its limited space, while ensuring the normal operation of its mechanical components, their mechanical strength is ensured as much as possible. The motor selected is a medium-power brushless motor with a power of more than 200 W. The above description in this paragraph only serves to make this embodiment as feasible as possible, and the special requirements for the component materials are only for reference.
[0031] In the above preferred embodiment of this washing machine, it is divided into a power drive part, a gear control part, a part that directly acts on the clothes, an auxiliary laundry accessory part, and the outer shell 2.
[0032] In the above preferred embodiment, the power motor drive part includes a power source 1, a wire 6, and a motor 3 inside the motor box. The above power source 1 supplies power to the motor 3 inside the motor box through the wire 6. After the motor 3 receives power, it drives the gears inside the gear control box (gear control part) to rotate through a coupling 16 and a transmission shaft 15.
[0033] In the above preferred embodiment of the washing machine, the gear control box (gear control part) is located on the right side of the machine and includes a transmission shaft 16, a front-end gear set (composed of a spur gear set 14 and a worm gear set 12), a rear-end gear set 10, a shaft bracket, and a fixed housing 11 of the gear control part.
[0034] The front-end gear set includes a pair of spur gear sets 14 (a combination of spur gear sets 14-1 and 14-2) and a pair of worm and worm gear sets 12 (a combination of worm gears 12-2 and worm shafts 12-1). One spur gear 14-1 of a pair of spur gears 14 in these two groups of gears is coaxially driven with one worm shaft 12-1 of the other pair of worm and worm gears 12 to form a reduction gear set to drive the front roller, running at a speed 20% lower than the speed of the front-end motor.
[0035] In the preferred embodiment of the above rear-end gear set, the brush roller 17 is adjusted to rotate in a clockwise and counterclockwise manner through gears. The rear-end gear set preferably consists of a bevel gear and two incomplete bevel gear mechanisms. The bevel gear 10-3 coaxial with the brush roller is a complete bevel gear. The two incomplete bevel gear mechanisms (incomplete bevel gear mechanisms 10-1 and 10-2) with opposite tips on the motor transmission shaft 15 have teeth in some sections and no teeth in some sections. As Figure 5 shown, it is preferred that the tooth profiles of the opposite incomplete bevel gear mechanisms are the same and complementary, that is, the teeth of the toothed section of one incomplete bevel gear mechanism just form a complete, defect-free and non-deformed gear with the teeth of the toothed section of the other opposite incomplete bevel gear mechanism. The toothed parts of the two incomplete bevel gear mechanisms with opposite tips mesh with the complete bevel gear coaxial with the brush roller at different times, and the toothed section covering area that drives the clothes towards the clothes outlet is larger, which is beneficial to the discharge of clothes, rather than just relying on gravity for discharge (when in use, it is preferred that the clothes inlet is at the top and the clothes outlet is at the bottom, so gravity plays a part in discharging from the clothes outlet). (Assuming the motor rotates clockwise), this requires that the toothed section covering area of the front incomplete bevel gear mechanism 10-1 of the upper washing group is less than the toothed section covering area of the rear incomplete bevel gear mechanism 10-2. The ratio of the toothed section covering areas of the former to the latter is set to 2:3. In this embodiment, the lower washing group is the opposite, that is, the toothed section covering area of the lower washing group symmetric with the front incomplete bevel gear mechanism 10-1 of the upper washing group is larger than the toothed section covering area of the lower washing group symmetric with the rear incomplete bevel gear mechanism 10-2 of the upper washing group. The ratio of the toothed section covering areas of the incomplete bevel gear mechanism of the lower washing group in this embodiment is set to 3:2. Moreover, the toothed section covering areas between the upper and lower washing groups of the front bevel wheels and between the upper and lower washing groups of the rear bevel wheels are staggered by an angle (the required staggering angle is not very strict, and a staggering angle greater than 20 degrees has a better effect). The purpose is to achieve the effect of rubbing the clothes as if by hand.
[0036] In the above-mentioned preferred embodiment of the washing machine, in the direct clothing acting area, in addition to the dragging roller 9 and the brush roller 17 mentioned above, it also includes the left bracket 20 for fixing the roller shaft, the torsion spring 8, the front baffle 18, the supporting spring piece 19, and the rear baffle 21. The width of the washing machine from left to right occupied by the dragging roller 9, the brush roller 17, the front baffle 18, the rear baffle 21, and the inlet and outlet of the clothing is set to 28 cm (slightly larger than half of the width of ordinary adult clothing).
[0037] In the above-mentioned preferred embodiment of the washing machine, the dragging roller 9 and the brush roller 17 are of the structures of the general seen dragging roller and brush roller, and the dragging roller is preferably provided with some concave and convex textures. The above-mentioned left bracket 20 is located at the left terminal position of the front and rear roller shafts and is used to fix the dragging roller 9 and the brush roller 17. The above-mentioned front baffle 18 (one end is fixed by a shaft and can rotate, and the other side that does not contact the clothing is supported by the supporting spring piece 19), and the rear baffle 21 is fixed on the left bracket and the outer shell 11 of the gear control area by rivets or screws. The above-mentioned front baffle 18 and the rear baffle 21 both prevent the clothing from overflowing during the transmission process.
[0038] In this embodiment, the above-mentioned torsion spring 8 is fixed on the torsion spring shaft 7. One end of the torsion arm leans against the protrusion 2(1) of the outer shell 2 (the protruding part of the outer shell near the torsion spring 8), and the other end of the torsion arm hub is at both ends of the roller shaft. While one end of the torsion arm of the torsion spring presses the roller shaft, the other torsion arm borrows force from the outer shell. In addition, the groove 2(2) of the outer shell limits the up and down movement of the torsion spring shaft 7. The middle of the torsion spring shaft 7 is combined with a square slider into a fixed solid structure, which cooperates with the protrusions 2(3) of the outer shell on both sides of its square slider structure, so that the torsion spring shaft 7 is limited to the behavior range of only sliding back and forth. Under the above conditions, the elastic force of the torsion spring on both sides of the roller shaft is used to elastically clamp the upper and lower laundry groups together. When the clothing comes, the upper and lower laundry groups can clamp the clothing well under the pressing of the above-mentioned torsion spring, so that the clothing can be carried out of the outlet under the dragging of the front and rear roller wheels (the above-mentioned dragging roller and brush roller).
[0039] The auxiliary laundry accessory is mainly the detergent box 5. One part of it is attached to the outside of the outer shell 2, and the detergent box 5 is buckled on the outer shell 2 with the snap button 5(1). The other part needs to first open a slender opening on the outer shell 2 and near the brush roller 17, which is parallel to the brush roller 17 and has the same length as the brush roller 17 and a width of about 2 cm. The other part of the detergent box 5 extends from the above-mentioned slender opening to the position of the brush of the brush wheel and opens a slender opening with a width of about 1 or 2 millimeters as the liquid leakage head of the detergent box 5. When additional laundry detergent needs to be added during washing, it can be supplemented through the liquid leakage head of the detergent box 5.
[0040] The above-mentioned handle 4 is installed at the positions near the plane of the clothing inlet at both left and right ends of the washing machine. Since the clothing inlet is at the top and the clothing outlet is at the bottom during actual laundry, perpendicular to the ground, and it is placed on the upper end of the side wall of the water bucket through the handles on both sides of the machine. That is to say, the handles on both sides of the machine play a role in fixing and supporting the washing machine.
[0041] The above-mentioned outer shell 2 that has been mentioned all the time. In addition to the above-mentioned cooperation features with other components in this embodiment, it is preferably a square tubular shell structure composed of two upper and lower parts, namely 2(5) (the upper part of the outer shell) and 2(6) (the lower part of the outer shell) (slightly different, there are seals at positions 2(7) and 2(8)). It is fixed on the left and right sides by the screw fixing positions 2(4). On the plane of the clothing outlet of the outer shell 2 of the machine, except for the space occupied by the clothing outlet, the positions 2(7) and 2(8) at other places are sealed. When the clothing inlet is at the top and the clothing outlet is at the bottom, perpendicular to the ground and placed on the upper end of the bucket wall during actual laundry (there are relevant descriptions later), with the rear side of the left bracket 20 and the rear side of the gear control box shell on the right as the support stress positions, and the sealed parts on the left and right sides of the clothing outlet of the outer shell 2 as the support force application positions, the upper and lower laundry groups in the outer shell 2 are restricted within the outer shell 2 and do not fall out of the outer shell 2. In order for the upper and lower laundry groups in the outer shell 2 to slide smoothly during laundry, the rear sides of the left bracket 20 and the rear side of the gear control box shell 11 on the right are both made into arcs from top to bottom, as Figure 7 shown.
[0042] This embodiment of the washing machine also includes that it needs to be used in cooperation with a corresponding water bucket. The cross-sectional diameter of the water bucket to be matched is equivalent to the distance between the two handles 4 on both sides of the machine. In this embodiment, it is preferably 35 cm. There is a cooperation with the water bucket such that there is at least the space occupied by one or two pieces of clothing from the plane of the clothing outlet of this washing machine to the bottom of the bucket. In this embodiment, it is preferably 20 cm. The machine is placed on the upper end of the bucket wall through the handles on both sides, so that the clothing inlet of the machine is above, and it is vertically suspended inside the bucket, as Figure 9 shown.
[0043] Based on the above, the preferred embodiment of this washing machine further includes two switches (power switch 1(1) and steering switch 1(2)), enabling the machine to have two usage scenarios. Before using the scenarios, first load an appropriate amount of aqueous solution diluted with laundry detergent into the barrel (the aqueous solution only needs to reach the position of the brush roller). The washing machine is placed on the corresponding barrel by the method described above. Then, select a scenario. In Scenario 1, first turn on the power switch 1(1), and then switch the steering switch 1(2) to the forward direction. Put the clothes at the clothing inlet, and they are taken out through the towing roller 9 and the brush roller 17, completing the process of scrubbing one piece of clothing once during the washing process. In Scenario 2, use a bidirectional rotating motor. First turn on the power switch 1(1), and then switch the steering switch 1(2) to the forward direction. Wash the clothes through the towing roller 9 and the brush roller 17 until about half of the washing process is completed. Then switch the steering switch 1(2) to the reverse direction, and the motor rotates in reverse to discharge the clothes to the clothing inlet position of the washing machine. Replace the clothes with the opposite side as before and put them back in, wash the other half through the towing roller 9 and the brush roller 17, and then discharge them from the clothing inlet again. Only then is the washing process of Scenario 2 completed. And during this discharging process, while the towing roller 9 is towing the clothes out, it also has an extrusion and drainage effect on the clothes. Laundry detergent in the detergent box can also be used during washing to enhance the usage effect.
[0044] As can be seen from the above, this washing machine has a very fast washing speed, saves water and electricity, is small in size and convenient to carry. The washing process is relatively easy and elegant. Although it cannot replace the traditional pulsator washing machines and drum washing machines we usually use, it has its unique advantages in some cases.
