a washing machine

technical field

The invention relates to a washing machine.

Background technique

In recent years, with the development of the economy and the continuous improvement of people's living standards, household appliances have become an indispensable part of residents' lives. "The phenomenon makes people urgently feel the importance of energy saving. Today, China has become one of the world's largest manufacturing bases of home appliances and the largest consumer market, and the issue of energy saving in home appliances has become increasingly prominent. Since my country has revised the energy efficiency standards of washing machines since 2001, and officially implemented the "Limited Values of Power Consumption and Energy Efficiency Levels of Household Electric Washing Machines" standard on October 1, 2013, the development of washing machines in my country has continued to focus on energy conservation and environmental protection. Forward, innovative technologies such as human-powered washing machines have also been developed, marking that the energy efficiency level of washing machines has entered a new stage of development, and will become the core content of the next transformation and upgrading of the washing machine industry.

As the weather gets hotter, people wear fewer and fewer clothes. Unlike winter clothes, clothes in spring and summer are relatively thin and frequently changed. Therefore, if you use a large-capacity washing machine to wash, it will Consumption of water and electricity. In addition, children's clothes need to be washed separately from adults' clothes. In order to avoid cross-infection, underwear also needs to be washed separately from bulky clothes.

The types of washing machines currently in use are as follows:

1. A pulsator washing machine. The microcomputer controls the washing and drying. The rotation of the wave wheel at the bottom causes mutual friction between water and clothing, clothing and clothing, clothing and the wall of the cylinder, and there are also processes of winding, kinking and untwisting to wash the clothes. Although it saves time and labor, it consumes electricity and water, and the clothes are easy to tangle, and the cleaning performance is not good; and the washing machine itself is not easy to clean.

2. Drum type washing machine. Microcomputer control, no entanglement of clothes, it is the washing method that will least damage clothes. Through the rotation of the inner cylinder, the clothes and water are lifted up and down, and the temperature is continuously heated, so that the detergent can fully penetrate into the inside of the clothes, and the clothes are washed by squeezing, beating or moving and lightly rubbing the porous inner wall. In the washing process, it does not entangle, washes evenly, and has little wear and tear. It is suitable for washing wool, cashmere, silk, and pure wool fabrics. But it is time-consuming, the time is several times that of ordinary ones, and once the door is closed, it cannot be opened during the laundry process, the cleaning power is not strong, and the washing machine itself is not easy to clean.

3. Stirring washing machine. Clothes have the strongest cleaning power and save washing powder. A washing machine that soaks the laundry in washing water and relies on the reciprocating motion of the stirring blades for washing. However, it is easy to entangle, and compared with the first two methods, it is more destructive and noisy.

Aiming at the relatively few applications of washing clothes, a manual washing machine has appeared, such as the Chinese patent document CN203007657U, which adopts a pressing rod that converts linear motion into rotation, wherein the pressing rod is made of an internal spiral type, and the pressing rod is used to The matching column drives the disturbance wheel to rotate, thereby forming the agitation of the water. Generally speaking, in order to form an effective way of driving through the thread, the helix matched with the thread needs to have a relatively large lead, or use a multi-thread thread, and at the same time, it is limited by the thread profile, which will inevitably cause difficulty in the production of the pressure rod. Relatively large, and therefore cause more severe wear on the thread flanks.

detailed description

Referring to accompanying drawings 1 to 3 of the specification, a washing machine is a manual washing machine, which converts the up and down movement of the pressure rod 1 into the rotation of the pulsator 7, so its basic structure includes:

The casing 9 has a cavity, and the upper end is equipped with a top cover 2, wherein the cavity is used to accommodate internal components and form a space for placing clothes. Since it is manually driven, its individual will not be too large according to general understanding, such as background technology As mentioned in the section, it is mainly used for washing summer clothes or children's clothes, for example.

One side of the bottom of the casing 9 is provided with a tap water plug 10 , and the drain plug 10 can also be directly arranged at the bottom of the casing 9 .

The drainage structure can also be a pipeline structure, that is, a drainage hole is set at the bottom of the casing 9, and then a hose is connected to pour out the water.

Regarding the addition of water, in the structure shown in Figure 1, the top cover 2 can have holes for adding water or clothes, and the top cover 2 and the casing 9 can also adopt a quick connection structure, such as the lock mentioned later Attaches for easy loading of laundry and filling of water.

Adding water can also be equipped with adding water pipes or opening water adding valves.

As a general configuration of a washing machine, as shown in Figures 1 and 2, a pulsator 7 is configured, which is arranged at the bottom of the cavity through a slewing support. When the pulsator 7 is driven to rotate around the slewing support, it will drive the clothes and stir them. water to complete the wash.

As a general configuration of the washing machine, the pulsator 7 will not be elaborated further.

As a general configuration of a washing machine, the inner tub 8 is generally formed by winding a porous plate, and is usually arranged coaxially with the pulsator 7; in order to improve the cleaning effect, the wall surface of the inner tub 8 is often not a smooth structure. There are structures such as ridges.

In order to meet the needs of cleaning and dehydration steps, a clutch assembly is configured for the disengagement or engagement of the pulsator 7 and the inner tub 8, wherein, when disengaged, it is used for cleaning, and when engaged, it is used for dehydration.

Further, as shown in FIG. 1, a rotating rod 5 is configured, which is connected with the pulsator 7 through a transmission mechanism, and is used to drive the pulsator 7 to rotate. The rotating rod 5 is a barrel-shaped part with a first The inner drum, the first inner drum is used as a guide structure in addition to accommodating some components, so as to improve the reliability of the straight running structure.

In order to realize the conversion of linear motion and rotation, a screw drive assembly is provided, which includes a first part that is arranged in the first inner drum and has a spiral shape and a second part that cooperates with the first part to run along the spiral shape. Parts, different from the existing threaded fit, here adopts a spiral of flowers, wherein the first part is fixedly connected with the rotating rod 5, and the first part is a strip-shaped piece that is twisted around the central axis of its strip-shaped direction. become.

The strip sheet is a generalized cuboid structure, which has a relatively small thickness, a relatively large length and a certain width.

In this embodiment, the sheet-like piece should be made of plastic material, preferably metal material, such as the spiral flat steel shown in Figure 1, which is processed from flat steel.

The central axis should be understood to be the axis where the center line of the two faces defined by the thickness side and the width side (a cuboid is a hexahedron, and the opposite sides are the same rectangle) is located.

Then according to produce spiral structure as shown in Figure 3, its cross-section remains rectangular substantially, and the size of the helix angle that the blank of same length forms such as spiral flat steel 3 depends on the number of revolutions that turn, thereby, helix angle is relatively easy to control.

According to the produced first part, such as the spiral flat steel 3 shown in Fig. 3, its main force-bearing surface is the side defined by the length side and the width side, and the contact area is relatively large, so the reliability is relatively good. The lifespan will also be longer.

As regards the second part, in order to form a fit with the first part, a helical seam should be provided.

Further, regarding the pressing rod 1, it is connected with the second component, as shown in FIG. 3, and passes through the upper part of the top cover 2, as shown in the right end of FIG. 1, for driving the second component in the axial direction.

In order to realize the reciprocating motion, a reset device needs to be configured for the reset of the pressing rod 1 . The spring 4 shown in FIG.

The pressure bar 1 can also be the same as the rotary bar 5, using a barrel-shaped part, opposite to the rotary bar 5, to form an inverted barrel-shaped part, and the inner drum is marked as the second inner drum, and the two barrel-shaped Guidance can be generated between the parts. For example, the pressure rod 1 as shown in Figure 3 can be guided to the rotating rod 5. Of course, there is both linear motion and rotation between the two. If sealing is required, the sealing is difficult Relatively large.

In addition, the barrel structure does not mean that the wall of the barrel is completely closed. It can have side holes or other hollow structures, so there is no problem of sealing, but there will be a problem of matching clearance due to relative movement. Therefore, the guide The guidance of the wall between the two drums should be reduced, but the guidance of the local guide structure can be used. For example, a collar structure is provided on the outer wall of the drum with a small diameter to reduce the overall joint surface area, and the guiding effect is relatively good.

As shown in Fig. 3, the second part is fixedly arranged on the mouth of the second inner drum, which is convenient for installation and replacement.

Further, referring to the accompanying drawing 3 of the specification, as a guiding method, a guiding part guiding on the inner surface of the second inner drum is also provided in the second inner drum, and the guiding part is passed through the first part. The terminal is fixedly connected after passing the second part.

The helix angle of the first part is not greater than 80 degrees and not less than 60 degrees, which is much larger than half of the helix angle of the thread. For multi-start threads, the helix angle is generally less than 15 degrees, and the friction angle is also greater than the pressure horn.

It is greater than or equal to 60 degrees. For general materials, the pressure angle is greater than the friction angle. Therefore, the driving force will be relatively weaker and the operation will be smoother.

However, the helix angle should not be too large, otherwise the meaning of using the helix force will be lost. After rigorous testing, the helix angle should not be greater than 80 degrees, otherwise the driving ability will be seriously reduced.

Preferably, the mouth of the rotary rod 5 is provided with a liquid-tight structure connected with the pressure rod 1 to reduce the liquid damping caused by the open structure and improve the transmission efficiency.

Regarding the setting of the reset device, theoretically, it can be set in any link of the transmission link, for example, it can be set between the pressure bar head of the pressure bar 1 and the top cover 2 . Relatively speaking, it is relatively efficient to set the reset directly on the linear motion component, and usually there will be no dead point.

In a preferred embodiment, the reset device is a spring 4, the spring 4 is arranged in the first inner cylinder, and is sleeved on the first part, the spring 4 is not exposed, the aesthetics is relatively good, and it is also For example, the situation that other things may be clamped when the spring 4 is compressed will not occur.

In some embodiments, the transmission mechanism is a planetary gear mechanism, wherein the sun gear of the planetary gear mechanism is coaxially connected with the rotating rod 5 , and the ring gear of the planetary gear mechanism is connected with the wave wheel 7 .

The planetary gear mechanism is a commonly used transmission mechanism in the mechanical field. It has a relatively large transmission ratio and is used in occasions that require a relatively large transmission ratio. It is generally not used in manual drive equipment, and the large transmission ratio also means that the driving end requires more force.

After a long period of testing, it is acceptable to configure a transmission mechanism with a relatively large transmission ratio in this small washing machine, even for girls with relatively little strength.

As mentioned above, the top cover 2 itself can adopt a hollow design, and can also be easily removed to facilitate putting in clothes, etc., and washing powder can be put in together.

In the above structure, the washing powder can be measured with an external measuring tool, but it is relatively cumbersome to use. For this reason, a side hole is opened on the upper side of the casing 9, and the washing machine also includes a liquid washing powder sealed in the side hole. The weighing device 11 is not easy to cause loss of accessories, and is relatively easy to use.

Further, the top cover 2 is a hollow structure, and is connected with the main body of the casing 9 through a lock structure. LOCK was originally a Korean company name, similar to Jeep. The commonly used sealing connection structure of the company is generally called LOCK, so I won't go into details about this structure here.

In some applications, the clutch assembly includes a slide button 12 arranged on the side of the casing 9, a plunger pump driven by the slide button 12, and the plunger cylinder of the plunger pump is connected through a hydraulic oil circuit, wherein the plunger The cylinder is used to drive the clutch stroke of the inner tub 8 .

The portion of the pulsator 7 located right below the inner barrel 8 is provided with an inserting groove, and the inner barrel 8 is moved into or out of the inserting groove through the clutch stroke. The washing and drying work is realized by adjusting the control slide button 12 on the peripheral body. When the slider is at the bottom, the bottom of the pulsator will move to the groove with a deeper groove depth, so that the inner barrel 8 will be stuck, and the pulsator 7 and the inner barrel 8 will be together, and the pulsator 7 and the inner barrel 8 will rotate at the same time , complete the drying work. When the button was on the top, the bottom end of the pulsator would move to the shallower groove. At this moment, the pulsator 7 was separated from the inner tub 8, and only the pulsator 7 could rotate to complete the washing work.
