Description

Technical Field

[0001] The utility model relates to the technical field of washing machines, in particular to a washing machine that does not require cleaning. Background Art

[0002] In order to solve the water-saving and secondary pollution problems of fully automatic pulsator washing machines, the industry has developed water-saving washing machines, that is, hole-free inner barrel washing machines. For example, the structure of the pulsator washing machine is that the lower part of the inner barrel is designed as an integral whole, and there is only a circle of water-discharging holes in the barrel wall near the balance ring, and there are no holes in other parts. During the washing process, the inner barrel of this structure washing machine contains water, and there is no water between the inner barrel and the box body, which can solve the problems of water saving and secondary pollution. However, the existing inner barrel water switch device has a poor sealing effect and a short service life. The dirty water in the inner barrel must be discharged before dehydration, but it must be closed for rotation during washing and dehydration. How to effectively discharge the water in the inner barrel is a technical problem that we currently need to solve.

[0038] Example 1

[0039] like Figures 1 to 6 As shown, the present application discloses a no-cleaning washing machine, comprising:

[0040] An inner barrel assembly 1, wherein a drainage hole 9 is provided on the inner barrel assembly 1, and a normally closed one-way valve 16 is provided at the drainage hole 9;

[0041] The outer barrel assembly 2 is concentrically sleeved outside the inner barrel assembly 1, and a clutch assembly 6 is arranged outside the center thereof;

[0042] The spiral push plate assembly 14 is concentrically sleeved on the outside of the clutch assembly 6, and includes an inclined push plate fixed plate 1401, an inclined push plate movable plate 1402 and a vertical push plate 1403. The inclined push plate movable plate 1402 is sleeved on the inclined push plate fixed plate 1401 and can be lifted upward relative to the inclined push plate fixed plate 1401 under the action of a force-applying device. The vertical push plate 1403 is arranged above the inclined push plate movable plate 1402 through a plane bearing, and the vertical push plate 1403 moves upward along the axial direction of the clutch assembly 6 to push open the normally closed one-way valve 16 when the inclined push plate movable plate 1402 rotates and lifts upward.

[0043] The wash-free washing machine disclosed in the present application is characterized in that a spiral push plate assembly 14 including an inclined push plate fixed plate 1401, an inclined push plate movable plate 1402 and a vertical push plate 1403 is concentrically sleeved on the outer side of the clutch assembly 6. When the wash-free washing machine is draining water, the inclined push plate movable plate 1402 of the spiral push plate assembly 14 is upwardly rotated and lifted relative to the inclined push plate fixed plate 1401 under the action of a force-applying device (such as a motor, a spring or a gear). As the inclined push plate movable plate 1402 is lifted upward, the vertical push plate 1403 connected to the inclined push plate movable plate 1402 through a plane bearing is 03 will move upward along the axial direction of the clutch assembly 6, the inclined push plate movable plate 1402 and the vertical push plate 1403 are in the upper position, thereby pushing open the normally closed one-way valve 16 set at the drain hole 9 of the inner barrel assembly 1, and water can be smoothly discharged from the inner barrel assembly 1 through the drain hole 9 to the outside, thereby realizing reliable drainage of the no-clean washing machine; under the washing condition, the inclined push plate movable plate 1402 and the vertical push plate 1403 are in the lower position, and the normally closed one-way valve 16 blocks the drain hole 9, thereby preventing the washing water inside the inner barrel assembly 1 from leaking out, avoiding unnecessary waste, and achieving a water-saving effect.

[0044] The no-clean washing machine described in the present application adopts a spiral push plate assembly 14 including an inclined push plate fixed plate 1401, an inclined push plate movable plate 1402 and a vertical push plate 1403 to adjust the opening and closing of the normally closed one-way valve 16 at the drainage hole 9, thereby achieving reliable drainage and water-saving effects. It has a compact structure and precise control, and improves the reliability and stability of the drainage adjustment of the no-clean washing machine.

[0045] As a preferred example of the present application, the inclined push plate movable plate 1402 and the inclined push plate fixed plate 1401 are limited by the matching of the movable plate spiral guide groove 1402a and the fixed plate spiral rib 1401a to realize the lifting of the inclined push plate movable plate 1402 when rotating. In the example of the present application, the fixed plate spiral rib 1401a is provided on the inclined push plate fixed plate 1401, and the movable plate spiral guide groove 1402a is provided on the inclined push plate movable plate 1402. The upper and lower surfaces of the movable plate spiral guide groove 1402a are correspondingly matched and arranged with the fixed plate spiral rib 1401a and can be moved movably. When the inclined push plate movable plate 1402 rotates a certain angle relative to the inclined push plate fixed plate 1401, the inclined push plate movable plate 1402 simultaneously moves axially under the action of the movable plate spiral guide groove 1402a and the fixed plate spiral rib 1401a, thereby realizing the reliable spiral lifting of the inclined push plate movable plate 1402 along the axis. By cooperating with the above-mentioned movable plate spiral guide groove 1402a and fixed plate spiral rib 1401a, the inclined push plate movable plate 1402 can be reliably lifted and lowered in a spiral manner along the axis, ensuring that the inclined push plate movable plate 1402 has a stable motion trajectory during the lifting process, avoiding possible shaking or deviation, achieving precise control of the lifting height, and ensuring the accuracy and reliability of the control of the normally closed one-way valve 16 when the inclined push plate movable plate 1402 lifts and moves.

[0046] As a preferred example of the present application, the vertical push plate 1403 and the inclined push plate fixed plate 1401 realize axial displacement of the vertical push plate 1403 when the inclined push plate movable plate 1402 rotates to lift or lower through the cooperation and limitation of the push plate vertical guide groove 1403d and the fixed plate vertical guide rib 1401d. In the example of the present application, the push plate vertical guide groove 1403d is provided on the vertical push plate 1403, and the fixed plate vertical guide rib 1401d is provided on the inclined push plate fixed plate 1401. The push plate vertical guide groove 1403d and the fixed plate vertical guide rib 1401d are correspondingly and movably matched. When the inclined push plate movable plate 1402 is spirally lifted and lowered, the vertical push plate 1403 is driven to move axially. Due to the limitation of the push plate vertical guide groove 1403d, the vertical push plate 1403 can only move axially. This setting realizes stable axial displacement of the vertical push plate 1403 when it is lifted or lowered with the rotation of the inclined push plate movable plate 1402 through precise guiding and positioning design. It has high precision, strong reliability, and is easy to install and maintain.

[0047] As a preferred example of the present application, a push plate compression spring groove 1403c is provided on the vertical push plate 1403, a small compression spring 1408 is provided in the push plate compression spring groove 1403c, and correspondingly, a gland screw hole 1401e is provided on the inclined push plate fixing plate 1401, a small compression spring gland 1407 is fixed at the gland screw hole 1401e by screws, and the two ends of the small compression spring 1408 are respectively connected to the push plate compression spring groove 1403c and the small compression spring gland 1407. This arrangement enables the vertical push plate 1403 to move downward as a whole when the inclined push plate fixing plate 1401 moves downward, realizing the integrated linkage between the inclined push plate fixing plate 1401 and the vertical push plate 1403, and ensuring the synchronization and coordination between the two. In addition, during the movement of the inclined push plate fixing plate 1401 and the vertical push plate 1403, the small compression spring 1408 can absorb and release part of the impact force and vibration, thereby reducing the impact and noise during the movement and improving the stability and reliability of the system.

[0048] The above arrangement realizes the integrated linkage between the inclined push plate fixing plate 1401 and the vertical push plate 1403 through the buffering and regulating effect of the small compression spring 1408, improves the stability and reliability of the system, simplifies the overall structure, and is easy to install and maintain.

[0049] As a preferred example of the present application, the fixed plate spiral rib 1401a and the movable plate spiral guide groove 1402a are provided in plurality, the fixed plate vertical guide rib 1401d and the push plate vertical guide groove 1403d are provided in plurality, and the push plate compression spring groove 1403c and the gland screw hole 1401e are provided in plurality. In the example of the present application, Figure 4 , Figure 5 , Figure 6 As shown, the inclined push plate fixed plate 1401 includes a fixed plate spiral rib 1401a, a fixed plate inner ring 1401b, a swing arm rod mounting hole 1401c, a fixed plate vertical guide rib 1401d and a gland screw hole 1401e, the inclined push plate movable plate 1402 includes a movable plate spiral guide groove 1402a, a movable plate inner ring 1402b and a movable plate fork groove 1402c, and the vertical push plate 1403 includes a push plate plane 1403a, a push plate inner ring 1403b, a push plate compression spring groove 1403c and a push plate vertical guide groove 1403d. This arrangement can increase the contact area and connection points between the inclined push plate fixed plate 1401 and the inclined push plate movable plate 1402, ensure that the inclined push plate movable plate 1402 moves more smoothly and accurately in the vertical direction, and significantly improve the performance and reliability of the entire system.

[0050] As a preferred example of the present application, a rotating arm rod mounting hole 1401c is provided on the inclined push plate fixed plate 1401, and the force-applying device includes a rotating arm rod 1404, which is movably installed inside the rotating arm rod 1404 through a small water seal 1405 and an oil-containing bearing 1406, and the fork pin of the rotating arm rod 1404 is movably inserted into the movable plate fork groove 1402c of the inclined push plate movable plate 1402. The rotating arm rod 1404 rotates under the action of the force-applying device, and can simultaneously drive the inclined push plate movable plate 1402 to rotate, thereby driving the vertical push plate 1403 to move up and down. When the rotating arm rod 1404 arranged on the inclined push plate fixed plate 1401 rotates a certain angle under the external force of the force-applying device, it can drive the inclined push plate movable plate 1402 to rotate a certain angle, thereby further enhancing the linkage, stability and reliability of the mechanism, realizing precise control, improving the reliability of the rotation control of the inclined push plate movable plate 1402, and simplifying the structure to improve production efficiency.

[0051] As a preferred example of the present application, an inner barrel flange 8 is provided at the bottom of the inner barrel assembly 1, the drainage hole 9 passes through the inner barrel assembly 1 and the inner barrel flange 8, the normally closed one-way valve 16 includes a valve seat 10, a valve spring 11, a valve core rod 12 and a rubber valve plug 13, the valve seat 10 is fixed at the drainage hole 9, the rubber valve plug 13 is sleeved on the valve core rod 12 and can move along the central axis of the valve seat 10, the valve spring 11 is provided between the valve core rod 12 and the valve seat 10 so that the rubber valve plug 13 closes the drainage hole 9 under normal conditions. In the example of the present application, the inner barrel assembly 1 of the wash-free washing machine is a relatively non-porous washing barrel structure, the bottom of the inner barrel assembly 1 is sealed and fixedly connected to the inner barrel flange 8, a structure fixedly connected to the clutch upper shaft sleeve flange is provided in the middle of the inner barrel assembly 1, one or more drainage holes 9 are provided around the central axis of the structure, and a normally closed one-way valve 16 is provided at each of the drainage holes 9. This arrangement ensures that during the operation of the no-clean washing machine, the drain hole 9 can remain tightly sealed when drainage is not required to prevent the washing water from flowing back or leaking; when drainage is required, the drain hole 9 can be quickly opened through simple operation or automatic control system to allow the washing water to be discharged smoothly. The structure is simple and the use is reliable.

[0052] As a preferred example of the present application, the inclined push plate fixing plate 1401 is arranged on the upper surface of the bottom plate of the outer barrel assembly 2, the swing arm rod 1404 passes through the bottom plate of the outer barrel assembly 2 and is connected to the second tractor 7, an outer barrel drain port 3 is arranged on the bottom plate of the outer barrel assembly 2, the outer barrel drain port 3 is communicated with the inlet end of the drain valve 4, the drain valve 4 and the clutch assembly 6 are connected with the first tractor 5, and the first tractor 5 can adjust and control the working state of the drain valve 4 and the clutch assembly 6. The structure of adjusting the working state of the drain valve 4 and the clutch assembly 6 by the first tractor 5 is a prior art and will not be described in detail here.

[0053] The working process of the no-cleaning washing machine described in this application is as follows:

[0054] 1. Water intake and washing process: the first tractor 5 and the second tractor 7 are not working, the machine is in the initial state, the inclined push plate movable plate 1402 and the vertical push plate 1403 are both in the lower position, the normally closed one-way valve 16 at the bottom of the inner barrel assembly 1 is in a closed state, and the washing machine is filled with water. The amount of water inflow to the washing machine can be sensed by a flow meter or a photoelectric sensor, which is not discussed as a technical point here. When the amount of water inflow to the washing machine reaches the set amount of water, it enters the washing state;

[0055] 2. Drainage process: When the washing cycle is over, the first tractor 5 and the second tractor 7 are operated simultaneously. The first tractor 5 is operated to make the washing machine in the state where the drain valve 4 is drained and the clutch assembly 6 is dehydrated (the motor is not rotating and not working). The second tractor 7 is operated to rotate the arm rod 1404 to make the inclined push plate movable plate 1402 spirally rise, and then the vertical push plate 1403 is axially raised. The push plate plane of the vertical push plate 1403 moves upward to push the valve core rod 12 at the bottom of the inner barrel assembly 1 to move upward, so that the rubber valve plug 13 at the drain hole 9 is opened, and the washing water in the inner barrel assembly 1 is discharged between the inner and outer barrels, and then discharged through the drain valve 4. The end of drainage can be sensed by the light sensor;

[0056] 3. Dehydration process: After the drainage is completed, the first tractor 5 is still in working state, while the second tractor 7 stops working. Under the action of each reset spring, the arm rod 1404 returns to the initial state, the inclined push plate movable plate 1402 and the vertical push plate 1403 both fall back to the low position of the initial state, and the valve plug rod at the bottom of the inner barrel assembly 1 is separated, and the normally closed check valve 16 returns to the closed state. At this time, the amount of water in the inner barrel assembly 1 is small, and during high-speed dehydration, it is discharged between the inner and outer barrels through the water-throwing holes set on the inner barrel wall on the lower side of the balance ring, and then discharged from the drainage valve 4.

[0057] In the example of the present application, the hole-free inner barrel refers to an inner barrel assembly without a flow hole for washing water exchange between the inner and outer barrels under washing conditions, and the drainage hole 9 on the inner barrel assembly 1 is closed under normal conditions and can be opened under drainage conditions. Preferably, the wash-free washing machine of the present application is a pulsator washing machine.

[0058] Example 2

[0059] like Figures 1 to 8 As shown, the wash-free washing machine disclosed in the present application discloses the structure of a second spiral push plate assembly, and a swing arm gear 1409 is arranged on the outer circumference of the inclined push plate movable plate 1402, and correspondingly, a transition gear 17 is arranged on the swing arm rod 1404, and the transition gear 17 is meshed and matched with the swing arm gear 1409. When the swing arm rod 1404 rotates under the action of the second traction device 7, the inclined push plate movable plate 1402 is driven to rotate through the transition gear, and other structures are the same as those in Example 1.

[0060] This setting adopts the meshing mode of the swing arm gear 1409 and the transition gear 17, which realizes the direct driving of the swing arm rod 1404 on the inclined push plate movable plate 1402, simplifies the transmission structure, makes the rotation of the inclined push plate movable plate 1402 more stable, reduces the vibration and noise during movement, and at the same time makes the inclined push plate movable plate 1402 have a self-locking function when rotating, thereby improving the overall working performance of the washing machine.

The two ends of the steel cable sleeve 1504 are respectively fixed with a front fixing seat 1503 and a rear fixing seat 1505, and the front fixing seat 1503 is fixed on the inclined push plate fixing plate 1401. The steel cable 1501 and the steel cable sleeve 1504 pass through the bottom of the outer barrel assembly 2 and are fixed to the outer side of the bottom of the outer barrel assembly 2 through the rear fixing seat 1505. In the example of the present application, when the second tractor 7 pulls the tractor connection structure 1508 and the buffer spring 1507 and the steel cable 1501 and other parts, they are moved along the axis of the steel cable sleeve 1504, and then the inclined push plate movable plate 1402 is pulled to rotate a certain angle.

[0063] Compared with the first embodiment, the swing arm 1404 is cancelled, and the steel cable assembly 15 is used to pull the inclined push plate movable plate 1402 to rotate and lift relative to the inclined push plate fixed plate 1401. The specific structure of the steel cable assembly 15 disclosed above is mainly composed of a steel cable 1501 and a steel cable sleeve 1504, wherein the steel cable sleeve can flexibly move on the steel cable. The two ends of the steel cable are respectively equipped with a front end head 1502 and a rear end head 1506, which ensures the stable connection and reliable traction of the steel cable 1501. The front end head 1502 is fixed on the inclined push plate movable plate 1402, so that the steel cable assembly 15 can directly act on the inclined lifting mechanism, thereby realizing effective inclined adjustment or control; and the fixing of the rear end head 1506 and the buffer spring 1507 provides a good buffering effect, reducing the impact and damage to the inclined mechanism caused by the instability or sudden stop of the external second tractor 7. The design of the above-mentioned steel cable assembly 15 ensures the stability of the steel cable during activities. It also enhances the structural strength and stability of the entire system by passing through the bottom of the outer barrel assembly and fixing it on the outside. It can meet the needs of various application scenarios and provide a reliable solution for the adjustment and control of the inclined jacking mechanism.

[0064] The second tractor 7 pulls the tractor connection structure 1508 to achieve the same effect as the rotating arm 1404 in embodiment 1.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
