Detailed ways

The embodiments of the present invention will be clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is not intended to limit the scope of the invention.

Embodiment 1

As shown in FIGS. 1-6, a washing machine includes a washing machine housing 100, an inner tub 200 disposed in the washing machine housing 100, and a driving device 300 for driving the inner tub 200 to rotate. The inner tub 200 is a water tub. The utility model further comprises a shock absorbing structure and a water collecting structure, wherein the water collecting structure is installed in the washing machine housing 100 through the shock absorbing structure, and the water collecting structure is located outside the inner tub.

At the time of dehydration and/or drainage, the water discharged from the inner tub 200 is discharged through the water collecting structure.

By setting the water collecting structure, when washing/rinsing, the inner tub 200 is a water tub, and when the water is dehydrated and/or drained, the water collecting structure collects the water discharged from the inner tub 200, such a cooperation eliminates the outer tub, in the washing machine. In the case where the volume of the casing 100 is constant, the available space of the inner tub 200 in the washing machine housing 100 is increased, and the purpose of expanding the inner tub 200 can be achieved by increasing the diameter of the inner tub 200.

By the shock absorbing effect of the shock absorbing structure, the vibration of the inner tub 200 and the water collecting structure is reduced, the inner tub 200 and the water collecting structure are prevented from colliding with the washing machine housing 100, and the inner tub 200, the water collecting structure and the washing machine housing 100 are damaged. .

Further, the water collecting structure includes a water collecting chamber 400 having an upper opening, and an output shaft 303 of the driving device 300 is connected to the inner tub 200 through the water collecting chamber 400, and an upper opening of the water collecting chamber is lower than an inner tub The inner barrel is set.

Further, the inner tub 200 is disposed in the water collecting chamber 400, and the output shaft 303 of the driving device 300 is connected to the inner tub 200 through the bottom wall of the water collecting chamber 400 to drive the inner tub 200 to rotate, and the output shaft 303 and the water collecting chamber can pass through the bearing. Sealed connection.

In the current washing machine, an outer tub is generally disposed outside the inner tub 200, and the outer tub is a water tub. During the washing process, the output shaft 303 of the driving device 300 rotates to drive the inner tub 200 to rotate. When the inner tub 200 reaches the resonance point, it is easy to cause the inner tub. The strong shaking of 200 easily causes the inner tub 200 to collide with the outer tub. Therefore, a safe distance is set between the inner tub and the outer tub, which limits the volume of the inner tub, and the collision between the inner tub and the outer tub mainly occurs. Occurrence occurs in the inner barrel mouth portion of the inner tub 200, and substantially no collision occurs in the lower portion.

Based on the above considerations, the present invention does not have an outer tub outside the inner tub 200, which eliminates the space for installing the outer tub and the safety distance between the inner tub and the outer tub, and only needs to consider the safety distance between the inner tub and the washing machine casing. By setting the edge of the upper opening to be higher than the bottom wall of the inner tub 200 and not higher than the water collecting structure of the inner tub mouth, the upper edge of the water collecting structure is lower than the inner barrel mouth, so that the most likely collision position (inner barrel mouth) The space in the vicinity is increased, so that the inner tub mouth does not easily collide with the washing machine casing, and the purpose of expanding the capacity of the inner tub 200 is appropriately achieved.

Further, the water collecting structure includes a mounting plate 500 and a water retaining rib 501 disposed on the mounting plate 500. The mounting plate 500 is enclosed with the water retaining rib 501 to form the water collecting chamber 400. The upper edge of the rib 501 is not higher than the inner barrel opening of the inner tub 200. Preferably, the upper edge of the water retaining rib 501 is not higher than half of the height of the inner tub 200. The mounting plate 500 is enclosed with the water retaining ribs 501 to form the water collecting chamber 400. The structure is simple and convenient for processing and forming.

When the rotational speed of the inner tub 200 approaches the resonance point, the shock absorber is connected to the water collecting structure, so that the inner bucket 200 is more swayed toward the opening, and the inner tub 200 is enlarged, and the water content of the inner tub 200 is increased, so as to save the washing time. The faster the drainage speed, the better. By setting the upper edge of the water retaining rib 501 to no more than half of the inner tub 200, when the washing water flows into the water collecting chamber at a relatively high speed, the water holding capacity is higher due to the water retaining rib 501. Large, the washing water does not overflow due to rapid discharge, effectively preventing the washing water from overflowing from the water collecting structure to the electrical components at the bottom of the washing machine housing 100, thereby reducing the possibility of damage of electrical components (such as power boards, etc.). The water retaining rib 501 is disposed on the upper plate surface of the mounting plate 500, and the water collecting chamber is located at the middle of the mounting plate 500, so that the center of gravity of the water collecting device is more easily coincident with the center to reduce the offset.

Further, the inner tub is further provided with a water collecting passage communicating with the inner tub, and the collecting channel is connected with the water collecting chamber; when the washing machine is dehydrated, the water that is pumped out enters the water collecting chamber through the collecting channel, and It is discharged through the water collecting structure.

There are a plurality of dehydration ports 201 and dehydration channels 202, each dehydration port 201 is corresponding to a corresponding dehydration channel 202, or a plurality of dehydration ports 201 may correspond to one dehydration channel 202, when the washing machine performs a spin-drying procedure, due to the inner tub 200 The water that has been extracted by centrifugation enters the dewatering channel 202 through the dehydration port 201, and is discharged into the water collecting chamber 400 through the water outlet 203 of the dehydrating water channel 202, blocking the overflow of the water.

The water outlet 203 of the dewatering channel 202 is disposed in the water collection chamber 400. The water outlet 203 is connected to the water collecting structure. When the water is dried, the water enters the dewatering channel 202 through the dehydration port 201 and is discharged into the water collecting chamber 400 through the water outlet 203 to block the water from overflowing. The water outlet 203 is disposed in the water collecting chamber 400. The water discharged from the water outlet 203 directly falls into the water collecting chamber 400, and the structure is simpler, and it is not necessary to add other additional components, and the water collecting effect is better.

The washing machine can be a pulsator washing machine.

The occlusion device 205 includes a valve plug 205-1 and an electromagnetic device 205-2 disposed under the valve plug 205-1. The electromagnetic device 205-2 is electrically connected to a control device of the washing machine. When the washing machine is in a laundry state, the valve plug 205 -1 sealing the drain port 204 to prevent water from draining in the inner tub 200. When the washing machine is in a drained or dehydrated state, the electromagnetic device 205-2 controls the valve plug 205-1 to move downward, so that the drain port 204 is opened, and the laundry is to be washed. Water is discharged into the catchment structure.

When the washing machine vibrates, the boom 602 assembly can function to reduce the vibration of the inner tub and the washing machine.

The shock absorbing device 3 disposed on the suspension damper of the present embodiment is located between the mounting portion and the damper sleeve 2, covering the upper end surface of the damper sleeve 2, compared with the existing damper cushion. The contact area with the damper sleeve 2 and the mounting portion is increased, and therefore, when the washing machine vibrates and the suspension damper moves up, down, left, and right, there is a flexible material covering between the mounting portion of the water collecting structure and the damper sleeve 2 The area is increased, and the pressure and vibration generated by the collision and vibration between the two are reduced, and the shock absorption effect is good, which can help reduce the vibration of the washing machine.

The support effect is better.

When the support damper 800 and the suspension damper 600 are simultaneously disposed in the washing machine, when the water collecting structure and the inner tub 200 are vibrated, a better shock absorbing effect is achieved by the combined action of the two.

Preferably, the end of the supporting damper member 800 connected to the water collecting structure is located on the bottom wall of the water collecting structure, that is, the lower portion of the mounting plate, and the arrangement is particularly suitable for simultaneously providing the suspension damper 600 and the support. The structure of the shock absorbing member 800, this arrangement disperses the mounting portion and reduces the damage of the water collecting structure. The supporting damper members are disposed at a lower portion of the mounting plate and are evenly distributed in the circumferential direction of the driving device to spread the force points.

Since the inner tub 200 is severely shaken in the horizontal direction when the rotation speed of the inner tub 200 is reduced to a certain range (generally lowered to the vicinity of the resonance point) during the washing process, it is easy to cause the inner tub to collide with the washing machine casing, resulting in the inner tub 200 and/or Damage to the washing machine housing 100. However, both the support shock absorber and the suspension shock absorber are tilted, limited by the set angle, and the vibration in the main vertical direction is relatively poor, and the shock absorption effect in the horizontal direction is relatively poor, in order to reduce the inner tub 200 In the horizontal direction, the present invention provides a horizontal shock absorbing member 11 to reduce the anti-biasing ability of the inner tub 200 and the driving device 300 during the washing process, in particular, to reduce the vibration when the rotating speed of the washing machine reaches the resonance point, and reduce the inner tub 200.

The mechanism moves to achieve a better level of shock absorption.

Further, the horizontal shock absorbing member 11 is movably connected to the water collecting structure and/or to the washing machine housing 100. Since the inner tub 200 and the water collecting structure generate a combined vibration in the longitudinal direction and the horizontal direction during the washing process, a torsional force is generated. By tying the horizontal damper 11 to the water collecting structure and/or to the washing machine housing 100, the torsion of the water absorbing member 11 to the water collecting structure and the washing machine housing 100 is overcome, and the inner tub 200, the water collecting structure and the washing machine are reduced. Damage to the housing 100. Further, the first damper connector 12 and the second damper connector 13 are rotatably coupled to the outer wall of the water collection chamber 400 and the inner wall of the washing machine housing 100, respectively. By connecting the rotating connection, the connecting part absorbs the torsional force and reduces the damage of each component.

Further, the first damper connector 12 is hinged to the outer wall of the water retaining rib 501, and the second damper connector 13 is hinged to the inner wall of the washing machine housing 100.

Since the water collecting chamber 400 is a cavity structure, the first shock absorbing member 12 and the second shock absorbing connecting member 13 are respectively connected to the water retaining rib 501 and the inner wall of the washing machine housing 100, and on the one hand, the horizontal shock absorbing member 11 is reduced. During the small washing process, the inner tub 200 and the water collecting structure collide with the washing machine housing 100, and the anti-biasing ability of the inner tub 200 and the water collecting structure is enhanced. On the other hand, the water retaining rib strength is large, and the first shock absorbing connecting member 12 is blocked. The outer wall of the rib 501 is hinged and is not easily damaged.

The suspension damping member 600, the supporting damping member 800 and the horizontal damping member 11 are all connected with the water collecting structure, and each of the damping members is evenly distributed around the water collecting structure, so that the force received by the water collecting structure is more balanced. When the shock absorbing structure includes at least two of the suspension damper 600, the support damper 800, and the horizontal damper 11, the different types of dampers are interleaved while satisfying the uniform distribution of each damper.

Since the drainage channel 401 is in the normally-on state and the drainage channel is entirely below the water inlet end of the drainage channel, when the water in the inner tub enters the water collecting structure, the water is directly discharged from the drainage channel 401 because the drainage channel is in the normally-on state. Further, the drain channel 401 is in direct communication with the bottom wall of the water collecting chamber 400, and maintaining the normally-on state enables all the water in the water collecting chamber 400 to be discharged without remaining, and does not affect the performance of the water collecting chamber 400. The normal state allows water to be discharged from time to time.

Further, the height of the drainage channel 401 gradually decreases from the water inlet end to the water outlet end, so that the position where the water flow changes direction is reduced, and the potential energy is gradually decreased, so that the water discharge is smoother.

In the second embodiment, the drainage structure includes a drainage channel 401, a control mechanism 802 for controlling the conduction/closing of the drainage structure, the control mechanism 802 is disposed on the drainage channel 401 and communicates with the drainage channel 401, and the washing machine includes the main control device 900. The control mechanism 802 is electrically connected to the main control device 900, and controls the opening/closing of the control mechanism 802 to turn on/off the drain channel 401.

When the washing machine is drained/dehydrated, the control mechanism 802 is in an open state, the drain passage 401 is in an on state, and the water in the water collecting structure can be discharged from the drain passage 401 from time to time under the action of gravity;

Embodiment 5

As shown in FIG. 5 to FIG. 6, the washing machine of this embodiment further includes a detected end and a detecting end for detecting the position of the detected end, and the detected end and the detecting are performed on the basis of the first embodiment to the fourth embodiment. The end is respectively disposed on the inner tub 200 and the washing machine housing 100. The detecting end is electrically connected to the main control device, the detecting end detects the distance between the detected end and the detecting end, and the control device controls the washing machine according to the detection result of the detecting end.

During dehydration, the inner tub rotates to discharge the water in the inner tub through the dehydration port 201. When the rotation speed of the inner tub is near the resonance point, the inner tub 200 easily collides with the washing machine housing 100. If a collision occurs, the inner tub is in a high-speed rotation state. The impact force generated is large, and it is easy to cause damage or even damage to the inner tub and/or the washing machine casing.

The detecting end detects the position of the detected end by respectively providing the detecting end and the detected end on the washing machine casing and the inner tub. When the inner tub is close to the washing machine casing and exceeds the safe distance, the detecting end detects that the detected end is away from the detecting end. Recently, the detection signal is transmitted to the main control device. The safety distance is that if the distance between the inner tub and the washing machine housing is less than or equal to the safe distance, the bucket is hit, and measures are taken to prevent the bucket from being hit. If the distance between the inner tub and the washing machine housing is greater than the safe distance, Then it will not hit the barrel and the washing machine will run normally.

Solution 1: The detecting end can detect the position of the detected end from time to time, and transmit the detection signal to the main control device 900. The main control device 900 determines whether the distance between the detected end and the detecting end is less than a preset value (safe distance), if If the preset value is less than or equal to the limit, the inner tub 200 may hit the bucket, and the main control device 900 controls the washing machine to perform corresponding operations.

For example, the detecting end is an infrared receiving end, the detected end is an infrared transmitting end, the distance is measured by infrared rays, and the detection signal is transmitted to the main control device 900, and the main control device 900 calculates the distance between the inner tub 200 and the washing machine housing 100. A, when A is less than or equal to the preset value, it indicates that the inner tub 200 may collide with the washing machine housing 100, then control the washing machine to pause or stop or decelerate or control the alarm device to issue an alarm.

Solution 2: When the detected end is too close to the detecting end, the detecting end detects the detected end and transmits the signal to the main control device 900. When the distance between the detecting end and the detected end is large, the detecting end cannot detect the detected end. When the detecting end and the detected end are smaller than the safe distance, the detecting end can detect the detected end. At this time, the inner barrel The 200 may collide with the washing machine housing 100, and the detecting end will detect that the signal of the detected end is transmitted to the main control device 900, and the main control device 900 controls the washing machine to perform the corresponding operation.

On the basis of the second embodiment, the detected end is a magnetic member 901 capable of generating a magnetic field, and the detecting end is a magnetic sensing element 903. When the magnetic member 901 is close to the magnetic sensing element 903 and triggers the magnetic sensing element 903 to operate, the magnetic The sensitive element 903 transmits a detection signal to the main control device 900.

The magnetic sensing element 903 is an element that can be triggered under a certain magnetic field force, and can be a magnetically sensitive switch.

Since the magnetic member 901 and the magnetic sensing element 903 are respectively disposed on the inner tub 200 and the washing machine housing 100, when the inner tub 200 is far away from the washing machine housing 100, the magnetic member 901 is also far away from the magnetic sensing member 903, and the magnetic sensing member 903 is far away. It is not affected by the magnetic force or the magnetic force is small, and the magnetosensitive element 903 cannot be triggered to act. When the distance between the inner tub 200 and the washing machine housing 100 is less than the safe distance, the magnetic sensing element 903 acts under the magnetic force of the magnetic member 901 to trigger the magnetic Sensitive element 903 transmits a signal to main control device 900, which controls the washing machine action.

The magnetic member 901 is a magnet 902, the magnet 902 may be a permanent magnet 902 or an electromagnet 902, the magnetic sensing element 903 is a magnetic sensitive switch, and the magnetic sensitive switch may be a reed switch 904. When the electromagnet 902 is used, The electromagnet 902 power source may be a dry battery, such as an electromagnet 902 with a battery, or a power supply device of the washing machine.

Since the magnet 902 and the reed switch 904 are respectively disposed on the inner tub 200 and the washing machine housing 100, when the inner tub 200 is far from the washing machine housing 100, the magnet 902 is also far from the reed switch 904, and the reed switch 904 is not The magnetic force or the magnetic force received is small, and the two reeds of the reed switch 904 cannot be triggered to be magnetized and attracted by the magnetic force. When the inner tub 200 is less than the safe distance from the washing machine housing 100, the reed switch 904 is The magnetic force of the magnet 902 is sucked, the circuit between the reed switch 904 and the main control device 900 is energized, and the main control device 900 receives a signal to control the operation of the washing machine.

Further, a fixing member 905 is disposed on the outer wall of the inner tub 200 or the inner wall of the washing machine housing 100, and the fixing member 905 is fixedly connected with the inner tub 200 or the washing machine housing 100 to form a closed chamber, and the magnetic member 901 Located in the enclosed chamber, the magnetic member 901 is fixed to the inner tub 200 or the washing machine housing 100.

Further, the magnetic member 901 is in surface contact with the closed chamber wall.

The above structure is particularly suitable for arranging the magnetic member 901 on the inner tub 200. Since the inner tub 200 is basically in a rotating state during the washing process, if the inner tub 200 is rotated or vibrated, the inner tub 200 is very rotated or vibrated. It is easy to loosen or drop the plug-in part or the screw-in part, causing serious problems such as a card machine. By placing the magnetic member 901 in the closed chamber, the magnetic member 901 is in surface contact with the closed chamber, and the force is uniform and not easily damaged. , more secure.

Further, the fixing member 905 is a fixing plate, and a central portion of the fixing plate is recessed in a direction away from the inner tub 200 to form a cavity 906. The magnetic member 901 is located in the cavity 906, and the fixing member 905 is fixedly connected with the inner tub 200. The open position of the cavity 906 is closed to form a closed chamber, and the magnetic member 901 is housed in the cavity 906.

By disposing the cavity 906 on the fixing member 905, on the one hand, the manufacturing process is simple and the cost is lower. On the other hand, the direct installation on the existing inner tub 200 can be realized without modifying the structure of the inner tub 200, and the operation is simple and convenient. On the other hand, it is not necessary to slot the inner tub 200, and the strength of the inner tub 200 is not lowered.

The recess 906 may also be formed by partially recessing the outer wall of the inner tub 200. The fixing member 905 is plate-shapedly covered on the cavity and fixedly connected with the inner tub. Although the structure needs to be improved on the inner tub 200, the inner tub 200 is not occupied. The space between the housing 100 and the washing machine housing 100 does not affect the increase of the diameter of the inner tub 200, and does not affect the expansion of the washing machine. Of course, the recess 906 may be simultaneously disposed on the outer wall of the fixing member 905 and the inner tub 200. The cavity 906 is closed to form a closed chamber.

Further, the closed chamber formed by the sealing member 905 and the inner tub 200 is sealingly connected to form a sealed chamber, and the magnetic member 901 is sealed in the sealed chamber.

Since the inner tub 200 is inevitably contaminated with water during the washing process, water may penetrate into the closed chamber. If it is the permanent magnet 902, the interference is relatively small, but if the magnetic member 901 is the electromagnet 902, the closed chamber is not Sealing the chamber may cause damage to the electromagnet 902, causing the magnet to disappear, so it is necessary to seal the chamber.

Further, the connecting portion of the fixing member 905 and the inner tub 200 is provided with a gasket for better sealing. The fixing member 905 is detachably connected to the inner tub 200, and may be a screw connection or a snap connection.

Further, an inner wall of the washing machine housing 100 or an outer wall of the inner tub 200 is provided with a mounting seat 907 for mounting the magnetic sensing element 903, and the mounting base 907 is electrically connected to the main control device 900, and the magnetic sensing element The 903 is mounted on the mount 907 to energize the magnetic sensor 903 and the main control unit 900.

Since the magnetosensitive element 903 is easily damaged and lost during collision, the magnetosensitive element 903 is mounted on the mount 907 by providing the mount 907, and on the one hand, plays a fixed role to make good contact with the main control device 900. The electrical connection relationship reduces the phenomenon of bare and water short circuit, and on the other hand, protects the magnetic sensing element 903 from being damaged.

Further, the mounting seat 907 is provided with an anti-collision portion for preventing the inner tub 200 from colliding with the washing machine housing 100 to damage the magnetic sensing element 903. By providing an anti-collision portion on the mounting base 907, the magnetic sensing element 903 is improved. Safety and increase its service life.

Specifically, the mount 907 is disposed on the inner wall of the washing machine housing and protrudes from the inner wall of the washing machine housing 100. The outer edge of the mount 907 is larger than the outer circumference of the magnetosensitive element 903, and is magnetically sensitive. The component 903 is completely wrapped in the mount 907. This structure is the simplest and the best.

Further, the anti-collision portion partially protrudes outwardly from the inner wall of the washing machine housing 100 to form a boss 908. The outer edge of the boss 908 is larger than the outer circumference of the magnetosensitive element 903. When the inner tub 200 hits the washing machine housing 100, Due to the supporting action of the boss 908, it is impossible to contact the magnetosensitive element 903, thereby achieving the function of protecting the magnetosensitive element 903.

The magnetic sensing element 903 can be mounted on the upper portion of the boss 908 for easy installation and replacement, or can be mounted on the lower portion of the boss 908. Since the upper portion of the inner barrel first contacts the boss, the structure can make the volume of the boss 908 relatively small. Does not affect the expansion of the inner tub 200.

The mounting seat 907 can also be a recess disposed on the inner wall of the washing machine housing 100. The side wall of the recess forms an anti-collision portion to protect the magnetic sensing element 903, and the magnetic sensing element 903 is inserted into the recess. The opening of the groove is small or inclined upward.

Further, the detected end and the detecting end are disposed opposite to the upper portion of the inner tub 200 and the washing machine housing 100, and both surround the inner tub 200. Since the bumper barrel generated during the rotation of the inner tub 200 may occur in various orientations, in order to achieve a better anti-collision barrel effect, both the detected end and the detecting end are set to one week, and the collision bucket in each direction may be detected.

Specifically, in the first embodiment, the detected end is a permanent magnet 902, and the permanent magnet 902 is annular, forming a magnetic ring.

Alternatively, a plurality of permanent magnets 902 are spaced apart from the outer wall of the inner tub 200 and surround the inner tub 200. The permanent magnets 902 are evenly distributed. The washing machine housing 100 is provided with a plurality of reed switches 904, and a plurality of reed switches 904 are connected to each other. One turn, each reed switch 904 is electrically coupled to the main control unit 900 for monitoring.

The permanent magnet 902 is preferably disposed at the upper end of the side wall of the inner tub 200. If the upper portion of the inner tub 200 is provided with a balance ring, the permanent magnet 902 may be disposed on the balance ring. Since the balance ring is the upper portion of the inner tub 200, it is a portion that is more easily impacted.

The main control device 900 determines whether the inner tub collides with the washing machine casing or whether there is a collision with the washing machine casing according to whether the reed switch is conducting or not. Probably, if it is, the actuator is controlled to operate, and if not, the washing machine continues to operate normally.

Specifically, if the reed switch is turned on, the distance between the inner tub and the washing machine housing is less than or equal to the safety distance, and the bucket has been hit or there is a collision barrel. The main control device controls the action of the actuator to prevent the inner tub 200 from colliding. The washing machine housing 100, if not, the distance between the inner tub and the washing machine housing is greater than the safety distance, and the washing machine operates normally.

Different types or types of washing machines have different safety distances. By selecting different magnets with different magnetic strengths and reeds with different resilience magnetization, it is possible to adjust the retraction and separation of the reeds to the corresponding washing machine. Match.

Wherein, the actuator is an alarm or a driving device 300 that drives the inner tub 200 to rotate.

For example, when the two reeds of the reed switch 904 are sucked, the circuit connecting the reed switch 904 to the main control device 900 is turned on, and the signal that the inner tub 200 is too close to the washing machine housing 100 is transmitted to the main control device 900. The control device 900 controls the alarm alarm or controls the motor 301 to stop rotating.
