Description

The present invention relates to a washing machine capable of eliminating the imbalance of the washing / dehydrating tub while continuing the rotation of the washing / dehydrating tub and suppressing vibration and noise due to the eccentricity of the washing / dehydrating tub during dehydration.

Conventionally, there is a washing machine having baffles arranged at equal intervals in the circumferential direction on the inner peripheral surface of the washing / dehydrating tub (see, for example, Patent Document 1). Each baffle is formed so as to extend in the vertical direction from the bottom of the washing / dehydrating tub to the upper end. An opening is formed at the lower end of the baffle near the bottom of the washing / dehydrating tub, and a circulating water port is formed at the upper end of the baffle. Therefore, in the washing step, the washing water stirred in the lower blade portion of the pulsator infiltrates through the opening, rises inside the baffle, is discharged from the circulating water port, and the clothes are shower-washed.

In a washing machine, the dehydration process is generally performed after the washing process, but if the bias of the laundry is large during dehydration, the eccentricity of the washing / dehydrating tub during rotation becomes large, and a large torque is required for rotation. Therefore, the dehydration operation cannot be started. Therefore, in Patent Document 1, an unbalanced amount and an unbalanced position of clothes in the washing / dehydrating tub are detected at the time of dehydration, and if there is an imbalance, a plurality of baffles evenly provided in the circumferential direction of the washing / dehydrating tub are provided. A technique for positively eliminating the unbalanced state of the washing / dehydrating tub by injecting water into the washing / dehydrating tub is disclosed.

Japanese Unexamined Patent Publication No. 2017-56025

In the washing machine of Patent Document 1, a nozzle unit is arranged above the baffle, and when water is injected into the baffle, the adjusting water injected from the nozzle unit forms a communication member connected to the upper end of the baffle. It is configured to flow into the baffle through. That is, in the washing process, the baffle is used as a circulation passage for washing water for shower washing, whereas in the dehydration process, the baffle is a water storage unit for adjusting water for eliminating the unbalanced state of the washing / dehydrating tank.

In this way, the same space in the baffle is also used as the circulation passage and the water storage section, and at the upper end of the baffle, the internal space is divided into a space communicating with the circulation water port side and a space communicating with the nozzle unit side. is doing.

Therefore, in the washing machine of Patent Document 1, when the baffle is used as a circulation passage for washing water for shower washing in the washing process, the washing water infiltrated from the opening at the lower end of the baffle rises inside the baffle. When the washing water is discharged from the circulating water port, a part of the washing water that has risen inside the baffle enters the space communicating with the nozzle unit side at the upper end of the baffle. Therefore, there is a problem that all the washing water that has been poured up in the baffle cannot be discharged from the circulating water port, and sufficient washing water cannot be discharged from the circulating water port. In addition, since the same space in the baffle doubles as a circulation passage and a water storage part, if the height of the circulation water port at the upper end of the baffle is lowered, washing after dehydration is performed when draining from the baffle at the end of dehydration. There is a risk of getting things wet.

It is preferable to have ribs arranged on the outer peripheral side of the above.

In the washing machine according to the present invention, it is preferable that the water injection portion has a connecting portion connecting the intermediate portions in the height direction of the two first water storage portions.

According to the present invention, a circulation passage for washing water for shower washing in the washing step and a water storage section for adjusting water for eliminating the unbalanced state of the washing / dehydrating tank in the dehydration step are separately provided. Therefore, the unbalanced state of the washing / dehydrating tub can be eliminated by injecting water in the dehydration step, and sufficient washing water can be discharged from the circulating water port of the circulation passage for washing in the shower in the washing step. In addition, the height of the circulation water outlet of the circulation passage can be freely designed.

Hereinafter, the washing machine 1 according to the embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing the appearance of a vertical washing machine (hereinafter referred to as “washing machine”) 1 according to the embodiment of the present invention. FIG. 2 is a schematic view showing the configuration of the washing machine 1 of the present embodiment.

The washing machine 1 of the present embodiment includes a washing machine main body 1a, a washing / dehydrating tub 2, an outer tub 3, a water injection device 30, and a drive unit 50.

The washing machine main body 1a shown in FIG. 1 has a substantially rectangular parallelepiped shape. On the upper surface of the washing machine main body 1a, an opening 11 for putting in and taking out laundry from the washing and dehydrating tub 2 is formed, and an opening / closing lid 11a capable of opening and closing the opening 11 is attached.

The outer tub 3 is a bottomed cylindrical member arranged inside the washing machine main body 1a, and can store washing water inside. A drainage pipe 3n is connected to the bottom surface of the outer tank 3. As shown in FIG. 2, an acceleration sensor 58 capable of detecting acceleration in two directions, horizontal and vertical, is attached to the outer peripheral surface 3a of the outer tank 3. In the present embodiment, the acceleration of the outer tub 3 is detected by the acceleration sensor 58, but the acceleration of the washing / dehydrating tub 2 is assumed to be substantially the same as the acceleration of the outer tub 3.

The washing / dehydrating tub 2 is a bottomed cylindrical member that is arranged coaxially with the outer tub 3 in the outer tub 3 and is rotatably supported. The washing / dehydrating tub 2 can accommodate laundry inside, and has a large number of water passage holes 2t on the inner peripheral surface 2a thereof.

A pulsator (stirring blade) 4 is rotatably arranged in the center of the bottom 2c of the washing / dehydrating tub 2. As shown in FIG. 2, the pulsator 4 includes a substantially disk-shaped pulsator main body 4a, a plurality of upper blade portions 4b formed on the upper surface of the pulsator main body 4a, and a plurality of lower blades formed on the lower surface of the pulsator main body 4a. It has a part 4c. Such a pulsator 4 agitates the washing water stored in the outer tub 3 to generate a water flow.

The drive unit 50 shown in FIG. 2 is driven by the dehydration tank 2 and the pulsator 4 by rotating the pulley 52 and the belt 53 by the motor 51 and rotating the drive shaft 54 extending toward the bottom 2c of the dehydration tank 2. A force is applied to rotate the dehydration tank 2 and the pulsator 4. In the washing machine 1, only the pulsator 4 is mainly rotated in the washing step, and in the dehydration step, the dehydration tub 2 and the pulsator 4 are integrally rotated at high speed. Further, in the vicinity of one of the pulleys 53, a proximity switch 55 capable of detecting the passage of the mark 52a formed on the pulley 52 is provided.

FIG. 3 is a vertical sectional view of the washing / dehydrating tub 2 of the washing machine 1 of the present embodiment. FIG. 4 is a horizontal cross-sectional view of the washing / dehydrating tub ₂ in the line a1 _- a1 of _FIG . 3, and FIG. 5 is a horizontal cross-sectional view of the washing / dehydrating tub ₂ in the line a2-a2 of FIG. FIG. 6 is a horizontal cross-sectional view of the washing / dehydrating tub ₂ in line a3 _- a3 of FIG.

As shown in FIGS. 3 and 4, three baffles 6 are provided on the inner peripheral surface 2a of the washing / dehydrating tub 2 at equal intervals (equal angles) in the circumferential direction. Each baffle 6 extends in the vertical direction from the bottom 2c of the washing / dehydrating tub 2 to the upper end, and is formed so as to project from the inner peripheral surface 2a of the washing / dehydrating tub 2 toward the axis S1. Further, each baffle 6 is hollow and has an arcuate cross-sectional shape.

Each baffle 6 has a circulation passage 8 in which the washing water stirred by the lower blade portion 4c of the pulsator 4 is passed toward the upper end portion of the washing / dehydrating tank 2 and discharged from the circulating water port 8a in the washing step, and the washing is performed in the dehydration step. It has a water injection unit 10 for adjusting water for eliminating the unbalanced state of the dehydration tank 2. In each baffle 6, the circulation passage 8 and the water injection portion 10 are formed as separate spaces.

As shown in FIG. 2, a horizontally long circulation water port 8a is formed at the upper end of such a circulation passage 8. Further, at the lower end of the circulation passage 8, an opening 8c that opens in the vicinity of the bottom 2c of the washing / dehydrating tub 2, more specifically below the pulsator main body 4a, is formed.

Therefore, in the washing step in which the drain valve _3na (see FIG. 2) attached to the drain pipe 3n is closed and the washing water is stored in the outer tub 3, the pulsator is shown by an arrow in FIG. The washing water stirred by the lower blade portion 4c of 4 infiltrates through the opening 8c, rises in the circulation passage 8, is discharged from the circulation water port 8a, and the clothes are shower-washed. Further, by repeating this operation, the washing water circulates in the washing / dehydrating tank 2.

Each of the three water injection units 10 has two first water storage units 11 arranged on both sides of the circulation passage 8 and a second water storage unit 12 connecting the upper ends of the two first water storage units 11. There is. That is, the water injection unit 10 has two first water storage units 11 which are two left and right divided areas, and a second water storage unit 12 which is an integrated area above the two first water storage units 11. The first water storage portion 11 and the circulation passage 8 have substantially the same height, and almost no gap is formed between them.

As shown in FIG. 5, in the three water injection portions 10, comb-shaped ribs 11T are arranged at the boundary between the upper end portion of the first water storage portion 11 and the lower end portion of the second water storage portion 12. The comb-shaped rib 11T is a plate-shaped member that curves along the outer shape of the upper end portion of the washing / dehydrating tub 2. The comb-shaped rib 11T has 10 inlets 11a arranged on the inner peripheral side thereof and 10 ribs 11A arranged on the outer peripheral portion of the inlet 11a. Five inflow ports 11a are arranged on one side of the circulation passage 8 of the comb-shaped rib 11T in the circumferential direction, and five inflow ports 11a are arranged on the other side of the circulation passage 8 in the circumferential direction. .. That is, above the first water storage unit 11, five inflow ports 11a are arranged on both sides of the circulation passage 8.

The water injection device 30 individually injects adjusted water into the three water injection units 10. The water injection device 30 has three water injection hoses 30a connected to each of the three water injection portions 10, and a water supply valve 31a is arranged in each of the water injection hoses 30a. The number of water injection hoses 30a is the same as that of the three water injection portions 10, and they are attached to the upper ends of the three water injection portions 10, respectively.

In this embodiment, tap water is used as the adjusting water. Therefore, when the adjusting water is injected into the second water storage unit 12 by the water injection nozzle 30a of the water injection device 30 while the washing / dehydrating tank 2 is rotating, the adjusted water injected into the second water storage unit 12 is shown in FIG. 7. As shown in the above, after being stored above the comb-shaped rib 11T, it is configured to move from the inflow port 11a formed in the comb-shaped rib 11T into the first water storage unit 11.

A water receiving rib 11b is formed at the lower end of the first water storage portion 11. The water receiving rib 11b projects inward from the outer peripheral surface inside the first water storage portion 11, and a gap is formed between the tip of the water receiving rib 11b and the inner peripheral surface of the first water storage portion 11. .. Therefore, the adjusted water that has moved from the second water storage unit 12 into the first water storage unit 11 while the washing / dehydration tank 2 is rotating in the dehydration step is attached to the outer peripheral side in the first water storage unit 11 by centrifugal force. Attached and held above the water receiving rib 11b.

A drainage pipe 11c is connected to the lower end of the first water storage unit 11. Therefore, when the rotation speed of the washing / dehydrating tub 2 becomes small in the dehydration step, the centrifugal force becomes small, and when the rotation speed of the washing / dehydrating tub 2 is larger than the predetermined rotation speed, the adjusting water held above the water receiving rib 11b Does not stick to the outer peripheral side of the first water storage unit 11, and is drained through the gap between the tip of the water receiving rib 11b and the inner peripheral surface of the first water storage unit 11 and the drainage pipe 11c.

Further, the two first water storage portions 11 arranged on both sides of the circulation passage 8 are connected by the connecting portion 16 at the intermediate portion in the height direction thereof. Therefore, when the water surface height of one of the two first water storage portions 11 becomes higher than that of the connection portion 16, the adjustment water passes through the connection portion 16 and moves to the other first water storage unit 11.

FIG. 8A is a view of the comb-shaped rib 11T arranged at the upper end portion of the first water storage portion 11 as viewed from above, and FIG. 8B is a view taken along the line aa of FIG. 8A. It is a schematic diagram of a partial cross section. In FIG. 8A, the position of the water injection nozzle 30a of the water injection device 30 connected to the upper end of the second water storage unit 12 is shown by a dotted line, but the water injection nozzle 30a of the water injection device 30 is the circulation passage 8. Connected upwards. Therefore, in the comb-shaped rib 11T, the inflow port 11a is not formed in the portion arranged below the water injection nozzle 30a.

The width of the first water storage unit 11 (the width along the radial direction of the washing / dehydrating tank 2), the width of the second water storage unit 12, and the width of the comb-shaped rib 11T are all the same in A1. The width A2 of the inflow port 11a formed at the upper end of the first water storage portion 11 is smaller than A1 because the rib 11A protruding inward in the radial direction is formed on the outer peripheral portion thereof.

Therefore, the adjusted water injected from the water injection nozzle 30a of the water injection device 30 to the second water storage unit 12 is attached to the outer peripheral side of the second water storage unit 12 by centrifugal force, and is above the rib 11A of the comb-shaped rib 11T. Be retained. After that, when the amount of the adjusting water held above the rib 11A increases and the amount of the adjusting water exceeds the height of the rib 11A, the adjusting water flows from the inflow port 11a into the first water storage unit 11. Moving.

That is, while the amount of the regulated water injected into the second water storage unit 12 is equal to or less than a predetermined amount, the adjusted water is stored in the second water storage unit 12 and the adjusted water is injected into the second water storage unit 12. When the amount exceeds a predetermined amount, the adjusted water moves from the second water storage unit 12 into the first water storage unit 11.

In the second water storage unit 12, the thickness of the adjusting water (width along the radial direction of the washing / dehydrating tub 2) held above the rib 11A of the comb-shaped rib 11T is substantially the same over the entire circumferential direction. Therefore, the adjusted water moves to the two first water storage portions 11 arranged on both sides of the circulation passage 8 at almost the same time.

In the washing machine 1 of the present embodiment, when the proximity switch 55 detects the marker 52a (see FIG. 2), the unbalance amount is calculated from the magnitude of the horizontal and vertical acceleration from the acceleration sensor 58, and the acceleration is accelerated. The angle in the unbalanced direction is calculated from the signal indicating the horizontal and vertical acceleration from the sensor 58 and the signal indicating the position of the marker 52a input from the proximity switch 55.

Based on the signal indicating the unbalanced amount and the unbalanced position, it is determined which water injection unit 10 in the washing / dehydrating tub 2 is to be supplied with water, and the water supply amount is determined based on a control program stored in advance. Regarding which water injection unit 10 in the washing / dehydrating tub 2 is to be supplied with water, the water injection unit located in the washing / dehydrating tub 2 at a position facing the position where the lump of laundry, which is a cause of imbalance, is present. 10 is selected. Then, the water supply valve 31a connected to the selected water injection unit 10 is opened to inject the adjusted water, and when the imbalance is resolved by the water injection unit 10, the injection of the adjusted water is stopped.

As described above, the washing machine 1 of the present embodiment is arranged on the washing / dehydrating tub 2 in which the pulsator 4 is arranged at the bottom and the inner peripheral surface 2a of the washing / dehydrating tub 2, and is stirred by the lower blade portion 4c of the pulsator 4.
