- a rotating drum 105 having a garment inlet 125 in the front and a water tank 103 containing the rotating drum 105 are inclined in the upward direction from the horizontal direction by an angle ⁇ in the washing machine housing 102. It is arranged.
- the water tank 103 swings up and down and left and right by the rotation of the rotating drum 105 in the washing and dewatering operations. For this reason, the water tank 103 is supported in a vibration-proof manner in the washing machine casing 102 so as to be swingable.
- the washing machine housing 102 and the water tank 103 are connected by a vibration-proof rubber 112 between the housing opening 107 and the water tank opening 114.
- the door body 108 that covers the housing opening 107 so as to be freely opened and closed is configured to abut against the vibration-proof rubber 112 when the door is closed to seal the inside of the water tank 103.
- the rotating drum 105 rotates during operation of the washing machine, and particularly at high speed during dehydration operation. For this reason, an annular gap is provided between the clothing input port 125 and the water tank opening 114.
- the clothes of the laundry 113 move inside the rotary drum 105 during the operation of the washing machine, the clothes may enter the gap and become bitten.

- an annular covering member 111 made of a metal material is provided at the front end of the water tank opening 114 facing the clothing inlet 125 of the rotary drum 105.
- the clothing caught in the gap does not rub against the resin material such as the water tank 103 or the vibration isolating rubber 112. Therefore, it can prevent clothing from being torn. Further, it is possible to prevent the water tank 103 and the vibration isolating rubber 112 from being worn or damaged.
- metal since metal has a high thermal conductivity, the diffusion of frictional heat generated by rubbing with clothing is fast, and the clothing can be prevented from being melted or torn by heat.
- FIG. 10 is a schematic vertical sectional view of an essential part of another conventional washing machine (see, for example, Patent Document 2).

Is preferred. By narrowing the gap opening 7 formed by the gap, it is considered that no small articles fall from the gap opening 7 or the garment 5 is bitten.
- the garment 5 is mainly a thin cloth
- the garment 5 accommodated in the rotating drum 4 may enter the gap opening 7 while moving.
- the rotating drum 4 rotates at a higher speed than in other processes.
- centrifugal force acts on the garment 5 and moves in the vicinity of the gap opening 7 until the garment 5 is stuck to the peripheral wall of the rotating drum 4 especially during the dehydration process.
- the clothes 5 that are present easily enter the outside of the rotating drum 4 from the gap opening 7 by centrifugal force.
- the garment 5 advances, the garment 5 is in a state of being bitten by the gap opening 7, and the rotation of the rotary drum 4 becomes a resistance to rotation, and the rotation becomes unstable.

- the garment 5 that has entered the gap opening 7 can be easily pulled out by the force drawn to the inside of the rotating drum 4 due to the weight of the garment 5 or entanglement with the other garments 5.
- the extended portion 1c is at the upper portion including the uppermost portion of the water tank opening 1a, a downward force due to its own weight is also generated in the clothing 5, and the clothing 5 can be pulled out more easily.
- the inclined portion 28c of the shielding surface 28 is configured in the circumferential region where the extended portion 1c is provided, so that the garment 5 can be pulled out more easily.

Accordingly, it is possible to prevent the user's finger from entering from the expanded portion 1 c of the gap opening 7 and touching the rotating drum 4 or the back side of the water tank 1 with a hand.
- the region ⁇ in which the expansion part 1c is provided is on the side where the garment 5 is lifted by the rotation of the rotary drum 4 in the dehydration process, and the upper part thereof.
- the rotational speed is increased by gradually accelerating until reaching the target rotation speed.
- an inertial force acts on the garment 5 in the direction opposite to the rotation direction.
- a centrifugal force acting outward in the radial direction and a downward force due to its own weight act on the garment 5.
- the direction of the inertial force acting on the garment 5 is the same direction as its own weight at the horizontal position on the region ⁇ side where the garment 5 is lifted from below by the rotating drum 4.
- the direction of these forces is perpendicular to the direction of the centrifugal force, the magnitude of the centrifugal force becomes larger than other positions, and the garment 5 is most likely to enter the gap opening 7.
- the extended portion 1c and the inclined portion 28c in which the gap opening 7 becomes wide are configured on the upper side and the side on which the garment 5 is lifted, the garment 5 is immediately after the position where the garment 5 is most likely to enter. A configuration that facilitates removal is provided. Therefore, even when the garment 5 enters the gap opening 7, it can be easily pulled out before entering the interior.

- the rotating drum 4 is accommodated in the rotating drum 4 from the rotating drum opening 4a that opens horizontally or slightly upward by an annular rotating drum front surface portion 4c having a radial difference from the rotating drum opening 4a. This prevents the garment 5 from being pushed out. However, if the amount of the garment 5 is large, the garment 5 may be pushed out beyond the front surface portion 4c of the rotating drum. In particular, when the user takes out the garment 5 after the operation is stopped, the garment 5 is biased to the lower part of the rotary drum 4, and therefore the garment 5 may overflow from the rotary drum opening 4 a.
- the derivative 29 provided in the lower part can hold the clothes 5 that are likely to overflow, so that the clothes are prevented from falling and the user can easily put the clothes 5 in and out.
- the amount of water for washing in the washing process and the rinsing process is usually poured only to the lower end of the water tank opening 1a. Accordingly, the user can interrupt the washing operation and open the door 3 without overflowing the washing water from the water tank opening 1a.

- the rotation direction of the rotary drum is limited to one direction.
- the first guide surface 29 a and the second guide surface 29 b provided on the derivative 29 guide the garment 5 in the rearward direction of the rotary drum 4, and therefore require a certain length in the circumferential direction.
- the derivative 29 includes a first guide surface 29 a and a second guide surface 29 b provided on both sides of the derivative 29 corresponding to the rotation of the rotary drum 4 in both directions.
- the first guide surface 29a and the second guide surface 29b are arranged so that the clothes 5 moving in the vicinity of the gap opening 7 do not enter the gap opening 7 in the rearward direction of the rotary drum 4, that is, at the back of the rotary drum 4. It guides smoothly in the direction and pushes in so that the clothes 5 may not be damaged.
- the inclination of the first guide surface 29a provided on the side facing the circumferential movement of the garment 5 that is moved by the rotation of the rotary drum 4 in the dehydration step is provided on the side opposite to the first guide surface 29a.
- the second guide surface 29b is formed more gently than the slope. Thereby, the garment 5 is guided more smoothly along the first guide surface 29a in the backward direction, and even if the rotation of the rotary drum 4 rises, it is possible to cope with the problem.
- the derivative 29 is formed such that the convex tip protrudes to the inside from the front end 4b of the rotary drum opening 4a. Thereby, the derivative
- a space 29c is formed in the forward direction of the water tank 1 along the rotation center axis 12 from the rear end of the water tank opening 1a.
- the derivative 29 is disposed so as to cover the gap opening 7. For this reason, when there is no space 29c, the garment 5 slipped between the derivative 29 and the rotating drum 4 is easily pushed into the derivative 29 and enters the gap opening 7 at the front end of the rotating drum opening 4a.
- the garment 5 that has slipped between the derivative 29 and the rotating drum 4 and has reached the gap opening 7 directly passes the gap opening 7. Enter the space 29c. As a result, the clothing 5 can be prevented from entering the gap opening 7.
- the rib 30 provided on the first guide surface 29a lifts the garment 5 moving in the vicinity of the gap opening 7 in front of the space 29c and guides it to the first guide surface 29a. Accordingly, the garment 5 is reliably guided in the rearward direction of the rotary drum 4, and the garment 5 can be prevented from sliding between the derivative 29 and the rotary drum 4 itself.
- the rib 30 is formed to the vicinity of the convex tip of the derivative 29 so that the tip protrudes inward from the front end 4b of the rotary drum opening 4a. Thereby, the garment 5 lifted by the rib 30 is more reliably guided to the first guide surface 29 a, and the garment 5 can be prevented from sliding between the derivative 29 and the rotating drum 4.
- the shielding surface 28 demonstrated what the same thing as the width
- it may be formed to have a width larger than the width of the gap opening 7 as long as space permits.
- a second shielding surface 31 may be provided. By doing so, the garment 5 comes into contact with the second shielding surface 31 and is difficult to enter. Accordingly, the progress of the entry of the garment 5 is further suppressed, and the garment 5 is pushed out more reliably at the inclined portion 28c.
- guide_body 29 demonstrated what was comprised in the lower part of the water tank opening part 1a, it is not restricted to it. For example, by being configured at the top, it becomes difficult for the user to touch when the garment 5 is put in and out. As a result, the clothes can be taken out more easily, and the derivative 29 can be hidden behind the water tank opening 1a and difficult to see, so that the design is improved.
- the washing machine includes the housing 2 and the rotation center shaft 12 inclined in the horizontal or downward direction from the front to the rear of the housing 2, and the front is a rotating drum.
- a rotating drum 4 having an opening 4a, and a water tank 1 that accommodates the rotating drum 4 so as to be rotatable in both directions, and has a water tank opening 1a at a position facing the rotating drum opening 4a along the rotation center axis 12. It has.
- the control unit 14 that executes a washing operation including a washing step, a rinsing step, and a dehydration step, and the front end 4b of the rotating drum opening 4a and the rear end 1b of the water tank opening 1a, and is formed over the entire circumference.
- the gap opening 7 is provided.
- the shielding surface 28 is provided over the entire circumference on the outer peripheral side of the gap opening 7 inside the water tank 1, and the shielding surface 28 is an inclined portion that is inclined at least partially in the circumferential direction toward the inner circumferential side in the circumferential direction. 28c.
- the inclined portion 28c is formed so as to be inclined toward the inner peripheral side along the rotation direction of the rotary drum 4 in the dehydration step.
- the clothing enters the side of the rotating drum from the opening of the gap by the centrifugal force of rotation mainly when the rotational speed of the rotating drum starts to increase in the dehydration process. Accordingly, when the inclined portion is inclined toward the inner peripheral side along the rotation direction of the rotary drum in the dehydrating step, the clothing that has entered the gap opening in the dehydrating step is guided and pushed out to the rear end side of the water tank opening. As a result, the clothing that has entered the gap opening can be easily pulled out.
- the water tank opening 1a is provided with an extended portion 1c that widens the width of the gap opening 7 and the shielding surface 28 in a part of the circumferential direction.
- 28c is comprised in the area
- the inclined portion 28c has a portion formed on the shielding surface 28 of the portion where the extension portion 1c is formed and widened by the extension portion 1c, and this portion is a water tank opening. It extends to the rear end 1b of the part 1a.
- the shielding surface 28 is configured to be inclined outward toward the front side of the water tank 1.
- the clothing that has entered the opening of the gap and has reached the shielding surface further receives a force in the outer peripheral direction due to centrifugal force and moves in the forward direction of the water tank along the inclination to the outside of the shielding surface. Therefore, the clothing that has entered is less likely to enter the outer peripheral side than the shielding surface. Moreover, since clothing moves in the direction away from the rotating drum opening, it can be pulled out more easily.
- the inclined portion 28c is formed in the upper part of the entire circumference of the shielding surface 28.
- the expansion portion 1c is provided on the upper part of the water tank opening 1a.
- the clothing that has entered the gap opening reaches the expansion when it is lifted up. At this time, since the clothing receives a downward force due to its own weight, it can be pulled out more easily. Further, when the user puts in and out the clothes, the extension portion is configured at an upper portion that is relatively difficult for the user to touch. Accordingly, it is possible to prevent the user's finger from entering through the gap by mistake and touching the back side of the rotating drum or the water tank directly.
- the expansion portion 1c is provided on the side where the clothes are lifted by the rotation of the rotary drum 4 in the dehydration step.
- the rotating drum rotates at high speed in the same direction in the dehydration process, it is gradually accelerated until the target rotational speed is reached. During this acceleration, an inertial force acts on the garment in the direction opposite to the rotational direction. Furthermore, the centrifugal force applied in the radial direction and the force due to its own weight act on the clothing.
- the direction of inertial force is in the same direction as its own weight at the horizontal position where the garment is lifted from below by the rotating drum.
- the magnitude of the centrifugal force acting outward in the radial direction is larger than other positions, and the clothing is most likely to enter the gap opening.
- the extended portion where the gap opening is wide is configured on the side where the clothing is lifted, so that a configuration in which the clothing can easily come out immediately after the position where the clothing is most likely to enter is provided. . Therefore, even when the clothing enters the gap opening, it can be easily pulled out by the expansion portion before entering the interior.
- the washing machine according to the present invention makes it difficult for clothes to enter the gap opening between the water tank opening and the rotating drum opening, and even when it enters, the washing machine can easily enter the rotating drum. You can get out. Therefore, it can be applied not only to a washing machine but also to a dryer using a rotating drum.
