washing machine

technical field

The present invention relates to a washing machine provided with double-openable doors.

Background technique

As a conventional washing machine, a washing machine whose doors can be double-opened for convenience in use has been proposed (for example, refer to Patent Documents 1 and 2). The double-opening mechanism is configured such that when closing, the left and right ends of the door are held on the main body of the washing machine by the shaft and the bearing, and at the initial stage of the door opening operation, the shaft center is formed between the shaft and the bearing on either side of the door. And the other shaft is separated from the bearing to allow the door to rotate.

In this document, the structure of moving the shaft to the shaft hole provided in the bearing part at the beginning of the opening action is adopted to realize such an action, or the entire door is moved laterally in either direction to the left or right relative to the main body of the washing machine so that the shaft The structure retracts from the bearing part.

Patent Document 2: Japanese Patent Laid-Open No. 2001-159268

Furthermore, unlike refrigerators and the like, a front-loading washing machine requires a latch mechanism for securely keeping the door closed after loading laundry and a lock mechanism for ensuring water-tightness during washing operation.

In the case of a single-opening washing machine, the latching state can be realized by adopting a structure in which claws protruding rearward from the door elastically engage with hooks of the main body of the washing machine in the latch mechanism. In addition, the locked state can be realized by adopting a structure in which a lock pin protruding rearward from the door is accommodated in a lock pin insertion hole provided in the main body of the washing machine and electromagnetically locked as the lock mechanism.

However, when a structure is adopted in which the door does not simply rotate but moves laterally at the initial stage of the opening operation in order to realize a double-opening door, the movement locus of the latch claw changes due to the lateral movement of the door. Therefore, it may happen that the latch claw cannot be disengaged from the hook of the washing machine main body. On the contrary, during the closing operation of closing the door, it may happen that the latch claw cannot be engaged with the hook of the washing machine main body.

In addition, in a double-leaf door, when the door does not simply rotate but moves laterally at the beginning of the opening operation, the following situation may occur before the locking pin of the locking mechanism is pulled out from the locking pin insertion hole in the main body of the washing machine. The locking pin can interfere, preventing the door from opening. On the contrary, during the closing action of closing the door, the locking claw may not be accommodated due to inconsistency with the locking pin insertion hole of the washing machine main body.

Detailed ways

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

FIG. 1 is a perspective view showing a washing machine 1 according to one embodiment of the present invention. In order to understand the double-opening function, FIG. 1 shows two states of the door 2, right-opening and left-opening. FIG. 2 is a diagram showing the relationship between the bottom surface of the door 2 and the washing machine main body 3 in a state where the door 2 is opened. 3 is an enlarged view of the bottom surface of the door 2, including: a pivoting mechanism 4 for supporting the door 2 on the washing machine body 3; 4 is a bottom view showing states of the inner pivoting mechanism 4(in) on the fixed side of the door 2 and the outer pivoting mechanism 4(out) on the anti-fixed side when the door 2 is opened leftward.

As shown in FIGS. 1 and 2 , a washing machine 1 according to this embodiment is a drum type, and left and right ends of a door 2 are respectively attached to a washing machine main body 3 via pivoting mechanisms 4 . And, when performing the opening operation using the handles 21 provided at both left and right ends of the door 2, the door 1 is moved laterally in a sliding motion by the lateral movement mechanism 5 provided between the door 2 and the main body 3 of the washing machine. One of the left and

right pivoting mechanisms

4, 4 is suspended while the other is free, thereby realizing the double-opening action of the door 21.

As shown in FIG. 3 , the lateral movement mechanism 5 includes: an arm 51 disposed at the upper and lower ends of the door 2 so as to be rotatable around a fulcrum 51 a at a position closer to the center of the door 2 than the pivoting mechanism 4 ; and an anchor 52 , is arranged at the opposing position of the arm 51 in the washing machine main body 3, and the arm 51 is interlocked with the handle 21 via a transmission mechanism not shown. The arm 51 is configured to rotate around the fulcrum 51a by operating the handle 21 at the closed position of the door 2. At this time, the arm 51 kicks the anchor 52 to cause the door 2 to move laterally mainly in the left and right direction by its reaction force. . After that, by pushing out the anchor 52 with the arm 51, the function of assisting the opening operation of the door 2 is realized.

As shown in Figures 3 and 4, the pivoting mechanism 4 includes: a shaft 41 protruding from the main body 3 of the washing machine to the door 2, that is, if illustrated in the bottom view of Figure 3, from the front side of the paper to the inside of the paper and the bearing portion 42 is provided at the upper and lower ends of the door 2, that is, if it is explained with FIG. 3, it is provided at the lower end of the door 2. The bearing part 42 is comprised by the member containing resin, metal, or both. And, at the initial stage of the opening operation of the door 2, the movement of the door 2 laterally moving in the left and right direction moves the inner shaft 41 (in) which becomes the suspension as shown in FIG. The outer shaft 41 (out) is moved in a direction away from the bearing portion 42 so that the outer shaft 41 is freed to realize the double-opening action.

A semi-cylindrical shaft rib 43 that prevents the door 2 from detaching from the shaft 41 during rotation is concentrically provided around the shaft 41 .

The bearing part 42 has: the shaft hole 42a, when the door 2 moves laterally, the shaft center coincides with the shaft 41 serving as the fulcrum of rotation; the opening 42b makes the shaft relatively move away from the shaft hole 42a 41 is disengaged; and the rail groove 42c enables the shaft 41 to move between the shaft hole 42a and the opening 42b. Regarding the surface of the bearing portion 42, the surface around the shaft hole 42a protrudes toward the front side of the drawing than other parts, and an arc-shaped first stepped portion 41d and a second stepped portion 41e centered on the shaft hole 42a are formed on the boundary thereof. . The distance from the center of the shaft hole 42a to the second step portion 41e is set to be large relative to the distance from the center of the shaft hole 42a to the first step portion 41d, and the distance between the first step portion 41d and the second step portion 41e is set to be large. A connection step portion 42f extending substantially in the radial direction of the shaft hole 42a is formed between the end portions.

When the door 2 is located at the closed position, the first stepped portion 41d is located at a position in contact with the inner diameter 43a of the shaft rib 43 as shown in FIG. 3 . When the door 2 starts to rotate and move laterally from this position along with the opening operation of the door 2, the end surface 43b of the shaft rib 43 is in contact with the connection step portion 42f as viewed from the fixed side, and moves along the connection step portion. 42f is relatively moved, and then, as shown in FIG. 4 , the inner diameter 43a of the shaft rib 43 climbs up the outer shape of the concentric second stepped portion 41e. Thereafter, the inner diameter 43a of the shaft rib 43 moves along the second stepped portion 41e.

On the other hand, when the door 2 is laterally moved and rotated, the outer shaft 41 (out) moves relative to the shaft rib 43 along the rail groove 42c, and finally disengages from the opening 42b, thereby releasing the engagement between the shaft 41 and the bearing portion 42. .

If the opening direction of the door 2 is left and right opposite, then the relationship between the inside as the suspension and the outside as the anti-suspension is opposite, and the door 2 can be opened to the opposite side in a bilaterally symmetrical state as shown in FIG. 4 .

In the above structure, this embodiment is provided between the door 2 and the main body 3 of the washing machine: a latch mechanism 6 shown in FIGS. The locking mechanism 7 shown in FIGS. 11 to 14 is used to ensure water sealing during washing operation.

FIG. 10 is a diagram for explaining disadvantages in a case where a general lock mechanism 107 is provided as a comparative example. FIG. 11 is a diagram showing the configuration of the lock mechanism 7 on the side of the washing machine body 3 when the lock mechanism 7 of the present embodiment is in an unlocked state. Fig. 12 is a diagram showing the configuration of the locking mechanism 7 on the side of the washing machine body 3 when the locking mechanism 7 is in a locked state. FIG. 13 is a diagram showing the structure of the door side constituting the lock mechanism 7 . Fig. 14 is a schematic cross-sectional view of the locking portion when the locking mechanism 6 is in the locked state.

In the case of a double-leaf door 2 that utilizes the lateral movement of the door 2 as in this embodiment, if only the same latch mechanism and lock mechanism as the ordinary single-leaf door 2 are provided, the latch mechanism and the lock mechanism will operate differently from each other. The action of the lateral movement mechanism 5 interferes.

FIG. 5 is a diagram showing the latch mechanism 6 according to the present embodiment, and a description will be given of disadvantages when a latch mechanism similar to that of an ordinary single-loading washing machine is provided using this diagram. Even if a general latch mechanism is used, the latch claws 61 protruding from the left and right ends of the door 2 toward the washing machine body 3 can be elastically engaged with the hooks 62 of the washing machine body 3 like the latch mechanism 6 of this embodiment. However, the structure for operating the latch pawl 61 through the handle 21 for latch release may be common. However, the illustrated

gears

63a, 63b are absent.

The latch claw 61 is set so that the hooking direction faces outward, rotates when the handle 21 is operated, and is elastically returned to a predetermined position by a spring (not shown) when the handle 21 is released. In the closed position of the door 2, the latch claw 61 is engaged with the hook 62 of the washing machine main body 3 set so that the hooking direction faces inward at the elastically reset position.

When the handle 21 on the right side in FIG. 6 is operated from this state, for example, the latch claw 61 (in) on the inside that becomes the suspension is still hooked on the hook 62, and the latch claw 61 (out) on the outside that becomes the anti-suspension passes through. The handle 21 is grasped and temporarily released from the hook 62 .

Afterwards, when the lateral movement mechanism 5 works so that the door 2 slides to the right in the figure as shown in FIG. As the door 2 moves laterally, the latch claw 61 (out) on the outside moves in a direction to be engaged with the hook 62 .

At this time, since the normal latch claw 61 does not consider the lateral movement of the door 2, it is not clear whether the inner latch claw 61(in) moves to the position where the engagement with the hook 62 is released. As for the outer latch claw 61 (out), the latch cannot be released because it is caught on the hook 62 again.

Therefore, the present embodiment is configured such that the movement distance and the shape of the latch claw 61 are set so that the latch claw 61 (in) positioned inside moves to a position sufficiently separated from the hook 62 by lateral movement of the door 2 . , the shape of the hook 62 , and the latch claw 61 (out) located on the outside is operated so as to exceed the amount of lateral movement to separate from the hook 62 .

The movement of the latch claw 61 to the position where it can be fully separated is not only the case where the latch claw 61 moves to a position where it does not interfere with the hook 62 at all, even if there is a slight interference, as long as the latch claw 61 can move along the latch shown in FIG. It is sufficient that the door 2 is opened while the underside slope 61a of the pawl 61 is rotated in the direction of escaping the hook 62 .

In addition, in order to achieve an operation exceeding the amount of lateral movement in the latch claw 61 , an amplification mechanism that amplifies the operation amount of the handle 21 , that is, the operation angle, and transmits it to the latch claw 61 is interposed between the handle 21 and the latch claw 61 . 63. The enlargement mechanism 63 includes: a first gear 63a driven by the handle 21; and a second gear 63b formed at the base end of the latch pawl 61 and engaged with the first gear 63a, the enlargement mechanism 63 can pass through the first gear 63a, the second gear 63b, and the second gear 63b. The second gear 63b amplifies the rotation angle of the handle 21 to make the latch pawl 61 work.

In the absence of such an enlargement mechanism 63, the position of the latch pawl 41 (out) of FIG. ) corresponds to the first operating position which is shallower than when the handle 21 is held at its maximum, and there remains a pull-out margin on the handle 21 .

Therefore, as shown in FIG. 8 , by further gripping the handle 21 from the first operating position to the second operating position, the outer latch pawl 61 (out) can be further opened and separated from the hook 62 .

On the contrary, in the case of closing the door 2 from the open position, as shown in the state transition diagram from left to right in FIG. The hook 62 can be passed through the reverse rotation so as to exceed the amount of lateral movement of the door 2 .

In addition, FIG. 10 has shown the case where the lock mechanism 107 similar to that of a general single-loading washing machine is used for the lock of the door 2 as a comparative example. The lock mechanism 107 is in a locked state by accommodating a lock pin 107a protruding rearward of the door 2 in a lock pin insertion hole 107b provided in the washing machine main body 3 .

The locking pin 107a is arranged to protrude rearward from the left and right ends of the door 2, and the door 2 is rotated in this state, and the width of the locking pin 107a passes through the opening width of the locking pin insertion hole 107b along the rotation track. However, when the shaft 41 is located at the position of the shaft hole 42a by the lateral movement mechanism 5, in the case of the left view of FIG. The pin is inserted into the hole 107b.

Conversely, when the lock pin 107a is inserted into the lock pin insertion hole 107b as shown in the right view of FIG. 10, the position of the shaft 41 and the shaft hole 42a do not match, and the door 2 cannot be rotated.

That is, in FIG. 10, if the locking mechanism 107 of either the inner side of the suspension or the outer side of the anti-suspension is established, the locking mechanism 107 of either side is not established, but this is mainly because the inner side where the radius of rotation becomes smaller phenomenon that occurs in the locking mechanism 107.

Therefore, as shown in FIGS. 11 to 13 , this embodiment adopts the following structure: the locking pin 71 of the locking mechanism 7 is sunk into the locking pin receiving hole 71a provided on the main body 3 of the washing machine, and the locking pin is moved by protruding and sinking. 71 is engaged with a lock pin engaging hole 72 provided in the door 2 .

The lock pin 71 has an L-shape in which the tip of a shaft extending from the washing machine body 3 toward the door 2 is bent in the horizontal direction, and is rotatable around a fulcrum. The lock pin accommodating hole 71a is set to a shape and depth capable of accommodating the lock pin 71 in the sunken state. The lock pin engagement hole 72 on the door 2 side has a wide opening 72a through which the shaft and tip of the lock pin 71 can pass; The shaft portion of the pin 71 is further drawn in; and the engaged portion 72c is located adjacent to the narrow opening 72b and engaged with the horizontal portion of the lock pin 71 on the back side.

In a state where the lock pin 71 is engaged with the lock pin engaging hole 72 , the rotation of the lock pin 71 is electromagnetically locked, whereby the door 2 is held in the locked state. When the electromagnetic lock of the lock pin 71 is released from this position, the lock pin 71 is disengaged from the lock pin engaging hole 72 and accommodated in the lock pin receiving hole 71 a in a sunken state.

Accordingly, the lock pin 71 is not interposed between the door 2 and the washing machine body 3 in the unlocked state, and the lock pin 71 does not become an obstacle even if the door 2 moves laterally.

The latch mechanism 6 is disposed above the lock mechanism 7 and above the door 2 .

As mentioned above, the washing machine 1 of the present embodiment can double-open the door 2 through the lateral movement of the door 2. In such a structure, a pair of latch mechanisms 6 are provided at the left and right ends of the door 2 to close the door. At 2 o'clock, make the latch claw 61 on the side of the door 2 elastically engaged with the hook 62 of the washing machine main body 3 to tie the door 2 to the washing machine main body 3; and a pair of handles 21 for latch release, and a pair of latches For the mechanism 6, when the handle 21 is operated from the closed position of the door 2, the latch pawl 61 (in) of the latch mechanism 6 located on the inner side as the fixed side is moved to a position capable of engaging with the hook by utilizing the lateral movement of the door 2. 62 separated position, on the other hand, make the latch claw 61 (out) of the latch mechanism 6 located on the outside as the anti suspension move more than the amount of lateral movement so that the latch claw 61 (out) can be separated from the hook 62 .

Thus, even if the door 2 moves laterally, the latch claw 61 of the latch mechanism 6 can be properly separated from the hook 62 of the washing machine main body 3, so that the latch claw 61 can be prevented from colliding with the latch claw 61 when the door 2 is opened or closed. When the hook 62 of the washing machine main body 3 interferes to prevent opening and closing.

In the washing machine 1 of this embodiment, the latch claw 61 of the latch mechanism 6 is set so that the engaging direction of the latch claw 61 and the hook faces outward.

By setting the hooking direction of the latch pawl 61 in this direction, it is possible to suitably realize an operation that does not interfere with the hook 62 regardless of whether it is the inner side that is the fixed side or the outer side that is the movable side.

The washing machine 1 of the present embodiment interposes an amplification mechanism 63 that amplifies the operation amount of the handle 21 and transmits it to the latch claw between the handle 21 and the latch claw 61 of the latch mechanism 6 .

Therefore, if the amount of lateral movement of the double door 2 is added to the amount of movement of the latch pawl 61 in the latch mechanism 6 of the single door 2, appropriate latch release can be reliably performed during the lateral movement.

When the lock mechanism 7 and the latch mechanism 6 are arranged in parallel, the latch mechanism 6 is disposed above the lock mechanism 7 and above the door 2 .

Therefore, the operation of the lock mechanism 7 can be reliably realized.

The washing machine of this embodiment can double-open the door 2 through the lateral movement of the door 2. In such a structure, a locking mechanism 7 is provided. 2 protruding forward; and a locking pin engagement hole 72, which is provided on the door 2, for a pair of locking pins 71 to engage. When the door 2 is closed, the lock is released, and the lock pin 71 is disengaged from the lock pin engaging hole 72 and inserted into the inside of the washing machine main body 3 .

By sinking the lock pin 71 , the lock pin 71 is not interposed between the door 2 and the washing machine main body 3 , so that the door 2 does not interfere with the lock pin 71 even if it moves laterally. Therefore, even if the lock mechanism 7 exists, the opening operation and closing operation of the door 2 can be performed appropriately.

Since the lock mechanism 7 performs the protrusion and sinking operation by rotating around the fulcrum, the movement of the lock pin can also be stabilized.

One embodiment of the present invention has been described above, but the specific configuration of each part is not limited to the above-mentioned embodiment.

For example, the purpose of the above-mentioned latch mechanism and locking mechanism is not to interfere with the lateral movement of the door, so the lateral movement mechanism and pivoting mechanism of the door are not limited to the structures shown in the illustrations.

In addition, specific structures of the latch mechanism and the lock mechanism can be modified in various ways without departing from the gist of the present invention.
