Summary of the Invention

[0007] To achieve the above objective, a washing machine according to one aspect of this invention comprises a washing machine body including a washing tub, and an upper lid covering the top of the washing tub, the upper lid including a first lid that slides horizontally, and a second lid that slides in the opening direction so that the first lids overlap in a plan view, and rotates around a first horizontal rotation axis with respect to the washing machine body.

[0008] In a washing machine according to one aspect of this invention, as described above, the top lid includes a first lid that slides horizontally, and a second lid that slides in the opening direction so that the first lid overlaps the second lid in a plan view, and rotates around a first horizontal rotation axis relative to the washing machine body. By sliding the first lid of the top lid so that it overlaps the second lid, the length required to open the top lid can be reduced, thus preventing the top lid from interfering with objects above, such as dryers or shelves. This prevents a decrease in the flexibility of the washing machine's installation location. Furthermore, in the case of a structure in which the top lid can be folded near the center, interference with objects above can be prevented when the top lid is open, but when folding the top lid, it is necessary to lift the entire top lid upwards, which may cause the hand to interfere with objects above when opening the top lid. On the other hand, by sliding the first lid, the length of the top lid can be reduced when the top lid is laid flat, thus preventing the hand from interfering with objects above when opening the top lid. As a result, the top lid can be opened easily while minimizing the reduction in the flexibility of the washing machine's installation location.

[0009] In the washing machine according to the first aspect described above, preferably, the top lid further includes a rotation fixing mechanism that fixes the rotational position of the second lid when the first lid is slid in the opening direction so that the first lid overlaps the second lid in a plan view, and the second lid is rotated upward around the first rotation axis. With this configuration, the top lid, which is opened with the first and second lids overlapping, can be fixed in the upward rotational position, and thus the top lid can be held in an open state.

[0010] In the washing machine according to the first aspect described above, preferably, the top lid further includes a sliding movement locking mechanism that locks the sliding movement of the first lid relative to the second lid. With this configuration, it is possible to suppress the sliding movement of the first lid relative to the second lid when the second lid is being rotated.

[0011] In this case, preferably, the sliding movement locking mechanism of the upper lid is configured such that when the first lid slides in the opening direction and the first lid overlaps the second lid in a plan view, and the second lid rotates upward around the first rotation axis and separates from the ground surface, the sliding movement of the first lid relative to the second lid is locked, and when the second lid rotates downward around the first rotation axis and touches the ground surface, the lock on the sliding movement of the first lid relative to the second lid is released. With this configuration, it is possible to effectively suppress the sliding movement of the first lid relative to the second lid when the second lid is rotating.

[0012] In the washing machine according to the first aspect described above, preferably, the top lid further includes a rotational movement locking mechanism that locks the rotational movement of the second lid when the sliding position of the first lid is not the fully open position, and unlocks the rotational movement of the second lid when the sliding position of the first lid is the fully open position. With this configuration, the first lid can be slid to the fully open position before the second lid can be rotated, so that the length of the top lid can be reliably reduced when it is rotated. As a result, interference between the top lid and objects above it can be effectively suppressed.

[0013] In the washing machine according to the first aspect described above, preferably, the second lid has a receiving section for accommodating the first lid when the first lid is slid in the opening direction. With this configuration, the first lid can be slid in the closing direction and accommodated in the receiving section of the second lid, thereby preventing the first lid from being exposed to a large extent when the second lid is rotated.

[0014] In the washing machine according to the first aspect described above, preferably, at least one of the first lid and the second lid is made of a transparent material. With this configuration, when the top lid is closed, the inside of the washing tub can be visually inspected through the top lid made of the transparent material.

[0015] In the washing machine according to the first aspect described above, preferably, the top lid further includes a common gripping part provided on the first lid for sliding the first lid and rotating the second lid, the gripping part being rotatable around a second rotation axis in the horizontal direction relative to the first lid. With this configuration, the sliding movement of the first lid and the rotation of the second lid can be performed while gripping the common gripping part, making it easy to open and close the top lid. In addition, since the gripping part rotates relative to the first lid, interference of the hand gripping the gripping part with an object above when rotating the second lid can be effectively prevented.

[0016] In this case, preferably, the gripping portion is provided on the first lid so as to protrude away from the first rotation axis. With this configuration, the gripping portion protrudes towards the user, making it easy to grasp. [Effects of the Invention]

[0017] According to this invention, as described above, the top lid can be easily opened while suppressing a decrease in the degree of freedom in where the washing machine can be installed. [Brief explanation of the drawing]

MODE FOR CARRYING OUT THE INVENTION

[0019] Hereinafter, embodiments embodying the present invention will be described based on the drawings.

[0020] Referring to Figures 1 to 13, the configuration of a washing machine 100 according to one embodiment of the present invention will be described.

[0021] As shown in Figure 1, the washing machine 100 is configured to wash laundry such as clothes, towels, and bedding. Specifically, the washing machine 100 washes the laundry with water and detergent, rinses the laundry with water, and dehydrates the laundry using centrifugal force. The washing machine 100 is a vertical washing machine in which the washing tub 11 rotates around a rotation axis in the vertical direction (Z direction), and the top lid 20 provided at the top can be opened and closed.

[0022] As shown in Figure 1, the washing machine 100 comprises a washing machine body 10 including a washing tub 11, and a top cover 20 that covers the top (Z1 direction side) of the washing tub 11 and rotates around a first rotation axis A1 in the horizontal direction (X direction).

[0023] The washing tub 11 is capable of storing water inside. When laundry is placed in the washing tub 11, washing is performed using the stored water. The washing tub 11 is rotatable around its vertical (Z-direction) axis of rotation. During the spin cycle, the washing tub 11 rotates around its vertical (Z-direction) axis of rotation. Furthermore, an agitator is provided at the bottom of the washing tub 11. The agitator is rotatable around its vertical (Z-direction) axis of rotation. The agitator rotates around its vertical (Z-direction) axis of rotation during both the washing and rinsing cycles.

[0024] Furthermore, the washing machine 100 is powered by a power outlet provided at the installation location. The washing machine 100 is also supplied with water from a water tap provided at the installation location. Specifically, the washing machine 100 is equipped with a water supply hose, the end of which is connected to the water tap, and water is supplied from the tap. The washing machine 100 is also equipped with a drain hose for drainage, and the water used in the washing tub 11 is drained through this drain hose.

[0025] In this embodiment, the top lid 20 includes a first lid 21 and a second lid 22, as shown in Figures 1 to 5. The first lid 21 slides horizontally. Specifically, when the top lid 20 is closed, the first lid 21 is slidable horizontally in the front-to-back direction (Y direction) relative to the second lid 22. The second lid 22 is positioned so that it overlaps the first lid 21 in a plan view when the first lid 21 is slid in the opening direction. Specifically, when the top lid 20 is closed, the first lid 21 is slid backward (Y2 direction) relative to the second lid 22, so that the first lid 21 and the second lid 22 overlap in a plan view. The second lid 22 also rotates around a first horizontal rotation axis A1 relative to the washing machine body 10.

[0026] As shown in Figures 1 and 2, when the top lid 20 is in the closed state, covering the top of the washing tub 11, the second lid 22 is in a position where it has rotated forward (Y1 direction) and downward (Z2 direction) around the first rotation axis A1, and the first lid 21 is in a position where it has slid forward (Y1 direction) relative to the second lid 22.

[0027] As shown in Figure 5, when the top lid 20 is in the open position, which leaves the top of the washing tub 11 open, the first lid 21 slides relative to the second lid 22 in a direction approaching the first rotation axis A1, and the second lid 22 rotates in the rearward (Y2 direction) and upward (Z1 direction) direction when rotating around the first rotation axis A1.

[0028] As shown in Figure 4, when the upper cover 20 is in a half-open state between the open and closed state, the second cover 22 is in a position where it has rotated forward (Y1 direction) and downward (Z2 direction) around the first rotation axis A1, and the first cover 21 is in a position where it has slid backward (Y2 direction) relative to the second cover 22.

[0029] The first lid portion 21 and the second lid portion 22 are formed from transparent materials. Specifically, the first lid portion 21 includes a frame member made of an opaque resin and a plate-shaped transparent member fixed to the frame member. The transparent member is made of, for example, glass. The transparent member may also be made of a transparent resin such as acrylic. The second lid portion 22 includes a frame member made of an opaque resin and a plate-shaped transparent member fixed to the frame member. The transparent member is made of, for example, glass. The transparent member may also be made of a transparent resin such as acrylic.

[0030] As shown in Figure 3, the second lid 22 has a housing portion 221 that accommodates the first lid 21 when the first lid 21 is slid in the opening direction. In other words, the first lid 21 is housed in the housing portion 221 of the second lid 22 when it is in the open and partially open states.

[0031] As shown in Figures 4 to 7, the top cover portion 20 includes a gripping portion 23. Specifically, the gripping portion 23 is provided on the first cover portion 21. The gripping portion 23 is also provided in common to slide the first cover portion 21 and rotate the second cover portion 22. In other words, when the user opens or closes the top cover portion 20, the gripping portion 23 is gripped and the top cover portion 20 is moved. The gripping portion 23 has a substantially U-shape, for example, as shown in Figure 3. The gripping portion 23 is also rotatable around a second horizontal pivot axis A2 relative to the first cover portion 21.

[0032] Furthermore, as shown in Figures 4 to 7, the gripping portion 23 is provided on the first cover portion 21 so as to protrude in a direction away from the first rotation axis A1.

[0033] Furthermore, the second lid 22 is provided with a locking mechanism that locks the top lid 20 to prevent it from opening while the washing machine 100 is performing a wash.

[0034] As shown in Figures 6 and 7, the upper cover portion 20 includes a rotation fixing mechanism 30 that fixes the rotational position of the second cover portion 22 when the first cover portion 21 is slid in the opening direction and the first cover portion 21 overlaps the second cover portion 22 in a plan view, and the second cover portion 22 is rotated upward around the first rotation axis A1.

[0035] Specifically, the rotation locking mechanism 30 includes an engaging portion 31 provided on the housing 12 of the washing machine body 10 and an engaged portion 32 provided on the second lid portion 22 of the upper lid portion 20. As shown in Figure 6, when the second lid portion 22 moves to a position rotated in the open direction (rearward (Y2 direction) and upward (Z1 direction)), the engaging portion 31 engages with the engaged portion 32 of the second lid portion 22, preventing the second lid portion 22 from rotating in the closed direction (forward (Y1 direction) and downward (Z2 direction)). The engaging portion 31 is made of an elastically deformable material. This allows the engaged portion 32 to overcome the engaging portion 31 when force is applied by the user to open or close the second lid portion 22.

[0036] Furthermore, as shown in Figures 8 to 10, the top cover portion 20 includes a slide movement locking mechanism 40 that locks the sliding movement of the first cover portion 21 relative to the second cover portion 22.

[0037] Specifically, the slide movement locking mechanism 40 includes a member housing portion 41, an engaging member 42, and a biasing member 43, which are provided on the first lid portion 21. The slide movement locking mechanism 40 also includes an engaging hole portion 44, which is provided on the second lid portion 22. Furthermore, the slide movement locking mechanism 40 includes a protrusion 45 provided on the housing 12 of the washing machine body 10.

[0038] Furthermore, as shown in Figures 9 and 10, the sliding movement locking mechanism 40 of the upper lid 20 locks the sliding movement of the first lid 21 relative to the second lid 22 when the first lid 21 slides in the opening direction and overlaps the second lid 22 in a plan view, and the second lid 22 is rotated upward around the first rotation axis A1 and moves away from the ground surface. In other words, when the first lid 21 slides in the opening direction and fits into the second lid 22 (see Figure 9), and the second lid 22 is rotated upward around the first rotation axis A1 and moves away from the ground surface (see Figure 10), the engaging member 42 provided on the first lid 21 is biased downward by the biasing member 43 within the member housing 41, and the engaging member 42 of the first lid 21 enters into the engaging hole 44 of the second lid 22 and engages. This restricts (locks) the sliding movement of the first lid 21 relative to the second lid 22.

[0039] Furthermore, as shown in Figures 9 and 10, the sliding movement locking mechanism 40 of the upper lid 20 releases the lock on the sliding movement of the first lid 21 relative to the second lid 22 when the second lid 22 is rotated downward around the first rotation axis A1 and makes contact with the ground surface. In other words, when the first lid 21 is slid in the opening direction and fits into the second lid 22 (see Figure 10), and the second lid 22 is rotated downward around the first rotation axis A1 and makes contact with the ground surface (see Figure 9), the engaging member 42 provided on the first lid 21 is pressed upward by the protrusion 45 provided on the housing 12, and the engagement between the engaging member 42 of the first lid 21 and the engaging hole 44 of the second lid 22 is released. This releases the lock on the sliding movement of the first lid 21 relative to the second lid 22.

[0040] Furthermore, as shown in Figures 11 to 13, the top cover portion 20 includes a rotational movement locking mechanism 50 that locks the rotational movement of the second cover portion 22 when the sliding position of the first cover portion 21 is not the fully open position, and unlocks the rotational movement of the second cover portion 22 when the sliding position of the first cover portion 21 is the fully open position.

[0041] Specifically, as shown in Figure 11, the rotational movement locking mechanism 50 is provided on both sides of the washing machine body 10 in the left-right direction (X direction). The rotational movement locking mechanism 50 includes a guide portion 51 provided on the housing 12 of the washing machine body 10. The rotational movement locking mechanism 50 also includes an engaging portion 52 provided on the first lid portion 21. When the guide portion 51 engages with the engaging portion 52 from above, the upward movement of the first lid portion 21 on which the engaging portion 52 is provided is restricted. Similarly, the upward rotation of the second lid portion 22 connected to the first lid portion 21 is also restricted.

[0042] The guide portion 51 is provided on both sides of the housing 12 in the left-right direction (X direction). Furthermore, as shown in Figure 11, the guide portion 51 is positioned in the region where the first lid portion 21 is located in the closed state of the upper lid portion 20 in the front-rear direction (Y direction). In other words, when the first lid portion 21 is sliding forward (Y1 direction) relative to the second lid portion 22, the guide portion 51 is positioned above the engaging portion 52. Also, as shown in Figure 12, the guide portion 51 is not positioned in the region where the second lid portion 22 is located in the closed state of the upper lid portion 20 in the front-rear direction (Y direction). Therefore, as shown in Figure 13, the guide portion 51 can move the first lid portion 21 and the second lid portion 22 upward when the sliding position of the first lid portion 21 is in the fully open position.

[0043] (Effects of this embodiment) In this embodiment, the following effects can be obtained.

[0044] In this embodiment, as described above, the top lid 20 includes a first lid 21 that slides horizontally, and a second lid 22 that slides in the opening direction so that the first lid 21 overlaps the second lid 22 in a plan view, and rotates around a first horizontal rotation axis A1 relative to the washing machine body 10. As a result, by sliding the first lid 21 of the top lid 20 so that it overlaps the second lid 22, the length required to open the top lid 20 can be reduced, so that even if a dryer 200 (see Figure 5) or shelves or structures for placing detergent and small items are placed above, interference between the top lid 20 and the objects above can be suppressed. This prevents a decrease in the degree of freedom in the installation location of the washing machine 100. Furthermore, in the case of a structure in which the top lid can be folded near the center, when the top lid is open, it is possible to prevent the top lid from interfering with objects above it. However, when folding the top lid, it is necessary to lift the entire top lid upwards, so that when opening the top lid, the hand may interfere with objects above it. On the other hand, by sliding the first lid 21, the length of the top lid 20 can be reduced when the top lid 20 is laid flat, thus preventing the hand from interfering with objects above it when opening the top lid 20. As a result, the top lid 20 can be easily opened while preventing a decrease in the degree of freedom in the installation location of the washing machine 100.

[0045] Furthermore, in this embodiment, as described above, the top cover portion 20 includes a rotation fixing mechanism 30 that fixes the rotational position of the second cover portion 22 when the first cover portion 21 is slid in the opening direction so that the first cover portion 21 overlaps the second cover portion 22 in a plan view, and the second cover portion 22 is rotated upward around the first rotation axis A1. As a result, the top cover portion 20, which is opened with the first cover portion 21 and the second cover portion 22 overlapping, can be fixed in the upper rotational position, and thus the top cover portion 20 can be held in the open state.

[0046] Furthermore, in this embodiment, as described above, the upper lid portion 20 includes a slide movement locking mechanism 40 that locks the sliding movement of the first lid portion 21 relative to the second lid portion 22. This prevents the first lid portion 21 from sliding relative to the second lid portion 22 when the second lid portion 22 is being rotated.

[0047] Furthermore, in this embodiment, as described above, the sliding movement locking mechanism 40 of the upper cover 20 locks the sliding movement of the first cover 21 relative to the second cover 22 when the first cover 21 slides in the opening direction and overlaps the second cover 22 in a plan view, and the second cover 22 is rotated upward around the first rotation axis A1 and moves away from the ground surface. The sliding movement locking mechanism 40 of the upper cover 20 also releases the lock on the sliding movement of the first cover 21 relative to the second cover 22 when the second cover 22 is rotated downward around the first rotation axis A1 and makes contact with the ground surface. This effectively prevents the first cover 21 from sliding relative to the second cover 22 when the second cover 22 is rotating.

[0048] Furthermore, in this embodiment, as described above, the top cover portion 20 includes a rotational movement locking mechanism 50 that locks the rotational movement of the second cover portion 22 when the sliding position of the first cover portion 21 is not the fully open position, and unlocks the rotational movement of the second cover portion 22 when the sliding position of the first cover portion 21 is the fully open position. As a result, the first cover portion 21 can be slid to the fully open position before the second cover portion 22 can be rotated, so that the length of the top cover portion 20 can be reliably reduced while it is rotating. As a result, interference between the top cover portion 20 and objects above it can be effectively suppressed.

[0049] Furthermore, in this embodiment, as described above, the second lid 22 has a housing portion 221 that accommodates the first lid 21 when the first lid 21 is slid in the opening direction. This allows the first lid 21 to be slid in the closing direction and housed in the housing portion of the second lid 22, thereby suppressing the large exposure of the first lid 21 when the second lid 22 is rotated.

[0050] Furthermore, in this embodiment, as described above, the first lid portion 21 and the second lid portion 22 are formed of a transparent material. This allows the inside of the washing tub 11 to be visually inspected through the transparent material of the upper lid portion 20 when the upper lid portion 20 is closed.

[0051] Furthermore, in this embodiment, as described above, the top cover portion 20 is provided on the first cover portion 21 and includes a common gripping portion 23 for sliding the first cover portion 21 and rotating the second cover portion 22. The gripping portion 23 is rotatable around a second horizontal pivot axis A2 relative to the first cover portion 21. This allows the sliding of the first cover portion 21 and the rotation of the second cover portion 22 to be performed while gripping the common gripping portion 23, thus facilitating the opening and closing of the top cover portion 20. In addition, since the gripping portion 23 rotates relative to the first cover portion 21, interference of the hand gripping the gripping portion 23 with an object above can be effectively prevented when rotating the second cover portion 22.

[0052] Furthermore, in this embodiment, as described above, the gripping portion 23 is provided on the first lid portion 21 so as to protrude in a direction away from the first rotation axis A1. As a result, the gripping portion 23 protrudes in front of the washing machine 100, making it easy to grip the gripping portion 23.

[0053] (modified version) It should be noted that the embodiments disclosed herein are illustrative and not restrictive in all respects. The scope of this invention is indicated by the claims for utility model registration rather than by the description of the embodiments described above, and further includes all modifications (modifications) within the meaning and scope equivalent to the claims for utility model registration.

[0054] In the above embodiment, an example was shown in which the top lid portion 20 includes a first lid portion 21 and a second lid portion 22, but the present invention is not limited thereto. In the present invention, a lid portion that slides or folds may be further provided at the tip of the first lid portion 21.

[0055] Furthermore, although the above embodiment shows an example in which a rotation fixing mechanism 30 is provided to fix the upper lid portion 20 in the open rotation position, the present invention is not limited to this. In the present invention, when the upper lid portion 20 is in the open rotation position, it is not necessary to provide a rotation fixing mechanism 30 by preventing it from returning due to gravity. Alternatively, a damper member may be provided on the upper lid portion 20 to suppress the speed at which it rotates from the open position to the closed position.

[0056] Furthermore, although the first embodiment described above shows an example in which both the first lid portion 21 and the second lid portion 22 of the upper lid portion 20 are formed of a transparent material, the present invention is not limited to this. In the present invention, either the first lid portion 21 or the second lid portion 22 of the upper lid portion 20 may be formed of a transparent material.

[0057] Furthermore, in the above embodiment, an example was shown in which a rotational movement locking mechanism 50, which locks the rotational movement of the second lid 22 when the sliding position of the first lid 21 of the upper lid 20 is not the fully open position, is provided on both sides in the left-right direction of the washing machine body 10. However, the present invention is not limited to this. In the present invention, the rotational movement locking mechanism 50 may be provided on only one side in the left-right direction of the washing machine body 10.

[0058] Furthermore, a rotational movement locking mechanism may be provided to restrict the movement of the pivot axis. For example, the movement of the pivot axis of the second lid 22 may be restricted by sliding the first lid 21 and pushing it into the second lid 22.

[0059] Furthermore, although the above embodiment shows an example in which the gripping portion 23 provided on the upper lid portion 20 is rotatable around the second rotation axis A2, the present invention is not limited to this. In the present invention, the gripping portion may be fixedly provided on the upper lid portion. Also, the gripping portion may be formed in the shape of a handle or in the shape of a recess.

[0060] Furthermore, although the above embodiment shows an example in which the washing machine 100 does not have a function to dry laundry with hot air, the present invention is not limited to this. In the present invention, the washing machine may have a function to dry laundry with hot air. [Explanation of symbols]
