Description

Technical Field

[0001] The present invention relates to a laundry unit having a drum washing machine and a squeeze-type washing machine for performing squeeze washing. Background Art

[0002] There is a squeezing type washing machine that performs squeezing washing without damaging the fibers when washing laundry with fragile fibers (e.g., Patent Document 1). The squeezing type washing machine of Patent Document 1 comprises: a cover that opens and closes a loading port of a washing tub; a squeezing washing member disposed on the cover; and a driving mechanism disposed on the cover.

[0003] The squeezing cleaning member is connected to the lower end of the threaded shaft of the driving mechanism, and the threaded shaft is arranged in a manner of penetrating the cover. When the threaded shaft moves along the axis by rotating the nut, the squeezing cleaning member moves while maintaining a state of being substantially parallel to the cover. The lower surface of the squeezing cleaning member is substantially flat, and the laundry is uniformly pressed into the entire washing tub during squeezing cleaning.

[0004] The squeeze-type washing machine of Patent Document 1 is structured to wash laundry by pressing the laundry with a single squeeze-washing member. However, compared with manual squeeze-washing, the laundry moves less and the squeeze-washing is insufficient.

[0008] Problems to be solved by the invention

[0009] Therefore, an object of the present invention is to provide a laundry unit that can fully perform squeeze washing of laundry.

[0010] Solutions for solving problems

[0011] That is, the laundry unit of the present invention is characterized in that it comprises: a drum washing machine; and a squeeze-type washing machine, which is arranged below the drum washing machine, and the squeeze-type washing machine has: a washing container, which is accommodated in a box; and a plurality of squeeze members, which reciprocate between the interior of the washing container and the upper exterior of the washing container.

[0012] Preferably, in the laundry unit of the present invention, the washing container is configured to be pullable from the inside of the housing in a state where the plurality of pressing members are all located above and outside the washing container.

[0013] Preferably, in the laundry unit of the present invention, the plurality of squeezing members are arranged from the front side to the back side, and the washing container is arranged so as to be able to be pulled out from the interior of the housing when at least the squeezing member located on the back side among the plurality of squeezing members is located above and outside the washing container.

[0014] Preferably, in the laundry unit of the present invention, a movable plate is provided at the upper end portion of the back side wall surface of the washing container, and when the movable plate contacts the pressing member and is pressed toward the back side, the movable plate can swing toward the back side with the lower end portion of the movable plate as a fulcrum, and move to the original position when it no longer contacts the pressing member.

[0015] Effects of the Invention

[0016] In the laundry unit of the present invention, a plurality of squeezing members are independently moved in the up-down direction to press the laundry contained in the washing container up-down, thereby achieving the same fabric damage and cleaning power as manual squeezing washing for laundry with a "hand wash" mark, for example. In addition, the drum washing machine performs drum washing while the squeezing washing machine performs squeezing washing for delicate laundry, thereby washing them separately at the same time, which is beneficial to shortening the washing time.

[0017] The laundry unit of the present invention is configured to pull out a washing container for placing laundry to be squeezed and washed, and to lower a squeezing member into the washing drum container during washing so that the squeezing member contacts the laundry in the container to perform squeezing and washing. Conversely, the squeezing member is moved upward to the upper outside of the washing drum container before and after squeezing and washing, thereby preventing contact with the squeezing member when the washing drum container is pulled out.

[0018] In the laundry unit of the present invention, a portion of the front side of the washing container can be pulled out from the inside of the housing to accommodate laundry in the washing container or to take out laundry in the washing container.

[0019] In the laundry unit of the present invention, when the pressing member is located inside the washing container, when the washing container is to be pulled out from the inside of the housing, the pressing member contacts the back side wall of the washing container, and at this time, the movable plate provided on the upper end portion of the back side wall of the washing container swings toward the back side, so that the washing container can be pulled out from the inside of the housing regardless of the up-down position of the pressing member.

[0029] Hereinafter, a laundry unit according to an embodiment of the present invention will be described with reference to the drawings.

[0030] (First Embodiment)

[0031] Figure 1 (a) and Figure 1 (b) is a front view and a side view of the laundry unit 1 according to the first embodiment of the present invention. Figure 2 Observed from the side Figure 1 A longitudinal sectional view of a squeeze-type washing machine 5 is Figure 1 Cross-sectional view taken along line a1-a1 of (a). Figure 3 Observe from the front Figure 1 A longitudinal sectional view of a squeeze-type washing machine 5 is Figure 1 (b) is a cross-sectional view taken along line a2-a2.

[0032] The laundry unit 1 of this embodiment is provided with a base 1a below the drum washing machine 3, and a squeeze washing machine 5 is inserted into the base 1a.

[0033] The drum washing machine 3 has a rectangular parallelepiped housing 2. Inside the housing 2 are: an outer drum 3a having a bottomed cylinder having an axis extending substantially horizontally; a drum 3b having a bottomed cylinder disposed inside the outer drum 3a; and a driving device 3c for rotating the outer drum 3a and the drum 3b. An opening and closing cover 2a for opening and closing the opening for the laundry to enter and exit the drum 3b is mounted on the front surface of the housing 2.

[0034] The squeeze-type washing machine 5 has a rectangular box 5a. Inside the box 5a are arranged: a concave washing container 5A for accommodating washing and washing water; and a squeeze-type upper and lower working unit 5C, which is arranged above the washing container 5A. The washing container 5A is arranged so that it can be pulled out from the inside of the box 5a to the front side. Figure 2 In FIG. 1 , the dotted line diagram shows a state where the washing container 5A is pulled out from the interior of the housing 5a.

[0035] like Figure 2 and Figure 3 As shown, the upper and lower working units 5C have two push bases 51 for squeezing and cleaning the laundry. The two push bases 51 are respectively arranged on the left and right sides of the box body 5a when viewed from the front. The push bases 51 contact and press the laundry in the washing container 5A, thereby imparting mechanical force for cleaning.

[0036] The upper and lower working unit 5C has two squeezing mechanisms 5C1 and 5C2 for independently moving the two push-pull seats 51 up and down. The two push-pull seats 51 move alternately in a reciprocating manner between the inside of the washing container 5A and the upper outside of the washing container 5A. That is, when one of the two push-pull seats 51 moves upward, the other moves downward. It should be noted that the structure of the squeezing mechanism 5C2 is the same as that of the squeezing mechanism 5C1, so the structure of the squeezing mechanism 5C1 will be described in detail below.

[0037] The extrusion mechanism 5C1 includes: a crank holder 52; a crankshaft 53 supported by the crank holder 52; two hanger cams 54 assembled on the crankshaft 53; and a slide crank 55 fixed to the lower end of each hanger cam 54, and two push bases 51 fixed to the lower end of the two slide cranks 55.

[0038] The crank bracket 52 includes a support portion 52a that rotatably supports the front end of the crankshaft 53, and a support portion 52b that rotatably supports the back end of the crankshaft 53. The crankshaft 53 includes a shaft 53a that horizontally extends along the front-back direction of the washing machine 1, and two eccentric portions 53b that are convexly bent outward from the shaft 53a. The two eccentric portions 53b are separated and arranged in the front-back direction of the washing machine 1.

[0039] The two eccentric portions 53b each have a snap-fit ​​portion 53b1 arranged parallel to the horizontal bar shaft 53a. The two eccentric portions 53b are formed to be convex in the same direction in the circumferential direction of the horizontal bar shaft 53a. When one of the two eccentric portions 53b is convex downward relative to the horizontal bar shaft 53a, the other eccentric portion 53b is also convex downward relative to the horizontal bar shaft 53a.

[0040] On the inner side of the crank bracket 52, two hanger cams 54 are separated and arranged in the left-right direction of the washing machine 1. The hanger cam 54 has a rectangular parallelepiped shape, and a long hole 54a extending in the horizontal direction is formed near the upper end thereof. The engaging portion 53b1 of the eccentric portion 53b of the crankshaft 53 is inserted into the long hole 54a of the hanger cam 54, thereby the hanger cam 54 is held on the crankshaft 53. When the crankshaft 53 is driven to rotate, the engaging portion 53b1 rotates with the horizontal bar shaft 53a as a fulcrum, and with the rotation, the engaging portion 53b1 moves in the long hole 54a, and the hanger cam 54 moves in the up-down direction.

[0041] Sliding cranks 55 are fixed to the lower ends of the two hanging cams 54, respectively. Push-pull seats 51 are fixed to the lower ends of the two sliding cranks 55. The push-pull seats 51 have a rectangular parallelepiped shape extending in the front-rear direction of the washing machine 1, and are arranged approximately horizontally. The push-pull seats 51 reciprocate in the vertical direction when performing squeezing washing. In this way, in the squeezing mechanism 5C1, when the crankshaft 53 is driven to rotate, the hanging cams 54, the sliding cranks 55, and the push-pull seats 51 reciprocate in the vertical direction as a whole.

[0042] In addition, the back side end of the crankshaft 52 of the extrusion mechanism 5C1 is connected to the output shaft of the motor 61 via the joint 60. A bevel gear is mounted on the joint 60, and a bevel gear is mounted on the motor shaft of the motor 61. These bevel gears are all helical gears and mesh with each other. Therefore, the crankshaft 52 of the extrusion mechanism 30C1 can be rotated and driven by the motor 61.

[0043] A first gear 62 is fixed to the horizontal shaft 53a of the crankshaft 53 of the extrusion mechanism 5C1, and a first gear 62 is also fixed to the horizontal shaft 53a of the crankshaft 53 of the extrusion mechanism 5C2. A second gear (not shown) is arranged between these gears 62, and the outer peripheral surface of the first gear 62 on one side meshes with the outer peripheral surface of the second gear, and the outer peripheral surface of the first gear 62 on the other side meshes with the outer peripheral surface of the second gear.

[0044] In the squeeze-type washing machine 5 of this embodiment, position detection switches 65a and 65b for detecting the position of the push-pull seat 51 on the right side are arranged inside the housing 5a. The position detection switches 65a and 65b are, for example, optical sensors (non-contact reflection type). As described above, the two push-pull seats 51 move alternately in a reciprocating manner between the inside of the washing container 5A and the upper outside of the washing container 5A, so by detecting the position of the push-pull seat 51 on the right side, the position of the push-pull seat 51 on the left side can also be sensed.

[0045] The position detection switch 65a receives reflected light from the push-pull stand 51 to detect that the push-pull stand 51 moving in the vertical direction is located above the upper end of the washing container 5A (the state of being located at the upper end position when performing vertical reciprocating movement).

[0046] The position detection switch 65b receives reflected light from the push-pull seat 51 to detect that the push-pull seat 51 moving in the vertical direction is located in the washing container 5A (the push-pull seat 51 is located at the lower end position when the push-pull seat 51 reciprocates vertically).

[0047] It should be noted that a transparent portion 5A1 is formed on the back side wall of the washing container 5A, through which light for the position detection switch 65b to detect the push-pull seat 51 located in the washing container 5A passes.

[0048] The two push-pull seats 51 reciprocate between the inside of the washing container 5A and the outside of the upper part of the washing container 5A. When both push-pull seats 51 are located at the upper end position, the push-pull seats 51 are disposed above the upper end of the washing container 5A as a whole. Therefore, when the washing container 5A is pulled out from the inside of the housing 5a, the push-pull seats 51 are disposed at the upper end position in advance, so that the washing cylinder container 5A can be prevented from contacting with the pressing member 51 when being pulled out.

[0049] Then, when the laundry is placed in the pulled-out washing tub container 5A and the washing tub container 5A is inserted into the housing 5a, the push-pull seat 51 is pre-positioned at the upper end position to prevent contact with the pressing member 51 when the washing tub container 5A is inserted.

[0050] It should be noted that in the laundry unit 1, a water supply device for supplying washing water to the outer drum 3a and a drainage device for discharging washing water from the outer drum 3a are arranged inside the housing 2 of the drum washing machine 3, and a water supply device for supplying washing water to the washing drum container 5A and a drainage device for discharging washing water from the washing drum container 5A are arranged inside the housing 5a of the squeeze washing machine 5, but the description is omitted.

[0051] The laundry unit 1 of this embodiment comprises: a drum washing machine 3; and a squeeze washing machine 5, which is arranged below the drum washing machine 3, and the squeeze washing machine 5 comprises: a washing container 5A, which is accommodated in a box 5a; and a plurality of squeeze members 51, which reciprocate between the inside of the washing container 5A and the upper outside of the washing container 5A.

[0052] Thus, in the laundry unit 1 of this embodiment, the plurality of squeezing members 51 are independently moved in the up-down direction to press the laundry contained in the washing container 5A up-down, thereby achieving the same fabric damage and cleaning power as manual squeezing washing for laundry with a "hand wash" mark, for example. In addition, the squeezing washing machine 5 squeezing washing delicate laundry while the drum washing machine 3 performs drum washing, thereby washing them separately at the same time, which is conducive to shortening the washing time.

[0053] In the laundry unit 1 of the present embodiment, the washing container 5A is arranged to be pulled out from the inside of the housing 5a in a state where the plurality of pressing members 51 are all located above and outside the washing container 5A.

[0054] Therefore, the laundry unit 1 of this embodiment is configured to pull out the washing container 5A for placing the laundry to be squeezed and washed, and to lower the squeezing member 51 into the washing drum container during washing and make it contact with the laundry in the container to perform squeeze washing. Conversely, the squeezing member 51 is moved upward to the upper outside of the washing drum container 5A before and after the squeeze washing, thereby preventing contact with the squeezing member 51 when the washing drum container 5A is pulled out.

[0055] (Second Embodiment)

[0056] The laundry unit 101 of this embodiment is different from the laundry unit 1 of the first embodiment in the arrangement of two push-pull seats 51. It should be noted that the detailed description of the same structure of the laundry unit 101 of this embodiment as that of the laundry unit 1 of the first embodiment will be omitted.

[0057] In the laundry unit 101 of this embodiment, Figure 5As shown, the two push-pull seats 51 are respectively arranged on the front side and the back side of the box body 5a when viewed from the side. Therefore, when the washing container 5A is pulled out from the box body 5a to the front side, the push-pull seat 51 on the back side stops at an upwardly raised position, thereby the front side portion of the washing container 5A can be pulled out from the inside of the box body 5a regardless of the up-down position of the push-pull seat 51 on the front side.

[0058] In the laundry unit 101 of this embodiment, two push-pull seats 51 are arranged from the front side to the back side, and the washing container 5A is arranged so that the push-pull seat 51 located at the back side of the two push-pull seats 51 can be pulled out from the inside of the box 5a when the push-pull seat 51 located at the back side is located above and outside the washing container 5A.

[0059] In laundry unit 101 of this embodiment, a portion of the front side of washing container 5A can be pulled out from inside housing 5a to store laundry in washing container 5A or to take laundry out of washing container 5A.

[0060] (Third Embodiment)

[0061] The laundry unit 201 of this embodiment differs from the laundry unit 1 of the first embodiment in the structure of the washing container 5A. It should be noted that the detailed description of the structure of the squeeze type washing machine 301 of this embodiment that is the same as that of the squeeze type washing machine 1 of the first embodiment is omitted.

[0062] In the laundry unit 201 of this embodiment, a movable plate 5Aa is provided at the upper end portion of the back side wall surface 5Ab of the washing container 5A. Figure 7 As shown in (a), the lower end of the movable plate 5Aa is engaged with the engaging portion 5Ac formed at the upper end of the back side wall surface 5Ab in a swingable manner. A spring (not shown) is installed between the lower end of the movable plate 5Aa and the engaging portion 5Ac of the back side wall surface 5Ab. When the movable plate 5Aa swings, the movable plate 5Aa is urged by the spring in the direction of returning to a position parallel to the back side wall surface 5Ab.

[0063] Therefore, when the push-pull seat 51 is arranged in the washing container 5A, when the washing container 5A is pulled out from the inside of the box 5a, if the push-pull seat 51 contacts the movable plate 5Aa and is pressed toward the back side, Figure 7 As shown in (b), the engaging portion 5Ac of the movable plate 5Aa relative to the back side wall surface 5Ab is swung toward the back side with its lower end as a fulcrum. Therefore, no matter how the up-down direction position of the two push-pull seats 51 is, the front side part of the washing container 5A can be pulled out from the inside of the box body 5a.

[0064] Then, when the washing container 5A is inserted into the box 5a, the push-pull seat 51 disposed in the washing container 5A does not contact the movable plate 5Aa of the washing container 5A. Thus, the movable plate 5Aa is urged by the coil spring and thus returns to a position parallel to the back side wall surface 5Ab.

[0065] Note that a sealing structure is provided on the end surface of the movable plate 5Aa so that the washing water in the washing container 5A does not leak to the outside even when the movable plate 5Aa swings at the engagement portion 5Ac of the rear side wall surface 5Ab.

[0066] In the laundry unit 201 of the present embodiment, a movable plate 5Aa is provided at the upper end portion of the back side wall 5Ab of the washing container 5A. When the movable plate 5Aa contacts the push-pull seat 51 and is pressed toward the back side, it can swing toward the back side with the lower end portion of the movable plate 5Aa as a fulcrum, and move to its original position when it no longer contacts the push-pull seat 51.

[0067] Therefore, in the laundry unit 201 of the present embodiment, when the push-pull seat 51 is located inside the washing container 5A, when the washing container 5A is to be pulled out from the inside of the housing 5a, the push-pull seat 51 contacts the back side wall 5Ab of the washing container 5A, and at this time, the movable plate 5Aa provided on the upper end portion of the back side wall 5Ab of the washing container 5A will swing toward the back side, so regardless of the up and down position of the push-pull seat 51, the washing container 5A can be pulled out from the inside of the housing 5a.

[0068] As mentioned above, although embodiment of this invention was demonstrated, the specific structure of each part is not limited to the said embodiment.

[0069] For example, in the first to third embodiments, the squeeze-type washing machine 5 having two push-pull seats 51 is described, but the present invention is not limited thereto. The squeeze-type washing machine 5 of the present invention may also have three or more push-pull seats 35. In the first to third embodiments, the push-pull seats in the shape of a rectangular parallelepiped are described, but the present invention is not limited thereto. In the squeeze-type washing machine 5 of the present invention, the push-pull seats may have any shape and size.

[0070] In the first embodiment, the two push-pull seats 51 are respectively arranged on the left and right sides of the box body 5a when viewed from the front, and in the second embodiment, the two push-pull seats 51 are respectively arranged on the front side and the back side of the box body 5a when viewed from the side, but the invention is not limited thereto. In the squeeze-type washing machine 5 of the present invention, the arrangement of the plurality of push-pull seats 51 is arbitrary.

[0071] In the first embodiment, only the position detection switches 65a and 65b for detecting the position of one of the two push-pull seats 51 are arranged inside the box 5a, but a position detection switch for sensing the position of the other of the two push-pull seats 51 may also be arranged. In this case, the positions of the two push-pull seats 51 are respectively detected by the position detection switches.
