Description

  The present invention relates to a washing machine.

  For example, Patent Document 1 describes a washing machine in which the opening of the upper surface of the water tank elastically supported in the outer case is closed by a tank cover having an opening at the center and the opening is opened and closed by an inner lid. . In the washing machine of patent document 1, the handle rotated by the inner cover is provided. The handle is provided with a hook member having a claw. When the inner lid is closed, the hooks of the hook member engage with the hooks of the locking member provided on the tank cover side, and the inner lid is held closed.

  Thus, in order to hold the inner lid in the closed state, when the structure by the claw portion is adopted, the structure of the claw portion is exposed to the outside when the inner lid is opened, and the inside is opened. When the user looks at the lid, it does not necessarily look good.

  Therefore, in order to improve the appearance of the inner lid, it is conceivable to use a magnet and to adopt a structure in which the inner lid is held closed by the attraction force of the magnet.

  For example, Patent Document 2 describes that in a washing machine, a magnet is used to hold a closure of a lid in a detergent supply device.

JP, 2010-200943, A JP 2005-514133 A

  When a magnet is used for closing and holding the lid of the detergent supply device as in Patent Document 2, the user may easily open and close the lid without a problem because the adsorption power may be weak.

  On the other hand, a large force is likely to be applied to the inner lid in the opening direction due to the vertical vibration of the water tank which may occur during dehydration and the collision of the laundry with the inner lid which may occur during washing. For this reason, when a magnet is used to close and hold the inner lid, a strong attractive force is required. Therefore, in this case, there is a concern that it is difficult for the user to perform the opening / closing operation.

  Therefore, the present invention provides a washing machine that allows the user to easily open and close the outer tub lid when the outer tub lid covering the opening of the upper tub surface is closed and held by a structure using a magnet. With the goal.

  The washing machine according to the main aspect of the present invention comprises an outer tub elastically supported in a housing, a washing and dewatering tub rotatably disposed in the outer tub and containing a laundry, and the outer tub. And an outer tub lid closing an opening provided on the upper surface. Here, the outer tub lid has a first rotation axis at one end thereof, and is opened and closed by rotating around the first rotation axis with respect to the outer tub, and the other end portion is opened and closed. It has a handle rotatable about a second rotation axis parallel to the first rotation axis. The handle includes a first arrangement surface facing the upper surface of the outer tank in a state where the outer tank lid closes the opening, and a first suction surface arranged in the first arrangement surface; And a hand hook portion which is provided to be separated from the first suction surface in a direction in which the first rotation axis and the second rotation axis are arranged, and which can be hung by a user's hand. The upper surface of the outer tank is arranged in a second arrangement surface corresponding to the first arrangement surface and in the second arrangement surface, and the first tank is in a state where the outer tank lid closes the opening. And a second suction surface in contact with the second suction surface. One of the first adsorption surface and the second adsorption surface generates a magnetic force by the magnet, and the other surface is attracted to the one surface by the generated magnetic force. When the handle portion is lifted in a state where the outer tank lid closes the opening, a fulcrum is located at a position opposite to the handle portion across the first suction surface in the first arrangement surface. The first arrangement surface rotates around the fulcrum, and the first adsorption surface separates from the second adsorption surface.

  According to the above configuration, according to the principle of leverage with the hand portion as the power point and the contact area of the first suction surface with the second suction surface as the action point, the first suction surface is the second suction surface It can be easily pulled away. Thus, the user can easily open and close the outer tub lid.

  In the washing machine according to the present aspect, the second arrangement surface is configured to be higher than the upper surface of the outer tub, and the first arrangement surface is opposite to the direction of the hook portion. A configuration may be adopted in which a space is formed between the protruding surface portion and the upper surface of the outer tank, which is more projecting than the second disposition surface.

  According to the above configuration, since the fulcrum can be formed not on the end of the first arrangement surface but on a portion close to the first adsorption surface in the first arrangement surface, the first action point from the fulcrum is The distance to the contact area of the suction surface can be shortened. As a result, a large upward force is likely to be applied to the contact area of the first suction surface, and the first suction surface can be further easily separated from the second suction surface.

  When it is set as said structure, it protrudes on the upper surface side of the said outer tank on the said 1st arrangement | positioning surface on the opposite side to the said hook part with respect to the said 1st adsorption surface, and becomes the said fulcrum A protrusion may be provided. In this case, the upper surface of the outer tank is provided with an inclined surface which is lowered to the space side so as to continue from the second arrangement surface and in contact with the projection.

  When the handle pivots due to the lifting of the handle, the second rotary shaft moves upward accordingly, and the outer tub lid pivots about the first rotary shaft and opens slightly. When the outer tub lid opens, a force is applied to the handle to pull the handle horizontally. In the above configuration, when the handle is pulled in the horizontal direction, the inclined surface is pushed in the horizontal direction by the protrusions, and the horizontal force is converted into an upward force to act on the protrusions. As a result, the protrusion rises along the inclined surface, and the handle pivots at the same time as the handle rotates, so that the first suction surface can be more easily pulled away from the second suction surface.

  When it is set as said structure, the said projection part can be further set as a structure which has a surface parallel to the said inclined surface.

  With such a configuration, the parallel surfaces of the projections substantially contact the inclined surface, so that the inclined surface can be favorably pushed backward by the projections, and the upward conversion converted by the inclined surface is possible. A sufficient force can be applied to the protrusions. As a result, the handle can be easily lifted, and the first suction surface can be further easily separated from the second suction surface.

  When it is set as said structure, the front-end | tip part of the said projection part may have R shape further.

  With such a configuration, when the rotation of the handle proceeds, the tip end portion is less likely to be caught on the inclined surface, and the handle can be rotated smoothly.

  In the washing machine according to the present aspect, the one surface may be configured by the surface of the magnet. In this case, the other surface is constituted by the surface of the magnetic body.

  According to said structure, a 1st adsorption | suction surface and a 2nd adsorption | suction surface can be adsorbed strongly, and an opening part can be obstruct | occluded strongly by an outer tank cover.

  According to the present invention, the user can easily open and close the outer tub lid when the outer tub lid covering the opening of the outer tub upper surface is closed and held by the structure using the magnet.

  The effects and significances of the present invention will become more apparent from the following description of the embodiments.

  FIG. 1 is a side sectional view of a full-automatic washing / drying machine 1 according to the present embodiment. FIG. 2 is a rear perspective view of the upper part of the full-automatic washing / drying machine 1 according to the present embodiment.

  The fully automatic washing / drying machine 1 is provided with a housing 10 constituting an appearance. The housing 10 includes a rectangular cylindrical body portion 11 whose upper and lower surfaces are open, an upper surface plate 12 covering the upper surface of the body portion 11, and a footrest 13 for supporting the body portion 11. The upper surface plate 12 is formed with an outer insertion port 14 for inserting the laundry. The outer inlet 14 is covered by an openable upper lid 15.

  In the housing 10, the outer tub 20 is elastically suspended and supported by four suspension rods 21 having a vibration isolation device. The outer tank 20 includes a substantially cylindrical outer tank main body 22 whose upper surface is open, and an outer tank cover 100 which covers the upper surface of the outer tank main body 22 to constitute the upper surface of the outer tank 20. On the upper surface of the outer tub 20, that is, on the outer tub cover 100, an inner loading slot 101 for loading the laundry is formed at a position corresponding to the outer loading slot. The inner charging port 101 is covered by an outer tub lid 23 so as to be openable and closable.

  In the outer tank 20, a substantially cylindrical washing and dewatering tank 24 whose upper surface is opened is disposed. On the inner circumferential surface of the washing and dewatering tank 24, a large number of dewatering holes 24a are formed over the entire circumference. A balance ring 25 is provided at the top of the washing and dewatering tank 24. A pulsator 26 is disposed at the bottom of the washing and dewatering tank 24. A plurality of blades 26 a are provided radially on the surface of the pulsator 26.

  At an outer bottom portion of the outer tank 20, a drive unit 30 for generating a torque for driving the washing and dewatering tank 24 and the pulsator 26 is disposed. The drive unit 30 includes a drive motor 31 and a transmission mechanism portion 32. The transmission mechanism section 32 has a clutch mechanism, and in the washing process and the rinsing process, the torque of the drive motor 31 is transmitted only to the pulsator 26 to rotate only the pulsator 26 by the switching operation by the clutch mechanism. The torque of the drive motor 31 is transmitted to the pulsator 26 and the washing and dewatering tank 24 to rotate the pulsator 26 and the washing and dewatering tank 24 integrally.

  A drainage port 20 a is formed at the outer bottom of the outer tank 20. A drainage valve 40 is provided at the drainage port 20a. The drain valve 40 is connected to the drain hose 41. When the drain valve 40 is opened, the water stored in the washing and dewatering tank 24 and the outer tank 20 is drained out of the machine through the drain hose 41.

  The drying device 50 and the water supply device 60 are disposed above the outer tank 20 at the rear of the housing 10. The drying device 50 and the water supply device 60 are attached to a fixing plate 16 disposed at the rear of the upper surface of the body portion 11 and covered by the upper surface plate 12.

  The drying device 50 dries the laundry stored in the washing and dewatering tank 24. The drying device 50 includes a circulation air passage 50 a in which a heater and a blower fan are disposed, and the circulation air passage 50 a is connected to the inside of the outer tub 20 by an intake duct 71 and an exhaust duct 72. The intake duct 71 and the exhaust duct 72 are flexible ducts, are formed of an elastic material such as rubber, and have a bellows portion (not shown) in the middle portion. The warm air generated by the operation of the heater and the blower fan is discharged from the circulation air passage 50 a and introduced into the outer tank 20 through the air intake duct 71. Further, the warm air discharged from the outer tank 20 is introduced into the circulation air passage 50 a through the exhaust duct 72. Thus, warm air circulates between the circulation air passage 50 a and the outer tank 20.

  The drying device 50 performs a circulation drying operation by circulation of warm air, and an exhaust drying operation to discharge a part of the circulating warm air to the outside. The upper surface plate 12 is provided with a large number of exhaust holes, and is provided with an exhaust port 51 through which warm air is discharged.

  In the water supply device 60, a water supply port 61 exposed to the outside is connected to an external water supply hose (not shown) extending from a water faucet. The water supply device 60 includes a water supply valve and a detergent container, and when the water supply valve is opened, tap water from the faucet is supplied into the outer tub 20 together with the detergent contained in the detergent container. The water supply device 60 may include a bath water pump.

  In the fully automatic washing and drying machine 1, washing operation, washing and drying operation, or drying operation of various operation courses are performed. The washing operation is an operation of performing only washing, and a washing step, an intermediate dewatering step, a rinsing step and a final dewatering step are sequentially performed. The washing and drying operation is an operation that continuously performs from washing to drying, and the drying step is performed subsequent to the final dewatering step. The drying operation is an operation of performing only drying, and only the drying step is performed.

  In the washing step and the rinsing step, with the water stored in the washing and dewatering tank 24, the pulsator 26 rotates rightward and leftward. The rotation of the pulsator 26 generates a water flow in the washing and dewatering tank 24. In the washing step, the laundry is washed with the generated water stream and the detergent contained in the water. In the rinsing step, the generated water stream rinses the laundry.

  In the intermediate dewatering process and the final dewatering process, the washing and dewatering tank 24 and the pulsator 26 rotate together at high speed. The laundry is dewatered by the action of the centrifugal force generated in the washing and dewatering tank 24.

  In the drying step, an internal air circulation drying step is performed first, followed by an open air introduction drying step. In the inside air circulation drying step, the circulation drying operation is performed by the drying device 50, and the warm air is circulated between the circulation air passage 50a and the outer tank 20. The circulation of the drying wind quickly raises the temperature in the washing and dewatering tank 24. The pulsator 26 is rotated, and the laundry is agitated and dried by the circulating hot air. When the temperature rise in the washing and dewatering tank 24 progresses and the moisture evaporates from the laundry and the hot air contains a large amount of moisture, the process is switched to the outside air introducing and drying process. In the outside air introduction and drying step, the drying device 50 performs an exhaust air drying operation to introduce outside air into the circulation air passage 50a and exhaust a part of the warm air circulating from the circulation air passage 50a. Since the water evaporated from the laundry is effectively discharged from the inside of the outer tank 20 to the outside of the housing 10 and the inside of the outer tank 20 is easily dehumidified, drying of the laundry is promoted.

  Next, the opening and closing operation of the outer tank lid 23 will be described.

  Fig.7 (a) is sectional drawing of the principal part of the outer tank cover 100 and the outer tank lid 23 by which the periphery of the handle 300 in the state with which the outer tank lid 23 was closed based on this Embodiment was shown, FIG.7 (b) shows the essentials of the outer tank cover 100 and the outer tank lid 23 by which the periphery of the handle 300 in the state which rotated the handle 300 in order to open the outer tank lid 23 based on this Embodiment was shown. It is sectional drawing of a part. 7 (a) and 7 (b), the packing 230 in a non-crushed state is shown, but in fact, the packing 230 is crushed and is in contact with the surface of the outer tub cover 100. .

  As shown in FIG. 7A, when the outer tub lid 23 is closed and the inner feeding port 101 is closed by the outer tub lid 23, the handle-side suction surface 322 of the handle 300 is on the outer tub side of the outer tub cover 100. The handle-side attraction surface 322 is attracted to the outer-tank-side attraction surface 161 by the magnetic force of the magnet 160 generated by the outer-tank-side attraction surface 161 in contact with the attraction surface 161. Here, the adsorption force between the handle side adsorption surface 322 and the outer tank side adsorption surface 161 is stronger than the elastic force of the packing 230, and the outer tank lid at the time of vertical vibration or washing of the outer tank 20 at the time of dehydration. The impact of the laundry on 23 may be a force higher than the upward force that can be generated on the outer tub lid 23.

  The handle side disposition surface 335 projects forward of the outer tank side disposition surface 151, that is, in the direction opposite to the handle portion 315 of the handle 300, and the projected surface portion and the outer tank cover 100, ie, the upper surface of the outer tank 20. Space S is formed. Furthermore, the handle-side inclined surface 337 of the projection 336 provided on the handle-side arrangement surface 335 is parallel to and substantially in contact with the outer tank-side inclined surface 152.

  When the outer tub lid 23 is opened, the user places a finger on the handle portion 315 of the handle 300 and lifts the handle portion 315 obliquely upward and forward. As shown in FIG. 7B, when the handle portion 315 is lifted, the handle-side inclined surface 337 of the projection 336 contacts the outer tank-side inclined surface 152 and the handle 300 rotates forward with the projection 336 as a fulcrum. Move. Thereby, the handle side disposition surface 335 rotates, and the handle side suction surface 322 is pulled away from the outer tank side suction surface 161. At this time, the handhold portion 315 is a force point, the projection portion 336 is a fulcrum, and the contact area of the handle side suction surface 322 with the outer tank side suction surface 161 is an action point, and the contact region of the handle side suction surface 322 according to the principle of leverage. The handle-side suction surface 322 is likely to be pulled away from the outer tank-side suction surface 161 because a large upward force is exerted.

  When the handle 300 rotates forward, the handle rotation axis R2 moves upward along with it, and the lid body 200, that is, the outer tub lid 23 rotates around the lid rotation axis R1 and moves upward. Then open slightly. When the outer tub lid 23 is pivoted, the handle rotation axis R2 is moved not obliquely upward but obliquely upward rearward, so that a force to pull the handle 300 backward is applied to the handle 300. In the handle 300, since the projection 336 is in contact with the outer tank side inclined surface 152, the outer tank side inclined surface 152 is pushed backward by the projection 336 and converted to an upward force of this rearward force. It will act on the projection 336. As a result, the protrusion 336 ascends along the outer tank side inclined surface 152 and ascends as the handle 300 pivots, so the handle side suction surface 322 is more easily pulled away from the outer tank side suction surface 161. .

  Here, the protrusion 336 is formed with a handle-side inclined surface 337 parallel to the outer tank-side inclined surface 152, and when the protrusion 336 first contacts the outer tank-side inclined surface 152, the handle-side inclined surface 337 substantially contacts the outer tank side inclined surface 152. Therefore, the outer tank side inclined surface 152 can be favorably pushed backward by the handle side inclined surface 337, and the upward force converted by the outer tank side inclined surface 152 is favorably applied to the projection 336. Further, when the handle 300 rotates forward, the tip 338 of the projection 336 comes in contact with the outer tank side inclined surface 152. The tip portion 338 of the projection 336 has an R shape, so it is difficult to be caught on the outer tank side inclined surface 152, and the handle 300 rotates smoothly.

  When the handle side suction surface 322 is pulled away from the outer tank side suction surface 161, the user rotates the outer tank lid 23 backward while holding the handle 300 to largely open the outer tank lid 23. Thereby, the inner insertion port 101 is opened.

<Effect of the embodiment>
As described above, according to the present embodiment, the protrusion 336 is the fulcrum, the hand grip 315 is the force point, and the contact area of the handle side suction surface 322 with the outer tank side suction surface 161 is the action point. The handle side suction surface 322 can be easily pulled away from the outer tank side suction surface 161. Thereby, the user can easily perform the open / close operation of the outer tank lid 23.

  Further, according to the present embodiment, since the space S is formed between the handle side disposition surface 335 and the outer tub cover 100 in front of the handle side suction surface 322, the front end portion of the handle side disposition surface 335 Instead, the protrusion 336 which is a fulcrum can be formed in a portion near the handle-side suction surface 322 in the handle-side arrangement surface 335. Thus, the distance from the projection 336 serving as the fulcrum to the contact area of the handle-side suction surface 322 serving as the point of action can be shortened, so that a large upward force is likely to be applied to the contact area of the handle-side suction surface 322. Therefore, the handle side suction surface 322 can be further easily separated from the outer tank side suction surface 161.

  Furthermore, according to the present embodiment, the protrusion 336 is in contact with the outer tank side inclined surface 152 when the handle 300 is rotated, and the handle 300 generated when the handle 300 is rotated is moved backward. Since the force is converted into an upward force and acts on the projection 336, the projection 336 can be raised along the outer tank side inclined surface 152, and at the same time the handle 300 is rotated. It can be raised. As a result, the handle side suction surface 322 can be more easily pulled away from the outer tank side suction surface 161.

  Furthermore, according to the present embodiment, the outer tank side inclined surface 152 is formed by the handle side inclined surface 337 by bringing the handle side inclined surface 337 formed in the projection 336 into substantially surface contact with the outer tank side inclined surface 152. It can be pushed well backward, and the upward force converted by the outer tank side inclined surface 152 can be sufficiently applied to the projection 336. As a result, the handle 300 can be easily raised, and the handle-side suction surface 322 can be further easily separated from the outer tank-side suction surface 161.

  Furthermore, according to the present embodiment, since the tip end portion 338 of the projection 336 is rounded, the tip portion 338 is formed on the outer tank side inclined surface 152 when the handle 300 moves forward. The handle 300 can be rotated smoothly.

  Furthermore, according to the present embodiment, the handle-side suction surface 322 is formed by the lower surface of the suction bracket 320, and the outer tank-side suction surface 161 is formed by the upper end surface 160a of the magnet 160. Since the magnet 160 and the magnet 160 are in direct contact with each other, the handle side suction surface 322 and the outer tank side suction surface 161 can be strongly adsorbed. Therefore, the inner charging port 101 can be firmly closed by the outer tank lid 23.

  As mentioned above, although the embodiment of the present invention was described, the present invention is not limited at all by the above-mentioned embodiment etc. In addition, the embodiment of the present invention can be variously modified in addition to the above. is there.

  For example, in the above embodiment, a configuration is adopted in which the suction fitting 320 and the magnet 160 are in direct contact with each other. However, as shown in FIG. 8A, by not providing the opening 334 in the bottom wall surface part 331 of the metal fixture holder 330 and covering the upper end surface 160 a of the magnet 160 with the cover 154, the suction metal fitting 320 is obtained. A configuration may be adopted in which the magnet and the magnet 160 do not directly contact with each other. In this case, the projection range of the lower surface of the adsorption bracket 320 on the outer surface of the bottom wall portion 331 of the bracket holder 330 is the handle side adsorption surface 322, and the projection range of the upper end surface 160a of the magnet 160 on the upper surface of the cover 154 is outer tank adsorption It becomes the surface 161. Alternatively, the bottom wall surface portion 331 of the metal fitting holder 330 may be provided with the opening 334, and the top end surface 160a of the magnet 160 may be covered with the cover 154. A configuration may be adopted in which the opening 334 is not provided and the upper end surface 160 a of the magnet 160 is not covered by the cover 154. When configured as described above, it is desirable to make the magnetic force of the magnet 160 stronger than the magnetic force in the above embodiment.

  Moreover, in the said embodiment, the magnet 160 was arrange | positioned at the outer tank cover 100 side, and the adsorption metal fitting 320 was arrange | positioned at the handle 300 side. However, as shown in FIG. 8 (b), the suction fitting 170 may be disposed on the outer tank cover 100 side, and the magnet 340 may be disposed on the handle 300 side. In this case, the lower end surface of the magnet 340 is the handle side suction surface 341, and the upper surface of the suction fitting 170 is the outer tank side suction surface 171.

  Furthermore, in the above embodiment, an example is shown in which the present invention is applied to a fully automatic washing and drying machine 1 equipped with a drying function of clothes. However, the present invention can also be applied to a fully automatic washing machine in which the drying function of the clothes is not installed, as long as the outer tank lid 23 covering the inner charging port 101 on the upper surface of the outer tank 20 is provided.

  Besides the above, the embodiment of the present invention can be variously modified as appropriate within the scope of the technical idea shown in the claims.
