An intermediate housing 50 is formed between the cover 40 and the cover 40. Inside the main housing 20, the washing tub 10 whose upper part is covered with a laundry opening / closing lid 101 is attached via a plurality of hanging rods 201.
As shown in FIG. 3, a rotating tub 80 and a pulsator 850 are coaxially and rotatably mounted in the washing tub 10 via a drive motor 201 provided at the lower portion of the washing tub 10. Since the upper part of the rotating tank 11 is opened and the two opening / closing lids are opened, the opening part of the rotating tank 11 is formed so as to be continuous with the clothing input port 60. The clothes can be taken in and out of the rotary tank 80. In this embodiment, by providing the drying unit 202 on the back side of the washing tub 10, the clothes put into the rotating tub 80 can be washed, dehydrated, and dried by warm air.

  Returning to FIG. 1, one of the features of this embodiment is that a large operation panel 900 is provided on the opening / closing lid 70. In this embodiment, the opening / closing lid 70 includes a front opening / closing lid 710 that covers the front portion of the clothing insertion port 60 and a rear opening / closing lid 720 that covers the rear portion of the clothing insertion port 60. The member is provided so as to be foldable via the first connecting portion 750, and the operation panel 900 is provided on the front opening / closing lid 710. With this configuration, it is possible to arrange large operation switches having good operability using the wide opening / closing lid 70. In addition, since it is not necessary to form a space for arranging the operation switches around the clothing input port 60, the clothing input port 60 can be formed large on the upper surface of the housing 20.

  One of the additional features is that, using the support rails 601 provided on both sides of the garment insertion port 60, the front end of the front opening / closing lid 710 whose weight is increased by the substrate of the operation panel 900 or the like (free End) Q1 can be supported.

In this embodiment, a handle portion 730 is provided adjacent to the first connecting portion 750. As a result, the user can open the opening / closing lid 70 by pulling the first connecting portion 750 upward via the handle portion 730, and the weight of the opening / closing lid 70 can be reduced. Since the second connecting portion 760 of the end portion Q2 and the free end Q1 are dispersed and supported, it is possible to reduce unnecessary loads caused by opening and closing of the user. In addition, in this embodiment, by providing the power switch 950 separated and independent from the operation panel 900 at the front portion of the casing 20, various operations can be performed even when the opening / closing lid 70 is opened. .

  Further, one of the additional features is that the upper cover 30 that can be seen from the outside is formed into a thin plate, and this thin plate is inclined from the rear to the front of the main housing 20 and has a large roundness at the front. Thus, the shape is continuous with the front portion of the intermediate casing 50. In the conventional structure, since the lower end portion of the upper cover is formed in a horizontal plane, the side shape of the upper cover is generally a wedge shape with a thick rear portion and a thin front portion. In the embodiment, the upper cover 30 is formed in such a shape that the inclined end surface 501 is covered with a thin plate material by forming the upper end surface 501 of the intermediate housing 50 to be an obliquely inclined upper end surface 501 having a high rear portion and a low front portion. Thereby, a new appearance structure can be taken also in terms of design, and since there are few wide planes, sink marks and the like are hardly generated (not noticeably), and molding defects can be reduced.

  Further, as shown in FIG. 2, one of the additional features is that the height H1 from the floor surface of the corners 502 on both sides of the front of the intermediate casing 50 is set to the corners on both sides of the rear of the intermediate casing 50. The portion 503 is formed to be lower than the height H2 from the floor surface, the front suspension rod attachment portions 504 are provided at the corner portions 502 on both sides of the front portion, and the rear suspension rod attachment portions 505 are provided at the corner portions 503 on both sides of the rear portion.

According to this structure, the above-described new external shape can be realized, and the height from the floor surface at the front portion of the clothing insertion port 60 to the height from the floor surface at the rear portion of the clothing drying washing machine 1 can be increased. Can be lowered without lowering. Thereby, taking in / out of the clothes insertion port 60 becomes easy. In particular, in this embodiment, since the operation board provided at the front portion of the garment input port 60 is provided on the opening / closing lid 70, the height of the garment input port 60 from the floor surface can be further reduced. Therefore, clothes can be taken in and out of the clothes insertion port 60 in a good manner.

  Moreover, as shown in FIG. 3, one of the further features is that the height H3 from the floor surface of the lower case 40 is formed high. In this embodiment, since the upper end surface of the intermediate casing 50 is extended to the upper position, the front and rear lengths of the intermediate casing 50 are increased. However, as the length of the intermediate casing 50 increases, the parts become larger, and measures such as remodeling of the production line and increasing the strength are required. Therefore, in this embodiment, the problem is solved by increasing the height H3 of the lower case 40 from the floor surface. And by forming this height H3 high, the circulation pump 401, the circulation filter 402, and the blower fan 403 shown in FIG. 6 can be accommodated in the increased internal volume of the lower case 40.

  Further, one of the features is that the pulsator 850 that allows the clothes to be washed by vibrating the clothes in the rotary tank 80 up and down is adopted. The pulsator 850 has a circular upper surface shape, and its surface is composed of a plurality of raised portions 851 formed radially from the rotation axis P and valleys 852 formed between the raised portions 851.

  7 and 8, the side cover 302 is formed to be detachable from the base cover 301. This is a structure that solves the molding problem of the support rail 601. That is, since the support rail 601 is formed on a vertical surface, a complicated mold is required to form the support rail 601 by resin molding. In this embodiment, paying attention to the fact that the support rail 601 is formed along the inclined surface of the upper case 30, the upper portion of the support rail 601 is constituted by a separate side cover 302. According to this embodiment, assembling can be improved by using the side cover 302 as a separate member. In this embodiment, the water supply port mounting surface 303 is a separate member that can be separated from the base cover 301. For this reason, since the paint colors of the side cover 302 and the base cover 301 can be made different from those of the other base cover 301 portions, color development at an implementation level can be achieved.

  In this embodiment, the side cover 302 is provided on the support rail 601, but a groove is formed in the base cover 301 portion inside the side cover 302, and this groove is supplied to the detergent charging unit 605. It can be used as a piping space for wiring and a wiring space for wiring to the power switch.

  On the other hand, in this embodiment, the outer shape of the upper cover is inclined from the rear to the front, and the cylindrical inlet 603 is formed at the lower part of a thin plate-like member whose front portion is formed with a large roundness. Has a shape projecting downward. A wide space 606 is formed behind the cylindrical inlet 603. In other words, a plate-like upper surface portion protrudes behind the insertion port 603. That is, in this embodiment, since the peripheral side surface which is continuous with the upper surface of the upper cover 30 is hardly formed, a wide space 606 opened below the rear portion of the upper case 30 is formed, and the heater portion is formed in the space 606. 308, a bath water pump 309, a water supply valve 310, and other internal components are attached.

  Since the conventional upper cover has a peripheral side surface continuous with the upper surface, when attaching an internal part to the upper cover, the upper cover is inverted and the internal part is attached to the bottom of the upper cover. For this reason, when attaching an internal component, the surrounding peripheral side surface got in the way and hindered assembly. Particularly, since these internal parts are attached to the rear part of the upper cover having a large front and rear height, the height of the peripheral side surface is also increased, and the above-mentioned problem is also increased. In this respect, in this embodiment, since there are almost no peripheral side surfaces, the internal parts can be attached to the open space 606, so that the assemblability can be improved.

  In this embodiment, a water supply valve 310 for attaching a water faucet is provided on the left side of the large space 606, a heater unit 308 is provided on the right side, and a bath water pump 309 is provided between the heater unit 308 and the water supply valve 310. Is prepared. Note that the hot air filter 305 is inserted from a cylindrical inlet 603 below the water supply valve 310.

  Further, as described above, since the upper cover 30 according to this embodiment has a structure without the peripheral side surface as referred to in the prior art, in the state in which the upper cover 30 is attached to the intermediate casing 50, the cylinder The shape of the slot 603 is almost the same as the inner volume of the intermediate casing 50. In this embodiment, the insertion port arrangement surface 602 is also configured to be accommodated in the inner volume of the intermediate casing 50. For this reason, since most of the upper cover 30 is housed in the intermediate housing 50, the design of the thin upper cover 30 can be made stronger.

  In this embodiment, a plurality of hook ribs 311 are provided on both side surfaces of the cylindrical inlet 603. The hook rib 311 is for holding piping for supplying water to the detergent charging unit 605 and wiring to the power switch. In this embodiment, since the hook rib 311 can be exposed by eliminating the peripheral side surface of the upper cover 30, the assemblability can be greatly improved.

  Although not adopted in this embodiment, the hook rib 311 can be used for positioning the upper cover 30 and the intermediate housing 50. For example, the tip of the hook rib 311 is in contact with the inner wall surface of the intermediate housing 50. According to this structure, when the lower part of the upper cover 30 is inserted into the intermediate housing 50 at the stage where the internal parts are attached to the upper cover 30, the hook ribs provided on both sides of the insertion port 603 are used. Since the front end portion of 311 contacts the inner wall surface of the intermediate casing 50, the positional relationship between the upper cover 30 and the intermediate casing 50 is specified. Then, by inserting the lower portion of the upper cover 30 into the intermediate casing 50 as it is, the overhanging portion 304 protruding around the upper cover 30 is supported by the upper end surface 501 of the intermediate casing 50. The cover 30 can be attached to a predetermined position of the intermediate housing 50 via a screw or the like (not shown).

Next, with reference to FIG. 6 and FIG. 9, a warm air supply and a water supply path are demonstrated. FIG. 9 schematically shows the water supply path.

One is a first duct 204 whose lower end is connected to the washing tub 10, and the other is a second duct 205 whose upper end is connected to the upper end of the first duct 204; The other one is a third duct 206 having a lower end connected to the second duct 205 and an upper end connected to the heater unit 308. The first duct 204 includes a heat exchange plate (not shown) that dehumidifies the air taken in from the washing tub 10, and a blower fan 403 is provided at the lower ends of the second and third ducts 204 and 205. Note that the hot air filter 305 is inserted into the ventilation path at the upper end of the first duct 204 to remove lint and the like contained in the hot air during drying.

  According to this embodiment, air in the washing tub 10 can be taken into the drying unit 202 through the blower fan 403 during drying. Air taken in from the lower part of the washing tub 10 is dehumidified through the heat exchange plate while rising through the first duct 204. Then, the air rising through the first duct 204 descends again through the second duct 205 and enters the blower fan 403, and then rises through the third duct 206 and is taken into the heater unit 308. And warm air. By the duct meandering up and down, water that has entered the first duct 204 by mistake can be prevented from entering the second duct 205 provided with the blower fan 403. Further, according to this structure, the upper case 30 can be provided in the lower case 40 having a sufficient space without providing the blower fan 403 in the upper case 30, so that the size of the upper case 30 can be made compact. The hot air discharged from the drying unit 202 is supplied into the washing tub 10 through the washing tub water supply port 106 at the upper part of the washing tub 10.

  In FIG. 9, in this embodiment, by adopting a corrugated pulsator 850, the amount of water during washing can be greatly reduced. For example, according to the experimental verification of this embodiment, it is possible to obtain a good cleaning effect as a tapping wash with an amount of water enough to immerse clothes put in the rotary tub 80. In this embodiment, in order to obtain a better cleaning effect, a circulation pump 401 is provided in the lower case 40, and a small amount of water is sprinkled on the clothes with the circulation pump 401 to improve the cleaning efficiency and the rinsing efficiency. It is increasing.

  That is, when water is supplied during washing, the water supplied from the faucet is adjusted by the water supply valve 310 and supplied into the washing tub 10 from the washing tub water supply port 106 at the top of the washing tub 10. Water is supplied into the rotary tank 80 in the form of a shower from the inner wall surface of 101. The bath water supplied from the bath water pump 309 is also supplied into the washing tub 10 from the washing tub water supply port 106 at the upper part of the washing tub 10, and is supplied in the form of a shower from the inner wall surface of the laundry opening / closing lid 101 into the rotary tub 80. The The water supply valve 310 also supplies water to the detergent charging unit 605, and the detergent charging unit 605 liquefies the detergent (such as powdered soap) and supplies it to the washing tub 10.

  In addition, when washing is too easy, the circulation pump 401 is used to enable washing and rinsing at a low water level. In the prior art, it was not necessary to use the circulation pump 401 in order to perform washing and rinsing with the amount of water of the washing tub 10. However, if the circulation pump 401 is not used at a low water level, it is difficult to supply water taken from the lower portion of the washing tub 10 from the washing tub water supply port 106 of the laundry opening / closing lid 101. In this embodiment, this is achieved by providing the circulation pump 401 in the lower case 40 at a low position.

In addition, when such a circulation method is employed, if waste thread is mixed into the circulating water, it may cause a failure of the circulation pump 401 or the like. Therefore, in this embodiment, a circulation filter 402 that removes lint is provided in the circulation path. When this circulation filter 402 is provided, it is necessary to provide it before the circulation pump 401. However, in this embodiment, the circulation pump 401 is provided in the lower lower case 40, so that the attachment position of the circulation filter 402 is provided. Is in a low position.
However, in this embodiment, the overall height of the lower case 40 is increased, and a large opening can be obtained by removing the front cover 405 and the maintenance lid 407 covering the front surface of the lower case 40 having this height.

In the rear portion of the housing, the arrangement space for the heater unit 308, the bath water pump 309, and the water supply valve 310 is improved. Is secured. Further, by arranging the large operation panel 900 on the inclined surface, the operability with the finger of the user in the standing posture is improved.

  Furthermore, in this embodiment, the operation panel 900 is provided on the front opening / closing lid 710 so that the opening / closing lid 70 can be operated in a closed state or an open state. In this embodiment, since the folding door is folded in two, the operation panel 900 is provided on the front opening / closing lid 710 so that the user's side is closed when the opening / closing lid 70 shown in FIG. 10 is closed. The operation panel 900 can be positioned on an inclined surface close to, and in the closed state shown in FIG. 11, the operation panel 900 can be positioned on an inclined surface that inclines and rises toward the user side.

  On the other hand, in the case of the two-fold open / close lid, it is also an important factor to smoothly open and close the open / close lid 70. In this embodiment, in order to improve the opening / closing operation, the handle portion 730 is provided at the rear center portion of the front opening / closing lid 710 so as to hold the vicinity of the first connecting portion 750. . The handle portion 730 is formed in a concave shape, and is provided with a handle portion 731 for hooking the near side of the concave portion with a finger.

  In this embodiment, by providing the operation panel 900 continuously in front of the handle portion 730, the opening / closing operation of the opening / closing lid 70 and the operability and visibility of the operation panel 900 can be improved. it can. That is, when the operation panel 900 is provided on the opening / closing lid 70, the weight of the operation board and the like is inevitably increased as compared with the case where the operation panel 900 is not provided. However, in this embodiment, since the vicinity of the first connecting portion 750 is held, the burden on the user can be reduced. Further, in this embodiment, since the operation panel 900 can be provided on the front side of the handle portion 730, the operation panel 900 is brought close to the user when the opening / closing lid 70 is closed, and is closed when it is opened. Since the operation panel 900 can be positioned without greatly changing the position, it is possible to reduce the large change in the operational feeling in the two states. Moreover, since the handle portion 730 and the operation panel 900 can be formed as one lump, the design can be improved.

  Further, in this embodiment, in order to make the entire apparatus compact, the front upper portion of the main housing 20 has a large round shape. In addition, the front end portion (free end) Q1 of the opening / closing lid 70 has a front hanging shape in accordance with the round shape. As a result, when the opening / closing lid 70 is closed, the opening / closing lid 70 is formed in a compact and soft form that is continuous with a large round on the front panel 510 of the intermediate casing 50 formed with a vertical surface.

On the other hand, in the state in which the opening / closing lid 70 shown in FIG. 11 is opened, the garment insertion port 60 that is one step lower than the side cover 302 is formed so as to be pulled forward, so the front portion of the garment insertion port 60 can be lowered. Clothes can be taken in and out.
Furthermore, by opening and forming the front end (free end) Q1 of the opening / closing lid 70, the opening / closing operation, the enlargement of the bowl-shaped insertion port 603, and the operation with the opening / closing lid 70 opened are performed. The operability of the panel 900 can be improved. This will be described in detail with reference to FIGS.

In this embodiment, the power switch 950 is provided separately from the operation panel 900. In this embodiment, a concave groove 524 is formed between the front end portion (free end) Q1 of the opening / closing lid 70 and the intermediate casing 50, and the ON / OFF switch is provided on one side of the concave groove 524. Is arranged.
In this embodiment, the operation panel 900 is formed by a small-stroke sheet switch disposed on the substrate, and is not suitable for a power switch that requires a reliable operation with a large stroke. Further, if a robust power switch is provided on the opening / closing lid 70 with a robust wiring, the weight is increased.

  Thus, in this embodiment, the power switch 950 is provided in the concave groove 524 to solve the problem. When the opening / closing lid 70 is closed, the concave groove 524 is covered with the front end portion (free end) Q1 so that an erroneous operation is unlikely to occur. Moreover, in the state which opened the opening-and-closing lid | cover 70, since the upper part is open | released, it does not cause trouble in cleaning property and operativity.

  In this embodiment, by adopting the above structure, as is apparent from the side view, the side plate of the intermediate casing 50 is extended upward, and the upper cover 30 is formed in a thin plate shape when viewed from the side. doing. The thin plate shape is formed so as to be continuous with a thin plate-like front panel 510 that covers the front surface of the intermediate casing 50. This modeling can further improve the compactness. In addition, the front panel 501 can be structured to be detachable for maintenance by using a thin plate shape.

  The lower cover 40 is made of a PP resin material and is provided with height adjustment legs 406. In addition, a front cover 405 that is continuous with the front panel 510 is attached to the front part of the lower cover 40 so that the upper part is rounded. The maintenance cover 407 can be attached to and detached from the front cover 405. It is attached. Further, as shown in FIGS. 10D and 10E, assembly openings 525 are formed on the left and right side surfaces of the intermediate casing 50 to improve workability during assembly. The assembly opening 525 is attached with a cover in use.

Next, the opening / closing lid 70 provided with the operation panel 200, which is one of the features of this embodiment, will be further described with reference to FIGS. FIG. 12 is a part development view of the opening / closing lid. FIGS. 13A and 13B are explanatory diagrams of the operation of the opening / closing lid, in which FIG. 13A is a plan view of the opened state, and FIG. 13B is a side view of the opened state. FIG. 14 is an operation transition diagram of the opening / closing lid. FIG. 15 is a comparative study of opening / closing lids.
First, a component configuration of the opening / closing lid 70 will be described with reference to FIG. 12 showing a component configuration of the opening / closing lid 70. In this embodiment, the opening / closing lid 70 formed of a resin material includes a front opening / closing lid 710 and a rear opening / closing lid 720. The rear opening / closing lid 720 includes a rear upper cover 721 that covers an upper portion and a rear lower cover 722 that covers a lower portion. By combining the rear upper cover 721 and the rear lower cover 722, both members are attached with screws or the like so as to form a thin heat insulating space therein.

  On the other hand, the front opening / closing lid 710 includes a front upper cover 711 covering the upper part, a front lower cover 712 covering the lower part, an operation sheet 713 attached to the front upper cover 710, a handle part 731 and an operation board 114. Consists of The front upper cover 711 and the front lower cover 712 are combined to form an operation board storage portion therein and attached with screws or the like. The front lower cover 712 has a substrate attachment portion formed on the inner surface thereof, and an operation substrate 714 is attached to the substrate attachment portion.

  The front upper cover 711 is formed with an opening 715 at a position where the operation board 714 is exposed, and the operation sheet 713 is attached to the opening 715. The front upper cover 711 is formed with a hand recess 716 that is deeper toward the opening 715 between the opening 715 and the first connecting part 750. The handle portion 730 includes the handle recess 716 and the handle portion 731 attached to the front portion of the handle recess 716.

When the front opening / closing lid 710 and the rear opening / closing lid 720 are closed, the upper surface of the opening / closing lid 70 is flat, and in the opened state, the first connecting portion 750 rises upward and is folded in two. Then, the clothing input port 60 is opened.
In this embodiment, in order to obtain the opening / closing structure, one end of the rear opening / closing lid 720 and the front opening / closing lid 710 is rotatably attached to the first connecting portion 750. In this embodiment, the first connecting portion 750 includes a cylindrical rotary shaft member 751, a first rotary shaft support portion 752 provided at a central position of one end of the front opening / closing lid 710, and the rear opening / closing lid. 720 includes a pair of second rotating shaft support portions 753 formed at positions on both sides of one end of 720. The first and second rotating shaft support portions have a continuous cylindrical appearance in a combined state, and a rotating shaft storage portion 754 for storing the rotating shaft member 751 is formed therein. Therefore, by storing the rotary shaft member 751 in the rotary shaft storage portion 754, the front opening / closing lid 710 and the rear opening / closing lid 720 are rotatably connected. In this embodiment, the rotary shaft storage portion 754 is formed so that the outer periphery protrudes below the opening / closing lid 70 at a position lower than the upper surface of the opening / closing lid 70. Thus, when the opening / closing lid 70 is closed, the ends of the front opening / closing lid 710 and the rear opening / closing lid 720 are close to each other so that a gap is not conspicuous. The lid 710 and the rear opening / closing lid 720 are folded so as to be nearly upright.

  On the other hand, at both ends of the rear end portion Q2 of the rear opening / closing lid 720, bearing portions 762 attached to rotary shaft portions 761 (see FIG. 13) provided at both rear end portions of the clothing insertion port 60 are provided. The rotating shaft portion 761 and the bearing portion 762 constitute the second connecting portion 760. On the other hand, a rotation roller 770 is attached to both sides of the front end portion (free end) Q1 of the front opening / closing lid 710, and the rotation roller 770 is held by support rails 601 formed on both sides of the clothing input port 60.

This structure is further illustrated in FIG. FIGS. 13A and 13B are explanatory views of the attachment structure of the opening / closing lid, wherein FIG. 13A is a plan view showing a partial cross section of the support rail portion, and FIG. 13B is a conceptual diagram of the structure of the support rail.
In this embodiment, as shown in FIG. 13, when the opening / closing lid 70 is opened, the front opening / closing lid 710 and the rear opening / closing lid 720 in the upright posture are stored behind the clothing input port 60. . In this embodiment, a rectangular opening / closing lid 710 is employed as viewed from above. For this reason, the clothing input port 60 also has a rectangular shape. For this reason, the support rails 601 formed on both sides of the clothing input port 60 are parallel, and the rotating roller 770 positioned at the front end of the support rail 601 in a closed state is moved along the support rail 601 as the opening / closing lid 70 is opened. It can be moved backward.

(A) As shown in the figure, in this embodiment, the support rails 601 are formed so as to form grooves on both wall surfaces of the clothing input port 60 formed one step lower. Therefore, the pair of rotating rollers 770 is held by the pair of support rails 601 and has a structure that does not come off. This is because when the front end portion (free end) Q1 provided with the rotating roller 770 is lifted off the support rail 601, the lifted opening / closing lid 70 is released from a high position and collides with the clothing insertion port 60. Impact increases. In this embodiment, since the operation board 714 is provided on the opening / closing lid 70, in order to prevent damage due to this impact, a robust structure must be taken, and conversely, a robust structure is achieved. The operability and handling become worse.
Therefore, in this embodiment, the front end (free end) Q1 is structured so as not to be detached from the support rail 601, thereby improving operability and handling without taking unnecessary measures. .

  Further, as shown in FIG. 5B, in this embodiment, the front end portion P of the support rail 601 is curved. That is, the support rail 601 is formed to be curved so that the front end portion Z is bowed downward, and the rear thereof is formed of a linear inclined surface that gently rises upward. Accordingly, when the opening / closing lid 70 is moved forward and the opening / closing lid 70 is closed from the state where the opening / closing lid 70 is opened as shown in FIG. 5B, the rotation roller 770 moved at the same angle until just before closing. Will move downward with a steep slope at the final stage.

Thereby, since it can be expected that the two-fold opening / closing lid 70 is closed without any gap, it is possible to reduce the vicinity of the first connecting portion 750 from being lifted in the closed state. Accordingly, it is possible to reduce rattling of the opening / closing lid 70 that occurs when the operation panel 900 is operated in the closed state.
On the other hand, in this embodiment, a lock mechanism for holding the open / close lid 70 open can be provided so that the operation panel 900 can be operated without rattling even when the open / close lid 70 is open. For example, in this embodiment, a wedge member 607 that fits with the rotating roller 770 with the opening / closing lid 70 opened is provided behind the support rail 601. The wedge member 607 has an inclined surface formed downward. When the opening / closing lid 70 is pushed by the operation of the operation panel 900 or the like, the rotating roller 770 is moved to the lower sliding surface of the support rail 601 by the inclined surface. Since it is pressed, the pressure accompanying the said operation etc. can be received stably. The locking mechanism is not limited to the wedge member 607 but may include a recess that fits into the rotating roller 770.

Further, in this embodiment, since the front end portion (free end) Q1 of the opening / closing lid 70 has a curved shape, the rotating roller 770 can be positioned below the extension line of the plane of the opening / closing lid 70. Thus, the opening / closing operation can be performed smoothly, and a wide bowl-shaped insertion port 603 is obtained when opened, and the operation panel 900 at the time of opening is moderately inclined while obtaining a wide bowl-shaped insertion port 603. Can be obtained. This will be further described with reference to FIGS.
FIG. 14 is a cross-sectional view showing a step of the opening operation, and FIG.

  First, in FIG. 14, (a) shows a state in which the opening / closing lid 70 is closed. From this state, the user can perform the releasing operation through the handle portion 730 in the vicinity of the first connecting portion 750. At this time, since the rotating roller 770 is positioned below an extension line Z1 of the plane of the opening / closing lid 70 on which the handle portion 730 is provided, a virtual connection between the rotating roller 770 and the second connecting portion 760 is made. Since the handle portion 730 can be positioned above the line Z2, the handle portion 730 can be lifted more easily than the handle portion 730 provided in the virtual line Z2. In particular, in this embodiment, the first connecting portion 750 is positioned below the extension line Z1 so as to be flat when the upper surface of the opening / closing lid 70 is closed. For this reason, when opening the opening / closing lid 70, a large force is required at the beginning of the opening operation of pulling up the first connecting portion 750 positioned below the extension line Z1. In this regard, in this embodiment, since the first connecting portion 750 can be positioned on or above the virtual line Z2, the opening operation can be easily performed. Furthermore, since the support rail 601 is initially steeply inclined, the handle portion 730 can be more easily lifted.

  (A) From the state of the figure, as shown in the figure (b), when the rotating roller 770 moves to the linear inclined surface of the support rail 601, the weight of the opening / closing lid 70 composed of two members is the same as that of the rotating roller 770. Since the second connecting portions 760 are dispersed and supported, the opening operation can be smoothly performed along the inclined surface of the gentle support rail 601 as shown in FIGS. Then, as shown in FIG. 4D, the unlocked posture described above can be taken.

As shown in FIG. 15 (a), according to this embodiment, when the opening / closing lid 70 is opened, the front end (free end) Q1 of the opening / closing lid 70 is curved. The front opening / closing lid 710 provided with the above can obtain the length L1 before and after the wide bowl-shaped insertion port 603 while obtaining a large inclination angle Θ1 that is favorable for operation.
On the other hand, the front end portion (free end) Q1 of the opening / closing lid 70 is not curved, the ones shown in FIGS. For example, when trying to obtain a large inclination angle Θ1 that is favorable for operation, the length L1 before and after the wide bowl-shaped inlet 603 is reduced (L2). On the other hand, when an attempt is made to obtain the length L1 before and after the wide bowl-shaped insertion port 603, the large inclination angle Θ1 favorable for operation becomes small (Θ2).

  As described above, in this embodiment, the user pulls the first connecting portion 750 upward through the handle portion 730 so that the weight of the opening / closing lid 70 is increased with the second connecting portion 760. Since it is distributed and supported by the rotating roller 770, the load on the user can be reduced. In addition, the clothing input port 60 is opened and closed by the curved support rail 601 and the opening / closing lid 70 with an operation panel provided with the rotating roller 770 at the curved front end (free end) Q1 corresponding thereto.

Will also lead to. However, in this embodiment, since the frequently used operation switch is arranged in the center of the opening / closing lid 70 (operation panel 900), the above problem can be reduced.

  In this embodiment, a main operation switch is arranged below the three areas. As a result, when the open / close lid 70 is closed, it can be operated on the front side of the upper surface of the housing, and when it is closed, it can be operated at a low position. In particular, in this embodiment, when the open / close lid 70 is opened, the operation panel 900 is disposed on the open / close lid surface. For this reason, providing the switch behind the operation panel 900 means that when the opening / closing lid 70 is opened, the switch is operated at a high position of the standing opening / closing lid 70, that is, the opening / closing lid 70 is pushed at a high position. For this reason, each time the operation is performed, the opening / closing lid 70 in the standing posture is distorted or squeezed, which impairs the operational feeling and handling.

  In this embodiment, in order to solve the above-described problem, a main operation switch is provided on the front side of the operation panel 900. A display unit related to the rear of the operation switch is provided, and a switch and a display with extremely low use frequency are arranged behind the operation switch.

This will be described more specifically. First, the main operation area 910 is provided with a start / pause button 911 (main operation button 911) for driving or pausing in the foreground, and a main display unit 912 that displays the remaining operation time, reservation time, and the like behind the button. (Display unit). In this embodiment, since the operation mode selected at the time of previous use is stored, if the same operation as the previous operation is performed, this start / pause button 911 can be operated.
The mode selection area 920 has a hot water removal button 921 for selecting use of the hot water removal pump, a washing button 922 for washing only in the washing mode, and a washing button for selecting a mode from washing to drying. 923 and a drying button 924 for selecting a drying-only mode are arranged side by side.

An associated display section is provided behind these selection buttons. Behind the hot water removal button 921 is disposed a hot water removal display section 925 that sequentially displays lower modes selectable by the number of times this selection button is pressed, and behind the three selection buttons 922, 923, and 924. Is provided with a mode selection display section 926 that sequentially displays lower-order modes that can be selected according to the number of times these selection buttons are pressed.
On the other hand, in the detailed setting area 940, on the front side, a drying time setting button 941 for setting a drying time, a dehydration time setting button 942 for setting a dehydration time, a rinse count setting button 943 for setting the number of rinses, Washing time setting buttons 944 for setting the washing time are provided in a horizontal line. Behind these setting buttons, there is provided a setting content confirmation display section 945 for sequentially displaying the time or the number of times according to the number of times the setting button is pressed (operated).

On the other hand, in this embodiment, a reservation button 927 and a mold block button 928 are provided at the end of the mode selection area 920. Since these two buttons are operation buttons that are not operated much in normal operation, they are operation buttons that do not cause any trouble even in the rear position.
On the other hand, at the end of the detailed setting area 940, there are provided various warning display lamps 946 that warn of a dry capacity over, a dry filter, a high temperature display, a locked state, and the like, and a detergent amount display lamp 947. Since these various warning display lamps and detergent amount display lamps are not operated, the operation at this position does not cause any trouble.

  As described above, in this embodiment, the operation buttons are concentratedly arranged in a horizontal line in front of the operation panel 900 in the depth direction, so that a good feeling of operation can be obtained regardless of whether the opening / closing lid 70 is opened or closed. be able to. Then, by providing a display unit related to the operation button in the center in the depth direction, it is possible to check the current operation status even in a large display unit. In particular, in this embodiment, the operation button is assigned a function capable of selecting one of a plurality of modes, the number of times, or the time depending on the number of times the button is pressed. A display portion that can be selected corresponding to the number of operations is arranged. For this reason, it is possible to concentrate the operation buttons on the front portion of the operation panel which is the position where the operability is the best in the depth direction.

Next, the operation method will be described with reference to FIG. 16 and FIG. First, in this embodiment, a microcomputer (not shown) receives operation signals from the power switch 950 and the operation panel 200 and executes various operation modes.
When the power is OFF, the microcomputer sets the open / close lid 70 to be openable / closable without operating an open / close lid lock mechanism (not shown). Therefore, the user can always open and close the opening / closing lid 70 and put the clothes into the washing tub 10.

When the power switch 950 is operated, the microcomputer turns on the power, and displays the previous use state stored in a memory (not shown) on the operation panel 900. In this state, if the start / pause button 911 is operated, the same operation as in the previous use is performed.
On the other hand, when it is desired to perform an operation different from the previous time, one of the washing button 922, the washing / drying button 923, and the drying button 924 can be selected. In this embodiment, when any of the three buttons is operated, the microcomputer sets “standard” in the mode selection display unit 926. When setting other than “standard”, by operating an arbitrary button from the mode selection display unit 926, the microcomputer lights up the operated button and sets the mode of the button.

  Furthermore, the time and the number of times in various modes in the detailed setting area 940 can be received. In addition, by operating the hot water removal button 921, the pump can be operated when it is easy to wash. In addition, operations of the reservation button 927 and the mold block button 928 can be received to perform these operations.

  Next, when the start / pause button 911 is operated, the microcomputer temporarily operates the rotary tank 80 to measure the amount of clothes, and displays the amount of detergent corresponding to the amount of clothes. A display lamp 947 is displayed to prompt the user to input the amount of detergent and close the open / close lid 70. When the start / pause button 911 is operated again, the microcomputer confirms that the open / close lid 70 is closed by a sensor (not shown), and if closed, operates the open / close lid lock mechanism. The open / close lid 700 is locked. Then, the set operation is started.
