A motor for rotationally driving the drum,
The front part of the door and the outer box is inclined at a different angle from the front part of the drum.

  According to the above means, the protrusion of the lower part of the door and the lower part of the front part of the outer box according to the inclination of the front part of the drum is suppressed, and the applied weight of the opened door in the closing direction is reduced. As a result, the overall depth dimension can be reduced, the door does not close under its own weight, and the door can be stabilized in the open state, so the door does not interfere with the loading and unloading of the laundry. You can

Hereinafter, a first example (first embodiment) of the present invention will be described with reference to FIGS.
First, FIG. 1 shows a configuration of the entire drum-type washing machine, and a water tank 2 is disposed inside an outer box 1 that forms a rectangular box shape as a whole. The aquarium 2 has a drum shape, and is elastically supported on the bottom surface of the outer box 1 via a pair of left and right suspensions (only one is shown). The supporting form is such that the axial direction of the aquarium 2 is front and rear ( It is an inclined state that is forward and backward (upward to the left in the figure).

  A reinforcing plate 4 is attached to the closed rear end surface portion (right end surface portion in the figure) of the water tank 2, and bearings 5 and 6 are provided in the center of the reinforcing plate 4 and the rear end surface portion of the water tank 2.

A thicker drum support 12 made of metal, for example, is attached to the closed rear end surface of the drum 11, and a drum shaft 13 is attached to the center of the drum support 12 and the rear end surface of the drum 11. The drum shaft 13 is inserted from the water tank 2 into the bearings 5 and 6 of the bearing housing 7, so that the drum 11 is also arranged in an inclined state in which the axial direction is front and rear and rises forward, the same as the water tank 2. In addition, the water tank 2 is rotatably supported.
A rotor 10 of the motor 8 is attached to the rear end portion of the drum shaft 13 protruding from the bearing housing 7.

Further, the drum 11 is formed with dewatering holes 14 almost all over the barrel (only a part is shown), and baffles 15 are attached to several locations on the inner periphery of the barrel (this is also one). Only the part is shown).
The water tank 2 is provided with a heater 16 for heating the washing water on the outer bottom surface. In addition, a drain valve 18 is attached to the drain port 17, and a drain valve motor 19 for opening and closing the drain valve 18 is installed in the tank 2. It is attached to the outer bottom surface part. A drain hose 20 is connected to the drain valve 18.

  Further, a dehumidifier 21 is disposed on the rear side of the water tank 2, for example, on the left side. Is communicated with a casing 22 disposed on the upper side of the water tank 2. A fan 23 is provided in the casing 22, and a belt transmission mechanism 24 that rotates the fan 23 and a fan motor 25 are disposed outside the casing 22. In addition, a water supply valve 26 for supplying water into the water tank 2 is disposed at the upper corner of the outer box 1 outside the casing 22, and the supplied water is introduced into the water tank 2. The flexible water supply hose 27 to be inserted is connected.

  A duct 28 is connected to the casing 22, and a heater 29 is disposed in the duct 28. The heater 29 forms a hot air generating device 30 with the fan 23, and the front end of a duct 28 that blows out the hot air is connected to an air supply port 32 of the water tank cover 31.

  The water tank cover 31 is attached to the peripheral edge of the open front surface of the water tank 2 to form the front surface portion of the water tank 2, and has a ring shape having an opening 33 at the center. The water tank cover 31 has an upper portion 31b extending forward from the lower portion 31a, and the above-described air supply port 32 is formed in the extended upper portion 31b. Further, the water tank cover 31 is made of a heat-resistant material such as a metal such as an iron plate or a stainless steel plate, or a heat-resistant resin such as glass or filler blended polypropylene. The water tank 2 has an axial inclination angle substantially the same as that of the drum 11.

  On the other hand, the front surface portion 11 a of the drum 11 is constituted by a drum cover 34. The drum cover 34 is attached to the peripheral edge of the open front surface of the drum 11 and is also formed in a ring shape having an opening 35 at the center and is made of a heat-resistant material. The front surface portion of the drum cover 34, that is, the front surface portion 11 a of the drum 11 is inclined obliquely upward at an angle θ 1 with respect to the vertical surface according to the inclination of the drum 11.

  On the other hand, as described above, the outer box 1 has a rectangular box shape as a whole, but the front surface portion 1a is inclined obliquely upward at an angle θ2 with respect to the vertical plane. The angle θ2 is different from the inclination angle θ1 of the front surface portion 11a of the drum 11 and is set to be smaller than that. Specifically, the inclination angle θ1 of the front surface portion 11a of the drum 11 is 5 to 20 °, particularly 10 °, and the inclination angle θ2 of the front surface portion 1a of the outer box 1 is smaller by 2 ° or more than that. 3 to 15 °, particularly 5 °.

  In addition, a laundry entrance 36 is formed in the front surface portion 1 a of the outer box 1, and a door 37 is provided in the laundry entrance 36. The door 37 has a circular shape as shown in FIG. 2 according to the shape of the laundry doorway 36 (not shown), and its left end is pivotally attached to the outer box 1 by a hinge 38. The laundry doorway 36 is opened and closed by rotating left and right around the center 38. In the closed state, the door 37 is flush with the front surface portion 1a of the outer box 1. Therefore, the door 37 is also inclined obliquely upward at an angle θ2 with respect to the vertical surface. (See FIG. 1).

  The laundry doorway 36 is connected to the water tank cover 31 by a bellows 39. As shown in FIG. 2, a handle 40 for opening and closing and a hook 41 for holding a closed state are provided at the right end of the door 37. Further, the central portion of the door 37 is formed as a transparent portion by, for example, double glasses 42 and 43 (see FIG. 1).

In addition, in the front portion 1a of the outer box 1, a vertical surface 44 is formed over the left and right lateral widths in a portion below the door 37, and a kick-like recess 45 is also formed in the portion below the left and right sides. It is formed over the full width. A plurality of, for example, four legs 46 are provided on the outer lower surface portion of the outer box 1, while a work port 47 is formed on the rear surface portion of the outer box 1. A back plate 48 is detachably provided.
Further, as shown in FIG. 2, an operation panel 49 and a detergent charging case 50 are provided on the uppermost portion of the front surface portion 1 a of the outer box 1.

Next, the operation and effect of the above configuration will be described.
At the time of washing, the washing water (not shown) supplied through the water supply valve 26 is stored in the lower part of the drum 11 while the washing (not shown) to be thrown in from the laundry entrance / exit 36 is accommodated in the drum 11. After collecting the detergent from the detergent introduction case 50, the drum 11 is alternately rotated by the motor 8 at a low speed of, for example, 50 to 60 [rpm], for example, in both forward and reverse directions. Thereby, the laundry is stirred together with the washing water to perform washing. In this folding, the baffle 15 sequentially lifts the laundry and the washing water, and promotes the stirring of the washing and the washing water.

  At the time of dehydration, the drum 11 is rotated in one direction at a high speed of 800 to 2000 [rpm] by the motor 8 as described above. Thereby, the water contained in the laundry is discharged from the dewatering hole 14 by centrifugal force. The discharged water is discharged out of the machine through the drain port 17 through the drain valve 18 and the drain hose 20.

  Then, at the time of drying, the drum 11 is rotated alternately in, for example, both forward and reverse directions at a low speed of 50 to 60 [rpm] as in washing, for example, and simultaneously the fan 23 of the hot air supply device 30 is rotated and the heater 29 is turned on. Causes fever. As a result, the laundry is agitated, and the air in the drum 11 is passed through the dehumidifier 21, the casing 22, and the duct 28 in this order from the drain port 17 of the water tank 2, as indicated by arrows in FIG. The air is returned to the drum 11 from the air supply port 32 of 31 and circulated. Thus, in the circulation path, the air in the drum 11 is dehumidified in the dehumidifier 21, and the air in the drum 11 is heated by the heater 29 in the duct 28 to generate hot air. Therefore, hot air is supplied into the drum 11 from the air supply port 32 of the water tank cover 31, and the hot air is brought into contact with the laundry being stirred to dry the laundry.

  Now, in the drum type washing machine of this embodiment operated as described above, the door 37 that opens and closes the laundry doorway 36 does not have the same inclination angle θ2 as the inclination angle θ1 of the front portion 11a of the drum 11. , Different. Thereby, since the protrusion of the lower part of the door 37 according to the inclination of the front surface part 11a of the drum 11 is suppressed, the overall depth dimension can be reduced.

  In addition, since the inclination angle of the door 37 is made different from the inclination angle θ1 of the front surface portion 11a of the drum 11 in this way, the door 37 is less affected by its own weight in the closing direction. In other words, the door 37 can be stabilized in an open state, and the door 37 can be prevented from getting in and out of the laundry.

In addition, in the case of the present embodiment, the front portion 1a of the outer box 1 together with the door 37 is also inclined at an angle θ2 different from that of the front portion 11a of the drum 11, so that the lower portion of the front portion 1a of the outer case 1 is Since the protrusion up to the inclination of the front surface portion 11 of the drum 11 is suppressed, the overall depth dimension can be further reduced.
For these reasons, the inclination angle θ2 of the front face 1 of the outer box 1 is made smaller than the inclination angle θ1 of the front face 11a of the drum 11, thereby reducing the overall depth dimension and the door 37. It is possible to more reliably achieve stabilization of the open state.

  More specifically, the inclination angle θ1 of the front surface portion 11a of the drum 11 is 5 to 20 °, and the inclination angle of the front surface portion 1a of the outer box 1 is 3 to 15 °, which is 2 ° or more smaller than that. In this case, the visibility of the inside of the drum 11 and the ease of loading and unloading of the laundry can be actually obtained better, and the overall depth dimension can be reduced and the door 37 can be opened stably. Can be reliably achieved.

  Here, (a), (b), and (c) of FIG. 3 represent the viewing angle ψ of the user with respect to the inside of the drum 11 depending on the inclination angle θ1 of the front surface portion 11a of the drum 11. It can be seen that the viewing angle ψ of the user with respect to the inside of the drum 11 increases as the inclination angle θ1 of the front surface portion 11a increases to 0 °, 10 °, and 20 °.

  FIG. 4 shows how the inside of the drum 11 can be easily viewed, how easy it is to put in and out the laundry, and the rest of the laundry (the surface of the drum 11 after dewatering is attached depending on the inclination angle θ1 of the front surface portion 11a of the drum 11. Remaining clothing) and their overall results are represented by an evaluation based on the inventors' experiments. As is apparent from FIG. 4, the evaluation value can be increased as the inclination angle θ1 increases to 5 to 20 ° as compared with the case where the angle of the front surface portion 11a of the drum 11 is 0 °. Become. When the inclination angle θ1 is 20 °, the ease of taking out the laundry, the remainder of the laundry, and the evaluation value of the overall result are slightly reduced, but are still good evaluation values. Therefore, the inclination angle θ1 of the front surface portion 11a of the drum 11 is preferably 5 to 20 °.

  On the other hand, if the inclination angle θ2 of the front portion 1a of the outer box 1 is too large, the effect of reducing the overall depth dimension and stabilizing the open state of the door 37 cannot be obtained sufficiently. If it is too small, the visibility of the inside of the drum 11 and the ease of taking in and out of the laundry will be impaired. Therefore, the inclination angle θ2 of the front surface portion 1a of the outer box 1 is preferably 3 to 15 °, which is 2 ° or less smaller than the inclination angle θ1 of the front surface portion 11a of the drum 11.

  Further, a vertical surface 44 is formed in a portion below the door 37 in the front surface portion 11 a of the outer box 11. Thereby, the protrusion according to the inclination of the front part 11a of the drum 11 at the lower part of the front part 1a of the outer box 11 can be further suppressed, and the reduction of the overall depth dimension can be achieved more reliably. .

  In addition, in the case of the present embodiment, the water tank 2 is also provided in an upwardly inclined state similar to the drum 11, and the upper part 31 b is located in front of the lower part 31 a on the front side of the water tank 2, that is, on the laundry entrance 36 side. It has a water tank cover 31 that is long. As a result, the water tank cover 31 fits in a space between the front surface portion 1a of the outer box 1 and the front surface portion of the water tank 2 so that the upper portion is wider than the lower portion, and a mating member connected to the water tank cover 31, in this case, a bellow 39 The laundry entrance / exit 36 of the outer box 1 and the water tank 2 can be connected without any change.

In this case, an air supply port 32 for supplying hot air generated by the hot air generating device 30 into the drum 11 is formed in the upper portion 31 a of the water tank cover 31. Thereby, since the air supply port 32 can be formed there using the dimension of the upper part 31b extended longer than the lower part 31a of the water tank cover 31, it is not necessary to extend the whole depth dimension excessively, and the whole depth dimension. Can be more reliably achieved.
In this case, the water tank cover 31 is made of a heat-resistant material, so that deformation of the water tank cover 31 due to the heat of hot air passing through the air supply port 32 can be avoided.

In contrast to this, FIG. 5 shows a second embodiment of the present invention. The same parts as those in the first embodiment are denoted by the same reference numerals and the description thereof will be omitted, and only different parts will be described.
In this case, a bellows 51 in which an upper part 51b is extended from the lower part 51a to the drum 11 side is connected to the laundry entrance 36, and in this way, the front part 1a of the outer box 1 described above The bellows 51 fits in a space between the front part of the water tank 2 and the upper part wider than the lower part, and the mating member connected to the bellows 51, in this case, the water tank cover 52 remains flat, and the laundry of the outer box 1 The doorway 36 and the water tank 2 can be connected.

  Further, in this case, the air supply port 53 is further formed in the upper part 51 a of the bellows 51 by the mouth frame 54 made of a heat-resistant material. Even in this case, the dimension of the upper part 51 a extending longer than the lower part 51 a of the bellows 51 is provided. Since the air supply port 53 can be formed there, it is not necessary to extend the entire depth dimension, and the reduction of the entire depth dimension can be achieved more reliably.

The motor 8 may be an inner rotor type in which the rotor 10 is positioned inward of the stator 9, and the rotational power of the motor 8 is not directly applied to the drum 11 as described above, but a belt transmission mechanism. You may make it tell indirectly through etc.
In addition, the present invention is not limited to the embodiments described above and shown in the drawings, and can be implemented with appropriate modifications within a range not departing from the gist.
