Definitions

  • the present invention relates to a drum type washing machine having a drum rotated about a horizontal or inclined axis.
  • the drum type washing machine hereby may be one that is constructed to continuously perform the dual processes of washing to drying, like many commonly available drum type washing machines.
  • a drum type washing machine has an outer tub, simply referred to as "a tub” hereinafter, in which a cylindrical basket drum is mounted to rotate about a horizontal or inclined axis. With the laundry loaded inside, the drum is rotated in the tub containing water. The drum thus rotating makes the laundry tumble, whereby the stain or the like is removed from the laundry.
  • Well known conventional drum type washing machines have a substantially rectangular parallel-piped housing equipped with a front door that opens laterally to put clothes in. When the door is opened, a throw-in opening provided at an end of the drum becomes visible through an opening provided in the tub.
  • drum type washing machines with the above structure, many consumers are dissatisfied because of the difficulty in loading or unloading clothes.
  • the throw-in opening is located very low. With this design, the difficulty in loading or unloading clothes cannot be completely eliminated even by placing the washing machine on a dedicated platform.
  • some drum type washing machines have a drum with an inclined axis to make the throw-in opening directed obliquely upward. In other washing machines, the throw-in opening is designed larger.
  • Another problem is related to the following washing method often carried out by consumers: (1) put the laundry in a solution of bleach or the like stored in a bucket or the like, and (2) transfer the laundry with the solution of bleach, or only the laundry, to the washing tub of the washing machine.
  • the laundry With the conventional drum type washing machine, the laundry often drips the liquid onto the floor when only the laundry is transferred from the bucket to the washing tub. Furthermore, it is very difficult to transfer the liquid itself from the bucket to the washing tub.
  • One possible method for eliminating the above user-unfriendly drum type washing machine is to form the throw-in opening not in the front but in the top of the housing, as in the case of whirl type washing machines.
  • To form the throw-in opening in the top of the housing it is necessary to form openings also in the tub placed right under the throw-in opening and in the drum enclosed in the tub.
  • Such a structure causes various problems that do not occur in conventional whirl type washing machines or drum type washing machines. Examples of the problems are as follows:
  • the main object of the present invention is to improve the user-friendliness of drum type washing machines, which are conventionally said to be inferior to whirl type washing machines in respect of user-friendliness.
  • the present invention proposes a drum type washing machine in which a drum with a substantially cylindrical peripheral wall is mounted to rotate about a horizontal or inclined axis in a tub enclosed in a housing, which further includes:
  • the drum position determiner controls the drum to come to such a position that the drum opening substantially coincides with the tub opening.
  • the door-linking mechanism makes the drum door open with the opening motion of the tub door.
  • the drum door is forced into its opening direction by a force whose magnitude is determined so that the force makes the drum door barely follow the opening motion of the tub door.
  • "barely” means that the force must be determined moderately. If the force is too strong, the drum door jumps up and abruptly opens the tub door at the moment when the drum door is unlocked. This might make the tub door hit the hand of the user. If the force is too weak, the drum door moves so little that the user may not recognize that the drum door is open even after it is unlocked. Or the drum door is still half-closed after the user has opened the tub door.
  • the force actuates the drum door to push the tub door slightly up when the drum door is unlocked, and to open the drum door following the opening motion of the tub door when the user opens the tub door. Because of this construction, the user can open and close the doors safely and with great ease of handling.
  • the first washing machine may be constructed as follows: the drum is mounted to rotate about an axis extending in the lateral direction; the housing has a slope declining from the top to the front; the throw-in opening is formed to extend over the slope; the lid is a foldable structure composed of at least a front part and a rear part which are hinged to each other at a bent part of the top of the housing, where the bent part corresponds to the rear end of the slope; and the lid stands behind the throw-in opening in a folded position when it is opened.
  • the lid is thinly folded and does not project frontward when standing behind the throw-in opening. This design of the lid assuredly prevents the lid from obstructing the loading or unloading of the laundry.
  • the tub door is constructed to open backward, the lid of the above design will never obstruct the opening motion of the tub door. Further, the lid of the above design can easily be opened by a user who is not so tall.
  • the first washing machine may be preferably constructed as follows: the drum is mounted to rotate about an axis extending in the lateral direction; the housing has a slope declining from the top to the front; the throw-in opening is formed to extend over the slope; and an control panel with control keys is placed on the slope.
  • the lid for closing the throw-in opening, the control panel with the control keys and a detergent container which is drawable frontward are arranged so that the lid is located at the center, and the control panel and the detergent container are located on both sides of the lid, respectively, or on one side of the lid only.
  • This construction is based on the idea that one method for eliminating the user-unfriendliness of the drum type washing machine is to provide the throw-in opening not in the front but in the top of the housing, as in the case of conventional whirl type washing machines.
  • the throw-in opening is formed in the top of the housing, but it is also formed to cover a part of the slope that declines from the top to the front. This design allows users to load or unload the laundry in a comfortable position with no difficulty.
  • the formation of the slope can improve the user-friendliness without decreasing the laundry capacity, because the slope is formed using only a dead space existing at the comer of the housing between the top and front walls of the housing and the peripheral wall of the drum when the drum is mounted to rotate about an axis extending in the lateral direction.
  • control panel is placed on the slope of the housing and is directed obliquely upward.
  • This design allows users to almost directly face the control panel in a comfortable position with no difficulty. Therefore, for example, the user can easily read the explanations of the control keys on the panel, and can easily operate the keys.
  • LED light emitting diodes
  • LCD liquid crystal display
  • the user does not need open the lid to put the detergent into the detergent container and to operate the keys of the control panel.
  • the lid is constructed to open backward, the lid in the opened position does not hide the control panel and the detergent container.
  • the user can put the detergent into the detergent container and operate the keys of the control panel with the lid open.
  • the first washing machine further includes:
  • the two latching mechanisms hold the drum door and the tub door in the closed position so that they do not open during the washing operation.
  • the user should first open the lid to make the surface of the tub accessible and then operate the operation mechanism to open the tub door.
  • the unlatching mechanism actuates the drum-door-latching mechanism to release the drum door from the closed position.
  • the unlatching mechanism actuates the tub-door-latching mechanism to release the tub door from the closed position.
  • the tub-door-latching mechanism and the drum-door-latching mechanism so that the tub door and the drum door independently move from the opened positions to the closed and latched positions.
  • the two doors are not linked with each other, so that the user needs first to close the drum door, and then to close the tub door.
  • the drum door were designed to close together with the closing motion of the tub, there might arise such a trouble that, when the doors are closed, an end of the laundry hanging out of the drum opening gets caught by the drum door closed and is hidden between the drum and the tub without being noticed by the user.
  • the user needs to close the drum door before closing the tub door. Therefore, if the laundry gets caught by the drum door closed, the user hardly fails to see it.
  • the above construction prevents damaging the laundry or the washing machine itself due to the laundry being caught by the drum door.
  • the unlatching mechanism may be constructed with the following elements: a first moving part which projects into or withdraws from the inside of the drum together with the operation of the operation mechanism, and contacts the drum-door-latching mechanism to release the latch when it fully projects; and a second moving part which actuates the drum-door-latching mechanism together with the operation of the operation mechanism to release the latch.
  • the first and second moving parts work at different timings together with the operation of the operation mechanism. Therefore, the timings for the two latching mechanisms to release the latches can be determined as desired.
  • the drum-door-latching mechanism is designed to hold the drum door in the latched position when the tub door is in the latched position.
  • the drum rotates with the drum door touching the inner surface of the tub. This situation not only generates abnormal noise but also causes trouble or damage.
  • the first washing machine may preferably include a stopper which contacts the edge of the drum door when the drum attempts to rotate with the drum door opened.
  • the present invention further proposes a drum type washing machine wherein a drum with a substantially cylindrical peripheral wall is mounted to rotate about an axis extending in the lateral direction of a tub enclosed in a housing, which further includes:
  • the second washing machine when the user opens the tub door, the drum door opens together with the tub door. Therefore, the user does not need to do any particular operation to open the drum door, and the loading or unloading of the laundry can be done with fewer working steps.
  • the two door elements open frontward and backward, respectively, where the front-side door element is laid frontward and closes the spaces between the drum and the tub and between the tub and the housing. Thus, the laundry is prevented from falling into or getting caught in the space while being loaded or unloaded.
  • the drum-door-linking mechanism may be constructed so that a closing operation of the tub door makes the moving part move to bring the engaging mechanism into engagement so that the drum door is closed.
  • the present invention further proposes a drum type washing machine wherein a drum with a substantially cylindrical peripheral wall is mounted to rotate about an axis extending in the lateral direction in a tub enclosed in a housing, which further includes:
  • the drum door constructed as a double door having two door elements, if the front-side door element is very long, it obstructs the loading or unloading of the laundry because it overly protrudes when laid frontward.
  • the third washing machine which is referred to as "the third washing machine” hereinafter
  • the throw-in opening is formed in the front-side part of the top of the housing, and the length of the front-side door element in the front-back direction is smaller than that of the rear-side door element.
  • This construction reduces the projection of the front-side door element in the laid position. Therefore, the front-side door element does not obstruct the loading or unloading of the laundry.
  • the length of the front-side door element so that the front-side door element in the laid position does not project at all, or projects by only a small amount, from the front of the housing. This design prevents the laundry from being caught by the door projecting from the front of the housing, or prevents the user from touching the door.
  • the present invention also proposes a drum type washing machine wherein a drum with a substantially cylindrical peripheral wall is mounted to rotate about a horizontal or inclined axis in a tub enclosed in a housing, which further includes:
  • the drum door has a projection formed in one door element and a hole formed in another door element to be engaged with the projection, and can be kept in the closed position by engaging the projection with the hole.
  • one door element must come over the other door element at the overlapping parts of the two door elements.
  • the washing machine of the first embodiment has a housing 1 having a part that declines with a slight roundness from the top 1a to the front 1b (the part is referred to as "the slope 1c" hereinafter).
  • a large throw-in opening 3 (Fig. 5) is formed over the slope 1c and the horizontal part 1d across the bent part B (Fig. 4), and a lid 2 is provided to close the throw-in opening 3.
  • the lid 2 When viewed from the side, the lid 2 as a whole looks like a dogleg with its front-side section declining downward.
  • the lid 2 is composed of a first lid member 2a and a second lid member 2b, both of which are hinged by a central shaft 2d horizontally extending in the lateral direction.
  • the rear end of the second lid member 2b is connected to a rear shaft 2c horizontally extending in the lateral direction in the rear part of the top 1a.
  • the lid 2 extends over the horizontal part 1d and the slope 1c of the top 1a of the housing 1, including the bent part B, which corresponds to the boundary of the two parts.
  • the central shaft 2d, at which the lid 2 bends, is located in the proximity to and in the front of the bent part B. Because of this design, even when the lid 2 is folded as shown in Fig. 5, the entire thickness of the lid 2 is small, and the lid 2 stands behind the throw-in opening 3 without obscuring the throw-in opening 3.
  • the height of the lower end of the lid 2, or the height of the front end A of the throw-in opening 3 must be determined appropriately. If the front end A is too high, the loading or unloading of the laundry will be hard for those users who are not tall. If it is too low, the lid 2 will be hard to open or close. In general, the height of the washing machine is confined to a certain range due to the limit of installation space or other factors. Taking this into account, the height of the front end A should be preferably 70-90 % of the height of the washing machine.
  • a detergent container 5 that is drawable frontward is placed on the left side of the throw-in opening 3 on the slope 1c, and an control panel 6 extending in the front-back direction is placed on the right side.
  • the control panel 6 is provided with various keys and display devices: the keys are used for setting the washing course, reservation time, etc., and the display devices are used for showing the state of setting, the progress of washing, the remaining time until the reserved time or until the end of operation, etc. Since the control panel 6 is directed obliquely upward, users can almost diretly look at the control panel 6 by standing in front of the washing machine and looking down. Therefore, the display is easy to view, and the keys are easy to operate.
  • the detergent container 5 and the control panel 6 are placed on the right and left sides of the lid 2, respectively. This placement provides an easy operation because the lid 2 obscures neither the detergent container 5 nor the control panel 6 when opened. The same effect can be obtained also by placing the detergent container 5 and the control panel 6 together on either side of the lid 2.
  • the detergent container 5 is a box-shaped body with its top entirely open.
  • the inside of the detergent container 5 is divided into three: a powder detergent chamber 5a, a liquid detergent chamber 5b and a softener chamber 5c.
  • the detergent container 5 is placed on the slope 1c, as explained above. Therefore, even when the distance by which the detergent container 5 is drawn frontward is small, the detergent container 5 widely exposes its top, while being widely supported from below. Thus, users can put the detergent or fabric softener into the detergent container 5 without opening it a long way.
  • the water inlet 7 is for the connection of an external water supply hose
  • the auxiliary water inlet 8 is for the connection of a suction hose for taking water from a bathtub for reuse.
  • a bath water supply pump 10 is placed beneath the auxiliary water inlet 8
  • a quadruple water supply valve 9 is placed beneath the water inlet 7.
  • the quadruple water supply valve 9 is for the following four purposes: to supply water through the detergent container 5, to supply either the detergent or the softener contained in the container 5, to supply water for a balancing operation to be described later, and to supply water for cooling humid air that contains steam emitted from the laundry during the drying operation.
  • the water supply valve 9 or the bath water supply pump 10 supplies water to a casing 11 for holding the detergent container 5 inside.
  • the water flows into one or more of the powder detergent chamber 5a, the liquid detergent chamber 5b and the softener chamber 5c.
  • the drum with the substantially cylindrical peripheral wall is mounted to rotate about a horizontal axis extending in the lateral direction.
  • the drum is generally mounted to rotate about an axis extending either horizontally in the front-back direction or an axis up-inclined from back to front.
  • a tub 20 which is a substantially cylindrical hollow body with both ends substantially closed, is supported by a pair of springs 21 and a damper 22.
  • the springs 21 pull up the tub 20 from the right and left sides of the housing 1, and the damper 22, extending in the front-back direction, supports the tub 20 from below.
  • the tub 20 is allowed to oscillate to a certain extent.
  • the tub 20 encloses a drum 23 to contain the laundry.
  • the drum is a substantially cylindrical hollow body with both ends substantially closed, and is rotatable about a horizontal axis C extending in the lateral direction.
  • the drum 23 has a number of holes 23c for letting the water pass.
  • the horizontal axis C is defined by a first bearing 26, which holds the main shaft 24 fixed to the left side of the drum 23, and a second bearing 28, which holds the auxiliary shaft 25 fixed to the right side of the drum 23.
  • the first bearing 26 is held by a bearing case 27 fixed to the left side of the tub 20, and the second bearing 28 is held by another bearing case 29 fixed to the right side of the tub 20.
  • Oil seals 31 are inserted between the main shaft 24 and the bearing case 27 and also between the auxiliary shaft 25 and the bearing case 29 so that no water reaches the first and second bearings 26 and 28 when water is stored in the tub 20.
  • a motor 30, which is a DC brush-less motor of outer rotor type, has a stator 30a and a rotor 30b.
  • the stator 30a is fixed to the bearing case 27, and the rotor 30b is fixed to the end of the main shaft 24 penetrating the tub 20 to the left.
  • the motor 30 is thinly constructed in the direction of the horizontal axis C.
  • the motor 30 thus constructed directly drives the drum 23 via the main shaft 24.
  • a driving voltage is supplied from a controller (not shown) to the stator 30a, whereby the rotor 30b is rotated, and the drum 23 is driven by the main shaft 24 to rotate at the same speed as that of the rotor 30b.
  • a drain 20c which leads through a drainage valve 36 and a drainage hose (nor shown) to an external drainage ditch.
  • the drainage valve 36 is opened or closed by a torque motor 37.
  • the washing machine has an air circulation passage on the right side of the tub 20. During the drying operation, the air circulation passage is used for supplying hot air into the drum 23 and for re-heating the air from which the steam emitted from the laundry has been removed by condensation and liquefaction.
  • the washing machine of this embodiment supports the drum 23 at both ends. Therefore, the vibration almost never occurs during a centrifugal extraction process even if the laundry is unevenly distributed.
  • the washing machine of this embodiment employs two types of balancing structures.
  • One is a fluid balancer 32 attached to the circumference of the left side of the drum 23, the same side as the motor 30.
  • the fluid balancer 32 is a hollow circular body containing a liquid, in which the motion of the liquid is moderately restrained. When attached to the drum 23, the balancer 32 works to suppress the vibration of the drum 23, like a balancing ring used in conventional whirl type washing machines.
  • the other is plural water tanks 33 radially attached to the circumference of the right side of the drum 23, opposite to the fluid balancer 32 across the drum 23.
  • Each water tank 33 is a pocket-shaped body opened to the inside.
  • the water tanks 33 are a part of a balance-adjusting mechanism of variable weight type, which further includes a nozzle 34 for injecting water into the water tanks 33, a water supply channel (not shown) for supplying the nozzle 34 with water from the water supply valve 9, etc.
  • the basics of the balance-adjusting mechanism are as follows. During the rotation of the drum 23, water is ejected from the nozzle 34 into one of the water tanks 33 when the objective water tank 33 is near the nozzle 34.
  • the water is held in the water tank 33 by centrifugal force, and becomes like a weight adding an eccentric load to the drum 23. Therefore, by injecting adequate amount of water into the water tank 33 that is opposite to the eccentric load due to the uneven distribution of the laundry across the central axis, the entire amount of eccentricity of the drum 23 can be reduced.
  • the balance adjusting methods and mechanisms proposed in the Japanese Patent Application No. 2001-161855 by the applicant can be used for performing the above-described operation.
  • the throw-in opening 3 is formed over the horizontal part 1d and the slope 1c of the lid 2, as described above, and a tub opening 20b for the loading or unloading of the laundry is formed from the upper part to the front part of the peripheral wall of the tub 20 at such a position that it coincides with the throw-in opening 3.
  • the tub opening 20b can be closed by a tub door 20a.
  • a drum opening 23b for the loading or unloading of the laundry is formed in the peripheral wall of the drum 23, with a drum door 23a for closing the drum opening 23b.
  • the laundry is loaded into or unloaded out of the drum 23 through the tub opening 20b and the drum opening 23b.
  • the drum 23, however, may rotate in the tub 20.
  • a drum-position-fixing unit 35 is placed under the stator 30a in order to hold the drum 23 in such a position that the drum opening 23b coincides with the tub opening 20b in radial direction.
  • a locking pin projecting from the unit 35 engages with a locking hole formed on the rotor 30b, whereby the position of the drum 23 is determined.
  • Figs. 10 to 13 the structures for opening and closing the tub door 20a and the drum door 23b for the loading or unloading of the laundry are described. These structures feature the washing machine of this embodiment.
  • the drum 23 is enclosed in the tub 20 placed under the throw-in opening 3 closed by the lid 2.
  • the tub opening 20b and the drum opening 23b are formed so that their orientations are inclined frontward from the upright direction.
  • the tub opening 20b and the drum opening 23b are closed by the tub door 20a and the drum door 23a, respectively. Therefore, to load the laundry into the drum 23, it is necessary to open the two doors, i.e. the tub door 23a and the drum door 20a. If both doors should be opened independently, users need to take the following troublesome three steps to load the laundry: to open the lid 2, to open the tub door 20a and to open the drum door 23a. Therefore, the washing machine of this embodiment is constructed so that the tub door 20a and the drum door 23a are opened by a single and simple operation.
  • the drum door 23a is composed of a front-side door 40 and a rear-side door 50.
  • the front-side door 40 is rotatable about a front shaft 41 extending along the lateral direction
  • the rear-side door 50 is rotatable about a rear shaft 51.
  • the front-side door 40 and the rear-side door 50 are laid overlapping each other at their end edges (Fig. 10).
  • the two doors open like a double door. With this double door structure, when the drum door 23a is opened, the front-side door 40 is laid forward and closes the space between the tub 20 and the drum 23.
  • the laundry while being loaded into the drum 23, the laundry is prevented from falling into or getting caught in the space between the tub 20 and the drum 23.
  • the front-side door 40 would obstruct the loading of the laundry if it projected too much when opened. Therefore, the front-side door 40 is designed to be shorte in the front-back direction than the rear-side door 50 so that it protrudes only a little.
  • the front-side door 40 is forced into the opening direction by a spring 42 wound on the front shaft 41.
  • a claw 43 directed upward is provided at the overlapping part of the front-side door 40.
  • the claw 43 is connected to a supporting plate 44 that functions like a spring. When a force is exerted from the outside of the drum 23 on the supporting plate 44, the claw 43 goes down into the inside of the drum 23, and when the force is removed, the claw 43 returns to the original position.
  • the rear-side door 50 is forced into the opening direction by a spring 52 wound on the rear shaft 51.
  • An engagement hole 53 to be engaged with the claw 43 is formed at the overlapping part.
  • the front-side door 40 and the rear-side door 50 are connected by a linking element 55, over which a cover 56 is placed.

  • the water in the tub 20 is renewed, and a rinsing operation is performed in a similar manner.
  • an intermediate or final extracting operation is performed. This time, the speed of the motor 30 is raised to, for example, about 1000 r.p.m. There, the drum 23 also rotates at that speed, whereby water is centrifugally extracted from the laundry.
  • the drum 23, the tub 20 and the housing 1 are prevented from excessive vibration because of the function of the fluid balancer 32.
  • the balancing mechanism also works there, if necessary. After the extracting operation, hot air is introduced into the drum 23 to dry the laundry. After the drying operation, the drum 23 is stopped, and the user unloads the laundry out of the drum 23.

Then, the operation lever 112 rotates about the shaft 113, and the rod 116 descends together with the rotation of the operation lever 112. As described above, the rod 116 is located so that it contacts the supporting plate 318 of the front-side door 312 of the drum door 310 when it fully projects. Therefore, in the position as shown in Fig. 16B, the supporting plate 318 is pushed down by the rod 116, whereby the front-side door 312 is rotated downward about the front shaft 311.
  • the claws 317 come off the engagement holes 319, removing the force pulling the rear-side door 314 downward, and the rear-side door 314 rotates in the opening direction due to the force of the spring.
  • the front-side door 312 also attempts to open after the rear-side door 314.

  • users usually open the tub door 110 a little later than operating the operation lever 112. Therefore, in practice, even if the drum door 310 and the tub door 110 are unlatched almost at the same time, the rear-side door 314 of the drum door 310 is opened together with the opening motion of the tub door 110.
  • the lower surface of the lower member 110b of the tub door 110 has a recess 110d for receiving the rear-side door 314.
  • the end edge of the rear-side door 314 enters the recess 110d, as shown in Fig. 18.
  • the end edge of the rear-side door 314 enters the recess 110d. If the drum 23 is driven with the rear-side door 314 in the above state, the end edge of the rear-side door 314 collides with the step of the recess 110d, and the motor 30 becomes overloaded. Thus, the abnormality can be detected based on the loading state of the motor 30.
  • the user closes the rear-side door 314 of the drum door 310 by rotating frontward the rear-side door 314 that is then standing with a slight inclination backward.
  • the front-side door 312 rotates ahead of the rear-side door 314 and reaches the closing position of the drum opening 300, and then the rear-side door 314 comes over the front-side door 312.
