Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drum type washing machine having a drum which rotates about a horizontal axis or an inclined axis. In general, a drum-type washing machine can often perform washing to drying continuously, but the drum-type washing machine mentioned here may not be capable of drying.

[0002]

2. Description of the Related Art Conventionally, a drum type washing machine has a structure in which a cylindrical basket-shaped drum is rotatably arranged in an outer tub around a horizontal axis, and water is stored in the outer tub. The laundry stored in the drum is beat-washed by rotating the drum with. In order to put laundry in and out of the drum of such a drum-type washing machine, it is necessary to open a side-opening type door provided on the front panel of the washing machine. It was necessary to take an unreasonable posture, curling up and bending. On the other hand, in recent years, a drum type washing machine having a configuration in which a front portion of a drum is arranged obliquely upward and inclined so that laundry can be taken in and out with a more comfortable posture is commercially available.

[0003]

In a washing machine in which the drum is inclined as described above, if the drum is rotated relatively slowly during the washing operation, the rinsing operation, and further during the drying operation, the laundry may be gravity-induced. Tend to lean down the slope, that is, toward the back of the drum. However, in the drum type washing machine having the conventional configuration, no particular consideration is given to such a deviation of the laundry, and the large amount of the deviation of the laundry cannot be sufficiently stirred, so that the washing is not easy to wash. Shortage and uneven washing may occur.

[0004] Further, there is a conventional drum type washing machine in which the water stored in the outer tub is heated to enhance the washing performance. For this reason, the outermost portion of the outer tub having a cylindrical peripheral surface is provided. And the heater is housed therein. However,
Since it is defined for safety that the distance between the heater and the floor is equal to or greater than a predetermined value, it is necessary to provide an outer tub at a higher position in the outer box by that much. There is a problem that the height of the height becomes high.

The present invention has been made to solve such a problem, and a first object thereof is to
It is an object of the present invention to provide a drum-type washing machine having a configuration in which a drum is arranged so as to be inclined upward and forward, which can prevent a decrease in washing and rinsing performance due to a bias of laundry.

A second object of the present invention is to arrange a heater for heating water stored in an outer tub, particularly in a washing machine having a configuration in which a drum is arranged so as to rise forward and incline. An object of the present invention is to provide a drum type washing machine capable of suppressing the height of the outer shape by devising the shape.

[0007]

Means for Solving the Problems and Effects A first invention made to solve the above problems is an outer tub, a bearing provided in the outer tub, and a shaft rotatably supported by the bearing. And a drum having a substantially cylindrical peripheral surface and one end of the shaft fixed to a rear end surface of the drum type washing machine, wherein the front end surface of the drum is higher than the rear end surface. The baffle, which is disposed at an upward inclination and protrudes inside the peripheral surface of the drum, has a greater amount of protrusion on the rear end face side than on the front end face side.

In one aspect of the first invention, the baffle is formed such that, when it is located at the bottom of the drum, the surface facing the shaft or the front-back line formed by the top is substantially horizontal. It can be configured.

According to the drum type washing machine of the first invention,
Since the drum is arranged so as to be inclined downward from the front end face side toward the rear end face side, when the drum is rotated around the axis at a relatively low speed for washing, rinsing, or drying, the drum becomes The laundry accommodated therein moves gradually along the slope and is shifted toward the rear end face. Since the baffle has a large protrusion on the rear side of the drum, even if a large amount of laundry is concentrated, the baffle can lift the laundry upward with the rotation of the drum, and the entire laundry can be properly moderated. Can be stirred. Thereby, easy washing, or lack of drying and unevenness is reduced, high washing performance,
Rinsing performance or drying performance can be ensured.

Further, in the drum type washing machine according to the first aspect of the present invention, since the baffle protrudes from the front end face of the drum with a small amount, the user can take in and out the laundry through the clothes input opening provided in the front end face of the drum. There is also an effect that the baffle does not get in the way when the operation is performed, and the taking in and out of the laundry becomes easy.

Further, as described above, since the protrusion amount of the baffle is small on the drum front end side where the amount of laundry is relatively small, the contact area between the laundry and the baffle is small in this portion. In addition, there is an additional effect that the cloth is not damaged by the laundry.

In the drum type washing machine according to the first aspect of the invention, the distance between the front edge of the surface facing the shaft of the baffle and the front edge of the drum is the rear edge of the surface facing the shaft of the baffle. It is preferable that the distance be larger than the separation distance between the section and the rear end face of the drum. According to this configuration, the laundry is less likely to be caught in the gap between the trailing edge of the surface of the baffle facing the axial side and the rear end surface of the drum, so that the laundry can be reliably stirred and It is easy to take out when taking out, and the cloth damage of the laundry can be reduced.

It is more preferable that an auxiliary baffle projecting forward from the rear end surface of the drum be provided in addition to the baffle provided inside the drum peripheral surface. According to this configuration, even when the amount of laundry stored in the drum is large and the laundry cannot be sufficiently stirred only by the baffle provided on the peripheral surface, the laundry is reliably stirred using the auxiliary baffle. By doing so, it is possible to eliminate unevenness in washing and washing, or unevenness in drying.

If the auxiliary baffle is provided at a position that does not coincide with the mounting position of the baffle in the circumferential direction of the drum, the stirring effect can be further enhanced.

According to a second aspect of the present invention, there is provided an outer case, an outer tub installed in the outer case for storing water, a bearing provided in the outer tub, In a drum-type washing machine including a shaft rotatably supported by a bearing and a drum having a substantially cylindrical peripheral surface and one end of the shaft fixed to a rear end surface thereof, the outer tub has a cylindrical shape. A bottom portion having a peripheral surface formed by swelling partly in a lateral direction, a gap between the peripheral surface of the outer tub and the peripheral surface of the drum, and a swelling portion of the outer tub; A heater for water heating is provided so that at least a part of the heater is engaged with the heater.

According to the drum type washing machine according to the second aspect of the invention, in the outer box, the portion bulging outward from the cylindrical body forming the peripheral surface of the outer tub is the same as or lower than the lowermost portion of the cylindrical body. Is also located above, so that the heater is also located at or above the bottom of the cylinder. Therefore, it is not necessary to arrange the outer tub particularly high in order to keep the space between the floor surface and the heater at a predetermined distance or more, and the height of the outer box of the washing machine can be suppressed. Further, in this configuration, since the bottom of the outer tank can be formed into, for example, a flat surface instead of a curved surface, the outer tank can be stably mounted in the outer box.

In the drum-type washing machine according to the second aspect of the present invention, the bulging portion of the outer tub stores more water, and the amount of water for achieving the same water level increases. Therefore, in order to suppress the consumption of wasted water, it is preferable that the outer tub bulges outward only on one side divided into two on a vertical plane including the center axis of the cylindrical body.

A third aspect of the present invention for solving the above-mentioned problems includes an outer box, an outer tank installed in the outer box for storing water, and a bearing provided in the outer tank. A shaft rotatably supported by the bearing, and a drum having a substantially cylindrical peripheral surface and one end of the shaft fixed to a rear end surface thereof, wherein the drum has a front end surface higher than a rear end surface. In a drum-type washing machine that is disposed at a forward-inclined inclination so as to be located at a position deviated from a vertical plane including a center axis of the drum, a gap between the drum and the outer tub,
Further, a heater for heating water is provided in a range below the water surface when the water stored in the outer tub is at a minimum water level for washing.

That is, in the drum type washing machine according to the third aspect of the present invention, the heater is housed in the recess formed at the bottom of the outer tub, which is in a vertical plane including the center axis of the drum, as in the conventional drum type washing machine. Instead, it is a position that is left or right away from that position, and is the same as or higher than the bottom of the outer tub, and the water stored in the outer tub is the minimum for washing. A heater is provided in a range below the water surface even at the water level. Therefore, it is not necessary to arrange the outer tub particularly high in order to keep the space between the floor surface and the heater at a predetermined distance or more, and the height of the outer box of the washing machine can be suppressed similarly to the second invention. .

A fourth aspect of the present invention for solving the above-mentioned problems includes an outer box, an outer tank installed in the outer box for storing water, and a bearing provided in the outer tank. A shaft rotatably supported by the bearing, and a drum having a substantially cylindrical peripheral surface and one end of the shaft fixed to a rear end surface thereof, wherein the drum has a front end surface higher than a rear end surface. In a drum type washing machine which is disposed so as to rise forward so as to be at a position, a gap is provided between a rear end surface of the drum and a rear portion of the outer tub facing the same, and is provided in the outer tub. When the stored water is at the lowest level for washing, a heater for heating water is provided in a range below the water surface.

In the drum type washing machine according to the fourth invention,
Instead of installing a heater in the gap between the peripheral surface of the drum and the outer tank, the heater is installed in the gap between the rear end surface of the drum and the rear part of the outer tank facing the drum. Therefore,
In order to avoid contact between the heater and the drum, it is not necessary to extend the peripheral surface of the outer tank by that much. Further, since the space between the heater and the floor surface can be easily secured without separating the bottom of the outer tub from the floor surface, the height of the outer box can be kept low as in the second and third inventions. Can be.

It is held so as to be able to swing freely by a spring (not shown) to be pulled. The front portion of the outer tub 3 has a circular opening facing the clothing inlet 1b of the outer box 1. The opening 3a and the clothing inlet 1b are connected by a seal member 5 made of an elastic material such as rubber. Have been.

Inside the outer tub 3, a drum 6 having a substantially cylindrical peripheral surface for containing laundry is supported by a main shaft 7. That is, the drum 6 has a cylindrical body 6a having a large number of water passage holes 6e, and a circular opening 6
c, a front plate 6b and a rear plate 6d. The trunk 6a and the front plate 6b, and the trunk 6a and the rear plate 6d are respectively provided with flanges protruding from the front edge and the rear edge. After being joined by tightening, it is screwed. Main shaft 7
Is firmly fixed to the rear of the rear plate 6d of the drum 6, and is rotatably supported by a bearing 9 of a bearing fixing member 8 mounted on the rear of the outer tub 3.

A rotor 10 b of a motor 10, which is an outer rotor type DC brushless motor, is attached to an end of the main shaft 7 protruding rearward of a rear surface 3 c of the outer tub 3. Is fixed. The rotor 10b including the permanent magnet is arranged so as to surround the outer peripheral side of the stator 10a including the winding, so that the motor 10 has a thin structure in the extending direction of the main shaft 7. When a drive current is supplied from a control circuit (not shown) to the stator 10a, the rotor 10b rotates, and the drum 6 is driven to rotate via the main shaft 7 at the same rotation speed as the rotor 10b.

As is apparent from FIG. 1, the outer tub 3 in which the drum 6 is mounted is such that the central axis C of the drum 6 (which coincides with the central axis of the main shaft 7) is inclined by a predetermined angle θ with respect to the horizontal line H. It is arranged with a front rising slope. Here, the inclination angle θ is set to, for example, about 5 to 30 °. The inclination of the front part 1a of the outer box 1 is formed in accordance with the inclination of the outer tub 3 and the drum 6, but it is not always necessary to make the same angle.

A water supply section 11 including a water supply valve, a bath water supply pump, and the like is provided in an upper space in the outer box 1, and the water supply section 11 is provided with a tap water supply to an external water tap. A hose 11a and a bath water supply hose (not shown) leading to a bath tub and the like are detachably connected. In front of the water supply unit 11, there is provided a detergent introduction unit 12 that houses the detergent container 12 a so that the detergent container 12 a can be pulled out.
The water supplied from 1 to the detergent charging section 12 is supplied to the detergent charging section 1.
The water is supplied into the outer tub 3 from a water injection port 13 provided in front of the outer tub 3 through a water injection pipe 12b connected to the bottom of the outer tub 3. At that time, for example, at the time of water supply in the washing step, the powder detergent or liquid detergent previously stored in the detergent container 12a flows out into the water and is supplied into the outer tank 3, and for example, at the time of water supply in the final rinsing step. The softening agent or the like previously stored in the detergent container 12a flows out into the water and is supplied into the outer tub 3.

When water is supplied from the water supply unit 11 into the outer tank 3 and stored in the outer tank 3, the water flows into the drum 6 through the water passage hole 6e. In addition, water spouted from the laundry in the drum 6 during dehydration scatters to the outer tub 3 through the water passage hole 6e. A drain port 14 is provided at the bottom rear of the outer tank 3, and the drain port 14 is connected to an inflow port of a drain valve 15. When the drain valve 15 is opened, water stored in the outer tank 3 is discharged. It is discharged out of the machine through the drain pipe 16.

On the inner peripheral side of the body 6a of the drum 6, three main baffles 2 are formed around the main shaft 7 while maintaining a rotation angle of 120 °.
0, the main baffle 20 is raised on the rear side of the drum 6 so that its top surface is substantially horizontal when positioned at the bottom in the drum 6 (that is, parallel to the horizontal line H). It is formed in a low shape on the front side. The front and rear edge surfaces of the main baffle 20 are each inclined, but the distances Lf and Lb between the corners of the top surface and the front and rear plates 6b and 6d of the drum 6 are shown in FIG. As shown in FIG. 1, the front side is wider than the rear side (that is, Lf> L).
b) has become. Further, an auxiliary baffle 21 that protrudes forward is provided inside the rear face plate 6d of the drum 6 at a rotational position (that is, an angular position of about 60 °) between the adjacent main baffles 20. The operation of the main baffle 20 and the auxiliary baffle 21 will be described later.

As shown in FIG. 2, in the present drum type washing machine, the outer peripheral surface of the outer tub 3 has a cylindrical shape as a whole.
The lower right portion bulges outward from a circle centered on the central axis C (the circle indicated by A in FIG. 2), and has a shape in which the bottom is just formed in a flat shape. A heater 30 which is a sheath heater for heating water is provided in the bulging portion 3d of the outer tub 3.

FIGS. 3A and 3B are detailed views showing the mounting structure of the heater, wherein FIG. 3A is a top view and FIG. 3B is a side view. About U
A heater holder 31 is fixed to a non-heat-generating portion 30 a at the base of the heater 30 having a U-shape, and a tip portion is held by a holder 32. The heater holder 31 is fixed to the rear surface 3 c of the outer tub 3 via a water-tight sealing member, and the heater 30 is arranged to be inclined substantially parallel to the bottom of the outer tub 3.

During the washing operation and the rinsing operation, water is stored in the outer tub 3 so that at least the entire heater 30 is immersed therein, and a heating current is supplied to the heater 30 from the outside. As a result, the stored water is warmed, and the effects of promoting the dissolution of the detergent, improving the stain removal, and the like can be obtained.

Conventionally, for the position of the heater 30, the minimum value of the distance from the floor surface 50 is determined in order to ensure safety. When the heater 30 is installed in the bulging portion 3d of the outer tub 3 as in the present drum-type washing machine, the heater 30 comes to a position higher than the bottom of the outer tub 3, so that the Unlike the case where the heater is provided in a part further depressed from the bottom, the heater 30 and the floor 5
It is not necessary to raise the entire outer tub 3 in order to secure a separation distance from zero. As a result, the overall height of the washing machine can be reduced, and the space above the washing machine can be neatly used for effective use. Further, since the lower side of the bulging portion 3d of the outer tub 3 becomes flat, the outer tub 3 can be stably fixed on the outer tub fixing plate 17.

Next, the operation of the main baffle 20 and the auxiliary baffle 21 during the washing operation and the rinsing operation in the drum type washing machine will be described.

Before starting the washing, the user opens the door 2 and puts the laundry into the drum 6. In this drum type washing machine,
Since the opening 6c of the drum 6 and the clothes inlet 1b face diagonally upward, the user can easily store the laundry in the drum 6 without taking an unreasonable posture. At this time, even if the user leans forward in the drum 6 to store the laundry, when the washing operation is started and the drum 6 is driven to rotate, the laundry in the drum 6 gradually moves along the slope. It tends to move rearward and concentrate on the rear part in the drum 6. That is, at the time of the washing operation and the rinsing operation (and also at the time of the drying operation), the number of the laundry is small at the front side of the drum 6 and a large amount of the laundry is shifted to the rear side.

In this drum type washing machine, since the height of the main baffle 20 from the inner surface of the body 6a is larger at the rear side, more laundry can be scraped upward at the rear side. It has become. That is, even when a large amount of laundry moves to the rear side of the drum 6 as described above, the laundry can be sufficiently stirred, and unevenness of washing, excessively unevenness, and drying unevenness can be eliminated. Can be. Further, the laundry that is biased so as to stick to the rear plate 6d of the drum 6 is not easily stirred by the main baffle 20, but is reliably stirred by the auxiliary baffle 21 protruding forward from the rear plate 6d. Therefore, the entire laundry contained in the drum 6 is sufficiently stirred, and unevenness in washing, excessively unevenness, and unevenness in drying can be eliminated.

Further, since the main baffle 20 is low on the front side in the drum 6, the main baffle 20 does not hinder when the laundry is taken in and out of the clothes inlet 1b. Further, since the distance Lf on the front side of the drum 6 is larger than the distance Lb on the rear side, it is difficult for the laundry to enter the gap on the rear side, and therefore, when the laundry is taken out, the laundry is caught in the gap. The trouble of taking out can be reduced.

As described above, the drum type washing machine of the first embodiment can provide the user with high performance and ease of use. In addition, as described above, the height of the washing machine can be reduced and the upper space can be widely used, and the washing machine can be installed in a place having a window at the top without hiding the window.

Next, an embodiment of a drum type washing machine according to the fourth invention (hereinafter referred to as "second embodiment") will be described with reference to FIGS. The same or corresponding parts as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted unless otherwise required.

In this drum type washing machine, the outer tub 3 has no bulging portion, and its peripheral surface has a substantially perfect cylindrical shape. What differs from the first embodiment is the shape of the heater 40 and its installation position. That is, the heater 40 for heating water has an arc shape as shown in FIG. 5, and stands along the rear surface 3c of the outer tub 3 with its root held at the bottom of the outer tub 3. Is established. Also in this case, the heater 4
The uppermost part of 0 is always lower than the lowest water level L set in the outer tub 3 (that is, the drum 6) during the washing operation or the rinsing operation.

According to the structure of the second embodiment, the outer tank 3
Since the heater 40 comes to a position higher than the bottom of the outer tank 3, unlike the conventional case where the heater is provided in a portion one step lower than the bottom of the outer tank 3, the distance between the heater 40 and the floor 50 is different. There is no need to raise the entire outer tub 3 to secure the distance. As a result, the overall height of the washing machine can be reduced, and the space above the washing machine can be neatly used for effective use. Further, in this configuration, it is not necessary to provide the bulging portion 3d in the outer tub 3 as in the first embodiment, and the amount of water stored in the outer tub 3 at the time of rinsing and rinsing can be reduced. Of course, a bulging portion may be provided to stably fix the outer tank 3 on the outer tank fixing plate 17.

The above embodiments are merely examples of the present invention, and it is apparent that changes and modifications can be made as appropriate within the scope of the present invention.
