Abstract

PURPOSE:To improve drying efficiency without mounting the inclining rotating mechanism for a rotary drum by a method wherein the rotary drum maintains a state to be inclined at a given angle in the case of the rotary drum being in an empty state, and when the rotary drum is in a state to be filled with water, a state approximately equal to a vertical state from a given inclination position is maintained. CONSTITUTION:A water drum 4 is rotatably supported around support rods 13a and 13b forming a support axle. Since, during drying, a water drum 5 is inclined at a first angle theta1, through drive of a plunger, a fixed piece 15 is engaged with a hook 16, and the water drum 4 and the rotary drum 5 are fixed at the first angle theta1. Through running of a motor 7, the rotary drum 5 is rotated to effect a desired drying process. Since, during washing, cleansing, and dehydration, water is fed to the rotary drum, the water drum 4 is rotated centering around the support axles, and balanced at a second angle theta2. Through drive of the plunger of a hook 18, a fixed piece 17 is engaged, the water drum 4 and the rotary drum 5 are fixed at the second angle theta2, the rotary drum 5 is rotated, and a washing process is carried out. Further, unhooking of hooks 16 and 18 is effected through drive of the plunger.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a washing machine, and more particularly to a washing machine that can perform washing, rinsing, spin-drying, and drying as a series of washing cycles.

[Prior Art] Conventionally, this type of washing machine was manufactured by, for example, the Japanese Patent Application Laid-open No. 6! -19
There was one shown in No. 6993.

This conventional example will be explained based on FIGS. 4 and 5.

In the figure, a washing machine (1) is provided with a laundry entrance/exit (IC) approximately at the center of the first side (1b) of an outer frame (1a), and on the other hand, at the bottom of this outer frame (1a), A base (3) is installed which is elastically supported by a buffer member (2) mainly made of a coil spring or the like. On the base (3), a pair of support frames (3a), (3a) formed in a bifurcated shape are opposed to each other with a constant interval between them. At the upper end of such support frames (3a), (3a), a hollow cylindrical water tank (4) housed in the outer frame (1a) is rotatable about a horizontal axis (4a). It is pivoted.

The water tank (4) has a lid (not shown) at the top of the opening corresponding to the entrance/exit (IC) of the outer frame (1a) that can be opened and closed.
It is attached to the J-noh, and inside it is a hollow cylindrical rotating tank with an opening at the top and located directly under the lid.
5) is accommodated.

That is, the rotating tub (5) is a washing tub that also serves as a dehydration tub, and is appropriately formed with holes (not shown) for this dehydration.

The rotating shaft (5a) of the rotating tank (5) is provided so as to coincide with the central axis of the water tank (4) in the state shown in FIG.

In addition, this rotating shaft (5a) has its upper part protruding inside the rotating tank (5), and is equipped with a pulsator (6) for stirring the water flow.
) is attached.

Next, this rotating shaft (5a) is rotated by water 1! It vertically passes through the lower part of the water tank (4) and is rotatably supported by a bearing (9) attached to the outside of the water tank (4). A motor (7) for transmitting driving force to the rotating shaft (5a) via the belt (8) is located near the bearing (9).
) is installed.

On the other hand, a motor (10
) is fixed to the support frame (3a), and a worm gear (11) driven by this motor (10) is provided perpendicularly to this horizontal axis (4a). A pinion gear (12) corresponding to this worm gear (11) is fixed to the horizontal shaft (4a).

Therefore, when the four-mugya (11) is driven, the horizontal shaft (4a) rotates accordingly.
The water tank (4) and the rotating tank (5) can be rotated around a).

Next, the operation and effect of the conventional washing machine will be explained in relation to the rotational operations of the water tank (4) and the rotation tank (5).

In FIG. 4, the initial state of the water tank (4) and the rotating tank (5),
That is, the rotation axis (5a) of the rotation tub (5) is perpendicular to the installation ILi of the washing machine. In this state, washing, rinsing, and spin-drying are performed according to a predetermined program.

When the spin-drying process is completed, the laundry moves to a drying process, and at this time, the motor (1o) is driven. In response to the drive of this motor (1o), the worm gear (11) rotates the pinion gear (12). At the same time, water #e4 is moved while being pivotally supported by the support frame (3a) until it reaches a position rotated by 90 degrees from the above state, that is, the state shown in FIG. 5. When the motor (10) is stopped, the worm gear (11) stops, and at this time, the worm gear (11) fixes the horizontal shaft (4a) immovably.

At this time, the motor (
7) in the same manner as described above, since the rotating shaft (5a) is horizontal, the rotating tank (5) will move along the horizontal shaft (5a).
Rotates around a).

Therefore, when the rotating tank (5) is rotating like this,
Laundry is dried without being unevenly distributed.

When the drying process is finished, the motor (10) is rotated in the opposite direction to the rotation direction, and the worm gear (11) rotates the pinion gear (12) in the opposite direction in order to prepare for the next washing, rinsing, and dehydrating processes. While doing so, it returns to the initial state. Accordingly, the rotating tub (5) returns from the horizontal position II to the vertical position around the rotating shaft (5a), and one washing cycle is completed.

[Problem to be solved by the invention]

In such conventional washing machines, a motor, a transmission section, etc. are required to rotate the rotating tub, which increases the size and cost of the washing machine.

Furthermore, in the conventional example described above, since the rotary tub is completely tilted to the side by 90 degrees, it is necessary to secure a space for tilting the tub, which poses a problem in reducing the size of the washing machine.

[1] The present invention has been made in order to solve the above-mentioned conventional problem, and it is possible to fix the rotary tank in an inclined state during the drying process using a simple and inexpensive mechanism without increasing the size. The object of the present invention is to provide a washing machine that can do the following.

[Means for Solving the Problems] The present invention, which was made in view of the above-mentioned aspect, includes a water tank including a rotating tank, and a water tank that tilts at a predetermined angle when empty and approaches vertically when filled with water. a support means rotatably supported, and a first support means that fixes the aquarium when the aquarium is empty and reaches a predetermined tilted position, and releases the fixation when filling the aquarium with water.
The apparatus is characterized in that it includes a fixing means and a second fixing means that fixes the aquarium at a water filling position of the aquarium and releases the fixation when water is discharged.

[Function] According to the above configuration, when the rotary tank is in an empty state for drying, it is possible to maintain a state tilted at a predetermined angle by the first fixing means.

When the washing machine is in a water-filled state, the second fixing means can maintain the state approaching the vertical state from the predetermined inclined position.

This eliminates the need for a tilting rotation mechanism for the rotating tank.
By obtaining an efficient drying effect through tilted drying, the rotating tub can be operated in a nearly vertical state during washing.

Therefore, drying efficiency can be improved without increasing the size of the washing machine.

[Example] Hereinafter, an example of the present invention will be described based on FIGS. 1 to 3.
