Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a water supply device for a washing machine that is configured to notify the proper water injection flow rate of the washing machine by displaying or generating a sound.

Conventionally, the flow rate of water injected into a washing machine has been determined mostly by the user's intuition or by adjusting the opening/closing degree of a tap based on the level of water coming out of the water inlet. However, according to these methods, it is not possible to clearly know whether the water injection flow rate is appropriate or not.

Also, if the flow rate of water injected into the washing machine is too low, such as during ``rinsing mode'', the ``rinsing'' time will take longer or damage the laundry, and if it is too high, a lot of water will be discharged without being used for rinsing. To avoid wasting water, it is necessary to inject a certain amount of water, for example, in a domestic washing machine, the water flow rate should be about 10 to 15 per minute.

The present invention notifies an appropriate water injection flow rate by operating a notification means using a switch that operates in accordance with the rotation angle of a rocking plate inserted into the water injection flow.

Embodiments of the present invention will be described below with reference to the accompanying drawings. In the figure, reference numeral 1 denotes a cylindrical water inlet provided in the main body A of the washing machine, and one end of the hose 2 is connected to a water faucet serving as a water source, and the other end of the hose 2 is connected to the water inlet 1. 3 is an operation panel (not shown) of main body A, for example.
This is a water channel installed in the lower part of the interior of the pipe, and is formed into a cylindrical shape by molding plastic. Reference numeral 4 denotes a fluid rectifier that exerts a rectifying effect to correct disturbances in the flow of water injected into the water channel 3, and is made of a plastic net or the like and is disposed within the water channel 3.

Reference numeral 5 denotes a swing plate whose one end is inserted into the water injection flow and whose other end is extended outside the water channel 3. A shaft 5' provided approximately in the middle of this swing plate 5 is rotatably supported by a bearing 6. ing. Reference numeral 7 denotes a weight plate that prevents one end of the swing plate 5 from floating up in the water flow. 8 is a small magnet piece attached to the other end of the rocking plate 5, and a reed switch 9, which opens and closes the contact by the action of magnetic force, is attached above the water channel 3 via a mounting plate 10. . The reed switch 9 is a freely rotatable rocking plate 5
It is closed only when the magnet is at a predetermined angle (when the magnet pieces approach), and the point is that the rocking plate 5
A switch is provided that operates only when the angle is at a predetermined angle.

Reference numeral 11 denotes a washing tub, and at its inner bottom there is a stirring blade 1 that rotates by receiving the rotational force of a motor (not shown).
2 is placed. 13 is a bearing that pivotally supports the stirring blade 12; 14 is a drain port provided in communication with the bottom of the washing tub 11; the drain port is opened and closed by a drain valve 15; Reference numeral 16 denotes a water overflow port provided in the upper part of the side wall of the washing tub 11, which causes water to overflow when the stirring blade 12 is operated while water is being poured into the washing tub 11, so-called water injection rinsing.

Reference numeral 17 denotes a notification means, which is composed of an indicator lamp and is connected in series to the reed switch 9 and connected to the power supply side.

One end of the water channel 3 corresponds to the water inlet 1, and water injected from the water inlet 1 enters the water channel 3. Further, the other end side of the water channel 3 exists at a water supply position to the washing tub 11.

Next, the operation will be explained. For example, in the case of "water pouring rinsing", the appropriate amount of water pouring is 10 to 15 per minute in a domestic washing machine. Therefore, the area of the oscillating plate 5 in the flowing water and the weight plate 7 are adjusted so that the flow rate is 10 to 15 per minute at the position where the small magnet piece 8 at the upper end of the oscillating plate 5 is closest to the reed switch 9. Just select the weight appropriately.

That is, in this case, in the case of "filling and rinsing" operation, in order to pour water into the washing tub 11 at 10 to 15 times per minute, all you have to do is adjust the opening and closing of the water faucet while watching the indicator lamp, which is the notification means 17, until the indicator lamp lights up. good.
When the appropriate amount is reached, the small magnet piece 8 attached to the rocking plate 5 will be in the closest position to the reed switch 9, and the indicator lamp will light up. In addition, if the amount of water injected is increased by accidentally increasing the opening degree of the water faucet, the rocking plate 15 will rotate and pass the position close to the reed switch 9, the tilt will increase and the indicator lamp will not turn off. Lights out. Therefore, it is sufficient to adjust the opening degree of the water faucet to a small value so that the indicator lamp lights up again. As described above, the appropriate water injection amount can be easily adjusted regardless of whether the water injection amount is larger or smaller than a predetermined value.

In the embodiment, an example was shown in which a display lamp was used as the notification means, but a buzzer may be used instead of the display lamp. That is, when the small magnet piece operates the reed switch, the buzzer sounds, and since it is unpleasant and undesirable for this sound to continue for a long time, a separate switch is opened and the buzzer is turned on. All you have to do is turn off the power.

Further, in this embodiment, a cylindrical waterway has been described, but the waterway can also be shaped like a gutter, and even in this case, there are substantially inside and outside of the waterway where both ends of the rocking plate are located. It is something.

Furthermore, although this embodiment describes the case where water is poured into the washing tub, the same effect as in this embodiment can be achieved when water is poured into the spin-drying tank side, which has been frequently used in recent years. In short, the present invention has great effects when it comes to pouring water into the tank.

As described above, according to the present invention, it is possible to electrically notify the optimal amount of water when pouring water into the tub of a washing machine, thereby improving the usability of the washing machine and saving water. acts effectively, and for example, the rinsing effect can be improved. In addition, by providing a flow regulator, it is possible to prevent the water injection flow in the water channel from undulating and to stabilize the rotation angle of the rocking plate, making it easier to detect the flow rate and increasing its accuracy.
