Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detergent supply device for a washing machine that supplies detergent together with water supply.

[0002]

2. Description of the Related Art Conventionally, for example, in a washing machine having a reservation function for a laundry operation, a detergent is set in advance, and the detergent is washed away by the water supply at the start of the laundry operation and supplied into the washing tub. The one that has been made available is provided.

However, in this structure, the top cover of the washing machine is fitted with the receiving case, and the receiving case is further provided with the water injector and the detergent introducing case. It is adapted to be received by a receiving case, washed away by water poured out from a water injector, and supplied into the washing tub.

[0004]

However, the above-mentioned conventional ones have the problems that the number of parts used is large and the cost is high.

The present invention has been made in view of the above-mentioned circumstances, and therefore an object thereof is to supply a detergent for a washing machine, which uses a small number of parts, is low in cost, and is capable of reliably and reliably supplying a detergent. To provide the equipment.

[0006]

In order to achieve the above object, in the detergent supply device for a washing machine according to the present invention, a top cover of the washing machine is integrally formed with a receiving part, and the receiving part is provided on the receiving part. The water supply receiving chamber with the lower surface opened, the detergent storage chamber having the upper surface opened and a part of the lower surface having an opening, a slit communicating from the water supply receiving chamber to the detergent storage chamber, and the slit facing the slit. The water supply receiving chamber is provided with a case having a water supply inlet for introducing water from a water supply valve.

[0007]

According to the above means, the number of parts used can be reduced because the receiving portion is integrally formed on the top cover of the washing machine. Also, with this configuration, the detergent is stored in the detergent storage chamber of the case from the open portion of the upper surface thereof, and at the time of supply, the water introduced from the water supply valve to the water supply receiving chamber through the water supply inlet hits the wall surface where the slit exists. At the same time, it is supplied to the detergent accommodating chamber in a shower shape by passing through the slit by water pressure, and the detergent accommodating in the detergent accommodating chamber is jetted from the opening of the lower surface of the detergent accommodating chamber to flow on the receiving portion to be supplied. or,
At that time, the water introduced into the water supply receiving chamber also flows out from the open portion of the lower surface of the water supply receiving chamber and flows on the receiving portion, whereby the detergent is supplied in a better manner.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. First, FIG. 3 shows a top cover 2 mounted on the outer box 1 of the washing machine.
In the center, a laundry entrance / exit 3 is formed, and a lid 4 for opening / closing the entrance / exit 3 is pivotally installed.

Here, the top cover 2 is made of plastic, and the center of the rear edge of the laundry entrance / exit 3 is shown in FIG.
Further, the concave seat-shaped receiving portion 5 shown in FIG. 2 is integrally formed and provided. Then, a case 6 is mounted on the receiving portion 5, and the case 6 has a water supply receiving chamber 7 whose lower surface is open.
A detergent accommodating chamber 9 having an open upper surface and an opening 8 at a part of the lower surface; a horizontally elongated slit 10 communicating with the detergent accommodating chamber 9 from the water supply receiving chamber 7; A water supply inlet 12 for introducing water from a water supply valve 11 is formed in the water supply receiving chamber 7. In addition, a gentle curved surface 13 is formed from the peripheral side surface portion to the bottom surface portion of the detergent accommodating chamber 9. Further, the water supply valve 11 is provided in the rear portion of the top cover 2, and is connected to the water supply inlet 12 of the case 6 by a bellows hose 14.

In the case of the above-mentioned structure, the detergent is contained in the detergent accommodating chamber 9 of the case 6 through the open portion of the upper surface thereof, which is not shown. In this state, when the detergent is supplied, the water supply valve 1
Water introduced from 1 into the water supply receiving chamber 7 through the bellows hose 14 and the water supply inlet 12 passes through the slit 11 by hydraulic pressure and is supplied to the detergent accommodating chamber 9 in a shower shape while hitting the wall surface where the slit 10 exists. The detergent contained in the detergent accommodating chamber 9 is jetted from the opening 8 in the lower surface of the detergent accommodating chamber 9 and flows over the receiving portion 5 to be supplied. In addition, the water introduced into the water supply receiving chamber 7 at this time also flows out from the open portion of the lower surface of the water supply receiving chamber 7 and flows on the receiving portion 5, so that the flow of detergent can be improved. I have to.

However, in such a functioning device, the receiving portion 5 is provided integrally with the top cover 2 of the washing machine, and the number of parts used can be reduced by that much as compared with the conventional one. It can be done at low cost. In addition, since the cost of the detergent supply device can be reduced in this way, the reservation timer can be installed in the ordinary type washing machine by the difference.

Further, while exhibiting such an effect, the detergent can also be supplied in good condition and reliably in combination with the water supply as described above.

[0013]

As is clear from the above description, in the detergent supply device for a washing machine of the present invention, a receiving portion is integrally formed on the top cover of the washing machine, and the lower surface portion is open on the receiving portion. The water supply receiving chamber, the detergent containing chamber having an open upper surface and an opening in a part of the lower surface, a slit leading from the water receiving chamber to the detergent containing chamber, and the water receiving chamber toward the slit. A case with a water supply inlet for introducing water from the water supply valve is provided, whereby the number of parts used can be reduced, the cost can be reduced, and the detergent can be combined well with the water supply. It has an excellent effect that it can be surely supplied.
