Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auxiliary agent injection device for a washing machine for supplying a liquid laundry auxiliary agent such as a liquid detergent, a rinsing agent and a finishing agent to a washing tub.

[0002]

2. Description of the Related Art Conventionally, an auxiliary agent feeding device for feeding a laundry auxiliary agent such as a liquid detergent, a rinsing agent, a finishing agent, etc. into a washing / dewatering tub has been constructed as shown in FIGS. Less than,
The configuration will be described.

[0003] As shown in FIG. 6, a subsidy agent case 1 is housed in a water injection device 2 so as to be freely drawn out.
A water inlet 3 for injecting tap water is provided in the aid case 1. Tap water injected from the water inlet 3 overflows from the auxiliary agent case 1 and is injected from the water outlet 4 of the water injector 2 into a washing tub (not shown).

In the above configuration, the auxiliary agent case 1 is pulled out, and a laundry auxiliary agent 5 such as a liquid detergent, a rinsing agent, a finishing agent, etc.
When the tap water is injected into the water injection device 2 and the tap water is injected from the water inlet 3, the injected tap water is poured in such a manner as to dilute the laundry aid 5 in the aid case 1 as shown in FIG. Then, the water is poured into the washing tub along with the washing aid 5 through the flowing water port 4 through the route a. When the water injection from the water inlet 3 is completed, the auxiliary liquid containing the laundry auxiliary agent 5 remaining in the auxiliary agent case 1 is discharged from the path b by the siphon principle,
Water is poured into the washing tub through the water outlet 4.

To explain the principle of the siphon, when water is injected from the water inlet 3 and the water level rises to the position c,
The auxiliary liquid containing the laundry auxiliary agent 5 starts to fall from the tubular water passage 6. At this time, the falling auxiliary liquid works to suck up the auxiliary liquid in the auxiliary agent case 1 and all the auxiliary liquid in the auxiliary agent case 1 can be discharged in a chain. This principle is widely and generally known as a liquid drainage device.

[0006]

In such a conventional structure, as shown in FIG. 8, the water injection from the water injection port 3 causes the auxiliary agent case to be used especially when the water injection speed is higher than the discharge speed of the auxiliary liquid. There was a problem that the handle 8 could overflow on the side of the handle 8 and the handle 8 was contaminated with the aid liquid containing the washing aid 5.

When the amount of water to be injected from the water inlet 3 is large and the cap 9 for discharging the aid liquid is constituted by a siphon lid (not shown) as a separate part by the siphon principle, the siphon lid and the aid Agent case 1
When the fitting of the siphon is loose, the siphon lid comes off during the pouring, so that the chain outflow based on the siphon principle is alienated, and as a result, the subsidy liquid remains in the subsidy agent case 1.

If the amount of water injected from the water injection port 3 is large, air may be entrained when water is injected into the auxiliary agent case 1, and this air may enter the path b to avoid the chain outflow of the siphon principle. There was a problem that the subsidizing solution remained in the subsitant case 1 as a result.

In addition, when the siphon lid is fitted and the siphon lid is fitted so as not to shift to the auxiliary agent case 1, it is difficult to remove the lid when performing maintenance such as cleaning. Had the problem that

The present invention solves the above-mentioned conventional problems, and prevents the auxiliary liquid containing the laundry auxiliary agent from overflowing to the outside of the auxiliary agent case even when the water injection speed is high, and prevents the auxiliary liquid from being stained with the auxiliary liquid. The purpose is to allow the washing aid to be poured into the washing tub while preventing it.

[0011]

According to the present invention, in order to achieve the above object, an auxiliary agent case having an auxiliary agent input section for inputting a laundry auxiliary agent such as a liquid detergent, a rinsing agent and a finishing agent is drawn into a water injection device. It can be stored as possible, water can be injected into the washing tub from the water outlet through the aid agent case, and a water injection port for injecting the aid agent case is provided in the water injection device. A gap is provided between them.

Thus, even when the water injection speed is high, the auxiliary liquid containing the washing aid overflowing from the auxiliary agent inlet due to the water injected into the auxiliary agent case is provided between the auxiliary agent inlet. It is discharged to the water outlet through the gap, and it can prevent overflow of the subsidy solution that stains the handle on the outside of the subsidy case.While preventing the outside of the subsidy case from being stained with the subsidy solution, washing The aid can be poured into the washing tub.
