Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an auxiliary agent injection device for a washing machine in which a liquid laundry auxiliary agent such as a liquid detergent, a rinse agent, and a finishing agent is put into a washing tub.
[0002]
[Prior art]
Conventionally, an auxiliary agent introduction device for introducing a laundry auxiliary agent such as a liquid detergent, a rinse agent, and a finishing agent into a washing and dewatering tank has been configured as shown in FIGS. Hereinafter, the configuration will be described.
[0003]
As shown in FIG. 6, the aid case 1 is housed in a water injection device 2 so that it can be pulled out, and a water injection port 3 for injecting tap water into the aid case 1 is provided in the water injection device 2. The tap water poured from the water filling port 3 overflows from the aid case 1 and is poured into the washing tub (not shown) from the water flow port 4 of the water pouring device 2.
[0004]
In the above configuration, when the auxiliary case 1 is pulled out, the laundry auxiliary agent 5 such as liquid detergent, rinse agent, finish, etc. is put in and stored in the water injection device 2, and tap water is injected from the water injection port 3, the injected tap water As shown in FIG. 7, water is poured in the form of thinning the washing aid 5 in the aid case 1, and the water is poured together with the washing aid 5 into the washing tub through the flow path 4 through the path a. When the water injection from the water injection port 3 is completed, the auxiliary liquid including the laundry auxiliary agent 5 remaining in the auxiliary agent case 1 is discharged from the path b by the siphon principle, and is injected into the washing tub through the water outlet 4.
[0005]
The siphon principle will be described. When the water is injected from the water inlet 3 and the water level rises to the position c, the auxiliary liquid including 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 of the auxiliary liquid in the auxiliary agent case 1 can be discharged in a chain. This principle is widely known as a liquid drainage device.
[0006]
[Problems to be solved by the invention]
In such a conventional configuration, as shown in FIG. 8, the water injection 7 from the water injection port 3 may overflow to the handle 8 side of the aid case 1 particularly when the water injection speed is faster than the discharge speed of the auxiliary liquid. In addition, there was a problem that the handle 8 was soiled with the aid liquid containing the laundry aid 5.
[0007]
Further, when the amount of water injected from the water injection port 3 is large and the cap 9 for discharging the auxiliary liquid is constituted by another siphon lid (not shown) according to the siphon principle, this siphon lid and the auxiliary agent case 1 When the fitting of the siphon is not good, the siphon lid comes off in the water injection, and the chain outflow of the siphon principle is excluded, resulting in the problem that the auxiliary liquid remains in the auxiliary agent case 1.
[0008]
In addition, when the amount of water injected from the water injection port 3 is large, air may be entrained when water is injected into the aid case 1, and this air may enter the path b, thereby excluding the siphonic principled outflow. In particular, there was a problem that the aid liquid remained in the aid case 1 .
[0009]
The present invention solves the above-described conventional problems, and even when the water injection speed is high, the auxiliary liquid containing the laundry auxiliary agent is prevented from overflowing outside the auxiliary agent case, and is prevented from being stained with the auxiliary liquid. The purpose is to allow the washing aid to be poured into the washing tub.
[0010]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention accommodates an auxiliary agent case having an auxiliary agent input part for supplying a laundry auxiliary agent such as a liquid detergent, a rinse agent, and a finishing agent in a water injection device so that the auxiliary case can be pulled out. Water is injected into the washing tub through the agent case, and a water injection port for injecting water into the auxiliary agent case is arranged in the water injection device. After the water injection from the water injection port is completed, the auxiliary liquid containing the laundry auxiliary agent in the auxiliary agent introduction part is In principle, a route for discharging is provided in the auxiliary agent input part, and a gap is provided between the front side of the auxiliary agent case on the drawer side and the auxiliary agent input part. The auxiliary liquid is discharged through the gap and onto the water outlet .
[0011]
As a result, even when the water injection speed is high, the auxiliary liquid containing the laundry auxiliary agent overflowed from the auxiliary agent input part by the water injected into the auxiliary agent case passes through the gap provided between the auxiliary agent input part. It is possible to prevent the overflow of the auxiliary liquid that is discharged to the water outlet and contaminates the handle on the outside of the auxiliary case, and the auxiliary liquid does not contaminate the outside of the auxiliary case while the washing auxiliary agent is contaminated. Water can be poured into the washing tub.
[0012]

[0023]
In the above configuration, the water injected from the water injection port 3 does not directly enter the aid case 10 by the water injection reflection surface 17 of the lid 16, and the water pressure from the water injection port 3 can be relieved. Water is not poured into the aid case 10 vigorously, and air can be prevented from entering during water injection. Moreover, the air entrained in the aid liquid can be separated by strong water injection.
[0024]
As a result, when the water injection from the water injection port 3 is completed, the auxiliary liquid including the laundry auxiliary agent 5 remaining in the auxiliary agent charging part 11 of the auxiliary agent case 1 is discharged from the path b by the siphon principle, and the auxiliary agent It is possible to prevent the auxiliary liquid containing the laundry auxiliary agent 5 from remaining in the auxiliary agent input part 11 of the case 1.
[0025]
(Example 4)
As shown in FIG. 5, the lid 18 is disposed in the aid case 10, and is provided with a U-shaped fitting joint 15 that fits into the gap 12, and at a position facing the fitting joint 15. A portion 19 is provided, and the handle portion 19 is configured to be detachable from the aid case 10. Other configurations are the same as those of the second embodiment.
[0026]
In the said structure, since the cover 18 is comprised so that it may fit in the clearance gap 12, it can be firmly attached to the adjuvant case 10 similarly to the said Example 2, and the water injection from the water inlet 3 is carried out. The lid 18 will not be detached or displaced due to water pressure or the like.
[0027]
When the lid 18 is removed for maintenance such as cleaning, the lid 18 can be easily removed by putting a finger on the handle portion 19 and pulling it, and maintenance such as cleaning can be performed.
