Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a washing machine processing agent feeding device that can automatically feed a predetermined amount of a detergent or finishing agent used in a general household into the washing machine.

Conventional Structure and Problems Conventionally, in a processing agent feeding device for a washing machine, in order to automatically feed, for example, detergent as a processing agent into a washing tub in a predetermined process, a detergent container storing one load of detergent is used for washing. There is one that is installed inside the machine so that it can be injected into the washing tub at predetermined intervals. However, this type of washing machine is inconvenient because it is necessary to measure the detergent and put it into the detergent container each time you wash the clothes.

In addition, the detergent container can store several doses of detergent, and an on-off valve and a flow control valve are provided in the path leading the detergent from the detergent container to the washing tub, and the flow control valve is opened in conjunction with the water in the washing tub. There is one that automatically dispenses detergent by changing the degree of detergent and opening the on-off valve at a predetermined timing for a predetermined period of time. However, according to this type of detergent, commercially available detergent stock solutions have different concentrations, so even if the amount of detergent is controlled in accordance with the amount of water in the washing tub, it is not possible to match the concentration of the detergent stock solution. Also, changes in room temperature change the viscosity of the detergent, causing the amount to be added to increase or decrease. Therefore, the concentration of the washing liquid in the washing tub becomes excessive or insufficient, leading to problems such as wasted detergent and deterioration of cleaning performance.

In addition, the detergent container can store several doses of detergent, and it is equipped with multiple measuring dispensers that measure the detergent from the detergent container and pouring it into the washing tub. There are those that operate the dispenser, and those that control the amount of detergent dispensed by operating the operating lever and changing the operating stroke of the dispenser.

However, this type of device has the problem that the structure is complicated and expensive.

Purpose of the Invention The present invention solves these conventional problems, eliminates wastage of processing agents such as detergents and finishing agents, and provides a processing agent feeding device for washing machines that improves washing performance and ease of use. It is something.

Structure of the Invention In the processing agent charging device for a washing machine of the present invention, the inner stage of the washing tub is provided with means for detecting the viscosity of the processing agent, and the charging time is controlled in accordance with the level of the viscosity of the processing agent.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. Figure 1 shows the schematic configuration of a washing machine with dehydrating function.
2 is the main body, 2 is an outer tank supported in a vibration-proof hanging manner within the main body 1, 3 is a spin-drying/washing tank (hereinafter simply referred to as a washing tank) arranged in the outer tank 2 so as to rotate automatically, and 4 is the washing tank 3. The agitating blade 6 arranged at the inner bottom is a motor, which transmits rotational force to the agitating blade 4 or the washing tub 3 by switching operation of the clutch mechanism e. 7 is a belt for transmitting the rotational force of the motor 5 to the clutch mechanism 6, 8 is a drain port, and 9 is a discharge hose to the outside of the machine.

Reference numeral 1o denotes an air trap provided at the bottom of the outer tank 3, and the air trap 1o communicates via an air hose 12 with a water amount detection switch 11 provided at the top of the main body 1, which is a water amount detection means.

Reference numeral 13 denotes an in-machine water supply pipe, through which water is supplied from an external port (not shown) into the washing tub 3 via a water supply valve 14 serving as a water supply means.

In FIG. 2, reference numeral 16 denotes a processing agent storage container provided at the top of the main body 1, in which, for example, liquid detergent is stored. Storage container 1
At the bottom of 6, there is a metering pump 1 which is a processing agent injection means for forcibly injecting the processing agent into the washing tub 3 via the liquid supply pipe 16.
7 is a provision. Reference numeral 18 denotes a viscosity detection means for the detergent stock solution, which is a dosing time control means (the viscosity of the detergent is proportional to the temperature, so a temperature detection means can also be used instead).
If the detergent has a high viscosity, use a metering pump 1 more than if the detergent has a low viscosity.
7 is set to be energized for a long time. That is, the operating time of the metering pump 17 changes depending on the detergent viscosity ratio, and the concentration of the detergent liquid in the washing tub 3 becomes an appropriate concentration.

To explain the operation in the above configuration, laundry is put into the washing tub 3, the set water level of the water amount detection switch 11 is adjusted according to the amount of laundry, the detergent concentration changeover switch 18 is set, and the timer (Fig. (not shown) is set and the power is turned on, the water supply valve 14 opens and water is supplied into the washing tub 3. When the set water level is reached, the water amount detection switch 11 is activated to supply water.

Quantitative determination is performed in conjunction with the water level setting of the water amount detection switch 11.
The operation time of the pump 17 is set, and the metering pump 17 is operated during the period from water supply into the washing tub 3 to the start of rotation of the agitation 4.
is operated, and detergent is injected into the washing tub 3 from the storage container 16. At this time, if the detergent viscosity detection means 18 detects high viscosity, the metering pump 1
7 is the ratio of detergent viscosity, which increases the operating time, so that the concentration of the accumulated liquid in the washing tub 3 can be set to an appropriate concentration.

The dosing operation is completed with a single opening/closing operation of the metering pump 17, and the intended purpose can be achieved in a short time.Furthermore, since the opening operation does not have to be repeated, it is also excellent in durability. It becomes something.

In the above embodiments, the case where liquid detergent is added to the washing tub before the start of washing has been described, but the same applies to the case where processing agents such as bleach and antistatic agents are added during the final rinse.

In this embodiment, the case where the water level is set manually has been described, but the same applies to the case where the water amount is automatically set according to the amount of cloth.

Further, in this embodiment, the processing agent storage container and the metering pump are built into the main body of the washing machine, but the same applies if they are provided separately.

Furthermore, although this embodiment has been described with respect to a dehydrating and washing machine, the present invention can be similarly applied to a two-tub type washing machine.

Effects of the Invention As is clear from the above embodiments, the processing agent charging device for a washing machine of the present invention includes a water supply means for supplying water into the washing tub, and a processing agent charging means for charging the processing agent into the washing tub. , the treatment agent inputting means is equipped with a treatment agent viscosity detection means, and by controlling the input time corresponding to the level of the viscosity of the treatment agent, the concentration of the treatment agent in the washing tub can be made appropriate; It is possible to prevent performance deterioration due to wastage of processing agent or shortage of processing agent, and improve usability. Furthermore, the feeding operation can be completed in a short time by one operation of the processing agent feeding means, and moreover, compared to the one that is operated repeatedly,
It has excellent durability.
