Abstract

PURPOSE: To improve handleability in feeding detergent by allowing a control circuit to preferentially turn OFF setting of a detergent amount selecting means when a course selecting means sets a specific course and the execution of the set contents is finished. CONSTITUTION: The course selecting means 203 is formed of a switch to set a series of washing operation by the unit of a course and the detergent amount selecting means 202 is also formed of a switch to selectively set the detergent amount. The control circuit 205 is formed of a microcomputer to display the set contents, etc., by controlling a display means 101 formed of an LED and to control a motor 209 driving a detergent feeding device 21 according to the setting result of the detergent amount. When the partial course of 'only washing' is selected by the means 203, OFF is set without regard to the contents set by the means 202 at the time of finishing the course. Since a detergent amount selecting means of next time is turned into an OFF state, operation can be started without resetting the detergent quantity to improve handleability.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a control device for a detergent dispenser that automatically dispenses detergent.

BACKGROUND OF THE INVENTION In a conventional detergent dispensing device, the amount of detergent to be dispensed is set by a detergent amount selection means, regardless of a course selection means for setting a course for a series of sequential operations.

Problems to be Solved by the Invention However, in the conventional configuration, when a user selects a specific course, for example, "wash only" in a fully automatic washing course, the user cannot reuse the detergent in the tub. If the user intends to wash the laundry again, the detergent amount selection means must be set to "off", which does not add detergent, each time, which poses a problem in that it is inconvenient to use.

In view of the above problems, the present invention aims to improve the usability of adding detergent.

Means for Solving the Problems In order to achieve the above object, the present invention provides a detergent amount selection means that is capable of selecting a plurality of detergent amounts including "off" which does not add detergent, and a detergent amount selection means that can perform a series of sequential operations. A course selection means for setting contents, a control circuit for managing a series of sequential operations, and a detergent dispenser for controlling the amount of detergent dispensed by the control circuit, and the control circuit includes a course selection means for setting the contents. When a specific course is set and execution of the setting is completed, the detergent amount selection means is preferentially set to "off".

Function According to the above configuration, if a specific course, a course in which the detergent put into the tank is reused, the detergent amount selection means is set to the "off" state for the next time, so the amount of detergent is set. Operation can be started without any repairs, improving usability.

Embodiment The basic configuration of a control device for a detergent dispensing device in an embodiment of the present invention will be explained with reference to FIG. In Figure 1, 203
Reference numeral 202 is a course selection means, which is composed of a switch, and sets a series of washing operations on a course-by-course basis. Reference numeral 202 is a detergent amount selection means, which is also composed of a switch, and which selects and sets the amount of detergent. 206 is a control circuit composed of a microcomputer, which controls the display means 101 composed of LEDs to display setting contents, etc., and also controls the detergent dispenser 210.
The motor 209 that drives the detergent amount is controlled according to the detergent amount setting result. Now, if the partial course "Washing only" is selected by the course selection means 203, "Off" is set at the end of that course, regardless of the contents set immediately in the detergent amount selection means. . This "off" indicates a state in which detergent is not added.

A specific embodiment of the present invention will be described with reference to FIG. In Figure 2, 201 is a 50/6 that discriminates the frequency of commercial power supply.
It is a 0 determination means and is composed of a diode, a transistor, etc. Further, 202 is a detergent amount selection means, which is constituted by a switch, and allows setting of a necessary detergent amount. 203 is also constituted by a switch, for example,
This is a course selection means for setting only a washing course, a fully automatic course from washing to dehydration, or setting a predetermined course, such as a wool washing course or a speedy course. 204 is a water level determining means for detecting the water level in the washing tub. Each of the above means 201゜202.203.2
04 is connected to a control circuit 205 composed of a microcomputer or the like.

The detergent amount set by the detergent amount selection means 202 is displayed on the control circuit 205 that controls the series of sequential operations. For example, a detergent amount display means 206 made up of an LED and a course display means 2Q ending made up of, for example, an LEI that displays the course selection result set by the course selection means 203 are connected. Furthermore, by driving the water supply valve 208 which is controlled by the control circuit 206 and controls the water in the tank, the motor 209, and the motor 209,
A detergent dosing device 210 provided inside for supplying detergent into a water supply path, and presence/absence detection means 211 for detecting whether or not the detergent dosing device 210 is attached to the washing machine are connected to the control circuit 205. A simple switch is sufficient for the presence/absence detection means 211.

The operation of the embodiment having the above configuration will be explained below using FIGS. 3 and 4.

That is, when the power is turned on, the control circuit 205 starts sequential operations. Then, in step 301, initial settings are first made. For example, the laundry amount setting is set to standard at this time. Further, at this time, the driving time of the detergent injection motor 209 is set in advance to 6oHz. Now step 302
Then, the control circuit 205 determines whether the frequency is 50 Hz or 60 Hz based on the output of the tso/eo determining means 201 (step 302). As a result, if it is determined to be 60Hz, the setting of 60H2 is changed to 60Hz (step 3o3).

Furthermore, based on the output of the presence detecting means 211, in step 304, it is detected whether or not the detergent dispenser 210 is installed in the washing machine.As a result, if the detergent dispenser 210 is not attached, in step 305, the detergent dispenser 210 is installed in the washing machine. The set driving time ('rl) of the motor 209 is set to "0".

If it is installed, it is determined in step 306 whether the setting by the detergent amount setting means 202 is "off". If it is “off”, step 306
Set the set driving time f to ``O''. If a certain set amount is set, the speedy course is set by the course selection means 203 in step 307,
If it is determined that the entire detergent is to be applied for a short period of time, a fixed time (To') is set at T so that a corresponding constant (small amount) of detergent is added (step 308). If it is not the speedy course, it is further determined in step 309 whether the washing course for the specific clothing, that is, the wool course is set in the course selection means 203, and if it is the wool course, the setting is The driving time T is set to "0" (step 306). If it is not a wool course, it is immediately determined in step 310 whether the water supply process has ended, and if the water supply process has ended, that is, if a predetermined water level has been reached by the water level determination means 204. In step 311, it is immediately determined whether the necessary detergent injection has been completed, and if it has been completed, the process moves to the next step as shown in step 312. In addition, if the detergent addition has not been completed or if it is determined in step 310 that the water supply process has not been completed, the set driving time TM is set to the standard determined by 50/60 determined in step 302. A time (T1) is set (step 313).

Further, when the detergent amount selection means 202 sets strong instead of standard, the constant value (T2) corresponding to 60/60 is reset to TM (step 316).
).

As a result of the above, in step 318, the motor 209 for supplying detergent from the detergent injection device 210 to the water supply channel has already been activated.
A set driving time TM is set respectively. Therefore, the time T from the start of driving the motor 209 is compared, and in steps 317 and 318, if TM<T,
Stop motor drive. Further, in step 319, it is determined based on the output of the water level determining means 204 whether the set water level has already been reached, and if the set water level has been reached,
That is, if the PS is ON, the water supply valve is operated intermittently (step 32o); otherwise, the water supply valve is operated continuously (step 321). When water supply and detergent injection are completed, as shown in Fig. 4, 322
It is determined whether all the set processes have been completed, and if not, the sequential operation is executed for each next process.

In addition, if the course has been completed, it is determined whether the completed course is a "wash only" course (step 324).
If you are only doing laundry, set the amount of detergent to be added to ``Off.''
The next initial value will be the state in which no detergent is added (step 3).
26). If not, the settings are displayed as standard (step 326). Then, the process enters a state of waiting for input by the setting means (step 327) and waits for the next start.

Effects of the Invention As is clear from the above embodiments, according to the present invention, when only a specific course for detergent reuse is executed, the detergent amount setting for the next time is automatically set to 1 off. ,
There is no need to reset the amount of detergent to "off" next time, which improves usability.
