Description

Detailed Description of the Invention (Technical Field) The present invention relates to a dehydrator that automatically controls the dehydration operation by detecting the presence or absence of dehydration liquid discharged from the object to be dehydrated, and particularly relates to a dehydration machine that automatically controls the dehydration operation while pouring water. The present invention relates to a dehydrator capable of performing a dehydrating and rinsing operation.

(Prior art) In general, this type of dehydrator, for example, the dehydrator section of a two-tank washing machine, detects the presence or absence of dehydrated liquid discharged from the object to be dehydrated, controls the dewatering operation, and automatically However, during the so-called dehydration rinsing operation, which aims to effectively remove the detergent contained in the dehydrated material by dewatering while pouring water, dehydration continues to flow from the dehydrated material. The automatic stop function does not work, and the user must manually stop the water filling and dewatering operations.

However, if the user stops the dehydration rinsing operation based on his or her intuition, the dehydration rinsing operation, which normally takes about 1 to 2 minutes to obtain a sufficient rinsing effect, may cause the operation time to be too long or too short, resulting in wasted water, electricity, etc. This resulted in the inconvenience that the rinsing effect was insufficient.

(Purpose) The present invention has been made in view of the above points, and provides a dehydration rinse end determination means for determining the end of dehydration rinse based on the elapsed time from the start of the dehydration rinse operation, and an output from the determination means. The device is equipped with a notification means for notifying the end of dehydration rinsing by a signal, and by notifying the user of the end of dehydration rinsing, it is possible to eliminate the conventional inconvenience caused by excessive or insufficient operating time.

(Example) Examples of the present invention shown in the drawings will be described in detail below.

FIG. 1 is a block diagram showing a control system of a dehydrator in an embodiment of the present invention. In Fig. 1, a microcomputer (1) and an electronic control circuit section (9) include a CPU (Central Processing Unit) 2, a fixed data memory ROM 3, a temporary memory RAM 4, a timer 5, and a 14 section (input/controller).
It is composed of an output section) 6. 7 is an operation switch for starting and stopping the dehydration operation, 8 is a dehydration detector that detects the presence or absence of dehydration liquid discharged from the object to be dehydrated and generates an electric signal, 9 is a dehydration motor, and 1O is a light emitting device. This is an indicator lamp (notification means) such as a diode. Then,
The CPU 2 determines based on the output signal from the dehydration detector 8 that the discharge of the dehydration liquid has become below a certain value, and controls the dehydration motor 9 based on this determination result to stop the dehydration operation. be.

Next, control during the dewatering and rinsing operation will be explained according to the flowchart of FIG. 2. First, the water faucet is opened to start pouring water into the dehydration tank, and then the operation switch 7 is turned on.The CPU 2 confirms that the operation switch 7 is ON, drives the dehydration motor 9, and lights up the indicator lamp 10.
By starting the timer 5, the dehydration and rinsing operation is started. Then, as time passes, the data T of the timer 5 becomes T! (Predetermined time suitable for dehydration and rinsing) When the CPU 2 is busy, the CPU 2 determines the completion of dehydration and rinsing, switches the indicator lamp 10 from a lighting state to a blinking state, and when the indicator lamp 10 blinks, the dehydration and rinsing ends. and notify the user. Then, when the user closes the water faucet to stop water injection and turns on the operation switch 7 again, the CPU
Step 2 confirms that the operation switch 7 is turned on for the second time, stops the dehydration motor 9, turns off the indicator lamp 10, and ends the dehydration and rinsing operation.

In addition, the indicator lamp 10 lights up even during automatic dehydration operation, and when T+
It switches to a blinking state as time passes, and also functions as an indicator lamp indicating that dehydration is in progress. in this case,
The indicator lamp 10 is automatically turned off at the same time as the dehydration motor 9 is stopped.

(Effects) As described above, according to the present invention, in a dehydrator that automatically controls the dehydration operation by detecting the presence or absence of the dehydration liquid discharged from the object to be dehydrated, the dehydration rinse that performs the dehydration operation while pouring water can be performed. When the execution is completed, the completion of the execution can be easily known by the notification by the notification means, and the inconvenience that conventionally occurred when relying on the user's intuition can be solved.

Incidentally, in the present invention, the notification means may be a buzzer or the like, as long as it can notify the user of the completion of the dehydration and rinsing.

Claims (1)

[Claims] 1. A dehydration detector is provided to detect the presence or absence of dehydration liquid discharged from the object to be dehydrated, and a control means is provided to automatically control the dehydration operation based on the output signal from the detector. In a dehydrator configured to perform a dehydration operation and a dehydration rinse operation in which dehydration is performed while pouring water, a dehydration rinse completion determination means determines the end of the dehydration rinse based on the elapsed time from the start of the dehydration rinse operation during the dehydration rinse operation. and a notification means for notifying the completion of dewatering and rinsing based on an output signal from the determination means.
