Description

[Detailed description of the invention] 3. Detailed description of the invention Industrial applications TECHNICAL FIELD The present invention relates to a water-filled detection device for type 2 washing machines.

BACKGROUND OF THE INVENTION Conventionally, a method of detecting when a tank is full of water has been to install a sensor in a drainage channel and detect overflow based on the sensor's output signal.

Problems to be Solved by the Invention When using such conventional methods to detect the fullness of water in the washing tub, it was not possible to distinguish whether water was overflowing due to full water during water supply or overflow during rinsing. Therefore, since it is not possible to detect when the water is full when water is being supplied, when water is being supplied to the washing machine, the washing machine must be monitored while the water is being supplied, which is inconvenient to use. Additionally, if the water supply was left unmonitored, water was often wasted due to forgetting to turn off the faucet.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a device that has a simple configuration and detects whether the washing tub is full of water when water is being supplied.

Means for Solving the Problems In order to solve the above problems, the present invention provides an overflow detection sensor that is installed near the overflow drain in the washing tub or in the overflow drain to detect overflow, and sets an agitation process in the washing machine. The washing machine is composed of a stirring process setting section for setting the washing machine, and a full-water detecting section for obtaining full-water information of the washing machine by inputting the respective output signals of the above-mentioned two.

Effect of the present invention With the above-described configuration, the case where overflow is detected by the overflow detection sensor and the agitation process signal is output from the agitation process setting section, the case where water overflow during water injection rinsing, and the case where the agitation stop signal is output are the case. The full water detection unit determines that the water is full in the water supply process.

Embodiment An embodiment of the full water detection device for a washing machine according to the present invention will be described below with reference to the drawings.

In the figure, 1 is a washing tub, 2 is a motor for generating a water flow in the washing tub, and the motor 2 is connected to an agitation process setting section 3 that sets the agitation process. Reference numeral 4 denotes an overflow drain port for draining water so that the water level in the washing tub 1 does not increase beyond a certain level, and overflow water is drained from the overflow drain port 4 through an overflow drain channel 6.

The overflow detection sensor 6 detects water passing through the overflow drainage channel S and outputs an overflow detection signal.The overflow detection sensor 7 receives the stirring process setting signal from the stirring process setting section 3 and the signal from the overflow detection sensor 6 to detect full water. A full-water detection section 8 is a notification section controlled by the full-water detection section 7.

In the above embodiments, flooding usually occurs during the entire washing process, either during pouring before washing or rinsing, or during pouring and rinsing.

When pouring water to the appropriate level before washing or rinsing,
When the water level reaches the overflow drain 4, the overflow drains into the overflow drain 5.
flows through. It is detected by the overflow detection sensor 6,
Overflow detection signal is output.

On the other hand, since the motor 2 is not driven, the stirring process setting section 3 outputs a stirring stop signal.

Therefore, these output signals are input, and the full water detection section 7 detects that the washing tub 1 is full of water when water is being supplied.

Furthermore, during water injection rinsing, the overflow detection sensor 6 detects overflow and outputs an overflow detection signal. On the other hand, since the motor 2 is being driven, an agitation process setting signal is input from the agitation process setting unit 3, and the full water detection unit 7 detects that the washing machine 1 is in the water injection rinsing process. Then, a notification signal is sent to the notification section 8 controlled by the full water detection section 7, and the notification section 8 issues a full water notification using a buzzer with a frequency of one cycle different from the end notification or when the switch is turned on.

In this way, water overflow is detected, and depending on the presence or absence of a motor control signal, it is detected whether the overflow is due to full water when water is being supplied to the washing tub or the overflow is due to water pouring and rinsing, and the notification unit 8 notifies the user.

In this embodiment, only one overflow detection sensor is shown, but a plurality of overflow detection sensors may be used, and the overflow detection sensor may be installed anywhere within the washing tub.

Effects of the Invention According to the present invention, it is possible to detect full water when water is being supplied to the washing tub with a completely simple configuration, so there is no need to monitor until the washing tub is filled with water, which improves usability. You can save water by preventing water from running out.
