Description

[Detailed description of the invention] 【Technical field】

The present invention relates to an automatic faucet device that detects an object such as a hand or tableware held out below a spout and supplies water from the spout.

[Background technology]

Conventional automatic faucet devices use sensors such as infrared sensors and ultrasonic sensors to detect objects such as hands, and when the object enters the detection range, turn on the motor valve and discharge water or water from the spout. Hot water was discharged, and when no object was detected within the detection range, the switch was turned off to stop the supply of water or hot water. In this way, the sensors conventionally used in automatic faucets only detect the presence or absence of objects within the detection range, and do not have a distance measurement function, so the control of the water spout also involves switching between spouting and stopping water. It was only. However, with automatic control that only opens and closes kitchen faucets, the water suddenly stops flowing when the water stops, which is inconvenient when you want to pour water into a measuring cup or pour a certain amount of water into a pot. There were many things.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned technical background, and its purpose is to enable not only the start and stop of water supply from the spout, but also the adjustment of the water supply amount. It is in.

[Disclosure of the invention]

In the automatic faucet device of the present invention, a pulp 4 for adjusting the amount of water spouted from a spout 2 is provided in a faucet 1, and an object 10 such as a hand held out below the spout 2 is present in the vicinity of the spout 2. A distance measuring sensor 3 is provided to detect the distance to the object 10, and the pulp 4 is opened and closed depending on the presence or absence of the object 10, and the amount of water spouted from the pulp 4 is adjusted depending on the distance from the spout 2 to the object 10. It is characterized by comprising a control section 5. When an object 10 such as a hand or tableware enters the detection range, the pulp 4 is turned on and water is discharged from the spout 2, and when it disappears from the detection range, the pulp 4
When the switch is turned off and the water supply is stopped, and the object 10 moves away from or approaches the water outlet 2, the distance measuring sensor 3 detects the distance to the object 10* and adjusts the distance according to the distance. It can increase or decrease the amount of water discharged. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The faucet 1 is fixed to a sink, wash basin, etc., and may be configured to swing or to discharge a mixture of hot water and hot water. A spout 2 is provided in the faucet 1, and an electrically controllable pulp 4 such as a motor pulp provided on the faucet 1 allows water to be spouted from the spout 2, stopped, or the amount of water supplied can be adjusted. It has become. A distance measuring sensor 3 is attached near the water spout 2. The phase measuring separation sensor 3 consists of a light emitter 6 using a light emitting diode (LED) or the like, and a light receiver 7 using a position measuring detector (PSD) or the like having a distance measurement function. Unit (CPU) 5 is AD'! It is connected to the light projector 6 and the light receiver 7 via the i-changer 8.9, and is also connected to the pulp 4. The light emitted from the projector 6 of the distance-measuring sensor 3 hits an object 10 such as a hand and is reflected, and when it enters the receiver 7, the distance to the object 10 is detected, and the distance is shown in the triangular graph in Figure 1. When it is within the range indicated by , the pulp 4 is opened and water is discharged from the spout 2 by a command from the control unit 5, and when it is outside this range, the pulp 4 is closed and the water supply is stopped. Further, when the object 10 is moved up and down within this range, the amount of opening and closing of the pulp 4 is adjusted by commands from the control unit 5, and the amount of water supplied from the water spout 2 changes. That is, when the object 10 is raised, the amount of water supplied gradually decreases, and when the object 10 is lowered, the amount of water supplied gradually increases. Therefore, for example, when storing water in a container, when the water supply is nearing the end, if the container is gradually lifted up, the amount of water supplied decreases to 11+, and the correct amount of water can be stored in the container. Note that the amount of water supplied may be gradually reduced as the object 10 is lowered. Effects of the Invention 1 The present invention is structured as described above, so that when an object such as a hand or tableware enters the detection range, the distance-measuring sensor installed near the spout detects the object, and the pulp When the switch is turned on, water is discharged from the spout, and when there is no object within the detection range, the pulp switch is turned off and the water supply can be stopped, making it possible to operate the water supply without touching the faucet handle. Moreover, by moving an object such as a hand away from the water spout or bringing it closer, a distance-measuring sensor can detect the distance to the water spout and increase or decrease the amount of water spouted depending on the distance. The advantage is that you can adjust the amount of water supplied without touching the handle, allowing you to perform water and cooking tasks reasonably and efficiently.
