Description

The present invention relates to a water supply device, and more particularly to a water supply device that detects an object to be detected by using a radio wave sensor.

Conventionally, a water peripheral device including a human body detection sensor for detecting a user and an operation unit for operating water discharge is known (see, for example, Patent Document 1).
In a water supply device such as the above-mentioned patent document, functional parts such as an operation unit, a water discharge unit, and a human body detection sensor are generally installed in the vicinity.
Infrared sensors are generally used as human body detection sensors.

In recent years, there has been a demand for improving the design of water-related devices by concealing the human body detection sensor in a position invisible to the user, and in order to meet this demand, a radio wave sensor is used as a human body detection sensor. Is being considered for use.

Japanese Unexamined Patent Publication No. 2011-067453 (particularly FIG. 5)

However, when a radio wave sensor is used as the human body detection sensor, the detection range is wider than that of the infrared sensor. Therefore, if the human body detection sensor is installed at a position like a conventional water supply device, the user operates the operation unit. There is a risk that the radio wave sensor will detect the movement of the hand.

Therefore, the present invention solves the problems of the prior art as described above, that is, the object of the present invention is that the user operates the operation unit in the water supply device having the radio wave sensor and the operation unit. This is to prevent the radio wave sensor from erroneously detecting the movement of the user's hand and the movement of the operation unit at that time.

The invention according to claim 1 comprises a water spout having a spout, an operation unit for operating a spout state of the spout, a water receiving portion for receiving a spout flow discharged from the spout, and a radio wave. In a water supply device including a radio wave sensor unit that emits radio waves and detects the user's operation by receiving the reflected wave of the radio wave, the radio wave sensor unit is arranged above the spout of the water discharge unit. A detection region is formed by radiating radio waves from above the spout of the spout to include the spout, and the operating portion is arranged in front of the radio sensor. The operation area including the operation unit and the range of movement of the user's hand operating the operation unit is arranged outside the detection area formed by the radio wave sensor unit in the horizontal direction, and is radiated from the radio wave sensor unit. It is a water-surrounding device characterized in that a radio wave damping member for dampening radio waves to be generated is arranged between the radio wave sensor unit and the operation unit.

According to this water supply device, the operation unit and the operation area including the range of movement of the user's hand operating the operation unit are arranged outside the detection area formed by the radio wave sensor unit, so that the operation unit can be operated. Since it is difficult for the radio wave sensor unit to detect the movement of the user's hand and the movement of the operation unit, the radio wave sensor unit detects the movement of the user's hand and the movement of the operation unit when the user operates the operation unit. It is possible to prevent erroneous detection.
Further, since the radio wave damping member that attenuates the radio wave radiated from the radio wave sensor unit is arranged between the radio wave sensor unit and the operation unit, the radio wave radiated from the radio wave sensor unit propagates toward the operation unit. By making it difficult, the detection area and the operation area are less likely to interfere with each other, so that the radio wave sensor unit erroneously detects the movement of the user's hand and the movement of the operation unit when the operation unit is operated by the user. It is possible to further suppress the storage.

It is characterized in that it is arranged on a virtual vertical line passing through the spout and is arranged above the spout of the spout, and the detection region is formed downward so as to include the spout of the spout. It is a water supply device.

According to this water supply device, in addition to the effect of the invention of claim 1, the radio wave sensor unit is arranged on a virtual vertical line passing through the water discharge port of the water discharge unit and above the water discharge port of the water discharge unit. Since the detection area is formed downward so as to include the spout, the detection area formed by the radio wave sensor unit can be formed in a direction other than the operation unit. Therefore, the detection area and the operation area can be formed. It becomes more difficult for the radio wave sensor unit to interfere with each other, and it is possible to further prevent the radio wave sensor unit from erroneously detecting the movement of the user's hand and the movement of the operation unit when the operation unit is operated by the user.
