Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water surrounding device, and more particularly to a water surrounding device that detects a detected object using a radio wave sensor.

2. Description of the Related Art Conventionally, there is known a bathroom vanity that detects the approach of a user and automatically activates lighting and the like.
In such a vanity, when the ultrasonic sensor is used to detect the user, it is necessary to expose the detection portion to the outside, which is a factor that impairs the design of the vanity.

Therefore, in the vanity described in Patent Document 1 below, a microwave switch is installed on the vanity, and the microwave switch detects a user in the vicinity of the vanity and operates electrical equipment such as an illumination lamp. I am letting you.
In this way, when the microwave switch is used to detect the user, the detection part does not need to be exposed to the outside, so the microwave switch can be completely hidden in the vanity, and there is no design restriction. , It is possible to realize a vanity with a high design.

However, in recent years, in a water-surrounding device such as a bathroom vanity or a kitchen, a shower head and a shower hose are provided in the housing to improve the usability, and the shower head can be pulled out from the housing.
In such a water surrounding device equipped with a shower head that can be pulled out, if an attempt is made to detect the approach of a user using microwaves, the movement of the shower hose due to the action of pulling out the shower head may also be detected. On the contrary, the usability may be impaired.

  Therefore, the present invention solves the problems of the prior art as described above, that is, an object of the present invention is to provide a water surrounding device capable of preventing erroneous detection due to an operation of pulling out a shower head. That is.

According to a first aspect of the present invention, a shower head having a spout, a shower hose connected to the shower head, a housing that houses the shower hose, radiates a radio wave, and receives a reflected wave of the radio wave. In a water surrounding device including a radio wave sensor unit for detecting the operation of a detected body, and a bowl for receiving water spouted from the spout , the shower head is provided on a standing wall portion provided above the rear portion of the bowl. Attached, the detection area of the radio wave sensor section includes the shower head, a movable area of the shower hose in the housing is arranged outside the detection area of the radio wave sensor section, and the radio wave sensor section is When the movement of the shower head is detected, the detection by the radio wave sensor unit is invalidated .

According to the water circumference device according to claim 1 configured as described above, since the movable region of the shower hose in the housing is arranged outside the detection region of the radio wave sensor unit, the shower head can be pulled out. Since the radio wave sensor unit does not detect the accompanying pulling out of the shower hose from the housing, it is possible to prevent the radio wave sensor unit from erroneously detecting the movement of the shower hose when the shower head is pulled out.
Further, since the detection area of the radio wave sensor unit includes the shower head, the movement of the shower head can be detected.
Further, when the radio wave sensor detects the movement of the shower head, the detection by the radio wave sensor is invalidated. Therefore, when the movement of the shower head is detected, it is determined that the shower head will move, and the radio wave sensor detects the movement of the shower head. It is possible to execute a control for stopping the detection of the motion of the detection body.

The invention according to claim 2 is a water-surrounding device, wherein the radio wave sensor portion of the invention of claim 1 is arranged on the opposite side of the shower head from the movable region of the shower hose. is there.

According to the water circumference device according to claim 2 configured as described above, in addition to the effect achieved by the invention according to claim 1 , the radio wave sensor unit is opposite to the movable region of the shower hose with respect to the shower head. Since it is located on the side, the movable area of the shower hose when the shower head is pulled out is outside the detection area of the radio wave sensor, so the radio wave sensor detects the movement of the shower hose when the shower head is pulled out. It can be further suppressed.

According to a third aspect of the present invention, in addition to the configuration of the water surrounding device of the first aspect, a water surrounding device further comprising a radio wave attenuation member that adjusts the detection area.

According to the water circumference device according to claim 3 configured as described above, in addition to the effect achieved by the invention according to claim 1, by further including a radio wave attenuating member, the shower hose can move in the housing. Since the area can be excluded from the detection area of the radio wave sensor section, the radio wave sensor section detects the movement of the shower hose when the shower head is pulled out even when the radio wave sensor having a wide directivity is used. Can be suppressed.

  According to the present invention, it is possible to provide a water surrounding apparatus capable of preventing erroneous detection due to an operation of pulling out a shower head.

The receiving antenna 162 receives the reflected wave that is reflected by the object to be detected after returning from the transmitting antenna 161.

  The mixer circuit 164 receives a part of the transmitted wave and the received wave, and outputs a detection signal to the control unit 180 based on these inputs.

The control unit 180 has a determination unit 181 and a storage unit 182.
The state of the object to be detected is identified from the detection signal output from the mixer circuit 164, and the determination unit 181 compares the result with a threshold value previously designed in the storage unit 182 for determination.
Specifically, the determination unit 181 calls the predetermined threshold value stored in the storage unit 182, and compares the voltage value of the detection signal with the predetermined threshold value called from the storage unit 182.
When the voltage value of the detection signal is equal to or higher than the predetermined threshold value called from the storage unit 182, that is, when the radio wave sensor unit 160 detects the movement of the detected object, the control of the determination unit 181 controls the water discharge and the illumination. To do.

<2. Operation of equipment around water>
Next, with reference to FIG. 4 and FIG. 5, the operation of the water surrounding device according to the embodiment of the present invention will be described.
FIG. 4 is a schematic front view of the internal structure of the water handling device according to the embodiment of the present invention.
FIG. 5 is a side view of the water surrounding device according to the embodiment of the present invention.

As shown in FIG. 4, the shower hose 150 extends back and forth in the left-right direction inside the housing 130, and has a U-shape and is housed inside the housing 130.
As a result, the shower hose 150 moves in the movable region R when the shower head 110 is pulled out.
The radio wave sensor section 160 has a predetermined directivity pattern and forms a detection area S which is a detection range of the object to be detected. The detection area S is arranged so as not to include the movable area R of the shower hose 150. There is.

  Further, as shown in FIG. 5, when the radio wave sensor section 160 is arranged so that radio waves are emitted downward from above the water outlet 111, and the detection area S is arranged so as to include the shower head 110, This is more preferable because the user can detect the hand approaching the shower head 110 to pull out the shower head 110.
