Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an illuminating device having a function of a reflection type sensor and performing a blinking operation in response to a reflected wave of an optical signal from an object such as an operator's hand.

[0002]

2. Description of the Related Art Conventionally, the illumination of this type of illumination device is often performed with a wet hand, a dirty hand, or an object during cooking, and it is necessary to prevent dangers such as hygiene and electric shock. Therefore, in recent years, a device provided with a non-contact type operation switch function capable of blinking the light source without directly touching the operation portion has been developed.

A conventional lighting device with a blinking function using a non-contact type switch will be described below. First, FIG. 8 and FIG.
The configuration of the lighting device will be described with reference to FIG.

As shown in FIG. 8, the lighting device 1 is fixed to the lower surface of the hanging door 2 fixed to at least one wall surface,
It serves as a light source for illuminating the periphery of the cooking work surface of the top plate 4 attached to the cabinet 3. Further, a sink 5, a stove 6 and the like are incorporated on the top plate 4. As shown in FIGS. 9 and 10, in the main body of the lighting device 1, a fluorescent lamp 7 serving as a light source, a lighting circuit 8 for the fluorescent lamp 7 including a ballast, a lighting tube, and the like,
A so-called reflection, in which an oscillator 9 for pulse-transmitting a signal wave such as infrared light or an ultrasonic wave at a constant level period and a receiver 10 for receiving a reflected wave of the signal wave reflected by a shield are integrally housed in a case. A detection unit 11 of the mold sensor and a sensor control unit 12 for controlling the on / off of the power supply of the lighting circuit 8 by receiving a detection signal from the receiver 10 in the detection unit 11;
The detection unit 11 is fixed in close contact with the front end of the front cover 13 made of a translucent material of milky white acrylic of the lighting device main body 1 from the back side, and the close contact portion with the front cover 13 is the detection unit 11
However, the sensor detection window 14 is formed by perforating the rectangular plate so that the transmitted or received signal wave can be transmitted, and by fitting the transparent acrylic plate to the rectangular perforation so as to completely cover the perforated part. It was formed.

[0005]

However, in the above-mentioned structure, the detection window 14 is fixed to the end of the lighting device 1 as shown in FIG. 8, so that the detection window 14 may be detected depending on the installation plan in the kitchen device. There is a case where a sink 5 or a stove 6 is arranged on the side opposite to the fixed part 11 and a cooking work area with a high frequency is generally set around the sink 5 or the stove 6. It is very troublesome because the user has to leave the cooking work place and move to the vicinity of the detection unit 11 for operation.

Further, as shown in FIG. 11, when the hanging door 2 is of a type having a short height called a short length, when the hanging door 2 is arranged on the lower surface of the hanging door 2, the detecting portion 11 of the illuminating device 1 is 1.
Since it is located at a height of 8 m, it makes a worker with a height of about 1.5 m feel like stretching his back and operating.

On the contrary, as shown in FIG.
If a storage cabinet 15 for seasonings and the like is further arranged below the storage cabinet 15 and the lighting device 1 is installed on the lower surface of the storage cabinet 15, the detection unit 11 of the lighting device 1 is located at a height of about 1 m from the floor surface. Therefore, a person with a high height bends his / her waist and looks into the detection unit 11 so that the operability is very poor.

The present invention is intended to solve such a problem, and the switch operation is always appropriate regardless of the installation height of the lighting device, the area around the sink 5 and the stove 6 and the positional relationship in the kitchen device of the lighting device. It is an object of the present invention to provide a kitchen device including a lighting device capable of performing the above.

[0009]

In order to achieve the above object, the present invention provides a transmitter for transmitting a signal wave of a constant level,
From a detection unit provided with a reception unit that receives a reflected wave in which a signal wave transmitted from this transmission unit is reflected by an object, and a control unit that controls blinking of the light source of the lighting device by a signal from the detection unit A lighting device having a switch function by the reflection type sensor, wherein the reflection type sensor is movable in the lighting device.

[0010]

According to the present invention, with the above-described structure, the detecting section is provided with the transmitting section for transmitting the signal wave of the constant level and the receiving section for receiving the reflected wave of the signal wave transmitted from the transmitting section reflected by the object. Since it is movably arranged in the lighting device, it is not affected by the installation plan of the lighting device in the kitchen such as the installation height of the lighting device, the sink, and the positional relationship between the cooking work area around the stove and the lighting device. By making it possible to place the detection unit at an appropriate position that is always easy to operate, and smoothly performing the blinking operation of the lighting device during cooking work, the efficiency of cooking work is improved.
