Description

  The present invention relates to a kitchen apparatus provided with illumination means.

  Conventionally, a kitchen apparatus including a counter having a stove and a sink, a human body detection sensor, and illumination means has been used. In this kitchen apparatus, when a human body is detected by a human body detection sensor, illumination is automatically performed by illumination means (see, for example, Patent Document 1).

  By the way, since breakfast, lunch, and dinner are cooked during the day, the surroundings of the kitchen device are sufficiently bright and can be cooked without being illuminated by the lighting means of the kitchen device.

  However, in the kitchen apparatus described in Patent Document 1, when the human body detection sensor detects a human body, it is illuminated with illumination means, so that it becomes brighter and more dazzling than necessary and power is wasted.

  Further, in the kitchen apparatus described in Patent Document 1, even when a person who gets up while sleeping at night puts a drink such as water in a cup and places it in the sink, the human body detection sensor detects the human body and illuminates it. However, there is a problem that the above-mentioned person is awakened by being brightly lit, and there is a possibility that he / she may not sleep even if he tries to go to sleep again.

JP 5-7514 A (paragraph [0012])

  The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to provide an illuminated kitchen apparatus that can eliminate inconveniences such as waste of power caused by illuminating more than necessary with illumination means. I will provide a.

  The illuminated kitchen apparatus of the present invention includes a cooking table 2 provided with a stove 4 and a sink 5, illumination means 6 capable of changing illuminance to illuminate the cooking table 2, and human body detection for detecting a human body located in the vicinity of the cooking table 2. The sensor 7, the illuminance sensor 8 that detects the brightness around the cooking table 2, and the illumination means 6 at a predetermined illuminance according to the brightness detected by the illuminance sensor 8 when the human body detection sensor 7 detects a human body. And a control unit that controls to illuminate.

  According to this structure, since it illuminates according to the brightness which the illumination intensity sensor 8 detects when the human body detection sensor 7 detects a human body, it becomes possible to eliminate the illumination means 6 illuminating more than necessary.

  In addition, the control unit can perform control to illuminate in three ways: a light-off mode, a normal lighting mode, and a low-light mode in which light is darker than normal lighting, and the brightness detected by the illuminance sensor 8. When the brightness is greater than or equal to the first threshold, the extinction mode is executed, and the brightness detected by the illuminance sensor 8 is greater than or equal to the second threshold that is less than the first threshold and smaller than the first threshold. In this case, it is preferable to execute the normal lighting mode, and execute the low light mode when the brightness detected by the illuminance sensor 8 is less than the second threshold.

  According to this configuration, when the brightness detected by the illuminance sensor 8 is greater than or equal to the first threshold, it is not necessary to illuminate with the illumination means, and the brightness detected by the illuminance sensor is less than the second threshold. In some cases, it is illuminated in low light mode, so it is not necessary to illuminate in lighting mode.

  In the present invention, it is possible to eliminate inconveniences such as waste of electric power caused by illuminating more than necessary with the illumination means and awakening of a person who woke up during sleep.

It is a perspective view of one embodiment of a lighting kitchen device of the present invention. It is a figure which shows the correlation of the change of the brightness with respect to the time change of a day, the relationship between a threshold value, and illumination mode.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  The illuminated kitchen device 1 according to the present invention is mainly composed of a cooking table 2 having a stove 4 and a sink 5. The cooking table 2 includes a cooking table cabinet 21 and a counter 3 installed on the upper surface of the cooking table cabinet 21.

  FIG. 1 shows an example of a face-to-face kitchen apparatus that partitions a kitchen and a dining room, and a rising portion 22 that functions as a partition is erected on the back side of the cooking table 2.

  The counter 3 is provided with a sink 5 on one side and a stove 4 on the other side, and an intermediate part of both is a cooking surface part.

  The kitchen device 1 is provided with illumination means 6 for illuminating the counter 3. In this embodiment, the illumination means 6 which makes the left-right direction a longitudinal direction is provided in the upper end part of the standing part 22, and the stove 4, the sink 5, and the cooking surface part between them are illuminated by the illumination means 6. FIG. In addition, although LED is used suitably as a light source of the illumination means 6, it may be an incandescent lamp or a fluorescent lamp, and may be provided not on the rising portion 22 but on the lower surface of the ceiling or the hanging cabinet, It will not be limited if it illuminates the kitchen table 2 suitably. The illuminating means 6 is provided with an operation part (not shown) for manual operation, and the illuminance when illuminating can be changed by operating the operation part.

  The kitchen apparatus 1 is provided with a human body detection sensor 7 for detecting a person approaching the kitchen apparatus 1. In the embodiment shown in FIG. 1, when a person approaches within a predetermined detection area A in front of the cooking table. It is provided on the front end surface of the counter 3 so as to be detected by the human body detection sensor 7.

  The kitchen apparatus 1 is provided with an illuminance sensor 8 that detects brightness (illuminance). In the embodiment shown in FIG. 1, the brightness around the kitchen apparatus 1 (detection area A) is detected. As described above, the brightness on the counter 3 may be detected by the illuminance sensor 8.

  In the present invention, the illuminance illuminated by the illumination means 6 is controlled according to the brightness detected by the illuminance sensor 8, but in this embodiment, two threshold values, a first threshold value and a second threshold value, are used. It is done. FIG. 2 shows a graph showing the correlation of the change in brightness with respect to the time change of the day, each threshold value, and the setting area for each illumination mode. The first threshold is a lower limit of illuminance that is bright enough to illuminate the illumination means 6 and can perform various operations such as cooking without inconvenience, that is, around the cooking table 2 at several hours around noon. The lower limit of illuminance is set. As the second threshold value, the surroundings of the cooking table 2 are hardly illuminated by the light emitted from the outside or the other lights in the room, and of course the cooking operation unit is operated to discharge water from the curan. The upper limit of the illuminance is set such that the work of placing the cup in the sink cannot be easily performed.

  When the human body detection sensor 7 detects a human body and the detection signal is input to the control unit, the brightness detection signal detected by the illuminance sensor 8 is read into the control unit, and the brightness is equal to or higher than the first threshold value. In some cases, the lighting mode I (light-off mode) is executed and the light is not turned on, and when the brightness is less than the first threshold and greater than or equal to the second threshold, the lighting mode II (normal lighting mode) is set. When the main illumination is turned on and the brightness is less than the second threshold, the illumination mode III (low light mode) is executed to perform the non-wake-up lighting.

  The lighting mode I does not light, because when the brightness is equal to or higher than the first threshold, the periphery of the kitchen device is sufficiently bright and does not need to be illuminated by the lighting means 6.

  In the illumination mode II, it is necessary to illuminate with the illumination means 6 when the brightness is less than the first threshold, and when the brightness is more than the second threshold, the work is performed in the kitchen apparatus 1 without being dark like midnight. In order to be suitable, it is illuminated by the illumination means 6 as the main illumination.

  In lighting mode III, when the brightness is below the second threshold, the outside is dark and the lights in the other rooms are also off. For example, at midnight, you get up when you are asleep and drink water with a cup. Since the operation is assumed to be performed, the illumination is performed with an illuminance lower than that of the main illumination so that the user does not wake up.

  In the present invention, when the human body detection sensor 7 detects a human body, the lighting unit 6 controls the illumination unit 6 to illuminate with a predetermined illuminance according to the brightness detected by the illuminance sensor 8. When the surroundings are sufficiently bright, the illumination means 6 does not illuminate, so that the illumination means 6 does not illuminate more than necessary and the user is not dazzled or the power is not wasted.

  In addition, for example, since it is illuminated in the low light mode when it is dark at night, there is no possibility that a user who gets up while sleeping will feel dazzled or wake up and try to sleep again.
