Description

  The present invention relates to a ceiling heating device.

  Conventionally, what is shown by patent document 1 is known as a heating system which heats a ceiling and heats a room | chamber interior.

  The conventional example shown in the above-mentioned patent document 1 includes an infrared sensor for dividing a ceiling into a plurality of heating areas and detecting a person in the room. When there is a person in the room, the infrared sensor uses a plurality of heating ceilings. Energy is detected by detecting which heating area is below the heating area, heating the heating ceiling area where it is detected that there is a person, and preferentially heating the heating area where there is a person below. It tries to reduce the loss and heat the room.

  By the way, in the above-mentioned conventional example, when a person lies down and sleeps or lies down and takes a rest, the heating area where the person's face or head is positioned below is preferentially heated and heated. Until the room temperature reaches a predetermined temperature, the face or head is heated preferentially by the radiant heat from the heating area, and the face or head becomes hot and becomes uncomfortable.

  Also, when a person is lying down and sleeping, the face and head do not want to shine, but the foot side far from the face can sleep more comfortably when warmed earlier, but in the conventional example above Because the heating area where the person is detected with the infrared sensor is preferentially heated and heated, when a person lying down across the plurality of heating areas is detected, the corresponding heating areas are set under the same conditions. Because it heats preferentially, both the foot side and face or head side will be heated and heated under the same conditions, such as heating and heating the foot side preferentially while eliminating the burning of the face and head. There was a problem that I could not.

As a result, in the heating by the ceiling heating device disclosed in Patent Document 1, there is a problem in that a comfortable sleep when lying down or a comfortable break when lying down cannot be performed.

  The present invention has been invented in view of the above-mentioned conventional problems, and is effective while suppressing a burning sensation on the face and head when lying down indoors and sleeping or lying down. In particular, it is an object of the present invention to provide a ceiling heating apparatus that can heat a room to a predetermined room temperature.

  The ceiling heating apparatus according to the present invention detects the face 4 or head of a person in the room 2 by dividing the ceiling 1 into a plurality of heating areas 3 in a heating system that heats the ceiling 1 and heats the room 2. Each heating area 3 based on the detection means 5 and the detection result of which heating area 3 of the plurality of heating areas 3 the face 4 or the head of the person in the room 2 is located by the detection means 5. The control part 6 which performs heating control of is provided. Then, in the present invention, as the heating control mode by the control unit 6, the face 4 or the head is farthest from the heating area 3 where the face 4 or the head is positioned based on the detection result of the human face 4 or the head by the detection means 5. When heating of the heating area 3 is started and reaches a predetermined room temperature within a predetermined time, control is performed to continue heating only of the heating area 3 away from the heating area 3, while the predetermined room temperature is reached within the predetermined time. If it does not reach, the heating area 3 to be heated is characterized by having a heating control mode in which the heating area 3 is controlled so as to gradually spread to the side approaching the human face 4 or head.

  By adopting such a configuration, when the room 2 is heated when lying down or sleeping in the room 2 or lying down, as described above, the human face 4 or head by the detection means 5 is used. The heating area 3 where the face 4 or head is located is detected based on the detection result indicating which heating area 3 the face 4 or head is located below. When heating of the heating area 3 farthest from 3 is started and the predetermined room temperature is reached within a predetermined time, only heating of the heating area 3 furthest away from the person's face 4 or head is performed. . Thereby, the room 2 can be heated while eliminating the burning of the face 4 or the head by radiation heating from the ceiling 1. If heating of the heating area 3 farthest from the face 4 or the head is started and the predetermined room temperature is not reached within a predetermined time, the heated heating area 3 approaches the human face 4 or the head. By controlling so as to spread gradually to the side, the room 2 can be heated while suppressing the burning of the face 4 or the head by radiant heating from the ceiling 1.

  In addition to the heating control mode (hereinafter referred to as the first heating control mode) as a heating control mode by the control unit 6, as another heating control mode, the human face 4 or head by the detection means 5 is used. On the basis of the detection result, heating of the heating area 3 where the face 4 or the head is located below is started, and if the predetermined temperature is reached within a predetermined time, the heating area 3 where the face 4 or the head is located below On the other hand, if the predetermined room temperature is not reached within a predetermined time, the heated heating area 3 is gradually expanded to the side away from the face 4 or the heating area 3 where the head is located below. It is preferable to provide a mode switching means 7 that has a heating control mode (hereinafter referred to as a second heating control mode) for performing control and that selects and operates the two heating control modes.

  By adopting such a configuration, as described above, when the room 2 is heated when lying down or sleeping or lying down and taking a break, the mode switching means 7 performs the first heating. By operating by selecting the heating mode, the room 2 can be heated while suppressing the burning of the face 4 and the head in the radiant heating by heating the ceiling 1. On the other hand, when the room 2 is heated while sitting on a chair or the floor or standing up in the room 2, the second heating / heating mode is selected by the mode switching means 7 and the ceiling 1 is operated. In the radiant heating with heating, the heating area where a person is present can be preferentially heated so that the heating area where the person is present can be effectively heated while saving energy.

  Since the present invention is configured as described above, it is possible to effectively set the room temperature to a predetermined room temperature while suppressing the feeling of burning of the face and head while lying down in the room or sleeping or lying down. It can be heated so that you can sleep comfortably lying down and have a comfortable break lying down.

  In addition, for those equipped with two heating and heating modes, heating suitable for lying down indoors, sleeping, lying down, resting on a chair or floor, or standing up. You can choose a suitable heating when you are.

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

  The present invention relates to a heating system that heats the room 2 by providing heating means 9 on the ceiling 1 and releasing radiant heat from the surface of the ceiling 1 into the room 2.

  In the present invention, in such a heating system that heats the ceiling 1 and heats the room 2, the ceiling 1 is divided into a plurality of heating areas 3, and heating means 9 is provided in each of the divided heating areas 3. It is provided. As the heating means 9, an electric heater, a heating means by hot water circulation or the like can be adopted. Each heating means 9 is controlled by the control unit 6.

  In the present invention, the face 4 or the head of a person in the room 2 is detected, and the detected face 4 or head is detected below the heating area 3 among the plurality of heating areas 3 or Detection means 5 for detecting whether the head is present is provided.

  As an example of the detection means 5, for example, an infrared camera can be used, a person in the room 2 is detected with the infrared camera, and further, a determination means provided in the control unit 6 is used with the infrared camera. The shape of the captured face 4 or head is determined, and the heating area 3 below the plurality of heating areas 3 is detected. In the case of an infrared camera, it is possible to detect the face 4 or the head of a person who is in the room 2 (of a person sleeping in the room 2 at night) even at night when the illumination is turned off.

  The control mode by the control unit 6 includes at least two heating control modes of a first heating control mode and a second heating control mode described below.

  In the first heating control mode, the detection means 5 detects the human face 4 or the head, and based on the result, the face 4 or the head is below the heating area 3 among the plurality of heating areas 3. The heating area 3 is detected based on the detection result of the face 4 or the head, and heating of the heating area 3 farthest from the heating area 3 where the face 4 or the head is positioned below is started. When the predetermined room temperature is reached, control is performed to continue heating only the heating area 3 away from the heating area 3. On the other hand, if the predetermined room temperature is not reached within the predetermined time, the heated heating area 3 is This is a heating control mode in which control is performed so that the face 4 or the head closer to the head also spreads sequentially.

  In the second heating control mode, heating of the heating area 3 in which the face 4 or the head is positioned below is started based on the detection result of the human face 4 or the head by the detecting means 5 and is predetermined within a predetermined time. If the room temperature is reached, control is performed to continue heating only the heating area 3 where the face 4 or the head is located below. On the other hand, if the room temperature is not reached within a predetermined time, the heating area 3 to be heated is 4 or a heating control mode in which control is performed so that the head is gradually extended to the side away from the heating area 3 where the head is positioned below.

  The first heating control mode and the second heating control mode are switched by the mode switching means 7 so that the operation can be performed in the target heating control mode.

  When lying down in the room 2 or sleeping or lying down, the first heating control mode is set and heating is performed. In this case, the detection means 5 detects the human face 4 or head, and detects the heating area 3 where the detected face 4 or head is present, and under which heating area 3 the face 4 or head is located. Based on the detection result of whether it is located, the heating of the heating area 3 farthest from the heating area 3 where the face 4 or the head is positioned below is started.

  In the embodiment shown in FIG. 1, an example in which the detection unit 5 detects that the face 4 or the head is present below the heating area 3 a among the plurality of heating areas 3 (3 a, 3 b, 3 c, 3 d). When the detection means 5 detects that the face 4 or the head is present below the heating area 3a, the heating means 9 in the heating area 3d farthest from the heating area 3a is turned on. Then, the heating area 3d is heated, and the room 2 is controlled to be radiantly heated at the heating area 3d portion of the ceiling 1.

  Control that continues heating only the heating area 3d farthest away from the person's face 4 or head if the room temperature reaches a predetermined temperature within a predetermined time from the start of heating of the heating area 3d farthest away. To control the room temperature to keep a predetermined temperature.

  In addition, when heating of the heating area 3d is started and the predetermined room temperature is not reached within a predetermined time, the heating area 3 to be heated is controlled so as to gradually spread to the side close to the human face 4 or head. . That is, in the embodiment shown in FIG. 1, the heating of the heating means 9 provided in the heating area 3c is started while the heating of the heating means 9 in the heating area 3d is continued.

  Then, in addition to the heating of the heating area 3d, if the heating reaches the predetermined temperature within a certain period of time after the heating of the heating area 3c is reached, a control is performed to continue heating only the heating areas 3d and 3c. Control to maintain a predetermined temperature.

  Further, when heating of the heating area 3c is started and the predetermined room temperature is not reached within a predetermined time, the heating means 9 provided in the heating area 3b is continued while continuing to heat the heating means 9 in the heating areas 3d and 3c. Start heating.

  Then, in addition to the heating of the heating areas 3d and 3c, when the heating reaches the predetermined temperature within a certain period of time after the heating of the heating area 3b is started, the control for continuing only the heating of the heating areas 3d, 3c and 3b is performed. And control to keep the room temperature at a predetermined temperature.

  Furthermore, when heating of the heating area 3b is started and the predetermined room temperature is not reached within a predetermined time, the heating provided in the heating area 3a is continued while continuing the heating of each heating means 9 in the heating areas 3d, 3c, and 3b. The heating of the means 9 is started and the room temperature is controlled to be a predetermined temperature.

  Thus, in the radiant heating from the ceiling 1, the heating area 3d farthest from the place where the face 4 or the head is located is heated to heat the room 2, so the radiant heating from the ceiling 1 causes the face 4 to be heated. Or the room 2 can be heated while eliminating or suppressing the burning of the head. In particular, when the body lying in the room 2 is located below the plurality of heating areas 3, the face 4 or the foot side away from the head is preferentially heated first. Heating and heating can be performed preferentially from the foot side while eliminating the burning of the head, and it is possible to realize heating of the room 2 that allows comfortable sleep.

  Further, when the room 2 is heated while sitting on a chair or a floor or standing in the room 2, the mode switching means 7 selects the second heating / heating mode and performs the heating operation.

  In this case, the detection means 5 detects the human face 4 or head, and detects the heating area 3 where the detected face 4 or head is present, and under which heating area 3 the face 4 or head is located. Heating of the heating area 3 where the face 4 or the head is positioned below is started based on the detection result of whether it is located.

  In the embodiment shown in FIG. 2, an example in which the detection unit 5 detects that the face 4 or the head is present below the heating area 3 a among the plurality of heating areas 3 (3 a, 3 b, 3 c, 3 d). When the detection means 5 detects that the face 4 or the head is present below the heating area 3a, the heating means 9 in the heating area 3a is turned on to heat the heating area 3a. Then, control is performed so that the radiant heating of the room 2 is performed in the heating area 3 portion of the ceiling 1.

  If the room temperature reaches a predetermined temperature within a predetermined time from the start of heating the heating area 3a where the face 4 or the head is present below, control is performed to continue heating only the heating area 3a. Control to keep temperature.

  Further, when heating of the heating area 3a is started and the predetermined room temperature is not reached within a predetermined time, the heating area 3 to be heated is controlled so as to gradually spread to the side away from the human face 4 or the head. That is, in the embodiment shown in FIG. 2, heating of the heating means 9 provided in the heating area 3b is started while continuing heating of the heating means 9 in the heating area 3a.

  Then, in addition to the heating of the heating area 3a, if the heating reaches the predetermined temperature within a certain period of time after the heating of the heating area 3b is reached, control is performed to continue heating only of the heating areas 3a and 3b. Control to maintain a predetermined temperature.

  Furthermore, when heating of the heating area 3b is started and the predetermined room temperature is not reached within a predetermined time, the heating means 9 provided in the heating area 3c is continued while continuing the heating of the heating means 9 in the heating areas 3a and 3b. Start heating.

  Then, in addition to the heating of the heating areas 3a and 3b, when the heating reaches the predetermined temperature within a certain time after the heating of the heating area 3c is reached, the control of continuing only the heating of the heating areas 3a, 3b and 3c is performed. And control to keep the room temperature at a predetermined temperature.

  Furthermore, if heating of the heating area 3c is started and the predetermined room temperature is not reached within a predetermined time, the heating provided in the heating area 3d is continued while continuing the heating of the heating means 9 in the heating areas 3a, 3b, 3c. The heating of the means 9 is started and the room temperature is controlled to be a predetermined temperature.

  Thus, in the radiant heating from the ceiling 1, the room 2 is heated in order from the heating area 3 d side where the face 4 and the head are located. Heating area 3 is preferentially heated, and a place where a person is in room 2 can be preferentially heated while saving energy.

  Here, when sitting on a chair or floor in the room 2 or standing, the position of the face 4 or head and the position of other parts of the body are located at substantially the same position in plan view. By detecting which heating area 3 the face 4 or the head is located below by the detection means 5, it is known which heating area 3 the person is below, and heating in the second heating control mode is performed. The lower part of the heating area 3 where the whole body is located can be effectively heated by driving.

  Of course, in the present invention, in addition to the two heating control modes of the first heating operation control mode and the second heating operation control mode as the heating operation mode, the heating means 9 in all the heating areas 3 are simultaneously heated.
