Abstract

PURPOSE:To perform a comfortable heating with an energy saving even in such a space where a person is present for a relatively short period of time by a method wherein a radiation surface control is carried out in response to a sensed data detected by a human body surface temperature sensing mean: and an occupant position sensing means. CONSTITUTION:In the event that no person is present in a room 5, a presence of a person in the room 5 is not detected by a human body surface temperature sensing means 1, resulting in that a radiation surface 3 at an initial starting position is kept OFF and a radiation heating is not carried out. In the event that there is a person in the room 5, the human body surface temperature sensing means 1 detects that there is a person in the room 6 and further detects the human body surface temperature. In the even. that the human body surface temperature is 33 deg.C or above a radiation panel constituting a radiation surface 3 is turned off. However, in the event that the human body surface temperature is 33 deg.C or below a distance between it and a human body is calculated by the occupant position sensing means 2 to detect a human body position. The most appropriate radiation surface of a plurality of divided radiation surfaces 3a, 3b and 3c is selected in response to the detection of the human body position, the radiation panel selected and constituting the radiation surface is turned on to perform a radiation heating.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to comparatively small rooms where no one is usually present, such as a toilet room, a changing room, or an entrance, and where there are no occupants at all times. The present invention relates to a radiant heating device that can improve the comfort of indoor spaces even when the space is short.

[Prior art 1] Because people spend only a short time in toilet rooms, changing rooms, entrances, etc., heating and cooling, including air conditioning, is generally not performed. This is quite a burden in terms of equipment costs and running costs, and since the room is only open for a short time when the room is occupied, there is no suitable heating system, so it is necessary to Currently, there is no heating system.

In addition, a general radiant heating device measures the room temperature and controls the radiant heating device, but two methods are mainstream: measuring the temperature of the radiant surface and controlling the radiant heating device. Therefore, no information on the human body is taken into consideration, and the temperature setting must be done by the person himself, which is inconvenient. Furthermore, energy efficiency is also poor because heating is applied to areas where no one is present.

[Problem to be solved by the invention 1] However, because toilet rooms, changing rooms, entrances, etc. do not have heating devices, they are extremely cold and uncomfortable in winter, which is not good for both health and comfort. Furthermore, even if conventional heating equipment were installed, there was a problem that the energy efficiency was poor and there was a lot of waste compared to the cost. Also, for example, when comparing radiant heating and convection heating, radiant heating is theoretically more effective at warming people up quickly, and radiant heating can be said to be more suitable for heating the above-mentioned rooms. ,
In the past, radiant heating had not been effectively controlled.

The present invention was invented in view of the problems of the conventional methods described above, and its purpose is to provide a radiant heating system that can provide energy-saving and comfortable heating even in spaces where people are only present for a relatively short time. Located in providing heating equipment.

[Means for Solving the Problems 1] The radiant heating device of the present invention is a radiant heating device for heating a room, and includes a human body surface temperature detection means 1 for detecting the human body surface temperature of a person in the room; a control means 4 for controlling the radiation surface 3 based on detection data detected by the human body surface temperature detection means 1 and the occupant position detection means 2; By employing such a configuration, the above-mentioned problems of the conventional example are solved and the object of the present invention is achieved.

1 Effect 1 Therefore, the human body surface temperature and the position of the human body are detected by the human body surface temperature detection means 1 and the room occupant position detection means 2,
Based on this data on the human body surface temperature and the position of the human body, the radiant surface 3 is controlled by the controller ri4 to perform the most optimal radiant heating according to the situation.

[Example 1] The present invention will be described in detail below based on an example shown in the accompanying drawings.

#S1 shows a schematic diagram of the radiant heating device of the present invention. In the embodiment, the room 5 to be radiantly heated by the radiant heating device is, for example, a toilet room, a changing room, an entrance, or other relatively small room where the occupant stays for a short time. The radiant heating device that radiantly heats the room 5 includes a human body surface temperature detection means 1 that detects the surface temperature of the human body when there is a person in the room 5, and a person position detector that detects the position of the person in the room. Means 2
and a control means 4 for controlling the radiation surface 3 based on the detection data detected by the human body surface temperature detection means 1 and the occupant position detection means 2. In the embodiment shown in FIG. 1, a human body surface temperature detecting means 1 for detecting the human body surface temperature of the person in the room and a person position detecting means 2 for detecting the position of the person in the room are provided on the ceiling 6 of the room 5. A radiant panel serving as a radiating surface 3 is provided on the wall 7 of the room 5, and this radiating panel has a plurality of radiating surfaces 3a, 3b,
3c... For example, as shown in FIG. 2, the radiation surface 3 is vertically divided into a plurality of radiation surfaces 3a,
When divided into 3b and 3c, radiation surfaces 3a, 3b, 3C
When a person is sitting, radiant heating is performed by turning on only the lower radiant surface 3c or the middle and lower radiant surfaces 3b and 3c, and when a person is standing, the radiant heating is performed on the upper, middle, and lower radiant surfaces 3.
A, 3b, and 3c are turned on to perform radiant heating to save energy. Of course, it may be divided into a plurality of radiation surfaces in the horizontal direction. Here, the human body surface temperature detection means 1 uses an infrared sensor, and is used to detect the presence of a person in the room 5 and to detect the temperature of the surface of the human body. In other words, this human body surface temperature detection means 1 serves both to detect the human body surface temperature and to detect whether there is a person in the room. As the room occupant position detection means 2, for example, an ultrasonic sensor is used.

The human body surface temperature detecting means 1, the room occupant detecting means 2, and the radiation panel constituting the radiation surface 3 are connected to a controller constituting the control means 4 by a signal line 10. M in FIG. 1 indicates a person. FIG. 3 shows a control block diagram of the radiant heating apparatus of the present invention, in which the control means 4 collects body surface temperature data detected by the human body surface temperature detection means 1 and the occupant position detection means 2, and the position of the occupant. It is composed of an arithmetic processing section 7 for inputting data and processing this data, and a radiation surface control section 8 for controlling the radiation surface 3 divided into a plurality of parts based on the signal from the arithmetic processing section 7. .

Incidentally, it is known that there is a close relationship between human body surface temperature and thermal comfort, and it is said that a human body surface temperature of around 33° C. is comfortable. The present invention aims to provide a sense of comfort by controlling radiant heating based on this temperature, and if the human body surface temperature detected by the human body surface temperature detection means 1 is 33°C or lower, the radiant heating The setting is such that the radiant panel that makes up the radiation surface 3 is turned on, and if the temperature exceeds 33°C, the @manufacturer panel that makes up the radiation surface 3 is turned off. Also,
In order to achieve energy saving, the position of the person in the room is detected by the person position detection means 2, and a plurality of radiation surfaces 3a, 3b, 3
Energy saving can be achieved by selecting which of c is on and which is off.

FIG. 4 shows a flowchart showing the operation of the radiant heating apparatus of the present invention. Next, the operating operation of the present invention will be explained based on the chart 70 in FIG.

If there is no person in the room 5, the human body surface temperature detection means 1 does not detect that there is a person in the room 5, and therefore the initial starting position (radiant heating is being performed with the radiant surface 3 turned off) is not detected. If there is a person in the room 5, the human body surface temperature detection means 1 detects the presence of the person and also detects the surface temperature of the human body.

When the surface temperature of the human body is 33°C or higher, the radiant panel constituting the radiant surface 3 is turned off, but when the surface temperature of the human body is 33°C or lower, the occupant position detection means 2 detects the human body. The radiation surfaces 3a and 3b are divided into a plurality of parts based on the detection of the human body position.
, 3c is selected, and the radiant panel constituting the selected radiant surface is turned on to perform radiant heating. While the presence of a person is detected, if the surface temperature of the human body is below 33°C, the system will turn on the optimal radiant surface in the same order and continue radiant heating, and if the surface temperature of the human body is above 33°C. In this case, the radiant panel constituting the radiant surface 3 is turned off, and on the other hand, when there is no person from the section M5 during radiant heating by the radiant surface 3, the human body surface temperature detection means 1 is turned off.
detects that no one is present, turns off the radiant panel constituting the radiant surface 3, and assumes the starting position.

[Effects of the Invention] As described above, the present invention provides a radiant heating device for heating a room, which includes a human body surface temperature detection means for detecting the body surface temperature of a person in the room; Since it is equipped with a room occupant position detection means for detecting the position, a human body surface temperature detection means, and a control means for controlling the radiation surface based on the detection data detected by the room occupant position detection means, the human body The surface temperature detection means and the occupant position detection means detect the human body surface temperature and the position of the human body, and the control means controls the radiation surface based on the data of the human body surface temperature and the human body position. It is possible to perform the most optimal radiant heating depending on the occasion, and as a result, it is possible to perform energy-saving and comfortable heating even in spaces where people are only present for a relatively short time.
