Description

  The present invention relates to a ceiling heating apparatus that emits radiant heat from a ceiling into a room.

  Conventionally, Patent Document 1 discloses that a radiant panel that emits radiant heat into a room is provided on the ceiling and a ceiling fan is provided on the ceiling as radiant heat from the ceiling for comfortable indoor heating.

  In Patent Document 1, a ceiling fan is hung at a position slightly below the center of the ceiling, temperature sensors are provided on the ceiling and the wall, respectively, and a temperature sensor provided on the radiation panel constituting the ceiling and a temperature provided on the wall When the difference in temperature detected by the sensor exceeds a predetermined value, the ceiling fan rotates backward to forcibly send the cold air below to the ceiling, and warm air staying in the area below the ceiling. It is designed to push down.

However, in this conventional example, the ceiling fan is operated when the difference in detected temperature between the temperature sensor provided on the radiation panel constituting the ceiling and the temperature sensor provided on the wall exceeds a predetermined value. . In other words, the difference between the temperature of the radiant panel and the temperature of the room is detected. Therefore, even when warm air does not stay below the ceiling as in the initial stage of the radiant panel heating operation, the temperature of the radiant panel is detected. If the temperature sensor is high, the temperature sensor provided on the radiant panel detects this, and if there is a predetermined temperature difference between the temperature of the radiant panel and the temperature detected by the temperature sensor provided on the wall, the ceiling fan is operated. As a result, there is a problem that air that is not very warm is convected, and air that is not very warm touches a person in the room and feels cold.

  The present invention has been invented in view of the above-described conventional problems, and effectively reduces the lower part of a room based on the temperature difference from the room when warm air stays below the ceiling during ceiling radiant heating. It is an object of the present invention to provide a ceiling heating device that can warm a wall.

The ceiling heating device according to the present invention includes a heating unit 2 that emits radiant heat from the ceiling 1 to the room, a blower unit 3 for sending warm air staying below the ceiling 1 to the lower part of the room, and two temperature sensors 4. 5 The air blowing means 3 is provided on the upper part of the indoor side wall (wall 7), and the two temperature sensors 4 and 5 are the upper and lower parts of the side wall (wall 7) opposite to the side wall on which the air blowing means 3 is provided. Is provided. The direction in which the air blown from the air blowing means 3 is blown out substantially horizontally or obliquely upward toward the side wall provided with the temperature sensors 4 and 5, and two temperature sensors installed on the upper and lower sides of the indoor side wall. When the difference in temperature detected at 4 and 5 becomes larger than the set value, a control unit 6 is provided to control the air blowing means 3 to be turned on.

When the room is heated by heating with the heating means 2 to release radiant heat from the ceiling 1 to the room, there is no unpleasant air flow and the air is not dried, so that comfortable heating can be performed. However, in the case of heating indoors by releasing radiant heat from the ceiling 1 as described above, warm air stays in the upper part of the indoor space, that is, in the vicinity of the lower part of the ceiling 1 . The temperature sensor 4 disposed in the upper part detects the temperature of the air in the upper part of the room, and the temperature sensor 5 disposed in the lower part of the side wall in the room detects the temperature of the air in the lower part of the room. When the difference between the temperature of the upper air in the room and the temperature of the lower air detected in 5 becomes larger than the set value, the air blowing means 3 is turned on, and the warm air staying below the ceiling 1 is sent to the lower part of the room. To warm the lower part of the room and reduce the temperature difference between the upper and lower air in the room.

  Moreover, it is preferable that the ventilation means 3 is the air conditioner 3a.

  By setting it as such a structure, the indoor heating by discharge | release of the radiant heat from the ceiling 1 and the heating by the air conditioner 3a can be used together, or either can be selected and used.

  In the present invention, one of the two temperature sensors is arranged at the upper part of the room below the ceiling and the other one is arranged at the lower part of the room, and the temperature detected by the two temperature sensors. When the difference between the two becomes larger than the set value, the air blowing means is turned on, so that the warm air stays below the ceiling in the ceiling radiant heating, and the temperature difference between the indoor upper air and the lower air When the air pressure exceeds a predetermined value, the air staying in the upper part of the room is lowered to the lower part of the room by the blowing means, the temperature of the lower part of the room is increased to warm the lower part, and the temperature of the upper part of the room is lowered. The temperature difference between the lower part and the lower part can be reduced, and a comfortable heating environment can be obtained. Further, the warm air staying in the upper part can be lowered by the blowing means as described above, and the temperature of the upper part can be lowered. The temperature of the surface of the Heat radiation Inetsu is able to perform efficiently, the ceiling radiation heating for the entire room can be performed effectively.

  In addition, when the air blowing means is an air conditioner, it is possible to use both indoor heating by releasing radiant heat from the ceiling and heating by the air conditioner, or by selecting either one and using it easily. The optimum heating according to the purpose can be selected by the configuration.

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

  The ceiling 1 is provided with heating means 2 for generating radiant heat in the room and heating the room. In the embodiment shown in FIG. 1, the ceiling 1 is configured by the ceiling panel 1 a having heating means 2 such as an electric heater, so that the room can be heated by releasing radiant heat from the ceiling 1 into the room. It has become.

  The air blowing means 3 is provided on the upper part of an arbitrary wall 7 in the room.

  Two temperature sensors 4 and 5 are provided in the room. One temperature sensor 4 out of the two temperature sensors 4 and 5 is arranged in the upper part of the room below the ceiling 1 and detects the temperature of the air in the upper part of the room. The other temperature sensor 5 is arranged in the lower part of the room and detects the temperature of the air in the lower part of the room.

  The two temperature sensors 4 and 5 are attached to the wall 7. In the embodiment shown in the accompanying drawings, two temperature sensors 4 and 5 are provided on the upper and lower portions of the wall 7 facing the wall 7 provided with the air blowing means 3. Further, an infrared transmission section 9 is provided on the upper portion of the wall 7 facing the wall 7 provided with the air blowing means 3 so as to face the air blowing means 3. The wall 7 is provided with a controller 8 having a control unit 6 and a relay unit 10. And by operating the operation part provided in the controller 8, the heating means 2 is controlled via the relay unit 10, and the air blowing means 3 is controlled via the infrared transmission part 9.

  In the present invention, by turning on the heating means 2, radiant heat can be emitted from the ceiling 1 into the room to heat the room.

  Here, in the case of heating indoors by emitting radiant heat from the ceiling 1, since warm air is light, it stays in the upper part of the indoor space, that is, near the lower part of the ceiling 1, so the temperature of the air in the upper part of the room The difference between the temperature of the air and the temperature of the air in the lower part gradually increases, and a part close to the ceiling 1 such as a person's head or face feels unpleasant, or the feet feel cold.

Therefore, in the present invention, the temperature of the air in the upper part of the room is detected by the temperature sensor 4 arranged in the upper part of the room, and the temperature of the air in the lower part of the room is detected by the temperature sensor 5 arranged in the lower part of the room. enter the temperature information detected by the two temperature sensors 4, 5 to the control unit 6, the difference between the upper Symbol two upper in a room detected by the temperature sensor 4 and 5 of the air temperature and the temperature of the bottom of the air When it becomes larger than the set value, the control unit 6 performs control to turn on the air blowing means 3.

When the blower 3 is turned on, warm air staying below the ceiling 1 is sent to the lower part of the room, warming the lower part of the room, and reducing the temperature difference between the air in the upper part and the air in the lower part of the room.

As described above, according to the present invention, the temperature sensor 4 detects the temperature of the air in the upper part of the room, and the temperature sensor 5 arranged in the lower part of the room detects the temperature of the air in the lower part of the room. 4 and 5 detects the temperature difference between the upper air and the lower air in the room, so that warm air does not stay below the ceiling 1 and the surface temperature of the ceiling 1 is high by the heating means 2. for such that not much difference in temperature between the upper part of the air and lower air, not air blowing means 3 because it is desirable heating in from oFF to oN, it is possible to continue the desired heating operation, the ceiling 1 below If warm air stays in the room and the temperature difference between the air in the upper part and the air in the lower part exceeds a predetermined value, there is a feeling of discomfort such as a hot flash. is there.

  Further, as shown in the attached drawings, the air blowing means 3 is provided on the upper portion of an arbitrary wall 7, and two temperature sensors 4, 5 are provided on the upper and lower portions of the wall 7 facing the wall 7 on which the air blowing means 3 is provided. Thus, warm air stays below the ceiling 1, and when the air blowing means 3 is turned on as described above, the air blown by the air blowing means 3 flows from the upper side of the wall 7 provided with the air blowing means 3. The warm air staying below the ceiling 1 flows from the upper side to the lower side of the wall 7 provided with the two temperature sensors 4. It will descend and warm the lower part of the room. In this case, the last part of the warm air staying below the ceiling 1 moved by the air blowing means 3 goes down through the vicinity of the upper temperature sensor 4, and therefore the last part of the warm air staying there passes through. In other words, the upper temperature sensor 4 detects this as soon as the warm air stays below the ceiling 1, and the temperature difference between the upper air in the room and the lower air by the two temperature sensors 4, 5 is detected. Since it becomes small, the ventilation means 3 can be automatically turned off. Thereby, even after the warm air staying in the upper side is lowered, a downward flow having a relatively low temperature is generated along the wall 7 on the side where the temperature sensors 4 and 5 are provided by the blowing of the blowing means 3. And no discomfort can occur.

  In addition, it is preferable that the blowing direction of the air blown from the blowing means 3 is substantially horizontal or an oblique direction upward from the horizontal. In particular, assuming an oblique direction upward from the horizontal, it is possible to follow the entire width from one end portion of the ceiling 1 to the other end portion, and the warm air staying in the entire area below the ceiling 1 The lower part of the room can be warmed by descending from the upper part to the lower part along the opposing wall 7.

  Further, when the direction of the air blow from the air blowing means 3 is an oblique direction upward from the horizontal, the air is blown over the entire width from one end of the ceiling 1 to the other end as described above. Since the warm air staying along can be sent to the lower part of the room, the warm air does not stay in the corner part formed by the ceiling 1 and the wall 7 and the temperature difference between the lower part and the upper part of the room more reliably. Can be reduced.

  Note that when the air blowing means 3 is turned on, the heating means 2 is switched from on to off at the same time, and further, the controller 6 is turned on again from the time when the air blowing means 3 is turned off and at the same time the heating means 2 is turned on again. You may make it control by.

  Further, when switching the air blowing means 3 from on to off, it may be automatically switched from on to off when the temperature difference between the temperatures detected by the two temperature sensors 4 and 5 falls below a predetermined value. Alternatively, it may be controlled to automatically switch from on to off when a predetermined time (for example, several minutes) elapses after the air blowing means 3 is turned on.

  The air blowing means 3 may be one that only blows room air without a temperature adjustment function, or may be an air conditioner 3a having a temperature adjustment function for room air.

  When the air blower 3 is composed of the air conditioner 3a, the room heating by the radiation of the radiant heat from the ceiling 1 by the heating means 2 and the heating by the air conditioner 3a are used in combination, or one of them is selected. Can be used. Further, when the indoor heating is performed by the radiation of the radiant heat from the ceiling 1 by the heating means 2, if the warm air stays in the vicinity of the lower portion of the ceiling 1 as described above, the air conditioner 3a which is the blowing means 3 is turned on. Thus, the warm air staying by causing an air flow from one end of the ceiling 1 to the other end can flow to the lower part of the room. At this time, the air blown from the air conditioner 3a toward the ceiling 1 is selected between the case where the room air is blown without adjusting the temperature and the case where the room air is heated by the air conditioner 3a and blown. You may be able to do it, By doing in this way, more various heating forms according to a situation can be selected.

It is a schematic block diagram of this invention.
