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 the detected temperature in the temperature sensor provided on the ceiling and the temperature sensor provided on the wall is When the specified value is exceeded, the ceiling fan rotates backward to forcibly send the cold air below to the ceiling and push the warm air staying in the area below the ceiling downward. ing.

  However, in this conventional example, the warm air staying in the part where the ceiling fan is provided in the central part of the ceiling and the cold air in the central part of the room below the ceiling fan are simply replaced. There is a problem that warm air staying below the remote ceiling cannot be effectively flowed downward, and heat tends to be trapped near the lower end of the ceiling.

  Moreover, the cold air in the room rises toward the ceiling fan side below the ceiling fan, that is, in the center of the room. However, the central part of the room is an area where there is a high probability that there is a person in the room, and an upward flow of cold air is generated as described above during heating in an area where the person is most likely to exist. Thus, there is a problem that this cold upward flow gives the person in the center of the room a cold feeling.

  Further, in the above conventional example, since the ceiling fan is suspended from the ceiling, the radiation heating panel cannot be provided at the ceiling part where the ceiling fan is suspended, and the arrangement position of the radiation panel is restricted. There is a problem, and since it is not possible to provide a radiant panel at the center of the ceiling corresponding to the center of the room where there is a high probability that there will be people, when warming the room with radiant heat from the ceiling, There is a problem that it cannot be effectively warmed.

Further, Patent Document 2 is known as another conventional example. In this Patent Document 2, a radiation duct is arranged on the back of the ceiling, a ceiling is formed by a radiation panel constituting the lower surface of the radiation duct, and a downstream end of the radiation duct is connected to an outlet formed on the ceiling. . Then, heated air, which is heated from the air inlet through the heat exchanger, emits radiant heat through the radiant duct from the radiant panel on the bottom of the radiant duct to the room. The room is heated by the combined use. Also, if warm air stays below the ceiling, it is not heated by the heat exchanger, but stays below the ceiling simply by blowing out air from the air outlet through the radiant duct into the room. However, the stagnation in this case is that the air circulates and convects in the circulation path of the room → the inlet provided in the ceiling → the radiation duct → the outlet → the room. There is a problem that the air hardly flows along the lower surface of the ceiling, and the warm air staying below the ceiling is effectively reduced to make it difficult to move the heat to the lower part of the room.

  The present invention has been invented in view of the above-mentioned conventional problems, and effectively eliminates the stay when warm air stays under the ceiling in indoor heating by radiant heat from the ceiling. It is an object of the present invention to provide a ceiling heating device that can warm the lower part of the room and that does not generate an upward flow of cold air in the substantially central part of the room and can perform comfortable room heating by radiant heat from the ceiling. To do.

  The ceiling heating apparatus according to the present invention includes a heating unit 2 that emits radiant heat from the ceiling 1 into the room, and a blower unit 3 that blows air along the ceiling 1. And the present invention is characterized in that the air blowing means 3 is provided on the upper part of the wall 4 and the direction of the air blowing from the air blowing means 3 is an oblique direction upward from the horizontal. .

  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 in this way, warm air stays in the upper part of the indoor space, that is, near the lower part of the ceiling 1. Since the air blowing means 3 for blowing air is provided, the warm air staying near the lower portion of the ceiling 1 can be moved downward in the room by operating the air blowing means 3 and blowing air along the ceiling 1. . Moreover, since the air blowing means 3 is provided on the upper portion of the wall 4 and the direction of the air blown from the air blowing means 3 is an oblique direction upward from the horizontal, one end of the ceiling 1 It is possible to follow the entire width from one end to the other end, and the warm air staying in the entire area below the ceiling 1 is lowered along the other opposing wall 4 from the upper part to the lower part to warm the lower part of the room. The lower cold air can rise along the wall 4 toward the blowing means 3 side. In addition, since the wind flows while reliably contacting the surface of the ceiling 1, the warm air staying below the ceiling 1 can be lowered along the wall 4 as described above, and the convective heat transfer coefficient of the ceiling 1 is increased. Therefore, the heat radiation from the ceiling 1 is promoted, the temperature of the surface of the ceiling 1 can be lowered, and the heat accumulated below the ceiling 1 can be efficiently lowered in a short time.

  Moreover, it is preferable to provide the control part 5 which controls so that the ventilation means 3 may be turned ON simultaneously with switching operation of the heating means 2 from ON to OFF.

  When the heating means 2 is turned on and radiant heat is emitted from the ceiling 1 into the room to heat the room, warm air stays near the lower part of the ceiling 1 over time. Thus, when warm air stays in the vicinity of the lower part of the ceiling 1, the operation of the heating means 2 is switched from ON to OFF, and at the same time, the warm air staying in the vicinity of the lower part of the ceiling 1 is turned on along the wall 4. Lower. Thereby, while the temperature of the surface of the ceiling 1 and the vicinity of the lower part of the ceiling 1 falls, warm air falls to the lower part of the room, and the lower part of the room can be effectively heated.

  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, the air blowing means is provided on the upper part of the wall, and the direction of the air blown from the air blowing means is an oblique direction upward from the horizontal, so that the lower part of the ceiling is radiated from the ceiling. Even if warm air stays in the vicinity, by turning on the air blowing means and blowing air along the ceiling, the temperature of the ceiling surface is lowered, the feeling of fire is mitigated, and the warm air staying near the bottom of the ceiling is It is possible to lower the temperature along the wall to reduce the temperature difference between the upper part and the lower part of the room and to display a comfortable room temperature environment. In addition, since the direction of the air blowing from the blowing means is an oblique direction upward from the horizontal, the warm air staying near the lower part of the ceiling is lowered along the wall facing the blowing means, A convection that raises the cool air in the lower part of the room along the wall provided with the air blowing means is formed, and the heat staying under the ceiling is efficiently lowered in a short time to prevent the fire due to the ceiling radiation heating and the conventional As described above, an upward flow of cold air does not occur in the substantially central portion of the room, and the influence on the people in the room can be reduced, and comfortable room heating can be performed by radiant heat from the ceiling.

  In addition, by providing a control unit that switches the operation of the heating means from on to off and at the same time turns on the blower means, the temperature of the ceiling surface and the vicinity of the lower part of the ceiling are effectively lowered, and the indoor The lower part can be effectively heated, and the temperature difference between the upper part and the lower part of the room can be reduced, and a comfortable indoor temperature environment can be realized.

  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 4 in the room. The blowing direction of the wind from the blowing means 3 provided on the upper portion of the wall 4 is an oblique direction upward from the horizontal so as to move away from the wall 4 as it goes upward.

  In addition, when the air blowing direction from the air blowing means 3 provided on the upper portion of the wall 4 is horizontal or obliquely downward, the air can flow along almost the entire width of the surface of the ceiling 1 as described above. However, even if the air is blown, a staying portion where air does not flow is generated on the surface of the ceiling 1 and a corner portion formed by the ceiling 1 and the wall 4, which is not preferable.

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

  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 the room by releasing radiant heat from the ceiling 1, the warm air is light and therefore stays in the upper part of the indoor space, that is, in the vicinity of the lower part of the ceiling 1. The difference gradually increases, and parts close to the ceiling 1 like a human head and face are lit up. Therefore, in the present invention, when warm air stays in the vicinity of the lower portion of the ceiling 1, the air blowing means 3 is turned on and the air is blown from the air blowing means 3 toward one end of the surface of the ceiling 1 as indicated by the arrow a in FIG. Sprayed from an oblique direction, then blows along the surface (lower surface) of the ceiling 1 from one end side to the other end side of the ceiling 1 as indicated by the arrow b in FIG. 1, the warm air staying in the whole area near the lower part of the ceiling 1 is lowered along the wall 4 facing the air blowing means 3 to flow downward as shown in FIG. Can warm up.

  In this case, since the air blowing means 3 is provided on the upper part of the wall 4 and the direction in which the air blows from the air blowing means 3 is an oblique direction upward from the horizontal, one end of the ceiling 1 It is possible to follow the entire width from one end to the other end, and the warm air staying in the entire area below the ceiling 1 is lowered along the other opposing wall 4 from the upper part to the lower part to warm the lower part of the room. be able to.

  On the other hand, as described above, the air blowing means 3 provided on the upper portion of one wall 4 is turned on, and the air is blown from the air blowing means 3 obliquely toward one end of the surface of the ceiling 1 as indicated by the arrow a in FIG. When attached, the cold air in the lower part of the room rises from the lower part toward the upper air blowing means 3 side along the wall 4 provided with the air blowing means 3. The cold air in the lower part of the room rises from the lower part to the upper part along the wall 4 provided with the air blowing means 3, and the person in the central part of the room does not directly touch the upward flow of the cold air, so that no discomfort occurs. .

  In this way, the cold air in the lower part of the room rises along the wall 4 provided with the blowing means 3 and the warm air staying below the ceiling 1 falls along the opposing wall 4, so the blowing means 3 is turned on. As a result, the warm air descending air and the cool air ascending air are carried out along the wall 4 so that it is difficult for the person in the room to directly hit the warm air descending air and the cool air rising air, which is effective for the entire room. Convection can be generated in the air, and the temperature difference between the upper part and the lower part of the room can be reduced, and a comfortable room temperature environment can be realized.

  Moreover, since the blowing direction of the wind 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 4 and the temperature difference between the lower part and the upper part of the room more reliably. Can be reduced.

  Here, the operation of the heating unit 2 may be switched from on to off, and at the same time, the air blowing unit 3 may be controlled to be automatically turned on.

  That is, when the heating means 2 is turned on and the radiant heat is emitted from the ceiling 1 into the room to heat the room, the warm air stays near the lower part of the ceiling 1 over time. Then, the operation of the heating means 2 is switched from on to off, and at the same time, the air blowing means 3 is turned on and the warm air staying near the lower portion of the ceiling 1 is lowered along the wall 4. Thereby, while the temperature of the surface of the ceiling 1 and the vicinity of the lower part of the ceiling 1 falls, warm air falls to the lower part of the room, and the lower part of the room can be effectively heated.

  Here, after the air blowing means 3 is turned on, it is controlled to automatically turn off when a set time (for example, several minutes) elapses, and when the air blowing means 3 is switched from on to off, the heating means is again turned on. 2 may be controlled to turn on automatically.

  In this way, the radiation of the radiant heat from the ceiling 1 when the heating means 2 is turned on is radiated into the room → when warm air stays below the ceiling 1, the heating means 2 is switched from on to off and the blower means 3 is turned on and the ceiling 1 Warm air staying in the lower part is sent to the lower part of the room → When a certain time has passed, the air blowing means 3 is switched from on to off and the heating means 2 is switched from off to on to release the radiant heat from the ceiling 1 into the room. Heating operation of resumption can be performed. In the above control, after the air blowing means 3 is turned on, it is automatically turned off when a set time (for example, several minutes) elapses, so that the air is lowered along the wall 4 from above the room. Since only the warm air staying in the lower part of the ceiling 1 is lowered, the incoming air flow is not uncomfortable.

  In the above heating operation, when warm air stays below the ceiling 1, when the heating means 2 is switched from on to off and the blower means 3 is turned on, a temperature sensor is provided in the room, and the temperature sensor provides an upper ceiling in the room. When the temperature of the air below the ceiling 1 is detected and the temperature of the air below the ceiling 1 exceeds a predetermined value, or the temperature sensors provided at the lower and upper parts of the room When the temperature of the air is detected and the temperature difference between the two exceeds a predetermined value, the heating means 2 is automatically switched from on to off, assuming that warm air remains below the ceiling 1. At the same time, the air blowing means 3 may be controlled to be turned on.

  Further, as shown in FIG. 2, a rapid cooling button 7 a may be provided as the operation unit 7 provided in the controller 8. In the embodiment in which the quench button 7a is provided in this way, when the heating means 2 is turned on and the radiant heat is emitted from the ceiling 1 to heat the room, a person in the room feels hot on the face and head. In this case, it may be assumed that warm air stays below the ceiling 1, and the heating unit 2 is switched from on to off by manually operating the rapid cooling button 7a, and the rapid cooling mode in which the blowing unit 3 is turned on may be set. . It is preferable that the operation of the air blowing means 3 in the rapid cooling mode set by manually operating the rapid cooling button 7a automatically stops the rapid cooling mode after a set time (for example, several minutes) has elapsed. In addition, after the rapid cooling mode is automatically stopped again, the heating unit 2 is automatically switched from OFF to ON again by the control unit, and the heating operation of restarting the radiation of the radiant heat from the ceiling 1 into the room is performed. It may be.

  In addition to the rapid cooling button 7a as the operation unit 7, the controller 8 shown in FIG. 2 includes an on button 7b for turning on the heating means 2, an off button 7c for turning off, a menu button 7d, a temperature An up button 7e, a temperature down button 7f, and the like are provided.

  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. It is a front view which shows one Embodiment of the controller used for the same as the above.
