Description

  The present invention relates to a radiant heating apparatus including an elongated heater for radiating radiant heat, and in particular, a radiant type that can disperse the fan wind over the entire length of the heater without using a cross flow fan. It relates to a heating device.

  DESCRIPTION OF RELATED ART Conventionally, the heating apparatus for bathrooms provided with the warm air supply unit for supplying warm air in a bathroom, and the thermal radiation unit for radiating radiant heat in a bathroom are known. An example of this type of bathroom heating device is described in, for example, JP-A-2002-333153.

  In the bathroom heating device described in JP-A-2002-333153, by supplying warm air into the bathroom, for example, a warm air supply unit (main body side unit) for heating the bathroom in advance before bathing. Is provided. Specifically, the hot air supply unit (unit side unit) is provided with a ceramic heater for heating the air supplied into the bathroom and a fan for supplying the heated air into the bathroom. Yes.

  When hot air is supplied into the bathroom by the hot air supply unit (main unit) while the user is taking a bath, the user's body may be deprived of heat of evaporation and the user may feel cold In view of the above, in the bathroom heating device described in Japanese Patent Application Laid-Open No. 2002-333153, a heat radiation unit (heater unit) for radiating radiant heat into the bathroom separately from the hot air supply unit (main body side unit). Is provided. That is, during the user's bathing, the heat radiation unit (heater unit) is mainly used rather than the hot air supply unit (main body side unit). Specifically, the heat radiation unit (heater unit) is provided with a carbon lamp heater for radiating radiant heat into the bathroom.

JP 2002-333153 A

  However, in the bathroom heating device described in JP-A-2002-333153, as described above, a heat radiation unit (heater unit) is provided so that the user does not feel cold during bathing. A heat radiation unit (heater unit) is arranged together with a hot air supply unit (main body side unit) on a ceiling relatively far from the user who is taking a bath. Therefore, in the bathroom heating device described in JP-A-2002-333153, the radiant heating effect by the radiant heat radiated from the heat radiating unit (heater unit) may be weakened before reaching the user. That is, the user may still feel cold during bathing.

  Moreover, in the heat radiation unit (heater unit) described in Japanese Patent Application Laid-Open No. 2002-333153, an elongated carbon lamp heater is used as a carbon lamp heater for radiating radiant heat into the bathroom. That is, in the heat radiation unit (heater unit) described in JP-A-2002-333153, an elongated carbon lamp heater having a relatively large longitudinal dimension is used to radiate radiant heat over a wide area in the bathroom. Yes.

  By the way, if the heater that radiates radiant heat rises excessively, the device body itself becomes hot, and it is necessary to avoid the danger of touching the device body with your hand. Therefore, the radiant heating apparatus having a heater that radiates radiant heat has conventionally been provided with a fan for cooling the heater.

  However, as described above, when an elongated heater having a relatively large longitudinal dimension is used, the entire longitudinal direction of the elongated heater cannot be cooled by a fan such as a sirocco fan. Specifically, for example, when a sirocco fan is disposed in the center of the elongated heater, the end of the elongated heater is not sufficiently cooled. Therefore, conventionally, when an elongated heater having a relatively large longitudinal dimension is used, a cross flow fan has to be used to cool the entire longitudinal direction of the elongated heater. Since the crossflow fan is more expensive than other fans, when the crossflow fan is used, the cost of the entire apparatus increases accordingly.

  In view of the above problems, an object of the present invention is to provide a radiant heating device that can disperse the wind of a fan over the entire longitudinal direction of a heater without using a cross flow fan.

  According to the first aspect of the present invention, in the radiant heating apparatus having an elongated heater for radiating radiant heat, a fan for cooling the heater is provided, and the wind sent from the fan is distributed in the entire longitudinal direction of the heater. The dispersion member is provided separately from the fan, and the dispersion member is a tubular member extending substantially parallel to the longitudinal direction of the heater, and an opening is formed in the peripheral surface of the dispersion member. A radiant heating device is provided, in which a guard member for protecting the heater is disposed substantially parallel to the heater, and an opening is formed in a portion of the peripheral surface of the dispersion member facing the guard member. The

  In the radiant heating device according to claim 1, an elongated heater for radiating radiant heat and a fan for cooling the heater are provided, and further the wind of the fan is distributed over the entire longitudinal direction of the elongated heater. Dispersing members for this purpose are provided separately from the fan. Specifically, the dispersion member is constituted by a tubular member extending substantially parallel to the longitudinal direction of the heater, and an opening is formed on the peripheral surface of the dispersion member. Therefore, without using a cross flow fan, the wind of a fan such as a sirocco fan can be dispersed throughout the longitudinal direction of the heater by the dispersing member. That is, the cost of the entire radiant heating device can be reduced as compared with the case where an expensive crossflow fan is used.

  In the radiant heating device according to the first aspect, the guard member for protecting the heater is arranged substantially in parallel with the heater. Further, an opening is formed in a portion of the peripheral surface of the dispersion member that faces the guard member. Specifically, the fan wind is first moved through the dispersion member substantially parallel to the longitudinal direction of the guard member, and then through the opening in a direction substantially perpendicular to the longitudinal direction of the guard member. The guard member is cooled by the wind. Therefore, the guard member can be cooled over the entire longitudinal direction of the guard member without using a cross flow fan.

In view of the fact that the temperature of 53 is easier to heat up, and accordingly, the central portion 53 is more likely to heat than the end portions 51 and 52 of the reflector 24 and the guard member 25. The amount of wind blown from the opening (not shown) formed in 53 is larger than the amount of wind blown from the opening (not shown) formed in the end portions 51 and 52 of the tubular member 23. Thus, the dimension of the opening is set. Therefore, for example, when the amount of wind blown from the opening formed in the central portion 53 of the tubular member 23 is smaller than the amount of wind blown from the openings formed in the end portions 51 and 52 of the tubular member 23. Or, the amount of wind blown from the opening formed in the central portion 53 of the tubular member 23 is equal to the amount of wind blown from the openings formed in the end portions 51 and 52 of the tubular member 23. In addition, it is possible to avoid that the temperature of the central portion 53 of the heater 21, the reflecting plate 24, or the guard member 25 becomes higher than the temperatures of the end portions 51 and 52.
