Description

  The present invention relates to a protective guard for a heater, and more particularly to a protective guard for a heater that is attached to a hot air outlet of a hot air blowing type heater such as a fan heater and prevents burns and the like.

  The hot air blowing type heater using oil or gas is mainly a portable type that burns indoor air, and has a sufficient capacity to warm the room while being compact. For this reason, in the heater, the heat source portion in use is considerably hot, and the metal fittings that are the louvers of the hot air outlet are also hot. Therefore, if an infant or the like accidentally touches the louver, there is a risk of burns.

  Therefore, in recent years, as a means for solving this problem, a means has been proposed in which a protective guard for a heater is attached to the warm air outlet of the heater so as to prevent direct contact with the louver of the hot air outlet. (For example, refer to Patent Document 1).

  As shown in FIG. 7, the protection guard 60 for a heater disclosed in Patent Document 1 covers the louver on the front surface of the hot air outlet 52 in which a hot hot zone of the heater 51 is formed. The guard attachment unit 70 fixedly attached to the frame body 53 of the 50 and the guard unit 80 attached to cover the front surface of the louver at the hot air outlet 52 through the guard attachment unit 70.

  More specifically, the guard mounting unit 70 is formed of a metal rod, and side guard portions 70b, 70c, 70d in the form of vertical grids covering the upper, lower, left and right sides in front of the hot air outlet 52, respectively. 70e and a vertical lattice-shaped front guard part 70a that covers the front face of the hot air outlet 52 and is connected to each of the side guard parts 70b to 70e, and has a substantially trapezoidal cross section. ing.

  On the other hand, the guard unit 80 is formed by forming a metal bar whose outer periphery is covered with a silicon rubber tube having a low thermal conductivity in the form of an equidistant vertical lattice and fixed to the front surface of the front guard portion 70a. ing.
