Description of the Related Art Among heaters, those which circulate warm water or the like heated by an outdoor combustion section through a radiator provided in a room to warm the room have recently been used because they do not pollute the air in the room. Used. Since such a heater cannot visually recognize a flame like a heater having a combustion part in a room, conventionally, in order to give warmth not only by heating with warm air but also visually, Attempts have been made to create a flame.

[0003] For example, the applicant of the present application, Kaikaihei 6-73
As disclosed in Japanese Patent Application Laid-Open No. 605, a pseudo flame is produced by irradiating a translucent pseudo-wood with light from a lamp through a translucent rotating body to give a visual warmth. .

However, in the above-mentioned invention, since the rotating body is formed by changing the thickness of a transparent acrylic resin or the like, or by changing the degree of shading by coloring, a remarkable fluctuation is given to light. Was difficult. Further, the rotation speed of the rotating body is changed in conjunction with the temperature controller, but if the temperature is the same, the rotation is constant, so that the fluctuation is monotonous.

[0005]

SUMMARY OF THE INVENTION The present invention is to further improve the performance of the above-mentioned simulated flame, and makes it possible for a heater to make a user feel as if burning materials such as firewood are burning. The purpose is to give a visual warmth to the.

In order to achieve the above object, a simulated combustion expressing device in a heater according to the present invention comprises a light source and a rotating body having a slit and a reflecting surface on a surface facing the light source. And a reflector that reflects light from the light source through a reflecting surface of a rotating body, wherein the light from the light source passes through the slit and the simulated combustion. In addition to being applied to the inside of the object, the light reflected by the reflecting surface is applied to the inside of the pseudo-combustion object by the reflector, bypassing the rotating body.

According to this, the light from the light source is blocked by the rotating body, and the light passing through the slit of the rotating body is radiated to the inside of the pseudo combustion material. In addition, the rotation of the rotating body causes fluctuations in the light applied to the inside of the pseudo combustion product.
In addition, not only the light passing through the slit, but also the light reflected by the reflecting surface of the rotating body and the light reflected by the reflecting plate is circulated around the rotating body and is applied to the inside of the pseudo-combustion material. A complex fluctuation occurs in the light irradiated to the light. Since the pseudo-combustion material has a light-transmitting property, when the light applied to the inside of the pseudo-combustion material appears on the surface of the pseudo-combustion material, the fluctuation of the light produces an effect as if the pseudo-combustion material is burning. The user of the vessel can be visually warmed. In addition, by providing the simulated combustion expression device of the present invention in a heater, it is possible to add a sense of quality to the product.

[0008] Further, by providing a light-transmitting filter for coloring light from the light source in different shades between the light source and the inner surface of the pseudo-combustion product, the light applied to the inside of the pseudo-combustion product is warmed. And the fluctuation of the illuminating light can be made more complicated.

The rotator may be rotated by convection due to heat generated by the light source, or may be rotated irregularly by a motor. When the rotating body is rotated by convection, no separate power is required to rotate the rotating body, so that the apparatus can be simplified and the cost can be reduced. When the rotating body is rotated by the motor, the rotating body can be rotated irregularly, so that more complex fluctuations can be given to the light applied to the pseudo combustion material.

When the hot water is not warm as in the beginning of operation, heating is performed by blowing warm air from the electric heater 9 through the front opening of the main body 4.

The simulated combustion expressing device 1 performs simulated combustion expression by irradiating light from a light source 11 to a simulated firewood 3, and as shown in FIGS. 1 to 3, from the opening of the heater 2. The firewood 3 is provided so that it can be visually recognized, and a box-shaped case 12 that partitions the lower part of the firewood 3 is provided. A light source 11 and a rotating body 13 are housed inside the case 12, and a filter 14 is provided on one side between the light source 11 and the pseudo wood 3.
