Usually, a low-pressure mercury lamp is used as a germicidal lamp. As shown in Figure 5, this low-pressure mercury lamp emits the most 253.7 nm ultraviolet light (sterilizing radiation), which has excellent sterilizing power, when the ambient temperature is around 20°C. However, as the ambient temperature rises, the mercury vapor pressure inside the germicidal lamp increases and the luminous efficiency decreases.As a result, as shown in Figure 5, the amount of 253.7nm ultraviolet rays (sterilizing radiation) generated decreases, and when the temperature reaches around 80℃, The amount of germicidal radiation generated was close to zero. For this reason, when a normal sterilizing lamp is placed in a hot air duct, the sterilizing effect is poor, and sterilizing in hot air at around 80°C is especially impossible.

In the sterilizing device of the present invention, a sterilizing lamp 2 is arranged in a hot air path 1 parallel to the flow direction of the hot air, and a sterilizing lamp 2 is placed in a concave portion 7 that projects toward the inside of the hot air path 1 and opens to the outside. It is characterized by exposing both ends of the lamp 2, and by adopting such a configuration, the above-mentioned object of the present invention is achieved.
That is, in the present invention, by positioning a part of the germicidal lamp 2 outside the hot air passage 1, even if the temperature inside the hot air passage 1 is high, sterilization can be carried out by cooling a part of the germicidal lamp 2. Reduces the mercury vapor pressure inside the lamp 2 and has excellent sterilizing power.
The amount of 253.7nm ultraviolet rays generated hardly decreases, making it possible to sterilize in hot air.In addition, the germicidal lamp 2 is placed parallel to the flow direction of the hot air in the hot air path 1. This makes it possible to increase the irradiation dose (time) per unit of hot air and improve the sterilization effect. Since both ends 2a of the germicidal lamp 2 are exposed in the recess 7 that opens to 2a to the outside, insert the end 2 of the germicidal lamp 2 into the recess 7 of the hot air path 1.
By positioning a, the end 2a of the germicidal lamp 2 can be protected, and a cover or the like to protect the end 2a of the germicidal lamp 2 that protrudes to the outside is provided so as to protrude greatly from the outside of the hot air path 1. It's not necessary. The present invention will be explained in detail below with reference to Examples. Warm air path 1
A germicidal lamp 2 is placed inside, but this germicidal lamp 2
A part of the hot air passage 1 is located outside the hot air path 1 (that is, on the room temperature side). That is, as shown in FIG.
Germicidal lamps 2 are arranged in parallel to the hot air flow direction (direction of arrow A in FIG. The sterilizing lamp 2 is located in a protruding recess 7 that is open to the outside, and is cooled by the outside air at both end portions exposed to the outside. Then, the germicidal lamp 2 is turned on to sterilize the hot air (for example, about 80°C) flowing through the hot air path 1, and in this case, even if the atmospheric temperature inside the hot air path 1 is about 80°C. , a part of the germicidal lamp 2 is located outside the hot air path 1 and is cooled, thereby lowering the mercury vapor pressure inside the germicidal lamp 2,
The amount of 253.7 nm ultraviolet rays (sterilizing radiation) generated does not decrease and is almost the same as that of germicidal radiation in a low-temperature atmosphere, and the sterilizing effect in a high-temperature atmosphere is not reduced. FIG. 2 is a graph showing the relationship between the ambient temperature (inside duct temperature) and the amount of 253.7 nm ultraviolet light (sterilizing radiation) when both ends 2a of the germicidal lamp 2 are exposed to the room temperature side in the present invention. In Although,
As is clear from this graph, the sterilization dose hardly decreases even if the ambient temperature rises (for example, 80°C). In the present invention, since the sterilizing lamp 2 is arranged in the hot air path 1 in parallel to the flow direction of the hot air, the irradiation dose (time) per unit hot air is large, so the sterilizing effect is This will improve the results. FIGS. 3 and 4 show an example in which the sterilizing device of the present invention is used in a futon drying device. The futon drying device shown in FIGS. 3 and 4 has a futon mounting table 9 provided inside the futon drying chamber 8.
A hot air outlet 10 is provided in the center of the futon table 9. The futon dryer 8 is further provided with a hot air path 1, and one end of the hot air path 1 is connected to the hot air outlet 1.
0, and the other end of hot air path 1 is return port 1.
1. A fan 12, a heater 13, and a germicidal lamp 2 are installed inside the hot air path 1. Here, in FIG. 3, a part of the sterilizing lamp 2 is not shown outside, but a part of the sterilizing lamp 2 is placed outside the hot air path 1 as shown in FIG. 1, for example. It's out.
In the figure, reference numeral 14 denotes a shutter-like door, which is attached to the opening of the futon dryer 8 so that it can be opened and closed. Reference numeral 15 denotes an exhaust pipe, which exhausts a portion of the hot air passing through the hot air path 1 to prevent moisture and odor from being trapped. Then, with the futon 16 placed on the futon placing table 9, hot air is blown from the hot air outlet 10 to the center of the lower surface of the futon 16, and is passed through the inside of the futon 16 to dry the futon 16. Furthermore, return port 11
The hot air is sucked in and sent to the fan 12 again, sterilized with a germicidal lamp 2, heated with a heater 13, and hot air is again blown out from the hot air outlet 10 to the center of the lower surface of the futon 16. In this way, warm air is circulated to dry the futon 16 without heat loss. In this case, when hot air is circulated and used, the temperature of the circulating hot air reaches about 80°C in the germicidal lamp 2 part in the hot air path 1. However, in the present invention, a part of the germicidal lamp 2 The germicidal lamp 2 is located not only in the air path 1 but also outside the futon drying chamber 8), and by locating a part of the germicidal lamp 2 outside in this way, the atmospheric temperature in the hot air path 1 becomes approximately 80°C. However, the mercury vapor pressure inside the germicidal lamp 2 can be lowered, the amount of germicidal radiation generated can be prevented from decreasing, and the germicidal effect does not deteriorate. Therefore, by adopting a circulation method as shown in Fig. 3 in which hot air is circulated in the futon drying chamber 8, the sterilization effect does not decrease even if the temperature inside the hot air path 1 becomes high. Compared to futon dryers, it is energy efficient because it circulates hot air. In the above embodiment, the sterilizing device of the present invention is used in a futon dryer, but it may also be used in a clothes dryer, a shoe dryer, a dish dryer, etc.

In the present invention, as described above, a sterilizing lamp is arranged in a hot air path parallel to the flow direction of hot air, and a sterilizing lamp is placed in a recess that is opened to the outside and protrudes toward the inside of this hot air path. Both ends of the lamp are exposed, so even if the atmospheric temperature in the hot air duct rises, a part of the germicidal lamp is cooled down and the mercury vapor pressure is lowered, so the amount of germicidal radiation does not decrease and the hot air It can be sterilized in the same way as at room temperature, and by arranging the sterilizing lamps parallel to the flow direction of the hot air in the hot air duct, the irradiation dose (time) per unit of hot air can be greatly increased. In addition, both ends of the germicidal lamp are exposed in a recessed area that protrudes into the hot air duct and opens to the outside. The germicidal lamp can be cooled from both ends for effective cooling, and when the end is exposed to the outside to cool the germicidal lamp, sterilization can be achieved by positioning the end of the germicidal lamp in the recessed part of the hot air path. The end portion of the lamp can be protected, and there is no need to provide a cover or the like to protect the end portion of the germicidal lamp that protrudes to the outside of the hot air path.
