It can be located on the lower side. As a result, the lower bracket 17a can prevent air from flowing into the first slit 10SL without passing through the first heater 17.

The second heater 27 (see FIG. 4) may be left and right symmetrical to the first heater 17. The contents described above and below regarding the first heater 17 may be equally applied to the second heater 27.

Referring to FIGS. 7 and 8, the first heater 17 may be a sheath heater. The first heater 17 may include terminals 171, a tube 172, and a plurality of fins 173.

For example, the number of pins belonging to the third section P13 may be 3 to 6. The second section (P12) may be the remaining section excluding the first section (P11) and the third section (P13). For example, the number of pins belonging to the second section P12 may be greater than the number of pins belonging to the first section P11 and the second section P12.

In this case, the gap between the pins in the first section (P11) and the third section (P13) may be smaller than the gap between the pins in the second section (P12). For example, the spacing between pins belonging to the first section P11 and the third section P13 may be 3.1 mm, and the spacing between pins belonging to the second section P12 may be 6.2 mm.

Accordingly, when current flows through the terminals 171 to the heating wire, the first heater 17 can heat the air passing through the first heater 17. Additionally, air rising in the first flow path 10P may flow between the plurality of fins 173 of the first heater 17.

Each of the first vane 174a, the second vane 174b, the third vane 174c, and the fourth vane 174d may be provided in plural numbers.

Additionally, the first vane 174a and the second vane 174b may be spaced further apart from the first slit 10SL than the third vane 174c and the fourth vane 174d. In other words, in the flow of air passing through the first heater 17 and the first slit 10SL, the first vane 174a and the second vane 174b are connected to the third vane 174c and the fourth vane 174d. ) can be located upstream of.

It may be inclined in a second direction. The first direction may intersect the second direction. The first direction and the second direction may intersect each other on the upper side of the pin 173, and the angle between the first direction and the second direction may be an acute angle. In other words, the first direction may be a direction inclined from the longitudinal direction of the first part 172a toward the longitudinal axis of the first heater 17, and the second direction may be a direction inclined toward the longitudinal axis of the first part 172c. The direction may be inclined towards the longitudinal axis of the first heater 17. For example, the first direction and the second direction may be symmetrical to each other with respect to the longitudinal axis of the first heater 17.

Accordingly, air can flow up and down the fins 173 by the slot 173S and the vane 174 and pass between the plurality of fins 173. That is, the air may flow obliquely upward from the bottom of the fin 173 and pass around the first part 172a, and may flow obliquely downward from the top of the fin 173 and pass around the third part 172c. can do. Due to this flow of air, the heat exchange time between the first heater 17 and the air is increased (i.e., the residence time of the air is increased), thereby improving heat transfer performance and preventing overheating of the first heater 17. You can. Additionally, the vane 174 can smoothly guide the air that has passed through the first heater 17 to the first slit 10SL.

For another example, the fins 173 of one section P21 are louver fins having the slot 173S and the vane 174 described above with reference to FIGS. 9 and 10 and are spaced apart from each other at a first interval. Although spaced apart, the fins 173 of the other section P22 are plate fins that do not have the slot 173S and the vane 174 described above with reference to FIG. 8 and may be spaced apart from each other at a second interval. . The first interval may be larger than the second interval. As a result, sufficient space (passage) between the pins 173 in one section P21 can be secured.
