6 to 11, the same components as those in FIGS. 1 to 5 are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 6, the range hood includes a fan unit 4 incorporating a fan (not shown), a frame unit 3 connected to the fan unit 4, a current plate 5 provided below the frame unit 3, And a communication module 57.

  The fan unit 4 includes a fan, a fan casing 54 and an outer shell 55. The fan casing 54 contains a fan. The outer shell 55 covers the fan casing 54.

  The communication module 57 is fixed to the upper surface 3 a of the frame unit 3 by a fixing portion 53. A part of the communication module 57 protrudes into a space 50 separated from the room (for example, a space above the ceiling wall 51).

  As indicated by the air flow A, the air containing the smoke generated during cooking is sucked into the frame unit 3 from the suction portion 12. The air is sucked into the fan casing 54 by the fan. Then, the air is discharged to the outside through a duct 52 connected to the fan casing 54.

  Here, a part of the fixing portion 53 may be provided in a region exposed to the air flow A.

  FIG. 7 is a top view of the range hood as viewed from above to below. Although not shown in FIG. 6, the flange portion 3 b of the frame unit 3 is also shown in FIG. 7.

  FIG. 8 is a bottom view of the range hood as viewed from below to above. Although not shown in FIG. 6, the lead wire 61 connected to the communication module 57 is also shown in FIG. 8. In addition, FIG. 8 is a figure of the state which removed the baffle plate 5. As shown in FIG.

  Thus, in the range hood of the present embodiment, the transmission / reception unit case 58 is provided on the upper surface 3 a of the frame unit 3 so that the transmission / reception unit 59 protrudes into the space 50 separated from the room 1.

  According to this structure, it can suppress that the air containing oil smoke contacts the transmission / reception part 59. FIG. As a result, failure of the communication module 57 can be suppressed, and deterioration of the reception sensitivity of the communication module 57 can be suppressed.

  In addition, although the transmission / reception part 59 is covered with the transmission / reception part case 58, when there is a gap in the transmission / reception part case 58, air may enter the transmission / reception part case 58 from the gap. Unlike the present embodiment, if the transmission / reception unit 59 protrudes into a space directly connected to the room 1 (for example, the space below the upper surface 3a), air containing oily smoke is transmitted / received through the gap of the transmission / reception unit case 58. There is a risk of flowing into the periphery of the portion 59. At this time, the transmission / reception unit may be contaminated by the air and the communication module may break down, or the heat of the air may adversely affect the reception sensitivity of the communication module.

  On the other hand, in the range hood of this embodiment, even if there is a gap in the transmission / reception unit case 58, the transmission / reception unit 59 protrudes into the space 50 (the transmission / reception unit 59 is above the upper surface 3a). It can suppress that the contained air contacts the transmission / reception part 59. FIG. In particular, the fixing portion 53 provided below the upper surface 3a further suppresses the inflow of contaminated air into the transmitting / receiving unit case 58. As a result, the failure of the communication module 57 can be further suppressed, and the deterioration of the reception sensitivity of the communication module 57 can be further suppressed.

  Further, by causing the transmission / reception unit 59 to protrude into the space 50, the transmission / reception unit 59 can be brought out of the main body 2.

  Thus, the transmission / reception unit 59 can transmit and receive radio waves via the transmission / reception unit case 58. Even when the transmission / reception unit 59 of the communication module 57 is provided in the main body 2, the radio wave propagation to the transmission / reception unit 59 is achieved. The strength reduction can be suppressed.

  And with the range hood of this embodiment, the communication module 57 can be mounted on the range hood while suppressing an increase in construction man-hours.

  And even if it is a case where the communication module 57 is mounted in the main body 2, the range hood which can suppress the intensity | strength fall of the electromagnetic wave propagation to the transmission / reception part 59 while reducing the influence of the oil smoke during cooking can be provided.

  As in FIG. 3, the communication module 57 performs wireless communication with the central control device 31 that controls the other ventilation devices 32 b, 32 c, and 32 d via radio waves via the transmission / reception unit 59.

  The communication module 57 of FIG. 11 is the same as that of FIG.

  The transmission / reception unit case 58 is provided on the upper surface 3 a of the frame unit 3 so that the transmission / reception unit 59 protrudes into an internal space 80 that is a space 50 separated from the room 1.

  According to this structure, it can suppress that the air containing oil smoke contacts the transmission / reception part 59. FIG. As a result, failure of the communication module 57 can be suppressed, and deterioration of the reception sensitivity of the communication module 57 can be suppressed.

  Further, by projecting the transmission / reception unit 59 in the internal space 80, the transmission / reception unit 59 can be taken out of the main body 2, so that the transmission / reception unit 59 can transmit and receive radio waves via the transmission / reception unit case 58. Become.
