And an active silencer having a microphone, a speaker, and a control board in the air flow path, and an air outlet containing oil and smoke that has passed through the air flow path of the active silencer. It consists of a fan unit equipped with a suction port that flows in and a blower that exhausts air to the outside, and the fan unit is installed behind the ceiling, and the active silencer and the fan unit are connected by a duct. Are those, thereby it is to achieve the intended purpose.

  According to the present invention, a hood unit that is installed above a heating cooker and has a suction port for sucking air containing oily smoke generated during cooking and a discharge port that opens upward, both ends above the hood unit. It has an air passage configured so that four open rectangular cylindrical frames are arranged in parallel to the direction of the opening, and one of the openings at both ends thereof is connected to the discharge port, and the inside of the air passage An active silencer having a microphone, a speaker, and a control board, a discharge port communicating outdoors, a suction port through which air containing oil smoke that has passed through the air passage of the active silencer flows, and air It is composed of a fan unit having a blower that exhausts outdoors, and the fan unit is installed behind the ceiling, and the active silencer and the fan unit are connected by a duct. Knit is installed behind the ceiling, the active silencer and fan unit are connected by a duct, and the cooking device is composed of only the hood unit and active silencer above the heating cooker. The effect that a main body can be installed also in the ceiling height of can be acquired.

The figure which shows the installation state of the range hood of Embodiment 1 of this invention Side sectional view showing a conventional range hood

  A range hood according to claim 1 of the present invention is a hood unit that is installed above a heating cooker and has a suction port for sucking air containing oil smoke generated during cooking, and a discharge port that opens upward. The unit has an air passage configured so that four rectangular cylindrical frames having both ends opened in parallel above the unit are parallel to the direction of the opening, and one of the openings at both ends is connected to the discharge port. And an active silencer having a microphone, a speaker, and a control board in the air passage, and an air containing oily smoke that has passed through the discharge port of the active silencer and the air passage of the active silencer flows in. It is composed of a suction unit and a fan unit having a blower that exhausts air to the outdoors, and the fan unit is installed on the back of the ceiling, and the active silencer and the fan unit are connected by a duct. To. As a result, the fan unit is installed behind the ceiling, the active silencer and the fan unit are connected by a duct, and the heating cooker is composed of only the hood unit and the active silencer. Even if it is incorporated, the main body can be installed at any ceiling height.

  Further, the fan unit may be provided in the back of the ceiling directly above the active silencer. As a result, the duct from the fan unit is connected to the active silencer in the ceiling directly above the vertical, which has almost the shortest length, and the duct resistance can be reduced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
As shown in FIG. 1, a hood unit 1 is installed above a heating cooker 2 that is, for example, a gas stove, and has an inverted bowl-shaped suction port (see FIG. 1) that opens downward to suck in air containing oil smoke 3 generated during cooking. And a discharge port (not shown) that opens upward.

  The air passage 10 has four rectangular frame frames 7 with openings 6 at both ends 5 above the hood unit 1 in the direction of 8 or 9 in the direction of the opening 6. A cylindrical frame 7 configured to be arranged in parallel is provided.

  And the four cylindrical frames 7 are hold | maintained in the inside of the active silencer box 11 with the holding plate 13 provided with the connection port 12 connected to the opening 6 up and down, for example.

  The holding plate 13 is provided inside the active silencer box 11 so that one of the openings 6 at both ends 5 connected to the hood unit 1 is connected to a discharge port (not shown) of the hood unit 1. Moreover, in the ventilation path 10, it has a microphone (not shown), a speaker (not shown), and a control board (not shown).

  The fan unit 14 is provided with a discharge port 16 communicating with the outdoor 15 on the side surface, and a suction port 18 through which air containing oil smoke that has passed through the air passage 10 of the active silencer 17 flows. The fan unit 14 includes a blower 19 composed of a fan that exhausts air to the outdoor 15 and an electric motor.

  The fan unit 14 is installed on the ceiling 20 with, for example, a hanging metal fitting (not shown). The active silencer 17 and the fan unit 14 are connected via a duct 21.

  With this configuration, the fan unit 14 is installed on the ceiling 20, the active silencer 17 and the fan unit 14 are connected by the duct 21, and only the hood unit 1 and the active silencer 17 are disposed above the heating cooker 2. Therefore, even if the active silencer 17 is incorporated, the main body constituted by the hood unit 1 and the active silencer 17 can be installed at any ceiling height in the room.

  The fan unit 14 is provided in the ceiling 20 just above the active silencer 17.

  With this configuration, the duct 21 is connected from the fan unit 14 to the active silencer 17 on the ceiling 20 directly above the upper surface of the active silencer box 11 having the shortest length. The duct resistance due to bending in the duct 21 or the duct length can be reduced.

  The fan unit 14 may be installed in the outdoor 15, and the active silencer 17 and the fan unit 14 may be connected to each other via a duct 21 that communicates with the outdoor 15 through the ceiling 20. With this configuration, the fan unit 14 can be installed at a location that can be easily reached, so that the maintainability of the fan unit 14 can be improved.

  The range hood according to the present invention enables the main body to be installed at the ceiling height of a conventional room even if an active silencer is incorporated. Useful.
