In addition, about the same structure as 1st embodiment, description is abbreviate | omitted by attaching | subjecting the same code | symbol.

  An indoor circulating air purification device (hereinafter referred to as “purification device”) AA is adjacent to a cabinet B provided with an electromagnetic induction heating cooker (hereinafter referred to as “heating cooker”) C, and a floor F such as a kitchen. It is installed on the top. A person who cooks using the cooking pan D placed on the heating cooker C stands on the floor F, particularly on the floor F around F1, and cooks. Accordingly, the purifier AA is installed on the opposite side of the cooker B from the cooker, that is, on the far side of the cabinet B as seen from the cooker.

  Further, the purification device AA includes a wall portion 2'A that rises above the upper surface (counter B3) of the cabinet B and is provided on the rear box portion B2A. The wall 2′A is provided with a blowout port 6A on the opposite side of the suction port 1A and the suction port 1A, with the suction port 1A facing toward the cabinet B and the blower port 6A facing away from the cabinet B. The As a result, the wall 2′A is installed so that the suction port 1A is directed toward the heating cooker C, and the wall 2′A is located behind the heating cooker C on the cabinet B when viewed from the cook. The suction port 1A is provided so as to be directed to the heating cooker C.

  By providing the suction port 1A so as to be directed to the heating cooker C, the suction port 1A can suck in the polluted air G containing smoke, fats and oils, odors, etc. generated by cooking with the heating cooker C. It becomes.

  Further, the air outlet 6A is provided in the wall 2'A so that the air g blown from the air outlet 6A does not face the cooking device C side. Typically, as in the present embodiment, the outlet 6A is provided on the wall 2'A on the side opposite to the inlet 1A, that is, on the back side. However, since the air flow of the contaminated air G generated from the cooking pan D or the like is not disturbed unless the air g blown from the outlet 6A is directed to the cooking device C, the present invention is not limited to this. 6A may be on the side surface of the wall 2'A. In the present embodiment, unlike the first embodiment, the outlet 6A is not provided in the back plate bA of the back box portion B2A. The direction facing F1 where the cook stands is the front, the back is the surface opposite to the front, and the side is the surface between the front and the back, which is roughly perpendicular to the floor. To tell.

  Thereby, air currents, such as contaminated air G which generate | occur | produces from the cooking pan D on the heating cooker C, are not disturb | confused by the airflow of the purified air which blows back into the room | chamber interior from the blower outlet 6A. Further, unlike the prior art, the outlet 6A is not provided on the upper surface (counter B3) of the cabinet B or the wall top surface T of the wall portion, so that there is no possibility that dust or the like enters and the dishes necessary for cooking And seasonings can be placed, and the upper surface (counter B3) of the cabinet B and the top surface T of the wall can be effectively used as a space for placing objects.

  The height of the suction port 1A in the wall 2'A from the upper surface (counter B3) of the cabinet B is preferably provided at a position slightly higher than the height of the cooking pan D placed on the heating cooker C. Since the contaminated air G rises upward from the cooking pan D, the suction port 1A easily sucks the contaminated air G. Further, the width of the suction port 1A is preferably slightly wider than the width of the heating cooker C. 1 A of suction inlets are easy to inhale the polluted air G which stands up while spreading upward from the cooking pan D.

  In the present embodiment, the height of the air outlet 6A in the wall 2'A is provided at substantially the same height as the air inlet 1A (height from the floor surface F). However, the present invention is not limited to this, and it may be close to the upper surface (counter B3) of the cabinet B and may be at a lower position in the wall 2'A. The width of the outlet 6A is substantially the same as the inlet 1A in this embodiment. However, it is not limited to this.

  Although the opening part of 1 A of suction inlets and 6 A of blowing outlets is a rectangle, it is not limited to this. The opening areas of the openings of the suction port 1A and the outlet 6A are appropriately determined based on the blowing capacity of the blower 4, but the opening areas of both the openings are substantially the same, or the opening area of the opening of the outlet 6A is better. Somewhat large is preferable. Since air is not blown out from the blowout port 6A at a speed higher than the suction speed of the suction port 1A, the airflow of this air disturbs the airflow of the contaminated air G generated from the cooking pan D on the heating cooker C. There is nothing.

  The blowing direction of the air from the blowing outlet 6A is a direction in which the airflow of the contaminated air G generated from the cooking pan D on the heating cooker C is not disturbed. Preferably, even if it hits a shelf, furniture, ceiling, etc. located above or opposite to the outlet 6A, it does not flow backward toward the cooking device C, specifically 45 degrees above the horizontal direction. The direction is lower than the direction facing the.

  More preferably, it is a substantially horizontal direction or a downward direction from the substantially horizontal direction. Thereby, the airflow of the contaminated air G generated from the cooking pan D on the heating cooker C and the like is not disturbed by the airflow of the purified air blown back into the room from the outlet 6A. If the blowing direction is obliquely downward, the blown air does not hit a person on the dining side across the cabinet B, and there is no unpleasant feeling.

  The air blowing direction at the air outlet 6A is typically adjusted by a horizontal louver shown in FIG. 9 provided at the air outlet 6A. However, the present invention is not limited to this, and the outlet 6A itself may be provided so as to be rotatable in the vertical direction.

  Further, the purification device AA has an air passage 3′A that connects the suction port 1A and the outlet 6A, and the outlet 6A discharges air sucked from the inlet 2′A through the air passage 3′A. To do. The purification device AA is on the air passage 3′A and generates a flow of air from the suction port 1A to the air outlet 6A, and the contaminated air that is on the air passage 3′A and is sucked from the air inlet 1A. An air purifying unit 5 is provided for purifying the air. In this embodiment, although the air blower 4 exists in the upstream of the air purification | cleaning part 5, it is not limited to this, The air blower 4 and the air purification | cleaning part 5 may exist in an upstream.

(Downward). The air purification unit 5 is provided immediately above the blower 4. Therefore, the contaminated air G sucked from the suction port 1A by the negative pressure generated by the blower 4 flows downward along the air passage 3′A, passes through the blower 4, and is then purified by the air purifying unit 5. The Thereafter, the purified air flows upward along the air passage 3'A communicating with the blowout port 6A due to the positive pressure of the blower 4, and is discharged from the blowout port 6A to the outside of the purification device AA.

  The width when viewed from the front or back side of the air passage 3'A is not particularly limited, at least in the vicinity of the inlet 1A and the outlet 6A, except that it is substantially the same as the width of the inlet 1A and the outlet 6A. They may all be formed with the same width, or may be narrowed to substantially the same width as the blower 4 in the portion near the blower 4 of the air passage 3'A through which the polluted air G flows downward. Further, in the air passage 3′A through which air flows upward, the air purification section 5 may have the same width as the outlet 6A, and the air passage 3′A may have the same constant width as the outlet 6A. 5 may have the same width as the blower 4, and the air passage 3 ′ A may have the same width as the air purification unit 5, and may have a shape that widens toward the outlet 6 </ b> A. In addition, the width | variety at the time of seeing from the side surface of air path 3'A is formed in fixed width | variety except the air blower 4 and the air purification | cleaning part 5.
