する課題があった。In a conventional range hood like the one above, the air supply passage (2)
The outdoor air discharged from the room to the indoor second outlet (14) forms an air curtain around the indoor air intake (15) of the exhaust passage (3), and the oil smoke and water vapor generated during cooking are removed. This only prevents rust and corrosion of the partition plate (16) by preventing direct contact with the partition plate (16), but when operating in a highly airtight room, the amount of air supply is insufficient and the above oil smoke is generated. It is not possible to collect the air using the supply air, and the operation noise increases, and because the space where the supply air enters is small, the supply air intensively flows in, for example, through the joints of the wall or the gaps between the windows. As a result, there was a problem in that a noise called a whistling phenomenon was generated.
また、冬場において上記隙間よりの給気である隙間風が
人体にとって非常に寒い風となるという課題があった。Additionally, there is a problem in that the draft, which is the air supplied through the gap, becomes extremely cold wind for the human body in winter.
また、上記隙間風により室内外圧力差が大きくなり、室
内のドア等を開閉する場合大きな抵抗力がかかり、開閉
が困難になるという課題があった。In addition, the draft increases the pressure difference between indoor and outdoor spaces, and when opening and closing an indoor door, etc., a large resistance force is applied, making it difficult to open and close.

下部に給気の幕が形成される。In the present invention, an outer casing has an exhaust port and an air supply port in an upper part and an intake port and an air outlet in a lower part, an air supply passage and an exhaust passage that are divided and formed in the outer casing, an air supply blower provided between the air supply port and the discharge port in the air supply passage; an exhaust blower provided between the exhaust port and the intake port in the exhaust passage; and the outer casing. a hood provided at a lower part of the hood; a partition plate protruding from the discharge port toward the front of the hood and disposed to face the inner wall of the hood to form an air passage; and the partition plate. An adjustable air supply branch plate is provided at the tip of the partition plate, and the air supply is arranged along the air path on the partition plate and then discharged to the intake port side and below the hood by the air supply branch plate, The air supply branch plate is connected to an upper piece that contacts the inner wall of the hood at the tip of the partition plate, a connecting piece that extends downward from the upper piece and has a side wall, and a connecting piece that extends from the connecting piece to the discharge port side. Since the central piece is extended and faces the partition plate at a predetermined distance, the air supplied from outside is returned toward the intake port, and this supplied air becomes a guided flow that collects oil smoke. , an air supply curtain is formed at the bottom of the hood.
また、給気分岐板に風穴を穿設したことより、給気流が
風穴を通過しフード下部へ流れる。In addition, since the air supply branch plate is provided with air holes, the air supply flow passes through the air holes and flows to the lower part of the hood.
また、給気分岐板の中央片に先端が中央片中心線上と対
向するよう斜めに配設され、且つ調整可能な複数のルー
バを設けたことより、給気流が吸気口に向って正確に流
れるとともに、その方向が任意に変更できる。In addition, the center piece of the air supply branch plate is arranged diagonally so that the tip faces the center line of the center piece, and has multiple adjustable louvers, allowing the air supply to flow accurately toward the intake port. At the same time, the direction can be changed arbitrarily.
また、給気分岐板内にて風穴と重合される開口を有して

) through the filter (32) and the exhaust casing (
28) and is discharged to the outside from the exhaust duct connection port (36) via a duct (not shown). In this case, about 70% of the oil smoke is collected by the filter (32) and accumulated in the oil sump (32). On the other hand, in the air supply function,
Air supply sirocco fan (39) by air supply motor (38)
rotates. As a result, fresh air from outside is sucked into the air supply casing (37a) through the duct provided at the air supply duct connection port (40), and is separated from the discharge port (24) by the fixed hood partition plate (48). Food storage section (46)
is discharged into the air passage. Furthermore, the air passes along the air path partitioned by the movable hood partition plate (49) in the movable hood part (45), and forms a gap (53) at the air supply branch plate (50) as shown in FIG. Close the air supply port (2) at the louver (73).

) is distributed into a guided flow B (71) in the direction B flowing toward the bottom of the hood (44). Note that the induced flow A
(70) filters oil smoke from the intake port (23) (32)
The induced flow B (71) creates an intake curtain at the bottom of the movable hood part (45), and has the effect of drawing oil smoke that is about to leak from the front of the hood (44) into the hood (44). As shown in FIG. 4(b), the wind direction flows at an inclination of vector A (72) due to the induced flow A <701 and the shape of the lower piece (56) of the supply air branch plate (50). The induced flow B (71) is smaller than the induced flow A (70), and its value is set to about 50% or less of the induced flow A (70). Further, the air supply amount is set to about 20% of the exhaust amount. When the operation is to be stopped, the stop switch (68) of the operation section (63) is turned OFF, the air volume selector switch (65) and the lamp switch (6) are turned off.
7) are turned off at the same time. Next, the main body switch (64)
When the is turned off, the drive unit (57) operates and the movable hood portion 45) is inserted into the hood storage portion (46).
The operation switch (61) is turned OFF, power to the control circuit is turned OFF, and the exhaust air blower (27) and the supply air blower (37) are stopped.

ての寒さがなくなる。As explained above, the present invention includes an outer casing having an exhaust port and an air supply port in the upper part and an air intake port and an air outlet in the lower part, and an air supply passage and an exhaust air partitioned and formed in the outer casing. a passage; an air supply blower provided in the air supply passage between the air supply port and the discharge port; and an exhaust blower provided in the exhaust passage between the exhaust port and the intake port; a hood provided at a lower portion of the outer casing, a partition plate protruding from the discharge port toward the front of the hood and disposed to face an inner wall of the hood to form an air passage; An adjustable air supply branch plate was provided at the tip of this partition plate, and after the supply air was aligned with the air path on the partition plate, it was configured to be discharged to the intake port side and below the hood. 5. The air supply branch plate has an upper piece that contacts the inner wall of the hood at the tip of the partition plate, a connecting piece that extends downward from the upper piece and has a side wall, and a connecting piece that connects the air supply branch plate to the air outlet from the connecting piece. Since it is formed of a central piece that extends toward the exit side and faces the partition plate at a predetermined distance, the simultaneous air supply and exhaust system reduces pressure differences between indoor and outdoor environments and abnormal noise caused by operation. A part of the air supply is discharged to the intake port side, and oil smoke from the cooking device is guided to the intake port, thereby improving the efficiency of collecting oil from the oil smoke. Furthermore, the supply air discharged below the hood is located within the hood, so it does not hit the human body, and there is no draft, eliminating cold in winter.

。Furthermore, by providing the air holes in the air supply branch plate, the air supply flows downward from the air holes, forming an air curtain to prevent oil smoke from leaking from the cooking appliance. Furthermore, the hole diameter of the air hole can be adjusted by drilling, and the flow rate of the air flow in the downward direction can be set to an arbitrary amount, and the optimum guided flow rate can be obtained.

It can be taken into the interior by the induced flow that passes through the hood and flows to the center of the hood, further improving exhaust efficiency.
さらに、ルーバの調整にて角度を変えることにて、左右
にずれて立ち上がる油煙をフード内に取り込むことがで
き、より完全な排気作用ができる。Furthermore, by changing the angle by adjusting the louver, it is possible to capture the oil smoke that rises from the left and right into the hood, allowing for a more complete exhaust effect.

Because of this, the amount of oil smoke can be detected by temperature changes due to cooking conditions,
The flow rate directed toward the bottom of the hood can be automatically adjusted according to the amount of oil smoke, making for more convenient and reliable exhaust action.
