Description

[Detailed description of the invention] [Industrial application field] This invention relates to a ventilation fan that exhausts smoke, steam, exhaust gas, etc. generated during cooking in a kitchen range to the outside.

[Prior Art] Conventionally, this type of ventilation fan has generally had a suction port located almost directly above the microwave oven, and has a mechanism for sucking rising air from the microwave oven and discharging it outdoors. However, since the above-mentioned ventilation fan has an inlet at a predetermined height from the range, oily smoke rising from the range tends to spread from the middle, and a large-capacity blower is required to exhaust such oily smoke. Replacing and cleaning the filter used in the ventilation fan is extremely difficult because the ventilation fan is located above the user.

There is also a cooking exhaust device as shown in, for example, Japanese Patent Application Laid-open No. 131949/1983, which has a suction port at the rear of the cooking table as shown in FIG. This cooking exhaust system has a rising part 103 formed at the rear of a cooking table 101 on which a gas range 102 is arranged or disposed, and an air intake port 104 on the upper surface of this rising part 103 on the side of the range 102. A forward airflow guiding plate 105 is provided above the range 102 on a wall that is inclined towards the front and stands upright in contact with the rear part of the rising part 103. A duct 106 is connected to the intake port 104, and a blower 108 is provided at the exhaust port 107 at the end of the duct 106 to form an exhaust path. More and more waste is being discharged outdoors. In addition, 109 and 110 in the figure are airflow guide grids,
111 is a sky fire installed at the bottom of the range 102, 11
2 is the sky forced smoke pipe, 113 is this sky fire forced smoke pipe 1
12 openings.

[Problems to be solved by the invention] The conventional cooking exhaust device as described above sucks oily smoke etc. generated during cooking without dispersing upward. Since it is formed on the back side, the cooking table 101 must be moved forward to make room for the exhaust passage, and the space on the front wall above the cooking table 101 cannot be used effectively. Also,
Since the exhaust flow is downward, a large blower is required for sufficient exhaustion.

This invention was made to solve this problem, and it is possible to suck up oil smoke etc. generated during cooking upwards without spreading it out and efficiently discharge it outdoors. The purpose is to obtain a ventilation fan that can be used as a shelf for placing containers.

[Means for Solving the Problems] The ventilation fan of this invention includes an air supply fan that sucks outside air above the oven, a discharge port that blows outside air downward, and an air blowing mechanism that has an exhaust fan and a suction section, respectively. A duct is connected to the suction part, which has an intake port that sucks in oil smoke, etc. from the range, at a position close to the range, and the upper part of the intake port bends the outside air blown downward from the discharge port to collect oil smoke, etc. In addition to suppressing upward diffusion, the eaves are provided with a recessed portion for placing a seasoning container or the like on the upper surface.

[Function] According to this invention, the outside air blown downward from the discharge port by the air supply fan collides with the canopy attached to the duct and curves, and this outside air envelops oil smoke etc. generated during cooking and spreads upward. By suppressing this, the above-mentioned oil smoke, etc. can be sucked in through the duct's intake port and discharged outdoors without spreading, and the eaves can be effectively used as a shelf to stably place seasoning containers, etc. can be used.

[Embodiment of the invention] A ventilation fan as an embodiment of the invention shown in FIGS. 1 to 3 includes an air supply fan 3 that is installed above a range 1 in a kitchen and sucks outside air through a duct 2; It has a structure in which a suction duct 6 is extended along the wall surface of the kitchen in a drooping manner to the vicinity of the range 1 in the ventilation mechanism section 5 incorporating an exhaust fan 4 that sucks air through the duct 2 and exhausts the air to the outside. . The air blowing mechanism section 5 is formed in a box shape, and has an air supply fan 3 and an exhaust fan 4 built in side by side inside, and a suction section 7 communicating with the suction side of the exhaust fan 4 on the bottom surface, and an air supply fan 3 on the bottom surface. Two discharge ports 8 and 9 communicating with the discharge side of the fan 3 are open. One end of a suction duct 6 in the shape of a flat rectangular cylinder is connected to the suction part 7, and the outside air blown out from one of the discharge ports 8 and 9, which opens downward in front of the suction part 7, is The water flows downward along the front surface of the suction duct 6. Another outlet 9
is configured to blow outside air diagonally forward and downward, and is normally adjusted so that the outside air is directed toward the face of a cooking worker standing in front of the range 1. The lower end of the suction duct 6 faces obliquely forward and opens forward as an intake port 10 at a rear portion slightly above the heating section of the range 1. Directly above the intake port 10 of this suction duct 6 is an eaves 11 that protrudes forward.
is installed to allow for changes in mounting height.
This eaves 11 is connected to the intake port 10 of the suction duct 6.
It has the functions of guiding the airflow to the airflow, changing the direction of the airflow by bending the outside air blown downward from the discharge port 8 diagonally forward, and functioning as a shelf on which articles are placed. That is, hook-shaped hanging structures 12 are provided on both side plates of the eaves 11, and the hook-shaped hanging structures 12 are attached to the hanging structures 13 that are provided on the sides of the suction duct 6 to project at intervals in the vertical direction. The top surface of the eaves 11, which is attached by hooking, has a slight downward slope in the installed state, but a plurality of mounting recesses 14 are formed on the top surface, the bottom of which is a horizontal surface in the installed state. The structure is such that the bottom side of the bottle 15 such as a food container can be fitted loosely and the bottle 15 can be placed stably.

Therefore, the ventilation fan of this example is designed so that the oil smoke, etc. rising upward from the range 1 during cooking is enveloped and diffused upward from the intake port 10 by the outside air bent by the eaves 11. It is suppressed, sucked into the air intake port 10, and efficiently discharged outdoors. At this time, since the direction of the buoyant force of the oil smoke and the like coincide with its suction direction, the exhaust fan 4 may be smaller in size than when the direction of the buoyant force and the suction direction are opposite to each other. And eaves 1 that actively function to discharge oil smoke, etc.
1 can be used as a shelf on which bottles 15 can be placed in a stable state without fear of them falling, so even if the suction duct 6 is on the wall on the upper back side of the microwave oven 1, it can be placed on the wall. does not become an unusable part. Note that reference numeral 17 in the figure indicates a filter.

[Effects of the invention] As is clear from the above explanation based on the embodiments, the ventilation fan of the invention consists of an air supply fan that sucks in outside air above the kitchen stove, a discharge port that blows outside air downward, an exhaust fan, and air. A duct is connected to the suction part, which has an intake port for sucking oil smoke, etc. from the range, at a position close to the range, and the above-mentioned discharge port is connected to the upper part of the intake port. An eaves is installed to bend the outside air blown downward from the roof and suppress the upward spread of oil smoke, etc.
Since the upper surface of this eaves is provided with a mounting recess into which the bottom of a seasoning container or the like can be loosely fitted, it prevents oil smoke, etc. from rising above the intake port and spreading along the direction of movement. The eaves and the flow of outside air bent by it can efficiently suck in and exhaust the outside air while preventing it from flowing outside air.
There is an advantage that the eaves can be used as a shelf to easily store seasoning containers and the like.
