Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to the structure of a ventilation system for exhausting oil smoke, steam, waste gas, etc. generated on a kitchen range to the outside.

[Conventional technology 1] Conventionally, this type of ventilation system has a structure in which a suction port is provided almost directly above the microwave table, and the upward airflow from the microwave is sucked in and discharged outside. there were.

However, in the ventilation system with this structure, the suction port is located at a predetermined height from the range, so oily smoke rising from the range tends to spread from the middle, and it takes a lot of people to exhaust such spread smoke. A powerful blower was needed. In addition, the efficiency of replacing and cleaning filters used in ventilation equipment is extremely poor because the ventilation equipment is located above the user.

Therefore, conventionally, as shown in the sectional view of the ventilation system in Figure 5, a suction port was provided at the rear of the cooking table.
The ventilation system shown in Publication No. 949 was used.

First, this conventional ventilation system will be explained.

[Problems to be solved by the invention] Since such a ventilation system sucks oily smoke generated during cooking without scattering it upward, an exhaust passage is formed on the back side of the cooking table (101). has been done. Therefore, the cooking table (101) must be placed in front of the cooking table (101) in order to provide space for the exhaust passage on the back side of the cooking table (101).

Furthermore, the space on the back wall of the cooking table (101) was not utilized effectively, resulting in poor space efficiency. Further, since the warm exhaust flow is discharged downward, there are problems such as a large exhaust blower (109) being required to sufficiently exhaust the air.

In addition, oil smoke generated during cooking is scattered and once it rises to the ceiling, it stays there.
Exhausting it was difficult.

This invention was made to eliminate the above-mentioned drawbacks, and an object thereof is to provide a ventilation device that can ventilate the air near the ceiling.

[Means for Solving Problems] The ventilation system according to the present invention is provided in a part of the door of a hanging cupboard provided in front of an exhaust fan and an intake fan provided above the range. The exhaust fan includes an opening and an intake port that communicates with the opening provided in the exhaust fan.

[Function] The ventilation system of the present invention exhausts the air near the ceiling through an opening provided in a part of the door of a hanging cabinet provided in front of an exhaust fan and an intake fan provided above the range. The air is guided to the intake port that communicates with the opening provided in the kitchen fan, and is discharged outside by the exhaust fan, making it possible to ventilate oil smoke generated during cooking that accumulates near the ceiling. Air purification becomes possible.

The above ventilation system operates the air supply fan motor (2) and the exhaust fan motor (7) by operating the switch (5).
) starts operating, and rotates the air supply fan (3) and exhaust fan (8), which are directly connected to the shafts of the respective motors.

In this state, when cooking is carried out using the pot (32) on the gas range (31), oily smoke, etc. passes from the suction port (16), passes through the filter (24), flows into the duct (14), and flows through the exhaust fan. (8), the air is discharged outdoors via the exhaust elbow (12).

In addition, the supply air passes through the supply elbow (11) from outdoors, is discharged from the discharge port (26) via the supply fan (3), and descends along the surface of the duct (14). 15) and changes the direction of the wind to the direction of the arrow (60). At this time, the oil smoke generated from the pan (32) is sucked in from the suction port (16), but the oil smoke on the front side is difficult to suck in and easily leaks outside, but the air supply flow is as shown by the arrow (60). Since the air is flowing, the oil smoke is engulfed by this supply air flow and sucked in from the suction port (16). At this time, the angle of the eaves is 5
Under the condition that the temperature is 10 degrees lower than
1/S, and the oil smoke is engulfed by this air flow and can be exhausted most efficiently.

By opening the outlet port (27) for the cooking worker, a part of the supplied air can be directly applied to the face and body of the cooking worker, thereby purifying the air in the cooking worker's environment. I can do it. In particular, it can reduce the heat during cooking in summer.

If the height of the pan (32) increases, remove the eaves 15) from the first step of the eaves hanger (39) and place it on the second step of the eaves hanger (40) or the third step of the eaves hanger (41). By hanging 15) on the eaves, the position of the eaves can be adjusted.

To treat dirt caused by oil smoke, a filter (24) installed in the duct (14) collects most of the oil smoke and purifies the exhaust air before discharging it.
4) Oil adheres to the inner wall and drips down the wall surface,
Dropped oil is collected and collected in an oil pool (17) provided integrally with the suction port (16) at the bottom of the duct (14). Therefore, oil treatment is generally done by screws (53).
Remove the integrated suction port (16) and oil sump (1).
7) is removed from the filter receiver, the filter (24) comes out from the duct (4), so the filter (24) can be cleaned and inserted back into its original position.

Also, if a large amount of oil adheres to the inner wall of the duct (14) as described above, the oil will accumulate in the oil pool (17), so the suction port (16) that was removed when cleaning the filter (24)
) and the oil pool (17), complete oil disposal can be achieved.

The fire shutter (25) operates by releasing a temperature fuse (
33) and the heat causes a temperature fuse (33).
melts and the force in the direction that was being lifted by spring B (36) becomes zero, so spring A (35) lifts the fireproof shaft V (
25) rotates about the fire shutter receiver (43) as a fulcrum, as shown by the two-dot chain line in FIG. 3, and hits the suction port (16). In this state, the air passage of the duct (14) is blocked by the fire prevention shutter (25), and the duct (14) is blocked from air passage by the fire prevention shutter (25).
4) Prevents flame from entering inside.

To reinstall the fire shutter (25), remove the suction port (16), replace the temperature fuse (33), and hook it onto the mounting plate B (37) using the spring B (36). and can be operated again.

Then, there is an opening (
61), and roughly, an intake port (62) is provided in a part of the front cover (29) of the fan, so that the air near the ceiling can also be drained from the opening of the door (59) of the hanging cabinet as shown by the arrow (63). Part (6
1) and the air inlet (62). In this way, the air near the ceiling can also be ventilated.

As shown in the above embodiment, there is a duct provided on the upper back wall near the range with a canopy at the inlet, an exhaust fan connected to the duct and provided above the range, and an exhaust fan provided above the range. In the case of a device that is equipped with an intake fan and an outlet that is connected to the intake fan and directs the outside air introduced by the intake fan through the duct surface and onto the eaves, the inlet part and the eaves are located near the range. Because it has a canopy, the smoke can be guided through the eaves and most of the smoke can be inhaled. The outside air from the outlet of the intake fan descends along the surface of the duct and hits the eaves, reducing its speed, which allows it to envelop the oil smoke. can be inhaled. The space on the back wall of the range can be used effectively, and the degree of freedom in designing the exhaust path to the outside is increased.

Further, a duct having a canopy at an inlet portion provided on an upper back wall near the range, an exhaust fan provided above the range connected to the duct, an intake fan provided above the range, and a duct provided above the range. a discharge port connected to an intake fan that directs the outside air introduced by the intake fan through the duct surface and onto the eaves; and a cooking sound discharge port that directs the outside air introduced by the intake fan to the cooking worker. In the case of a leak, we installed a duct with an inlet and a canopy near the oven, so most of the oil smoke could be sucked in, and the outside air from the intake fan's outlet could envelop the oil smoke. can be sucked into the duct roughly and well. Furthermore, since it can be discharged from the cooking worker outlet and directly applied to the cooking worker's face and body, the air in the cooking worker's environment can be purified.

[Effects of the Invention] As described above, according to the present invention, the opening provided in a part of the door of the hanging cabinet provided in front of the exhaust fan and intake fan provided above the range; Since it is provided with an intake port that communicates with the opening provided in the exhaust fan, the air near the ceiling can be ventilated and the indoor air can be purified.
