Abstract

(57) [Summary] [Purpose] I would like to obtain an air supply device that is devised so as not to reduce the collection efficiency of the range hood. [Structure] Attach an air supply grill 6 with the direction of the louver 8 facing away from the range hood 1 with respect to the air supply port 4, and detachably adjust the air supply air amount to approximately 50% of the filter 9 and exhaust air amount. Install the air supply volume adjustment damper 10.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an air supply device in a kitchen, which is devised so as not to reduce the collection efficiency of the range hood when exhausting air using the range hood.

[0002]

[Prior art]

 When a range hood is used, the exhaust air volume is large, which causes a negative pressure in the kitchen, which causes problems such as heating and cooling effects and the opening and closing of doors. Therefore, in general, a method has been adopted in which an air supply port is attached to a part of the kitchen and the outside air is taken into the kitchen from this air supply port to eliminate the problem of negative pressure.

[0003]

[Problems to be solved by the device]

 However, the conventional air supply port has the following drawbacks.

A. Since the air outlets and grills are blown out in all directions in the room, the airflow from these air inlets and grills directly reaches the updraft between the stove and range hood, and It has the drawback of disturbing and significantly reducing the collection effect.

B. Since the air supply volume is always constant, it is rarely maintained at about 50% of the ideal exhaust air volume.

C. Since the outside air is blown directly into the room, the dust in the outside air is brought into the room as it is.

An object of the present invention is to propose an air supply device in a kitchen in which the above-mentioned disadvantages a to c are solved.

[0008]

[Means for Solving the Problems]

 The structure of the present invention is as follows.

An air supply port is provided at a position distant from the range hood, and an air supply grill with a louver formed in the direction opposite to the range hood is attached to the air supply port, and a filter is detachably attached inside the air supply port. In addition, the air supply in the kitchen is equipped with a supply air volume adjustment damper that controls the air supply volume from the air supply port into the kitchen to be about 50% of the exhaust air volume exhausted from the range hood. apparatus.

The air supply grill may be replaced with the louver, or may have a configuration in which the opening on the range hood side is concealed so that the air supply does not blow out to the range hood side together with the louver.

[0011]

[Action]

 When the range hood is used, the damper or fan in the air supply passage is driven in conjunction with this, and the outside air is supplied to the room (in the kitchen) via the air supply port. At the time of this air supply, the air supply grill attached to the air supply port rises from the gas stove into the range hood because the louver or enclosure is formed at the air outlet to blow out air in the direction opposite to the range hood. It does not disturb the air flow. Also, since a filter is installed inside the air supply grill, dust and the like in the outside air are removed by this filter, and clean air is taken into the room. When the filter becomes dirty, it can be washed with water to keep it clean. In addition, the supply air volume is constantly controlled by the supply air volume adjustment damper to be approximately 50% of the exhaust air volume.

[0012]

【Example】

 FIG. 1 shows an embodiment of the present invention. 1 is a range hood, 2 is a gas stove, 3 is a ceiling, 4 is an air supply port provided on the ceiling 3, and the air supply port 4 and the outside are connected by an air supply duct 5. 6 is an air supply grill which is detachably attached to the air supply port 4, and a louver 8 is attached to the air outlet 7 of the air supply grill 6 so as to face the direction opposite to the position of the range hood 1. ing. 9 is a filter detachably attached to the air supply port 4, and this filter 9 can be washed with water. Reference numeral 10 is a supply air volume adjustment damper that adjusts the opening area of the supply port 4 so that the supply air volume becomes about 50% of the exhaust air volume. 11 is a spring, 12 is a damper mounting member, and 13 is a damper support shaft.

In the case of the above-mentioned embodiment, when the range hood 1 is used, outside air passes through the air supply duct 5 through the damper 10, the filter 9, the air supply grill 6, and the louver 8 in accordance with the negative pressure in the room, and And the louver 8 acts to blow it out of the range in the direction opposite to the range hood 1. As a result, the rising airflow between the gas stove 2 and the range hood 1 is not disturbed. The damper 10 adjusts the supply air volume to about 50% of the exhaust air volume.

[0014]

[Effect of device]

 The effects of the present invention are as follows.

A. Since the air flow from the air supply port is in the opposite direction to the range hood, it does not disturb the rising air flow between the gas stove and range hood. Therefore, the collection efficiency of the range hood can be improved.

B. A filter is installed inside the air inlet (grill), so dust in the outside air will not be brought into the room. Also, since this filter can be removed and washed easily with water, its function can be maintained for a long period of time.

C. By adjusting the supply air volume to about 50% of the exhaust air volume, the atmospheric pressure balance in the room is always kept optimal, so air conditioning is not compromised.
