Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction box used in a duct air conditioner for supplying air, the temperature and humidity of which are adjusted, to various parts of a room through a duct. In particular, the present invention relates to a suction box with an air purifying function, which incorporates an air purifier for removing fine dust and the like.

[0002]

2. Description of the Related Art FIG. 2 is a diagram showing an outline of a conventional duct air conditioner. The duct air-conditioning apparatus of FIG. 2 has a vent cap 16 for taking in outside air, a duct 7, an outside-air introducing fan 14, a suction box 11 for sucking indoor air, an indoor air-conditioning unit 17, and a branch chamber 1 from left to right in the drawing.
3. It is composed of an outlet 15 to each room. Among them, the indoor air conditioning unit 17 is provided with a fan for air circulation, a refrigerant coil, and a hot water coil, and the temperature and humidity of the air are adjusted.

In the conventional duct air conditioner of FIG. 2,
The following items were provided as those that fulfill the function of cleaning the air. That is, the air purifier and the suction box 11 optionally installed in the indoor air conditioning unit 17.
It was equipped with a simple filter (such as a saran net) that could be attached to the suction port or the air suction port.

[0004]

With the conventional simple filter, insects and large dust in the outside air and indoor circulating air can be removed, but pollen and fine dust cannot be removed. On the other hand, maintenance of the air purifier (cleaning of filters and periodic inspection of equipment) was troublesome when an air purifier was optionally installed in the indoor air conditioning unit. This is because the indoor air conditioning unit 17 is generally installed behind the ceiling 10 in the room. In addition, if an air purifier is originally installed in an indoor air conditioning unit that incorporates various types of equipment, restrictions (increase in dimensions, complexity of maintenance, etc.) when installing the indoor air conditioning unit in the ceiling become stricter. Was there.

An object of the present invention is to provide a suction box with an air cleaning function and a duct air conditioner which can remove fine dust and are easy to maintain.

[0006]

In order to solve the above-mentioned problems, an air purifying suction box of the present invention is a suction box used in a duct air conditioner, and comprises a box body and a first surface of the box body. Indoor air intake provided, a removable intake grill that covers the intake, an outside air intake port provided on the second side of the box body, and circulating air supply provided on the third side of the box body. Port,
And an air purifier installed facing the circulating air supply port.

[0007]

The air purifier in the suction box with an air purifying function of the present invention removes fine dust from the air (circulation air) sent from the duct air conditioner into each room. The circulating air is a mixture of room air sucked through the suction port and outside air sucked through the outside air suction port in the box body. The clean air from which fine dust has been removed is conditioned by an indoor air conditioning unit and sent to each room. If you remove the suction grill and put your hands in the suction box so that the air cleaner can be maintained, the maintenance work will be easier.

[0008]

EXAMPLES Examples of the present invention will be described below. Figure 1
It is sectional drawing which shows the suction box with an air purifying function concerning one Example of this invention. The box body 1 of the suction box with an air cleaning function has a rectangular box shape. Box body 1
The lower surface of is an indoor air suction port 21. An outside air suction port 23 is connected to the right side surface of the box body 1. A circulating air supply port 25 is connected to the left side surface of the box body 1. Room air entering the box body 1 from the room air intake port 21 and the outside air intake port 23
The outside air entering the inside of the box body 1 is mixed and sent from the circulating air supply port 25 toward the indoor air conditioning unit 17.

On the inner surface of the box body 1 connected to the outside air suction port 23, a prefilter 5 for outside air is provided so as to cover the port 23. A circulating air pre-filter 6 is also provided on the inner surface of the indoor air suction port 21 so as to cover the same. These pre-filters are equivalent to conventional simple filters and remove insects and large debris from the air.

Circulating air supply port 25 of the box body 1
The air cleaner 2 is installed near the port so as to cover the port 25. The air purifier 2 of this embodiment has an air purifier filter 4 and removes fine dust in the air. As the filter 4, specifically, an electric dust collector that charges and removes dust particles by adsorption, a filter in which a chemical deodorant is added to activated carbon, a combination thereof, or the like can be used.

A removable suction grill 3 is provided on the lower surface of the box body. If the grill 3 is removed, the air cleaner filter 4 can be easily removed (for cleaning) and the prefilters 5 and 6 can be easily removed.

[0012]

As is apparent from the above description, the air purifying suction box of the present invention exhibits the following effects. It is possible to remove pollen, fine dust, and the like that enter from the outdoors and dust and the like contained in the circulating air from the room, and improve the indoor air quality. Maintenance of the air purifier (periodic inspection of equipment, cleaning of filters, etc.) can be easily done from the inlet opening. The size of the indoor unit body can be reduced compared to an indoor unit with an air purifier. Since the suction box has an air cleaning function, the duct air conditioning system as a whole is excellent in installability, workability, and maintainability, and the system configuration becomes easy.
