Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underfloor air conditioning blower having a function of blowing underfloor conditioned air into an ambient space.

[0002]

2. Description of the Related Art In recent years, as the number of office automation equipment has increased, the number of cases where the floor is a free access floor has been increasing in order to make the wiring easier. However, in order to secure a space in the height direction of an office, The number of underfloor air conditioners that house under the floor the air conditioners that used to be on the ceiling is increasing.

Conventionally, this type of underfloor air conditioning has a structure as shown in FIG. That is, the free access floor 102 was installed on the floor 101, and the floor-embedded blower 103 was installed on the free access floor 102 at a certain interval. The configuration of the blower 103 includes an electric motor 104, blades 105, a suction port 106, and a blowout port 10.
It consists of an outer shell 108 having 7. In addition, a floor blow-out type air conditioner 112 having an air conditioning inlet 110 and an air conditioning outlet 111 is installed in the living room 109.

In the above structure, the air conditioner 112 and the blower 1
When 03 is operated, the conditioned air is blown out from the air conditioning outlet 111 under the floor, passes through the suction inlet 106 of the blower 103, and is blown out from the outlet 107 to the living room 109. The return air is returned from the air conditioning suction port 110 to the air conditioner 112.

[0005]

In such a conventional underfloor air conditioning system, since the blower 103 is embedded in the free access floor 102 at a certain interval, depending on the arrangement of the desk 113, it may be close to the human 114. Since there is the air outlet 107 of the blower 103, the conditioned air directly hits the person 114, which causes discomfort, and if it is attempted to avoid it, there is a problem in that the degree of freedom in the furniture layout is lost.

The present invention is intended to solve the above problems,
By installing a blower with an opening / closing lid in the upper part of the main body and a suction port with an air chamber in the lower part, and placing an underfloor air-conditioning blower with an electric motor, blades and a casing inside the main part of the main body near the desk, It is an object of the present invention to provide an underfloor air conditioning system with high flexibility in layout.

[0007]

In order to solve this problem, the present invention relates to an air outlet having an opening / closing lid at the upper part of the main body outer casing,
A suction port having an air chamber is provided in the lower portion, and an electric motor, blades, and a casing are provided inside the outer shell of the main body.

[0008]

[Function] With this configuration, if the desk layout is determined, an underfloor air-conditioning air intake hole is opened in the floor near the desk, and an underfloor air-conditioning blower can be placed on top of it to realize underfloor air conditioning without discomfort. Becomes

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

As shown in FIG. 1, the blower 1 has an outer casing 2 having an upper portion provided with an outlet 4 having a rotatably movable outlet grill 3 attached thereto, and an inlet 6 having an air chamber 5 provided at the lower portion thereof. ing. An electric motor 7, vanes 8 and a casing 9 are provided inside the outer shell 2.

When the desk 12 is installed on the free access floor 11 installed on the floor 10, a hole 13 for taking in underfloor air-conditioning air is opened in the vicinity of the desk 12 so that the air chamber 5 covers it. 2 are installed. An underfloor blowout type air conditioner 17 having an air conditioning inlet 15 and an air conditioning outlet 16 is installed in the living room 14.

In the above-mentioned structure, if the blow-off grill 3 is opened with rotation, when the air conditioner 17 and the blower 1 are operated, the conditioned air is blown out from the air-conditioning outlet 16 to the underfloor, and the hole 13 provided on the free access floor 11 is opened. Is discharged from the suction port 6 to the air outlet 4 through the air chamber 5. Return air is returned to the air conditioner 17 from the air conditioning suction port 15. If the floor-embedded blower 18 is installed in a place without the desk 12 as shown in FIG. 2 and the blower 1 is installed near the desk 12 in the place where the desk 12 is present, it depends on the layout of the furniture. Without underfloor air conditioning. Air conditioner 1
7 and the blower 1 are not in operation, if the blow-out grill 3 on the upper part of the outer casing 2 of the blower 1 is rotated and closed, the dust in the living room 14 enters the blow-out port 4, and the blower 1 is next time.
It is possible to prevent dust from being blown out during operation, and the upper portion of the outer shell 2 is kept flat, so that the appearance is kept beautiful.

[0013]

As is apparent from the above description of the embodiments, according to the present invention, an air outlet having an opening / closing lid at the upper portion of the main body outer shell and a suction port having an air chamber at the lower portion are provided, and the electric motor is provided inside the outer shell of the main body. By arranging the underfloor air-conditioning blower provided with the blade and the casing near the desk, it is possible to realize an underfloor air-conditioning system with a high degree of freedom in the furniture layout.
