Abstract

PURPOSE:To obtain such environment for air conditioning that is most suitable for the construction of a room in which an air conditioner is provided, by accommodating rotatable toroidal plate having an opening and a blocking part in a toroidal outlet port formed on the outer periphery of an air inlet, blowing air flow from a outlet port in any direction depending on the position of the opening of the toroidal plate. CONSTITUTION:When a fan 2 rotates by operating a motor 4, the indoor air drawn through an inlet 5 passes through an air filter 10, a guide cylinder 7, and an inducing plate 15 to coils 3. The indoor air is heat exchanged in the coils 3 and flows down between a casing 1 and a guide plate 6a and then passes through openings 16a of a toroidal plate 16 to be discharged through a outlet port 8 into the inside of a room. Since the toroidal plate 16 is provided rotatably in the discharge passage, the air flowing out from the outlet port 8 can be discharged in any direction through 360 deg. depending on the position of the openings 16a, whereby optimum environment for air conditioning will be attained. Further, in the case of a rectangular room, effect of air conditioning is improved by concentrating air flows in the direction of a longer side of the room; therefore, blocking plates 16b-1, 16b-2 are moved and fixed within the toroidal plate 16 so that the openings 16a have optimum discharge area.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an air conditioner that improves the tendency of air to blow into a room.

[Conventional technology]

Conventionally, a cassette type air conditioner is known as an air conditioner. This type of air conditioner has one-way suction, one-way blowout, one-way suction, two-way blowout, one-way suction, four-way blowout, etc.

FIG. 9 is a sectional view showing a conventional air conditioner disclosed in, for example, Japanese Utility Model Application Publication No. 58-133722.

), the drain pan is installed at the bottom of Q (l is the suction port (5)
The air filter installed inside, C1υ is the air outlet (8
) is installed on the outer circumference of the wind guide.

Next, the operation will be explained. The blower (2) is rotated by the drive of the motor (4), and indoor air is sucked in from the suction port (5), passes through the air filter 〇〇, and enters the suction introduction tube (6).
After that, it is sprayed onto the coil (3). This indoor air undergoes heat exchange with the coil (3), passes between the casing m and the introduction tube (6), and is blown out into the room from the outlet (8). , = Drain generated during heat exchange with the fill (3) is collected in the drain pan (9) and discharged to the outside.

[Problems to be Solved by the Invention] Since the conventional air conditioner is configured as described above, the air blown into the room is blown out from the entire circumference of the air outlet (8). This method of blowing air is ideal for cooling, but when heating, it is difficult for the blown air to reach the floor. Therefore, in order to reach the floor surface, it is possible to narrow the opening size of the air outlet (8) to increase the blowing air speed, or increase the rotation speed of the blower (2) to increase the amount of air flowing in. . However, in the former case, the pressure drop at the outlet becomes large, and the rotational speed of the motor must be increased, resulting in a problem of increased noise. .

In addition, even when the wind from the blowout reaches the floor, 360
There were also problems such as feeling the wind in the direction of ゛.

This invention solves the above-mentioned problems, and also takes into account the condition of the room in which the air conditioner is installed [■ the height of the room, the shape of the room (elongated room, nearly square room, etc.), the air conditioner for the room In "Position".

The purpose is to obtain air conditioning +p1 that allows optimal air conditioning.

[Failure to resolve the issue]

The air conditioner according to the present invention is provided with a rotatable annular plate having an opening and a closing part in an annular outlet provided on the outer periphery of an inlet, and the area of the opening of the annular plate and the closing part are adjusted. The part area can be changed arbitrarily.

[Effect]

Since the air conditioner according to the present invention rotatably accommodates an annular plate having an opening and a closing part in the air outlet, the direction of the air blown into the room can be arbitrarily changed.

An optimal air-conditioned environment can be obtained.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure and FIG. 2, (l) is a round cylindrical casing, and (2) is a blower, which is rotated by a motor (4). (3) is a coil with a heat exchange function arranged around the outer circumference of the blower (2), and (5) is a suction port for sucking indoor air by the blower (2), which is integrated with the suction introduction tube (6). Consists of a drawn guide tube (7).

A baffle plate (6a) is provided behind the guide tube (7) and forms a blowout passage together with the casing (1). (8) is an annular outlet formed between the suction introduction tube (6) and the casing (11), and (9) is a drain pan provided at the bottom of the coil (3).

The recess is an air filter installed inside the suction port (5).

In addition, +lυ is a guide plate provided between the outer periphery of the air outlet (8) and the ceiling surface tia, uJ is an anchor bolt supporting the casing (1) on the ceiling slab α core, (15 is the suction port (
This is a guide plate for guiding the indoor air sucked in from 5) to the coil (3).

The problem lies in the annular plate disposed inside the air outlet (8), that is, in the air outlet passage between the casing (1) and the suction introduction pipe (6), and this annular plate ub+ has a long length as shown in Figures 4 to 6. Hole-like openings (+6a) and closing parts (16b) are provided alternately. And the closing part (16b) is a closing plate (t6b-1) (
16b-2), and are constructed so that they can be freely moved and fixed to each other. In addition, a groove (16C) is formed on the outer peripheral surface of the annular plate tui. The annular plate (lfi) constructed in this way is such that the concave groove (16C) on the outer ffA surface is connected to the protrusion (1a) provided on the casing (1) as shown in Fig. and the four parts α formed on the baffle plate (6a)
η is fitted and held for one full rotation.

In the air conditioner of the present invention configured as described above, when the blower (2) is rotated by the drive of the motor (4), the indoor air sucked through the suction port (5) is filtered through the air filter (
11, and is sent to the coil (3) via the guide tube (7) and the guide plate. And this indoor air is connected to the coil (3
), the casing (1) and the baffle plate (6=1)
Flows down between the holes and passes through the opening (+6a) of the annular plate 2.
The air is blown into the room from the air outlet (8). Thus, since the annular plate 1llf9 is rotatably provided within the blowout passage,
The wind that blows out from the outlet (8) depends on the position of the opening (+6a).

The air can be blown in any direction within 360', thereby providing an optimal air-conditioned environment. moreover.

Depending on the shape of the room in which it is installed, for example, in the case of a rectangular room, the air conditioning effect will be better as the air blowing lice will be concentrated in the long side direction.

The closing plates (+ab-1) (+6b-2) are moved and fixed within the annular plate so as to form the opening (16a) that provides the optimum blowout area. The same thing can be said when the ceiling of the room is high. Furthermore, in a deformed room, if you want to blow out the air in one plane direction instead of diagonally, you can collect the blocking plates (16b-1) (16b-2) in one direction to improve the air outflow. This results in an optimal air-conditioned environment.

In addition, as shown in FIGS. 7 and 8, baffle plates σ9 attached to both ends of the arm aa along the inside of the air outlet (8) can be rotated instead of the annular plate αe, as shown in FIGS. 7 and 8. The same effect can be obtained even if the baffle plate is expanded and contracted.

[Effects of the Invention J As explained above, according to the present invention, a rotatable annular plate having an opening and a closing portion is housed in the annular outlet formed on the outer periphery of the inlet.

Depending on the position of the opening in the annular plate, the air from the outlet can be blown out in any direction, and it is also possible to obtain an air-conditioned environment that is optimal for the structure of the room in which it is installed.
