Abstract

PURPOSE:To permit to branch blow-off airflow into two directions and obtain a comfortable living space having uniform temperature distribution by a method wherein a main airflow direction changing louver and an auxiliary airflow direction changing louver, located at the intermediate position of a blow-off port, are provided in the device. CONSTITUTION:The main airflow direction changing louver 7 of the airflow direction changing device 5 is secured to a rotating shaft 6 at the center of shorter direction of the louver. The auxiliary airflow direction changing louver 8 is wound around a part of the rotating shaft 6 and is pivoted under locating at the upper surface side of the main louver 7. In the case of horizontal blow-off, the main louver 7 is positioned horizontally and the auxiliary louver 8 is contacted with the main louver 7a. In this case, airflow passes in parallel to the main louver 7. When the blow-off airflow is to be branched into two directions upon room heating, the main louver 7 is set so as to face to downward direction, the auxiliary louver 8 is pivoted toward the side of the main louver 7b and is stopped at a place whereat the louver 8 is abutted against a stopper 10. According to this method, the airflow, passing through the lower side of the main louver 7 is blown off downwardly while the direction of airflow, passing through the upper side of the main louver 7, is changed by the auxiliary louver 8 and the airflow is blown off into the horizontal direction, thus, the blow-off airflow may be branched into two directions.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a wind direction changing device that is used in an air outlet of an air conditioner or the like and changes the wind direction arbitrarily, and particularly relates to a wind direction changing louver that can divide the blowing air into two directions. related to.

Conventional Structure and Problems Conventionally, a wind direction changing louver used in an air outlet of an air conditioner or the like has been structured as shown in FIG.

That is, a is a ceiling-suspended air conditioner main body, an interior Vc is a kite-sakaki fishing device C, and a wind direction changing device e is disposed between the air outlet d. The wind direction changing device e consists of a rotating shaft f and a wind direction changing louver q fixed to the rotating shaft f, and by rotating the wind direction changing louver q and changing the angle, the blowing direction can be changed from a horizontal direction to a point close to a vertical direction. It can be changed. However, since the blowing direction is unidirectional, the specific gravity of the warm airflow during heating is light, so even the wind that blows downward will be directed toward the ceiling on the way, meaning that the back of the room will not be warmed, which means that the temperature distribution in the room will be affected. It had the disadvantage that it was not uniform.

OBJECTS OF THE INVENTION Therefore, an object of the present invention is to provide a wind direction changing device that can divide the blown air into two directions in order to enable uniform temperature distribution in a space to be air-conditioned.

Structure of the Invention In order to achieve this object, the present invention provides an air flow system that, when the main wind direction changing louver fixed to the rotating shaft located in the middle of the air outlet is directed downward, the rotating shaft of the main wind direction changing louver is shared and the main wind direction changing louver becomes independent. An auxiliary airflow direction changing louver that can be rotated horizontally divides a portion of the blown airflow, creating a uniform temperature distribution in the space to be air-conditioned using airflow in two directions.

DESCRIPTION OF THE EMBODIMENTS An example in which an embodiment of the present invention is applied to a ceiling-suspended air conditioner will be described below with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 denotes a ceiling-suspended air conditioner main body, in which a blower 2, a heat exchanger 3, and a wind direction changing device 6 are arranged between an air outlet 4.

Furthermore, details of the wind direction changing device 6 will be explained according to FIGS. 3 and 4. 6 is a rotating shaft, both ends of which are supported by one air conditioner main body and can rotate. 7 is the main wind direction changing louver (
Hereinafter, it will be referred to as the main louver. ), and is fixed to the rotating shaft 6 at the center in the lateral direction.

Note that the windward part of the main louver 7 is 7a, and the leeward part is 7a.
b. Reference numeral 8 denotes an auxiliary wind direction changing louver (hereinafter referred to as an auxiliary louver), which wraps around a part of the rotating shaft 6, is located on the upper surface side of the main louver 7, and rotates. Reference numeral 9 denotes a winding portion which is integrated with the auxiliary louver. The stopper 1011′i is located near the wrapping portion of the auxiliary louver 8, and is integrated with the main louver 7 at the cut and raised portion of the main louver 7.

Next, the wind direction changing operation in the above configuration will be explained in detail.

First, in the case of the horizontal blowing direction, the main louver 7
As shown in the figure, the auxiliary louver 8 is placed horizontally, and the auxiliary louver 8 is in close contact with the main louver 7a. At this time, the airflow passes through the upper surface side and the lower surface side of the main louver 7 in parallel, resulting in a horizontal blowout state which is the same as before.

Next, in order to divide the airflow into two directions during heating, set the main louver 7 downward as shown in FIG. 5, rotate the auxiliary louver 8 toward the main louver 7b,
Stop when it hits 0.

As a result, the airflow passing under the main louver 7 is blown downward as before, and the airflow passing above the main louver 7 is attracted by the airflow and directed downward, but the direction of the air is changed by the auxiliary louver 8 and it blows horizontally. As a result, the blown airflow is divided into two directions. Therefore, since the horizontal airflow has a certain speed, it reaches the back of the room and descends downward, making it possible to obtain a uniform temperature distribution in the space to be air-conditioned.

Effects of the Invention As is clear from the above description, the present invention provides an interaction between a main wind direction changing louver fixed to a rotating shaft located in the middle of the air outlet, and an auxiliary changing louver that can be rotated by sharing the rotating shaft. This allows the blown airflow to be divided into two directions, making it possible to obtain a comfortable living space with uniform temperature distribution.
