JPH0525242U - Wind direction change device - Google Patents

Abstract

(57) [Summary] [Objective] The present invention relates to an air-conditioning device such as an air conditioner. The outlet area is not enough to reach the floor due to insufficient warm air resulting from a decrease in wind speed when the air volume at the outlet is low. The objective is to ensure comfortable air conditioning by ensuring the wind speed by reducing. [Structure] An outlet frame 6 and a shape that seals the inside of the outlet frame 6, has an opening 8 in the center, has a large louver drive shaft 9 on one side, and is pivotally supported by the outlet frame 6. A large louver 7 having a shaft through hole 10 on the other side and a shape for sealing an opening 8 of the large louver 7, and a small louver drive shaft 12 penetrating the shaft through hole 10 on one side and a large louver on the other side. A small louver 11 having a rotating shaft 13 pivotally supported by the louver 7 is provided.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a blowing direction air direction changing device for an air conditioner or the like.

[0002]

[Prior Art]

 Regarding the air-direction changing device on the outlet side of recent air conditioners, etc., in order to achieve comfortable air conditioning during heating, we have devised a method to maintain a constant wind speed in response to changes in air volume and to reach warm air to the floor.

A conventional wind direction changing device is disclosed in Japanese Patent Laid-Open No. 63-254345.

An example of a conventional wind direction changing device will be described below with reference to the drawings. FIG. 5 is a perspective view of a conventional wind direction changing device.

In FIG. 5, reference numeral 1 is a blowing frame. Reference numeral 2 denotes a louver, which has a rotating shaft 3 and a drive shaft 4 which are pivotally supported by the blowing frame 1. A motor 5 is directly connected to the drive shaft 4.

The operation of the wind direction changing device configured as described above will be described below with reference to FIG.

The motor 5 rotates the louver 2 via the drive shaft 4 to change the flow of wind from the upstream.

[0008]

[Problems to be solved by the device]

 However, with the above configuration, when the air volume is high, the wind speed is strong and warm air can reach the floor, but when the air volume is low, the wind speed is too low to reach the floor and comfortable air conditioning cannot be performed. It had drawbacks.

In view of the above problems, the present invention provides a wind direction changing device that can secure the wind speed even when the air volume is small.

[0010]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, an airflow direction changing device of the present invention has a blowout port frame, a shape for sealing the inside of the blowout port frame, an opening in the center, and a large louver drive shaft on one side. A large louver that is axially supported by the outlet frame and has a shaft through hole on the other side, and a small louver that has a shape that seals the opening of the large louver and that penetrates the shaft through hole on one side. A small louver having a moving shaft and a rotating shaft pivotally supported by the large louver is provided on the other side.

[0011]

[Action]

 According to the present invention, the large louver can be sealed even when the air volume is small and the small louver can be appropriately rotated to secure the wind speed and realize the comfortable air conditioning.

[0012]

【Example】

 A wind direction changing device according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a wind direction changing device according to an embodiment of the present invention, FIG. 2 is a sectional view taken along the line AA ′ of FIG. 1, and FIG. 3 is a sectional view taken along the line BB ′ of FIG. It shows the case where the large louver and the small louver are integrated. FIG. 4 is a sectional view taken along the line B-B ′ in FIG. 1 with the large louver sealed and the small louver appropriately rotated.

In FIG. 1, 6 is an outlet frame, and 7 is a large louver, which has a shape for sealing the inside of the outlet frame 6 and has an opening 8 in the center and a large louver drive shaft 9 on one side. It has an outlet frame 6 and is axially supported, and has a shaft through hole 10 in the other. A small louver 11 has a shape that seals the opening 8 of the large louver 7, and has a small louver drive shaft 12 penetrating the shaft through hole 10 on one side and a rotation rotatably supported by the large louver 7 on the other side. It has a moving shaft 13. A large louver motor 14 is a stepping motor directly connected to the large louver drive shaft 9, and a small louver motor 15 is a stepping motor directly connected to the small louver drive shaft 12.

The operation of the wind direction changing device configured as described above will be described below with reference to FIGS. 1 to 4.

The large louver motor 14 rotates the large louver 7 via the large louver drive shaft 9. Further, the small louver motor 15 rotates the small louver 11 via the small louver drive shaft 12. First, in the case of a strong wind, the large louver motor 14 and the small louver motor 15 are synchronously driven so that the large louver 7 and the small louver 11 rotate together as shown in FIG. Make a change.

Next, in the case of a weak wind, the large louver motor 14 is rotated to seal the large louver 7 as shown in FIG. 4, and then the large louver motor 14 is stopped. On the other hand, the small louver 11 can be freely rotated by the small louver motor 15. As a result, even if the air volume decreases, the outlet area is reduced and the wind speed is secured, warm air can reach the floor, and a comfortable air-conditioned space can be obtained.

[0018]

[Effect of the device]

 As described above, according to the present invention, the louver is divided into large and small parts, the large louver seals a part of the outlet, and the area of the outlet is reduced. It is possible to secure energy, achieve warm air to the floor, realize a comfortable air-conditioned space, and contribute to energy conservation by using energy without waste.
