Abstract

PURPOSE:To improve a design and enable a flowing direction of air discharged from a blowing port to be expanded by a method wherein a second lateral vane is rotated from its state in flush with a bottom surface of a main body to its substantial vertical state while a first lateral vane is kept in flush with a front surface of a main body. CONSTITUTION:A blowing port 9 arranged from a front surface 10 to a bottom surface 11 of a main body 1 is provided with a first lateral vane 13 in flush with the front surface 10 and a second lateral vane 14 in flush with the bottom surface 11 when an operation of an air conditioner is stopped, so that a blowing port 9 is not seen from a forward location and a downward location to improve a design. The lateral vanes 13 and 14 are rotatably supported. Since it is provided with a holding means 19 for keeping the lateral vane 13 in flush with the front surface 10 when the lateral vane 14 is rotated from its state in flush with the bottom surface 11 of the main body 1 to its substantial vertical state, it is possible to cause an air discharged from the blowing port 9 to positively flow along an interior wall surface 2. In addition, when the lateral vane 14 is rotated from its vertical state to its horizontal state, it is provided with a connecting means 17 for rotating the late vane 13, so that the air can be positively guided by the lateral vanes 13 and 14 from the blowing port 9 in a horizontal direction.

Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a device that is installed in an air conditioner or the like and changes the direction of cold or hot air.

(b) Conventional technology Air conditioners with air outlets extending from the front to the bottom of the main body are disclosed in Japanese Utility Model Publication No. 57-47648 and Utility Model Application No. 62-4974.
Like No. 0, a horizontal blade was rotatably supported at the outlet. If the horizontal blade is in a horizontal state, the air discharged from the outlet is guided in the horizontal direction, and if it is in a vertical state, the air discharged from the outlet is guided in the vertical direction. In addition, by placing the horizontal blades in a vertical position when the machine is stopped, the air outlet is not visible from the front of the main body, which improves the design of the main body.

(c) Problems to be Solved by the Invention There is a problem in that when the horizontal blades are placed in a vertical position, the air outlet is not visible from the front of the main body, but is visible from below the main body.

The present invention improves the design by completely closing the air outlet so that it cannot be seen from the front or below of the main body when the air conditioner is stopped, and also prevents air from being discharged from the air outlet when the air conditioner is in operation. The purpose of this is to expand the direction of air flow.

(d) Means for Solving the Problems In order to achieve this object, the present invention provides a vent provided from the front surface to the bottom surface of the main body that is flush with the front surface of the main body when the air conditioner stops operating. The first horizontal blade and the second horizontal blade are arranged flush with the bottom surface of the main body when the air conditioner is stopped.

Further, the first and second horizontal blades are rotatably supported, and when the second horizontal blade rotates from a state flush with the bottom surface of the main body to a state substantially perpendicular to the bottom surface of the main body, the first horizontal blade is rotated. A stopping means is provided to keep the second horizontal blade flush with the front surface, and when the second horizontal blade rotates from a vertical position to a horizontal position, the first horizontal blade is
The horizontal blades are also connected by a connecting means that allows rotation from a vertical position to a horizontal position.

(f) Action The air outlet provided from the front surface to the bottom of the main body is completely closed by the first horizontal blade located between the front surface of the main body and the road surface, and the second horizontal blade located between the bottom surface of the main body and the road surface state. do. In addition, while keeping the first horizontal blade flush with the front surface of the main body, the second horizontal blade can be rotated from a state flush with the bottom surface of the main body to a substantially vertical state, thereby allowing the air conditioner to be installed. flowing along the wall surface. Further, when the second horizontal blade rotates from the vertical position to the horizontal position, the first horizontal blade also rotates in accordance with this rotation.

(F) Embodiment In FIG. 1, 1 is a main body of an indoor unit of a separate air conditioner, and this main body is installed on an indoor wall surface 2.

3 is a suction port provided on the front of this main body, 4 is a heat exchanger built into this main body, 5 is a cross flow fan, 6 is a casing of this cross flow fan, and 7 is arranged below the heat exchanger 4. In the drain pan, a blowing part 8 is integrally formed below the drain pan.

In this Suita section 8, the Suita port 9 faces diagonally downward of the main body 1, and the air outlet 9 is connected from the front surface 10 of the main body 1 to the bottom surface 11.
spans over. At this Suita mouth 9, a first horizontal blade 13 is rotatably supported by a first support shaft 12 so that the front surface 10 of the main body 1 is in a state with the road surface, and a first horizontal blade 13 is rotatably supported so as to be in a state with the bottom surface 11 of the main body 1 and the road surface. A second horizontal blade 14 is arranged,
The support mechanism for these horizontal blades 14 is shown in FIG.

This FIG. 2 is a sectional view of the end of the air outlet WJ8, and 15 is a hollow second support shaft protruding from the inner wall 16 of the air outlet 8. A notch (connecting means) 17 is provided. Reference numeral 18 denotes an outer shaft fitted so as to wrap around the outside of the second support shaft 15, and a notch (holding means) 19 of about 90° is provided at the lower front of this shaft. An upper protruding piece 20 extending upward and a side protruding piece 21 extending laterally are formed around this outer axis. 22 is a first pin provided on the upper projecting piece 20, and a first connecting rod 23 extending upward is rotatably connected to this bottle. The first connecting rod 23 and the second connecting rod 24 are rotatably connected by a second bin 25.

This second connecting rod 24' is fixed to the first support shaft 12 of the first horizontal blade 13. A spring 27 is connected to a third pin 26 provided on the side projecting piece, and this spring 27 is fixed to the inner wall 16 of the Suita mouth 9. Reference numeral 28 denotes a rotating shaft of the second horizontal blade 14, which is fitted into the hollow portion of the second support shaft 15. 29 is a drive piece extending outward from this rotating shaft;
This drive piece 29 is located in the notch 17 of the support shaft 15 of @2 and the notch 19 of the outer shaft 18. The rotation shaft 28 of the second horizontal blade 14 is connected to the rotation shaft of a drive motor (not shown). When the drive motor is operated, the rotation shaft 28 of the second horizontal blade 14 moves in the direction of rotation of the clock hands, and the drive piece 29 moves between the two notches 17.
, 19 (see solid line arrow).

Next, the movements of these lateral blades will be explained with reference to FIGS. 2 to 6. First, when the operation is stopped, the first horizontal blade 13 is flush with the front surface 10, and the second horizontal blade 14 is flush with the bottom surface 11, as shown in FIG. In this way, the two lateral blades 13, 14 prevent the air outlet 9 from being seen from the front and from below when the operation is stopped.

Next, when operation is started, the rotation shaft 28 of the second horizontal blade 14 rotates in the direction of the solid line arrow in FIG. 3 due to the operation of the drive motor. At this time, the drive piece 29 of the rotating shaft 28
It also moves within the notch 17.19 of the second support shaft 15. Therefore, the first horizontal blade 13 remains vertical. That is, the second horizontal blade 14 is in contact with the bottom surface 11 and the road surface.
The first horizontal blade 13 remains in the vertical state (does not move) until it changes from the vertical state to the vertical state. When the second horizontal blade 14 is in the vertical state, the drive piece 29 hits the horizontal surface of the notch 19 of the outer shaft 18 (see FIG. 4).

After that, when the rotation shaft 28 of the second horizontal blade 14 further rotates (see FIG. 5), the drive piece 29 also moves upward (in the direction of the solid arrow).
The outer shaft 18 also rotates in the direction of the solid line. Due to this rotation, the first pin 22 of the upper protruding piece 20 of the outer shaft 18 starts to move downward, and with this movement, the first horizontal blade 13 is moved around the first support shaft 12 via the first connecting rod 23. Then, this horizontal blade 13 starts to move from the vertical direction to the horizontal direction. The first lateral blade 13 also moves parallel to the second lateral blade 14 until the second lateral blade 14 becomes approximately horizontal (see FIG. 6). Further, by performing an operation opposite to that described above, the Suita mouth 9 can be closed with the two transverse blades 13, 14. Here, since the outer shaft 1B is always biased by the spring in the direction of the broken line arrow in FIG.
The horizontal blade 13 also moves.

During cooling operation, as shown in Figure 6, the two horizontal blades 1
3.14 is in a horizontal state and the cold air is guided horizontally. Moreover, when the temperature of the air discharged from the Suita outlet 9 is low at the start of heating operation, or when the operation continues after the indoor temperature reaches the set value, the first horizontal blade 13 is placed in the vertical position as shown in FIG. If the second horizontal blade 14 is held and directed toward the indoor wall 2 (see Figure 1), the discharged air will flow along the indoor wall and will not stir the air in the room much, resulting in a feeling of cold air and It is possible to avoid giving the user a feeling of warm air. At this time the first
Since the horizontal blades 13 are maintained in a vertical state, the air discharged from the Suita outlet 9 is not discharged forward of the outlet 9.

(G) Effects of the Invention The present invention has a first horizontal blade that is flush with the front surface of the air conditioner when the air conditioner stops operating, which is provided at the air outlet provided from the front surface to the bottom surface of the air conditioner. Since the second horizontal blade is arranged so that it is flush with the bottom surface of the main body when the operation is stopped, the air outlet of this main body cannot be seen from the front or from below, resulting in a good design. Can be done.

Further, the first and second horizontal blades are rotatably supported, and when the second horizontal blade rotates from a state flush with the bottom surface of the main body to a state substantially perpendicular to the bottom surface of the main body, the first horizontal blade is rotated. Since the holding means is provided to keep the room flush with the front surface, the air discharged from the air outlet can be reliably flowed along the indoor wall surface. Furthermore, when the second horizontal blade rotates from the vertical position to the horizontal position, the first horizontal blade also rotates from the vertical position to the horizontal position. Wind can be reliably guided horizontally from the outlet.
