Description

Indoor components of air conditioners

technical field

The present invention relates to the structure of an indoor unit of an air conditioner.

Background technique

For example, JP-A-04-084042 discloses a conventional indoor unit of an air conditioner in which a panel is provided at an air intake port. Such an indoor unit is provided with an exhaust grille for exhausting air on the lower side of the front of the main body, and has a front panel for opening and closing the air suction port above the exhaust grille. In addition, the opening and closing device built into the main body opens and closes the front panel in the front-rear direction.

In this way, when the front panel is closed back and forth, the front panel moves substantially horizontally toward the front of the exhaust grill. Therefore, during the cooling operation, the cold air discharged from the upper portion of the exhaust grill hits the lower end portion of the front panel, thereby easily forming turbulent flow, and dew condensation is likely to occur in the vicinity thereof.

In addition, as an example of other prior art, Japanese Unexamined Patent Application Publication No. 2003-74896 discloses an indoor unit of an air conditioner that has a panel at the air intake port and a panel in front of a heat exchanger formed in a curved shape on the near side. Open and close drive mechanism.

In such an indoor unit, the depth of the main body is large, and when installed on a wall, the design has a certain sense of oppression, making it difficult to achieve a thin, smooth and aesthetically pleasing design.

In addition, as another conventional example, JP-A-2003-156228 discloses an indoor unit of an air conditioner shown in FIG. 7 . A front panel 22 is provided in front of the indoor unit main body (hereinafter referred to as the main body) 21, and a plurality of rib-shaped openings 22a are provided on the front panel 22, and these openings form suction ports for sucking air into the internal return air passage. . The display part 23 for displaying the operating state of the main body 21 is located above the blade 25 for changing the vertical wind direction provided at the outlet 24 of the wind and is provided in the approximate center of the main body 21 in the width direction. In addition, the display unit 23 is attached to the outer surface of the main body 21 so as to be visible at all times whether the main body 21 is in operation or not in operation.

In such a structure, since the opening 22a has irregularities, dust tends to adhere and it is difficult to wipe off. In addition, in order to sufficiently ensure the amount of air intake, a certain opening area is required, and thus there are many restrictions on design. In addition, since the display unit 23 is provided on the outer surface of the main body 21 and is usually exposed, even when the main body 21 is stopped, this part still has a strong influence on the design, making it difficult to achieve smooth aesthetics. taller design.

Detailed ways

Embodiments of the present invention will be described below with reference to the drawings. In each embodiment, parts having the same structure and the same actions are given the same symbols as those in the previous embodiments, and their detailed descriptions are omitted.

(Example 1)

Fig. 1 is a cross-sectional view of the main body 1 of the indoor unit in the air conditioner of the present invention when the operation is stopped, and Fig. 2 is a cross-sectional view when it is in operation.

Inside the main body 1, a heat exchanger 2, a fan 3, and an exhaust grill 5 are installed. While communicating with the exhaust grill 5, a wind direction changing vane (hereinafter referred to as vane) 6 for vertically changing the direction of the discharged air is provided at the exhaust port 5b that blows cold or warm air to the outside.

A front panel 4 is provided on the front of the main body 1, and the front panel 4 is connected to the main body 1 through a support member 7 rotationally driven by a driving device not shown in the figure. No opening for intake air is provided on the front panel 4 .

As shown in FIG. 1 , when the operation is stopped, by rotating the supporting member 7 counterclockwise and shortening it, the front panel 4 is closed and comes into close contact with the main body 1 . At this time, the lower end 4a of the front panel 4 is located below the upper end 5a of the exhaust port 5b.

During operation, as shown in FIG. 2 , by extending the support member 7 by rotating clockwise, the front panel 4 moves forward and upward to open. The lower end 4a of the front panel 4 is located at a height B higher than the upper end 5a of the exhaust port 5b.

The operation and function of the air conditioner having the above structure will be described below. During operation, the front panel 4 moves forward and upward. Through the rotation of the fan 3 , indoor air is sucked in through the gaps between the front panel 4 positioned in front of the main body 1 and the top, side and bottom of the main body 1 . The heat exchanger 2 performs heat exchange on the sucked air to form cold air or warm air. The temperature-regulated air flows through the exhaust grill 5 and the exhaust port 5b, changes the exhaust angle through the blades 6, and is exhausted into the room.

When cooling air is supplied, if there is an obstacle or the like in front of the cold air discharged from the exhaust port 5b, it will hit the obstacle and form a turbulent flow, thereby easily generating dew condensation. In the embodiment of the present invention, as shown in FIG. 2, the lower end 4a of the front panel 4 is located at a position higher than the upper end 5a of the exhaust port 5b by a height B. Therefore, it is difficult for cold wind to hit the lower end 4a, thereby preventing the occurrence of dew condensation.

In addition, when the operation is stopped, as shown in FIG. 1 , the lower end 4 a of the front panel 4 is located at a position lower than the upper end 5 a of the exhaust port 5 b by a height A. Therefore, the upper end 5a of the exhaust port 5b pasted with nonwoven fabric or the like is concealed, thereby improving appearance.

In addition, according to the embodiment of the present invention, since there is no opening for air input on the front panel 4, dust accumulation does not occur, so that it is easy to clean, and an aesthetically excellent design can be implemented.

(Example 2)

Fig. 3 is a cross-sectional view of the main body 1 of the indoor unit in the air conditioner, and the front panel 4 in the open state is marked with a solid line, and the front panel 4 in the closed state is marked with a double-dashed line. Fig. 4 is a front view of the main body 1 when the operation is stopped. In this embodiment, a display unit 8 indicating the operating state of the air conditioner is provided at the front of the water receiving container (not shown in the figure) of the exhaust grill 5 . In addition, the display unit 8 is hidden from view when the operation of the main body 1 is stopped, and is located at a position where it can be seen from the front and bottom during operation. The structure other than that is the same as in Example 1.

Specifically, when the operation is stopped, the lower end 8a of the display portion 8 is located at a position higher than the lower end 4a of the front panel 4 by a height C when the main body 1 is viewed along the arrow direction 9 at the front and downward. Panel 4 is concealed. During operation, when the main body 1 is observed along the arrow direction 9 of the front and bottom, since the lower end 8a of the display portion 8 is located at a position lower than the lower end 4a of the front panel 4 by only a height D, it is easier to recognize the display from the front and lower. Part 8.

As described above, according to this embodiment, since the display unit 8 is hidden inside the front panel 4 when the operation is stopped, the appearance of the air conditioner is improved.

(Example 3)

FIG. 5 is an enlarged view of a pair of support members 12 and their mounting parts for connecting the front panel 4 to the main body 1 when the front panel 4 is opened.

The support member 12 has a first support plate (hereinafter referred to as a support plate) 14 and a second support plate (hereinafter referred to as a support plate) 15 . One end and the other end of the support plate 14 are rotatably supported by the main body 1 and the front panel 4 via shafts 14a, respectively. One end and the other end of the support plate 15 are installed in the groove-shaped or long-hole-shaped receiving part 1b provided on the main body 1 and the groove-shaped or long-hole-shaped receiving part 1b provided on the front panel 4 through the shaft 15a to rotate and slide freely. In the receiving part 4b. The support plate 14 and the support plate 15 are rotatably connected by a shaft 13 substantially at the center.

The gear 11 a integrally rotates the support plate 14 . By means of the gear 11b, the drive device 11 rotates the drive gear 11a. The structure other than that is the same as in Example 1.

With the above structure, when the operation is stopped, the support plate 14 is rotatable in the counterclockwise direction by the gears 11a, 11b which are rotationally driven by the driving device 11. As shown in FIG. Then, the shafts 15a located at both ends of the support plate 15 slide while rotating, and move so as to separate from each other in the vertical direction, and the support plate 14 and the support plate 15 overlap. Therefore, as shown in FIG. 6 , the front panel 4 is in close contact with the main body 1 .

In addition, during operation, if the driving device 11 rotates the support plate 14 clockwise by means of the gears 11b, 11a, the shafts 15a positioned at both ends of the support plate 15 move in a vertically approaching manner. Therefore, as shown in FIG. 5, the support plates 14, 15 are opened.

At this time, since the rotation center of the shaft 14 a on the side of the main body 1 in the support plate 14 is fixed, the front panel 4 moves forward and upward of the main body 1 .

Therefore, according to the present embodiment, the support member 12 adopts a simple structure composed of two parts, thereby reducing the cost and weight.

Also, in the present embodiment, the shafts 15a provided at both ends of the support plate 15 are received by grooves or slot-shaped receiving portions 1b, 4b provided in the front panel 4 and the main body 1 . In addition, the opposite structure can be adopted, that is, even if grooves or slot-shaped receiving parts are provided at both ends of the support plate 15, and shafts are provided on the front panel 4 and the main body 1, the same effect can still be obtained.

Next, the driving device 11 will be described. The driving device 11 is arranged in the space surrounded by the front part 1d of the main body 1, the top part 1c, and the heat exchanger 2 inclined to the rear of the main body at the upper part of the front side, and cooperates with the heat exchanger 2. Since the drive device 11 is provided in this space, miniaturization of the main body 1 is achieved.

In the above structure, the drive device 11 is provided inside the heat exchanger 2 at substantially the highest portion and the front portion, and the shaft 14 a is provided substantially above the drive device 11 . Therefore, during operation, when the drive gear 11b rotates, the drive is first transmitted to the connected gear 11a to rotate the shaft 14a on the main body 1 side. In addition, the support plate 14 is rotated clockwise to move the front panel 4 upward. By arranging the components in this way, it is possible to reduce the size of the drive mechanism, reduce the thickness of the main body 1, and form a smooth, high-design design.

As described above, in the air conditioner of the present invention, the front panel 4 has no opening, and thus has a high aesthetic design. In addition, since there are no surface irregularities such as ribs, it is difficult to get dirty, and even if it is dirty, it is easy to wipe off and clean. In addition, since the cold air discharged from the exhaust port is less likely to hit the lower end of the front panel, dew condensation is also prevented. Therefore, it can also be applied to applications such as houses that require high interior decoration.
