Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner including an indoor unit and an outdoor unit, and more particularly to a panel drive structure in which an intake port of the indoor unit can be opened and closed.

[0002]

2. Description of the Related Art An air conditioner composed of an indoor unit and an outdoor unit is widely used. In the indoor unit, the main body is provided with a suction port and a blowout port, and a heat exchanger, a blower and the like are housed inside the main unit.

A louver is provided at the blow-out port so that the air can be blown out in an optimum direction according to the switching between the cooling operation and the heating operation. For example,
During the cooling operation, the cool air does not hit the horizontal direction almost directly, and during the heating operation, the warm air is blown to the feet so as to generate so-called head cold foot heat.

On the other hand, in the case of the suction port, a grill is provided to shield the inside of the main body from the room so that the inside cannot be seen through the suction port. Substantially, the suction port is in a completely open state, which makes it easy for dust to enter, especially when the operation is stopped.

As a third means, the air conditioner main body portion provided with the suction port has a curved portion in which a part is a flat portion to which the link member is mounted and the remaining portion projects toward the front side, The mouth is opened in the width direction of the air conditioner body, the panel is a curved shape protruding toward the front side with a gap from the flat portion of the air conditioner body, and It is bent from the width direction to both sides.

As a fourth means, the opening / closing drive mechanism is
The panel is driven so that one side portion in the direction orthogonal to the width direction of the suction port is opened more than the other side portion.

As a fifth means, the link member has two links having different lengths, and one link is formed longer than the other link.

As a sixth means, one of the links having different lengths is a drive side link whose one end is connected to the drive shaft, and the other link is the drive side link. The driven side link is driven in a direction opposite to the rotating direction.

As a seventh means, the driving side link and the driven side link are respectively provided with gear portions, and the gear portions mesh with each other to transmit the driving force.

As an eighth means, an elastic force is applied to the driving side link and the driven side link in the closing direction of the panel by an elastic member.

In the indoor unit of the air conditioner thus configured, as shown in FIG. 1 again, the movable panel 6 closes the front suction port 3 when stopped, and the suction port 3 is closed. Therefore, no dust enters inside the unit body 1. The outlet 7 is also closed by two outlet louvers 8A and 8B.

When the operation switch of the remote controller is turned on, the opening / closing drive mechanism 5 operates to move the movable panel 6 to the front side, and the front suction port 3 is opened, as described later.
7 is a side view of the movable panel 6 with the front suction port 3 opened, FIG. 8 is a side view of the indoor unit in the same state, and FIG. 9 is a perspective view of the indoor unit in the same state.

A blowout louver 8 provided at the blowout port 7.
A and 8B have the outlets closed in the state shown in the figure,
A predetermined amount of rotation is performed according to the switching setting between the cooling operation and the heating operation. While the blower 11 performs a blowing action, the compressor of the outdoor unit is driven and the refrigeration cycle operation is started.

Room air is introduced into the unit main body 1 through the upper suction port 2 and the front suction port 3, and the air filter 1
Pass 5. The dust contained in the indoor air is captured by the air filter 15, and the heat exchanger 9 is removed with the dust removed.
A heat exchange action is carried out through.

This heat exchange air is guided along the blowout air passage 14 and blown out from the blowout port 7 louvers 8A, 8B.
And is blown out into the room for efficient air conditioning operation.

The electrostatic precipitator 10 operates to completely trap dust not trapped by the air filter 15.
Therefore, the purified air is blown into the room through the heat exchanger 9 through the blowout port 7.

When the operation switch of the remote controller is turned off to end the air conditioning operation, the operation of the compressor, the blower 11 and the electrostatic precipitator 10 is stopped, and the opening / closing drive mechanism 5 moves the movable panel 6 backward to move the front suction port. 3 is closed.

Next, the operation of the opening / closing drive mechanism 5 will be described. In the opening / closing drive mechanism 5 when the movable panel 6 closes the front suction port 3, the upper side link 23A and the lower side link 23B constituting the link member 20 are in a vertical state, and it is as if one straight line. It looks like a torn link.
Almost half of the links 23A and 23B are flat parts 1 of the main body.
It is inserted into the concave portion 30 formed in A, and the other half projects from the flat portion 1A.

At this time, the pin portion 27b at the lower end of the lower side link 23B is engaged with the lowermost portion of the hole portion 29b formed of the elongated hole of the lower side engaging member 28B. Each engagement member 28A,
28B is drawn closest to the main body 1 side, and the movable panel 6 including the engaging members 28A and 28B completely closes the front suction port 3.

Air-conditioning operation is started by turning on the operation switch of the remote control, and at the same time, the drive source 22 of the opening / closing drive mechanism 5 drives the drive shaft 21 to rotate counterclockwise in FIGS. 1 and 2.

The upper link 23A pivots so that the upper end of the upper link 23A projects forward against the elastic force of the upper torsion spring 24, and the lower link 23B passes through the gear parts 26a and 26b.
The rotational force is transmitted to.

The lower side link 23B rotates so that the lower end thereof projects forward, against the elastic force of the torsion spring 24 on the lower side. As described above, the rotation angles of the upper and lower links 23A and 23B at this time are the same.

When the drive shaft 21 is rotated by a predetermined amount, the drive source 22 is stopped. Upper and lower links 23A, 23B
Rotate in a direction in which their respective upper and lower ends approach each other, and have a substantially V-shape.

Each link 23A, 23B and engaging member 28
The movable panel 6 projects and moves toward the front side through A and 28B, and the front suction port 3 is opened. In this state, the pin portion 27b at the tip of the lower link 23B has the lower engaging member 2
It engages with the upper end of the hole 29b formed of a long hole of 8B.

The total length La of the upper side link 23A is set longer than the total length Lb of the lower side link 23B, the upper side engaging member 28A is provided with a hole portion 29a formed of a round hole, and the lower side engaging member 28B is provided with a long hole. The movable panel 6 moves so as to open the upper side of the front suction port 3 more largely than the lower side because of the configuration including the hole portion 29b.

Specifically, as shown in FIGS. 7 and 8, the distance Sa between the upper edge of the movable panel 6 and the front panel 4 is Sa.
Is the distance Sb between the lower edge of the movable panel 6 and the front panel 4.
(Sa> Sb).

Usually, the indoor unit is mounted on the wall surface of the living room at a high place near the ceiling. Therefore, the resident almost looks up at the indoor unit from below. Under these conditions, the movable panel 6 is opened (Sa> Sb) during air conditioning operation, and the front intake port 3 is opened. It looks nice and looks good.

In particular, as shown in FIGS. 8 and 9, when both side portions 6a of the movable panel 6 are bent along the both side portions of the unit main body 1 and the front suction port 3 is opened. However, both sides 6a of the movable panel 6 are the unit main body 1
It only moves along the sides of.

That is, although both sides of the front suction port 3 are closed by the movable panel 6, the above (Sa> Sb) is satisfied.
As a result, a sufficient suction space is secured and the amount of air to be heat-exchanged is sufficient. Then, since the suction from the upper side becomes the main flow, the convection effect in the room can be enhanced.

In the opening / closing drive mechanism 5 when the air conditioning operation is stopped again, after the pin portion 27b of the lower link 23B moves through the hole portion (oblong hole) 29b of the engaging member 28B, the engaging member 28B is removed. Pull up.

Because of the difference in the total length of the upper and lower links 23A and 23B, the amount of movement of the upper and lower engaging members 28A and 28B and the upper and lower portions of the movable panel 6 is proportional to the opening amount of the front suction port 3, and finally the front. The part suction port 3 is closed.

As described above, the front suction port 3 can be opened and closed by the movable panel 6, and the front suction port 3 is completely closed when the operation is stopped to prevent dust from entering the main body 1 and to cause various problems. There is no.

Further, the link member 20 and the drive shaft 21 constituting the opening / closing drive mechanism 5 can be arranged in a small space between the flat portion 1A of the front panel 4 and the back side of the movable panel 6, and the main body has a simple construction. Promote miniaturization of.

Since the front panel 4 and the movable panel 6 are curved, and the movable panel 6 is bent from the front surface to both sides, the mechanism for varying the opening amounts of the upper and lower portions of the front suction port 3 is simple. Turn into.

As the link member 20, two links 23 are provided.
A and 23B are provided, and one link 23A is used as a drive side,
Since the other link 23B is on the driven side, the mechanism can be simplified and can be configured with the minimum necessary parts. There is no problem even if the drive side link and the driven side link are set to opposite links.

Each of the links 23A and 23B has a gear portion 26a. Since 26b is provided and meshes with each other, the transmission of the driving force is smooth and there is no waste. An elastic member (torsion spring) 24 is provided between the front panel 4 and the link member 20 to apply an elastic force to the link member 20 in the closing direction of the suction port 3 of the movable panel 6.

The direction in which the elastic force is applied is opposite to the direction in which the movable panel 6 moves to open the front suction port 3 due to gravity. That is, due to the presence of the elastic member 24, the opening operation of the movable panel 6 does not need to be rapid. Further, the driving torque required for the closing operation of the movable panel 6 can be smaller than that in the case without the elastic member.

Since a plurality of sets of link members 20 are provided and engaged with one drive shaft 21 and all the link members 20 are simultaneously urged to rotate with the rotation of the drive shaft 21, There is no waste in the operation as the link mechanism, and since the operation is completely synchronized, the moving posture of the movable panel 6 is not distorted.

That is, while the front suction port 3 has an extremely large length in the width direction as compared with the vertical direction, the movable panel 6 can be opened and closed in the vertical direction without being distorted in the width direction, which is high. Opening and closing accuracy can be obtained.

Since the link member 20 is fitted on the drive shaft 21 and does not move along the drive shaft 21, rust may occur on the drive shaft 21 even if it is used for a long period of time. Even if there is, there is no hindrance in the opening / closing operation.

The link cover 20a has a gear portion 26a provided at one end of the upper and lower links 23A and 23B.
Since 26b is surrounded from both sides, adhesion of dust to the gear portion is suppressed, and a smooth operation can be obtained for a long period of time.

Although the front suction port 3 is opened and closed by the movable panel 6 supported by the opening / closing drive mechanism 5 in the above embodiment, the invention is not limited to this, and the upper suction port 2 is not limited thereto. It may be applied to a movable panel that can be opened and closed and an opening and closing drive mechanism.

[0091]

As described above, according to the present invention, the panel is provided with an opening / closing drive mechanism that requires a small space, and the suction port can be opened and closed freely. It is effective in preventing dust from entering the inside of the main body during use and maintaining cleaning.
