Description
Technical Field
The present invention relates to an air conditioner. In particular, the present invention relates to an air conditioner with louvers for regulating the output airflow.
Background
Air conditioning is a common expression for conditioning air to a desired state. It can heat air during cold periods, cool air during warmer periods, or be used to purify air if the air contains undesirable particles. However, the expression air conditioning is most often used when emphasis is given to cooling. As a product, air conditioners may look and be used in various forms and in various ways, but they all share the same basic technology. The air conditioner includes a compressor, a condenser, an evaporator, and generally an expansion device.
There are different types of air conditioners. One type of air conditioner may be referred to as a split air-conditioner. In a split type air conditioner, a condenser and an evaporator are located in two different separate units, which are connected to each other via pipes to circulate refrigerant from one unit to the other.
Another type of Air Conditioner may be referred to as a Packaged Air Conditioner. An integrated Air Conditioner (AC) may be said to be a self-contained type of system in which all cooling cycle components, such as the compressor, condenser, expansion device, evaporator, and control system, are enclosed in a single package.
In any case, what is ultimately output from the air conditioner is conditioned air that is blown to a room or some other space. It is typically desirable that air be delivered in sufficient quantities at low noise, and it is also desirable that the air delivery process should be energy efficient.
In order to guide air into a room, so-called louvers may be used at an air outlet of the air conditioner. Thus, the louver may be described as a movable element arranged to displace air blown by a fan of the air conditioner. One or more such movable elements or louvers may be provided at the air outlet. The louver(s) may deflect the airflow and aim the airflow in a particular direction.
Louvers are particularly important in air conditioning/heat pump units because louvers can deliver conditioned air in different directions. Therefore, the performance of the air conditioner and the comfort of the user can be improved. According to some embodiments, one horizontal louver that can be adjusted (automatically or manually) to direct air up and down is combined with a number of vertical louvers that can be adjusted (automatically or manually) to direct air sideways. This will allow 3-dimensional air guidance. Air conditioner/heat pump manufacturers.
There is a continuing desire for improvements in air conditioners. Accordingly, there is a need for an improved air conditioner.

Detailed Description
The present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which certain embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided by way of example so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. For example, the same or similar components of different embodiments may be interchanged between different embodiments. For example, the louvers as described herein are shown mounted on an indoor unit of a split air conditioner, but the louvers may equally be mounted on any type of air conditioner. Some components may be omitted in different embodiments. Also, some components typically used in air conditioners have been omitted to more clearly illustrate the invention. Like numbers refer to like elements throughout.
In fig. 1, a cross-sectional view of an air conditioner 10 is depicted. The air conditioner 10 in fig. 1 is an indoor unit of a split type air conditioner, but the air conditioner 10 may be any type of air conditioner. The air conditioner 10 includes a frame 12 that houses components of the air conditioner. The air conditioner includes a fan 14 configured to blow air out of the air conditioner 10 via an air outlet 16. The air outlet 16 is provided with louvers 20. The shutter 20 may be moved using a displacement mechanism 22.
In fig. 1, the louver 20 is positioned at a downward position in which the air blown by the fan 14 is directed downward. This position of the louvers 20 may typically be used to distribute heated air into a room.
The displacement mechanism 22 according to one embodiment may include a first pin 24 fixedly mounted relative to the frame 12 of the air conditioner 10. Likewise, a second pin 26 is provided. The displacement mechanism 22 further includes a first shutter link 28 for holding the shutter 20. The shutter link 28 includes a slot 30 arranged to receive the second pin 26. Likewise, a first crank 32 is provided. The first end 31 of the first crank may be connected to the first pin 24 and the second end 33 may be connected to the first louver link 28. According to some embodiments, the shutter 20 may be made integral with the shutter link 28. In some embodiments, the shutter 20 includes a plurality of vanes 36, 38. In the embodiment shown in fig. 1, two vanes are provided, a first vane 36 and a second vane 38. However, it is also contemplated that more than two blades or a single blade 36 may be provided.
When in use, the shutter 20 may be moved between different positions using the displacement mechanism 22. This allows a wide range of movement of the air guiding louver 20 and thus air guiding possibilities. Due to the configuration of the displacement mechanisms 22, the adjustment range of the blind 20 can be wider than conventional blinds by using only one displacement mechanism 22. The displacement mechanism 22 has only one degree of freedom, so that the blind can be manoeuvred into a wide range of positions using only a single motor or using one handle when the blind is manually adjusted.
The displacement mechanism 22 may advantageously be made planar, and in some embodiments may include only two free binary links, one grounded base link, two rotational joints, and one pin and slot joint. One of the free links may be rigidly connected to the louver 20 as a louver link 28 and connected to the fixed base link by a rotational joint or by a pin and slot joint. The other free link, i.e., the crank 32, has a grounded rotary joint that may or may not be coupled to an actuator, such as a motor.
The shutter link 28 and the crank 32 may be connected to each other by, for example, a moving rotary joint or by a pin and slot joint providing one degree of freedom.
In fig. 2, the louver 20 of the air conditioner 10 is positioned at an upward position in which the air blown by the fan 14 is directed upward. This position of the louvers 20 may typically be used to distribute cooled air into the room.
As can be seen, the angular displacement between the different positions of fig. 1 and 2 can be made very large by moving in only one dimension of the displacement mechanism 22, such as using only one motor. The displacement mechanism 22 described herein allows for a combination of rotational and displacement movement, which can change the angle of the louvers by 120 degrees without reducing the area of the air outlet in extreme positions.
Additionally, any angular displacement between the outermost positions of fig. 1 and 2 may also position the louvers 20 therein. In fig. 3, the shutter 20 is placed in a neutral intermediate position.
In fig. 4, a second embodiment of the displacement mechanism 22 is depicted. In the embodiment of fig. 4, the second pin 26 is mounted on the first crank 32. Likewise, the first louver link 28 may rotate about a joint 39 that is fixed relative to the frame 12 of the air conditioner 10.
To make the displacement of the blind 20 more robust, and to better support the blind 20, a plurality of displacement mechanisms 22 may be provided along the length of the blind. For example, two or three displacement mechanisms 22 may be provided. According to some embodiments, at least two displacement mechanisms 22 and 22a are provided as shown in fig. 5, i.e. one at each end of the shutter 20. In fig. 5, an embodiment of a configuration having one displacement mechanism 22 at each end of the shutter 20 is depicted. Thus, the first displacement mechanism 22 is disposed at one end of the louver 20, and the second displacement mechanism 22a is disposed at the other (second) end of the louver 20. When the second displacement mechanism 22a is provided, the second displacement mechanism will be provided with elements corresponding to or identical to those of the first displacement mechanism 22. Thus, according to one embodiment, the second displacement mechanism 22a may include a third pin fixedly mounted with respect to the frame of the air conditioner, and a fourth pin. Also, a second louver link may be provided for holding the louver. The second shutter link includes a slot arranged to receive the fourth pin. A first end of the second crank is connected to the third pin and a second end is connected to the second shutter link.
In the embodiment of fig. 5, the displacement according to the first embodiment is depicted, but any type of displacement mechanism may be used. For example, two displacement mechanisms according to the embodiment of fig. 4 may be used instead.
In fig. 6, an embodiment is depicted in which the displacement mechanism 22 is driven by a motor 40. Advantageously, the motor 40 may be arranged to drive the pin 12. According to another embodiment, the first pin 24 may be rotatable and drive the displacement mechanism 22. However, the motor 40 may also be arranged to drive another part of the displacement mechanism 22.
