Detailed Description
Fig. 1 is a schematic structural view of an air conditioner indoor unit 10 according to an embodiment of the present invention. The air conditioner indoor unit 10 may be of any type, such as a floor type or a wall-mounted type, and fig. 1 is only an example of a wall-mounted type, and the air conditioner indoor unit 10 should not be construed as being limited to a wall-mounted type.
The air conditioner indoor unit 10 may generally include a cabinet 100 and an airflow adjusting device 200. The air flow adjusting device 200 may be disposed in the casing 100 and configured to provide indoor air or outdoor air for mixing with the heat exchange air to the air outlet 120 of the air conditioner indoor unit 10, and further configured to provide outdoor air to the air inlet of the air conditioner indoor unit 10, which sequentially flows through the air inlet and the heat exchange air duct 110 to generate heat exchange air.
The cabinet 100 may be provided with an air outlet 120 for allowing heat-exchanged air generated by the indoor unit 10 of the air conditioner to be discharged to the indoor space, thereby adjusting the temperature of the indoor space. In this embodiment, the air conditioner indoor unit 10 may further include a heat exchanger disposed in the heat exchange air duct 110 for exchanging heat with air flowing through the heat exchange air duct, so as to generate heat exchange air.
Fig. 2 is a schematic block diagram of an air flow adjusting device 200 of an air conditioner indoor unit 10 according to an embodiment of the present invention, and fig. 3 is another schematic block diagram of the air flow adjusting device 200 of the air conditioner indoor unit 10 shown in fig. 2.
The air flow adjusting device 200 is formed with a first air flow outlet 241 facing the outlet port 120, an indoor air flow inlet 245 for letting in indoor air, and an outdoor air flow inlet 246 for letting in outdoor air. That is, indoor air may enter the interior of the airflow regulating device 200 (e.g., the conditioned space 248 of the airflow regulating device 200) via the indoor airflow inlet 245, and outdoor air may enter the interior of the airflow regulating device 200 via the outdoor airflow inlet 246. Since the first airflow outlet 241 faces the air outlet 120, the indoor air or the outdoor air flowing out of the airflow adjusting device 200 through the first airflow outlet 241 can be mixed with the heat exchange air near the air outlet 120, thereby achieving a mixed flow or mixed wind effect. The curved arrows in fig. 1 show the flow path of the indoor air or the outdoor air flowing out of the airflow adjusting device 200 from the first airflow outlet 241, and the straight arrows show the flow path of the mixed airflow flowing out of the cabinet 100 from the outlet 120. In this embodiment, the mixing process may be performed before the heat-exchanging air flows out of the air outlet 120.
Fig. 4 is a schematic block diagram of an air flow adjusting device 200 of an air conditioner indoor unit 10 according to an embodiment of the present invention, fig. 5 is another schematic block diagram of the air flow adjusting device 200 of the air conditioner indoor unit 10 shown in fig. 4, and fig. 6 is still another schematic block diagram of the air flow adjusting device 200 of the air conditioner indoor unit 10 shown in fig. 4, in which an air flow path is shown in an arrow direction.
The air flow adjusting device 200 further has an adjusting part for controllably communicating the first air flow outlet 241 with the indoor air flow inlet 245 to allow indoor air to flow to the outlet vent 120 through the first air flow outlet 241, or communicating the first air flow outlet 241 with the outdoor air flow inlet 246 to allow outdoor air to flow to the outlet vent 120 through the first air flow outlet 241. That is, the adjusting part may separately communicate the first air flow outlet 241 with the indoor air flow inlet 245 to mix the heat exchange air with the indoor air (as shown in fig. 4), and separately communicate the first air flow outlet 241 with the outdoor air flow inlet 246 to mix the heat exchange air with the outdoor air (as shown in fig. 5).
In some embodiments, the regulating portion may also simultaneously communicate the first airflow outlet 241 with the indoor airflow inlet 245 and the first airflow outlet 241 with the outdoor airflow inlet 246 (as shown in fig. 6), thereby simultaneously mixing the heat exchange air with the indoor air and the outdoor air. Because the indoor air and the outdoor air can be simultaneously utilized to mix with the heat exchange air, the air flow for mixing is further improved, and the mixing effect is improved. The indoor air can be natural air, and the outdoor air can be fresh air.
When natural air is mixed with the heat exchange air, the temperature of the heat exchange air flowing out of the air outlet 120 can be properly increased to prevent the heat exchange air with lower temperature from causing cold of the user. When fresh air and heat exchange air are mixed, the temperature of the heat exchange air flow flowing out of the air outlet 120 can be properly increased, fresh outdoor air can be provided for indoor air, and the air conditioner has the advantages of improving air supply comfort and preventing a user from generating air conditioning diseases.
The controlled communication between the first airflow outlet 241 and the indoor airflow inlet 245 by the adjusting portion can cause the airflow adjusting device 200 to form a natural airflow channel for circulating natural air from the indoor space, so that the indoor air can flow to the vicinity of the outlet 120 through the indoor airflow inlet 245, the natural airflow channel, and the first airflow outlet 241 in sequence.
The first air outlet 241 and the outdoor air inlet 246 are connected in a controlled manner by the adjusting portion, so that a fresh air flow channel for circulating fresh air from the outdoor space is formed inside the air flow adjusting device 200, and the fresh air flow channel is connected to the first air outlet 241 and the outdoor air inlet 246, so that the outdoor air can flow to the vicinity of the air outlet 120 through the outdoor air inlet 246, the fresh air flow channel and the first air outlet 241 in sequence.
In some embodiments, the controlled communication between the first air flow outlet 241 and the outdoor air flow inlet 246 and the indoor air flow inlet 245 by the adjusting portion may cause the air flow adjusting device 200 to form an indoor air flow channel for circulating indoor air from the indoor space and a fresh air flow channel for circulating fresh air from the outdoor space at the same time, so that the indoor air and the outdoor air may simultaneously flow to the vicinity of the air outlet 120 through the first air flow outlet 241.
The air conditioner indoor unit 10 of this embodiment, owing to add the air current adjusting device 200 of specific structure, regulate and control through the regulating part to air current adjusting device 200, can make indoor air or outdoor air carry to air outlet 120 via first air current export 241, and then make indoor air or outdoor air can mix with the heat transfer air that flows to air outlet 120, the heat transfer air current after mixing can blow to the indoor space via air outlet 120, this makes the air conditioner indoor unit 10 of this embodiment can utilize the structure of retrenching to improve user's travelling comfort, reduce or avoid air conditioning process to cause user's air conditioner illness or cold.
In some embodiments, the housing 100 may further have an air inlet (not shown). The inside of the casing 100 is formed with a heat exchange air duct 110 between the air inlet and the air outlet 120, and an air flow adjusting area 150 at one side of the heat exchange air duct 110. The air inlet is used to allow indoor air to flow into the heat exchange air duct 110 in the cabinet 100 to exchange heat with a heat exchanger in the heat exchange air duct 110, thereby generating heat exchange air.
The intake vent may be located at the top of the enclosure 100, for example, may be located on the top panel of the enclosure 100. The air outlet 120 may be located at the bottom of the front side of the casing 100, for example, may be located at the bottom of the front panel of the casing 100. The air flow conditioning region 150 may be located on one lateral side of the heat exchange air duct 110. The directional terms such as "top", "lateral", "front" and the like are relative to the actual usage state of the air conditioner indoor unit 10.
Through carrying out special arrangement to the position of air intake, air outlet 120 and air current regulation district 150, both can make the air current adjusting device 200 in the air current regulation district 150 carry the air current to air outlet 120, can make air current adjusting device 200 carry the air current to the air intake again, possess simple structure, air current transport mode nimble various advantage.
The flow conditioning device 200 is disposed within the flow conditioning region 150. Since the air flow adjusting region 150 is formed inside the casing 100, the air flow adjusting device 200 is disposed in the air flow adjusting region 150, and the air flow adjusting device 200 has the function of guiding indoor natural air and outdoor fresh air at the same time, which is beneficial to improving the structural integrity of the air conditioner indoor unit 10, thereby facilitating the simplification of the assembling process of the air conditioner indoor unit 10.
In some embodiments, the airflow conditioning device 200 further defines a second airflow outlet 242 adjacent to the intake vent, and the conditioning portion is further configured to controllably communicate the second airflow outlet 242 with the outdoor airflow inlet 246 to allow outdoor air to flow to the intake vent via the second airflow outlet 242.
The second airflow outlet 242 and the outdoor airflow inlet 246 are controllably communicated by the adjusting portion, so that another fresh airflow channel which is communicated with the second airflow outlet 242 and the outdoor airflow inlet 246 and used for circulating fresh air from an outdoor space is formed inside the airflow adjusting device 200, the outdoor air can sequentially flow through the outdoor airflow inlet 246, the fresh airflow channel and the second airflow outlet 242 to flow to the vicinity of the air inlet, the outdoor air flowing out of the second airflow outlet 242 can enter the heat exchange air duct 110 through the air inlet and exchange heat with the heat exchanger, so as to form heat exchange air, which can improve the freshness of the heat exchange air, and solve the problem of air conditioning diseases caused by the airtight indoor space.
The gas flow regulating device 200 further comprises a housing portion 240, which housing portion 240 may form a housing of the gas flow regulating device 200. The indoor air flow inlet 245, the outdoor air flow inlet 246, the first air flow outlet 241 and the second air flow outlet 242 may all be opened on the housing part 240, which may simplify the structure of the air flow adjusting device 200.
The first air flow outlet 241 may be located at the bottom of the case part 240 and inside the outlet port 120, so that indoor air or outdoor air flowing out of the first air flow outlet 241 may be smoothly mixed with heat exchange air before flowing out of the outlet port 120. The inner side of the air outlet 120 may be a boundary between the heat exchanging air duct 110 and the air outlet 120.
The second airflow outlet 242 may be located at the top of the casing 240, which is beneficial to shorten the distance between the second airflow outlet 242 and the air inlet, and increase the flow rate of fresh air flowing into the heat exchange air duct 110 through the air inlet.
The housing portion 240 is removably embedded within the airflow moderating zone 150. When the airflow adjusting device 200 fails, the airflow adjusting device 200 can be simply and conveniently detached integrally, which is beneficial to reducing the difficulty in repairing the airflow adjusting device 200.
The housing portion 240 is formed with a conditioning space 248 inside. The adjusting part may be provided to the adjusting space 248 and serves to communicate the first air flow outlet 241 with the indoor air flow inlet 245 and the outdoor air flow inlet 246 or communicate the second air flow outlet 242 with the outdoor air flow inlet 246 by controllably opening and closing the indoor air flow inlet 245, the outdoor air flow inlet 246, the first air flow outlet 241, and the second air flow outlet 242.
For example, when the adjusting part opens the first air flow outlet 241 and the indoor air flow inlet 245 (as shown in fig. 4), the indoor air may flow into the adjusting space 248 through the indoor air flow inlet 245 and then flow out of the adjusting space 248 through the first air flow outlet 241. When the adjusting part opens the first air flow outlet 241 and the outdoor air flow inlet 246 (as shown in fig. 5), the outdoor air may flow into the adjusting space 248 through the outdoor air flow inlet 246 and then flow out of the adjusting space 248 through the first air flow outlet 241. When the conditioning part opens the first air flow outlet 241 and the indoor air flow inlet 245 and the outdoor air flow inlet 246 (as shown in fig. 6), indoor air may flow into the conditioned space 248 through the indoor air flow inlet 245, outdoor air may flow into the conditioned space 248 through the outdoor air flow inlet 246, and indoor air and outdoor air flowing into the conditioned space 248 may flow out of the conditioned space 248 through the first air flow outlet 241. When the conditioner opens the second airflow outlet 242 and the outdoor airflow inlet 246, the outdoor air may flow into the conditioned space 248 through the outdoor airflow inlet 246 and then flow out of the conditioned space 248 through the second airflow outlet 242.
The regulating portion may include a rotary member 222 and two controllable dampers 224.
The rotating member 222 is controlled to be rotatably disposed between the indoor airflow inlet 245 and the outdoor airflow inlet 246 to open and close the indoor airflow inlet 245 and the outdoor airflow inlet 246.
The two controllable dampers 224 are respectively provided in one-to-one correspondence with the first airflow outlet 241 and the second airflow outlet 242 to open and close the first airflow outlet 241 and the second airflow outlet 242.
In some embodiments, the adjustment portion may further include a driving mechanism, such as a stepper motor 280, for driving the rotation member 222 to rotate. The root of the rotation member 222 may be connected to the driving mechanism, and the head of the rotation member 222 is used to open and close the indoor airflow inlet 245 and the outdoor airflow inlet 246. For example, the head of the rotation member 222 may be adapted to the shape of the indoor airflow inlet 245 and the outdoor airflow inlet 246, the indoor airflow inlet 245 may be closed when the head of the rotation member 222 rotates to the indoor airflow inlet 245, and the indoor airflow inlet 245 may be opened when the head of the rotation member 222 moves away from the indoor airflow inlet 245. The outdoor airflow inlet 246 may be closed when the head of the rotation member 222 is rotated to the outdoor airflow inlet 246, and the outdoor airflow inlet 246 may be opened when the head of the rotation member 222 is moved away from the outdoor airflow inlet 246.
In some embodiments, the outdoor airflow inlet 246 may communicate with the outdoor space through a fresh air duct.
The rotation member 222 simultaneously controls the opening and closing of the indoor airflow inlet 245 and the outdoor airflow inlet 246, thereby simplifying the structure of the adjustment unit and simplifying the logic of opening and closing the indoor airflow inlet 245 and the outdoor airflow inlet 246. In alternative embodiments, the rotary member 222 may be replaced with a controllable damper 224. Each of the controllable dampers 224 may be provided with a driving mechanism, such as a stepping motor 280, for opening and closing the first and second airflow outlets 241 and 242.
For example, when the air conditioner indoor unit 10 receives a command for mixing air with indoor air, the adjusting part may drive the head of the rotating member 222 away from the indoor airflow inlet 245 to open the indoor airflow inlet 245 (at this time, the head of the rotating member 222 may close the outdoor airflow inlet 246, as shown in fig. 4), and drive the controllable damper 224 corresponding to the first airflow outlet 241 to open the first airflow outlet 241. When the indoor unit 10 of the air conditioner receives the command for mixing air with outdoor air, the adjusting part may drive the head of the rotating member 222 away from the outdoor air inlet 246 to open the outdoor air inlet 246 (at this time, the head of the rotating member 222 may close the indoor air inlet 245, as shown in fig. 5), and drive the controllable damper 224 corresponding to the first air outlet 241 to open the first air outlet 241. When the indoor unit 10 receives a command to mix air with indoor air and outdoor air, the adjusting part may drive the head of the rotating member 222 to rotate between the outdoor air inlet 246 and the indoor air inlet 245 (as shown in fig. 6), and drive the controllable damper 224 corresponding to the first air outlet 241 to open the first air outlet 241. When the air conditioner indoor unit 10 receives a command for ventilating air with outdoor air, the adjusting portion may drive the head of the rotating member 222 away from the outdoor airflow inlet 246 to open the outdoor airflow inlet 246, and drive the controllable damper 224 corresponding to the second airflow outlet 242 to open the second airflow outlet 242.
The respective instructions may be sent to the air conditioner 10 by a user when the air conditioner 10 performs a cooling function or a heating function (preferably, a cooling function).
The airflow adjusting apparatus 200 may further include an adjusting fan 260 disposed in the adjusting space 248 for inducing an airflow flowing from the indoor airflow inlet 245 or the outdoor airflow inlet 246 to the first airflow outlet 241 or the second airflow outlet 242. The indoor air inflow port 245 and the outdoor air inflow port 246 may be adjacently disposed and respectively opposite to the suction port of the adjusting fan 260, and the air outlet 120 of the adjusting fan 260 may be opposite to the first air outflow port 241 and the second air outflow port 242. For example, the conditioning fan 260 may be one or more centrifugal fans.
Since the air flow adjusting device 200 has the adjusting fan 260 disposed in the adjusting space 248, the adjusting fan 260 can promote the formation of the air flow flowing from the indoor air inlet 245 or the outdoor air inlet 246 to the first air outlet 241 or the second air outlet 242, which is beneficial to improve the delivery activity of the indoor air or the outdoor air, improve the air flow delivery efficiency, and thus improve the activity of the air mixing process of the air conditioner indoor unit 10. The adjusting fan 260 may be controlled to be activated after the respective components of the adjusting portion reach the designated positions.
Compared with the technical scheme of additionally installing a specific drainage mechanism and utilizing the wind pressure difference to convey natural air to the air outlet so as to mix the natural air with the heat exchange air, the air conditioner indoor unit 10 of the embodiment can actively convey indoor air and outdoor air for mixing air to the air outlet 120, so that the air flow for mixing air is relatively large, and the air conditioner indoor unit has a better air mixing effect.
The indoor unit 10 may further include a heat exchange fan disposed in the heat exchange air duct 110 for inducing the formation of heat exchange air flowing from the air inlet into the heat exchange air duct 110 and flowing out of the air outlet 120 after flowing through the heat exchanger. The heat exchange fan may be a cross flow fan. The heat exchange fan may be controlled to be turned on when the air conditioner indoor unit 10 performs a cooling function or a heating function.
The control flow of the air conditioner indoor unit 10 will be further described below by taking the air conditioner indoor unit performing the cooling function as an example. After the indoor unit 10 of the air conditioner receives the instruction of starting refrigeration, the heat exchange fan is controlled to be started. Under the action of the heat exchange fan, air near the air inlet flows through the air inlet and the heat exchange air duct 110 in sequence to form heat exchange air, and flows into the indoor space from the air outlet 120. When the air conditioner indoor unit 10 receives a command for mixing air with indoor air, the adjusting part drives the head of the rotating member 222 away from the indoor airflow inlet 245 to open the indoor airflow inlet 245, and the adjusting fan 260 is controlled to be turned on. Under the action of the adjusting fan 260, the indoor air flows through the indoor airflow inlet 245, the indoor airflow channel and the first airflow outlet 241 in sequence, then flows to the vicinity of the air outlet 120, and is mixed with the heat exchange air flowing to the air outlet 120, and the mixed airflow is discharged into the indoor space through the air outlet 120.
In the air conditioner indoor unit 10 of the present invention, since the air flow adjusting device 200 having a specific structure is additionally provided, by adjusting and controlling the adjusting part of the air flow adjusting device 200, indoor air or outdoor air can be conveyed to the air outlet 120 through the first air flow outlet 241, so that the indoor air or the outdoor air can be mixed with the heat exchange air flowing to the air outlet 120, and the mixed heat exchange air can be blown to the indoor space through the air outlet 120, such that the air conditioner indoor unit 10 of the present invention can improve user comfort by using a simplified structure, and reduce or avoid air conditioning diseases or colds of users caused by the air conditioning process.
