Referring to fig. 1 to 5, in some embodiments of the indoor unit air-out control device provided by the present invention, the control device includes a casing 10, a determining device and an adjusting device, the casing 10 is provided with a plurality of air outlets 20, each air outlet 20 corresponds to one adjusting area 50, the determining device is used for determining whether there is an adjusting requirement in the adjusting area 50 corresponding to the air outlet 20, the adjusting device is in signal connection with the determining device, and the adjusting device is configured to adjust an air-out direction of the air outlet 20 according to a determination result of the determining device.
In the above embodiment, the indoor unit air-out control device includes the casing 10, the judging device and the adjusting device, the casing 10 is provided with the plurality of air outlets 20, and each air outlet 20 corresponds to one adjusting area 50, that is, the adjusting areas 50 are divided according to the number of the air outlets 20, so as to realize the temperature control in areas, and provide a basis for taking different temperature control measures in areas.
In the above embodiment, the determining device may determine whether there is an adjusting requirement in the adjusting region 50, and the adjusting device may adjust the air outlet direction of the air outlet 20 according to the determination result of the determining device, so that the air outlet direction of the air outlet 20 is different between when there is an adjusting requirement and when there is no adjusting requirement. For example, when there is an adjustment requirement, the adjustment requirement is satisfied as a primary objective when the air outlet direction is adjusted, and energy saving is not required as a primary objective; when there is no adjustment requirement, energy saving is the primary objective when adjusting the air outlet direction, for example, the air outlet direction of the air outlet 20 can be adjusted to a position where energy is saved, thereby reducing energy waste and meeting the energy saving requirement.
In some embodiments, each conditioning region 50 corresponds to one outlet 20; in other embodiments, each conditioning region 50 can correspond to two or more outlets 20.
When the adjustment area 50 is divided, the determination may be performed according to a distance from the outlet 20, for example, if a distance between a certain adjustment area 50 and the first outlet 21 is the closest, the adjustment area is divided into a first adjustment area 51 corresponding to the first outlet 21, and the adjustment device adjusts the air outlet direction of the first outlet 21 according to a determination result of the determination device on the first adjustment area 51.
In some embodiments, the adjusting device comprises a wind deflector 30, and the wind deflector 30 is movably disposed at the wind outlet 20. The air deflector 30 is arranged to guide the air flow, and the air outlet direction of the air outlet 20 can be adjusted by adjusting the position of the air deflector 30 relative to the casing 10.
As shown in fig. 5, the air deflector 30 is a flat plate structure, the air deflector 30 is disposed at the air outlet 20, and the air deflector 30 can guide the outflow direction of the airflow.
In some embodiments, the air deflector 30 is rotatably mounted at the outlet 20. When the air outlet direction of the air outlet 20 needs to be adjusted, the air guide plate 30 may be driven to rotate relative to the housing 10.
In some embodiments, the housing 10 is provided with a return air opening 40, the adjustment device being configured to: when the judging device judges that the adjusting area 50 has the adjusting requirement, the air outlet direction of the air outlet 20 corresponding to the adjusting area 50 is adjusted to a position where the air quantity of the air outlet flow flowing to the adjusting area 50 is larger than the air quantity flowing to the air return port 40; and when the judging device judges that there is no adjusting demand in the adjusting region 50, the air outlet direction of the air outlet 20 corresponding to the adjusting region 50 is adjusted to a position where the air volume of the air outlet flow flowing to the air return port 40 is larger than the air volume flowing to the adjusting region 50.
The air flow coming out from the outlet 20, whether or not it is involved in the temperature regulation of the conditioning area 50, will eventually return to the indoor unit through the return air inlet 40, substantially achieving its circulation.
When the determining device determines that there is a demand for adjustment in the adjustment area 50, the air outlet direction of the air outlet 20 corresponding to the adjustment area 50 is adjusted to a position where the amount of air flowing into the adjustment area 50 is greater than the amount of air flowing into the return air inlet 40. In this way, the airflow flowing out of the air outlet 20 flows more to the adjustment area 50, so as to achieve the purpose of controlling the temperature of the adjustment area 50.
When the determining device determines that there is no adjustment demand in the adjustment region 50, the air outlet direction of the air outlet 20 corresponding to the adjustment region 50 is adjusted to a position where the air volume of the outlet airflow flowing to the return air inlet 40 is greater than the air volume flowing to the adjustment region 50. Therefore, the airflow flowing out of the air outlet 20 flows to the air return opening more, and the flow of the outlet airflow entering the adjusting area 50 for heat exchange is reduced, so that the airflow flowing back through the air return opening 40 can retain more energy, the energy consumption is finally reduced, and the purpose of energy saving is achieved.
As shown in fig. 1 to 4, in some embodiments, the air return opening 40 and the plurality of air outlet openings 20 are disposed on the same side of the casing 10, and the plurality of air outlet openings 20 are arranged along the circumferential direction of the air return opening 40.
The air outlets 20 are all disposed on the same side of the casing 10, so that the air outlets 20 can respectively face a space located on one side of the casing 10, and temperature control of the plurality of adjustment areas 50 in the space is achieved. The air return opening 40 and the air outlets 20 are arranged on the same side face of the casing 10, and after the casing 10 is installed in the space, the air return opening 40 can have a larger flow area, the air flow circulation speed is increased, and the temperature regulation efficiency is further improved.
In other embodiments, the air return opening 40 and the air outlets 20 may also be disposed on different sides of the housing 10. Other options for the location of the outlet 20 relative to the return air inlet 40 are possible.
As shown in fig. 5, in some embodiments, the air outlets 20 include a first air outlet 21, the first air outlet 21 corresponds to a first adjusting area 51, and the adjusting device is configured to adjust the air outlet direction of the first air outlet 21 to a first included angle β 1 between the first air outlet and the first direction, which is a direction from the air return opening 40 to the first air outlet 21, of not less than 55 ° or not less than 65 ° when the determining device determines that there is no adjustment requirement in the first adjusting area 51.
As shown in fig. 6a and 6b, are simulated graphs of the air flow velocity at the first included angle β 1 of 55 ° and 65 °, respectively. As can be seen from comparison of the two figures, when the first included angle β 1 is greater than or equal to 55 °, the airflow flowing out from the first air outlet 21 flows more to the air return opening 40, and at this time, more airflow does not undergo a process of heat exchange with the air in the adjustment area 50, so that the energy of the airflow flowing back to the air return opening 40 can be increased, thereby achieving the purpose of saving energy.
In some embodiments, the plurality of outlets 20 include a first outlet 21 and a second outlet 22, the first outlet 21 corresponds to the first adjusting region 51, the second outlet 22 corresponds to the second adjusting region 52, when the determining device determines that the first adjusting region 51 has no adjusting requirement and the second adjusting region 52 has an adjusting requirement, the adjusting device is configured to adjust the air outlet direction of the first outlet 21 to a first included angle β 1 and adjust the air outlet direction of the second outlet 22 to a second included angle β 2, the first included angle β 1 is at least 5 degrees larger than the second included angle β 2, the first included angle β 1 is an included angle between the air outlet direction of the first outlet 21 and the first direction, the second included angle β 2 is an included angle between the air outlet direction of the second outlet 22 and the second direction, the first direction is a direction from the return air inlet 40 to the first outlet 21, and the second direction is a direction from the return air inlet 40 to the second outlet 22.
Since the position of each outlet 20 relative to the return air inlet 40 is different, the direction from the return air inlet 40 to each outlet 20 is different for each outlet 20. As shown in fig. 5, the first direction is a direction indicated by a dotted line a, and the direction is directed from the air return opening 40 to the first air outlet 21; the second direction is a direction indicated by a dotted line b in the figure, and the direction is directed from the air return opening 40 to the second air outlet 22.
As can be seen from fig. 5, when the indoor unit air-out control device is in operation, and the adjustment requirements of each adjustment area 50 are different, the air-out directions of the corresponding air outlets 20 are also different, so that adjustment as required can be realized, and further, energy consumption is reduced and energy is saved when no adjustment requirement is met.
In some embodiments, the indoor unit air outlet control device further includes a control panel, the determining device is in signal connection with the control panel, and the determining device is configured to determine whether the adjusting area 50 has an adjusting requirement according to an input signal received by the control panel.
In this embodiment, the determination means determines whether there is a need for adjustment of the adjustment area 50 based on input information from the operator on the control panel. For example, the operator may directly input whether there is a regulation demand in the regulation area 50 on the control panel, or may input other intermediate information, and the determination device further determines whether there is a regulation demand according to the intermediate information.
The advantage of judging whether the regulation requirement exists or not according to the input information of the control panel is that the regulation requirement-free state can be still selected when people exist or the regulation requirement is still selected when no people exist.
In some embodiments, the indoor unit outlet air control device further includes a sensor 60, and the determining device is in signal connection with the sensor 60, and configured to determine whether the regulation area 50 is occupied according to the detection result of the sensor 60, and output a signal of regulation requirement when the regulation area 50 is occupied, and output a signal of no regulation requirement when the regulation area 50 is not occupied.
As shown in fig. 4, a sensor 60 is provided on the housing 10, and the presence of a person in the adjustment area 50 can be detected by the sensor 60.
The sensor 60 may be an infrared sensor that determines whether a person is present by detecting whether a portion having a temperature greater than the ambient temperature is present in the conditioned area 50. For example, in one embodiment, when the ambient temperature is greater than or equal to 6 ℃ and less than or equal to 30 ℃ and the temperature of the suspected area is greater than the ambient temperature by 2 ℃, the suspected area is determined to be a human body.
In some embodiments, the indoor unit air outlet control device may also include a camera device, and the determining device is in signal connection with the camera device and determines whether there is a person in the adjusting area 50 by reading information in an image captured by the camera device.
The structure and working process of an embodiment of the air outlet control device of the indoor unit of the present invention are explained as follows:
