Hereinafter, an air conditioner 100 according to an embodiment of the first aspect of the present invention will be described with reference to the accompanying drawings.
As shown in fig. 1 and 2, the air conditioner 100 has a first air inlet 100a and a second air inlet 100b, and external air may flow into the air conditioner 100 through the first air inlet 100a and the second air inlet 100b, respectively. It is understood that the first air inlet 100a and the second air inlet 100b may be disposed at intervals, or may be disposed at non-intervals, and the first air inlet 100a and the second air inlet 100b may be in communication with each other.
The air conditioner 100 includes a casing 1 and a heat exchanger 2, the casing 1 includes a fixed casing 11 and a movable casing 12, a first air inlet 100a is formed on the fixed casing 11, the movable casing 12 is movable relative to the fixed casing 11, when the movable casing 12 is located at a predetermined position, the movable casing 12 closes a second air inlet 100b, at this time, external air cannot flow into the casing 1 through the second air inlet 100b, when the movable casing 12 leaves at a predetermined position, the movable casing 12 opens the second air inlet 100b, at this time, external air can flow into the casing 1 through the second air inlet 100 b. The heat exchanger 2 is disposed in the housing 1 to exchange heat with the air flowing into the housing 1, and then the air flows into the housing 1 through the first air inlet 100a to exchange heat with the heat exchanger 2, and/or the air flows into the housing 1 through the second air inlet 100b to exchange heat with the heat exchanger 2. For example, in the example of fig. 3 and 4, when the air conditioner 100 is operated, if the movable housing 12 is moved to a predetermined position (as shown in fig. 3), external air may flow into the cabinet 1 through the first air inlet 100a to exchange heat with the heat exchanger 2, and if the movable housing 12 is moved away from the predetermined position (as shown in fig. 4), external air may flow into the cabinet 1 through the first air inlet 100a and the second air inlet 100b to exchange heat with the heat exchanger 2, respectively. The second air inlet 100b may be formed on the fixed housing 11, but is not limited thereto.
As shown in fig. 1 and 2, the air conditioner 100 further includes an electric auxiliary heat 3, the electric auxiliary heat 3 is rotatably provided in the casing 1, the electric auxiliary heat 3 can heat air flowing into the casing 1, the electric auxiliary heat 3 has a first windward wall surface 30a and a second windward wall surface 30b, the first windward wall surface 30a and the second windward wall surface 30b each extend along a length direction (e.g., a left-right direction in the drawing) of the electric auxiliary heat 3, and an area of the first windward wall surface 30a is larger than an area of the second windward wall surface 30 b.
As shown in fig. 3 and 4, the air conditioner 100 includes a driving device 4, the driving device 4 includes a first driving device 41, and the first driving device 41 is connected to the movable housing 12 to drive the movable housing 12 to move so that the movable housing 12 opens or closes the second air inlet 100b. The driving device 4 further includes a second driving device 42, where the second driving device 42 is connected to the electric auxiliary heat 3 to drive the electric auxiliary heat 3 to rotate, so that the electric auxiliary heat 3 rotates around an axis extending along a length direction of the electric auxiliary heat 3, and in a rotation process of the electric auxiliary heat 3, positions of the first windward wall surface 30a and the second windward wall surface 30b relative to the first air inlet 100a are changed, so as to adjust a windward area (or a windward area) of the electric auxiliary heat 3.
For example, when the electric auxiliary heat 3 is needed, for example, the air conditioner 100 is in a heating mode and the movable housing 12 is located at a predetermined position to close the second air inlet 100b, if the gear of the air conditioner 100 is higher and the wind speed is higher, the second driving device 42 may drive the electric auxiliary heat 3 to rotate so that the electric auxiliary heat 3 rotates to the first windward wall surface 30a perpendicular to the airflow direction flowing through the electric auxiliary heat 3, since the area of the first windward wall surface 30a is larger than the area of the second windward wall surface 30b, at this time, the contact area between the electric auxiliary heat 3 and the air (i.e. the windward area of the electric auxiliary heat 3) is larger, and it can be understood that the larger the windward area of the electric auxiliary heat 3 is, the air flow is slow, and the contact area and the contact time between the electric auxiliary heat 3 and the air are also longer, which is beneficial for the electric auxiliary heat 3 to sufficiently heat the airflow flowing through the electric auxiliary heat 3, so as to ensure the heating performance of the air conditioner 100; if the gear of the air conditioner 100 is lower, the electric auxiliary heat 3 may not be activated, for example, the electric auxiliary heat 3 may be in a state that the second windward wall surface 30b is perpendicular to the airflow direction flowing through the electric auxiliary heat 3, at this time, the electric auxiliary heat 3 may be ensured to meet the heating amount of the air conditioner 100, and the contact area between the electric auxiliary heat 3 and air may be reduced, so that the blocking effect of the electric auxiliary heat 3 on the air is reduced, and the air output speed of the air conditioner 100 are conveniently ensured.
For another example, when the electric auxiliary heat 3 is needed, for example, the air conditioner 100 is in a heating mode, and the movable housing 12 leaves the predetermined position to open the second air inlet 100b, and at this time, the air inlet of the air conditioner 100 is larger, the second driving device 42 may drive the electric auxiliary heat 3 to rotate, so that the electric auxiliary heat 3 rotates to the first windward wall 30a perpendicular to the air flow direction flowing through the electric auxiliary heat 3, thereby avoiding that the air conditioner 100 cannot meet the heating requirement due to the larger air inlet, and effectively ensuring the heating performance of the air conditioner 100.
For another example, when the electric auxiliary heat 3 is not needed, for example, the air conditioner 100 is in a cooling mode, at this time, the electric auxiliary heat 3 is turned off, and the electric auxiliary heat 3 can be in a state that the second windward wall surface 30b is perpendicular to the air flow direction flowing through the electric auxiliary heat 3, so as to weaken the blocking effect of the electric auxiliary heat 3 on air, effectively solve the wind shielding problem of the electric auxiliary heat 3, and ensure the service performance of the air conditioner 100.
It is to be understood that the rotation control of the electric auxiliary heat 3 is not limited thereto.
Therefore, compared with the mode that the electric auxiliary heat 3 is fixedly arranged in the shell 1 in some technologies, the windward area of the electric auxiliary heat 3 is fixed, so that the refrigeration performance and the heating performance of the air conditioner 100 can not be simultaneously considered; the air conditioner 100 in the application has the first air inlet 100a and the second air inlet 100b for the air current direction in the casing 1 has uncertainty, through setting up movable casing 12 and electricity and assist hot 3, and make first drive arrangement 41 drive movable casing 12 motion, the rotation of second drive arrangement 42 drive electricity assist hot 3, thereby richened the running mode of air conditioner 100, and can be through controlling first drive arrangement 41 and second drive arrangement 42, be convenient for make the electricity assist hot 3 place the running state (including running mode, place gear etc.) and the place phase-match of movable casing 12 of air conditioner 100, in order to give consideration to the multiple running state of air conditioner 100 better, and then guarantee the refrigeration, the heating performance of air conditioner 100.
It will be appreciated that the first windward wall surface 30a and the second windward wall surface 30b may be directly connected, or the first windward wall surface 30a and the second windward wall surface 30b may be disposed at intervals, and at this time, the first windward wall surface 30a and the second windward wall surface 30b may be connected through other wall surfaces of the electric auxiliary heat 3. The first windward wall surface 30a may be a plane or a curved surface, and the second windward wall surface 30b may be a plane or a curved surface.
For example, in the example of fig. 1 to 4, the electric auxiliary heat 3 is PTC electric auxiliary heat, the cross-sectional shape of the electric auxiliary heat 3 is rectangular, the first windward wall surface 30a and the second windward wall surface 30b are each formed in a plane, and the first windward wall surface 30a and the second windward wall surface 30b are disposed adjacently. The air conditioner 100 may be a hanging type air conditioner, and the casing 1 may include a chassis to which the fixing housing 11 is fixedly connected.
In some embodiments, where the movable housing 12 is at least part of the panel 13 of the air conditioner 100, a portion of the panel 13 of the air conditioner 100 may be formed as the movable housing 12, where another portion of the panel 13 may be directly or indirectly connected to the fixed housing 11 such that the other portion of the panel 13 remains relatively stationary with the fixed housing 11; alternatively, as shown in fig. 3 and 4, the entire panel 13 of the air conditioner 100 may be formed as the movable housing 12 in order to simplify the design of the panel 13 and facilitate the installation of the panel 13.

Other constructions and operations of the air conditioner 100 according to the embodiment of the present invention are known to those skilled in the art, and will not be described in detail herein.
Next, a control method of the air conditioner 100 according to the embodiment of the second aspect of the present invention will be described with reference to the accompanying drawings, in which the air conditioner 100 is the air conditioner 100 according to the above-described embodiment of the first aspect of the present invention.
For example, as shown in fig. 10 and 11, the air conditioner 100 has first to M-th stages, and the wind speed of the air conditioner 100 gradually increases from the first to M-th stages. The control method of the air conditioner 100 includes the steps of:
s1: the air conditioner 100 is operated, and the electric auxiliary heat 3 is in an initial state;
s2: judging whether the movable housing 12 is located at a predetermined position or not, and judging whether the air conditioner 100 is in the heating mode or not;
s3: when it is determined in step S2 that the movable housing 12 is located at the predetermined position and the air conditioner 100 is in the heating mode, the electric auxiliary heater 3 is turned on, and it is determined whether the gear of the air conditioner 100 is located between the first gear and the nth gear, if so, the operation P1 is performed: the electric auxiliary heat 3 is maintained in an initial state, and if not, the operation P2 is performed: the electric auxiliary heat 3 is rotated such that the first windward wall 30a is perpendicular to the direction of the air flow through the electric auxiliary heat 3, where N < M.
For example, the control method of the air conditioner 100 may include: s1: the air conditioner 100 is operated, and the electric auxiliary heat 3 is in an initial state; s2: judging whether the movable housing 12 is positioned at a preset position, judging whether the air conditioner 100 is in a heating mode, namely judging whether the movable housing 12 closes the second air inlet 100b, and judging whether the air conditioner 100 is currently used for heating; s3: when the judgment result in step S2 is: when the movable shell 12 is positioned at a preset position and the air conditioner 100 is in a heating mode, the electric auxiliary heat 3 is started, the electric auxiliary heat 3 can heat air flow flowing through the electric auxiliary heat 3 at the moment, whether the gear of the air conditioner 100 is positioned between the first gear and the N-th gear (comprising the first gear and the N-th gear) or not is judged, and if the gear is less than M, the air conditioner 100 runs on a low windshield, and the electric auxiliary heat 3 does not act and still remains in an initial state at the moment, namely, the electric auxiliary heat 3 does not rotate, so that the heating capacity of the air conditioner 100 is met, meanwhile, the electric auxiliary heat 3 does not need to be driven to rotate, the energy consumption is saved, and the cost is reduced; if not, it is indicated that the air conditioner 100 uses a high wind shield or a strong wind shield, and at this time, the electric auxiliary heat 3 rotates to make the first windward wall surface 30a perpendicular to the direction of the air flow flowing through the electric auxiliary heat 3, that is, the electric auxiliary heat 3 rotates to a state that the first windward wall surface 30a is perpendicular to the direction of the air flow flowing through the electric auxiliary heat 3, so that the electric auxiliary heat 3 sufficiently heats the air flow flowing through the electric auxiliary heat 3, thereby ensuring the heating performance of the air conditioner 100 while realizing a larger air output of the air conditioner 100. Wherein M can be a positive integer greater than 1, N < M is greater than or equal to 1, and N can be a positive integer.
Therefore, by reasonably setting the operation state of the electric auxiliary heat 3, the state of the electric auxiliary heat 3 is matched with the operation state (including operation mode, gear and the like) of the air conditioner 100 and the position of the movable shell 12, so that various operation states of the air conditioner 100 are considered better, and the heating performance of the air conditioner 100 is further ensured.
It should be noted that, in the same step, the sequence of each action is not fixed. For example, in step S2, the order of "determine whether the movable housing 12 is located at the predetermined position" and "determine whether the air conditioner 100 is in the heating mode" is not fixed, and it may be determined whether the movable housing 12 is located at the predetermined position and then whether the air conditioner 100 is in the heating mode, or whether the air conditioner 100 is in the heating mode and then whether the movable housing 12 is located at the predetermined position.
Specifically, in step S2, it is first determined whether the movable housing 12 is located at a predetermined position, and then whether the air conditioner 100 is in the heating mode, where the control method of the air conditioner 100 may include: the air conditioner 100 is operated, the electric auxiliary heat 3 is in an initial state, whether the movable housing 12 is located at a predetermined position is judged, if yes, whether the air conditioner 100 is in a heating mode is judged, when the air conditioner 100 is in the heating mode as a result of the judgment, the electric auxiliary heat 3 is turned on, whether the gear of the air conditioner 100 is located at the first gear to the nth gear is judged, and if yes, the operation P1 is executed: the electric auxiliary heat 3 remains in the initial state, and if not, the operation P2 is performed: the electric auxiliary heat 3 rotates so that the first windward wall surface 30a is perpendicular to the direction of the air flow through the electric auxiliary heat 3. Alternatively, in step S2, it is first determined whether the air conditioner 100 is in the heating mode, and then whether the movable housing 12 is located at a predetermined position, and the control method of the air conditioner 100 may include: the air conditioner 100 is operated, the electric auxiliary heat 3 is in an initial state, whether the air conditioner 100 is in a heating mode is judged, if so, whether the movable housing 12 is located at a predetermined position is judged, when the movable housing 12 is located at the predetermined position as a result of the judgment, the electric auxiliary heat 3 is turned on, whether the gear of the air conditioner 100 is located at the first gear to the nth gear is judged, and if so, the operation P1 is executed: the electric auxiliary heat 3 remains in the initial state, and if not, the operation P2 is performed: the electric auxiliary heat 3 rotates so that the first windward wall surface 30a is perpendicular to the direction of the air flow through the electric auxiliary heat 3.
The "initial state" of the electric auxiliary heat 3 may refer to an initial position state of the electric auxiliary heat 3, where the "initial state" may be a state of the electric auxiliary heat 3 preset by the air conditioner 100, may also be a state of the electric auxiliary heat 3 after the air conditioner 100 is used last time and the air conditioner 100 stops running, and may also be a state of the electric auxiliary heat 3 when the air conditioner 100 ends in a previous running mode during running, but is not limited thereto. Alternatively, the "initial state" of the electric auxiliary heat 3 may be preset such that the first windward wall surface 30a is perpendicular to the direction of the air flow through the electric auxiliary heat 3; alternatively, the "initial state" of the electric auxiliary heat 3 may be preset such that the second windward wall surface 30b is perpendicular to the direction of the air flow through the electric auxiliary heat 3.
It will be appreciated that before operation P2 needs to be performed, if the first windward wall 30a is already perpendicular to the direction of the air flow through the electric auxiliary heat 3, then the electric auxiliary heat 3 may not rotate to keep the first windward wall 30a perpendicular to the direction of the air flow through the electric auxiliary heat 3 when operation P2 is performed, and if the first windward wall 30a is not perpendicular to the direction of the air flow through the electric auxiliary heat 3, then the electric auxiliary heat 3 rotates until the first windward wall 30a is perpendicular to the direction of the air flow through the electric auxiliary heat 3 when operation P2 is performed.
Therefore, according to the control method of the air conditioner 100 in the embodiment of the invention, the state of the electric auxiliary heat 3 can be better matched with the running state (including running mode, gear and the like) of the air conditioner 100 and the position of the movable shell 12, so that various running states of the air conditioner 100 can be better considered, and the heating performance of the air conditioner 100 is ensured.
Alternatively, the turning on of the electric auxiliary heat 3 may be controlled according to the operation mode of the air conditioner 100. For example, if it is determined that the air conditioner 100 is in the heating mode, the electric auxiliary heat 3 is turned on, so that the electric auxiliary heat 3 heats the air flow flowing into the cabinet 1. For another example, when it is determined that the air conditioner 100 is in the heating mode, if the detected indoor temperature is less than the preset problem of the air conditioner 100, the electric auxiliary heat 3 is turned on, so that the electric auxiliary heat 3 heats the air flow flowing into the cabinet 1.
In some embodiments, as shown in fig. 11, the control method of the air conditioner 100 further includes step S4: when it is determined in step S2 that the movable housing 12 is located at the predetermined position and the air conditioner 100 is not in the heating mode, at this time, the movable housing 12 closes the second air inlet 100b, and the air conditioner 100 is in the cooling mode or the air supply mode or other operation modes other than the heating mode, the operation P3 is executed: the electric auxiliary heat 3 is closed and kept in an initial state, so that the electric auxiliary heat 3 does not rotate, the energy consumption is saved, and the cost is reduced.
Optionally, when the "initial state" of the electric auxiliary heat 3 is preset that the second windward wall surface 30b is perpendicular to the airflow direction flowing through the electric auxiliary heat 3, the windward area of the electric auxiliary heat 3 is smaller, so that the blocking effect of the electric auxiliary heat 3 on air is weakened, and other modes, such as a cooling mode, of the air conditioner 100 besides the heating mode are taken into consideration conveniently.
It will be appreciated that, before the operation P3 needs to be performed, if the electric auxiliary heat 3 is already turned off, the electric auxiliary heat 3 may be kept off when the operation P3 is performed, and if the electric auxiliary heat 3 is turned on, the electric auxiliary heat 3 may be turned off when the operation P3 is performed.
In some embodiments, as shown in fig. 11, the control method of the air conditioner 100 further includes step S5: when it is determined in step S2 that the movable housing 12 is away from the predetermined position and the air conditioner 100 is in the heating mode, the movable housing 12 opens the second air inlet 100b, and air can flow into the casing 1 through the first air inlet 100a and the second air inlet 100b, respectively, and then operation P4 is performed: the electric auxiliary heat 3 is started and the electric auxiliary heat 3 rotates to enable the first windward wall surface 30a to be perpendicular to the air flow direction flowing through the electric auxiliary heat 3, so that the windward area of the electric auxiliary heat 3 is larger, the condition that the air conditioner 100 cannot meet the heating requirement due to larger air inlet quantity is avoided, the efficiency of the electric auxiliary heat 3 is fully exerted, and the heating performance of the air conditioner 100 is ensured.
It can be understood that, before the operation P4 needs to be performed, if the electric auxiliary heat 3 is turned on, the electric auxiliary heat 3 is kept on when the operation P4 is performed, and if the electric auxiliary heat 3 is not turned on, the electric auxiliary heat 3 is turned on when the operation P4 is performed; also, before the operation P4 needs to be performed, if the first windward wall 30a is already perpendicular to the direction of the air flow through the electric auxiliary heat 3, the electric auxiliary heat 3 may not rotate to keep the first windward wall 30a perpendicular to the direction of the air flow through the electric auxiliary heat 3 when the operation P4 is performed, and if the first windward wall 30a is not perpendicular to the direction of the air flow through the electric auxiliary heat 3, the electric auxiliary heat 3 rotates until the first windward wall 30a is perpendicular to the direction of the air flow through the electric auxiliary heat 3 when the operation P4 is performed.
In some embodiments, as shown in fig. 11, when the movable housing 12 is rotatable relative to the fixed housing 11, the larger the rotation angle of the movable housing 12 relative to the predetermined position is, the larger the opening degree of the second air inlet 100b is, the larger the air inlet area at the second air inlet 100b is, and the direction of the air flow flowing through the electric auxiliary heater 3 will be changed correspondingly; in step S5, when the rotation angle of the movable housing 12 relative to the predetermined position is increased, the rotation angle of the electric auxiliary heat 3 relative to the initial state is increased, that is, the angle α is increased, and accordingly, when the rotation angle of the movable housing 12 relative to the predetermined position is reduced, the rotation angle of the electric auxiliary heat 3 relative to the initial state is reduced, so that it is convenient to ensure that the second windward wall surface 30b of the electric auxiliary heat 3 can be always perpendicular to the airflow direction flowing through the electric auxiliary heat 3, so as to fully exert the efficiency of the electric auxiliary heat 3. The "initial state" of the electric auxiliary heat 3 is preset such that the second windward wall surface 30b is perpendicular to the air flow direction flowing through the electric auxiliary heat 3.
In some embodiments, as shown in fig. 11, the control method of the air conditioner 100 further includes step S6: when it is determined in step S2 that the movable housing 12 is away from the predetermined position and the air conditioner 100 is not in the heating mode, at this time, the movable housing 12 opens the second air inlet 100b, and the air conditioner 100 is in other operation modes except the heating mode, such as the cooling mode or the air supply mode, and then the operation P5 is performed: the electric auxiliary heat 3 is closed and kept in an initial state, so that the electric auxiliary heat 3 does not rotate, thereby saving energy consumption and reducing cost.
Optionally, when the "initial state" of the electric auxiliary heat 3 is preset that the second windward wall surface 30b is perpendicular to the airflow direction flowing through the electric auxiliary heat 3, the windward area of the electric auxiliary heat 3 is smaller, so that the blocking effect of the electric auxiliary heat 3 on air is weakened, and other modes, such as a cooling mode, of the air conditioner 100 besides the heating mode are taken into consideration conveniently.
It will be appreciated that, before operation P5 needs to be performed, if electric auxiliary heat 3 is already turned off, electric auxiliary heat 3 may remain off when operation P5 is performed, and if electric auxiliary heat 3 is turned on, electric auxiliary heat 3 may be turned off when operation P5 is performed.
In some embodiments, as shown in fig. 11, the control method of the air conditioner 100 further includes step S7: the air conditioner 100 stops running, the electric auxiliary heat 3 is restored to the initial state, and the movable shell 12 is restored to the preset position, so that the electric auxiliary heat 3 and the movable shell 12 are reset, the whole control logic is more orderly, dust is prevented from falling into the shell 1 from the second air inlet 100b, and the inside cleaning of the air conditioner 100 is ensured.
In some embodiments, as shown in fig. 1, the first air inlet 100a is formed at the top of the fixed housing 11, and the electric auxiliary heat 3 is located below the first air inlet 100 a; in the initial state, the second windward wall surface 30b is disposed towards the first air inlet 100a, and the second windward wall surface 30b is disposed horizontally, so that the air flow at the first air inlet 100a may flow to the electric auxiliary heat 3 approximately along the vertical direction.
