To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples.

In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the applicability of other processes and/or the use of other materials.
Next, an air conditioner 100 according to an embodiment of the first aspect of the present invention is described with reference to the drawings.
As shown in fig. 1 and 2, the air conditioner 100 has a first intake opening 100a and a second intake opening 100b, and external air may flow into the air conditioner 100 through the first intake opening 100a and the second intake opening 100b, respectively. It is understood that the first and second air inlets 100a and 100b may be spaced apart or not, and the first and second air inlets 100a and 100b may communicate with each other.
The air conditioner 100 includes a casing 1 and a heat exchanger 2, the casing 1 includes a fixed housing 11 and a movable housing 12, a first air inlet 100a is formed on the fixed housing 11, the movable housing 12 is movable relative to the fixed housing 11, when the movable housing 12 is located at a predetermined position, the movable housing 12 closes a second air inlet 100b, at this time, the external air cannot flow into the casing 1 through the second air inlet 100b, when the movable housing 12 leaves the predetermined position, the movable housing 12 opens the second air inlet 100b, at this time, the external air can flow into the casing 1 through the second air inlet 100 b. The heat exchanger 2 is disposed in the cabinet 1 to exchange heat with the air flowing into the cabinet 1, and then the air flows into the cabinet 1 through the first air inlet 100a to exchange heat with the heat exchanger 2, and/or the air flows into the cabinet 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), the external air may flow into the cabinet 1 through the first air intake opening 100a to exchange heat with the heat exchanger 2, and if the movable housing 12 is moved from the predetermined position (as shown in fig. 4), the external air may flow into the cabinet 1 through the first and second air intake openings 100a and 100b, respectively, to exchange heat with the heat exchanger 2. The second air inlet 100b may be formed on the stationary housing 11, but is not limited thereto.
As shown in fig. 1 and 2, the air conditioner 100 further includes an electric auxiliary heater 3, the electric auxiliary heater 3 is rotatably disposed in the casing 1, the electric auxiliary heater 3 can heat air flowing into the casing 1, the electric auxiliary heater 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 both extend along a length direction (e.g., a left-right direction in the drawing) of the electric auxiliary heater 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 100 b. The driving device 4 further includes a second driving device 42, the second driving device 42 is connected to the electric auxiliary heater 3 to drive the electric auxiliary heater 3 to rotate, so that the electric auxiliary heater 3 rotates around an axis extending along the length direction of the electric auxiliary heater 3, and during the rotation of the electric auxiliary heater 3, the positions of the first windward wall 30a and the second windward wall 30b relative to the first air inlet 100a are changed, so as to adjust the windward area (or windward area) of the electric auxiliary heater 3.
For example, when the electric auxiliary heat 3 is required to be used, such as the air conditioner 100 is in the 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 high, the wind speed is large, the wind volume of the air conditioner 100 is large, the second driving means 42 may drive the electric auxiliary heater 3 to rotate, so that the electric auxiliary heater 3 rotates until the first windward wall surface 30a is perpendicular to the direction of the airflow flowing through the electric auxiliary heater 3, since the area of the first windward wall surface 30a is larger than that of the second windward wall surface 30b, the contact area of the electric auxiliary heater 3 and the air (i.e., the wind receiving area of the electric auxiliary heater 3) is larger at this time, it can be understood that the larger the wind receiving area of the electric auxiliary heater 3 is, the slower the air flows, and the longer the contact area and the contact time between the electric auxiliary heater 3 and the air are, which is beneficial to the electric auxiliary heater 3 to fully heat the air flow flowing through the electric auxiliary heater 3, and ensures the heating performance of the air conditioner 100; if the gear of the air conditioner 100 is low, the electric auxiliary heater 3 may not be operated, for example, the electric auxiliary heater 3 may be in a state where the second windward wall 30b is perpendicular to the direction of the airflow flowing through the electric auxiliary heater 3, which may not only ensure that the electric auxiliary heater 3 satisfies the heating capacity of the air conditioner 100, but also reduce the contact area between the electric auxiliary heater 3 and the air, thereby reducing the blocking effect of the electric auxiliary heater 3 on the air and facilitating the guarantee of the air output and the air output speed of the air conditioner 100.
For another example, when the electric auxiliary heater 3 needs to be used, for example, the air conditioner 100 is in the heating mode and the movable housing 12 is away from the predetermined position to open the second air inlet 100b, at this time, the air intake of the air conditioner 100 is relatively large, the second driving device 42 can drive the electric auxiliary heater 3 to rotate, so that the electric auxiliary heater 3 rotates to the position where the first windward wall 30a is perpendicular to the direction of the airflow flowing through the electric auxiliary heater 3, thereby preventing the air conditioner 100 from being unable to meet the heating requirement due to the relatively large air intake, and effectively ensuring the heating performance of the air conditioner 100.
For another example, when the electric auxiliary heater 3 is not needed, for example, the air conditioner 100 is in the cooling mode, the electric auxiliary heater 3 is turned off at this time, and the electric auxiliary heater 3 may be in a state where the second windward wall surface 30b is perpendicular to the direction of the airflow flowing through the electric auxiliary heater 3, so as to weaken the blocking effect of the electric auxiliary heater 3 on the air, effectively solve the problem of wind shielding of the electric auxiliary heater 3, and ensure the usability of the air conditioner 100.
It is to be understood that the rotation control of the electric assist heat 3 is not limited thereto.
Therefore, compared with the mode that the electric auxiliary heater 3 is fixedly arranged in the casing 1 in some technologies, the windward area of the electric auxiliary heater 3 is fixed, which easily causes that the refrigeration performance and the heating performance of the air conditioner 100 cannot be simultaneously considered; air conditioner 100 in this application has first air intake 100a and second air intake 100b, make the air current direction in the casing 1 have the uncertainty, through setting up movable housing 12 and electric auxiliary heating 3, and make first drive arrangement 41 drive movable housing 12 motion, second drive arrangement 42 drives electric auxiliary heating 3 and rotates, thereby the operating mode of air conditioner 100 has been enriched, and can be through controlling first drive arrangement 41 and second drive arrangement 42, be convenient for make the state that electric auxiliary heating 3 locates and the operating condition (including operating mode, the gear etc.) of air conditioner 100 and the position phase-match that locates of movable housing 12, in order to compromise the multiple operating condition of air conditioner 100 better, and then guarantee the refrigeration of air conditioner 100, heating performance.
It is understood that the first windward wall 30a and the second windward wall 30b may be directly connected, or the first windward wall 30a and the second windward wall 30b may be spaced apart, in which case the first windward wall 30a and the second windward wall 30b may be connected by other walls of the electric auxiliary heater 3. The first windward wall 30a may be a plane or a curved surface, and the second windward wall 30b may be a plane or a curved surface.
For example, in the example of fig. 1 to 4, the electric auxiliary heater 3 is a PTC electric auxiliary heater, the cross-sectional shape of the electric auxiliary heater 3 is a rectangle, the first and second windward wall surfaces 30a and 30b are each formed as a plane, and the first and second windward wall surfaces 30a and 30b are disposed adjacently.

Other configurations 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 second aspect embodiment of the present invention will be described with reference to the drawings, wherein the air conditioner 100 is the air conditioner 100 according to the above-described first aspect embodiment of the present invention.
For example, as shown in fig. 10 and 11, the air conditioner 100 has a first gear to an M-th gear, and the wind speed of the air conditioner 100 gradually increases from the first gear to the M-th gear. The control method of the air conditioner 100 includes the steps of:
s1: the air conditioner 100 is operated, and the electric auxiliary heater 3 is in an initial state;
s2: judging whether the movable housing 12 is located at a predetermined position, and judging whether the air conditioner 100 is in a heating mode;
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 shift position of the air conditioner 100 is located between the first shift position and the nth shift position, and if so, operation P1 is performed: the electric auxiliary heater 3 is maintained in the initial state, and if not, operation P2 is performed: the electric auxiliary heat 3 is rotated so that the first windward wall surface 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 heater 3 is in an initial state; s2: judging whether the movable shell 12 is positioned at a preset position, judging whether the air conditioner 100 is in a heating mode, namely judging whether the movable shell 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 located at a preset position and the air conditioner 100 is in a heating mode, the electric auxiliary heater 3 is turned on, at this time, the electric auxiliary heater 3 can heat airflow flowing through the electric auxiliary heater 3, whether the gear of the air conditioner 100 is located between a first gear and an N gear (including the first gear and the N gear) is judged, N is less than M, if yes, the air conditioner 100 runs at a low windshield, at this time, the electric auxiliary heater 3 does not act and still keeps in an initial state, namely, the electric auxiliary heater 3 does not rotate, the heating capacity of the air conditioner 100 is met, meanwhile, the electric auxiliary heater 3 does not need to be driven to rotate, the energy consumption is saved, and the cost is reduced; if not, the air conditioner 100 is indicated to use a high wind level or a strong wind level, at this time, the electric auxiliary heater 3 rotates, so that the first windward wall surface 30a is perpendicular to the direction of the airflow flowing through the electric auxiliary heater 3, that is, the electric auxiliary heater 3 rotates to a state that the first windward wall surface 30a is perpendicular to the direction of the airflow flowing through the electric auxiliary heater 3, so that the electric auxiliary heater 3 fully heats the airflow flowing through the electric auxiliary heater 3, and the heating performance of the air conditioner 100 is ensured while a large air output of the air conditioner 100 is realized. Wherein M can be a positive integer greater than 1, N is greater than or equal to 1 and less than M, and N can be a positive integer.
Therefore, the running state of the electric auxiliary heater 3 is reasonably set, so that the running state (including the running mode, the gear and the like) of the air conditioner 100 and the position of the movable shell 12 are matched, the multiple running states of the air conditioner 100 are better considered, and the heating performance of the air conditioner 100 is further ensured.
It should be noted that the sequence of each action in the same step is not fixed. For example, in step S2, the order of "determining whether the movable housing 12 is located at the predetermined position" and "determining 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 first and then the air conditioner 100 is in the heating mode, or it may be determined whether the air conditioner 100 is in the heating mode first and then the movable housing 12 is located at the predetermined position.
Specifically, in step S2, it is determined whether the movable housing 12 is located at the predetermined position and then the air conditioner 100 is in the heating mode, and the method for controlling the air conditioner 100 may include: the air conditioner 100 operates, the electric auxiliary heater 3 is in an initial state, whether the movable casing 12 is located at a preset 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 judgment result, the electric auxiliary heater 3 is turned on, whether the gear of the air conditioner 100 is located in a first gear to an nth gear is judged, and if yes, operation P1 is executed: the electric auxiliary heater 3 remains in the initial state, and if not, operation P2 is performed: the electric supplementary heat 3 is rotated so that the first windward wall surface 30a is perpendicular to the direction of the air flow passing through the electric supplementary heat 3. Alternatively, in step S2, it is determined whether the air conditioner 100 is in the heating mode and then whether the movable housing 12 is located at the predetermined position, where the method for controlling the air conditioner 100 may include: the air conditioner 100 operates, the electric auxiliary heater 3 is in an initial state, whether the air conditioner 100 is in a heating mode is judged, if yes, whether the movable casing 12 is located at a preset position is judged, when the judgment result is that the movable casing 12 is located at the preset position, the electric auxiliary heater 3 is turned on, whether the gear of the air conditioner 100 is located at a first gear to an nth gear is judged, and if yes, operation P1 is executed: the electric auxiliary heater 3 remains in the initial state, and if not, operation P2 is performed: the electric supplementary heat 3 is rotated so that the first windward wall surface 30a is perpendicular to the direction of the air flow passing through the electric supplementary heat 3.
The "initial state" of the electric auxiliary heater 3 may refer to an initial position state of the electric auxiliary heater 3, and the "initial state" may be a state of the electric auxiliary heater 3 preset by the air conditioner 100, may also be a state of the electric auxiliary heater 3 after the air conditioner 100 is used last time and the air conditioner 100 stops operating, and may also be a state of the electric auxiliary heater 3 when the air conditioner 100 is in an operating process and a previous operating mode is finished, but is not limited thereto. Alternatively, the "initial state" of the electric supplementary heat 3 may be preset such that the first windward wall surface 30a is perpendicular to the direction of the airflow flowing through the electric supplementary heat 3; alternatively, the "initial state" of the electric supplementary heat 3 may be preset such that the second windward wall surface 30b is perpendicular to the direction of the airflow flowing through the electric supplementary heat 3.
It is understood that before the operation P2 needs to be performed, if the first windward wall surface 30a is already perpendicular to the direction of the airflow through the electric auxiliary heater 3, the electric auxiliary heater 3 may not rotate to keep the first windward wall surface 30a perpendicular to the direction of the airflow through the electric auxiliary heater 3 when the operation P2 is performed, and if the first windward wall surface 30a is not perpendicular to the direction of the airflow through the electric auxiliary heater 3, the electric auxiliary heater 3 rotates to make the first windward wall surface 30a perpendicular to the direction of the airflow through the electric auxiliary heater 3 when the operation P2 is performed.
Therefore, according to the control method of the air conditioner 100 in the embodiment of the present invention, the state of the electric auxiliary heater 3 can be better matched with the operation state (including the operation mode, the gear position, etc.) of the air conditioner 100 and the position of the movable housing 12, so as to better consider various operation states of the air conditioner 100 and ensure the heating performance of the air conditioner 100.
Alternatively, the turning on of the electric supplementary heat 3 may be controlled according to the operation mode of the air conditioner 100. For example, as long as it is judged that the air conditioner 100 is in the heating mode, the electric supplementary heat 3 is turned on so that the electric supplementary 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 a preset problem of the air conditioner 100, the electric auxiliary heater 3 is turned on so that the electric auxiliary heater 3 heats the airflow 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 casing 12 is located at the predetermined position and the air conditioner 100 is not in the heating mode, the movable casing 12 closes 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 blowing mode, operation P3 is performed: the electric auxiliary heater 3 is turned off and kept in an initial state, so that the electric auxiliary heater 3 does not rotate, energy consumption is saved, and cost is reduced.
Alternatively, when the "initial state" of the electric auxiliary heater 3 is preset to be that the second windward wall surface 30b is perpendicular to the direction of the airflow flowing through the electric auxiliary heater 3, the windward area of the electric auxiliary heater 3 is small, so that the blocking effect of the electric auxiliary heater 3 on the air is weakened, and the air conditioner 100 can be compatible with other modes besides the heating mode, such as the cooling mode.
It is understood that before the operation P3 needs to be performed, if the electric auxiliary heater 3 is turned off, the electric auxiliary heater 3 is kept turned off when the operation P3 is performed, and if the electric auxiliary heater 3 is turned on, the electric auxiliary heater 3 is 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 the step S2 that the movable housing 12 leaves the predetermined position and the air conditioner 100 is in the heating mode, and the movable housing 12 opens the second air inlet 100b, air can flow into the cabinet 1 through the first air inlet 100a and the second air inlet 100b, respectively, operation P4 is performed: the electric auxiliary heater 3 is turned on and the electric auxiliary heater 3 rotates to enable the first windward wall surface 30a to be perpendicular to the direction of airflow flowing through the electric auxiliary heater 3, so that the windward area of the electric auxiliary heater 3 is large, the problem that the air conditioner 100 cannot meet the heating requirement due to large air intake is avoided, the efficiency of the electric auxiliary heater 3 is fully exerted, and the heating performance of the air conditioner 100 is guaranteed.
It is understood that before the operation P4 needs to be performed, if the electric auxiliary heater 3 is turned on, the electric auxiliary heater 3 is turned on when the operation P4 is performed, and if the electric auxiliary heater 3 is not turned on, the electric auxiliary heater 3 is turned on when the operation P4 is performed; also, before the operation P4 needs to be performed, if the first windward wall surface 30a is already perpendicular to the direction of the airflow through the electric auxiliary heater 3, the electric auxiliary heater 3 may not be rotated to keep the first windward wall surface 30a perpendicular to the direction of the airflow through the electric auxiliary heater 3 when the operation P4 is performed, and if the first windward wall surface 30a is not perpendicular to the direction of the airflow through the electric auxiliary heater 3, the electric auxiliary heater 3 is rotated until the first windward wall surface 30a is perpendicular to the direction of the airflow through the electric auxiliary heater 3 when the operation P4 is performed.
In some embodiments, as shown in fig. 11, 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 airflow flowing through the electric auxiliary heater 3 is changed accordingly, in step S5, when the rotation angle of the movable housing 12 relative to the predetermined position is increased, that is, the rotation angle of the electric auxiliary heater 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 decreased, the rotation angle of the electric auxiliary heater 3 relative to the initial state is decreased, so as to ensure that the first windward wall 30a of the electric auxiliary heater 3 can be always perpendicular to the direction of the airflow flowing through the electric auxiliary heater 3, so as to fully exert the efficiency of the electric auxiliary heater 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 casing 12 leaves the predetermined position and the air conditioner 100 is not in the heating mode, in which the movable casing 12 opens the second air inlet 100b and the air conditioner 100 is in the cooling mode or the air blowing mode, or other operation modes except the heating mode, operation P5 is performed: the electric auxiliary heater 3 is turned off and kept in an initial state, and the electric auxiliary heater 3 does not rotate, so that the energy consumption is saved and the cost is reduced.
Alternatively, when the "initial state" of the electric auxiliary heater 3 is preset to be that the second windward wall surface 30b is perpendicular to the direction of the airflow flowing through the electric auxiliary heater 3, the windward area of the electric auxiliary heater 3 is small, so that the blocking effect of the electric auxiliary heater 3 on the air is weakened, and the air conditioner 100 can be compatible with other modes besides the heating mode, such as the cooling mode.
It is understood that before the operation P5 needs to be performed, if the electric auxiliary heater 3 is turned off, the electric auxiliary heater 3 is kept turned off when the operation P5 is performed, and if the electric auxiliary heater 3 is turned on, the electric auxiliary heater 3 is turned off when the operation P5 is performed.
In some embodiments, as shown in fig. 11, the control method of the air conditioner 100 further includes step S7: air conditioner 100 out of service, electricity assist heat 3 to reply to initial condition, and movable housing 12 replies to preset position, then electricity assist heat 3 and movable housing 12 all realized resetting, are favorable to making whole control logic more organized, and avoid the dust to fall to casing 1 in from second air intake 100b, are convenient for guarantee the inside clean of air conditioner 100.
In some embodiments, as shown in fig. 1, the first air inlet 100a is formed at the top of the stationary housing 11, and the electric supplementary heat 3 is located below the first air inlet 100 a; in an initial state, the second windward wall 30b is disposed toward the first air inlet 100a, and the second windward wall 30b is disposed horizontally, so that the airflow at the first air inlet 100a can flow to the electric auxiliary heater 3 substantially along a vertical direction.
