[0048] Reference will now be made to Figures 1 to 6An air conditioner 10 and a control method thereof according to an embodiment of the present application will be described. In the description of the embodiments of the present application, the terms "inner", "outer", "upper", "lower", "top", "bottom", "lateral", "longitudinal" and the like indicate the orientation or positional relationship shown in the drawings based on the orientation or positional relationship shown in the drawings, and are merely used for the purpose of facilitating the description of the present application and simplifying the description, and thus cannot be construed as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus cannot be construed as limiting the present application. In order to facilitate the illustration of the structure of the device, some of the drawings of the present application are illustrated in a perspective form.

[0049] In the description of the embodiments of the present application, it should be understood that the term "a plurality of" means at least three, for example, three, four, etc. Unless otherwise specifically limited, when a certain feature "includes or comprises" a certain feature or features, it indicates that other features are not excluded and other features can be further included, unless otherwise specifically described.

[0050] In the description of the embodiments of the present application, the description with reference to the terms "one embodiment", "some embodiments", "some examples", "one example" and the like means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0051] One aspect of the present application provides an air conditioner 10. The present application does not make any limitation on the form of the air conditioner 10. The air conditioner 10 can be a cabinet air conditioner, a window air conditioner or other various forms of air conditioners 10. Figure 1 and Figure 2 An embodiment of a cabinet air conditioner 10 is shown.

[0052] Figure 1 is a schematic front view of an air conditioner 10 according to an embodiment of the present application, Figure 2 is a schematic side cross-sectional view of an air conditioner 10 according to an embodiment of the present application, as Figure 1 and Figure 2 The air conditioner 10 according to the embodiment of the present application includes a cabinet 100, an upper evaporator 210, a lower evaporator 220, an upper cross-flow fan 310 and a lower cross-flow fan 320, as shown in

[0053] The front side of the cabinet 100 is provided with an upper air outlet 101 and a lower air outlet 102, the rear side of the cabinet 100 is provided with an air inlet (not shown in the figure), and the inside of the cabinet 100 is formed with an accommodation space to accommodate the upper evaporator 210, the lower evaporator 220, the upper cross-flow fan 310 and the lower cross-flow fan 320, etc.

[0054] The air inlet can be an air inlet grille arranged at the rear side of the casing 100, and the air inlet extends longitudinally along the height direction of the casing 100. The air flow entering the casing 100 from the upper region of the air inlet can exchange heat with the upper evaporator 210, and then is blown out from the upper air outlet 101 under the action of the upper cross-flow fan 310; the air flow entering the casing 100 from the lower region of the air inlet can exchange heat with the lower evaporator 220, and then is blown out from the lower air outlet 102 under the action of the lower cross-flow fan 320.

[0055] In one example, the upper evaporator 210 and the lower evaporator 220 are arranged in parallel on the refrigerant pipeline of the air conditioner 10. For example, the upper evaporator 210 is first connected between the condenser and the compressor of the air conditioner 10, and then the lower evaporator 220 is connected in parallel with the upper evaporator 210. The refrigerant flowing out of the condenser can flow into only the upper evaporator 210 or only the lower evaporator 220, or flow into both the upper evaporator 210 and the lower evaporator 220, which is controlled by a valve group or the like.

[0056] In one example, the upper cross-flow fan 310 and the lower cross-flow fan 320 can have independent upper and lower air ducts. The upper air duct communicates the upper region of the air inlet and the upper air outlet 101, and the lower air duct communicates the lower region of the air inlet and the lower air outlet 102. The upper cross-flow fan 310 can be driven to rotate by the upper motor 311 arranged at the top of the upper cross-flow fan 310, and the lower cross-flow fan 320 can be driven to rotate by the lower motor 322 arranged at the bottom of the lower cross-flow fan 320. In this way, the upper cross-flow fan 310 and the lower cross-flow fan 320 can be independently controlled to rotate.

[0057] Further, referring to Figure 3 The rotation shafts of the upper cross-flow fan 310 and the lower cross-flow fan 320 are located on the same vertical axis, and a bearing member 330 is arranged between the upper cross-flow fan 310 and the lower cross-flow fan 320. The bearing member 330 is fixed in the casing 100, and the lower end of the rotation shaft of the upper cross-flow fan 310 and the upper end of the rotation shaft of the lower cross-flow fan 320 are rotatably connected to the bearing member 330 from the upper and lower sides. In this way, the upper cross-flow fan 310 or the lower cross-flow fan 320 can avoid producing abnormal noise due to deflection during operation.

[0058] In one example, the upper air outlet 101 is provided with upper swing leaves 110, which are mainly used to guide the up-down air outlet angle of the upper air outlet 101, or to open and close the upper air outlet 101. The number of the upper swing leaves 110 can be multiple, and each upper swing leaf 110 is arranged in sequence along the height direction of the casing and is rotatably mounted to the casing about a horizontal transverse axis.

[0059] Similarly, the lower air outlet 102 is provided with lower swing vanes 120, which are mainly used to guide the up-down air outlet angle of the lower air outlet 102, or to open and close the lower air outlet 102. The number of the lower swing vanes 120 can be multiple, and each lower swing vane 120 is arranged in sequence along the height direction of the shell, and each lower swing vane 120 is rotatably mounted to the shell around a horizontal transverse axis.

[0060] Each upper swing vane 110 or lower swing vane 120 can be matched with a motor (not shown in the figure), and each motor is independently controlled. In this way, the air conditioner 10 is more refined for the adjustment of the up-down air outlet angle.

[0061] It can be understood that, in the running process of the air conditioner 10, the shell 100 forms an adjusting air flow for adjusting the indoor air. The adjusting air flow can be a heat exchange air flow, which is used for temperature adjustment of the indoor environment. When the air conditioner 10 is in a cooling mode, the heat exchange air flow is cold air; when the air conditioner is in a heating mode, the heat exchange air flow is hot air. In addition, if the air conditioner 10 has additional adjustment functions such as dehumidification, humidification, purification, fresh air, etc., the adjusting air flow can also include dehumidified air flow, humidified air flow, purified air flow, fresh air flow, etc.

[0062] Figure 4 is a schematic block diagram of the air conditioner 10 according to an embodiment of the present application.

[0063] As Figure 4 shown, the air conditioner 10 of the embodiment of the present application further includes a controller 400. The controller 400 includes a processor 410 and a memory 420, and the memory 420 stores a machine executable program 421, which is executed by the processor 410 to implement the control method of the air conditioner 10 of any embodiment of the present application.

[0064] The memory 420 can include a memory and a non-volatile memory 420, and provide the processor 410 with execution instructions and data. Exemplarily, the memory can be a high-speed random access memory 420 (RAM), and the non-volatile memory 420 can be at least one disk memory 420.

[0065] In the embodiment, the processor 410 is an integrated circuit chip with the ability to process signals. The processor 410 can be a general-purpose processor 410, such as a central processing unit 410 (CPU), a network processor 410 (NP), a digital signal processor 410 (DSP), an application specific integrated circuit 410 (ASIC), a field-programmable gate array 410 (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, microprocessors 410, and other any conventional processors 410.

[0066] Another aspect of the present application provides a control method of an air conditioner 10.

[0067] Figure 5 is a schematic diagram of a control method of an air conditioner 10 according to an embodiment of the present application.

[0068] As shown in Figure 5 , the control method of the air conditioner 10 of the embodiment of the present application can generally include:

[0069] Step S502, starting the air conditioner 10.

[0070] Step S504, receiving a partition air supply instruction issued by a user.

[0071] Step S506, obtaining user information of an environment where the air conditioner 10 is located.

[0072] Step S508, controlling air supply states of the upper air outlet 101 and the lower air outlet 102 according to the user information.

[0073] The control method of the air conditioner 10 of the present application, after starting the air conditioner 10, if receiving a partition air supply instruction issued by a user, can obtain user information of an environment where the air conditioner 10 is located, and then reasonably control air supply states of the upper air outlet 101 and the lower air outlet 102 according to the user information, so as to carry out air supply pertinently, improve air supply effect, improve user comfort, and reduce user complaints.

[0074] In step S502, functions of the existing air conditioner 10 tend to be diversified, such as a cooling mode, a heating mode, a dehumidification mode, etc. After the air conditioner 10 is started this time, it continues to run according to the cooling mode, the heating mode, or the dehumidification mode, etc. executed last time by default.

[0075] In step S504, the zoned air supply instruction can be remotely sent by the user through a mobile device (such as a remote controller, a mobile phone, a tablet, etc.), or directly generated by the user operating the display screen of the air conditioner 10. After receiving the zoned air supply instruction, the air conditioner 10 will execute the zoned air supply process.

[0076] In step S506, the user information can include the number of users and the user positions. An image detection device can be arranged on the casing 100 of the air conditioner 10, which can be an image sensor. When obtaining the user information of the environment where the air conditioner 10 is located, the detection result of the image sensor can be obtained, and then the number of users and the user positions can be determined according to the detection result.

[0077] In an optional embodiment, when controlling the air supply states of the upper air outlet 101 and the lower air outlet 102 according to the user information, if the number of users is one, in the cooling mode, only the upper air outlet 101 is controlled to supply air, and in the heating mode, only the lower air outlet 102 is controlled to supply air. Since the number of users is one, the demand for cold or heat is less, in the cooling mode, the upper air outlet 101 blows cold air, and in the heating mode, the lower air outlet 102 blows hot air, which is conducive to well achieving the cold air updraft and the hot air downdraft, so that the indoor environment can be quickly made more comfortable.

[0078] In the above embodiment, in the cooling mode, the upper air outlet 101 is opened to blow air, and the lower air outlet 102 remains in a closed state, at this time, only the upper evaporator 210 and the upper cross-flow fan 310 work. In the heating mode, the lower air outlet is opened to blow hot air, and the upper air outlet 101 remains closed, at this time, only the lower evaporator 220 and the lower cross-flow fan 320 work.

[0079] In an optional embodiment, when controlling the air supply states of the upper air outlet 101 and the lower air outlet 102 according to the user information, if the number of users is two, in the cooling mode, the upper air outlet 101 is controlled to supply air to the user who is closer, and the lower air outlet 102 is controlled to supply air to the user who is farther away, and in the heating mode, the upper air outlet 101 is controlled to supply air to the user who is farther away, and the lower air outlet 102 is controlled to supply air to the user who is closer. In this way, in the cooling mode, the users who are close and far away can both experience the air supply effect of cold air downdraft, and in the heating mode, the users who are close and far away can both experience the air supply effect of hot air updraft.

[0080] In the above embodiment, since in the cooling mode, the upper air outlet 101 supplies air to the user who is closer, and the lower air outlet 102 supplies air to the user who is farther away, the two air flows can intersect, at this time, the rotation speed of the lower cross-flow fan 320 can be increased, or the wind pressure at the lower air outlet 102 can be increased by adjusting the lower swing vane 120, so as to ensure that the cold air can be effectively blown to the user who is farther away.

[0081] In particular, when the distance between the two users is the same, the upper air outlet 101 and the lower air outlet 102 can be controlled to alternately blow air to the two users, preventing the air from being blown to the users from the same angle for a long time, thereby avoiding causing discomfort to the users.

[0082] Further, when controlling the blowing state of the upper air outlet 101 and the lower air outlet 102 according to the user information, if the number of users is multiple, in the cooling mode, the upper air outlet 101 can be controlled to blow air to the user sending the zoned blowing instruction, and the lower air outlet 102 can be controlled to sweep air, and in the heating mode, the lower air outlet 102 can be controlled to blow air to the user sending the zoned blowing instruction, and the upper air outlet 101 can be controlled to sweep air. In this way, the user sending the zoned blowing instruction can be preferentially blown air, thereby ensuring the comfort experience of the user.

[0083] In the above embodiment, controlling the upper air outlet 101 or the lower air outlet 102 to sweep air can be to control the upper swing leaf 110 or the lower swing leaf 120 to swing up and down, thereby increasing the up and down blowing angle and improving the uniformity of the blowing air, so that the other users except the user sending the zoned blowing instruction can uniformly feel the cold or heat.

[0084] In an optional embodiment, after controlling the blowing state of the upper air outlet 101 and the lower air outlet 102 according to the user information, the air conditioner 10 can further wait for a preset time length and reacquire the user information of the environment where the air conditioner 10 is located, and then adjust the blowing state of the upper air outlet 101 and the lower air outlet 102 according to the reacquired user information.

[0085] Since the number of users and the user position can change at any time, by waiting for a preset time length, the blowing state of the upper air outlet 101 and the lower air outlet 102 can be adjusted frequently. The preset time length can be artificially set, for example, 10 minutes, 15 minutes, 20 minutes, etc.

[0086] In an optional embodiment, after the air conditioner 10 is started, if no zoned blowing instruction sent by the user is received, the air conditioner 10 will operate according to the default cooling mode, heating mode or dehumidification mode. In the cooling mode, only the upper air outlet 101 is controlled to blow air, preventing cold air from blowing the legs, and in the heating mode, only the lower air outlet 102 is controlled to blow air, preventing hot air from blowing the head, thereby avoiding causing discomfort.

[0087] Further, in the dehumidification mode, the ambient temperature of the environment where the air conditioner 10 is located can be acquired, if it is found that the ambient temperature is lower than the set temperature of the user, the upper air outlet 101 can be controlled to blow dehumidified air, and the lower air outlet 102 can be controlled to blow heated air, so as to adjust the indoor temperature by using the heated air, thereby achieving the purpose of dehumidification without temperature drop, and guaranteeing the use experience of the user. If it is found that the ambient temperature is higher than or equal to the set temperature of the user, only the upper air outlet 101 can be controlled to blow dehumidified air, thereby achieving rapid dehumidification.

[0088] It can be understood that when the upper air outlet 101 blows dehumidified air flow and the lower air outlet 102 blows heated air flow, the upper evaporator 210 is used for dehumidification and the lower evaporator 220 is used for heating, which can be realized by adjusting the amount of refrigerant flowing through the upper evaporator 210 and the lower evaporator 220 through valves and other components.

[0089] Figure 6 The flow chart of the control method of the air conditioner 10 according to another embodiment of the present application is mainly applied to the default mode of the air conditioner 10, i.e., the air conditioner 10 does not issue a partitioned air supply instruction from the user during operation. As shown in FIG. 6, the control method can generally include: Figure 6

[0090] Step S602, starting the air conditioner 10.

[0092] Step S606, controlling only the upper air outlet 101 to supply air.

[0093] Step S608, determining whether the air conditioner 10 executes a heating mode, if yes, executing step S610, if no, executing step S612.

[0094] Step S610, controlling only the lower air outlet 102 to supply air.

[0095] Step S612, confirming that the air conditioner 10 executes a dehumidification mode.

[0096] Step S614, obtaining the ambient temperature of the environment where the air conditioner 10 is located.

[0097] Step S618, determining whether the ambient temperature of the environment where the air conditioner 10 is located is lower than the set temperature of the user, if yes, executing step S620, if no, executing step S622.

[0098] Step S620, controlling the upper air outlet 101 to blow dehumidified air flow and controlling the lower air outlet 102 to blow heated air flow.

[0099] Step S622, controlling only the upper air outlet 101 to blow dehumidified air flow.

[0100] At this point, those skilled in the art should recognize that although the present application has been fully shown and described with reference to a plurality of exemplary embodiments, many other variations or modifications can be directly determined or deduced from the disclosure of the present application in accordance with the principles of the present application without departing from the spirit and scope of the present application.
