[0051] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0052] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific processes and examples of materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0053] Hereinafter, an air conditioner indoor unit 100 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0054] like Figure 1 and Figure 3 As shown, the air-conditioning indoor unit 100 includes a shell component 1, and the shell component 1 has a first air duct 11 and a second air duct 12 arranged at intervals. The shell component 1 also has a first air inlet 11a, a second air inlet 12a, a first air outlet 11b and a second air outlet 12b. The first air inlet 11a and the first air outlet 11b are respectively connected to the first air duct 11, and the second air inlet 12a and the second air outlet 12b are respectively connected to the second air duct 12; then the airflow at the first air inlet 11a can flow into the first air duct 11 through the first air inlet 11a and be blown out from the first air outlet 11b, and the airflow at the second air inlet 12a can flow into the second air duct 12 through the second air inlet 12a and be blown out from the second air outlet 12b. Among them, the first air duct 11 is connected to the second air duct 12 through the connecting port 140. For example, part of the airflow in the first air duct 11 can flow into the second air duct 12 through the connecting port 140 and blow out from the second air outlet 12b, and / or part of the airflow in the second air duct 12 can flow into the first air duct 11 through the connecting port 140 and blow out from the first air outlet 11b.

[0055] The air-conditioning indoor unit 100 also includes a heat exchange component 2 and a first wind wheel component 3. The heat exchange component 2 is arranged in the first air duct 11, and in the air flow direction, the connecting port 140 is located on the downstream side of the heat exchange component 2. The airflow in the first air duct 11 first flows through the heat exchange component 2 and then flows to the connecting port 140. That is to say, when the heat exchange component 2 is in operation, the airflow flowing to the connecting port 140 is the airflow after heat exchange with the heat exchange component 2. The first wind wheel component 3 is also arranged in the first air duct 11. The first wind wheel component 3 can be used to drive the airflow in the first air duct 11 to realize the air intake and air outlet of the first air duct 11. The heat exchange component 2 can exchange heat with the airflow flowing through it to at least change the air outlet temperature of the first air duct 11. For example, when the heat exchange component 2 is running, if the connecting port 140 is closed, the airflow in the first air duct 11 cannot flow into the second air duct 12, and the heat exchange component 2 can be used to change the outlet air temperature of the first air duct 11. If the connecting port 140 is opened, the airflow in the first air duct 11 after heat exchange with the heat exchange component 2 flows into the second air duct 12, then the heat exchange component 2 can also be used to indirectly change the outlet air temperature of the second air duct 12.

[0056] The air conditioning indoor unit 100 also includes a second wind wheel component 4, which is arranged in the second air duct 12. The second wind wheel component 4 can be used to drive the air flow in the second air duct 12 to realize the air intake and air outlet of the second air duct 12, and if the connecting port 140 is closed, it will not affect the air intake and air outlet of the second air duct 12.

[0057] like Figure 3 , Fig. 9 and Fig.11 As shown, the air conditioner indoor unit 100 further includes a switching component 5, the switching component 5 includes a switching member 51, the switching member 51 is movably disposed in the second air duct 12, and the switching member 51 has a first state and a second state. Figure 5 As shown in FIG. 1 , the switching member 51 closes the second air inlet 12a and the switching member 51 opens the connecting port 140. At this time, the airflow in the first air duct 11 can flow into the second air duct 12 through the connecting port 140. The second air duct 12 can be inlet through the connecting port 140, but cannot be inlet through the second air inlet 12a. In the second state (as shown in FIG. 1 ), the switching member 51 closes the second air inlet 12a and opens the connecting port 140. At this time, the airflow in the first air duct 11 can flow into the second air duct 12 through the connecting port 140. The second air duct 12 can be inlet through the connecting port 140, but cannot be inlet through the second air inlet 12a. Figure 4 As shown), the switching member 51 closes the connecting port 140 and opens the second air inlet 12a. At this time, the airflow in the first air duct 11 cannot flow into the second air duct 12 through the connecting port 140. The second air duct 12 can take in air through the second air inlet 12a, but cannot take in air through the connecting port 140.

[0058] Obviously, the switching member 51 switches between the first state and the second state to switch the air intake mode of the second air duct 12. When the heat exchange component 2 is in operation, the air intake modes of the second air duct 12 are different, which may affect the air intake temperature of the second air duct 12 under certain circumstances, thereby affecting the air outlet temperature of the second air duct 12, and then facilitates switching the second air duct 12 to a suitable air intake mode according to the actual environment.

[0059] For example, taking the air-conditioning indoor unit 100 for cooling as an example, those skilled in the art can easily understand the scheme of using the air-conditioning indoor unit 100 for other operations such as heating after reading the following description. When the difference between the ambient temperature and the set temperature of the air-conditioning indoor unit 100 is large, rapid cooling is required at this time, and the switching element 51 can be switched to the first state. After the airflow has exchanged heat with the heat exchange component 2, a part of it is blown out from the first air outlet 11b, and the other part flows into the second air duct 12 through the connecting port 140 and is blown out from the second air outlet 12b, so as to quickly reduce the ambient temperature. The air-conditioning indoor unit 100 can be in a strong cooling mode; when the difference between the ambient temperature and the set temperature of the air-conditioning indoor unit 100 is small, it is basically determined that the ambient temperature has dropped to a comfortable temperature. At this time, it is necessary to continue to keep the ambient temperature basically constant. The switching element 51 can be switched to the second state. After the airflow has exchanged heat with the heat exchange component 2, it is blown out from the first air outlet 11b, while the airflow in the second air duct 12 does not exchange heat with the heat exchange component 2. The airflow flows from the second air inlet 12a to the second air duct 12 and is blown out from the second air outlet 12b. The air-conditioning indoor unit 100 can be in a comfortable cooling mode.

[0060] It can be seen that in the strong cooling mode, the airflows blown out of the first air duct 11 and the second air duct 12 are both airflows after heat exchange with the heat exchange component 2, so as to quickly cool down; while in the comfortable cooling mode, the airflow blown out of the first air duct 11 is the airflow after heat exchange with the heat exchange component 2, and the airflow blown out of the second air duct 12 is not heat exchanged with the heat exchange component 2. The second air duct 12 can play the role of circulating the air in the environment so as to keep the ambient temperature basically constant. Among them, since the first air outlet 11b and the second air outlet 12b are arranged at intervals, it is convenient to expand the air supply range of the air conditioner indoor unit 100, whether in the strong cooling mode or in the comfortable cooling mode, which is conducive to improving the cooling rate in the strong cooling mode and further maintaining the constant comfortable temperature in the comfortable cooling mode.

[0061] According to the air-conditioning indoor unit 100 of the embodiment of the present invention, by setting the switching component 5, and making the switching component 51 have a first state and a second state, in the first state, the air-conditioning indoor unit 100 can quickly adjust the ambient temperature, and in the second state, the air-conditioning indoor unit 100 can keep the ambient temperature basically constant, so as to provide a constant temperature and comfortable environment without the need for frequent manual adjustment by the user, and has good practicality.

[0062] It is understandable that in the above technical solution of the present application, there is no specific restriction on the structure of the switching member 51 and the movement mode of the switching member 51. For example, the switching member 51 may be composed of only one component, or the switching member 51 may include multiple components, each of which is movably matched with the housing component 1, and the movement directions of the multiple components relative to the housing component 1 may be the same or different; the switching member 51 may move or rotate relative to the housing component 1, but is not limited thereto.

[0063] In some embodiments, Figure 6 and Figure 7 , Fig. 9 , Fig.11 As shown, the second air inlet 12a is provided on both sides of the connecting port 140 in the first direction, and the air conditioner indoor unit 100 has a plurality of second air inlets 12a, which is conducive to appropriately increasing the air intake of the second air duct 12 when the second air duct 12 is air-intaked through the second air inlet 12a; the switching member 51 is movable along the second direction, and the second direction intersects with the first direction, that is, the second direction is not parallel to the first direction. Thus, it is convenient for the switching member 51 to switch between the first state and the second state by moving relative to the shell part 1. At the same time, since the arrangement direction of the connecting port 140 and the second air inlet 12a intersects with the moving direction of the switching member 51, it is conducive to saving the space occupied by the air conditioner indoor unit 100 in the first direction, and reasonably utilizing the arrangement space provided by the air conditioner indoor unit 100 in the second direction, and it is convenient for the switching member 51 to simultaneously close all the second air inlets 12a in the first state, and simultaneously open all the second air inlets 12a in the second state.

[0064] For example, the second direction is perpendicular to the first direction, which is beneficial to further save the space occupied by the air-conditioning indoor unit 100 in the first direction; Figure 6 and Fig. 9 In the example, the plurality of second air inlets 12a are arranged at intervals in the horizontal direction, and the connecting port 140 and the second air inlet 12a are arranged at intervals in the horizontal direction, and the switching member 51 can move relative to the shell component 1 in the vertical direction.

[0065] It should be noted that, in the above technical solution, there is no specific restriction on the relative positions of the connecting port 140 and the second air inlet 12a in the direction perpendicular to the first direction; for example, taking the first direction as the horizontal direction, in the vertical direction, the connecting port 140 and the multiple second air inlets 12a can be at the same height position, or the connecting port 140 and at least two of the multiple second air inlets 12a (for example, the connecting port 140 and at least one second air inlet 12a, or at least two second air inlets 12a) are at different height positions respectively.

[0066] Of course, the arrangement of the communication port 140 and the plurality of second air inlets 12 a is not limited thereto. For example, the plurality of second air inlets 12 a may also be disposed on the same side of the communication port 140 .

[0067] In other embodiments, when there is only one second air inlet 12a, the switching member 51 can move relative to the shell component 1, or the switching member 51 can rotate relative to the shell component 1 to achieve switching between the first state and the second state.

[0068] In some embodiments, Fig. 9 and Fig.11 As shown, the switching member 51 includes a first baffle plate 511 and a second baffle plate 512. The first baffle plate 511 is used for switching the connecting port 140. Each second baffle plate 512 is used for switching the corresponding second air inlet 12a. An opening 512a is formed on the second baffle plate 512. The opening 512a can penetrate the second baffle plate 512 along the thickness direction of the second baffle plate 512.

[0069] In the first state, the first baffle plate 511 is offset from the connecting port 140, and the opening 512a is offset from the corresponding second air inlet 12a, so that the first baffle plate 511 avoids the connecting port 140 to open the connecting port 140, and the second baffle plate 512 blocks the second air inlet 12a to close the second air inlet 12a; in the second state, the first baffle plate 511 is opposite to the connecting port 140, and the opening 512a is opposite to the corresponding second air inlet 12a, so that the first baffle plate 511 blocks the connecting port 140 to close the connecting port 140, and the second baffle plate 512 avoids the second air inlet 12a to open the second air inlet 12a.

[0070] Obviously, by separately arranging the switch connecting port 140 and the switch second air inlet 12a, it is helpful to reduce the requirements on the movement mode and movement range of the switching member 51, and facilitate the arrangement of the switching member 51.

[0071] It is understandable that, in the second direction, the relative positions of the first shielding plate 511 and the second shielding plate 512 can be specifically set according to the positions of the connecting port 140, the second air inlet 12a, etc. For example, the first shielding plate 511 is connected to the lower portion of the second shielding plate 512, so that a groove is defined between the first shielding plate 511 and the two second shielding plates 512.

[0072] For example, in Figure 6 , Fig. 9 and Fig.11In the example, the left and right sides of the connecting port 140 are respectively provided with second air inlets 12a, each second air inlet 12a includes one or more sub-outlets 12c, the opening 512a includes one or more sub-openings 512b, and each sub-opening 512b can be set corresponding to a sub-outlet 12c to realize the switching of the corresponding sub-outlet 12c; taking the example that the second air inlet 12a includes multiple sub-outlets 12c, the multiple sub-outlets 12c can be arranged at intervals along the second direction, and the multiple sub-openings 512b are also arranged at intervals along the second direction. In the first state, each sub-opening 512b is misaligned with the corresponding sub-outlet 12c, thereby closing the sub-outlet 12c, and in the second state, each sub-opening 512b is opposite to the corresponding sub-outlet 12c, thereby opening the sub-outlet 12c.

[0073] In some embodiments, Figure 3 , Fig. 9 and Fig.11 As shown, an air outlet assembly 6 is provided at the second air outlet 12b, and the air outlet assembly 6 includes an air outlet frame 61 and an air outlet bracket 62. The air outlet frame 61 and the air outlet bracket 62 define an installation cavity 60, and the second wind wheel component 4 is provided in the installation cavity 60, and the second wind wheel component 4 is installed on the air outlet bracket 62. Therefore, the air outlet assembly 6 can provide an installation space for the second wind wheel component 4, play a certain protective role for the second wind wheel component 4, and at the same time, the second wind wheel component 4 is isolated from the user, which is conducive to improving the compactness of the arrangement of various components in the second air duct 12, saving the occupied space of the second air duct 12, and thus saving the occupied space of the air conditioner indoor unit 100.

[0074] For example, in Figure 4 and Figure 5 In the example, the air outlet frame 61 is matched with the second air outlet 12b, and the air outlet bracket 62 is arranged on the upstream side of the air outlet frame 61. Optionally, the air outlet frame 61 may include a frame body and a grille, the frame body is matched with the second air outlet 12b, and the grille is arranged on one axial side of the second air duct component 4 to play a protective role.

[0075] Of course, the second wind wheel component 4 can also be arranged at other positions in the second air duct 12, as long as it is ensured that the second wind wheel component 4 can drive the airflow in the second air duct 12 to blow out from the second air outlet 12b.

[0076] In some embodiments, Figure 3-Figure 5 As shown, the housing component 1 includes a housing 13 and a partition 14, the partition 14 is arranged in the housing 13 to divide the internal space of the housing 13 into a first air duct 11 and a second air duct 12, and the communication port 140 is formed on the partition 14. Thus, the housing component 1 is easily assembled and the first air duct 11 and the second air duct 12 are easily formed.

[0077] In the above technical solution, the space formed by the first air duct 11 and the second air duct 12 is at least part of the internal space of the shell 13, that is, the space formed by the first air duct 11 and the second air duct 12 can be the entire internal space of the shell 13, or the space formed by the first air duct 11 and the second air duct 12 can be part of the internal space of the shell 13.

[0078] It is understandable that the specific structure of the partition 14 can be specifically set according to the shapes of the first air duct 11 and the second air duct 12 .

[0079] In some embodiments, Figure 3 As shown, the heat exchange component 2 is arranged opposite to the partition 14, and the heat exchange component 2 is arranged inclined relative to the partition 14, and the portion of the partition 14 opposite to the heat exchange component 2 is protruded toward the second air duct 12, so that the partition 14 can free up more arrangement space for the heat exchange component 2, which is conducive to appropriately increasing the inclination degree of the heat exchange component 2 relative to the partition 14, thereby increasing the heat exchange area.

[0080] For example, in Figure 3 In the example, the heat exchange component 2 and the partition 14 are arranged opposite to each other in the front-to-back direction, the partition 14 is arranged approximately vertically, the heat exchange component 2 is arranged inclined from top to bottom, and the distance between the heat exchange component 2 and the partition 14 in the front-to-back direction can be reduced in the up-down direction and in the direction away from the first air outlet 11b; for example, the heat exchange component 2 is arranged on the rear side of the partition 14, and the first air outlet 11b is located on the upper side of the partition 14, the distance between the heat exchange component 2 and the partition 14 in the front-to-back direction can be reduced from top to bottom, and the lower end of the heat exchange component 2 is lower than the lower edge of the connecting port 140, so as to ensure that the airflow passes through the heat exchange component 2 first and then flows to the connecting port 140.

[0081] Optionally, in Fig.13 In the example, the partition 14 may include a first part 144, a second part 145 and a third part 146, the first part 144 is arranged opposite to the heat exchange component 2, the first part 144 protrudes in the direction away from the heat exchange component 2, the second part 145 and the third part 146 are respectively arranged at opposite ends of the first part 144, and the second part 145 and the third part 146 can both extend in a direction perpendicular to the arrangement direction of the first part 144 to be connected to the shell 13.

[0082] In some embodiments, Figure 3 and Fig.13As shown, the connecting port 140 is respectively provided with second air inlet 12a on both sides in the first direction, and the portion of the partition 14 opposite to the heat exchange component 2, such as the first portion 144 mentioned above, includes a central portion 144a and an edge portion 144b, and the central portion 144a is respectively provided with edge portions 144b on both sides in the first direction, and the edge portions 144b are arranged corresponding to the second air inlet 12a, and each edge portion 144b extends in a direction close to the central portion 144b and in a direction away from the heat exchange component 2, so that the portion of the partition 14 opposite to the heat exchange component 2 is protruded in a direction away from the heat exchange component 2, and at the same time, the edge portion 144b can have a certain guiding effect on the airflow flowing from the corresponding second air inlet 12a to the second air duct 12.

[0083] For example, in Figure 3 and Fig.13 In the example, the partition 14 is arranged on the front side of the heat exchange component 14, and the second air inlet 12a is respectively provided on the left and right sides of the connecting port 140, and the two edge portions 144b are respectively provided on the left and right sides of the center portion 144a, and the center portion 144a and the edge portions 144b are both roughly formed as a flat plate structure, and each edge portion 144b extends from the center portion 144a toward a direction away from the center portion 144a and from front to rear to be connected with the shell 13, so that each edge portion 144b is arranged opposite to the corresponding second air inlet 12a on the left and right.

[0084] In some embodiments, Fig. 9 , Fig.11 and Fig.13 As shown, the partition 14 includes a partition portion 141 and a limiting portion 142, a connecting port 140 is formed on the partition portion 141, and the connecting port 140 can penetrate the partition portion 141 along the thickness direction of the partition portion 141, the limiting portion 142 is located on one side of the thickness of the partition portion 141, and the limiting portion 142 and the connecting port 140 are spaced apart, and an escape space 143 is defined between the limiting portion 142 and the partition portion 141, and the switching member 51 slides and cooperates in the escape space 143, so that the switching member 51 can be moved relative to the shell member 1, and at the same time, the partition 14 can play a certain limiting role in the movement of the switching member 51, thereby improving the stability of the movement of the switching member 51.

[0085] The limiting portion 142 is also formed with an escape opening 142a, which is in communication with the escape space 143; the switching component 5 also includes a driving device 52, which is connected to the switching member 51 through the escape opening 142a, so that the power of the driving device 52 can be transmitted to the switching member 51 to achieve the movement of the switching member 51. It can be seen that the setting of the escape opening 142a not only does not affect the power transmission of the driving device 52, but also facilitates the position of the driving device 52 to be more reasonable, which is conducive to making the distance between the position of the driving device 52 and the first position of the switching member 51 in the first state appropriate, and taking into account the distance between the position of the driving device 52 and the first position of the switching member 51 in the first state, so that the driving device 52 can meet the travel requirement of driving the switching member 51 to switch between the first state and the second state, and at the same time, the length of the switching member 51 in its moving direction will not be too long, saving materials and reducing costs.

[0086] Optionally, in Figure 3 , Fig. 9 and Fig.11 In the example, the driving device 52 may include a driving motor 521 and a transmission mechanism 522, and the driving motor 521 drives the switching member 51 to move through the transmission mechanism 522; the transmission mechanism 522 may be a gear 522a and a rack 522b mechanism, and the transmission mechanism 522 includes a gear 522a and a rack 522b, the gear 522a is connected to the driving motor 521 to be driven to rotate by the driving motor 521, the rack 522b is arranged on the switching member 51, and the rack 522b is arranged in the avoidance space 143, the gear 522a is arranged at the avoidance opening 142a, and the gear 522a is meshed with the gear 522a.

[0087] In some embodiments, Figure 3-Figure 5 , Fig. 9 and Fig.11 As shown, an air outlet frame 61 is provided at at least one of the first air outlet 11b and the second air outlet 12b. The air outlet frame 61 includes a frame body 611 and a grille 612. The frame body 611 is formed into an annular structure. The grille 612 is provided at one axial end of the frame body 611. The frame body 611 is movably matched with the shell part 1, and the frame body 611 can be rotated relative to the shell part 1 around at least one rotation axis to adjust the air outlet direction to better meet differentiated needs.

[0088] It can be seen that in the above technical solution, the frame 611 can guide the airflow corresponding to the first air outlet 11b or the second air outlet 12b to adjust the air outlet direction. When the frame 611 has multiple rotation axes, the rotation posture of the frame 611 is further enriched, and the air outlet direction of the air conditioner indoor unit 100 is enriched; for example, the multiple rotation axes can include a first rotation axis and a second rotation axis, the first rotation axis extends horizontally (including the first rotation axis extending absolutely horizontally, and the first rotation axis tilting at a small angle relative to the horizontal direction), and the second rotation axis extends vertically (including the second rotation axis extending absolutely vertically, and the second rotation axis tilting at a small angle relative to the vertical plane).

[0089] For example, in Fig. 9 and Fig.11 In the example of , the frame 611 can rotate relative to the housing part 1 around the rotation axis extending in the horizontal direction, so that the frame 611 can swing up and down to adapt to the cooling, heating and other modes of the air conditioner indoor unit 100. For example, when the air conditioner indoor unit 100 is used for cooling, the frame 611 can be rotated to an angle position for guiding air downward to improve the cooling efficiency of the air conditioner indoor unit 100; and when the air conditioner indoor unit 100 is used for heating, the frame 611 can be rotated to an angle position for guiding air upward to improve the heating efficiency of the air conditioner indoor unit 100.

[0090] Furthermore, at least one of the first air outlet 11b and the second air outlet 12b is also provided with an air outlet bracket 62, which is arranged on the upstream side of the air outlet frame 61, and the air outlet bracket 62 and the air outlet frame 61 define an installation cavity 60, and the second wind wheel component 4 is arranged in the installation cavity 60 and installed on the air outlet bracket 62. When the air outlet frame 61 rotates relative to the shell component 1, it will drive the second wind wheel component 4 and the air outlet bracket 62 to rotate together, so as to change the air outlet direction of the second wind wheel component 4, and at the same time cooperate with the guiding effect of the frame 611 on the airflow, so as to better adjust the air outlet direction.

[0091] For example, in Figure 1 In the example of , the second air outlet 12b is provided with an air outlet frame 61, and the first air outlet 11b is not provided with an air outlet frame 61. Figure 1 In the example, the first air outlet 11b is provided with an air guide component 7 to adjust the air outlet direction; the air guide component 7 may include a plurality of air guide plates arranged at intervals.

[0092] According to the control method of the air-conditioning indoor unit 100 of the second embodiment of the present invention, the air-conditioning indoor unit 100 has a plurality of air outlets, the plurality of air outlets include at least one first air outlet 11b and at least one second air outlet 12b, and each air outlet is used for blowing airflow.

[0093] like Fig.14As shown, the control method includes the following steps: if it is determined that the absolute value of the difference between the set temperature of the air-conditioning indoor unit 100 and the ambient temperature reaches the set threshold, the air-conditioning indoor unit 100 switches to the first mode, otherwise, the air-conditioning indoor unit 100 switches to the second mode. In the first mode, all air outlets are used to blow heat exchange airflow, and in the second mode, the first air outlet 11b is used to blow heat exchange airflow, and the second air outlet 12b is used to blow non-heat exchange airflow. "Heat exchange airflow" can refer to airflow that has undergone heat exchange with the heat exchange component 2 of the air-conditioning indoor unit 100, and "non-heat exchange airflow" can refer to airflow that has not undergone heat exchange with the heat exchange component 2 of the air-conditioning indoor unit 100.

[0094] It can be seen that in the first mode, the airflow blown out of all the air outlets is the airflow after heat exchange with the heat exchange component 2, so as to quickly cool down; while in the second mode, the airflow blown out of a part of the air outlets is the airflow after heat exchange with the heat exchange component 2, and the airflow blown out of another part of the air outlet has not exchanged heat with the heat exchange component 2, so as to play the role of circulating the air in the environment, so as to keep the ambient temperature basically constant, thereby improving the practicality and comfort of the air-conditioning indoor unit 100.

[0095] It is understandable that the above judgments can be made sequentially at regular intervals.

[0096] According to the control method of the air-conditioning indoor unit 100 of the embodiment of the present invention, if it is determined that the absolute value of the difference between the set temperature of the air-conditioning indoor unit 100 and the ambient temperature reaches a set threshold, the first mode of operation is switched to quickly adjust the ambient temperature, otherwise the second mode of operation is switched to keep the ambient temperature basically constant.

[0097] According to the control method of the air conditioner indoor unit 100 of the third aspect of the present invention, Fig.15 As shown, the air-conditioning indoor unit 100 is the air-conditioning indoor unit 100 according to the first embodiment of the present invention, and the control method may include the following steps: if it is determined that the absolute value of the difference between the set temperature of the air-conditioning indoor unit 100 and the ambient temperature reaches a set threshold, the switching component 5 switches to the first state; otherwise, the switching component 5 switches to the second state.

[0098] It can be seen that when the switching component 5 is switched to the first state, the airflows blown out of the first air duct 11 and the second air duct 12 are both airflows after heat exchange with the heat exchange component 2, so as to quickly cool down; when the switching component 5 is switched to the second state, the airflow blown out of the first air duct 11 is the airflow after heat exchange with the heat exchange component 2, and the airflow blown out of the second air duct 12 has not exchanged heat with the heat exchange component 2. The second air duct 12 can play the role of circulating the air in the environment, so as to keep the ambient temperature basically constant, thereby improving the practicality and comfort of the air-conditioning indoor unit 100.

[0099] It is understandable that the above judgments can be made sequentially at regular intervals.

[0100] According to the control method of the air-conditioning indoor unit 100 of the embodiment of the present invention, when it is determined that the absolute value of the difference between the set temperature of the air-conditioning indoor unit 100 and the ambient temperature reaches a set threshold, the switching component 5 switches to the first state to quickly adjust the ambient temperature, otherwise the switching component 5 switches to the second state to keep the ambient temperature basically constant.

[0101] Exemplarily, when the air-conditioning indoor unit 100 is used for cooling, it can be determined whether the difference between the ambient temperature and the set temperature of the air-conditioning indoor unit 100 reaches a set threshold. If so, the switching component 5 switches to the first state; when the air-conditioning indoor unit 100 is used for heating, it can be determined whether the difference between the set temperature of the air-conditioning indoor unit 100 and the ambient temperature reaches a set threshold. If not, the switching component 5 switches to the second state.

[0102] In the present application, the threshold value may be set according to actual needs, for example, the threshold value may be set to 2°C, 1.5°C, or 1°C, but is not limited thereto.

[0103] An air conditioner according to an embodiment of a fourth aspect of the present invention comprises the air conditioner indoor unit 100 according to the embodiment of the first aspect of the present invention.

[0104] The air conditioner according to the embodiment of the present invention can quickly adjust the ambient temperature by adopting the above-mentioned air conditioner indoor unit 100, and can also keep the ambient temperature basically constant, which has good practicality.

[0105] In the solution of the present application, there is no specific limitation on the type of the air conditioner and the type of the air conditioner indoor unit 100. For example, if the air conditioner indoor unit 100 is a floor-standing air conditioner indoor unit, the air conditioner is a floor-standing air conditioner, and if the air conditioner indoor unit 100 is a wall-mounted air conditioner indoor unit, the air conditioner is a wall-mounted air conditioner; but the present invention is not limited thereto.
