Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to an indoor unit of an air conditioner. Background Art

[0002] An air conditioner refers to a device that uses artificial means to adjust and control parameters such as the temperature, humidity, and flow rate of the air in the environment of a building or structure. An air conditioner usually has an indoor unit and an outdoor unit. Currently, the indoor unit of an air conditioner realizes the purification of indoor air by adding a purification module, such as a formaldehyde removal filter, on its air inlet side.

[0003] However, adding a purification module on the air inlet side of the indoor unit of an air conditioner will increase the air resistance, resulting in a decrease in the circulating air volume of the indoor unit of the air conditioner, and thus causing a decrease in the heat exchange efficiency of the indoor unit of the air conditioner. Moreover, the purification module is generally fixed and cannot move freely on the air inlet side of the indoor unit of the air conditioner, and users cannot adjust the purification efficiency and the heat exchange efficiency of the indoor unit of the air conditioner according to their own needs, making it difficult to meet the personalized needs of users.

[0029] Compared with the prior art, the beneficial effects of an indoor unit of an air conditioner according to an embodiment of the present invention are as follows:

[0030] By providing a plurality of first ventilation holes penetrating along the thickness direction on the first air deflector and providing purification coatings on the inner side of the first air deflector and the inner walls of the first ventilation holes, when the first air deflector closes the indoor air outlet, the air introduced into the indoor unit of the air conditioner can pass through the first ventilation holes and be output from the indoor air outlet to the room, and the output air can contact the purification coatings on the inner side of the first air deflector and the inner walls of the first ventilation holes, so that the air output from the indoor air outlet can be fully purified, and the purification efficiency of the indoor unit of the air conditioner is improved. And, the purification coatings can move relative to the indoor air outlet as the first air deflector rotates. After the first air deflector is opened, the circulating air volume of the indoor unit of the air conditioner can increase, so that the heat exchange efficiency of the indoor unit of the air conditioner is improved. In this way, the user can control the movement of the first air deflector according to his own needs, so as to adjust the purification efficiency and heat exchange efficiency of the indoor unit of this air conditioner and meet the personalized use needs of the user.

[0031] Moreover, the indoor unit of the air conditioner of the present application is provided with a wind guiding assembly having a first wind guiding plate and a second wind guiding plate at the indoor air outlet. Combining that both the first wind guiding plate and the second wind guiding plate can rotate independently relative to the housing, in this way, the indoor air outlet of the indoor unit of this air conditioner can form four-level control of no occlusion, only the first wind guiding plate occlusion, only the second wind guiding plate occlusion, and double occlusion of the first wind guiding plate and the second wind guiding plate, so as to be able to flexibly adjust the air volume of the indoor air outlet. And, the indoor unit of the air conditioner of the present application is provided with a plurality of first ventilation holes penetrating in the thickness direction on the first wind guiding plate of the wind guiding assembly. By providing a purification coating on the inner side of the first wind guiding plate and the inner wall of the first ventilation holes, the air flow flowing out through the indoor air outlet can be purified by the purification coating of the first wind guiding plate. Moreover, since the purification coating is provided on the first wind guiding plate, its position relative to the indoor air outlet can be flexibly adjusted. Combining the aforementioned four-level control gears, the indoor unit of this air conditioner can realize the adjustment of the purification efficiency and the heat exchange efficiency, meeting the personalized usage needs of users.

[0032] Moreover, the indoor unit of the air conditioner of the present application is provided with a plurality of second ventilation holes penetrating in the thickness direction on the second wind guiding plate, and a purification coating is provided on the inner side of the second wind guiding plate and the inner wall of the second ventilation holes. In this way, the air flow flowing out through the indoor air outlet can be purified by the purification coating of the first wind guiding plate or the second wind guiding plate. Moreover, since the purification coating is provided on the first wind guiding plate and the second wind guiding plate, its position relative to the indoor air outlet can be flexibly adjusted. Combining the aforementioned four-level control gears, the adjustment of the purification efficiency and the heat exchange efficiency can be further realized, meeting the personalized usage needs of users.

[0033] And, by adjusting the structures and positional layouts of the first ventilation holes and the second ventilation holes in the present application, when both the first wind guiding plate and the second wind guiding plate are closed at the indoor air outlet, the central axis of the first ventilation hole and the central axis of the adjacent second ventilation hole are parallel to each other or form an included angle α in the projection on the longitudinal section, and the included angle α satisfies 0° < α < 20°. In this way, the first ventilation holes and the second ventilation holes can be generally arranged along the air flow direction, and the resistance of the air blown into the room through the indoor air outlet passing through the first ventilation holes and the second ventilation holes in sequence is smaller, which can effectively increase the air volume of the indoor unit of the air conditioner under double occlusion.

Detailed implementation manners

[0057] The following will further describe in detail the specific implementation manners of the present application in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0058] In the description of the present application, it should be understood that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element. The terms "mounted", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0059] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "height", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. in the present application is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0060] In the description of the present application, it should be understood that the terms "first" and "second" used in the present application are only for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0061] In this application, the air conditioner performs the refrigeration cycle or the heating cycle through a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle and the heating cycle include a series of processes such as compression, condensation, expansion, and evaporation, and provide cooling capacity or heat to the indoor space by the endothermic or exothermic of the refrigerant, thereby regulating the temperature of the indoor space.

[0062] The compressor compresses the refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0063] The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve the refrigeration effect by heat-exchanging with the material to be cooled by utilizing the latent heat of evaporation of the refrigerant. Throughout the cycle, the air conditioner can regulate the temperature of the indoor space.

[0064] The air conditioner of the present application includes an indoor unit of the air conditioner and an outdoor unit of the air conditioner. Among them, the outdoor unit of the air conditioner includes a compressor and an outdoor heat exchanger, and the indoor unit of the air conditioner includes an indoor heat exchanger. According to the application scenario of the air conditioner, the expansion valve can be provided in the indoor unit of the air conditioner or the outdoor unit of the air conditioner.

[0065] The indoor heat exchanger and the outdoor heat exchanger can be used as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the outdoor heat exchanger is an evaporator, and the air conditioner is used as a heater in the heating mode; when the indoor heat exchanger is used as an evaporator, the outdoor heat exchanger is a condenser, and the air conditioner is used as a cooler in the refrigeration mode.

[0066] Embodiment 1

[0067] The following refers to Figures 1 - 5 Describe the indoor unit 110 of the air conditioner according to the embodiment of the present application. The indoor unit of the air conditioner in this embodiment includes a housing 1. An indoor air inlet 2 is provided at the top of the housing 1, and an indoor air outlet 3 is provided at the bottom of the housing 1. Moreover, a filter screen (not shown in the figure) is provided at the indoor air inlet 2 to filter the air introduced into the housing 1; a wind guiding assembly 8 is provided at the indoor air outlet 3 to guide the direction of the air flow blowing into the room.

[0068] A fan 5 is arranged inside the housing 1. The fan 5 is configured to introduce the air outside the housing 1 from the indoor air inlet 2 into the housing 1, and under the driving of the operation of the fan 5, the introduced air is output to the room. In this embodiment, the fan 5 is a turbine fan.

[0069] An air duct member 7 is further arranged inside the housing 1. The air duct member 7 is arranged on the outer peripheral side of the fan 5 and is at the output end of the fan 5 to guide the air output by the fan 5 to the indoor air outlet 3. It can be understood that the main function of the air duct member 7 is to cooperate with the housing 1 to form an air duct. The air duct member 7 is generally configured with a curved structure to be adapted to the air flow output by the fan 5.

[0070] Reference Figures 3 - 5 , the air guiding assembly 8 of this embodiment is arranged at the indoor air outlet 3 to guide the air output to the room to flow in a specified direction. The black arrow in the figure indicates the air flow direction. Generally, a motor (not shown in the figure) is arranged inside the housing 1 to drive the air guiding assembly 8 to rotate relative to the housing 1. As the rotation angle of the air guiding assembly 8 relative to the housing 1 changes, the air guiding assembly 8 can guide the air output to the room to different directions.

[0071] Reference Figures 3 - 4 , the air guiding assembly 8 includes a first air guiding plate 80. Among them, the first air guiding plate 80 can independently rotate relative to the housing 1 to open and close the indoor air outlet 3. Since the air guiding assembly 8 of this Embodiment 1 only has one air guiding plate, that is, the first air guiding plate 80, the first air guiding plate 80 can be configured according to the specifications of the indoor air outlet 3, so that when the first air guiding plate 80 is closed, it can completely block or nearly completely block the indoor air outlet 3.

[0072] A plurality of first ventilation holes 84 penetrating in the thickness direction are arranged on the first air guiding plate 80, and a purification coating 86 is arranged on the inner side of the first air guiding plate 80 and the inner wall of the first ventilation holes 84.

[0073] It can be understood that the purification coating 86 can be configured according to the user's needs. For example, the purification coating 86 can be used for removing formaldehyde, removing VOCs, removing odors, etc. Taking the removal of formaldehyde as an example, the purification coating 86 can select a catalyst coating prepared from manganese oxides. This type of catalyst can catalytically oxidize formaldehyde molecules at room temperature and decompose them into carbon dioxide and water. In addition, this type of catalyst is sensitive to heat. When the surface temperature of the catalyst increases, its catalytic decomposition activity for formaldehyde can be improved. Moreover, since this type of catalyst has no loss during the reaction process, this type of catalyst can maintain a long-term formaldehyde removal ability. At the same time, based on its heat-sensitive characteristics, this type of catalyst can utilize the heat generated during the heating of the air conditioner 100 to exhibit higher catalytic oxidation activity. Of course, according to the user's usage requirements, the purification coating 86 can select other existing catalyst coatings, which will not be elaborated here.

[0074] Since the first air deflector 80 can rotate independently relative to the housing 1 to open and close the indoor air outlet 3, based on the state of the first air deflector 80, the indoor unit 110 of the air conditioner in this Embodiment 1 can be at least divided into two control scenarios:

[0075] Reference Figure 3 , when the first air deflector 80 is closed, the first air deflector 80 blocks the indoor air outlet 3, and the air output by the fan 5 flows out through the first ventilation holes 84 from the inner side of the first air deflector 80. During this process, the air can contact the purification coating 86 on the first air deflector 80 and the first ventilation holes 84 to achieve purification.

[0076] Reference Figure 5 , when the first air deflector 80 is open, the air output by the fan 5 directly flows out of the indoor air outlet 3. At this time, the air flowing out of the indoor air outlet 3 has no contact with the purification coating 86 of the first air deflector 80. Therefore, this control scenario can be a non-purification mode. Of course, when the first air deflector 80 is open, the purification coating 86 of the first air deflector 80 can still contact the indoor air to purify the indoor air, but the air purification efficiency is relatively low.

[0077] Embodiment 2

[0078] The difference between this Embodiment 2 and Embodiment 1 is that, referring to Figures 1 - 2 , Figures 6 - 7, in the second embodiment, the air guiding assembly 8 includes two air guiding plates, namely the first air guiding plate 80 and the second air guiding plate 81. Among them, the first air guiding plate 80 can independently rotate relative to the housing 1 to open and close the indoor air outlet 3. In order to enable the first air guiding plate 80 to rotate relative to the housing 1, as an example of this embodiment, a first connecting seat 82 can be provided inside the housing 1, and the first connecting seat 82 extends from the housing 1 into the air duct. The first air guiding plate 80 is rotatably connected to the first connecting seat 82, so that the first air guiding plate 80 can rotate in the air duct to guide the air output by the fan 5.

[0079] The position where the first connecting seat 82 is provided is opposite to the air duct member 7. In this way, the first air guiding plate 80 and the air duct member 7 will be relatively arranged near the indoor air outlet 3. Moreover, when the first air guiding plate 80 rotates from the closed state to the open state, the first air guiding plate 80 will rotate towards the inside of the indoor air outlet 3, so that the outer side of the first air guiding plate 80 rotates towards the air duct member 7, while the inner side of the first air guiding plate 80 rotates towards the housing 1, thereby forming a passage 4 for air to pass through between the outer side of the first air guiding plate 80 and the air duct member 7.

[0080] It should be noted that the inner side of the indoor air outlet 3 refers to the side of the indoor air outlet 3 facing the inside of the housing 1. In contrast, the outer side of the indoor air outlet 3 refers to the side of the indoor air outlet 3 facing the room.

[0081] It can be understood that under the combined action of the fan 5 and the air duct member 7, most of the air output by the fan 5 will be concentrated near the air duct member 7 under the action of centrifugal force. The first air guiding plate 80 and the air duct member 7 are relatively arranged, which can ensure that when the first air guiding plate 80 is opened, the first air guiding plate 80 no longer affects the air duct area near the air duct member 7, ensuring that the air output by the fan 5 can smoothly pass through the area where the first air guiding plate 80 is located and guaranteeing the air volume when the first air guiding plate 80 is in the open state.

[0082] Reference Figures 6 - 7 , the second air guiding plate 81 is provided on the outer side of the first air guiding plate 80 and can independently rotate relative to the housing 1 to open and close the indoor air outlet 3. As an example of this embodiment, a second connecting seat 83 can be provided inside the housing 1, and the second connecting seat 83 extends from one side of the air duct member 7 to the indoor air outlet 3. The second air guiding plate 81 is rotatably connected to the second connecting seat 83, so that the second air guiding plate 81 can rotate relative to the indoor air outlet 3 to guide the air output by the fan 5.

[0083] It can be understood that since the first air deflector 80 is arranged inside the second air deflector 81, if the second air deflector 81 rotates towards the inside of the indoor air outlet 3, it is likely to interfere with the first air deflector 80. Therefore, the second air deflector 81 generally rotates towards the outside of the indoor air outlet 3. By adjusting the rotation angle of the second air deflector 81, the second air deflector 81 can completely leave the area where the indoor air outlet 3 is located, so as to ensure the air volume when the second air deflector 81 is in the open state. Of course, the second air deflector 81 is arranged outside the first air deflector 80, and in the closed state, it should be able to block the indoor air outlet 3 so that the air deflector assembly 8 can block the indoor air outlet 3.

[0084] Moreover, since the rotation centers of the first air deflector 80 and the second air deflector 81 are arranged oppositely, when the first air deflector 80 rotates relative to the housing 1, it may interfere with the second connecting seat 83. Therefore, the first air deflector 80 can avoid the second connecting seat 83 as appropriate, so that the air deflector assembly 8 can be arranged more compactly.

[0085] Reference Figures 6 - 7 、 Figures 12 - 14 As shown in FIGS.

[0086] Since the first air deflector 80 can rotate independently relative to the housing 1 to open and close the indoor air outlet 3, based on the state of the first air deflector 80, the indoor unit 110 of the air conditioner in Embodiment 2 can be at least divided into two control scenarios:

[0087] Reference Figure 6 As shown in FIGS.

[0088] Reference Figure 7 As shown in FIGS.

[0089] Embodiment 3

[0090] The difference between this Embodiment 3 and Embodiment 2 is that, as shown in FIGS. Figures 1 - 2 、 Figures 8 - 21, in Embodiment 3, in addition to providing a purification coating 86 on the first air deflector 80, the second air deflector 81 is also provided with a purification coating 86, enabling the indoor unit 110 of this air conditioner to adjust its operation more flexibly. Refer to Figures 5 - 12 , a plurality of second ventilation holes 85 penetrating in the thickness direction are provided on the second air deflector 81, and purification coatings 86 are provided on the inner side of the second air deflector 81 and the inner walls of the second ventilation holes 85.

[0091] Since both the first air deflector 80 and the second air deflector 81 can rotate independently relative to the housing 1 to open and close the indoor air outlet 3, based on the states of the first air deflector 80 and the second air deflector 81, the indoor unit 110 of this air conditioner can be divided into at least four control scenarios: one is that the first air deflector 80 is closed and the second air deflector 81 is open; the second is that the first air deflector 80 is open and the second air deflector 81 is closed; the third is that the first air deflector 80 is open and the second air deflector 81 is open; the fourth is that the first air deflector 80 is closed and the second air deflector 81 is closed.

[0092] Refer to Fig. 11. When the first air deflector 80 is closed and the second air deflector 81 is open, the first air deflector 80 blocks the indoor air outlet 3, and the second air deflector 81 leaves the area where the indoor air outlet 3 is located. The air output by the blower 5 flows out from the inner side of the first air deflector 80 through the first ventilation holes 84. During this process, the air can contact the purification coatings 86 on the first air deflector 80 and the first ventilation holes 84 to achieve purification.

[0093] Refer to Figure 8 , when the first air deflector 80 is open and the second air deflector 81 is closed, a passage 4 for air to pass through is formed between the outer side of the first air deflector 80 and the air duct member 7. The second air deflector 81 blocks the indoor air outlet 3. The air output by the blower 5 flows from the passage 4 to the inner side of the second air deflector 81 and flows out from the inner side of the second air deflector 81 through the second ventilation holes 85. During this process, the air can contact the purification coatings 86 on the second air deflector 81 and the second ventilation holes 85 to achieve purification.

[0094] Refer to Figure 9 , when the first air deflector 80 is open and the second air deflector 81 is open, a passage 4 for air to pass through is formed between the outer side of the first air deflector 80 and the air duct member 7. The second air deflector 81 leaves the area where the indoor air outlet 3 is located. The air output by the blower 5 directly flows out of the indoor air outlet 3 from the passage 4. At this time, the air volume output by the indoor unit 110 of the air conditioner is the largest, but the air purification efficiency is relatively low.

[0095] Refer to Figure 10, when the first air deflector 80 is closed and the second air deflector 81 is closed, the first air deflector 80 blocks the indoor air outlet 3, and the second air deflector 81 blocks the indoor air outlet 3. The air output by the blower 5 needs to pass through the inner side of the first air deflector 80 → the first ventilation hole 84 → the inner side of the second air deflector 81 → the second ventilation hole 85 in sequence before it can flow out of the indoor air outlet 3. At this time, the air volume of the indoor unit 110 of the air conditioner is the smallest, but the air purification efficiency is relatively the highest.

[0096] Of course, according to the user's usage requirements, when the first air deflector 80 and the second air deflector 81 are opened and closed, they can also have multiple rotation angles. For example, if the first air deflector 80 can be switched to the open state by rotating 90° from the closed state, then the first air deflector 80 can also be rotated 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80° from the closed state, or adjusted between 0 and 90° based on stepless control. In this way, the indoor unit 110 of this air conditioner can have multiple air outlet / purification gear configurations. By controlling the rotation angles of the first air deflector 80 and the second air deflector 81, the blocking effects of the first air deflector 80 and the second air deflector 81 are adjusted, so that the air output by the blower 5 can fully contact the purification coating 86, realizing indoor air purification.

[0097] Moreover, by configuring different rotation angles for the first air deflector 80 and the second air deflector 81, they can form different blocking combinations, so as to further adjust the purification efficiency and heat exchange efficiency of the indoor unit 110 of the air conditioner, providing the user with multiple gear selections of operating modes to meet the user's personalized usage requirements. In this way, the user can select the appropriate operating mode gear according to their own preferences, needs and usage scenarios.

[0098] It can be understood that both the contact area between the air and the purification coating 86 and the flow time of the air on the purification coating 86 will affect the purification efficiency of the purification coating 86 for the air. Therefore, parameters such as the shapes and sizes of the first air deflector 80, the second air deflector 81, the first ventilation hole 84, and the second ventilation hole 85 can be designed to improve the coating effect of the purification coating 86 inside the first ventilation hole 84 and the second ventilation hole 85 and the flow time of the air in the first ventilation hole 84 and the second ventilation hole 85, so as to improve the purification efficiency and heat exchange efficiency of the indoor unit 110 of the air conditioner.

[0099] As an example of this embodiment, the thickness of the first air deflector 80 can be set within the range of 2 to 5 mm, and the thickness of the second air deflector 81 can be set within the range of 2 to 5 mm. Also, the aperture diameter of the first ventilation hole 84 can be set within the range of 2 to 5 mm, and the aperture diameter of the second ventilation hole 85 can be set within the range of 2 to 5 mm. Moreover, the cross-sectional shape of the first ventilation hole 84 is any one of a circle, an ellipse, or a polygon; the cross-sectional shape of the second ventilation hole 85 is any one of a circle, an ellipse, or a polygon.

[0100] It can be understood that the thickness of the first air deflector 80 is closely related to the length of the first ventilation hole 84, and the thickness of the second air deflector 81 is closely related to the length of the second ventilation hole 85. Changing the thicknesses of the first air deflector 80 and the second air deflector 81 can change the flow time of air in the first ventilation hole 84 and the second ventilation hole 85, thereby changing the air purification efficiency. And changing the aperture diameters and shapes of the first ventilation hole 84 and the second ventilation hole 85 can change the total coating area of the purification coating 86 and also change the air volume output of the indoor unit 110 of the air conditioner. By controlling the aperture diameters of the first ventilation hole 84 and the second ventilation hole 85, the total coating area of the purification coating 86 can be preferably increased and the indoor unit 110 of the air conditioner can have a suitable air volume output, so that the indoor unit 110 of the air conditioner can obtain a better purification effect and ensure the refrigeration and heating efficiency.

[0101] As an example of this embodiment, referring to Figure 18 , Figure 19 , the inner aperture diameter D 内1 of the first ventilation hole 84 is greater than or equal to the outer aperture diameter D 外1 of the first ventilation hole 84, and, the inner aperture diameter D 内2 of the second ventilation hole 85 is greater than or equal to the outer aperture diameter D 外 2.

[0102] It should be noted that the inner aperture diameter D 内1 of the aforementioned first ventilation hole 84 refers to the aperture diameter of the first ventilation hole 84 inside the first air deflector 80, and the outer aperture diameter D 外1 of the aforementioned first ventilation hole 84 refers to the aperture diameter of the first ventilation hole 84 outside the first air deflector 80. Similarly, the inner aperture diameter D 内2 of the second ventilation hole 85 refers to the aperture diameter of the second ventilation hole 85 inside the second air deflector 81, and the outer aperture diameter D 外2 of the second ventilation hole 85 refers to the aperture diameter of the second ventilation hole 85 outside the second air deflector 81.

[0103] Since the air output by the blower 5 flows from the inner side to the outer side of the first ventilation hole 84 and from the inner side to the outer side of the second ventilation hole 85, in order to enable the air to come into contact with the purification coating 86 on the inner walls of the first ventilation hole 84 and the second ventilation hole 85 more fully, the aperture of the first ventilation hole 84 can gradually contract along the air flow direction, and the ratio of the inner aperture to the outer aperture of the first ventilation hole 84 is in the range of 1.1 to 2; and, the aperture of the second ventilation hole 85 can gradually contract along the air flow direction, and the ratio of the inner aperture to the outer aperture of the second ventilation hole 85 is in the range of 1.1 to 2.

[0104] As an example of this embodiment, the projected area of the first air deflector 80 in the thickness direction thereof is S 1 , and the projected area of the second air deflector 81 in the thickness direction thereof is S 2 , the total area of the indoor air outlet 3 is S, and, 0.6*S ≤ S 1 < S 2 , and 0.9*S ≤ S 2 ≤ S.

[0105] It can be understood that the projected area S of the first air deflector 80 1 will affect the proportion of the first air deflector 80 covering the indoor air outlet 3, and the projected area S of the second air deflector 81 2 will affect the proportion of the second air deflector 81 covering the indoor air outlet 3. Therefore, in order to enable the first air deflector 80 and the second air deflector 81 to effectively block the indoor air outlet 3 and restrict the air to flow through the first ventilation hole 84 of the first air deflector 80 and the second ventilation hole 85 of the second air deflector 81, the first air deflector 80 and the second air deflector 81 need to have a certain area. And, since the first air deflector 80 is arranged inside the second air deflector 81, in order to avoid interference between the first air deflector 80 and the second air deflector 81 and affect the normal rotation of the first air deflector 80, the area of the first air deflector 80 should not be greater than the area of the second air deflector 81. Moreover, the projected area of the first air deflector 80 being smaller than the projected area of the second air deflector 81 can also enable the indoor unit 110 of this air conditioner to have different air output volumes and purification efficiencies in two cases where the first air deflector 80 is closed and the second air deflector 81 is opened, and the first air deflector 80 is opened and the second air deflector 81 is closed, so that the operation mode of the indoor unit 110 of the air conditioner can have more choices.

[0106] In addition to the projected areas of the first air deflector 80 and the second air deflector 81, the areas of the first ventilation holes 84 and the second ventilation holes 85 will also affect the efficiency of air flowing out from the first air deflector 80 and the second air deflector 81. As an example of this embodiment, the sum of the areas of the plurality of first ventilation holes 84 may be 50% to 80% of the projected area of the first air deflector 80 in its thickness direction; and the sum of the areas of the plurality of second ventilation holes 85 may be 50% to 80% of the projected area of the second air deflector 81 in its thickness direction.

[0107] Increasing the sum of the areas of the first ventilation holes 84 and the sum of the areas of the second ventilation holes 85 is beneficial to increasing the total coating area of the purification coating 86 and the air volume, so that the indoor unit 110 of the air conditioner can obtain higher purification efficiency and cooling / heating rate. Of course, the sum of the areas of the first ventilation holes 84 and the sum of the areas of the second ventilation holes 85 will also affect the structural strength and blocking effect of the first air deflector 80 and the second air deflector 81 themselves. Therefore, the sum of the areas of the first ventilation holes 84 and the sum of the areas of the second ventilation holes 85 should not be too large, so that the structural strength and blocking effect of the first air deflector 80 and the second air deflector 81 can meet the performance requirements of the indoor unit 110 of the air conditioner.

[0108] It can be understood that changing the shapes of the first ventilation holes 84 and the second ventilation holes 85 will affect the coating area of the purification coating 86 and the air flow rate. Referring to Figure 18 , as an example of this embodiment, a plurality of first grooves 840 extending along the length direction are provided on the inner wall of the first ventilation hole 84, and the plurality of first grooves 840 are spaced apart on the inner wall of the first ventilation hole 84; and a plurality of second grooves 850 extending along the length direction are provided on the inner wall of the second ventilation hole 85, and the plurality of second grooves 850 are spaced apart on the inner wall of the second ventilation hole 85.

[0109] The shape designs of the first grooves 840 and the second grooves 850 can be diverse, and different shape designs will have different effects on the coating area of the purification and the air flow rate. As an example of this embodiment, the cross-sectional profiles of the first grooves 840 and the second grooves 850 are trapezoidal, and the long bottom sides of the trapezoids face the channels of the first ventilation holes 84; and the groove depth of the first grooves 840 is in the range of 0.1 to 0.5 mm, and the maximum groove width of the first grooves 840 is in the range of 0.2 to 1 mm; and the groove depth of the second grooves 850 is in the range of 0.1 to 0.5 mm, and the maximum groove width of the second grooves 850 is in the range of 0.2 to 1 mm.

[0110] It should be noted that the aforementioned maximum slot width is the width of the surface where the long base of the trapezoid is located. The aforementioned slot depth is the height of the trapezoid. The slot depth and the maximum slot width will affect the total area formed by the first groove 840 and the second groove 850. Therefore, these two parameters will also affect the coating area of the purification coating 86 and the air flow rate. Of course, for the specific numerical settings of these two parameters, it is necessary to balance the specifications of the first air deflector 80, the second air deflector 81, the first ventilation hole 84, and the second ventilation hole 85. For example, increasing the slot depth of the first groove 840 can increase the area of the purification coating 86 and the air outlet volume, thereby enhancing the air purification effect. However, increasing the slot depth will also cause a decrease in the structural strength of the first air deflector 80.

[0111] In addition, the position arrangement of the first ventilation hole 84 and the second ventilation hole 85 will also affect the air outlet volume and the air purification efficiency of the indoor unit 110 of the air conditioner. Refer to Figures 12 - 21 , as an example of this embodiment, multiple first ventilation holes 84 can be arranged in a rectangular array, and multiple second ventilation holes 85 can be arranged along the length direction of the second air deflector 81, and multiple rows of second ventilation holes 85 are staggered along the width direction of the second air deflector 81.

[0112] Moreover, the first ventilation hole 84 and the second ventilation hole 85 are staggered. When both the first air deflector 80 and the second air deflector 81 are closed at the indoor air outlet 3, the central axis of the first ventilation hole 84 and the central axis of the adjacent second ventilation hole 85 are parallel to each other or form an angle α in the projection on the longitudinal section, and the angle α satisfies 0° < α < 20°.

[0113] Of course, through the design optimization and / or opening angle adjustment of the first air deflector 80 and the second air deflector 81, when both the first air deflector 80 and the second air deflector 81 are closed at the indoor air outlet 3, the projection of the central axis of the first ventilation hole 84 and the central axis of the adjacent second ventilation hole 85 on the longitudinal section is close to parallel, which can minimize the resistance of the air passing through the first ventilation hole 84 and the second ventilation hole 85 in sequence, and is beneficial to increasing the air outlet volume of the indoor unit 110 of the air conditioner.

[0114] Based on the aforementioned indoor unit 110 of the air conditioner, some embodiments of the present application further provide an air conditioner 100. Refer to Figure 1 , the air conditioner 100 includes the aforementioned indoor unit 110 of the air conditioner and an outdoor unit 120. The outdoor unit 120 of the air conditioner has an outdoor heat exchanger (not shown in the figure), and the indoor unit 110 of the air conditioner has an indoor heat exchanger 6. The outdoor heat exchanger (not shown in the figure) is connected to the indoor heat exchanger 6 (not shown in the figure) to realize a heat exchange cycle.

[0115] Since the air conditioner 100 has the structure of the indoor unit 110 of the air conditioner described above, the air conditioner 100 also has the effects of the indoor unit 110 of the air conditioner described above.

[0116] In summary, the indoor unit 110 of the air conditioner provided by the embodiment of the present application is provided with a plurality of first ventilation holes 84 penetrating along the thickness direction on the first air deflector 80, and purification coatings 86 are provided on the inner side of the first air deflector 80 and the inner walls of the first ventilation holes 84. In this way, when the first air deflector 80 closes the indoor air outlet 3, the air introduced into the indoor unit 100 of the air conditioner can pass through the first ventilation holes 84 and be output to the room from the indoor air outlet 3. Moreover, the output air can contact the purification coating 86 on the inner side of the first air deflector 80 and the purification coating 86 on the inner wall of the first ventilation hole, so that the air output through the indoor air outlet 3 can be fully purified, and the purification efficiency of the indoor unit 100 of the air conditioner is improved. And the purification coating 86 can move relative to the indoor air outlet 3 as the first air deflector 80 rotates. After the first air deflector 80 is opened, the circulating air volume of the indoor unit 100 of the air conditioner can increase, so that the heat exchange efficiency of the indoor unit 100 of the air conditioner is improved. In this way, the user can control the movement of the first air deflector 80 according to his own needs, so as to adjust the purification efficiency and heat exchange efficiency of the indoor unit 100 of the air conditioner and meet the personalized use needs of the user.

[0117] Moreover, the indoor unit 100 of the air conditioner of the present application is provided with a wind guiding assembly 8 at the indoor air outlet 3, and a plurality of first ventilation holes 84 penetrating along the thickness direction are provided on the first air deflector 80 of the wind guiding assembly 8, and a plurality of second ventilation holes 85 penetrating along the thickness direction are provided on the second air deflector 81. Combining that both the first air deflector 80 and the second air deflector 81 can rotate independently relative to the housing 1, in this way, the indoor air outlet 3 of the indoor unit 110 of the air conditioner can form four control gears of unobstructed, only blocked by the first air deflector 80, only blocked by the second air deflector 81, and double blocked by the first air deflector 80 and the second air deflector 81, so that the air volume of the indoor air outlet 3 can be flexibly adjusted. And the indoor unit 110 of the air conditioner is provided with a purification coating 86 on the inner side of the first air deflector 80 and the inner walls of the first ventilation holes 84, and a purification coating 86 is provided on the inner side of the second air deflector 81 and the inner walls of the second ventilation holes 85, so that the airflow flowing out through the indoor air outlet 3 can be purified by the purification coating 86 of the first air deflector 80 or the second air deflector 81. Moreover, the purification coating 86 is provided on the first air deflector 80 and the second air deflector 81, and its position relative to the indoor air outlet 3 can be flexibly adjusted. Combining the above-mentioned four control gears, the indoor unit 110 of the air conditioner can adjust the purification efficiency and heat exchange efficiency to meet the personalized use needs of the user.

[0118] Moreover, the air conditioner 100 of the present application adjusts the structures and positional layouts of the first air vent 84 and the second air vent 85, so that when the first air deflector 80 and the second air deflector 81 are both closed at the indoor air outlet 3, the central axis of the first air vent 84 and the central axis of the adjacent second air vent 85 are parallel to each other or form an included angle α in the projection on the longitudinal section, and the included angle α satisfies 0° < α < 20°. In this way, the first air vent 84 and the second air vent 85 can be arranged generally along the air flow direction, and the air blown into the room through the indoor air outlet 3 passes through the first air vent 84 and the second air vent 85 in turn with less resistance, which can effectively increase the air output of the indoor unit 110 of the air conditioner under double occlusion.

[0119] The above are only the preferred embodiments of the present application. It should be noted that for those of ordinary skill in the art of this technology, without departing from the technical principle of the present application, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of the present application.
