Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to a window type air conditioner. Background Art

[0002] A window air conditioner is an air conditioner that can be installed on a wall with an installation opening (e.g., a window). A window air conditioner generally includes an indoor unit and an outdoor unit, wherein the indoor unit has an indoor air inlet and an indoor air outlet. Indoor air can flow into the indoor unit through the indoor air inlet, exchange heat with the indoor heat exchanger, and then flow into the room after being guided by an air guide plate at the indoor air outlet.

[0003] When air flows into the room from the indoor air outlet, affected by the wall effect, the airflow out of the indoor air outlet is not uniform, the velocity of the airflow located on the upper side of the indoor air outlet is higher than the velocity of the airflow located on the lower side of the indoor air outlet, the airflow located on the upper side of the indoor air outlet will rush downward and hit the wind guide plate arranged laterally at the indoor air outlet, causing the lateral wind guide plate to vibrate, resulting in more obvious surging sound and wind plate vibration sound. Utility Model Content

[0014] In some embodiments, the diverter is disposed at the upper portion of the first grille hole and connected to the top of the first grille hole, so that the airflow flowing out of the indoor air outlet is diverted to the lower area of ​​the first grille hole.

[0015] In some embodiments, the vertical length of the first grille hole is H, the vertical length of the diverter is Hd, and Hd is in the range of 0.3H to 0.5H.

[0016] In some embodiments, there are multiple flow dividers, and the multiple flow dividers are arranged in a row in the first grid holes along the transverse direction, and each flow divider is arranged in a one-to-one correspondence with each first grid hole.

[0017] In some embodiments, along the direction of air flow output to the indoor room through the indoor air outlet, the diverter is arranged on the right side of the air outlet grille and close to the edge of the air outlet grille; and the diverter leaves a space in the first grille hole on the far right, so that the first grille hole on the far right remains connected.

[0018] In some embodiments, the air outlet grille includes:

[0019] A grid frame, the grid frame is connected to the shell, and the grid frame is provided with an opening;

[0020] A plurality of transverse ribs, each of which is arranged in the opening along a transverse direction, and the plurality of transverse ribs are arranged in a vertical direction to divide the opening into a plurality of grille air ducts arranged in a transverse direction;

[0021] A plurality of first vertical ribs are provided, each of which is arranged between two adjacent transverse ribs along a vertical direction, and the plurality of first vertical ribs are arranged in a transverse direction to divide the grille air duct between two adjacent transverse ribs into a plurality of first grille holes.

[0022] In some embodiments, each transverse rib is configured to be arranged in a horizontal direction out of position with the air outlet guide plate, so that when the air outlet guide plate is rotated to a horizontal position, the air outlet guide plate and the transverse rib are not on the same horizontal plane.

[0026] In some embodiments, the air outlet grille further comprises:

[0027] A plurality of second vertical ribs are provided, each of which is arranged in the opening along a vertical extension, and each of which is between the transverse rib and the grille frame. The plurality of second vertical ribs are arranged in a transverse arrangement to divide the grille air duct between the transverse rib and the grille frame into a plurality of second grille holes.

[0028] Compared with the prior art, the window air conditioner implemented by the utility model has the following beneficial effects:

[0029] The window air conditioner of the present application introduces air outside the shell from the indoor air inlet into the inside of the shell through the centrifugal fan, and outputs it to the room through the indoor air outlet, so that the air output through the indoor air outlet is partially concentrated on the upper part of the indoor air outlet under the action of centrifugal force and blown to the air guide component. At the position where the air guide component corresponds to the concentrated air flow, a diverter is arranged in part of the first grille holes, and the diverter is used to block the air flow flowing out of the indoor air outlet and gathered at the upper part of the indoor air outlet, so that the air flow flows to the area not covered by the diverter, thereby diverting the air flow flowing out of the indoor air outlet Flow, breaks up the airflow blowing toward the area where the diverter is located, so that the airflow blowing toward the area where the diverter is located can flow along the diverter to the lower area corresponding to the first grille hole, thereby reducing the airflow rate in the area where the diverter is located, that is, the upper area of ​​the first grille hole, while the airflow rate in the area where the diverter is not set, that is, the lower area of ​​the first grille hole, increases, so that the airflow output through the air outlet grille is more uniform as a whole, and the air flow flowing out through the indoor air outlet will not form a large flow velocity difference on the upper and lower sides of the air outlet guide plate, thereby avoiding the surging sound and wind plate vibration sound caused by the vibration of the air outlet guide plate caused by the up and down movement of the airflow.

[0030] Furthermore, the window air conditioner of the present application arranges the position of the diverter based on the flow path of the airflow, so that the diverter is set on the right side of the air outlet grille and close to the edge of the air outlet grille, which not only reduces the impact of the diverter on the air volume output to the indoor environment, but also enables the diverter to divert the area where the air volume is relatively concentrated, so that the airflow relatively concentrated on the right side of the air outlet grille can be dispersed to other areas, compensating for the air volume difference between the right side of the air outlet grille and other areas. In addition, the window air conditioner of the present application arranges the transverse rib of the air outlet grille in a horizontal direction out of position with the air outlet guide plate, so that when the air outlet guide plate rotates to a horizontal position, the air outlet guide plate and the transverse rib are not on the same horizontal plane, thereby avoiding resonance between the air outlet guide plate and the transverse rib and generating air plate vibration sound.

[0043] The specific implementation methods of the present application are further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application but are not intended to limit the scope of the present application.

[0044] 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 may 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 may be directly connected to the other element or indirectly connected to the other element. The terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, it may be internal connectivity between two elements or an interactive 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 the specific circumstances.

[0045] In the description of the present application, it should be understood that the terms "height", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. used in the present application to indicate the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are 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 cannot be understood as a limitation on the present application.

[0046] In the description of this application, it should be understood that the terms "first" and "second" are used in this application for descriptive purposes only, and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0047] In the present application, the air conditioner performs a refrigeration cycle or a heating cycle of the air conditioner 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 or heat to the indoor space through the heat absorption or heat release of the refrigerant to adjust the temperature of the indoor space.

[0048] 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.

[0049] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid 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 a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner can adjust the temperature of the indoor space.

[0050] The window air conditioner of the present application includes an indoor unit and an outdoor unit, the outdoor unit refers to a part of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0051] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in a cooling mode.

[0052] Reference below Figure 1-Figure 10 The window air conditioner of the embodiment of the present application includes a housing 1, which is formed with an indoor air inlet 2 and an indoor air outlet 3, wherein the indoor air outlet 3 is located on the indoor side and is arranged at the upper part of the housing 1. Generally speaking, the indoor air outlet 3 is arranged horizontally, that is, the indoor air outlet 3 extends in the horizontal direction, and the outlet of the indoor air outlet 3 is vertical and faces the indoor environment.

[0053] It can be understood that the indoor air inlet 2 and the indoor air outlet 3 are constructed on the shell 1. During the use of the window air conditioner, the indoor air inlet 2 is suitable for introducing indoor air flow, and the indoor air outlet 3 is suitable for exporting air flow to the indoor environment. In this way, during the use of the window air conditioner, the indoor air flow can be introduced and updated, so that the performance of the window air conditioner can be adjusted according to the indoor environment, so as to improve the user experience of the window air conditioner.

[0054] like Figure 1-10 As shown, an indoor unit is arranged in the housing 1, and the indoor unit includes a centrifugal fan 4 and an air guide component 5.

[0055] Specifically, the centrifugal fan 4 is arranged in the shell 1, and the centrifugal fan 4 is connected with the indoor air inlet 2 and the indoor air outlet 3 of the shell 1 through the air duct assembly 6 to introduce the air outside the shell 1 from the indoor air inlet 2 into the shell 1, and under the operation and driving of the centrifugal fan 4, the introduced air is output to the room through the indoor air outlet 3.

[0056] It is understandable that the air duct assembly 6 of the indoor unit generally has an arc design with a flow guiding function so that the introduced air can be output from the indoor air outlet 3 to the indoor environment more smoothly. In the environment inside the housing 1, the centrifugal fan 4 is generally located below the indoor air outlet 3. When the indoor air is output to the indoor air outlet 3 by the centrifugal fan 4, the indoor air flows from the bottom of the indoor air outlet 3 through the air duct assembly 6 to the horizontally arranged indoor air outlet 3. In this way, based on the centrifugal force generated by the centrifugal fan 4, the air output by the centrifugal fan 4 will be more concentrated on the upper part of the indoor air outlet 3, so that the air flow velocity and air flow rate of the upper part of the indoor air outlet 3 are greater than the air flow velocity and air flow rate of the lower part of the indoor air outlet 3. In this way, if the air flow output from the indoor air outlet 3 to the indoor environment directly moves to the transverse air guide plate, a flow velocity difference will be formed above the transverse air guide plate and below the air guide plate.

[0057] like Figure 2 , 3 As shown, the air guide assembly 5 of the present application is arranged outside the indoor air outlet 3 to guide the air output to the indoor environment to flow in a specified direction. Specifically, the air guide assembly 5 includes an air outlet grille 50 and an air outlet guide plate 51, wherein:

[0058] The air outlet grille 50 is disposed at the indoor air outlet 3, and has a plurality of first grille holes 52, each of the first grille holes 52 is arranged extending vertically, and the plurality of first grille holes 52 are arranged in sequence in the horizontal direction;

[0059] The air outlet guide plate 51 is rotatably connected to the air outlet grille 50 via a rotating shaft structure and is arranged outside the first grille hole 52 so that the air output through the indoor air outlet 3 first passes through the first grille hole 52 and then flows to the air outlet guide plate 51 .

[0060] The air outlet guide plate 51 of the present application is arranged transversely in the air outlet grille 50. The air outlet guide plate 51 can be a single-layer or multi-layer structure, that is, the number of the air outlet guide plate 51 can be one or more. Fig.10As shown, a plurality of air outlet guide plates 51 are arranged in parallel in the air outlet grille 50, and the plurality of air outlet guide plates 51 are rotatably connected to the air outlet grille 50 by the same rotating shaft. The air outlet grille 50 can be divided into a plurality of air guide ducts arranged in the horizontal direction by the horizontally arranged air outlet guide plates 51. In this way, when the air flow is blown out from the indoor air outlet 3, the air output to the indoor environment can be guided to flow in a specified direction by rotating the air outlet guide plates 51.

[0061] In the first grille holes 52 of the present application, a diverter 54 is provided at the upper portion of some of the first grille holes 52 , and the diverter 54 blocks the airflow flowing out of the indoor air outlet 3 and allows the airflow to flow to the area not covered by the diverter 54 .

[0062] It should be noted that, in the present embodiment, the horizontal direction is the length direction of the air outlet grille 50, that is, the left-right direction in the figure, and the vertical direction is the width direction of the air outlet grille 50, that is, the up-down direction in the figure.

[0063] It is understandable that the transverse length of the first grille hole 52 cannot be too large to prevent a person's fingers from being inserted too far into the grille, so as to meet the safety clearance requirements of the grille. The transverse length of the first grille hole 52 cannot be too small to avoid excessive reduction of the airflow outlet area and causing air volume loss. The transverse length of the first grille hole 52 can be set according to the output parameters of the air volume, so that the size of the first grille hole 52 can meet the current air volume output requirements and safety protection requirements.

[0064] By setting a diverter 54 on the upper part of part of the first grille holes 52, most of the airflow output from the indoor air outlet 3 flows to the air outlet guide plate 51 through the first grille holes 52 where the diverter 54 is not set, and the remaining part blows to the area where the diverter 54 is located and is blocked by the diverter 54. In this way, this part of the airflow will flow to the side of the diverter 54 and supplement the area of ​​the first grille holes 52 where the diverter 54 is not set, thereby reducing the airflow rate in the area where the diverter 54 is located, that is, the upper area of ​​the first grille holes 52, while increasing the airflow rate in the area where the diverter 54 is not set, that is, the lower area of ​​the first grille holes 52. Because the air flow velocity and air flow rate at the upper part of the indoor air outlet 3 are greater than the air flow velocity and air flow rate at the lower part of the indoor air outlet 3 under the centrifugal force of the centrifugal fan 4, when the air flow rate in the upper area of ​​the first grille hole 52 decreases and the air flow rate in the lower area of ​​the first grille hole 52 increases, the air flow output through the air outlet grille 50 will be more uniform as a whole, so that there will be no large velocity difference between the air flow flowing above the air outlet guide plate 51 and the air flow flowing below the air outlet guide plate 51, thereby avoiding the air flow from moving up and down on the air outlet guide plate 51, causing the surging sound and wind plate vibration sound caused by the vibration of the air outlet guide plate 51.

[0065] It can be understood that the diverter 54, as a structural component that blocks the flow of air, is generally arranged in part of the first grille holes 52. By adjusting the ventilation area of ​​part of the first grille holes 52, the airflow distribution position is adjusted so that the airflow output through the air outlet grille 50 will be more uniform as a whole.

[0066] In some embodiments of the present application, Figure 4 , 6 As shown in FIGS. 8 and 8 , the diverter 54 is disposed at the upper portion of the first grille hole 52 and connected to the top of the first grille hole 52 , so that the airflow flowing out of the indoor air outlet 3 is diverted to the lower region of the first grille hole 52 .

[0067] Because the airflow velocity and airflow rate at the upper part of the indoor air outlet 3 are greater than the airflow velocity and airflow rate at the lower part of the indoor air outlet 3 under the centrifugal force of the centrifugal fan 4, the flow divider 54 is connected to the top of the first grille hole 52, so that the airflow concentrated in the upper area of ​​the indoor air outlet 3 can flow along the outer wall of the flow divider 54 to the lower area of ​​the first grille hole 52, so that the airflow output through the air outlet grille 50 will be more uniform as a whole. Moreover, the flow divider 54 is connected to the top of the first grille hole 52, which can avoid the gap formed by the flow divider 54 and the top of the first grille hole 52, and the airflow running through the gap to generate noise.

[0068] In some embodiments of the present application, Figure 8 , 9 As shown, the vertical length of the first grille hole 52 is H, and the vertical length of the diverter 54 is H d , and H d Within the range of 0.3H to 0.5H, it may be 0.3H, 0.35H, 0.4H, 0.45H, 0.5H, etc.

[0069] It is understandable that the diverter 54 is a structural member that blocks the flow of air. If its size is too large, it will cause a great loss to the air volume output to the indoor environment. If the size of the diverter 54 is too small, the wheezing sound cannot be improved. Since most of the airflow at the indoor air outlet 3 is concentrated in the upper part of the indoor air outlet 3, a laminar flow with a certain thickness will be formed in the upper part of the indoor air outlet 3. Generally speaking, the thickness of the laminar flow is close to 0.3H~0.5H, and the vertical length H of the diverter 54 corresponds to the thickness of the laminar flow, which can make the lower edge of the diverter 54 close to the lower limit of the laminar flow, which is conducive to the laminar flow to the lower part of the first grille hole 52 and supplement the airflow at the lower part of the indoor air outlet 3.

[0070] In some embodiments of the present application, Figure 4 , 6As shown in FIGS. 8 and 9 , there are five flow dividers 54, which are arranged in succession in the five first grille holes 52 in the transverse direction, and each flow divider 54 is arranged in one-to-one correspondence with the first grille hole 52. Specifically, along the direction in which the air flow is output to the indoor through the indoor air outlet 3, the flow divider 54 is arranged on the right side of the air outlet grille 50 and close to the edge of the air outlet grille 50; and the flow divider 54 is left empty in the first grille hole 52 on the far right, so that the first grille hole 52 on the far right remains connected.

[0071] It can be understood that, under the action of the centrifugal fan 4, the airflow output through the indoor air outlet 3 is relatively concentrated on the right side of the airflow travel direction. Therefore, a plurality of diverter components 54 are continuously arranged on the right side of the air outlet grille 50 and close to the edge of the air outlet grille 50. The air concentrated on the right side of the airflow travel direction can be distributed to other areas of the air outlet grille 50, so that the airflow output through the air outlet grille 50 is more uniform as a whole.

[0072] It should be noted that the number of diverters 54 and the area where the diverters 54 are arranged are related to the output air volume of the indoor air outlet 3. Under different output air volumes, the number of diverters 54 to be set and the area where the diverters 54 are arranged may be different. In the embodiment of the present application, five diverters 54 are arranged in succession in the horizontal direction at the five first grille holes 52, and the output air volume of the indoor air outlet 3 is 800m / h or more.

[0073] In some embodiments of the present application, Figure 4-8 As shown, the air outlet grille 50 comprises: a grille frame 50a, a horizontal rib portion 50b, a first vertical rib portion 50c and a second vertical rib portion 50d, wherein the grille frame 50a is connected to the housing 1 and arranged outside the indoor air outlet 3. The grille frame 50a forms an installation space 55, and three rotating shaft bases 56 are arranged in the installation space 55 for the air outlet guide plate 51 to be connected so that the air outlet guide plate 51 can rotate in the installation space 55.

[0074] like Fig.10 As shown, the grille frame 50a is provided with an opening 50e, the position of the opening 50e corresponds to the position of the indoor air outlet 3, and the opening 50e is located between the air outlet guide plate 51 and the indoor air outlet 3. The horizontal ribs 50b and the first vertical ribs 50c, and the horizontal ribs 50b and the second vertical ribs 50d are arranged in an interlaced manner in the opening 50e to form a protective structure of the air outlet grille 50, and provide support for the air outlet grille 50 to ensure the structural stability of the air outlet grille 50.

[0075] like Figure 4-8As shown, in some embodiments, the number of transverse ribs 50b is two, each transverse rib 50b is extended in the transverse direction and arranged in the opening 50e, and the two transverse ribs 50b are arranged vertically, thereby dividing the opening 50e into three grille ducts arranged in the transverse direction, and realizing the transverse stability of the grille frame 50a.

[0076] It should be noted that when the air outlet guide plate 51 rotates to a horizontal position, and the transverse ribs 50b are at the same level as the air outlet guide plate 51 in the horizontal position, the air outlet guide plate 51 is likely to resonate with the transverse ribs 50b, generating a vibration sound of the wind plate. Therefore, each transverse rib 50b can be configured to be arranged in a horizontal direction out of position with the air outlet guide plate 51, so that when the air outlet guide plate 51 rotates to a horizontal position, the air outlet guide plate 51 and the transverse ribs 50b are not on the same horizontal plane, thereby avoiding the air outlet guide plate 51 and the transverse ribs 50b from resonating and generating a vibration sound of the wind plate. In addition, the number of transverse ribs 50b can also be arranged according to the structure of the air outlet guide plate 51. By controlling the number of transverse ribs 50b, the transverse ribs 50b arranged in the aforementioned opening can be spaced a sufficient distance apart, ensuring that the transverse ribs 50b and the air outlet guide plate 51 can be arranged in a horizontal direction out of position.

[0077] like Figure 4-8 As shown, in some embodiments, the number of first vertical ribs 50c is thirty-three, each first vertical rib 50c is arranged between two adjacent transverse ribs 50b along the vertical extension, and the first vertical rib 50c will not exceed the position of the transverse rib 50b, and the thirty-three first vertical ribs 50c are arranged in a horizontal arrangement, dividing the grille air duct between two adjacent transverse ribs 50b into thirty-two first grille holes 52, thereby forming first grille holes 52 arranged in a vertical extension. Compared with the grille holes arranged in the horizontal direction, the first grille holes 52 can reduce the number of transverse ribs 50b, so that the air outlet grille 50 of the present application can arrange as few transverse ribs 50b as possible within the rotation range of the air outlet guide plate 51, avoiding resonance between the transverse ribs 50b and the air outlet guide plate 51.

[0078] like Figure 4-8 As shown, in some embodiments, the number of second vertical ribs 50d is eighteen, each second vertical rib 50d is arranged in the opening 50e along the vertical extension, and each second vertical rib 50d is between the transverse rib 50b and the grid frame 50a, thereby forming a connection with the grid frame 50a in the aforementioned opening 50e, thereby achieving vertical stability of the grid frame 50a.

[0079] The eighteen second vertical ribs 50d are arranged in a transverse direction, dividing the grille air duct between the transverse rib 50b and the grille frame 50a into eight second grille holes 53, so that each second grille hole 53 extends in a transverse direction and the eight second grille holes 53 are arranged in a transverse direction; and the second grille holes 53 are arranged on both sides of the first grille holes 52 in the length direction, so that the second grille holes 53 and the first grille holes 52 do not interfere with each other.

[0080] Based on the interlaced rib net formed by the transverse ribs 50b, the first vertical ribs 50c, and the second vertical ribs 50d, the air outlet grille 50 of the present application can have a relatively stable connection structure. When facing the air outlet guide plate 51 of a single-layer or multi-layer structure, by adjusting the relative positions of the transverse ribs 50b, the first vertical ribs 50c, and the second vertical ribs 50d, the positions and sizes of the first grille holes 52 and the second grille holes 53 are adjusted, so that the air outlet grille 50 can meet the protection requirements while the transverse ribs 50b will not resonate with the air outlet guide plate 51.

[0081] In some embodiments of the present application, Figure 4-8 As shown, the first vertical rib 50c and the second vertical rib 50d are arc-segment structures extending vertically, and both the first vertical rib 50c and the second vertical rib 50d protrude toward the indoor air outlet 3, and the diverter 54 is an arc-segment structure extending vertically, and the diverter 54 protrudes toward the indoor air outlet 3, so that the diverter 54 is flush with the first vertical rib 50c.

[0082] It can be understood that the arc segment structure of the first vertical rib 50c is an inferior arc shape, and the center side of the arc segment structure faces the side where the air outlet guide plate 51 is located. The first vertical rib 50c and the second vertical rib 50d both protrude toward the indoor air outlet 3, so that the first vertical rib 50c and the second vertical rib 50d can be away from the air outlet guide plate 51. During the operation of the window air conditioner, the air outlet guide plate 51 rotates in the grille frame 50a, which will cause the distance between the end of the air outlet guide plate 51 facing the indoor air outlet 3 and the first vertical rib 50c and the second vertical rib 50d to change accordingly. At different horizontal heights, the distance between the end of the air outlet guide plate 51 facing the indoor air outlet 3 and the first vertical rib 50c and the second vertical rib 50d is different, so as to avoid the air outlet guide plate 51 being too close to the first vertical rib 50c and the second vertical rib 50d, thereby preventing the air turbulence and abnormal sound from being generated.

[0083] Based on the arc segment design of the first vertical rib 50c and the second vertical rib 50d, it can be understood that the diverter 54 arranged in the first grille hole 52 is arranged corresponding to the first vertical rib 50c, and the thickness of the diverter 54 can be equal to the thickness of the first vertical rib 50c, so that the diverter 54 and the first vertical rib 50c maintain the same arc design, and the contact surface between the diverter 54 and the airflow and the contact surface between the first vertical rib 50c and the airflow can be flush, avoiding the diverter 54 and the first vertical rib 50c from forming an uneven contact surface, resulting in turbulence in the airflow output through the indoor air outlet 3, causing airflow crossflow.

[0084] Here, the indoor air outlet process of the window air conditioner preferably implemented in this application is described:

[0085] The centrifugal fan 4 introduces indoor air from the indoor air inlet 2 into the interior of the housing 1, and is driven by the operation of the centrifugal fan 4 to discharge the indoor air vertically upward out of the centrifugal fan 4. Subsequently, under the guidance of the air duct assembly 6 inside the housing 1, the introduced air flows to the indoor air outlet 3 above the centrifugal fan 4. At this time, under the influence of the centrifugal force of the centrifugal fan 4, the introduced air will adhere to the inner wall of the air duct assembly 6, and most of the air will be concentrated on the upper right side of the indoor air outlet 3 and output to the air outlet grille 50.

[0086] Based on the diverter 54 provided on the air outlet grille 50, the air output at the upper right side of the indoor air outlet 3 is blocked and cannot pass through the air outlet grille 50, and then this part of the air flows to the side of the diverter 54 and enters the areas located on the left, right and bottom of the diverter 54, thereby increasing the air flow rate in the corresponding area, while the air output at other positions of the indoor air outlet 3 directly passes through the air outlet grille 50 through the first grille hole 52, thereby making the airflow output through the air outlet grille 50 more uniform as a whole, and no large flow velocity difference is formed between the airflow flowing above the air outlet guide plate 51 and the airflow flowing below the air outlet guide plate 51, thereby avoiding the airflow from moving up and down on the air outlet guide plate 51, causing the surging sound and wind plate vibration sound caused by the vibration of the air outlet guide plate 51.

[0087] In summary, the window air conditioner provided in the embodiment of the present application introduces the air outside the shell 1 from the indoor air inlet 2 into the inside of the shell 1 through the centrifugal fan 4, and outputs it to the room through the indoor air outlet 3, so that the air output through the indoor air outlet 3 is partially concentrated on the upper part of the indoor air outlet 3 under the action of centrifugal force and blown to the air guide component 5, and the air guide component 5 corresponds to the position where the airflow is concentrated by arranging a diverter 54 in part of the first grille holes 52, and the diverter 54 is used to block the airflow flowing out of the indoor air outlet 3 and gathered at the upper part of the indoor air outlet 3, so that the airflow flows to the area not covered by the diverter 54, thereby The airflow blowing toward the area where the diverter 54 is located is dispersed, so that the airflow blowing toward the area where the diverter 54 is located can flow along the diverter 54 to the lower area corresponding to the first grille hole 52, thereby reducing the airflow rate in the area where the diverter 54 is located, that is, the upper area of ​​the first grille hole 52, while the airflow rate in the area where the diverter 54 is not set, that is, the lower area of ​​the first grille hole 52, is increased, so that the airflow output through the air outlet grille 50 is more uniform as a whole, and the airflow flowing out through the indoor air outlet 3 will not form a large flow velocity difference on the upper and lower sides of the air outlet guide plate 51, thereby avoiding the surging sound and wind plate vibration sound caused by the vibration of the air outlet guide plate 51 caused by the up and down movement of the airflow. Furthermore, the window air conditioner of the present application arranges the position of the diverter 54 based on the flow path of the airflow, so that the diverter 54 is arranged on the right side of the air outlet grille 50 and close to the edge of the air outlet grille 50, which not only reduces the impact of the diverter 54 on the air volume output to the indoor environment, but also enables the diverter 54 to divert the area where the air volume is relatively concentrated, so that the airflow relatively concentrated on the right side of the air outlet grille 50 can be dispersed and flowed to other areas, compensating for the air volume difference between the right side of the air outlet grille 50 and other areas. In addition, the window air conditioner of the present application arranges the transverse rib 50b of the air outlet grille 50 out of position with the air outlet guide plate 51 in the horizontal direction, so that when the air outlet guide plate 51 rotates to the horizontal position, the air outlet guide plate 51 and the transverse rib 50b are not on the same horizontal plane, thereby avoiding the resonance of the air outlet guide plate 51 and the transverse rib 50b and generating the wind plate vibration sound.

[0088] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present application. These improvements and substitutions should also be regarded as the scope of protection of the present application.
