[0041] 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.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0044] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0045] Reference Figure 1As shown, the air duct assembly 100 of the embodiment of the present invention can be applied to split-type air conditioning equipment 1000 such as wall-mounted air conditioners, cabinet air conditioners, and floor-standing air conditioners, and can also be applied to integrated air conditioning equipment 1000 such as mobile air conditioners and dehumidifiers. The air conditioning equipment 1000 is a device for adjusting parameters such as temperature and humidity of an indoor environment. The air conditioning equipment 1000 includes components such as a chassis 200, a housing 300, a heat exchanger 400, a wind wheel 500, and an air duct assembly 100. The air duct assembly 100 can be a component independent of the chassis 200 and the housing 300, for example, including a first housing 110 and a second housing 120; the air duct assembly 100 can also be formed by combining with partial structures of the chassis 200 and the housing 300. The wind wheel 500 is connected to the driving motor and rotates and forms negative pressure when driven by the driving motor. The wind wheel 500 drives the airflow of the indoor environment into the air conditioning equipment 1000. The airflow passes through the cooling or heating action of the heat exchanger 400 and is then blown out to the indoor environment through the air duct assembly 100 to achieve air conditioning of the indoor environment.

[0046] In order to more clearly express the solution of the embodiment of the present invention, this embodiment is described by taking a wall-mounted air conditioner indoor unit as an example. Figure 1 and Figure 2 As shown, the wall-mounted air-conditioning indoor unit of the embodiment of the present invention includes an air duct assembly 100, and the air duct assembly 100 is provided with an air duct 130 formed by a first shell 110 and a second shell 120. The first shell 110 is a volute 140 provided on the chassis 200 located on the rear side, and the second shell 120 is a volute tongue 150 provided on the casing 300 located on the front side. The first shell 110 and the second shell 120 are arranged at intervals, and the windward surface of the first shell 110 and the windward surface of the second shell 120 form the inner wall of the air duct 130. The wind wheel 500 is installed in the air duct 130 or at the inlet of the air duct 130. Since the wind wheel 500 of the wall-mounted air-conditioning indoor unit generally adopts a cross-flow wind wheel, the cross-flow wind wheel is arranged along Figure 1 The air duct 130 extends in the left-right direction as shown, and the air outlet characteristic of the crossflow impeller is that the air volume is large in the middle and small on both sides, which will cause the air outlet of the air duct 130 to have uneven air outlet.

[0047] In order to solve the problem of uneven air flow from the air outlet, refer to Figure 2 and Figure 3As shown, the air duct assembly 100 of the embodiment of the present invention is additionally provided with a protruding structure 160. The protruding structure 160 is disposed in the air duct 130, for example, on the windward surface of the first housing 110 (i.e., the side of the volute 140 facing the air duct 130), or on the windward surface of the second housing 120 (i.e., the side of the volute tongue 150 facing the air duct 130), or on both the windward surface of the first housing 110 and the windward surface of the second housing 120. It can be understood that the extension direction of the protruding structure 160 is the same as the extension direction of the crossflow impeller, that is, along the windward surface of the first housing 110. Figure 1 The raised structure 160 is configured so that the height of the air outlet cross section of the air duct 130 at the raised structure 160 tends to increase from the middle to the left and right sides, so that in the cross section in the vertical direction passing through the raised structure 160, the height of the air outlet cross section in the middle is less than the height on the left and right sides. It should be noted that the middle of the air duct 130 referred to in the embodiment of the present invention is the central position of the air duct 130 along the left and right direction, including but not limited to the exact center position, and may also include a position offset to the left and / or right of the exact center.

[0048] Reference Figure 2 As shown, the protruding structure 160 is installed downstream of the wind wheel 500 along the airflow direction, that is, the airflow first passes through the wind wheel 500 and then passes through the protruding structure 160. The protruding structure 160 can be installed at the outlet of the air duct 130, or installed at the air outlet close to the air duct 130, which is not specifically limited here. Therefore, when the airflow after heat exchange is blown out to the outlet of the air duct 130 under the action of the cross-flow wind wheel, the air outlet in the middle of the air duct 130 becomes smaller, while the air outlets on the left and right sides of the air duct 130 tend to become larger relative to the air outlets in the middle part, so that the airflow blown out by the cross-flow wind wheel is squeezed from the middle to the left and right sides and dispersed, avoiding the airflow from gathering and blowing out from the middle of the air duct 130, making the air outlet along the left and right directions more uniform, and being able to achieve a wider air outlet effect in the left and right directions, thereby improving the user experience.

[0049] It can be understood that the trend of the air outlets on the left and right sides of the air duct 130 becoming larger than the air outlets in the middle part should be understood as the air outlets in the middle part of the air duct 130 are the smallest, and the air outlets on the left and right sides of the air duct 130 are the largest. The air outlets can gradually increase from the middle of the air duct 130 to the left and right sides of the air duct 130; the air outlets can also be variable, that is, similar to a wave shape, but multiple wave peaks must meet the requirement of gradually increasing from the middle of the air duct 130 to the left and right sides of the air duct 130.

[0050] In order to achieve the above-mentioned effects, the windward cross-section (i.e., the cross-section perpendicular to the airflow direction) of the raised structure 160 of an embodiment of the present invention tends to decrease from the middle to the left and right sides, that is, the middle is high and the left and right sides are low. The windward cross-section of the raised structure 160 can be a triangular, arc-shaped, sawtooth-shaped or other structure, which is not specifically limited here, as long as the effect of guiding the airflow from the middle to the left and right sides can be achieved. It should be noted that the middle of the raised structure 160 referred to in the embodiment of the present invention is the center position of the raised structure 160 along the left and right direction, including but not limited to the exact center position, and may also include a position offset to the left and / or right of the exact center.

[0051] Reference Figure 2 and Figure 3 As shown, it can be understood that the protruding structure 160 is arranged on the side of the volute 140 facing the air duct 130. Therefore, when the height of the protruding structure 160 protruding from the first shell 110 tends to decrease from the middle to the left and right sides, the air outlet cross-section of the air duct 130 at the protruding structure 160 is constructed to be small in the middle and large on the left and right sides. Therefore, after the outlet airflow passes through the protruding structure 160, the outlet airflow is squeezed from the middle of the protruding structure 160 to the left and right sides, so that the outlet airflow with large air volume in the middle and small air volume on the left and right sides upstream of the protruding structure 160 becomes basically equal to the air volume in the middle and the air volume on the left and right sides after passing through the protruding structure 160, effectively avoiding the airflow blown out of the air outlet from gathering and blowing out from the middle, so that the air outlet is more uniform in the left and right directions. At the same time, since the air volume on the left and right sides of the air outlet is increased, the outlet airflow can be diffused outward on the left and right sides of the air outlet, and the air outlet achieves a wider air outlet effect in the left and right directions, which improves the user experience. The raised structure 160 may be in a shape that gradually decreases from the middle to the left and right sides; the raised structure 160 may also be in a variable shape, that is, similar to a wave shape, but multiple wave peaks must satisfy the shape of gradually decreasing from the middle to the left and right sides.

[0052] Reference Figure 3As shown, it can be understood that the maximum height of the raised structure 160 is set at the middle position of the air duct 130 along the left-right direction, and the height of the raised structure 160 gradually decreases to zero on both sides of the air duct 130 along the left-right direction. The minimum spacing between the first shell 110 and the second shell 120 in the air duct 130 is H, that is, the minimum spacing between the volute 140 and the volute tongue 150 is H, and the maximum height of the raised structure 160 is H1, which satisfies: 0.1≤H1 / H≤0.75. When the above range is met, the airflow in the middle of the air duct 130 can be diverted and dispersed to the left and right sides of the air duct 130, so that the air volume in the left-right direction of the air outlet is more even and the air outlet is more uniform. When it is less than the above parameter range, due to the high height of the raised structure 160, the wind resistance and wind noise of the airflow are large when the airflow passes through the middle of the air duct 130, resulting in large air volume loss and small air volume in the middle of the air outlet. When it is greater than the above parameter range, due to the low height of the raised structure 160, the air flow guidance effect is not obvious when passing through the middle of the air duct 130, and the air volume guided to the left and right sides is small, resulting in the air volume on the left and right sides of the air outlet not being significantly increased, and uniform air outlet cannot be achieved.

[0053] Reference Figure 1 and Figure 3 As shown, it can be understood that the height of the protruding structure 160 protruding from the volute 140 gradually decreases from the middle of the protruding structure 160 to the left and right sides, which is conducive to guiding the outlet airflow from the middle of the air duct 130 to the left and right sides of the air duct 130, reducing the resistance during the diversion, improving the smoothness of the diversion, and making the outlet airflow dispersed more evenly from the middle to the left and right sides. For example, the wall surface (i.e., the upper end surface) of the protruding structure 160 facing one end of the second shell 120 can be constructed as a plane inclined from the middle to the left and right sides, i.e., a triangle; or it can be constructed as an arc surface that is high in the middle and low on the left and right sides; it can also be constructed as a stepped surface that gradually becomes shorter from the middle to the left and right sides, etc.

[0054] Reference Figure 3 As shown, it can be understood that the wall surface of the protruding structure 160 at one end facing the second housing 120 is an arc surface. The arc surface design is adopted, so that the change amount of the height of the air outlet in the middle of the air duct 130 to the height of the air outlet on the left and right sides of the air duct 130 gradually increases, that is, from the middle to the left or right direction, the change of the air outlet height gradually increases at each same interval, which is conducive to the control of the air volume in the middle of the air duct 130, so that the airflow in the middle of the air duct 130 is more directed to the left and right sides of the air duct 130, so that the air volume of the entire air duct 130 along the left and right directions reaches a closer effect.

[0055] Reference Figure 2 As shown, the protruding structure 160 may be a sheet-like structure, for example, formed by cutting or injection molding a plastic plate, which is easy to install and has low processing difficulty.

[0056] It can be understood that the protruding structure 160 is a convex strip 164 extending in the left-right direction. The convex strip 164 is constructed as a separate structure. The convex strip 164 can be fixedly connected to the inner wall of the air duct 130 by bonding, screwing, riveting, etc. The connection between the convex strip 164 and the inner wall of the air duct 130 is sealed and has no gap, so that it is fixedly connected to the first shell 110. In addition, the convex strip 164 can also be fixedly connected or integrally formed with other structures of the air duct assembly 100, so that when the other structures of the air duct assembly 100 and the first shell 110 are assembled, the convex strip 164 can protrude on the inner wall of the air duct 130. Figure 2 In the illustrated embodiment, the convex strip 164 is fixedly connected between the shell of the lower air duct 130 and the volute 140 of the air duct assembly 100. For example, the convex strip 164 is fixedly connected to the shell of the lower air duct 130 or to the volute 140, which makes installation more convenient.

[0057] Reference Figure 5 As shown, the protrusion structure 160 of another embodiment of the present invention can also be configured as a block structure extending along the airflow direction of the air duct 130. However, in order to reduce the influence of the block-shaped protrusion structure 160 on the wind resistance, the thickness of the protrusion structure 160 on the inner wall of the air duct 130 gradually increases along the airflow direction, thereby forming a first inclined surface 161 that is conducive to wind guidance.

[0058] Reference Figure 4 and Figure 5 As shown, it is understandable that the protrusion structure 160 can also be integrally formed with the first housing 110. For example, the protrusion structure 160 and the volute 140 are integrally injection molded to improve the overall strength of the protrusion structure 160. In the embodiment of the present invention, the protrusion structure 160 can be a sheet structure or a block structure.

[0059] Reference Figure 6 , Figure 7 and Figure 8As shown, in another embodiment of the air duct assembly 100 of the present invention, the protruding structure 160 is arranged on the windward surface of the volute tongue 150. When the height of the protruding structure 160 protruding from the volute tongue 150 tends to decrease from the middle to the left and right sides, the air outlet cross section of the air duct 130 at the protruding structure 160 is constructed to be small in the middle and large on the left and right sides. Therefore, after the outlet air flow passes through the protruding structure 160, the outlet air flow is squeezed from the middle of the protruding structure 160 to the left and right sides to disperse, so that the outlet air flow with large air volume in the middle and small air volume on the left and right sides upstream of the protruding structure 160 becomes substantially equal to the air volume in the middle and the air volume on the left and right sides after passing through the protruding structure 160, effectively avoiding the air flow blown out of the air outlet from gathering and blowing out from the middle, so that the air outlet in the left and right directions is more uniform. At the same time, since the air volume on the left and right sides of the air outlet is increased, the outlet air flow can be diffused outward on the left and right sides of the air outlet, and the air outlet achieves a wider air outlet effect in the left and right directions, thereby improving the user experience. The raised structure 160 may be in a shape that gradually decreases from the middle to the left and right sides; the raised structure 160 may also be in a variable shape, that is, similar to a wave shape, but multiple wave peaks must satisfy the shape of gradually decreasing from the middle to the left and right sides.

[0060] It can be understood that the volute tongue 150 includes a first section 151 close to the wind wheel 500, a second section 152 close to the air outlet, and a bent section 153 connecting the first section 151 and the second section 152. The protruding structure 160 can be fixedly connected to the first section 151 of the volute tongue 150, or fixedly connected to the second section 152 of the volute tongue 150, or fixedly connected to the bent section 153 of the volute tongue 150.

[0061] Reference Fig. 9 and Fig.10 As shown, the protrusion structure 160 of another embodiment of the present invention includes a plurality of bosses 162 arranged in the left and right directions. The plurality of bosses 162 are configured such that the maximum height of the boss 162 located in the middle of the protrusion structure 160 protruding from the volute tongue 150 is greater than the maximum height of the boss 162 located on the left or right side of the boss 162 protruding from the volute tongue 150. It can be understood that the maximum height of the boss 162 located in the middle is the highest, and the maximum heights of the bosses 162 on the left and right sides of the boss 162 located in the middle are lower than the boss 162 in the middle, and the maximum heights of the plurality of bosses 162 of the protrusion structure 160 tend to decrease from the middle to the left and right sides. The boss 162 located in the middle can be one boss 162, or two or more. Therefore, under the guiding effect of the plurality of bosses 162, the outlet airflow is squeezed and dispersed layer by layer to the left and right sides, so as to avoid the airflow from gathering and blowing out from the middle of the air duct 130, so that the air outlet in the left and right directions is more uniform. At the same time, since the air volume on the left and right sides of the air outlet is increased, the outlet airflow can diffuse outward on the left and right sides of the air outlet, achieving a wider air outlet effect in the left and right directions, thereby improving the user experience.

[0062] Reference Fig.10 As shown, it can be understood that the end of the boss 162 facing the first shell 110 is provided with a second inclined surface 163, and the second inclined surface 163 is inclined from the direction away from the middle of the protruding structure 160 toward the second shell 120. The design of the second inclined surface 163 is more conducive to guiding the airflow to the left and right sides, reducing the wind resistance and wind noise during the guiding process.

[0063] Reference Fig.10 As shown, it can be understood that the height of the protruding structure 160 protruding from the volute tongue 150 gradually decreases from the middle of the protruding structure 160 to the left and right sides. This is conducive to guiding the outlet airflow from the middle of the air duct 130 to the left and right sides of the air duct 130, reducing the resistance during the diversion, improving the smoothness of the diversion, and making the outlet airflow dispersed more evenly from the middle to the left and right sides. For example, the wall surface (i.e., the lower end surface) of the protruding structure 160 facing one end of the first shell 110 can be constructed as a plane inclined from the middle to the left and right sides, i.e., a triangle; or it can be constructed as an arc surface that is high in the middle and low on the left and right sides, etc.

[0064] Reference Figure 8 As shown, it can be understood that the wall surface of the protruding structure 160 facing one end of the first housing 110 is an arc surface. The arc surface design is adopted, so that the change amount of the height of the air outlet in the middle of the air duct 130 to the height of the air outlet on the left and right sides of the air duct 130 gradually increases, that is, from the middle to the left or right direction, the change of the air outlet height gradually increases at each same interval, which is conducive to the control of the air volume in the middle of the air duct 130, so that the airflow in the middle of the air duct 130 is more directed to the left and right sides of the air duct 130, so that the air volume of the entire air duct 130 along the left and right directions reaches a closer effect.

[0065] Reference Figure 7 As shown, it can be understood that the protruding structure 160 is integrally formed on the volute tongue 150, for example, integrally injection molded with the volute tongue 150, so that the volute tongue 150 and the protruding structure 160 are integrally configured to form a volute tongue structure whose height gradually decreases from the middle to the left and right sides, thereby improving the overall strength of the protruding structure 160. As another embodiment, the protruding structure 160 is a convex strip 164 extending in the left-right direction, and the convex strip 164 is configured as a separate structure. The convex strip 164 can be fixedly connected to the inner wall of the air duct 130 by bonding, screwing, riveting, etc., so as to be fixedly connected to the volute tongue 150.

[0066] It is understandable that the protruding structure 160 may be a sheet-like structure, for example, formed by cutting or injection molding a plastic plate, which is easy to install and has low processing difficulty. The protruding structure 160 may also be a block-like structure, formed by extending along the airflow direction of the air duct 130. In order to reduce the influence of the block-like protruding structure 160 on the wind resistance, the thickness of the protruding structure 160 on the inner wall of the air duct 130 gradually increases along the airflow direction, thereby forming a third inclined surface that is conducive to guiding the wind.

[0067] It can be understood that the protrusion structure 160 of another embodiment of the present invention can achieve control of the air outlet of the air duct 130 by cooperating between a first protrusion provided on the first shell 110 and a second protrusion provided on the second shell 120. Please refer to the principles of the above embodiments for specific understanding. In order to avoid repetition, it will not be repeated here.

[0068] Reference Figure 1 and Figure 2 As shown, an air conditioning device 1000 according to an embodiment of the present invention includes the above air duct assembly 100, which is installed in the air conditioning device 1000 and can supply air to the indoor environment.

[0069] It can be understood that the air conditioning equipment 1000 of the embodiment of the present invention adopts the air duct assembly 100 of the first aspect embodiment. The air duct assembly 100 is formed by setting a protruding structure 160 on the windward side of the air duct 130 formed by the first shell 110 and the second shell 120. The protruding structure 160 extends in the left-right direction and is configured to make the height of the air outlet cross-section of the air duct 130 increase from the middle to the left and right sides, so that the air outlet in the middle of the air duct 130 becomes smaller, while the air outlet on the left and right sides of the air duct 130 tends to increase relative to the air outlet in the middle part, so that the airflow of the air duct 130 is dispersed from the middle to the left and right sides, reducing the situation where the airflow is gathered and blown out from the middle of the air duct 130, thereby achieving the effect of uniform air outlet of the air duct assembly 100 in the left and right directions, realizing uniform air supply of the air conditioning equipment 1000, and improving user experience.

[0070] Since the air conditioning device 1000 adopts all the technical solutions of the air duct assembly 100 of the above embodiment, it has at least all the beneficial effects brought by the technical solutions of the above embodiment, which will not be repeated here.

[0071] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
