In the prior art, an air outlet assembly of a bladeless air conditioner includes an inner casing and an outer casing. A second air duct flow passage is defined between the inner shell and the outer shell, and the inner shell is of a cylindrical structure with a first air duct. The air after the regulation can be passed through in this second wind channel, then discharge the air into first wind channel inner chamber, and then discharge, reach the purpose of adjusting air within a certain range. However, the air outlet with the existing structure has the technical problem of unstable structure.

In order to solve the technical problem, the inventor provides an air outlet assembly through a series of research works, and the air outlet assembly is mainly applied to air conditioning equipment and is particularly suitable for the working condition of large air volume. Compare in air conditioning equipment's among the prior art amount of wind, because the stability of the air outlet subassembly that this embodiment provided improves, the amount of wind of the air conditioning equipment who has used this air outlet subassembly can generally improve 2.5 to 3 times, can improve the quality of air in the certain region sooner, for example high-efficient cooling, remove impurity etc.. The exchange of cold and hot air in the room is completed in the first air channel of the air outlet, the temperature of the blown air is comfortable, the room temperature is effectively adjusted, the body feeling is better, the air conditioner with the safe air outlet and easy management can effectively solve the problems of safe use and sense of customers, the body feeling of the customers is better, and the problem of easily getting air conditioner diseases is solved.

Specifically, referring to fig. 1, an embodiment of the present invention provides an air conditioning apparatus, including an air outlet assembly 1. The outlet assembly 1 includes an inner housing 100, an outer housing 110 and a support 120.

The inner case 100 configures a first duct 100a and an air outlet 100d communicating with the first duct 100 a. The airflow entering the first air duct 100a is discharged out of the air outlet assembly 1 through the air outlet 100d, so as to adjust the external air.

The outer casing 110 surrounds the outer side of the inner casing 100, and an annular passage formed by the interval between the two is a second air duct 110 a. The second air duct 110a is communicated with the first air duct 100a, and the airflow in the second air duct 110a flows into the first air duct 100 a.

In the prior art, when the air volume in the second air duct 110a is increased, an acting force is generated on the outer shell 110 or the inner shell 100 in the flow, and the acting force causes a tendency of relative movement between the outer shell 110 and the inner shell 100, so that the stability of the shell assembly structure can limit the increase of the air volume; therefore, in the technical solution of the embodiment of the present invention, the outer shell 110 and the inner shell 100 are further connected by the support member 120, the support member 120 forms the outer shell 110 and the inner shell 100 into an effective integral structure, the movement amount or deformation amount of the outer shell 110 and the inner shell 100 is effectively limited in the spacing direction of the outer shell 110 and the inner shell 100, and the stability of the structure is improved; because the supporting member 120 forms a relatively stable integral structure with the inner casing 100 and the outer casing 110, the external force generated by the significant improvement of the air volume cannot cause the inner casing 100 and the outer casing 110 to generate an excessive displacement, and thus the air outlet assembly has relatively high stability when the air volume is improved.

In addition, in the prior art, the load during transportation may also cause the outer shell 110 and the inner shell 100 to be unstable. The outer shell 110 and the inner shell 100 form a stable integral structure through the supporting member 120, the outer shell 110 does not fall off, the second air duct 110a does not change in space, and the quality of the product when being sent to a client is effectively improved.

In addition, the air outlet subassembly of prior art is in the transportation, and the shell body also probably produces certain position and removes, leads to the amount of wind and designs the amount of wind and produces huge deviation, and produces the noise easily. And the utility model discloses an overall structure that the interior outer casing of air outlet subassembly formed has reduced vibrations, and the noise can reduce 4 to 6 decibels.

In a specific implementation process, generally, the inner casing 100 is a thin-walled cylindrical structure, a space defined by an inner wall of the inner casing 100 is a first air duct 100a, and one end of the inner casing 100 is an air outlet 100d of the air outlet assembly. The air outlet assembly further has an air inlet 100e, and the air inlet 100e and the air outlet 100d are disposed at two axially opposite ends of the air outlet assembly.

In a specific implementation, the outer shell 110 is also of a thin-walled cylindrical configuration with an inner diameter greater than an outer diameter of the inner shell 100. The inner housing 100 is installed inside the cavity of the outer housing 110, and further, the inner wall of the outer housing 110 and the outer wall of the inner housing 100 form a second air duct 110 a. The end of the inner case 100 provided with the air outlet 100d is further provided with a sealing plate 100f disposed toward the outer case 110, and the sealing plate 100f is hermetically connected with the outer case 110 such that the second air duct 110a is communicated with only the first air duct 100 a.

Generally, at least a portion of the second air chute 110a is coaxial with the first air chute 100 a. For example, one end of the second air duct 110a away from the air outlet 100d is communicated with the first air duct 100a in an extending and bending manner, and at this time, a part of the second air duct 110a is coaxial with the first air duct 100 a; in this structure, the support 120 is entirely located within the second air path 110 a. For another example, the air outlet assembly further includes a wind guiding housing having a wind channel, the wind guiding housing is a curved housing, and the wind guiding housing is connected to the outer housing, such that the second wind channel 110a is communicated with the first wind channel 100a through the wind channel of the wind guiding housing, at this time, all parts of the second wind channel 110a are coaxial with the first wind channel 100a, in this structure, at least a part of the support 120 is located in the second wind channel 110a, and another part may be located in the wind channel of the wind guiding housing.

In some embodiments, the outer shell 110 and the inner shell 100 are both solids of revolution, and the support member 120 runs parallel to a direction generally parallel to the spacing of the outer shell 110 and the inner shell 100, i.e., radial. The support member 120 may be integrally connected to the outer shell 110, or may be integrally connected to the inner shell 100, or the support member 120 may be a separate component. In general, the windward side of the support 120 is a curved surface, so that the airflow in the second air duct 110a can better bypass the support 120. For example, the support 120 may be configured as a cylinder. Alternatively, the support 120 may be configured as a member having several grids to facilitate the passage of the air flow within the second air duct 110 a.

As an alternative to the above embodiment, the supporting member 120 has a plurality of supporting members 120, and the plurality of supporting members 120 are arranged at intervals along the circumferential direction of the inner shell 100. Typically, the supports 120 are evenly spaced. For example, the number of the supporters 120 may be 2, 3, or more. In the present embodiment, the number of the supporting members 120 is 4, and the angle between any two adjacent supporting members 120 is 90 °.

As an alternative implementation manner of the above embodiment, as shown in fig. 1 and fig. 2, an end of the inner housing 100 away from the air outlet 100d is bent toward the outer housing 110 to form a bent portion 100b, and the bent portion 100b is connected to the support 120. The bending portion 100b is formed by bending toward the outer casing 110, so that the length of the supporting member 120 can be reduced, and the bending amount of the supporting member 120 is reduced when the supporting member is subjected to wind force, thereby improving the stability of the support. In some embodiments, the warpage portions 100b may be circumferentially spaced, that is, the number of the warpage portions 100b is equal to the number of the supporters 120, and each warpage portion 100b is provided with a corresponding supporter 120. In other embodiments, the buckling portion 100b may be a ring-shaped structure formed by being continuously arranged along the circumferential direction, and the supporting members 120 are sequentially connected to different positions of the ring-shaped structure at intervals along the circumferential direction.

Of course, in other embodiments, the inner housing may not have a bent portion, and the support member 120 may be disposed on the outer wall of the inner housing.

As an alternative embodiment of the above embodiment, as shown in fig. 1 and fig. 2, the air outlet assembly 1 further includes an air guide casing 130. The air guide housing 130 is used for guiding the airflow of the second air duct 110a into the first air duct 100 a. One end of the air guide casing 130 is connected to the outer casing 110, and the other end of the air guide casing 130 extends toward the inner casing in a bending manner, so that a space is defined between the air guide casing 130, the outer casing 110 and the inner casing 100, and the space serves as a transition air duct between the second air duct 110a and the third air duct 130 a. The other end of the air guiding housing 130 is bent and extended toward the inner housing 100 to form a mouth 130b, and the mouth 130b and the warping portion 100b are spaced apart from each other to define a third air duct 130a communicating with the second air duct 110 a. The air guide housing 130 has an arc shape, one end of which is connected to the outer housing 110, and the other end of which extends toward the inner housing 100 to form a mouth 130 b. The mouth 130b generally extends partially into the second air duct 110 a. In this embodiment, the mouth 130b and the warping portion 100b are disposed at an interval, and when the air flow enters the third air duct 130a, the curved shape of the warping portion 100b can guide the air flow to be ejected toward the first air duct 100a, so as to guide the flow direction of the air flow and avoid the turbulence of the air flow.

In a specific embodiment, the air guide shell 130 and the outer shell 110 may be connected by sealing with a rubber ring and by screwing, so as to avoid air leakage. Alternatively, the wind guide housing 130 and the outer housing 110 may be integrally formed, that is, the wind guide housing 130 may be a part of the outer housing 110. The inner surface of the first air duct 100a of the mouth 130b and the outer surface of the warping portion 100b are spaced to form a channel, which is a third air duct, and the mouth 130b is spaced from the warping portion 100b and thus has an opening through which the air flow in the third air duct 130a is ejected into the first air duct 100 a. In general, the ejection direction of the nozzle 130b is inclined to the axial direction of the first air path 100 a.

As an alternative to the above embodiment, the cross-sectional area of the third air duct 130a gradually decreases along the flowing direction of the air flow in the third air duct 130 a. In this way, the gas is caused to flow at a continuously increasing flow rate, which facilitates the gas flow to have a sufficient velocity as it exits the nozzle 130b to generate a drag suction. Further, the third air path 130a can be formed to be curved along the curved axis of the air guide housing 130 due to the curved arrangement of the air guide housing 130, and the flow rate and the flow velocity of the air ejected from the mouth 130b can be increased by the air passing. In general, the third air duct 130a may exhibit a curved drop-like configuration.

As an optional implementation manner of the above embodiment, the air outlet assembly further includes an air inlet 100e disposed opposite to the air outlet 100d, and the air inlet 100e is communicated with the first air duct 100 a. For example, the air inlet 100e is located near an end of the inner housing 100 having the warped portion 100b, and the air outlet 100d is located at an end of the inner housing 100 away from the warped portion 100 b. When the air flow (first air flow) is ejected toward the first air duct 100a through the mouth portion 130b, a pressure difference is generated between the front and the rear of the air inlet 100e, specifically, the air pressure outside the air inlet 100e is greater than the air pressure inside the first air duct 100a, and then the air flow ejected from the mouth portion 130b sucks the air (second air flow) outside the air inlet 100e into the first air duct 100 a. In the first air duct 100a, the first air flow and the second air flow are mixed to achieve the effect of adjusting the second air flow, so that the air in a certain area can be adjusted relatively quickly. The temperature of an air outlet of a traditional air conditioner is about 15 ℃ lower than the ambient temperature, blown air is very cold and is directly blown on the body to be too cold, air conditioner diseases are easily caused, and the problem of very poor body feeling is solved. Therefore, the air conditioning equipment can reduce temperature difference and increase comfort degree by mixing the first air flow and the second air flow. For this reason, the outlet assembly 1 is often used for the regulation of the internal circulation of indoor air. Further, the larger the flow velocity of the first air flow ejected from the nozzle is, the larger the pulling suction force is generated, so that the sectional area of the third air duct 130a becomes gradually smaller along the flow direction of the air flow in the third air duct 130a, so as to increase the flow velocity. Furthermore, in order to reduce the loss of the first air flow, the mouth 130b is preferably located inside the air inlet 100e and near the air inlet 100e, so as to draw the external air.

As an optional implementation manner of the above embodiment, the warping portion 100b is provided with a reinforcing structure 100c, and the reinforcing structure 100c is connected with the support 120. Because the airflow flowing direction of the warping portion 100b changes, a certain spiral can be generated, and the weak stress link of the air outlet assembly 1 is formed at the position, and therefore, the reinforcing structure 100c is arranged on the warping portion 100 b. The reinforcing structure 100c may be a reinforcing plate connected to the bent portion 100b, a reinforcing rib connected to the bent portion 100b, or a local thickening of the bent portion 100 b. The supporting member 120 is connected to the reinforcing structure 100c, for example, the supporting member 120 can be plugged into the reinforcing structure 100 c.

As an optional implementation manner of the above embodiment, a groove 110c is provided on a side of the outer housing 110 facing the inner housing 100, and the support member 120 is embedded in the groove 110 c. The side of the outer case 110 facing the inner case 100 is an inner surface of the outer case 110 on which a groove 110c is configured to be provided corresponding to the supporter 120. The cross section of the groove 110c matches the size and shape of the support member 120, so that the support member 120 can be assembled with the outer housing 110. The number of the grooves 110c is identical to the number of the supporters 120. The grooves 110c correspond one-to-one to the supporters 120. By fitting the supporter 120 into the groove 110c, the outer case 110 is formed in an integral structure with the inner case 100 through the supporter 120.

As an alternative to the above embodiment, the cross-sectional area of the first air duct 100a gradually increases along the flowing direction of the airflow in the first air duct 100 a. In the present embodiment, the first air duct 100a extends along the direction of the air flow, i.e., has a certain length in the axial direction thereof, that is: the inner housing 100 has a substantially truncated cone-shaped hollow cone structure, so that the air flow entering from the air inlet 100e and the air flow exiting from the second air duct 110a can be mixed more uniformly in the first air duct 100 a. Moreover, the sectional area of the first air duct 100a gradually increases along the flowing direction of the airflow in the first air duct 100a, which also indicates that the aperture of the air inlet 100e is smaller than the aperture of the air outlet 100d, mainly: the air flow generated by the nozzle 130b has a large velocity, and if the diameter of the air inlet 100e is small, the air outside the air inlet 100e is easily drawn into the first air path 100a, and if the diameter of the air outlet 100d is large, the area of the air flow to be ejected is large, and the diffusion area is increased.

In the specific implementation process, the ratio of the caliber of the air outlet 100d to the caliber of the air inlet 100e is 3: 1-4: 3 is preferred; for example, the aperture of the air outlet 100d is 200-300 mm, and the aperture of the air inlet 100e is 100-150 mm. The axial length of the inner housing 100 is between 200mm and 400 mm. The above is only one parameter in a conventional situation, and in other special cases, the parameters can be adjusted appropriately by those skilled in the art.

The support 120 has first and second ends opposite in a radial direction of the outlet assembly.

In some embodiments, as shown in fig. 5, the support member 120 has a first end and a second end opposite to each other, the first end is fixedly connected to the inner housing 100, and the second end is fixedly connected to the outer housing 110. For example, the first end of the supporting member 120 is ultrasonically welded to the inner case 100, and the second end is ultrasonically welded to the outer case 110. The first end and the second end of the support member 120 each have a portion that is flat so as to be easily welded to the inner case 100 and the outer case 110 by ultrasonic welding. For example, at least a portion of the buckling portion 100b is a plane, and the plane structure of the first end of the supporter 120 and the plane structure of the buckling portion 100b are welded together by ultrasonic welding. For example, at least a portion of the extension 110d may be planar, and the second planar structure of the support member 120 may be ultrasonically welded to the planar structure of the extension 110 d.

As shown in fig. 6 and 7, in some alternative embodiments, the supporter 120 is embedded in the warping portion 100 b. Specifically, the buckling portion 100b is provided with an insertion hole, a first end of the support 120 is inserted into the buckling portion 100b, the support 120 is connected with the inner housing 100, and the buckling portion 100b provides effective support for the support 120. Further, the warping portion 100b also starts to have a screw hole penetrating through the insertion hole, and the supporter 120 has another screw hole fitting the screw hole, and the two screw holes are connected by the first fixing member 150, thereby further effectively fixing the supporter 120 to the warping portion 100 b. The first fixing member 150 may be a screw, a stud, or other threaded fastener.

As an alternative to the above embodiment, as shown in fig. 6 and 7, one side of the outer housing 110 facing the inner housing 100 has an extension 110d extending toward the inner housing 100, and the extension 110d is connected to the support 120. The extension 110d is formed to extend toward the inner case 100, so that the length of the support 120 can be reduced, and the deflection of the support 120 is reduced when the support is subjected to wind, thereby improving the stability of the support.

In addition, as shown in fig. 4, an embodiment of the present invention further provides an air conditioning apparatus, especially a mobile air conditioner without a wind blade technology. The air conditioning apparatus also supplies an air supply assembly 2. As the name implies, the air supply assembly 2 supplies air to the air outlet assembly 1, where the air may be understood as air (e.g., cooled air or heated air) after temperature adjustment, air after impurity removal, and/or air (e.g., air after humidity increase or air after humidity removal) after humidity adjustment. In some embodiments, the air supply assembly 2 includes a regulating element 220 and a power element 210. The adjusting element 220 may be at least one of a filter, an evaporator, a condenser, a humidifier, and a dehumidifier. The power element 210 mainly sucks the external air into the air supply assembly 2 from the air suction opening of the air supply assembly 2, and sends the external air into the air outlet assembly 1 after performing parameter adjustment on the external air through the adjusting element 220.

In some embodiments, the outer casing 110 is configured with an air inlet channel 110b communicated with the second air duct 110 a. The air inlet passage 110b is a radial passage. In the use state, the air outlet assembly 1 is located at the upper part of the air supply assembly 2, and thus the air inlet channel 110b is formed on the lower side wall of the outer casing 110. The outer casing 110 is connected to the air supply assembly 2, and the air supply channel of the air supply assembly 2 is hermetically communicated with the air inlet channel 110 b. The adjusted air is sent to the air inlet channel 110b through the air supply channel by the air supply assembly 2, the air flow sequentially enters the second air channel 110a, enters the third air channel 130a, is discharged into the first air channel 100a through the mouth 130b, a certain negative pressure is generated at the mouth 130b, and then the air at the first air inlet 100e is sucked into the first air channel 100a, and the mixed air flow is discharged through the second air outlet 100 d.

The indoor air temperature reduction will be described as an example, and is shown in fig. 4. The air supply assembly 2 comprises an air supply shell, and the air supply shell limits an accommodating cavity and an inner cavity flow channel. An evaporator and a fan are arranged in the accommodating cavity. The shell is provided with an air suction opening and an air supply channel. When the fan starts, the outside air enters the containing cavity through the air suction opening, flows in the cavity flow channel of the structure, and is cooled through the air of the evaporator, and then is discharged to the air outlet assembly 1 through the air supply channel.

Further, the air conditioning device may also be provided with moving wheels, for example the air conditioning device may be a mobile air conditioner. For example, universal wheels are arranged at the bottom of the air supply assembly 2, so that the air conditioning equipment can be moved in a certain area range.

Furthermore, the embodiment of the utility model provides a still provide an air outlet subassembly 1. The outlet assembly 1 includes an inner housing 100, an outer housing 110 and a support 120.

In the prior art, when the air volume in the second air duct 110a is increased, a force is generated on the outer shell 110 or the inner shell 100 in the flow, and the force causes a tendency of relative movement between the outer shell 110 and the inner shell 100, so that the stability of the shell assembly structure can limit the increase of the air volume; therefore, in the technical solution of the embodiment of the present invention, the outer shell 110 and the inner shell 100 are further connected by the supporting member 120, and the supporting member 120 forms the outer shell 110 and the inner shell 100 into an effective integral structure, so as to effectively limit the moving amount or deformation amount of the outer shell 110 and the inner shell 100 in the spacing direction of the outer shell 110 and the inner shell 100, and improve the stability of the structure; because the supporting member 120 forms a relatively stable integral structure with the inner casing 100 and the outer casing 110, the external force generated by the significant improvement of the air volume cannot cause the inner casing 100 and the outer casing 110 to generate an excessive displacement, and thus the air outlet assembly has relatively high stability when the air volume is improved.

The above is only the optional embodiment of the present invention, and not limiting the patent scope of the present invention, all under the inventive concept of the present invention, the equivalent structure transformation made by the contents of the specification and the attached drawings is utilized, or the direct/indirect application is included in other related technical fields in the patent protection scope of the present invention.
