Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to an air conditioner with an annular air outlet. Background Art

[0002] Air conditioning, also known as air conditioner, refers to a device that uses artificial means to quickly adjust and control parameters such as the ambient temperature within a building or structure.

[0003] In today's air conditioners, air flows directly out of an air outlet and blows directly towards the user, making the user feel less comfortable. Summary of the Invention

[0004] In order to solve at least one problem existing in the above-mentioned prior art, according to one aspect of the present invention, an air conditioner with an annular air outlet is provided, comprising: a body, the body comprising a main body and an air duct structure arranged in the main body, the air duct structure having an annular air duct and an annular air outlet, the annular air duct and the annular air outlet being connected to each other; an air supply system, arranged in the main body, for supplying air to the annular air duct.

[0005] In this way, by providing a duct structure in the main body and forming a ring-shaped duct in the duct structure, after air is supplied to the ring-shaped duct through the air supply system, the wind flow can be blown out from the ring-shaped air outlet, so that the wind flow blows towards the user in a ring shape, reducing the user's direct blowing feeling and improving comfort.

[0006] In some embodiments, the body further includes a front shell and a panel, the front shell and the main body encapsulate the air duct structure and the air supply system, the front shell has a front opening, the front opening is used for the airflow of the annular air outlet to flow out, and the panel is movably connected to the front shell to open or close the front opening.

[0007] In this way, an encapsulated space is formed by setting the front shell and the main body, so that the entire air conditioner has an overall aesthetic and practicality, and the opening and closing of the front opening is controlled by the panel to protect the annular air outlet and avoid contamination by dust and impurities when not in use; at the same time, by setting the front shell and the panel to block, the annular air outlet is prevented from being directly exposed to the air, and dew condenses on the surface of the duct structure due to the higher temperature air contacting the lower temperature duct structure in the cooling state.

[0008] In some embodiments, the air conditioner includes a lower air outlet structure, which is located below the annular air outlet and connected to the annular air duct, and the lower air outlet structure includes at least one lower air outlet.

[0009] In this way, the lower air supply is carried out through the lower air outlet structure, which can cooperate with the upper air outlet and the annular air outlet to supply air together, providing users with more air supply methods.

[0010] In some embodiments, the lower air outlet structure has a plurality of lower air outlets, and the plurality of lower air outlets are arranged in sequence from top to bottom.

[0011] In this way, by arranging multiple lower air outlets up and down, different lower air outlets can be selectively used according to the height of the obstacles on the support surface, such as using lower air outlets at higher positions, to achieve the effect of avoiding obstacles and allow the airflow to flow to a farther location.

[0012] In some embodiments, the downwind outlet structure includes a connecting frame and a supporting frame, wherein the connecting frame and the supporting frame respectively form at least one downwind outlet, the connecting frame is connected between the air duct structure and the supporting frame, and the connecting frame, the annular air duct and the supporting frame can be interconnected.

[0013] In this way, by setting different structural parts of the connecting frame and the supporting frame, it is possible to control whether the lower air outlets set in each part discharge air, and it is possible to control the opening position of the lower air outlets on each part.

[0014] In some embodiments, the air duct structure includes a first switch door, which is used to open or close the annular air duct so that when the annular air duct is in a closed state, the airflow delivered by the air supply system flows to the lower air outlet structure.

[0015] In this way, by providing the first switch door to close the annular air duct, the airflow provided by the lower air supply mechanism can be controlled to flow entirely to the lower air outlet structure, allowing the lower air outlet structure to retain a larger amount of airflow. Alternatively, in other usage modes, when the first switch door is in the open state, the airflow delivered by the air supply system can flow out not only from the annular air outlet but also from each lower air outlet, allowing the air conditioner to have multiple air outlet modes.

[0016] In some embodiments, the connecting frame is provided with a lower air outlet, which is a first lower air outlet. The first lower air outlet has a first outlet portion and a second outlet portion. The first outlet portion faces the supporting frame. The first outlet portion and the second outlet portion are connected to each other so that the airflow delivered from the first outlet portion can be delivered from the second outlet portion. The second outlet portion and the annular air outlet face the same side of the main body.

[0017] In this way, by setting the first lower air outlet to have a first outlet part and a second outlet part, the airflow flows downward from the first outlet part and then turns to flow out from the second outlet part, so that the air conditioner has more air outlet methods and realizes the diversified development of the air conditioner structure.

[0018] In some embodiments, the lower air outlet structure also includes a second opening and closing door, which is movably connected to the connecting frame and is used to open or close the first outlet portion so that when the first outlet portion is in a closed state, the airflow delivered by the air supply system can flow to the lower air outlet of the support frame.

[0019] In this way, by providing the second opening and closing door, the air flow is controlled to be sent out from the lower air outlet of the support frame, thereby increasing the air output of the lower air outlet of the support frame.

[0020] In some embodiments, the lower air outlet structure further includes a third opening and closing door, which is movably connected to the connecting frame and is used to open or close the passage between the connecting frame and the supporting frame.

[0021] In this way, through the control of the third switch door, when the lower air outlet of the supporting frame does not need to flow out air, the third switch door is used to close the passage opening between the connecting frame and the supporting frame so that the air can all flow out from the first lower air outlet.

[0022] In some embodiments, a pipeline installation structure is further included, and the pipeline installation structure is installed on the lower air outlet structure for installing a refrigerant pipeline and a drainage pipeline.

[0023] In this way, the pipeline installation structure is used to install the refrigerant pipeline and the drainage pipeline, so that the arrangement and installation of the refrigerant pipeline and the drainage pipeline are facilitated by providing the pipeline installation structure.

[0051] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0052] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limiting the present invention.

[0053] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0054] The present invention will be further described in detail below with reference to the accompanying drawings.

[0055] See also Figures 1 to 15 , an air conditioner 100 with a ring-shaped air outlet provided in an embodiment of the present invention includes a body 10 and an air supply system 20.

[0056] See also Figure 1 and Figure 2The body 10 includes a main body 11 and a duct structure 12 arranged in the main body 11. The duct structure 12 has an annular duct 121 and an annular air outlet 122. The annular duct 121 and the annular air outlet 122 are connected to each other. The air supply system 20 is arranged in the main body 11 for supplying air to the annular duct 121.

[0057] The above-mentioned air conditioner 100 with a ring-shaped air outlet is provided with a duct structure 12 in the main body 11, and a ring-shaped air duct 121 is formed in the duct structure 12. Therefore, after air is supplied to the ring-shaped air duct 121 through the air supply system 20, the wind flow can be blown out from the ring-shaped air outlet 122, so that the wind flow is blown toward the user in a ring shape, reducing the user's direct blowing feeling and improving the comfort.

[0058] See also Figures 1 to 3 In one embodiment of the present invention, in order to protect the air duct structure 12 and prevent water droplets from condensing on the surface of the air duct structure 12, the body 10 further includes a front shell 13 and a panel 14. The front shell 13 and the main body 11 encapsulate the air duct structure 12 and the air supply system 20. The front shell 13 has a front opening 131. The front opening 131 is used to allow the airflow of the annular air outlet 122 to flow out. The panel 14 is movably connected to the front shell 13 to open or close the front opening 131, or adjust the size of the annular air outlet 122, so that by setting the front shell 13 and The main body 11 forms an encapsulated space so that the entire air conditioner 100 has overall aesthetics and practicality, and the opening and closing of the front opening 131 is controlled by the panel 14 to protect the annular air outlet 122 to avoid contamination by dust and impurities when not in use; at the same time, by setting the front shell 13 and the panel 14 for shielding, the annular air outlet 122 is prevented from being directly exposed to the air, and dewdrops condense on the surface of the air duct structure 12 due to the higher temperature air contacting the lower temperature air duct structure 12 in the cooling state, and the size of the annular air outlet 122 can be adjusted.

[0059] See also Figure 2 and Figure 3 In one embodiment of the present invention, the air conditioner 100 further includes an upper air outlet structure 30 that is retractable relative to the main body 11. When the upper air outlet structure 30 is in an extended state relative to the main body 11, an upper air outlet 31 is formed. Thus, by setting the retractable upper air outlet structure 30, the upper air outlet 31 can be extended or hidden.

[0060] Among them, in order to achieve air supply at different positions, the body 10 also has a longitudinal air duct 15, which is connected to the annular air duct 121. The air supply system 20 includes an upper air supply mechanism 21 and a lower air supply mechanism 22. The upper air supply mechanism 21 is used to supply air to the upper air outlet 31 and the longitudinal air duct 15, and the lower air supply mechanism 22 is used to supply air to the annular air duct 121. Therefore, by setting the longitudinal air duct 15, the airflow transported by the upper air supply mechanism 21 can pass through the longitudinal air duct 15 and then be transported through the annular air outlet 122 together with the airflow transported by the lower air supply mechanism 22, which can increase the air output of the annular air outlet 122; or the upper air supply mechanism 21 can supply air to the upper air outlet 31 alone; or the lower air supply mechanism 22 can supply air to the annular air outlet 122 alone, so that the air conditioner 100 has a variety of different air supply methods to meet the needs of users.

[0061] Specifically, in order to facilitate the installation of the upper air supply mechanism 21, the air conditioner 100 in this embodiment also includes an upper fixed bracket 40, which is installed on the main body 11 and is used to install and fix the upper air supply mechanism 21, and the upper air outlet structure 30 is telescopic relative to the main body 11 and the upper fixed bracket 40 to realize the opening and closing of the upper air outlet 31.

[0062] It can be understood that in order to facilitate the installation of the lower air supply mechanism 22, the air conditioner 100 in this embodiment also includes a lower fixed bracket 50, which is used to fix the lower air supply mechanism 22, and the lower fixed bracket 50 is installed in the air duct structure 12 and has a longitudinal air cavity 51 facing the annular air duct 121, so that the air flow transported by the lower air supply mechanism 22 flows to the annular air duct 121 after passing through the longitudinal air cavity 51.

[0063] As can be understood, the air conditioner further includes a heat exchange mechanism 60, which is located between the air duct structure 12 and the main body 11. To achieve differentiated air supply, the heat exchange mechanism 60 in this embodiment includes an upper heat exchange portion and a lower heat exchange portion. The heat exchange capacity of the upper heat exchange portion is greater than that of the lower heat exchange portion. For example, the upper heat exchange portion has more heat exchange channels than the lower heat exchange portion, or the refrigerant flow rate entering the upper heat exchange portion is greater than the refrigerant flow rate entering the lower heat exchange portion. Therefore, when cooling or heating, the airflow provided to the upper air supply mechanism 21 is an airflow that has undergone stronger heat exchange, and the airflow provided to the lower air supply mechanism 22 is an airflow that has undergone weaker heat exchange. Therefore, when cooling, the upper air outlet 31 can deliver a cool airflow with a lower temperature, and the lower air outlet 81 and the annular air outlet 122 can deliver a cool airflow with a temperature lower than that of the airflow from the upper air outlet 31, thereby improving user comfort and preventing the lower temperature airflow from directly blowing on the user.

[0064] See also Figure 2 、 Figure 3 and Figure 5In one embodiment of the present invention, in order to ensure that the air flow delivered by the upper air supply mechanism 21 can be quickly heated and then discharged through the annular air outlet 122 in the heating mode, the air conditioner 100 in this embodiment further includes an air inlet cavity structure 70. An air inlet cavity 71 is formed between the air inlet cavity structure 70 and the heat exchange mechanism 60. The upper air supply mechanism 21 is installed in the air inlet cavity 71, and part of the lower air supply mechanism 22 is installed in the air inlet cavity structure 70. The air duct structure 12 has an upper inlet 123 and an upper outlet facing the air inlet cavity structure 70. 124, and an internal channel 125 connecting the upper inlet 123 and the upper outlet 124 is formed inside the air duct structure 12, and the airflow delivered by the upper air supply mechanism 21 can flow to the internal channel 125 through the upper inlet 123 and be blown out from the upper outlet 124, and a longitudinal air duct 72 is formed between the air inlet cavity structure 70 and the air duct structure 12, and the longitudinal air duct 72 is connected to the internal channel 125, so that the airflow delivered by the upper air supply mechanism 21 can flow to the lower air supply mechanism 22 through the longitudinal air duct 72 to be delivered from the annular air outlet 122.

[0065] In addition, this embodiment further includes an air duct adjustment plate 126 to open or close the upper inlet 123 through the air duct adjustment plate 126, thereby controlling whether the wind force of the upper air supply mechanism 21 can flow into the air inlet of the lower air supply mechanism 22.

[0066] Also, see Figure 2 、 Figure 3 as well as Figure 5 In heating mode, when the heat exchange mechanism 60 exchanges heat with the air flow in the air inlet chamber 71, the upper air supply mechanism 21 corresponds to the upper heat exchange part with a stronger heat exchange capacity, which can deliver hot air flow with a higher temperature. However, when the air conditioner is just turned on, the temperature of the heat exchange mechanism 60 cannot quickly reach the required heat exchange temperature. In order to achieve rapid heat exchange of the air flow in heating mode, the air conditioner 100 in this embodiment further includes an auxiliary heat mechanism 90. The auxiliary heat mechanism 90 is provided in the longitudinal air duct 15 and is used to heat the air flow in the initial stage of the heating mode of the air conditioner. The section performs heat exchange on the airflow delivered by the upper air supply mechanism 21, and makes the airflow after heat exchange be delivered from the annular air outlet 122 or at least one lower air outlet 81, so that in the initial stage of the air conditioner being turned on, the airflow after passing through the heat exchange mechanism 60 can pass through the heat exchange of the auxiliary heat mechanism 90 again, so as to improve the heat exchange efficiency through the auxiliary heat mechanism 90, and can quickly provide the user with a hot airflow with a higher temperature, and deliver it from the annular air outlet 122 or the lower air outlet 81, so that the hot airflow with lower density can control the temperature of the environment through its own upward characteristics.

[0067] See also Figure 2 and Figure 3, wherein, in order to control the air inlet and outlet of the lower air supply mechanism 22, the air inlet cavity structure 70 in this embodiment further includes an adjusting structure 73, and the air inlet cavity structure 70 is provided with at least one lower air inlet 74, and the adjusting structure 73 is used to open or close the lower air inlet 74 to control the air inlet of the lower air supply mechanism 22, thereby controlling the air inlet of the lower air supply mechanism 22 by adjusting the structure 73, so as to control the air outlet of the upper air outlet 31 or the annular air outlet 122, for example, closing the lower air inlet 74 and the lower air supply mechanism 22. The upper air outlet 31 is supplied with air only through the upper air supply mechanism 21; or the upper air outlet 31 is closed, and air is taken in through the lower air inlet 74 by the lower air supply mechanism 22 and the upper air supply mechanism 21 is used to supply air to the longitudinal air duct 72, and at the same time, air is supplied to the annular air outlet 122; or the upper air outlet 31 and the upper air supply mechanism 21 are closed, and air is supplied to the annular air outlet 122 only through the lower air inlet 74 by the lower air supply mechanism 22. Users can use it in different ways according to their needs.

[0068] Specifically, the lower air inlet 74 in this embodiment includes two side air inlets 741 located on the left and right sides of the air inlet cavity structure 70 and a rear air inlet 742 facing the heat exchange mechanism 60. At the same time, the three air inlets are opened or closed by adjusting the structure 73, thereby increasing the air intake volume of the lower air supply mechanism 22 by setting air inlets on the left and right sides and the rear side of the air inlet cavity structure 70.

[0069] See also Figures 1 to 5 In one embodiment of the present invention, in order to provide users with more air supply methods, the air conditioner 100 in this embodiment includes a lower air outlet structure 80, which is located below the annular air outlet 122 and is connected to the annular air duct 121 for lower air supply. The lower air outlet structure 80 includes at least one lower air outlet 81, which is used for lower air supply. Therefore, lower air supply is performed through the lower air outlet structure 80, and can cooperate with the upper air outlet 31 and the annular air outlet 122 to supply air, providing users with more air supply methods.

[0070] Specifically, the lower air outlet structure 80 in this embodiment has multiple lower air outlets 81, and the multiple lower air outlets 81 are arranged in sequence from top to bottom. When heating, the upward characteristic of the air flow is used to control the temperature of the environment. By arranging the multiple lower air outlets 81 up and down, different lower air outlets 81 can be selectively used according to the height of the obstacles on the supporting surface. For example, a lower air outlet 81 at a higher position can be used to achieve the effect of avoiding obstacles, so that the wind can flow to a farther location.

[0071] Among them, the lower air outlet structure 80 in this embodiment includes a connecting frame 82 and a supporting frame 83, and the connecting frame 82 and the supporting frame 83 respectively form at least one lower air outlet 81, and the connecting frame 82 is connected between the air duct structure 12 and the supporting frame 83, and the connecting frame 82, the annular air duct 121 and the supporting frame 83 can be interconnected so that the airflow provided by the air supply system 20 can flow from top to bottom, so that by setting different structural parts of the connecting frame 82 and the supporting frame 83, it is possible to control whether the lower air outlet 81 set in each part discharges air, and it is possible to control the opening position of the lower air outlet 81 on each part.

[0072] Specifically, see Figure 4 、 Figure 6 as well as Figure 7 To facilitate smooth flow of air provided by the air supply system 20 to the lower air outlet structure 80, the air duct structure 12 in this embodiment includes a first switch door 127. The first switch door 127 is used to open or close the annular air duct 121. When the annular air duct 121 is closed, the air supplied by the air supply system 20 flows to the lower air outlet structure 80. By providing the first switch door 127 to close the annular air duct 121, the air supply provided by the lower air supply mechanism 22 can be controlled to flow entirely to the lower air outlet structure 80, allowing the lower air outlet structure 80 to retain a larger amount of airflow. Alternatively, in other usage modes, when the first switch door 127 is open, the air supply provided by the air supply system 20 can flow not only from the annular air outlet 122 but also from each of the lower air outlets 81.

[0073] Among them, see Figure 1 and Figure 2 In this embodiment, the connecting frame 82 is provided with a lower air outlet 81, which is the first lower air outlet. Specifically, the first lower air outlet has a first outlet portion 811 and a second outlet portion 812. The first outlet portion 811 faces the supporting frame 83. The first outlet portion 811 and the second outlet portion 812 are connected to each other so that the airflow delivered from the first outlet portion 811 can be delivered from the second outlet portion 812.

[0074] Specifically, in this embodiment, the second outlet 812, the annular air outlet 122, and the upper air outlet 31 face the same side of the main body 11, specifically, toward the front of the air conditioner. Thus, by configuring the first lower air outlet to include a first outlet 811 and a second outlet 812, airflow flows downward from the first outlet 811 and then turns to flow out of the second outlet 812, providing the air conditioner with a variety of air outlet options and achieving diversified development of air conditioner structures.

[0075] It can be understood that in order to ensure that the wind flow delivered from the first outlet portion 811 can be smoothly blown out from the second outlet portion 812, a guide structure 831 is provided on the side of the support frame 83 facing the connecting frame 82. The guide structure 831 is used to guide the wind flow blown out of the first outlet portion 811 to the second outlet portion 812. By setting the guide structure 831, the loss of the wind flow blown out from the first outlet portion 811 can be reduced, and the flow rate of the wind flow delivered from the second outlet portion 812 can be increased.

[0076] Specifically, the cross-sectional area of ​​the second outlet portion 812 in this embodiment gradually increases from the left side to the right side of the air conditioner 100 , thereby ensuring the flow rate of the airflow at the second outlet portion 812 .

[0077] See also Figure 8 and Figure 9 In one embodiment of the present invention, when the lower air outlet structure 80 is used for air outlet, in order to control the use of different air outlets in the lower air outlet structure 80, the lower air outlet structure 80 also includes a second switch door 84, and the second switch door 84 is movably connected to the connecting frame 82, and is used to open or close the first outlet portion 811, so that when the first outlet portion 811 is in a closed state, the airflow delivered by the air supply system 20 flows to the lower air outlet 81 of the support frame 83, so that by setting the second switch door 84, the airflow is controlled to be delivered from the lower air outlet 81 of the support frame 83, thereby increasing the air outlet volume of the lower air outlet 81 of the support frame 83.

[0078] The support frame 83 in this embodiment is provided with a lower air outlet 81 , which is the second air outlet. The second air outlet, the second outlet portion 812 and the annular air outlet 122 are located on the same side of the air conditioner.

[0079] It can be understood that in order to be able to control the airflow delivered to the lower air outlet structure 80 by the air supply system 20 so that it can be delivered out from the first air outlet, the lower air outlet structure 80 in this embodiment also includes a third switch door 85, and the third switch door 85 is movably connected relative to the connecting frame 82, and is used to open or close the channel opening 821 between the connecting frame 82 and the support frame 83, so that through the control of the third switch door 85, when the lower air outlet 81 of the support frame 83 does not need to flow out airflow, the third switch door 85 is used to close the channel opening 821 between the connecting frame 82 and the support frame 83, so that the airflow can all flow out from the first lower air outlet.

[0080] See also Figure 2 and Figure 3In one embodiment of the present invention, in order to facilitate the installation of pipes, the air conditioner 100 in this embodiment also includes a pipe installation structure 200. The pipe installation structure 200 is installed on the lower air outlet structure 80 and is used to install refrigerant pipes and drainage pipes. The arrangement of the refrigerant pipes and drainage pipes is facilitated by setting the pipe installation structure 200.

[0081] Specifically, the pipe installation structure 200 in this embodiment is installed in the connecting frame 82 so that the refrigerant pipe and the drainage pipe can be arranged and then go out of the supporting frame 83 .

[0082] See also Figures 10 to 15 , which introduces some usage methods of the air conditioner in the embodiments of the present invention.

[0083] For example, in cooling mode, see Figure 10 When air is discharged through the upper air outlet 31, it corresponds to the forced cooling mode; for example Figure 11 , the lower air supply mechanism 22 can also be used to supply air to the annular air outlet 122 to achieve forced cooling in the upper part and comfortable air outlet in the middle; for example Figure 12 , and the lower air supply mechanism 22 can also be used to supply air to the lower air outlet 81 to achieve full-area air outlet.

[0084] For example, in heating mode, see Figure 13 and Figure 14 In the first stage, the upper air outlet 31 and the lower air supply mechanism 22 are closed, and the air flow delivered by the upper air supply mechanism 21 passes through the longitudinal air duct 15 and the auxiliary heating mechanism 90 and then passes through the lower air supply mechanism 22 to be delivered. It can be delivered through the annular air outlet 122 or through the lower air outlet 81; please refer to Figure 15 When the heat exchange mechanism 60 reaches a certain temperature, the auxiliary heat mechanism 90 can be turned off and the lower air supply mechanism 22 can be turned on, so that the airflow sucked in by the upper air supply mechanism 21 and the lower air supply mechanism 22 can be delivered from the annular air outlet 122 or the lower air outlet 81. Alternatively, in other embodiments, the upper air outlet 31, the annular air outlet 122, and each of the lower air outlets 81 are all in the open state, thereby achieving full-area air supply of the air conditioner 100.
