Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and more particularly, to an air conditioner. Background Art

[0002] Air conditioners such as ceiling-mounted units have a simple structure, generally with bottom air return and side air outlet in such a structural form. During use, the fan sucks indoor air from the center position at the bottom, flows through the heat exchanger, and then sends it out from the side, thereby heating or cooling the indoor air to achieve the effect of regulating the indoor temperature.

[0003] In particular, since a large-sized air return opening is provided at the bottom of the air conditioner, this directly causes the user to easily observe the air return opening during daily use, affecting the aesthetic degree of the air conditioner. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0005] To this end, the present invention provides an air conditioner.

[0006] The present invention provides an air conditioner, including: a housing, the housing includes a connected housing body and a shielding member, a fan chamber is provided inside the housing body, a flow-through opening is provided at the bottom of the fan chamber, and the shielding member is located at the bottom of the flow-through opening; a heat exchanger, provided inside the housing body and located outside the fan chamber; a fan, provided inside the fan chamber and located on top of the shielding member; an air return opening, provided on the housing body, the air return opening is connected to the fan chamber through the flow-through opening and opens towards the side of the housing body; an air outlet, provided on the housing body and connected to the fan chamber.

[0007] The air conditioner proposed by the present invention includes a housing, a heat exchanger, a fan, an air return opening, and an air outlet. Among them, the housing includes a connected housing body and a shielding member, an internal fan chamber is provided in the housing body, the fan is provided in the fan chamber, a flow-through opening is provided at the bottom of the fan chamber, and the shielding member is located at the bottom of the fan chamber and the flow-through opening to shield the bottom of the housing body and the flow-through opening; the heat exchanger is provided inside the housing body and located outside the fan chamber, and the heat exchanger can exchange heat with the air flow during the operation of the air conditioner to achieve the refrigeration and heating effects of the air conditioner.

[0008] In addition, the air return opening and the air outlet are arranged on the housing body and can be respectively communicated with the fan chamber; during the operation of the air conditioner, the external air flow enters the fan chamber from the air return opening and the flow-through opening under the drive of the fan, and then is discharged from the air outlet. In particular, compared with the implementation manner of opening a large-sized air return opening at the bottom of the housing in the related art, in the present invention, the air return opening is opened toward the side of the housing body, and the flow-through opening is blocked by a blocking member, so that the present application can avoid arranging a large-sized opening on the bottom wall of the air conditioner. Therefore, after the air conditioner is installed, when the user observes the air conditioner from the bottom of the air conditioner, there will be no large-sized air return opening, which greatly improves the aesthetic degree of the air conditioner.

[0009] Specifically, the air conditioner proposed by the present invention can be a ceiling-mounted air conditioner and is installed on the ceiling during daily use. Generally, the user can only observe the bottom of the air conditioner. In the related art, the air return opening is arranged on the bottom wall of the air conditioner, which causes the user to directly observe that there is a hollow area at the bottom of the air conditioner, affecting the aesthetic degree of the air conditioner. The present invention optimizes the opening direction of the air return opening, so that the air return opening is opened toward the side of the housing body, and the flow-through opening at the bottom of the fan chamber is blocked by a blocking member. In this way, after the air conditioner is installed, the user will not observe the air return opening on the side of the housing body, nor will the user observe the flow-through opening at the bottom of the fan chamber. On the one hand, side air return of the air conditioner is realized, and on the other hand, the aesthetic degree of the air conditioner is improved.

[0010] Furthermore, the air outlet can be opened toward the side and / or the bottom of the housing body. When the air outlet is opened toward the side of the housing body, the user cannot observe the air outlet on the side of the housing body either; when the air outlet is opened toward the bottom of the housing body, a normally closed component (such as a check valve) can be arranged at the air outlet. In this way, the air outlet can still be blocked when the user is in the standby state; even when the air conditioner needs to open the air outlet during operation, the aesthetic degree of the air conditioner is also improved to a certain extent.

[0011] Even further, the blocking member is located at the bottom of the fan chamber and can be used to block the fan chamber and the flow-through opening arranged at the bottom of the fan chamber. At the same time, other functional components can be arranged on the blocking member, or the wall surface of the blocking member can be beautified, further improving the aesthetic degree of the entire bottom of the air conditioner. And the blocking member can reduce the noise propagation during the operation of the air conditioner to a certain extent, and thus play a role in noise reduction to a certain extent, improving the comfort of the air conditioner during use.

[0012] Therefore, the air conditioner proposed by the present invention optimizes the opening direction of the air return opening and blocks the flow-through opening at the bottom of the fan chamber by a blocking member. After the air conditioner is installed, the user will not observe the air return opening on the side of the housing body and the flow-through opening at the bottom of the fan chamber, improving the aesthetic degree of the air conditioner. The fan chamber can also be blocked by the blocking member, and various uses of the blocking member can be realized.

Detailed implementation manner

[0056] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0057] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0058] The following refers to Figures 1 to 20 to describe an air conditioner provided according to some embodiments of the present invention.

[0059] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a first embodiment of the present invention provides an air conditioner, including: a housing 102, a heat exchanger 110, a fan 112, an air return opening 114 and an air outlet 116.

[0060] Among them, as Figure 1 and Figure 2 shown, the housing 102 includes a connected housing body 104 and a shielding member 106. The interior of the housing body 104 is a fan chamber 108, and the fan 112 is disposed in the fan chamber 108. The shielding member 106 is located at the bottom of the fan chamber 108. A flow-through opening 122 is provided at the bottom of the fan chamber 108 to shield the bottom of the housing body 104 and the flow-through opening 122; the heat exchanger 110 is disposed in the housing body 104, outside the fan chamber 108, and can exchange heat with the air flow during the operation of the air conditioner to achieve the cooling and heating effects of the air conditioner.

[0061] In addition, the air return opening 114 and the air outlet 116 are provided on the housing body 104 and can be respectively communicated with the blower chamber 108; during the operation of the air conditioner, the external air flow enters the blower chamber 108 from the air return opening 114 and the flow-through opening 122 under the drive of the blower 112, and then is discharged from the air outlet 116. In particular, compared with the implementation manner in the related art where a large-sized air return opening 114 is provided at the bottom of the housing 102, in the present invention, the air return opening 114 opens toward the side of the housing body 104, and the flow-through opening 122 is blocked by the blocking member 106, so that the present application can avoid providing a large-sized opening on the bottom wall of the air conditioner. Therefore, as Figure 4 shown, after the air conditioner is installed, when the user observes the air conditioner from the bottom of the air conditioner, there will be no large-sized air return opening 114, which greatly improves the aesthetic degree of the air conditioner.

[0062] Specifically, the air conditioner proposed in this embodiment can be a ceiling-mounted air conditioner and is installed on the ceiling during daily use. Generally, the user can only observe the bottom of the air conditioner. In the related art, the air return opening is provided on the bottom wall of the air conditioner, which causes the user to directly observe that there is a hollow area at the bottom of the air conditioner, affecting the aesthetic degree of the air conditioner. The present invention optimizes the opening direction of the air return opening 114 so that the air return opening 114 opens toward the side of the housing body 104, and the flow-through opening 122 at the bottom of the blower chamber 108 is blocked by the blocking member 106. In this way, after the air conditioner is installed, the user will not observe the air return opening 114 on the side of the housing body 104, nor will the user observe the flow-through opening 122 at the bottom of the blower chamber 108. On the one hand, the side air return of the air conditioner is realized, and on the other hand, the aesthetic degree of the air conditioner is improved.

[0063] Furthermore, the air outlet 116 can open toward the side and / or the bottom of the housing body 104. When the air outlet 116 opens toward the side of the housing body 104, the user cannot observe the air outlet 116 on the side of the housing body 104 either; when the air outlet 116 opens toward the bottom of the housing body 104, a normally closed component (such as a check valve) can be provided at the air outlet 116. In this way, the air outlet 116 can still be blocked when the user is in the standby state; even when the air conditioner needs to open the air outlet 116 during operation, the aesthetic degree of the air conditioner is also improved to a certain extent.

[0064] Even further, as Figure 1 and Figure 2As shown, the shielding member 106 is located at the bottom of the blower chamber 108 and can be used to shield the blower chamber 108 and the flow-through port 122 provided at the bottom of the blower chamber 108. At the same time, other functional components can be provided on the shielding member 106, or the wall surface of the shielding member 106 can be beautified, further improving the aesthetic degree of the bottom of the entire air conditioner. Moreover, the shielding member 106 can reduce the noise transmission during the operation of the air conditioner to a certain extent, thereby playing a role in noise reduction to a certain extent and improving the comfort of the air conditioner during use.

[0065] Therefore, the air conditioner proposed in this embodiment optimizes the opening direction of the air return port 114. After the air conditioner is installed, the user will not observe the air return port 114 located on the side of the housing body 104, improving the aesthetic degree of the air conditioner. The blower chamber 108 can also be shielded by the shielding member 106, and various uses of the shielding member 106 can be realized.

[0066] The second embodiment of the present invention proposes an air conditioner. On the basis of the first embodiment, further:

[0067] As Figure 1 and Figure 2 shown, the shielding member 106 includes a shielding plate. Among them, the shielding plate is connected to the housing body 104 and is located at the bottom of the blower chamber 108. In this way, after the air conditioner is installed, the shielding plate is located below the blower chamber 108 to play a shielding role, so that the user cannot observe the blower chamber 108 and cannot observe the communication port provided on the bottom plate 130 of the blower chamber 108, playing a role in beautifying the air conditioner.

[0068] In this embodiment, further, as Figure 2 shown, the shielding member 106 is a fixed plate. That is, the shielding plate is fixedly connected to the housing body 104. In this way, the structure of the shielding plate and the entire housing 102 can be effectively simplified. Especially compared with the rotating plate body used in the related art, the shielding member 106 in the present invention can play a shielding role without bringing difficulty to the installation and assembly of the air conditioner, and at the same time can reduce the cost of the air conditioner.

[0069] It should be noted here that the shielding member 106 being a fixed plate means that after the shielding member 106 is installed, the shielding member 106 will not rotate or move relative to the housing body 104, so as to ensure the stable connection between the shielding member 106 and the housing body 104. However, the shielding member 106 and the housing body 104 can be detachably connected, and the shielding member 106 and the housing body 104 can also be an integral structure, which is not limited here.

[0070] The third embodiment of the present invention proposes an air conditioner. On the basis of the first embodiment, further:

[0071] AsFigure 1 and Figure 3 As shown, there is a return air channel 120 between the bottom plate 130 of the housing body 104 and the shielding member 106, and a flow-through opening 122 is provided on the bottom plate 130 of the housing body 104. Among them, the return air channel 120 is connected to the external environment through the return air opening 114, the return air channel 120 is connected to the blower chamber 108 through the flow-through opening 122, and the blower chamber 108 is connected to the external environment through the air outlet 116. In this way, during the operation of the air conditioner, the external air flow can first enter the return air channel 120 through the return air opening 114, the air flow in the return air channel 120 can enter the interior of the blower chamber 108 through the flow-through opening 122, and the air flow in the blower chamber 108 is pressurized by the blower 112 and then flows out from the air outlet 116.

[0072] That is to say, during the operation of the air conditioner, the external air flow can first enter the return air channel 120 through the return air opening 114, and then enter the interior of the blower chamber 108 through the flow-through opening 122; the air flow in the blower chamber 108 is pressurized by the blower 112, exchanges heat with the heat exchanger 110 and is discharged from the air outlet 116. There is no obstruction in the whole air flow process, which can ensure the orderly flow of the air flow and ensure the flow rate and flow volume of the air flow.

[0073] In particular, as Figure 1 shown, a flow-through opening 122 is provided on the bottom plate 130 of the housing body 104, and there is a return air channel 120 between the bottom plate 130 of the housing body 104 and the shielding member 106. In this way, it is ensured that the shielding member 106 is at the bottom of the flow-through opening 122 and the return air channel 120. After the air conditioner is installed, the shielding member 106 can effectively shield the flow-through opening 122 and the return air channel 120, ensuring that the flow-through opening 122 is not exposed at the bottom of the air conditioner, thereby effectively improving the aesthetic degree of the air conditioner.

[0074] In addition, since the flow-through opening 122 has been shielded by the shielding member 106, no matter how large the area of the flow-through opening 122 is opened, it will not affect the aesthetic degree of the air conditioner. Therefore, a large-sized flow-through opening 122 can be provided to ensure its flow-through area, so that the air conditioner proposed in this embodiment has both aesthetics and high-efficiency air supply capacity.

[0075] The fourth embodiment of the present invention proposes an air conditioner, on the basis of the first embodiment, further:

[0076] As Figure 1 and Figure 3As shown, an air outlet passage 124 is provided on the housing body 104. Among them, the blower chamber 108 is communicated with the air outlet 116 through the air outlet passage 124, so as to ensure that the air flow in the blower chamber 108 passes through the air outlet passage 124 and is discharged from the air outlet 116. In addition, due to the setting of the air outlet passage 124, the air outlet of the air conditioner is carried out in the air outlet passage 124, while the air return of the air conditioner is carried out in the air return passage 120. The air outlet passage 124 and the air return passage 120 are independent of each other and will not affect each other, thus ensuring the orderly air return and air outlet of the air conditioner. And, due to the setting of the air outlet passage 124, it is ensured that the setting position of the air outlet 116 has a great degree of freedom, reducing the limitation of the setting position of the air outlet 116.

[0077] In this embodiment, further, as Figure 1 and Figure 3 shown, the number of the air outlet passages 124 is multiple. Among them, the multiple air outlet passages 124 are distributed along the circumferential direction of the housing body 104. In this way, during the use of the air conditioner, the air flow in the blower chamber 108 flows through the multiple air outlet passages 124 to the air outlet 116 at the same time and is discharged from the air outlet 116. And the above-mentioned multiple air outlet passages 124 are distributed along the circumferential direction of the housing body 104, so as to realize the circumferential air outlet or annular air outlet of the air conditioner, further improving the air outlet effect of the air conditioner.

[0078] In this embodiment, further, as Figure 1 and Figure 3 shown, the number of the air return openings 114 is multiple. Among them, the multiple air return openings 114 are distributed along the circumferential direction of the housing body 104. In this way, during the use of the air conditioner, the external air flow enters the air return passage 120 through the multiple air return openings 114 at the same time and enters the blower chamber 108 through the air flow through openings 122 provided on the shielding member 106. And the above-mentioned multiple air return openings 114 are distributed along the circumferential direction of the housing body 104, so as to realize the circumferential air return of the air conditioner, further improving the air return effect of the air conditioner.

[0079] In this embodiment, further, as Figure 1 and Figure 3 shown, along the circumferential direction of the housing body 104, the multiple air return openings 114 and the multiple air outlet passages 124 are alternately distributed. In this way, it can ensure the positions of the multiple air return openings 114 and the multiple air outlet passages 124 along the circumferential direction of the housing body 104, ensure the uniform air return and air outlet of the air conditioner, and ensure that the air conditioner can return air from the side of the housing body 104 and realize the circumferential air outlet or annular air outlet of the air conditioner.

[0080] In a specific embodiment, there is a certain gap between two adjacent air outlet channels 124, and it is ensured that the gap between two connected air outlet channels 124 forms the above-mentioned air return opening 114. Among them, the size of the gap between two connected air outlet channels 124 can be designed according to actual conditions to ensure the air return area of the air return opening 114.

[0081] In this embodiment, further, as Figure 1 and Figure 3 shown, the air outlet 116 includes an annular air outlet (i.e., the first sub-air outlet 126). Among them, a plurality of air outlet channels 124 communicate with the annular air outlet, and it can be ensured that the plurality of air outlet channels 124 are evenly communicated along the circumferential direction of the annular air outlet. In this way, during the operation of the air conditioner, the air flow in the fan cavity 108 simultaneously and evenly flows towards the annular air outlet through the plurality of air outlet channels 124, and then is discharged from the annular air outlet to ensure the uniformity of the air outlet of the air conditioner.

[0082] The fifth embodiment of the present invention proposes an air conditioner, which further:

[0083] As Figure 1 and Figure 3 shown, the air return opening 114 is arranged on the side plate 132 of the housing body 104, and the air return opening 114 opens towards the side of the housing body 104. In this way, after the air conditioner is installed, when the user observes the air conditioner from the bottom of the air conditioner, there will be no large-sized air return opening 114, which greatly improves the aesthetic degree of the air conditioner.

[0084] Specifically, in this embodiment, the air return opening 114 is opened on the side plate 132 of the housing body 104, and it is ensured that the air return opening 114 opens towards the side of the housing body 104. In this way, after the air conditioner is installed, when the user observes the air conditioner from the bottom of the air conditioner, there will be no large-sized air return opening 114, which greatly improves the aesthetic degree of the air conditioner.

[0085] The sixth embodiment of the present invention proposes an air conditioner, which further:

[0086] The air outlet 116 includes a first sub-air outlet 126 and a second sub-air outlet 128. Among them, the first sub-air outlet 126 is arranged on the housing body 104 and opens towards the side of the housing body 104, and the second sub-air outlet 128 is arranged on the housing body 104 and opens towards the bottom of the housing body 104. In addition, the air conditioner further includes a conduction component, which is arranged on the housing body 104 and can open or close the first sub-air outlet 126 and open or close the second sub-air outlet 128 during the operation of the air conditioner, so that the air conditioner blows air from the first sub-air outlet 126 or the second sub-air outlet 128.

[0087] In this way, through the cooperation of the above-mentioned first sub-air outlet 126, second sub-air outlet 128 and the conduction component, various air outlet modes of the air conditioner can be realized, so that the air conditioner can better meet different usage requirements in scenarios such as cooling and heating.

[0088] Specifically, as Figure 5 , Figure 6 , Figure 7 and Figure 8 show, when the air conditioner operates in the cooling mode, the conduction component controls the first sub-air outlet 126 to be in the open state and the second sub-air outlet 128 to be in the closed state. At this time, the external air flow enters the fan cavity 108 from the return air outlet 114, and after heat exchange, it is discharged from the first sub-air outlet 126 opening towards the side of the housing body 104. At this time, the air conditioner operates in the cooling mode, and the air flow blown out from the first sub-air outlet 126 has a relatively low temperature, and the relatively low-temperature air flow blows towards the side of the air conditioner and does not directly blow towards the user, improving the comfort of the user using the air conditioner.

[0089] Specifically, as Figure 9 , Figure 10 , Figure 11 and Figure 12 show, when the air conditioner operates in the heating mode, the conduction component controls the second sub-air outlet 128 to be in the open state and the first sub-air outlet 126 to be in the closed state. At this time, the external air flow enters the fan cavity 108 from the return air outlet 114, and after heat exchange, it is discharged from the second sub-air outlet 128 opening towards the bottom of the housing body 104. At this time, the air conditioner operates in the heating mode, and the air flow blown out from the second sub-air outlet 128 has a relatively high temperature, and the relatively high-temperature air flow blows towards the bottom of the air conditioner and directly acts on the user's feet to realize the warm-foot function of the air conditioner.

[0090] Therefore, the air conditioner proposed in this embodiment has various air outlet effects. It can blow air towards the side when operating in the cooling mode and blow air towards the bottom when operating in the heating mode. It can avoid the cold air directly acting on the user and can also realize the warm-foot function of the air conditioner, so that the air conditioner can meet different requirements in different scenarios.

[0091] In this embodiment, further, as Figure 1 shows, the bottom plate 130 of the housing body 104 is provided with an extension edge 134, and at least part of the extension edge 134 extends towards the peripheral side of the housing body 104, and the peripheral edge of the extension edge 134 is located at the bottom of the side plate 132 of the housing body 104. In addition, as Figure 1As shown, the first sub-air outlet 126 is located on the side plate 132 of the housing body 104, or the first sub-air outlet 126 is located between the side plate 132 and the extension edge 134 of the housing body 104. In this way, it can be ensured that the first sub-air outlet 126 opens towards the side of the housing body 104, so that when the air conditioner operates in the cooling mode, the cold air can be guided to the side of the housing body 104, preventing the cold air from directly blowing on the user and causing discomfort to the user.

[0092] Specifically, when the first sub-air outlet 126 is located on the side plate 132 of the housing body 104, the above-mentioned first sub-air outlet 126 can be directly formed when manufacturing the side plate 132 of the housing body 104; when the first sub-air outlet 126 is located between the side plate 132 and the extension edge 134 of the housing body 104, a certain distance can be reserved between the side plate 132 and the extension edge 134 of the housing body 104 during the assembly process of the air conditioner, so as to directly form the above-mentioned first sub-air outlet 126 through the gap between the side plate 132 and the extension edge 134 of the housing body 104.

[0093] In addition, as Figure 1 shown, the second sub-air outlet 128 is located on the extension edge 134 to ensure that the second sub-air outlet 128 blows air towards the bottom of the housing body 104. And the second sub-air outlet 128 is in a normally closed state. That is, only when the air conditioner operates in the heating mode, the second sub-air outlet 128 will be in an open state. In this way, while ensuring that the second sub-air outlet 128 opens towards the bottom of the housing body 104, the second sub-air outlet 128 can be hidden when the air conditioner is not operating or operating in the heating mode, so that the user cannot observe the second sub-air outlet 128 from the bottom, greatly improving the aesthetic degree of the appearance surface of the air conditioner.

[0094] The seventh embodiment of the present invention proposes an air conditioner, which further:

[0095] As Figure 1 shown, the conduction assembly includes a switch assembly 136 and an elastic conduction member 138. Among them, the switch assembly 136 is disposed at the first sub-air outlet 126 in a liftable manner and can be used to open or close the first sub-air outlet 126; the elastic conduction member 138 is disposed at the second sub-air outlet 128, and the elastic conduction member 138 is a normally closed element. When the switch assembly 136 closes the first sub-air outlet 126, the elastic conduction member 138 will open the second sub-air outlet 128.

[0096] Specifically, as Figure 8As shown, when the air conditioner operates in the cooling mode, the switch assembly 136 opens the first sub-air outlet 126, and the elastic conduction member 138 closes the second sub-air outlet 128. At this time, the external air flow enters the fan chamber 108 from the air return opening 114, and after heat exchange, it is discharged from the first sub-air outlet 126 that opens to the side of the housing body 104. When the air conditioner operates in the cooling mode, the air flow blown out from the first sub-air outlet 126 has a relatively low temperature, and the relatively low-temperature air flow is blown out towards the side of the air conditioner, without directly blowing towards the user, thus improving the comfort of the user when using the air conditioner.

[0097] Specifically, as Figure 12 shown, when the air conditioner operates in the heating mode, the switch assembly 136 closes the first sub-air outlet 126, and the air flow continuously accumulates in the air duct in the fan chamber 108, so that the air pressure in the fan chamber 108 increases, and the elastic conduction member 138 is driven by the air pressure difference to open the second sub-air outlet 128. At this time, the external air flow enters the fan chamber 108 from the air return opening 114, and after heat exchange, it is discharged from the second sub-air outlet 128 that opens to the bottom of the housing body 104. At this time, when the air conditioner operates in the heating mode, the air flow blown out from the second sub-air outlet 128 has a relatively high temperature, and the relatively high-temperature air flow is blown out towards the bottom of the air conditioner, directly acting on the user's feet to realize the warm-foot function of the air conditioner.

[0098] In addition, as Figure 13 、 Figure 14 、 Figure 15 、 Figure 16 shown, whether the air conditioner is in the cooling mode or the heating mode, when a wider air outlet angle of the air conditioner needs to be achieved, the switch assembly 136 controls the first sub-air outlet 126 to be in a semi-open and semi-closed state. At this time, the external air flow enters the fan chamber 108 from the air return opening 114, and after heat exchange, a part of it is discharged from the first sub-air outlet 126, and the other part in the fan chamber 108 will cause the air pressure in the fan chamber 108 to increase, so that the elastic conduction member 138 is driven by the air pressure difference to open the second sub-air outlet 128, making the second sub-air outlet 128 in a semi-open and semi-closed state, and then enabling the other part of the air flow to be discharged through the second sub-air outlet 128. At this time, the air conditioner can blow air towards the side and towards the bottom, achieving a wider air outlet effect.

[0099] In addition, the switch assembly 136 can also control the first sub-air outlet 126 to intermittently open and close the first sub-air outlet 126. At this time, the air conditioner can achieve oscillating air supply.

[0100] Therefore, in this embodiment, the elastic conduction member 138 is in a normally closed state and can close the second sub-air outlet 128; when the switch assembly 136 closes the first sub-air outlet 126, the elastic conduction member 138 will open the second sub-air outlet 128 under the action of air pressure; when the air conditioner ends operation, the elastic conduction member 138 can continue to close the second sub-air outlet 128. In a specific embodiment, the elastic conduction member 138 can adopt a check valve.

[0101] In this embodiment, further, as Figure 17 , Figure 18 , Figure 19 , Figure 20 shown, the switch assembly 136 includes a baffle 140 and a driving member 142. Among them, the driving member 142 is arranged on the housing body 104, and the baffle 140 is arranged at the first sub-air outlet 126 in a liftable manner; the driving member 142 is connected to the baffle 140 and can be used to drive the baffle 140 to lift or lower to open or close the first sub-air outlet 126.

[0102] In particular, the method of driving the baffle 140 to lift or lower by the driving member 142 to open or close the first sub-air outlet 126 can ensure the conduction area of the first sub-air outlet 126 compared with the rotation driving method adopted in the related art. And, due to the limitation of the above-mentioned lift driving method, there is no rotating shaft in this application, which enables the air outlet 116 in this application to be a common arc-shaped air outlet 116 (both the first sub-air outlet 126 and the second sub-air outlet 128 can adopt the arc-shaped air outlet 116), so that the air conditioner has better air supply uniformity and a wider air supply range.

[0103] In a specific embodiment, as Figure 17 , Figure 18 , Figure 19 , Figure 20 shown, the driving member 142 adopts a motor, and the motor drives the baffle 140 to lift or lower in a gear-rack manner. Specifically, a rack is arranged on the baffle 140, a gear is arranged on the output shaft of the motor, and the gear meshes with the rack on the baffle 140. When it is necessary to open the first sub-air outlet 126 by the switch assembly 136, the motor drives the gear to rotate in the first direction, and then drives the baffle 140 to rise and open the first sub-air outlet through the cooperation of the gear and the rack; when it is necessary to open the first sub-air outlet 126 by the switch assembly 136, the motor drives the gear to rotate in the second direction, and then drives the baffle 140 to descend and close the first sub-air outlet through the cooperation of the gear and the rack. Among them, the first direction and the second direction are opposite.

[0104] On the basis of Embodiment Six and Embodiment Seven, further, as Figure 1As shown, the first sub-air outlet 126 is an annular air outlet. In this way, when the air conditioner operates in the cooling mode, air can be discharged annularly from the peripheral side of the housing body 104. In this way, the shape of the first sub-air outlet 126 matches that of the fan 112, and the distance from the first sub-air outlet 126 to the fan 112 is ensured to be equal. During the air operation, after being pressurized by the fan 112, the air flow simultaneously flows towards the first sub-air outlets 126 on the peripheral side, and the distance from the first sub-air outlet 126 to the fan 112 is equal, ensuring that the air flow has the same flow velocity when reaching different positions of the first sub-air outlet 126, making the flow velocity of the air flow discharged from the first sub-air outlet 126 uniform and achieving a better air supply effect of the air conditioner.

[0105] On the basis of Embodiment Six and Embodiment Seven, further, the second sub-air outlet 128 is an annular air outlet. In this way, when the air conditioner operates in the heating mode, air can be discharged annularly from the peripheral side of the housing body 104. In this way, the shape of the second sub-air outlet 128 matches that of the fan 112, and the distance from the second sub-air outlet 128 to the fan 112 is ensured to be equal. During the air operation, after being pressurized by the fan 112, the air flow simultaneously flows towards the second sub-air outlets 128 on the peripheral side, and the distance from the second sub-air outlet 128 to the fan 112 is equal, ensuring that the air flow has the same flow velocity when reaching different positions of the second sub-air outlet 128, making the flow velocity of the air flow discharged from the second sub-air outlet 128 uniform and achieving a better air supply effect of the air conditioner.

[0106] In addition, in another embodiment, the second sub-air outlet 128 can also be set as an arc-shaped air outlet 116, and a plurality of arc-shaped air outlets 116 are distributed along the axial direction of the housing body 104.

[0107] On the basis of Embodiments One to Seven, further, as Figure 1 shown, the heat exchanger 110 is an annular heat exchanger 110. Among them, the annular heat exchanger 110 is arranged on the peripheral side of the fan 112 to ensure that the distance from the fan 112 to the annular heat exchanger 110 is equal. In this way, during the operation of the air conditioner, the air flow pressurized by the fan 112 will pass through the annular heat exchanger 110 and be heat-exchanged. In addition, the annular heat exchanger 110 enables the air conditioner to have a larger heat exchange area and better heat exchange uniformity. During the use of the air conditioner, the air flows at different positions are heat-exchanged with different positions of the heat exchanger 110, and then the air flows at different positions are simultaneously discharged from different positions of the annular air outlet, achieving the uniformity of air supply and the uniformity of air temperature.

[0108] On the basis of Embodiments One to Seven, further, as Figure 1As shown, the housing 102 is an annular housing 102. Thus, the annular housing 102 matches the annular heat exchanger 110 and the annular air outlet. Furthermore, compared to the square housing 102 used in related art, the distance from the side panels 132 of the heat exchange housing 102 to the center of the fan 112 is equal. This ensures a consistent flow rate of air from the center of the sub-fan 112 to the side panels 132 of the heat exchange housing 102, achieving uniform heat exchange for the air conditioner.

[0109] On the basis of the first to seventh embodiments, further, as Figure 1 As shown, the fan 112 is a centrifugal fan 112 , wherein the annular heat exchanger 110 is arranged on the radial circumference side of the centrifugal fan 112 , and the return air inlet 114 is arranged at the bottom of the centrifugal fan 112 in the axial direction.

[0110] On the basis of the first to seventh embodiments, further, as Figure 1 As shown, a mounting position 144 is provided on the shielding member 106. The mounting position 144 can be used to mount functional components to realize the multi-function of the air conditioner. Specifically, the functional components include but are not limited to lighting lamps and the like.

[0111] On the basis of the first to seventh embodiments, further, as Figure 1 As shown, the return air inlet 114 and the air outlet 116 are both arranged near the bottom of the shell body 104 , and the return air inlet 114 is arranged higher than the air outlet 116 .

[0112] On the basis of the first to seventh embodiments, further, as Figure 1 As shown, an air guide 146 is provided on the side panel 132 of the housing body 104, and the air guide 146 is located between the return air inlet 114 and the air outlet 116. The air guide 146 can play a good wind blocking role at the position of the return air inlet 114 and the air outlet 116, ensuring that the return air and the air outlet of the air conditioner do not interfere with each other, and realizing orderly return air and orderly air outlet of the air conditioner.

[0113] On the basis of the first to seventh embodiments, further, as Figure 1 As shown, the air conditioner is a ceiling unit and is located on the ceiling, above the user, during daily use.

[0114] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown in the figure, the first specific embodiment of the present invention provides an air conditioner, which includes: a housing 102, a heat exchanger 110, a fan 112, an air return opening 114, and an air outlet 116. The housing 102 includes a housing body 104 and a shielding member 106 that are connected to each other. An internal fan chamber 108 is provided in the housing body 104, and the fan 112 is disposed in the fan chamber 108. The shielding member 106 is located at the bottom of the fan chamber 108 to shield the bottom of the housing body 104 and the fan 112. The heat exchanger 110 is disposed in the housing body 104 and can exchange heat with the air flow during the operation of the air conditioner to achieve the cooling and heating effects of the air conditioner. In addition, the air return opening 114 opens towards the side of the housing body 104. After the air conditioner is installed, when the user observes the air conditioner from the bottom of the air conditioner, there will be no large-sized air return opening 114, which greatly improves the aesthetic degree of the air conditioner.

[0115] And, as Figure 1 and Figure 2 shown, the shielding member 106 is located at the bottom of the fan chamber 108 and can be used to shield the fan chamber 108 and the communication port provided on the fan chamber 108. At the same time, other functional components can be provided on the shielding member 106, or the wall surface of the shielding member 106 can be beautified, further improving the aesthetic degree of the entire bottom of the air conditioner. The shielding member 106 can reduce the noise transmission during the operation of the air conditioner to a certain extent, and thus play a role in noise reduction to a certain extent, improving the comfort of the air conditioner during use.

[0116] In this embodiment, further, as Figure 1 and Figure 2 shown, the shielding member 106 includes a shielding plate, the shielding plate is connected to the housing body 104 and is located at the bottom of the fan chamber 108. In addition, the shielding plate is fixedly connected to the housing body 104. In this way, the structure of the shielding plate and the entire housing 102 can be effectively simplified.

[0117] In this embodiment, further, as Figure 1 and Figure 3 shown, there is an air return channel 120 between the bottom plate 130 of the housing body 104 and the shielding member 106, and an air flow port 122 is provided on the bottom plate 130 of the housing body 104. During the operation of the air conditioner, the external air flow can first enter the air return channel 120 through the air return opening 114, and the air flow in the air return channel 120 can enter the interior of the fan chamber 108 through the air flow port 122. The air flow in the fan chamber 108 is pressurized by the fan 112 and then flows out from the air outlet 116 to ensure the air supply of the air conditioner.

[0118] In this embodiment, further, as Figure 1 and Figure 3As shown, an air outlet passage 124 is provided on the housing body 104. The blower chamber 108 is communicated with the air outlet 116 through the air outlet passage 124, so as to ensure that the air flow in the blower chamber 108 passes through the air outlet passage 124 and is discharged from the air outlet 116. In addition, the number of the air outlet passages 124 is multiple, and the multiple air outlet passages 124 are circumferentially distributed along the housing body 104. In addition, the number of the air return openings 114 is multiple, and the multiple air return openings 114 are circumferentially distributed along the housing body 104. In addition, along the circumference of the housing body 104, the multiple air return openings 114 and the multiple air outlet passages 124 are alternately distributed. In addition, the air outlet 116 includes an annular air outlet, and the multiple air outlet passages 124 are communicated with the annular air outlet, and can ensure that the multiple air outlet passages 124 are uniformly communicated along the circumference of the annular air outlet. In addition, the air return opening 114 is provided on the side plate 132 of the housing body 104, and the air return opening 114 is opened towards the side of the housing body 104.

[0119] In this embodiment, further, as Figure 1 shown, the air outlet 116 includes a first sub-air outlet 126 and a second sub-air outlet 128. Among them, the first sub-air outlet 126 is provided on the housing body 104 and is opened towards the side of the housing body 104, and the second sub-air outlet 128 is provided on the housing body 104 and is opened towards the bottom of the housing body 104. In addition, the air conditioner further includes a conduction component, which is provided on the housing body 104 and can open or close the first sub-air outlet 126 and open or close the second sub-air outlet 128 during the operation of the air conditioner, so that the air conditioner blows air from the first sub-air outlet 126 or the second sub-air outlet 128. As Figure 5 、 ​ 、 ​ and ​ shown, when the air conditioner operates in the cooling mode, the conduction component controls the first sub-air outlet 126 to be in an open state and controls the second sub-air outlet 128 to be in a closed state. As ​ 、 ​ 、 ​ and ​ shown, when the air conditioner operates in the heating mode, the conduction component controls the second sub-air outlet 128 to be in an open state and controls the first sub-air outlet 126 to be in a closed state.

[0120] In this embodiment, further, as ​As shown, the bottom plate 130 of the housing body 104 is provided with an extension edge 134, and at least a part of the extension edge 134 extends towards the peripheral side of the housing body 104. The peripheral edge of the extension edge 134 is located at the bottom of the side plate 132 of the housing body 104; the first sub-air outlet 126 is located on the side plate 132 of the housing body 104, or the first sub-air outlet 126 is located between the side plate 132 and the extension edge 134 of the housing body 104. The second sub-air outlet 128 is located on the extension edge 134 to ensure that the second sub-air outlet 128 blows air towards the bottom of the housing body 104.

[0121] In this embodiment, further, as ​ shown, the conduction component includes a switch component 136 and an elastic conduction member 138. Among them, the switch component 136 is disposed at the first sub-air outlet 126 in a liftable manner and can be used to open or close the first sub-air outlet 126; the elastic conduction member 138 is disposed at the second sub-air outlet 128, and the elastic conduction member 138 is a normally closed element. When the switch component 136 closes the first sub-air outlet 126, the elastic conduction member 138 will open the second sub-air outlet 128. As ​ 、 ​ 、 ​ and ​ shown, when the air conditioner operates in the cooling mode, the switch component 136 opens the first sub-air outlet 126, and the elastic conduction member 138 closes the second sub-air outlet 128. As ​ 、 ​ 、 ​ and ​ shown, when the air conditioner operates in the heating mode, the switch component 136 closes the first sub-air outlet 126, and the air flow continuously accumulates in the air duct in the blower cavity 108, so that the air pressure in the blower cavity 108 increases. The elastic conduction member 138 is driven by the air pressure difference to open the second sub-air outlet 128. In addition, as ​ 、 ​ 、 ​ and ​ shown, regardless of whether the air conditioner is in the cooling mode or the heating mode, when a wider air outlet angle of the air conditioner needs to be achieved, the switch component 136 controls the first sub-air outlet 126 to be in a semi-open and semi-closed state. At this time, the external air flow enters the blower cavity 108 from the air return port 114, and after heat exchange, a part of it is discharged from the first sub-air outlet 126, and the other part in the blower cavity 108 will cause the air pressure in the blower cavity 108 to increase, so that the elastic conduction member 138 is driven by the air pressure difference to open the second sub-air outlet 128, making the second sub-air outlet 128 in a semi-open and semi-closed state, and further enabling the other part of the air flow to be discharged through the second sub-air outlet 128. At this time, the air conditioner can blow air towards the side and towards the bottom, achieving a wider air outlet effect.

[0122] In this embodiment, further, as ​ , ​ , ​ and ​ show, the switch assembly 136 includes a baffle 140 and a driving member 142. Among them, the driving member 142 is arranged on the housing body 104, and the baffle 140 is arranged at the first sub-air outlet 126 in a liftable manner; the driving member 142 is connected to the baffle 140 and can be used to drive the baffle 140 to lift, so as to open or close the first sub-air outlet 126.

[0123] In this embodiment, further, as ​ shows, the first sub-air outlet 126 is an annular air outlet, and the second sub-air outlet 128 is an annular air outlet. As ​ shows, the heat exchanger 110 is an annular heat exchanger 110, and the annular heat exchanger 110 is arranged on the circumferential side of the blower 112 to ensure that the distances from the blower 112 to the annular heat exchanger 110 are equal; as ​ shows, the housing 102 is an annular housing 102, and the annular housing 102 is matched with the annular heat exchanger 110 and the annular air outlet; as ​ shows, the blower 112 is a centrifugal blower 112, the annular heat exchanger 110 is arranged on the radial circumferential side of the centrifugal blower 112, and the air return opening 114 is arranged at the bottom of the centrifugal blower 112 in the axial direction.

[0124] In addition, in another embodiment, as ​ shows, the second sub-air outlet 128 can also be set as an arc-shaped air outlet 116, and a plurality of arc-shaped air outlets 116 are distributed along the circumferential direction of the housing body 104.

[0125] In this embodiment, further, as ​ shows, an installation position 144 is arranged on the shielding member 106. Among them, the installation position 144 can be used to install functional components to realize the multi-functions of the air conditioner. Specifically, the functional components include but are not limited to lighting lamps, etc. A wind guiding member 146 is arranged on the side plate 132 of the housing body 104, and the wind guiding member 146 is located between the air return opening 114 and the air outlet 116.

[0126] In a specific embodiment, the current large-scale air conditioner indoor units on the market mainly include duct machines and ceiling machines. Among them, the ceiling machine has a simple structure and its appearance has not been changed for a long time. The main components include a blower, a heat exchanger, an air outlet duct and an air return duct. The ceiling machine mainly takes the form of air outlet around the perimeter and air return at the center of the bottom surface. The blower sucks the indoor air from the air return duct, flows through the heat exchanger, and then sends it out through the air outlet duct. Its function is to heat or cool the indoor air to achieve the effect of adjusting the indoor temperature.

[0127] In the related art, a wind deflector is provided at the air outlet of an air conditioner. The wind deflector is arranged in a square shape and can adjust the air outlet angle; indoor air flow enters the fan from the return air outlet; generally, a centrifugal fan is used for the fan, and the air flow entering the fan axially flows out radially; the heat exchanger is arranged in a square shape and can heat or cool the air.

[0128] In particular, the fan has a cylindrical structure. Considering the heat exchange uniformity and the air outlet comfort, the square heat exchanger and the square air outlet arrangement are not the best choices. The distances from the outer edge of the fan to the heat exchanger are different. Therefore, the directions and speeds of the air blown from different positions of the fan when entering the square heat exchanger are not consistent. As a result, the heat exchange uniformity of the square heat exchanger is poor.

[0129] In addition, the square air outlet has air outlets on four sides and no air outlets at the four corners. Therefore, it will cause the air outlet to not fully cover in the horizontal direction. And, in order to avoid backflow, the design of returning air at the center of the bottom surface of the air outlet on four sides makes the angle of the air outlet unable to be opened too large, resulting in the air supply range not being able to cover a large range of space at the bottom of the air conditioner.

[0130] In addition, although the annular air outlet matching the shape of the fan has better heat exchange uniformity and air outlet comfort, the special arc shape cannot be installed with a rotating shaft, which is not conducive to the adjustment of the air outlet angle, resulting in a problem of structural interference between the annular air outlet and the rotatable wind deflector.

[0131] Therefore, the present invention proposes an air conditioner, which has an annular heat exchanger 110 and an annular air outlet, so that the internal flow of the air conditioner has better heat exchange uniformity and the external flow of the air conditioner has a more comprehensive air supply range.

[0132] In addition, the air conditioner has a new air outlet mode, which can better meet the different needs in the cooling and heating scenarios. As ​ 、 ​ 、 ​ and ​ shown, specifically, when the air conditioner operates in the cooling mode, air blows out from the first sub-air outlet 126 with a side opening, and the cold air will not directly blow towards the user; as ​ 、 ​ 、 ​ and ​ shown, when the air conditioner operates in the heating mode, air blows out from the second sub-air outlet 128 with a bottom opening, and the warm air blows towards the ground so that the user's feet are not frozen.

[0133] In addition, as ​ 、 ​ 、 ​ and ​As shown, the air conditioner has a brand-new appearance surface. When observed from the bottom, the large-sized air return opening 114 of the relevant components cannot be seen, so that the shielding member 106 at the original position of the air return opening 114 can be used for decorating or installing functional components such as lighting lamps.

[0134] In addition, the shielding member 106 at the bottom of the air conditioner can, to a certain extent, reduce the noise propagation during the operation of the air conditioner, and thus play a role in noise reduction to a certain extent.

[0135] In a specific embodiment, such as ​ 、 ​ 、 ​ and ​ As shown, the whole air conditioner is circular. The blower 112 adopts a centrifugal blower 112, and the heat exchanger 110 adopts an annular heat exchanger 110. During the operation of the air conditioner, the air flow enters the blower cavity 108 from the air return opening 114 above the air guiding member 146, flows to the heat exchanger 110 after being pressurized by the blower 112, and is discharged from the air outlet 116 below the air guiding member 146 after heat exchange through the heat exchanger 110.

[0136] In a specific embodiment, such as ​ As shown, the air outlet 116 includes a first sub-air outlet 126 and a second sub-air outlet 128. The first sub-air outlet 126 opens towards the side of the air conditioner, and the second sub-air outlet 128 opens towards the bottom of the air conditioner. A switch assembly 136 is arranged at the position of the first sub-air outlet 126 to control the opening and closing of the first sub-air outlet 126 (realized by the driving member 142 driving the shielding member 106 to move up and down, and the transmission mode can be realized by gears and racks); an elastic conduction member 138 is arranged at the position of the second sub-air outlet 128 to control the opening and closing of the second sub-air outlet 128 (the elastic conduction member 138 has a check function, and the second sub-air outlet 128 will only be opened when the air pressure value at the first sub-air outlet reaches a certain value).

[0137] In a specific embodiment, such as ​ 、 ​ 、 ​ and ​ As shown, when the air conditioner operates in the cooling mode, the driving member 142 drives the shielding member 106 to the highest position. At this time, the first sub-air outlet 126 is in the open state, and the air pressure value at the first sub-air outlet cannot conduct the elastic conduction member 138, and the second sub-air outlet 128 is in the closed state. Therefore, the air flow inside the air conditioner is discharged from the first sub-air outlet 126 opening towards the side, and the cold air covers above the user and gently sinks through natural convection, and the cold air does not directly blow on people.

[0138] In a specific embodiment, such as ​ 、 ​ 、 ​ and​ As shown, when the air conditioner operates in the heating mode, the driving member 142 drives the shielding member 106 to the lowest position. At this time, the first sub-air outlet 126 is in the closed state, and the air pressure value at the second sub-air outlet conducts the elastic conduction member 138, and the second sub-air outlet 128 is in the open state. Therefore, the air flow inside the air conditioner is discharged from the second sub-air outlet 128 with an opening at the bottom, causing the warm air to flow obliquely downward and then gently rise through natural convection, so that the warm air blows to the ground to achieve the function of warming the feet.

[0139] In a specific embodiment, as ​ 、 ​ 、 ​ and ​ shown, when a wider air supply range is required (whether the air conditioner operates in the cooling mode or the heating mode), the driving member 142 drives the shielding member 106 to a suitable intermediate position, so that part of the air flow is discharged from the first sub-air outlet 126 with a side opening, and part of the air flow is discharged from the second sub-air outlet 128 with an opening at the bottom. In addition, when fluctuating air supply is required, the shielding member 106 can be made to fluctuate regularly in the vertical direction.

[0140] Therefore, as ​ 、 ​ 、 ​ and ​ shown, the air conditioner proposed by the present invention can achieve 360° blowing of cold air on the horizontal plane during cooling, making full use of the natural sinking of cold air, and the temperature on the horizontal plane at different heights in the room is uniform; it can achieve 180° full coverage of hot air on the vertical plane during heating, and there will be no large temperature difference below and around the air conditioner. The hot air blows downward, and then uses the natural floating of hot air to achieve better air circulation in a large space. In addition, when the air conditioner is in the cooling mode, the cold air blows out at 0° to 15° above, and will not blow directly on people. When the air conditioner is in the heating mode, the hot air flows out from the multiple arc-shaped second sub-air outlets 128 and is quickly mixed with the surrounding air. When it reaches the human body, the wind speed has dropped to about 0.3 m / s, and there will be no discomfort of blowing. Through simulation analysis, compared with the related technology, the temperature difference on the horizontal plane during cooling can be reduced by about 2°, and the temperature stratification phenomenon during heating is weakened.

[0141] In addition, the bottom of the structure of this solution is a closed plane, and other functional modules such as lighting, humidification, and audio modules can be installed through the shielding member 106. In addition, small-sized openings can also be provided on the shielding member 106 to increase the return air area of the air conditioner.
