Description

Technical Field

[0001] This disclosure relates to the field of electrical technology, and more specifically, to a mid-frame structure and an air conditioner. Background Technology

[0002] With the improvement of living standards, people's functional needs for air conditioners have gone beyond the traditional cooling and heating functions, and they have placed higher demands on the intelligence of air conditioners. To meet these demands, integrating more detection devices into air conditioners has become a trend. These integrated detection devices collect and monitor information about the surrounding environment, thereby providing data for the intelligent control of the air conditioner. Consequently, how to provide a good operating environment for these integrated detection devices has become a problem that urgently needs to be solved in this field. Utility Model Content

[0003] This disclosure provides a mid-frame structure and an air conditioner.

[0004] According to a first aspect of this disclosure, a mid-frame structure is provided, comprising:

[0005] A middle frame, wherein the middle frame is provided with a mounting part, the mounting part being used to mount the detection component;

[0006] A drainage component is disposed in the middle frame, and the drainage component is at least partially located above the mounting part. The drainage component is used to receive condensate and guide the condensate away from the mounting part.

[0007] The drainage component is higher than the detection component. The drainage component is used to guide the condensate generated by the air conditioning heat exchange, and plays a role in directly blocking and guiding the condensate to prevent it from flowing directly into the detection component.

[0008] In one exemplary embodiment of this disclosure, the drainage assembly includes at least one drainage member, which is inclined relative to the mounting portion in the vertical direction.

[0009] The drainage component is used to guide the condensate generated by the air conditioning heat exchange, so that the condensate located above the middle frame can flow down along the inclined drainage component, preventing the condensate from entering the detection component and ensuring the reliability of the detection component.

[0010] In one exemplary embodiment of this disclosure, the drainage component includes at least two drainage elements, which are connected to each other and arranged at an included angle.

[0011] The two drainage components are interconnected to form an integral structure, preventing condensate from entering the detection component through the gap between them. The connection point between the two drainage components can directly receive condensate, allowing it to flow to both sides, increasing the flow path of the condensate, reducing its flow time within the drainage assembly, and improving drainage efficiency.

[0012] In one exemplary embodiment of this disclosure, the connection position between two adjacent drain members is located above the end of the drain member that is away from the connection position and close to the mounting portion.

[0013] With this configuration, an inverted V-shaped structure is formed between the two drainage components, meaning the entire drainage assembly is higher in the middle and lower on both sides. The connection point between the two drainage components marks the starting point of the condensate flow within the drainage assembly, while the end of the drainage component furthest from the connection point marks the ending point. Under the influence of gravity, the condensate flows from the connection point away from it, thus guiding the flow direction of the condensate and ensuring that as much condensate as possible is guided to both sides of the mounting section through the two drainage components, preventing condensate from entering the interior of the detection component.

[0014] In one exemplary embodiment of this disclosure, at least one of the drainage elements has a notch at one end remote from the connection location;

[0015] Alternatively, at least one of the drainage components may have a first ventilation section at one end away from the connection position, and the first ventilation section may have ventilation holes.

[0016] When air enters through the air inlet in the middle frame, it can continue to flow through the gaps as it passes through the air diversion component, preventing backflow due to obstruction by the air diversion component and improving the airflow effect inside the air conditioner.

[0017] When air enters from the air inlet of the middle frame and passes through the air diversion component, it can continue to flow through the ventilation holes provided on the first ventilation section, avoiding backflow of air due to obstruction by the air diversion component, which helps to improve the airflow effect inside the air conditioner.

[0018] In one exemplary embodiment of this disclosure, the notch is located on the side facing the detection signal transmission and reception direction of the detection component.

[0019] When the detection component transmits and receives detection signals, the notch can, to some extent, avoid the detection signal, reducing the risk of blocking the detection signal and thus improving the detection accuracy of the detection component.

[0020] In one exemplary embodiment of this disclosure, the mounting portion includes a sidewall, the sidewall being provided with a lead wire through hole for passing through the lead wire of the detection component;

[0021] The middle frame structure also includes a flow guide, which is connected to the side wall and extends in a direction away from the mounting portion, and is located above the lead wire through hole.

[0022] The lead through-hole provides clearance for the leads of the detection component. After passing through the lead through-hole, the leads of the detection component can be electrically connected to other electrical components such as controllers and power supplies.

[0023] The flow guide can receive condensate that flows through the draining component or flows along the side wall of the mounting part to the flow guide. The condensate can continue to flow through the flow guide, preventing condensate from entering the internal circuit of the detection component through the lead wire through hole and causing a short circuit, thus ensuring the reliability of the detection component.

[0024] In one exemplary embodiment of this disclosure, the connection between the flow guide and the sidewall is located above the end of the flow guide away from the connection.

[0025] That is, the connection between the guide member and the sidewall is higher than the end of the guide member away from the connection. The guide member and the sidewall are set at an obtuse angle, or the guide member is inclined downward relative to the sidewall. The connection between the guide member and the sidewall is the starting position of the condensate flow in the guide member, and the end of the guide member away from the connection is the ending position of the condensate flow in the guide member. Under the action of gravity, the condensate can flow from the connection between the guide member and the sidewall in a direction away from the connection. The guide member plays the role of guiding the condensate and planning the direction of the condensate flow, ensuring that as much condensate as possible flows along the guide member in a direction away from the lead wire through hole, and preventing condensate from entering the interior of the detection component through the lead wire or lead wire through hole.

[0026] In one exemplary embodiment of this disclosure, the guide extends from the mounting portion along the side away from the detection signal transmission and reception direction of the detection component.

[0027] That is, the first ventilation section can be used as an extension of one of the drainage components, and the guide component can be used as an extension of the other drainage component, so that after the condensate is drained by the two drainage components, it can be drained on both sides through the first ventilation section and the guide component, thus extending the drainage path and further improving the drainage effect.

[0028] In one exemplary embodiment of this disclosure, the end of the guide member away from the mounting portion is provided with an opening; or, the end of the guide member away from the mounting portion is provided with a second ventilation portion, and the second ventilation portion is provided with a ventilation hole.

[0029] Air entering through the air inlet in the middle frame can continue to flow through the openings as it passes through the air guide, preventing backflow due to obstruction by the air guide and improving the airflow efficiency inside the air conditioner.

[0030] Air entering through the air inlet in the middle frame can continue to flow through the ventilation holes on the second ventilation section as it passes through the air guide, thus preventing backflow due to obstruction by the air guide and improving the airflow effect inside the air conditioner.

[0031] In one exemplary embodiment of this disclosure, the detection component is a radar detection component.

[0032] Target detection, distance measurement, speed measurement, and angle measurement are performed using radar waves. The detection component is fixed to the middle frame via a mounting part and is used to detect objects or human activity in the environment surrounding the air conditioner to achieve intelligent control.

[0033] According to a second aspect of this disclosure, an air conditioner is provided, including the aforementioned mid-frame structure.

[0034] The mid-frame structure and air conditioner provided in this embodiment have a drainage component that is at least partially located above the mounting part. The drainage component is higher than the detection component and can guide the condensate generated by the air conditioner's heat exchange, directly blocking and guiding the condensate. After receiving the condensate located above the mid-frame, the drainage component guides the condensate to flow away from the mounting part, preventing it from flowing directly into the detection component and ensuring the reliability of the detection component.

[0059] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0060] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first” and “second” are used only as markers and are not a limitation on the number of objects.

[0061] This embodiment provides a mid-frame structure, such as Figures 1-3 As shown, the middle frame structure includes a middle frame 1 and a drainage component 2. The middle frame 1 is provided with a mounting part 10 for mounting the detection component 100. The drainage component 2 is disposed on the middle frame 1, and at least partially located above the mounting part 10. The drainage component 2 is used to collect condensate and guide the condensate away from the mounting part 10.

[0062] For example, the middle frame 1 resembles a cuboid structure, with a neat and aesthetically pleasing appearance. The middle frame 1 is a frame structure that provides installation positions for other components of the air conditioner and offers some support. The middle frame 1 has a first surface, which is a horizontal plane. A first direction is perpendicular to the horizontal plane, specifically the height direction of the middle frame 1, denoted by D1. A second direction and a third direction are two mutually perpendicular directions within the horizontal plane. The second direction is specifically the length direction of the middle frame 1, parallel to its long side, denoted by D2. The third direction is specifically the width direction of the middle frame 1, parallel to its short side, denoted by D3. The first, second, and third directions are mutually perpendicular to each other. These directions only represent spatial directions and have no substantial meaning.

[0063] For example, the middle frame 1 is provided with a mounting part 10 for mounting the detection component 100. Specifically, a slot is provided on the middle frame 1 for mounting the mounting part 10, which is simple in process and has a relatively low production cost. Alternatively, the mounting part 10 can be directly provided in the slot on the middle frame 1, that is, the slot for mounting the detection component 100 is directly machined on the middle frame 1. Specifically, the mounting part 10 can be provided in a mounting groove on the middle frame 1, or it can be provided in a mounting hole on the middle frame 1.

[0064] For example, the detection component 100 may specifically be a radar detection component, such as a signal detection device, which uses radar waves for target detection, distance measurement, speed measurement, and angle measurement. The detection component 100 is fixed to the middle frame 1 via the mounting part 10 and is used to detect objects or human activities in the environment surrounding the air conditioner to achieve intelligent control. For example, the detection component 100 can detect the presence of a person; specifically, by detecting minute movements such as breathing and slight movements, it can determine whether there is a person in the room, thereby achieving intelligent control of the air conditioner's on / off state or temperature adjustment. The detection component 100 can also analyze the movement trajectory of a person to determine their position and activity status, thereby achieving automatic adjustment of the air conditioner's airflow direction to avoid direct airflow onto the person. The detection component 100 can also perform environmental monitoring; specifically, it can detect the movement of objects in the room, and in conjunction with other devices such as temperature sensors, achieve more precise environmental control.

[0065] For example, the drainage component 2 is disposed on the middle frame 1. The middle frame 1 provides an installation position for the drainage component 2 and provides a certain support force. The drainage component 2 also strengthens the structural strength of the middle frame 1 to a certain extent. The drainage component 2 is at least partially located above the mounting part 10. For example, the drainage component 2 is located above the mounting part 10 along the first direction, that is, the drainage component 2 is higher than the detection component 100. The drainage component 2 is used to guide the condensate generated by the air conditioning heat exchange, and plays a role in directly blocking and guiding the condensate. After receiving the condensate located above the middle frame 1, the drainage component 2 guides the condensate to flow away from the mounting part 10, preventing the condensate from flowing directly into the interior of the detection component 100, and ensuring the reliability of the detection component 100.

[0066] like Figure 4 As shown, the detection component 100 includes a housing 110 and a signal element 120. The signal element 120 is disposed within the housing 110 and is inclined relative to the housing 110. The signal element 120 is used to transmit and receive detection signals. For example, the detection component 100 transmits radar waves of a specific frequency through the signal element 120. When the transmitted detection signal encounters a target object, a reflected signal is generated. The signal element 120 captures these radar waves and receives the reflected signals. The characteristics of the detection signal are used to obtain relevant information about the target object, such as frequency changes, phase changes, and signal strength, thereby calculating information such as the target object's distance, speed, and angle.

[0067] In this embodiment, the mounting part 10 may or may not have the detection component 100 installed, or the detection component 100 may be installed on the mounting part 10. For example, there may be multiple mounting parts 10 and multiple detection components 100, with the multiple detection components 100 correspondingly installed within multiple mounting parts 10. This embodiment uses two mounting parts 10 and two detection components 100 as an example, with two detection components 100 correspondingly installed within two mounting parts 10.

[0068] like Figure 5 As shown, the mounting part 10 includes a fixing part 101, which can be optionally provided in a slot on the middle frame 1. The fixing part 101 has a rectangular parallelepiped-like shape, and its shape is adapted to the external shape contour of the detection component 100.

[0069] like Figures 6-7As shown, the mounting part 10 may further include a fixing part 101 and an anti-interference part 102. The fixing part 101 is disposed on the middle frame 1, and the outer shell 110 of the detection component 100 is disposed on the fixing part 101. The fixing part 101 is used to mount and fix the detection component 100. The fixing part 101 and the anti-interference part 102 are connected, and the anti-interference part 102 is used to avoid detection signals transmitted and received by the detection component 100. It can be understood that the fixing part 101 and the anti-interference part 102 may specifically be two parts of a large slot; or, the slot corresponding to the fixing part 101 and the slot corresponding to the anti-interference part 102 are interconnected to form a complete slot.

[0070] Since the signal element 120 of the detection component 100 is inclined relative to the housing 110, the angle between the detection signal transmitted and received by the signal element 120 and the fixing part 101 is an acute angle. The fixing part 101 and the anti-interference part 102 are connected, and the anti-interference part 102 will not block the detection signal, thus avoiding interference and obstruction of the detection signal.

[0071] Specifically, the thickness of the anti-interference part 102 along the third direction is less than the thickness of the fixing part 101 along the third direction.

[0072] With this configuration, the anti-interference part 102 is thinned relative to the fixed part 101, so that the fixed part 101 and the anti-interference part 102 are not flush, but rather a clearance gap is formed between the fixed part 101 and the anti-interference part 102 to increase the clearance space and achieve the purpose of avoiding detection signals.

[0073] In one exemplary embodiment, such as Figures 8-10 As shown, the projections of the drainage component 2 onto the reference plane and the mounting portion 10 onto the reference plane at least partially overlap, where the reference plane is the plane containing the second and third directions. With this configuration, the drainage component 2 can at least partially cover the mounting portion 10, reducing the risk of condensate entering the mounting portion 10 under the guiding effect of the drainage component 2. For example, the projection of the mounting portion 10 onto the reference plane is located inside the projection of the drainage component 2 onto the reference plane, that is, the drainage component 2 is located directly above the mounting portion 10. The coverage area of ​​the drainage component 2 is relatively large, allowing it to completely cover the mounting portion 10 and preventing condensate from entering the interior of the detection component 100.

[0074] like Figures 11-12 As shown, the drainage assembly 2 includes at least one drainage element 21. The drainage element 21 is inclined relative to the mounting part 10 in the vertical direction. The drainage element 21 is used to guide the condensate generated by the air conditioning heat exchange, so that the condensate located above the middle frame 1 can flow down from top to bottom along the inclined drainage element 21, avoiding the condensate from entering the detection component 100 and ensuring the reliability of the detection component 100.

[0075] Specifically, the drainage component 2 includes at least two drainage elements 21, which are connected to each other and arranged at an angle.

[0076] The connection position 20 between the two drainage components 21 is correspondingly set to the mounting part 10. The two drainage components 21 are connected to form an integral structure, preventing condensate from entering the detection component 100 through the gap between the two drainage components 21. After the connection position 20 between the two drainage components 21 can directly receive condensate, the condensate can be diverted to both sides through the two drainage components 21, increasing the flow path of condensate drainage, reducing the flow time of condensate in the drainage assembly 2, and improving the drainage efficiency of condensate.

[0077] Specifically, the connection position 20 between two adjacent drainage members 21 is located above the end of the drainage member 21 that is away from the connection position 20 and close to the mounting portion 10. That is, the connection position 20 between the two drainage members 21 is higher than the end of the drainage member 21 that is away from the connection position 20, or the connection position 20 between the two drainage members 21 is the highest position of the drainage member 21.

[0078] With this configuration, an inverted V-shaped structure is formed between the two drainage elements 21, meaning the entire drainage assembly 2 is high in the middle and low on both sides. The connection point 20 between the two drainage elements 21 is the starting point for the flow of condensate in the drainage assembly 2, and the end of the drainage element 21 away from the connection point 20 is the ending point for the flow of condensate in the drainage assembly 2. Under the action of gravity, the condensate can flow from the connection point 20 between the two drainage elements 21 in a direction away from the connection point 20, thereby planning the flow direction of the condensate and ensuring that as much condensate as possible can be guided to both sides of the mounting part 10 through the two drainage elements 21, preventing condensate from entering the interior of the detection component 100.

[0079] It is understood that in some other embodiments, the connection position 20 between the two draining elements 21 is lower than the end of the draining element 21 away from the connection position 20. In this case, the entire draining assembly 2 has a structure that is low in the middle and high on both sides, and a V-shaped water collection tank is formed between the two draining elements 21. Under the action of gravity, the condensate flows along the inclined draining elements 21 and collects at the connection position 20 between the two draining elements 21. The condensate can be temporarily stored in the water collection tank and will not directly enter the interior of the detection component 100, which can also play a role in blocking the condensate to a certain extent.

[0080] For example, the two drainage members 21 may have the same or different lengths along the second direction. Specifically, the two drainage members 21 may have the same length and may be symmetrical about the left and right relative to the mounting portion 10 and along the first direction; the two drainage members 21 may also have different lengths and may not be symmetrical about the mounting portion 10.

[0081] Specifically, such as Figures 11-12 As shown, at least one draining element 21 has a notch 212 at the end away from the connection position 20.

[0082] For example, the size of the air intake 21 is reduced to form a notch 212, or a portion of the air intake 21 is heightened. When air enters from the air inlet of the middle frame 1, it can continue to flow through the notch 212 when passing through the air intake assembly 2, avoiding backflow of air due to obstruction by the air intake assembly 2, which helps to improve the airflow effect inside the air conditioner.

[0083] In one exemplary embodiment, such as Figure 13 As shown, at least one drain member 21 has a first ventilation section 211 at the end away from the connection position 20.

[0084] The first ventilation section 211 provides airflow space for the air entering the middle frame 1, preventing the airflow guide 21 from interfering with the airflow and affecting the air intake volume of the air conditioner, ensuring the smooth flow of airflow within the middle frame 1, thereby ensuring the final air output effect of the air conditioner and improving the air output volume. Since the connection position 20 between the two airflow guides 21 corresponds to the detection component 100, and the connection position 20 is the starting position for condensate to flow into the airflow guide 21, and the end of the airflow guide 21 away from the connection position 20 is the ending position for the condensate to flow in the airflow guide 21, by setting the first ventilation section 211 at the end of the airflow guide 21 away from the connection position 20, that is, the first ventilation section 211 can be located at the edge position on both sides of the airflow guide assembly 2, and the connection position 20 is close to the ending position of the condensate flow, the first ventilation section 211 will hardly affect the condensate drainage effect, so that the airflow guide 21 can simultaneously take into account the dual effects of drainage and ventilation, and has strong functionality.

[0085] like Figure 13 As shown, the first ventilation section 211 is provided with ventilation holes 213. When the air entering from the air inlet of the middle frame 1 passes through the air diversion component 2, it can continue to flow through the ventilation holes 213, avoiding the backflow of air caused by the air diversion component 2 blocking it, which is conducive to improving the airflow effect inside the air conditioner.

[0086] It is understandable that the air intake component 21 may also have a notch 212 and the first ventilation part 211 may have a ventilation hole 213, so that when the air entering from the air inlet of the middle frame 1 passes through the air intake component 2, part of the air can flow through the notch 212 and the other part of the air can flow through the ventilation hole 213, which can disperse the air, increase the air flow path, and further improve the smoothness of air flow.

[0087] The notch 212 is located on the side of the detection signal transmission and reception direction of the detection component 100.

[0088] With this configuration, when the detection component 100 transmits and receives detection signals, the notch 212 can avoid the detection signal to a certain extent, reducing the risk of blocking the detection signal and thus improving the detection accuracy of the detection component 100.

[0089] The first ventilation section 211 can be connected to the flow guide 21 by welding or bolting, or the first ventilation section 211 and the flow guide 21 can be integrally formed, saving the parts assembly process and reducing production costs.

[0090] It is understood that the entire drainage assembly 2 can be divided into a left part and a right part with the connection position 20 as the boundary. The length of the left part is greater than that of the right part. The left part can cover at least part of the fixing part 101 and the anti-interference part 102, so that the first ventilation part 211 can drain the condensate to a certain extent, and prevent the condensate from flowing into the fixing part 101 after entering the anti-interference part 102, which would cause the detection component 100 located in the fixing part 101 to be corroded by the condensate.

[0091] In one exemplary embodiment, such as Figures 12-14 As shown, the mounting part 10 includes a sidewall 103. Specifically, the sidewall 103 can be optionally disposed on the wall of the slot corresponding to the slot in the middle frame 1. For example, if the depth of the slot along a third direction is greater than the thickness of the middle frame 1 along a third direction, the sidewall 103 extends along the third direction and away from the middle frame 1, so that at least a portion of the sidewall 103 protrudes from the middle frame 1. In this case, the contact surface between the detection component 100 and the slot is relatively large, resulting in a better fixation effect for the detection component 100. The sidewall 103 can specifically be an annular sidewall, and the space enclosed by the annular sidewall is the slot, used to install the detection component 100. If the depth of the slot along a third direction is equal to the thickness of the middle frame 1 along a third direction, the sidewall 103 can also be disposed around the slot or along the edge of the slot, and the sidewall 103 protrudes from the middle frame 1. In this case, the slot wall acts as a guide or limiting element, facilitating the installation of the detection component 100 within the slot.

[0092] In an exemplary embodiment, the sidewall 103 of the mounting part 10 is provided with a lead wire through hole 1031, and the detection component 100 is provided with a lead wire terminal 130. The lead wire terminal 130 is connected to the lead wire of the detection component 100. The lead wire through hole 1031 provides clearance space for the lead wire of the detection component 100. After the lead wire of the detection component 100 passes through the lead wire through hole 1031, it can be electrically connected to other electrical components such as controllers and power supplies.

[0093] In one exemplary embodiment, such as Figures 12-14As shown, the middle frame structure also includes a flow guide 3, which is connected to the side wall 103 and extends in a direction away from the mounting portion 10. The flow guide 3 is located above the lead wire through hole 1031. Exemplarily, the flow guide 3 is located above the lead wire through hole 1031 in a first direction. After the lead wire of the detection component 100 passes through the lead wire through hole 1031, it forms a backflow bay when passing through the flow guide 3.

[0094] With this configuration, the guide member 3 can receive the condensate water that flows through the guide member 21, or the condensate water that flows along the side wall 103 of the mounting part 10 to the guide member 3. The condensate water can continue to flow through the guide member 3, preventing the condensate water from entering the internal circuit of the detection component 100 through the lead wire through hole 1031 and causing a short circuit, thus ensuring the reliability of the detection component 100.

[0095] For example, the guide member 3 extends from the mounting portion 10 along the side away from the detection signal transmission and reception direction of the detection component 100. Specifically, the first ventilation portion 211 and the guide member 3 are located on both sides of the fixing portion 101 of the mounting portion 10 along the second direction, and the first ventilation portion 211 is located on the side facing the detection signal transmission and reception direction of the detection component 100. That is, the first ventilation portion 211 can be used as an extension of one of the guide members 21, and the guide member 3 can be used as an extension of the other guide member 21, so that after the condensate is guided by the two guide members 21, it is guided by the first ventilation portion 211 and the guide member 3 on both sides, extending the guidance path and further improving the guidance effect.

[0096] The connection 30 between the guide member 3 and the side wall 103 is located above the end of the guide member 3 away from the connection 30, that is, the connection 30 between the guide member 3 and the side wall 103 is higher than the end of the guide member 3 away from the connection 30.

[0097] The guide member 3 and the side wall 103 are set at an obtuse angle, or the guide member 3 is inclined downward relative to the side wall 103. The connection 30 between the guide member 3 and the side wall 103 is the starting position of the flow of condensate in the guide member 3, and the end of the guide member 3 away from the connection 30 is the ending position of the flow of condensate in the guide member 3. Under the action of gravity, the condensate can flow from the connection 30 between the guide member 3 and the side wall 103 in a direction away from the connection 30. The guide member 3 plays the role of guiding the condensate and planning the flow direction of the condensate, ensuring that as much condensate as possible can flow along the guide member 3 in a direction away from the lead wire through hole 1031, and preventing the condensate from entering the interior of the detection component 100 through the lead wire or the lead wire through hole 1031.

[0098] In some exemplary embodiments, such as Figure 14As shown, the air guide 3 has an opening 32 at the end away from the mounting part 10. That is, the air guide 3 is partially heightened, so that the air entering from the air inlet of the middle frame 1 can continue to flow through the opening 32 when passing through the air guide 3, avoiding backflow of air due to obstruction by the air guide 3, which is beneficial to improving the airflow effect inside the air conditioner.

[0099] like Figure 15 As shown, a second ventilation section 31 is provided at the end of the guide member 3 away from the mounting section 10.

[0100] The second ventilation section 31 provides airflow space for the air entering the middle frame 1, preventing the air guide 3 from interfering with airflow and affecting the air intake volume of the air conditioner, ensuring smooth airflow within the middle frame 1, and thus ensuring the final air outlet effect of the air conditioner. Since the end of the air guide 3 away from the connection 30 is the termination point of the condensate flow, the second ventilation section 31 is set at the end of the air guide 3 away from the connection 30, that is, the second ventilation section 31 can be located at the edge of the air guide 3. The second ventilation section 31 has a relatively small impact on the condensate drainage effect, allowing the air guide 3 to simultaneously achieve the dual effects of drainage and ventilation, making it highly functional.

[0101] The second ventilation section 31 can be connected to the guide member 3 by welding or bolting; alternatively, the second ventilation section 31, the guide member 3, and the mounting section 10 can be at least partially integrally formed, saving the parts assembly process and reducing production costs.

[0102] Specifically, such as Figure 15 As shown, the second ventilation section 31 is provided with ventilation holes 33. When the air entering from the air inlet of the middle frame 1 passes through the guide 3, it can continue to flow through the ventilation holes 33, which avoids the backflow of air due to the obstruction of the guide 3 and helps to improve the airflow effect inside the air conditioner.

[0103] It is understandable that the guide 3 may also have an opening 32 and a ventilation hole 33 on the second ventilation section 31, so that when the air entering from the air inlet of the middle frame 1 passes through the guide 3, part of the air flows through the opening 32 and the other part flows through the ventilation hole 33, which plays a role in dispersing the air, increasing the air flow path, and further improving the smoothness of the air flow.

[0104] This embodiment also provides an air conditioner, such as Figure 16 As shown, the air conditioner includes the aforementioned mid-frame structure.

[0105] For example, the detection component 100 is installed on the mounting part 10 of the middle frame structure, that is, the detection component 100 can be fixedly installed on the mounting part 10 of the middle frame structure, which has good integrity and fixing effect; or, the detection component 100 can be detachably connected to the mounting part 10 of the middle frame structure, which facilitates the installation and removal of the detection component 100.

[0106] In this embodiment, the air conditioner has a flow-guiding component 2 disposed on the middle frame 1 and located above the mounting part 10 along the first direction. The flow-guiding component 2 is higher than the detection component 100. The flow-guiding component 2 is used to guide the condensate generated by the air conditioner heat exchange, and plays the role of directly blocking and guiding the condensate. After receiving the condensate located above the middle frame 1, the flow-guiding component 2 guides the condensate to flow away from the mounting part 10, so as to prevent the condensate from flowing directly into the interior of the detection component 100 and ensure the reliability of the detection component 100.
