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, demanding a higher level of intelligence. To meet these demands, integrating more detection devices into air conditioners has become a trend. These integrated devices collect and monitor information about the surrounding environment, providing data for intelligent air conditioner control. Consequently, ensuring the accuracy of the data provided by these integrated detection devices has become a pressing issue that needs to be addressed 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 first reinforcing structure is disposed on the middle frame and located on the side facing the detection signal transmission and reception direction of the detection component; a clearance portion is provided on the side of the first reinforcing structure away from the middle frame, the clearance portion being used to avoid the detection signals transmitted and received by the detection component.

[0007] The first reinforcing structure is located in the middle frame. The first reinforcing structure acts as a reinforcing rib to strengthen the structure of the middle frame, thereby improving the overall structural strength of the middle frame, without affecting the thickness of the whole machine.

[0008] A clearance portion is provided on the side of the first reinforcing structure away from the middle frame. The clearance portion is used to avoid the detection signals transmitted and received by the detection component, reduce the situation where the first reinforcing structure blocks the detection signal, increase the detection range of the detection signal, and thus improve the detection accuracy of the detection component.

[0009] In one exemplary embodiment of this disclosure, the clearance portion is a recess disposed on the upper surface of the first reinforcing structure, the length of the recess is equal to the length of the first reinforcing structure, and the width of the recess is equal to the width of the first reinforcing structure;

[0010] Alternatively, the avoidance part may be a notch.

[0011] In this way, the recess formed by the side of the first reinforcing structure away from the middle frame is the avoidance gap, which is equivalent to thinning the first reinforcing structure to increase the avoidance space, thereby achieving the purpose of avoiding the detection signal.

[0012] The inspection signal of the detection component can be transmitted and received through the gap, which provides clearance for the detection signal.

[0013] In one exemplary embodiment of this disclosure, it further includes:

[0014] A second reinforcing structure is disposed in the middle frame, and the second reinforcing structure is located on the side opposite to the detection signal transmission and reception direction of the detection component.

[0015] Specifically, the first and second reinforcing structures are located on opposite sides of the mounting portion. The first reinforcing structure is located on the side facing the detection signal transmission / reception direction of the detection component, while the second reinforcing structure is located on the side away from the detection signal transmission / reception direction of the detection component. When the detection component transmits or receives a detection signal, the clearance notch in the first reinforcing structure can avoid the detection signal. Since the second reinforcing structure is located away from the detection signal transmission / reception direction of the detection component, even if the second horizontal portion of the second reinforcing structure is higher along the height direction of the middle frame, and the second vertical portion is wider along the width direction of the middle frame, the second reinforcing structure will not interfere with the detection signal of the detection component.

[0016] By arranging a first reinforcing structure in the area of ​​the mid-frame that would interfere with the detection signal of the detection component, and setting a second reinforcing structure in the area of ​​the mid-frame that would not interfere with the detection signal of the detection component, the layout of the two reinforcing structures is reasonable. While ensuring the overall structure of the mid-frame, it will not obstruct the detection signal of the detection component.

[0017] In one exemplary embodiment of this disclosure, the middle frame includes an air outlet grille and a sidewall arranged at an angle;

[0018] The first reinforcing structure includes a first vertical part and a first horizontal part. The first horizontal part is disposed on the air outlet grille and extends along the width direction of the middle frame. The first vertical part is disposed on the side wall and connected to the first horizontal part.

[0019] The second reinforcing structure includes a second vertical part and a second horizontal part. The second horizontal part is disposed on the air outlet grille and extends along the width direction of the middle frame. The second vertical part is disposed on the side wall and connected to the second horizontal part.

[0020] Wherein, along the height direction of the middle frame, the height of the first horizontal part is less than the height of the second horizontal part;

[0021] The height direction and the width direction of the middle frame are perpendicular to each other.

[0022] The first horizontal section is positioned relatively low along the height of the middle frame, or its protrusion from the air outlet grille is also relatively low, reducing the likelihood of it obstructing the detection signal of the detection component. Simultaneously, the height of the clearance notch along the height of the middle frame can be increased to enlarge its size and range. This allows more detection signals close to the outlet grille to pass through the clearance notch, reducing the risk of the first horizontal section obstructing the detection signal and thus improving the detection accuracy of the detection component.

[0023] In one exemplary embodiment of this disclosure, the middle frame includes an air outlet grille and a sidewall arranged at an angle;

[0024] The first reinforcing structure includes a first vertical part, one end of which is connected to the air outlet grille and disposed on the side wall;

[0025] The second reinforcing structure includes a second vertical part and a second horizontal part. The second horizontal part is disposed on the air outlet grille and extends along the width direction of the middle frame. The second vertical part is disposed on the side wall and connected to the second horizontal part.

[0026] The first reinforcing structure is equivalent to having no first horizontal section, or the height of the first horizontal section along the height direction of the middle frame is reduced to zero, while the second horizontal section of the second reinforcing structure has at least a certain height along the height direction of the middle frame, thus preventing the first horizontal section of the first reinforcing structure from obstructing the detection signal of the detection component. Simultaneously, the height space of the clearance notch along the height direction of the middle frame can be increased, maximizing the size of the clearance notch along the height direction of the middle frame, further increasing the clearance space range of the clearance notch in the height direction of the middle frame. This allows the detection signal that fits against the exit grille to pass through the clearance notch, avoiding the risk of obstructing this part of the detection signal, thereby improving the detection accuracy of the detection component.

[0027] In one exemplary embodiment of this disclosure, the dimension of the first vertical portion along the width direction of the middle frame is smaller than the dimension of the second vertical portion along the width direction of the middle frame.

[0028] The first vertical section is positioned relatively low along the width of the middle frame, or the width of the first vertical section protruding from the sidewall is relatively small, reducing the obstruction of the detection signal by the detection component. Simultaneously, the space along the width of the clearance notch can be increased to enlarge the size of the clearance notch and increase its clearance range in the width direction of the middle frame. This allows more detection signals close to the sidewall to pass through the clearance notch, reducing the risk of the first vertical section obstructing the detection signal and thus improving the detection accuracy of the detection component.

[0029] In one exemplary embodiment of this disclosure, the middle frame structure includes at least two first reinforcing structures; the first reinforcing structures and the second reinforcing structures are arranged at intervals along the length direction of the middle frame.

[0030] Because the first reinforcing structure has an avoidance gap, the structural strength of the first reinforcing structure will be reduced to a certain extent. By arranging the first and second reinforcing structures at intervals along the length of the middle frame, the second reinforcing structure is used to strengthen the structural strength of the middle frame to make up for the insufficient strength of the first reinforcing structure and ensure the stability of the overall structure of the middle frame.

[0031] In one exemplary embodiment of this disclosure, the middle frame structure includes two mounting portions and two first reinforcing structures;

[0032] The second reinforcing structure is located between the two mounting portions; the two first reinforcing structures are located on the side of each mounting portion away from the second reinforcing structure.

[0033] For example, there are two mounting parts, which are used to mount two detection components. The second reinforcing structure is located between the two mounting parts to ensure the strength of the middle frame in the area between the two mounting parts. There are also two first reinforcing structures, which are located outside the two mounting parts and can respectively avoid the detection signals transmitted and received by the two detection components. At this time, the second reinforcing structure is also located between the two first reinforcing structures. The second reinforcing structure can simultaneously compensate for the insufficient strength of the two first reinforcing structures and avoid affecting the structural strength of the middle frame after the two first reinforcing structures are thinned.

[0034] In one exemplary embodiment of this disclosure, the first reinforcing structure includes:

[0035] At least two parallel, spaced-apart reinforcing members;

[0036] Multiple support members are spaced apart between two adjacent reinforcing members, and the multiple support members abut against the two adjacent reinforcing members respectively.

[0037] The first reinforcing structure is not a single reinforcing rib, but rather has multiple reinforcing members to increase the structural strength of the middle frame. At the same time, adjacent reinforcing members are connected by multiple supporting members, which act as intermediate connectors and further enhance the overall strength of the middle frame.

[0038] In one exemplary embodiment of this disclosure, the detection component is a radar detection component.

[0039] 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.

[0040] According to a second aspect of this disclosure, an air conditioner is provided, including the aforementioned mid-frame structure.

[0041] In one exemplary embodiment of this disclosure, the air conditioner includes a plurality of detection components, and the number of mounting portions is plurality of, with the plurality of detection components and the plurality of mounting portions being correspondingly arranged;

[0042] The detection signal transmission and reception directions of two adjacent detection components located on both sides of the first reinforcing structure are arranged facing each other.

[0043] The detection signal transmission and reception directions of two adjacent detection components are both set towards the first reinforcing structure. By utilizing the avoidance gap corresponding to the first reinforcing structure, the detection signals transmitted and received by the two detection components can be avoided at the same time, thereby improving the avoidance effect and reducing production costs.

[0044] The mid-frame structure and air conditioner provided in this embodiment have a first reinforcing structure disposed in the mid-frame. The first reinforcing structure acts as a reinforcing rib, improving the overall structural strength of the mid-frame. By arranging the first reinforcing structure in areas of the mid-frame that may interfere with the detection signal, the avoidance gap of the first reinforcing structure is used to avoid the detection signal transmitted or received by the detection component when the detection component transmits or receives the detection signal. This reduces the possibility of the first reinforcing structure obstructing the detection signal, increases the detection range of the detection signal, and thus improves the detection accuracy of the detection component.

[0066] 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.

[0067] 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.

[0068] This embodiment provides a mid-frame structure, such as Figures 1-2 As shown, the middle frame structure includes a middle frame 1 and a first reinforcing structure 2. The middle frame 1 is provided with a mounting part 10 for mounting the detection component 100. The first reinforcing structure 2 is disposed on the middle frame 1 and located on the side facing the detection signal transmission and reception direction of the detection component 100. A clearance part 20 is provided on the side of the first reinforcing structure 2 away from the middle frame 1 for avoiding the detection signals transmitted and received by the detection component 100.

[0069] For example, the middle frame 1 is a frame structure that provides installation positions for other components of the air conditioner and provides a certain degree of support. The middle frame 1 has a first surface, which is either horizontal or parallel to the horizontal plane. The height direction of the middle frame 1 is perpendicular to the horizontal plane and is identified by D1. The width direction and length direction of the middle frame 1 are two mutually perpendicular directions within the horizontal plane. The width direction of the middle frame 1 is parallel to its shorter side within the horizontal plane and is identified by D2. The length direction of the middle frame 1 is parallel to its longer side within the horizontal plane and is identified by D3. The height, width, and length directions of the middle frame 1 are mutually perpendicular and represent spatial directions only; they have no substantive meaning.

[0070] For example, the middle frame 1 is provided with a mounting portion 10 for mounting the detection component 100. Specifically, a slot is provided on the middle frame 1 for mounting the mounting portion 10, which is simple in process and has a relatively low production cost. Alternatively, the mounting portion 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. For example, the mounting portion 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.

[0071] For example, the detection component 100 may specifically be a radar detection component, such as a radar detection device, which uses radar waves to perform target detection, distance measurement, speed measurement, and angle measurement. The detection component 100 is fixed to the middle frame 1 by 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 minute movements such as human breathing and micro-movements to determine whether there is anyone in the room, thereby realizing intelligent control of the air conditioner's on / off state or temperature adjustment; the detection component 100 can also analyze the human body's movement trajectory to determine the human body's position and activity state, realizing automatic adjustment of the air conditioner's airflow direction to avoid direct airflow onto the human body; the detection component 100 can also perform environmental monitoring, specifically, detecting the movement of objects in the room, and combined with other devices such as temperature sensors, to achieve more precise environmental control.

[0072] During the manufacturing of the middle frame 1, due to mold factors, the middle frame 1 is generally a hollow structure. Although the structural strength is relatively poor, it has the advantage of being lightweight, which can meet the user's lightweight usage needs.

[0073] In the middle frame structure provided in this embodiment, the first reinforcing structure 2 is disposed on the middle frame 1. The first reinforcing structure 2 acts as a reinforcing rib to strengthen the structure of the middle frame 1, thereby improving the overall structural strength of the middle frame 1, without affecting the thickness of the whole machine.

[0074] For example, the first reinforcing structure 2 is disposed on the middle frame 1. The shape of the first reinforcing structure 2 can be selected from at least one of the following: a straight line structure, an L-shaped structure, a cross-shaped structure, a grid-shaped structure, a square-shaped structure, or other regular or irregular structures such as a flat plate. The first reinforcing structure 2 is located on at least one side of the mounting part 10 along the length direction of the middle frame 1, and the first reinforcing structure 2 can strengthen the structure of the area near the mounting part 10.

[0075] The first reinforcing structure 2 is located on the side facing the detection signal transmission and reception direction of the detection component 100. If the first reinforcing structure 2 protrudes significantly from the middle frame 1, it may obstruct the detection signals transmitted and received by the detection component 100, affecting the detection range and resulting in low detection accuracy. Therefore, by arranging the first reinforcing structure 2 in the area of ​​the middle frame 1 where interference with the detection signal is possible, the clearance notch 20 of the first reinforcing structure 2 is used to avoid obstructing the detection signals when the detection component 100 transmits and receives detection signals. This reduces the likelihood of the first reinforcing structure 2 obstructing the detection signal, increases the detection range, and thus improves the detection accuracy of the detection component 100.

[0076] Specifically, the clearance portion 20 is a recess provided on the upper surface of the first reinforcing structure 2. The length of the recess is equal to the length of the first reinforcing structure 2, and the width of the recess is equal to the width of the first reinforcing structure 2. For example, the upper surface of the first reinforcing structure 2 is the top surface of the first reinforcing structure 2 along the height direction of the middle frame 1. Along the length direction of the middle frame 1, the length of the recess is equal to the length of the first reinforcing structure 2, and along the width direction of the middle frame 1, the width direction of the recess is equal to the width of the first reinforcing structure 2.

[0077] In this way, the length of the recess is equal to the length of the portion of the first reinforcing structure 2 where the recess is provided, and the width of the recess is equal to the width of the portion of the first reinforcing structure 2 where the recess is provided. The recess formed by the side of the first reinforcing structure 2 away from the middle frame 1 is the avoidance gap 20, which is equivalent to thinning the first reinforcing structure 2 to increase the avoidance space, thereby achieving the purpose of avoiding the detection signal.

[0078] It is understood that the recess can also be a recess provided on the outer side of the first reinforcing structure 2. For example, the outer side of the first reinforcing structure 2 is the side of the first reinforcing structure 2 along the width direction of the middle frame 1 and away from the middle frame 1. The length of the recess is equal to the length of the first reinforcing structure 2, and the width of the recess is equal to the width of the first reinforcing structure 2.

[0079] Specifically, the clearance part 20 is a notch, which can be a groove or a through hole. The inspection signal of the detection component can be transmitted and received through the notch, and the notch provides clearance space for the detection signal.

[0080] For example, if the first reinforcing structure 2 is a plate-shaped structure before the clearance notch 20 is processed, a groove is opened on the top surface of the first reinforcing structure 2 along the height direction of the middle frame 1, and this groove is the clearance notch 20; or a groove is opened on the outer side of the first reinforcing structure 2 along the width direction of the middle frame 1 and away from the middle frame 1, and this groove is the clearance notch 20. The shape of the groove can be a rectangular groove, a trapezoidal groove, a dovetail groove, etc.; or the groove provided in the first reinforcing structure 2 can be a through groove structure. For example, the groove simultaneously penetrates the top surface of the first reinforcing structure 2 along the height direction of the middle frame 1 and the side surface along the width direction of the middle frame 1 and away from the middle frame 1 to form an open opening. This through groove structure is the clearance notch 20.

[0081] In some other embodiments, a through hole may be provided in the middle or other positions of the first reinforcing structure 2. This through hole is the clearance notch 20. The shape of the through hole includes, but is not limited to, regular or irregular shapes such as rectangle, circle, triangle, and ellipse. For example, the through hole may be a rectangular through hole. The shape of the first reinforcing structure 2 is similar to a U-shaped structure. The detection signal can be directly transmitted and received through the through hole, reducing the possibility of obstructing the detection signal.

[0082] like Figure 3 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 signal element 120 transmits a detection signal of a specific frequency, such as a radar wave. When the transmitted radar wave encounters a target object, it generates a reflected signal. The signal element 120 captures these radar waves and receives the reflected detection signal. It utilizes the characteristics of the detection signal 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.

[0083] The mounting part 10 can be equipped with a detection component 100. The number of mounting parts 10 can be one, with at least one first reinforcing structure 2 and one mounting part 10 correspondingly arranged; the number of mounting parts 10 can also be multiple, with multiple first reinforcing structures 2 and multiple mounting parts 10 correspondingly arranged. For example, two detection components 100 are correspondingly arranged in two mounting parts 10, and two mounting parts 10 are correspondingly arranged with two first reinforcing structures 2. The clearance notches 20 of the two first reinforcing structures 2 respectively avoid the detection signals transmitted and received by the two detection components 100.

[0084] For example, such as Figure 4As shown, the mounting part 10 includes a fixing part 101. The fixing part 101 can be optionally provided in a mounting hole or mounting groove on the middle frame 1. The shape of the fixing part 101 is similar to a cuboid structure, and the shape of the fixing part 101 is adapted to the external shape contour of the detection component 100.

[0085] For example, such as Figure 5 As 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 housing 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.

[0086] Since the signal element 120 of the detection component 100 is inclined relative to the housing 110, the angle between the signal element 120 transmitting and receiving detection signals 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 caused by the small angle between the detection signal and the fixing part 101.

[0087] Specifically, the thickness of the anti-interference part 102 along the length of the middle frame 1 is less than the thickness of the fixing part 101 along the length of the middle frame 1. With this arrangement, the anti-interference part 102 is thinned relative to the fixing part 101, so that the fixing part 101 and the anti-interference part 102 are not flush, but a gap is formed between the fixing part 101 and the anti-interference part 102 to increase the clearance space and achieve the purpose of avoiding detection signals.

[0088] In some exemplary embodiments, such as Figures 1-3 As shown, the middle frame structure also includes a second reinforcing structure 3, which is disposed on the middle frame 1.

[0089] For example, the number of second reinforcing structures 3 can be selected as one, and the second reinforcing structure 3 is located on the left or right side of the mounting part 10 along the length direction of the middle frame 1. By setting the second reinforcing structure 3 on the middle frame 1, the second reinforcing structure 3 acts as a reinforcing rib to strengthen the structure of the middle frame 1, thereby improving the overall structural strength of the middle frame 1, without affecting the thickness of the whole machine.

[0090] For example, the first reinforcing structure 2 and the second reinforcing structure 3 are arranged along the length direction of the middle frame 1. Specifically, the first reinforcing structure 2 and the second reinforcing structure 3 may also be located on both sides of the mounting portion 10 along the length direction of the middle frame 1, thereby increasing the structural reinforcement of the middle frame 1 and ensuring a certain degree of balance in the structural strength of both sides of the mounting portion 10. In some other embodiments, the first reinforcing structure 2 and the second reinforcing structure 3 may also be located on the same side of the mounting portion 10 along the length direction of the middle frame 1, thereby increasing the structural strength of one side of the mounting portion 10.

[0091] It is understandable that the first reinforcing structure 2 and the second reinforcing structure 3 can be independently set on the middle frame 1. For example, the first reinforcing structure 2 and the second reinforcing structure 3 can be connected to the middle frame 1 by welding, bolts, etc.; the first reinforcing structure 2, the second reinforcing structure 3 and the middle frame 1 can also be an integrally formed structure, reducing the parts assembly process and saving production costs.

[0092] Specifically, the second reinforcing structure 3 is located on the side opposite to the detection signal transmission and reception direction of the detection component 100. The first reinforcing structure 2 and the second reinforcing structure 3 are located on opposite sides of the mounting portion 10, i.e., the first reinforcing structure 2 is located on the side facing the detection signal transmission and reception direction of the detection component 100, and the second reinforcing structure 3 is located on the side opposite to the detection signal transmission and reception direction of the detection component 100.

[0093] When the detection component 100 transmits or receives detection signals, the clearance notch 20 of the first reinforcing structure 2 can avoid the detection signals. The second reinforcing structure 3 is located on the side opposite to the detection signal transmission / reception direction of the detection component 100. Even if the second horizontal portion 32 of the second reinforcing structure 3 is higher along the height direction of the middle frame 1 and the second vertical portion 31 is wider along the width direction of the middle frame 1, the second reinforcing structure 3 will not interfere with the detection signals of the detection component 100.

[0094] By arranging a first reinforcing structure 2 in the area of ​​the middle frame 1 that may interfere with the detection signal, and arranging a second reinforcing structure 3 in the area of ​​the middle frame 1 that will hardly interfere with the detection signal, the layout of the two reinforcing structures is reasonable. While ensuring the overall structure of the middle frame 1, it will not block the detection signals transmitted and received by the detection component 100.

[0095] In some exemplary embodiments, such as Figures 1-3 As shown, the middle frame structure includes at least two first reinforcing structures 2, and the two first reinforcing structures 2 and the second reinforcing structure 3 are arranged at intervals along the length direction of the middle frame 1.

[0096] Because the first reinforcing structure 2 has an avoidance gap 20, the structural strength of the first reinforcing structure 2 will be reduced to a certain extent. By arranging the first reinforcing structure 2 and the second reinforcing structure 3 alternately, the second reinforcing structure 3 is used to strengthen the structural strength of the middle frame 1 to make up for the insufficient strength of the first reinforcing structure 2 and ensure the overall structural stability of the middle frame 1.

[0097] Specifically, the middle frame structure includes two mounting parts 10 and two first reinforcing structures 2, with a second reinforcing structure 3 located between the two mounting parts 10, and the two first reinforcing structures 2 located on the side of the two mounting parts 10 away from the second reinforcing structure 3.

[0098] For example, two mounting portions 10 are used to mount two detection components 100 respectively, and the second reinforcing structure 3 is located between the two mounting portions 10 to ensure the strength of the middle frame 1 in the area between the two mounting portions 10. There are two first reinforcing structures 2, each located on the outside of the two mounting portions 10, and each first reinforcing structure 2 can avoid the detection signals transmitted and received by the two detection components 100. At this time, the second reinforcing structure 3 is also located between the two first reinforcing structures 2. Using one second reinforcing structure 3 can simultaneously compensate for the insufficient strength of the two first reinforcing structures 2, preventing the thinning of the two first reinforcing structures 2 from affecting the structural strength of the middle frame 1.

[0099] Among them, such as Figures 6-7 As shown, the projection of the first reinforcing structure 2 onto the reference plane is located inside the projection of the second reinforcing structure 3 onto the reference plane; wherein, the reference plane is the plane containing the height direction and the width direction of the middle frame 1, the height direction and the width direction of the middle frame 1 are perpendicular to each other, and the reference plane can also be referred to as the longitudinal cross-section of the middle frame 1.

[0100] With this configuration, the overall size of the first reinforcing structure 2 is reduced relative to the second reinforcing structure 3. The area where the overall size of the first reinforcing structure 2 is reduced relative to the second reinforcing structure 3 is the avoidance gap 20, which is used to avoid the detection signal of the detection component 100, reduce the risk of blocking the detection signal, and thus improve the detection accuracy of the detection component 100.

[0101] It is understood that in some other embodiments, during actual manufacturing, multiple second reinforcing structures 3 can be simultaneously manufactured on the middle frame 1, and then the surface of one of the second reinforcing structures 3 away from the middle frame 1 can be reduced to form a first reinforcing structure 2. Compared with manufacturing the first reinforcing structure 2 and the second reinforcing structure 3 separately, the production process is simplified and the production cost is reduced.

[0102] like Figures 6-7 As shown, the middle frame 1 includes a side wall 12. Exemplarily, the side wall 12 may be a rectangular frame structure. The side wall 12 extends approximately along the height direction of the middle frame 1. An air inlet is provided at the top of the side wall 12 along the height direction of the middle frame 1 for introducing air. The middle frame 1 also includes an air outlet grille 11, which is located at the bottom of the side wall 12 along the height direction of the middle frame 1. That is, the side wall 12 and the air outlet grille 11 are arranged at an angle. For example, the angle between the side wall 12 and the air outlet grille 11 may be an acute angle, a right angle, or an obtuse angle. After the air introduced from the air inlet enters the middle frame 1, the hot or cold air after heat exchange is discharged through the air outlet grille 11.

[0103] In some exemplary embodiments, such as Figure 6As shown, the first reinforcing structure 2 includes a first vertical portion 21 and a first horizontal portion 22. The first horizontal portion 22 is disposed on the air outlet grille 11 and extends along the width direction of the middle frame 1. The first vertical portion 21 is disposed on the side wall 12 of the middle frame 1 and connected to the first horizontal portion 22. The first vertical portion 21 can extend along the height direction of the middle frame 1; or the first vertical portion 21 can extend at an acute angle to the height direction of the middle frame 1. The first vertical portion 21 and the first horizontal portion 22 form an L-shaped structure, that is, the first reinforcing structure 2 is located between the side wall 12 of the middle frame 1 and the air outlet grille 11. While serving as an intermediate connection, it can also improve the structural strength of the connection area between the air outlet grille 11 and the side wall 12.

[0104] It is understandable that the area between the side of the first horizontal part 22 away from the air outlet grille 11 and the side of the first vertical part 21 away from the side wall 12 is the clearance gap 20.

[0105] like Figure 6 As shown, the second reinforcing structure 3 includes a second vertical portion 31 and a second horizontal portion 32. The second horizontal portion 32 is disposed on the air outlet grille 11 and extends along the width direction of the middle frame 1. The second vertical portion 31 is disposed on the side wall 12 of the middle frame 1 and is connected to the second horizontal portion 32. The second vertical portion 31 extends along the height direction of the middle frame 1, or it extends at an acute angle to the height direction of the middle frame 1. For example, the second vertical portion 31 and the second horizontal portion 32 form an L-shaped structure, that is, the second reinforcing structure 3 is located between the side wall 12 of the middle frame 1 and the air outlet grille 11. While serving as an intermediate connection, it can also improve the structural strength of the connection area between the air outlet grille 11 and the side wall 12.

[0106] Along the height direction of the middle frame 1, the height of the first horizontal part 22 is less than the height of the second horizontal part 32.

[0107] That is, the height position of the first horizontal part 22 along the height direction of the middle frame 1 is relatively low, or the height of the first horizontal part 22 protruding from the air outlet grille 11 is relatively low, reducing the possibility of the first horizontal part 22 obstructing the detection signal of the detection component 100. At the same time, the height space of the avoidance notch 20 along the height direction of the middle frame 1 can be increased to enlarge the size of the avoidance notch 20 and increase the avoidance space range of the avoidance notch 20 in the height direction of the middle frame 1, so that more detection signals that are close to the air outlet grille 11 can pass through the avoidance notch 20, reducing the risk of the first horizontal part 22 obstructing the detection signal, thereby improving the detection accuracy of the detection component 100.

[0108] In particular, along the width direction of the middle frame 1, the width of the first vertical part 21 is smaller than the width of the second vertical part 31.

[0109] That is, the first vertical portion 21 is positioned relatively low along the width direction of the middle frame 1, reducing the risk of the first vertical portion 21 obstructing the detection signal of the detection component 100. At the same time, the space of the clearance notch 20 along the width direction of the middle frame 1 can be increased to enlarge the size of the clearance notch 20 and increase the clearance space range of the clearance notch 20 in the width direction of the middle frame 1. This allows more detection signals that are close to the side wall 12 to pass through the clearance notch 20, reducing the risk of the first vertical portion 21 obstructing the detection signal, thereby improving the detection accuracy of the detection component 100.

[0110] In some exemplary embodiments, such as Figures 7-10 As shown, the first reinforcing structure 2 includes a first vertical part 21, which is disposed on the side wall 12 and connected to the air outlet grille 11.

[0111] For example, the first vertical portion 21 has a bottom surface along the height direction of the middle frame 1 and facing the air outlet grille 11, and the bottom surface of the first vertical portion 21 is connected to the air outlet grille 11; the first vertical portion 21 also has a side surface along the width direction of the middle frame 1 and facing the side wall 12, and the side surface of the first vertical portion 21 is connected to the side wall 12, and the area of ​​the bottom surface is much smaller than the area of ​​the side surface. At this time, the first reinforcing portion is similar to a rod-shaped structure, and the first reinforcing structure 2 is located between the side wall 12 of the middle frame 1 and the air outlet grille 11, which not only serves as an intermediate connection, but also improves the structural strength of the middle frame 1.

[0112] It is understandable that the area between the side of the first vertical part 21 away from the side wall 12 and the air outlet grille 11 is the clearance gap 20.

[0113] like Figure 7 As shown, the second reinforcing structure 3 includes a second vertical portion 31 and a second horizontal portion 32. The second horizontal portion 32 is disposed on the air outlet grille 11 and extends along the width direction of the middle frame 1. The second vertical portion 31 is connected to the side wall 12 of the middle frame 1 and to the second horizontal portion 32. The second vertical portion 31 extends along the height direction of the middle frame 1; or the second vertical portion 31 extends at an acute angle to the height direction of the middle frame 1. Exemplarily, the second vertical portion 31 and the second horizontal portion 32 form an L-shaped structure, that is, the second reinforcing structure 3 is located between the side wall 12 of the middle frame 1 and the air outlet grille 11, serving as an intermediate connection while also improving the structural strength of the middle frame 1.

[0114] With this configuration, the height of the first horizontal portion 22 along the height direction of the middle frame 1 is reduced to zero, or the first reinforcing structure 2 is essentially without the first horizontal portion 22, while the second horizontal portion 32 of the second reinforcing structure 3 has at least a certain height along the height direction of the middle frame 1, thus preventing the first horizontal portion 22 of the first reinforcing structure 2 from obstructing the detection signal of the detection component 100. Simultaneously, the height space of the clearance notch 20 along the height direction of the middle frame 1 can be increased, maximizing the size of the clearance notch 20 along the height direction of the middle frame 1. This further increases the clearance space range of the clearance notch 20 in the height direction of the middle frame 1, ensuring that detection signals that fit against the air outlet grille 11 can pass through the clearance notch 20, avoiding the risk of obstructing this portion of the detection signal, thereby improving the detection accuracy of the detection component 100.

[0115] In particular, along the width direction of the middle frame 1, the size of the first vertical part 21 is smaller than the size of the second vertical part 31.

[0116] That is, the position of the first vertical part 21 along the width direction of the middle frame 1 is relatively low, reducing the obstruction of the detection signal of the detection component 100 by the first vertical part 21. At the same time, the space of the avoidance notch 20 along the width direction of the middle frame 1 can be increased to increase the size of the avoidance notch 20 and increase the avoidance space range of the avoidance notch 20 in the width direction of the middle frame 1. This allows more detection signals that are close to the side wall 12 to pass through the avoidance notch 20, reducing the risk of the first vertical part 21 obstructing the detection signal, thereby improving the detection accuracy of the detection component 100.

[0117] In some exemplary embodiments, such as Figure 9 As shown, the first reinforcing structure 2 includes at least two reinforcing members 211 and a plurality of supporting members 212. The at least two reinforcing members 211 are arranged in parallel and spaced apart, and the plurality of supporting members 212 are arranged at intervals between two adjacent reinforcing members 211. The plurality of supporting members 212 abut against the two adjacent reinforcing members 211 respectively.

[0118] For example, if the first reinforcing structure 2 has only a first vertical portion 21, then the first vertical portion 21 specifically includes a plurality of reinforcing members 211 and a plurality of supporting members 212; if the first reinforcing structure 2 has a first horizontal portion 22 and a first vertical portion 21, then the first horizontal portion 22 and the first vertical portion 21 may each include a plurality of reinforcing members 211 and a plurality of supporting members 212.

[0119] For example, if the first reinforcing structure 2 only has a first vertical portion 21, multiple reinforcing members 211 are arranged along the length direction of the middle frame 1, and multiple supporting members 212 are arranged along the height direction of the middle frame 1. For example, the number of reinforcing members 211 is two, and the two reinforcing members 211 are arranged in parallel and spaced apart. The number of supporting members 212 is seven, and the seven supporting members 212 are disposed between the two reinforcing members 211, and the two ends of the supporting members 212 along the length direction of the middle frame 1 respectively abut against the two reinforcing members 211. This embodiment does not limit the number of reinforcing members 211 and supporting members 212, and can be adjusted according to the actual production situation.

[0120] With this configuration, the first reinforcing structure 2 is not a single reinforcing rib structure, but has multiple reinforcing members 211, increasing the structural strength of the middle frame 1. At the same time, two adjacent reinforcing members 211 are connected by multiple supporting members 212. The supporting members 212 act as intermediate connections while increasing the structural strength of the first reinforcing structure 2, further improving the overall strength of the middle frame 1.

[0121] This embodiment also provides an air conditioner, such as Figure 11 As shown, the air conditioner includes a mid-frame structure.

[0122] In the air conditioner provided in this embodiment, the first reinforcing structure 2 of the middle frame structure is disposed on the middle frame 1. The first reinforcing structure 2 acts as a reinforcing rib, improving the overall structural strength of the middle frame 1 without affecting the thickness of the entire unit. An avoidance notch 20 is provided on the side of the first reinforcing structure 2 away from the middle frame 1. The avoidance notch 20 is used to avoid the detection signals transmitted and received by the detection component 100, reducing the possibility of the first reinforcing structure 2 obstructing the detection signals, increasing the detection range of the detection signals, and thus improving the detection accuracy of the detection component 100.

[0123] For example, the air conditioner includes a detection component 100, which is mounted on the mounting portion 10 of the middle frame structure. The detection component 100 can be fixedly disposed on the mounting portion 10 of the middle frame structure, with good integrity and fixing effect; or, the detection component 100 can be detachably connected to the mounting portion 10 of the middle frame structure, which facilitates the installation and removal of the detection component 100.

[0124] like Figure 12 As shown, the air conditioner includes multiple detection components 100 and multiple mounting parts 10, with corresponding arrangements of the multiple detection components 100, multiple mounting parts 10, and corresponding configurations. Specifically, the detection signal transmission and reception directions of two adjacent detection components 100 located on both sides of the first reinforcing structure 2 are arranged facing each other. It should be noted that "facing each other" means that the detection signal transmission and reception directions of the two detection components 100 are arranged in opposite directions, so that the detection signals transmitted and received by the two detection components 100 converge towards each other, i.e., the detection signals transmitted and received by the two detection components 100 converge towards each other.

[0125] like Figure 12 As shown, the detection signals transmitted and received by the signal elements 120 of two adjacent detection components 100 are both directed toward the first reinforcing structure 2. By utilizing the avoidance gap 20 corresponding to the first reinforcing structure 2, the detection signals transmitted and received by the two adjacent detection components 100 can be avoided simultaneously, thereby improving the avoidance effect and reducing production costs.

[0126] In an exemplary embodiment, the signal elements 120 corresponding to two adjacent detection components 100 are arranged in a trumpet-shaped structure, that is, the signal elements 120 corresponding to two adjacent detection components 100 are arranged in a figure-eight shape or an inverted figure-eight shape, with the figure-eight and inverted figure-eight shapes being alternately arranged.

[0127] For example, the first reinforcing structure 2 is located between two adjacent second reinforcing structures 3; and / or, the second reinforcing structure 3 is located between two adjacent first reinforcing structures 2. That is, the first reinforcing structures 2 and the second reinforcing structures 3 are staggered to reduce the situation where the structural strength of a local area of ​​the middle frame 1 is too large or too small, and to ensure the balance of the overall structural strength of the middle frame 1.
