Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a middle frame assembly and an air conditioner. Background Art

[0002] Air conditioning is a room air conditioner that adjusts temperature and humidity. A wall-mounted air conditioner is a unit used to provide air temperature changes to a space area (usually closed). Its function is to adjust the temperature, humidity, cleanliness and air flow rate of the air in the room (or closed space or area) to meet the requirements of human comfort or process.

[0003] However, in the existing air conditioner, the air guide plate of the air conditioner is easy to get stuck in the air inlet during rotation, or the air guide plate of the air conditioner is easy to get stuck in the air inlet after being deformed by external force, causing the air guide plate to malfunction and affect the operating efficiency of the air conditioner. Summary of the invention

[0004] The present invention solves the technical problem that during the rotation of the air guide plate of the air conditioner, the air guide plate is easily stuck in the air inlet, resulting in low operating efficiency of the air conditioner.

[0005] To solve the above problems, the present invention provides a middle frame assembly, comprising: a middle frame body; an air outlet, arranged on the middle frame body, the air outlet comprising an upper end surface and a lower end surface arranged oppositely; wherein the lower end surface is provided with a guide portion.

[0006] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: a guide portion is provided on the lower end surface of the air outlet, which, when the air conditioner is turned off, limits the position of the air guide plate of the air conditioner during rotation, thereby preventing the air guide plate from getting stuck in the air outlet during rotation and being unable to open, thereby improving the user experience.

[0007] In an optional embodiment, the guide portion includes: at least one guide rib protruding from the lower end surface.

[0008] It can be understood that at least one guide rib is provided and the lower end surface of the protrusion is provided to play a limiting role during the rotation of the air-conditioning air guide plate to prevent the air-conditioning air guide plate from being stuck in the air outlet.

[0009] In an optional embodiment, the guide rib includes a first side surface away from the air outlet, the first side surface is inclined, and the inclination direction of the first side surface is inclined toward the air outlet.

[0010] It can be understood that the guide ribs are arranged to include a first side surface away from the air outlet, which is inclined toward one side of the air outlet, so as to prevent the end of the first side surface away from the lower end surface from pressing against the back of the air-conditioning air guide plate during the rotation of the air-conditioning air guide plate, thereby causing an early limit, so that the gap between the air-conditioning air guide plate and the lower end surface of the air outlet is too large during the closing process of the air conditioner; the first side surface is inclined toward one side of the air outlet, so that during the rotation of the air-conditioning air guide plate, the end of the first side surface close to the lower end surface presses against the back of the air-conditioning air guide plate to form a limit; the gap between the air-conditioning air guide plate and the lower end surface of the air outlet during the closing process of the air conditioner is greatly reduced, thereby preventing the interior of the air conditioner from being seen from the outside, and preventing external dust from entering the interior of the air conditioner from the air inlet.

[0011] In an optional embodiment, the first side surface is a bent surface.

[0012] It is understandable that the strength of the guide ribs is increased.

[0013] In an optional embodiment, the guide rib further includes a second side surface close to the air outlet, the second side surface is inclined, and the second side surface is inclined away from the air outlet.

[0014] It can be understood that the second side surface is tilted to form a triangular protrusion with the first side surface; the strength of the guide rib protrusion is greatly increased; at the same time, on the one hand, in extreme cases, the air guide plate of the air conditioner slides into the air outlet along the first side surface of the guide rib due to excessive deformation during rotation, and can also slide out of the air outlet along the tilted direction of the second side surface; on the other hand, the first side surface and the second side surface of the guide rib are tilted, which is conducive to guiding the airflow and reducing surging.

[0015] In an optional embodiment, it also includes: at least one anti-condensation groove, which is provided on the surface of the lower end surface and extends along the length direction of the lower end surface.

[0016] It can be understood that the provision of the anti-condensation groove can increase the residence time of the airflow in the anti-condensation groove, increase the lateral flow of air along the anti-condensation groove, and prevent condensation from forming on the surface of the lower end face of the air outlet.

[0017] In an optional embodiment, the guide portion includes: at least one guide rib, the guide rib protruding from the anti-condensation groove.

[0018] It can be understood that arranging the guide rib part in the anti-condensation groove is beneficial to improving the support for the limiting force point of the guide rib.

[0019] In an optional embodiment, the guide rib includes a first side surface away from the air outlet and an opposite second side surface; the first side surface is inclined toward the air outlet; and the first side surface and the second side surface are arranged to be inclined toward each other.

[0020] It can be understood that the first side surface is inclined toward the air outlet, and the first side surface and the second side surface are inclined toward each other; this is beneficial for guiding the airflow and reducing the surging phenomenon.

[0021] In an optional embodiment, the anti-condensation groove includes a first side wall away from the air outlet, and at least a portion of the first side wall extends upward to form at least one first extension portion; the first extension portion forms the guide portion.

[0022] It can be understood that by extending the first side wall to form the guide portion, the overall structure is more concise, the design is simpler, and demoulding is more convenient.

[0023] In an optional embodiment, a side of each of the first extension portions away from the air outlet is an inclined surface, and the inclined surface is inclined toward the air outlet.

[0024] It can be understood that the inclined surface is arranged to be inclined toward the side of the air outlet, so that during the rotation of the air-conditioning air guide plate, the end of the inclined surface away from the lower end surface is prevented from pressing against the back of the air-conditioning air guide plate; and the end of the inclined surface close to the lower end surface presses against the back of the air-conditioning air guide plate to form a limit; the gap between the air-conditioning air guide plate and the lower end surface of the air outlet is greatly reduced during the closing process of the air conditioner, preventing the interior of the air conditioner from being seen from the outside, and preventing external dust from entering the interior of the air conditioner from the air inlet.

[0025] The present invention further provides an air conditioner, comprising: the middle frame assembly and the air conditioner air guide plate as described in any one of the above embodiments, wherein when the air conditioner air guide plate is in a closed state, the guide portion abuts against the air conditioner air guide plate.

[0026] In summary, the above embodiments of the present application may have one or more of the following advantages or beneficial effects:

[0027] 1) It can prevent the air guide plate from getting stuck in the air outlet during the rotation process, and play a role in limiting the air guide plate of the air conditioner during the rotation process, so as to improve the user experience.

[0028] 2) A limiter is formed to prevent the air guide plate from getting stuck in the air outlet during rotation, and the gap between the air guide plate and the lower end surface of the air outlet is reduced during the closing process of the air conditioner, thereby preventing the interior of the air conditioner from being seen from the outside and preventing external dust from entering the air conditioner from the air inlet.

[0029] 3) The first side surface and the second side surface of the guide rib are inclined to facilitate airflow guidance and reduce surging.

[0030] 4) The setting of the anti-condensation groove can increase the residence time of the airflow in the anti-condensation groove, increase the lateral flow of air along the anti-condensation groove, and prevent condensation from forming on the surface of the lower end face of the air outlet.

DETAILED DESCRIPTION

[0037] The object of the present invention is to provide a middle frame assembly, which, by setting a guide portion on the lower end surface of the air outlet, plays a role in limiting the air guide plate of the air conditioner during rotation, preventing the air guide plate from getting stuck in the air outlet during rotation, so as to improve the user experience.

[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0039] [First embodiment]

[0040] See also Figure 1 A first embodiment of the present invention provides a middle frame assembly 100 , including: a middle frame body 110 and an air outlet 120 .

[0041] For details, see Figure 1 and Figure 2 The air outlet 120 is disposed on the middle frame body 110; the air outlet 120 includes an upper end surface 121 and a lower end surface 122, and the upper end surface 121 and the lower end surface 122 are disposed opposite to each other; see Figure 2 The lower end surface 122 is also provided with a guide portion. By providing the guide portion on the lower end surface 122 of the air outlet 120, when the air conditioner is turned off, it plays a role in limiting the position of the air guide plate of the air conditioner during the rotation process, preventing the air guide plate of the air conditioner from being stuck in the air outlet 120 during the rotation process, so as to improve the user experience.

[0042] For further information, see Figure 2The guide portion includes: at least one guide rib 130, which is protruded from the lower end surface 122. By providing at least one guide rib 130, which is protruded from the lower end surface 122, a limiting effect is played during the rotation of the air guide plate of the air conditioner, so as to prevent the air guide plate of the air conditioner from being stuck in the air outlet 120.

[0043] Preferably, three guide ribs 130 are arranged at intervals, respectively located at the two ends and the middle of the lower end surface 122; so that the limiting support force acting on the air-conditioning air guide plate is evenly distributed, thereby reducing the deformation of the two ends or the middle of the air-conditioning air guide plate close to the lower end surface 122 and sinking into the air outlet 120, thereby affecting the operation of the air conditioner 200.

[0044] Furthermore, the guide rib 130 includes a first side surface 131 away from the air outlet 120 , the first side surface 131 is inclined, and the first side surface 131 is inclined toward the air outlet 120 .

[0045] It should be noted that the guide rib 130 includes a first side surface 131 away from the air outlet 120 and is inclined toward one side of the air outlet 120; the reason why it is inclined toward the air outlet 120 (concave form) rather than in a direction away from the air outlet 120 is that when it is inclined away from the air outlet 120 (convex form), during the closing process of the air-conditioning air guide plate 210, due to the convex first side surface 131, the air-conditioning air guide plate 210 will first contact the top of the first side surface 131, causing premature limitation, and the air-conditioning air guide plate 210 cannot continue to close to the predetermined position. At this time, the gap between the air-conditioning air guide plate 210 and the lower end surface 122 of the air outlet 120 is too large, affecting the appearance.

[0046] Therefore, by tilting the first side surface 131 toward the side of the air outlet 120, when the air-conditioning air guide plate rotates, one end of the first side surface 131 close to the lower end surface 122 presses against the back of the air-conditioning air guide plate to form a limit position; the gap between the air-conditioning air guide plate and the lower end surface 122 of the air outlet 120 is greatly reduced during the closing process of the air conditioner 200, preventing the interior of the air conditioner from being seen from the outside, and preventing external dust from entering the interior of the air conditioner 200 from the air inlet.

[0047] Furthermore, the first side surface 131 is a bent surface, which can improve the strength of the guide rib 130 .

[0048] For example, the first side surface 131 may also be a curved arc surface, which will not be described in detail herein.

[0049] Furthermore, the guide rib 130 further includes a second side surface 132 close to the air outlet 120, the second side surface 132 is inclined, and the second side surface 132 is inclined toward the side away from the air outlet 120. By arranging the second side surface 132 in an inclined manner, a triangular protrusion is formed with the first side surface 131, which greatly increases the protrusion strength of the guide rib 130;

[0050] On the one hand, in extreme cases, the air-conditioning air guide plate 210 may slide into the air outlet 120 along the first side surface 131 of the guide rib 130 due to excessive deformation during rotation, and may also slide out of the air outlet 120 along the inclined direction of the second side surface 132; on the other hand, the first side surface 131 and the second side surface 132 of the guide rib 130 are inclined, which is conducive to guiding the airflow and reducing surging.

[0051] For example, the second side surface 132 may also be a bent surface or a curved arc surface, which will not be described in detail herein.

[0052] Furthermore, the middle frame assembly 100 further includes: at least one anti-condensation groove 123, which is provided on the surface of the lower end surface 122 and extends along the length direction of the lower end surface 122. By providing at least one anti-condensation groove 123, the residence time of the airflow in the anti-condensation groove 123 can be increased, and the air can flow laterally along the anti-condensation groove 123 to form turbulence, avoid laminar flow of the airflow, and cause condensation to form on the surface of the lower end surface 122 of the air outlet 120. Preferably, two anti-condensation grooves 123 are provided side by side on the surface of the lower end surface 122.

[0053] Furthermore, the guide portion includes: at least one guide rib 130 , and the guide rib 130 protrudes from the anti-condensation groove 123 .

[0054] By setting at least one guide rib 130 protruding from the anti-condensation groove 123, on the one hand, partially setting the guide rib 130 in the anti-condensation groove 123 is beneficial to improve the support for the limiting force point of the guide rib 130; on the other hand, dividing the anti-condensation groove 123 into multiple sections of guide grooves can increase the residence time of the airflow in the multiple sections of anti-condensation grooves 123.

[0055] Furthermore, the guide rib 130 includes a first side surface 131 away from the air outlet 120 and an opposite second side surface 132; the first side surface 131 is inclined toward the air outlet 120; and the first side surface 131 and the second side surface 132 are arranged to be inclined toward each other. By inclining the first side surface 131 toward the air outlet 120, and the first side surface 131 and the second side surface 132 are arranged to be inclined toward each other, it is beneficial to guide the airflow and reduce the surging phenomenon.

[0056] Furthermore, the anti-condensation groove 123 includes a first side wall away from the air outlet 120, at least part of the first side wall extends upward to form at least one first extension portion; the first extension portion forms the guide portion. By extending part of the first side wall to form the guide portion, the overall structure is more concise, the design is simpler, and the demoulding is more convenient.

[0057] Furthermore, each of the first extensions has an inclined surface on the side away from the air outlet 120, and the inclined surface is inclined toward the air outlet 120. By setting the inclined surface to be inclined toward the air outlet 120, the end of the inclined surface away from the lower end surface 122 is prevented from pressing against the back of the air guide plate during the rotation of the air guide plate; and the end of the inclined surface close to the lower end surface 122 presses against the back of the air guide plate, forming a limit.

[0058] Then, the gap between the air guide plate of the air conditioner 200 and the lower end surface 122 of the air outlet 120 is reduced during the closing process of the air conditioner 200, thereby preventing the interior of the air conditioner from being seen from the outside and preventing external dust from entering the interior of the air conditioner 200 from the air inlet.

[0062] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention.
