Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, specifically to the technical field of air conditioners, and in particular to a middle frame anti-condensation structure and an air conditioner thereof. Background Art

[0002] Air conditioning is an air conditioner, which is a device that uses artificial means to adjust and control the temperature, humidity, flow rate and other parameters of the ambient air in a building. As a common electrical appliance to improve the comfort of the living environment, people have higher and higher requirements for air conditioning, especially the anti-condensation effect.

[0003] In the air conditioner, especially in cooling mode, a large amount of cold air will escape from the joint between the air guide plate and the middle frame air outlet, causing a large amount of condensation to appear below the middle frame air outlet. The existing solution is to set a wind direction correction convex strip at the joint between the air outlet and the air guide plate to allow as much cold air as possible to pass through the joint between the air outlet and the air guide plate to improve the condensation situation. However, a part of the cold air will still flow to the joint between the air outlet and the air guide plate and escape, causing condensation at the joint between the air outlet and the air guide plate. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art described above, the utility model provides a middle frame anti-condensation structure and an air conditioner thereof, which can solve the problem of condensation generated at the air outlet of the air conditioner.

[0005] The technical solution adopted by the utility model to solve the problem is:

[0006] A middle frame anti-condensation structure is arranged at the air outlet of the middle frame, and is characterized in that a side wall of the air outlet is provided with a stepped feature plate, which is used to be spliced ​​with an air guide plate, and the stepped feature plate is provided with an air guide structure at a height higher than the splicing position, and the air guide structure is used to guide the airflow of the air outlet to pass through the gap at the splicing position of the air guide plate and the stepped feature plate, and the splicing position of the stepped feature plate and the air guide plate is a cavity structure.

[0007] By adopting the above scheme, the wind guide structure will appropriately raise the wind direction passing through it, thereby guiding most of the air to pass through the joint of the air guide plate and the step feature plate, avoiding the formation of condensation at the bottom of the air guide plate and the middle frame when the air flows through the joint. Even if a small amount of cold air escapes from the joint, since the joint of the step feature plate and the air guide plate is a cavity structure, the thermal conductivity of the air is low, which can play a role in heat insulation, thereby effectively solving the problem of condensation at the bottom of the middle frame.

[0008] Furthermore, the step feature plate includes a first step surface, a second connection surface and a third step surface which are connected in sequence, the third step surface is in contact with the air guide plate, and the air guide structure is arranged on the first step surface.

[0009] By adopting the above solution, the third step surface facilitates the splicing of the air guide plate and reduces the escape of cold air. The air guide structure is arranged on the first step surface, which facilitates the appropriate upward correction of the airflow just passing through the step feature plate, further reducing the escape of cold air.

[0010] Furthermore, the third stepped surface is connected to a fourth inclined surface bent toward the leeward side, and the fourth inclined surface is inclined toward a direction away from the splicing surface of the wind guide plate.

[0011] By adopting the above solution, the cold air flow escaping from the joint of the step feature plate and the air guide plate is prevented from adhering to the wall, and the vortex generated when the cold air is separated is reduced, thereby preventing condensation.

[0012] Furthermore, the inclination angle of the fourth inclined surface is 3-10°.

[0013] By adopting the above solution, the escaped cold air flow can be effectively prevented from adhering to the wall and generating eddies. If the angle is too small, the effect of improving condensation is not significant, and if the angle is too large, the overall structural stability and integrity of the product will be affected.

[0014] Furthermore, the wind guide structure is a wind direction correction convex strip, and the wind direction correction convex strip is higher than the height of the joint between the wind guide plate and the step characteristic plate.

[0015] By adopting the above solution, the wind direction can be guided to rise appropriately, and the upward angle of the wind direction can be controlled by the raised angle of the wind direction correction convex strip.

[0016] Furthermore, the wind direction correction convex strip is arranged on a side of the first step surface close to the wind guide plate.

[0017] By adopting the above solution, the amount of cold air entering the joint between the stepped feature plate and the air guide plate is reduced.

[0018] Furthermore, the wind guide structure is a heightened section arranged on the first step surface, and the heightened section is higher than the height at which the wind guide plate and the step feature plate are spliced.

[0019] By adopting the above solution, the wind direction can be guided to rise appropriately. At the same time, when designing the middle frame, the heightened section can be designed into the stepped feature plate, which is convenient for production and has a significant effect in guiding the wind direction.

[0020] Furthermore, the cavity structure is a negative pressure cavity.

[0021] By adopting the above solution, the thermal conductivity of the negative pressure cavity is lower, which improves the thermal insulation effect of the cavity structure and prevents condensation at the bottom.

[0022] Furthermore, the cavity structure is filled with aerogel thermal insulation material.

[0023] By adopting the above scheme, the thermal conductivity of the aerogel thermal insulation material is lower than the thermal conductivity of air.

[0024] Furthermore, the first stepped surface, the second connecting surface, the third stepped surface and the fourth inclined surface are integrally formed.

[0025] By adopting the above solution, the integrity of the anti-condensation structure of the middle frame is improved, the problems such as the air flow channel irregularity caused by the structural seam of the split design are reduced, and the production of the middle frame is facilitated.

[0026] The utility model also provides an air conditioner, including an air conditioner body, the air conditioner body including: including the above-mentioned middle frame anti-condensation structure and an air guide plate, the air guide plate is provided with a lap boss and a splicing surface, the splicing surface of the air guide plate is provided with the lap boss in the direction of the step feature plate, which is used to overlap with the third step surface, the splicing surface is arranged opposite to the fourth inclined surface, and the splicing surface is inclined in the direction away from the step feature plate.

[0027] By adopting the above solution, the setting of the joint surface is used to facilitate the movement of the air guide plate on the one hand, and to further expand the space between the joint surface and the fourth inclined surface on the other hand, thereby further reducing the vortex generated during the separation of cold air.

[0028] In summary, the middle frame anti-condensation structure provided by the utility model has the following technical effects:

[0029] 1. The step feature plate is provided with an air guide structure higher than the height of the joint, which adjusts the wind direction of the airflow passing through the step feature plate so that the wind direction is appropriately upward, preventing the airflow from escaping from the overlap gap between the air guide plate and the step feature plate, thereby avoiding the formation of condensation on the air guide plate and the bottom of the middle frame;

[0030] 2. The cavity structure can play a certain role in heat insulation and prevent condensation at the bottom of the step feature plate;

[0031] 3. The fourth inclined surface is inclined in a direction away from the air guide plate to prevent the cold air flow from flowing against the wall and reduce the vortex generated when the cold air separates from the side wall, thereby reducing noise and condensation.

DETAILED DESCRIPTION

[0040] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described and discussed below in conjunction with the accompanying drawings of the present invention. Obviously, what is described here is only a part of the examples of the present invention, not all the examples. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0041] In order to facilitate the understanding of the embodiments of the present utility model, the following will be further explained by taking specific embodiments as examples in conjunction with the drawings, and each embodiment does not constitute a limitation on the embodiments of the present utility model.

[0042] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0044] See also Figure 1-Figure 6 The utility model discloses a middle frame anti-condensation structure, a middle frame assembly and an air conditioner thereof, wherein the middle frame anti-condensation structure, referring to Figure 3 As shown, a stepped feature plate is provided at the air outlet 230 of the middle frame, and a side wall of the air outlet 230 is provided, which is used to overlap with the air guide plate 110, and guide the wind of the air outlet 230 out through the air guide plate 110. In this embodiment, the stepped feature plate is provided at the joint of the middle frame and the air guide plate 110. Specifically, the stepped feature plate includes a first stepped surface 211, a second connecting surface 212 and a third stepped surface 213 connected in sequence, and the third stepped surface 213 is overlapped with the air guide plate 110. The first stepped surface 211 is provided with an air guide structure, and the air guide structure is used to guide the airflow of the air outlet 230 to pass through the gap at the joint of the air guide plate 110 and the stepped feature plate. The joint of the stepped feature plate and the air guide plate 110 is a cavity structure 220.

[0045] Specifically, refer to Figure 3 As shown, the first step surface 211, the second connecting surface 212 and the third step surface 213 are connected in sequence in a Z-shaped design (i.e., they are bent 90 degrees in sequence), and the third step surface 213 is used to overlap with the air guide plate 110. Specifically, the splicing surface of the air guide plate 110 is provided with an overlapping boss 111 facing the direction of the step feature plate, and the overlapping boss 111 is close to the air outlet 230. The overlapping boss 111 of the air guide plate 110 is overlapped on the third step surface 213, and the overlapping surface of the third step surface 213 and the overlapping surface of the overlapping boss 111 are fitted to achieve the overlapping of the third step surface 213 and the air guide plate 110. The end of the third step surface 213 located below the overlapped boss is bent downward to form a fourth inclined surface 214. The fourth inclined surface 214 is directly opposite to the joint surface of the air guide plate 110, and the fourth inclined surface 214 is inclined in the direction of the joint surface of the principle air guide plate 110, so as to prevent the cold air flow escaping from the joint of the step feature plate and the air guide plate 110 from flowing along the wall, and also reduce the vortex generated when the cold air flow separates from the step feature plate and the air guide plate 110, thereby preventing condensation. The inclination angle of the fourth inclined surface 214 is 3-10°, which is optimal, and can effectively prevent the escaped cold air flow from flowing along the wall and the generation of larger separation vortex. If the angle is too small, the effect of improving condensation is not significant. If the angle is too large, the joint gap between the fourth inclined surface 214 and the joint surface of the air guide plate 110 is large, which affects the overall structural stability and overall aesthetics of the product.

[0046] The first step surface 211, the second connection surface 212, the third step surface 213 and the fourth inclined surface 214 are integrally formed to reduce structural seams. Furthermore, the step feature plate and the middle frame are integrally formed to facilitate the production of the entire middle frame.

[0047] In some embodiments, the wind guide structure may be a raised section 2111 disposed on the first step surface 211, see Figure 3 As shown, the heightened section 2111 is higher than the height of the joint between the air guide plate 110 and the stepped characteristic plate. The heightened section 2111 can guide the wind to rise appropriately, and minimize the wind flow to the joint between the middle frame and the air guide plate 110, thereby making as little cold wind as possible flow out of the joint. In addition, when designing the middle frame, the heightened section 2111 can be directly designed into the stepped characteristic plate, that is, the height of the first step surface 211 is increased, so that the first step surface 211 is higher than the height of the joint between the air guide plate 110 and the stepped characteristic plate. The heightened section 2111 can guide the wind to rise appropriately, and minimize the wind flow to the joint between the middle frame and the air guide plate 110.

[0048] In some embodiments, the wind guide structure can be a wind direction correction convex strip 2112, see Figure 4 As shown, the wind direction correction rib 2112 is higher than the height of the overlap between the air guide plate 110 and the step feature plate. Compared with the heightened section 2111, the wind direction correction rib 2112 design has an upward curved surface on its windward surface. On the one hand, the height requirement for the first step surface 211 can be lower, and the bending of the first step surface 211 can be avoided, that is, the first step surface 211 and the air outlet channel of the middle frame are in the same plane, which enhances the overall structural strength of the middle frame. More importantly, the upward angle of the wind direction can be controlled by the angle of the raised curved surface of the wind direction correction rib 2112, thereby reducing the wind flow to the joint between the middle frame and the air guide plate 110, thereby making as little cold wind as possible flow out of the joint, improving the condensation phenomenon of the air conditioner. It is best to arrange the wind direction correction ridge 2112 on the side of the first step surface 211 close to the air guide plate 110. This position is close to the joint between the step feature plate and the air guide plate 110. If it is arranged far away from this position, a certain amount of airflow will still flow downward, thereby failing to achieve the purpose of minimizing the condensation generated by the cold air flowing into the joint between the step feature plate and the air guide plate 110. The wind direction correction ridge 2112 is arranged on the side of the first step surface 211 close to the air guide plate 110 to minimize the amount of cold air escaping from the joint, thereby achieving the best effect of reducing condensation.

[0049] Reference Figure 3As shown, when a small amount of cold air enters the joint between the step feature plate and the air guide plate 110, or cold air escapes from the gap at the joint to the bottom of the middle frame, the bottom of the middle frame is also the leeward side of the middle frame, and condensation occurs on the leeward side of the middle frame. In the present application, a cavity structure 220 is set at the joint between the step feature plate and the air guide plate 110, and because the thermal conductivity of air is lower than that of the injection molding material of the air conditioner middle frame, it can play a certain role in heat insulation, and can effectively solve the problem of condensation at the bottom of the middle frame.

[0050] In some embodiments, reference Figure 5 As shown, in order to improve the heat insulation effect of the cavity structure 220, the cavity structure 220 can be set as a negative pressure cavity. The specific process of setting it as a negative pressure cavity is as follows: during the production process, the opening of the cavity structure 220 away from the step feature plate can be sealed first, and a small hole can be reserved. The inside of the cavity structure 220 is evacuated through the small hole. After the air is evacuated, the reserved small hole is sealed and blocked to form a negative pressure cavity inside the cavity structure 220. Since the thermal conductivity of air decreases with the decrease of pressure, the thermal conductivity of the negative pressure cavity is lower, thereby improving the heat insulation effect of the cavity structure 220 and reducing the condensation at the bottom of the middle frame.

[0051] In some embodiments, reference Figure 6 As shown, in order to improve the thermal insulation effect of the cavity structure 220, the cavity structure 220 can be filled with aerogel thermal insulation material 221. The aerogel thermal insulation material 221 is light in weight and will not affect the overall weight of the air conditioner. At the same time, the thermal conductivity of the aerogel thermal insulation material 221 is also lower than the thermal conductivity of the air. Therefore, compared with the cavity design, filling with aerogel thermal insulation material 221 can further improve the thermal insulation effect of the cavity structure 220 and more effectively reduce condensation at the bottom of the middle frame.

[0052] Of course, the cavity structure 220 may also be filled with materials with low thermal conductivity such as foamed polyurethane and polystyrene particles to ensure thermal conductivity.

[0053] Principle of this embodiment:

[0054] When the cold air generated by the air conditioner flows to the air outlet 230, the cold air flows through the increased section 2111 of the first step surface 211 or the wind direction correction rib 2112, so that the wind direction is appropriately raised away from the direction of the step feature plate, effectively preventing the wind from flowing into the joint between the step feature plate and the air guide plate 110, and further effectively preventing the condensation phenomenon at the bottom of the step feature plate and the air guide plate 110. When a small part of the cold air flow after passing through the first step surface 211 flows between the second connecting surface 212 and the air guide plate 110, or the cold air flow flows through the gap at the joint to the bottom of the step feature plate and the air guide plate 110, that is, the leeward side of the step feature plate and the air guide plate 110, the cavity structure 220 has a certain heat insulation effect, and for this small part of the cold air flow, the phenomenon of bottom condensation will not occur at all on the leeward side of the step feature plate and the air guide plate 110. After the above small portion of cold air flow passes between the second connecting surface 212 and the air guide plate 110, a part of it will escape from the lap joint between the third step surface 213 and the air guide plate 110, and flow to between the fourth inclined surface 214 and the portion of the air guide plate 110 opposite to the fourth inclined surface 214. Since the fourth inclined surface 214 is arranged to be inclined in the direction away from the air guide plate 110, the cold air flow is avoided from flowing along the wall and the vortex generated when the cold air separates from the wall is reduced, thereby reducing noise and condensation.

[0055] See also Figure 1 and Figure 7 As shown, on the basis of the above-mentioned middle frame anti-condensation structure, the utility model provides an air conditioner, which includes an air conditioner body 100, and the air conditioner body 100 includes: the above-mentioned middle frame anti-condensation structure and an air guide plate 110, the air guide plate 110 is provided with a lap boss 111 and a splicing surface 112, specifically, the splicing surface of the air guide plate 110 is protruding with a lap boss 111 facing the direction of the step feature plate, and the lap boss 111 is close to the air outlet 230, the lap boss of the air guide plate 110 is overlapped on the third step surface 213, and the third step surface 213 is fitted with the lap surface of the lap boss, so as to achieve the overlap of the third step surface 213 and the air guide plate 110. The end of the third step surface 213 located below the overlapping boss is bent downward to form a fourth inclined surface 214. The fourth inclined surface 214 is opposite to the splicing surface of the air guide plate 110. The fourth inclined surface 214 is inclined in the direction away from the splicing surface of the air guide plate 110, and the splicing surface 112 is also inclined in the direction away from the fourth inclined surface 214. On the one hand, it is used to facilitate the movement of the air guide plate 110, and on the other hand, it is used to further expand the space between the splicing surface 112 and the fourth inclined surface 214, so as to avoid the cold air flow escaping from the splicing of the step feature plate and the air guide plate 110 to flow against the wall, and at the same time, it also further reduces the vortex generated during the separation of the cold air, reduces condensation and reduces noise.

[0056] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
