Description

Technical Field

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

[0002] In current air conditioners, the middle frame and the base cooperate to form an air outlet. The corners of the air outlet are subjected to stress concentration and are easily damaged when subjected to external forces, such as falling from a high altitude or falling to the ground during transportation, which further reduces the service life of the air conditioner. Therefore, how to solve the problem of damage caused by force is what current technicians have to face. Summary of the invention

[0003] The problem solved by the present invention is that stress is concentrated at the corners of the air outlet and the parts where the middle frame and the base match, and the parts are easily damaged during falling or dropping.

[0004] In order to solve the above problems, on the one hand, the present invention provides an air conditioner shell, which includes an air outlet, and the air outlet includes a long end face and a short end face, and a junction is formed between adjacent long end faces and short end faces, and a reinforcement portion is provided at at least one of the junctions.

[0005] Compared with the prior art, the beneficial effect achieved by adopting the technical solution is that, through the design of the reinforcement part, the strength of the junction between the long end face and the short end face is enhanced, and its stability is improved. Preferably, the reinforcement part is located near the short end face of the motor, thereby alleviating the stress concentration caused by the weight of the motor. Of course, the reinforcement part can also be set at the junction of multiple adjacent long end faces and short end faces.

[0006] Furthermore, in one embodiment of the present invention, the air conditioner casing also includes a middle frame and a base, and the middle frame cooperates with the base to form the air outlet; the reinforcement part includes a first reinforcement part and a second reinforcement part, the first reinforcement part is located on the middle frame, and the second reinforcement part is located on the base.

[0007] Compared with the prior art, the beneficial effect achieved by adopting the present technical solution is that both the middle frame and the base are provided with reinforcement parts, namely the first reinforcement part and the second reinforcement part; the technical solution provided in this embodiment further reduces the influence of stress through the two reinforcement parts, and makes the middle frame and the base adaptable and can fit tightly.

[0008] Furthermore, in one embodiment of the present invention, the first reinforcement portion includes an overlapping section, a first transition section and a first avoidance section; the second reinforcement portion includes a splicing section, a second transition section and a second avoidance section; the overlapping section and the splicing section are cooperatively connected.

[0009] Compared with the prior art, the beneficial effect achieved by adopting this technical solution is that the connection positions between the various parts of the first reinforcement part are all arc transitions, and similarly, the various parts of the second reinforcement part are also arc transitions, so that the connection between the various parts is smooth and stress concentration is avoided. The first reinforcement part and the second reinforcement part are superimposed up and down, which further improves their strength level.

[0010] Furthermore, in one embodiment of the present invention, the first avoidance section includes an arc transition section, and the first reinforcement portion is transitionally connected to the short end surface via the arc transition section.

[0011] Compared with the prior art, the beneficial effect achieved by adopting the present technical solution is that the arc transition section is used to transition the connection between the first reinforcement part and the short end face, making the connection smoother; and the arc transition can further improve its strength level.

[0012] Furthermore, in one embodiment of the present invention, the length L of the first avoidance section and the second avoidance section is 1 They are all larger than the arc radius R of the arc transition section.

[0013] Compared with the prior art, the beneficial effect achieved by adopting the present technical solution is that, in order to reduce the concentrated stress, the arc radius of the arc transition section should be increased, so that its strength is improved to a certain extent. Therefore, the arc radius is preferably 2 mm or more. Furthermore, the length L of the first avoidance section and the second avoidance section is 1 It should be larger than the arc radius R so that the stress concentration point is moved away from the arc transition section.

[0014] Furthermore, in one embodiment of the present invention, the angle α between the first transition section and the first avoidance section is 20-70°; the angle α between the second transition section and the second avoidance section is 20-70°.

[0015] Compared with the prior art, the beneficial effect achieved by adopting the present technical solution is that the first transition section and the second transition section play a transition role. In order to make the transition more natural and smooth, the angle α between the first transition section and the first avoidance section should not be too large or too small. The preferred solution provided in this embodiment is 20-70°; the same applies to the second reinforcement part.

[0016] Furthermore, in one embodiment of the present invention, the horizontal projection length L of the first transition section and the second transition section is 2 2-10mm.

[0017] Compared with the prior art, the beneficial effect achieved by adopting the present technical solution is that the lengths of the first transition section and the second transition section are limited, while ensuring that the reinforcement plate disperses stress, other functions of the reinforcement plate are not affected, and the design is reasonable.

[0018] Furthermore, in one embodiment of the present invention, the matching width D between the overlapping section and the splicing section is 1-5 mm.

[0019] Compared with the prior art, the beneficial effect achieved by adopting the technical solution is that the middle frame and the base are overlapped and matched through the overlap section and the splicing section, and a certain matching width can further improve their strength, and can also increase the matching surface area between the middle frame and the base, and play a role in limiting. During the transportation process, the relative movement between the middle frame and the base caused by the workers' unintentional bumping is prevented, that is, the relative stability between the two is guaranteed.

[0020] Furthermore, in an embodiment of the present invention, at the position of the long end surface of the air outlet, the middle frame and the base are matched in a planar manner.

[0021] On the other hand, the present invention further provides an air conditioner, which may include the air conditioner casing described in any one of the above embodiments.

[0022] In summary, after adopting the technical solution of the present invention, the following beneficial effects can be achieved: the strength of the corners of the air outlet is increased; and stress concentration at the corners of the air outlet is avoided. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The technical problem to be solved by the present invention is that the air outlet is formed by the cooperation between the middle frame and the base of the air conditioner, and the corners of the air outlet are subjected to stress concentration and are prone to rupture. Therefore, the present invention adds a reinforcement part, and based on stress analysis, smoothly transitions the connection relationship between the various parts. At the same time, the structure and size of the reinforcement part are analyzed and designed, and an air conditioner shell is proposed, which can effectively avoid stress concentration. At the same time, an air conditioner is also provided, including the above-mentioned air conditioner shell.

[0037] 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.

[0038] [First embodiment]

[0039] See also Figure 1The present embodiment provides an air conditioner 2000, including an air conditioner housing 1000, which is provided with an air outlet 100. In cooling mode, the air outlet 100 is used to send cool air into the room to maintain the temperature of the environment. The air outlet 100 is usually a square diffuser, and its four corners are usually stress concentration points, especially the two corners close to the motor side. Due to their heavy weight, they are more obviously affected by stress and are easily damaged when subjected to external forces. Especially in the process of falling, this side often lands first, which is easy to cause damage to the corner and damage the air conditioner. Therefore, based on the above reasons, the present embodiment provides an air conditioner housing 1000, and a reinforcement part is provided at one of the corners of the air outlet 100 close to the motor side to improve its overall strength level.

[0040] Continue to see Figure 1 In a specific embodiment, the air outlet 100 is roughly rectangular, including two oppositely arranged long end faces 110 and two oppositely arranged short end faces 120, and the junction between the upper long end face 110 and the right short end face 120 is easily damaged during the falling process, therefore, the above-mentioned reinforcement part is arranged at this angle to improve its strength level.

[0041] See also Figure 2 The air outlet 100 is formed by the middle frame 200 and the base 300. The reinforcement part includes a first reinforcement part 210 and a second reinforcement part 310; wherein the first reinforcement part 210 is located on the middle frame 200, and the second reinforcement part 310 is located on the base 300; the first reinforcement part 210 and the second reinforcement part 310 are matched with each other, and are Figure 2 It can be seen that the first reinforcement part 210 and the second reinforcement part 310 are stacked up and down, and the first reinforcement part 210 is arranged on the upper part of the second reinforcement part 310, and the two cooperate with each other to form the reinforcement part.

[0042] See also Figure 3 and Figure 4 In a specific embodiment, the first reinforcement portion 210 includes an overlap section 211, a first transition section 212 and a first avoidance section 213; wherein the overlap section 211 is connected to the long end face 110, the first avoidance section is connected to the short end face 120, and the first transition section 212 is used to transitionally connect the overlap section 211 and the first avoidance section 213. In order to avoid stress concentration, arc transitions are used between the long end face 110 and the overlap section 211, between the overlap section 211 and the first transition section 212, and between the first transition section 212 and the first avoidance section 213, so that the two adjacent parts are smoothly connected together. It is worth noting that the purpose of the arc transition is to move the stress concentration point away from the corner of the air outlet 100. Therefore, the transition method is not limited to the above technical solution, and the two connected parts can be smoothly transitioned without generating an angle.

[0043] Continue to see Figure 4 In a specific embodiment, the first avoidance section 213 includes an arc transition section 214, which is used to connect the first reinforcement portion 210 and the short end face 120 adjacent thereto; so that the first reinforcement portion 210 and the short end face 120 have a smooth transition. Based on the principle of stress distribution, the arc radius R of the arc transition section 214 needs to be appropriately increased to avoid stress concentration at the corners, and in order to further improve its strength level, in this embodiment, the arc radius R is preferably not less than 2mm, that is, R≥2mm, which is larger than the arc radius in the prior art, so as to cooperate with the reinforcement portion to improve its strength level. Of course, those skilled in the art can adjust the value of the arc radius for different air conditioners.

[0044] See also Figure 5 and Figure 6 In a specific embodiment, the angle α between the first transition section 212 and the first avoidance section 213 in the first reinforcement part 210 is preferably 20-70°. The angle α is the angle between the first transition section 212 and the reverse extension line of the first avoidance section 213. The first transition section 212 plays a connecting transition role. Therefore, if its inclination angle is too large or too small, it will cause an unnatural transition, thereby affecting the strength of the reinforcement part. Similarly, the length of the first transition section 212 should also be within a reasonable range, which can not only achieve a smooth transition and reduce the negative effects of stress, but also save materials and reduce the actual size of the reinforcement part, so as to achieve significant effects through improvements in details. Based on the mechanical analysis of the reinforcement part, this scheme provides a technical scheme, preferably the projection length L of the first transition section 212 in the horizontal direction 2 The angle α between the first transition section 212 and the first avoidance section 213 and other factors that may affect the stress can be used to make a reasonable choice. Similarly, in the second reinforcement portion 310, the angle α between the second transition section 312 and the second avoidance section 313 is preferably 20-70°, and the horizontal projection length L of the second transition section 312 is preferably 20-70°. 2 Preferably 2-10 mm.

[0045] Continue to see Figure 6 In a specific embodiment, the length L of the first avoidance section 213 and the second avoidance section 313 is 1 Due to the different weights of the various parts of the air conditioner, the stress conditions of the air outlet 100 at different positions are also different, especially at the corners of the air outlet 100, where the stress conditions are complex and more likely to cause stress point concentration. Based on the adjustment of the size of the arc radius R of the arc transition section 214, L 1It is also necessary to adjust according to the arc radius R so that the connection point between the first transition section 212 and the first avoidance section 213 and the connection point between the second transition section 312 and the second avoidance section 313 are located outside the arc transition section 214. In short, the length L of the first avoidance section 213 and the second avoidance section 313 is 1 It should be slightly larger than the arc radius R to avoid stress concentration at the position of the arc transition section 214.

[0046] See also Figure 7-9 In a specific embodiment, the matching width D of the overlapping section (211) and the splicing section (311) is preferably 1-5 mm.

[0047] See also Fig.10 and Fig.11 At the position of the long end surface 110 of the air outlet 100, the middle frame 200 and the base 300 are matched in a plane. The above design ensures that the corner of the air outlet 100 is strong enough, and the plane matching method makes it easy to disassemble the middle frame 200 and the base 300, and will not accommodate dirt.

[0048] [Second embodiment]

[0049] See also Figure 1 and Figure 2 This embodiment provides an air conditioner housing 1000, including an air outlet 100, which is formed by a middle frame 200 and a base 300. On the basis of the first embodiment, a plurality of reinforcement parts are provided at the corners of different positions of the air outlet 100.

[0050] Specifically, the reinforcement part can be located at two corners of the air outlet 100 close to the motor. In the technical solution provided by the embodiment of the present invention, the panel and the middle frame of the air conditioner are integrally formed. Therefore, compared with the prior art, although the assembly steps are simplified, the overall strength is reduced to a certain extent, especially at the corners where stress is concentrated, which is more fragile than the prior art.

[0051] In a specific embodiment, a drop test was performed on the middle frame structure, and it was found that the side close to the motor hit the ground first. Therefore, reinforcement parts are provided at the two corners of the air outlet 100 close to the motor to avoid damage to the corners of the air outlet 100 due to the carelessness of the porters during the transportation of the air conditioner.

[0052] [Third embodiment]

[0053] The technical solution provided in this embodiment aims to avoid stress concentration, and the above purpose is achieved by adding a reinforcement part. Therefore, according to an air conditioner housing provided in the first embodiment, the shape, size and position relationship of the reinforcement part are not limited to the above technical solution.

[0054] In a specific embodiment, the first transition section 212 and the second transition section 312 may be connected and transitioned by using an oblique angle, or other transition methods; for example, the first transition section 212 and the second transition section 312 may be connected and transitioned by an arc or a curve.

[0055] In a specific embodiment, the first avoidance section 213 and the second avoidance section 313 can also be designed as smooth curves. It is worth noting that the connection position between the first transition section 212 and the first avoidance section 213 and the connection position between the second transition section 312 and the second avoidance section 313 need to be outside the arc transition section 214 to avoid stress concentration at the corners.

[0056] In combination with the above two specific embodiments, the edge of the reinforcement portion can also be a multi-segment curve, combining the first transition section 212 and the first avoidance section 213 into a smooth curve, which not only strengthens the strength of the corner but also avoids stress concentration. Similarly, the first transition section 212 and the first avoidance section 213 of each reinforcement portion can have multiple sets of designs to form multiple broken lines. The design method of the second transition section 312 and the second avoidance section 313 is similar.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
