Description

Technical Field

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

[0002] The air conditioner mainly includes a compressor, an indoor heat exchanger, a throttling component and an outdoor heat exchanger that form a refrigerant main circuit. The refrigerant circulates in the circuit formed by the compressor-condenser-throttling component-evaporator-compressor, and with the phase change of the refrigerant, it can provide air with a suitable temperature to the indoor space. For example, when the air conditioner is in heating mode, the indoor heat exchanger acts as a condenser that releases heat, and when the air conditioning system is in cooling mode, the indoor heat exchanger acts as an evaporator that releases cold.

[0003] The air conditioner includes an outdoor part and an indoor part. Usually, the outdoor heat exchanger and the compressor are arranged in the outdoor part, and the indoor heat exchanger is arranged in the indoor part. Based on this, the air conditioner mainly includes two types of air conditioners, one is an air conditioner with separate outdoor and indoor parts (such as the outdoor part is usually called the outdoor unit, and the indoor part is usually called the indoor unit), and the other is an air conditioner with integrated outdoor and indoor parts (such as window air conditioners, parking air conditioners, etc.). The indoor part and / or the outdoor part usually have a shell. When the indoor part and the outdoor part are transported or carried in daily operations, there may be a problem that the shell is deformed or even damaged due to collisions and other phenomena.

[0004] Accordingly, the art needs a new technical solution to solve the above problems. Summary of the invention

[0005] Technical issues

[0006] The present invention is proposed to solve the above technical problems at least to a certain extent.

[0007] Technical Solution

[0008] In view of this, the present invention provides an air conditioner, which includes an outdoor part and an indoor part, the outdoor part and / or the indoor part include a shell and a condenser and an evaporator arranged in the shell, the shell includes: a base plate; a back plate, which is fixedly connected to the base plate; and a cover having a connecting structure allowing air circulation outside and inside the shell; wherein a first aspect of the cover abuts the base plate, and a second aspect of the cover is at least fixedly connected to the back plate.

[0009] Through such a configuration, a specific structural form of the shell of the air conditioner is provided.

[0010] Based on such a structure, the cover shell ensures the reliability of connection through the abutment with the bottom plate and the connection with the back plate, thereby effectively preventing the cover shell from being deformed or even damaged due to collision during transportation.

[0011] It is understandable that those skilled in the art can determine the relative position relationship between the abutment position and the fixed connection position according to actual needs, such as: different parts can include one of the abutment or the fixed connection; the same part can include both the abutment and the fixed connection; etc.

[0012] It is understandable that those skilled in the art can determine the fixing method of the cover and the back plate and the relative position between the fixing positions of the two and the fixing positions of the bottom plate and the back plate according to the actual situation. For example, the two fixing methods can be the same or different, and the two fixing positions can be directly the same position (such as the bottom plate, the cover, and the back plate are connected by the same fastener), adjacent positions, or positions staggered from each other. For example, the bottom plate, the cover, and the back plate are connected by the same fastener. In this case, the connection between the cover and the back plate at least includes the connection between the cover and the bottom plate.

[0013] For the above air conditioner, in a possible implementation manner, a portion of the cover shell close to the bottom plate is connected to the back plate at a first position, and the bottom plate is connected to the back plate at a position corresponding to the second position.

[0014] Wherein, the first position and the second position are staggered in at least one direction.

[0015] Through such a structure, a possible connection mode between the cover shell, the base plate and the back plate is provided.

[0016] It is understandable that those skilled in the art can flexibly determine the specific staggering method and specific staggering degree of the (first and second) positions according to actual needs. For example, the two positions can be staggered to different degrees along one or more of the directions (front, back), (high, low), and (left, right).

[0017] For the above air conditioner, in a possible implementation manner, the first position and the second position are staggered along a height direction of the shell.

[0018] Through such a configuration, a possible relative position relationship between the first position and the second position is provided.

[0019] For the above-mentioned air conditioner, in a possible embodiment, the cover includes a cover body and a first cover extension portion extending from the cover body in a direction close to the back plate, the first cover extension portion is fixedly connected to the back plate at a position corresponding to the first position, and in an assembled state, at least a portion of the first cover extension portion abuts against the bottom plate.

[0020] Through such a structure, a connection relationship between the cover and the back plate is provided.

[0021] It is understandable that those skilled in the art can determine the specific position where the cover extension part abuts against the bottom plate, the specific abutment method, and the structural difference between the abutment part and the non-abutment part according to the actual situation. For example, through such a configuration, the cover extension part is a strip structure with uniform structure, and the part of the strip structure close to the end abuts against the bottom plate by extending into the bottom plate.

[0022] For the above air conditioner, in a possible implementation, the first cover shell extension portion includes a first portion and a second portion distributed along the height direction of the shell, wherein the first portion is fixedly connected to the back plate, and the second portion abuts against the bottom plate.

[0023] Through such a construction, a specific structural form of the first cover shell extension portion is provided.

[0024] For the above air conditioner, in a possible implementation manner, a width of the second portion is smaller than at least a portion of a width of the first portion.

[0025] Through such a composition, a specific relationship between the first part and the second part is given.

[0026] For the above-mentioned air conditioner, in a possible embodiment, the base plate includes a base plate main body and a first base plate extension portion extending upward from the base plate main body, the first base plate extension portion is fixedly connected to the back plate at a position corresponding to the second position, and in an assembled state, the first cover shell extension portion abuts against an outer wall of the first base plate extension portion.

[0027] Through such a structure, a connection relationship between the bottom plate and the back plate is provided.

[0028] For the above-mentioned air conditioner, in a possible implementation manner, the cover further includes a second cover extension portion extending from the cover body toward the direction close to the base plate, and in an assembled state, the second cover extension portion covers the outer side of the base plate.

[0029] Through such a structure, a method for achieving abutment between the cover and the bottom plate is provided.

[0030] For the above air conditioner, in a possible implementation, the base plate further includes a second base plate extension portion extending upward from the base plate main body, wherein the second cover shell extension portion is covered on the outer side of the base plate via the second base plate extension portion.

[0031] In this way, a specific structural form of the base plate is given.

[0032] Regarding the above-mentioned air conditioner, in a possible implementation manner, the air conditioner is an air conditioner in which the indoor part and the outdoor part are separately or integratedly arranged. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0043] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "setting", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, an indirect connection through an intermediate medium, or the internal connection of two components.

[0044] In addition, in order to better illustrate the present invention, many specific details are given in the specific embodiments below, and those skilled in the art should understand that the present invention can also be implemented without certain specific details. In some examples, the principles of air conditioners well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present invention.

[0045] Reference Figures 1 to 5 , Figure 1 A schematic diagram showing the structure of a window machine according to an embodiment of the present invention is shown. Figure 2 A schematic diagram showing the structure of a window machine according to an embodiment of the present invention is shown. Figure 3 A schematic diagram showing the structure of a housing of a window machine according to an embodiment of the present invention is shown. Figure 4 A partial schematic diagram showing a housing of a window machine according to an embodiment of the present invention Figure 1 , Figure 5 A partial schematic diagram showing a window machine according to an embodiment of the present invention Figure 2 .like Figures 1 to 5As shown, the window machine 100 mainly includes an indoor part and an outdoor part integrated in the same housing. First of all, it should be noted that the functional components of the window machine mainly form the compressor, indoor heat exchanger, outdoor heat exchanger, throttling component (such as capillary, electronic expansion valve, etc.) and four-way valve of the main refrigerant circuit. Through the circulation of the refrigerant in the circuit formed by the compressor-condenser-throttling component-evaporator-compressor, accompanied by the phase change of the refrigerant, the surface of the indoor heat exchanger can release cold / heat. By switching the connection mode of the four-way valve, the window machine can have a conventional cooling mode and heating mode. Specifically, when the refrigerant circulates along the loop of the compressor → indoor heat exchanger → outdoor heat exchanger → compressor, the window machine is in a heating cycle. That is: when the window machine is in the heating mode, the indoor heat exchanger acts as a condenser that releases heat. When the refrigerant circulates along the loop of the compressor → outdoor heat exchanger → indoor heat exchanger → compressor, the window machine is in a refrigeration cycle. That is, when the window unit is in cooling mode, the indoor heat exchanger acts as an evaporator that releases cooling energy.

[0046] In a possible embodiment, the housing includes a housing 1 having a generally U-shaped structure, a bottom plate 2 located at the bottom of the housing, a back plate 3 located at the rear (outdoor side) of the housing, and a front panel 4 located at the front of the housing. The housing 1 is provided with an outdoor communication structure 51 that allows the surface of the outdoor heat exchanger of the outdoor part to exchange heat with the air of the outdoor environment, and the front panel 4 is provided with an indoor communication structure 52 that allows the surface of the outdoor heat exchanger of the outdoor part to exchange heat with the air of the indoor space. As in this example, both the outdoor communication structure 51 and the indoor communication structure 52 are grid-like structures.

[0047] Different from the split-type air conditioner, the window air conditioner is based on the integrated arrangement of the outdoor part and the indoor part. By fixing it to the window of the room, the outdoor part can be connected to the outdoor environment, and the indoor part can be connected to the indoor space. For example, a plurality of snap-in structures 6 are usually provided on the cover 1 to realize the fixation of the window air conditioner on the window of the room. As in this example, the structural form of the snap-in structure is: three strip holes extending and arranged in the vertical direction are respectively provided on the left and right sides of the U-shaped cover 1, and a pair of snap-in plates arranged opposite to each other are extended from the cover at the position corresponding to the strip holes. When the window air conditioner is fixed to the position corresponding to the window of the room, the two sides of the window glass of the room are clamped between the pair of snap-in plates.

[0048] In one possible implementation, according to Figure 3In the orientation shown, the cover 1 includes a cover body 10, a first cover extension part 11 (a, b) extending from the front side of the cover body corresponding to the two side ends of the U-shaped structure respectively toward the direction close to the back plate, and a second cover extension part 12 (a, b) extending from the lower side of the cover body corresponding to the two side ends of the U-shaped structure respectively toward the direction close to the bottom plate. Taking the first cover extension part 11 (b) as an example, it mainly includes a first part 111 located at the top and a second part 112 located near the bottom plate, wherein the first part is mainly used to achieve a fixed connection between the first cover extension part 11 (b) and the back plate, and the second part is mainly used to achieve abutment between the first cover extension part 11 (b) and the bottom plate. Exemplarily, the first part is a strip structure of equal width, and the second part is a strip structure located at the end position of the first part, the width of which is narrower than that of the first part.

[0049] In a possible embodiment, the bottom plate 2 includes a bottom plate body 20, a first bottom plate extension portion 21 (corresponding to the side of the back plate) extending upward from the bottom plate body between the two sides corresponding to the U-shaped structure, and two second bottom plate extension portions 22 corresponding to the two sides of the U-shaped structure. The first cover extension portions 11 (a, b) are both connected to the back plate and abut against the outer walls of the two ends of the first bottom plate extension portion 21, and the second cover extension portions 12 (a, b) are respectively abutted to the positions of the bottom plate body 20 corresponding to the two sides of the U-shaped structure through the second bottom plate extension portions 22.

[0050] Main reference Figure 4 , the figure shows the connection relationship of the part of the shell near the right side. The first bottom plate extension part 21 has an extension end 211 near the intersection of the back plate and the cover shell (the edge of the right side of the shell), and the structure of the extension end is roughly a trapezoidal structure. The first part 111 of the first cover shell extension part 11 (b) and the back plate 3 are fixedly connected at a first position by means of a first screw 71 (b), and the extension end 211 of the first bottom plate extension part 21 and the back plate 3 are fixedly connected at a second position located below the first position by means of a second screw 72 (b). At the same time, the second part 112 abuts against the part of the extension end 211 near the right side.

[0051] according to Figure 4 In this example, there is a gap between the lower side of the first part and the upper bottom side of the extension end, so that interference between the fixed connection methods corresponding to the first position and the second position can be effectively prevented. The left side of the second part abuts against the right waist of the extension end but does not abut over a large area, and such cooperation can effectively prevent interference between the fixed connection method corresponding to the second position and the abutment method corresponding to the second position.

[0052] In addition, the position where the base plate main body 20 abuts against the second cover shell extension portion 12(b) is slightly higher than the portion thereof close to the first base plate extension portion 21. Thus, in the assembled state, the second cover shell extension portion 12(b) abutting against the base plate main body 20 is in a suspended arrangement that is not in contact with the ground. Since the second cover shell extension portion 12(b) will not contact the bottom such as windows or the bottom of a vehicle or the ground during transportation, the reliability of the abutment will not be disturbed.

[0053] In addition, in the assembled state, the bottom edge of the housing body is slightly higher than the bottom edge of the second bottom plate extension 22. This assembly method can further ensure that the housing is suspended in the air. In addition, a small portion of the housing structure is removed near the bottom corner, so that the possibility of deformation of the housing at the bottom corner due to collision is completely avoided by hollowing out the structure.

[0054] Main reference Figure 5 , the figure shows the connection relationship of the part of the shell near the left side. In this example, the first bottom plate extension part 21 also has a protruding end 211 near the position where the back plate and the cover shell intersect (the edge of the left side of the shell), and the structure of the protruding end is also roughly a trapezoidal structure, but the bottom side of the trapezoid is significantly wider than the right side. Similar to the structure on the right side, the first part 111 of the first cover shell extension part 11 (a) on the left side and the back plate 3 are fixedly connected at the first position on the left side by means of the first screw 71 (a), and the protruding end 211 of the first bottom plate extension part and the back plate 3 are fixedly connected at the second position below the first position on the left side by means of the second screw 72 (a). In this example, the first position and the second position on the left and right sides roughly correspond in the height direction. At the same time, the second part 112 abuts against the part of the protruding end 211 near the left side.

[0055] In accordance with the fact that the bottom edge of the trapezoid of the extended end is significantly wider than the right side, the width of the first part and the second part of the first shell extension 11 (a) are also significantly wider than the right side. As in this example, the first part abuts against the waist area and the upper bottom edge area (along the width direction) of the extended end.

[0056] It can be seen that in the window machine of the present invention, the assembly of the shell is achieved by combining abutment and fixed connection between the cover, the bottom plate and the back plate. Through the connection relationship between the first cover extension part and the second cover extension part, under the premise of ensuring the connection reliability of the shell, compared with the common structure on the market where the cover is fully wrapped in the bottom plate, the probability of deformation or even damage of the cover due to collision during transportation and other situations is reduced. Especially for the bottom corner area of ​​the shell, through the design of the bottom extension part combined with its fixed connection and abutment with the first cover extension part, the possibility of collision of the cover at the bottom corner is effectively avoided, that is, the possibility of deformation of the cover in the bottom corner area is completely avoided, thereby improving the structural stability of the shell of the window machine and ensuring the integrity of the window machine.

[0057] It should be noted that, although the above specific structure is introduced as an example, those skilled in the art will understand that the present invention should not be limited thereto. In fact, those skilled in the art can flexibly adjust the relevant structure according to the actual application scenario, such as adjusting the length ratio and width ratio between the first part and the second part, the structural form of the extended end, and the abutment position and abutment area between the extended end and the first part; etc.

[0058] In addition, those skilled in the art will appreciate that, although some embodiments described herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present invention and form different embodiments. In the claims of the present invention, any one of the claimed embodiments may be used in any combination.

[0059] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments, but it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
