Description

Technical Field

[0001] This application relates to the technical field of air conditioners, and specifically provides a mobile air conditioner. Background Art

[0002] At present, in the mobile air conditioners of related technologies, there are an outdoor heat exchange cavity and an indoor heat exchange cavity which are independent of each other. Among them, components such as a compressor, a condenser, and an outdoor fan are mainly arranged in the outdoor heat exchange cavity, and components such as an evaporator and an indoor fan are mainly arranged in the indoor heat exchange cavity. Among them, the compressor, the evaporator, and the condenser are connected through a refrigerant pipeline to enable the refrigerant to flow. When the refrigerant flows to the evaporator, it mainly exchanges heat with the air conveyed from the indoor to the indoor heat exchange cavity to adjust the temperature of the indoor air; when the refrigerant flows to the condenser, it mainly exchanges heat with the air conveyed into the outdoor heat exchange cavity to achieve the cooling of the refrigerant, and the air after heat exchange is discharged to the outside. A mobile air conditioner needs to be connected to an outdoor exhaust duct during use.

[0003] However, the existing exhaust ducts often use a rotating method to cooperate with the joints. The assembly process between the exhaust duct and the structure during assembly is relatively complex, which affects the use performance of the exhaust duct and thus affects the user's experience of using the air conditioner. At the same time, the relatively complex structure is not convenient for subsequent maintenance, reduces the service life, and increases the use cost of the air conditioner. Summary of the Utility Model

[0004] This application aims to solve the above technical problems, that is, to solve the problem of the complex connection structure of the outdoor exhaust duct in a mobile air conditioner.

[0005] This application provides a mobile air conditioner, including: a housing, an outdoor heat exchange cavity is formed inside, and the housing includes a rear shell; an outdoor air outlet, corresponding to the outdoor heat exchange cavity, is opened on the rear shell, and the outdoor air outlet is configured to connect to an outdoor exhaust duct; an installation clamping ring, arranged around the outdoor air outlet and integrally formed with the rear shell, the installation clamping ring extends in a direction away from the rear shell, and the installation clamping ring is configured to be able to be sleeved on the outer periphery of the outdoor exhaust duct.

[0006] In the case of adopting the above technical solution, by integrally forming an installation clamping ring on the rear shell, the structure can be simplified and the installation difficulty can be reduced, and the installation clamping ring integrally formed with the rear shell has high structural strength and can be used for a long time, thus avoiding the loosening or fracture of the installation clamping ring caused by multiple disassembly and assembly of the outdoor exhaust duct, and having a long service life; and through the provided installation clamping ring, sleeving it on the outer periphery of the outdoor exhaust duct can achieve stable clamping installation of the outdoor exhaust duct.

[0007] In the optional implementation of the above-mentioned mobile air conditioner, one end of the installation clamping ring is connected to the rear shell, and the other end of the installation clamping ring inclines inwards towards the axis.

[0008] In this way, the other end of the installation clamping ring, that is, the end for clamping the outdoor air duct, has a tendency to tighten inwards, thereby improving the clamping effect on the outdoor air duct.

[0009] In the optional implementation of the above-mentioned mobile air conditioner, a plurality of buckles are arranged at intervals along the circumferential direction of the inner wall surface of the installation clamping ring, and the buckles are used for clamping the outdoor air duct.

[0010] In this way, through the clamping of the outdoor air duct by the buckles arranged on the inner wall surface of the installation clamping ring, the detachable installation of the outdoor air duct can be realized, which is convenient for disassembly, installation or replacement.

[0011] In the optional implementation of the above-mentioned mobile air conditioner, the buckle includes: a connecting arm, including a free end and a fixed end arranged oppositely, and the fixed end is connected to the installation clamping ring; a hook, fixedly arranged at the free end of the connecting arm, and the hook extends towards the axis of the installation clamping ring.

[0012] In this way, the end of the outdoor air duct can be clamped between the gap between the hook and the rear shell, thereby ensuring the stability of the outdoor air duct after installation.

[0013] In the optional implementation of the above-mentioned mobile air conditioner, a guiding inclined surface extending obliquely towards the rear shell is provided on the end surface of the hook facing away from the rear shell.

[0014] In this way, through the arrangement of the guiding inclined surface, it is beneficial to the installation of the outdoor air duct. When installing the outdoor air duct, push the end of the outdoor air duct, so that it can move along the guiding inclined surface towards the direction of the rear shell, and then slide into the gap between the hook and the rear shell, reducing the force application and improving the installation efficiency.

[0015] In the optional implementation of the above-mentioned mobile air conditioner, gaps are provided on both sides of each buckle, and the bottom end of the gap has a distance from the rear shell.

[0016] By setting the gaps and making the bottom end of the gaps have a distance from the rear shell, the stress distribution on both sides of the buckle can be changed, enabling the buckle to have a certain elastic deformation, improving the elasticity and adaptability of the buckle, facilitating the clamping of the outdoor air duct by the buckle, and facilitating the disassembly of the outdoor air duct. In the optional implementation of the above-mentioned mobile air conditioner, the extending width range of the gap along the circumferential direction of the installation clamping ring is 1 mm to 4 mm.

[0017] Since the outdoor air duct may need to be installed or disassembled frequently, when the buckle needs to have sufficient elasticity, the stability of the connection also needs to be ensured. By making the extension width range of the notch along the circumference of the installation collar be 1 mm to 4 mm, it is possible to avoid the problem that the notch is too large, resulting in a reduction in the strength of the buckle and preventing the buckle from breaking or failing when stressed.

[0018] In an alternative embodiment of the above-mentioned mobile air conditioner, the mobile air conditioner further includes: an air outlet guard net, which is arranged at the outdoor air outlet, and the air outlet guard net is integrally formed with the rear shell.

[0019] By integrally forming the air outlet guard net on the rear shell, the number of components can be reduced, the assembly process can be simplified, and the installation difficulty can be reduced. Moreover, the air outlet guard net integrally formed with the rear shell has high structural strength and can be used for a long time, thus avoiding the problem of the air outlet guard net shaking and reducing the airflow noise.

[0020] In an alternative embodiment of the above-mentioned mobile air conditioner, the air outlet guard net includes: a plurality of annular grille bars, which are arranged coaxially with the outdoor air outlet and are spaced apart along the radial direction of the outdoor air outlet; a plurality of connecting grille bars, which are arranged at intervals around the circumference of the outdoor air outlet and extend along the radial direction of the outdoor air outlet, and the connecting grille bars can be sequentially connected to the plurality of annular grille bars.

[0021] By providing the annular grille bars and the connecting grille bars, the outdoor air outlet can be divided into a plurality of small sub-air outlets, thereby dispersing the air outlet airflow, reducing the flow rate, reducing the noise generated by the airflow, and improving the comfort of the user when using the mobile air conditioner. In addition, such an arrangement can also reduce the entry of mice and the like outdoors into the outdoor heat exchange chamber through the outdoor air inlet, preventing them from damaging the electrical components inside the outdoor heat exchange chamber.

[0022] In an alternative embodiment of the above-mentioned mobile air conditioner, the spacing range between adjacent annular grille bars is 3 to 18 mm.

[0023] Setting the spacing range between adjacent annular grille bars to be 3 to 18 mm can improve safety while ensuring the air volume. Specifically, when the spacing between adjacent annular grille bars is too large, foreign objects such as mice can enter the outdoor heat exchange chamber, causing potential safety hazards; if the spacing between adjacent annular grille bars is too small, a large air resistance will be generated when the air flow passes through, reducing the air volume.

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

[0038] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" 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 or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific situations.

[0039] Combined with Figures 1 to 5 As shown, this application provides a mobile air conditioner, which includes a housing 100, an outdoor air outlet 101, an air outlet protection net 200, and a mounting snap ring 500. An outdoor heat exchange chamber 110 is formed inside the housing 100. The housing 100 includes a rear shell 130. The outdoor air outlet 101 is opened on the rear shell 130 corresponding to the outdoor heat exchange chamber 110, and the outdoor air outlet 101 is configured to connect to an outdoor air duct 102. The air outlet protection net 200 is disposed at the outdoor air outlet 101, and the air outlet protection net 200 is integrally formed with the rear shell 130. The mounting snap ring 500 is fixedly arranged around the outdoor air outlet 101, and the mounting snap ring 500 extends in a direction away from the rear shell 130 and is configured to be able to sleeved on the outer periphery of the outdoor air duct 102.

[0040] Optionally, a cavity is defined inside the housing 100, and a partition 300 is provided in the cavity. The partition 300 can divide the cavity inside the housing 100 into an indoor heat exchange chamber 120 and an outdoor heat exchange chamber 110 that are distributed up and down and are independent of each other. Among them, an indoor heat exchanger 410 and an indoor fan assembly 420 are provided in the indoor heat exchange chamber 120, and corresponding indoor air inlets and indoor air outlets are provided on the housing 100. At the same time, an outdoor heat exchanger, an outdoor fan assembly 440, and a compressor are provided in the outdoor heat exchange chamber 110, and corresponding outdoor air inlets and the outdoor air outlet 101 are provided on the housing 100. The compressor, the indoor heat exchanger, and the outdoor heat exchanger are connected through a refrigerant pipeline so that the refrigerant can form a cycle.

[0041] The indoor air flow is driven by the indoor fan assembly 420 to enter the indoor heat exchange chamber through the indoor air inlet to exchange heat with the refrigerant in the indoor heat exchanger 410. The heat-exchanged air flow flows into the indoor environment through the indoor air outlet to achieve the adjustment of the indoor environment. At the same time, outdoor air can be introduced through the outdoor air inlet to exchange heat with the refrigerant in the outdoor heat exchanger, thereby ensuring the normal operation of the outdoor heat exchanger to ensure the circulation of the refrigerant among the indoor heat exchanger 410, the outdoor heat exchanger, and the compressor.

[0042] Specifically, the outer shell 100 includes a front shell 140, a rear shell 130, and a bottom plate. After the front shell 140 and the rear shell 130 are fastened to each other, a cavity is jointly defined with the bottom plate. A room outlet 101 corresponding to the outdoor heat exchange cavity 110 is provided on the rear shell 130. Further, in order to discharge the air flow, an outdoor air duct 102 is usually installed at the room outlet 101 and the outdoor air duct 102 is connected to the outside. In order to prevent foreign objects such as mice outdoors from entering the outdoor heat exchange cavity 110 through the room outlet 101 at this time, a blocking object needs to be installed at the room outlet 101 while not affecting the discharge of the air flow.

[0043] Further, an integrally presented mounting snap ring 500 is provided at the room outlet 101. By sleeving it on the outer periphery of one end of the outdoor air duct 102, the installation of the outdoor air duct 102 can be realized, so as to discharge the heat-exchanged air flow to the outside.

[0044] Optionally, the outdoor air duct 102 can be selected as a corrugated pipe to facilitate the storage and placement after disassembly while ensuring the strength of the outdoor air duct 102.

[0045] Optionally, the end of the outdoor air duct 102 abuts against the rear shell 130 to prevent air leakage. Further, a sealing ring is provided at the connection between the inner wall surface of the mounting snap ring 500 and the rear shell 130, and the end of the outdoor air duct 102 abuts against the sealing ring to achieve the sealing during the installation of the outdoor air duct 102. Optionally, the sealing ring is a rubber sealing ring, which has a low cost and is easy to install.

[0046] Alternatively, no sealing ring is provided at the connection between the inner wall surface of the mounting snap ring 500 and the rear shell 130.

[0047] Optionally, the end of the outdoor air duct 102 is sleeved with an end head, and the end head is made of a rigid material, such as an injection molded part, to increase the hardness of this end of the outdoor air duct 102 for the convenience of installing the outdoor air duct 102.

[0048] In the case of adopting the above technical solution, by integrally forming a mounting snap ring on the rear shell, the structure can be simplified and the installation difficulty can be reduced. Moreover, the mounting snap ring integrally formed with the rear shell has high structural strength and can be used for a long time, thus avoiding the loosening or breakage of the mounting snap ring caused by multiple disassembly and assembly of the outdoor air duct, and having a long service life; and through the provided mounting snap ring, by sleeving it on the outer periphery of the outdoor air duct, stable clamping installation of the outdoor air duct can be realized.

[0049] In the optional implementation of the above mobile air conditioner, one end of the mounting snap ring 500 is connected to the rear shell 130, and the other end of the mounting snap ring 500 is inclined inward toward the axis.

[0050] In this way, the other end of the mounting snap ring 500, that is, one end of the outdoor air duct 102 of the clamping chamber, has a tendency to tighten inward, so as to improve the clamping effect on the outdoor air duct 102.

[0051] Alternatively, the mounting snap ring 500 extends along the axial direction.

[0052] In an alternative embodiment of the above-mentioned mobile air conditioner, a plurality of buckles 510 are arranged at intervals along the circumferential direction on the inner wall surface of the mounting snap ring 500, and the buckles 510 are used to clamp the outdoor air duct 102.

[0053] In this way, through the clamping of the outdoor air duct 102 by the buckles 510 provided on the inner wall surface of the mounting snap ring 500, the detachable installation of the outdoor air duct 102 can be realized, which is convenient for disassembly, assembly or replacement.

[0054] Optionally, the buckle 510 is integrally formed with the mounting snap ring 500, which has high stability and low cost.

[0055] Optionally, the plurality of buckles 510 are arranged at equal intervals to ensure uniform stress on the mounting snap ring 500.

[0056] Alternatively, on the inner wall surface of the other end of the mounting snap ring 500, there is provided an annular flange extending along its circumferential direction and extending towards the axial direction. By clamping the end of the outdoor air duct 102 between the flange and the rear shell 130, the installation of the outdoor air duct 102 is realized.

[0057] In an alternative embodiment of the above-mentioned mobile air conditioner, the buckle 510 includes a connecting arm 511 and a hook 512. The connecting arm 511 includes a free end and a fixed end arranged oppositely, and the fixed end is connected to the mounting snap ring 500; the hook 512 is fixedly arranged at the free end of the connecting arm 511, and the hook 512 extends towards the axis of the mounting snap ring 500.

[0058] In this way, the end of the outdoor air duct 102 can be clamped between the gap between the hook 512 and the rear shell 130, so as to ensure the stability of the outdoor air duct 102 after installation.

[0059] Optionally, a groove is formed between the end head provided at the end of the outdoor air duct 102 and the outer wall surface of the outdoor air duct 102. In this way, the hook 512 abuts at least partially against the side wall of the end head facing the hook 512, and the hook 512 abuts against the outer wall surface of the outdoor air duct 102, so as to realize the stable clamping of the outdoor air duct 102.

[0060] Alternatively, the buckle 510 only includes the hook 512, and the hook 512 is arranged on the inner wall surface of the mounting snap ring 500, or the hook 512 is arranged at the end of the mounting snap ring 500 away from the rear shell 130.

[0061] In the alternative embodiment of the above-mentioned mobile air conditioner, a guiding inclined surface 5121 extending obliquely towards the rear shell 130 is provided on the end surface of the hook 512 facing away from the rear shell 130.

[0062] Thus, through the arrangement of the guiding inclined surface 5121, the movement direction of the end of the outdoor air duct 102 can be changed to achieve the rapid installation of the outdoor air duct 102. Specifically, when installing the outdoor air duct 102, the end of the outdoor air duct 102 is pushed so that it can move along the guiding inclined surface 5121 towards the rear shell 130, and thus slide into the gap between the hook 512 and the rear shell 130, reducing the application force and improving the installation efficiency.

[0063] Alternatively, according to actual requirements, a guiding inclined surface 5121 extending obliquely towards the rear shell 130 may not be provided on the end surface of the hook 512 facing away from the rear shell 130.

[0064] In the alternative embodiment of the above-mentioned mobile air conditioner, notches 520 are provided on both sides of each buckle 510, and there is a distance between the bottom end of the notch 520 and the rear shell 130.

[0065] By providing the notches 520 and having a distance between the bottom end of the notch 520 and the rear shell 130, the stress distribution on both sides of the buckle 510 can be changed, enabling the buckle 510 to have a certain elastic deformation, improving the elasticity and adaptability of the buckle 510, facilitating the clamping of the outdoor air duct 102 by the buckle, and facilitating the disassembly of the outdoor air duct 102.

[0066] It can also be said that a plurality of grooves are provided along the circumferential direction of the mounting snap ring 500, and the buckle 510 is disposed in the groove. The hook 512 of the buckle 510 is disposed at the bottom end facing away from the groove.

[0067] Alternatively, the notches 520 may not be provided.

[0068] In the alternative embodiment of the above-mentioned mobile air conditioner, the extending width range of the notch 520 along the circumferential direction of the mounting snap ring 500 is 1 mm to 4 mm.

[0069] Since the outdoor air duct 102 may need to be installed or disassembled frequently, when the buckle 510 requires sufficient elasticity, the connection stability also needs to be ensured. By making the extending width range of the notch 520 along the circumferential direction of the mounting snap ring 500 be 1 mm to 4 mm, it is possible to prevent the notch 520 from being too large, resulting in a reduction in the strength of the buckle 510, and further avoiding problems such as the buckle 510 breaking or failing when stressed.

[0070] Preferably, the width of the notch 520 is 1.5 mm, 2 mm, 2.5 mm, etc.

[0071] In the alternative implementation of the above-mentioned mobile air conditioner, the mobile air conditioner further includes an air outlet protection net 200. The air outlet protection net 200 is disposed at the outdoor air outlet 101, and the air outlet protection net 200 is integrally formed with the rear shell 130.

[0072] By integrally forming the air outlet protection net 200 on the rear shell 130, the number of components can be reduced, the assembly process can be reduced, and the installation difficulty can be lowered. Moreover, the air outlet protection net 200 integrally formed with the rear shell 130 has high structural strength and can be used for a long time, thereby avoiding the problem of the air outlet protection net 200 shaking and reducing the air flow noise.

[0073] Alternatively, the air outlet protection net 200 can be connected to the rear shell 130 by means of gluing, snap connection, or screw connection.

[0074] In the alternative implementation of the above-mentioned mobile air conditioner, the air outlet protection net 200 includes annular grille bars 210 and connecting grille bars 220. A plurality of annular grille bars 210 are arranged coaxially with the outdoor air outlet 101 and are arranged at intervals along the radial direction of the outdoor air outlet 101; a plurality of connecting grille bars 220 are arranged at intervals around the circumference of the outdoor air outlet and extend along the radial direction of the outdoor air outlet 101, and the connecting grille bars can be sequentially connected to the plurality of annular grille bars.

[0075] By providing the connecting grille bars 220, the connection strength of the plurality of annular grille bars 210 can be improved. By providing the annular grille bars 210 and the connecting grille bars 220, the outdoor air outlet 101 can be divided into a plurality of small sub-air outlets, thereby dispersing the air flow, reducing the flow rate, reducing the noise generated by the air flow, and improving the comfort of the user when using the mobile air conditioner. In addition, with such an arrangement, it is also possible to reduce the entry of mice and the like outdoors into the outdoor heat exchange chamber 110 through the outdoor air outlet 101 and prevent them from damaging the electrical components inside the outdoor heat exchange chamber 110.

[0076] Alternatively, grille bars extending only in the first direction and the second direction, where the first direction and the second direction intersect each other, can be provided. In this way, the outdoor air outlet 101 can also be divided into a plurality of sub-air outlets.

[0077] In the alternative implementation of the above-mentioned mobile air conditioner, the distance between adjacent annular grille bars 210 ranges from 3 to 18 mm.

[0078] Setting the distance between adjacent annular grille bars 210 to range from 3 to 18 mm can improve safety while ensuring the air volume. Specifically, when the distance between adjacent annular grille bars 210 is too large, foreign objects such as mice may enter the outdoor heat exchange chamber, posing a safety hazard; if the distance between adjacent annular grille bars 210 is too small, a large wind resistance will be generated when the air flow passes through, reducing the air volume.

[0079] Preferably, the spacing between adjacent annular grid bars 210 can be 5 mm, 7 mm, 8 mm, etc.

However, it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific embodiments.
