Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically providing a portable air conditioner. Background Technology

[0002] Currently, both wall-mounted and floor-standing air conditioners require fixed installation in a limited location and cannot be moved. Therefore, portable air conditioners have emerged. A portable air conditioner mainly consists of a casing, an indoor airflow assembly, and an outdoor airflow assembly. Both the indoor and outdoor airflow assemblies are housed within the casing. The casing has indoor air inlets and outlets corresponding to the indoor airflow assembly, and similarly, outdoor air inlets and outlets corresponding to the outdoor airflow assembly. Due to their small size, portable air conditioners can be moved to different locations or rooms to regulate the air temperature in those locations or rooms.

[0003] In portable air conditioners of this technology, the indoor and outdoor heat exchangers are housed in two independent heat exchange chambers within the same casing. To improve heat exchange capacity, the volume of the indoor heat exchanger is typically increased, which in turn increases the overall size of the portable air conditioner. However, for ease of portability, the size of the portable air conditioner should not be too large. Therefore, the volumes of the indoor and outdoor heat exchangers are correspondingly smaller, resulting in insufficient heat exchange capacity. Utility Model Content

[0004] The present invention aims to solve the above-mentioned technical problem, namely, to solve the problem of low heat exchange capacity of portable air conditioners.

[0005] This utility model provides a portable air conditioner, comprising: a casing, which internally defines an indoor heat exchange chamber, wherein a top cover plate of the casing is provided with an indoor air outlet of the indoor heat exchange chamber, and the axis of the indoor air outlet coincides with the central axis of the top cover plate; an indoor heat exchanger disposed in the indoor heat exchange chamber, comprising at least a first heat exchange section, a second heat exchange section, and a third heat exchange section arranged in a bent manner, wherein a first side plate, a back plate, and a second side plate of the casing are respectively provided with a first indoor air inlet, a second indoor air inlet, and a third indoor air inlet corresponding to the first heat exchange section, the second heat exchange section, and the third heat exchange section; and an indoor fan, at least partially disposed within the space surrounding the indoor heat exchanger, wherein the rotation axis of the indoor fan coincides with the axis of the indoor air outlet.

[0006] By employing the above technical solution, and by respectively providing a first indoor air inlet, a second indoor air inlet, and a third indoor air inlet on the first side plate, back plate, and second side plate of the casing corresponding to the first, second, and third heat exchange sections, the air intake area of ​​the portable air conditioner can be increased, thereby ensuring the air volume. The air entering the indoor heat exchange chamber exchanges heat with the indoor heat exchanger to regulate the air temperature, etc. Thus, the portable air conditioner, while having a small size, possesses high heat exchange capacity and heat exchange efficiency, ensuring effective indoor air conditioning. Simultaneously, the axis of the indoor air outlet, the central axis of the top cover, and the rotation axis of the indoor fan coincide. This arrangement not only optimizes the air duct layout within the casing to reduce the size of the portable air conditioner but also reduces airflow turbulence, improves airflow uniformity, reduces noise, and enhances the comfort of the portable air conditioner's airflow.

[0007] In the optional implementation of the above-mentioned portable air conditioner, the first indoor air inlet is composed of a plurality of first sub-air inlets opened on the first side panel and arranged at intervals; and / or, the second indoor air inlet is composed of a plurality of second sub-air inlets opened on the back panel and arranged at intervals; and / or the third indoor air inlet is composed of a plurality of third sub-air inlets opened on the second side panel and arranged at intervals.

[0008] This design, while ensuring the structural strength and stability of the casing, improves the uniformity of the airflow into the indoor heat exchange chamber of the portable air conditioner, thereby enhancing the heat exchange effect between the air entering the indoor heat exchange chamber and the indoor heat exchanger.

[0016] The outdoor duct assembly divides the inner cavity of the unit into an indoor heat exchange chamber and an outdoor heat exchange chamber. By fixing the motor assembly to the outdoor duct assembly and at least partially located in the indoor heat exchange chamber, the space of the unit can be fully utilized. One motor assembly drives both the indoor fan and the outdoor fan, which can further reduce the number of components in the portable air conditioner and reduce the space occupied, improve space utilization, and reduce the size of the portable air conditioner.

[0017] In an optional embodiment of the above-mentioned portable air conditioner, the outdoor air duct assembly includes: an upper air duct plate, arranged facing the indoor heat exchange chamber, and the upper air duct plate forming a support structure and a water receiving structure for the indoor heat exchanger; a lower air duct plate, arranged opposite to the upper air duct plate, and provided with a fan inlet communicating with the outdoor heat exchange chamber; and a volute, fixed to the lower air duct plate, and together with the upper air duct plate and the lower air duct plate, enclosing the fan chamber, and the volute having a fan outlet facing the back panel.

[0018] The coordination between the upper and lower air duct plates and the volute casing optimizes the airflow path through the outdoor heat exchange chamber. Simultaneously, the upper air duct plate integrates the support structure and water collection structure for the indoor heat exchanger, reducing the number of independent components and improving space utilization and the structural utilization of the outdoor air duct assembly.

[0022] By combining the installation steps with the installation ribs, the installation efficiency of outdoor air duct components can be improved. At the same time, it can help reduce the gap at the joint between the outdoor air duct components and the back panel, thereby reducing air leakage and the generation of airflow noise.

[0023] In an optional embodiment of the above-mentioned portable air conditioner, the outdoor cavity inlet and the outdoor cavity outlet are respectively provided with a first grille and a second grille, and the first grille and / or the second grille are integrally formed with the back panel.

[0046] Optionally, the housing 100 includes at least a top cover plate 110, a first side plate 120, a back plate 130, a second side plate 140, a front panel, and a chassis. The housing 100 internally defines two independent indoor heat exchange chambers 101 and 102. In this design, the indoor heat exchange chambers 101 and 102 are arranged vertically. Alternatively, the indoor heat exchange chambers 101 and 102 are arranged adjacent to each other horizontally. Optionally, the top cover plate 110 is positioned corresponding to the indoor heat exchange chamber 101, and has an indoor air outlet 111 for air to exit from the indoor heat exchange chamber 101. Optionally, the indoor air outlet 111 coincides with the central axis of the top cover plate 110, i.e., the indoor air outlet 111 is located at the center of the top cover plate 110.

[0047] Optionally, an indoor heat exchanger 200 is provided in the indoor heat exchange chamber 101, and the indoor heat exchanger 200 includes at least a first heat exchange section 210, a second heat exchange section 220, and a third heat exchange section 230 arranged in a bent manner. In this embodiment, the indoor heat exchanger 200 is constructed in a U-shape. The first heat exchange section 210, the second heat exchange section 220, and the third heat exchange section 230 together enclose a recessed space, in which at least a portion of the indoor fan 310 can be arranged to form a protection for the indoor heat exchanger 200 and facilitate the driving of the indoor fan 310 for the indoor air, so that the indoor air enters the indoor heat exchange chamber 101 through one or more of the first indoor air inlet 121, the second indoor air inlet 131, and the third indoor air inlet 141.

[0048] Optionally, the housing 100 includes a top cover 110, a front cover, a rear cover, and a chassis. The rear cover includes a first side panel 120, a back panel 130, and a second side panel 140.

[0049] Optionally, the front cover and the rear cover are integrally molded to improve structural stability and increase installation efficiency.

[0050] Optionally, to match the heat exchange capacity of the indoor heat exchanger 200, a first indoor air inlet 121, a second indoor air inlet 131, and a third indoor air inlet 141 are respectively provided on the first side plate 120, the back plate 130, and the second side plate 140. Optionally, to ensure the structural strength and stability of the casing 100, the first indoor air inlet 121, the second indoor air inlet 131, and the third indoor air inlet 141 are independent of each other.

[0051] Optionally, the first heat exchange section 210, the second heat exchange section 220, and the third heat exchange section 230 are connected end to end in sequence to form an indoor heat exchanger 200 that shares a common set of heat exchange pipes.

[0052] Alternatively, the first heat exchange section 210, the second heat exchange section 220, and the third heat exchange section 230 can be operated independently, i.e., connected in parallel. To reduce structural complexity and cost, the three heat exchange sections share a single distributor and collector, and each has a control valve at its respective refrigerant inlet. Thus, the operation of one or more of the first heat exchange section 210, the second heat exchange section 220, and the third heat exchange section 230 can be controlled via the control valves according to the actual cooling capacity requirements. This improves the temperature uniformity and stability during the operation of the portable air conditioner.

[0055] Optionally, the indoor fan 310 is at least partially arranged within the space surrounding the indoor heat exchanger 200. The rotation axis of the indoor fan 310 is aligned with the axis of the indoor air outlet 111.

[0057] By employing the above technical solution, and by respectively providing a first indoor air inlet, a second indoor air inlet, and a third indoor air inlet on the first side plate, back plate, and second side plate of the casing corresponding to the first, second, and third heat exchange sections, the air intake area of ​​the portable air conditioner can be increased, thereby ensuring the air volume. The air entering the indoor heat exchange chamber exchanges heat with the indoor heat exchanger to regulate the air temperature, etc. Thus, the portable air conditioner, while having a small size, possesses high heat exchange capacity and heat exchange efficiency, ensuring effective indoor air conditioning. Simultaneously, the axis of the indoor air outlet, the central axis of the top cover, and the rotation axis of the indoor fan coincide. This arrangement not only optimizes the air duct layout within the casing to reduce the size of the portable air conditioner but also reduces airflow turbulence, improves airflow uniformity, reduces noise, and enhances the comfort of the portable air conditioner's airflow.

[0058] In the optional implementation of the above-mentioned portable air conditioner, the first indoor air inlet 121 is composed of a plurality of first sub-air inlets opened on the first side panel 120 and arranged at intervals; and / or the second indoor air inlet 131 is composed of a plurality of second sub-air inlets opened on the back panel 130 and arranged at intervals; and / or the third indoor air inlet 141 is composed of a plurality of third sub-air inlets opened on the second side panel 140 and arranged at intervals.

[0072] By setting the outer periphery of the indoor air outlet grille 113 to overlap the upper surface of the top cover plate 110, air leakage at this connection point can be minimized, and the assembly gap between the top cover plate 110 and the indoor air outlet grille 113 can be concealed, improving aesthetics. Simultaneously, the cooperation of the slot 1141 and the positioning rod 1142 enables quick positioning and installation of the indoor air outlet grille 113.

[0077] Optionally, the horizontal step plate 1121 is provided with a mounting slot 1151, and the inner wall surface of the outer periphery of the indoor air outlet grille 113 is provided with a mounting buckle 1152. Through the cooperation of the mounting slot 1151 and the mounting buckle 1152, a stable connection between the top cover plate 110 and the indoor air outlet grille 113 is achieved.

[0078] In the optional embodiment of the above-mentioned portable air conditioner, the inner surface of the indoor air outlet grille 113 is provided with a limiting rib 1131. The limiting rib 1131 is arranged circumferentially around the outer periphery of the indoor air outlet grille 113 and abuts against the vertical step plate 1122 of the step portion 112.

[0079] By setting the limiting rib 1131 to abut against the vertical step plate 1122, the sealing of the connection between the indoor air outlet grille 113 and the top cover plate 110 can be further achieved, reducing air leakage and noise.

[0080] In the optional implementation of the above-mentioned portable air conditioner, a duct cover 240 is also included. The duct cover 240 is fixed to the top of the indoor heat exchanger 200 and abuts against the casing 100. A vent 241 is provided on the duct cover 240, and the indoor fan 310 passes through the vent 241 and exits the duct cover 240.

[0081] The duct cover 240 is designed to ensure that air can exchange heat with the indoor heat exchanger 200 before flowing to the indoor air outlet 111, thereby ensuring the temperature regulation effect.

[0082] Optionally, the portable air conditioner also includes a deflector ring 116. The deflector ring 116 is detachably disposed between the top cover plate 110 and the duct cover plate 240. The shape and profile of one end of the deflector ring 116 matches the shape of the indoor air outlet 111, and the shape and profile of the other end matches the shape of the vent 241.

[0083] By setting the airflow guide ring 116, the air driven by the indoor fan 310 can be guided to flow towards the indoor air outlet 111, making the air flow more concentrated or more evenly through the indoor air outlet 111, thereby improving air supply efficiency. In addition, the airflow guide ring 116 can also serve as a structural support, enhancing the connection strength between the duct cover 240 and the top cover 110, and preventing deformation or vibration.

[0084] Optionally, the flow guide ring 116 is snapped into the air duct cover 240. Specifically, one of the connecting buckle 1161 and the connecting groove 243 is provided on the outer wall surface of the flow guide ring 116, and the other is provided on the air duct cover 240.

[0095] In an optional embodiment of the portable air conditioner described above, the outdoor air duct assembly 400 includes an upper air duct plate 410, a lower air duct plate 420, and a volute 430. The upper air duct plate 410 is arranged facing the indoor heat exchange chamber 101, and forms a support structure and a water receiving structure for the indoor heat exchanger 200. The lower air duct plate 420 is arranged opposite to the upper air duct plate 410 and is provided with a fan inlet 421 communicating with the outdoor heat exchange chamber 102. The volute 430 is fixed to the lower air duct plate 420 and, together with the upper air duct plate 410 and the lower air duct plate 420, encloses the fan chamber 401. A fan outlet 431 facing the back panel 130 is formed on the volute 430.

[0096] The cooperation between the upper air duct plate 410, the lower air duct plate 420, and the volute 430 helps to optimize the airflow path through the outdoor heat exchange chamber 102. At the same time, the upper air duct plate 410 integrates the support structure and water receiving structure of the indoor heat exchanger 200, which helps to reduce the number of independent components and improve space utilization and the structural utilization of the outdoor air duct assembly 400.

[0097] Optionally, the upper surface of the upper air duct plate 410 facing the indoor heat exchange chamber 101 is provided with support ribs 411. The shape of the support ribs 411 matches the shape of the indoor heat exchanger 200, and at least two support ribs 411 are provided. The two support ribs 411 constitute the support structure of the indoor heat exchanger 200. The space between the two support ribs 411 and between the support ribs 411 and the upwardly extending sidewall of the upper air duct plate 410 is a water receiving space. Optionally, drainage ribs are provided between the support ribs 411, and water passage gaps are provided between adjacent drainage ribs and between the drainage ribs and the support ribs.

[0098] Optionally, the motor assembly 500 is fixed to the upper air duct plate 410 to simultaneously drive the indoor fan 310 and the outdoor fan 320.

[0099] Optionally, the volute 430 and the lower air duct plate 420 are integrally formed. Alternatively, the volute 430 and the upper air duct plate 410 are integrally formed.

[0100] Alternatively, the volute 430 includes an upper volute fixed to the upper air duct plate 410 and a lower volute fixed to the lower air duct plate 420.

[0101] In the above-mentioned optional implementation of the portable air conditioner, the first heat exchange section 210 is provided with a first end plate 251 on the side opposite to the second heat exchange section 220, and the third heat exchange section 230 is provided with a second end plate 252 on the side opposite to the second heat exchange section 220; the upper end of the first end plate 251 and the upper end of the second end plate 252 are respectively detachably connected to the air duct cover plate 240, and the lower end of the first end plate 251 and the lower end of the second end plate 252 are respectively detachably connected to the upper air duct plate 410.

[0102] By connecting the first end plate 251 and the second end plate 252 to the duct cover plate 240 and the upper duct plate 410 respectively, it is beneficial to improve the stability of the indoor heat exchanger 200, avoid the shaking of the indoor heat exchanger 200, and reduce noise.

[0103] Optionally, the first end plate 251 and the second end plate 252 are configured to abut against the inner wall surface of the housing 100.

[0104] Alternatively, a first baffle is connected between the first end plate 251 and the housing 100, and a second baffle is connected between the second end plate 252 and the housing 100, so as to avoid the waste of energy caused by air flowing directly to the indoor fan 310 without exchanging heat with the indoor heat exchanger 200 and mixing with the heat-exchanged air, thereby improving energy utilization.

[0105] In the optional embodiment of the above-mentioned portable air conditioner, the back panel 130 has an outdoor cavity inlet 132 and an outdoor cavity outlet 133.

At least the first side plate and the second side of the outdoor cavity outlet 133 are respectively provided with vertically extending mounting ribs 1331, and the fan outlet 431 is provided with mounting steps 4311 that cooperate with the mounting ribs 1331.

[0106] The installation of the step 4311 and the mounting rib 1331 together improves the installation efficiency of the outdoor air duct assembly 400 and reduces the gap at the joint between the outdoor air duct assembly 400 and the back panel 130, thereby reducing air leakage and airflow noise.

[0107] Optionally, the mounting rib 1331 is arranged to extend circumferentially around the outdoor cavity outlet 133.

[0108] Alternatively, an installation groove is provided at the fan outlet 431, and the installation rib 1331 can be inserted into the installation groove.

[0109] In the optional implementation of the above-mentioned portable air conditioner, the outdoor cavity inlet 132 and the outdoor cavity outlet 133 are respectively provided with a first grille 1321 and a second grille 1332, and the first grille 1321 and / or the second grille 1332 are integrally formed with the back panel 130.

[0110] The outdoor cavity inlet 132 and the outdoor cavity outlet 133 are respectively provided with a first grille 1321 and a second grille 1332, which helps to prevent foreign objects from entering the outdoor heat exchange cavity 102. Since the first grille 1321 and / or the second grille 1332 are integrally formed with the back plate 130, it helps to improve the structural strength of the back plate 130 and extend its service life.

[0111] Alternatively, the first grille 1321 and the second grille 1332 are detachably connected to the back plate 130. For example, they can be connected by snap-fit ​​or plug-in methods to facilitate cleaning of the outdoor heat exchange chamber 102 or replacement and maintenance of small internal components.
