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, and an indoor air outlet corresponding to the indoor heat exchange chamber is provided on the top cover of the casing; a first indoor heat exchanger disposed in the indoor heat exchange chamber, including a first heat exchange section and a second heat exchange section arranged in a bent manner, wherein a first indoor air inlet and a second indoor air inlet are respectively provided on the casing corresponding to the first heat exchange section and the second heat exchange section; a second indoor heat exchanger, including a third heat exchange section and a fourth heat exchange section arranged in a bent manner, and corresponding to the first heat exchange section and the second heat exchange section end to end to jointly enclose an indoor air duct space; wherein a third indoor air inlet and a fourth indoor air inlet are respectively provided on the casing corresponding to the third heat exchange section and the fourth heat exchange section; and an indoor fan, which is arranged in the indoor air duct space or above the indoor air duct space corresponding to the indoor air outlet.

[0006] By employing the above technical solution, the air intake area of ​​the portable air conditioner can be increased by setting a first indoor air inlet, a second indoor air inlet, a third indoor air inlet, and a fourth indoor air inlet on the casing, corresponding to the first and second indoor heat exchangers, thereby ensuring sufficient airflow. Simultaneously, the air entering the indoor heat exchange chamber exchanges heat with the corresponding first, second, third, and fourth heat exchange sections. This allows the portable air conditioner to have a small size while possessing high heat exchange capacity and efficiency, thus ensuring effective indoor air conditioning. Furthermore, the air after heat exchange flows back into the indoor environment through the indoor air outlet located on the top cover, preventing direct airflow onto the user and improving comfort.

[0007] In an optional embodiment of the above-mentioned portable air conditioner, the indoor fan and the indoor air outlet are coaxially arranged along the vertical central axis of the indoor air duct space; wherein, the vertical central axis of the indoor air duct space coincides with the vertical central axis of the indoor heat exchange chamber.

[0008] By arranging the indoor fan, indoor air outlet, and indoor air duct space coaxially, it is possible to effectively reduce wind resistance and improve air flow efficiency; on the other hand, it can make the structure of the portable air conditioner more compact and save space.

[0009] In an optional embodiment of the above-mentioned portable air conditioner, the housing has a front cover and a rear cover that are connected to each other; the back panel of the rear cover is provided with the first indoor air inlet; the first left side panel of the rear cover and / or the second left side panel of the front cover are provided with the second indoor air inlet; the front panel of the front cover is provided with the third indoor air inlet; the second right side panel of the front cover and / or the first right side panel of the rear cover are provided with the fourth indoor air inlet; wherein, the first left side panel is correspondingly connected to the second left side panel; the first right side panel is correspondingly connected to the second right side panel.

[0010] By configuring the casing as a front cover and a rear cover that are connected to each other, it is convenient for the installation and maintenance of the casing; the back panel is provided with a first indoor air inlet and the front panel is provided with a third indoor air inlet to ensure the heat exchange capacity of the first heat exchange section and the third heat exchange section; furthermore, the first right side plate of the rear cover and / or the second right side plate of the front cover are provided with a second indoor air inlet, and the second left side plate of the front cover and / or the first left side plate of the rear cover are provided with a fourth indoor air inlet, which is beneficial to ensuring the heat exchange capacity of the second heat exchange section and the fourth heat exchange section.

[0011] In an optional embodiment of the above-mentioned portable air conditioner, it further includes: a duct cover plate, which is disposed on the top of the first indoor heat exchanger and the second indoor heat exchanger and abuts against the front cover and the rear cover, and the duct cover plate has a ventilation opening that matches the outline of the indoor fan.

[0012] The installation of the duct cover helps to seal the indoor duct space, ensuring that the air can exchange heat with the first and second indoor heat exchangers before flowing to the indoor air outlet, thereby ensuring the temperature regulation effect.

[0013] In the optional implementation of the above-mentioned portable air conditioner, it further includes: a flow guide ring, which is detachably arranged between the top cover plate and the air duct cover plate, wherein the shape of one end of the flow guide ring matches the shape of the indoor air outlet, and the shape of the other end matches the shape of the ventilation opening.

[0014] By incorporating airflow guide rings, the air driven by the indoor fan can be directed towards the indoor air outlet, resulting in a more concentrated and even flow of air through the outlet, thus improving air delivery efficiency. Furthermore, the airflow guide rings can serve as structural support, strengthening the connection between the duct cover and the top cover, preventing deformation or vibration.

[0015] In the optional implementation of the above-mentioned portable air conditioner, multiple sets of snap-fit ​​components are also arranged at intervals. The snap-fit ​​components include: a first buckle and a first slot, one of which is disposed on the outer wall surface of the air guide ring and the other is disposed on the air duct cover plate.

[0016] The first buckle and the first slot allow for a stable connection between the duct cover and the airflow ring. This facilitates disassembly of both components, enabling the replacement or cleaning of the duct space, duct cover, airflow ring, and indoor fan. It also ensures stable installation of the airflow ring, preventing it from shaking.

[0017] In the optional implementation of the above-mentioned portable air conditioner, it further includes: an indoor air outlet grille, which is disposed at the indoor air outlet and integrally formed with the air intake ring.

[0018] By integrating the indoor air outlet grille and the air intake ring into a single unit, structural stability can be improved, gaps between the air intake ring and the indoor air outlet grille can be avoided, thus preventing air leakage and noise problems. In addition, the number of structural components can be reduced, which is beneficial to improving installation efficiency.

[0019] In an optional embodiment of the above-mentioned portable air conditioner, a stepped portion recessed into the indoor heat exchange chamber is formed around the indoor air outlet. The horizontal step plate of the stepped portion abuts against the air guide ring, and a plurality of second slots are provided at intervals along the circumference of the horizontal step plate. The outer periphery of the indoor air outlet grille abuts against the outer wall surface of the top cover plate, and a plurality of second buckles that cooperate with the second slots are provided around the inner wall surface of the outer periphery.

[0020] By abutting the horizontal step plate against the air intake ring, and by abutting the outer periphery of the indoor air outlet grille against the outer wall of the top cover plate, air leakage at this point can be minimized, reducing noise; and by cooperating with the second buckle and the second slot, the installation of the air intake ring and the indoor air outlet grille can be stably achieved.

[0021] In the optional implementation of the above-mentioned portable air conditioner, it further includes: an outdoor air duct assembly having a fan cavity inside, the outdoor air duct assembly being disposed within the housing and dividing the interior of the housing into an indoor heat exchange cavity and an outdoor heat exchange cavity distributed vertically, wherein the outdoor heat exchange cavity is connected to the fan cavity; an outdoor fan being disposed in the fan cavity; and a motor assembly being installed in the outdoor air duct assembly and at least partially located within the indoor air duct space, the motor assembly having a first output shaft and a second output shaft arranged coaxially, the first output shaft being driven and connected to the indoor fan, and the second output shaft being driven and connected to the outdoor fan.

[0022] By fixing the motor assembly to the outdoor air duct assembly and setting up a motor assembly that is simultaneously connected to both the indoor fan and the outdoor fan drive, the number of components in the portable air conditioner can be further reduced, as well as the space it occupies, thereby further reducing the size of the portable air conditioner.

[0023] In an optional embodiment of the above-mentioned portable air conditioner, the back panel forms an outdoor cavity inlet communicating with the outdoor heat exchange cavity; the volute of the outdoor air duct assembly forms a fan outlet facing the back panel, and the fan outlet is connected to the outdoor cavity outlet on the back panel; the outdoor cavity inlet and the outdoor cavity outlet are respectively provided with a first grille and a second grille.

[0024] The outdoor cavity inlet and outlet are equipped with a first grille and a second grille, respectively, which helps to prevent foreign objects from entering the outdoor heat exchange cavity. Moreover, after installation, the structural strength and stability of the back panel can be improved, thereby enhancing the safety of the portable air conditioner. Attached Figure Description

[0045] Combination Figures 1 to 9 As shown, this utility model provides a portable air conditioner, including a housing 100, a first indoor heat exchanger 210, a second indoor heat exchanger 220, and an indoor fan 310.

[0046] The casing 100 internally defines an indoor heat exchange chamber 101, and the top cover plate 110 of the casing 100 is provided with an indoor air outlet 111 corresponding to the indoor heat exchange chamber 101. A first indoor heat exchanger 210 is disposed in the indoor heat exchange chamber 101, including a first heat exchange section 211 and a second heat exchange section 212 arranged in a bent manner. The casing 100 is provided with a first indoor air inlet 103 and a second indoor air inlet 104 corresponding to the first heat exchange section 211 and the second heat exchange section 212, respectively. A second indoor heat exchanger 220 includes a third heat exchange section 221 and a fourth heat exchange section 222 arranged in a bent manner, and is sequentially aligned with the first heat exchange section 211 and the second heat exchange section 212 to jointly enclose an indoor air duct space. The casing 100 is provided with a third indoor air inlet 105 and a fourth indoor air inlet 106 corresponding to the third heat exchange section 221 and the fourth heat exchange section 222, respectively. The indoor fan 310 is positioned above the indoor air duct space, corresponding to the indoor air outlet 111.

[0047] Optionally, the internal structure of the casing 100 is a cavity structure, which defines an independent indoor heat exchange cavity 101 and an outdoor heat exchange cavity 102. In this design, the indoor heat exchange cavity 101 and the outdoor heat exchange cavity 102 are arranged vertically. The indoor heat exchange cavity 101 is equipped with a first indoor heat exchanger 210 and a second indoor heat exchanger 220. The first indoor heat exchanger 210 and the second indoor heat exchanger 220 can exchange heat with the air flowing into the indoor heat exchange cavity 101 to regulate the air temperature.

[0048] Alternatively, the indoor heat exchange chamber 101 and the outdoor heat exchange chamber 102 can be connected and arranged side by side as needed.

[0049] Optionally, the first indoor heat exchanger 210 includes a first heat exchange section 211 and a second heat exchange section 212 arranged in a bent manner, and the second indoor heat exchanger 220 includes a third heat exchange section 221 and a fourth heat exchange section 222 arranged in a bent manner. In order to match the air intake of the indoor heat exchange chamber 101 with the heat exchange capacity of the first indoor heat exchanger 210 and the second indoor heat exchanger 220, a first indoor air inlet 103, a second indoor air inlet 104, a third indoor air inlet 105, and a fourth indoor air inlet 106 are respectively provided on the casing 100 at the positions corresponding to the first heat exchange section 211, the second heat exchange section 212, the third heat exchange section 221, and the fourth heat exchange section 222.

[0050] Optionally, the first heat exchange section 211, the second heat exchange section 212, the third heat exchange section 221, and the fourth heat exchange section 222 are arranged sequentially end-to-end to jointly enclose the indoor air duct space. Specifically, a gap is formed between the first indoor heat exchanger 210 and the second indoor heat exchanger 220 to facilitate the installation of U-shaped bends and / or liquid distributors and collectors. It should be noted that the first indoor heat exchanger 210 and the second indoor heat exchanger 220 are independent units, and a gap is formed between them. The sequential end-to-end arrangement refers to the sequential bending distribution of the first heat exchange section 211, the second heat exchange section 212, the third heat exchange section 221, and the fourth heat exchange section 222. A gap is formed between the first heat exchange section 211 and the fourth heat exchange section 222, and a gap is also formed between the second heat exchange section 212 and the third heat exchange section 221.

[0051] Optionally, the first heat exchange section 211 and the second heat exchange section 212 are connected in series. That is, the first heat exchange section 211 and the second heat exchange section 212 share a set of heat exchange tubes connected in series, making the first heat exchange section 211 and the second heat exchange section 212 an integral structure. In this way, the cooling capacity of the first heat exchange section 211 and the second heat exchange section 212 is superimposed, which can increase the cooling capacity of the portable air conditioner and reduce the welding operation of the heat pipe, thereby minimizing refrigerant leakage and improving safety. Similarly, the third heat exchange section 221 and the fourth heat exchange section 222 are connected in series. That is, the third heat exchange section 221 and the fourth heat exchange section 222 share a set of heat exchange tubes connected in series, making the third heat exchange section 221 and the fourth heat exchange section 222 an integral structure. In this way, the cooling capacity of the third heat exchange section 221 and the fourth heat exchange section 222 is superimposed, which can increase the cooling capacity of the portable air conditioner and reduce the welding operation of the heat pipe, thereby minimizing refrigerant leakage and improving safety.

[0052] Alternatively, the first heat exchange section 211 and the second heat exchange section 212 are connected in parallel. That is, the first heat exchange section 211 and the second heat exchange section 212 are relatively independent, and their heat exchange tubes are connected in parallel. To reduce structural complexity and cost, they share a single distributor and a collector, and each has a control valve at its respective refrigerant inlet. Thus, the operation of the first heat exchange section 211 and / or the second heat exchange section 212 can be controlled by 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. Similarly, the third heat exchange section 221 and the fourth heat exchange section 222 are connected in parallel. That is, the third heat exchange section 221 and the fourth heat exchange section 222 are relatively independent, and their heat exchange tubes are connected in parallel. To reduce structural complexity and cost, they share a single distributor and a collector, and each has a control valve at its respective refrigerant inlet. Thus, the operation of the third heat exchange section 221 and / or the fourth heat exchange section 222 can be controlled by the control valves according to the actual cooling capacity requirements. This improves the uniformity and stability of temperature during the operation of the portable air conditioner.

[0053] Optionally, a first end plate is provided at the end of the first heat exchange section 211 away from the second heat exchange section 212, and at the end of the second heat exchange section 212 away from the first heat exchange section 211, with the first end plate abutting against the inner side of the casing 100. Similarly, a second end plate is provided at the end of the third heat exchange section 221 away from the fourth heat exchange section 222, and at the end of the fourth heat exchange section 222 away from the third heat exchange section 221, with the second end plate abutting against the inner side of the casing 100. In this way, air entering the indoor heat exchange chamber 101 is prevented from flowing directly into the indoor air duct space without passing through the first indoor heat exchanger 210 / second indoor heat exchanger 220, thus improving the heat exchange effect.

[0054] Optionally, the first heat exchange section 211 and the fourth heat exchange section 222 have a bend angle between them, and they are arranged sequentially. In order to avoid the heat exchange effect being reduced due to excessive gap between them, a corner baffle can be provided between them, and the corner baffle abuts against the side of the first indoor heat exchanger 210 and the second indoor heat exchanger 220.

[0055] Optionally, an indoor fan 310 is installed within the formed indoor air duct space. Driven by the indoor fan 310, air flows, causing indoor air to enter the indoor heat exchange chamber 101 through one or more of the first indoor air inlet 103, the second indoor air inlet 104, the third indoor air inlet 105, and the fourth indoor air inlet 106. The indoor fan 310 is positioned within the indoor air duct space to prevent injury to users when their hands are inserted into the indoor heat exchange chamber 101. Alternatively, the indoor fan 310 is positioned above the indoor air duct space, i.e., close to the indoor air outlet 111, to improve the airflow efficiency of the indoor air outlet 111.

[0056] Optionally, the indoor fan 310 is an axial fan. This allows for a more compact structure and saves more space.

[0057] By adopting the above technical solution, by providing a first indoor air inlet 103, a second indoor air inlet 104, a third indoor air inlet 105, and a fourth indoor air inlet 106 on the casing 100, corresponding to the first indoor heat exchanger 210 and the second indoor heat exchanger 220, the air intake area of ​​the portable air conditioner can be increased, thereby ensuring the air intake volume. Simultaneously, the air entering the indoor heat exchange chamber 101 exchanges heat with the corresponding first heat exchange section 211, second heat exchange section 212, third heat exchange section 221, and fourth heat exchange section 222. This allows the portable air conditioner to have a small volume while possessing high heat exchange capacity and heat exchange efficiency, thus ensuring effective indoor air conditioning. Furthermore, the air after heat exchange flows back into the indoor environment through the indoor air outlet 111 provided on the top cover 110, avoiding direct airflow onto the user and improving comfort.

[0058] In the optional implementation of the above-mentioned portable air conditioner, the indoor fan 310 and the indoor air outlet 111 are coaxially arranged on the vertical central axis of the indoor air duct space; wherein, the vertical central axis of the indoor air duct space coincides with the vertical central axis of the indoor heat exchange chamber 101.

[0059] By arranging the indoor fan 310, indoor air outlet 111, and indoor air duct space coaxially, wind resistance can be effectively reduced and air flow efficiency can be improved. On the other hand, the structure of the portable air conditioner can be made more compact, saving space.

[0060] In the optional embodiment of the above-mentioned portable air conditioner, the housing 100 has a front cover 130 and a rear cover 120 that are connected to each other; the back panel 121 of the rear cover 120 is provided with a first indoor air inlet 103; the first left side panel 122 of the rear cover 120 and / or the second left side panel 132 of the front cover 130 are provided with a second indoor air inlet 104; the front panel 131 of the front cover 130 is provided with a third indoor air inlet 105; the second right side panel 133 of the front cover 130 and / or the first right side panel 123 of the rear cover 120 are provided with a fourth indoor air inlet 106. The first left side panel 122 and the second left side panel 32 can be connected accordingly; the first right side panel 123 and the second right side panel 133 can be connected accordingly.

[0061] Optionally, the front cover 130 and the rear cover 120 are snap-fitted together. The snap-fit ​​structure is simple, easy to manufacture, and easy to install and disassemble.

[0062] Specifically, the first left side panel 122 of the rear cover 120 is provided with a second indoor air inlet 104; or the second left side panel 132 of the front cover 130 is provided with a second indoor air inlet 104; or both the first left side panel 122 of the rear cover 120 and the second left side panel 132 of the front cover 130 are provided with second indoor air inlets 104 to increase the air intake area of ​​the second indoor air inlet 104.

[0063] Similarly, the second right side panel 133 of the front cover 130 is provided with a fourth indoor air inlet 106; or, the first right side panel 123 of the rear cover 120 is provided with a fourth indoor air inlet 106; or, both the second right side panel 133 of the front cover 130 and the first right side panel 123 of the rear cover 120 are provided with a fourth indoor air inlet 106 to increase the air intake area of ​​the fourth indoor air inlet 106.

[0064] Optionally, the first indoor air inlet 103 is composed of multiple sub-air inlets formed on the back panel 121. This eliminates the need for a separate air inlet grille, ensuring sufficient airflow while improving the overall structural strength of the back panel 121. Similarly, the second indoor air inlet 104 is composed of multiple sub-air inlets formed on the first left side panel 122, and / or multiple sub-air inlets formed on the second left side panel 132; the third indoor air inlet 105 is composed of multiple sub-air inlets formed on the front panel 131; and the fourth indoor air inlet 106 is composed of multiple sub-air inlets formed on the first right side panel 123, and / or multiple sub-air inlets formed on the second right side panel 133.

[0065] Alternatively, air inlet grilles are provided at the first indoor air inlet 103, the second indoor air inlet 104, the third indoor air inlet 105 and the fourth indoor air inlet 106 to prevent foreign objects such as mice and packaging paper from entering the indoor heat exchange chamber 101.

[0066] Optionally, the air intake grille disposed on the front cover 130 is integrally formed with the front cover 130 to improve the structural strength of the front cover 130 and reduce assembly errors. Similarly, the air intake grille disposed on the rear cover 120 is integrally formed with the rear cover 120.

[0067] Alternatively, the air intake grille provided on the front cover 130 is detachably connected to the front cover 130, for example, by snap-fit ​​or adhesive bonding. Similarly, the air intake grille provided on the rear cover 120 is detachably connected to the rear cover 120, for example, by snap-fit ​​or adhesive bonding.

[0068] It should be noted that, based on the user facing the front panel 131, the first left side panel 122, the second left side panel 132, the first right side panel 123, and the second right side panel 133 are defined according to the user's left and right sides.

[0069] In this design, by setting the housing 100 as a front cover 130 and a rear cover 120 that are connected to each other, it is beneficial to install and maintain the housing 100. The back panel 121 is provided with a first indoor air inlet 103, and the front panel 131 is provided with a third indoor air inlet 105 to ensure the heat exchange capacity of the first heat exchange section 211 and the third heat exchange section 221. Furthermore, the first right side panel 123 of the rear cover 120 and / or the second right side panel 133 of the front cover 130 are provided with a second indoor air inlet 104, and the second left side panel 132 of the front cover 130 and / or the first left side panel 122 of the rear cover 120 are provided with a fourth indoor air inlet 106, which is beneficial to ensure the heat exchange capacity of the second heat exchange section 212 and the fourth heat exchange section 222.

[0070] In an optional embodiment of the aforementioned portable air conditioner, a duct cover 230 is also included. The duct cover 230 covers the top of the first indoor heat exchanger 210 and the second indoor heat exchanger 220, and abuts against the front cover 130 and the rear cover 120. The duct cover 230 has a vent 231 that matches the contour of the indoor fan 310. When the indoor fan 310 is positioned above the indoor duct, the indoor fan 310 extends out of the duct cover 230.

[0071] Optionally, the duct cover 230 is detachably connected to the first end plate and the second end plate to improve the stability of the duct cover installation and prevent shaking and noise during the operation of the portable air conditioner.

[0072] The installation of the duct cover 230 facilitates the sealing of the indoor duct space, ensuring that the air can exchange heat with the first indoor heat exchanger 210 and the second indoor heat exchanger 220 before flowing to the indoor air outlet 111, thereby ensuring the temperature regulation effect.
