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 need to be fixed 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 using related technologies, the indoor unit is typically configured with side-intake and top-outtake airflow, and the evaporator is usually a direct-vent evaporator. That is, the indoor airflow inlet is located on the side panel of the outer casing, and the indoor airflow outlet is located on the top panel. The evaporator faces the indoor airflow inlet, and an indoor fan is located on the outlet side of the evaporator, connected to the indoor airflow outlet. To allow users to easily and intuitively understand the operating parameters of the portable air conditioner, the display device is located on the top panel, above the evaporator. However, during operation, because the evaporator temperature is low while the display module temperature rises, condensation can easily form on the surface of the display device, potentially causing short circuits and other safety issues. Utility Model Content

[0004] The present invention aims to solve the above-mentioned technical problem, namely, to solve the problem that the display module of a portable air conditioner is prone to condensation.

[0005] This utility model provides a portable air conditioner, comprising: a casing, internally defining an indoor heat exchange chamber, the casing including at least a top cover plate corresponding to the indoor heat exchange chamber, the top cover plate having a circular indoor air outlet; an indoor air outlet grille disposed at the indoor air outlet, including a baffle located in the middle of the indoor air outlet and grille strips surrounding the baffle; an indoor heat exchanger disposed in the indoor heat exchange chamber, the indoor heat exchanger being constructed as a multi-segment heat exchanger with bent connections; an indoor fan, at least partially arranged within the space enclosed by the indoor heat exchanger; and a display module disposed on the top cover plate or on the baffle plate, avoiding the indoor heat exchanger.

[0006] By adopting the above technical solutions, placing the display module on the top cover plate in a position that avoids the heat exchanger can reduce contact with the low-temperature airflow passing through the indoor heat exchanger. At the same time, the indoor fan can drive the airflow around the display module, thereby preventing condensation. Alternatively, since the indoor air outlet is constructed in a circular shape, no low-temperature airflow passes through the center. Therefore, placing the display module on a baffle located in the center of the indoor air outlet can prevent the display module from contacting the low-temperature airflow, thereby preventing condensation. Thus, the safety of the display module can be improved and its service life extended.

[0007] In an optional embodiment of the above-mentioned portable air conditioner, the indoor heat exchanger is provided in one and includes three sections, and the opening of the indoor heat exchanger faces the front panel of the casing; the display module is located on the front end of the top cover corresponding to the front panel; or, the display module is disposed on the inner panel surface of the baffle.

[0008] In this way, the low-temperature airflow after passing through the indoor heat exchanger can be completely avoided from contacting the display module, thereby reducing or even eliminating the generation of condensation.

[0009] In an optional embodiment of the above-mentioned portable air conditioner, the indoor heat exchanger is provided with two side plates arranged in a sequentially corresponding manner and each side plate is respectively corresponding to the outer shell, and each indoor heat exchanger includes two sections; the display module is disposed on the top cover plate and corresponds to the gap between the two indoor heat exchangers; or, the display module is disposed on the inner plate surface of the baffle.

[0010] The display module is located on the top cover plate and corresponds to the gap between the two indoor heat exchangers. There is no low-temperature airflow here, and the surrounding air can flow under the drive of the indoor fan to cool the display module, thereby reducing or even avoiding the generation of condensation. When the display module is located on the inner plate of the baffle, the center of the indoor air outlet is the center of the vortex and there is no airflow. Therefore, it can reduce contact with the low-temperature airflow, thereby reducing or even avoiding the generation of condensation.

[0011] In an optional embodiment of the above-mentioned portable air conditioner, the indoor fan, the indoor air outlet, and the baffle are arranged coaxially.

[0012] By arranging the indoor fan, indoor air outlet, and baffle coaxially, it can be ensured that no airflow passes through the baffle or even the area around the baffle, thereby preventing condensation from forming on the display module located at the baffle.

[0013] In the optional implementation of the above-mentioned portable air conditioner, it further includes: a heat exchanger cover plate, which is placed on the top of the indoor heat exchanger and abuts against the casing, and the heat exchanger cover plate has a ventilation opening; wherein, the indoor fan is located between the top cover plate and the heat exchanger cover plate.

[0014] By setting up the heat exchanger cover, a relatively sealed space can be formed between the top cover and the heat exchanger cover. Driven by the indoor fan, the low-temperature airflow flowing through the indoor heat exchanger flows to the indoor air outlet through the vent, which can prevent the low-temperature air from dissipating and flowing over the surface of the display module, thereby minimizing the generation of condensation.

[0015] In an optional embodiment of the above-mentioned portable air conditioner, the vent is arranged coaxially with the indoor air outlet.

[0016] By arranging the ventilation openings and indoor air outlets coaxially, the flow path of low-temperature airflow can be reduced, airflow efficiency can be improved, and energy loss can be avoided; at the same time, it can further ensure that the low-temperature airflow does not come into contact with the display module.

[0017] In an optional embodiment of the above-mentioned portable air conditioner, a guide air duct is further included, which connects the vent and the indoor air outlet and is arranged around the indoor fan.

[0018] By setting up a guide duct, the low-temperature airflow passing through the indoor heat exchanger can flow to the indoor air outlet through the sealed guide duct, thereby isolating the low-temperature airflow from the display module, thus preventing condensation from forming on the display module and improving safety.

[0019] In an optional embodiment of the above-mentioned portable air conditioner, the air duct and the indoor air outlet grille are integrally formed.

[0020] By integrating the airflow guide duct with the air outlet grille, leakage of low-temperature airflow to the outside of the airflow guide duct can be prevented. This ensures that the low-temperature airflow flows along the path defined by the airflow guide duct to the indoor air outlet, preventing low-temperature airflow from escaping to the vicinity of the display module when it is installed on the top cover.

[0021] In an optional embodiment of the above-mentioned portable air conditioner, the inner surface of the top cover or the inner surface of the baffle is provided with a limiting rib extending toward the indoor heat exchange chamber, and the limiting rib encloses the receiving area of ​​the display module.

[0022] By setting the limiting ribs, the installation position of the display module can be limited, thereby improving the installation efficiency of the display module.

[0023] In an optional embodiment of the above-mentioned portable air conditioner, the display module has at least a display cover and a circuit board, the circuit board is fixed in the receiving area, and the display cover is detachably connected to the limiting rib.

[0024] The detachable combination of the display box cover and the top cover / baffle can isolate the circuit board, preventing the display module from contacting the low-temperature airflow to a certain extent and avoiding condensation on the circuit board; while protecting the circuit board, it also facilitates later replacement or maintenance.

[0049] Combination Figures 1 to 11As shown, this utility model provides a portable air conditioner, including: a housing 100, an indoor air outlet grille 200, an indoor heat exchanger 310, an indoor fan 410, and a display module 500.

[0050] The housing 100 internally defines an indoor heat exchange chamber 101. The housing 100 includes at least a top cover plate 110 corresponding to the indoor heat exchange chamber 101, and a circular right indoor air outlet 111 is constructed on the top cover plate 110. An indoor air outlet grille 200 is disposed at the indoor air outlet 111, including a baffle 210 located in the middle of the indoor air outlet 111 and grille members 220 surrounding the baffle 210. An indoor heat exchanger 310 is disposed in the indoor heat exchange chamber 101, and the indoor heat exchanger 310 is constructed as a multi-stage heat exchanger with bent connections. An indoor fan 410 is arranged at least within the space enclosed by the indoor heat exchanger 310. A display module 500 is disposed on the top cover plate 110 or on the baffle 210, avoiding the indoor heat exchanger 310.

[0051] Optionally, a cavity is formed within the casing 100, and the cavity is divided into an indoor heat exchange chamber 101 and an outdoor heat exchange chamber 102. In this design, the indoor heat exchange chamber 101 and the outdoor heat exchange chamber 102 are arranged vertically. Alternatively, the indoor heat exchange chamber 101 and the outdoor heat exchange chamber 102 are arranged horizontally.

[0052] Optionally, the indoor heat exchange chamber 101 is equipped with at least an indoor heat exchanger 310 and an indoor fan 410, and the outdoor heat exchange chamber 102 is equipped with at least an outdoor heat exchanger 320 and a compressor. The indoor heat exchanger 310, the outdoor heat exchanger 320, and the compressor are connected by heat exchange pipelines.

[0053] Optionally, the housing 100 is provided with an indoor air inlet 121 corresponding to the indoor heat exchanger 310, and the indoor fan 410 is at least partially disposed within the space enclosed by the indoor heat exchanger 310 and is located near the indoor air outlet 111. In this way, air from the indoor environment can be driven into the indoor heat exchange chamber 101 through the indoor air inlet 121, exchange heat with the indoor heat exchanger 310 to form a low-temperature airflow, and then flow to the indoor air outlet 111 through a shorter path, ensuring airflow efficiency.

[0054] Optionally, the indoor fan 410 is an axial fan and is positioned above the top of the indoor heat exchanger 310, that is, between the top of the indoor heat exchanger 310 and the indoor air outlet 111. This allows for a more concentrated low-temperature airflow, and results in a smaller size and smaller footprint, thereby reducing the overall size of the portable air conditioner.

[0055] Optionally, the indoor air outlet 111 is constructed in a circular shape to avoid the generation of dead airflow and improve airflow efficiency.

[0056] Optionally, the indoor air outlet grille 200 includes a baffle 210 and grille members 220 surrounding the baffle 210. Further, the grille member 220 includes annular grille bars 221 and radial grille bars 222. Multiple annular grille bars 221 are coaxially arranged with the baffle 210 and are arranged radially spaced along the indoor air outlet 111. Multiple radial grille bars 222 extend radially along the indoor air outlet 111. Multiple radial grille bars 222 are arranged circumferentially around the indoor air outlet 111. All radial grille bars 222 are fixedly connected to the baffle 210, and each radial grille bar 222 is cross-connected to multiple annular grille bars 221. Further, the indoor air outlet grille 200 also includes a connecting side 230. The connecting side 230 is detachably connected to the top cover plate 110. Specifically, the connecting side 230 and the top cover plate 110 are fixedly connected by one or more of the following methods: snap-fit, screw connection, and plug-in connection.

[0057] Optionally, wiring channels for the display module 500 can be provided on the radial grille strips 222 and the top cover plate 110 to facilitate electrical connection between the display module 500 and the power supply module of the portable air conditioner.

[0058] Optionally, the indoor fan 410 is positioned below the indoor air outlet 111. Since the indoor air outlet 111 is circular, airflow typically does not pass through its center; that is, low-temperature airflow does not flow through the center of the indoor air outlet 111. Positioning the display module 500 on a baffle 210 located in the center of the indoor air outlet 111 reduces or even eliminates contact between the display module 500 and the low-temperature airflow flowing through the indoor heat exchanger 310, thereby reducing or even eliminating condensation.

[0059] Optionally, the display module 500 is disposed on the top cover plate 110, avoiding the arrangement of the indoor heat exchanger 310. Specifically, this avoidance can be understood as the projections of the two on the top cover plate 110 not overlapping completely or partially; or, after the display module 500 projects towards the indoor heat exchanger 310, there is no intersecting area between them. In this way, contact with the low-temperature airflow passing through the indoor heat exchanger 310 can be reduced. At the same time, the indoor fan 410 can drive the air circulation around the display module 500, improving the cooling effect of the display module 500, thereby preventing the display module 500 from overheating and thus avoiding condensation.

[0060] By adopting the above technical solution, by placing the display module 500 on the top cover plate 110 at a position that avoids the indoor heat exchanger 310, the contact between the display module 500 and the low-temperature airflow passing through the indoor heat exchanger 310 can be reduced. At the same time, the indoor fan 410 can drive the airflow around the display module 500, thereby avoiding condensation. Alternatively, since the indoor air outlet 111 is constructed as a circle and no low-temperature airflow passes through the center, the display module 500 can be placed on the baffle 210 located in the center of the indoor air outlet 111, which can prevent the display module 500 from contacting the low-temperature airflow, thereby avoiding condensation. Therefore, the safety of the display module 500 can be improved and its service life can be extended.

[0061] In the optional implementation scheme of the aforementioned portable air conditioner, combined with Figures 1 to 6 As shown, the indoor heat exchanger 310 has one and includes three sections, and the opening of the indoor heat exchanger 310 faces the front panel 130 of the casing 100; the display module 500 is located on the front end 112 of the top cover plate 110 corresponding to the front panel 130; or, the display module 500 is disposed on the inner plate surface of the baffle 210.

[0062] Optionally, the indoor heat exchanger 310 has one and three sections, i.e., the indoor heat exchanger 310 is constructed as a U-shaped heat exchanger. All three sections of the indoor heat exchanger 310 are arranged vertically, so the opening formed by the U-shaped heat exchanger faces one side of the casing 100. In this design, the opening of the indoor heat exchanger 310 faces the front panel 130 of the casing 100. Thus, when the display module 500 is located at the front end 112 of the top cover 110 corresponding to the front panel 130, it facilitates user operation and observation of operating parameters, and the display module 500 is further away from the indoor heat exchanger 310, thereby reducing or even eliminating condensation. Furthermore, driven by the indoor fan 410, the airflow around the display module 500 can remove heat from the display module 500, thereby preventing the display module 500 from overheating and reducing or even eliminating condensation.

[0063] Alternatively, the display module 500 can be disposed on the inner surface of the baffle 210 to avoid contact with the low-temperature airflow and to protect the display module 500. Furthermore, a heat insulation layer is provided on the outer peripheral surface of the display module 500.

[0064] In this way, the low-temperature airflow after passing through the indoor heat exchanger 310 can be completely avoided from contacting the display module 500, thereby reducing or even avoiding the generation of condensation.

[0065] Alternatively, the display module 500 is disposed on the outer surface of the baffle 210.

[0066] In this design, the inner surface of the baffle 210 refers to the side facing the indoor heat exchange chamber 101. The outer surface of the baffle 210 is arranged opposite to the inner surface of the baffle 210.

[0067] Optionally, in this solution, the front panel 130 has one or more through holes corresponding to the display module 500. In this way, indoor air entering the indoor heat exchange chamber can flow through the display module under the drive of the indoor fan 410, accelerating the air circulation around the display module 500, thereby achieving cooling of the display module 500.

[0068] Furthermore, when a heat exchanger cover plate 610 and / or a guide air duct 620 are provided, the arrangement of the through holes is more conducive to the circulation of air around the display module 500.

[0069] Optionally, the through-holes surround the circumferentially spaced display module 500.

[0070] Alternatively, no through-holes can be provided.

[0071] In the optional implementation scheme of the aforementioned portable air conditioner, combined with Figures 7 to 12 As shown, the indoor heat exchanger 310 has two side plates arranged in a sequential manner, each corresponding to a plurality of different side plates of the casing 100. Each indoor heat exchanger 310 includes two sections. The display module 500 is disposed on the top cover plate 110 and corresponds to the gap between the two indoor heat exchangers 310. Alternatively, the display module 500 is disposed on the inner plate surface of the baffle 210.

[0072] Optionally, two indoor heat exchangers 310 are provided, one end to the other, forming an L-shaped heat exchanger. The two indoor heat exchangers 310 are respectively arranged on different side panels of the casing 100. Further, the casing 100 includes at least a front panel 130, a left side panel, a back panel, and a right side panel that are bent and connected in sequence. Specifically, one indoor heat exchanger 310 is arranged corresponding to the front panel 130 and the left side panel, and the other indoor heat exchanger is arranged corresponding to the back panel and the right side panel. The front panel 130, the left side panel, the back panel, and the right side panel are all provided with indoor air inlets 121. At this time, when the display module 500 is placed on the top cover plate 110 and corresponding to the gap between the two indoor heat exchangers 310, the surrounding air can flow under the drive of the indoor fan to cool the display module 500, thereby reducing or even avoiding the generation of condensation. Moreover, there is no generation or flow of low-temperature airflow at this gap, and the display module 500 and the indoor heat exchanger 310 have a certain distance, thereby reducing or avoiding the generation of condensation.

[0073] Alternatively, the housing 100 includes a mating front cover and a rear cover, the front cover having a first sub-left side panel, a front panel, and a first sub-right side panel, and the rear cover having a second sub-left side panel, a back panel, and a second sub-right side panel. The first sub-left side panel and the second sub-left side panel are mated together, and the first sub-right side panel and the second sub-right side panel are mated together. One indoor heat exchanger 310 is arranged corresponding to the front panel 130 and the first sub-left side panel, and another indoor heat exchanger is arranged corresponding to the back panel and the second sub-right side panel. Alternatively, one indoor heat exchanger 310 is arranged corresponding to the front panel 130 and the second sub-left side panel, and another indoor heat exchanger is arranged corresponding to the back panel and the first sub-right side panel.

[0074] Alternatively, the display module 500 can be disposed on the inner surface of the baffle 210 to avoid contact with the low-temperature airflow and to protect the display module 500. Furthermore, a heat insulation layer is provided on the outer peripheral surface of the display module 500.

[0075] Alternatively, the display module 500 is disposed on the outer surface of the baffle 210.

[0076] In this design, the inner surface of the baffle 210 refers to the side facing the indoor heat exchange chamber 101. The outer surface of the baffle 210 is arranged opposite to the inner surface of the baffle 210.

[0077] The display module 500 is mounted on the top cover plate 110 and corresponds to the gap between the two indoor heat exchangers 310. There is no low-temperature airflow here, and the surrounding air can flow under the drive of the indoor fan 410 to cool the display module 500, thereby reducing or even avoiding the generation of condensation. When the display module 500 is mounted on the inner plate of the baffle 210, the center of the indoor air outlet 111 is the center of the vortex and there is no airflow. Therefore, it can reduce contact with the low-temperature airflow, thereby reducing or even avoiding the generation of condensation.

[0078] In the optional implementation of the above-mentioned portable air conditioner, the indoor fan 410 is arranged coaxially with the indoor air outlet 111 and the baffle 210.

[0079] By arranging the indoor fan, indoor air outlet, and baffle coaxially, it can be ensured that no airflow passes through the baffle or even the area around the baffle, thereby preventing condensation from forming on the display module located at the baffle.

[0080] In the optional implementation of the above-mentioned portable air conditioner, a heat exchanger cover plate 610 is also included. The heat exchanger cover plate 610 is installed on the top of the indoor heat exchanger 310 and abuts against the casing 100. The heat exchanger cover plate 610 has a ventilation opening 611. The indoor fan 410 is located between the top cover plate 110 and the heat exchanger cover plate 610.

[0081] By setting the heat exchanger cover plate 610, a relatively sealed space can be formed between the top cover plate 110 and the heat exchanger cover plate 610. Driven by the indoor fan 410, the low-temperature airflow flowing through the indoor heat exchanger 310 flows to the indoor air outlet 111 through the vent 611, which can prevent the low-temperature air from dissipating and flowing over the surface of the display module 500, thereby minimizing the generation of condensation.

[0082] Optionally, the heat exchanger cover 610 abuts against the inner wall surface of the casing 100. Further, the heat exchanger cover 610 is interference-fitted with the casing 100.

[0083] Alternatively, the heat exchanger cover plate 610 may not be provided.

[0084] In the optional implementation of the above-mentioned portable air conditioner, the vent 611 and the indoor air outlet 111 are arranged coaxially.

[0085] By arranging the vent 611 and the indoor air outlet 111 coaxially, the flow path of the low-temperature airflow can be reduced, the air outlet efficiency can be improved, and energy loss can be avoided. At the same time, it can further ensure that the low-temperature airflow flows directly to the indoor air outlet 111 under the drive of the indoor fan 410, so as not to come into contact with the display module 500.

[0086] In an optional embodiment of the aforementioned portable air conditioner, a guide air duct 620 is also included. The guide air duct 620 connects the vent 611 and the indoor air outlet 111, and is arranged around the indoor fan 410.

[0087] Specifically, one end of the air guide duct 620 is inserted into the vent 611 and abuts against the periphery of the vent 611, while the other end of the air guide duct 620 is fixedly connected to the connecting side 230.

[0088] By setting up the air duct 620, the low-temperature airflow passing through the indoor heat exchanger 310 can flow to the indoor air outlet through the sealed air duct 620, thereby isolating the low-temperature airflow from the display module 500, thus preventing condensation from forming on the display module 500 and improving safety.

[0089] Alternatively, no airflow duct 620 may be installed.

[0090] In the optional implementation of the above-mentioned portable air conditioner, the air duct 620 and the indoor air outlet grille 200 are integrally formed.

[0091] Specifically, the other end of the air duct 620 is integrally formed with the connecting side 230 of the indoor air outlet grille 200. Furthermore, the indoor air outlet grille 200 is integrally formed as a whole.

[0092] By integrating the air duct 620 with the indoor air outlet grille 200, leakage of low-temperature airflow to the outside of the air duct 620 can be prevented. This allows the low-temperature airflow to flow along the path defined by the air duct 620 to the indoor air outlet, preventing the low-temperature airflow from escaping to the vicinity of the display module 500 when the display module 500 is installed on the top cover plate 110.

[0093] Alternatively, the other end of the air duct 620 is fixedly connected to the connecting side 230 of the indoor air outlet grille 200. This fixed connection includes methods such as plug-in and butt-joint connections.

[0094] Alternatively, no airflow duct 620 may be installed.

[0095] In the optional implementation of the above-mentioned portable air conditioner, the inner surface of the top cover plate 110 or the inner surface of the baffle 210 is provided with a limiting rib 710 extending toward the indoor heat exchange chamber 101, and the limiting rib 710 encloses the receiving area of ​​the display module 500.

[0096] By setting the limiting rib 710, the installation position of the display module 500 can be limited, thereby improving the installation efficiency of the display module 500.

[0097] Optionally, when the limiting rib 710 is provided on the inner plate surface of the baffle 210, it is fixedly connected to the radial grid strip 222.

[0098] In the optional implementation of the above-mentioned portable air conditioner, the display module 500 has at least a display cover 510 and a circuit board, the circuit board is fixed in the receiving area, and the display cover 510 is detachably connected to the limiting rib 710.

[0099] The detachable connection between the display box cover 510 and the top cover plate 110 / baffle 210 can isolate the circuit board, thereby preventing the display module 500 from contacting the low-temperature airflow and preventing condensation on the circuit board. While protecting the circuit board, it also facilitates future replacement or maintenance.
