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, which internally defines an indoor heat exchange chamber, the casing including at least a top cover, a front cover and a rear cover that are connected to each other, the top cover having an indoor air outlet; 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, the front cover and / or the rear cover having an indoor air inlet corresponding to the indoor heat exchanger; an indoor fan, at least partially arranged within the space enclosed by the indoor heat exchanger; and a display module disposed in the front cover, the display module being arranged to avoid the indoor air inlet.

[0006] With the above technical solution, the indoor heat exchanger is constructed as a multi-stage heat exchanger, and both the front and / or rear covers are equipped with indoor air inlets corresponding to the indoor heat exchanger. Under the action of the indoor fan, indoor air flows through the indoor air inlets and then through the indoor heat exchanger, before flowing back into the indoor environment via the indoor air outlet located on the top cover. By placing the display module on the front cover and avoiding the indoor air inlets, it is possible to prevent low-temperature airflow from approaching the display module while ensuring easy observation of operating parameters by the user. This avoids condensation on the display module, improves its safety, and extends its service life.

[0007] In an optional embodiment of the above-mentioned portable air conditioner, the front cover includes a first side plate, a front panel, and a second side plate that are bent and connected in sequence, and both the first side plate and the second side plate are detachably connected to the rear cover; the display module is disposed in one of the front panel, the first side plate, and the second side plate.

[0008] By placing the display module in one of the front panel, the first side panel, or the second side panel, the versatility of the display module installation can be improved. Since the display module is arranged to avoid the indoor air intake, the space inside the casing can be fully utilized, thus improving space utilization.

[0009] In the optional implementation of the above-mentioned portable air conditioner, the indoor heat exchanger is provided and includes three sections, wherein the rear cover includes a third side plate, a back plate and a fourth side plate that are bent and connected in sequence, and the three sections of the indoor heat exchanger are respectively arranged corresponding to the third side plate, the back plate and the fourth side plate; the display module is disposed on the front panel and extends along the width direction of the front panel.

[0010] The indoor heat exchanger comprises three sections corresponding to the third side plate, back plate, and fourth side plate, respectively. By placing the display module on the front panel and extending it along the width of the front panel, it fully utilizes the space within the indoor heat exchange chamber and improves user viewing convenience while preventing low-temperature air passing through the indoor heat exchanger from flowing over the surface of the display module, thus avoiding condensation on the display module. Furthermore, driven by the indoor fan, it can also circulate the air around the display module, thereby improving the heat dissipation of the display module, further preventing condensation and effectively enhancing the safety of the display module.

[0011] In the optional implementation of the above-mentioned portable air conditioner, the indoor heat exchanger is provided and includes three sections, wherein the rear cover includes a third side plate, a back plate and a fourth side plate that are bent and connected in sequence, and the three sections of the indoor heat exchanger are respectively arranged corresponding to the third side plate, the back plate and the fourth side plate; the display module is disposed on the front panel and extends along the width direction of the front panel.

[0012] This arrangement positions the display module at the corner of the front casing. While fully utilizing the space within the indoor heat exchange chamber, it prevents the low-temperature air passing through the indoor heat exchanger from flowing over the surface of the display module, thus avoiding condensation. Simultaneously, driven by the indoor fan, it also circulates the air around the display module, improving heat dissipation and further preventing condensation, effectively enhancing the safety of the display module.

[0013] In the optional implementation of the above-mentioned portable air conditioner, there are two indoor heat exchangers arranged sequentially end to end, corresponding to the front cover and the rear cover respectively, and each indoor heat exchanger includes two sections; the display module is disposed on the front panel and extends along the width direction of the front panel, wherein the lower end surface of the display module is higher than the top of the indoor heat exchanger.

[0014] In this design, two indoor heat exchangers are installed, each consisting of two sections arranged end-to-end. Correspondingly, indoor air inlets are provided on both the front and rear covers. By installing a display module extending along its own width on the front panel, and positioning the lower end of the display module higher than the top of the indoor heat exchangers, the low-temperature air passing through the indoor heat exchangers can be prevented from flowing across the surface of the display module as much as possible, thereby reducing condensation on the display module and improving safety.

[0015] 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 display module is disposed between the top cover plate and the heat exchanger cover plate.

[0016] 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.

[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, a limiting rib extending toward the indoor heat exchange chamber is provided on the inner wall surface of the front cover, and the limiting rib encloses the receiving area of ​​the display module.

[0020] By setting the limiting ribs, the installation position of the display module can be limited, thereby improving the installation efficiency of the display module.

[0021] In the optional implementation 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 engaged with the limiting rib.

[0022] By using a display cover, the stability of the circuit board after installation can be improved, and the circuit board can be isolated from the air in the indoor heat exchange chamber. This also helps to prevent the display module from coming into contact with the low-temperature airflow and reduces condensation inside.

[0023] In an optional embodiment of the above-mentioned portable air conditioner, the end of the limiting rib facing the display cover is provided with a first step portion; the display cover includes a display cover plate and a side wall, and the end of the side wall facing the limiting rib is provided with a second step portion, the second step portion abutting and cooperating with the first step portion.

[0024] The first step and the second step abut against each other to achieve a sealed connection between the display box cover and the limiting rib, thereby improving the sealing performance of the accommodating area. Attached Figure Description

[0047] Combination Figures 1 to 16 As shown, this utility model provides a portable air conditioner, including: a housing 100, an indoor heat exchanger 210, an indoor fan 310, and a display module 400.

[0048] The housing 100 internally defines an indoor heat exchange chamber 101. The housing 100 includes at least a top cover 110, a front cover 120, and a rear cover 130 that are connected to each other. The top cover 110 has an indoor air outlet 111. An indoor heat exchanger 210 is disposed in the indoor heat exchange chamber 101 and is constructed as a multi-stage heat exchanger with bent connections. The front cover 120 and / or the rear cover 130 have indoor air inlets 103 corresponding to the indoor heat exchanger 210. An indoor fan 310 is at least partially arranged within the space enclosed by the indoor heat exchanger 210. A display module 400 is disposed in the front cover 120 and is arranged to avoid the indoor air inlet 103.

[0049] 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.

[0050] Optionally, the indoor heat exchange chamber 101 is equipped with at least an indoor heat exchanger 210 and an indoor fan 310, and the outdoor heat exchange chamber 102 is equipped with at least an outdoor heat exchanger 220 and a compressor. The indoor heat exchanger 210, the outdoor heat exchanger 220, and the compressor are connected by heat exchange pipes. Further, the indoor fan 310 is at least partially disposed within the space enclosed by the indoor heat exchanger 210 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 103, exchange heat with the indoor heat exchanger 210 to form a low-temperature airflow, and then flow to the indoor air outlet 111 through a shorter path, ensuring airflow efficiency.

[0051] Optionally, the indoor fan 310 is an axial fan and is positioned above the top of the indoor heat exchanger 210, between the top of the indoor heat exchanger 210 and the indoor air outlet 111. This allows for better concentration of low-temperature airflow, and results in a smaller size and smaller footprint, thereby reducing the overall size of the portable air conditioner.

[0052] Optionally, the housing 100 includes at least a front cover 120 and a rear cover 130 that abut against each other. Both are detachably connected to the top cover 110.

[0053] Optionally, the display module 400 is disposed on the front cover 120 and arranged to avoid the indoor air inlet 103. The placement of the display module 400 on the front cover 120 allows the user to easily observe and adjust the operating parameters displayed on the module. Furthermore, the arrangement of the display module 400 to avoid the indoor air inlet 103 prevents low-temperature airflow from the indoor heat exchanger 210 from flowing past or approaching the display module 400, thereby preventing condensation on the display module 400, improving its safety, and extending its service life.

[0054] Optionally, an air outlet grille is provided at the indoor air outlet 111 to disperse the airflow and prevent foreign objects from entering the indoor heat exchange chamber 101.

[0055] Optionally, the indoor air inlet 103 is composed of multiple circular through holes. Alternatively, the indoor air inlet 103 is a larger opening with an air intake grille at the opening.

[0056] With the above technical solution, the indoor heat exchanger is constructed as a multi-stage heat exchanger, and both the front and / or rear covers are equipped with indoor air inlets corresponding to the indoor heat exchanger. Under the action of the indoor fan, indoor air flows through the indoor air inlets and then through the indoor heat exchanger, before flowing back into the indoor environment via the indoor air outlet located on the top cover. By placing the display module on the front cover and avoiding the indoor air inlets, it is possible to prevent low-temperature airflow from approaching the display module while ensuring easy observation of operating parameters by the user. This avoids condensation on the display module, improves its safety, and extends its service life.

[0057] In an optional embodiment of the aforementioned portable air conditioner, the front cover 120 includes a first side panel 121, a front panel 122, and a second side panel 123 connected in sequence by bending. Both the first side panel 121 and the second side panel 123 are detachably connected to the rear cover 130. The display module 400 is disposed in one of the front panel 122, the first side panel 121, and the second side panel 123.

[0058] By placing the display module 400 in one of the front panel 122, the first side panel 121, and the second side panel 123, the installation versatility of the display module 400 can be improved. Since the display module 400 is arranged to avoid the indoor air inlet 103, that is, to avoid the indoor heat exchanger 210, the space inside the housing 100 can be fully utilized, thereby improving space utilization.

[0059] In the optional implementation scheme of the aforementioned portable air conditioner, combined with Figure 1 , Figure 2 , Figure 6 , Figure 7 as well as Figure 10 As shown, the indoor heat exchanger 210 has one and includes three sections. The rear cover 130 includes a third side plate 131, a back plate 132, and a fourth side plate 133 that are bent and connected in sequence. The indoor heat exchanger 210 is arranged corresponding to the third side plate 131, the back plate 132, and the fourth side plate 133. The display module 400 is disposed on the front panel 122 and extends along the width direction of the front panel 122.

[0060] Specifically, the indoor heat exchanger 210 has one and three sections, forming a U-shaped heat exchanger. The indoor heat exchanger 210 is arranged corresponding to the rear cover 130. The rear cover 130 includes a third side plate 131, a back plate 132, and a fourth side plate 133 connected in sequence by bending. The third side plate 131, the back plate 132, and the fourth side plate 133 are respectively provided with indoor air inlets 103 corresponding to the indoor heat exchanger 210. The third side plate 131 is connected to the first side plate 121, and the fourth side plate 133 is connected to the second side plate 123. Specifically, the front panel 122 does not have an indoor air inlet 103. Thus, there is no low-temperature airflow, and condensation will not occur on the display module 400. It should be noted that in this solution, the width direction of the front panel 122 refers to the direction from the first side plate 121 to the second side plate 123.

[0061] In this solution, the indoor heat exchanger 210 includes three sections corresponding to the third side plate 131, the back plate 132, and the fourth side plate 133, respectively. By setting the display module 400 on the front panel 122 and extending it along the width direction of the front panel 122, the space inside the indoor heat exchange cavity 101 can be fully utilized and the user's observation convenience can be improved. At the same time, the low-temperature air passing through the indoor heat exchanger 210 is prevented from flowing over the surface of the display module 400, thereby preventing condensation from forming on the display module 400.

[0062] Furthermore, driven by the indoor fan 310, the air around the display module 400 can be circulated, thereby improving the heat dissipation of the display module 400, further preventing condensation, and effectively enhancing the safety of the display module 400.

[0063] Alternatively, instead of providing the first side panel 121 and the second side panel 123, the third side panel 131 and the fourth side panel 133 are connected to the corresponding two sides of the front panel 122. This reduces the space occupied by the portable air conditioner and lowers its size.

[0064] Alternatively, the display module 400 is positioned along the height of the front panel 122.

[0065] In the optional implementation scheme of the aforementioned portable air conditioner, combined with Figure 4 , Figure 5 as well as Figure 10 As shown, the indoor heat exchanger 210 has one and includes three sections. The rear cover 130 includes a third side plate 131, a back plate 132, and a fourth side plate 133 that are bent and connected in sequence. The indoor heat exchanger 210 is arranged corresponding to the third side plate 131, the back plate 132, and the fourth side plate 133. The display module 400 is disposed on the first side plate 121 or the second side plate 123 and extends along the height direction of the first side plate 121 or the second side plate 123.

[0066] This arrangement positions the display module 400 at the corner of the front cover 120. While fully utilizing the space within the indoor heat exchange chamber 101, it prevents the low-temperature air passing through the indoor heat exchanger 210 from flowing over the surface of the display module 400, thus avoiding condensation on the display module 400. Simultaneously, driven by the indoor fan 310, it also circulates the air around the display module 400, improving its heat dissipation and further preventing condensation, effectively enhancing the safety of the display module 400.

[0067] Specifically, the first side panel 121 is bent and connected to the front panel 122, and the second side panel 123 is bent and connected to the front panel 122. Since the indoor heat exchanger 210 is not located at the position corresponding to the front cover 120, no airflow passes through the front panel 122. Thus, driven by the indoor fan 310, the air around the display module 400 will circulate to carry away the heat generated by the display module 400. The display module 400 will not come into contact with the low-temperature airflow formed after passing through the indoor heat exchanger 210.

[0068] Furthermore, the display module 400 is arranged close to the front panel on the first side panel 121 / second side panel 123.

[0069] In the optional implementation scheme of the aforementioned portable air conditioner, combined with Figure 8 , Figure 9 as well as Figure 11 As shown, the indoor heat exchanger 210 has two units arranged sequentially, one end to the other, corresponding to the front cover 120 and the other end to the rear cover 130. Each indoor heat exchanger 210 includes two sections. The display module 400 is disposed on the front panel 122 and extends along the width direction of the front panel 122. The lower end surface of the display module 400 is higher than the top of the indoor heat exchanger 210.

[0070] It should be noted that in this solution, the width direction of the front panel 122 refers to the direction from the first side panel 121 to the second side panel 123.

[0071] Optionally, two indoor heat exchangers 210 are provided and are arranged end to end, forming an L-shaped heat exchanger. The two indoor heat exchangers 210 are arranged corresponding to the front cover 120 and the rear cover 130, that is, both the front cover 120 and the rear cover 130 are provided with indoor air inlets 103.

[0072] Specifically, the third side panel 131, the back panel 132 and the fourth side panel 133, as well as the first side panel 121, the front panel 122 and the second side panel 123, are each provided with an indoor air inlet 103 corresponding to the indoor heat exchanger 210.

[0073] In this design, two indoor heat exchangers 210 are provided, and each indoor heat exchanger 210 includes two sections, which are arranged end to end in sequence. Correspondingly, indoor air inlets 103 are provided on both the front cover 120 and the rear cover 130. By providing a display module 400 extending along its own width on the front panel 122, and setting the lower end surface of the display module 400 higher than the top of the indoor heat exchanger 210, the low-temperature air passing through the indoor heat exchanger 210 can be prevented from flowing across the surface of the display module 400 as much as possible, thereby reducing condensation on the display module 400 and improving safety.

[0074] Alternatively, combined Figure 11 , Figures 13 to 16 As shown, the upper surface of the display module 400 is flush with the top of the indoor heat exchanger 210. The display module 400 is disposed on the front panel 122 and extends along the width / height direction of the front panel 122. Alternatively, the display module 400 is disposed on the first side plate 121 / second side plate 123 and extends along the height direction of the first side plate 121 / second side plate 123.

[0075] In this way, the air flowing into the indoor heat exchange chamber 101 flows over the surface of the display module 400 before exchanging heat with the indoor heat exchanger 210, so as to drive the air around the display module 400 to flow, and does not come into contact with the low temperature airflow, which can avoid condensation to a certain extent.

[0076] Furthermore, to prevent heat generated by the indoor heat exchanger 210 from being transferred to the display module 400, a heat insulation layer is provided on the side of the display module 400 facing the indoor heat exchanger 210. Alternatively, a heat insulation layer is provided on all four sides of the display module 400.

[0077] In an optional embodiment of the aforementioned portable air conditioner, a heat exchanger cover 510 is also included. The heat exchanger cover 510 covers the top of the indoor heat exchanger 210 and abuts against the casing 100. The heat exchanger cover 510 has a ventilation opening 511. The display module is disposed between the top cover 110 and the heat exchanger cover 510.

[0078] By setting the heat exchanger cover plate 510, a relatively sealed space can be formed between the top cover plate 110 and the heat exchanger cover plate 510. Driven by the indoor fan 310, the low-temperature airflow flowing through the indoor heat exchanger 210 flows to the indoor air outlet 111 through the vent 511, which can prevent the low-temperature air from dissipating and flowing over the surface of the display module 400, thereby minimizing the generation of condensation.

[0079] Optionally, the heat exchanger cover 510 abuts against the inner wall surface of the housing 100. Further, the heat exchanger cover 510 is interference-fitted with the housing 100.

[0080] Alternatively, the heat exchanger cover plate 510 may not be provided.

[0081] In an optional embodiment of the aforementioned portable air conditioner, a guide air duct 520 is also included. The guide air duct 520 connects the vent 511 and the indoor air outlet 111, and is arranged around the indoor fan 310.

[0082] By setting up the air duct 520, the low-temperature airflow passing through the indoor heat exchanger 210 can flow to the indoor air outlet 111 through the sealed air duct 520, thereby isolating the low-temperature airflow from the display module 400, thus preventing condensation from forming on the display module 400 and improving safety.

[0083] In the optional embodiment of the above-mentioned portable air conditioner, the inner wall surface of the front cover 120 is provided with a limiting rib 124 extending toward the indoor heat exchange chamber 101, and the limiting rib 124 encloses the receiving area of ​​the display module 400.

[0084] By setting the limiting rib 124, the installation position of the display module 400 can be limited, thereby improving the installation efficiency of the display module 400.

[0085] Alternatively, limit ribs 124 can be omitted.

[0086] In the optional implementation of the above-mentioned portable air conditioner, the display module 400 has at least a display cover 410 and a circuit board 420, the circuit board 420 is fixed in the receiving area, and the display cover 410 is engaged with the limiting rib 124.

[0087] By using a display cover, the stability of the circuit board after installation can be improved, and the circuit board can be isolated from the air in the indoor heat exchange chamber. This also helps to prevent the display module from coming into contact with the low-temperature airflow and reduces condensation inside.

[0088] In this design, the circuit board is installed within the receiving area between the display box cover 410 and the limiting rib 124. Alternatively, the display module 400 includes a display box body and a circuit board disposed within the display box body. The display box body is disposed within the receiving area.

[0089] Alternatively, the display cover 410 is screwed, plugged in, or riveted to the limiting rib 124.
