Description

Technical Field

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

[0002] Currently, both wall-mounted and floor-standing air conditioners must be fixed in a defined location and cannot be moved. Therefore, mobile air conditioners have emerged. Mobile air conditioners primarily include a housing, an indoor air circulation assembly, and an outdoor air circulation assembly. Both the indoor and outdoor air circulation assemblies are housed within the housing, and the housing is provided with indoor air inlets and outlets corresponding to the indoor air circulation assembly. The housing also includes outdoor air inlets and outlets corresponding to the outdoor air circulation assembly. Due to their small size, mobile air conditioners can be moved to different locations or rooms to adjust the air temperature there.

[0003] In related-art mobile air conditioners, a signal receiver is typically located near the air outlet of the indoor air supply module to facilitate reception of remote control signals. When the mobile air conditioner is in cooling mode, the airflow from the air outlet is low temperature, resulting in a significant temperature difference between the airflow and the signal receiver, making condensation more likely to form on the receiver. Utility Model Content

[0004] The utility model aims to solve the above technical problem, that is, to solve the problem that condensation is easily generated on a signal receiving device in a mobile air conditioner.

[0005] The utility model provides a mobile air conditioner, comprising: a shell, the interior of which defines an indoor heat exchange chamber, the shell comprising a front panel; an indoor fan, arranged in the heat exchange chamber, the indoor fan comprising a first volute facing the front panel; a mounting base, arranged in the first volute, two side ends of the mounting base opposite to each other being respectively provided with first ribs fixedly connected to the first volute; a signal receiving device, fixed in the mounting base.

[0006] When adopting the above technical solution, the mounting seat is arranged on the first volute facing the front panel to facilitate the signal receiving device in the mounting seat to receive the remote control signal, wherein the mounting seat and the first volute are connected through two first ribs, which can reduce the contact area between the mounting seat and the first volute, so as to reduce the amount of cold transferred from the first volute to the mounting seat, thereby reducing or even avoiding the generation of condensation on the mounting seat and the signal receiving device, thereby improving the safety of the signal receiving device and avoiding the risk of short circuit caused by condensation.

[0007] In an optional implementation scheme of the above mobile air conditioner, the first volute, the mounting seat and the first rib are integrally formed.

[0008] Providing the first volute, the first rib and the first rib as an integral part helps to improve the structural stability of the mounting seat.

[0009] In an optional embodiment of the mobile air conditioner, a second rib plate fixedly connected to the first volute is connected between the two first rib plates.

[0010] The provision of the second rib is beneficial for improving the stability of the connection between the mounting seat and the first volute, thereby improving the overall structural strength.

[0011] In an optional implementation scheme of the above mobile air conditioner, the mounting base is provided with a mounting groove opening toward the front panel, and the signal receiving device is fixed in the mounting groove.

[0012] By setting the opening of the mounting seat toward the front panel, that is, away from the first volute, the cold air in the first volute can be prevented from being directly transferred to the mounting slot, thereby reducing or even preventing condensation on the signal receiving device.

[0013] In an optional embodiment of the above-mentioned mobile air conditioner, the signal receiving device includes a PCB circuit board; the mounting groove has a first groove wall and a second groove wall arranged opposite to each other, a positioning member is provided between the first groove wall and the second groove wall, and the first groove wall and the second groove wall are provided with a first limiting member, wherein the PCB circuit board is clamped between the first limiting member and the positioning member.

[0014] The positioning member can be used to position the PCB, while the first limiting member can be used to restrict the PCB. This allows the PCB to be clamped, thereby enabling the positioning and installation of the signal receiving device. The simple structure and ease of operation help improve the installation efficiency of the signal receiving device.

[0015] In an optional embodiment of the mobile air conditioner, at least one outer side surface of the first limiting member is configured as a first guide side surface, and the first guide side surface is inclined toward the interior of the installation groove.

[0016] By setting the first guide side surface, the PCB circuit board can be slid between the first limiting member and the positioning member along the direction defined by the first guide side surface, which helps to improve installation efficiency.

[0017] In an optional embodiment of the above mobile air conditioner, slits are provided on both sides of the first limiting member.

[0018] By forming slits on both sides of the first limiting member, the first limiting member can have a certain degree of elasticity, so that the two first limiting members can be tilted toward or away from each other, so that the PCB circuit board can be clamped between the first limiting member and the positioning member.

[0019] In an optional embodiment of the above-mentioned mobile air conditioner, the mounting groove further has a third groove wall and a fourth groove wall arranged opposite to each other; the two ends of the PCB circuit board are respectively abutted against the inner side surfaces of the third groove wall and the fourth groove wall, and the height of the third groove wall is greater than the height of the fourth groove wall.

[0020] By making the two ends of the PCB circuit board abut against the inner side surfaces of the third groove wall and the fourth groove wall respectively, the two ends of the PCB circuit board can be limited to avoid displacement or shaking, thereby improving the stability of the signal receiving device after installation; at the same time, the height of the third groove wall is greater than the height of the fourth groove wall, so that the PCB circuit board can be installed and completely fixed or removed at the end abutting against the fourth groove wall.

[0021] In an optional implementation scheme of the above mobile air conditioner, the third slot wall is provided with a second limiting member, and the PCB circuit board is further clamped between the second limiting member and the positioning member.

[0022] By providing the second limiting member, the end portion of the PCB circuit board that abuts against the third slot wall can be located between the second limiting member and the positioning member, thereby preventing the end portion from falling out.

[0023] In an optional embodiment of the above mobile air conditioner, the side of the second limiting member facing the fourth groove wall is constructed as a second guide side, and the distance between the second guide side and the third groove wall gradually decreases from the outer end surface to the inner end surface.

[0024] By setting the second guide side surface, the end of the PCB circuit board abutting the third groove wall can slide to the bottom of the second limiting member along the direction defined by the second guide side surface, thereby improving installation efficiency.

[0044] Combine Figures 1 to 8 As shown, the utility model provides a mobile air conditioner, including a housing 100 , an indoor fan 200 , a mounting base 300 and a signal receiving device 500 .

[0045] The interior of the housing 100 defines an indoor heat exchange chamber 101 and includes a front panel 110. An indoor fan 200 is disposed within the indoor heat exchange chamber and includes a first volute 210 facing the front panel 110. A mounting base 300 is disposed within the first volute 210, with first ribs 410 fixedly connected to the first volute 210 at two opposing sides of the mounting base 300. A signal receiving device 500 is secured within the mounting base 300.

[0046] Optionally, the housing 100 defines a hollow interior. A central partition 102 is provided within the hollow interior, dividing the hollow interior into an indoor heat exchange chamber 101 and an outdoor heat exchange chamber 103, which are located vertically and independently of each other. Correspondingly, the housing 100 is provided with an indoor air inlet 104 and an indoor air outlet 105. Within the indoor heat exchange chamber 101, an indoor heat exchanger 600 and an indoor fan 200 are provided. The indoor heat exchanger 600 and the indoor fan 200 are sequentially arranged on the central partition 102 along the air flow path from the indoor air inlet 104 to the indoor air outlet 105. Driven by the indoor fan 200, indoor air enters the indoor heat exchange chamber 101 through the indoor air inlet 104, exchanges heat with the indoor heat exchanger 600, and then, driven by the indoor fan 200, enters the indoor environment through the indoor air outlet 105, thereby regulating the indoor temperature.

[0047] Air entering the indoor heat exchange chamber 101 flows through the indoor heat exchanger 600 and then toward the indoor fan 200. The indoor fan 200 includes a first volute 210 and a second volute 220 that are interlocked. A rotor installation space is defined between the first volute 210 and the second volute 220, and the indoor fan's rotor is disposed within this rotor installation space. The first volute 210 is positioned toward the front panel 110 of the outer casing 100. The second volute 220 includes a vertically arranged air inlet plate and an annular housing. The air inlet plate is provided with an airflow inlet for the indoor fan 200. The annular housing is interlocked with the first volute 210. The annular housing and the first volute 210 are both provided with an airflow outlet for the indoor fan 200, wherein the airflow outlet is correspondingly arranged and connected to the indoor air outlet 105. When the rotor rotates, air is drawn in from the indoor air inlet 104 to the indoor air outlet 105, thereby circulating the indoor air and regulating the indoor air temperature.

[0048] Optionally, the housing 100 further includes a left panel, a right panel, and a top panel 120 connected to the front panel 110 , and the indoor air outlet 105 is provided on the top panel 120 .

[0049] Optionally, the indoor heat exchanger 600 and the indoor fan 200 extend in the same direction on the middle partition 102. The length of the indoor heat exchanger 600 and the indoor fan 200 is in the direction from the left panel to the right panel of the housing 100. The air outlet and the indoor air outlet 105 also extend in the direction from the left panel to the right panel of the housing 100.

[0050] Optionally, a signal receiving device 500 is provided on the side of the first volute 210 facing the front panel 110 . A mounting seat 300 is provided on the first volute 210 , and the signal receiving device 500 is clamped in the mounting seat 300 .

[0051] Optionally, the mounting base 300 extends along the length of the indoor fan 200. Alternatively, the mounting base 300 extends along the height of the indoor fan 200. When the mobile air conditioner is in cooling mode, the air flowing into the indoor fan 200 is low-temperature air, thereby lowering the temperature of the first volute 210. However, the temperature of the signal receiving device 500 is typically higher than that of the first volute 210, resulting in a large amount of condensation on the mounting base 300. To reduce or even eliminate condensation on the mounting base 300, the contact area between the mounting base 300 and the first volute 210 can be reduced.

[0052] Therefore, two opposite side ends of the mounting seat 300 are respectively provided with first ribs 410 , and the first ribs 410 are fixedly connected to the first volute 210 .

[0053] Optionally, the two first ribs 410 are respectively provided at two side ends in the length direction of the mounting seat 300 to reduce the contact area with the first volute 210 .

[0054] Alternatively, a plurality of connecting ribs are provided at two side ends in the length direction of the mounting seat 300 , and the plurality of connecting ribs are arranged at intervals along the width direction of the mounting seat.

[0055] Alternatively, the two first ribs 410 are respectively disposed at two side ends of the mounting base 300 in the width direction.

[0056] When adopting the above technical solution, the mounting base 300 is arranged on the first volute 210 facing the front panel 110, so that the signal receiving device 500 in the mounting base 300 can receive the remote control signal, wherein the mounting base 300 and the first volute 210 are connected through two first ribs 410, which can reduce the contact area between the mounting base 300 and the first volute 210, so as to reduce the amount of cold transferred from the first volute 210 to the mounting base 300, thereby reducing or even avoiding the generation of condensation on the mounting base 300 and the signal receiving device 500, thereby improving the safety of the signal receiving device 500 and avoiding the risk of short circuit caused by condensation.

[0057] In an optional embodiment of the mobile air conditioner, the first volute 210, the mounting base 300 and the first rib 410 are integrally formed.

[0058] By forming the first volute 210 , the mounting seat 300 and the first rib 410 into one piece, the structural stability of the mounting seat 300 is improved.

[0059] Alternatively, the first volute 210 and the first rib 410 are integrally formed, and the first rib 410 and the mounting seat 300 are fixedly connected by gluing, welding, or the like.

[0060] Alternatively, the mounting seat 300 and the first rib plate 410 are integrally formed, and the first rib plate 410 and the first volute 210 are fixedly connected by gluing, welding or other methods.

[0061] Alternatively, the first rib 410 is fixedly connected to the mounting seat 300 by gluing, welding or the like; the first rib 410 is fixedly connected to the first volute 210 by gluing, welding or other means.

[0062] In an optional embodiment of the mobile air conditioner, a second rib plate 420 fixedly connected to the first volute 210 is connected between the two first rib plates 410 .

[0063] The provision of the second rib 420 is beneficial for improving the stability of the connection between the mounting seat 300 and the first volute 210 , thereby improving the overall structural strength.

[0064] Optionally, a first step is configured at the end of the first volute 210 near the indoor air outlet 105. To be as close as possible to the indoor air outlet 105, a second rib 420 is disposed on the first step, and the second rib 420 is configured with a second step that matches the first step. The first and second steps abut against each other.

[0065] Optionally, the second rib 420 is fixedly connected to the mounting base 300 and extends along a direction from one first rib to another first rib.

[0066] Alternatively, a gap is provided between the second rib 420 and the mounting seat 300 .

[0067] Alternatively, the second rib 420 is not provided.

[0068] Optionally, the second rib 420, the first volute 210 and the mounting seat 300 are integrally formed.

[0069] Optionally, the second rib 420 , the first volute 210 and the mounting seat 300 are not formed in one piece.

[0070] Optionally, a third rib 430 is provided between the two first ribs 410 , and the third rib is parallel to the first rib 410 , or an angle is formed between the third rib 430 and the first rib 410 .

[0071] Alternatively, the third rib 430 is not provided.

[0072] In the optional embodiment of the mobile air conditioner, the mounting base 300 is provided with a mounting groove 301 opening toward the front panel 110 , and the signal receiving device 500 is fixed in the mounting groove 301 .

[0073] By setting the opening of the mounting base 300 to face the front panel 110, that is, away from the first volute 210, the cold air in the first volute 210 can be prevented from being directly transferred to the mounting groove 301, thereby further reducing or even preventing condensation of the signal receiving device 500.

[0074] A gap is formed between the mounting base 300 and the front panel 110 to prevent collision between the signal receiving device 500 and the front panel 110 , thereby improving the safety of the signal receiving device 500 .

[0075] Alternatively, the opening of the mounting groove 301 faces the top panel 120 of the housing 100 .

[0076] There is a gap between the mounting base 300 and the front panel 110, or the mounting base 300 can abut against the front panel 110. After the signal receiving device 500 is installed, there is a gap between the top panel 120 to avoid collision between the signal receiving device 500 and the top panel 120.

[0077] In an optional embodiment of the above-mentioned mobile air conditioner, the signal receiving device 500 includes a PCB circuit board 510; the mounting groove 301 has a first groove wall 310 and a second groove wall 320 arranged opposite to each other, a positioning member 330 is provided between the first groove wall 310 and the second groove wall 320, and the first groove wall 310 and the second groove wall 320 are provided with a first limiting member 341, wherein the PCB circuit board 510 is clamped between the first limiting member 341 and the positioning member 330.

[0078] The positioning member 330 can be used to position the PCB 510, while the first stopper 341 can be used to restrict the PCB 510. This allows the PCB 510 to be clamped, thereby enabling the positioning and installation of the signal receiving device 500. This simple structure is easy to operate, and helps improve the installation efficiency of the signal receiving device 500.

[0079] Optionally, a plurality of positioning members 330 are spaced apart along the extension direction of the mounting base 300. The positioning members 330 abut against the lower side of the PCB 510. The height of the positioning members 330 limits the installation depth of the PCB 510 within the mounting slot 301. Furthermore, the first slot wall 310 and the second slot wall 320 are provided with a first limiting member 341. The PCB 510 is secured between the first limiting member 341 and the positioning members 330. That is, the first limiting member 341 abuts against the upper side of the PCB 510, thereby clamping the PCB 510 and enabling installation of the signal receiving device 500.

[0080] Optionally, the first position-limiting member 341 is a position-limiting buckle. Alternatively, the first position-limiting member 341 is a position-limiting protrusion.

[0081] In an optional embodiment of the mobile air conditioner, the outer side surface of at least one first limiting member 341 is configured as a first guide side surface 3411 , and the first guide side surface 3411 is inclined toward the interior of the installation groove 301 .

[0082] By setting the first guide side surface 3411, the PCB circuit board 510 can slide along the direction defined by the first guide side surface 3411 to between the first limiting member 341 and the positioning member 330, which helps to improve installation efficiency.

[0083] The outer side surface of the first limiting member 341 is the side surface facing away from the interior of the installation slot 301 .

[0084] Alternatively, the first guide side surface 3411 is not provided.

[0085] In an optional embodiment of the above mobile air conditioner, slits are provided on both sides of the first limiting member 341 .

[0086] By forming slits on both sides of the first limiter 341, the first limiter 341 can have a certain elasticity, so that the two first limiters 341 can tilt toward or away from each other, so that the PCB circuit board 510 can be stuck between the first limiter 341 and the positioning member 330.

[0087] In addition, by providing the slits, condensation generated inside the mounting groove 301 can drip downward through the slits toward the middle partition plate 102, thereby reducing the risk of short circuit of the signal receiving device.

[0088] Alternatively, a slit is provided on one of the two sides of the first position-limiting member 341. Alternatively, no slit is provided on the two sides of the first position-limiting member 341.

[0089] In an optional embodiment of the above-mentioned mobile air conditioner, the mounting groove 301 further has a third groove wall 350 and a fourth groove wall 360 arranged opposite to each other; the two ends of the PCB circuit board 510 are respectively abutted against the inner side surfaces of the third groove wall 350 and the fourth groove wall 360, and the height of the third groove wall 350 is greater than the height of the fourth groove wall 360.

[0090] By making the two ends of the PCB circuit board 510 abut against the inner side surfaces of the third groove wall 350 and the fourth groove wall 360 respectively, the two ends of the PCB circuit board 510 can be limited to avoid displacement or shaking, thereby improving the stability of the signal receiving device 500 after installation; at the same time, the height of the third groove wall 350 is greater than the height of the fourth groove wall 360, which can facilitate the installation and complete fixation or removal of the PCB circuit board 510 at the end abutting against the fourth groove wall 360.

[0091] Specifically, the side end of the PCB circuit board 510 abutting the third slot wall 350 is defined as the moving-in end, and the side end of the PCB circuit board 510 abutting the fourth slot wall 360 is defined as the moving-out end. When installing the signal receiving device, the PCB circuit board 510 can be placed at the end of the first limiter 341 and pressed toward the inside of the installation slot 301 to slide the PCB circuit board 510 between the first limiter 341 and the positioning member 330. At this time, the PCB circuit board 510 abuts the end of the fourth slot wall 360. The moving-out end is pushed toward the direction of the third slot wall 350 so that the moving-in end moves and abuts the third slot wall 350, and then the moving-out end abuts the fourth slot wall 360. When disassembling the signal receiving device, the moving-out end can be clamped and force applied upwards so that it is higher than the fourth slot wall 360, and then the signal receiving device can be moved in a direction away from the third slot wall 350. The force is applied to cause the two first limiting members 341 to produce slight elastic deformation in directions away from each other, so that the PCB circuit board is separated from the mounting base 300.

[0092] Optionally, the positioning members 330 include two, which are respectively provided on the third slot wall 350 and the fourth slot wall 360. Furthermore, one or more positioning members are arranged between the third slot wall 350 and the fourth slot wall 360 at intervals.

[0093] Alternatively, a plurality of positioning members 330 are disposed at intervals between the third slot wall 350 and the fourth slot wall 360 .

[0094] Optionally, the positioning member 330 is a positioning plate or a positioning rib.

[0095] Optionally, the ends of the fourth slot wall 360 are connected to the first slot wall 310 and the second slot wall 320 respectively via two positioning members 330. The positioning members 330 are bent positioning plates and are shorter than the fourth slot wall 360. This allows a gap to be formed between the fourth slot wall 360 and the first and second slot walls 310, 320, facilitating access to the PCB 510.

[0096] Optionally, near the third groove wall 350 , positioning members 330 are provided on both the first groove wall 310 and the second groove wall 320 .

[0097] Optionally, at least one positioning member 330 is provided on the third groove wall 350 .

[0098] Optionally, positioning steps are provided at the connections between the positioning member 330 and the first slot wall 310 , the second slot wall 320 , the third slot wall 350 and the fourth slot wall 360 , and the PCB circuit board 510 can be arranged on the lower step surface of the positioning steps.

[0099] In the optional embodiment of the mobile air conditioner, the third slot wall 350 is provided with a second limiting member 342 , and the PCB circuit board 510 is further fixed between the second limiting member 342 and the positioning member 330 .

[0100] By disposing the second limiting member 342 , the end portion of the PCB circuit board 510 that abuts against the third slot wall 350 can be located between the second limiting member 342 and the positioning member 330 , thereby preventing the end portion from falling out.

[0101] Specifically, after the PCB 510 is pressed and installed between the first stopper 341 and the positioning member 330, the PCB 510 abuts against the end of the fourth slot wall 360. The removal end is pushed toward the third slot wall 350, so that the insertion end abuts against the third slot wall 350 and is positioned below the second stopper 342. The removal end then abuts against the fourth slot wall 360, thereby securing the signal receiving device.

[0102] Optionally, the second limiting member 342 is fixed to the third groove wall 350 and can be configured to be in the shape of a rectangular protrusion, a semicircular protrusion, or the like.

[0103] Alternatively, the second limiting member 342 is not provided.

[0104] In the optional embodiment of the above mobile air conditioner, combined with Figure 7 、 Figure 8 As shown, the side of the second limiting member 342 facing the fourth groove wall 360 is constructed as a second guide side surface 3421 , and the distance between the second guide side surface 3421 and the third groove wall 350 gradually decreases from the outer end surface to the inner end surface of the second limiting member 342 .

[0105] By setting the second guide side surface 3421, the end of the PCB circuit board 510 abutting against the third groove wall 350, that is, the moving-in end, slides to the bottom of the second limit member 342 along the direction defined by the second guide side surface 3421, thereby improving installation efficiency.

[0106] The outer end surface of the second limiting member 342 is the side surface facing away from the bottom wall of the installation groove 301 , and the inner end surface of the second limiting member 342 is the side surface facing the bottom wall of the installation groove 301 .
