Technical Field

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

[0002] At present, whether it is a wall-mounted air conditioner or a floor-standing air conditioner, it needs to be fixedly installed in a limited position and cannot be moved. Therefore, mobile air conditioners came into being. Mobile air conditioners mainly include a casing, an indoor air flow circulation component and an outdoor air flow circulation component. Among them, the indoor air flow circulation component and the outdoor air flow circulation component are both arranged in the casing. The mobile air conditioner is very small in volume and can be moved to different positions or rooms, so as to adjust the temperature of the indoor air.

[0003] In the existing mobile air conditioner, a water receiving tray is arranged in the casing. The indoor air flow circulation component is arranged on the water receiving tray and includes a fan component and a heat exchanger. The fan component and the heat exchanger are arranged in sequence along the air flow direction, and both the fan component and the heat exchanger are fixedly connected to the water receiving tray through a plurality of screws. In this way, the heat exchanger is prone to be misaligned with the fan component during installation, resulting in inconvenient installation and positioning, causing air flow loss and reducing the heat exchange efficiency. Summary of the Utility Model

[0004] The utility model aims to solve the above technical problems, that is, to solve the problem of inconvenient fixation and positioning of the heat exchanger and the fan component in the mobile air conditioner, avoid misalignment between the heat exchanger and the fan component, and improve the heat exchange efficiency.

[0005] The utility model provides a mobile air conditioner, including: a housing, which defines an indoor heat exchange chamber inside, and the housing is provided with an indoor air inlet and an indoor air outlet; an indoor heat exchanger, arranged in the indoor heat exchange chamber, including a heat exchanger main body, a first end plate and a second end plate, the first end plate and the second end plate are oppositely arranged at two opposite side ends of the heat exchanger main body; an indoor fan, arranged in the indoor heat exchange chamber, and the indoor heat exchanger and the indoor fan are located on the air flow path between the indoor air inlet and the indoor air outlet. The indoor fan includes a first volute facing the indoor heat exchanger; a first side plate and a second side plate, which are respectively arranged along the vertical direction at the first side end and the second side end of the first volute and extend towards the indoor heat exchanger. The first side plate is clamped with the first end plate, and the second side plate is connected with the second end plate through a connecting piece.

[0006] In the case of adopting the above technical solution, by clamping the first end plate of the indoor heat exchanger to the first side plate, the positioning of the first end plate can be initially realized, so as to realize the positioning of the side of the heat exchanger main body connected to the first end plate. By connecting the second end plate to the second side plate through a connecting piece, the fixing of the second end plate can be further realized, so that the fixing of the side of the heat exchanger main body connected to the second end plate can be realized. In this way, the accurate docking of the indoor heat exchanger and the indoor fan can be realized, the dislocation during the installation of the indoor heat exchanger can be avoided, the air flow loss can be reduced, and the heat exchange efficiency of the mobile air conditioner can be improved.

[0007] In an alternative embodiment of the above mobile air conditioner, a positioning rib extending vertically is provided on the outer surface of the first side plate. The positioning rib and the first side plate jointly define a card slot facing the direction of the second side plate. Both the upper end and the lower end of the card slot are open, so that the first end plate can be inserted into the card slot.

[0008] By forming a card slot facing the second side plate between the positioning rib and the first side plate, the clamping installation of the first end plate can be realized, which is convenient for quickly positioning and installing the first end plate and can improve the installation efficiency.

[0009] In an alternative embodiment of the above mobile air conditioner, a flanging extending in a direction away from the heat exchanger main body is provided at the side end of the first end plate facing the indoor fan, and the flanging is inserted into the card slot.

[0010] The flanging is bent and connected to the first end plate. In this way, the flanging can form a tight clamping fit with the card slot on the positioning rib, improving the connection strength and connection stability between the first end plate and the first side plate.

[0011] In an alternative embodiment of the above mobile air conditioner, the width of the card slot is 3 to 10 times the thickness of the first end plate.

[0012] With such a setting, it can not only ensure that the first end plate can be smoothly inserted into the card slot, but also avoid relatively violent shaking of the first end plate in the card slot, and can ensure the stability of the indoor heat exchanger after installation.

[0013] In an alternative embodiment of the above mobile air conditioner, the positioning rib includes: a first rib strip fixedly connected to the first side plate; a second rib strip bent and connected to the first rib strip and arranged opposite to the first side plate.

[0014] Through the arrangement of the first rib strip and the second rib strip connected by bending, a card slot facing the second side plate can be enclosed between them and the first side plate, that is, a card slot is formed through a bending structure and forms a fit with the flanging, which can further improve the connection strength and connection stability between the first end plate and the first side plate.

[0015] In the alternative implementation of the above-mentioned mobile air conditioner, the positioning rib further includes: a limiting block, which is arranged vertically on the second rib and forms a gap with the first side plate, and the first end plate can pass through the gap.

[0016] By arranging the limiting block, it can contact the surface of the first end plate to increase the friction force, thereby avoiding the loosening and shaking of the first end plate.

[0017] In the alternative implementation of the above-mentioned mobile air conditioner, the distance between the surface of the limiting block and the first side plate is 1 to 2 times the thickness of the first end plate.

[0018] With such an arrangement, the stability of the installation of the first end plate can be ensured.

[0019] In the alternative implementation of the above-mentioned mobile air conditioner, the bottom end of the second rib inclines outward in a direction away from the first side plate to form a guiding inlet between it and the first side plate.

[0020] By making the bottom end of the second rib incline outward in a direction away from the first side plate, a guiding inlet that is flared relative to the card slot is formed, which can play a guiding role for the first end plate and is beneficial to the insertion of the first end plate into the card slot along the guiding inlet, improving the installation efficiency.

[0021] In the alternative implementation of the above-mentioned mobile air conditioner, a plurality of first screw holes are arranged at intervals vertically on the second end plate, and second screw holes corresponding to the first screw holes are arranged on the second side plate.

[0022] Through the cooperation of the first screw holes, the second screw holes and the screws, the fixed connection between the second end plate and the second side plate can be realized.

[0023] In the alternative implementation of the above-mentioned mobile air conditioner, both the first side plate and the second side plate are integrally formed with the first volute.

[0024] By integrally forming the first side plate and the second side plate with the first volute, the structural stability of the first volute can be improved, and further the stability of the clamping and fixing of the first end plate can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Combined with Figures 1 to 8 As shown, the present utility model provides a mobile air conditioner, which includes a housing 100, an indoor heat exchanger 200, an indoor fan 300, a first side plate 410, and a second side plate 420.

[0043] An indoor heat exchange cavity 110 is defined inside the housing 100, and an indoor air inlet 111 and an indoor air outlet 112 are provided on the housing. The indoor heat exchanger 200 is arranged in the indoor heat exchange cavity 110 and includes a heat exchanger main body 210, a first end plate 220, and a second end plate 230. The first end plate 220 and the second end plate 230 are oppositely arranged at two opposite side ends of the heat exchanger main body 210. The indoor fan 300 is arranged in the indoor heat exchange cavity 110, and the indoor heat exchanger 200 and the indoor fan 300 are successively located on the air flow path between the indoor air inlet 111 and the indoor air outlet 112. The indoor fan 300 includes a first volute 310 facing the indoor heat exchanger 200. The first side plate 410 and the second side plate 420 are respectively arranged vertically at the first side end and the second side end of the first volute 310 and extend towards the indoor heat exchanger 200. The first side plate 410 is snap-connected to the first end plate 220, and the second side plate 420 is connected to the second end plate 230 by a connecting member.

[0044] Optionally, the housing 100 includes a front shell 101 and a rear shell 102 that are detachably connected, and the front shell 101 and the rear shell 102 jointly define a hollow inner cavity. Among them, a middle partition 120 is provided inside the housing 100, and the middle partition 120 divides the hollow inner cavity into an indoor heat exchange cavity 110 and an outdoor heat exchange cavity 130 that are vertically distributed and independent of each other. Correspondingly, an indoor air inlet 111 and an indoor air outlet 112 are provided on the housing 100, and the indoor heat exchanger 200 and the indoor fan 300 are sequentially arranged on the middle partition 120 along the air flow path in the indoor heat exchange cavity 110. The indoor air is driven by the indoor fan 300 to enter the indoor heat exchange cavity 110 through the indoor air inlet, exchanges heat with the indoor heat exchanger 200, and then enters the indoor environment through the indoor air outlet 112 under the drive of the indoor fan 300 to achieve temperature adjustment of the indoor environment.

[0045] Further, the indoor air inlet 111 can be provided on the rear shell 102, and the indoor air outlet 112 can be provided on the front shell 101.

[0046] Optionally, the indoor heat exchanger 200 includes a heat exchanger main body 210, a first end plate 220, and a second end plate 230. The length direction of the heat exchanger main body 210 extends along the first direction, and the first end plate 220 and the second end plate 230 are respectively arranged at both ends in the length direction of the heat exchanger main body 210 to improve the structural stability of the heat exchanger main body 210.

[0047] Among them, the direction from the front side wall to the rear side wall of the housing 100 is the width direction of the housing 100, and the direction from the left side wall to the right side wall of the housing 100 is the length direction of the housing 100. The first direction can be the length direction of the housing 100 or the width direction of the housing 100.

[0048] Further, the indoor fan 300 includes a first volute 310. The first volute 310 has a mounting plate 311 extending vertically and a first volute main body 312. The first volute main body 312 is fixed on the side of the mounting plate 311 facing away from the indoor heat exchanger 200. An air flow inlet corresponding to the first volute main body 312 is provided on the mounting plate 311, and the air that has exchanged heat with the indoor heat exchanger 200 enters the indoor fan 300 through the air flow inlet.

[0049] The mounting plate 311 includes a first side end and a second side end that extend vertically and are arranged oppositely, namely, the first side end and the second side end of the first volute 310. Specifically, the first side plate 410 and the second side plate 420 are respectively arranged at the first side end and the second side end and extend towards the indoor heat exchanger 200. Among them, the first side plate 410 is snap-connected to the corresponding first end plate 220, and the second side plate 420 is connected to the corresponding second end plate 230 through a connecting member. In this way, when installing the indoor heat exchanger 200 and the indoor fan 300, the first end plate 220 can be first snapped onto the first side plate 410 to achieve the positioning of this side of the heat exchanger main body 210. Further, the heat exchanger main body 210 is placed according to the set position, and then the second end plate 230 and the second side plate 420 are fixedly connected through a connecting member. Thereby, the accurate docking of the indoor heat exchanger 200 and the indoor fan 300 can be realized, the misalignment between the indoor heat exchanger 200 and the indoor fan 300 during installation can be avoided, the air flow loss can be reduced, and the heat exchange efficiency of the mobile air conditioner can be improved.

[0050] Optionally, the connecting member is a screw. Alternatively, the connecting member is a rivet.

[0051] In the case of adopting the above technical solution, by snap-connecting the first end plate of the indoor heat exchanger to the first side plate, the positioning of the first end plate can be initially realized, so as to realize the positioning of the side of the heat exchanger main body connected to the first end plate. By screw-connecting the second end plate to the second side plate, the fixation of the second end plate can be further realized, so that the fixation of the side of the heat exchanger main body connected to the second end plate can be realized. In this way, the accurate docking of the indoor heat exchanger and the indoor fan can be realized, the misalignment during the installation of the indoor heat exchanger can be avoided, the air flow loss can be avoided, and the heat exchange efficiency of the mobile air conditioner can be improved.

[0052] In the optional implementation scheme of the above mobile air conditioner, a positioning rib 430 extending vertically is provided on the outer surface of the first side plate 410. The positioning rib 430 and the first side plate 410 jointly define a card slot 4301 facing the direction of the second side plate 420. Both the upper end and the lower end of the card slot 4301 are open, so that the first end plate 220 can be inserted into the card slot 4301.

[0053] By forming the card slot 4301 facing the second side plate 420 between the positioning rib 430 and the first side plate 410, the snap-in installation of the first end plate 220 can be realized, which is convenient for realizing the rapid positioning and installation of the first end plate 220 and can improve the installation efficiency.

[0054] Optionally, the card slot 4301 has an opening facing the second side plate 420 to facilitate the insertion and clamping of the first end plate 220 into the card slot 4301, thereby improving the installation efficiency. Further, the upper end of the card slot 4301 is open so that the top end of the first end plate 220 can slide upward along the card slot 4301 until the top end of the first end plate 220 is flush with the top end of the first side plate 410, and the lower ends of the card slot 4301 are all open so that the first end plate 220 can slide into the card slot 4301 through the lower opening. During installation, the indoor heat exchanger 300 can be fixed first, and then the indoor fan 300 can be installed. In this way, when installing the indoor fan 300 vertically downward, the lower opening of the card slot 4301 can be aligned with the first end plate 220, and the indoor fan 300 can be pushed downward.

[0055] Optionally, the length of the card slot 4301 is equal to the height of the first end plate 220. Alternatively, the length of the card slot 4301 is less than the height of the first end plate 220.

[0056] Alternatively, a stop piece is provided at the top end of the first side plate 410 to limit the upward movement distance of the first end plate 220, so as to improve the installation accuracy.

[0057] Alternatively, the stop piece may not be provided at the top end of the first side plate 410.

[0058] In this solution, the outer surface of the first side plate 410 refers to the surface of the first side plate 410 facing the indoor heat exchanger 200.

[0059] In the alternative implementation of the above-mentioned mobile air conditioner, as shown in Figure 4 a flanging 221 that bends and extends in a direction away from the heat exchanger main body 210 is provided at the side end of the first end plate 220 facing the indoor fan 300, and the flanging 221 is inserted into the card slot 4301.

[0060] The flanging 221 is bent and connected to the first end plate 220. In this way, the flanging 221 can form a tight clamping fit with the card slot 4301 on the positioning rib 430, so as to improve the connection strength and connection stability between the first end plate 220 and the first side plate 410.

[0061] Specifically, by providing the flanging 221, the contact area between the first end plate 220 and the card slot 4301 can be increased, and the connection stability between the two can be improved. The bent flanging 221 is closely fitted with the card slot 4301, which can significantly increase the strength of the connection part and make the overall structure more stable, so as to effectively resist external impacts and vibrations.

[0062] Alternatively, the flanging 221 is not provided, and the opening of the card slot is set to face the heat exchanger main body 210.

[0063] In the optional implementation of the above-mentioned mobile air conditioner, the width of the card slot 4301 is 3 to 10 times the thickness of the first end plate 220.

[0064] With such a setting, it can not only ensure that the first end plate 220 can be smoothly inserted into the card slot 4301, but also prevent the first end plate 220 from shaking violently in the card slot 4301, and can ensure the stability of the heat exchanger main body 210 after installation.

[0065] In the optional implementation of the above-mentioned mobile air conditioner, as shown in Figure 6 、 Figure 7 shown, the positioning rib 430 includes a first rib 431 and a second rib 432. The first rib 431 is fixedly connected to the first side plate 410, and the second rib 432 is bent and connected to the first rib 431 and is arranged opposite to the first side plate 410.

[0066] Through the arrangement of the first rib 431 and the second rib 432 connected by bending, a card slot 4301 with an opening facing the second side plate 420 can be defined between them and the first side plate 410, that is, the card slot 4301 is formed by a bending structure. In this way, the card slot 4301 cooperates with the bent flanging 221, which can further improve the connection strength and connection stability between the first end plate 220 and the first side plate 410.

[0067] Optionally, the positioning rib 430 is integrally formed with the first side plate 410. Alternatively, the positioning rib 430 is fixedly connected to the first side plate 410 by connection methods such as pasting, welding, and screw connection.

[0068] Alternatively, a plurality of first ribs are arranged at intervals in the vertical direction, and the second rib 420 is arranged in the vertical direction and fixedly connected to the plurality of first ribs.

[0069] Alternatively, only one rib extending in the vertical direction is provided for the positioning rib, and a card slot is opened on the side surface of the positioning rib facing the second side plate 420.

[0070] In the optional implementation of the above-mentioned mobile air conditioner, as shown in Figure 6 、 Figure 7 shown, the positioning rib 430 further includes a limiting block 433. The limiting block 433 is arranged vertically on the second rib 432 and forms a gap with the first side plate 410, and the gap allows the first end plate 220 to pass through.

[0071] Through the setting of the limiting block 433, it can contact the surface of the first end plate 220 to increase the friction force, thereby preventing the loosening and shaking of the first end plate 220.

[0072] Optionally, one limiting block 433 is provided in the vertical direction, or a plurality of limiting blocks are arranged at intervals in the vertical direction.

[0073] Optionally, the surface of the limiting block 433 facing the first side plate 410 is provided with small protrusions to increase the friction force. Alternatively, small protrusions may not be provided on the surface of the limiting block 433 facing the first side plate 410.

[0074] Optionally, the vertical cross-section of the limiting block 433 can be rectangular, square, trapezoidal, semi-circular, etc. Among them, the right angle of the limiting block 433 facing the first side plate 410 is provided with a chamfer to avoid scratching the first end plate 220.

[0075] Alternatively, the limiting block 433 may not be provided.

[0076] In the optional implementation of the above-mentioned mobile air conditioner, the distance between the surface of the limiting block 433 and the first side plate 410 is 1 to 2 times the thickness of the first end plate.

[0077] With such a setting, the stability of the installation of the first end plate 220 can be ensured. That is, while ensuring that the first end plate 220 can pass through, the clamping of the first end plate 220 is ensured.

[0078] In the optional implementation of the above-mentioned mobile air conditioner, in combination Figure 6 、 Figure 8 As shown, the bottom end of the second rib 432 is inclined outward in a direction away from the first side plate 410 to form an inlet 4300 between it and the first side plate 410.

[0079] By making the bottom end of the second rib 432 inclined outward in a direction away from the first side plate 410, an inlet 4300 that is flared relative to the card slot 4301 is formed, which can play a guiding role in the installation of the first end plate 220, facilitating the insertion of the first end plate 220 into the card slot 4301 along the inlet 4300 and improving the installation efficiency.

[0080] During the installation process, the indoor heat exchanger 200 can be first placed on the middle partition, and the indoor fan 300 is installed vertically downward from above one side of the indoor heat exchanger 200. The inlet 4300 is aligned with the top end of the first end plate 220, and the indoor fan 300 is pushed downward to gradually slide the first end plate 220 into the card slot 4301.

[0081] Alternatively, the second rib 432 extends vertically, and the distance from the first side plate 410 from top to bottom is the same, that is, the bottom end of the second rib 432 may not form an inlet with the first side plate 410.

[0082] In the optional implementation of the above-mentioned mobile air conditioner, a plurality of first screw holes 231 are arranged at intervals in the vertical direction on the second end plate 230, and second screw holes 421 corresponding to the first screw holes 231 are arranged on the second side plate 420.

[0083] Through the cooperation of the first screw hole 231, the second screw hole 421 and the screw, the fixed connection between the second end plate 230 and the second side plate 420 can be realized. The screw for fixing can sequentially rotate through the first screw hole 231 and the second screw hole 421 and be threadedly connected with the first screw hole 231 and the second screw hole 421, so as to realize the stable installation of the second end plate 230 and the second side plate 420.

[0084] Alternatively, a first ear portion is provided on the second end plate 230, and the first screw hole 231 is arranged on the first ear portion; correspondingly, a second ear portion corresponding to the first ear portion is provided on the second side plate 420, and the second screw hole 421 is arranged on the second ear portion.

[0085] In the alternative embodiment of the above-mentioned mobile air conditioner, both the first side plate 410 and the second side plate 420 are integrally formed with the first volute 310.

[0086] By integrally forming the first side plate 410 and the second side plate 420 with the first volute 310, the structural stability of the first volute 310 can be improved, and further the stability of the snap connection and fixation of the first end plate 220 can be improved.

[0087] Alternatively, the first side plate 410 and the first volute 310 are fixedly connected by means of gluing, welding, snap connection, etc. And / or, the second side plate 420 and the first volute 310 are fixedly connected by means of gluing, welding, snap connection, etc.

[0088] Alternatively, the structure of the first volute can be applied to an outdoor fan, the second end plate and the first end plate can be applied to an outdoor heat exchanger. Further, the first end plate of the outdoor heat exchanger is snap-connected to the first volute of the outdoor fan, and the second end plate is screw-connected to the first volute of the outdoor fan.
