[0033] like Figures 1-6 As shown, this utility model provides an indoor unit, including a base 100 and an evaporator assembly 200. The base 100 has a first fastening part 110 disposed near a first sidewall 160. The evaporator assembly 200 has a second fastening part 210, and the first fastening part 110 and the second fastening part 210 are locked together to lock the base 100 and the evaporator assembly 200 together. An operation window 161 is provided on the first sidewall 160 to allow the first fastening part 110 and the second fastening part 210 to be separated. The second fastening part 210 is configured to be inserted into the first fastening part 110 and then locked together with it.
[0034] The operation window 161 is an opening provided on the first side wall 160, which allows maintenance personnel or assemblers to insert their fingers into the indoor unit to switch the connection state between the first fastening part 110 and the second fastening part 210.
[0035] Wherein, after the second fastening part 210 is inserted into the first fastening part 110, the first fastening part 110 automatically locks and connects with the second fastening part 210, so that the base 100 and the evaporator assembly 200 are randomly locked and connected.
[0036] It should be noted that a first fastening part 110 and a second fastening part 210 may be provided on the base 100 and the evaporator assembly 200, or multiple sets of first fastening parts 110 and second fastening parts 210 may be provided. When only a first fastening part 110 and a second fastening part 210 are provided on the base 100 and the evaporator assembly 200, multiple quick-connect structures, such as a direct-insertion plug-in connection structure, are also provided between the base 100 and the evaporator assembly 200. These structures can be connected when the first fastening part 110 and the second fastening part 210 are connected, and can be separated when the first fastening part 110 and the second fastening part 210 are separated.
[0037] It is understood that the indoor unit, by setting a first fastening part 110 and a second fastening part 210 that can switch between locked connection and disconnection, and by setting the first fastening part 110 on the base 100 and the second fastening part 210 on the evaporator assembly 200, realizes the connection and disconnection of the base 100 and the evaporator assembly 200. At the same time, the first fastening part 110 is set close to the side wall of the base 100, and by setting an operation window 161 on the side wall of the base 100, the connection state of the first fastening part 110 and the second fastening part 210 can be quickly switched, realizing the rapid connection and disconnection of the first fastening part 110 and the second fastening part 210, thereby realizing the rapid connection and disconnection of the base 100 and the evaporator assembly 200.
[0038] In some embodiments, in addition to the locking connection achieved by the first fastening part 110 and the second fastening part 210, the base 100 and the evaporator assembly 200 are also connected by screws to improve the connection stability between the base 100 and the evaporator assembly 200. In this embodiment, generally only one screw is used to connect the base 100 and the evaporator assembly 200, which shortens the disassembly and installation efficiency between the base 100 and the evaporator assembly 200 and also ensures the connection efficiency between the base 100 and the evaporator assembly 200.
[0039] In some embodiments, the first fastening part 110 includes a slot 111 and an elastic buckle 112 disposed on one side of the slot 111. When the first fastening part 110 is locked to the second fastening part 210, the elastic buckle 112 is in a first position and the elastic buckle 112 is locked to the second fastening part 210.
[0040] After the elastic buckle 112 shifts from the first position toward the first sidewall 160 to the second position, the elastic buckle 112 separates from the second fastening part 210, the first fastening part 110 and the second fastening part 210 are unlocked, and the first fastening part 110 and the second fastening part 210 can be directly separated.
[0041] The user can insert their finger or other tool through the operation window 161 to adjust the position of the elastic buckle 112. When the elastic buckle 112 is not subjected to external force, it is in the first position, that is, it is in the locked position when it is not subjected to external force. When subjected to external force, such as the pulling force from the operation window 161, it is shifted toward the operation window 161 to the second position; or the pushing force when the second fastening part 210 is inserted, it is shifted toward the operation window 161 so that the second fastening part 210 can be smoothly inserted into the slot 111. After the second fastening part 210 is inserted into the slot 111, the pushing force on the elastic buckle 112 disappears, the elastic buckle 112 returns to the first position, and is locked and connected with the second fastening part 210.
[0042] When the elastic buckle 112 is connected to the second fastening part 210, the elastic buckle 112 engages with the second fastening part 210 to restrict the main body of the second fastening part 210 in the slot 111, thereby achieving a locking connection between the first fastening part 110 and the second fastening part 210.
[0043] In some embodiments, the evaporator assembly 200 is further provided with a first insertion portion 230 and a second insertion portion 240 on the side away from the second fastening portion 210, with the first insertion portion 230 and the second insertion portion 240 spaced apart. When the first fastening portion 110 is connected to the second fastening portion 210, the first insertion portion 230 and the second insertion portion 240 are then inserted and connected to the base 100; when the first fastening portion 110 is separated from the second fastening portion 210, the first insertion portion 230 and the second insertion portion 240 are then separated from the base 100.
[0044] That is, the first plug-in part 230 and the second plug-in part 240 are directly inserted into the base 100, which means that they can be plugged in and pulled out quickly, and thus quickly connected and separated as the first fastening part 110 and the second fastening part 210 are connected, ensuring that the base 100 and the evaporator assembly 200 can be quickly installed and disassembled.
[0045] The insertion method between the first insertion part 230 and the base 100 can be either inserted into the base 100 in the direction of the second fastening part 210 into the slot 111, or inserted into the base 100 in the direction opposite to the insertion direction of the second fastening part 210. The specific insertion method is related to the structure of the base 100 and is not limited here.
[0046] In some embodiments, the base 100 is provided with a first insertion hole 130 and a second insertion hole 140 spaced apart from each other. When the first fastening part 110 is connected to the second fastening part 210, the first insertion part 230 is inserted into the first insertion hole 130 and the second insertion part 240 is inserted into the second insertion hole 140. When the first fastening part 110 is separated from the second fastening part 210, the first insertion part 230 is separated from the first insertion hole 130 and the second insertion part 240 is separated from the second insertion hole 140.
[0047] The first insertion hole 130 and the second insertion hole 140 can be blind holes or through holes.
[0048] In some embodiments, the first insertion hole 130 and the second insertion hole 140 are arranged horizontally relative to each other on the base 100, and the first insertion part 230 and the second insertion part 240 are inserted in the horizontal direction. By arranging the first insertion hole 130 and the second insertion hole 140 horizontally relative to each other, the movement of the evaporator assembly 200 in the numerical direction can be restricted after the first insertion part 230 and the second insertion part 240 are inserted horizontally.
[0049] The first insertion hole 130 and the second insertion hole 140 are set relatively horizontally on the base 100, which means that the axial direction (central axis direction) of the first insertion hole 130 and the second insertion hole 140 is almost horizontal to the bottom surface of the base 100.
[0050] In other embodiments, the first insertion hole 130 and the second insertion hole 140 may also be inclined relative to the bottom surface of the base 100, that is, the angle between the axial direction (central axis direction) of the first insertion hole 130 and the second insertion hole 140 and the bottom surface of the base 100 is greater than 0° and less than 90°.
[0051] In some embodiments, a water receiving tray 300 is provided on the base 100, and the first insertion hole 130 and the second insertion hole 140 are both provided on the second side wall 310 of the water receiving tray 300.
[0052] The water receiving tray 300 includes a bottom wall and a second side wall 310 surrounding and connected to the bottom wall.
[0053] Generally, the first insertion hole 130 and the second insertion hole 140 are spaced apart on the second side wall 310.
[0054] In some embodiments, the first insertion hole 130 includes a second sidewall 310, a first crossbeam 301 spaced apart from the second sidewall 310, a first rib 302 and a second rib 303, the first rib 302 and the second rib 303 being connected between the second sidewall 310 and the first crossbeam 301, and the first rib 302, the second rib 303, the first crossbeam 301 and the second sidewall 310 enclosing to form the first insertion hole 130.
[0055] In some embodiments, the second insertion hole 140 includes a second sidewall 310, a second crossbeam 304 spaced apart from the second sidewall 310, a third rib 305 and a fourth rib 306, the third rib 305 and the fourth rib 306 connecting the second sidewall 310 and the second crossbeam 304, and the third rib 305, the fourth rib 306, the second crossbeam 304 and the second sidewall 310 enclosing to form the second insertion hole 140.
[0056] It is understandable that by setting the first insertion hole 130 and the second insertion hole 140 on the second side wall 310 of the water receiving tray 300, and by thickening the part of the second side wall 310 by setting the first insertion hole 130 and the second insertion hole 140, the impact resistance of the second side wall 310 is improved.
[0057] The first insertion part 230 and the second insertion part 240 are inserted into the first insertion hole 130 and the second insertion hole 140 respectively from the bottom upwards, so that the movement of the evaporator assembly 200 in the vertical direction can be restricted after the first insertion part 230 and the second insertion part 240 are inserted into the first insertion hole 130 and the second insertion hole 140 respectively.
[0058] In some embodiments, the two ends of the first crossbeam 301 are respectively connected to diagonal reinforcing ribs. One end of the diagonal reinforcing rib is connected to the first crossbeam 301 and the other end is connected to the second sidewall 310 to improve the structural stability of the first insertion hole 130 structure, thereby improving the impact resistance of the second sidewall 310.
[0059] In some embodiments, the two ends of the second crossbeam 304 are respectively connected to diagonal reinforcing ribs, one end of which is connected to the first crossbeam 301 and the other end is connected to the second sidewall 310, so as to improve the structural stability of the second insertion hole 140 structure and thereby improve the impact resistance of the second sidewall 310.
[0060] In some embodiments, the evaporator assembly 200 includes an evaporator body 203, a first end plate 201, and a second end plate 202. The first end plate 201 and the second end plate 202 are respectively connected to the two ends of the evaporator body 203. A second fastening part 210 is provided on the first end plate 201. When the second fastening part 210 is connected to the first fastening part 110, one end of the first end plate 201 is inserted into the base 100 and one end of the second end plate 202 is inserted into the base 100.
[0061] In some embodiments, the first end plate 201 is further provided with a first insertion portion 230, which is spaced apart from the first fastening portion. The second end plate 202 is provided with a second insertion portion 240, which is located at the end of the second end plate 202 near the water receiving tray 300.
[0062] In some embodiments, the evaporator assembly 200 is further provided with a first locking connection portion 220, and the base 100 is provided with a first locking engagement portion 120. When the first locking connection portion 220 is locked to the first locking engagement portion 120, the base 100 is locked to the evaporator assembly 200.
[0063] That is, the connection stability between the base 100 and the evaporator assembly 200 is enhanced by an additional locking structure.
[0064] In some embodiments, the first locking connecting part 220 and the first locking mating part 120 are respectively provided with corresponding screw holes, and the first locking connecting part 220 and the second locking mating part are screwed together to lock them together. That is, after the first locking connecting part 220 and the second locking mating part are mated, the screw passes through the screw holes of both to achieve screw connection between them.
[0065] In some embodiments, the first locking connection portion 220 and the first locking engagement portion 120 are plugged into each other and then locked together. That is, one of the first locking connection portion 220 and the first locking engagement portion 120 has an insertable structure (such as a protrusion) and the other has a receiving structure (such as a hole), and the two can be plugged into each other. After the two are plugged into each other, the locking connection between the two is achieved by screw connection.
[0066] In some embodiments, an air conditioner is also provided, which includes the indoor unit described above. Since the air conditioner includes at least some or all of the embodiments of the above-described indoor unit, the air conditioner has at least the beneficial effects of some or all of the above-described embodiments, which will not be elaborated here.
