Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0028] The evaporator and the chassis are mostly fixed by screws. The screw connection is safe, reliable, easy to disassemble, and the screw structure is simple. However, when the air conditioner is working, there is a lot of water in the evaporator. Since the screws play the role of fixing the evaporator, the screws and the evaporator are very close. The water in the evaporator will inevitably adhere to the screws. Over time, water will accumulate under the screws where the screws are exposed to the chassis. If this accumulated water overflows from the gaps and openings in the chassis, it will cause leakage.

[0029] In order to solve the above problems, this solution provides a structure for connecting the evaporator to the chassis, which can solve the problem of water leakage in the screw area without changing the existing simple and reliable connection method between the evaporator and the chassis.

[0030] Reference Figures 1 to 3 , Figure 1 Schematic diagram of the structure of an embodiment of the chassis 100 and the evaporator 200; the air conditioner includes an indoor unit and an outdoor unit. In one embodiment, the indoor unit and the outdoor unit can be integrated. In this case, the air conditioner is a mobile air conditioner and does not require an external exhaust pipe or outdoor unit. All components are integrated into one unit. In this embodiment, the indoor unit and the outdoor unit are connected by a flexible refrigerant pipe, and the compressor of the air conditioner can be further arranged in the indoor unit.

[0031] This makes the split-type air conditioner easy for users to install. It uses flexible refrigerant piping to connect the indoor heat exchanger of the indoor unit and the outdoor heat exchanger of the outdoor unit. Refrigerant is already injected into the refrigerant circuit before the unit leaves the factory. This allows users to install the unit themselves by simply securing the indoor and outdoor units separately, eliminating the need to assemble refrigerant piping or inject refrigerant. This simplifies installation and makes it easy for users to install the unit themselves.

[0032] Placing the compressor in the indoor air conditioner reduces the weight of the outdoor unit, making it easier for users to move the outdoor unit to a suitable installation location. This reduces installation effort and labor costs, especially in areas with high labor costs. To reduce noise, the indoor unit's compressor is also treated with noise-reducing materials, such as filling it with noise-reducing materials or installing a buffer structure to reduce the transmission of compressor vibration.

[0033] Specifically, the indoor heat exchanger is an evaporator 200 arranged on the air conditioner indoor unit, which includes an outer shell, a chassis 100 arranged in the outer shell, a compressor (not shown in the figure) arranged on the chassis 100, and the evaporator 200 arranged on the chassis 100.

[0034] The mounting portion 120 is configured as a mounting lug 121 provided on the chassis 100 . The mounting lug 121 is provided with a mounting hole 122 for the fixing member 300 to pass through. The form of the mounting lug 121 is not limited.

[0035] The evaporator 200 and the mounting lug 121 are locked together by screws. The number of screws depends on the situation and can be one, two, three, four, etc.

[0036] When the air conditioner is running, the surface temperature of the evaporator 200 drops to absorb heat from the room. When warm air contacts the cool surface of the evaporator 200, the water vapor in the air condenses into liquid water due to the drop in temperature, forming condensed water. If the temperature of the screw or the surrounding metal parts is lower than the dew point of the air, the water vapor in the air will also condense there, forming condensed water.

[0037] The screws are usually made of metal, which has good thermal conductivity. When the screws pass through the evaporator 200 and the chassis 100, they conduct the low temperature of the evaporator 200 to the parts of the chassis 100 that they contact, thereby lowering the temperature of these parts and causing water vapor in the air to condense at these parts.

[0038] In order to solve the problem that water vapor condenses due to temperature difference on the screws of the chassis 100 to form condensed water and leaks outside the air conditioner, causing water leakage, a water receiving groove 110, an installation part 120 and a surrounding groove 130 are provided on the chassis 100. The installation part 120 is connected to the indoor heat exchanger through a fixing part 300. The surrounding groove 130 at least frames the projection of the head of the fixing part 300 on the chassis 100, and the surrounding groove 130 is provided with an opening 131 connected to the water receiving groove 110.

[0039] Combine Figure 2 and Figure 3 The bottom of the evaporator 200 is suspended relative to the bottom of the water receiving trough 110, so that the condensed water of the evaporator 200 flows and drips into the water receiving trough 110; the end of the fixing member 300 is outside the water receiving trough 110, for example, the fixing member 300 is a screw or a bolt, and the bolt head is outside the groove wall of the water receiving trough 110. At this time, the mounting portion 120 is also set on the groove wall of the water receiving trough 110; in other schemes, the mounting portion 120 and the water receiving trough 110 can also be set separately.

[0040] After condensation occurs at the end of the fixing member 300, the condensed water drips onto the chassis 100 and accumulates for a long time, forming accumulated water. Because the condensed water is located outside the water receiving tank 110, it cannot be discharged through the water guide mechanism provided in the water receiving tank 110, which makes it easy for overflow to occur, causing users to mistakenly believe that the product has malfunctioned due to the long installation time.

[0041] A retaining groove 130 is provided around the fixing member 300 , and the retaining groove 130 can isolate the fixing member 300 from the surrounding environment, preventing direct air circulation, thereby reducing the possibility of condensation water forming on the fixing member 300 .

[0042] It should be noted that the retaining groove 130 at least frames the projection of the head of the fixing member 300 on the chassis 100, that is, when the head of the fixing member 300 is on the mounting portion 120, the area where the condensed water drips is framed by the retaining groove 130, which is equivalent to a fence. The accumulated water will accumulate in the retaining groove 130. In order to enable the accumulated water in the retaining groove 130 to be discharged, the retaining groove 130 is provided with an opening 131 connected to the water receiving trough 110. In this way, the condensed water generated on the fixing member 300 due to temperature differences can be collected.

[0043] The function of the enclosure groove 130 is to ensure that the condensed water does not spread at will, but is guided to a concentrated area, that is, the accumulated water accumulates in the enclosure groove 130, and the opening 131 of the enclosure groove 130 is connected to the water receiving area 111, so that the accumulated water can flow out through the opening 131 after accumulating to a certain extent; the setting of the enclosure groove 130 also avoids the possibility of accumulated water leaking from other locations, such as from gaps.

[0044] Furthermore, in order to facilitate the outflow of accumulated water, the bottom of the enclosure groove 130 is tilted downward toward the opening 131 .

[0045] A water guide slope is provided at the bottom of the enclosure groove 130, which is inclined downward toward the opening 131 to facilitate the outflow of accumulated water. Under the action of gravity, the water guide slope enables the collected condensed water to flow along the slope and eventually flow into the water receiving area 111 of the air-conditioning system through the opening 131.

[0046] In this embodiment, the chassis 100 is divided into a first area and a second area along the left-right direction. The first area is for installing the compressor. Vibration-damping material can be set in the first area to reduce the vibration noise of the compressor; the evaporator 200 is arranged in the second area (the second area can also be divided into a water receiving area 111 and a water storage area 112); in order to facilitate the fixation of the evaporator 200 to the chassis 100, an installation groove is formed on the chassis 100 along the first direction in the installation area, and the evaporator 200 is arranged in the installation groove.

[0047] Specifically, the water receiving tank 110 includes a water receiving area 111 located at the bottom of the indoor evaporator 200, and a water storage area 112 connected to the water receiving area 111. The enclosure tank 130 is adjacent to the water receiving area 111, and the opening 131 of the enclosure tank 130 is connected to the water receiving area 111. The water storage area 112 is lower than the water receiving area 111.

[0048] A support rib 101 is provided in the mounting groove. The mounting groove is formed by two mounting plates extending side by side along the first direction. The two ends of the mounting groove in the extension direction (first direction) are open, and the evaporator 200 is equivalent to being inserted into the mounting groove; the evaporator 200 is fixed by passing through the mounting groove through the fixing member 300, and the lower end of the evaporator 200 abuts against the support rib 101.

[0049] The water storage area 112 is located on the side of the water receiving area 111 away from the retaining groove 130. For the water receiving area 111 at the bottom of the indoor-side evaporator 200, in order to facilitate the drainage of water, a drain hole or a drainage pipe is provided in the water storage area 112 so as to automatically drain when the water volume reaches a certain level and avoid overflow. In some solutions, the water storage area 112 can be separated from the water receiving tray to facilitate the cleaning of accumulated water; in some solutions, a drainage mechanism is also provided in the water storage area to drain the accumulated water in the water storage area 112 and avoid the trouble of manual cleaning.

[0050] Thus, through the above optimization measures, the problem of condensate leakage caused by temperature difference can be reduced, thereby improving the overall performance of the air conditioner and user satisfaction.

[0051] The plurality of support ribs 101 include a first support rib 102 provided on the side of the water receiving area 111 away from the water storage area 112, and the groove wall of the retaining groove 130 includes a part of the first support rib 102.

[0052] To facilitate the collection of condensate, the bottom of the retaining groove 130 is higher than the bottom of the water receiving area 111, so that the condensate generated by the evaporator 200 can flow through the installation groove to the water receiving area 111.

[0053] To firmly fix the evaporator 200 to the installation groove, the groove wall of the installation groove is provided with an installation portion 120, and the fixing member 300 is connected to the installation portion 120 to fix the evaporator 200. To prevent the condensate of the fixing member 300 from leaking out, the part of the fixing member 300 exposed outside the installation groove corresponds to the retaining groove 130.

[0054] In this embodiment, in order to isolate the fixing member 300 from the surrounding environment, the installation groove is provided with two flanges at the position where the fixing member 300 exposes the installation portion 120. The two flanges define a slotted opening. The fixing member 300 is located in the slotted opening, and the slotted opening is respectively connected to the retaining groove 130 and the second retaining groove 130. The slotted opening extends in the second direction, and the second direction is perpendicular to the chassis 100. The two ends of the slotted opening extend along the second direction to the two ends of the groove wall of the installation groove, isolating the fixing member 300 from the surrounding environment and preventing direct air circulation, thereby reducing the possibility of condensate forming on the fixing member 300. In other embodiments, the installation portion 120 is a rib, or a reinforcing plate, etc.

[0055] In the cross-section perpendicular to the second direction, the cross-section of the slotted opening is like "冂", and the fixing member 300 is located at the horizontal pen of "冂", that is, on the groove wall of the installation groove.

[0056] One end of the retaining groove 130 is connected to the groove wall of the installation groove and extends to form a semi-enclosed structure to enclose the slotted opening. The retaining groove 130 and the groove wall of the installation groove form the retaining groove 130.

[0057] The extending height of the enclosure groove 130 in the second direction is smaller than the height of the slot, forming a gap between the two, which allows airflow to enter and drive the accumulated water to flow out from the opening 131 to avoid water accumulation.

[0058] Furthermore, since the compressor is located inside the air conditioner, wheels 103 are installed on the bottom of the unit to facilitate its movement within the room. This eliminates the need for users to carry the heavy unit; simply push it to move it. This is particularly convenient for users who frequently adjust the air conditioner's position or move it between rooms. When the air conditioner is not in use, users can simply push it to a corner or storage room, saving space.

[0059] Furthermore, the moving wheels 103 are also designed with a locking mechanism, such as a brake device, to prevent the air conditioner from sliding when it does not need to be moved.

[0060] Furthermore, considering that different floor materials (such as carpet, wooden floor, tile, etc.) have different friction forces on the moving wheel 103, which may affect the smoothness of movement, the moving wheel 103 is configured to be suitable for a variety of floor materials.

[0061] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
