Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to an air conditioner chassis structure and an air conditioner. Background Art

[0002] During the operation of the air conditioner, condensed water is usually generated on its internal structure, such as on the heat exchanger. For mobile air conditioners, the condensed water generated by its internal structure will generally be consumed internally, but when the air humidity is too high, the condensed water generation rate is usually greater than the internal consumption rate. Therefore, the excess condensed water is often discharged through the drainage structure of the air conditioner chassis structure. However, in the prior art, due to the unreasonable structural design of the chassis structure, the chassis drainage and water storage functions are not coordinated, which affects the performance of the air conditioner. Summary of the invention

[0003] The present invention is completed in view of the above-mentioned state of the prior art, and its purpose is to provide a chassis structure and an air conditioner that are more conducive to drainage and water storage and more coordinated.

[0004] To this end, one aspect of the present invention provides an air conditioner chassis structure, which includes a main water collection area, a first water storage area, a second water storage area, a water level switch area, a water trough and a drainage area; the main water collection area is respectively connected with the first water storage area, the second water storage area, the water level switch area, the water trough and the drainage area; when the chassis is placed horizontally, in the direction of gravity, the vertical heights of the main water collection area at the intersection with the water trough, the drainage area, the second water storage area and the first water storage area increase successively and are all higher than the lowest point of the bottom surface of the main water collection area; the vertical height of the main water collection area and the water level switch area at the intersection is higher than the bottom surface of the main water collection area.

[0005] The advantage of this arrangement is that it ensures that condensed water is first gathered in the main water collection area. When the water level in the main water collection area rises, the condensed water in the main water collection area flows into the water trough. When the water in the main water collection area continues to increase, the water is discharged to the drainage area, and the accumulated water is discharged in time through the drainage area to avoid excessive accumulation of condensed water in the main water collection area and cause overflow. When the water level in the main water collection area continues to rise, preventive measures need to be activated at this time. Therefore, the water in the main water collection area is directed to the second water storage area. On the one hand, the water in the main water collection area can be discharged in time, and on the other hand, the condensed water can be stored. When the water level in the main water collection area continues to rise, secondary prevention measures are required. Therefore, the water in the main water collection area is directed to the first water storage area. The height of the connection between the main water collection area and the water level switch area is at a preset position, which can ensure that water enters the water level switch area and realize water level monitoring in the chassis structure.

[0006] Optionally, a water storage groove is provided at the bottom of the water level switch area, and a dust storage groove is provided on the bottom surface of the water storage groove, and the dust storage groove is a concave structure.

[0007] Thereby, it is ensured that there is a sufficient distance between the bottom surface of the dust storage tank and the water level switch, and in the case of dust deposition for a long time, it can still be ensured that the sludge in the dust storage tank will not affect the water level switch.

[0008] Optionally, the water level switch area further includes a blocking portion, which is arranged at the water inlet of the water level switch area and is a groove structure.

[0009] As a result, the barrier ribs effectively block hair debris from entering the water level switch area, preventing the water level switch from getting stuck.

[0010] Optionally, barrier ribs are provided on the barrier portion, and the barrier ribs are used to prevent water from entering the water level switch area.

[0011] This prevents water from entering the water level switch area, allowing more water to enter the water tank earlier, thereby improving energy efficiency.

[0012] Optionally, wind shielding ribs are provided in the main water collection area, and the wind shielding ribs are provided relative to the intersection of the main water collection area and the water level switch area.

[0013] Therefore, by providing the wind shielding ribs, the air leakage at the connecting opening can be reduced without affecting the flow of water.

[0014] Optionally, there are three wind shielding ribs, and the three wind shielding ribs are distributed in a herringbone structure.

[0015] Therefore, by setting three wind-blocking ribs in a herringbone structure, the probability of air leakage is reduced without affecting the direction of water flow.

[0016] Optionally, the first water storage area is provided with a water gap and a wind shield structure, and the wind shield structure is suitable for preventing air from the evaporator direction from entering the first water storage area through the water gap in the assembled state.

[0017] In this way, the setting of the wind shield structure, on the one hand, strengthens the structural strength of the water storage area and can provide support for the evaporator in the assembled state; on the other hand, it can also prevent the air in the evaporator from entering the water storage area through the water gap, thereby preventing air leakage and improving the working efficiency of the evaporator.

[0018] Optionally, the wind shielding structure includes a first wind shielding rib plate and a second wind shielding rib plate, and projections of the first wind shielding rib plate and the second wind shielding rib plate on the plane where the water passing notch is located cover the water passing notch.

[0019] In this way, when the air in the evaporator is blown into the water storage area through the water gap, it can all be blown onto the wind shield structure, and most of it will flow back into the main water collection area under the obstruction of the first wind shield rib plate and the second wind shield rib plate, thereby reducing air leakage of the evaporator.

[0020] Optionally, the wind shield structure also includes a third wind shield rib, the first wind shield rib and the second wind shield rib are both connected to the third wind shield rib and are respectively located on both sides of the third wind shield rib; one end of the third wind shield rib extends to the water passing gap and divides the water passing gap into two parts.

[0021] In this way, the third wind shield rib divides the water passing gap into two, so that the airflow flowing from the water passing gap into the water storage area is diverted at the water passing gap, reducing the flow rate of the airflow. According to Bernoulli's principle, when the flow rate of the airflow decreases, the pressure will increase, and the resistance when the airflow flows to the water storage area will be greater, further reducing the air leakage of the evaporator; at the same time, the herringbone structure of the wind shield structure can ensure that the water storage area is not prone to shrinkage during injection molding of the chassis, thereby improving the manufacturing quality of the chassis.

[0022] Optionally, the first wind shielding rib plate, the second wind shielding rib plate and the third wind shielding rib plate are distributed in a herringbone pattern.

[0023] In this way, it can be ensured that the water storage area is not prone to shrinkage during the injection molding of the chassis, thereby improving the manufacturing quality of the chassis.

[0024] Optionally, the first water storage area has a first side wall in its length direction, and the first side wall is a V-shaped structure. The opening of the V-shaped structure faces the side of the water storage area away from the evaporator, and the water gap is arranged at the top of the V-shaped structure, which is suitable for guiding condensed water to flow along the first side wall to the water gap.

[0025] In this way, condensed water dripping into the water storage area can flow along the first side wall toward the water passing gap, so that the first side wall has a diversion effect, preventing condensed water from being retained in the water storage area, thereby improving the drainage effect of the chassis.

[0026] Optionally, the main water collection area includes a converging portion, and the converging portion is a concave structure with a low middle and high surroundings.

[0027] Therefore, by designing the converging portion as a concave structure, it is beneficial to realize the water collection function of the main water collection area.

[0028] Optionally, the converging portion includes four converging surfaces, and the four converging surfaces intersect at a converging point.

[0029] Therefore, by setting a convergence point, the condensed water in the main water collection area can be converged to the convergence point.

[0030] Optionally, the convergence point is located at a notch of the water trough.

[0031] Therefore, by setting the convergence point at the notch of the water tank, the condensed water can smoothly flow into the water tank and be discharged from the air conditioner.

[0032] Optionally, the second water storage area includes a guide bottom surface, and in the front-to-back direction, a side of the guide bottom surface adjacent to the main water collection area is lower than a side away from the main water collection area, so as to guide condensed water to flow toward the main water collection area.

[0033] Therefore, by providing a guide bottom surface inclined toward the main water collection area in the second water storage area, the condensed water in the second water storage area can flow smoothly to the main water collection area.

[0034] Optionally, the drainage area is provided with a drainage pipe, and a notch is provided at the edge of the outlet of the drainage pipe.

[0035] Therefore, by providing a notch at the outlet edge of the drain pipe, the stress of the water itself can be effectively eliminated, and shear force can be provided to the water so that it can continue to flow, thereby improving the thoroughness of water discharge in the drain pipe.

[0036] The present invention also provides an air conditioner, comprising any of the above-mentioned air conditioner chassis structures.

[0037] Optionally, the air conditioner further comprises: a water pumping mechanism, a water pumping motor area and a condenser, wherein the water pumping mechanism is suitable for pumping water in the water pumping tank onto the condenser, and the water pumping motor area is suitable for collecting water on the water pumping mechanism.

[0038] Therefore, by connecting the water level switch area with the water pumping trough, when the water in the water level switch area is discharged, it is not directly discharged from the air conditioner chassis, but the water in the water level switch area is discharged to the water pumping trough, thereby ensuring the operation of the water pumping mechanism and allowing the water in the water pumping trough to be pumped out through the water pumping mechanism; in addition, the drainage area collects the water thrown out from the rotating shaft of the water pumping motor of the water pumping mechanism.

[0039] Optionally, the water pumping motor area is only connected to the drainage area, and is suitable for directing water on the rotating shaft of the water pumping motor to the drainage area.

[0040] Thus, it is prevented that the water on the water pumping mechanism enters the main water collecting area again, and it is prevented that the condensed water is repeatedly circulated, so that the drainage is incomplete, and the water is directly discharged from the air conditioner through the drainage area.

[0041] Optionally, the water pumping motor area includes a water-conducting bottom surface. When the air conditioner chassis structure is placed horizontally, in the left and right directions, the height of the water-conducting bottom surface away from the drainage area is higher than the height of the water-conducting bottom surface close to the drainage area.

[0042] In this case, the height difference between the left and right sides of the water-guiding bottom surface can make the water-pumping motor area in an inclined state, so that the condensed water inside it flows to the lower side, that is, flows towards the drainage area. This is more conducive to the discharge of water in the water-pumping motor area, improves its discharge efficiency, and at the same time ensures the thoroughness of the discharge of the condensed water inside it.

DETAILED DESCRIPTION

[0075] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features of the embodiments may be combined with each other.

[0076] In addition, all directions or positional relationships mentioned in the embodiments of the present invention are based on the positional relationships in the drawings. The "up, down, left, right, front, and back" coordinate system appearing in the drawings is only a simplified description for the convenience of understanding the present invention, and does not imply a specific orientation that the device or element referred to must have, and should not be understood as a limitation on the present invention.

[0077] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0078] This embodiment provides an air conditioner chassis structure, such as Figure 1 and Figure 2As shown, the chassis structure includes a main water collection area 100, a first water storage area 200, a second water storage area 300, a water level switch area 500, a water trough 700 and a drainage area 400; the main water collection area 100 is respectively connected with the first water storage area 200, the second water storage area 300, the water level switch area 500, the water trough 700 and the drainage area 400; when the chassis is placed horizontally, in the direction of gravity, the vertical heights of the main water collection area 100 and the water trough 700, the drainage area 400, the second water storage area 300 and the first water storage area 200 at the intersection increase successively and are all higher than the bottom surface of the main water collection area 100; the vertical height of the main water collection area 100 and the water level switch area 500 at the intersection is higher than the bottom surface of the main water collection area 100.

[0079] It should be noted that the water level switch area 500 is equipped with a water level switch. The water level switch area 500 is used to detect the water level. When the speed of water generated is greater than the water consumed, the water level increases. When it reaches the warning position, the water level switch will send a signal to shut down the compressor and enhance the effect of water consumption to prevent water from overflowing the chassis. The water level switch floats up and down with the water level. Here, in the direction of gravity, the height of the connection between the water level switch area 500 and the main water collection area 100 is not clearly defined. The height of the connection between the water level switch area 500 and the main water collection area 100 can be greater than the vertical height of the main water collection area 100 at the intersection with the water trough 700, the drainage area 400, the second water storage area 300, and the first water storage area 200, and can also be less than the vertical height of the main water collection area 100 at the intersection with the drainage area 400, the second water storage area 300, and the first water storage area 200. It only needs to ensure the monitoring of the water level in the chassis. In the air conditioner chassis structure, water on the heat exchanger first gathers in the main water collection area 100. As the water level gradually increases, the condensed water flows into the water trough 700, the drainage area 400, the second water storage area 300, and the first water storage area 200 in sequence. When the water level rises to a certain level, the water enters the water level switch area 500, and the water level in the air conditioner chassis structure is monitored by the water level switch area 500.

[0080] The advantage of such a setting is that it ensures that the condensed water is first gathered in the main water collection area 100. When the water level in the main water collection area 100 rises, the condensed water in the main water collection area 100 flows into the water trough 700. When the water in the main water collection area continues to increase, the water is discharged to the drainage area 400, and the accumulated water is discharged in time through the drainage area 400 to avoid excessive accumulation of condensed water in the main water collection area and cause overflow. When the water level in the main water collection area 100 continues to rise, preventive measures need to be activated at this time. Therefore, the water in the main water collection area 100 is directed to the second water storage area 300. On the one hand, the water in the main water collection area can be discharged in time, and on the other hand, the condensed water can be stored. When the water level in the main water collection area 100 continues to rise, secondary prevention measures are required. Therefore, the water in the main water collection area is directed to the first water storage area 200. The height of the connection between the main water collection area 100 and the water level switch area 500 is at a preset position, which can ensure that water enters the water level switch area 500 to realize water level monitoring in the chassis structure.

[0081] like Figure 3 As shown, a water storage tank 510 is provided at the bottom of the water level switch area 500. The contour shape of the water storage tank 510 is determined according to the overall position function setting of the chassis. The contour shape of the water storage tank 510 is adapted to the regional contour of the water level switch area. The depth of the water storage tank 510 can be set according to the upper limit of the water level that the capacity of the chassis can reach. In this embodiment, the depth of the water storage tank is 14mm. When there is too much water in the chassis, the water in the water tank area will enter the water storage tank 510 through the water inlet of the water level switch area 500. The water level switch detects the water accumulation condition of the entire chassis through the water accumulation condition in the water storage tank 510. The water storage tank 510 is provided with a dust storage tank 511. Since the original intention of providing the dust storage tank 511 is to prevent the dust in the water storage tank 510 from affecting the water level switch, preferably, the dust storage tank 511 is provided directly below the water level switch so that the water level switch is completely isolated from the bottom surface of the water storage tank 510, thereby completely preventing the dust and mud in the water storage tank 510 from affecting the water level switch. The shape of the dust storage tank 511 can be set to be square, round, prismatic or other shapes. The size of the dust storage tank 511 is based on the ability to place the water level switch and does not affect the up and down floating of the water level switch. Preferably, in this embodiment, the dust storage tank 511 is set to be a circular tank to match the shape of the water level switch. The dust storage tank 511 and the water level switch are integrated from top to bottom, which conforms to traditional aesthetic concepts. A dust groove 511 is arranged on the bottom surface of the water storage groove 510. The dust groove 511 is a concave structure and is used to collect dust generated during the operation of the air conditioner. Since the bottom surface of the dust groove 511 is lower than the bottom surface of the water storage groove 510, when the water level switch is set at a conventional height, the water level switch is sufficiently far away from the bottom surface of the dust groove 511. Even if there is plaster accumulated in the dust groove 511, it is difficult to adhere to the water level switch, thereby completely avoiding the influence of the plaster on the water level switch and further ensuring the normal operation of the air conditioner.

[0082] The depth of the dust groove 511 is 5-20 mm. Preferably, the depth of the dust groove 511 is 8-15 mm, so as to ensure that there is a sufficient distance between the bottom surface of the dust groove 511 and the water level switch, and will not affect the water level monitoring function of the water level switch area. In the case of dust deposition for a long time, it can still be ensured that the mortar in the dust groove 511 will not affect the water level switch, thereby extending the maintenance time cycle, making it more convenient for users to use and enhancing the user experience.

[0083] The transverse cross-section of the dust storage groove 511 is circular, and the diameter of the dust storage groove 511 is 35-40 mm, thereby ensuring that the dust storage groove 511 can be adapted to most water level switches on the market and has high universality.

[0084] It also includes a blocking portion 512, which is arranged at the water inlet of the water level switch area 500. The blocking portion 512 is a groove structure arranged on the bottom surface of the water storage tank 510. In this embodiment, the blocking portion 512 is a square groove. The size of the blocking portion 512 is adapted to the size of the water inlet of the water level switch area 500, so that hair debris in the flowing water is deposited in the blocking portion 512, thereby blocking external hair debris from entering the water level switch area 500 and preventing the water level switch from being stuck.

[0085] The depth of the barrier portion 512 is 1-3 mm. Preferably, the depth of the barrier portion 512 is set to 1 mm. Since the accumulated water in the chassis is mostly condensed from water vapor in the air and has fewer impurities, the barrier portion with a depth of 1 mm can filter out occasional hair and impurities without affecting the strength of the main structure of the chassis.

[0086] The barrier portion 512 is provided with a barrier rib 513, which is used to prevent water from entering the water level switch area 500. In this embodiment, the barrier rib 513 is provided on the side of the barrier portion 512 close to the water level switch area 500. When the air conditioner is operating normally, there are two situations in which the drainage system consumes water. The first situation is that the air conditioner is operating normally and the water volume is small, and the water is consumed internally; the second situation is that when the air humidity is high, the water volume in the chassis is too much, causing the water level switch to alarm, and it is necessary to manually drain the water from the drain port. When the water volume in the drainage system is small, the water should enter the water-drawing area first. When the air conditioner is operating, the more water evaporates from the condenser, the more heat is taken away, which is beneficial to energy efficiency. However, the water storage capacity of the water level switch area is large, and the barrier rib 513 prevents the water in the water tank area from entering the water level switch area, allowing the water to enter the water-drawing area earlier and more, thereby improving energy efficiency.

[0087] The height of the barrier rib 513 is 1-5 mm. Preferably, the height of the barrier rib 513 is set to 3 mm, so as to ensure that the water level in the chassis flows to the water-spraying area preferentially within the control range, so that the accumulated water evaporates through the evaporator, thereby improving the energy efficiency of the air conditioner.

[0088] like Figure 4 As shown, a guide channel 514 is provided on one side of the dust storage groove 511. In the present embodiment, the guide channel 514 is a straight strip structure, the bottom surface of the guide channel 514 is flat and unobstructed, and the connection between the guide channel 514 and the dust storage groove 511 is smoothly transitioned, so as to further improve the diversion effect of the accumulated water, thereby quickly and thoroughly diverting the accumulated water in the dust storage groove 511. In other embodiments, the guide channel 514 can also be other shapes and structures, which will not be repeated here. Specifically, the dust trough 511 and the guide channel 514 are connected to each other, one end of the guide channel 514 is connected to the bottom surface of the dust trough 511, and the other end of the guide channel 514 is connected to the bottom surface of the water storage trough 510. The guide channel 514 is used to guide the water in the dust trough 511 to flow into the water storage trough 510, and then to be discharged. When the user drains the water manually, the machine needs to be tilted slightly. The guide channel 514 plays a key role in tilting and guiding the water, so that the accumulated water in the dust trough 511 can be smoothly discharged into the water storage trough 510 through the guide channel 514, avoiding the accumulation of water in the dust trough 511 and draining cleanly.

[0089] The guide channel 514 is inclined relative to the horizontal plane, and the inclination angle of the guide channel 514 is 10°-50°. Preferably, in this embodiment, the inclination angle of the guide channel is 15°-30°. Within this angle range, the inclination of the guide channel 514 is relatively gentle, which is conducive to the accumulated water in the dust storage tank 511 to flow into the water storage tank 510 through the guide channel 514, so that the guide channel 514 has a better guide effect.

[0090] The bottom surface of the water storage tank 510 is inclined relative to the horizontal plane, and the water storage tank 510 is inclined from high to low in the direction from the dust storage tank 511 to the guide channel 514. After the accumulated water in the dust storage tank 511 is guided into the water storage tank 510 through the guide channel, the accumulated water is guided again in the water storage tank 510 so that the accumulated water can be discharged from the water storage tank 510 faster and more thoroughly. The bottom surface of the water storage tank 510 has an inclination angle of 1°-10°. Preferably, the bottom surface of the water storage tank 510 has an inclination angle of 2°-5°. Within this angle range, the accumulated water in the water storage tank 510 can be better discharged and drained cleanly.

[0091] The water storage tank 510 is provided with a guide groove wall 515, which is arranged opposite to the diversion channel. When the accumulated water in the water storage tank 510 flows toward the guide groove wall 515, the guide groove wall 515 guides the accumulated water again to flow toward the water inlet of the water level switch area, thereby draining the accumulated water. The guide groove wall 515 is used to guide the water flowing out of the diversion channel 514.

[0092] like Figure 4 and Figure 5 As shown, the guide groove wall 515 includes a first guide groove wall 5151 and a second guide groove wall 5152. The first guide groove wall 5151 and the second guide groove wall 5152 are adjacently connected, and the connection is smooth, which is convenient for water diversion. The first guide groove wall 5151 is inclined relative to the horizontal plane, and the inclination angle of the first guide groove wall 5151 is 10°-60°. Preferably, in this embodiment, the inclination angle of the first guide groove wall 5151 is 30°-45°. Within this angle range, when the accumulated water in the water storage tank 510 flows toward the first guide groove wall 5151, the resistance to water is small. After the accumulated water flows toward the first guide groove wall 5151, it is diverted and flows along the second guide groove wall 5152 to the blocking part 512. The first guide groove wall 5151 and the guide channel 514 are arranged opposite to each other. In particular, the accumulated water in the dust storage groove 511 is guided out through the guide channel 514. The accumulated water flows faster. The guidance through the first guide groove wall 5151 can reduce the impact of the flowing water, so that it flows faster and better to the blocking part along the second guide groove wall 5152. One side of the second guide groove wall 5152 is connected to the first guide groove wall 5151, and the other side of the second guide groove wall 5152 is connected to the blocking part 512. The accumulated water flows directly to the blocking part 512 along the second guide groove wall 5152, and then discharged from the water storage groove 510.

[0093] The width of the guide channel 514 is 8-15 mm, and the length of the guide channel 514 is 20-40 mm. Preferably, in this embodiment, the width of the guide channel 514 is 10 mm, and the length of the guide channel 514 is 30 mm, so that the guide channel 514 and the dust accumulation groove 511 can be well adapted, and the accumulated water in the dust accumulation groove 511 can be fully discharged.

[0094] like Figure 6 As shown, an air conditioner includes an air conditioner chassis structure as described above. In order to facilitate the movement of the air conditioner, four universal wheels are provided at the bottom of the chassis. After the air conditioner chassis structure is installed on the air conditioner, when the air conditioner is in working condition, the bottom of the chassis dust storage tank cannot be too close to the ground, at least greater than 10 mm, otherwise obstacles may easily get stuck in the chassis of the air conditioner, resulting in poor walking ability of the air conditioner.

[0095] In this embodiment, Figure 1 and 2 As shown, the main water collection area 100 is higher than the second water storage area 300, and the second water storage area 300 is higher than the drainage area 400. Specifically, "higher than" is defined as: when the air conditioner is in a horizontal state as a whole, at the connection between the main water collection area 100 and the second water storage area 300, the vertical height of the main water collection area 100 at the connection is greater than the vertical height of the second water storage area 300 at the connection, that is, at the connection, the main water collection area 100 and the second water storage area 300 form a step-like structure; the vertical height of the connection between the second water storage area 300 and the main water collection area 100 is greater than the vertical height of the connection between the drainage area 400 and the main water collection area 100.

[0096] Among them, the main water collection area 100 is the main area for chassis water collection. The main water collection area 100 is located below the condenser of the air conditioner. The condensed water of the air conditioner enters the main water collection area 100 from the condenser. The main water collection area 100 receives a certain amount of condensed water and sends the condensed water that exceeds the storage amount to the water trough 700 or the drainage area 400.

[0097] At the same time, the second water storage area 300 is lower than the main water collection area 100, and the second water storage area 300 increases the water storage capacity of the chassis. When the water level of the second water storage area 300 is lower than the height of the connection between the second water storage area 300 and the main water collection area 100, the second water storage area 300 plays the role of receiving condensed water; when the water level of the second water storage area 300 is equal to or higher than the height of the main water collection area 100, the condensed water of the second water storage area 300 converges to the main water collection area 100. The heights of the main water collection area 100 and the second water storage area 300 are both greater than the height of the drainage area 400, so when the main water collection area 100 cannot consume the above condensed water through the water tank 700, this part of the condensed water is discharged through the drainage area 400. Therefore, the main water collection area 100 is arranged higher than the second water storage area 300, and the second water storage area 300 is arranged higher than the drainage area 400, and the gravity caused by the height difference is used to drive the water flow, so that the chassis can achieve fast and efficient drainage.

[0098] The air conditioner chassis structure described in the present invention, by setting the first water storage area higher than the main water collection area, can not only use the gravity caused by the height difference to drive the water flow when the water volume is small, so that the chassis can achieve rapid and efficient water collection, but also can achieve joint water storage in the main water collection area and the first water storage area when the water volume is large.

[0099] Optionally, combined Figure 7 As shown, the main water collection area 100 includes a converging portion 110, and the converging portion 110 is a concave structure with a low middle and high surroundings.

[0100] Specifically, combined Figure 8 As shown, the converging portion 110 is generally concave in shape, similar to a funnel-shaped structure, wherein: Figure 8 A schematic diagram of the area near the convergence point 112 is shown, where the convergence point 112 is the lowest point in the area and also the lowest point in the convergence portion 110, A1, A2, A3 and A4 are equal height points and also the highest points in the area, B1, B2, B3 and B4 are equal height points and also the second highest points in the area; water flows through points A and B through the convergence surface 111 and gathers at the convergence point 112, realizing the water collection function of the main water collection area 100, and then realizing the effective discharge of condensed water.

[0101] The air conditioner chassis structure described in the present invention is beneficial to realizing the water collection function of the main water collection area 100 by designing the converging part to be a concave structure.

[0102] Optionally, combined Figure 7 and Figure 8 As shown, the converging portion 110 includes four converging surfaces 111 , and the four converging surfaces 111 intersect at the converging point 112 .

[0103] Specifically, the converging portion 110 includes four converging surfaces 111, which are: a converging surface 111 composed of A1, B1, B4 and a converging point 112, a converging surface 111 composed of A2, B1, B2 and a converging point 112, a converging surface 111 composed of A3, B2, B3 and a converging point 112, and a converging surface 111 composed of A4, B3, B4 and a converging point 112. The four converging surfaces 111 form a concave structure with a low middle and high surroundings. It should be noted that in this description, the converging portion 110 is described as being composed of four converging surfaces 111, but the protection scope of the present invention is not limited to this. The converging portion 110 can be composed of a plurality of converging surfaces 111 not limited to four.

[0104] The air conditioner chassis structure of the present invention can converge the condensed water in the main water collection area to the convergence point by setting the convergence point.

[0105] Optionally, the angle γ between the converging surface 111 and the horizontal plane is in the range of 2 to 4 degrees.

[0106] Specifically, combined Figure 8As shown, taking one of the converging surfaces 111 as an example, the converging surface 111 composed of A1, B1, B4 and the converging point 112 is formed by rotating the horizontal plane upward by an angle and then rotating it to the right by an angle. During the rightward rotation process, the line connecting B4 and the converging point 112 remains fixed, and only the part of the converging surface 111 other than the line connecting B4 and the converging point 112 is rotated, so as to ensure that multiple converging surfaces 111 intersect at the converging point 112. The formation method of the remaining converging surfaces 111 is similar, and the formed converging portion 110 is a concave structure with a low middle and high surroundings; for example, the above rotation angles are all 2 degrees, and the angle γ between the formed converging surface 111 and the horizontal plane is as follows: Figure 8 As shown, Figure 8 The γ shown is represented by the angle between two extension lines. The upper extension line is extended from the line connecting the convergence point 112 and A1, and the lower extension line is extended from the line connecting the convergence point 112 and the vertical projection point of A1 on the horizontal plane. The range of the angle γ between the convergence surface 111 and the horizontal plane is limited to 2 to 4 degrees, ensuring that the water flow can be gathered at the convergence point 112 and its vicinity by gravity. At the same time, when it is necessary to discharge excess condensed water, there is no need to tilt the air conditioner at too large an angle, thereby reducing the manpower burden.

[0107] The air conditioner chassis structure of the present invention effectively ensures the effective collection and discharge process of condensed water by setting the included angle γ between the convergence surface and the horizontal plane to be in the range of 2 to 4 degrees.

[0108] Optionally, the air conditioner chassis structure further includes a water trough 700 , and the convergence point 112 is located at a notch 710 of the water trough 700 .

[0109] Combination Figure 7 and Figure 8 As shown, the convergence point 112 is located at the slot 710 of the water-pumping trough 700. An appropriate amount of condensed water flows from the convergence point 112 of the main water collection area 100 to the water-pumping trough 700 through the slot 710. The water-pumping trough 700 is connected to the water-pumping motor area 600. The condensed water is atomized by the water-pumping motor and pumped onto the condenser to evaporate the condensed water, thereby discharging the condensed water in the air conditioner. Therefore, the convergence point 112 is set at the slot 710 so that the condensed water in the main water collection area 100 can flow smoothly into the water-pumping trough 700 and be discharged from the air conditioner.

[0110] The air conditioner chassis structure of the present invention sets a convergence point at the notch of the water tank, so that condensed water can smoothly flow into the water tank and be discharged from the air conditioner.

[0111] Combination Figure 7As shown, the main water collection area 100 also includes a wind shield 120 , and the connection between the main water collection area 100 and the water level switch area 500 is arranged opposite to the wind shield 120 .

[0112] Specifically, the connection between the main water collection area 100 and the water level switch area 500 mainly serves to receive the flow of water, but air leakage may still occur here. Therefore, a wind shield 120 is arranged relative to the connection between the main water collection area 100 and the water level switch area 500 to reduce air leakage at the connection without affecting the flow of water.

[0113] Combination Figure 7 As shown, there are three wind shielding ribs 120, and the three wind shielding ribs 120 are distributed in a triangular shape. Figure 7 The T-shaped structure shown blocks the flow direction of wind through the wind blocking ribs 120 formed by the T-shaped structure, thereby limiting air leakage and reducing the probability of air leakage without affecting the flow direction of water.

[0114] Optionally, combined Fig. 9 As shown, the second water storage area 300 includes a guide bottom surface 310 . In the front-to-back direction, the side of the guide bottom surface 310 adjacent to the main water collection area 100 is lower than the side away from the main water collection area 100 , so as to guide the condensed water to flow toward the main water collection area 100 .

[0115] Specifically, the second water storage area 300 is located on the right side of the condenser. The second water storage area 300 serves to increase the water storage capacity of the chassis. Therefore, a diversion bottom surface 310 inclined toward the main water collection area 100 is set in the second water storage area 300, so that when the water level of the condensed water in the second water storage area 300 is higher than that of the main water collection area 100, the condensed water can flow to the main water collection area 100 by gravity, and then be discharged through the drainage area 400 or the water trough 700.

[0116] The air conditioner chassis structure described in the present invention provides a guide bottom surface inclined toward the main water collection area in the second water storage area, so that the condensed water in the second water storage area can be discharged smoothly when the water level is higher than the main water collection area 100.

[0117] Optionally, the angle between the guide bottom surface 310 and the horizontal plane is in the range of 2-5 degrees.

[0118] Specifically, the diversion bottom surface 310 is inclined toward the main water collection area 100. This angle range ensures that when the second water storage area 300 is used to store water, the condensed water can be effectively preserved in the second water storage area 300. At the same time, when the condensed water in the second water storage area 300 flows to the main water collection area 100, gravity is relied upon to achieve automatic flow of the condensed water, thereby effectively discharging the condensed water in the second water storage area 300.

[0119] The air conditioner chassis structure described in the present invention can effectively store and discharge the condensed water in the second water storage area by setting the inclination angle of the guide bottom surface 310 to be in the range of 2 to 5 degrees.

[0120] Optionally, combined Fig. 9 As shown, the second water storage area 300 also includes a guide side 320. In the left-right direction, the guide side 320 is located on the side of the guide bottom surface 310 adjacent to the drainage area 400. The angle β of the guide side 320 relative to the front-back direction is in the range of 5-10 degrees.

[0121] Specifically, the diversion side surface 320 plays a role in guiding the flow direction of water. For example, when manual drainage is required, the air conditioner is tilted to the right by human power, and the water flows along the diversion side surface 320 to the main water collection area 100 and the drainage area 400. The angle β between the diversion side surface 320 and the front-to-back direction is in the range of 5 to 10 degrees. Under this angle range, the water can smoothly flow to the main water collection area 100 and the drainage area 400 by gravity; at the same time, the diversion side surface 320 gradually approaches the back of the chassis from front to back, which means that the diversion side surface 320 is equivalent to a plane perpendicular to the horizontal plane and extending in the front-to-back direction, which is formed by rotating clockwise at an angle of β.

[0122] At the same time, the second water storage area 300 is also provided with a wind shield 330, which is located at the water outlet of the second water storage area 300. The wind shield 330 mainly serves to prevent the wind from the main water collection area 100 from blowing into the second water storage area 300.

[0123] The air conditioner chassis structure of the present invention provides a flow guide side surface in the second water storage area, so that condensed water flows out of the second water storage area more smoothly.

[0124] The present embodiment provides an air conditioner chassis for installing an evaporator 10, and a water storage area 200 is provided on the chassis. The water storage area 200 is located on one side of the evaporator 10 in the assembled state, and a water passing notch 221 and a wind shield structure 210 are provided on the side of the water storage area 200 close to the evaporator 10. The wind shield structure 210 is suitable for blocking air from the direction of the evaporator 10 from entering the water storage area 200 through the water passing notch 221 in the assembled state.

[0125] The chassis is provided with a main water collection area 100 and a water storage area 200, which are connected at a water gap 221, and a wind shielding structure 210 is arranged in the water storage area 200 near the water gap 221. When the evaporator 10 is assembled on the chassis, the main water collection area 100 is located below the evaporator 10, the water storage area 200 is located on the left side of the evaporator 10, and the wind shielding structure 210 abuts against the bracket 11 on the left side of the evaporator 10, so that the wind shielding structure 210 can provide support for the evaporator 10. When the air conditioner is working, the evaporator 10 will produce a large amount of condensed water, most of which will drip into the main water collection area 100 along the evaporator 10, and a small part will drip into the water storage area 200 along the bracket 11 on the left side of the evaporator 10. This small part of condensed water is collected in the water storage area 200, and flows into the main water collection area 100 from the water gap 221, and then gathers in the water trough on the chassis, and is hit by the water motor installed in the water trough to be atomized and hit the hot condenser, thereby evaporating the condensed water. In the prior art, the air blown into the evaporator 10 circulates inside the evaporator 10 to perform heat exchange, and the air circulating inside the evaporator 10 also flows in the main water collection area 100. However, since the main water collection area 100 is connected to the water storage area 200 at the water gap 221, the air flowing in the main water collection area 100 will flow into the water storage area 200 from the water gap 221. In the absence of a wind shielding structure 210, the air in the evaporator 10 enters the water storage area 200 from the water gap 221 without any hindrance, resulting in air leakage in the evaporator 10 area, affecting the heat exchange efficiency of the evaporator 10. In this embodiment, a wind shielding structure 210 is provided in the water storage area 200, so that the air flowing from the main water collection area 100 to the water gap 221 cannot flow smoothly into the water storage area 200 due to the hindrance of the wind shielding structure 210, and most of it will flow back into the main water collection area 100.

[0126] In this way, the setting of the wind shield structure 210, on the one hand, strengthens the structural strength of the water storage area 200, and can provide support for the evaporator 10 in the assembled state; on the other hand, it can also prevent the air in the evaporator 10 from entering the water storage area 200 through the water passing gap 221, thereby playing a role in preventing air leakage and improving the working efficiency of the evaporator 10.

[0127] Optional, combined Fig.10 and Fig.11 As shown, the wind shielding structure 210 includes a first wind shielding rib 211 and a second wind shielding rib 212 , and the projections of the first wind shielding rib 211 and the second wind shielding rib 212 on the plane where the water passing notch 221 is located cover the water passing notch 221 .

[0128] The windshield structure 210 includes two windshields, namely, a first windshield rib 211 and a second windshield rib 212, and the heights of the first windshield rib 211 and the second windshield rib 212 are higher than the height of the water-passing gap 221. The first windshield rib 211 and the second windshield rib 212 can be connected to each other at the end, that is, the rear end of the first windshield rib 211 is connected to the front end of the second windshield rib 212; they can also be staggered at the end, that is, when the first windshield rib 211 and the second windshield rib 212 are connected to each other, the rear end of the first windshield rib 211 and the front end of the second windshield rib 212 overlap, and when the first windshield rib 211 and the second windshield rib 212 are not connected, the rear end of the first windshield rib 211 and the front end of the second windshield rib 212 are staggered in the front-to-back direction. That is to say, the projection of the first wind shield rib 211 on the plane where the water gap 221 is located is the first projection, and the projection of the second wind shield rib 212 on the plane where the water gap 221 is located is the second projection. The first projection and the second projection may intersect or be connected at the edge of the projection. The projection of the first wind shield rib 211 and the second wind shield rib 212 on the plane where the water gap 221 is located is the sum of the areas of the first projection and the second projection, and the sum of the areas of the first projection and the second projection is greater than the area of ​​the water gap 221, and the water gap 221 can be completely covered. It should be noted that when the first projection and the second projection intersect, the area of ​​the first projection is added to the area of ​​the second projection, and then the area of ​​the intersection of the first projection and the second projection is subtracted. The final projection area is the sum of the areas of the first projection and the second projection.

[0129] In this way, when the air in the evaporator 10 is blown into the water storage area 200 through the water passing gap 221, all of it can be blown onto the wind shield structure 210, and most of it can flow back into the main water collection area 100 under the obstruction of the first wind shield rib plate 211 and the second wind shield rib plate 212, thereby reducing air leakage of the evaporator 10.

[0130] Optional, combined Fig.11 As shown, the wind shield structure 210 also includes a third wind shield rib 213, the first wind shield rib 211 and the second wind shield rib 212 are both connected to the third wind shield rib 213, and are respectively located on both sides of the third wind shield rib 213; one end of the third wind shield rib 213 extends to the water passing gap 221, and divides the water passing gap 221 into two parts.

[0131] The third wind shield rib 213 is arranged in the water storage area 200 along the left-right direction, and the right end of the third wind shield rib 213 is located at the water-passing gap 221, dividing the water-passing gap 221 into two gaps, namely the first gap 2211 and the second gap 2212. The first wind shield rib 211 and the second wind shield rib 212 are respectively located at the front and rear sides of the third wind shield rib 213. The front end of the first wind shield rib 211 is a free end and does not form a connection relationship with other components, and the rear end of the first wind shield rib 211 is connected to the third wind shield rib 213; the front end of the second wind shield rib 212 is connected to the third wind shield rib 213, and the rear end of the second wind shield rib 212 is a free end and does not form a connection relationship with other components.

[0132] In this way, the third wind shield rib 213 divides the water gap 221 into two, so that the airflow flowing into the water storage area 200 from the water gap 221 is diverted at the water gap 221, reducing the flow rate of the airflow. According to Bernoulli's principle, when the flow rate of the airflow decreases, the pressure will increase, and the resistance of the airflow when flowing toward the water storage area 200 will be greater, further reducing the air leakage of the evaporator 10.

[0133] Optionally, the first wind shielding ribs 211, the second wind shielding ribs 212 and the third wind shielding ribs 213 are distributed in a herringbone pattern.

[0134] That is to say, the wind shielding structure 210 is a fishbone structure, wherein the third wind shielding rib plate 213 constitutes a main structure of the fishbone, and the first wind shielding rib plate 211 and the second wind shielding rib plate 212 constitute the side branch structures on both sides of the main structure of the fishbone.

[0135] The fishbone structure of the windshield structure 210 can ensure that the water storage area 200 is not prone to shrinkage during the injection molding of the chassis, thereby improving the manufacturing quality of the chassis.

[0136] Optionally, the areas of the first notch 2211 and the second notch 2212 are equal.

[0137] That is to say, the end of the third wind shielding rib 213 is located in the middle of the water passing gap 221, dividing the water passing gap 221 into two equal parts.

[0138] In this way, after the airflow flowing into the water storage area 200 through the water passing gap 221 is split at the water passing gap 221, the pressures at the first gap 2211 and the second gap 2212 are the same, and the obstruction effects on the airflow are also equivalent, thereby avoiding the situation where one of the two gaps obstructs the airflow much less than the other gap, causing most of the airflow blowing toward the water passing gap 221 to flow into the water storage area 200 from the gap with less obstruction, thereby further reducing air leakage of the evaporator 10.

[0139] Optional, combined Figures 10 to 17As shown, the water storage area 200 has a first side wall 220 in its length direction, and the first side wall 220 is a V-shaped structure. The opening of the V-shaped structure faces the side of the water storage area 200 away from the evaporator 10, and the water passing notch 221 is arranged at the top of the V-shaped structure, which is suitable for guiding the condensed water to flow along the first side wall 220 to the water passing notch 221.

[0140] The dimension of the water storage area 200 in the front-to-back direction is greater than its dimension in other directions, so the length direction of the water storage area 200 is the front-to-back direction, the first side wall 220 is arranged on the water storage area 200 along the front-to-back direction, and the water-passing notch 221 is provided on the first side wall 220. The first side wall 220 is in a V-shaped structure, and the water-passing notch 221 is provided at the top of the V-shaped structure. Since the evaporator 10 and the main water collection area 100 are located on the right side of the water storage area 200, the opening of the V-shaped structure of the first side wall 220 faces leftward and the top faces rightward.

[0141] In this way, the condensed water dripping into the water storage area 200 can flow along the first side wall 220 to the water passing gap 221, so that the first side wall 220 has a diversion effect, preventing the condensed water from being retained in the water storage area 200, thereby improving the drainage effect of the chassis.

[0142] Optional, combined Figures 10 to 17 As shown, the water storage area 200 has a second side wall 230 in its length direction, and a reinforcement structure 231 is provided on the second side wall 230 .

[0143] That is to say, the second side wall 230 is arranged on the water storage area 200 along the front-to-back direction. The water storage area 200 as a whole is similar to a rectangular groove structure, and has side walls in the front, rear, left and right directions, and the first side wall 220 and the second side wall 230 respectively constitute the two side walls of the water storage area 200 in the left and right directions, that is, the first side wall 220 and the second side wall 230 are also the left side wall and the right side wall of the water storage area 200 respectively. The reinforcement structure 231 is arranged on the second side wall 230 of the water storage area 200. In this embodiment, the water storage area 200 is arranged at the left end of the chassis, and the left side wall of the water storage area 200 is a part of the left side wall of the chassis, so the reinforcement structure 231 is also equivalent to being arranged on the left side wall of the chassis.

[0144] In this way, the structural strength of the second side wall 230 on the water storage area 200 can be enhanced, thereby improving the strength of the chassis, so that the water storage area 200 of the chassis is not easily deformed when subjected to vibration, shock or impact during transportation or when the air conditioner is in operation, thereby improving the use quality of the chassis.

[0145] Optionally, the reinforcement structure 231 may be a plate-like structure, a block-like structure, a strip-like structure or other structures, which are not limited in detail in this embodiment.

[0146] Optionally, a plurality of reinforcing structures 231 are provided and are evenly spaced and distributed on the second side wall 230 .

[0147] The plurality of reinforcement structures 231 are distributed on the second side wall 230 along the length direction of the second side wall 230 , and the distance between two adjacent reinforcement structures 231 is equal.

[0148] In this way, by further enhancing the structural strength of the second side wall 230, the strength and quality of the left side wall of the chassis are improved, thereby extending the service life of the chassis.

[0149] Optional, combined Figures 10 to 17 As shown, the V-shaped structure of the first side wall 220 has a first side edge 222 and a second side edge 223 at the front and rear ends of the water passing notch 221, respectively. The inclination angle α1 of the first side edge 222 relative to the front-to-back direction is between 5°-10°, and / or the inclination angle α2 of the second side edge 223 relative to the front-to-back direction is between 5°-10°.

[0150] The first side wall 220 is divided into two sections by the water-passing notch 221, and the first side wall 220 is arranged perpendicular to the left and right directions. Fig.14 There are two line segments in the middle, and these two line segments respectively constitute the two sides of the V-shape, wherein the line segment at the front end of the water-passing notch 221 constitutes the first side 222 of the V-shape, and the line segment at the rear end of the water-passing notch 221 constitutes the second side 223 of the V-shape. The inclination angle α1 of the first side 222 relative to the front-to-back direction is the angle between the first side 222 and the front-to-back direction, and the inclination angle α2 of the second side 223 relative to the front-to-back direction is the angle between the second side 223 and the front-to-back direction. When the inclination angle of the first side 222 and / or the second side 223 relative to the front-to-back direction is too large, it means that the inclination angle of the first side wall 220 divided into two sections by the water-passing notch 221 is also large. Due to the structural limitation of the chassis itself, when the inclination angle of the first side wall 220 is too large, it will affect other structures on the chassis, or reduce the area of ​​the water storage area 200, reduce the water storage capacity of the water storage area 200, and cause the condensed water to overflow the chassis when the generated condensed water increases, causing the air conditioner to leak.

[0151] In this embodiment, α1 and / or α2 are set between 5°-10°. Within this angle range, the comprehensive performance of the water storage capacity and diversion effect of the water storage area 200 is better, which can ensure that the water storage area 200 not only has sufficient water storage area to prevent water leakage of the air conditioner without affecting other structures of the chassis, but also ensures that the first side wall 220 has a diversion effect and a good drainage effect.

[0152] Optional, combined Fig.15 and Fig.16As shown, the first wind shielding rib 211 and the second wind shielding rib 212 are arranged obliquely, and the free ends of the first wind shielding rib 211 and the second wind shielding rib 212 are close to the first side wall 220 , which are suitable for guiding the condensed water to flow toward the first side wall 220 .

[0153] That is to say, the free ends of the first wind shield rib 211 and the second wind shield rib 212 are respectively inclined toward the first side wall 220 located at the front end and the rear end of the water-passing notch 221, that is, the first side wall 220 divided into two sections by the water-passing notch 221 is extended to intersect with the third wind shield rib 213, and then from the front to the rear, the minimum distance between the first wind shield rib 211 and the first side wall 220 after extension and located at the front end of the third wind shield rib 213 gradually increases; the minimum distance between the second wind shield rib 212 and the first side wall 220 after extension and located at the rear end of the third wind shield rib 213 gradually decreases. In conjunction with the coordinate system in the figure, the first wind shield rib 211 is inclined toward the right rear, and the second wind shield rib 212 is inclined toward the right front.

[0154] In this way, it is possible to prevent condensed water from being blocked by the first wind shield rib 211 and the second wind shield rib 212 on the side away from the water passing notch 221, so that the condensed water dripping into the water storage area 200 flows along the first wind shield rib 211 and the second wind shield rib 212 to the first side wall 220, and then flows along the first side wall 220 to the water passing notch 221, thereby improving the diversion effect and enhancing the drainage effect of the water storage area 200.

[0155] Optional, combined Fig.16 As shown, the inclination angle α3 of the first wind shielding rib 211 relative to the front-rear direction is between 15° and 30°, and / or the inclination angle α4 of the second wind shielding rib 212 relative to the front-rear direction is between 15° and 30°.

[0156] Since the first wind shield rib 211 and / or the second wind shield rib 212 are plate-like structures with uniform thickness, the inclination angle α3 of the first wind shield rib 211 relative to the front-to-back direction is the angle between the side of the first wind shield rib 211 located in the left-right direction and the front-to-back direction; the inclination angle α4 of the second wind shield rib 212 relative to the front-to-back direction is the angle between the side of the second wind shield rib 212 located in the left-right direction and the front-to-back direction. The first wind shield rib 211 and / or the second wind shield rib 212 are arranged perpendicular to the horizontal plane, wherein the horizontal plane also refers to a plane perpendicular to the up-down direction. Fig.16As shown, in this embodiment, the angle between the left side surface of the first wind shielding rib 211 and / or the second wind shielding rib 212 and the front-to-back direction is used as an example for explanation. The left side surface of the first wind shielding rib 211 and / or the second wind shielding rib 212 is shown as a line segment in the figure. A water passing area is formed between the free ends of the first wind shielding rib 211 and the second wind shielding rib 212 and the first side wall 220. The inclination angle of the first wind shielding rib 211 relative to the front-to-back direction is used as an example for explanation. When the inclination angle of the first wind shield rib 211 relative to the front-to-back direction is set too large, the minimum distance between the free end of the first wind shield rib 211 and the first side wall 220 becomes smaller, so that the water flow area formed between the free end of the first wind shield rib 211 and the first side wall 220 becomes smaller, thereby extending the drainage time of the water storage area 200 and reducing the drainage effect of the water storage area 200; when the inclination angle of the first wind shield rib 211 relative to the front-to-back direction is set too small, the first wind shield rib 211 almost loses its water guiding function and the diversion effect is poor.

[0157] In this embodiment, α3 and / or α4 are set between 15° and 30°. Within this angle range, it is ensured that the first wind shielding rib plate 211 and / or the second wind shielding rib plate 212 have a certain flow guiding effect, and it is ensured that the condensed water can smoothly flow from the water passing area formed between the free end of the first wind shielding rib plate 211 and / or the second wind shielding rib plate 212 and the first side wall 220 to the water passing gap 221, and the drainage effect is better.

[0158] Optional, combined Fig.14 and Fig.17 As shown, one end of the third wind shield rib 213 extends to the water passing notch 221, and the other end of the third wind shield rib 213 extends to the side of the water storage area 200 away from the evaporator 10, and divides the water storage area 200 into a first water storage tank 240 and a second water storage tank 250. The bottom surface of the first water storage tank 240 and the bottom surface of the second water storage tank 250 are on a side away from the third wind shield rib 213 that is higher than the side connected to the third wind shield rib 213, and are suitable for guiding condensed water to flow toward the third wind shield rib 213.

[0159] The third wind shield rib 213 is arranged in the left-right direction in the water storage area 200. Since the second side wall 230 is the side of the water storage area 200 away from the evaporator 10, the third wind shield rib 213 extends from the water passing notch 221 to the second side wall 230, dividing the water storage area 200 into two water storage tanks, namely the first water storage tank 240 and the second water storage tank 250. The first water storage tank 240 is located at the front end of the third wind shield rib 213, and the second water storage tank 250 is located at the rear end of the third wind shield rib 213. The side of the bottom surface of the first water storage tank 240 away from the third wind shielding rib 213 is higher than the side connected to the third wind shielding rib 213, and the side of the bottom surface of the second water storage tank 250 away from the third wind shielding rib 213 is higher than the side connected to the third wind shielding rib 213. That is to say, the entire bottom surface of the water storage area 200 sinks at the third wind shielding rib 213, so that the cross-section of the bottom surface of the water storage area 200 is V-shaped, and the top of the V-shape is the lowest point when water flows. Taking the bottom surface of the first water storage tank 240 as an example, combined with the coordinate system in the figure, the front end of the bottom surface of the first water storage tank 240 is higher than the rear end. The condensed water dripping onto the first water storage tank 240 and the second water storage tank 250 flows toward the third wind shielding rib 213 under the guiding effect of the bottom surface of the first water storage tank 240 and the bottom surface of the second water storage tank 250, and then flows along the third wind shielding rib 213 to the water gap 221 and is discharged from the water storage area 200.

[0160] In this way, the speed at which the condensed water flows in the first water tank 240 and the second water tank 250 toward the third wind shield rib 213 is increased, so that the condensed water can be discharged from the water storage area 200 faster and the condensed water is discharged more cleanly, preventing the condensed water from being retained in the first water tank 240 and the second water tank 250 to form accumulated water, thereby further improving the drainage efficiency and drainage effect of the water storage area 200.

[0161] Optional, combined Fig.17 As shown, the angle α5 between the bottom surface of the first water storage tank 240 and the horizontal plane is between 2°-5°, and / or the angle α6 between the bottom surface of the second water storage tank 250 and the horizontal plane is between 2°-5°.

[0162] The angle α5 between the bottom surface of the first water storage tank 240 and the horizontal plane and the angle α6 between the bottom surface of the second water storage tank 250 and the horizontal plane respectively reflect the degree of inclination of the bottom surface of the first water storage tank 240 and the bottom surface of the second water storage tank 250 toward the third wind shielding rib 213. Taking the angle α5 between the bottom surface of the first water storage tank 240 and the horizontal plane as an example, when α5 is set too large, the bottom surface of the water storage area 200 sinks deeper at the third wind shielding rib 213, making the distance between the bottom surface of the chassis located at the water storage area 200 and the ground smaller, and when the air conditioner is moved, the chassis is easy to scratch or interfere with obstacles on the bottom surface, affecting the movement and transportation of the air conditioner; when α5 is set too small, the bottom surface of the first water storage tank 240 and the bottom surface of the second water storage tank 250 are almost parallel to the ground, and the condensed water flows slowly in the water storage area 200, and the diversion effect is poor.

[0163] In this embodiment, α5 and / or α6 are set between 2°-5°. Thus, within this angle range, not only can the bottom surface of the first water storage tank 240 and the bottom surface of the second water storage tank 250 have a good diversion effect, but also it can ensure that there is a sufficient height between the bottom surface of the water storage area 200 and the ground, so that the air conditioner can be moved and transported smoothly.

[0164] Optional, combined Figures 18 to 20 As shown, the bottom surface of the first water storage tank 240 and the bottom surface of the second water storage tank 250 are higher than the side where the water passing notch 221 is located, which is suitable for guiding condensed water to flow toward the water passing notch 221.

[0165] That is to say, after the entire bottom surface of the water storage area 200 sinks at the third wind shield rib 213, it sinks again at the side where the water passing notch 221 is located, or the entire bottom surface of the water storage area 200 does not sink at the third wind shield rib 213, but only sinks at the side where the water passing notch 221 is located. Taking the bottom surface of the first water storage tank 240 as an example, combined with the coordinate system in the figure, on the basis of setting the front end of the bottom surface of the first water storage tank 240 higher than the rear end, the left side of the bottom surface of the first water storage tank 240 is set higher than the right side, or the front end and the rear end of the bottom surface of the first water storage tank 240 are at the same height, and the left side of the bottom surface of the first water storage tank 240 is higher than the right side. The condensed water dripping onto the first water tank 240 and the second water tank 250 flows toward the third wind shielding rib 213 under the guidance of the bottom surface of the first water tank 240 and the bottom surface of the second water tank 250 respectively, and then flows along the third wind shielding rib 213 to the water passing gap 221 and is discharged from the water storage area 200.

[0166] In this way, the flow rate of the condensed water in the first water tank 240 and the second water tank 250 is increased, so that the condensed water can be discharged from the water storage area 200 faster and the condensed water is also discharged more cleanly, preventing the condensed water from being retained in the first water tank 240 and the second water tank 250 to form stagnant water and corrode the chassis. This not only further improves the drainage efficiency and drainage effect of the water storage area 200, but also improves the quality of the chassis and extends the service life of the chassis.

[0167] Optional, combined Figures 18 to 20 As shown, the intersection line formed by the intersection of the bottom surface of the first water tank 240 and the plane perpendicular to the front-to-back direction has an inclination angle of 2°-5° relative to the left-to-right direction, and / or the intersection line formed by the intersection of the bottom surface of the second water tank 250 and the plane perpendicular to the front-to-back direction has an inclination angle of 2°-5° relative to the left-to-right direction.

[0168] Taking the bottom surface of the first water storage tank 240 as an example, the intersection line formed by the intersection of the bottom surface of the first water storage tank 240 and the plane perpendicular to the front-rear direction is shown in Fig. 20 There is a diagonal line segment in the middle. Fig. 20 The dotted line in the figure refers to the left and right directions, which are also the projections of the horizontal plane perpendicular to the front-back direction. The intersection formed by the intersection of the bottom surface of the first water storage tank 240 and the plane perpendicular to the front-back direction has an inclination angle relative to the left and right directions, which is the angle α7 formed between the oblique line segment and the dotted line. When α7 is set too large, the bottom surface of the water storage area 200 sinks deeper on the side where the water-passing notch 221 is located, making the distance between the bottom surface of the chassis located at the water storage area 200 and the ground smaller. When the air conditioner is moved, the chassis is prone to scratching or interfering with obstacles on the bottom surface, affecting the movement and transportation of the air conditioner; when α7 is set too small, the bottom surface of the first water storage tank 240 and the bottom surface of the second water storage tank 250 are almost parallel to the ground, and the condensed water flows slowly in the water storage area 200, resulting in poor diversion effect.

[0169] In the present embodiment, the inclination angle of the intersection line formed by the intersection of the bottom surface of the first water storage tank 240 and the plane perpendicular to the front-to-back direction relative to the left-to-right direction, and / or the inclination angle of the intersection line formed by the intersection of the bottom surface of the second water storage tank 250 and the plane perpendicular to the front-to-back direction relative to the left-to-right direction is set to be between 2°-5°. In this way, within this angle range, not only can it be ensured that the bottom surface of the first water storage tank 240 and the bottom surface of the second water storage tank 250 have a good diversion effect, but it can also ensure that there is a sufficient height between the bottom surface of the water storage area 200 and the ground, so that the air conditioner can be smoothly moved and transported.

[0170] This embodiment provides an air conditioner, comprising any of the above-mentioned air conditioner chassis structures.

[0171] In this embodiment, the air conditioner chassis structure also includes: a water pumping mechanism 800, a water pumping motor area 600 and a condenser. The water pumping mechanism 800 is suitable for pumping water in the water pumping tank 700 onto the condenser, and the water pumping motor area 600 is suitable for collecting water on the water pumping mechanism 800.

[0172] It should be noted that a water level switch is provided in the area where the water level switch area 500 is located, which is used to monitor the highest water level in the chassis, and the water level switch is suspended above the water level switch area through a bracket. The water level switch floats up and down with the water level. The water level in the chassis is monitored by the water level switch to avoid excessive water accumulation in the chassis and affect the working performance of the air conditioner. Generally, when there is less condensed water, the water is first collected in the water tank 700, and the water in the water tank 700 is pumped onto the air conditioner heat exchanger through the water wheel 810 to improve the heat exchange efficiency of the heat exchanger. In this process, it is equivalent to pumping out the water in the water tank 700. In order to ensure that there is always water in the water tank 700, at this time, the water level switch area 500 is connected to the water tank 700 so that the water in the water level switch area 500 can be gathered in the water tank 700, instead of directly connecting the water level switch area 500 to the drainage area 400. When the When the water in the water level switch area 500 overflows to a certain extent, the water in the water level switch area 500 is discharged. The water discharged from the water level switch area 500 is first gathered in the water pumping trough 700 to ensure the operation of the water pumping mechanism 800. During this process, since the water pumping motor shaft 820 is connected to the water pumping wheel 810, part of the water on the water pumping wheel 810 will flow to the water pumping motor shaft 820 and be thrown out as the water pumping motor shaft 820 rotates. The water thrown out by the water pumping motor shaft 820 is directly gathered in the drainage area 400 and discharged through the drainage area.

[0173] The advantage of such an arrangement is that, by connecting the water level switch area 500 with the water pumping trough 700, when the water in the water level switch area 500 is discharged, it is not directly discharged from the air conditioner chassis, but the water in the water level switch area 500 is discharged to the water pumping trough 700, thereby ensuring the operation of the water pumping mechanism 800 and allowing the water in the water pumping trough 700 to be pumped out through the water pumping mechanism; in addition, the drainage area 400 collects the water thrown out from the water pumping motor shaft 820 of the water pumping mechanism 800.

[0174] In this embodiment, the water pumping motor area 600 is only connected to the drainage area 400. The water pumping motor area 600 is located below the water pumping motor shaft 820 and is suitable for directing the water on the water pumping motor shaft 820 to the drainage area 400. Since the water pumping motor will throw water to a certain distance when it rotates, the water pumping motor area 600 is set to gather the water on the water pumping motor shaft 820 and make it flow into the drainage area 400. In addition, the water pumping motor area 600 is only connected to the drainage area 400. Figure 1 As shown, the water pumping trough 700 is located between the main water collection area 100 and the water pumping motor area 600. The main water collection area 100 and the water pumping motor area 600 are separated by the water pumping trough 700 to prevent water on the water pumping mechanism from entering the main water collection area 100 again, to prevent repeated circulation of condensed water, and to cause incomplete drainage. Instead, the water is directly discharged from the air conditioner through the drainage area.

[0175] In this embodiment, the air conditioner chassis structure also includes a water pumping motor area 600, which is only connected to the drainage area 400 and is suitable for guiding the water on the water pumping motor shaft 820 to the drainage area 400. Since the water pumping motor will throw water to a certain distance when it rotates, the water pumping motor area 600 is set to gather the water on the water pumping motor shaft 820 and make it flow into the drainage area 400. In addition, the water pumping motor area 600 is only connected to the drainage area 400. Figure 1 As shown, the water pumping trough 700 is located between the main water collection area 100 and the water pumping motor area 600. The main water collection area 100 and the water pumping motor area 600 are separated by the water pumping trough 700 to prevent water on the water pumping mechanism from entering the main water collection area 100 again, to prevent repeated circulation of condensed water, and to cause incomplete drainage. Instead, the water is directly discharged from the air conditioner through the drainage area.

[0176] In this embodiment, if Fig.21 and Fig. 22 As shown, the pumping motor area 600 may include a water-guiding bottom surface 620. In some examples, when the air conditioner chassis structure is placed horizontally, in the left-right direction, the height of the water-guiding bottom surface 620 on the side away from the drainage area 400 may be higher than the height of the water-guiding bottom surface 620 on the side close to the drainage area 400. In this case, the height difference between the left and right sides of the water-guiding bottom surface may cause the pumping motor area to be in an inclined state, so that the condensed water inside the pumping motor area flows to the lower side, that is, flows in the direction of the drainage area, thereby facilitating the discharge of water in the pumping motor area, improving its discharge efficiency, and at the same time ensuring the thoroughness of the discharge of the condensed water inside the pumping motor area.

[0177] In this embodiment, if Fig. 22As shown, the angle between the water-guiding bottom surface 620 and the horizontal plane can be ξ, and the numerical value of ξ is not particularly limited. In some examples, the value range of ξ can be 2°≤ξ≤10°. In other examples, the value of ξ can also be 2°≤ξ≤5°. Here, the so-called angle between the water-guiding bottom surface 620 and the horizontal plane is ξ, which means that when the air conditioner chassis structure is placed horizontally, the angle between the water-guiding bottom surface 620 and the horizontal plane is ξ. Under normal circumstances, when the angle is too large, that is, the inclination angle is too large, the water flow rate will be too large, and it is easy to splash during the outflow of condensed water, so as to affect the overall performance of the base and its air conditioner; and when the angle is too small, that is, the inclination angle is too small, the water flow rate is too small, thereby affecting the discharge efficiency of condensed water. Therefore, by setting the angle between the water-guiding bottom surface and the horizontal plane within a certain range, the discharge efficiency of condensed water can be guaranteed, and the condensed water will not splash, etc., thereby improving the smoothness and stability of condensed water discharge.

[0178] In this embodiment, if Fig.21 and Fig. 22 As shown, the water pumping motor area 600 may be provided with a water pumping area reinforcement rib 630. In this case, by providing the water pumping area reinforcement rib, the mechanical properties of the water pumping motor area can be improved, thereby improving the air conditioner chassis structure and the stability of the air conditioner, extending its service life, etc.; and the provision of the water pumping area reinforcement rib also has a certain wind blocking effect, thereby effectively preventing the occurrence of air leakage of the air conditioner, etc., and improving the comfort of the air conditioner.

[0179] In this embodiment, there is no particular limitation on the number of the water-splashing area reinforcement ribs 630. In some examples, the number of the water-splashing area reinforcement ribs 630 may be more than one, such as two, three, or four. Thus, different numbers of drainage area reinforcement ribs may be provided according to the number of water-conducting areas, thereby improving the overall stability of the air conditioner chassis structure.

[0180] In this embodiment, there is no particular restriction on the direction in which the water-splashing area reinforcement ribs 630 are arranged. In some examples, the water-splashing area reinforcement ribs 630 may be arranged along the front-to-back direction. Here, the so-called front-to-back direction refers to the front-to-back direction when the air conditioner chassis structure is placed horizontally, i.e., the front-to-back direction of the air conditioner chassis structure. Figure 1The coordinate direction in the water pumping area. It should be noted that the water pumping area reinforcement ribs are arranged on the water-guiding bottom surface 620 and are connected to the side panels of the water pumping motor area, thereby improving the mechanical properties of the water-guiding bottom surface and further enhancing the overall stability of the water pumping motor area. In addition, in the present embodiment, the purpose of the water pumping area reinforcement ribs 630 being arranged along the front-to-back direction is to make the water pumping area reinforcement ribs 630 face the side wall of the water pumping motor area that is connected to the drainage area 400. The water pumping area reinforcement ribs 630 can be directly arranged in the direction of the drainage area 400. Here, the so-called arrangement in the direction of the drainage area means that the water pumping area reinforcement ribs 630 are inclined in the direction of the drainage area. In this case, the condensed water in the water pumping motor area can be further guided to flow in the direction of the drainage area, thereby improving the drainage efficiency and thoroughness of the air conditioner chassis structure.

[0181] In this embodiment, if Figure 1 and Figure 2 As shown, the pumping motor area 600 can be connected to the drainage area 400 through a connecting channel 610, which is suitable for introducing water from the pumping motor area 600 into the drainage area 400. One end of the connecting channel 610 is connected to the pumping motor area 600, and the other end is connected to the water guide area 411 of the drainage area 400. The pumping motor area 600 is located at the rear side of the drainage area 400, and the motor shaft is arranged along the front-to-back direction. The water in the pumping motor area 600 flows from left to right, and the water in the drainage area 400 flows from back to front. The drainage area 400 is connected to the front side wall of the pumping motor area 600, and the drainage area 400 is located in the right front of the pumping motor area 600. In this embodiment, by setting a connecting channel between the pumping motor area and the drainage area, the condensed water in the pumping motor area can be discharged more conveniently, the drainage efficiency of the base can be improved, and the condensed water can be effectively prevented from accumulating in the pumping motor area and overflowing from the base, and the thoroughness of the drainage of the base can be improved, thereby improving the performance of the air conditioner using the chassis.

[0182] In this embodiment, as shown in Figure 23, the connecting channel 610 also includes a transition side wall 613, which is suitable for the width of the inlet of the connecting channel 610 and the outlet of the connecting channel 610 along the direction of water flow. There is no special restriction on the size. The width here refers to the distance between the two transition side walls 613 of the connecting channel 610. In some examples, the width of the inlet of the connecting channel 610 can be greater than the width of the outlet of the connecting channel 610. In some examples, the transition side wall 613 is suitable for gradually reducing the width of the connecting channel 610 along the direction of water flow. In this case, the condensed water in the water pumping motor area can be effectively converged, and a convergence force can be formed inside the condensed water to accelerate its flow into the drainage area, thereby improving the drainage efficiency of the air conditioner chassis structure.

[0183] In this embodiment, if Fig.23As shown, the transition side wall 613 includes multiple transition surfaces, where the transition surfaces can be two or more. In this embodiment, the transition side wall 613 includes a first transition surface 6131, a second transition surface 6132 and a third transition surface 6133. Along the water flow direction, the first transition surface 6131, the second transition surface 6132 and the third transition surface 6133 are connected in sequence. Here, the first transition surface 6131 and the second transition surface 6132 are set as arc surfaces, and the third transition surface 6133 is set as an inclined surface. In general, water converges through the connecting channel and flows into the drainage area, and the water flow direction changes at the connecting channel. Therefore, the transition side wall of the connecting channel is set as a transition arc surface. The setting of multiple transition surfaces can make the condensed water gradually turn, playing the role of multiple slow flow.

[0184] In this embodiment, the height of the water pumping motor area 600 can be greater than the height of the drainage area 400. Here, the so-called height refers to the height difference between the water pumping motor area 600 or the drainage area 400 and the placement plane when the air conditioner chassis structure is placed horizontally. In this case, making the water pumping motor area higher than the drainage area can further improve the drainage efficiency of the air conditioner chassis structure, and facilitate the complete drainage of condensed water in the water pumping motor area, thereby improving the performance of the air conditioner.

[0185] like Figure 21 to Figure 23 As shown, the drainage area 400 includes a water guide area 411, a transition area 412 and a drainage pipe 420. The drainage pipe 420 is connected to the transition area 412. The water guide area 411 and the transition area 412 can be connected. The water guide area 411 is suitable for introducing water into the transition area 412. In this embodiment, by arranging a drainage pipe on the chassis structure, when the chassis structure is applied to the air conditioner, it is more conducive to collecting and discharging condensed water generated during the operation of the air conditioner. In addition, by arranging a transition area connected to the drainage pipe in the drainage area, the condensed water drawn from the water guide area can first flow through the transition area and then be discharged from the transition area through the drainage pipe. Therefore, the flow path of the condensed water can be optimized, the drainage efficiency can be improved, the drainage can be smoother, and the drainage can be more thorough.

[0186] In this embodiment, the shape structure of the transition zone 412 is not particularly limited. In some examples, the transition zone 412 can be a transition camber. In other examples, the transition zone 412 can also be an arc transition zone. In this case, the connection between the transition zone and the drain pipe can be more conveniently achieved, and the smoothness of the connection between the transition zone and the drain pipe can be improved to further improve the smoothness of drainage, which is more conducive to improving drainage efficiency, ensuring the thoroughness of drainage, and preventing water from remaining in the chassis structure and affecting the overall performance of the air conditioner.

[0187] In this embodiment, if Fig.25As shown, the arc angle of the cross section of the transition arc surface can be η 1 , η 1 There is no particular limit on the value of . 1 The value range of can be π / 4≤η 1 ≤π / 2. In other examples, η 1 The value of can also be 2π / 5, that is, the cross section of the transition arc surface can also be one-fifth of a circle. In this case, the connection between the transition area and the drain pipe can be made more effective, and obstacles such as grooves or convex edges in the drainage path can be reduced to make the drainage path smoother, further improve the smoothness of drainage, and be more conducive to improving drainage efficiency, ensuring the thoroughness of drainage, and preventing water from remaining in the chassis structure and affecting the overall performance of the air conditioner.

[0188] In addition, in this embodiment, there is no particular limitation on the manufacturing method of the transition zone 412. In some examples, the transition zone 412 can be formed by mold injection molding. In other examples, the transition zone 412 can be formed integrally with the drain pipe 420 and the water guide area 411 by mold injection molding. In this case, through mold injection molding or integral molding, it is not easy to form flash or burrs and other debris that may block the drain pipe in the transition zone, thereby further improving the efficiency of condensed water discharge and further ensuring the thoroughness of condensed water discharge.

[0189] In this embodiment, if Fig.26 As shown, the bottom surface of the water guide area 411 is a water guide slope 4113. When the chassis structure is placed horizontally, the height of the water guide slope 4113 away from the transition area 412 is higher than the height of the side where the water guide slope 4113 is connected to the transition area 412. In other examples, the water guide area 411 may also include a first side plate. In this case, by tilting the water guide slope and making the water inflow side higher than the water outflow side, that is, tilting the water outflow path, the discharge efficiency of the condensed water can be further improved, and the thoroughness of the condensed water discharge can be further ensured.

[0190] In this embodiment, the angle between the water guide slope 4113 and the horizontal plane can be η 2 , η 2 There is no particular limit on the value of . 2 The value range of can be 2°≤η 2 ≤10°. In other examples, η 2 The value range of can also be 2°≤η 2≤5°. Generally, when the tilt angle is too large, the water flow rate will be too high, and the condensed water will easily splash out during the outflow process, thus affecting the overall performance of the base and its air conditioner; when the tilt angle is too small, the water flow rate will be too low, thus affecting the condensed water discharge efficiency. Therefore, by setting the angle between the water guide slope and the horizontal plane within a certain range, the condensed water discharge efficiency can be guaranteed without splashing out the condensed water, thus improving the smoothness and stability of the condensed water discharge.

[0191] In addition, in this embodiment, if Figure 27 to Figure 29 As shown, the drain pipe 420 can be a hollow tubular structure. In some examples, the drain pipe 420 can be a regular hollow tubular structure, such as a hollow round tubular structure, a hollow square tubular structure, etc., or an irregular hollow tubular structure or a combination of a regular hollow tubular structure and an irregular hollow tubular structure. In other examples, the diameter of the transition zone 412 can be the same as the diameter of the drain pipe 420. In this case, the effectiveness of the transition zone and the drain pipe can be further improved to comprehensively reduce obstacles that affect the water flow rate when the two are connected, such as grooves or convex edges, thereby further improving the smoothness of the connection between the transition zone and the drain pipe, further improving the smoothness of drainage, and more conducive to improving drainage efficiency, ensuring the thoroughness of drainage, and preventing water from remaining in the chassis structure and affecting the overall performance of the air conditioner.

[0192] In addition, a water plug is usually installed at the outlet of the drain pipe to block the drain pipe 420. When drainage is required, the water plug is pulled out. In the chassis structure provided by the present invention, the drain pipe 420 is connected to the side wall of the transition zone 412. The drain pipe 420 is connected to the right side wall of the transition zone 412, so that the drain pipe 420 is exposed to the outside of the air conditioner. In this case, the drain pipe is arranged on the side wall of the transition zone, which is convenient for the installation and removal of the water plug on the drain pipe, and at the same time, it can also avoid the phenomenon of excessive water outflow.

[0193] In this embodiment, the size of the drain pipe 420 is not particularly limited. In some examples, the diameter of the inner wall 421 of the drain pipe 420 can be gradually increased along the outflow direction of water in the drain pipe 420. In other examples, there is a height difference between the side where the drain pipe 420 is connected to the transition zone 412 and the side away from the transition zone 412. Since the drain pipe 420 is connected to the side wall of the transition zone 412, that is, if the side wall is vertical, the axis of the drain pipe 420 is in a horizontal state, and since the diameter of the inner wall 421 of the drain pipe 420 can be gradually increased, the side where the water flows into the drain pipe is higher than the side where the water flows out of the drain pipe along the outflow direction of the water, thereby increasing the outflow speed of the condensed water in the drain pipe and further ensuring the thoroughness of the drainage of the chassis structure.

[0194] In addition, in the present embodiment, there is no particular limitation on the numerical value of the height difference between the side where the drain pipe 420 is connected to the transition zone 412 and the side away from the transition zone 412. In some examples, the height difference can be 2 to 6 mm, such as 3 mm, 4 mm or 5 mm. In general, when the height difference is too large, the inclination angle of the drain pipe will be too large, which will cause the water flow rate to be too large, and it is easy to cause rapid outflow during the outflow of condensed water, which will bring certain pressure to the collection or discharge of condensed water; and when the height difference is too small, the inclination angle of the drain pipe will be too small, which will cause the water flow rate to be too small, thereby affecting the discharge efficiency of condensed water. Therefore, by setting the height difference on both sides of the drain pipe within a certain range, the discharge efficiency of condensed water can be guaranteed, and the situation of rapid outflow of condensed water will not occur, thereby improving the smoothness and stability of condensed water discharge.

[0195] In this embodiment, if Figure 27 to Figure 29 As shown, the edge of the outlet of the drain pipe 420 may be provided with a notch 422. In some examples, the notch 422 may be a depression on one side facing the transition zone 412. Since the drain pipe 420 is connected to the side wall of the transition zone 412, that is, if the side wall is vertical, the axis of the drain pipe 420 is in a horizontal state. At this time, the notch 422 is located at the lower end of the edge of the drain pipe 420, that is, the notch 422 is located at the lowest point of the edge of the outlet of the drain pipe 420. Generally, when the water in the drain pipe is discharged to a relatively low water level, the water will not be able to continue to flow due to its own stress when it is at a height of 3 to 5 mm. Therefore, by providing a notch at the outlet edge of the drain pipe, the stress of the water itself can be effectively eliminated, and shear force can be provided to the water so that it can continue to flow, so as to improve the thoroughness of the water discharge in the drain pipe.

[0196] In addition, in this embodiment, the shape of the notch 422 is not particularly limited. In some examples, the notch 422 can be a regular shape, such as a triangle, a semicircle, a polygon, etc., or an irregular shape or a combination of a regular shape and an irregular shape. Therefore, the setting of notches of different shapes can be adjusted according to actual needs to improve the overall applicability of the air conditioner.

[0197] In addition, in this embodiment, there is no particular limitation on the number of the notches 422. In some examples, the notches 422 may be more than one, such as two, three, or four. In this case, the stress of the water itself can be further eliminated, further improving the thoroughness of the water discharge in the drain pipe.

[0198] In this embodiment, the drainage area 400 may also be provided with a drainage area reinforcement rib 413. In some examples, the drainage area reinforcement rib 413 may be provided on the water guide area 411. In other examples, the drainage area reinforcement rib 413 may be located on the side where the drain pipe 420 is connected to the transition area 412. In this case, by providing the drainage area reinforcement rib, a connection can be formed between the water guide area and the drain pipe, and the stability of the connection can be improved, so as to improve the stability of the chassis structure and the air conditioner, extend its service life, etc.; and the provision of the drainage area reinforcement rib also has a certain windproof effect, so as to effectively avoid the occurrence of air leakage of the air conditioner, etc., and improve the comfort of the air conditioner.

[0199] In addition, in this embodiment, there is no particular limitation on the number of the drainage area reinforcement ribs 413. In some examples, the number of the drainage area reinforcement ribs 413 may be more than one, such as two, four, or five. Thus, different numbers of drainage area reinforcement ribs may be provided according to the number of water guide areas, thereby improving the overall stability of the chassis structure.

[0200] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made by any technical personnel in this field within the spirit and principles of the present invention should be included in the protection scope of the present invention.
