Description

Technical Field

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

[0002] With the continuous improvement of people's living standards, air conditioners have been widely used.

[0003] The existing air conditioner includes a chassis and a heat exchanger. The heat exchanger is installed on the chassis, and a main water collection tank and a side water collection tank are provided at the installation position of the heat exchanger on the chassis. During the operation of the air conditioner, the heat exchanger will produce a large amount of condensed water, which will drip into the main water collection tank and the side water collection tank of the chassis. The side water collection tank is provided with a water outlet, and the condensed water flows from the water outlet of the side water collection tank to the main water collection tank. In the existing air conditioner, the air in the heat exchanger easily enters the side water collection tank from the water outlet of the side water collection tank, causing part of the air intake of the heat exchanger to be lost, affecting the heat exchange efficiency of the heat exchanger.

[0004] It can be seen that developing an air conditioner chassis that can effectively solve the above problems is a technical problem that urgently needs to be solved. Summary of the invention

[0005] The problem solved by the invention is that in the existing air conditioner, the air in the heat exchanger is easily lost from the water outlet of the side water collecting tank of the chassis, thus affecting the heat exchange efficiency of the heat exchanger.

[0006] In order to solve the above-mentioned problem, the present invention provides an air conditioner chassis for installing a heat exchanger, wherein a water storage area is provided on the chassis, and the water storage area is located on one side of the heat exchanger in the assembled state, and a water passing notch and a wind shield structure are provided on the side of the water storage area close to the heat exchanger, and the wind shield structure is suitable for preventing air from the direction of the heat exchanger from entering the water storage area through the water passing notch in the assembled state.

[0007] 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 heat exchanger in the assembled state; on the other hand, it can also prevent the air in the heat exchanger from entering the water storage area through the water gap, thereby preventing air leakage and improving the working efficiency of the heat exchanger.

[0008] 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.

[0009] In this way, when the air in the heat exchanger 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 heat exchanger.

[0010] 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.

[0011] In this way, the third wind shield rib divides the water gap into two, so that the airflow flowing from the water gap into the water storage area is diverted at the water gap, reducing the flow rate of the airflow. According to Bernoulli's principle, the pressure will increase when the flow rate of the airflow decreases, and the resistance will be greater when the airflow flows to the water storage area, further reducing the air leakage of the heat exchanger. 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.

[0012] 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.

[0013] 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.

[0014] Optionally, the water storage area has a first side wall in its length direction, the first side wall is a V-shaped structure, the opening of the V-shaped structure is toward the side of the water storage area away from the heat exchanger, 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.

[0015] 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.

[0016] Optionally, the V-shaped structure of the first side wall has a first side edge and a second side edge at the front and rear ends of the water passing gap, respectively, and the inclination angle α1 of the first side edge relative to the front-to-back direction is between 5°-10°, and / or the inclination angle α2 of the second side edge relative to the front-to-back direction is between 5°-10°.

[0017] Within this angle range, the water storage area has better comprehensive performance in terms of water storage capacity and diversion effect, which can ensure that the water storage area not only has sufficient water storage area to prevent air conditioner leakage without affecting other structures of the chassis, but also ensures that the first side wall has a diversion function and good drainage effect.

[0018] Optionally, the first wind shielding rib and the second wind shielding rib are arranged at an angle, and the free ends of the first wind shielding rib and the second wind shielding rib are close to the first side wall, suitable for guiding condensed water to flow toward the first side wall.

[0019] In this way, it is possible to avoid condensation water being blocked by the first wind shield rib plate and the second wind shield rib plate on the side away from the water passing gap, so that the condensation water dripping into the water storage area flows along the first wind shield rib plate and the second wind shield rib plate to the first side wall, and then flows along the first side wall to the water passing gap, thereby achieving better diversion effect and improving the drainage effect of the water storage area.

[0020] Optionally, the inclination angle α3 of the first wind shielding rib relative to the front-rear direction is between 15° and 30°, and / or the inclination angle α4 of the second wind shielding rib relative to the front-rear direction is between 15° and 30°.

[0021] In this way, within this angle range, it is ensured that the first wind shield rib plate and / or the second wind shield rib plate has a certain guiding effect, and it is also ensured that the condensed water can flow smoothly from the water passing area formed between the free end of the first wind shield rib plate and / or the second wind shield rib plate and the first side wall to the water passing gap, thereby achieving a better drainage effect.

[0022] Optionally, one end of the third wind shield rib extends to the water passing notch, and the other end of the third wind shield rib extends to a side of the water storage area away from the heat exchanger, and divides the water storage area into a first water storage tank and a second water storage tank, and the bottom surface of the first water storage tank and the bottom surface of the second water storage tank have a side away from the third wind shield rib higher than a side connected to the third wind shield rib, and are suitable for guiding condensed water to flow toward the third wind shield rib.

[0023] In this way, the speed at which condensed water flows in the first water tank and the second water tank to the third wind shield rib is increased, so that the condensed water can be discharged from the water storage area faster and the condensed water is discharged more cleanly, preventing the condensed water from being retained in the first water tank and the second water tank to form accumulated water, thereby further improving the drainage efficiency and drainage effect of the water storage area.

[0024] Optionally, the angle α5 between the bottom surface of the first water storage tank and the horizontal plane is between 2°-5°, and / or the angle α6 between the bottom surface of the second water storage tank and the horizontal plane is between 2°-5°.

[0025] In this way, within this angle range, not only can the bottom surfaces of the first water tank and the second water tank have good diversion effects, but also sufficient height between the bottom surface of the water storage area and the ground can be ensured, so that the air conditioner can be moved and transported smoothly.

[0026] Optionally, the side of the bottom surface of the first water storage tank and the bottom surface of the second water storage tank away from the water passing gap is higher than the side where the water passing gap is located, which is suitable for guiding condensed water to flow toward the water passing gap.

[0027] In this way, the flow rate of the condensed water in the first water tank and the second water tank is increased, so that the condensed water can be discharged from the water storage area faster and the condensed water is also discharged more cleanly, preventing the condensed water from being retained in the first water tank and the second water tank, forming stagnant water and corroding the chassis. This not only further improves the drainage efficiency and drainage effect of the water storage area, but also improves the quality of the chassis and extends the service life of the chassis.

[0028] Optionally, the intersection line formed by the intersection of the bottom surface of the first water storage tank 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 storage tank and the plane perpendicular to the front-to-back direction has an inclination angle of 2°-5° relative to the left-to-right direction.

[0029] Within this angle range, not only can the bottom surfaces of the first water tank and the second water tank have good diversion effects, but also sufficient height between the bottom surface of the water storage area and the ground can be ensured, so that the air conditioner can be moved and transported smoothly.

[0030] Optionally, the water storage area has a second side wall in its length direction, and a reinforcement structure is provided on the second side wall.

[0031] In this way, the structural strength of the second side wall on the water storage area can be enhanced, thereby improving the strength of the chassis, so that the water storage area of ​​the chassis is not easily deformed when subjected to vibration, shock or impact during transportation or operation of the air conditioner, thereby improving the use quality of the chassis.

[0032] Optionally, a plurality of reinforcing structures are provided and are distributed at equal intervals on the second side wall.

[0033] In this way, by further enhancing the structural strength of the second side wall, the strength and quality of the left side wall of the chassis are improved, thereby extending the service life of the chassis.

[0034] In order to solve the above problems, the present invention further provides an air conditioner, comprising any of the above-mentioned air conditioner chassis.

[0035] The advantages of the air conditioner and the above-mentioned air conditioner chassis over the prior art are the same, which will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0049] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0050] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “up”, “down”, “left”, “right”, “high” and “low” are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0051] In the prior art, a main water collecting tank and a side water collecting tank are provided at the installation position of the heat exchanger on the chassis, and no structure is provided in the side water collecting tank to prevent the air in the heat exchanger from entering the side water collecting tank, wherein the main water collecting tank is equivalent to the main water collecting area 100 in the present invention, and the side water collecting tank is equivalent to the water storage area 200 in the present invention. Based on the prior art, the present invention provides a wind shielding structure 210 in the water storage area 200, and improves the structure of the water storage area 200.

[0052] Combination Figures 1 to 4 As shown, this embodiment provides an air conditioner chassis for installing a heat exchanger 10, and a water storage area 200 is provided on the chassis. The water storage area 200 is located on one side of the heat exchanger 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 heat exchanger 10. The wind shield structure 210 is suitable for blocking air from the direction of the heat exchanger 10 from entering the water storage area 200 through the water passing notch 221 in the assembled state.

[0053] 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 heat exchanger 10 is assembled on the chassis, the main water collection area 100 is located below the heat exchanger 10, the water storage area 200 is located on the left side of the heat exchanger 10, and the wind shielding structure 210 abuts against the bracket 11 on the left side of the heat exchanger 10, so that the wind shielding structure 210 can provide support for the heat exchanger 10. When the air conditioner is working, the heat exchanger 10 will produce a large amount of condensed water, most of which will drip into the main water collection area 100 along the heat exchanger 10, and a small part will drip into the water storage area 200 along the bracket 11 on the left side of the heat exchanger 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 pumping area on the chassis, and is atomized by the water pumping motor installed in the water pumping area, thereby evaporating the condensed water. In the prior art, the air blown into the heat exchanger 10 circulates inside the heat exchanger 10 to perform heat exchange, and the air circulating inside the heat exchanger 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. Since the main water collection area 100 is located on the right side of the water storage area 200 and is also located below the heat exchanger 10, the air flowing from the main water collection area 100 into the water storage area 200 is equivalent to the air from the direction of the heat exchanger 10. In the absence of a wind shielding structure 210, the air in the heat exchanger 10 enters the water storage area 200 from the water gap 221 without any hindrance, resulting in air leakage in the heat exchanger 10 area, affecting the heat exchange efficiency of the heat exchanger 10. In this embodiment, a wind shield structure 210 is set in the water storage area 200, so that the air from the direction of the heat exchanger 10, that is, 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 obstruction of the wind shield structure 210, and most of it will flow back into the main water collection area 100.

[0054] 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 heat exchanger 10 in the assembled state; on the other hand, it can also prevent the air in the heat exchanger 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 heat exchanger 10.

[0055] Optional, combined Figure 1 and Figure 2 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 .

[0056] 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. The water-passing gap 221 has two sides in the front-to-back direction, which are respectively referred to as the front side and the rear side for ease of understanding, and the front side and the rear side of the water-passing gap 221 can form a plane, which is the plane where the water-passing gap 221 is located. In other words, the projection of the first wind shielding rib 211 on the plane where the water-passing gap 221 is located is the first projection, and the projection of the second wind shielding rib 212 on the plane where the water-passing gap 221 is located is the second projection. The first projection and the second projection can intersect or be connected at the edge of the projection. The projection of the first wind shielding rib 211 and the second wind shielding rib 212 on the plane where the water-passing 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-passing gap 221, and can completely cover the water-passing gap 221. It should be noted that when the first projection and the second projection intersect, the first projection area is added to the second projection area, 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.

[0057] In this way, when the air in the heat exchanger 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 heat exchanger 10.

[0058] Optional, combined Figure 7 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.

[0059] 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.

[0060] 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 heat exchanger 10.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] Optionally, the areas of the first notch 2211 and the second notch 2212 are equal.

[0065] 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.

[0066] In this way, after the airflow flowing into the water storage area 200 through the water passing notch 221 is split at the water passing notch 221, the pressures at the first notch 2211 and the second notch 2212 are the same, and the obstruction effects on the airflow are also equivalent, thereby avoiding the situation where one of the two notches obstructs the airflow much less than the other notch, causing most of the airflow blowing toward the water passing notch 221 to flow into the water storage area 200 from the notch with less obstruction, thereby further reducing air leakage of the heat exchanger 10.

[0067] Optional, combined Figure 5As 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 heat exchanger 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.

[0068] 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 heat exchanger 10 and the main water collection area 100 are located on the right side of the water storage area 200, and the first side wall 220 is arranged close to the heat exchanger 10, the first side wall 220 is located on the left side of the heat exchanger 10, that is, the V-shaped structure is located on the left side of the heat exchanger 10 and close to the heat exchanger 10, and the condensed water dripping into the water storage area 200 flows from the water storage area 200 to the main water collection area 100, so the opening of the V-shaped structure of the first side wall 220 faces left and the top faces right.

[0069] 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.

[0070] Optional, combined Figure 5 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 .

[0071] 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.

[0072] 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.

[0073] 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.

[0074] Optionally, a plurality of reinforcing structures 231 are provided and are evenly spaced and distributed on the second side wall 230 .

[0075] 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.

[0076] 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.

[0077] Optional, combined Figure 6 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°.

[0078] 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. Figure 5 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.

[0079] 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.

[0080] Optional, combined Figure 6 and Figure 7 As 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 .

[0081] 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.

[0082] 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.

[0083] Optional, combined Figure 7 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°.

[0084] 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. Figure 7 As 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.

[0085] 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.

[0086] Optional, combined Figure 5 and Figure 8 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 heat exchanger 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.

[0087] 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 heat exchanger 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 tanks, namely the first water tank 240 and the second water tank 250. The first water tank 240 is located at the front end of the third wind shield rib 213, and the second water 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.

[0088] 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.

[0089] Optional, combined Figure 8 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°.

[0090] 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.

[0091] 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.

[0092] Optional, combined Figures 9 to 11 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.

[0093] 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.

[0094] 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.

[0095] Optional, combined Figures 9 to 11 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.

[0096] 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.11 There is a diagonal line segment in the middle. Fig.11 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.

[0097] 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.

[0098] This embodiment also provides an air conditioner to solve the problem in existing air conditioners that the air in the heat exchanger is easily lost from the water outlet of the side water collecting tank of the chassis, affecting the heat exchange efficiency of the heat exchanger. The air conditioner includes any of the above-mentioned air conditioner chassis.

[0099] The air conditioner in this embodiment is provided with a water-passing notch 221 and a wind-shielding structure 210 on the water storage area 200 of the chassis, and the wind-shielding structure 210 is located on the left side of the heat exchanger 10 in the assembled state. In this way, on the one hand, the structural strength of the water storage area 200 is enhanced, and a supporting force can be provided to the heat exchanger 10 in the assembled state; on the other hand, the air in the heat exchanger 10 can be prevented from entering the water storage area 200 through the water-passing notch 221, thereby playing a role in preventing air leakage and improving the working efficiency of the heat exchanger 10.

[0100] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
