Description

Technical Field

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

[0002] Under normal circumstances, the condensed water generated inside the mobile air conditioner is consumed by itself. However, when the air humidity is too high, the rate at which the condensed water is consumed cannot keep up with the rate at which the condensed water is generated. The water storage structure of the traditional chassis is single, and water is only stored in one water collection area, with poor water storage capacity. Therefore, it is necessary to increase the water storage capacity of the chassis.

[0003] This shows that the structure of existing mobile air conditioners needs further improvement. Summary of the invention

[0004] The problem solved by the present invention is that the existing mobile air conditioner stores water only through one water collection area and has poor water storage capacity.

[0005] In order to solve the above problems, the present invention provides a chassis water storage structure, comprising a main water collection area, a first water storage area, a second water storage area and a drainage area, wherein the main water collection area is connected to the first water storage area, the second water storage area and the drainage area respectively;

[0006] When the chassis is placed horizontally, in the direction of gravity, the main water collection area intersects with the drainage area, the second water storage area, and the first water storage area respectively, and the vertical heights at the intersections are higher than the bottom surface of the main water collection area; and there is a height difference between the main water collection area and the drainage area, the second water storage area, and the first water storage area at each of the intersections.

[0007] According to the chassis water storage structure of the present invention, after the condensed water on the heat exchanger falls into the main water collection area, as the water level rises, it enters the drainage area, the second water storage area, and the first water storage area, thereby forming a four-stage water storage.

[0008] Optionally, the vertical height differences between the main water collection area and the drainage area, the second water storage area, and the first water storage area at the intersections increase successively.

[0009] In the chassis water storage structure described in the present invention, after the condensed water on the heat exchanger falls into the main water collection area, as the water level increases, it first flows into the drainage area, then into the second water storage area, and finally into the first water storage area, thereby forming a four-stage water storage.

[0010] Optionally, in the left-right direction, the main water collection area is connected with the first water storage area on the left side; the main water collection area is connected with the second water storage area and the drainage area on the right side, and in the front-back direction, the second water storage area and the drainage area are respectively located on the front and rear sides of the main water collection area.

[0011] The chassis water storage structure of the present invention facilitates uniform water storage in the chassis by reasonably distributing the first water storage area, the second water storage area, the drainage area and the main water collection area.

[0012] 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.

[0013] The air conditioner chassis water storage structure of the present invention is beneficial to realizing the water collection function of the main water collection area by designing the convergence part as a concave structure.

[0014] Optionally, the converging portion includes four converging surfaces, and the four converging surfaces intersect at the converging point.

[0015] The air conditioner chassis water storage 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.

[0016] 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.

[0017] The air conditioner chassis water storage structure of the present invention provides a guide bottom surface inclined toward the main water collection area in the second water storage area, so that condensed water in the second water storage area can flow smoothly to the main water collection area.

[0018] Optionally, the second water storage area further includes a guide side surface, which is located on a side of the guide bottom surface adjacent to the drainage area in the left-right direction, and an angle β of the guide side surface relative to the front-rear direction is in the range of 5-10 degrees.

[0019] The air conditioner chassis water storage 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.

[0020] 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 direction of the heat exchanger from entering the first water storage area through the water gap in an assembled state.

[0021] The air conditioner chassis water storage structure described in the present invention and the arrangement of the wind shield structure, on the one hand, strengthen the structural strength of the first 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 first water storage area through the water passing gap, thereby playing a role in preventing air leakage and improving the working efficiency of the heat exchanger.

[0022] 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.

[0023] According to the air conditioner chassis water storage structure of the present invention, when the air in the heat exchanger is blown into the water storage area through the water passing gap, all the air can be blown onto the wind shield structure, and most of it can 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.

[0024] 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.

[0025] In the water storage structure of the air conditioner chassis described in the present invention, the third wind shield rib divides the water gap into two, so that the airflow flowing from the water gap into the first water storage area is split 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 of the airflow when it flows to the first water storage area will be greater, further reducing air leakage of the heat exchanger; at the same time, the fishbone structure of the wind shield structure can ensure that the first water storage area is not prone to shrinkage during injection molding of the chassis, thereby improving the manufacturing quality of the chassis.

[0026] 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.

[0027] The air conditioner chassis water storage structure of the present invention can ensure that the first water storage area is not prone to shrinkage during the chassis injection molding through the above arrangement, thereby improving the manufacturing quality of the chassis.

[0028] 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 first 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.

[0029] According to the air conditioner chassis water storage structure described in the present invention, condensed water dripping into the first water storage area can flow along the first side wall to the water passing gap, so that the first side wall has a diversion effect, preventing condensed water from being retained in the first water storage area, thereby improving the drainage effect of the chassis.

[0030] Optionally, the first wind shielding rib plate and the second wind shielding rib plate are arranged at an angle, and the free ends of the first wind shielding rib plate and the second wind shielding rib plate are close to the first side wall, suitable for guiding condensed water to flow toward the first side wall.

[0031] The air conditioner chassis water storage structure described in the present invention can prevent condensed water from 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 through the above-mentioned arrangement, so that the condensed water dripping into the first 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 a better diversion effect and improving the drainage effect of the first water storage area.

[0032] The present invention also provides an air conditioner, comprising the chassis water storage structure described in any of the above paragraphs. The air conditioner of the present invention has the same beneficial effects as the chassis water storage structure over the prior art, which will not be described in detail here.

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 terminology nouns in the various embodiments, such as "up", "down", "left", "right", "outside", "inside", etc., which indicate directions, are only for simplifying the description of the positional relationship based on the drawings in the specification, and do not mean that the referred elements and devices must be operated according to the specific directions and defined operations and methods and structures in the specification. Such directional nouns do not constitute limitations to the present invention.

[0051] In addition, the terms "first" and "second" mentioned in the embodiments of the present invention are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0052] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0053] like Figure 1 As shown, a chassis water storage structure includes a main water collection area 100, a first water storage area 200, a second water storage area 300 and a drainage area 400, and the main water collection area 100 is connected to the first water storage area 200, the second water storage area 300 and the drainage area 400 respectively;

[0054] When the chassis is placed horizontally, in the direction of gravity, the main water collection area 100 intersects with the drainage area 400, the second water storage area 300, and the first water storage area 200 respectively, and the vertical heights at the intersections are higher than the bottom surface of the main water collection area 100; and the main water collection area 100 and the drainage area 400, the second water storage area 300, and the first water storage area 200 have height differences in the vertical heights at each of the intersections.

[0055] In the chassis water storage structure described in the present invention, after the condensed water on the heat exchanger falls into the main water collection area 100, as the water level increases, it then flows into the drainage area 400, the second water storage area 300, and the first water storage area 200, thereby forming a four-stage water storage.

[0056] The vertical height differences at the intersections of the main water collection area 100 with the drainage area 400 , the second water storage area 300 , and the first water storage area 200 increase in sequence.

[0057] In the chassis water storage structure described in the present invention, after the condensed water on the heat exchanger falls into the main water collection area 100, as the water level increases, it first flows into the drainage area 400, then flows into the second water storage area 300, and finally flows into the first water storage area 200, thereby forming a four-stage water storage.

[0058] In the left-right direction, the main water collection area 100 is connected to the first water storage area 200 on the left; the main water collection area 100 is connected to the second water storage area 300 and the drainage area 400 on the right, and in the front-back direction, the second water storage area 300 and the drainage area 400 are respectively located on the front and rear sides of the main water collection area 100.

[0059] The chassis water storage structure of the present invention facilitates uniform water storage in the chassis by reasonably distributing the first water storage area 200, the second water storage area 300, the drainage area 400 and the main water collection area 100.

[0060] The first water storage area 200 is higher than the main water collection area 100. Figure 2 and Figure 3 As shown, “higher than” is defined as: the lowest point of the first water storage area 200 is higher than the highest point of the convergence portion 110 in the main water collection area 100, so that the condensed water of the air conditioner mainly enters the main water collection area 100, and the first water storage area 200 receives a small amount of condensed water.

[0061] 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 heat exchanger of the air conditioner. The condensed water of the air conditioner mainly enters the main water collection area 100 from the heat exchanger. The first water storage area 200 receives a small amount of condensed water. When the water level of the main water collection area 100 is not higher than that of the first water storage area 200, the water of the first water storage area 200 flows to the main water collection area 100, and the water of the main water collection area 100 enters the water pumping trough 700. Driven by the water pumping motor, the water in the water pumping trough 700 is pumped to the heat exchanger. At the same time, the water pumping motor shaft will bring the water into the water pumping motor area 600, and finally flow to the drainage area 400; when the water level of the main water collection area 100 is higher than that of the first water storage area 200, the first water storage area 200 plays a certain water storage function.

[0062] The chassis water storage structure described in the present invention, by setting the first water storage area 200 higher than the main water collection area 100, 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 common water storage in the main water collection area 100 and the first water storage area 200 when the water volume is large.

[0063] Optionally, combined Figure 2-Figure 4 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.

[0064] Specifically, combined Figure 4 As shown, the converging portion 110 is generally concave in shape, similar to a funnel-shaped structure, wherein: Figure 4 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.

[0065] The air conditioner chassis water storage structure of the present invention is beneficial to realizing the water collection function of the main water collection area 100 by designing the convergence portion 110 as a concave structure.

[0066] Optionally, combined Figure 3 and Figure 4 As shown, the converging portion 110 includes four converging surfaces 111 , and the four converging surfaces 111 intersect at a converging point 112 .

[0067] 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.

[0068] The air conditioner chassis water storage structure of the present invention can converge the condensed water in the main water collection area 100 to the convergence point by setting the convergence point.

[0069] Optionally, the angle γ between the converging surface 111 and the horizontal plane ranges from 2 to 4 degrees.

[0070] Specifically, combined Figure 4 As 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 4 As shown, Figure 4 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.

[0071] The air conditioner chassis water storage structure of the present invention effectively ensures the effective collection and discharge process of condensed water by setting the angle γ between the convergence surface 111 and the horizontal plane to be in the range of 2 to 4 degrees.

[0072] Optionally, the air conditioner chassis water storage structure further includes a water tank 700 , and the convergence point 112 is located at a notch 710 of the water tank 700 .

[0073] Combination Figure 3 and Figure 4 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 heat exchanger 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.

[0074] The air conditioner chassis water storage structure described in the present invention sets a convergence point at the notch of the water tank 700 so that condensed water can flow smoothly into the water tank 700 .

[0075] Optionally, the air conditioner chassis water storage structure further includes a water level switch area 500 , and a connecting port 510 is provided at the connection between the water level switch area 500 and the main water collection area 100 .

[0076] Specifically, combined Figure 1-Figure 3 As shown, the chassis water storage structure includes a water level switch area 500. The water level switch area 500 determines whether the condensed water has a tendency to overflow the chassis by detecting the water level. When the condensed water has a tendency to overflow the chassis because the amount of water produced is greater than the amount of water consumed, that is, when the water level reaches the warning height, the water level switch turns off the compressor and increases the consumption rate of the condensed water. A connecting port 510 is provided at the connection between the water level switch area 500 and the main water collection area 100, so that the water level switch area 500 can monitor the water level of the main water collection area 100. When there is too much condensed water in the main water collection area 100, the water level in the water level switch area 500 reaches the warning height, and the water level switch turns off the compressor and increases the consumption rate of the condensed water, thereby ensuring that the condensed water in the chassis will not overflow.

[0077] The chassis water storage structure described in the present invention provides a connecting port 510 at the connection between the water level switch area 500 and the main water collection area 100, so that the water level switch area can monitor the water level of the main water collection area, thereby preventing condensed water in the chassis from overflowing.

[0078] Optionally, combined Figure 2 and Figure 3 As shown, the main water collection area 100 further includes a wind shielding rib 120 , and the wind shielding rib 120 is arranged opposite to the connecting port 510 .

[0079] Specifically, the main water collection area 100 and the water level switch area 500 are connected through the connecting port 510. The connecting port 510 mainly serves to receive the water flow. However, it is not only condensed water that passes through the connecting port 510, but also air leakage. Therefore, the wind shield 120 is arranged opposite to the connecting port 510 to reduce the air leakage at the connecting port 510 without affecting the flow of water.

[0080] The air conditioner chassis water storage structure described in the present invention reduces air leakage at the connecting port 510 without affecting the flow of water by arranging the wind shield 120 and the connecting port 510 relatively.

[0081] Optionally, combined Figure 3 As shown, there are three wind shielding ribs 120, and the three wind shielding ribs 120 are distributed in a herringbone structure.

[0082] Specifically, the three wind shielding ribs 120 are as follows: Figure 3 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.

[0083] The air conditioner chassis water storage structure of the present invention reduces the probability of air leakage without affecting the flow direction of water by arranging three wind shielding ribs 120 in a herringbone structure.

[0084] Optionally, the first water storage area 200 is provided with a water gap 221 and a wind shielding structure 210 , and the wind shielding structure 210 is suitable for preventing air from the direction of the heat exchanger from entering the first water storage area 200 through the water gap 221 in the assembled state.

[0085] The chassis is provided with a main water collection area 100 and a first water storage area 200, which are connected at a water gap 221, and a wind shielding structure 210 is arranged in the first water storage area 200 near the water gap 221. When the heat exchanger is assembled on the chassis, the main water collection area 100 is located below the heat exchanger, the first water storage area 200 is located on the left side of the heat exchanger, and the wind shielding structure 210 abuts against the bracket on the left side of the heat exchanger, so that the wind shielding structure 210 can provide support for the heat exchanger. When the air conditioner is working, the heat exchanger will produce a large amount of condensed water, most of which will drip into the main water collection area 100 along the heat exchanger, and a small part will drip into the first water storage area 200 along the bracket on the left side of the heat exchanger. This small part of condensed water is collected in the first 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 700 on the chassis, and is hit by the water motor installed in the water trough 700 to be atomized and hit the hot heat exchanger, thereby evaporating the condensed water. In the prior art, the air blown into the heat exchanger circulates inside the heat exchanger to perform heat exchange, and the air circulating inside the heat exchanger will also flow in the main water collection area 100. However, since the main water collection area 100 is connected to the first water storage area 200 at the water gap 221, the air flowing in the main water collection area 100 will flow into the first water storage area 200 from the water gap 221. In the absence of a wind shield structure 210, the air in the heat exchanger enters the first water storage area 200 from the water gap 221 without any hindrance, resulting in air leakage in the heat exchanger area, affecting the heat exchange efficiency of the heat exchanger. In this embodiment, a wind shield structure 210 is provided in the first 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 first water storage area 200 due to the hindrance of the wind shield structure 210, and most of it will flow back into the main water collection area 100.

[0086] The chassis water storage structure and the wind shield structure 210 described in the present invention can, on the one hand, strengthen the structural strength of the first water storage area 200 and 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 first water storage area 200 through the water gap 221, thereby preventing air leakage and improving the working efficiency of the heat exchanger.

[0087] Optionally, 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 .

[0088] 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.

[0089] With the air conditioner chassis water storage structure described in the present invention, when the air in the heat exchanger is blown into the first water storage area 200 through the water passing gap 221, all of the air 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.

[0090] Optionally, 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.

[0091] The third wind shield rib 213 is arranged in the first 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.

[0092] In the chassis water storage structure described in the present invention, the third wind shield rib 213 divides the water gap 221 into two, so that the airflow flowing into the first 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, the pressure of the airflow increases when the flow rate of the airflow decreases, and the resistance of the airflow when it flows to the first water storage area 200 is greater, further reducing air leakage of the heat exchanger.

[0093] 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.

[0094] Specifically, that is to say, the windshield structure 210 is a fishbone structure, wherein the third windshield rib plate 213 constitutes a main structure of the fishbone, and the first windshield rib plate 211 and the second windshield rib plate 212 constitute side branch structures on both sides of the main structure of the fishbone.

[0095] The herringbone structure of the windshield structure 210 can ensure that the first water storage area 200 is not prone to shrinkage during the injection molding of the chassis, thereby improving the manufacturing quality of the chassis.

[0096] Optionally, the areas of the first notch 2211 and the second notch 2212 are equal.

[0097] Specifically, 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.

[0098] In the air conditioner chassis water storage structure described in the present invention, after the airflow flowing into the first water storage area 200 through the water passing notch 221 is split at the water passing notch 221, the pressure at the first notch 2211 and the second notch 2212 are the same, and the obstruction effect on the airflow is 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 first water storage area 200 from the notch with less obstruction, thereby further reducing air leakage of the heat exchanger.

[0099] Optionally, combined Figure 5 As shown, the first 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 first water storage area 200 away from the heat exchanger. 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.

[0100] The size of the first water storage area 200 in the front-to-back direction is greater than its size in other directions, so the length direction of the first water storage area 200 is the front-to-back direction, the first side wall 220 is arranged on the first 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 and the main water collection area 100 are located on the right side of the first water storage area 200, the opening of the V-shaped structure of the first side wall 220 faces leftward and the top faces rightward.

[0101] According to the air conditioner chassis water storage structure described in the present invention, condensed water dripping into the first 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 first water storage area 200, thereby improving the drainage effect of the chassis.

[0102] Optionally, combined Figure 5 As shown, the first 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 .

[0103] Specifically, that is to say, the second side wall 230 is arranged on the first water storage area 200 along the front-to-back direction. The first water storage area 200 is a rectangular groove structure as a whole, 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 first 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 first water storage area 200 respectively. The reinforcement structure 231 is arranged on the second side wall 230 of the first water storage area 200. In this embodiment, the first water storage area 200 is arranged at the left end of the chassis, and the left side wall of the first 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.

[0104] The air conditioner chassis water storage structure described in the present invention can enhance the structural strength of the second side wall 230 on the first water storage area 200, thereby improving the strength of the chassis, so that during transportation or when the air conditioner is in operation, the first water storage area 200 of the chassis is not easily deformed when subjected to vibration, shock or impact, thereby improving the use quality of the chassis.

[0105] Optionally, the reinforcement structure 231 may be a plate-shaped structure, a block-shaped structure, a strip-shaped structure or other structures, which are not limited in detail in this embodiment.

[0106] Optionally, a plurality of reinforcing structures 231 are provided and are evenly spaced and distributed on the second side wall 230 .

[0107] 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.

[0108] The air conditioner chassis water storage structure of the present invention improves the strength and quality of the left side wall of the chassis by further enhancing the structural strength of the second side wall 230, thereby extending the service life of the chassis.

[0109] Optionally, 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°.

[0110] 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 the two line segments respectively constitute two sides of the V-shape, wherein the line segment located at the front end of the water-passing notch 221 constitutes the first side 222 of the V-shape, and the line segment located 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 gap 221 is also large. Due to the structural limitations 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 first water storage area 200, reduce the water storage capacity of the first water storage area 200, and cause the condensed water to overflow the chassis when the amount of condensed water generated increases, causing the air conditioner to leak.

[0111] In this embodiment, α1 and / or α2 are set between 5°-10°. Within this angle range, the comprehensive performance of the first water storage area 200 in terms of water storage capacity and diversion effect is better, which can ensure that the first 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.

[0112] Optionally, 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 .

[0113] Specifically, that is to say, the free ends of the first wind shielding rib 211 and the second wind shielding 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 shielding rib 213, and then from the front to the rear direction, the minimum distance between the first wind shielding rib 211 and the first side wall 220 after extension and located at the front end of the third wind shielding rib 213 gradually increases; the minimum distance between the second wind shielding rib 212 and the first side wall 220 after extension and located at the rear end of the third wind shielding rib 213 gradually decreases. In combination with the coordinate system in the figure, the first wind shielding rib 211 is inclined toward the right rear, and the second wind shielding rib 212 is inclined toward the right front.

[0114] The air conditioner chassis water storage structure described in the present invention can 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 first 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 first water storage area 200.

[0115] Optionally, 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°.

[0116] 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 first water storage area 200 and reducing the drainage effect of the first 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.

[0117] 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.

[0118] Combination 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, 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.

[0119] The main water collection area 100 is higher than the second water storage area 300. 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 lowest point of the main water collection area 100 at the connection is higher than the vertical height of the highest point of the bottom surface of the second water storage area 300, that is, at the connection, the main water collection area 100 and the second water storage area 300 form a step-like structure.

[0120] The second water storage area 300 is lower than the main water collection area 100. 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. Therefore, when the main water collection area 100 cannot consume all the condensed water through the water tank 700, this part of the condensed water is discharged through the drainage area 400.

[0121] Optionally, combined Fig.12 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 .

[0122] Specifically, the second water storage area 300 is located on the right side of the heat exchanger. The second water storage area 300 serves to increase the water storage capacity of the chassis. Therefore, a guide bottom surface 310 inclined toward the main water collection area 100 is provided 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.

[0123] The air conditioner chassis water storage structure described in the present invention provides a diversion 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.

[0124] Optionally, the angle between the guide bottom surface 310 and the horizontal plane is in the range of 2-5 degrees.

[0125] 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.

[0126] The air conditioner chassis water storage structure of 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.

[0127] Optionally, combined Fig.12 As shown, the second water storage area 300 further includes a guide side surface 320. In the left-right direction, the guide side surface 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 surface 320 relative to the front-back direction ranges from 5 to 10 degrees.

[0128] 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.

[0129] At the same time, the second water storage area 300 is also provided with wind-blocking ribs 330, which are located at the water outlet of the second water storage area 300. The wind-blocking ribs 330 mainly play the role of blocking airflow from blowing into the second water storage area 300 and reducing heat exchange losses of the heat exchanger.

[0130] The air conditioner chassis water storage 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.

[0131] In addition, combined Fig.13 and Fig.14 As shown, the air conditioner chassis water storage structure of the present invention includes a drainage area 400. The chassis water storage structure may include the drainage area 400 having a water guiding area 411 and a transition area 412, and a drainage pipe 420 connected to the transition area 412, wherein the water guiding area 411 and the transition area 412 may be connected, and the water guiding area 411 is suitable for introducing water into the transition area 412.

[0132] 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 may be formed between the water guide area and the drain pipe, and the stability of the connection may be improved, so as to improve the stability of the chassis and the air conditioner in use, 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 in use.

[0133] In addition, combined Fig.13 and Fig.14 As shown, along the outflow direction of water in the drain pipe 420, the diameter of the inner wall 421 of the drain pipe 420 can be gradually increased. 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 water flows into the drain pipe is higher than the side where water flows out of the drain pipe along the outflow direction of water, thereby increasing the outflow speed of condensed water in the drain pipe and further ensuring the thoroughness of chassis drainage.

[0134] The present invention also provides an air conditioner, comprising the chassis water storage structure described above. The chassis water storage structure has the same advantages as the chassis water storage structure of the air conditioner described above over the prior art, which will not be described in detail here.

[0135] 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.
