Description

Air conditioning three-box structure and automobile having the same Technical Field

[0001] The present application relates to the field of automobile control systems, and in particular to an air-conditioning three-box structure, and also to an automobile having the air-conditioning three-box structure. Background Art

[0002] The A / C unit is the core component of a vehicle's air conditioning system, providing cooling, heating, ventilation, and dehumidification functions. It can be divided into two parts: the left side houses the air conditioner, which contains the evaporator that performs the dehumidification function, and the right side houses the blower, which supplies air to the system. When the A / C unit's dehumidification function is engaged, water condenses on the evaporator's surface. Due to gravity, this condensation flows downward from the evaporator's surface, collecting in the water storage tank at the bottom of the air conditioner. From there, it flows out of the vehicle through a drain pipe at the bottom of the tank.

[0003] Under certain special driving conditions, such as when the vehicle decelerates sharply and makes a left turn while driving downhill, the water in the water tank is affected by centrifugal force (see figure), causing it to surge out of the tank and flow from the air conditioner to the blower. For the air conditioner and blower, which are two separate parts, the condensate flowing to the blower may flow through the gap at the connection between the air conditioner and the blower to outside the air conditioner and drip into the vehicle, causing user complaints, or flow into the blower, causing it to rust, produce abnormal noises, and shorten its lifespan. Existing technology addresses the problem of condensate overflow by increasing the depth of the water tank, but the deeper the tank, the more space it takes up inside the vehicle. Cars are small, and due to space constraints, the depth of the water tank that can be increased is limited, making it difficult to completely address the problem of condensate flowing to the blower due to centrifugal force.

[0004] Therefore, the present application provides an air-conditioning three-box structure and a car having the air-conditioning three-box structure to solve one of the above technical problems.

[0005] Summary of the Invention

[0006] The purpose of this application is to provide a three-box air conditioner structure and a vehicle having the same, which can solve at least one of the above-mentioned technical problems. The specific solution is as follows:

[0007] According to the specific implementation of the present application, in the first aspect, the present application provides an air-conditioning three-box structure, including: an air conditioner, an evaporator and a blower; a water storage tank is provided in the air conditioner, a drain pipe for discharging water is provided at the bottom of the water storage tank, a water flow channel is provided on the side of the water storage tank close to the blower, and a baffle No. 1, a baffle No. 2 and a baffle No. 3 are provided on the end of the water flow channel close to the blower to prevent water from flowing through, wherein the baffle No. 1 and the baffle No. 2 are respectively installed on the two side walls of the lower shell of the evaporator box relative to each other, and are arranged in a herringbone structure, and the baffle No. 3 is perpendicular to the water flow channel and is arranged at the connection between the air conditioner and the blower.

[0008] Preferably, the installation roots of the first baffle and the second baffle are symmetrical with respect to the water flow channel.

[0009] Preferably, the first baffle, the second baffle and the third baffle are of the same height.

[0010] Preferably, the width of the No. 1 baffle is 70% to 90% of the width of the channel at the installation location, and the angle with the water outflow direction is 70° to 75°; the width of the No. 2 baffle is 35% to 45% of the width of the channel at the installation location, and the angle with the water outflow direction is 105° to 110°.

[0011] Preferably, the width of the No. 1 baffle is 83% of the width of the channel at the installation location, and the angle with the water outflow direction is 73°; the width of the No. 2 baffle is 40% of the width of the channel at the installation location, and the angle with the water outflow direction is 107°.

[0012] Preferably, the invention further comprises a second baffle portion provided at the connection position between the first channel and the second channel of the water flow channel, wherein the second baffle portion is located on the side of the first baffle away from the blower.

[0013] Preferably, the second baffle portion includes a first baffle arranged on one side of the second channel and a second baffle arranged on the other side of the second channel.

[0014] Preferably, the width of the second baffle portion is 50% to 90% of the width of the water channel.

[0015] Preferably, a connecting plate integral with the first baffle is further provided at the connection between the first baffle and the wall, and the connecting plate is a triangular plate or a rectangular plate.

[0016] The three-box air conditioner structure of this application features baffles No. 1, No. 2, and No. 3 installed at the end of the water channel near the blower to prevent water from passing through. Baffles No. 1 and No. 2 are mounted on the two side walls of the lower shell of the evaporator box in a herringbone configuration. Baffle No. 3 is installed perpendicular to the water channel at the connection between the air conditioner and the blower. By using this water-retaining structure and placing a specially constructed water-blocking plate in the flow path of condensed water, condensed water is blocked within the air conditioner, preventing it from flowing into the blower or out of the three boxes, ensuring blower quality and improving the user experience.

[0017] In addition, a "human" shaped structure is used to prevent water from passing through. Assuming that the water passes through the "human", there is a No. 3 baffle to completely block the water flow. The "human" shaped structure can increase the resistance to water flowing outward and prevent water from flowing out to the greatest extent. At the same time, it has a smaller backflow resistance, so that the water passing through the "human" can easily flow back to the water storage tank.

[0018] Based on the above-provided three-box air-conditioning structure, according to the specific implementation of this application, in the second aspect, this application provides a car, including: an air-conditioning system, the three-box air-conditioning structure in the air-conditioning system is the three-box air-conditioning structure described in any one of the above-mentioned items.

[0019] Since the automobile provided in this application has the aforementioned three-box air conditioning structure, it also has the technical effects of the aforementioned three-box air conditioning structure. It can block condensation water within the air conditioner, preventing it from flowing into the blower or out of the three boxes, thereby ensuring the quality of the blower and improving the user's driving experience.

[0039] The embodiments of the present application are described in detail below with reference to FIG. 1 to FIG. 10 .

[0040] Example 1

[0041] The present embodiment provides a three-box air conditioner structure, comprising: an air conditioner, an evaporator, and a blower 1. The air conditioner is provided with a water tank 2, the bottom of which is provided with a drain pipe 3 for draining water. The water tank 2 has a water flow channel 4 on the side near the blower 1. The end of the water flow channel 4 near the blower 1 is provided with a first baffle 5, a second baffle 6, and a third baffle 7, which are used to prevent water from passing through. These baffles form a first baffle portion, as shown in Figures 1 to 4. Baffles 5 and 6 are mounted on the two side walls of the lower shell of the evaporator box, respectively, in a herringbone configuration. Baffle 7 is arranged perpendicular to the water flow channel 4 at the connection between the air conditioner and the blower 1, as shown in Figures 3 and 4.

[0042] Preferably, when the first baffle 5 and the second baffle 6 are installed, their installation roots fixed to the side wall of the shell are on a straight line perpendicular to the water flow channel 6 and symmetrical about the water flow channel 4, as shown in Figures 3 and 4.

[0043] By using the above-mentioned water retaining structure, a water blocking plate with a special structure is set on the flow path of the condensed water to block the condensed water inside the air conditioner, preventing it from flowing into the blower 1 or flowing out of the three boxes, thereby ensuring the quality of the blower 1 and improving the user experience.

[0044] Example 2

[0045] The present embodiment provides a three-box air conditioner structure, comprising: an air conditioner, an evaporator, and a blower 1. The air conditioner is provided with a water tank 2, the bottom of which is provided with a drain pipe 3 for draining water. The water tank 2 has a water flow channel 4 on the side near the blower 1. The end of the water flow channel 4 near the blower 1 is provided with a first baffle 5, a second baffle 6, and a third baffle 7 for preventing water from passing through, as shown in Figures 1 to 4. Baffles 1 and 2 are mounted on the two side walls of the lower shell of the evaporator box, respectively, in a herringbone configuration. Baffle 3 is arranged perpendicular to the water flow channel 4 at the connection between the air conditioner and the blower 1, as shown in Figures 3 and 4.

[0046] Preferably, when the first baffle 5 and the second baffle 6 are installed, their installation roots fixed to the side wall of the shell are on a straight line perpendicular to the water flow channel 6 and symmetrical about the water flow channel 4, as shown in Figures 3 and 4.

[0047] In a preferred embodiment, the first baffle 5, the second baffle 6 and the third baffle 7 are of the same height. The three baffles are of the same height, which can prevent the air flow from making abnormal noises when the air is supplied, avoid uneven air flow distribution, and affect the uniformity of the air outflow of the three boxes of the air conditioner.

[0048] Regarding the size and installation position of the baffle, in the preferred embodiment, referring to Figures 5 to 7, the width of the No. 1 baffle 5 is 70% to 90% of the width of the channel at the installation location, the angle with the water outflow direction is 70° to 75°, and the height is 15 to 20 mm; the width of the No. 2 baffle 6 is 35% to 45% of the width of the channel at the installation location, the angle with the water outflow direction is 105° to 110°, and the height is 15 to 20 mm.

[0049] Specifically, the width of the No. 1 baffle 5 is 83% of the width of the channel at the installation location, the angle with the water outflow direction is 73°, and the height is 15mm; the width of the No. 2 baffle 6 is 40% of the width of the channel at the installation location, the angle with the water outflow direction is 107°, and the height is 15mm.

[0050] The first baffle section, located away from the water tank 2, consists of two baffles arranged in a herringbone shape and one baffle perpendicular to the water channel 4. With the water flow as the axis, the bases of baffles 1, 5, and 6 are symmetrical, while baffle 3, 7, is perpendicular to the water flow and crosses the entire channel, as shown in Figures 3 to 7. Preferably, baffles 1, 6, and 7 are of the same height, specifically 15 to 20 mm. A lower height can impair the blocking effect, while a higher height can affect the flow of air.

[0051] Example 3

[0052] The present embodiment provides a three-box air conditioner structure, comprising: an air conditioner, an evaporator, and a blower 1. The air conditioner is provided with a water tank 2, the bottom of which is provided with a drain pipe 3 for draining water. The water tank 2 has a water flow channel 4 on the side near the blower 1. The end of the water flow channel 4 near the blower 1 is provided with a first baffle 5, a second baffle 6, and a third baffle 7 for preventing water from passing through, as shown in Figures 1 to 4. Baffles 1 and 2 are mounted on the two side walls of the lower shell of the evaporator box, respectively, in a herringbone configuration. Baffle 3 is arranged perpendicular to the water flow channel 4 at the connection between the air conditioner and the blower 1, as shown in Figures 3 and 4.

[0053] Preferably, when the first baffle 5 and the second baffle 6 are installed, their installation roots fixed to the side wall of the shell are on a straight line perpendicular to the water flow channel 6 and symmetrical about the water flow channel 4, as shown in Figures 3 and 4.

[0054] In a preferred embodiment, the three-box air conditioner structure further includes a second baffle portion 8 disposed at the connection between the first channel 41 and the second channel 42 of the water flow channel 4, and the second baffle portion 8 is located on the side of the first baffle 5 away from the blower 1. The connection portion here refers to the connection point between the first channel 41 and the second channel 42 and its vicinity. Specifically, in this application, it refers to the bend of the water flow channel 4 and its surrounding area.

[0055] Preferably, as shown in FIG. 3 to FIG. 4 or FIG. 10 , the second baffle portion 8 includes a first baffle 81 provided on one side of the second channel 42 and a second baffle 82 provided on the other side of the second channel 42 .

[0056] In addition, the second baffle portion 8 also includes a third baffle 83, a fourth baffle 84, and a fifth baffle 85. Specifically, the fourth baffle 84 is disposed on the same side as the first baffle 81, at the connection point between the first channel 41 and the second channel 42. The third baffle 83 and the fifth baffle 85 are disposed on the same side as the second baffle 82, and are disposed on the second channel 42 and the first channel 41, respectively. Of course, the arrangement and location of the baffles are not limited to the above and can be adapted to suit, such as being arranged in a staggered manner.

[0057] When the five baffles of the second baffle portion 8 are installed, their angles can be appropriately tilted or perpendicular to the water flow channel 4, and the angles between the five baffles and the water flow direction can also be different.

[0058] Preferably, the width of the second baffle portion 8 is set to 50% to 90% of the width of the water channel 4. If the width is too small, the water blocking effect is not obvious, and if the width is too large, it is not conducive to the backflow of overflow water. Specifically, the width of the second baffle portion 8 can be set to 70% and the height can be set to 10 mm.

[0059] The second baffle 8 is a water retaining structure located near the water tank 2. In one embodiment of the present application, it can be composed of five baffles located within the water flow channel 4. Its function is to increase flow resistance and slow the flow of condensate just after it flows out of the water tank 2. These five baffles are 10 mm high and 70% of the width of the water flow channel. They are staggered, as shown in Figures 3-4 or 10. This ensures that overflowing water can flow smoothly back into the water tank 2 while also increasing resistance to outflow from the water tank 2.

[0060] In this preferred embodiment, the water retaining structure is a two-stage water retaining structure. The water retaining plate close to the water storage tank 2 slows down the outflow of water, and the water retaining plate far away from the water storage tank 2 completely prevents water from overflowing.

[0061] The water baffles near are staggered to increase resistance to the greatest extent, and the water baffles far away use a "human" shaped structure to prevent water from passing through. Assuming that the water passes through the "human", there is still a last water baffle No. 3 baffle 7 to completely block the water flow. The "human" shaped structure can increase the resistance to water flowing outward and prevent water from flowing out to the greatest extent. At the same time, it has a smaller backflow resistance, so that the water passing through the "human" can easily flow back to the water storage tank 2.

[0062] Example 4

[0063] The present embodiment provides a three-box air conditioner structure, comprising: an air conditioner, an evaporator, and a blower 1. The air conditioner is provided with a water tank 2, the bottom of which is provided with a drain pipe 3 for draining water. The water tank 2 has a water flow channel 4 on the side near the blower 1. The end of the water flow channel 4 near the blower 1 is provided with a first baffle 5, a second baffle 6, and a third baffle 7 for preventing water from passing through, as shown in Figures 1 to 4. Baffles 1 and 2 are mounted on the two side walls of the lower shell of the evaporator box, respectively, in a herringbone configuration. Baffle 3 is arranged perpendicular to the water flow channel 4 at the connection between the air conditioner and the blower 1, as shown in Figures 3 and 4.

[0064] Preferably, when the first baffle 5 and the second baffle 6 are installed, their installation roots fixed to the side wall of the shell are on a straight line perpendicular to the water flow channel 6 and symmetrical about the water flow channel 4, as shown in Figures 3 and 4.

[0065] During fixed installation, a connecting plate 51 integral with the first baffle 5 is further provided at the connection between the first baffle 5 and the wall. The connecting plate 51 is a triangular plate or a rectangular plate, as shown in Figures 8 and 9. When set as a rectangular plate, the upper corner of the rectangular structure away from the end of the first baffle 5 may cause abnormal noise in the three boxes of the air conditioner, and the effect is not as good as the triangular structure. Therefore, preferably, the connecting plate 51 is set as a triangular plate.

[0066] The triangular connecting plate 51 at the junction of the first baffle 5 and the wall, in a specific embodiment of the present application, has a height of 12 to 20 mm and a vertex angle of 42° to 50°. Preferably, the height of the triangle is 13 mm and the vertex angle is 43°. The triangular connecting plate 51 has a good water-retaining effect. When water rushes towards the first baffle 5, it will flow toward the wall due to the influence of the plate shape, and the water flow will gather at the junction of the first baffle 5 and the wall. Therefore, increasing the area here can improve the water-retaining ability.

[0067] The three-box air conditioner structure of the present embodiment has baffles 5, 6, and 7 installed at the end of the water channel 4 near the blower 1 to prevent water from passing through. Baffles 5 and 6 are mounted on the two side walls of the lower shell of the evaporator box in a herringbone configuration. Baffle 7 is installed perpendicular to the water channel 4 at the connection between the air conditioner and the blower 1. By using this water-retaining structure and providing a specially designed water-blocking plate in the flow path of condensed water, condensed water is blocked within the air conditioner, preventing it from flowing into the blower 1 or out of the three boxes, thereby ensuring the quality of the blower 1 and improving the user experience.

[0068] In addition, a "human" shaped structure is used to block the passage of water. Assuming that the water passes through the "human", there is a third baffle 7 to completely block the water flow. The "human" shaped structure can increase the resistance of water to the outward flow and prevent water from flowing out to the greatest extent. At the same time, it has a small backflow resistance, so that the water passing through the "human" can easily flow back to the water storage tank.

[0069] In the face of the technical problems to be solved by this application, this application has conducted an effective analysis of the existing situation and proved through experiments that the improved structure solves the existing technical problems. The following is a brief introduction to the experimental process of this application:

[0070] ◇Working condition analysis:

[0071] Driving condition analysis: Average slope 4.4%, round trip approximately 40 km, speed (60-80 km / h), emergency braking on downhill section, rapid left turn or U-turn. Specific parameters are shown in Table 1.

[0072] Table 1: Water leakage statistics

[0073] No water leakage summary: When the X-axis deceleration is less than 0.26g and the Y-axis acceleration is less than 0.24g, there will be no water leakage.

[0074] Water leakage summary: When the X-axis deceleration is greater than 0.43g and the Y-axis acceleration is greater than 0.36g, water leakage will occur.

[0075] ◇The cause of water leakage is clear:

[0076] The outside temperature is (22-29)℃, the humidity is (70-80)%, the air conditioner is set to the temperature Lo, external circulation, the blower is at level 1-2, and the water production is 40ml / min-60ml / min.

[0077] During emergency braking and a large left turn, the condensed water flows in the opposite direction along the water channel under the action of inertia and centrifugal force.

[0078] ◇Risk analysis:

[0079] Data level analysis

[0080] The previous analysis concluded that if the X-axis deceleration is less than 0.26g and the Y-axis acceleration is less than 0.24g, there will be no leakage. The specific parameters are shown in Tables 2 and 3.

[0081] Table 2: X-axis deceleration

[0082] Table 3: Y-axis deceleration

[0083] The probability of a deceleration of less than or equal to 0.26g in the X direction is approximately 96%, and the probability of a deceleration greater than 0.26g is approximately 4%.

[0084] The probability of an acceleration less than or equal to 0.24g in the Y direction occurring is approximately 98%, and the probability of an acceleration greater than 0.24g occurring is approximately 2%.

[0085] In summary, the probability of two working conditions occurring simultaneously is approximately 0.08%.

[0086] ◇Goal setting:

[0087] The improvement goal is to reduce the possibility of water leakage from 0.08% to 0.00001%.

[0088] When the deceleration in X direction is ≥ 0.43g and the acceleration in Y direction is ≥ 0.35g, there is no water leakage.

[0089] ◇Actual vehicle test results:

[0090] The improvement plan was verified to be effective in actual vehicle testing, with no water leakage throughout the entire process.
