Description

Technical Field

[0001] The utility model belongs to the technical field of air conditioners, and in particular relates to a water receiving tray structure and an air conditioner. Background Art

[0002] The onboard auxiliary cooling system is the only cooling system before the aircraft takes off. Different from the aircraft environmental control system, the onboard auxiliary cooling system uses conventional fluorine refrigeration solutions such as compressors and heat exchangers. Limited by the aircraft layout, the various parts of the air conditioning system are located in different positions of the aircraft, and a modular assembly solution is adopted to facilitate after-sales. Therefore, the auxiliary cooling air conditioning system consists of a compressor unit, a condensing air duct unit, an evaporation unit, a controller unit, etc., and each unit is connected by a quick connector.

[0003] The evaporation unit is affected by the space of the placement position, and its size is limited. The temperature of the evaporator is low when working. The air intake at the air inlet end will aggravate the generation of condensed water, and the condensed water is easy to frost in a low temperature environment. The frost of condensed water will block the evaporator, affect the circulation of the air in the evaporator, and cause problems in the cooling work of the evaporator. Since the air inlet end of the evaporator needs to circulate air, if a water receiving tray is set below the air inlet end of the evaporator, the air flow will flow from both sides of the water receiving tray, which will affect the air intake at the air inlet end, and then affect the efficiency of the evaporator. Therefore, there is currently no effective collection structure for the condensed water at the air inlet end of the evaporator. The aircraft will tilt at different angles under different flight conditions, and the working conditions of the aircraft are more complicated. In the prior art, the water receiving tray is a groove-shaped structure. When the aircraft has a tilt angle, the evaporator will also tilt with the angle. The water receiving tray cannot effectively collect and process the condensed water at the air inlet end of the evaporator. The condensed water in the water receiving tray or the change in the angle received will overflow, affecting the normal operation of the evaporator and causing damage to the evaporator.

[0004] Since the water collecting pan in the prior art affects the air intake volume at the air inlet end of the evaporator, and there is no effective collection structure for the condensed water at the air inlet end of the evaporator, the condensed water at the air inlet end of the evaporator cannot be processed, affecting the heat exchange efficiency and normal operation of the evaporator and other technical problems, the utility model studies and designs a water collecting pan structure and an air conditioner.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0032] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0033] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0034] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0035] See also Figure 1-9 As shown, according to an embodiment of the utility model, a water receiving tray structure is provided, including: a second shell 2, a guide member 7 is arranged in the second shell 2, the guide member 7 is used to collect condensed water, a first opening 5 is arranged on the top of the second shell 2, an air inlet 11 is arranged on the bottom of the second shell 2, air flows into the second shell 2 through the air inlet 11, and flows out through the first opening 5, and condensed water falls into the second shell 2 from the first opening 5 and can be collected by the guide member 7. In this technical solution, through the first opening 5 and the air inlet 11, when the water receiving tray is installed below the air inlet end of the evaporator, combined with reference to Figure 8As shown, the air flow in the air duct flows through the air inlet 11 and the first opening 5 in sequence and then flows to the air inlet end of the evaporator, thereby ensuring the circulation of air in the evaporator, so that the water receiving tray affects the air flow at the air inlet end of the evaporator, and improves the heat exchange efficiency of the evaporator. When the condensed water at the air inlet end of the evaporator drips downward under the action of its own gravity, the condensed water is collected through the first opening 5 and the guide member 7, thereby achieving the purpose of collecting water, and the condensed water at the air inlet end of the evaporator is collected and processed.

[0036] In some embodiments, the water receiving tray structure further includes a first shell 1, the top of the first shell 1 is provided with an air outlet, the second shell 2 is provided inside the first shell 1, the bottom of the first shell 1 is provided with a vent, the vent is communicated with the air inlet 11, the guide member 7 is provided with a groove, the notch of the groove is opposite to the first opening 5, and the opening width of the groove is greater than the width of the first opening 5, and there is a gap between the guide member 7 and the side wall of the second shell 2. In this technical solution, through the air outlet, the first opening 5 and the air inlet 11, when the water receiving tray is installed below the air inlet end of the evaporator, combined with reference to Figure 8 As shown, the airflow in the air duct flows through the air inlet 11, the gap between the guide member 7 and the side wall of the second shell 2, the first opening 5 and the air outlet in sequence, and then flows to the air inlet end of the evaporator, ensuring the circulation of the evaporator air, so that the water receiving tray affects the airflow at the air inlet end of the evaporator, and improves the heat exchange efficiency of the evaporator. The guide member 7 is provided with a groove, and the notch of the groove is opposite to the first opening 5. When the condensed water at the air inlet end of the evaporator drips downward under the action of its own gravity, it first passes through the air outlet and the first opening 5. Since the opening width of the groove is greater than the width of the first opening 5, the condensed water will all flow into the groove, thereby achieving the effect of collecting water, and collecting and processing the condensed water at the air inlet end of the evaporator. Of course, the air outlet and the vent can also be set on the side wall of the first shell 1. At this time, the corresponding direction of the second shell 2 can be adjusted.

[0037] In the water receiving tray structure of the utility model, in combination with Figure 1 As shown, the first shell 1 and the second shell 2 are rectangular, the top of the first shell 1 is connected to the outside air, that is, the first shell 1 has no top, and the side wall of the first shell 1 is enclosed between the ends facing away from the bottom to form an air outlet, and the length direction of the second shell 2 is the same as the length direction of the first shell 1, and the guide member 7 extends in the second shell 2 along the length direction, that is, the guide member 7 is respectively connected to the two ends of the length direction of the second shell 2, and the groove also extends in the second shell 2 along the length direction. Furthermore, the shape of the groove is trapezoidal, that is, there is an angle between the side wall of the groove and the ground, and the width of the groove opening is greater than the width of the bottom of the groove, so that the condensed water can quickly gather in the bottom of the groove.

[0038] In some embodiments, the guide member 7 is connected to the two ends of the second shell 2, and the groove penetrates the side wall of the second shell 2 connected to the guide member 7, so that the condensed water in the groove flows out of the second shell 2. Figure 5 As shown, the groove runs through the side wall of the second shell 2 connected to the guide member 7. After the condensed water dripping from the first opening 5 is collected by the groove, the condensed water flows into the first shell 1 through the two end outer walls of the second shell 2, so that the second shell 2 completes the ventilation and condensed water collection functions.

[0039] In some embodiments, a second opening is provided on one side of the second shell 2, and the second opening passes through both ends of the second shell 2 along the length direction of the second shell 2. A second side wall 8 is provided on the side of the second opening close to the bottom of the first shell 1, and one end of the second side wall 8 is connected to the second shell 2, and the other end extends toward the inside of the second shell 2, and the other end of the second side wall 8 extends toward the first opening 5, and the second side wall 8 is located below the guide member 7. In this technical solution, in combination with reference to Figure 5 As shown, when the water receiving tray is tilted and condensed water drips from the first opening, part of the condensed water will fall through the gap between the guide member 7 and the second shell 2. Therefore, a second side wall 8 is provided on the side of the second opening close to the bottom of the first shell 1, one end of the second side wall 8 is connected to the second shell 2, and the other end extends toward the inside of the second shell 2, and the other end of the second side wall 8 extends toward the first opening 5, and the second side wall 8 is located below the guide member 7. When the condensed water falls through the gap between the guide member 7 and the second shell 2, it will fall on the second side wall 8. Under the action of the second side wall 8, the condensed water flows into the first shell 1, thereby ensuring that the condensed water will not fall into the air duct and cause damage to the air duct. Specifically, the second side wall 8 extends obliquely upward, and there is a gap between the second side wall 8 and the bottom of the guide member 7. The second side wall 8 is at least partially located directly below the guide member 7, thereby ensuring that the condensed water falls through the gap between the guide member 7 and the second shell 2 and all falls on the second side wall 8.

[0040] In some embodiments, a third opening is provided on the other side of the second shell 2, and the third opening passes through both ends of the second shell 2 along the length direction of the second shell 2. A third side wall 10 is provided on one side of the third opening close to the bottom of the first shell 1, and one end of the third side wall 10 is connected to the second shell 2, and the other end extends toward the inside of the second shell 2, and the other end of the third side wall 10 extends toward the first opening 5, and the third side wall 10 is located below the guide member 7. In this technical solution, in combination with reference to Figure 5As shown, when the water receiving tray is tilted and condensed water drips from the first opening, part of the condensed water will fall through the gap between the guide member 7 and the second shell 2. Therefore, a third side wall 10 is provided on the side of the second opening close to the bottom of the first shell 1. One end of the third side wall 10 is connected to the second shell 2, and the other end extends toward the inside of the second shell 2. Moreover, the other end of the third side wall 10 extends toward the first opening 5. The third side wall 10 is located below the guide member 7. When condensed water falls through the gap between the guide member 7 and the second shell 2, it will fall on the third side wall 10. Under the action of the third side wall 10, the condensed water flows into the first shell 1, thereby ensuring that the condensed water will not fall into the air duct and cause damage to the air duct. Specifically, the third side wall 10 extends obliquely upward, and there is a gap between the third side wall 10 and the bottom of the guide member 7. The third side wall 10 is at least partially located directly below the guide member 7, thereby ensuring that the condensed water will fall through the gap between the guide member 7 and the second shell 2 and all fall on the third side wall 10. Under the joint action of the third side wall 10 and the second side wall 8 , the condensed water on both sides of the guide member is discharged into the first shell 1 through the third side wall 10 and the second side wall 8 respectively.

[0041] In some embodiments, the first side wall 6 is provided at one end of the two side walls of the second shell 2 facing away from the air inlet 11, and the first side wall 6 extends toward the inside of the second shell 2, and the first side wall 6 extends toward the outside of the first shell 1, and the first side wall 6 is located inside the first shell 1, and a first opening 5 is formed between the two first side walls 6. In this technical solution, in combination with reference to Figure 5 As shown, when condensed water drips vertically through the first side wall 6, the first side wall 6 also has a diversion effect. The first side wall 6 is inclined upward, and part of the condensed water will directly flow into the first shell 1 under the action of the first side wall 6, thereby improving the collection efficiency of the condensed water in the water receiving tray.

[0042] The water receiving tray structure of the utility model has the advantages of small placement area, strong water receiving capacity, good ventilation effect and adaptability to multi-angle tilting placement. It can guide the condensed water of the evaporator in a small space to avoid quality problems such as water accumulation, water leakage and frosting caused by condensed water. Take the rectangular evaporation unit as an example.

[0043] The water receiving tray structure of the utility model realizes the functions of small placement area, strong water receiving capacity, good ventilation effect and adaptability to multi-angle tilted placement by means of staggered multi-layer placement and side water guide. Compare the cross-sectional area of ​​the air inlet 11 of the water receiving tray with the cross-sectional area of ​​the air outlet, and take the minimum value as X. The ventilation capacity of the water receiving tray is related to the minimum area X of the inlet and outlet ends. The larger the X value, the stronger the ventilation capacity. Under the condition of meeting the working conditions, its ventilation capacity should be increased as much as possible. Therefore, the water receiving tray structure of the utility model is designed in a staggered multi-layer placement manner. In order for the water receiving tray to adapt to the working conditions of multi-angle tilted placement, the water receiving tray is designed by side water guide.

[0044] The water receiving tray structure of the utility model discharges condensed water to the first guide channels 9 on both sides through multiple offset placements. In order to adapt to complex working conditions with multiple angles of inclination, the drainage plate is folded and water-guiding sides are designed around the water receiving tray so that the drainage device can be used under flight conditions.

[0045] In some embodiments, a third shell 4 is further disposed in the first shell 1, and the structure of the third shell 4 is the same as that of the second shell 2, and the structure of the third shell 4 is symmetrical to that of the second shell 2. Figure 5 As shown, the structure of the third shell 4 is the same as that of the second shell 2, and the structure of the third shell 4 is symmetrical to that of the second shell 2. Furthermore, the structure of the third shell 4 is mirror-symmetrical to that of the second shell 2 along one side wall of the second shell 2, and the third shell 4 is connected to two opposite side walls of the second shell 2, then the two adjacent second side walls 8 form a V-shaped structure, and the V-shaped structure can collect the condensed water of the third shell 4 and the second shell 2 at the same time, and discharge it from the ends of the third shell 4 and the second shell 2. The two adjacent first side walls 6 also form a V-shaped structure, so that the condensed water between the third shell 4 and the second shell 2 is collected, and the condensed water flow path mode within the V-shaped structure composed of the two adjacent first side walls 6 and the V-shaped structure composed of the two adjacent second side walls 8 is the same as the flow mode of the condensed water on the guide member 7, and both are discharged through the ends of the third shell 4 and the second shell 2.

[0046] In some embodiments, the air inlet 11 is at least partially connected to the third shell 4, and the remaining part is connected to the second shell 2. After the airflow flows in from the air inlet 11, it flows through the gap between the guide member 7 and the side wall of the second shell 2, the first opening 5 and the air outlet in sequence, and then flows out of the first shell 1. In this technical solution, the air inlet 11 is at least partially connected to the third shell 4, and the remaining part is connected to the second shell 2. Preferably, along the width direction of the air inlet, the second shell 2 and the third shell 4 are each covered with half of the width of the air inlet, that is, the airflow flowing into the air inlet 11 flows evenly into the second shell 2 and the third shell 4, and through the second shell 2 and the third shell 4, the airflow circulation area is increased, and the heat exchange efficiency of the evaporator is guaranteed.

[0047] In some embodiments, a temperature sensor and an electric heater are provided on the first shell 1, and the temperature sensor is used to detect the real-time temperature of the first shell 1, and the electric heater can adjust the heating temperature according to the real-time temperature detected by the temperature sensor. In this technical solution, when warm air enters the air inlet end of the evaporator, the outer wall of the first shell 1 is affected by condensed water and the temperature becomes lower, and the air entering the water receiving tray is ambient air. When the ambient air temperature is high, condensed water is easily generated on the outer wall of the first shell 1. If the condensed water is not discharged by guidance, it is easy to cause quality problems such as water accumulation and leakage. For this reason, a temperature sensor and an electric heater are installed on the outer wall of the first shell 1, and a preset program adjusts the power of the electric heater by detecting the actual temperature through the temperature sensor, and then adjusts the temperature of the outer wall of the water receiving tray. This makes the temperature difference between the outer wall of the water receiving tray and the ambient air smaller, avoiding the generation of condensed water on the outer wall.

[0048] In some embodiments, a first guide channel 9 is formed between the side wall of the second shell 2 and the side wall of the first shell 1, a second guide channel 12 is formed between the end of the second shell 2 and the end of the first shell 1, the first guide channel 9 is connected to the second guide channel 12, and a drain pipe 3 is provided on the first shell 1, and the condensed water in the second guide channel 12 can be discharged through the drain pipe 3. In this technical solution, in combination with reference to Figures 2 to 4 , Figure 8As shown, the length, width and height of the second shell 2 are all smaller than those of the first shell 1. Specifically, the length and width of the first shell 1 are greater than twice the length and width of the second shell 2, so that a first guide channel 9 and a second guide channel 12 are formed between the second shell 2 and the first shell 1. When the condensed water on the second shell 2 flows out, it flows out from the drain pipe 3 through the first guide channel 9 and the second guide channel 12. Preferably, the drain pipe 3 is arranged on the side wall of the first shell 1 near the bottom of the first shell 1. The drain pipe 3 can be arranged on each side wall of the first shell 1. When the water receiving tray is tilted, it is convenient for the condensed water to be discharged from the first shell 1. Preferably, along the length direction of the first shell 1, the bottom of the first shell 1 can be arranged as an inclined surface, so as to facilitate the discharge of the condensed water.

[0049] See also Figure 6 As shown in the figure, when the condensed water drops vertically, the dripping direction of the condensed water is as shown in the figure below. Figure 6 As shown in the figure, the condensed water drips vertically. When the condensed water drips vertically downward, the first side wall 6 and the guide member 7 guide the condensed water in the front-back direction to the second guide channel 12. When the condensed water drips vertically downward, the third side wall 10 close to the first guide channel 9 guides the condensed water to drip toward the first guide channel 9, and then follows the guidance of the water guide groove to discharge the condensed water from the water tray drain pipe 1 to the inside of the water tray.

[0050] See also Figure 7 As shown, when the water tray is tilted due to working conditions, for example, tilted 30° counterclockwise, part of the condensed water drips to the second side wall 8 and the inside of the second shell 2 due to the tilted angle. The condensed water is drained from the second side wall 8 to the second guide channel 12, and the third side wall 10 to the first guide channel 9. The other condensed water is diverted to the guide groove in a similar direction to the vertical dripping mentioned above, and then discharged from the inside of the water tray through the water tray drain pipe 1.

The above is only a preferred implementation of the utility model.
