Description

Technical Field

[0001] The present invention relates to the field of air conditioning, and in particular to an air conditioning water receiving tray and an air conditioner for transportation vehicles. Background Art

[0002] The water tray is an important component of the air conditioner. Currently, the area above the water tray of the car air conditioner is open, and the front and rear water baffles of the water tray do not take into account that when the car accelerates, decelerates, or makes a sharp turn, the condensed water in the water tray accumulates instantly due to inertia, splashes over the water baffle, and is blown out from the air outlet.

[0003] The defects of the current car water tray:

[0004] 1. The front and rear water baffles are at the same height, and the impact of the irregular movement of the car on the water in the water tray is not considered;

[0005] 2. The drain outlet is higher than the bottom of the water tray, and the effect of gravity on the flow rate of water is not fully utilized;

[0006] 3. The drain outlet of the water tray is a cylinder with regular edges, which does not fully utilize the influence of the Coriolis force on the material;

[0007] 4. The current design of setting a water baffle in the middle of the water tray takes up a large part of the space for water movement and increases the risk of splashing.

[0008] For example, the Chinese patent document, CN106679146A, mainly proposes adding several drainage holes on both sides of the water receiving tray, and the inner wall of the water receiving tray is arc-shaped, and the bottom plate of the water receiving tray is inclined from the middle of the water receiving tray to both sides of the drainage holes in the longitudinal direction, so as to force the water to change its direction. This idea can be used as a reference, but it has the following disadvantages:

[0009] 1. In practice, the height of the water baffle designed based on the condition that the condensed water does not fluctuate is generally 40 mm. This arc-shaped structure on the inner wall cannot effectively prevent splashing when the movement state of the condensed water changes suddenly.

[0010] 2. Since the interior space of a car is generally a closed space, according to a large amount of data, it is found that the dehumidification capacity is in the range of 1.5kg / h-2.5kg / h, and as the cooling progresses, the air humidity in the car will decrease. Therefore, there is no need to design multiple drainage holes for the water tray of a vehicle.

[0011] 3. The setting that the center position of the bottom of the longitudinal right water tray is inclined toward both sides of the drainage hole cannot effectively solve the problem of water splashing when the vehicle is bumpy. The reasons are as follows:

[0012] ① It is clear that the reason why condensed water splashes out is that after its kinetic energy offsets its own gravitational potential energy at the height of the water tray, there is still residual energy, so solving this problem must be considered from an energy perspective.

[0013] ② Water cannot accumulate inside the water tray. In the case of accumulation, the mass of water increases and the momentum becomes larger. However, the water tray is tilted in the length direction and will accumulate naturally. The drainage angle of the drainage hole is between 45° and 90° with the flow direction of the water. The inertia of the water movement is not utilized, but the discharge is blocked. This situation will be aggravated when the vehicle turns or goes up and downhill. Summary of the invention

[0014] In view of this, the present invention provides an air conditioning water receiving tray for transportation vehicles, and the present invention solves at least one of the following technical problems:

[0040] Those skilled in the art will appreciate that the drawings are merely schematic diagrams of example embodiments, and the modules or processes in the drawings are not necessarily necessary for implementing the present disclosure, and therefore cannot be used to limit the protection scope of the present disclosure.

[0041] The following is combined with Figure 1-3 The contents of the specific implementation modes of the present invention are described in detail:

[0042] like Figure 1-3 As shown, the air conditioner water receiving tray of the present invention is schematically shown. A multi-layer splash-proof groove is designed on the inner wall surface of the front and rear water retaining plates 4 of the water receiving tray. The splash-proof groove has three layers. The bottom of the splash-proof groove is designed with rounded corners. When the water at the bottom of the water receiving tray moves violently due to the influence of the external environment, the zigzag water retaining groove with the terminal downward can play two roles:

[0043] 1. The groove direction is designed to be obliquely upward along the direction of water movement, which minimizes the effective positive contact area between the solid and the water to prevent splashing.

[0044] 2. The slotting direction is designed to be diagonally upward along the direction of water movement, and water consumes kinetic energy during the movement.

[0045] 3. When water moves to the corners of the sawtooth groove, the rounded corner structure 54 is designed to prevent turbulence of the water flow in an infinitely small space, avoid splashing, and further guide the water flow back to the water receiving tray.

[0046] 4. The multi-layer serrated grooves can effectively control the splashing of condensed water within a certain range.

[0047] like Figure 1-3 As shown, the air conditioning water receiving tray for transportation vehicles of the present invention comprises a bottom plate 2 and a water retaining plate, the bottom plate 2 and the water retaining plate together enclose a water receiving trough 1, and a splash-proof groove is formed on the inner wall of the water retaining plate. The groove direction of the splash-proof groove of the present invention can be opened obliquely upward from the bottom plate 2 to the water retaining plate. The bottom wall of the splash-proof groove of the present invention is formed with a rounded corner structure 54. The water receiving tray is also provided with at least one drain pipe 6.

[0048] The splash-proof groove of the present invention is formed as a multi-layer splash-proof groove. A sharp angle structure 55 is formed between adjacent splash-proof grooves. The sharp angle structure 55 between adjacent splash-proof grooves is formed as a sawtooth structure.

[0049] The water baffle of the present invention comprises a front water baffle 3, a rear water baffle 4, a left water baffle and a right water baffle, which together with a bottom plate 2 form a rectangular water receiving trough 1.

[0050] The front water baffle plate 3 and the rear water baffle plate 4 are arranged along the length direction of the water receiving trough 1, the left water baffle plate and the right water baffle plate are arranged along the width direction of the water receiving trough 1, the splash-proof groove includes a front splash-proof groove and a rear splash-proof groove, a front splash-proof groove is formed on the front water baffle plate 3, and a rear splash-proof groove is formed on the rear water baffle plate 4, and the front splash-proof groove and the rear splash-proof groove are both arranged along the length direction of the water receiving trough 1.

[0051] The air-conditioning water receiving tray for vehicle in the embodiment of the present invention includes a water receiving trough 1 area, a water receiving tray bottom plate 2, a front water baffle 3, a rear water baffle 4, and a water receiving trough 1; optionally, a drain pipe 6 is arranged at both longitudinal ends of the water receiving tray and is placed horizontally. When the vehicle air conditioner is in operation, no matter whether the air conditioner is swayed to the left or to the right, the condensation generated by the evaporator flows into the water receiving tray bottom plate 2 through the cooling fins on the upper part of the water receiving tray bottom plate 2, so that the condensed water can quickly flow from the water receiving tray bottom plate 2 into the drain pipe 6 for discharge, so that it is not easy to leak or blow water from the air outlet when the vehicle is bumpy or turning uphill, etc., which may cause condensed water to accumulate, thereby improving the user experience, reducing the possibility of condensed water accumulating in the water receiving tray and breeding bacteria, and avoiding the problem that the sinking setting alone cannot effectively drain water and the longitudinal slope and the drainage holes arranged perpendicular to the bottom plate 2 have water accumulation and poor drainage.

[0052] The front and rear water baffles 4 in the embodiment of the present invention have a first splash-proof groove 51, a second splash-proof groove 52, and a third splash-proof groove 53. In this way, even under the operating condition of maximum cooling capacity, if the condensed water cannot be discharged effectively and quickly, the first splash-proof groove 51 forms a first layer of splash-proof barrier, and the condensed water needs to consume a part of the kinetic energy to break through the height of the serrated groove in order to splash out of the water receiving tray; the second splash-proof groove 52 forms a second splash-proof barrier, and the third splash-proof groove 53 forms a third splash-proof barrier.

[0053] Specifically, the serrated groove (splash-proof groove) has two special structures. When the condensed water on the bottom plate 2 of the water receiving tray moves violently under abnormal circumstances, the contact area between the splash-proof corner and the water is small, and the resistance encountered by the water during the movement is negligible, and it is not easy to splash back.

[0054] The slotting direction is designed to be obliquely upward along the direction of water movement, and water consumes kinetic energy during the movement.

[0055] When water moves to the corner of the splash tank, the rounded corner structure 54 is designed to prevent turbulence of the water flow in an infinitely small space, avoid splashing, and further guide the water flow back to the water receiving tray.

[0056] The multi-layer splash guard can effectively control the splash of condensed water within a certain range.

[0057] In addition, the present invention provides an air conditioner, which adopts the air conditioning water receiving tray of the present invention.

[0058] Beneficial effects:

[0059] The air-conditioning water receiving pan for transportation vehicles provided by the present invention comprises a bottom plate 2 and a water retaining plate. The bottom plate 2 and the water retaining plate together form a water receiving trough 1, and a splash-proof groove is formed on the inner wall of the water retaining plate. The water receiving pan of the present invention can effectively prevent water from splashing out through multiple groups of splash-proof grooves on the water retaining plate. The present invention can effectively reduce the flow of water and prevent the occurrence of turbulence through the rounded corner structure 54 at the bottom of the splash-proof groove; the sharp corner structure 55 between adjacent splash-proof grooves of the present invention can effectively break up the water flow and consume the energy of water. The bottom of the splash-proof groove of the present invention is provided with a drain pipe 6 to discharge water in time. The present invention can effectively prevent the condensed water of the air conditioner from splashing out of the water receiving pan through the improvement of the above structure, and the effect is remarkable.

[0060] The exemplary embodiments of the present disclosure are specifically shown and described above. It should be understood that the present disclosure is not limited to the detailed structures, configurations or implementations described herein; on the contrary, the present disclosure is intended to cover various modifications and equivalent configurations included in the spirit and scope of the appended claims.
