The present invention provides a water collecting structure for an integrated air conditioner, please refer to fig. 1 to 3, 5 and 6, which comprises a water pumping structure (please refer to an axial flow wind wheel 232 and/or a water pumping ring 24 in fig. 3), and a first heat exchanger 21 and a second heat exchanger 22 which are connected with each other; wherein the thin dotted line in fig. 1 indicates the flow direction of a part of the air flow in the unitary air conditioner. Referring to fig. 4 and 7 to 9, in an embodiment of the invention, the water collecting structure includes:

The water receiving tray 311 is used for receiving the condensed water of the second heat exchanger 22, and the water receiving tray 311 is provided with a water outlet 31a; and

the water collecting disc 12 is provided with a water diversion groove 121 and a water collecting groove 122, one end of the water diversion groove 121 is communicated with the water outlet 31a, and the other end of the water diversion groove 121 is communicated with the water collecting groove 122; the sump 122 is configured to allow at least a portion of the tapping structure to protrude into to tap water within the sump 122 to the first heat exchanger 21.

It should be noted that, the integral air conditioner in the embodiment of the present invention refers to a movable integral air conditioner that is suitable for use in home and office situations, or an integral air conditioner that is installed in a mobile house or a container house, or an integral air conditioner that is installed in a motor home, and it should be understood that the present invention is not limited to specific applications of the integral air conditioner. For convenience of understanding, an integrated air conditioner mounted on a car as a house will be described hereinafter as an example.

Without loss of generality, the integrated air conditioner of the caravan is generally installed on the upper side of a roof cover of the caravan, and the roof cover is provided with a ventilation air inlet hole and a ventilation air outlet hole. Referring to fig. 1, 2, 6 and 9, in an embodiment of the present invention, optionally, the integrated air conditioner includes a housing 10, an indoor air duct 30 and a second fan 25, the housing 10 includes a water collecting tray 12 and a top cover 11 covering the water collecting tray 12, the housing 10 is provided with an indoor air inlet 10a and an indoor air outlet 10b, one end of the indoor air duct 30 is connected with the indoor air inlet 10a, and the other end is connected with the indoor air outlet 10 b; the second fan 25 and the second heat exchanger 22 are both disposed in the indoor air duct 30, the second fan 25 is configured to drive air from the indoor air inlet 10a to the indoor air outlet 10b, the indoor air inlet 10a is communicated with the ventilation air outlet, and the indoor air outlet 10b is communicated with the ventilation air inlet. Thus, the air in the motor home enters the indoor air duct 30 of the integral air conditioner through the ventilation air outlet and the indoor air inlet 10a, exchanges heat with the second heat exchanger 22 in the indoor air duct 30, and returns to the interior of the motor home through the indoor air outlet 10b and the ventilation air inlet, thereby realizing the function of adjusting the temperature in the motor home.

Referring to fig. 1 to 3, in an embodiment of the present invention, optionally, the casing 10 is further provided with an outdoor air inlet 10d and an outdoor air inlet 10c, an outdoor air flow channel 10e is formed between the outdoor air inlet 10c and the outdoor air outlet 10d, the integrated air conditioner further includes a first fan 23 disposed in the outdoor air flow channel 10e, the first fan 23 is used for driving air to flow from the outdoor air inlet 10c to the outdoor air outlet 10d, and the first heat exchanger 21 is disposed in the outdoor air flow channel 10 e. The integral air conditioner is mainly used for realizing cooling adjustment of the temperature in the vehicle without losing generality, namely, the integral air conditioner is in a refrigerating mode. When the unitary air conditioner is in the cooling mode, the first fan 23 is continuously operated to ensure that the air energy outside the unitary air conditioner continuously flows through the outdoor air flow passage 10e, and performs efficient heat exchange with the first heat exchanger 21 to timely take away the heat of the first heat exchanger 21. When the air in the vehicle flows into the indoor air duct 30 and exchanges heat with the second heat exchanger 22, part of the air is condensed to form water drops, and then drops or flows into the water receiving tray 311 under the action of gravity. When the condensed water in the water receiving tray 311 is formed to a certain scale, it naturally flows to the drain port 31a, flows into the water guide groove 121 of the water collecting tray 12 through the drain port 31a, and then flows into the water collecting groove 122, that is, when the integrated air conditioner is installed at the top of the caravan, the bottom of the water collecting groove 122 is at the lowest or nearly lowest position, so that the condensed water flows to and is concentrated in the water collecting groove 122 by gravity, thereby guaranteeing the water level in the water collecting groove 122. On the basis, the water taking structure of the integral air conditioner can throw condensed water gathered in the water collecting tank 122 to the periphery, and part of condensed water splashes on the first heat exchanger 21 so as to take away heat on the first heat exchanger 21 by utilizing the condensed water, thereby improving the heat dissipation efficiency of the first heat exchanger 21.

In an embodiment, the second fan 25 includes a second driving member and a cross-flow wind wheel drivingly connected to the second driving member, and an axis of the cross-flow wind wheel is disposed intersecting with a distribution direction of the indoor air inlet 10a and the indoor air outlet 10 b. In particular, the second drive member may be one of a drive motor, a hydraulic motor or a pneumatic motor. Therefore, the second fan 25 has smaller volume, which is beneficial to the miniaturization design of the integral air conditioner, and the cross flow wind wheel can blow the air flow to a more indoor area, and the air outlet is softer, thereby improving the user experience.

As will be readily appreciated, if the unitary air conditioner is in the heating mode, i.e., the second heat exchanger 22 heats the air in the car as it is, the first heat exchanger 21 has no heat dissipation requirement, so even if no condensed water is generated on the second heat exchanger 22, the overall heat exchange efficiency of the unitary air conditioner is not affected. For ease of understanding, the description will be given below taking an example in which the unitary air conditioner is in the cooling mode.

In the technical scheme of the invention, the condensed water generated on the second heat exchanger 22 is collected through the water collecting tank 122 on the water collecting tray 12, and the condensed water collected in the water collecting tank 122 is thrown to the first heat exchanger 21 by utilizing the water beating structure, so that the condensed water is fully utilized to assist the first heat exchanger 21 to radiate heat, thereby improving the radiating efficiency of the first heat exchanger 21 and further improving the heat exchanging efficiency of the whole machine of the integral air conditioner.

It should be noted that, the water receiving tray 311 and the water collecting tray 12 may be separately disposed, for example, referring to fig. 6 and 8, in an embodiment, the water receiving tray 311 and the indoor air duct 30 are integrally formed, the indoor air duct 30 is installed on the water collecting tray 12, the water outlet 31a is disposed at a bottom wall of the water receiving tray 311, and the water trough 121 is disposed at a lower side of the water outlet 31 a. Specifically, the indoor air duct 30 includes an inner air duct support 31 and an inner air duct cover 32 covering the inner air duct support 31, the water pan 311 and the inner air duct support 31 are integrally formed and disposed between the indoor air inlet 10a and the outdoor air inlet 10c, and the second heat exchanger 22 is disposed on the upper side of the water pan 311. Of course, in other embodiments, the water receiving tray 311 and the water collecting tray 12 may be integrally formed and configured as a chassis of the unitary air conditioner.

As can be appreciated, on the one hand, in order to reduce the windage of the vehicle and achieve the light weight of the vehicle, the trend in designing the air conditioner for the motor home is necessarily toward miniaturization, and therefore, the layout space inside the air conditioner for the motor home is very limited, which results in significant limitation of design parameters such as the shape and size of the parts such as the first fan 23 and the first heat exchanger 21, and the power. On the other hand, the space in the motor home is large and the internal structure is complex, so the demand on the refrigerating capacity is large, and if the heat dissipation of the first heat exchanger 21 is realized by only relying on the first fan 23, the whole heat exchange efficiency of the integral air conditioner is lower, so that the integral air conditioner cannot well meet the refrigerating demand of a user. The integral air conditioner provided by the embodiment of the invention can fully utilize the collected condensed water to assist the first heat exchanger 21 to dissipate heat on the premise of not remarkably increasing the size of the integral air conditioner or even not increasing the size, and remarkably improves the heat exchange efficiency of the whole air conditioner, thereby meeting the miniaturization design requirement of the motor home air conditioner and well meeting the refrigeration requirement of users.

Specifically, the water-beating structure has various structural forms, for example, referring to fig. 3, 4 and 6, in an embodiment, the first fan 23 includes a first driving member 231 and a wind wheel connected to the first driving member 231, and the water-beating structure includes the wind wheel of the first fan 23. Specifically, the first driving member 231 may be one of a driving motor, a hydraulic motor, or a pneumatic motor, and the wind wheel may be one of an axial flow wind wheel, a cross flow wind wheel, a centrifugal wind wheel, or the like. In this embodiment, optionally, the wind wheel is configured as an axial flow wind wheel 232, and the free ends of the blades on the axial flow wind wheel 232 (i.e. the ends far away from the axis) can invade the condensed water in the water collecting tank 122 when rotating to the lowest point, so that the condensed water is continuously carried along and thrown around in the continuous rotation, so that part of the thrown condensed water is directly splashed onto the first condenser, and the part of the thrown condensed water is blown towards the first condenser by the airflow, thereby achieving the purpose of assisting the heat dissipation of the first condenser. Of course, in other embodiments, the wind wheel may also be configured as a centrifugal wind wheel or a cross-flow wind wheel, as long as the blades of the wind wheel are capable of beating and splashing the condensed water in the water collection tank 122 towards the first condenser.

Referring to fig. 3, 4 and 6, in this embodiment, the water pumping structure further includes a water pumping ring 24, and the water pumping ring 24 is connected to the free ends of the blades of the axial flow wind wheel 232 and is disposed near the first heat exchanger 21. In this way, the water-beating ring 24 rotates along with the rotation of the wind wheel, so that condensed water in the water-collecting tank 122 is beaten and flown up, and the airflow kinetic energy in the outdoor airflow channel 10e is fully utilized, so that more condensed water can fly to the first heat exchanger 21, and the heat dissipation efficiency of the first heat exchanger 21 is further improved. It should be noted that, the water-beating ring 24 refers to a structure in which the water-beating structure is in a closed ring shape or a substantially ring shape, that is, the water-beating structure does not have to be in a closed ring shape, but may be a plurality of arc-shaped brackets connected to the free ends of the blades, and the plurality of arc-shaped brackets are distributed at intervals along the axial direction of the wind wheel and form a substantially ring-shaped structure. It should be noted that the water pumping structure is at least partially located in the water collecting tank 122, which means that a point on the outer edge of the water pumping structure farthest from the axis may invade into the water collecting tank 122 during rotation, thereby striking condensed water in the water collecting tank 122. In this way, the blades on the first fan 23 and the water-beating ring 24 will both lift the condensed water in the water-collecting tank 122 during the rotation process, so as to further improve the auxiliary heat exchange effect of the condensed water on the first heat exchanger 21. Of course, in other embodiments, the water play structure may include only the water play ring 24, or only the wind wheel.

Referring to fig. 3 and 4, in order to ensure that the water ring 24 can maintain the smoothness and reliability of operation for a long period of time, in one embodiment, the distance between the outer edge of the water ring 24 and the bottom surface of the water collection tank 122 is set to be e, and e is 7 mm.ltoreq.10 mm. For example, e may take the value 7.5mm, 8mm, 9mm, etc. The bottom surface of the water collection tank 122 is the bottom surface of the tank located directly below the water delivery structure, and e is the distance between the lowest point of the portion of the water delivery ring 24 that penetrates into the water collection tank 122 and the bottom surface of the tank. It will be appreciated that if e is too small, it may be possible to cause the water ring 24 to interfere with the bottom wall of the water collecting tank 122 under the influence of the manufacturing tolerance and the assembly tolerance of the parts, thereby affecting the normal operation of the water ring 24 and the first fan 23. Second, e cannot be excessively small in consideration of the fact that foreign materials such as silt may be deposited in the sump 122 after the long-term use of the unitary air conditioner, resulting in the interference of the movement of the water ring 24 with the foreign materials and the inability to operate normally. If the value of e is too large, the diameter of the corresponding wind wheel is obviously reduced, so that the heat dissipation effect of the first fan 23 on the first heat exchanger 21 is reduced.

Referring to FIGS. 3 and 4, in one embodiment, the distance between the outer edge of the water ring 24 and the top surface of the side wall of the water collection tank 122 is set to be E, and E.ltoreq.1.5E.ltoreq.3e. For example, E may take the value of 11mm, 15mm, 20mm, 25mm, or the like. It should be noted that the top surface of the side wall of the tank refers to a top surface nearest to the bottom surface of the tank, that is, the top surface corresponds to the maximum height of the water stored in the water collecting tank 122; e denotes the distance between the lowest point of the portion of the water ring 24 that intrudes into the water collection sump 122 and the top surface of the sump sidewall, i.e., E denotes the intrusion depth of the water ring 24 into the water collection sump 122. It can be appreciated that if the value of E is too small, the water amount that the water ring 24 can hit is limited, resulting in insufficient water-beating effect; if E is too large, this means that the height of the side wall of the water collecting tank 122 is high, which has the adverse effect of reducing the cross-sectional area of the outdoor airflow passage 10E, that is, reducing the ventilation air volume in the outdoor airflow passage 10E. According to the technical scheme, the E is more than or equal to 7mm and less than or equal to 10mm, and the E is more than or equal to 1.5E and less than or equal to 3E, so that the heat exchange efficiency of the whole machine is comprehensively improved by obtaining excellent water pumping effect to assist the heat dissipation of the first heat exchanger 21 while obtaining larger outdoor ventilation air quantity.

Referring to fig. 3, 4 and 9, in order to further enhance the auxiliary effect of the condensed water on the heat dissipation of the first heat exchanger 21, in an embodiment, the water collecting tank 122 includes a first tank section 1221 and a second tank section 1222 distributed along the first direction, the first tank section 1221 is in communication with the water diversion tank 121, the bottom surface of the first tank section 1221 is lower than the bottom surface of the second tank section 1222, the water diversion structure is located in the first tank section 1221, and the first heat exchanger 21 is located in the second tank section 1222. Thus, under the premise that the water beating structure can beat sufficient water quantity, the bottom end of the first heat exchanger 21 is immersed in the condensed water in the second groove section 1222, so that the auxiliary heat dissipation effect of the condensed water is further improved. The height of the integral air conditioner is the height difference of each part on the integral air conditioner relative to the horizon by taking the horizon as a reference after the integral air conditioner is correctly installed at the top of a motor home in a state that the integral air conditioner is correctly installed in place for use. It is easy to understand that in the present embodiment, the distance between the outer edge of the water ring 24 and the bottom surface of the first groove section 1221 is the distance e between the outer edge of the water ring 24 and the bottom surface of the water collection groove 122. Of course, in other embodiments, it is also possible that the water collection tank 122 is provided with only the first tank section 1221, and that the water intake structure and the first heat exchanger 21 are both located within the first tank section 1221; alternatively, the tapping structure is located in the first tank section 1221 and the first heat exchanger 21 is located outside the water collection tank 122.

Referring to fig. 3, 4 and 9, in an embodiment, the outdoor air outlet 10d is disposed at a side of the housing 10, the tank sidewall of the water collecting tank 122 includes a first wall section 122a and a second wall section 122b, the first wall section 122a is disposed near the outdoor air outlet 10d, the second wall section 122b is connected with the tank sidewall of the water diversion tank 121, and the first wall section 122a and the lower side edge of the outdoor air outlet 10d are configured as the same structure. Specifically, in the present embodiment, the top cover 11 of the casing 10 is spliced with the first wall section 122a and the outdoor air outlet 10d is formed at the splice, so that the first wall section 122a is directly used as the lower side edge of the outdoor air outlet 10d, the structure of the casing 10 can be simplified, and the manufacturing cost of the integral air conditioner can be reduced. Also, in the embodiment in which the first heat exchanger 21 is located in the second groove section 1222, the first heat exchanger 21 can be also arranged in a region closer to the outdoor outlet 10d, thereby facilitating more compact arrangement of the internal parts of the unitary air conditioner in the first direction. Of course, in other embodiments, the side edge of the water collecting tray 12 may be turned upward to form a reinforcing flange, and the reinforcing flange and the lower side edge of the outdoor air outlet 10d may be configured to be the same, and the first wall section 122a may be spaced from the reinforcing flange along the first direction.

In one embodiment, the height of the first wall section 122a is less than the height of the second wall section 122 b. That is, the first wall section 122a is shorter than the second wall section 122b, and when the water level in the water collection sump 122 is high, water overflows preferentially through the first wall section 122a and flows to the outside of the unitary air conditioner, thereby avoiding the problem of water accumulation in the area of the water collection tray 12 other than the water collection sump 122. Of course, in other embodiments, it is also possible that the top surface height of the first wall section 122a is greater than or equal to the top surface height of the second wall section 122 b.

Referring to fig. 9, in an embodiment, the side wall of the water diversion trench 121 includes a third wall section 121a and a fourth wall section 121b, the third wall section 121a is disposed near the indoor air inlet 10a, the fourth wall section 121b is connected with the second wall section 122b, the height of the third wall section 121a is greater than the height of the fourth wall section 121b, and the height of the fourth wall section 121b is greater than or equal to the height of the second wall section 122 b. That is, the third wall segment 121a is higher than the fourth wall segment 121b, the first wall segment 122a and the second wall segment 122b, so that even if the water level in the water collecting tank 122 and the water guiding tank 121 is high to cause water in the water collecting tank to overflow, the water overflows to the outside of the tank preferentially from other positions rather than the third wall segment 121a, thereby reducing the risk of condensed water flowing into the indoor space of the caravan through the indoor air inlet 10 a. Of course, in other embodiments, the heights of the third wall section 121a, the fourth wall section 121b, and the second wall section 122b may also be arranged in a flat manner.

Referring to fig. 6 and 8, in one embodiment, the height difference between the bottom surface of the water tray 311 and the top surface of the first wall section 122a is set to d, where d is greater than 0 and less than or equal to 6mm. For example, d may take the value of 3mm, 4mm, 5mm, or the like. That is, the bottom surface of the water receiving tray 311 is higher than the top surface of the first wall section 122a, so that the condensed water in the water receiving tray 311 can be smoothly discharged from the water outlet 31a to the water guide groove 121 in time and then flows back into the water receiving tray 122 in time, and even if the water level in the water receiving tray 122 is too high to cause overflow of the condensed water, for example, when the condensed water overflows to the outside of the shell 10 from the first wall section 122a, the water in the water receiving tray 122 and the water guide groove 121 can not flow back into the water receiving tray 311, thereby avoiding the problem that the water level in the water receiving tray 311 is too high to overflow everywhere. It can be appreciated that, under the condition that the height dimension of the inner portion of the housing 10 is the same, if the bottom surface of the water receiving tray 311 is too high, the structure of the water receiving tray 311 occupies the height space, which results in the reduction of the height dimension of the second condenser, thereby being unfavorable for the heat exchange efficiency of the second condenser.

Referring to fig. 6 and 7, in an embodiment, the water tray 311 has a water blocking rib 312 near the indoor air inlet 10a, and the height difference between the top surface of the water blocking rib 312 and the bottom surface of the water tray 311 is set to be D, where D is equal to or greater than 2D and equal to or less than 6D. For example, D may take the value of 6mm, 8mm, 10mm, 15mm, 20mm, 30mm, or the like. Thus, if the drain of the water receiving tray 311 is not smooth, so that excessive condensed water stored in the water receiving tray 311 is caused, even if the integral air conditioner is driven to shake more severely in the running process of the caravan, the condensed water which is sloshed in the water receiving tray 311 cannot cross the water retaining rib 312 and flow into the indoor air inlet 10a, and falls into the indoor space of the caravan from the indoor air inlet 10a downwards. As can be easily understood, since the water blocking rib 312 is located between the indoor air inlet 10a and the second heat exchanger 22, that is, the air flow flowing from the indoor air inlet 10a to the second heat exchanger 22 is disturbed by the water blocking rib 312, if the height of the water blocking rib 312 is too high, the air inlet of the indoor air inlet 10a is significantly blocked, which is further unfavorable for the heat exchange effect of the second heat exchanger 22.

Referring to fig. 9, in order to further reduce the risk of condensed water flowing into the indoor air inlet 10a, in an embodiment, a water blocking flange 123 is protruding from an inner edge of the indoor air inlet 10a, and a groove sidewall of the water diversion groove 121 is located on a side of the water blocking flange 123 away from the indoor air inlet 10a and is spaced from the water blocking flange 123. That is, the water blocking flange 123 is additionally provided around the indoor air inlet 10a as a water-proof line, and even if a small amount of condensed water overflows from the third wall section 121a to the outside of the tank, the condensed water is blocked by the water blocking flange 123, thereby preventing the condensed water from entering the indoor air inlet 10a.

Referring to fig. 7 and 9, in order to solve the problem that condensed water overflows to the outside of the tank and accumulates in the area of the water collecting tray 12 located at the outside of the tank, in one embodiment, a plurality of drainage through holes 124 are further formed at intervals at the bottom of the water collecting tray 12, and at least one drainage through hole 124 is located at the outside of the tank of the water collecting tray 122. Specifically, the aperture of the drain through hole 124 is 20mm or more. Without loss of generality, the integral air conditioner at the top of a motor home is usually provided with a gap with the roof, i.e. the bottom of the casing 10 of the integral air conditioner is only connected and fixed with the edges of the ventilation inlet holes and the ventilation outlet holes of the roof, while other areas of the bottom of the casing 10 are provided with gaps with the roof. In this way, by directly opening the drain through holes 124 in the bottom of the water collecting tray 12, condensate that accidentally overflows the water collecting tank 122 or the water guide tank 121 can flow to the outside of the housing 10 via these drain through holes 124 and be discharged via the gap between the housing 10 and the roof. It should be noted that, if rainwater accidentally enters the housing 10 through the outdoor air inlet 10c, etc., and accumulates in the area of the water collecting tray 12 outside the tank, it can be drained away in time through the drainage through holes 124. In the present embodiment, optionally, at least one drainage through hole 124 is located outside the groove of the water diversion groove 121. In this way, the drain through holes 124 are provided on the outer sides of the water guide grooves 121 and the water collecting grooves 122, so that excessive condensed water or rainwater accidentally entering the casing 10 can be drained away more quickly. It should be noted that the drainage through hole 124 may also be a part of the outdoor air intake 10c, that is, air enters the outdoor air flow channel 10e through the drainage through hole 124. Of course, in other embodiments, the drain through hole 124 may be provided only on the outside of the sump 122, or the drain through hole 124 may be provided only on the outside of the sump 121.

Referring to fig. 3 and 9, in an embodiment, a bottom surface of the water collecting tank 122 is convexly provided with a squeezing structure 125, and the squeezing structure 125 is used to reduce a water storage volume of the water collecting tank 122. In this way, the water storage volume of the water collecting tank 122 can be reduced through the squeezing structure 125, so that condensed water can be more concentrated in the water collecting tank 122, and the water surface height is raised under the condition of the same volume of condensed water, thereby being beneficial to ensuring the water level height required by the water pumping structure during the water pumping action. Without loss of generality, when the unitary air conditioner is used for refrigerating the indoor space of the motor home, the second heat exchanger 22 is limited in dehumidifying amount and the generated condensed water is limited because the indoor space is well sealed and the space volume is smaller than that of a house. In this embodiment, the squeeze structure 125 is provided to raise the water level of a small amount of condensed water, so that the water pumping structure can pump water and continuously operate, and the integral air conditioner is more suitable for being applied to a motor home. Specifically, the standoff structure 125 may be configured as a boss or annular bead. It should be noted that when the squeeze structure 125 is configured as a boss, the top surface of the boss can also be used as a supporting surface for other parts, for example, the bottom of the first fan 23 is supported on the boss.

In one embodiment, the plurality of squeeze structures 125 are provided, and the plurality of squeeze structures 125 are integrally formed with the water collection tray 12. In this way, the structure of the unitary air conditioner can be simplified and the manufacturing cost thereof can be reduced. Of course, in other embodiments, the squeeze structure 125 may be assembled separately from the water collecting tray 12, that is, the squeeze structure 125 and the water collecting tray 12 are two separate parts and then assembled together, for example, the squeeze structure 125 is configured as a part that is not easy to absorb water, such as a rubber cushion, and the rubber cushion is adhered to the bottom surface of the water collecting tray 12.

Referring to fig. 4 and 8, in order to improve the collection efficiency of condensed water, in one embodiment, the water guide groove 121 extends obliquely downward in a direction approaching the water collection groove 122. In this way, the condensed water flowing into the water guide groove 121 from the drain port 31a of the water receiving tray 311 naturally flows downward under the action of gravity until the inside of the water collecting groove 122, thereby improving the collection efficiency and effect of the condensed water by the water collecting groove 122. Specifically, in this embodiment, the second heat exchanger 22 and the first heat exchanger 21 are optionally arranged in order along the first direction, and the head and the tail of the caravan are arranged in order along the first direction, that is, the first direction refers to a direction extending from front to back, and the water-guiding groove 121 extends obliquely downward along the first direction. In this way, the acceleration during the travel of the caravan can enable the condensed water to flow more rapidly and collect in the water collection tank 122 for use by the water-fetching structure. Of course, in other embodiments, the first direction may be parallel to the left-right direction of the caravan.

Referring to fig. 4, 8 and 9, in one embodiment, the water diversion grooves 121 are at least two, and the at least two water diversion grooves 121 are respectively disposed at two opposite sides of the indoor air outlet 10b in the second direction, where the second direction intersects the first direction. Specifically, in this embodiment, the first direction is disposed perpendicular or nearly perpendicular to the second direction, that is, the first direction extends along the front-rear direction of the caravan, and the second direction extends along the left-right direction of the caravan. In this way, the collection speed of the condensed water can be increased by the plurality of water diversion grooves 121, thereby ensuring that the inside of the water collection groove 122 is kept at a proper water level. In the embodiment of the present invention, a plurality refers to two or more. Of course, in other embodiments, only one water trough 121 may be provided.

Referring to fig. 4, 8 and 9, in one embodiment, one end of at least two water diversion grooves 121 near the water collection groove 122 is communicated and forms a water diversion inclined surface 121c, and the water diversion inclined surface 121c is communicated with the water collection groove 122. That is, the ends of the plurality of water diversion grooves 121 communicate and form one water diversion slope 121c having a large bottom area, and then the ends of the water diversion slope 121c communicate with the water collection groove 122. It will be readily appreciated that if the condensed water flowing in each water guide groove 121 is rare, the flow speed of the small water flow will be slower, and when the water in the water guide grooves 121 is converged into a larger water flow, the flow speed of the large water flow will be significantly improved, so that the condensed water generated on the second heat exchanger 22 is beneficial to flow to and be converged into the water collecting groove 122 in time. In this embodiment, an extrusion structure 125 is optionally also provided on the water diversion slope 121 c. Of course, in other embodiments, each of the water diversion grooves 121 may be in communication with the water collection groove 122, respectively, i.e., the water in each of the water diversion grooves 121 may flow into the water collection groove 122, respectively, and may not be collected together in the water collection groove 122.

The invention also provides an integral air conditioner which comprises the water collecting structure, and the specific structure of the water collecting structure refers to the embodiment, and because the integral air conditioner adopts all the technical schemes of all the embodiments, the integral air conditioner at least has all the beneficial effects brought by the technical schemes of the embodiments, and the details are not repeated here.

Without losing generality, the integrated air conditioner further comprises an electric control device 50, the electric control device 50 comprises a main control board 51, a large amount of heat can be generated when the main control board 51 works, and the running performance and the service life of the main control board 51 can be obviously affected if the heat cannot be timely discharged, so that the existing integrated air conditioner can select to specially configure a cooling fan for the electric control device 50 so as to assist the cooling fan. Referring to fig. 1 to 4, in an embodiment of the present invention, optionally, the electronic control device 50 is at least partially located in the outdoor airflow channel 10 e. So, the air flow generated during the operation of the first fan 23 can be directly utilized to timely take away the heat generated by the main control board 51, thereby improving the heat dissipation efficiency of the main control board 51 and ensuring the operation performance and the service life of the main control board 51. Compared with the prior art, the integral air conditioner does not need to be provided with the parts special for assisting the electric control device 50 in radiating, so that the structure of the integral air conditioner can be simplified, the miniaturization design of the integral air conditioner is facilitated, the storage and logistics costs of special auxiliary parts (such as a radiating fan arranged on the electric control device 50) can be saved, the production and assembly procedures of the integral air conditioner can be reduced, the production efficiency of the whole machine is improved, and the manufacturing cost of the whole machine is reduced. And secondly, because no special auxiliary parts are configured, the control logic of the integral air conditioner can be simplified, the operation reliability of the integral air conditioner is improved, and the failure rate and the after-sale maintenance cost are reduced.

Referring to fig. 3, 4 and 6, in an embodiment, the first heat exchanger 21 is disposed adjacent to the outdoor air outlet 10d, the first heat exchanger 21 is located at the air outlet side of the first fan 23, and the electric control device 50 is located at the air inlet side of the first fan 23. In this way, the electric control device 50 can be prevented from blocking the air flow blown to the first heat exchanger 21, thereby ensuring good heat exchange efficiency of the first heat exchanger 21. And, it is also possible to make the arrangement of the air conditioner internals in the first direction more compact. Of course, in other embodiments, the electric control device 50 may be disposed between the first fan 23 and the first heat exchanger 21.

Referring to fig. 3, 5, 6 and 9, in one embodiment, the outdoor air inlets 10c are provided with at least two groups, at least two groups of outdoor air inlets 10c are respectively disposed at the left side and the right side of the housing 10, the outdoor air outlets 10d are disposed at the rear side of the housing 10, and the electric control device 50 is disposed between the left side outdoor air inlet 10c and the right side outdoor air inlet 10 c. It should be noted that, for the car air conditioner, the left and right sides of the housing 10 refer to the left side of the housing 10 corresponds to the left side of the vehicle, the right side of the housing 10 corresponds to the right side of the vehicle, and the rear side of the housing 10 corresponds to the rear side of the car after the integrated air conditioner is mounted on the roof of the car. In this way, the air intake amount in the outdoor airflow passage 10e can be increased by simultaneously taking in air through the plurality of groups of outdoor air inlets 10c, thereby improving the heat exchange efficiency of the first heat exchanger 21. Next, the outdoor air outlet 10d is provided at the rear side of the casing 10, and the air flow in the outdoor air flow passage 10e smoothly flows out of the outdoor air outlet 10d regardless of whether the vehicle is running or not. Moreover, the air flowing in from the outdoor air inlets 10c at the left and right sides will flow through the electric control device 50 at the middle, so as to enhance the effect of taking away the heat of the electric control device 50, thereby improving the heat dissipation efficiency of the electric control device 50. Of course, in other embodiments, only one group of outdoor air inlets 10c may be provided; the outdoor air outlet 10d is arranged at the left side, the right side or the lower side of the shell 10; the electronic control device 50 is disposed near the outdoor air intake 10 c.

Referring to fig. 3, 4, 6, 10 and 11, wherein the thin dotted lines in fig. 10 and 11 indicate the flow direction of a part of the air flow in the unitary air conditioner; in one embodiment, the electronic control device 50 is disposed adjacent the top of the top cover 11 of the housing 10. That is, the electronic control device 50 is provided at a high position, so that it is possible to avoid the problem that the main control panel 51 is affected by water drops due to the rainwater entering the housing 10 through the outdoor air inlet 10c flying into the electronic control box 53. It should be noted that the integral air conditioner further comprises a compressor 60 connected between the first heat exchanger 21 and the second heat exchanger 22, and the compressor 60 and the electric control device 50 are separately arranged at the left side and the right side of the first fan 23, so that the limited arrangement space in the casing 10 can be reasonably utilized, thereby enabling the arrangement of internal parts of the integral air conditioner to be more compact and being beneficial to the miniaturization design of the integral air conditioner. Of course, in other embodiments, the electronic control device 50 may be disposed on the water collecting tray 12; alternatively, the electric control device 50 is located inside the outdoor air intake 10c, that is, the electric control device 50 is disposed adjacent to the outdoor air intake 10c, and the air flow reaches the electric control device 50 at the first time after entering the outdoor air intake 10 c.

Referring to fig. 2 to 4 and 6, in order to further improve the heat dissipation efficiency of the electric control device 50, in the embodiment of the integrated air conditioner provided with the water collecting tank 122 and the water pumping structure, optionally, the electric control device 50 further includes a heat dissipation structure 52 connected with the main control board 51, and an electric control box 53, the main control board 51 is located in the electric control box 53, and the heat dissipation structure 52 is exposed outside on the electric control box 53 and is disposed close to the water pumping structure. In this way, when the water beating structure hits the condensed water in the water collecting tank 122 and splashes the condensed water to the periphery, part of the condensed water can be directly thrown to the heat dissipation structure 52 and drop to the bottom of the shell 10 under the action of gravity, and the condensed water can take away the heat of the heat dissipation structure 52 in the process, so that the heat dissipation efficiency of the heat dissipation structure 52 is improved. In this embodiment, the air flow generated by the first fan 23 and the splashing condensed water generated by the water-spraying structure together play a good role in promoting the heat dissipation of the electric control device 50, so as to improve the overall heat dissipation efficiency of the electric control device 50. Of course, in other embodiments, the integral type air conditioner may not be provided with a water pumping structure and a water collecting structure, but the air flow of the outdoor air flow channel 10e is used to rapidly take away the heat of the electric control device 50, so as to improve the heat dissipation efficiency of the electric control device 50.

Referring to fig. 2, 6, 10 and 11, in an embodiment, an installation cavity is provided in the electric control box 53, the main control board 51 is disposed in the installation cavity, a box air inlet 531 is provided on a side of the electric control box 53 facing the outdoor air inlet 10c, a box air outlet 532 is provided on a side of the electric control box 53 facing the first fan 23, the box air inlet 531 is communicated with the installation cavity, and the box air outlet 532 is communicated with the installation cavity. Specifically, in this embodiment, alternatively, the left and right sides of the electric control box 53 are respectively provided with one outdoor air inlet 10c, so that the left and right sides are provided with box air inlets 531. In this way, the air flow flowing in from the outdoor air inlets 10c on the left and right sides can flow into the electric control box 53 through the box air inlet holes 531 on the two sides, and then flows out from the box air outlet holes 532 after flowing through the main control board 51, so that the heat on the main control board 51 is taken away more rapidly in time, and the heat dissipation efficiency of the electric control device 50 is further improved. Of course, in some embodiments, the electronic control box 53 may not be provided with the box air inlet hole 531 and the box air outlet hole 532, and only the air flows through the exposed heat dissipation structure 52. In other embodiments, the box inlet 531 is provided on only one side of the electronic control box 53, such as the left or right side.

Specifically, in the embodiment of the present invention, the electric control device 50 may be integrally disposed in the outdoor airflow channel 10e, and then the heat on the main control board 51 is timely taken away by using the airflow entering the installation cavity, and the heat dissipation structure 52 may be present or absent. Of course, the electronic control device 50 may just expose the heat dissipation structure 52 in the outdoor airflow channel, while hiding the rest.

Referring to fig. 6, 10 and 11, in one embodiment, the heat dissipation structure 52 is disposed outside the box air outlet 532. In this way, the heat dissipation structure 52 can prevent the splashed condensed water from entering the box air outlet 532, so as to avoid the problem that the condensed water enters the electric control box 53 and damages the main control board 51. In addition, the air flowing out from the electric control box 53 will first pass through the heat dissipation structure 52 and then flow to the first fan 23, so that the heat dissipation efficiency of the heat dissipation structure 52 can be further improved.

Specifically, the heat dissipation structure 52 has various structural forms, for example, referring to fig. 2, 6 and 10, in an embodiment, the heat dissipation structure 52 includes a plurality of heat dissipation fins, and the plurality of heat dissipation fins are disposed at intervals along a direction perpendicular to an axis of the first fan 23, and the heat dissipation fins extend along the axis direction of the first fan 23. In this way, the heat radiating area can be increased by the plurality of heat radiating fins, heat can be taken away more rapidly, and the heat radiating fins extend along the axial direction of the first fan 23, and the air flow passage between two adjacent heat radiating fins can extend toward the first fan 23, so that air flowing out from the electric control box 53 can flow through the heat radiating fins and flow to the first fan 23 more smoothly. In this embodiment, optionally, a plurality of heat dissipation fins are disposed at intervals in the left-right direction. Of course, in some embodiments, a plurality of heat dissipation fins may be disposed at intervals along the up-down direction. In other embodiments, the heat dissipating fins may be extended in a direction perpendicular to the axis of the first fan 23. In still other embodiments, the heat dissipation structure 52 may further include a heat dissipation plate, which extends in a left-right direction, and a plurality of ventilation holes are spaced on the heat dissipation plate.

Referring to fig. 6, in an embodiment, the electronic control device 50 is disposed adjacent to the top of the housing 10, and the opening direction of the box air outlet 532 extends obliquely downward toward the direction approaching the first fan 23. In this way, the air flowing out from the box air outlet 532 can smoothly flow down to the first fan 23, so that more air can flow to the first fan 23 intensively, and the smoothness and stability of the air flow field in the outdoor airflow channel 10e are improved, and the heat exchange efficiency of the first heat exchanger 21 is further ensured.

Referring to fig. 2 to 6, in one embodiment, the unitary air conditioner further includes an outdoor air duct 40 located in the casing 10, the outdoor air flow channel 10e is partially formed in the outdoor air duct 40, and the outdoor air duct 40 is located at one side of the water collection tank away from the outdoor air outlet 10 d; the blade portion of the axial flow wind wheel 232 extends out of the air outlet end of the outdoor air duct 40 and can extend into the water collecting tank 122 for water pumping. In this way, the stability of the air flow field in the outdoor air flow channel 10e can be improved, and the air flow blown to the first heat exchanger 21 is more concentrated, so that the change of the external air flow field in the running process of the vehicle is prevented from affecting the internal flow field obviously, and the heat exchange efficiency of the first heat exchanger 21 is further ensured. It should be noted that, in the embodiment in which the squeeze-up structure 125 is protruded on the bottom surface of the water collecting tray 12 and the squeeze-up structure 125 is configured as a boss, the bottom of the outdoor air duct 40 is at least partially supported on the boss. Of course, in other embodiments, the outdoor air duct 40 may not be provided.

Referring to fig. 4 and 6, in an embodiment, the air outlet end of the outdoor air duct 40 is spaced from the outdoor air outlet 10d, and the first heat exchanger 21 is located between the air outlet end of the outdoor air duct 40 and the outdoor air outlet 10 d. In this way, the structure of the outdoor air duct 40 is simplified on the premise that the air flow can more intensively flow to the first heat exchanger 21, thereby reducing the manufacturing cost of the unitary air conditioner. Of course, in other embodiments, the air outlet end of the outdoor air duct 40 may be abutted against the inner edge of the outdoor air outlet 10d, and the first heat exchanger 21 may be disposed in the outdoor air duct 40.

Referring to fig. 6, in an embodiment, the heat dissipation structure 52 is adjacent to the air inlet end of the outdoor air duct 40, the first fan 23 includes an axial flow wind wheel 232, and a blade portion of the axial flow wind wheel 232 extends out of the air inlet end and can throw water towards the heat dissipation structure 52. In this way, the part of the vane extending out of the outdoor air duct 40 can throw the condensed water towards the heat dissipation structure 52, so that the condensed water hit by the water beating structure can still cool the heat dissipation structure 52. Of course, in some embodiments, the heat dissipation structure 52 may be disposed at the air inlet end of the outdoor air duct 40, so that the condensed water thrown by the water throwing structure can be smoothly splashed to the heat dissipation structure 52 also disposed in the outdoor air duct 40. In other embodiments, the heat dissipation structure may be located between the first fan and the first heat exchanger, where condensed water thrown by the water throwing structure may not be required to be splashed directly towards the heat dissipation structure, but the thrown condensed water may be blown towards the heat dissipation structure by means of an air flow blown towards the first heat exchanger.

The foregoing description is only of the optional embodiments of the present invention, and is not intended to limit the scope of the invention, and all the equivalent structural changes made by the description of the present invention and the accompanying drawings or the direct/indirect application in other related technical fields are included in the scope of the invention.
