It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Thus, a feature indicated in this specification will serve to explain one of the features of one embodiment of the utility model, and does not imply that every embodiment of the utility model must have the stated feature. Further, it should be noted that this specification describes many features. Although some features may be combined to show a possible system design, these features may also be used in other combinations not explicitly described. Thus, the combinations illustrated are not intended to be limiting unless otherwise specified.

The principles and construction of the present invention will be described in detail below with reference to the drawings and examples.

In the prior art, in order to increase the air speed of an air conditioner indoor unit and increase the air volume, a blowing type air supply mode is usually adopted, in order to avoid blowing out of condensed water when a fan operates, a water retaining block water retaining mode is adopted in the prior art, but the structure and the arrangement design of the water retaining block water retaining plate can avoid blowing out of the condensed water, the backflow of the condensed water is also influenced, when the fan stops operating, the condensed water is easily accumulated, accumulated water is generated, and bad experience is brought to a user.

Referring to fig. 1, the present invention provides a water-blowing-proof water pan, which includes a water pan main body 1, and at least one water-blocking block 2 laid on the water pan main body 1, each water-blocking block 2 includes a flow-limiting portion 21 disposed on a windward side thereof, and a flow-guiding portion 22 disposed on a leeward side thereof, wherein the flow-limiting portion 21 is capable of blocking the flow of air flow, so as to prevent condensed water from blowing out along with the air flow, and the flow-guiding portion 22 is used for guiding liquid to flow downward, so that the liquid flows into the water pan main body 1, and is convenient for discharging.

Specifically, please refer to fig. 3, a plurality of rows of water retaining blocks 2 are laid on the water pan body 1, each row of water retaining blocks 2 are arranged along a straight line, and the arrangement directions between any two rows of water retaining blocks 2 are parallel to each other, so that the arrangement mode can save the occupied area of the water retaining blocks 2 to the maximum degree, and simultaneously, a better blocking effect is achieved. If the arrangement directions of any two rows of water blocking blocks 2 are intersected, the distance between the two rows of water blocking blocks 2 is different, more space can be occupied, and because the two rows of water blocking blocks are intersected, the air flow direction can only be perpendicular to one row of water blocking blocks 2 and is intersected with the arrangement direction of the other row of water blocking blocks 2, and because the air flow direction is perpendicular to the arrangement direction of the water blocking blocks 2, the wind shielding effect is best, namely the optimal blocking effect cannot be achieved by the row of water blocking blocks 2 which are not perpendicular to the air flow direction, so that the arrangement directions of the rows of water blocking blocks 2 are arranged in parallel, and the blowing-out of condensed water is blocked.

Preferably, the arrangement direction of each row of water blocking blocks 2 is perpendicular to the air flow direction, and the water blocking blocks 2 can play the best water blocking effect in the arrangement mode.

Further, two adjacent rows of water blocking pieces 2 are arranged in a vertically staggered manner, so that the flow limiting parts 21 of the water blocking pieces 2 in the first row are arranged between the drainage parts 22 of the two water blocking pieces 2 in the second row adjacent to the first row, meanwhile, gaps are formed between all the adjacent water blocking pieces 2 to form drainage grooves, when the fan stops running, condensed water on the water blocking pieces 2 in the first row flows into the drainage grooves on two sides of the drainage parts 22 under the guide of the drainage parts 22, then flows into the drainage parts 22 of the water blocking pieces 2 in the second row through the drainage grooves, flows into the drainage grooves on two sides of the drainage parts 22 through the guide of the drainage parts 22 of the water blocking pieces 2 in the second row, and enters the drainage parts 22 of the water blocking pieces 2 in the third row until the condensed water flows into the bottom of the water receiving tray main body 1 after the condensed water flows into the last row for drainage. Through this mode of setting up, can form a decurrent passageway through each diversion flume, on the drainage portion of water blocking piece 2 was all arranged in to this passageway, can guide the discharge of comdenstion water, played better drainage effect.

Correspondingly, when the fan operates, the condensed water flows upwards along with the air flow direction, and is blocked by the flow limiting part 21 of the last row of water blocking blocks 2 firstly, so that the condensed water is prevented from being discharged, and even if the condensed water flows into the last row of water blocking blocks 2 from the gap between the two water blocking blocks 2, the condensed water is blocked by the flow limiting part 21 in the row of water blocking blocks 2, and the condensed water is prevented from being blown out. Through this setting mode, can block blowing out of comdenstion water layer upon layer, strengthen it and block the effect.

Referring to fig. 1 and 2, preferably, the height of the drip tray body 1 is gradually increased along the airflow direction, and the outer surface of the drip tray body forms a slope, the height of the slope is increased along the airflow direction, when the condensed water blows upwards along the airflow direction, the slope is influenced by gravity, so that the blowing of the condensed water is further blocked, and meanwhile, when the fan stops running, the condensed water above the slope gradually flows downwards due to the gravity, so that the condensed water flows back to the lowest position of the drip tray body 1. It can be seen that through the setting on slope, can further strengthen the water collector and block the effect that the comdenstion water blew off, can also increase the effect that the water collector drainage was blown off, and the structure is more simple, design and preparation of being convenient for.

Further, the water blocking block 2 is arranged on the slope, a drainage assembly is arranged below the slope, and condensed water is discharged through the drainage assembly, so that accumulation of the condensed water is avoided, and inconvenience is brought to users.

The drainage assembly can be designed into a drainage hole, so that condensed water can be drained through the drainage hole, the arrangement mode is simplest, and the cost is lowest. In other embodiments of the present invention, the drainage assembly may be in the form of a water pump, and the drainage assembly drains the condensed water through the water pump, which has the advantages of controllable drainage time and speed and better adaptability to various use environments.

Furthermore, the edge of the water pan body 1 is provided with a stop 3 for preventing the condensed water from being discharged from the edge of the water pan body 1, and the setting mode of the stop 3 can be designed by being integrally formed with the shell of the water pan, so that the condensed water is prevented from being blown out under the condition that the attractiveness of the water pan is not influenced.
