[0036] In the related art, a drainage structure is generally provided at the bottom of the evaporator of a mobile air conditioner. Such a drainage structure generally collects condensed water through a pipeline to a water receiving tank or conveys it to the outside of the mobile air conditioner. Due to the large volume of the evaporator, the design of the drainage structure is complicated, there are many matching pipelines and the installation is messy and not centralized, which affects the overall structural layout of the mobile air conditioner and results in the installation of components inside the mobile air conditioner not being compact enough.

[0037] In view of the technical problems involved in the related art, the present utility model provides a mobile air conditioner with a drainage structure. By improving the drainage structure inside the mobile air conditioner, the internal pipeline arrangement is simplified, making the structure of the mobile air conditioner compact.

[0038] Reference Figures 1 to 7 The mobile air conditioner with a drainage structure according to an embodiment of the present utility model will be described below, and specific embodiments will be listed for illustration.

[0039] Refer to Figure 1As shown in the figure, the mobile air conditioner includes a first water receiving part 310, a second water receiving part 410 and a third water receiving part 500. The worm wheel for driving the gas flow in the condenser 200 air duct is located in the middle of the mobile air conditioner. The volute casing for installing the worm wheel is divided into upper and lower parts, namely a first casing 300 and a second casing 400. The first casing 300 and the second casing 400 are snap-connected through a limiting structure to form a complete volute casing. The first water receiving part 310 is located at the top of the first casing 300, and the second water receiving part 410 is located above the extension part on the side of the second casing 400. The third water receiving part 500 is located inside the bottom case of the mobile air conditioner. The second water receiving part 410 is located above the condenser 200, and the third water receiving part 500 is located below the condenser 200.

[0040] It can be understood that the function of the first water receiving part 310 is to collect the condensed water on the surface of the evaporator 100 and then transport the condensed water to the second water receiving part 410. That is to say, the condensed water on the surface of the evaporator 100 will flow downward along the outside of the evaporator 100 to the first water receiving part 310. The width of the first water receiving part 310 in the horizontal direction is greater than the width of the evaporator 100 in the horizontal direction, so that the condensed water will not flow outside the first water receiving part 310, and the slight shaking of the mobile air conditioner will not throw the condensed water out of the range of the first water receiving part 310.

[0041] In addition, the second water receiving part 410 can receive and transfer the condensed water collected by the first water receiving part 310. The second water receiving part 410 can be connected to an external drain pipe to transport the condensed water outside the housing of the mobile air conditioner, and can also send the condensed water to the surface of the condenser 200, which has a certain cooling effect on the condenser 200. The excess condensed water will flow downward along the surface of the condenser 200 to the third water receiving part 500.

[0042] Refer to Figure 2 and Figure 3 As shown in the figure, the first water receiving part 310 is provided with a plurality of water separation plates 311. The plurality of water separation plates 311 are arranged along a first direction. The length direction of the water separation plate 311 is a second direction, and the first direction is perpendicular to the second direction. Adjacent two water separation plates 311 define a drainage channel 312, that is, the first water receiving part 310 is provided with a plurality of drainage channels 312, and the plurality of drainage channels 312 are parallel to each other. Since the first casing 300 is square, in order to adapt to the structure of the first casing 300, the drainage channel 312 is provided with a bending part, that is, the water separation plate 311 has a bending position, which can increase the conveying distance of the drainage channel 312, so that the condensed water on the surface of the evaporator 100 can freely fall into the drainage channel 312. The bending part of the drainage channel 312 is located in the middle position.

[0043] It should be noted that a first drainage hole 313 is provided in the drainage channel 312, and an inclined surface is provided at the bottom of the drainage channel 312, with the lowest point of the inclined surface located at the first drainage hole 313. Specifically, the first drainage hole 313 is located at the end of the drainage channel 312. Four inclined surfaces are provided in the drainage channel 312, and the intersection of the four inclined surfaces is the position of the first drainage hole 313. The condensed water falling into the drainage channel 312 will gather along the inclined surface to the first drainage hole 313, effectively preventing the condensed water from accumulating in the drainage channel 312 and thus preventing the breeding of mosquitoes and bacteria.

[0044] The arrangement of the drainage channel 312 is not limited to the above form. In some other embodiments, the first water receiving part 310 may be provided with one drainage channel 312, and one inclined surface is provided in the drainage channel 312. The higher end of the inclined surface is located at one end of the drainage channel 312, and the lower end of the inclined surface is located at the other end of the drainage channel 312. Other similar forms of arrangement are also possible. The function of the inclined surface is to concentrate the condensed water to the first drainage hole 313. The inclined surface can also be replaced with an arc surface, and its function is the same as that of the above inclined surface, and no detailed description will be given here.

[0045] In addition, the first water receiving part 310 is further provided with an arc part 3130 for guiding the flow of the first drainage hole 313. The setting of the arc part 3130 can effectively reduce the liquid surface tension at the entrance of the first drainage hole 313, and the condensed water can flow out of the first drainage hole 313 more smoothly.

[0046] It should be noted that the water isolation plate 311 is further provided with a notch 3110 for communicating two adjacent drainage channels 312. Such a design can reduce the situation of the condensed water overflowing in the drainage channel 312. After the condensed water flows into one drainage channel 312, it will flow to other drainage channels 312 along the notch 3110. Only when all the drainage channels 312 are filled with condensed water, the condensed water may overflow.

[0047] It should be noted that the first water receiving part 310 is further provided with a support plate 314, and the support plate 314 is located outside the drainage channel 312, and the height of the support plate 314 is greater than the height of the water isolation plate 311. Such a design can prevent the condensed water overflowing from the drainage channel 312 from flowing outside the housing of the mobile air conditioner and causing water leakage.

[0048] Refer to Figure 4 and Figure 5As shown, the second water receiving part 410 is provided with a plurality of second drain holes 411. The condensed water in the first water receiving part 310 flows from the first drain hole 313 to the second water receiving part 410 and then flows out from the second drain holes 411. The second water receiving part 410 is further provided with a plurality of steps 412. The steps 412 are circumferentially arranged at the ends of the second drain holes 411, and the plurality of steps 412 have a height difference. The function of the steps 412 is to divert the condensed water in the second water receiving part 410, which can improve the drainage efficiency of the condensed water.

[0049] It should be noted that the steps 412 are further provided with a convex part 4120. One end of the convex part 4120 far away from the steps 412 extends horizontally. The height of the end of the convex part 4120 connected to the steps 412 is greater than the height of the end of the convex part 4120 far away from the steps 412. The purpose of setting the convex part 4120 is to reduce the liquid surface tension at the second drain holes 411, and the convex part 4120 also has a guiding effect on the condensed water, thereby improving the drainage efficiency of the condensed water.

[0050] In addition, the second water receiving part 410 is further provided with a drainage groove 413. The drainage groove 413 extends to the outside of the second water receiving part 410, and the end of the drainage groove 413 is used to connect an external drainage pipe. The function of the drainage groove 413 is to guide the condensed water to flow out of the second water receiving part 410, that is, the condensed water can not only flow out from the second drain holes 411, but also flow out from the drainage groove 413.

[0051] Refer to Figure 6 and Figure 7 As shown, a first drainage pipe 315 is provided on the lower side of the first water receiving part 310. The first drainage pipe 315 communicates with the first drain hole 313. The first drainage pipe 315 points to the second water receiving part 410. A second drainage pipe 414 is provided on the lower side of the second water receiving part 410. The second drainage pipe 414 communicates with the second drain holes 411. The second drainage pipe 414 points to the condenser 200. The function of the first drainage pipe 315 is to guide the condensed water in the first drain hole 313 to flow towards the second water receiving part 410, and the function of the second drainage pipe 414 is to guide the condensed water in the second drain holes 411 to flow towards the condenser 200.

[0052] It should be noted that cuts are provided at the ends of the first drainage pipe 315 far away from the first drain hole 313 and the ends of the second drainage pipe 414 far away from the second drain holes 411. The function of the cuts is to reduce the liquid surface tension in the first drainage pipe 315 and the second drainage pipe 414, so that the condensed water can flow out more smoothly.

[0053] The above has described the embodiments of the present invention in detail with reference to the drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present invention.
