[0029] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0030] Referring to Figures 1 - 10 , the present utility model provides a drainage structure for the waste water of a mobile air conditioner, which includes a volute upper plate 1. The volute upper plate 1 is a rectangular plate structure arranged horizontally as a whole. An installation area 1a is provided on the upper surface of the volute upper plate 1. The installation area 1a is close to one edge of the volute upper plate 1 and is used for installing an evaporator. A water retaining ring is provided on the edge of the installation area 1a to prevent the condensed water generated by the evaporator from flowing out. In this embodiment, the edge of the volute upper plate 1 is bent upward by 90 degrees to form a strengthening part. At the same time, a water retaining strip 11 is provided on the upper surface of the volute upper plate 1. Both ends of the water retaining strip 11 are connected to the strengthening part. An installation area is formed between the water retaining strip 11 and the strengthening part. The water retaining strip 11 and the strengthening part serve as a water retaining structure, that is, a water retaining ring is formed. A supporting part 21 is provided on the bottom surface of the installation area 1a. The supporting part 21 is used to contact the bottom of the evaporator, so as to support the evaporator. Supports 22 are provided at both ends of the installation area 1a. The supports 22 are used to connect with the evaporator to fix the evaporator. An installation hole is provided on the support 22 for fixedly connecting with the evaporator through bolts (screws). A downward groove structure is provided on the bottom surface of the installation area 1a to form a water collecting tank 10. The water collecting tank 10 is used to allow the condensed water in the installation area 1a to flow in and be collected. A first drain pipe 31 and a second drain pipe 32 are provided in the water collecting tank 10. The first drain pipe 31 extends vertically downward and is used to dock with the pipe body on the volute lower plate, so as to discharge the condensed water in the water collecting tank 10 (installation area 1a) to the lower end and be used to cool the condenser, realizing waste water drainage. The first drain pipe is a hard pipe and is integrally formed with the volute upper plate 1 by injection molding; the second drain pipe 32 extends backward. Preferably, it extends horizontally backward. When used in an environment with high humidity, drainage can be carried out through the second drain pipe, avoiding excessive condensed water discharged downward from causing water accumulation at the lower end and causing alarm shutdown; A plug 321 or a drainage hose is selectively installed at the outlet end of the second drain pipe, that is, it can be selected to install or not install according to the use requirements. When the plug is installed, the condensed water is drained out through the first drain pipe. When the plug is not installed, the condensed water is preferentially discharged from the second drain pipe, avoiding excessive condensed water entering the lower end of the air conditioner through the first drain pipe. Opening the second drain pipe in an environment with high humidity can ensure the continuous and stable operation of the mobile air conditioner, improve its environmental adaptability, and avoid the problem of frequent alarms in a high humidity environment. It is flexible to use and has a wide application range.

[0031] In this application, the support part 21 includes a plurality of horizontally arranged strip-shaped protrusions. The top surface of the strip-shaped protrusions forms a support surface for supporting the evaporator. Preferably, the strip-shaped protrusions are linear, there are multiple of them and they are arranged in parallel. The length direction thereof is parallel to the length direction of the installation area 1a. There is a gap between adjacent two strip-shaped protrusions to form a flow-through channel. The water collecting tank 10 is located on the flow path of the flow-through channel. Therefore, the condensed water can quickly enter the water collecting tank 10 under the guidance of the flow-through channel. In order to improve the water guiding efficiency and effect, in this embodiment, the bottom surface of the installation area 1a is an inclined surface, which can guide the condensed water into the water collecting tank. Since the upper plate 1 of the volute is an overall horizontally arranged plate-like structure, the inclination angle is small. Preferably, it is 0.5 - 1°, which can make all the condensed water in the installation area 1a flow together into the water collecting tank.

[0032] The upper end of the first drain pipe 31 extends upward into the water collecting tank 10 to form a water inlet pipe 311. The top of the water inlet pipe 311 serves as the water inlet end, or a water inlet hole 310 is opened on the side wall of the water inlet pipe 311. At this time, the water inlet hole 310 serves as the water inlet end. Whether the top serves as the water inlet end or the water inlet hole 310 serves as the water inlet end, its height is higher than the bottom surface of the water collecting tank 10 to form a height difference, that is, the water inlet end is located at the upper end of the bottom surface of the water collecting tank body 10. There is a certain height difference between the lower part of the water inlet end and the bottom surface of the water collecting tank 10. The water at this position cannot be discharged from the first drain pipe, which can prevent the debris particles at the lower end of the accumulated water from entering the first drain pipe and avoid problems such as blockage caused by debris entering the lower cooling area, improving the use stability and reliability. When the water in the water collecting tank is higher than or level with the water inlet end, it enters the first drain pipe. The second drain pipe 32 is horizontally arranged, and its water inlet end is lower than or level with the bottom surface of the water collecting tank 10. When the second drain pipe 32 is opened, it can discharge the debris particles at the bottom of the water collecting tank. At the same time, due to the height difference between the water inlet ends of the first drain pipe and the second drain pipe, the second drain pipe 32 drains water prior to the first drain pipe, which can discharge the condensed water to the outside of the air conditioner in a high-humidity environment and avoid too much condensed water entering the lower end of the mobile air conditioner and causing alarm shutdown. During use, a hose is externally connected to the second drain pipe. In order to improve the connection reliability, one or more annular anti-slip grooves are provided on the side wall of the second drain pipe 32 to prevent the hose from loosening. The cross-section of the anti-slip groove is triangular, which is convenient for the hose to be inserted inward and has an anti-slip effect to prevent the hose from slipping out and falling off.

[0033] An upper volute 4 is provided on the lower bottom surface of the volute upper plate 1. A reinforcing rib 41 is provided between the side wall of the first drain pipe 31 and the side wall of the upper volute 4. The reinforcing rib 41 is a plate structure, and its two sides are respectively connected to the side wall of the upper volute 4 and the first drain pipe, and the top is connected to the bottom surface of the volute upper plate 1, so as to improve the structural strength of the first drain pipe 31 and prevent it from deflecting or even breaking. During assembly, the end of the first drain pipe 31 can be sleeved on the pipe body on the volute lower plate, and then the condensed water can be discharged to the water-throwing cooling area at the lower end, thereby cooling the condenser.

[0034] In this application, the water collecting tank 10 is arranged at the end of the installation area 1a, and the middle position is for the volute to discharge air. The water collecting tank 10 has a first side wall 10a and a second side wall 10b. Among them, the first side wall 10 is on the side far from the end, and the amount of condensed water on this side is relatively large. The first side wall 10a is an inclined surface with an inclination angle of 30 degrees to 60 degrees. The second side wall 10b is at the end close to the end, and it is arranged opposite to the first side wall. The inclination angle of the second side wall 10b is smaller. In this embodiment, the second side wall is a vertical surface, and the lower end of the second side wall is connected to the bottom surface of the water collecting tank 10 through an arc surface 10c. A part of the water inlet pipe is located on the first side wall 10a, and the water inlet hole 310 is arranged on the side facing away from the first side wall to prevent condensed water from directly entering the water inlet hole.

[0035] The water drainage structure of the mobile air conditioner of the present utility model is provided with a support structure to provide sufficient flow space for the condensed water, improve the fluidity and collection efficiency of the condensed water; the support structure adopts strip-shaped convex ribs, which have a large support area and high reliability. At the same time, an overflow channel is formed between adjacent convex ribs, and the flow direction of the condensed water is good, thereby improving the flow and collection efficiency; adopting a double-drain pipe structure can selectively drain water, avoid the machine from alarming and shutting down due to excessive condensed water, and can continuously and stably work in a high-humidity environment, overcoming the limitations of the existing mobile air conditioners and providing a good user experience; the water inlet end of the first drain pipe is higher than the ground of the water collecting tank, which can prevent particulate debris from entering and blocking the lower pipe body, improve the overall reliability and stability of use. At the same time, a height difference is formed with the water inlet end of the second pipe body, so that the second pipe body drains water prior to the first drain pipe, and can quickly drain the condensed water in a high-humidity environment to avoid alarming and shutting down; a reinforcing rib structure is provided to improve the structural strength of the first drain pipe and prevent deformation or even damage, and at the same time facilitate quick assembly; the water drainage structure of the mobile air conditioner of the present utility model is compact, has a double-drainage structure, can continuously work in a high-humidity environment, has good use effects and a wide application range.

[0036] The above are only the preferred embodiments of the present utility model.
