Description

Technical Field

[0001] This utility model relates to a portable air conditioner, and more particularly to a portable air conditioner drainage and cooling structure. Background Technology

[0002] Portable air conditioners do not need to be installed on windows or walls; they are placed on the ground and can be moved anytime, anywhere. They are convenient to use, require no professional installers, and can be easily placed and connected to a power source. As a result, the use of portable air conditioners is becoming increasingly widespread.

[0003] Portable air conditioners use built-in condensers and evaporators, and the heat dissipation of the condenser determines the overall cooling effect of the portable air conditioner. In the existing technology, the condenser is cooled by splashing water at the bottom. However, in the process of splashing water at the bottom, the water can only be splashed to the bottom of the condenser and cannot be splashed to the top of the condenser. The cooling area is limited, so the cooling effect is not ideal and affects the overall cooling effect of the portable air conditioner. Utility Model Content

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] See Figures 1-13 This utility model provides a drainage and cooling structure for a portable air conditioner, used for draining water and cooling the condenser. It includes a housing 1, which is a rectangular parallelepiped with a hollow interior forming a mounting cavity for mounting components. A partition 2 is horizontally positioned within the housing 1, dividing the mounting cavity into an upper and lower cavity. An evaporator 3 is housed in the upper cavity, and a condenser 4 is housed in the lower cavity. A water collection area 2a and a drainage area 2b are provided on the upper surface of the partition 2, and these areas are interconnected. The water collection area 2a is parallel to the length direction of the partition 2, while the drainage area 2b is parallel to the width direction of the partition 2. That is, the length direction of the water collection area 2a is perpendicular to the length direction of the drainage area 2b. Correspondingly, during installation, the length direction of the evaporator 3 is perpendicular to the length direction of the condenser 4, which is conducive to the optimized arrangement of the air duct. In this application, the water collection area 2a and the drainage area 2b are set at the edge of the partition. That is, after installation, the evaporator 3 and the condenser 4 are both set near the edge of the shell, and the two are located on different surfaces of the shell 1.

[0034] In this embodiment, the partition 2 is a rectangular partition body 21 with its edges bent upwards to form edge portions. A partition plate is provided inside the partition body 21, dividing the partition body 21 into a first area and a second area. The first area is used to install components such as air ducts, and the second area has an L-shaped structure, including a water collection area 2a and a drainage area 2b. The bottom surface of the water collection area 2a is higher than the bottom surface of the drainage area 2b, thus allowing condensate in the water collection area 2a to be diverted to the drainage area 2b. A partition plate is provided inside the water collection area 2a. The device includes mounting columns 22 and support parts 24. Multiple mounting columns 22 have screw holes on their top surfaces for fixing the evaporator 3 to the partition plate 2 using screws. Specifically, the evaporator 3 is installed in the water collection area 2a. The top of the support part 24 contacts the bottom surface of the evaporator 3, thereby supporting the evaporator 3 and improving its installation stability and reliability. In this application, four mounting columns 22 are arranged in a rectangular pattern. Two mounting columns 22 on the same side are connected by a baffle plate 23. (See reference...) Figure 8 The length of the baffle plate 23 is parallel to the length of the evaporator 3, that is, parallel to the length of the water collection area 2a. Two parallel baffle plates 23 are formed between the four mounting columns 22, and an inner drainage area is formed between the two baffle plates 23. This area is mainly used to collect and drain the condensate on the evaporator, improving the drainage efficiency. The end of the inner drainage area is connected to the drainage area 2b. There is a gap between the outer side of the baffle plate 23 and the inner wall of the water collection area 2a, forming an outer drainage area. The end of the outer drainage area is also connected to the drainage area 2b. By setting the outer drainage area, the condensate on the evaporator and the air duct can flow into this water collection area, improving the condensate collection rate. In order to allow the condensate in the water collection area 2a to flow quickly into the drainage area 2b, the bottom surface of the water collection area 2a is a slope, which is inclined towards the drainage area 2b. (See reference...) Figure 13 Its tilt angle is 0.5°-1°; the support part 24 is a strip-shaped protrusion, which is set between two baffles 23. The length direction of the support part 24 is parallel to the length direction of the baffles 23, so it will not obstruct the flow of condensate. Its top surface can contact the bottom of the evaporator to achieve support and improve the installation stability and reliability of the evaporator.

[0035] After assembly, the bottom surface of the partition 2 is fixedly connected to the top of the condenser 4. Meanwhile, the drainage area 2b is located directly above the condenser 4. Drip holes 200 are provided on the bottom surface of the drainage area 2b. The drip holes 200 are used for drainage and cooling the condenser 4. There are multiple drip holes 200 arranged sequentially along the length of the condenser 4. Preferably, they are arranged at equal intervals. During the drainage process, the drip holes drain water in the form of dripping water. Through dripping water, the water can fully contact the condenser, improving the cooling efficiency and effect. At the same time, the simultaneous dripping of multiple drip holes increases the cooling coverage area of ​​the condenser. In addition, combined with the water spraying at the bottom, the cooling efficiency and effect of the condenser can be greatly improved, thus improving the overall cooling effect of the portable air conditioner.

[0036] A strip-shaped protrusion is provided on the bottom surface of the partition plate 2 to form an installation limiting part 26. The installation limiting part 26 is located directly below the drainage area 2b. It is a strip-shaped rectangular structure, and its length direction is parallel to the length direction of the drainage area 2b. A groove 261 is provided on the bottom surface of the installation limiting part 26 so that the drip hole 200 can be connected to the lower cavity to realize drip drainage. In this application, multiple grooves 261 are provided at the lower end of the installation limiting part 26, which correspond one-to-one with the drip hole 200, that is, one groove corresponds to one drip hole. Through the above structural setting, the overall structural strength of the installation limiting part 26 can be increased, and the reliability and stability of the connection with the condenser can be improved.

[0037] The mounting limiting part 26 has a rectangular cross-section, and its ends can contact the side plates on both sides of the condenser 4, thereby achieving axial limiting, i.e., axial positioning along the length of the condenser. Two connecting parts are also provided on the bottom surface of the partition plate 2, located at both ends of the mounting limiting part 26, for connecting with the side plates of the condenser, thereby achieving a fixed connection between the two. For details, please refer to... Figures 9-12The mounting section includes a first mounting section 28 and a second mounting section 29. The first mounting section 28 is located at the head of the mounting limiting section and has a gap with the head of the mounting limiting section 26, forming a slot 260. The slot 260 accommodates the first side plate 42 of the condenser 4 inserted from bottom to top. A first mounting hole is formed on the side wall of the first mounting section 28, the axis of which is perpendicular to the end face of the mounting limiting section, for connection to the first side plate 42 via screws. A screw hole coaxial with the first mounting hole is also formed on the end face of the mounting limiting section. Simultaneously, the edge of the first side plate 42 is bent outwards at 90 degrees to form a reinforcing plate. This reinforcing plate contacts the side wall 281 of the first mounting section 28, thereby achieving radial limiting of the condenser, i.e., when the first side plate 42 is bent outwards... After the plate is inserted into the slot from bottom to top, the reinforcing plate is pushed to fit against one side wall 281 of the first mounting part 28. After fitting, the mounting holes on the first mounting part and the first side plate are coaxial, achieving precise positioning. At this time, it can be installed and fixed by screws. The bottom surface of the second mounting part 29 is a plane, which is parallel to the bottom surface of the partition 2, forming a limiting surface 29a. A second mounting hole 290 is opened on the limiting surface 29a. At the same time, the top of the second side plate 43 of the condenser 4 is bent outward by 90 degrees to form a mounting surface 431. The mounting surface 431 can fit against the limiting surface 29a, and a third mounting hole corresponding to the second mounting hole 290 is opened on the mounting surface 431 for fixing the second side plate to the partition by screws, thereby achieving the fixed installation of the entire condenser.
