Abstract
Description
Technical Field
[0001] The utility model relates to the field of air conditioners, and in particular to a fresh air module and an air conditioner cabinet. Background Art
[0002] When the air conditioner is turned on for a long time, the air in the room will become dirty and the oxygen content will decrease. People staying in such an environment will often experience adverse reactions such as dizziness and chest tightness. In order to solve the above problems, more and more air conditioners have built-in fresh air functions, which can transport fresh air from the outdoor side into the room through the fresh air module to improve the air quality.
[0003] The fresh air module is usually placed inside the air conditioner and wrapped with insulation material to prevent the air drawn into the fresh air module from having a large temperature difference with the fresh air module shell and generating condensation water. In order to obtain a good insulation effect, multiple sets of insulation materials are usually pasted on the fresh air module shell, which can easily lead to low production efficiency. At the same time, there may also be risks such as the insulation material not being pasted in place or falling off, which in turn affects the insulation effect of the fresh air module and affects product reliability. In addition, during the operation of the air conditioner cabinet, condensation water may also be generated at locations such as the heat exchanger, air outlet, and air inlet. When the condensation water is not drained smoothly, it is easy for the condensation water to drip into the cavity, causing the air conditioner to leak. Utility Model Content

[0029] like Figures 2 to 5 A fresh air module shown includes a fan assembly 1 and an air inlet box 2. The fan assembly 1 is provided with an air outlet 101 for discharging air, and the air inlet box 2 is provided with an air inlet 201 for taking in air. The fan assembly 1 is fixedly mounted above the air inlet box 2, and the air outlet 101 of the fan assembly 1 is connected to the air inlet 201 of the air inlet box 2. The fan assembly 1 also includes a water receiving pan 3, which is arranged around the periphery of the air inlet box 2. The water receiving pan 3 is located between the air inlet box 2 and the air outlet 101. The periphery of the water receiving pan 3 is provided with a rib 33 protruding upward, and the water receiving pan 3 is provided with a drainage hole 301. The condensed water dripping from the fan assembly 1 and the upper cavity of the air conditioner cabinet is collected by providing the water receiving pan 3, and the collected condensed water is gathered in the water receiving pan 3 by the rib 33, so as to prevent the condensed water from overflowing and increase the strength of the water receiving pan 3. The condensed water in the water receiving pan 3 is discharged to the outside of the air conditioner by providing the drainage hole 301. The drainage hole 301 is usually connected to a drainage pipe.
[0030] In the utility model, the air inlet box 2 is composed of a front air inlet box 21 and a rear air inlet box 22 fixedly spliced together, and the air inlet port 201 is opened at the lower part of the rear air inlet box 22; the water collecting tray 3 includes a front water collecting tray 31 and a rear water collecting tray 32, the front water collecting tray 31 is fixedly installed or integrally formed on the front air inlet box 21, and the rear water collecting tray 32 is fixedly installed or integrally formed on the rear air inlet box, the front water collecting tray 31 is located above the rear water collecting tray 32, so that there is a height difference between the front water collecting tray 31 and the rear water collecting tray 32, and a drip nozzle 311 is provided on the side of the front water collecting tray 31 close to the rear water collecting tray 32, and the drip nozzle 311 is used to drain the condensed water in the front water collecting tray 31 to the rear water collecting tray 32, and the drainage hole 301 is opened on the rear water collecting tray 32.
[0031] In order to ensure that the condensed water in the front water receiving tray 31 can be completely caught by the rear water receiving tray 32 after dripping from the drip nozzle 311, the drip nozzle 311 is located above the rear water receiving tray 32 and partially overlaps with the rear water receiving tray 32. Furthermore, the distance between the overlapping portion of the drip nozzle 311 and the rear water receiving tray 32 is not less than 3 mm.
[0032] In the present invention, the drip nozzle 311 is formed by a portion of the front water receiving tray 31 that is concave downwards near the rear water receiving tray 32 .
[0033] In the present invention, the drainage hole 301 is provided on a side of the rear water receiving tray 32 away from the front water receiving tray 31, and the side of the rear water receiving tray 32 on which the drainage hole 301 is provided is tilted downward. This can improve the smoothness of drainage and prevent condensed water from accumulating in the rear water receiving tray 32. Furthermore, the tilt angle of the rear water receiving tray 32 is not less than 2°, so that the condensed water in the rear water receiving tray 32 can quickly gather at the drainage hole position, thereby improving the drainage speed.
[0034] The air inlet box 2 is provided with a filter for filtering fresh air.
