If the equipment is placed in a building installation location, the drainage will be scattered, which can easily lead to complaints from residents. At present, the industry generally uses multiple plastic drain nozzles to converge into one outlet for drainage. Because the drain nozzles are too small, they are easily clogged by silt formed by external dust, resulting in poor drainage. The silt inside the drain nozzles needs to be cleaned frequently. In addition, there are also drain pans made of sheet metal stamping parts on the market. The drain pan is square box-shaped with a drain nozzle arranged on its side. The drain pan must be installed with one side high and the other side low to form a certain slope for drainage, which affects the aesthetics of the product installation.
[0003] When the device is used in northern areas (ambient temperatures below 0°C), ice can easily form on the drain nozzle and drain pan, causing ice to form on the device, posing a safety hazard to pedestrians downstairs. Ice blockage also degrades the device's drainage function, reducing its ability to function properly and its energy efficiency.
[0004] Therefore, a centralized drainage tray is needed to solve the above problems. Utility Model Content

[0036] When manufacturing the centralized drain pan, in order to ensure the beautiful installation of the product and the drainage function of the drain pan, the equipment can be used normally, such as Figure 1-Figure 5 As shown, the utility model provides a centralized drain pan, which includes a drain pan body 1 , a drain pipe 2 , an electric heating element 3 and a mounting fixture 5 .
[0037] The drain pan body 1 has a water collection trough with a drain nozzle in the middle. The bottom of the trough slopes downward toward the nozzle. One end of a drain pipe 2 is fixed to the nozzle. An electric heater 3 is located at the bottom of the trough and extends through the drain pipe 2. A mounting fixture 5 is fixed to the drain pan body 1, allowing the drain pan body 1 to be securely connected to the device 100.
[0038] Because the drain pan body 1 is designed with a drain spout in the middle, the bottom of the drain pan's trough is tilted to converge at a drain outlet, effectively collecting condensed water there. This allows the drain pan to remain level during installation, eliminating the need for tilting to drain water, ensuring a safe and aesthetically pleasing installation. Furthermore, by installing an electric heater 3 at the bottom of the trough, it provides electrical heating, ensuring smooth drainage without ice blockage, thereby maintaining the drain pan's drainage function and enabling normal use of the device 100. Furthermore, because the electric heater 3 is installed within the drain pipe 2, ice blockage within the drain spout and drain pipe 2 can also be prevented.
[0039] In some embodiments, the electric heater 3 is arranged in a bow shape at the bottom of the sump. This effectively covers the bottom of the sump. When ice forms in the sump, the electric heater 3 is controlled to heat the ice, thereby melting it and eliminating the ice in the sump, ensuring that the drain pan can properly drain water.
[0040] In some embodiments, the power cable of the electric heater 3 is passed through the assembly gap reserved between the base of the device 100 and the centralized drain pan, and secured to the wire mesh of the device 100 with a cable tie. The power cable of the electric heater 3 is then secured to the terminal block on the device 100, completing the power connection between the electric heater 3 and the device 100. The assembly gap reserved between the base and the centralized drain pan prevents interference between the device 100 and the centralized drain pan, and also allows the steam generated by the centralized drain pan to be smoothly discharged to the outside when the electric heating function is activated, preventing the steam from corroding the device 100.
[0041] In some embodiments, the bottom of the drain pan body 1 has a drain fixing plate 14, and the drain nozzle is fixedly arranged on the drain fixing plate 14. Specifically, by providing the drain fixing plate 14, it is convenient to install the drain nozzle.
[0042] In some embodiments, the drain pan body 1 includes a blister 11 and a foam fixing plate 13 spaced apart from each other from the inside to the outside, a foam layer 12 is filled between the blister 11 and the foam fixing plate 13, the electric heater 3 is attached to the side of the blister 11 away from the foam fixing plate 13, and the drain fixing plate 14 is embedded in the foam layer 12. The above arrangement facilitates the arrangement of the electric heater 3, and the foam layer 12 can play a role in heat insulation and heat preservation. In this embodiment, the blister 11, the foam layer 12 and the foam fixing plate 13 are formed into an integrated structure by foaming in one step in the foam mold. Since the blister 11 and the foam layer 12 are formed as a whole by high-temperature molding, the blister 11 and the foam layer 12 are stably connected, the blister 11 and the foam layer 12 have good adhesion strength and are not easy to peel off, and the foam layer 12 plays the role of heat preservation, reinforcement and connection. Furthermore, the foam layer 12 and the blister 11 effectively insulate the central drain pan, preventing condensation and ice formation due to temperature differences between the interior and exterior of the central drain pan, which could pose a safety hazard to pedestrians. Furthermore, the blister 11 and the foam fixing plate 13 act as a framework within the central drain pan, ensuring a good drainage angle and smooth drainage.
[0043] In some embodiments, the edge of the blister 11 has a first connecting flange 111, and the foam layer 12 is filled in the first connecting flange 111. By providing the first connecting flange 111, the first connecting flange 111 and the foam layer 12 can be well embedded in the foam layer 12 during the formation, ensuring a reliable connection between the blister 11 and the foam layer 12.
[0044] In some embodiments, the foam fixing plate 13 has a second connecting flange 131 on the side facing the foam layer 12. By providing the second connecting flange 131, the second connecting flange 131 and the foam layer 12 can be well embedded in the foam layer 12 when forming, ensuring a reliable connection between the foam fixing plate 13 and the foam layer 12.
[0045] In some embodiments, the drain fixing plate 14 has a third connecting flange 141. The provision of the third connecting flange 141 allows the third connecting flange 141 to be well embedded in the foam layer 12 during the forming process, ensuring a secure connection between the foam fixing plate 13 and the foam layer 12. The following processes are employed in the manufacture of the drain pan body 1: one involves first making a blister mold, processing the blister component 11, and then placing the blister component 11 into the foam mold in a single forming process; another involves first making a foam mold, processing the foam component, and then using the foam component as the blister mold for a single forming process, i.e., a forming process that avoids the need for a blister mold.
[0046] In some embodiments, the centralized drain pan further includes an annular elastic sealing member 4, which is fixedly mounted on the upper edge of the drain pan body 1. In this embodiment, the annular elastic sealing member 4 is a sponge with a self-adhesive layer. The sponge is attached to the upper edge of the drain pan body 1 to seal the gap between the centralized drain pan and the device 100, preventing external dust from entering the centralized drain pan and forming silt to clog the drain nozzle, thereby causing ice blockage.
[0047] In some embodiments, the mounting fixture 5 includes a connecting mounting plate 52 and an adjusting plate 51. The mounting plate 52 is connected to the drain pan body 1, and the adjusting plate 51 can be connected to the mounting bracket 110 of the device 100. This arrangement eliminates the need for drilling holes in the drain pan body 1 on site. During centralized drainage installation, shock-absorbing rubber pads are placed on the mounting bracket 110, the device 100 is hoisted onto the shock-absorbing rubber pads, and the centralized drain pan is then placed on the bottom of the device 100. Bolts are then threaded through the base mounting holes of the device 100, the shock-absorbing rubber pads, the mounting bracket 110, and the adjusting plate 51, which are then tightened with nuts to secure the centralized drain pan to the device 100. The drain pipe 2 is inserted into the drain nozzle of the centralized drain pan and glued in place, completing the connection between the centralized drain pan and the drain pipe 2. The adjusting plate 51 is bolted to the mounting plate 52 of the centralized drain pan, allowing the installation height of the centralized drain pan to be adjusted based on the thickness of the crossarm of the mounting bracket 110.
[0048] In some embodiments, the electric heating element 3 has a self-limiting temperature controller. By providing the self-limiting temperature controller, the potential safety hazard caused by the dry burning phenomenon inside the centralized drain pan is avoided, and the service life of the electric heating element 3 is increased.
[0049] The control of the electric heating element 3 of this centralized drain pan is as follows:
[0050] Startup conditions (meet any of the following conditions): defrost state; when the unit is running, the ambient temperature is lower than -13°C. Exit conditions (meet any of the following conditions): the compressor is turned off; after exiting defrost, continue to run for a period of time according to the operating time set for the ambient temperature, that is, under the following conditions, the electric heating element 3 is continuously turned on for a period of time. a) When the ambient temperature is lower than -13°C, run according to the actual time of the unit; b) When the ambient temperature is higher than -13°C and lower than -3°C, continue to turn on for 1 minute, and then turn off the electric heating element 3; c) When the ambient temperature is higher than -3°C and lower than 5°C, continue to turn on for 15 minutes, and then turn off the electric heating element 3; d) When the ambient temperature is higher than 5°C, turn off the electric heating element 3 immediately after exiting defrost.
[0051] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
