Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of low-temperature air source heat pumps, and particularly relates to a drainage structure of a low-temperature air source heat pump. Background Art
[0002] As shown in the attached Figure 1 In the figure, for the condensate drainage mode of the traditional heat pump unit, a water pipe 100 is used to connect from the water collecting tray to the bottom drainage + chassis defrosting heating belt mode. However, when applied in an outdoor ambient temperature below -20°C, due to extremely cold and foggy weather, the condensate generated during the defrosting of the unit will freeze before flowing to the drainage outlet. After the unit defrosts multiple times, the water collecting trough and drainage outlet of the water collecting tray will be blocked by ice, resulting in the inability to drain the condensate generated during the defrosting of the unit, and thus the ice climbing phenomenon will occur. First, it causes the evaporator to freeze and the energy efficiency of the unit to deteriorate; second, it causes ice climbing at the bottom of the motor bracket, and the wind blade touches the ice and is damaged, seriously affecting the normal use of the wind blade.

[0031] Example 1
[0032] This embodiment provides a drainage structure for a low-temperature air source heat pump. As shown in the attached Figure 2-5 figure, it includes:
[0033] A water accumulation tray 11, which is provided with a flat area 111, a water collection area 112, an inclined part 113 and a drain port 114. The inclined part 113 connects the flat area 111 and the water collection area 112. Here, the flat area 111 is located below the condensed water generated during the defrosting of the unit, forming a downward connection effect. The water accumulation tray 11 is specifically located below the fan 12. The size of the flat area 111 occupying the entire water accumulation tray 11 can be adjusted according to actual needs. The inclined part 113 connects the flat area 111 and the water collection area 112, forming a height difference effect, that is, forming a drainage effect to guide the condensed water to flow towards the water collection area 112. Here, the inclined part 113 can be a plane or an arc surface. In addition, the inclined part 113 can be gradually reduced to form a flowing effect, that is, the inclined part 113 is a stepped structure. The number of water collection areas 112 can be one, two, three, or four. In this embodiment, taking two water collection areas 112 as an example, the two water collection areas 112 are located at the corner positions of the water accumulation tray 11. In this embodiment, the structures of the two water collection areas 112 are similar, so the heating belt 13 in one of the water collection areas 112 is not shown in the attached figure. The bottom surface of the flat area 111 is higher than the top surface of the water collection area 112, that is, a height difference is formed. The drain port 114 is communicated with the water collection area 112, and the drain port 114 opens towards the horizontal direction. Here, the horizontal direction specifically means that the water accumulation tray 11 is located on a horizontal plane, and the horizontal direction is the front side, rear side, left side, and right side of the water accumulation tray 11. Those skilled in the art can adjust the direction of the drain port 114 according to actual needs. A heating belt 13 is fixed on the water collection area 112, and the heating belt 13 can be electric heating or other heating methods. With this structural setting, the flat area 111 is located below the condensed water generated during the defrosting of the unit, forming a downward connection effect. Due to the settings of the flat area 111, the water collection area 112, and the inclined part 113, a height difference is formed, and the condensed water will flow to the water collection area 112 through the inclined part 113, forming a water collection effect, and finally being directly discharged through the drain port 114; compared with the prior art, this structure reduces the movement length of the condensed water and avoids the freezing of the condensed water. The setting of the inclined part 113 can deepen the water collection area 112 and avoid water accumulation in the flat area 111. The installation of the heating belt 13 in the water collection area 112 avoids the wind field taking away heat and being unable to completely melt the ice cubes.
[0034] Specifically, the heating strip 13 extends to the planar region 111. By adopting an extended setting, the heating strip 13 can increase the heating area and improve the ice melting effect. In addition, there can be multiple heating strips 13, that is, the heating strip 13 is fixed to the planar region 111, and the heating strip 13 is also fixed to the water collection region 112, and the heating strips 13 of the two are independently arranged.
[0035] Specifically, as shown in the attached Figure 2-5 figure, the bottom surface of the water collection region 112 is planar or inclined. The planar setting makes the processing more convenient, and the inclined setting forms a certain guiding effect, enabling the condensed water to flow in one direction. Those skilled in the art can adjust the relevant structure of the water collection region 112 according to actual needs.
[0036] Specifically, the drain port 114 communicates with the lowest point of the water collection region 112. Such a structural setting can better achieve the drainage effect.
[0037] Specifically, as shown in the attached Figure 2-5 figure, the water collecting tray 11 is provided with a drain post 115, the drain port 114 is arranged on the drain post 115, and the drain post 115 extends outward along the horizontal direction. The setting of the drain post 115 forms an effect of lengthening the drainage, so that the drained water will not affect the lower part of the entire device. The length of the drain post 115 here can be adjusted according to actual needs.
[0038] Specifically, the drain post 115 is arranged on the rear side surface of the water collecting tray 11. The drain post 115 on the rear side surface has a hidden effect, improving the aesthetics. Moreover, with the drain post 115 on the rear side surface, no water pipe needs to be connected, saving materials. It should be noted that the rear side surface is the back of the entire device.
[0039] Specifically, the drain post 115 is provided with a joint structure. The setting of the joint structure facilitates the connection and fixation of the water pipe to the drain post 115. In addition, the drain post 115 can also drain water directly without connecting a water pipe.
[0040] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
