Description

Technical Field

[0001] This utility model relates to the field of heat pump technology, and in particular to a drainage structure and an air source heat pump water heater. Background Technology

[0002] Air source heat pump water heaters are energy-saving and environmentally friendly hot water supply devices that can replace boilers and are not limited by resources. They use green, pollution-free refrigerant to absorb heat from the air, and through the work of a compressor, produce domestic hot water above 50 degrees Celsius. They are suitable for indoor swimming pools, hotels, villas, hair salons, bathhouses, factories, schools, farms, and other places requiring hot water supply. Centralized drainage is particularly important. Current technology uses a series of drain holes below the water receiving plate, which is not convenient for centralized drainage. To achieve centralized drainage, a large water receiving tray is usually installed below the unit, which undoubtedly increases costs. Utility Model Content

[0025] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0026] See Figures 1 to 4 This utility model provides a drainage structure, including:

[0027] Water receiving tray 2 is equipped with multiple water inlets 21;

[0028] Multiple water inlet pipes 3 are connected one-to-one to multiple water inlet ports 21 to form multiple water inlet paths that are independently set up.

[0029] The drain pipe 4 is connected in series with multiple water inlet pipes 3 so that condensate water from multiple water inlet paths converges into the drain pipe 4 and is discharged through the drain pipe 4.

[0030] In this embodiment, the water receiving tray 2 is provided with two water inlets 21, which can simultaneously receive condensate. Each water inlet 21 corresponds to an independent water receiving pipe 3, forming a drainage channel that is isolated from each other, avoiding overflow caused by excessive condensate, or backflow or blockage caused by pressure difference, thereby improving drainage efficiency and stability. The two water receiving pipes 3 are finally connected in series to the same drain pipe 4, which concentrates the dispersed condensate for discharge, simplifies the pipe layout, and adapts to the split structure of the heat pump unit 1 with multiple evaporators.

[0031] At least one of the water inlet pipes 3 is connected to the drain pipe 4 via a bend section 5.

[0032] In this embodiment, a water inlet pipe 3 is connected to another water inlet pipe 3 through a bend section 5. The bend section 5 can be a 90° bend, which can alleviate the impact of water flow and allow condensate to flow into the drain pipe 4 more smoothly, reducing turbulence and air blockage.

[0033] At least one of the water inlet pipes 3 is connected to the drain pipe 4 via a connecting pipe 6. Furthermore, both ends of the connecting pipe 6 are provided with bends 5 for connecting the water inlet pipe 3 and the drain pipe 4, respectively.

[0034] In this embodiment, the connecting pipe 6 provides more spatial adaptability for the drainage structure, especially in cases where the installation location is complex or the installation space is limited. Another water inlet pipe 3 is connected to the drain pipe 4 through the connecting pipe 6. A bend section 5 is provided at both ends of the connecting pipe 6 for connection. One end of the bend section is connected to the water inlet pipe 3 and the other end is connected to the drain pipe 4, which is used to adjust the spatial direction between the water inlet pipe 3 and the drain pipe 4.

[0035] The two bends 5 have opposite opening directions, which are used to form a clearance 7 with the connecting pipe 6.

[0036] In this embodiment, one bend section 5 is connected to the first end of the connecting pipe 6, and the other bend section 5 is connected to the end of the connecting pipe. The opening directions of the two bend sections 5 are opposite, which is used to form an S-shaped structure to avoid the internal pipeline of the unit 1.

[0037] The water receiving tray 2 is equipped with multiple clamps 8 for fixing the water receiving pipe 3 and the drain pipe 4.

[0038] In this embodiment, the water receiving tray 2 is provided with multiple clamps 8 for fixing the water receiving pipe 3 and the drain pipe 4. Anti-vibration pads can be set on the clamps 8 to prevent the drain pipe 4 from breaking due to vibration during the transportation of the unit 1.

[0039] The water receiving tray 2 has a funnel-shaped cross-section; the water inlet 21 is located at the lowest point of the water receiving tray 2.

[0040] In this embodiment, the water receiving tray 2 is composed of two separate water receiving trays 2. A water inlet 21 is provided at the lowest point of the center of each water receiving tray 2, and the cross-section of the two water receiving trays 2 is funnel-shaped. The water inlet 21 is located at the lowest point of the bottom of the water receiving tray 2 to ensure that the condensate can be discharged smoothly, improve the overall drainage speed, and prevent water accumulation.

[0041] The water receiving tray 2 is provided with multiple first mounting points 9 and multiple second mounting points 10, with the first mounting points 9 and the second mounting points 10 being arranged perpendicularly.

[0042] In this embodiment, multiple first mounting points 9 are slots arranged vertically on the water receiving tray 2, and multiple second mounting points 10 are bolt holes arranged front-back on the water receiving tray 2. During installation, the slots are engaged with the air source heat pump water heater, and then bolts are used to fix the water heater. The two vertically arranged mounting points can effectively share the load and prevent loosening and falling off.

[0043] This embodiment also provides an air source heat pump water heater, including the drainage structure described above. The specific structure of the air source heat pump water heater is the same as described in the above embodiment. Since this air source heat pump water heater adopts all the technical solutions of the above embodiment, it has at least all the beneficial effects brought about by the technical solutions of the above embodiment, which will not be described in detail here.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
