Description

Technical Field

[0001] This utility model relates to the field of water heater technology, and in particular to a drain nozzle structure and its 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. After a period of use, water may accumulate inside the air source heat pump water heater. To ensure stable operation, drainage is necessary. Existing technologies use multiple drainage holes on the water inlet plate to ensure smooth drainage. Others use centralized drainage. In centralized drainage units, the drain nozzle is directly snapped into a circular drain port on the water inlet plate, using the deformation of the snap to secure the drain nozzle. This installation process is relatively difficult and extremely inconvenient. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a drain nozzle structure and its air source heat pump water heater, which solves the problem that fixing the drain nozzle to the water receiving base with clips is extremely inconvenient during installation.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The mounting ear is located at the upper end of the water inlet pipe body. The cross-section of the mounting ear is fan-shaped, and a hanging groove is provided on the outer side of the upper end of the mounting ear.

[0007] The upper outer periphery of the water receiving pipe is sealed with a ring plate, and the upper surface of the ring plate is located above the upper opening of the water receiving pipe. The mounting ear is located inside the ring plate. The overflow wall is funnel-shaped, and the lower end of the overflow wall is connected to the outer periphery of the ring plate.

[0008] Preferably, there are two mounting ears.

[0009] Preferably, the two mounting ears are symmetrically arranged on both sides of the water inlet pipe.

[0010] Preferably, the outer surface of the water receiving pipe is provided with a toothed pattern, and the toothed pattern is located at the lower end of the water receiving pipe.

[0011] Preferably, the top of the mounting ear is configured as an outwardly inclined slope.

[0012] An air source heat pump water heater includes a drain nozzle structure as described in any one of the above, and also includes a main body and a water receiving base plate. The water receiving base plate is disposed at the bottom of the main body, and a drain hole is provided on the water receiving base plate. The drain hole is located at the lowest point of the water receiving base plate, and the mounting ear is engaged in the drain hole.

[0013] Preferably, the diameter of the drain hole is smaller than the diameter of the circle containing the outer edge of the vertical projection of the mounting ear and larger than the diameter of the circle containing the vertical projection of the bottom of the mounting groove, and the inner wall of the drain hole is provided with a groove that matches the mounting ear.

[0014] Preferably, the water receiving base plate is provided with a water guiding surface, the drain hole is provided on the water guiding surface, and the upper surface of the water guiding surface is provided with a slope inclined towards the drain hole.

[0015] Preferably, the water guiding surface is configured as an L-shape.

[0029] To make the technical means, creative features, objectives and effects of this utility model clearer and easier to understand, the technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0030] Please see Figures 1 to 8 As shown, a drain nozzle structure includes: a water inlet pipe body 1, a mounting ear 2, and an overflow prevention wall 3. The mounting ear 2 is located at the upper end of the water inlet pipe body 1, and the cross-section of the mounting ear 2 is fan-shaped. A mounting groove 4 is provided on the outer side of the upper end of the mounting ear 2. An annular plate 11 is sealed to the outer periphery of the upper end of the water inlet pipe body 1, and the upper surface of the annular plate 11 is located above the opening at the upper end of the water inlet pipe body 1. The mounting ear 2 is located inside the annular plate 11. The overflow prevention wall 3 is funnel-shaped, and its lower end is connected to the outer periphery of the annular plate 11. The connection between the lower end of the overflow prevention wall 3 and the outer periphery of the annular plate 11 forms a water-receiving structure to prevent overflow.

[0031] Furthermore, such as Figure 2 , Figure 3 and Figure 5 As shown, to improve stability, two mounting ears 2 are provided. Furthermore, the two mounting ears 2 are symmetrically arranged on both sides of the water inlet pipe body 1.

[0032] Furthermore, such as Figure 3 and Figure 5 As shown, the outer surface of the water inlet pipe body 1 is provided with a toothed pattern 12, and the toothed pattern 12 is located at the lower end of the water inlet pipe body 1. The toothed pattern 12 is provided to facilitate the user's connection and bundling of the water inlet pipe, and also serves as an anti-slip function.

[0033] Furthermore, such as Figure 3 and Figure 5 As shown, in order to facilitate quick and accurate insertion of the mounting ear 2 into the drain hole 7, the top of the mounting ear 2 is set as an outward inclined surface.

[0034] like Figure 1As shown, an air source heat pump water heater includes a drain nozzle structure as described in any one of the above claims, and further includes a main body 5 and a water receiving base plate 6. The water receiving base plate 6 is disposed at the bottom of the main body 5, and a drain hole 7 is provided on the water receiving base plate 6. The drain hole 7 is located at the lowest point of the water receiving base plate 6, and the mounting ear 2 is snapped into the drain hole 7. The drain hole 7 is located at the lowest point of the water receiving base plate 6, so that water on the water receiving base plate 6 can be discharged through the drain hole 7.

[0035] Furthermore, such as Figures 2 to 8 As shown, the diameter of the drain hole 7 is smaller than the diameter of the circle containing the outer edge of the vertical projection of the mounting ear 2 and larger than the diameter of the circle containing the vertical projection of the bottom of the mounting groove 4. The inner wall of the drain hole 7 is provided with a groove 71 that fits the mounting ear 2. When the mounting ear 2 extends into the drain hole 7, it aligns with the groove 71 of the drain hole 7, i.e. Figure 7 As shown; when the water receiving base plate 6 is at the same horizontal position as the mounting groove 4, rotate the water receiving pipe body 1, and the mounting ear 2 rotates, so that the water receiving base plate 6 is inserted into the two mounting grooves 4. At this time, the mounting ear 2 is misaligned with the groove 71, that is, as shown. Figure 8 As shown.

[0036] Furthermore, such as Figure 3 and Figure 4 As shown, a water-guiding surface 8 is provided on the water-receiving base plate 6, and a drain hole 7 is provided on the water-guiding surface 8. The upper surface of the water-guiding surface 8 is set as a sloped surface inclined towards the drain hole 7. The water-guiding surface 8 with an inclined slope is provided so that water can flow smoothly into the drain hole 7, making it easy to collect and discharge.

[0037] Furthermore, such as Figure 4 As shown, the water guiding surface 8 is L-shaped. An evaporator placement platform 81 is provided on the water guiding surface 8. An evaporator is provided inside the air source heat pump water heater, which is existing technology and will not be elaborated on further; when setting the evaporator placement platform 81, it is necessary to ensure that the evaporator is placed stably to avoid tipping over.

[0038] In use, the lower end of the water inlet pipe 1 is connected to the user's drain pipe. The mounting ear 2 on the water inlet pipe 1 extends into the drain hole 7 on the water guide surface 8, simultaneously aligning the groove 71 with the mounting ear 2. When the water inlet base plate 6 is at the same horizontal position as the mounting groove 4, rotating the water inlet pipe 1 causes the mounting ear 2 to rotate, causing the water inlet base plate 6 to engage with the two mounting grooves 4. At this point, the mounting ear 2 and the groove 71 are misaligned, and the upper end of the overflow wall 3 abuts against the bottom of the water inlet base plate 6 to prevent overflow. The groove 71, located within the drain hole 7 on the water inlet base plate 6, facilitates easy installation. The water guide surface 8 on the water inlet base plate 6 is sloped to prevent water from becoming sticky, thus improving drainage smoothness.

[0039] 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.
