Description

Technical Field

[0001] This utility model relates to the technical field of emission guidance devices, specifically an air source heat pump hot air blower defrost water emission guidance device. Background Technology

[0002] The defrost water drainage guide device for air source heat pump hot air blowers is a system component used to handle the melted defrost water generated during the defrosting process. Its main function is to ensure that the defrost water is effectively collected, guided, and safely discharged, preventing water accumulation, freezing, equipment corrosion, or impact on the surrounding environment. It mainly consists of an inclined water receiving tray (collection tray) and a drain pipe.

[0003] In existing technology, when a heat pump enters defrost mode, the frost layer melts into water, which drips into a drip tray. The water is then collected in the drip tray and directed to a drain pipe, which discharges the water away from the equipment to prevent secondary freezing or water accumulation. In cold regions, to prevent the pipes from freezing during drainage, insulation cotton is usually wrapped around the outside of the drain pipe and secured with cable ties. However, in actual use, ordinary plastic cable ties are prone to aging, brittleness, or even breakage in cold, ultraviolet-exposed, or humid environments, causing the insulation cotton to fall off. At the same time, the cable ties only rely on circumferential pressure to secure the insulation cotton. At pipe bends, the insulation layer may shift, leading to cold leakage. Therefore, an improved defrost water drainage guide device for air source heat pump hot air blowers is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a defrosting water discharge guiding device for an air source heat pump hot air blower to solve the problems mentioned in the background art.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0017] Please see Figure 1-5 This utility model provides a technical solution: a defrosting water discharge guiding device for an air source heat pump hot air blower, including a water receiving tray 1, a bottom hopper 3 fixedly installed at the bottom of the water receiving tray 1, a connecting pipe head 4 fixedly installed at the bottom of the bottom hopper 3, and a guiding and heat preservation mechanism 2 provided at the bottom of the connecting pipe head 4.

[0018] Furthermore, the guiding and insulation mechanism 2 includes a docking cover 21, which is threaded onto the outside of the connecting pipe head 4. A drain hose 22 is fixedly installed at the bottom of the docking cover 21. An insulation layer 23 is provided on the outside of the drain hose 22. A Velcro loop side 24 and a Velcro bar side 25 are fixedly installed on the outside of the insulation layer 23. An elastic braided mesh sleeve 26 is provided on the outside of the insulation layer 23. A stainless steel clamp 27 is provided on the outside of the elastic braided mesh sleeve 26. A rubber liner 28 is fixedly installed inside the stainless steel clamp 27. A bolt and nut assembly 29 is provided inside the stainless steel clamp 27. Through the provided guiding and insulation mechanism 2, the drain hose 22 can be used to guide the discharge of frost water. At the same time, it can effectively fix the insulation layer 23, preventing the insulation layer 23 from falling off. It can also prevent the insulation layer 23 from leaking cold due to gaps when the drain hose 22 is bent.

[0019] Furthermore, the stainless steel clamp 27 has a hole inside, and the bolt in the bolt and nut assembly 29 is slidably installed inside the hole inside the stainless steel clamp 27. By using the bolt sliding inside the stainless steel clamp 27, the two stainless steel clamps 27 can be fitted together and then fixed to the outside of the elastic woven mesh sleeve 26, which can limit and fix the port of the insulation cotton layer 23 and prevent the insulation cotton layer 23 from sliding.

[0020] Furthermore, the water tray 1 is made of corrosion-resistant aluminum alloy by stamping and is coated with epoxy resin with a thickness of 0.8-1.2mm. The edge is provided with 10-15mm flanged reinforcing ribs, which can enhance the overall structure of the water tray 1 and prevent the water tray 1 from deforming.

[0021] Furthermore, the drain hose 22 is made of low-temperature resistant rubber hose with an inner diameter of φ40mm, a wall thickness of 3mm, and a bending radius of ≥100mm. By utilizing the low-temperature resistance of the drain hose 22 itself, the lifespan of the drain hose 22 in low-temperature environments can be increased. At the same time, with the cooperation of the insulation cotton layer 23, it can effectively insulate the guided frost water.

[0022] Furthermore, the insulation layer 23 is made of closed-cell rubber and plastic foam insulation cotton with a thickness of 20-25mm. It is longitudinally slit to wrap around the outer wall of the drain hose 22. The inner and outer surfaces of the insulation layer 23 are covered with aluminum foil to enhance waterproofness and reflect radiant heat. The longitudinal slit is designed to cover the outside of the drain hose 22.

[0023] Furthermore, the elastic woven mesh cover 26 is made of a blend of polyester fiber and spandex, with a mesh size of 3×3mm. It is placed outside the insulation cotton layer 23, and the elastic woven mesh cover 26 wraps the insulation cotton, using elastic shrinkage force to evenly compress the insulation layer.

[0024] In actual operation, when this device is used, first rotate the docking cover 21 outside the connecting pipe head 4 to install the docking cover 21 and the connecting pipe head 4. At this time, the drainage hose 22 is fixed. Through the longitudinal gap of the insulation cotton layer 23, the insulation cotton layer 23 is wrapped around the outside of the drainage hose 22. At this time, the loop side 24 and the loop side 25 of the Velcro are attached to each other to fix the insulation cotton layer 23. After the insulation cotton layer 23 is fixed, the elastic braided mesh sleeve 26 is put on the outside of the insulation cotton layer 23 so that the elastic braided mesh sleeve 26 completely covers the insulation cotton layer 23. Then, the stainless steel clamp 27 is clamped at both ends of the insulation cotton layer 23, and the bolt and nut combination 29 is tightened to complete the insulation installation of the drainage hose 22.
