Description

Technical Field

[0001] This utility model relates to the field of air source heat pump technology, specifically to a defrosting and drainage device for an air source heat pump hot air blower. Background Technology

[0002] An air source heat pump hot air blower is a heating device based on air source heat pump technology, mainly used for heating in winter. Its core principle is to absorb heat from the air and transfer it indoors through heat pump circulation to achieve efficient heating. In low-temperature environments, the evaporator surface of the heat pump is prone to frost formation, affecting heating efficiency, so defrosting is required.

[0003] In existing technologies, defrosting is typically achieved by extracting high-temperature exhaust gas from the compressor to melt the evaporator frost, or by switching a four-way valve to utilize the heat from the indoor heat exchanger. The defrosted water then flows out through the drain hole via a water guide. However, in actual use, defrost water tends to accumulate in the area below the air source heat pump after being drained. This accumulated defrost water is prone to freezing, which can easily cause pedestrians to slip and fall. Furthermore, the defrost water can form icicles that can clog the drain hole, causing the defrost water to flow back into the equipment and resulting in secondary freezing of the evaporator, thus affecting the heating effect. Therefore, it is necessary to develop an improved defrost and drainage device for air source heat pump hot air blowers to solve the above problems. Utility Model Content

[0023] Please see Figure 1-3This utility model provides a technical solution: a defrosting and drainage device for an air source heat pump hot air blower, including a support frame 1 and a V-shaped water receiving tray 2. An installation plate 3 is fixedly installed on the top of the support frame 1. An air source heat pump 4 is fixedly installed on the top of the installation plate 3 by bolts. Several through holes are equally spaced inside the installation plate 3 to facilitate the installation of the support feet of the air source heat pump 4 on the top of the installation plate 3 by bolts and nuts. It is particularly noteworthy that multiple drainage holes are opened at the bottom of the air source heat pump 4. After the defrosting water flows out through the drainage holes, it falls into the interior of the V-shaped water receiving tray 2. A drainage mechanism 5 is provided on the outside of the V-shaped water receiving tray 2, and a limit mechanism 6 is provided on the outside of the drainage mechanism 5.

[0024] Furthermore, the drainage mechanism 5 includes a water outlet pipe 501, which is fixedly installed at the right end of the V-shaped water receiving tray 2. The right end of the water outlet pipe 501 is connected to an external water pipe via a clamp. The other end of the external water pipe is placed at a suitable drainage point to facilitate the discharge of defrost water. A handle 502 is fixedly installed at the left end of the V-shaped water receiving tray 2. A heating wire 503 is fixedly installed inside the V-shaped water receiving tray 2. The heating wire 503 is connected to an indoor leakage current protector via a wire to supply power to the heating wire 503. There are two heating wires 503, which are symmetrically installed on the inner inclined surface of the V-shaped water receiving tray 2 to prevent defrost water from freezing on the surface of the V-shaped water receiving tray 2. Frost water can easily form ice columns, causing blockage of the drain hole of the air source heat pump 4. A heat insulation cloth 504 is fixedly installed at the bottom of the V-shaped water receiving tray 2, which makes it difficult for heat to be lost from the bottom of the V-shaped water receiving tray 2, thus increasing the heating efficiency. A T-shaped block 505 is fixedly installed on the outside of the V-shaped water receiving tray 2, and a positioning seat 506 is fixedly installed on the inner wall of the support frame 1. Two sets of T-shaped blocks 505 and positioning seats 506 are respectively provided. The two sets of T-shaped blocks 505 are symmetrically installed on the outside of the V-shaped water receiving tray 2, and the two sets of positioning seats 506 are symmetrically installed on the inner wall of the support frame 1. The positioning seats 506 are inclined to facilitate the positioning of the V-shaped water receiving tray 2, so that the V-shaped water receiving tray 2 can be kept in an inclined state, ensuring the stability of the V-shaped water receiving tray 2.

[0025] Furthermore, a groove is provided inside the positioning seat 506 at the position corresponding to the T-shaped block 505, and the T-shaped block 505 is slidably installed in the groove, which facilitates the quick positioning of the T-shaped block 505, makes it easy for the V-shaped water receiving tray 2 to remain in an inclined state, increases the flow rate of defrosting water, and facilitates the subsequent discharge of defrosting water.

[0026] Please see Figure 4Furthermore, in conjunction with Embodiment 1, the limiting mechanism 6 includes a stud 601, which is rotatably mounted on the outside of the positioning seat 506. A handwheel 602 is fixedly mounted on the end of the stud 601 away from the positioning seat 506. The surface of the handwheel 602 is provided with anti-slip texture to increase the friction between the hand and the handwheel 602, facilitating rotation of the handwheel 602. A connecting plate 603 is threaded onto the outside of the stud 601. A guide rod 604 is fixedly mounted on the outside of the positioning seat 506, and a guide rod 604 is fixedly mounted on the inside of the connecting plate 603. Equipped with a plunger 605, the plunger 605 is used to limit the T-shaped block 505, thereby ensuring the stability of the V-shaped water receiving tray 2 and preventing displacement of the V-shaped water receiving tray 2. By rotating the handwheel 602, the stud 601 can be rotated. With the cooperation of the guide rod 604, the connecting plate 603 can be moved, so that the plunger 605 can be moved away from the T-shaped block 505, which facilitates the quick release of the limiting work on the T-shaped block 505, and makes it convenient to disassemble the V-shaped water receiving tray 2 and clean it.

[0027] Furthermore, a through hole is provided inside the connecting plate 603 at the position corresponding to the guide rod 604, and the guide rod 604 is slidably installed in the through hole, which facilitates the guidance of the connecting plate 603 during the movement, making the movement of the connecting plate 603 more stable.

[0028] Furthermore, a through hole is provided inside the positioning seat 506 at the corresponding position of the insertion post 605, and the insertion post 605 is slidably installed in the through hole. The through hole is connected to the T-shaped sliding groove opened inside the positioning seat 506, which facilitates the movement of the insertion post 605 inside the positioning seat 506 and facilitates the disassembly and assembly of the V-shaped water receiving tray 2.

[0029] Furthermore, a groove is provided inside the T-shaped block 505 at the position corresponding to the insertion post 605, and the insertion post 605 is inserted into the groove. The depth of the groove is less than the length of the stud 601 to ensure that the insertion post 605 can be disengaged from the groove, so as to facilitate the quick release of the limiting work on the T-shaped block 505.

[0030] In actual operation, when this device is used, the V-shaped water receiving tray 2 is positioned by sliding the T-shaped block 505 into the groove inside the positioning seat 506, keeping the V-shaped water receiving tray 2 tilted. By rotating the handwheel 602, the connecting plate 603 with the external thread of the stud 601 is moved, so that the insert 605 is inserted into the groove inside the T-shaped block 505, completing the limiting work of the V-shaped water receiving tray 2. By connecting the external water pipe to the outlet pipe 501, and placing the other end of the external water pipe at a suitable discharge point, the air source heat pump 4 is installed on the top of the mounting plate 3 by bolts. During defrosting, defrosting water flows through the water guide groove and out of the drain hole, so that the defrosting water falls into the interior of the V-shaped water receiving tray 2, thereby allowing the defrosting water to flow out from the outlet pipe 501. With the cooperation of the external water pipe, the defrosting water is guided to the discharge point. With the cooperation of the heating wire 503, the defrosting water is prevented from freezing on the surface of the V-shaped water receiving tray 2.
