Description

Technical Field

[0001] The present invention relates to the field of air heat source pumps, and in particular to an intelligent defrosting air source heat pump. Background Art

[0002] An air heat source pump is a device that uses the heat in the air to provide heating, hot water or cooling. The air source heat pump absorbs the heat in the air, converts it into high-temperature heat energy after compression by a compressor, and then transfers the heat to water or other media through a heat exchanger, thereby achieving heating or hot water supply.

[0003] Authorized patent number: CN 117588872 B records "an intelligent defrosting air source heat pump". By setting a vibration generator, an ultrasonic generator, a vibration plate and a mounting plate, the frost attached to the fins is split and separated by ultrasound and then vibrated off the fins by relatively violent mechanical vibration. After that, the detached frost leaves the gap between the fins under the blowing of the airflow, ensuring a good defrosting effect. In addition, by setting guide lines and guide grooves, under the action of the airflow, it is not easy for water droplets to adhere to the fins and drain pipes with a hydrophobic layer on the surface, and the water droplets are relatively fully detached. Moreover, under the action of the guide lines and guide grooves, the water droplets attached to the fin surface are further promoted to fall off, thereby improving the defrosting effect.

[0004] However, there are still the following defects and shortcomings in the application process: For the frost that is broken by the water droplets on the fins and row tubes, if the particle size of the broken frost is relatively large, so that the gravity force on it is greater than the wind force, it will fall into the shell and finally melt into water, which can easily seep into the equipment; for the water droplets on the fins and row tubes, there is also the possibility of falling into the shell, which can easily cause damage to the equipment itself.

[0005] Therefore, it is necessary to provide a new intelligent defrosting air source heat pump to solve the above technical problems. Summary of the invention

[0019] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0021] An embodiment of the present invention provides an intelligent defrosting air source heat pump, the intelligent defrosting air source heat pump comprising a housing 1, a discharge member 4, a medium driving mechanism 5, a vibration driving mechanism 6, and an elastic support member 3; For case 1; See also Figures 1 to 3 A fan 11 is installed inside the casing 1, and a mounting frame 12 is also installed, on which fins 13, a row of pipes 14 and an ultrasonic generating device 2 are fixed.

[0022] It should be noted that the fan 11, fins 13 and exhaust pipes 14 inside the casing 1 are all existing technical structures in air source heat pumps and will not be described in detail here. The ultrasonic generating device 2 is described in detail in the authorized patent number "CN 117588872 B" and will not be described in detail here.

[0023] For the drain 4; See also Figure 5 and Figure 6The drainage member 4 includes a bracket 41, which is symmetrically arranged in two groups, both of which are fixed to the inside of the housing 1 and located below the mounting frame 12 by screws. A drainage pipe 42 is fixed on one of the brackets 41, and a water receiving bucket 43 and a discharge pipe 44 are fixed on the discharge pipe 42. The upper end of the water receiving bucket 43 has an opening, and the inner bottom is an inclined surface, and a connecting pipe is integrally connected at the lowest point of the inclined surface. The connecting pipe is screwed to the outer wall of the drainage pipe 42 and close to the discharge pipe 44; A bracket 45 is bolted to the other tripod 41 . The bracket 45 extends to below the drainage pipe 42 and is bolted to a first fixing frame 46 for supporting the drainage pipe 42 . A second fixing frame 47 for supporting the docking bucket 43 is also bolted to the first fixing frame 46 .

[0024] It should be noted that: for the drainage member 4, its water receiving bucket 43, drainage pipe 42 and discharge pipe 44 form a pipeline structure for collecting, delivering and draining water. The upper end of the water receiving bucket 43 has an opening, and it is arranged below the fin 13 and the discharge pipe 14. Therefore, water drops or frost dripping from the fin 13 and the discharge pipe 14 can fall into the water receiving bucket 43, enter the drainage pipe 42, and finally be discharged from the discharge pipe 44, thereby preventing water stains from entering the device, and having a good protective effect on the device itself; Only one end of the drain pipe 42 is fixed to the tripod 41. To ensure its stability, a bracket 45 is installed on the other tripod 41, and a first fixing frame 46 is installed on the bracket 45. The first fixing frame 46 is sleeved and fixed on the drain pipe 42, so as to support the drain pipe 42. At the same time, a second fixing frame 47 is also installed on the first fixing frame 46. The second fixing frame 47 is fixed to the water receiving bucket 43, so as to support the water receiving bucket 43 and further improve the stability of the pipeline system.

[0025] For the medium driving mechanism 5; See also Figure 6 and Figure 7 The medium driving mechanism 5 includes a rotating shaft 51, which concentrically penetrates the discharge pipe 42 and is rotatably connected thereto. The rotating shaft 51 is also rotatably connected to both legs 41. A spiral plate 52 located inside the discharge pipe 42 and used to promote the directional flow of the liquid is welded to the circumferential outer wall of the rotating shaft 51; A plurality of equally spaced ring frames 53 are sleeved and fixed on the rotating shaft 51 and located outside the discharge pipe 42 . A plurality of annularly distributed connecting rods 54 are welded and fixed to the circumferential outer wall of the ring frames 53 . A hemispherical shell 55 is fixed to the other end of the connecting rod 54 . The shell 55 is located at the downwind position of the fan 11 .

[0026] It should be noted that: the medium driving mechanism 5 is located at the downwind position of the fan 11. When the fan 11 is running, the airflow will also act on the shell 55, and the shell 55 is hemispherical, that is, one side is an outer convex surface and the other side is an inner concave surface. Therefore, when the airflow acts on the shell 55, a pressure difference will be formed on the two sides. The pressure difference is used to drive the rotating shaft 51 to rotate. The rotating shaft 51 has a spiral plate 52, and the spiral plate 52 is located inside the drainage pipe 42. Therefore, during the rotation process, it can promote the directional flow of the medium inside the drainage pipe 42 to facilitate the discharge of collected water. Therefore, for the medium driving mechanism 5, it does not need a targeted driving source during its operation, which has the effect of energy saving; In addition, during the rotation of the rotating shaft 51 and the spiral plate 52, a certain amount of heat will be generated due to friction. The heat is concentrated inside the drainage pipe 42, which can melt the frost that falls into the drainage pipe 42. After melting, it is more convenient to discharge it, and ice formation inside the drainage pipe 42 can also be avoided. It should also be noted that the connection position between the water receiving bucket 43 and the drainage pipe 42 is closer to the discharge pipe 44, so the collected water and frost can enter the discharge pipe 44 and be discharged more quickly; at the same time, this setting can also shorten the length of the spiral plate 52, so when the rotating shaft 51 rotates, the obstruction will be smaller and its own rotation speed will be relatively higher.

[0027] For the vibration drive mechanism 6; See also Figure 8 The vibration driving mechanism 6 includes a driving pulley 61, which is keyed to the rotating shaft 51, and is also rotatably connected to a positioning shaft 62 on the mounting frame 12. A driven pulley 63 and an eccentric counterweight 64 are keyed to the positioning shaft 62. The driving pulley 63 and the driven pulley 63 are connected by a transmission belt 65, which is used to drive the positioning shaft 62 and the eccentric counterweight 64 to rotate in a circle.

[0028] It should be noted that: in the vibration drive mechanism 6, the driving pulley 61 is installed on the rotating shaft 51, and when the rotating shaft 51 rotates, it can directly drive the driving pulley 61 to rotate; the positioning shaft 62 rotates on the mounting frame 12, and the driven pulley 61 and the eccentric counterweight 64 are fixed on the positioning shaft 62. Therefore, when the driving pulley 61 rotates, the positioning shaft 62 can be driven to rotate at high speed through the transmission belt 65, and then the eccentric counterweight 64 can be driven to rotate together. The eccentric counterweight 64 will generate centrifugal force when rotating. Under the action of this centrifugal force, the mounting frame 12 and the fins 13 and the row pipes 14 installed therein will vibrate, which is used to replace the vibration generator, so that it can cooperate with the ultrasonic generating device 2 to break the frost on the fins 13 and the row pipes 14.

[0029] For the elastic support member 3; See also Figure 3 and Figure 4 , elastic support members 3 are installed at both upper and lower ends of the mounting frame 12, the elastic support member 3 at the upper end is also fixed to the inner wall of the housing 1 through a right-angle frame, and the elastic support member 3 at the lower end is also fixed to the tripod 41; The elastic support member 3 includes two baffles 31 distributed up and down, with a spring 33 between the two baffles 31, and a slidingly connected threaded rod 32 passing through the two baffles 31. One end of the threaded rod 32 also passes through the mounting frame 12 and is fixed by a nut 34 and a gasket 35; the other end of the threaded rod 32 passes through the right-angle frame / tripod 41 and is fixed by a nut 34 and a gasket 35.

[0030] It should be noted that the elastic support member 3 is used to support and position the mounting frame 12, thereby ensuring the stability of the fins 13 and the row tubes 14; The spring 33 is the main supporting structure in the elastic support member 3. The support frame of multiple springs 33 can achieve stable support and positioning of the mounting frame 12, and also make the mounting frame 12 have a certain floating amount. Therefore, when it is subjected to the centrifugal force generated by the rotation of the eccentric counterweight block 64, it can generate vibration itself.

[0031] The specific use process of the device is as follows: (1) Crushing and collecting frost; The ultrasonic wave emitted by the ultrasonic generator is used to break the frost on the fins 13 and the drain pipe 14. Part of the frost is taken away by the airflow generated by the fan 11, and part of the frost falls into the water receiving bucket 43 under the action of gravity, and enters the discharge pipe 44 through the discharge pipe 42, and is finally discharged from the discharge pipe 44. (2) Accelerating liquid discharge through a medium-driven mechanism; The medium driving mechanism 5 is located at the downwind position of the fan 11. When the fan 11 is running, the airflow will also act on the shell 55. The shell 55 is hemispherical, that is, one side is an outer convex surface and the other side is an inner concave surface. Therefore, when the airflow acts on the shell 55, a pressure difference will be formed on the two sides. The pressure difference is used to drive the rotating shaft 51 to rotate. The rotating shaft 51 has a spiral plate 52. The spiral plate 52 is located inside the drainage pipe 42. Therefore, during the rotation process, it can promote the directional flow of the medium inside the drainage pipe 42 to facilitate the discharge of collected water; and during the rotation of the rotating shaft 51 and the spiral plate 52, a certain amount of heat will be generated due to friction. The heat is concentrated inside the drainage pipe 42, which can melt the frost that falls into the drainage pipe 42. After melting, it is more convenient to discharge it, and it can also avoid the situation of ice forming inside the drainage pipe 42. (3) driving the mounting frame to vibrate through a vibration drive mechanism; The mounting frame 12 is mounted inside the housing 1 through the elastic support member 3, so it has a certain amount of floating; In the vibration drive mechanism 6, the driving pulley 61 is installed on the rotating shaft 51, and when the rotating shaft 51 rotates, it can directly drive the driving pulley 61 to rotate; the positioning shaft 62 rotates on the mounting frame 12, and a driven pulley 63 and an eccentric counterweight 64 are fixed on the positioning shaft 62. Therefore, when the driving pulley 61 rotates, the positioning shaft 62 can be driven to rotate at high speed through the transmission belt 65, and then the eccentric counterweight 64 can be driven to rotate together. The eccentric counterweight 64 will generate centrifugal force when rotating. Under the action of this centrifugal force, the mounting frame 12 and the fins 13 and the row pipes 14 installed therein will vibrate, which is used to replace the vibration generator, so that it can cooperate with the ultrasonic generating device 2 to break the frost on the fins 13 and the row pipes 14.

[0032] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
