Description

Technical Field

[0001] This utility model relates to the field of air source heat pumps, and in particular to the external protective structure of energy-saving air source heat pump units. Background Technology

[0002] Air source heat pump units, as indispensable heating and cooling supply equipment in modern buildings, have a complex and precise internal structure, including a series of core components such as compressors, condensers, and evaporators. The normal operation of these components depends on a relatively clean and stable environment; therefore, to protect the unit and ensure its proper functioning, relevant protective mechanisms have been developed.

[0003] In existing technologies, common air source heat pump units are usually installed outdoors, and their vents are all open designs. This leads to a problem: when the air source heat pump unit is not in operation, the open vents become a potential hazard. Dust, sand, and other external impurities can easily enter the unit's casing through these unprotected vents. Once inside, these impurities may adhere to the precision components inside the unit, such as heat sinks, fan blades, and circuit boards, thus seriously affecting the unit's performance. For example, dust accumulation will reduce the heat dissipation efficiency of the heat sinks, leading to excessively high unit operating temperatures, increased energy consumption, and shortened equipment lifespan. Sand intrusion may wear down fan blades, generating noise and even causing mechanical failures. Dust accumulation on circuit boards may even cause electrical problems such as short circuits, seriously threatening the safe operation of the unit. Moreover, the problem of impurity intrusion will be further exacerbated in extreme weather conditions. Therefore, it is necessary to improve the external protection structure of energy-saving air source heat pump units to solve the above problems. Utility Model Content

[0004] To overcome the problem that when an air source heat pump unit is not in use, external impurities and other contaminants can enter the protective casing through the open vents and affect the unit's components.

[0005] The technical solution of this utility model is as follows: an external protective structure for an energy-saving air source heat pump unit, including a device shell, a first motor and a support mechanism, a movable door rotatably connected to the device shell, a support mechanism for supporting the device shell at the bottom of the device shell, a first motor fixedly connected inside the device shell, a first rotating gear fixedly connected to the output end of the first motor, a first sliding rack slidably connected inside the device shell, the first sliding rack meshing with the first rotating gear, a first fixed frame fixedly connected to the first sliding rack, a first sliding rod slidably connected inside the first fixed frame, a first opening and closing flap rotatably connected inside the device shell, a first connecting rod fixedly connected between the first sliding rod and the first opening and closing flap, a first fixed rod fixedly connected to the first sliding rack, a second fixed frame fixedly connected to the first fixed rod, a second opening and closing flap rotatably connected inside the device shell, and a second connecting rod fixedly connected between the second opening and closing flap and the second sliding rod.

[0007] Preferably, a fixed inner frame is fixedly connected inside the device housing, a second motor is fixedly connected to the fixed inner frame, a rotating disk is fixedly connected to the output end of the second motor, a second fixed rod is fixedly connected to the rotating disk, a second sliding rack is slidably connected to the fixed inner frame, a connecting block is fixedly connected to the second sliding rack, the second fixed rod is slidably connected inside the connecting block, a second rotating gear is meshed with the outside of the second sliding rack, a rotating shaft is fixedly connected inside the second rotating gear, the rotating shaft is rotatably connected inside the fixed inner frame, a cooling fan body for dissipating heat from the inside of the device housing is provided on the rotating shaft, a fixed block is fixedly connected to the device housing, a sliding latch is slidably connected inside the fixed block, the sliding latch is latched inside the movable door, a toggle block is fixedly connected to the sliding latch, and a first spring is fixedly connected between the sliding latch and the fixed block.

[0008] Preferably, the fixed inner frame has a groove at the relative position of the second sliding rack, and the second sliding rack is slidably connected inside the groove.

[0009] Preferably, the connecting block has a groove at the relative position of the second fixed rod, and the second fixed rod is slidably connected inside the groove.

[0010] Preferably, the support mechanism includes a knob that is rotatably connected to the bottom of the device housing. A sliding seat is threadedly connected to the inside of the knob. A guide rod is fixedly connected to the bottom of the device housing. The sliding seat is slidably connected to the outside of the guide rod. A support rod is fixedly connected to the bottom of the sliding seat. A support base is movably connected to one end of the support rod.

[0011] Preferably, the device housing has a groove at the relative position of the knob, and the knob is rotatably connected inside the groove.

[0012] The beneficial effects of this utility model are:

[0013] 1. Compared to traditional open vents, the sliding of the first sliding rack drives the opening and closing of the first and second opening and closing blades. In the face of extreme weather, by controlling the opening and closing of the vents, external factors are prevented from entering the device casing and damaging the internal components through physical isolation. This increases the service life of the internal air source heat pump unit and avoids the problem of external impurities entering the protective casing and affecting the unit components when the air source heat pump unit is not in use.

[0014] 2. Compared to traditional heat dissipation mechanisms, the fixed position of the fan results in a more concentrated airflow. By cooperating with the second sliding rack and the second rotating gear, the cooling fan body is driven to oscillate back and forth within a certain angle range, allowing the airflow entering the device casing to cover the heat dissipation area more extensively. This further improves the heat dissipation efficiency, ensures the uniformity of the heat dissipation effect, and effectively avoids the occurrence of local overheating. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] Please see Figure 1 - Figure 9This utility model provides an embodiment of an energy-saving air source heat pump unit's external protective structure, including a device housing 1, a first motor 21, and a support mechanism. A movable door 4 is rotatably connected to the device housing 1. A support mechanism for supporting the device housing 1 is provided at the bottom of the device housing 1. The first motor 21 is fixedly connected inside the device housing 1. A first rotating gear 22 is fixedly connected to the output end of the first motor 21. A first sliding rack 23 is slidably connected inside the device housing 1, meshing with the first rotating gear 22. A first fixed frame 24 is fixedly connected to the first sliding rack 23. A first sliding rod 25 is slidably connected inside the first fixed frame 24. A first opening / closing flap 26 is rotatably connected inside the device housing 1. A first connecting rod 27 is fixedly connected between the first sliding rod 25 and the first opening / closing leaf 26. A first fixed rod 28 is fixedly connected to the first sliding rack 23. A second fixed frame 29 is fixedly connected to the first fixed rod 28. A second opening / closing leaf 211 is rotatably connected inside the device housing 1. A second connecting rod 212 is fixedly connected between the second opening / closing leaf 211 and the second sliding rod 210. During use, the device housing 1 is supported by a support mechanism to prevent the device housing 1 from shaking due to uneven ground. In extreme weather conditions, the first motor 21 operates, driving the first rotating gear 22 to rotate. When the first rotating gear 22 rotates, it drives the first sliding rack 23 and the first fixed rod 28 to move. When the first sliding rack 23 moves, it is driven by the first fixed frame 24. The first sliding rod 25 slides, causing the first opening / closing leaf 26 to close via the first connecting rod 27. When the first fixed rod 28 moves, it causes the second sliding rod 210 to slide via the second fixed frame 29. When the second sliding rod 210 slides, it causes the second opening / closing leaf 211 to close via the second connecting rod 212, thus sealing the device housing 1 and preventing external factors from entering. The device housing 1 has a groove at a relative position to the first sliding rack 23, which is slidably connected inside the groove. The groove restricts the sliding of the first sliding rack 23, preventing it from tilting and affecting its subsequent opening and closing of the first opening / closing leaf 26 and the second opening / closing leaf 211. The internal structure of the device housing 1 is fixed. A fixed inner frame 213 is connected to the device. A second motor 214 is fixedly connected to the fixed inner frame 213. A rotating disk 215 is fixedly connected to the output end of the second motor 214. A second fixed rod 216 is fixedly connected to the rotating disk 215. A second sliding rack 217 is slidably connected to the fixed inner frame 213. A connecting block 225 is fixedly connected to the second sliding rack 217. The second fixed rod 216 is slidably connected inside the connecting block 225. A second rotating gear 218 meshes with the outside of the second sliding rack 217. A rotating shaft 219 is fixedly connected inside the second rotating gear 218. The rotating shaft 219 is rotatably connected inside the fixed inner frame 213. A cooling fan body 220 for dissipating heat from the inside of the device housing 1 is provided on the rotating shaft 219.A fixing block 221 is fixedly connected to the outer casing 1 of the device. A sliding block 222 is slidably connected inside the fixing block 221. The sliding block 222 is engaged with the inside of the movable door 4. A lever 223 is fixedly connected to the sliding block 222. A first spring 224 is fixedly connected between the sliding block 222 and the fixing block 221. Through the cooperation of the second fixing rod 216 and the connecting block 225, the second sliding rack 217 is driven to slide back and forth, thereby causing the cooling fan body 220 to rotate back and forth. This prevents air from being blown into the inner casing 1 in a concentrated manner, increases the airflow area, and prevents local overheating caused by poor local heat dissipation. The inner frame 2 is fixed. A groove is provided at a relative position to the second sliding rack 217. The second sliding rack 217 is slidably connected inside the groove. The groove restricts the sliding of the second sliding rack 217, ensuring that it slides linearly on the fixed inner frame 213 and preventing it from tilting, which would affect its engagement with the second rotating gear 218. A groove is provided at a relative position to the second fixed rod 216. The second fixed rod 216 is slidably connected inside the groove. The groove restricts the sliding of the second fixed rod 216, preventing it from disengaging from the connecting block 225 and affecting the subsequent rotation of the cooling fan body 220.

[0028] Please see Figure 1 , Figure 10 In this embodiment, the support mechanism includes a knob 31, which is rotatably connected to the bottom of the device housing 1. A sliding seat 32 is threadedly connected to the inside of the knob 31. A guide rod 33 is fixedly connected to the bottom of the device housing 1. The sliding seat 32 is slidably connected to the outside of the guide rod 33. A support rod 34 is fixedly connected to the bottom of the sliding seat 32. One end of the support rod 34 is movably connected to a support base 35. The position of the support rod 34 and the support base 35 can be adjusted by rotating the knob 31 to avoid the support base 35 being suspended due to uneven ground, which would cause the device housing 1 to shake during subsequent use. A rotating groove is provided on the device housing 1 at the relative position of the knob 31. The knob 31 is rotatably connected to the inside of the rotating groove. The rotating groove restricts the rotation of the knob 31 to prevent the knob 31 from detaching from the device housing 1 when rotating, thus affecting its adjustment of the position of the sliding seat 32.

[0029] During operation, depending on the flatness of the ground, rotating knob 31 causes sliding seat 32 to slide outside guide rod 33, thereby adjusting the position of support rod 34 and support base 35. This ensures that support base 35 is in contact with the ground while adjusting the overall levelness of device housing 1, preventing shaking of device housing 1 due to uneven ground. In extreme weather conditions, the first motor 21 operates, driving the first rotating gear 22 to rotate. When the first rotating gear 22 rotates, it drives the first sliding rack 23 and the first fixed rod 28 to move. When the first sliding rack 23 moves, it drives the first sliding rod 25 to slide through the first fixed frame 24. When the first sliding rod 25 slides, it drives the first opening and closing leaf 26 to close through the first connecting rod 27. When the first fixed rod 28 moves, it drives the second sliding rod 210 to slide through the second fixed frame 29. When the second sliding rod 210 slides, it drives the second opening and closing leaf 211 to close through the second connecting rod 212, thereby sealing device housing 1 and preventing external factors from entering the device. Inside the housing 1, during use, the second motor 214 operates, driving the rotating disk 215 to rotate. When the rotating disk 215 rotates, it drives the second fixed rod 216 to rotate. When the second fixed rod 216 rotates, it cooperates with the connecting block 225 to drive the second sliding rack 217 to slide up and down. When the second sliding rack 217 slides, it cooperates with the second rotating gear 218 to drive the rotating shaft 219 and the cooling fan body 220 to rotate, thereby allowing air to be blown more fully onto the components inside the housing 1, further preventing overheating. When opening and closing the movable door 4 to inspect and maintain the components inside the housing 1, the sliding block 222 is slid by moving the toggle block 223, thereby engaging the locking mechanism of the movable door 4, thus opening the movable door 4 for inspection. After the inspection is completed, the movable door 4 is closed, the toggle block 223 is released, and the first spring 224 provides a pushing force to the sliding block 222, pushing the sliding block 222 back to its original position, thereby re-locking the movable door 4.

[0030] Through the above steps, compared with the traditional open vent, the sliding of the first sliding rack 23 drives the opening and closing of the first opening and closing leaf 26 and the second opening and closing leaf 211, so as to solve the problem that when the air source heat pump unit is not in use, external impurities and other things will enter the protective shell and affect its unit components.
