[0020] The present invention is described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-9 As shown, the indoor unit of the energy storage low-temperature variable frequency heat pump system includes an indoor unit body 100, a driving cavity 80 is formed in the indoor unit body 100, and the driving cavity 80 is provided with a heat pump component and a pipeline system 300 connected to the heat pump component.

[0022] The heat pump assembly includes a heat pump body and an insulation assembly arranged on the heat pump body, the insulation assembly includes an insulation shell 1 sleeved on the heat pump body, the insulation shell 1 includes a first shell 11 and a second shell 12 axially spliced ​​with each other, a hollow hole 15 is coaxially formed between the first shell 11 and the second shell 12, a connecting shaft 14 is passed through the first guide hole 13, and the connecting shaft 14 is formed with a hollow hole 15 for hot water to pass through, a top guide sleeve 16 connected to a plurality of connecting shafts 14 is installed on the top of the first shell 11, and the top guide sleeve 16 is formed with a top water storage chamber 191 connected to the hollow hole 15 and a top water storage chamber 191 connected to the hollow hole 15. The top water storage chamber 191 is connected to the water inlet 17 and the drain outlet 18; the first shell 11 and the second shell 12 are sleeved on the heat pump body, so that the heat pump body can be separated from the outside world, the heat dissipation efficiency of the heat pump body can be reduced, and the heat preservation effect can be achieved; through the cooperation of the connecting shaft 14 and the top guide sleeve 16, hot water is supplied to the connecting shaft 14, and the connecting shaft 14 cooperates with the first shell 11 and the second shell 12 respectively to achieve heat preservation for the first shell 11 and the second shell 12, so that the heat pump body nested in the first shell 11 and the second shell 12 can achieve a heat preservation effect and reduce heat loss.

[0023] The insulation shell 1 has a heat-insulating layered structure 27, and the layered structure 27 includes an inner insulation layer 28 that fits the heat pump body. The layered structure 27 also includes an outer insulation layer 29, and a heat-conducting layer 30 is arranged between the outer insulation layer 29 and the inner insulation layer 28. The inner insulation layer 28 and the outer insulation layer 29 are both formed by heat-insulating cotton material, and have good heat-insulating effect and heat-insulating effect. The heat-conducting layer 30 is formed by stainless steel material, and has good heat-conducting effect. The temperature of the connecting shaft 14 can be quickly transferred to the heat-conducting layer 30, maintaining the temperature of the insulation shell 1, preventing the heat loss of the heat pump, and the temperature is relatively stable.

[0024] The outer diameters of the first shell 11 and the second shell 12 are the same, the length of the connecting shaft 14 is greater than the total length of the first shell 11 and the second shell 12, and the first guide holes 13 of the first shell 11 and the second shell 12 are sleeved with a heat-conducting copper sleeve 10. In this embodiment, after the heat-insulating shell 1 is disassembled and installed on a heat pump of other lengths, the first shell 11 and the second shell 12 can slide with the connecting shaft 14 through the heat-conducting copper sleeve 10 of the first guide hole 13, so that the length of the heat-insulating shell 1 changes, and it can be applied to heat pumps of various lengths, and heat insulation of heat pumps of different sizes is further improved, and the practicality is further improved.

[0025] Furthermore, the heat preservation shell 1 further includes a third shell 2 axially sliding between the first shell 11 and the second shell 12, and the inner diameter of the third shell 2 is larger than the outer diameter of the first shell 11 and the second shell 12; when the first shell 11 and the second shell 12 are separated from each other to form a longer heat preservation shell 1, the third shell 2 can move to the gap between the first shell 11 and the second shell 12 to prevent the heat of the heat pump from being lost from the gap.

[0026] Furthermore, the outer surfaces of the first shell 11 and the second shell 12 are formed with a raised outer guide rail 21 along the length direction, and the inner wall of the third shell 2 is formed with a guide groove 22 that slides with the outer guide rail 21. When the third shell 2 slides, it slides with the outer guide rail 21 through the formed guide groove 22. When the third shell 2 slides, it will not rotate, thereby ensuring the stability of movement.

[0027] The first shell 11 and the second shell 12 are respectively radially formed with first connecting holes 23 that penetrate therethrough, and the first connecting hole 23 is installed with a first elastic connecting rod 44 that can be loosely connected to the heat pump body; after the first shell 11 and the second shell 12 move, the first elastic connecting rod 44 is threadedly matched with the first connecting hole 23, and the inner end of the first elastic connecting rod 44 can be in frictional contact with the outer wall of the heat pump to achieve an elastic connection, thereby reducing the probability of axial displacement of the first shell 11 and the second shell 12.

[0028] The third shell 2 is radially formed with a second connecting hole 25 that penetrates through it, and the second connecting hole 25 is equipped with a second elastic connecting rod 26 that can be loosely or tightly connected to the first shell 11 and the second shell 12; similarly, after the third shell 2 is moved to the specified position, the second elastic connecting rod 26 is threadedly engaged with the second connecting hole 25, and the inner end of the second elastic connecting rod 26 can be in frictional contact with the outer wall of the first shell 11 or the second shell 12 to achieve an elastic connection, thereby reducing the probability of axial displacement of the third shell 2.

[0029] The pipeline system 300 includes a support frame 3 and a plurality of pipelines 30 installed on the support frame 3. One end of the pipeline 30 is connected to the heat pump body through a joint, and the other end is connected to the source of the water source through a joint. The support frame 3 includes a pair of longitudinal support rods 31 arranged at intervals in the longitudinal direction and a transverse support rod 4 installed between the two longitudinal support rods 31. The transverse support rod 4 is installed with a plurality of clamping structures 40 arranged at intervals in the transverse direction. The clamping structure 40 includes a mounting sleeve for the pipeline 30 to pass through and an adjusting member for adjusting the tightness of the mounting sleeve and the pipeline 30. Sliding blocks 33 are respectively installed at both ends of the transverse support rod 4. The longitudinal support rod 31 is arranged with a longitudinal guide rail 32 for guiding the sliding of the sliding block 33 along the length direction. The longitudinal guide rail 32 is formed with a longitudinal mounting groove 34 along the length direction, and the sliding block 33 is formed with a transverse connecting hole matched with the longitudinal mounting groove 34. When the longitudinal position of the transverse support rod 4 is adjusted, the bolts and nuts inserted through the transverse connecting hole and the longitudinal mounting groove 34 are locked and matched to fix the transverse support rod 4.

[0030] The transverse support rod 4 can be slidably matched with the longitudinal guide rail 32 of the longitudinal support rod 31 through the sliding block 33 to adjust the height of the transverse support rod 4. The position of the clamping structure 40 used to install the pipe 30 changes accordingly, and the pipes 30 of different lengths can be clamped and installed, and the practicality is further improved. The clamping structure 40 can adjust the tightness of the clamping with the pipe 30 through the cooperation of the mounting sleeve and the adjusting part, so as to facilitate the looseness or tightness of the pipe 30 in the clamping structure 40 and adjust the position where the clamping structure 40 is connected to the pipe 30.

[0031] The clamping structure 40 also includes a fixing seat 41 fixed on the transverse support rod 4. The mounting sleeve is U-shaped and includes a semicircular ring 43 surrounding and contacting the pipe 30 and a connecting rod 44 slidably mounted on the fixing seat 41. The connecting rod 44 and the semicircular ring 43 are integrally formed and connected.

[0032] The fixing seat 41 is formed with a semicircular groove 42 that cooperates with the semicircular ring 43. The semicircular groove 42 semi-surrounds a part of the pipe 30, and the semicircular ring 43 semi-surrounds another part of the pipe 30. The semicircular groove 42 and the semicircular ring 43 form a clamping sleeve for clamping the pipe 30; a pipe 30 is clamped by the clamping sleeves of multiple clamping structures 40, which can improve the clamping stability of the pipe 30.

[0033] Preferably, the semicircular groove 42 is formed with a first serrated groove 45 arranged longitudinally, and the surface of the pipe 30 is formed with a second serrated groove 46 that cooperates with the first serrated groove 45 along the length direction. When the clamping sleeves of the multiple clamping structures 40 are clamped, the first serrated groove 45 of the semicircular groove 42 will frictionally cooperate with the second serrated groove 46 of the pipe 30, thereby increasing the contact friction force, further reducing the probability of slipping due to the gravity of the pipe 30, and further improving the clamping of the pipe 30.

[0034] The fixing seat 41 is formed with an adjustment groove 47 for the connecting rod 44 to slide through, and the transverse support rod 4 is formed with an adjustment hole 48 coaxially matched with the adjustment groove 47, and a locking nut is installed outside the adjustment hole 48 for loose connection with the connecting rod 44; when it is necessary to adjust the tightness of the clamping structure 40 and the pipeline 30, the locking nut is loosened, and the transverse support rod 4 slides along the adjustment hole 48 and the adjustment groove 47, and the semicircular ring 43 moves away from the semicircular groove 42. At this time, the pipeline 30 can be moved longitudinally, or the transverse support rod 4 can be moved longitudinally to adjust the connection position of the clamping structure 40 and the pipeline 30.

[0035] In addition, the transverse support rod 4 is formed with a plurality of spaced transverse sliding grooves 5 along the length direction. The fixing seat 41 can adjust the transverse position of the fixing seat 41 by slidingly cooperating with the transverse sliding groove 5 through the connecting rod 44. When the locking nut is loosened, the fixing seat 41 can be moved so that the transverse position of the fixing seat 41 is easy to adjust to adjust the distance between two adjacent pipes 30. After adjusting the spacing, it will not affect the installation of other equipment in the chassis, which is convenient for optimizing the installation structure of the heat pump system.

[0036] Preferably, the transverse support rod 4 is also provided with a buffer seat 51 located between two adjacent clamping structures 40, the buffer seat 51 is formed with a longitudinally arranged connecting seat 52, and buffer blocks 53 that pop out laterally for buffering are installed at both ends of the connecting seat 52, and the buffer block 53 is formed with an arc-shaped contact groove 54 that contacts the arc surface of the pipe 30; after the pipe 30 is installed on the support frame 3, the arc-shaped contact groove 54 of the buffer block 53 will contact the side wall of the pipe 30, forming a secondary installation protection for the spaced pipes 30, and further preventing the pipes 30 from lateral displacement.

[0037] Specifically, the connecting seat 52 is formed with a transversely arranged second guide hole 55, and a second guide rod 56 is slidably installed in the second guide hole 55. The buffer block 53 is installed at the outer end of the second guide rod 56, and a compression spring 57 is arranged in the second guide hole 55 and is nested in the second guide rod 56; under the elastic drive of the compression spring 57, the second guide rod 56 will pop out axially along the second guide hole 55, and the arc-shaped contact groove 54 of the buffer block 53 will form a surface contact with the side wall of the pipe 30, so as to further clamp and fix the two adjacent pipes 30.

[0038] The indoor unit body 100 includes a casing, the casing 6 is provided with a fan assembly 60, the fan assembly 60 includes an exhaust slot 61 formed on the casing 6, the exhaust slot 61 is provided with a rotatable fan blade 62, the exhaust slot 61 is a circular slot, the fan assembly 60 also includes a blade cylinder 63, the blade cylinder 63 is formed with three fan blades 62, and the angles between two adjacent fan blades 62 are the same. The casing 6 is provided with a blocking net 68 that blocks the exhaust slot 61.

[0039] The fan assembly 60 also includes a driving motor 64 installed on the exhaust slot 61, and a motor shaft 65 is installed on the driving end of the driving motor 64. The fan tube is formed with a snap-in hole 66 connected to the motor shaft 65; the fan blade tube 63 is snap-connected to the motor shaft 65 through the snap-in hole 66. When the motor shaft 65 rotates, the fan tube is not easy to fall off, thereby ensuring the stability of the connection.

[0040] The fan blades 62 are detachably mounted with a dust removal component 7 for scraping dust off the wall of the exhaust slot 61; the dust removal component 7 includes a third guide hole 71 formed on the outer wall of the fan blades 62, and a mounting column 72 can be inserted into the third guide hole 71. An arc-shaped mounting plate 77 is mounted between the plurality of mounting columns 72, and a sponge block 67 in contact with the wall of the exhaust slot 61 is mounted on the outer end of the mounting plate 77.

[0041] When it is necessary to remove dust from the groove wall of the exhaust groove 61, the mounting column 72 of the mounting plate 77 can be inserted into the third guide hole 71 of the fan blade 62. At this time, the sponge block 67 will press against the groove wall of the exhaust groove 61 under the action of deformation. Then the fan assembly 60 works and rotates. The sponge block 67 will frictionally contact with the groove wall of the exhaust groove 61, thereby achieving dust removal on the groove wall of the exhaust groove 61. There is no need to remove the fan blade 62, the efficiency is greatly improved, and the dust removal effect is better.

[0042] Preferably, the third guide hole 71 is formed with an internal threaded hole 73, the mounting column 72 is formed with an external threaded hole 74 of a hollow structure, the internal threaded hole 73 and the external threaded hole 74 are coaxially aligned; the mounting plate 77 is formed with an insertion hole 75 coaxially aligned with the internal threaded hole 73 and the external threaded hole 74, and the insertion hole 75 is penetrated by a threaded rod 76. In this embodiment, when the mounting plate 77 needs to be installed, the mounting column 72 is first inserted into the third guide hole 71, so that the internal threaded hole 73 in the third guide hole 71 is coaxially aligned with the external threaded hole 74 of the mounting column 72, and then the threaded rod 76 is inserted from the insertion hole 75, and the mounting column 72 is connected to the third guide hole 71, so as to achieve fixed installation of the mounting seat, and the fan blades 62 will not fall off when rotating, thereby ensuring stability during dust removal.

[0043] Furthermore, a Velcro 78 is attached to the back of the sponge block 67, and a gauze block 79 attached to the Velcro 78 is attached to the mounting plate 77; the gauze block 79 is connected to the mounting plate 77 via the Velcro 78, so that when the sponge block 67 is damaged, it is easy to disassemble and replace.
