Description

Technical Field

[0001] This utility model relates to the field of heat pump technology, specifically a heat pump with a preheating device before startup. Background Technology

[0002] A heat pump is an energy-saving device that uses high-grade energy to transfer heat from a low-grade heat source to a high-grade heat source. As a major energy-saving device for heat energy at present, heat pumps have also been greatly promoted with the development of the times and technology. In terms of appearance, they are gradually becoming smaller, while in terms of internal structure, the functionality and practicality have been greatly improved. Before use, air source heat pumps need to be preheated. By using a preheating device to heat the chamber where the internal working components of the air source heat pump are located, the operating speed and stable start-up state can be improved.

[0003] A search revealed a preheating device for an air source heat pump, with publication number CN216522429U. In this application, the preheating cylinder and the connecting cylinder are fixed by bolts. However, during installation, the preheating cylinder needs to be manually supported continuously to align the bolt holes. If accidental contact or exhaustion occurs during operation, the hole position can easily shift, requiring repeated adjustments. This not only increases the difficulty of installation but also significantly reduces efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a heat pump with a preheating device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a heat pump with a preheating device, comprising a heat pump body, a pump core installed inside the heat pump body, a door panel installed on the outer surface of the heat pump body, a connecting cylinder snapped onto the right side surface of the heat pump body, an installation cylinder installed on the outer surface of the connecting cylinder, and docking components and protective components provided inside and on the surface of the connecting cylinder and the installation cylinder.

[0006] A cavity, the cavity being used to stabilize its internal mechanisms;

[0007] A circular ring, used to drive the connecting rod and the locking block to move radially synchronously;

[0008] The card block is used to limit the movement of the card slot.

[0009] Preferably, the cavity is located inside the connecting cylinder. A locking block is slidably connected to the inner wall of the cavity, penetrating the connecting cylinder. A ring is rotatably connected to the inner wall of the cavity on the side away from the locking block. An arc-shaped groove is formed on the outer surface of the ring. A connecting rod is fixed to the side of the locking block away from the cavity. A spring is fixed to the end of the locking block away from the center of the connecting cylinder. The end of the spring away from the locking block is fixed to the inner wall of the cavity. A slot is formed on the outer surface of the mounting cylinder. A handle is fixed to the outer surface of the ring. A through hole is formed on the outer surface of the connecting cylinder. The end of the handle away from the ring passes through the through hole. When the mounting cylinder is inserted into the connecting cylinder, its outer wall will press against the inclined surface of the locking block, causing the locking block to retract and compress the spring. When the locking block aligns with the slot, the spring rebounds and locks it into the slot, achieving automatic locking for easy subsequent fixation. To unlock, rotating the handle drives the ring to rotate. The inner wall of the arc-shaped groove abuts against the surface of the connecting rod, causing each locking block to move radially synchronously and disengage from the slot. At this point, the component can be safely separated for maintenance.

[0010] Preferably, the protective component includes a limiting groove located on the right side surface of the heat pump body. A connecting hole is provided on the outer surface of the handle. A sliding rod is slidably connected to the inner wall of the connecting hole. A sliding groove is provided on the outer surface of the sliding rod. A locking rod is slidably connected to the inner wall of the sliding groove. A second spring is fixed to the outer surface of the locking rod, with the end of the second spring away from the locking rod fixed to the inner wall of the sliding groove. A third spring is fixed to the outer surface of the sliding rod, with the end of the third spring away from the sliding rod fixed to the inner wall of the connecting hole. Two sets of limiting grooves are provided. Pulling the sliding rod causes the locking rod to move and compress the third spring. Simultaneously, the inclined surface of the locking rod abuts against the inclined surface of the limiting groove, causing the locking rod to slide into the sliding groove and compress the second spring. At this point, the handle can be freely rotated to release the limiting position. When the handle is rotated in the opposite direction until the locking rod aligns with one set of limiting grooves, both springs are released, pushing the locking rod back to its original position and locking it into the limiting groove, thereby locking the handle position, preventing accidental unlocking, and ensuring a secure connection.

[0011] Preferably, a ventilation pipe is installed on the top of the heat pump body, a ventilation window is installed on the left side of the heat pump body, an electric heating grid is installed on the inner side of the connecting cylinder, a motor is installed on the inner side of the mounting cylinder, a door panel is installed on the outer surface of the heat pump body, and a fan blade is fixed on the output shaft surface of the motor. Turning on the motor and the electric heating grid can preheat the pump core.

[0012] Preferably, the end of the locking block away from the spring is set as an inclined surface, which allows the locking block to move when it is pressed, facilitating docking and installation.

[0013] Preferably, the limiting groove is set as an inclined surface. When the sliding rod is pulled, the locking rod can move on its inclined surface and move into the sliding groove, which facilitates the subsequent rotation of the handle.

[0014] Compared with the prior art, this utility model provides a heat pump with a preheating device before startup, which has the following beneficial effects:

[0015] 1. This heat pump with a preheating device, via a docking assembly, allows for easy installation. When installation is required, the mounting cylinder inserts into the connecting cylinder, pressing against the inclined surface of the locking block, causing the locking block to retract and compress the spring. When the locking block aligns with the slot, the spring rebounds, locking it into the slot for automatic locking. This facilitates subsequent bolt fixing without the need for manual assistance, preventing accidental contact or misalignment due to insufficient force. To unlock, rotating the handle rotates the ring, causing the inner wall of the arc-shaped groove to contact the surface of the connecting rod, which in turn moves each locking block radially out of the slot, allowing for safe separation of the component for maintenance.

[0016] 2. The heat pump with a preheating device can lock the handle position by rotating the handle until the locking rod is aligned with a set of limiting grooves through the protective components. Springs 2 and 3 push the locking rod to reset and lock it into the limiting groove. The surface of the locking rod abuts against the side of the limiting groove away from the inclined surface, thus locking the handle position and preventing accidental unlocking, ensuring a stable connection.

[0026] like Figures 1-8 As shown, this utility model provides a technical solution: a heat pump with a preheating device, including a heat pump body 1, a pump core 5 installed inside the heat pump body 1, a door panel 4 installed on the outer surface of the heat pump body 1, a connecting cylinder 6 snapped onto the right side surface of the heat pump body 1, an installation cylinder 7 installed on the outer surface of the connecting cylinder 6, and a docking assembly 8 and a protective assembly 9 provided inside and on the surface of the connecting cylinder 6 and the installation cylinder 7; a cavity 80, a ring 81, a connecting rod 82, an arc groove 83, a locking block 84, a spring 85, a slot 86, a handle 87, and a through hole 88.

[0027] A cavity 80 is formed inside the connecting cylinder 6. A locking block 84 is slidably connected to the inner wall of the cavity 80, and the locking block 84 passes through the connecting cylinder 6. A ring 81 is rotatably connected to the inner wall of the cavity 80 away from the locking block 84. An arc-shaped groove 83 is formed on the outer surface of the ring 81. A connecting rod 82 is fixed to the side of the locking block 84 away from the cavity 80. A spring 85 is fixed to the end of the locking block 84 away from the center of the connecting cylinder 6. The end of the spring 85 away from the locking block 84 is fixed to the inner wall of the cavity 80. A locking groove 86 is formed on the outer surface of the mounting cylinder 7. A handle 87 is fixed to the outer surface of the ring 81. A through hole 88 is formed on the outer surface of the connecting cylinder 6. The end of the handle 87 away from the ring 81 passes through the through hole 88. The end of the locking block 84 away from the spring 85 is set as an inclined surface. When the mounting cylinder 7 and the connecting cylinder 6 are inserted, the outer surface of the mounting cylinder 7 will abut against the inclined surface of the locking block 84, forcing the locking block 84 to move towards the center of the cavity 80 and compress the spring 85. When the locking block 84 is aligned with the slot 86, the spring 85 is released, pushing the locking block 84 into the slot 86. At this time, the side of the locking block 84 away from the inclined surface abuts against the inner wall of the slot 86, realizing the automatic limiting of the connecting cylinder 6 and the mounting cylinder 7. No manual support is required and displacement is prevented, which facilitates subsequent bolt fixing and improves installation efficiency. When the limit needs to be released, rotating the handle 87 in the forward direction drives the ring 81 to rotate. Through the cooperation of the arc groove 83 and the connecting rod 82, the locking block 84 is radially disengaged from the locking groove 86. When the locking rod 93 is aligned with another set of limiting grooves 90, the slide rod 92 is released. The spring 3 96 pushes the slide rod 92 and the locking rod 93 to reset and lock into the limiting groove 90. At the same time, the spring 2 95 is released, causing the locking rod 93 to abut against the inner wall of the limiting groove 90, thereby fixing the handle 87. At this time, the installation cylinder 7 can be safely separated for maintenance.

[0028] The protective component 9 includes a limiting groove 90, which is located on the right side surface of the heat pump body 1. A connecting hole 91 is provided on the outer surface of the handle 87. A slide rod 92 is slidably connected to the inner wall of the connecting hole 91. A slide groove 94 is provided on the outer surface of the slide rod 92. A locking rod 93 is slidably connected to the inner wall of the slide groove 94. A second spring 95 is fixed to the outer surface of the locking rod 93. The end of the second spring 95 away from the locking rod 93 is fixed to the inner wall of the slide groove 94. A third spring 96 is fixed to the outer surface of the slide rod 92. The end of the third spring 96 away from the slide rod 92 is fixed to the inner wall of the connecting hole 91. Two sets of limiting grooves 90 are provided. The limiting grooves 90 are set as inclined surfaces. When the slide rod 92 is pulled, the locking rod 93 moves accordingly and compresses the third spring 96. At the same time, the inclined surface of the locking rod 93 abuts against the inclined surface of the limiting groove 90, so that the locking rod 93 slides into the slide groove 94 and compresses the second spring 95. At this time, the handle 87 can be rotated freely. When the handle 87 is rotated in the opposite direction until the locking rod 93 is aligned with a set of limiting grooves 90, the second spring 95 and the third spring 96 are released, pushing the locking rod 93 to reset and lock into the limiting groove 90, thereby locking the handle 87 and preventing accidental contact that could cause the locking block 84 to disengage from the locking groove 86, thus ensuring the connection stability between the connecting cylinder 6 and the mounting cylinder 7.

[0029] A ventilation pipe 2 is installed on the top of the heat pump body 1, a ventilation window 3 is installed on the left side of the heat pump body 1, an electric heating net 11 is installed on the inside of the connecting cylinder 6, a motor 10 is installed on the inside of the mounting cylinder 7, a door panel 4 is installed on the outer surface of the heat pump body 1, and a fan blade is fixed on the output shaft surface of the motor 10. When the motor 10 and the electric heating net 11 are turned on, the fan blade rotates and blows air onto the electric heating net 11, which allows hot air to enter the heat pump body 1 and preheat the pump core 5.

[0030] During installation, the mounting cylinder 7 is inserted into the connecting cylinder 6. At this time, the outer surface of the mounting cylinder 7 abuts against the inclined surface of the locking block 84, allowing the locking block 84 to move closer to the center of the cavity 80. Simultaneously, the spring 85 is compressed. When the locking block 84 is parallel to the slot 86, the spring 85 is released, causing the locking block 84 to enter the slot 86. At this point, the side of the locking block 84 away from the inclined surface abuts against the inner wall of the slot 86, thus mutually limiting the positioning of the connecting cylinder 6 and the mounting cylinder 7. This eliminates the need for manual handling and prevents... In case of accidental displacement, the pump can be secured normally with bolts, improving installation efficiency. During use, turn on motor 10 and heating network 11. The fan blades will rotate and blow air onto the heating network 11, allowing hot air to enter the heat pump body 1 and preheat the pump core 5. When the mounting cylinder 7 needs to be removed for maintenance after prolonged use, remove the bolts. Pulling the sliding rod 92 will simultaneously move the locking rod 93, compressing the spring 96. At this point, the surface of the locking rod 93 abuts against the inclined surface of the limiting groove 90. When the lever 93 enters the slide groove 94, the spring 95 is compressed, and the handle 87 can be rotated normally. At this time, the ring 81 rotates clockwise, and the inner wall of the arc groove 83 abuts against the surface of the connecting rod 82, which synchronously drives the locking block 84 to move radially and disengage from the locking groove 86, thereby releasing the limit. When the lever 93 is parallel to another set of limiting grooves 90, the slide rod 92 is released. At this time, the spring 96 is released, which drives the slide rod 92 and the lever 93 to reset and enter the limiting groove 90. At the same time, the spring 95 is released. At this point, the surface of the locking rod 93 contacts the side of the limiting groove 90 away from the inclined plane, which limits the locking rod 93, the sliding rod 92, and the handle 87. At this time, the installation cylinder 7 can be separated normally for maintenance. When separating, pull the sliding rod 92 again and reverse the handle 87 so that the locking rod 93 enters a set of limiting grooves 90, which limits the handle 87. This can prevent external accidental contact and separation of the locking block 84 from the locking groove 86, which would affect the stability of the connecting cylinder 6 and the installation cylinder 7, and reset the ring 81, making it easy to continue normal installation.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
