Description

Technical Field

[0001] This utility model relates to the field of outdoor unit technology, and in particular to a heat pump outdoor unit. Background Technology

[0002] The outdoor unit of a heat pump is a key component of a heat pump system. It mainly undertakes core functions such as heat exchange and refrigerant circulation power supply. Its operation directly affects the overall cooling or heating effect of the heat pump. It is an outdoor equipment unit in the heat pump system. By working with the indoor unit, it realizes the transfer of heat between indoor and outdoor spaces, thereby achieving the purpose of cooling or heating.

[0003] The existing utility model patent with publication number CN219367920U discloses an outdoor unit and a heat pump device. The heat pump device includes an indoor unit and an outdoor unit. The outdoor unit includes a housing and an electrical control box. The housing has a cavity, and the electrical control box is installed within the cavity. The electrical control box includes a circuit board assembly and a housing. The housing has a cavity, and the circuit board assembly is located within the cavity. The top of the housing has an opening communicating with the cavity. The circuit board assembly includes a circuit board and multiple electronic components, which are respectively arranged on opposite sides of the circuit board. This arrangement, specifically the design of the opening at the top of the housing, allows some electronic components to face the opening, facilitating wiring and installation of the electronic components on the circuit board, thus improving work efficiency. Furthermore, the multiple electronic components are respectively... The design incorporates multiple electronic components arranged on opposite sides of the circuit board, which reduces the board's size and space requirements, further minimizing the area occupied by the control box and improving space utilization. While this solves the problem of "inconvenient wiring, installation, and subsequent maintenance due to the inverted circuit board design in existing control boxes," a dust cover is typically installed on the outdoor unit of the heat pump to prevent dust from entering and interfering with the fan blades. However, traditional heat pump outdoor units usually use screws to fix the dust cover, requiring tools to remove each screw individually for cleaning. This process is time-consuming and labor-intensive, and frequent screw removal can damage or damage the threads, affecting the reinstallation of the dust cover. Therefore, a new type of heat pump outdoor unit is proposed. Utility Model Content

Example

[0032] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A heat pump outdoor unit includes an outdoor unit body 1. A dustproof plate 2 is provided on the front of the outdoor unit body 1 to reduce the interference of dust on the fan blades and internal parts inside the outdoor unit body 1. A pair of through holes 3 are provided on the top and bottom of the surface of the dustproof plate 2. The inner cavity can accommodate a fixing block 4 and an installation block 5. The dustproof plate 2 and the outdoor unit body 1 are assembled by cooperating with the fixing block 4. A pair of fixing blocks 4 are fixedly connected to the top and bottom of the front of the outdoor unit body 1.

[0033] Mounting block 5 is fixed to one side of the surface of fixing block 4. A side groove 6 is opened on one side wall of mounting block 5. An elastic limiting piece 7 is fixedly connected to the inner wall of the side groove 6. Two elastic limiting pieces 7 of the same height are symmetrically distributed. Through elastic deformation, the elastic limiting piece 7 passes through the through hole 3 and resets, leaving the range of the through hole 3 and abutting against part of the dustproof plate 2, so as to achieve quick positioning of the dustproof plate 2. An unlocking box 8 is set between the two mounting blocks 5 at the same height. A top ball 9 is set on both sides of the unlocking box 8. When unlocking the dustproof plate 2, the part of the elastic limiting piece 7 placed outside the side groove 6 is pushed into the side groove 6 to release the limitation on the dustproof plate 2.

[0034] Preferably, the positions of the four perforations 3 correspond to the four fixing blocks 4 respectively, and one side of the elastic limiting piece 7 is placed outside the mounting block 5.

[0035] Preferably, a movable rod 10 is provided on both sides of the inner cavity of the unlocking box 8. Two connecting blocks 11 are fixedly connected to the middle of the inner wall of the unlocking box 8. One end of the movable rod 10 slides through the inner wall of the top ball 9 and is fixedly connected to the top ball 9 on the same side. The other end of the movable rod 10 slides through the surface of the connecting block 11 and is fixedly connected to the unlocking block 13 for manual triggering of unlocking. A spring 12 is sleeved on the part of the movable rod 10 placed between the connecting block 11 and the inner wall of the unlocking box 8 to provide a reset elastic force for the top ball 9. The two ends of the spring 12 are respectively connected to the connecting block 11 and the inner wall of the unlocking box 8. The position of the top ball 9 corresponds to the position of the elastic limiting piece 7 on the same side. A top hole 14 is opened in the middle of the top of the unlocking box 8 for the unlocking block 13 to slide through and realize manual operation. A part of the unlocking block 13 moves through the inner cavity of the top hole 14 and is placed in the inner cavity of the connecting hole 16.

[0036] Preferably, a top plate 15 is fixedly connected to the top of the unlocking box 8. The two side walls of the top plate 15 extend to the top of the top ball 9, blocking the top ball 9 and the upper part of the elastic limiting piece 7. A connecting hole 16 is opened in the middle of the top of the top of the top plate 15. The inner cavity of the connecting hole 16 is connected to the inner cavity of the top hole 14. A sealing plate 17 is rotatably connected to the top of the top of the top plate 15. When not unlocked, the sealing plate 17 is closed to prevent rainwater and dust from entering the interior of the unlocking box 8, protect the internal spring 12, moving rod 10 and other parts, and extend the service life of the mechanism. One side of the sealing plate 17 is placed on the top of the connecting hole 16.

[0037] The usage process of the heat pump outdoor unit provided by this utility model is as follows: First, the operator aligns the perforation 3 on the dustproof plate 2 with the fixing block 4 on the front of the outdoor unit body 1, so that the fixing block 4 and the mounting block 5 are embedded in the perforation 3. During installation, the elastic limiting piece 7 in the side groove 6 of the mounting block 5 is squeezed by the inner wall of the perforation 3 and undergoes elastic deformation. After the elastic limiting piece 7 passes through the perforation 3, it returns to its original position by its own elasticity, and the outer part is removed from the range of the perforation 3 and abuts against the inner side of the dustproof plate 2, thus quickly positioning and fixing the dustproof plate 2 on the outdoor unit body 1. No tools are required to complete the installation of the dustproof plate 2. When it is necessary to remove the dustproof plate 2, the operator first rotates the sealing plate 17 to open the connecting hole 16 on the top plate 15, exposing the top hole 14. The unlocking block 13 is then moved by hand. The unlocking block 13 causes the moving rod 10 connected to it to slide inside the unlocking box 8. The ball 9 at one end of the moving rod 10 moves with the moving rod 10. The ball 9 pushes the part of the elastic limiting piece 7 placed outside the side groove 6 into the side groove 6, so that the elastic limiting piece 7 is released from the tight state with the dustproof plate 2, and the limitation on the dustproof plate 2 is released. At this time, the operator can easily remove the dustproof plate 2 from the outdoor unit body 1. After the unlocking block 13 is released, the spring 12 pushes the connecting block 11 due to the elastic potential energy, which drives the moving rod 10 and the ball 9 to reset. The unlocking block 13 returns to the initial position. Finally, the operator closes the sealing plate 17 to prevent rainwater and dust from entering the unlocking box 8 and protect the internal parts.
