Description

Technical Field

[0001] This utility model relates to the field of air source heat pump technology, and in particular to the vibration damping frame of an air source heat pump outdoor unit. Background Technology

[0002] An air source heat pump is a highly efficient and energy-saving device that utilizes high-grade energy to move heat from a low-grade heat source (air) to a high-grade heat source. It is widely used in homes and commercial settings. An air source heat pump mainly consists of an evaporator, compressor, condenser, and expansion valve, which work together to complete the compression, condensation, expansion, and evaporation of the refrigerant, thereby achieving heating and cooling effects.

[0003] Based on its operating principle, the outdoor unit of an air source heat pump needs to be placed in an open outdoor location, such as a rooftop or yard, ensuring good ventilation for sufficient heat exchange efficiency. During operation, the compressor draws in low-temperature, low-pressure refrigerant gas, which is then compressed by an internal motor that drives a piston, expelling high-temperature, high-pressure refrigerant gas to power the refrigeration cycle. The vibrations generated by the compressor's operation and the reciprocating motion of the piston cause resonance in the frame, especially at the connection between the metal outdoor unit casing and the rigid mounting structure, which easily interacts and generates noise. This noise can also affect the installation location through the rigid mounting structure. Even with sound insulation material at the compressor, the noise generated by these factors cannot be reduced. In open outdoor environments, this can have a certain impact on the surrounding environment. To solve these problems, it is necessary to improve the frame of the air source heat pump outdoor unit. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a vibration damping frame for an outdoor unit of an air source heat pump to solve the above problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a vibration damping frame for an outdoor unit of an air source heat pump, which includes the main shell of the outdoor unit, a mounting frame, corner elastic elements, and support columns.

[0007] The bottom of the outdoor unit's main casing has a pair of extended mounting pieces arranged side by side, each with screw holes. The mounting frame is a rectangular frame structure consisting of four frame sides. Each pair of frame sides of the mounting frame has two mounting waist-shaped holes along its length. A pair of first mounting beams and a pair of second mounting beams are connected across the paired frame sides of the mounting frame through the opposing mounting waist-shaped holes. The first and second mounting beams can slide within the mounting waist-shaped holes. Both the first and second mounting beams have parallel beam waist-shaped holes. The first mounting beam is covered with an elastic interlayer. The outdoor unit's main casing is screwed to the beam waist-shaped holes of the first mounting beams. The corner elastic element includes three elastic abutments that are perpendicular to each other. Each beam waist-shaped hole of the second mounting beam has a corresponding corner elastic element that is slidably connected to it, used to abut the four corners of the outdoor unit's main casing. The bottom of the support column is provided with elastic foot pads located below the mounting waist-shaped holes of the mounting frame.

[0008] Preferably, the vibration damping frame further includes a support beam located between two first mounting beams, and the support beam is covered with an elastic pad for supporting the main body shell of the outdoor unit.

[0009] Preferably, elastic corner pieces are provided at the corners between adjacent frame edges of the mounting frame, and the mutually perpendicular edges of the elastic corner pieces abut against different frame edges.

[0010] Preferably, the bottom of the mounting frame is also connected to a limiting post, and the bottom of the limiting post is provided with a metal gasket with a threaded hole.

[0011] Preferably, the side of the limiting column or supporting column is provided with a reinforcing rod that is obliquely connected to the mounting frame.

[0012] Preferably, the bottom of the metal gasket is also provided with an elastic interlayer.

[0013] Preferably, the elastic stop surface of the corner elastic element and the elastic interlayer on the first mounting beam are any one of the following material layers: rubber material layer, polyurethane material layer, and silicone material layer.

[0014] The technical effects achieved by this utility model include:

[0015] To address the resonance caused by compressor vibration during operation, the vibration-damping frame of the aforementioned air-source heat pump outdoor unit employs a multi-stage elastic connection structure. An elastic interlayer is sandwiched between the extended mounting plate and the first mounting beam, reducing resonance in the main connection areas between the outdoor unit's main casing and the mounting frame, effectively absorbing the longitudinal vibration energy generated by the compressor. Corner elastic elements abut against the four corners of the outdoor unit through three orthogonal elastic abutments, achieving three-dimensional constraint on vertical vibration. The support columns of this vibration-damping frame are equipped with elastic feet to support the mounting frame, contacting the surface at the installation location to reduce the impact of the air-source heat pump outdoor unit's vibration on the surface at the installation location. Therefore, this vibration-damping frame features a continuous multi-stage vibration-damping structure from the bottom of the outdoor unit's main casing to the surface at the installation location. Compared to traditional rigid frames, this multi-stage elastic damping structure achieves multi-dimensional vibration suppression, reducing noise impact on the surrounding environment and preventing vibration from affecting the stable operation of the core components inside the outdoor unit's main casing.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Examples of these preferred embodiments are illustrated in the drawings. The embodiments of this utility model shown in and described with reference to the drawings are merely exemplary, and this utility model is not limited to these embodiments.

[0027] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related are omitted.

[0028] like Figure 1 As shown, this utility model embodiment provides a vibration damping frame for an outdoor unit of an air source heat pump, which includes an outdoor unit main shell 1, a mounting frame 2, a corner elastic element 3, and a support column 4.

[0029] The bottom of the main body shell 1 of the outdoor unit is provided with an outer extension mounting piece 11, and the outer extension mounting piece 11 is provided with screw holes. Generally, the main body shell 1 of the outdoor unit has a cubic box structure.

[0030] Combination Figure 1 and Figure 2 As shown, the mounting frame 2 is a rectangular frame structure formed by four frame sides 201. Each pair of frame sides 201 of the mounting frame 2 has two mounting waist-shaped holes 20a along its length. A pair of first mounting beams 21 and a pair of second mounting beams 22 are transversely connected between the paired frame sides 201 through the opposing mounting waist-shaped holes 20a. The first mounting beams 21 and the second mounting beams 22 can slide within the mounting waist-shaped holes 20a, allowing both the parallel first mounting beams 21 and the second mounting beams 22 to move along the length of the connected frame sides 201. The two first mounting beams 21 are located inside the second mounting beams 22. Both the first mounting beams 21 and the second mounting beams 22 have two parallel beam waist-shaped holes 20b. Figure 2 and Figure 3 As shown, the first mounting beam 21 is covered with an elastic interlayer 211. The outer mounting piece 11 of the outer unit body shell 1 is fastened to the beam waist-shaped hole 20b of the first mounting beam 21 by screws, so that the elastic interlayer 211 is sandwiched between the first mounting beam 21 and the outer mounting piece 11. In this embodiment, there are four outer mounting pieces 11, which correspond to the beam waist-shaped holes 20b on the two first mounting beams 21 respectively.

[0031] The corner elastic element 3 includes three elastic abutments 31 that are perpendicular to each other. Each second mounting beam 22 has a corresponding corner elastic element 3 that is slidably connected to the beam waist-shaped hole 20b. The corner elastic element 3 is used to press against the four corners of the outdoor unit body shell 1. The corner elastic element 3 is provided with a positioning piece for installing screws. The position of the corner elastic element 3 is limited by locking it in the beam waist-shaped hole 20b of the second mounting beam 22 with screws.

[0032] The bottom of the support column 4 is provided with an elastic foot pad 41, which is located below the mounting waist-shaped hole 20a of the mounting frame 2.

[0033] The mounting joints of the outdoor unit's main casing 1 are concentrated at the lower part of its structure. The compressor is also generally installed vertically on the outdoor unit's main casing 1. When the compressor is running, the vibrations generated by the motor's operation and the piston's reciprocating motion will be transmitted downwards through the outdoor unit's main casing 1 to the frame, causing resonance. In response to these structural principles, the vibration-damping frame of the aforementioned air source heat pump outdoor unit is clamped between the extended mounting plate 11 and the first mounting beam 21 by an elastic interlayer 211, reducing the resonance in the main connection area between the outdoor unit's main casing 1 and the mounting frame 2. Furthermore, the corner elastic element 3 with three elastic baffles 31 on the second mounting beam 22 abuts against the four corners of the outdoor unit's main casing 1, suppressing the vertical vibration on each surface of the lower structure of the outdoor unit's main casing 1. In order to reduce the impact of the air source heat pump outdoor unit's vibration on the surface at the installation location, the support columns of the vibration-damping frame are equipped with elastic foot pads 41 as a structure to support the mounting frame 2, which are in contact with the surface at the installation location. In summary, the vibration damping frame has continuous vibration damping structures from top to bottom on the surface of the main body shell 1 of the outdoor unit to the installation location. Compared with the traditional rigid frame, it can more comprehensively reduce the resonance at the connection point, thereby achieving the beneficial effects of reducing noise and helping to protect the long-term stable operation of the core components inside the main body shell 1 of the outdoor unit.

[0034] When installing the vibration damping frame of the above-mentioned air source heat pump outdoor unit, first slide the first mounting beam 21 in the mounting waist-shaped hole 20a to the predetermined position of the outer mounting piece 11, so that the outdoor unit main body shell 1 is placed on the first mounting beam 21, and lock the outer mounting piece 11 to the beam waist-shaped hole 20b of the first mounting beam 21 with screws. Then move the second mounting beam 22 and the corner elastic member 3 installed on it, so that the corner elastic member 3 abuts against the four corners of the outdoor unit main body shell 1. Finally, use screws to limit the position of the corner elastic member 3 on the beam waist-shaped hole 20b of the second mounting beam 22.

[0035] Furthermore, the vibration damping frame of the air source heat pump outdoor unit also includes a supporting crossbeam 5, which is located between two first mounting crossbeams 21. The supporting crossbeam 5 is covered with an elastic pad 51 for supporting the outdoor unit main body shell 1. The supporting crossbeam 5 can support the bottom surface of the outdoor unit main body shell 1 between the two extended mounting pieces 11, so that the elastic pad 51 is sandwiched between the supporting crossbeam 5 and the outdoor unit main body shell 1, further expanding the range of vibration damping effect obtained on the bottom structure of the outdoor unit main body shell 1. When placing the outdoor unit main body shell 1 on the first mounting crossbeam 21, the outdoor unit main body shell 1 can be placed on the supporting crossbeam 5 first, and then the position of the first mounting crossbeam 21 can be adjusted to cooperate with the extended mounting pieces 11. When configuring the vibration damping frame, the heights of the supporting crossbeam 5, the first mounting crossbeam 21, and the second mounting crossbeam 22 should be selected according to the corresponding height of the bottom of the main body shell 1 of the outdoor unit, so that the elastic pad surface 51 of the supporting crossbeam 5, the elastic interlayer 211 of the first mounting crossbeam 21, and the elastic stop surface 31 of the corner elastic element 3 can all be in close contact with the main body shell 1 of the outdoor unit.

[0036] Elastic corner pieces 23 are provided at the corners between adjacent frame edges 201 of the mounting frame 2, and the mutually perpendicular edges of the elastic corner pieces 23 abut against different frame edges 201. The elastic corner pieces 23 help to reduce vibration between frame edges 201 and improve the strength of the connection structure.

[0037] In this embodiment, since the installation of a general frame also requires locking the frame to the frame mounting point with screws, in addition to the support column 4 with elastic foot pads 41, the bottom of the mounting frame 2 is also connected to the limiting column 6, which is distributed at the four corners of the mounting frame 2. The bottom of the limiting column 6 is provided with a metal washer 61 with a threaded hole, so as to lock it to the mounting surface through the limiting column 6, thereby fixing the vibration damping frame as a whole.

[0038] To improve the connection stability between the frame edge 201 with a long span and the limiting column 6 or supporting column 4, a reinforcing rod 62 that is obliquely connected to the mounting frame 2 is provided on the side of the limiting column 6 or supporting column 4.

[0039] On the premise of ensuring that the connection between the limiting column 6 and the mounting surface is sufficiently stable, the bottom of the metal gasket 61 is also provided with an elastic interlayer 211, the supporting column 4 is connected to its elastic foot pad 41 by a screw, and the screw of the supporting column 4 is fitted with a spring.

[0040] For example, the elastic stop surface 31 of the corner elastic member 3 and the elastic pad surface 51 of the supporting crossbeam 5 are any one of the following material layers: rubber material layer, polyurethane material layer and silicone material layer.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0042] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
