Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of heat pump units, specifically a heating air source heat pump unit. Background Technology
[0002] Air source heat pump units, as a highly efficient and energy-saving heating device, are widely used in residential, commercial, and industrial settings. Existing traditional air source heat pump units typically install the compressor pump inside the unit using a rigid mounting method, with the bottom of the compressor pump directly connected to the unit's base plate, or using simple elastic pads for partial vibration damping. This installation structure is relatively simple and can meet basic operational requirements, but it is difficult to effectively absorb the impact force generated by vibration when the compressor pump is running at high speeds. Furthermore, the bottom of the unit usually only uses anti-slip rubber pads or a single layer of elastic support for vibration isolation, meaning that vibration energy is still transmitted to the surrounding environment through the base plate when the unit is operating.
[0003] However, the aforementioned traditional technical solutions have obvious drawbacks:
[0004] Vibration transmission problem: Because the compressor pump generates a large vibration load during operation, the traditional rigid fixing method cannot effectively block the transmission of vibration to the outside of the unit, resulting in significant overall unit vibration and high operating noise, which is not conducive to improving the comfort of the user environment.
[0005] Limited vibration absorption effect: Although some technical solutions use elastic pads for support, their structure is simple and can only partially alleviate vertical vibration. They do not effectively limit or absorb the lateral movement or unbalanced vibration of the compressor pump, which can easily cause the compressor pump to deviate or produce abnormal noise during long-term operation.
[0006] Uneven stress distribution: Traditional vibration damping solutions cannot evenly distribute the vertical weight of the compressor pump. Local stress concentration can easily lead to aging and deformation of the damping pad material, which in turn affects the overall vibration damping performance and the long-term stability of the unit.
[0007] In view of this, we will study and improve the existing problems and provide a heating air source heat pump unit to solve the current problems. The aim is to solve the problems and improve the practical value through this technology. Summary of the Invention
[0008] The present invention aims to solve the technical problems existing in the prior art or related technologies.
[0009] The technical solution of this utility model is as follows:
[0010] A heating air source heat pump unit, comprising a heat pump casing and a compressor pump, characterized in that:
[0011] The heat pump casing is fixedly equipped with a shock-absorbing sleeve and flexible support feet on its inner side. The flexible support feet are fixed to the bottom surface of the compressor pump and are used to flexibly support the compressor pump, which can evenly distribute its vertical weight and vibration load. The shock-absorbing sleeve includes a fixed base and a ring base. The ring base is symmetrically arranged on the upper and lower surfaces of the fixed base and fits onto the outer surface of the compressor pump to limit the lateral movement of the compressor pump. The bottom surface of the heat pump casing is provided with vibration isolation pads to reduce the overall vibration transmission and operating noise of the unit.
[0012] Wherein: the surface of the elastic layer is set with a corrugated structure, and the inside of the corrugation is filled with foam material to further disperse the vibration transmission path; the support frame is made of metal or composite material and welded to the bottom surface of the heat pump box, and its structure is grid-like or honeycomb-like to improve the overall load-bearing capacity and reduce the deformation of the elastic layer.
[0013] The ring seat is an integrally formed structure. The ends of the first connecting strip and the second connecting strip are vertically connected, and there are several first connecting strips and second connecting strips, which are connected one-to-one. Several first connecting strips are arranged in parallel to each other.
[0014] The positioning block, the first connecting bar, and the second connecting bar are two sets, and are arranged symmetrically about the center of the floating collar.
[0015] The flexible support legs are rubber column structures, and are evenly distributed in a circumferential direction on the outer periphery of the compressor pump.
[0016] Detailed structure of the shock absorber sleeve: The ring sleeve includes a positioning block fixed to the surface of the fixed seat and a floating ring sleeved on the surface of the compressor pump; a second connecting bar is connected to one side of the positioning block, and a first connecting bar is connected to the surface of the floating ring; one end of the first connecting bar and the second connecting bar are connected to each other, and are arranged in a certain number corresponding to each other.
[0017] Detailed structure of the vibration isolation pad: The vibration isolation pad includes an elastic layer, a damping layer, a support frame, and an anti-slip bottom layer: The elastic layer is made of highly elastic rubber or polyurethane material to provide vibration isolation; the damping layer is set inside or on the surface of the elastic layer to absorb and attenuate vibration energy; the support frame is embedded inside the elastic layer to enhance the load-bearing capacity of the pad and maintain shape stability; the anti-slip bottom layer is set at the bottom of the pad, and increases the fixation effect when in contact with the ground through anti-slip textures or absorbent materials.
[0018] The beneficial effects achieved by this utility model are as follows:
[0019] 1. In this utility model, the ring seat of the shock-absorbing sleeve is horizontally limited by fitting the outer surface of the compressor pump. The flexible support foot can evenly distribute the vertical weight and vibration load of the compressor pump. Through the coordinated cooperation of the flexible support foot and the shock-absorbing sleeve, the vibration of the compressor pump during operation is effectively absorbed and attenuated, and the transmission of vibration to the casing and the outside world is significantly reduced.
[0020] 2. In this utility model, the vibration isolation pad foot, through the multi-layer structure design of elastic layer, damping layer and supporting frame, further reduces the overall vibration transmission of the unit, while reducing operating noise and improving the comfort of the user environment.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0029] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention. Example 1
[0030] like Figures 1 to 3 As shown, this utility model provides a heating air source heat pump unit, including a heat pump casing 100, a compressor pump 120, a shock-absorbing frame 200, and flexible support legs 300.
[0031] Heat pump casing 100: The heat pump casing is the external support structure of the equipment. Its bottom surface is equipped with several vibration isolation pads 110 to reduce the transmission of vibration during the operation of the unit. The compressor pump 120 and the vibration damping bracket 200 are fixedly installed inside the casing.
[0032] Compressor pump 120: The compressor pump is flexibly connected to the bottom of the chassis via a flexible support foot 300, and its outer periphery is fitted with a ring seat 220 in the shock-absorbing sleeve 200 to achieve the limiting and shock absorption of the compressor pump.
[0033] Vibration damping sleeve 200: The vibration damping sleeve includes a fixed base 210 and a ring sleeve 220. The ring sleeve 220 consists of a positioning block 221 and a floating ring 222: the positioning block 221 is connected to the floating ring 222 through a second connecting bar 224, the second connecting bar 224 has an arc-shaped structure and is fixed to the fixed base 210;
[0034] The floating ring 222 is sleeved on the outer periphery of the compressor pump 120, and its surface is connected with a number of first connecting strips 223. One end of the first connecting strips 223 and the second connecting strips 224 are connected to each other to realize the overall limiting and shock absorption function of the ring seat.
[0035] The ring sleeves are symmetrically arranged on both sides of the fixed seat 210 to ensure the stability of the compressor pump when subjected to lateral vibration.
[0036] Flexible support foot 300: The flexible support foot is made of highly elastic rubber and has a cylindrical structure. It is evenly distributed circumferentially on the bottom surface of the compressor pump 120 to flexibly support the compressor pump. The flexible support foot can evenly distribute the vertical weight and vibration load of the compressor pump and absorb the operating vibration of the compressor pump through its own elasticity.
[0037] Vibration isolation pad 110: adopts a multi-layer structure, including:
[0038] The elastic layer, made of highly elastic rubber, is used to provide primary vibration isolation.
[0039] The damping layer, located inside the elastic layer, is used to absorb the vibration energy generated during unit operation.
[0040] The supporting frame, embedded within the elastic layer, is made of metal to enhance the load-bearing capacity of the feet and maintain shape stability.
[0041] The non-slip bottom layer, located at the bottom of the pad, increases the fixation effect when in contact with the ground through non-slip textures or absorbent materials. Example 2
[0042] like Figure 4As shown, the design of the ring seat 220 is further optimized: The arrangement of the ring seat 220 is as follows: There are two sets of first connecting bars 223 and second connecting bars 224, which are arranged symmetrically about the center of the floating ring 222; several first connecting bars 223 are arranged in parallel to each other to ensure that the vibration transmission path is evenly distributed.
[0043] Integrated molding design: The ring seat 220 adopts an integrated molding structure, which reduces the number of parts, enhances the overall strength of the ring seat, and improves the convenience of installation and maintenance.
[0044] Synergistic effect of flexible support foot 300 and ring seat 220: When the compressor pump is subjected to vibration, the flexible support foot 300 absorbs vertical vibration through elasticity, while the ring seat 220 provides lateral restraint, forming a complete shock absorption system and further improving the operating stability of the compressor pump.
[0045] Installation and operation process:
[0046] Installation process: Fix the flexible support foot 300 to the bottom of the compressor pump 120, and fit the ring seat 220 of the shock-absorbing sleeve 200 onto the outer surface of the compressor pump 120; connect the compressor pump to the bottom of the heat pump casing 100, and ensure that the vibration isolation pad foot 110 is in uniform contact with the ground.
[0047] Operation process: After the compressor pump 120 starts, the flexible support foot 300 can absorb the vertical vibration generated during operation and evenly distribute its weight; the ring seat 220 suppresses the lateral swing of the compressor pump during operation through the limiting function of the first connecting bar 223 and the second connecting bar 224; the vibration isolation pad foot 110 further blocks the transmission of vibration to the heat pump box and the ground, while reducing operating noise.
[0048] Implementation Results: Through the above specific implementation methods, this utility model can significantly improve the vibration reduction performance and operational stability of heating air source heat pump units, effectively reduce vibration transmission and noise propagation, extend equipment service life, and provide a good user experience.
