Description

Technical Field

[0001] This utility model relates to the field of air conditioner outdoor unit technology, and more specifically, to an air conditioner outdoor unit. Background Technology

[0002] Currently, users have an increasingly strong demand for healthy air quality, and whether the oxygen content in the air meets the user's oxygen consumption requirements when the air conditioner is cooling or heating has become a key concern. Generally, oxygen-generating air conditioners are required to meet the user's oxygen consumption needs, and therefore are equipped with oxygen-generating components.

[0003] Existing oxygen generation modules typically include an oxygen adsorption tower. During operation, this tower is subjected to the combined effect of the compressed air pipe, resulting in significant vibration and thus considerable noise. To reduce noise in existing oxygen generation modules, the parts generating the most vibration can be placed in a sealed noise-reduction chamber.

[0004] However, if a sealed noise reduction cavity is used to reduce noise in the oxygen generation module, the oxygen generation module located in the sealed noise reduction cavity will experience high temperatures after long-term operation, resulting in poor heat dissipation and affecting the normal operation of the oxygen generation module.

[0077] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0078] like Figures 1 to 8 As shown, an embodiment of this utility model provides an air conditioner outdoor unit, which includes: an outdoor unit housing 10, a fan 20, a compressor 30, an oxygen generation module 40, and a noise reduction housing assembly 50. The outdoor unit housing 10 forms an installation cavity 11, and the fan 20 and the compressor 30 are both installed within the installation cavity 11. The oxygen generation module 40 and the noise reduction housing assembly 50 are disposed within the installation cavity 11. The noise reduction housing assembly 50 forms a noise reduction cavity 51, and the noise reduction housing assembly 50 is provided with heat dissipation holes 52 that communicate with both the noise reduction cavity 51 and the installation cavity 11. At least a portion of the oxygen generation module 40 is disposed within the noise reduction cavity 51. The oxygen generation module 40 is provided with a nitrogen exhaust outlet located in the noise reduction cavity 51, so that the nitrogen gas discharged through the nitrogen exhaust outlet forms a positive pressure in the noise reduction cavity 51, and under the action of the positive pressure, the gas in the noise reduction cavity 51 flows through the heat dissipation hole 52 to the negative pressure area formed by the rotation of the fan 20.

[0079] Specifically, at least a portion of the oxygen generating module 40 may be a structural part of the oxygen generating module 40 capable of generating vibration. Preferably, at least a portion of the oxygen generating module 40 may be a structural part of the oxygen generating module 40 capable of generating significant vibration.

[0080] The technical solution provided in this embodiment utilizes the high-pressure nitrogen generated during the operation of the oxygen generating module 40, combined with the negative pressure effect of the fan 20 chamber of the air conditioner outdoor unit. This creates natural convection between the high-pressure nitrogen and the negative pressure airflow, causing the airflow to automatically flow from the noise reduction chamber 51 to the negative pressure zone formed by the rotation of the fan 20. This accelerates heat exchange, achieving efficient heat dissipation. The above-mentioned effects are reflected in a significant reduction in the temperature of key components of the oxygen generating module 40, improved oxygen generation efficiency and stability, and extended equipment lifespan. Specifically, although the noise reduction chamber 51 in this embodiment is not a completely sealed cavity, it is mainly connected to the outside through the heat dissipation holes 52, thus forming a relatively sealed environment, facilitating effective noise reduction. Furthermore, the positive pressure of the nitrogen at the nitrogen outlet and the pressure difference of the negative pressure zone where the fan 20 rotates allow the hot air in the noise reduction chamber 51 to be effectively discharged through the heat dissipation holes 52, thereby effectively ensuring heat dissipation for the oxygen generating module 40. Therefore, the air conditioner outdoor unit provided in this embodiment can solve the technical problem in the prior art where the oxygen generating module has poor heat dissipation due to sealing and noise reduction of the oxygen generating component.

[0081] The outdoor unit of the air conditioner also includes a nitrogen exhaust silencer 60, which is located within the noise reduction chamber 51 and at the nitrogen exhaust outlet. In this way, the nitrogen exhaust silencer 60 effectively reduces the noise of the nitrogen gas flowing out of the nitrogen exhaust outlet, improving user comfort. The application scenarios are mainly for residential and commercial air conditioning systems, especially in environments with high requirements for indoor air quality.

[0082] Specifically, the oxygen generation module 40 in this embodiment includes an oxygen generation component 41, which includes an oxygen generation adsorption tower 411 and a molecular sieve. When the molecular sieve adsorbs nitrogen to saturation, the nitrogen needs to be desorbed by reducing the pressure and discharged through the nitrogen exhaust outlet. Specifically, continuous oxygen generation is achieved by controlling the adsorption and desorption states of the oxygen generation adsorption tower 411 through a reversing valve using pressure swing adsorption technology.

[0083] Specifically, the noise reduction housing 50 is positioned above the fan 20. This structural arrangement utilizes the space above the fan 20, reduces the impact on other components, optimizes the structural layout of the noise reduction housing 50, and improves the compactness of the structural layout.

[0084] Specifically, the heat dissipation hole 52 is located at the bottom of the noise reduction housing assembly 50. This allows the airflow in the noise reduction cavity 51 to flow smoothly through the heat dissipation hole 52 at the bottom to the negative pressure cavity formed by the rotation of the fan 20.

[0085] Specifically, the noise-reducing housing 50 is positioned above the fan 20, with the heat dissipation vents 52 located at the bottom of the housing 50. This utilizes the space above the fan 20 to reduce impact on other components, while the bottom heat dissipation vents 52 facilitate heat dissipation through the negative pressure effect within the fan 20 cavity. The effect is optimized space utilization within the outdoor unit of the air conditioner, improved heat dissipation efficiency, and reduced operating noise. The application scenario is in compact air conditioning systems, especially when multiple functional modules need to be integrated within a limited space.

[0086] In this embodiment, the mounting cavity 11 has a first connecting cavity 111, a second connecting cavity 112, and a third connecting cavity 113. The first connecting cavity 111 and the second connecting cavity 112 are separated and arranged side by side. The fan 20 is disposed in the first connecting cavity 111, the compressor 30 is disposed in the second connecting cavity 112, and the third connecting cavity 113 is located above the first connecting cavity 111 and the second connecting cavity 112. The oxygen generating module 40 is disposed in the third connecting cavity 113. The oxygen generating module 40 includes a first component and a second component connected to each other. The first component is disposed above the first connecting cavity 111, and the second component is disposed above the second connecting cavity 112. At least a portion of at least one of the first component and the second component is disposed in the noise reduction cavity 51. One of the first component and the second component is an oxygen generating component 41, and the other of the first component and the second component is an air compressor component 42. This structural design, by rationally allocating the positions of various components within the outdoor unit of the air conditioner, achieves efficient integration and collaborative operation of functional modules, optimizes the structural layout of each module within the outdoor unit, and improves the compactness of the layout. Furthermore, this layout also better integrates the communication relationship between the third connecting cavity 113 and the first connecting cavity 111, facilitating heat dissipation for the oxygen generating module 40. The corresponding implementation effect is improved overall performance of the outdoor unit, especially in oxygen generation and compressed air supply, achieving effective space utilization and reducing interference between components. Application scenarios include systems requiring simultaneous air conditioning and oxygen generation functions, such as high-end residences and hospital wards.

[0087] Specifically, the first component is an oxygen generating component 41, at least a portion of which is installed within the noise reduction cavity 51. The second component is an air compressor component 42, located outside the noise reduction cavity 51. This structural arrangement facilitates effective noise reduction and heat dissipation for at least a portion of the oxygen generating component 41, ensuring effective noise reduction and heat dissipation for at least a portion of the air compressor. Furthermore, by placing the air compressor component 42 outside the noise reduction cavity 51, and through the connection between the first connecting cavity 111 and the third connecting cavity 113, effective heat dissipation for the air compressor component 42 is facilitated. Additionally, this arrangement also prevents excessive heat within the noise reduction cavity 51, which could lead to poor heat dissipation.

[0088] Specifically, at least a portion of the heat dissipation hole 52 is located at the bottom of the noise reduction housing assembly 50 and directly above the first connecting cavity 111. This structural arrangement facilitates the transfer of heat from the noise reduction cavity 51 into the first connecting cavity 111 via the heat dissipation hole 52, thereby optimizing airflow and improving heat dissipation.

[0089] Specifically, the first component is an oxygen generating component 41, at least a portion of which is installed within the noise reduction cavity 51. The second component is an air compressor component 42, located outside the noise reduction cavity 51. At least a portion of the heat dissipation hole 52 is located at the bottom of the noise reduction housing assembly 50 and directly above the first connecting cavity 111. With this arrangement, the noisier air compressor component 42 is placed outside the noise reduction cavity 51, while the oxygen generating component 41 is placed inside. The sound insulation effect of the soundproof cover 54 and the bottom shell reduces noise pollution during operation. Simultaneously, the design of the heat dissipation hole 52 fully utilizes the negative pressure effect of the fan 20, enhancing the heat dissipation capacity of the oxygen generating component 41. The implementation effect is a significant reduction in the noise of the outdoor unit of the air conditioner, improved heat dissipation efficiency, and optimized user experience. The application scenario is in environments with strict requirements for noise and air quality, such as libraries and conference rooms.

[0090] Specifically, at least a portion of the heat dissipation through hole 52 is disposed opposite to the reversing valve of the oxygen generating component 41, so as to dissipate heat from the reversing valve at the high temperature part of the oxygen generating component 41 and improve the heat dissipation effect.

[0091] Specifically, the reversing valve of the oxygen generating component 41 can be used to control the switching between the adsorption and desorption states of the oxygen generating adsorption tower 411.

[0092] In this embodiment, the noise-reducing housing assembly 50 includes: a mounting base 53, a soundproof cover 54, and a sound-insulating component 55. At least a portion of the oxygen generating module 40 is mounted on the mounting base 53, and the mounting base 53 is provided with the heat dissipation holes 52. The soundproof cover 54 is mounted on the mounting base 53, and the soundproof cover 54 and the mounting base 53 form the noise-reducing cavity 51. The sound-insulating component 55 is disposed on the soundproof cover 54, and the sound-insulating component 55 is used to insulate the noise-reducing cavity 51. The sound-insulating component 55 is disposed on the side of the soundproof cover 54 near the noise-reducing cavity 51 and / or the side of the soundproof cover 54 away from the noise-reducing cavity 51. With this structural arrangement, the combination of the soundproof cover 54 and the sound-insulating component 55 forms a closed noise-reducing cavity 51, effectively isolating the noise generated by the oxygen generating module 40 during operation. The effect is a significant reduction in the operating noise of the air conditioner outdoor unit and an improvement in the quietness performance of the equipment. The application scenarios are in environments with high requirements for noise control, such as nighttime use and residential areas.

[0093] Specifically, the sound insulation component 55 is sound insulation cotton, which improves the noise reduction effect on the noise reduction cavity 51. Specifically, the sound insulation cotton utilizes its sound absorption properties to absorb and weaken the propagation of sound waves, thereby achieving the purpose of noise reduction.

[0094] Specifically, the fan 20 includes a motor 21 and fan blades connected to the drive. The motor 21 is fixedly installed in the mounting cavity 11, and the mounting base 53 is supported on the motor 21. The heat dissipation hole 52 is offset from the motor 21. The mounting base being supported on the motor 21 improves the stability of the mounting base. The offset arrangement of the heat dissipation hole 52 from the motor 21 prevents heat from the heat dissipation hole 52 from being directly blown to the motor 21, allowing the heat from the heat dissipation hole 52 to bypass the motor 21 and be blown into the first connecting cavity 111, thus facilitating effective heat dissipation and improving the heat dissipation effect.

[0095] In this embodiment, the mounting base 53 extends out from one side of the soundproof cover 54. The oxygen generation module 40 includes an oxygen generation adsorption tower 411 and an electrical box 412 electrically connected. The oxygen generation adsorption tower 411 is disposed inside the noise reduction cavity 51, and the electrical box 412 is mounted on the mounting base 53 and located outside the noise reduction cavity 51. This structural arrangement facilitates the maintenance and replacement of the electrical box 412 component and avoids the situation where excessive heat cannot be effectively dissipated due to the electrical box 412 component being located inside the noise reduction cavity 51.

[0096] Specifically, the outdoor unit of the air conditioner also includes a heat dissipation plate 70, which is connected to the mounting base 53 and located on the side of the mounting base 53 closer to the fan 20. The heat dissipation plate 70 has ventilation holes 71 penetrating it. The mounting base 53 is mounted on the heat dissipation plate 70, with at least a portion of the mounting base 53 spaced apart from the heat dissipation plate 70 to form a heat dissipation gap 533. Both the ventilation holes 71 and the heat dissipation through-holes 52 communicate with the heat dissipation gap 533, allowing airflow at the ventilation holes 71 to pass through the heat dissipation gap 533 and then exit through the heat dissipation through-holes 52. This structural arrangement, utilizing the cooperation of the heat dissipation plate 70 and the heat dissipation gap 533, effectively enhances airflow and improves heat dissipation efficiency. The corresponding effect is that the oxygen generation module 40 can maintain good heat dissipation even during prolonged operation, avoiding performance degradation due to overheating. This is particularly suitable for use under high temperature or long-term operation conditions, such as air conditioning use during peak summer hours, or in environments with dense heat sources.

[0097] In this embodiment, the mounting base 53 includes a main body 531 and supporting ribs 532. The main body 531 is provided with a limiting space 5311 for adapting to at least a portion of the oxygen generating module 40, and at least a portion of the oxygen generating module 40 is installed within the limiting space 5311. The supporting ribs 532 are disposed on the side of the main body 531 near the heat dissipation plate 70, and the end of the supporting ribs 532 away from the main body 531 is supported on the heat dissipation plate 70, so that at least a portion of the main body 531 is spaced apart from the heat dissipation plate 70 to form the heat dissipation gap 533. With this structural arrangement, the limiting space 5311 and the supporting ribs 532 achieve stable installation and effective heat dissipation of the oxygen generating module 40, and the supporting ribs 532 ensure the formation of the heat dissipation gap 533. The implementation effect is to improve the operational stability and heat dissipation efficiency of the oxygen generating module 40 and reduce maintenance costs. The application scenario is in air conditioning systems that need to be frequently started and stopped, such as air conditioning systems in public places like shopping malls and cinemas.

[0098] Specifically, at least one of the heat sink 70 and the mounting base 53 is made of a metal material. This utilizes the excellent thermal conductivity of metal to accelerate heat conduction and dissipation.

[0099] Specifically, the height of the heat dissipation gap 533 is h, where h > 8mm. This structural design ensures that the heat dissipation gap 533 has sufficient height to facilitate adequate heat dissipation, guarantees sufficient space for smooth airflow, and improves heat dissipation efficiency.

[0100] Specifically, there are multiple heat dissipation through holes 52, which are spaced apart. There are also multiple ventilation holes 71, which are also spaced apart. A portion of each ventilation hole 71 is positioned opposite to the heat dissipation through holes 52, while another portion is offset from them. This structural arrangement aims to create an effective airflow path for the heat dissipation through holes 52 and ventilation holes 71, promoting uniform heat dissipation. The effect is improved heat dissipation capacity and operating efficiency of the entire system, while reducing energy consumption. The application scenario is in environments requiring efficient heat dissipation, such as data centers and laboratories.

[0101] In this embodiment, the oxygen generating component 41 has an installation height extending along the height direction of the noise reduction cavity 51. The oxygen generating component 41 also has an installation width and an installation length, with any two of the installation height, installation width, and installation length being vertically arranged; wherein the installation height is less than the installation width, and the installation length is less than the installation length. This structural arrangement allows the oxygen generating component 41 to be installed horizontally, reducing its installation height and adjusting its installation dimensions to better suit the internal space layout of the air conditioner outdoor unit, thus reducing interference with other components. The implementation effect is optimized space utilization inside the air conditioner outdoor unit, improving the integration and operating efficiency of the oxygen generating module 40. The application scenario is in air conditioning systems with limited space.

[0102] Specifically, a first interlocking groove 541 is recessed on one side of the soundproof cover 54. This first interlocking groove 541 is located outside the noise reduction cavity 51. The portion of the inner wall of the soundproof cover 54 opposite to the first interlocking groove 541 abuts against the first end of the oxygen adsorption tower 411. The first interlocking groove 541 on the soundproof cover 54 enables precise positioning and fixation of one end of the oxygen adsorption tower 411, while also reducing noise propagation. The effect is improved installation accuracy and stability of the oxygen adsorption tower 411, and reduced operating noise. The application scenario is in environments requiring precise noise and vibration control, such as hospitals and schools.

[0103] Specifically, a second interlocking groove 542 is recessed on the other side of the soundproof cover 54. This second interlocking groove 542 is located outside the noise reduction cavity 51. The portion of the inner wall of the soundproof cover 54 opposite to the second interlocking groove 542 abuts against the second end of the oxygen adsorption tower 411. The first interlocking groove 541 on the soundproof cover 54 enables precise positioning and fixation of one end of the oxygen adsorption tower 411, while the structure of the second interlocking groove 542 reduces noise propagation. The effect is improved installation accuracy and stability of the oxygen adsorption tower 411, and reduced operating noise. The application scenario is in environments requiring precise noise and vibration control, such as hospitals and schools.

[0104] Specifically, in this design, the oxygen-generating adsorption tower 411 is installed horizontally, with a mounting base 53 having heat dissipation holes 52 at the bottom. A handle structure (corresponding to the first snap-fit ​​groove 541 and the second snap-fit ​​groove 542) and a soundproof cover 54 with attached sound-absorbing cotton are designed on the upper side of the oxygen-generating adsorption tower 411. The upper surface of the mounting base 53 is designed to conform to the lower surface of the oxygen-generating adsorption tower 411, limiting its front and rear movement. The inner side of the handle of the soundproof cover 54 is designed to conform to the end cap surface of the oxygen-generating adsorption tower 411, limiting its left and right movement. The oxygen-generating adsorption tower 411 is fixed, and its assembly size is minimized to allow space for the electrical box 412 and piping. The mounting base 53 and the soundproof cover 54 are circumferentially sealed. The mounting base 53 is designed with heat dissipation holes near the reversing valve area and is connected to the negative pressure zone of the bottom air conditioner outdoor unit fan 20 cavity (corresponding to the first connecting cavity 111). High-pressure nitrogen and negative pressure effect are used to dissipate heat from the oxygen adsorption tower 411.

[0105] In the above embodiment, considering the small installation space of the oxygen-generating air conditioner, the oxygen-generating adsorption tower 411 is installed horizontally, and the oxygen-generating adsorption tower 411 is fixed by the structural design of the mounting base 53 and the sound insulation cover 54 to reduce operating vibration. At the same time, the high-pressure nitrogen exhaust gas and the negative pressure of the air conditioner fan 20 chamber are used for heat dissipation to solve the problem of valve body temperature rise.

[0106] Specifically, the upper surface of the mounting base 53 is designed to mimic the bottom surface of the oxygen adsorption tower 411. Furthermore, to effectively position and install the air compressor component 42, the outdoor unit also includes a positioning housing assembly for positioning and installing the air compressor component 42. The positioning housing assembly is connected to the outdoor unit housing 10, and its upper surface is configured as a double-arc structure adapted to the air compressor component 42 to restrict the forward and backward movement of the air compressor component 42.

[0107] Specifically, a sound insulation cotton pasting area is designed inside the sound insulation cover 54 to reduce the discontinuous noise problem during the operation of the oxygen generation adsorption tower 411; handles are designed at both ends of the sound insulation cover (corresponding to the first snap-fit ​​groove 541 and the second snap-fit ​​groove 542), which contact and limit the end cap of the oxygen generation adsorption tower 411 to restrict the left and right and up and down displacement of the oxygen generation adsorption tower 411.

[0108] Specifically, the heat sink 70 can be a sheet metal support base with insect-proof heat dissipation holes, and the heat sink 70 is installed and fixed to the outer casing of the air conditioner outdoor unit.

[0109] like Figure 1 The diagram shows the overall installation effect of the outdoor unit of the air conditioner (excluding the top cover). The outdoor unit casing 10 includes a top cover located at the top. The oxygen adsorption tower 411 is installed on the left side of the outdoor unit and above the first connecting cavity 111 where the fan 20 is located. The heat dissipation plate 70 is supported by the bracket of the motor 21 and the sheet metal casing. At the same time, a mounting base 53 is provided at the bottom of the oxygen adsorption tower 411. The mounting base 53 maintains a certain distance (>8mm) from the heat dissipation plate 70, forming a ventilation and heat dissipation layer (i.e., heat dissipation gap 533). The heat dissipation through-hole 52 of the mounting base 53 communicates with the air layer and is connected to the first connecting cavity 111 of the outdoor unit through the ventilation holes 71 on the heat dissipation plate 70.

[0110] like Figure 9 The diagram shows the wind speed distribution during the operation of the outdoor unit of the air conditioner. The oxygen adsorption tower 411 includes a reversing valve that is sensitive to temperature and has high requirements for temperature rise. The first connecting cavity 111 below the area where the reversing valve is located is a low-speed area (i.e., a negative pressure area). The heat generated by the oxygen adsorption tower 411 can be dissipated through the high-pressure nitrogen gas generated by the nitrogen exhaust silencer 60 during the oxygen production process, combined with the semi-closed sealed cavity effect formed by the structure, through the heat dissipation holes and the channel formed by the heat dissipation layer, into the first connecting cavity 111 of the outdoor unit, and then blown out through the first connecting cavity 111 for heat dissipation.

[0111] As can be seen from the above description, the above embodiments of this utility model achieve the following technical effects: they solve the technical problems of large vibration caused by the compressed air pipe in the oxygen adsorption tower, limited installation space, and poor overall heat dissipation in the prior art.

[0112] By horizontally installing the oxygen-generating adsorption tower assembly, combined with the structural design of the mounting base and soundproof enclosure, vibration during operation is effectively reduced, while assembly dimensions are minimized, providing more space for the electrical box and piping. The negative pressure zone created by the high-pressure nitrogen purging gas and the air conditioning fan guides the heat dissipation airflow, resolving the temperature rise issue caused by valves and other components within the oxygen-generating unit, thus improving the operating efficiency and stability of the oxygen-generating module.

[0113] This solution not only optimizes the internal layout of the outdoor unit of the air conditioner, but also improves the reliability of the oxygen generation function and the user experience. It is particularly suitable for residential or commercial air conditioning systems with limited space, providing strong technical support for improving air quality.

[0114] The principle of this design is to combine the physical characteristics of the oxygen-generating adsorption tower components with the working environment of the air conditioner outdoor unit. It employs horizontal installation and a special heat dissipation strategy to adapt to limited installation space and solve the heat dissipation problem of key components. The implementation results in the efficient integration and stable operation of the oxygen generation function, while optimizing the overall layout of the air conditioner outdoor unit, improving space utilization and user experience. Application scenarios include various environments requiring increased indoor oxygen levels, such as gyms, yoga rooms, and nursing homes, where the advantages of this solution are particularly evident in situations with limited space. In operation, when the air conditioner is in oxygen generation mode, the oxygen-generating adsorption tower components begin to work. Simultaneously, the nitrogen exhaust silencer generates high-pressure nitrogen gas, which, combined with the negative pressure effect of the air conditioner fan cavity, promotes heat exchange within the noise reduction cavity, ensuring the normal operation of the oxygen generation module.
