[0062] Background

[0063] Currently, the fresh air devices on the market can only circulate indoor and outdoor air, but the oxygen concentration of indoor air cannot meet the requirements. Oxygen production devices can increase the indoor oxygen concentration and increase breathing comfort, and oxygen-producing air conditioners came into being.

[0064] The oxygen production device is generally integrated inside the outdoor unit of the air conditioner. The oxygen production device mainly includes an air compressor and an oxygen production tower. The main function of the air compressor is to compress the air in the outdoor environment. The compressed high-pressure air enters the oxygen production tower. The main function of the oxygen production tower is to adsorb the air entering the oxygen production tower, absorbing nitrogen, carbon dioxide and other waste gases in the air, leaving only oxygen and transporting it into the room, thereby increasing the oxygen concentration of the indoor air.

[0065] However, the oxygen-generating air conditioner in the prior art has the following disadvantages and shortcomings: the oxygen-generating component is a whole module arranged on the air conditioner outdoor unit, which makes it inconvenient to inspect and repair the oxygen-generating component and the electrical components inside the outdoor unit.

[0066] Based on this, Figure 1-Figure 11 As shown, the first aspect of the embodiment of the present application provides an air conditioner outdoor unit, comprising:

[0067] An external machine body 100, wherein an internal portion of the external machine body 100 is formed with an internal chamber and a top opening communicating with the internal chamber is formed on the top;

[0068] The oxygen production component 200 includes an oxygen production shell 201 disposed at a top opening, and an oxygen production tower module 202 and an air compressor module 203 disposed inside the oxygen production shell 201. The oxygen production shell 201 includes a bottom shell 2011 covering a portion of the top opening;

[0069] One of the oxygen production tower module 202 and the air compressor module 203 is installed on the bottom shell 2011 , and the other is installed at the top opening not covered by the bottom shell 2011 .

[0070] In the embodiment of the present application, the oxygen production component 200 is designed to include an oxygen production tower module 202 and an air compressor module 203. This modular design facilitates the installation, disassembly and maintenance of the components. When the oxygen production tower or the air compressor needs to be repaired or replaced, it can be operated separately, which improves the convenience and efficiency of maintenance. At the same time, by setting a bottom shell 2011 that only covers part of the top opening of the external machine, and setting the air compressor module or the oxygen production tower module at the top opening of the external machine not covered by the bottom shell 2011, when the oxygen production tower module 202 or the air compressor module 203 at the top opening of the external machine not covered by the bottom shell 2011 is removed, the electrical components inside the external machine can be exposed, so that it is convenient for maintenance personnel to repair it.

[0071] Further, in some possible implementations, the oxygen tower module 202 is installed on the bottom shell 2011, and the air compressor module 203 is installed at the top opening not covered by the bottom shell 2011;

[0072] The machine compartment inside the external machine body 100 includes a compressor installation compartment for accommodating the compressor 300 and the external machine electrical box 400 , and the compressor installation compartment corresponds to the top opening not covered by the bottom shell 2011 .

[0073] In the embodiment of the present application, since the compressor installation compartment corresponds to the top opening not covered by the bottom shell, when the compressor or the external unit electrical box needs to be maintained, it can be operated directly through the top opening without disassembling the oxygen production component, which greatly improves the convenience of maintenance. Through the design that is easy to maintain, potential problems with the compressor and the electrical box can be discovered and handled in a timely manner, reducing safety risks caused by equipment failures and enhancing the safety of the entire air-conditioning system.

[0074] Further, in some possible implementations, a portion of the air compressor module 203 is embedded in the compressor installation compartment, and another portion is disposed in the oxygen production housing 201;

[0075] One circumferential side of the air compressor module 203 is connected to the bottom shell 2011 of the oxygen production shell 201 , and the other circumferential side is connected to the side shell of the oxygen production shell 201 .

[0076] A part of the air compressor module 203 in the embodiment of the present application is embedded in the compressor installation compartment, and the other part is arranged in the oxygen production shell 201. This design enables the air compressor module 203 to make full use of the space inside the air conditioner outdoor unit, realize a compact layout, and improve space utilization. One side of the circumferential direction of the air compressor module 203 is connected to the bottom shell of the oxygen production shell 201, and the other side is connected to the side shell of the oxygen production shell 201. This design provides additional support and stability, which is convenient for the installation of the air compressor module 203.

[0077] Furthermore, in some possible implementations, the air compressor module 203 is also equipped with a radiator 2031 , and the radiator 2031 is used to reduce the temperature of the pressurized air of the air compressor module 203 .

[0078] In the embodiment of the present application, the temperature of the air after the air compressor is pressurized can be effectively reduced by adding a radiator 2031 to the air compressor module 203. Since the molecular sieve in the oxygen production tower works more efficiently at a lower temperature, this design helps to improve the oxygen production efficiency.

[0079] Further, in some possible implementations, the radiator 2031 is equipped with a cooling fan 2032, and the external machine body 100 is equipped with an external machine fan 101;

[0080] The external machine body 100 is also provided with an air inlet 102 connected to the machine compartment, and the air compressor module 203 is provided with a heat dissipation air inlet 20332 connected to the machine compartment, and a heat dissipation air outlet 20351 connected to the inside of the oxygen production shell 201;

[0081] When the cooling fan 2032 and the external unit fan 101 are in operation, external air flow can be sucked into the cabin through the air inlet 102. A portion of the air flow sucked into the cabin can dissipate heat to the condenser inside the external unit under the action of the external unit fan 101. Another portion of the air flow sucked into the cabin can dissipate heat to the radiator 2031 of the air compressor module 203 through the cooling air inlet 20332 under the action of the cooling fan 2032, and be discharged into the oxygen production casing 201 through the cooling air outlet 20351.

[0082] In the embodiment of the present application, by adding a cooling fan 2032 to the radiator, the radiator 2031 of the air compressor module 203 can be actively forced to dissipate heat, which is more efficient than the natural convection heat dissipation method and can more quickly reduce the air temperature of the air compressor module 203 after pressurization. The coordinated work of the outdoor fan and the cooling fan enables the external airflow to effectively dissipate the heat of the condenser and the radiator of the air compressor module, thereby improving the heat dissipation performance of the entire air conditioner outdoor unit. By designing a special air inlet, heat dissipation air inlet and heat dissipation air outlet, the flow of airflow is made more orderly, the airflow management in the cabin is optimized, and the heat dissipation efficiency is improved.

[0083] Further, in some possible implementations, the bottom shell 2011 of the oxygen generator housing 201 and the external machine fan 101 are arranged correspondingly in the height direction of the external machine body 100, and the bottom shell 2011 is further provided with a bottom shell heat dissipation channel 20111 connecting the machine compartment and the interior of the oxygen generator housing 201;

[0084] The airflow discharged into the oxygen generator housing 201 through the heat dissipation outlet 20351 can enter the machine compartment through the bottom shell heat dissipation channel 20111, and is discharged to the outside of the external machine body 100 under the action of the external machine fan 101 inside the machine compartment.

[0085] In the embodiment of the present application, by providing a bottom shell heat dissipation channel 20111 on the bottom shell 2011 of the oxygen generator housing 201, the hot air flow after heat exchange with the radiator 2031 in the oxygen generator housing 201 can directly enter the interior of the machine compartment, and be discharged to the outside of the external unit body 100 under the action of the external unit fan 101, without the need to provide a separate air duct to discharge the hot air flow in the oxygen generator housing 201. That is, through the design of the bottom shell heat dissipation channel 20111, the negative pressure generated by the operation of the external unit fan 101 can be more effectively used to discharge the air flow in the oxygen generator housing 201 to the outside of the outdoor unit.

[0086] Further, in some possible implementations, the air compressor module 203 includes an air compressor base 2033, an air compressor 2034, an air compressor cover 2035, an air compressor capacitor 2038, a radiator 2031 and a cooling fan 2032, the air compressor base 2033 is recessed with a mounting groove 20331, the air compressor cover 2035 is disposed at the mounting groove 20331 position of the air compressor base 2033 and defines an air compressor installation cavity between the mounting groove 20331, the air compressor 2034 is installed in the air compressor installation cavity, and the air compressor base 2033 is installed with an air compressor capacitor 2038, a radiator 2031 and a cooling fan 2032;

[0087] The air compressor base 2033 is provided with a heat dissipation air inlet 20332 connected to the air compressor installation cavity, the air compressor cover 2035 is provided with a heat dissipation air outlet 20351 connected to the air compressor installation cavity, the air inlet end of the cooling fan 2032 corresponds to the heat dissipation air outlet 20351, and the air outlet end corresponds to the radiator 2031.

[0088] The air compressor module 203 in the embodiment of the present application integrates multiple components such as the air compressor base 2033, the air compressor 2034, the air compressor cover 2035, the air compressor capacitor 2036, the radiator 2031 and the cooling fan 2032. This integrated design makes the entire module compact and easy to install and maintain. The heat dissipation air inlet 20332 on the air compressor base 2033 and the heat dissipation air outlet 20351 on the air compressor cover 2035 are designed to cooperate with the use of the cooling fan 2032 to form an effective heat dissipation airflow channel, which helps to quickly discharge the heat generated by the air compressor and reduce the operating temperature of the air compressor. The mounting slot 20331 design of the air compressor base 2033 allows the air compressor 2034 and other components to be compactly installed together, thereby improving the utilization rate of the internal space of the air conditioner outdoor unit. The integrated design and effective heat dissipation of the air compressor module 203 help maintain the stable operation of the air compressor 2034, reduce the performance degradation or failure caused by temperature fluctuations, and improve the stability of the entire air conditioning system.

[0089] Further, in some possible implementations, an air compressor assembly column 20333 is provided in the installation groove 20331 of the air compressor base 2033, and the air compressor 2034 is installed in the installation groove 20331 through the air compressor assembly column 20333;

[0090] The air compressor module 203 further includes a shock absorbing spring 2036 and a rubber pad 2037. The shock absorbing spring 2036 is mounted on the air compressor assembly column 20333. The rubber pad 2037 is mounted on the base of the air compressor 2034. When the air compressor 2034 is installed in the installation groove 20331 through the air compressor assembly column 20333, the rubber pad 2037 on the base of the air compressor 2034 and the shock absorbing spring 2036 cooperate together.

[0091] The air compressor base 2033 is also provided with a reinforcing structure with reinforcing ribs, on which are arranged pipe grooves 20334 for pipe routing and / or wiring grooves 20335 for wiring, and the air compressor cover 2035 is provided with pipe openings 20352 for pipe routing and sound insulation cotton for sound insulation.

[0092] In the embodiment of the present application, by setting the air compressor assembly column 20333 in the installation groove 20331 of the air compressor base 2033, and using the shock-absorbing spring 2036 and the rubber pad 2037, the vibration of the air compressor 2034 during operation can be effectively reduced, and the stability and service life of the entire system can be improved. The use of the shock-absorbing spring 2036 and the rubber pad 2037 not only reduces the vibration, but also helps to reduce the noise generated by the operation of the air compressor 2034, and improves the noise level of the surrounding environment. The air compressor base 2033 is provided with a reinforcement structure with reinforcing ribs, which enhances the structural strength of the base and enables it to better withstand the pressure and vibration generated when the air compressor is running. The design of the pipe groove and the wiring groove makes the layout of the pipelines and wires more orderly, convenient for installation and maintenance, and also reduces the risk of damage to the pipelines and wires. The orderly pipeline layout and the hidden wiring design make the appearance of the entire air compressor module more neat and beautiful. The sound insulation cotton pasted in the air compressor cover helps to further reduce the noise when the air compressor is running and improve the sound insulation effect of the equipment.

[0093] Further, in some possible implementations, the bottom of the air compressor module 203 is embedded in the external machine body 100, and the bottom of the air compressor module 203 is disposed close to the electrical box 400 in the external machine body 100;

[0094] The oxygen tower module 202 includes an oxygen outlet and a nitrogen outlet.

The reversing four-way valve 2023 is connected to the oxygen production tower 2024 through a pipeline to pass the pressurized air of the air compressor module 203 to the oxygen production tower 2024.

[0098] The oxygen tower module in the embodiment of the present application is composed of a bottom support, a main board, a reversing four-way valve, the oxygen tower itself and a top cover. This modular design makes the structure of the oxygen tower module clearer and convenient for assembly, maintenance and replacement. The oxygen production main board controls the reversing of the reversing four-way valve so that the oxygen production tower can work in turns, which can improve the oxygen production efficiency and extend the service life of the oxygen production tower. Through the precise control of the reversing four-way valve by the oxygen production main board, the stable operation of the oxygen production tower module can be ensured, and the downtime caused by improper operation or equipment failure can be reduced.

The bottom of the oxygen production tower module base 2021 is designed with base heat dissipation grooves around the bottom, and the base heat dissipation grooves are connected to the interior of the external unit body 100.

[0101] In the embodiment of the present application, a special placement groove is provided on the bottom bracket of the oxygen tower module for placing the oxygen tower, the reversing four-way valve and the oxygen production mainboard. This design makes the internal component layout more reasonable and optimizes the space utilization. Since each component has a special placement groove, this makes assembly and maintenance easier, reduces the possibility of assembly errors, and improves maintenance efficiency. The reversing four-way valve and the oxygen tower are connected by a hose. This design improves the flexibility of the system and facilitates the replacement or movement of components when necessary. And the hose connection can reduce the vibration and noise generated by the reversing four-way valve and the oxygen tower during operation, and improve the comfort of the surrounding environment. The bottom bracket heat dissipation groove designed around the bottom of the oxygen tower module bottom bracket is connected to the inside of the external unit body, which helps to quickly dissipate heat, improve heat dissipation efficiency, and extend the life of the equipment. Good heat dissipation design helps to maintain the stable operation of the oxygen tower module, reduce performance degradation or failure caused by overheating, and improve the stability of the entire air conditioner outdoor unit.

[0102] Further, in some possible embodiments, a bottom shell heat dissipation channel 20111 connected to the interior of the external machine body 100 is provided on the bottom shell 2011 of the oxygen-generating housing 201, and the bottom shell heat dissipation channel 20111 includes a bottom shell connecting groove 201111 and a bottom shell heat dissipation groove 201112. An external machine fan 101 is provided inside the external machine body 100, and the bottom shell connecting groove 201111 and the bottom shell heat dissipation groove 201112 correspond to the external machine fan 101 up and down.

[0103] In the embodiment of the present application, by providing a bottom shell heat dissipation channel on the bottom shell of the oxygen generator shell, including a bottom shell connecting groove and a bottom shell heat dissipation groove, heat can be more effectively transferred from the inside of the oxygen generator shell to the inside of the external unit body, thereby enhancing the heat dissipation efficiency. The design of the bottom shell connecting groove and the bottom shell heat dissipation groove makes the airflow management more orderly, helps to improve the efficiency of air flow, and thus improves the heat dissipation effect. Effective heat dissipation can prevent performance degradation or failure due to overheating, and improve the stability and reliability of the entire air-conditioning outdoor unit. The corresponding design of the external unit fan and the bottom shell heat dissipation channel can reduce turbulence, reduce the noise caused by airflow, and improve the quietness of operation. By optimizing the design of the heat dissipation channel, the energy required for additional consumption due to insufficient heat dissipation can be reduced, thereby improving the energy efficiency of the system.

This design makes the structure of the entire oxygen production shell more compact and stable. The defined accommodation space can maximize the use of the space inside the external unit body, improve space utilization, and allow the air conditioner outdoor unit to integrate more functional modules. The side shell and top shell of the oxygen production shell provide physical protection for the oxygen tower module and the air compressor module to prevent external environment such as rain, dust, etc. from damaging the internal components.

After removing the top cover and the right handle, the mainboard of the electrical box in the external machine body 100 can be repaired and replaced by removing the air compressor module 203.

[0109] Reference Fig.10 and Fig.11 The heat dissipation bottom plate is designed with a bottom shell connecting groove 201111 and multiple bottom shell heat dissipation grooves 201112. These grooves enable the oxygen production component 200 to be connected to the air duct inside the external machine body 100, and the negative pressure generated by the rotation of the fan 101 inside and outside the air duct drives the air flow inside the oxygen production component 200 to dissipate heat. Fig.11 As shown, the bottom shell connecting groove 201111 and the multiple bottom shell heat dissipation grooves 201112 are located on the left side to prevent water from the internal air duct of the external unit body 100 from being thrown up when it rains and causing adverse effects on the oxygen production component 200. The heat dissipation base plate is also used to place the oxygen production tower module 202.

[0110] Reference Figure 8 and Fig. 9The oxygen tower module 202 is composed of an oxygen tower module base 2021, an oxygen main board 2022, a reversing four-way valve 2023, an oxygen tower 2024, and an oxygen tower module top cover 2025.

The oxygen main board 2022 is fixed in the oxygen tower module base 2021 with screws; the reversing four-way valve 2023 is used to continuously pass the high-pressure air after heat dissipation to the two towers of the oxygen tower 2024 respectively. The oxygen tower 2024 is used for adsorption oxygen production, and is connected to the reversing four-way valve 2023 by a hose, and the high-pressure air from the reversing four-way valve 2023 is adsorbed to produce oxygen, while nitrogen and other non-oxygen gases are discharged. The oxygen tower 2024 is placed in the oxygen tower module bottom bracket 2021 and fixed with screws; the oxygen tower module top cover 2025 is used to seal the oxygen tower module 202 to prevent the influence of the external high temperature and high humidity environment, ensure the working environment of the oxygen tower 2024, and extend the service life. The oxygen tower 2024 can be replaced by removing the external machine top cover and the oxygen tower module top cover 2025, which is convenient for the maintenance and replacement of the oxygen tower 2024.

[0111] Reference Fig. 9 The oxygen tower module base 2021 is designed with an oxygen tower placement slot, a reversing four-way valve placement slot, and an oxygen mainboard placement slot, which are used to place and assemble the oxygen tower 2024, the reversing four-way valve 2023, and the oxygen mainboard 2022. The reversing four-way valve 2023 and the oxygen tower 2024 are not fixedly connected, but connected by a hose, which is convenient for the reasonable placement of the oxygen tower module 202, and the replacement of the reversing four-way valve 2023 can be saved when the oxygen tower 2024 is replaced later. Heat dissipation slots are designed around the bottom of the oxygen tower module base 2021, so that the airflow in the oxygen production component 200 and the airflow in the air duct of the external machine body 100 can be effectively convectively exchanged, thereby dissipating heat, and will not be affected by rain, dust, etc. in the air duct of the external machine body 100.

[0112] See attached Figure 7The air compressor module 203 is composed of an air compressor base 2033, four shock-absorbing springs 2036, four rubber pads 2037, an air compressor 2034, an air compressor cover 2035, an air compressor capacitor 2038, a cooling fan 2032, and a radiator 2031. The shock-absorbing spring 2036 is assembled on the air compressor assembly column 20333 of the air compressor base 2033 by using an axial hole, and is used to reduce the shock of the air compressor 2034; the rubber pad 2037 is assembled on the air compressor base foot by using a buckle to support the shock-absorbing air compressor 2034; the air compressor 2034 and the rubber pad 2037 are assembled on the air compressor assembly column 20333 of the air compressor base 2033 by using an axial hole; sound insulation cotton is pasted in the air compressor cover 2035 to soundproof the air compressor 2034, and the air compressor cover 2035 covers the air compressor 2034 and is fixed on the air compressor base 2033 by screws; the air compressor capacitor 2038 is assembled on the air compressor base 203 3 is fixed with the reinforcement rib positioning screws to start the air compressor 2034; the cooling fan 2032 is fixed on the air compressor cover 2035 with screws to dissipate heat and cool the air compressor cover 2035, so that the ambient temperature when the air compressor 2034 is running is suitable, and the service life of the air compressor 2034 is extended; the radiator 2032 is fixed with the reinforcement rib positioning screws of the air compressor base 2033. The temperature of the pressurized air of the air compressor 2034 is very high, up to more than ninety degrees Celsius. Directly passing it into the oxygen tower 2024 will seriously affect the oxygen production efficiency and service life of the oxygen tower 2024, so the high-pressure air needs to be cooled before passing it into the oxygen tower 2024.

[0113] See attached Figure 7 The air compressor cover 2035 is used to cover the sealed air compressor 2034, and a sponge is pasted inside for sound insulation. A heat dissipation outlet 20351 is designed on the side to dissipate the heat generated by the air compressor 2034, and a pipe opening 20352 is designed to facilitate the installation of the air pipe.

[0114] See attached Figure 4 The filtered air enters the oxygen production component 200 from the air port of the air nozzle, and is passed into the air compressor 2034 for pressurization. The pressurized air passes through the radiator 2032 for heat dissipation and cooling, and then enters the reversing four-way valve 2023, which controls the reversing to pass the high-pressure air into the left and right towers of the oxygen production tower 2024 in turn, so that the oxygen production tower 2024 can continuously and efficiently adsorb and produce oxygen. The produced oxygen enters the room through the oxygen port of the air nozzle, thereby improving the indoor oxygen concentration. The nitrogen is discharged from the other end of the oxygen production tower 2024 after the oxygen production tower 2024 is depressurized. The discharged nitrogen and other gases have a fast flow rate, and can effectively dissipate heat when passed into the air compressor 2034. The nitrogen gathers near the air compressor base 2033, close to the electrical box 400 inside the external unit body 100, which can have a fire prevention effect.

[0115] See attached Figure 3Due to the operation of the external fan 101 inside the external unit body 100 and the cooling fan 2032 inside the oxygen production component 200, negative pressure is formed in the compressor cavity, and the outside air enters the compressor cavity from the lower side of the right handle, enters the air compressor cavity from the air compressor base 2033 to dissipate heat for the air compressor 2034, and then passes through the heat dissipation outlet 20351 of the air compressor cover 2035, is blown out by the cooling fan 2032 and passes through the radiator 2031. At the same time, due to the operation of the external fan 101, negative pressure is formed in the external unit air duct, and the air duct inside the external unit body 100 is connected with the oxygen production component through the bottom shell heat dissipation groove 201112 on the heat dissipation bottom plate, so that the heat dissipation airflow can pass through the heat dissipation bottom plate into the air duct inside the external unit body 100 and then blow out of the external unit body 100.
