In the embodiment of the present invention, as shown in fig. 1 to 6, the air conditioner indoor unit includes a main unit 100, an oxygen generator 200, and a sub-unit 300. The main unit 100 includes an indoor heat exchange module 110, the main unit 100 is provided with an exhaust air duct 120 and an exhaust outlet 130 communicated with the exhaust air duct 120, and the exhaust outlet 130 is communicated with the outdoor. The oxygen generator 200 is installed in the main unit 100 to supply oxygen to the room. The handset 300 is detachably connected to the host 100, the handset 300 is provided with an air inlet 310, an air outlet 320 and a handset air duct 330 for communicating the air inlet 310 with the air outlet 320, a fan assembly 340 is arranged in the handset air duct 330, when the handset 300 is connected to the host 100, the air outlet 320 is communicated with the air exhaust duct 120, the fan assembly 340 is used for driving indoor airflow to flow into the handset air duct 330, and the indoor airflow flows through the air exhaust duct 120 through the air outlet 320 to be exhausted to the outside through the air exhaust outlet 130.

In the present embodiment, the overall shapes of the master unit 100 and the slave unit 300 may be cylindrical, elliptic cylindrical, square cylindrical, or other shapes, and the shapes of the master unit 100 and the slave unit 300 may be the same or different. The selection and design can be specifically carried out according to the actual use requirements, and the method is not limited herein. The main unit 100 extends in the vertical direction as a whole, and the main unit 100 and the sub-unit 300 may be arranged in the vertical direction so as to have a uniform cross section or a variable cross section. The heat exchange air duct 140 is disposed in the main unit 100, and the indoor heat exchange module 110 is installed in the heat exchange air duct 140 and is configured to exchange heat for air flowing through the heat exchange air duct 140 to implement cooling or heating, and the indoor heat exchange module 110 may only have a cooling function or may have both cooling and heating functions. It will be appreciated that the heat exchange air duct 140 is isolated from the exhaust air duct 120. Thus, the heat exchange air duct 140 and the exhaust air duct 120 are independent from each other and do not affect each other. The shape and configuration of the exhaust duct 120 may be designed and selected according to the shape of the main unit 100, and is not particularly limited herein. The exhaust outlet 130 may be in communication with the outside of the room through an air duct. Other specific structures of the air-conditioning indoor unit can refer to the prior art, and are not described herein again.

The sub-unit 300 is detachably mounted on the main unit 100, and the sub-unit 300 can be connected to the inside of the main unit 100, for example, the accommodating cavity 150 is provided in the main unit 100, so that the sub-unit 300 is mounted in the accommodating cavity 150, and at this time, the accommodating cavity 150 can be located at the upper part, the middle part or the lower part of the main unit 100. The sub-unit 300 may be connected to the outside of the main unit 100, such as the bottom, top, and peripheral side of the main unit 100. The connection between the sub-machine 300 and the main machine 100 may be a structural connection, for example, a connection through a snap connection, a magnetic connection, an insertion connection, or the like, or the connection between the sub-machine 300 and the main machine 100 may be a connection of a channel only, for example, the sub-machine air duct 330 of the sub-machine 300 is communicated with an air duct in the main machine 100, for example, the exhaust air duct 120 of the main machine 100. It can be understood that the sub-machine 300 can be detached from the main machine 100 by a user manually, and the control device can control the sub-machine 300 to be actively detached from the main machine 100 without manual operation of the user. When the sub-unit 300 is separated from the main unit 100, the sub-unit 300 can be moved in a circulating manner indoors and can work independently, so that the requirement of the whole indoor air treatment is met, and the air supply of the whole space is uniform. The user can move the sub-machine 300 to an indoor required position or independently move the sub-machine 300 to a certain position, such as a multi-user concentrated area, so that fixed-point air supply in a certain area can be met, long-distance, fixed-point and directional air supply is realized, and the air treatment effect is improved. Compared with the movement of the whole air conditioner indoor unit, the movement of the sub machine 300 is more flexible and convenient, so that different use requirements of users can be met. And the sub machine 300 can carry out relay air supply on the airflow blown out from the heat exchange air outlet of the main machine 100, so that the air supply distance is longer and the air supply range is wider.

The fan assembly 340 is disposed in the sub-machine air duct 330, the fan assembly 340 may specifically be a single fan or a double fan, and the fan assembly 340 may specifically include one or more of an axial flow fan, a centrifugal fan, and a cross flow fan. The fan assembly 340 is used for driving indoor airflow to flow into the sub-machine air duct 330 and flow out through the air outlet 320. The air outlet 320 and the air exhaust duct 120 may be directly communicated through a duct structure, or may be only spatially communicated, that is, the air outlet 320 supplies air towards the air exhaust duct 120. The exhaust duct 120 also has an exhaust inlet 160 such that the outlet 320 communicates with the exhaust inlet. When the handset 300 is connected to the main unit 100, the air outlet 320 communicates with the air exhaust duct 120, and the fan assembly 340 of the handset 300 can drive the airflow to be blown out from the air outlet 320, and supply the airflow to the air exhaust duct 120, and then exhaust the airflow to the outside through the air exhaust outlet 130. Therefore, the air exhaust mode of the air conditioner indoor unit can be realized. Namely, indoor dirty air can be discharged to the outdoor, so as to achieve the effect of ventilation.

The whole oxygen generator 200 may be detachably mounted on the main unit 100 or may be fixedly mounted on the main unit 100. The oxygen generator 200 can be installed outside the main unit 100, can be installed inside the main unit 100, or can be embedded in the main unit 100. It can be understood that when the oxygen generator 200 is installed in the main unit 100, the main unit 100 is provided with an oxygen outlet, and the oxygen outlet is communicated with the oxygen outlet of the oxygen generator 200, so as to output the oxygen generated by the oxygen generator 200 to the indoor space. The oxygen outlet may be provided on the front side surface of the main unit 100, or may be provided on the left and right side surfaces or the rear side surface of the main unit 100. The oxygen content can be adjusted for the area close to the air conditioner to improve the air quality. Of course, the oxygen outlet of the oxygen generator 200 can also be communicated with the heat exchange air duct 140 to be blown out from the heat exchange air outlet to the room. The oxygen generator 200 may be a molecular sieve oxygen generator, an oxygen-enriched membrane oxygen generator or other oxygen generating structures, and only needs to be capable of generating oxygen. Alternatively, the oxygen plant 200 is made to be a molecular sieve oxygen plant. That is, the oxygen plant 200 includes an air compressor and a molecular sieve assembly connected to each other. Therefore, the oxygen preparation concentration of the oxygen generator 200 is high, and the oxygen generation effect is better. The main unit 100 is provided with ventilation holes at left and right sides to ventilate and dissipate heat of the air compressor of the oxygen generator 200. When the oxygen generator 200 is opened, the indoor unit of the air conditioner is in an oxygen generation mode, so that the oxygen content of indoor air can be adjusted. The oxygen generation mode and the air exhaust mode can be independently opened or simultaneously opened, and the corresponding operation mode can be selected according to the use requirement.

The air conditioner indoor unit of the present invention enables the sub-unit 300 to be detachably mounted on the main unit 100, and enables the sub-unit 300 to be separated from the main unit 100 to independently operate. When the whole indoor quick heat exchange is ensured, the sub machine 300 can be separated from the main machine 100 to realize the whole-house movable air supply and the like, and the air supply requirement of a certain area or the whole area in a room can be flexibly adjusted through the sub machine 300, so that the flexibility of the whole air conditioner indoor machine is high, and different air supply requirements of users can be met. And the sub-machine 300 can carry out relay air supply on the heat exchange airflow blown out by the main machine 100, thereby achieving remote and multi-directional air supply. Meanwhile, the air conditioner indoor unit can supply air in multiple directions, a long distance and a whole room, and meanwhile, the sub-unit 300 is arranged on the main unit 100, so that the multi-unit storage integration is realized, the room space is saved, and the space utilization rate is improved.

In addition, set up oxygenerator 200 on host computer 100, in order to supply oxygen to indoor, and through set up the wind channel 120 of airing exhaust with outdoor intercommunication on host computer 100, utilize the submachine wind channel 330 and fan subassembly 340 of submachine 300 to realize the mode of airing exhaust of whole air conditioning indoor set, compare in adopting new trend fan and air duct system to realize drawing new trend and airing exhaust on host computer 100, need not set up new trend fan and air exhaust fan in addition on host computer 100, just can realize promoting indoor air oxygen content and discharge indoor foul wind, then very big host computer 100 space has been saved, promote space utilization, simplify the overall structure of air conditioning indoor set, reduce the material simultaneously, the manufacturing, after-sales maintenance cost, improve product reliability. And the air-conditioning indoor unit can simultaneously operate in an oxygen generation mode and an air exhaust mode and can also independently work, so that the indoor air exchange efficiency can be effectively improved.

In practice, referring to fig. 3, 4 and 7, the oxygen generator 200 has an air input pipe 210, and the air input pipe 210 is communicated with the outside.

In this embodiment, it is understood that the oxygen plant 200 has an air inlet, an oxygen outlet, and a nitrogen outlet. The oxygen generator 200 processes air introduced through the air inlet, separates exhaust gases such as oxygen and nitrogen, and outputs oxygen through the oxygen outlet and nitrogen through the nitrogen outlet. The air input line 210 has one end communicating with the air inlet and the other end communicating with the outside. So, make oxygenerator 200 to outdoor air separate oxygen to input it to indoor, in order to realize promoting the oxygen content of indoor air, and then reach the effect of fresh indoor air.

In one embodiment, as shown in fig. 3-5, the oxygen generator 200 is installed in the exhaust duct 120. It can be understood that no additional fan is arranged in the exhaust air duct 120, and the additional fan only plays a role in guiding the air in the air duct, so that the oxygen generator 200 is installed in the exhaust air duct 120, the space of the exhaust air duct 120 can be fully utilized, the additional installation space of the oxygen generator 200 is reduced, and further the main machine 100 is more compact in structure and smaller in overall size. And because the air input, the oxygen output and the nitrogen exhaust of the oxygen generator 200 are all output through respective independent pipelines, the installation of the oxygen generator 200 in the exhaust air duct 120 does not affect the proceeding of the exhaust mode, i.e. the oxygen generator mode and the exhaust mode can be independently opened or simultaneously opened. In other embodiments, the oxygen generator 200 can also be installed at a position outside the exhaust duct 120 of the main machine 100.

Further, referring to fig. 3, 4 and 7, the oxygen generator 200 further includes a nitrogen exhaust line 220, and the nitrogen exhaust line 220 and the air input line 210 are communicated with the outdoor through the exhaust outlet 130. It can be understood that the waste gas such as nitrogen gas generated by the oxygen generator 200 is required to be discharged to the outside. When the oxygen generator 200 is installed in the exhaust air duct 120, the nitrogen gas exhaust pipeline 220 and the air input pipeline 210 are communicated with the outside through the exhaust outlet 130, so that the nitrogen gas exhaust pipeline 220 and the air input pipeline 210 do not need to be additionally arranged on the main machine 100 to extend out of the room, the number of holes formed in the main machine 100 and the number of holes formed in the wall surface can be further avoided, and the structure and the installation process are simplified. Specifically, the nitrogen gas exhaust line 220 and the air input line 210 are respectively disposed at two opposite sides of the exhaust outlet 130, so that the distance between the nitrogen gas exhaust line 220 and the air input line 210 can be increased, thereby avoiding air flow interference and improving oxygen generation efficiency.

In an embodiment, as shown in fig. 3 to 5 and 7, the oxygen generator 200 further includes an oxygen output pipeline 230, the main unit 100 further includes a heat exchange air duct 140, the indoor heat exchange module 110 is disposed in the heat exchange air duct 140, and the oxygen output pipeline 230 is communicated with the heat exchange air duct 140; and/or, the main body 100 is provided with an oxygen outlet, and the oxygen output pipeline 230 is communicated with the indoor space through the oxygen outlet.

In this embodiment, it can be understood that the main unit 100 further includes a heat exchanging air inlet and a heat exchanging air outlet, which are communicated with the heat exchanging air duct 140. The indoor heat exchange module 110 includes a heat exchanger and a heat exchange fan, the heat exchange fan drives an airflow to enter the heat exchange air duct 140 from the heat exchange air inlet, and the airflow is blown out from the heat exchange air outlet after being subjected to heat exchange by the heat exchanger, so as to realize indoor refrigeration or heating. Through making oxygen output pipeline 230 and heat transfer wind channel 140 intercommunication, usable heat transfer fan and heat transfer export then for the high concentration oxygen of taking out by oxygenerator 200 system can be along with the heat transfer air current diffusion to the interior space of heat transfer air outlet, and then can the oxygen concentration of the whole interior space of uniform adjustment. When the oxygen outlet is formed in the main unit 100, the oxygen output pipeline 230 is communicated with the indoor through the oxygen outlet, the oxygen produced by the oxygen producing device 200 can be directly blown to the indoor, the oxygen content of the area close to the main unit 100 is adjusted, and the air quality is improved. When the oxygen output pipeline 230 is communicated with the heat exchange air duct 140 and the oxygen output pipeline 230 is communicated with the indoor space through the oxygen outlet, the oxygen output pipeline 230 can output oxygen simultaneously through the three-way connecting pipe, and one pipeline is communicated with the heat exchange air duct 140, and the other pipeline is communicated with the indoor space through the oxygen outlet. So, the oxygen that makes oxygenerator 200 can carry out oxygen content through the heat transfer air outlet to the region of keeping away from host computer 100 and adjust, and can carry out oxygen content through the oxygen export to the region of being close to host computer 100 simultaneously and adjust, and then make indoor each regional homoenergetic effectively adjust oxygen content, promote indoor even oxygenation effect.

In one embodiment, as shown in fig. 1 to 5, the main unit 100 extends in an up-and-down direction, the main unit 100 further includes an accommodating chamber 150, and the sub-unit 300 is detachably mounted in the accommodating chamber 150.

Generally, the shape of the receiving cavity 150 is adapted to the shape of the sub-machine 300, i.e. in the non-operating state, the sub-machine 300 is entirely received in the receiving cavity 150. Of course, part of the sub-machine 300 may be located in the accommodating cavity 150, and part of the sub-machine may be located outside the accommodating cavity 150, that is, part of the sub-machine may be exposed to the main machine 100. The receiving chamber 150 may be formed by partially hollowing out the main body 100. The receiving cavity 150 may also be formed by enclosing a supporting arm on the main unit 100, and the exhaust duct 120 is located above the sub-unit 300. Through at least partly setting up the submachine 300 in the chamber 150 that holds of host computer 100, compare in the whole with the host computer 100 concatenation of submachine 300, it is whole uniformity after both connect to keep more easily to promote user's use experience.

The sub-machine 300 is detachably installed in the accommodating chamber 150, so that the sub-machine 300 can be directly placed in the accommodating chamber 150 and separated from the accommodating chamber 150 by rolling, sliding and the like. The sub-machine 300 can also be installed in the accommodating cavity 150 in a limiting manner through a limiting structure, for example, connected in the accommodating cavity 150 through a snap connection, a magnetic connection, and the like. The sub-unit 300 can be installed in the receiving cavity 150 and removed from the receiving cavity 150 in various ways, which are not listed here. The user can manually move the sub-unit 300 out of the accommodating cavity 150, so that the sub-unit 300 is separated from the main unit 100. The sub-machine 300 can also be controlled to move out of the main machine 100, at this time, the accommodating cavity 150 needs to be arranged at the bottom of the main machine 100, so that the sub-machine 300 can move out of the accommodating cavity 150.
