In addition, the meaning of "and/or" appearing throughout is to include three juxtapositions, exemplified by "A and/or B" including either scheme A, or scheme B, or a scheme in which both A and B are satisfied.

The invention provides a floor type air conditioner indoor unit.

In the embodiment of the present invention, as shown in fig. 1 to 7, the floor type air conditioner indoor unit includes a main unit 100, a sub-unit 200, an oxygen generation module 300, and an ion generator 400, and the main unit 100 includes an indoor heat exchange module. The sub-unit 200 is detachably connected to the main unit 100, and the sub-unit 200 can operate independently when the sub-unit 200 is detached from the main unit 100. The oxygen generation module 300 is used to generate oxygen; the ionizer 400 is used to generate negative ions. Wherein the oxygen generation module 300 and/or the ionizer 400 are mounted on the sub-machine 200.

In the present embodiment, the overall shapes of the master unit 100 and the slave unit 200 may be cylindrical, elliptic cylindrical, square cylindrical, or other shapes, and the shapes of the master unit 100 and the slave unit 200 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. Optionally, the cross section of the housing is rectangular. So for the whole square column shape setting that is of submachine 200, then the arrangement of the inside air treatment module isotructure of submachine 200 is compacter, and then reduces the volume and the occupation space of submachine 200. The main unit 100 and the sub unit 200 extend in the vertical direction as a whole, and the main unit 100 and the sub unit 200 may be arranged in the vertical direction with a uniform cross section or a variable cross section. The indoor heat exchange module is provided with a heat exchange air duct, and an air treatment air duct 223 is formed in the submachine 200. When the slave unit 200 is connected to the master unit 100, the heat exchange duct and the air treatment duct 223 may be isolated from each other or may be connected to each other. In practice, when the sub-unit 200 is connected to the main unit 100, the heat exchange duct and the air treatment duct 223 are isolated from each other. Thus, the heat exchange air duct and the air treatment air duct 223 are independent from each other and do not affect each other, so that the heat exchange effect of the indoor heat exchange module is not affected when the sub-machine 200 is connected with and separated from the main machine 100, and the heat exchange stability of the whole floor type air conditioner indoor machine is ensured.

The indoor heat exchange module is used for exchanging heat for the air flow passing through the heat exchange air duct so as to realize refrigeration or heating. The indoor heat exchange module can only have a refrigerating function and can also have a refrigerating function and a heating function. It can be understood that the main unit 100 further includes a heat exchange air inlet and a heat exchange air outlet communicated with the heat exchange air duct. The heat exchange assembly is arranged in the heat exchange air duct and comprises a heat exchanger and a heat exchange fan, the heat exchange fan drives airflow to enter the heat exchange air duct from the heat exchange air inlet and blow out from the heat exchange air outlet after heat exchange of the heat exchanger, and therefore indoor refrigeration or heating is achieved.

The sub-unit 200 can also be connected to the outside of the main unit 100, such as the bottom, top, peripheral side, etc. of the main unit 100. The connection between the sub-unit 200 and the main unit 100 can be a structural connection, such as a snap connection, a magnetic connection, or an insertion connection. It can be understood that the sub-machine 200 can be detached from the main machine 100 by the user's manual detachment, and the control device can control the sub-machine 200 to be actively detached from the main machine 100 without the user's manual operation. When the sub-machine 200 is detached from the main machine 100, the sub-machine 200 can operate independently, that is, the sub-machine 200 has an independent power supply, and power can be supplied to the sub-machine 200 by using a storage battery or a direct-plug power supply, so as to realize the independent operation of the sub-machine 200. When the sub-unit 200 is mounted to the main unit 100, the sub-unit 200 is powered by the main unit 100, and the circuit between the main unit 100 and the sub-unit 200 can be conducted by a power connection electrode plate, a charging module, or the like.

When the sub-unit 200 is separated from the main unit 100, the sub-unit 200 can move in a circulating manner in the room to meet the requirement of the whole indoor air treatment and ensure that the air supply of the whole space is uniform. The user can move the sub-machine 200 to an indoor required position or independently move the sub-machine 200 to a certain position, such as a multi-user concentrated area, through manual movement, 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 method for moving the whole floor type air conditioner indoor unit, the sub-unit 200 can be moved more flexibly and conveniently, so that different use requirements of users can be met. And the sub-machine 200 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.

Oxygen generation module 300 can produce oxygen by hydrolysis, such that oxygen generation module 300 is an electrolytic water oxygen generator. Oxygen generation module 300 can also produce oxygen by separating air, such as making oxygen generation module 300 an air separation oxygen generator. Of course, oxygen generation module 300 can also generate oxygen in other ways, and is not limited in this regard. The ionizer 400 may be specifically an anion generator 400, and the anion generator 400 includes a needle-tip electrode through which high-voltage ionized air is output to generate anions. The ion generator 400 may be of various types, and only needs to be capable of generating enough negative ions, and is not particularly limited herein. Oxygen is generated through the oxygen generation module 300, and the ion generator 400 generates negative ions, so that the negative ions are combined with the oxygen to form negative oxygen ions, and the negative oxygen ions are beneficial to physical and psychological health of a human body.

Only the oxygen generation module 300 or the ionizer 400 may be mounted on the sub-machine 200, or the oxygen generation module 300 and the ionizer 400 may be mounted on the sub-machine 200 at the same time. Specifically, the ion generator 400 is an anion module, the submachine 200 is provided with an anion module, and the main machine 100 is provided with an oxygen generation module 300. In some embodiments, oxygen generation module 300 can also be placed on an outdoor unit such that only oxygen outlet 320 of oxygen generation module 300 is in communication with the room. Thus, the generating area of the negative oxygen ions can be changed by moving the sub-unit 200, so that the generating area of the negative oxygen ions in the space can be adjusted. The user can move the sub-machine 200 manually or remotely, and the sub-machine 200 can be detected autonomously and moved to a required position. Therefore, when the user walks and changes the position, the submachine 200 can be moved to the position of the user, negative oxygen ions can be released in the area of the user, the concentration of the negative oxygen ions at the position of the user is improved, the air freshness of the position of the user is improved, and the effect of improving the breathing environment of the user to the maximum extent is achieved.

Specifically, the oxygen generation concentration and the oxygen generation flow of the oxygen generation module 300 can be adjusted by controlling the oxygen generation module 300 to supply air to the area where the human body is located. The anion generator 400 can be controlled to send anions to the region where the human body is located, the anion generating concentration and the anion generating efficiency are improved, the anion concentration of the region where the human body is located is adjusted, and the negative oxygen ion concentration of the region where the human body is located is adjusted. Of course, on the premise that the sub-machine 200 can move autonomously, the sub-machine 200 can be controlled to move to the area where the human body is located, so that the concentration of the negative oxygen ions in the area where the human body is located is increased. Make ion generator 400 and/or system oxygen module 300 adjust the regional negative oxygen ion concentration in human body according to human activity information, then can realize real-time detection human activity information to guarantee that the regional negative oxygen ion concentration in human body can reach the requirement always, realize intelligent control, promote user's use and experience.
