DETAILED DESCRIPTION

[0038] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0039] The terms "a", "an", "the", "" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.

[0040] See also Figures 1 to 4 An embodiment of the present invention provides an indoor air treatment machine, including: a box assembly 7, a filter assembly 6, a water supply assembly and a fan 714 assembly. The box assembly 7 has a chamber, and the box assembly 7 has at least one air inlet chamber 727 and an air outlet chamber 741 connected to the chamber; the filter assembly 6 is arranged in the air inlet chamber 727, and is used to purify and humidify the air entering the chamber from the air inlet chamber 727. The filter assembly 6 includes a humidifying wet membrane filter unit 63 and an IFD module processing unit. Along the air flow direction, the IFD module processing unit is located on the upstream side relative to the humidifying wet membrane filter unit 63. The IFD module processing unit purifies the air, and the humidifying wet membrane filter unit 63 further evolves and humidifies the air purified by the IFD module processing unit. The water supply component is arranged in the box component 7, and the water supply component is used to supply water to the humidifying membrane filter unit 63 to form a water film on the surface of the humidifying membrane filter unit 63. The water film can purify the air flowing through, and the evaporation of the water film can humidify the air; the fan 714 component is arranged in the air outlet cavity 741, and is used to drive the air flow.

[0041] In the embodiment of the present invention, after the fan 714 component arranged in the air outlet chamber 741 is started, a negative pressure can be formed in the box assembly 7, so that air enters the box assembly 7 from the air inlet chamber 727 and flows out of the box assembly 7 from the air outlet chamber 741. The water supply component is used to supply water to the humidifying membrane filter unit 63 to form a water film on the surface of the humidifying membrane filter unit 63. When the air passes through the IFD module processing unit, it is processed by a micro-electrostatic electric field, and the particles and bacteria, viruses, and microorganisms attached to the particles are adsorbed, ionized, and carbonized. The cell walls of bacteria, viruses, and microorganisms are punctured and penetrate into the cells, destroying the internal mechanisms of the cells and causing death, thereby achieving the effect of purifying, sterilizing, and disinfecting the air. When passing through the humidifying membrane filter unit, the water film formed on the surface of the humidifying membrane filter unit 63 evaporates and absorbs heat, thereby achieving the purpose of humidifying the air, washing the air, and purifying the air. Due to the use of the humidifying wet membrane filter unit 63 and the IFD module processing unit, there is no need to replace the filter element. It not only realizes the upgrade of the product in terms of meeting the comprehensive control of indoor air pollution and effectively improving the comprehensive air quality, but also reduces the cost of consumables used in the later stage, alleviates the economic pressure of users in subsequent use, and actively responds to the national policy requirements of energy conservation, environmental protection and low carbon.

The fresh air filter compartment 738 is provided with a fresh air interface 737 and a fresh air filter 739. The fresh air interface 737 is used for connecting the fresh air duct when there is a need to use external fresh air, and the fresh air filter 739 is used to purify the external air introduced into the fresh air duct.

[0064] An air guide ring 716 may also be provided in the air outlet cavity 741 to facilitate the discharge of air from the air outlet cavity 741 .

[0065] An air uniforming plate 719 may be provided in the air inlet cavity 727 to distribute the air.

[0066] The following is a detailed description of the overall working principle and use of the indoor air treatment machine:

[0067] When the indoor air treatment machine provided by the embodiment of the present invention is working, it is necessary to first connect to the external water supply source through the water inlet pipe interface 732, connect the power through the power socket 712 and turn on the power switch 711, touch the touch button of the front panel component 4 to turn on the machine, and the water inlet solenoid valve 731 opens the water supply tank 21 to replenish water. The humidification water pump 28 arranged in the water tank 21 lifts the water in the water tank 21 to the water distributor through the upper water pipe 729, and sprays it on the top of the humidification wet membrane filter unit 63 through the water distributor. Under the action of gravity, the water naturally flows down from the top of the humidification wet membrane filter unit 63 to form a water film. The flowing water gathers in the water receiving tray 728 and then flows back to the water tank 21 through the return water port 720. This state is maintained during operation. The fan 714 disposed at the top of the box assembly 7 is working, and the external air is sucked into the air inlet chamber 727 by the strong negative pressure generated by the fan 714. After passing through the left and right air inlet grille door assemblies 5, the external air passes through the IFD electric field module filter 61, the IFD dust collection module filter 62 and the humidification membrane filter unit 63 in sequence, and the first treatment stage of the inhaled air is completed. The air after the first treatment stage is gathered in the air outlet chamber 741, and is irradiated by the ozone-free ultraviolet lamp 722 in the air outlet chamber 741. The high concentration of negative oxygen ions released by the negative oxygen ion generator 723 purifies and refreshes the inhaled air, and the second treatment stage of the inhaled air is completed. The air that has completed the first and second stage treatments is sent out through the top hole-shaped mesh structure air outlet grille 31, and finally achieves the effects of air purification and dust removal, air disinfection and sterilization, air humidification, and fresh air, realizing all-round management of indoor air.

[0068] The indoor air treatment machine provided by the present invention is compatible with two water supply modes: automatic water addition and manual water addition.

[0069] Working principle of automatic water adding: When the indoor air treatment machine provided by the present invention is used in a fixed position or the conditions for connecting a water pipe are available at the use site, the external water supply source can be connected through the water inlet pipe interface 732 to enable automatic water adding; when the liquid level sensor group 26 detects that there is no water in the water tank 21, it feeds back a corresponding electrical signal to the control display screen 44, the water inlet solenoid valve 731 opens, and water is added to the water tank 21 through the water inlet float 29. When the water level in the water tank 21 rises to a predetermined height, the liquid level sensor group 26 detects the change in the water level height and feeds back a corresponding electrical signal to the control display screen 44, and the water inlet solenoid valve 731 is closed; when working, the liquid level sensor group 26 detects the change in the water level in the water tank 21 in real time and feeds back a corresponding electrical signal to the control display screen 44 to ensure that the water level in the water tank 21 is always maintained within a predetermined water level height range.

[0070] Working principle of manual water adding: When the indoor air treatment machine provided by the present invention is used in a mobile manner or when there is no water pipe connection available at the use site, after opening the right air inlet grille door assembly 5, the water tank 21 can be pulled horizontally outward through the water tank handle 22. After the water tank 21 is pulled out, water is manually added to the water tank 21 using a container until the manual water adding water level reaches the liquid level indicator 25. After completing the water adding operation, push the water tank 21 horizontally inward to reset it, and close the right air inlet grille door assembly 5. During operation, the liquid level sensor group 26 detects the water level changes in the water tank 21 in real time and feeds back the corresponding electrical signal to the control display screen 44. When there is a lack of water in the water tank 21, the control display screen 44 will give a corresponding sound and light prompt signal. At this time, it is necessary to repeat the above-mentioned manual water adding operation to add water to the water tank 21 again.

[0071] Two control operation modes: The indoor air treatment machine provided by the present invention is compatible with two control operation modes. One is to set the corresponding function by touching the touch button below the light-transmitting display window on the tempered glass decorative panel 43; it is also compatible with mobile phone WIFI remote intelligent control and supports mobile phone APP intelligent remote control; both control modes can steplessly adjust the speed of the fan 714; the speed of the fan 714 can be steplessly adjusted by turning the air volume adjustment knob 33 clockwise or counterclockwise to achieve the purpose of changing the air volume and adjusting the sound volume.
