A micromist sauna device comprises: a circulating air supply device (11) for circulating indoor air, a heating device (12) for heating air, and a humidifier (20) arranged at the downstream side of the heating device (12) and used for humidifying air. The lower part of the humidifier (20) is provided with a water storage portion (21) for storing water, and the upper part is provided with a humidification portion (22) for sucking up the water in the water storage portion (21) and spraying mist; and a crusher (60) is fixedly arranged around the humidification portion (22), the crusher (60) has multiple ribs (61) and is cone-shaped, and an opening (62) of an airflow channel is formed between the multiple ribs (61). The advantage of the device is that the efficiency of contact between air and water droplets is high, so that the humidification loss and the heat loss are reduced.
A: A humidification device and humidification method used for a core-manufacturing machine, which are used for preserving the moisture of or humidifying one or more areas in a core sand mixing device, conveying device, storage device and sand ejecting device of the core-manufacturing machine; the invention comprises a humidification device, a control device and a humidification pipe (4) that communicates with the humidification device and an area to undergo moisture preservation or humidification, and is characterized in that: the humidification device is mainly composed of a water tank (2), a water intake valve (10) and atomization devices equal in number to the areas to undergo moisture preservation or humidification; each atomization device is provided with a vertically disposed cage mist chamber (3), a bottom portion of the cage mist chamber (3) being provided with a nozzle (5) having an upward outlet, and a top portion of the cage mist chamber (3) communicating with the humidification pipe (4); the nozzle (5) is connected to a water suction pipe (6) and an air intake pipe (7), a water intake port of the suction pipe (6) is located within the water tank (2), and the air inlet pipe (7) is connected to a compressed air source by means of an air valve (8); the size of the cage mist chamber (3) matches the minimum dispersion area sprayed by the nozzle (5). The invention facilitates control and may guarantee the transportation of mist, and outputted water mist particles have uniform dispersibility and stable flow rate, while humidity is easy to control; moreover, the structure is simple and reliable, and is suitable for harsh working environments.
B: A micro-mist sauna apparatus (10), in which an air outlet (12) of a humidification unit (15) and an air-directing plate (19) on a panel (18) are connected therebetween via an air duct conversion structure (20). The upper part of the air duct conversion structure (20) forms a first opening (21) that is consistent in size with the air outlet (12) of the humidification unit (15). A first group of paired sides (22) of the first opening (21) extend obliquely inwards and downwards for a certain length to form a first oblique part (23). The middle parts of a second group of paired sides (24) of the first opening (21) extend obliquely outwards and downwards for a certain length to form a second oblique part (25). The lower end of the first oblique part (23) and the lower end of the second oblique part (25) encircle to form a second opening (26). This structure allows the micro-mist sauna apparatus to blow an even flow of air.
C: An air conditioner humidification system, comprising a water storage device (1) and a water conveying device (2) that are integrated into an outdoor unit, as well as a humidification device (3) that is integrated into an indoor unit. The water storage device (1) comprises a water molecule-permeable membrane (11) and a first water storage part (12), wherein water molecules in the air may enter the first water storage part (12) by means of the water molecule-permeable membrane (11). The water conveying device (2) is used for conveying water in the water storage device (1) to the humidification device (3). The humidification device (3) is used for vaporizing water which is sent by the water conveying device (2) into water vapor, wherein the water vapor may enter into a room to humidify the air in the room. Water does not need to be added in the system, and the water molecule-permeable membrane has the function of selectively permeating water molecules instead of nitrogen, oxygen and other substances, thus achieving the effect of purifying water molecules, reducing the generation of water scale, and solving the problem in which existing air conditioners do not have a humidification function or in which air conditioners which do have a humidification function have a low degree of automation.
D: An air handling unit for an air conditioner and a control method therefor, and an air conditioner. The air handling unit (1) comprises a housing (10); the housing (10) is provided with an air inlet and an air outlet (13); an air duct is formed inside the housing (10); a fan (21), a water storage tank (31), a water tank heating apparatus (33), and a washing apparatus (40) are provided inside the air duct. The control method comprises: determining, when the air handling unit (1) is in a washing mode, whether a preset heating starting condition is satisfied, wherein in the washing mode, the washing apparatus (40) is in an operating state; and if the heating starting condition is satisfied, starting the water tank heating apparatus (33) to heat the water inside the water storage tank (31) so as to raise the temperature of the water, thus transferring, when the water is in contact with an air flow, at least part of heat from the water to the air flow, thereby raising the temperature of the air flow. By means of the air conditioner, the heating of the air flow is converted into the heating of the water, so that the purification, humidification and temperature rise of the air flow are performed at the same time, and thus the air can be effectively humidified and purified by washing, the temperature of the air can be compensated, and the air conditioner can be assisted in heating.
