Description

Liquid micronizing device and humidifying device Technical Field The present invention relates to a liquid refining apparatus and a humidifying apparatus. Background In recent years, high airtight houses have been increasing, and the relative humidity in the room tends to decrease during the heating operation of the air conditioner. In order to cope with the drying accompanied by the decrease in relative humidity, the demand for the humidifying device is increasing. As an example of the humidifying device, there is known a centrifugal crushing type humidifying device that pulverizes water in a water reservoir by centrifugation, and humidifies the water by imparting air thereto (for example, patent document 1). Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 2022-115918 Disclosure of Invention In this way, in the liquid micronizing device that constitutes the humidifying device and performs centrifugal disruption, water such as water droplets adhering to the inner surface of the water storage portion is dried, and scale components such as calcium components and magnesium components contained in the water are precipitated. The precipitated scale component is drawn into the water pipe together with water, but is not discharged to the outside of the water pipe, and adheres to the inner surface of the water pipe, thereby preventing the discharge of water from the water pipe, and there is a concern that the humidifying ability may be lowered. The invention provides a liquid micronizing device capable of maintaining humidifying capability even in long-time use and a humidifying device provided with the liquid micronizing device. The liquid micronizing device comprises a water storage part for storing water, a water pumping pipe having a pumping opening arranged below and pumping water from the water storage part through the pumping opening by rotation and discharging the water along a centrifugal direction, a groove part arranged on the inner surface of the water storage part, and a water outlet arranged on the groove part and opening towards the travelling direction of the rotary water flow generated by rotation of the pumping pipe and communicating the inside and the outside of the water storage part. The humidifying device of the present invention is provided with the liquid micronizing device. According to the present invention, it is possible to provide a liquid refining apparatus capable of maintaining a humidifying ability even in long-term use, and a humidifying apparatus provided with the liquid refining apparatus.
