humidifier

Abstract

To provide a humidifier which can prevent a vaporization filter from getting wet again after a drying operation.SOLUTION: Protrusions 50b and 50a which are oriented upward and downward when a vaporization filter 9 becomes substantially parallel with a water level are formed at an external periphery of a joint 20, a recess 51a with which the protrusions 50b and 50a of the joint 20 are engaged is formed at a frame 2a of a water tank 2, and when a rotating shaft 25 is released from the joint 20, the protrusions 50b and 50a of the joint 20 are engaged with the recess 51a of the frame 2a. By this constitution, when the rotating shaft 25 is released from the joint 20, the vaporization filter 9 is prevented from being rotated, and also, the vaporization filter is prevented from getting wet with water again by withdrawing the water tank 2 after a drying operation.SELECTED DRAWING: Figure 8

Claims

1. The main body of the device, A water tank for storing water, A fan installed inside the main body of the device to blow air, The aforementioned device body includes an air intake port for taking in air from outside the main body of the device, The airflow path through which the air that has passed through the intake port flows, A vaporization filter is provided in the airflow path, the lower part of which is immersed in the water in the tank and capable of rotational drive, A turn motor that rotates the vaporization filter at a predetermined rotational speed, An outlet for blowing humidified air generated by the vaporization filter out of the main body of the appliance, A joint located at the rotation center of the vaporization filter and detachably supported by the rotation shaft of the turn motor, The system includes a control unit that controls the operation of the blower fan and the turn motor, The outer circumference of the joint is provided with a convex or concave portion that faces downward when the vaporization filter is approximately parallel to the water surface. The frame of the aquarium is provided with a recess or protrusion that engages with the protrusion or recess of the joint, A humidifier characterized in that when the rotating shaft is disengaged from the joint, the protrusion or recess of the joint engages with the recess or protrusion of the frame.

2. The humidifier according to claim 1, characterized in that the frame is provided with a guide portion that is inclined such that the recess or protrusion of the frame becomes the bottom, and the joint and the frame are guided by the guide portion when they engage.

3. The humidifier according to claim 2, characterized in that a projection is provided on the outer circumference of the joint or on the guide portion, and the projection abuts against the guide portion or the outer circumference of the joint when the joint and the frame engage.
