DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a humidifier such as an ultrasonic humidifier provided with a blower for blowing air into a water tank.

(B) Prior art In this type of humidifier, a sirocco fan blower is provided in the equipment room in order to increase the static pressure and air volume of the blower.
It is known from Japanese Utility Model Publication No. 61-33456. By the way, in this conventional structure, because the size of the blower is inevitably large in the height direction, the equipment room is made horizontally long and the blower, transformer, ultrasonic oscillator, etc. are placed in the longitudinal direction of the equipment room. They had to be installed alongside each other, and there was a drawback that the installation space for the humidifier body was increased accordingly.

It is also possible to use a thin propeller fan instead of the sirocco fan and place the propeller fan blower directly under the ultrasonic oscillator to narrow the width of the equipment room to reduce the installation space of the humidifier body. However, since the propeller fan has a low static pressure, the amount of air that flows out from the air outlet with a narrowed opening area is small, the fan tends to run dry, and the air leaks from the inlet side.

Also, since the entire humidifier becomes high, the installation condition of the humidifier becomes unstable, and it is easy for the humidifier to fall over due to slight vibrations, and when the humidifier is installed in the recess in the room, there is a concern that the upper surface may get wet. .

(C) Problems to be Solved by the Invention The present invention has been made in view of the above-mentioned facts,
A humidifier with a small installation space and a small height is provided, and a propeller fan blower can be used efficiently, and furthermore, electric parts inside the humidifier body can be cooled efficiently. To aim.

(D) Means for Solving the Problems In the present invention, the upper surface has a water tank recessed downward, the center of the bottom surface has an air inlet, and the equipment chamber is formed between the water tank and the bottom surface. , A cylindrical humidifier body with an ultrasonic transducer placed in the water in the water tank, and a lower part with a water supply port is inserted into the water tank of the humidifier body, and the upper part placed on the humidifier body is the humidifier body. A water supply tank having a substantially flush cylindrical shape, a cylindrical mist derivation member that is interposed between the humidifier body and the water supply tank and discharges the mist of the water tank portion sideways, and an equipment chamber of the humidifier body. An air passage for communicating with the water tank is provided, and in the equipment room of the humidifier main body, a propeller fan having an outer dimension that is larger than the suction opening and slightly smaller than the inner diameter of the humidifier main body is provided facing the suction opening. Just above the propeller fan in the chamber This is a configuration in which a plurality of electric components are provided side by side.

(E) Action With this configuration, the entire humidifier has a cylindrical shape whose diameter is determined by the outer dimensions of the propeller fan, and the entire internal space of the humidifier body can be used as a wind tunnel for the propeller fan, and the air from the propeller fan can be blown. Since it can be smoothly guided to the water tank through the passage and part of the wind can be prevented from leaking from the suction port, the propeller fan's capacity is fully exerted, and the propeller fan can be made as small as possible and compact installation. It will be possible. In addition, the lower part of the water supply tank is inserted into the water tank formed by denting the upper surface of the humidifier body downward, and in the equipment room of the humidifier body, a plurality of electric parts for driving the ultrasonic transducer are installed in the propeller fan. Since they are installed side by side directly above, not only it is possible to keep the height of the humidifier as low as possible while enabling compact installation, but also multiple electric parts are efficiently cooled and ultrasonic humidification is possible. This is done efficiently by utilizing the heat generated by the electric parts.

Furthermore, since the cylindrical mist derivation member is interposed between the humidifier main body and the water supply tank and the mist in the water tank portion is discharged sideways from this mist derivation member, the height of the humidifier is further improved. In addition to being suppressed, even if the humidifier is installed in a recess in the room, it does not wet the upper surface and water droplets do not adhere to the lower surface of the water tank, so water droplets will not be generated when carrying the water tank for water supply. No need to worry about dropping or getting your hands wet.
