Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an ultrasonic humidifier, and in particular to a highly reliable ultrasonic humidifier that can maintain suitable environmental conditions for internal electrical components. It is related to.

[Conventional Conventional]

BACKGROUND ART Conventionally, an ultrasonic humidifier 1 as shown in the second figure has been provided as a stand-alone ultrasonic humidifier that is placed on a floor, a support plate, or the like. In the figure, 2 is a water tank, 3 is a float switch that detects the water level of water 4 in the water tank 2, 5 is a breakwater plate that prevents the water surface from undulating, and 6 is a drain that drains water overflowing from the water tank 2. Exit,
7 is an outlet for discharging the water in the aquarium 2; 8
numeral 9 is an ultrasonic transducer that atomizes the water 4 in the water tank 2; and 9 is an air intake device that is provided in the lateral direction of the water tank 2 and that sucks the air in the space to be humidified (hereinafter referred to as "humidification space"). 10 is an intake hose connected to the intake port 9 and communicates with the humidifying space; 11 is a blower; 1
2 is a motor that drives the blower 11; 13 is an intake passage provided horizontally in the lateral direction of the water tank 2;
4 is an air outlet provided at the upper part of the water tank 2; 15
16 is an electrical equipment space in which an oscillation circuit (not shown) and other electrical components are arranged.

According to the conventional ultrasonic humidifier 1 described above, the blower 1
1, the air in the humidifying space is sucked in through the intake hose 10 and the intake port 9, and the air, accompanied by minute water droplets atomized by the ultrasonic vibrator 8, is passed through the outlet 14 and the discharge hose 15. The humidifier is supplied into the humidifying space.

However, in the conventional ultrasonic humidifier 1 described above, since the intake passage 13 and the electrical equipment space 16 communicate with each other, the environmental conditions for the electrical components deteriorate, resulting in deterioration of the characteristics of the electrical components, shortening of the life span, or short circuit accidents. However, there was a drawback that the reliability of the device was reduced. In other words, since the intake passage 13 and the electrical equipment space 16 were not clearly separated, the air in the humidified space that was taken in had high humidity, so it condensed directly on the electrical components or on the blower 11, etc. Water droplets fall onto the electrical components below, leading to deterioration of the characteristics of the electrical components, shortening of their lifespan, or short-circuit accidents. In addition, when humidifying the inside of a refrigerator or thermostat, cold or hot air is taken in, so the temperature of the electrical equipment space 16 also becomes low or high, and from this point of view, electrical parts There were drawbacks that led to deterioration of characteristics and shortened lifespan.

On the other hand, in order to eliminate the above drawbacks, it is conceivable to provide a partition plate below the blower 11 to partition the intake passage 13 and the electrical equipment space 16 in the conventional ultrasonic humidifier 1 shown in the second figure.

However, in this case, there is an inconvenience that water droplets condensed on the blower 11 etc. fall and stay on the partition plate, and when cold air is taken in, condensation occurs on the lower surface of the partition plate and the water droplets are deposited on the lower surface of the partition plate. This causes defects such as deterioration of the characteristics of the electric parts, shortening of their lifespan, or short-circuit accidents.

[Problem that the invention attempts to solve]

The present invention eliminates the drawbacks of the conventional technology described above, and improves reliability by maintaining suitable environmental conditions for internal electrical components, and allows condensed water droplets to accumulate in unnecessary locations. The aim is to provide an ultrasonic humidifier that does not require

[Means for solving problems]

In order to solve the above problems, the present invention provides a stationary ultrasonic humidifier placed on the floor, support plate, etc., with an air intake passage horizontally provided in the lateral direction of the water tank, the water tank, and the water tank. The air outlet provided at the top is integrally constructed, the intake passage is provided at a higher place than the water tank, a heat insulating material is provided around them, and electrical components are arranged outside of the air insulating passage.

[Effect]

According to the present invention, the intake passage, water tank, and outlet are integrated, and the electrical components are placed outside, so the inhaled humid air does not come into contact with the electrical components, and condensation occurs on the electrical components. There is nothing to do. In addition, although dew condensation occurs inside the intake passage, since the intake passage, water tank, and outlet are integrated, and the intake passage is located at a higher place than the water tank, the water droplets that condense on the inside of the intake passage remain. It flows into the aquarium without water. Furthermore, because heat insulating material is provided around the integrated intake passage, water tank, and air outlet, the temperature of the electrical space where electrical components are installed is maintained at room temperature regardless of the temperature of the intake air. As it drips,
Even if the temperature of the intake air is low, no dew condensation will form around the intake passage or the like.

As described above, according to the present invention, the environmental conditions of the electrical components can be maintained in a suitable manner without the intake air having any effect on the electrical components, thereby improving the reliability of the device. Furthermore, water droplets condensed on the inside of the intake passage do not accumulate in unnecessary locations and cause any inconvenience.
