Description

Detailed Description of the Invention (a) Industrial Application Field The present invention relates to an ultrasonic humidifier, and more specifically, it is used in a refrigerated showcase for storing and displaying fresh foods such as vegetables and fruits for a long period of time. The present invention relates to a sterilizer for a humidifier whose typical purpose is to humidify food products to maintain their freshness.

(b) Prior Art A humidifying device used for a refrigerated showcase will be explained below as an example.

Conventionally, this kind of humidifying device, as disclosed in Japanese Patent Application Laid-Open No. 60-29579, has a humidifying device body placed on the top surface of a refrigerated showcase, and an ultrasonic vibrator attached to a water tank generates fog. This mist is then guided into the showcase through a duct to humidify it.

However, with this conventional device, the main body is placed on the top surface of the showcase, which is a relatively high temperature part of the room, and due to long-term use, the humidifying water in the atomizing water tank and the inside of the duct adhere to the main body. Water droplets and bacteria were likely to breed or breed easily.

This phenomenon is particularly likely to occur during the summer, when temperatures are high throughout the year, and it is necessary to regularly clean the inside of the atomizing water tank or duct to prevent spoilage and the growth of bacteria, which is a very troublesome task. Ta. In addition, in areas where the water quality is not very good, water may be introduced into the atomizing tank through a water purifier, and depending on the type of water purifier, the chlorine contained in tap water may be removed, reducing the bactericidal effect. There were cases where the proliferation of various bacteria in the atomization tank became significant.

(c) Problems to be Solved by the Invention In the above-mentioned conventional technology, due to the fact that it is installed in a place high above the floor, which is relatively hot even indoors, and due to long-term use,
The humidifying water in the atomizing aquarium can breed bacteria and cause spoilage, and if you humidify the inside of the showcase with such humidifying water, unhygienic mist may cause food to be stored or displayed. This has caused problems in that food products become very unhygienic and become perishable.

Therefore, the present invention provides a humidifier that constantly supplies sanitary mist and also sterilizes and extinguishes the atomizing water tank and the mist transport path.

(d) Means for Solving the Problems The present invention solves the above-mentioned problems, and will be explained below based on examples.

Ultrasonic transducer (

Note that this bagged sterilizer is not limited to being placed in the cylinder (33), but is used to store outside air taken in by the blower (30) until it is conveyed to the atomization water tank (18). It can be placed anywhere as long as it is on the distribution route. Furthermore, the disinfectant is not limited to sodium hypochlorite (43), and any disinfectant that produces a disinfecting and disinfecting effect when dissolved in water, such as oar powder, may be used. Furthermore, if the sterilization/disinfectant effect of the disinfectant decreases and the efficacy can no longer be expected, the entire container (37) can be replaced, and if it is equipped with a display device that displays the degree of decrease in its efficacy, it will be a guideline for when to replace it. is clearer and more hygienic.

The configuration of the present invention is as described above, and its operation will be explained below. When the power switch is turned on, the blower <30)
and the ultrasonic oscillator (23) starts, and the ultrasonic transducer (2
1) is driven, and a water column (C) is generated on the water surface of the water tank 18). Fog is generated around this water column (C), and the blower (
30), the air flows into the water tank <18), passes through the outlet pipe (25) and the communication pipe (27), joins the cold air flow in the refrigerated showcase (1), and humidifies the storage room (A). .

On the other hand, by starting the blower (30), the outside air is taken in from the air intake port (34) after the dust has been collected, and when a part of the outside air passes through the container (37), sodium hypochlorite (43) Carry away the powder together with the case body (
15) Transport inside. This transported sodium hypochlorite (43) falls on the water in the water tank (18) and water droplets that are further transported and adhere to the inner surface of the outlet pipe (25) and communication pipe (27) as ducts. , dissolves in water and ionizes Cj20
- produces an anion. This C! 0- is an aquarium (18
) and water droplets adhering to the inner surface of the transport duct, as well as the mist. For this reason, a refrigerated showcase (1
) The mist conveyed in the water tank (18) is always hygienic and
It is possible to prevent the occurrence and proliferation of various bacteria inside the interior and ducts. Moreover, in the container (37), the slide plate (4
By adjusting the position of 2), the discharge holes (36) (36)... provided in the container (37) and the communication holes (41) (41)... provided in the slide plate (42) can be adjusted. Since the degree of the gap formed changes, the amount of powdered disinfectant that is transported can be adjusted.

(G) Effects of the invention The present invention is as described above, and by disposing a powdered sterilizer in the circulation path of the outside air taken in by the blower,
The powdered sterilizer can be conveyed into the atomizing tank and the duct 1 to 1 along with the outside air, and the water in the tank and water droplets adhering to the inner surface of the duct can be sterilized and disinfected. Also,
Since the powdered disinfectant is transported by the air from the blower, it can be expected to have a sterilizing effect even against the generated fog, and it is also possible to transport the disinfectant to every corner of the water droplets that exist in the ventilation path. Can perform sterilization over a wide range.
