Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a humidifying device for a refrigerated case for humidifying the inside of a refrigerated case in which fresh foods such as vegetables and fruits are stored and displayed for a long period of time.

(b) Conventional technology As disclosed in Japanese Patent Application Laid-open No. 60-29579, this kind of conventional humidifier for a refrigerated case is designed to adjust the width of the refrigerated case in order to discharge the maximum amount of mist when the power is turned on. If the size is short, it will humidify too much. Therefore, vegetables etc. are easily damaged by excessive humidification and have the disadvantage that they cannot maintain their freshness. Another disadvantage is that when the amount of humidification is large, the mist makes it difficult to see vegetables, etc., and the display case, which serves as a display, cannot fulfill its role.

However, if the width of the refrigerating case is long, the amount of humidification may be constant, so it is not necessarily necessary to adjust the amount of humidification.

(c) Problems to be solved by the invention In view of the problems of the prior art mentioned above, the present invention solves the following problems:
To provide a system that can be applied to both models that require humidification amount adjustment and models that do not, and that allows the humidification amount to be adjusted while checking the humidification state inside a refrigerated case.

(d) Means for Solving the Problems This invention includes a humidifier main body that is placed on the top surface of a refrigerated case having an opening on the front surface and supplies mist into the refrigerated case through an outlet pipe; A changeover switch is provided on the main body of the humidifier to change the amount of humidification in the humidification device between constant and variable, and a changeover switch is provided near the front opening of the refrigerated case to change the amount of humidification to a variable state. The humidifying device is provided with a humidifying amount adjusting device that adjusts the humidifying amount in the humidifying device main body at a certain time, and the humidifying device main body and the humidifying amount adjusting device are detachably connected via a lead wire and a connector.

(e) Effect With this configuration, the humidifier can be applied to both refrigerated cases that require adjustment of the humidification amount and refrigerated cases that do not require the humidification amount adjustment by changing the changeover switch. In some cases, the humidification amount adjustment device is installed near the front opening of the refrigerated case, so adjust the amount of humidification while checking the humidification status inside the refrigerated case to prevent the amount of humidification from becoming excessive or insufficient. The amount of humidification can be adjusted accurately according to the width of the refrigerated case and the products displayed in the refrigerated case. Furthermore, since the humidifier body and the humidification amount adjustment device are detachably connected via lead wires and connectors, the humidification amount adjustment device can be removed if humidification amount adjustment is not required.
