Description

DETAILED DESCRIPTION OF THE INVENTION [Technical field to which the invention pertains] The present invention relates to a refrigerated open air cooler case with a humidifier that allows products to be humidified without receiving water supply from the outside.

[Prior art and its problems]

To keep the products fresh, humidifiers are installed on the shelves where the products are displayed, and moisture is added to the products at the Open Showcase. There are things that are designed to provide.

By the way, in order to supply water to the humidifier, conventional refrigerated open showcases with humidifiers had to be connected to water pipes outside the machine using piping, making the installation work extremely complicated.

[Purpose of the invention]

An object of the present invention is to provide a refrigerated open showcase with a humidifier that is easy to install and can supply moisture to vegetables and other products to maintain freshness while displaying them.

[Key points of the invention]

In this invention, an ultrasonic humidifier is used, and water such as defrosting water generated in a cooler or the like is collected and supplied to the ultrasonic humidifier for use in humidification.

[Embodiments of the invention]

1 and 2 show an embodiment of the invention. In the figure, reference numeral 1 denotes a main body case that has an opening 1a for taking out products on the front, and is composed of an outer box 2 made of a heat insulating wall and an inner box 8 whose inner side forms a display room 4. A cold air circulation path 5 is formed between the box 8 and the box 8 . The cold air circulation path 5 has both ends facing the opening 1a and is open vertically facing each other, and has a Suita port 5a and a suction port 5 provided with an air regulating fluid.
b, and a fan 6, a cooler 7, and a defrosting heater 8 are arranged inside. The display room 4 is divided into upper and lower sections by shelves 9, and products such as vegetables and fruits are displayed therein.

10 is a fluorescent lamp that illuminates the front of the case and the interior of the room.

11 is an ultrasonic humidifier installed on the upper surface of the main body case 1; 12 is a water receiver installed below the cooler 7 to collect defrosting water generated in the cooler 7; and 13 is an ultrasonic humidifier with a suction port for water. Uke 1
14 is a sterilizing filter that is installed in the middle of the suction pipe 11B and purifies water with activated carbon or the like; 15 is an ultrasonic humidifier 11B; This is a humidifying pipe that is connected to the discharge port of the sonic humidifier 11 and whose tip 15a opens into the display room.

In the above configuration, during cooling operation, indoor air is sucked into the cold air circulation path 5 from the suction port 5b by the fan 6,
It is circulated as shown by arrow A.

This air passes through the cooler 7 and becomes a dehumidified and cooled cold airflow that blows out from the Suita exit 5a.This cold airflow forms an air curtain 17 in the opening 1a, which insulates the display room from outside air and partially cools it. Air current flows through the display room to cool and keep the room cool. In order to prevent the product from drying out due to the cold air flow, the ultrasonic humidifier 11 supplies water to a water tank (not shown) built in the ultrasonic humidifier 11, either continuously or intermittently depending on the product. be driven. The water in the water tank is sprayed into the display room in the form of mist from the opening at the tip of the humidifying vibrator 15, and the products are displayed and refrigerated while maintaining their freshness.

While the cooling operation is continued, a defrosting operation is performed at appropriate intervals, for example, several times a day, in order to cause moisture in the air to condense on the surface of the cooler 7, forming frost, and reducing the cooling capacity. be exposed.

During defrosting operation, the cooler 7 is stopped and the heater 8 is turned off.
is energized. However, the fan 6 causes the heater 8
The heated air is circulated through the cold air circulation path.

The repaired water in the cooler 7 is melted by the warm air, becomes defrost water, and is collected in the water receiver 12. The water receiver 12 stores the amount of water necessary to supply water to the ultrasonic humidifier 11,
Any more water is sent from the drain port 12a to an evaporating dish attached to a condenser (not shown), where it is evaporated. Upon completion of defrosting, the operation is switched back to cooling operation.

- When the water level of the water tank of the ultrasonic humidifier 11 reaches the lower limit, the pump 13 is operated by the operation of the attached float switch, and the water in the water receiver 12 is supplied through the sterilizing filter 14, and the water level When the water reaches the upper limit, the water supply is stopped and a predetermined amount of water is always stored. In the case of the embodiment, defrosting water is generated in one defrosting operation at a rate of 5-toa, or 20-60 liters per day, and the water receptacle 12 used is one capable of storing 40 liters of water. Also ultrasonic humidifier 11++
hkt lrJ engineering↓-furrow 1 top 1 vomitus k1. n/I Shizuku Sufficiently covered by Yuwa IA Shimozu. Therefore, the refrigerated open showcase does not require external piping for supplying water to the ultrasonic humidifier 11. Furthermore, by installing a humidifier that was conventionally installed in the display room on the top surface of the main body case 1, the display room can be used effectively and the product display effect can be made more effective.

〔Effect of the invention〕

According to this invention, in addition to using an ultrasonic humidifier as a humidifying means for humidifying products in a display room, a water receptacle for collecting water such as defrosting water generated from a cooler, etc., and a water receptacle for collecting water such as defrosting water generated from a cooler etc. The product is equipped with a purification means and a pump that purifies the water and sends it to the ultrasonic humidifier, so the product is always appropriately humidified and displayed and refrigerated while maintaining its freshness.Additionally, there is no need for water supply piping to the humidifier during installation. It is possible to provide a refrigerated open showcase with a humidifier that is easy to install.
