2. Description of the Related Art Conventionally, a medicated cold storage of this kind has been known as Shoko 60-.
As disclosed in Japanese Patent No. 21749, a door that opens and closes an opening of a heat insulating box is provided with a window through which the inside of the refrigerator can be seen, and the window of the door is arranged at a predetermined interval. It is composed of two or three glass plates provided and spacers that form the gap between these glass plates. Then, in order to store drugs such as medicines and blood and biological materials in the refrigerator, it is necessary to make it possible to visually check the contents stored in the refrigerator while keeping the refrigerator in a dark room. I was using it.

[0003]

However, since such a medicated cold storage uses colored glass, it is difficult to see the contents stored in the cold storage, and if the color is made lighter to make it easier to see, the influence of light rays or the like will be adversely affected. There was a contradictory problem that it became easy to receive chemicals and the quality of chemicals changed.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a medicated cool box having a window portion in which the stored items can be easily seen and which is excellent in light shielding.

[0005]

According to the present invention, there is provided a medicated cold storage in which a door that opens and closes an opening of a heat insulating box is provided with a window through which the inside of the refrigerator can be seen, and the window of the door is transparent on a wall surface. A first panel formed by enclosing a liquid crystal between a pair of glass plates provided with an electrode film, a second panel formed by a glass plate provided at a distance from the panel, and the space formed between the two panels. The transparent electrode film is formed of a spacer and becomes transparent when electricity is applied to the transparent electrode film, while it is milky white when electricity is not applied to the transparent electrode film.

[0006]

With the above-described structure, the medicated cold storage box of the present invention, for example, in a nurse station in a hospital, when the switch is normally turned off, the window is made milky white to block light rays and the like and prevent deterioration of the stored items. It is possible to prevent the contents from coming into contact with the eyes of the patient or the like, and avoid giving unnecessary pressure to the patient. In addition, when a nurse or the like wants to check the contents stored in the medicated cool box, the window can be made transparent by operating the switch to energize the window, ensuring that the contents are stored without opening the door. I can confirm.

This medicated cool box has a box body 4 in which a heat insulating material 14 is foam-filled between an outer box 1 and an inner box 2, a door body 3 for opening and closing a front opening of the box body, It comprises a cold room 5 formed in the upper part of the box body 4 and a machine room 6 formed in the lower part of the box body 4.

A plurality of shelves 7 for placing articles are installed in the cool room 5. A cool air blowing duct 8 is formed at the back of the cool chamber 5, and a fan 9 and a cooler 10 are housed in this duct.

The machine chamber 6 accommodates a cooling unit including a compressor 11, a condenser 12, a condenser cooling fan 13 and a decompressor (not shown).

The door 3 has a window portion 15 through which the inside of the room can be seen, and this window portion has a transparent electrode film 1 on the wall surface as shown in FIG.
A pair of transparent glass plates 17 and 17 provided with 6, 16;
A spacer 19 forming a predetermined gap 18 between the glass plates 17 and a first panel 22 formed of a normally transparent liquid crystal 21 enclosed in the gap 20, a panel 23 and a gap 23. It is composed of a second panel 25 made of a glass plate 24 provided with a space between them and a spacer 26 for forming the space 23 as an air layer between these two panels 22, 25.

Then, the transparent electrode film 1 of the window portion 15
Reference numerals 6 and 16 are connected to a power source 30 via a connection terminal 27, a switch 28, and an interior lamp 29 for illuminating the cold storage room 5.

In the window portion 15, the liquid crystal 21 is transparent when the switch 28 is turned off, but when the switch 28 is turned on, a voltage is applied to the liquid crystal 21 and the liquid crystal 21 becomes milky white. .. Also, switch O
Since the interior lamp 29 is also turned on by N, the window 15 is made transparent, and at the same time, the articles stored in the cold storage chamber 5 are illuminated.

The switch 28 is provided on the control panel 31 provided on the lower front portion of the box body 4, and the operation switch 3
2 and the heater switch 33 for dew condensation prevention.

The medicated cool box thus constructed has the window 15 of the door 3 and the liquid crystal 21 sealed between a pair of glass plates 17 and 17 having transparent electrode films 16 and 16 on the wall surface. The transparent electrode is formed by a first panel 22, a second panel 25 made of a glass plate provided at a distance 23 from the first panel 22, and a spacer 26 forming the distance 23 between the panels 22 and 25. While the films 16 and 16 are transparent when energized, they are milky white when not energized. For example, in a nurse station in a hospital, when the switch 28 is normally turned off, the window 15 is milky white to shield light rays and the like. It is possible to prevent the deterioration of the object and prevent the stored object from coming into contact with the eyes of the patient or the like, thereby avoiding giving unnecessary pressure to the patient. When a nurse or the like wants to check the contents stored in the medicated cool box, the window 15 can be made transparent by operating the switch 28 to energize the window 15, and the window 3 can be stored without opening it. You can definitely check things. Moreover, since the interior lamp 29 can be turned on at the same time when the switch 28 is energized, the stored items can be easily confirmed.

In addition, this medicated cool box has two
