Description

[Detailed description of the invention] This invention is applicable to glass-containing doors that open and close openings, such as refrigerator-freezers, refrigerator-freezer doors, and opening/closing windows and doors of buildings. This relates to improvements to doors.

Two or more pieces of glass are placed side by side with a uniform gap between them,
The gap is filled with dry gas at a pressure close to outside pressure, and the surrounding area is sealed to meet the Japanese Industrial Standards.
JISR3209 calls it double-glazed glass, and it stipulates that double-glazed glass is to be used primarily for the purpose of insulation in buildings, refrigerator/freezer cases, railway vehicle windows, etc. It's called layered glass.

By the way, in the case of double-glazed glass in refrigerators and freezers, when the internal temperature is below freezing and the outside temperature is high, the space between the two glasses is relatively cold, so the outer (higher temperature side) glass becomes colder. Therefore, moisture in the outside air adheres to the glass and condenses, making it translucent or opaque, and it is extremely troublesome to wipe off the fog from the glass every time you look through the inside of the refrigerator.

In order to eliminate the above-mentioned complications, there has been a proposal to blow hot air onto the outer surface of the glass on the high temperature side, but this blowing of hot air has the disadvantage of causing discomfort when opening and closing the door.

This invention solves the above-mentioned problems with double glazing, and its purpose is to provide a double glazing that allows hot air to be blown inside the double glazing without reducing the insulating effect of the double glazing.

That is, in order to achieve the above object, in this invention, two pieces of glass are fitted into a peripheral frame so as to face each other, and the space between the two pieces of glass is partitioned into a plurality of chambers by a transparent partition wall having heat insulating properties. A heated air supply/exhaust port is provided in the peripheral frame, and the air supply port communicates with one side of the outermost compartment on the high temperature side, and the exhaust port communicates with the other side of the compartment. .

As the heated air, residual heat air from a refrigeration cycle system or a condenser of a freezer/refrigerator can be used.
In this case, it is preferable that the above-mentioned air supply/exhaust port also serves as a receiving hole on one side of the upper and lower edge peripheral frame of the double-glazed glass, which corresponds to a pivot that is a hinge, and that the pivot that is the hinge is configured as a pipe.

With double-glazed glass configured in this way, by circulating high-temperature air to the outermost compartment on the high-temperature side through the air supply/exhaust port, cooling of the surface glass of the compartment is prevented and condensation does not occur. do not have.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

In FIG. 1, 1 is a peripheral frame and 2 is a glass fitted into the peripheral frame 1, but as shown enlarged in FIG. 2, two pieces of glass 2, 2a are placed opposite each other, A transparent partition wall 3 made of glass, a plastic plate, a plastic sheet, etc. with heat insulating properties is further arranged between the two glasses to divide the chambers into a plurality of chambers 4a and 4b.As will be described later, one of the chambers 4a on the high temperature side is An air supply port 5 for supplying heated air is in communication with one side, and an exhaust port 6 for exhausting the heated air is in communication with the other side.

The heated air to be supplied can be residual heat air from a refrigeration cycle system or condenser in a refrigeration equipment. 7 indicates a box in which a refrigeration cycle and a condenser are installed.

The air supply port 5 and the discharge port are receiving holes made of a pipe that correspond to the pivot that is the hinge of the door.Therefore, the pivot (not shown) is also a pipe, and on the air supply side, the forced exhaust from the box 7 is connected to the pipe that is the pivot. The pipes are connected.

In the figure, 8a is a receiving hole that is the air supply port 5, that is, a fixture for the pipe 9, and 8b is a receiving hole that is the exhaust port 6, that is, a fixture for the pipe. Further, 10 is an interval regulating frame, 11 is a glass holding frame, and 12 is an air inlet hole formed in the lower side frame of the interval regulating frame and the glass holding frame on the side of the compartment 4a, and the same is also provided in the upper side frame. Although an exhaust hole is formed, it is not shown in the figure.
The supply and exhaust ports 5 and 6 are connected to the compartment 4a through the exhaust holes.
communicate with. Further, a desiccant is filled in the space regulating frame 10, and a sealing material is filled between the space regulating frame 10 and the glass holding frame 11, but these are not shown. 13
14 is a gasket, 14 is a magnet, 15 is a corner metal fitting of the frame, and 16 is a handle for double-glazed glass.

In the embodiment configured as described above, heated air flows into the compartment 4a from the air supply port 5 through the inlet hole 12, and flows out from the exhaust port 6 through the exhaust hole, thereby forming the compartment 4a. It's warm inside. Therefore, no dew condensation occurs on the surface glass 2 of the compartment a.
On the other hand, the interior of the refrigerator is divided by compartments 4b and is insulated, so it is not heated by the heated air. That is, the circulation of the heated air does not affect the temperature inside the refrigerator.

Since this device is configured as described above, the heated air warms the glass on the high temperature side, so moisture does not condense, and since the heated air is supplied inside the double-glazed glass, the glass on the high-temperature side is heated. This has the advantage that there is no discomfort caused by hot air blowing out, which is conventionally seen when opening and closing glass.

In addition, residual heated air from the refrigeration cycle system or condenser is used to supply and discharge heated air to the outermost compartment on the high temperature side between the two panes of glass, and the heated air is supplied to the outermost compartment on the high temperature side. By using the exhaust port as a receiving hole on one side of the upper and lower edges of the door that corresponds to the pivot that is the hinge, and making the pivot that is the hinge a pipe, a heated air supply/discharge mechanism to the outermost compartment of the double-glazed glass is created. It has the advantage of being extremely easy to form.

Furthermore, even if heated air is supplied to the outermost compartment, there is no effect on the temperature inside the compartment divided by the double-glazed glass.
