Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a curved mirror having a mirror surface anti-fog function.

[0002]

[Prior Art]

 Conventionally, curved mirrors installed at the corners of roads are constructed by bending stainless steel, acrylic plate, glass mirror plate, etc. and mirror-finishing the surface of the mirror plate, and attaching the back cover, which is a frame for mounting columns, etc. Has been done.

[0003]

[Problems to be solved by the device]

 However, in the conventional curved mirror configured as described above, the surface temperature of the end plate becomes low as it cools at night and early in the morning, especially at dawn. However, the mirror surface often becomes cloudy. As described above, if the mirror surface becomes cloudy, the visibility in the mirror surface will deteriorate, which naturally hinders safe traffic.

An object of the present invention is to provide the above-described conventional curve mirror with a function of preventing dew condensation on the mirror surface, and thereby prevent fogging of the mirror surface due to cooling of outside air. .

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention forms a space between the lid and the lid on the back side of the end plate, and stores a gel heat storage agent in this space via a space retaining material. A container is installed inside, and a gap is formed between the heat storage container and the end plate by a gap holding material.

[0006]

[Action]

 According to the above means, in the space formed between the end plate and the lid, the gap holding material is applied to the back surface of the end plate, and a large amount of heat is stored on the back side of the gap holding material. A heat storage container containing a gel heat storage agent is provided. The above-mentioned space holding material is arranged with a predetermined space between the end plate and the heat storage container to form a space (air layer) between them. Then, due to the temperature rise during the daytime, heat energy is absorbed and stored in the gel heat storage agent in the heat storage container, and this heat energy is gradually released from the nighttime as the temperature decreases in the morning. The heat released from the heat storage container warms the end plate to a temperature higher than the outside air through the air gap (air layer) to prevent dew condensation on the mirror surface.

In addition, the space retaining material forms a space between the end plate and the heat storage container to form an air layer between the heat storage container and the end plate, and this air layer allows heat energy stored in the heat storage container to be absorbed. It prevents the heat from being directly emitted to the end plate and maintains stable heat radiation for a long time. In addition, when the heat accumulated in the heat storage container bottoms out due to strong cooling, the end plate heats as the temperature rises after sunrise.At this time, the air layer described above causes the heat from the end plate to reach the heat storage container. Cut off the flow to accelerate the temperature rise on the mirror surface.

[0008]

[Effect of the device]

 As described above, according to the present invention, on the back surface of the end plate, a space holding material and a heat storage container containing a gel heat storage agent having a large amount of heat storage and good heat dissipation characteristics are arranged, and the end plate is provided through the space holding material. Since a gap is formed between the heat storage container and the heat storage container, more heat energy is stored in the gel heat storage agent during the day, and this heat energy is stored in the time zone when the temperature decreases from night to morning. The mirror plate can be warmed while gently radiating heat through the void portion formed by the void retaining material, that is, the warmed air layer, which can effectively prevent fogging of the mirror surface due to cooling.

Further, on a day of strong cold, the heat storage by the heat storage container bottoms out, so that dew condensation will inevitably occur on the mirror surface. In this case, as the temperature rises after sunrise and the dew condensation disappears, the air layer created by the air gap retainer blocks the heat flow from the end plate to the heat storage container and causes a mirror surface. Since the temperature rise of the mirror is accelerated, the dew condensation on the mirror surface can be quickly eliminated.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. The curve mirror shown in FIGS. 1 and 2 is a mirror plate having a form well known in the technical field of this type, for example, a mirror plate 1 formed by curving a circular stainless plate in a convex shape. Alternatively, it is detachably provided, and the outer peripheral portions of the both 1 and 2 are joined to be integrally formed, and a space 3 is formed between the end plate 1 and the lid body 2, and a space holding member 4 is interposed in the space 3. Then, the end plate 1 side is provided with a space 3a, and the lid 2 side is provided with a heat storage container 5 containing a gel heat storage agent 5a and a heat insulating material 6, respectively.

The space holding material 4 is formed, for example, so as to partition the space 3 into the space 3 a side and the heat storage container 5 side or hold (support) the heat storage container 5 and form the space 3 a on the front surface thereof. Any shape such as a plate shape, a perforated plate shape, a mesh shape, a plate shape with a support piece formed, a support frame shape, etc., made of synthetic resin, hard paper, woven or knitted cloth, metal, etc. may be used. It is provided so as to face the back surface or the front surface of the heat storage container 5, and a space 3 a is formed between the space holding material 4 and the end plate 1. It is also possible to use a honeycomb structure having an air layer of a required thickness by itself, an air cap sheet used as a cushioning material during packaging, etc. The air layer becomes the void 3a. Further, in the case where it has a heat conductivity like an iron plate, it is possible to prevent local heat leakage by providing a heat insulating packing at the outer peripheral edge portion or a predetermined portion thereof.

The heat storage container 5 provided on the back side of the space holding material 4 is formed so as to fill the remaining space of the space 3 and contains the gel heat storage agent 5a therein. As the gel heat storage agent 5a, for example, a poval gel or a water-absorbent polymer used by being filled in a cooling bag used as a water pillow or a cooling tool of a cooler box is used. These gel-like heat storage agents 5a have a large amount of heat storage and have the characteristics that heat is released slowly and stably, and therefore they are also suitable as a heat storage material to be used as in the present invention, and a container for storing them. Is aluminum foil, plastic film, or a laminate of these.

The end plate 1 and the heat storage container 5 described above are arranged with a predetermined gap by the gap holding material 4, and the both 1 and 5 face each other through the air layer formed by the gap 3a.

A heat insulating material 6 made of urethane foam, styrofoam, or the like is interposed on the back side of the heat storage container 5 described above to prevent unnecessary heat dissipation from the heat storage container 5 that has accumulated heat. The heat retention efficiency can be improved.

In the curved mirror configured as described above, the heat energy is absorbed and stored in the gel heat storage agent 5a in the heat storage container 5 due to the temperature rise in the daytime, and this heat energy causes a temperature drop from night to morning. The heat is gradually dissipated accordingly. Then, the heat released from the heat storage container 5 warms the end plate 1 to a temperature close to or higher than the outside air temperature through the gap 3a formed by the gap holding material 4 to prevent dew condensation on the mirror surface 1a.

As described above, the space holding material 4 forms the space 3a between the end plate 1 and the heat storage container 5, and the space creates an air layer that can be heated by the heat storage container 5. As a result, the heat energy stored in the heat storage container 5 is prevented from being directly emitted to the end plate 1, and stable heat dissipation can be maintained.

However, the curved mirror described above can efficiently store a large amount of heat energy during the daytime by using the gel-like heat storage agent 5a that has a large amount of heat storage and excellent heat dissipation characteristics. The generated thermal energy can be released slowly and stably through the air layer of the void 3a formed by the void holding material 4 in the time zone when the temperature decreases from night to morning. It is possible to effectively continue the heat retention of the end plate 1 during the time when dew condensation is likely to occur and effectively prevent the fogging of the mirror surface 1a due to dew condensation.

Further, since the heat storage by the heat storage container 5 reaches the bottom on a day of strong cooling, dew condensation is inevitably generated on the mirror surface 1a. In this case, as the temperature rises after sunrise, the end plate 1a is heated and the dew condensation gradually disappears. However, the air layer formed by the space 3a formed by the space holding member 4 is Since the heat flow from the heat storage container 5 to the heat storage container 5 is blocked and the temperature rise of the mirror surface 1a is accelerated, the dew condensation on the mirror surface 1a can be quickly eliminated.
