According to the present invention, when the installation target is a window of a house, a facility, or the like, a plastic hollow plate is disposed on the glass on the indoor side of the window, and the position is opposed to the position of the inner magnet in one of the through holes. An external magnet or a ferromagnetic material is arranged on the window glass from the outdoor side at a position where the external magnet or ferromagnetic material is to be placed. Alternatively, when the installation target is a steel entrance door of an apartment or the like, a plastic hollow plate is arranged on the entrance door. As described above, by installing the heat insulating panel according to the present invention on the window or the door, the heat insulating effect of the window can be enhanced and the occurrence of dew can be suppressed.

Further, according to the present invention, since the installation is completed by attracting the magnet to a window or the like using a magnet, there is no need to perform a special installation work, which is convenient.

In addition, since the present invention can be installed and removed on a daily basis because the installation is completed simply by attracting it to a window or the like using a magnet, it is possible to easily clean the window or the like to which the present invention is attached. Can be.

(Embodiment 1)
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a longitudinal sectional view showing a use state of the heat insulating panel A of the first embodiment, and shows a state in which the plastic hollow plate 1 of the heat insulating panel A is sucked and fixed to the glass 5 of the window.

<Configuration of Insulated Panel A>
The heat insulating panel A is mainly composed of a plastic hollow plate 1, an inner magnet 2, and an outer magnet 3. The plastic hollow plate 1 of the heat insulation panel A includes an inner magnet 2 slidably provided in one of a plurality of through holes 14 extending vertically in the plastic hollow plate 1, and an outer side of the plastic hollow plate 1. Then, it is attracted and fixed to the window glass 5 by the magnetic force generated between the inner magnet 2 and the outer magnet 3 provided facing the inner magnet 2.

As shown in FIG. 2, the plastic hollow plate 1 is a thin plate having a substantially square front surface. In the present embodiment, the plastic hollow plate 1 has a configuration in which the front is substantially square, but the present invention is not limited to this configuration. For example, the plastic hollow plate 1 may have a configuration in which the front has a substantially rectangular shape. Is also good. That is, the shape and size of the plastic hollow plate 1 can be appropriately changed according to the shape of the window glass 5 to be sucked and fixed.

As shown in FIGS. 2 and 3, along the outer periphery of the plastic hollow plate 1, there is provided an edge member 11 having a substantially L-shaped horizontal cross section (= cross section). The rim member 11 is attached to four sides for reinforcement so that the plastic hollow plate 1 does not warp or bend. Therefore, the rim member 11 has some rigidity, for example, is made of plastic.

As shown in FIG. 3, the rim material 11 has a substantially L-shaped cross section in the horizontal direction (horizontal direction), and the edge material 11 is compared with the plastic hollow plate 1 with respect to the surface of the window glass 5 to be sucked and fixed. Does not protrude. Therefore, even if the plastic hollow plate 1 is attracted to the window glass 5, no gap is formed between the window glass 5 and the plastic hollow plate 1. If there is a gap between the plastic hollow plate 1 and the window glass 5, dew condensation occurs due to the air in the gap. However, by adsorbing the plastic hollow plate 1 to the window glass 5 without any gap, the air in the gap can be eliminated and the occurrence of dew condensation can be prevented.

As shown in FIGS. 3 and 4, a plurality of plate-shaped ribs (= ribs) 13 are vertically provided between two parallel plate-shaped members 12 on the plastic hollow plate 1. Has been. The plastic hollow plate 1 is integrated by two plate-like members 12 and a plurality of ribs 13 of the plate-like member.

In addition, a plurality of ribs (= ribs) 13 of the plate-like body are vertically provided and partitioned between two parallel plate-like bodies 12, so that the plastic hollow plate 1 has a plastic hollow. A plurality of rectangular parallelepiped through-holes 14 extending in the vertical direction of the plate 1 are formed (in the present embodiment shown in FIGS. 3 and 4, thirteen through-holes 14 are formed).

It is desirable that the plastic hollow plate 1 and the edge material 11 be substantially transparent. This is because, when it is installed on the window glass 5, it does not block the lighting of the window glass 5 and is convenient. However, the plastic hollow plate 1 and the edge material 11 are not limited to substantially transparent ones. For example, a colored panel may be used. Alternatively, the surface of the plastic hollow plate 1 and the edge material 11 may be processed to enhance the effect of blocking ultraviolet rays, heat, and the like. For example, a configuration may be adopted in which a metal film such as zinc oxide or silver is coated to make “Low-e specification” to enhance the heat shielding / insulating effect. Further, the plastic hollow plate 1 and the edge material may be coated with a UV cutting agent to enhance the effect of blocking ultraviolet rays.

Further, the plastic hollow plate 1 is preferably a polycarbonate (= polycarbonate) hollow plate. This is because polycarbonate hollow plates are now widely used as general-purpose materials, are easily available, and have reduced prices. Further, the polycarbonate hollow plate having a thickness of about 4 (mm) to about 10 (mm) has a high heat insulating performance and a high transparency. This is because it becomes a window having a heat insulating function.

Further, in the present embodiment, the configuration in which the rim material 11 is provided on the entire outer periphery of the plastic hollow plate 1 has been described, but the present invention is not limited to this configuration. For example, the edge material 11 may be provided at the upper and lower ends of the outer periphery of the plastic hollow plate 1 in order to close the openings of the through holes 14 at the upper and lower ends of the plastic hollow plate 1. That is, a configuration in which the rim material 11 is provided on a part of the outer periphery of the plastic hollow plate 1 may be adopted.

Further, in the present embodiment, a configuration is shown in which the opening of each through-hole 14 of the plastic hollow plate 1 is closed by the rim material 11, but the present invention is not limited to this configuration. The opening of each through-hole 14 at the upper end and the lower end of the plastic hollow plate 1 may be entirely closed with a tape or a plate-like body. Alternatively, of the openings of the respective through holes 14 at the upper end and the lower end of the plastic hollow plate 1, only the opening of the through hole 14 provided with the inner magnet 2 is closed with a tape or a plate-like body. It is good.

The inner magnet 2 is slidably provided in one of the through holes 14 as shown in FIG. In FIG. 4, among the through holes 14 of the plastic hollow plate 1, two, one, and two inner magnets 2 are provided in three through holes 14 such as a left portion, a substantially central portion, and a right portion. Are provided respectively. As described above, in the case of the configuration in which the inner magnet 2 is provided in the through hole 14 at the substantially central portion, the size of the plastic hollow plate 1 is large and warps, and the substantially central portion of the plastic hollow plate 1 floats. In this case, the floating state can be suppressed, the plastic hollow plate 1 can be brought into close contact with the window glass 5, and the gap between the window glass 5 and the plastic hollow plate 1 can be eliminated. Therefore, the air in the gap can be eliminated, and the occurrence of dew condensation can be more effectively prevented.

Further, since the inner magnet 2 is configured to be slidably provided in any of the through holes 14, that is, the inner magnet 2 is moved so that the inner magnet 2 in the through hole 14 can be moved up and down. The vertical and horizontal dimensions must be smaller than the vertical and horizontal dimensions of the through hole 14.

The material of the inner magnet 2 is, for example, a neodymium magnet. However, the present invention is not limited to this configuration, and the material of the inner magnet 2 may be any of a ferrite magnet, a samarium-cobalt magnet, and an alnico magnet. That is, the inner magnet 2 may have any configuration as long as the plastic hollow plate 1 can be attracted and fixed to the window glass 5 by magnetic force using the plurality of inner magnets 2.

In this embodiment, as shown in FIG. 4, the inner magnet 2 is inserted into three through holes 14 such as a left portion, a substantially central portion, and a right portion of the through holes 14 of the plastic hollow plate 1. Although the configuration in which two, one, and two are provided is shown, the present invention is not limited to this configuration. The number of the inner magnets 2 to be used, and in which through-holes 14 the inner magnets 2 are provided, depends on the size of the window glass 5 on which the heat insulating panel A is installed, the state of attraction between the inner magnets 2 and the outer magnets 3. It can be appropriately selected according to the conditions.

Alternatively, a configuration in which the inner magnet 2 is used by winding a tape, cloth, or the like so as not to move in the through hole 14 may be used. For example, from the four corners of the plastic hollow plate 1 (= the upper end and the lower end of the left and right through holes 14), the inner magnets 2 each having a thickness increased by winding a tape, cloth, etc. 2 is clogged near the upper end or lower end of the through hole 14. From the upper end or lower end of the through hole 14 at the substantially central portion of the plastic hollow plate 1, a normal inner magnet 2 not wound with tape, cloth, or the like is inserted. Thereafter, the edge material 11 is attached, and the upper and lower ends of each through hole 14 are closed. When installing the heat insulating panel A on the window glass 5, the inner magnet 2 provided in the through hole 14 at the substantially central portion of the plastic hollow plate 1 is shifted while being attracted to the outer magnet 3, The inner magnet 2 is disposed substantially at the center of the hollow plate 1. Such a configuration may be adopted.

The outer magnet 3 is used in correspondence with the inner magnet 2 via the plastic hollow plate 1 (from the outside of the plastic hollow plate 1). For example, in the present embodiment shown in FIG. 4, since five inner magnets 2 are used, five outer magnets 3 are also used correspondingly. Further, since the inner magnet 2 and the outer magnet 3 need to be attracted, it is needless to say that the polarities of the inner magnet 2 and the outer magnet 3 facing the inner magnet 2 need to be different.

Further, the material of the outer magnet 3 may be, for example, any of a ferrite magnet, a samarium-cobalt magnet, and an alnico magnet. However, usually, a magnet of the same type and substantially the same size as the inner magnet 2 is used because of its magnetic force and ease of use. Used as magnet 3.

In the present embodiment, the configuration in which the outer magnet 3 is used corresponding to the inner magnet 2 has been described, but the present invention is not limited to this configuration. Any structure may be used as long as the plastic hollow plate 1 can be attracted to the window glass 5 by a magnetic force. Therefore, for either the inner magnet 2 or the outer magnet 3, a ferromagnetic material (for example, A configuration in which matching spins are aligned in the same direction and have a large magnetic moment as a whole) may be used.

<Thickness of insulation panel A>
Next, the thickness of the heat insulating panel A will be described. The thickness of the plastic hollow plate 1 is desirably about 4 (mm), including the thickness of the edge material 11. Therefore, the thickness of the inner magnet 2 slidably provided in any of the through holes 14 of the plastic hollow plate 1 is desirably about 2 (mm) in accordance with the thickness of the plastic hollow plate 1. If a magnet of the same type and substantially the same size as the inner magnet 2 is used for the outer magnet 3, the thickness of the outer magnet 3 is desirably about 2 (mm).

Therefore, in the window glass 5 on which the heat insulating panel A is installed, the thickness on the indoor side where the plastic hollow plate 1 is installed increases by about 4 (mm), and the thickness on the outdoor side where the external magnet 3 is installed is increased. Increases by about 2 (mm). If the thickness is increased to such an extent, as shown in FIG. 5, a sliding window (= two or more windows are horizontally moved on rails 52 of two or more parallel windows to open and close). In FIG. 5, even if the heat insulating panel A is installed on each glass 5 of two windows, the windows can be opened and closed without any trouble without being caught, which is convenient.

<Procedure for adsorption and fixing of heat insulation panel A>
The plastic hollow plate 1 of the heat insulation panel A is placed from the indoor side on the window glass 5 to be installed. Then, the outer magnet 3 is arranged on the window glass 5 from the outdoor side at a position facing the position of the inner magnet 2 in one of the through holes 14. Then, the inner magnet 2 and the outer magnet 3 are attracted. When the inner magnet 2 and the outer magnet 3 are attracted by magnetic force, the plastic hollow plate 1 is attracted and fixed to the window glass 5. When the positions of the inner magnet 2 and the outer magnet 3 are changed, the outer magnet 3 is shifted vertically.

The above procedure may be performed by one user such as a worker, or may be performed by a plurality of workers or the like. For example, when the size of the window is small, a user such as an operator holds the plastic hollow plate 1 with one hand from the indoor side, puts out the other hand outdoors, and penetrates the outer magnet 3. It is arranged on the window glass 5 facing the position of the inner magnet 2 in the hole 14. Alternatively, a user such as an operator presses the plastic hollow plate 1 from the indoor side. Then, a user such as another worker places the outer magnet 3 on the window glass 5 facing the position of the inner magnet 2 in the through hole 14 from the outdoor side.

Thus, the heat insulation panel A can be installed by a simple operation without performing any special installation work, which is convenient.

Moreover, since the installation of the heat insulation panel A is completed only by adsorbing it on the window glass 5 using the inner magnet 2 and the outer magnet 3, attachment and detachment can be performed on a daily basis, and the target window can be cleaned. Easy to do.

Furthermore, since the heat insulating panel A is configured to be installed on the window glass 5 using the inner magnet 2 and the outer magnet 3, when the window is removed from the window, a stain on the window such as tape or adhesive remains. Not a convenience.

<Performance experiment of thermal insulation panel A>
Next, a performance experiment performed on the heat insulating panel A will be described. FIG. 6 is a plan view of the device D used in this performance experiment.

Ice water was poured into the acrylic water tank 6 at the center (shaded area in FIG. 6) to create an outdoor environment at a midwinter temperature. And the indoor environment B which attached the heat insulation panel A to the glass 5 of the window was created in the left part. Further, an indoor environment C to which the heat insulating panel A was not attached was made only with the window glass 5 on the right side.

In addition, the thermometer 7 for measuring the temperature is placed in the ice water of the acrylic water tank 6, approximately in the center of the indoor environment B, the surface of the heat insulating panel A in the indoor environment B, approximately the center of the indoor environment C, and the indoor environment C On the surface of the glass 5 of each of the windows. And the temperature was measured with the thermometer 7 provided in each place.

As compared with the temperature of the surface of the glass 5 of the window of the indoor environment C, the higher the temperature of the surface of the heat insulating panel A, the higher the heat insulating effect and the higher the dew condensation preventing effect.

FIG. 7 is a graph showing a temperature change on the surface of the window glass 5 in the indoor environment C and a temperature change on the surface of the heat insulating panel A in the indoor environment B with respect to a change in ice water temperature. When the plotted points are “diamonds”, the temperature changes on the surface of the heat insulation panel A in the indoor environment B are shown, and when the plotted points are “squares”, the windows in the indoor environment C are windows. 3 shows a temperature change on the surface of the glass 5. Note that the plotted points having a “triangle” indicate a temperature change of ice water in the acrylic water tank 6.

According to the graph of the temperature change shown in FIG. 7, the temperature change becomes stable about 25 minutes after the start of the measurement, and as a result, the temperature of the heat insulating panel A in the indoor environment B becomes “about 13 (° C.)” and the temperature of the indoor environment C becomes The temperature of the window glass 5 is “about 8 (° C.)”, the temperature of the ice water is “about 6 (° C.)”, and the temperature difference between the heat insulating panel A and the window glass 5 is “about 5 (° C.)”. Became. In other words, according to the results of this experiment, the temperature of the window glass 5 was about 8 (° C.) in the mid-winter environment where the outside air temperature was “about 6 (° C.)”, but the heat insulating panel A was installed. In this case, it was "about 13 (° C.)".

These results are confirmed in the "pneumatic chart". The "pneumatic chart" is a chart in which dry-bulb / wet-bulb temperature, dew point temperature, absolute / relative humidity, enthalpy, etc. are entered on the chart, and any two values are determined from among them. FIG. 3 is a diagram that allows all state values to be easily obtained, and is well known in the field of air conditioning.

In the case of the indoor environment C where only the window glass 5 does not have the heat insulating panel A, the dew point temperature (= if the humid air is gradually cooled, the saturation occurs at a certain temperature, and the water vapor in the air changes to a liquid. The temperature of the window glass 5 becomes “about 8 (° C.)”. Therefore, when the temperature of the indoor environment C is “20 (° C.)” and the humidity is “50 (%)” or more, dew condensation occurs on the glass 5 of the window of the indoor environment C.

On the other hand, in the case of the indoor environment B in which the heat insulating panel A is installed on the window glass 5, the dew point temperature is “about 13 (° C.)” of the heat insulating panel A. Therefore, when the temperature of the indoor environment B is “20 (° C.)”, the condensation does not occur on the heat insulating panel A unless the humidity exceeds “about 65 (%)”. Further, when the humidity is “50 (%)”, if the temperature of the indoor environment B does not exceed “about 24 (° C.)”, no dew condensation occurs on the heat insulating panel A.

That is, the dew point temperature is higher in the indoor environment B where the heat insulating panel A is installed than in the indoor environment C where the heat insulating panel A is not installed on the window glass 5. Therefore, it can be seen that the heat insulating panel A has a heat insulating effect and a high dew condensation preventing effect.

<Mounting experiment of thermal insulation panel A>
The heat insulating panel A was installed on the glass 5 of the window of the apartment, and confirmed by an infrared thermometer and thermography. Specifically, as shown in FIG. 8, the heat insulating panel A was installed on the lower window glass 5 that was vertically divided into two parts by the window sash 51. The glass 5 of the upper window remains intact.

The surface temperature of the glass 5 on the upper window was measured by an infrared thermometer and found to be "7 (° C.)". The surface temperature of the heat insulating panel A installed on the lower window glass 5 was measured by an infrared thermometer and found to be "11 (° C)".

In addition, when the image was taken by thermography, the upper window glass 5 was not displayed in red because the temperature was low, but the lower heat insulating panel A was displayed in red because the temperature was high.

Further, when the laundry was dried to raise the humidity to promote the dew condensation, dew condensation occurred on one surface of the upper window glass 5, but no dew condensation occurred on the lower window glass 5. Was.

That is, the dew point temperature of the window glass 5 on which the heat insulating panel A is installed is higher than that of the window glass 5 on which the heat insulating panel A is not installed. Therefore, it can be seen that the heat insulating panel A has a heat insulating effect and a high dew condensation preventing effect.

<Modification>
In the present embodiment, a configuration is shown in which a plurality of through holes 14 of the plastic hollow plate 1 are provided in parallel in the vertical direction of the plastic hollow plate 1, but the present invention is not limited to this configuration. For example, a configuration in which a plurality of through holes 14 of the plastic hollow plate 1 are provided in parallel in the left-right direction of the plastic hollow plate 1 may be employed.

Further, in the present embodiment, the configuration in which the heat insulating panel A is applied to the window glass 5 has been described, but the configuration is not limited to this configuration. For example, the heat insulation panel can be applied to a steel entrance door.

In condominiums that have been built for several decades or more, steel entrance doors are often used. Steel entrance doors have a problem that dew condensation occurs frequently and the entrance is cold. By installing the heat insulating panel according to the present invention in such a steel entrance door, it is possible to prevent the occurrence of dew condensation and to shut off outdoor cool air.

Since the steel entrance door is a ferromagnetic material, the plastic hollow plate 1 is attracted to the entrance door by using the inner magnet 2 without using the outer magnet 3. The movement of the inner magnet 2 provided in the through hole 14 of the plastic hollow plate 1 is performed from the indoor side by using the outer magnet 3 via the plastic hollow plate 1.

<Use of the present invention>
Since the heat insulating panel according to the present invention has excellent heat insulating performance, it is installed on non-insulating windows of municipal housing, kindergartens, nursing homes and other public facilities, including non-insulating windows of condominiums and detached houses. Thereby, it is possible to take measures against the cold at a lower price than installing a double window sash or replacing with a double glass.

To prevent heat shock in dressing rooms, bathrooms, toilets, etc., which is the most common cause of death at home. It is very effective to install the heat insulating panel according to the present invention in a window or a door of a dressing room or a bathroom.

Condominiums with high airtightness but non-insulated windows are likely to cause condensation on the windows, causing sash decay and mold. By doing so, the occurrence of condensation can be suppressed.

Even if houses and facilities are old and cold, but can not be renovated at a large cost, by installing the heat insulating panel according to the present invention in each window, it will be quite warm houses, facilities, etc. .
