Description

[Detailed description of the invention] [Industrial application field] This invention relates to a heat-retaining door for a bathroom window that insulates and retains heat of the bathroom window.

[Conventional technology]

Windows installed in bathrooms usually consist only of glass windows, and are not provided with any special heat insulation or heat retention material.
Therefore, when the outside air temperature drops to 0° C. or lower in winter, the temperature inside the bathroom is considerably affected, and at the same time, the temperature of the water inside the bathtub also drops.

As a means of insulating and keeping these windows warm,
One possibility would be to use a conventional window frame and insert an insulating door into it.

[Problem that the invention attempts to solve]

However, since bathroom windows are used to dry the interior of the room when the bathroom is not in use during the day, simply fitting the door in is inconvenient to remove, resulting in the bathroom being unusable. Even if you try to set up a special frame and fit the door into it, the insulating door is about the same size as the window frame, so for example, the U-shaped cross section used for ordinary shoji or glass doors will not fit. Even if you use a structure in which the top and bottom frames have deep cut depths at the top and shallow depths at the bottom, in order to ensure heat insulation, it is important to leave a large space between the door and the frame that receives it. Therefore, it is inconvenient to install and remove it.

The purpose of this invention was made in view of the above-mentioned actual situation, and by simply attaching a combination of a simple frame and a heat-insulating door to a window frame with adhesive,
To provide an easily removable heat-insulating door for a bathroom window.

[Means for solving problems]

As a means to solve the above problems, this invention includes a heat-insulating door frame that is fixed to the inside of the bathroom window frame using an appropriate fixing means such as adhesive, and a certain minute space inside the heat-insulating door frame. The heat-insulating door frame is fitted with a heat-insulating lid formed of an insulating material that fits through the heat-insulating material, and the heat-insulating door frame is provided with ears around the entire back surface, and the cross-sections of the upper and lower sides of the heat-insulating door frame and the heat-insulating lid that face each other are defined as the ears. We adopted a structure in which the structure is inclined downward at the required angle.

[Effect]

In order to obtain the heat-insulating effect when using the bathroom, a heat-insulating lid is fitted into another frame fixed to the bathroom window frame. Normally, when used with the inclined cross section of the inner section facing upward and downward, the heat insulating cover is easily fitted into the frame due to its own weight and is firmly attached to the frame. . Even if there is a slight gap between the heat-insulating lid and the frame, the heat-insulating lid will be pushed diagonally and lightly into the ears provided on the back of the frame due to its own weight, making surface contact.
Air circulation due to temperature differences between indoors and outdoors is largely blocked. Therefore, heat loss due to air circulation and heat transfer due to heat conduction are largely eliminated.

〔Example〕

Embodiments of this invention will be described below with reference to the attached drawings.

Figure 1 shows the entire bathroom window thermal door according to this invention. 1 is a rectangular heat-insulating heat-retaining lid, which has a core made of a heat insulating material made of synthetic resin such as polyurethane or styrofoam, and the outside is made of thin F, R, P.
It is surrounded by a base material (reinforced glass fiber material). 2 is a heat-insulating door frame for attaching the above-mentioned heat-insulating lid to the window frame 6, and is also made of F, R, and P. This frame 2 is fixed to the window frame 6 or the inner wall around it by suitable fixing means such as adhesive 3. Further, the heat-insulating lid 1 is provided with a handle 4, and the heat-insulating door frame 2 is provided with a simple stopper.

As shown in Fig. 2, the cross-sectional shapes of the heat-insulating lid 1 and the heat-insulating door frame 2 are such that their upper and lower parts facing each other are slightly oblique with respect to the horizontal plane when viewed in cross section. The cross section is slanted and extends in parallel, while both sides have a right-angled cross section as shown in FIG. Further, on the back surface of the frame 2, an ear plate 1a is provided around the entire circumference.

A space of less than m/m order is provided around the entire circumference between the heat-insulating lid 1 and the heat-insulating door frame 2, and this space allows the heat-insulating lid 1 to be easily attached to and removed from the heat-insulating door frame 2. It is sufficient to make it as close as possible.

The operation of this embodiment having the above configuration will be explained below.

The heat-insulating door frame 2 attached to the window frame 6 is fixed to the window frame or the surrounding wall with adhesive or the like.
Sufficient airtightness is achieved between the window frame or wall and this heat-insulating door frame 2. A heat-insulating lid 1 is fitted into a heat-insulating door frame 2 while the heat-insulating door is in use. Since the cross-sections of the upper and lower horizontal parts of the heat-retaining lid 1 and the heat-retaining door frame 2 are slightly inclined, the heat-retaining lid 1 abuts against the ear plate 1a on the back side of the frame 2 due to its own weight. The flow of air entering from the side of the window frame is therefore largely blocked by this.

When fitting the heat-insulating lid 1 into the heat-insulating door frame 2, it is preferable to arrange the handle 4 and stopper 5 so that they are upward as shown in the figure, but depending on the situation, they may be arranged so that they are on either the left or right side. The slope of the cross section may also be on the left or right.

Next, the results of actually measuring the effectiveness of this heat-insulating door for bathroom windows when attached to an actual bathroom window will be described below.

The layout of the bathroom used for the measurements is as shown in Figure 4, with 10 being a heating door, 11 being a bathtub, 12 being a washing area, 13 being a dressing room, and 14 being outside. A heat insulating door of the above configuration was installed on the window of this bathroom, and when the changes in the water temperature and room temperature were graphed under various outdoor air conditions, the results shown in Figure 5 were obtained. In this figure, the solid line indicates when a heat-retaining door is used, and the dotted line indicates when it is not used.The high-temperature line of around 40℃ indicates the water temperature, and the low-temperature line of 10 to 20℃ indicates changes in room temperature. There is. As you can see from this graph, when using a heating door, the room temperature rises over time after hot water is supplied to the bathtub, and compared to when the heating door is not used, there is a temperature difference of 4 to 5 degrees Celsius after 40 to 50 minutes. It is occurring. Since the structure around the bathroom uses a gas bath in a typical household, this measurement data was not measured under the same exact conditions, but it is sufficient as material to qualitatively explain the insulation effect of the heat-retaining door. It must be something.

〔effect〕

As explained above, the heat-insulating door for the bathroom according to this invention has a simple and easy-to-handle heat-insulating door frame and a heat-insulating lid whose lower horizontal section is inclined slightly with respect to the horizontal plane. It almost completely blocks cold air from outside from entering through the gap between the window and the window frame, and by insulating the gap with insulation, it also blocks heat transfer from the window glass. death,
A practically sufficient insulation effect can be obtained.

Although the heat-insulating door according to this invention is particularly intended for use in bathrooms, it is obvious that it can be used in a variety of other cases as long as the purpose is to provide insulation for rooms with similar conditions.
