Description

Detailed description of the invention

  In winter rooms, heat radiation from window glass, bathroom window glass, cold air flows into the room from the gaps of windows, walls, floors, tatami mats, doors, etc., and elderly people are related to shields that prevent the body from cooling and getting cold .

  Elderly people are seated at the window of vehicles such as cars, bullet trains, airplanes, ships, etc. in winter, even if the car body is cold-resistant and heated, the seats on the window side are cold and cold during travel, and the shield protects the body from the cold About.

  In elderly people, taking blood pressure-lowering agents and vasodilators that are prescribed to improve coronary blood may interfere with the contraction of the peripheral blood vessels due to the cold, particularly causing hypothermia. (For example, see Non-Patent Document 1)

  The two-stage bed for children placed near the wall has an upper stage of 17 ° C and a lower stage of 15 ° C with a temperature difference of about 2 ° C. Therefore, if there is a temperature difference of 2 ° C., it is a worrisome temperature difference. (For example, see Non-Patent Document 2)

Edited by Mitsukawa Kawashima, “Thermal Residential Thermal Environment of the Elderly”, published by Science and Engineering, June 24, 1994, P.A. 199

  In winter, the vertical temperature distribution of the room temperature is lower at a temperature of 100 cm above the living room than at a height of 1200 cm, and the temperature difference is particularly high in the Tohoku region of Akita and Sendai, up to 14 ° C. (For example, see Non-Patent Document 3)

  A transparent resin plate is attached to the shoji, and an air layer with a thickness of 1.5cm between the shoji paper and the transparent resin is created. Airtightness is maintained, so disaster prevention, sound insulation and heat insulation can be achieved, and the paper can be replaced. In this case, it is disclosed that the transparent resin can be removed. (For example, see Japanese Patent No. 3518578)

  A part of an interior material body installed upright in a room is provided with a space for mounting a sheet heating element in the vertical direction, and the sheet heating element is mounted in the space. Standing interior materials are open to the public. (For example, refer to Japanese Utility Model Publication No. 7-35615)

  There are published lace window materials for heat insulation and soundproofing that are directly pasted on the window glass and the window to which the lace window material is attached. (For example, see Utility Model Registration No. 3087729)

Problems to be solved by the invention

  Since cold air has a higher density than warm air, it sinks below and accumulates in a range of 100 cm from the tatami surface, flows into the room, cools the body, provides a space for cold air to cool, blocks cold air from flowing into the room, There was a problem that I needed to protect my body from the cold.

  In the winter, there was a problem that the temperature at the window and the bathroom could be different due to the window glass, heat dissipation from the aluminum sash, and the gap air, and even if the bath was boiling, the naked body cooled, blood pressure increased, and hypertensive cerebral hemorrhage occurred. .

  Elderly people sit on the window side of vehicles such as cars, bullet trains, airplanes, ships, etc. in winter, even if the car body is heated in a cold-resistant structure, the seats on the window side will cool down and protect the body from cold There was a problem to move to the side seat.

  Older people who regularly use antihypertensive agents get cold and cold when the temperature difference between the window and the room in winter is 2 ° C or more. The cause is heat from the window glass and aluminum sash. There was a problem that the temperature difference in the room was 100cm from the floor and the tatami surface through the gaps between the tatami mats and doors, and the temperature could be changed in the room. (See Table 1 for tatami thermal conductivity)

  The thermal conductivity of the aluminum sash frame is 269 times the thermal conductivity of the plate glass, and since the thermal conductivity is large, the heat is radiated, and cold air accumulates under the frame and flows into the room to lower the temperature. (See Table 1) (for example, see Non-Patent Document 4)

S. Suganuma, “Concept of Insulation for Architecture”, published by Ohmsha, published on May 25, 2004, p. 8

  Plants must be moved indoors because they are warm in the daytime and cold in the nighttime when placed at the window in winter.

  When a folding screen paper or curtain gets wet with moisture or water, the thermal conductivity becomes 25 times that of when it is dried, and the heat insulating property is lowered and it becomes cold. (See Table 2)

Naokata Kitayama, “How to Learn Heat Transfer Engineering”, published by Ohmsha, published on February 5, 2007, p. 21

  The lower ends of the curtains and blinds have a gap between the floor and the tatami surface, so that cold air flows into the room and the body gets cold and cold.

  There is a gap between the sides of the screen and the windows and shoji doors, and cold air flows into the room and the body gets cold.

  The renovation of the double glass door structure requires expensive construction costs and consumes resources and generates CO2.

  The folding screen has a paper surface and thermal conductivity greater than that of cloth and is less heat-insulating. It also blocks light from the outside and darkens the interior of the room, making it unlit. (See Table 3) (See Table 4)

National Astronomical Observatory, “Science Chronology 2004” published by Maruzen Co., Ltd., published on November 30, 2003, P.A. 402

  Mounting a sheet heating element on an indoor standing interior material requires a heat source, which consumes energy and generates CO2.

  The surface of the folding screen is paper, so it is necessary to take measures against fouling, damage, getting wet with water, and fire.

Means for solving the problem

  The shield of the present invention is a slide system that can be adjusted according to the window width, a bellows system, and a cloth with low thermal conductivity and a cloth with high thermal conductivity are overlapped to improve heat insulation, and the cloth is surrounded by plastic that protects the cloth. In addition, a partition plate is provided to stop the gap air, and the periphery of the shield is fixed with rubber packing to enhance the airtight means, and the cool air is blocked from flowing into the room, and a shield with heat insulation and air tight means is manufactured.

  Woolen cloth is used because it contains a lot of air between the fibers, has low thermal conductivity, and has excellent heat insulation. (See Table 4)

  Silk fabric cloth has low thermal conductivity, moisture absorption function "moisture absorption", moisture absorption function that quickly absorbs moisture to the surface of the cloth, and fiber moisture absorption function "moisture release" Even if moisture and moisture adhere to the cloth of the shield, moisture is “released” to prevent moisture and water from being deteriorated in heat insulation. (See Table 4)

  At the first climb of Everest of the Japan Mountaineering Association, wool was used for underwear, and feather clothing was made of silk cloth for the U.S. Self-Defense Forces parachute. Wool and silk cloth proved to be an excellent countermeasure against cold in high-lying areas. Take advantage of its low conductivity and excellent thermal insulation. (See Table 4)

Naokata Kitayama, “How to Learn Heat Transfer Engineering”, published by Ohmsha, February 50, 2007, p. 21

  The height of the cloth of the shielding body is set to the height of the sitting waist or the height of the shielding body.

  The upper part of the shield is made of plastic and is well-lighted, and the lower part is a heat insulating cloth.

  The surface of the shield is slightly less flammable than paper, and the cloth is protected by a plastic that is not easily damaged or damaged. The plastic may be transparent, translucent, or opaque. (See Table 5)

The invention's effect

The outside air temperature becomes 0 ° C, the floor of the inflow place of cold air accumulates in a range of 100cm above the tatami surface, the inflow place of cold air is surrounded by a shield, the inflow of cold air is blocked, and the temperature behind the shield The temperature of the inside of the shield and the room temperature is 10 ° C, and the temperature difference disappears to prevent the body from cooling down and the plant from withering. It is 2700cm away from the window and 1200cm above the tatami surface. The temperature is 10 ° C. and there is no temperature difference in the room. (See Table 6)

  In winter, natural convection heat transfer type oil stove and electric kotatsu are used as a heater in the winter. The outside air temperature is 1 ° C, and a heat-insulating resin film with an air layer formed on the window glass is applied as a countermeasure against cold. A plastic plate is attached to the shoji door, and the shield is placed in front of the shoji door. The temperature on the back side of the shield drops to 8.6 ° C, but the inner temperature is 18.7 ° C, 900 cm away from the window, and 400 cm in height. The temperature difference is 20 ° C. and the temperature difference is 1.3 ° C. The temperature difference between the room and the inside of the shield is 2 ° C. or less, so that the body is protected from cold and cold. (See Table 7)

  In the winter bedroom, there is no heater, the outside temperature on snowy night falls to 0 ° C, a heat-insulating resin film with an air layer formed on the glass of the window is pasted, and a transparent resin plate is attached in front of the shoji door. The shield is installed, the temperature on the back side of the shield drops to 4 ° C, the inside temperature is 10.5 ° C, the room temperature is 12 ° C, the temperature difference is 1.5 ° C, and the shield flows into the cold room. The temperature difference between the inside of the shield and the room is 2 ° C or less, and the body can be protected from cold and cold. (See Table 10)

  The shield cloth is protected by plastic and can be protected from fouling, breakage, water and fire. However, if the plastic and cloth are treated with a flame retardant, the flame resistance of the shield is improved.

  Even if the plant is placed near the window in winter, there is no temperature difference between the room and the inside of the shield of the present invention, and there is no need to move to the room at night.

  Even if elderly people ride on vehicles such as high-speed cars, bullet trains, airplanes, ships, etc. in winter and sit on the window side, the shield of the present invention blocks the flow of cold air to the passage side, so the coldness of the body disappears No need to move to aisle seats.

  In summer, the window glass and sash frame are exposed to direct sunlight, and the temperature at the window rises. However, the shield of the present invention is excellent in heat insulation and prevents the inflow of warm air. The temperature inside the back of the shield is 5 ° C. Reduced cooling costs and CO2 reduction.

  By installing the shield of the present invention at a place where cold air flows in at room temperature in winter, there is no temperature difference in the room and there is no need to increase the temperature of heating, and energy can be saved and CO2 can be reduced.
