Description

  Regarding the heat insulation in the bathroom using hot water and heat storage material for the purpose of preventing accidents in the bathroom of elderly people in winter, the improvement of the prior application Japanese Patent Application No. 11-353472 and JP 2001-132968 “Bathroom Heating” Is.

  Increasing number of elderly people, bathrooms and toilets, etc., and accidents involving elderly people in the winter are increasing in cold places. As countermeasures, toilet heating and toilet seat warming are commercialized for toilets, and bathroom heating is commercialized for bathrooms. However, this bathroom heater has a structure in which warm air blows out from the ceiling, and when used during bathing, it is not comfortable due to warm air from above.

  Japanese Patent Application No. 11-353472 of the prior application is one in which a heat storage material and a heater for heating the heat storage material are built into the bathroom mat and the chair for the bathroom. The pipe heater is built in the inside, and the heat storage material is directly heated and charged to enable high efficiency.

Problems to be solved by the invention

  The problem to be solved by the present invention is that the cold floor in the bathroom in winter has a great shock to the bare feet of the elderly, and for the prevention, various mats used for the floor have been commercialized. When it gets wet, the old man's bare feet are as shocked as the cold floor, trying to solve this.

Means for solving the problem

  As a means for solving this problem, the present invention includes a hot water bottle or a heat storage material built in a bathroom chair formed of a light and well-shaped resin, and is kept warm for a certain period of time depending on its charging temperature. I will try to let you.

The invention's effect

  As an effect of the invention, the effect of preventing troubles caused by temperature difference and cold, which frequently occur during bathing by elderly people in winter, can be expected.

  For the type to be used after charging, such as a heat storage material, it is effective to wrap the heat storage material after heating with a cloth that has a heat-retaining effect, or to use it in a futon that has a high heat-retaining effect, such as that. However, since it is used under such bad conditions that it is impossible to wrap it in a bathroom in winter, etc., it was tested for the purpose of keeping it warm for 2-3 hours of normal bathing time. In this test, it was possible to keep the temperature at 30 ° C under such bad conditions. This temperature does not shock the bare feet of the elderly.

  The embodiment will be described with reference to FIG. 1. The example shown in FIG. 1 is a heat insulation using a hot water bottle 4 that has been known for a long time, and a 110 ° C. heat-resistant PE resin is used for the hot water bottle 4 container. The tap 5 of the hot water bottle 4 made of EVA resin that is light and well drained is provided at the lower part of the chair 1 that does not get in the way.

  This hot water bottle type test was conducted under the conditions of a bathroom temperature of 17.6 ° C., a humidity of 82%, and a bathroom floor surface temperature of 14.3 ° C. As shown in the graph of FIG. Was sustained.

  FIG. 2 shows the heat storage material 6 used. The container of the heat storage material 6 is formed of PE heat-resisting resin or metal. A pipe heater 8 is built in the heat storage material 6 and the heat storage material 6 is directly heated and charged. Moreover, since it is used in the bathroom, the power supply connection part is fully waterproofed with the waterproof plug 7 after being heated. In this case, the bathroom chair 1 is formed of EVA resin.

  The test with the heat storage material 6 was performed under the conditions of a bathroom temperature of 18.0 ° C., a humidity of 80%, a bathroom floor temperature of 18.9 ° C., and a chair 1 upper surface temperature of 18.9 ° C. before being kept warm, FIG. According to the test record, the heat retaining effect at 30 ° C. on the upper surface of the chair 1 could be maintained for 3 hours.

  What is shown in FIG. 3 relates to a bathroom heat-insulating mat 9 made of a heat storage material 6, and the mat 9 is also formed of EVA resin. The mat 9 is a feeling that the chair 1 is greatly expanded, and this could not be tested. The thermal insulation effect is considered not to be much different from that of the chair 1.

  In this test, stearic acid with a melting point of 71 to 71, 5 ° C. was used with a thickness of 13 mm. In order to extend the heat retention time of the heat storage material 6, the thickness 10 of the heat storage material 6 should be increased. In order to raise the temperature to 30 ° C. or higher, the thickness of the resin on the upper surface 2 of the chair 1 and the mat 9 may be reduced, but if it is 30 ° C., this warming container that does not shock the bare feet of the elderly Attaching the metal foil 3 to the inner surface of the built-in chair 1 and mat 9 other than the upper surface 2 is intended to keep warm.

  It is cordless when used, and can be used with confidence, and it can be expected to have the effect of reducing troubles in the bathroom of elderly people in winter.
