Abstract

PROBLEM TO BE SOLVED: To prevent a low temperature burn from being produced during a sleep owing to an electric carpet used by being laid on a lower surface of a sleeping tool by a method wherein when a low temperature burn prevention switch is turned on, the temperature once becomes high, and a timer is actuated after the elapse of a predetermined time to set surface temperature of the electric carpet to the low temperature burn prevention temperature. SOLUTION: In this electric carpet 1, a low temperature burn prevention switch 11 is provided on a controller 4. Once the low temperature burn prevention switch 11 is turned on, surface temperature of the carpet is first made a high temperature. The temperature in this case is set within 40 deg.C to 70 deg.C. The high temperature state is continued for 30 minutes to 1 hour owing to the action of a timer 12, and then the temperature is automatically set to low temperature burn prevention temperature. Once the low temperature burn prevention switch 11 is turned on, the temperature is set to high temperature, and simultaneously a pilot lamp 13 flushes for a predetermined time, for example 30 minutes. With the elapse of 30 minutes, the surface temperature of the carpet is automatically switched to the low temperature burn prevention temperature.

2. Description of the Related Art In recent years, electric carpets, which are particularly used for heating indoors of homes, have been widely used as heating devices for warming the human body from the floor surface. For example, they are used in bedrooms in winter or in cold regions. Since it is laid under the bedding and can warm the human body together with a comforter, it is often used as one of the bed heaters for the elderly and the sick.

However, even if the set heating temperature of the electric carpet is a relatively low temperature such as 40 ° C. to 60 ° C., the bedding itself is kept at 40 ° C. or more due to the heat retaining effect of the bedding after long-term use. It becomes a temperature, and while touching the same place for a long time, depending on the constitution and condition of the user, the protein in the warmed part of human skin is destroyed,
The phenomenon of so-called low-temperature burns occurs, which causes erythema and blisters to reach deep inside the skin.

Regarding such a low temperature burn, a warning is given in the instruction manual as a safety precaution when the electric carpet is sold. However, the user usually does not notice the warning or ignores it. There are examples of burns. In particular, there are many elderly and sick people who lay and use bedclothes on electric carpets. Moreover, I often don't immediately notice that I got a low-temperature burn, and I may get a low-temperature burn without knowing it while sleeping.

In the electric carpets used in recent years,
Although some controllers have switches for combating ticks, there is no electric carpet that has a function of preventing low-temperature burns during use. On the other hand, when laying bedclothes on an electric carpet and sleeping, the bedclothes are initially cold, so it is necessary to actively warm the bedclothes to an appropriate heating temperature with the electric carpet.
The low-temperature burn described above does not occur when the human body is warmed up for a short time, depending on the set heating temperature, and in this case, the heat from the electric carpet heater reaches the human body of the user who sleeps through the bedding. It takes a certain amount of time, and it is also known that once a person enters a warmed bedclothes, the heat is retained for a long time by the body temperature and the bedclothes do not immediately cool.
