Description

  The present invention relates to a cold insulation pad, more specifically, using the cooling effect of a gel-like cold insulator, for example, in a tropical night, when a human goes to sleep, this is spread over the back of the head and neck, or from the back to the back of the knee. The present invention relates to a cold insulation pad for pillows, mattresses or mattresses for cooling and obtaining a comfortable sleep.

  Summer in Japan has been hotter and humid than in the past, but recently, in urban areas, heat island phenomenon (air conditioning such as cooling, heat absorption by concrete and asphalt with large specific heat, temperature rise due to radiant heat of window reflection, etc.) ), Tropical nights, that is, nights where the minimum temperature from evening to the next morning is 25 degrees Celsius or more are increasing and prolonging. For example, according to an announcement by the Japan Meteorological Agency, the number of days in Tokyo where the daily minimum temperature is 25 ° C or higher is mostly within 10 days a year from the 1930s to the 1940s, but reaches 30 to 40 days a year after the 1990s. That's not rare. In Honshu, it was previously from mid-July to mid-August, but in recent years it has been recorded from late June to mid-September and tends to be longer.

  In general, a cooler, a fan, or the like is used as a measure to sleep well in a tropical night. However, if the cooler is operated for a long period of time, the power consumption of electricity will increase, and the physical condition will decline due to overcooling, loss of appetite, etc., which may cause summer heat and illness. The same applies to the use of a fan for a long time, and the body feels tired in order to lower the body temperature, which contributes to poor physical condition.

  Various proposals have been made to ensure a good night's sleep in a tropical night. For example, in the “cool wind shutter” of Patent Document 1 (see page 1 and FIG. 1), it is proposed that a ventilation opening is formed in a part of the shutter and the cool wind is taken into the room to try to sleep well. . In addition, the “pillow” of Patent Document 2 (see page 1 and FIG. 1) can cool the head while holding the head in a shape that matches the shape of the neck and head, and does not put a burden on the body. An object of the present invention is to provide a pillow having a long-lasting function and a good sleeping comfort, and the means for solving the problem is that the pillow is composed of a main body having a recess at the center and a cold insulator incorporated in the recess. It is characterized by opening in the central part of the side wall of the main body on the side where the neck is located. Furthermore, the “cold and warm ventilation mat” disclosed in Patent Document 3 (see page 1 and FIG. 1) has an object to provide a cold and warm ventilation mat in which the entire mat can obtain an appropriate temperature by the ventilation control function. Means are provided with a suitable ventilation space inside, a mat with a vent button that uniformly discharges a minute amount of saturated air in the mat, and a sandwiched space tank of the external cold air control box sandwiched in the center. One or more cold / warm exchange chips that can be fixed, and can be operated in three different ways, with hot air from the hot air connection port, cool air from the cold air connection port, or simply air at room temperature, A fragrance pot with a divergence hole for divergence, and a hot air / cold air area formed on the rear wall, and whether the user connects to the cold air connection port or only to the hot air connection port Fan, Su Pitch, consist of such as temperature controllers, and circumscribing formula cold blast control box can also be a mat bed-bed mattress, a technique for constituting the connection pipe is disclosed.
