おシ熱的遮断効果も強く要望されている。BACKGROUND OF THE INVENTION Generally, air curtains are attached to ceiling walls at entrances and exits of rooms, and use discharged airflow to isolate indoor and outdoor environments. Air curtain performance focuses on wind speed in terms of blocking performance, but in the case of air curtains with heaters, thermal blocking performance based on the temperature of the discharged air is also important, and thermal blocking effects are also strongly desired. .

った。For this reason, the conventional air curtain with a heater, as shown in FIG. Even when the outdoor temperature is very low, or conversely when the temperature difference between the indoor and outdoor temperatures is small, the heated air curtain always discharges air that is approximately 10°C higher than the indoor temperature. Ta.

あった。Problems to be Solved by the Invention In such a conventional configuration, when the outdoor temperature is very low compared to the indoor temperature, the hot air discharged by the air curtain with a heater does not heat up even if the indoor temperature is +10°C. If the thermal insulation effect decreases and indoor heat is released outdoors, and if the indoor temperature and outdoor temperature are almost the same, even though low-temperature warm air has a sufficient thermal insulation effect, There was a problem of wasting energy by discharging hot air with high temperature.

のである。The present invention solves these problems by providing an air heater with a heater that discharges warm air at the optimum temperature and saves energy while maintaining high thermal insulation efficiency, regardless of the temperature difference between indoors and outdoors. The purpose is to provide curtains.

ある。Means for Solving the Problem In order to solve this problem, the present invention includes two temperature sensors that sense a temperature difference, and a variable resistance element whose resistance value changes depending on the temperature difference signal detected by the temperature sensor. The heater is configured with a heater that is energized through this variable resistance element and installed at the outlet of the air curtain main body.

実施例
以下、本発明の一実施例を第１図および第２図にもとづ

電されない。In the figure, 1 is an air curtain body with a heater attached to the entrance of the room, 2 is an outdoor temperature sensor that senses the outdoor temperature, and 3 is an indoor temperature sensor that senses the indoor temperature. Signals from the outdoor temperature sensor 2 and the indoor temperature sensor 3 are given to a control circuit of a control box 4, and if the temperature sensed by the outdoor temperature sensor 2 is lower than the temperature sensed by the indoor temperature sensor 3, the signal is applied to the temperature difference. The resistance value of the variable resistance element is made to change in inverse proportion. The variable resistance element is inserted into a current supply circuit from the power source 6 to the heater 6. Note that when the temperature outside is higher than that inside the room, the control box 4 operates to cut off the power, and the heater 6 is not energized.

る。In the above configuration, the indoor temperature is higher than the indoor temperature sensor 3.
When the difference between the temperature and the temperature sensed by the outdoor temperature sensor 2 increases, the resistance value of the variable resistance element decreases, the current flowing to the heater 6 increases, the amount of heat generated by the heater 6 increases, and the air curtain body 1 with heater As the temperature of the hot air discharged rises, heat loss from the interior to the exterior is prevented, and the heat insulation effect is maintained. Conversely, when the temperature difference decreases, the resistance value of the variable resistance element increases and the current flowing through the heater 6 decreases, reducing wasteful power consumption and saving energy.

The effect is that it can be maintained in good condition and that energy can be saved.
