説明

In this study, we showed the heat removal when the top part type exhaust was applied to the commercial electrification kitchen appliance, and examined the thermal environment at the work positions. The top part type exhaust is a method to do a more local exhaust from the top hood type exhaust.<br> The experiment was carried out by heating water with Induction Heating(IH) cooker. Two kinds of heat type were set. One was continued boiling, and another was maintained the water temperature kept at 90[°C]. We examined the heat removal efficiency and the thermal environment at the work positions from the experiments that were changed each item of "Height of the exhaust opening", "Diameter in the exhaust opening", "Diameter of the pan", and "Installation of supplementary hood". The heat removal efficiency was decreased for a large diameter of the pan in each heat type. The heat removal efficiency improved by setting up supplementary hood for a large diameter of the pan. The difference of the thermal environment at the work positions on experiment changed "Diameter in the exhaust opening" and "Diameter of the pan" was small. However, the temperature and humidity at the work position, 1,500[mm] height from floor, rose remarkably when the supplementary hood was set. The effect was occurred by the thermal plume to leak and to approach the work position. The top part type exhaust is effective to the latent heat removal. However, it is necessary to examine the installation method enough.
