Auxiliary convection heat-accumulating type heater

Abstract

The invention relates to an auxiliary convection heat-accumulating type heater. The heater comprises a shell and at least one heat-accumulating device capable of storing and releasing heat energy, wherein the upper part of the shell is provided with a gas outlet, the lower part is provided with a gas inlet, the heat-accumulating device is arranged in the shell, and an air gap between the inner surface of the shell and the heat-accumulating device and the gas outlet and gas inlet of the shell constitute a convection channel. The invention is characterized in that the inside of the shell is also provided with an auxiliary convection heating element which releases heat energy to achieve the aim of accelerating the air convection in the convection channel and the convection of room air. The heater can be energized to generate heat energy in a low valley of an electricity grid and release the heat energy in a high valley of the electricity grid for heating room air; when the heat output of the heat-accumulating device is insufficient, the auxiliary convection heating element provides complementary convection heat energy by using little power, thus the indoor heating temperature can be more balanced; and the convection gas generated by auxiliary heating performs heat exchange, thus the residual heat energy in the heat-accumulating device can be brought out faster.

Description

technical field [0001] The present invention relates to a regenerative heater, in particular to an auxiliary convection regenerative heater for indoor use. Background technique [0002] At present, regenerative heaters have been more and more widely used. Chinese patent CN201302219Y discloses an automatic convection powder thermal storage electric heater, which includes a shell, an electric heating tube, and thermal storage powder. The housing is provided with upper and lower transverse partitions, and the thermal storage powder is filled in the upper and lower horizontal partitions. In the space between, the heating part of the electric heating tube is inserted into the heat storage powder, the top of the housing is provided with an upper louver, and the bottom is provided with a lower louver, and the upper transverse partition is the same as that of the housing. There is a space for forming an air collection chamber between the top, and a space for forming a pressure equa...
