Improved indoor heater

Abstract

The invention provides an improved indoor heater. The improved indoor heater comprises a panel, a shell, an air blowing module, a ventilation module and a heating module; an illumination module, an intake grid plate and an exhaust grid plate are mounted on the panel; a first intake port, a second intake port and an exhaust port are formed in the end surface of the shell; an air outlet is formed inthe side surface of the shell; a first volute and a second volute are arranged in the shell; a first exhaust way is surrounded by the first volute; a second exhaust way is surrounded by the second volute; a thermal insulation surrounding plate is projected on the exhaust port for surrounding the heating module; the heating module is accommodated in the thermal insulation surrounding plate, and isaligned to the exhaust grid plate; the intake grid plate respectively conducts with the first intake port and the second intake port; the first air way communicates with the first intake port and theexhaust port; the second air way communicates with the second intake port and the air outlet; the air blowing module is mounted in the first air way; the ventilation module is mounted in the second air way; a thermal insulation back plate is arranged on the back surface of the illumination module, covers the back surface of the illumination module, and is fixed with the panel; and a gap is formedbetween the illumination module and the thermal insulation back plate.

Description

technical field [0001] The invention belongs to the technical field of heaters and relates to an improved indoor heater. Background technique [0002] Yuba is a small household appliance product for bath that combines multiple functions such as bathroom heating, bathroom ventilation, and lighting. The PTC heating element of the existing air-heating Yuba generates a relatively high temperature under normal working conditions, and a fan is needed to blow the heat out of the PTC heating element to realize heating. Sustained high temperature will cause the temperature of the external parts of the PTC heating element to rise, and harmful gases will be produced when melting, and even the possibility of fire may occur, which will affect the life and safety performance of the entire electrical appliance, resulting in a greatly increased unsafe factor. The external structure of the PTC heating element of the existing air-heating Yuba is not ideal, and the machine life and safety fac...
