Problems solved by technology

The air inlet of the existing electric fireplace generally uses a filter to block the entry of dust and flocculent impurities, and the installation of the filter will cause the air intake efficiency of the air inlet to be very low, and the need to increase the power of the fan will inevitably lead to an increase in the noise of the fan

Abstract

The invention discloses a dustproof electric fireplace. The dustproof electric fireplace comprises a box body; an intake port, an exhaust port and a fan are arranged in the box body; an intake dust removing device is arranged in the intake port, and comprises a base block and a core block; a circular through hole is formed in the base block; a first spiral groove is formed in the inner wall of the through hole; a second spiral groove is formed in the outer side of the core block; the core block extends into the through hole to splice the first spiral groove and the second spiral groove as a spiral channel; and multiple adhesive tapes are bonded and piled in the first spiral groove. The electric fireplace can effectively reduce dust and flocculent impurities to enter the box body from the intake port to prevent shortening of the life of a heating element and to prevent generation of irritant and harmful gas, and cannot influence the intake efficiency of the intake port to reduce the power of the fan and to lower the noise.

Description

technical field [0001] The invention belongs to the technical field of electric fireplaces, in particular to dustproof electric fireplaces. Background technique [0002] With the improvement of people's living standards, electric fireplaces have gradually become household heating equipment for people in winter. Electric fireplaces generally generate heat through the internal heating element and then release the heat from the electric fireplace box to the room through the fan. Due to the presence of dust and flocculent impurities in the indoor air, when the dust and flocculent impurities contact the heating element, the dust will cause local heating of the heating element. Overheating will affect the life of the heating element, and the flocculent impurities will be heated and melted to emit harmful gases with pungent odors. The air inlet of the existing electric fireplace generally uses a filter to block the entry of dust and flocculent impurities, and the installation of t...
