Problems solved by technology

[0003] Like the above-mentioned ceiling-embedded ventilation fan of the prior art, since its temperature controller 16 is generally arranged above or below the heater 17, in this way, when the ceiling-embedded ventilation fan is running, the temperature will pass through the temperature controller 16 and the heater. The wind of 17 will form wind resistance, and there is a problem of increasing noise

Abstract

A heating ventilating fan comprises a body frame with an opening, a fan snail shell with a built-in fan, a heater assembly fixed at an air outlet of the fan snail shell and a temperature controller for detecting the indoor temperature. The temperature controller is buried on an air path wall. The heating ventilating fan has the advantages that the thinning change of the product is achieved when the structure is simplified and noise is reduced.

Description

technical field [0001] The invention relates to a ventilating fan, in particular to a heating ventilating fan. Background technique [0002] Such as Figure 1A , Figure 1B Shown is a known heating and ventilating fan 10, which is a ceiling-embedded ventilating fan, including: a body frame 11 with an opening 12, a fan snail shell 14 with a built-in fan 13, and a heater combination fixed to the air outlet of the fan snail shell 15 and a temperature controller 16 that monitors the indoor temperature, and the temperature controller 16 is arranged above or below the heater. The ceiling-embedded ventilation fan communicates with the indoor and outdoor through pipes to realize functions such as ventilation and heating. [0003] Like the above-mentioned ceiling-embedded ventilation fan of the prior art, since its temperature controller 16 is generally arranged above or below the heater 17, in this way, when the ceiling-embedded ventilation fan is running, the temperature will pas...
