Problems solved by technology

Due to the high noise generated by the airflow during the transportation process, the overall sound of the hot water equipment is loud during operation, which seriously reduces the user experience of the product
At the same time, due to the flaws in the structural design of the volute itself, the vortex generated in the internal air duct of the centrifugal fan system also aggravates the noise of the entire system

Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0033] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent the only embodiments.

Abstract

The invention discloses a fan shell structure and a fan system of hot water equipment. According to the fan shell structure and the fan system of the hot water equipment, airflow enters a first ventilation flow channel from a first air inlet, then flows into a second ventilation flow channel from a first through hole; the airflow flowing into the second ventilation flow channel flows into a firstairflow cavity channel and is finally discharged from a first air outlet; due to the fact that the airflow flows through two through holes, namely the first through hole and a second through hole in the circulation process, the flowing airflow is filtered through the first through hole and the second through hole, and disordered amplitude and frequency in the airflow are eliminated, so that airflow frequency spectrum is changed in the flowing process, noise generated during airflow circulation is reduced, and user experience of a product is effectively improved; and meanwhile, an air inlet path is changed, so that the airflow sequentially flows through the first ventilation flow channel, the first through hole, the second ventilation flow channel and the second through hole before enteringthe first airflow cavity channel, so that flowing of the airflow is greatly improved, and the situation that aerodynamic noise of the product is increased due to direct flow straight-through of the airflow in the fan shell structure can be avoided.

Description

technical field [0001] The invention relates to the technical field of hot water equipment, in particular to a fan casing structure and a fan system of the hot water equipment. Background technique [0002] In the traditional technology, the fan systems used for gas water heaters or heating furnaces basically use centrifugal fans, whose structure generally includes a fan and a volute. During actual use, the air flow directly enters the impeller space from the first air inlet of the volute, and then is discharged from the air outlet. Due to the high noise generated by the airflow during the transportation process, the hot water equipment makes a loud sound when it is running, which seriously reduces the user experience of the product. At the same time, due to the flaws in the structural design of the volute itself, the vortex generated in the internal air duct of the centrifugal fan system also aggravates the noise of the entire system.
