Description

Technical Field

[0001] This invention relates to the field of heater technology, and specifically to a heater. Background Technology

[0002] Existing dual-fan, dual-outlet heaters (such as...) Figure 1 As shown, the air outlet is usually lengthened further on the volute tongue side to increase the outlet area and expand the air supply range. However, since the volute outlet width is limited, if the outlet length is further increased, the high-speed airflow will gather on one side of the outlet in the horizontal direction, while the airflow on the other side will decrease, resulting in uneven airflow distribution in the left and right directions. If the outlet grille is too close to the volute tongue, the high-speed airflow accelerated by the impeller will gather in large quantities on the side away from the volute tongue in the vertical direction under the action of inertial force, resulting in uneven airflow distribution in the vertical direction and affecting people's bathing comfort. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defect of uneven airflow distribution at the outlet of the heater in the prior art, thereby providing a heater with uniform airflow distribution at the outlet.
