AI Technical Summary

Technical Problem

Existing linear bathroom heaters have low air supply efficiency, insufficient air convection in the bathroom, and low heating efficiency due to the external-internal circulation path, while the ventilation effect of the external-external circulation path is not ideal.

Method used

It adopts a double volute structure, with the exhaust port and air inlet located on the same side of the casing. The air outlet and ventilation channel are equipped with guide plates and partition plates. Combined with the switching component, it can realize multiple modes of operation, and the airflow circulation path is internal-internal or internal-external circulation.

Benefits of technology

It improves heating and ventilation efficiency, enhances air supply, saves space, and achieves higher cost performance, with a single unit efficiency approaching that of two bathroom heaters.

Abstract

The utility model provides a bathroom internal circulation linear bath heater which comprises a machine shell, the machine shell is provided with an air outlet and an air inlet, and the air outlet and the air inlet are formed in the same side wall of the machine shell. An air outlet channel is formed in the machine shell, the air outlet is formed in the middle of the air outlet channel, the two ends of the air outlet channel are each provided with an air blowing volute, air outlets of the air blowing volutes are communicated with the air outlet through the air outlet channel, and a heater is arranged at the air outlet. According to the internal circulation linear bath heater for the bathroom, on the basis of an existing bath heater, the two air blowing volutes are adopted, the air supply channel is improved, the two air blowing volutes can supply air to the air exhaust opening or the air exchange opening at the same time, and therefore the utilization rate of the single air blowing volute is greatly improved, the air supply effect is improved, and the cost performance of the single bath heater is higher; meanwhile, the air outlet and the air inlet are formed in the same side wall of the machine shell, convection of airflow in the bathroom is more sufficient during heating and ventilation, and the heating and ventilation efficiency is further improved.
