In the warm air blower in the prior art, under the condition that the heater assembly comprises a plurality of heater bodies, as a large gap exists between two adjacent heater bodies, the problem that cold air sucked into the warm air blower is mixed into hot air is caused, so that the air outlet temperature is influenced, and the heating effect is reduced.
In order to solve the above problems, the warm air blower of the present invention will be described below with reference to fig. 1.
As shown in fig. 1, a fan heater according to an embodiment of the present invention includes: a housing 4, a heating assembly and a fan 2. Wherein, the shell 4 is made of plastic.
The heating assembly and the fan 2 are arranged in the shell 4 and are sequentially arranged along the air supply direction; the shell 4 is respectively provided with an air inlet and an air outlet.
The heating assembly comprises a plurality of heater bodies 1, and the number of the heater bodies 1 is selected according to actual working conditions, and is not particularly limited herein. The plurality of heater bodies 1 are sequentially arranged at intervals; a plurality of independent air inlet channels are arranged in the shell 4, and the air inlet channels correspond to the heater bodies 1 one to one.
For example, the number of the heater body 1 is three, and the number of the air inlet channels is also three, and at this time, cool air entering from the air inlet is heated by the heater body 1 after passing through the air inlet channels.
In the embodiment of the utility model, the gaps among the plurality of heater bodies 1 are greatly reduced by the independent air inlet channels, under the condition that the air inlets are over against the heater bodies 1, airflow cannot pass through the gaps among the heater bodies 1, the airflow does not flow out of the air outlets and is not a cold-hot mixed airflow, the air inlet channels are not interfered with each other, and the air inlet directions of the air inlet channels are vertical to the heater bodies 1, so that the working efficiency of the heater bodies 1 can be maximized to the greatest extent.
Compared with the existing fan heaters which share the same air inlet duct, the fan heater provided by the embodiment of the utility model reduces the air leakage quantity among the heater bodies 1 and improves the heating efficiency; on the other hand, air can be supplied through the independent air inlet duct, so that the air supply efficiency is improved, the heating efficiency is further improved, and the product competitiveness is enhanced.
On the basis of the above embodiment, each air inlet duct includes two partition plates, and the two partition plates are arranged along the width direction of the heater body 1.
It should be noted that the partition plate may be made of plastic, and the length of the partition plate is equal to the length of the heater body 1. Wherein, the area between the two partition plates forms the air inlet duct.
In another embodiment of the present invention, a baffle 3 is disposed between two adjacent heater bodies 1, and an air inlet duct is formed between two adjacent baffle 3.
Wherein one end of the barrier 3 may be detachably mounted on the inner wall of the housing 4 in order to facilitate replacement of a new barrier 3.
